Can laboratory and clinical parameters predict the occurrence of acute arterial occlusion in COVID-19 patients?

Aim To determine radiologic, clinic and laboratory characteristics of COVID-19 positive patients with acute arterial occlusion and compare them with post COVID-19 and non-COVID-19 patients. Methods In this retrospective study, 53 patients with acute occlusion of peripheral arteries admitted to the University Clinical Hospital Mostar in the period between 29 February 2020 and 30 September 2021 were involved. The first group was made of COVID-19 positive patients, the second group were post COVID-19 patients and a control group were non-COVID-19 patients. Results Most patients were males, 37 (69.8%). The average age of COVID positive patients was 66.09±11.25 years, post COVID-19 patients 71.33±5.22 years and COVID-19 negative patients 69.82±1.99 years. Lower extremities were most affected, 38 (71.6%), without significant alteration in the coagulogram. Acute arterial occlusion occurred about 2 weeks after the beginning of COVID-19 or at the time of the first appearance of symptoms. Conclusion We have to take special care about patients with risk factors for developing acute arterial occlusion due to thromboembolism or thrombosis 10 days after the beginning of the disease. We also recommend the use of low molecular weight heparin (LMWH) and monitoring coagulation state due to anti Xa and thromboelastometry.

Effect of n-3 long-chain polyunsaturated fatty acids supplementation in healthy mothers on DHA and EPA profiles in maternal and umbilical blood: a randomized controlled trial.

Background The objective of the study was to compare the effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) dietary supplementation on their concentration in total lipids (TL) and lipid fractions of maternal and umbilical vein (UV) blood. The specific objective was to analyze the impact of EPA and DHA supplementation on pregnancy outcome and neonatal birth weight. Methods Women were randomly single-blinded (randomized controlled trial; ISRCTN36705743) allocated to the group receiving EPA and DHA supplementation (supplemented group) or the group receiving placebo-corn oil (control group) in the time period from January 1st, 2016 until March 1st, 2017. Women in the supplemented group (n=45) took 360 mg EPA and 240 mg DHA daily while controls (n=42) were given a placebo. Maternal and UV bloods were obtained at delivery. After lipid extraction, phospholipids (PL), cholesterol esters (CE), triacylglycerols (TG) and non-esterified fatty acids were separated by thin layer chromatography and analyzed by gas chromatography. Results Higher DHA concentrations in TL (37.24±21.87 mg/L), PL (13.14±8.07 mg/L) and triacylglycerols (2.24±2.21 mg/L) were recorded in mothers from the supplemented group when compared to the study group (TL 21.89±14.53 mg/L; P<0.001; PL 9.33±5.70 mg/L; P=0.013; TG 0.56±0.43 mg/L; P<0.001). Higher DHA concentrations in UV samples were found in TL (11.51±7.34 mg/L), PL (5.29±3.31 mg/L) and triacylglycerols (0.62±0.46 mg/L) from the supplemented groups compared with controls (TL 7.37±3.60 mg/L; P=0.002; PL 3.52±2.19 mg/L; P=0.005; TG 0.40±0.46 mg/L; P=0.035). The ratio of AA:DHA was lower in maternal (2.43) and UV serum (4.0) of the supplemented group than in the control group (maternal 3.85 P<0.001; UV 4.91 P<0.001). Conclusion The study demonstrated the higher ratio of AA/DHA in the control group indicating that pregnant women on the traditional Herzegovina diet need supplementation with DHA and EPA.

Medical students' attitudes towards contraception.

BACKGROUND: The student population is at higher risk of acquiring sexual transmitted diseases (STDs) and accounts for a higher incidence of unplanned pregnancies due to a combination of lifestyle and environmental reasons. AIM: To determine the attitudes of medical students towards contraception. METHODS: A total of 190 students of the School of Medicine of University of Mostar attending four different-academic years participated in this cross-sectional study. Attitudes of participants towards contraception were examined using an anonymous questionnaire. RESULTS: Sexually active students accounted for 61.1% of participants, of which 52.6% regularly used contraception. The most common method of contraception was male condom (90.3%). The main reason for contraception was to avoid pregnancy (64.1%). Students with higher medical education (p<0.001) and students with non-religious views (p=0.004) had positive attitudes towards contraception. There were no gender differences on contraception views. CONCLUSION: Students with higher medical education and those with non-religious views had positive attitudes towards contraception. Therefore, education on contraception assumes its wider use, which is an important measure to reduce the incidence of STDs and unwanted pregnancies in high-risk population.
