The Conception of ‘Sex’ and ‘Gender’ as Background to Inequities Faced by Women

This paper takes a social constructionist perspective to explain how dominant constructions of ‘sex’ and ‘gender’ built upon deeply embedded substructure of gender differences and the expected roles of women in the public sphere and in private domain in nearly all societies. The paper aims at exploring the argument that sex, like gender, is a socially constructed concept. It examines the construction of sex and gender from various perspectives including the feminist perspectives and those opposing arguments from the biological determinist point of view. Next, the paper discusses an aspect of the normative construction of sex/gender as proposed by the post-structuralist school of thought and finally examines some cultural implications of the conventional understanding of sex. The paper concludes that sex is strongly influenced by social       factors, ideas and other socio-cultural contexts including the norms, values and beliefs embedded in different societies, along with some traditional practices

Inoculation and amendment strategies influence switchgrass establishment in degraded soil

Bioenergy feedstock production on degraded land can serve as a means for modulating land competition for food versus energy. Due to little or no agricultural value of degraded soil, fortification of the soil with an organic amendment or inoculum will improve biomass productivity. However, as farmers struggle to rejuvenate their degraded land, there is a need for a quick screening strategy to select the best method of enhancing cellulosic (switchgrass, SG) biomass production in degraded soil. The goal of this study is to evaluate the effects of soil amendment and inoculation strategies on biomass productivities of SG in a reclaimed surface-mined soil (RMS). Experiments were conducted in the greenhouse using moisture replacement microcosms (MRM) to screen strategies for enhancing biomass productivities of SG in a RMS. Strategies included soil amendment with organic by-products (poultry litter, paper mill sludge, and vermicompost), inorganic nutrients (nitrogen and phosphorus fertilizers), or a commercial preparation of endomycorrhizae fungi (AMF, BioVam). Experiments were implemented with ten (10) treatments with six replicates for each treatment. After eight weeks of incubation in MRM systems, inoculation of RMS with AMF produced the highest aboveground and total biomass (0.9 g and 1.77 g per microcosm container) at p \u3c 0.05. The total biomass of commercial AMF significantly (p \u3c 0.05) outperformed all other treatments in the order of AMF \u3e AMF + VC \u3e PMS + N \u3e VC = PMS = PL \u3e PMS + AMF \u3e N + P \u3e ASL \u3e Control. This microcosm screening experiment served as a quick screening to establish that soil enhancement and inoculation strategies can enhance biomass productivities of SG in degraded soil

Knowledge, attitude, and utilization of HIV counseling and testing by female sex workers in Lagos State, Nigeria

Objectives: The Human Immunodeficiency Virus (HIV) epidemic continues to expand among female sex workers (FSWs) who have limited access to and utilization of HIV counseling and testing services (HCT). HCT plays a pivotal role in increasing knowledge and awareness to prevent, treat, and control HIV/AIDS. The study objective was to determine the knowledge, attitude, utilization of HCT among brothel-based FSWs (BBFSWs). Method: This was a descriptive cross-sectional study among 300 BBFSWs in Lagos State. The respondents were recruited by snowballing after a multistage sampling method was used in the selection of the brothels. The data was collected using an adapted interviewer-administered questionnaire and analyzed using IBM SPSS Statistics version 23. The level of statistical significance was set at p<0.05. Results: Majority (63.0%) of the respondents were between the ages of 21-30 years and 67.4% had good knowledge of HIV and HCT. About 75.0% had a positive attitude towards HCT and 55.6% of FSWs in this study had utilized an HCT center in the past. The main reason for not taking HIV test was the fear of a positive result (90.6%) while the main reasons given for not visiting any HCT center were lack of confidentiality (13.3%), stigmatization (14.8%), and distance to the HCT center (67.2%). Conclusion: There was a good knowledge of HCT and a positive attitude towards HCT services by the respondents. The main reasons for not taking the HIV test as indicated by respondents were fear of a positive result. HIV-stigma related issues should be adequately addressed

Haematological Indices of Broiler Chickens Administered Water Containing Medicinal Plant Leaf Methanol Extract

The discovery that the use of antibiotics in animal production is fueling the increasing problem of transmitting resistance bacteria from food animals to man has led to the search for an alternative to the use of antibiotics. Therefore, the response of broiler chickens fed various medicinal plants methanol extract as a replacement for antibiotics was investigated. The plant extracts encompass four available leaves; Gercinia kola (Bitter Kola), Alchornea cordifolia (Christmas bush), Pterocarpus santalinoides (Red scandal wood) and Chromolera Odorata (Hagony or Siam weed). A total of 180 unsexed Ross strain broiler chickens were randomly assigned to these dietary treatments which had 30 birds each. The treatments were replicated thrice with 10 birds per replicate in a Completely Randomized Design (CRD). Feed and water were provided ad libitum throughout the experiment which lasted for 56 days. Haematological indices of broiler chickens were evaluated. Significant differences (p<0.05) were observed in the mean values of all the hematological parameters measured across the treatment groups, except Packed cell volume and White blood cell. The result values obtained in this present study were within the standard range of PCV of normal birds with the reference range of 25.0 - 45.0%. However, the values obtained did not reveal any health problem. The findings of this study conclude that the medicinal plant methanol extracts have considerable potentials as component of broiler chicken diet. Alchornea cordifolia plant methanol extract can successfully be used to replace antibiotics at 1g/litre of drinking water for broiler production. Further research should be carried out on Alchornea cordifolia and other medicinal plants to examine their potentials and inhibitory characteristics

Clinical characterisation and management outcomes of COVID-19 infection in pregnancy in a Nigerian tertiary hospital

Background: Literature on the antenatal and perinatal management and outcomes of COVID-19 infection in pregnancy in Nigeria and sub-Saharan Africa is gradually emerging but sparse. There is an urgent need to build up the knowledge base of COVID-19 infection in Nigerian pregnant women. The objective of the current study was to determine the clinical characteristics and management outcomes of COVID-19 infection in pregnancy at the Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Nigeria.Methods: A one-year retrospective review of all cases of COVID-19 infection in pregnancy managed at the OAUTHC. Relevant data were extracted from the case records of all cases managed using a purpose-designed proforma. Data collected was analysed using IBM-SPSS, version 24. Associations between categorical variables were assessed using chi square, with level of significance set at <0.05.Results: A total of 22 cases were managed. Majority (15, 68.2%) of the women were either asymptomatic or had mild symptoms. The commonest symptom was cough (8, 36.4%). The mean duration of admission was 6.6±4.2 days. The most common maternal and perinatal complication was preterm delivery/birth (3, 13.6%). There was no maternal mortality. The mean birth weight of the babies was 3226g±597g, with mean 1- and 5- minutes Apgar scores of 8.0±1.3 and 9.5±0.6 respectively.Conclusions: Although COVID-19 infection in pregnancy is an asymptomatic or mild infection in the majority of cases in Ile-Ife, Nigeria, it is associated with adverse maternal and perinatal outcomes. Further studies are recommended to determine transplacental transmission of COVID-19 infection and antibodies

Phytochemical s creening and a ntibacterial a ctivities of Tectona grandis L. f. (Teak) l eaves on m icroorganisms i solated from d ecayed f ood s amples

Bacteria were isolated from decayed food samples (tomatoes, cooked beans and rice) collected from Afe Babalola University, Ado Ekiti (ABUAD) cafeteria and characterized. Some of these isolated microorganisms could pose serious har m to humans including animals and they are normally treated with commercial antibiotics. However, the majority of bacteria are resistant to many antibiotics therefore, the use of plant extracts with therapeutic potential against resistant bacteria is neces sary. In this investigation, eight bacteria were isolated from decayed food samples. The bacterial isolates were identified as Bacillus cereus and B. siamensis from rice sample; Klebsiella oxytoxa , Salimicrobium halophilium and Norcardia brasiliensis from beans sample; Bacillus subtilis , Enterobacter taylore , and Brevibacillus agri from tomatoes. The leaf samples of Tectona grandis were screened qualitatively and quantitatively for the phytochemicals while the crude methanol and chloroform extracts were used as antimicrobial agents against the isolated microorganisms. Alkaloids, carotenoids and tannins were present in large amount. T he bacterial isolates were more susceptible to commercial antibiotics than that of methanol extracts of T. grandis . The methanol extracts of T. grandis have a higher antimicrobial activity than the chloroform ext ract

The Association between Individual and Combined Components of Metabolic Syndrome and Chronic Kidney Disease among African Americans: The Jackson Heart Study

Introduction: Approximately 26.3 million people in the United States have chronic kidney disease and many more are at risk of developing the condition. The association between specific metabolic syndrome components and chronic kidney disease in African American individuals is uncertain. Methods: Baseline data from 4,933 participants of the Jackson Heart Study were analyzed. Logistic regression models were used to estimate the odds and 95% confidence intervals of chronic kidney disease associated with individual components, metabolic syndrome, the number of components, and specific combinations of metabolic syndrome components. Results: Metabolic syndrome was common with a prevalence of 42.0%. Chronic kidney disease was present in 19.4% of participants. The prevalence of metabolic components was high: elevated blood pressure (71.8%), abdominal obesity (65.8%), low fasting high density lipoprotein cholesterol (37.3%), elevated fasting glucose (32.2%) and elevated triglycerides (16.2%). Elevated blood pressure, triglycerides, fasting blood glucose, and abdominal obesity were significantly associated with increased odds of chronic kidney disease. Participants with metabolic syndrome had a 2.22-fold (adjusted odds ratio (AOR) 2.22; 95% CI, 1.78–2.78) increase in the odds of chronic kidney disease compared to participants without metabolic syndrome. The combination of elevated fasting glucose, elevated triglycerides, and abdominal obesity was associated with the highest odds for chronic kidney disease (AOR 25.11; 95% CI, 6.94–90.90). Conclusion: Metabolic syndrome as well as individual or combinations of metabolic syndrome components are independently associated with chronic kidney disease in African American adults

Nonalbuminuric Renal Impairment in Type 2 Diabetic Patients and in the General Population (National Evaluation of the Frequency of Renal Impairment cO-existing with NIDDM [NEFRON] 11)

OBJECTIVE Most diabetic patients with impaired renal function have a urinary albumin excretion rate in the normal range. In these patients, the etiology of renal impairment is unclear, and it is also unclear whether this nonalbumunuric renal impairment is unique to diabetes. RESEARCH DESIGN AND METHODS In this study, we examined the frequency and predictors of nonalbumunuric renal impairment (estimated glomerular filtration rate [eGFR] <60 ml/min per 1.73 m(2)) in a nationally representative cohort of 3,893 patients with type 2 diabetes and compared our findings with rates observed in the general population from the Australian Diabetes, Obesity and Lifestyle Study (AusDiab) survey (n = 11,247). RESULTS Of the 23.1% of individuals with type 2 diabetes who had eGFR <60 ml/min per 1.73 m(2) (95% CI 21.8-24.5%), more than half (55%) had a urinary albumin excretion rate that was persistently in the normal range. This rate of renal impairment was predictably higher than that observed in the general population (adjusted odds ratio 1.3, 95% CI 1.1-1.5, P < 0.01) but was solely due to chronic kidney disease associated with albuminuria. In contrast, renal impairment in the absence of albuminuria was less common in those with diabetes than in the general population, independent of sex, ethnicity, and duration of diabetes (0.6, 0.5-0.7, P < 0.001). CONCLUSIONS Nonalbuminuric renal impairment is not more common in those with diabetes. However, its impact may be more significant. New studies are required to address the pathogenesis, prevention, and treatment of nonalbuminuric renal disease

The practice of hepatocellular cancer surveillance in Nigeria

Background: Hepatocellular cancer is a disease of global and public health importance due to the widespread distribution of risk factors and associated high case fatality. Hepatocellular Cancer (HCC) in Sub-Saharan Africa is commonly seen among the younger age groups (&lt;45 years) who present mostly in the terminal stage, when the disease is not amenable to any curative therapy. Hepatocellular Carcinoma surveillance employs the use of simple, cheap and readily available investigations, to detect early curable cancer in individuals with risk factors for HCC.Objectives:The aim of this study is to assess the practice of hepatocellular cancer screening among physicians.Methodolgy:This is a nationwide online survey carried out among physicians who care for patients with HCC. A questionnaire was sent out via a web link to all consenting doctors in Nigeria. The responses were collated in a cloud-based application and data was analysed using Epi-info version 20.Results:Atotal of 218 respondents, 142 were males (65.1 %) with a mean age of 37.6 ± 5.7 years. The modal age group was 31-40 years 153 (69.5%). The main factors considered as a hindrance to surveillance were; the cost of the tests (57.7%), failure of return of patients (50.5%) and not being aware of a surveillance program (45.2 %). The majority of the respondents were Gastroenterologists and Family Physicians. 54% of the gastroenterologists and 64% of the family physicians have never offered HCC surveillance to their patients.Conclusion:This survey highlights a knowledge gap in HCC surveillance among physicians. There is a need to make HCCsurveillance a daily routine among patients at risk by all physicians. Keywords: Surveillance, Hepatocellular Carcinoma, HBV, HCV, Cancer screening
