Sexual Violence Against Female Students in Polytechnics in South-West Nigeria

Sexual violence against women is a social vice that affects females in diverse forms across clime, race and religion. This manifests through sexual assault, rape, sexual harassment, incest, sexual exploitation, stalking and cyber stalking. Out of all these, sexual assault, rape and sexual harassment of female students by male lecturers are common in the tertiary institutions. There is no doubt that sexual violence is indeed a global problem, but it becomes worrisome when lecturers now demand sex  from their female students   in return for good grades in their courses. This educational epidemic erodes academic integrity and dignity, thus making certification an exercise in falsehood. This study investigated the causes of sexual violence against female students by male lecturers in polytechnics, the consequences of the act on the victims as well as the polytechnic system; and how the horrid act can be controlled in South–West Nigeria. The six states that make up this axis are: Oyo, Osun, Ondo, Ogun, Lagos and Ekiti. The sampled population comprised 1800 female students and 900 adults-both male and female, selected from 17 Federal, State and Private Polytechnics in the six states. The purposive sampling technique was used to select the female students, the adults as well as the polytechnics that participated in the study. The responses were collated and analysed using simple frequencies and percentages because the study was a descriptive survey research. The study revealed that sexual violence against female students was a reality in polytechnics in South-West Nigeria. The male lecturers who indulged in the act did so mainly, to exercise their power and authority over the female students. To control the callous act, some punitive and preventive measures were recommended. These will enable all members of the various academic communities to perceive sexual violence as an inhuman act which every sane person should avoid.

Soil weight determination for optimal growth and yield performances of pot-grown maize

Root restriction, reduced growth and poor yield due to an insufficient quantity of soil are the major limitations of pot-grown maize (Zea mays L.). Hence, to determine the actual quantity of soil required for optimal growth and yield performances of pot-grown maize, two maize varieties; BR9943 DMR-SR (yellow) and BR9928 DMR-SR (white), were evaluated in pots of 5, 10, 20, 30 and 40 kg of topsoil in a 2 x 4 factorial (r = 4) using complete randomised design at the Institute of Agricultural Research and Training, Ibadan, Nigeria. Data were collected on plant height (PHT), leaf area (LA), cob length (CBT), number of kernels per row (K/R), number of rows per cob (R/C), number of kernels per cob (K/C) and total grain weight (TGW). The results obtained showed that all the evaluated parameters were significantly different at P < 0.05 across the soil weights. Maize planted in 30 kg of soil had the highest LA (774.25 cm2), R/C (15.25), K/C (405.62) and TGW (73.84 g), compared with maize planted in 5 kg and 10 kg soils. Plant height and CBT were highest when 40 kg of soil was used. The maize varieties BR9928 DMR-SR (yellow) and BR9943 DMR-SR (white) were not significantly different across the growth and yield parameters except for LA, where the yellow maize (651.91 cm2) had a substantially higher LA than the white maize variety (588.19 cm2). Based on the results of this study, 30 kg of topsoil is recommended for optimum growth and yield performances of pot grown maize

Urinary Pathogens and Their Antimicrobial Susceptibility in Patients with Indwelling Urinary Catheter

The indwelling urinary catheter (IUC) is the most significant risk factor for developing nosocomial urinary tract infections (UTIs). In order to determine the spectrum of bacterial etiology and antibiotic resistance pattern of uropathogens causing catheter associated UTI, a convenient sample size of ninety-two (92) patients on urethral catheter was investigated. Ethical approval for the study was obtained from the OAUTHC research and ethical committee. Catheter stream urine samples were obtained from all patients and cultured on appropriate culture media. Suspected isolates were identified by a combination of standard tests and using MICROBACT GNA12A/B/E. Susceptibility of the isolates against thirteen (13) antibiotics was performed by the disc diffusion method. Significant bacteriuria was observed in 60.9% (56) catheter specimen urine (CSU) received, while 39.1% (36) were culture negative. Of the 56 positive culture, the predominant organisms were Klebsiella oxytoca, 28.6 %( 16), Proteus vulgaris, 23.2% (13) and Staphylococcus aureus, 12.5% (7). Overall, the antimicrobial susceptibility results showed that all the isolates were highly resistant to the antibiotics tested. Over 50% resistance was recorded for trimethoprim/sulfamethoxazole, gentamicin and amoxicillin/clavulanic acid. More than 25% of the isolates were resistant to nitrofurantoin. This study indicates that catheter stream UTI caused by multiply resistant bacteria are common in our hospital. There is a need to establish standard guidelines on the care of catheter for all units in the hospital with a view to preventing nosocomial infections associated with the use of the catheter in patients. We also advocated prudent use of antibiotics. Key words: Antibiotic resistance, Urinary catheter, Uropathogens, Urinary tract infectio

Challenges experienced by women caregivers of orphans and vulnerable Children in KwaDlangezwa, Kwazulu Natal

Abstract: Women caregivers are a major driving force when it comes to survival of orphans and vulnerable children worldwide. Despite their huge contributions to socio-economic development, many caregivers are faced with enormous challenges due to the demand of their work. This study examined challenges facing women caregivers in KwaDlangezwa, a university community located in the KwaZulu Natal Province of South Africa. The study employed the descriptive research design of a survey type. Qualitative method of data collection was used to interview ten (10) women who are caregivers of orphans and vulnerable children in the community. Findings of the study revealed issues such as health and well-being, insecurity, inadequate resources and bad influence brought by the university students in the community and how women caregivers are coping with these issues in their day-to-day caregiving responsibilities. The roles of caregivers in providing health and social care to orphans and vulnerable children are enormous. All stakeholders in community development and social welfare must team up to introduce interventions towards caring for the low-income caregivers, especially those that provide care for orphans and vulnerable children in rural communities

Kigelia africana Stem Bark, Fruit and Leaf Extracts Alleviate Benzene-induced Leukaemia in Rats

Aims: This study was aimed at evaluating the potential leukaemia chemotherapeutic activities of various extracts of Kigelia africana stem bark; fruit and leaf by using a benzene-induced model of leukaemia to validate its folkloric use. Evidences from African herbal medicine and traditional applications have shown that Kigelia africana plant has several beneficial therapeutic properties against microbial infections and cancer cell lines. Study Design: Experimental study. Place and Duration of Study: Department of Biomedical Science, College of Health Sciences, Ladoke Akintola University of Technology, Osogbo, Nigeria and study was conducted between August, 2016 and November, 2016. Methodology: Rats were administered 0.2 mL of benzene solution intravenously through the tail 48-hourly for 4 weeks, tested periodically and observed till leukaemia developed prior to treatment with respective extract of the Kigelia africana stem bark, fruit and leaf in appropriate rat groups after leukaemia was confirmed with haematological protocols. Leukaemic rats were administered with 100 mg/mL contained in 0.5 mL stem bark, 0.5 mL fruit and 0.2 mL of the leaf extract orally by gavage using oral cannula once daily post leukemia induction for four weeks. Haematological parameters and white blood cells differential counts (lymphocytes) were assessed in both control and treatment groups to determine the leukaemia burden. Results: Kigelia africana treatment using the stem bark, fruit and leaf significantly (P < 0.05) alleviated the anaemia indices and reduced the marked leucocytosis usually associated with leukaemia toward the negative control level when compared with the leukaemia control group. Antileukaemic activity however appears to be highest in stem bark, and least in the leaf. Conclusion: This study revealed the potential of ethanol extracts of Kigelia africana stem bark, fruit and leaf to reverse leukaemic effects in benzene-induced leukaemia bearing wistar rats and this suggest that the extracts might be promising natural, non-toxic and anticancer agents

Chemical, antioxidant and sensory properties of pasta from fractionated whole wheat and Bambara groundnut flour

Pasta from whole-grain wheat is highly nutritious but has poor sensory properties. Hence, this study prepared pasta from fractionated whole-grain wheat flour enriched with 20% Bambara groundnut. The chemical, antioxidant and sensory properties of the pasta were assessed using standard methods. The fat, protein, ash contents, lightness and antioxidant properties value of the flour and pasta increased, while carbohydrate and fibre contents decreased with a reduction in particle size from 500 μm to 112 μm. Potassium (246.50–249.00 mg/kg), calcium (223.50–254.00 mg/kg) and magnesium (184.50–192.00 mg/kg) were the major mineral element in the pasta samples, while zinc (1.00–2.00 mg/kg) and iron (3.50–13.00 mg/kg) are present in small quantities. The optimum cooking time of pasta (average 6.55 min) from the fractionated flours was shorter compared to the control pasta (pasta made from unfractionated wheat flour), but the cooking loss was not significantly affected. Pasta from flour with particle sizes of 300 and 112 μm were very similar in their sensory attributes and showed the highest ratings in overall acceptability. Fractionation of whole-grain wheat flour seems very promising in producing pasta with fairly good antioxidant potentials and high level of protein and fibre to improve the health of pasta-loving individuals.The Faculty of Science-University Research Committee Fellowship of the University of Johannesburg, South Africa.http://www.elsevier.com/locate/lwthj2022Consumer ScienceFood Scienc

Reduced TRPC Channel Expression in Psoriatic Keratinocytes Is Associated with Impaired Differentiation and Enhanced Proliferation

Psoriasis is a characteristic inflammatory and scaly skin condition with typical histopathological features including increased proliferation and hampered differentiation of keratinocytes. The activation of innate and adaptive inflammatory cellular immune responses is considered to be the main trigger factor of the epidermal changes in psoriatic skin. However, the molecular players that are involved in enhanced proliferation and impaired differentiation of psoriatic keratinocytes are only partly understood. One important factor that regulates differentiation on the cellular level is Ca2+. In normal epidermis, a Ca2+ gradient exists that is disturbed in psoriatic plaques, favoring impaired keratinocyte proliferation. Several TRPC channels such as TRPC1, TRPC4, or TRPC6 are key proteins in the regulation of high [Ca2+]ex induced differentiation. Here, we investigated if TRPC channel function is impaired in psoriasis using calcium imaging, RT-PCR, western blot analysis and immunohistochemical staining of skin biopsies. We demonstrated substantial defects in Ca2+ influx in psoriatic keratinocytes in response to high extracellular Ca2+ levels, associated with a downregulation of all TRPC channels investigated, including TRPC6 channels. As TRPC6 channel activation can partially overcome this Ca2+ entry defect, specific TRPC channel activators may be potential new drug candidates for the topical treatment of psoriasis

Application of GIS in public health practice: a consortium’s approach to tackling travel delays in obstetric emergencies in urban areas

Geographic Information System (GIS) has become an effective and reliable tool for researchers, policymakers, and decision-makers to map health outcomes and inform targeted planning, evaluation, and monitoring. With the advent of big data-enabled GIS, researchers can now identify disparities and spatial inequalities in health at more granular levels, enabling them to provide more accurate and robust services and products for healthcare. This paper aims to showcase the progress of the On Tackling In-transit Delays for Mothers in Emergency (OnTIME) project, which is a unique collaborative effort between academia, policymakers, and industrial partners. The paper demonstrates how the limitations of traditional spatial accessibility models and data gaps have been overcome by combining GIS and big data to map the geographic accessibility and coverage of health facilities capable of providing emergency obstetric care (EmOC) in conurbations in Africa. The OnTIME project employs various GIS technologies and concepts, such as big spatial data, spatial databases, and public participation geographic information systems (PPGIS). We provide an overview of these concepts in relation to the OnTIME project to demonstrate the application of GIS in public health practice

Associated risk factors of STIs and multiple sexual relationships among youths in Malawi

Having unprotected sex with multiple sexual partners (MSP) is the greatest risk factor for human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) among youths. Young people with MSPs are less likely to use a condom and the greater the risk for STIs. This study examines the associated risk factors of STIs and multiple sexual partnerships among youths aged 15–24 years. The Malawi Demographic Health Survey 2010 data was used. Out of a sample of 2,987 males and 9,559 females aged 15–24 years, 2,026 males and 6,470 females were considered in the study. Chi square test and logistic regression techniques were performed. Analysis was performed using Statistical Package for Social Sciences (SPSS) version 22.Article writing fellowships were received from the Research Development Office, University of the Western Cape, 7535 Bellville, Cape Town, South Africa.Web of Scienc
