Treatment of Established Groin Lymphatic Complications After Arterial Surgery: A Systematic Review.

BACKGROUND: To systematically review the effectiveness and safety of interventions for established groin lymphatic complications after arterial vascular surgery. METHODS: PubMed, Embase, and Cochrane CENTRAL were searched from inception to May 28, 2025. This review was registered in PROSPERO (CRD420251061708) and conducted according to PRISMA, PRISMA-S, and Synthesis Without Meta-analysis (SWiM) guidance. Eligible studies included adults with established groin lymphorrhea/lymphocutaneous fistula or seroma/lymphocele after arterial exposure in the common femoral or iliofemoral region. Prophylactic studies were excluded. Two reviewers independently screened studies and assessed full texts. Prespecified outcomes were resolution, time to resolution, length of stay, surgical site infection, wound complications, reintervention, and recurrence. Owing to substantial heterogeneity, meta-analysis was not performed. RESULTS: Eighteen retrospective single-center studies were included; no randomized trials were identified. Reported strategy-family totals were operative control (n = 240, including 55 dye-assisted cases), intranodal lymphangiography with glue embolization (n = 39), intracavitary or chemical instillation (n = 52), negative-pressure wound therapy (n = 20), radiotherapy (n = 206), and drainage or aspiration alone (n = 7). One additional cohort compared nonsurgical with surgical management. Definitions, follow-up windows, and statistical reporting were inconsistent, and arm-level denominators were frequently incomplete. Risk of bias was serious to critical across the evidence base, mainly because of retrospective design, confounding by indication, treatment-selection bias, inconsistent outcome definitions, and incomplete reporting. Using GRADE principles, certainty of evidence was very low across strategies and phenotypes. Across study arms, conduit-directed approaches for external leak and cavity-directed approaches for encapsulated collections often achieved control, but valid comparative inference was not possible. CONCLUSION: Evidence is limited to small retrospective series with heterogeneous definitions, serious to critical risk of bias, and very low certainty. Reliable comparisons between interventions cannot currently be made. Standardized phenotype-specific definitions and outcome reporting are needed to support prospective studies and future trials.

Feasibility and acceptability of skills training in affective recovery (STAR) video and TextSTAR text message program for recent sexual assault survivors.

Background: Sexual assault (SA) affects more than 50% of women in the United States and is associated with elevated risk for impairing posttraumatic stress symptoms and substance, particularly opioid, misuse. Intervening following SA exposure could attenuate these risks.Objective: This study examined the acceptability and feasibility of a 17-minute video, Skills Training in Affective Recovery (STAR) and a 21-day text message program (TextSTAR), that were delivered in the acute post-SA period to prevent the onset or escalation of posttraumatic stress symptoms and substance misuse. The interventions provide psychoeducation about trauma, strategies to reduce fear and avoidance, suggestions to increase social support, and coping strategies for substance use.Method: Participants were 50 women age 18 or older who presented for a Sexual Assault Medical Forensic Exam (SAMFE) within seven days of a SA. Using a Sequential Multiple Assignment Randomized Controlled Trial (SMART) design, participants were randomized to receive the STAR video (n = 25) or no video (n = 25) at the SAMFE. Those who received the video answered questions about video acceptability immediately after viewing the video. At 1-week post-SAMFE, participants completed online questionnaires about substance use and posttraumatic stress; those above threshold on acute stress or opioid use (n = 36) were randomized to TextSTAR (n = 18) or no-text program (n = 18). Participants completed weekly online surveys 2-4 weeks post-SAMFE about symptoms and text program acceptability.Results: Participants found STAR and TextSTAR at least moderately acceptable; 80% who received STAR found it extremely acceptable while 60-90% (depending on timepoint) who received TextSTAR found it at least moderately acceptable. Our ability to enroll 50 participants and retain 94% at 1 week and 90% at 4 weeks suggests the intervention trial is feasible.Conclusions: STAR and TextSTAR are acceptable and feasible brief interventions for recent sexual assault survivors.Trial registration: ClinicalTrials.gov identifier: NCT06456190.

The relationship between food intake and outdoor temperature in a longitudinal study: a public health perspective in the context of global warming.

BACKGROUND: Climate change affects human health and nutrition. Rising temperatures may significantly impact diets, but research on their influence on dietary habits in large populations remains limited. OBJECTIVES: We aimed to study the link between outdoor temperature and energy-adjusted food consumption across profiles in a longitudinal study. METHODS: This study included 100,851 participants from the NutriNet-Santé study (2009-2023) with 1,716,046 24-h dietary records linked to daily maximum outdoor temperature at the residence, from the nearest Météo-France station. Associations were analyzed using linear mixed models with interactions tested for sex and 6 socioeconomic profiles (employees, privileged, intermediate, young, disadvantaged, and retirees) derived from clustering. RESULTS: Across all subgroups, higher outdoor temperature was associated with higher consumption of fruits, vegetables, processed meats, sweet products, water, alcoholic beverages, and sugar-sweetened beverages, whereas consumption of red meat, pulses, and dairy products decreased. From 25°C to 35°C, the increase in alcohol consumption with temperature was more pronounced in males {150 g/d [95% confidence interval (CI): 147 g/d, 153 g/d] to 166 g/d [95% CI: 162 g/d, 171 g/d], +11%} than in females [101 g/d (95% CI: 98 g/d, 103 g/d) to 107 g/d (95% CI: 104 g/d, 109 g/d), +6%]. Across socioeconomic profiles, changes shared similar directions, but some trends were more marked, notably for alcoholic beverages among employees (95% CI: 114 g/d, 130 g/d; +14%) and sugar-sweetened beverages in young (95% CI: 56 g/d, 72 g/d; +29%). Consumption of fruits increased more modestly in the young (95% CI: 227 g/d, 248 g/d; +9%) than in employees (95% CI: 194 g/d, 227 g/d; +17%). These changes, although variable in magnitude, were not accompanied by substantial modifications in energy intake or overall diet quality scores. CONCLUSIONS: These results emphasize the importance of targeted prevention messages when temperatures exceed 25°C, especially concerning alcoholic and sugar-sweetened beverages, and offer insight into potential long-term food consumption patterns (beyond seasonal changes) in the context of global warming.

Comparison of Traditional Chinese Exercise and Equipment-Based Exercise on Glycaemic Control and Vitamin D Levels in Middle-Aged and Elderly Patients With Prediabetes: A Randomised Controlled Trial.

BACKGROUND: Prediabetes is a critical window for preventing progression to type 2 diabetes mellitus (T2DM). Both vitamin D deficiency and physical inactivity are associated with impaired glucose metabolism. This study compared the effects of Traditional Chinese Exercise (TCE) and Kuanle Equipment Exercise (KEE) on glycaemic measures, lipid profiles, body composition and serum 25-hydroxyvitamin D3 [25(OH)D3] in middle-aged and elderly adults with prediabetes. METHODS: We conducted a 12-week, single-centre, randomised controlled trial involving 62 participants with prediabetes (mean age 55.2 ± 8.4 years; 88.7% female). Participants were randomly assigned to control (usual care, n = 21), TCE (n = 20), or KEE (n = 21). Primary outcomes included fasting plasma glucose (FPG), 2-h OGTT glucose, glycated haemoglobin (HbA1c) and serum 25(OH)D3. Secondary outcomes comprised triglycerides, total cholesterol, LDL-C, HDL-C and body composition. RESULTS: At baseline, mean serum 25(OH)D3 was 21.53 ± 3.90 nmol/L. At 12 weeks, both TCE and KEE improved FPG, 2-h OGTT glucose, HbA1c and 25(OH)D3 versus control (all p ≤ 0.001). Relative changes in FPG were -9.4% (TCE) and -15.2% (KEE) versus -1.5% (control); corresponding changes were -14.6% and -21.2% for 2-h OGTT glucose, -6.7% and -12.9% for HbA1c, and +60.6% and +81.9% for 25(OH)D3. Direct TCE-KEE comparisons were not significant (all p > 0.05). In an exploratory analysis, change in 25(OH)D3 was inversely associated with change in 2-h OGTT glucose (partial r = -0.358, p = 0.006), but not with FPG, HbA1c, or triglycerides. CONCLUSIONS: Both TCE and KEE improved glycaemic outcomes and increased serum 25(OH)D3 compared with usual care in middle-aged and elderly adults with prediabetes. Although KEE produced numerically larger estimates, direct between-group comparisons were not significant, and the superiority of KEE over TCE was not established. These vitamin D findings require confirmation in trials that quantify sunlight exposure and dietary vitamin D intake.

Microbial allies in a cotton pest: A descriptive account of associated microbiota dynamics in Dysdercus cingulatus across development.

BACKGROUND: Hemipteran insects harbour several symbiotic partners, mainly bacteria, which play pivotal roles for hosts like dietary provision, support overall physiology, xenobiotic degradation and manipulate/regulate behaviour. Most of these symbionts usually reside and operate from the digestive tracts of the animals. Cotton is one of the major cash crops in India and Dysdercus cingulatus (D. cingulatus) though a secondary pest, is causing significant destruction of cotton bolls, poor lint quality and reduce oil content of seeds. Premature opening of cotton bolls often leads to bacterial and fungal infections, thus resulting in extensive economic loss worldwide. D. cingulatus is a hemimetabolous insect that comprises of developmental stages like egg, nymph (5 instar stages), and adult. The present work explored the ontogeny specific diversity in the associated microbiota and predicted their probable functional inputs in D. cingulatus. RESULTS: The data obtained using 16S rRNA gene sequencing (NovaSeq 6000) revealed presence of members of Proteobacteria (65.83%), Firmicutes (24%), Actinobacteria (10%) phyla throughout the ontogeny of D. cingulatus. Highest alpha diversity of these symbiotic bacteria was recorded in the third instar nymphs in contrast to rest of the developmental stages. Among all the observed genera, Stenotrophomonas, Hungatella and Glutamicibacter were predominant from egg to adult stages. MicFunPred, a tool used for predicting the probable functional inputs of these symbionts, hinted at their probable stage specific contribution in crucial biochemical pathways such as polyketide biosynthesis, ascorbate/aldarate metabolism, pentose phosphate and glyoxylate cycles, steroid hormone and peptidoglycan biosynthesis, and glycolysis/pyruvate metabolism. CONCLUSIONS: The primary investigations on the ontogenetic composition and diversity of associated microbiota, suggest dynamic shifts in D. cingulatus, concurrent with their probable functions/roles in the host development and metabolism. To the best of our knowledge, this is the first report on symbiotic microbiota variation across the developmental stages of D. cingulatus that provides preliminary descriptive observations that may guide future functional and experimental investigations into microbiota-based pest management.

The Impact of Chatbot Type and Normative Messaging on Chatbot Usage Intention Based on the Health Technology Acceptance Model: Randomized Controlled Trial.

BACKGROUND: Digital health tools, such as health chatbots, may improve access to scalable health support, but adoption remains inconsistent. Existing models do not fully integrate technology acceptance factors with health motivation factors relevant to digital health use. OBJECTIVE: This study proposed and tested the health technology acceptance model and examined whether normative message framing and chatbot type were associated with health motivation, technology acceptance, and intention to use a health chatbot. METHODS: In October 2025, we conducted a 4 &#xd7; 2 between-participants online experiment with 1000 US adults recruited from a nationally representative YouGov panel. Participants were randomized to 1 of 8 conditions varying norm message type (self-oriented, peer-oriented, expert-oriented, or family-oriented) and chatbot type (AI-powered or rule-based) in a cancer prevention and genetic risk information scenario. Outcomes included descriptive norms, injunctive norms, perceived susceptibility, perceived severity, perceived benefits, self-efficacy, perceived ease of use, trust, privacy concerns, and usage intention. Data were analyzed using a multivariate ANOVA with Bonferroni-adjusted post hoc tests and multiple linear regression. RESULTS: Peer-oriented and family-oriented messages produced higher usage intention than expert-oriented messages, and peer-oriented messages also increased descriptive norms, injunctive norms, self-efficacy, and trust. AI-powered chatbots were associated with higher usage intention (P=.02) and greater trust (P=.008) than rule-based chatbots. In regression analyses, the model explained 50.8% of the variance in usage intention. Usage intention was positively associated with descriptive norms (&#x3b2;=0.087; P=.003), injunctive norms (&#x3b2;=0.078; P=.009), perceived susceptibility (&#x3b2;=0.051; P=.03), perceived benefits (&#x3b2;=0.253; P<.001), and trust (&#x3b2;=0.33; P<.001), and negatively associated with perceived severity (&#x3b2;=-0.047; P=.049) and privacy concerns (&#x3b2;=-0.11; P<.001). Perceived ease of use and self-efficacy were not significant predictors. CONCLUSIONS: The health technology acceptance model was a useful framework for explaining the intention to use a health chatbot by combining technology acceptance and health motivation constructs. Both social design features and chatbot design features shaped adoption-related beliefs, with peer-oriented and family-oriented framing and AI-powered chatbots showing particular promise. Trust and privacy concerns remained central determinants of intended use.

Neoplasms in prune belly syndrome: A novel case of early-onset metastatic bladder carcinoma and systematic review of reported tumors.

PURPOSE: Prune Belly Syndrome (PBS) is a rare congenital malformation complex characterized by cryptorchidism, urinary tract abnormalities and deficiency of the abdominal wall musculature. Although advances in neonatal and reconstructive care have substantially improved survival, the long-term risk of malignancy in this population remains poorly defined. We report a novel case of early-onset metastatic bladder carcinoma in a patient with PBS and perform a systematic review of all tumors described in association with the syndrome. METHODS: A systematic literature review was performed according to PRISMA guidelines and registered in PROSPERO (CRD420251072086). Databases searched through April 2025 included PubMed, Embase, Web of Science, ClinicalTrials.gov, Cochrane, and SciELO. Reported tumor cases in PBS patients were identified and classified as either PBS-associated or not. We additionally describe a new case of invasive bladder carcinoma. RESULTS: Seventeen studies comprising 20 patients met inclusion criteria. Tumors directly related to the genitourinary tract accounted for half of the cases. Bladder carcinoma was the most frequent neoplasm (35%), followed by hepatoblastoma (25%). Bladder tumors occurred at markedly younger ages and often presented as advanced diseases. Our index case involved a 33-year-old man with PBS who developed metastatic muscle-invasive urothelial carcinoma and died shortly after diagnosis. DISCUSSION: Improved survival in PBS has led to recognition of new late complications, including malignancy. Tumorigenesis may be influenced by chronic urinary stasis, infection, catheterization, cryptorchidism, and underlying genitourinary developmental abnormalities. These findings should be interpreted as hypothesis-generating given the limited number of reported cases. CONCLUSION: Although uncommon, malignancies in PBS may occur earlier and behave more aggressively than in the general population. Given the current level of evidence, careful long-term follow-up with clinical awareness is warranted, rather than routine invasive screening for all patients.

Prothrombin complex concentrate (PCC) vs. non-PCC strategies for warfarin reversal in left ventricular assist device recipients: A systematic review and meta-analysis.

BACKGROUND: Left ventricular assist devices (LVADs) prolong survival in end-stage heart failure, and warfarin thromboprophylaxis is recommended to prevent device thrombosis and thromboembolic complications. When bleeding occurs or emergency surgery is required, rapid anticoagulation reversal is critical. Prothrombin complex concentrate (PCC) provides rapid reversal; however, its risk-benefit profile in LVAD recipients remains unclear. We conducted a systematic review and meta-analysis comparing PCC with non-PCC strategies for warfarin reversal in LVAD recipients. METHODS: MEDLINE, Embase, and Scopus were searched through June 2025 for studies of PCC versus non-PCC strategies for warfarin reversal in LVAD recipients. Two reviewers independently extracted data. Random-effects models were used to pool arm-level estimates and to pool head-to-head comparisons using mean differences or risk ratios (RRs). RESULTS: Eighteen studies involving 779 patients were included. Arm-level pooled estimates for PCC versus non-PCC comparators were 24.0% versus 15.8% for mortality, 16.5% versus 12.1% for thrombotic events, and 3.1 versus 5.7 for FFP units. Arm-level time to INR correction was longer with PCC overall (16.5 versus 13.6&#xa0;h), driven by one elective cohort, but faster within the ICH subgroup (6.0 versus 13.7&#xa0;h). In head-to-head comparisons, PCC achieved faster INR correction than non-PCC comparators (mean difference&#xa0;-&#xa0;7.6&#xa0;h; p&#xa0;=&#xa0;0.001) and required fewer FFP units (-2.6&#xa0;units; p&#xa0;=&#xa0;0.019), with no significant difference in all-cause mortality (RR 1.14; p&#xa0;=&#xa0;0.490) or thrombotic events (RR 1.43; p&#xa0;=&#xa0;0.176). CONCLUSIONS: In head-to-head studies, PCC was associated with faster INR correction and lower FFP requirements than non-PCC strategies, whereas mortality and thrombotic events did not differ significantly. Given the observational evidence, wide confidence intervals, and heterogeneity, equivalent safety cannot be established, and prospective studies are needed to define the relative safety and effectiveness of the two approaches. IMPLICATIONS FOR CLINICAL PRACTICE: PCC-based strategies may be considered for urgent warfarin reversal in LVAD recipients, particularly when rapid INR reduction or avoidance of large-volume plasma transfusion is clinically important. Treatment decisions should account for the indication, bleeding severity, and underlying thrombotic risk. TRIAL REGISTRATION: CRD42024573925.

Risk Factors and Predictive Model for Postoperative High Myopia in Children Undergoing Congenital Cataract Surgery With Intraocular Lens Implantation.

PURPOSE: To identify risk factors associated with the development of high myopia following congenital cataract surgery and to establish a robust predictive model. DESIGN: Retrospective clinical cohort study. SUBJECTS: This retrospective study included 106 pediatric patients who underwent congenital cataract surgery with primary IOL implantation (mean follow-up 8.19 years). The model was externally validated in an independent cohort of 72 patients with a mean follow-up of 7.83 years. METHODS: Preoperative and postoperative ocular biometric parameters were collected. Risk factors for postoperative high myopia were analyzed using Cox proportional hazards regression, which served as the basis for model construction. The predictive performance of the model was rigorously evaluated for discrimination and calibration. Discriminative ability was quantified using Harrell's C-index and the area under the receiver operating characteristic curve (AUC). Model calibration was assessed via calibration plots by comparing predicted probabilities with actual observed outcomes. Internal validation was performed using a bootstrapping method (500 iterations) to ensure model stability and adjust for potential overfitting. RESULTS: An initial postoperative refraction of <+0.75D, and a higher IOL Power to Axial length Ratio (IOL/AL ratio) were identified as significant risk factors for the development of postoperative high myopia. Shorter preoperative axial length was associated with a greater magnitude of postoperative myopic shift. The predictive model demonstrated robust performance, achieving a C-index of 0.711 (internal validation C-index: 0.713). The area under the receiver operating characteristic curve (AUC) values for predicting high myopia at 5 and 10 years were 0.858 and 0.745, respectively. Furthermore, calibration curves demonstrated excellent agreement between the predicted and observed outcomes throughout the follow-up period. In external validation, the model achieved a C-index of 0.825, 5-year AUC of 0.833, and 10-year AUC of 0.713. CONCLUSIONS: Our analysis established that initial postoperative refraction <+0.75D, and an elevated IOL/AL ratio are key determinants of high myopia risk following surgery. Shorter preoperative axial length was associated with a greater magnitude of postoperative myopic shift. This predictive framework provides clinicians with a practical tool to optimize preoperative IOL selection and identify high-risk infants who require vigilant myopia prevention and balanced amblyopia management.

Biologic-biologic and biologic-JAK inhibitor combination therapy in refractory systemic autoinflammatory diseases.

OBJECTIVES: Systemic autoinflammatory diseases (SAIDs) arise from genetic defects in innate immunity, leading to dysregulated activation of inflammatory pathways, including interleukin (IL)-1, IL-6, TNF, and JAK/STAT. Clinical manifestations range from recurrent fever to severe complications such as encephalitis and AA amyloidosis. Management aims to control inflammation using immunosuppressive agents and targeted monotherapies (biologics or JAK inhibitors). Advanced combination therapy (ACT), defined as the use of biologics and/or JAK inhibitors in combination, has emerged as a strategy for refractory disease. METHODS: In this observational retrospective longitudinal cohort study, patients with SAIDs treated with ACT were included. Demographic, clinical, treatment, and safety data were collected. Treatment response was assessed using a composite outcome incorporating corticosteroid dose, C-reactive protein (CRP), and clinical improvement and categorized as non-response, partial response, or complete response. RESULTS: Thirty-eight patients (median age 30 years [range 4-76]) were included. The most common indications for ACT were pyogenic arthritis, pyoderma gangrenosum and acne (PAPA), mevalonate kinase deficiency (MKD), and undifferentiated SAIDs. Most patients had disease-related complications and were dependent on glucocorticoids and/or opioids to control inflammation and pain, respectively. Following multiple ACT trials, complete response was observed in 21 patients (55.3%), partial response in 12 (31.6%), and no response in 5 (13.1%). Overall, 65 ACT regimens were administered, most commonly combining IL-1 and TNF inhibitors. Thirty-nine regimens were discontinued because of lack of efficacy, secondary loss of response, or adverse events. At the final follow-up, 26 patients (68%) remained on ACT, with a median treatment duration of 60 months (range, 11-186). CONCLUSIONS: ACT offers significant clinical benefits for patients with difficult-to-treat SAIDs, though challenges such as secondary loss of efficacy and infection risks remain.

Therapeutic-drug-monitoring-based ATG Targeted Dosing Strategy in Unmanipulated Haploidentical Haematopoietic Stem Cell Transplantation: a randomized, multicenter, phase 3 clinical trial.

Anti-thymocyte globulin (ATG) has been a standard prophylaxis for graft-versus-host disease (GVHD). However, the pharmacokinetics of ATG in vivo vary significantly, and weight-based fixed dosing may not optimize efficacy while minimizing toxicity. We investigated the clinical results of a therapeutic-drug-monitoring (TDM)-based, dose-optimized ATG strategy versus weight-based fixed dosing in haploidentical haematopoietic stem cell transplantation (NCT05166967). Patients were randomly assigned in a 1:1 ratio to receive a targeted dose of ATG or a fixed dose of 10&#x202f;mg/kg. The primary endpoint was the 365-day graft-versus-host disease-free and relapse-free survival (GRFS). From January 1, 2022, to January 16, 2024, 204 patients were enrolled, with 102 patients in each group. The 365-day GRFS was higher in the targeted dose group (66.7%) than in the fixed dose group (50.0%; hazard ratio [HR], 0.666; 95% confidence interval [CI], 0.4456 to 0.9954; P&#x202f;=&#x202f;0.048). The cumulative incidence of moderate to severe chronic GVHD at day 365 was significantly lower in the targeted dose group (9.8%; 95% CI, 5.0 to 16.5) compared with the fixed dose group (22.5%; 95% CI, 15.0 to 31.1; P&#x202f;=&#x202f;0.026). Fewer grade 3-5 infections were reported in the targeted dose group (44.1%) than in the fixed dose group (70.6%; P&#x202f;<&#x202f;0.001). More patients in the targeted dose group achieved optimal ATG exposure (P&#x202f;=&#x202f;0.007) and superior CD4+ T-cell reconstitution (P&#x202f;=&#x202f;0.002). These findings support the clinical utility of a TDM-based individualized ATG dosing strategy that balances efficacy and toxicity for GVHD prophylaxis in allogeneic stem cell transplantation.

Multi-omics reveals that burdock seed aglycone alleviates renal fibrosis by restoring mitochondrial oxidative phosphorylation function.

Renal fibrosis (RF), a common pathological process driving chronic kidney disease (CKD) progression to end-stage renal failure, is closely associated with oxidative phosphorylation (OXPHOS). Arctigenin (ATG), the main active component of burdock seed, exhibits anti-inflammatory and anti-fibrotic activities, but its mechanisms in RF treatment remain unclear. Here, we performed integrated transcriptomic and proteomic analyses to identify key targets and pathways of ATG in a unilateral ureteral obstruction-induced rat RF model. Multi-omics enrichment analysis revealed that NDUFS8 and NDUFS2 were the core targets of ATG, with the OXPHOS pathway as the central intersecting pathway. Our results suggest that ATG exerts anti-renal fibrosis effects by targeting the OXPHOS pathway to inhibit excessive reactive oxygen species production and oxidative stress. SIGNIFICANCE: Chronic kidney disease (CKD) continues to impose an escalating global health and socioeconomic burden, while renal fibrosis (RF), as the convergent pathological endpoint of virtually all progressive nephropathies, remains the principal determinant of irreversible renal failure and adverse clinical outcomes. Despite extensive efforts to develop antifibrotic therapies, effective clinical interventions remain elusive, largely due to the complex and multifactorial nature of RF pathogenesis. In this study, we employed an integrated multi-omics framework encompassing transcriptomics, proteomics, and metabolomics to systematically decipher the antifibrotic mechanism of arctigenin (ATG), a bioactive natural compound derived from traditional Chinese medicine. Our findings identify mitochondrial oxidative phosphorylation as the pivotal regulatory axis underlying the renoprotective effects of ATG and further establish key catalytic subunits of mitochondrial complex I as its direct molecular targets. Mechanistically, ATG not only restores complex I activity and reprograms mitochondrial energy metabolism but also preserves the intracellular stability and localization of these subunits, thereby preventing their aberrant release-mediated inflammatory activation and disrupting the self-perpetuating cycle linking metabolic dysfunction, inflammation, and fibrosis progression. Beyond revealing a previously unrecognized dual mechanism integrating metabolic and inflammatory regulation, this study provides compelling evidence that mitochondrial dysfunction is not merely a secondary consequence of tissue injury but a fundamental driver of fibrotic remodeling. Importantly, our work highlights the translational potential of natural product-based mitochondrial interventions for CKD treatment and supports a broader conceptual shift toward metabolism-centered therapeutic strategies for chronic fibrotic diseases. Given the central role of mitochondrial dysfunction across multiple organs, these findings may also have far-reaching implications for the treatment of systemic fibrosis-related disorders beyond the kidney.

Exploring the dose-response relationship between prenatal exercise and postpartum depression: A systematic review and meta-analysis of randomized controlled trials.

IMPORTANCE: Postpartum depression (PPD) is a hidden and widespread global public health crisis affecting millions of mothers and infants annually. Prenatal exercise is a potentially accessible nonpharmacological strategy for PPD prevention, but its optimal dose remains uncertain. OBJECTIVE: To explore the dose-response relationship between prenatal exercise and the incidence of PPD through meta-analysis of randomized controlled trials (RCTs). DATA SOURCES: Systematic searches were conducted in PubMed, Embase, Web of Science, and Cochrane Library using MeSH terms and keywords related to "pregnant women," "prenatal exercise," and "postpartum depression," up to June 23, 2025. STUDY SELECTION: RCTs included examined prenatal exercise interventions in pregnant women without a history of depression, with PPD incidence reported using validated depression scales (such as EPDS, CES-D). Non-RCT studies, duplicate publications, and studies with insufficient data were excluded. DATA EXTRACTION AND SYNTHESIS: Two researchers independently extracted data according to the PRISMA guidelines. A random-effects model was used to pool odds ratios (OR) and their 95% confidence intervals (CI). Linear and nonlinear dose-response models were employed to analyze and evaluate the relationship between exercise dose (measured in METs-min/week) and the incidence of PPD. MAIN OUTCOME(S) AND MEASURE(S): The primary outcome is the incidence of PPD, analyzing its relationship with prenatal exercise dose. RESULTS: Eight RCTs involving 2231 pregnant women were included. The pooled analysis showed that prenatal exercise was associated with a potential reduction in PPD incidence, although the overall effect did not reach statistical significance (OR=0.58, 95% CI [0.33, 1.02]). In dose-stratified analysis, exercise doses &#x2265;500 METs-min/week were associated with significantly lower PPD incidence (OR=0.44, 95% CI [0.24, 0.78]). Subgroup analyses suggested trends toward greater benefits among women aged &#x2265;30 years and those initiating exercise between 14 and 28 weeks of gestation; however, subgroup differences did not reach statistical significance. The linear dose-response trend did not reach statistical significance (p = 0.0533), and neither the overall spline association (p = 0.1704) nor the test for nonlinearity (p = 0.6361) was statistically significant. CONCLUSIONS AND RELEVANCE: Prenatal exercise may be associated with a lower risk of PPD, but the overall pooled effect did not reach statistical significance. Findings concerning &#x2265;500 METs-min/week and the apparent flattening of the dose-response curve should be considered exploratory and require confirmation in larger trials.

Risk factors for bleeding after endoscopic retrograde cholangiopancreatography: a systematic review and meta-analysis.

BACKGROUND AND AIMS: ERCP is associated with adverse events, including bleeding, which occurs in up to 1.3% of cases. This meta-analysis aims to identify and quantify risk factors associated with post-ERCP bleeding. METHODS: A comprehensive literature search of electronic databases was conducted from inception to January 10, 2025. Studies were eligible if they used multivariate analysis to identify predictors of post-ERCP bleeding. Risk factors reported in at least 2 studies were pooled using a random-effects model to calculate odds ratios (ORs) with 95% CIs. A further subgroup analysis was performed, including risk factors for postsphincterotomy bleeding and postendoscopic papillectomy bleeding. RESULTS: Twenty-seven studies (4 prospective and 23 retrospective studies) comprising 149,870 patients were included, of whom 1865 experienced post-ERCP bleeding. Twenty potential risk factors were analyzed. The meta-analysis identified several factors significantly associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis, including male gender (OR, 1.24; 95% CI, 1.05-1.46), anticoagulation therapy (OR, 2.75; 95% CI, 1.66-4.56), cirrhosis (OR, 2.54; 95% CI, 1.76-3.65), hemodialysis (OR, 5.82; 95% CI, 3.32-10.18), coagulopathy (OR, 11.01; 95% CI, 2.50-48.40), endoscopic sphincterotomy (EST) (OR, 3.19; 95% CI, 1.69-6.01), precut sphincterotomy (OR, 2.24; 95% CI, 1.52-3.30), and intraoperative bleeding (OR, 2.57; 95% CI, 1.80-3.66). Several factors in the pooled adjusted analysis were not found to be significantly associated with higher odds of post-ERCP bleeding, including high body mass index (BMI), nonsteroidal anti-inflammatory drug (NSAID) use, antiplatelet therapy, thrombocytopenia, common bile duct stones, cholangitis, endoscopic papillary balloon dilatation, and covered self-expandable metal stent insertion. CONCLUSIONS: This meta-analysis identified that the anticoagulation therapy, cirrhosis, hemodialysis, coagulation disorder, EST, precut sphincterotomy, and male gender are associated with increased odds of post-ERCP bleeding in the pooled adjusted analysis. Conversely, age, high BMI, cholangitis, choledocholithiasis, pancreatic duct stones, needle-knife sphincterotomy, NSAID use, and antiplatelet therapy were not significantly associated with higher odds of post-ERCP bleeding in the pooled adjusted analysis. Incorporating our results into a prediction model may assist in identifying patients at increased risk, optimizing informed consent, and guiding prevention and management strategies for post-ERCP bleeding.

Genetic mutations driving ciprofloxacin resistance in laboratory-evolved Salmonella Typhimurium.

Ciprofloxacin resistance in Salmonella Typhimurium is a significant public health concern, and the mechanisms by which the resistance evolves are poorly defined. Here, by serial passaging under antibiotic selection, we isolated ciprofloxacin-resistant S. Typhimurium mutants and subjected them to whole-genome sequencing to reveal the major mutations associated with resistance. The Low CipR mutant acquired four chromosomal mutations in ramR, icdA, lipB, and gyrA, and the High CipR mutant gained additional mutations in gyrB, yaiC, and corA. Functional characterization determined that mutations in ramR resulted in efflux pump upregulation, while disruptions in the TCA cycle caused by mutations in icdA and lipB led to metabolic alterations. These changes indirectly enhanced resistance by increasing the expression of the global regulator MarA and reducing OmpF-dependent membrane permeability. Despite the observation of the G105A substitution in GyrA, enzymatic assays confirmed the failure to support resistance to ciprofloxacin, possibly because the structural alteration remained minimal. GyrB488-489dup was associated with maintained supercoiling under ciprofloxacin and enhanced fluoroquinolone resistance, suggesting a major role in resistance evolution. Other mutations in yaiC impaired biofilm and, in corA, intracellular accumulation of magnesium, possibly stabilizing the bacterial cell envelope under antibiotic pressure. The findings provide novel explanations for the multifaceted mechanisms leading to ciprofloxacin resistance in Salmonella and suggest targets to combat antimicrobial resistance.IMPORTANCEAntibiotic resistance in Salmonella Typhimurium is an increasing public health concern, yet the genetic changes that allow bacteria to become resistant are not fully understood. In this study, we evolved ciprofloxacin-resistant Salmonella in the laboratory and identified the mutations that arise during resistance development. We found that resistance does not result from a single change but from multiple adaptations affecting drug efflux, metabolism, and the antibiotic target. Some mutations increased the activity of pumps that remove antibiotics from the cell, while others altered bacterial metabolism and reduced membrane permeability, making it harder for the drug to enter. A duplication in the DNA gyrase subunit GyrB played a particularly important role in maintaining DNA function under antibiotic stress. Together, these results reveal how diverse genetic changes cooperate to generate ciprofloxacin resistance and provide insights that may help guide strategies to combat drug-resistant Salmonella infections.

Feasibility of implementation, diagnostic accuracy, and end-user impact of an electronic health record (EHR)-based ureteral stent tracking tool in a pediatric population.

INTRODUCTION & OBJECTIVES: Ureteral stent tracking systems have reduced stent retention in adults, but their accuracy and impact in pediatrics have been minimally explored. With low event rates in children, such tools may yield high false positives, raising questions on balancing event prevention with provider burden. We aimed to evaluate the feasibility, diagnostic accuracy, and end-user impact of an Electronic Surveillance Tool for Evaluating Nephroureteral stent Tracking (eSTENT) at our institution. STUDY DESIGN: eSTENT, implemented in 1/2024, flags ureteral stents at risk for retention based on implant documentation, expected explant date, and explant documentation. Monthly reports are generated for stents missing explant documentation. We retrospectively evaluated the diagnostic performance of eSTENT from 1/2024-8/2025 at our pediatric hospital. A usability survey including a validated 1-7 implementation score (higher = easier implementation) was distributed to pediatric urologists and operating room nurses. RESULTS: Of 172 cases with ureteral stent placement, eSTENT flagged 28 events (16%) in 24 patients. Of these, 26 represented documentation gaps where explant had been appropriate. Two flags had no documentation of explant, representing near miss events that were identified. No retained stents occurred, consistent with high sensitivity and modest specificity. There were no flags in the last 6 months of the study period. Survey response rate was 100% for surgeons and 55% for nurses. Before eSTENT, stents were not routinely tracked. All surgeons and 93% of nurses reported no added burden, despite occasional misidentification of retained stents. Three surgeons found eSTENT beneficial, four were neutral, and free-text responses generally cited eSTENT's "fail safe" nature as positive. Nurses suggested improvements, including user support and integrated documentation reminders. The average implementation score among both groups was 6/7, indicating easy adoption. DISCUSSION: While the impact of stent tracking tools in adult literature has been positive, our study emphasizes the feasibility of broader adoption at a pediatric hospital. Integration of eSTENT may avoid the potentially devastating consequences of a retained stent. Prioritizing sensitivity over specificity appears acceptable for a "never event" in patient safety. Our study is limited by the retrospective nature of data collection and survey bias. CONCLUSIONS: Though no stents were retained in the study period, eSTENT appropriately flagged two cases without added burden to most end-users. Further optimization is warranted, but adoption in pediatric centers may enhance care reliability.

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.

Oil and gas well development and coccidioidomycosis risk in Kern County, CA, USA: a case-crossover study.

BACKGROUND: Coccidioidomycosis is an emerging fungal disease caused by inhaling Coccidioides spp spores. As spores reside in soil, activities that disturb soil and generate dust can aerosolise and transport the pathogen. The oil and gas industry has been extensively developed in some regions that are endemic for Coccidioides spp and has been associated with dust emissions. Although several adverse health outcomes have previously been associated with oil and gas development, its impact on coccidioidomycosis risk has not been investigated. We aimed to estimate the association between exposure to oil and gas well development (ie, wells in preproduction) and risk of coccidioidomycosis among residents living near new wells. METHODS: In this case-crossover study, we obtained information on reported coccidioidomycosis cases and oil and gas well development between 2007 and 2022 in Kern County, CA, USA. We then compared exposure to preproduction wells within 5 km of each individual's place of residence during both hazard (ie, the 49-139 days before case onset) and control periods using conditional logistic regression. FINDINGS: During the study period, 658&#x2009;108&#x2009;(72&#xb7;4%) of 909&#x2009;282 of Kern County residents lived within 5 km of at least one preproduction well, and 116&#x2009;020&#x2009;(12&#xb7;8%) lived within 5 km of 23 or more preproduction wells within a single 90-day period. We estimated that the odds of coccidiomycosis incidence were 12&#xb7;5% (95% CI 5&#xb7;8-19&#xb7;6) higher in the 90 days following exposure to at least one preproduction well within 5 km of an individual's place of residence and that the odds of infection increased by 0&#xb7;7% (0&#xb7;4-0&#xb7;9) for each additional preproduction well developed within this distance. INTERPRETATION: These findings support a previously-unrecognised association between the development of oil and gas wells and transmission of coccidioidomycosis, potentially driven by dust generation. Given the prevalence of oil and gas development in the study region, its impact on coccidioidomycosis incidence might be large. FUNDING: National Institutes of Health, National Science Foundation.
