Prevalence and factors associated with HIV testing among young women in Ghana.

BACKGROUND: HIV/AIDS is a global health challenge and continues to threaten lives in sub-Saharan African countries such as Ghana. One of the important interventions for controlling its transmission is through testing and receiving medication. In this study, we present findings on the prevalence and factors associated with HIV testing among young women in Ghana. METHODS: We used data from the 2014 Ghana Demographic and Health Survey comprising young women aged 15-24 years. We calculated the proportion of these young women who have ever been tested for HIV. The multivariable logistic regression analysis was used to assess the determinants of HIV testing at a 95% confidence interval (CI), and adjusted odds ratio (aORs) and p-values were reported. All analyses were adjusted using survey weights to account for unequal sampling probabilities. RESULTS: The results showed that 31.4% (95% CI [29.63, 32.81]) of young women in Ghana had tested for HIV. The odds of HIV testing were likely to be higher among young women aged 20-24 (aOR = 2.24, 95% CI [1.75, 2.87]), those who were pregnant (aOR = 3.17, 95% CI [2.03, 4.95]) and those with one (aOR = 7.99, 95% CI [5.72, 11.17]), two (aOR = 10.43, 95% CI [6.47, 16.81]) or three or more children (aOR = 14.60, 95% CI [8.37, 25.48]) compared to their counterparts in the reference category. Women who had attained secondary education or higher (aOR = 2.66, 95% CI [1.67, 4.23]), were sexually active (aOR = 2.82, 95% CI [2.00, 3.97]), and in richer (aOR = 1.98, 95% CI [1.17, 3.34]) and richest wealth index (aOR = 1.99, 95% CI [1.10, 3.61]) were more likely to test for HIV than those with no formal education, who had not had sex before or in the poorest wealth index. Women from the Eastern (aOR = 1.69, 95% CI [1.04,2.72]) and Upper East regions (aOR = 2.62, 95% CI [1.44, 4.75]) were more likely than those in the Western region to get tested for HIV. However, the odds of testing for HIV were lower among women belonging to other religions (aOR = 0.43, 95% CI [0.23,0.82]) than Christians. CONCLUSION: The findings show that HIV testing is low among young women in Ghana. To address this issue, it is recommended that both government and non-governmental organizations collaborate to create effective programmes and strategies. These may include continuous health education, regular sensitization programs and making HIV testing services much more accessible and affordable, taking into consideration the sociodemographic characteristics of young women.

Knowledge of HIV transmission during pregnancy among women of reproductive age in Ghana.

INTRODUCTION: Human immunodeficiency virus (HIV) remains a significant health challenge affecting many people including those from sub-Saharan Africa (SSA). Even though HIV can be transmitted through various means, mother-to-child transmission (MTCT) remains the major route of transmission in children under the age of five. This study examined the correlates of knowledge of HIV transmission during pregnancy among reproductive-age women in Ghana. METHODS: Data for this study were obtained from the 2014 Ghana Demographic and Health Survey. The sample consisted of 9,106 women aged 15 to 49 years. We conducted both descriptive and multivariable logistic regression analyses to determine the prevalence and factors associated with knowledge of HIV transmission during pregnancy. The results were presented using frequencies, percentages, and adjusted odds ratios (aOR) with their corresponding 95% confidence intervals (CI). RESULTS: Approximately, 69.41% of women of reproductive age knew of HIV transmission during pregnancy. Women who had two (aOR = 1.32, 95% CI [1.01, 1.72]) or three (aOR = 1.37, 95% CI [1.07, 1.76]) births were more knowledgeable of HIV transmission during pregnancy. Women who read the newspaper (aOR = 1.56, 95% CI [1.31, 1.86]), listened to the radio (aOR = 1.23, 95% CI [1.05, 1.45]), lived in rural areas (aOR = 1.30, 95% CI [1.09, 1.54]) or ever been tested for HIV (aOR = 1.20, 95% CI [1.05, 1.37]) were more likely to be knowledgeable of HIV transmission during pregnancy than their counterparts in the reference categories. Compared to those in the Western Region, women in the Upper East (aOR = 0.45, 95% CI [0.32, 0.63]), Upper West (aOR = 0.54, 95% CI [0.35, 0.85]), Ashanti (aOR = 0.75, 95% CI [0.58, 0.97]) and Greater Accra Regions (aOR = 0.74, 95% CI [0.56, 0.98]) were less knowledgeable of HIV transmission during pregnancy. CONCLUSIONS: The study highlights a gap in the knowledge of HIV transmission during pregnancy among women in Ghana. Continuous public education is required to educate women on HIV transmission from mothers to their children during pregnancy and how this may be interrupted. Such programs should involve the use of the media and take into consideration the demographic and geographic characteristics highlighted as determinants in this study. This will ultimately contribute to the reduction of MTCT of HIV in Ghana.

Self-reported continuing professional development needs of medical laboratory professionals in Ghana.

BACKGROUND: Because of the essential nature of the work of medical laboratory professionals, continuing development in knowledge and skills is indispensable. The study aimed at identifying and prioritizing the development and training needs of medical laboratory professionals in Ghana. This is expected to help in developing focused continuing professional development (CPD) that meets the needs of practitioners as well as the changing medical trends. METHODS: An online cross-sectional survey in February 2022 using a structured questionnaire was conducted. Respondents were asked questions that collected demographic and work-related data about them, their participation, preference, and challenges in being part of CPDs. Finally, a list of topics based on (i) quality management systems, (ii) technical competence, (iii) laboratory management, leadership, and coaching, (iv) pathophysiology, and (iv) data interpretation and research were asked with the option to rate them on a 3-point scale (most, moderate, and least) in order of importance. RESULTS: A total of 316 medical laboratory professionals participated in the study. Overall, the most frequently selected topics for training based on domains for CPD training and ranking as most important were (i) quality management systems, (mean = 80.59 ± 9.024; 95% CI = 73.04-88.13); (ii) pathophysiology, data interpretation, and research (mean = 78.0 ± 6.973; 95% CI = 73.97-82.03); (iii) technical competence (mean = 73.97 ± 10.65; 95% CI = 66.35-81.59); and (iv) laboratory management, leadership, and coaching (mean = 72.82 ± 9.719; 95% CI = 67.44-78.2). The factors affecting the choice of training needs included the medical laboratory professionals' current place of work, years in service, the reason for attending CPD activities, the period for attending the last CPD, being in a supervisory role, and the number of staff being supervised. Face-to-face presentations, training workshops, and hands-on workshops were the most preferred modes of CPD delivery with financial implications and workload/time constraints being the main challenges impeding CPD participation. CONCLUSION: The identified needs will help in developing CPD programs that address what medical laboratory professionals prioritize as training needs. Stakeholders should incorporate these training needs into future programs and address the challenges highlighted in this study to have more relevant training for medical laboratory professionals.

Wealth-related inequalities in the utilisation of modern contraceptives in Papua New Guinea: evidence from the 2016-2018 Demographic and Health Survey data.

OBJECTIVE: To examine the wealth-related disparities in modern contraceptives use among women in Papua New Guinea. DESIGN: We performed a cross-sectional analysis of the 2016-2018 Papua New Guinea Demographic and Health Survey data. We included 11 618 women of reproductive age in our final analysis. Percentages were used to present the results on utilisation of modern contraceptives. A concentration curve was used to summarise the cumulative use of modern contraceptives by wealth index (ranked into groups: richest, richer, middle, poorer and poorest). We used a decomposition analysis to estimate the contributions of individual factors towards wealth-related inequality in modern contraceptives use. We estimated the slope index of inequality (SII) and the relative index of inequality (RII) in modern contraceptive utilisation to provide summary evidence of inequality. SETTING: Papua New Guinea. PARTICIPANTS: Women aged 15-49 years. OUTCOME MEASURE: Modern contraceptives utilisation. RESULTS: Overall, 27.5% of Papua New Guinea women used modern contraceptives. The concentration curve showed that the use of modern contraceptives was highly concentrated among women of the richest household wealth index as the concentration curve lies below the equality line. The SII (0.210, CI 0.182 to 0.239) indicates that the richest group uses more modern contraceptives. The RII depicts a relative difference of 2.044 between the richest and the poorest women in the use of modern contraceptives. CONCLUSIONS: Our study has shown that modern contraceptives use among women in Papua New Guinea is low. Women from the richest household wealth index group had the highest propensity to use modern contraceptives in comparison with those from poorer homes. The Ministry of Health and other organisations must design and carry out initiatives aimed at enhancing the availability of and use of modern contraceptives among women from less affluent backgrounds.

Health-related quality of life of type 2 diabetes mellitus patients: A cross-sectional study in the cape coast metropolis.

Background and Aim: Type 2 diabetes mellitus (DM) has in recent decades become a global pandemic, accounting for over 90% of DM cases. The study evaluated the health-related quality of life (HrQoL) and identified its determinants among type 2 DM patients at the University of Cape Coast Hospital. Methods: We conducted our study at the University of Cape Coast Hospital from January to March 2022. The EQ-5D-5L questionnaire was administered to 68 type 2 DM patients. Data were then inputted into Microsoft Excel and analyzed accordingly using IBM SPSS statistical software version 26 and GraphPad Prism 8. Results: The mean age of the participants was 60.71 ± 12.18 with 55.9% being females. The average systolic, diastolic blood pressure and fasting blood glucose (FBG) of participants were 140.99 ± 22.27, 85 ± 11.14 and 7.97 ± 2.66 respectively. With the EQ-5D-5L scale, participants reported severe to extreme problems mainly in pain/discomfort (19.1%) and mobility (8.8%) dimensions. Approximately 21% (14/68) of patients reported themselves as being in perfect health based on the EQ-5D index score with no significant difference between males and females (p ≥ 0.05). On a scale of 0 to 100, most (26.5%) of the participants rated their general health state at 80. Age was significantly associated with all five dimensions while patients with comorbidities had higher odds of experiencing pain/discomfort and anxiety/depression. Conclusion: The study reveals that pain/discomfort and anxiety/depression are the most experienced problems among patients with type 2 DM. The HrQoL of type 2 DM patients was also found to be affected by age, comorbidities, systolic and diastolic blood pressure. Therefore, identifying these factors and developing appropriate interventions is crucial for improving patient outcomes and enhancing treatment outcomes.

Hygienic Disposal of Children's Stools Practices Among Women of Children With Diarrhoea in Sub-Saharan Africa.

Background: Diarrhoea stools contain infectious agents and pose a public health threat to children and members of the entire family when exposed to them. Therefore, their hygienic disposal is essential. Empirical data are needed to stir the needed public health interventions to encourage or enforce proper disposal practices to curb associated clinical issues. This study assessed the prevalence and correlates of hygienic stool disposal practices by mothers of children with diarrhoea in sub-Saharan Africa (SSA). Methods: The Demographic and Health Surveys (DHS) data of 16 sub-Saharan African countries from 2015 to 2021 involving 22 590 mother-child pairs were analysed. Multilevel binary logistic analysis was conducted to assess the individual- and household-level factors associated with the hygienic disposal of stool practices by mothers of children with diarrhoea. The results were presented using adjusted odds ratios (AOR) and 95% confidence intervals (CI) at a statistical significance of P < .05. Results: The overall prevalence of hygienic disposal of children's stools among women of children with diarrhoea was 49.01% (95% CI: 48.40-49.62) and ranged from 15.70% in Liberia to 86.6% in Rwanda. The practice of hygienic disposal of stools of children with diarrhoea was likely to increase among mothers who are working (AOR: 1.19; 95% CI: 1.09-1.30), those with partners with primary level of education (AOR: 1.18; 95% CI: 1.06-1.31), Muslims (AOR: 1.69; 95% CI: 1.49-1.91) and widowed/divorced (AOR: 8.94, 95% CI: 3.55-22.53). Again, mothers in the richer (AOR: 1.23; 95% CI: 1.08-1.39) wealth index had increased odds of disposing of stools hygienically compared to those in the poorest wealth index. Women who were 20 years and above, to who belonged to Traditional Religions (AOR: 0.57; 95% CI: 0.43-0.74), and those with unimproved sources of water (AOR: 0.89; 95% CI: 0.82-0.98) and toilet facilities (AOR: 0.63; 95% CI: 0.58-0.69) were less likely to dispose of child's diarrhoea stool hygienically than their counterparts. Conclusion: The study reveals that the unhygienic disposal of the stool of children with diarrhoea is prevalent in SSA and requires a concerted effort to curb it. Sanitation practices such as educating mothers about hygienic disposal of children's stool and improving water and sanitation facilities are crucial in lowering the high prevalence of unhygienic disposal of the diarrhoeic stool of children. Additional country-level research is needed to assess children's defecation behaviours and the disposal of diarrhoeic stools using different methodologies.

Urinogenital schistosomiasis knowledge, attitude, practices, and its clinical correlates among communities along water bodies in the Kwahu Afram Plains North District, Ghana.

BACKGROUND: Adequate knowledge and proper practices coupled with knowledge of the burden of disease are necessary for the eradication of Schistosoma infection. This study assessed knowledge, attitude, and practice (KAP) as well as health outcomes related to Schistosoma haematobium infection at Kwahu Afram Plains North District (KAPND). METHODS: A cross-sectional survey using a structured questionnaire was carried out among 140 participants from four local communities in KAPND in August 2021. From these participants, 10ml of urine was collected for determination of the presence of S. haematobium and urine routine examination. In addition, 4ml of blood was collected and used for haematological examination. Descriptive statistics and logistic regression analysis using IBM SPSS were used to describe and represent the data collected. RESULTS: The study reports a gap in knowledge about schistosomiasis in the study area with the majority indicating that they have not heard of schistosomiasis (60.7%), do not know the mode of transmission (49.3%), and do not know how the disease could be spread (51.5%). The overall prevalence of urinary schistosomiasis was 52.9%. This was associated with age, occupation, perceived mode of Schistosoma transmission, knowledge of Schistosoma prevention, awareness that schistosomiasis can be treated, frequency of visits to water bodies, and water usage patterns. In multivariate analysis, factors that remained significantly associated with S. haematobium infection were age 21-40 (OR = 0.21, 95% CI: 0.06-0.76), 41-60 (OR = 0.01, 95% CI: 0.01-0.52) and ≥ 60 (OR = 0.02, 95% CI: 0.02-0.87), informal employment (OR = 0.01, 95% CI: 0.01-0.69) and awareness of transmission by drinking water from river body (OR = 0.03, 95% CI: 0.03-0.92). In Schistosoma infection, reduced haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, lymphocytes and eosinophils were observed. White blood cells, neutrophils, and monocytes were significantly elevated in infected states. Urine analysis revealed high pus cells and red blood cells counts among Schistosoma-positive participants. CONCLUSION: Schistosoma infection is endemic among inhabitants in KAPND, and is associated with a gap in knowledge, awareness, and practice possibly due to inadequate education in the area. Poor clinical outcomes associated with Schistosoma infection have been demonstrated in the area. A well-structured public education, nutritional intervention, and mass drug administration will be necessary to eradicate this menace.

Willingness to receive COVID-19 booster dose and its associated factors in Ghana: A cross-sectional study.

Background and Aim: The COVID-19 booster dose has been cited as an important supplement for the control of the COVID-19 pandemic due to reports of waning immunity among fully vaccinated persons. Determining factors that would affect its acceptability is necessary for initiating successful vaccination programs. In this study, we aimed to evaluate the factors associated with the acceptability of the COVID-19 booster dose in Ghana. Methods: We conducted an online cross-sectional survey among the public. A self-administered questionnaire was used to collect information on demographic characteristics, willingness to vaccinate, perceptions toward COVID-19 vaccines, and trust in the government. Participants provided reasons and sources of advice that may affect their willingness to accept a booster dose. Using IBM SPSS and R Statistic; descriptive, univariate, and multivariate analyses were performed. Results: Out of 812 respondents, 375 (46.2%) intended to accept the booster dose. Individuals who were males (adjusted odds ratio [aOR] 1.63, 95% confidence interval [CI] 1.07-2.48), had previously received other forms of vaccination twice (aOR 1.96, 95% CI 1.07-3.57) or in most years (aOR 2.51, 95% CI 1.38-4.57), tested positive for COVID-19 (aOR 3.46, 95% CI 1.23-10.52), have high trust in government (aOR=1.77, 95% CI: 1.15-2.74) and had positive perceptions regarding COVID-19 vaccines (OR = 14.24, 95% CI: 9.28-22.44) were more likely to accept a booster dose. Experiencing side effects from the primer dose (aOR 0.12, 95% CI 0.08-0.18) was associated with reduced acceptance. Concerns about vaccine safety and efficacy were the common reasons impeding willingness, while advice from health professionals would be the most considered. Conclusion: Low intention to accept the booster dose which is associated with a range of factors including the perception of vaccines and trust in the government, is a cause for concern. Thus, more effort would have to be taken through education and policy interventions to increase booster vaccine acceptability.

Cervical Microbiota Influences Cytokine Diversity in Cervical Intraepithelial Neoplasia among Rural Women in the Akyemansa District of Ghana.

Background: In recent times, cervical dysbiosis which mostly causes and aggravates infections is highlighted for its role in immune modulation in cervical dysplasia, which promotes the shifting of Th1 phenotype immunity to Th2 phenotype immunity. This study therefore estimated and compared the levels of circulatory IL-4, IL-6, IL-10, TNF-α, and IFN-γ cytokines among adult women identified to have different grades of cervical intraepithelial neoplasia (CIN) and with cervicovaginal infection. Methods: A total of 157 participants were recruited from the Akyemansa District of Ghana, and cervical swabs and blood samples were taken. The Pap smear test, microbiological culture, and ELISA were employed for cytology analysis, bacteria isolation, and identification and estimation of IL-4, IL-6, IL-10, TNF-α, and IFN-γ cytokines, respectively. Results: Overall, 14/157 (8.9%) had CIN with 7.6% having CIN 1 and 1.3% having CIN 2. The main predictor for CIN was age above 46 years (OR 11.16, 95% CI: 2.4-51.8). Bacterial vaginosis (p = 0.003) and Candida infection (p = 0.012) were significantly higher in CIN. Again, Staphylococcus aureus (60% vs. 17.6%, p = 0.005), Citrobacter sp. (40.0% vs. 13.2%, p = 0.017), and Morganella morganii (40.0% vs. 4.4%, p = 0.002) isolates were significantly higher in CIN-positive participants. IL-10 and TNF-α concentrations were elevated in participants with CIN 1+ (TNF-α NIL vs. CIN 1+ only, p < 0.05) while IL-6 was decreased among participants with CIN 1+. In the presence of vaginal infection, TNF-α decreased among CIN 1+ participants while IL-10 remained elevated. Conclusion: The findings of this study suggest that cervical dysbiosis causes immune suppression, which creates a suitable microenvironment for the development of CIN.

Toward schistosomiasis control: Assessment of infection-associated voiding symptoms, quality of life and the impact of exercise coupled with water intake on egg recovery in an endemic community in Ghana.

Assessment of the burden of disease and techniques for clinical diagnosis could ultimately help in schistosomiasis control. This study assessed the impact of exercises and water intake on ova recovery during laboratory diagnosis and schistosomiasis-associated urinary symptoms and quality of life (QOL) among inhabitants of Dendo, an endemic community in Ghana. The clinical findings and responses of 400 randomly selected participants were used for the study. The International Prostate Symptoms Score (I-PSS) was used to collect information on participants' self-reported urinary symptoms and QOL. Finally, urine samples were collected on two consecutive days, initially without exercise and water intake and then after exercise and water intake, and about 10 ml of it were microscopically examined for the presence and quantification of ova. The data collected from the study were analyzed using IBM SPSS. Schistosoma haematobium egg recovery increased significantly (p < 0.001) from 206 (51.5%) to 220 (55.0%) after exercise and water intake with the highest increase being observed among participants less than 20 years (53.3% to 57.1% after exercise and water intake). As high as 90.3% and 56.8% of Schistosoma-positive participants reported IPSS>7 (symptomatic voiding disorders) and QOL≥4 (mostly dissatisfied or unhappy QOL) respectively. The commonest voiding symptoms reported were nocturia (98.9%) and incomplete emptying (79.6%). Positive correlations between egg count, IPSS score, and QOL were observed. This study provides important evidence for the inclusion of exercise and water intake in the microscopic diagnosis of Schistosoma haematobium and reveals that schistosomiasis significantly impacts the affected individuals' urinary health and overall quality of life.

Enteric Protozoan Parasitosis and Associated Factors among Patients with and without Diabetes Mellitus in a Teaching Hospital in Ghana.

Background: Enteric protozoa infections (EPIs) could worsen clinical outcomes in patients with diabetes mellitus and therefore requires prompt and accurate diagnosis and attention. This study aimed to determine the burden of EPIs and their associated factors among patients with and without diabetics at the Komfo Anokye Teaching Hospital (KATH) in Ghana. Again, the diagnostic performance of parasitological techniques routinely used for diagnosis was assessed. Methods: A total of 240 participants (made up of 140 patients with diabetes and 100 patients without diabetes) were recruited into the study by simple random sampling from November 2020 to May 2021. Stool samples of participants were collected, along with their demographic information, and examined using the saline direct wet mount (DWM), formol-ether concentration (FEC), and modified Ziehl-Neelsen staining (ZNS) techniques for the presence of enteric protozoans. Results: Enteric protozoa were found among 62/140 (44.3%) diabetic patients and 13/100 (13.0%) nondiabetic patients. The predominant protozoa identified were Cryptosporidium spp. (17.86%) among patients with diabetes and Blastocystis hominis (7.0%) among patients without diabetes. EPI was associated with diabetes mellitus status (AOR = 3.48, 95% CI, 1.55-7.79), having diabetes for more than five years (AOR = 3.83, 95% CI, 1.65-8.86) and having comorbidity (AOR = 2.93, 95% CI, 1.33-6.45). The FEC technique had the highest sensitivity (100.0%), specificity 94.3% (95% CI, 91.35-97.22), and accuracy 95.0% (95% CI, 88.54-98.13) when compared to other techniques for diagnosis. Conclusion: EPIs are a significant health problem among patients with diabetes at KATH, and therefore antiparasitic drugs should be included in their treatment protocols for better health outcomes. Again, the FEC technique has demonstrated better performance in detecting EPIs and is therefore recommended to achieve early and accurate diagnosis of EPIs.

Adverse drug effects among students following mass de-worming exercise involving administration of Praziquantel and Albendazole in KEEA Municipality, Ghana.

BACKGROUND: To manage the deleterious effects of parasitic infections such as lymphatic filariasis (LF) and schistosomiasis among school children, most countries including Ghana make use of mass drug administration (MDA). Although MDA has proven effective in reducing worm burden, unfortunately adverse drug effects (ADEs) post-MDA are derailing the gains and also remain poorly monitored. The study assessed incidence and factors associated with ADEs among students following a school-based mass de-worming exercise involving administration of Praziquantel (PZQT) and Albendazole (ADZ) against LF and SCH at Komenda-Edina-Eguafo-Abirem (KEEA) Municipal. METHODOLOGY: After fulfilling all ethical obligations, a total of 598 students aged 5-20 years who received PZQT or ADZ monotherapy or a combination of the two (PZQT + ADZ) as part of the mass de-worming exercise were recruited through quota and random sampling. Bodyweight and height of students were measured and body mass index (BMI) calculated. Students were orally interviewed to obtain information such as age, sex, intake of diet before taking drugs. Subsequently, students were monitored over 24 hours post-MDA for cases of ADEs. Descriptive statistics and logistic regression analysis using SPSS version 26 was used to describe data collected and to determine associations between incidence of ADEs and predictor variables. PRINCIPAL FINDINGS: Out of the 598 students, 243 (40.64%) represented by 124 males (51.03%) and 119 females (48.97%) with mean (SD) age of 13.43 (2.74) years experienced one or more forms of ADE. In decreasing order, the detected ADEs included headache (64.6%), Abdominal pain (48.6%), fever (30.0%), diarrhea (21.4%) and itching (12.8%). Multivariable statistical analysis showed that age 5-9 years (OR: 2.01, p = 0.041) and underweight (OR: 2.02, p = 0.038) were associated with incidence of ADEs. Compared with students who received combination therapy, students who received ADZ only (OR: 0.05, p < 0.001) and PZQT only (OR: 0.26, p < 0.001) had low cases of ADEs. Gender and diet intake before MDA were not associated with ADE incidence. CONCLUSION: ADE incidence was common among students in the KEEA municipality. Age, underweight, and double dosing were associated with increase in ADE incidence, while gender and food intake were not associated with increase in ADE incidence. The Disease Control Unit of the Ghana Health Service should incorporate stringent ADE monitoring in post-MDA surveillance in the National MDA program in order to be able to detect, manage and report ADEs to inform planning for future MDA programs. Such initiatives will help not only in improving effectiveness of MDA programs but also identify high risk groups and exact strategies to reduce negative influence of ADE on MDA coverage and anthelminthic drug compliance.

Wound Healing Properties and Antimicrobial Effects of Parkia clappertoniana Keay Fruit Husk Extract in a Rat Excisional Wound Model.

Background: Parkia clappertoniana Keay (Family: Fabaceae) (P. clappertoniana) fruit husk is commonly used in northern Ghana for wound treatment. However, this folk claim remains to be confirmed scientifically. Objective: This study investigated wound healing and antimicrobial effects of P. clappertoniana fruit husk extract (PCFHE) by using excision wound model in rats. Materials and Methods: After preparation and phytochemical analysis of PCFHE, it was reconstituted in purified water and emulsifying ointment yielding a wound healing formula (0.3, 1, and 3%). Excision wounds were established in healthy male Sprague-Dawley rats (aged 8-10 weeks; weighing 150-200 g). Rats were randomly assigned into six groups (model, 1% silver sulfadiazine [SSD], vehicle, and PCFHE [0.3, 1, and 3%, respectively]) and topically treated daily until complete wound healing. The endpoints (period of epithelialization, wound contraction, collagen content, erythema index, oedema index, inflammatory cell infiltration, and antimicrobial activity) were assessed for all groups. Minimum fungicidal concentration (MFC), minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and time-kill were assessed. Results: Quercetin and catechin were detected in PCFHE. Compared to model and vehicle groups, PCFHE-treatment groups improved wound healing and antimicrobial (MBC, MFC, and MIC) endpoints. PCFHE demonstrated bacteriostatic and fungicidal effects against identified wound contaminants (Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and Candida albicans). Conclusion: P. clappertoniana fruit husk possesses wound healing and antimicrobial effects in excisional wounds in rats that confirms its folk use, and the reported pharmacological properties of PCFHE are attributable to its quercetin and catechin phyto-constituents.

Zanthoxylum zanthoxyloides Alkaloidal Extract Improves CCl4-Induced Hepatocellular Carcinoma-Like Phenotypes in Rats.

BACKGROUND: Despite the enrollment of new small molecules such as Sorafenib for the treatment of hepatocellular carcinoma (HCC), HCC still remains a significant contributor to cancer-related mortality and morbidity globally. Zanthoxylum zanthoxyloides is long suspected of possessing anticancer bioactive compounds that may hold the prospect of adjunctive therapy against inflammation-related cancers such as HCC. OBJECTIVE: This study assessed the effects of an alkaloidal extract of the leaves of Zanthoxylum zanthoxyloides on CCl4/olive oil (1 : 1 v/v)-induced HCC-like phenotypes in rats. MATERIALS AND METHODS: Zanthoxylum zanthoxyloides alkaloidal extract (ZZAE) was prepared using Soxhlet and liquid-liquid extraction methods. Subsequently, ZZAE was characterized phytochemically. In the curative method, experimental HCC was established in adult (8-10 weeks old) male Sprague-Dawley rats weighing 150-300 g by twice-daily administration of CCl4/olive oil (1 : 1 v/v) (2 mL/kg ip). After confirmation of experimental HCC in rats, the rats were randomly reassigned into seven (7) groups of seven (7) rats each and treated daily for 12 weeks as follows: control (normal saline, 5 ml/kg po), model (CCl4, 5 ml/kg, ip), ZZAE (50, 100, and 200 mg/kg po), carvedilol (6.25 mg/kg po), and 20% Tween20 (1 mL/rat, po). To assess whether ZZAE has a prophylactic (preventive) effect, rats were first treated with ZZAE and later exposed to CCl4 reconstituted in olive oil. RESULTS: ZZAE (100 and 200 mg/kg) and carvedilol decreased tumor incidence compared to that of control. Compared to control, ZZAE (100 and 200 mg/kg) significantly (P < 0.05) improved serum GGT. Compared to control, ZZAE improved hepatohistological distortions induced by CCl4/olive oil and also improved liver/body weight ratio. Compared to water, ZZAE arrested mitosis in the Allium cepa assay. CONCLUSION: ZZAE ameliorated CCl4/olive oil-induced HCC-like phenotype in rats and demonstrated general hepatoprotective effects by improving liver and kidney function markers. This finding rationalizes the need for further studies on ZZAE as a potential source of bioactive anti-HCC compounds.
