Background: Obstructive jaundice is a clinical condition caused by obstruction of the bile flow system and manifests as discolouration of the eyes and skin. The prevalence of malignant jaundice in nearby African nations is unacceptably high. Furthermore, there is local suspicion that gold mining activities are behind the high number of cancer patients in the northern region of Sudan. This study aims to identify the prevalence of malignancy among obstructive jaundice patients in the study area. Methods: We performed a hospital-based cross-sectional review of 60 consecutive patients diagnosed with obstructive jaundice at three major hospitals in Dongola between January and July 2024. Malignancy was defined by imaging and histopathology. Data were extracted from hospital records and supplemented by telephone interviews when records were incomplete. Descriptive statistics, bivariate tests, and multivariable logistic regression were used to compare malignant and benign cases; significance was set at p < 0.05. Analyses were performed using SPSS v27. Results: Malignancy accounted for 31/60 (51.7%) of obstructive jaundice cases. The most frequent malignant diagnoses were hepatocellular carcinoma (9/31, 29.0%) and carcinoma of the pancreatic head (8/31, 25.8%). Malignant cases more often reported weight loss, vague abdominal pain, dark urine, and pruritus, whereas right upper quadrant pain was more frequent in patients with benign disease. Mean serum bilirubin was significantly higher in malignant versus benign cases (11.2 mg/dL vs 5.0 mg/dL). In multivariable analysis (complete cases, events = 22), age and serum bilirubin remained independent predictors of malignancy (age aOR 1.47 per 10 years, 95% CI 1.07 - 2.01; bilirubin aOR 2.03 per 5 mg/dL, 95% CI 1.86 - 2.45). Metastasis showed a strong trend but did not reach significance. Gold mining exposure was significantly associated with malignancy in univariate analysis but lost significance when undergoing multivariable regression testing. Smoking and sex were not significant. Conclusion: In this hospital series from Dongola, over half of obstructive jaundice presentations were due to malignancy, with hepatocellular carcinoma and pancreatic head carcinoma being the most common. High bilirubin levels and older age were independent predictors of malignancy. Residence near gold mining areas was associated with malignancy in descriptive analyses but did not remain significant after adjustment; this finding is hypothesis-generating and requires environmental and epidemiologic follow-up.

Objective To develop and validate a risk model for predicting postoperative bleeding in patients with thyroid cancer. Methods A total of 2800 consecutive patients diagnosed with thyroid cancer in the Department of Thyroid and Breast Surgery of the Affiliated Hospital of Xuzhou Medical University between January 2020 and December 2023 were retrospectively analyzed. Patients were categorized into two groups based on postoperative bleeding occurrence: bleeding and non-bleeding groups. Univariate and multivariate logistic regression analyses were utilized to screen independent risk factors. Meanwhile, risk prediction models were developed and nomogram . Subgroup analysis was performed to identify independent risk factors. The predictive effects of the models were assessed using the Hosmer-Lemeshow test and receiver operating characteristic (ROC) curves. Results Of the 2800 recruited patients, 50 had postoperative bleeding, with an incidence rate of 1.7%. Multivariate logistic regression analysis showed that age, hypertension, total thyroidectomy, tumor size [&ge;]4 cm, and operation time [&ge;]90 min were the risk factors for postoperative bleeding in thyroid cancer patients (P<0.05). A risk prediction model was established based on the above factors, and the area under the ROC curve was 0.881, with a sensitivity of 94.0%, a specificity of 67.3%, and an accuracy of 74.0%. Decision curve analysis revealed that the model had good predictive ability. Conclusions The constructed risk prediction model has good predictive power and can provide a reference for healthcare professionals to predict the risk of bleeding in patients after thyroid cancer surgery.

Background: Lung cancer is leading cause of cancer related death globally. It is second most prevalent cancer among women worldwide and ranks third among females in Nepal. Contributing factors are smoking, tobacco use, air pollution, and delayed diagnosis. Image-guided fine needle aspiration cytology (FNAC) is rapid diagnostic technique for evaluating lung lesions. It is minimally invasive procedure with less complications. This study examine histocytologic makeup of lung lesions and link the results. Materials and Methods: This cross-sectional observational study included 65 patients irrespective of age and sex presenting with lung masses at Chitwan Medical College and Teaching Hospital from April 2023 to September 2024. After clinical and radiologic evaluation, all cases underwent image-guided FNAC and biopsy. Only specimens with unequivocal malignant features were classified positive. Histopathology served as diagnostic reference standard. Results: FNAC diagnosed 90.8% as malignant and 9.2% as benign. Biopsy confirmed malignancy in 92.3% of cases. FNAC demonstrated a sensitivity of 98.33%, specificity of 100%, positive predictive value(PPV) of 100%, and negative predictive value (NPV) of 83.33%. Concordance between FNAC and histopathological subtyping was 98.46%. Adenocarcinoma was most common subtype, followed by Squamous cell carcinoma(SCC) and small cell carcinoma. Smoking was most common contributing factor associated with malignancy. Conclusion and implications: Image-guided FNAC is an excellent diagnostic accuracy tool which possess higher level of concordance with biopsy in evaluating lung masses. It should be considered as frontline diagnostic tool, especially in resource limited settings. Keywords: FNAC, Lung cancer, Biopsy, SCC, Adenocarcinoma, Small cell carcinoma, Nepal

Effective postoperative pain control is essential following laparoscopic cholecystectomy, yet the analgesic value of a standardised 150 mg preoperative dose of pregabalin has not been clearly established. This systematic review and meta-analysis synthesised evidence from seven randomised controlled trials published between 2008 and 2025 to evaluate the efficacy and safety of pregabalin when administered before surgery. Four trials reported 24-hour postoperative pain scores, and pooled analysis demonstrated that pregabalin significantly reduced pain compared with control (SMD = 0.80 lower; 95% CI, 1.42 to 0.18 lower; p = 0.01), although statistical heterogeneity was high (I-squared = 81%). Pregabalin also produced notable reductions in opioid consumption, including fentanyl (SMD = 1.24 lower; p = 0.002) and tramadol (SMD = 4.21 lower; p = 0.002), again with considerable variability across studies. Sedation was slightly increased but did not reach statistical significance, and there were no significant differences in postoperative nausea, vomiting, or headache. Sensitivity analyses supported the stability of these findings. Overall, the results indicate that a single 150 mg preoperative dose of pregabalin meaningfully reduces postoperative pain and opioid requirements following laparoscopic cholecystectomy while maintaining an acceptable safety profile, supporting its use as part of a multimodal analgesic strategy.

Introduction: The advent of Endovascular surgery and the use of fluoroscopy-guided procedures have grown in the last decade, and with that increased the exposure of surgeons to cumulative ionizing radiation, increasing the risk of occupational health complications. Despite established radiation protection principles, adherence to radioprotection measures and surveillance practices remains uncertain in many settings. This study aimed to evaluate knowledge, availability, and implementation of radiation protection strategies among vascular surgeons in Brazil Metology: A national cross-sectional survey was conducted in February 2026 using an anonymous online questionnaire distributed to all active members of the Brazilian Society of Angiology and Vascular Surgery (SBACV). Associations between participant characteristics and radioprotection practices were explored using chi-square or Fishers exact tests. Results: Of 4,698 invited members, 192 vascular surgeons met the inclusion criteria. Most participants were male (67.4%), with a mean age of 45.9 years and a median of 12 years of experience performing fluoroscopy-guided procedures. Basic PPE use, particularly lead aprons, was nearly universal; however, adherence to other protective measures was substantially lower. Most respondents reported employing radiation-reduction strategies, including minimizing fluoroscopy time (98.9%), collimation (90.6%), optimized table and detector positioning (88.3%), procedural planning (87.2%), and pulsed fluoroscopy (81.0%). Only 19.4% reported undergoing annual medical surveillance for radiation-related health effects. Cataracts were the most frequently reported radiation-associated condition (6.2%). Greater age and professional experience were associated with higher utilization of selected protective measures and advanced imaging strategies. Conclusion: The study provides important insights into how radiation protection is currently understood and implemented in contemporary Brazilian vascular surgery practice. The incomplete use of personal protective equipment (PPE), with many justifications in addition to the low surveillance of the effects of radiation on health, brings us an alert about the reality in Brazil.

Background Bone-avid tracer myocardial scintigraphy for the diagnosis of transthyretin amyloid cardiomyopathy (ATTR-CM) has traditionally employed imaging at one or 3-hour intervals. Technetium-99m hydroxydiphosphonate (99mTc-HDP) has unique characteristics that may enable earlier imaging. We investigated the diagnostic concordance of immediate versus 1-hour acquisitions. Methods Consecutive patients with suspected ATTR-CM underwent planar imaging and SPECT/CT immediately and at 1-hour following the administration of 99mTc-HDP. Perugini grades and heart to contralateral lung (H/CL) ratios were assessed. Target-to-background ratios (TBRs) were calculated on the SPECT/CT acquisitions using the left ventricular (LV) septum and three background regions: aorta, LV blood-pool, and vertebrae. We assessed diagnostic concordance using Cohen's Kappa ({kappa}), temporal stability using paired t-tests, and correlation between timepoints using Pearson's coefficient (r). The 1-hour SPECT/CT interpretation served as the protocol reference standard. Results Forty-eight patients (83% male; median age, 80 [73-85] years) were evaluated. One-hour SPECT/CT identified 19 positive and 29 negative cases. Immediate SPECT/CT demonstrated 100% diagnostic concordance with the 1-hour reference standard ({kappa} = 1.000; 95% CI: 1.00 to 1.00; p < 0.001). The LV septum/LV Blood-Pool TBR showed the highest correlation (r = 0.956; 95% CI: 0.922 to 0.975; p < 0.001). The LV Septum/Aorta TBR demonstrated high correlation (r = 0.918; 95% CI: 0.857 to 0.953; p < 0.001) and remained stable in the ATTR-negative cohort (-0.02; 95% CI: -0.08 to 0.04; p = 0.54). Significant decrease in the LV Septum/Vertebrae TBR in the ATTR-negative (-0.55; 95% CI: -0.64 to -0.47; p < 0.001) and ATTR-positive cohorts (-1.14; 95% CI: -1.39 to -0.89; p < 0.001) was observed. Conclusions Immediate 99mTc-HDP SPECT/CT is diagnostically concordant with standard 1-hour protocols. By leveraging SPECT/CT and the favorable kinetics of 99mTc-HDP, immediate-phase imaging can accurately reproduce 1-hour acquisitions in cases of suspected ATTR-CM. This expedited approach may improve nuclear laboratory throughput and patient satisfaction.

Background: Blood-based colorectal cancer (CRC) screening is a novel, less invasive screening that has the potential to improve CRC screening adherence, particularly among Black American populations, which has historically lower screening rates. We evaluated factors associated with preference for blood-based CRC screening among Black adults in church-based community settings. Methods: From October 2023 to January 2024, a cross-sectional survey was conducted over 101 adults aged 45 to 75 years at three Black churches in metropolitan Atlanta, Georgia. Demographics, CRC screening history, healthcare access, and attitudes toward blood-based CRC screening were assessed. Results: Overall, 72 participants (71.3%) preferred blood-based CRC screening. Preference was not associated with demographic or socioeconomic characteristics, screening history, or healthcare access. The most commonly reported reasons for ease of testing (83.3%), avoidance of stool collection (38.9%), avoidance of bowel preparation (36.1%), perceived fewer side effects (34.7%), and perceived lower risk (33.3%). Needle concerns were the only factor significantly associated with non-preference (p=0.034). Conclusion: Blood-based colorectal cancer screening was preferred by most Black adults and may improve CRC screening participation through greater convenience.

Background Menstrual cycle disturbances have been increasingly reported after COVID-19 vaccination, raising questions about their prevalence and clinical significance among women of reproductive age. Objective This study aimed to investigate the incidence and types of menstrual cycle alterations following different doses of COVID-19 vaccines among Iranian women of reproductive age. Methods A cross-sectional survey was conducted among vaccinated women who reported their menstrual cycle status before and after each vaccine dose. Data on cycle regularity, flow characteristics, and specific menstrual disorders were collected and analyzed. Results Menstrual cycle alterations were reported by 28.8%, 25.4%, 30.3%, and 68.4% of participants after the first, second, third, and fourth vaccine doses, respectively. The most common changes were oligomenorrhea after the first and second doses (8.9% and 5.6%), menorrhagia after the third dose (5.3%), and hypomenorrhea after the fourth dose (8.3%). Comparisons with international studies revealed a wide variation in prevalence (ranging from 25% to 78%), which may be explained by differences in methodology, population characteristics, vaccine types, and pre-vaccination health status. Conclusion A considerable proportion of Iranian women experienced menstrual alterations following COVID-19 vaccination, most commonly oligomenorrhea, menorrhagia, and hypomenorrhea. While generally self-limiting, these findings highlight the need to integrate menstrual health into post-vaccination monitoring and patient counseling. Future research should explore the underlying immune-endocrine mechanisms and long-term clinical implications of these changes.

Background: Sternal dimensions show population-specific sexual dimorphism and may support forensic identification when more informative skeletal elements are unavailable. Computed tomography (CT) permits non-destructive, reproducible three-dimensional assessment of the sternum. Objective: To quantify sex- and age-associated differences in CT-derived sternal measurements among adults from Western Uttar Pradesh, India. Methods: This prospective cross-sectional study included 250 adults aged 20-80 years (155 males and 95 females) referred for chest CT at a tertiary hospital in Moradabad. Images were acquired using a Philips Ingenuity Core 128-slice scanner with 1-mm sections and 0.5-mm reconstruction increments. Manubrium width (MW), manubrium length (ML), sternal body length (B), corpus sterni widths at the first and third sternebrae (CSWS1 and CSWS3), sternal index (SI), combined length (CL), and sternal area (SA) were evaluated. Independent-samples t tests, one-way analysis of variance with Tukey post hoc testing, and Pearson correlations were used. Results: Mean age was 48.1 years. Males had greater MW (57.3 vs 49.9 mm), ML (45.3 vs 40.4 mm), B (90.2 vs 75.7 mm), CSWS1 (26.1 vs 23.0 mm), CSWS3 (31.6 vs 27.9 mm), CL (135.5 vs 116.1 mm), and SA (5258.3 vs 3880.5 mm; all p < 0.001). SI was greater in females (53.8 vs 50.8; p = 0.009). Across age groups, only MW (p = 0.001) and SA (p = 0.002) differed significantly. Strong correlations were observed for B with CL (r = 0.902), CL with SA (r = 0.895), B with SA (r = 0.869), and MW with SA (r = 0.847; all p < 0.001). Conclusion: CT-derived sternal morphometry demonstrates marked sexual dimorphism in this Western Uttar Pradesh sample, particularly for SA, CL, B, and MW. These reference values provide a basis for population-specific forensic models; however, predictive accuracy cannot be inferred without classifier development and validation.

Background. Guidelines recommend surgery for moderate and severe cervical spondylotic myelopathy (CSM) but support either surgery or nonoperative care for mild disease. How patients weigh the adverse events associated with each pathway is not well characterized. Methods. We conducted a three-arm randomized vignette experiment among United States adults aged 40 years and older recruited through an online research panel. All participants read an identical description of mild CSM and were randomized to one of three scenarios: surgery that improved symptoms, surgery that halted progression without improvement, or nonoperative management with symptom progression. Participants in the surgical scenarios rated 12 possible complications and those in the nonoperative scenario rated 8 progression outcomes. For each item, participants rated how strongly it would influence their decision (0-10) and whether they would still choose the same treatment. Items for which participants would no longer choose the same treatment were termed dominant decision factors. Results. Of 276 respondents, 263 (95.2%) were analyzed. Dominant factor rates ranged from 13.5% to 87.8% across complications. Complications described as persisting at one year produced substantially higher rates than the same complications described as resolving by three months. Adverse events more frequently constituted dominant factors when surgery was framed as offering less benefit, although differences between scenarios were not statistically significant. In the nonoperative scenario, worsening bladder control (56.6%) and neck pain interfering with sleep (53.0%) were the strongest influences, exceeding needing a cane to walk (32.1%). Conclusions. Treatment decisions for mild CSM are driven primarily by the expected permanence of adverse events and their anticipated impact on daily quality of life, rather than by conventional neurological metrics or surgical benefit framing.

Background: Early defibrillation is a key factor of survival following out of hospital cardiac arrest (OHCA). In the United Kingdom, initial anterior lateral (AL) defibrillator pad placement is standard practice. However, anterior posterior (AP) pad positioning has been proposed as a method of improving current flow through the myocardium particularly in cases of refractory ventricular fibrillation (VF). Concerns remain regarding potential delays to defibrillation associated with alternative pad placement strategies and the practical application of AP positioning. Objective: We conducted two consecutive simulation studies to explore whether there is a difference in the time taken to apply defibrillator pads, and placement accuracy, between AP and AL positions during simulated OHCA. Methods: This research study comprised of two simulation studies. First, we evaluated pad placement accuracy before and after written instruction showing optimal pad placement (RESTART SIM accuracy). Second, we undertook a randomised crossover examining time to pad placement, timing to successful pad application was recorded for each attempt (RESTART SIM speed). Results: RESTART SIM (accuracy) out of 14 participants 50% correctly placed AL pads and 14% correctly placed AP pads initially. Following provision of guidance this increased to 93% for AL but remained at 14% for AP placement. 9 participants completed RESTART SIM (speed). Mean AP pad placement time was 14.2 seconds and standard deviation of 2.64, compared with 10.6 seconds for AL placement and a standard deviation of 4.24. AP first strategy mean placement time was 15.3 seconds and mean AL placement time was 11.5 seconds. In AL first mean AP placement time was 12.8 seconds and mean AL placement time was 9.6 seconds. Conclusion: AP pad placement whilst slower than AL placement the time difference of 4 seconds is unlikely to be clinically significant. However, without guidance, both AL and AP placements were often inaccurate. After a guidance picture AL placement was increased but AP remained poorly placed.

Structural musculoskeletal pain, defined as pain associated with musculoskeletal conditions of the spine and peripheral joints, afflicts persons widely, independent of demographic, and continues to contribute substantially to disability on a global scale. Osteopathic manipulative treatment (OMT) is a non-invasive therapy performed by osteopathic physicians, encompassing a wide variety of techniques meant to heal the dysfunctions manifesting structural musculoskeletal pain. However, the efficacy of OMT in relieving pain symptomatology remains subject to debate. This meta-analysis examines the effect OMT serves to manage structural musculoskeletal pain, measured on a Visual Analog Scale. Three randomized control studies (RCTs) were included, with a total of 231 participants, 117 of which received OMT as part of pain management treatment, the other 114 receiving other treatment modalities. Using the random effects model, the mean difference between OMT and non-OMT treated groups was -1.80 (-7.31; 3.78). Although this mean difference favors OMT with regard to greater reduction in pain, the finding is not statistically significant. Heterogeneity was found to be extraordinarily high (I2 = 96%) and statistically significant (p = <0.0001), albeit attributed to one of the papers, deemed an outlier. With its removal, heterogeneity was still moderate (I2 = 54.4%). Given these findings, the efficacy of OMT in reducing structural musculoskeletal pain cannot be proven. A significant limitation of this study was a low sample size, consisting of 3 RCTs, reducing statistical power. In addition, there was high heterogeneity between studies. More high-quality RCTs with larger sample sizes, standardized methods, and an examination of a broader set of structural musculoskeletal conditions are necessitated to better evaluate the contribution of OMT in pain reduction.

Purpose To determine the frequency of echocardiographic abnormalities in women with preeclampsia with severe features. To describe the spectrum and types of echocardiographic abnormalities associated with preeclampsia with severe features. Method This is a Prospective observational study conducted in Vani Vilas hospital attached to Bangalore Medical College and Research Institute, Bangalore from January 2023 to December 2025. 560 pregnant women diagnosed with severe preeclampsia(SPE) were included in the study. Chronic hypertension without superimposed preeclampsia, underlying cardiac diseases and previous history of peripartum cardiomyopathy were excluded from the study. Transthoracic echocardiography-TTE (2D ECHO) was done to evaluate cardiac structure and function. Echocardiographic abnormalities identified during the study were documented and analysed using descriptive statistical methods. Results Abnormalities in ECHO was noted in 23.03%. A unique finding was the documentation of elevated pulmonary artery systolic pressures (PASP) suggestive of Pulmonary Hypertension (PH) (PASP >35 mm HG) among 20.25% of the participants. It was also the commonest abnormality on ECHO. Mild PH was the commonest (15.71%), moderate PH was seen in 3.92% and severe PH in 0.71% of cases. Next most frequent abnormality was moderate to severe valvular regurgitation (10%), followed by left ventricular hypertrophy (5.53%). Diastolic dysfunction (DD) was seen in 3.92%, systolic dysfunction(SD) in 3.57%, chamber dilatation in 3.57% and LV global hypokinesia in 3.03% cases of SPE Conclusion Preeclampsia with severe features (SPE) is associated with 23.03% abnormalities on echocardiography. SPE is associated with systolic dysfunction, diastolic dysfunction, chamber dilatation, valvular regurgitation, left ventricular hypertrophy and pulmonary hypertension.

Vertebral artery stenosis is a condition amenable to treatment with stenting. To accurately size stents, angiography is the most used imaging technique despite its limitation as a lumenogram with few planes of imagery. The technique's deficiencies are especially apparent at the vertebral artery origin due to image obstruction by surrounding vessels as well as vessel tortuosity. By contrast, intravascular ultrasound (IVUS) can be used to measure the arterial external elastic lamina (EEL), which is closer to the true vessel size and often leads to larger and more appropriate stent sizes being chosen for more effective treatment. A retrospective measurement comparison study was conducted on eight patients with vertebral artery stenosis. 2D digital subtraction angiography (2D DSA) and IVUS images were taken along the vertebral artery for each patient, and the blood vessel diameter was measured using the two techniques along a continuous segment of the artery. Our results indicated a statistically significant discrepancy between the diameter measurements (p<0.05), with EEL measurements by IVUS showing a mean percent increase of 32.96%, or 1.19 mm, compared to 2D DSA lumen measurements. The significant measurement contrast between the two techniques can lead to smaller stent sizes being chosen, increasing the risk of restenosis and stent thrombosis due to malapposition. Sizing stents to the EEL is possible with IVUS imaging and can lead to more reliable treatment due to more secure strut placement on the tunica intima and a more complete expansion of the artery.

Background Cervical spondylotic myelopathy (CSM) is the most common cause of nontraumatic spinal cord dysfunction in adults. For mild disease, guidelines recommend shared decision-making between surgery and structured rehabilitation on the basis of clinical equipoise, yet no comparative effectiveness study has reported outcomes in this population. Whether a randomized trial is feasible is unknown. Methods We conducted two cross-sectional surveys between December 2025 and July 2026: one of patients with surgeon-confirmed CSM recruited from academic outpatient spine clinics, and one of practicing neurosurgical and orthopedic spine surgeons. Respondents rated willingness to participate in (1) a randomized trial of early surgery versus observation and (2) a prospective observational study in which treatment was patient-selected. Responses of likely or very likely were classified as willing. Groups were compared using Fisher exact tests, designs within respondents using exact McNemar tests, and predictors using univariable logistic regression. Results Fifty-four patients and 52 surgeons completed the surveys. Patients were markedly less willing than surgeons to accept randomization (15 of 54, 27.8% versus 44 of 52, 84.6%; p < 0.001). Both groups accepted the observational design (39 of 54, 72.2% versus 51 of 52, 98.1%; p < 0.001), and 26 of 39 patients unwilling to be randomized were willing to enroll in an observational study (p < 0.001). Willingness to be randomized did not differ across mJOA severity (mild 30.4%, moderate 25.0%, severe 27.3%; p = 0.93). Among patients declining randomization, 85.2% cited a wish to retain control over treatment, whereas fear of surgery was cited by one respondent. Forty-five surgeons (86.5%) considered both surgery and observation reasonable, and preference was divided (46.2% favoring early surgery, 48.1% favoring initial observation). Conclusions Surgeons report equipoise and high willingness to randomize, but most patients would decline random allocation, citing a wish to retain treatment choice rather than fear or distrust. A prospective observational study appears the more feasible route to comparative evidence in mild CSM. Feasibility assessments restricted to clinicians may substantially overestimate attainable accrual.

Abstract Introduction In-hospital cardiac arrest carries high mortality despite standardized ACLS training. Educators face increasing time constraints in developing assessment tools for ACLS training. Two possible solutions to this problem are using pre-medical students or using artificial intelligence to generate test questions. This study compared the quality of pre-medical student-generated ACLS test questions vs. AI-generated ACLS test questions, testing the hypothesis that AI-generated questions are non-inferior to student-generated questions. Methods Ten pre-medical students created ACLS questions following predefined criteria, while an AI model (Northwell's Artificial Intelligence Hub) generated comparable questions. A blinded ACLS-certified physician evaluated questions on the qualities of Alignment, Clarity, Cognitive Level, and Question Design using a standardized rubric (Likert scale: 1 = poor quality, 5 = excellent). Student's T-test and Chi-square analysis were used to compare the quality of questions on different rubric domains within each arm (student vs. AI) and within one domain (eg, question Clarity) between arms. The Student's T test was used when 2 comparator groups were compared (eg, Clarity of student-generated vs. AI-generated questions) within one arm. The ANOVA test was used when comparing more than 2 comparator groups (eg, Alignment vs. Clarity vs. Cognitive Level) within one arm. Statistical significance was set as a priority at p <0.05. Results Both student-generated and AI-generated questions were of high quality. AI-generated questions achieved the maximum score in the domains of Alignment, Clarity, and Question Design, but fell short of perfect scores in the domain of Cognitive Level (8 of 50 questions were less than 5). Student-generated questions achieved less-than-perfect scores in each domain. No significant difference was found in overall mean question scores between groups (students = 4.79, AI = 4.81; p = 0.9). However, AI-generated questions had significantly-greater Clarity (students = 4.8, AI = 5; p = .0461), while Alignment, Cognitive level, and Question Design showed no significant differences. Conclusion AI-generated questions demonstrated overall quality comparable to those generated by pre-medical students, supporting the potential role of AI as a scalable tool in ACLS educational assessment development. Further studies are warranted to evaluate additional AI platforms and determine optimal integration of AI in medical education assessment design.

Abstract Aim: Low chemotherapy response is a major risk factor for early mortality in cancer patients; it is one of the biggest challenges in cancer treatment. Main aim of this study is to identify chemotherapy non-responder, prognostic significance of pre-chemotherapy baseline variables in survival, distinguish most effective anti-cancer drug classes and formulation. Methods: In this multi-center retrospective cohort (n=2459) patients deceased with NSCLC and received anti-cancer drugs were included for analyses. To identify chemotherapy non-responder, patient population was divided into three sub-groups based on chemotherapy prescription frequency [1-15] as group-A, [16-30] as group-B, and [[&ge;]31] as group-C. Multivariate analysis was performed to identify risk of 1-year mortality in these groups. To prognose chemotherapy response in resected and unresected NSCLC patients, 0-7 days pre-chemotherapy white blood cell (WBC) count total five-ranges were compared as per overall survival in abnormal Vs normal WBC counts. Results: Post-stratification in group-A there were (n=1289) patients, in group-B (n=648) patients, and in group-C (n=522) patients. In group-A (n=301) patients 23% were found to have no new metastasis post-diagnosis significantly less p-value (0.004) compared to Group-B (n=125) 19.3%, and group-C (n=110) 19.2% patients p-value (0.008). Metastasis during chemotherapy was found significantly less in 20% patients of group-A, compared to (33%) in group-B, and (43%) in group-C p-value (<0.001). Post-chemotherapy initiation OS in group-A patients were significantly less 9 months (95% CI 9.3 - 9.6) compared to group-B 19 months (95% CI 17.7 - 20.2) and group-C 36.6 months (95% CI 34.6 - 38.5) patients p-value (<0.0001). Despite of low new metastasis and post chemo metastasis, group-A patients survived significantly less based on these outcomes group-A patients were considered as chemotherapy non-responder. Males and NSCLC stage III/IV patients were at higher risk; clinical benefits are corelated to surgery and radiotherapy for chemotherapy non-responder. Leukocytosis in both resected/unresected NSCLC group-A (13%) patients were found to be bad prognostic factor of survival in unresected group-B (5%) patients. Oral formulation of receptor tyrosine kinase inhibitors (RTKI) was effective in non-responders. Conclusion: Stratification of patient population based on chemotherapy prescriptions could be a useful method to find chemotherapy response in retrospective analysis. Patients with pre-chemotherapy leukocytosis should be closely monitored prior to selection of chemotherapy dose and formulation.

Abstract Objective: Glaucoma is a chronic disorder that impairs ocular health and may exacerbate ocular surface disease leading to tear film instability, dry eye symptoms and decreased quality of life. This study compared changes in tear quantity among glaucoma subjects living with and without diabetes mellitus, attending an eye clinic in Nigeria. Methods: A comparative cross sectional research design was used. 157 subjects which comprised 74 glaucoma subjects living with diabetes mellitus and 83 glaucoma subjects living without diabetes mellitus participated in the study. Tear quantity assessment included the Schirmer I test and tear meniscus height (TMH) measurement. Descriptive statistics, independent samples t-test and Chi-square test were used to examine the data at 0.05 level of significance. Results: Glaucoma subjects living with diabetes mellitus showed substantially decreased tear production (11.4 +/- 6.8 mm) compared with glaucoma subjects living without diabetes mellitus (19.6 +/- 9.6 mm; p < 0.001). Tear meniscus height in glaucoma subjects living with diabetes mellitus (0.8 +/- 0.3 mm) was significantly greater than in subjects living without diabetes mellitus (0.7 +/- 0.3 mm; p = 0.034). Conclusion: Diabetes mellitus dramatically deteriorates the ocular surface function in glaucoma subjects by decreasing tear production, altering the tear meniscus height and increasing the severity of ocular surface symptoms. Routine glaucoma care, especially in patients with diabetes mellitus, should include a full ocular surface evaluation including Schirmer I test, TBUT, TMH, and OSDI assessment to allow early detection and management of ocular surface disease, better treatment adherence, and improved visual outcomes. Keywords: Glaucoma, Diabetes Mellitus, Tear production, Tear Meniscus Height, Ocular Surface Disease.

Background: Diabetes mellitus and hypertension are increasingly prevalent non-communicable diseases that often coexist due to their interrelated pathophysiology and commonalities of risk factors. Effective management of these two comorbid conditions often involves polypharmacy, defined as the concurrent use of five or more medications, which for therapeutically relevant outcomes requires a high-medication adherence. Limited data exist on the extent of polypharmacy and its impact on adherence among Tanzanian patients with these comorbidities. This study therefore aimed at evaluating the prevalence of polypharmacy and its impact on medication adherence levels among this population. Methodology: A cross-sectional study involving 396 outpatients was conducted at Muhimbili National Hospital. Consecutive sampling was used to recruit eligible participants. Data was collected using structured-questionnaire which captured information on socio-demographics, clinical characteristics and adherence behaviors. Polypharmacy was defined as using five or more medications. Medication adherence was assessed using the Medication Adherence Report Scale (MARS-5). Multivariable logistic regression was performed to identify factors associated with adherence. Results: 71% of the study participants were on five or more medications, indicating high polypharmacy prevalence, with a median of six medications. Medication adherence was reported at 55.1%. Factors associated with lower adherence included moderate (APR: 0.83, P = 0.001) and high fasting glucose (APR: 0.66, P < 0.001), herbal medicine use (APR: 0.72, P < 0.001), and uncontrolled blood pressure. Conclusion: This study reveals a high prevalence of polypharmacy with moderate medication adherence among patients with comorbid T2DM and hypertension. These findings suggest a targeted intervention utilizing such as patient education and medication reviews are essential to improve adherence and management in Tanzania.

Introduction: Polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS), is a common endocrine disorder affecting women of reproductive age. Besides reproductive and metabolic disturbances, PMOS negatively impacts psychological well-being and quality of life. Despite available treatment options, there remains a need for safe and effective therapies that improve both clinical symptoms and fertility outcomes. Aim: To compare the efficacy of VAMHA and MYRHA tablet combination therapy with standard non-hormonal therapy in restoring regular menstruation. Secondary objectives included assessment of ovulation, menstrual symptoms, polycystic ovarian morphology, hormonal and metabolic parameters, anthropometric measures, and skin manifestations. Study Design: Open-label, randomized, multicentre, prospective comparative clinical study. Methods: Seventy-one women with PMOS were randomized to Group A (n=37) or Group B (n=34). Group A received VAMHA and MYRHA tablets (2 tablets each), while Group B received Metformin 500 mg plus Myoinositol 600 mg (1 tablet), twice daily for 180 days. Data were recorded in Case Report Forms. Statistical Analysis: Continuous variables were summarized using mean and standard deviation, while categorical variables were expressed as frequencies and percentages. Appropriate statistical tests, including Chi-square, were used. A p-value [&le;]0.05 was considered significant. Results: Significantly more participants in Group A achieved regular menstrual cycles than Group B (31 vs. 22; p<0.05). Ovulation occurred in 16 participants in Group A compared with 6 in Group B (p<0.05). Both groups showed significant improvement in menstrual irregularity and related symptoms. Significant reductions in Anti-Mullerian Hormone (AMH), fasting insulin, and body mass index (BMI) were observed in both groups (p<0.05). Resolution of polycystic ovarian morphology occurred in 13 participants (38.23%) in Group A and 10 (33.33%) in Group B. Both treatments were well tolerated with no major safety concerns. Conclusions: VAMHA and MYRHA combination therapy was superior to standard non-hormonal therapy in improving menstrual regularity and ovulation. It also produced favourable metabolic, hormonal, and ultrasonographic outcomes, suggesting its potential as a safe and effective option for comprehensive PMOS management and fertility enhancement.
