Malaria Burden and Trend Among Clients Seeking Healthcare in the Western Region: A 4-Year Retrospective Study at the Sefwi-Wiawso Municipal Hospital, Ghana

Background:

Malaria cases continue to rise despite sustained efforts directed at eliminating the burden among Ghanaians. This study was aimed at describing the spectrum of malaria burden in a four-year (2013-2016) retrospective review among clients seeking care at the Sefwi-Wiawso Municipal Hospital in the Western Region of Ghana.

Materials and Methods:

The study analyzed secondary data extracted on 32,629 patients who were referred to the Laboratory for malaria testing from January 2013 to December 2016. Socio-demographic data included age and gender, department of test requisition and malaria results were obtained from the archived Daily Malaria Logbook records. Approval for the study was granted by the authorities of the Sefwi-Wiawso Municipal Hospital.

Results:

The overall confirmed malaria case was 8629 (26.5%), among under five 1,384 (58.7%), pregnant women 4451 (20.3%) and 14.1% among asymptomatic population. Significant gender disparity in the confirmation of suspected malaria cases was observed with males recording higher rate (45.8%) than females (36.7%). The peak of the malaria epidemic was observed in the wet season (195 cases per month), compared to the dry season (133 cases per month).

Conclusion:

Cases of malaria is increasing with high rates among vulnerable groups in the Western Region. There is the need to intensify efforts to reduce the burden in the study area especially among vulnerable groups.

Cardiometabolic Risk Factors among Healthcare Workers: A Cross-Sectional Study at the Sefwi-Wiawso Municipal Hospital, Ghana

BACKGROUND

There is a dearth of information about the burden of cardiometabolic risk factors among the Ghanaian health workforce in the Western Region. This study sought to determine the prevalence of cardiometabolic risk factors among healthcare workers at the Sefwi-Wiawso Municipal Hospital in the Western Region of Ghana.

MATERIALS AND METHODS

A hospital-based cross-sectional study involving 112 employees of the Sefwi-Wiawso Municipal Hospital was conducted. The cardiometabolic risk variables assessed were obesity, hypertension, dyslipidaemia, and diabetes. Sociodemographic parameters were also captured. The prevalence of hypertension and obesity was determined using the JNC VII panel and WHO BMI criteria for obesity classifications. Blood lipids and glucose concentrations were evaluated using standard methods.

RESULTS

The prevalence of hypertension and prehypertension was 16.07% and 52.68%, respectively. About 38.39% of participants were overweight, and 12.50% were obese. Atherogenic dyslipidaemia was 26.79%, whereas prediabetes glycaemic levels and diabetes incidence were 5.41% and 4.50%, respectively. Fifty percent (50.00%) of participants presented at least one cardiometabolic risk factor. Aging and adiposity were associated with increasing cardiometabolic risk.

CONCLUSION

Cardiometabolic risk factors are prevalent among healthcare providers in Sefwi-Wiawso. The cardiometabolic dysregulation observed among this cohort of healthcare professionals may be modulated by age and adiposity.

Aspects of the geochemistry of arsenic and antimony, exemplified by the Skaergaard intrusion

The distribution of As and Sb in a series of Skaergaard rocks and some of their minerals has been investigated using neutron activation analysis, and the geochemical behaviour of these elements during the fractionation of a basic magma is discussed.

It is concluded that As3+ is probably accepted into octahedral lattice sites usually occupied by Fe3+, Mg2+, Ti4+, and Al3+, and that there is also some substitution of As5+ for Si4+ and Al3+ in tetrahedral sites. There is a strong tendency for the element to concentrate in both interstitial and late-stage liquids.

Sb seems to show a marked preferential entry into early (magnesian) olivines, as in the case of Ni. The analytical results indicate that the substitution of Sb3+ for Fe2+ probably accounts for most of the Sb in silicate and oxide minerals. The tendency for Sb to concentrate in the residual Skaergaard liquids is less marked than in the case of As, but greater than in the cases of V, Cr, and Ni.

As and Sb have also been determined in four chondritic meteorites, in which the As/Sb ratio ranges from 8·5–12·4. Analyses for As and Sb in the standard rock powders G-1 and W-1 have also been made.

Insights into nasal carriage of Staphylococcus aureus in an urban and a rural community in Ghana

The epidemiology of Staphylococcus aureus in the community in Ghana was never investigated prior to this study. The aims of the study were: i) to assess prevalence of nasal S. aureus carriage in Ghanaian people living in an urban and a rural area, and ii) to identify phenotypic and genotypic traits of strains isolated from the two communities. Nasal swabs were collected from healthy individuals living in an urban community situated in the suburb of the capital city, Accra (n = 353) and in a rural community situated in the Dangme-West district (n = 234). The overall prevalence of nasal carriage was 21% with a significantly higher prevalence in the urban (28%) than in the rural community (11%) (p<0.0001). The levels of antimicrobial resistance were generally low (<5%) except for penicillin (91%) and tetracycline (25%). The only two (0.3%) MRSA carriers were individuals living in the urban area and had been exposed to hospitals within the last 12 months prior to sampling. Resistance to tetracycline (p = 0.0009) and presence of Panton-Valentine leukocidin (PVL) gene (p = 0.02) were significantly higher among isolates from the rural community compared to isolates from the urban community. Eleven MLST clonal complexes (CC) were detected based on spa typing of the 124 S. aureus isolates from the two communities: CC8 (n = 36), CC152 (n = 21), CC45 (n = 21), CC15 (n = 18), CC121 (n = 6), CC97 (n = 6), CC30 (n = 5), CC5 (n = 5), CC508 (n = 4), CC9 (n = 1), and CC707 (n = 1). CC8 and CC45 were less frequent in the rural area than in the urban area (p = 0.02). These results reveal remarkable differences regarding carriage prevalence, tetracycline resistance, PVL content and clonal distribution of S. aureus in the two study populations. Future research may be required to establish whether such differences in nasal S. aureus carriage are linked to socio-economic differences between urban and rural communities in this African country.

Mineralogical and petrological investigations of lunar samples

Fragments of igneous rocks and breccias, and one coarse-grained rock with thin sections, have been studied. Minerals found include pyroxene, plagioclase, olivine, ilmenite, troilite, ulvöspinel, native iron, cristobalite, tridymite, alkali feldspar, apatite, and quartz. Textures are described and interpreted. Among features revealed by optical, microprobe, x-ray diffraction, and electron microscope methods are extreme zoning and unmixing in pyroxene grains, compositional variations in ilmenites, and effects of shock metamorphism. Some trace elements were determined by x-ray fluorescence analysis.
