Sleep disturbance increases the risk of severity and acquisition of COVID-19: a systematic review and meta-analysis

BACKGROUND

Understanding the association between sleep quality and COVID-19 outcomes is crucial for effective preventive strategies and patient management. This systematic review aims to evaluate the impact of sleep quality as a risk factor for acquiring COVID-19 infection and the severity of the disease.

METHODS

A comprehensive search of electronic databases was conducted to identify relevant studies published from the inception of the COVID-19 pandemic which was 31st of December 2019 until 30 April 2023. Studies investigating the relationship between sleep quality and COVID-19 infection, or disease severity were included. Random effect meta-analysis was performed with odds ratios (OR) and their 95% confidence intervals (95% CI) as effect measures.

RESULTS

Out of the initial 1,132 articles identified, 12 studies met the inclusion criteria. All studies were observational studies (cohort, case-control, and cross-sectional). The association between sleep quality and COVID-19 infection risk was examined in 6 studies, The results of our meta-analysis showed that participants with poor sleep quality showed a 16% increase regarding the risk of COVID-19 acquisition (OR 1.16; 95% CI 1.03, 1.32; I2 = 65.2%, p = 0.02). Our results showed that participants with poor sleep quality showed a 51% increase in the incidence of primary composite outcome (OR 1.51; 95% CI 1.25, 1.81; I2 = 57.85%, p < 0.001). The result of our subgroup analysis also showed significantly increased risk of mortality (RR 0.67; 95% CI 0.50, 0.90; I2 = 31%, p = 0.008), and disease severity (OR 1.47; 95% CI 1.19, 1.80; I2 = 3.21%, p < 0.001) when comparing poor sleep group to those with good sleep quality.

CONCLUSION

This study highlights a significant association between poor sleep quality and an increased risk of COVID-19 infection as well as worse disease clinical outcomes.

Effect of alcohol on Brain-Derived Neurotrophic Factor (BDNF) blood levels: a systematic review and meta-analysis

Brain-Derived Neurotrophic Factor (BDNF) is a vital protein involved in neuronal development, survival, and plasticity. Alcohol consumption has been implicated in various neurocognitive deficits and neurodegenerative disorders. However, the impact of alcohol on BDNF blood levels remains unclear. This systematic review and meta-analysis aimed to investigate the effect of alcohol consumption on BDNF blood levels. A comprehensive search of electronic databases was conducted to identify relevant studies. Eligible studies were selected based on predefined inclusion criteria. Data extraction was performed, and methodological quality was assessed using appropriate tools. A meta-analysis was conducted to estimate the overall effect size of alcohol consumption on BDNF levels. A total of 25 studies met the inclusion criteria and were included in the final analysis. Alcohol use and BDNF blood levels were significantly correlated, according to the meta-analysis (p = 0.008). Overall, it was discovered that drinking alcohol significantly decreased BDNF levels (SMD: - 0.39; 95% CI: - 0.68 to - 0.10; I2: 93%). There was a non-significant trend suggesting that alcohol withdrawal might increase BDNF levels, with an SMD of 0.26 (95% CI: - 0.09 to 0.62; I2: 86%; p = 0.14). Subgroup analysis based on the source of BDNF demonstrated significant differences between the subgroups (p = 0.0008). No significant publication bias was observed. This study showed that alcohol consumption is associated with a significant decrease in BDNF blood levels. The findings suggest a negative impact of alcohol on BDNF levels regardless of alcohol dosage. Further studies are needed to strengthen the evidence and elucidate the underlying mechanisms.

Prevalence of asymptomatic malaria and associated factors among pregnant women in Ethiopia: systematic review and meta-analysis

The proactive identification of asymptomatic patients and the mitigation of associated problems are essential to the elimination of malaria. For asymptomatic malaria and related variables among pregnant women in Ethiopia, there are no national pooled estimates. As a result, the goal of this study is to compile thorough and compelling data from several Ethiopian investigations. Google Scholar, PubMed, Scopes, the Web of Science, the Cochrane Library, and African Journals Online were a few of the electronic resources that were accessed. The investigation included all observational studies. STATA version 15 was used to extract the data from the Microsoft Excel file and conduct the analysis. The estimated pooled prevalence of asymptomatic malaria among pregnant women was calculated using a random-effects model. An inverse variance index (I2) analysis was utilized to find heterogeneity. To assess the publication bias, funnel plots, and Egger's statistical tests were used. The study determined that the combined prevalence of asymptomatic malaria among pregnant women was 7.20 (95% confidence interval = 4.22, 10.18) and 4.69 (95% confidence interval = 2.77, 6.62) by microscopy and rapid diagnostic test, respectively. The presence of stagnant water near their home (odds ratio = 4.31; 95% confidence interval = 1.66, 11.20); not using insecticide-treated nets (odds ratio = 6.93; 95% confidence interval = 3.27, 14.71); the lack of indoor residual spray service (odds ratio = 2.68; 95% confidence interval = 1.63, 4.40); and the presence of pregnant women in their neighborhood (odds ratio = 3.14; 95% confidence interval = 1.4). This study showed that pregnant women have a high pooled prevalence of asymptomatic malaria. Women living in rural areas near stagnant water and those who never used insecticide-treated nets had a two-, four-, or six-fold higher prevalence of asymptomatic malaria, respectively. The use of advanced diagnostic techniques could produce a higher magnitude of the disease. For effective intervention toward elimination, active case detection at the community level is also advised.

New insights into the pathogenesis of primary biliary cholangitis asymptomatic stage

Primary biliary cholangitis (PBC) is a chronic cholestatic progressive liver disease and one of the most important progressive cholangiopathies in adults. Damage to cholangiocytes triggers the development of intrahepatic cholestasis, which progresses to cirrhosis in the terminal stage of the disease. Accumulating data indicate that damage to biliary epithelial cells [(BECs), cholangiocytes] is most likely associated with the intracellular accumulation of bile acids, which have potent detergent properties and damaging effects on cell membranes. The mechanisms underlying uncontrolled bile acid intake into BECs in PBC are associated with pH change in the bile duct lumen, which is controlled by the bicarbonate (HCO3-) buffer system "biliary HCO3- umbrella". The impaired production and entry of HCO3- from BECs into the bile duct lumen is due to epigenetic changes in expression of the X-linked microRNA 506. Based on the growing body of knowledge on the molecular mechanisms of cholangiocyte damage in patients with PBC, we propose a hypothesis explaining the pathogenesis of the first morphologic (ductulopenia), immunologic (antimitochondrial autoantibodies) and clinical (weakness, malaise, rapid fatigue) signs of the disease in the asymptomatic stage. This review focuses on the consideration of these mechanisms.

Three Distraction Methods for Pain Reduction During Colonoscopy: A Randomized Controlled Trial Evaluating the Effects on Pain and Anxiety

PURPOSE

The aim of this study was to compare the effects of distraction methods on pain, anxiety, and satisfaction during a colonoscopy.

DESIGN

This experimental research was conducted as a single-center, randomized, parallel-group trial.

METHODS

A total of 120 patients were recruited and randomized into 4 groups (music, stress ball, audiovisual distraction, and control). The data were collected using individual an identification form, observation form, the Visual Analog Scale, and the State-Trait Anxiety Inventory.

FINDINGS

Pain severity during colonoscopy was found to be lower in the intervention (music and audiovisual distraction) groups compared to the stress ball and control groups (P < .001).There was no statistically significant difference between the pre- and postanxiety levels in the intervention groups compared to the control group. After the colonoscopy, satisfaction levels were significantly higher in the music group compared to the audiovisual, control, and stress ball groups (P < .001).

CONCLUSIONS

Distraction methods used during colonoscopy were found to reduce pain. Although sedation is widely used during a colonoscopy procedure and is accepted as a general standard, music and VR can be used as effective alternative strategies in reducing pain for colonoscopy patients.

Relationship between severe mental illness and physical multimorbidity: a meta-analysis and call for action

BACKGROUND

People with severe mental illness (SMI) have a higher prevalence of several chronic physical health conditions, and the prevalence of physical multimorbidity is expected to rise. The aim of this study was to assess the strength of the association between SMI and physical multimorbidity.

STUDY SELECTION AND ANALYSIS

We systematically searched PubMed/Medline, Scopus, Embase, Web of Science, PsycINFO and the behavioural sciences collection databases, from inception to 31 January 2023, for studies that investigated the association between SMI and physical multimorbidity. Humans of any age either clinically diagnosed and/or currently receiving treatment for SMI, specified as schizophrenia (and related psychotic disorders), bipolar disorder and psychotic depression, were eligible. Data from studies selected for inclusion were converted into ORs, with a subsequent meta-analysis conducted.

FINDINGS

We included 19 studies with a total of 194 123 patients with SMI with different diagnoses and drawn from the general population. The pooled OR for physical multimorbidity in people with versus without SMI was 1.84 (95% CI 1.33 to 2.54), with the analysis indicating a high level of heterogeneity (98.38%). The other 15 studies included in the systematic review for which it was not possible to conduct a meta-analysis showed strong associations between SMI and physical multimorbidity.

CONCLUSIONS

The current evidence highlights the link between SMI and physical multimorbidity. A multidisciplinary approach is now urgent to develop the best models of services tailored to patients with SMI with physical multimorbidities to improve physical, mental and social outcomes.

Association between periodontitis and postoperative complications in hospital medical surgical procedures: a systematic review

Background

Periodontitis is potentially harmful in the perioperative period due to biofilm generating a environment for bacteria to spread and colonize other anatomical areas, which can generate a potential risk of infection, delayed healing, increased morbidity, and even induce avulsion in intubated patients, and subsequent aspiration or ingestion of teeth with increased mobility.

Objective

Associate the presence of periodontitis and postoperative complications in patients who underwent an in-hospital medical surgical procedure.

Methods

A systematic review based on studies extracted from PubMed and Scopus was carried out on June 10, 2020, based on the Population, Intervention, Comparison and Result search strategy. As inclusion criteria, the studies had to include all the disaggregated terms of the research question, have a publication date of less than 15 years, and the target population had to have undergone elective hospital medical-surgical interventions. The exclusion criteria corresponded to not presenting an analytical or experimental observational study design, not having made a periodontal clinical diagnosis of the study subjects, and not expressing in the results the presence of postoperative medical-hospital complications. Articles were assessed for quality by supplementing the STROBE guideline and Newcastle Ottawa, for risk of bias by supplementing the STROBE guideline and the Cochrane Collaboration handbook tool.

Results

A total of 131 articles were obtained, which were subjected to a selection process, resulting in 5 final analytical observational studies. A meta-analysis was performed and determined that periodontitis was a risk factor to postoperative complications after surgical procedures with an OR = 4,76; 95%CI [1,11-20,41].

Conclusions

Optimize the guidelines for assessing quality and risk of bias can make their comparison with other studies complex, however it was determined in a statistically significant way that patients with periodontitis have a higher risk of generating postoperative complications after a medical hospital surgery.

Pregnancy rate, maternal and neonatal outcomes among breast cancer survivors: A systematic review

AIM

This study investigated the pregnancy rate, maternal and neonatal outcomes, and breast cancer (BC) recurrence status after pregnancy among BC survivors.

DESIGN

A systematic review.

METHODS

Electronic databases such as PubMed, Web of Science [WOS], Scopus, ScienceDirect, Google Scholar, and Scientific Information Database were systematically searched. The quality of included studies was evaluated using the Newcastle-Ottawa Scale (NOS). Observational studies reported the pregnancy rate, maternal and neonatal outcomes among reproductive-aged BC survivors, and the recurrence status of BC after pregnancy were eligible to include in this study.

RESULTS

Of the 29 included studies, 13 studies were prospective cohorts or prospective multicenter or population-based cohorts, 14 studies were retrospective cohort or retrospective population-based cohort studies, and two studies were cross-sectional retrospective surveys or population-based descriptive studies. This systematic review showed that the pregnancy rate was estimated at 3.1%-48.5% among BC survivors who attempted to conceive. The most prevalent maternal outcomes of pregnancy were miscarriage (1.8%-33.3%) and induced abortion (5.0%-44%) as well as preterm birth (PTB) or very PTB (1.2%-21.1%), and twin birth (1.1%-38.8%) were the most prevalent neonatal outcomes occurring among BC survivors, respectively. In addition, most of the included studies indicated that pregnancy had no adverse effect on the status of BC recurrence among survivors. Surviving women can be encouraged and receive a carefully multidisciplinary approach regarding healthy pregnancy. No Patient or Public Contribution.

Molecular biomarkers for objective assessment of symptomatic pulpitis: A systematic review and meta-analysis

BACKGROUND

Inflammatory biomarkers are potentially useful targets for pulpal diagnostic tests that can identify pulp status and predict vital pulp treatment (VPT) outcome, however, their accuracy is unknown.

OBJECTIVES

(1) Calculate sensitivity, specificity and diagnostic odds ratio (DOR) of previously investigated pulpitic biomarkers; (2) Determine if biomarker levels discriminate between clinical diagnoses of pulpitis based on the presence or absence of spontaneous pain (3) Evaluate if biomarker level can predict VPT outcome.

METHODS

Searches: PubMed/MEDLINE, Ovid SP, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, Embase, Web of Science and Scopus in May 2023.

INCLUSION

prospective and retrospective observational studies and randomized trials. Participants were humans with vital permanent teeth and a well-defined pulpal diagnosis.

EXCLUSION

deciduous teeth, in vitro and animal studies. Risk of bias was assessed with modified-Downs and Black quality assessment checklist. Meta-analysis was performed using bivariate random effect model in Meta-DiSc 2.0 and RevMan and the quality of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation.

RESULTS

Fifty-six studies were selected, reporting >70 individual biomolecules investigating pulpal health and disease at the gene and protein level. Most studies were of low and fair quality. Among the biomolecules investigated, IL-8 and IL-6 demonstrated a level of diagnostic accuracy with high sensitivity, specificity and DOR to discriminate between healthy pulps and those exhibiting spontaneous pain suggestive of IRP (low-certainty evidence). However, none was shown to have high DOR and the ability to discriminate between pulpitic states (very low certainty evidence). Limited data suggests high levels of matrix metalloproteinase 9 correlate with poorer outcomes of full pulpotomy.

DISCUSSION

The inability of identified molecular inflammatory markers to discriminate between dental pulps with spontaneous and non-spontaneous pain should shift the focus to improved study quality or the pursuit of other molecules potentially associated with healing and repair.

CONCLUSIONS

Low-quality evidence suggests IL-8 and IL-6 demonstrated level of diagnostic accuracy to discriminate between healthy pulps and those exhibiting spontaneous pain. There is a need for standardized biomarker diagnostic and prognostic studies focusing on solutions that can accurately determine the degree of pulp inflammation.

Unique Properties of Yeast Probiotic Saccharomyces boulardii CNCM I-745: A Narrative Review

Probiotics, both bacterial and yeast, have long been associated with a beneficial health history and human well-being. Among yeasts, Saccharomyces is a genus that is efficacious in rendering better human health, with Saccharomyces boulardii (S. boulardii) CNCM I-745 being classified as a probiotic agent. The present review highlights the unique properties of S. boulardii and its rolein the prevention of antibiotic-associated diarrhea (AAD) and pediatric acute gastroenteritis (PAGE) in comparison to bacterial probiotics. Its unique properties,such as viability over a wide pH range, inability to acquire antibiotic resistance genes, and property to achieve a steady state rapidly, have given S. boulardii an edge over bacterial probiotics. In AAD patients, prophylactic use of S. boulardii has shown a significantly lower risk of AAD (in comparison to controls) and restored the diversity of gut microbiota. Among Indian children with PAGE, S. boulardii CNCM I-745 was found superior to Lactobacillus rhamnosus GG and four strains of Bacillus clausii in shortening the duration of diarrhea and reducing the length of hospital stay. S. boulardii CNCM I-745 being considered a safe probiotic for use in children and adults also finds recommendations in several international guidelines for the management of acute diarrhea. The current review discusses evidence for the proven efficacy and safety of S. boulardii CNCM I-745 as a probiotic for preventing gastrointestinal disorders.

Comparative evaluation of clinical outcomes of dapagliflozin and empagliflozin in type-2 diabetes mellitus

BACKGROUND

Sodium-glucose transporter 2 (SGLT-2) inhibitors provide additional benefits besides glycemic control.

AIM

This study aims to compare the clinical outcomes of dapagliflozin and empagliflozin.

METHODS

This retrospective study evaluated data retrieved from medical records of patients who were under follow-up with the diagnosis of type 2 diabetes mellitus (T2DM) and were started on dapagliflozin or empagliflozin treatment between January 1, 2017, and June 1, 2020. Demographic features, comorbidities, clinical features, duration of diabetes, baseline, and follow-up laboratory test results were recorded. The significance level was set at p < 0.05.

RESULTS

This study comprised 342 patients who are on the treatment with dapagliflozin (n = 228) or empagliflozin (n = 114). The glycosylated hemoglobin a1c (HBA1C) level was significantly decreased in both the dapagliflozin (8.18-7.59, p < 0.001) and empagliflozin (8.35-7.58, p < 0.001) groups. The urine albumin-to-creatinine ratio (ACR) was also decreased in both groups. A decrease in urine ACR was observed independent of using a renin-angiotensin-aldosterone system (RAAS) blocker both in the whole group and in patients with diabetic nephropathy. The time to addition of a new anti-diabetic agent to the treatment was shorter in the dapagliflozin group (14.4 months vs 17.7 months, p = 0.041, respectively).

CONCLUSION

Dapagliflozin and empagliflozin are the drugs to choose for renoprotection in diabetics independent of the use of a RAAS blocker. Even the time to addition of a new anti-diabetic agent is longer in the empagliflozin group, head-to-head comparative trials are needed to asess the potential differences in this regard.

What outcomes do studies use to measure the impact of prognostication on people with advanced cancer? Findings from a systematic review of quantitative and qualitative studies

BACKGROUND

Studies evaluating the impact of prognostication in advanced cancer patients vary in the outcomes they measure, and there is a lack of consensus about which outcomes are most important.

AIM

To identify outcomes previously reported in prognostic research with people with advanced cancer, as a first step towards constructing a core outcome set for prognostic impact studies.

DESIGN

A systematic review was conducted and analysed in two subsets: one qualitative and one quantitative. (PROSPERO ID: CRD42022320117; 29/03/2022).

DATA SOURCES

Six databases were searched from inception to September 2022. We extracted data describing (1) outcomes used to measure the impact of prognostication and (2) patients' and informal caregivers' experiences and perceptions of prognostication in advanced cancer. We classified findings using the Core Outcome Measures in Effectiveness Trials (COMET) initiative taxonomy, along with a narrative description. We appraised retrieved studies for quality, but quality was not a basis for exclusion.

RESULTS

We identified 42 eligible studies: 32 quantitative, 6 qualitative, 4 mixed methods. We extracted 70 outcomes of prognostication in advanced cancer and organised them into 12 domains: (1) survival; (2) psychiatric outcomes; (3) general outcomes; (4) spiritual/religious/existential functioning/wellbeing, (5) emotional functioning/wellbeing; (6) cognitive functioning; (7) social functioning; (8) global quality of life; (9) delivery of care; (10) perceived health status; (11) personal circumstances; and (12) hospital/hospice use.

CONCLUSION

Outcome reporting and measurement varied markedly across the studies. A standardised approach to outcome reporting in studies of prognosis is necessary to enhance data synthesis, improve clinical practice and better align with stakeholders' priorities.

Conservative Management of Acute Lateral Ligaments of the Ankle Injuries: An Analytical Literature Review

Injuries to the lateral ligaments of the ankle are among the most frequent sporting injuries. These injuries constitute a significant portion of all sports-related injuries. Nearly all cases involve damage to either the anterior talofibular ligament (ATFL) or the calcaneofibular ligament (CFL). While they are generally considered to be mild injuries, without adequate rehabilitation and treatment, these injuries often result in lingering symptoms for many patients for a period ranging from 6 weeks to 18 months. Subsequently, this analysis seeks to assess the non-surgical, conservative approaches currently employed in managing lateral ligament injuries of the ankle. Therefore, this assessment explores the variations and effectiveness of conservative treatment approaches based on the injury's severity and the mechanisms of trauma. The study conducted an analytical literature review that relied on diverse sources, including orthopedic books, e-books, articles, journals, and internet databases, to accomplish this. The main sources were obtained from reputable databases such as UpToDate, NCBI, and PubMed. Collectively, these sources provide definitions, outlines, evaluations, and discussions related to the topic. As such, they facilitated the formulation of an informed conclusion on the approach to treating lateral ligament injuries of the ankle complex. The reviewed literature shows that early and effective initial treatment involving pain management, prompt resumption of weight-bearing activities, limited immobilisation, and targeted physical therapy yields favorable outcomes for minor-grade sprains and is an effective preventive measure against recurrent injuries. Accordingly, athletes who experience regular ankle sprains should consider prophylactic bracing or taping to lower the risk of re-injury while enhancing their functionality. Notably, the existing functional and conservative management methods demonstrate and yield positive post-treatment outcomes. Nonetheless, the efficiency and effectiveness of these treatments depend on the specific nature of the injury and the unique traits of the individuals who sustain it. Consequently, these factors must be considered for when determining the appropriate treatment approach.

Current Surgical Outcomes of Nasal Tip Grafts in Rhinoplasty: A Systematic Review

BACKGROUND

Refinement of the nasal tip plays an important role in rhinoplasty surgery outcomes and may be considered the most technically challenging aspect of the procedure. Numerous techniques have been described for nasal tip augmentation utilizing grafts. The aim of this study was to systematically review the existing literature on nasal tip grafts and appraise it critically.

METHODS

A PubMed search was performed to identify journal articles related to nasal tip grafts from the past decade. A total of 44 studies met inclusion criteria. The Newcastle-Ottawa Quality Assessment Scale and Jadad scale were used to appraise 38 observational studies and six randomized trials, respectively, to determine the quality of the studies.

RESULTS

Critical assessment revealed that the studies were highly variable in focus and encompassed autologous, homologous, and alloplastic grafts. The quality of the data included an average Newcastle-Ottawa Quality Assessment Scale score of 6.5 (out of 9) and Jadad score of 2.5 (out of 5). A majority of studies (86.4%) included objective outcomes using anthropometric measurements and a portion of studies (27.3%) also included patient-reported outcomes.

CONCLUSIONS

The results of this systematic review suggest that more than one type of nasal tip graft may result in satisfactory outcomes. This review provides an expansive collection of studies on nasal tip grafts, which can serve as an invaluable tool for the plastic surgeon engaging in rhinoplasty.

Physical activity and exercise for the prevention and management of mild cognitive impairment and dementia: a collaborative international guideline

BACKGROUND

Physical activity and exercise have been suggested as effective interventions for the prevention and management of mild cognitive impairment (MCI) and dementia, but there are no international guidelines.

OBJECTIVES

To create a set of evidence- and expert consensus-based prevention and management recommendations regarding physical activity (any bodily movement produced by skeletal muscles that results in energy expenditure) and exercise (a subset of physical activity that is planned, structured, repetitive), applicable to a range of individuals from healthy older adults to those with MCI/dementia.

METHODS

Guideline content was developed with input from several scientific and lay representatives' societies. A systematic search across multidisciplinary databases was carried out until October 2021. Recommendations for prevention and management were developed according to the GRADE and complemented by consensus statements from the expert panels.

RECOMMENDATIONS

Physical activity may be considered for the primary prevention of dementia. In people with MCI there is continued uncertainty about the role of physical activity in slowing the conversion to dementia. Mind-body interventions have the greatest supporting evidence. In people with moderate dementia, exercise may be used for maintaining disability and cognition. All these recommendations were based on a very low/low certainty of evidence.

CONCLUSIONS

Although the scientific evidence on the beneficial role of physical activity and exercise in preserving cognitive functions in subjects with normal cognition, MCI or dementia is inconclusive, this panel, composed of scientific societies and other stakeholders, recommends their implementation based on their beneficial effects on almost all facets of health.

Disordered eating behaviours and body shape dissatisfaction among adolescents with type 1 diabetes: a cross sectional study

BACKGROUND

Disordered eating behaviours (DEBs) are variations in regular eating patterns and behaviours and might include symptoms and behaviours of eating disorder with lower level of severity. Such behaviours are common during adolescence at which time several physical and psychological changes occur favouring unhealthy dietary behaviours. Although the magnitude of DEBs is high among high-income countries, similar data are limited among adolescents with diabetes in low-income countries including Ethiopia. This study aimed to assess the magnitude of DEBs and its relationship with body shape dissatisfaction among adolescents with diabetes on follow-up at selected public hospitals in Addis Ababa, Ethiopia.

METHODS

Hospital based cross sectional study was conducted among randomly selected 395 adolescents with diabetes attending public hospitals in Addis Ababa from January to December, 2021. Data were collected using structured pretested standard diabetes eating problem survey revised (DEPS-R) questionnaire, body part satisfaction scale of 8 items, and anthropometric measurements. Descriptive statistics such as median alongside interquartile range was used to describe the continuous variables. Binary bivariable and multivariable logistic regression was used for data analysis. Mann-Whitney U-test and Kruskal-Wallis test were used to evaluate the difference between median scores of independent variables. Adjusted odds ratios (AOR) alongside 95% confidence intervals (CIs) were estimated to measure the strength of association between variables of interest.

RESULTS

The magnitude of disordered eating behaviours within the last 30 days was 43.3%, [95% CI: (38%, 48%)]. In multivariable analysis, body shape dissatisfaction [AOR = 2.21, 95% CI (1.28, 3.82, p = 0.0001)], family history of diabetes mellitus [AOR = 1.59, 95% CI (1.03, 2.47, p = 0.038)], late adolescence period [AOR = 2.10, 95% CI (1.33, 3.34, p = 0.002)], having diabetic complication[AOR = 2.32, 95% CI (1.43, 3.75, p = 0.001)],and being overweight [AOR = 2.25, 95% CI (1.32, 3.82, p = 0.003)] were significantly associated with DEBs.

CONCLUSIONS

The magnitude of DEBs was high among the study participants. Body shape dissatisfaction, family history of diabetes mellitus, being in late adolescence period, diabetic complication, and nutritional status of adolescents were significantly associated with DEBs. Therefore, preventive interventions need to be designed by all relevant actors working on health promotion of young population to address factors influencing DEBs among adolescent population with diabetes.

Evidence relating cigarettes, cigars and pipes to cardiovascular disease and stroke: Meta-analysis of recent data from three regions

BACKGROUND

More recent data are required relating to disease risk for use of various smoked products and of other products containing nicotine. Earlier we published meta-analyses of recent results for chronic obstructive pulmonary disease and lung cancer on the relative risk (RR) of current compared to never product use for cigarettes, cigars and pipes based on evidence from North America, Europe and Japan. We now report corresponding up-to-date evidence for acute myocardial infarction (AMI), ischaemic heart disease (IHD) and stroke.

AIM

To estimate, using recent data, AMI, IHD and stroke RRs by region for current smoking of cigarettes, cigars and pipes.

METHODS

Publications in English from 2015 to 2020 were considered that, based on epidemiological studies in the three regions, estimated the current smoking RR of AMI, IHD or stroke for one or more of the three products. The studies should involve at least 100 cases of stroke or cardiovascular disease (CVD), not be restricted to populations with specific medical conditions, and should be of cohort or nested case-control study design or randomized controlled trials. A literature search was conducted on MEDLINE, examining titles and abstracts initially, and then full texts. Additional papers were sought from reference lists of selected papers, reviews and meta-analyses. For each study identified, we entered the most recent available data on current smoking of each product, as well as the characteristics of the study and the RR estimates. Combined RR estimates were derived using random-effects meta-analysis for stroke and, in the case of CVD, separately for IHD and AMI. For cigarette smoking, where far more data were available, heterogeneity was studied by a wide range of factors. For cigar and pipe smoking, a more limited heterogeneity analysis was carried out. A more limited assessment of variation in risk by daily number of cigarettes smoked was also conducted. Results were compared with those from previous meta-analyses published since 2000.

RESULTS

Current cigarette smoking: Ten studies gave a random-effects RR for AMI of 2.72 [95% confidence interval (CI): 2.40-3.08], derived from 13 estimates between 1.47 and 4.72. Twenty-three studies gave an IHD RR of 2.01 (95%CI: 1.84-2.21), using 28 estimates between 0.81 and 4.30. Thirty-one studies gave a stroke RR of 1.62 (95%CI: 1.48-1.77), using 37 estimates from 0.66 to 2.91. Though heterogeneous, only two of the overall 78 RRs were below 1.0, 71 significantly (P < 0.05) exceeding 1.0. The heterogeneity was only partly explicable by the factors studied. Estimates were generally higher for females and for later-starting studies. They were significantly higher for North America than Europe for AMI, but not the other diseases. For stroke, the only endpoint with multiple Japanese studies, RRs were lower there than for Western studies. Adjustment for multiple factors tended to increase RRs. Our RR estimates and the variations by sex and region are consistent with earlier meta-analyses. RRs generally increased with amount smoked. Current cigar and pipe smoking: No AMI data were available. One North American study reported reduced IHD risk for non-exclusive cigar or pipe smoking, but considered few cases. Two North American studies found no increased stroke risk with exclusive cigar smoking, one reporting reduced risk for exclusive pipe smoking (RR 0.24, 95%CI: 0.06-0.91). The cigar results agree with an earlier review showing no clear risk increase for IHD or stroke.

CONCLUSION

Current cigarette smoking increases risk of AMI, IHD and stroke, RRs being 2.72, 2.01 and 1.62. The stroke risk is lower in Japan, no increase was seen for cigars/pipes.

Influence of care group participation on infant and young child feeding, dietary diversity, WASH behaviours and nutrition outcomes in rural Zimbabwe

Background

The care group approach (CGA) is a community-based nutrition behaviour change strategy centred on 'peer-to-peer learning' through women support groups.

Objective

To assess the impact of the CGA on the adoption of appropriate infant and young child feeding (IYCF), dietary diversity and water, sanitation and hygiene (WASH) practices, and associated nutrition-related outcomes.

Methods

A retrospective cohort study used a mixed-method approach in selected rural districts in Zimbabwe in June 2022. A structured questionnaire was used to collect data on IYCF, diet quality, WASH and child morbidity. Binary logistic regression was used to evaluate the association between exposure and outcome. Significance was at p<0.05.

Results

A total of 127 exposed and 234 controls were enrolled. There was no significant difference between exposed and controls on the prevalence of; diarrhoea (p=0.659), cough (p=0.191) and fever (p=0.916). No significant difference was observed in the proportion ever breastfed (p=0.609), Children with Adequate Dietary Diversity Score (p=0.606) across the two groups. However, the proportion of families with adequate Household Dietary Diversity Score (HDDS) (p=0.005) and Minimum Dietary Diversity for Women (MDD-W) (p=0.009) were significantly higher in exposed than controls. Knowledge on all promoted behaviours was significantly higher in the exposed than in controls with the exception of exclusive breast feeding. While the practices were significantly higher in exposed compared with controls for: 'Appropriate complementary feeding for children aged 6-24 months' (p=0.001), 'good nutrition for women of reproductive age' (p=0.001), 'production and consumption of diverse nutritious food' (p=0.001) and 'production and consumption of biofortified crops' (p=0.001).

Conclusions

The results showed that CGA potential to increase knowledge and achieve nutrition and health-related behaviour change in low-income settings if integrated into existing community programmes. Interestingly, HDDS and MDD-W were significantly higher in exposed than controls. However, more research is required to obtain conclusive results.

Cytomegalovirus Pneumonia in Inflammatory Bowel Disease: Literature Review and Clinical Recommendations

Aim

The objective was to elucidate the correlation between CMVP and immunosuppressive therapy in IBD patients, we hope this review could expand on the significance of CMV as an opportunistic pathogen and the potential impact on morbidity and mortality in IBD patients.

Methods

Records and clinical trajectories linked to CMVP in IBD patients were extracted from the PubMed database, irrespective of language barriers. The reference lists incorporated in these studies were manually inspected. Conclusions were generated using straightforward descriptive analysis.

Results

In total, 18 IBD patients, including Crohn's disease (CD, 67%) and Ulcerative Colitis (UC, 33%), affected by CMVP were identified from 17 published articles. A minority of these patients (17%) exhibited active disease, whereas the majority (83%) presented with quiescent disease. Fever (100%) and dyspnea (44%) emerged as the most prevalent clinical symptoms. All the patients had undergone immunosuppressive therapy. A significant proportion, up to 89%, had received thiopurine treatment prior to the CMVP diagnosis. Interestingly, none of the patients were subjected to biological therapy. Half of the patients manifested with Hemophagocytic Lymphohistiocytosis (HLH). Almost all patients (94%) were administered antiviral treatment and a substantial 83% experienced full recovery. Immunosuppressive agents were either tapered or discontinued altogether. A subset of patients, 17%, suffered fatal outcomes.

Conclusion

Our findings underscore the need for heightened suspicion of CMVP in IBD patients who exhibit symptoms such as fever and dyspnea. During the COVID-19 pandemic, CMVP should be considered a potential differential diagnosis. It was observed that CMVP primarily transpires during CD remission. Azathioprine emerged as the predominant immunosuppressant linked to CMV reactivation. The prompt application of effective antiviral therapy can substantially enhance patient outcomes. CMV vaccine might serve as a viable prevention strategy.

Lipid profile and risk of cardiovascular disease in adult transgender men receiving cross-sex hormone therapy: a systematic review

CONTEXT

A recent US national survey of the health status of the male transgender population has raised awareness about the little-studied relationship between testosterone hormone therapy in transgender men and cardiovascular outcomes.

OBJECTIVE

The aim of this systematic review was to assess the relationship between cross-sex hormone therapy in transgender men and lipid profiles and cardiovascular risk.

DATA SOURCES

The PubMed, SciELO, SpringerLink, and EBSCOhost databases were searched up to March 2021 for studies assessing the association between cross-sex hormone therapy and the incidence of outcomes related to cardiovascular disease in transgender men over 18 years of age .

DATA EXTRACTION

Data extracted were sorted into clinical data (systolic, diastolic, and mean blood pressure), anthropometric data (body mass index, weight, waist circumference, fat mass, and lean mass), and biochemical data (triglycerides, total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], very low-density lipoprotein cholesterol [VLDL-C], and the HDL-C to LDL-C ratio).

DATA ANALYSIS

Study quality was appraised independently by two reviewers using the Cochrane tools for assessment of methodological quality or risk of bias in nonrandomized studies, and the Newcastle-Ottawa Scale was applied. Of 735 studies identified, 11 were included in the review. Most studies reported no change in cholesterol or triglyceride levels after hormone treatment. A reduction in HDL-C levels was observed in 7 of 11 studies, although this alone cannot be considered a cardiovascular risk factor. Likewise, clinical and anthropometric findings showed no changes predictive of cardiovascular risk.

CONCLUSIONS

Although these findings suggest that hormone therapy may lead to a decrease in HDL-C levels and an increase in LDL-C levels, they are insufficient to establish a relationship with cardiovascular disease. Furthermore, no significant effects on metabolic and anthropometric values were found. Further studies with higher quality and longer follow-up periods are needed to establish cardiovascular risk.

The Automated Systematic Search Deduplicator (ASySD): a rapid, open-source, interoperable tool to remove duplicate citations in biomedical systematic reviews

BACKGROUND

Researchers performing high-quality systematic reviews search across multiple databases to identify relevant evidence. However, the same publication is often retrieved from several databases. Identifying and removing such duplicates ("deduplication") can be extremely time-consuming, but failure to remove these citations can lead to the wrongful inclusion of duplicate data. Many existing tools are not sensitive enough, lack interoperability with other tools, are not freely accessible, or are difficult to use without programming knowledge. Here, we report the performance of our Automated Systematic Search Deduplicator (ASySD), a novel tool to perform automated deduplication of systematic searches for biomedical reviews.

METHODS

We evaluated ASySD's performance on 5 unseen biomedical systematic search datasets of various sizes (1845-79,880 citations). We compared the performance of ASySD with EndNote's automated deduplication option and with the Systematic Review Assistant Deduplication Module (SRA-DM).

RESULTS

ASySD identified more duplicates than either SRA-DM or EndNote, with a sensitivity in different datasets of 0.95 to 0.99. The false-positive rate was comparable to human performance, with a specificity of > 0.99. The tool took less than 1 h to identify and remove duplicates within each dataset.

CONCLUSIONS

For duplicate removal in biomedical systematic reviews, ASySD is a highly sensitive, reliable, and time-saving tool. It is open source and freely available online as both an R package and a user-friendly web application.

Experiences of stigma, psychological distress, and facilitative coping among pregnant people with gestational diabetes mellitus

BACKGROUND

Gestational diabetes mellitus (GDM) has been rising in the United States, and it poses significant health risks to pregnant individuals and their infants. Prior research has shown that individuals with GDM also experience prevalent stress and mental health issues, which can further contribute to glucose regulation difficulties. Stigma associated with GDM may contribute to these mental health challenges, yet there is a lack of focused research on GDM-related stigma, its impact on psychological health, and effective coping mechanisms. Thus, this qualitative study aims to understand individuals' experiences related to GDM stigma, mental health, and facilitative coping.

METHODS

In-depth, semi-structured interviews were conducted with 14 individuals with a current or recent (within the last year) diagnosis of GDM. Thematic analysis was employed to guide data analysis.

RESULTS

Four themes emerged from data analysis: (1) experience of distal GDM stigma including stigmatizing provider interactions, stigma from non-medical spaces, and intersecting stigma with weight, (2) internalized GDM stigma, such as shame, guilt, and self-blame, (3) psychological distress, which included experiences of stress and overwhelm, excessive worry and fear, and loneliness and isolation, and (4) facilitative coping mechanisms, which included diagnosis acceptance, internet-based GDM community, active participation in GDM management, social and familial support, and time for oneself.

CONCLUSIONS

Findings demonstrate the relevance of GDM stigma in mental health among people with GDM and the need for addressing GDM stigma and psychological health in this population. Interventions that can reduce GDM stigma, improve psychological wellness, and enhance positive coping may facilitate successful GDM management and healthy birth outcomes. Future quantitative, theory-driven research is needed to understand the prevalence of GDM stigma experiences and mechanisms identified in the current study, as well as among marginalized populations (e.g., individuals of color, sexual and gender minorities).

Waste anesthetic gases have a significant association with deoxyribonucleic acid (DNA) damage: A systematic review and meta-analysis of 2,732 participants

Introduction

Operating room workers are at risk of experiencing adverse effects due to occupational exposure to waste anesthetic gases (WAGs). One of the consequences of long-term WAGs exposure is the probability of developing deoxyribonucleic acid (DNA) damage. This systematic review investigated the link between WAGs and DNA damage in operating room workers.

Methods

PubMed, Science Direct, ProQuest, Scopus, and EbscoHost, as well as hand-searching, were used to find literature on the relationship between WAGs and DNA damage. Three independent reviewers independently assessed the study's quality. Meta-analysis was conducted for several DNA damage indicators, such as comet assay (DNA damage score, tail's length, tail's DNA percentage), micronuclei formation, and total chromosomal aberration.

Results

This systematic review included 29 eligible studies (2732 participants). The majority of the studies used a cross-sectional design. From our meta-analysis, which compared the extent of DNA damage in operating room workers to the unexposed group, operating room workers exposed to WAGs had a significantly higher DNA damage indicator, including DNA damage score, comet tail's length, comet tail's DNA percentage, micronuclei formation, and total chromosomal aberration (p < 0.05) than non-exposed group.

Conclusion

Waste anesthetic gases have been found to significantly impact DNA damage indicators in operating room personnel, including comet assay, micronuclei development, and chromosomal aberration. To reduce the impact of exposure, hospital and operating room personnel should take preventive measures, such as by adapting scavenger method.

Association of chronic periodontitis with multiple sclerosis: A systematic review and meta-analysis

BACKGROUND

Chronic periodontitis (CP) is a multifactorial, chronic inflammatory disease of microbial etiology that manifests as a result of the dysfunction of the immune mechanism, culminating in the destruction of the alveolar bone of the jaws. Multiple sclerosis (MS) is an autoimmune disorder that affects the central nervous system (CNS), leads to demyelination and degeneration of nerve axons and often causes severe physical and/or cognitive impairment. As CP and MS involve inflammatory mechanisms and immune dysfunction, researchers have attempted to study the association between them.

AIM

To systematically review the literature on the epidemiological association between CP and MS in adults.

METHODS

PRISMA 2020 statement was used in the study protocol. The design was done according to the Cochrane methodology. A comprehensive literature search was performed in PubMed, Scopus and Cochrane databases; a manual search and evaluation of the gray literature was also performed. The meta-analysis was performed by Review Manager (RevMan) 5.4. Odds ratio (OR) with 95% confidence interval (CI) was defined as the effect size of the outcome. Heterogeneity was assessed by Chi-square and I2. The articles evaluated were written in English, without a time limit, concern observational studies (patient-controls) and report the diagnostic criteria of the diseases. Duplicate entries were excluded. To evaluate the reliability of the results of each study, Newcastle-Ottawa Scale (NOS) and GRADE tools were used. Two independent reviewers did all evaluations with a resolution of discrepancies by a third.

RESULTS

Meta-analysis included three observation studies examined 3376 people. MS patients are significantly more likely to be diagnosed with CP than healthy controls (OR 1.93, 95% CI 1.54-2.42, p<0.0001).

CONCLUSION

A high prevalence of CP was found among MS patients compared with healthy controls. Healthcare professionals should be aware of the association between these pathological entities to provide patients with high-quality care through an effective and holistic diagnostic and therapeutic approach.

Conventional Versus Minimally Invasive Veneers: A Systematic Review

This systematic review aimed to synthesize and analyze a collection of studies focused on comparing conventional veneers (CVs) and minimal or no-preparation veneers (MPVs) within the domain of prosthodontics. The review sought to explore various attributes, techniques, outcomes, and considerations associated with these two approaches. The key aspects investigated included esthetics, longevity, periodontal health, patient satisfaction, structural influences such as microleakage and marginal fit, cement thickness, and color stability. A systematic literature search was conducted to identify relevant studies published up to the present date. Studies meeting specific inclusion and exclusion criteria were selected for review. Studies pertaining to various methodologies were identified initially as part of the strategy and bias assessment was performed to determine the credibility of their assessments before inclusion in this review. Four comparative assessments gleaned from the selected studies provided a comprehensive overview of the strengths and limitations associated with CVs and MPVs. MPVs demonstrated advantages such as enhanced survival rates and extended mean success periods, implying their potential as viable long-term restorative options. Meticulous patient management and optimal preparation techniques emerged as crucial factors influencing successful outcomes. Structural attributes, including microleakage and marginal fit, varied depending on the preparation techniques employed. Moreover, considerations related to color changes in veneers underscored the intricate interplay between material properties and fabrication methods. The insights underscore the significance of patient-centric care, precision preparation methodologies, and material choices in guiding successful outcomes. However, the diverse methodologies and constraints of certain studies warrant careful interpretation. This study accentuates the potential for future research directions, interdisciplinary collaboration, and the advancement of evidence-based practices within veneer dentistry.

Efficacy of Nasal Floor Augmentation on the Survival Rate of Dental Implants: A Systematic Review

Aim

To systematically review the existing scientific literature, to summarize and assess the efficacy of the nasal floor augmentation on the survival rate of dental implants by systematically reviewing the available literature.

Methodology

Review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and registered in PROSPERO-CRD42027289143. Electronic databases like PubMed, google scholar and Ebsco Host were searched from 2000 to December 2021 for studies reporting efficacy of nasal floor augmentation and reporting outcomes in terms of survival rates of dental implants. Quality assessment of included comparative follow-up studies was done using the critical checklist put forward by the Joanna Briggs Institute (JBI) was used.

Results

Only nine studies fulfilled the eligibility criteria and were included in the qualitative synthesis. Of those nine studies, five were case reports and four comparative follow-up studies. A total of 14 implants were placed in five patients with a survival rate of 100% in included case reports, while a total of 408 implants were placed in 130 patients with survival rates ranging from 89% to 100% in included comparative follow-up studies. No complications were observed during follow-ups, and the patients were satisfied with the functional and aesthetic results of the treatment. Quality assessment of included studies showed moderate to low risk of bias with overall high quality of studies.

Conclusion

The results of this systematic review indicate that implant placement by nasal floor augmentation techniques can be considered as a predictable treatment modality. However, due to the scarcity of literature, more studies should be carried out on proving the efficacy of nasal floor augmentation on survival rate or success of dental Implants.

Meta-analysis and open-source database for in vivo brain Magnetic Resonance spectroscopy in health and disease

Proton (1H) Magnetic Resonance Spectroscopy (MRS) is a non-invasive tool capable of quantifying brain metabolite concentrations in vivo. Prioritization of standardization and accessibility in the field has led to the development of universal pulse sequences, methodological consensus recommendations, and the development of open-source analysis software packages. One on-going challenge is methodological validation with ground-truth data. As ground-truths are rarely available for in vivo measurements, data simulations have become an important tool. The diverse literature of metabolite measurements has made it challenging to define ranges to be used within simulations. Especially for the development of deep learning and machine learning algorithms, simulations must be able to produce accurate spectra capturing all the nuances of in vivo data. Therefore, we sought to determine the physiological ranges and relaxation rates of brain metabolites which can be used both in data simulations and as reference estimates. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we've identified relevant MRS research articles and created an open-source database containing methods, results, and other article information as a resource. Using this database, expectation values and ranges for metabolite concentrations and T2 relaxation times are established based upon a meta-analyses of healthy and diseased brains.

Repurposing drugs targeting metabolic diseases for cancer therapeutics

Hurdles in the identification of new drugs for cancer treatment have made drug repurposing an increasingly appealing alternative. The approach involves the use of old drugs for new therapeutic purposes. It is cost-effective and facilitates rapid clinical translation. Given that cancer is also considered a metabolic disease, drugs for metabolic disorders are being actively repurposed for cancer therapeutics. In this review, we discuss the repurposing of such drugs approved for two major metabolic diseases, diabetes and cardiovascular disease (CVD), which have shown potential as anti-cancer treatment. We also highlight the current understanding of the cancer signaling pathways that these drugs target.

Efficacy and Safety of Vaccinations in Geriatric Patients: A Literature Review

With the progressive lengthening of the average age of the population, especially in some countries such as Italy, vaccination of the elderly is a fixed point on which most of the public health efforts are concentrating as epidemic infectious diseases, especially those of the winter, have a major impact on the progression of severe disease, hospitalization, and death. The protection of the elderly against acute infectious diseases should not only limit mortality but also have a positive impact on the fragility of these people in terms of less disability and fewer care needs. However, vaccination of the elderly population differs in efficacy and safety compared to that of other population categories since aging and the consequent loss of efficiency of the immune system lead to a reduction in the immunogenicity of vaccines without achieving a lasting antibody coverage. There are various strategies to avoid the failure of immunization by vaccines such as resorting to supplementary doses with adjuvant vaccines, increasing the dosage of the antigen used, or choosing to inoculate the serum relying on various routes of administration of the vaccine. Vaccination in the elderly is also an important factor in light of growing antibiotic resistance because it can indirectly contribute to combating antibiotic resistance, reducing theoretically the use of those agents. Furthermore, vaccination in old age reduces mortality from infectious diseases preventable with vaccines and reduces the same rate of resistance to antibiotics. Given the importance and complexity of the topic, in this review, we will deal with the main aspects of vaccination in the elderly and how it can influence mortality and healthcare costs, especially in those countries where population aging is more evident. Therefore, we conducted a systematic literature search in PubMed to identify all types of studies published up to 31 May 2023 that examined the association between vaccination and the elderly. Data extraction and quality assessment were conducted by two reviewers (PC and TC) who independently extracted the following data and assessed the quality of each study.

Role of adjunctive nonpharmacological strategies for treatment of rapid-cycling bipolar disorder

Rapid-cycling bipolar disorder (RCBD) is a phase of bipolar disorder defined by the presence of ≥ 4 mood episodes in a year. It is a common phenomenon characterized by greater severity, a predominance of depression, higher levels of disability, and poorer overall outcomes. It is resistant to treatment by conventional pharmacotherapy. The existing literature underlines the scarcity of evi-dence and the gaps in knowledge about the optimal treatment strategies for RCBD. However, most reviews have considered only pharmacological treatment options for RCBD. Given the treatment-refractory nature of RCBD, nonpharmacological interventions could augment medications but have not been adequately examined. This review carried out an updated and comprehensive search for evidence regarding the role of nonpharmacological therapies as adjuncts to medications in RCBD. We identified 83 reviews and meta-analyses concerning the treatment of RCBD. Additionally, we found 42 reports on adjunctive nonpharmacological treatments in RCBD. Most of the evidence favoured concomitant electroconvulsive therapy as an acute and maintenance treatment. There was pre-liminary evidence to suggest that chronotherapeutic treatments can provide better outcomes when combined with medications. The research on adjunctive psychotherapy was particularly scarce but suggested that psychoeducation, cognitive behavioural therapy, family interventions, and supportive psychotherapy may be helpful. The overall quality of evidence was poor and suffered from several methodological shortcomings. There is a need for more methodologically sound research in this area, although clinicians can use the existing evidence to select and individualize nonpharmacological treatment options for better management of RCBD. Patient summaries are included to highlight some of the issues concerning the implementation of adjunctive nonpharmacological treatments.

The effectiveness of treatment with probiotics in Helicobacter pylori eradication: results from an umbrella meta-analysis on meta-analyses of randomized controlled trials

Background and aims: The purpose of this umbrella meta-analysis was to quantitatively summarize meta-analyses of randomized controlled trial (RCT) studies regarding the effects of probiotic supplementation on Helicobacter pylori (H. pylori) eradication. Methods: A thorough search of the electronic databases including PubMed, Web of Science, Embase, Scopus, and Google Scholar was carried out from the inception up to May 2022. For the evaluation of overall effect sizes, the pooled relative risk (RR) or odds ratio (OR) and their corresponding 95% confidence intervals (CI) were calculated. The random-effects model was used for the meta-analysis. Results: Overall, 18 eligible studies (47 278 participants in total) were included in the study. The findings revealed that probiotics have a beneficial impact on H. pylori eradication (pooled ESRR: 1.13; 95% CI: 1.11, 1.14, p < 0.01, and ESOR = 1.86, 95% CI: 1.70, 2.03, p < 0.01). Greater effects on H. pylori eradication were observed when higher doses (>10 × 1010 CFU) and mixed strains were supplemented. Conclusion: The present umbrella meta-analysis suggests that supplementation with probiotics may be considered as an efficient approach to ameliorate H. pylori complications, particularly probiotics with higher CFUs and mixed strains.

Short- and long-term outcomes of single-port versus multiport laparoscopic radical gastrectomy for gastric cancer: a meta-analysis of propensity score-matched studies and randomized controlled trials

BACKGROUND

At present, there is no convincing evidence-based medical basis for the efficacy of single-port laparoscopic gastrectomy. To make a high-quality comparison of the short- and long-term outcomes of single-port laparoscopic gastrectomy versus multiport laparoscopic gastrectomy, we performed this meta-analysis, which only included propensity score-matched studies and randomized controlled trials comparing single-port laparoscopic gastrectomy with multiport laparoscopic gastrectomy for patients with gastric cancer.

METHODS

Data were retrieved from the electronic databases PubMed, EMBASE, Medline, Cochrane Library, CNKI, Wanfang and VIP up to January 2023, and the data included the outcomes of treatment after single-port laparoscopic gastrectomy and multiport laparoscopic gastrectomy. The primary outcomes were early complications, survival rate after surgery at 1 year, and survival rate after surgery at 5 years. The secondary outcomes were number of pain medications, mean operation time, estimated blood loss, hospital mortality, time to first soft fluid diet, time to first flatus, hospital stay after surgery, and retrieved number of lymph nodes. The Jadad score and Newcastle‒Ottawa scale were used to assess the quality of the included studies.

RESULTS

After screening, 9 studies were finally included, including 988 patients. The meta-analysis results showed that estimated blood loss (MD=-29.35, 95% CI: -42.95-15.75, P < 0.0001), hospital stay (MD=-0.99, 95% CI:-1.82~-0.17, P = 0.02), and number of pain medications(MD=-0.65, 95% CI:-1.07~-0.23, P = 0.002) in the single-port laparoscopic gastrectomy group were better than those in the multiport laparoscopic gastrectomy group. There is no significant difference between the single-port laparoscopic gastrectomy group and the multiport laparoscopic gastrectomy group in mean operation time(MD = 5.23,95% CI:-16.58~27.04,P = 0.64), time to first soft fluid diet(MD=-0.06,95% CI: -0.30~0.18,P = 0.63), time to first flatus(MD=-0.18,95% CI:-0.43~0.07,P = 0.16), early complication(OR = 0.73,95% CI:0.50~1.09,P = 0.12), hospital mortality(OR = 1.00,95% CI:0.09~11.16,P = 1.00), retrieved number of lymph nodes(MD=-1.15, 95% CI:-2.71~0.40, P = 0.15), survival rate after surgery 1 year(OR = 2.14,95% CI:0.50~9.07,P = 0.30), and survival rate after surgery 5 year(93.7 vs. 87.6%; p = 0.689).

CONCLUSION

This meta-analysis showed that single-port laparoscopic gastrectomy is both safe and feasible for laparoscopic radical gastrectomy for gastric cancer, with similar operation times and better short-term outcomes than multiport laparoscopic gastrectomy in terms of hospital stay, postoperative pain, and estimated blood loss. There was no significant difference in long-term outcomes between single-port laparoscopic gastrectomy and multiport laparoscopic gastrectomy.

Comparing surgical outcomes of anterior capsular release vs circumferential release for persistent capsular stiffness

Purpose

To consolidate the existing literature evaluating anterior capsular release and circumferential capsular release in the treatment of adhesive capsulitis (AC) of the shoulder.

Methods

The electronic databases PUBMED, EMBASE, MEDLINE and CENTRAL (Cochrane Central Register of Controlled Trials) were searched from data inception to October 8, 2020. Data are presented descriptively where appropriate. A meta-analysis was conducted for patient-reported outcomes.

Results

Overall, there were forty-six articles included. The majority of patients underwent circumferential release compared to anterior release (80.1% vs. 19.9%). Concomitant Manipulation Under Anesthesia (MUA) was employed in 25 studies, with a higher occurrence in the anterior compared to the circumferential release group (70% vs 60%). Both groups experienced significant improvements postoperatively in range of motion (ROM) and patient-reported outcomes. Complication rates were low for both anterior release (0.67%) and 360° release (0.44%).

Conclusion

Both anterior and circumferential release are effective techniques for treating AC with low complication rates. Future studies should improve documentation of patient demographics, surgical techniques and outcomes to determine an individualized treatment protocol for patients.

Incidence of long COVID-19 in people with previous SARS-Cov2 infection: a systematic review and meta-analysis of 120,970 patients

The long-term consequences of the coronavirus disease 19 (COVID-19) are likely to be frequent but results hitherto are inconclusive. Therefore, we aimed to define the incidence of long-term COVID signs and symptoms as defined by the World Health Organization, using a systematic review and meta-analysis of observational studies. A systematic search in several databases was carried out up to 12 January 2022 for observational studies reporting the cumulative incidence of long COVID signs and symptoms divided according to body systems affected. Data are reported as incidence and 95% confidence intervals (CIs). Several sensitivity and meta-regression analyses were performed. Among 11,162 papers initially screened, 196 were included, consisting of 120,970 participants (mean age: 52.3 years; 48.8% females) who were followed-up for a median of six months. The incidence of any long COVID symptomatology was 56.9% (95% CI 52.2-61.6). General long COVID signs and symptoms were the most frequent (incidence of 31%) and digestive issues the least frequent (7.7%). The presence of any neurological, general and cardiovascular long COVID symptomatology was most frequent in females. Higher mean age was associated with higher incidence of psychiatric, respiratory, general, digestive and skin conditions. The incidence of long COVID symptomatology was different according to continent and follow-up length. Long COVID is a common condition in patients who have been infected with SARS-CoV-2, regardless of the severity of the acute illness, indicating the need for more cohort studies on this topic.

Prevalence of COVID-19 vaccine acceptance among migrant and refugee groups: A systematic review and meta-analysis

Objectives

Understanding COVID-19 vaccine hesitancy among migrant and refugee groups is critical for achieving vaccine equity. Therefore, we aimed to estimate the prevalence of COVID-19 vaccine acceptance among migrant and refugee populations.

Methods

A systematic review (PROSPERO: CRD42022333337) was conducted (December 2019-July 2022) using PubMed, Scopus, Web of Science, ProQuest and Google Scholar.

Results

Nineteen studies from 12 countries were included. The pooled estimated prevalence of COVID-19 vaccine willingness among migrant and refugee groups was 70% (19 studies, 95% CI: 62.3-77.4%, I2: 99.19%, τ2: 0.03). Female and male participants did not differ significantly with each other (p = 0.64). Although no individual variable contributed statistically significantly in multivariable meta-regression analysis, the multivariable model that considered methodological quality, mean age of participants, participant group and country of origin explained 67% of variance.

Discussion

Proportions of migrant/refugee groups receiving COVID-19 vaccinations approximated those observed among general populations. Additional studies are needed to examine factors relating to vaccine willingness to identify the most significant factors that may be targeted in interventions.

Respiratory Management of Patients With Neuromuscular Weakness: An American College of Chest Physicians Clinical Practice Guideline and Expert Panel Report

BACKGROUND

Respiratory failure is a significant concern in neuromuscular diseases (NMDs). This CHEST guideline examines the literature on the respiratory management of patients with NMD to provide evidence-based recommendations.

STUDY DESIGN AND METHODS

An expert panel conducted a systematic review addressing the respiratory management of NMD and applied the Grading of Recommendations, Assessment, Development, and Evaluations approach for assessing the certainty of the evidence and formulating and grading recommendations. A modified Delphi technique was used to reach a consensus on the recommendations.

RESULTS

Based on 128 studies, the panel generated 15 graded recommendations, one good practice statement, and one consensus-based statement.

INTERPRETATION

Evidence of best practices for respiratory management in NMD is limited and is based primarily on observational data in amyotrophic lateral sclerosis. The panel found that pulmonary function testing every 6 months may be beneficial and may be used to initiate noninvasive ventilation (NIV) when clinically indicated. An individualized approach to NIV settings may benefit patients with chronic respiratory failure and sleep-disordered breathing related to NMD. When resources allow, polysomnography or overnight oximetry can help to guide the initiation of NIV. The panel provided guidelines for mouthpiece ventilation, transition to home mechanical ventilation, salivary secretion management, and airway clearance therapies. The guideline panel emphasizes that NMD pathologic characteristics represent a diverse group of disorders with differing rates of decline in lung function. The clinician's role is to add evaluation at the bedside to shared decision-making with patients and families, including respect for patient preferences and treatment goals, considerations of quality of life, and appropriate use of available resources in decision-making.

Prevalence of Electrolyte Imbalance in Patients With Acute Stroke: A Systematic Review

Electrolyte abnormalities are common in acute stroke patients and have a substantial impact on the course and prognosis of the disease. Electrolyte imbalances such as hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia, and phosphate abnormalities are frequently seen in this patient population. The incidence, root causes, and medical ramifications of electrolyte abnormalities in acute stroke patients are investigated in this comprehensive study. According to our research, hyponatremia is the most prevalent electrolyte imbalance. The most common reason for hyponatremia in stroke patients is the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Higher mortality rates, longer hospital admissions, and less favorable functional outcomes are all linked to hyponatremia. Acute stroke patients also typically experience hypokalemia, which affects the severity of the stroke and the recovery of functional abilities. The review furthermore emphasizes the incidence and clinical consequences of hypercalcemia, hypomagnesemia, hypophosphatemia, and hypocalcemia in patients with acute stroke. The results highlight the significance of early electrolyte imbalance detection and treatment in acute stroke patients. To better comprehend therapeutic approaches, evaluate their influence on stroke outcomes, and analyze prognostic implications, more research is required.

Precarious employment and associated health and social consequences; a systematic review

OBJECTIVE

This systematic review aims to identify, evaluate, and summarise the consequences of precarious employment.

METHODS

We included studies published within the last ten years (Jan 2011-July 2021) that employed at least two of three key dimensions of precarious employment: employment insecurity, income inadequacy, and lack of rights and protection.

RESULTS

Of the 4,947 initially identified studies, only five studies met our eligibility criteria. These five studies were of moderate quality as assessed by the Newcastle-Ottawa Scale. Our review found that the current literature predominantly defines precarity based on the single criterion of employment insecurity. Our review identified evidence for the negative consequences of precarious employment, including poorer workplace wellbeing, general health, mental health, and emotional wellbeing. The findings indicated an increase in the magnitude of these adverse outcomes with a higher degree of job precariousness.

CONCLUSIONS

The rise of employment precariousness will likely continue to be a major issue in the coming years. More research is needed to inform effective policies and practices using a consensus definition of precarious employment.

IMPLICATIONS FOR PUBLIC HEALTH

The presence of adverse effects of precarious employment suggests workplace initiatives are essential to mitigate the negative consequences of precarity.

Delivering substance use prevention interventions for adolescents in educational settings: A scoping review

Currently, a proportion of adolescents use alcohol, tobacco, and illicit drugs, which inevitably harms their health and academic progress. Adolescence is a peak period for substance use initiation and a critical time for preventing substance use problems. Various entities, such as families, schools, and communities, have implemented a variety of interventions to alleviate adolescent substance use problems, and schools play a unique role. To explore the types, characteristics, and effectiveness of substance use interventions in educational settings for adole-scents, we conducted a scoping review and identified 32 studies after screening. We divided the 32 studies according to intervention type, including curriculum interventions focusing on cognitive-behavioral skill enhancement, exercise interventions, peer interventions and family-school cooperation, and electronic interventions. Except for the mixed results on electronic interventions, the results showed that the other interventions were beneficial to different extents in alleviating adolescent substance use problems. In addition, we analyzed and summarized the advantages and challenges of intervening in adolescent substance use in educational settings. Schools can use equipment and human resources to provide adolescents with various types of intervention measures, but they also face challenges such as stigmatization, ineffective coordination among multiple resources, and poor implementation effects. In the future, school-based intervention measures can fully utilize big data and artificial intelligence technology and collaborate with families and communities to intervene appro-priately while paying attention to the comorbidity risks of substance use disorders and psychological health issues.

Treatment as prevention for hepatitis C virus in the Middle East and North Africa: a modeling study

Background

Direct-acting antivirals opened an opportunity for eliminating hepatitis C virus (HCV) infection in the Middle East and North Africa (MENA), the region most affected by HCV infection. Impact of HCV treatment as prevention (HCV-TasP) was investigated in 19 MENA countries.

Methods

An age-structured mathematical model was used to assess program impact using epidemiologic and programming measures. The model was fitted to a database of systematically gathered HCV antibody prevalence data. Two main scenarios were investigated for the treatment roll-out to achieve (i) 80% reduction in HCV incidence by 2030, and (ii) incidence rate < 1 per 100,000 person-years by 2030.

Results

In the target-80%-incidence-reduction scenario, number of treatments administrated by 2030 ranged from 2,610 in Lebanon to 180,416 in Sudan with a median of 53,079, and treatment coverage ranged between 40.2 and 78.4% with a median of 60.4%. By 2030, prevalence of chronic infection ranged between 0.0 and 0.3% with a median of 0.1%, and incidence rate, per 100,000 person-years, ranged between 0.9 and 16.3 with a median of 3.2. Program-attributed reduction in incidence rate ranged between 47.8 and 81.9% with a median of 68.5%, and number of averted infections ranged between 401 and 68,499 with a median of 8,703. Number of treatments needed to prevent one new infection ranged from 1.7 in Oman to 25.9 in Tunisia with a median of 6.5. In the target incidence rate  < 1 per 100,000 person-years scenario, number of treatments administrated by 2030 ranged from 3,470 in Lebanon to 211,912 in Sudan with a median of 54,479, and treatment coverage ranged between 55.5 and 95.9% with a median of 87.5%. By 2030, prevalence of chronic infection was less than 0.1%, and incidence rate, per 100,000 person-years, reached less than 1. Program-attributed reduction in incidence rate ranged between 61.0 and 97.5% with a median of 90.7%, and number of averted infections ranged between 559 and 104,315 with a median of 12,158. Number of treatments needed to prevent one new infection ranged from 1.3 in Oman to 25.9 in Tunisia with a median of 5.5.

Conclusion

HCV-TasP is an effective and indispensable prevention intervention to control MENA's HCV epidemic and to achieve elimination by 2030.

Body Composition and Risk of Incident Heart Failure in 1 Million Adults: A Systematic Review and Dose-Response Meta-Analysis of Prospective Cohort Studies

Background The aim of this systematic review was to quantify the associations between body composition measures and risk of incident heart failure (HF) and its subtypes in the general population. Methods and Results We searched Medline, Embase, and Global Health databases from each database inception to January 19, 2023 for prospective studies reporting on body composition and HF risk. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Newcastle-Ottawa scale was used to assess the risk of bias of included studies. Fixed-effects models were used for meta-analysis. Thirty-five studies were included (ntotal=1 137 044; ncases=34 422). Summary relative risk (RR) per 5-kg/m2 higher body mass index was 1.42 (95% CI, 1.40-1.42; 𝜁2=0.02, I2=94.4%), 1.28 (95% CI, 1.26-1.31; 𝜁2=0.01, I2=75.8%) per 10-cm higher waist circumference, and 1.33 (95% CI, 1.28-1.37; 𝜁2=0.04, I2=94.9%) per 0.1-unit higher waist-hip ratio. Pooled estimates of the few studies that reported on regional fat suggested significant positive association between HF risk and both visceral fat (RR, 1.08 [95% CI, 1.04-1.12]) and pericardial fat (RR, 1.08 [95% CI, 1.06-1.10]). Among HF subtypes, associations were stronger for HF with preserved ejection fraction than HF with reduced ejection fraction. No study reported on lean mass. Conclusions Pooled data suggested strong associations between adiposity and HF. The association with adiposity is stronger for HF with preserved ejection fraction than HF with reduced ejection fraction, indicating that different mechanisms may be at play in etiopathogenesis of HF subtypes. Future studies are needed to investigate role of regional fat mass and lean mass in HF risk. Registration Information REGISTRATION: URL: www.crd.york.ac.uk/prospero/.

Pharmacokinetic, toxicological, and clinical considerations for the treatment of type 2 diabetes in patients with liver disease: a comprehensive update

INTRODUCTION

Type 2 diabetes and liver disease, mainly metabolic-associated fatty liver disease (MAFLD) and more rarely cirrhosis, coexist in many patients. This duality has direct implications for the physician when choosing glucose-lowering agents, with classical concerns but also recent new hopes.

AREAS COVERED

This updated comprehensive review will consider the pharmacokinetics, the tolerance/safety profile, the benefit/risk balance in cirrhosis, the effects on MAFLD and the risk of hepatocellular carcinoma of old and new glucose-lowering compounds in patients with liver disease, with a special focus on glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors.

EXPERT OPINION

We are currently facing a new paradigm in the management of patients with diabetes and liver disease. From previous reluctance when using antidiabetic agents (except insulin) in diabetic patients with hepatic impairment because of safety concerns, the commercialization of novel glucose-lowering agents has changed the scene. These agents, which have a good safety profile, are associated with weight loss and pleiotropic effects. They have proven their efficacy in improving MAFLD. However, more specific studies are still needed to prove their efficacy in preventing the progression to fibrosis/cirrhosis and confirm this new opportunity for the management of patients with diabetes and liver disease.

NICU sensory experiences associated with positive outcomes: an integrative review of evidence from 2015-2020

To inform changes to the Supporting and Enhancing NICU Sensory Experiences (SENSE) program, studies investigating sensory-based interventions in the NICU with preterm infants born ≤32 weeks were identified. Studies published between October 2015 to December 2020, and with outcomes related to infant development or parent well-being, were included in this integrative review. The systematic search used databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and Google Scholar. Fifty-seven articles (15 tactile, 9 auditory, 5 visual, 1 gustatory/olfactory, 5 kinesthetic, and 22 multimodal) were identified. The majority of the sensory interventions that were identified within the articles were reported in a previous integrative review (1995-2015) and already included in the SENSE program. New evidence has led to refinements of the SENSE program, notably the addition of position changes across postmenstrual age (PMA) and visual tracking starting at 34 weeks PMA.

Efficacy of implantoplasty in management of peri-implantitis: A systematic review

Aim

Peri-implantitis causes progressive loss of the supporting bony structure around the dental implant. Implantoplasty mechanically removes contaminated threads to achieve smoother implant surface thus reducing the bacterial load enabling fibroblastic growth to stimulate the healing effect. This Systematic review is done to appraise the outcome of implantoplasty on surface quality of Implant (roughness), biocompatibility of implants in peri-implantitis cases.

Settings and Design

The Settings of the studies are major online databases like PubMed, Scopus, and Cochrane online library. The design of the current study is systematic review of published qualitative studies.

Materials and Method

37 articles were identified for the present review and systematic electronic literature search was done from August 2022 to January 2023, via PubMed, Scopus, Medline, and The Cochrane Library (Wiley) databases [PRISMA guidelines]. In vitro studies on implantoplasty for peri-implantitis were included for the review. 2 examiners independently selected based on the inclusion criteria and recorded the necessary data.

Statistical Analysis Used

Risk of bias assessment tool was evaluated with Newcastle Ottawa scale (NOS) and screened based on Selection, Comparability, and Outcome with the following categories: - maximum of 4, 2 and 4 points respectively. The observations were tabulated and analysed.

Results

Among the 8 selected studies, two studies reported no statistical difference between implantoplasty and control, one study proposed carbide burs were better than diamond burs, another study also suggested multilaminar burs were better than diamond and carbide. The Newcastle Ottawa scale (NOS) score for the quality of the included studies ranged from 6 to 8. Two of the studies had score of 6 points, eight had 7 points and one had 8 points.

Conclusion

Implantoplasty has been recommended as an efficacious treatment protocol for peri-implantitis that helps to diminish the inflammation and accompanied by a high success rate.

Prevalence of Anemia Among the Elderly in India: Evidence From a Systematic Review and Meta-Analysis of Cross-Sectional Studies

Anemia is a leading cause of increased morbidity and mortality among the elderly population. In spite of numerous interventions and strategies rolled out to tackle the growing burden of anemia, lesser importance is being given to this age group. There is a lack of data on the national level burden of anemia among elderly persons (≥ 60 years) in India. We aimed at estimating the prevalence of anemia among elderly persons (≥ 60 years) in India by conducting a systematic review and meta-analysis. We searched PubMed, Embase, Cochrane Library, Google Scholar, and IndMed, and included cross-sectional studies reporting data on the prevalence of anemia among elderly persons in India and used random effects model to estimate pooled point prevalence with 95% confidence interval (CI), To explore the heterogeneity further, we did sub-group analyses based on zonal divisions of India (region), rural or urban, study setting, method of hemoglobin estimation and sampling strategy. Out of 22 studies, one study was of high quality of bias, 11 of moderate, and 10 were of low quality of bias. The pooled estimate of anemia was 68.3% (95%CI: 60.7 to 75.9), I2 = 99.0%, and Q=2079.2 (p-value <0.001). The pooled prevalence of anemia among the elderly in India was found to be high and necessary actions need to be taken at the policy level to achieve "active and healthy ageing".

Oculomotor deficits in attention deficit hyperactivity disorder: a systematic review and meta-analysis

There is equivocal evidence on the presence of oculomotor deficits among children with attention deficit hyperactivity disorder (ADHD), which can be an additional challenge in this population, especially with reading-related tasks. This study aimed to review the deficits in the oculomotor parameters among children with ADHD compared with age-matched controls. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A search of original research articles on various databases was done using key terms, such as "oculomotor deficit," "attention deficit hyperactivity disorder," or related terms. We included case-control studies and excluded studies in which children received medications during the test. Twelve original research studies were considered for this review. Ten studies reported data on various types of saccades, two studies reported data on fixation, and one study reported data on pursuit. Among various oculomotor deficits, the forest-plot analysis of an antisaccade task showed that children with ADHD made more direction errors compared to controls. Although independent studies report that ADHD children have poorer performance compared to control populations during oculomotor tasks, there is a lack of evidence to draw a strong conclusion. Children with ADHD are less precise in performing eye movements and need more time to complete the oculomotor tasks than those without ADHD. The overall results provide minimal evidence regarding the presence of various oculomotor deficits in ADHD.

Is functional training an efficient approach to improve body composition in older people? A systematic review

Introduction: Increases in fat mass and reductions in lean mass are associated with the frailty and mortality of older people. In this context, Functional Training (FT) is an option to increase lean mass and reduce fat mass in older people. Thus, this systematic review aims to investigate the effects of FT on body fat and lean mass in older people. Methods: We included randomized controlled clinical trials, with at least one intervention group that employed FT, with the age of participants ≥60 years; and participants physically independent and healthy. We performed the systematic investigation in Pubmed MEDLINE, Scopus, Web of Science, Cochrane Library, and Google Scholar. We extracted the information and used the PEDro Scale to assess the methodological quality of each study. Results: Our research found 3,056 references with five appropriate studies. Of the five studies, three presented reductions in fat mass, all of them with interventions between three and 6 months, different training dose parameters, and 100% of the sample was composed of women. On the other hand, two studies with interventions between 10 and 12 weeks presented conflicting results. Conclusion: Despite the limited literature about lean mass, it appears that long-term FT interventions may reduce fat mass in older women.

Evidence relating cigarette, cigar and pipe smoking to lung cancer and chronic obstructive pulmonary disease: Meta-analysis of recent data from three regions

BACKGROUND

There is a need to have up-to-date information for various diseases on the risk related to the use of different smoked products and the use of other nicotine-containing products. Here, we contribute to the information pool by presenting up-to-date quantitative evidence for North America, Europe and Japan and for both lung cancer and chronic obstructive pulmonary disease (COPD) on the relative risk (RR) relating to current vs never product use for each of the three smoked tobacco products, cigarettes, cigars and pipes.

AIM

To estimate lung cancer and COPD current smoking RRs for the three products using recent data for the three regions.

METHODS

Publications in English from 2010 to 2020 were considered that, based on epidemiological studies in the three regions, estimated the current smoking RR of lung cancer and/or COPD for one or more of the three products. The studies should involve at least 100 cases of the disease considered, not be restricted to specific lung cancer types or populations with specific medical conditions, and should be of cohort or nested case-control study design or randomized controlled trials. Literature searches were conducted on MEDLINE separately for lung cancer and for COPD, examining titles and abstracts initially, and then full texts. Additional papers were sought from reference lists of selected papers, reviews and meta-analyses. For each study identified, the most recent available data on each product were entered on current smoking, as well as on characteristics of the study and the RR estimates. Combined RR estimates were derived using random-effects meta-analysis. For cigarette smoking, where far more data were available, heterogeneity was studied by a wide range of factors. For cigar and pipe smoking, a more limited heterogeneity analysis was carried out. Results were compared with those from previous meta-analyses published since 2000.

RESULTS

Current cigarette smoking: For lung cancer, 44 studies (26 North American, 14 European, three Japanese, and one in multiple continents), gave an overall estimate of 12.14 [95% confidence interval (CI) 10.30-14.30]. The estimates were higher (heterogeneity P < 0.001) for North American (15.15, CI 12.77-17.96) and European studies (12.30, CI 9.77-15.49) than for Japanese studies (3.61, CI 2.87-4.55), consistent with previous evidence of lower RRs for Asia. RRs were higher (P < 0.05) for death (14.85, CI 11.99-18.38) than diagnosis (10.82, CI 8.61-13.60). There was some variation (P < 0.05) by study population, with higher RRs for international and regional studies than for national studies and studies of specific populations. RRs were higher in males, as previously reported, the within-study male/female ratio of RRs being 1.52 (CI 1.20-1.92). RRs did not vary significantly (P ≥ 0.05) by other factors. For COPD, RR estimates were provided by 18 studies (10 North American, seven European, and one Japanese). The overall estimate of 9.19 (CI 6.97-12.13), was based on heterogeneous data (P < 0.001), and higher than reported earlier. There was no (P > 0.1) variation by sex, region or exclusive use, but limited evidence (0.05 < P < 0.1) that RR estimates were greater where cases occurring shortly after baseline were ignored; where bronchiectasis was excluded from the COPD definition; and with greater confounder adjustment. Within-study comparisons showed adjusted RRs exceeded unadjusted RRs. Current cigar smoking: Three studies gave an overall lung cancer RR of 2.73 (CI 2.36-3.15), with no heterogeneity, lower than the 4.67 (CI 3.49-6.25) reported in an earlier review. Only one study gave COPD results, the RR (2.44, CI 0.98-6.05) being imprecise. Current pipe smoking: Four studies gave an overall lung cancer RR of 4.93 (CI 1.97-12.32), close to the 5.20 (CI 3.50-7.73) given earlier. However, the estimates were heterogeneous, with two above 10, and two below 3. Only one study gave COPD results, the RR (1.12, CI 0.29-4.40), being imprecise. For both diseases, the lower RR estimates for cigars and for pipes than for current smoking of cigarettes aligns with earlier published evidence.

CONCLUSION

Current cigarette smoking substantially increases lung cancer and COPD risk, more so in North America and Europe than Japan. Limited evidence confirms lower risks for cigars and pipes than cigarettes.

Meta-analysis and Open-source Database for In Vivo Brain Magnetic Resonance Spectroscopy in Health and Disease

Proton ( 1 H) Magnetic Resonance Spectroscopy (MRS) is a non-invasive tool capable of quantifying brain metabolite concentrations in vivo . Prioritization of standardization and accessibility in the field has led to the development of universal pulse sequences, methodological consensus recommendations, and the development of open-source analysis software packages. One on-going challenge is methodological validation with ground-truth data. As ground-truths are rarely available for in vivo measurements, data simulations have become an important tool. The diverse literature of metabolite measurements has made it challenging to define ranges to be used within simulations. Especially for the development of deep learning and machine learning algorithms, simulations must be able to produce accurate spectra capturing all the nuances of in vivo data. Therefore, we sought to determine the physiological ranges and relaxation rates of brain metabolites which can be used both in data simulations and as reference estimates. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we've identified relevant MRS research articles and created an open-source database containing methods, results, and other article information as a resource. Using this database, expectation values and ranges for metabolite concentrations and T 2 relaxation times are established based upon a meta-analyses of healthy and diseased brains.

Epidemiology of Patellar Tendinopathy in Athletes and the General Population: A Systematic Review and Meta-analysis

Background

Patellar tendinopathy (PT) mainly affects athletes who use the tendon for repeated energy storage and release activities. It can have a striking impact on athletes' careers, although data on its real prevalence and incidence are sparse. Research efforts should start from the results of reliable and updated epidemiological research to help better understand the impact of PT and underpin preventative measures.

Purpose

To determine the prevalence and incidence of PT in athletes and the general population.

Design

Systematic review; Level of evidence, 3.

Methods

A systematic review of the literature was performed on January 17, 2022, and conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed, Web of Science, and Wiley Cochrane Library databases were searched for epidemiological reports of any evidence level and clinical studies reporting data on the incidence or prevalence of PT for the 11,488 retrieved records. The primary endpoint was the prevalence and incidence of PT in sport-active patients. The secondary endpoints were PT prevalence and incidence in subgroups of athletes based on sex, age, sport type, and sport level played, as well as the same epidemiological measures in the general population.

Results

A total of 28 studies, with 28,171 participants, were selected and used for the qualitative and quantitative analysis. The general and athletes' populations reported an overall PT prevalence of 0.1% and 18.3%, respectively. In athletes, the prevalence of PT was 11.2% in women and 17% in men (P = .070). The prevalence of PT in athletes <18 years was 10.1%, while it was 21.3% in athletes ≥18 years (P = .004). The prevalence of PT was 6.1% in soccer players, 20.8% in basketball players, and 24.8% in volleyball players. Heterogeneous PT diagnostic approaches were observed. Higher prevalence values were found when PT diagnoses were made using patient-reported outcomes versus clinical evaluations (P = .004).

Conclusion

This review demonstrated that PT is a common problem in the male and female sport-active populations. There are twice as many athletes aged ≥18 years than there are <18 years. Volleyball and basketball players are most affected by PT.
