Food insecurity is associated with negative chronic health outcomes, yet few studies have examined how providing medically appropriate food assistance to food-insecure individuals may improve health outcomes in resource-rich settings. We evaluated a community-based food support intervention in the San Francisco Bay Area for people living with HIV and/or type 2 diabetes mellitus (T2DM) to determine the feasibility, acceptability, and potential impact of the intervention on nutritional, mental health, disease management, healthcare utilization, and physical health outcomes. The 6-month intervention provided meals and snacks designed to comprise 100% of daily energy requirements and meet nutritional guidelines for a healthy diet. We assessed paired outcomes at baseline and 6 months using validated measures. Paired t tests and McNemar exact tests were used with continuous and dichotomous outcomes, respectively, to compare pre-post changes. Fifty-two participants (out of 72 initiators) had both baseline and follow-up assessments, including 23 with HIV, 24 with T2DM, and 7 with both HIV and T2DM. Median food pick-up adherence was 93%. Comparing baseline to follow-up, very low food security decreased from 59.6% to 11.5% (p < 0.0001). Frequency of consumption of fats (p = 0.003) decreased, while frequency increased for fruits and vegetables (p = 0.011). Among people with diabetes, frequency of sugar consumption decreased (p = 0.006). We also observed decreased depressive symptoms (p = 0.028) and binge drinking (p = 0.008). At follow-up, fewer participants sacrificed food for healthcare (p = 0.007) or prescriptions (p = 0.046), or sacrificed healthcare for food (p = 0.029). Among people with HIV, 95% adherence to antiretroviral therapy increased from 47 to 70% (p = 0.046). Among people with T2DM, diabetes distress (p < 0.001), and perceived diabetes self-management (p = 0.007) improved. Comprehensive, medically appropriate food support is feasible and may improve multiple health outcomes for food-insecure individuals living with chronic health conditions. Future studies should formally test the impact of medically appropriate food support interventions for food-insecure populations through rigorous, randomized controlled designs.

This longitudinal qualitative study sought to understand how and why a livelihood intervention affected the health and health behaviors of HIV-infected Kenyan adults. The intervention included a microfinance loan, agricultural and financial training, and a human-powered water pump. In-depth interviews were conducted at two time points with intervention and control participants and program staff. We double coded interviews (n = 117) and used thematic content analysis of transcripts following an integrative inductive-deductive approach. Intervention participants described improvements in HIV health, including increased CD4 counts and energy, improved viral suppression, and fewer HIV-related symptoms. Better health was linked to improved clinic attendance and ART adherence through several mechanisms: (1) reductions in food insecurity and abject hunger; (2) improved financial stability; (3) improved productivity which enhanced social support; (4) better control over work situations; and, (5) renewed desire to prioritize their own health. Livelihood interventions may improve health by influencing upstream determinants of health behavior including food security and poverty.

A large pool of clinicians are needed to meet the growing demand for HIV preexposure prophylaxis. We surveyed a mixed group of HIV specialists and nonspecialists in the San Francisco Bay Area to determine their attitudes toward and training needs regarding prescribing preexposure prophylaxis to persons at increased risk of HIV infection. Willingness to prescribe was associated with experience in caring for HIV-infected patients (adjusted odds ratio 4.76, 95% confidence interval: 1.43 to 15.76, P = 0.01). Desire for further training was associated with concerns about drug resistance (P = 0.04) and side effects (P = 0.04) and was more common among noninfectious disease specialists. Clinicians favored online and in-person training methods.

BACKGROUND
Silicosis is a progressive lung disease resulting from the inhalation of respirable crystalline silica. Lung transplantation is the only treatment for end-stage silicosis. The aim of this study was to analyze the survival experience following lung transplantation among patients with silicosis.
METHODS
We reviewed data for all patients who underwent lung transplantation for silicosis and a matched group undergoing lung transplantation for idiopathic pulmonary fibrosis (IPF) at a single medical center between March 2006 and the end of December 2013. Survival was followed through 2015.
RESULTS
A total of 17 lung transplantations were performed for silicosis among 342 lung transplantations (4.9%) during the study period. We observed non-statistically significant survival advantage (hazard ratio 0.6; 95%CI 0.24-1.55) for those undergoing lung transplantation for silicosis relative to IPF patients undergoing lung transplantation during the same period.
CONCLUSIONS
Within the limits of a small sample, survival in silicosis patients following lung transplantation was not reduced compared to IPF. Am. J. Ind. Med. 60:248-254, 2017. © 2017 Wiley Periodicals, Inc.

OBJECTIVE
In geriatric populations, frailty is associated with poor health outcomes, including mortality. Frailty has not been examined in lupus, although components of the phenotype seem relevant.
METHODS
Women with lupus (n=152) participated in research visits in 2008-2009. Frailty was assessed by Fried's frailty phenotype criteria: low weight/unintentional weight loss, slow gait (4-m walk using sex and height criteria), weakness (grip strength using gender and body mass index criteria), exhaustion (2 specific questions) and inactivity (from physical activity questionnaire). Women accumulating 3+ components were classified as 'frail', one or two components as 'prefrail', and none as 'robust'. Physical function (36-item Short Form (SF-36) Physical Functioning subscale and Valued Life Activities disability scale), cognitive function (from a 12-test battery) and mortality were examined as outcomes. Mortality was determined as of December 2015. Multiple regression analyses examined concurrent and 2-year function controlling for age, lupus duration, race/ethnicity, glucocorticoid use, obesity, self-reported disease activity and damage and, for longitudinal analyses, baseline function. Mortality analyses controlled for age, lupus duration and baseline disease damage scores.
RESULTS
Mean age was 48 (±12) years, mean lupus duration was 16 (±9) years. 20% of the sample was classified as frail and 50% as prefrail. Frail women had significantly worse physical functioning than both robust and prefrail women and were more likely to have cognitive impairment. Frail women were also more likely to experience declines in functioning and onset of cognitive impairment. Mortality rates were significantly higher in the frail group (frail 19.4%; prefrail 3.9%; robust 2.3%). Odds (95% CI) of death for frail women were elevated, even after adjusting for age, lupus duration and baseline disease damage (5.9 (0.6 to 57.1)).
CONCLUSIONS
Prevalence of frailty in this sample of women with lupus was higher than in samples of older adults. Frailty was associated with poor physical and cognitive function, functional declines and mortality.

BACKGROUND
Approximately 28% of patients with gastrointestinal (GI) cancers will receive targeted therapy (TT) because of the associated increases in survival. Only four studies have examined the symptom experience of these patients. To date, no studies have evaluated for differences in symptom occurrence, severity, and distress between patients who received chemotherapy (CTX) alone (n=304) or CTX with TT (n=93).
METHODS
Patients completed self-report questionnaires, approximately one week after they received CTX. A modified version of the Memorial Symptom Assessment Scale (MSAS) was used to obtain data on symptom occurrence, severity, and distress. Binary logistic regression analyses were used to test for differences in symptom occurrence rates between the two treatment groups. Ordinal logistic regression analyses were used to test for differences in severity and distress ratings between the two treatment groups.
RESULTS
Patients who received CTX with TT were significantly younger (P=0.009); were diagnosed with cancer longer (P=0.004); had a higher number of prior treatments (P=0.024); had metastatic disease, specifically to the liver (P<0.001); had a diagnosis of anal, colon, rectum, or colorectal cancer (CRC) (P<0.001); and were positive for detection of B-Raf proto-oncogene, serine/threonine kinase (BRAF) and Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations (both P<0.001). In addition, CTX treatment regimens were significantly different between the two groups (P<0.001). After controlling for significant covariates, patients who received TT reported lower occurrence rates for lack of energy, cough, feeling drowsy, and difficulty sleeping (all, P<0.05). Patients who received TT reported lower severity scores for dry mouth (P=0.034) and change in the way food tastes (P=0.035). However, they reported higher severity scores for "I don't look like myself" (P=0.026). No differences in symptom distress scores were found between the two treatment groups.
CONCLUSIONS
This study is the first to evaluate for differences in the symptom experience of GI cancer patients who received CTX alone or CTX with TT using a multidimensional symptom assessment scale. While between group differences in patients' symptom experiences were identified, both treatment groups warrant ongoing assessments to optimally manage their symptoms.
