Review
Gastrointestinal(GI) endoscopy forms a significant proportion of clinicians' workloads. However, little attention is given to the ergonomic aspects of endoscopy. This systematic review of musculoskeletal pain and/or injuries in GI endoscopists aims to better understand the types of occupational injuries resulting from endoscopic procedures and associated risk factors. Areas covered: Systematic literature search conducted for articles evaluating prevalence, risk factors and mechanism of musculoskeletal pain and/or injuries related to GI endoscopy. In 13 included studies, 39-89% of surveyed endoscopists reported pain and/or injuries related to endoscopy. Common areas of pain were the back(15-57%), neck(9-46%), shoulders(9-19%), elbows(8-15%) and hands/fingers(14-82%). Risk factors included procedure volume, time spent doing endoscopy, cumulative time in practice and endoscopist age. Experimental studies showed that forces and loads placed on endoscopists' bodies during procedures place them at risk of occupational injury. Areas of pain differed between novice and experienced endoscopists implying separate mechanisms of injury. Expert commentary: Comprehensive investigation into the prevalence, types, pathophysiology and methods to minimise endoscopy-related musculoskeletal injuries is vital to ensure the continued efficient provision of endoscopy services in the face of rising demands worldwide. A paradigm shift is required in endoscopic devices and techniques to improve safety and comfort.

Meta-Analysis
BACKGROUND
Prisons are recognised as high-risk environments for tuberculosis, but there has been little systematic investigation of the global and regional incidence and prevalence of tuberculosis, and its determinants, in prisons. We did a systematic review and meta-analysis to assess the incidence and prevalence of tuberculosis in incarcerated populations by geographical region.
METHODS
In this systematic review and meta-analysis, we searched MEDLINE, Embase, Web of Knowledge, and the LILACS electronic database from Jan 1, 1980, to Nov 15, 2020, for cross-sectional and cohort studies reporting the incidence of Mycobacterium tuberculosis infection, incidence of tuberculosis, or prevalence of tuberculosis among incarcerated individuals in all geographical regions. We extracted data from individual studies, and calculated pooled estimates of incidence and prevalence through hierarchical Bayesian meta-regression modelling. We also did subgroup analyses by region. Incidence rate ratios between prisons and the general population were calculated by dividing the incidence of tuberculosis in prisons by WHO estimates of the national population-level incidence.
FINDINGS
We identified 159 relevant studies; 11 investigated the incidence of M tuberculosis infection (n=16 318), 51 investigated the incidence of tuberculosis (n=1 858 323), and 106 investigated the prevalence of tuberculosis (n=6 727 513) in incarcerated populations. The overall pooled incidence of M tuberculosis infection among prisoners was 15·0 (95% credible interval [CrI] 3·8-41·6) per 100 person-years. The incidence of tuberculosis (per 100 000 person-years) among prisoners was highest in studies from the WHO African (2190 [95% CrI 810-4840] cases) and South-East Asia (1550 [240-5300] cases) regions and in South America (970 [460-1860] cases), and lowest in North America (30 [20-50] cases) and the WHO Eastern Mediterranean region (270 [50-880] cases). The prevalence of tuberculosis was greater than 1000 per 100 000 prisoners in all global regions except for North America and the Western Pacific, and highest in the WHO South-East Asia region (1810 [95% CrI 670-4000] cases per 100 000 prisoners). The incidence rate ratio between prisons and the general population was much higher in South America (26·9; 95% CrI 17·1-40·1) than in other regions, but was nevertheless higher than ten in the WHO African (12·6; 6·2-22·3), Eastern Mediterranean (15·6; 6·5-32·5), and South-East Asia (11·7; 4·1-27·1) regions.
INTERPRETATION
Globally, people in prison are at high risk of contracting M tuberculosis infection and developing tuberculosis, with consistent disparities between prisons and the general population across regions. Tuberculosis control programmes should prioritise preventive interventions among incarcerated populations.

Review
BACKGROUND
Population-based prevalence and incidence studies are essential for understanding the societal burden of dementia with Lewy bodies (DLB).
METHODS
The MEDLINE and EMBASE databases were searched to identify publications addressing the incidence and/or prevalence of DLB. References of included articles and prior systematic reviews were searched for additional studies. Two reviewers screened all abstracts and full-text reviews, abstracted data and performed quality assessments.
RESULTS
Twenty-two studies were included. Incidence rates ranged from 0.5 to 1.6 per 1000 person-years. DLB accounted for 3.2-7.1% of all dementia cases in the incidence studies. Point and period prevalence estimates ranged from 0.02 to 63.5 per 1000 persons. Increasing prevalence estimates were reported with increasing age. DLB accounted for from 0.3 to 24.4% of all cases of dementia in the prevalence studies.
CONCLUSIONS
DLB becomes more common with increasing age and accounts for about 5% of all dementia cases in older populations.

Meta-Analysis
Thoracic aortic aneurysms (TAA) may grow asymptomatically until they rupture, with a mortality over 90%. The true incidence and prevalence of this condition is uncertain and epidemiologic data is scarce, understudied and dispersed. Therefore, we aimed to conduct a systematic review and meta-analysis of the incidence and prevalence of TAAs in population-based studies. We searched MEDLINE, EMBASE and CENTRAL from inception to October 2020 for all population-based studies reporting on incidence and/or prevalence of TAAs. Data were pooled using a random effects model. The main outcome was the overall available worldwide incidence and prevalence of TAAs. The secondary outcomes were to evaluate the incidence of ruptured TAAs, differences in the location of these aneurysms (either ascending, arch or descending aorta) and differences in prevalence/incidence across different study designs. Twenty-two studies were included in the review and meta-analysis. The pooled incidence and prevalence of TAAs was 5.3 per 100,000 individuals/year (95% confidence interval [CI]: 3.0; 8.3) and 0.16% (95% CI: 0.12; 0.20), respectively. The pooled incidence of ruptured aneurysms was 1.6 per 100,000 individuals/year (95% CI: 1.3; 2.1). We found a significant difference of the prevalence in autopsy-only studies, which was 0.76% (95% CI: 0.47; 1.13) and the prevalence of TAAs dropped down to 0.07% (95% CI: 0.05;0.11) when these studies were excluded from the overall analysis. The current epidemiologic information provided serve as a base for future public-health decisions. The lack of well-design population-base studies and the limitations encountered serve as calling for future research in this field.

Review
BACKGROUND & AIMS
The aim of this study was to quantify the global epidemiology of primary sclerosing cholangitis (PSC), alongside the incidence of liver transplantation, cancer, and death, through robust systematic review of population-based data.
METHODS
We searched MEDLINE and EMBASE up to and including June 30, 2020 to identify population-based studies reporting the incidence and/or prevalence of PSC. Studies that did not report original data, or of exclusively pediatric-onset disease (diagnosis age <16 years) or exclusively PSC-associated with inflammatory bowel disease were excluded.
RESULTS
Of 4922 published studies, 17 fulfilled inclusion criteria; 16 documenting incidence and 14 prevalence. The highest reported incidence of PSC was reported in Northern Europe (Finland, 1.58 and Norway, 1.3 per-100,000 population, respectively) and North America (Minnesota, 1.47); with the lowest being observed across the Mediterranean Basin (Italy, 0.1). Prevalence ranged from 31.7 in Finland and 23.99 in Minnesota, to 1.33 in Singapore and 0.0 in Alaska. Of studies reporting temporal occurrence, an increase in disease incidence was observed across North America and Northern Europe (4 studies), alongside an increase in prevalence over time (4 studies). The incidence and risks for clinical outcomes were presented by 9 of the included studies. Median transplant-free survival ranged from 9.7 (United States) to 20.6 years (Netherlands), with standardized mortality ratios of 2.5 and 4.2 compared with the control population. The standardized incidence of cholangiocarcinoma ranged from 235 (Finland) to 398 (Netherlands).
CONCLUSIONS
Estimates of PSC incidence and prevalence vary, with most studies conducted in North America and Western Europe; the latter showing a steady increase in disease occurrence over time. Further research is needed to understand changes in disease epidemiology, including etiological drivers, the implications of rising case burden on health care policy, and better appreciation of PSC in the developing world.

The Canadian Journal of Neurological... Apr 2016Population-based prevalence and incidence studies are essential for understanding the burden of frontotemporal dementia (FTD). (Review)
Review
BACKGROUND
Population-based prevalence and incidence studies are essential for understanding the burden of frontotemporal dementia (FTD).
METHODS
The MEDLINE and EMBASE databases were searched to identify population-based publications from 1985 to 2012, addressing the incidence and/or prevalence of FTD. References of included articles and prior systematic reviews were searched for additional studies. Two reviewers screened all abstracts and full-text reviews, abstracted data and performed quality assessments.
RESULTS
Twenty-six studies were included. Methodological limitations led to wide ranges in the estimates for prevalence (point prevalence 0.01-4.6 per 1000 persons; period prevalence 0.16-31.04 per 1000 persons) and incidence (0.0-0.3 per 1000 person-years). FTD accounted for an average of 2.7% (range 0-9.1%) of all dementia cases among prevalence studies that included subjects 65 and older compared to 10.2% (range 2.8-15.7%) in studies restricted to those aged less than 65. The cumulative numbers of male (373 [52.5%]) and female (338 [47.5%]) cases from studies reporting this information were nearly equal (p=0.18). The behavioural variant FTD (bvFTD) was almost four times as common as the primary progressive aphasias.
CONCLUSIONS
Population-based estimates for the epidemiology of FTD varied widely in the included studies. Refinements in the diagnostic process, possibly by the use of validated biomarkers or limiting case ascertainment to specialty services, are needed to obtain more precise estimates of the prevalence and incidence of FTD.

Review
The objectives were (i) to conduct an overview of systematic reviews to summarize evidence from and evaluate the methodological quality of systematic reviews assessing the impact of ambient temperature on morbidity and mortality; and (ii) to reanalyse meta-analyses of cold-induced cardiovascular morbidity in different age groups. The registration number is PROSPERO-CRD42016047179. PubMed, Embase, the Cochrane Library, Web of Science, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Global Health were systematically searched to identify systematic reviews. Two reviewers independently selected studies for inclusion, extracted data, and assessed quality. The Assessment of Multiple Systematic Reviews (AMSTAR) checklist was used to assess the methodological quality of included systematic reviews. Estimates of morbidity and mortality risk in association with heat exposure, cold exposure, heatwaves, cold spells and diurnal temperature ranges (DTRs) were the primary outcomes. Twenty-eight systematic reviews were included in the overview of systematic reviews. (i) The median (interquartile range) AMSTAR scores were 7 (1.75) for quantitative reviews and 3.5 (1.75) for qualitative reviews. (ii) Heat exposure was identified to be associated with increased risk of cardiovascular, cerebrovascular and respiratory mortality, but was not found to have an impact on cardiovascular or cerebrovascular morbidity. (iii) Reanalysis of the meta-analyses indicated that cold-induced cardiovascular morbidity increased in youth and middle-age (RR=1.009, 95% CI: 1.004-1.015) as well as the elderly (RR=1.013, 95% CI: 1.007-1.018). (iv) The definitions of temperature exposure adopted by different studies included various temperature indicators and thresholds. In conclusion, heat exposure seemed to have an adverse effect on mortality and cold-induced cardiovascular morbidity increased in the elderly. Developing definitions of temperature exposure at the regional level may contribute to more accurate evaluations of the health effects of temperature.

Review
BACKGROUND
The concept of neonatal near miss has been proposed as a tool for assessment of quality of care in neonates who suffered any life-threatening condition. However, there are no internationally agreed concepts or criteria for defining or identifying neonatal near miss. The purpose of this study was to perform a systematic review of studies and markers that are able to identify neonatal near miss cases and predict neonatal mortality.
METHODS
Electronic searches were performed in the Medline, Embase and Scielo databases, with no time or language restriction, until December 2014. The term "neonatal near miss" was used alone or in combination with terms related to neonatal morbidity/mortality and neonatal severity scores. Study selection criteria involved three steps: title, abstract and full text of the articles. Two researchers performed study selection and data extraction independently. Heterogeneity of study results did not permit the performance of meta-analysis.
RESULTS
Following the inclusion and exclusion criteria adopted, only four articles were selected. Preterm and perinatal asphyxia were used as near miss markers in all studies. Health indicators on neonatal morbidity and mortality were extracted or estimated. The neonatal near miss rate was 2.6 to 8 times higher than the neonatal mortality rate.
CONCLUSIONS
Pragmatic and management criteria are used to help develop the neonatal near miss concept. The most severe cases are identified and mortality is predicted with these criteria. Furthermore, the near miss concept can be used as a tool for evaluating neonatal care. It is the first step in building management strategies to reduce mortality and long-term sequelae.

Meta-Analysis Review
Recurrent miscarriage (RM) affects up to 2.5% of couples of reproductive age. Up to 10% of couples using assisted reproductive technology experience recurrent implantation failure (RIF). Immunosuppressive drugs, such as calcineurin inhibitors (CNIs), has been proposed for RM and RIF management. This systematic review and meta-analysis (SRMA) aimed to evaluate the efficacy and safety of CNIs in RM and RIF treatment. We searched in the three databases. Review Manager 5.4.1 was used for statistical analysis. This review included 8 studies involving 1042 women (485 women in the CNIs group and 557 women in the control group). CNI treatment (cyclosporine [CsA] and tacrolimus [TAC]) increases live birth rate (LBR, odds ratio [OR]: 2.52; 95% confidence interval [CI]: 1.93-3.28, p < 0.00001) and clinical pregnancy rate (OR: 2.25; 95% CI: 1.54-4.40, p < 0.0001) and decreases miscarriage rate (OR: 0.45 95% CI: 0.32-0.63, p < 0.00001) when compared to the control. Side effects and obstetric and neonatal complications was similar in both groups. In conclusion, CNIs increased LBR in women with RM and RIF but there is a moderate risk of bias. Subgroup analysis revealed that CNIs improved LBR in women with RM with a low risk of bias. However, in women with RIF, with moderate to high risk of bias. The use of CsA and TAC, in low doses and for a short period, for managing reproductive failures in women seems to be safe, not causing serious side effects nor increasing the risk of obstetric and neonatal complications.

Meta-Analysis Review
AIM
To assess the prevalence and incidence of chronic conditions among adults with cerebral palsy (CP) and compare them to the prevalence and incidence among adults without CP.
METHOD
We searched MEDLINE and Embase for studies reporting the prevalence or incidence of one or more chronic conditions among adults with CP. Two independent reviewers screened titles, abstracts, and full-text articles. Two independent reviewers extracted data relating to prevalence and incidence and appraised study quality. We performed random-effects meta-analyses to pool prevalence and incidence.
RESULTS
We identified 69 studies; 65 reported the prevalence of 53 conditions and 13 reported the incidence of 21 conditions. At least 20% of adults had the following conditions: depression (21%); anxiety (21%); mood affective disorders (23%); asthma (24%); hypertension (26%); epilepsy (28%); urinary incontinence (32%); malnutrition (38%); and scoliosis (46%). Adults with CP were more likely to have type 2 diabetes, anxiety, bipolar disorder, depression, schizophrenia, hypertension, ischaemic heart disease, stroke, cerebrovascular disease, asthma, liver disease, osteoarthritis, osteoporosis, underweight, and chronic kidney disease than adults without CP.
INTERPRETATION
These data from 18 countries, which provide an international perspective, may be used to promote awareness, identify targets for intervention, and inform the development of appropriate supports for adults with CP.
