Abstract Aims The aim of this study was to describe the incidence, clinical characteristics and risk factors peripartum cardiomyopathy (PPCM) in Nigeria. Methods Results conducted 22 hospitals Nigeria, PPCM patients were consecutively recruited between June 2017 March 2018. To determine associated with PPCM, compared apparently healthy women who recently delivered, as controls. Four hundred six 99 incidence disease burden (based on rate consecutive recruitment subjects) varied widely...

Background: Peripartum cardiomyopathy (PPCM) is a life-threatening heart muscle disease of unknown aetiology that affects women during the peripartum period, particularly in sub-Saharan Africa. While many studies have observed normal blood pressure (BP) PPCM patients, none explored whether their BP appropriate for body size. This study investigated correlation between anthropometric parameters and comparing findings with those age-matched controls. Methods: A cohort 105 women, each from...

This study explored the hematological and histopathological effects of tramadol administration in Wistar albino rats. A total 28 adult rats were allocated into four groups based on sex treatment status. Tramadol was administered at a dosage 100 mg/kg daily for weeks to simulate chronic misuse, while control received normal saline. Hematological parameters, such as PCV, RBC, hemoglobin concentration, MCV, MCH, MCHC, WBC, differential leukocyte counts, assessed using an automated hematology...

Vehicles that use natural gas exhibit lower costs and emissions, when compared to the gasoline-fuelled vehicle. The present challenge of is how improve its energy density. This research solves problem density by studying storage technologies with improved adsorbent. Comparisons between two systems, thus; adsorbent conventional method are made technically based on associated amount moles. We also compare in different cylinder types (Kusmiyati et al., 2004, Wei 2015 Torregrosa 2013) weight...

Background Coronary artery disease was hitherto a rarity in Africa. Acute coronary syndrome (ACS) accounts for disease-related morbidity and mortality. Reports on ACS Africa are few. Methods Results We enrolled 1072 indigenous Nigerian people 59.2±12.4 years old (men, 66.8%) with an observational multicentered national registry (2013-2018). Outcome measures included incidence, intervention times, reperfusion rates, 1-year The incidence of 59.1 per 100 000 hospitalized adults year, comprised...

Venous thromboembolism is a common medical condition encountered in emergency departments and major contributor to global disease burden. It's often misdiagnosed critically ill patients despite being because of its non-specific features, diagnosis times at autopsy. Hence, it's masquerader that can mimic other cardiorespiratory diseases.
