The left axillary artery is a reasonable option as the inflow site for saphenous vein graft in minimally invasive coronary artery bypass grafting.

Introduction: This study aims to clarify the good inflow site for saphenous vein grafts (SVG) in minimally invasive off-pump coronary artery bypass grafting (mini-CABG), between the ascending aorta, the internal thoracic arteries (ITAs) and the left axillary artery (LAA). Methods: This retrospective study included 126 patients who underwent Mini-CABG at our center between January 2014 and July 2023. Patients were divided into three groups according to the SVG inflow site for patency comparison: Aorta group (n = 56), LAA group (n = 23), and ITA group (n = 47). Results: There were 84 males, with mean age of 65.9 ± 7.0 years. There were no significant differences in preoperative characteristics between groups. Mean operation times were 254.6 ± 72.2, 213.7 ± 57.6, and 253.0 ± 81.2 min, and the average numbers of distal anastomoses were 2.9 ± 0.9, 2.4 ± 0.7 and 2.9 ± 1.1 in the Aorta, ITA and LAA groups respectively. Days in intensive care, hospital stay, and major complications did not differ between the groups. Early patency of SVG did not significantly differ among groups: 93.0% in the Aorta group, 98.0% in the ITA group, and 100% in the LAA group. Mean follow-up period was 136.7 ± 295.7 days, and follow-up coronary CTA revealed 18 SVG occlusions (Aorta group n = 8, ITA group n = 5, LAA group n = 5). The Kaplan-Meier curve for SVG patency rates did not show any significant differences among the three groups. Conclusion: The ascending aorta, the ITAs, and the LAA serve as reliable inflow sites with similar results in mini-CABG.

Development of clinical prediction model to guide the use of CT head scans for non-traumatic Thai patient with seizure: A cross-sectional study.

The aim of this study was to develop clinical predictor tools for guiding the use of computed tomography (CT) head scans in non-traumatic Thai patients presented with seizure. A prediction model using a retrospective cross-sectional design was conducted. We recruited adult patients (aged ≥ 18 years) who had been diagnosed with seizures by their physicians and had undergone CT head scans for further investigation. Positive CT head defined as the presence of any new lesion that related to the patient's presented seizure officially reported by radiologist. A total of 9 candidate predictors were preselected. The prediction model was developed using a full multivariable logistic regression with backward stepwise elimination. We evaluated the model's predictive performance in terms of its discriminative ability and calibration via AuROC and calibration plot. The application was then constructed based on final model. A total of 362 patients were included into the analysis which comprising of 71 patients with positive CT head findings and 291 patients with normal results. Six final predictors were identified including: Glasgow coma scale, the presence of focal neurological deficit, history of malignancy, history of CVA, Epilepsy, and the presence of alcohol withdrawal symptom. In terms of discriminative ability, the final model demonstrated excellent performance (AuROC of 0.82 (95% CI: 0.76-0.87)). The calibration plot illustrated a good agreement between observed and predicted risks. This prediction model offers a reliable tool for effectively reduce unnecessary use and instill confidence in supporting physicians in determining the need for CT head scans in non-traumatic patients with seizures.

Multi-vessel coronary artery grafting: analyzing the minimally invasive approach and its safety.

Introduction: At our institution, we perform off-pump coronary artery bypass (OPCAB) as a standard procedure. Moreover, patients with favorable coronary anatomy and condition are selected for minimally invasive cardiac surgery (MICS)-OPCAB. We retrospectively compared early outcomes, focusing on safety, between MICS-OPCAB and conventional off-pump techniques for multivessel coronary artery bypass grafting (CABG). Methods: From August 2017 to September 2022, 1,220 patients underwent multivessel coronary artery grafting at our institution. They were divided into the MICS-OPCAB group (MICS group = 163 patients) and the conventional OPCAB group (MS group = 1057 patients). Propensity score matching (1 : 1 ratio) was applied to the MICS-OPCAB and MS groups (149 patients per group) based on 23 preoperative clinical characteristics. Results: After matching, there were no significant differences in preoperative characteristics between the groups. The MICS group had a lower total graft number (2.3 ± 0.6 vs. 2.9 ± 0.8, p < 0.001) and fewer distal anastomoses (2.7 ± 0.8 vs. 3.2 ± 0.9, p < 0.001). There were no significant differences in hospital stay, intensive care unit stay, postoperative complications, and 30-day mortality. The MICS group had less drain output (MICS 350 ml [250-500], MS 450 ml [300-550]; p = 0.013). Kaplan-Meier analysis revealed no significant differences in postoperative MACCE (major adverse cardiac or cerebrovascular events)-free and survival rates between the groups (MACCE-free rate p = 0.945, survival rate p = 0.374). Conclusion: With proper patient selection, MICS-OPCAB can provide good short to mid-term results, similar to those of conventional OPCAB.

Assessing the benefits of anaortic off-pump coronary artery bypass grafting.

Introduction: The procedure called the "aorta no-touch" (NT) or anaortic technique in off-pump coronary artery bypass grafting (OPCAB) is designed to reduce the perioperative risk of stroke. We have observed an increased frequency of anaortic OPCAB procedures at our institution. The main purpose of the present study is to investigate the effectiveness of anaortic OPCAB in reducing the perioperative risk of stroke. Methods: From April 2011 to July 2023, a total of 2,236 patients underwent isolated OPCAB at our single center. The patients were divided into the anaortic group (NT, n = 762) and the aortic group (A, n = 1,474). The NT group was propensity score-matched (PSM) with the A group at a 1:1 ratio (NT n = 640; A n = 640), and matching was performed based on 26 covariates with preoperative clinical characteristics. Results: In both the unmatched and matched cohorts of the NT and A groups, there were no significant differences observed in new stroke rates (NT vs. A; unmatched, 1.0% vs. 1.2%, p = 0.624; matched, 0.9% vs. 1.3%, p = 0.789). The univariable logistic analysis did not identify the anaortic technique as an independent factor negatively associated with new stroke events (OR = 0.81, 95% CI = 0.35-1.86, p = 0.624). Conclusion: The present study did not find the anaortic technique to reduce the perioperative risk of stroke in OPCAB. Hence, further large studies are needed to identify patient cohorts in which anaortic OPCAB is significantly beneficial.

The efficacy of induction treatment in Thai patients with lupus nephritis: Observational cohort analysis.

BACKGROUND: For active proliferative lupus nephritis (LN), intravenous cyclophosphamide (IVCYC) is a standard therapy whereby mycophenolate mofetil (MMF) is less effective than IVCYC, according to the clinical trials in non-Asians. In this observational study, the clinical outcomes will be compared among Thai patients. METHODS: We had analyzed 93 adult patients who underwent a renal biopsy for active proliferative LN confirmation between January 2013 and June 2021. The assessment of the response outcomes compared the induction treatment of IVCYC versus MMF. The primary endpoint had achieved complete remission (CR) at 24 weeks, while the secondary endpoint is overall remission (OR) and urine protein creatinine ratio (UPCR) changed over time. RESULTS: 93 LN patients were separated into two groups; 40 in IVCYC and 53 in MMF. In the 24th week, based on unadjusted analysis, patient had achieved CR 20.0% of IVCYC, whereas 28.3% of MMF had achieved CR. Unadjusted CR Risk difference was -0.08 (95% CI -0.26, -0.09, p-value = 0.351) and the adjusted CR risk difference was -0.19 (95% CI -0.42, 0.04, p-value = 0.098). The unadjusted OR risk difference was -0.06 (95% CI -0.26, 0.14, p-value = 0.553) while adjusted OR risk difference was -0.24 (95% CI -0.50, 0.02, p-value = 0.067). Unadjusted UPCR mean was -0.29 (95% CI -0.77, 0.17, p-value = 0.210) and adjusted UPCR mean was -0.27 (95% CI -0.88, 0.32, p-value = 0.366). CONCLUSIONS: The induction treatment with either IVCYC or MMF had similar efficacy in Thai LN patients. The decision of treatment should be taken by applying an individualized therapeutic strategy and balancing risks, costs, and benefits.

Prevalence and Associated Factors of Depression in Medical Students in a Northern Thailand University: A Cross-Sectional Study.

This study was conducted to investigate the prevalence and associated factors of depression in medical students. This cross-sectional study investigated the prevalence and associated factors of depression in medical students from May 2018 to April 2019. Depression was diagnosed using the nine-item Patient Health Questionnaire. We evaluated the following potential predictors: demographic data, stressors, psychiatric comorbidities, emotional intelligence (EI), and perceived social support. The association between potential factors and depression was analyzed using multiple logistic regression analysis. The prevalence of depression was 149 of 706 students with 12.5% suicidality. Second- and fourth-year medical students were high-risk groups. Risk factors identified were insufficient income, physical illness, and previous psychiatric illness. Depression in medical students likely coincides with anxiety, internet addiction, sleep problems, and loneliness. Highly associated stressors were personal relationships, physical health, mental health, difficulties in social relationships, satisfaction with grades, and boredom with medical education. Protective EI factors included emotional self-control, problem-solving abilities, inner peace, and life satisfaction. Up to 21.1% of medical students had depression. In this study, among multiple known risk factors of depression, we found that EI is the novel protective factor against depression among medical students. EI training might be protective intervention for medical students in the future.
