RESUMO

Systemic steroid exposure, while useful for the treatment of acute flares in inflammatory bowel disease (IBD), is associated with an array of side effects that are particularly significant in children. Technical advancements have enabled locoregional intraarterial steroid delivery directly into specific segments of the gastrointestinal tract, thereby maximizing tissue concentration while limiting systemic exposure. We investigated the feasibility of intraarterial steroid administration into the bowel in a cohort of nine pediatric patients who had IBD. This treatment approach provided symptom relief in all patients, with sustained relief (>2 weeks) in seven out of nine; no serious adverse effects occurred in any patient. In addition, we identified patterns of vascular morphologic changes indicative of a vasculopathy within the mesenteric circulation of inflamed segments of the bowel in pediatric patients with Crohn's disease, which correlated with disease activity. An analysis of publicly available transcriptomic studies identified vasculitis-associated molecular pathways activated in the endothelial cells of patients with active Crohn's disease, suggesting a possible shared transcriptional program between vasculitis and IBD. Intraarterial corticosteroid treatment is safe and has the potential to be widely accepted as a locoregional approach for therapy delivery directly into the bowel; however, this approach still warrants further consideration as a short-term "bridge" between therapy transitions for symptomatic IBD patients with refractory disease, as part of a broader steroid-minimizing treatment strategy.

RESUMO

RATIONALE: Obesity is a major health problem worldwide. An understanding of the factors that drive feeding behaviors is key to the development of pharmaceuticals to decrease appetite and consumption. Proopiomelanocortin (POMC), the melanocortin peptide precursor, is essential in the regulation of body weight and ingestive behaviors. Deletion of POMC or impairment of melanocortin signaling in the brain results in hyperphagic obesity. Neurons in the hypothalamic arcuate nucleus produce POMC and project to many areas including the nucleus accumbens (NAcc), which is well established in the rewarding and reinforcing effects of both food and drugs of abuse. OBJECTIVE: These studies sought to determine the role of melanocortins in the NAcc on consumption of and motivation to obtain access to standard rodent chow. METHODS: Male, C57BL/6J mice were microinjected bilaterally into the NAcc (100 nl/side) with the melanocortin receptor 3/4 agonist melanotan-II (MT-II; 0.1, 0.3, and 1 nmol), and ingestive behaviors were examined in both home cage and operant food self-administration experiments. In addition, the ability of MT-II in the NAcc to produce aversive properties or affect metabolic rate were tested. RESULTS: MT-II injected into the NAcc significantly decreased consumption in both home cage and operant paradigms, and furthermore decreased appetitive responding to gain access to food. There was no development of conditioned taste avoidance or change in metabolic parameters following anorexic doses of MT-II. CONCLUSIONS: MT-II in the NAcc decreased both the motivation to eat and the amount of food consumed without inducing an aversive state or affecting metabolic rate, suggesting a role for melanocortin signaling in the NAcc that is selective for appetite and satiety without affecting metabolism or producing an aversive state.

RESUMO

PURPOSE: To review safety and efficacy of bronchial artery embolization (BAE) for treatment of hemoptysis in adult patients with cystic fibrosis (CF) and to report 30-day, 1-year, and 3-year outcomes. MATERIALS AND METHODS: Between January 2001 and April 2018, 242 patients with CF were evaluated for hemoptysis. Thirty-eight BAEs were performed in 28 patients with hemoptysis. Technical success was defined as freedom from repeat embolization and hemoptysis-related mortality. Clinical success was defined as freedom from repeat embolization and mortality from any cause. Technical and clinical success were examined at 30 days, 1 year, and 3 years after initial BAE. Mean patient age was 32 years, and median follow-up was 4.8 years (range, 10 mo to 16.7 y). RESULTS: Technical and clinical success rates at 30 days were 89% (25/28) and 82% (23/28), respectively. Success rates at 1 year were 86% (24/28) and 79% (22/28), respectively, and at 3 years were 82% (23/28) and 75% (21/28), respectively. The 30-day overall complication rate was 7.9% (3/38) with 2.6% (1/38) major complication rate and 5.2% (2/38) minor complication rate. Overall 3-year mortality rate was 25% (7/28). CONCLUSIONS: BAE is safe and effective in patients with CF presenting with life-threatening hemoptysis. BAE results in high rates of long-term technical and clinical success in this patient population despite progressive chronic disease. Repeat embolization is necessary only in a minority of patients.

RESUMO

BACKGROUND: Sydney Sexual Health Centre (SSHC) Xpress clinic has significantly reduced the length of stay and waiting time for clients at SSHC but is currently only available to clients who can read and understand a high level of English. This reduces access for culturally and linguistically diverse (CALD) clients. This study sought to determine the acceptability of 4 proposed components of an express clinic model among CALD clients: computer-assisted self-interview (CASI), self-collection of swabs/urine specimens, not having a physical examination, and consultation with a health promotion officer rather than with a clinician. Differences in acceptability based on language group, new or return client status, sex worker status, clinic visited status, and age were analyzed. METHODS: A cross-sectional, anonymous questionnaire was offered to all female Chinese, Thai, and Korean clients attending SSHC between March and November 2012. Multivariate regression and Pearson χ statistical analyses were conducted using STATA 12 software. RESULTS: A total of 366 questionnaires were returned from 149 Thai, 145 Chinese, and 72 Korean participants. After multivariate analysis, the only predictor of willingness to use an express model of service provision was language group: overall, 67% Thai (odds ratio, 3.74: confidence interval [CI], 2.03-6.89; P < 0.01) and 64% Korean (odds ratio, 3.58; CI, 1.77-7.25, P < 0.01) said that they would use it compared with 35% Chinese. Age, history of sex work, new or returning clients, and general or language clinic attendance did not impact on choices. Within the preference for individual components of the model, more Thai women were happy with using a health promotion officer (43.2%) than Chinese (14.1%) or Korean (8.5%) (P < 0.001); no groups were happy with forfeiting a physical examination; Thai (48.6%) and Korean (40.9%) were happier with self-swabbing than Chinese women (23.9%, P < 0.001); and more Thai were happy to use a CASI (44.2%) than Chinese (12%) or Korean (11.1%; P < 0.001). CONCLUSIONS: This research shows that the components of an express model used at SSHC are not favorable to our CALD client base. Despite a CALD express clinic having the potential to reduce waiting times, most clients did not favor reduced waiting time over being physically examined or using a CASI.

RESUMO

Given the documented benefits of using text messaging (short message service; SMS), the internet and email to deliver sexually transmissible infection (STI) test results, including high acceptability among clients, Sydney Sexual Health Centre (SSHC) aimed to identify which methods our clients preferred for receiving their results, using a cross-sectional survey. There was a preference for SMS (32%) for negative STI results, and for SMS (27%), phone call (27%) and in-person (26%) for negative HIV results. An in-person preference was shown for receiving positive STI results (40%) and positive HIV results (56%, P<0.001). While many clients would prefer to receive STI test results via text messages or phone call, many also still prefer a return visit, with this preference is dependent on the type and nature of the results. Our study suggests that, ideally, several options for obtaining results should be available.

RESUMO

Sydney Sexual Health Centre (SSHC) and the NSW Users and AIDS Association (NUAA), the NSW peer-based drug user organisation, pilot tested an outreach sexually transmissible infection (STI) testing station using self-collected urine and swabs in NUAA's needle and syringe program (NSP) space. The model was based on SSHC's established Xpress clinic. A needs assessment among NUAA clients was undertaken prior to commencement in order to ascertain potential uptake. A computer-assisted self interview was developed with data securely transferred to SSHC daily. During the 6 months from January to July 2011, almost 3000 occasions of service were recorded in the NSP from an estimated 375 clients. Four clients took advantage of NUAA Xpress during this time. Despite initial client interest, promotional efforts and the success of this methodology elsewhere, this outreach model did not have a successful uptake and was discontinued. This project provides value in considering the methodology and implementation of future outreach STI testing projects for people who inject drugs.

RESUMO

BACKGROUND: Sydney Sexual Health Centre (SSHC) commenced a fast-track sexually transmissible infection clinic, the Xpress Clinic (Xpress) pilot for asymptomatic clients in March 2010, using a computer-assisted self-interview and self-collected samples. This study examines client satisfaction and changes in intended screening frequency among clients of Xpress. METHODS: This was a cross-sectional study of all clients attending Xpress clinics during the initial 6 months. All clients were requested to complete a survey based on a previously validated questionnaire. Results were stratified by sex, sex of sexual partners, age, and sex work status. RESULTS: Of the 243 clients who attended Xpress, 145 (60%) returned questionnaires. The 2 most common reasons for choosing Xpress clinic were reduced waiting time (n = 42/138 [30%]; 95% confidence interval [CI], 23%-38%) and reduced length of consultation (n = 16/138 [12%]; 95% CI, 7%-17%).When asked if they would have come to SSHC anyway if Xpress was not an option, men who have sex with men (MSM) were more likely than non-MSM to say that they would come for screening anyway (77% MSM vs. 59% non-MSM, P = 0.034). Youth younger than 25 were less likely than those 25 years and older to have come for screening anyway (53% vs. 79%, P = 0.012).Most (n = 101/138 [73%]; 95% CI, 65%-80%) considered that they would test for sexually transmissible infections more frequently in the future using the Xpress model. Client satisfaction levels were high, with most respondents reporting that they would return to Xpress (n = 119/142 [83%]; 95% CI, 77%-89%) and would recommend it to friends (n = 122/142 [86%]; 95% CI, 79%-90%). CONCLUSIONS: Most clients were highly satisfied with all aspects of Xpress and reported intentions to retest using this model of care.

RESUMO

BACKGROUND: The present study aimed to ascertain the acceptability to at-risk young people of self-collected urine samples as a means of testing for Chlamydia trachomatis (chlamydia); to determine the effectiveness of drop-off and outreach collection methods as a means of detecting and treating chlamydia; and to determine the rate of positive chlamydia tests in a sample of the target group. METHODS: Participants requested postal testing kits from the project website, the NSW Sexual Health Infoline or at an outreach event and either returned urine samples at selected drop-off locations or directly to the researchers during active outreach events. RESULTS: A total of 413 kits were requested - 196 (47.5%) via email, 204 (49.4%) during outreach events and nine (2.2%) via the NSW Sexual Health Infoline. A total of 195 samples (47.2% of ordered kits) were returned. Participants were less likely to return samples if they had been requested by email (odds ratio = 9.6; 95% confidence interval: 6.0-15.0) or via telephone (odds ratio = 22.0; 95% confidence interval: 2.7-181.0) compared with directly obtaining a kit at an outreach event. The number of specimens positive for chlamydia in the targeted age range was 4, giving a 3.1% positive rate (95% confidence interval: 1.0-8.0). CONCLUSIONS: This study identified that free testing kits and online communication worked well as a means of engaging young people and raising awareness of sexual health. However, the requirement to drop-off urine samples at selected locations was not well accepted.
