AbstractAddiction recovery has gained considerable attention over the past few years. Despite the diffuse conceptualization of ‘recovery’, a range of studies have been conducted on what recovery means. Even though cocaine is the most frequently used stimulant drug, little qualitative research has been done on recovery from cocaine addiction. This study provides more insight into the personal perspectives of (former) cocaine-dependent individuals. In-depth interviews (n?=?23) were conducted in a cocaine-specific treatment programme (CRA?+?vouchers) in Belgium. According to respondents, cocaine addiction recovery is a process that concerns an identity shift, building on personal strengths and utilizing sources of support from the close social network and society. The results showed some specific features regarding the recovery process of individuals in recovery from cocaine addiction, since ‘socially integrated’ cocaine users had a head start due to advantages such as being employed and having a social network. Support should be tailored to the specific needs of individuals in recovery and social networks and communities that support recovery are needed. 相似文献

Preclinical approaches to assess potential kinase inhibitor‐induced cardiac toxicity: Past,present and future 下载免费PDF全文
Over a decade ago, use of tyrosine kinase inhibitors (TKIs) for the treatment of malignancies was found to cause left ventricular dysfunction, a finding that was unexpected and not well predicted by standard preclinical studies. Subsequently, several preclinical approaches were proposed to address this issue. Over the last 5 years, several approaches for preclinical evaluation of cardiac function using isolated perfused hearts, engineered heart tissue and human‐induced pluripotent stem cell‐derived cardiac myocytes have been shown to be relatively predictive of the cardiotoxic potential of TKIs. Further, preclinical studies submitted for regulatory review for recently approved KIs have demonstrated various forms of KI‐induced cardiotoxicity. Thus, early identification and assessment of cardiotoxicity in the preclinical setting is now possible. Given that kinases are involved in diverse cellular processes common to both normal and tumor cells, KI‐induced toxicity, particularly in the heart, appears difficult to avoid. To develop drugs with fewer adverse effects, better efficacy and safety assessments, such as pharmacological separation of targets for cancer from heart, and/or wider separation of the drug concentrations for antitumor activity from cardiac toxicity, may be helpful. Additional preclinical approaches for assessing drug efficacy and toxicity in parallel may include use of animal cancer models and a 3D integrated in vitro model of perfused tumor and heart tissues. Minimizing and predicting potential KI‐induced cardiotoxicity is still an important regulatory challenge, and better preclinical approaches may help achieve this goal. 相似文献

Objective
To assay peripheral inter-ictal cytokine serum levels and possible relations with non-invasive vagus nerve stimulation (nVNS) responsiveness in migraineurs.Methods
This double-blinded, sham-controlled study enrolled 48 subjects and measured headache severity, frequency [headache days/month, number of total and mild/moderate/severe classified attacks/month], functional state [sleep, mood, body weight, migraine-associated disability] and serum levels of inflammatory markers [inter-ictal] using enzyme-linked immunoassays at baseline and after 2 months of adjunctive nVNS compared to sham stimulation and suitably matched controls.Results
No significant differences were observed at baseline and after 2 months for headache severity, total attacks/month, headache days/month and functional outcome [sleep, mood, disability] between verum and sham nVNS. However, the number of severe attacks/month significantly decreased in the verum nVNS group and circulating pro-inflammatory IL-1β was elevated significantly in the sham group compared to nVNS. Levels of anti-inflammatory IL-10 were significantly higher at baseline in both groups compared to healthy controls, but not at 2 months follow-up [p?<?0.05]. Concentrations of high-mobility group box-1 (HMGB-1), IL-6, tumor-necrosis factor-α (TNF-α), leptin, adiponectin, ghrelin remained unchanged [p?>?0.05]. No severe device-/stimulation-related adverse events occurred.Conclusion
2 months of adjunctive cervical nVNS significantly declined the number of severe attacks/month. Pro-inflammatory IL-1β plasma levels [inter-ictal] were higher in sham-treated migraine patients compared to verum nVNS. However, pro- [IL-6, HMGB-1, TNF-α, leptin] and anti-inflammatory [IL-10, adiponectin, ghrelin] mediators did not differ statistically. Profiling of neuroinflammatory circuits in migraine to predict nVNS responsiveness remains an experimental approach, which may be biased by pre-analytic variables warranting large-scale biobank-based systematic investigations [omics]. 相似文献9.
