Il ruolo della religione nelle scelte in ambito biomedico

La salute delle persone può essere influenzata dalla cultura di appartenenza. In particolare le credenze religiose sono coinvolte nella comprensione ed elaborazione delle pratiche biomediche e delle relative scelte pubbliche e private perché determinano la formazione di un personale punto di vista. Un reale consenso tra punti di vista diversi può nascere solo nel caso in cui si mettano a fuoco i propositi, i fondamenti ed i metodi di una bioetica incentrata sul principio di tolleranza.People’s health can be influenced by the culture of belonging. In particular, beliefs are involved in the care and elaboration of biomedical practices and related public and private choices because they determine the formation of a personal point of view. So, a real consensus between different points of view can only arise if the intentions, the foundations and the methods of a bioethics focused on the principle of tolerance are brought into focus

The Suffolk County Sheriff\u27s Department: Correctional Education Program

This article describes the Sheriff\u27s Department correctional education programs at the Suffolk County House of Correction and Jail. It points out the tremendous need for educational services given that more than 60 percent of those incarcerated in these institutions are high school drop-outs, and a much higher percentage are functionally illiterate. Because 95 percent of those incarcerated at this facility will return to their communities within three years, educating prisoners serves as a constructive and cost-effective means of preventing recidivism and an effective investment in public safety. The authors also discusses the new Mandatory Literacy Law, which essentially links literacy with parole and other institutional privileges. Finally, the article suggests that the success of these tightly controlled and highly structured programs may provide important lessons for those charged with repairing the broken down Boston public school system

Parallelization of a Monte Carlo Ray Tracing Algorithm for Channel Modelling in Underwater Wireless Optical Communications

AbstractIn this paper, an algorithm to calculate the underwater wireless optical impulse response is presented. It is based on a modified Monte Carlo Ray Tracing algorithm and takes into account the most significant phenomena of the underwater channel. In order to reduce the simulation time, two parallelization schemes are proposed, one based on a multiprocessor architecture and other based on the use of GPU (Graphics Processing Unit). Several simulation results are presented, including scenario channel simulations and calculation of time computation complexity for each algorithm implementation

Votes at 16: democracy experts respond to Ed Miliband’s proposal

Ed Miliband used his speech to the Labour Party conference this week to announce his support for lowering the voting age to 16 for all UK elections. This follows the decision to allow 16- and 17-year-olds to vote in the Scottish independence referendum. In this post, Democratic Audit asks leading experts and practitioners to respond to Miliband’s proposal

Indoor air pollution and respiratory diseases: A general update and a Portuguese perspective

Objective: To quantify the impact of different air pollutants on respiratory health based on robust estimates based on international data and to summarise the evidence of associations between indoor exposure to those pollutants and respiratory morbidity in the Portuguese population. Results: Several systematic reviews and meta-analyses (MA) at the world level demonstrate the impact of indoor air quality on respiratory health, with indoor particulate matter and gasses exerting a significant effect on the airways. Volatile organic compounds (VOC) have been related to asthma and lung cancer. However, only meta-analyses on biomass use allowed documentation of long-term respiratory effects. While early publications concerning Portuguese-based populations mainly focused on indoor exposure to environmental tobacco smoke, later studies relocated the attention to relevant exposure environments, such as day care buildings, schools, residences and nursing homes. Looking at the pooled effects from the reviewed studies, high levels of carbon dioxide and particulate matter in Portuguese buildings were significantly associated with asthma and wheezing, with VOC and fungi showing a similar effect in some instances. Conclusions: Despite the significant reduction of indoor air pollution effects after the 2008 indoor smoking prohibition in public buildings, studies show that several indoor air parameters are still significantly associated with respiratory health in Portugal. The country shares the worldwide necessity of standardisation of methods and contextual data to increase the reach of epidemiological studies on household air pollution, allowing a weighted evaluation of interventions and policies focused on reducing the associated respiratory morbidity.proofepub_ahead_of_prin

Development and validation of exhaled breath condensate microRNAs to identify and endotype asthma in children

Detection and quantification of microRNAs (miRNAs) in exhaled breath condensate (EBC) has been poorly explored. Therefore we aimed to assess miRNAs in EBC as potential biomarkers to diagnose and endotype asthma in school aged children. In a cross sectional, nested case control study, all the asthmatic children (n = 71) and a random sample of controls (n = 115), aged 7 to 12 years, attending 71 classrooms from 20 local schools were selected and arbitrarily allocated to the development or validation set. Participants underwent skin-prick testing, spirometry with bronchodilation, had exhaled level of nitric oxide determined and EBC collected. Based on previous studies eleven miRNAs were chosen and analyzed in EBC by reverse transcription-quantitative real-time PCR. Principal component analysis was applied to identify miRNAs profiles and associations were estimated using regression models. In the development set (n = 89) two clusters of miRNAs were identified. After adjustments, cluster 1 and three of its clustered miRNAs, miR-126-3p, miR-133a-3p and miR-145-5p were positively associated with asthma. Moreover miR-21-5p was negatively associated with symptomatic asthma and positively associated with positive bronchodilation without symptoms. An association was also found between miR-126-3p, cluster 2 and one of its clustered miRNA, miR-146-5p, with higher FEF25-75 reversibility. These findings were confirmed in the validation set (n = 97) where two identical clusters of miRNAs were identified. Additional significant associations were observed between miR-155-5p with symptomatic asthma, negative bronchodilation with symptoms and positive bronchodilation without symptoms. We showed that microRNAs can be measured in EBC of children and may be used as potential biomarkers of asthma, assisting asthma endotype establishment.Authors gratefully acknowledge the funding by Fundação para a Ciência e Tecnologia through the Project NORTE-01-0145-FEDER-000010 - Health, Comfort and Energy in the Built Environment (HEBE), cofinanced by Programa Operacional Regional do Norte (NORTE2020), through Fundo Europeu de Desenvolvimento Regional (FEDER) and EXALAR 21 project financed by FEDER/FNR and by Fundação para a Ciência e Tecnologia (EXALAR 21 02/SAICT/2017 - Project nº 30193).

Embodiment and social distancing: Practices

A collection of five video essays on embodiment and social distancing, with a focus on practices. RAFFAELE RUFO, “Dancing Together Alone: What Can Be Learnt About Connection When Touch is Forbidden?” (00:10): This video essay reengages the experience of leading a dance improvisation practice on Zoom during the Coronavirus lockdown. As a tango and contact improvisation dancer confined at home, I felt urged to ask: what can be learnt about embodied connection when we are not allowed to physically touch each other? ANAT BEN-DAVID AND CATHARINE ANNE CARY, “What’s the Matter?” (05:54): Performers, scenographers, musicians and wordsmiths Anat Ben-David and Catharine Cary improvised via ZOOM every Tuesday from March to May 2020. Embracing latency, zoom’s affordances, limitations and distortions, they show here excerpts of a transformed body of work. Separated by 5218 km, given the Covid-19 situation, it could have been 200 meters. DEANNA BORLAND-SENTINELLA, LOUISE GWENNETH PHILLIPS, AND ALICE OWEN, “Virtually Embodied: Remembering the Sensations of Connection” (12:04): This film is an exploration of the body: Being present to place and time; being aware of connection with others, whether that be in reality or through virtual connection and sensorial memory. NATHALIE S. FARI, “Notes from a zoom 5Rhythms® session” (17:10): By using a three-hour 5Rhythms® online workshop as basis, this video sheds light into the ways in which the practitioner interacts and engages with both one’s own bodily awareness and the new technology of zoom. AMBERBECKYCREATIVE, “Sheltering in Spacetimematterings: Audiovisual Considerations of Social Distancing” (22:42): Two socially distant authors glitch audiovisual intra-actions through embodied (dis)orientations of space, time, and matter in past/present/future collapsed to (re)present what it’s like to shelter in place during the COVID-19 pandemic

Assessment and determinants of airborne bacterial and fungal concentrations in different indoor environments: Homes, child day-care centres, primary schools and elderly care centres

Until now the influence of risk factors resulting from exposure to biological agents in indoor air has been far less studied than outdoor pollution; therefore the uncertainty of health risks, and how to effectively prevent these, remains. This study aimed (i) to quantify airborne cultivable bacterial and fungal concentrations in four different types of indoor environment as well as to identify the recovered fungi; (ii) to assess the impact of outdoor bacterial and fungal concentrations on indoor air; (iii) to investigate the influence of carbon dioxide (CO2), temperature and relative humidity on bacterial and fungal concentrations; and (iv) to estimate bacterial and fungal dose rate for children (3–5 years old and 8–10 years old) in comparison with the elderly. Air samples were collected in 68 homes, 9 child day-care centres, 20 primary schools and 22 elderly care centres, in a total of 264 rooms with a microbiological air sampler and using tryptic soy agar and malt extract agar culture media for bacteria and fungi growth, respectively. For each building, one outdoor representative location were identified and simultaneously studied. The results showed that child day-care centres were the indoor microenvironment with the highest median bacterial and fungal concentrations (3870 CFU/m3 and 415 CFU/m3, respectively), whereas the lowest median concentrations were observed in elderly care centres (222 CFU/m3 and 180 CFU/m3, respectively). Indoor bacterial concentrations were significantly higher than outdoor concentrations (p < 0.05); whereas the indoor/outdoor ratios for the obtained fungal concentrations were approximately around the unit. Indoor CO2 levels were associated with the bacterial concentration, probably due to occupancy and insufficient ventilation. Penicillium and Cladosporium were the most frequently occurring fungi. Children's had two times higher dose rate to biological pollutants when compared to adult individuals. Thus, due to children's susceptibility, special attention should be given to educational settings in order to guarantee their healthy future development

Effect of antihypertensive treatments on insulin signalling in lympho-monocytes of essential hypertensive patients: a pilot study.

It was previously demonstrated that metabolic syndrome in humans is associated with an impairment of insulin signalling in circulating mononuclear cells. At least in animal models of hypertension, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARB) may correct alterations of insulin signalling in the skeletal muscle. In the first study, we investigated the effects of a 3-month treatment with an ARB with additional PPARγ agonist activity, telmisartan, or with a dihydropyridine calcium channel blocker, nifedipine, on insulin signalling in patients with mild-moderate essential hypertension. Insulin signalling was evaluated in mononuclear cells by isolating them through Ficoll-Paque density gradient centrifugation and protein analysis by Western Blot. An increased expression of mTOR and of phosphorylated (active) mTOR (p-mTOR) was observed in patients treated with telmisartan, but not in those treated with nifedipine, while both treatments increased the cellular expression of glucose transporter type 4 (GLUT-4). We also investigated the effects of antihypertensive treatment with two drug combinations on insulin signalling and oxidative stress. Twenty essential hypertensive patients were included in the study and treated for 4 weeks with lercanidipine. Then they were treated for 6 months with lercanidipine + enalapril or lercanidipine + hydrochlorothiazide. An increased expression of insulin receptor, GLUT-4 and an increased activation of p70S6K1 were observed during treatment with lercanidipine + enalapril but not with lercanidipine + hydrochlorothiazide. In conclusion, telmisartan and nifedipine are both effective in improving insulin signalling in human hypertension; however, telmisartan seems to have broader effects. The combination treatment lercanidipine + enalapril seems to be more effective than lercanidipine + hydrochlorothiazide in activating insulin signalling in human lympho-monocytes
