Mental health in persons with von Willebrand disease in the United States - a large national database study.

BACKGROUND: There are very few large population-based studies studying mental health in persons with von Willebrand disease (PwVWD). OBJECTIVES: We aim to assess prevalence of depression and anxiety in PwVWD over a period of 20 years and identify bleeding symptoms that may be more likely associated with depression and anxiety in PwVWD. METHODS: This is a retrospective cohort study using a deidentified national dataset from 1118 hospitals with 176 million patients. Cases were defined as patients aged 0-110 years, both male and female, with von Willebrand disease (VWD), without hemophilia. Controls were defined as patients aged 0-110 years, both male and female, without VWD or hemophilia. We compared rates of depression and anxiety in cases and controls and by type of bleeding symptoms. RESULTS: We identified 66 367 PwVWD and 183 890 766 controls. The prevalence of depression (23.12% vs 8.62%; p ≤ .00093; relative risk = 2.68) and anxiety (32.90% vs 12.29%; p ≤ .00093; relative risk = 2.68) was higher in PwVWD. Most of the bleeding symptoms were associated with higher rates of depression and anxiety in PwVWD with the highest rates with abnormal uterine bleeding, hematemesis, hemoptysis, hematuria, and melena. CONCLUSION: Our study shows that mental health disorders in PwVWD are a significant health burden, and that burden is increased with documented bleeding symptoms. It is important that primary care physicians and hematologists caring for this population recognize this increased risk and appropriately screen and refer to mental health professionals.

Self-rated health in old age, related factors and survival: A 20-Year longitudinal study within the Silver-MONICA cohort.

INTRODUCTION: Self-rated health (SRH) offers insights into the evolving health demographics of an ageing population. AIM: To assess change in SRH from old age to very old age and their associations with health and well-being factors, and to investigate the association between SRH and survival. METHODS: All participants in the MONICA 1999 re-examination born before 1940 (n = 1595) were included in the Silver-MONICA baseline cohort. The Silver-MONICA follow-up started in 2016 included participants in the Silver-MONICA baseline cohort aged 80 years or older. Data on SRH was available for 1561 participants at baseline with 446 of them also participating in the follow-up. The follow-up examination included a wide variety of measurements and tests. FINDINGS: Most participants rated their health as "Quite good" (54.5 %) at baseline. Over the study period, 42.6 % had stable SRH, 40.6 % had declined, and 16.8 % had improved. Changes in SRH were at follow-up significantly associated with age, pain, nutrition, cognition, walking aid use, self-paced gait speed, lower extremity strength, independence in activities of daily living, weekly physical exercise, outdoor activity, participation in organized activities, visiting others, morale, and depressive symptoms. SRH at baseline was significantly associated with survival (p < 0.05). CONCLUSION: This study demonstrates associations between changes in SRH and a multitude of health- and wellbeing-related factors, as well as a relation between survival and SRH, accentuating their relevance within the ageing population.

Developing a national surveillance system for stroke and acute myocardial infarction using claims data in the Republic of Korea: a retrospective study.

BACKGROUND: Limited information is available concerning the epidemiology of stroke and acute myocardial infarction (AMI) in the Republic of Korea. This study aimed to develop a national surveillance system to monitor the incidence of stroke and AMI using national claims data. METHODS: We developed and validated identification algorithms for stroke and AMI using claims data. This validation involved a 2-stage stratified sampling method with a review of medical records for sampled cases. The weighted positive predictive value (PPV) and negative predictive value (NPV) were calculated based on the sampling structure and the corresponding sampling rates. Incident cases and the incidence rates of stroke and AMI in the Republic of Korea were estimated by applying the algorithms and weighted PPV and NPV to the 2018 National Health Insurance Service claims data. RESULTS: In total, 2,200 cases (1,086 stroke cases and 1,114 AMI cases) were sampled from the 2018 claims database. The sensitivity and specificity of the algorithms were 94.3% and 88.6% for stroke and 97.9% and 90.1% for AMI, respectively. The estimated number of cases, including recurrent events, was 150,837 for stroke and 40,529 for AMI in 2018. The age- and sex-standardized incidence rate for stroke and AMI was 180.2 and 46.1 cases per 100,000 person-years, respectively, in 2018. CONCLUSION: This study demonstrates the feasibility of developing a national surveillance system based on claims data and identification algorithms for stroke and AMI to monitor their incidence rates.

Who smokes in Australia? Cross-sectional analysis of Australian Bureau of Statistics survey data, 2017-19.

OBJECTIVES: To assess the socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked in Australia. STUDY DESIGN: Cross-sectional analysis of Australian Bureau of Statistics (ABS) survey data. SETTING, PARTICIPANTS: Adult participants (16 370 people aged 18 years or older) in the ABS 2017-18 National Health Survey (NHS); adult participants in the ABS 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) (6423 people aged 18 years or older). MAIN OUTCOME MEASURES: Socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked, expressed as population-weighted proportions, overall and by Indigeneity. RESULTS: Among adult NHS respondents, an estimated 58.8% of people who smoked daily (95% confidence interval [CI], 56.2-61.4%) were men, 61.3% (95% CI, 58.7-63.9%) were 25-54 years old, 72.5% (95% CI, 70.0-74.8%) were born in Australia, and 65.4% (95% CI, 62.8-67.8%) lived in major cities and 54.3% (95% CI, 51.6-57.0%) in areas in the two socio-economically most disadvantaged quintiles; 75.9% (95% CI, 73.5-78.1%) reported good to excellent health, 73.0% (95% CI, 70.5-75.4%) reported low to moderate psychological distress, 69.0% of those aged 25-64 years (ie, of working age) had completed year 12 (high school), and 68.5% were currently employed. An estimated 2.57 million people smoke daily in Australia: 2.37 million non-Indigenous people (92%) and 195 700 Aboriginal or Torres Strait Islander people (8%). CONCLUSIONS: While smoking is more frequent among people living in socio-economically disadvantaged areas and in certain population sub-groups, this first quantitative national profile indicates that most people who smoke daily are in paid employment, are non-Indigenous, are in good physical and mental health, and have completed year 12. Improved comprehensive structural supply- and demand-based tobacco control, informed by the needs of priority groups and the overall profile of people who smoke, is needed to reduce daily smoking prevalence among adults to the 2030 targets of 5% or less for all Australians and 27% or less for Aboriginal and Torres Strait Islander people.

Bronchiectasis among Indigenous adults in the Top End of the Northern Territory, 2011-2020: a retrospective cohort study.

OBJECTIVES: To assess the prevalence of bronchiectasis among Aboriginal and Torres Strait Islander (Indigenous) adults in the Top End of the Northern Territory, and mortality among Indigenous adults with bronchiectasis. STUDY DESIGN: Retrospective cohort study. SETTING, PARTICIPANTS: Aboriginal and Torres Strait Islander adults (18 years or older) living in the Top End Health Service region of the NT in whom bronchiectasis was confirmed by chest computed tomography (CT) during 1 January 2011 - 31 December 2020. MAIN OUTCOME MEASURES: Prevalence of bronchiectasis, and all-cause mortality among Indigenous adults with CT-confirmed bronchiectasis - overall, by sex, and by health district - based on 2011 population numbers (census data). RESULTS: A total of 23 722 Indigenous adults lived in the Top End Health Service region in 2011; during 2011-2020, 459 people received chest CT-confirmed diagnoses of bronchiectasis. Their median age was 47.5 years (interquartile range [IQR], 39.9-56.8 years), 254 were women (55.3%), and 425 lived in areas classified as remote (93.0%). The estimated prevalence of bronchiectasis was 19.4 per 1000 residents (20.6 per 1000 women; 18.0 per 1000 men). The age-adjusted prevalence of bronchiectasis was 5.0 (95% CI, 1.4-8.5) cases per 1000 people in the Darwin Urban health area, and 18-36 cases per 1000 people in the three non-urban health areas. By 30 April 2023, 195 people with bronchiectasis had died (42.5%), at a median age of 60.3 years (IQR, 50.3-68.9 years). CONCLUSION: The prevalence of bronchiectasis burden among Indigenous adults in the Top End of the NT is high, but differed by health district, as is all-cause mortality among adults with bronchiectasis. The socio-demographic and other factors that contribute to the high prevalence of bronchiectasis among Indigenous Australians should be investigated so that interventions for reducing its burden can be developed.

The Effect of Limb Salvage Efforts in Different Age Groups: Relationships Between Major and Minor Amputations.

"Limb salvage" efforts, such as performing minor amputations before infections spread proximally from the foot to decrease major lower extremity amputation, are an important part of healthcare today. It is unclear whether these efforts are preventing the number of major amputations and improving patients' quality of life and the cost-effectiveness of the U.S. healthcare system. Rates of non-traumatic lower extremity amputation (NLEA) among patients with diabetes decreased in the early 2000s but rebounded in the 2010s. We analyzed the proportion of major amputations and differences in amputation rates between age groups in Texas. Patient data was extracted from the Texas Hospital Discharge Data Public Use Data File. Population estimates were obtained from the Texas Population Estimates Program from 2011 to 2015 and from intercensal estimates provided by the U.S. Census Bureau from 2006 to 2010. Raw numbers of minor, major, and all NLEA surgeries and the ratio of major amputations to total amputations per year were reported for each age group. Poisson regression and Joinpoint analyses were performed to capture these changes in trends. Rates of amputations increased, with significant decreasing relative prevalence of major amputations. Patients aged 45 to 64 with diabetes are likely driving these increases. Rates of lower extremity amputation in patients with diabetes increased from 2009 to 2015. This holds for all and minor amputations. In contrast, the ratio of major to all amputations decreased from 2010. Utilization of major and minor amputation differs between age groups, remaining stable in the youngest subjects, with minor amputation rates increasing in those aged 45 to 64.

Risk perception and surveillance uptake in individuals at increased risk for pancreatic ductal adenocarcinoma.

BACKGROUND: Surveillance for pancreatic ductal adenocarcinoma (PDAC) is recommended for high-risk individuals with genetic variants in PDAC-associated genes and/or family history. Surveillance uptake and adherence may depend on the perception of PDAC risk and cancer worry. We aimed to determine PDAC risk perception in at-risk individuals and assess factors associated with PDAC surveillance uptake. METHODS: At-risk individuals identified from a prospective academic registry were sent a survey electronically. PDAC risk perception, cancer worry and surveillance uptake were surveyed. Factors associated with increased risk perception and surveillance were assessed. Five-year PDAC risk was calculated using the PancPRO risk assessment model, and correlation with subjective risk assessment was assessed. RESULTS: The overall survey response rate was 34% (279/816). The median perceived PDAC risk was twofold (IQR 1-4) above respondents' estimates of general population risk. Factors significantly associated with higher perceived PDAC risk included non-Hispanic white race, post-graduate education level, PDAC-affected first-degree relative, genetic variants and lack of personal cancer history. Cancer worry had a very weak correlation across PDAC risk estimates (r=0.16). No correlation between perceived PDAC risk and 5-year calculated PDAC risk was found. Older age, having a first-degree relative with PDAC, meeting with a medical provider about PDAC cancer risk and awareness of surveillance modalities were significant predictors of undergoing PDAC surveillance. CONCLUSIONS: Individuals at risk for PDAC do not report risk perception that correlates with calculated risk. This presents an opportunity for counselling of at-risk patients to individualise management and improve surveillance uptake for eligible individuals.

Exacerbation rates in Japanese patients with obstructive lung disease: A subanalysis of the prospective, observational NOVELTY study.

BACKGROUND: Although clinical trials including asthma and COPD patients have revealed much about exacerbation frequencies, most studies are limited in that they recruited patients only with a clear diagnosis of one disease or the other, based on conventional diagnostic criteria, which may exclude many real-world patients with mixed symptoms. METHODS: NOVELTY is a global prospective observational study of patients with asthma and/or COPD from real-world practice. In this subanalysis, we compared patient characteristics of obstructive pulmonary diseases between the Japanese population (n = 820) and the overall population excluding Japanese patients (n = 10,406). RESULTS: The Japanese population had fewer exacerbations than the overall population across most of the physician-assessed disease severities and all diagnoses. The difference in exacerbation frequencies was more prominent in patients with COPD and asthma + COPD. The Japanese population was older, had higher former smoking rates, lower BMI, fewer respiratory symptoms, and better health-related quality of life compared with the overall population across all diagnoses. CONCLUSIONS: We clarified differences in patient characteristics among patients with asthma and/or COPD in Japan compared with non-Japanese patients. Importantly, we found that Japanese patients with asthma and/or COPD had significantly fewer exacerbations compared with patients overall. The results from our study may contribute to the development of precision medicine and guidelines specific to Japan.

The impact of population characteristics on transportation CO2 emissions-does population aging important?

Reducing transportation CO2 emissions and addressing population characteristic changes are two major challenges facing China, involving various requirements for sustainable economic development. Due to the interdependence of population characteristics and transportation, human activities have become a significant cause of the increase in greenhouse gas levels. Previous studies mainly focused on evaluating the relationship between one-dimensional or multi-dimensional demographic factors and CO2 emissions, while few studies have reported on the effect of multi-dimensional demographic factors on CO2 emissions in transportation. Analyzing the relationship between transportation CO2 emissions is the foundation and key to understanding and reducing overall CO2 emissions. Therefore, this paper used the STIRPAT model and panel data from 2000 to 2019 to investigate the effect of population characteristics on CO2 emissions of China's transportation sector, and further analyzed the effect mechanism and emission effect of population aging on transportation CO2 emissions. The results show that (1) population aging and population quality restrained CO2 emissions from transportation, but the negative effects of population aging were indirectly caused by economic growth and transportation demand. And with the aggravation of population aging, the influence on transport CO2 emissions changed and presented a U-shape. (2) Population living standard on transportation CO2 emissions exhibited an urban-rural difference, and urban living standard was predominant in transportation CO2 emissions. Additionally, population growth is under a weakly positive effect on transportation CO2 emissions. (3) At the regional level, the effect of population aging on transportation CO2 emissions showed regional differences. In the eastern region, the CO2 emission coefficient of transportation was 0.0378, but not significant. In central and western regions, the influence coefficient of transportation was 0.6539 and 0.2760, respectively. These findings indicated that policy makers should make relevant recommendations from the perspective of coordinating population policy and energy conservation and emission reduction policy in transportation.

Prevalence and characteristics of co-occurrence of smoking and increasing-and-higher-risk drinking: A population survey in England.

BACKGROUND: Smoking and drinking alcohol both significantly contribute to mortality and morbidity, and there is a need to characterise the sociodemographic and health-related characteristics (e.g. mental distress) of people who do both in order to target resources. This study reports the prevalence and characteristics of adults in the general population in England who both drink alcohol at increasing-and-higher-risk levels and smoke. METHODS: We used cross-sectional data from a monthly, nationally representative survey of adults in England (n = 37,258; April 2020-March 2022). Weighted data were used to report prevalence and unweighted data were used to report descriptive statistics for sociodemographic and health-related characteristics. RESULTS: The prevalence of both smoking and increasing-and-higher-risk drinking was 4.6% (95% CI = 4.4-4.9; n = 1,574). They smoked a mean of 10.4 (SD = 8.86) cigarettes per day and had a mean AUDIT score of 12.8 (SD = 5.18). Nearly half (48.2%, n = 751) were trying to cut down on their smoking and 28.0% (n = 441) on their drinking. A quarter (25.3%, n = 397) had received General Practitioner advice on smoking while 8.7% (n = 76) had received advice on their drinking. Nearly half (48.6%, n = 745) reported experiencing psychological distress in the past month and 44.6% (n = 529) had a diagnosed mental health condition, both of which were higher than among all adults (28.1% and 29.1%, respectively). CONCLUSION: In England, from April 2020 to March 2022, the prevalence of both smoking and increasing-and-higher-risk drinking was 4.6%. This group appears to experience high rates of mental health problems and targeted support is needed.

Social Appearance Anxiety Scale: a psychometric investigation and evaluation of the influence of individual characteristics on social appearance anxiety in Brazilian adults who practice physical exercise.

Introduction: Evaluating signs of anxiety related to body appearance is becoming increasingly important in contemporary society and, in this sense, the Social Appearance Anxiety Scale (SAAS) seems an interesting alternative of measurement. Objectives: To evaluate the psychometric properties of the Portuguese version of the SAAS when applied to Brazilian adults who practice physical exercise and verify the influence of individual characteristics on participants' social appearance anxiety. Methods: This was a cross-sectional study conducted online. The participants completed the SAAS and a demographic questionnaire. The psychometric properties of the SAAS one-factor model were evaluated using confirmatory factor analysis. A structural model was built for men and women to verify the influence of individual characteristics of the participants on social appearance anxiety. Results: 1,495 individuals participated in the study (70.8% women; mean age = 29.5, SD = 8.9 years). The data obtained with the SAAS presented good indicators of validity and reliability for both genders (CFI > 0.97, TLI > 0.97, SRMR = 0.04, α > 0.97, ω > 0.85). For both men and women, greater levels of social appearance anxiety were observed among younger participants, who had a higher body mass index, self-reported an eating disorder, and perceived a change in their body after the onset of the COVID-19 pandemic. For women specifically, higher income and having started physical exercise more recently were associated with greater levels of social appearance anxiety. Conclusion: The findings supported the validity and reliability of the data obtained with the SAAS and revealed that when investigating social appearance anxiety in future research and clinical protocols, specific individual characteristics should be considered.

New Insights Into Refractory Chronic Cough and Unexplained Chronic Cough: A 6-Year Ambispective Cohort Study.

PURPOSE: Only limited studies have depicted the unique features and management of refractory chronic cough (RCC) and unexplained chronic cough (UCC). These led to the initiation of this study, which reported the demographic characteristics, manifestations, and long-term outcomes on a large series of consecutive RCC/UCC patients, providing a guideline-led real-world clinical experience. METHODS: Retrospective baseline information was obtained from Clinical Research Database (January 2016 to May 2021). At least 6 months after the last clinic visit, included subjects were prospectively followed up. RESULTS: Three hundred and sixty-nine RCC and UCC patients (199 females, 53.9%) were analyzed. The median cough duration was 24.0 (12.0-72.0) months. Laryngeal symptoms were reported in 95.9% of the patients. The common triggers for coughing were talking (74.9%), pungent odors (47.3%), eating (45.5%), and cold air (42.8%). RCC was considered in 38.2%, and the remainder of 228 patients had UCC, with an equal sex distribution (P = 0.66). Among the 141 RCCs, 90.8% (128) had refractory reflux cough, which was more responsive to current treatments (P < 0.01). Although most features and test results between RCC and UCC were similar, UCC was more commonly inappropriately treated (P < 0.01). Nineteen (7.7-41.1) months after the final clinic visit, 31.2% still coughed persistently, while 68.8% reported cough improvement or remission. RCC reported more favorable treatment outcomes (including cough improvement, control, and spontaneous remission) than UCC (P < 0.01). Coughs with long duration before the initial cough clinic visit (P < 0.01), frequent urinary incontinence (P < 0.01), and being sensitive to "talking" (P < 0.01) or "cold air" (P < 0.01) were less likely to be solved. CONCLUSIONS: The current treatments only improve cough symptoms in two-thirds of patients. Clinical indicators for treatment failure were those coughing for long duration and being sensitive to "talking" or "cold air."

Significant improvements in cataract treatment and persistent inequalities in access to cataract surgery among older Poles from 2009 to 2019: results of the PolSenior and PolSenior2 surveys.

Background and aims: Cataract is the leading cause of visual impairment and blindness among older adults worldwide, that can be corrected through surgical interventions. However, diagnosis and treatment bias can be observed, and it is a major issue for improving health policies. Therefore, we assessed a declared prevalence of cataract and the frequency of surgical treatment of this condition in the Polish population in the years 2009-2019. To provide evidence of health inequalities, we compared operated and non-operated seniors using selected socioeconomic factors and identified variables affecting the availability of cataract surgery services over a 10-year follow-up period. Methods: An analysis based on a survey among 4,905 participants of the nationwide PolSenior study conducted in 2008-2009, and 5,031 participants of PolSenior2 conducted one decade later to assess the health of Poles over 65 years of age. Results: Cataract diagnosis was declared by 25.5 and 28.2% of the study population in PolSenior and PolSenior2 surveys, respectively. Out of those diagnosed with cataract in PolSenior, 46.5% underwent surgical treatment for at least one eye. This rate increased up to 67.9% in the survey conducted 10 years later. Independent factors increasing the chance for cataract surgery in both cohorts included male sex and age > 75 years. Additional factors were self-reported good health status in PolSenior and lack of financial problems in purchasing medicines in PolSenior2. Over the investigated decade, the chances for cataract surgical treatment increased in single-living and widowed patients. The shortage of funds for medications remained the only significant barrier for surgery. Conclusion: Although the prevalence of cataract in the older adult population in Poland has not changed from 2009 to 2019, the rate of cataract surgeries has considerably increased over the analyzed decade. Patients with lower socioeconomic status and women have lower access to surgical cataract management.

Labor market affiliation of patients with myeloproliferative neoplasms: a population-based matched cohort study.

BACKGROUND: Patients with myeloproliferative neoplasms (MPNs) suffer from substantial symptoms and risk of debilitating complications, yet observational data on their labor market affiliation are scarce. MATERIAL AND METHODS: We conducted a descriptive cohort study using data from Danish nationwide registries, including patients diagnosed with MPN in 2010-2016. Each patient was matched with up to ten comparators without MPN on age, sex, level of education, and region of residence. We assessed pre- and post-diagnosis labor market affiliation, defined as working, unemployed, or receiving sickness benefit, disability pension, retirement pension, or other health-related benefits. Labor market affiliation was assessed weekly from two years pre-diagnosis until death, emigration, or 31 December 2018. For patients and comparators, we reported percentage point (pp) changes in labor market affiliation cross-sectionally from week -104 pre-diagnosis to week 104 post-diagnosis. RESULTS: The study included 3,342 patients with MPN and 32,737 comparators. From two years pre-diagnosis until two years post-diagnosis, a larger reduction in the proportion working was observed among patients than comparators (essential thrombocythemia: 10.2 [95% CI: 6.3-14.1] vs. 6.8 [95% CI: 5.5-8.0] pp; polycythemia vera: 9.6 [95% CI: 5.9-13.2] vs. 7.4 [95% CI: 6.2-8.7] pp; myelofibrosis: 8.1 [95% CI: 3.0-13.2] vs. 5.8 [95% CI: 4.2-7.5] pp; and unclassifiable MPN: 8.0 [95% CI: 3.0-13.0] vs. 7.4 [95% CI: 5.7-9.1] pp). Correspondingly, an increase in the proportion of patients receiving sickness benefits including other health-related benefits was evident around the time of diagnosis. CONCLUSION: Overall, we found that Danish patients with essential thrombocythemia, polycythemia vera, myelofibrosis, and unclassifiable MPN had slightly impaired labor market affiliation compared with a population of the same age and sex. From two years pre-diagnosis to two years post-diagnosis, we observed a larger reduction in the proportion of patients with MPN working and a greater proportion receiving sickness benefits compared with matched individuals.

Mortality and causes of death in patients with Parkinson's disease: a nationwide population-based cohort study.

Objective: Parkinson's disease (PD) is a neurodegenerative disease involving multiple systems that can affect mortality. This study aimed to compare all-cause and cause-specific mortality between people with PD and without PD. Methods: This population-based prospective cohort study is based on Korean National Health Insurance Service data. The primary outcome was the hazard ratio (HR) of all-cause and cause-specific mortality for PD from 2010 to 2019. Cox proportional hazards regression was applied to calculate HRs under crude and three adjusted models with epidemiologic variables. Results: A total of 8,220 PD patients and 41,100 age- and sex-matched controls without PD were registered. Ten-year mortality was 47.9% in PD patients and 20.3% in non-PD controls. The mortality rate was higher among older and male participants. The leading cause of death in PD was nervous system diseases (38.73%), and 97.1% of those were extrapyramidal and movement disorders, followed by circulatory diseases (15.33%), respiratory diseases (12.56%), and neoplasms (9.7%). PD contributed to an increased risk of all-cause death with an HR of 2.96 (95% CI = 2.84-3.08). HRs of death for PD were 3.07 (95% CI = 2.74-3.45) from respiratory diseases, 1.93 (95% CI = 1.75-2.13) from circulatory diseases, 2.35 (95% CI = 2.00-2.77) from external causes, and 2.69 (95% CI = 2.10-3.43) from infectious diseases. Conclusion: These results showed that PD was related to a higher risk of mortality in all ages and sexes. The leading causes of death in PD were nervous, circulatory, respiratory, infectious diseases, and external causes.

Melanoma literacy among the general population of three western US states.

Melanoma is a significant cause of cancer death, despite being detectable without specialized or invasive technologies. Understanding barriers to preventive behaviors such as skin self-examination (SSE) could help to define interventions for increasing the frequency of early detection. To determine melanoma knowledge and beliefs across three high-incidence US states, 15,000 surveys were sent to a population-representative sample. We aimed to assess (1) melanoma literacy (i.e., knowledge about melanoma risks, attitudes, and preventive behaviors) and (2) self-reported SSE and its association with melanoma literacy, self-efficacy, and belief in the benefits of SSE. Of 2326 respondents, only 21.2% provided responses indicating high knowledge of melanoma, and 62.8% reported performing an SSE at any time in their lives. Only 38.3% and 7.3% reported being "fairly" or "very" confident about doing SSE, respectively. SSE performance among respondents was most strongly associated with higher melanoma knowledge, higher self-efficacy, and personal history of melanoma. Melanoma literacy among survey respondents was modest, with greater literacy associated with a higher likelihood of reported preventive behavior. This assessment establishes a baseline and provides guidance for public health campaigns designed to increase prevention and early detection of this lethal cancer.

Characteristics of Adolescents Admitted with Acute Alcohol Intoxication: A Retrospective Multicentre Study in Antwerp, Belgium, in the Period 2015-2021.

Binge drinking among adolescents is common in Belgium, posing a risk of serious health consequences. Until today, only estimations of the prevalence of acute alcohol intoxication (AAI) in adolescents have been made. Research into potential risk factors has not yet been conducted in Belgium. Therefore, this study aims to gain more insight into the prevalence, medical characteristics and potential risk factors of AAI among adolescents. A retrospective multicentre chart study was performed on adolescents aged 10-17 years with AAI in Antwerp, Belgium (2015-2021). Patient's demographics, medical characteristics and information regarding the context of the AAI were collected from medical charts. Over the study period, a total of 1016 patients were admitted with AAI in Antwerp, having a median age of 16.6 years old, a median blood alcohol concentration of 1.95 g/L and combined drug use in 10% of cases. These findings did not significantly change over the study period. Multiple linear regression analysis indicated that after correcting for covariates, higher age, no combined drug use and decreased consciousness at admission were associated with more severe AAI cases (higher blood alcohol concentration). This study shows that AAI is prevalent among Belgian adolescents, and better targeted preventive measures and policies are needed. Our findings could be taken into account when developing preventive measures. However, data addressing the demographics and context of AAI were mostly missing. Therefore, prospective research is required to further investigate potential risk factors associated with AAI.

Hospital utilisation in Australia, 1993-2020, with a focus on use by people over 75 years of age: a review of AIHW data.

OBJECTIVES: To assess Australian hospital utilisation, 1993-2020, with a focus on use by people aged 75 years or more. DESIGN: Review of Australian Institute of Health and Welfare (AIHW) hospital utilisation data. SETTING, PARTICIPANTS: Tertiary data from all Australian public and private hospitals for the financial years 1993-94 to 2019-20. MAIN OUTCOME MEASURES: Numbers and population-based rates of hospital separations and bed utilisation (bed-days) (all and multiple day admissions) and mean hospital length of day (multiple day admissions), overall and by age group (under 65 years, 65-74 years, 75 years or more). RESULTS: Between 1993-94 and 2019-20, the Australian population grew by 44%; the number of people aged 75 years or more increased from 4.6% to 6.9% of the population. The annual number of hospital separations increased from 4.61 million to 11.33 million (146% increase); the annual hospital separation rate increased from 261 to 435 per 1000 people (66% increase), most markedly for people aged 75 years or more (from 745 to 1441 per 1000 people; 94% increase). Total bed utilisation increased from 21.0 million to 29.9 million bed-days (42% increase), but the bed utilisation rate did not change markedly (1993-94, 1192 bed-days per 1000 people; 2019-20, 1179 bed-days per 1000 people), primarily because the mean hospital length of stay for multiple day admissions declined from 6.6 days to 5.4 days; for people aged 75 years or more it declined from 12.2 to 7.1 days. However, declines in stay length have slowed markedly since 2017-18. Total bed utilisation was 16.8% lower than projected from 1993-94 rates, and was 37.3% lower for people aged 75 years or more. CONCLUSION: Hospital bed utilisation rates declined although admission rates increased during 1993-94 to 2019-20; the proportion of beds occupied by people aged 75 years or more increased slightly during this period. Containing hospital costs by limiting bed availability and reducing length of stay may no longer be a viable strategy.

Sexual Minority College Undergraduate Students Have Worse Health-Related Quality of Life, Diet Quality, and Weight Dissatisfaction Than Their Heterosexual Peers.

OBJECTIVE: Assess the health-related quality of life (HRQOL), diet quality (DQ), and weight dissatisfaction in sexual minority (SM) undergraduates. METHODS: Undergraduates (n = 690) at 2 universities completed a survey assessing HRQOL, body mass index, DQ, and weight dissatisfaction. A multivariate analysis of covariance assessed HRQOL between SM and heterosexual students. Chi-square tests and independent t tests measured weight dissatisfaction and DQ. P < 0.05 was considered statistically significant. RESULTS: Significant differences in HRQOL were observed (F[6,584] = 8.89; P < 0.001; Wilk's Λ = 0.916; partial η2 = 0.084). Sexual minority students experienced more days per month feeling sad/blue/depressed (12.0 ± 9.7 vs 6.3 ± 7.8 days; P < 0.001) and worried/tense/anxious (18.1 ± 10.2 vs 10.9 ± 9.8 days; P < 0.001); and fewer days feeling healthy and full of energy (6.8 ± 6.5 vs 11.4 ± 8.7 days; P < 0.001). Sexual minority students consumed more sugar (14.4 ± 7.9 g vs 10.2 ± 7.1 g; P = 0.020), had higher body mass indexes (25.8 ± 6.1 vs 24.4 ± 4.8; P = 0.005), and were less satisfied with their weight (30.7% vs 44.0%; P = 0.001). CONCLUSIONS AND IMPLICATIONS: Sexual minority undergraduates experience similar health disparities as other SM populations and have indicators of poorer DQ.

[Assessment of the role of nutritional and genetic determinants in the formation of the risk of diseases associated with folate cycle disorders in the population of the Omsk region].

A number of essential nutrients are involved in the folate cycle, and its effectiveness depends on the sufficient intake of them. In addition, polymorphic variants of the methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR) and methionine synthase (MTR) genes affect a wide range of biochemical reactions of the folate cycle and should also be considered as a risk factor for the development of a number of diseases. The purpose of this research was to study the prevalence of these risk factors. Material and methods. The prevalence of polymorphisms of the folate cycle genes: C677T polymorphism of the MTHFR gene and A66G polymorphism of the MTRR gene in a random stratified (by sex and age) sample of the adult population of the Omsk region [n=139, 51 men, 88 women, aged 18 to 75 years, median age 37 (26; 48) years] was studied. The identification of polymorphisms was carried out by the method of allele-specific polymerase chain reaction with an electrophoretic detection scheme. Using the food intake frequency questionnaire, the dietary intake of nutrients involved in the folate cycle was determined: B vitamins (B6, B2, B9, B12), methionine, choline, in a representative stratified sample of residents of the Omsk region [n=421, 177 men, 244 women, aged 18 to 83 years, median age 37 (23; 57) years]. Results. MTHFR genotypes (A222V С677T C>T) were distributed as follows: CC-type - 51.3%, CT - 41.0%, TT - 7.7%; MTRR genotypes (I22M A>G): AA type - 57.9%, AG - 30.3%, GG - 11.8%. The analysis of actual nutrition showed consumption below the recommended dietary intake of folates in 88.2% persons, vitamin B2 and choline - in 40.5%, vitamin B6 - in 29.2%, methionine - in 22.0%. Vitamin B12 intake was within the recommended range. Conclusion. The totality of the data presented indicates the combined influence and wide distribution of factors that determine the low efficiency of the folate cycle, and, as a result, a high risk of developing a characteristic pathology for the adult population of the region, which determines the need and priorities for prevention measures, including healthy nutrition.
