Background: This study aimed to (1) identify profiles of high emergency department (ED) users (3+ visits/year) among 5409 patients with mental disorders (MD) based on their patterns of ED use and clinical characteristics; (2) identify sociodemographic and service use correlates linked to high ED user profiles; and (3) assess risks of death in a 12-month follow-up period, controlling for sex and age.
Methods: Using varied medico-administrative databases, this 5-year study collected patient data for six Quebec (Canada) ED. Latent class analysis was used to distinguish profiles of high ED users for a 3-year period, while bivariate analyses subsequently assessed associations between high ED user profiles and sociodemographic and service use correlates. Survival analysis were also applied to examine relationships between profile memberships of high ED users and risk of death in the 12 months following period of high ED use.
Results: Three profiles of high ED use were identified, Profile 1: 3-year recurrent very high ED users (10+ ED visits/year), Profile 2: 2-year recurrent high ED users, and Profile 3: 1-year high ED users. Profiles differed according to severity of health conditions, intensity of service use, particularly frequent hospitalizations, and risk of death: high in Profile 1, moderate in Profile 2, and low in Profile 3. Compared to 1-year high ED users, 3-year recurrent very high ED users and 2-year recurrent high ED users had poorer health and higher risk of death.
Conclusions: More targeted interventions may be improved for especially recurrent high ED users and recurrent very high ED use.

Background: Despite the growing use of social egg freezing (SEF), research focusing on its psychological aspects is lacking. This study aimed to investigate possible psychological predictors, reasons, and outcomes of SEF in German-speaking countries.
Methods: The cross-sectional study included 1,131 women (average age 31 years) who had never used medical egg freezing.
Assessing the financial burden of multimorbidity among patients aged 30 and above in India.

Background: Multimorbidity is associated with significant out-of-pocket expenditures (OOPE) and catastrophic health expenditure (CHE), especially in low- and middle-income countries like India. Despite this, there is limited research on the financial burden of multimorbidity in outpatient and inpatient care, and cross-state comparisons of CHE are underexplored.
Methods: We conducted a cross-sectional analysis using nationally representative data from the National Sample Survey 75th Round 'Social Consumption in India: Health (2017-18)', focusing on patients aged 30 and above in outpatient and inpatient care in India.

Natural gas (NG) is a promising alternative to diesel for sustainable transport, potentially reducing GHG and air quality emissions significantly. However, the GHG benefits hinge on managing methane slip, the unburned methane in the exhaust of NG engines, which carries a significant global warming potential. The CH slip from NG engines is highly dependent on engine type and operation, and effective greenhouse gas emission mitigation requires that the actual operation of real-world engines is monitored.
