Objective: This study aimed to develop a predictive risk model for post-ablation hemobilia. Methods: This was a retrospective, multicenter, matched case–control study. The case group comprised patients with hepatocellular carcinoma who developed post-ablation hemobilia (n = 21); the control group (n = 63) comprised patients with hepatocellular carcinoma but no post-ablation hemobilia; for each case, we included three controls matched for age, sex, platelet count, year of ablation therapy, and center. Univariate and multivariate regression analyses were performed to identify the risk factors for hemobilia. A risk score model was developed based on adjusted odds ratios (ORs). Results: The independent risk factors for occurrence of post-ablation hemobilia were maximum tumor diameter >47 mm [OR = 5.983, 95% CI (1.134–31.551)] and minimum distance from the applicator to the portal trunk ≤8 mm [OR = 4.821, 95% CI (1.225–18.975)]. The risk model was developed using the adjusted ORs; thus a score of 6 was assigned to the former and a score of 5 for the latter. The area under the curve of this risk model was 0.76. Significant hemodynamic instability and inaccurate embolization might increase the risk of recurrence of hemobilia. Conclusion: Tumor size >47 mm and distance of the applicator from the portal trunk ≤8 mm are independent risk factors for hemobilia. A predictive risk model for post-ablation hemobilia was developed using these risk factors. Advances in knowledge: This is the first study that developed a risk score model of post-ablation hemobilia. Risk factors of the recurrence of post-ablation hemobilia were also been identified.

Aims: Knowing the risk factors for tuberculosis (TB) opens up avenues for identifying target groups for intensified case finding. We aimed to identify the risk factors for pulmonary TB (PTB) incidence in a rural district in northern Ghana. Study Design: A matched case-control study. Place and Duration of Study: The Kassena Nankana West District of the Upper East Region of Ghana, between February 2019 and March 2019. Methodology: This study was conducted in 4 public health facilities. Cases were newly confirmed PTB patients aged 15 years or over, controls were age and sex matched outpatients. A pre-tested questionnaire collected information on a range of possible risk factors from participants. Conditional logistic regression identified independent risk factors for PTB incidence in a multivariable model at 95% confidence level. Results: The analysis included 174 cases and controls. Multivariable analysis showed that the risk of PTB was increased with low household monthly income (AOR=3.45; 95% CI: 1.08-10.97; P=.03), smoking (AOR=2.69; 95% CI: 1.13-6.43; P=.02) as well as household exposure to a known TB case (AOR=2.57; 95% CI: 1.08-6.10; P=.03). Conclusion: Low household monthly income, smoking, and household exposure to a known TB case were independent risk factors for PTB incidence. These factors can be used to actively screen for PTB in the population.

This study was conducted to assess and compare the cardiovascular risk and to explore the demography of CV risk of nonselective cyclooxygenase inhibitors (COX-Is) and selective COX-2-Is in arthritic patients. In this comparative matched case control study adult arthritic patients of either sex taking COX-Is for >1 yr; were included. Arthritic age and sex matched individuals with no history of COX-Is treatment were the controls. Patients those with history of any other disease (e.g. diabetes, hypertension, stroke, IHD etc.) were excluded. Patients were grouped into Control, nonselective COX-I and selective COX-2-I groups. The CV risk factors like blood pressure, blood sugar level(BSL), lipid profile, BMI(body mass index) etc. were assessed and compared; demography of CV risk factors i.e. age, sex, smoking, alcohol, heredity was also studied. Qualitative data was analyzed using Chi-square and quantitative data was analyzed by student’s‘t’-test. Study clearly revealed that all NSAIDs exhibit significant CV risk when taken over a period of time as in arthritis. However selective COX 2-Is found to exhibit more CV risk in this regard. Odds ratio (OR) for CV risk=10.3(95% CI: 1.45, 3.31) and OR for CV risk=5.2(95%CI: 1.05, 2.57) for nonselective COX-Is. BMI, BSL and lipid profile; the potential CV risk factors, showed significant impairment in selective COX 2-Is group; P<0.05, P<0.05 and P<0.01 (HDL), P<0.001 (cholesterol), respectively compared to controls and P<0.05 compared to nonselective COX-Is. This study portrays the potential CV risk of selective COX 2-Is and confirms and re-evaluate the results of earlier studies in this regard.  Keywords: Anti-arthritic agents; BMI; COX-Is; CV risk; Lipid profile.  © 2014 JSR Publications.
