Meta-Analysis
BACKGROUND
Pelvic organ prolapse can significantly affect a woman's quality of life by compromising physical, social, psychological and sexual function. Pelvic organ disorders and its consequences have higher economic burden to the patient as well to the country. Therefore, this systematic review and met- analysis aimed to estimate the burden of POP in Ethiopia.
METHODS
International databases (MEDLINE/Pub Med, Hinari, Scopus, Google scholar, African journals and literatures were searched and seven eligible cross sectional and two case control studies were included in this systematic review and meta-analysis. Eggers test and funnel plot were computed to check publication bias across the studies. Publication bias was computed using a funnel plot and eggers test. Heterogeneity of the studies was checked using Cochrane Q-test and I statistic. Subgroup analysis was computed for the evidence of heterogeneity.
RESULTS
This systematic review and meta-analysis revealed that the overall national prevalence of pelvic organ prolapse in Ethiopia was 23.52% (95% CI: 61.04, 80.24). Being rural resident (AOR = 3.29; 95% CI: 1.38-7.85), I = 47.5%, P = 0.167), having < 18.5 BMI (AOR = 2.59; 95% CI: 1.53-4.4), I = 59.9%, P = 0.64), and age > 40(AOR = 7.43; 95% CI: 2.27-24.29), I = 75.9%, P = 0.016) were the associated risk factors for pelvic organ prolapse.
CONCLUSIONS
The pooled prevalence of pelvic organ prolapse was high. Residence, body mass index and age of the women were the predictors of pelvic organ prolpase. Creating awareness and identifying the modifiable and non modifiable risk factors for pelvic organ prolpase is a crucial strategy to prevent further complications and risk of operation.

Meta-Analysis
COVID-19 is characterised by systemic immunological perturbations in the human body, which can lead to multi-organ damage. Many of these processes are considered to be mediated by the blood. Therefore, to better understand the systemic host response to SARS-CoV-2 infection, we performed systematic analyses of the circulating, soluble proteins in the blood through global proteomics by mass-spectrometry (MS) proteomics. Here, we show that a large part of the soluble blood proteome is altered in COVID-19, among them elevated levels of interferon-induced and proteasomal proteins. Some proteins that have alternating levels in human cells after a SARS-CoV-2 infection in vitro and in different organs of COVID-19 patients are deregulated in the blood, suggesting shared infection-related changes.The availability of different public proteomic resources on soluble blood proteome alterations leaves uncertainty about the change of a given protein during COVID-19. Hence, we performed a systematic review and meta-analysis of MS global proteomics studies of soluble blood proteomes, including up to 1706 individuals (1039 COVID-19 patients), to provide concluding estimates for the alteration of 1517 soluble blood proteins in COVID-19. Finally, based on the meta-analysis we developed CoViMAPP, an open-access resource for effect sizes of alterations and diagnostic potential of soluble blood proteins in COVID-19, which is publicly available for the research, clinical, and academic community.

Review
INTRODUCTION
Accurate estimations of potential organ donors (POTDs) are required to improve transplant systems. This systematic review analyses current studies on national estimations of potential donors for transplantation as well as the practical and policy implications of detected differences.
METHOD
A systematic review of literature published between 01.01.2010 and 01.04.2020 in PubMed was conducted. Data was extracted into a self-developed matrix, and further data retrieved on national population sizes, waiting lists and transplant activities.
RESULTS
Six studies were included. Investigated populations, underlying data collections and eligibility criteria for POTDs varied widely. Estimated POTDs per million population (p.m.p.) ranged from 25.8 to 333.6, conversion rates from 3.2% to 47.5% leading to 41.2 to 86.4 transplanted organs p.m.p.. Patients on the waiting lists varied from 66.7 to 338.9 p.m.p., defining gaps between organ supply and demand in countries. Not all studies adhered to the definitions and processes of the critical pathway for deceased donation which is the latest international consensus statement on deceased organ donation.
CONCLUSION
Differences in estimated POTDs and differences in supply and demand of donor organs between countries cannot be satisfactorily explained yet due to an obvious lack of evidence, consistent methodology, international consensus and robust underlying datasets. Future studies should be based on robust underlying data sets and aim for potential donor estimations that allow national comparisons due to the adherence to the international consensus on definitions, processes and methodology.

Review
Female pelvic organ prolapse is a common condition associated with significant impact on women's lives from a biopsychosocial perspective. The aim of this systematic review is to identify, appraise and summarize the biopsychosocial profile of women with pelvic organ prolapse. Searches were completed from inception to October 2022 from PubMed, Web of Science, EMBASE, CINAHL, Cochrane, PsycINFO and PEDro using a search string and in line with the Preferred Reporting Information for Systematic reviews and Meta-Analyses protocol. English language studies (randomized controlled trials, cohort studies, case-control studies, qualitative research) investigating female pelvic organ prolapse and using a validated patient-reported outcome measure and validated pelvic organ prolapse objective measurement were examined. Two reviewers independently screened titles, abstracts and full articles for eligibility. Data extraction included participant characteristics, pelvic organ prolapse grading and outcome measures. Risk of bias was assessed using the appropriate Joanna Briggs Institute Tool. Baseline mean score for each questionnaire or questionnaire domain in each category was presented in tertiles (low, moderate and high impact) to allow simple classification of impact. Of 8341 articles identified, 18 were included (n = 2075 women, age range = 22-85 years, parity range = 0-10). One objective outcome measure graded pelvic organ prolapse: Pelvic Organ Prolapse Quantification measurement. Eleven validated patient-reported outcome measures were utilized; two pelvic organ prolapse-specific (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, Pelvic Organ Prolapse Quality of Life Questionnaire), the remainder pelvic health (International Consultation on Incontinence Questionnaire-Vaginal Symptoms, International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, Pelvic Floor Distress Inventory-20, Incontinence Impact Questionnaire-7, Female Sexual Function Index, Urinary Distress Inventory-6, Kings Health Questionnaire, Pelvic Floor Impact Questionnaire-7) or general health questionnaires (Short Form-36). Patient-reported outcome measures included in the review reported moderate levels of pain with sexual intercourse and low levels of bodily pain. Pelvic organ prolapse had a low to moderate impact in sleep/energy and quality of life and sexual function domains. Its impact on physical symptoms and general health perception domains was low. Patient-reported outcome measures results for physical functioning varied from low to high impact. More impact was demonstrated when using pelvic organ prolapse-specific patient-reported outcome measures. There are opportunities for improvement in the use of patient-reported outcome measures in clinical research which would facilitate increased understanding of the biopsychosocial profile of women with pelvic organ prolapse.

Clinical Microbiology and Infection :... Apr 2023Solid organ transplant (SOT) recipients are at increased risks of morbidity and mortality associated with COVID-19. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Solid organ transplant (SOT) recipients are at increased risks of morbidity and mortality associated with COVID-19.
OBJECTIVES
This study aimed to evaluate the immunogenicity of COVID-19 vaccines in SOT recipients.
DATA SOURCES
Electronic databases were searched for eligible reports published from 1 December 2019 to 31 May 2022.
STUDY ELIGIBILITY CRITERIA
We included reports evaluating the humoral immune response (HIR) or cellular immune response rate in SOT recipients after the administration of COVID-19 vaccines.
PARTICIPANTS
SOT recipients who received COVID-19 vaccines.
ASSESSMENT OF RISK OF BIAS
We used the Newcastle-Ottawa scale to assess bias in case-control and cohort studies. For randomised-controlled trials, the Jadad Scale was used.
METHODS
We used a random-effects model to calculate the pooled rates of immune response with 95% CI. We used a risk ratio (RR) with 95% CI for a comparison of immune responses between SOT and healthy controls.
RESULTS
A total of 91 reports involving 11 886 transplant recipients (lung: 655; heart: 539; liver: 1946; and kidney: 8746) and 2125 healthy controls revealed pooled HIR rates after the 1st, 2nd, and 3rd COVID-19 vaccine doses in SOT recipients were 9.5% (95% CI, 7-11.9%), 43.6% (95% CI, 39.3-47.8%) and 55.1% (95% CI, 44.7-65.6%), respectively. For specific organs, the HIR rates were still low after 1st vaccine dose (lung: 4.4%; kidney: 9.4%; heart: 13.2%; liver: 29.5%) and 2nd vaccine dose (lung: 28.4%; kidney: 37.6%; heart: 50.3%; liver: 64.5%).
CONCLUSIONS
A booster vaccination enhances the immunogenicity of COVID-19 vaccines in SOT; however, a significant share of the recipients still has not built a detectable HIR after receiving the 3rd dose. This finding calls for alternative approaches, including the use of monoclonal antibodies. In addition, lung transplant recipients need urgent booster vaccination to improve the immune response.

Review
PURPOSE
Infective endocarditis (IE) is a rare but potentially fatal complication following heart transplantation (HTx). There is a lack of literature regarding the patterns and clinical course of IE development following HTx. We sought to pool the existing data in regards to defining characteristics, management options, and outcomes of IE following HTx.
METHODS
An electronic search of Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, Ovid Medline, and the Scopus databases were performed to identify all articles in the English literature that report IE following HTx in adult patients. Patient-level data were extracted and analyzed.
RESULTS
Systematic search yielded 57 patients from 32 articles. Median patient age was 52 [IQR 43, 59] and 75% of patients (43/57) were male. Median time to IE presentation post-HTx was 8.4 [IQR 3.0, 35.8] months. IE of the mitral valve was observed in 36.8% (21/57) of patients, followed by mural IE in 24.6% (14/57), and tricuspid valve IE in 21.1% (12/57). The most common organisms were Staphylococcus aureus in 26.3% (15/57), Aspergillus fumigatus in 19.3% (11/57), Enterococcus faecalis in 12.3% (7/57), and an undetermined or unspecified organism in 14.0% (8/57) patients. Overall case fatality was 44.6% (25/56). Fungal IE was associated with a significantly higher case fatality 75.0% (9/12) than that of bacterial IE 36.1% (13/36) (p = 0.02). Surgical management of post-HTx IE was observed in 35.1% (20/57) of patients. This included valve surgery for 70.0% (14/20), including the mitral valve in 50.0% (7/14), aortic valve in 35.7% (5/14), and the tricuspid valve in 14.3% (2/14) of patients.
CONCLUSION
In addition to bacterial organisms, fungi also represent a frequent cause of IE in post-HTx patients. Overall HTx patient survival in the setting of IE is poor and may be worse if caused by A. fumigatus.

Review
Consensus remains elusive in the definition and indications of multivisceral transplantation (MVT) within the transplant community. MVT encompasses transplantation of all organs reliant on the celiac artery axis and the superior mesenteric artery in different combinations. Some institutions classify MVT as involving the grafting of the stomach or ascending colon in addition to the jejunoileal complex. MVT indications span a wide spectrum of conditions, including tumors, intestinal dysmotility disorders, and trauma. This systematic review aims to consolidate existing literature on MVT cases and their indications, providing an organizational framework to comprehend the current criteria for MVT.

Progres En Urologie : Journal de... Nov 2016To review ethical, legal and technical aspects of living kidney donor surgery. (Review)
Review
OBJECTIVES
To review ethical, legal and technical aspects of living kidney donor surgery.
MATERIAL AND METHODS
An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: Donor nephrectomy; Kidney paired donation; Kidney transplantation; Laparoscopic nephrectomy; Living donor; Organs trafficking; Robotic assisted nephrectomy; Vaginal extraction. French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. A total of 6421 articles were identified; after careful selection, 161 publications were considered of interest and were eligible for our review.
RESULTS
The ethical debate focuses on organ shortage, financial incentive, organ trafficking and the recent data suggesting a small but significant increase risk for late renal disease in donor population. Legal decisions aim to increase the number of kidneys available for donation, such as kidney-paired donation that faces several obstacles in France. Laparoscopic approach became widely used, while robotic-assisted donor nephrectomy failed to demonstrate improved outcome as compared with other minimal invasive techniques.
CONCLUSION
Minimally invasive living donor nephrectomy aims to limit side effects in the donor without increasing the morbidity in this specific population of healthy persons; long term surveillance to prevent the onset of renal disease in mandatory.

Bone marrow (BM) is an organ responsible for crucial processes in living organs, e. g., hematopoiesis. In recent years, Organ-on-a-Chip (OoC) devices have been used to satisfy the need for in vitro systems that better mimic the phenomena occurring in the BM microenvironment. Given the growing interest in these systems and the diversity of developed devices, an integrative systematic literature review is required. We have performed this review, following the PRISMA method aiming to identify the main characteristics and assess the effectiveness of the devices that were developed to represent the BM. A search was performed in the Scopus, PubMed, Web of Science and Science Direct databases using the keywords (("bone marrow" OR "hematopoietic stem cells" OR "haematopoietic stem cells") AND ("organ in a" OR "lab on a chip" OR "microfluidic" OR "microfluidic*" OR ("bioreactor" AND "microfluidic*"))). Original research articles published between 2009 and 2020 were included in the review, giving a total of 21 papers. The analysis of these papers showed that their main purpose was to study BM cells biology, mimic BM niches, model pathological BM, and run drug assays. Regarding the fabrication protocols, we have observed that polydimethylsiloxane (PDMS) material and soft lithography method were the most commonly used. To reproduce the microenvironment of BM, most devices used the type I collagen and alginate. Peristaltic and syringe pumps were mostly used for device perfusion. Regarding the advantages compared to conventional methods, there were identified three groups of OoC devices: perfused 3D BM; co-cultured 3D BM; and perfused co-cultured 3D BM. Cellular behavior and mimicking their processes and responses were the mostly commonly studied parameters. The results have demonstrated the effectiveness of OoC devices for research purposes compared to conventional cell cultures. Furthermore, the devices have a wide range of applicability and the potential to be explored.

INTRODUCTION
Immunosuppressant drugs are increasingly being used in the reproductive years. Theoretically, such medications could affect fetal health either through changes in the sperm DNA or through fetal exposure caused by a presence in the seminal fluid. This systematic overview summarizes existing literature on the spermatotoxic and genotoxic potentials of methotrexate (MTX), a drug widely used to treat rheumatic and dermatologic diseases, and mycophenolate mofetil (MMF), which alone or supplemented with ganciclovir (GCV) may be crucial for the survival of organ transplants.
MATERIAL AND METHODS
The systematic overview was performed in accordance with the PRISMA guidelines: A systematic literature search of the MEDLINE and Embase databases was done using a combination of relevant terms to search for studies on spermatotoxic or genotoxic changes related to treatment with MTX, GCV or MMF. The search was restricted to English language literature, and to in vivo animal studies (mammalian species) and clinical human studies.
RESULTS
A total of 102 studies were identified, hereof 25 human and 77 animal studies. For MTX, human studies of immunosuppressive dosages show transient effect on sperm quality parameters, which return to reference values within 3 months. No human studies have investigated the sperm DNA damaging effect of MTX, but in other organs the genotoxic effects of immunosuppressive doses of MTX are fluctuating. In animals, immunosuppressive and cytotoxic doses of MTX adversely affect sperm quality parameters and show widespread genotoxic damages in various organs. Cytotoxic doses transiently change the DNA material in all cell stages of spermatogenesis in rodents. For GCV and MMF, data are limited and the results are indeterminate, for which reason spermatotoxic and genotoxic potentials cannot be excluded.
CONCLUSIONS
Data from human and animal studies indicate transient spermatotoxic and genotoxic potentials of immunosuppressive and cytotoxic doses of MTX. There are a limited number of studies investigating GCV and MMF.
