Depression and food insecurity are prevalent among people with HIV (PLHIV) and contribute to poor HIV outcomes. Longitudinal data can help clarify the effect of food insecurity on depression among PLHIV in the United States. We assessed the longitudinal association of food insecurity with symptoms of depression using validated measures among participants living with HIV from the Research on Access to Care in the Homeless cohort in San Francisco. We followed 346 participants for a median of 28 months. Over half of participants (55.0 %) were food insecure and 35.8 % had symptoms of depression. In adjusted models, severe food insecurity in the previous period was associated with increased depressive symptom severity (b = 1.22; p < 0.001). The association remained statistically significant in models including participant fixed effects. Severe food insecurity was also longitudinally associated with a binary variable indicating probable depression. Efforts to increase access to and participation in food security safety net programs for PLHIV could improve depression.

A growing body of research has identified food insecurity as a barrier to antiretroviral therapy (ART) adherence. We systematically reviewed and summarized the quantitative literature on food insecurity or food assistance and ART adherence. We identified nineteen analyses from eighteen distinct studies examining food insecurity and ART adherence. Of the thirteen studies that presented an adjusted effect estimate for the relationship between food insecurity and ART adherence, nine found a statistically significant association between food insecurity and sub-optimal ART adherence. Four studies examined the association between food assistance and ART adherence, and three found that ART adherence was significantly better among food assistance recipients than non-recipients. Across diverse populations, food insecurity is an important barrier to ART adherence, and food assistance appears to be a promising intervention strategy to improve ART adherence among persons living with HIV. Additional research is needed to determine the effectiveness and cost-effectiveness of food assistance in improving ART adherence and other clinical outcomes among people living with HIV in the era of widespread and long-term treatment.

A newly developed transcription-mediated amplification assay was used to detect chikungunya virus infection in 3 of 557 asymptomatic donors (0.54%) from Puerto Rico during the 2014-2015 Caribbean epidemic. Viral detection was confirmed by using PCR, microarray, and next-generation sequencing. Molecular clock analysis dated the emergence of the Puerto Rico strains to early 2013.

Hypoparathyroidism (HypoPT) is a rare (orphan) endocrine disease with low calcium and inappropriately low (insufficient) circulating parathyroid hormone levels, most often in adults secondary to thyroid surgery. Standard treatment is activated vitamin D analogues and calcium supplementation and not replacement of the lacking hormone, as in other hormonal deficiency states. The purpose of this guideline is to provide clinicians with guidance on the treatment and monitoring of chronic HypoPT in adults who do not have end-stage renal disease. We intend to draft a practical guideline, focusing on operationalized recommendations deemed to be useful in the daily management of patients. This guideline was developed and solely sponsored by The European Society of Endocrinology, supported by CBO (Dutch Institute for Health Care Improvement) and based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) principles as a methodological base. The clinical question on which the systematic literature search was based and for which available evidence was synthesized was: what is the best treatment for adult patients with chronic HypoPT? This systematic search found 1100 articles, which was reduced to 312 based on title and abstract. The working group assessed these for eligibility in more detail, and 32 full-text articles were assessed. For the final recommendations, other literature was also taken into account. Little evidence is available on how best to treat HypoPT. Data on quality of life and the risk of complications have just started to emerge, and clinical trials on how to optimize therapy are essentially non-existent. Most studies are of limited sample size, hampering firm conclusions. No studies are available relating target calcium levels with clinically relevant endpoints. Hence it is not possible to formulate recommendations based on strict evidence. This guideline is therefore mainly based on how patients are managed in clinical practice, as reported in small case series and based on the experiences of the authors.

This study describes socio-demographic, health, and work factors as well as health and safety perceptions of day laborers who reported work-related health complaints and injuries. The researchers completed a secondary data analysis of 217 interviews conducted in 2009 with day laborers in a large city. The participants reported 83 health complaints or injuries (38%) that had occurred during the prior 12 months, with 57 of these complaints or injuries resulting in lost work time. Pain and soreness of the back were the most prevalent health complaints or injuries; 66% of participants did not report their injuries, 62% reported no health and safety training, 96% reported they needed personal protective equipment (PPE), and 63% were provided with PPE. Latino day laborers reported a high 12-month prevalence of work-related health complaints and injuries. Ongoing policy work is needed to encourage injury reporting by day laborers and the provision of health and safety training and PPE to this group of workers.

Investigators believe most patients with asthma have reversible airflow obstruction with treatment, despite airway remodeling and hyperresponsiveness. There are smokers with chronic expiratory airflow obstruction despite treatment who have features of both asthma and COPD. Some investigators refer to this conundrum as the asthma-COPD overlap syndrome (ACOS). Furthermore, a subset of treated nonsmokers with moderate to severe asthma have persistent expiratory airflow limitation, despite partial reversibility. This residuum has been assumed to be due to large and especially small airway remodeling. Alternatively, we and others have described reversible loss of lung elastic recoil in acute and persistent loss in patients with moderate to severe chronic asthma who never smoked and its adverse effect on maximal expiratory airflow. The mechanism(s) responsible for loss of lung elastic recoil and persistent expiratory airflow limitation in nonsmokers with chronic asthma consistent with ACOS remain unknown in the absence of structure-function studies. Recently we reported a new pathophysiologic observation in 10 treated never smokers with asthma with persistent expiratory airflow obstruction, despite partial reversibility: All 10 patients with asthma had a significant decrease in lung elastic recoil, and unsuspected, microscopic mild centrilobular emphysema was noted in all three autopsies obtained although it was not easily identified on lung CT scan. These sentinel pathophysiologic observations need to be confirmed to further unravel the epiphenomenon of ACOS. The proinflammatory and proteolytic mechanism(s) leading to lung tissue breakdown need to be further investigated.

OBJECTIVE

Cross-sectional studies have observed that muscle weakness is associated with worse physical function among women with systemic lupus erythematosus (SLE). The present study examines whether reduced upper and lower extremity muscle strength predict declines in function over time among adult women with SLE.

METHODS

One hundred forty-six women from a longitudinal SLE cohort participated in the study. All measures were collected during in-person research visits approximately 2 years apart. Upper extremity muscle strength was assessed by grip strength. Lower extremity muscle strength was assessed by peak knee torque of extension and flexion. Physical function was assessed using the Short Physical Performance Battery (SPPB). Regression analyses modeled associations of baseline upper and lower extremity muscle strength with followup SPPB scores controlling for baseline SPPB, age, SLE duration, SLE disease activity (Systemic Lupus Activity Questionnaire), physical activity level, prednisone use, body composition, and depression. Secondary analyses tested whether associations of baseline muscle strength with followup in SPPB scores differed between intervals of varying baseline muscle strength.

RESULTS

Lower extremity muscle strength strongly predicted changes over 2 years in physical function even when controlling for covariates. The association of reduced lower extremity muscle strength with reduced physical function in the future was greatest among the weakest women.

CONCLUSION

Reduced lower extremity muscle strength predicted clinically significant declines in physical function, especially among the weakest women. Future studies should test whether therapies that promote preservation of lower extremity muscle strength may prevent declines in function among women with SLE.

OBJECTIVE

Health information technology (HIT) holds promise in increasing access to rheumatologists by improving the quality and efficiency of referrals, but few studies have examined its use for this purpose. We evaluated the use and impact of a novel electronic referral (eReferral) system in rheumatology in a safety-net health system.

METHODS

We examined eReferrals over 4 years. Our primary outcome was use of preconsultation exchange, defined as back-and-forth communication between referring and specialty care providers, facilitating triage of referrals, requests for more information, or resolution of questions without a visit. We calculated the proportion of eReferrals that underwent preconsultation exchange, time to reviewer response, and number of visits scheduled. To increase generalizability, we selected a random sample of eReferrals to undergo additional blinded, adjudicated review to assess agreement on appropriateness for preconsultation exchange.

RESULTS

Between 2008 and 2012, 2,383 eReferrals were reviewed and 2,105 were eligible for analysis. One-fourth of eReferrals were resolved without a clinic visit. The proportion of eReferrals undergoing preconsultation exchange increased over time (55% in 2008 versus 74% in 2011), and the volume of referrals also steadily increased over time. Reviewer response time averaged between 1 and 4 days. In the random sample of eReferrals that underwent adjudicated review, agreement between reviewers was high (κ = 0.72).

CONCLUSION

HIT-enabled preconsultation exchange was used for a majority of eReferrals and facilitated communication between referring clinicians and rheumatologists. This redesigned system of care allowed for triage of a high number of referrals, with many referrals determined to be appropriate for preconsultation exchange.

BACKGROUND

Repair of grade 3 and grade 4 ventral hernias is a distinct challenge, given the potential for infection, and the comorbid nature of the patient population. This study evaluates our institutional outcomes when performing single-stage repair of these hernias, with biologic mesh for abdominal wall reinforcement.

METHODS

A prospectively maintained database was reviewed for all patients undergoing repair of grade 3 (potentially contaminated) or grade 4 (infected) hernias, as classified by the Ventral Hernia Working Group. All those patients undergoing repair with component separation techniques and biologic mesh reinforcement were included. Patient demographics, comorbidities, and postoperative complications were analyzed. Univariate analysis was performed to define factors predictive of hernia recurrence and wound complications.

RESULTS

A total of 41 patients underwent single-stage repair of grade 3 and grade 4 hernias during a 4-year period. The overall postoperative wound infection rate was 15%, and hernia recurrence rate was 12%. Almost all recurrences were seen in grade 4 hernia repairs, and in those patients undergoing bridging repair of the hernia. One patient required removal of the biologic mesh. Those factors predicting hernia recurrence were smoking (P = 0.023), increasing body mass index (P = 0.012), increasing defect size (P = 0.010), and bridging repair (P = 0.042). No mesh was removed due to perioperative infection. Mean follow-up time for this patient population was 25 months.

CONCLUSIONS

Single-stage repair of grade 3 hernias performed with component separation and biologic mesh reinforcement is effective and offers a low recurrence rate. Furthermore, the use of biologic mesh allows for avoidance of mesh explantation in instances of wound breakdown or infection. Bridging repairs are associated with a high recurrence rate, as is single-stage repair of grade 4 hernias.

BACKGROUND

Historically, older patients with ulcerative colitis were not considered candidates for ileal pouch-anal anastomosis. However, more recent evidence suggests that this procedure can be performed in older patients with acceptable surgical and functional results.

OBJECTIVE

The purpose of this work was to determine whether older age is independently associated with surgical procedure type among patients with ulcerative colitis in a large national database.

DESIGN

This was a cross-sectional analysis of ulcerative colitis patients undergoing end ileostomy or IPAA, grouped by age.

SETTINGS

This study was conducted in a university teaching hospital.

PATIENTS

Patients with ulcerative colitis who underwent total proctocolectomy or completion proctectomy with either IPAA or end ileostomy from 2005 to 2012 in the American College of Surgeons National Surgery Quality Improvement Program database were included in this study.

MAIN OUTCOME MEASURES

The primary outcome was procedure type (end ileostomy or IPAA). Patient factors associated with procedure type, including age and trends over time, were examined using multivariate logistic regression.

RESULTS

Among 3635 patients with ulcerative colitis, 28.2% underwent end ileostomy and 71.8% underwent IPAA. Older patients were more likely to undergo end ileostomy than patients ≤50 years of age after adjustment for sex, smoking, BMI, frailty trait count, and ASA class (p < 0.001). The odds of end ileostomy decreased by 12% per year between 2005 and 2012 in patients aged 61 to 70 years compared with patients ≤50 years of age (adjusted OR, 0.88 per year; p = 0.021).

LIMITATIONS

We were unable to analyze other potentially important determinants of procedure type, such as surgeon, patient preference, and anal sphincter integrity.

CONCLUSIONS

Age remains strongly associated with procedure type. The use of end ileostomy, however, is decreasing over time in patients 61 to 70 years of age as evidence accumulates that IPAA is an acceptable option for older patients with ulcerative colitis (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A191).
