The Pattern and Presentation of Stroke in Federal Teaching Hospital Abakaliki (FETHA) South-East Nigeria

Stroke is a common neurologic disorder and it is the third leading cause of mortality worldwide after ischaemic heart disease and cancer. Males are predominantly affected and ischaemic stroke is more prevalent than haemorrhagic stroke. This study determined the pattern and presentation of stroke in Federal Teaching Hospital Abakaliki (FETHA) South-East Nigeria. It was a retrospective, descriptive and hospital based study. The stroke register of the neurology unit was reviewed and relevant data were extracted and analyzed using Statistical Package for Social Sciences (SPSS) version 19 software. The sex ratio was M:F =3:2 and  the peak age prevalence of stroke was the 7th decade. Ischaemic stroke was present in 65%, while intracerebral haemorrhage and subarachnoid haemorrhage were 31% and 4% respectively. Stroke constituted 12% of medical deaths with 30 day case mortality rate of 15%. Stroke is highly prevalent in Abakaliki south east Nigeria. The 30 day case mortality rate is relatively low in this study. There should be regular public enlightenment for stroke prevention and prompt referral of stroke patients to a stroke unit for adequate management.

Pattern of Medical Admissions in a Tertiary Health Centre in Abakaliki South-East Nigeria

The pattern of medical admissions varies amongst different regions of the world and this depends on many factors including the prevalent medical diseases in the region. This study determined the pattern of medical admissions in a tertiary health centre in Abakaliki South Eastern Nigeria and compared it with that from other parts of the country.   It was a retrospective, descriptive and hospital based study. The admission and discharge registers of the medical wards of the Federal Teaching Hospital Abakaliki south-east Nigeria from July 2012 to June 2013 were reviewed and relevant data extracted and analyzed using Statistical Package for Social Sciences (SPSS) version 19 software.  The patients admitted during the period numbered 1247, with age range of 15 to 99 years. There were 643(51.56%) males and 604 (48.44%) females, with a male to female ratio of 1.06:1. Seventy per cent of the patients were between 30 and 69years. Infectious diseases accounted for 255 (20.45%) of the admissions, while cardiovascular disorders and neurological disorders accounted for 251 (20.13%) and 233 (18.68%) respectively. Non-communicable diseases accounted for 711 (57.02%) of the cases while communicable diseases accounted for 536 (42.98%). There was male predilection for neurological and chronic liver diseases while female patients had predilection for infectious diseases. The study showed that majority of the patients was in the productive age. There was also double burden of both communicable and non-communicable diseases in Abakaliki with higher female prevalence of infectious diseases. Health planning towards prevention of the identified diseases should be instituted. Keywords: pattern, medical, admissions, Abakaliki, Nigeri

HYPOGLYCAEMIC AND HAEMATINIC PROPERTIES OF ETHANOL LEAF EXTRACT OF ARTOCARPUS HETEROPHYLLUS IN ALLOXAN INDUCED DIABETIC RATS.

Background: Anaemia is known to be associated with diabetes; moreover, with the increasing cases of diabetes there is need for the use of more affordable alternative herbal medicines for the treatment of diabetes and anaemia. The aim of this work was to evaluate the hypoglycaemic and haematinic properties of Artocarpus heteropyllus on diabetic rats. Materials and Methods: Ethanol leaf extract of Artocarpus heteropyllus was screened for phytochemicals and its acute toxicity was tested on mice. Induction of diabetes was done at a dose of 150 mg/kg body weight (b.w) (with exception of the control group). The extract was administered to rats for a period of 7 days at 100, 300 and 500 mg/kg b.w, respectively, following induction. Blood samples of rats were tested for fasting blood sugar (FBS), packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC), haemoglobin, neutrophil lymphocyte and eosinophil counts. Results: The ethanol leaf extract of A. heterophyllus showed no mortality up to a dose of 5000 mg/kg b.w. Administration of the extract to diabetic rats resulted in a decrease in the FBS of diabetic rat, and significant increases (p< 0.05) in RBC, PCV, WBC and haemoglobin levels. Conclusion: The ethanol leaf extract of A. heterophyllus increased the haematological indices of diabetic rats. Our findings support the use of this plant as an herbal alternative in the treatment of diabetes and anaemia associated diabetes

Cucumeropsis mannii seed oil ameliorates Bisphenol‐A‐induced adipokines dysfunctions and dyslipidemia

From Wiley via Jisc Publications RouterHistory: received 2022-12-25, rev-recd 2023-01-07, accepted 2023-02-06, pub-electronic 2023-02-18Article version: VoRPublication status: PublishedThis study demonstrated the therapeutic potentials of Cucumeropsis mannii seed oil (CMSO) capable of alleviating BPA‐induced dyslipidemia and adipokine dysfunction. In this study, we evaluated the effects of CMSO on adipokine dysfunctions and dyslipidemia in bisphenol‐A (BPA)‐induced male Wistar rats. Six‐week‐old 36 albino rats of 100–200 g weight were assigned randomly to six groups, which received varied doses of BPA and/or CMSO. The administration of BPA and CMSO was done at the same time for 42 days by oral intubation. The adipokine levels and lipid profile were measured in adipose tissue and plasma using standard methods. BPA induced significant (p < .05) increases in triglycerides, cholesterol, leptin, LDL‐C, and atherogenic and coronary risk indices in adipose tissue and plasma, as well as a decrease in adiponectin and HDL‐C levels in Group II animals. BPA administration significantly (p < .05) elevated Leptin levels and reduced adiponectin levels. BPA plus CMSO reduced triglycerides, cholesterol, leptin, LDL‐C, and atherogenic and coronary risk indices while increasing adiponectin levels and HDL‐C in adipose tissue and plasma (p < .05). The results showed that BPA exposure increased adipose tissue as well as serum levels of the atherogenic index, triglycerides, cholesterol, coronary risk index, LDL‐C, leptin, and body weight with decreased adiponectin levels and HDL‐C. Treatment with CMSO reduced the toxicities caused by BPA in rats by modulating the body weight, adiponectin/leptin levels, and lipid profiles in serum and adipose tissue. This study has shown that CMSO ameliorates BPA‐induced dyslipidemia and adipokine dysfunctions. We suggest for further clinical trial to establish the clinical applications

Spectroscopic and deep learning-based approaches to identify and quantify cerebral microhemorrhages.

Cerebral microhemorrhages (CMHs) are associated with cerebrovascular disease, cognitive impairment, and normal aging. One method to study CMHs is to analyze histological sections&nbsp;(5-40&nbsp;μm) stained with Prussian blue. Currently, users manually and subjectively identify and quantify Prussian blue-stained regions of interest, which is prone to inter-individual variability and can lead to significant delays in data analysis. To improve this labor-intensive process, we developed and compared three digital pathology approaches to identify and quantify CMHs from Prussian blue-stained brain sections: (1) ratiometric analysis of RGB pixel values, (2) phasor analysis of RGB images, and (3) deep learning using a mask region-based convolutional neural network. We applied these approaches to a preclinical mouse model of inflammation-induced CMHs. One-hundred CMHs were imaged using a 20 × objective and RGB color camera. To determine the ground truth, four users independently annotated Prussian blue-labeled CMHs. The deep learning and ratiometric approaches performed better than the phasor analysis approach compared to the ground truth. The deep learning approach had the most precision of the three methods. The ratiometric approach has the most versatility and maintained accuracy, albeit with less precision. Our data suggest that implementing these methods to analyze CMH images can drastically increase the processing speed while maintaining precision and accuracy

Cucumeropsis mannii seed oil protects against Bisphenol A‐induced testicular mitochondrial damages

Abstract There has been increasing search for the ameliorative properties of seed oils against toxicants. bisphenol A acts as an estrogenic endocrine‐disrupting chemical capable of causing male infertility. This study aimed to explore Cucumeropsis mannii seed oil effects against mitochondrial damage in rats using bisphenol A. Forty‐eight rats were randomly assigned to six groups (n = 6) of eight rats each and fed the same food and water for 6 weeks. The group A rats were given 1 mL olive oil, while the ones in group B were given bisphenol A at 100 mL/kg body weight via oral route. Group C received C. mannii seed oil 7.5 mL/kg body weight C. mannii seed oil, while group D, group E, and group F were pre‐administered bisphenol A at 100 mL/kg body weight, followed by treatment with C. mannii seed oil at 7.5, 5, and 2.5 mL/kg body weight, respectively. Antioxidant enzymes, glutathione, reactive oxygen species, testicular volume, malondialdehyde, body weight, and testicular studies were done using standard methods. The results of the bisphenol A‐administered group showed a significant decrease in the antioxidant enzymes, glutathione, body weight, and testicular volume with elevation in the levels of reactive oxygen species, malondialdehyde, and testicular indices. BPA + CMSO‐treated group showed a significant increase in GPx activity compared with BPA‐exposed rats. CMSO treatment significantly increased catalase activity in comparison with that of rats exposed to BPA. Remarkably, C. mannii seed oil and bisphenol A co‐administration significantly reversed the abnormalities observed in the dysregulated biochemical biomarkers. Our findings suggest that C. mannii seed oil has considerable antioxidant potential which can be explored in therapeutic development against systemic toxicity induced by exposure to bisphenol A.
