Bumblebee Abundance in Species-Rich Grasslands in Southern Sweden Decreases with Increasing Amount of Arable Land at a Landscape Level.

Conservation of bumblebee populations is essential because of their role as pollinators. Declines in bumblebee abundance have been documented in recent decades, mostly attributed to agricultural intensification, landscape simplification and loss of semi-natural grasslands. In this study, we investigated the effects of landscape composition on bumblebee abundance at different spatial scales in 476 semi-natural grassland sites in southern Sweden.

Assessment of Right Ventricular Systolic Function using Tricuspid Annular Plane Systolic Excursion (TAPSE) among HIV Patients on HAART and Its Relationship with Viral Load and CD4 Cell Count.

Background: The introduction of highly active antiretroviral therapy (HAART) has decreased the morbidity and mortality associated with HIV infection; however, this survival advantage is not free from complications. HIV patients are more likely to develop cardiovascular disease compared with the general population, and right ventricular systolic dysfunction is said to be associated with worse outcomes. We, therefore, sought to assess right ventricular systolic function using tricuspid annular plain systolic excursion (TAPSE) among HIV patients on HAART and its relationship with viral load and CD4 cell count.

Prevalence of Doppler-Derived Left Ventricular Diastolic Dysfunction Among Newly Diagnosed Hypertensive Patients.

Background: The initial sign of hypertensive heart disease (HHD) is left ventricular diastolic dysfunction (LVDD), which is caused by remodeling of the left ventricle and left atrium, resulting in impaired relaxation of the left ventricle. LVDD is also partly due to left ventricular hypertrophy (LVH). If left untreated, LVDD can progress to diastolic heart failure and systolic heart failure.

Clinical Profile of Patients with Hypertensive Emergency Referred to a Tertiary Hospital in the Western Cape Province of South Africa.

Background: Despite advances in managing hypertension, hypertensive emergencies remain a common indication for emergency room visits. Our study aimed to determine the clinical profile of patients referred with hypertensive emergencies.

Methods: We conducted an observational study involving patients aged ≥18 years referred with hypertensive crisis.

Myocardial Tissue Characterization in Patients with Hypertensive Crisis, Positive Troponin, and Unobstructed Coronary Arteries: A Cardiovascular Magnetic Resonance-Based Study.

Hypertensive crisis can present with cardiac troponin elevation and unobstructed coronary arteries. We used cardiac magnetic resonance (CMR) imaging to characterize the myocardial tissue in patients with hypertensive crisis, elevated cardiac troponin, and unobstructed coronary arteries. Patients with hypertensive crisis and elevated cardiac troponin with coronary artery stenosis <50% were enrolled.

The Role of Cardiac Biomarkers in the Diagnosis of Hypertensive Emergency.

There is a growing interest in the role of biomarkers in differentiating hypertensive emergency from hypertensive urgency. This study aimed to determine the diagnostic utility of lactate dehydrogenase (LDH), high-sensitivity cardiac troponin T (hscTnT), and N-terminal prohormone of brain-type natriuretic peptide (NT-proBNP) for identifying hypertensive emergency. A diagnosis of hypertensive emergency was made based on a systolic blood pressure of ≥180 mmHg and/or a diastolic blood pressure of ≥110 mmHg with acute hypertension-mediated organ damage.

Echocardiographic Left Ventricular Hypertrophy and Geometric Patterns in Patients with Sickle Cell Anaemia.

Background: Left ventricular hypertrophy (LVH) is a common complication in patients with sickle cell anaemia (SCA), and it has been associated with systolic and diastolic dysfunction, and sudden death. There is a wide variation in the reported prevalence of LVH in patients with SCA, partly due to the varying criteria applied, and the impact of small weight and body surface area (BSA) in SCA patients. We used four different criteria to determine echocardiographic LVH and geometric patterns in patients with steady-state SCA.

Altered cardiac structure and function in newly diagnosed people living with HIV: a prospective cardiovascular magnetic resonance study after the initiation of antiretroviral treatment.

HIV associated cardiomyopathy (HIVAC) is a poorly understood entity that may progress along a continuum. We evaluated a group of persons newly diagnosed with HIV and studied the evolution of cardiac abnormalities after ART initiation. We recruited a group of newly diagnosed, ART naïve persons with HIV and a healthy, HIV uninfected group.

Land sharing complements land sparing in the conservation of disturbance-dependent species.

Alteration of natural disturbances in human-modified landscapes has resulted in many disturbance-dependent species becoming rare. Conservation of such species requires efforts to maintain or recreate disturbance regimes. We compared benefits of confining efforts to habitats in protected areas (a form of land sparing) versus integrating them with general management of production land (a form of land sharing), using two examples: fire in forests and grazing in semi-natural grasslands.

Influence of systolic blood pressure on outcomes in Nigerians with peripartum cardiomyopathy.

Background: The relationship between blood pressure (BP) trajectories and outcomes in patients with peripartum cardiomyopathy (PPCM) is not clear. Aim: The study aimed to assess the clinical features and outcomes (all-cause mortality and unrecovered left ventricular [LV] systolic function) of PPCM patients grouped according to their baseline systolic BP (SBP).

Patients And Methods: PPCM patients presenting to 14 tertiary hospitals in Nigeria were consecutively recruited between June 2017 and March 2018 and then followed up till March 2019.

Evolution of myocardial oedema and fibrosis in HIV infected persons after the initiation of antiretroviral therapy: a prospective cardiovascular magnetic resonance study.

Background: Human immunodeficiency virus (HIV) infected persons on antiretroviral therapy (ART) have been shown to have functionally and structurally altered ventricles and may be related to cardiovascular inflammation. Mounting evidence suggests that the myocardium of HIV infected individuals may be abnormal before ART is initiated and may represent subclinical HIV-associated cardiomyopathy (HIVAC). The influence of ART on subclinical HIVAC is not known.

Impact of Climate Change on Management of Systemic Hypertension in North-Eastern Nigeria.

The impact of climate change on health, including changes in epidemiology and heat-related complications, has been variously reported in many parts of the world. Maiduguri, the capital of Borno state in north-eastern Nigeria, has been bearing the brunt of increasing temperatures over the past years, especially during the early months of the year building up to the commencement of the rainy season; with an average daily temperature forecasted to be around 40C. Patients with systemic hypertension and other forms of cardiovascular diseases are vulnerable to heat-related complications including dehydration, hypotension, and orthostatic hypotension (OH).

Digoxin and Symptomatic Bradyarrhythmia: the 'demon' or a 'red herring'.

Digoxin toxicity has been implicated in all forms of cardiac arrhythmias with the notable exception of Mobitz II atrioventricular block, which is very rare. The manifestation is quite variable, ranging from being asymptomatic to gastrointestinal, cardiac, and neurologic symptoms. The manifestations can be protean in the elderly, the most vulnerable group, where degenerative cardiac conduction system diseases add another layer of intrigue by providing an intrinsic substrate for cardiac dysrhythmia.

Cardiac Complications of Hypertensive Emergency: Classification, Diagnosis and Management Challenges.

While mortality in patients with hypertensive emergency has significantly improved over the past decades, the incidence and complications associated with acute hypertension-mediated organ damage have not followed a similar trend. Hypertensive emergency is characterized by an abrupt surge in blood pressure, mostly occurring in people with pre-existing hypertension to result in acute hypertension-mediated organ damage. Acute hypertension-mediated organ damage commonly affects the cardiovascular system, and present as acute heart failure, myocardial infarction, and less commonly, acute aortic syndrome.

Objectifying High-Definition Brazilian Buttock Lift Results Using the Buttock Assessment Tool.

Background: The buttock is an essential feature of the female silhouette. This has led to the rise of the Brazilian butt lift as one of the most popular plastic surgery procedures in recent years. Despite this popularity, there remains no prevailing standard for the ideal buttock size and shape.

Relationship between CD4 Cell Count, Viral Load and Left Ventricular Function among HIV-1 Infected Patients Asymptomatic for Cardiac Disease on HAART.

Introduction: Human immunodeficiency virus (HIV) infected patients are at increased risk for myocardial infarction and cardiomyopathy. Low CD4 cell count and high viral load were identified as independent risk factors for cardiac disease. Asymptomatic cardiac dysfunction has also been reported in HIV-infected individuals.

Clinical Features and Outcomes of Peripartum Cardiomyopathy in Nigeria.

Objectives: The purpose of this study was to examine the clinical profile, myocardial remodeling, and survival of patients with PPCM in Nigeria.

Cardiac Pacing Training in Africa: Endorsed by the Africa Heart Rhythm Association (AFHRA): JACC International.

The field of pacing in Africa has evolved in an uncoordinated way across the continent with significant variation in local expertise, cost, and utilization. There are many countries where pacemaker services do not meet one-hundredth of the national demand. Regional, national, and institutional standards for pacemaker qualification and credentials are lacking.

Incidence, clinical characteristics, and risk factors of peripartum cardiomyopathy in Nigeria: results from the PEACE Registry.

Aims: The aim of this study was to describe the incidence, clinical characteristics and risk factors of peripartum cardiomyopathy (PPCM) in Nigeria.

Methods And Results: The study was conducted in 22 hospitals in Nigeria, and PPCM patients were consecutively recruited between June 2017 and March 2018. To determine factors associated with PPCM, the patients were compared with apparently healthy women who recently delivered, as controls.

Hypertrophic Cardiomyopathy and Wolff-Parkinson-White Syndrome in a Young African Soldier with Recurrent Syncope.

Syncope is a common manifestation of both hypertrophic cardiomyopathy (HCM) and Wolff-Parkinson-White (WPW) syndrome. The most common arrhythmia in HCM is ventricular tachycardia (VT) and atrial fibrillation (AF). While preexcitation provides the substrate for reentry and supraventricular tachycardia (SVT), AF is more common in patients with preexcitation than the general population.
