How can the law in England and Wales be reformed in order to regulate offensive online communications with respect to the right of freedom of expression?

The evolution of social media in recent years has significantly changed the way society interacts and engages with each other. Research has shown that there has been a 21% increase in social media usage by UK adults from 2011 to 2017. This drastic shift regarding the way we communicate can be said to bring many benefits; however, it can also impose serious legal issues. Such legal issues include ‘revenge porn’, online blackmail and ‘trolling’. For the purpose of this investigation, the main focus of the research will be on the area of offensive online communications.The investigation will cover the effectiveness of the current criminal law in terms of offensive online communications. In addition to this, the research will be highlighting any gaps within the current law in regard to overcoming this problem. When considering potential reforms, the right to freedom of expression will remain at the forefront of the research to prevent any alienation of human rights

Identification and antibiotic control of endophytic bacteria contaminants in micropropagated potato explants

Este trabalho teve por objetivos isolar, caracterizar e identificar bactérias endofíticas contaminantes encontradas em tecidos de batata durante a micropropagação e selecionar antibióticos para o controle in vitro desses microrganismos por meio da determinação da concentração bactericida mínima inibitória. Brotações de batata apresentando contaminação bacteriana durante a etapa de multiplicação in vitro, foram superficialmente esterilizadas e os internódios transferidos para placas de Petri com ágar nutriente, onde permaneceram incubadas a 28°C por até cinco dias. Após purificação, as bactérias foram caracterizadas e identificadas por testes taxonômicos. Um total de oito estirpes bacterianas foram isoladas e identificadas como pertencentes às famílias Acetobacteriaceae (1) e Enterobacteriaceae (2) e aos gêneros Corynebacterium (3), Pseudomonas (1) e Xanthomonas (1). Os melhores resultados para a inibição do crescimento bacteriano foram obtidos com os antibióticos ampicilina, cloranfenicol, estreptomicina e tetraciclina em concentrações que variaram de 32 a 256 mg L-1.This work aimed to isolate, characterize and identify contaminant endophytic bacteria found in potato tissues during the micropropagation and to select antibiotics for in vitro control of these microorganisms by determining the inhibitory minimal bactericidal concentration. Potato shoots presenting bacterial contamination during the in vitro multiplication were superficially sterilized and the internodes transferred to Petri dishes with nutrient agar medium for up to five days at 28°C. After subcultures the grown bacteria were purified and identified through taxonomic tests. A total of eight bacterial endophytic strains were isolated and identified as belonging to Acetobacteriaceae (1) and Enterobacteriaceae (2) families and Corynebacterium (3), Pseudomonas (1) and Xanthomonas (1) genera. The best results for bacterial growth inhibition were obtained with ampicilin, chloramphenicol, streptomycin and tetracycline antibiotics in concentrations ranging from 32 to 256 mg L-1

Suicidal ideation in adolescence: Examining the role of recent adverse experiences

Although there is a well-known link between adverse experiences and suicidal ideation, there has been little study of the effects of recent adverse experiences on suicidal ideation in teenagers. This study examined the association between recent adverse experiences and suicidal ideation in a sample of 740 at-risk 16-year-old youth in the LONGSCAN studies, as well as potential mediators. 8.9% of the youth reported suicidal ideation. Recent adverse experiences, as a class, were associated with suicidal ideation; both recent physical abuse and recent psychological maltreatment were uniquely associated with suicidal ideation. The links between recent adverse experiences and suicidal ideation were significantly mediated by psychological distress. There were also significant main effect associations between both internalizing behavioral problems and low positive achievement expectations and suicidal ideation. Recent adverse experiences are important in understanding suicidal ideation in high risk youth

A randomized controlled trial of pretransplant antiviral therapy to prevent recurrence of hepatitis C after liver transplantation

Hepatitis C virus (HCV) infection recurs in liver recipients who are viremic at transplantation. We conducted a randomized, controlled trial to test the efficacy and safety of pretransplant pegylated interferon alpha‐2b plus ribavirin (Peg‐IFN‐α2b/RBV) for prevention of post‐transplant HCV recurrence. Enrollees had HCV and were listed for liver transplantation, with either potential living donors or Model for End‐Stage Liver Disease upgrade for hepatocellular carcinoma. Patients with HCV genotypes (G) 1/4/6 (n = 44/2/1) were randomized 2:1 to treatment (n = 31) or untreated control (n = 16); HCV G2/3 (n=32) were assigned to treatment. Overall, 59 were treated and 20 were not. Peg‐IFN‐α2b, starting at 0.75 μg/kg/week, and RBV, starting at 600 mg/day, were escalated as tolerated. Patients assigned to treatment versus control had similar baseline characteristics. Combined virologic response (CVR) included pretransplant sustained virologic response and post‐transplant virologic response (pTVR), defined as undetectable HCV RNA 12 weeks after end of treatment or transplant, respectively. In intent‐to‐treat analyses, 12 (19%) assigned to treatment and 1 (6%) assigned to control achieved CVR ( P = 0.29); per‐protocol values were 13 (22%) and 0 (0%) ( P = 0.03). Among treated G1/4/6 patients, 23 of 30 received transplant, of whom 22% had pTVR; among treated G2/3 patients 21 of 29 received transplant, of whom 29% had pTVR. pTVR was 0%, 18%, and 50% in patients treated for 16 weeks, respectively ( P = 0.01). Serious adverse events (SAEs) occurred with similar frequency in treated versus untreated patients (68% versus 55%; P = 0.30), but the number of SAEs per patient was higher in the treated group (2.7 versus 1.3; P = 0.003). Conclusion : Pretransplant treatment with Peg‐IFN‐α2b/RBV prevents post‐transplant recurrence of HCV in selected patients. Efficacy is higher with >16 weeks of treatment, but treatment is associated with increased risk of potentially serious complications.

Adverse experiences and suicidal ideation in adolescence: Exploring the link using the LONGSCAN samples.

Although widely studied in adults, the link between lifetime adversities and suicidal ideation in youth is poorly understood. The purpose of this study was to explore this link in adolescents

Liver transplant and hepatitis C in methadone maintenance therapy: a case report

Methadone maintenance therapy for the treatment of opioid dependence continues to carry a social stigma. Until recently, patients on methadone were not considered for liver transplantation. We describe the first case of a patient on methadone who received a liver transplant for end stage liver disease and was successfully treated for recurrent hepatitis C. More than five years post transplant and three years post viral clearance, the patient continues to do well and is stable on low-dose methadone. This case emphasizes the need to reconsider the non-evidence based policy adopted by transplant centers that require methadone maintenance therapy patients to stop methadone prior to consideration for transplant evaluation

Cross-translational studies in human and Drosophila identify markers of sleep loss

Inadequate sleep has become endemic, which imposes a substantial burden for public health and safety. At present, there are no objective tests to determine if an individual has gone without sleep for an extended period of time. Here we describe a novel approach that takes advantage of the evolutionary conservation of sleep to identify markers of sleep loss. To begin, we demonstrate that IL-6 is increased in rats following chronic total sleep deprivation and in humans following 30 h of waking. Discovery experiments were then conducted on saliva taken from sleep-deprived human subjects to identify candidate markers. Given the relationship between sleep and immunity, we used Human Inflammation Low Density Arrays to screen saliva for novel markers of sleep deprivation. Integrin αM (ITGAM) and Anaxin A3 (AnxA3) were significantly elevated following 30 h of sleep loss. To confirm these results, we used QPCR to evaluate ITGAM and AnxA3 in independent samples collected after 24 h of waking; both transcripts were increased. The behavior of these markers was then evaluated further using the power of Drosophila genetics as a cost-effective means to determine whether the marker is associated with vulnerability to sleep loss or other confounding factors (e.g., stress). Transcript profiling in flies indicated that the Drosophila homologues of ITGAM were not predictive of sleep loss. Thus, we examined transcript levels of additional members of the integrin family in flies. Only transcript levels of scab, the Drosophila homologue of Integrin α5 (ITGA5), were associated with vulnerability to extended waking. Since ITGA5 was not included on the Low Density Array, we returned to human samples and found that ITGA5 transcript levels were increased following sleep deprivation. These cross-translational data indicate that fly and human discovery experiments are mutually reinforcing and can be used interchangeably to identify candidate biomarkers of sleep loss

Outcomes in hepatitis C virus–infected recipients of living donor vs. deceased donor liver transplantation

In this retrospective study of hepatitis C virus (HCV)–infected transplant recipients in the 9-center Adult to Adult Living Donor Liver Transplantation Cohort Study, graft and patient survival and the development of advanced fibrosis were compared among 181 living donor liver transplant (LDLT) recipients and 94 deceased donor liver transplant (DDLT) recipients. Overall 3-year graft and patient survival were 68% and 74% in LDLT, and 80% and 82% in DDLT, respectively. Graft survival, but not patient survival, was significantly lower for LDLT compared to DDLT ( P = 0.04 and P = 0.20, respectively). Further analyses demonstrated lower graft and patient survival among the first 20 LDLT cases at each center (LDLT 20; P = 0.002 and P = 0.002, respectively) and DDLT recipients ( P 20 and DDLT were not significantly different ( P = 0.66 and P = 0.74, respectively). Overall, 3-year graft survival for DDLT, LDLT >20, and LDLT 20 were not significantly different. Important predictors of graft loss in HCV-infected patients were limited LDLT experience, pretransplant HCC, and higher MELD at transplantation.

ADESÃO AO TRATAMENTO FISIOTERAPÊUTICO EM ADOLESCENTES COM FIBROSE CÍSTICA

Objetivo: Avaliar o grau de adesão ao tratamento fisioterapêutico em adolescentes com Fibrose Cística (FC) acompanhados em um programa multidisciplinar. Método: Estudo observacional de corte transversal com 14 pacientes do ambulatório multidisciplinar de FC no período de maio de 2016 a outubro de 2016. Foi aplicado um questionário próprio para determinar a adesão da fisioterapia; conjuntamente com a adesão do medicamento alfadornase, analisada através do Teste de Morisky-Green e a gravidade da doença, foi avaliada pela aplicação do Escore de Shwachman-Kulczycki. Resultados: A idade média dos pacientes foi de 15 anos, sendo 8 (57,1%) do sexo masculino. De acordo com o grau de adesão, 5 (35,7%) foram classificados com baixa adesão, 4 (28,6%) com moderada adesão e 5 (35,7%) com alta adesão. O escore de Shwachman-Kulczycki foi classificado em excelente 6 (48,8%), bom 4 (28,5%), leve 3 (21,4%), moderado 1 (7,1%). No presente estudo não foi observada correlação da adesão da fisioterapia com o escore de gravidade, e também com o uso da medicação alfadornase. Conclusão: Foi observada adesão satisfatória (moderada a alta) para fisioterapia respiratória em 64,3% dos adolescentes com FC investigados. No entanto, notou-se um equilíbrio entre baixa adesão e alta adesão (35,7%) para esse tratamento
