Artisanal and small-scale miners (ASMs) labour under archaic working conditions and are exposed to high levels of silica dust. Exposure to silica dust has been associated with an increased risk of tuberculosis and silicosis. ASMs are highly mobile and operate in remote areas with near absent access to health services. The main purpose of this study was to evaluate the prevalence of tuberculosis, silicosis and silico-tuberculosis among ASMs in Zimbabwe. A cross-sectional study was conducted from 1 October to 31 January 2021 on a convenient sample of 514 self-selected ASMs. We report the results from among those ASMs who attended an outreach medical facility and an occupational health clinic. Data were collected from clinical records using a precoded data proforma. Data variables included demographic (age, sex), clinical details (HIV status, GeneXpert results, outcomes of chest radiographs, history of tuberculosis) and perceived exposure to mine dust. Of the 464 miners screened for silicosis, 52 (11.2%) were diagnosed with silicosis, while 17 (4.0%) of 422 ASMs were diagnosed with tuberculosis (TB). Of the 373 ASMs tested for HIV, 90 (23.5%) were sero-positive. An HIV infection was associated with a diagnosis of silicosis. There is need for a comprehensive occupational health service package, including TB and silicosis surveillance, for ASMs in Zimbabwe. These are preliminary and limited findings, needing confirmation by more comprehensive studies.

Background and Aim: This cross-sectional study aimed to analyze the associations between different types of housing, management, and facilities on the prevalence of lame, causing lesions in smallholder dairy farms in Algeria. Materials and Methods: The on-site investigation took place between December 2012 and May 2015. All cows were locomotion scored on a four-point scale, and foot lesions causing lame were diagnosed and recorded. Factors related to the farm and the cows' conditions were also assessed. The association between the possible risk factors and lame lesions was assessed using univariate analysis. Results: Of the 349 cows evaluated, 13% were lame (lameness score ≥2), with higher lameness values recorded for the hind feet than for the forefeet. Cows without lameness were classified as healthy. The two most frequent lesion diagnoses observed in lame cows were interdigital dermatitis/heel horn erosion (ID/HE; 39%) and interdigital phlegmon (IP; 35%), followed by traumatic lesions (T; 11%), digital dermatitis (DD; 8.7%), and laminitis-related diseases (L; 6.5%). The risk of being lame was increased in large herds with cows of the Holstein breed, and those in the third parity and above. Tie housing, concrete floor, concentrate feeding, zero-grazing, and the use of foot trimming occasionally were associated with increased risk for the presence of lame lesions. The region and footbathing frequency had no association with the prevalence of lame lesions (p≥0.05). Conclusion: These results have important implications; they indicate that several aspects of housing, management, and facility design are common protective factors for the prevalence of lame lesions. These factors should be maintained correctly to not only reduce the number of lame cows in these herds but also decrease the direct and indirect costs associated with cases of lameness.

Background We aimed to describe the characteristics of sexual health clinic (SHC) attendance and sexually transmissible infection (STI) diagnoses during the Rugby World Cup (RWC) in New Zealand in 2011. Methods: SHC attendance and STI diagnoses around the time of the RWC were compared with the 5 preceding years. A cross-sectional survey conducted at SHCs in four New Zealand cities collected information from attendees having RWC-related sex. Results: Although there was no statistically significant increase in clinic attendance or STI diagnoses during the RWC compared with previous years, in these four cities, 151 individuals of 2079 attending SHCs for a new concern reported RWC-related sex. The most frequently diagnosed STIs were chlamydial infection (Chlamydia trachomatis), genital warts and genital herpes. Most attendees (74%) who had RWC-related sex had consumed three or more alcoholic drinks; 22% had used a condom. Seven percent of women reported nonconsensual sex. RWC-related sex was associated with an increased risk of STI diagnoses in men: gonorrhoea (Neisseria gonorrhoeae): relative risk (RR) = 4.9 (95% confidence interval (CI): 2.1–11.4); nonspecific urethritis: RR = 2.8 (95% CI: 1.3–5.9); chlamydial infection: RR = 1.8 (95% CI: 1.1–2.9). Using a condom was associated with a reduced risk (RR = 0.3, 95% CI: 0.1–0.9) of diagnosis with any STI among those having RWC-related sex. Conclusions: These findings highlight issues that are amenable to prevention. The continued promotion of condoms as well as a reduction in the promotion and availability of alcohol at such events may reduce sexual health risks as well as other harm.

Background: Small scale sunflower oil industries are industries which extract oil from sunflower seed. Apart from its contribution to the economic development of the nation, during extraction process much dust concentration produced and respiratory symptoms are unknown. The aim of study was to assess dust exposure and associated respiratory health symptoms among small scale sunflower oil industries workers in Singida Tanzania. Methods: A cross sectional study was conducted and 233 participants were interviewed using a modified American Thoracic Society questionnaire to assess the respiratory health symptoms. A Side Kick Casella Pump was used to collect respirable dust from a sub sample of 66 workers from the sieving section. Results: Respirable dust exposure levels for mean, and Geometrical mean was 10.45 mg/m3 (SD 13.90) and GM=5.25 mg/m3 (GSD 0.51) respectively, and 46% of the dust samples (n=66) were above the TLV of 5 mg/m3. Logistic regression analysis between measured dust and respiratory symptoms found to be statistically significant.  Higher prevalence of respiratory health symptoms were seen in those with cough (33%), cough with phlegm (46.8%) and wheezy (41.6%). Conclusion: The study concludes that, respiratory symptoms were high and dust exposure was above recommended levels of 5 mg/m3. We recommend use of appropriate RPE.

Introdução: A pobreza influencia na evolução dos pacientes com doenças crônicas, porque contribui para o seu agravamento e dificulta o acesso à assistência médica. O objetivo deste trabalho foi avaliar os aspectos relacionados à desigualdade social de pacientes em hemodiálise. Métodos: Estudo transversal com 123 pacientes em hemodiálise no Hospital Samuel Libânio – Pouso Alegre, MG, divididos, de acordo com a classe econômica, em 3 grupos: AB (n=23), C (n=60) e DE (n=40),. Foram coletados dados sociodemográficos e econômicos, antecedentes clínicos e informações sobre o acesso a serviços de saúde. Para a análise dos resultados, foi utilizada estatística analítica e descritiva. Adotou-se p £ 0,05. Resultados: O grupo AB apresentou um menor número de pacientes jovens (4,3% em AB vs 40% em C e 25% em DE, p < 0,05), um maior número de indivíduos com mais anos de escolaridade (65,3% em AB vs 18,3% em C e 2,5% em DE; p < 0,05), predomínio de pacientes com menos de um ano em tratamento de hemodiálise (65,2% em AB vs 10% em C e 5% em DE, p < 0,05), menor número de usuários do SUS (40% em C e 25% em DE vs 4,3% em AB; p < 0,05) e maior acesso ao tratamento com nefrologista (73,9% em AB vs 46,7% em C e 52,5 em DE; p < 0,05). Conclusão: Classes economicamente desfavorecidas agregam indivíduos mais jovens, com menor escolaridade, usuários do SUS, com maior tempo em hemodiálise e pior acesso ao tratamento com nefrologista.Introduction: The poverty influence on the evolution of patients with chronic diseases because it contributes to your aggravation and hinders access to health care. Our goal was to evaluate the aspects related to social inequality on hemodialysis patients. Methods: cross-sectional study with 123 patients on hemodialysis in Samuel Libânio Hospital – Pouso Alegre, MG, divided according to the economic class, into 3 groups: AB (n = 23), C (n = 60) and DE (n = 40). Were collected socio-demographic and economic data, clinical background and information about access to health services. For analysis of the results has been used statistical analytical and descriptive. We take p £ 0,05.  Results: The AB group has fewer young patients (4,3% in AB vs 40% in C and 25% in DE, p< 0,05), a greater number of individuals with more years of schooling (65,3% in AB vs 18,3% in C and 2,5% in DE; p< 0,05), predominance of patients with less than a year on haemodialysis treatment (65,2% in AB vs 10% in C and 5% in DE, p< 0,05), smaller number of users of SUS (40% in C and 25% in DE vs 4,3% in AB; p< 0,05), greater access to treatment with nephrologist (73,9% in AB vs 46,7% in C and 52,5% in DE; p< 0,05). Conclusion: Economically disadvantaged classes bring younger patients, with less schooling, users of SUS, patients with greater time on hemodialysis and worse access to treatment with nephrologist.

BACKGROUND Occupational conditions are deadly health hazards especially where dust exposure is inevitable causing chronic disabilities, impaired respiratory function and ultimately leading to death if no intensive measures are put in place. Unhealthy practices and negative attitudes rise in the number of cases of pneumoconiosis due to poor health education and awareness strategies. Pneumoconiosis is not only a health problem but also a social and economic burden on the livelihood of people living in mining areas around the globe. OBJECTIVE to assess knowledge, attitude and practices of miners and post-occupational miners towards pneumoconiosis in Wusakile Township, Kitwe, Zambia. METHODS A cross-sectional study was employed to conduct a research in Wusakile Township and a questionnaire was customized in order to syphon data relevant to the study as well to be brief. The study was conducted among 73 participants who were randomly selected among miners and post-occupational miners and all satisfied the inclusion criteria. Both quantitative and qualitative methods were used to collect data. The data was entered and analysed using IBM SPSS software version 23. RESULTS Among 73 participants interviewed, 33.99% of participants had poor knowledge on the complications of pneumoconiosis. However, despite this poor knowledge, all participants had an idea about pneumoconiosis particularly silicosis. 13.70% of the respondents had bad practices towards pneumoconiosis while 86.30% had some good practices towards pneumoconiosis. Of the total participants, 19.18% of the participants had a negative attitude towards pneumoconiosis. Correlation between the level of education and practices of participants using Pearson Chi-Square, a p value of 0.021 (significant) was found ruling out the null hypothesis. CONCLUSIONS Information about pneumoconiosis and awareness programs towards pneumoconiosis are not widely disseminated among miners and post-occupational miners. There is still a significant number of participants who need to be educated more about pneumoconiosis and its complications so that attitude and practices are improved and also promote full community participation by involving competent health professionals to help in implementing preventive measures.

ObjectiveTo determine the rates of asymptomatic viral carriage and seroprevalence of SARS-CoV-2 antibodies in healthcare workers.DesignA cross-sectional study of asymptomatic healthcare workers undertaken on 24/25 April 2020.SettingUniversity Hospitals Birmingham NHS Foundation Trust (UHBFT), UK.Participants545 asymptomatic healthcare workers were recruited while at work. Participants were invited to participate via the UHBFT social media. Exclusion criteria included current symptoms consistent with COVID-19. No potential participants were excluded.InterventionParticipants volunteered a nasopharyngeal swab and a venous blood sample that were tested for SARS-CoV-2 RNA and anti-SARS-CoV-2 spike glycoprotein antibodies, respectively. Results were interpreted in the context of prior illnesses and the hospital departments in which participants worked.Main outcome measureProportion of participants demonstrating infection and positive SARS-CoV-2 serology.ResultsThe point prevalence of SARS-CoV-2 viral carriage was 2.4% (n=13/545). The overall seroprevalence of SARS-CoV-2 antibodies was 24.4% (n=126/516). Participants who reported prior symptomatic illness had higher seroprevalence (37.5% vs 17.1%, χ2=21.1034, p<0.0001) and quantitatively greater antibody responses than those who had remained asymptomatic. Seroprevalence was greatest among those working in housekeeping (34.5%), acute medicine (33.3%) and general internal medicine (30.3%), with lower rates observed in participants working in intensive care (14.8%). BAME (Black, Asian and minority ethnic) ethnicity was associated with a significantly increased risk of seropositivity (OR: 1.92, 95% CI 1.14 to 3.23, p=0.01). Working on the intensive care unit was associated with a significantly lower risk of seropositivity compared with working in other areas of the hospital (OR: 0.28, 95% CI 0.09 to 0.78, p=0.02).Conclusions and relevanceWe identify differences in the occupational risk of exposure to SARS-CoV-2 between hospital departments and confirm asymptomatic seroconversion occurs in healthcare workers. Further investigation of these observations is required to inform future infection control and occupational health practices.

ObjectiveTo test if patients recovering from COVID-19 are at increased risk of mental morbidities and to what extent such risk is exacerbated by illness severity.DesignPopulation-based cross-sectional study.SettingIceland.ParticipantsA total of 22 861 individuals were recruited through invitations to existing nationwide cohorts and a social media campaign from 24 April to 22 July 2020, of which 373 were patients recovering from COVID-19.Main outcome measuresSymptoms of depression (Patient Health Questionnaire), anxiety (General Anxiety Disorder Scale) and posttraumatic stress disorder (PTSD; modified Primary Care PTSD Screen for DSM-5) above screening thresholds. Adjusting for multiple covariates and comorbidities, multivariable Poisson regression was used to assess the association between COVID-19 severity and mental morbidities.ResultsCompared with individuals without a diagnosis of COVID-19, patients recovering from COVID-19 had increased risk of depression (22.1% vs 16.2%; adjusted relative risk (aRR) 1.48, 95% CI 1.20 to 1.82) and PTSD (19.5% vs 15.6%; aRR 1.38, 95% CI 1.09 to 1.75) but not anxiety (13.1% vs 11.3%; aRR 1.24, 95% CI 0.93 to 1.64). Elevated relative risks were limited to patients recovering from COVID-19 that were 40 years or older and were particularly high among individuals with university education. Among patients recovering from COVID-19, symptoms of depression were particularly common among those in the highest, compared with the lowest tertile of influenza-like symptom burden (47.1% vs 5.8%; aRR 6.42, 95% CI 2.77 to 14.87), among patients confined to bed for 7 days or longer compared with those never confined to bed (33.3% vs 10.9%; aRR 3.67, 95% CI 1.97 to 6.86) and among patients hospitalised for COVID-19 compared with those never admitted to hospital (48.1% vs 19.9%; aRR 2.72, 95% CI 1.67 to 4.44).ConclusionsSevere disease course is associated with increased risk of depression and PTSD among patients recovering from COVID-19.

ObjectiveThe study aimed to assess the prevalence of stunting, wasting, underweight and associated factors in orphaned children under 5 years old.DesignA cross-sectional study.SettingGambella City, Ethiopia.ParticipantsA sample of 419 under 5 orphaned children included in the study. Eligible households with orphans had selected using a systematic random sampling method. The lottery method was used when more than one eligible study participants live in the household. An OR with 95% CI was performed to measure the strength of association between each dependent variable and independent variables. Variables with p<0.05 were declared statistically significant.Primary outcomeThe main outcome of this study was the prevalence of undernutrition among orphaned under 5 and its associated factors.ResultsPrevalence of stunting, wasting and underweight in orphan children under 5 were 12.2%, 37.8% and 21.7%, respectively. The prevalnce of wasting peaks among age group of 36–47 months (42.5%), whereas underweight peaks in 48–59 months (27.7%). Food insecurity, wealth index, family size, vitamin A supplementation, diarrhoea, fever 2 weeks before the survey, children under 5 and parents’ death were associated with undernutrition.ConclusionThe prevalence of stunting, wasting and underweight among orphan children under 5 was significantly high. Multisectoral collaborative efforts towards access to health services, improving income-generating activities, micronutrient supplementation and social support and protection targeting orphan and vulnerable populations have to be built up.

Abstract Background Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. Methods This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. Results Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18–1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14–1.98), hypertension (OR: 1.32, 95%CI: 1.03–1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02–1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06–1.65). Conclusion In this study, BF did not affect decreasing the prevalence of Mets and its components.
