Meta-Analysis Review
This review aims to examine the prevalence and incidence of postpartum depression among healthy mothers without prior history of depression including postpartum depression and who gave birth to healthy full-term infants. A systematic search of ClinicalTrials.gov, CINAHL, EMBASE, PsycINFO, and PubMed was performed for English articles from the inception of the database to November 2017, as well as a manual search of the reference lists of the included articles, and an expert panel was consulted. Across 15,895 articles, 58 articles (N = 37,294 women) were included in the review. The incidence of postpartum depression was 12% [95% CI 0.04-0.20] while the overall prevalence of depression was 17% [95% CI 0.15-0.20] among healthy mothers without a prior history of depression. Prevalence was similar regardless of the type of diagnostic tool used; however, there were statistical differences in the prevalence between different geographical regions, with the Middle-East having the highest prevalence (26%, 95% CI 0.13-0.39) and Europe having the lowest (8%, 95% CI 0.05-0.11). There was no statistical difference in prevalence between different screening time points, but an increasing prevalence was observed beyond six months postpartum. Intervention studies often neglect healthy mothers. This review reports a similar prevalence rate of postpartum depression among mothers without history of depression when compared to mothers with history of depression. Thus, future studies should place equal emphasis on this neglected group of mothers so that targeted interventions and follow-ups can be introduced at appropriate time points.

Meta-Analysis Review
BACKGROUND
Pressure injuries are a fundamental safety concern in older people living in nursing homes. Recent studies report a disparate body of evidence on pressure injury prevalence and incidence in this population.
OBJECTIVES
To systematically quantify the prevalence and incidence of pressure injuries among older people living in nursing homes, and to identify the most frequently occurring PI stage(s) and anatomical location(s).
DESIGN
Systematic review and meta-analysis.
SETTING(S)
Nursing homes, aged care, or long-term care facilities.
PARTICIPANTS
Older people, 60 years and older.
METHODS
Cross-sectional and cohort studies reporting on either prevalence or incidence of pressure injuries were included. Studies published in English from 2000 onwards were systematically searched in Medline, PubMed, Embase, Cochrane Library, CINAHL and ProQuest. Screening, data extraction and quality appraisal were undertaken independently by two or more authors and adjudicated by another. Outcomes included pressure injury point prevalence, cumulative incidence, and nursing home acquired pressure injury rate. In meta-analyses, Cochrane's Q test and the I statistic were used to explore heterogeneity. Random effects models were used in the presence of substantial heterogeneity. Sources of heterogeneity were investigated by subgroup analyses and meta-regression.
RESULTS
3384 abstracts were screened, and 47 full-text studies included. In 30 studies with 355,784 older people, the pooled pressure injury prevalence for any stage was 11.6 % (95 % CI 9.6-13.7 %). Fifteen studies with 5,421,798 older people reported the prevalence of pressure injury excluding stage I and the pooled estimate was 7.2 % (95 % CI 6.2-8.3 %). The pooled incidence for pressure injury of any stage in four studies with 10,645 older people was 14.3 % (95 % CI 5.5-26.2 %). Nursing home acquired pressure injury rate was reported in six studies with 79,998 older people and the pooled estimate was 8.5 % (95 % CI 4.4-13.5 %). Stage I and stage II pressure injuries were the most common stages reported. The heel (34.1 %), sacrum (27.2 %) and foot (18.4 %) were the three most reported locations of pressure injuries. Meta-regression results indicated a reduction in pressure injury prevalence over the years of data collection.
CONCLUSION
The burden of pressure injuries among older people in nursing homes is similar to hospitalised patients and requires a targeted approach to prevention as is undertaken in hospitals. Future studies using robust methodologies focusing on epidemiology of pressure injury development in older people are needed to conduct as the first step of preventing pressure injuries.

BACKGROUND
The burden of stroke is increasing in India; stroke is now the fourth leading cause of death and the fifth leading cause of disability. Previous research suggests that the incidence of stroke in India ranges between 105 and 152/100,000 people per year. However, there is a paucity of available data and a lack of uniform methods across published studies.
AIM
To identify high-quality prospective studies reporting the epidemiology of stroke in India.
SUMMARY OF REVIEW
A search strategy was modified from the Cochrane Stroke Strategy and adapted for a range of bibliographic databases from January 1997 to August 2020. From 7717 identified records, nine studies were selected for inclusion; three population-based registries, a further three population-based registries also using community-based ascertainment and three community-based door-to-door surveys. Studies represented the four cities of Mumbai, Trivandrum, Ludhiana, Kolkata, the state of Punjab, and 12 villages of Baruipur in the state of West Bengal. The total population denominator was 22,479,509 and 11,654 (mean 1294 SD 1710) people were identified with incident stroke. Crude incidence of stroke ranged from 108 to 172/100,000 people per year, crude prevalence from 26 to 757/100,000 people per year, and one-month case fatality rates from 18% to 42%.
CONCLUSIONS
Further high-quality evidence is needed across India to guide stroke policy and inform the development and organization of stroke services. Future researchers should consider the World Health Organization STEPwise approach to Surveillance framework, including longitudinal data collection, the inclusion of census population data, and a combination of hospital-registry and comprehensive community ascertainment strategies to ensure complete stroke identification.

Meta-Analysis
OBJECTIVE
To review observational studies reporting medical device-related pressure injuries and to identify the medical devices commonly associated with pressure injuries.
DESIGN
A systematic review of primary research was undertaken, according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines.
DATA SOURCES
A comprehensive electronic literature search of AMED, CINAHL, MEDLINE, PsycINFO, Web of Science, British Nursing Database and Google Scholar was conducted from inception to 31 December 2018. Studies that reported the prevalence or incidence of medical device-related pressure injuries and published in English language were included in the review.
REVIEW METHODS
The eligibility of studies was evaluated independently by three of the four authors and audited by an independent researcher. The titles and abstracts of all studies were screened to identify studies that met the inclusion criteria. Full-text articles of the remaining studies were obtained and screened against the inclusion criteria. Risk of bias was assessed using the Newcastle-Ottawa scale. Meta-analysis was conducted using the 'metaprop' routine, with estimates of medical device-related pressure injuries from the included studies pooled using DerSimonian-Laird random-effects model. Meta-regression analysis was also conducted to examine between-study heterogeneity.
RESULTS
Twenty-nine studies (17 cross-sectional studies; 12 cohort studies) comprising data on 126,150 patients were eligible for inclusion in this review. The mean ages for patients were approximately 36.2 years (adults) and 5.9 years (children). The estimated pooled incidence and prevalence of medical device-related pressure injuries were 12% (95% CI 8-18) and 10% (95% CI 6-16) respectively. These results should be interpreted with caution given the high levels of heterogeneity observed between included studies. The commonly identified medical devices associated with the risk of developing medical device-related pressure injuries include respiratory devices, cervical collars, tubing devices, splints, and intravenous catheters.
CONCLUSIONS
Medical device-related pressure injuries are among key indicators of patient safety and nursing quality in healthcare facilities. This systematic review and meta-analysis provide up-to-date estimates of the extent and nature of medical device-related pressure injuries, and the findings suggest that device-related pressure injuries are a public health issue of significance, especially as these injuries affect patients' wellbeing and increase the cost of care for both patients and providers. Further research is required to inform strategies for increasing the reporting and risk assessment of medical device-related pressure injuries.

Meta-Analysis
BACKGROUND AND AIMS
Owing to 2018 expanded diagnostic criteria for eosinophilic esophagitis (EoE) and thus a possible increase in diagnosis, previous studies on the global incidence and prevalence of EoE may need to be updated. We aimed to describe global, regional, and national trends in the incidence and prevalence of EoE from 1976 to 2022 and analyze their associations with geographic, demographic, and social factors through a systematic review.
METHODS
We searched the PubMed/MEDLINE, Embase, CINAHL, Google Scholar, and Cochrane databases from their inception dates to December 20, 2022, for studies that reported the incidence or prevalence of EoE in the general population. We calculated the global incidence and prevalence of EoE using pooled estimates with 95% confidence intervals (CIs) and performed subgroup analysis based on age, sex, race, geographical area, World Bank income group, and diagnostic criteria of EoE.
RESULTS
Forty studies met the eligibility criteria, including over 288 million participants and 147,668 patients with EoE from 15 countries across the five continents. The global pooled incidence and prevalence of EoE were 5.31 cases per 100,000 inhabitant-years (95% CI, 3.98-6.63; number of studies, 27; sample population, 42,191,506) and 40.04 cases per 100,000 inhabitant-years (95% CI, 31.10-48.98; number of studies, 20; sample population, 30,467,177), respectively. The pooled incidence of EoE was higher in high-income countries (vs low- or middle-income countries), males, and North America (vs Europe and Asia). The global prevalence of EoE followed a similar pattern. The pooled prevalence of EoE gradually increased from 1976 to 2022 (1976-2001; 8.18; 95% CI, 3.67-12.69 vs 2017-2022; 74.42; 95% CI, 39.66-109.19 cases per 100,000 inhabitant-years).
CONCLUSIONS
The incidence and prevalence of EoE have increased substantially and vary widely across the world. Further research is needed to evaluate the incidence and prevalence of EoE in Asia, South America, and Africa.

Meta-Analysis
OBJECTIVE
The definition of drug-resistant epilepsy (DRE) affects case identification and treatment, and impacts prevalence or incidence estimates and health burden estimation in epidemiology. The objective of this systematic review is to evaluate the consistency between definitions of DRE in the literature and the official definition in the International League Against Epilepsy (ILAE) guidelines, and to estimate the incidence, prevalence, and risk factors for DRE.
METHODS
MEDLINE and EMBASE were searched for observational studies of DRE published between January 1980 and July 2015. The definitions of DRE in these studies were compared with the definition in the ILAE guidelines. Random-effect model meta-analyses were used to generate pooled estimates of prevalence or incidence and pooled odds ratios of the association with risk factors.
RESULTS
Thirty-five studies met inclusion criteria, including 13 080 epilepsy patients and 3941 patients with DRE. The definition of DRE varied widely across studies, with only 12% meeting the requirements of the ILAE definition. The pooled prevalence proportion of DRE among epilepsy patients was 0.30 (95% confidence interval [CI] 0.19-0.42), and the pooled incidence proportion was 0.15 (95% CI 0.11-0.19). Age at onset, symptomatic epilepsy, abnormal neuroimaging findings, abnormal electroencephalography results, history of mental retardation, neuropsychiatric disorders, febrile seizure, and status epilepticus increased risk for DRE.
SIGNIFICANCE
There are limited high-quality data available on DRE. Lack of consistency in definitions limits the ability to obtain robust estimates on the burden of DRE. More data based on the ILAE definition from well-designed epidemiologic studies are needed to generate accurate and reliable results.

Meta-Analysis Review
OBJECTIVE
Epidemiological studies of primary Sjögren's syndrome (pSS) are crucial for describing the burden to society and the public medical system and for shedding light on aetiology. Previous reports of the epidemiology of pSS show variable outcomes. We conducted a systematic review of the epidemiology of pSS to assess the prevalence rates (PRs) and incidence rates (IRs), and to investigate possible geographic variations in pSS.
METHODS
A systematic literature search of PubMed and Embase (updated to 22 October 2013) was performed to identify all published reports on the epidemiology of pSS. The incidence and prevalence rates of pSS were summarised with IRs or PRs and 95% CIs.
RESULTS
The literature search yielded 1880 related citations. Only 21 fulfilled the inclusion criteria. According to a random-effects model, the pooled IR for pSS was 6.92 (95% CI 4.98 to 8.86) per 100 000 person-years. The overall PR was 60.82 (95% CI 43.69 to 77.94) cases per 100 000 inhabitants with a slightly lower estimate of Baodong Qin is BDQ, Jiaqi Wang is JQW, Zaixing Yang is ZXY, Renqian Zhong is RQZ. 43.03 (25.74 to 60.31) cases per 100 000 inhabitants when only considering population-based studies. The female/male ratio in incidence data was 9.15 (95% CI 3.35 to 13.18). The female/male ratio in prevalence data was 10.72 (95% CI 7.35 to 15.62). The overall age of pSS patients was 56.16 years (95% CI 52.54 to 59.78).
CONCLUSIONS
Incidence and prevalence rates of pSS vary widely around the world. The results help us better understand the global epidemiology of pSS. Large population-based studies combining meticulous case-finding and case-ascertainment strategies are needed.

Meta-Analysis
The purpose of this systematic review and meta-analysis was to assess the prevalence, incidence and risk factors of peri-implantitis in the current literature. An electronic search was performed to identify publications from January 1980 until March 2016 on 9 databases. The prevalence and incidence of peri-implantitis were assessed in different subgroups of patients and the prevalences were adjusted for sample size (SSA) of studies. For 12 of 111 identified putative risk factors and risk indicators, forest plots were created. Heterogeneity analysis and random effect meta-analysis were performed for selected potential risk factors of peri-implantitis. The search retrieved 8357 potentially relevant studies. Fifty-seven studies were included in the systematic review. Overall, the prevalence of peri-implantitis on implant level ranged from 1.1% to 85.0% and the incidence from 0.4% within 3 years, to 43.9% within 5 years, respectively. The median prevalence of peri-implantitis was 9.0% (SSA 10.9%) for regular participants of a prophylaxis program, 18.8% (SSA 8.8%) for patients without regular preventive maintenance, 11.0% (SSA 7.4%) for non-smokers, 7.0% (SSA 7.0%) among patients representing the general population, 9.6% (SSA 9.6%) for patients provided with fixed partial dentures, 14.3% (SSA 9.8%) for subjects with a history of periodontitis, 26.0% (SSA 28.8%) for patients with implant function time ≥5 years and 21.2% (SSA 38.4%) for ≥10 years. On a medium and medium-high level of evidence, smoking (effect summary OR 1.7, 95% CI 1.25-2.3), diabetes mellitus (effect summary OR 2.5; 95% CI 1.4-4.5), lack of prophylaxis and history or presence of periodontitis were identified as risk factors of peri-implantitis. There is medium-high evidence that patient's age (effect summary OR 1.0, 95% CI 0.87-1.16), gender and maxillary implants are not related to peri-implantitis. Currently, there is no convincing or low evidence available that identifies osteoporosis, absence of keratinized mucosa, implant surface characteristics or edentulism as risk factors for peri-implantitis. Based on the data analyzed in this systematic review, insufficient high-quality evidence is available to the research question. Future studies of prospective, randomized and controlled type including sufficient sample sizes are needed. The application of consistent diagnostic criteria (eg, according to the latest definition by the European Workshop on Periodontology) is particularly important. Very few studies evaluated the incidence of peri-implantitis; however, this study design may contribute to examine further the potential risk factors.

BACKGROUND
Global child mortality reduced substantially during the Millennium Development Goal period (2000-15). We aimed to estimate morbidity, mortality, and prevalence of risk factors for child pneumonia at the global, regional, and national level for developing countries for the Millennium Development Goal period.
METHODS
We estimated the incidence, number of hospital admissions, and in-hospital mortality due to all-cause clinical pneumonia in children younger than 5 years in developing countries at 5-year intervals during the Millennium Development Goal period (2000-15) using data from a systematic review and Poisson regression. We estimated the incidence and number of cases of clinical pneumonia, and the pneumonia burden attributable to HIV for 132 developing countries using a risk-factor-based model that used Demographic and Health Survey data on prevalence of the various risk factors for child pneumonia. We also estimated pneumonia mortality in young children using data from multicause models based on vital registration and verbal autopsy.
FINDINGS
Globally, the number of episodes of clinical pneumonia in young children decreased by 22% from 178 million (95% uncertainty interval [UI] 110-289) in 2000 to 138 million (86-226) in 2015. In 2015, India, Nigeria, Indonesia, Pakistan, and China contributed to more than 54% of all global pneumonia cases, with 32% of the global burden from India alone. Between 2000 and 2015, the burden of clinical pneumonia attributable to HIV decreased by 45%. Between 2000 and 2015, global hospital admissions for child pneumonia increased by 2·9 times with a more rapid increase observed in the WHO South-East Asia Region than the African Region. Pneumonia deaths in this age group decreased from 1·7 million (95% UI 1·7-2·0) in 2000 to 0·9 million (0·8-1·1) in 2015. In 2015, 49% of global pneumonia deaths occurred in India, Nigeria, Pakistan, Democratic Republic of the Congo, and Ethiopia collectively. All key risk factors for child pneumonia (non-exclusive breastfeeding, crowding, malnutrition, indoor air pollution, incomplete immunisation, and paediatric HIV), with the exception of low birthweight, decreased across all regions between 2000 and 2015.
INTERPRETATION
Globally, the incidence of child pneumonia decreased by 30% and mortality decreased by 51% during the Millennium Development Goal period. These reductions are consistent with the decrease in the prevalence of some of the key risk factors for pneumonia, increasing socioeconomic development and preventive interventions, improved access to care, and quality of care in hospitals. However, intersectoral action is required to improve socioeconomic conditions and increase coverage of interventions targeting risk factors for child pneumonia to accelerate decline in pneumonia mortality and achieve the Sustainable Development Goals for health by 2030.

Meta-Analysis
In 1999, the World Health Organization (WHO) estimated that one-third of the world's population had latent tuberculosis infection (LTBI), which was recently updated to one-fourth. However, this is still based on controversial assumptions in combination with tuberculin skin test (TST) surveys. Interferon-γ release assays (IGRAs) with a higher specificity than TST have since been widely implemented, but never used to estimate the global LTBI prevalence.We conducted a systematic review and meta-analysis of LTBI estimates based on both IGRA and TST results published between 2005 and 2018. Regional and global estimates of LTBI prevalence were calculated. Stratification was performed for low, intermediate and high TB incidence countries and a pooled estimate for each area was calculated using a random effects model.Among 3280 studies screened, we included 88 studies from 36 countries with 41 IGRA (n=67 167) and 67 TST estimates (n=284 644). The global prevalence of LTBI was 24.8% (95% CI 19.7-30.0%) and 21.2% (95% CI 17.9-24.4%), based on IGRA and a 10-mm TST cut-off, respectively. The prevalence estimates correlated well to WHO incidence rates (Rs=0.70, p<0.001).In the first study of the global prevalence of LTBI derived from both IGRA and TST surveys, we found that one-fourth of the world's population is infected. This is of relevance, as both tests, although imperfect, are used to identify individuals eligible for preventive therapy. Enhanced efforts are needed targeting the large pool of latently infected individuals, as this constitutes an enormous source of potential active tuberculosis.
