Objectives: There is conflicting evidence about the efficacy of statin use in regard to clinical outcomes in patients with coronavirus disease 2019 (COVID-19). A systematic review and meta-analysis was performed to examine the effect of statin use on mortality in COVID-19 patients. Methods: The electronic databases were searched, from inception to March 3, 2021. Unadjusted and adjusted effect estimates with their 95% confidence intervals (95% CI) were pooled using random-effects models. Results: Twenty-five cohort studies involving 147 824 patients were included. The mean age of the patients ranged from 44.9 to 70.9 years; 57% of patients were male and 43% were female. The use of statins was not associated with mortality when applying the unadjusted risk ratio (uRR 1.16, 95% CI 0.86–1.57; 19 studies). In contrast, meta-analyses of the adjusted odds ratio (aOR 0.67, 95% CI 0.52–0.86;...

Aims: Differentiation between patients with Takotsubo syndrome and acute coronary syndrome (ACS) remains a challenge. We performed a systematic review to identify and evaluate diagnostic predictive models to distinguish both conditions. Methods and results: We performed an electronic search in PubMed, EMBASE, and Scopus until January 2024. Observational studies that developed and/or validated multivariable diagnostic models to differentiate Takotsubo syndrome from ACS were included. The risk of bias was assessed using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). We conducted a narrative synthesis of the performance measures of the diagnostic models evaluated in each study. In addition, a random-effects meta-analysis of the c-statistic with its 95% confidence interval (CI) of the InterTAK model was performed. Of 1015 articles, a total of 11 studies (n = 4552) were included...

Background: Fluid therapy plays a critical role in the management of acute pancreatitis. Normal saline (NS) is commonly used in these patients. However, Lactate Ringer’s (LR) has also been shown to be useful for this condition. Aim: To assess the effect of LR compared to NS in patients with acute pancreatitis. Methods: We searched in three electronic databases from inception to December 2020 for randomized controlled trials (RCTs). Outcomes were mortality, intensive care unit (ICU) admission, hospital stay, and Systemic Inflammatory Response Syndrome (SIRS) at 24, 48, and 72 h. The risk of bias was assessed using the Risk of Bias 2.0 tool. All meta-analyses were performed using a random-effects model. Results: Four RCTs comprising 248 patients were included. The mean age ranged from 42.3 to 63.8 years and 49% of patients were men. Patients treated with LR had similar risk of mortality ...

Objective: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB). Materials and methods: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a random-effects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach. Results: Eight full-text RCTs and two RCT abstracts were included (n=1513)...

Peripartum cardiomyopathy (PPCM) is a potentially life-threatening condition that can occur during the late pregnancy or puerperium. A 31-year-old woman with a recent twin pregnancy presented with heart failure symptoms nine days postpartum. On admission, she had volume overload and hemodynamic compromise, which was rapidly reversed with inotropic levosimendan support. Echocardiography revealed a left ventricular ejection fraction (LVEF) of 20% with global hypokinesia. Once stabilized, she was discharged on heart failure medication, bromocriptine, and warfarin. Cardiac magnetic resonance imaging at five weeks demonstrated a preserved LVEF of 57% and no evidence of myocardial scarring or edema. During the 4-year follow-up, the patient remained stable with no new pregnancies. This case highlights the importance of considering PPCM in the differential diagnosis of heart failure in the perip...

Introduction and aim: Pancreatobiliary tumours are challenging to diagnose exclusively by imaging methods. Although the optimum moment for carrying out the EUS is not well defined, it has been suggested that the presence of biliary stents may interfere with the proper staging of tumours and the acquisition of samples. We performed a meta-analysis to evaluate the impact of biliary stents on EUS-guided tissue acquisition yield. Material and methods: We conducted a systematic review in different databases, such as PubMed, Cochrane, Medline, and OVID Database. A search was made of all studies published up to February 2022. Results: Eight studies were analyzed. A total of 3185 patients were included. The mean age was 66.9 ± 2.7 years; 55.4% were male gender. Overall, 1761 patients (55.3%) underwent EUS guided tissue acquisition (EUS-TA) with stents in situ, whereas 1424 patients (44.7%) unde...

En ocasiones, no es posible realizar una colecistectomía debido a que el paciente no es apto para la cirugía, y se debe optar por un manejo no quirúrgico. En estos pacientes, el manejo no quirúrgico puede ser a través del drenaje transhepático percutáneo de la vesícula o bien el drenaje ecoendoscópico de la misma. En el presente trabajo decidimos comparar la eficacia y seguridad de ambas técnicas en el manejo no quirúrgico de pacientes con colecistitis aguda. Métodos: Se realizó una revisión sistemática en diferentes bases de datos, como PubMed, OVID, Medline y Cochrane Databases. Este metanálisis considera estudios publicados hasta septiembre de 2021. Se seleccionaron seis estudios (2 estudios aleatorizados controlados). Estos estudios incluyeron 749 pacientes. La edad media fue de 72,81 ± 7,41 años, y los varones representaron el 57,4%. El éxito técnico del drenaje ...

Occasionally, cholecystectomy is not possible because the patient is not suitable for surgery, and non-operative management should be performed. In these patients, the non-operative management can be through the percutaneous transhepatic gallbladder drainage (PTGBD) or the endoscopic gallbladder drainage. We decided to compare the efficacy and safety of PTGBD and EUS-GBD in the non-operative management of patients with acute cholecystitis. We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published until September 2021. Six studies were selected (2 RCTs). These studies included 749 patients. The mean age was 72.81 ±7.41 years, and males represented 57.4%. EUS-GBD technical success was lower than PTGBD (RR, 0.97; 95% CI, 0.95-0.99), whereas clinical success and adverse events rates were sim...

Early enteral nutrition through a feeding tube is essential for the management of severe acute pancreatitis (SAP). Nasojejunal tube nutrition has been preferred on the assumption that it provided pancreatic rest in comparison to the nasogastric tube. However, nasojejunal tube placement is complex, may delay feeding initiation and can increase hospital costs. Our aim was to compare the efficacy and safety of enteral feeding with a nasogastric tube versus nasojejunal tube in patients with SAP. We searched four databases (PubMed, Web of Science, Scopus, and Embase) until December 1, 2022. We included randomized controlled trials (RCTs) comparing enteral feeding by nasogastric and nasojejunal tubes in patients with SAP. Primary outcome was all-cause mortality. Secondary outcomes were organ failure, infection, complications, surgical intervention, duration of tube feeding and length of hospit...
