Multicenter Study Observational Study
Changes in weight and weight distribution across the lifespan among HIV-infected and -uninfected men and women.
Examine body composition changes across the lifespan of HIV-infected compared to uninfected adults. Longitudinal study of antiretroviral therapy (ART)-treated HIV-infected and uninfected participants from the Multicenter AIDS Cohort Study and Women's Interagency HIV Study. Body mass index (BMI), waist (WC), hip circumference (HC), and waist-to-height ratio (WHtR) measured at semiannual visits from 1999 to 2014. ⋯ Lower BMI, WC, hip circumference, and WHtR were associated with hepatitis C infection among women only, and with substance use among all participants, and with lower CD4 cell count and shorter ART duration among HIV-infected participants. Slower BMI gain among younger HIV-infected adults may be partly explained by substance use and hepatitis C infection, and suggests that lower BMI does not represent improved health. Further analysis of muscle and fat abundance and quality will advance understanding of metabolic risk over the lifespan, a key to reducing morbidity in an aging population.

Randomized Controlled Trial
Intubation without use of stylet for McGrath videolaryngoscopy in patients with expected normal airway: A randomized noninferiority trial.
During McGrath videolaryngoscope (VL) intubation, a styletted endotracheal tube maintaining an upward distal tip angle is recommended by some manufacturers. However, a styletted endotracheal tube can elicit rare but potentially serious complications. The purpose of this study was to demonstrate that a nonstyletted tube with exaggerated curvature would be noninferior to a styletted tube for orotracheal intubation using McGrath VL in patients with expected normal airway, by comparing the time to intubation and ease of intubation. ⋯ This study shows that a nonstyletted endotracheal tube with exaggerated curvature has a similar performance to a styletted tube with a hockey-stick curvature during intubation using McGrath VL regarding time taken to successful intubation and easiness of intubation.

Do-Not-Resuscitate (DNR) and hospice care are not only applied to cancer patients but also to patients with noncancer progressive illness. However, the trends of DNR consent and hospice utilization are not well explored for noncancer patients. This study aimed to explore the trends of DNR consent and hospice care utilization among noncancer decedents in a tertiary hospital in Taiwan. ⋯ There were increased trends of DNR consent in patients with major noncancer diagnoses, and increased hospice care utilization in patients diagnosed with lung diseases and renal failure from 2010 to 2014. However, the hospice care utilization could be improved. Further study to evaluate factors associated hospice care to improve the utilization is suggested.

Comparative Study
The associations between leukocyte, erythrocyte or platelet, and metabolic syndrome in different genders of Chinese.
Leukocyte, erythrocyte or platelet and metabolic syndrome (MS) are closely correlated, and there exist gender differences. We aimed to explore the associations between the hematological parameters and MS in different genders of Chinese. This cross-sectional study included 32,900 participants (20,733 males, 12,167 females) who were enrolled in a health examination. ⋯ Gender has influences on the associations between leukocyte, erythrocyte or platelet, and MS. In both genders, higher levels of leukocyte and erythrocyte increased risks of MS. For men, platelet was a protective factor, but for women, platelet seemed as a risk factor.

The aim of this article was to assess the associations of serum 25-hydroxyvitamin D [25(OH)D] and daily sun exposure time with myopia in Korean adults. This study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) of Korean adults in 2010-2012; multiple logistic regression analyses were performed to examine the associations of serum 25(OH)D levels and daily sun exposure time with myopia, defined as spherical equivalent ≤-0.5D, after adjustment for age, sex, household income, body mass index (BMI), exercise, intraocular pressure (IOP), and education level. Also, multiple linear regression analyses were performed to examine the relationship between serum 25(OH)D levels with spherical equivalent after adjustment for daily sun exposure time in addition to the confounding factors above. ⋯ In multiple linear regression analyses, spherical equivalent was significantly associated with serum 25(OH)D concentration after adjustment for confounding factors (P = 0.002). Low serum 25(OH)D levels and shorter daily sun exposure time may be independently associated with a high prevalence of myopia in Korean adults. These data suggest a direct role for vitamin D in the development of myopia.
