Data from: Incidence rate of community-acquired pneumonia in adults: a population-based prospective active surveillance study in three cities in South America
OBJECTIVE: To determine the incidence rate and mortality of community-acquired pneumonia (CAP) in adults in three cities in Latin America during a three-year period. DESIGN: Prospective population based study. SETTING: Healthcare facilities (outpatient centers and hospitals) in the cities of General Roca (Argentina), Rivera (Uruguay) and Concepcion (Paraguay). PARTICIPANTS: 2302 adults aged 18 years and older with CAP were prospectively enrolled between January 2012 and March 2015. MAIN OUTCOME MEASURES: Incidence rate of CAP in adults, predisposing conditions for disease, mortality at 14 days and at one year were estimated. Incidence rate of CAP, within each age group, was calculated by dividing the number of cases by the person-years of disease-free exposure time based on the last census; incidence rates were expressed per 1000 person-years. RESULTS: Median age of participants was 66 years, 46.44 % were men, 68% were hospitalized. Annual incidence rate was 7.03 (CI95% 6.64-7.44) per 1000 person-years in General Roca, 6.33 (CI95% 5.92-6.78) per 1000 person-years in Rivera and 1.76 (CI95% 1.55-2.00) per 1000 person-years in Concepcion. Incidence rates were highest in participants aged over 65 years. 82.4% had at least one predisposing condition and 48% had 2 or more (multi-morbidity). Chronic heart disease (43.6%) and smoking (37.3%) were the most common risk factors. 14-day mortality rate was 12.1% and one-year mortality was 24.9%. Multi-morbidity was associated with an increased risk of death at 14 days (OR 2.91; 2.23 to 3.80) and at 1 year (OR 3.00; 2.44 to 3.70). CONCLUSIONS: We found a high incidence rate of CAP in adults, ranging from 1.76 to 7.03 per 1000 person-years, in three cities in South America, disclosing the high burden of disease in the region. Efforts to improve prevention strategies are needed.
Data from: Catastrophic health expenditure according to employment status in South Korea: A population-based panel study
Objectives: Catastrophic health expenditure (CHE) means that medical spending of a household exceeds a certain level of capacity to pay. Previous studies of CHE have focused on benefits supported by the public sector or high medical cost incurred by treating diseases in South Korea. This study examines variance of CHE in these households according to changes in employment status. We also determine whether a relationship exists according to income level. Design: A longitudinal study. Setting: We used the Korea Welfare Panel Study (KOWEPS) conducted by the Korea Institute. Participants: These data consisted of 5,335 households during 2009-2012. Outcome measure: CHE defined as health expenditures that were 40% greater than the ability of the household to pay. Results: Households with people who experienced changes in job status from employed to unemployed (OR 2.79, 95% CI 2.06-3.78) or were unemployed with no status change (OR 1.57, 95% CI 1.28-1.92) were more likely to incur CHE compared to those who were consistently employed. In addition, low-income families that either lost a job (OR 3.52, 95% CI 2.44-5.10) or were already unemployed (OR 1.67, 95% CI 1.29-2.16) were more likely to incur CHE compared to those with a consistent job. Conclusions: Given the insecure employment status of people with low-income, they are more likely to face barriers in obtaining needed health services. Meeting their needs for health care is an important consideration.
Data from: Effect of ultrasonography surveillance in patients with liver cancer: a population-based longitudinal study
Objective Liver cancer is a growing global public health problem. Ultrasonography is an imaging tool widely used for the early diagnosis of liver cancer. However, the effect of ultrasonography surveillance (US) on the survival of patients with liver cancer is unknown. Therefore, this study examined the association between survival and US frequency during the 2 years preceding patients' liver cancer diagnosis. Methods This population-based longitudinal study was conducted in Taiwan, a region with high liver cancer incidence, by using the National Health Insurance Research Database. We compared survival between patients who received US three times or more (≥3 group) and less than three times (<3 group) during the 2 years preceding their liver cancer diagnosis, and identified the predictors for the ≥3 group. Results This study enrolled 4621 patients with liver cancer who had died between 1997 and 2010. The median survival rate was higher in the ≥3 group (1.42 years) than in the <3 group (0.51 years). Five-year survival probability was also significantly higher in the ≥3 group (14.4%) than in the <3 group (7.7%). The multivariate logistic regression results showed that the three most common positive predictors for receiving three or more US sessions were indications of viral hepatitis, gallbladder diseases, and kidney–urinary–bladder diseases; the most common negative predictors for receiving three or more US sessions were male sex and indications of abdominal pain. Conclusion Patients with liver cancer who received US three times or more during the 2 years preceding their liver cancer diagnosis exhibited a higher 5-year survival probability.
Data from: Risk factors for possible REM sleep behavior disorder: a CLSA population-based cohort study
Objective: Idiopathic REM sleep behavior disorder (RBD) is a powerful marker of prodromal neurodegenerative synucleinopathy, with 80% of patients ultimately phenoconverting to defined disease. Several environmental risk factors for RBD have been suggested, but associations vary between studies. We assessed sociodemographic, socioeconomic and clinical correlates of RBD in a 30,000-subject national cohort. Methods: Subjects aged 45-85 years in Canada were collected as part of the Canadian Longitudinal Study on Aging. Possible RBD (pRBD) was screened with the RBD-1Q, a questionnaire with 94% specificity and 87% sensitivity. To improve diagnostic reliability, subjects screening positive for apnea or non-REM parasomnia (young onset pRBD), and subjects self-reporting dementia or Parkinson's disease were excluded. A series of sociodemographic, life style and mental health variables were analysed cross-sectionally. Potential correlates were assessed via multivariable logistic regression. Results: Of 30,097 subjects, 958 (3.2%) had pRBD. Male sex (OR=2.14 ,95%CI=[1.84, 2.49]) and lower education (OR=0.95 [0.92, 0.98] were associated with pRBD. pRBD subjects had smoked more (total smoking years OR=1.006 [1.010, 1.011]) and were more likely to be moderate-heavy drinkers (OR=1.25 [1.03, 1.50]). There was a strong association between pRBD and self-reported antidepressant treatment for depression (OR=2.76 [2.22, 3.44]), psychological distress (OR=1.52 [1.37, 1.69]), mental illness (OR=2.08 [1.79, 2.41]), and post-traumatic stress disorder (OR=2.84 [2.55, 3.54]). Conclusions: Our study replicated previous reported associations between pRBD and smoking, low education and male sex, and found previously-unreported links with alcohol use and psychological distress. The risk factors for pRBD differ from those previously defined for neurodegenerative synucleinopathies.
