Although treatments through statins have recorded exponential success over time, regrettably, several patients have yet to attain the minimum levels of low-density lipoprotein-cholesterol (LDL-Ch), evidenced by the high cardiovascular outcomes after treatment. Hence, this research aimed at evaluating the effect of <em>Waltheria indica</em> leaf diets on the lipid profiles and antioxidant activities in male albino rats weighing 40-45 g, which were grouped into three: Group A (basal group without cholesterol), Group B control (diet + 1% cholesterol) and Group C test diet (1% cholesterol + 10% <em>Waltheria indica</em> leaf sample) and fed for 21 days and weighed before sacrifice. After the last day of feeding, the Serum and liver were excised, and lipid profile and antioxidant enzyme activities were analyzed using standard methods. Serum total cholesterol (mg/dl) decreased significantly (p&lt;0.05) from 83.88 ± 2.74 in control rats (group B) to 23.14 ± 1.05 in group C rats. Also, serum high-density lipoprotein (mg/dl) increased significantly (p&lt;0.05) from 17.09 ± 0.71 in control rats to 33.25 ± 4.01 in group C rats. The serum malondialdehyde level decreased markedly from 8.68 ± 0.07 in group B rats to 5.74 ± 0.40 in group C rats. The activity of Serum Catalase significantly increased from 2.29 ± 0.15 in group B rats to 3.75 ± 0.13 in group C rats. This study demonstrates the lipid-lowering potential of <em>Waltheria indica</em> leaf diets and its protective effects against oxidative stress, which holds promise in managing and treating hypercholesterolemia.</p> Tobiloba Bajepade, Olumide Fashakin, Folake Oyetayo Copyright (c) 2024 Covenant Journal of Physical and Life Sciences https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4292 Tue, 05 Nov 2024 00:00:00 +0000 MICROBIAL CONTAMINATION AND ANTIBIOTIC RESISTANCE IN SELECTED YOGHURT BRANDS IN ELELE, RIVERS STATE, NIGERIA https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4521 <p>Yogurt, a widely consumed fermented dairy product, offers numerous nutritional benefits but is susceptible to microbial contamination, posing potential public health risks. This study evaluates the microbial contamination in twelve brands of yogurt sold in Elele, Rivers State, Nigeria, analyzing ambient and frozen samples. The results revealed higher bacterial loads in yogurt stored at room temperature, with <em>Bacillus sp </em>(40%) being the most prevalent contaminant, followed by <em>Lactobacillus bulgaricus</em> (30%) and <em>Salmonella sp</em> (35%)., the latter of which is particularly concerning due to its potential to cause foodborne illnesses. Additionally, antibiotic susceptibility testing demonstrated that the isolated bacteria exhibited significant multi-drug resistance, especially <em>Salmonella sp</em>., which was resistant to eight of ten antibiotics tested. These findings highlight the importance of proper storage conditions, strict hygiene practices, and the need for enhanced safety measures during yogurt production to minimize health risks associated with contaminated yogurt products.</p> Martin ANAGBOSO, Chioma Ohaebuka, Edith Mbah, Oluchi Osuala, Chidinma DAOKORU-OLUKOLE, Ebisomu AGEDAH, Euslar Onu, Grace Nwankwo, Freda Okafor, Iheanyi Okonko Copyright (c) 2024 Covenant Journal of Physical and Life Sciences https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4521 Thu, 17 Oct 2024 00:00:00 +0000 Patients’ Satisfaction with waiting time and healthcare givers’ attitude: outcome of patient’s compliance to treatment at the University of Benin Teaching Hospital and Central Hospital, Benin City Edo State, Nigeria https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4523 <p>The growing concern about the importance of patient satisfaction as an essential tool in assessing the quality of care is a recent trend in the health sector in Nigeria. This study underscores the urgent need for a shift towards patient-centred care, a model that has proven successful in developed countries. The same cannot be said of developing countries like Nigeria and Ghana. This study evaluated patients' satisfaction with service delivery in tertiary and secondary health institutions in South-South Nigeria. It was a quantitative and qualitative study on 200 inpatients and outpatients at the University of Benin Teaching Hospital (UBTH) and Central Hospital, both located in Benin City, Edo state, Nigeria Data were collected using a pretested structured questionnaire, Focus Group Discussion, and Non-participant Observation. Data from the quantitative study were analysed using the statistical package for Social Science (SPSS) version (20) in the form of frequencies, percentages and chi-square to determine the association among variables. Reports of Focus Group Discussions and Observations were written in summary paragraphs. Findings revealed that patients' dissatisfaction with waiting times and workers’ attitudes did not deter them from complying with the treatment process; they continued using health units and recommended health units to others. Patients’ satisfaction with waiting time and staff patients’ relationships were poor. These, though, do not affect patients’ compliance with the treatment process, continued utilisation of health units and recommendation of health units to others.</p> Rita Okoebor Copyright (c) 2024 Covenant Journal of Physical and Life Sciences https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4523 Wed, 16 Oct 2024 00:00:00 +0000 PREVALENCE AND CO-INFECTION OF HELICOBACTER PYLORI AND HEPATITIS C VIRUS AMONG HIV PATIENTS ON ART IN PORT HARCOURT, NIGERIA https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4607 <p><strong><em>Helicobacter pylori</em></strong><strong> is one of the most common and medically prominent infections worldwide and has been implicated in various gastric disorders including peptic ulcer disease (PUD). Several investigators have reported a high prevalence of <em>H. pylori</em> infection in patients with chronic liver diseases. Some have suggested that it might contribute to the mechanism of hepatitis C (HCV) related hepatocellular carcinoma (HCC). The relationship between <em>H. pylori</em> and chronic hepatitis C (CHC) remains controversial. This cross-sectional study aimed to investigate the seroprevalence of <em>H. pylori</em> co-infection with Hepatitis C among HIV-positive patients receiving antiretroviral therapy (ART) and its correlation with viral load at the Rivers State University Teaching Hospital (RSUTH), Nigeria. A total of two hundred (200) participants were recruited and screened for <em>Helicobacter pylori</em> and HCV antibodies using rapid diagnostic tests (RDTs) while HIV viral load was performed using Reverse Transcription-polymerase chain reaction (RT-PCR), Questionnaires were used to obtain demographic data of the participant. The results revealed a 60.5% prevalence of <em>H. pylori</em>, with none testing positive for antibodies to HCV (Anti-HCV). The majority of the participants were within the age range of 33-40 years, predominantly females 69.0%, married 46.0%, secondary education 54.0%, and participants with viral load less than 20 copies/ml 74%. Across all viral load ranges, the prevalence of the specific outcome appears to be relatively consistent, ranging from 60.1% to 63.3%. There was no statistical association between the demographic variable and the infection (p &gt; 0.05). In conclusion, while the prevalence of <em>H. pylori</em> is high with no HCV infections among HIV-infected individuals in Port Harcourt, the specific outcome or characteristic of viral load is somewhat consistent, indicating despite the difference in counts, the prevalence within each range is quite similar.</strong></p> Professor Iheanyi Omezuruike Okonko, ONORIODE DIAMEREYAN, Professor Nnenna Frank-Peterside Copyright (c) 2024 Covenant Journal of Physical and Life Sciences https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4607 Fri, 15 Nov 2024 00:00:00 +0000 SEROLOGICAL EVIDENCE OF HBc IgM AMONG HIV-INFECTED INDIVIDUALS ATTENDING SELECTED HOSPITALS IN ANAMBRA STATE, NIGERIA https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4683 <p style="text-align: justify;">The South-Eastern area of Nigeria does not currently have data on the serological evidence of anti-HBc-IgM antibodies. The study aimed to show the serological evidence of anti-HBc-IgM antibody biomarkers among HIV-infected individuals in selected hospitals in Anambra State, Nigeria. This study also investigates the prevalence of Hepatitis B core IgM (HBc IgM) among HIV-infected individuals in Anambra State, Nigeria, highlighting its sociodemographic correlates, CD4 counts, and viral load implications. Following the manufacturer's standard operating procedures, 372 participants were tested for anti-HBc IgM antibodies during a cross-sectional study. Of the 372 participants, 27.7% tested positive for HBc IgM. The overall prevalence of anti-HBc IgM antibodies (27.7%). The serological evidence of anti-HBc- IgM antibody was higher among females (32.1%), older age groups (33.8%), other marital categories (41.7%), monogamous family type (29.7%), primary educational level (41.5%), unemployed (38.5%), Christian religion (30.8%), and having HIV-positive spouse (31.7%). Among the immunological markers, a higher prevalence of anti-HBc IgM antibodies occurred in participants with CD4 counts <u>&lt;</u>200 cells/µl (52.5%). For the virological markers, a higher prevalence of anti-HBc IgM antibodies occurred among participants with a plasma viral load of <u>&gt;</u>1000 copies/ml (61.3%). This study identifies a possible danger of HBV transmission from HIV-infected individuals to the general population. Anti-HBc-IgM antibodies are prevalent in Anambra State, Nigeria and this represents the first evaluation of anti-HBc IgM in the South-Eastern region of the nation. The findings underscore the need for integrated healthcare approaches, emphasising comprehensive screening and tailored interventions to manage co-infections effectively.</p> Edith Nnenna Oketah, Chineze Helen Ugwu, Nnenna Frank-Peterside, Iheanyi Okonko Copyright (c) 2024 Covenant Journal of Physical and Life Sciences https://journals.covenantuniversity.edu.ng/index.php/cjpls/article/view/4683 Wed, 20 Nov 2024 00:00:00 +0000
