Global burden of atrial fibrillation attributable to high body mass index from 1990 to 2021: findings from the Global Burden of Disease Study 2021.

OBJECTIVES: To assess the global burden of atrial fibrillation (AF) attributable to high body mass index (BMI) from 1990 to 2021 and analyze its spatiotemporal distribution characteristics. STUDY DESIGN: An observational study based on GBD 2021 data. METHODS: Data on AF burden due to high BMI were obtained from the Global Burden of Disease Study (GBD) 2021. Estimated annual percentage change (EAPC) was calculated to evaluate temporal trends in age-standardized rates of deaths and disability-adjusted life years (DALYs) over 30 years. RESULTS: In 2021, high BMI-related AF caused 27,000 deaths and 725,000 DALYs globally, a 376% increase since 1990. Females and the elderly (aged 70+) bore a higher burden. Upper-middle-income regions surpassed high-income regions in AF burden. Australasia had the highest age-standardized rates, while High-income Asia Pacific and South Asia had the lowest. South Asia showed rapid growth in age-standardized death rates. CONCLUSION: The global burden of high BMI-related AF varies across regions and time, threatening global health, especially for females and the elderly. Targeted strategies are needed to reduce AF and obesity.

Clinical characteristics of Behçet's syndrome in Shanghai database: Baseline data of a cross-sectional cohort study.

OBJECTIVE: Behçet's syndrome (BS) is a variant vessel vasculitis that can involve multiple organs, with highly heterogeneous clinical manifestations. This study aims to analyze baseline data of BS patients to enhance the comprehension of its clinical features. METHODS: This study included 1216 registered cases of BS patients referred to Huadong Hospital affiliated with Fudan University. Each patient was thoroughly assessed and recorded for demographic data, clinical manifestations, gastrointestinal endoscope, imaging, etc. RESULTS: Significant gender differences were observed in clinical manifestations. Pseudofolliculitis (p < .001), uveitis (p = .003), vascular (p < .001), and cardiovascular involvement (p < .001) were significantly more prevalent in male BS patients, while genital ulcers (p = .011) and erythema nodosum (p = .009) were more common among the female. Furthermore, pseudofolliculitis (44.3%, 37.4% vs. 25.0%, p < .001), pathergy test positivity (37.0%, 24.5% vs. 12.6%, p < .001), and uveitis (18.8%, 18.4% vs. 11.2%, p < .001) showed higher incidence rates in the 16-35 years age group. Vascular involvement (11.1%, 18.0% vs. 15.8%, p < .001) notably increased in the 36-50 years age group. Additionally, the ISG diagnostic criteria were more likely to be met in the 16-35 age group (OR: 2.039, 95% CI: 1.581-2.631, p < .001), whereas the ICBD criteria were less likely to be met in the 16-35 age group (OR: 0.266, 95% CI: 0.150-0.474, p < .001). CONCLUSIONS: This study provided data on the baseline of clinical features of BS in a single center, BS patients presented significant heterogeneity, showing different manifestations across various genders and age groups. This diversity might contribute to a better understanding of BS clinical features and pave the way for future multi-center studies.

Hypertension in India: a gender-based study of prevalence and associated risk factors.

BACKGROUND: Hypertension, a major non-communicable disease, is responsible for a significant number of global deaths, including approximately 17.9 million yearly. The Global Burden of Disease 2019 (GBD 2019) estimates that 19% of global deaths are attributed to elevated blood pressure. India, with a population of over 1.4 billion, is facing a serious challenge in combating this silent killer. This study aims to analyze the gender-based prevalence of hypertension in India and explore its associated risk factors using data from the fifth National Family Health Survey (NFHS-5). METHODS: NFHS-5 collected data from 636,699 households across all states and union territories. The study includes standardized blood pressure measurements for 17,08,241 individuals aged 15 and above. The data were analyzed using Stata, employing descriptive statistics for the assessment of the prevalence and binary logistic regression to identify predictors of hypertension. RESULTS: The study found the overall prevalence of hypertension in India to be 22.6%, with men (24.1%) having a higher prevalence than women (21.2%). Prevalence increased with age, reaching 48.4% in individuals aged 60 and above. Urban residents had a slightly higher prevalence (25%) than rural residents (21.4%), indicating the rapid spread of hypertension across all populations. Regional variations were observed, with the highest prevalence in Sikkim (37.9%) and the lowest in Rajasthan (16.5%). Increasing age, urban residence, belonging to certain religions (Muslim and other than Hindu or Muslim), and being classified as Scheduled Tribes (ST) were associated with a higher likelihood of hypertension. Conversely, belonging to Scheduled Castes (SC) or Other Backward Classes (OBC), being currently unmarried, and having higher education were associated with a lower likelihood of hypertension. Wealth index analysis revealed that those in the richest quintile were more likely to have hypertension. Behavioural risk factors, such as alcohol consumption, overweight, obesity, increased waist circumference, and high blood glucose levels, are positively associated with hypertension. CONCLUSION: Hypertension is a significant health burden in India, affecting both men and women. Age is the strongest non-modifiable predictor for both men and women. However, ageing women have higher odds of hypertension than ageing men, and this distinction becomes much more evident in their older ages. Obese women, based on BMI, have higher odds of hypertension than men. However, hypertension prevalence is slightly higher among men who are overweight or obese compared to women. BMI, waist circumference, random glucose level, alcohol use, and education level emerged as major predictors. Health education and awareness campaigns are critical to control the growing burden of hypertension in India. Policymakers must focus on preventive measures, targeting lifestyle changes and improved healthcare access for both men and women. By addressing these risk factors, India can make significant progress in controlling hypertension and reducing its impact on public health.

Prevalence of depressive symptoms among young adults in Brazil: Results of the 2013 and 2019 editions of the National Health Survey.

OBJECTIVE: To estimate the prevalence of depressive symptoms in the population aged 18 to 24, according to socioeconomic and demographic aspects in Brazil, comparing its evolution between 2013 and 2019. METHODS: Cross-sectional study carried out with secondary data obtained from National Health Survey 2013 and 2019. It were included 7,823 young adulthood (aged 18 to 24) from 2013 and 8,047 from 2019. The instrument used to assess depression was the Patient Health Questionnaire-9 (PHQ-9). All estimates included population weights and complex sampling. RESULTS: The prevalence of depression almost doubled: 10.9% (95%CI 9.6-12.2) in 2019, compared to 5.6% (95%CI 4.8-6.4) in 2013, an absolute difference of 5.3% (4.5-6.0) greater. Women were the most affected in both surveys, with an increase between 2013 (8.3%; 95%CI 6.9-9.6) and 2019 (15.6%; 95%CI 13.5-17.6) higher than that of men (2013: 2.9%; 95%CI 2.0-3.8 and 2019: 6.2%; 95%CI 4.7-7.7). In both sexes, the pattern of increase was greater for the groups aged 18 to 20, not participating in religious activities, who were at the lowest levels of education and income, who lived with two or three or more people, who lived in the Northeast, Southeast, capitals and metropolitan areas of the country. CONCLUSION: There was a significant increase in the prevalence of depressive symptoms over the six years between the two surveys. However, this increase did not occur homogeneously among the characteristics analyzed, indicating population groups and locations in Brazil where the presence of these symptoms increased most in the period.

The Impact of Severe Heart Disease on Causes of Death and Survival after Disability Retirement. / O Impacto da Cardiopatia Grave nas Causas de Óbito e Sobrevida após Aposentadoria por Invalidez.

BACKGROUND: Noncommunicable diseases contribute to premature deaths and limitations. Disability retirement is linked to chronic conditions, particularly cardiovascular diseases. The II Brazilian Guideline for Severe Heart Disease established criteria for cardiovascular disease classification. However, there is a lack of research in this topic within federal institutions. OBJECTIVES: Evaluate the survival and causes of death among disabled retirees at UFRJ, focusing on the impact of severe heart disease. METHODS: A retrospective cohort study based on retirement and death records over 15 years. Retirements were categorized into three groups: full retirement due to severe heart disease, full retirement due to other diseases and proportional. Causes of death were obtained from death certificates. Mortality rates, survival and the presence of matching diagnoses between retirement and death were evaluated. Chi-square, log-rank, Cox models, Kaplan-Meier curves were utilized. Statistical significance with a 95% confidence interval, considering p<0.05. RESULTS: There were 630 retirements, 368 (51.4%) in females, with an average age of 52.9 (SD=7.8) years, and 169 (26.8%) deaths. Mortality was higher in professors (37.0%; p=0.113), in the age group between 65 and 70 years (48.4%; p=0.004), in males (34.0%; p=0.001), and in full retirements due to severe heart disease (41.5%; p<0.001). Matching diagnoses between retirement and death were more frequent in professors (74.1%; p=0.026) and in full retirements due to severe heart disease (72.7%; p<0.001). CONCLUSIONS: Severe heart disease diagnosis is associated with higher mortality and shorter survival in disabled retirees. Its frequent occurrence in retirement and death diagnoses underscores its significance in this context.

FUNDAMENTO: As doenças não comunicáveis são responsáveis por mortes prematuras e limitações. A aposentadoria por invalidez está associada a condições crônicas, especialmente a doenças cardiovasculares. A II Diretriz Brasileira de Cardiopatia Grave definiu critérios para enquadramento das doenças cardiovasculares. Poucos estudos abordam esse tema em instituições federais. OBJETIVOS: Avaliar sobrevida e causas de óbito de servidores aposentados por invalidez na UFRJ, com ênfase no impacto da cardiopatia grave. MÉTODOS: Estudo de coorte retrospectivo baseado nos registros de aposentadorias e óbitos ao longo de 15 anos. As aposentadorias foram divididas em três grupos: integral por cardiopatia grave, integral por outras doenças e proporcional. As causas de óbito foram obtidas a partir das certidões de óbito. Foram avaliadas taxa de mortalidade, sobrevida e a presença de diagnósticos concordantes entre a aposentadoria e o óbito. Foram utilizados testes qui-quadrado, log-rank, modelos de Cox e curvas de Kaplan-Meier. Significância estatística com intervalo de confiança de 95%, considerando p < 0,05. RESULTADOS: Foram 630 aposentadorias, 368 (51,4%) no sexo feminino, com idade média de idade de 52,9 (DP=7,8) anos, e 169 (26,8%) óbitos. A mortalidade foi maior nos professores (37,0%; p=0,113), na faixa etária entre 65 e 70 anos (48,4%; p=0,004), no sexo masculino (34,0%; p=0,001), e nas aposentadorias integrais por cardiopatia grave (41,5%; p < 0,001). Diagnósticos concordantes entre aposentadoria e óbito foram mais frequentes em professores (74,1%; p=0,026) e nas aposentadorias integrais por cardiopatia grave (72,7%; p < 0,001). CONCLUSÕES: O diagnóstico de cardiopatia grave confere maior taxa de mortalidade e menor sobrevida aos aposentados por invalidez, e sua presença em maior frequência nos diagnósticos de aposentadoria e óbito ressalta sua importância neste contexto.

Lack of Anticoagulant Use in Patients with Atrial Fibrillation and Increased Risk of Thromboembolic Events According to Sex: Insights from a Multicentric Brazilian Study. / Falta de Uso de Anticoagulantes em Pacientes com Fibrilação Atrial e Risco Aumentado de Eventos Tromboembólicos de Acordo com o Sexo: Insights de um Estudo Multicêntrico Brasileiro.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia, and its presentation differs according to age and sex. Recent studies have revealed differences in AF among various demographic groups, including the Latin American population. OBJECTIVES: To better understand potential disparities in AF prevalence and treatment strategies in the Brazilian population through data from a large multicentric prospective registry. METHODS: The Rede D'Or AF registry is a multicenter prospective observational study including patients aged ≥ 18 years with AF who were seen in the emergency department of 32 tertiary hospitals in Brazil. Patients were characterized according to sex and other baseline characteristics and were classified according to previous anticoagulant use. The lack of anticoagulant use in patients with previous indications was analyzed. Statistical significance was set at 5%. RESULTS: The study data were from a total of 1955 patients enrolled. Male sex was more prevalent, and men were younger than the women. Due to an increased prevalence of previous AF episode and a higher CHA2DS2-VASc score, more women had indications for anticoagulant therapy; however, a significant proportion was not receiving this treatment. From 29 in-hospital deaths, 15 patients had previous indication for anticoagulation, but only 3 were using anticoagulants. CONCLUSION: This study revealed sex-related differences in the Brazilian population of patients with AF that are consistent with trends in high-income countries. The promotion of better implementation of anticoagulant and antithrombotic therapies to reduce the risk of death and thromboembolic events among women with AF in Brazil is crucial.

FUNDAMENTO: A fibrilação atrial (FA) é a arritmia cardíaca mais prevalente e sua apresentação difere de acordo com a idade e o sexo. Estudos recentes revelaram diferenças na FA entre vários grupos demográficos, incluindo a população latino-americana. OBJETIVOS: Melhor compreender as possíveis disparidades na prevalência da FA e nas estratégias de tratamento na população brasileira por meio de dados de um registro prospectivo multicêntrico de grande escala. MÉTODOS: O registro de FA da Rede D'Or é um estudo observacional prospectivo multicêntrico que incluiu pacientes com idade ≥ 18 anos com FA atendidos no pronto-socorro de 32 hospitais terciários no Brasil. Os pacientes foram caracterizados de acordo com o sexo e outras características basais e classificados de acordo com o uso prévio de anticoagulantes. Foi analisada a falta de uso de anticoagulantes em pacientes com indicações prévias. A significância estatística foi estabelecida em 5%. RESULTADOS: Os dados do estudo foram provenientes de um total de 1.955 pacientes inscritos. O sexo masculino foi mais prevalente e os homens eram mais jovens que as mulheres. Devido ao aumento da prevalência de episódios anteriores de FA e a um escore CHA2DS2-VASc mais elevado, mais mulheres tiveram indicação de terapia anticoagulante; no entanto, uma proporção significativa não estava recebendo esse tratamento. Dos 29 óbitos intra-hospitalares, 15 pacientes tinham indicação prévia para anticoagulação, mas apenas 3 estavam em uso de anticoagulantes. CONCLUSÃO: O presente estudo revelou diferenças relacionadas ao sexo na população brasileira de pacientes com FA que são consistentes com tendências em países de alta renda. A promoção de uma melhor implementação de terapias anticoagulantes e antitrombóticas para reduzir o risco de óbito e eventos tromboembólicos entre mulheres com FA no Brasil é crucial.

Prevalence of myopic eyes in private practice and public care services in Brazil: 11 years of retrospective analysis.

PURPOSE: This study aimed to examine the prevalence of myopic eyes over 11 years (2008-2018) in a private clinic and a public assistance service. METHODS: We retrospectively evaluated 6332 individuals (12,664 eyes) between 5 and 25 years old, seen at a private clinic-CEMO (2,663 individuals) and a public service-HOIP (3,669 individuals) from 2008 to 2018. We evaluated the prevalence of myopic eyes (EE ≤-0.50) and high myopic eyes (EE ≤-6.00). RESULTS: Sex and services did not show statistical differences. The variation in the prevalence of myopic and high myopic eyes showed a random pattern during the study period (this prevalence could not be increased). Prevalences ranged from 20.7% (in 2017) to 32.4% (in 2015) for myopic eyes and from 1.6% (in 2009 and 2016) to 3.3% (in 2015) for eyes with high myopia. The prevalence of myopia showed a statistically significant increase based on the age group. CONCLUSION: The prevalence of myopic eyes did not increase in our study. The mean prevalence of myopic eyes was similar in the private clinic and public service.

Retinoblastoma in Ceara: An epidemiological study in a Brazilian pediatric oncology referral center.

PURPOSE: Although Brazil has a high prevalence of retinoblastoma, there is a lack of epidemiological data on the disease. Thus, in this study, we aimed to evaluate the epidemiological profile of patients diagnosed with retinoblastoma in the ophthalmology department of a pediatric tertiary referral hospital in Ceara, Brazil. METHODS: A descriptive and cross-sectional study was conducted by retrospectively analyzing the clinical and socioeconomic data from the medical records of pediatric patients followed-up at the hospital between 2007 and 2021. Retinoblastoma was diagnosed on the basis of a fundoscopic or histopathologic examination. RESULTS: The data of 105 patients were included in the study, and the mean patient age at the time of diagnosis was 1.7 years. Most of the patients were women (50.5%) and hailed from rural areas (57.4%), which was associated with a higher tumor stage. Of the 150 patients, 57.1% initially presented with leukocoria. Ocular hyperemia was associated with more advanced stages of retinoblastoma (p=0.004). Bilateral involvement was observed in 25.7% of the patients and at a significantly younger age (p=0.009). The presence of retinal detachment, vascularized lesions, and vitreous seeds significantly increased the likelihood of requiring enucleation. DISCUSSION: This study presents an epidemiological description of retinoblastoma in Brazil, which highlights the significance of early detection. Delayed diagnosis is associated with a poorer visual prognosis and higher mortality rate, particularly in patients with unilateral disease. Risk factors for a more severe disease were retinal detachment, vascularized lesions, and vitreous seeds. The correlation between histopathological features and clinical outcomes was limited. CONCLUSION: Further studies are required to assess the influence of ocular hyperemia, fundoscopic assessment, and histopathologic findings on the prognosis of retinoblastoma. Moreover, it is critical to devise interventions to reduce the time-to-diagnosis in rural areas.

Temporal trend and epidemiological profile of accidents caused by venomous animals in the state of Pará, 2018-2022.

Accidents involving venomous animals are a significant public health issue in Brazil, with about 140,000 cases reported annually. Pará, with its vast forests and biodiversity, experiences high incidences exacerbated by human-environment interactions. This study analyzes the temporal trend and epidemiological profile of such accidents in Pará from 2018 to 2022. A cross-sectional study using SINAN data, employing Prais-Winsten linear regression to evaluate temporal trends. Incidences were stratified by sex, age group, and accident location (rural, agricultural, work, residential, leisure). From 2018 to 2022, accidents in rural areas, particularly agricultural, increased notably, with a 40% rise overall. Males aged 20-39 years were most affected. March consistently recorded the highest cases, indicating a seasonal peak. Accidents involving venomous animals in Pará are increasing, particularly in areas of agricultural expansion. This trend highlights the need for intensified prevention efforts, public education, and effective treatment strategies, integrating public health measures and environmental management.

Unintentional fall mortality by place, sex, and age group among older Chinese adults, 2010-21.

Background: Unintentional falls are known to be a leading cause of injury mortality among older Chinese adults, yet we lack data on the most recent trends in related mortality. To address this, we used the latest nationally representative data from China to examine trends in elderly unintentional fall mortality by place (urban/rural), sex (men/women), and age group (65-69, 70-74, 75-79, 80-84, and ≥85 years) from 2010 to 2021. Methods: We retrieved mortality data from the Chinese Health Statistical Yearbook (2010-21) and population data from the Chinese Population Census (2010, 2020). Using line graphs, we examined mortality trends over time. We fitted a joinpoint regression model to detect periods experiencing significant changes and calculated the average and specific annual percentage change of mortality rates to quantify significant changes in the mortality of the elderly due to unintentional falls. Results: Between 2010 and 2021, the age-standardised mortality rate from unintentional falls increased from 45.7 to 67.8 per 100 000 population among Chinese adults aged 65 years and older. Subgroup analyses by sex and place showed similar changing patterns to the overall mortality trends. The joinpoint regression identified certain recent periods that saw significant increases in mortality among adults aged 65-69, 70-74, 75-79, and 80-84 years. During the study period, men and individuals living in rural areas generally had higher unintentional fall mortality rates than women and people living in urban areas (mortality rate ratios: 1.09-1.21 for men vs. women and 1.01-1.27 for rural areas vs. urban areas). Notably, the differences between urban and rural areas, and those between men and women, were consistent across the three younger age groups (65-69, 70-74, and 75-79 years) studied, but reduced in the two oldest age groups (80-84 and ≥85 years). Conclusions: The age-standardised mortality rate from unintentional falls increased between 2010 and 2021 among Chinese adults aged 65 years or older, with wide variations across years. Unintentional fall mortality has recently increased among adults aged 65 to 84 years. Differences between urban and rural areas, as well as between men and women, deserve the attention of injury researchers and policymakers.

Adult Day Services Center Participant Characteristics: United States, 2022.

Introduction: This report contains the most recent national estimates of selected characteristics of adult day services center participants. Methods: Data are from the adult day services center component of the 2022 wave of the biennial National Post-acute and Long-term Care Study. Data analyses excluded missing data, incorporated complex survey weights, and were performed using Stata/SE version 17.0. Key findings: In 2022, 58% of adult day services center participants were female, 40% were White non-Hispanic, and 32% were younger than age 65. Most participants were Medicaid users. About 61% of participants needed assistance with three to six activities of daily living and had two or more chronic conditions.

Smoking prevalence among adults in China Mainland and their age of smoking initiation during adolescence: a national cross-sectional study.

OBJECTIVES: This study aims to calculate the national prevalence of smoking among Chinese adults and to describe the hazard of smoking initiation by age during their adolescence, as well as the disparities in sex, residence and age groups. DESIGN: A cross-sectional study. SETTING: The data were derived from a multistage sampling study conducted in 120 cities in China Mainland. PARTICIPANTS: A total of 9963 participants aged ≥19 years were included. PRIMARY OUTCOME MEASURES: Survival analysis was used to quantify the hazards of smoking initiation by a single year of age during adolescence, and the log-rank test was used to compare the hazard curves across subgroups. RESULTS: The prevalence of current smoking among males and females was 27.7% and 2.0%, respectively, and 56.2% of current smokers began smoking at or before the age of 18. The hazard of smoking initiation during adolescence for females was less than 0.5%, and the hazard for males increased gradually before 14 years of age and increased sharply at age 15 (4.34%), then peaked at age 18 (6.24%). Males in rural experienced a higher hazard of smoking initiation than those in urban (χ2=5.35, p=0.02) and no such difference was found in females. By the age of 18 years, 11.7% of participants (1.8% for females and 23.4% for males) had ever smoked. CONCLUSIONS: The prevalence of smoking among Chinese adults was lower than once reported. Males experienced higher hazards of smoking initiation at all ages than females. The hazard pattern suggests that the key focus for smoking prevention are males and adolescents aged 15-18 years, and future interventions should be delivered to the right target population at the appropriate time.

[Analysis of serious trauma injury patterns in Navarre (Spain) (2010-2019)].

BACKGROUND: The aim of this study is to describe major trauma cases in Navarre and analyze differences based on mortality groups, sex, and mode of injury. METHODS: Cross-sectional study of major traumas (severity =3) registered in Navarre between 2010 and 2019. We analyzed the type of trauma, intentionality, the mode of injury, and the affected anatomical area. The odds ratio for major trauma associated with different variables was calculated. RESULTS: The study included 2,609 patients; mean age was 54.7 years (0-101) and 70.9% were male. A predominance of accidental (84%) / blunt (94.7%) major traumas was recorded, primarily resulting from falls (46.5%) and car accidents (18.4%). Women experienced more falls and pedestrian accidents, while men had more motorcycle, bicycle, knife/firearm accidents, and contusions. Most major traumas affected the head and thorax. Head trauma was significantly more common in deceased individuals and women, while thoracic trauma was more frequent in patients who died on-site and in men. Head injuries were caused by falls from low heights and firearms, whereas thoracic injuries resulted from car accidents and falls from height. The risk of major trauma decreased with age; deceased patients were between two and three times more likely to present lesions in all anatomical areas. CONCLUSIONS: Gender differences are observed in intentionality, type, and mode of injury. Head and thoracic injuries are potentially life-threatening and abdominal and extremity/pelvic ring injuries are associated with early deaths. This suggests that the extent and severity of these injuries complicate treatment and management.

Prevalence of current smoking and associated factors in older adults in Brazil.

OBJECTIVE: The aim of this study was to estimate the prevalence of current smoking and its associated factors in adults aged 50 years and older in Brazil. METHODS: This cross-sectional study utilized data from the ELSI-Brazil study, encompassing 9,412 adults aged 50 years or over. A multivariate model using Poisson regression with a robust estimator was employed, estimating prevalence ratios and their 95% confidence intervals. RESULTS: The prevalence of current smoking was 17.04%. It was positively and independently associated with male gender, age up to 62 years, living without a partner, illiteracy, chronic obstructive pulmonary disease, depression, poor or very poor sleep quality, and alcohol intake more than once a month. Conversely, systemic arterial hypertension, hypercholesterolemia, diabetes mellitus, and repetitive strain injuries showed an inverse and independent association with current smoking. CONCLUSION: The prevalence of current smoking among adults over 50 years old in Brazil was approximately 17%, with associations found with certain sociodemographic conditions and self-reported comorbidities.

Interacting trends of colorectal cancer incidence: the combined effects of screening and birth cohort.

BACKGROUND: Colorectal cancer remains a major global public health challenge. Its incidence is shaped by a complex interplay of screening programmes and age, period and cohort factors. METHODS: We introduce a novel Age-Period-Cohort-Screening (APCS) model to analyse trends in colorectal cancer incidence in Taiwan from 2000 to 2019. RESULTS: In 2010, the incidence of colorectal cancer in Taiwan increased by 19.2% (95% CI: 13.5%, 25.3%) for men and 15.6% (95% CI: 9.2%, 22.4%) for women. This was followed by annual declines of 3.4% (95% CI: 2.8%, 4.1%) and 3.1% (95% CI: 2.4%, 3.9%), respectively. By 2015 for men and 2014 for women, the age-standardized incidence had fallen below the levels projected in a no-screening scenario. By 2019, the incidence had further declined by 12.4% (95% CI: 11.8%, 13.1%) for men and 11.6% (95% CI: 10.7%, 12.6%) for women, compared with the no-screening scenario. Cohort effects have shown a persistent rise from 1920 to 1980: incidence increased 5.8-fold for men and 3.1-fold for women. The trend began to plateau after 1980, with a noticeable decline in women. CONCLUSION: Through its screening programme, Taiwan has successfully reduced colorectal cancer incidence by 10% as of 2019. Furthermore, the incidence due to cohort effects has plateaued and even begun to decline. However, continued monitoring remains crucial. The advanced APCS model could serve as a robust analytical tool for other researchers and policy makers evaluating the impacts of cancer screening programmes on incidence trends.

Prevalence of fractures in adults over 50 years of age with osteoporosis in Colombia.

What are the fractures associated with osteoporosis in Colombian persons over 50 years of age? Through the analysis of the Ministry of Health databases, Colombians over 50 years of age with osteoporosis fracture the forearm the most, followed by the thoracolumbar vertebrae and then the hip. We describe the differences between men and women. PURPOSE: The aim of this study was to determine the frequency of all bone fractures among adults aged 50 and above, both with and without osteoporosis, using data from SISPRO (Integrated Information System for Social Protection), the administrative database of the Colombian Ministry of Health. METHODS: Information was collected for the years 2017 to 2021 for all bone fractures (except cranial or face fractures), and how many of them occurred in patients who had the diagnosis of osteoporosis. Prevalence ratios (PR) were estimated separately for males and females by dividing the prevalence in those with by the prevalence of those without osteoporosis. RESULTS: For the period from 2017 to 2021, 303,037 adults over 50 years of age (females 279,057, 92.1%) were diagnosed with osteoporosis in Colombia, for a prevalence of 39.4 per thousand women and 4.14 in men; 40,823 of these women (14.6%) presented a fracture in the period, as well as 4020 of men (16.7%). Osteoporosis was present in 7.5% of the 596.618 (females 369.795; 62.0%) who suffered any fracture (1.8% of males and 11.0% of females). Overall PR was 3.4 (males 4.3; females 3.3). In men with osteoporosis, the most frequent fractures were hip (902), followed by lumbar vertebrae (842), ribs (648), and forearm (538), while in women, forearm (11,001), followed by hip (6885), lumbar vertebra (4813), and thoracic vertebra (2701) were the most common. PR in men was 21.9 for dorsal vertebrae fracture, 21.3 for lumbar vertebrae, 11.8 for ribs, and 7.7 for hip fracture. In women, PR was 15.7 for thoracic vertebrae, 13.3 for lumbar vertebrae, 3.3 for hip fracture, and 2.2 for forearm fracture. CONCLUSION: Osteoporosis is a highly prevalent disease in Colombia where women are more affected. Although fractures were more common in women, men with osteoporosis have a higher PR of associated fractures.

Suicide in China: The Trends and Differentials From 2002 to 2021.

OBJECTIVE: The objective of this study was to provide an updated analysis of suicide characteristics in China from 2002 to 2021, with the aim of informing the development of evidence-based suicide prevention strategies. METHODS: The Ministry of Health-Vital Registration System (MOH-VR) provided the data on suicide mortality, which enabled us to examine the average annual percentage change (AAPC) in suicide rates using a Poisson regression model. RESULTS: Notably, there has been a significant decline in suicide rates observed in both urban and rural areas. In the early years of the study period, higher suicide rates were observed among females compared to males; however, a shift occurred after 2005, with male suicide rates surpassing those of females. Except for 2005, rural areas consistently exhibited higher suicide rates than urban areas. Furthermore, suicide rates exhibited an increasing trend with age, irrespective of gender or region. CONCLUSION: These findings highlight a decreasing trend in suicide rates in China over the past two decades, although gender and regional disparities persist. Going forward, sustained efforts in suicide prevention, with a specific focus on mental health, are warranted.

Prevalence of Certain Corneal Conditions and their Demographic Risk Factors; Tehran Geriatric Eye Study.

BACKGROUND: Corneal abnormalities are one of the important reasons for visual impairment. There is little evidence of the prevalence of different types of corneal abnormalities. The aim of this study was to assess the prevalence of various corneal abnormalities and identify the key risk factors associated with these abnormalities in an elderly population residing in Tehran. METHODS: The Tehran Geriatric Eye Study (TGES) was conducted as a cross-sectional study, utilizing a population-based approach and employing stratified cluster random sampling. The study focused on individuals aged 60 years and above residing in Tehran. An ophthalmologist performed a slit lamp examination to evaluate the eyelid, cornea, and crystalline lens. RESULTS: The prevalence of posterior embryotoxon (PE), punctate epithelial defect (PED), pigment on endothelium (POE), corneal dystrophy (CDys), corneal vascularization (CV), and corneal degeneration (CDeg) were estimated to be 0.08% (95% confidence interval [CI]: 0.02 to 0.40), 8.77% (95% CI: 6.64 to 11.51), 0.57% (95% CI: 0.33 to 0.98), 0.53% (95% CI: 0.33 to 0.82), 0.95% (95% CI: 0.60 to 1.52), and 44.87% (95% CI: 41.80 to 47.98), respectively. Overall, approximately 49.08% of the participants exhibited some form of corneal abnormality in at least one eye. The multiple logistic regression model revealed that increasing age was significantly associated with PED, CV, and CD. Furthermore, illiterate participants had a significantly higher prevalence of PE. CONCLUSION: The findings of this study indicate that approximately half of the elderly population aged 60 years and above in Tehran have at least one corneal abnormality, with corneal degeneration being the most prevalent. Age was identified as the primary determinant of corneal abnormalities.

Changes in the incidence of melanoma in Australia, 2006-2021, by age group and ancestry: a modelling study.

OBJECTIVES: To estimate the incidence of melanoma in Australia among people with ancestries associated with low, moderate, or high risk of melanoma, by sex and 5-year age group; to establish whether age-specific incidence rates by ancestry risk group have changed over time. STUDY DESIGN: Modelling study; United States (SEER database) melanoma incidence rates for representative ancestral populations and Australian census data (2006, 2011, 2016, 2021) used to estimate Australian melanoma incidence rates by ancestry-based risk. SETTING, PARTICIPANTS: Australia, 2006-2021. MAIN OUTCOME MEASURES: Age-specific invasive melanoma incidence rates, and average annual percentage change (AAPC) in age-specific melanoma rates, by ancestry-based risk group, sex, and 5-year age group. RESULTS: The proportion of people in Australia who reported high risk (European) ancestry declined from 85.3% in 2006 to 71.1% in 2021. The estimated age-standardised melanoma incidence rate was higher for people with high risk ancestry (2021: males, 82.2 [95% confidence interval {CI}, 80.5-83.8] cases per 100 000 population; females, 58.5 [95% CI, 57.0-59.9] cases per 100 000 population) than for all Australians (males, 67.8 [95% CI, 66.5-69.2] cases per 100 000 population; females, 45.4 [95% CI, 44.3-46.5] cases per 100 000 population). AAPCs were consistently positive for Australians aged 50 years or older, both overall and for people with high risk ancestry, but were statistically significant only for some age groups beyond 65 years. AAPCs were negative for people aged 34 years or younger, but were generally not statistically significant. CONCLUSIONS: Melanoma incidence has declined in some younger age groups in Australia, including among people with high risk ancestry. Social and behavioural changes over the same period that lead to lower levels of ultraviolet radiation exposure probably contributed to these changes.
