Background/Objectives: Non-invasive fibrosis scores are widely used for risk stratification in metabolic dysfunction–associated steatotic liver disease (MASLD); however, their performance in obese individuals remains controversial. The Fibrosis-4 index (FIB-4) is commonly recommended as a first-line tool, yet may underestimate fibrosis risk in severe obesity. The BAST score, which incorporates metabolic and anthropometric parameters, has been proposed as an alternative. This study aimed to characterize both the degree and direction of discordance between FIB-4 and BAST in obese patients with MASLD. Methods: This predefined secondary analysis included 2,950 adults with obesity (BMI ≥30 kg/m²) and MASLD from the multicenter OBREDI-TR cohort. Fibrosis risk categories were assigned using standard cut-offs for FIB-4 and BAST. Agreement was assessed using weighted Cohen’s kappa. Associations between discordance patterns, obesity class, and visceral adiposity index (VAI) were evaluated using chi-square tests and general linear models. Results: Overall agreement between FIB-4 and BAST was very poor (κ = 0.041, p < 0.001). Discordance was observed in 22.3% of patients and increased markedly with obesity severity. In class III obesity, discordance was predominantly driven by low-risk classification according to FIB-4 despite high-risk classification by BAST. Patients with this discordant pattern exhibited significantly higher VAI values compared with concordant cases (p < 0.001), independent of study center. Conclusions: In obese patients with MASLD, particularly those with morbid obesity, FIB-4 frequently classifies patients as low risk while BAST identifies elevated fibrosis risk. This systematic discordance suggests that FIB-4 may underestimate fibrosis burden in the context of severe obesity and visceral adiposity, supporting the need for a phenotype-oriented, multimodal approach to fibrosis risk assessment.

Objectives: We investigated the effects of Continuous Positive Airway Pressure (CPAP) on blood pressure (BP) and vigilance in taxi drivers with obstructive sleep apnea (OSA). Methods: Taxi drivers aged ≥60 years were recruited for polysomnography. Those diagnosed with OSA underwent 6 months of CPAP therapy. Baseline and follow-up assessments included 24-hour ambulatory blood pressure monitoring (ABPM) and the psychomotor vigilance test (PVT). Results: Among the 32 participants, 22 (68.8%) were diagnosed with OSA (median age 63.0 [62.0–65.0] years; 21 males). The average CPAP adherence was 3.1±2.3 hours per night, with 23.5% using CPAP for more than 4 hours per night. There were no significant changes in 24-hour mean systolic ABPM (125.9 [116.8–134.9] mmHg to 126.0 [118.3–133.7] mmHg; p=0.93) or reaction times measured by PVT (2.0 [0.0–3.0] lapses to 2.0 [1.0–3.0] lapses; p=0.82) after CPAP therapy. Conclusion: A high prevalence of OSA was observed among taxi drivers. CPAP adherence was suboptimal and did not result in significant improvements in BP or vigilance.

Background: Apelin-36 may be used to identify patients with ST-segment elevation myocardial infarction (STEMI) who are at risk for the no-reflow phenomenon. Patients presenting with STEMI were evaluated and stratified according to their apelin-36 levels. Methods: In this study, 161 patients presenting with STEMI within 12 hours of symptom onset and undergoing primary percutaneous coronary intervention (pPCI) were enrolled. Biochemical parameters, including apelin-36, troponin T, creatine kinase (CK), the MB fraction of creatine kinase (CK-MB), total cholesterol, triglycerides, and other routine laboratory parameters, were measured. Blood samples for apelin-36 measurement were collected prior to PCI, centrifuged to obtain serum, and preserved at -80⁰C until being assayed. Two-dimensional echocardiography was performed in all patients. Thereafter, patients were divided into two groups according to their level of Apelin-36. Results: Among the 161 consecutive STEMI patients, 115 (71.42%) had Apelin-36 levels ≤0.58ng/mL (group 1), whereas 46 (28.57%) had Apelin-36 levels >0.58ng/mL (group 2). In total, 51 (31.67%) STEMI patients experienced no-reflow phenomenon after PCI: 29 (18.01%) patients with apelin-36 ≤ 0.58ng/mL and 22 (13.66%) with a value > 0.58ng/mL (p < 0.001). In terms of Gensini score, the mean value in group 1 was (70.29 (±28.76), while in group 2, it was 81.95 (±23.82) (p=0.004). Overall, a positive correlation between apelin-36 and Gensini score was observed in both groups using Kendall’s correlation analysis (group 1: Figure 2, p=0.05; group 2: Figure 2, p<0.0001). Binary logistic regression analysis identified apelin-36 and diabetes mellitus as significant predictors at the 5% level, with p-values of 0.045 and 0.036, respectively. Patients with apelin-36 levels ≤ 0.58ng/mL had troponin T levels of 290.0 (8.5-9510.0), while those with a value > 0.58ng/mL had troponin T levels of 132.15 (9.4-5190.0) (p < 0.012). The receiver operating characteristics (ROC) curve of apelin-36 was used to plot the true positive rate against the false positive rate at different cut-off points, with AUC=0.67 (95% CI, 0.57-0.76), and the cut-off value for apelin-36 was 0.58ng/mL, with p=0.001. Conclusions: Significant associations were observed between apelin-36 and no-reflow phenomenon in patients with STEMI. An apelin-36 cut-off value of 0.58ng/mL, measured at admission, could be used to identify patients who were at increased risk of no-reflow phenomenon/reperfusion injury.

Robotic-Assisted Versus Laparoscopic Surgery for Colorectal Resection in Oncologic Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials (2025)
Hussein Mussa Muafa
,Malika Abdu Balkam
Background: Robotic-assisted surgery (RAS) is increasingly used for colorectal cancer (CRC), but its clinical and oncologic advantages over conventional laparoscopy (LS) remain uncertain. Prior meta-analyses have included overlapping RCTs but vary in methodology, scope, and analytical transparency. This review aims to provide an updated, independently re-analyzed synthesis of RCTs published from 2015–2025, with full PRISMA compliance, explicit analytic reproducibility, and expanded evaluation of bias and evidence certainty. Methods: A systematic review and meta-analysis was conducted according to PRISMA guidelines. The protocol was retrospectively registered in PROSPERO (Registration ID: CRD420251237158). PubMed, Embase, and Cochrane CENTRAL were searched (January 1, 2015–January 31, 2025). Full reproducible search strings, PICOS criteria, and inclusion/exclusion rules were predefined. Only RCTs comparing RAS vs LS for malignant colorectal disease were included. Data extraction was performed independently by two reviewers. Meta-analyses used DerSimonian–Laird random-effects models; standardized procedures were applied for converting medians/IQRs into means/SDs and for continuity corrections in zero-event trials. Risk of bias was assessed using Cochrane RoB 2.0, and evidence certainty was graded using GRADE. Results: A total of 12 RCTs encompassing 3,107 patients met the inclusion criteria. RAS resulted in significantly lower conversion-to-open rates (OR 0.42; 95% CI 0.28–0.63; I²=18%) compared with LS. Operative time was consistently longer with RAS (MD +23.8 minutes; 95% CI 14.2–33.4; I²=67%). Overall postoperative complications (Clavien–Dindo ≥II) were comparable (OR 0.91; 95% CI 0.76–1.13; I²=22%). Length of stay showed a small but significant reduction with RAS (MD −0.8 days; 95% CI −1.3 to −0.2; I²=49%). Pathologic outcomes showed lower circumferential resection margin (CRM) positivity with RAS (OR 0.59; 95% CI 0.41–0.85). Lymph node retrieval was slightly higher with RAS (MD +0.71 nodes; 95% CI 0.25–1.18). Distal margins and TME completeness were equivalent. No RCT reported mature long-term oncologic outcomes; evidence remains limited to short-term surrogates. Conclusions: In contemporary RCTs, RAS provides fewer conversions and slightly better pathologic surrogates, while maintaining similar morbidity compared to LS. The main trade-off remains longer operative time and higher resource use. True oncologic equivalence cannot be confirmed until long-term RCT data mature. Advanced imaging (e.g., SOMATOM Force CT), age-specific MIS evidence, and the emergence of endoluminal robotic systems are likely to shape future refinements in technique and patient selection.

Restrictive vs Liberal Fluid Strategy for Initial Resuscitation in Sepsis and Septic Shock: A Systematic Review and Meta-Analysis (2025)
Hussein Mussa Muafa
,Malika Abdu Balkam
Background: Fluid resuscitation is a cornerstone in the management of sepsis and septic shock, yet the optimal strategy remains controversial. Liberal strategies may restore tissue perfusion quickly but can increase the risk of fluid overload, pulmonary edema, and organ dysfunction. Restrictive strategies aim to limit fluid accumulation while maintaining adequate perfusion. Objective: This systematic review and meta-analysis aims to synthesize randomized controlled trials (RCTs) comparing restrictive versus liberal fluid strategies in adults with sepsis or septic shock, focusing on mortality, ICU outcomes, renal outcomes, and fluid balance. Methods: A comprehensive search was conducted in PubMed, Scopus, Web of Science, and Cochrane Library up to October 2025. RCTs comparing restrictive versus liberal fluid strategies in adult patients were included. Data were extracted for mortality, ICU length of stay, ventilator-free days, renal replacement therapy (RRT), and cumulative fluid balance. Risk of bias was assessed using Cochrane RoB 2, and evidence certainty using GRADE. Meta-analysis was performed using random-effects models. Results: Twelve RCTs comprising 8,743 patients were included. Restrictive strategies reduced cumulative fluid balance and showed trends toward fewer ventilator and ICU days. Mortality differences between groups were not statistically significant. Conclusions: Restrictive fluid resuscitation is safe and may reduce complications associated with fluid overload without adversely affecting survival. Individualized, hemodynamic-guided fluid management remains recommended.

Background/Objectives: Metabolic dysfunction–associated steatotic liver disease (MASLD) is now the leading cause of chronic liver disease globally, mirroring the increasing prevalence of obesity, insulin resistance, and type 2 diabetes. Early detection of hepatic steatosis is vital for cardiometabolic risk assessment; however, conventional imaging is costly and impractical for population screening. This study aimed to develop interpretable machine-learning models to predict ultrasound-detected MASLD using routinely available clinical and biochemical data. Methods: We analyzed data from 644 adults (50% with MASLD on ultrasonography). Preprocessing, imputation, and feature selection were implemented within a single scikit-learn pipeline to avoid information leakage. An Elastic Net–regularized logistic regression identified the top 20 predictors, which were subsequently used across nine supervised machine learning (ML) classifiers. Model performance was evaluated via repeated stratified 5-fold cross-validation (25 resamples) using accuracy, F1 score, sensitivity, specificity, Youden’s J, balanced accuracy, and Area Under the Receiver Operating Characteristic Curve (AUROC). Interpretability was assessed using SHapley Additive exPlanations (SHAP). Results: Participants with MASLD exhibited greater adiposity, insulin resistance, and dyslipidemia compared with controls [p < 0.05 for body mass index (BMI), waist circumference, glucose, HbA1c, triglycerides). Elastic Net selection highlighted Weight, Ponderal Index, Fibrosis-4 Index (FIB-4), blood urea nitrogen (BUN)/Creatinine ratio, Aspartate Aminotransferase to Platelet Ratio Index (APRI), and Visceral Adiposity Index as the strongest predictors. Logistic Regression and Gradient Boosting achieved the best performance (accuracy = 0.65 ± 0.03; AUROC = 0.71 ± 0.04; balanced accuracy = 0.66 ± 0.06), outperforming rule-based indices such as Fatty Liver Index (FLI) and Hepatic Steatosis Index (HSI) reported in the literature. SHAP analysis confirmed clinically coherent feature effects, with higher anthropometric and hepatic injury indices increasing predicted MASLD probability. Conclusions: Routinely available clinical and biochemical parameters can predict hepatic steatosis with moderate accuracy using transparent, interpretable ML models. Logistic Regression and Gradient Boosting provided the best discrimination and generalizability, offering a pragmatic, low-cost approach for early MASLD screening in primary and metabolic care settings.
