Dietary supplementation of Capsicum powder affects the growth, immunoglobulins, pro-inflammatory cytokines, adipokines, meat, and liver histology of aflatoxin B1 exposed broiler chickens.

The effects of dietary supplementation with Capsicum annuum fruit pericarp powder (CPP) and Capsicum annuum fruit seed powder (CSP) on the health and performance of broiler chickens exposed to aflatoxin B1 (AFB1) was investigated. Four dietary groups were established: CON (control), AFT (0.5 mg/kg AFB1), CPAF (0.5 g/kg CPP and 0.5 mg/kg AFB1), and CSAF (0.5 g/kg CSP and 0.5 mg/kg AFB1). The AFT group shows a significant (P < 0.05) reduction in the relative growth rate compared to CON, CPAF, and CSAF. In contrast, the latter two groups exhibit growth rates similar (P > 0.05) to CON. Additionally, immunoglobulin levels (IgG, IgM, and IgA) in the AFT group are significantly (P < 0.05) lower compared to the other treatment groups. Serum interleukin-6 levels in the CPAF and CSAF groups were similar (P > 0.05) to CON but higher (P < 0.05) than in AFT. Tumor necrosis factor-alpha levels were elevated (P < 0.05) in AFT compared to the other treatment groups. Interferon-gamma concentrations in AFT were significantly (P < 0.05) lower than in the other treatment groups. The liver histology reveals that the AFT treatment group has periportal hepatic inflammation. In contrast, the CPAF and CSAF treatment groups exhibit normal hepatic microanatomy. In conclusion, 0.5 g/kg CPAF dietary supplementation may help to ameliorate the adverse effects of AFB1 exposure on broiler chicken health, specifically the growth, immune parameters and liver histology.

National and state-level trends in the availability of mental health treatment services tailored to individuals ordered to treatment by a court: United States, 2016, 2018, and 2020.

PURPOSE: We sought to identify trends and characteristics associated with the availability of tailored mental health services for individuals involved in the criminal justice system and ordered to treatment by a court, nationally in the US and by state. METHODS: We used National Mental Health Services Survey to identify outpatient mental health treatment facilities in the US (2016 n = 4744; 2018 n = 4626; 2020 n = 4869). We used clustered multiple logistic regression to identify changes over time as well as facility- and state-level factors associated with the availability of specialty court-ordered services. RESULTS: Slightly more than half of the outpatient mental health treatment facilities offered specialized services for individuals ordered to treatment by a court, with wide variation between states. Nationally, there was a significant increase in the odds of offering court-ordered treatment in 2020 compared to 2016 (aOR = 1.16, 95% CI = 1.06-1.27, p < 0.01). Notable associations included offering integrated substance use treatment (versus none, aOR = 2.95, 95% CI = 2.70-3.22, p < 0.0001) and offering trauma therapy (versus none, aOR = 2.05, 95% CI = 1.85-2.27, p < 0.0001). CONCLUSION: The availability of mental health services for individuals ordered to treatment by a court is growing nationally but several states are lagging behind. Court ordered treatment is a promising strategy to improve health and reduce reliance on the carceral system as a healthcare provider. At the same time, we express caution around disparities within behavioral health courts and advocate for equity in access to incarceration alternatives.

Comprehensive and Integrated Services in Specialty Mental Health Treatment Facilities in the US: Differences by the Racial/Ethnic Composition of the Facility's Clientele, 2020.

The integration of multiple ancillary services into mental health treatment settings may improve outcomes, but there are no national studies addressing whether comprehensive services are distributed equitably. We investigated whether the availability of a wide range of service types differs based on the facility's racial/ethnic composition. We used the 2020 National Mental Health Services Survey to identify twelve services offered in outpatient mental health treatment facilities (N = 1,074 facilities). We used logistic regression to model each of the twelve services, predicted by the percentage of a facility's clientele that was White, Black, and Hispanic, adjusted for covariates. Facilities with the highest proportions of Black and Hispanic clientele demonstrated the lowest predicted probabilities of offering comprehensive and integrated services. Our findings offer context around upstream factors that may, in part, drive treatment disparities. We orient our findings around frameworks of structural racism and inequities in mental healthcare.

Morbidity pattern of underfives with moderate acute malnutrition in southern Nigeria

Background:Moderate acute malnutrition (MAM) is a leading cause of childhood morbidity and mortality globally. The morbidity pattern of underfives with this condition is yet to be described. Objective: To describe the morbidity pattern of underfives with MAM.Method: Across sectional study was conducted in two Primary Health Centres in Uruan Local Government Area of Akwa Ibom State. Caregivers'brought children aged 6- 59 months to the health facilities following community mobilization. Eligible children were recruited into the study after obtaining parental consent. Avalidated proforma was used to obtain the biodata and symptoms of common illnesses in the children. Ageneral physical examination, anthropometric measurements and systemic examination were performed. Results: Atotal of 162 children were recruited into the study. Their mean (±SD) age was 20.4 ± 13.0 months. Over 70% of them were 6 - 23 months of age. Their mean (±SD) length/height was 77.3 ± 29.6 cm, mean (±SD) weight was 8.3 ± 3.4 kg and mean (±SD) mid upper arm circumference was 12.4 ± 4.5 cm. The main symptoms noted in the children were; fever 99 (61.1%), cough 84 (51.9%), weight loss 81 (50.0%), diarrhoea 40 (24.7%) and vomiting 40 (24.7%) while pallor 77 (47.5%), lymphadenopathy 56 (34.6%), hair changes 49 (30.2%), skin changes 27 (16.6%) were the main signs in them.Conclusion: The main symptomatology of underfives with MAM were fever, cough and weight loss

Burnout Among Doctors and Nurses at The University of Uyo Teaching Hospital, South-South, Nigeria: A Comparative Study

BACKGROUND: Burnout remains a crucial occupational health challenge to healthcare professionals given its immediate and remote harmful effects. Doctors and nurses are highly susceptible to burnout due to the essence and demands of their services. The study aimed to determine and compare the prevalence of burnout among doctors and nurses working at the University of Uyo Teaching Hospital, Southern Nigeria. MATERIALS AND METHODS: A comparative, cross-sectional study of 553 doctors and nurses was conducted using a stratified random sampling technique. A pretested, self-administered MBI - Human Services Survey for Medical Personnel - MBI-HSS (MP) was used for data collection and analysis using IBM Statistical Product and Service Solutions (SPSS) software version 23. The Chi-square and Fisher's exact tests were applied with a statistical significance level set at α<0.05. RESULTS: The mean ages for doctors and nurses were 37.1 ± 5.3 and 39.0 ± 9.2 respectively (p=0.003). Burnout prevalence among doctors was 9.7% compared to 5.5% among nurses (p =0.062). Out of 553 respondents, 247 (46.7%) had high emotional exhaustion (EE), 70 (12.7%) had high depersonalization (DP), and 342 (61.9%) had low personal accomplishments (PA). Furthermore, 132 (47.3%) doctors had high EE, 43 (15.4%) had high DP and 159 (57%) had low PA. While 115 (42%) nurses had high EE, 27 (9.9%) had high DP and 183 (66.8%) had a low PA (p=0.041). Excessive workload (p=0.042) and lengthy years in a workplace position (p=0.002) were significantly associated with burnout among doctors compared to family size (p=0.045) and workplace support or community (p=0.005) among nurses. CONCLUSION: The study found burnout prevalence to be higher among doctors than nurses. Work-related factors contributed significantly to burnout development. Recreating and/or modifying workplace environments is essential to mitigating the adverse effects of burnout among healthcare workers.

CONTEXTE: Le burnout demeure un défi crucial pour la santé au travail des professionnels de la santé compte tenu de ses effets immédiats et à distance. Les médecins et les infirmières sont hautement susceptibles au burnout en raison de la nature et des exigences de leurs services. L'étude visait à établir et à comparer la prévalence du burnout parmi les médecins et les infirmières travaillant à l'Hôpital Universitaire de Uyo, dans le sud du Nigéria. MATÉRIEL ET MÉTHODES: Une étude comparative et transversale a été menée auprès de 553 médecins et infirmières à l'aide d'une technique d'échantillonnage aléatoire stratifié. Une enquête préalablement testée, auto-administrée, l'Inventaire d'épuisement professionnel humain pour le personnel médical (MBI-HSS [MP]), a été utilisée pour la collecte et l'analyse des données à l'aide du logiciel IBM Statistical Product and Service Solutions (SPSS) version 23. Les tests du Chi carré et de Fisher ont été appliqués avec un seuil de signification statistique fixé à α<0,05. RÉSULTATS: Les âges moyens des médecins et des infirmières étaient de 37,1 ± 5,3 et 39,0 ± 9,2 respectivement (p = 0,003). La prévalence de l'épuisement professionnel parmi les médecins était de 9,7 % par rapport à 5,5 % parmi les infirmières (p = 0,062). Sur les 553 répondants, 247 (46,7 %) présentaient un épuisement émotionnel élevé (EE), 70 (12,7 %) présentaient une dépersonnalisation élevée (DP) et 342 (61,9 %) présentaient un faible accomplissement personnel (PA). De plus, 132 (47,3 %) médecins avaient un EE élevé, 43 (15,4 %) avaient une DP élevée et 159 (57 %) avaient un PA faible. Tandis que 115 (42 %) infirmières avaient un EE élevé, 27 (9,9 %) avaient une DP élevée et 183 (66,8 %) avaient un PA faible (p = 0,041). Une charge de travail excessive (p = 0,042) et de nombreuses années passées à un poste de travail (p = 0,002) étaient significativement associées à l'épuisement professionnel parmi les médecins, par rapport à la taille de la famille (p = 0,045) et au soutien au travail ou à la communauté (p = 0,005) parmi les infirmières. CONCLUSION: L'étude a révélé une prévalence plus élevée du burnout parmi les médecins que parmi les infirmières. Les facteurs liés au travail ont contribué de manière significative au développement du burnout. Recréer et/ ou modifier les environnements de travail est essentiel pour atténuer les effets néfastes du burnout chez les travailleurs de la santé Mots-clés: épuisement professionnel, épuisement émotionnel, dépersonnalisation, accomplissement personnel, médecins, infirmières, hôpital Universitaire, Uyo, Nigéria.

The Relationship between Substance Use Stigma and COVID-19 Vaccine Hesitancy.

Two parallel public health epidemics affecting the United States include the COVID-19 pandemic and a rise in substance use disorders (SUDs). Limited research has examined the potential relationship between these two epidemics. Our objective was therefore to perform an exploratory study in order to examine the association between public stigma toward people with a past history of opioid, methamphetamine, cocaine, and alcohol use disorder and COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 6515) completed a survey which assessed the degree of negative perceptions toward individuals with a past history of substance use disorders (referred to as substance use stigma) and COVID-19 vaccine hesitancy, along with variables such as racial prejudice, source of health news, and other demographics. We evaluated four multivariable logistic regression models to predict COVID-19 vaccine hesitancy, utilizing substance use stigma toward opioids, methamphetamine, cocaine, and alcohol use as independent variables. We found that COVID-19 vaccine hesitancy was positively associated with substance use stigma toward opioid (AOR = 1.34, p < 0.05), methamphetamine (AOR = 1.40, p < 0.01), and cocaine (AOR = 1.28, p < 0.05) use, but not alcohol use (AOR = 1.06, n.s.). Predictive models that incorporate substance use stigma may therefore improve our ability to identify individuals that may benefit from vaccine hesitancy interventions. Future research to understand the underlying reasons behind the association between substance use stigma and COVID-19 vaccine hesitancy may help us to construct combined interventions which address belief systems that promote both substance use stigma and vaccine hesitancy.

In situ hydrogen production from hydrocarbon reservoirs - modelling study.

The use of hydrogen is gaining reputation because of its many beneficial properties to the environment in comparison to hydrocarbon not minding its net energy requirement for production challenges. With most countries adopting a strategy to achieve their net-zero emissions targets, it becomes much more important to find affordable, low-carbon ways of producing hydrogen. An innovative method of producing hydrogen from hydrocarbon reservoirs while keeping the associated by-products in the reservoir has been demonstrated researchers from the University of Calgary. However, in this study, a framework for designing an in situ combustion model that considers four key hydrogen forming reactions - steam reforming, partial oxidation, autothermal reforming and pyrolysis, was developed. A set of non-linear equations obtained from chemical equilibrium analysis of the hydrogen forming reactions were solved using a Newton-Jacobi interation. Analysis of the change in Gibbs free energy of each reaction were then used as a screening tool for implementing a numerical model. Results obtained from the combustion model were then validated against results obtained from thermal reservoir simulator CMG STARS. Results from the model reveal an upward trending sinusoidal relationship between steam-carbon ratio and the amount of hydrogen yield from an in situ hydrogen production study. The combustion model could be used as a framework to design experimental analysis.

Postoperative mortality and complications in patients with and without pre-operative SARS-CoV-2 infection: a service evaluation of 24 million linked records using OpenSAFELY.

Surgical decision-making after SARS-CoV-2 infection is influenced by the presence of comorbidity, infection severity and whether the surgical problem is time-sensitive. Contemporary surgical policy to delay surgery is informed by highly heterogeneous country-specific guidance. We evaluated surgical provision in England during the COVID-19 pandemic to assess real-world practice and whether deferral remains necessary. Using the OpenSAFELY platform, we adapted the COVIDSurg protocol for a service evaluation of surgical procedures that took place within the English NHS from 17 March 2018 to 17 March 2022. We assessed whether hospitals adhered to guidance not to operate on patients within 7 weeks of an indication of SARS-CoV-2 infection. Additional outcomes were postoperative all-cause mortality (30 days, 6 months) and complications (pulmonary, cardiac, cerebrovascular). The exposure was the interval between the most recent indication of SARS-CoV-2 infection and subsequent surgery. In any 6-month window, < 3% of surgical procedures were conducted within 7 weeks of an indication of SARS-CoV-2 infection. Mortality for surgery conducted within 2 weeks of a positive test in the era since widespread SARS-CoV-2 vaccine availability was 1.1%, declining to 0.3% by 4 weeks. Compared with the COVIDSurg study cohort, outcomes for patients in the English NHS cohort were better during the COVIDSurg data collection period and the pandemic era before vaccines became available. Clinicians within the English NHS followed national guidance by operating on very few patients within 7 weeks of a positive indication of SARS-CoV-2 infection. In England, surgical patients' overall risk following an indication of SARS-CoV-2 infection is lower than previously thought.

A National Portrait of Public Attitudes toward Opioid Use in the US: A Latent Class Analysis.

BACKGROUND: Opioid overdose rates have steadily been increasing in the United States (US) creating what is considered an overdose death crisis. The US has a mixture of public health and punitive policies aimed to address opioid use and the overdose crisis, yet little is known about public opinion relating to opioid use and policy support. Understanding the intersection of public opinion about opioid use disorder (OUD) and policy can be useful for developing interventions to address policy responses to overdose deaths. METHODS: A national sample of cross-sectional data from the AmeriSpeak survey conducted from 27 February 2020 through 2 March 2020 was analyzed. Measures included attitudes toward OUD and policy beliefs. Latent class analysis, a person-centered approach, was used to identify groups of individuals endorsing similar stigma and policy beliefs. We then examined the relationship between the identified groups (i.e., classes) and key behavioral and demographic factors. RESULTS: We identified three distinct groups: (1) "High Stigma/High Punitive Policy", (2) "High Stigma/Mixed Public Health and Punitive Policy", and (3) "Low Stigma/High Public Health Policy". People with higher levels of education had reduced odds of being in the "High Stigma/High Punitive Policy" group. CONCLUSION: Public health policies are most effective in addressing OUD. We suggest targeting interventions toward the "High Stigma/Mixed Public Health and Punitive Policy" group since this group already displays some support for public health policies. Broader interventions, such as eliminating stigmatizing messaging in the media and redacting punitive policies, could reduce OUD stigma among all groups.

Impact of MiraNet® long-lasting insecticidal net against Anopheles arabiensis wild population of Northern Tanzania.

Despite high levels of pyrethroid resistance reported in malaria vectors, long-lasting insecticidal nets (LNs) still play a key role in controlling malaria transmission. This study tested the efficacy of MiraNet®, a pyrethroid-based LN against a wild population of Anopheles arabiensis in northern Tanzania. DuraNet® was used as a positive control in this evaluation. Standard WHO laboratory bioefficacy evaluations of MiraNet and DuraNet that were unwashed or had been washed 20 times indicated optimal knockdown and mortality for both net types against a susceptible strain of Anopheles gambiae s.s. Standard experimental hut evaluations were conducted to evaluate the efficacy of both nets against a wild population of An. arabiensis. The killing effect of MiraNet was 54.5% for unwashed and 50% for 20 times washed while DuraNet achieved 44.4% mortality for unwashed and 47.4% for 20 times washed against wild An. arabiensis. Both DuraNet and MiraNet exhibited significantly higher killing effects (> 44.4%). There was no significant difference in deterrence or induced exophily detected between the treatment arms for either net. Additionally, there were no adverse effects reported among hut sleepers. The results of this study indicate that the pyrethroid net MiraNet can be used effectively against wild populations of An. gambiae s.l. of low to moderate resistant levels from Northern Tanzania.

Stakeholder-engaged research is necessary across the criminal-legal spectrum.

People with lived experience of incarceration have higher rates of morbidity and mortality compared to people without history of incarceration. Research conducted unethically in prisons and jails led to increased scrutiny of research to ensure the needs of those studied are protected. One consequence of increased restrictions on research with criminal-legal involved populations is reluctance to engage in research evaluations of healthcare for people who are incarcerated and people who have lived experience of incarceration. Ethical research can be done in partnership with people with lived experience of incarceration and other key stakeholders and should be encouraged. In this article, we describe how stakeholder engagement can be accomplished in this setting, and further, how such engagement leads to impactful research that can be disseminated and implemented across disciplines and communities. The goal is to build trust across the spectrum of people who work, live in, or are impacted by the criminal-legal system, with the purpose of moving toward health equity.

How Good Is a Tactical-Grade GNSS + INS (MEMS and FOG) in a 20-m Bathymetric Survey?

This paper examines how tactical-grade Inertial Navigation Systems (INS), aided by Global Navigation Satellite System (GNSS) modules, vary from a survey-grade system in the bathymetric mapping in depths less than 20 m. The motivation stems from the advancements in sensor developments, measurement processing algorithms, and the proliferation of autonomous and uncrewed surface vehicles often seeking to use tactical-grade systems for high-quality bathymetric products. While the performance of survey-grade GNSS + INS is well-known to the hydrographic and marine science community, the performance and limitations of the tactical-grade micro-electro-mechanical system (MEMS) and tactical-grade fiber-optic-gyro (FOG) INS aided with GNSS require some study to answer the following questions: (1) How close or far is the tactical-grade GNSS + INS performance from the survey-grade systems? (2) For what survey order (IHO S-44 6th ed.) can a user deploy them? (3) Can we use them for navigation chart production? We attempt to answer these questions by deploying two tactical-grade GNSS + INS units (MEMS and FOG) and a survey-grade GNSS + INS on a survey boat. All systems collected data while operating a multibeam system with the lever-arm offsets accurately determined using a total station. The tactical-grade GNSS + INSs shared one pair of antennas for heading, while the survey-grade system used an independent antenna pair. We analyze the GNSS + INS results in sequence, examine the patch-test results, and the sensor-specific SBET-integrated bathymetric surfaces as metrics for determining the tactical-grade GNSS + INSs' reliability. In addition, we evaluate the multibeam's sounding uncertainties at different beam angles. The bathymetric surfaces using the tactical-grade navigation solutions are within 15 cm of the surface generated with the survey-grade solutions.

Dental Extractions under General Anesthesia: New Insights from Process Mining.

INTRODUCTION: Tooth extraction under general anesthetic (GA) is a global health problem. It is expensive, high risk, and resource intensive, and its prevalence and burden should be reduced where possible. Recent innovation in data analysis techniques now makes it possible to assess the impact of GA policy decisions on public health outcomes. This article describes results from one such technique called process mining, which was applied to dental electronic health record (EHR) data. Treatment pathways preceding extractions under general anesthetic were mined to yield useful insights into waiting times, number of dental visits, treatments, and prescribing behaviors associated with this undesirable outcome. METHOD: Anonymized data were extracted from a dental EHR covering a population of 231,760 patients aged 0 to 16 y, treated in the Irish public health care system between 2000 and 2014. The data were profiled, assessed for quality, and preprocessed in preparation for analysis. Existing process mining methods were adapted to execute process mining in the context of assessing dental EHR data. RESULTS: Process models of dental treatment preceding extractions under general anesthetic were generated from the EHR data using process mining tools. A total of 5,563 patients who had 26,115 GA were identified. Of these, 9% received a tooth dressing before extraction with an average lag time of 6 mo between dressing and extraction. In total, 11,867 emergency appointments were attended by the cohort with 2,668 X-rays, 4,370 prescriptions, and over 800 restorations and other treatments carried out prior to tooth extraction. DISCUSSION AND CONCLUSIONS: Process models generated useful insights, identifying metrics and issues around extractions under general anesthetic and revealing the complexity of dental treatment pathways. The pathways showed high levels of emergency appointments, prescriptions, and additional tooth restorations ultimately unsuccessful in preventing extractions. Supporting earlier publications, the study suggested earlier screening, preventive initiatives, guideline development, and alternative treatments deserve consideration. KNOWLEDGE TRANSFER STATEMENT: This study generates insights into tooth extractions under general anesthetic using process mining technologies and methods, revealing levels of extraction and associated high levels of prescriptions, emergency appointments, and restorative treatments. These insights can inform dental planners assessing policy decisions for tooth extractions under general anesthetic. The methods used can be combined with costs and patient outcomes to contribute to more effective decision-making.

Some fixed points of multivalued maps in multiplicative metric spaces.

In this manuscript, new fixed point theorems for multivalued maps, particularly α - ϕ contractions, in complete multiplicative metric spaces are proved. We further prove a fixed point theorem for multivalued mappings on a graph-equipped multiplicative metric space. Our results extend the result of Dosenovic et al. [4], and generalize the result of Ali et al. [2]. We included an example to validate our result.

Effect of Health Education on the Knowledge of Cervical Cancer and Uptake of Papanicolaou Smear Test among Teachers in Uyo, Akwa Ibom State Nigeria: An Interventional Study.

BACKGROUND: Evidence exists that the uptake of cervical cancer screening is low in Nigeria despite the availability of effective tools. This study determined the effect of health education on the knowledge of cervical cancer and uptake of Papanicolaou (Pap) smear test among teachers in public secondary schools in Uyo, Nigeria. METHODS: This was an interventional study among public secondary school teachers in Uyo, Akwa Ibom State, Nigeria. It entailed a baseline survey, administration of health education sessions on cervical cancer and its screening tests to the intervention group and a post-intervention evaluation. Data was captured using a semi-structured questionnaire and analyzed with Stata software Version 10. RESULTS: There were 185 respondents each in the interventional and control groups. The mean ages of the teachers were 38.7 ± 8.1 years and 37.1 ± 7.7 years respectively. Post-intervention, knowledge of cervical cancer symptoms increased from 10.1% to 66.5% in the intervention group compared to an increase from 7.0% to 12.0% in the control group (p< 0.001). Similarly, risk factor knowledge improved from 6.1% to 59.5% in the intervention group compared to 4.9% to 7.2% in the control group (p< 0.001). Also, the uptake of the Pap smear test increased from 11.9% to 22.2% in the intervention group (p = 0.01) compared to an increase from 4.9% to 7.0% in the control group (p=0.379). CONCLUSION: Health education brought about a significant increase in the knowledge of cervical cancer symptoms/risk factors and uptake of Pap smear test and should therefore, be encouraged among teachers in secondary schools.

CONTEXTE: Il est prouvé que le dépistage du cancer du col de l'utérus est peu pratiqué au Nigeria malgré la disponibilité d'outils efficaces. Cette étude a déterminé l'effet de l'éducation sanitaire sur la connaissance du cancer du col de l'utérus et le recours au test de Papanicolaou (Pap) chez les enseignants des écoles secondaires publiques d'Uyo, au Nigeria. MÉTHODES: Il s'agissait d'une étude interventionnelle parmi les enseignants des écoles secondaires publiques d'Uyo, Etat d'Akwa Ibom, Nigeria. Elle comportait une enquête de base, l'administration de séances d'éducation sanitaire sur le cancer du col de l'utérus et ses tests de dépistage au groupe d'intervention et une évaluation postintervention. Les données ont été recueillies à l'aide d'un questionnaire semi-structuré et analysées avec le logiciel Stata version 10. RÉSULTATS: Il y avait 185 répondants dans les groupes d'intervention et de contrôle. L'âge moyen des enseignants était respectivement de 38,7 ± 8,1 ans et 37,1 ± 7,7 ans. Après l'intervention, la connaissance des symptômes du cancer du col de l'utérus a augmenté de 10,1% à 66,5% dans le groupe d'intervention par rapport à une augmentation de 7,0% à 12,0% dans le groupe de contrôle (p< 0,001). De même, la connaissance des facteurs de risque s'est améliorée de 6,1 % à 59,5 % dans le groupe d'intervention, contre 4,9 % à 7,2 % dans le groupe témoin (p< 0,001). De même, le recours au test de Papanicolaou a augmenté de 11,9% à 22,2% dans le groupe d'intervention (p = 0,01) par rapport à une augmentation de 4,9% à 7,0% dans le groupe de contrôle (p=0,379). CONCLUSION: L'éducation à la santé a entraîné une augmentation significative de la connaissance des symptômes/facteurs de risque du cancer du col de l'utérus et du recours au test de Papanicolaou et devrait donc être encouragée parmi les enseignants des écoles secondaires. Mots clés: Cancer du col de l'utérus, symptômes, facteurs de risque, recours au test de Papanicolaou, enseignant.

Support for evidence-informed opioid policies and interventions: The role of racial attitudes, political affiliation, and opioid stigma.

Political affiliation, racial attitudes, and opioid stigma influence public support for public health responses to address opioid use disorders (OUD). Prior studies suggest public perceptions of the opioid epidemic are less racialized and less politically polarized than were public perceptions of the crack cocaine epidemic. Analyzing a cross-sectional, nationally representative sample (n = 1161 U.S. adults) from the October 2020 AmeriSpeak survey, we explored how political affiliation, racial attitudes (as captured in the Color-Blind Racial Attitudes Scale [CoBRAS]), and OUD stigma were associated with respondents' expressed views regarding four critical domains. Respondents with unfavorable attitudes towards Black Americans were less likely to support expanding Medicaid funding, increasing government spending to provide services for people living with OUD, and distributing naloxone for overdose prevention. Democratic Party affiliation was associated with greater support for all three of the above measures, and increased support for mandatory treatment, which may be seen as a substitute for more punitive interventions. Black respondents were also less likely to support expanding Medicaid funding, increasing government spending to provide services for people living with OUD, and of distributing naloxone. Our finding suggest that negative attitudes towards African-Americans and political differences remain important factors of public opinion on responding to the OUD epidemic, even after controlling for opioid stigma. Our findings also suggest that culturally-competent dialogue within politically conservative and Black communities may be important to engage public support for evidence-informed treatment and prevention.

Cultural adaptation and psychometric evaluation of the Yoruba version of the Health Literacy Questionnaire.

Background: Health literacy is an important multidimensional concept of public health concern and a determinant of health outcomes and access to healthcare which requires robust measurement. The objective of this study was to culturally adapt and establish the psychometric properties of the Yoruba version of the Health Literacy Questionnaire. Methods: A cross-sectional survey of Nigeria Yoruba speaking adults was conducted with the Health Literacy Questionnaire following its translation and adaptation. Data were subject to psychometric evaluation (confirmatory factor analysis, composite reliability, Cronbach's alpha, intra class correlation) and association with sociodemographic variables. Results: A total of 258 adults with mean age 26.7 years participated in the study. The easiest scale to score highly was 'Actively managing my health' and hardest was 'Ability to find good health information' and 'Navigating the healthcare system'. Six one-factor models fitted well without correlated residuals but the other three had a good fit after model modification. Composite reliability and Cronbach's α of ≥ 0.7 were observed for all scales, suggesting good internal consistency of the scales. Test-retest reliability of the Yoruba translation of the Health Literacy Questionnaire was moderate to good in all scales, intra class correlation ranging from 0.66 to 0.76. Conclusion: The Health Literacy Questionnaire was successfully translated and culturally adapted and demonstrated good content and construct validity and high composite reliability. The Yoruba translation of the Health Literacy Questionnaire has the potential of being a useful clinical tool for the assessment of health literacy, especially among Yoruba speaking community of Nigeria. Thereby helping to improve the health outcomes through access to healthcare.

Expanding access to HIV services during the COVID-19 pandemic-Nigeria, 2020.

BACKGROUND: To accelerate progress toward the UNAIDS 90-90-90 targets, US Centers for Disease Control and Prevention Nigeria country office (CDC Nigeria) initiated an Antiretroviral Treatment (ART) Surge in 2019 to identify and link 340,000 people living with HIV/AIDS (PLHIV) to ART. Coronavirus disease 2019 (COVID-19) threatened to interrupt ART Surge progress following the detection of the first case in Nigeria in February 2020. To overcome this disruption, CDC Nigeria designed and implemented adapted ART Surge strategies during February-September 2020. METHODS: Adapted ART Surge strategies focused on continuing expansion of HIV services while mitigating COVID-19 transmission. Key strategies included an intensified focus on community-based, rather than facility-based, HIV case-finding; immediate initiation of newly-diagnosed PLHIV on 3-month ART starter packs (first ART dispense of 3 months of ART); expansion of ART distribution through community refill sites; and broadened access to multi-month dispensing (MMD) (3-6 months ART) among PLHIV established in care. State-level weekly data reporting through an Excel-based dashboard and individual PLHIV-level data from the Nigeria National Data Repository facilitated program monitoring. RESULTS: During February-September 2020, the reported number of PLHIV initiating ART per month increased from 11,407 to 25,560, with the proportion found in the community increasing from 59 to 75%. The percentage of newly-identified PLHIV initiating ART with a 3-month ART starter pack increased from 60 to 98%. The percentage of on-time ART refill pick-ups increased from 89 to 100%. The percentage of PLHIV established in care receiving at least 3-month MMD increased from 77 to 93%. Among PLHIV initiating ART, 6-month retention increased from 74 to 92%. CONCLUSIONS: A rapid and flexible HIV program response, focused on reducing facility-based interactions while ensuring delivery of lifesaving ART, was critical in overcoming COVID-19-related service disruptions to expand access to HIV services in Nigeria during the first eight months of the pandemic. High retention on ART among PLHIV initiating treatment indicates immediate MMD in this population may be a sustainable practice. HIV program infrastructure can be leveraged and adapted to respond to the COVID-19 pandemic.

Translation and psychometric evaluation of the Yoruba version of the STarT Back tool among persons with long-term non-specific low-back pain.

Conclusion: The Y-SBT have acceptable psychometric properties. It is recommended for use among Yoruba speaking patients with LBP. Background: Translating questionnaires into local languages is essential as it aids easy accessibility and understanding of such questionnaires by patients and their health caregivers. The STarT Back Tool (SBT), validated tool used to classify subgroups of persons with Low-Back Pain, has few translated versions. We translated the STarT Back Tool into the Yoruba language and established its psychometric properties among patients with long-term non-specific Low-Back Pain. Methods: Following the Lenz protocol, the SBT was successfully cross-culturally adapted into the Yoruba language. One hundred consenting patients (mean age = 57.0±11.43 years, 55% females) took part in the validation phase, while 53 of them participated in the test-retest phase. Psychometric indices of the Y-SBT assessed showed internal consistency, intraclass correlation coefficient (ICC), ceiling and floor effects and divergent validity. Results: The sub- and total Cronbach's α score for Y-SBT was 0.704 and 0.857, respectively. The test-retest reliability of the sub- and total scores of the Y-SBT yielded an ICC of 0.82 (95% CI: 0.74 - 0.87) and 0.89 (95% CI: 0.84 - 0.93), respectively. The divergent validity for sub- and total-scores of the Y-SBT based on Quadruple Visual Analogue Scale score for on-going pain was r = 0.374 (p = 0.001) and r = 0.432 (p = 0.001), respectively. The Y-SBT had no ceiling or floor effects.

Telfairia occidentalis mitigates dextran sodium sulfate-induced ulcerative colitis in rats via suppression of oxidative stress, lipid peroxidation, and inflammation.

Ulcerative colitis (UC), a subcategory of inflammatory bowel diseases, affects more than 2 million people globally. This study sought to investigate the curative ability of aqueous leaf extract of Telfairia occidentalis (ATO) on dextran sodium sulfate (DSS)-mediated colitis in rats. UC was induced by 5% of DSS in drinking water, and the curative ability of ATO was assessed at 200 mg/kg by oral administration for 10 days. The effect of ATO was deduced on anti-inflammatory, preclinical features [disease activity index (DAI)], redox assays, and alterations both microscopic and macroscopic of the colonic mucosa. DSS mediated inflammation in colons of rats with a significant increase in nitric oxide, myeloperoxidase, IL-1ß, IL-6, and TNF-α levels compared with a control group. Lipid peroxidation was also induced following exposure of rats to DSS. There is a marked decrease in antioxidant enzymes activities in DSS group. However, treatment with ATO markedly inhibited the colonic inflammation by reversing the elevated levels of inflammatory markers. Furthermore, ATO suppressed the lipid peroxidation chain reaction by reducing the level of malondialdehyde and hydrogen peroxide. ATO attenuates DSS-induced oxidative stress by increase the level of GSH and enhancing the activities of the cytoprotective enzymes (catalase, glutathione-S-transferase, and superoxide dismutase). Taken together, ATO reduced DAI score, inhibited inflammation, suppressed lipid peroxidation, attenuated oxidative stress, and enhanced the antioxidant enzymes activities. These therapeutic effects of ATO might be due to its phytochemicals as showed in gas chromatography-mass spectroscopy results. The findings of this study indicate that aqueous leaf extract of T. occidentalis has could be a drug candidate for the treatment of UC. PRACTICAL APPLICATIONS: The study focused on the curative ability of aqueous leaf extract of Telfairia occidentalis on dextran sodium sulfate (DSS) mediated colitis in rats. The extract elicits beneficial effects against colitis via its ability to reduce mucosal inflammation, suppress lipid peroxidation, attenuate oxidative stress, enhance the antioxidant enzymes activities, and reduce both infiltration of inflammatory cells and mucosal damage in colon. This study provides scientific evidence to the therapeutic ability of aqueous leaf extract of T. occidentalis in the treatment of DSS-induced ulcerative colitis and could be a drug candidate for the treatment of inflammatory bowel diseases in humans.
