Ideal cardiovascular health among Ghanaian populations in three European countries and rural and urban Ghana: the RODAM study

Cardiovascular health (CVH) is a construct defined by the American Heart Association (AHA) as part of its 2020 Impact Goal definition. CVH has, until now, not been evaluated in Sub-Saharan African populations. The aim of this study was to investigate differences in the prevalence of ideal CVH and its constituent metrics among Ghanaians living in rural and urban Ghana and Ghanaian migrants living in three European countries. The AHA definition of CVH is based on 7 metrics: smoking, body mass index, diet, physical activity, blood pressure, total cholesterol, and fasting plasma glucose. These were evaluated among 3510 Ghanaian adults (aged 25–70 years) residing in rural and urban Ghana and three European cities (Amsterdam, London and Berlin) in the multi-centre RODAM study. Differences between groups were assessed using logistic regression with adjustments for gender, age, and education. Only 0.3% of all participants met all 7 metrics of the AHA’s definition of ideal CVH. Compared to rural Ghana (25.7%), the proportions and adjusted odds ratio (OR) of individuals who had 6–7 CVH metrics in the ideal category were substantially lower in urban Ghana, (7.5%; OR 0.204, 95% CI 0.15–0.29), Amsterdam (4.4%; 0.13, 0.08–0.19), Berlin (2.7%; 0.06, 0.03–0.11), and London (1.7%; 0.04, 0.02–0.09), respectively. The proportion of ideal CVH for the various metrics ranged from 96% for all sites in the smoking metric to below 6% in the diet metric. The proportion of ideal CVH is extremely low in Ghanaians, especially among those living in urban Ghana and Ghanaian migrants in Europe.     

Developing effective chronic disease interventions in Africa: insights from Ghana and Cameroon

Background  

Africa faces an urgent but 'neglected epidemic' of chronic disease. In some countries stroke, hypertension, diabetes and cancers cause a greater number of adult medical admissions and deaths compared to communicable diseases such as HIV/AIDS or tuberculosis. Experts propose a three-pronged solution consisting of epidemiological surveillance, primary prevention and secondary prevention. In addition, interventions must be implemented through 'multifaceted multi-institutional' strategies that make efficient use of limited economic and human resources. Epidemiological surveillance has been prioritised over primary and secondary prevention. We discuss the challenge of developing effective primary and secondary prevention to tackle Africa's chronic disease epidemic through in-depth case studies of Ghanaian and Cameroonian responses.

Chronic non-communicable diseases and the challenge of universal health coverage: insights from community-based cardiovascular disease research in urban poor communities in Accra,Ghana

Background

The rising burden of chronic non-communicable diseases in low and middle income countries has major implications on the ability of these countries to achieve universal health coverage. In this paper we discuss the impact of cardiovascular diseases (CVD) on primary healthcare services in urban poor communities in Accra, Ghana.

Methods

We review the evidence on the evolution of universal health coverage in Ghana and the central role of the community-based health planning services (CHPS) programme and the National Health Insurance Scheme in primary health care. We present preliminary findings from a study on community CVD knowledge, experiences, responses and access to services.

Results

The rising burden of NCDs in Ghana will affect the achievement of universal health coverage, particularly in urban areas. There is a significant unmet need for CVD care in the study communities. The provision of primary healthcare services for CVD is not accessible, equitable or responsive to the needs of target communities.

Conclusions

We consider these findings in the context of the primary healthcare system and discuss the challenges and opportunities for strengthening health systems in low and middle-income countries.

     

A feasibility study of simultaneous administration of gemtuzumab ozogamicin with intensive chemotherapy in induction and consolidation in younger patients with acute myeloid leukemia

The feasibility of combining gemtuzumab ozogamicin (GO) with intensive chemotherapy as first-line treatment of acute myeloid leukemia (AML) was assessed in 72 patients, aged 17 to 59 years, as a prelude to the United Kingdom Medical Research Council (MRC) AML15 trial. Sixty-four patients received induction chemotherapy (DAT [daunorubicin, ara-C, thioguanine], DA [daunorubicin, ara-C], or FLAG-Ida [fludarabine, ara-C, G-CSF, idarubicin]) with GO on day 1. It was possible to give GO 3 mg/m2 with course 1, but 6 mg/m2 with course 1 or GO in a dose of 3 mg/m2 with consecutive courses was not feasible because of hepatotoxicity and delayed hematopoietic recovery. Thirty-one patients who were treated in consolidation with MACE (amsacrine, ara-C, etoposide) or HidAC (HidAC) and GO (3 mg/m2), and 23 in induction and consolidation, tolerated GO (3 mg/m2) well. Grade 4 liver toxicity and sinusoidal obstructive syndrome was more common in thioguanine-containing schedules (P =.007). Remission with course 1 was seen in 86% of patients. DA or FLAG-Ida with GO in induction achieved complete remission in 91% of patients and 78% of these patients are in continuous complete remission at 8 months. GO given with induction (DA or FLAG-Ida) and consolidation (MACE or HidAC) was well tolerated. These schedules are now being compared in the MRC AML15 trial in patients younger than 60 years.     

The prevalence and associated mortality of non-anaemic iron deficiency in older adults: a 14 years observational cohort study

Iron is central to multiple biological pathways, and treatment of non-anaemic absolute iron deficiency (NAID) is beneficial in certain conditions. However, it is unknown if NAID is associated with increased mortality in older adults. A nationally representative sample of 4451 older adults from the English Longitudinal Study of Ageing was used. NAID was defined as serum ferritin < 30 μg/l and haemoglobin ≥ 120 g/l (women) or ≥ 130 g/l (men). Cumulative mortality was estimated by Kaplan–Meier method. Unadjusted and adjusted hazard ratios (HRs) of mortality were calculated using Cox proportional hazards regression models. Baseline NAID prevalence was 8·8% (95% confidence interval [CI] 8·0–9·7%); 10·9% (95% CI 9·7–12·3%) for women and 6·35% for men (95% CI 5·3–7·5%). The HR for mortality for individuals with NAID compared with non-anaemic individuals without iron deficiency over the 14-year follow-up was 1·58 (95% CI 1·29–1·93). This association was independent of all identified demographic, health-related and biological covariates, and robust in multiple sensitivity analyses. In older adults in England, NAID is common and associated with an increased mortality rate compared to non-anaemic individuals with normal serum ferritin. The association is principally driven by an excess mortality in women.     

The relationship between craniofacial anatomy and obstructive sleep apnoea: a case-controlled study

The aim of the study was to identify craniofacial and pharyngeal anatomical factors directly related to obstructive sleep apnoea (OSA). The design and setting was a hospital-based, case-controlled study. Ninety-nine subjects (78 males and 21 females) with a confirmed diagnosis of OSA, who were referred to the Dental Hospital for construction of a mandibular advancement splint were recruited. A similar number of control subjects, matched for age and sex, were recruited after completing snoring and Epworth Sleepiness Scale questionnaires to exclude habitual snoring and daytime sleepiness. An upright cephalogram was obtained and skeletal and soft tissue landmarks were traced and digitized. In OSA subjects the anteroposterior skeletal measurements, including maxillary and mandibular length were reduced (P < 0.001). The intermaxillary space was found to be 3.1 mm shorter in OSA subjects (P = 0.001). The nasopharyngeal airway in OSA subjects was narrower (P < 0.001) but pharyngeal length showed no difference. The tongue size was increased (P = 0.021), soft plate length, thickness and area were all greater (P < 0.001) and the hyoid bone was more inferiorly positioned in OSA subjects (P < 0.001). This study identifies a significant number of craniofacial and pharyngeal anatomical factors directly related to OSA.
