RESUMO

OBJECTIVES: A population-based physical activity (PA) programme was implemented to increase PA levels and encourage individuals to join the local council leisure facility. STUDY DESIGN: This is a cross-sectional design. METHODS: The 6-week programme Summer of Sport (SOS) involved a total of 487 individuals registered for PA sessions. The sessions were held at three local council leisure facilities included badminton, swimming, table tennis, squash and group cycle. The programme was assessed using a survey based on the Theory of Planned Behaviour. Individuals were asked for their current fitness levels, whether the programme encouraged them to be more active and for their intentions to join the leisure centre after the programme. RESULTS: Of the 487 who originally registered for the programme, there were 161 users of SOS, with 112 not already members of the leisure facility. After the programme, 83% considered themselves already being active, with 78% stating that they partook in at least 30 min of exercise, 3 times per week. Although a large proportion of individuals were already physically active, 78% stated that taking part encouraged them to become more active. More than half suggested that they would not join the leisure facility, 30% said that they had joined after the programme and 17% stated their intention to join. Many individuals highlighted that the programme provided an opportunity to be active with their family. CONCLUSIONS: Public health teams should work with partner organisations to embed robust processes for measuring outcomes that impact on population health.

RESUMO

Risky paternal alcohol use is associated with maternal alcohol use during pregnancy, poor fetal and infant outcomes, domestic violence and depression. This study developed 30 SMS text messages about alcohol for fathers who drink at risky levels. The text messages were developed using two motivational styles: messages presented in a second person voice and the same messages presented in a child's voice. Fifty-one fathers were recruited through social media to complete an online survey rating the SMS text messages for message importance and likelihood of seeking further information and measuring risky alcohol use and psychosocial distress. Seventeen participants then participated in a semi-structured qualitative interview. Fathers rated the text messages presented in the child's voice as more important than messages presented in the second person. Qualitative data supported survey results that motivational SMS text messages could provide an acceptable way to raise awareness of risky alcohol consumption for future fathers.

RESUMO

Dense (>96% theoretical) strontium titanate ceramics were fabricated at 950 °C (conventional sintering temperature > 1400 °C) using a reactive intermediate phase cold sintering process. An aqueous solution of SrCl2 mixed with TiO2 nanoparticles was added to SrTiO3 powders and pressed at 180 °C to obtain a highly compacted green body. During the post-press heating step at 950 °C, the TiO2 and SrCl2 create in-filling micro-reactions around each grain resulting in dense (>96%) SrTiO3 ceramics. Nano- and micron-sized starting powders were used, demonstrating that this reactive intermediate phase cold sintering route can densify a wide range of starting powder sizes, as it not reliant on an amorphous-to-crystalline precipitation through the terrace ledge kink mechanism, as has been identified repeatedly in previous cold sintering mechanisms. Moreover, this process has the potential to densify a wide variety of functional oxides, as a range of different low-temperature chemical synthesis routes could be used.

RESUMO

BACKGROUND: Depression and binge drinking behaviours are common clinical problems, which cause substantial functional, economic and health impacts. These conditions peak in young adulthood, and commonly co-occur. Comorbid depression and binge drinking are undertreated in young people, who are reluctant to seek help via traditional pathways to care. The iTreAD project (internet Treatment for Alcohol and Depression) aims to provide and evaluate internet-delivered monitoring and treatment programs for young people with depression and binge drinking concerns. METHODS: Three hundred sixty nine participants will be recruited to the trial, and will be aged 18-30 years will be eligible for the study if they report current symptoms of depression (score 5 or more on the depression subscale of the Depression Anxiety Stress Scale) and concurrent binge drinking practices (5 or more standard drinks at least twice in the prior month). Following screening and online baseline assessment, participants are randomised to: (a) online monthly self-assessments, (b) online monthly self-assessments + 12-months of access to a 4 week online automated cognitive behaviour therapy program for binge drinking and depression (DEAL); or (c) online monthly assessment + DEAL + 12-months of access to a social networking site (Breathing Space). Independent, blind follow-up assessments occur at 26, 39, 52 and 64-weeks post-baseline. DISCUSSION: The iTreAD project is the first randomised controlled trial combining online cognitive behaviour therapy, social networking and online monitoring for young people reporting concerns with depression and binge drinking. These treatments represent low-cost, wide-reach youth-appropriate treatment, which will have significantly public health implications for service design, delivery and health policy for this important age group. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry ACTRN12614000310662. Date registered 24 March 2014.

RESUMO

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) is a safe and effective single-stage treatment for choledocholithiasis in the elective setting. The outcomes after LCBDE in the emergency setting are unknown. The aim of this study was to compare the outcomes following elective and emergency LCBDE for choledocholithiasis. METHODS: Details of all patients who underwent LCBDE for choledocholithiasis between August 2003 and August 2013 were analysed retrospectively. The primary outcome measure was common bile duct (CBD) stone clearance rate. Secondary outcome measures were conversion rate, morbidity, mortality and length of hospital stay. RESULTS: Some 215 consecutive patients (57 male; median age 65 (range 14-92) years) underwent LCBDE. Some 121 procedures were performed electively and 94 as an emergency. Forty-five patients (48 per cent) presented with obstructive jaundice or cholangitis in the emergency LCBDE group compared with 15 (12·4 per cent) in the elective group (P < 0·001). The CBD stone clearance rate was similarly high in both groups (96 versus 96·7 per cent respectively; P = 0·557). There were no significant differences in conversion rate (6 versus 4·1 per cent), morbidity (5 versus 6·6 per cent), mortality (2 versus 0 per cent) or median length of stay (3 days) between groups. Two patients died, both following emergency LCBDE. CONCLUSION: LCBDE can be performed safely and effectively in both elective and emergency settings.

RESUMO

OBJECTIVE: Excessive alcohol consumption is common among people with psychotic disorders. While there is an extensive literature on the efficacy of psychological treatments for excessive drinking, few studies have examined interventions addressing this issue among people with psychotic disorders. METHOD: Systematic searches in PubMed and PsycINFO were conducted to identify randomized controlled trials comparing manual-guided psychological interventions for excessive alcohol consumption among individuals with psychotic disorders. Of the 429 articles identified, seven met inclusion criteria. Data were extracted from each study regarding study sample characteristics, design, results, clinical significance of alcohol consumption results, and methodological limitations. RESULTS: Assessment interviews, brief motivational interventions, and lengthier cognitive behavior therapy have been associated with reductions in alcohol consumption among people with psychosis. While brief interventions (i.e. 1-2 sessions) were generally as effective as longer duration psychological interventions (i.e. 10 sessions) for reducing alcohol consumption, longer interventions provided additional benefits for depression, functioning, and other alcohol outcomes. CONCLUSION: Excessive alcohol consumption among people with psychotic disorders is responsive to psychological interventions. It is imperative that such approaches are integrated within standard care for people with psychosis.

RESUMO

OBJECTIVE: To develop effective interventions for people with coexisting mental disorders (MD) and substance use, it may be beneficial to understand their attitudes and perceptions of substances. METHOD: A systematic literature search regarding attitudes and perceptions towards tobacco, alcohol or cannabis among people with MD was conducted. Studies' methodological quality was assessed using the Newcastle-Ottawa Scale. RESULTS: Twenty-one papers were included in the review and found to have generally low methodological quality. Papers investigated reasons for substance use, substance use expectancies, substances' perceived effects and reasons for quitting. People with psychotic disorders reported using substances primarily for relaxation and pleasure. Among people with mood disorders, alcohol was used primarily for social motives and tobacco for negative affect reduction. CONCLUSION: For substance use interventions among people with MD to be more effective, it may be necessary to tailor interventions specifically for this population and customize by substance type. Gaps in the literature regarding attitudes and perceptions towards substance use among people with MD were identified, which future research should aim to address. These include designing and conducting methodologically rigorous research, investigating perceived harmfulness and knowledge of substances, and broadening recruitment of participants to include people with MD other than psychosis.

RESUMO

BACKGROUND: Cross-sectional studies support an association between depression and inflammatory markers. However, little is known of their relationship in the context of antidepressant treatment. Our aim was to explore via meta-analysis whether antidepressant treatment is associated with a reduction in three inflammatory markers associated with depression. METHOD: A computerized search of EMBASE, Medline, PsycINFO and Cochrane Library databases was completed using subject headings for depression and either interleukin-6, C-reactive protein or interleukin-10, selecting studies which reported circulating levels of inflammatory markers before and after antidepressant treatment for people with depression. Outcome and moderator variables were coded for analysis, including inflammatory marker change, depression severity change, age, gender ratio, assay brand, treatment response and weight change. RESULTS: Pooled effect sizes showed a significant decrease in interleukin-6 (n=14, d=-0.42, p=0.02), marginally significant decrease in C-reactive protein (n=8, d=-0.57, p=0.05) and a non-significant decrease in interleukin-10 (n=3, d=-0.45, p=0.14) after treatment. High levels of heterogeneity were observed, which may be associated with clinical variations between the studies such as weight gain, anxiety, incomplete remission and other individual differences and co-morbidities. CONCLUSIONS: The findings of this meta-analysis indicate that there may be a normalization of overactive inflammatory processes following antidepressant treatment.

RESUMO

INTRODUCTION: The aim of this study was the assessment of patient outcome, peri-operative complications, length of stay and duration of operation after laparoscopic primary closure of the common bile duct (CBD) compared with choledochotomy with T-tube drainage and trans-cystic exploration. PATIENTS AND METHODS: Analysis of prospectively collected data on 71 explorations of the common bile duct between July 2001 and March 2006. RESULTS: A total of 71 patients had exploration of the CBD. Within this group, 12 were referred after failed endoscopic retro-grade cholangiopancreatography (ERCP). The methods of exploration included trans-cystic (9 cases), choledochotomy with T-tube (12), and choledochotomy with primary closure (50). CBD stones were found in 66 patients. In the remaining cases, we found a stricture in 1, debris in 2, and dilatation of the CBD without a stone in 2. There were 5 conversions to open technique and 3 patients required postoperative ERCP (1 with permanent stenting). Peri-operative complications included T-tube (3), primary closure group (9), and trans-cystic (0). There was no statistical significant difference (Chi-square test, P = 0.296) between the groups. There was a trend towards a shorter length of stay in the primary closure group as compared with the trans-cystic and T-tube groups of 4.16, 4.44, and 6.33 days, respectively. However, it did not reach statistical significance (one-way analysis of variance with Boneferroni correction, mean difference between groups 1.89, 0.28, 2,17, statistical significance at P < 0.05). The shortest operating time was in the primary closure group (95.92 min) which was statistically significant (P < 0.001). We did not use a biliary drain in the last 48 patients. CONCLUSIONS: Primary laparoscopic closure of the CBD is safe and results in a reduction in operating time. Choledochoscopy ensures clearance of the CBD and eliminates the need for T-tube.

RESUMO

INTRODUCTION: Gall bladder carcinoma is a rare malignancy that carries a very poor prognosis. Laparoscopic cholecystectomy (LC) is established as the gold-standard treatment for symptomatic gall stones. The aim of the study was to assess the incidence of gall bladder carcinoma and the possibility of reducing the routine histological examination of gall bladder specimens. PATIENTS AND METHODS: Pathology laboratory data of gall bladder specimens over a period of 5 years (June 2000 to July 2005) were analysed retrospectively. The case notes were retrieved in all cases of malignancies. RESULTS: The total number of specimens was 1452. Four (0.27%) cases of primary gall bladder carcinoma, one case of primary B-cell lymphoma and one secondary carcinoma were detected as well as one case of intra-epithelial neoplasia. Operative notes revealed that there was a high index of suspicion of malignancy in all cases. Of the 4 primary gall bladder carcinomas, 3 were stage T2 and one T4. Pre-operative ultrasound suspected carcinoma in only one case but a thickened gall bladder wall was noted in all cases. CONCLUSIONS: All cases of gall bladder carcinoma were suspected pre-operatively or intra-operatively. Histological examination did not alter the management or outcome in any of the cases. We suggest that selectively sending specimens for histopathological examination would result in reduced demands on the histopathology department without compromising patient safety.

RESUMO

Several compelling lines of evidence suggest an important influence of genetic variation in susceptibility to Kawasaki disease (KD), an acute vasculitis that causes coronary artery aneurysms in children. We performed a family-based genotyping study to test for association between KD and 58 genes involved in cardiovascular disease and inflammation. By analysis of a cohort of 209 KD trios using the transmission disequilibrium test, we documented the asymmetric transmission of five alleles including the interleukin-4 (IL-4) C(-589)T allele (P=0.03). Asymmetric transmission of the IL-4 C(-589)T was replicated in a second, independent cohort of 60 trios (P=0.05, combined P=0.002). Haplotypes of alleles in IL-4, colony-stimulating factor 2 (CSF2), IL-13, and transcription factor 7 (TCF7), all located in the interleukin gene cluster on 5q31, were also asymmetrically transmitted. The reported associations of KD with atopic dermatitis and allergy, elevated serum IgE levels, eosinophilia, and increased circulating numbers of monocyte/macrophages expressing the low-affinity IgE receptor (FCepsilonR2) may be related to effects of IL-4. Thus, the largest family-based genotyping study of KD patients to date suggests that genetic variation in the IL-4 gene, or regions linked to IL-4, plays an important role in KD pathogenesis and disease susceptibility.

RESUMO

BACKGROUND: To study the long-term impact on general health status of D-transposition of the great arteries (D-TGA) after the arterial switch operation (ASO) during infancy, we asked parents to complete the Child Health Questionnaire, Parent Form-50 when their children were 8 years old. METHODS AND RESULTS: Of 160 eligible patients, questionnaires were completed for 155 subjects (96%). Median age at surgery was 6 days (range 1 to 67 days), and median age at completion of the Child Health Questionnaire was 8.1 years (7.6 to 10.0 years). Subsequent to questionnaire completion, children underwent psychometric testing. Mean Physical Health Summary and Psychosocial Summary scores were 54.0+/-6.1 and 49.7+/-9.9, respectively, which were similar to those of normal subjects. Compared with the normative sample, parents of D-TGA patients reported more problems with attention, learning, and speech, as well as greater frequency of developmental delay (P<0.001 for each). Worse Psychosocial Summary scores were significantly associated with lower full-scale IQ (P=0.001) and lower achievement in reading (P=0.005) and math (P=0.007). Worse Physical Health Summary scores were associated with longer hospital stay after the ASO (P=0.02). General health status scores were not significantly related to presence of ventricular septal defect, age at surgery, perfusion variables during the ASO, sex, or history of cardiac reoperation. CONCLUSIONS: At age 8 years, children with D-TGA after ASO have an overall physical and psychosocial health status similar to that of the general population. Lower IQ and academic achievement are associated with worse psychosocial health status, whereas longer hospital course after initial surgery is associated with worse physical health status.

RESUMO

BACKGROUND: Transjugular intrahepatic shunts are widely used for the management of variceal bleeding. Complications such as stent misplacement or migration may occur. METHODS: We describe the management of a transjugular intrahepatic shunts stent that migrated across the tricuspid valve in a patient with Child-Pugh category C cirrhosis. RESULTS: An attempt at percutaneous retrieval of the stent was unsuccessful. Due to the unacceptably high risk for mortality from open heart surgery with cardiopulmonary bypass in the setting of cirrhosis, stent removal was deferred until the time of orthotopic liver transplantation. The procedures were performed successfully, and the patient made a good recovery. CONCLUSION: Surgical stent extraction and valve repair can be performed safely along with orthotopic liver transplantation in carefully selected patients with end-stage liver disease.

RESUMO

OBJECTIVE: Methotrexate is currently used as a treatment for refractory inflammatory bowel disease. This study sought to evaluate the hepatic effects of long-term methotrexate therapy in patients with inflammatory bowel disease and to determine whether the established guidelines for monitoring methotrexate-related hepatotoxicity with surveillance liver biopsy in patients with psoriasis or rheumatoid arthritis are applicable to these patients. METHODS: Thirty-two patients with inflammatory bowel disease receiving cumulative methotrexate doses of > or = 1500 mg were studied. Liver chemistry tests were obtained before and during therapy. Twenty patients underwent liver biopsies as recommended for methotrexate-treated patients with psoriasis; the biopsies were reviewed and graded according to Roenigk's criteria for methotrexate-induced hepatotoxicity (a grading system for methotrexate hepatotoxicity in psoriasis patients) by a liver pathologist blinded to the methotrexate dose. RESULTS: In patients who had liver biopsies, the mean cumulative methotrexate dose was 2633 mg (range, 1500-5410 mg), given for a mean of 131.7 wk (range, 66-281 wk). Nineteen of 20 patients (95%) had mild histological abnormalities (Roenigk's grade I and II), and one patient had hepatic fibrosis (Roenigk's grade IIIB). Abnormal liver chemistry tests, present in 6 of 20 (30%) patients, did not identify the patient with Roenigk's grade IIIB hepatotoxicity. CONCLUSIONS: Cumulative methotrexate doses up to 5410 mg given up to 281 wk in patients with inflammatory bowel disease are associated with little hepatotoxicity. Surveillance liver biopsies based on cumulative methotrexate doses are not warranted in these patients.

RESUMO

BACKGROUND: Uridine diphosphate-glucuronosyltransferase-1A1 deficiency, causing Gilbert's syndrome, has been attributed to two extra (TA) bases in the TATAA-box of the promoter region of its gene, where the A(TA)6TAA allele corresponds to the normal gene and A(TA)7TAA corresponds to a gene with reduced expression. Our aim was to determine whether isolated hyperbilirubinemia in liver transplant recipients was due to Gilbert's syndrome acquired through the liver allograft. METHODS: From 305 patients followed in our Liver Transplant Clinic, five patients with isolated unconjugated hyperbilirubinemia in the absence of hemolysis, recurrent viral hepatitis, and biliary tract pathology were identified; 10 other post-orthotopic liver transplantion patients with normal liver chemistry tests were randomly selected as a control group. DNA was extracted from paraffin-embedded liver allograft tissue and peripheral lymphocytes and was genotyped for the TA repeat at the uridine diphosphate glucononosyltransferase-lA1 promoter region by polymerase chain reaction and acrylamide gel electrophoresis. Homozygosity for the (TA)7 allele was considered diagnostic of Gilbert's syndrome. RESULTS: The mean serum total bilirubin level of the study patients was 2.28 mg/dl (range 1.8-3.0), consisting predominantly of the unconjugated form; that of the control patients was 0.76 mg/dl (range 0.4-1.1). The liver tissue from all five patients in the study group possessed the homozygous A(TA)7TAA genotype that was not observed in their lymphocytes. None of the liver tissue from the control patients demonstrated homozygosity for the A(TA)7TAA allele. CONCLUSION: Uridine diphosphate-glucuronosyltransferase-1A1 deficiency, causing Gilbert's syndrome, may be carried by the donor liver and present with isolated unconjugated hyperbilirubinemia in liver transplant recipients.

RESUMO

A 16-year-old man developed heat stroke during football practice when the temperature was 33.8 degrees C (heat index, 44.4 degrees C). Resuscitation with ice water lavage, external cooling, and intravenous fluids was initially successful, but the patient again became obtunded. Liver chemistry tests and the prothrombin time and serum ammonia increased markedly, and rhabdomyolysis and renal failure became evident, necessitating hemodialysis. He underwent liver transplantation for fulminant hepatic failure approximately 72 hours after admission. Rhabdomyolysis with renal failure and severe electrolyte disturbances continued despite aggressive hemodialysis and the patient had a cardiopulmonary arrest and died 10 days after transplantation. This case shows that liver transplantation cannot always overcome the generalized toxic effects of heat stroke. More aggressive hemodialysis or combined liver/kidney transplantation might result in a positive outcome in selected cases.
