The incidence and prevalence of most cardiovascular disorders increase with age, and cardiovascular disease ( CVD ) is the leading cause of death and major disability in adults aged 75 and older. Despite the effect of CVD on quality of life, morbidity, and mortality in older adults, individuals aged 75 and older have been markedly underrepresented in most major cardiovascular trials, and virtually all trials have excluded older adults with complex comorbidities, significant physical or cognitive disabilities, frailty, or residence in nursing homes and assisted living facilities. As a result, current guidelines are unable to provide evidence‐based recommendations for diagnosis and treatment of older adults typical of those encountered in routine clinical practice. The objectives of this scientific statement are to summarize current guideline recommendations as they apply to older adults, identify critical gaps in knowledge that preclude informed evidence‐based decision‐making, and recommend future research to close existing knowledge gaps. To achieve these objectives, a detailed review was conducted of current American College of Cardiology/American Heart Association ( ACC / AHA ) and American Stroke Association ( ASA ) guidelines to identify content and recommendations that explicitly targeted older adults. A pervasive lack of evidence to guide clinical decision‐making in older adults with CVD was found, as well as a paucity of data on the effect of diagnostic and therapeutic interventions on outcomes that are particularly important to older adults, such as quality of life, physical function, and maintenance of independence. Accordingly, there is a critical need for a multitude of large population‐based studies and clinical trials that include a broad spectrum of older adults representative of those seen in clinical practice and that incorporate relevant outcomes important to older adults in the study design. The results of these studies will provide the foundation for future evidence‐based guidelines applicable to older adults and enhance person‐centered care of older individuals with CVD in the United States and around the world.

AbstractAlthough studies suggest that patients with limited health literacy and/or low numeracy skills may stand to gain the most from shared decision making (SDM), the impact of these conditions on the effective implementation of SDM in the emergency department (ED) is not well understood. In this article from the proceedings of the 2016 Academic Emergency Medicine Consensus Conference on Shared Decision Making in the Emergency Department we discuss knowledge gaps identified and propose consensus‐driven research priorities to help guide future work to improve SDM for this patient population in the ED.

ObjectivesTo examine outcomes of selective neck dissection (SND) in patients with human papillomavirus (HPV)‐related oropharyngeal squamous cell carcinoma (OPSCC) who present with clinical neck disease.Study DesignMulti‐institutional retrospective review.MethodsTwo institutional databases of patients with HPV‐related OPSCC were reviewed to identify patients with clinical (c) N1‐N3 neck disease who underwent SND ± adjuvant therapy.ResultsThree hundred and twenty‐four patients were identified with a median follow‐up of 49 months (range 3–199 months). All patients underwent transoral resection of the primary tumor and SND, including levels II–IV and ± levels I or V, with resection of additional nonlymphatic tissue (extended SND) as indicated by extent of disease, including the spinal accessory nerve (7%), the internal jugular vein (13%), and the sternocleidomastoid muscle (8%). Two hundred and seventy (83%) patients underwent adjuvant radiation. There were 13 (4%) regional recurrences and 19 (6%) distant recurrences. Regional control following salvage was 98%. On univariable analysis, absence of radiation was associated with regional recurrence (odds ratio [OR] 9.2, 95% confidence interval [CI] 2.9–29.4). On multivariable analysis, adjuvant radiation was associated with improved disease‐free survival (DFS) (OR 0.27, 95% CI 0.14–0.53) but lost significance for overall (OS) and disease‐specific survival (DSS) (P > 0.05). Five‐year Kaplan‐Meier estimates for OS, DSS, and DFS were 88% (95% CI 84%–92%), 93% (95% CI 89%–96%), and 83% (95% CI 78%–87%), respectively.ConclusionIn HPV‐related OPSCC presenting with clinical neck disease, a SND ± additional tissue resection and adjuvant therapy, when indicated, provides excellent long‐term regional control. Omission of radiotherapy increases the risk of regional recurrence, although it may not significantly impact OS or DSS. It appears unnecessary to routinely perform a comprehensive neck dissection.Level of Evidence4. Laryngoscope, 127:623–630, 2017

Background: We used metabolic risk factors to estimate the prevalence and clinical significance of nonalcoholic fatty liver disease in Asian Americans with hepatocellular carcinoma (HCC). Methods: This is a retrospective cohort study of 824 consecutive Asian HCC patients at Stanford University Medical Center from 1998 to 2015. Patients were subdivided as: Chinese, other East Asian (Japanese and Korean), South East Asian (Vietnamese, Thai, and Laotian), Maritime South East Asian (MSEA: Malaysian, Indonesian, Filipino, and Singaporean), and South West Asian (Indian, Pakistani, and Middle Eastern). Metabolic risk factors studied were body mass index, hypertension, type II diabetes, and hyperlipidemia. Results: Most patients were male (76%) with mean age 63 years. Metabolic risk factors were highly prevalent on presentation and increased over time (P<0.001), as did the prevalence of cryptogenic HCC (P<0.004). Compared with other Asian subgroups, MSEAs had the highest body mass index (26.3) and higher rates of type II diabetes (44% vs. 23% to 35%, P=0.004), hypertension (59% vs. 38% to 55%, P=0.04), and cryptogenic HCC (15% vs. 4% to 10%, P=0.01). They were more likely to be symptomatic on presentation (44% vs. 32% to 58%, P=0.07), less likely to present within Milan criteria (34% vs. 35% to 63%, P<0.0001), and trended toward decreased 10-year survival rates compared with other ethnic subgroups (9% vs. 25% to 32%, P=0.07). Conclusions: Metabolic risk factors were increasingly prevalent among Asian Americans with HCC. MSEAs, who had the highest incidence of these risk factors, had more advanced tumor stage and trended toward worse survival.

Key Points Under current treatment approaches, patients with LA GVHD have poor overall and failure-free survival. Levels of AREG are elevated in LA GVHD, and the AREG/EGF ratio is predictive of overall survival and nonrelapse mortality in LA GVHD.

Summary Objective Infantile spasms ( IS ) represent a severe epileptic encephalopathy presenting in the first 2 years of life. Recommended first‐line therapies (hormonal therapy or vigabatrin) often fail. We evaluated response to second treatment for IS in children in whom the initial therapy failed to produce both clinical remission and electrographic resolution of hypsarhythmia and whether time to treatment was related to outcome. Methods The National Infantile Spasms Consortium established a multicenter, prospective database enrolling infants with new diagnosis of IS. Children were considered nonresponders to first treatment if there was no clinical remission or persistence of hypsarhythmia. Treatment was evaluated as hormonal therapy (adrenocorticotropic hormone [ ACTH ] or oral corticosteroids), vigabatrin, or “other.” Standard treatments (hormonal and vigabatrin) were compared to all other nonstandard treatments. We compared response rates using chi‐square tests and multivariable logistic regression models. Results One hundred eighteen infants were included from 19 centers. Overall response rate to a second treatment was 37% (n = 44). Children who received standard medications with differing mechanisms for first and second treatment had higher response rates than other sequences (27/49 [55%] vs. 17/69 [25%], p < 0.001). Children receiving first treatment within 4 weeks of IS onset had a higher response rate to second treatment than those initially treated later (36/82 [44%] vs. 8/34 [24%], p = 0.040). Significance Greater than one third of children with IS will respond to a second medication. Choosing a standard medication ( ACTH , oral corticosteroids, or vigabatrin) that has a different mechanism of action appears to be more effective. Rapid initial treatment increases the likelihood of response to the second treatment.

AbstractMigraine is one of the world's most common neurological disorders. Current acute migraine treatments have suboptimal efficacy, and new therapeutic options are needed. Approaches targeting calcitonin gene related peptide (CGRP) signaling are clinically effective, but small molecule antagonists have not been advanced because of toxicity. In this study, we explored the axonal growth/specification collapsin response mediator protein 2 (CRMP2) as a novel “druggable” target for inhibiting CGRP release and for potential relevance for treatment of migraine pain. Collapsin response mediator protein 2 has been demonstrated to regulate N-type voltage-gated Ca2+channel activity and Ca2+-dependent CGRP release in sensory neurons. The coexpression of CRMP2 with N-type voltage-gated Ca2+channel and CGRP in trigeminal ganglia (TGs) sensory neurons suggested the possibility of a novel approach to regulate CGRP release in the trigeminal system. Screening protocols surprisingly revealed that (S)-lacosamide ((S)-LCM), an inactive analog of the clinically approved small molecule antiepileptic drug (R)-lacosamide (Vimpat), inhibited CRMP2 phosphorylation by cyclin-dependent kinase 5 in rat TG slices and decreased depolarization-evoked Ca2+influx in TG cells in culture. (S)-LCM significantly blocked capsaicin-evoked CGRP release from dural nerve terminals in the rat in ex vivo cranial cup preparation. Additionally, cephalic and extracephalic cutaneous allodynia induced in rats by activation of dural nociceptors with a cocktail of inflammatory mediators, was inhibited by oral administration of (S)-LCM. The confirmation of CRMP2 as an upstream mediator of CGRP release, together with the brain penetrance of this molecule suggests (S)-LCM as a potential therapy for acute migraine.

Abstract Background: Genome-wide association studies (GWAS) in European populations have identified genetic risk variants associated with multiple myeloma. Methods: We performed association testing of common variation in eight regions in 1,318 patients with multiple myeloma and 1,480 controls of European ancestry and 1,305 patients with multiple myeloma and 7,078 controls of African ancestry and conducted a meta-analysis to localize the signals, with epigenetic annotation used to predict functionality. Results: We found that variants in 7p15.3, 17p11.2, 22q13.1 were statistically significantly (P &lt; 0.05) associated with multiple myeloma risk in persons of African ancestry and persons of European ancestry, and the variant in 3p22.1 was associated in European ancestry only. In a combined African ancestry–European ancestry meta-analysis, variation in five regions (2p23.3, 3p22.1, 7p15.3, 17p11.2, 22q13.1) was statistically significantly associated with multiple myeloma risk. In 3p22.1, the correlated variants clustered within the gene body of ULK4. Correlated variants in 7p15.3 clustered around an enhancer at the 3′ end of the CDCA7L transcription termination site. A missense variant at 17p11.2 (rs34562254, Pro251Leu, OR, 1.32; P = 2.93 × 10−7) in TNFRSF13B encodes a lymphocyte-specific protein in the TNF receptor family that interacts with the NF-κB pathway. SNPs correlated with the index signal in 22q13.1 cluster around the promoter and enhancer regions of CBX7. Conclusions: We found that reported multiple myeloma susceptibility regions contain risk variants important across populations, supporting the use of multiple racial/ethnic groups with different underlying genetic architecture to enhance the localization and identification of putatively functional alleles. Impact: A subset of reported risk loci for multiple myeloma has consistent effects across populations and is likely to be functional. Cancer Epidemiol Biomarkers Prev; 25(12); 1609–18. ©2016 AACR.
