A critical review of South African child and youth resilience studies, 2009-2017

Abstract: In contexts of high levels of structural disadvantage, such as South Africa, resilience among children and youth becomes increasingly important to buffer children and youth from the negative effects of adversity. This article reports on a systematic review of research conducted in South Africa over the period 2009 to 2017 on the resilience of children and youth (ages 0 to 24) from the perspectives of young people themselves. It serves as a follow-up and refinement of an earlier publication in 2010. A total of 61 journal articles are reviewed. Four categories of social-ecological resilience-enablers emerge from these study, viz. personal, relational, structural and spiritual/cultural. Most of the resilience-enablers identified in these studies are in the personal and relational domains. Various reasons for this finding are discussed, and emerging recommendations for service professionals (particularly social worker and educational psychologists) and youth resilience researchers are advanced

Outcome measures in post-stroke arm rehabilitation trials: do existing measures capture outcomes that are important to stroke survivors, carers, and clinicians?

Objective: We sought to (1) identify the outcome measures currently used across stroke arm rehabilitation randomized trials, (2) identify and compare outcomes important to stroke survivors, carers and clinicians and (3) describe where existing research outcome measures capture outcomes that matter the most to stroke survivors, carers and clinicians and where there may be discrepancies. Methods: First, we systematically identified and extracted data on outcome measures used in trials within a Cochrane overview of arm rehabilitation interventions. Second, we conducted 16 focus groups with stroke survivors, carers and clinicians using nominal group technique, supplemented with eight semi-structured interviews, to identify these stakeholders’ most important outcomes following post-stroke arm impairment. Finally, we described the constructs of each outcome measure and indicated where stakeholders’ important outcomes were captured by each measure. Results: We extracted 144 outcome measures from 243 post-stroke arm rehabilitation trials. The Fugl-Meyer Assessment Upper Extremity section (used in 79/243 trials; 33%), Action Research Arm Test (56/243; 23%), and modified Ashworth Scale (53/243; 22%) were most frequently used. Stroke survivors (n = 43), carers (n = 10) and clinicians (n = 58) identified 66 unique, important outcomes related to arm impairment following stroke. Between one and three outcomes considered important by the stakeholders were captured by the three most commonly used assessments in research. Conclusion: Post-stroke arm rehabilitation research would benefit from a reduction in the number of outcome measures currently used, and better alignment between what is measured and what is important to stroke survivors, carers and clinicians

Volatilização de amônia proveniente de ureia com zeólita natural.

O objetivo deste trabalho foi avaliar os efeitos da adição de zeólita a grânulos de ureia e dos diâmetros de grânulos nas perdas de NH3 por volatilização e na absorção de N pelo sorgo. Formulações de ureia com adição de zeólita e ligante orgânico, nos diâmetros menores que 2 mm, 2?4 mm e maiores que 4 mm e, sulfato de amônio e ureia‑NBPT, foram aplicados à superfície do solo sobre bandejas, em casa de vegetação. A adição de zeólitas naturais à superfície dos grânulos de ureia ou à composição destes diminuiu as perdas por volatilização em 20% e aumentou a extração de N pelas plantas. A acumulação de N nas plantas de sorgo foi inversamente proporcional às perdas de N por volatilização

Esculetin provides neuroprotection against mutant huntingtin-induced toxicity in huntington’s disease models

Huntington’s disease (HD) is a neurodegenerative disorder caused by an abnormal CAG trinucleotide repeat expansion within exon 1 of the huntingtin (HTT) gene. This mutation leads to the production of mutant HTT (mHTT) protein which triggers neuronal death through several mechanisms. Here, we investigated the neuroprotective effects of esculetin (ESC), a bioactive phenolic compound, in an inducible PC12 model and a transgenic Drosophila melanogaster model of HD, both of which express mHTT fragments. ESC partially inhibited the progression of mHTT aggregation and reduced neuronal death through its ability to counteract the oxidative stress and mitochondria impairment elicited by mHTT in the PC12 model. The ability of ESC to counteract neuronal death was also confirmed in the transgenic Drosophila model. Although ESC did not modify the lifespan of the transgenic Drosophila, it still seemed to have a positive impact on the HD phenotype of this model. Based on our findings, ESC may be further studied as a potential neuroprotective agent in a rodent transgenic model of HD

Nationwide consensus on quality indicators to assess glaucoma care: A modified Delphi approach

Purpose Performance assessments are essential to tracking and improving quality in health care systems. Key aspects of the care process that act as indicators must be measured in order to gain an in-depth understanding of a care unit's operation. Without standardized quality indicators (QIs), it is difficult to characterize and compare the abilities of institutions to achieve excellence. The aim of this study is to reach a consensus among glaucoma specialists concerning the development of a set of QIs to assess the performance of glaucoma care units. Methods A two-round Delphi technique was performed among glaucoma specialists in Portugal, using a 7-point Likert scale. Fifty-three initial statements (comprising process, structure, and outcome indicators) were evaluated and participants had to agree on which ones would be part of the final set of QIs. Results By the end of both rounds, 28 glaucoma specialists reached consensus on 30/53 (57%) statements, including 19 (63%) process indicators (mainly relating to the proper implementation of complementary exams and the setting of follow-up intervals), 6 (20%) structure indicators, and 5 (17%) outcome indicators. Of the indicators that were part of the final list, functional and structural aspects of glaucoma progression and the availability of surgical/laser procedures were the most prevalent. Conclusions A set of 30 QIs for measuring the performance of glaucoma units was developed using a consensus methodology involving experts in the field. Their use as measurement standards would provide important information about unit operations and allow further implementation of quality improvements

Disease activity states, reasons for discontinuation and adverse events in 1038 Italian children with juvenile idiopathic arthritis treated with etanercept

The advent of biologic medications has increased considerably the potential for treatment benefit in juvenile idiopathic arthritis (JIA), with clinical remission being now achievable in a substantial proportion of patients. However, there is a need of data from the real world of clinical practice to evaluate thoroughly the efficacy and safety profile of the biologic agents currently approved
