Micronutrient Supplementation in Children with Autism Spectrum Disorder: An Open-Label Trial

Aim: To investigate the change in core and associated behaviours of autism spectrum disorder (ASD) following micronutrient supplementation. Methods: Adolescents and adults with ASD (N=16, aged 11-22) participated in an 8-week open label study of micronutrients supplements. Measures of behaviour and social responsiveness, using Autism Behaviour Inventory – Short (ABI-S) and Social Responsiveness Scale (SRS) respectively, were completed by parents and teachers at baseline and end of the study. Paired t-tests were used to compare the pre- and post-treatment mean scores. Results: Eleven participants completed the study. Mean scores on both clinical outcomes showed improvements (decreases) over the study period, but none were statistically significant. Parent-reported ABI-S scores decreased (improved) by 11.5% (effect size=-0.52, p=0.08), teacher-reported ABI-S scores improved by 3.7% (effect size=-0.16, p=0.31), and parent-reported SRS scores improved by 8.6% (effect size=-0.56, p=0.05). There were no adverse events reported. Conclusion: This study adds to the mixed findings of micronutrient supplementation in individuals with ASD, consistent with previous studies. Micronutrients were safely tolerated. In the future, randomized controlled trials with a larger sample size are needed to provide more insight on the potential benefits of micronutrients in ASD

Rethinking Sustainability to Meet the Climate Change Challenge

A group of environmental law professors formed the Environmental Law Collaborative with the goal of engaging environmental law scholars in the thorny issues of the day. The members of the Collaborative gathered in the summer of 2012 to produce an intensive and collective assessment of sustainability in the age of climate change. Their writings examine the process of adapting the principles and application of sustainability to the demands of climate change, including framing the term sustainability in climate change discussions; coordinating sustainable practices across disciplines such as law, economics, ethics, and the hard sciences; and conceptualizing the role of sustainability in formulating adaptation and resiliency strategies. Their work also contemplates the role of law and legal systems in crafting effective climate change adaptation strategies and considers feasible strategies in the context of specific examples

Construction and evaluation of novel rhesus monkey adenovirus vaccine vectors

Adenovirus vectors are widely used as vaccine candidates for a variety of pathogens, including HIV-1. To date, human and chimpanzee adenoviruses have been explored in detail as vaccine vectors. The phylogeny of human and chimpanzee adenoviruses is overlapping, and preexisting humoral and cellular immunity to both are exhibited in human populations worldwide. More distantly related adenoviruses may therefore offer advantages as vaccine vectors. Here we describe the primary isolation and vectorization of three novel adenoviruses from rhesus monkeys. The seroprevalence of these novel rhesus monkey adenovirus vectors was extremely low in sub-Saharan Africa human populations, and these vectors proved to have immunogenicity comparable to that of human and chimpanzee adenovirus vaccine vectors in mice. These rhesus monkey adenoviruses phylogenetically clustered with the poorly described adenovirus species G and robustly stimulated innate immune responses. These novel adenoviruses represent a new class of candidate vaccine vectors. IMPORTANCE Although there have been substantial efforts in the development of vaccine vectors from human and chimpanzee adenoviruses, far less is known about rhesus monkey adenoviruses. In this report, we describe the isolation and vectorization of three novel rhesus monkey adenoviruses. These vectors exhibit virologic and immunologic characteristics that make them attractive as potential candidate vaccine vectors for both HIV-1 and other pathogens

Seasonality of MRSA Infections

Using MRSA isolates submitted to our hospital microbiology laboratory January 2001–March 2010 and the number of our emergency department (ED) visits, quarterly community-associated (CA) and hospital-associated (HA) MRSA infections were modeled using Poisson regressions. For pediatric patients, approximately 1.85x (95% CI 1.45x–2.36x, adj. p<0.0001) as many CA-MRSA infections per ED visit occurred in the second two quarters as occurred in the first two quarters. For adult patients, 1.14x (95% CI 1.01x–1.29x, adj.p = 0.03) as many infections per ED visit occurred in the second two quarters as in the first two quarters. Approximately 2.94x (95% CI 1.39x–6.21x, adj.p = 0.015) as many HA-MRSA infections per hospital admission occurred in the second two quarters as occurred in the first two quarters for pediatric patients. No seasonal variation was observed among adult HA-MRSA infections per hospital admission. We demonstrated seasonality of MRSA infections and provide a summary table of similar observations in other studies

Rapid Seeding of the Viral Reservoir Prior to SIV Viremia in Rhesus Monkeys

The viral reservoir represents a critical challenge facing HIV-1 eradication strategies1–5. However, it remains unclear when and where the viral reservoir is seeded during acute infection and the extent to which it is susceptible to early antiretroviral therapy (ART). Here we show that the viral reservoir is seeded very early following mucosal SIV infection of rhesus monkeys and prior to systemic viremia. We initiated suppressive ART in groups of monkeys on days 3, 7, 10, and 14 following intrarectal SIVmac251 infection. Treatment on day 3 blocked the emergence of viral RNA and proviral DNA in peripheral blood and also substantially reduced levels of proviral DNA in lymph nodes and gastrointestinal mucosa as compared with treatment at later timepoints. In addition, treatment on day 3 abrogated the induction of SIV-specific humoral and cellular immune responses. Nevertheless, following discontinuation of ART after 24 weeks of fully suppressive therapy, virus rebounded in all animals, although animals treated on day 3 exhibited a delayed viral rebound as compared with animals treated on days 7, 10 and 14. The time to viral rebound correlated with total viremia during acute infection and with proviral DNA at the time of ART discontinuation. These data demonstrate that the viral reservoir is seeded very early following intrarectal SIV infection of rhesus monkeys, during the “eclipse” phase, and prior to viremia. This strikingly early seeding of the refractory viral reservoir raises important new challenges for HIV-1 eradication strategies

Solar Feasibility Study at Wesley United Methodist Church

This project evaluated the feasibility of installing a photovoltaic system on the roof of the Wesley United Methodist Church in Worcester, MA. Analysis of the site, weather data, and economic incentives available to church facilitated the creation of a model that could predict the value of a photovoltaic system as an economic investment. This analysis resulted in a long payback period, but projections using this model indicate significant changes as the price of photovoltaic panels continue to fall
