#1
Gregory W Ruhnke, Willard G Manning, David T Rubin, David O Meltzer
PURPOSE: Because the effect of physician supply on utilization remains controversial, literature based on non-Medicare populations is sparse, and a physician supply expansion is under way, the potential for physician-induced demand across diverse populations is important to understand. A substantial proportion of gastrointestinal endoscopies may be inappropriate. The authors analyzed the impact of physician supply, practice patterns, and clinical history on esophagogastroduodenoscopy (EGD, defined as discretionary) among patients hospitalized with lower gastrointestinal bleeding (LGIB)...

Digital breast tomosynthesis (DBT) has shown potential to improve breast cancer screening and diagnosis compared to digital mammography (DM). The FDA approved DBT use in conjunction with conventional DM in 2011, but coverage was approved by CMS recently in 2015. Given changes in coverage policies, it is important to monitor diffusion of DBT by insurance type. This study examined DBT trends and estimated associations with insurance type. From June 2011 to September 2014, DBT use in 22 primary care centers in the Dartmouth -Brigham and Women's Hospital Population-based Research Optimizing Screening through Personalized Regimens research center (PROSPR) was examined among women aged 40-89...

AIMS: Pediatric esophagogastroduodenoscopy requires deep sedation as it involves stimulation of the airway. Frequency of adverse events is higher with esophagogastroduodenoscopy. Hence, monitoring needs sedation scales like the Dartmouth Operative Condition Scale that identifies safe states of sedation. This study aims at validating the Adapted Dartmouth Operative Condition Scale for sedation rating by pediatricians during pediatric esophagogastroduodenoscopy. METHODS: Items in the Dartmouth Operating Conditions Scale were adapted for pediatric esophagogastroduodenoscopy...

REVIEW
Francine B de Abreu, Xiaoying Liu, Gregory J Tsongalis
Pancreatic cancer is considered one of the most lethal cancers being the fourth leading cause of cancer deaths in adults in the United States because of the lack of early signs and symptoms and the lack of early detection. Pancreatic ductal adenocarcinoma (PDAC) is the most common histological type among pancreatic cancers, representing 80%-90% of all solid tumors of the pancreas. The majority of PDAC develops from three precursor lesions: pancreatic intraepithelial neoplasia, intraductual papillary mucinous neoplasm and mucinous cystic neoplasm...

BACKGROUND: Melanoma in situ (MIS) is a noninvasive form of melanoma for which nonsurgical therapeutic options continue to be explored. The off-label use of topical 5% imiquimod cream in the management of MIS has shown potential but reported recurrence rates vary considerably between 0% and 40%. Furthermore, the long-term efficacy of imiquimod is not well established. OBJECTIVE: To determine the recurrence rate of MIS among patients treated with topical 5% imiquimod cream at Dartmouth-Hitchcock Medical Center with at least 1 year of follow-up...

PURPOSE: Medicare beneficiary spending patterns reflect those of the 306 Hospital Referral Regions where physicians train, but whether this holds true for smaller areas or for quality is uncertain. This study assesses whether cost and quality imprinting can be detected within the 3,436 Hospital Service Areas (HSAs), 82.4 percent of which have only 1 teaching hospital, and whether sponsoring institution characteristics are associated. METHODS: We conducted a secondary, multi-level, multivariable analysis of 2011 Medicare claims and American Medical Association Masterfile data for a random, nationally representative sample of family physicians and general internists who completed residency between 1992 and 2010 and had more than 40 Medicare patients (3,075 physicians providing care to 503,109 beneficiaries)...

Targeted genomic profiling (TGP) using massively parallel DNA sequencing is becoming the standard methodology in clinical laboratories for detecting somatic variants in solid tumors. The variety of methodologies and sequencing platforms in the marketplace for TGP has resulted in a variety of clinical TGP laboratory developed tests (LDT). The variability of LDTs is a challenge for test-to-test and laboratory-to-laboratory reliability. At the University of Vermont Medical Center (UVMMC), we validated a TGP assay for solid tumors which utilizes DNA hybridization capture and complete exon and selected intron sequencing of 29 clinically actionable genes...

BACKGROUND: Community Health Centers (CHCs) funded by Section 330 of the Public Health Service Act are an essential part of the health care safety net in the US. The Patient Protection and Affordable Care Act expanded the program significantly, but the extent to which the availability of CHCs improve access to care in general is not clear. In this paper, we examine the associations between the availability of CHC services in communities and two key measures of ambulatory care access - having a usual source of care and having any office-based medical visits over a one year period...

Motivation: Checking concordance between reported sex and genotype-inferred sex is a crucial quality control measure in genome-wide association studies (GWAS). However, limited insights exist regarding the true accuracy of software that infer sex from genotype array data. Results: We present seXY, a logistic regression model trained on both X chromosome heterozygosity and Y chromosome missingness, that consistently demonstrated >99.5% sex inference accuracy in cross-validation for 889 males and 5,361 females enrolled in prostate cancer and ovarian cancer GWAS...

BACKGROUND AND OBJECTIVES: Thoracic epidural analgesia can reduce postoperative pain and cardiopulmonary morbidity, but it is associated with a high rate of clinical failure. Up to 50% of clinical failure is thought to be related to technical insertion. In this study, patients undergoing thoracic surgery were randomized to one of two catheter insertion techniques: fluoroscopically guided or conventional loss of resistance with saline/air. Our primary aim was to examine whether fluoroscopic guidance could increase the incidence of correct catheter placement and improve postoperative analgesia...
