Frail patients who undergo surgery run a greater risk of postoperative complications, longer stays and discharge to assisted living facilities. This study suggests that frailty be assessed before surgery to allow for more informed decisions.

Cancer

A Pilot Trial of Decision Aids to Give Truthful Prognostic and Treatment Information to Chemotherapy Patients with Advanced Cancer
Smith TJ, Dow LA, Virago EA, Khatcheressian J, Matsuyama R, Lyckholm LJ
Honest communication between doctors and patients with advanced cancer is beneficial and does not cause distress or lack of hope, according to these findings. Virtually all patients who took part in this study found an honest assessment to be helpful.

Depression

Aberrant Light Directly Impairs Mood and Learning Through Melanopsin-Expressing Neurons
LeGates TA, Altimus CM, Wang H, Lee HK, Yang S, Zhao H, Kirkwood A, Weber ET, Hattar S
Irregular light schedules—caused by shift work, travel or changes in day length—negatively affect mood and learning. Even when these irregular light schedules do not interrupt sleep or circadian rhythm, mood and learning suffer.
Are Fitness, Activity, and Fatness Associated With Health-Related Quality of Life and Mood in Older Persons
Stewart KJ, Turner KL, Bacher AC, DeRegis JR, Sung J, Tayback M, Ouyang P.
Every bit counts. Even just slight amounts of physical activity, slight increases in fitness and slight decreases in body fat may improve quality of life and mood among those with mild hypertension.

Diabetes

Sex Differences in Diabetes and Risk of Incident Coronary Artery Disease in Healthy Young and Middle-Aged Adults
Kalyani RR, Lazo M, Ouyang P, Turkbey E, Chevalier K, Brancati F, Becker D, Vaidya D.
Typically, men have a greater risk of developing coronary artery disease, but women with diabetes have an equal risk of coronary artery disease compared with men.
Underuse of Health Care System by Persons With Diabetes Mellitus and Diabetic Macular Edema in the United States
Bressler NM, Varma R, Doan QV, Gleeson M, Danese M, Bower JK, Selvin E, Dolan C, Fine J, Colman S, Turpcu A
Many with diabetes are not receiving proper care to prevent the vision complications associated with the disease. Given the importance of early intervention, greater awareness is needed.

Hearing Loss

Prevalence of Hearing Aid Use among Older Adults in the United States
Chien W, Lin, F
An estimated 14.2 percent of Americans over the age of 50 who experienced hearing loss between 1999 and 2006 wear hearing aids. Hearing loss is associated with falls, dementia and cognitive decline, so hearing aids may delay onset of complications.
Hearing Loss and Falls Among Older Adults in the United States
Lin FR, Ferrucci L
Researchers believe that the interplay between hearing and balance function makes people who have hearing loss more susceptible to falls.
Hearing Loss and Incident Dementia
Lin FR, Metter EJ, O'Brien RJ, Resnick SM, Zonderman AB, Ferrucci L.
Adults with hearing loss are more likely to develop dementia, according to this study. Researchers have yet to determine whether hearing loss is an indicator of early-stage dementia or if it contributes to the disease.

Hypertension
