METHODS We retrospectively assessed the imaging findings and clinical data of 21 patients with gastrointestinal anisakiasis. selleckchem Diagnosis was confirmed by a positive antigen (n = 16), endoscopy (n = 2), or a compatible clinical presentation, physical examination, and history of raw fish consumption (n = 3). Ultrasound findings reviewed included segmental circumferential bowel wall thickening, segmental edema of the valvulae conniventes, dilated small bowel loops with hyperperistalsis or hypoperistalsis, free fluid, and color Doppler hyperemia. RESULTS Segmental circumferential bowel wall thickening was present in all 21 patients, whereas segmental edema of the valvulae conniventes was visualized in 13 patients, moderately dilated small-bowel loops proximal to the affected segment with increased peristalsis in 14 patients, small-to-moderate ascites in 18 patients, and color Doppler hyperemia in 7 patients. The US evaluation ruled out a surgical pathologic examination in all patients, and the diagnosis of anisakiasis was suggested by the radiologist on the basis of US findings in 12 patients. CONCLUSIONS Familiarity with the suggestive US presentation of intestinal anisakiasis may allow the radiologist to propose the diagnosis of this overlooked cause of abdominal pain and may also prompt an investigation of recent raw or lightly cooked seafood ingestion. Ultrasound findings of bowel wall thickening, especially segmental edema of the valvulae conniventes, hyperperistalsis, and dilatation of small-bowel loops proximal to the affected segment, ascites, and color Doppler hyperemia, along with a history of raw fish ingestion should aid the radiologist in the diagnosis of anisakiasis. © 2020 by the American Institute of Ultrasound in Medicine.in English, Spanish ANTECEDENTES La escisión total del mesorrecto (total mesorectal excision, TME) proporciona excelentes resultados oncológicos en el tratamiento del cáncer de recto, pero los pacientes pueden presentar trastornos funcionales. Un abordaje novedoso para realizar la TME es mediante cirugía transanal mínimamente invasiva de puerto único. En esta revisión sistemática se evaluaron los resultados funcionales y la calidad de vida después de TME transanal (TaTME) y TME laparoscópica (LapTME). MÉTODOS En mayo de 2019 se realizó una búsqueda exhaustiva en las bases de datos de Pubmed, Biblioteca Cochrane, EMBASE y en los registros de ensayos clínicos. Se utilizaron las guías PRISMA. Los datos para el metaanálisis se agruparon utilizando un modelo de efectos aleatorios. RESULTADOS Se identificaron un total de 11.660 estudios, de los cuales se incluyeron 14 estudios y 6 resúmenes de congresos con 846 pacientes (599 TaTME/247 LapTME). Un número sustancial de pacientes presentó trastornos funcionales consistentes con el síndrome de resección anterior baja (low anterior resection syndrome, LARS). El metaanálisis no encontró diferencias significativas en los porcentajes de LARS grave entre los dos abordajes (razón de oportunidades, odds ratio, OR 1,13; i.c. del 95% 0,94-1,35; P = 0,18). Sin embargo, los estudios globalmente presentaron una gran heterogeneidad, así como una deficiente información sobre la evaluación funcional basal. CONCLUSIÓN No se observaron diferencias en la función entre TaTME y LapTME.BACKGROUND Chronic alcohol exposure can alter glucocorticoid receptor (GR) function in some brain areas that promotes escalated and compulsive-like alcohol intake. GR antagonism can prevent dependence-induced escalation in drinking, but very little is known about the role of GR in regulating high-risk nondependent alcohol intake. Here, we investigate the role of GR in regulating binge-like drinking and aversive responses to alcohol in the High Drinking in the Dark (HDID-1) mice, which have been selectively bred for high blood ethanol (EtOH) concentrations (BECs) in the Drinking in the Dark (DID) test, and in their founder line, the HS/NPT. METHODS In separate experiments, male and female HDID-1 mice were administered one of several compounds that inhibited GR or its negative regulator, FKBP51 (mifepristone [12.5, 25, 50, 100 mg/kg], CORT113176 [20, 40, 80 mg/kg], and SAFit2 [10, 20, 40 mg/kg]) during a 2-day DID task. EtOH consumption and BECs were measured.

Proteins in FFPE material are stable over decades but their efficient extraction and streamlined analysis by mass spectrometry (MS)-based proteomics has so far proven challenging. Here, we describe an MS-based proteomic workflow for quantitative profiling of large FFPE tissue cohorts directly from histopathology glass slides. We demonstrate broad applicability of the workflow to clinical pathology specimens and variable sample amounts, including low-input cancer tissue isolated by laser microdissection. Using state-of-the-art data dependent acquisition (DDA) and data independent (DIA) MS workflows, we consistently quantify a large part of the proteome in 100 min single-run analyses. In an adenoma cohort comprising more than 100 samples, total work up took less than a day. We observed a moderate trend towards lower protein identifications in long-term stored samples (>15 years) but clustering into distinct proteomic subtypes was independent of archival time. Our results underline the great promise of FFPE tissues for patient phenotyping using unbiased proteomics and prove the feasibility of analyzing large tissue cohorts in a robust, timely and streamlined manner.
