RESUMO

Environmental monitoring, particularly of water, is crucial to screen and preselect potential hazardous substances for policy guidance and risk minimisation strategies. In Portugal, extensive data are missing. This work aimed to perform a qualitative survey of antibiotics in surface- groundwater, reflecting demographic, spatial, consumption and drug profiles during an observational period of three years. A passive sampling technique (POCIS) and high-resolution chromatographic system were used to monitor and analyse the antibiotics. The most frequently detected antibiotics were enrofloxacin/ciprofloxacin and tetracycline in surface-groundwater, while clarithromycin/erythromycin and sulfamethoxazole were identified only in surface water. The detection of enzyme inhibitors (e.g., tazobactam/cilastatin) used exclusively in hospitals and abacavir, a specific human medicine was also noteworthy. North (Guimarães, Santo Tirso and Porto) and South (Faro, Olhão and Portimão) Portugal were the regions with the most significant frequency of substances in surface water. The relatively higher detection downstream of the effluent discharge points compared with a low detection upstream could be attributed to a low efficiency in urban wastewater treatment plants and an increased agricultural pressure. This screening approach is essential to identify substances in order to perform future quantitative risk assessment and establishing water quality standards. The greatest challenge of this survey data is to promote an ecopharmacovigilance framework, implement measures to avoid misuse/overuse of antibiotics and slow down emission and antibiotic resistance.

RESUMO

The glutamatergic neurotransmitter system may play an important role in attention-deficit hyperactivity disorder (ADHD). This 5-week, open-label, single-blind, placebo-controlled study reports the safety, pharmacokinetics and responsiveness of the metabotropic glutamate receptor (mGluR) activator fasoracetam (NFC-1), in 30 adolescents, age 12-17 years with ADHD, harboring mutations in mGluR network genes. Mutation status was double-blinded. A single-dose pharmacokinetic profiling from 50-800 mg was followed by a single-blind placebo at week 1 and subsequent symptom-driven dose advancement up to 400 mg BID for 4 weeks. NFC-1 treatment resulted in significant improvement. Mean Clinical Global Impressions-Improvement (CGI-I) and Severity (CGI-S) scores were, respectively, 3.79 at baseline vs. 2.33 at week 5 (P < 0.001) and 4.83 at baseline vs. 3.86 at week 5 (P < 0.001). Parental Vanderbilt scores showed significant improvement for subjects with mGluR Tier 1 variants (P < 0.035). There were no differences in the incidence of adverse events between placebo week and weeks on active drug. The trial is registered at https://clinicaltrials.gov/ct2/show/study/NCT02286817 .

RESUMO

OBJECTIVE: The objective of this project was to develop a community-academic coalition partnership to conduct community-based participatory research (CBPR) to address health disparities in older adults with chronic conditions living in the Quebrada Arriba community. METHODS: We used the 'Developing and Sustaining CPPR Partnerships: A Skill-Building Curriculum', to create the Quebrada Arriba Community-Academic Partnership (QACAP). We assessed the meetings effectiveness and the CBPR experiences of the coalition members in the community-academic partnership. RESULTS: The stepwise process resulted in: the development of The Coalition for the Health and Wellbeing of Older People of Quebrada Arriba; the partnership's mission and vision; the operating procedures; the formulation of the research question, and; the action plan for obtaining funding resources. The mean levels of satisfaction for each of the items of the Meeting Effectiveness Evaluation tool were 100%. The mean agreement rating scores on variables related to having a positive experience with the coalition, members' representativeness of community interest, respectful contacts between members, the coalition's vision and mission, the participation of the members in establishing the prioritized community problem, and sharing of resources between the members was 100%. CONCLUSION: The steps used to build the QACAP provided an effective structure to create the coalition and captured the results of coalition activities. Partners' time to build trust and developing a sufficient understanding of local issues, high interest of the community members, flexibility of the partners, capitalization on the partners' strengths, and the shared decision building process were key contributors of this coalition's success.
