Our aim is to find out whether vaccines against COVID-19 lead to an immunological response stimulating the production of de novo donor specific antibodies (DSAs) or increase in mean fluorescence intensity (MFI) of pre-existing DSAs in kidney transplant recipients (KTRs). This study involved a detailed literature search through December 2nd, 2023 using PubMed as the primary database. The search strategy incorporated a combination of relevant Medical Subject Headings terms and keywords: \"COVID-19\", \"SARS-CoV-2 Vaccination\", \"Kidney, Renal Transplant\", and \"Donor specific antibodies\". The results from related studies were collated and analyzed. A total of 6 studies were identified, encompassing 460 KTRs vaccinated against COVID-19. Immunological responses were detected in 8 KTRs of which 5 had increased MFIs, 1 had de novo DSA, and 2 were categorized as either having de novo DSA or increased MFI. There were 48 KTRs with pre-existing DSAs prior to vaccination, but one study (Massa et al ) did not report whether pre-existing DSAs were associated with post vaccination outcomes. Of the remaining 5 studies, 35 KTRs with pre-existing DSAs were identified of which 7 KTRs (20%) developed de novo DSAs or increased MFIs. Overall, no immunological response was detected in 452 (98.3%) KTRs. Our study affirms prior reports that COVID-19 vaccination is safe for KTRs, especially if there are no pre-existing DSAs. However, if KTRs have pre-existing DSAs, then an increased immunological risk may be present. These findings need to be taken cautiously as they are based on a limited number of patients so further studies are still needed for confirmation.","PeriodicalId":507039,"journal":{"name":"World Journal of Meta-Analysis","volume":"22 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141334735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vuurberg, Gino M. Kerkhoffs","doi":"10.13105/wjma.v12.i1.87026","DOIUrl":"https://doi.org/10.13105/wjma.v12.i1.87026","url":null,"abstract":"BACKGROUND\u0000 Lateral ankle sprains are the most common traumatic musculoskeletal injuries of the lower extremity, with an incidence rate of 15%-20%. The high incidence and prevalence highlights the economic impact of this injury. Ankle sprains lead to a high socioeconomic burden due to the combination of the high injury incidence and high medical expenses. Up to 40% of patients who suffer from an ankle sprain develop chronic ankle instability. Chronic instability can lead to prolonged periods of pain, immobility and injury recurrence. Identification of factors that influence return to work (RTW) and return to sports (RTS) after a lateral ankle sprain (LAS) may help seriously reduce healthcare costs.\u0000 AIM\u0000 To explore which factors may potentially affect RTW and RTS after sustaining an LAS.\u0000 METHODS\u0000 EMBASE and PubMed were systematically searched for relevant studies published until June 2023. Inclusion criteria were as follows: (1) Injury including LAS or chronic ankle instability; (2) Described any form of treatment; (3) Assessment of RTW or RTS; (4) Studies published in English; and (5) Study designs including randomized controlled clinical trials, clinical trials or cohort studies. Exclusion criteria were: (1) Studies involving children (age < 16 year); or (2) Patients with concomitant ankle injury besides lateral ankle ligament damage. A quality assessment was performed for each of the included studies using established risk of bias tools. Additionally quality of evidence was assessed using the GRADEpro tool in cases where outcomes were included in the quantitative analysis. A best evidence synthesis was performed in cases of qualitative outcome analysis. For all studied outcomes suitable for quantitative analysis a forest plot was created to calculate the effect on RTW and RTS.\u0000 RESULTS\u0000 A total of 8904 patients were included in 21 studies, 10 randomized controlled trials, 7 retrospective cohort studies and 4 prospective cohort studies. Fifteen studies were eligible for meta-analysis. The overall RTS rate ranged were 80% and 83% in the all treatments pool and surgical treatments pool, respectively. The pooled mean days to RTS ranged from 23-93 d. The overall RTW rate was 89%. The pooled mean time to RTW ranged from 5.8-8.1 d. For patients with chronic ankle instability, higher preoperative motivation was the sole factor significantly and independently (P = 0.001) associated with the rate of and time to RTS following ligament repair or reconstruction. Higher body mass index was identified as a significant factor (P = 0.04) linked to not resuming sports or returning at a lower level (median 24, range 20-37), compared to those who resumed at the same or higher level (median 23, range 17-38). Patients with a history of psychological illness or brain injury, experienced a delay in their rehabilitation process for sprains with fractures and unspecified sprains. The extent of the delayed rehabilitation was directly proportional to the increased likel","PeriodicalId":507039,"journal":{"name":"World Journal of Meta-Analysis","volume":"147 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140233770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is now being used not only for diagnosis and staging of liver cirrhosis, but also for outcome prognostication. However, the presence of several confounding factors, especially in critically ill patients, may make interpretation of these results unreliable.

AIM To conduct a systematic review of documented cases of SPS-induced colitis and assess its associated prognosis. METHODS Following the PRISMA-P guidelines, our study employed Medical Subject Headings and Health Sciences Descriptors, skillfully combined using Boolean operators, to conduct comprehensive searches across various electronic databases, including Scopus, Web of Science, MEDLINE (PubMed), BIREME (Biblioteca Regional de Medicina), LILACS (Latin American and Caribbean Health Sciences Literature), SciELO (Scientific Electronic Library Online), Embase, and Opengray.eu. Language criteria were confined to English, Spanish, and Portuguese, with no limitations on the publication date. Additionally, we manually scrutinized the reference lists of retrieved studies. To present our findings, we utilized simple descriptive analysis. RESULTS Our search strategy yielded a total of 442 references. After rigorous evaluation, we included 51 references, encompassing 59 documented cases of colitis. Predominant clinical presentations included abdominal pain, observed in 35 (60.3%) cases, and bloating, reported in 18 (31%) cases. The most frequently affected sites of inflammation were the cecum, rectum, and small intestine, accounting for 31%, 25.8%, and 22.4% of cases, respectively. Colonoscopy findings were described in 28 (48.2%) cases, and 29 (50%) of patients required surgical intervention. Among the subset of patients for whom outcome data was available, 39 (67.2%) experienced favorable outcomes, while 12 (20.6%) unfortunately succumbed to the condition. The mean time required for resolution was 36.7 d, with a range spanning from 1 to 120 d. CONCLUSION SPS demonstrates the capacity to effectively lower serum potassium levels within 24 h. However, this benefit is not without the risk of bowel injury. Our study highlights the absence of high-quality data pertaining to the incidence of adverse events associated with SPS usage, making it challenging to determine whether the potential risks outweigh the benefits. However, a significant mortality rate related to SPS-induced colitis was noted. Future investigations should prioritize randomized controlled trials with a sufficiently large patient cohort to ascertain the true utility and safety profile of this medication.","PeriodicalId":507039,"journal":{"name":"World Journal of Meta-Analysis","volume":"37 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139175492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AIM To provide a comprehensive review and summary of evidence on burnout and anxiety in HCWs during previous global pandemics. METHODS A systematic search on electronic databases such as PubMed Central and MEDLINE was conducted to identify high-quality systematic review studies that reported on the prevalence of burnout and/or anxiety in HCWs during any previous global pandemic. RESULTS Twenty-four high quality systematic review articles were found to be suitable for inclusion. Twenty articles focused merely on Coronavirus disease 2019, while four articles examined multiple pandemics. Burnout was examined in nine articles, while anxiety was examined in the remaining 21 articles. Female HCWs and nurses were identified to be at a higher risk of developing burnout and anxiety during pandemic. We also observed a variation in the prevalence of burnouts and anxiety across different studies due to different mental health instruments were used in different studies. CONCLUSION Nurses and females HCWs had a high prevalence of burnout syndrome and anxiety during pandemic. More emphasis and attention should be paid to safeguarding the psychological well-being of these at-risk populations in the future pandemics.","PeriodicalId":507039,"journal":{"name":"World Journal of Meta-Analysis","volume":"151 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139173398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, they promote angiogenesis through the same neovascularization pathway used physiologically. Angiogenesis is a process characterized by a heterogeneous distribution of oxygen caused by the tumor and oxidative stress; the latter being one of the most powerful stimuli of angiogenesis. As a result of altered tumor metabolism due to hypoxia, acidosis occurs. The angiogenic process and oxidative stress can be detected by measuring serum and tissue biomarkers. The study of the mechanisms underlying angiogenesis and oxidative stress could lead to the identification of new biomarkers, ameliorating the selection of patients with neoplasms and the prediction of their response to possible anti-tumor therapies. In particular, in the treatment of patients with similar clinical tumor phenotypes but different prognoses, the new biomarkers could be useful. Moreover, they may lead to a better understanding of the mechanisms underlying drug resistance. Experimental studies show that blocking the vascular supply results in antiproliferative activity in vivo in neuroendocrine tumor cells, which require a high vascular supply.","PeriodicalId":507039,"journal":{"name":"World Journal of Meta-Analysis","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139339122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
