Socio-demographic trends in overweight and obesity among parous and nulliparous women in Ghana

Background Overweight and obesity are among the leading threats to global health because of their association with increased risk of morbidity and mortality. Much of the research on overweight and obesity among women largely generalize without due cognisance to differences in their reproductive history. This study explored differences in trends in overweight/obesity, and associated factors between parous and nulliparous women in Ghana. Methods Anthropometric measurements from three nationally representative Ghana Demographic and Health Surveys (2003, 2008 and 2014) were analysed using descriptive statistics and multivariate binary logistic regression. Results Over all, overweight/obesity increased between 2003 and 2014, with disproportionately higher rates among parous women (from about 30 % in 2003 to about 48 % in 2014) than nulliparous women (from about 15 % in 2003 to about 24 % in 2014). Age, wealth quintile and marital status were associated with overweight/obesity similarly in both women groups. However, there were variations in the association between parous and nulliparious women by educational level, type of locality, occupation and ethnicity. Conclusion The trend of overweight/obesity in Ghana warrants urgent national level public health attention to help curb the situation. Such interventions should be tailored bearing in mind the peculiar differences in associated factors between parous and nulliparous women.BioMed Central open acces

Toxicity, Deficiency and Dysmetabolism of Trace Elements in Ghanaian Clinically Stable Schizophrenics

AIM: The purpose of the study was to determine the levels of Copper (Cu), selenium (Se), Zinc (Zn), Lead (Pb) and Lithium (Li) in patients in Accra and Pantang Psychiatric Hospitals in Ghana since no data exist.SUBJECTS AND METHODS: Simple random sampling of age-matched subjects was used to recruit 81 schizophrenics and 25 mentally healthy controls in 2012. Serum levels of Cu, Se, Zn, Pb and Li were determined by flame atomic absorption spectroscopy (FAAS). RESULTS: Mean levels were as follows: Cut 766 ± 250 µg/L and Cuc 855 ± 270 µg/L (p = 0.168). Set 149 ± 72 µg/L and Sec 108 ± 61 µg/L (p=0.009). Znt 702 ± 438 µg/L and Znc 1007 ± 593 µg/L (p = 0.028). Pbt 1.38 ± 0.05 µg/L and Pbc 0.10 ± 0.05 µg/L (p = 0.000). Li levels for the test group (Lit) was 4077 ± 2567 µg/L, whiles that of the controls was undetectable < 0.02 µg/L. Se, Pb and Li levels were significantly higher in schizophrenic patients compared to controls. While Zn and Cu levels were lower in the same group.CONCLUSION: Trace elements dysmetabolism exist among Ghanaian schizophrenics and monitoring is essential to avoid the adverse effects of metal overload or deficiency

Association of CYP3A5*3 polymorphisms and prostate cancer risk: A meta-analysis

Aim of Study: The CYP3A5*3 allele (A6986G transition in intron 3) is the major member of cytochrome P450 subfamily, which plays a pivotal role in exogenous carcinogens of liver. Variation of the CYP3A5*3 (rs776746 A > G) can lead to oxidation and inactivation of testosterone, which may result in individual susceptibility to prostate cancer. Methods: All eligible published studies about association between CYP3A5*3 polymorphisms and prostate cancer risk were searched in PubMed, Embase, Web of Science, and Cochrane Library, for the period up to August 2015. Odds ratios (ORs) together with 95% confidence intervals (95% CIs) were used to access the strength of the association. Results: Six case–control studies including 2522 cancer patients and 2444 healthy controls were finally included. The meta-analysis results suggested that CYP3A5*3 polymorphisms were significantly associated with an increased risk of prostate cancer under two genetic models (GG + AG vs. AA: OR = 1.53, 95% CI = 1.23–1.90, P = 0.000; GG vs. AA: OR = 1.46, 95% CI = 1.14–1.87, P = 0.000). Further subgroup analysis according to ethnicity indicated that CYP3A5*3 polymorphism may increase the risks of prostate cancer among African (G allele vs. A allele: OR = 1.34, 95% CI = 1.14–1.57, P = 0.000; GG + AG vs. AA: OR = 1.606, 95% CI = 1.27–2.04, P = 0.000). Sensitivity analysis indicated a reliable result and publication bias suggested no strong publication bias under the genetic models. Conclusion: Our data support that the CYP3A5*3 polymorphism may be associated with increased risk of prostate cancer, particularly in African populations. Large and well-designed studies are needed to validate this association

Culture and pandemic control at cross-roads: navigating the burial guidelines for COVID-19-related deaths in a Ghanaian setting

Abstract Background Despite the large volume of scientific evidence on the rapid spread of the COVID-19 pandemic and associated high morbidity and mortality, little is known about the sociocultural disruptions which ensued. The current study explored the nuanced navigation of the COVID-19-related death and burial protocols and its impact on traditional burial and funeral rites in Ghana. Methods This qualitative study was based on the ‘focused’ ethnographic design. Data were collected using key informant interviews from nineteen COVID-19-related bereaved family members and public health officials involved in enforcing adherence to COVID-19-related death and burial protocols in the Cape Coast Metropolis of Central region of Ghana. Recursive analysis was conducted to generate the themes and sub-themes from the data. Results The overarching theme was “Uncultural” connotations ascribed to the COVID-19-related death and burial protocols. The COVID-19-related death and burial protocols were ubiquitously deemed by participants to be ‘uncultural’ as they inhibited deep-rooted indigenous and eschatological rites of separation between the living and the dead. This was fueled by limited awareness and knowledge about the COVID-19 burial protocols, resulting in fierce resistance by bereaved family members who demanded that public health officials release the bodies of their deceased relatives. Such resistance in the midst of resource limitation led to negotiated compromises of the COVID-19-related death and burial protocols between family members and public health officials. Conclusions Insensitivity to socio-cultural practices compromised the implementation of the COVID-19 pandemic control interventions, particularly, the COVID-19-related death and burial protocols. Some compromises that were not sanctioned by the protocols were reached to allow health officials and families respectfully bury their dead. These findings call for the need to prioritize the incorporation of sociocultural practices in future pandemic prevention and management strategies

Cardioprotection mediated by exosomes is impaired in the setting of type II diabetes but can be rescued by the use of non-diabetic exosomes in vitro

Many patients with ischaemic heart disease also have diabetes. As myocardial infarction is a major cause of mortality and morbidity in these patients, treatments that increase cell survival in response to ischaemia and reperfusion are needed. Exosomes—nano-sized, lipid vesicles released from cells—can protect the hearts of non-diabetic rats. We previously showed that exosomal HSP70 activates a cardioprotective signalling pathway in cardiomyocytes culminating in ERK1/2 and HSP27 phosphorylation. Here, we investigated whether the exosomal cardioprotective pathway remains intact in the setting of type II diabetes. Exosomes were isolated by differential centrifugation from non-diabetic and type II diabetic patients, from non-diabetic and Goto Kakizaki type II diabetic rats, and from normoglycaemic and hyperglycaemic endothelial cells. Exosome size and number were not significantly altered by diabetes. CD81 and HSP70 exosome markers were increased in diabetic rat exosomes. However, exosomes from diabetic rats no longer activated the ERK1/2 and HSP27 cardioprotective pathway and were no longer protective in a primary rat cardiomyocytes model of hypoxia and reoxygenation injury. Hyperglycaemic culture conditions were sufficient to impair protection by endothelial exosomes. Importantly, however, exosomes from non-diabetic rats retained the ability to protect cardiomyocytes from diabetic rats. Exosomes from diabetic plasma have lost the ability to protect cardiomyocytes, but protection can be restored with exosomes from non-diabetic plasma. These results support the concept that exosomes may be used to protect cardiomyocytes against ischaemia and reperfusion injury, even in the setting of type II diabetes

Endogenous Sphingolipid Signaling Pathway Implicated in the Action of Croton membranaceus on the Prostate Gland in BPH Patients

Background: Croton membranaceus extract has apoptotic effects on BPH-1 cells. This study determined if the apoptotic effects were created through the ceramide pathway. Methods: The study was a follow-up to a previous observational study of 30 histologically confirmed patients with benign prostatic hyperplasia (BPH) who were on C. membranaceus ethanolic extract at 20 mg t.i.d orally for 3 mo. Thereafter, total and free prostate-specific antigen (PSA), lipid profile plus Apo lipoprotein A and B, ceramide/Sphingophospho-kinase 1 (SphK1) and 2 (SphK2), sphingosine lyase (SPL), the cytotoxic adducts of oxidative stress 4-hydroxy-2-nonenal (4HNE) and malondialdehyde (MDA), were determined. Results: Total and free PSA were significantly (p < 0.05) different after treatment. Apo lipoprotein A was significantly different (p = 0.024). The SphK1/SphK2 ratio reduced significantly (p = 0.049). Furthermore, SPL, ceramide, and MDA increased significantly after treatment (p = 0.05, p = 0.004, and p = 0.007, respectively). A weak positive correlation was found between high-density lipoprotein (HDL) cholesterol and SphK1, and HDL and ceramide before treatment (p = 0.036, r = 0.3826; p = 0.018, r = 0.4286, respectively. Conclusions: C. membranaceus uses the ceramide pathway by modulating the SphK1/SphK2 ratio and increasing SPL to generate oxidative stress and consequently apoptosis
