Ethnic differences in metabolic syndrome in high-income countries: A systematic review and meta-analysis.

This review aimed to systematically quantify the differences in Metabolic Syndrome (MetS) prevalence across various ethnic groups in high-income countries by sex, and to evaluate the overall prevalence trends from 1996 to 2022. We conducted a systematic literature review using MEDLINE, Web of Science Core Collection, CINAHL, and the Cochrane Library, focusing on studies about MetS prevalence among ethnic groups in high-income countries. We pooled 23 studies that used NCEP-ATP III criteria and included 147,756 healthy participants aged 18 and above. We calculated pooled prevalence estimates and 95% confidence intervals (CI) using both fixed-effect and random-effect intercept logistic regression models. Data were analysed for 3 periods: 1996-2005, 2006-2009, and 2010-2021. The pooled prevalence of MetS in high-income countries, based on the NCEP-ATP III criteria, was 27.4% over the studied period, showing an increase from 24.2% in 1996-2005 to 31.9% in 2010-2021, with men and women having similar rates. When stratified by ethnicity and sex, ethnic minority women experienced the highest prevalence at 31.7%, while ethnic majority women had the lowest at 22.7%. Notably, MetS was more prevalent in ethnic minority women than men. Among ethnic minorities, women had a higher prevalence of MetS than men, and the difference was highest in Asians (about 15 percentage points). Among women, the prevalence of MetS was highest in Asians (41.2%) and lowest in Blacks/Africans (26.7%). Among men, it was highest in indigenous minority groups (34.3%) and lowest among in Blacks/Africans (19.8%). MetS is increasing at an alarming rate in high-income countries, particularly among ethnic minority women. The burden of MetS could be effectively reduced by tailoring interventions according to ethnic variations and risk profiles.

Seasonal variation of mycotoxin levels in poultry feeds and feed ingredients in Oyo State, Nigeria.

Mycotoxins pose a major problem to poultry production as a result of feed contamination which has deleterious consequences such as production losses and human health risks. A total of 158 chicken feed samples were randomly collected from 46 consenting poultry farms in Oyo State throughout the wet season (April-October; 91 samples) and the dry season (November-March; 67 samples), including compounded feed (n = 129) and feed ingredients (n = 29). Samples were promptly transported to the laboratory in sterile plastic vials for lateral flow assay for mycotoxins using six different commercial mycotoxin test kits each for aflatoxin B1, zearalenone, deoxynivalenol, ochratoxin A, fumonisin, and T-2 toxin/HT-2 toxin. Summary values of mycotoxin levels (µg/kg) in the feedstuffs were represented as frequency or median (and range). Fisher exact or Mann-Whitney U tests were carried out where appropriate at α = 0.05. Every sample contained at least four mycotoxins. Aflatoxins and fumonisin co-occurred in 80% of the samples. Aflatoxin and fumonisin concentrations were above the permissible limits in 32.9% and 18.4% respectively in feedstuff sampled in the dry season while the values were 17.1% and 6.3% respectively during the wet season. Among feed ingredients, peanut cake and maize had the highest median concentration of aflatoxin and fumonisin, respectively. Median aflatoxin concentration in the feedstuff was significantly higher than the permissible limit irrespective of season. There is a need to frequently monitor mycotoxin levels of feed and feed ingredients and improve storage system for feed ingredients in order to reduce the risk associated with high mycotoxin intake in poultry.

Ameliorative effects of glycine on cobalt chloride-induced hepato-renal toxicity in rats.

BACKGROUND: The important roles of liver and kidney in the elimination of injurious chemicals make them highly susceptible to the noxious activities of various toxicants including cobalt chloride (CoCl2 ). This study was designed to investigate the role of glycine in the mitigation of hepato-renal toxicities associated with CoCl2 exposure. METHODS: Forty-two (42) male rats were grouped as Control; (CoCl2 ; 300 ppm); CoCl2 + Glycine (50 mg/kg); CoCl2 + Glycine (100 mg/kg); Glycine (50 mg/kg); and Glycine (100 mg/kg). The markers of hepatic and renal damage, oxidative stress, the antioxidant defense system, histopathology, and immunohistochemical localization of neutrophil gelatinase associated lipocalin (NGAL) and renal podocin were evaluated. RESULTS: Glycine significantly reduced the markers of oxidative stress (malondialdehyde content and H2 O2 generation), liver function tests (ALT, AST, and ALP), markers of renal function (creatinine and BUN), and decreased the expression of neutrophil gelatinase-associated lipocalin (NGAL) and podocin compared with rats exposed to CoCl2 toxicity without glycine treatment. Histopathology lesions including patchy tubular epithelial necrosis, tubular epithelial degeneration and periglomerular inflammation in renal tissues, and severe portal hepatocellular necrosis, inflammation, and duct hyperplasia were observed in hepatic tissues of rats exposed to CoCl2 toxicity, but were mild to absent in glycine-treated rats. CONCLUSION: The results of this study clearly demonstrate protective effects of glycine against CoCl2 -induced tissue injuries and derangement of physiological activities of the hepatic and renal systems in rats. The protective effects are mediated via augmentation of total antioxidant capacity and upregulation of NGAL and podocin expression.

Sharing decisions on reproductive goals: A mixed-methods study of the views of women who have cystic fibrosis.

BACKGROUND: There are complex medical, psychological, social and economic aspects to becoming a parent with Cystic Fibrosis (CF). A shared decision-making (SDM) approach could help women with CF make informed decisions about their reproductive goals that are sensitive to their individual values and preferences. This study investigated capability, opportunity, and motivation to participate in SDM from the perspective of women with CF. METHODS: Mixed-methods design. An international online survey was completed by 182 women with CF, to investigate participation in SDM in relation to reproductive goals, and measures of capability (information needs), opportunity (social environment) and motivation (SDM attitudes and self-efficacy) to engage in SDM. Twenty-one women were interviewed using a visual timelines method to explore their SDM experiences and preferences. Qualitative data were analysed thematically. RESULTS: Women with higher decision self-efficacy reported better experiences of SDM relating to their reproductive goals. Decision self-efficacy was positively associated with social support, age, and level of education, highlighting inequalities. Interviews indicated that women were highly motivated to engage in SDM, but their capability was compromised by lack of information, perception of insufficient opportunities for focused discussions about SDM. CONCLUSIONS: Women with CF are keen to engage in SDM about reproductive health, but currently lack sufficient information and support to do so. Interventions at patient, clinician and system levels are needed to support capability, opportunity and motivation to engage equitably in SDM in relation to their reproductive goals.

Preparedness of primary health care facilities on implementation of essential non-communicable disease interventions in osun state south-west Nigeria: a rural-urban comparative study.

BACKGROUND: Global response to the growing burden of non-communicable diseases (NCDs) in developing countries includes the development of WHO Package of Essential Non-communicable Disease Interventions (WHO PEN) for Primary Health Care (PHC). The study assessed the level of preparedness of PHC facilities on implementation of essential NCD interventions in rural and urban Local Government Areas (LGAs) of Osun State, Nigeria. METHODS: The study was a comparative cross-sectional survey. Information was collected from heads of 33 rural and 33 urban PHC facilities and through direct observation on the domains of staff training, basic equipment, diagnostics and essential medicines for cardiovascular diseases, diabetes and chronic respiratory diseases (CRDs) using a semi-structured interviewer administered questionnaire. RESULTS: Manual sphygmomanometer was found in similar proportions (84.8%) of PHC facilities in rural and urban LGAs. Glucometer was available in 45.5% of the PHC facilities in urban and 33.3% of the PHC facilities in the rural LGAs, the difference was not statistically significant (χ2 = 1.015; p = 0.314). Basic equipment for CRDs were not available in majority of PHC facilities in both locations. Moduretic tablets were the most reported essential NCD medicines, available in 15% of PHC facilities in rural LGAs and none in urban LGAs. The anti-diabetic medicines were not available in any of the PHC facilities in both locations. More than 90% (≥ 30) of the PHC facilities in both locations were not prepared to implement essential interventions for each NCD across domains of staff training and essential medicines. Overall, 97.0% of the PHC facilities in the rural LGAs and all the PHC facilities in urban LGAs were not prepared on implementation of essential interventions for the three NCDs. CONCLUSION: The level of preparedness of the PHC facilities on implementation of essential NCD interventions in the rural and urban LGAs of Osun State is very low. Government needs to strengthen the PHC system by providing needed essential medicines, basic diagnostics, equipment, and training of clinical health care workers for implementation of essential NCD interventions in the state.

Leaf extract of Anacardium occidentale ameliorates biomarkers of neuroinflammation, memory loss, and neurobehavioral deficit in N(ω)-nitro-L-arginine methyl ester (L-NAME) treated rats.

PURPOSE: Anacardium occidentale commonly known as Cashew is a plant that is widely used in African traditional medicine. It is endowed with phytochemical constituents that are responsible for its medicinal properties. METHODS: Twenty-five male Wistar rats were grouped as follows: Control (Group A), Group B (L-NAME 40 mg/kg), Group C (100 mg/kg Anacardium occidentale extract plus 40 mg/kg L-NAME), Group D (200 mg/kg extract plus 40 mg/kg L-NAME) and Group E (10 mg/kg of Lisinopril plus 40 mg/kg L-NAME). The animals were treated with oral administration of either the extracts or Lisnopril daily for 4 weeks. Neuro-behavioural tests such as the Morris Water Maze and Hanging Wire Grip tests were carried out to evaluate memory/spatial learning and muscular strength, respectively. Makers of oxidative stress, antioxidant enzymes and immunohistochemical staining of Glial Fibrillary Acidic Protein and Ionised Calcium Binding Adaptor molecule 1 were assessed. RESULTS: L-NAME administration caused significant increases in biomarkers of oxidative stress, decreased antioxidant status, acetylcholinesterase activity, altered neuro-behavioural changes, astrocytosis, and microgliosis. However, Anacardium occidentale reversed exaggerated oxidative stress biomarkers and improved neuro-behavioural changes. CONCLUSIONS: Combining all, Anacardium occidentale enhanced brain antioxidant defence status, improved memory and muscular strength, thus, suggesting the neuroprotective properties of Anacardium occidentale.

Naringin administration mitigates oxidative stress, anemia, and hypertension in lead acetate-induced cardio-renal dysfunction in cockerel chicks.

Lead is one of the major pollutants that is harmful to both animals and humans. It is found in every aspect of the environment such as the air, water, and soil. This pollutant affects both wild and domestic birds. Naringin has an active principle called flavonoid that has been found to have medicinal properties, mostly because of its antioxidant and metal chelating properties. This study was carried out to investigate the protective effect of naringin as an antioxidant against lead-induced anemia, cardio and nephrotoxicity, and hypertension. This study also aimed at elucidating the use of naringin as a heavy metal binder in poultry feed. Thirty-six cockerel chicks were used for this study, and randomly grouped into six groups per group; group A served as the control, group B received Pb-only (300 ppm), group C (Pb and naringin; 80 mg/kg), group D (Pb and naringin; 160 mg/kg), group E (naringin 80 mg/kg), and group F (naringin 160 mg/kg), respectively, for 8 weeks. Lead (Pb) was administered via drinking water, while naringin was administered via oral gavage. Lead acetate intoxication precipitated anemia as indicated by significant reductions in the values of PCV, RBC, and Hb concentration in lead-treated chicks when compared with the controls. Also, lead administration induced hypertension together with increased oxidative stress, depletion of the antioxidant defense system, reduced nitric oxide production, and an increase in high blood pressure. Immunohistochemistry indicated high expressions of cardiac troponin, renal angiotensin-converting enzymes, and renal neutrophil gelatinase-associated lipocalin. Treatment with naringin corrected anemia, reduced oxidative stress, improved antioxidant system, reduced high blood pressure, and offered protection against lead acetate-induced cardio-renal dysfunction in cockerel chicks. We recommend that naringin should be incorporated poultry feeds as a metal binder.

Naringin abrogates angiotensin-converting enzyme (ACE) activity and podocin signalling pathway in cobalt chloride-induced nephrotoxicity and hypertension.

PurposeThe persistent and alarming rates of increase in cardiovascular and renal diseases caused by chemicals such as cobalt chloride (CoCl2) in mammalian tissues have led to the use of various drugs for the treatment of these diseases. This study aims at evaluating the nephron-protective action of Naringin (NAR), a metal-chelating antioxidant against CoCl2-induced hypertension and nephrotoxicity.MethodsForty-two male Wistar rats were randomly distributed to seven rats of six groups and classified into Group A (Control), Group B (300 part per million; ppm CoCl2), Group C (300 ppm CoCl2 + 80 mg/kg NAR), Group D (300 ppm CoCl2 + 160 mg/kg NAR), Group E (80 mg/kg NAR), and Group F (160 mg/kg NAR). NAR and CoCl2 were administered via oral gavage for seven days. Biomarkers of renal damage, oxidative stress, antioxidant status, blood pressure parameters, immunohistochemistry of renal angiotensin-converting enzyme and podocin were determined.ResultsCobalt chloride intoxication precipitated hypertension, renal damage, and oxidative stress. Immunohistochemistry revealed higher expression of angiotensin-converting enzyme (ACE) and podocin in rats administered only CoCl2.ConclusionTaken together, the antioxidant and metal-chelating action of Naringin administration against cobalt chloride-induced renal damage and hypertension could be through abrogation of angiotensin-converting enzyme and podocin signalling pathway.

Immunohistochemical and morphological changes associated with hepatic damage in lead acetate-induced toxicity and mitigatory properties of naringin in cockerel chicks.

Lead (Pb) toxicity constitutes a major health hazard to both humans and animals especially in the developing countries. It is a ubiquitous environmental contaminant found in the air essentially because of unregulated mining and other industrial activities. Lead can be found naturally in the soil thus, contaminating crops for human and animal food, as well as run-off water and air pollution. Intensively and extensively reared domestic chickens are exposed to contamination via inhalation and ingestion of contaminated food materials. Naringin, a product from citrus plant has been described to possess excellent metal chelating ability. Naringin is rich in flavonoid with attendant antioxidant, anti-autophagy, anti-inflammatory, hepatoprotective and cardio-nephroprotective properties. This study was conducted to investigate the hepatoprotective and modulation of oxidative stress in commercial cockerel chickens by Naringin. Thirty-six commercial cockerel chickens were randomly assigned into six groups A-F of six birds each viz: Group A served as control group while groups B, C, and D received Lead acetate at 300 ppm via drinking water continuously till the end of the experiment. In addition, groups C and D were treated with Naringin at 80 mg/kg and 160mg/kg, respectively, via oral gavage for 8 weeks. Groups E and F were administered naringin only at 80mg/kg and 160mg/kg respectively for eight weeks. Pb toxicity induced degenerative changes in the histological sections as well as, higher expression of hepatic caspase 3 as shown by immunohistochemistry. There was increased oxidative stress markers (H2O2, MDA) and depletion of the antioxidant defense system markers SOD, GPx, GSH, and GST. It concluded that Co- treatment with Naringin ameliorated oxidative stress, enhanced antioxidant defense system, reduced the expression of hepatic caspase 3 thus, offering protection against lead acetate-induced derangements in the liver of commercial cockerel chickens.

Organisational and individual readiness for change to respectful maternity care practice and associated factors in Ibadan, Nigeria: a cross-sectional survey.

OBJECTIVES: This study assessed health providers' organisational and individual readiness for change to respectful maternity care (RMC) practice and their associated factors in Ibadan Metropolis, Nigeria. DESIGN: A cross-sectional survey using standardised structured instruments adapted from the literature. SETTING: Nine public health facilities in Ibadan Metropolis, Nigeria, 1 December 2019-31 May 2020. PARTICIPANTS: 212 health providers selected via a two-stage cluster sampling. OUTCOMES: Organisational readiness for change to RMC (ORCRMC) and individual readiness for change to RMC (IRCRMC) scales had a maximum score of 5. Multiple linear regression was used to identify factors influencing IRCRMC and ORCRMC. We evaluated previously identified predictors of readiness for change (change valence, informational assessments on resource adequacy, core self-evaluation and job satisfaction) and proposed others (workplace characteristics, awareness of mistreatment during childbirth, perceptions of women's rights and resource availability to implement RMC). Data were adjusted for clustering and analysed using Stata V.15. RESULTS: The providers' mean age was 44.0±9.9 years with 15.4±9.9 years of work experience. They scored high on awareness of women's mistreatment (3.9±0.5) and women's perceived rights during childbirth (3.9±0.5). They had high ORCRMC (4.1±0.9) and IRCRMC (4.2±0.6), both weakly but positively correlated (r=0.407, 95% CI: 0.288 to 0.514, p<0.001). Providers also had high change valence (4.5±0.8) but lower perceptions of resource availability (2.7±0.7) and adequacy for implementation (3.3±0.7). Higher provider change valence and informational assessments were associated with significantly increased IRCRMC (ß=0.40, 95% CI: 0.11 to 0.70, p=0.015 and ß=0.07, 95% CI: 0.01 to 0.13, p=0.032, respectively), and also with significantly increased ORCRMC (ß=0.47, 95% CI: 0.21 to 0.74, p=0.004 and ß=0.43, 95% CI: 0.22 to 0.63, p=0.002, respectively). Longer years of work experience (ß=0.08, 95% CI: 0.01 to 0.2, p=0.024), providers' monthly income (ß=0.08, 95% CI: 0.02 to 0.15, p=0.021) and the health facility of practice were associated with significantly increased ORCRMC. CONCLUSION: The health providers studied valued a change to RMC and believed that both they and their facilities were ready for the change to RMC practice.

Directly observed and reported respectful maternity care received during childbirth in public health facilities, Ibadan Metropolis, Nigeria.

Respectful maternity care (RMC) is believed to improve women's childbirth experience and increase health facility delivery. Unfortunately, few women in low- and middle-income countries experience RMC. Patient surveys and independent observations have been used to evaluate RMC, though seldom together. In this study, we assessed RMC received by women using two methodologies and evaluated the associated factors of RMC received. This was a cross-sectional study conducted in nine public health facilities in Ibadan, a large metropolis in Nigeria. We selected 269 pregnant women by cluster sampling. External clinical observers observed them during childbirth using the 29-item Maternal and Child Health Integrated Program RMC observational checklist. The same women were interviewed postpartum using the 15-item RMC scale for self-reported RMC. We analysed total RMC scores and RMC sub-category scores for each tool. All scores were converted to a percentage of the maximum possible to facilitate comparison. Correlation and agreement between the observed and reported RMC scores were determined using Pearson's correlation and Bland-Altman analysis respectively. Multiple linear regression was used to identify factors associated with observed RMC. No woman received 100% of the observed RMC items. Self-reported RMC scores were much higher than those observed. The two measures were weakly positively correlated (rho = 0.164, 95%CI: 0.045-0.278, p = 0.007), but had poor agreement. The lowest scoring sub-categories of observed RMC were information and consent (14.0%), then privacy (28.0%). Twenty-eight percent of women (95%CI: 23.0% -33.0%) were observed to be hit during labour and only 8.2% (95%CI: 4.0%-18.0%) received pain relief. Equitable care was the highest sub-category for both observed and reported RMC. Being employed and having completed post-secondary education were significantly associated with higher observed RMC scores. There were also significant facility differences in observed RMC. In conclusion, the women reported higher levels of RMC than were observed indicating that these two methodologies to evaluate RMC give very different results. More consensus and standardisation are required in determining the cut-offs to quantify the proportion of women receiving RMC. The low levels of RMC observed in the study require attention, and it is important to ensure that women are treated equitably, irrespective of personal characteristics or facility context.

A qualitative inquiry into pregnant women's perceptions of respectful maternity care during childbirth in Ibadan Metropolis, Nigeria.

Women's perceptions of respectful maternity care (RMC) are critical to its definition and measurement globally. We evaluated these in relation to globally defined RMC norms. We conducted a descriptive study involving eight focus group discussions with 50 pregnant women attending antenatal clinic at one primary and one secondary health facility each in the North-west and South-west local government areas of Ibadan Metropolis, Nigeria. One focus group each with primigravidae and multiparas were held per facility between 21 and 25 October 2019. Shakibazadeh et al's 12 domains of RMC served as the thematic framework for data analysis. The women's perceptions of RMC resonated well with seven of its domains, emphasising provider-client inter-personal relationships, preserving their dignity, effective communication, and non-abandonment of care, but with mixed perceptions for two domains. However, their perceptions deviated for four domains, namely maintaining privacy and confidentiality; ensuring continuous access to family support such as birth companions; obtaining informed consent; and respecting women's choices about mobility during labour, food and fluid intake, and birth position. The physical environment was not mentioned as contributing to an experience of RMC. Whilst the perceptions of the Nigerian women studied about RMC were similar to those accepted internationally, there were significant deviations which may be related to cultural differences and societal disparities. Different interpretations of RMC may influence women's demand for such care in different settings and challenge strategies for promoting a universal standard of care.

Practice, Perceptions, and Prospects of Mammography Screening in Nigeria: Insights From a National Survey of Female Health Workers.

BACKGROUND: Mammography, the most preferred tool for breast cancer screening, has very poor uptake in Nigeria, even among health workers. No nationwide study has been done to ascertain this. This study sought to determine the current perceptions and practices of Nigerian female health care practitioners on mammography screening across different types and levels of health care institutions in the country's 6 geopolitical zones. METHODS: This cross-sectional online survey was conducted using Google Forms distributed among Nigerian female health workers via online professional associations and networks. Descriptive and inferential statistics were done using SPSS version 20. RESULTS: A total of 562 respondents, with mean age of 41.30 ± 9.8 years, were surveyed. About half (50.3%) were doctors, with majority practicing in southern Nigeria. A mammography screening utilization rate of 15.4% was found, with majority having their first mammography long after attaining the age of eligibility. As of the time of the survey, only 24.8% of tertiary health workers had access to functional mammography machines at their place of work. Majority of female doctors (78%) never refer eligible patients for mammography, although nearly all (98.6%) were willing to do so. About 54% of those who have had a previous mammography screening vs. 17% who have not had 1 would recommend it to others. Majority of respondents recommended annual mammography from the age of forty at a subsidized cost. CONCLUSION: Nigerian female health workers have limited access to mammography and consequently do not screen often. Efforts must be made to make 'charity begin at home'.

How secured and safe is the sanitation and hygiene services in a maximum-security correctional facility in Southwest Nigeria: a descriptive cross-sectional study.

Poorly maintained living conditions and infrastructure are the banes of Nigerian prisons. The study investigated its environmental conditions and the prevalent diseases among inmates.The descriptive, cross-sectional study enrolled 420-inmates through a multistage sampling technique. Pre-tested instruments were administered and results presented with descriptive and logistic regression to identify predictors of toilet-cleaning and handwashing practices at P∝0.05.The mean(±SD) age and modal inmates/cell were 30±7.2 years and 36. Most inmates were males (97%), await-trial (79%) and lives in overcrowded cells (58%). Sixty-nine percent of free-cells has pour-flush toilets and 36% waits for 2-5 minutes before accessing toilets.Fifty-three percent of inmates clean latrines with water and soap, 71% burn solid waste while handwashing period-prevalence was 36%. Religion, toilet-cleaning, and education were predictors of handwashing while types of toilets and access predict toilet-cleaning behaviour. Malaria (81.1%) and scabies (7.3%) were endemic. The prison rehabilitation shall satisfy basic life needs and promote prisoners' health.

Knowledge of primary healthcare workers regarding the prevention and control of non-communicable diseases in Osun State, Nigeria: A rural-urban comparison.

BACKGROUND: There is a rising burden of non-communicable diseases (NCDs) in the sub-Saharan Africa, and calls for integration of management of selected NCDs with primary healthcare (PHC) have been unrelenting. Cost-effective interventions for the prevention and control of NCDs can be delivered at PHC facilities in low-resource settings by clinical healthcare workers (HCWs). AIM: This study compared the knowledge of HCWs in PHC facilities regarding the prevention and control of NCDs in rural and urban local government areas (LGAs) of Osun State. SETTING: A comparative cross-sectional study was conducted amongst 400 eligible HCWs recruited using a multistage sampling technique in PHC facilities of six rural and six urban LGAs. METHODS: A pretested self-administered case-scenarios questionnaire was used to assess the knowledge of HCWs regarding the prevention and control of three selected NCDs (diabetes, hypertension and chronic respiratory diseases). Both descriptive and inferential statistics were conducted. RESULTS: The mean knowledge scores of HCWs regarding the prevention and control of the three NCDs were 17.76 ± 4.41 in rural and 17.62 ± 4.02 in urban LGAs out of 30 maximum scores. The proportion of HCWs with adequate knowledge in the rural LGAs (31.0%) was slightly higher than the urban LGAs (23.0%); however, it was not statistically significant (χ2 = 3.247; p = 0.072). The major determinants of adequate knowledge include cadre of HCWs, location, years in practice with professional certificate, NCD training course attendance and reported experience managing diabetic patients. CONCLUSION: The HCWs in PHC facilities in rural and urban LGAs of Osun State, Nigeria, had a poor knowledge regarding the prevention and control of NCDs. Training and re-training of less-skilled HCWs in the PHC facilities using relevant WHO NCD protocols and guidelines are imperatives to improve their knowledge about the prevention and control of NCDs.

Work Practices and Health Problems of Spray Painters Exposed to Organic Solvents in Ile-Ife, Nigeria.

BACKGROUND: Automobile spray painters in Nigeria are exposed to organic solvents due to the hazardous nature of their work. Inadequate use of personal protective equipment (PPE) may intensify exposure to high levels of chemical hazards with resultant health problems. OBJECTIVES: The present study assessed PPE use and work practices and compared work-related health problems of spray painters and controls in Ile-Ife, Nigeria. METHODS: A cross-sectional study was conducted among 120 spray painters and 120 controls (electronic technicians). Data on socio-demographics, work practices, knowledge about organic solvent-related hazards and self-reported health symptoms were obtained using a semi-structured questionnaire. Clinical examinations were performed for all respondents and the composition of organic solvents in paints and paint products were derived from material safety data sheets. RESULTS: All respondents were male, and the mean age was 32.7±13.8 years for painters and 33.9±15.5 years for controls. Few (7.5%) painters perceived their use of PPE to be adequate. All spray painters worked in enclosed workshops and N-butyl acetate was the most commonly used organic solvent. Spray painters reported excessive tear production, recurrent cough, and short-term memory loss more frequently than controls (P<0.05). In addition, 89% of painters noticed paint-stained sputum immediately after spray painting. The prevalence ratio of respiratory symptoms was higher in spray painters than controls (prevalence ratio=21.0, CI=2.9-153.6). On clinical examination, more spray painters had corneal opacity and dry skin when compared with controls (P<0.05). CONCLUSIONS: Spray painters in the study area worked amidst chemical hazards and had poor use of PPE. Exposure to organic solvents may be responsible for the higher prevalence of self-reported health problems among spray painters. Interventions to enforce the use of PPE and improve the knowledge of organic solvent-related hazards among spray painters are essential. PARTICIPANT CONSENT: Obtained. ETHICS APPROVAL: Ethical approval to conduct the study was obtained from the Health Research and Ethics Committee of the Institute of Public Health, Obafemi Awolowo University, Ile-Ife Nigeria (HREC No: IPHOAU/12/463). COMPETING INTERESTS: The authors declare no competing financial interests.

Perceived Effect of Occupational Safety Measures on Workers' Performance in Warri Refining and Petrochemical Company, Delta State, Nigeria.

INTRODUCTION: Occupational safety measures when put in place in organizations are expected to increase the productivity of employees and drive organizations to better performance. This study was aimed at assessing the perception of workers at the Warri Refining and Petrochemical Company (WRPC) on the effect of implemented occupational safety measures on their individual and organizational performance. MATERIALS AND METHODS: The study was cross-sectional in design conducted at the WRPC, Delta state, Nigeria, among 236 workers of the WRPC selected via a simple random sampling technique across different job cadres (junior, senior, and management) in the organization. Data were collected using a semi-structured self-administered questionnaire and analyzed using the descriptive and inferential statistical tests of the SPSS version 20 with statistical significance set at P < 0.05. RESULTS: The mean age of respondents was 43 ± 2.26 years with a male-to-female ratio of 1.8:1. More than 50% of the respondents attested that occupational safety measures had been well implemented at the WPRC. Almost all the respondents, 219 (92.8%) and 224 (94.9%), agreed that occupational safety measures in place and trainings on safety measures had improved individual worker's performance, respectively. Respondents' length of service and job cadres were significantly associated with their perceived effect of the existing occupational safety measures at the WRPC on individual worker and organizational performance (P < 0.001). They were also significantly associated with their perceived effect of the neglect of these safety measures on high labor turnover rate (P < 0.001). CONCLUSION: Occupational safety measures were perceived to have positively affected workers' and organizational performance.

Incidence, risk factors, and health service burden of sequelae of campylobacter and non-typhoidal salmonella infections in England, 2000-2015: A retrospective cohort study using linked electronic health records.

BACKGROUND: Reactive arthritis, irritable bowel syndrome (IBS), Guillain-Barré syndrome, ulcerative colitis, and Crohn's disease may be sequelae of Campylobacter or non-typhoidal Salmonella (NTS) infections. Proton pump inhibitors (PPI) and antibiotics may increase the risk of gastrointestinal infections (GII); however, their impact on sequelae onset is unclear. We investigated the incidence of sequelae, their association with antibiotics and PPI prescription, and assessed the economic impact on the NHS. METHODS: Data from the Clinical Practice Research Datalink for patients consulting their GP for Campylobacter or NTS infection, during 2000-2015, were linked to hospital, mortality, and Index of Multiple Deprivation data. We estimated the incidence of sequelae and deaths in the 12 months following GII. We conducted logistic regression modelling for the adjusted association with prescriptions. We compared differences in resource use and costs pre- and post-infection amongst patients with and without sequelae. FINDINGS: Of 20,471 patients with GII (Campylobacter 17,838), less than 2% (347) developed sequelae, with IBS (268) most common. Amongst Campylobacter patients, those with prescriptions for PPI within 12 months before and cephalosporins within 7-days before/after infection had elevated risk of IBS (adjusted odds ratio [aOR] 2.1, 1.5-2.9) and (aOR 3.6, 1.1-11.7) respectively. Campylobacter sequelae led to ∼ £1.3 million, (£750,000, £1.7 million) in additional annual NHS expenditure. INTERPRETATION: Sequelae of Campylobacter and NTS infections are rare but associated with increased NHS costs. Prior prescription of PPI may be a modifiable risk factor. Incidence of sequelae, healthcare resource use and costs are essential parameters for future burden of disease studies.
