RESUMEN
Background: Alcohol use disorder (AUD) is a significant source of end-stage liver disease and liver failure and an indication for liver transplant (LT). Historically, LT for alcoholic liver disease (ALD) required 6 months of alcohol abstinence. Recently, it has been demonstrated that early LT (< 6 months of abstinence) in strictly selected group of patients provides survival benefit while keeping the relapse to harmful drinking at acceptable levels. This practice has been reflected in the Dallas consensus, but more data are needed to appropriately risk stratify the patient from the perspective of return to harmful alcohol drinking post-transplant. This "6-month rule" has been highly debated and recent data demonstrated that the duration of pre-transplant sobriety is not related with an increased risk of relapse to alcohol post-transplant. We performed a meta-analysis to compare the rate of alcohol relapse in individuals having standard vs. early LT. Methods: MEDLINE and SCOPUS were searched for randomized controlled trials (RCTs), observational studies, and case-control studies from their inception through June 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMSA) 2009 checklist guidelines were followed for this meta-analysis. Studies comparing post-transplant outcomes, such as alcohol relapse, in individuals following standard vs. early LT, were included. Reviews, case studies, conference abstracts, clinical trials with only an abstract, and studies with inadequate data for extraction were all disqualified. The data were retrieved, gathered, and examined. The random effects model was used to generate forest plots. For the analysis, a P-value of 0.05 was considered significant. Results: Thirty-four studies were discovered in the initial search. Three studies were included in this systematic review and meta-analysis incorporating 367 patients. Mean age was 51.7 years. Out of 367 patients, 173 (47%) underwent early LT. Out of three studies included, one study demonstrated decreased probability of alcohol relapse in patients undergoing early LT, whereas the other two showed the opposite result. All of the included studies were analyzed and had minimal risk of bias. Pooled analysis demonstrates that the difference in alcohol relapse between early vs. standard LT was insignificant (odds ratio: 1.24, 95% confidence interval: 0.75 - 2.06, P = 0.40). Conclusion: Our results show that early LT is not associated with increased risk of alcohol relapse post-transplant when compared with a mandatory 6-month abstinence period. Hence, individuals with ALD should not be categorically rejected from LT merely on the criteria of 6 months of abstinence. Other selection criteria based on the need and post-transplant outcomes should be utilized.
RESUMEN
OBJECTIVE: Transcatheter aortic valve replacement (TAVR) is a successful treatment for aortic stenosis (AS) patients, and previous studies indicate favorable outcomes for those with concomitant aortic stenosis and transthyretin-associated cardiac amyloidosis (TTRCA-AS). However, the impact of TAVR on more adverse outcomes in TTRCA-AS patients compared to those with AS alone is still uncertain, with conflicting findings reported in the literature. METHODS: PubMed and Scopus were extensively searched from inception till August 2021. Studies were included if they reported data for prevalence and outcomes including mortality and cardiovascular-related hospitalization events in TTRCA-AS patients referred for TAVR. The data for these outcomes were pooled using a random effects model and forest plots were created. RESULTS: After initially screening 146 articles, 6 were shortlisted for inclusion in our analysis. Pooled analysis demonstrated a 13.3% [95% CI: 10.9-16.5; p = 0.307] prevalence of TTRCA in patients with AS undergoing TAVR. The incidence of mortality and cardiovascular (CV) hospitalization in patients with TTRCA-AS undergoing TAVR were 28.3% [95% CI: 18.7-39.0, p = 0.478] and 21.1% [95% CI: 10.2-34.5, p = 0.211], respectively. CONCLUSION: The overall pooled TTRCA-AS prevalence was reported to be 13.3% in AS patients who underwent TAVR. Furthermore, transthyretin-associated CA was found to be associated with an increased risk of mortality and hospitalization. Large patient population studies are required to assess the safety and efficacy of TAVR in TTRCA-AS patients, as current research report data from small patient cohorts.

Objectives: Preeclampsia is one of the most frequent pregnancy disorders, with a global incidence of 2%-8%. Serum 25-hydroxyvitamin D is an essential mineral for human health; some studies suggest link between 25-hydroxyvitamin D deficiency and preeclampsia, while others offer contradictory findings. Thus, the goal of this study is to evaluate the relationships between maternal 25- hydroxyvitamin D concentrations and the risk of preeclampsia. In addition to this, our study also evaluates the effects of 25- hydroxyvitamin D supplementation on the incidence of preeclampsia. Therefore, assessing 25- hydroxyvitamin D's potential as a possible intervention to lower the risk of preeclampsia. Methods: The Medline database was queried from inception until July 2021 for randomized controlled trials and observational studies without any restrictions. The studies assessing the association between 25-hydroxyvitamin D deficiency and preeclampsia and the impact of 25-hydroxyvitamin D supplementation on the incidence of preeclampsia were incorporated. The results were reported using a random-effects meta-analysis and the Mantel-Haenszel odds ratio. A p-value of <0.05 was considered significant for the analysis. Results: This analysis includes 34 papers, including 10 randomized controlled trials and 24 observational studies. According to our pooled analysis, 25-hydroxyvitamin D supplementation was significantly associated with a lower risk of preeclampsia in pregnant women (OR: 0.50; 95% CI: 0.40-0.63; p = 0.00001), while 25-hydroxyvitamin D deficiency was significantly associated with an increased risk of preeclampsia (OR: 4.30; 95 % CI: 2.57-7.18; p < 0.00001, OR: 1.71; 95 % Cl: 1.27-2.32; p = 0.0005, OR 1.61; 95 % Cl: 1.21-2.16; p = 0.001). Conclusion: Results suggest that 25-hydroxyvitamin D has a significant relationship with preeclampsia as confirmed by the findings that low maternal 25-hydroxyvitamin D concentrations cause increased risk of preeclampsia while 25-hydroxyvitamin D supplementation reduces the incidence of preeclampsia. Our findings indicate that 25-hydroxyvitamin D supplementation can be used as a possible intervention strategy in preventing one of the most common causes of maternal mortality around the world, preeclampsia.
RESUMEN
Background To study the prevalence and types of hypertension-mediated organ damage and the prognosis of patients presenting to the emergency department (ED) with hypertensive emergencies. Methods and Results PubMed was queried from inception through November 30, 2021. Studies were included if they reported the prevalence or prognosis of hypertensive emergencies in patients presenting to the ED. Studies reporting data on hypertensive emergencies in other departments were excluded. The extracted data were arcsine transformed and pooled using a random-effects model. Fifteen studies (n=4370 patients) were included. Pooled analysis demonstrates that the prevalence of hypertensive emergencies was 0.5% (95% CI, 0.40%-0.70%) in all patients presenting to ED and 35.9% (95% CI, 26.7%-45.5%) among patients presenting in ED with hypertensive crisis. Ischemic stroke (28.1% [95% CI, 18.7%-38.6%]) was the most prevalent hypertension-mediated organ damage, followed by pulmonary edema/acute heart failure (24.1% [95% CI, 19.0%-29.7%]), hemorrhagic stroke (14.6% [95% CI, 9.9%-20.0%]), acute coronary syndrome (10.8% [95% CI, 7.3%-14.8%]), renal failure (8.0% [95% CI, 2.9%-15.5%]), subarachnoid hemorrhage (6.9% [95% CI, 3.9%-10.7%]), encephalopathy (6.1% [95% CI, 1.9%-12.4%]), and the least prevalent was aortic dissection (1.8% [95% CI, 1.1%-2.8%]). Prevalence of in-hospital mortality among patients with hypertensive emergency was 9.9% (95% CI, 1.4%-24.6%). Conclusions Our findings demonstrate a pattern of hypertension-mediated organ damage primarily affecting the brain and heart, substantial cardiovascular renal morbidity and mortality, as well as subsequent hospitalization in patients with hypertensive emergencies presenting to the ED.

BACKGROUND/AIMS: Colonoscopy for screening is associated with unpleasant experiences for patients, and abdominal compression devices have been developed to minimize these problems. However, there is a paucity of data supporting the therapeutic benefits of this strategy. This study examined the effects of using an abdominal compression device during colonoscopy on the cecal intubation time (CIT), abdominal compression, patient comfort, and postural changes. METHODS: We searched PubMed and Scopus (from inception to November 2021) for randomized controlled trials that assessed the effects of an abdominal compression device during colonoscopy on CIT, abdominal compression, patient comfort, and postural change. A random-effects meta-analysis was performed. Weighted mean differences (WMDs) and Mantel-Haenszel odds ratios (ORs) were calculated. RESULTS: Our pooled analysis of seven randomized controlled trials revealed that abdominal compression devices significantly reduced CIT (WMD, -0.76 [-1.49 to -0.03] minutes; p=0.04), abdominal compression (OR, 0.52; 95% confidence interval [CI], 0.28-0.94; p=0.03), and postural changes (OR, 0.46; 95% CI, 0.27-0.78; p=0.004) during colonoscopy. However, our results did not show a significant change in patient comfort (WMD, -0.48; 95% CI, -1.05 to 0.08; p=0.09) when using an abdominal compression device. CONCLUSION: Our findings demonstrate that employing an abdominal compression device may reduce CIT, abdominal compression, and postural change but have no impact on patient comfort.
RESUMEN
OBJECTIVE: Polycystic Ovary Syndrome is the most prevalent hormonal disorder in females. Over the years, metformin (MET) has become the first-line choice of treatment; however, due to its gastrointestinal side effects, a more recent drug, myo-inositol (MI), has been introduced. We aim to conduct a systematic review and meta-analysis to compare the effects of MET and MI on hormonal and metabolic parameters. MATERIALS AND METHODS: Authors extensively searched PubMed, Scopus, Cochrane Library, Google Scholar, and Web of Science for randomized clinical trials (RCTs) until August 2021. Eight (n = 8) articles were included, with a total sample size of 1088, of which 460 patients received MET, 436 received MI, and 192 received a combination of both. Standard mean differences (SMDs) and Confidence Intervals (CIs) were used for data synthesis, and forest plots were made using Review Manager 5.4 for Statistical Analysis using the random-effect model. RESULTS: The meta-analysis indicates that there is no significant difference between MET and MI in terms of their effects on BMI (SMD = 0.16, 95% CI: - 0.11 to 0.43, p = 0.24), fasting insulin (SMD = 0.00, 95% CI: - 0.26 to 0.27, p = 0.97), fasting blood sugar (SMD = 0.11, 95% CI: - 0.31to 0.53, p = 0.60), HOMA index (SMD = 0.09, 95% CI: - 0.20 to 0.39, p = 0.50), and LH/FSH (SMD = 0.20, 95% CI: - 0.24 to 0.64, p = 0.37). BMI, fasting blood sugar, and LH/FSH ratio reported moderate heterogeneity because of the varying number of study participants. CONCLUSION: Our meta-analysis comparing hormonal and metabolic parameters between MET and MI did not show much significant difference, indicating both drugs are equally beneficial in improving metabolic and hormonal parameters in patients with PCOS.

Background: Suicide is a global health concern. There are reproductive health-related factors that are responsible for increasing the risk of female suicide. There are a number of studies examining the association between suicide and the menstrual cycle, but still, there are no conclusive findings. Aim: We aimed to pool data from all the studies reporting data on suicides and the menstrual cycle phase to report the following outcomes: incidence of suicidal deaths in the menstrual, secretory, and proliferative phases, and to find out whether the burden of suicide in the menstrual phase in particular, was more at a young age (18-35 years) or middle age (36-50years). Methods: The PubMed database was extensively searched from inception till 12th April 2022. The data for the number of events occurring for each outcome were pooled using random-effects model and forest plots were created. Results: Five articles were shortlisted for inclusion in our analysis. Incidence of suicide in the secretory phase was highest at 45.2% [95% CI, 0.367-0.537]. The incidence of suicide, when occurring in the menstrual phase, was reported to be 68.4% (95 CI, 0.317-1.052) and 31.6% (95 CI, -0.052.3-0.68) for young-aged and middle-aged victims, respectively. Conclusion: Our results demonstrate that the menstrual phase has a lower risk of mortality due to suicide when compared to the other two phases of the menstrual cycle. Nevertheless, when suicide occurred in the menstrual phase, the incidence of suicide among the younger age-group was higher than for those in the middle age-group.
RESUMEN
High-intensity interval training (HIIT) is a novel training approach that improves cardiopulmonary fitness and functional capacity in numerous chronic conditions, however its impact in patients with heart failure (HF) with preserved ejection fraction (HFpEF) is uncertain. We evaluated data from prior studies reporting the effects of HIIT versus moderate continuous training (MCT), on cardiopulmonary exercise outcomes in patients with HFpEF. PubMed and SCOPUS were queried from inception till February 1st, 2022 for all randomized controlled trials (RCT) comparing the effect of HIIT versus MCT in patients with HFpEF on peak oxygen consumption (peak VO2), left atrial volume index (LAVI), respiratory exchange ratio (RER), and ventilatory efficiency (VE/CO2 slope). A random-effects model was applied, and the weighted mean difference (WMD) of each outcome was reported with 95% confidence intervals (CI). Three RCTs (total Nâ¯=â¯150 patients with HFpEF), with a follow-up of 4 to 52 weeks were included in our analysis. Our pooled analysis demonstrated that HIIT significantly improved peak VO2 (WMDâ¯=â¯1.46 mL/kg/min (0.88, 2.05); P < 0.00001; I2â¯=â¯0%), as compared to MCT. However, no statistically significant change was demonstrated for LAVI (WMDâ¯=â¯-1.71 mL/m2 (-5.58, 2.17); Pâ¯=â¯0.39; I2â¯=â¯22%), RER (WMDâ¯=â¯-0.10 (-0.32, 0.12); Pâ¯=â¯0.38; I2â¯=â¯0%), and VE/CO2 slope (WMDâ¯=â¯0.62 (-1.99, 3.24); Pâ¯=â¯0.64; I2â¯=â¯67%) in patients with HFpEF. Across current RCT data, HIIT, compared to MCT, had a significant impact on improving peak VO2. Conversely, there was no significant change in LAVI, RER, and VE/CO2 slope between HFpEF patients undertaking HIIT as opposed to MCT.

BACKGROUND AND AIM: Von Willebrand disease (VWD) is considered the most prevalent inherited bleeding disorder. The current study aims to demonstrate the research status and trends on VWD worldwide. METHODS: Bibliometric analysis was used to investigate the global research productivity and trends on VWD. The publications on VWD from 1956 to 2021 were extracted using the Web of Science database. In the VWD domain, a total of 3,643 records were analyzed for authorship and collaboration patterns, yearly productivity, highly cited documents, relevant source of publication, most prolific scholars, productive countries, and organizations. RESULTS: The most productive journal, author, organization, and country were 'Haemophilia' with 439 publications, 'Favaloro EJ' with 119 publications, the 'University of Milan' with 192 publications, and the United States of America (USA) with 1,048 publications, respectively. The document with the highest citations was 'Srivastava A, 2013, Haemophilia,' which received 1,154 citations in total. In 2016, the highest number of publications shared by two author patterns was 28. With 199 publications, the year 2021 remained on the top, while the citation-wise analysis identified 2006 as the top year with 5,379 citations. CONCLUSIONS: Research productivity and publication trends on VWD revealed that the USA emerged as the most significant contributing country. The 'University of Milan' was the most significant contributing organization, while 'Favaloro EJ' was the most significant author. 'Hemophilia' was found to be the most significant journal in the field of VWD. It is recommended that researchers from countries with significant contributions to the field should collaborate with researchers from Asian countries and other countries that lack behind in research in the domain of VWD.(www.actabiomedica.it).

BACKGROUND: Endothelial dysfunction serves as an early marker for the risk of cardiovascular disease (CVD); therefore, it is a site of therapeutic interventions to reduce the risk of CVD. AIMS: To examine the effect of the Mediterranean diet (MedDiet), as an intervention, on structural and functional parameters of endothelial function, and how it may reduce the risk of CVD and associated mortality. METHODS: Medline database was searched for randomized controlled trials. Random-effects meta-analysis was conducted on 21 independent datasets. Meta-regression and subgroup analysis were performed to assess whether the effect of MedDiet was modified by health status (healthy subjects or with increased CVD risk), type of MedDiet intervention (alone or combined), type of parameter (functional or structural), study design (cross-over or parallel), BMI, age, and study duration. Our study used sample size, mean, and standard deviation of endothelial function measurements for both MedDiet intervention and control in the analyses. RESULTS: Inverse relationship between endothelial function and intake of MedDiet was observed (SMD: 0.34; 95% CI: 0.16, 0.52; P = 0.0001). Overall, MedDiet increased FMD by 1.39% (95% CI: 0.47, 2.19; P < 0.001). There was a significant improvement in endothelial function in both healthy patients and in those with an increased risk of CVD. No significant variation was observed in the effects of MedDiet on endothelial function, due to study design or type of intervention. CONCLUSIONS: These findings support that MedDiet can reduce the risk of CVD by improving endothelial function.

Objectives: Our study aims to assess knowledge and understanding of FM among doctors employed at a tertiary care hospital in Karachi, Pakistan with a focus on its diagnostic criteria, treatment modalities, and general knowledge of symptoms. Study Design: Cross-sectional Study. Methods: Our cross-sectional study recruited participants through convenience sampling. A total of 104 participants responded, which included (a) House Officers, (b) Medical Officers, and (c) Residents. A structured questionnaire was used, and an electronic form was generated which was then emailed to the participants to acquire their responses. Results: The majority (66.3%) of our respondents were female and the median age was 26 years. A majority (93.3%) accepted FM as a separate and distinct clinical identity, and 79.8% were confident in recognizing its general symptoms. Widespread pain (95.2%) and fatigue (80.8%) were correctly identified as most commonly observed symptoms. Moreover, 68.3% of respondents possessed no knowledge of both ACR 1990 and 2010 diagnostic criteria for FM. Of those aware, majority favored using the most recent ACR 2010 criteria (72.7%). Majority of our respondents (75%) preferred using pharmaceutical and non-pharmaceutical interventions simultaneously in the treatment. Conclusions: Our study indicates that while physicians have satisfactory knowledge of the symptoms and treatment modalities of FM, a knowledge gap concerning its diagnostic criteria exists. Proper treatment can only be successful when physicians successfully diagnose FM, therefore, future training programs should use this fact as a stepping stone for advances in its healthcare.
