Kaiso Expression in Triple Negative Breast Cancer in a Tertiary Hospital in Ghana.

Background: Breast cancer has produced more lost disability-adjusted life years (DALYs) than any other type of cancer. The prevalence of the disease, especially triple negative breast cancer (TNBC) in Africa is on the rise, with poor survival rates. With the great advancements in treatments of breast cancers, that of TNBC is still a challenge due to its narrowed treatment options and poor disease prognosis. This research seeks to explore the expression of kaiso in Ghanaian breast cancer and how they may modulate clinicopathological features, and disease prognosis. Methodology: A cross-sectional retrospective study was conducted on formalin-fixed paraffin-embedded (FFPE) breast cancer tissues retrieved from the archives of the pathology unit of Komfo Anokye Teaching Hospital (KATH). Immunohistochemistry assessment was performed on haematoxylin and eosin-stained slides selected for tissue microarray construction. Data were analysed using SPSS version 28 and Microsoft excel 2013. Results: 55.3% of the cases tested negative to progesterone receptor (PR), oestrogen receptor (ER), and human epidermal growth receptor 2 (HER2). There were significant associations between menopausal status and molecular subtype (p=0.010), Kaiso expression and histological diagnoses (<0.001) and Kaiso against lymphovascular invasion (0.050). However, there were no significant associations between Kaiso localization and the clinicopathological features although 63.9% of the expression was seen in the nucleus. Conclusion: The study indicates that Kaiso is highly expressed in Ghanaian TNBC and likely associated with worse outcomes in aggressive tumour types.

Assessment of Reproductive Toxicity of Hydroethanolic Root Extracts of Caesalpinia benthamiana, Sphenocentrum jollyanum, and Paullinia pinnata.

PURPOSE: Male sexual dysfunction negatively affects an individual's quality of life and thus its of prime public concern, hence the need to boost reproductive abilities in such individuals. This study assessed the effect of hydroethanolic root extracts of Caesalpinia benthamiana (CBRE), Sphenocentrum jollyanum (SJRE), and Paullinia pinnata (PPRE), commonly used as aphrodisiacs in Ghana, using male Sprague-Dawley rats. METHODS: Plasma testosterone, follicle-stimulating hormone, and luteinizing hormone were assayed in grouped rats treated orally with 1 mL/kg normal saline, 50 mg/kg monosodium glutamate (MSG), and 100, 300, or 1000 mg/kg CBRE, SJRE, and PPRE, respectively, for 60 days. Epididymis and testis weights were determined. Semen was assessed on spermatozoa count, motility, and morphology. Malonyladehyde formation in lipid-peroxidation assay and histological examinations were performed to assess pathological changes in testes. Testicular testosterone was also assayed. RESULTS: While MSG, CBRE, SJRE, and PPRE treatments did not result in significant reduction (p>0.05) in plasma testosterone, there was significant reduction (p≤0.05 -0.0001) in plasma luteinizing hormone, and follicle-stimulating hormone. The combined mean wet weights of epididymides and testes of all treated groups did not vary significantly (p>0.05) from the control. There was significant reduction (p≤0.0001) in sperm motility and count, with significant morphological changes (p≤0.05-0.001), ie, bent necks, tails, and midpieces, and multiple anomalies in the spermatozoa in extract and MSG-treated groups. There was also significant (p≤0.0001) reduction in testicular testosterone among all treatment groups. CONCLUSION: Hydroethanolic CBRE, SJRE, and PPRE were found to have detrimental effects on reproductive function with prolonged usage and thus may not be safe to use in healthy males who intend to reproduce.

Hepatitis B and C infections in HIV-1 and non-HIV infected pregnant women in the Brong-Ahafo Region, Ghana.

BACKGROUND: Hepatitis B (HBV) or hepatitis C (HCV) virus co-infections in HIV are alarming during pregnancy due to the risk of vertical transmission and the eventual adverse effects on neonates. This study was conducted to ascertain the sero-prevalence of HIV/HBV and HIV/HCV co-infections, evaluate the effect of the co-infections on the immunological and virological characteristics and assess the association between some demographic and lifestyle characteristics and risk of HBV, HCV, HIV/HBV and HIV/HCV co-infections among pregnant women living in the Brong-Ahafo Region of Ghana. METHODS: This comparative cross-sectional study was conducted at the anti-retroviral therapy (ART) clinics of the St. Elizabeth Hospital and the Holy Family Hospital, Brong-Ahafo Region, Ghana. A total of 248 consecutive consenting pregnant Ghanaian women, 148 diagnosed with HIV [HIV (+)] and 100 who were HIV negative [HIV (-)], were recruited. Validated questionnaire was used to obtain demographic and lifestyle data. Venous blood samples were obtained and HCV status, HBV profile, CD4+ T cell count, and HIV-1 RNA load were determined. RESULTS: The sero-prevalence of HIV (+) /HBV, HIV (+) /HCV, HIV (-)/HBV, and HIV (-)/HCV infections were 22 (14.9%), 6 (4.1%), 10 (10.0%), and 12 (12.0%) respectively. HIV-1 viral load was not significantly different between HIV/HBV, HIV/HCV co-infection and HIV mono-infection. However, CD4+ T lymphocyte count (364 vs 512 vs 514 cells/µl; p = 0.0009) was significantly lower in HIV/HBV co-infection compared to HIV/HCV and HIV mono-infection respectively. There was no significant association between demographic and lifestyle characteristics and risk of HBV and HCV infections in HIV positive and negative subjects except for late diagnosis of HIV and history of sharing razors blades and pins, where increased odds of HIV (+) /HBV and HIV (-)/HBV infection were observed. CONCLUSIONS: The prevalence of HIV (+)/HBV (14.9%), HIV (+)/HCV (4.1%), HIV (-)/HBV (10.0%), and HIV (-)/HCV (12.0%) are high among pregnant women in the Brong Ahafo Region of Ghana. HIV/HBV is associated with reduced CD4+ T lymphocyte count but not HIV-1 viral load. Early diagnosis of HIV and intensification of routine antenatal HBV and HCV are essential to abate the risk of maternal to child transmission.

High-Sensitivity C-Reactive Protein: A Potential Ancillary Biomarker for Malaria Diagnosis and Morbidity.

BACKGROUND: Malaria remains an important cause of morbidity and mortality in Africa. Previous studies that assessed C-reactive protein (CRP) have centered on the conventional method. This study evaluated the usefulness of high-sensitivity CRP (hs-CRP) in malaria diagnosis and morbidity in a pediatric population in Ghana. METHODOLOGY: A total of 267 subjects (100 microscopically proven nonmalarial parasitaemics as controls and 167 plasmodium parasitaemic subjects as cases), between the ages of 7 months and 18 years, were recruited for this case-control study. Blood samples were collected for malaria parasite density by microscopic examination; full blood count, electrolytes, and liver function tests using an automated analyzer; and hs-CRP levels by sandwich ELISA method. RESULTS: The median hs-CRP concentration was lowest in the control group and increased significantly from low to high parasitaemia. The median hs-CRP level was significantly higher in high malaria parasitaemia compared to moderate and low malaria parasitaemia. Increasing hs-CRP cutoff (3.12-4.64 mg/L) presented with increasing specificity (79.3-93.1%) and sensitivity (96.4%-97.4%), except for moderate parasitaemia where a decline in sensitivity (80.9%) was observed. However, hs-CRP had relatively lower PPV but high NPV at low parasitaemia while both the PPV and NPV were moderate in moderate parasitaemia. CONCLUSION: hs-CRP yielded a high sensitivity, specificity, and accuracy for low, moderate, and high-grade malaria, respectively, and thus may serve as an effective supplementary diagnostic and prognostic biomarker for Plasmodium parasite infection. However, hs-CRP might not be readily useful yet for diagnostic purposes in hospitals due to the relatively low PPV and NPV for low and moderate parasitaemia and thus necessitates further studies in larger cohorts.

Predominant Complications of Type 2 Diabetes in Kumasi: A 4-Year Retrospective Cross-Sectional Study at a Teaching Hospital in Ghana.

Background and objectives: Diabetes mellitus type 2 (T2DM) has been associated with several microvascular and macrovascular complications. However, studies regarding the predominant complications of T2DM in Ghana have not been conducted. This study evaluated the prevalence and predominant complications of T2DM and assessed the sociodemographic factors associated with the development of diabetes-related complications in Kumasi, Ghana. Materials and Methods: This was a retrospective cross-sectional study conducted at Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. A total of 1600 Ghanaian T2DM adults were included in this study. Patients' clinical data from 2012 to 2016 were retrieved from the hospital's archive. Results: The prevalence of macrovascular and microvascular complications of T2DM was 31.8% and 35.3% respectively. The prevalence of neuropathy, nephropathy, retinopathy, sexual dysfunction, diabetic keto-acidosis (DKA), and hypoglycemia were 20.8%, 12.5%, 6.5%, 3.8%, 2.0%, and 0.8% respectively. Sexual dysfunction was significantly associated with the male gender compared to females. Being employed: Informal (aOR = 0.479, p < 0.0001), and Formal (aOR = 0.475, p = 0.0008) was associated with lower age- and sex-adjusted odds of developing T2DM-related complications while having T2DM for 5-10 years (aOR = 1.550, p = 0.0009) and more than 10 years (aOR = 2.755, p < 0.0001) was associated with increased odds of developing complications. Conclusions: Microvascular complication is the most predominant among T2DM in Kumasi, Ghana. The most prevalent T2DM-related microvascular complication in Kumasi, Ghana is neuropathy. Sexual dysfunction is associated with male compared to female T2DM patients. Being employed reduces the chance of developing T2DM-related complications while increasing DM duration increases the risk of complications.
