Impact of polyethylene microplastics exposure on kallikrein-3 levels, steroidal-thyroidal hormones, and antioxidant status in murine model: protective potentials of naringin.

The widespread presence of microplastics in the environment has raised significant concerns regarding their potential impact on human and animal health. Among various microplastic types, polyethylene microplastics (PE-MPs) are particularly prevalent due to the extensive use in packaging and consumer products. Exploring the uncharted therapeutic potentials of naringin, this study delves into its mitigating effects on disruptions in kallikrein-3 levels, steroidal-thyroidal hormone balance, and antioxidant defense triggered by PE-MPs exposure, paving the way for novel interventions in environmental toxin-induced endocrine and oxidative stress disorders. Male Wistar rats (n = 24) were randomly grouped into four: Control, PE-MPs (1.5 mg/kg), PE-MPs + NAR (1.5 mg/kg PE-MPs + 100 mg/kg NAR), and NAR (100 mg/kg). Hormonal and antioxidant parameters were assessed after 28 days of exposure. PE-MPs exposure caused a significant increase(p < 0.005) in the level of kallikrein-3 (KLK-3) while it significantly reduces the levels of testosterone (TST), luteinizing hormone, thyroid stimulating hormone (TSH) and Free-triiodothyronine (fT3) and Total cholesterol (TChol) concentration. PE-MPs exposure also disrupted significantly (p < 0.005) antioxidant profile by down-regulating the activities of glutathione-S-transferase, catalase (CAT), superoxide dismutase (SOD) and reducing levels of glutathione (GSH) and ascorbic acid (AA) while concentration of malondialdehyde (MDA) levels were increased relative to control. However, the mitigating potentials of naringin on disruptions in hormonal and antioxidant profiles caused by PE-MPs exposure were demonstrated, as NAR normalized KLK-3, steroid, and thyroid hormone levels, cholesterol concentration, and enhanced antioxidant defense. This suggests that NAR is a promising protective agent against endocrine and oxidative damage induced by environmental contaminants such as microplastics.

Knowledge, attitude and practice of antenatal mothers toward urinary tract infection in selected health facilities in Ekiti state, Nigeria.

Background: Urinary Tract Infections (UTIs) during gravidity are among the most preponderant contagion globally and can culminate in fetal and maternal mortality. Lack of awareness and poor preventive practices can exacerbate this outcome. This study assessed the knowledge and preventive practices of antenatal mothers' towards UTIs in pregnancy. Design: This was a cross-sectional descriptive survey involving antenatal mothers in selected health care facilities in Ekiti State. Methods: A pre-tested adapted questionnaire was used for data collection. Data was analyzed using descriptive statistics and Chi-square at p < 0.05. Results: The mean respondents' age was 24.6 ± 2.1 years and barely less than half (43.8%) were multigravida. The findings of the study revealed that 64.0% of the respondents had good knowledge of UTIs. Overall, majority (78.9%) of the respondents exhibit good preventive practices toward UTIs in pregnancy, although the prevalence of UTIs among the studied subjects was found to be high (54.1%), with nearly half (48.7%) of the respondents reported been tested once for UTIs in the current pregnancy. Furthermore, there was a statistically significant relationship between educational level and respondents' knowledge on the prevention of UTIs in pregnancy (p = 0.00; p < 0.05). Conclusions: Respondents had good knowledge and good preventive practices toward UTIs. However, the high prevalence of UTIs reported among respondents justifies the need for implementation of knowledge enhancement program, routine testing and prompt treatment of UTIs among antenatal mothers.

Environmental toxicants and health adversities: A review on interventions of phytochemicals.

Toxicity arising from environmental contaminants has attracted global interest in the last few decades, due to the high morbidity and mortality associated with them. Efforts have been made to combat the consequential outcomes of environmental toxicity in humans through traditional remediation techniques and therapeutic measures which have been hampered by one or more limitations. Consequently, this scenario has triggered interest in the medicinal properties of phytochemicals. Thus, this review gives a succinct and in-depth elucidation of the various environmental contaminants and their toxicity effects on humans. It delves into the various classes of phytochemicals and their intervention roles. The study adopted a desk review of existing literatures from scientific reports and peer reviewed articles through triangulation of data sources. "Phytochemicals" are group of secondary metabolites obtained from plants with medicinal properties. These groups of compounds are included but not limited to flavonoids, tannins, saponins, alkaloids, cardenoloids, terpenoids, and phytosteroids. This review corroborates the prophylactic and therapeutics efficacy of these phytochemicals as anti-metastatic, anti-inflammatory, anti-aging, anti-oxidant, anti-microbial and live saving substances with empirical findings from several laboratory, clinical trials and epidemiologic studies. It conclude that given the wide range of medicinal properties of phytochemicals, there is an urgent need for its full optimization in the pharmaceutical industry and future studies should focus on identifying the bioactive molecules in these compounds and its effectiveness against mixer toxicity.

Traditional birth attendants' knowledge, preventive and management practices for postpartum haemorrhage in Osun State, Southwestern Nigeria.

Traditional birth attendants (TBAs) have become an integral part of the workforce providing delivery services in Nigeria due to the limited number of skilled birth attendants and cultural preferences. This study assessed the knowledge, management and preventive practices regarding postpartum haemorrhage (PPH) among TBAs in selected communities in Osun State, Southwest Nigeria. The study employed a descriptive cross-sectional study design and recruited 260 TBAs in four communities in Osun State. Data were collected by means of an adapted semi-structured questionnaire. Data were analysed using SPSS version 23 and summarized using descriptive and inferential statistics (chi-square and logistic regression) with the level of significance set at p < 0.05. The findings indicated that most (71.4%) of the TBAs were cleric, while others were herbalist (28.6%). Although the majority (76.4%) of the TBAs had good knowledge of the causes and warning signs of PPH, a high percentage (69.3%) of TBAs had poor management practices, while 114 (64.1%) TBAs had inadequate preventive practices. Notably, almost none of the participants practised active management of the third stage of labour; the majority of TBAs did not administer any uterotonic drugs to the mother, nor did they deliver the placenta by controlled cord traction. Gender (P = 0.029), educational level (P = 0.035) and average number of births per month (P = 0.001) significantly influenced TBAs' management practices. Similarly, the TBA type (P < 0.001), average number of births per month (P = 0.003) and experience with formal training (P = 0.005) showed significant associations with TBAs' preventive practices. Furthermore, TBAs' preventive practices towards PPH were influenced by the TBA type (OR: 4.23; 95% CI 1.64-10.90). TBA management practices were also influenced by the TBA type (OR: 4.42; 95% CI 2.03-9.61). Traditional birth attendants in this study had poor management and poor preventive practices for postpartum haemorrhage.

Predictors of exclusive breastfeeding practice among nursing mothers attending a health care facility in a peri-urban setting in Lagos State, Nigeria.

Background: The Nigerian government initiated various national infant and young child feeding programmes (1992-2005) to improve juveniles well-being. Despite these efforts, under-five children feeding related diseases and mortality still escalate. Investigating the drivers of exclusive breastfeeding (EBF) is exigent in tackling this menace. Objective: To investigate maternal socio-demographic and index child variables that serve as predictors of EBF practice among nursing mother attending a healthcare facility in Lagos, western Nigeria. Methods: One hundred and twenty (N=120) consenting nursing mothers (15-49 years) with infants between 0-24 months completed a structured, self-administered questionnaire. Scores of current practice level for EBF was computed and adjusted odd ratios (aORs) generated from a logistic regression model. Results: Respondents mean age was 28.7 ± 2.3 years. Of 120 respondents, 82(68.3%) and 38(31.7%) had good and poor EBF practice respectively. Having an index child <6months age (aOR=5.02, 95% confidence intervalCI=1.28-15.43), being in monogamy (aOR=3.0, 95% CI=1.80-6.73), having tertiary education (aOR=3.12, 95% CI=1.39-8.96), being married (aOR=2.0, 95% CI=0.1-0.8) and vaginal delivery (aOR=2.96, 95% CI=1.75-7.48) increased the odds of EBF practice. Conclusion: Age of index child, marriage type, maternal education, marital status and nature of delivery independently predicted EBF practice.

Assessment of satisfaction with delivery care among mothers in selected health care facilities in Ekiti state.

The study assessed the maternal satisfaction with delivery care in selected health care facilities in Ekiti state. The study employed a descriptive cross-sectional study design and a simple random sampling technique was utilized to select respondents based on calculated sample size and a total of 267 respondents participated in the study. A semi-structured pretested questionnaire was used for the data collection. Data was analyzed and summarized using descriptive statistics and inferential statistics (Chi-square) with significance set at p < 0.05. The mean respondents' age was 28.2 ± 1.4 years with majority falling within the age group of 21-30 years. Majority of the respondents revealed to be satisfied with the following: proximity of the health facilities 194 (72.7%); cost of service 174 (65.2%); drug availability 184 (69.7%); cleanliness of the hospital ambience 219 (82.0%); and professional conduct of the care givers 186 (70.2%). However, the respondents expressed dissatisfaction in terms of the following: referral link 107 (40.1%); waiting time 122 (45.7%); communication gap 56 (21.0%); and maintenance of privacy 51 (19.1%). Overall, majority (94.8%) of the respondents were satisfied with the delivery services rendered at the facilities while 14 (5.2%) expressed dissatisfaction. Furthermore, a significant association exists between respondents' level of education and maternal satisfaction on delivery care (p < 0.05). Although the general maternal gratification/satisfaction on intrapartum and postpartum care in this study was overwhelmingly high, the few domains of discontentment identified need to be addressed by all the stakeholders in the health sector to enhance the usage of health care services amongst women, thus promoting the attainment of Sustainable Development Goal (SDG) 3.

A comprehensive review of biomass resources and biofuel production in Nigeria: potential and prospects.

The quest for biofuels in Nigeria, no doubt, represents a legitimate ambition. This is so because the focus on biofuel production has assumed a global dimension, and the benefits that may accrue from such effort may turn out to be enormous if the preconditions are adequately satisfied. As a member of the global community, it has become exigent for Nigeria to explore other potential means of bettering her already impoverished economy. Biomass is the major energy source in Nigeria, contributing about 78% of Nigeria's primary energy supply. In this paper, a comprehensive review of the potential of biomass resources and biofuel production in Nigeria is given. The study adopted a desk review of existing literatures on major energy crops produced in Nigeria. A brief description of the current biofuel developmental activities in the country is also given. A variety of biomass resources exist in the country in large quantities with opportunities for expansion. Biomass resources considered include agricultural crops, agricultural crop residues, forestry resources, municipal solid waste, and animal waste. However, the prospects of achieving this giant stride appear not to be feasible in Nigeria. Although the focus on biofuel production may be a worthwhile endeavor in view of Nigeria's development woes, the paper argues that because Nigeria is yet to adequately satisfy the preconditions for such program, the effort may be designed to fail after all. To avoid this, the government must address key areas of concern such as food insecurity, environmental crisis, and blatant corruption in all quarters. It is concluded that given the large availability of biomass resources in Nigeria, there is immense potential for biofuel production from these biomass resources. With the very high potential for biofuel production, the governments as well as private investors are therefore encouraged to take practical steps toward investing in agriculture for the production of energy crops and the establishment of biofuel-processing plants in Nigeria.
