Recovered memories of childhood sexual abuse: a concise social history of the phenomenon, and the key psychological concepts relevant to understanding the disputes concerning such claims

The alleged and disputed repression of serious, traumatic and repeated childhood sexual abuse memories, and their recovery, usually with psychotherapy and 'memory recovery techniques', have become a major social phenomenon in the last 15 years. This review picks out the key historical, theoretical, research and legal milestones during that period. Key concepts and a review of the inconsistent usage of language and definitions are highlighted to assist the reader to understand the nature of the dispute. A comparison is drawn between this phenomenon and the parallel social history of claims of alien abductions in the US for the purpose of hybrid breeding. A comparison is also made between the boundaries of natural memory functioning as currently understood, and that imputed to questionable recovered memories of childhood sexual assault.     

Therapy of patients with human T-cell lymphotrophic virus I-induced adult T-cell leukemia with anti-Tac, a monoclonal antibody to the receptor for interleukin-2

Human T-cell lymphotropic virus I (HTLV-I)-induced adult T-cell leukemia (ATL) cells constitutively express interleukin-2 (IL-2) receptors identified by the anti-Tac monoclonal antibody (MoAb), whereas normal resting cells do not. This observation provided the scientific basis for a trial of intravenous anti-Tac in the treatment of nine patients with ATL. The patients did not suffer untoward reactions and did not have a reduction in the normal formed elements of the blood, and only one of the nine produced antibodies to the anti-Tac MoAb. Three patients had transient mixed, partial, or complete remissions lasting from 1 to more than 8 months after anti-Tac therapy, as assessed by routine hematologic tests, immunofluorescence analysis of circulating cells, and molecular genetic analysis of HTLV-I provirus integration and of the T-cell receptor gene rearrangement. The precise mechanism of the antitumor effects is unclear; however, the use of a MoAb that prevents the interaction of IL-2 with its receptor on ATL cells provides a rational approach for the treatment of this malignancy.     

Negative emotions and quality of life six months after cardiac surgery: the dominant role of depression not anxiety symptoms

The specific syndromal aspects of depression and anxiety have not been explored in relation to changes in health related quality of life (HRQOL) after cardiac surgery. The purpose of this study was to examine the impact of general stress, depression and anxiety on HRQOL after coronary artery bypass graft (CABG) surgery. Utilizing a tripartite conceptual model of depression and anxiety, it was hypothesized that general stress symptoms, rather than unique depressive or anxiogenic symptoms, would be associated with lower HRQOL 6 months after CABG surgery. Elective CABG patients (n = 226) completed baseline and postoperative self-report measures of negative emotions and HRQOL, and 193 patients completed these measures at 6-month follow-up. Multiple linear regression analyses and logit link analyses were performed to test the hypothesis. Elevated depression symptoms before and after surgery showed an association with lower and worse HRQOL for vitality and social role functioning and physical and general health. This study adds to previous research by outlining discrete associations between specific HRQOL domains, and is perhaps the first to test a theoretical model of depression and anxiety in relation to cardiac CABG patients’ perceptions of HRQOL. These findings encourage further research on negative emotions and HRQOL in cardiac surgery patients and the practical implications of these findings are discussed.     

冠状动脉粥样硬化ADAMTS7新位点的发现和冠状动脉粥样硬化中ABO位点与心肌梗死的相关性:两项全基因组关联研究

<正>背景:该研究旨在评价在现有的冠状动脉粥样硬化的病变中,遗传因素对粥样硬化斑块进展及特异性心肌梗死是否存在显著作用。方法:对欧洲后裔参与者冠状动脉造影表型进行了两项全基因组关联研究(GWAS),为寻找冠状动脉疾病(CAD)易感性基因位点,研究比较了有异常(n=12393)和无异常的(对照组n=7383)个体;为寻找心肌梗死易感性基因位点,也同时比较了造影证实存在CAD并且有心肌梗死的个体(n=5783)与虽有CAD但无心肌梗死的个体(n=3644)。     

Pre-Operative Modification of Dietary Glycemic Index Improves Pre but Not Post-Operative Indices of Insulin Resistance in Patients Undergoing Coronary Artery Bypass Graft Surgery

Background: Improving insulin sensitivity in coronary artery bypass grafting (CABG) patients may translate into improved glycemic control and postoperative outcomes. The implementation of a low glycemic index (LGI) diet in the pre-operative period may improve insulin sensitivity and subsequently impact on the development of post-operative insulin resistance. The aim of this study was to determine whether a short term LGI diet would reduce postoperative insulin resistance.

Methods: Eleven non-diabetic patients referred for elective CABG surgery were randomized to consume either a high glycemic index (HGI)(5) or LGI (6) diet for three weeks prior to their surgery. Outcomes, including insulin sensitivity (SITT, HOMA), were measured at baseline, preoperatively and postoperatively.

Results: Substitution of HGI or LGI foods resulted in an average 8.6 unit increase, or 11.0 unit decrease, respectively, in glycemic index. Insulin sensitivity (HOMA) improved significantly in the LGI group preoperatively compared to the HGI group (p = 0.018). Insulin sensitivity (SITT) was significantly reduced postoperatively in both groups, but no significant difference was found between groups. There was a trend in the LGI group towards improved glycemic control which warrants further investigation.

Conclusion: A preoperative LGI diet presents a non-invasive cardio-protective opportunity warranting clinical trial.
