Global, regional, and national mortality among young people aged 10-24 years, 1950-2019: a systematic analysis for the Global Burden of Disease Study 2019

Association of reproductive lifespan and age at menopause with depression: Data from NHANES 2005-2018

BACKGROUND

The association between reproductive lifespan and depression in older women is unclear. We conducted this analysis to explore whether a shorter reproductive lifespan is associated with higher odds of depression, while also considering the age at menarche and age at menopause.

METHODS

This observational study used data from the National Health and Nutrition Examination Survey (NHANES), which was conducted between 2005 and 2018. Reproductive lifespan was defined as years from age at menarche to age at menopause. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Multivariable logistic regression models were used to explore the relationship between the association of reproductive life span, age at menarche and age at menopause with the incidence of depression.

RESULTS

Totally, 2947 patients aged 60 and above were enrolled in the trial, with 241 individuals (8.18 %) diagnosed with depression. Higher odds of depression were found to be significantly correlated with a shorter reproductive lifespan [Odds Ratio (OR) = 0.95, 95 % Confidence interval (CI) = 0.92-0.98] or an earlier ager at menopause (OR = 0.95, 95 % CI = 0.92-0.99), according to the results of multivariable logistic regression analysis after full adjustment. Subgroup analysis and interaction tests indicated a similar association.

LIMITATIONS

The cross-sectional study could not yield any conclusions regarding causality.

CONCLUSION

In this large cross-sectional study, our result suggested that populations with a shorter reproductive lifespan or an earlier age at menopause were significantly more likely to have depressive symptoms in older U.S. women. Further large-scale prospective studies are warranted for a comprehensive analysis of the role of the reproductive lifespan and age at menopause in depression.

Remote neurological evaluation reliably identifies patients eligible to endovascular therapy while non-eligible to intravenous thrombolysis

INTRODUCTION/BACKGROUND

Early identification of suspected stroke patients who might be eligible for a reperfusion strategy is a daily challenge in the management of patient referrals. The aim of this study was to evaluate the performance of a remote medical assessment in identifying patients eligible for endovascular therapy (EVT) while not eligible for intravenous thrombolysis (IVT), compared with a decision based on bedside clinico-radiological data.

METHODS

Patients admitted to the emergency department for acute neurological symptoms lasting for less than 24h were prospectively included. Assessment of the clinical severity and medical history was performed simultaneously by two vascular neurologists (VNs), one remotely using a mobile telemedicine solution (NOMADEEC), the other at the bedside. RACE score was calculated from the NIHSS score. At the end of the evaluation, both VNs quoted their treatment convictions (IVT/EVT). Final therapeutic decision following brain and vascular imaging was recorded and compared to remote and bedside predictions. The performances of three different conditions were evaluated: complete medical evaluation (NIHSS+medical history), NIHSS score alone, and RACE score alone. Remote and bedside performances were also compared. Diagnostic accuracy parameters (sensitivity, specificity, positive and negative predictive values) of each condition were estimated, along with their two-sided 95% binomial confidence intervals.

RESULTS

Out of 215 enrolled patients, 186 had a complete evaluation, 91 (54.3%) were diagnosed with an ischemic stroke or transient ischemic attack and 46 (24.7%) had an intracranial occlusion. Considering the three conditions evaluated remotely, RACE score-based decision provided the best sensitivity 54.6% [95% CI 23.4; 83.2]/specificity 80.6% [73.9; 86.2] combination. However, the complete medical evaluation had the best specificity (88.6% [82.9; 92.9] compared to RACE scores alone (P=0.038). Remote and bedside performances did not differ (κ=0.68 [0.59; 0.77]).

DISCUSSION/CONCLUSION

This real-life study performed in the setting of emergency demonstrates that remote medical evaluations including recording of extensive medical information and NIHSS examination to address patient's eligibility to revascularization treatment is swiftly feasible and is as effective as bedside prediction to EVT and/or IVT. Remote standardized medical evaluation might improve the decision of patients' primary orientation and avoid overcrowding of comprehensive stroke centres.

Homoplantaginin alleviates intervertebral disc degeneration by blocking the NF-κB/MAPK pathways via binding to TAK1

Intervertebral disc degeneration (IVDD) is a common degenerative disease which is closely related to low back pain (LBP) and brings huge economic and social burdens. In this study, we explored the therapeutic effects of Homoplantaginin (Hom) for IVDD due to its convincing anti-inflammatory and antioxidant functions. TNF-α was used to simulate the inflammatory environment for nucleus pulposus (NP) cells in vitro. We verified that Hom could alleviate the TNF-α-induced inflammation and disturbance of ECM homeostasis through blocking the NF-κB/MAPK signaling pathways. Subsequently, we screened the binding targets of Hom and confirmed that Hom could directly bind to TAK1 and inhibit its phosphorylation to down-regulate the inflammation-related pathways. The therapeutic effects of Hom on IVDD were further validated through a needle puncture rat model in vivo. Overall, Hom was a promising small molecule for IVDD early intervention, possessing huge clinical translational value.

Global, regional, and national trends in metabolic risk factor-associated mortality among the working-age population from 1990-2019: An age-period-cohort analysis of the Global Burden of Disease 2019 study

BACKGROUND

Metabolic diseases contribute significantly to premature mortality worldwide, with increasing burdens observed among the working-age population (WAP). This study assessed global, regional, and national trends in metabolic disorders and associated mortality over three decades in WAP.

METHODS

Data from the Global Burden of Disease 2019 study were leveraged to assess global metabolism-associated mortality and six key metabolic risk factors in WAP from 1990-2019. An age-period-cohort model was employed to determine the overall percentage change in mortality.

RESULTS

The 2019 global metabolic risk-related mortality rate in WAP rose significantly by 50.73%, while the age-standardized mortality rate declined by 21.5%. India, China, Indonesia, the USA, and the Russian Federation were the top contributing countries to mortality in WAP, accounting for 51.01% of the total. High systolic blood pressure (HSBP), high body mass index (HBMI), and high fasting plasma glucose (HFPG) were the top metabolic risk factors for the highest mortality rates. Adverse trends in HBMI-associated mortality were observed, particularly in lower sociodemographic index (SDI) regions. HFPG-related mortality declined globally but increased in older age groups in lower SDI countries.

CONCLUSIONS

Despite a general decline in metabolic risk-related deaths in WAP, increasing HBMI- and HFPG-related mortality in lower SDI areas poses ongoing public health challenges. Developing nations should prioritize interventions addressing HBMI and HFPG to mitigate mortality risks in WAP.

Knowing how to swim and drowning prevention in children aged 10 to 14 years. Systematic review

PURPOSE

Drowning is 1 of the 10 leading causes of death due to unintentional injuries in children and adolescents worldwide. Knowing how to swim has been traditionally associated with water safety. However, its conceptualization may vary across studies, leading to different measurements and effects on the risk of drowning. This review sought to understand the current state of scientific evidence associating both issues.

OBJECTIVES

To identify conceptualizations of knowing how to swim and to analyze the evidence indicating whether "knowing how to swim" may be a protective or a risk factor for unintentional drowning in children aged 10 to 14 years.

METHOD

A systematic review of observational etiology studies was conducted, considering original peer-reviewed research published up to the year 2020. Databases including PubMed, Cochrane Central, Tripdatabase, Science Direct, Epistemonikos, Bvs and Bireme were searched for studies associating swimming skills as a risk or a protective factor for drowning (10-14 years). Study quality was assessed, and quantitative data were synthesized (without performing a meta-analysis).

RESULTS

A total of 6,508 results were identified, with only 6 studies meeting the criteria for inclusion in the final cohort. It was evidenced that the exclusive possession of swimming skills, without a concurrent understanding of water safety, is associated with increased exposure to aquatic environments. Consequently, this may increase the risk of drowning.

CONCLUSIONS

Among children aged 10 to 14 years, there is insufficient evidence regarding whether knowing how to swim serves as a protective factor against drowning compared to not knowing how to swim.

PRACTICAL APPLICATIONS

The insufficiency of evidence and a lack of consensus in the conceptualization of swimming as a form of knowledge underscores the need for further research. Such research is crucial for informing investments in drowning prevention interventions, particularly during early adolescence.

Adolescent Psychiatric Inpatient Episodes and Subsequent Labor Market Trajectories

PURPOSE

Adolescents with psychiatric disorders are known to be more often not in education, employment, or training (NEET) in young adulthood than their peers. However, since most of the available evidence is based on cross-sectional measurement of NEET, there is less evidence on the processes underlying these differences in labor market disadvantage. We assessed these processes by examining transitions between NEET and non-NEET states across young adulthood and the differences in these transitions by adolescent psychiatric inpatient treatment.

METHODS

We used longitudinal register data on all individuals born in Finland in 1980-1984 (N = 315,508) to identify psychiatric inpatient episodes between ages 10 and 19 and NEET between ages 20 and 34. We modeled the transitions between NEET and non-NEET states and the impact of psychiatric disorders on these transitions with multistate models.

RESULTS

Individuals who had psychiatric inpatient episodes in adolescence started their labor market careers as NEET twice as often as their peers. They were also more likely to transition into NEET states and less likely to transition out of NEET. In total, individuals with a history of psychiatric episodes spent from 1.8 to 6.9 more years as NEET between the ages 20 and 34 than their peers, depending on sex, baseline NEET, and diagnostic group.

DISCUSSION

Adolescents with severe psychiatric disorders are highly vulnerable in terms of labor market outcomes throughout their early adulthood. Supportive measures are required both at the start of employment trajectories and during later career stages.

Predictors of male loneliness across life stages: an Australian study of longitudinal data

BACKGROUND

Despite growing recognition of loneliness as a global public health concern, research on its occurrence and precipitants among men across different life stages remains limited and inconclusive. This study aims to address this gap by investigating the prevalence and predictors of loneliness among a large, representative data set of Australian adult men.

METHODS

The study used longitudinal data from waves 2-21 of the Household, Income and Labour Dynamics in Australia (HILDA) Survey, including men aged 15-98. Estimating linear fixed effects regressions that account for unobserved time-invariant individual heterogeneity, a single-item measure of loneliness was regressed on a set of selected explanatory variables over different parts of the life course.

RESULTS

Increased social isolation, romantic partnership dissolution, having a long-term disability, and stronger beliefs that the man, rather than the woman, should be the breadwinner of the household, are associated with greater loneliness. Frequent social connection, having a romantic partner, and high neighbourhood satisfaction are protective against loneliness. The findings also reveal several differences in the predictors of loneliness over the life course. Job security is especially important for younger men, whereas for older men volunteering and less conservative gender role attitudes are important factors that can decrease loneliness.

CONCLUSIONS

The results emphasise the need to consider age-specific factors and societal expectations in understanding and addressing loneliness amongst men. Additionally, the findings underscore the importance of raising awareness about the impact of societal norms and expectations on men's mental health. The results offer valuable insights for policymakers, healthcare providers, and researchers to develop effective strategies and support systems to combat loneliness and promote well-being among men.

An examination from 1990 to 2019: investigating the burden of knee dislocation on a global scale

Background

The literature on the disease burden of knee dislocation is lacking. The aim of the study is to systematically assess the global burden, trends, causes, and influencing factors of knee dislocation.

Methods

The incidence and years lived with disability (YLDs) of knee dislocation were assessed globally, as well as at the regional and national levels from 1990 to 2019. Subsequent analyses focused on the age and gender distribution related to knee dislocation. An investigation into the main causes of knee dislocation followed. Finally, the Pearson correlation between age-standardized rates and social-demographic index (SDI) was calculated.

Results

Although the age-standardized incidence and YLDs rate of knee dislocation decreased over the past 30 years, the incidence and YLDs number increased. The disease burden remained higher in males compared to females. Males and females showed different patterns of incidence rates in each age group, but their YLDs rates were similar. Over the past 30 years, the disease burden of knee dislocation increased in the older population while declining in the younger population. Falls had consistently emerged as the most important cause for both incidence and YLD rates. Additionally, a positive correlation between SDI and the disease burden of knee dislocation was found.

Conclusion

The disease burden of knee dislocation remains heavy. It is essential to recognize the evolving epidemiology of knee dislocation. Utilizing data-driven assessments can assist in formulating public health policies and strategies to improve overall well-being.

Sex-specific association of serum dehydroepiandrosterone and its sulfate levels with osteoporosis in type 2 diabetes

INTRODUCTION

This study is to investigate the relation between serum dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) levels and the risk of osteoporosis in patients with T2DM.

MATERIALS AND METHODS

This cross-sectional study involved 938 hospitalized patients with T2DM. Linear regression models were used to explore the relationship between DHEA and DHEAS and the BMD at different skeletal sites. Multinominal logistic regression models and the restricted cubic spline (RCS) were used to evaluate the associations of DHEA and DHEAS with the risks of osteopenia and/or osteoporosis.

RESULTS

In postmenopausal women with T2DM, after adjustment for confounders including testosterone and estradiol, DHEA showed a significant positive correlation with lumbar spine BMD (P = 0.013). Moreover, DHEAS exhibited significant positive correlations with BMD at three skeletal sites: including femoral neck, total hip, and lumbar spine (all P < 0.05). Low DHEA and DHEAS levels were associated with increased risk of osteopenia and/or osteoporosis (all P < 0.05) and the risk of osteoporosis gradually decreased with increasing DHEAS levels (P overall = 0.018, P-nonlinear = 0.559). However, DHEA and DHEAS levels in men over the age of 50 with T2DM were not associated with any of above outcomes.

CONCLUSION

In patients with T2DM, independent of testosterone and estradiol, higher DHEA and DHEAS levels are associated with higher BMD and lower risk of osteopenia/osteoporosis in postmenopausal women but not men over the age of 50.

Multiple Causes of Death Associated with Pediatric Cardiopulmonary Arrest from 1996 to 2019 in Brazil

BACKGROUND

In pediatrics, cardiopulmonary arrest (CPA) is associated with high mortality and severe neurologic sequelae. Information on the causes and mechanisms of death below the age of 20 years could provide theoretical support for health improvement among children and adolescents.

OBJECTIVES

To conduct a population analysis of mortality rates due to primary and multiple causes of death below the age of 20 years in both sexes from 1996 to 2019 in Brazil, and identify the frequency in which CPA was recorded in the death certificates (DCs) of these individuals and the locations where the deaths occurred, in order to promote strategies to improve the prevention of deaths.

METHOD

Ecological time-series study of deaths below the age of 20 years from 1996 to 2019, evaluating the mortality rates (MRs) and proportional mortality (PM) by primary cause of death. We analyzed the percentages of CPA recorded in any line of the DC and the location where the deaths occurred. We calculated the MRs per 100,000 inhabitants and the PM by primary cause of death under the age of 20 years according to sex and age group, the percentages of death from primary causes by age group when CPA was described in any line of Parts I and II of the DC, and the percentage of deaths from primary causes according to their location of occurrence. We retrieved the data from DATASUS, IBGE, and SINASC.

RESULTS

From 1996 to 2019, there were 2,151,716 deaths below the age of 20 years in Brazil, yielding a mortality rate of 134.38 per 100,000 inhabitants. The death rate was highest among male neonates. Of all deaths, 249,334 (11.6%) had CPA recorded in any line of the DC. Specifically, CPA was recorded in 49,178 DCs between the ages of 1 and 4 years and in 88,116 of those between the ages of 29 and 365 days, corresponding, respectively, to 26% and 22% of the deaths in these age groups. These two age groups had the highest rates of CPA recorded in any line of the DC. The main primary causes of death when CPA was recorded in the sequence of death were respiratory, hematologic, and neoplastic diseases.

CONCLUSION

Perinatal and external causes were the primary causes of death, with highest MRs under the age of 20 years in Brazil from 1996 to 2019. When multiple causes of death were considered, the main primary causes associated with CPA were respiratory, hematologic, and neoplastic diseases. Most deaths occurred in the hospital environment. Better understanding of the sequence of events in these deaths and improvements in teaching strategies in pediatric cardiopulmonary resuscitation are needed.

Statistical estimation of fatal and serious injuries saved by iRAP protocols in 74 countries

OBJECTIVE

Road traffic crashes cause 1.19 million deaths and millions more injuries annually. The persistently high burden has drawn attention from national and international stakeholders worldwide. Unsafe road infrastructure is one of the major risk factors for traffic safety, particularly in low- and middle-income countries.

METHODS

Aiming to eliminate high-risk roads in all countries, the International Road Assessment Programme (iRAP) developed a robust and evidence-based approach to support country transportation agencies.

RESULTS

Thus far, the iRAP protocols have been used to collect 1.8 million kilometers of Crash Risk Mapping and 1.5 million kilometers of Star Rating and FSI estimations in 128 countries. Deploying an observational before-and-after (or pre-post) study design, this report estimated the fatal and series injuries (FSI) saved through use of the iRAP protocols. The study is based on 441,753 kilometers of assessed roads from 1,039 projects in 74 countries. Our results show that the implementation of iRAP's proposed countermeasures saves about 159,936 FSI annually. Throughout the lifetime of the implemented countermeasures, a total of 3.2 million FSI could be saved.

CONCLUSION

While quantifying the success of the iRAP protocols, our results suggest an opportunity to save many millions more lives on the roads through expanding iRAP implementation to more regions and countries.

Prevalence and correlates of sleep disturbance among adolescents in the eastern seaboard of China

BACKGROUND

Sleep disturbances are serious public health issues that warrant increased attention, especially in adolescents. The aim of this study was to investigate the prevalence and factors associated with sleep disorders among urban adolescents in China.

METHODS

This study utilized an online survey to assess the demographic characteristics and mental health status of secondary school students in Lianyungang City. The Patient Health Questionnaire-9 (PHQ-9) was used to evaluate sleep disturbances in adolescents. The seven-item Generalized Anxiety Disorder (GAD-7) assessed anxiety symptoms, and the Perceived Social Support Scale (PSSS) was used to measure perceived social support.

RESULTS

Among 3443 adolescents, the prevalence of sleep disorders were 10.8%, with significantly higher proportions of sleep disorders (13.7% VS 8.3%, P < 0.001) among female adolescents when compared to males. Binary regression analysis revealed that anxiety symptoms (OR = 1.305, 95% CI: 1.269-1.342, P < 0.001) was risk factor for sleep disturbances, and significant other support (OR = 0.944, 95% CI: 0.896-0.994, P = 0.028) and good annual household income (OR = 0.616, 95% CI: 0.394-0.963, P = 0.034) were protective factors. Furthermore, multinomial logistic regression analysis showed that age, sex, and anxiety symptoms were associated with an elevated risk of experiencing more frequent sleep disturbances (all P < 0.05).

CONCLUSIONS

We have found that 10.8% of adolescents experience sleep disorders, and it is evident that various factors can influence healthy sleeping. These results underscore the significance of addressing these factors to enhance sleep health among this population.

On a collision course: fatal motorcycle and bicycle accidents of adolescents in Finland from 2008 to 2019

BACKGROUND

Transport injuries are a major cause of mortality among adolescents. Our aim was to evaluate the circumstances and trauma associated with fatal accidents involving adolescents and two-wheeled vehicles.

METHODS

We analyzed retrospective data from the Finnish Crash Data Institute from 2008 to 2019 involving 10- to 24-year-old victims of fatal traffic accidents who were injured while riding a bicycle, moped or motorcycle. We collected data on patient characteristics, accident circumstances and possible treatment. These fatalities were compared with national mortality rates among the respective age groups.

RESULTS

We identified 147 fatalities over the 12-year period involving 20 bicycle, 50 moped and 77 motorcycle riders. Most accidents involved males (n = 121, 82%). Less than half of vehicles were in good condition (46%); motorized vehicles were often illegally tuned (37%) or had tire problems (31%). Most of the accidents were collisions with another vehicle (n = 99, 67%) or other objects (n = 35, 24%). In 94% of cases, the Injury Severity Score was >25. Head injury was the most common cause of death (62%). Among 15-year-olds, every fifth death was due to accidents on two-wheeled vehicles.

CONCLUSIONS

Fatal transport accidents among adolescents comprise several elements that should be incorporated into driver's education and in case of minors, also communicated to parents. These include the condition of the vehicle, proper helmet use and effects of speed on both control of the vehicle and the consequences of a possible collision.

Patterns of adverse childhood experiences and their associations with mental distress, substance use and sexual risk behaviors in Sub-Saharan Africa

BACKGROUND

Multiple adverse childhood experiences (ACEs) are associated with poor sexual and mental health outcomes in low- and middle-income countries (LMICs). Less well understood is how discrete and gendered clustering of ACEs may influence health.

OBJECTIVE

To assess how multiple ACEs co-occur and how dominant patterns of co-occurrence are associated with mental distress, substance use, and sexual risk behaviors among young women and men in Sub-Saharan Africa.

PARTICIPANTS AND SETTING

We used pooled data of young men and women aged 19-24 from comparable, nationally representative Violence Against Children and Youth Surveys (VACS) conducted in Cote d'Ivoire, Kenya, Lesotho, Mozambique, and Namibia (nf = 7183; nm = 2207).

METHODS

We estimated sex-disaggregated latent classes of six ACEs among young women and men. We ran Bolck-Croon-Hagenaars (BCH) distal outcome analysis to test the sex-stratified relationships between ACEs latent classes and health outcomes.

RESULTS

A six class solution best fit the female data. Classes included witnessing violence and experiencing physical violence (PV); experiencing PV; high ACEs; witnessing community violence; orphanhood; and low ACEs exposure. Among males, the best-fitting three-class solution included experiencing PV and witnessing community violence; high ACEs; and low ACEs exposure. Membership in the high ACEs class was associated with mental distress among females and males, and substance use among males. No differences in sexual risk behavior were identified by class membership among either females or males.

CONCLUSIONS

Discrete clusters of co-occurring ACEs are associated with elevated odds of mental distress among females, and mental distress and substance use among males. Preventing ACEs may improve mental health among young women and men in LMICs in Sub-Saharan Africa.

Self-harm and suicide death in the three years following hospitalization for intentional self-harm in adolescents and young adults: A nationwide study

Self-harm is frequent in youths. This study aimed to assess the risk of self-harm and mortality over a three-year period following self-harm hospitalization. Data were extracted from national databases in France. All patients aged 12 to 24 years and hospitalized for self-harm in 2013-2014 were included and compared to age- and sex-matched individuals with no self-harm hospitalization during this period. Cox proportional hazards regression models were used. Overall, 34,533 individuals were hospitalized for self-harm in 2013-2014 (70.8 % females, 79.6 % self-poisoning), with a peak among females aged 14-16. Comparison with 103,599 matched controls showed significantly higher rates of past self-harm, somatic and psychiatric disorders, and dispensed drugs in youth hospitalized for self-harm. During follow-up, they significantly more often repeated self-harm (20.9 vs. 0.1 %), died from any cause (0.6 vs 0.03 %) and from suicide (0.2 vs 0.01 %), particularly during the first year. The choice of a violent self-harm means at inclusion increased the risk of suicide during follow-up. Psychiatric disorders were a significant risk factor for all outcomes. In conclusion, at least one in five youths will self-harm, and one in two hundred will die in the three years following hospitalization for self-harm. Reinforced follow-up care is necessary in this population.

The relationship between appearance anxiety and depression among students in a medical university in China: a serial multiple mediation model

Background

Appearance anxiety and depression have become common and global public health problems worldwide, especially among adolescents. However, few studies have revealed the mechanisms between them. This study aimed to explore the multiple mediating roles of interpersonal sensitivity and social support between appearance anxiety and depression among medical college students.

Methods

With 13 invalid samples excluded, 724 college students participated in our survey and completed questionnaires. The average age of 724 samples was 19.8 ± 2.02 including freshman to senior year and graduate school and above; 31.9% of the participants were male and 68.1% were female. SPSS 25.0 and Hayes' PROCESS macro were used for statistical description, correlation analysis and built multiple mediation models.

Results

Appearance anxiety can not only directly affect depression, but also indirectly affect depression through three significant mediating pathways: (1) IS (B = 0.106, 95% CI [0.082-0.132]), which accounted for 49.77% of the total effect, (2) SS (B = 0.018, 95% CI [0.008-0.031]), which accounted for 8.45% of the total effect, and (3) IS and SS (B = 0.008, 95% CI [0.003-0.014]), which accounted for 3.76% of the total effect. And the total mediating effect was 61.97%.

Limitations

It is a cross-sectional research method and the causal relationship is unclear.

Conclusions

This study found that lower interpersonal sensitivity and higher social support can effectively reduce depression caused by appearance anxiety among college students. The schools and relevant departments should take measures to reduce the interpersonal sensitivity of college students and establish reliable social support, so as to reduce the occurrence of depression.

Mendelian randomization of chronic hepatitis B and cardiovascular disease

Background

Evidence from observational studies suggests that chronic hepatitis B (CHB) is associated with cardiovascular disease (CVD). However, results have been inconsistent and causality remains to be established. We utilized two-sample Mendelian randomization (MR) to investigate potential causal associations between CHB and CVD, including atherosclerosis, coronary heart disease, hypertension, and ischemic stroke.

Methods

The analysis was conducted through genome-wide association studies (GWAS), considering chronic hepatitis B as the exposure and cardiovascular disease as the endpoint. The primary method for evaluating causality in this analysis was the inverse-variance weighted (IVW) technique. Additionally, we employed the weighted median, MR-Egger regression, weighted mode, and simple mode methods for supplementary analyses. Finally, heterogeneity tests, sensitivity analyses, and multiple effects analyses were conducted.

Results

In a random-effects IVW analysis, we found that genetic susceptibility to chronic hepatitis B was associated with an increased risk of atherosclerosis [OR = 1.048, 95% CI (1.022-1.075), P = 3.08E-04], as well as an increased risk of coronary heart disease [OR = 1.039, 95% CI (1.006-1.072), P = 0.020]. However, it was found to be inversely correlated with ischemic stroke risk [OR = 0.972, 95% CI (0.957-0.988), P = 4.13E-04]. There was no evidence that chronic hepatitis B was associated with hypertension [OR = 1.021, 95% CI (0.994-1.049), P = 0.121].

Conclusion

Our research indicates that chronic hepatitis B has a correlation with an elevated risk of developing atherosclerosis and coronary heart disease, while it is associated with a decreased risk of experiencing an ischemic stroke.

A systematic analysis on global epidemiology and burden of foot fracture over three decades

PURPOSE

To comprehensively analyze the geographic and temporal trends of foot fracture, understand its health burden by age, sex, and sociodemographic index (SDI), and explore its leading causes from 1990 to 2019.

METHODS

The datasets in the present study were generated from the Global Burden of Diseases Study 2019, which included foot fracture data from 1990 to 2019. We extracted estimates along with the 95% uncertainty interval (UI) for the incidence and years lived with disability (YLDs) of foot fracture by location, age, gender, and cause. The epidemiology and burden of foot fracture at the global, regional, and national level was exhibited. Next, we presented the age and sex patterns of foot fracture. The leading cause of foot fracture was another focus of this study from the viewpoint of age, sex, and location. Then, Pearson's correlations between age-standardized rate (ASR), SDI, and estimated annual percentage change were calculated.

RESULTS

The age-standardized incidence rate was 138.68 (95% UI: 104.88 - 182.53) per 100,000 persons for both sexes, 174.24 (95% UI: 134.35 - 222.49) per 100,000 persons for males, and 102.19 (95% UI: 73.28 - 138.00) per 100,000 persons for females in 2019. The age-standardized YLDs rate was 5.91 (95% UI: 3.58 - 9.25) per 100,000 persons for both genders, 7.35 (95% UI: 4.45 - 11.50) per 100,000 persons for males, and 4.51 (95% UI: 2.75 - 7.03) per 100,000 persons for females in 2019. The global incidence and YLDs of foot fracture increased in number and decreased in ASR from 1990 to 2019. The global geographical distribution of foot fracture is uneven. The incidence rate for males peaked at the age group of 20 - 24 years, while that for females increased with advancing age. The incidence rate of older people was rising, as younger age incidence rate declined from 1990 to 2019. Falls, exposure to mechanical forces, and road traffic injuries were the 3 leading causes of foot fracture. Correlations were observed between ASR, estimated annual percentage change, and SDI.

CONCLUSIONS

The burden of foot fracture remains high globally, and it poses an enormous public health challenge, with population ageing. It is necessary to allocate more resources to the high-risk populations. Targeted realistic intervention policies and strategies are warranted.

Teen Pregnancy and Risk of Premature Mortality

Importance

Unintentional injury, suicide, and homicide are leading causes of death among young females. Teen pregnancy may be a marker of adverse life experiences.

Objective

To evaluate the risk of premature mortality from 12 years of age onward in association with number of teen pregnancies and age at pregnancy.

Design, Setting, and Participants

This population-based cohort study was conducted among all females alive at 12 years of age from April 1, 1991, to March 31, 2021, in Ontario, Canada (the most populous province, which has universal health care and data collection). The study period ended March 31, 2022.

Exposures

The main exposure was number of teen pregnancies between 12 and 19 years of age (0, 1, or ≥2). Secondary exposures included how the teen pregnancy ended (birth or miscarriage vs induced abortion) and age at first teen pregnancy.

Main Outcomes and Measures

The main outcome was all-cause mortality starting at 12 years of age. Hazard ratios (HRs) were adjusted for year of birth, comorbidities at 9 to 11 years of age, and area-level education, income level, and rurality.

Results

Of 2 242 929 teenagers, 163 124 (7.3%) experienced a pregnancy at a median age of 18 years (IQR, 17-19 years). Of those with a teen pregnancy, 60 037 (36.8%) ended in a birth (of which 59 485 [99.1%] were live births), and 106 135 (65.1%) ended in induced abortion. The median age at the end of follow-up was 25 years (IQR, 18-32 years) for those without a teen pregnancy and 31 years (IQR, 25-36 years) for those with a teen pregnancy. There were 6030 deaths (1.9 per 10 000 person-years [95% CI, 1.9-2.0 per 10 000 person-years]) among those without a teen pregnancy, 701 deaths (4.1 per 10 000 person-years [95% CI, 3.8-4.5 per 10 000 person-years]) among those with 1 teen pregnancy, and 345 deaths (6.1 per 10 000 person-years [95% CI, 5.5-6.8 per 10 000 person-years]) among those with 2 or more teen pregnancies; adjusted HRs (AHRs) were 1.51 (95% CI, 1.39-1.63) for those with 1 pregnancy and 2.14 (95% CI, 1.92-2.39) for those with 2 or more pregnancies. Comparing those with vs without a teen pregnancy, the AHR for premature death was 1.25 (95% CI, 1.12-1.40) from noninjury, 2.06 (95% CI, 1.75-2.43) from unintentional injury, and 2.02 (95% CI, 1.54-2.65) from intentional injury.

Conclusions and Relevance

In this population-based cohort study of 2.2 million female teenagers, teen pregnancy was associated with future premature mortality. It should be assessed whether supports for female teenagers who experience a pregnancy can enhance the prevention of subsequent premature mortality in young and middle adulthood.

International Perspective on Extremity Vascular Trauma in Children: A Scoping Review

OBJECTIVE

Extremity vascular trauma in children can result in significant morbidity and mortality. Most published studies have focused on supracondylar humeral fracture related injuries, with little focus on other injuries. This scoping review describes the current state of knowledge on paediatric vascular injuries in the upper and lower limbs, excluding injuries related to supracondylar humeral fractures.

METHODS

MEDLINE, PubMed, Web of Science, and Cochrane databases were searched for relevant studies evaluating the epidemiology, diagnosis, management, and outcomes of upper and lower limb vascular trauma in those aged under 18 years. Studies related to supracondylar humeral fractures were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews was used.

RESULTS

A total of 39 studies was included, all of which were retrospective, and 74% of which were based in North America or Europe. Extremity vascular trauma was reported to cause 0.6 - 4.4% of all paediatric trauma admissions, with penetrating mechanisms and upper limb injuries being the most common. Operative intervention was reported in 80 - 100% of children in the included studies. Primary repair was the most commonly reported operative intervention, followed by interposition graft and bypass graft. Synthetic graft use was less commonly reported (incidence range 0.5 - 33%). Lower limb fasciotomies and amputations were not commonly reported (incidence range 0 - 23% and 0 - 13%, respectively). The mortality rate appeared low, with 23 studies reporting no deaths (incidence range 0 - 4%). Complications were reported inconsistently, with no uniform outcome or follow up measures used.

CONCLUSION

The incidence of extremity vascular trauma appears low in children, with penetrating mechanisms and upper extremity injuries appearing to dominate. Most studies are from high income countries, with probable selection bias towards those treated by operative intervention. Prospective studies are required focusing on patterns of injury, rates of operative and endovascular intervention, and long term outcomes.

Efficacy and safety of non-invasive brain stimulation in combination with antidepressants in adolescents with depression: a systematic review and meta-analysis

Objective

Non-invasive brain stimulation (NIBS) is beneficial to adult patients with depression, but its safety and efficacy in combination with antidepressants in children and adolescents with depression are not clear. We conducted a preliminary meta-analysis to objectively evaluate its clinical effect and provide information for future research and clinical practice.

Methods

PubMed, Cochrane Library, Embase, and Web of Science were searched systematically to find clinical trials published in English before April 11, 2023. Stata software was used for meta-analysis, and random or fixed effect models were used to combine effect sizes.

Results

Nine studies were eligible and included (n = 393). No articles about children were included in the analysis. The results showed that the remission rate was 40% (95% confidence interval [CI]: 13% to 71%). The scores of Children's Depression Rating Scale (CRDS) and Hamilton's depression scale (HAMD) significantly decreased compared to baseline value (MD = -27.04, 95% CI: -30.95, -23.12 and MD = -12.78, 95% CI: -19.55 to -6.01). In addition, the incidence of all adverse events was 13% (95% CI: 5%, 23%), and all were minor pain-related events.

Conclusion

The combination of NIBS and antidepressants has been shown to notably alleviate depressive symptoms in adolescents, offering a considerable level of safety. This therapeutic synergy is particularly effective in patients with major depressive disorder, where repetitive transcranial magnetic stimulation augmented with antidepressants can enhance the amelioration of depressive symptoms.

Global burden of all cause-specific injuries among children and adolescents from 1990 to 2019 : a prospective cohort study

BACKGROUND

To assess the burden and change in incidence, death, and disability-adjusted life years (DALYs) for all-cause-specific injuries among children and adolescents in 204 countries and territories between 1990 and 2019.

MATERIALS AND METHODS

Data were extracted from the Global Burden of Disease, Injury, and Risk Factor Study 2019 (GBD 2019). Global, regional, and country-level age-standardized rate (per 100,000) of incidence (ASRI), mortality (ASRM), and DALYs (ASRD) with 95% uncertainty interval (95% UI) of injuries were estimated by age, sex, socio-demographic index (SDI), and all-cause specific injuries from 1990 to 2019.

RESULTS

Overall, the ASRI, ASRM, and ASRD of injury were 9006.18 (95%UI: 7459.74 to 10918.04), 23.04 (20.00 to 26.50), and 2020.19 (1759.47 to 2318.64) among children and adolescents worldwide in 2019, respectively. All the above indicators showed a downward trend from 1990 to 2019. In level 2 cause of injury, both the global transport injury and unintentional injury declined during the study years, while self-harm and interpersonal violence-related injury showed an increasing trend. High SDI regions had higher ASRI of injuries, but low SDI regions had higher ASRM and ASRD of injuries globally in 2019. Males had a higher burden of injuries than those in females. The ASRI of injuries is higher in adolescents aged 15-19 years, whereas the mortality and DALYs rate are higher among children under 5 years old. Moreover, adolescents aged 15-19 years and individuals living in Central Asia, Middle East, and Africa had higher ASRI, ASRM, and ASRD of injuries owing to self-harm and interpersonal violence. Generally, falls and road traffic injuries are the leading cause of injury among the population aged 0-19 years worldwide, but self-harm, interpersonal violence, and conflict and terrorism are also leading types of injuries in some regions, particularly in Low- and Middle-Income Countries.

CONCLUSIONS

Injury remains a major global public health problem among children and adolescents, although its burden at the worldwide level showed a decreasing trend from 1990 to 2019. Of concern, the burden of injuries caused by transport injuries, and unintentional injuries has shown a downward trend in most countries, while the burden caused by self-harm and interpersonal violence has shown an upward trend in most countries. These findings suggest that more targeted and specific strategies to prevent the burden of injuries should be reoriented, and our study provides important findings for decision-makers and healthcare providers to reduce injury burden among children and adolescents.

Prevalence and correlates of unintentional nonfatal injuries among school-going adolescents in Central America

OBJECTIVES

The aim of this study is to report on the frequency of serious physical injuries (SPI) among adolescents in Central America during the previous decade, 2009-2018.

METHODS

In total, 15,807 school adolescents (14.4 years mean age; SD=1.4) from six Central American countries participated in cross-sectional Global School-based Student Health Surveys in 2009-2018 (ranging from 1,779 students in Honduras in 2012 to 4,374 students in Guatemala in 2015).

RESULTS

The prevalence of SPI was 33.8 % (22.9 % once, 7.4 % 2 or 3 times and 3.6 % 4 or more times), ranging from 31.8 % in Guatemala to 45.0 % in Belize and 45.6 % in Panama. The most frequent causes of SPI included fall (11.4 %, ranging from 6.9 % in Costa Rica to 15.6 % in Panama), and the type of SPI was fracture/dislocation (5.7 %, ranging from 4.3 % in Costa Rica to 6.7 % in Panama). In adjusted Poisson regression, male sex, food insecurity, a history of alcohol intoxication, soft drink consumption, fast food intake, truancy, multiple sexual partners, psychological distress, physical fight, physically attacked, bullied, and suicide attempt were significantly associated with a higher number of injury event counts.

CONCLUSIONS

Overall, about one in three adolescents in Central America had sustained unintentional injuries in the past 12 months and several contributing factors were identified which if addressed could aid injury prevention among adolescents.

Interpersonal Violence and Gender Inequality in Adolescents: A Systematic Analysis of Global Burden of Disease Data From 1990 to 2019

PURPOSE

Interpersonal violence is a leading cause of adolescent deaths and disability. This study investigates sex differences in burden of interpersonal violence for adolescents and explores associations with gender inequality.

METHOD

Using data from the 2019 Global Burden of Disease study, we report numbers, proportions, rates of interpersonal violence deaths and disability adjusted life years (DALYs) for all ages, and rate of change (from 1990 to 2019) in adolescents aged 10-24 years disaggregated by sex and geography. We explored associations with gender inequality using gender inequality index.

RESULTS

One in four (24.8%) all-age interpersonal violence deaths are in adolescents. In 2019, the rate of deaths in adolescent males was almost six times higher than females (9.3 vs. 1.6 per 100,000); and since 1990, the rate of decline in DALYs for females was double than that for males (-28.9% vs. -12.7%). By contrast, the burden of sexual violence is disproportionately borne by adolescent females, with over double the rate than males (DALYs: 42.8 vs. 17.5 per 100,000). In countries with greater gender inequality, the male-to-female ratio (deaths and DALYs) was increased among older adolescents, pointing to benefits for males in more gender equal settings.

DISCUSSION

Social identities, relationships, and attitudes to violence are established in adolescence, which is an inflection point marking the emergence of disproportionate burdens of interpersonal violence. Our findings affirm that global agendas must be expanded to address interrelated factors driving multiple forms of interpersonal violence experienced by adolescents and reverberating to the next generation.

Global, regional, and national burden of depressive disorders among young people aged 10-24 years, 2010-2019

OBJECTIVE

To describe the latest disease burden, temporal trends, and risk factors of depressive disorders among young people.

METHODS

Data from the Global Burden of Disease Study 2019 was utilized to analyze depressive disorders among individuals aged 10-24 years. The study focused on describing the incidence, prevalence, disability-adjusted life years (DALYs), and their attributable risk factors across 204 countries and territories from 2010 to 2019. The estimated annual percentage change (EAPC) was calculated to quantify the temporal trends.

RESULTS

Globally, the incidence, prevalence, and DALYs rate of depressive disorders per 100 000 young people increased from 3003.01, 2445.69, and 448.61 in 2010 to 3035.26, 2470.67, and 452.58 in 2019, indicating a slight upward trend (EAPC = 0.11 for incidence and prevalence; EAPC = 0.09 for DALYs rate). Notably, the percentage of DALYs of depressive disorders among young people increased substantially from 3.24% in 2010 to 3.66% in 2019, an increase of 13.06% (EAPC = 1.26, 95%CI: 1.08-1.44), and the burden of depressive disorders among young people rose from fouth to second in females, and from tenth to fifth in males. Social demographic index (SDI) and other indicators were positively correlated with the percentage of DALYs of depressive disorder and negatively correlated with the EAPC of DALYs.

CONCLUSION

The global burden of depressive disorders among young people is on the rise. The regional differences in depressive disorders among young people suggest the need for enhanced screening efforts in low-SDI areas, along with the adoption of more effective prevention and control measures.

Age-period-cohort analysis of incidence, mortality and disability-adjusted life years of esophageal cancer in global, regional and national regions from 1990 to 2019

OBJECTIVE

In view of the high incidence and mortality of esophageal cancer, the latest statistical data on the disease burden of esophageal cancer can provide strategies for cancer screening, early detection and treatment, and help to rationally allocate health resources. This study provides an analysis of the global disease burden and risk factors of esophageal cancer from 1990 to 2019.

METHODS

Using the 2019 Global Burden of Disease, Injury and Risk Factor (GBD) data, we present the incidence, mortality and disability-adjusted life years (DALY) of esophageal cancer in 21 regions and 204 countries and different sociodemographic index (SDI) regions from 1990 to 2019. The age-period-cohort model was used to estimate the age, period, and cohort trend of esophageal cancer in different SDI regions. The estimated proportion of DALY attributable to each risk factor from 1990 to 2019.

RESULTS

From 1990 to 2019, the number of new cases of esophageal cancer, the number of deaths and DALY increased by 67.07%, 55.97% and 42.13%, respectively, but age standardized incidence rate (ASIR), age standardized mortality rate (ASMR) and age standardized DALY rate (ASDR) decreased by 19.28%, 25.32% and 88.22%, respectively. Overall, the results of the age-period-cohort model showed that the incidence, mortality, and DALY rates in countries and regions with higher SDI levels showed a downward trend over time and with the passage of time. Conversely, there were no significant changes in incidence and mortality in countries and regions with low SDI levels. In the past 30 years, the incidence and death of esophageal cancer in the world has gradually changed to people over 80 years old, but the population aged 60-79 still accounts for the largest proportion. The global DALY in esophageal cancer is mainly attributable to smoking, followed by alcohol consumption and occupational exposure.

CONCLUSIONS

Although ASIR, ASMR and ASDR have decreased significantly, esophageal cancer is still the main factor causing the disease burden worldwide. Public health administrators in low SDI and low-middle SDI countries are high-risk areas for esophageal cancer, and preventive control measures should be implemented to raise awareness, screening, and treatment of esophageal cancer in these areas. Tobacco and alcohol control and reduction of occupational hazards are key steps in reducing the burden of esophageal cancer.

Review of the India Adolescent Health Strategy in the context of disease burden among adolescents

Background

A nuanced understanding of the health needs of adolescents in the context of the India Adolescent Health Strategy (IAHS) is needed to inform policy interventions for improving the health and well-being of adolescents in India.

Methods

Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, we identified the top ten causes of years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) disaggregated by sex and age group (10-14 and 15-19 years) for India and its states in 2019. To inform the IAHS of refinement or expansion in focus needed to improve adolescent health in India, we reviewed the extent to which the top 10 causes of disease burden are addressed in the IAHS, and the availability of and age- and sex-disaggregation in the service utilisation data for adolescents captured in the Adolescent Friendly Health Clinic monitoring information system (AFHC MIS) and Health Management Information System (HMIS). We also reviewed the availability of and age-and sex-disaggregation in the data capture at the population level for the IAHS outcome indicators in the data sources identified in the IAHS operational framework.

Findings

Females in the 10-14 and 15-19 years age groups suffered 6.75 million and 9.25 million DALYs, respectively, 39.1% and 44.2% of which were YLLs; the corresponding DALYs for males were 6.71 million and 9.65 million (42.3% and 41.1% YLLs), respectively. Within the 6 thematic areas of the IAHS, most strategies and indicators identified are for sexual and reproductive health followed by nutrition, and broadly these conditions accounted for YLDs and not YLLs in adolescents. Significant gaps in the IAHS in comparison to the disease burden for fatal diseases and conditions were seen across injuries, communicable diseases, and non-communicable diseases. Injuries accounted for 65.9% and 45.3% of YLLs in males and females aged 15-19 years, and 40.8% in males aged 10-14 years. Specifically, road injuries (15.3%, 95% UI 11.0-18.0) and self-harm (11.3%, 95% UI 8.7-14.2) accounted for most of the injury deaths in 15-19 years whereas drowning (7.7% 95% UI 5.8-9.6) and road injuries (6.9%, 95% UI 4.7-8.6) accounted for the most injury deaths in 10-14 years males. However, only self-harm and gender-based violence are specifically addressed in the IAHS with non-specific interventions for other injuries. Diarrhoea, lower respiratory infections, malaria, encephalitis, tuberculosis, typhoid, cirrhosis, and hepatitis are the other disease conditions accounting for YLLs and DALYs in adolescents but these are neither addressed in the IAHS nor in service provision under the AFHC MIS. There is no age- or sex-disaggregation in the cause of death data captured in the HMIS to allow an understanding of mortality in adolescents. For the IAHS outcome indicators at the population level, data capture for the 10-14 years irrespective of sex was largely missing from the population surveys and none of the surveys captured data for either females or males aged 15-19 years for physical inactivity and mental health indicators.

Interpretation

The considerable differences seen in the IAHS thematic focus as compared with the leading causes of fatal and non-fatal disease burden in adolescents in India, and in the availability of population-level data to monitor the outcome indicators of the IAHS can pose substantial limitations for improving adolescent health in India. The findings in this paper can be utilized by decision makers to refine action aimed at improving adolescent health and well-being.

Global prevalence of cardiovascular diseases by gender and age during 2010-2019

Introduction

The aim of this study was to evaluate the global, gender, and age-related cardiovascular disease (CVD) burden during 2010-2019. Not only the global trend in the prevalence of CVDs was studied but also whether there was a statistically significant difference between genders and ages during 2010-2019.

Material and methods

Detailed information from 2010 to 2019, including global rates of prevalence of 11 categories of CVD, was collected from the Global Burden of Disease Study 2019. The statistical methods used to analyze the results of this study are the independent samples t-test and one-way analysis of variance (ANOVA) test.

Results

The global prevalence rate of CVDs increased from 0.061% in 2010 to 0.070% in 2019. There was a statistically significant difference in prevalence rates between genders in all cardiovascular diseases except atrial fibrillation and flutter. Females have higher prevalence rates of CVDs worldwide. Moreover, females have statistically significantly higher prevalence rates of stroke, hypertensive heart disease, rheumatic heart disease, non-rheumatic valvular heart disease, endocarditis, peripheral artery disease and other cardiovascular and circulatory diseases globally. On the other hand, males have statistically significantly higher prevalence rates of cardiomyopathy and myocarditis, and ischemic heart disease globally. Rheumatic heart disease has a statistically significantly higher prevalence rate in the age group of 25-49 years than the other age groups.

Conclusions

The significance of this study is not only that it has succeeded in evaluating the global, gender, and age-related cardiovascular disease (CVD) burden, finding statistically significant associations, but it is also the only study to achieve this goal in the last decade.

Spatial distribution and determinants of barriers of health care access among female youths in Ethiopia, a mixed effect and spatial analysis

Access to healthcare services is a fundamental human right for every citizen, and it is the responsibility of the nation to guarantee that these services are acceptable, easily accessible, and timely. Barriers to accessing health services may have a detrimental effect on an individual's physical, and mental health, and overall quality of life. However, access to health care services is a common problem in developing countries. Therefore, this study aimed to investigate spatial distribution and determinants of barriers to healthcare access among female youths in Ethiopia. Secondary data analysis was conducted based on the Demographic and Health Surveys data conducted in Ethiopia. A total weighted sample of 6143 female youths aged 15-24 years old was included in this study. A mixed-effect analysis was employed to identify factors contributing to barriers to healthcare access among youths in Ethiopia. Adjusted Odds Ratio with 95% CI was used to declare the strength and significance of the association. The concentration index was used to assess wealth-related inequalities, while spatial analysis was used to explore the spatial distribution and significant windows of barriers to healthcare access. This study revealed that the magnitude of barriers to healthcare access among female youth was 61.3% with 95%CI (60.1 to 62.5) to at least one or more of the four reasons. Age 15-19 years old (AOR = 0.80, 95%CI 0.68 to 0.95), no formal education (AOR = 2.26, CI 1.61, 3.18), primary education (AOR = 2.21, CI 1.66, 2.95), marital status (AOR = 1.43, 95% CI 1.21, 1.70), poor household wealth (AOR = 1.63, 95% CI 1.31, 2.05), no Media exposure (AOR = 1.67, 95%CI 1.41-1.98), reside in rural areas (AOR = 1.63, 95%CI 1.05 to 2.54), and low community media exposure (AOR = 1.45, 95%CI 1.01-2.08) were significantly associated with barriers of health care service. Barriers to healthcare access were significantly and disproportionately concentrated in poor households. A non-random Barrier to healthcare access was observed in Ethiopia. Among the 9 regions, primary clusters were identified in only 4 regions (North Ormiya, Benishangul Gumuz, Gambella, and South Nation Nationality and Peoples regions. A significant proportion of female youths faced barriers to health care access Age, educational status, marital status, rural residency, low economic status, and media exposure were factors associated with barriers to health care access. Therefore, program planners and decision-makers should work on improving the country's economy to a higher economic level to improve the wealth status of the population, promote media exposure, and increase access to education.

The Molecular Mechanisms Involved in the Hypertrophic Scars Post-Burn Injury

Scar formation is a normal response to skin injuries. During the scar-remodeling phase, scar tissue is usually replaced with normal, functional tissue. However, after deep burn injuries, the scar tissue may persist and lead to contractures around joints, a condition known as hypertrophic scar tissue. Unfortunately, current treatment options for hypertrophic scars, such as surgery and pressure garments, often fail to prevent their reappearance. One of the primary challenges in treating hypertrophic scars is a lack of knowledge about the molecular mechanisms underlying their formation. In this review, we critically analyze studies that have attempted to uncover the molecular mechanisms behind hypertrophic scar formation after severe burn injuries, as well as clinical trials conducted to treat post-burn hypertrophic scars. We found that most clinical trials used pressure garments, laser treatments, steroids, and proliferative inhibitors for hypertrophic scars, with outcomes measured using subjective scar scales. However, fundamental research using human burn injury biopsies has shown that pathways such as Transforming Growth factor β (TGFβ), Phosphatase and tensin homolog (PTEN), and Toll-like receptors (TLRs) could be potentially regulated to reduce scarring. Therefore, we conclude that more testing is necessary to determine the efficacy of these molecular targets in reducing hypertrophic scarring. Specifically, double-blinded clinical trials are needed, where the outcomes can be measured with more robust quantitative molecular parameters.

Global disease burden and its attributable risk factors of peripheral arterial disease

Peripheral arterial disease (PAD) is a prevalent subtype of atherosclerotic cardiovascular diseases. It is crucial to assess the PAD-related burden and its attributable risk factors. We use the Global Burden of Disease study 2019 database to calculate the incidence, prevalence, mortality, disability-adjusted life years (DALY), attributable risk factors and estimated annual percentage change. The disease burden of PAD grows significantly with age accompanied by prominent heterogeneity between male and female. Despite the increase in the absolute numbers of disease burden from 1990 to 2019, the global PAD-related age-standardized death rate (ASDR) and age-standardized disability-adjusted life years rate (ASDALYR) have a mild downward trend from 1990 to 2019, which negatively correlated with sociodemographic index (SDI). Smoking and high systolic blood pressure (SBP) were the primary attributable risk factors for males (ASDR: 33.4%; ASDALYR: 43.4%) and females (ASDR: 25.3%; ASDALYR: 27.6%), respectively. High fasting plasma glucose (FPG) had become the second risk factor for ASDR (males: 28.5%; females: 25.2%) and ASDALYR (males: 29.3%; females: 26.3%) with an upward tendency. Low-middle SDI regions were predicted to have the most remarkable upward trend of PAD-related burden caused by high FPG. Smoking caused more disease burden in males before 85-90 years old and females before 65-70 years old, while high FPG and high SBP caused more burden after that. The patterns of PAD-related burden and its attributable risk factors are heterogeneous across ages, genders, and SDI regions. To reduce disease burden, tailored strategies should be implemented.

University students' intentions to seek psychological counseling, attitudes toward seeking psychological help, and stigma

BACKGROUND

Mental health problems are prevalent among university students worldwide. Studies have shown that most students do not disclose and do not get the psychological help and support they need.

OBJECTIVES

This survey aims to investigate the intentions to seek psychological counseling (ISC) among university students, their attitudes toward seeking professional psychological help (ATSPPH), and the predictors of those intentions and attitudes including stigma.

DESIGN AND METHODS

a cross-sectional survey was conducted among 420 students at the American University of Beirut (AUB).

RESULTS

Depression, test anxiety, and difficulty sleeping are the three main reasons students would seek psychological help. The source the students most preferred to ask for help was one's family followed by psychologists and psychiatrists. Students' ATSPPH is a positive predictor of their ISC, while students' self-stigma of seeking help (SSOSH) is a negative predictor of their ATSPPH. Moreover, students' awareness of the psychological help system available on campus, free of charge, is a positive predictor for both ISC and ATSPPH.

CONCLUSION

Different interventions are needed to reduce stigma and enhance students' mental health literacy and awareness of the available professional psychological help on campus.

Adolescent's anhedonia and association with childhood trauma among Chinese adolescents: a cross-sectional study

OBJECTIVES

To estimate the level of anhedonia among adolescents and explore the association between anhedonia and childhood trauma (CT).

DESIGN

A stratified random cluster sample of adolescents participated in a survey, which included three questionnaires: Snaith-Pamilton Pleasure Scale, Childhood Trauma Questionnaire and Patient Health Questionnaire-9.

SETTING

The study was conducted in 60 classes in 10 primary, middle and high schools in five economically developed cities along the Southeast Coast of China from April to October 2022.

PARTICIPANTS

One thousand seven hundred and forty-five adolescents with ages ranging from 9 to 18 years participated in the study.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome was the level of anhedonia, CT and depression among adolescents. The association between anhedonia and CT was determined.

RESULTS

The mean scores of anhedonia, CT and depression were 24.88 (6.18), 36.75 (8.87) and 4.46 (5.36), respectively. Anhedonia scores of boys (24.24±6.12) and girls (25.62±6.16) were different (t=-4.69, p<0.01). After controlling for sex, age, the presence of siblings and depression, CT was associated with adolescent anhedonia. Emotional abuse (β=0.14), emotional neglect (β=0.15) and physical neglect (β=0.10) positively predicted adolescent anhedonia (p<0.01), whereas physical abuse negatively predicted adolescent anhedonia (β=-0.07, p<0.01). Sex had a moderating effect on the relationship between adolescent anhedonia and emotional neglect during childhood, and the negative effect of emotional neglect on adolescent anhedonia in girls was greater than in boys.

CONCLUSIONS

CT, including emotional abuse, physical abuse, emotional neglect, and physical neglect, was an independent predictor of adolescents' ability to experience pleasure in daily life. Therefore, awareness of CT should be promoted. Emotional neglect had a more severe effect on anhedonia among girls than among boys, suggesting that emotional neglect should be paid much attention among girls.

Antimicrobial drug resistant features of Mycobacterium tuberculosis associated with treatment failure

Tuberculosis stands as a prominent cause of mortality in developing countries. The treatment of tuberculosis involves a complex procedure requiring the administration of a panel of at least four antimicrobial drugs for the duration of six months. The occurrence of treatment failure after the completion of a standard treatment course presents a serious medical problem. The purpose of this study was to evaluate antimicrobial drug resistant features of Mycobacterium tuberculosis associated with treatment failure. Additionally, it aimed to evaluate the effectiveness of second line drugs such as amikacin, linezolid, moxifloxacin, and the efflux pump inhibitor verapamil against M. tuberculosis isolates associated with treatment failure. We monitored 1200 tuberculosis patients who visited TB centres in Lahore and found that 64 of them were not cured after six months of treatment. Among the M. tuberculosis isolates recovered from the sputum of these 64 patients, 46 (71.9%) isolates were simultaneously resistant to rifampicin and isoniazid (MDR), and 30 (46.9%) isolates were resistant to pyrazinamide, Resistance to amikacin was detected in 17 (26,5%) isolates whereas resistance to moxifloxacin and linezolid was detected in 1 (1.5%) and 2 (3.1%) isolates respectively. Among MDR isolates, the additional resistance to pyrazinamide, amikacin, and linezolid was detected in 15(23.4%), 4(2.6%) and 1(1.56%) isolates respectively. One isolate simultaneously resistant to rifampicin, isoniazid, amikacin, pyrazinamide, and linezolid was also identified. In our investigations, the most frequently mutated amino acid in the treatment failure group was Serine 315 in katG. Three novel mutations were detected at codons 99, 149 and 154 in pncA which were associated with pyrazinamide resistance. The effect of verapamil on the minimum inhibitory concentration of isoniazid and rifampicin was observed in drug susceptible isolates but not in drug resistant isolates. Rifampicin and isoniazid enhanced the transcription of the efflux pump gene rv1258 in drug susceptible isolates collected from the treatment failure patients. Our findings emphasize a high prevalence of MDR isolates linked primarily to drug exposure. Moreover, the use of amikacin as a second line drug may not be the most suitable choice in such cases.

Sex differences in mortality among children, adolescents, and young people aged 0-24 years: a systematic assessment of national, regional, and global trends from 1990 to 2021

BACKGROUND

Differences in mortality exist between sexes because of biological, genetic, and social factors. Sex differentials are well documented in children younger than 5 years but have not been systematically examined for ages 5-24 years. We aimed to estimate the sex ratio of mortality from birth to age 24 years and reconstruct trends in sex-specific mortality between 1990 and 2021 for 200 countries, major regions, and the world.

METHODS

We compiled comprehensive databases on the mortality sex ratio (ratio of male to female mortality rates) for individuals aged 0-4 years, 5-14 years, and 15-24 years. The databases contain mortality rates from death registration systems, full birth and sibling histories from surveys, and reports on household deaths in censuses. We modelled the sex ratio of age-specific mortality as a function of the mortality in both sexes using Bayesian hierarchical time-series models. We report the levels and trends of sex ratios and estimate the expected female mortality and excess female mortality rates (the difference between the estimated female mortality and the expected female mortality) to identify countries with outlying sex ratios.

FINDINGS

Globally, the mortality sex ratio was 1·13 (ie, boys were more likely to die than girls of the same age) for ages 0-4 years (90% uncertainty interval 1·11 to 1·15) in 2021. This ratio increased with age to 1·16 (1·12 to 1·20) for 5-14 years, reaching 1·65 for 15-24 years (1·52 to 1·75). In all age groups, the global sex ratio of mortality increased between 1990 and 2021, driven by faster declines in female mortality. In 2021, the probability of a newborn male reaching age 25 years was 94·1% (93·7 to 94·4), compared with 95·1% for a newborn female (94·7 to 95·3). We found a disadvantage of females versus males (compared with countries with similar total mortality) in 2021 in five countries for ages 0-4 years (Algeria, Bangladesh, Egypt, India, and Iran), one country (Suriname) for ages 5-14 years, and 13 countries for ages 15-24 years (including Bangladesh and India). We found the reverse pattern (disadvantage of males vs females compared with countries of similar total mortality) in one country in ages 0-4 years (Vietnam) and eight countries in ages 15-24 years (including Brazil and Mexico). Globally, the number of excess female deaths from birth to age 24 years was 86 563 (-6059 to 164 000) in 2021, down from 544 636 (453 982 to 633 265) in 1990.

INTERPRETATION

The global sex ratio of mortality for all age groups in the first 25 years of life increased between 1990 and 2021. Targeted interventions should focus on countries with outlying sex ratios of mortality to reduce disparities due to discrimination in health care, nutrition, and violence.

Associations between alcohol intake and hospital contacts due to alcohol and unintentional injuries in 71,025 Danish adolescents - a prospective cohort study

Background

Alcohol is a leading risk factor to adolescent health. However, it is unclear how associations between alcohol intake and injuries are shaped. We investigated the dose-response relationship between alcohol intake and risk of hospital contacts due to alcohol and unintentional injuries in adolescents.

Methods

We conducted a prospective cohort study including 71,025 Danish students aged 15-24 years, followed up for five years from 2014 to 2019. The main outcome measures were hospital contacts due to alcohol and unintentional injuries (all injuries and head injuries), obtained from hospital registers.

Findings

Approximately 90% of males and females reported drinking alcohol, and the median intake among those was 11 drinks/week in males and 8 drinks/week in females. During five years of follow-up, 1.3% had an alcohol-attributable hospital contact, the majority of which were due to acute intoxication (70%). Alcohol-attributable hospital contacts were equally frequent in males and females and between age groups (15-17-year-olds vs 18-24-year-olds). Compared with never drinking, the adjusted incidence rate ratios for weekly intake of <7, 7-13, 14-20, 21-27, and >27 drinks/week were 1.70 (95% confidence interval 1.23-2.34), 1.77 (1.27-2.46), 1.91 (1.35-2.70), 2.34 (1.59-3.46), and 3.25 (2.27-4.64) for having an alcohol-attributable hospital contact within five years of follow-up. Restricting follow-up to one year more than doubled risk estimates. During the five years of follow-up, 27% incurred an unintentional injury. The most frequent types of injury were to the wrist or hand (27.6%), ankle or foot (25.2%), or head (12.4%). Injuries were more frequent among males (first-time incidence rate 110 per 1000 person-years) compared to females (82 per 1000 person-years), with no differences between age groups. Compared with never drinking, the adjusted incidence rate ratios for weekly intake of <7, 7-13, 14-20, 21-27, and >27 drinks were 1.09 (1.03-1.15), 1.14 (1.07-1.20), 1.25 (1.17-1.33), 1.38 (1.28-1.49), and 1.58 (1.47-1.69) for having a hospital contact for any type of unintentional injury within five years of follow-up. Results for the one-year follow-up period were comparable. Separate analysis for head injuries showed similar results as the analysis on all injuries. Results were generally similar in males and females.

Interpretation

Adolescents' drinking is associated with a higher risk of acute harm in terms of hospital contacts due to alcohol and unintentional injuries in a dose-response relationship. Thus, increased risk was apparent in those with low alcohol intake, suggesting a need for awareness of and initiatives to prevent youth drinking. Furthermore, initiatives should include a strengthened focus on people younger than 18 years.

Unmasking the Underlying Causes: A Cross-Sectional Analysis of Mortality From Intentional and Unintentional Injuries in the United Arab Emirates

The United Arab Emirates (UAE) has experienced substantial development in infrastructure and transportation in the last few decades. Although available evidence suggests that the incidence of injuries has considerably increased in the previous few years, there is a scarcity of literature that comprehensively analyzed the mortality due to different types of injuries in the UAE. Therefore, the current study was designed to report mortality due to various intentional and unintentional injuries in the UAE. Secondary data was obtained from the World Health Organization (WHO) mortality database. We targeted injuries-specific mortality datasets. We applied a filter (UAE) to retrieve mortality data from unintentional and intentional injuries in the UAE. The latest data in the WHO mortality database was for 2020-21. A total of 10,357 death records from the UAE were present in the WHO mortality database. The percentage of injury-specific deaths out of total deaths was 8.69% (n=900). Injury-specific mortality rate per 100,000 population was 9.09. The percentage of injury-specific deaths was higher for males (87.3%, n=786) and the age group 25-34 years (n=323, 35.9%). Of the 900 injury-specific deaths, 449 (49.9%) were due to unintentional injuries, 216 (24.0%) were due to unintentional injuries, while the remaining (26.1%, n=235) deaths occurred due to Ill-defined injuries. More than half (53.7%, n=241) of unintentional injuries were because of road traffic injuries (RTIs) followed by fall (14.7%, n=66), exposure to mechanical forces (6.5%, n=29), drowning (6.0%, n=27) fire (1.1%, n=5), poisonings (1.1%, n=5), natural disasters (n=1, 0.2%) and other unintentional injuries (16.7%, n=75). More than three-quarters (83.3%, n=180) of intentional injuries were because of self-inflicted injuries while the remaining (16.7%, n=36) intentional injuries-specific deaths occurred due to violence. Many deaths in the UAE occur due to unintentional and intentional injuries. RTIs and falls are the leading causes of unintentional injury-specific deaths, while self-inflicted injuries and violence are the leading causes of intentional injury-specific deaths.

Global burden of neoplasms attributable to specific occupational carcinogens over 30 years: a population-based study

OBJECTIVES

The study aimed to analyze the global burden of occupational neoplasms from various epidemiological perspectives.

STUDY DESIGN

In this cross-sectional study, secondary analyses were conducted to assess the burden of neoplasms attributable to occupational carcinogens and their distribution characteristics using data from GBD 2019 and the World Bank database.

METHODS

Based on the GBD 2019 and the World Bank database, we analyzed the global burden of occupational neoplasms including the age-period-cohort model, decomposition analysis, health inequality analysis, and panel model. All analyses were conducted in R (version 4.0.3) and Joinpoint (version 4.9.1).

RESULTS

The absolute number of neoplasms burden attributable to occupational carcinogens has continued to rise over 30 years. In 2019, occupational neoplasms caused 333,867 [95% uncertainty interval (UI): 263,491 to 404,641] mortalities and 6,964,775 (95% UI: 5,467,884 to 8,580,431) disability-adjusted life years (DALYs) globally. Greenland, Monaco, the Netherlands, and Andorra suffered the highest burden. The burden was higher in countries with a higher sociodemographic index. The age effect was prominent in the elderly, and the 1925 birth cohort had the highest cohort effect. Population growth was the most significant driver of the mortalities (89%) and DALYs (111%) change. Moreover, the proportion of urban population was significantly positively associated with the disease burden, while GDP per capita was negatively correlated with the disease burden.

CONCLUSIONS

The burden of occupational neoplasms was unevenly distributed across locations and populations. The need for rational allocation of healthcare resources was urgent.

Epidemiological features and temporal trends of HIV-negative tuberculosis burden from 1990 to 2019: a retrospective analysis based on the Global Burden of Disease Study 2019

OBJECTIVE

This study aimed to analyse the burden and temporal trends of tuberculosis (TB) incidence and mortality globally, as well as the association between mortality-to-incidence ratio (MIR) and Socio-Demographic Index (SDI).

DESIGN

A retrospective analysis of TB data from 1990 to 2019 was conducted using the Global Burden of Disease Study database.

RESULTS

Between 1990 and 2019, there was a declining trend in the global incidence and mortality of TB. High SDI regions experienced a higher declining rate than in low SDI regions during the same period. Nearly half of the new patients occurred in South Asia. In addition, there is a sex-age imbalance in the overall burden of TB, with young males having higher incidence and mortality than females. In terms of the three subtypes of TB, drug-sensitive (DS)-TB accounted for more than 90% of the incidents and deaths and experienced a decline over the past 30 years. However, drug-resistant TB (multidrug-resistant (MDR)-TB and extensively drug-resistant (XDR)-TB) showed an overall increasing trend in age-standardised incidence rates and age-standardised mortality rates, with an inflection point after the year 2000. At the regional level, South Asia and Eastern Europe remained a high burden of drug-resistant TB incidence and mortality. Interestingly, a negative correlation was found between the MIR and SDI for TB, including DS-TB, MDR-TB and XDR-TB. Notably, central sub-Saharan Africa had the highest MIR, which indicated a higher-than-expected burden given its level of sociodemographic development.

CONCLUSION

This study provides comprehensive insights into the global burden and temporal trends of TB incidence and mortality, as well as the relationship between MIR and SDI. These findings contribute to our understanding of TB epidemiology and can inform public health strategies for prevention and management.

Identifying strategic priorities for advancing global drowning prevention: a Delphi method

INTRODUCTION

The burden of drowning is gaining prominence on the global agenda. Two United Nations system resolutions in 3 years reflect rising political support, but priorities remain undefined, and the issue lacks a global strategy. We aimed to identify strategic priorities for advancing global drowning prevention using a modified Delphi method.

METHODS

An advisory group was formed, and participants recruited with diverse expertise and backgrounds. We used document review, and data extracted from global health partnerships to identify strategic domains and draft priorities for global drowning prevention. Participants rated the priorities in two Delphi rounds, guided by relevance, feasibility and impact on equity, and where consensus was ≥70% of participants rating the priority as critical.

RESULTS

We recruited 134 participants from research (40.2%), policy (26.9%), technical (25.4%) and community (7.5%) backgrounds, with 38.1% representing low- and middle-income countries. We drafted 75 priorities. Following two Delphi rounds, 50 priorities were selected across the seven domains of research and further contextualisation, best practice guidance, capacity building, engagement with other health and sustainable development agendas, high-level political advocacy, multisectoral action and strengthening inclusive global governance. Participants scored priorities based on relevance (43.2%), feasibility (29.4%) and impact on equity (27.4%).

CONCLUSION

Our study identifies global priorities for drowning prevention and provides evidence for advocacy of drowning prevention in all pertinent policies, and in all relevant agendas. The priorities can be applied by funders to guide investment, by researchers to frame study questions, by policymakers to contrast views of expert groups and by national coalitions to anchor national drowning prevention plans. We identify agendas including disaster risk reduction, sustainable development, child and adolescent health, and climate resilience, where drowning prevention might offer co-benefits. Finally, our findings offer a strategic blueprint as the field looks to accelerate action, and develop a global strategy for drowning prevention.

Burden of non-communicable diseases among adolescents and young adults aged 10-24 years in the South-East Asia and Western Pacific regions, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Although non-communicable diseases (NCDs) remain the leading causes of mortality and disability worldwide, little comprehensive or recent evidence of the burden of NCDs among adolescents and young adults in the South-East Asia and Western Pacific regions is available. We aimed to report population shifts in people aged 10-24 years and their NCD burden from 1990 to 2019 using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019.

METHODS

We retrieved data from GBD 2019 for people aged 10-24 years in the South-East Asia and Western Pacific regions from 1990 to 2019. We presented population shifts and analysed deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) for NCDs. We also quantified the associations of deaths and DALYs with the Socio-demographic Index (SDI) and Universal Health Coverage (UHC) effective coverage index using Spearman correlation and linear regression analyses. Percentages are reported to 1 decimal place and rates are reported to 2 decimal places.

FINDINGS

In 2019, there were 559·2 million young people aged 10-24 years in the South-East Asia region and 335·0 million in the Western Pacific region; India and China remained the countries with greatest number of this age group. In 1990-2019, India had an absolute increase of 139·4 million adolescents, while China had a decrease of 134·3 million. In 2019, NCDs accounted for 27·3% (95% uncertainty interval 25·1 to 29·2) and 34·6% (33·5 to 36·1) of total deaths, and 49·8% (45·3 to 54·4) and 65·1% (60·6 to 69·3) of total DALYs in the South-East Asia and the Western Pacific regions, respectively. Neoplasms, cardiovascular diseases, and mental disorders were the leading causes of NCD burden in 42 countries. Kiribati had the highest rates of deaths (62·82 [50·77 to 76·11] per 100 000 population), YLLs (4364·73 [3545·04 to 5275·63] per 100 000 population), and DALYs (9368·73 [7713·65 to 11340·99] per 100 000 population) for NCDs, whereas Australia (6976·51 [5044·46 to 9190·01] per 100 000 population) and New Zealand (6716·81 [4827·25 to 8827·69] per 100 000 population) had the largest rates of YLDs due to NCDs. From 1990 to 2019 across both regions, the rate of death due to NCDs declined by over a third (-32·8% [-41·1 to -22·9] in the South-East Asia region and -40·0% [-48·6 to -30·4] in the Western Pacific region), and DALYs decreased by about 12% (-12·0% [-16·8 to -7·7] in the South-East Asia region and -12·8% [-17·7 to -8·7] in the Western Pacific region), whereas the proportion of NCD burden relative to all-cause burden increased (45·7% [32·9 to 61·7] for deaths and 41·2% [35·2 to 48·8] for DALYs in the South-East Asia region; 11·8% [7·1 to 21·5] for deaths and 18·2% [14·6 to 22·0] for DALYs in the Western Pacific region). The rate of deaths and DALYs due to NCDs decreased monotonically alongside increases in SDI (rs=-0·57 [95% CI -0·81 to -0·32] for deaths and rs=-0·30 [-0·61 to 0·03] for DALYs). The rate of deaths (rs=-0·89 [95% CI -0·97 to -0·80]) and DALYs (rs=-0·67 [-0·93 to -0·41]) due to NCDs also decreased alongside increases in the UHC effective coverage index.

INTERPRETATION

Specific preventive and health service measures are needed for adolescents and young adults in countries with different levels of socioeconomic development to reduce the burden from NCDs.

Exploration of Gut Microbiome Research in Africa: A Scoping Review

The crucial role of the gut microbiome in various diseases has led to increased interest in interventions and therapeutics targeting the human microbiome. Accordingly, the current scoping review analyzed the diseases and interventions involved in gut microbiome research in Africa. The electronic databases of PubMed, Google Scholar, and Scopus were searched from inception to October 2021. This study identified 48 studies involving 7073 study participants. Of the 48 studies, 20 (42%) used interventions to modulate gut microbiota, whereas the remaining 28 (58%) did not. Out of the total African countries, only 13% were involved in intervention-based gut microbiome research, whereas a larger proportion of 67% were not involved in any gut microbiome research. The interventions used in gut microbiome research in Africa include supplements, natural products, educational approaches, associated pathogens, albendazole, fresh daily yogurt, iron-containing lipid-based nutrient supplements, fecal microbiota transplant, and prophylactic cotrimoxazole. This scoping review highlights the current state of gut microbiome research in Africa. The findings of this review can inform the design of future studies and interventions aimed at improving gut health in African populations.

Unlock digital health promotion in LMICs to benefit the youth

As digital technologies such as smartphones and fitness bands become more ubiquitous, individuals can engage in self-monitoring and self-care, gaining greater control over their health trajectories along the life-course. These technologies appeal particularly to young people, who are more familiar with digital devices. How this digital transformation facilitates health promotion is therefore a topic of animated debate. However, most research to date focuses on the promise and peril of digital health promotion (DHP) in high-income settings, while DHP in low- and middle-income countries (LMICs) remain largely unexplored. This narrative review aims to fill this gap by critically examining key ethical challenges of implementing DHP in LMICs, with a focus on young people. In the existing literature, we identified potential impediments as well as enabling conditions. Aspects to consider in unlocking the potential of DHP include (1) addressing the digital divide and structural injustice in data-related practices; (2) engaging the target population and responding to their specific needs given their economic, cultural, and social contexts; (3) monitoring the quality and impact of DHP over time; and (4) improving responsible technology governance and its implementation. Addressing these concerns could result in meaningful health benefits for populations lacking access to more conventional healthcare resources.

Outcomes of Emergency Trauma Patients After the Implementation of Web Application Operating Systems

PURPOSE

Trauma has significant impacts on the livelihoods and well-being of patients. Prompt emergency, medical, and nursing care is the key to reducing mortality rates. Digital platforms have become important for patient care. This research aimed to evaluate patient outcomes after implementing a novel web application operating system in trauma care.

METHODS

A descriptive comparative study was conducted on trauma patients. The patients were divided into two groups: those who used the developed application (n = 70) and those who did not (n = 70). The patients' characteristics, the time of the trauma team's arrival at the emergency department (ED) and the length of stay in the ED, and patients' outcomes were collected from electronic medical records and the application database. A statistical analysis was performed to evaluate this data. Sixty registered nurses who used the application completed the survey on the feasibility of the application.

RESULTS

The activated trauma intervals for the non-application-used group and the application-used group were 5.0 ± 1.1 and 3.1 ± 0.4 minutes, respectively (p = .010). The length of stay in the ED for the non-application-used group and the application-used group were 30.1 ± 5.1 and 18.3 ± 6.2 minutes, respectively. A high level of agreement confirms the feasibility of the application.

CONCLUSIONS

This application improves patient outcomes in terms of length of stay. This mobile application can improve the cooperation and communication and efficacy of the trauma care team.

Effect and mechanism of total ginsenosides repairing SDS‑induced Drosophila enteritis model based on MAPK pathway

Inflammatory bowel disease (IBD) is a chronic recurrent gastrointestinal disease that seriously endangers human and animal health. Although the etiology of IBD is complex and the pathogenesis is not well understood, studies have found that genetic predisposition, diet and intestinal flora disorders are the main risk factors for IBD. The potential biological mechanism of total ginsenosides (TGGR) in the treatment of IBD remains to be elucidated. Surgery is still the main strategy for the treatment of IBD, due to the relatively high side effects of related drugs and the easy development of drug resistance. The purpose of the present study was to evaluate the efficacy of TGGR and explore the effect of TGGR on the intestinal inflammation induced by sodium dodecyl sulfate (SDS) in Drosophila and to initially explain the improvement effect and mechanism of TGGR on Drosophila enteritis by analyzing the levels of Drosophila-related proteins. During the experiment, the survival rate, climb index and abdominal characteristics of the Drosophila was recorded. Intestinal samples of Drosophila were collected for analysis of intestinal melanoma. The oxidative stress related indexes of catalase, superoxide dismutase and malondialdehyde were determined by spectrophotometry. Western blotting detected the expression of signal pathway-related factors. The effects of TGGR on growth indices, tissue indices, biochemical indices, signal pathway transduction and related mechanisms of SDS-induced Drosophila enteritis model were studied. The results showed that TGGR could repair SDS-induced enteritis of Drosophila through MAPK signaling pathway, improve survival rate and climbing ability and repair intestinal damage and oxidative stress damage. The results suggested that TGGR has potential application value in the treatment of IBD and its mechanism is related to the downregulation of phosphorylated (p)-JNK/p-ERK levels, which provides a basis for drug research in the treatment of IBD.

Non-communicable disease mortality in young people with a history of contact with the youth justice system in Queensland, Australia: a retrospective, population-based cohort study

BACKGROUND

Young people who have had contact with the criminal justice system are at increased risk of early death, especially from injuries. However, deaths due to non-communicable diseases (NCDs) in this population remain poorly described. We aimed to estimate mortality due to NCDs in people with a history of involvement with the youth justice system, compare NCD mortality rates in this population with those in the general population, and characterise demographic and justice-related factors associated with deaths caused by NCDs in people with a history of contact with the youth justice system.

METHODS

In this retrospective, population-based cohort study (the Youth Justice Mortality [YJ-Mort] study), we included all people aged 10-18 years (at baseline) charged with a criminal offence in Queensland, Australia, between June 30, 1993, and July 1, 2014. We probabilistically linked youth justice records with adult correctional records and national death records up to Jan 31, 2017. Indigenous status was ascertained from youth justice and adult correctional records, with individuals identified as Indigenous in either source classified as Indigenous in the final dataset. We estimated crude mortality rates and standardised mortality ratios (SMRs) for comparisons with data from the Australian general population. We identified risk factors for NCD deaths using competing-risks regression.

FINDINGS

Of 48 670 individuals aged 10-18 years (at baseline) charged with a criminal offence in Queensland, Australia, between June 30, 1993, and July 1, 2014, 11 897 (24·4%) individuals were female, 36 773 (75·6%) were male, and 13 250 (27·2%) were identified as identified as Indigenous. The median age at first contact with the youth justice system was 15 years (IQR 14-16), the median follow-up time was 13·4 years (8·4-18·4), and the median age at the end of the study was 28·6 years (23·6-33·6). Of 1431 deaths, 932 (65·1%) had a known and attributed cause, and 121 (13·0%) of these were caused by an NCD. The crude mortality rate from NCDs was 18·5 (95% CI 15·5-22·1) per 100 000 person-years among individuals with a history of involvement with the youth justice system, which was higher than among the age-matched and sex-matched Australian general population (SMR 1·67 [1·39-1·99]). Two or more admissions to adult custody (compared with none; adjusted sub-distribution hazard ratio 2·09 [1·36-3·22]), and up to 52 weeks in adult custody (compared with none; 1·98 [1·18-3·32]) was associated with NCD death.

INTERPRETATION

Young people with a history of contact with the justice system are at increased risk of death from NCDs compared with age-matched and sex-matched peers in the general Australian population. Reducing youth incarceration and providing young people's rights to access clinical, preventive, and restorative services should be a priority.

The unfinished agenda of communicable diseases among children and adolescents before the COVID-19 pandemic, 1990-2019: a systematic analysis of the Global Burden of Disease Study 2019

BACKGROUND

Communicable disease control has long been a focus of global health policy. There have been substantial reductions in the burden and mortality of communicable diseases among children younger than 5 years, but we know less about this burden in older children and adolescents, and it is unclear whether current programmes and policies remain aligned with targets for intervention. This knowledge is especially important for policy and programmes in the context of the COVID-19 pandemic. We aimed to use the Global Burden of Disease (GBD) Study 2019 to systematically characterise the burden of communicable diseases across childhood and adolescence.

METHODS

In this systematic analysis of the GBD study from 1990 to 2019, all communicable diseases and their manifestations as modelled within GBD 2019 were included, categorised as 16 subgroups of common diseases or presentations. Data were reported for absolute count, prevalence, and incidence across measures of cause-specific mortality (deaths and years of life lost), disability (years lived with disability [YLDs]), and disease burden (disability-adjusted life-years [DALYs]) for children and adolescents aged 0-24 years. Data were reported across the Socio-demographic Index (SDI) and across time (1990-2019), and for 204 countries and territories. For HIV, we reported the mortality-to-incidence ratio (MIR) as a measure of health system performance.

FINDINGS

In 2019, there were 3·0 million deaths and 30·0 million years of healthy life lost to disability (as measured by YLDs), corresponding to 288·4 million DALYs from communicable diseases among children and adolescents globally (57·3% of total communicable disease burden across all ages). Over time, there has been a shift in communicable disease burden from young children to older children and adolescents (largely driven by the considerable reductions in children younger than 5 years and slower progress elsewhere), although children younger than 5 years still accounted for most of the communicable disease burden in 2019. Disease burden and mortality were predominantly in low-SDI settings, with high and high-middle SDI settings also having an appreciable burden of communicable disease morbidity (4·0 million YLDs in 2019 alone). Three cause groups (enteric infections, lower-respiratory-tract infections, and malaria) accounted for 59·8% of the global communicable disease burden in children and adolescents, with tuberculosis and HIV both emerging as important causes during adolescence. HIV was the only cause for which disease burden increased over time, particularly in children and adolescents older than 5 years, and especially in females. Excess MIRs for HIV were observed for males aged 15-19 years in low-SDI settings.

INTERPRETATION

Our analysis supports continued policy focus on enteric infections and lower-respiratory-tract infections, with orientation to children younger than 5 years in settings of low socioeconomic development. However, efforts should also be targeted to other conditions, particularly HIV, given its increased burden in older children and adolescents. Older children and adolescents also experience a large burden of communicable disease, further highlighting the need for efforts to extend beyond the first 5 years of life. Our analysis also identified substantial morbidity caused by communicable diseases affecting child and adolescent health across the world.
