In an era where male infertility poses significant challenges for many couples, intracytoplasmic sperm injection (ICSI) is becoming increasingly common. Microscopic evaluation of sperm head morphology can contribute to the development of healthier embryos. A comprehensive literature search was conducted using the PubMed, Scopus, Web of Science, and Cochrane databases. A meta-analysis was performed following the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) for randomized controlled trials. Eligible studies were selected based on the PICOS (Population, Intervention, Comparison/Comparator, Outcomes, Study type) model. The pregnancy outcomes considered after artificial reproductive technology (ART) procedures included the fertilization rate (FR), high-quality embryo rate (HQER), implantation rate (IR), and clinical pregnancy rate (CPR). This study was registered on PROSPERO (CRD42023423108). Of 105 records evaluated, three studies met the inclusion criteria. Our analysis indicated that birefringence sperm selection significantly improved HQER and IR after ART, although no significant differences were observed for FR and CPR. The use of birefringence for sperm selection in ICSI cycles may represent a straightforward strategy to improve ART outcomes, particularly for couples with abnormal sperm parameters.

Objective: Cyclophosphamide (CP), a chemotherapeutic agent, has been shown to inhibit spermatogenesis. Accordingly, the primary objective of this study was to evaluate the potential therapeutic benefits of quercetin‑loaded nanoselenium (quercetin‑loaded selenium nanoparticles [SeNPs]) in mice treated with CP. Methods: Thirty‑five adult male mice were randomly assigned to five groups (n=7 per group): control, quercetin‑loaded SeNPs (20 mg/kg, daily for 5 weeks), CP (200 mg/kg, single dose), treatment A (CP+quercetin‑loaded SeNPs), and treatment B (CP+quercetin, 20 mg/kg daily for 5 weeks). Sperm parameters, DNA fragmentation index, catalase activity, levels of glutathione (GSH), glutathione disulfide (GSSG), malondialdehyde (MDA), and reactive oxygen species (ROS) were evaluated in all groups, along with histological assessments of testicular tissue. Results: In CP‑treated mice, administration of quercetin‑loaded SeNPs (treatment A) significantly improved sperm parameters, including total count, motility, morphology, and DNA integrity. Treatment also markedly increased the numbers of spermatogonia, primary spermatocytes, spermatids, Sertoli cells, and Leydig cells in testicular tissue. Furthermore, treatment with quercetin‑loaded SeNPs resulted in a significant increase in catalase activity and GSH levels while significantly reducing GSSG, MDA, and ROS levels in CP‑induced testicular damage. Conclusion These findings suggest that quercetin‑loaded SeNPs enhance spermatogenesis in a CP‑induced mouse model by improving the antioxidant profile and testicular stereological parameters.

Purpose: The integration of video-based learning into surgical education highlights the need for high-quality instructional content, especially for complex procedures such as percutaneous nephrolithotomy (PCNL). This study aimed to systematically evaluate and compare the educational quality of YouTube videos demonstrating supine and prone PCNL techniques. Materials and Methods: A comprehensive YouTube search was conducted between January 6 and 19, 2025, using the keywords “supine PCNL,” “prone PCNL,” “supine percutaneous nephrolithotomy,” and “prone percutaneous nephrolithotomy.” Eligible videos were assessed using three validated scoring systems: Global Quality Score (GQS), the DISCERN instrument (a validated tool for assessing the quality of health information), and the JAMA (Journal of the American Medical Association) criteria, along with a novel tool, the PCNL-Edu Score (educational score). A total of 120 videos (60 supine, 60 prone) were included. Results: Supine PCNL videos demonstrated significantly higher DISCERN reliability scores (p=0.037), GQS scores (p=0.001), and PCNL-Edu Scores (p=0.018) compared to prone PCNL videos. Subgroup analyses showed no significant differences in educational quality based on video source (academic/individual) or video type (educational/surgical demonstration). In correlation analyses, video length positively correlated with PCNL-Edu Scores in both groups (prone: p=0.004, supine: p=0.001), whereas popularity metrics such as views (prone: p=0.069, supine: p=0.061) and likes (prone: p=0.183, supine: p=0.225) were not significantly associated with educational quality. Conclusions Supine PCNL videos currently offer superior instructional quality on YouTube. The PCNL-Edu Score provides a focused framework for evaluating surgical videos and underscores the need for standardized guidelines to improve video-based surgical education.

Introduction: Obstructive sleep apnoea (OSA) is characterised by recurrent pharyngeal collapses that occur five or more times per hour of sleep or more and reduce or completely block airflow for at least 10 seconds. Obesity predis-poses individuals to and potentiates OSA. Materials and methods: As a pre- and post-training activity measure, 30 obese people between the ages of 25 and 45 were asked to complete the STOP-BANG questionnaire and a 6-minute walk test. After that, they engaged in aerobic activity. Results: The scores for the six-minute walk test and the stop-bang questionnaire were 0.0005 and 0.0003, respectively with a “p” value- ≤0.001 (significant). In our investigation, the effects of aerobic exercise on exercise tolerance and obstructive sleep apnoea were significantly different. Con-clusion: Aerobic exercise is a better intervention for increasing exercise tolerance and obstructive sleep apnoea in obese patients. This intervention may be a significant contributor to cardiorespiratory fitness and can be considered a useful tool for enhancing quality of life.

Abstract Hyperkalemia (serum potassium >5.0 mEq/l) is a significant complication in patients with heart failure, chronic kidney disease, and diabetes mellitus, particularly when treated with renin-angiotensin-aldosterone system inhibitors (RAASi). Both hyperkalemia and RAASi interruption are associated with increased cardiovascular events, hospitalizations, and mortality. This expert opinion document, developed between January and December 2024 through a systematic process, aims to establish guidance for hyperkalemia treatment in Indonesian patients with cardiorenal diseases receiving RAASi therapy, addressing the unique challenges within the Indonesian healthcare context. A comprehensive literature review of international guidelines and regional studies was conducted by a panel of 11 expert specialists (3 cardiologists, 6 internist-nephrologists, and 2 internist-cardiologists), who evaluated 29 statements covering diagnosis, monitoring, prevention, and treatment of hyperkalemia. Of the 29 statements, 26 reached consensus: 17 statements achieved very high agreement (≥90%) and 9 attained high agreement (≥67% – <90%). The agreed statements covered key areas, including potassium monitoring frequency, RAASi dose optimization strategies, dietary modifications, and treatment thresholds. Three statements regarding alternative therapeutic approaches did not receive agreement (<67%) due to limited local availability and cost considerations. Key recommendations include structured monitoring protocols for high-risk patients, strategies for RAASi dose optimization while managing hyperkalemia risk, and specific interventions adapted to local resources. This document provides a practical approach for managing hyperkalemia in Indonesian patients with cardiorenal diseases while maintaining optimal RAASi therapy, considering local Indonesian healthcare resources and constraints.

We report a case of a previously healthy 9-year-old boy who presented to the emergency department following accidental ingestion of 35% hydrogen peroxide. He developed emesis and mild abdominal pain and was found to have extensive portal venous gas, severe gastric pneumatosis, and free intraperitoneal air on a computed tomography scan. He was transferred to an outside hospital for hyperbaric oxygen therapy, with no emergency surgical intervention indicated. This case highlights the dangers of ingesting even a small amount of concentrated hydrogen peroxide in children and underscores the safe storage practices at home.

Thioacetamide (TAA)-induced liver fibrosis, triggered by inflammation and oxidative stress, is prompted by hepatic stellate cells (HSCs) activation via several pathways. This study explores the hepatoprotective effect of aloe vera gel (AVG) extract and bone marrow mesenchymal stem cells (BM-MSCs) transplantation on regulating long intergenic noncoding RNA (lincRNA-p21) and microRNA (miR-17-5p) expressions and their impact on TGF-β1/Smad-3 and Wnt-10a/ β-Catenin cascades in TAA-induced liver damage. The study involved 48 adult male albino rats divided into four groups:control, TAA, TAA treated with BM-MSCs, and TAA treated with BM-MSCs+AVG extract. After 8 weeks, liver enzymes and hepatic oxidative parameters were evaluated alongside lincRNA-p21, miR-17-5p, TGF-β1, Smad-3, Wnt-10a, and β-Catenin expressions. Liver tissue sections were examined by light and electron microscopes and analyzed morphometrically. Group II showed increased aspartate aminotransferase, alanine aminotransferase, malondialdehyde, reduced glutathione levels, and deteriorated hepatocytes with distorted mitochondria and dilated rough endoplasmic reticulum. Group IV restored lincRNA-p21 expression, which downregulated miR-17-5p and suppressed activated HSCs by inhibiting TGF-β1/Smad-3 and Wnt-10a/β-Catenin pathways, and improved hepatic tissue architecture. Additionally, immunohistochemically, alpha-smooth muscle actin and cyclin D1 expressions were markedly decreased in group IV compared to group II. We concluded that AVG suppresses fibrotic pathways, boosts BM-MSCs differentiation, and reduces HSCs activation in liver fibrosis caused by TAA.

Background: The Ascertain Dementia 8-item Questionnaire (AD8) is a validated informant-based interview for early dementia detection. Research suggests the utility of self-rated AD8 to identify milder dementia forms in research settings. This study compares the factor structure, reliability, and diagnostic performance between AD8-Self and AD8-Informant for early cognitive impairment (ECI) in a clinical setting. Methods: Five hundreds fifteen patient-informant dyads (43 cognitively intact and 472 ECI) from a tertiary memory clinic completed both self-reported and informant AD8. We conducted exploratory factor analysis to determine the factor structure, Cronbach’s alpha for internal consistency, and receiver operating characteristic (ROC) curve analysis for ECI, including a subgroup analysis for mild cognitive impairment (MCI). Results: The mean age and education of ECI participants were 75.61 years (range, 51–95) and 5.6 years (range, 0–20), respectively, and 72.6 years (range, 51–89) and 6.8 years (range, 0–16) in the MCI subgroup. Unlike AD8-Informant’s one-factor structure, AD8-Self had a two-factor structure corresponding to memory and non-memory domains. AD8-Self demonstrated lower reliability (Cronbach’s alpha: ECI 0.666 vs. 0.764; MCI 0.663 vs. 0.709). In ECI, AD8-Informant (cutoff score ≥3) showed better diagnostic performance (sensitivity 89%, specificity 79%) than AD8-Self (cutoff score ≥4; sensitivity 27.1%, specificity 95.3%) (AUC 0.915 vs. 0.593; p<0.001). Similar results were found in MCI (sensitivity 64.7% vs. 26.5%; specificity 79.1% vs. 95.3%; AUC 0.745 vs. 0.600; p=0.002). Conclusion AD8-Self has a distinct factor structure, lower reliability, and inferior diagnostic performance compared to AD8-Informant for ECI/MCI detection. Our result do not support AD8-Self as a standalone tool for detecting ECI or MCI.

Background: s/Aims: Portal vein embolization (PVE) and Yttrium-90 (Y-90) radioembolization are used to induce liver hypertrophy, increasing future liver remnant volume and reducing the risk of post-resection liver failure. This systematic review compares the effectiveness of PVE and Y-90 radioembolization in promoting liver hypertrophy in patients undergoing liver resection. Methods: A systematic review was conducted in accordance with PRISMA guidelines. PubMed, Embase, Cochrane, and Web of Science were searched for studies published between January 2000 and August 2023. Studies comparing PVE and Y-90 radioembolization with respect to liver hypertrophy were included. Risk of bias was assessed using the Newcastle–Ottawa Scale. Pooled mean differences were calculated using an inverse-variance random-effects model. Results: Of 1,965 studies identified, three retrospective cohort studies met inclusion criteria, comprising 125 patients. Among these, 67.3% underwent PVE and 32.7% received Y-90 radioembolization. Hepatocellular carcinoma was the most common diagnosis (55.9%), followed by metastatic disease (32.3%) and cholangiocarcinoma (11.8%). PVE was more commonly used as a preoperative strategy for liver resection, while Y-90 radioembolization was primarily employed for palliative intent. One study reported greater hypertrophy with Y-90 compared to PVE (63% vs. 36%); however, hypertrophy was assessed over a longer interval (150 vs. 30 days). In pooled analysis, PVE was associated with significantly greater hypertrophy (mean difference 23.75%; 95% CI 12.02–35.48; p < 0.0001; I 2 = 48%). Conclusions Evidence directly comparing PVE and Y-90 radioembolization for liver hypertrophy remains limited. While pooled results favor PVE, procedure selection should be individualized based on clinical context.
