Pulmonary hypertension (PH) is rarely a cause of syncope. We highlight an unusual presentation of pulmonary hypertension where management was a veritable challenge. We present a case report of a 35-year-old female with a history of stage 2 hypertension, polycystic ovarian syndrome, and obesity who presented to the hospital with a six-month history of progressive shortness of breath, lower extremity swelling, and recurrent syncope.

Methods: We searched PubMed, EMBASE, Web of Science and CINHAL from inception up to November 2019 for studies on cholangiocarcinoma in Africa.
Background: We examined differences in mortality among coronavirus disease 2019 (COVID-19) cases in the first, second, and third waves of the COVID-19 pandemic.
Methods: A retrospective cohort study of COVID-19 cases in Fulton County, Georgia, USA, reported to a public health surveillance from March 2020 through February 2021. We estimated case-fatality rates (CFR) by wave and used Cox proportional hazards random-effects models in each wave, with random effects at individual and long-term-care-facility level, to determine risk factors associated with rates of mortality.
Perioperative acute cardiac tamponade associated with perforation from pulmonary vein isolation (PVI) and radiofrequency catheter ablation (RFCA) for the treatment of refractory atrial fibrillation (AF) is rare. If not identified early and managed promptly, it can lead to decreased ejection fraction, hypotension, and ultimately death. We report a case of acute tamponade that was diagnosed and successfully managed following PVI and RFCA.

Methods: a retrospective analysis of data from Cancer Diseases Hospital (CDH) database was conducted on EC patients diagnosed between 2007 and December 2018. Medical records of EC patients were manually retrieved and reviewed using medical record numbers identified from the CDH database.
Background: We present data on risk factors for severe outcomes among patients with coronavirus disease 2019 (COVID-19) in the southeast United States (U.S.).
View Article and Find Full Text PDFBackground: Esophageal cancer (EC) is associated with a poor prognosis, particularly so in Africa where an alarmingly high mortality to incidence ratio prevails for this disease.
Aim: To provide further understanding of EC in the context of the unique cultural and genetic diversity, and socio-economic challenges faced on the African continent.
Methods: We performed a systematic review of studies from Africa to obtain data on epidemiology, risk factors, management and outcomes of EC.
Background: Plasma volume (PV) is contracted in stable patients with heart failure (HF) due to decongestion strategies. On the other hand, increased PV can adversely affect the trajectory of HF. We therefore examined the effects of increased percentage change in PV (%ΔPV), blood urea nitrogen (BUN), and %ΔPV stratified by BUN and glomerular filtration rate (GFR) on survival after discharge in patients hospitalized for acute decompensated HF (ADHF).

This study sought to determine the associations between male involvement in antenatal care (ANC) services and pregnant women delivering at health facilities and being attended to by skilled birth attendants as well as attending postnatal care. This was a retrospective cohort study using secondary analysis of program data.

To improve the quality of HIV/AIDS services, ZPCT II provides technical assistance until desired standards are met and districts are weaned-off intensive technical support, a process referred to as district graduation. This study describes the graduation process and determines performance domains associated with district graduation.

Home based interventions have been identified as possible strategies for decentralizing ART care and improving access and adherence to ART. There is need for evidence at individual- or community-level of the benefits of home-based interventions in improving HIV suppression in African patients receiving ART.

Methods: 649 adult patients receiving treatment for HIV and/or TB at PHCs in Zambia (363 males, 286 females) were recruited between 1st December 2009 and 31st January 2010. Data on socio-demographic variables, clinical disease features (TB and HIV), and psychopathological status were collected.
Background: Southern Africa has had an unprecedented increase in the burden of tuberculosis, driven by the HIV epidemic. The Zambia, South Africa Tuberculosis and AIDS Reduction (ZAMSTAR) trial examined two public health interventions that aimed to reduce the burden of tuberculosis by facilitating either rapid sputum diagnosis or integrating tuberculosis and HIV services within the community.
Methods: ZAMSTAR was a community-randomised trial done in Zambia and the Western Cape province of South Africa.
We determined the frequency and correlates of current common mental disorders (CMDs) in a consecutive series of 649 adult patients with human immunodeficiency virus (HIV), tuberculosis (TB) or both receiving treatment at 16 primary health care centres across Zambia. Data on socio-demographic variables, clinical disease features, anxiety and mood disorders were collected. The frequency of any anxiety disorder (AD) was 30.
View Article and Find Full Text PDFObjectives: To conduct a systematic review of the literature to examine the interrelationship between mental health and treatment outcomes in low-income and middle-income settings; to update the work of Collins et al. (2006).
Design: Systematic review of peer-reviewed articles that examined one of the following: the effects of mental disorders (including cognitive impairment) upon engagement with treatment and/or adherence; their influence upon HIV-related clinical outcomes; and the impact of interventions for mental disorder.
Background: Several frameworks have been constructed to analyse the factors which influence and shape the uptake of evidence into policy processes in resource poor settings, yet empirical analyses of health policy making in these settings are relatively rare. National policy making for cotrimoxazole (trimethoprim-sulfamethoxazole) preventive therapy in developing countries offers a pertinent case for the application of a policy analysis lens. The provision of cotrimoxazole as a prophylaxis is an inexpensive and highly efficacious preventative intervention in HIV infected individuals, reducing both morbidity and mortality among adults and children with HIV/AIDS, yet evidence suggests that it has not been quickly or evenly scaled-up in resource poor settings.

Methods: This was a cross-sectional study in 16 primary level care clinics. Consecutive sampling was used to select 649 participants who started TB treatment or ART in the preceding month.
In the April 2010 issue of this journal, Date et al. expressed concern over the slow scale-up in low-income settings of two therapies for the prevention of opportunistic infections in people living with the human immunodeficiency virus: co-trimoxazole prophylaxis and isoniazid preventive therapy. This short paper discusses the important ways in which policy analysis can be of use in understanding and explaining how and why certain evidence makes its way into policy and practice and what local factors influence this process.
