Clinical outcomes of fusion vs excision in the treatment of painful type II accessory naviculars: A matched cohort study.

BACKGROUND: For painful Type II accessory naviculars, whether to remove or fuse them remains unclear based on the current literature. This study aimed to investigate the clinical outcomes of fusion versus excision in treating painful type II accessory naviculars. METHODS: This retrospective comparative study included and followed 54 eligible patients (from May 2017 to March 2023). After 1:1 propensity score matching (PSM), 34 patients (17 fusion versus 17 excision) were analyzed. Outcomes included Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, Tegner score, complication rates, and radiographic measurements. Receiver operating characteristic (ROC) curve analysis was performed to identify the appropriate accessory navicular size cutoff for predicting nonunion following fusion. RESULTS: The mean follow-up was 35.0&#x202f;&#xb1;&#x202f;9.9 months. The fusion and excision groups showed significant and comparable VAS and AOFAS score improvements (p&#x202f;<&#x202f;.001). The fusion group had a higher complication rate (41.2% vs. 5.9%, p&#x202f;=&#x202f;.039), primarily nonunion and persistent pain. ROC curve analysis identified 50.3&#x202f;mm&#xb2; as the cutoff for nonunion risk; sizes <&#x202f;50.3&#x202f;mm&#xb2; predicted high nonunion likelihood. CONCLUSIONS: Both fusion and excision are effective treatments for painful type II accessory naviculars, demonstrating acceptable pain and functional improvement during midterm follow-up. However, the lower complication rate along with relatively superior functional recovery favors the excision technique. For accessory naviculars smaller than 50.3&#x202f;mm2, excision may be a better choice. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Foot exercise plus education versus brief advice for the treatment of plantar heel pain (FEET Trial): a feasibility randomised controlled trial.

BACKGROUND: Despite foot muscle strengthening being a target of exercise interventions for plantar heel pain (PHP) no study has measured foot muscle outcomes, and existing research is limited by a lack of control (no treatment) comparisons. OBJECTIVES: To determine the feasibility of conducting a randomised controlled trial and investigate the acceptability and credibility of comprehensive progressive foot exercise and education compared to brief advice for PHP. DESIGN: Randomised parallel group feasibility trial. METHOD: People with PHP were randomised (1:1 concealed allocation) to receive either foot exercise plus education or brief advice for twelve weeks. Primary outcomes included willingness to enrol, recruitment rate, adherence, logbook completion, dropout rate, early withdrawal reasons, adverse events, additional treatments sought, and credibility/expectancy. RESULTS: Twenty people with PHP (16 women; age 50&#x202f;&#xb1;&#x202f;9 years; body mass index&#x202f;=&#x202f;30.7&#x202f;&#xb1;&#x202f;4.6&#x202f;kg/m2) were recruited over 15 weeks (1.3 participants per week). Primary outcomes were willingness to enrol (80%), adherence (physiotherapy sessions attended: foot exercise plus education 85%, brief advice 100%; home exercise program: 62% daily sessions completed, 72% thrice weekly sessions completed), logbook completion (foot exercise plus education 75%, brief advice 90%), dropout rate (15%), and additional treatments sought (69%). There were no intervention-related adverse events, and credibility scores were higher for foot exercise plus education. CONCLUSIONS: This study confirms feasibility and acceptability of a protocol comparing foot exercise plus education with brief advice in individuals with PHP, generating key insights to inform future trial design.

Cefoxitin versus cefotaxime as empirical treatment of spontaneous bacterial peritonitis in liver cirrhotic patients: randomized controlled clinical trial.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a severe complication of cirrhosis requiring immediate empirical antibiotic therapy. Third-generation cephalosporins are the traditional agents of choice; however, increasing clinical failure rates necessitate the evaluation of alternative antibiotics to ensure optimal therapeutic outcomes. The aim was to investigate the efficacy of cefoxitin versus cefotaxime for SBP treatment. METHODS: A randomized clinical trial was conducted on 140 cirrhotic patients with community-acquired SBP at Al-Rajhy Liver University Hospital, Assiut, Egypt. Patients were randomized to receive either cefotaxime (n&#x200a;=&#x200a;70) or cefoxitin (n&#x200a;=&#x200a;70), 2&#x2005;g every 8&#x2005;h for 5&#x2005;days. Polymorphonuclear neutrophil (PMN) counts were measured upon admission, on Day 2 and on Day 5. Clinical response rates at Days 2 and 5, development of hepatorenal syndrome, length of stay and mortality were assessed. RESULTS: According to intention-to-treat analysis, clinical response rates at Day 2 were 74.2% in the cefotaxime group and 80% in the cefoxitin group, while at Day 5, they were 71.4% and 74.3%, respectively (P&#x200a;=&#x200a;0.704). The PMN counts at Days 0, 2 and 5 showed no significant differences between the cefotaxime and cefoxitin groups (P&#x200a;=&#x200a;0.889, 0.909 and 0.360, respectively). The incidence of hepatorenal syndrome was 7.1% in the cefotaxime group compared with 8.6% in the cefoxitin group (P&#x200a;=&#x200a;0.753), and mortality was 15.7% and 12.9%, respectively (P&#x200a;=&#x200a;0.629). CONCLUSIONS: Cefoxitin showed comparable effectiveness to cefotaxime but may be utilized in selected clinically stable SBP patients.

Evaluating the need for late angiography for complete obliteration of AVMs after endovascular treatment: collaborative AVM center experience and a systematic review.

Brain arteriovenous malformations (bAVMs) can be treated curatively by endovascular embolization. However, limited data exist on late recanalization rates. We investigated the rate of late bAVM recanalization following complete endovascular obliteration, confirmed by primary control angiography.We performed a single-center retrospective cohort study on late recurrences in adult patients with bAVMs after complete endovascular obliteration at a Radboud - Isala - MUMC+ (RIM) collaborative AVM center in the Netherlands between 2014 and 2022.Additionally, we conducted a systematic review to evaluate the rate of late recanalization following complete endovascular obliteration, confirmed on primary control angiography, in adults with bAVMs. The protocol for this review was registered in PROSPERO (CRD42024546875).Our retrospective study revealed 42 adult patients treated by endovascular means only; 90.5% (38 patients with mean age of 48.1 years) had confirmed complete obliteration. Both primary (6 months post-treatment) and secondary (more than 1 year post-treatment) angiographic control confirmed complete obliteration in 21 of 23 patients with complete follow-up. Mean follow-up was 47.8 months. Two late recurrences (9.5%) were detected at 5- and 6-years' follow-up imaging.Our systematic review included two studies encompassing a total of 19 patients with mean angiographical follow-up of 20.8 months. There were no late recurrences.Late bAVM recurrence after endovascular treatment with proven complete obliteration may be underestimated owing to limited long-term follow-up. Our findings suggest that after a 6-month angiographic confirmed obliteration, a 5-year angiographic imaging control is justified.

Endoscopic submucosal dissection for locally recurrent gastric neoplasia following endoscopic resection: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) for locally recurrent gastric neoplasia following endoscopic resection (ER) is technically challenging because of scar-related submucosal fibrosis. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of salvage ESD in this setting. METHODS: Multiple databases were searched through December 2025 for studies reporting ESD outcomes for locally recurrent gastric lesions at or contiguous with a prior ER scar. Primary outcome was curative resection and need for surgery. Secondary outcomes were en bloc and R0 resection, local recurrence, delayed bleeding, and perforation. Meta-analyses were performed using a random effects model. Heterogeneity was assessed using I2. RESULTS: Seven studies (259 patients; 265 ESDs) were included. Across 5 studies and 243 ESDs, pooled curative resection rate was 69.7% (95% CI, 60.6-78.1; I2 = 38%), while 8.2% (95% CI, 3.3-14.6; I2 = 38.4%) required surgery. En bloc resection rate was 92.3% (95% CI, 79.1-99.7; I2 = 83.7%) across 6 studies, and pooled R0 resection rate was 87.5% (95% CI, 82.1-92.2; I2 = 0%) across 4 studies. Over a mean follow-up of 42 months, pooled local recurrence was 2.0% (95% CI, 0.0-9.7; I2 = 54.1%) across 6 studies. Delayed bleeding was 4.1% (95% CI, 0.8-9.0; I2 = 40.8%) and perforation was 4.1% (95% CI, 1.6-7.3; I2 = 0%). CONCLUSIONS: ESD for locally recurrent gastric neoplasia after ER achieves acceptable curative resection, high en bloc/R0 resection, and low local recurrence and morbidity. It is a viable organ-preserving option for appropriately selected patients, ideally performed at expert centers with close surveillance.

Integrated transcriptomic and metabolomic analyses provide new insights into the response of black rockfish (Sebastes schlegelii) larvae to temperature fluctuations.

Sebastes schlegelii usually encounter elevated and fluctuating water temperatures near its upper thermal limit in summer, yet the hepatic responses of larvae to repeated temperature fluctuation regimes remain unclear. To address this question, S. schlegelii larvae were exposed for 8&#xa0;days to four thermal regimes: constant 18&#xa0;&#xb0;C (CT), constant 28&#xa0;&#xb0;C (HT), intermittent cooling from 18 to 8&#xa0;&#xb0;C followed by recovery to 18&#xa0;&#xb0;C (FL), and intermittent warming from 18 to 28&#xa0;&#xb0;C followed by recovery to 18&#xa0;&#xb0;C (FH). Survival rate was evaluated, and integrated liver transcriptomic and metabolomic analyses were performed. Final survival rates were 96.67% in the CT group, 97.78% in the FL group, and 77.78% in the FH group. Survival rate in the HT group (38.89%) was significantly lower than that in the other three groups (P&#xa0;<&#xa0;0.05). HTvsCT, FLvsCT, FHvsCT, and FHvsHT comparisons identified 2598, 1207, 622, and 2404 differentially expressed genes and 627, 606, 690, and 610 differential metabolites, respectively. KEGG enrichment analyses of DEGs and SDMs in HTvsCT highlighted HSP-mediated proteostasis, endoplasmic-reticulum protein processing, branched-chain and sulfur amino acid metabolism, glutathione metabolism, and central carbon metabolism, with upregulated hsp90aa1, bckdha, gclc, and pfkp and reduced levels of branched-chain amino acids and methionine. Compared with HT, FH showed attenuated disturbances in proteostasis, amino acid and redox regulation, and central carbon metabolism, together with recovery-associated glycerophospholipid turnover. FL primarily induced polyunsaturated fatty acid (PUFA)-related membrane lipid remodeling. These findings indicate that hepatic responses differed between continuous high-temperature exposure and temperature fluctuations and between fluctuation regimes.

Aflatoxins and their biosynthetic precursors in lotus seeds: simultaneous UPLC-MS/MS determination, contamination profiling, and matrix-specific accumulation during Aspergillus flavus infection.

Aflatoxin (AF) contamination poses a severe global threat to food and medicinal material safety, yet existing research focuses on terminal AF metabolites while neglecting residual biosynthetic precursors, leading to potential underestimation of contamination risks. In this study, a UPLC-MS/MS method was established for the simultaneous quantification of six AFs and their five precursors in lotus seeds, with optimization of mass spectrum parameters, chromatographic separation conditions, and sample pretreatment. Method validation confirmed linearity (R2&#xa0;>&#xa0;0.99), LODs (0.03-0.36&#xa0;&#x3bc;g/kg), and recoveries (76.53%-120.0%, RSD&#xa0;<&#xa0;15%). Analysis of 41 natural lotus seed samples revealed a 63.4% AF contamination rate, dominated by B-group AFs, while O-methylsterigmatocystin (OMST) and versicolorin hemiacetal (VOH) were identified as the primary co-residual precursors with co-occurrence rates &#x2265; 50%. Notably, AFM1 was predominantly detected in natural samples with AFB1 concentrations exceeding 100&#xa0;&#x3bc;g/kg. Artificial inoculation experiments further demonstrated that sterilization and sealing conditions modulated AF biosynthesis in lotus seeds, with non-sterilized and non-sealed groups showing delayed fungal metabolism and lower toxin accumulation. A significant linear correlation was observed between AFM1 and AFB1 levels (r&#xa0;=&#xa0;0.94) in infected samples, demonstrating their accumulation levels are coupled with fungal overall metabolic flux. Given the high co-occurrence rate of OMST/VOH with AFB1 in natural samples, their individual and combined toxicities require in-depth investigation. This work deciphers matrix-specific AF dynamics in lotus seeds, supporting regulatory standard refinement (e.g., precursor inclusion) and targeted control (e.g., time-sensitive drying after harvest). Further studies will focus on exploring the molecular mechanisms of substrate-dependent AF synthesis.

Bacterial Lysates Add-On Therapy to Reduce Postoperative Recurrence in Nasal Polyps.

OBJECTIVE: This study aimed to investigate the potential role of OM-85 in reducing polyp recurrence (PR). METHODS: A single-center randomized, prospective study was performed to compare the inter-group PR rate, patient-reported outcome measures (PROMs), CT and endoscopic scores. Hundred patients were randomized to receive either add-on OM-85 (34/50) or control group (43/50); 77 participants completed the 12-month follow-up. The OM-85 group received oral treatment for 10&#x2009;days, followed by a 20-day washout (Months 1-3 and 7-9). Primary outcome was the PR rate. Secondary outcomes included PROMs, Lund-Kennedy (L-K) scores, Lund-Mackay (L-M) scores, and complete blood count (CBC) parameters. RESULTS: The PR rate was significantly lower in the OM-85 group (8.82%) than in the control group (27.91%, &#x3c7; 2&#x2009;=&#x2009;4.408, p&#x2009;=&#x2009;0.036). Univariable analysis identified pre-operative Lund-Mackay (L-M) score (p&#x2009;=&#x2009;0.008) and hyposmia VAS score (p&#x2009;=&#x2009;0.031) as significant predictors of PR. In multivariable analysis, the L-M score remained an independent predictor (OR&#x2009;=&#x2009;1.15, p&#x2009;=&#x2009;0.012), with an optimal cutoff of 10. The OM-85 group showed significant improvements in nasal obstruction, olfactory dysfunction, and mucopurulent discharge at 6 and 12&#x2009;months (p&#x2009;<&#x2009;0.05). Lund-Kennedy (L-K) score and 22-item Sinonasal Outcome Test (SNOT-22) score were also significantly improved (p&#x2009;<&#x2009;0.05). Furthermore, the OM-85 group exhibited elevated white blood cell counts and lymphocyte percentages from 6&#x2009;months onward (p&#x2009;<&#x2009;0.05). CONCLUSION: Adjuvant OM-85 may reduce postoperative PR, with improved endoscopic and symptom scores, potentially mediated by enhanced systemic immune function.

Comparative Effectiveness of Oral Ivermectin, 1% Permethrin Shampoo, and 4% Dimethicone Liquid Gel in Treatment of Pediculosis Capitis among School Children in Chachoengsao Province, Thailand.

Pediculosis capitis remains a persistent public health issue, especially in developing countries where resistance to standard neurotoxic pediculicides like permethrin is increasingly prevalent. This study aimed to compare the effectiveness of alternative treatment options against the standard care in a resource-limited setting. We conducted a single-blind randomized controlled trial involving three primary schools in Chachoengsao Province, Thailand (ClinicalTrials.gov: NCT06332872). Eighty-five female participants ages 6-13 years with active infestations were enrolled. Schools were randomly assigned to three treatment arms: 1) oral ivermectin (200 &#xb5;g/kg) on Days 0 and 7; 2) 1% permethrin shampoo on Days 0 and 7, or 3) 4% dimethicone liquid gel as a single dose on Day 0. The primary outcome was the cure rate, defined as the absence of live lice and viable nits upon clinical assessment on Day 9. Of the 66 participants included in the final per-protocol analysis, oral ivermectin achieved a cure rate of 95.5% (21/22), which was significantly higher than that of the 1% permethrin standard of care (37.0%; 10/27) and the 4% dimethicone physical suffocant (29.4%; 5/17) (P <0.001). Although dimethicone achieved high initial parasitic clearance on Day 0 (88.2%), a rapid reinfestation rate of 58.8% was observed by Day 9, indicating that a single-dose protocol may be clinically insufficient. Adverse events were mild and temporary across all groups. Oral ivermectin appears significantly more effective than both 1% permethrin and single-dose 4% dimethicone in this population. These findings suggest that permethrin resistance is clinically prevalent and relevant in this area.

Postoperative complications and outcomes after surgical treatment for tophaceous gout: A systematic review and meta-analysis.

BACKGROUND: Surgical treatment remains necessary for selected patients with tophaceous gout, particularly when mechanical limitation, nerve compression, ulceration, infection, deformity, or failure of conservative treatment is present. However, postoperative outcomes after surgery for tophaceous gout have not been comprehensively quantified. This systematic review and meta-analysis evaluated postoperative complication profiles and recurrence burden after surgical treatment for tophaceous gout. METHODS: A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted from database inception to March 25, 2026. Original studies reporting postoperative outcomes after surgical treatment for tophaceous gout were included. Pooled event rates with 95% confidence intervals (CIs) were calculated using a random-effects single-arm meta-analytic approach. Primary outcomes were postoperative infection, delayed wound healing, and recurrence. Secondary outcomes were reoperation, amputation, and overall complications. Functional outcomes were summarized descriptively. RESULTS: 18 retrospective studies were included. The pooled postoperative infection rate was 11.3% (95% CI 8.0%-15.7%), delayed wound healing 9.9% (95% CI 5.1%-18.2%), and recurrence 8.5% (95% CI 4.7%-14.9%). Secondary pooled rates were 9.7% (95% CI 5.5%-16.7%) for reoperation, 3.7% (95% CI 2.0%-6.8%) for amputation, and 24.0% (95% CI 14.0%-38.1%) for overall complications. Significant subgroup differences were identified only for infection according to anatomic site and intervention type. Sensitivity analyses showed that pooled estimates were robust. The certainty of evidence was very low for all outcomes. CONCLUSIONS: Surgical treatment for tophaceous gout is associated with measurable postoperative risks, particularly infection and overall complications. These findings support careful perioperative counseling, structured postoperative surveillance, integrated long-term urate-lowering management, and more standardized reporting of perioperative risk factors and postoperative outcomes in future surgical studies of tophaceous gout.

Efficacy of a high-frequency repetitive transcranial magnetic stimulation for craving reduction in adolescents with gaming disorder: a 4-week randomized control trial with 24-week follow-up.

BACKGROUND: With the widespread popularity of online gaming, gaming addiction has come under scrutiny. While there is ongoing research on the diagnosis and treatment of gaming disorder among adolescents, the clinical robustness and reliability of intervention strategies remain uncertain. METHODS: A 4-week, double-blind, randomized, sham-controlled clinical trial was conducted to evaluate the efficacy of noninvasive, high-frequency repetitive transcranial magnetic stimulation (rTMS) in alleviating psychological craving in adolescents diagnosed with gaming disorder. Sham rTMS was administered to the control group using the tilted-coil method. Both groups of participants were treated with SSRI medications. A total of 80 adolescents with gaming disorder participated in this study, and 73 ultimately completed the 24-week follow-up. The primary outcome was the change in craving levels before and after the rTMS intervention, as assessed by the Visual Analogue Scale (VAS). Secondary outcomes included changes in anxiety and depression levels before and after the intervention, as assessed by the HAMA and HAMD. RESULTS: We assessed levels of psychological craving, anxiety, and depression among adolescents with gaming disorder at baseline, after completing a 4-week intervention, and at a 24-week follow-up post-intervention. Our repeated-measures MANOVA results, adjusted for course variables, revealed a significant main effect of rTMS intervention on psychological craving levels in adolescents addicted to online games (F(11, 781)&#x2009;=&#x2009;11.238, P&#x2009;<&#x2009;0.001, partial &#x3b7;&#xb2; = 0.142), as well as significant main effects on time (F(11, 781)&#x2009;=&#x2009;6.809; P&#x2009;<&#x2009;0.001, partial &#x3b7;&#xb2; = 0.091) and group effects (F(1, 71)&#x2009;=&#x2009;26.707, P&#x2009;<&#x2009;0.001, partial &#x3b7;&#xb2; = 0.282). In addition, repeated-measures ANOVA results showed significant time effects for anxiety (F(2, 142)&#x2009;=&#x2009;20.747, P&#x2009;<&#x2009;0.001, partial &#x3b7;&#xb2; = 0.234) and depression levels (F(2, 142)&#x2009;=&#x2009;22.277, P&#x2009;<&#x2009;0.001, partial &#x3b7;&#xb2; = 0.285) among adolescents with gaming disorder, with nonsignificant between-group effects and no intergroup interaction. In the active stimulation group, changes in psychological craving levels after 4 weeks of treatment were significantly and positively correlated with changes in anxiety levels after 4 weeks of treatment in adolescents addicted to online games (r&#x2009;=&#x2009;0.335, P&#x2009;<&#x2009;0.05). CONCLUSION: Our findings indicate that high-frequency rTMS targeting the left dorsolateral prefrontal cortex may be a promising approach for reducing psychological craving in adolescents with gaming disorder.

Efficacy and safety of microwave ablation for the treatment of pulmonary osteosarcoma oligometastases.

PURPOSE: Evaluate efficacy and safety of microwave ablation (MWA) for pulmonary osteosarcoma oligometastases. METHODS: Twenty-two patients (median age, 16&#x2009;years [range, 9-41&#x2009;years]; 15 male) with pulmonary osteosarcoma oligometastases who underwent MWA from January 2018 to December 2023 were included, with 27 MWA sessions for 36 lung metastases. Technical success and complications were evaluated in all 22 patients, while efficacy and survival were evaluated in 19 patients with 24 MWA sessions in treatment of 32 tumors. Technical success was assessed for each tumor. Local tumor control, progression-free survival (PFS) and overall survival (OS) were estimated using Kaplan-Meier method. Complications were classified using Common Terminology Criteria for Adverse Events version 5.0. RESULTS: Technical success was achieved in all 36 tumors (100.0%). Local tumor progression occurred in five of 32 tumors (15.6%). The estimated local tumor control rates at 12, 24 and 36&#x2009;months were 96.9%, 86.1% and 81.5%, respectively. No significant difference in local control was found between tumors &#x2264; 10&#x2009;mm and > 10&#x2009;mm (p&#x2009;=&#x2009;.470). Twelve of 19 patients (63.2%) developed new lung metastases outside the ablation area, including one with concurrent newly developed bone metastases and one with recurrence of primary osteosarcoma. The median PFS was 21.5&#x2009;months. The estimated OS rates at 12, 24 and 60&#x2009;months were 100.0%, 94.4% and 94.4%, respectively. Major complications occurred in five of 27 sessions (18.5%). CONCLUSIONS: MWA preliminarily demonstrates a high technical success rate, notable local tumor control, promising overall survival and acceptable safety for pulmonary osteosarcoma oligometastases.

Recovering membrane interaction kinetics of single molecules from 3D tracking data.

Interactions between cytosolic biomolecules and the bacterial inner membrane are fundamental to many cellular processes, yet directly measuring their binding kinetics in living cells remains challenging. Conventional 2D single-molecule tracking analyses can be insufficient, particularly when membrane association does not markedly alter the diffusion rate. Here, we present a method to recover membrane interaction kinetics from 3D single-molecule trajectories in rod-shaped bacteria. Using simulated 3D tracking data, we identify membrane-associated motion by quantifying how well short trajectory segments follow the circular curvature of the cell membrane. The resulting measure is further analyzed using a hidden Markov modeling framework, enabling robust discrimination between cytosolic and membrane-bound states and capturing the dynamics of state transitions without requiring diffusion-rate changes or direct colocalization with membrane markers. This work establishes a general framework for extracting membrane interaction kinetics from 3D single-molecule tracking data in live bacteria and highlights the value of realistic microscopy simulations for quantitative interpretation and systematic bias assessment.

Spermidine and melatonin ameliorate heat stress-induced decline in sheep semen quality.

Heat stress impairs reproductive performance in sheep through endocrine disruption and oxidative stress. This study evaluated the protective effects of spermidine (SPD) and melatonin (MT) supplementation on semen quality in Dorper rams during summer. Twenty-four rams were randomly assigned to a control group, an SPD group (5&#x202f;mg/kg, dietary supplementation), or an MT group (60&#x202f;mg, subcutaneous implantation) and treated for 60 days. The temperature-humidity index (THI) was monitored throughout the experimental period. Compared with the control group, MT significantly reduced serum cortisol concentration on day 30 (P&#x202f;<&#x202f;0.05), whereas no significant differences were observed at the other sampling time points. Serum testosterone, spermidine, and melatonin concentrations remained unchanged throughout the study (P&#x202f;>&#x202f;0.05). SPD supplementation significantly increased ejaculate volume on day 35 and sperm motility on day 42 (P&#x202f;<&#x202f;0.05), whereas MT did not significantly affect these parameters. Neither treatment reduced the overall sperm abnormality rate. However, both SPD and MT significantly decreased the proportion of acephalic and decaudated sperm on day 56 (P&#x202f;<&#x202f;0.05). Neither treatment significantly affected pregnancy rate, delivery rate, or the expression of PMFBP1 and SUN5 proteins in semen (P&#x202f;>&#x202f;0.05). Regarding oxidative stress, MT significantly downregulated CAT protein expression (P&#x202f;<&#x202f;0.05), whereas SPD significantly reduced MDA content and SOD1 protein expression (P&#x202f;<&#x202f;0.05); MT showed similar but non-significant trends for these two markers (P&#x202f;>&#x202f;0.05). Collectively, these findings demonstrate that SPD and MT exert distinct protective effects against heat stress, with SPD improving selected semen quality traits and both treatments reducing sperm head-tail separation, although these benefits did not translate into improved reproductive performance.

A retrospective population-based cohort study to assess outcomes, time to complications and cost of follow-up care following pediatric pyeloplasty in Ontario, Canada (2002-2016).

PURPOSE: Pediatric dismembered pyeloplasty (PP) is the gold standard surgery for uretero-pelvic junction obstruction (UPJO) in children. However, there is no consensus regarding the duration and methods of providing follow-up care after PP. This study aims to assess the rate of redo-interventions following PP and to define the ideal follow-up care following PP. MATERIALS AND METHODS: This is a retrospective population-based cohort study including all PP patients in Ontario between April 2002 and March 2016 using routinely collected data, with a minimum 5-year follow-up. Baseline variables included demographics, surgical approach, laterality and surgeon experience. The primary outcome was time to secondary surgical intervention, including redo PP. Secondary outcomes included costs of follow-up care and rates of early ER visits. Regression analyses were preformed to predict need for secondary intervention 2-years post PP, including independent variables: age, sex, surgical approach and early complication. RESULTS: The study included 1049 patients with a median age of 2 (IQR 0-7) years. Of the 13.6% of patients who had at least one secondary intervention following PP (including 3.8% who underwent a redo PP), 90.2% occurred within 3-years of PP. The median cost/patient of follow up care was $1472 CAD (IQR $292-$31,133). Regression analysis did not reveal any predictors of delayed secondary intervention. CONCLUSIONS: This study demonstrates that over 86% of PP are completed successfully, with a 3.8% rate of redo-PP. The majority of secondary interventions for post-PP complications occur within 3 years post-PP. Variability in duration and cost of follow-up care post- PP should be addressed to minimize costs, and a minimum 3-years follow-up after PP is recommended.

EDucation and eXercise for gluteal tendinopathy in an Irish context (EDX-Ireland): findings from the LEAP-Ireland feasibility randomised controlled trial.

OBJECTIVE: To assess feasibility of a randomised controlled trial (RCT) investigating effectiveness of 6 sessions of an EDucation and eXercise intervention delivered over 8 weeks (EDX-Ireland) for gluteal tendinopathy, against usual care. EDX-Ireland was modified from a 14-session EDucation and eXercise intervention (EDX), delivered over 8 weeks, previously evaluated in an Australian RCT. DESIGN: Feasibility parallel RCT. METHODS: Participants were randomly assigned to physiotherapist-led EDX-Ireland or usual care. EDX-Ireland comprised 6 sessions of education, hip abductor strengthening and functional loading over 8 weeks, supported by a home exercise programme. Primary outcomes included success of different recruitment strategies and recruitment/retention rates. Secondary outcomes measured global rating of change and other clinical outcomes. Descriptive statistics (percentage, mean, standard deviations and 95% confidence intervals (CI)) are presented. RESULTS: Of 323 individuals who expressed interest in study participation, 119 completed physical examination screening, and 65 met criteria and consented to participate (recruitment rate 55%). Sixty-five people (89% women; mean age 53.1&#x202f;&#xb1;&#x202f;9.3 years), were randomised to EDX-Ireland (n&#x202f;=&#x202f;32) or usual care (n&#x202f;=&#x202f;33). Eighty-three percent (n&#x202f;=&#x202f;54) were recruited via social media/community, 3% (n&#x202f;=&#x202f;2) from general practitioners and 14% (n&#x202f;=&#x202f;9) from orthopaedic/rheumatology. Retention was 92% (95% CI 82-97%, n&#x202f;=&#x202f;60) at 8-weeks, and 89% (95% CI 79-96%, n&#x202f;=&#x202f;58) at 3-months. Feasibility thresholds were met. Effect size estimates indicate that 134 participants would be required for a future RCT. CONCLUSION: Pre-defined recruitment and retention thresholds were met, indicating that a RCT evaluating 6 sessions of physiotherapist-delivered education and exercise against usual care for gluteal tendinopathy is feasible. TRIAL REGISTRATION: Clinicaltrials.gov (NCT05516563).

Optimizing smoking cessation pharmacotherapy and counseling for adult primary care patients: a factorial randomized controlled trial.

BACKGROUND: Even with the most effective smoking cessation pharmacotherapies (i.e., varenicline or combination nicotine replacement [C-NRT]), the majority of people ultimately return to smoking. This research explored how to optimize the use of varenicline and C-NRT to promote smoking cessation. METHODS: Primary care patients participated in a 2x2x2x2 factorial experiment that evaluated 4 factors: 1) Medication Type (Varenicline vs. C-NRT [patch&#xa0;+&#xa0;mini-lozenge]), 2) Preparation (pre-quit) Medication (4 Weeks vs. Standard); 3) Medication Duration (Extended [24&#xa0;weeks] vs. Standard [12&#xa0;weeks]); and 4) Counseling Type (Cessation Counseling [4 sessions] vs. Referral Support [2 sessions focused on use of referral resources]). This study was discontinued prior to reaching the proposed sample size (N&#xa0;=&#xa0;608) due to pandemic-related budgetary constraints. RESULTS: Participants (N&#xa0;=&#xa0;496) were 55% women and 45.6% Black individuals. There were no statistically significant main effects of the 4 factors on abstinence at 12, 26 or 52&#xa0;weeks. There was a 3-way interaction between Medication Type, Preparation Medication, and Counseling Type (p&#xa0;=&#xa0;0.04) predicting the primary outcome of biochemically confirmed abstinence at 52&#xa0;weeks; cessation counseling vs. referral support improved varenicline quit rates when 4&#xa0;weeks versus 1&#xa0;week of pre-quit medication was offered. For C-NRT, counseling type did not significantly improve quit rates regardless of the use of preparation medication. CONCLUSIONS: There was no robust evidence that enhanced pre-quit or extended duration of varenicline or C-NRT increased abstinence rates. More intensive counseling may support cessation for different pharmacotherapy regimens. Given the lack of consistent findings, this research should be viewed as exploratory to guide future research.

Short-term psychodynamic psychotherapy for functional neurological disorder: A pilot randomized controlled trial.

BACKGROUND: Evidence-based psychotherapeutic treatments for Functional Neurological Disorder (FND) remain limited. This pilot trial evaluated the preliminary efficacy of Short-term Psychodynamic Psychotherapy (STPP) plus Standard Medical Care (SMC) compared with SMC alone in reducing FND symptom frequency. METHODS: Adults with FND were randomized (1:1) to receive either SMC alone or 12 weekly sessions of STPP plus SMC. The primary outcome was symptom frequency (days with symptoms in the last 4 weeks) assessed at the end of treatment (3 months) and at 6-month follow-up. Secondary outcomes included treatment response (&#x2265;50% reduction in symptom frequency) and scores on the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), and World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). RESULTS: Of 91 randomized patients (mean age 38.2 years, 75.8% female), 81.3% completed follow-up. Intention-to-treat analysis using Linear Mixed Models showed that STPP plus SMC significantly reduced symptom frequency compared with SMC alone (estimated mean difference -5.72 [95% CI -8.68 to -2.77]; Cohen's d = 0.77; p&#x202f;<&#x202f;0.001).Treatment response was achieved by 65.8% in the intervention group versus 16.7% in controls (OR 8.21 [95% CI 2.79-24.19]; p&#x202f;<&#x202f;0.001; NNT 2.0).Significant improvements were also observed for depression (HAM-D: estimated mean difference -10.80; d = 1.45), anxiety (HAM-A: -7.94; d = 1.06), and disability (WHODAS 2.0: -5.77; d = 0.74), all p&#x202f;<&#x202f;0.001. CONCLUSIONS: STPP was associated with clinically meaningful improvements in FND symptom frequency and all secondary outcomes, with large effect sizes and high treatment response rates. These findings support the preliminary efficacy of STPP for FND and justify larger, multicenter confirmatory trials.
