Meta-Analysis
BACKGROUND
Helicobacter pylori is a gastrointestinal pathogen that infects around half of the world's population. H. pylori infection is the most severe known risk factor for gastric cancer (GC), which is the second highest cause of cancer-related deaths globally. We conducted a systematic review and meta-analysis to assess the global prevalence of GC in H. pylori-infected individuals.
METHODS
We performed a systematic search of the PubMed, Web of Science, and Embase databases for studies of the prevalence of GC in H. pylori-infected individuals published from 1 January 2011 to 20 April 2021. Metaprop package were used to calculate the pooled prevalence with 95% confidence interval. Random-effects model was applied to estimate the pooled prevalence. We also quantified it with the I index. Based on the Higgins classification approach, I values above 0.7 were determined as high heterogeneity.
RESULTS
Among 17,438 reports screened, we assessed 1053 full-text articles for eligibility; 149 were included in the final analysis, comprising data from 32 countries. The highest and lowest prevalence was observed in America (pooled prevalence: 18.06%; 95% CI: 16.48 - 19.63; I: 98.84%) and Africa (pooled prevalence: 9.52%; 95% CI: 5.92 - 13.12; I: 88.39%). Among individual countries, Japan had the highest pooled prevalence of GC in H. pylori positive patients (Prevalence: 90.90%:95% CI: 83.61-95.14), whereas Sweden had the lowest prevalence (Prevalence: 0.07%; 95% CI: 0.06-0.09). The highest and lowest prevalence was observed in prospective case series (pooled prevalence: 23.13%; 95% CI: 20.41 - 25.85; I2: 97.70%) and retrospective cohort (pooled prevalence: 1.17%; 95% CI: 0.55 - 1.78; I 2: 0.10%).
CONCLUSIONS
H. pylori infection in GC patients varied between regions in this systematic review and meta-analysis. We observed that large amounts of GCs in developed countries are associated with H. pylori. Using these data, regional initiatives can be taken to prevent and eradicate H. pylori worldwide, thus reducing its complications.

Meta-Analysis
BACKGROUND
Gastric cancer is the fifth most common cancer globally, with about 75% of cases occurring in Asia. While chronic atrophic gastritis (CAG) and intestinal metaplasia (IM) are well-recognized preneoplastic gastric lesions, we determined the prevalence and temporal trend of CAG and IM in Asia over the past 50 years.
METHODS
In this systematic review and meta-analysis, we searched PubMed, Embase, MEDLINE, Scopus, and Web of Science for studies reporting the prevalence of CAG and IM in Asia (according to the United Nations geoscheme) published between 1970 and 2022. Heterogeneity was assessed by the I index and Cochran Q test. We adopted the random effects model to estimate the pooled prevalence and 95% confidence interval (CI). The slope of prevalence was estimated as a function of time in simple linear regression and weighted meta-regression models to demonstrate the temporal trend. Studies that reported the odds ratio (OR) of Helicobacter pylori infection and CAG/IM were analyzed separately to compile a pooled OR with a 95% CI. This study was registered in INPLASY2022120028.
RESULTS
Of the 81 studies from 19 Asian countries identified, the pooled prevalence for CAG and IM in Asia was 26.1% (95%CI: 22.7-30.0) and 22.9% (95%CI: 19.7-26.6), respectively. Over the past 5 decades, there was a significant decline in the prevalence of IM (slope in adjusted meta-regression models: -0.79 [95%CI: -1.28 to -0.26], P = 0.003), but there was no significant change in the pooled prevalence of CAG. Within Asia, the prevalence varied significantly among different regions. Southern Asia reported the highest pooled prevalence of CAG (42.9%, 95%CI: 27.5%-67.1%), while Western Asia reported the lowest level (12.7%, 95%CI: 5.0%-32.3%). For IM, Eastern Asia reported the highest prevalence (27.1%, 95%CI: 21.1-34.9), with the lowest prevalence reported in Western Asia (3.1%; 95% CI 1.2%-8.0%). H. pylori infection was linked to CAG and IM with OR of 2.16 (95%CI: 2.09-2.22) and 1.64 (95%CI: 1.57-1.72), respectively.
CONCLUSION
This updated meta-analysis showed that up to 26% of study individuals in Asia harbored preneoplastic gastric lesions. There was a declining temporal trend in the prevalence of IM, but not for CAG, in Asia.

Review
BACKGROUND
Homeless people present high rates of psychopathology, including personality disorders. Given the link between personality disorders and attachment, and the potential importance of these two traits for understanding homeless populations.
AIMS
Our aim was to review all studies focusing on attachment and on the full assessment of personality disorders in the homeless.
METHOD
Overall, 213 studies were screened through title and abstract. Of these, 63 articles were chosen for full-text assessment.
RESULTS
A total of 14 articles met eligibility criteria and were included in the present review. Six studies evaluated personality disorders and eight studies assessed attachment in the homeless. In general, reports suggested that personality disorders are highly common in the homeless, with frequencies ranging between 64% and 79% for any personality disorder. The most common personality diagnoses were paranoid (14%-74%), borderline (6%-62%), avoidant (14%-63%), and antisocial (4%-57%) personality disorders. Attachment reports differed in the methods used and presented diverse results and correlates. Even so, insecure types of attachment dominated in the homeless, accounting for 62% to 100% of the samples.
CONCLUSIONS
The high prevalence of personality disorders and insecure types of attachment in the homeless may impact intervention strategies for these people. The available literature evaluating attachment and the full assessment of personality disorders in the homeless is scarce, which supports the need for more research on these two topics.

AIM
Molar incisor hypomeralisation (MIH) is a dental condition clinically characterised by the presence of morphological and qualitative enamel defects involving the occlusal and/or incisal third of one or more permanent molars or incisors. Its worldwide prevalence ranges between 2.4 and 40%. Several harmful conditions, such as genetic or medical problems during pregnancy, may act together and increase the risk of MIH. The main objective of this systematic review is to assess whether there is a correlation between MIH and dental caries in mixed or permanent dentition.
METHODS
An electronic search was performed on PubMed (Medline), Scopus and Cochrane Library for articles published from August 2022 to April 2023. Cohort, cross-sectional, retrospective and prospective studies were included. In vitro and animal studies, as well as clinical cases and systematic reviews, were excluded. Studies not differentiating between mixed and permanent dentition were excluded. The observed variables were DMFT (Decayed Missed Filled Teeth) score, DMFS (Decayed Missed Filled Surface) and DMF scores related to FPM (First Permanent Molar) and the clinical prevalence of MIH.
CONCLUSION
DMFT, DMFS and DMFT on FPM scores are significantly different between the group of patients with MIH and the control group. The available evidence supports a correlation between MIH lesions and caries. Caries indexes scores increase proportionally to the severity of MIH.

Review
OBJECTIVE
The world population gradually getting older, age-related sarcopenia is becoming more frequent. Known to be highly prevalent in high income countries, relative data in Africa are still scarce. This review aims to estimate the prevalence of sarcopenia in Africa and its characteristics.
STUDY DESIGN AND SETTING
A literature search in PubMed, Web of Science, Google Scholar, and Scopus was conducted in October 2022. All studies reporting the prevalence of sarcopenia in Africa within 15 years were included, and we did an assessment of bias with Hoy et al's risk bias assessment tool. The estimated prevalence of sarcopenia was the outcome and we performed secondary analyses by age, gender, and diagnostic criteria. The random effect model was used for the prevalence estimation. The prevalence of sarcopenia and 95% confidence interval (95% CI) were calculated using the inverse-variance method.
RESULTS
A total of 17 studies met our eligibility criteria, for a study population of 12,690 participants with 44.3% males and 55.7% females. The overall prevalence of sarcopenia was 25% (95% CI: 19-30%). The prevalence of sarcopenia among 50 years old and older was 23% (95% CI: 17-29%). We had a higher prevalence of sarcopenia among males (30%, %95 IC: 20-39%) than females (29%, %95 IC: 21-36%). The prevalence of sarcopenia was different depending on the diagnosis criteria used.
CONCLUSION
The prevalence of sarcopenia in Africa was relatively high. However, the fact that the majority of included studies were hospital-based studies shows the necessity of further community-based studies in order to have a more accurate representation of the situation in the general population.

Meta-Analysis
BACKGROUND
Several studies have reported large increases in the incidence of eosinophilic oesophagitis (EoE) in the last 20 years. We aimed to systematically review the incidence and prevalence of EoE, focused on all European countries.
METHODS
Systematic review and meta-analysis up to 31 December 2022, based on PubMed, CINAHL and extensive hand searching of reference lists. Twenty-five eligible studies were identified and included.
RESULTS
For both adults and children, the highest EoE incidence and prevalence have been reported from regional studies in Spain. EoE incidence for both adults and children was significantly lower (p < 0.001) in nationwide studies (meta-analysis = 3.64 per 100,000 person-years overall) compared with regional or centre-based studies (7.16). EoE incidence and prevalence were significantly higher (p < 0.001) in adults than children. All studies that reported on longitudinal trends in EoE incidence showed increases over time, more markedly during more recent years. Larger increases in incidence tend to refer to regional rather than nationwide studies; from Spain, Switzerland and Denmark, both for paediatric and adult age groups. Increases in EoE incidence 100,000 person-years were larger than for incidence per number of diagnostic endoscopies. The most frequently reported co-morbidities in adults were rhinitis, followed by asthma, food allergy and gastroesophageal reflux disease, and in children, erosive oesophagitis, asthma, food allergy and rhinitis.
CONCLUSIONS
The incidence of EoE has increased in Europe over the last 30 years, exceeding increases in the volume of oesophago-gastro-duodenoscopies performed. The patchy and low incidence and prevalence of EoE generally in Europe and compared with North America, may reflect a lack of clinical awareness and research focus rather than a genuinely low incidence of EoE. A co-ordinated Europe-wide study that uses standardised methodology is urgently needed to provide a comprehensive picture of EoE incidence and prevalence across Europe.

Meta-Analysis
BACKGROUND
Depression after abortion is a common problem for all women of reproductive age. However, there are not any data on post-abortion depression at a global level. Consequently, the purpose of this study was to find out the global prevalence of post-abortion depression.
METHODS
The present study involved a comprehensive search of several databases, including Science Direct, Scopus, EMBSE, Google Scholar, and PubMed. The search was conducted between February 1, 2023, and March 10, 2023. The data was extracted using Microsoft Excel (version 14) and analyzed using STATA statistical software. To evaluate publication bias, a forest plot, Begg's test, and Egger's test were employed. Heterogeneity was assessed using I, and a pooled estimated analysis was conducted. Additionally, subgroup analysis was performed based on the study continent/region, World Bank income group, screening instrument, and study design.
RESULTS
This analysis included 15 papers with a total of 18,207 research participants out of a total of 657 articles. The overall pooled prevalence of post-abortion depression was found to be 34.5% (95% CI: 23.34, 45.68), with an I value of 71.6%. The prevalence of post-abortion depression varied based on geographic location, World Health Organization (WHO) regions, World Bank income category, screening approach, and study design. The highest proportion of post-abortion depression was observed in Asia (37.5%), while the WHO's Eastern Mediterranean region had the greatest rate of post-abortion depression (43.1%). Lower-middle-income countries had the highest frequency of post-abortion depression (42.91%) based on World Bank economic classification. The Center of Epidemiological Studies Depression Scale was found to have the highest incidence of reported depression prevalence (30%) across diagnostic tools. Furthermore, the prevalence of depression was higher in cross-sectional study designs (36.42%) compared to cohort studies (22.7%).
CONCLUSION
In conclusion, the occurrence of post-abortion depression has been observed to be widespread globally. The prevalence of post-abortion is found to be influenced by several factors, including the methodology employed in the study, the diagnostic tool utilized, the geographical location, and the socioeconomic status of the population. Healthcare providers should prioritize the provision of post-abortion counseling, care, and emotional support to women.

Meta-Analysis Review
: Severe acute respiratory syndrome coronavirus 2 caused the coronavirus disease of 2019 (COVID-19), which rapidly became a pandemic, claiming millions of lives. Apart from the main manifestations of this infection concerning the respiratory tract, such as pneumonia, there are also many manifestations from the gastrointestinal tract. Of these, bleeding from the gastrointestinal tract is a significant complication quite dangerous for life. This bleeding is divided into upper and lower, and the primary pathophysiological mechanism is the entering of the virus into the host cells through the Angiotensin-converting enzyme 2 receptors. Also, other comorbidities and the medication of corticosteroids and anticoagulants are considered to favor the occurrence of gastrointestinal bleeding (GIB). : This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and the studies were searched in two different databases (Scopus and PubMed) from November 2019 until February 2023. All studies that reported GIB events among COVID-19 patients were included. : 33 studies were selected and reviewed to estimate the prevalence of GIB. A total of 134,905 patients with COVID-19 were included in these studies, and there were 1458 episodes of GIB. The prevalence of GIB, in these 33 studies, ranges from 0.47% to 19%. This range of prevalence is justified by the characteristics of the COVID-19 patients. These characteristics are the severity of COVID-19, anticoagulant and other drug treatments, the selection of only patients with gastrointestinal manifestations, etc. The pooled prevalence of gastrointestinal bleeding was estimated to be 3.05%, rising to 6.2% when only anticoagulant patients were included. : GIB in COVID-19 patients is not a rare finding, and its appropriate and immediate treatment is necessary as it can be life-threatening. The most common clinical findings are melena and hematemesis, which characterize upper GIB. Treatment can be conservative; however, endoscopic management of bleeding with embolization is deemed necessary in some cases.

Meta-Analysis
Immunization is one of the most cost-effective measures to prevent morbidity and mortality in children. Therefore, the purpose of this systematic review and meta-analysis was to determine the pooled prevalence of incomplete immunization among children in Africa as well as its determinants. PubMed, Google Scholar, Scopus, Science Direct, and online institutional repository homes were searched. Studies published within English language, with full text available for searching, and studies conducted in Africa were included in this meta-analysis. A pooled prevalence, Sub-group analysis, sensitivity analysis and meta-regression were conducted. Out of 1305 studies assessed, 26 met our criteria and were included in this study. The pooled prevalence of incomplete immunization was 35.5% (95% CI: 24.4, 42.7), I = 92.1%). Home birth (AOR=2.7; 95% CI: 1.5-4.9), rural residence (AOR = 4.6; 95% CI: 1.1-20.1), lack of antenatal care visit (AOR = 2.6; 95% CI: 1.4-5.1), lack of knowledge of immunizations (AOR=2.4; 95% CI: 1.3-4.6), and maternal illiteracy (AOR = 1.7: 95%CI: 1.3-2.0) were associated with incomplete immunization. In Africa, the prevalence of incomplete immunization is high. It is important to promote urban residency, knowledge of immunization and antenatal follow up care.

Review
Research examining the prevalence and impacts of stalking on mental health professionals (MHPs) has grown over the last two decades. Yet only one previous review has been undertaken examining impacts on staff and focusing on clients as stalkers, with prevalence estimated between 10% and 13%. This systematic review sought to assess prevalence of stalking, and associated impacts and methods of coping reported by MHPs, irrespective of perpetrator type. The search included all healthcare professional groups working in a mental health setting, reported in English or with available translation. Secondary searches were conducted through references cited in primary papers. Of the 7,060 papers identified in five databases, 11 peer-reviewed papers met rigorous inclusion criteria and were quality appraised. Reviewed studies reported prevalence rates between 10.2% and 50%, with higher quality papers reporting a narrower band, 13.9% and 14.3%. However, substantial variability in stalking definitions, and quality of methodology precluded precise prevalence estimation. Participants within the included studies disclosed significant adverse impacts on confidence and competence at work as a consequence of their experiences. Staff invoked substantial workplace and lifestyle changes to mitigate impacts of stalking. However, studies revealed staff disclosed stalking by perpetrators other than clients, notably colleagues and intimate partners, as often or more frequently than by clients. Limitations of the included research and future directions are discussed.
