Article Synopsis
  • The study investigates the effects of using albumin versus lactated Ringer's solution for replacing ascites after living donor liver transplantation (LT) on recovery times and kidney health.
  • A total of 72 patients were enrolled, and results showed no significant difference in time to first flatus between the two groups.
  • However, the albumin group had a better kidney function and lower acute kidney injury (AKI) rates compared to the lactated Ringer's group in the days following surgery.

While a large literature connects family environments characterized by access to two married biological parents to better child mental health outcomes, we know less about the mechanisms linking family structure to mental health outcomes for children living in other family structures. While essentialist theory suggests that access to both male and female parents will be an important determinant of child mental health, some research directly comparing single-mother and single-father families found no difference in child outcomes by parent gender, suggesting evidence for more structural theories of gender. However, most of this research uses data from Western countries and seldom extends to examining mental health outcomes.

The aim of this study is two-fold: to discern patterns in pathways of work and family transitions among young women (aged 24-39 years) whose decisions and behaviors toward labor force participation, marriage, and parenthood are considerably shaped by social constraints and gender norms; and to examine whether and to what extent work and family pathways are associated with later health. Using data from a longitudinal survey based on a large sample of adult women in Korea ( = 2418), we identified eight dominant pathways of employment, marriage, and parenthood among young women and found that educational attainment and family values are strong predictors of these work-family pathways. We also found that the timing and sequencing of work-family pathways appears to be associated with later health outcomes.

Objectives: We examined how experiencing low income multiple times is associated with depressive symptoms over the life course to better understand the influence of low income experience on psychological well-being.

Methods: We employed fixed effects models to estimate the association between low income experience and depressive symptoms using data from a longitudinal survey of a representative sample of adults in Korea (N=6,930). We also considered age variations given different perspectives and social circumstances related to different ages and family stages over the life course that potentially modify the association.

Forest wildfires consume and redistribute carbon within forest carbon pools. Because the incidence of wildfires is unpredictable, quantifying wildfire effects is challenging due to the lack of prefire data or controls from experiments over a large landscape. We explored a quasi-experimental method, propensity score matching, to estimate wildfire effects on aboveground forest woody carbon mass in Washington and Oregon, United States.

Background: Despite the critical role that Emergency Medical Services (EMS) provides in the health care system, racial/ethnic treatment disparities in EMS remain relatively unexamined.

Objective: To investigate racial/ethnic treatment disparities in pain assessment and pain medication administration in EMS.

Research Design: A retrospective analysis was performed on 25,732 EMS encounters from 2015 to 2017 recorded in the Oregon Emergency Medical Services Information System using multivariate logistic regression models to examine the role of patient race/ethnicity in pain assessment and pain medication administration among patients with a traumatic injury.

Purpose Social contact is known to be vital for older adults' mental and physical health but, because communication impairments often co-occur with other types of disability, it is difficult to generalize about the relative impact of a communication impairment on the social relationships of older adults. Specific aims of the study were to examine whether the severity of a communication impairment was associated with a range of social measures and to examine the association between these characteristics and psychological well-being. Method Community-dwelling older adults ranging in age from 65 to 94 were recruited for the study of Communication, Health, Aging, Relationship Types and Support.

Article Synopsis
  • The study investigates smoking behaviors among Veterans, highlighting the need to identify unique military and sociodemographic factors that affect smoking rates to improve cessation efforts.
  • Data from the 2010 National Survey of Veterans was analyzed, revealing that 17% of respondents were current smokers, with certain demographic and military experiences influencing smoking status.
  • Findings indicate that factors like female gender, low educational attainment, and exposure to trauma during service can increase smoking likelihood, while indicators such as higher income and service-related disabilities correlate with being a non-smoker.

Article Synopsis
  • Self-rated health (SRH) is an important measure for understanding health disparities across different racial and ethnic groups, but its effectiveness varies by race.
  • A study analyzing data from older adults (55-84 years) found that SRH predicts mortality risk less accurately for non-Hispanic Blacks and Hispanics compared to non-Hispanic Whites.
  • The differences in predictive validity are not fully explained by factors like socioeconomic status, immigration status, or cause of death, indicating that health evaluations may differ significantly across racial and ethnic backgrounds.

Objectives: The high predictive validity of self-rated health (SRH) is a major strength of this widely used population health measure. Recent studies, however, noted that the predictive validity varies across population subgroups. The aim of this study is to examine respondents' age as a moderator of SRH predictive validity with respect to subsequent mortality risk.

Through this cross-sectional study the authors explore how stressors, social support, and religious practice are associated with the general well-being of 147 Korean adult immigrants through interviews. Hierarchical regression analysis reveals that low English proficiency and financial hardship are significantly related to low general well-being. However, high social support and religious practice are significantly associated with high general well-being.

Article Synopsis
  • The educational gradient of U.S. adult mortality became steeper from 1960 to the mid-1980s, with unclear trends afterward due to limited research.
  • Results from a study using data from 1986 to 2006 indicate that for white and black men, mortality risk declined more significantly for those with higher education levels, particularly among older age groups.
  • The trend also showed a steeper gradient for white women, while for black women, there was a slight and marginally significant steepening attributed to decreased mortality risk in college-educated women compared to those with lower education levels.

Article Synopsis
  • Three pilot studies were conducted to gather data on sexual assault perpetration among adult men in the U.S., using random digit-dial sampling and different administration methods (telephone and Web).
  • Response rates were low across all studies, but around 40% of the 97 participating men disclosed engaging in some form of sexual assault behavior.
  • Surprisingly, telephone respondents exhibited a broader range of reported sexual assault behaviors, and it was suggested that providing multiple participation options could improve response rates in future studies.
