Vaccines in children with inflammatory bowel disease: Brief review

Incidence of inflammatory bowel diseases (IBDs), including Crohn’s disease (CD) and ulcerative colitis (UC), is increasing worldwide. Children with IBDs have a dysfunctional immune system and they are frequently treated with immunomodulating drugs and biological therapy, which significantly impair immune system functions and lead to an increased risk of infections. Vaccines are essential to prevent at least part of these infections and this explains why strict compliance to the immunization guidelines specifically prepared for IBD patients is strongly recommended. However, several factors might lead to insufficient immunization. In this paper, present knowledge on the use of vaccines in children with IBDs is discussed. Literature review showed that despite a lack of detailed quantification of the risk of infections in children with IBDs, these children might have infections more frequently than age-matched healthy subjects, and at least in some cases, these infections might be even more severe. Fortunately, most of these infections could be prevented when recommended schedules of immunization are carefully followed. Vaccines given to children with IBDs generally have adequate immunogenicity and safety. Attention must be paid to live attenuated vaccines that can be administered only to children without or with mild immune system function impairment. Vaccination of their caregivers is also recommended. Unfortunately, compliance to these recommendations is generally low and multidisciplinary educational programs to improve vaccination coverage must be planned, in order to protect children with IBD from vaccine-preventable diseases

Kinin B(1) receptor deficiency leads to leptin hypersensitivity and resistance to obesity

OBJECTIVE-Kinins mediate pathophysiological processes related to hypertension, pain, and inflammation through the activation of two G-protein-coupled receptors, named B(1) and B(2). Although these peptides have been related to glucose homeostasis, their effects on energy balance are still unknown.RESEARCH DESIGN and METHODS-Using genetic and pharmacological strategies to abrogate the kinin B(1) receptor in different animal models of obesity, here we present evidence of a novel role for kinins in the regulation of satiety and adiposity.RESULTS-Kinin B(1) receptor deficiency in mice (B(1)(-/-)) resulted in less fat content, hypoleptinemia, increased leptin sensitivity, and robust protection against high-fat diet-induced weight gain. Under high-fat diet, B(1)(-/-) also exhibited reduced food intake, improved lipid oxidation, and increased energy expenditure. Surprisingly, B(1) receptor deficiency was not able to decrease food intake and adiposity in obese mice lacking leptin (ob/ob-B(1)(-/-)). However, ob/ob-B(1)(-/-) mice were more responsive to the effects of exogenous leptin on body weight and food intake, suggesting that B(1) receptors may be dependent on leptin to display their metabolic roles. Finally, inhibition of weight gain and food intake by B(1) receptor ablation was pharmacologically confirmed by long-term administration of the kinin B(1) receptor antagonist SSR240612 to mice under high-fat diet.CONCLUSIONS-Our data suggest that kinin B(1) receptors participate in the regulation of the energy balance via a mechanism that could involve the modulation of leptin sensitivity.Universidade Federal de São Paulo, Dept Biophys, BR-04023062 São Paulo, BrazilUniv Mogi das Cruzes, Mogi Das Cruzes, BrazilUniversidade Federal de São Paulo, Dept Physiol, BR-04023062 São Paulo, BrazilSanofi Aventis, Montpellier, FranceUniversidade Federal de São Paulo, Dept Med, BR-04023062 São Paulo, BrazilInst Natl Sante & Rech Med, Dept Renal & Cardiac Remodeling, U858 I2MR, Toulouse, FranceUniv Toulouse 3, Inst Med Mol Rangueil, F-31062 Toulouse, FranceInst Natl Rech Agron AgroParisTech, UMR914 Nutr Physiol & Ingest Behav, Paris, FranceMax Delbruck Ctr Mol Med, Berlin, GermanyUniversidade Federal de São Paulo, Dept Biophys, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Physiol, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, Dept Med, BR-04023062 São Paulo, BrazilWeb of Scienc

Polyamide-Scorpion Cyclam Lexitropsins Selectively Bind AT-Rich DNA Independently of the Nature of the Coordinated Metal

Cyclam was attached to 1-, 2- and 3-pyrrole lexitropsins for the first time through a synthetically facile copper-catalyzed “click” reaction. The corresponding copper and zinc complexes were synthesized and characterized. The ligand and its complexes bound AT-rich DNA selectively over GC-rich DNA, and the thermodynamic profile of the binding was evaluated by isothermal titration calorimetry. The metal, encapsulated in a scorpion azamacrocyclic complex, did not affect the binding, which was dominated by the organic tail

A population-based study of injuries to the brachial plexus and to the peripheral nerves of the shoulder girdle and upper limb in the Italian region Friuli Venezia Giulia

The aim of this study was to estimate the incidence, identify the causes, and explore treatments of the injuries to the brachial plexus and peripheral nerves of the shoulder girdle and upper limb in the 1,220,000-inhabitant Italian region Friuli Venezia Giulia.We linked at the individual patient level various administrative databases using an anonymous stochastic key: list of residents, hospital discharge, emergency department, and outpatient care prescriptions database. We abstracted hospital discharge records with at least one discharge diagnosis code ICD-9-CM 953.4 (brachial plexus) or 955.0-955.9 (upper limb). For hospitalized patients, we investigated the prescriptions of ambulatory care during the following year. Emergency department visits in the month prior to hospital admission were also assessed.From 2000 to 2015, we observed 474 hospitalizations (annual average: 61); 48% of patients received at least one prescription of outpatient physical therapy and rehabilitation in the following year, accounting for more than 25,000 visits and interventions. According to emergency department data, falls were the most common mechanism among the elderly; cuts were common among the young.This is the first population study of peripheral nerve injuries to the brachial plexus and peripheral nerves of the shoulder girdle and upper limb in Italy

The diagnostic, therapeutic and assistance pathway for amyotrophic lateral sclerosis in a north-eastern Italian region: satisfaction of patients and their caregivers

In order to evaluate the users\u2019 satisfaction degree for the diagnostic, therapeutic and assistance services for amyotrophic lateral sclerosis (ALS) in the Italian region Friuli-Venezia Giulia (FVG), a self-compiled anonymous multiple-choice questionnaire was administered to ALS patients and their caregivers. The questionnaire explored 41 different issues covering the following areas: (a) access to diagnostic pathway and communication among patients, families and health professionals; (b) quality of disease monitoring and effectiveness of interventions aimed at mitigating ALS symptoms; (c) easiness of access to assistive devices (e.g. wheelchair, ankle-foot-orthosis) and home assistance; (d) patient\u2019 choices sharing and health professionals empathy. The same issues were proposed both to patients and carers, appropriately adapting the questions, during the period between June and December 2019. The answers were categorised according to criticality level. Median with interquartile range of the numeric variables and percentages of the categorical variables and of the answers to questions were calculated. The mean percentage of satisfied users was 72.8%, considering all the areas. Pain treatment and easiness of access to ambulance transport were the most positive aspects (95.7% and 92.5% of satisfied respondents, respectively), while information about possible enrolment in clinical trials and about possible registration to the regional ALS association were the most critical issues (30.9% and 43.4% of satisfied users). Although the satisfaction level of ALS patients and their caregivers for the services provided resulted generally good, there were some areas that have to be improved. For this purpose, enhancement of multidisciplinary collaboration, sharing of points of view from users and different practitioners and rising awareness among healthcare professionals through clinical audits could be useful. Further research is needed to identify a wider range of users\u2019 unexplored unmet needs

Hysteroscopic metroplasty with resectoscope or microscissors for the correction of septate uterus

During 1990, we performed hysteroscopic incision of uterine septum in 23 women with repeated abortion. The patients were allocated randomly to metroplasty with resectoscope (12 patients in group 1) or microscissors (11 patients in group 2) to compare surgical feasibility and anatomic results with these instruments. The uterine cavity was distended by instillation of sorbitol and mannitol solution under manometric control. Two patients in group 1 and three in group 2 had a complete septum. In group 1, the mean operating time, plus or minus standard deviation (S.D.), was 22 +/- 6 minutes compared with 17 +/- 5 minutes in group 2 (p = 0.06). The mean amount of distension medium used, plus or minus S.D., was 890 +/- 153 milliliters in group 1 versus 671 +/- 170 milliliters in group 2 (p = 0.003). One woman in group 1 with complete uterine septum had a uterine perforation that was managed conservatively. Postoperative morbidity for the entire series was negligible. At follow-up ultrasonography and hysteroscopy performed two months postoperatively, a residual fundal notch > or = 1 centimeter deep was detected and corrected in four patients in group 1 and two in group 2. Our findings indicate that, in terms of operating time and efficacy, the resectoscope and microscissors are equally valid instruments to correct a septate uterus, with a feasibility rate of 100 percent

Veralipride for hot flushes during gonadotropin-releasing hormone agonist treatment

Hot flushes are the commonest symptom induced by gonadotropin-releasing hormone agonists (GnRHa). We performed an open observational trial to evaluate the efficacy of veralipride, an antidopaminergic drug, in reducing hot flushes in 25 premenopausal women treated with a GnRHa for endometriosis (8 subjects) or menorrhagia (17 subjects). The patients received goserelin depot for 6 months and veralipride was added for the third month. Hot flushes, severe in all women at 2 months, improved in both frequency and intensity in 92 % of the subjects during veralipride administration. The benefit obtained persisted until the end of the GnRHa treatment

By-catch of franciscana Pontoporia blainvillei in Uruguayan artisanal gillnet fisheries: an evaluation after a twelve-year gap in data collection

The franciscana dolphin (Pontoporia blainvillei) is the most threatened small cetacean in the southwestern Atlantic Ocean. Its incidental capture in the Uruguayan fisheries of the Atlantic oceanic coast (AOC) has been recorded since 1940 and was systematically studied from 1974 to 1994, providing the most recent by-catch per unit of effort estimate (BPUE) for the AOC region (0.0064 franciscanas per 1000m net per fishing set). The lack of new by-catch data during the past 12 years has led to a data gap in by-catch estimates for the species in Uruguay. The current study was developed in two separate stages, a first stage (July 2004 - December 2005) designed to identify fisheries that interact with franciscana, and a second stage (2006), designed to determine new BPUE and franciscana mortality estimates for the selected fisheries. During the first stage, 13 artisanal fisheries of the Uruguayan coast were visited monthly, while in the second stage five fisheries (including the Rio de la Plata estuary and the AOC) were selected for monitoring. During 2006, 26 fishermen recorded all the information related to each fishing event, allowing the estimation of fishing effort calculated in linear units multiplied by hour (FEL). We also estimated a fishing set (FES) based by-catch rate which allowed the comparison with previously reported results. For 2006, the BPUEL (based on FEL) was estimated at 0.0020 franciscanas per 1000m net per hour and the BPUES at 0.0286 franciscanas per 1000m net per fishing set. The BPUEL was extrapolated to the surveyed fishing fleets during 2006, resulting in a mortality estimate of 289 (95% CI: 266-350) franciscanas. Based on the fishing dynamics reported herein, we consider the BPUEL the most accurate estimate of by-catch for the Uruguayan coast. This research updates the values of BPUE in the AOC after a 12-year information gap and includes the first by-catch evaluation in the Uruguayan estuarine coast. We highly recommend an abundance estimation of the species to complement the information reported herein in order to know the current status of franciscana dolphin population in Uruguay
