Background: The Ascertain Dementia 8-item Questionnaire (AD8) is a validated informant-based interview for early dementia detection. Research suggests the utility of self-rated AD8 to identify milder dementia forms in research settings. This study compares the factor structure, reliability, and diagnostic performance between AD8-Self and AD8-Informant for early cognitive impairment (ECI) in a clinical setting. Methods: Five hundreds fifteen patient-informant dyads (43 cognitively intact and 472 ECI) from a tertiary memory clinic completed both self-reported and informant AD8. We conducted exploratory factor analysis to determine the factor structure, Cronbach’s alpha for internal consistency, and receiver operating characteristic (ROC) curve analysis for ECI, including a subgroup analysis for mild cognitive impairment (MCI). Results: The mean age and education of ECI participants were 75.61 years (range, 51–95) and 5.6 years (range, 0–20), respectively, and 72.6 years (range, 51–89) and 6.8 years (range, 0–16) in the MCI subgroup. Unlike AD8-Informant’s one-factor structure, AD8-Self had a two-factor structure corresponding to memory and non-memory domains. AD8-Self demonstrated lower reliability (Cronbach’s alpha: ECI 0.666 vs. 0.764; MCI 0.663 vs. 0.709). In ECI, AD8-Informant (cutoff score ≥3) showed better diagnostic performance (sensitivity 89%, specificity 79%) than AD8-Self (cutoff score ≥4; sensitivity 27.1%, specificity 95.3%) (AUC 0.915 vs. 0.593; p<0.001). Similar results were found in MCI (sensitivity 64.7% vs. 26.5%; specificity 79.1% vs. 95.3%; AUC 0.745 vs. 0.600; p=0.002). Conclusion AD8-Self has a distinct factor structure, lower reliability, and inferior diagnostic performance compared to AD8-Informant for ECI/MCI detection. Our result do not support AD8-Self as a standalone tool for detecting ECI or MCI.

Background: s/Aims: Portal vein embolization (PVE) and Yttrium-90 (Y-90) radioembolization are used to induce liver hypertrophy, increasing future liver remnant volume and reducing the risk of post-resection liver failure. This systematic review compares the effectiveness of PVE and Y-90 radioembolization in promoting liver hypertrophy in patients undergoing liver resection. Methods: A systematic review was conducted in accordance with PRISMA guidelines. PubMed, Embase, Cochrane, and Web of Science were searched for studies published between January 2000 and August 2023. Studies comparing PVE and Y-90 radioembolization with respect to liver hypertrophy were included. Risk of bias was assessed using the Newcastle–Ottawa Scale. Pooled mean differences were calculated using an inverse-variance random-effects model. Results: Of 1,965 studies identified, three retrospective cohort studies met inclusion criteria, comprising 125 patients. Among these, 67.3% underwent PVE and 32.7% received Y-90 radioembolization. Hepatocellular carcinoma was the most common diagnosis (55.9%), followed by metastatic disease (32.3%) and cholangiocarcinoma (11.8%). PVE was more commonly used as a preoperative strategy for liver resection, while Y-90 radioembolization was primarily employed for palliative intent. One study reported greater hypertrophy with Y-90 compared to PVE (63% vs. 36%); however, hypertrophy was assessed over a longer interval (150 vs. 30 days). In pooled analysis, PVE was associated with significantly greater hypertrophy (mean difference 23.75%; 95% CI 12.02–35.48; p < 0.0001; I 2 = 48%). Conclusions Evidence directly comparing PVE and Y-90 radioembolization for liver hypertrophy remains limited. While pooled results favor PVE, procedure selection should be individualized based on clinical context.

Background: s/Aims: Left lateral sectionectomy (LLS) is a commonly performed liver resection. The Rex-recess technique, an extrahepatic Glissonian approach through the umbilical fissure, provides earlier extrahepatic vascular control, potentially resulting in safer and faster resections. However, comparative data between these approaches is limited. This study aims to compare the Rex-recess technique with the standard technique for LLS regarding operative parameters, intraoperative blood loss, and postoperative outcomes. Methods: This retrospective cohort study included 48 consecutive adult patients who underwent open LLS at a tertiary hepatobiliary centre between January 2021 and November 2025. Patients were categorized based on the surgical technique used: standard technique (n = 25) and Rex-recess technique (n = 23). Primary outcomes assessed included operative time, blood loss, transfusion requirements, and postoperative complications. Secondary outcomes focused on selected early postoperative recovery parameters. Results: Baseline demographics were comparable between groups. The Rex-recess technique significantly reduced operative time (90 ± 17.1 minutes vs. 162 ± 27.2 minutes; p < 0.0001) and intraoperative blood loss (80 ± 42.3 mL vs. 250 ± 67.2 mL; p < 0.0001).Other postoperative outcomes, including complication rates and length of hospital stay, were comparable between the two groups. Conclusions The Rex-recess approach appears to be a feasible and anatomically sound technique for LLS, offering advantages in operative efficiency, such as reduced operative time and blood loss. However, due to the retrospective design and non-randomized allocation, these findings should be interpreted with caution. Further prospective studies are needed to validate these results.

Objectives: Catastrophic health expenditures (CHE) is a well-established indicator of financial risk protection. This study aimed to examine the contribution of medication expenditure to CHE and the associated socioeconomic inequalities. Methods: Data were drawn from 6 nationally representative income and expenditure surveys covering the period 2019–2024. Using the budget share method, CHE was defined as out-of-pocket (OOP) health payments exceeding 25% of a household’s total consumption expenditure. The contribution of medication expenditures to CHE was then calculated as the difference in the proportion of households experiencing CHE with and without medication payments. Socioeconomic inequalities were quantified using the Concentration Index (CI), and decomposition analysis was conducted to identify the primary drivers of overall socioeconomic inequality in the contribution of medication expenditures to CHE. Results: During the study period, medications represented a substantial share of household health expenditures and contributed to CHE. In 2024, OOP spending on medications accounted for 31.2% of total health expenditures, while the contribution of medication expenditures to CHE was 1.28%. The CI indicated that the contribution of medication expenditures to CHE was concentrated among poorer households. Decomposition analysis further identified medium-sized households, male-headed households, households with employed heads, insured households, and urban households as the main contributors to this socioeconomic inequality. Conclusions In Iran, OOP payments for medications constitute a substantial share of household healthcare expenditures and contribute to CHE. Because the roots of inequality extend beyond the healthcare system, addressing this issue requires a comprehensive, cross-sectoral strategy that integrates broader social and economic policies.

Purpose: This study evaluated the feasibility and effectiveness of autologous adipose-derived mesenchymal stem cell (ASC) transplantation into the lacrimal gland for treating aqueous-deficient dry eye disease (DED) associated with Sjögren syndrome. Methods: Patients with Sjögren syndrome–related DED underwent autologous adipose tissue harvest via liposuction. ASCs were isolated, cultured, and injected into the lacrimal gland (volume ≤50% of estimated gland volume). Clinical evaluations— including Ocular Surface Disease Index (OSDI), tear osmolarity, tear film breakup time (TBUT), Oxford corneal staining, and Schirmer test I—were conducted at 1-, 4-, 16-, and 24-weeks after injection. Visual quality assessments included contrast sensitivity and higher-order aberrations (HOAs). Results: Six patients (mean age 56.1 ± 7.2 years) completed the study. Mean OSDI scores significantly decreased from 48.6 ± 8.4 to 28 ± 2.1. TBUT improved in both eyes (right, 3.3 ± 1.0 to 5.6 ± 1.2 seconds; left, 3.6 ± 1.0 to 6.1 ± 1.6 seconds). Schirmer test I values increased (right, 4.1 ± 0.7 to 7.8 ± 0.7 mm; left, 4.0 ± 0.6 to 7.6 ± 0.5 mm). Oxford staining scores decreased (right, 1.6 ± 0.5 to 0.67 ± 0.2; left, 1.3 ± 0.5 to 0.67 ± 0.2). Tear osmolarity also improved (right, 311.6 ± 6.1 to 299.1 ± 5.8 mOsm/L; left, 309 ± 7.6 to 298.3 ± 7 mOsm/L). HOAs were reduced in one eye. No significant change in contrast sensitivity or visual acuity was observed. No adverse events were reported. Conclusions Autologous ASC transplantation into the lacrimal gland appears to be a safe and promising therapeutic option for aqueous-deficient DED in Sjögren syndrome, offering significant improvement in both objective measures and patient-reported symptoms over a 6-month period.

Extracranial carotid artery aneurysms (ECAAs) are rare, and the optimal therapeutic modality for these lesions remains controversial. Surgical resection and covered stents may be limited to selected cases. While the concept of using flow diversion is appealing for large aneurysms, the application of flow diverters in extracranial carotid lesions may face restrictions due to off-label use, reimbursement challenges, and factors related to the devices themselves. We report our experience with multiple overlapping Low-profile Visualized Intraluminal Support (LVIS) stents as a reconstructive option for selected ECAAs. Five patients with large ECAAs were treated with multiple overlapping LVIS stents. The primary goal was parent-artery reconstruction and reduction of intra-aneurysmal flow reduction by increasing local metal coverage across the neck of the aneurysm. Double overlapping LVIS stents were used in 3 cases, whereas triple or more extensive overlapping constructs were used in 2 cases. During a mean radiologic follow-up of 24 months, complete occlusion in 2 cases, partial occlusion in 3 cases, and adjunctive procedures in 3 cases were required, and no major thromboembolic or hemorrhagic complications were documented. Adjunctive or staged treatment was required in 3 cases, including balloon angioplasty, additional LVIS stenting, flow-diverter placement, stent-graft placement, or coil embolization. Multiple overlapping LVIS stenting is a feasible and relatively safe reconstructive option for selected large or clinically significant ECAAs, particularly when primary flow-diverter treatment is constrained by off-label indication or reimbursement issues. However, they have limited standalone efficacy, particularly in large or complex aneurysms, often requiring adjunctive or staged treatment.

Background: Access to advanced histomolecular diagnostic testing for central nervous system(CNS) tumors is limited in low and middle-income countries (LMICs), hindering adequate characterization and failure to reach a WHO CNS 2021 diagnosis. LMICs also lack access to targeted therapies, and even conventional chemotherapy and radiation therapies vary between LMICs and high-income countries. Consequently, whether histomolecular subclassification is clinically beneficial and if it provides prognostic information in an LMIC setting is not clear. Here, we address this question by presenting the first systematic prospective study of CNS glioma patients from Pakistan, examining differences in overall survival (OS) by histomolecular subtype. Methods: A total of 194 patients with CNS tumors were enrolled at a single tertiary-care centerin Karachi, Pakistan. Routine histochemical processing, immunohistochemistry, and molecular testing using fluorescence in situ hybridization analysis, limited targeted-panel next-generation sequencing, and polymerase chain reaction were performed to test for isocitrate dehydrogenase (IDH) 1 and 2, P53, ATRX, Ki-67, 1p/19q co-deletion, and MGMT promoter methylation. Results: The results revealed that IDH status was a significant independent prognostic factor,regardless of age (p=0.016), with a 1-year survival rate of 76% and median OS of 16.15 months in IDH-wildtype high-grade gliomas. Conversely, the 1-year survival rate was 95% for IDH-mutant gliomas. Significant survival differences were observed for ATRX status (retained vs. loss) in IDH-mutant gliomas (p=0.046), P53 mutations in IDH-wildtype high-grade gliomas (p=0.05), and 1p/19q co-deletion in grade 3 gliomas (log-rank p=0.023). Conclusion We provide empirical evidence supporting a role for histo-morphological and limitedmolecular testing in neuro-oncology practice in LMICs.

Background: Cerebellopontine angle (CPA) tumors present surgical challenges due to their proxim-ity to the facial nerve. Despite preservation efforts, facial nerve paresis is a major issue. This study aims to identify key factors affecting facial nerve preservation during microsurgical resection of large CPA tumors in a low- and middle-income countries (LMIC) setting. Methods: This retrospective cross-sectional study, conducted at Aga Khan University, includedpatients who underwent microsurgical resection of large (>3 cm) CPA tumors with House-Brackmann (HB) grades 1–4. Postoperative facial nerve function was assessed using the HB grading system. Data was extracted from medical records and analyzed using SPSS 22. Results: This study analyzed 95 patients (M:F=1:1.16, mean age 44.24±13.71 years) withCPA tumors who underwent microsurgical resection. Common presenting complaints included a complete hearing loss (57.9%), headache (52.6%), and abnormal gait (40%). Preoperative facial nerve function was normal (HB grade I) in 75%, with 19%, 7%, and 2% having HB grades II, III, and IV, respectively. Schwannoma (69.5%), meningioma (16.8%), and epidermoid cyst (10.5%) were the most common diagnoses. Postoperative preservation of facial nerve function was achieved in 73.7% of patients. At six months, HB grades I and II were observed in 64% and 11.5%, respectively, while none had complete facial nerve palsy. On univariate analysis, larger tumor size and higher HB grade correlated with worse facial nerve outcomes (p=0.02). Complications were more frequent in patients with worsened outcomes (72% vs. 38.6%, p=0.004). However, in multivariate analysis, only preoperative HB grade was identified as a predictor. Conclusion Facial nerve preservation during CPA tumor resection is influenced by intrinsic tumorcharacteristics, surgical complexity, and patient-specific factors. Detailed preoperative counseling is crucial to set realistic expectations.
