Background Hypertension, also referred to as the silent killer, is known to be one of the most common chronic diseases in the world today. This study aimed to identify the prevalence and risk factors of prehypertension and hypertension among Algerian population. Methods This is a descriptive cross-sectional epidemiological study involving individuals aged 18 to 69 years old who were identified in the database of the national survey on non-communicable diseases (NCDs) risk factors conducted in Algeria between 2016 and 2017 using the World Health Organization’s (WHO) STEPwise approach. Differences in prevalence between normotensives, prehypertensives and hypertensives were assessed using the chi-square test. We also looked at the role of numerous socio-demographic, economic, geographical, and behavioural factors in blood pressure status using a logistic regression model. Results The prevalence of prehypertension and hypertension was 36.2% (95% confidence interval: 35.2–37.5%) and 31.6% (95% CI: 30.5–32.7%) respectively. Prehypertension was shown to be substantially higher in males than in women, while hypertension was found to be higher in females compared to men. In addition, both sexes had a rise in the prevalence of blood pressure as they grew older. A according to multivariate logistic regression analysis, the main common risk factors for prehypertension and hypertension were ageing, obesity, and abdominal obesity. Moreover hypercholesterolemia, and marital status (separated/divorced) were correlated to hypertension. Conclusion Prehypertension and hypertension are high and epidemic in Algeria. Therefore, the urgent quantification and monitoring of their risk factors becomes a necessity to plan appropriate preventive measures, in order to fight against NCDs in general.

Background: Recurrent pregnancy loss (RPL) is a common disorder that affects around 3 to 5% of pregnant women. It has different causes, and in about 50%, it is of unknown etiology. Thrombophilia might increase the risk of RPL by adversely affecting the normal placental vascular function. Our study aimed to determine the frequency of factor V Leiden (FVL) and prothrombin G20210A gene mutations in Algerian women with RPL and to correlate their presence with the occurrence of such health's problem. A total of 80 women with previous fetal losses and 100 age-matched women with no history of fetal loss were recorded. Participants were tested for activated protein C resistance (APCR), protein C (PC), protein S (PS), and antithrombin (AT) deficiencies. The screening of FVL and prothrombin G20210A mutations was also done using a duplex polymerase chain reaction. Results: APCR was detected in 6.25% of cases and was absent in controls (p = 0.011). PC and PS deficiencies were documented in 7.5% of patients. FVL was detected in 8.33% of patients and was absent in controls (p = 0.047). Prothrombin G20210A mutation was found in 8.33% of patients compared to 11.11% of controls (p = 0.631). A significant association of FVL mutation with the abortion which occurred in the second trimester was found (p = 0.001). Conclusion: There is a significant association between FVL mutation and RPL especially the loss occurring during the second trimester. No correlation was found regarding prothrombin G20210A mutation.
