Review
Introduction: Cervical cancer rates vary across the world, being highest in Eastern Africa (including Zimbabwe) and lowest in Western Asia. It is the second most common type of cancer in women in the South East Asia region and a major cause of cancer deaths among women of low and middle income countries (LMICs) like Nepal. This review is an attempt to make a comprehensive report of prevalence, incidence and mortality of cervical cancer in LMICs. Methods: The review was conducted applying a computerized search with the Medical Subject Heading (MeSH) major topics “Cervical Cancer”, “Cervical neoplasm” “Epidemiology”, (“prevalence” OR “incidence” OR “mortality”) and “HPV” OR “Human papillomavirus” as MeSH subheading. The search limits were: language (“English”), LMICs, dates (articles published from “1st January 2000 to 31st December 2015”), and species (“Humans”). The search was supplemented by cross-referencing. Publications that met the inclusion criteria were included in the synthesis. Results: Among the 20 studies reviewed; seven were from Africa, seven from Asia, three from South America, and one each from North America, Europe and Oceania. The review found the highest reported age standardized incidence rate as 17.9/100,000/year in Zimbabwe in 2000 and the lowest as 0.11/100,000/year in China in 2006. One study of Nigeria revealed a cervical cancer prevalence of 5.0 per 1,000 in 2012 in the 25-64 year age group. Further, the highest reported age standardized mortality rate was 16/100,000/year in India in 2015 and the lowest 1.8/100,000/year in Colombia in 2013. In addition, coitarche, tobacco smoking, number of sexual partners and family history of cervical cancer were reported as significant risk factors. Conclusion: The study provides a review of reported prevalence, incidence and mortality of cervical cancer in LMICs from 1st January 2000 to 31st December 2015. The scarcity of information reveals a substantial need for further studies on cervical cancer prevalence, incidence and mortality with associated risk factors in LMICs.

JAMA Dermatology Apr 2020The association between psoriasis and risk of cancer remains debatable. (Meta-Analysis)
Meta-Analysis
IMPORTANCE
The association between psoriasis and risk of cancer remains debatable.
OBJECTIVE
To evaluate the association and risk of cancer in patients with psoriasis or psoriatic arthritis, including risk of specific cancer subtypes.
DATA SOURCES
Two databases (PubMed and Embase) were screened from inception to January 1, 2019, using the search string psoriasis or psoriatic and neoplasms or malignancy or cancer. The search was filtered to only include human participants and publications in English.
STUDY SELECTION
Observational cohort studies with a population of patients with psoriasis or psoriatic arthritis were included. Studies had to be original and report the incidence or prevalence of cancer within this population. Studies evaluating pediatric populations and cancer types not included in the protocol were excluded.
DATA EXTRACTION AND SYNTHESIS
This study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The search string, objectives, and study protocol methods were defined before the study was initiated. A total of 365 studies were included for full-text assessment. Owing to the heterogeneity of the included studies, a random-effects model was used.
MAIN OUTCOMES AND MEASURES
Main outcome was cancer (overall and specific subtypes) and measures were prevalence, incidence, and risk estimate for cancer in patients with psoriasis or psoriatic arthritis.
RESULTS
Of the 365 studies assessed, 112 were included in the analysis (N = 2 053 932 patients). The overall prevalence of cancer in patients with psoriasis was 4.78% (95% CI, 4.02%-5.59%), with an incidence rate of 11.75 per 1000 person-years (95% CI, 8.66-15.31) and a risk ratio (RR) of 1.21 (95% CI, 1.11-1.33). There was an increased risk of several cancers, including keratinocyte cancer (RR, 2.28; 95% CI, 1.73-3.01), lymphomas (RR, 1.56; 95% CI, 1.37-1.78), lung cancer (RR, 1.26; 95% CI, 1.13-1.40), and bladder cancer (RR, 1.12; 95% CI, 1.04-1.19). No increased risk of cancer for patients with psoriasis treated with biologic agents was found (RR, 0.97; 95% CI, 0.85-1.10). Psoriatic arthritis was not associated with increased risk of cancer overall (RR, 1.02; 95% CI, 0.97-1.08).
CONCLUSIONS AND RELEVANCE
Patients with psoriasis appear to have a slightly increased risk of cancer, particularly keratinocyte cancer and lymphomas. Data on treatment with biologic agents did not show an increased risk of cancer. Data on cancer in patients with psoriatic arthritis remain scarce, and further research is warranted in this area.

Meta-Analysis
BACKGROUND
Urinary incontinence is a common condition in the general population and, in particular, the older adults population, which reduces the quality of life of these people, so this study aims to systematically examine and meta-analyse the overall prevalence of urinary incontinence in older women around the world and the related and influential factors.
METHODS
This report is a comprehensive systematic review and meta-analysis of the findings of research on urinary incontinence in older adults people across the world through looking for MEDLINE, Cochrane Library Sciencedirect, Embase, Scopus, ProQuest and Persian databases, namely iranmedex, magiran, and SID from January 2000 to April 2020, the heterogeneity of the experiments was measured using the I index and the data processing was done in the Systematic Meta-Analysis programme.
RESULTS
In 29 studies and the sample size of 518,465 people in the age range of 55-106 years, urinary incontinence in older adults' women in the world based on a meta-analysis of 37.1% (95% CI: 29.6-45.4%) was obtained. The highest prevalence of urinary incontinence was reported in older adults' women in Asia with 45.1% (95% CI: 36.9-53.5%). Meta-regression also showed that with increasing the sample size and year of the study, the overall prevalence of urinary incontinence in the older adults women of the world decreased and increased, respectively, which were statistically significant differences (P < 0.05). According to studies, the most important factors influencing the incidence of urinary incontinence in older women are women's age (p < 0.001), obesity (p < 0.001), diabetes (p < 0.001), women's education (p < 0.001), delivery rank (p < 0.001), hypertension (p < 0.001), smoking (p < 0.001). They also have urinary tract infections (p < 0.001).
CONCLUSION
Given the high prevalence of urinary incontinence in older women around the world, health policy makers must consider control and diagnostic measures in older women and prioritize treatment and rehabilitation activities.

Review
While the epidemiology of adult heart failure has been extensively researched, this systematic review addresses the less well characterized incidence and prevalence of pediatric HF. The search strategy used Cochrane methodology and identified 83 unique studies for inclusion. Studies were categorized according to whether the HF diagnosis was reported as primary (n = 10); associated with other cardiovascular diseases (CVDs) (n = 49); or associated with non-CVDs (n = 24). A narrative synthesis of the evidence is presented. For primary HF, the incidence ranged from 0.87/100,000 (UK and Ireland) to 7.4/100,000 (Taiwan). A prevalence of 83.3/100,000 was reported in one large population-based study from Spain. HF etiology varied across regions with lower respiratory tract infections and severe anemia predominating in lower income countries, and cardiomyopathies and congenital heart disease major causes in higher income countries. Key findings for the other categories included a prevalence of HF associated with cardiomyopathies ranging from 36.1% (Japan) to 79% (US); associated with congenital heart disease from 8% (Norway) to 82.2% (Nigeria); associated with rheumatic heart diseases from 1.5% (Turkey) to 74% (Zimbabwe); associated with renal disorders from 3.8% (India) to 24.1% (Nigeria); and associated with HIV from 1% (US) to 29.3% (Brazil). To our knowledge, this is the first systematic review of the topic and strengthens current knowledge of pediatric HF epidemiology. Although a large body of research was identified, heterogeneity in study design and diagnostic criteria limited the ability to compare regional data. Standardized definitions of pediatric HF are required to facilitate cross-regional comparisons of epidemiological data.

Review
Experiencing homelessness is associated with poor health, high levels of chronic disease and high premature mortality. Experiencing homelessness is known to be socially stigmatised and stigma has been suggested as a cause of health inequalities. No previous review has synthesised the evidence about stigma related to homelessness and the impact on the health of people experiencing homelessness. The present mixed-methods review systematically searched four databases and retrieved 21 original articles with relevant data around stigma, homelessness and health. Across all studies, there was broad agreement that some people experiencing homelessness experience significant stigma from providers when accessing health care and this impacts on general health and service access. There is also evidence that perceived stigma related to homelessness correlates with poorer mental and physical health.

Meta-Analysis Review
INTRODUCTION AND HYPOTHESIS
Urinary incontinence (UI) is a common and embarrassing complaint for pregnant women. Reported prevalence and incidence figures show a large range, due to varying case definitions, recruited population and study methodology. Precise prevalence and incidence figures on (bothersome) UI are of relevance for health care providers, policy makers and researchers. Therefore, we conducted a systematic review and meta-analysis to investigate the prevalence and incidence of UI in pregnancy in the general population for relevant subgroups and assessed experienced bother.
METHODS
All observational studies published between January 1998 and October 2018 reporting on prevalence and/or incidence of UI during pregnancy were included. All women, regardless of weeks of gestation and type of UI presented in all settings, were of interest. A random-effects model was used. Subgroup analyses were conducted by parity, trimester and subtype of UI.
RESULTS
The mean (weighted) prevalence based on 44 included studies, containing a total of 88.305 women, was 41.0% (range of 9-75%). Stress urinary incontinence (63%) is the most prevalent type of UI; 26% of the women reported daily loss, whereas 40% reported loss on a monthly basis. Bother was experienced as mild to moderate.
CONCLUSIONS
UI is very prevalent and rising with the weeks of gestation in pregnancy. SUI is the most common type and in most cases it was a small amount. Bother for UI is heterogeneously assessed and experienced as mild to moderate by pregnant women.

Meta-Analysis
BACKGROUND
Adult attention-deficit hyperactivity disorder (ADHD) has recently attracted much attention, however, an up-to-date estimation on the prevalence of adult ADHD is lacking. In this study, we aimed to assess the global prevalence of adult ADHD in the general population through a systematic review and meta-analysis.
METHODS
PubMed, Medline, Embase and PsycINFO were searched to identify relevant articles published from January 2000 onwards. Population-based studies that were conducted in the general adult population and quantified the prevalence of adult ADHD were included.
RESULTS
The prevalence of persistent adult ADHD (with a childhood onset) and symptomatic adult ADHD (regardless of a childhood onset) both decreased with advancing age. By adjusting for the global demographic structure in 2020, the prevalence of persistent adult ADHD was 2.58% and that of symptomatic adult ADHD was 6.76%, translating to 139.84 million and 366.33 million affected adults in 2020 globally.
CONCLUSIONS
This study provides an up-to-date estimation of the global prevalence of both persistent and symptomatic adult ADHD. A well-defined strategy for diagnosing adult ADHD and large-scale investigations on the epidemiology of adult ADHD are needed.

Meta-Analysis
Problems with sleep are reported to be common after stroke but the incidence and prevalence of insomnia and insomnia symptoms following stroke is not yet established. The aim of this review was to conduct a systematic review and meta-analysis of the incidence and prevalence of insomnia and insomnia symptoms in individuals affected by stroke. We searched seven main electronic databases to identify studies until September 25, 2018. No studies examining incidence of post-stroke insomnia were identified. Twenty-two studies on prevalence of insomnia or insomnia symptoms including individuals with stroke were included with fourteen studies suitable for inclusion in the meta-analysis. Meta-analysis indicated pooled prevalence of 38.2% (CI 30.1-46.5) with significantly higher prevalence estimates for studies using non-diagnostic tools, 40.70% (CI 30.96-50.82) compared to studies using diagnostic assessment tools 32.21% (CI 18.5-47.64). Greater insomnia symptoms were indicated in those with comorbid depression and anxiety. The prevalence of both insomnia and insomnia symptoms are considerably higher in stroke survivors compared to the general population. Studies investigating the incidence, insomnia symptom profile and changes in insomnia prevalence over time are needed to inform clinical practice and to encourage tailored interventions that consider this symptomatology. PROSPERO registration number CRD42017065670.

Meta-Analysis Review
BACKGROUND
Stroke is the second cause of death and the first cause of disability in Europe. The number of stroke patients shows a rapidly increasing due to the increase in the elderly population. The aim of this meta-analysis is to evaluate the prevalence and incidence of stroke in Europe.
METHOD
We conducted a literature search in MEDLINE, SCOPUS, CINAHL Complete and EMBASE, using the keywords "stroke", "cerebrovascular accident", "epidemiology", "prevalence", "incidence" and "Europe". In order to evaluate the quality and risk of bias, we used the Hoy's modified scale for prevalence studies and the Newcastle Ottawa Scale for incidence studies. A random effects model with 95% confidence intervals (95%CI) was used for the meta-analysis. The I2 statistic was applied to assess heterogeneity.
RESULTS
The prevalence of stroke in Europe adjusted for sex was estimated at 9.2% (95%CI: 4.4-14.0). The prevalence was 9.1% (95%CI: 4.7-13.6) in men and 9.2% (95%CI: 4.1-14.4) in women, and increased with age. The incidence of stroke in Europe adjusted for sex was 191.9 per 100,000 person-years (95%CI: 156.4-227.3); it was 195.7 per 100,000 person-years (95%CI: 142.4-249.0) in men and 188.1 per 100,000 person-years (95%CI: 138.6-237.7) in women. Again, these rates increased with age.
CONCLUSION
The prevalence of stroke in Europe is 9.2%. The incidence of stroke in Europe is 191.9 per 100,000 person-years. The prevalence of stroke has increased, whereas the incidence of stroke is stable in comparison with studies conducted at the beginning of the 21st century.

Meta-Analysis Review
Morbidity and mortality in homeless individuals, prisoners, sex workers, and individuals with substance use disorders in high-income countries: a systematic review and meta-analysis.
BACKGROUND
Inclusion health focuses on people in extremely poor health due to poverty, marginalisation, and multimorbidity. We aimed to review morbidity and mortality data on four overlapping populations who experience considerable social exclusion: homeless populations, individuals with substance use disorders, sex workers, and imprisoned individuals.
METHODS
For this systematic review and meta-analysis, we searched MEDLINE, Embase, and the Cochrane Library for studies published between Jan 1, 2005, and Oct 1, 2015. We included only systematic reviews, meta-analyses, interventional studies, and observational studies that had morbidity and mortality outcomes, were published in English, from high-income countries, and were done in populations with a history of homelessness, imprisonment, sex work, or substance use disorder (excluding cannabis and alcohol use). Studies with only perinatal outcomes and studies of individuals with a specific health condition or those recruited from intensive care or high dependency hospital units were excluded. We screened studies using systematic review software and extracted data from published reports. Primary outcomes were measures of morbidity (prevalence or incidence) and mortality (standardised mortality ratios [SMRs] and mortality rates). Summary estimates were calculated using a random effects model.
FINDINGS
Our search identified 7946 articles, of which 337 studies were included for analysis. All-cause standardised mortality ratios were significantly increased in 91 (99%) of 92 extracted datapoints and were 11·86 (95% CI 10·42-13·30; I=94·1%) in female individuals and 7·88 (7·03-8·74; I=99·1%) in men. Summary SMR estimates for the International Classification of Diseases disease categories with two or more included datapoints were highest for deaths due to injury, poisoning, and other external causes, in both men (7·89; 95% CI 6·40-9·37; I=98·1%) and women (18·72; 13·73-23·71; I=91·5%). Disease prevalence was consistently raised across the following categories: infections (eg, highest reported was 90% for hepatitis C, 67 [65%] of 103 individuals for hepatitis B, and 133 [51%] of 263 individuals for latent tuberculosis infection), mental health (eg, highest reported was 9 [4%] of 227 individuals for schizophrenia), cardiovascular conditions (eg, highest reported was 32 [13%] of 247 individuals for coronary heart disease), and respiratory conditions (eg, highest reported was 9 [26%] of 35 individuals for asthma).
INTERPRETATION
Our study shows that homeless populations, individuals with substance use disorders, sex workers, and imprisoned individuals experience extreme health inequities across a wide range of health conditions, with the relative effect of exclusion being greater in female individuals than male individuals. The high heterogeneity between studies should be explored further using improved data collection in population subgroups. The extreme health inequity identified demands intensive cross-sectoral policy and service action to prevent exclusion and improve health outcomes in individuals who are already marginalised.
