Abstract
PURPOSE To evaluate the efficacy and safety of a novel technique for removal of migrated esophageal stent (MES) under fluoroscopy. METHODS From January 2009 to April 2023, 793 patients with a dysphagia score of 3-4 underwent esophageal stenting at our center, and 25 patients (mean age: 70.06 years old; male/female: 15/10) underwent stent removal using "loop method" under fluoroscopy. The primary outcomes were technical success and complications. The secondary outcomes were procedure time, radiation exposure, biochemical indicators [white blood cell (WBC), hemoglobin (Hb), platelet (PLT), albumin (ALB), alanine transaminase (ALT), total bilirubin (TB), urea nitrogen (UN) and C-reactive protein] of pre- and post-treatment at 2 weeks. RESULTS Technical success was 100% without major complications. The mean procedure time was (39.44 ± 9.28) minutes, which showed no statistical significance between benign (n = 5) and malignant (n = 20) group [(42.40 ± 8.85) vs (38.71 ± 9.46) mins, p > 0.05]. The mean radiation exposure was (332.88 ± 261.47) mGy, which showed no statistical significance between benign and malignant group [(360.74 ± 231.43) vs (325.92 ± 273.54) mGy, p > 0.05]. Pre- and post-procedure Hb [(114.46 ± 11.96) vs. (117.57 ± 13.12) g/L] and ALB [(42.26 ± 3.39) vs. (44.12 ± 3.77) g/L] showed significant difference (p < 0.05), while WBC, PLT, CRP, and ALT showed no significance (p > 0.05). CONCLUSION Fluoroscopy-guided "Loop method" for MES removal is an effective and safe alternative technique.

Abstract
OBJECTIVES To evaluate the safety and effectiveness of computed tomography (CT)-guided radioactive 125I seeds brachytherapy (RISB) for lung oligometastases (LO) from colorectal cancer (CRC). METHODS Data for 144 LOs from 70 CRC patients who underwent CT-guided RISB were retrospectively analyzed. The primary endpoints were progression-free survival (PFS) and overall survival (OS), and the secondary endpoints were technical success, local control rate (LCR), and complications. Kaplan-Meier method was used for survival analysis. Cox model was used to identify the independent predictors of poor prognosis. RESULTS The RISB procedures were successfully performed in all patients, and the success rate was 100%. The median follow-up was 27.8 months. The median PFS was 10.0 months (95% CI: 8.9-11.1) and the 1- and 2-year PFS rates were 32.9% and 5.9%, respectively. On multivariate analysis, serum carcinoembryonic antigen (CEA) ≤ 15 ng/ml (P = 0.048), middle-high differentiated pathological classification (P = 0.015), primary TNM stages I-III (P = 0.001), LO number ≤ 2 (P < 0.001) and cumulative gross tumor volume (GTV) ≤ 40 cm3 (P < 0.001) showed superior PFS. The median OS was 30.8 months (95% CI: 27.1-34.4) and the 1-, 2-, and 3-year OS rates were 95.7%, 67.4%, and 42.5%, respectively. On multivariate analysis, serum CEA ≤ 15 ng/ml (P = 0.004), middle-high differentiated pathological classification (P < 0.001), primary TNM stages I-III (P < 0.001), LO number ≤ 2 (P < 0.001), cumulative GTV ≤ 40 cm3 (P < 0.001) and system treatments combined with chemotherapy and target therapy (P < 0.001) showed superior OS. The LCR for 3, 6, and 12 months was 97.9%, 91.0%, and 83.6%, respectively. There were 4 cases of pneumothorax at 5.7% that required drainage. CONCLUSIONS RISB for LO from CRC is safe and effective, and serum CEA, TNM stage, LO number, cumulative GTV, and system treatments should be emphasized for long OS.

Abstract
Background The sampling of vascular obstruction diseases remains a challenge in clinical practice. This retrospective study aimed to evaluate the feasibility, accuracy, and safety of intravascular forceps biopsy (IVFB) for the diagnosis of vascular obstructive diseases. Methods From January 2015 to January 2022, of the total of 35 patients who underwent IVFB (21 male, 14 female; mean age 60±11 years; range, 39-81 years), 32 (91.4%) did so during interventional planned revascularization procedures and 3 (8.6%) did so due so due to inaccessible or failed percutaneous access. The outcomes of technical success, biopsy times, patient radiation dose (PRD), complications, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rate (AR) were analyzed. Results The technical success of IVFB was 100%. The median number of biopsies taken per biopsy session and PRD were 4.0 (range, 3-6) and 712.6 mGy (range, 383.4-1,450.8), respectively. The sensitivity, specificity, PPV, NPV, and AR of IVFB were 87.5% (21/24), 100% (11/11), 100% (21/21), 78.6% (11/14), and 91.4% (32/35), respectively. There were no complications related to IVFB. Conclusions IVFB is a technically feasible and safe technique with good diagnostic value. The procedure should be considered in patients who are not suitable for percutaneous access, show indistinct imaging characteristics, or are scheduled to undergo revascularization procedure.

Abstract
Background Cardiovascular diseases (CVDs) are the major cause of morbidity and mortality, particularly in developing countries. Early diagnosis with the best diagnostic marker is highly desired for the prevention and timely treatment of CVDs. However, there is still a dearth of an ideal marker for the detection of CVDs. Objective To explore the diagnostic potential of liver aminotransferases (AST and ALT), and alkaline phosphatase for the diagnosis of CVDs without liver involvement. Method This was a cross-sectional study conducted among 200 adult patients with CVDs, who visited the cardiology and emergency units of Manipal Teaching Hospital, Pokhara, Nepal. The study was conducted from January 2018 to December 2020. The baseline data on family history, anthropometry, baseline biochemical parameters, liver enzymes, and cardiac biomarkers were collected using standard and validated methods. The data were analyzed using SPSS version 21 and MedCalc software 2021. Result The diagnostic sensitivity of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were 53.7%, 52.6%, and 33.7% and specificity were 99%, 90%, and 90% respectively. The area under the curve (AUC) of AST, ALT, and ALP were 0.78, 0.73, and 0.52 respectively. ROC curve indicated that serum AST and ALT activity was a better reliable marker than the serum ALP activities. Conclusion Our study suggests that serum aspartate aminotransferase and alanine aminotransferase but not alkaline phosphatase could have some diagnostic potential to diagnose the risk of CVDs. However, they could not replace the currently adopted cardiac biomarkers such as cTnI and CK-MB.

Abstract
Microalbuminuria is considered to be an early stage of diabetic nephropathy as well as a marker of cardiovascular disease. The aim of this study was to see the prevalence of microalbuminuria in type 2 diabetic patients and assess its association with cardiovascular risk factors among them. A total of 143 type 2 diabetic patients with the mean age of 56.06 +/- 1.08 years were analysed. The prevalence of microalbuminuria and overt proteinuria was 45.5% and 11.2%, respectively. Prevalence of microalbuminuria in female was marginally higher than in male (p > 0.05). Subjects with microalbuminuria had significantly higher blood pressure (p < 0.001) and duration of diabetes (p < 0.05) compared with normoalbuminuric subjects. High density lipoprotein was found to be significantly lower (p < 0.05) in subjects with microalbuminuria whereas fasting blood sugar, triglyceride, total cholesterol and very low density lipoprotein were marginally higher in microalbuminuric than in normoalbuminuric subjects (p > 0.05). High prevalence of microalbuminuria in diabetic patients and its positive association with blood pressure and altered lipid profile suggests that screening for microalbuminuria is essential for intervention and prevent further complications like end stage renal disease and cardiovascular diseases.

Abstract
Drought over Nepal is studied on the basis of precipitation as a key parameter. Using monthly mean precipitation data for a period of 33 years, Standardized Precipitation Index (SPI) is produced for the drought analysis with the time scale of 3 months (SPI-3) and 12 months (SPI-12) as they are applicable for agriculture and hydrological aspects, respectively. Time-space variability is explored based on Principal Component Analysis (PCA) along with Rotated PCA (RPCA). Four rotated components were explored for both SPI-3 and SPI-12 representing climatic variability with cores over eastern, central and western Nepal separately. Droughts associated with SPI-3 occurred almost evenly over these regions. Droughts associated with SPI-12 were consistent with SPI-3 for summer, since summer precipitation dominates annual precipitation. Connection between SPI and the climate indices such as Southern Oscillation Index (SOI) and Indian Ocean Dipole Mode Index (DMI) was studied, suggesting that one of the causes for summer droughts is El Nino, while the winter droughts could be related with positive DMI.

Abstract
Background: The onset of Type 2 diabetes has been associated with low grade systemic inflammation. The inflammatory status has been studied by measuring acute phase reactant proteins like hsCRP, α1- antitrypsin, α1-acid glycoprotein, ceruloplasmin, fibrinogen. Most of these acute phase reactants form α1 and α2 bands on electropherogram of serum proteins. The aim of this study was to evaluate inflammatory status in controlled and uncontrolled type 2 diabetes using cellulose acetate electrophoresis and to find the impact of glycemic status as indicated by HbA1c on inflammation process. Materials and Methods: Serum protein electrophoresis was done on serum samples of 60 cases of Diabetes [controlled and uncontrolled] using cellulose acetate paper technique. The electropherogram obtained was stained with Ponseu S and then quantitated using densitometer. Glycemic status was studied by HbA1c analysis. The density of α1and α2 bands in electropherogram were correlated with HbA1c level. Result: A significant increase in the percentage of α1 and α2 band proteins (0.765 and 0.716, p<0.001) were found with the increasing level of HbA1c. With cutoff of HbA1c 7% (American Diabetic Association recommended), the α1 and α2 serum proteins concentration are significantly higher (p<0.001) in uncontrolled diabetes mellitus compared to controlled diabetes mellitus Conclusion: Cellulose acetate electrophoresis of serum proteins show early phase acute inflammatory status in uncontrolled type 2 diabetes mellitus. The process of systemic inflammation worsens with uncontrolled glycemia as indicated by HbA1c. Inflammatory status should be studied adjunct to glycemic status.
