Effects of community-based educational video interventions on nutrition, health, and use of health services in low- and middle-income countries: systematic review and meta-analysis.

CONTEXT: Health education using videos has been promoted for its potential to enhance community health by improving social and behavior change communication. OBJECTIVE: To provide stakeholders in maternal and child health with evidence that can inform policies and strategies integrating video education to improve maternal, newborn, and child health. DATA SOURCES: Five databases (MEDLINE, Embase, Scopus, Web of Science, and CENTRAL) were searched on January 28, 2022, and November 10, 2022 (updated search). Quantitative and qualitative studies conducted in low- and middle-income countries on the effects of video-based interventions on nutrition, health, and health service use were eligible. There was no restriction on time or language. Study selection was done in 2 stages and in duplicate. DATA EXTRACTION: A total of 13 710 records were imported to EndNote. Of these, 8226 records were screened by title and abstract using Rayyan, and 76 records were included for full-text evaluation. RESULTS: Twenty-nine articles (n = 12 084 participants) were included in this systematic review, and 7 were included in the meta-analysis. Video interventions improved knowledge about newborn care (n = 234; odds ratio [OR], 1.20; 95% confidence interval [CI], 1.04-1.40), colostrum feeding (n = 990; OR, 60.38; 95%CI, 18.25-199.78), continued breastfeeding (BF; n = 1914; OR, 3.79; 95%CI, 1.14-12.64), intention to use family planning (FP) (n = 814; OR, 1.57; 95%CI, 1.10-2.23), and use of FP (n = 864; OR, 6.55; 95%CI, 2.30-18.70). Video interventions did not result in reduced prelacteal feeding or improvement in early initiation of BF. The qualitative studies showed that video interventions were acceptable and feasible, with perceived impacts on communities. CONCLUSION: This systematic review and meta-analysis indicated that video interventions improved knowledge of newborn care, colostrum feeding, and continuing BF, and the intention to use FP. Given the high levels of heterogeneity and inconsistency in reporting, more research with stronger designs is recommended. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42022292190.

Association between urbanization and metabolic syndrome in low- and middle-income countries: A systematic review and meta-analysis.

AIMS: The prevalence of metabolic syndrome (MetS) is on the rise in an increasingly urbanized world. The study aimed to review the association between urbanization and MetS in low- and middle-income countries (LMICs). DATA SYNTHESIS: A comprehensive search of five databases (MEDLINE, Web of Science, Scopus, EMBASE, and CENTRAL) was performed in January 2022 and updated in October 2022. Peer-reviewed studies that met the eligibility selection criteria were included. Search terms were used for the main concepts which are MetS, dietary patterns, and urbanization in LMICs. Study selection was done in two stages and in duplicate. Random effects models were used to calculate the overall pooled prevalence and main study-level characteristics. Out of 9,773 identified studies, nineteen were included in the systematic review and meta-analysis. The studies were done on 313,644 participants (149,616 urban and 164,028 rural). The pooled risk ratio (RR, 95% confidence interval) of MetS between urban and rural dwellers was RR = 1.24; 95%CI [1.15, 1.34] (I2 = 96.0%, P < 0.0001). A relatively higher prevalence of MetS among urban than rural residents has been observed, especially with the International Diabetes Federation criteria (RR = 1.54; 95%CI [1.21, 1.96]; I2 = 65.0%), and in the population in India (RR = 2.19; 95%CI = 1.24, 3.88, I2 = 85%). Overall, the role of dietary patterns in the development of MetS was inconsistent, and few studies showed a lower risk of MetS with adherence to recommended healthy dietary patterns. CONCLUSIONS: There was an association between urbanization and the high prevalence of MetS. Interventions and policies to reduce the risk of MetS are needed.

Systematic review: Glycomics as diagnostic markers for hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer with one of the highest cancer-related mortality rates worldwide. Early diagnosis is crucial for improving the therapeutic options and reducing the disease-related mortality. AIM: To investigate serum N-glycomics as diagnostic markers for HCC. METHODS: We performed a comprehensive search in PubMed, EMBASE, Web of Science and Scopus through August 17, 2023. Eligible studies assessed the potential use of serum N-glycomics as diagnostic biomarkers for HCC. Study selection, data extraction and quality assessment were performed by two independent reviewers. RESULTS: Of the 48 articles included, 11 evaluated the utility of N-glycomics for the diagnosis of HCC in whole serum while the remaining articles focused on specific protein glycoforms or protein levels. Of these specific proteins, haptoglobin, alpha-fetoprotein (AFP), kininogen (Kin), α-1-antitrypsin and Golgi protein 73 (GP73) were the most frequently studied. Increased levels of fucosylation and branching presented as the most prevalent post-translational modifications of glycoproteins in patients with HCC compared to controls. Notably, glycomics-based biomarkers may provide a clinical benefit for the diagnosis of early HCC, as several algorithms achieved AUCs between 0.92-0.97. However, these were based on single studies with limited sample sizes and should therefore be validated. CONCLUSIONS: Alterations in serum N-glycomics, characterised by increased levels of fucosylation and branching, have potential as diagnostic biomarkers for HCC. Optimisation of study design, patient selection and analysing techniques are needed before clinical implementation will be possible.

Impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review.

BACKGROUND: Cardiovascular diseases remain the foremost global cause of death. The COVID-19 pandemic has strained health-care systems, leading to delays in essential medical services, including treatment for cardiovascular diseases. We aimed to examine the impact of the pandemic on delayed cardiovascular care in Europe. METHODS: In this systematic review, we searched PubMed, Embase, and Web of Science for peer-reviewed and published quantitative studies in English from Nov 1, 2019, to Sept 18, 2022, that addressed pandemic-induced delays in cardiovascular disease care for adult patients in Europe. Data appraisal, extraction, and quality assessment were done by two reviewers using the 14-item QualSyst tool checklist. We extracted summary patient-level data from the studies, including around 3·5 million patients. Evaluated outcomes included changes pre-March 2020 and during the COVID-19 pandemic in hospital admissions, mortality rates, medical help-seeking delays post-symptom onset, treatment initiation delays, and treatment procedure counts. The protocol is registered on PROSPERO (CRD42022354443). FINDINGS: Of the 132 included studies (20% from the UK), all were observational retrospective, with 87% focusing on the first wave of the pandemic. Results were categorised into five disease groups: ischaemic heart diseases, cerebrovascular diseases, cardiac arrests, heart failures, and others. Hospital admissions showed significant decreases around the ranges of 12-66% for ischaemic heart diseases, 9-40% for cerebrovascular diseases, 9-66% for heart failures, 27-88% for urgent and elective cardiac procedures, and an increase between 11-56% for cardiac arrests. Mortality rates were significantly higher during the pandemic, ranging between 1-25% (vs 16-22% before the pandemic) for ischaemic heart diseases and 8-70% (vs 8-26% before the pandemic) for cerebrovascular diseases. Only one study ranked low in quality. INTERPRETATION: The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Policymakers and health-care systems should work together on implementing adequate resource allocation strategies and clear guidelines on how to handle care during health crises, reducing diagnosis and treatment initiation delays, and promoting a healthy lifestyle. Future studies should evaluate the long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19. FUNDING: Belgian Science Policy Office.

The impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review.

AIMS: Cardiovascular diseases (CVD) are the leading cause of death worldwide. The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems, causing delays in essential medical services, and potentially impacting CVD treatment. This study aims to estimate the impact of the pandemic on delayed CVD care in Europe by providing a systematic overview of the available evidence. METHODS AND RESULTS: PubMed, Embase, and Web of Science were searched until mid-September 2022 for studies focused on the impact of delayed CVD care due to the pandemic in Europe among adult patients. Outcomes were changes in hospital admissions, mortality rates, delays in seeking medical help after symptom onset, delays in treatment initiation, and change in the number of treatment procedures. We included 132 studies, of which all were observational retrospective. Results were presented in five disease groups: ischaemic heart diseases (IHD), cerebrovascular accidents (CVA), cardiac arrests (CA), heart failures (HF), and others, including broader CVD groups. There were significant decreases in hospital admissions for IHD, CVA, HF and urgent and elective cardiac procedures, and significant increases for CA. Mortality rates were higher for IHD and CVA. CONCLUSION: The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Adequate resource allocation, clear guidelines on how to handle care during health crises, reduced delays, and healthy lifestyle promotion should be implemented. The long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19 should be further evaluated.

Effects of iron supplementation on cognitive development in school-age children: Systematic review and meta-analysis.

BACKGROUND: Iron deficiency is negatively associated with children's cognitive development. Evidence showed that iron supplementation improves cognitive development. Nearly 50% of anemia is caused by iron deficiency. Anemia affects more school-age children, at an age where their brain development continues. The aim of this systematic review and meta-analysis is to review the evidence from published randomized controlled trials to evaluate the effects of iron supplementation on cognitive development and function among school-age children. METHOD: Five databases including MEDLINE, EMBASE, Scopus, Web of Science and CENTRAL were used to search for articles on April 20th, 2021. The search was reconducted on October 13th, 2022 to retrieve new records. Studies were eligible if they included school children 6-12 years of age, were randomized controlled trials, and if they tested iron supplementation and measured cognitive development. RESULT: Thirteen articles were included in the systematic review. Overall, iron supplementation significantly improved intelligence (standardized mean difference, 95% confidence interval) (SMD 0.46, 95%CI: 0.19, 0.73, P<0.001), attention and concentration (SMD 0.44, 95%CI: 0.07, 0.81, P = 0.02) and memory (SMD 0.44, 95%CI: 0.21, 0.67, P <0.001) of school-age children. There was no significant effect of iron supplementation on school achievement of school-age children (SMD 0.06, 95%CI: -0.15, 0.26, P = 0.56). In a subgroup analysis, iron-supplemented children who were anemic at baseline had had better outcomes of intelligence (SMD 0.79, 95%CI: 0.41, 1.16, P = 0.001) and memory (SMD 0.47, 95%CI: 0.13, 0.81; P = 0.006). CONCLUSION: Iron supplementation has a significant positive effect on the intelligence, attention and concentration, and the memory of school-age children but there was no evidence on the effect of iron supplementation on their school achievement.

Meta-analysis: The impact of light-to-moderate alcohol consumption on progressive non-alcoholic fatty liver disease.

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is defined as fatty liver disease in the absence of heavy alcohol consumption. However, the impact of light-to-moderate alcohol consumption on progressive NAFLD and on mortality is presently unclear. METHODS: Medline, Embase, OATD and OpenGrey were systematically searched up to November 2022 for relevant cross-sectional, case-control and cohort studies. The study outcomes were progressive NAFLD-steatohepatitis (NASH), fibrosis, cirrhosis, hepatocellular carcinoma (HCC) and mortality. The entire review process was performed by two independent reviewers. A narrative synthesis was performed for all outcomes, while meta-analyses, subgroup analyses and publication bias assessment were performed depending on the number of articles. RESULTS: After study selection, 32 articles were included. Cohort studies reported that moderate alcohol intake increased the risk for advanced fibrosis (pooled OR 1.56; 95% CI 1.08-2.26 and HR 1.39; 95% CI 1.22-1.57), which was not observed in cross-sectional studies. Alcohol use also increased the risk of developing liver cirrhosis and HCC, but seemed to lower the risk of steatohepatitis. Light alcohol consumption protected against all-cause mortality, an effect not observed in NAFLD patients with moderate intake. CONCLUSIONS: There is wide heterogeneity in studies on the impact of alcohol on progressive NAFLD. Nevertheless, cohort studies reported a significant harmful effect of moderate alcohol consumption on the occurrence of advanced fibrosis. Further research is needed to make valid recommendations with regard to alcohol consumption in patients with NAFLD.

Image analysis systems to calculate the surface area of vitiligo lesions: A systematic review of measurement properties.

Several digital image analysis systems have been developed for surface calculation of vitiligo lesions. Critical assessment of their measurement properties is crucial to support evidence-based recommendations on the most suitable instruments and will reveal the need for future research. A systematic review was performed to systematically summarize, compare, and critically assess the measurement properties of digital and analogue analysis systems for surface calculation of vitiligo lesions following the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations. Nineteen clinical trials were selected including 25 different instruments. Manual tracing on transparent sheets (contact planimetry) combined with digital measurement or point counting can be considered as the best validated method for the evaluation of target lesions taking into account the skin curvatures. Two-dimensional digital imaging analysis on photographs seems also robust although confirmatory data of different research groups using the same digital instrument in a wide range of skin types are missing. Analysis based on 3D photography is still in its early stage but is promising for whole-body analysis. However, the reported data on the quality of the instruments for surface area calculation of vitiligo lesions were in general rather limited. Therefore, future high-quality validation studies are required also including full body evaluations.

Patient-Relevant Outcomes in Psoriasis: A Systematic Review.

Importance: There is a need to define which outcomes matter to patients with psoriasis to deliver value for the patient when managing their condition. Objectives: To generate a comprehensive overview of all outcomes relevant in the management of psoriasis as defined by patients. Evidence Review: A systematic review was performed by searching 3 databases (MEDLINE, Embase, and Web of Science) from August 1, 2019, until March 27, 2021, using a comprehensive search strategy consisting of 4 concepts including psoriasis, patients, outcomes, and relevance. A (citing) reference search was also performed of all retrieved articles. Two independent reviewers screened the retrieved records by title/abstract against the eligibility criteria. Studies were eligible for inclusion if they reported on the importance of outcomes for patients with psoriasis. No language restrictions were used. Data extraction and quality assessment were also performed independently. Quality assessment was done using the QUALSYST tool. Findings: In total, 10 365 records were screened for eligibility, of which 24 studies were included for synthesis. A total of 23 317 patients were evaluated, and 273 (154 unique) items were retrieved. These items were aggregated into 23 outcomes: (almost) complete clearance; symptom control; difficult location clearance; time to clearance; treatment efficacy, sustainability, safety, tolerability, and convenience; comorbidity control; daily and social activity; emotional well-being; intimate relationships; productivity; health-related quality of life; confidence in care; control of disease; communication with care professional; information from other sources than care professional; and cost of care (societal and for the patient). These were then further grouped into 4 core areas: physical/clinical, life impact, resource use, and adverse effects. The mean overall quality of the studies was 75.6% (range, 35.7%-100%). Conclusions and Relevance: This systematic review analyzed patient-relevant outcomes reported in patients with psoriasis to aid in the transition to a value-based treatment approach.

Work environment risk factors causing day-to-day stress in occupational settings: a systematic review.

BACKGROUND: While chronic workplace stress is known to be associated with health-related outcomes like mental and cardiovascular diseases, research about day-to-day occupational stress is limited. This systematic review includes studies assessing stress exposures as work environment risk factors and stress outcomes, measured via self-perceived questionnaires and physiological stress detection. These measures needed to be assessed repeatedly or continuously via Ecological Momentary Assessment (EMA) or similar methods carried out in real-world work environments, to be included in this review. The objective was to identify work environment risk factors causing day-to-day stress. METHODS: The search strategies were applied in seven databases resulting in 11833 records after deduplication, of which 41 studies were included in a qualitative synthesis. Associations were evaluated by correlational analyses. RESULTS: The most commonly measured work environment risk factor was work intensity, while stress was most often framed as an affective response. Measures from these two dimensions were also most frequently correlated with each other and most of their correlation coefficients were statistically significant, making work intensity a major risk factor for day-to-day workplace stress. CONCLUSIONS: This review reveals a diversity in methodological approaches in data collection and data analysis. More studies combining self-perceived stress exposures and outcomes with physiological measures are warranted.

Maternal and Perinatal Risk Factors for Pediatric Nonalcoholic Fatty Liver Disease: A Systematic Review.

BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) has become the most common pediatric liver disease. The intrauterine and early life environment can have an important impact on long-term metabolic health. We investigated the impact of maternal prepregnancy obesity, (pre)gestational diabetes, breastfeeding, and birth anthropometrics/preterm birth on the development of NAFLD in children and adolescents. METHODS: A comprehensive search was performed in MEDLINE, PubMed Central, EMBASE, and grey literature databases through August 2020. The primary outcome was the prevalence of pediatric NAFLD, whereas the histologic severity of steatohepatitis and/or fibrosis were secondary outcomes. Study selection, data extraction, and quality assessment were performed by 2 independent reviewers. RESULTS: Our systematic review included 33 articles. Study heterogeneity regarding patient populations, diagnostic tools, and overall quality was considerable. Eight studies determined the impact of maternal prepregnancy overweight/obesity and identified this as a possible modifiable risk factor for pediatric NAFLD. Conversely, 8 studies investigated (pre)gestational diabetes, yet the evidence on its impact is conflicting. Breastfeeding was associated with a reduced risk for NAFLD, steatohepatitis, and fibrosis, especially in studies that evaluated longer periods of breastfeeding. Being born preterm or small for gestational age has an unclear impact on the development of NAFLD, although an early catch-up growth might drive NAFLD. CONCLUSIONS: In a systematic review, we found that maternal prepregnancy overweight and obesity were associated with an increased risk of pediatric NAFLD. Breastfeeding might be protective against the development of NAFLD when the duration of breastfeeding is sufficiently long (≥6 months).

A systematic review of quality improvement initiatives for continuous sedation until death.

BACKGROUND: Extensive debate surrounds the practice of continuous sedation until death within end-of-life care. AIM: To provide insight into existing initiatives to support the practice of continuous sedation until death and assess their feasibility and effectiveness. DESIGN: Systematic review and narrative synthesis, registered on PROSPERO (CRD42020149630). DATA SOURCES: Records were searched through MEDLINE, EMBASE, CENTRAL, CINAHL, and Web of Science from inception to April 16 2020. Peer-reviewed studies reporting original data on initiatives to support the practice of continuous sedation were included for review. RESULTS: Twenty-one studies met the criteria and were included. Initiatives were focused on assessment tools of consciousness and discomfort (9), the use of guidelines and protocols (8), and expert consultation (3). All initiatives were reported as useful, acceptable, and feasible. Studies on the use of monitoring devices showed that a small proportion of patients were found to be awake, despite the patient being unresponsive according to the observer-based sedation scales. However, the wide range of values of these monitoring devices for comfortable and adequately sedated patients seems to hamper its overall implementation in daily clinical practice. Physicians reported changes in practice conform to guideline recommendations but the shift was modest at best. Expert consultation was regarded as supportive when sufficient expertise is lacking and helpful in avoiding possibly unnecessary sedations. CONCLUSIONS: The reviewed initiatives may contribute to improvement of continuous sedation until death, though their evidence base is rather limited. More insight is needed into their feasibility, preconditions for effective implementation and impact in actual practice.

Healthcare interventions improving and reducing quality of life in children at the end of life: a systematic review.

BACKGROUND: Children with serious illness suffer from symptoms at the end of life that often fail to be relieved. An overview is required of healthcare interventions improving and decreasing quality of life (QOL) for children with serious illness at the end of life. METHODS: A systematic review was performed in five databases, January 2000 to July 2018 without language limit. Reviewers selected quantitative studies with a healthcare intervention, for example, medication or treatment, and QOL outcomes or QOL-related measures, for example, symptoms, for children aged 1-17 years with serious illness. One author assessed outcomes with the QualSyst and GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) Framework; two authors checked a 25% sample. QOL improvement or reduction was categorized. RESULTS: Thirty-six studies met the eligibility criteria studying 20 unique interventions. Designs included 1 randomized controlled trial, 1 cross-sectional study, and 34 cohort studies. Patient-reported symptom monitoring increased QOL significantly in cancer patients in a randomized controlled trial. Dexmedetomidine, methadone, ventilation, pleurodesis, and palliative care were significantly associated with improved QOL, and chemotherapy, stem cell transplant, and hospitalization with reduced QOL, in cohort studies. CONCLUSIONS: Use of patient-controlled symptom feedback, multidisciplinary palliative care teams with full-time practical support, inhalation therapy, and off-label sedative medication may improve QOL. Curative therapy may reduce QOL. IMPACT: QOL for children at the end of life may be improved with patient-controlled symptom feedback, multidisciplinary palliative care teams with full-time practical support, inhalation therapy, and off-label sedative medication. QOL for children at the end of life may be reduced with therapy with a curative intent, such as curative chemotherapy or stem cell transplant. A comprehensive overview of current evidence to elevate currently often-failing QOL management for children at the end of life. New paradigm-level indicators for appropriate and inappropriate QOL management in children at the end of life. New hypotheses for future research, guided by the current knowledge within the field. Various healthcare interventions (as described above) could or might be employed as tools to provide relief in QOL management for children with serious illness, such as cancer, at the end of life, and therefore could be discussed in pediatrician end-of-life training to limit the often-failed QOL management in this population, cave the one-size-fits-all approach for individual cases. Multidisciplinary team efforts and 24/7 presence, especially practical support for parents, might characterize effective palliative care team interventions for children with serious illness at the end of life, suggesting a co-regulating link between well-being of the child partly to that of the parents Hypothesis-oriented research is needed, especially for children with nonmalignant disorders, such as genetic or neurological disorders at the end of life, as well as QOL outcomes for intervention research and psychosocial or spiritual outcomes.

Magnetic resonance imaging for forensic age estimation in living children and young adults: a systematic review.

The use of MRI in forensic age estimation has been explored extensively during the last decade. The authors of this paper synthesized the available MRI data for forensic age estimation in living children and young adults to provide a comprehensive overview that can guide age estimation practice and future research. To do so, the authors searched MEDLINE, Embase and Web of Science, along with cited and citing articles and study registers. Two authors independently selected articles, conducted data extraction, and assessed risk of bias. They considered study populations including living subjects up to 30 years old. Fifty-five studies were included in qualitative analysis and 33 in quantitative analysis. Most studies had biases including use of relatively small European (Caucasian) populations, varying MR approaches and varying staging techniques. Therefore, it was not appropriate to pool the age distribution data. The authors found that reproducibility of staging was remarkably lower in clavicles than in any other anatomical structure. Age estimation performance was in line with the gold standard, radiography, with mean absolute errors ranging from 0.85 years to 2.0 years. The proportion of correctly classified minors ranged from 65% to 91%. Multifactorial age estimation performed better than that based on a single anatomical site. The authors found that more multifactorial age estimation studies are necessary, together with studies testing whether the MRI data can safely be pooled. The current review results can guide future studies, help medical professionals to decide on the preferred approach for specific cases, and help judicial professionals to interpret the evidential value of age estimation results.

Health-related quality of life overview after different curative treatment options in muscle-invasive bladder cancer: an umbrella review.

PURPOSE: This umbrella review aims to evaluate the quality, summarize and compare the conclusions of systematic reviews investigating the impact of curative treatment options on health-related quality of life (HRQoL) in muscle-invasive bladder cancer (MIBC). METHODS: The Cochrane Library, MEDLINE, Embase and Web of Science were searched independently by two authors from inception until 06 January 2020. Systematic reviews and meta-analyses assessing the impact of any curative treatment option on HRQol in MIBC patients were eligible. Risk of bias was assessed using the AMSTAR 2 tool. RESULTS: Thirty-two reviews were included. Robot-assisted RC with extracorporeal urinary diversion and open RC have similar HRQoL (n = 10). Evidence for pelvic organ-sparing RC was too limited (n = 2). Patients with a neobladder showed better overall and physical HRQoL outcomes, but worse urinary function in comparison with ileal conduit (n = 17). Bladder-preserving radiochemotherapy showed slightly better urinary and sexual but worse gastro-intestinal HRQoL outcomes in comparison with RC patients (n = 6). Quality of the reviews was low in more than 50% of the available reviews and most of the studies included in the reviews were nonrandomized studies. CONCLUSION: This umbrella review gives a comprehensive overview of the available evidence to date.

Risk factors for neonatal brachial plexus palsy: a systematic review and meta-analysis.

AIM: To provide a comprehensive update on the most prevalent, significant risk factors for neonatal brachial plexus palsy (NBPP). METHOD: Cochrane CENTRAL, MEDLINE, Web of Science, Embase, and ClinicalTrials.gov were searched for relevant publications up to March 2019. Studies assessing risk factors of NBPP in relation to typically developing comparison individuals were included. Meta-analysis was performed for the five most significant risk factors, on the basis of the PRISMA statement and MOOSE guidelines. Pooled odds ratios (ORs), 95% confidence intervals (CIs), and across-study heterogeneity (I2 ) were reported. Reporting bias and quality of evidence was rated. In addition, we assessed the incidence of NBPP. RESULTS: Twenty-two observational studies with a total sample size of 29 419 037 live births were selected. Significant risk factors included shoulder dystocia (OR 115.27; 95% CI 81.35-163.35; I2 =92%), macrosomia (OR 9.75; 95% CI 8.29-11.46; I2 =70%), (gestational) diabetes (OR 5.33; 95% CI 3.77-7.55; I2 =59%), instrumental delivery (OR 3.8; 95% CI 2.77-5.23; I2 =77%), and breech delivery (OR 2.49; 95% CI 1.67-3.7; I2 =70%). Caesarean section appeared as a protective factor (OR 0.13; 95% CI 0.11-0.16; I2 =41%). The pooled overall incidence of NBPP was 1.74 per 1000 live births. It has decreased in recent years. INTERPRETATION: The incidence of NBPP is decreasing. Shoulder dystocia, macrosomia, maternal diabetes, instrumental delivery, and breech delivery are risk factors for NBPP. Caesarean section appears as a protective factor. WHAT THIS PAPER ADDS: The overall incidence of neonatal brachial plexus palsy is 1.74 per 1000 live births. The incidence has declined significantly. Shoulder dystocia, macrosomia, maternal diabetes, instrumental delivery, and breech delivery are the main risk factors. Prevention is difficult owing to unpredictability and often labour-related risk.

A comprehensive catalogue of EQ-5D scores in chronic disease: results of a systematic review.

PURPOSE: Chronic diseases are associated with impaired health-related quality of life (HRQoL) outcomes. Comparison of HRQoL outcomes between different diseases and with the general population is of major importance to health economists, epidemiologists, clinicians, and policy makers. The aim of this systematic literature review was to develop a catalogue with EQ-5D scores in chronic non-communicable diseases, and to compare these scores with reference values from the general population. METHODS: MEDLINE, Embase, and Web of Science were systematically searched independently by two reviewers. Studies were included if they reported mean EQ-5D index values for the adult population and if these scores were compared with the general population. The QualSyst tool for quantitative research was used for quality appraisal. RESULTS: Two hundred and seven articles met the inclusion criteria. An extensive catalogue summarizes the EQ-5D scores in a wide variety of chronic diseases. Mean EQ-5D index values ranged between - 0.20 and 1. Lower EQ-5D scores are reported in chronic diseases compared to the general population, specifically in neurological disorders. Most of the diseases demonstrate a substantial disutility, although a minority of diseases have equal or even higher index scores than the general population. CONCLUSION: A comprehensive, international catalogue has been developed to provide EQ-5D index scores for diverse chronic diseases compared with reference values based on the available literature. The catalogue gives a clear overview of the existing EQ-5D scores and can be rapidly accessed by researchers worldwide for different applications such as health economic evaluations, decision making, resource allocation, and other policy objectives. Future studies should focus on unexamined diseases and specific patient groups to expand the evidence base on HRQoL in chronic diseases.

Influence of health interventions on quality of life in seriously ill children at the end of life: a systematic review protocol.

BACKGROUND: Seriously ill children suffer from numerous symptoms at the end of their lives, including pain, anxiety, and restricted communication. There are currently no comprehensive overviews of which health interventions have proven benefits and which have proven detrimental effects on the quality of life of children in an end-of-life context. In order to identify potential quality indicators to eventually improve care, a systematic review of available evidence is needed. The aim of the current systematic review will be to make an overview of the influence of health interventions on associated outcomes related to quality of life at the end of life in seriously ill children. METHODS: A systematic search will be conducted in MEDLINE, Embase, CENTRAL, CINAHL, and Web of Science. We will include quantitative empirical designs looking into the influence of a health intervention on (proxies of) quality of life at the end of life in seriously ill children. Three independent authors will review titles and abstracts and screen full texts against eligibility criteria. One reviewer will carry out full data extraction and quality assessment, and a 20% random sample will be extracted and assessed by two independent reviewers. We will use the QualSyst Tool for assessment of the quality of the included studies (QualSyst Tool) for quality assessment; overall strength of the body of evidence will be assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. An overview table of health interventions will be discussed through narrative synthesis. Should sufficient homogeneous publications arise, we will perform meta-analyses with a random-effects model.
