We emphasize that, even with the extensive degradation of PNC human remains and the process of curation of samples, it was possible to recover helminth aDNA. The origin of PNC individuals confirms that these infections were brought to Brazil from western and central Africa during the colonial era. V.In Brazil, flaviviruses have caused massive outbreaks. Surveillance programs designed to monitor virus activity in vectors provides a system for mapping disease distribution and for identifying specific vector species for targeted control. The present study aimed to describe the detection, whole genome characterization and phylogenetic analysis of Ilheus virus (ILHV) and Iguape virus (IGUV) strains obtained from historical mosquito's samples. Twelve isolates of pooled mosquito specimens (inoculated in neonate mouse brain) collected in the state of São Paulo, Brazil, in 1993, 1994 and 1997 were investigated. Viral RNA was extracted and analyzed by qRT-PCR using Flavivirus genus-specific primers. Positive samples were sequenced and underwent phylogenetic analyses. Flavivirus was detected in 50% of the specimens. Positive samples were successfully Sanger sequenced. Three Anopholes cruzii pools collected in 1994 were positive for IGUV. One Culex sp. pool, one Anopheles triannulatus pool, and one Coquillettidia juiruses and their evolutionary trends in Brazil, an endemic country for several arbovirus. in In-depth studies of ILHV and IGUV including vector competence and molecular studies are needed to shed light on their epidemiology and potential risk of future emergence. V.BACKGROUND Patients with aortic stenosis are nearly twice as likely to have a diagnosis of gout compared with individuals without aortic valve disease. METHODS This retrospective study evaluated consecutive adults age ≥65 years with aortic stenosis between December 2012 and November 2016 who underwent at least 2 transthoracic echocardiograms (TTEs) separated by at least 1 year. Severe aortic stenosis was defined as any combination of an aortic valve peak velocity ≥4.0 m/sec, mean gradient ≥40 mm Hg, aortic valve area ≤1 cm2, or decrease in left ventricular ejection fraction as a result of aortic stenosis. RESULTS Of the 699 study patients, gout was present in 73 patients (10%) and not found in 626 patients (90%). Obatoclax ic50 Median follow-up was 903 days [552-1302] for patients with gout and 915 days [601-1303] for patients without gout (P = 0.60). The presence of severe aortic stenosis on follow-up transthoracic echocardiogram was more frequent in patients with gout compared to those without gout (74% vs 54%, P = 0.001; hazard ratio [HR] 1.45 [1.09-1.93]), even among the 502 patients without severe aortic stenosis at baseline (63% vs 39%, P = 0.003; hazard ratio 1.43 [1.07-1.91]). Gout remained associated with the development of severe aortic stenosis after multivariable adjustment (adjusted hazard ratio [aHR] 1.46 [1.03-2.08], P = 0.03). The annualized reduction in aortic valve area was numerically greater in the group with gout compared with the group without gout (-0.10 cm2/y [-0.18, -0.03] vs -0.08 cm2/y [-0.16, -0.01], P = 0.09); annualized change in peak velocity and mean gradient did not differ between groups. CONCLUSIONS Progression to severe aortic stenosis was more frequent in patients with gout compared with those without gout, supporting the hypothesis that gout is a risk factor for aortic stenosis. Published by Elsevier Inc.PURPOSE Acute mountain sickness commonly occurs following ascent to high altitude and is aggravated following sleep. Cephalad fluid shifts have been implicated. We hypothesized that sleeping with the upper body elevated by 30º reduces the risk of acute mountain sickness. METHODS In a pragmatic, randomized, observer-blinded field study at 4554 meters altitude, we investigated 134 adults aged 18-70 years with a Lake Louise score between 3 and 12 points on the evening of their arrival at the altitude. The individuals were exposed to sleeping on an inflatable cushion elevating the upper body by 30º or on a sham pillow in a horizontal position. The primary endpoint was the change in the Acute Mountain Sickness-Cerebral (AMS-C) score in the morning after sleeping at an altitude of 4554 meters compared with the evening before. Sleep efficiency was the secondary endpoint. RESULTS Among 219 eligible mountaineers, 134 fulfilled the inclusion criteria and were randomized. The AMS-C score increased by 0.250 ± 0.575 in the control group and by 0.121 ± 0.679 in the intervention group (difference 0.105; 95% confidence interval, -0.098-0.308; P = .308). Oxygen saturation in the morning was 79% ± 6% in the intervention group and 78% ± 6% in the control group (P = .863). Sleep efficiency did not differ between groups (P = .115). CONCLUSIONS Sleeping with the upper body elevated by 30° does not lead to relevant reductions in acute mountain sickness symptoms or hypoxemia at high altitude. BACKGROUND Embryology of the human pancreas is very complex and any alteration in its development may lead to congenital biliopancreatic malformations and anomalies not thoroughly studied in literature. We here report a case of trifurcation of the Wirsung duct, avery unusual variant of the main pancreatic duct. METHOD An 80- year-old woman underwent a magnetic resonance imaging (MRI) of the abdomen and a magnetic resonance cholangiopancreatography (MRCP) to characterize a hypoechoic lesion of the pancreas detected with ultrasonography. RESULTS MRI and MRCP showed a 24-mm multicystic lesion communicating with a prominent main pancreatic duct, consistent with an intraductal papillary mucinous neoplasm, as well as an ansa pancreatica. Moreover a bifidity of the distal pancreatic duct and a further accessory duct of the body of the pancreas draining into the main pancreatic duct were identified. The pancreatic tail presented normal size and morphology on axial imaging. This anomaly, not reported yet in the literature, can be categorized as a number of a duplication anomaly, in which the main pancreatic duct is trifurcated along its length. CONCLUSION Congenital anomalies of the pancreas and pancreatic duct are rare but not uncommonly detected on diagnostic imaging. MRI and MRCP are the non-invasive imaging modalities of choice for diagnosing congenital anomalies of the pancreas and the pancreatic duct.
