Aim: This study aims to evaluate the impact of frailty on the outcomes of older patients with pulmonary embolism (PE)., Methods: Using the National Inpatient Sample database, we identified 288 070 patients aged 65 or older who were admitted with a primary diagnosis of PE from 2017 to 2019. Frailty was assessed using the Hospital Frailty Risk Score (HFRS), and patients were categorized into low-, intermediate-, and high-frailty-risk groups. Multivariate logistic regression was used to calculate adjusted odds ratios for all outcomes., Results: These patients were categorized into low-risk (57.6%, 161 420), medium-risk (39.9%, 111 805), and high-risk (2.5%, 7075) groups. High-risk patients, predominantly females with multiple comorbidities, exhibited significantly higher mortality rates and adverse outcomes. The HFRS showed a good discriminating ability in predicting mortality (area under the receiver operating characteristic curve = 0.7796). Frailty was associated with increased use of advanced therapeutic interventions and critical care resources such as thrombolysis, catheter-directed therapies, inferior vena cava filter placement, mechanical ventilation, vasopressor use, and intensive care unit admission., Conclusion: Frailty markedly affects outcomes in older PE patients. The HFRS offers a valuable prognostic tool in this population, suggesting that integrating frailty assessments into clinical practice could enhance care strategies and improve patient outcomes. Our findings underscore the need for further research to refine frailty-based care paradigms. Geriatr Gerontol Int 2024; ••: ••-••., (© 2024 Japan Geriatrics Society.)

Objective To examine stigmatizing attitudes towards people with mental disorders among primary care professionals and to identify potential factors related to stigmatizing attitudes through a systematic review. Methods A systematic literature search was conducted in Medline, Lilacs, IBECS, Index Psicologia, CUMED, MedCarib, Sec. Est. Saúde SP, WHOLIS, Hanseníase, LIS-Localizador de Informação em Saúde, PAHO, CVSO-Regional, and Latindex, through the Virtual Health Library portal ( http://www.bireme.br website) through to June 2017. The articles included in the review were summarized through a narrative synthesis. Results After applying eligibility criteria, 11 articles, out of 19.109 references identified, were included in the review. Primary care physicians do present stigmatizing attitudes towards patients with mental disorders and show more negative attitudes towards patients with schizophrenia than towards those with depression. Older and more experience doctors have more stigmatizing attitudes towards people with mental illness compared with younger and less-experienced doctors. Health-care providers who endorse more stigmatizing attitudes towards mental illness were likely to be more pessimistic about the patient's adherence to treatment. Conclusions Stigmatizing attitudes towards people with mental disorders are common among physicians in primary care settings, particularly among older and more experienced doctors. Stigmatizing attitudes can act as an important barrier for patients to receive the treatment they need. The primary care physicians feel they need better preparation, training, and information to deal with and to treat mental illness, such as a user friendly and pragmatic classification system that addresses the high prevalence of mental disorders in primary care and community settings.

During the last twenty years Eosinophilic Esophagitis has become one the most important causes of esophageal disfunction in children, food impactation in adolescents and young adults, therapeutic failure in patients with gastroesophageal reflux disease (GERD) and the most frecuent eosinophilic disease of the gastrointestinal tract. We present recommendations for the diagnosis and treatment of the disease based in a systematic review of the literature.

Objective: In early infancy, various gastrointestinal symptoms (e.g., constipation, regurgitation, crying/fussiness, infantile colic, and excessive gas) are common problems and may result in numerous visits to pediatricians. Worldwide, this often results in switching infant formulas because parents (and sometimes doctors) believe these symptoms reflect a formula intolerance. However, in many cases, these infants are growing and developing normally. This study was performed to offer family pediatricians consensus-based algorithms on the management of the most common gastrointestinal symptoms in infants., Methods: A group of pediatric gastroenterologists and pediatric allergists from Europe, USA, Latin America, and Asia developed guidelines and practical algorithms to assist general pediatricians in addressing this challenge., Results: Five such practice recommendations were developed after a thorough literature review. These algorithms should not be considered as an "evidence-based guideline"; on the contrary, the authors are convinced that challenging these proposals will result in updated and improved versions., Conclusion: To date, these algorithms, based on the published literature, are the result of a broad consensus of pediatric gastroenterologists from different continents., (Copyright © 2013 Elsevier Inc.

Palytoxin is one of the most complex and biggest molecules known to show extreme acute toxicity. The dinoflagellate Ostreopsis spp., the producer organism of palytoxin, has been shown to be distributed worldwide, thus making palytoxin an emerging toxin. Rat-derived hepatocytes (Clone 9) and BE (2)-M17 human neuroblastoma cells were used to test palytoxin or palytoxin-like compounds by measuring the cell metabolic rate with Alamar Blue. The dose-dependent decrease in viability was specifically inhibited by ouabain in the case of BE (2)-M17 neuroblastoma cells. This is a functional, dynamic and simple test for palytoxins with high sensitivity (as low as 0.2 ng/ml). This method was useful for toxin detection in Ostreopsis extracts and naturally contaminated mussel samples. A comparative study testing toxic mussel extracts by LC (liquid chromatography)-MS/MS (tandem MS), MBA (mouse bioassay), haemolysis neutralization assay and a cytotoxicity test indicated that our method is suitable for the routine determination and monitoring of palytoxins and palytoxin-like compounds.

Background and Purpose: Dinoflagellates from the genus Ostreopsis have been related to the production of palytoxin and analogues. Based on that, this paper describes functional studies of crude extracts from Ostreopsis cf. siamensis collected in the Mediterranean Sea in order to biochemically characterize their toxic compounds., Methods: We compared the effects of 5 crude dinoflagellates extracts with a commercially available palytoxin and a purified Ostreopsis ovata extract on metabolic activity, membrane potential, and cytosolic calcium levels by using fluorescent dyes., Results: All the extracts resulted to be neurotoxic. In addition, all of them induced a membrane depolarization and a calcium increment that were abolished when preincubating with ouabain, an inhibitor of the Na(+)/K(+) pump., Conclusion: The effects observed were quite close to those induced by palytoxin and the Ostreopsis ovata extract as well, suggesting that Ostreopsis cf. siamensis is actually producing palytoxin-like compounds that are highly toxic and functionally active., (Copyright 2009 S.

Background: The exact cause of recurrent pancreatitis among patients with anomalous pancreaticobiliary union is not known. Sphincter of Oddi dysfunction has been implicated as a mechanism. This study evaluated sphincter of Oddi function in children with anomalous pancreaticobiliary union and recurrent pancreatitis and assessed the results of endoscopic sphincterotomy in the management of this condition., Methods: We retrospectively reviewed 128 endoscopic retrograde cholangiopancreatographic (ERCP) studies performed on children older than 1 year and adolescents with pancreaticobiliary disease. In 64 instances, ERCP was performed because of recurrent pancreatitis. Nine patients underwent sphincter of Oddi manometry followed by endoscopic sphincterotomy, and these patients were included in this study. A basal pressure greater than 35 mm Hg was considered diagnostic for sphincter of Oddi dysfunction. Follow-up data were obtained retrospectively from the patients' relatives and referring physicians., Results: An anomalous pancreaticobiliary union was found in 18 of 64 (28%) patients with recurrent pancreatitis. The 9 patients who underwent sphincter manometry and endoscopic sphincterotomy were 5 girls and 4 boys 2.9 to 17 years of age (mean 7.8 years). A choledochal cyst was found in 7 of these 9 patients. Two patients had anomalous pancreaticobiliary union without common bile duct dilatation. All 9 patients had sphincter of Oddi dysfunction (mean basal pressure 96 +/- 37.8 mm Hg, range 48 to 156 mm Hg). The length of the common channel was 22.8 +/- 5.5 mm, and the length of the sphincter of Oddi segment was 12.1 +/- 1.9 mm (p < 0.001). In all patients the sphincter of Oddi segment was located within the duodenal wall. The mean follow-up period after endoscopic sphincterotomy was 26.4 months (range 18 to 38 months). Eight patients had excellent results defined as absence of symptoms and no subsequent episodes of acute pancreatitis. Treatment of 1 patient was considered moderately successful because the patient still had occasional pain without pancreatic enzyme elevation but no subsequent episodes of acute pancreatitis. One patient had mild postprocedural pancreatitis., Conclusions: Recurrent pancreatitis and anomalous pancreaticobiliary union are associated with sphincter of Oddi dysfunction in children and adolescents. Endoscopic sphincterotomy is beneficial to these patients.

Anorectal manometry is a non invasive, safe and useful procedure for exploring anorectal function in several disease. The anorectal studies made in our service the last five years in children, were reviewed. There were made 234 procedures in patients 21 year old or less 93.25% of the studies could be finished and 72.64% of the patients were from other hospitals or centers. The age average was 5.62 +/- 4.72 years and the main indication was constipation (78.20%). We didn't find any statistical difference in the manometrical findings of the internal anal sphincter between the patients with only constipation, only encopresis, constipation plus encopresis and normal values. The main manometrical diagnostic in the constipated patient without Hirschsprung disease was "Normal Study" even though between 30 and 55% of the studies showed "inspecific motor dysfunction". The patients with anorectal malformations had a main internal and pressure statistically lower (Z = 3.29 p = 0.03) and "Non concluyent Study" percentage higher (Z03.44 p = 0.02) than the constipated ones. The main external anal pressure was not different between groups. In 43 patients the manometrical study showed "Suggestive of Hirschsprung Disease". We recovered the histological reports in 55.88% with aganglionosis in the 91.66%. There were no statistical differences in the other manometrical parameters. Our finding agree with the ones reported in the specialized literature and support the anorectal manometry as an useful tool for exploring the anal sphincter integrity in anorectal malformations.

We studied the effect of Cisapride (10 mg vo every 8 hours) on the characteristics of the evacuations, orocoecal transit time and motility trough rectoanal manometry in patients diagnosed with chronic constipation. The patients (N = 51) received placebo and/or drug in a controlled, randomized, double blind, crossed study during two treatment phases of 30 days each. The end of each phase was followed by a clinical evaluation, a rectoanal manometry and hydrogen breath test. Cisapride increased the rhythm of ecacuations (5.53 days +/- 3.11 vs 1.59 days +/- 1.15 p < 0.05) improved the frequency of evacuations and diminished the consistency of the feces (p < 0.05), shortened the orocoecal transit time (271.57 min +/- 9.87 vs 201.18 min +/- 29.30 p < 0.05) and improved the parameters of the rectoanal manometry readings such as the pressure of internal anal sphincter (58.14 mmHg 7.33 vs 53.90 mmHg 5.19 p < 0.05), and its relaxation percentage (73.41% +/- 15.30 vs 66.84% +/- 11.83 p < 0.05). Side effects associated with Cisapride were not significant. It is concluded that Cisapride improves intestinal motility in chronic constipation.

ERCP was performed in 51 patients, aged 1 to 18 years, as part of diagnostic evaluation for recurrent pancreatitis without obvious cause or as therapeutic intervention. ERCP was successful in 50 patients (98%). Thirty-four patients (68%) had anatomic findings indicating a possible cause of recurrent pancreatitis. Three patients (6%) had findings suggestive of sphincter of Oddi dysfunction. Eighteen of the 37 patients (49%) with ductal abnormalities underwent endoscopic therapy, with a favorable outcome in 15 (83%). Eleven patients were treated surgically, and 8 of these patients (73%) improved symptomatically. Eight patients received no treatment, and 6 of them (67%) had recurrent bouts of clinical pancreatitis. One mild case of pancreatitis (1.9%) occurred after ERCP, and 3 mild cases followed endoscopic therapy. In conclusion, ERCP is a relatively safe technique that produces opacification of the desired ductal system with a high degree of accuracy and provides useful information in the evaluation of children with idiopathic recurrent pancreatitis. These data suggest that endoscopic pancreatic therapy may result in symptomatic improvement, eliminating the need for surgery in selected children. Furthermore, the study demonstrates that manipulation of the pancreatic duct is comparatively safe and less hazardous than formerly believed.

ERCP was performed in two infants (29 and 62 days old) and eight children (5 to 12 years old) with jaundice due to common bile duct stones. Seven patients had hemolytic anemia and three patients had a family history of gallstone disease. Successful cannulation of the common bile duct demonstrating stones was accomplished in all patients. Four patients had coexisting gallstones and were treated surgically. Six children who had previously undergone cholecystectomy were treated by endoscopic sphincterotomy and stone extraction without complication. We believe that ERCP should be utilized by expert endoscopists in children with evidence of extra-hepatic cholestasis, and endoscopic sphincterotomy should be the treatment of choice in children who have previously undergone cholecystectomy, and who are jaundiced secondary to common bile duct stones.

This study assessed the usefulness of ERCP in the diagnosis of biliary atresia. We evaluated 57 infants with prolonged cholestasis with abdominal ultrasound, liver biopsy, and ERCP. Using clinical observations alone, 22 infants were thought to have biliary atresia; whereas 35 children were thought to have neonatal hepatitis. The ERCP was performed with a prototype duodenoscope and was successful in all infants except two with biliary atresia. In 20 infants three types of radiological findings consistent with biliary atresia were seen: type 1, no visualization of biliary tree (35%); type 2, opacification of the distal common duct and gallbladder without visualization of the main hepatic duct (35%); and type 3, opacification of the distal common duct, the gallbladder, and a segment of the main hepatic duct with biliary lakes at the porta hepatis (30%). Twenty-five of 35 infants with suspected neonatal hepatitis were excluded because of a liver biopsy that was diagnostic. In the remaining 10 infants the liver biopsy had some features of extrahepatic biliary atresia and ERCP was performed prior to surgery. A normal extrahepatic biliary tree was obtained in all of them. In conclusion, ERCP permits the visualization of the biliary tree in young infants and is useful in selecting those infants who should be considered for exploratory laparotomy.

The usefulness of a new pediatric duodenoscope PJF in the diagnosis of neonatal cholestasis was studied in 23 infants with ages ranging from 19 to 150 days. In 22 of 23 infants the papilla was cannulated. In 13 of 14 neonates (93%) with neonatal hepatitis, the common bile duct was opacified and biliary atresia was excluded. In one of two neonates with choledochal cyst, the common bile duct was demonstrated. In six of seven neonates (86%) with biliary atresia, only the pancreatic duct was demonstrated and the diagnosis was suspected. Although absence of a common bile duct opacification does not rule out biliary atresia, ERCP with the new duodenoscope proved to be most useful in the diagnosis of normal biliary tree and served to avoid unnecessary surgery in most infants with neonatal cholestasis.
