Gallstone Ileus With Persistent Cholelithiasis and Choledocholithiasis.

Gallstone ileus is an uncommon but well-described occurrence in general surgery. However, discrepancy regarding optimal surgical management with 1 or 2 stage operation is still debated. This case report presents a 73-year-old woman who presented to the emergency department (ED) with a small bowel obstruction due to a gallstone lodged in a portion of the proximal ileum. The patient was also noted to have persistent cholelithiasis and cholecystoduodenal fistula. A single-stage surgery involving enterolithotomy, cholecystectomy, fistula repair, and cholangioscopy was performed. The patient progressed well and was discharged home without recurrent symptoms. Therefore, in a hemodynamically stable patient with persistent cholelithiasis or choledocholithiasis, it is reasonable to perform a definitive single-stage operation.

Compulsive alcohol consumption is regulated by dorsal striatum fast-spiking interneurons.

Compulsive alcohol consumption is a core, treatment-resistant feature of alcohol use disorder. The dorsomedial and dorsolateral striatum support goal-directed and habitual action strategies, respectively. How ethanol targets dorsolateral striatum to drive compulsive consumption is poorly understood. Parvalbumin-expressing striatal fast-spiking interneurons comprise ~1% of the total neuronal striatal population, are enriched dorsolaterally and are functionally modulated by ethanol. To test whether fast-spiking interneurons are necessary for the development of compulsive ethanol consumption, we selectively ablated these neurons in adult male and female C57BL/6 J mice undergoing a voluntary chronic intermittent ethanol consumption paradigm followed by a compulsive ethanol drinking assay. Fast-spiking interneuron ablation curtailed the development of organized ethanol lick sequence behavior, reduced ethanol consumption, and abrogated compulsive consumption of ethanol with the added bitterant quinine. In contrast, fast-spiking interneuron ablation did not affect any index of water or sucrose consumption. These data causally implicate the minority striatal fast-spiking interneuron population as a key component of compulsive ethanol consumption.

Graduate perception of cosmetic surgery training in plastic surgery residency and fellowship programs.

BACKGROUND: As the demand for cosmetic surgery continues to rise, plastic surgery programs and the training core curriculum have evolved to reflect these changes. This study aims to evaluate the perceived quality of current cosmetic surgery training in terms of case exposure and educational methods. METHODS: A 16-question survey was sent to graduates who completed their training at a U.S. plastic surgery training program in 2017. The survey assessed graduates' exposure to cosmetic surgery, teaching modalities employed and their overall perceived competence. Case complexity was characterized by the minimum number of cases needed by the graduate to feel confident in performing the procedure. RESULTS: There was a 25% response rate. The majority of respondents were residents (83%, n=92) and the remaining were fellows (17%, n=18). Almost three quarters of respondents were satisfied with their cosmetic training. Respondents rated virtual training as the most effective learning modality and observing attendings' patients/cases as least effective. Perceived competence was more closely aligned with core curriculum status than case complexity, i.e. graduates feel more prepared for core cosmetic procedures despite being more technically difficult than non-core procedures. CONCLUSIONS: Despite the variability in cosmetic exposure during training, most plastic surgery graduates are satisfied with their aesthetic training. Incorporation of teaching modalities, such as virtual training, can increase case exposure and allow trainees more autonomy. The recommended core curriculum is adequately training plastic surgery graduates for common procedures and more specialized procedures should be consigned to aesthetic fellowship training.

Sex Disparity in Academic Rank and Industry Payments to Plastic Surgeons.

INTRODUCTION: Despite increasing representation in surgery, women continue to lag behind men in important metrics. Little is known on how industry funding may also contribute to this ongoing disparity. This article seeks to quantify industry payments to academic plastic surgeons (APSs) by sex and examine the relationship between funding and academic achievement. METHODS: We conducted a cross-sectional analysis of industry payments disbursed to APSs in 2017. Faculty were identified using departmental listings of Accreditation Council for Graduate Medical Education plastic surgery residency programs. Payments were identified via the Center for Medicare and Medicaid Services open payment database. Academic achievement was assessed using rank (eg, assistant professor), leadership designation (eg, division head), and Scopus H-index and then controlled for time in practice. RESULTS: Of the 805 APSs, the majority were male (82% male vs 18% female, P < 0.0001). Significant sex differences emerged in average yearly industry contributions (men, US $3202, vs women, US $707; P < 0.0001). Across all academic ranks, men received significantly higher payments than women (P < 0.0500). Men constituted 93% of full professors and were almost twice as likely to hold additional leadership positions compared with women (odds ratio, 1.82; P = 0.0143). After adjustment for time in practice, there was no difference in H-indices between male and female APSs, although payment disparity persisted (P < 0.0001). CONCLUSIONS: Substantial sex-based disparities exist among APSs' academic rank and leadership attainment, which is not attributed to differences in academic qualifications or experience. To better elucidate the sources of this disparity, future studies should assess sexed differences in payment types. Furthermore, we urge for increased transparency in the selection process for industry payments.

Common variants in HSPB7 and FRMD4B associated with advanced heart failure.

BACKGROUND: Heart failure results from abnormalities in multiple biological processes that contribute to cardiac dysfunction. We tested the hypothesis that inherited variation in genes of known importance to cardiovascular biology would thus contribute to heart failure risk. METHODS AND RESULTS: We used the ITMAT/Broad/CARe cardiovascular single-nucleotide polymorphism array to screen referral populations of patients with advanced heart failure for variants in approximately 2000 genes of predicted importance to cardiovascular biology. Our design was a 2-stage case-control study. In stage 1, genotypes in Caucasian patients with heart failure (n=1590; ejection fraction, 32+/-16%) were compared with those in unaffected controls (n=577; ejection fraction, 67+/-8%) who were recruited from the same referral centers. Associations were tested for independent replication in stage 2 (308 cases and 2314 controls). Two intronic single-nucleotide polymorphisms showed replicated associations with all-cause heart failure as follows: rs1739843 in HSPB7 (combined P=3.09x10(-6)) and rs6787362 in FRMD4B (P=6.09x10(-6)). For both single-nucleotide polymorphisms, the minor allele was protective. In subgroup analyses, rs1739843 associated with both ischemic and nonischemic heart failure, whereas rs6787362 associated principally with ischemic heart failure. Linkage disequilibrium surrounding rs1739843 suggested that the causal variant resides in a region containing HSPB7 and a neighboring gene, CLCNKA, whereas the causal variant near rs6787362 is probably within FRMD4B. Allele frequencies for these single-nucleotide polymorphisms were substantially different in African Americans (635 cases and 714 controls) and showed no association with heart failure in this population. CONCLUSIONS: Our findings identify regions containing HSPB7 and FRMD4B as novel susceptibility loci for advanced heart failure. More broadly, in an era of genome-wide association studies, we demonstrate how knowledge of candidate genes can be leveraged as a complementary strategy to discern the genetics of complex disorders.

Concept, design and implementation of a cardiovascular gene-centric 50 k SNP array for large-scale genomic association studies.

A wealth of genetic associations for cardiovascular and metabolic phenotypes in humans has been accumulating over the last decade, in particular a large number of loci derived from recent genome wide association studies (GWAS). True complex disease-associated loci often exert modest effects, so their delineation currently requires integration of diverse phenotypic data from large studies to ensure robust meta-analyses. We have designed a gene-centric 50 K single nucleotide polymorphism (SNP) array to assess potentially relevant loci across a range of cardiovascular, metabolic and inflammatory syndromes. The array utilizes a "cosmopolitan" tagging approach to capture the genetic diversity across approximately 2,000 loci in populations represented in the HapMap and SeattleSNPs projects. The array content is informed by GWAS of vascular and inflammatory disease, expression quantitative trait loci implicated in atherosclerosis, pathway based approaches and comprehensive literature searching. The custom flexibility of the array platform facilitated interrogation of loci at differing stringencies, according to a gene prioritization strategy that allows saturation of high priority loci with a greater density of markers than the existing GWAS tools, particularly in African HapMap samples. We also demonstrate that the IBC array can be used to complement GWAS, increasing coverage in high priority CVD-related loci across all major HapMap populations. DNA from over 200,000 extensively phenotyped individuals will be genotyped with this array with a significant portion of the generated data being released into the academic domain facilitating in silico replication attempts, analyses of rare variants and cross-cohort meta-analyses in diverse populations. These datasets will also facilitate more robust secondary analyses, such as explorations with alternative genetic models, epistasis and gene-environment interactions.
