Mindfulness-based interventions for young offenders: a scoping review

Youth offending is a problem worldwide. Young people in the criminal justice system have frequently experienced adverse childhood circumstances, mental health problems, difficulties regulating emotions and poor quality of life. Mindfulness-based interventions can help people manage problems resulting from these experiences, but their usefulness for youth offending populations is not clear. This review evaluated existing evidence for mindfulness-based interventions among such populations. To be included, each study used an intervention with at least one of the three core components of mindfulness-based stress reduction (breath awareness, body awareness, mindful movement) that was delivered to young people in prison or community rehabilitation programs. No restrictions were placed on methods used. Thirteen studies were included: three randomized controlled trials, one controlled trial, three pre-post study designs, three mixed-methods approaches and three qualitative studies. Pooled numbers (n = 842) comprised 99% males aged between 14 and 23. Interventions varied so it was not possible to identify an optimal approach in terms of content, dose or intensity. Studies found some improvement in various measures of mental health, self-regulation, problematic behaviour, substance use, quality of life and criminal propensity. In those studies measuring mindfulness, changes did not reach statistical significance. Qualitative studies reported participants feeling less stressed, better able to concentrate, manage emotions and behaviour, improved social skills and that the interventions were acceptable. Generally low study quality limits the generalizability of these findings. Greater clarity on intervention components and robust mixed-methods evaluation would improve clarity of reporting and better guide future youth offending prevention programs

Matrix metalloproteinases 2 and 9 (gelatinases A and B) expression in malignant mesothelioma and benign pleura

Matrix metalloproteinases (MMPs), in particular the gelatinases (MMP-2 and -9), play a significant role in tumour invasion and angiogenesis. The expression and activities of MMPs have not been characterised in malignant mesothelioma (MM) tumour samples. In a prospective study, gelatinase activity was evaluated in homogenised supernatants of snap frozen MM (n = 35), inflamed pleura (IP, n = 12) and uninflammed pleura (UP, n = 14) tissue specimens by semiquantitative gelatin zymography. Matrix metalloproteinases were correlated with clinicopathological factors and with survival using Kaplan-Meier and Cox proportional hazard models. In MM, pro- and active MMP-2 levels were significantly greater than for MMP-9 (P = 0.006, P<0.001). Active MMP-2 was significantly greater in MM than in UP (P=0.04). MMP-2 activity was equivalent between IP and MM, but both pro- and active MMP-9 activities were greater in IP (P=0.02, P=0.009). While there were trends towards poor survival with increasing total and pro-MMP-2 activity (P=0.08) in univariate analysis, they were both independent poor prognostic factors in multivariate analysis in conjunction with weight loss (pro-MMP-2 P = 0.03, total MMP-2 P = 0.04). Total and pro-MMP-2 also contributed to the Cancer and Leukemia Group B prognostic groups. MMP-9 activities were not prognostic. Matrix metalloproteinases, and in particular MMP-2, the most abundant gelatinase, may play an important role in MM tumour growth and metastasis. Agents that reduce MMP synthesis and/or activity may have a role to play in the management of MM. © 2003 Cancer Research UK

Silence as an element of care:A meta-ethnographic review of professional caregivers’ experience in clinical and pastoral settings

Background: In interactions between professional caregivers, patients and family members at the end of life, silence often becomes more prevalent. Silence is acknowledged as integral to interpersonal communication and compassionate care but is also noted as a complex and ambiguous phenomenon. This review seeks interdisciplinary experience to deepen understanding of qualities of silence as an element of care. Aim: To search for published papers which describe professional caregivers’ experience of silence as an element of care, in palliative and other clinical, spiritual and pastoral care settings and to synthesise their findings. Design: Meta-ethnography: employing a systematic search strategy and line-of-argument synthesis. Data sources: PsycINFO and seven other cross-disciplinary databases, supplemented by hand-search, review of reference lists and citation tracking. No date range was imposed. Inclusion criteria focused on reported experience of silence in professional caregiving. Selected papers (n = 18) were appraised; none were rejected on grounds of quality. Results: International, interdisciplinary research and opinion endorses the value of silence in clinical care. As a multi-functional element of interpersonal relationships, silence operates in partnership with speech to support therapeutic communication. As a caregiving practice, silence is perceived as particularly relevant in spiritual and existential dimensions of care when words may fail. Conclusion: Experience of silence as an element of care was found in palliative and spiritual care, psychotherapy and counselling supporting existing recognition of the value of silence as a skill and practice. Because silence can present challenges for caregivers, greater understanding may offer benefits for clinical practice

Comparison between experimentally determined total, saturated and trans fat levels and levels reported on the labels of cookies and bread sold in Brazil

In Brazil, the National Health Surveillance Agency (ANVISA) made the labeling of trans fats in foods mandatory from July 2006. The claim “trans fat free” can be used only for foods with trans fat content lower than 0.2g and saturated fat content lower than 2g per serving. This study determined fatty acid profile by gas chromatography and total fat content of nine cookie types and three bread types and the results obtained were compared with the values reported on the labels of these products. According to the results, 92% of the products contained trans fat, although only 33% reported this on their labels. There was no significant difference with the experimentally determined levels of the products that reported the presence of trans fat. In 67% of the products that reported an absence of trans fat on their labels, less than 0.2g of trans fat per serving was experimentally detected. The results revealed that the food product manufacturers studied are labeling trans fat content properly according to the law as they report products that have less than 0.2g trans fat as “trans fat free”. However, it bears noting that claiming that a product is free of trans fat on the label does not always guarantee that it is not present in the product and that the maximum suggested daily intake of 2g will not be exceeded relatively easily considering that consumers do not always consume only the amount identified as the serving size on the label. Also, the paper enabled a discussion about the lack of standardization in the description of fat used as ingredient in foods.Vanessa Martins Hissanaga-Himelstein, Mateus Santaella Vivaz Oliveira, Bruna Maria Silveira, David Alejandro González-Chica, Rossana Pacheco da Costa Proença, Jane Mara Bloc
