AIM： To analyze the Hepatitis C virus （HCV） genotype distribution and transmission risk factors in a population of unselected patients in Luxembourg.METHODS： Epidemiological information （gender, age and transmission risks） were collected from 802 patients newly diagnosed for hepatitis C and living in Luxembourg, among whom 228 patients referred from prison. Genotyping using 5＇noncoding （5＇NC） sequencing was performed. We compared categorical data using the Fisher＇s exact F-test and odds ratios （OR） were calculated for evaluating association of HCV genotype and risk factors.RESULTS： The sex ratio was predominantly male （2.2） and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant （53.4%） followed by genotype 3 （33%）. Among risk factors, intravenous drug usage （IVDU） was the most frequently reported （71.4%） followed by medical-related transmission （17.6%） including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU （OR = 4.84, P 〈 0.0001） whereas genotype 1 was significantly associated with a medical procedure （OR = 2.42, P 〈 0.001）. The HCV genotype distribution from inmate patients differed significantly from the rest of the population （Chi-square test with four degrees of freedom, P 〈 0.0001） with a higher frequency of genotype 3 （46.5% vs 27.5%） and a lower frequency of genotype 1 and 4 （44.7% vs 56.8% and 5.3% vs 9.6%, respectively）. IVDU was nearly exclusively reported as a risk factor in prison.CONCLUSION： We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European counties, with one of the highest European prevalence rates of genotype 3 （33%）. Since serology screening became available in 2992, IVDU remains the most common way of HCV transmission in Luxembourg.

Background: A selective inhibitor of sodium-glucose cotransporter 2 (SGLT2), empagliflozin, has demonstrated its effects in reducing cardiovascular mortality and hospitalization rates for heart failure in type 2 diabetes patients. However, the cardiac-intrinsic mechanism for this cardiovascular benefit has not been sufficiently studied. We therefore aimed to investigate the effect of empagliflozin on left ventricular function in a group of patients with grade I hypertension. Methods: We carried out a single-arm non-randomized clinical trial at the National Obesity Centre in Yaoundé over a period of 8 months (October 2016 to May 2017), where patients were assigned to receive 25 mg of empagliflozin once daily. Cardiac ultrasound, 24-hour ambulatory blood pressure measurement, resting electrocardiography and biological assessment were carried out at baseline and at the end of a 6-week treatment period with empagliflozin. The primary outcome was the improvement of the left ventricular relaxation evaluation criteria. Ethical approval was obtained from the Centre Regional Ethics Committee in Yaoundé, Cameroon. Results: A total of 11 patients were treated (median observation time, 6 weeks). We noted a non-significant improvement in the early lateral annular velocity from 9.7 [9.2 -

The academic literature has focused more on the competitive performance of retail brands than on their commercial performance per se and its *** research study examines the factors that impact commercial performance by addressing two questions:does the commercial performance of a cosmetic retail brand depend on the country in which it operates(where I am?)or does it depend on the nature of the circuit(who I am?).Finally,our explanatory model of the penetration and market share comprises four factors:the type of store,the geographical area,the percentage of stores owned by the brand,and the time elapsed since the launch of the *** choice of these factors is relevant as evidenced by the strong predictive validity and explanatory power of the *** model reveals a significant effect of the factors and their interactions.
