OBJECTIVE
To investigate whether time on antiretroviral therapy (ART) is associated with improvements in food security and nutritional status, and the extent to which associations are mediated by improved physical health status.
DESIGN
The Uganda AIDS Rural Treatment Outcomes study, a prospective cohort of HIV-infected adults newly initiating ART in Mbarara, Uganda.
METHODS
Participants initiating ART underwent quarterly structured interview and blood draws. The primary explanatory variable was time on ART, constructed as a set of binary variables for each 3-month period. Outcomes were food insecurity, nutritional status, and PHS. We fit multiple regression models with cluster-correlated robust estimates of variance to account for within-person dependence of observations over time, and analyses were adjusted for clinical and sociodemographic characteristics.
RESULTS
Two hundred twenty-eight ART-naive participants were followed for up to 3 years, and 41% were severely food insecure at baseline. The mean food insecurity score progressively declined (test for linear trend P < 0.0001), beginning with the second quarter (b = -1.6; 95% confidence interval: -2.7 to -0.45) and ending with the final quarter (b = -6.4; 95% confidence interval: -10.3 to -2.5). PHS and nutritional status improved in a linear fashion over study follow-up (P < 0.001). Inclusion of PHS in the regression model attenuated the relationship between ART duration and food security.
CONCLUSIONS
Among HIV-infected individuals in Uganda, food insecurity decreased and nutritional status and PHS improved over time after initiation of ART. Changes in food insecurity were partially explained by improvements in PHS. These data support early initiation of ART in resource-poor settings before decline in functional status to prevent worsening food insecurity and its detrimental effects on HIV treatment outcomes.

OBJECTIVE
To evaluate the association between self-reported diabetes and the risk of breast cancer (BC) and its interaction with moderate-intensity physical activity in pre- and postmenopausal Mexican women.
RESEARCH DESIGN AND METHODS
A population-based case-control study was conducted using 1,000 incident case subjects and 1,074 control subjects. Blood samples and information on health, diet, physical activity, and anthropometric measurements were obtained.
RESULTS
The association between diabetes and BC risk decreased with increasing tertiles of moderate-intensity physical activity (odds ratio [OR] = 4.9 [95% CI 2.3-10.8]; 3.0 [1.3-6.9]; and 1.0 [0.1-9.2], respectively, for each tertile) (test for interaction = 0.04). Compared with the women in the lowest tertiles, increased risk was observed in those premenopausal women with the highest serum C-peptide, IGF-1, and IGF-1 binding protein 3 levels.
CONCLUSIONS
Moderate-intensity physical activity can substantially ameliorate the increased BC risk in diabetic women.

These guidelines were developed and updated by an interdisciplinary group of experts based on clinical experience and available scientific evidence. The goal of these guidelines is to help patients with cancer experience the best quality of life possible throughout the illness trajectory by providing guidance for the primary oncology team for symptom screening, assessment, palliative care interventions, reassessment, and afterdeath care. Palliative care should be initiated by the primary oncology team and augmented by collaboration with an interdisciplinary team of palliative care experts.

BACKGROUND
Cooccurring pain, mood disorders, and substance abuse are common in HIV-infected patients. Our objective was to investigate the relationship between pain, alone and in the context of mood disorders and substance abuse, on clinic utilization, antiretroviral therapy adherence, and virologic suppression.
METHODS
Pain, mood disorders, and substance abuse were assessed at the first visit. No-show and urgent visits were measured over a 1-year period. Models were adjusted for age, race, sex, insurance status, CD4(+) T-lymphocyte count, and HIV risk factor.
RESULTS
Among 1521 participants, 509 (34%) reported pain, 239 (16%) had pain alone, 189 (13%) had pain and a mood disorder, and 30 (2%) had pain and substance abuse. In univariate models, participants with pain, mood disorders, and substance abuse had higher odds of a no-show visit than those without these conditions [odds ratio (OR), 1.4; 95% confidence interval (CI), 1.1-1.8; OR, 1.5; 95% CI, 1.2-1.9; OR, 2.0; 95% CI, 1.4-2.8, respectively]. In the multivariable model, pain increased the odds of a no-show visit only in participants without substance abuse (OR, 1.5; 95% CI, 1.1-1.9) and pain reduced the odds of a no-show visit in participants with substance abuse (OR, 0.5; 95% CI, 0.2-0.9; P for interaction = 0.0022).
CONCLUSIONS
In this study, pain increased the odds of no-show visits but only for participants without substance abuse. Because pain, mood disorders, and substance abuse are highly prevalent in HIV-infected patients, our findings have implications for HIV treatment success. Interventions that incorporate pain management may be important for improving health outcomes in patients living with HIV infection.
