INTRODUCTION

Sarcoidosis is a systemic inflammatory disease characterized by non-necrotizing granulomas in involved organs, most commonly the lung. Description of patient characteristics in the Western United States is limited. Furthermore, blood-based measures that relate to clinical sarcoidosis phenotypes are lacking. We present an analysis of a prospective, longitudinal sarcoidosis cohort at a Northern Californian academic medical center.

METHODS

We enrolled 126 sarcoidosis subjects and 64 healthy controls and recorded baseline demographic and clinical characteristics. We used regression models to identify factors independently associated with pulmonary physiology. We tested whether blood transcript levels at study entry could relate to longitudinal changes in pulmonary physiology.

RESULTS

White, non-Hispanics composed ~70% of subjects. Hispanics and Blacks had a diagnostic biopsy at an age ~7 years younger than whites. Obstructive, but not restrictive, physiology characterized Scadding Stage IV patients. Subjects reporting use of immunosuppression had worse FEV1%p, FVC%p, and DLCO%p compared to subjects never treated, regardless of Scadding stage. We defined sarcoidosis disease activity by a drop in pulmonary function over 36 months and found that subjects meeting this definition had significant repression of blood gene transcripts related to T cell receptor signaling pathways, referred to as the "TCR factor."

CONCLUSION

Obstructive pulmonary physiology defined Stage IV patients which were mostly white, non-Hispanics. Genes comprising the composite gene expression score, TCR factor, may represent a blood-derived measure of T-cell activity and an indirect measure of active sarcoidosis inflammation. Validation of this measure could translate into individualized treatment for sarcoidosis patients.

Background In 2012, the Centers for Disease Control and Prevention (CDC) published guidelines supporting one-time screening for hepatitis C (HCV) in all persons born between 1945 and 1965. It is estimated that 75% of adults infected with HCV fall within this cohort. Furthermore, it is projected that this preventative health intervention would lead to the diagnosis of 800,000 unknown cases and the prevention of 120,000 deaths. Objectives The primary objectives are to measure adherence to HCV screening in a continuity practice staffed by internal medicine residents and attending physicians and to measure the effect of educational interventions to enhance HCV screening. The secondary objectives include finding whether insurance or provider status affects adherence to HCV screening. Methods In 2015, we performed a retrospective chart review of asymptomatic patients born between 1945 and 1965 to estimate the rate of HCV screening. In order to meet inclusion criteria, the patients must have had an HCV status that was unknown and must have been seen by a primary care provider ≥ 2 times between January 1 and December 31, 2013. The data extracted included whether HCV testing was ordered, whether testing was performed primarily for screening purposes, demographic information, insurance status, number of clinic visits, and whether the primary provider was a resident or attending physician. Subsequently, in 2016 we implemented an educational intervention aimed at improving these rates. Afterwards, we repeated the chart review to determine if screening rates had improved. Results Out of 294 patients reviewed pre-intervention, 200 patients were eligible for inclusion, of which 17 (8.5%) patients were offered screening for HCV, of which 13 (76.5%) patients completed testing. Following an educational intervention, 484 patients were reviewed and 100 patients were included, of which 34 (34%) patients were screened. Compared to a pre-intervention screening rate of 8.5%, post-intervention screening had improved to 34%, a 300% increase (p0.001). Conclusions Educational interventions are feasible and can lead to significant improvements in clinical practice enabling for the rapid dissemination of evolving guidelines.

Interprofessional case conferences (ICCs) offer an interactive, practical way to engage members of two or more health professions in discussions that involve learning and working together to improve patient care. Well-orchestrated ICCs provide opportunities to integrate interprofessional (IP) education into routine clinical practice. The authors provide 12 tips to support the conceptualization, planning, implementation, facilitation, evaluation, and sustainability of ICCs. They draw from extensive experience as IP educators and facilitators of ICCs and from literature on IP education, case-based learning, small-group facilitation, peer-assisted learning, and learner engagement - all of which offer insights into ICCs but have not been integrated and applied to this context.

Therapeutic targets have been defined for axial and peripheral spondyloarthritis (SpA) in 2012, but the evidence for these recommendations was only of indirect nature. These recommendations were re-evaluated in light of new insights. Based on the results of a systematic literature review and expert opinion, a task force of rheumatologists, dermatologists, patients and a health professional developed an update of the 2012 recommendations. These underwent intensive discussions, on site voting and subsequent anonymous electronic voting on levels of agreement with each item. A set of 5 overarching principles and 11 recommendations were developed and voted on. Some items were present in the previous recommendations, while others were significantly changed or newly formulated. The 2017 task force arrived at a single set of recommendations for axial and peripheral SpA, including psoriatic arthritis (PsA). The most exhaustive discussions related to whether PsA should be assessed using unidimensional composite scores for its different domains or multidimensional scores that comprise multiple domains. This question was not resolved and constitutes an important research agenda. There was broad agreement, now better supported by data than in 2012, that remission/inactive disease and, alternatively, low/minimal disease activity are the principal targets for the treatment of PsA. As instruments to assess the patients on the path to the target, the Ankylosing Spondylitis Disease Activity Score (ASDAS) for axial SpA and the Disease Activity index for PSoriatic Arthritis (DAPSA) and Minimal Disease Activity (MDA) for PsA were recommended, although not supported by all. Shared decision-making between the clinician and the patient was seen as pivotal to the process. The task force defined the treatment target for SpA as remission or low disease activity and developed a large research agenda to further advance the field.

The debate regarding anatomy laboratory teaching approaches is ongoing and controversial. To date, the literature has yielded only speculative conclusions because of general methodological weaknesses and a lack of summative empirical evidence. Through a meta-analysis, this study compared the effectiveness of instructional laboratory approaches used in anatomy education to objectively and more conclusively synthesize the existing literature. Studies published between January 1965 and December 2015 were searched through five databases. Titles and abstracts of the retrieved records were screened using eligibility criteria to determine their appropriateness for study inclusion. Only numerical data were extracted for analysis. A summary effect size was estimated to determine the effects of laboratory pedagogies on learner performance and perceptions data were compiled to provide additional context. Of the 3,035 records screened, 327 underwent full-text review. Twenty-seven studies, comprising a total of 7,731 participants, were included in the analysis. The meta-analysis detected no effect (standardized mean difference = -0.03; 95% CI = -0.16 to 0.10; P = 0.62) on learner performance. Additionally, a moderator analysis detected no effects (P ≥ 0.16) for study design, learner population, intervention length, or specimen type. Across studies, student performance on knowledge examinations was equivalent regardless of being exposed to either dissection or another laboratory instructional strategy. This was true of every comparison investigated (i.e., dissection vs. prosection, dissection vs. digital media, dissection vs. models/modeling, and dissection vs. hybrid). In the context of short-term knowledge gains alone, dissection is no better, and no worse, than alternative instructional modalities. Clin. Anat. 31:122-133, 2018. © 2017 Wiley Periodicals, Inc.

CONTEXT

Although radiation exposure is an important predictor of thyroid cancer on diagnosis of a thyroid nodule, the relationship between childhood radiation exposure and thyroid nodules has not been comprehensively evaluated.

OBJECTIVE

To examine the association between internal I-131 thyroid dose and thyroid nodules in young adults exposed during childhood.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study, we screened residents of Belarus aged ≤18 years at the time of the Chernobyl nuclear accident for thyroid disease (median age, 21 years) with thyroid palpation, ultrasonography, blood/urine analysis, and medical follow-up when appropriate. Eligible participants (N = 11,421) had intact thyroid glands and doses based on direct individual thyroid activity measurements.

MAIN OUTCOME MEASURES

Excess odds ratios per Gray (EOR/Gy, scaled at age 5 years at exposure) for any thyroid nodule and for nodules grouped by cytology/histology, diameter size, and singularity.

RESULTS

Risk of any thyroid nodule increased significantly with I-131 dose and, for a given dose, with younger age at exposure. The EOR/Gy (95% confidence intervals) for neoplastic nodules (3.82; 0.87 to 15.52) was significantly higher than for nonneoplastic nodules (0.32; 0.03 to 0.70) and did not vary by size; whereas the EOR/Gy for nonneoplastic nodules did vary by size (P = 0.02) and was 1.55 (0.36 to 5.46) for nodules ≥10 mm and 0.02 (-0.02 to 0.70) for nodules 10 mm. EORs/Gy for single and multiple nodules were comparable.

CONCLUSIONS

Childhood exposure to internal I-131 is associated with increased risk of neoplastic thyroid nodules of any size and nonneoplastic nodules ≥10 mm.

IMPORTANCE

Psoriasis is a complex inflammatory skin condition associated with serious medical comorbidities in adults, including obesity, hypertension, dyslipidemia, type 2 diabetes mellitus, psoriatic arthritis, nonalcoholic fatty liver disease, depression, anxiety, and decreased quality of life. Because psoriasis begins in childhood in almost one-third of patients, early identification of risk may be critical to minimizing effects on future health.

OBJECTIVE

To develop the first set of guidelines for comorbidity screening for patients with pediatric psoriasis based on current evidence.

EVIDENCE REVIEW

A literature review was performed using PubMed from January 1999 through December 2015. Limiting the search to human studies published in English and removing reviews and editorials produced 153 relevant manuscripts. An expert panel in psoriasis, pediatric dermatology, pediatric rheumatology, pediatric gastroenterology, pediatric endocrinology, and adult and pediatric cardiology used the patient-centered Strength of Recommendation Taxonomy (SORT) method to evaluate and grade the quality of evidence.

FINDINGS

Because of the limited number of pediatric studies published on these topics, the strength of the panel's recommendations is classified as SORT level C expert consensus recommendations. The majority of recommendations coincide with those endorsed by the American Academy of Pediatrics for the general pediatric patient but with added attention to signs and symptoms of arthritis, depression, and anxiety. The panel also identified key areas for further investigation.

CONCLUSIONS AND RELEVANCE

Patients with pediatric psoriasis should receive routine screening and identification of risk factors for associated comorbidities. These guidelines are relevant for all health care providers caring for patients with pediatric psoriasis, including primary care clinicians, dermatologists, and pediatric specialists. Because these are the first pediatric guidelines, re-review and refinement will be necessary as studies further detail, and possibly stratify, risk in affected children.

INTRODUCTION

Peyronie's disease (PD) and Dupuytren contractures (DC) are often comorbid and are believed to have a similar underlying pathophysiologic mechanism.

AIM

To investigate the prevalence of PD-like symptoms (PDLS) in men with DC.

METHODS

From October 2013 to December 2016, men who were seen and evaluated for DC were offered the opportunity to participate in an anonymous survey. The survey assessed several basic demographic and sexual health factors and included items from the International Index of Erectile Function and the Erection Hardness Scale. Men who reported PDLS were asked a series of questions derived from the Peyronie's Disease Questionnaire and for their opinions on theoretical treatment modalities for sexual problems and penile deformity.

MAIN OUTCOME MEASURE

Prevalence of PDLS in men with DC.

RESULTS

One hundred forty men with DC were invited to participate; 85 surveys were returned (response rate = 61%). Twenty-two respondents (26%, 95% confidence interval = 17-35) reported PDLS. Approximately one fourth of all respondents had an Erection Hardness Scale score lower than 3. The most common specific PDLS concerns were penile curvature (91%), length loss (55%), narrowing (36%), and hinging (32%). In men with PDLS, 73% felt at least a little bothered by the symptoms when attempting sexual activity and 40% reported having sex less frequently because of the symptoms. Just 27% of men with PDLS had ever used a treatment for a sexual concern. In terms of treatments for penile deformities, 64% of men with PDLS expressed an interest in treatment administered in the form of an in-office procedure; 41% were potentially amenable to a surgical procedure.

CONCLUSION

The prevalence of PDLS in men with DC is similar to the prevalence of DC in men diagnosed with PD. A substantial number of these men have distress and would consider standard-of-care treatments for PD. Shindel AW, Sweet G, Thieu W, et al.

BACKGROUND

Although HIV is associated with increased atherosclerotic cardiovascular disease (CVD) risk, it is unknown whether guidelines can identify HIV-infected adults who may benefit from statins. We compared the 2013 American College of Cardiology/American Heart Association and 2004 Adult Treatment Panel III recommendations in HIV-infected adults and evaluated associations with carotid artery intima-media thickness and plaque.

METHODS AND RESULTS

Carotid artery intima-media thickness was measured at baseline and 3 years later in 352 HIV-infected adults without clinical atherosclerotic CVD and not on statins. Plaque was defined as IMT >1.5 mm in any segment. At baseline, the median age was 43 (interquartile range, 39-49), 85% were men, 74% were on antiretroviral medication, and 50% had plaque. The American College of Cardiology/American Heart Association guidelines were more likely to recommend statins compared with the Adult Treatment Panel III guidelines, both overall (26% versus 14%; 0.001), in those with plaque (32% versus 17%; =0.0002), and in those without plaque (16% versus 7%; =0.025). In multivariable analysis, older age, higher low-density lipoprotein cholesterol, pack per year of smoking, and history of opportunistic infection were associated with baseline plaque. Baseline IMT (hazard ratio, 1.18 per 10% increment; 95% confidence interval, 1.05-1.33; =0.005) and plaque (hazard ratio, 2.06; 95% confidence interval, 1.02-4.08; =0.037) were each associated with all-cause mortality, independent of traditional CVD risk factors.

CONCLUSIONS

Although the American College of Cardiology/American Heart Association guidelines recommended statins to a greater number of HIV-infected adults compared with the Adult Treatment Panel III guidelines, both failed to recommend therapy in the majority of HIV-affected adults with carotid plaque. Baseline carotid atherosclerosis but not atherosclerotic CVD risk scores was an independent predictor of mortality. HIV-specific guidelines that include detection of subclinical atherosclerosis may help to identify HIV-infected adults who are at increased atherosclerotic CVD risk and may be considered for statins.
