Correspondence to: Estimating the full health and economic benefits of current and future influenza vaccines

We recently published an article in BMC Medicine looking at the potential health and economic impact of paediatric vaccination using next-generation influenza vaccines in Kenya: a modelling study. In their commentary on our article, Lafond et al. highlight the potential importance of the wider benefits of vaccination on cost-effectiveness. Whilst we agree with many points raised in the commentary, we think it raises further interesting discussion points, specifically around model complexity, model assumptions and data availability. These points are both relevant to this manuscript but have wider implications for vaccine cost-effectiveness studies.

Burden of care and coping strategies among informal caregivers of people with behavioral and psychological symptoms of dementia in rural south-western Uganda

BACKGROUND

Caregiving is a draining role that inflicts a significant level of burden upon caregivers for older people with Behavioral and Psychological Symptoms of Dementia (BPSD). Caregiver burden is associated with poor health outcomes for both the people with BPSD and their caregivers. This study explored the burden of care and coping strategies used by informal caregivers of older people with BPSD in rural Southwestern Uganda.

METHODS

This was a qualitative study among informal caregivers of older people with BPSD in Rubanda and Rukiga districts. We conducted in-depth interviews with a purposive sample of 27 caregivers using an interview guide. The interviews were conducted in the local language, audio recorded, transcribed, translated into English, and thematically analyzed.

RESULTS

There were two major themes: caregiver burden and coping strategies. Caregiver burden was described as financial, physical, psychological and social. Caregivers mainly used emotion-focused coping strategies (religious coping, acceptance and emotional support seeking). Problem-focused coping strategies (planning) and dysfunctional coping strategies (self-distraction) were used to a lesser extent.

CONCLUSION

Informal caregivers of people with BPSD adopted both emotional and problem-focused coping strategies to cope with the burden of care for people with BPSD. Such coping strategies seemed to lighten the burden of caring, in the long motivating the caregivers to continue with the caring role.

A cross-sectional study exploring the positive aspects of caregiving in opioid dependence and its relation with quality of life, social support, and caregivers' burden

Background and Aims

Despite a large body of research linking caregiver burden and social support in substance dependence, positive aspects of caregiving in these disorders have received very minimal attention. This exploratory observational study aimed to assess the positive aspects of caregiving for opioid dependence and evaluate the association of these positive aspects with caregiver quality of life, burden, and social support.

Methods

This cross-sectional study included 199 caregivers of patients with opioid dependence recruited through purposive sampling. Participants were assessed using the Scale for Positive Aspects of Caregiving Experience (SPACE), World Health Organization Quality of Life-BREF version, Family Burden Interview Schedule (FBIS), and Social Support Questionnaire.

Results

Of the 199 caregivers recruited, a majority of the caregivers were middle-aged women. About two-thirds of the patients were currently using opioids (n = 135, 67.8%), while the remaining were abstinent. Among the SPACE domain scores, the mean was highest for motivation for the caregiving role (2.07), which was followed by self-esteem and social aspect of caring (2.04), caregiving personal gains (1.76), and caregiver satisfaction (1.65). Caregivers of patients currently abstinent experienced greater positive aspects of caregiving (SPACE mean item score 2.57 versus 1.62, P < 0.001), and lesser burden (FBIS mean score 13.4 versus 29.3, P < 0.001).

Conclusion

Positive aspects of caregiving can be potentially utilized for better caregiver engagement in treatment and improved caregiver outcomes.

Potential impact of rotavirus vaccination on reduction of childhood diarrheal disease in India: An analysis of National Family Health Survey-5

Rotavirus is one of the leading causes of diarrhea in infants and young children worldwide. In this study, we investigated the impact of rotavirus vaccination on the prevalence of diarrheal disease among children under five years of age in India. Research on the impact of the rotavirus vaccine on reducing diarrheal disease is therefore important in contributing to the growing body of evidence on the effectiveness of this intervention in improving child health outcomes. We adopted multivariate logistic regression and propensity score matching analysis to examine the association between diarrhea and the rotavirus vaccine. The bivariate analysis finding shows that the prevalence of diarrhea was remarkably higher (9.1%) among children who had not received rotavirus and the prevalence was 7.5%, 7.5%, and 7.2% among children who received one dose, two doses, and three rotavirus doses (all) respectively. The result of multivariate logistic regression shows that children who received all three doses of the rotavirus vaccine were 16% less likely to experience diarrhea compared to those who did not receive any rotavirus vaccine. Our analysis also found that the prevalence of diarrhea decreased significantly in the years following the introduction of the vaccine. The results of this study suggest that the rotavirus vaccine has a significant impact on reducing childhood diarrheal disease in India. These results have the potential to inform policy decisions and enable healthcare professionals to concert their efforts in reducing the diarrheal disease burden and its timely prevention in children. The study will also contribute to the existing literature on the impact of rotavirus vaccination in reducing the prevalence of diarrhea among children in India.

Estimated projection of incidence and mortality of alcohol-related liver disease in China from 2022 to 2040: a modeling study

BACKGROUND

China has one of the highest numbers of liver disease cases in the world, including 6.4 million cirrhosis associated with alcohol-related liver disease (ALD) cases. However, there is still a lack of urgent awareness about the growth of alcohol consumption and the increased burden of ALD in China. Therefore, we aimed to project the potential impact of changes in alcohol consumption on the burden of ALD in China up to 2040 under different scenarios.

METHODS

We developed a Markov model to simulate the natural history of ALD until 2040 in China. We estimated the incidence and mortality of alcohol-related cirrhosis and hepatocellular carcinoma between 2022 and 2040 under four projected scenarios: status quo scenario and scenarios with a 2%, 4%, and 8% annual decrease in excessive alcohol consumption, respectively.

RESULTS

Under the status quo scenario, the cumulative new cases of cirrhosis from 2022 to 2040 was projected to be 3.61 million (95% UI 3.03-4.44 million), resulting in a cumulative 1.96 million (1.66-2.32 million) deaths from alcohol-related cirrhosis and hepatocellular carcinoma. However, a 2% annual reduction in excessive alcohol consumption was expected to avert 0.3 million deaths associated with ALD, and a 4% annual reduction was projected to prevent about 1.36 million new cases of cirrhosis and prevent 0.5 million ALD-related deaths. Moreover, an 8% annual reduction would prevent about 2 million new cases of cirrhosis and 0.82 million deaths.

CONCLUSIONS

Without any substantial change in alcohol attitudes and policies to regulate excessive drinking, the disease burden of ALD in China will increase enormously. Strengthening the implementation of alcohol restriction interventions is critical and urgent to reduce the impact of ALD on the Chinese population.

A scoping review of intensive longitudinal methods in informal caregivers of people with dementia

BACKGROUND

The daily life of informal caregivers assisting individuals with dementia widely varies throughout the day and week. As an answer, an increasing number of researchers have used intensive longitudinal methods (ILMs) such as diary studies, experience sampling methods, or ecological momentary assessment.

OBJECTIVES AND METHODS

The present scoping review aims at synthesizing the use of ILMs in informal dementia caregivers to clarify what is currently done and how, as well as what remains unaddressed.

RESULTS

The screening process identified 48 studies from 22 different datasets. Synthesis of these studies showed the diversity of devices and uses of ILMs in informal care, including the exploration of associations between variables or accompanying an intervention. ILMs showed the important variability of caregiving phenomena, as well as the important association of momentary stress and well-being. Gaps were nevertheless identified, such as transparency in the construction of the tool or the absence of focus on emotions and dyads.

CONCLUSIONS

For now, this field of research remains in its infancy and does not seem to have reached its full potential as it has in other fields. Nevertheless, it appears that ILMs are promising tools for informal dementia caregivers as they contribute to understanding the complexity of their daily life, with changing resources and challenges. Future directions include focusing more on (emotion) regulation, temporal lags, and the use of ILMs in interventional designs.

Protocol of a feasibility randomised controlled trial of Empowered Conversations: training family carers to enhance their relationships and communication with people living with dementia

Background

Communication difficulties can cause frustration, low mood, and stress for people living with dementia and their carer. Carers should be offered training on adapting their communication skills. However, it is not common for skills-based education to examine emotional aspects of care and the effect of dementia on relationships. The Empowered Conversations (EC) training course was developed in response to a gap in service provision and has been adapted to a virtual format (Zoom). It addresses the specific psychological, relationship, and communication needs of informal and family dementia carers. The primary aim of the study is to investigate the feasibility of conducting a multi-centre randomised controlled evaluation trial of EC. Secondary aims include exploring the acceptability of delivering the intervention online and examining the optimum way of establishing cost-effectiveness.

Methods

The feasibility trial uses a pragmatic data-collector blind parallel two-group RCT design with two arms (EC intervention plus treatment as usual, and treatment as usual waitlist control). There will be a 2:1 allocation in favour of the EC-training intervention arm. 75 participants will complete baseline outcome measures exploring their role as a carer, including their physical and mental health, attitudes to caring, quality of life, and use of health and social care services. These will be repeated after six-months. Participants allocated to the treatment group who complete the course will be invited to participate in a qualitative interview discussing their experience of EC.

Conclusions

The study will investigate recruitment pathways (including facilitators and barriers to recruitment), estimate retention levels and response rates to questionnaires, obtain additional evidence regarding proof of concept, and consider the most appropriate primary outcome measures and methods for evaluating cost-effectiveness. The results of the feasibility study will be used to inform the development of a multicentre randomised controlled trial in the United Kingdom.

Global importance of new treatment strategies to efforts to control hepatitis B virus

INTRODUCTION

Hepatitis B Virus (HBV) infection can progress to chronic HBV (CHB) disease, thereby increasing the risk of severe forms of liver disease (i.e. liver cirrhosis and hepatocellular carcinoma) and resulting in a high global burden of morbidity, mortality, and health-care utilization.

AREAS COVERED

We discuss how future therapeutic strategies and treatment guidelines may address the large unmet medical needs among patients with CHB.

EXPERT OPINION

Complexity and a lack of consensus in current CHB treatment guidelines may limit their effective implementation. To minimize poor outcomes in patients not currently receiving treatment (including immune-tolerant and inactive carriers), a simplified harmonized treatment approach is needed across guidelines. Current treatment recommendations focus on nucleot(s)ide analogs (NAs) and pegylated interferon (Peg-IFN), both of which have limitations. NAs provide clinical benefits, but treatment is prolonged and has little impact on functional cure rates. Peg-IFN offers the potential for functional cure but has notable safety and tolerability issues. A shift toward finite treatments with acceptable safety and tolerability profiles is needed.

CONCLUSION

The key to achieving World Health Organization targets for the global eradication of HBV involves enhanced diagnosis with new treatments and/or combinations of existing treatments alongside globally aligned and simplified treatment guidelines for untreated/inadequately treated populations.

Why do Mothers from Remote Rural Areas opt for Cesarean Delivery: An Observational Analytical Study from West Bengal, India

Background

The percentage of cesarean section (C-section) deliveries has doubled in the last two decades in India. Although C-section delivery is a life-saving intervention, multiple maternal and neonatal morbidities are often associated with this procedure, adversely affecting the quality of life of both the mother and child.

Material and Methods

This community-based cross-sectional study was conducted to assess the point of view of mothers who delivered from January 2020 to June 2021.

Results

The mean (standard deviation (SD)) age of the 866 study participants at delivery was 24.5 (4.8) years, and 60.2% were primigravidas. A total of 613 (70.8%; 95% CI: 67.8-73.8) C-sections were conducted, of which 65.9% (n = 404) were planned and 21.9% were done on maternal request. C-sections were significantly associated with private institutes (adjusted prevalence ratio (aPR) 1.90; 95% CI: 1.70-2.11), at-risk pregnancy (aPR 1.37; 95% CI: 1.26-1.49), and primigravida (aPR 1.16; 95% CI: 1.05-1.29). About 55.3%, 29.8%, and 14.9% of women considered vaginal delivery to be risky, painful, and inconvenient, respectively.

Conclusion

It is imperative to generate awareness regarding modes of delivery during antenatal care (ANC) so that mothers can make better-informed choices.

Healthcare and socioeconomic costs of NAFLD: A global framework to navigate the uncertainties

Left unaddressed, non-alcoholic fatty liver disease (NAFLD) will continue to have substantial health, economic and social implications. To address the challenge, a paradigm shift is needed in the way NAFLD is conceptualised. Concerted, collaborative action across medical specialities, industry sectors and governments will be vital in tackling this public health threat. To drive this change, in this review, we present data on the current global healthcare and socioeconomic costs of NAFLD and highlight priority actions. The estimated healthcare costs of patients with NAFLD are nearly twice as high as their age-matched counterparts without the disease and are highest in those with advanced fibrosis and end-stage liver disease. NAFLD is accountable for the highest increase in DALYs (disability-adjusted life years) among all liver diseases globally. NAFLD and non-alcoholic steatohepatitis (NASH)-specific drug therapies are not yet available and there is considerable uncertainty regarding cost, optimal length of treatment, and their impact on liver-related outcomes and mortality. Among the currently available bariatric procedures, sleeve gastrectomy is reported to be the most cost-effective for NASH resolution. Gastric bypass remains very expensive, while data on bariatric endoscopy are limited. Lastly, we propose a global NAFLD/NASH investment framework to guide the development of achievable yet ambitious country-specific targets and strategic actions to optimise resource allocation and reduce the prevalence of NAFLD and NASH. Its focus on high-level inputs will be critical to enabling a political and financial environment that supports clinical-level implementation of NAFLD prevention, treatment and care efforts, across all settings.

population: results from National Health and Nutrition Examination Survey, 1999-2020

Background

The phenotype of combined heavy alcohol consumption and obesity has the potential to pose as a considerable health burden in the U.S. No studies using nationally representative data in the U.S. have reported their secular joint prevalence trends. We estimated the prevalence and examined the joint trends of heavy alcohol use and obesity over time among adult U.S. men and women in different age groups and according to race/ethnicity.

Methods

Using data from 10 cycles of the U.S. National Health and Nutrition Examination Survey (NHANES) from 1999 to 2020, we examined secular trends in the combined phenotype of heavy drinking and obesity overall and by age-group, sex, and race/ethnicity. The main outcome measures were prevalence of heavy alcohol consumption (>14 drinks/week in men and >7 drinks/week in women) and obesity (BMI ≥30).

Findings

In 45,292 adults (22,684 men, mean age 49.26 years; and 22,608 women, mean age 49.86), the overall weighted prevalence of combined heavy alcohol drinking and obesity increased from 1.8% (95% CI: 1.2%, 3.1%) in 1999-2000 to 3.1% (95% CI: 2.7%, 3.7%) in 2017-2020 representing an increase of 72% over time. In the joinpoint regression, the combined phenotype of heavy alcohol consumption and obesity increased by 3.25% (95% CI: 1.67%, 4.85%) per year overall from 1999 to 2017. An increasing trend of 9.94% (95% CI: 2.37%, 18.06%) per year was observed among adults aged between 40 and 59 years from 2007 onwards. Prevalence of heavy alcohol consumption in obesity increased at a faster rate among women (APC, 3.96%; 95% CI: 2.14%, 5.82%) than men (APC, 2.47%; 95% CI: 0.63%, 4.35%), and increased among non-Hispanic Whites (APC, 4.12%; 95% CI: 1.50%, 6.82%) and non-Hispanic Blacks (APC, 2.78%; 95% CI: 0.47%, 5.14%), but not Hispanics.

Interpretation

The prevalence of combined heavy alcohol consumption and obesity increased overall in the U.S., but the rate of increase differed by age, sex, and race/ethnic groups. Given their independent and potential synergistic effects on premature mortality, public health policies on alcohol consumption need to reflect the background obesity epidemic.

The most common pulmonary diseases length of stay, and characteristics of patients admitted to pulmonary service

BACKGROUND

Although chronic respiratory diseases are prevalent in Saudi Arabia, there are limited data on the patient burden and associated factors. The aim of this study is to identify the chronic respiratory diseases frequently admitted to pulmonary services and to determine the patient's characteristics, associated comorbidities readmission rate, and reason for a more extended stay in hospital.

METHODS

A prospective study was conducted over a 5-year period at King Abdulaziz Medical City-Riyadh, Saudi Arabia, in the Pulmonary Division, between March 2015 and December 2019. Data on demographics, comorbidities, and chronic respiratory diseases were collected.

RESULTS

Total patients admitted were 1315 patients, female 54.2%, the mean age was 62.4 (SD±17.6), and the ages ranged from 14 to 98 years. Overall, chronic obstructive pulmonary disease was the most common respiratory disease requiring admission (17.9%), followed by interstitial lung disease (15.8%), bronchiectasis (11.9%), and obesity hypoventilation syndrome (10.8%). The most common comorbidities were obesity (42.5%), diabetes 49.1%, and hypertension 54.9%. Only 135 (10.3%) were readmitted within 30 days posthospital discharge. Among the patients who were readmitted, 103 (76.3%) were readmitted due to issues related to previous admission diagnosis, noncompliance 75 (55.5%), social reasons, and premature discharges in 51 (37.8%) and 29 (21.5%) of the cases, respectively. The respiratory disease varied significantly by gender, age, obesity status, comorbidities, length of stay (LOS), and admissions.

CONCLUSION

Chronic respiratory diseases are prevalent in our population and are mainly influenced by gender, age, obesity status, comorbidities, LOS, and admissions. Policymakers and health professionals need to recognize the burden of chronic respiratory diseases on patients and health systems and implement effective prevention programs.

The prevalence and burden of avoidant/restrictive food intake disorder (ARFID) in a general adolescent population

BACKGROUND

Little is known about the prevalence and impairment associated with possible Avoidant/restrictive food intake disorder (ARFID) in community adolescent populations. We aimed to investigate the prevalence, health-related quality of life (HRQoL), and psychological distress associated with possible ARFID in a sample of adolescents from the general population in New South Wales, Australia.

METHODS

A representative sample of 5072 secondary school students aged between 11 and 19 years completed the online EveryBODY survey in 2017. The survey included demographic data, eating behaviours, psychological distress and both physical and psychosocial health-related quality of life.

RESULTS

The prevalence of possible ARFID was 1.98% (95% CI 1.63-2.41) and did not differ significantly across school years 7-12. The weight status of participants with possible ARFID did not differ significantly from those without possible ARFID. When measuring gender identity, the ratio of males to females with possible ARFID was 1:1.7. This was statistically significant, however, the effect size was very small. Psychological distress and HRQoL did not differ significantly between the possible ARFID and non-ARFID group.

CONCLUSIONS

The prevalence of possible ARFID was found to be similar to that of anorexia nervosa and binge eating disorder in the general adolescent population. Adolescents who identify as girls rather than boys may be more likely to develop ARFID, replication with new samples is required to confirm these findings. The impact of ARFID on HRQoL may be minimal in adolescence and become more significant in adulthood, further research using longitudinal design, healthy control groups and/or diagnostic interviews is required.

Incidence and mortality trends of neglected tropical diseases and malaria in China and ASEAN countries from 1990 to 2019 and its association with the socio-demographic index

BACKGROUND

People in China and the countries in the Association of Southeast Asian Nations (ASEAN) are affected by neglected tropical diseases and malaria (NTDM). In this study, we aimed to assess the current status and trends of NTDM burden from 1990 to 2019 in China and ASEAN countries, and also explore the association of NTDM burden with socio-demographic index (SDI).

METHODS

The data from the Global Burden of Diseases Study 2019 (GBD 2019) results were used. Absolute incidence and death number, and age-standardized incidence and mortality rate (ASIR and ASMR) of NTDM in China and ASEAN were extracted. The estimated annual percentage change (EAPC) and join-point regression in the rates quantified the trends. Nonlinear regression (second order polynomial) was used to explore the association between SDI and ASRs.

RESULTS

The ASIR of NTDM increased in China, Philippines, Singapore and Brunei, at a speed of an average 4.15% (95% CI 3.83-4.47%), 2.15% (1.68-2.63%), 1.03% (0.63-1.43%), and 0.88% (0.60-1.17%) per year. Uptrends of ASIR of NTDM in recent years were found in China (2014-2017, APC = 10.4%), Laos (2005-2013, APC = 3.9%), Malaysia (2010-2015, APC = 4.3%), Philippines (2015-2019, APC = 4.2%), Thailand (2015-2019, APC = 2.4%), and Vietnam (2014-2017, APC = 3.2%, all P < 0.05). Children < 5 had relatively low incidences but unexpectedly high mortality rates of NTDM in most ASEAN countries. Both incidence and mortality rates of NTDM were higher in older people. ASIR and ASMR of NTDM had a U-shaped association with SDI.

CONCLUSIONS

The burden of NTDM in China and ASEAN countries was still huge and affects vulnerable and impoverished populations' livelihoods, including children under the age of 5 and people aged 60 and older. Facing with the large burden and complex situation of NTDM in China and ASEAN countries, regional cooperating strategies are needed to reduce the burden of NTDM, so as to achieve the goal of elimination in the world.

Global, regional, and national burden of asthma and its attributable risk factors from 1990 to 2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

The burden of asthma in terms of premature death or reduced quality of life remains a huge issue. It is of great importance to evaluate asthma burden geographically and time trends from 1990 to 2019 and to assess the contributions of age, period, and cohort effects at global level.

METHODS

Asthma prevalence, deaths, and disability adjusted life years (DALYs) as well as risk-attributable burden were collected from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 database and were compared by age and sex. The Smoothing Splines models were used to estimate the relationship between asthma DALYs and the sociodemographic index (SDI). The Age-Period-Cohort model was used to determine effects of ages, periods, and birth cohorts on disease rates.

RESULTS

Between 1990 and 2019, the declines were 24.05% (95% uncertainty interval [UI] - 27.24 to - 20.82) in age-standardized asthma prevalence, 51.3% (- 59.08 to - 43.71) in mortality, and 42.55% (- 48.48 to - 36.61) in DALYs rate. However, the burden of asthma continued to rise, with an estimated 262.41 million prevalent cases globally (95% UI 224.05 to 309.45). Asthma caused greater DALYs in females than in males among people aged 20 years and older. The lowest age-standardized DALYs rate was observed at a SDI of approximately 0.70. The Longitudinal age curves showed an approximate W-shaped pattern for asthma prevalence and a likely J-shaped pattern for asthma mortality. The period effect on prevalence and mortality of asthma decreased from 1990 to 2019. Compared with the 1955-1959 birth cohort, the prevalence relative risk (RR) of asthma was highest in the 1905-1909 birth cohort, whereas the mortality RR continued to decline. At the global level, the percentages of high body-mass index, occupational asthmagens, and smoking contributing to DALYs due to asthma were 16.94%, 8.82%, and 9.87%, respectively.

CONCLUSIONS

Although the age-standardized rates of asthma burden declined in the past 30 years, the overall burden of asthma remains severe. High body mass index becomes the most important risk factor for DALYs due to asthma at the global level.

Clinical and economic hospital burden of acute respiratory infection (BARI) due to respiratory syncytial virus in Spanish children, 2015-2018

Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infection (ALRI) in children, causing frequent outpatient visits and hospitalizations. Our study aimed to describe the clinical and direct economic burden of ALRI hospitalizations related to RSV in children in Spain and the characteristics of patients and their episodes. In this retrospective study, ALRI hospitalizations in children aged < 5 years for 2015-2018 were reviewed using anonymized administrative public hospital discharge data from Spain. Three case definitions were considered: (a) RSV-specific; (b) RSV-specific and unspecified acute bronchiolitis (RSV-specific and bronchiolitis); and (c) RSV-specific and unspecified ALRI (RSV-specific and ALRI). The study reported a mean of 36,743 yearly admissions potentially due to RSV, resulting in a mean annual cost of €87.1 million. RSV-specific codes accounted for 39.2% of cases, unspecified acute bronchiolitis for 20.1%, and other unspecified ALRI codes for the remaining 40.6%. The mean hospitalization rate per 1,000 children was 55.5 in the first year of life, 16.0 in the second, and 5.4 between 24 and 59 months. A considerable proportion of cases occurred in children under two years old (> 80.4%) and even during the first year of life (> 61.7%). Otherwise healthy children accounted for 92.9% of hospitalizations and 83.3% of costs during the period. Children born preterm accounted for 1.3% of hospitalizations and 5.7% of costs. The findings revealed that RSV still contributes to a high burden on the Spanish health care system. Children under one year of age and otherwise healthy term infants accounted for most of the substantial clinical and economic burden of RSV. Current evidence potentially underestimates the true epidemiology and burden of severe RSV infection; thus, further studies focusing on the outpatient setting are needed.

Economic impact of a more extensive use of FENO testing on the Italian population with asthma

BACKGROUND

Asthma is a common chronic inflammatory airway affecting over 260 million people worldwide, and characterized, in the large majority of cases, by the so-called "type 2 inflammation". Fractional exhaled nitric oxide (FE_NO) testing is noninvasive point-of-care tool to assess type 2 inflammation and therefore improve asthma management. It has been suggested to determine eligibility for a specific biologic therapy and predict likelihood to respond. The aim of this study was to estimate the overall economic impact of an extensive use of FE_NO testing on the Italian population with asthma, including extra costs of testing and savings generated by more appropriate prescriptions, increased adherence and lower frequency of exacerbations.

METHODS

A cost of illness analysis was firstly performed to estimate the yearly economic burden from the National Healthcare Service (NHS) perspective in Italy of the management of asthmatic patients with standard of care (SOC) according to the application of GINA (Global Initiative for Asthma) guidelines; then, we evaluated the changes in the economic burden in patient management by introducing FE_NO testing into clinical practice. The cost items considered were: visits/exams, exacerbations, drugs, management of adverse events caused by short-term oral corticosteroids use. Efficacy of FeNO test and SOC is based on literature evidence. Costs refer to published data or Diagnosis Related Group/outpatient tariffs.

RESULTS

Considering one asthma visit every 6 months, the total yearly cost for the management of patients with asthma in Italy is 1,599,217,876€ (409.07€ per patient), while for FE_NO testing strategy this figure is 1,395,029,747€ (356.84€ per patient). An increased utilization rate of FE_NO testing from 50 to 100% of patients may lead to savings for the NHS from about 102 to 204 million € compared to SOC.

CONCLUSIONS

Our study showed that FeNO testing strategy may improve the management of asthmatic patients leading to significant savings for the NHS.

Impact of pharmaceutical care integrated at a psychosocial intervention to reduce caregiver's burden in Alzheimer's disease or related dementias: Negative results at 18 months and difficulties to conduct PHARMAID RCT

Background

Psychosocial interventions for caregivers of patients with Alzheimer disease and relative dementias (ADRD) reported a caregiver burden improvement. Multicomponent intervention integrating pharmaceutical care has not yet been evaluated while ADRD patients and their caregivers are exposed to high risk of drug-related problems. The PHARMAID study aimed to assess the impact of personalized pharmaceutical care integrated to a psychosocial program on the burden of ADRD caregivers at 18 months.

Methods

The PHARMAID RCT was conducted between September 2016 and June 2020 [ClinicalTrials.gov: NCT02802371]. PHARMAID study planned to enroll 240 dyads, i.e. ADRD patients and caregivers, whose inclusion criteria were: outpatient with mild or major neurocognitive disorders due to ADRD, living at home, receiving support from a family caregiver. Three parallel groups compared a control group with two interventional groups: psychosocial intervention and integrated pharmaceutical care at a psychosocial intervention. The main outcome was the caregiver burden assessed by the Zarit Burden Index (ZBI, score range 0-88) at 18 months.

Results

Overall, 77 dyads were included (32% of the expected sample size). At 18 months, the mean ZBI scores were 36.7 ± 16.8 in the control group, 30.3 ± 16.3 for the group with psychosocial intervention, and 28.8 ± 14.1 in group with integrated pharmaceutical care at psychosocial intervention. No significant difference was demonstrated between the three groups (p = 0.326).

Conclusions

The findings suggest that PHARMAID program had no significant impact on caregiver burden at 18 months. Several limitations have been highlighted and discussed by the authors in order to formulate recommendations for further research.

The Burden of the "Simple Ankle Sprains": A Review of the Epidemiology and Long-Term Impact

Lateral ankle sprain (LAS) is not as simple as it was believed to be as it has substantial negative impacts on the active sporting population. The negative impact on physical function, quality of life (QoL) and economic burden is significant with increased risk of reinjury, development of chronic lateral ankle instability and posttraumatic ankle osteoarthritis resulting in functional deficits, decreased QoL and chronic disabilities. Economic burden from a societal perspective demonstrated notably higher indirect costs from productivity loss. Preventative interventions with early surgery for a selective cohort of active sporting population may be considered to mitigate morbidities associated with LAS.

Availability, accessibility and use of antivenom for snakebite envenomation in Africa with proposed strategies to overcome the limitations

Africa remains one of the regions with the highest incident and burden of snakebite. The goal of the World Health Organization to halve the global burden of snakebite by 2030 can only be achieved if sub-optimal access to antivenoms in the most affected regions is addressed. We identified upstream, midstream, and downstream factors along the antivenom value chain that prevent access to antivenoms in the African region. We identified windows of opportunities that could be utilized to ensure availability, accessibility, and affordability for snakebite endemic populations in Africa. These include implementation of multicomponent strategies such as intensified advocacy, community engagement, healthcare worker trainings, and leveraging the institutional and governance structure provided by African governments to address the challenges identified.

The burden of osteoarthritis: Is it a rising problem?

The objective of this review is to provide an overview of the current status of osteoarthritis (OA) as one of the most common joint disorders worldwide. Despite being the 11th cause of disability globally, there has been an increase in the prevalence, annual incidence, and years lived with disability of OA, particularly in developed and developing countries. Erosive hand OA, which affects approximately 10% of the general population, has been associated with a higher clinical burden compared to non-erosive hand OA. Patients with knee and hip OA, but not hand OA, are also at an increased risk of cardiovascular disease and all-cause mortality. Furthermore, OA has a significant contribution to healthcare costs in most countries. The recent COVID-19 pandemic has further exacerbated the disease burden of OA patients due to limited access to medical and surgical treatment. With increasing life expectancy and the aging of the global population, the burden of OA is expected to worsen. Therefore, this review highlights the importance of improving population and policymaker awareness of risk factors, such as obesity and injury, as well as early intervention and management of OA to control the future burden of the disease.

Global Impact of Obesity

The prevalence of preobesity and obesity is rising globally, multiple epidemiologic studies have identified preobesity and obesity as predisposing factors to a number of noncommunicable diseases including type 2 diabetes (T2DM), cardiovascular disease (CVD), and cancer. In this review, we discuss the epidemiology of obesity in both children and adults in different regions of the world. We also explore the impact of obesity as a disease not only on physical and mental health but also its economic impact.

Early atrial fibrillation detection is associated with higher arrhythmic burden in patients with loop recorder after an embolic stroke of undetermined source

Background

After an embolic stroke of undetermined source (ESUS), long-term monitoring is recommended to start an anticoagulation therapy in patients with documented atrial fibrillation (AF). Literature is sparse about the AF burden following an ESUS, although this might have significant implications in terms of clinical management and therapeutic strategy. Our primary aim was to evaluate a possible association between early detection of AF (within 90 days from the ILR implantation) and higher AF burden.

Methods

This is a retrospective single-center study of 129 consecutive patients who received implantable loop recorders (ILRs) after an ESUS for detection of subclinical AF and their AF burden.

Results

Mean age was 70.3 ± 10.4 years old (males: 51.9%). Atrial fibrillation was found in 40.3% of patients. Patients with AF were older, presented a higher CHAD₂S₂-Vasc Score and greater left atrial volume compared with patients without AF. The median AF burden was 1.2%; 59% of patients had the first AF episode within 90 days from the ILR implant while 41% experienced the first episode later than 90 days. The AF burden was significantly higher in the former group. Of note, the univariate analysis showed that only early AF detection was significantly associated with AF burden >1% (OR 20.0; 95% CI 1.68-238.6, p = 0.01).

Conclusions

The early AF detection was found to be significantly associated with a higher burden of AF.

Global prevalence of drug-resistant tuberculosis: a systematic review and meta-analysis

BACKGROUND

Tuberculosis is a bacterial infectious disease, which affects different parts of a human body, mainly lungs and can lead to the patient's death. The aim of this study is to investigate the global prevalence of drug-resistant tuberculosis using a systematic review and meta-analysis.

METHODS

In this study, the PubMed, Scopus, Web of Science, Embase, ScienceDirect and Google Scholar repositories were systematically searched to find studies reporting the global prevalence of drug-resistant tuberculosis. The search did not entail a lower time limit, and articles published up until August 2022 were considered. Random effects model was used to perform the analysis. The heterogeneity of the studies was examined with the I² test. Data analysis was conducted within the Comprehensive Meta-Analysis software.

RESULTS

In the review of 148 studies with a sample size of 318,430 people, the I² index showed high heterogeneity (I² = 99.6), and accordingly random effects method was used to analyze the results. Publication bias was also examined using the Begg and Mazumdar correlation test which indicated the existence of publication bias in the studies (P = 0.008). According to our meta-analysis, the global pooled prevalence of multi-drug resistant TB is 11.6% (95% CI: 9.1-14.5%).

CONCLUSIONS

The global prevalence of drug-resistant tuberculosis was found to be very high, thus health authorities should consider ways to control and manage the disease to prevent a wider spread of tuberculosis and potentially subsequent deaths.

Appraisal of the costs, health effects, and cost-effectiveness of screening, prevention, treatment and policy-indicated evidence-based interventions for eating disorders: a systematic review protocol

BACKGROUND

Having reliable information to make decisions about the allocation of healthcare resources is needed to improve well-being and quality-of-life of individuals with eating disorders (EDs). EDs are a main concern for healthcare administrators globally, particularly due to the severity of health effects, urgent and complex healthcare needs, and relatively high and long-term healthcare costs. A rigorous assessment of up-to-date health economic evidence on interventions for EDs is essential for informing decision-making in this area. To date, health economic reviews on this topic lack a comprehensive assessment of the underlying clinical utility, type and amount of resources used, and methodological quality of included economic evaluations. The current review aims to (1) detail the type of costs (direct and indirect), costing approaches, health effects, and cost-effectiveness of interventions for EDs; (2) assess the nature and quality of available evidence to provide meaningful insights into the health economics associated with EDs.

METHODS

All interventions for screening, prevention, treatment, and policy-based approaches for all Diagnostic and Statistics Manual (DSM-IV and DSM-5) listed EDs among children, adolescents, and adults will be included. A range of study designs will be considered, including randomised controlled trials, panel studies, cohort studies, and quasi-experimental trials. Economic evaluations will consider key outcomes, including type of resources used (time and valued in a currency), costs (direct and indirect), costing approach, health effects (clinical and quality-of-life), cost-effectiveness, economic summaries used, and reporting and quality assessments. Fifteen general academic and field-specific (psychology and economics) databases will be searched using subject headings and keywords that consolidate costs, health effects, cost-effectiveness and EDs. Quality of included clinical studies will be assessed using risk-of-bias tools. Reporting and quality of the economic studies will be assessed using the widely accepted Consolidated Health Economic Evaluation Reporting Standards and Quality of Health Economic Studies frameworks, with findings of the review presented in tables and narratively.

DISCUSSION

Results emanating from this systematic review are expected to highlight gaps in healthcare interventions/policy-focused approaches, under-estimates of the economic costs and disease-burden, potential under-utilisation of ED-related resources, and a pressing need for more complete health economic evaluations.

Burden of migraine in patients attending Belgian headache specialists: real-world evidence from the BECOME study

INTRODUCTION

Migraine is a primary headache disorder, which imposes a major burden on the sufferers. The BECOME study (Burden of migrainE in specialist headache Centers treating patients with prOphylactic treatMent failurE) attempted to characterize and assess the prevalence, burden and healthcare resource utilization of migraine patients presenting in specialized headache centers in Europe and Israel. In this paper, we will describe the patient characteristics of the Belgian headache centers.

METHODS

The BECOME study was a prospective, non-interventional, cross-sectional study consisting of two parts. In the first part of the study, data were collected from subjects with a diagnosis of migraine. Subsequently, patients with ≥ 4 monthly migraine days (MMD) and ≥ 1 prior preventive treatment failure (PPTF) filled out validated questionnaires to assess the burden of disease.

RESULTS

In part 1 of the Belgian study population (N = 806), 45% of patients reported ≥ 8 MMD and 25% had failed ≥ 4 preventive treatments. In part 2 (N = 90), more than 90% of patients reported having severe impact of headache on daily life and having severe migraine-related disability. The impact was the highest for patients with ≥ 15 MMD, however, even within the patient population with < 8 MMD, the burden was significant. Almost 40% of the study population suffered from anxiety.

CONCLUSIONS

These findings in the Belgian sample of the BECOME study demonstrate the substantial burden and unmet need for the management of difficult-to-treat migraine.

Unemployment and early retirement among patients with epilepsy - A study on predictors, resilience factors and occupational reintegration measures

The primary aim of this study was to identify predictors and resilience factors for unemployment and early retirement in patients with epilepsy of working age based on data from a multicenter German cohort study performed in 2020 (n = 456) by using multivariate binary logistic regression analysis. A second aim was to assess the assumed working ability of patients as well as the use of occupational reintegration measures. The unemployment rate was 8.3%, and 18% of patients had retired early due to epilepsy. Multivariate binary logistic regression analysis identified the presence of a relevant disability and frequent seizures as significant predictors of unemployment and early retirement, while seizures in remission were the only resilience factor associated with job retention. Regarding occupational incapacity, at the time of the survey, most of the patients in early retirement or unemployment were fit for work in their original or extended occupational setting. The proportion of patients with recent epilepsy-related occupational retraining (0.4%) or job changes (0.9%) was low, and only 2.4% reported an epilepsy-related reduction in work time. These findings underline the persistent disadvantage of patients with epilepsy in the professional field and the urgent need for effective, comprehensive work reintegration measures that must be made accessible for all patients.

New respiratory syncytial virus immunization products in low- and middle-income countries: potential for cost-effective impact on a high burden of disease in young infants

As new, efficacious respiratory syncytial virus (RSV) immunization products reach the market, affordable pricing as well as improved estimation of disease burden and the full potential and cost effectiveness of RSV prevention in the hardest hit geographies in low- and middle-income countries are critical to inform country adoption and enable maximum impact against infant disease and mortality globally. The data reported in the special issue underscore the enormous burden, and associated cost, of RSV disease in young infants in several LMICs, including Kenya and South Africa, as well as the potential for RSV maternal vaccines or long-acting monoclonal antibodies, to be cost-effective and possibly even cost-saving.

Addressing influenza's underestimated burden - Iberian experts call to action

This paper reviews findings from the Burden of Acute Respiratory Infections study on the burden of influenza in Iberia, and its potential underestimation, and proposes specific measures to lessen influenza's impact.

Concept Elicitation Interviews and Conceptual Model to Understand the Patient Experience of Limb Girdle Muscular Dystrophy

INTRODUCTION

Limb girdle muscular dystrophies (LGMDs) are a group of rare and heterogeneous disorders involving progressive wasting of shoulder and pelvic girdle musculature. This study aimed to generate qualitative evidence on patient and caregiver experiences with symptoms and impacts of LGMD on overall function and daily life for sarcoglycanopathy subtypes 2C/R5, 2D/R3, and 2E/R4.

METHODS

Twenty-three individuals with LGMD with (n = 5) or without (n = 18) a caregiver participated in 60-minute semi-structured video interviews. Interview transcripts were analyzed using thematic analysis. Differences in patient experience by ambulation status and LGMD subtype were examined.

RESULTS

Participants were ambulatory (n = 14) and non-ambulatory (n = 9), representing three subtypes: 2C/R5 (n = 4), 2D/R3 (n = 12), and 2E/R4 (n = 7), with mean age of 34.8 years (SD = 16.08). 56.5% identified as female. Conceptual saturation was achieved within 18/23 interviews. Ambulatory participants identified difficulty with complex physical activities, e.g., running (n = 11, 78.6%), physical strength (n = 14, 100%), and difficulty with transfers, e.g., difficulty getting off the floor (n = 10, 71.4%). All non-ambulatory participants discussed problems with activities of daily living (ADLs) and transfers, e.g., getting in/out of bed and upper extremity function, particularly reaching (n = 8, 88.9%) and fine motor skills (n = 6, 66.7%). Fatigue and pain were reported by the majority of participants (n = 16, 69.6% and n = 19, 82.6%, respectively). A conceptual disease model was developed illustrating symptoms and impacts and their relationships to disease stage, capturing the patient experience across LGMD disease trajectory.

CONCLUSIONS

This study contributes to the limited evidence describing the patient experience of living with LGMD. The conceptual model can inform patient-centered assessment in future LGMD clinical trials.

Epidemiological, Clinical, Patient-Reported and Economic Burden of Inflammatory Bowel Disease (Ulcerative colitis and Crohn's disease) in Spain: A Systematic Review

INTRODUCTION

This study describes the epidemiological, clinical, patient-reported and economic burden of inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), in Spain.

METHODS

A systematic review was performed of observational studies reporting the epidemiological, clinical, patient-reported and economic burden of IBD in the Spanish population, from 2011 to 2021. Original articles and conference abstracts published in English or Spanish were eligible.

RESULTS

A total of 45 publications were included in the review. The incidence of IBD in adults ranged from 9.6 to 44.3 per 100,000 inhabitants (4.6 to 18.5 for CD and 3.4 to 26.5 for UC). The incidence increased between 1.5- and twofold from 2000 to 2016 (regionally). Up to 6.0% (CD) and 3.0% (UC) IBD-associated mortality was reported. Disease onset predominantly occurs between 30 and 40 years (more delayed for UC than CD). Most frequently reported gastrointestinal manifestations are rectal bleeding in UC and weight loss in CD. Extraintestinal manifestations (EIM) have been described in up to 47.4% of patients with CD and 48.1% of patients with UC. Psychiatric comorbidities were frequently reported in both CD and UC (depression up to 20% and anxiety up to 11%). Reduced health-related quality of life (HRQoL) compared to the general population was reported. Significant symptomatology was associated with high levels of anxiety, depression, stress and lower HRQoL. Main healthcare resources reported were emergency department visits (24.0%), hospitalization (14.7%), surgery (up to 11%) and use of biologics (up to 60%), especially in CD. Direct and indirect annual costs per patient with UC were €1754.1 and €399.3, respectively.

CONCLUSION

Patients with CD and UC present a high disease burden which negatively impacts their HRQoL, leading to elevated use of resources.

National and subnational burden of female and male breast cancer and risk factors in Iran from 1990 to 2019: results from the Global Burden of Disease study 2019

BACKGROUND

Breast cancer (BC) is one of the most burdensome cancers worldwide. Despite advancements in diagnostic and treatment modalities, developing countries are still dealing with increasing burdens and existing disparities. This study provides estimates of BC burden and associated risk factors in Iran at the national and subnational levels over 30 years (1990-2019).

METHODS

Data on BC burden for Iran were retrieved from the Global Burden of Disease (GBD) study from 1990 to 2019. GBD estimation methods were applied to explore BC incidence, prevalence, deaths, disability-adjusted life years (DALYs), and attributable burden to risk factors based on the GBD risk factors hierarchy. Moreover, decomposition analysis was performed to find the contribution of population growth, aging, and cause-specific incidence in the total incidence change. Age-standardized rates (per 100,000 population) and 95% uncertainty intervals (UI) were reported based on sex, age, and socio-demographic index (SDI).

RESULTS

Age-standardized incidence rate (ASIR) increased from 18.8 (95% UI 15.3-24.1)/100,000 in 2019 to 34.0 (30.7-37.9)/100,000 in 2019 among females and from 0.2/100,000 (0.2-0.3) to 0.3/100,000 (0.3-0.4) among males. Age-standardized deaths rate (ASDR) increased slightly among females from 10.3 (8.2-13.6)/100,000 in 1990 to 11.9 (10.8-13.1)/100,000 in 2019 and remained almost the same among males-0.2/100,000 (0.1-0.2). Age-standardized DALYs rate also increased from 320.2 (265.4-405.4) to 368.7 (336.7-404.3) among females but decreased slightly in males from 4.5 (3.5-5.8) to 4.0 (3.5-4.5). Of the 417.6% increase in total incident cases from 1990-2019, 240.7% was related to cause-specific incidence. In both genders, the BC burden increased by age, including age groups under 50 before routine screening programs, and by SDI levels; the high and high-middle SDI regions had the highest BC burden in Iran. Based on the GBD risk factors hierarchy, high fasting plasma glucose (FPG) and alcohol were estimated to have the most and the least attributed DALYs for BC among females, respectively.

CONCLUSIONS

BC burden increased from 1990 to 2019 in both genders, and considerable discrepancies were found among different provinces and SDI quintiles in Iran. These increasing trends appeared to be associated with social and economic developments and changes in demographic factors. Improvements in registry systems and diagnostic capacities were also probably responsible for these growing trends. Raising general awareness and improving screening programs, early detection measures, and equitable access to healthcare systems might be the initial steps to tackle the increasing trends.

Malaria Burden Stratification in Malawi- A report of a consultative workshop to inform the 2023-2030 Malawi Malaria Strategic Plan

Background: Malawi's National Malaria Control Programme (NMCP) is developing a new strategic plan for 2023-2030 to combat malaria and recognizes that a blanket approach to malaria interventions is no longer feasible. To inform this new strategy, the NMCP set up a task force comprising 18 members from various sectors, which convened a meeting to stratify the malaria burden in Malawi and recommend interventions for each stratum. Methods: The burden stratification workshop took place from November 29 to December 2, 2022, in Blantyre, Malawi, and collated essential data on malaria burden indicators, such as incidence, prevalence, and mortality. Workshop participants reviewed the malaria burden and intervention coverage data to describe the current status and identified the districts as a appropriate administrative level for stratification and action. Two scenarios were developed for the stratification, based on composites of three variables. Scenario 1 included incidence, prevalence, and under-five all-cause mortality, while Scenario 2 included total malaria cases, prevalence, and under-five all-cause mortality counts. The task force developed four burden strata (highest, high, moderate, and low) for each scenario, resulting in a final list of districts assigned to each stratum. Results: The task force concluded with 10 districts in the highest-burden stratum (Nkhotakota, Salima, Mchinji, Dowa, Ntchisi, Mwanza, Likoma, Lilongwe, Kasungu and Mangochi) 11 districts in the high burden stratum (Chitipa, Rumphi, Nkhata Bay, Dedza, Ntcheu, Neno, Thyolo, Nsanje, Zomba, Mzimba and Mulanje) and seven districts in the moderate burden stratum (Karonga, Chikwawa, Balaka, Machinga, Phalombe, Blantyre, and Chiradzulu). There were no districts in the low-burden stratum. Conclusion: The next steps for the NMCP are to review context-specific issues driving malaria transmission and recommend interventions for each stratum. Overall, this burden stratification workshop provides a critical foundation for developing a successful malaria strategic plan for Malawi.

[Informal caregivers in Germany: achieving work-life balance]

Informal caregivers are the main pillar of care provision in Germany. Almost a quarter of adults know a person who needs assistance or care. Caring for a person needing assistance is becoming an everyday task for more and more people. These demands must often be balanced with the requirements of work and/or care of underage children. Not only in this sandwich position informal caregivers neglect their own lives and endanger their health. The narrative review focuses on the challenges of reconciling care at home and work. In addition, the importance of informal caregiving as a relevant public health topic is discussed. A spotlight is placed on children in need of care and the particular demands of their caring parents. Current recommendations for a better reconciliation of care and work as well as for the recognition of relatives' valuable caregiving work provide an outlook on solution strategies that come from science and should be addressed by policymakers.

The economic burden of RSV-associated illness in children aged < 5 years, South Africa 2011-2016

BACKGROUND

Data on the economic burden of RSV-associated illness will inform decisions on the programmatic implementation of maternal vaccines and monoclonal antibodies. We estimated the cost of RSV-associated illness in fine age bands to allow more accurate cost-effectiveness models to account for a limited duration of protection conferred by short- or long-acting interventions.

METHODS

We conducted a costing study at sentinel sites across South Africa to estimate out-of-pocket and indirect costs for RSV-associated mild and severe illness. We collected facility-specific costs for staffing, equipment, services, diagnostic tests, and treatment. Using case-based data we calculated a patient day equivalent (PDE) for RSV-associated hospitalizations or clinic visits; the PDE was multiplied by the number of days of care to provide a case cost to the healthcare system. We estimated the costs in 3-month age intervals in children aged < 1 year and as a single group for children aged 1-4 years. We then applied our data to a modified version of the World Health Organization tool for estimating the mean annual national cost burden, including medically and non-medically attended RSV-associated illness.

RESULTS

The estimated mean annual cost of RSV-associated illness in children aged < 5 years was US dollars ($)137,204,393, of which 76% ($111,742,713) were healthcare system incurred, 6% ($8,881,612) were out-of-pocket expenses and 13% ($28,225,.801) were indirect costs. Thirty-three percent ($45,652,677/$137,204,393) of the total cost in children aged < 5 years was in the < 3-month age group, of which 52% ($71,654,002/$137,204,393) were healthcare system incurred. The costs of non-medically attended cases increased with age from $3,307,218 in the < 3-month age group to $8,603,377 in the 9-11-month age group.

CONCLUSIONS

Among children < 5 years of age with RSV in South Africa, the highest cost burden was in the youngest infants; therefore, interventions against RSV targeting this age group are important to reduce the health and cost burden of RSV-associated illness.

The burden of RSV-associated illness in children aged < 5 years, South Africa, 2011 to 2016

BACKGROUND

Vaccines and monoclonal antibodies to protect the very young infant against the respiratory syncytial virus (RSV)-associated illness are effective for limited time periods. We aimed to estimate age-specific burden to guide implementation strategies and cost-effectiveness analyses.

METHODS

We combined case-based surveillance and ecological data to generate a national estimate of the burden of RSV-associated acute respiratory illness (ARI) and severe acute respiratory illness (SARI) in South African children aged < 5 years (2011-2016), including adjustment for attributable fraction. We estimated the RSV burden by month of life in the < 1-year age group, by 3-month intervals until 2 years, and then 12 monthly intervals to < 5 years for medically and non-medically attended illness.

RESULTS

We estimated a mean annual total (medically and non-medically attended) of 264,112 (95% confidence interval (CI) 134,357-437,187) cases of RSV-associated ARI and 96,220 (95% CI 66,470-132,844) cases of RSV-associated SARI (4.7% and 1.7% of the population aged < 5 years, respectively). RSV-associated ARI incidence was highest in 2-month-old infants (18,361/100,000 population, 95% CI 9336-28,466). The highest incidence of RSV-associated SARI was in the < 1-month age group 14,674/100,000 (95% CI 11,175-19,645). RSV-associated deaths were highest in the first and second month of life (110.8 (95% CI 74.8-144.5) and 111.3 (86.0-135.8), respectively).

CONCLUSIONS

Due to the high burden of RSV-associated illness, specifically SARI cases in young infants, maternal vaccination and monoclonal antibody products delivered at birth could prevent significant RSV-associated disease burden.

Assessing the psychometric properties of persian version of Zarit Burden interview among family caregivers of patients with multiple sclerosis

BACKGROUND

Caring for patients with multiple sclerosis (MS) imposes a great burden on caregivers and affects their lives in various aspects. This study aimed to evaluate the psychometric properties of Persian version of 22-item Zarit Burden Interview (ZBI-22) among family caregivers of patients with MS.

METHODS

This methodological study was conducted in Fars province, southern of Iran. For this purpose, 120 family caregivers were recruited to participate in the study from January to March 2022. Zarit Burden Interview (ZBI) was translated into Persian through forward-backward method. Face and content validity were assessed. Construct validity was assessed using exploratory factor analyses (EFA), and its reliability was assessed by measuring internal consistency and testretest stability.

RESULTS

According to face validity, the impact scores of all items were more than 1.5. Content validity ratio and content validity index values of all 22 items were 0.64-1 and 0.82-1, respectively. The scalelevel CVI/Ave was 0.97. Based on the results of factor analysis, five factors with eigenvalues more than 1 were extracted, which altogether explained 62.62% of the total variance of ZBI score. Among 22 items, one item was deleted during EFA validity assessment. Factor loading values ranged from 0.40 to 0.88. The reliability of the scale was confirmed (total Cronbach's alpha of the ZBI = 0.88). Moreover, testretest stability assessment revealed no significant difference between test and retest scores (P > 0.05). The intraclass correlation (ICC) for the ZBI and ICCs among its factors were 0.88 and 0.6-0.86, respectively.

CONCLUSION

The Persian version of five-factor structure ZBI can be a valid and reliable scale, and it can be used to assess caregiver burden among family caregivers of patients with MS in Iran.

Assessment of the burden of outpatient clinic and MRI-guided needle muscle biopsies as reported by patients with facioscapulohumeral muscular dystrophy

Muscle biopsies are used in clinical trials to measure target engagement of the investigational product. With many upcoming therapies for patients with facioscapulohumeral dystrophy (FSHD), the frequency of biopsies in FSHD patients is expected to increase. Muscle biopsies were performed either in the outpatient clinic using a Bergström needle (BN-biopsy) or in a Magnetic Resonance Imaging machine (MRI-biopsy). This study assessed the FSHD patients' experience of biopsies using a customized questionnaire. The questionnaire was sent to all FSHD patients who had undergone a needle muscle biopsy for research purposes, inquiring about biopsy characteristics and burden, and willingness to undergo a subsequent biopsy. Forty-nine of 56 invited patients (88%) completed the questionnaire, reporting on 91 biopsies. The median pain score (scale 0-10) during the procedure was 5 [2-8], reducing to 3 [1-5] and 2 [1-3] after one and 24 h, respectively. Twelve biopsies (13.2%) resulted in complications, eleven resolved within 30 days. BN-biopsies were less painful compared to MRI-biopsies (median NRS: 4 [2-6] vs. 7 [3-9], p = 0.001). The burden of needle muscle biopsies in a research setting is considerate and should not be underestimated. MRI-biopsies have a higher burden compared to BN-biopsies.

The impact of cerebral small vessel disease burden and its imaging markers on gait, postural control, and cognition in Parkinson's disease

OBJECTIVE

This study aimed to investigate how cerebral small vessel disease (CSVD) burden and its imaging markers are related to alterations in different gait parameters in Parkinson's disease (PD) and whether they affect attention, information processing speed, and executive function when global mental status is relatively intact.

METHODS

Sixty-five PD patients were divided into the low CSVD burden group (n = 43) and the high CSVD burden group (n = 22). All patients underwent brain magnetic resonance imaging scans, clinical scale evaluations, and neuropsychological tests, as well as quantitative evaluation of gait and postural control. Multivariable linear regression models were conducted to investigate associations between CSVD burden and PD symptoms.

RESULTS

Between-group analysis showed that the high CSVD group had worse attention, executive dysfunction, information processing speed, gait, balance, and postural control than the low CSVD group. Regression analysis revealed that greater CSVD burden was associated with poor attention, impaired executive function, and slow gait speed; white matter hyperintensity was associated with slow gait speed, decreased cadence, increased stride time, and increased stance phase time; the presence of lacune was associated only with poor attention and impaired executive function; enlarged perivascular space in the basal ganglia was associated with gait speed.

CONCLUSIONS

CSVD burden may worsen gait, postural control, attention, and executive function in patients with PD, and different imaging markers play different roles. Early management of vascular risks and treatment of vascular diseases provide an alternate way to mitigate some motor and cognitive dysfunction in PD.

Estimates of the national burden of respiratory syncytial virus in Kenyan children aged under 5 years, 2010-2018

BACKGROUND

Respiratory syncytial virus (RSV) is among the leading childhood causes of viral pneumonia worldwide. Establishing RSV-associated morbidity and mortality is important in informing the development, delivery strategies, and evaluation of interventions.

METHODS

Using data collected during 2010-2018 from base regions (population-based surveillance studies in western Kenya and the Kilifi Health and Demographic Surveillance Study), we estimated age-specific rates of acute respiratory illness (ARI), severe acute respiratory illness (SARI-defined as hospitalization with cough or difficulty breathing with onset within the past 10 days), and SARI-associated deaths. We extrapolated the rates from the base regions to other regions of Kenya, while adjusting for risk factors of ARI and healthcare seeking behavior, and finally applied the proportions of RSV-positive cases identified from various sentinel and study facilities to the rates to obtain regional age-specific rates of RSV-associated outpatient and non-medically attended ARI and hospitalized SARI and severe ARI that was not hospitalized (non-hospitalized SARI). We applied age-specific RSV case fatality ratios to SARI to obtain estimates of RSV-associated in- and out-of-hospital deaths.

RESULTS

Among Kenyan children aged < 5 years, the estimated annual incidence of outpatient and non-medically attended RSV-associated ARI was 206 (95% credible interval, CI; 186-229) and 226 (95% CI; 204-252) per 1000 children, respectively. The estimated annual rates of hospitalized and non-hospitalized RSV-associated SARI were 349 (95% CI; 303-404) and 1077 (95% CI; 934-1247) per 100,000 children respectively. The estimated annual number of in- and out-of-hospital deaths associated with RSV infection in Kenya were 539 (95% CI; 420-779) and 1921 (95% CI; 1495-2774), respectively. Children aged < 6 months had the highest burden of RSV-associated severe disease: 2075 (95% CI; 1818-2394) and 44 (95% CI 25-71) cases per 100,000 children for hospitalized SARI and in-hospital deaths, respectively.

CONCLUSIONS

Our findings suggest a substantial disease burden due to RSV infection, particularly among younger children. Prioritizing development and use of maternal vaccines and affordable long-lasting monoclonal antibodies could help reduce this burden.

Disease burden of migraine and tension-type headache in non-high-income East and Southeast Asia from 1990 to 2019

BACKGROUND

The world faces severe challenges from migraine and tension-type headache (TTH), which cause grave disability to patients and place a heavy burden on their caregivers. However, headaches in specific individual regions have rarely been investigated. Therefore, we aimed to fully analyse and describe the current status and changing trends in migraine and TTH in non-high-income East and Southeast Asia to provide more detailed real-world information for policy-making.

METHODS

The migraine and TTH data used for analysis were all extracted from the Global Burden of Disease (GBD) database. We adopted three major indicators of disease burden, including prevalence, incidence, and years lived with disability (YLD), and two major metrics, including the absolute number and the age-standardized rate, in our present study for further evaluation by age and sex. The results are presented in the form of mean values and 95% uncertainty intervals (UIs). In addition, the differences between non-high-income East and Southeast Asia and other regions, as well as the potential associations between headache burden and socioeconomic background, were explored.

RESULTS

In 2019, approximately 195,702,169 migraine patients and 291,924,564 TTH patients lived in non-high-income East Asia, and 113,401,792 migraine patients and 179,938,449 TTH patients lived in non-high-income Southeast Asia. In terms of specific countries and regions, the highest age-standardized YLD rate (ASYR) of migraine was in Thailand [645 (95% UI: 64 to 1,554)]. The highest ASYR of TTH was in Indonesia [54 (95% UI: 15 to 197)]. Furthermore, people between the ages of 40 and 44, especially females, were identified as the main population that suffered from migraine and TTH. Unfortunately, we did not observe a significant association between headache burden and socioeconomic background.

CONCLUSIONS

To date, the threats from migraine and TTH in non-high-income East and Southeast Asia are still serious and ongoing, leading to prominently negative impacts on the daily life and work of local residents. Therefore, full attention and sound guidelines are urgently needed to obtain greater advantages in fighting against the burden of headache disorders in the future.

Financial Burden of Tuberculosis Patients - China, 2020

What is already known about this topic?

Tuberculosis (TB) is often referred to as "a disease of poverty," yet the information regarding the financial burden of TB care is limited and regionally representative.

What is added by this report?

This manuscript reported the national representative total and breakdown costs associated with TB care in China. The total cost per patient was 1,185 USD, of which 88% was direct cost and 37% was incurred prior to TB treatment.

What are the implications for public health practice?

TB patients experience a significant financial burden, and disparities exist among different regions and populations. Current TB care policies and packages are not sufficient to address this issue.

The HARDSHIP databases: a forthcoming free good from the Global Campaign against Headache

In order to pursue its purpose of reducing the global burden of headache, the Global Campaign against Headache has gathered data on headache-attributed burden from countries worldwide. These data, from the individual participants in adult population-based studies and child and adolescent schools-based studies, are being collated in two databases, which will be powerful resources for research and teaching and rich information sources for health policy.Here we briefly describe the structure and content of these databases, and announce the intention to make them available in due course as a free good.

Estimating the burden of influenza-attributable severe acute respiratory infections on the hospital system in Metropolitan France, 2012-2018

BACKGROUND

To date, estimating the burden of seasonal influenza on the hospital system in France has been restricted to influenza diagnoses in patients (estimated hospitalization rate of 35/100,000 on average from 2012 to 2018). However, many hospitalizations for diagnosed respiratory infections (e.g. pneumonia, acute bronchitis) occur without concurrent screening for virological influenza, especially in the elderly. Specifically, we aimed to estimate the burden of influenza on the French hospital system by examining the proportion of severe acute respiratory infections (SARI) attributable to influenza.

METHODS

Using French national hospital discharge data from 1/7/2012 to 30/6/2018, we extracted SARI hospitalizations with ICD-10 codes J09-J11 (influenza codes) in main or associated diagnoses, and J12-J20 (pneumonia and bronchitis codes) in main diagnoses. We estimated influenza-attributable SARI hospitalizations during influenza epidemics, as the number of influenza-coded hospitalizations plus the influenza-attributable number of pneumonia- and acute bronchitis-coded hospitalizations using periodic regression and generalized linear models. Additional analyses stratified by age group, diagnostic category (pneumonia and bronchitis), and region of hospitalization were performed using the periodic regression model only.

RESULTS

The average estimated hospitalization rate of influenza-attributable SARI during the five annual influenza epidemics covered (2013-2014 to 2017-2018) was 60/100,000 with the periodic regression model, and 64/100,000 with the generalized linear model. Over the six epidemics (2012-2013 to 2017-2018), of the 533,456 SARI hospitalizations identified, an estimated 227,154 were influenza-attributable (43%). Fifty-six percent of cases were diagnosed with influenza, 33% pneumonia, and 11% bronchitis. Diagnoses varied between age groups: 11% of patients under 15 years old had pneumonia versus 41% of patients aged 65 and older.

CONCLUSION

Compared to influenza surveillance in France to date, analyzing excess SARI hospitalizations provided a much larger estimate of the burden of influenza on the hospital system. This approach was more representative and allowed the burden to be assessed according to age group and region. The emergence of SARS-Cov-2 has led to a change in the dynamics of winter respiratory epidemics. The co-circulation of the three current major respiratory viruses (influenza, SARS-Cov-2, and RSV) and the evolution of diagnostic confirmation practices must now be taken into account when analyzing SARI.

Analysis of contemporary mortality trends in pulmonary embolism, United States, 1999-2020

BACKGROUND

A contemporary and comprehensive examination of mortality trends in pulmonary embolism (PE) is needed for the United States (US), as previous studies were either based on preceding data or limited to specific demographic subgroups. We aimed to assess the trends in PE deaths by age, sex, race/ethnicity, and census region in the US from 1999 through 2020.

METHODS

We analyzed national mortality data using the CDC WONDER database. PE deaths were identified using the ICD-10 Code- I-26. Age adjusted mortality rates (AAMR) were abstracted by age, sex, race/ethnicity, and census region. Temporal trends were assessed using five-year moving averages and Joinpoint regression models. Annual percentage changes (APC) in AAMR were estimated using Monte Carlo Permutation, and 95 % confidence intervals using the Parametric Method.

RESULTS

Overall mortality trends have stabilized since 2009 (APC = 0.6; 95 % CI: -0.3, 1.6), as were trends among Non-Hispanic Whites (APC = 0.6; 95 % CI: -0.2, 1.4), Non-Hispanic Blacks (APC = 0.7; 95 % CI: -0.2, 1.6), and Hispanics (APC = 1.4; 95 % CI: -0.7, 3.6). AAMR declined by 1.7 % per year (95 % CI: -2.8, -0.7) among Asians/Pacific Islanders and by 1.4 % per year (95 % CI: -2.8, -0.0) among American Indians/Alaska Natives, from 1999 to 2020. Contemporary trends have increased among males (APC = 1.0; 95 % CI: 0.2, 1.9), persons below 65 years of age (APC = 18.6; 95 % CI: 18.6, 18.6; APC = 2.3; 95 % CI: 1.4, 3.1), and persons from the Northeastern (APC = 1.0; 95 % CI: 0.1, 2.0) and Western regions (APC = 1.6; 95 % CI: 0.7, 2.6).

CONCLUSIONS

The decline in PE mortality recorded from 1999 through the mid-2000s has not been sustained in the last decade-overall trends have stabilized since 2009. However, there were differences by age, sex, race/ethnicity, and the US census region, with some subgroups demonstrating stationary, increasing, or declining trends. Further studies should examine the drivers of differential trends in the US population to inform evidence-based and culturally competent public health intervention efforts.

Self-perceived Burden for People With Life-threatening Illness: A Qualitative Systematic Review

CONTEXT

The perception of being a burden to others is a significant concern for people with life-threatening illness. It is unclear what underpins the concept of "self-perceived burden".

OBJECTIVES

To appraise and integrate primary evidence underpinning the concept of self-perceived burden (SPB) with respect to their informal caregivers among adult patients with life-threatening illness.

METHODS

This is a systematic review and a thematic synthesis of qualitative primary data. MEDLINE, Embase, PsycINFO, CINAHL, and Web of Science were searched in September 2021, supplemented by hand searching of textbooks and web search engines, peer-review journals, and contact with experts. Qualitative studies were included if they provided primary data of adult patients' (with life-limiting illness) SPB toward their informal caregivers. Studies were appraised using the Critical Appraisal Skills Programme checklist.

RESULTS

Nine studies were included, reporting on 219 patients who mostly had advanced life-threatening illness and needed physical assistance for daily activities. SPB is a highly subjective perception contrasting self and/or informal caregivers in the past, present, and future. Patients develop SPB feeling uncertain about caregivers' perceptions and increasing future burden. SPB interacts with other factors of surrounding complex balances (such as care needs, reality, and identity) which would change over time, and patients' reactions to SPB at the sacrifice of their wishes may conversely increase the total suffering.

CONCLUSION

SPB is not a static perception but a fluctuating and complex 'process' based on uncertainty. More diverse understandings and following interventions to achieve a better balance of care should be sought.

Impact of long-term outcomes on the caregivers of burn survivors

This prospective longitudinal study investigated the changes in caregiving burden, post-traumatic stress disorder (PTSD), and quality of life (QoL) of primary caregivers of burn survivors 48 h, 3 months, 6 months, and 12 months after the burn event. We also explored and identified relevant factors associated with these metrics. We collected data regarding the sociodemographic and injury characteristics of 69 caregivers and their survivors. Their responses were recorded to the Caregiver Burden Scale (CBS), Impact of Events Scale for Burn (IESB), and Short Form-36 questionnaires. Temporal changes in the CBS, IESB, and SF-36 scores and their differences were analyzed using the generalized estimating equation. Among the caregivers of children, QoL decreased with increasing children's total burn surface area (TBSA) and length of hospital stays, caregivers being female, decreasing caregivers' age, increasing the time required to travel to and from the hospital, and increasing global and subjective burdens. Among the caregivers of adults, QoL decreased with increasing survivors' TBSA and caregivers' PTSD. Based on these results, several recommendations for implementation in clinical practice include integrating caregivers into care plans and encouraging active participation, providing learning and consultation channels, and encouraging caregivers to schedule breaks from caregiving activities.

The burden of non-communicable diseases: A scoping review focus on the context of India

The mortality rate of non-communicable diseases (NCDs) contributes more in low-income and middle-income countries, also among individuals with lower socioeconomic status in high-income countries, making NCDs a big hurdle to minimizing global and national health disparities. Among 55 million fatalities worldwide in 2019, NCDs accounted for about 41 million (71%) deaths. The purpose of this scoping review was to comprehend the available literature on the burden of NCDs in India. This review included the studies that have been published between the period of 2009-2020. For this review, 18 full-text articles have been selected. A preliminary search was done to obtain articles from the search engines such as PubMed, Google Scholar, web of science, and Scopus. Our scoping review was focused on five major NCDs which are cardiovascular, hypertension, diabetes, cancer, and stroke. In 2019, around 17.9 million individuals died from cardiovascular disease (CVD), which is accounting for 32% of all deaths. As compared to Chandigarh and Jharkhand (0.12 million and 0.96 million, respectively) Tamil Nadu and Maharashtra (4.8 million and 9.2 million, respectively) have a higher percentage of the population affected by diabetes. In India, stroke is the fifth-significant cause of disability and the fourth-leading cause of fatality, which is accounting for 3.5 percent of all disabilities. India should construct a higher-level coordinating framework and devise an overarching policy or strategy tailored to NCDs. To limit risk factor exposure, it is necessary to emphasize health promotion and preventive actions.

Spanish adaptation of the Burden Assessment Scale in family caregivers of people diagnosed with borderline personality disorder

BACKGROUND

Caregiving is a strong source of stress and leads the family caregiver to experience the burden of being responsible for the care of a severely mentally ill family member. The Burden Assessment Scale (BAS) assesses burden in family caregivers. This study aimed to analyze the psychometric properties of the BAS in a sample of family caregivers of people diagnosed with Borderline Personality Disorder (BPD).

METHODS

Participants were 233 Spanish family caregivers (157 women and 76 men aged between 16-76 years old, M = 54.44, SD = 10.09) of people diagnosed with BPD. The BAS, the Multicultural Quality of Life Index, and the Depression Anxiety Stress Scale-21 were used.

RESULTS

An exploratory analysis resulted in a three-factor 16-item model (Disrupted Activities; Personal and Social Dysfunction; Worry, Guilt, and Being Overwhelmed) with an excellent fit (χ²(101) = 56.873, p = 1.000, CFI = 1.000, TLI = 1.000, RMSEA = .000, SRMR = .060), good internal consistency (ω = .93), a negative correlation with quality of life, and a positive correlation with anxiety, depression, and stress.

CONCLUSION

The model obtained for the BAS is a valid, reliable, and useful tool for assessing burden in family caregivers of relatives diagnosed with BPD.

Caregivers in anorexia nervosa: is grief underlying parental burden?

ABSTARCT

PURPOSE: Anorexia Nervosa (AN) is a severe chronic disorder and parents' experience of caregiving is usually marked by emotional distress and burden. Severe chronic psychiatric disorders are known to be linked with the concept of grief. Grief has not been investigated in AN. The aim of this study was to explore parents' and adolescents' characteristics that may be related to parental burden and grief in AN, and the link between these two dimensions.

METHODS

Eighty mothers, 55 fathers and their adolescents (N  =  84) hospitalized for AN participated in this study. Evaluations of clinical characteristics of the adolescent's illness were completed, as well as self-evaluations of adolescent and parental emotional distress (anxiety, depression, alexithymia). Levels of parental burden were evaluated with the Experience of Caregiving Inventory and levels of parental grief with the Mental Illness Version of the Texas Revised Inventory of Grief.

RESULTS

Main findings indicated that the burden was higher in parents of adolescents with a more severe AN; fathers' burden was also significantly and positively related to their own level of anxiety. Parental grief was higher when adolescents' clinical state was more severe. Paternal grief was related to higher anxiety and depression, while maternal grief was correlated to higher alexithymia and depression. Paternal burden was explained by the father's anxiety and grief, maternal burden by the mother's grief and her child's clinical state.

CONCLUSION

Parents of adolescents suffering from AN showed high levels of burden, emotional distress and grief. These inter-related experiences should be specific targets for intervention aimed at supporting parents. Our results support the extensive literature on the need to assist fathers and mothers in their caregiving role. This in turn may improve both their mental health and their abilities as caregivers of their suffering child.
