Studies have reported an association between these deaths with hyperhomocysteinemia. The aim of this study was to compare serum homocysteine levels in middle-aged patients with coronary artery disease. This cross-sectional study was conducted among 52 cardiology inpatients of Bangabandhu Sheikh Mujib Medical University, Dhaka, from March 2021 to February 2022. Among them, 26 were young adults (<40 years, Group I), and 26 were middle-aged (≥40 years, Group II). Serum homocysteine was measured in all of them using an automated immunoassay analyzer. The younger patients had higher (P=0.001) median homocysteine (interquartile range) level, 13.5 (7.7 –28.4 mmol/L) compared to the middle-aged group, 10.0 (5.9 – 38.5 mmol/L). The hyperhomocysteinemia (>15 mmol/L) was 16.2% in Group I compared to 12.4% in Group II (P=0.001). Therefore, control measures for keeping homocysteine levels within the normal range in young people might be useful.\u0000BSMMU J 2022; 15(3): 197-200","PeriodicalId":8681,"journal":{"name":"Bangabandhu Sheikh Mujib Medical University Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41402525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AMH may help in the diagnosis of sonographically inconclusive cases of PCOS. This study measured the AMH level in PCOS to assess its impacts on the diagnosis of the syndrome. This cross-sectional study included 160 newly diagnosed females with PCOS who were diagnosed using a modified revised Rotterdam criteria. Fasting blood was collected to measure AMH by enzyme-linked immunosorbent assay and other hormones [total testosterone, luteinizing hormone and follicle-stimulating hormone] were measured by chemiluminescent microparticle immunoassay. Ovarian USG was done in the follicular phase of the menstrual cycle. Serum AMH≥ 3.5 ng/mL and ovarian volume >10 mL was considered as a combined marker of polycystic ovary (PCO). USG-PCO criteria could detect 84.38% PCO, whereas AMH-PCO criteria 67.5%. There was a lack of agreement between USG-PCO and AMH-PCO criteria [κ=-0.004] in PCOS. AMH-PCO criteria identified 68% of PCO patients undiagnosed by USG-PCO criteria [17/25]. Age [β=-0.172, p=0.040], systolic [β =-0.213, p=0.037] and diastolic blood pressure [β=0.301, p=0.004] had significant predictive associations with AMH by linear regression. AMH had a fair discriminating index for combined-PCO [AUC=0.824] in PCOS patients. In conclusion, AMH assessment can help detect PCOS patients who are inconclusively diagnosed by USG-PCO criteria.\u0000BSMMU J 2022; 15(2): 65-69","PeriodicalId":8681,"journal":{"name":"Bangabandhu Sheikh Mujib Medical University Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41843680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to examine the effect of vitamin D supplementation on insulin resistance, glycemic status, and inflammation in prediabetic adults with vitamin D deficiency. This doubleblind randomized placebo-controlled trial was done among 27 newly detected prediabetic adults with hypovitaminosis D randomly assigned to 60,000 IU of vitamin D weekly for eight weeks followed by monthly for the next four months or placebo along with lifestyle modification in both groups [vitamin D (n= 14) vs. Placebo (n=13).

Glycemic status, fasting plasma glucose (FPG) and Hemoglobin A1C (HbA1C), insulin resistance (homeostasis model assessment of insulin resistance (HOMA-IR) and inflammatory marker high sensitivity C reactive protein (hs-CRP) were measured at baseline and after six months of intervention. Vitamin D levels (ng/mL) increased in both groups from baseline (vitamin D vs. placebo: 12.2±5.9 vs. 3.9±3.5, mean±SD). FPG (mmol/L) significantly decreased in the Vitamin D group (before vs. after: 5.9±0.6 vs. 5.5±0.7, P=0.016, mean±SD), whereas HbA1C (%) and hs- CRP (mg/L) significantly increased in the placebo group (before vs. after- HbA1C: 5.8±0.3 vs. 6.0±0.4, P<0.001; hs-CRP: 5.0±4.4 vs. 5.6±4.9, P=0.039, mean±SD).

The goal of this study was to assess the effectiveness and toxicity of the cisplatin-capecitabine regimen versus the oxaliplatin-capecitabine regimen in treating advanced gastric cancer. Between February 2021 and March 2022, this quasi-experimental study was conducted on 64 advanced gastric cancer patients. Purposive sampling was used to include those who met the inclusion criteria and distributed them evenly between the two arms. Arm A got an injection of cisplatin (80 mg/m2 on day 1) with oral capecitabine (1000 mg/m2 b.i.d. on days 1–14), whereas arm B received an injection of oxaliplatin (130 mg/m2 on day 1) plus oral capecitabine (1000 mg/m2 b.i.d. on days 1–14), every 3 weeks for 6 cycles. A final check-up was done at 12 weeks after the treatment. In arm A, 18 (56.2%) patients exhibited partial response compared to 15 (46.9%) in arm B. Stable diseases were also reported in both arms (18.8% in arm A and 21.9% in arm B). There were 8 (25.0%) cases of progressive disease in arm A and 10 (31.2%) cases in Arm B. The median progression-free survival in arms A (5.6 months) was almost similar to arm B (5.9 months). The most prevalent toxicities in both arms were vomiting, diarrhea, anemia, neutropenia, oral mucositis, paresthesia, handfoot syndrome, and renal toxicity. There were no statistically significant variations in outcomes between the two arms.

It is an intra-articular fracture, so the aim of treatment is anatomic reduction, stable fixation and early mobilization. Tension band wiring (TBW) may be a popular and widely practiced method using either single knot or two knots techniques. Now two knots TBW are widely accepted by AO foundation as well as various countries. But single knot technique is commonly practiced in Bangladesh. The present study was done to see the clinical, radiologi- cal and functional outcome of two knots Tension band wiring (TBW) in Mayo type IIA olecranon fracture. This observational study was carried out by the National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh. A total of 32 patients with Mayo type IIA olecranon fractures were treated with two knots TBW, out of which 30 cases had completed at least 24 weeks of follow-up and analyzed for final functional outcome with Mayo Elbow Performance Score (MEPS). The mean age was 32.58±14.21 years and the male to female ratio was 2.6:1. The mean radiological union time was 8.15±2.25 weeks. In 6 (18.75%) cases, it took 6 weeks, in 18 (56.25%) cases, it took 8 weeks and in 8 (25.0%), it took 12 weeks. Complications were found in 21.9% of patients. At first follow-up after the operation showed that 21 (70.0%) had moderate pain and the final follow-up showed 21 (70.0%) had no pain.

This observational follow-up study was conducted among 20 purposively selected patients who underwent renal allograft transplant surgery from July 2019 to December 2020 in the Department of Urology, BSMMU, Dhaka. Patients with a history of renal transplant recipients or congenital renal anomalies and any urological malignancy were excluded from the study. After kidney transplant, UTI developed in 6 (30%) renal transplant recipients where all were complicated types and occurred between 10 to 14 days postoperatively. UTI was caused by E. coli in 3 (15%) patients, while Klebsiella and Enterococci were causative organisms for 1 (5%) and 2 (10.0%) patients, respectively. SSI developed in 3 (15%) renal transplant recipients where two were superficial, and one was deep. SSI occurred between 5-8 days postoperatively. SSI was caused by S. aureus in 2 (10%) patients and Pseudomonas in 1 (5%) patient. UTI was significantly more in older patients and the patients with a longer duration of catheterization. Older patients and overweight patients had significantly higher rates of SSI. In total, 33% of the recipient during the early hospital stay developed UTIs, all of which were complicated types. SSI developed in 15%, where 2/3rd was superficial and 1/3rd was deep.
