Background Urinary catheterization is a routine procedure after ureteroscopy lithotripsy URSL , but it often causes catheter-related bladder discomfort (CRBD) and urethral pain, which aggravates patients' postoperative discomfort. This study finds out the effect of topical anesthesia on CRBD and urethra pain in patients undergoing ureteroscopy lithotripsy and urinary catheterization. Methods In this study, 330 patients undergoing ureteroscopy lithotripsy enrolled, with 160 cases in the control group and 170 cases in the experimental group. The experimental group divided into two subgroups based on the local anesthetic used: Tetracaine Hydrochloride Gel subgroup and Oxybuprocaine Gel subgroup. Postoperative assessments conducted using CRBD scores and urethra pain numerical rating scale (NRS) score. CRBD and urethra pain NRS scores measured at T0, T1, T2, T3, T4, T5, and T6. Results Compared to the control group, the use of local anesthetics significantly reduced both CRBD scores and urethra pain NRS scores in the experimental group, with the differences being statistically significant (P < 0.01). In male patients, patients who used local anesthetics markedly decreased CRBD scores and urethra pain NRS scores compared to those not receiving local anesthetics, showing statistical significance (P < 0.01), whereas no significant difference followed in female patients. No statistically significant differences found between Rigid ureteroscopy lithotripsy R-URSL and Flexible ureteroscopy lithotripsy F-URSL) regardless of the use of local anesthetics. Within the experimental group, the effects of different local anesthetics were similar, with comparable impacts on CRBD scores and urethra pain NRS scores, and no statistical differences noted. These findings suggest that local anesthetics are effective in reducing postoperative CRBD scores and urethra pain NRS scores, especially in male patients. Conclusion Topical anesthesia following ureteroscopy lithotripsy reduces CRBD scores and urethra pain NRS scores in patients undergoing urinary catheterization, especially in male patients.

IntroductionPressure sores are a major health problem in people with spinal cord injury resulting in ischaemic tissue lesions caused by prolonged pressure against a bony surface. Conventional therapies are often defective and fundamental researches on the healing process of pressure sores must be enriched in order to understand any novel therapies that may be applied. We focalize on pressure sores fibroblasts as dermal fibroblasts perform a critic role in wound healing by populating the wound site to produce extracellular matrix. After characterizing morphological and the genetic profile of healthy fibroblasts and fibroblasts from pressure ulcers, we conducted an analysis of fibroblast proliferation, migration and myofibroblastic differentiation capacity. Materials and Methodsafter acquisition of dermal explants and fibroblasts culture, we conducted histological analysis, an evaluation of gene expression by RT-qPCR and an assessment of fibroblasts proliferation and migration capacity through IncuCyte. A study of the differentiation of fibroblasts into myofibroblasts through the detection of Alpha-Smooth Muscle Actin (-SMA) expression by immunofluorescence was also conducted. Resultshistological analysis showed histological analysis showed dermal disorganization in pressure sore compared with health skin, differences in morphological aspects and density of fibroblasts. Pressure sore fibroblasts express less genes coding for ECM proteins, metalloproteases, collagen III, Connective tissue growth factor (CTGF) and ACTA2 coding for -SMA. Pathological fibroblasts appear to proliferate less quickly than healthy fibroblasts but no differences in migration capacity were found. After stimulation under TGF-{beta}, pressure sore fibroblasts lose their ability to differentiate into myofibroblasts compared to healthy fibroblasts and this could be in relation with a less expression of ACTA2. ConclusionAll of our results highlight a morphological, genetic and functional difference between healthy and pathological fibroblasts which have a modified phenotype, less effective for skin repair. This suggests that new therapies for chronic wounds must take into account the environment in which they are applied and that pathological cells do not necessarily respond to treatments in the same way as healthy cells. Our results are not statistically significant, although several trends emerge. This is explained by the heterogeneity of the patients medical history and requires repetition of the experiments.

ABSTRACT OBJECTIVE: We performed a systematic review and meta-analysis (SRMA) of post-surgical outcomes, comparing chlorhexidine gluconate (CHG) versus povidone iodine (PI) for vaginal antisepsis of major gynecologic procedures. DATA SOURCES: Ovid Medline, Embase, Scopus, Embase, Cochrane, and Clinicaltrials.gov were searched between 1986 and December 2023, for studies comparing CHG with PI for vaginal antisepsis of major gynecologic operations. STUDY ELIGIBILITY CRITERIA: We included Randomized Controlled Trials (RCTs) and non-RCTs comparing CHG to PI for vaginal antisepsis of major gynecologic operations. The primary outcome was surgical site infections (SSIs) and the secondary outcome was urinary tract infections (UTIs) and vaginal irritation. METHODS: Summary estimates were calculated by fixed effects models when I2 [&le;] 25% and by random effects models when I2 > 25%. Statistical analysis was performed using RevMan 5.4.1. The protocol for this systematic review was registered on PROSPERO (ID CRD42022378101). RESULTS: Nine studies met the inclusion criteria, four of which were randomized controlled trials (RCTs). 9538 patients were included, 4300 (45%) of whom were allocated to CHG and 5238 (55%) to PI. No statistically significant difference in SSI incidence was found for vaginal antisepsis with CHG versus PI in pooled analyses (n= 9538 patients; RR 1.20; 95% CI 0.92-1.57; I2 =0%). In contrast, a significantly higher risk of UTIs was observed for vaginal antisepsis with CHG than with PI (n=6061 patients; RR 1.48 95% CI 1.03-2.14; I2 = 0%). CONCLUSION: In our SRMA, there were no significant differences in SSI risk when either CHG or PI was utilized for antiseptic vaginal preparation. Interestingly, vaginal antisepsis with PI was associated with a lower incidence of post-operative UTIs following major gynecologic surgery. Our findings support current guidelines that form of vaginal antisepsis can be used for SSI prevention. They also suggest that PI may result in fewer postoperative UTIs but further randomized studies are needed to support these findings.

Background Pulse-field ablation (PFA) is regarded as a non-thermal ablation modality, but there is an increasing range of complications that could be due to thermal effects. Methods The hydrogel undergoes permanent colour change when a target temperature is reached allowing direct visualisation of the surface thermal footprint and depth. Comparative lesion sets using a variable loop circular catheter (VP), circular over-the-wire catheter (PS) and pentaspline catheter (FP) were performed. Protocols included single and stacked applications with variation of force, irrigation, and voltage. The hydrogel lesions were analysed en-face and by section using digital image analysis. Results All 3 PFA catheters tested had significant thermal footprints. The VP catheter had the largest mean surface footprint (156.1mm2) and thermal depth (1.31mm) compared to the other two catheters (PS 55.4mm2 & 1.1mm, FP 29.8mm2 & 1.05mm, p<0.005). Increasing irrigation showed a trend to reduce thermal footprint but did not achieve statistical significance. Increasing voltage increased thermal footprint, but increasing force had negligible effect. Stacked lesions incrementally increased thermal lesion footprint and depth in all catheters. Thermal depths of up to 2.4mm were observed. Areas of darkening and degradation of the hydrogel were observed with the VP and FP catheters, consisting of up to 47% of lesion area. No darkening was observed with the PS catheter. Conclusions There are significant thermal footprints in all the systems tested. Temperatures exceeding 60oC have been demonstrated, comparable to radiofrequency ablation, and this may explain the mechanism of injury in some reports of collateral damage during PFA.

OBJECTIVEThis study investigates the long-term impacts of childhood exposure to voiding cystourethrogram (VCUG), a diagnostic procedure for vesicoureteral reflux. Primary outcomes include long-term health outcomes, mental health disorders, healthcare avoidance, and participation in risky behaviors compared to a control group. METHODSA 9-month retrospective cohort study was conducted with adults who received most of their medical care in the U.S. Respondents self-reported health metrics, behaviors, and outcomes via a 20-minute survey. Respondents were divided into two groups: those who remembered undergoing at least one VCUG in childhood (VCUG group), and those who did not (control group). RESULTSOf 334 respondents, 204 (61%) were in the VCUG group (mean age: 29, 70% female) and 130 (39%) were controls (mean age: 34, 70% female). Notable findings include: 47% of VCUG respondents were diagnosed with depression compared to 27% of controls ({chi}{superscript 2} = 13.51, p = 0.0002); 15% of female-born VCUG respondents reported they would never visit a gynecologist compared to 2% of controls ({chi}{superscript 2} = 17.29, p < 0.001); 34% of VCUG respondents smoked regularly compared to 5% of controls ({chi}{superscript 2} = 35.85, p < 0.001); and 11% of VCUG respondents regularly missed work compared to 1% of controls ({chi}{superscript 2} = 11.61, p = 0.0006). These findings highlight the need for further research and clinical consideration of VCUGs long-term consequences. CONCLUSIONSThis study suggests that the effects of childhood VCUG extend into adulthood. Our findings underscore the need to reassess informed consent protocols and consider full-scale studies to minimize bias.

BACKGROUND & AIMS Conventional reusable endoscopes incur significant expenses in the form of purchase, maintenance, reprocessing, and disinfection. Reprocessing is frequently ineffective even following the use of high-level disinfectants (HLDs). Disposable gastroscopy might be a strategy to decrease infectious outbreaks associated with reusable endoscope. The aim of this study was to analyze and evaluate the performance, efficiency and safety in gastroscopy observation and subsequent potential EMR procedure via the disposable gastroscope in a clinical setting. METHODS Patients who required gastroscopies and met the criteria were recruited to this prospective, open-label, non-inferiority study. After obtaining the written informed content, the enrolled subjects selected themselves independently to the disposable group or reusable group. The primary measure was to evaluate the acceptable image quality and whether the disposable endoscope devices could meet the basic clinical demands with a noninferiority margin of -8%. The second measures were to analyze and evaluate the image conditions, accepted endoscopic maneuverability, efficiency and safety of observation and advanced potential EMR procedure. Appropriate statistical methods were conducted via PASS software and SAS 9.4. A two-tailed P value < 0.05 was considered statistically significant. RESULTS A total of 90 individuals (the number of those in disposable group and reusable group was both 45) were recruited to this study. The success rate of acceptable image quality via photographing iconic anatomical sites between two groups was 100.0% (45/45, 95% confidence interval (CI): 0.9213,1.0000) and the lower limit of the 95%CI (-7.8654%, 7.8654%) was larger than the noninferiority margin of -8% (Newcombe-Wilson score method). Significant differences were showed in the measures of image conditions (image acquisition, image quality, brightness, contrast and sharpness) and accepted endoscopic maneuverability (endoscopy body rigidity). No significant differences were observed in the field of knob operation, sharp angle adaptability, and the auxiliary features including air supply, water supply and suction. In terms of efficiency, the total operating time, insertion time and withdrawal time were longer in the disposable group. The En-bloc resection rate of those observed polyps and required to EMR procedure due to relatively larger diameter (5mm-15mm) was the same 100% in both groups (26/26 vs 23/23, 95%CI: 0.8713,1.0000). Nevertheless, the procedure time of EMR for each polyp was significantly longer in the disposable group. This study showed no intraoperative bleeding, delayed bleeding, perforation or other study-related adverse events among 90 patients. No dramatic fluctuations in vital signs were showed in perioperative period. CONCLUSIONS In consideration of the efficiency, efficacy and safety evaluation, the disposable gastroscopes might represent an alternative to conventional reusable gastroscopes in routine examination and endoscopic mucosal resection.

Background Chronic pain is common in adults aged 85 years and older (85+) and is associated with detrimental outcomes. Chronic pain guidelines advise first line management with non-pharmacological measures; paracetamol and non-steroidal anti-inflammatory drugs are the preferred analgesics. Challenges in accessing non-pharmacological therapies for adults aged 85+, and the presence of multimorbidity and polypharmacy, mean that opioid medication is often prescribed for chronic pain despite the potential for opioid-related adverse effects and guidance identifying long-term opioids for chronic pain as a potentially inappropriate prescription. Aim This study aims to explore patient, caregiver, and healthcare professional perspectives on the prescription of opioid medications for pain management for chronic pain in adults aged 85+ to support development of resources for optimising opioid prescribing. Design and Setting In this qualitative study, participants were recruited through primary care, in the community or in care home settings. Method 36 semi-structured interviews were conducted with care home residents and community dwellers aged 85+ (n=12), caregivers (informal and care home staff) (n=12), and healthcare professionals (n=12). Interviews were transcribed and analysed using reflexive thematic analysis. Results Four themes were developed: contextual complexity, satellite influences, balancing act, and pragmatic prescribing. Using opioids in adults aged 85+ is a balancing act to support patients best possible quality of life within their unique circumstances whilst using the pain management tools available. Conclusion Opioids continue to have an important role in pain management in adults aged 85+ largely due to paucity of alternatives and the drive to support quality of life.

BackgroundSnakebite envenoming is a significant global health crisis that has been long neglected as a global health priority. It is a huge problem for rural communities of low and middle-income countries, India accounts for the largest proportion of snakebite deaths globally. Timely identification of venomous snakebite and its syndromic pattern is essential for effective administration of antivenom and supportive treatment. Expert identification of snake species and syndromes is not always available in peripheral healthcare settings. This leads to delays, unnecessary referrals, or improper treatment choices. Additionally, diverse snake species distribution and venom variations across regions pose challenges. AI-powered image classification methods can help overcome these barriers. We propose a clinically oriented deep learning pipeline for binary classification of venomous and non-venomous snake species of India using real-world imagery data. This pipeline would serve as a baseline step towards aiding snakebite management at peripheral healthcare setups with scarce resources. MethodsThe selected dataset consisted of 20 medically important Indian species. MobileViT-S, ConvNeXt-Tiny, EfficientNet-V2-S and ResNeXt-50 (32x4d) were trained under same conditions for comparison of results. Model interpretability was evaluated using Grad-CAM ++ to ensure that classification was not performed based on background but on features like head shape and stripes present on body. For reliable implementation we connected it to a web interface with human in loop expert verification. Experts can confirm or override predictions in real time. ResultsAmong the evaluated architectures, ResNeXt-50 (32x4d) showed the most reliable and consistent performance in classifying venomous and non-venomous snakes. It achieved the highest test accuracy, sensitivity, specificity, and F1-score. The model also had strong discriminative ability, with a ROC-AUC of 0.9950 and PR-AUC of 0.9959. These results indicate dependable performance in safety-critical screening situations. Grad-CAM++ visualizations confirmed that predictions were based on anatomically relevant features, especially in the head and body contour areas. This supports model interpretability and reduces background bias. ConclusionsAlthough the dataset size and single-institution source limit how widely the results can be applied, the proposed framework shows that its possible to create a clinically oriented, ready-to-use deep learning system for snakebite triage support. This system is intended as a scalable tool to help rural healthcare workers, emergency responders, and telemedicine platforms in areas where snakebites are common. Author SummarySnakebite is a major public health concern that disproportionally affects the rural population. Delays in identifying whether a snake is venomous often lead to delayed treatment, unnecessary use of antivenom, or inappropriate referrals. In many rural settings, access to expert snake identification is limited. To address this gap, authors have developed an artificial intelligence (AI)-based image classification system that distinguishes snakes into two clinically relevant categories: venomous or non-venomous. Unlike many previous studies that focused on ideal, high-quality wildlife images, our model was trained using real-world photographs captured in emergency situations, including images taken by patients and field responders under variable lighting and background conditions. This approach improves the models relevance to practical healthcare settings. The system achieved high accuracy and was further strengthened by visual interpretability tools and expert verification to ensure reliability. By combining AI-assisted classification with human oversight, this work provides a scalable decision-support tool that may improve early triage, rational antivenom use, and surveillance in snakebite-endemic regions

Introduction Aquablation for surgical treatment of benign prostatic enlargement (BPE) causing bladder outflow obstruction (BOO) has demonstrated good functional outcomes, even for large glands, with high rates of ejaculatory preservation reported. This is a protocol for a study that aims to review real-world outcomes of ejaculatory preservation or restoration post-Aquablation in an unselected cohort and compare to published clinical trial outcomes. Methods Retrospective data will be collected from a prospectively maintained consecutive case series of patients who underwent Aquablation, in a single UK centre. The primary outcome is ejaculatory function subjectively reported by men post-operatively, and classified as: antegrade ejaculation, retrograde/low volume ejaculation, anejaculation or not sexually active. Secondary outcomes are International Prostate Symptom Severity (IPSS), Quality of Life (QoL) Score, post-void residual (PVR), and incontinence. Descriptive and comparative statistical tests will be performed. Conclusions This study will review real-world ejaculatory function and clinical outcomes following robotic Aquablation for prostatic bladder outflow obstruction and compare this to published clinical trial outcomes.

OBJECTIVESDemonstrate correlations of clinic-based measures of International Classification of Functioning, Disability and Health (ICF) Body Structure and Function, capacity and performance with a school-based performance measure in children with Cerebral Palsy (CP) using a transdiagnostic approach. METHODS102 ambulatory children with CP underwent assessment of Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Pediatric Quality of Life Inventory Generic Core Scales (PedsQL), 3-Dimensional Gait Analysis, Gillette Functional Assessment Questionnaire (GFAQ), and Pediatric Outcomes Data Collection Instrument (PODCI) done in clinics, compared with School Function Assessment (SFA) done in schools. Here we report on SFA correlations. For this paper, Spearmans correlations were calculated. RESULTSAll measures showed some significant correlations with the SFA; greatest number of moderate to strong correlations were with PODCI, including PODCI comorbidities scales. PODCI performance questionnaire was correlated with all SFA scales. PODCI, as a performance measure, is broader, more holistic, than the capacity and BSF measures. Findings are demonstrative of a focus on the ICF approach, indicating separate domains of function and well-being, reflective of the transdiagnostic approach. CONCLUSIONSThe transdiagnostic approach, looking at a broader picture than simply diagnosis, thus paralleling concepts presented in the ICF, is beneficial in assessing functioning and well-being in children with CP.

BackgroundHand hygiene remains a cornerstone of infection prevention in surgical practice, particularly in orthopedic operating theatres where inadequate aseptic technique can increase the risk of surgical site infections and implant-related complications. Despite well-established recommendations from the World Health Organization (WHO) regarding proper surgical hand-scrubbing techniques, compliance in many healthcare settings remains inconsistent. Clinical audits provide a structured approach to evaluating adherence to such guidelines and implementing targeted improvements. This study aimed to assess baseline hand-scrubbing practices in an orthopedic operating theatre at a regional hospital in northern Pakistan and evaluate the impact of educational interventions on compliance with WHO standards. MethodsA prospective closed-loop clinical audit was conducted in the orthopedic operating theatre of Regional Headquarter Hospital Skardu, Pakistan, from December 1, 2025, to February 1, 2026. Approximately 40 healthcare personnel, including consultants, residents, nurses, and operating theatre assistants, participated in the audit. Baseline hand-scrubbing practices were observed during routine surgical sessions using a structured checklist based on WHO hand hygiene guidelines. Following the baseline assessment, educational interventions were introduced, including live demonstrations of correct hand-scrubbing techniques and placement of visual reminder posters in the scrub area. Post-intervention compliance was re-evaluated using the same checklist. Compliance rates before and after the intervention were compared using appropriate statistical analysis, with significance set at p < 0.05. ResultsBaseline observations revealed suboptimal compliance with recommended hand-scrubbing standards, particularly with regard to scrubbing duration, coverage of all hand surfaces, and proper drying technique. Following the educational intervention, significant improvements were observed across all evaluated components. Compliance with scrubbing duration of at least two minutes increased from 45% to 90%, coverage of all hand surfaces improved from 50% to 88%, proper antiseptic usage increased from 60% to 93%, and correct drying technique improved from 55% to 87%. Adherence to overall aseptic protocol also increased from 70% to 95%. All observed improvements were statistically significant (p < 0.001). ConclusionsThis prospective clinical audit demonstrates that structured educational interventions, including live demonstrations and visual reminders, can significantly improve compliance with recommended hand-scrubbing practices in orthopedic operating theatres. Regular audits combined with targeted educational strategies represent practical and cost-effective measures for improving infection control practices and enhancing patient safety in surgical settings.

Sexual abuse among adolescent girls is underreported in low and middle income countries including Nepal. This study aimed to estimate the prevalence of SA among school girls, examined associated sociodemographic and contextual factors describe the nature and reporting patterns of abuse and assess the relationship with nutritional status. A school based cross sectional study was conducted, among 330 female students (ages 14-19) were selected through simple random sampling from two schools. Data were collected using a validated self-administered questionnaire covering demographic characteristics, abuse experiences, psychosocial responses and reporting patterns. Anthropometric measurements were used to assess BMI-for- age and height-for-age Z scores calculated using WHO AnthroPlus. Logistic regression analysis was used to identify factors independently associated with sexual abuse and adjusted odds ratio with 95% confidence intervals were calculated. SA prevalence was 33.3%. Most perpetrators were male (61.5%) and known to the victim, 63.3% involved perpetrator use. Reporting was low (16.5%) due to fear (42.2%) and shame (22%). Significant predictors included lower maternal education (AOR=3.03) and living in joint families (AOR=2.34).After adjusting for confounders, SA was strongly associated with thinness (AOR=5.59; 95% CI; 2.54-12.26), severe thinness (AOR=18.81; 95% CI: 4.21-84.07) and stunting (AOR=3.79; 95% CI: 1.88-7.62). One in three girls experienced sexual abuse, which is strongly correlated with growth impairment and malnutrition. These findings suggest that anthropometric deficits may serve as clinical red flags for underlying trauma. Strengthening school-based nursing programs and primary care screening is essential for early identification and safeguarding.

BACKGROUND: Prostate cancer (PrCa) is the most commonly diagnosed cancer in men in many countries and is the most heritable of the common cancers. Precision medicine approaches to disease management are not routinely available to most men, yet we know that germline genetic testing can help identify those at high-risk of developing advanced or lethal disease and can influence selection of therapeutics. An integral part of healthcare delivery design is the inclusion of patients/consumers in the development of frameworks for managing health interventions that are tailored to meet their needs. METHODS: In Phase I, we undertook focus group discussions with men previously diagnosed with PrCa (n=20), to determine their opinions, perceptions and expectations of germline genetic testing for PrCa. Focus groups were tape-recorded, transcribed verbatim, coded and then thematically analysed using NVivo. In Phase II, themes were then used to design and development a Precision Medicine in Prostate Cancer Information Toolkit, which was reviewed by patients (n=14), their carers/family members (n=4) and healthcare providers (n=14). RESULTS: In Phase I, knowledge about precision medicine and genetic testing was generally low. The strongest motivation for undertaking testing was to identify family members' risk levels (n=7), and the biggest concern pertained to insurance discrimination (n=5). Phase II data revealed that generally healthcare providers (n=8) found the purpose of the toolkit to be clearer than patients (n=5). Though, patients found the task of imagining the usefulness of the toolkit at the time of diagnosis or beforehand when assessing genetic risk, quite difficult. Participants highlighted that information regarding life insurance, implications for their family and costs associated with testing were of concern. CONCLUSIONS: This study has revealed critical knowledge gaps, preferred communication/support needs, and concerns/risks associated with germline genetic testing in PrCa. Concerns pertaining to family members and insurance discrimination are obvious topics that need to be addressed. Our toolkit may be helpful in addressing knowledge gaps, but further testing is needed to ensure its accessibility across literary and cultural contexts.

Background: Orthopedic surgeries are associated with significant intraoperative and postoperative pain, necessitating effective anesthesia strategies. Spinal anesthesia is commonly used for lower limb procedures due to its rapid onset and reliability; however, its limited duration may compromise prolonged surgical procedures and early postoperative pain control. Adjuvants such as dexamethasone have been explored to enhance and prolong the effects of local anesthetics. While evidence supports its efficacy, data from low-resource settings remain limited. Objective: To assess the effect of intrathecal dexamethasone as an adjuvant to bupivacaine on sensory block duration, time to first postoperative analgesia, and postoperative pain in patients undergoing lower limb orthopedic surgery at KCMC. Methodology: A randomized, double-blind controlled trial was conducted among 96 adult patients undergoing elective lower limb orthopedic surgery under spinal anesthesia. Participants were allocated using a computer-generated randomization sequence to receive either bupivacaine 15 mg with dexamethasone 4 mg (intervention group) or bupivacaine 15 mg with 1 ml normal saline (control group). Outcomes included sensory and motor block duration, time to first postoperative analgesia, and postoperative pain scores. Results: The dexamethasone group demonstrated a significantly prolonged sensory block duration (231 +/- 6 vs. 156 +/- 9 minutes; mean difference 75.11 minutes, 95% CI: 71.92-78.29; p < 0.001) and delayed time to first postoperative analgesia (252 +/- 7 vs. 181 +/- 7 minutes; mean difference 71.89 minutes, 95% CI: 68.91-74.86; p < 0.001). Motor block duration was also significantly longer (184 +/- 7 vs. 130 +/- 5 minutes; mean difference 53.42 minutes, 95% CI: 50.99-55.85; p < 0.001). Postoperative pain scores were significantly lower at 1 hour (mean difference -1.29 points, 95% CI: -1.52 to -1.05; p < 0.001) and at 2 hours (mean difference -1.97 points, 95% CI: -2.21 to -1.73; p < 0.001). Intraoperative opioid and benzodiazepine use were significantly reduced in the intervention group. Conclusion: The addition of intrathecal dexamethasone to bupivacaine significantly enhances sensory block duration, delays postoperative analgesia need, and improves early pain control. These findings support its use as a potentially practical adjuvant in resource-limited settings.

BackgroundReusable menstrual products provide sustainable and cost-effective alternatives to disposable sanitary products; however, their adoption remains limited, even among healthcare professionals. ObjectivesTo assess awareness, knowledge, perceptions, and utilisation of reusable menstrual products among female medical students and healthcare professionals, and to identify predictors of willingness and use. DesignCross-sectional analytical study. SettingAn online survey was conducted among female medical students and healthcare professionals in Nigeria. ParticipantsA total of 203 female respondents aged 15-55 years. InterventionNot applicable. Primary Outcome MeasuresUtilisation of reusable menstrual products and willingness to adopt their use. Secondary Outcome MeasuresAwareness, knowledge, perceptions, and barriers. MethodsData were collected using a structured questionnaire and analysed using descriptive statistics, chi-square tests, and logistic regression. ResultsAwareness was high (96.06%), but utilisation was low, with 5.42% ever using and 4.43% currently using reusable products. About 31.53% were willing to use them. Respondent type was not associated with willingness (p = 0.735), although healthcare professionals had higher knowledge (p = 0.024). Positive perception predicted willingness (AOR = 7.58, 95% CI: 3.18-18.03, p < 0.001). Good knowledge (AOR = 14.96, p = 0.014) and increasing age (AOR = 1.28, p = 0.004) predicted utilisation. ConclusionDespite high awareness, utilisation remains low. Perception influences willingness, while knowledge drives use. Targeted behavioural and educational interventions are needed.

ObjectivesTo investigate the epidemiology of acute sports-related upper-extremity injuries in young athletes, with a particular focus on the frequency, anatomical distribution, injury types, and mechanisms of digit injuries. MethodsThis single-center retrospective observational study included athletes aged [&le;]22 years who sustained acute sports-related upper-extremity injuries between January 2017 and November 2025. Digit injuries were defined as injuries involving the thumb and fingers at or distal to the metacarpophalangeal joint. Injury characteristics, mechanisms, and sports categories were analyzed using descriptive statistics. ResultsA total of 1,219 acute sports-related upper-extremity injuries were analyzed. Digit injuries were the most common injury location, accounting for 412 cases (33.8%), followed by shoulder (30.7%), elbow (17.5%), wrist (14.4%), and palm injuries (3.6%). Jammed finger was the most frequent injury type, comprising 64.8% of digit injuries, followed by fractures (20.1%) and dislocations (5.3%). Most injuries were caused by contact mechanisms (90.3%), with ball contact being the predominant cause (49.5%). Ball sports accounted for 85.4% of all digit injuries. ConclusionsDigit injuries represent the most frequent acute sports-related upper-extremity injuries in athletes aged [&le;]22 years, with jammed finger accounting for the majority of cases. Most injuries were associated with ball contact, highlighting the need for preventive strategies and appropriate initial management for digit injuries in young athletes.

Abstract Background Peripheral artery disease (PAD) is a major contributor to morbidity and mortality, particularly among individuals with diabetes mellitus (DM), in whom its prevalence is markedly increased. PAD is often asymptomatic and under-diagnosed, especially in low-resource settings. This study aimed to determine the prevalence of PAD and associated factors among adults with DM in Eastern Uganda. Methods We conducted a hospital-based cross-sectional study at Mbale Regional Referral Hospital from 10th/12/ 2024 to 30th/4/2025. A total of 300 adult patients with DM were consecutively enrolled. Data on sociodemographic characteristics, clinical characteristics, comorbidities, and behavioural risk factors were collected using an interviewer-administered data tool. PAD was assessed using the ankle-brachial index (ABI), defined as [&le;] 0.90. Modified Poisson regression was used to identify factors associated with PAD. As a secondary measure for PAD, we administered the Edinburgh Claudication Questionnaire (ECQ) to capture symptomatic PAD. Results The majority of the participants had a low fruit intake (68%), physical inactivity (54%), and elevated low-density lipoprotein (60%). The prevalence of PAD as measured by ABI was 42.3% (127/300; 95% CI 0.38-0.48), while the magnitude of PAD as measured by ECQ, combining participants with possible claudication and definite claudication was 37.3% 95% CI 31.9 - 42.8). Out of participants with PAD, 15.8% (20/127) were classified as having severe PAD (ABI <0.4). Socio-demographic and clinical factors were assessed for association with PAD. We found no evidence of association between the examined factors such as age (aPR 1.24 95% CI 0.73 - 2.09), sex (aPR 1.46 95% CI 0.84 - 2.55), cholesterol level (aPR 1.39 95% CI 0.86 - 2.25), glycemic control (aPR 1.35 95% CI 0.72 - 2.53), and sedentary behaviour (aPR 1.28 95% CI 0.79-2.08) and PAD. Conclusion The prevalence of PAD was high among adults with DM in Eastern Uganda. Routine health education, and ABI screening of PAD should be done for patients living with DM. The absence of significant associations despite high prevalence of PAD may reflect unmeasured factors e.g. chronic inflammation that may be unique to this population, future prospective studies with larger sample size and more detailed objective measures e.g. inflammatory markers are needed to determine locally relevant modifiable risk factors.

BACKGROUNDSotalol loading intravenously enables achieving blood levels of sotalol that are observed at maximal steady-state concentration (Cmax ss) in one-day permitting the measurement of maximum QTc effects. Rapid evaluation of the QTc effects permits determination of arrhythmic risk and thus permits discharge in 24-hours instead of the usual three-day oral load hospitalization. Given the expense of IV Sotalol an oral loading test strategy is presented that also achieves Cmax ss blood levels rapidly, permitting a one-day hospitalization for QTc evaluation. METHODPharmacokinetic parameters referred to in the literature derived from normals as well as patients was utilized for population pharmacokinetic modeling and simulation.to obtain the Cmax ss concentrations for patients with normal renal function, creatinine clearance (CrCl) > 90 ml/min), as well as for patients with a CrCl of 60-89, 30-59, and 10-29 ml/min). Using pharmacokinetic simulations, an oral loading dose, as well as a second oral dose were determined that would reach the estimated Cmax ss in each of the groups based on renal function. RESULTSFor target dosing of 120 mg oral sotalol BID in patients with a CrCl >90 ml/min an oral loading dose of 200 mg provides a peak sotalol level of 1,420 ng/ml in 3-4 hours post dosing. The Cmax ss target is 1,299 ng/ml resulting in a 9% overshoot. The Cmax ss concentration provides a means of evaluating QTc effects within 24-hours. Oral loading regimens are described for varying additional renal function levels (CrCl 60-90, 30-59 and 10-29 ml/min) along with the time to first oral dose and follow-up dosing. The initial test dose can be based on an 80 or 120 mg oral sotalol maintenance dosing strategy. CONCLUSIONSEmploying an oral loading strategy may permit QTc evaluation and one-day discharge, preserving the pharmacoeconomic advantage of a Cmax ss test strategy.

Study design A retrospective case control study Objective To predict proximal junctional kyphosis (PJK) risk by normalizing individual vertebral bone strength using the ratio of vertebral Hounsfield unit (HU) values around the upper instrumented vertebrae (UIV). Summary of background data PJK poses a significant challenge in treating patients after adult spinal deformity (ASD) surgery. While the vertebral body HU value is associated with PJK risk, the optimal threshold remains unclear, and a relative assessment of HU values within individuals has not been conducted. Methods Data on patients who underwent corrective fusion of the middle to lower thoracic region of the pelvis for ASD were assessed. The 126 patients were categorized into PJK and non-PJK groups. We compared the patients' backgrounds, vertebral body HU, and junctional HU ratio, defined as the HU value of UIV+1 divided by the HU value of UIV (HUUIV+1/HUUIV). The UIV+2/UIV+1 HU ratio was calculated similarly. Results The PJK and non-PJK groups included 30 and 96 patients, respectively. After propensity score matching, 28 patients from each group were analyzed. HU values at UIV+2 and UIV+1 (117.0 {+/-} 46.6 vs 145.1 {+/-} 45.9, p=0.018, and 105.5 {+/-} 36.2 vs 147.3 {+/-} 44.9, p<0.001, respectively) were lower in the PJK group. Junctional HU ratio was significantly lower in the PJK group (0.88 {+/-} 0.18 vs 1.13 {+/-} 0.25, p<0.001), and receiver operating characteristic analysis showed that the junctional HU ratio had the highest discriminative ability (area under the curve 0.812). At the optimal cutoff value (HU ratio of 0.905), the sensitivity and specificity for PJK were 64.3% and 89.3%, respectively. Conclusions A low junctional HU ratio was strongly associated with PJK after ASD surgery. This parameter reflects the bone strength mismatch at the proximal junction and may help improve preoperative risk assessment and UIV selection.

OBJECTIVES: Compare results of the Pediatric Outcomes Data Collection Instrument (PODCI) in children ages 2-18 years with cerebral palsy (CP) across all severity levels of the Gross Motor Function Classification System (GMFCS) with children in the General Population, confirming discriminant validity as a performance assessment tool and health-related quality of life (HRQOL) measure. METHODS: Cross-sectional study: single response PODCI proxy survey databases of 5238 children ages 2-18 years in GP and 2470 in the Population with CP were analyzed. Statistical methods included Analysis of Variance (ANOVA), Analysis of Covariance (ANCOVA), Linear Trend Test, and Standard Error Assessment. RESULTS: A statistically significant difference exists between PODCI subscales in General Population and Population with CP across age groups and GMFCS levels. Motor scales and Global Functioning increase with age in both populations and are inversely proportional to GMFCS level in the Population with CP. HRQOL measures decrease with age in both populations with Happiness decreasing more in the General Population than those with CP as age increases. CONCLUSIONS: PODCI demonstrates a statistically significant difference in motor performance and HRQOL in children ages 2-18, between the General Population and the population with CP. PODCI is a valid performance assessment tool for use in CP ages 2-18 across all GMFCS levels. KEYWORDS: Cerebral Palsy, General Population, PODCI, ICF, Performance
