Canada continues to experience an escalating opioid overdose crisis that has claimed more than 8000 lives in the country since 2016. The presence of the synthetic opioid fentanyl and its analogues is a central contributor to the increases in preventable opioid-related deaths. However, a number of converging social-structural factors (e.g., the continued criminalisation of drug use, political changes) and political barriers are also complicating and contributing to the current crisis. We briefly outline four harm reduction interventions (i.e., injectable opioid agonist treatment, naloxone distribution programs, overdose prevention sites, and drug checking services) as emerging and rapidly expanding responses to this crisis in Canada. These examples of innovation and expansion are encouraging but also occurring at the same time that the opioid overdose crisis shows few signs of abating. To truly address the crisis, Canada needs political environments at all government levels that are responsive and foster harm reduction innovation and drug policy experimentation.  相似文献

ObjectiveConventional deep brain stimulation (DBS) systems with ring-shaped leads generate spherical electrical fields. In contrast, novel directional leads use segmented electrodes. Aim of this study was to quantify the impedance variations over time in subjects with the directional Cartesia-Boston® system.MethodsImpedance records, programming settings, and clinical data of 11 consecutive Parkinsonian patients implanted with DBS directional leads in two Italian centers (Udine and Vicenza) were retrospectively evaluated. Data were collected before starting stimulation (in the operating room and at days 5 and 40) and after switching stimulation on at the successive follow-up visits (1, 6 and 12 months).ResultsDirectional leads have significantly higher impedance than ring leads. Stimulated contacts had always lower impedance compared to non-stimulated contacts. Before DBS-on, all contacts had higher impedance in the operating room, with an initial decrease five days post-surgery and a subsequent increase at day 40, more evident for directional contacts. The impedance of directional leads increased post-implantation at 1 and 6 months with a plateau at 12 months.ConclusionsThere was a significant difference between the directional and ring leads at baseline (before activation of DBS) and during follow-up (chronic DBS).SignificanceOur study reveals new information about the impedance of segmented electrodes that is useful for patient management during the initial test period, as well as during long-term DBS follow-up.  相似文献

Over the past decade, the unfortunate reality is that the income gap has widened between Canadian families. Educational outcomes are one of the key areas influenced by family incomes. Children from low-income families often start school already behind their peers who come from more affluent families, as shown in measures of school readiness. The incidence, depth, duration and timing of poverty all influence a child’s educational attainment, along with community characteristics and social networks. However, both Canadian and international interventions have shown that the effects of poverty can be reduced using sustainable interventions. Paediatricians and family doctors have many opportunities to influence readiness for school and educational success in primary care settings.  相似文献

The effectiveness of educational activities on changing the handwashing habits of preschool children was evaluated using parental surveys and direct observations. Baseline handwashing behaviors were observed and recorded, and parents completed a pre-intervention survey. After interventions were administered, post-intervention data was collected on preschoolers' handwashing habits. Children participated in one, three or five handwashing intervention activities. Results of this study indicate that the educational activities implemented resulted in increased knowledge of the importance of proper handwashing and in positive changes in the children's handwashing habits, particularly for the children who participated in all five interventions.  相似文献

The event of preterm birth represents a significant risk to the equilibrium of the family, often placing the family under significant stress. This paper is intended to assist neonatal nurses in understanding factors related to a family's appraisal of stress and strategies used for coping. Such factors are an important consideration in planning the most effective interventions to support optimal family adaptation to their preterm infant's birth. In identifying the best clinical approaches to supporting a family coping with the event of a preterm birth, nurses need to consider levels of the evidence that supports adoption of clinical intervention strategies. Working to reduce family stress and improve family coping ensures the most optimal home environment for the preterm infant to grow and thrive in after discharge.  相似文献

老年人是营养不良的高发人群,营养不良与众多不良临床结局密切相关,严重影响老年人的身体健康和生活质量,给家庭和社会造成沉重负担。因此,采取有效措施改善老年人的营养不良至关重要,非药物干预是改善营养状况的重要措施。然而,国内尚无专门针对营养不良老年人的非药物干预临床实践指南,因此,中国老年护理联盟、国家老年医学中心和国家老年疾病临床医学研究中心的营养专家,通过对老年人营养不良最新的国内外文献的全面检索与分析,采用推荐意见评估、制订及评价(GRADE)分级体系制订了本指南,针对营养不良老年人非药物干预提出9条推荐意见,以期能够改善老年人营养不良状况,提高生活质量。本指南侧重于可经口进食的营养不良老年人,聚焦于肠内营养,肠外营养不在本指南讨论范围内。  相似文献

Although evidence abounds that people with intellectual disabilities are exposed to stigma and discrimination, few interventions have attempted to tackle stigma among the general public. This study set out to assess the impact of two brief indirect contact interventions on lay people's inclusion attitudes, social distance and positive behavioral intentions, and to explore emotional reactions towards the two interventions. 925 participants completed the first online survey. Participants were randomized to watch either a 10 min film based on intergroup contact theory, or a film based on a protest message. In total, 403 participants completed the follow-up survey at one month. Both interventions were effective at changing inclusion attitudes and social distance in the short term and these effects were partially maintained at one month. The protest based intervention had a greater effect compared to the contact one on aspects of inclusion attitudes and evoked stronger emotional reactions. Despite small effect sizes, brief indirect contact interventions may have a potential role in tackling public stigma associated with intellectual disability but their effects on behavioral intentions are questionable.  相似文献

ObjectivePeople with cancer can experience psychological distress but do not always desire, or engage with, professional support to assist with managing distress. Interventions that are self-directed or guided by patients may hold promise as they allow patients to engage with interventions as they need. The objective of this review is to describe and appraise the evidence for effectiveness of self-guided interventions that aim to manage psychological distress in people with cancer.MethodsA systematic search of Medline, PsychInfo and CINAHL identified 15 relevant papers, reporting on 14 studies.ResultsOf the interventions, three studies comprised hard-copy workbooks, six studies used resource packs, four were online resources and one was a brief multimedia resource. One study was adequately powered and demonstrated a positive effect. Almost all interventions required some level of facilitation. Distressed participants may benefit more from interventions.ConclusionSelf-guided interventions represent a potentially efficient way of delivering support for people affected by cancer, however evidence supporting them is lacking.Practice implicationsThere is a need to generate evidence to understand the impact of self-guided interventions for: i) the ideal delivery point in the disease trajectory, ii) patient groups, iii) intervention content and iv) type and mode of delivery.  相似文献
