Changes in ACL T2* Metrics Over the Course of the Female Menstrual Cycle: A New Biomarker for the ACL Injury Risk?

BACKGROUND: Sex-based disparities in the anterior cruciate ligament (ACL) injury risk may be partly explained by cyclic variations in sex hormones that drive systemic shifts in tissue osmoregulation. Ultrashort echo time (UTE) T2* magnetic resonance imaging provides a noninvasive, quantitative means of evaluating the water content and collagen orientation in tissue. HYPOTHESIS: Eumenorrheic female participants will exhibit significant ACL T2* changes across the cycle, while anovulatory control participants will demonstrate no significant changes over time. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 25 women with no prior knee injuries were enrolled: 10 premenopausal, eumenorrheic participants and 15 anovulatory control participants (6 postmenopausal and 9 premenopausal using oral contraceptives). Bilateral knee magnetic resonance imaging was performed at 4 time points evenly spaced over 1 month, with the first visit within 24 hours of menses onset. Ovulation status was confirmed using commercially available ovulation predictor kits. Three-dimensional UTE sequences (11 echoes; 0.03-25 ms) were acquired to evaluate bicomponent ACL T2* metrics. Linear mixed-effects models assessed temporal differences in long and short T2* values, and the Cohen d quantified effect size. RESULTS: Eumenorrheic participants demonstrated significantly shorter preovulatory long T2* values compared with postovulatory values (mean difference, 1.0 ms [95% CI, 0.2-1.9 ms]; P = .015; Cohen d = 0.51). No significant temporal differences were observed for any T2* metric in anovulatory controls. CONCLUSION: Eumenorrheic female participants exhibited significant preovulatory to postovulatory changes in ACL T2* metrics, while anovulatory controls demonstrated no significant changes over time. These findings suggest that ACL T2* metrics are sensitive to cyclic fluctuations in female sex hormones across the menstrual cycle.

Risk factors and management strategies for needle disengagement from the visual field in pediatric robot-assisted laparoscopic pyeloplasty.

OBJECTIVE: This study aimed to identify risk factors for suture needle disengagement from the visual field during pediatric robot-assisted laparoscopic pyeloplasty (RALP) and propose effective strategies for prevention and management. METHODS: A retrospective cohort study analyzed clinical data from 339 pediatric patients who underwent RALP for ureteropelvic junction obstruction (UPJO) at a single institution between August 2017 and December 2020. Patients were categorized based on the occurrence of needle disengagement from the visual field. Various patient demographics and surgical procedural factors were evaluated. Univariate and multivariate logistic regression, along with LASSO regression, identified independent risk and protective factors. RESULTS: Needle disengagement occurred in 38 (11.21%) of 339 cases. Multivariate logistic regression identified five independent risk factors for needle disengagement: use of a 3-mm auxiliary trocar (OR = 4.69, 95% CI: 1.98-12.53, P < 0.001), non-standard needle holder use (OR = 2.32, 95% CI: 1.04-5.18, P = 0.038), unshaped suture needles (OR = 3.16, 95% CI: 1.44-7.19, P = 0.005), simultaneous use of &#x2265;2 intra-abdominal sutures (OR = 2.46, 95% CI: 1.15-5.48, P = 0.023), and clamping the needle shank during withdrawal (OR = 3.42, 95% CI: 1.40-8.21, P = 0.006). Conversely, sufficient assistant experience (>10 cases) was identified as a protective factor (OR = 0.39, 95% CI: 0.18-0.88, P = 0.021). CONCLUSION: Suture needle disengagement from the visual field during pediatric RALP is associated with specific technical and instrumental factors. Implementing targeted strategies-such as mandating specialized needle holders, preoperative needle shaping, a single-needle workflow, prioritizing clamping the suture thread over the needle shank during withdrawal, and ensuring adequate assistant training-has the potential to significantly reduce significantly mitigate the risk of needle loss and enhance overall surgical safety in pediatric RALP.

Non-genetic Risk Factors for Allopurinol-Induced Severe Cutaneous Adverse Reaction (SCAR): A Systematic Review.

BACKGROUND: Allopurinol-induced severe cutaneous adverse reactions (SCARs) are rare but potentially life threatening, particularly in Asian populations. While the genetic marker HLA-B*58:01 is a well-established risk factor, non-genetic factors may also contribute. This systematic review synthesizes evidence on associations between non-genetic risk factors and allopurinol-induced SCAR. METHODS: We searched MEDLINE, Scopus, Cochrane Library and Web of Science from inception to 29 June 2026 for observational studies examining non-genetic risk factors for SCAR, defined as Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis, Acute Generalised Exanthematous Pustulosis, or Hypersensitivity Syndrome/Drug Reaction with Eosinophilia and Systemic Symptoms. Adults aged &#x2265;&#xa0;18 years were included. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random-effects model; heterogeneity was assessed with I2. Mean differences were calculated for continuous variables. NIH Study Quality Assessment Tool was used for quality assessment of the studies. RESULTS: Twenty-six studies were included. Female sex (20 studies; 3340 SCAR cases, 562,647 controls) was associated with an increased risk of allopurinol-induced SCAR (OR 2.06; 95% confidence interval (CI) 1.25-3.38). Chronic kidney disease (16 studies; 1625 SCAR cases, 553,804 controls) was also significantly associated with SCAR (OR 3.78; 95% CI 1.99-7.17). Five studies (177 SCAR cases, 1368 controls) reported higher allopurinol doses among SCAR cases than tolerant controls (mean difference 19.61 mg; 95% CI 2.97-36.24). No significant associations were observed for age or concomitant diuretic use in the primary meta-analyses. Substantial heterogeneity was observed across studies. Sensitivity analyses demonstrated consistent findings for most factors, although concomitant diuretic use became significantly associated with SCAR after exclusion of non-Asian and zero-event studies. CONCLUSION: CKD, female sex, and higher allopurinol dose were identified as significant non-genetic risk factors for allopurinol-induced SCAR. These findings support consideration of non-genetic factors alongside pharmacogenomic screening in future risk-stratification strategies. However, substantial heterogeneity and potential publication bias limit the certainty of the available evidence. Well-designed studies evaluating non-genetic predictors as primary outcomes are needed to develop robust integrated risk prediction models for clinical decision making.

F-URS with FANS versus mPCNL for 2-3&#x2009;cm UUTS: a RCT with a subgroup analysis of 2-2.5&#x2009;cm stones.

OBJECTIVE: To evaluate the safety and efficacy of flexible ureteroscopy (f-URS) with a flexible and navigable suction ureteral access sheath (FANS) compared with mini-percutaneous nephrolithotomy (mPCNL) in the treatment of 2-3&#x2009;cm upper urinary tract stones (UUTS), with a prespecified subgroup analysis for stones &#x2265;2 to <2.5&#x2009;cm. METHODS: This randomized controlled trial enrolled 326 patients with 2-3&#x2009;cm UUTS between June 2023 and December 2025. Patients were randomly assigned in a 1:1 ratio to undergo either f-URS with FANS or mPCNL. A prespecified subgroup analysis was conducted for stones measuring &#x2265;2 to <2.5&#x2009;cm. The primary outcomes were the immediate and 1-month stone-free rate (SFR). Secondary outcomes included the operative duration, decrease in haemoglobin, hospital stay, and complication rate. RESULTS: The baseline characteristics were comparable between the two groups. In the overall 2-3&#x2009;cm cohort, the FANS group achieved immediate and 1-month SFRs comparable to those of the mPCNL group. Although the operative time was longer in the FANS group, it was associated with significantly less haemoglobin loss and a shorter hospital stay, with no significant difference in infection-related complications. Notably, in the subgroup of stones &#x2265;2 to <2.5&#x2009;cm, the FANS group demonstrated a non-inferior SFR at both time points, and the operative time was not significantly longer than that of the mPCNL group. CONCLUSION: For 2-3&#x2009;cm UUTS, f-URS with FANS offers a SFR comparable to that of mPCNL, along with the advantages of reduced blood loss and shorter hospitalization. In the &#x2265;2 to <2.5&#x2009;cm subgroup, FANS shows comprehensive benefits over mPCNL. These findings support FANS as an effective alternative to mPCNL for 2-3&#x2009;cm stones and a potentially preferred option for stones measuring 2-2.5&#x2009;cm.

A profile of deaths in children at the Diepkloof Forensic Pathology Services mortuary in Gauteng, South Africa from 1 January 2019 to 31 December 2020.

This retrospective study was conducted to address the scarcity of knowledge regarding unnatural child deaths in South Africa. This was done by analysing cases admitted to the Diepkloof Forensic Pathology Services mortuary between 1 January 2019 and 31 December 2020. Data from FPS death registers and FPS case files were used to profile: (1) the incidence, causes and manner of death, circumstances of death, and ancillary investigations performed at autopsy; and (2) to assess the impact of the COVID-19 pandemic on trauma-related child deaths. Of 4&#x202f;704 decedents, 535 (11.4%) were children, predominantly male (55.5%) and Black (94.8%). Accidental deaths were the most common manner of death (42.6%), primarily due to road traffic accidents, burns, and aspiration. Homicides accounted for 6.5% of all deaths in children, most frequently involving sharp force or gunshot injuries. Cranio-cerebral injuries predominated in trauma-related deaths. In 2020, compared to preceding years, with the implementation of the COVID-19 restrictions, there was a decrease in trauma-related child fatalities. These findings suggest that many child deaths are potentially preventable through government implementation of improved safety interventions and community education.

Retrograde intrarenal surgery with flexible and navigable suction access sheaths vs mini-percutaneous nephrolithotomy for large upper urinary tract stones: a&#xa0;systematic review and meta-analysis.

OBJECTIVE: To conduct a meta-analysis comparing the efficacy and perioperative outcomes of contemporary flexible and navigable suction access sheath-assisted retrograde intrarenal surgery (FANS-RIRS) against percutaneous nephrolithotomy (PCNL) for the management of large upper urinary tract stones, as despite technological advances in RIRS such as high-powered lasers and FANS that have substantially enhanced its performance, current guidelines continue to recommend&#x2009;PCNL as first-line treatment for renal stones >2cm. METHODS: MEDLINE, Embase, and the Cochrane Library were searched for studies performing direct comparisons of FANS-RIRS against PCNL in adult patients until September 2025. Primary outcomes included stone-free rates (SFRs) and need for ancillary procedures. Secondary outcomes included operative time, length of postoperative hospitalisation, and postoperative complications. RESULTS: A total of 10 studies (three randomised control trials, seven retrospective cohort studies) comprising 2347 patients were included; preoperative stone sizes were predominantly 2-3&#x2009;cm. All PCNL procedures in the studies included were performed as mini-PCNL. The SFRs for FANS-RIRS were comparable with mini-PCNL across all stone sizes (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.70-1.17) and stones &#x2265;2&#x2009;cm (OR 0.80, 95% CI 0.60-1.08), with low heterogeneity. Ancillary procedures rates were similar (OR 1.22, 95% CI 0.61-2.44). FANS-RIRS was associated with significantly fewer overall complications, specifically smaller haemoglobin decline, need for transfusion, and shorter hospital stay. However, mini-PCNL demonstrated shorter operative times for stones &#x2265;2&#x2009;cm. Urosepsis rates were low and similar between both groups. Limitations include predominance of Asian studies, variability of practice, and inclusion of non-randomised studies. CONCLUSIONS: Contemporary FANS-RIRS achieves SFRs comparable to mini-PCNL even for 2-3&#x2009;cm stones, while offering superior safety profiles and shorter hospitalisation; this supports FANS-RIRS as a viable primary treatment in selected patients.

Psychological skills training for sport-related outcomes: An umbrella review of evidence credibility and methodological quality.

Psychological skills training (PST) is widely used in sport, but review-level evidence remains fragmented across interventions, populations, outcomes, and methodological standards. This umbrella review synthesized evidence on PST-related interventions for sport-related outcomes, including athletic performance, psychological outcomes, cognitive performance, and sports injury, and evaluated evidence credibility, certainty, and methodological quality. A systematic literature search was conducted on 21 May 2025 in MEDLINE, PsycInfo, PubMed, Scopus, SportDiscus, Web of Science, and CINAHL Complete. Overall, 61 reviews involving 42,106 participants were included; 35 meta-analyses involving 28,076 participants were eligible for quantitative synthesis, and 26 reviews or meta-analyses involving 14,030 participants were summarized qualitatively. Quantitative findings showed generally positive point estimates for mindfulness-based interventions, imagery practice, music-based interventions, neurofeedback, perceptual-cognitive training, and multiple PST interventions, but most findings were weak or non-significant and certainty was generally very low. Qualitative evidence suggested potential benefits, but conclusions varied according to intervention definition, delivery, outcome measurement, and methodological quality. Evidence was more developed for athletic performance and psychological outcomes than for cognitive performance and sports injury. Overall, PST-related interventions may benefit sport-related outcomes, but conclusions should remain cautious because of low certainty, methodological heterogeneity, and limited evidence credibility.

Prevalence and pattern of psychological symptoms in form of dental fear and anxiety in children and adolescents with traumatic dental injuries: a systematic review.

BACKGROUND/AIMS: This systematic review aimed to evaluate the level and pattern of dental fear and anxiety (DFA) amongst children and adolescents with traumatic dental injuries (TDI) and, where available, to compare these outcomes with non-traumatised controls. METHODS: An a priori protocol was developed and registered in PROSPERO (CRD420261329946). A comprehensive literature search was conducted in PubMed, EMBASE, Web of Science, and Scopus on 3 March 2026, with additional grey literature, citation, and reference searching. No language or time restrictions were applied. Observational clinical studies assessing DFA in individuals with TDI using validated tools were included. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Joanna Briggs Institute checklist. Certainty of evidence was evaluated using the GRADE approach. RESULTS: A total of 2885 records were identified, of which 4 cross-sectional studies met the inclusion criteria after screening. Studies were conducted in Croatia and Kosovo and included paediatric populations. Sample sizes ranged from 147 to 505 participants. Different validated scales (CFSS-DS, CDAS, S-DAI) were used to assess DFA. Overall, children with TDI demonstrated predominantly low levels of dental fear and anxiety across assessment tools. However, findings were inconsistent, with some studies reporting lower or similar anxiety levels in TDI patients compared to controls. Risk of bias was moderate or high in three of the four studies, and the overall certainty of evidence was rated as low to very low due to methodological limitations, heterogeneity, and imprecision. CONCLUSION: The limited available evidence suggests that children and adolescents with TDI do not consistently present with higher levels of dental fear and anxiety than non-traumatised controls. These findings indicate that TDI does not inherently cause DFA, underscoring the critical role of empathetic behaviour support in mitigating post-traumatic dental fear. However, the evidence is based on a small number of regionally concentrated cross-sectional studies with low to very low certainty. Future prospective studies using standardised TDI classifications, validated DFA instruments, and clearly defined assessment time points are needed.

Analysis of end-stage renal disease mediated by cuproptosis-related genes.

OBJECTIVE: The complex pathophysiological mechanism of end-stage renal disease (ESRD) has not been fully understood. Cuproptosis is a newly discovered type of programmed cell death. Therefore, this study attempts to clarify the relationship between cuproptosis-related genes (CRGs) and the phenotype of ESRD. MATERIALS AND METHODS: The National Center for Biological Information Gene Expression Omnibus database was applied to obtain the GSE37171 dataset comprising whole-genome microarray analysis of peripheral blood samples. A 3&#xa0;:&#xa0;1 case-control design was employed with 75 ESRD patients and 20 healthy controls who were frequency-matched for age, sex, and ethnicity. Based on differentially expressed genes (DEGs) and genes related to cuproptosis, CRGs were identified. Thereafter, we explored two different subpopulations based on the cuproptosis gene and analyzed their expression and immune infiltration. Genes specific to the CRG cluster were identified through the weighted gene co-expression network analysis algorithm, and the best prediction model was determined and verified by four machine learning methods. RESULTS: The study identified 14 differentially expressed CRGs, among which ATP7B, SLC31A1, LIAS, LIPT1, DLD, MTF1, CDKN2A, DBT, and DLST had relatively high expression levels in the ESRD samples. Compared with the control group, expression levels of FDX1, DLAT, PDHA1, PDHB, and GLS were significantly lower in the ESRD group, and CRGs played a key role in the regulation of immune infiltration in ESRD. Two cuproptosis-related molecular clusters were identified in the ESRD samples. Cluster2 was more correlated with the immune infiltration of ESRD. By analyzing the intersection points between CRG cluster and key genes of ESRD, a total of 888 specific DEGs were identified. Functional differences related to specific DEGs were further explored using gene set variation analysis. Five significant genes (SMC5, USP47, USP53, AGA, and DMXL1) were identified by the support vector machine model as key predictors for ESRD disease risk, achieving an area under the curve (AUC) of 1.00 in internal validation. However, external validation in independent cohorts is required prior to clinical application. Individual gene analysis showed an AUC >&#xa0;0.81 in discriminating ESRD patients from healthy controls, and the expression of all 5 genes in ESRD patients was significantly lower than in the control group. CONCLUSION: This study clarified the relationship between CRGs and the phenotype of ESRD, analyzed their specific roles in the immune microenvironment, and obtained a predictive model, providing new insights for the study of its potential therapeutic targets.

Treating neurogenic detrusor overactivity in order to manage autonomic dysreflexia - A systematic review.

INTRODUCTION: Autonomic dysreflexia (AD) is a severe and potentially life-threatening complication of a spinal cord injury (SCI), particularly in patients with lesions at or above the sixth thoracic level. Neurogenic detrusor overactivity (NDO) is one of the main triggering factors. The impact of NDO treatment on AD remains insufficiently clarified. METHODS: We conducted a systematic review of the literature in PubMed and Cochrane Database between January 1990 and May 2025. Eligible studies included patients with SCI and AD undergoing treatment for NDO, including antimuscarinics, botulinum toxin (BTX) or augmentation cystoplasty. The primary outcome was the assessment of systolic blood pressure (SBP) parameters in patients undergoing cystomanometry. RESULTS: Of the thirteen eligible studies, only five were included. No study evaluated augmentation cystoplasty. One study (12 patients) evaluating fesoterodine and four studies (95 patients) evaluating BTX injection demonstrated improved urodynamic parameters and a decrease in severity of AD during urodynamic studies and in daily life. Improvements in AD-HR-QoL and I-QoL scores were also demonstrated. DISCUSSION: Controlling NDO with fesoterodine or BTX injection reduces the prevalence and severity of AD, likely by limiting abnormal C-fiber recruitment and reducing neurogenic inflammation. BTX additionally modulates TRPV1-expressing afferents, which further reduces AD risk. Although hypertensive peaks improve, submaximal parameters remain unchanged, highlighting the need for additional complementary strategies. CONCLUSION: The use of BTX and fesoterodine for NDO treatment effectively reduces AD episodes in patients with SCI. Further long-term studies are needed to confirm the cardiovascular benefits and inform future therapeutic strategies.

Comparative safety and operative efficiency of surgical approaches for open reduction and internal fixation of mandibular condylar fractures: a systematic review and network meta-analysis.

BACKGROUND: The optimal surgical approach for mandibular condyle fractures remains controversial, particularly regarding the trade-off between facial nerve safety and surgical efficiency. METHODS: Our systematic review and frequentist NMA analyzed studies evaluating open reduction and internal fixation (ORIF) for mandibular condyle fractures. The primary safety outcome was transient or persistent (&#x2265;6 months) facial nerve weakness. The efficiency outcome was operative exposure time. Surgical approaches were categorized, and random-effects NMAs estimated odds ratios (ORs) and mean differences (MDs). Treatments were ranked using P-scores, and clustered rankings explored safety-efficiency relationships. RESULTS: Overall, 121 studies (n&#x202f;=&#x202f;6659 patients) were included. For facial nerve safety, endoscope-assisted (EA), preauricular transmasseteric anteroparotid (PATMA), and high submandibular (HSMA) approaches ranked highest, while the retromandibular transparotid (RMTA) approach carried a higher risk. Analyses restricted to persistent weakness yielded consistent results. For exposure time, submandibular (SM), HSMA, and retromandibular transmasseteric anteroparotid (RMTMA) approaches were most efficient. Clustered ranking analysis identified HSMA and RMTMA as achieving the best overall balance between safety and efficiency. Subgroup analyses confirmed the overall hierarchy, though evidence for high-level and intracapsular fractures remains limited. CONCLUSIONS: HSMA and RMTMA offer an optimal compromise between safety and efficiency for extracapsular condylar fractures, while EA may minimize nerve injury risk where technical expertise allows. High-quality comparative trials - particularly for intracapsular fractures - are warranted.

The effect of hip abductor or external rotator strength on dynamic knee valgus in healthy subjects-a systematic review with partial meta-analysis.

BACKGROUND: Weak hip abductors and external rotators (ER) have long been suggested to cause increased dynamic knee valgus. Patients are often prescribed strengthening of these muscles with the expectation that it will reduce their risk of pain and injury. The validity of this claim remains unclear. METHOD: We conducted a systematic review and partial meta-analysis assessing the association between hip strength and knee valgus in healthy subjects. An online search was conducted in May 2026. Databases included Medline, EMBASE, CINAHL and Google Scholar. INCLUSION CRITERIA: English language, asymptomatic subjects, dynamometric hip strength, single or multi-camera kinematic analysis, and statistical tests of difference or correlations between hip abductor or ER strength and dynamic valgus. Data were extracted concerning study design, subject characteristics, relevant outcome measures and statistics. RESULTS: 22 papers qualified for inclusion. Hip abductor correlations: 12 papers found no significant correlation, 2 supported the hypothesis and 2 found evidence contrary. Hip ER correlations: 8 papers found no significant correlation, 2 supported the hypothesis and 2 were contrary. Group differences for hip abduction strength: 3 papers found no difference, 2 found significant differences in support of the hypothesis, 1 found significant difference to contrary. Group differences for ER strength: 1 paper found no significant difference. None of the partial meta-analyses achieved statistical significance. CONCLUSION: Weakness in hip abductors or external rotators may not result in increased dynamic knee valgus in healthy subjects. While continued research may further illuminate our understanding, we discuss alternative explanations.

Perioperative analgesic efficacy of ultrasound-guided erector spinae plane block and posterior transversus abdominis plane block in paediatric patients undergoing open pyeloplasty: A prospective randomised trial.

PURPOSE: Open pyeloplasty in the paediatric population involves extensive tissue dissection and manipulation, resulting in significant postoperative pain. Ultrasound-guided fascial plane blocks have emerged as an important component of multimodal analgesia in abdominal surgeries. This study compared the analgesic efficacy of ultrasound-guided Erector spinae plane block (ESP) and posterior transversus abdominis plane (pTAP) block in children undergoing open pyeloplasty. METHODS: It is a prospective, randomised, double-blind study conducted at a single paediatric centre in a tertiary care hospital in Asia from January 2022 to June 2023. 40 ASA I-II children were randomised to receive either the ESP block (Group E) or the pTAP block (Group T). Both groups received 0.4 ml/kg, 0.2% ropivacaine with 1 mcg/kg dexmedetomidine. Children with an allergy to local anaesthetics, cardiac, renal or hepatic dysfunction and local site infection were excluded. The primary outcome was cumulative 24 h postoperative acetaminophen consumption. Secondary outcomes included the effects on intraoperative hemodynamics, perioperative opioid consumption, FLACC and Watcha scores, time to first rescue analgesia, and any block-related complications. RESULTS: Weight-normalised 24 h postoperative acetaminophen consumption was significantly lower in the ESP group (13.5 &#xb1; 4.7 mg/kg) compared to the pTAP group (25.4 &#xb1; 8.3 mg/kg), with a mean difference of -12 mg/kg (p < 0.001, 95%CI -16 to -7.6). The median time to first rescue analgesia was significantly longer in the ESP group (18 h [95% CI, 18-24]) than in the TAP group (9 h [95% CI, 6-12]), p < 0.001. Although FLACC scores were significantly lower in the ESP group at 30 min and 12 h postoperatively, the overall longitudinal analysis using a linear mixed-effects model showed no significant difference in the trend of FLACC scores over time between the two groups. There were no block-related complications. CONCLUSION: Ultrasound-guided ESPB provides better, longer-lasting analgesia than posterior TAP block in children undergoing open pyeloplasty. Hence, it may serve as an effective component of multimodal pain management in paediatric open pyeloplasty.

Silent crises in the COVID-19 pandemic shadow: a six-year medico-legal review of non-lethal intimate partner violence in Morocco.

Intimate partner violence (IPV) is a major global public health concern and one of the most prevalent forms of gender-based violence, with significant consequences. This study analyzes non-lethal IPV cases reported to a medico-legal unit of Casablanca between 2018 and 2023. Data from 4,784 female victims were reviewed, focusing on socio-demographics, violence types, perpetrator relationships, and judicial involvement across the pre-COVID, peak COVID-19, and post-COVID periods. Married women represented 59.2% of victims. Physical violence predominated (83.1%), while sexual violence was underreported (14.7%). The year 2020 marked a sharp increase in reported non-lethal IPV cases (n&#x2009;=&#x2009;1,005), correlating with pandemic confinement. Among married women, judicial requisition (legal request for forensic examination) and medico-legal certification (medical documentation for judicial use) rates were high (81.5% and 81.0%, respectively). Post-pandemic years declined moderately but remained above pre-COVID levels. International comparison confirmed a global rise in IPV during COVID-19, with Morocco displaying comparatively higher rates of medico-legal documentation and judicial involvement. IPV in Morocco is entrenched and intensified by COVID-19. While the medico-legal system is robust in documentation, the system must evolve by integrating systematic psychological assessment into medico-legal evaluations, standardizing certification and referral protocols, and strengthening coordination between medico-legal, health, and social support services to improve victim protection.

Outcome of conservative management of small renal stones in prepubertal children.

INTRODUCTION: Renal stones are relatively uncommon in the pediatric population. This study aimed to evaluate the utility of conservative management of small renal stones in prepubertal children. PATIENTS AND METHODS: A retrospective chart review was conducted for children (&#x2264;12 years old) with small renal stones (3-10 mm) from 2016 to 2023 who underwent conservative management. Management included periodic renal ultrasonography, every 6 months, in addition to good hydration. Stones were confirmed by two consecutive ultrasounds. We recorded the patient's demographics and ultrasound findings (stone side, size, laterality, location, number, and associated hydronephrosis). Surgical intervention was indicated if recurrent loin pain, recurrent UTI, or worsening hydronephrosis (obstructing stone). Nephrolithiasis was considered resolved if stones were not visualized on 2 consecutive ultrasounds. Moreover, we evaluated conservative management outcomes for those presented during infancy (<12 months) versus later. RESULTS: We included 52 patients (65renal units) who presented at a median age of 46.1months (5.3-155.1). Seventy-five percent of patients had incidental renal stones. The median stone size was 4 mm (3-10). Forty-six percent of stones were in the lower calyx. The majority (70.8 %) had no hydronephrosis at presentation. During a median follow-up of 39months, 15patients with 17units (26.2 %) were documented stone-free. Ten patients (19.2 %) had symptomatic stone events, all measured &#x2265;4 mm. Of them, 6 patients (6 units) underwent surgical interventions, and 4 patients (4 units) experienced complications. A ROC curve analysis identified a stone size cutoff of 4 mm (sensitivity 100 % and 29 % specificity) that could be associated with symptomatic stone events. Using a multivariate Cox regression model, stone size was the only significantly associated factor with subsequent surgical intervention (p = 0.007). 19 % (10patients,12units) presented during infancy. Notably, the incidence of stone-free rate was significantly higher during infancy compared to older children (58.3 % vs 18.9 %,respectively). DISCUSSION: During a 39-month follow-up, 4 patients developed complications (2recurrent pain and 2 experienced UTI), supporting the safety of conservative management of small renal stones. This study is limited due to its retrospective design and the reliance on ultrasound as the main imaging method. To minimize that, all ultrasound images were carefully reviewed by two pediatric urologists. Moreover, renal stones were confirmed using strict criteria, which required detection in two consecutive ultrasounds. CONCLUSION: Although 26.2 % of units had spontaneously resolved nephrolithiasis, surgical intervention was only required in 11.5%of patients, all of whom had renal stones&#x2265;4 mm. Infants had higher spontaneous resolutions without complications, suggesting that conservative management may be especially effective in this subgroup.

Mechanistic Insights Into the Association Between Gut Microbiota Diversity and Atherosclerosis, Acute Coronary Syndrome, and Peripheral Arterial Disease Progression.

BACKGROUND: The gut microbiome has emerged as a potential contributor to cardiovascular diseases (CVDs), including atherosclerosis, acute coronary syndrome (ACS), and peripheral arterial disease (PAD). While observational studies link dysbiosis to CVD, causal relationships remain uncertain. METHODS: This narrative review synthesizes evidence from human observational studies, clinical interventions, and experimental models to distinguish association from mechanistic plausibility and clinical causality. Literature was searched through July 2026 in PubMed/MEDLINE, Web of Science, and Scopus. RESULTS: Microbial metabolites-including trimethylamine N-oxide (TMAO), short-chain fatty acids (SCFAs), bile acids, and lipopolysaccharide (LPS)-modulate endothelial function, immune cell programming, platelet activity, and plaque stability through receptor-mediated signaling and epigenetic regulation. SCFAs demonstrate potentially protective effects via GPCR and HDAC pathways, while TMAO is associated with atherothrombotic risk. However, much mechanistic evidence derives from preclinical studies. Heterogeneity from diet, geography, host characteristics, renal function, and medications substantially influences microbiota-CVD associations. CONCLUSION: The gut-vascular connection is biologically plausible, but definitive clinical causality remains unproven. Microbiome-directed therapies (dietary modulation, pre/pro/synbiotics, targeted metabolite inhibition) are investigational. Prospective, standardized, adequately powered human studies with clinically meaningful outcomes are essential before routine cardiovascular application.

Weight-bearing locomotion mitigates the progression of post-traumatic knee osteoarthritis in male rodents: A systematic review and meta-analysis.

OBJECTIVE: Although knee post-traumatic osteoarthritis (PTOA) has been associated with altered loading, how weight-bearing (WB) activities should be modulated post-injury to preserve knee health remains unknown. This systematic review and meta-analysis examined the effects of WB locomotion on knee PTOA in rodents to provide insight into potential clinical implications. DESIGN: Studies published in PubMed, Cochrane Library, Embase, and CINAHL through 02/2025 and meeting the following criteria were included: 1) rodents with knee PTOA, 2) compared locomotor exercises (treadmill/wheel) to no exercise, 3) outcome measures of PTOA (OARSI/Mankin OA scores, bone quality, osteophyte condition, cartilage quality/morphology). If significant heterogeneity across studies was observed, locomotion speed, time/number of intervention sessions, frequency and duration of intervention, exercise initiation, follow-up time, animal species, PTOA model were analyzed as potential moderator variables that may influence findings. RESULTS: Twenty-two studies met the criteria, resulting in a total of 156 effect sizes (ESs) for meta-analysis (all males). A positive ES denotes less PTOA. Based on the CAMARADES checklist, 5 studies were ranked low risk of bias and 14 studies were ranked moderate risk of bias. Locomotion significantly reduced PTOA severity evaluated using OARSI/Mankin scores (ES=0.927, 95% CI: [0.590, 1.264]) and improved bone quality (ES=0.379, 95% CI: [-0.023, 0.780]) with substantial heterogeneity across studies. Follow-up analyses indicated that greater ESs for reducing OA scores were associated with a shorter duration of each training session, more training sessions, longer intervention duration, and longer follow-up time (all P&#x2264;0.004). Greater ESs for improving bone quality were associated with a longer follow-up time and later exercise initiation post-injury (both P&#x2264;0.014). Locomotion resulted in small to moderate but non-significant positive effects for isolated measures assessing osteophyte condition (ES=0.379, 95% CI: [-0.023, 0.780]), cartilage quality (ES=0.430, 95% CI: [-0.034, 0.893]), and cartilage morphology (ES=0.464, 95% CI: [-0.006, 0.934]). CONCLUSION: WB locomotion reduced the overall degree of knee PTOA in male rodents. Composite knee OA scores may be more responsive to exercise interventions than isolated cartilage/osteophyte measures. The benefits of locomotion may be more prominent with a longer follow-up time or with exercise protocols consisting of shorter but more individual sessions and longer overall intervention durations.
