Introdução: Os acidentes ocupacionais com material biológico representam um problema de saúde pública. A exposição ocupacional dos profissionais da saúde configura-se como um risco de transmissão de diversos patógenos. Na literatura, há carência de estudos que analisem o perfil dos acidentes com material biológico nos médicos da atenção primária. Objetivo: Buscou-se compreender o perfil epidemiológico dos acidentes com material biológico em médicos da atenção primária em Minas Gerais. Métodos: Estudo epidemiológico descritivo com análise do perfil dos acidentes com material biológico em médicos da atenção primária em Minas Gerais, utilizando dados secundários. Resultados: No período analisado, foram registrados 111 acidentes com material biológico, dos quais 54% ocorreram somente em 2020 e 2021. A maioria dos casos deu-se em mulheres (59%), e os tipos mais frequentes de exposição foram mucosa (38%) e percutânea (33%). Dos médicos, 23% não possuíam esquema vacinal contra a hepatite B completo. Em média, em 36% dos acidentes os testes sorológicos foram negativos e em 61% não foram realizados ou o campo foi ignorado/deixado em branco. Em apenas 7,2% dos casos a quimioprofilaxia foi indicada, mas ressaltam-se os registros ignorados ou em branco. Mais da metade dos acidentados não emitiu a Comunicação de Acidente de Trabalho (CAT). Conclusões: Os acidentes com material biológico predominam em médicas e nas formas de exposição mucosa e percutânea. Investimentos em medidas de biossegurança e educação permanente são necessários para prevenir casos e estimular sua notificação.

Introduction: Occupational accidents with biological material represent a public health problem. The occupational exposure of health professionals represents a risk of transmission of various pathogens. In the literature, there is a lack of studies that analyze the profile of accidents with biological material among primary health care physicians. Objective: We aimed to understand the epidemiological profile of accidents involving biological material among primary health care physicians in Minas Gerais, Brazil. Methods: Descriptive epidemiological study that analyzed the profile of accidents with biological material among primary health care doctors in Minas Gerais, using secondary data. Results: In the period analyzed, 111 accidents with biological material were recorded, of which 54% occurred only in 2020 and 2021. Most cases occurred in women (59%) and the most frequent types of exposure were mucosal (38%) and percutaneous (33%). About a quarter (23%) of physicians did not have a complete immunization record for hepatitis B. On average, in 36% of accidents serological tests were negative and in 61% they were not performed or the field was ignored/left blank. In only 7.2% of cases, chemoprophylaxis was indicated, but ignored or blank records stood out. More than half of the victims did not fill out a work accident report. Conclusions: Accidents with biological material predominate in female doctors and in forms of mucosal and percutaneous exposure. Investments in biosafety measures and permanent education are necessary to prevent cases and encourage their notification.

Epidemiology and viral loads of respiratory syncytial virus in hospitalized children prior to and during COVID-19 pandemic in Hangzhou, China.

Non-pharmaceutical interventions (NPIs) implemented to control SARS-CoV-2 have significantly influenced the activity of respiratory pathogens. This study investigated epidemiological changes among hospitalized patients with respiratory syncytial virus (RSV) before (2017-2019) and during (2020-2022) the COVID-19 pandemic in Hangzhou, China. We also examined viral load distribution across demographic and temporal variables. Nasopharyngeal swabs were collected and RSV loads were quantified using reverse transcriptase polymerase chain reaction (RT-qPCR). RSV epidemic characteristics, seasonal dynamics, and viral load distributions were compared between pre- and pandemic years. General linear models were employed to assess associations between viral loads and age. Among 19 742 cases, 1576 and 2092 tested positive during the pre- and pandemic years, respectively. From February to July 2020, the implementation of NPIs led to the cessation of RSV circulation. However, after these measures were relaxed, RSV cases resurged over two consecutive seasons during the pandemic, notably affecting older children compared to those in the pre-pandemic years (1.00 years, IQR: 0.50-2.00 vs. 0.58 years, IQR: 0.27-1.00, p < 0.001). Specifically, in 2021-2022, an off-season resurgence of RSV began earlier (mid-June), lasted longer (40 weeks), and involved more positive cases (1238 cases) than both 2020-2021 and pre-pandemic years. Viral load distribution demonstrated a clear age-related relationship in both pre- and pandemic years, with younger children consistently showing higher viral loads, independently of gender and season (all p-values for trends <0.001). These findings highlight the impact of NPIs on RSV epidemiology and underscore the need to prioritize RSV infection prevention in younger children from the perspective of viral load.

Past, current, and future trends in the prevalence of primary sclerosing cholangitis and inflammatory bowel disease across England (2015-2027): a nationwide, population-based study.

Background: Primary sclerosing cholangitis (PSC) is one of the leading indications for liver transplantation in Europe, and a major risk factor for cancer in inflammatory bowel disease (IBD). However, it is not known how the epidemiology of PSC will change as that of IBD evolves. The aim of this study is to provide nationwide statistics on the past and current prevalence of PSC and IBD across England, and forecast how this is likely to change over time. Methods: We accessed and analysed a nationwide population-based administrative healthcare registry, which houses prospectively accrued data since April 1st 2001. In so doing, the past and current prevalence of PSC-IBD and IBD alone was determined among 18-60-year-olds in England, alongside average annual percentage change rates (AAPC), between the 1st of January 2015 and 2020. Past and current prevalence data, alongside trends in incidence and event-free survival rates, were then used to forecast future prevalence between 2021 and 2027. Findings: In 2015, the prevalence of PSC with prior IBD diagnosis was 5.0 per 100,000 population, rising to 5.7 when including those with IBD diagnosed after PSC. In 2020, prevalence increased to 7.6 (8.6 accounting for IBD developing after PSC), yielding an AAPC of 8.8. In 2027, PSC-IBD prevalence is forecast to be 11.7 (95% prediction interval [PI]: 10.8-12.7), and 13.3 when accounting for IBD developing after PSC (AAPC: 6.4; 95% PI: 5.3-7.5). Comparatively, the prevalence of IBD alone rose among 18-60-year-olds from 384.3 in 2015 to 538.7 in 2020 (AAPC 7.0), and forecast to increase to 742.5 by 2027 (95% PI: 736.4-748.0; AAPC: 4.7, 95% PI: 4.6-4.8). Interpretation: The rate of growth in PSC-IBD is predicted to exceed IBD-alone. Further research is needed to understand changes in disease epidemiology, including aetiological drivers of developing (invariably progressive) liver disease in IBD, and the implications of rising case burden on health care resources. Funding: This study was supported by an unrestricted grant provided by Gilead Sciences.

Advancing research on Blastocystis through a One Health approach.

Blastocystis is the most prevalent intestinal eukaryotic microorganism with significant impacts on both human and animal health. Despite extensive research, its pathogenicity remains controversial. The COST Action CA21105, " Blastocystis under One Health" (OneHealthBlastocystis), aims to bridge gaps in our understanding by fostering a multidisciplinary network. This initiative focuses on developing standardised diagnostic methodologies, establishing a comprehensive subtype and microbiome databank, and promoting capacity building through education and collaboration. The Action is structured into five working groups, each targeting specific aspects of Blastocystis research, including epidemiology, diagnostics, 'omics technologies, in vivo and in vitro investigations, and data dissemination. By integrating advances across medical, veterinary, public, and environmental health, this initiative seeks to harmonise diagnostics, improve public health policies, and foster innovative research, ultimately enhancing our understanding of Blastocystis and its role in health and disease. This collaborative effort is expected to lead to significant advancements and practical applications, benefiting the scientific community and public health.

Blastocystis is a common microorganism found in the intestines of humans and animals. Its role in causing disease is still debated among scientists. The " Blastocystis under One Health" initiative aims to unite experts from human medicine, veterinary science, and environmental science to better understand this microorganism and its health effects. The project focuses on improving diagnostic methods, creating a comprehensive database of Blastocystis samples, and analysing its genetic and molecular makeup. Researchers will also study how Blastocystis interacts with other gut microbes and impacts gut health. Additionally, the initiative aims to educate healthcare professionals and the public about Blastocystis. By working together, scientists hope to develop better ways to diagnose, treat (if necessary), and/or prevent Blastocystis infections, ultimately protecting both human and animal health and enhancing our understanding of this widespread microorganism.

Clinical Analysis of Patients Diagnosed with Cutaneous Sporotrichosis in China.

Purpose: This study aimed to improve the understanding of sporotrichosis by analyzing the epidemiological characteristics, clinical manifestations, mycological features, and pathological characteristics of the disease in eastern China. Methods: Clinical data of 49 patients diagnosed with cutaneous sporotrichosis in dermatology clinics over a 20-year period were collected and analyzed retrospectively. The analysis included patient demographics, occupations, clinical types, lesion sites, misdiagnosis rates, laboratory investigations, treatment and outcomes. Results: The study included 22 male and 27 female patients, with a mean age of 52.4 years. Farmers (42.86%) and manual workers (28.57%) had a higher risk of infection. The most common clinical types were lymphocutaneous (30.61%) and fixed (69.39%), predominantly affecting the face and upper limbs. Misdiagnosis as other infectious skin diseases occurred in 35 patients (71.43%). Fungal culture and histopathological examination were important diagnostic tools. Treatment with oral itraconazole for three months led to relief and regression of the skin lesions in most patients, although a few experienced recurrences. Conclusion: Cutaneous sporotrichosis mainly affects individuals working in agriculture and manual labour, with lymphocutaneous and fixed types being the predominant clinical manifestations. The high misdiagnosis rate emphasizes the importance of early recognition, accurate diagnosis and standardized treatment for the prognosis and cure of sporotrichosis. Fungal culture and histopathological examination are essential for diagnosis, and oral itraconazole is an effective treatment option.

Retreatment and Anti-tuberculosis Therapy Outcomes in Brazil Between 2015 and 2022: A Nationwide Study.

Background: Adherence to anti-tuberculosis treatment (ATT) in Brazil remains a challenge in achieving the goals set by the World Health Organization (WHO). Patients who are lost to follow-up during treatment pose a significant public health problem. This study aimed to investigate the factors associated with unfavorable ATT outcomes among those undergoing retreatment in Brazil. Methods: We conducted an observational study of patients aged ≥18 years with tuberculosis (TB) reported to the Brazilian National Notifiable Disease Information System between 2015 and 2022. Clinical and epidemiologic variables were compared between the study groups (new cases and retreatment). Regression models identified variables associated with unfavorable outcomes. Results: Among 743 823 reported TB cases in the study period, 555 632 cases were eligible, consisting of 462 061 new cases and 93 571 undergoing retreatments (44 642 recurrent and 48 929 retreatments after loss to follow-up [RLTFU]). RLTFU (odds ratio [OR], 3.96 [95% confidence interval {CI}, 3.83-4.1]) was a significant risk factor for any type of unfavorable ATT. Furthermore, RLTFU (OR, 4.93 [95% CI, 4.76-5.11]) was the main risk factor for subsequent LTFU. For death, aside from advanced age, living with HIV (OR, 6.28 [95% CI, 6.03-6.54]) was the top risk factor. Conclusions: Retreatment is a substantial risk factor for unfavorable ATT outcomes, especially after LTFU. The rates of treatment success in RLTFU are distant from the WHO End TB Strategy targets throughout Brazil. These findings underscore the need for targeted interventions to improve treatment adherence and outcomes in persons who experience RLTFU.

Retrospective study on neonatal seizures in a tertiary center of northern Italy after ILAE classification: Incidence, seizure type, EEG and etiology.

OBJECTIVE: We aimed to evaluate epidemiology, seizure type, EEG, and etiology of neonatal seizures (NS) in a tertiary neonatal intensive care unit. METHODS: Data on infants with a neurophysiological confirmation of NS were collected between 2009 and 2022. Seizure types and epileptic syndromes were classified by the ILAE classification and EEG by the Italian Neonatal Seizure Collaborative Network (INNESCO) score. RESULTS: Out of 91,253 neonates, 145 presented with NS; 69.7 % were born at term and 30.3 % were preterm infants. The incidence of NS in neonates born at our center was 1.2 per 1,000 live newborns (96/80697 neonates) while in the entire neonatal population admitted to our center it was 1.6 per 1,000 live births, increasing with lower preterm age. Compared to previous studies, we found a lower proportion of hypoxic-ischemic encephalopathy (HIE) (23.4 %) and a higher rate of genetic contribution (26.2 %). The infection rate was higher in preterm (31.8 %) than in full term (9.9 %) infants. Electrographic seizures were associated with acute provoked seizures (35.9 %), preterm age (52.3 %), and HIE (52.9 %). Vascular etiology was associated with focal clonic seizures (56.8 %). Non-structural neonatal genetic epilepsy was associated with sequential seizures (68.2 %), particularly KCNQ2 and SCN2A epilepsy. Background EEG was abnormal in all HIE, infections (85.7 %) and metabolic NS (83.3 %). In genetic epilepsy, background EEG depended on the epileptic syndrome: normal in 80 % of self-limited neonatal epilepsy and abnormal in 77.8 % of developmental and epileptic encephalopathy. Electroclinical seizures were associated with focal onset, while electrographic seizures correlated with a multifocal onset. CONCLUSIONS: A low incidence of HIE and a high incidence of genetic etiology were observed in our cohort of NS. Seizure type and EEG features are fundamental to address etiology.

Higher ultraviolet light exposure is associated with lower mortality: An analysis of data from the UK biobank cohort study.

We aimed to examine associations between ultraviolet (UV) exposure and mortality among older adults in the United Kingdom (UK). We used data from UK Biobank participants with two UV exposures, validated with measured vitamin D levels: solarium use and annual average residential shortwave radiation. Associations between the UV exposures, all-cause and cause-specific mortality were examined as adjusted hazard ratios. The UV exposures were inversely associated with all-cause, cardiovascular disease (CVD) and cancer mortality. Solarium users were also at a lower risk of non-CVD/non-cancer mortality. The benefits of UV exposure may outweigh the risks in low-sunlight countries.

Prevalence and types of cancer in older Indians: A multicentric observational study across 17 institutions in India.

The global demographic and epidemiological transition have led to a rapidly increasing burden of cancer, particularly among older adults. There are scant data on the prevalence and demographic pattern of cancer in older Indian persons. This was a multicentric observational study conducted between January 2019 and December 2020. Data were retrieved from existing electronic databases to gather information on two key variables: the total number of patients registered with oncologists and the number of patients aged 60 years and above. The primary objective was to determine the percentage of older adults among patients with cancer served by these hospitals. Secondary objectives included understanding the prevalence of different types of cancer in the older population, and the sex- and geographic distribution of cancer in older Indian patients. We included 272,488 patients with cancer from 17 institutes across India. Among them, 97,962 individuals (36 %) were aged 60 years and above. The proportion of older adults varied between 20.6 % and 53.6 % across the participating institutes. The median age of the older patients with cancer was 67 (interquartile range, 63-72) years. Of the 54,281 patients for whom the details regarding sex were available, 32,243 (59.4 %) were male. Of the 56,903 older patients, head and neck malignancies were the most prevalent, accounting for 11,158 cases (19.6 %), followed by breast cancer (6260 cases, 11 %), genitourinary cancers (6242 cases, 10.9 %), lung cancers (6082 cases, 10.7 %), hepatopancreaticobiliary (6074, 10.7 %), and hematological malignancies (5226 cases, 9.2 %). Over one-third of Indian patients with cancer are aged 60 years and above, with a male predominance. Head and neck, breast, and genitourinary cancers are the most prevalent in this age group. Characterizing the burden of cancer in older adults is crucial to enable tailored interventions and additional research to improve the care and support for this vulnerable population.

Global prevalence of nonalcoholic fatty liver disease: an updated meta-analysis on 78 million population over 38 countries.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a global health challenge, with a rising rate in line with other metabolic diseases. We aimed to assess the global prevalence of NAFLD in adult and pediatric populations. METHODS: PubMed, Scopus and Web of Science databases were systematically searched up to May 2023. Heterogeneity was assessed using Cochran's Q test and I2 statistics, and random-effects model was used for meta-analysis. Analyses were performed using STATA version 18. RESULTS: A total of 479 studies with 78,001,755 participants from 38 countries were finally included. The global prevalence of NAFLD was estimated to be 30.2% (95% CI: 28.7-31.7%). Regionally, the prevalence of NAFLD was as follows: Asia 30.9% (95% CI: 29.2-32.6%), Australia 16.1% (95% CI: 9.0-24.8%), Europe 30.2% (95% CI: 25.6-35.0%), North America 29% (95% CI: 25.8-32.3%), and South America 34% (95% CI: 16.9-53.5%). Countries with a higher human development index (HDI) had significantly lower prevalence of NAFLD (coefficient = -0.523, p = 0.005). Globally, the prevalence of NAFLD in men and women was 36.6% (95% CI: 34.7-38.4%) and 25.5% (95% CI: 23.9-27.1%), respectively. The prevalence of NAFLD in adults, adults with obesity, children, and children with obesity was 30.2% (95% CI: 28.8-31.7%), 57.5% (95% CI: 43.6-70.9%), 14.3% (95% CI: 10.3-18.8%), and 38.0% (95% CI: 31.5-44.7%), respectively. CONCLUSION: The prevalence of NAFLD is remarkably high, particularly in countries with lower HDI. This substantial prevalence in both adults and children underscores the need for disease management protocols to reduce the burden.

On the host specificity and genetic diversity of Iodamoeba bütschlii: Observations from short amplicon-based next-generation sequencing.

Iodamoeba is a single-celled intestinal parasite, which is common in humans in certain parts of the world, and also in pigs. For the first time, we provide DNA-based evidence of goat, dromedary, fallow deer, and donkey as hosts of Iodamoeba and show that Iodamoeba-specific nucleotide sequences from these four hosts do not appear to overlap with those of humans, unlike those from pigs. We moreover show that similar strains of Iodamoeba can be found in Madagascar, Western Sahara, and Ecuador and that intra-sample diversity is typically extensive across even small fragments of DNA in both human and non-human hosts.

Is precarious employment an occupational hazard? Evidence from Ontario, Canada.

OBJECTIVES: To examine the association between precarious employment and risk of occupational injury or illness in Ontario, Canada. METHODS: We combined accepted lost-time compensation claims from the Workplace Safety and Insurance Board with labour force statistics to estimate injury and illness rates between January 2016 and December 2019. Precarious employment was imputed using a job exposure matrix and operationalised in terms of temporary employment, low wages, irregular hours, involuntary part-time employment and a multidimensional measure of 'low', 'medium', 'high' and 'very high' probabilities of exposure to precarious employment. Negative binomial regression models examined exposure to precarious employment in relation to risk of occupational injury or illness. RESULTS: After adjusting for age, sex and year, all indicators of precarious employment were associated with increased risk of injury or illness. Workers with 'high' and 'very' high' exposure to precarious employment presented a nearly threefold risk of injury or illness (rate ratio (RR): 2.81, 95% CI 2.73 to 2.89; RR: 2.82, 95% CI 2.74 to 2.90). Further adjustment for physical demands and workplace hazards attenuated associations, though a statistically and substantively significant exposure-outcome relationship persisted for workers with 'high' and 'very high' exposures to precarious employment (RR: 1.65, 95% CI 1.58 to 1.72; RR: 2.00, 95% CI 1.92 to 2.08). CONCLUSIONS: Workers exposed to precarious employment are more likely to sustain a lost-time injury or illness in Ontario, Canada. Workplace health and safety strategies should consider the role of precarious employment as an occupational hazard and a marker of work injury risk.

Chronic Obstructive Pulmonary Disease and Obstructive Sleep Apnea Overlap Syndrome: An Update on the Epidemiology, Pathophysiology, and Management.

This review provides an up-to-date summary of the prevalence, pathophysiology, diagnosis, and treatment of the chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) overlap syndrome (OVS). The presence of OVS is high in patients with COPD and in patients with OSA and is associated with profound nocturnal oxygen desaturation and systemic inflammation. There is a high prevalence of cardiovascular disease among patients with OVS and this likely contributes to increased mortality. Observational studies suggest that positive airway pressure therapy improves survival and reduces COPD exacerbations; however, randomized controlled trials will be required to confirm these findings.

Comprehensive contact tracing during an outbreak of alpha-variant SARS-CoV-2 in a rural community reveals less viral genomic diversity and higher household secondary attack rates than expected.

Sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes throughout the COVID-19 pandemic has generated a wealth of data on viral evolution across populations, but only a few studies have so far explored SARS-CoV-2 evolution across large connected transmission networks. Here, we couple data from SARS-CoV-2 sequencing with contact tracing data from an outbreak with a single origin in a rural Norwegian community where samples from all exposed persons were collected prospectively. A total of 134 nasopharyngeal samples were positive by PCR. Among the 121 retrievable genomes, 81 were identical to the genome of the introductor, thus demonstrating that genomics beyond clustering genotypically similar viral genomes to confirm relatedness offers limited additional value to manual contact tracing. In the cases where mutations were discovered, five small genetic clusters were identified. We observed a household secondary attack rate of 77%, with 92% of household members infected among households with secondary transmission, suggesting that SARS-CoV-2 introduction into large families is likely to affect all household members. IMPORTANCE: In outbreak investigations, obtaining a full overview of infected individuals within a population is seldom achieved. We here present an example where a single introduction of B1.1.7 SARS-CoV-2 within a rural community allowed for tracing of the virus from an introductor via dissemination through larger gatherings into households. The outbreak occurred before widespread vaccination, allowing for a "natural" outbreak development with community lockdown. We show through sequencing that the virus can infect up to five consecutive persons without gaining mutations, thereby showing that contact tracing seems more important than sequencing for local outbreak investigations in settings with few alternative introductory transmission pathways. We also show how larger households where a child introduced transmission appeared more likely to promote further spread of the virus compared to households with an adult as the primary introductor.

Contribution of involuntary job loss to the burden of depressive symptoms over two decades in a national study of aging adults.

OBJECTIVES: In recent decades, risk of job loss in America after age 50 has been high, potentially causing significant stress during the period preceding retirement. Yet no study has quantified the burden of clinically relevant depressive symptoms attributable to job loss in this age group over this period or identified the most vulnerable populations. METHODS: Participants aged 50+ in the Health and Retirement Study (recruited 1992-2016) who were employed and scored <5 on the Center for Epidemiologic Studies Depression 8-item scale (CESD-8) at baseline (N=18,571) were followed for depressive symptoms until they first had CESD-8≥5 or died, or through the 2018 survey. Parametric g-formula analyses examined the difference in cumulative risk of having CESD-8≥5 if there had been no involuntary job loss compared to the observed scenario, adjusting for sex, race/ethnicity, age, and dynamic measures of recent marriage end (divorce or widowhood), having a working spouse, assets/debt, and health changes. RESULTS: We estimated that risk of CESD-8≥5 would have been 1.1% (95%CI[0.55,1.37]) lower if no involuntary job loss had occurred; job loss accounted for 11% of the total burden among those who lost a job. Stronger associations were observed for women (1.2% [0.7,1.8] vs. men 0.5% [0.2,1.1]), white respondents (1.0% [0.6,1.5] vs. Black respondents 0.5% [-0.1,1.4]), and those in the lowest quartile of baseline assets (1.1% [0.4,1.9] vs. wealthiest quartile 0.5% [-0.4,0.9]). DISCUSSION: Involuntary job loss is associated with high depressive symptom burden in older persons, suggesting that screening and intervention soon after job loss may help mitigate depression.

Examining breast cancer screening recommendations in Canada: The projected resource impact of screening among women aged 40-49.

OBJECTIVE: To quantify the resource use of revising breast cancer screening guidelines to include average-risk women aged 40-49 years across Canada from 2024 to 2043 using a validated microsimulation model. SETTING: OncoSim-Breast microsimulation platform was used to simulate the entire Canadian population in 2015-2051. METHODS: We compared resource use between current screening guidelines (biennial screening ages 50-74) and alternate screening scenarios, which included annual and biennial screening for ages 40-49 and ages 45-49, followed by biennial screening ages 50-74. We estimated absolute and relative differences in number of screens, abnormal screening recalls without cancer, total and negative biopsies, screen-detected cancers, stage of diagnosis, and breast cancer deaths averted. RESULTS: Compared with current guidelines in Canada, the most intensive screening scenario (annual screening ages 40-49) would result in 13.3% increases in the number of screens and abnormal screening recalls without cancer whereas the least intensive scenario (biennial screening ages 45-49) would result in a 3.4% increase in number of screens and 3.8% increase in number of abnormal screening recalls without cancer. More intensive screening would be associated with fewer stage II, III, and IV diagnoses, and more breast cancer deaths averted. CONCLUSIONS: Revising breast cancer screening in Canada to include average-risk women aged 40-49 would detect cancers earlier leading to fewer breast cancer deaths. To realize this potential clinical benefit, a considerable increase in screening resources would be required in terms of number of screens and screen follow-ups. Further economic analyses are required to fully understand cost and budget implications.

Epidemiology of dental caries in internally displaced children during wartime in Ukraine.

OBJECTIVE: Aim: To conduct a comprehensive analysis of the oral health status of this vulnerable population in order to collect objective data that will contribute to the development of effective strategies for maintaining and improving oral health in wartime conditions. PATIENTS AND METHODS: Material and Methods: This epidemiological study was carried out within the initial 6 months of the full-scale invasion of the country. The oral health indices of 1050 internally displaced children, aged 3 to 17 years, seeking dental care at the Municipal Children Dental Clinic in Poltava, were analyzed. RESULTS: Results: The total sample comprised 620 children aged 6-11 years (mean = 8.5, SD = 0.76), with a gender distribution of 52% boys and 48% girls. The participants were divided into three age groups: Group I (6-7 years), Group II (8-9 years), and Group III (10-11 years). The average prevalence of dental caries, as measured by the dmft + DMFT index, was 76.5%, with prevalence increasing with age. Specifically, the prevalence of dental caries based on the dmft index was lower in children of Group III (66.6%) compared to Group I (79.49%). CONCLUSION: Conclusions: The analysis of the oral status among internally displaced children aged 6-11 years revealed higher dental caries prevalence and intensity compared to local children. Notably, children aged 6-7 years showed a high rate of caries in temporary teeth.

Coping style as a risk factor for future alcohol use disorder: A 16-year longitudinal study in a Canadian military sample.

BACKGROUND: Coping strategies used in response to stress have the potential to influence the development of mental health disorders, including alcohol use disorders. The current study investigated whether coping strategies placed an individual at greater likelihood for developing a future alcohol use disorder. METHODS: This study used data from the Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey; a nationally representative 16-year follow-up survey, with initial data collected in the 2002 Canadian Community Health Survey - Canadian Forces Supplement. The total sample from the two datasets included 2941 individuals who were Regular Force members in 2002. Coping styles included problem-focused, avoidant, and self-medication. Adjusted logistic regression analyses examined relationships between coping style (in 2002) and alcohol use disorders (developed between 2002 and 2018). RESULTS: Self-medication coping in 2002 was associated with any alcohol disorder since last interview (i.e., 2002-2018) (AOR 1.26; 95 % CI, 1.02-1.57) and during the past year (adjusted odds ratios [AOR 1.26; 95 % CI, 1.08-1.47]), as well as past-year binge drinking (AOR 1.19; 95 % CI, 1.09-1.29). Problem-focused coping was protective against past-year alcohol abuse (AOR 0.84; 95 % CI, 0.71-1.00) and any alcohol use disorder (AOR 0.87; 95 % CI 0.76-1.00). CONCLUSION: Coping styles were strongly associated with future alcohol use disorders. Notably, results show the risk extended over a 16-year period. Findings suggest the use of self-medicating coping strategies places an individual at increased risk of developing alcohol use disorders, while problem-focused coping may decrease future risk of alcohol use disorders.

Dynamics of Neisseria gonorrhoeae transmission among female sex workers and clients: A mathematical modeling study.

BACKGROUND: This study aimed to examine the transmission dynamics of Neisseria gonorrhoeae (NG) in heterosexual sex work networks (HSWNs) and the impact of variation in sexual behavior and interventions on NG epidemiology. METHODS: The study employed an individual-based mathematical model to simulate NG transmission dynamics in sexual networks involving female sex workers (FSWs) and their clients, primarily focusing on the Middle East and North Africa region. A deterministic model was also used to describe NG transmission from clients to their spouses. RESULTS: NG epidemiology in HSWNs displays two distinct patterns. In the common low-partner-number HSWNs, a significant proportion of NG incidence occurs among FSWs, with NG prevalence 13 times higher among FSWs than clients, and three times higher among clients than their spouses. Interventions substantially reduce incidence. Increasing condom use from 10 % to 50 % lowers NG prevalence among FSWs, clients, and their spouses from 12.2 % to 6.4 %, 1.2 % to 0.5 %, and 0.4 % to 0.2 %, respectively. Increasing symptomatic treatment coverage among FSWs from 0 % to 100 % decreases prevalence from 10.6 % to 4.5 %, 0.8 % to 0.4 %, and 0.3 % to 0.1 %, respectively. Increasing asymptomatic treatment coverage among FSWs from 0 % to 50 % decreases prevalence from 8.2 % to 0.4 %, 0.6 % to 0.1 %, and 0.2 % to 0.0 %, respectively, with very low prevalence when coverage exceeds 50 %. In high-partner-number HSWNs, prevalence among FSWs saturates at a high level, and the vast majority of incidence occurs among clients and their spouses, with a limited impact of incremental increases in interventions. CONCLUSION: NG epidemiology in HSWNs is typically a "fragile epidemiology" that is responsive to a range of interventions even if the interventions are incremental, partially efficacious, and only applied to FSWs.

Chagas Disease: Epidemiology, Diagnosis, and Treatment.

PURPOSE OF REVIEW: This review seeks to describe the updates in the literature - particularly with regards to the epidemiology and diagnosis of Chagas disease. Additionally, this paper describes updates to the antiparasitic treatment for Chagas disease. RECENT FINDINGS: With regards to changing epidemiology, autochthonous cases are being found within the USA in addition to Latin America. Additionally, there appears to be more intermixing of discrete typing units-meaning, they are not confined to specific geographic regions. Screening for Chagas disease is recommended in persons who lived in areas with endemic Chagas, persons wtih family member diagnosed with Chagas Disease, persons who have lived in homes of natural material in Latin America, and persons with history of kissing bug bites. Treatment for the parasitic infection remains limited to benznidazole and nifurtimox, and the role of these treatments in Chagas cardiomyopathy has not yet been definitively defined. Finally, indications for and management of heart transplant in the setting of Chagas disease are discussed. FUTURE RESEARCH: Use of antiparasitics during chronic chagas disease should be further explored. Additionally, future research identifying other markers of infection would be valuable to defining cure from infection.
