Role of Cod Liver Oil in Preventing Myocardial Infarction.

INTRODUCTION: Omega-3 fatty acids have for long been shown to reduce the incidence of cardiovascular (CV) diseases. Omega-3 fatty acids mainly exist in the form of eicosapentaenoic acid (EPA) and docosahexaenoic acid in fish oils. Cod liver oil is found to have a high concentration of these omega-3 fatty acids. This study aims to explore the benefits of using cod liver oil in reducing the incidence of myocardial infarction (MI) among at-risk patients.  Method: This open-label placebo-controlled two-arm interventional study was conducted in the internal medicine and cardiology unit of tertiary care hospital between January 2018 to January 2021. During this period, 870 patients at risk of CV events were enrolled in the study after obtaining informed consent. The study group received 415 mg cod liver oil daily, in addition to their current treatment, in a bottle without label and the control group received no additional treatment to their standard treatment. Patients were followed up for 12 months or till the development of MI. RESULT: Patients treated with cod liver oil had comparatively fewer incidences of MI; however, the difference was not significant (p-value: 0.09). Furthermore, the difference was non-significant for both fatal and non-fatal MI. The relative risk for total MI incidence was 0.70 (0.44-1.10). CONCLUSION: According to our study, adding cod liver oil to the diet does not play a major role in reducing the risk of MI. Further large-scale studies are needed to understand the role of cod liver oil in reducing the risk of CV events, including MI.

Comparision of Efficacy and Safety of Orlistat vs Placebo in Obese Patients in Pakistan.

Introduction Obesity has become a rising health concern in Pakistan. Several primary measures, such as dietary restrictions and regular exercise, are taken to limit the severe consequences of obesity. Still, such measures alone have been proven to be often short term and therefore, inadequate. In this study, we will evaluate the role of pharmacological management via orlistat in obesity. Methods and Materials A total of 120 patients were enrolled in this study and were divided randomly into two groups (drug arm and placebo arm) of 60 patients each. A standard dose of 120 mg capsules of orlistat given three times a day was administered to the participants of the drug arm group. A placebo was given to the participants in the second group. Baseline investigations were conducted on day 0 of the study, and follow-up visits were planned to take place in week 24 for all participants. Any side effects or adverse events were inquired about and documented in these visits. Results In the orlistat arm, we noted a significant reduction in both body mass index (BMI) (0.04) and waist circumference (0.04). Reduction in weight was more in the orlistat arm than in the placebo arm. However, it is non-significant when compared between day 0 and week 24. Adverse events, such as oily spotting (31.91%), flatus with discharge (27.65%), faecal urgency (25.53%) and fatty stool (35.553%), were significantly higher in the orlistat arm. Conclusion Orlistat has shown positive results in reducing weight, BMI and waist circumference; however, patients should be counselled about potential side effects caused by the mechanism of action of Orlistat.

Maternal characteristics and outcomes affected by hypothyroidism during pregnancy (maternal hypothyroidism on pregnancy outcomes, MHPO-1).

BACKGROUND: Hypothyroidism in pregnancy is an arena of ongoing research, with international conflicts regarding screening, management, and outcomes. Various studies have described the outcomes depending on geographical and international diagnostic criteria. No study has been conducted in this regard from the region of Pakistan. Therefore, we aim to report the clinical features and maternal outcomes of hypothyroid pregnancies and compare the maternal outcomes between uncontrolled and controlled TSH levels in the preconception as well as the gestational period. METHODS: We conducted a cross-sectional retrospective study on 718 cases in the Aga Khan University Hospital after ethical approval. We collected information on pregnant females who have diagnosed hypothyroidism before conception or during their antenatal period. We noted the maternal characteristics and maternal comorbidities. Laboratory data were recorded for thyroid stimulating hormone levels before conception and during gestation. We recorded maternal outcomes as pregnancy loss (including miscarriage, stillbirth/intrauterine death, medical termination of pregnancy and ectopic pregnancy), gestational hypertension, pre-eclampsia, postpartum hemorrhage, placental abruption, and modalities of delivery. Data analysis was performed on Statistical Package for the Social Sciences version 20.0. RESULTS: Among 708 hypothyroid women 638 had live births. Postpartum hemorrhage was the most frequent maternal outcome (38.8%). The emergency cesarean section occurred in 23.4% of cases. We determined TSH levels in 53.2, 56.7, 61.7 and 66.6% of cases in preconception, 1st, 2nd, and 3rd trimester periods. A significant association existed between cesarean section and preconception thyrotropin levels > 2.5 mIU/L, whereas postpartum hemorrhage was significantly associated with thyrotropin levels > 2.5 mIU/L in the preconception and third trimester. CONCLUSION: Successful live births in our patients were complicated by maternal postpartum hemorrhage and a frequent number of emergency cesarean section.
