Perspective transformation: Women in long-term recovery from alcohol abuse

Objective. The purpose of this study was to determine the meaning of personal transformation for twenty women in long term, stable recovery from alcohol abuse; to identify themes or patterns of this recovery, and; to determine the extent to which they experienced the phenomenon of perspective transformation. ^ Method. Volunteers were recruited by advertisement, word of mouth, and through a closed circuit web based broadcast. A descriptive, exploratory study, which analyzed perspective transformation from the standpoint of five action phases, was conducted. Data was collected using in-depth personal interviews and questionnaires. Subjects' responses were analyzed by qualitative methods. Triangulation was performed on the grouped data comparing the interviews to the data produced by the questionnaires. Quantitative analysis of questionnaire items explored behavioral changes experienced before and after alcoholism recovery. ^ Results. Five phases of recovery were identified. Phase I which involved recognition that alcohol was a problem and change might be possible took several years during which 3 major transitions occurred: (1) from often being alienated to having relationships with family and friends; (2) from daily upheavals to eventually a more peaceful existence, and; (3) from denial that alcohol was a problem to acceptance and willingness to change. Recovery was often seen in a spiritual context, which also required ongoing support. During Phase II there was an assessment of self, others, and the environment which revealed a pattern of intense unhappiness and negative feelings toward self and others with a disregard for cultural norms. Phase III revealed a period of desperation as life became unmanageable, but gradual willingness to accept support and guidance and a desire to improve self and help others. This led to improvement of existing role performance and the willingness to try out new roles. In Phase IV there was a pattern of personal growth which included: the establishment of boundaries, setting priorities, a willingness to place others' needs above their own, acceptance of responsibility, and learning to cope without alcohol, often with the use of tools learned in AA. During Phase V, many experienced knowledge of frailties but growing respect for self and others, with an improved ability to function in giving relationships. Implications for Prevention and Recovery: Early education concerning addiction and recovery may play a crucial role in prevention and early recovery, as it did for children of women in this study. Recovery requires persistent effort and organized support. ^

A focused ethnographic study of women in recovery from alcohol abuse

Alcohol abuse and its related problems are among the most pervasive health and social concerns in the United States (U.S.) today. Women are especially vulnerable to the physical and social devastation of alcohol abuse. Yet, although there is extensive research about alcohol drinking patterns, treatment strategies, and early recovery, there is little information about the factors that facilitate successfully sustained abstinence in women. The purpose of this study was to examine and describe the common factors to successful recovery from alcohol abuse among women and to place these factors within both the context of their social networks and the larger social environment. This study draws from the population of New Mexico, where alcohol-related deaths are the highest of any state in the U.S. and the leading cause of death for individuals under the age of 65 years. The study was a focused ethnography of women who had successfully maintained long-term recovery from alcohol abuse. As an ethnographic study, data collection included participant observation, in-depth interviews with 21 women, and the collection of historical and current culturally relevant data. A purposive sampling plan was used to maximize the selection of participants who had used traditional and non-traditional approaches to recovery. As such, the analysis of the success narratives revealed two distinct findings: the first that women used several different trajectories to achieve long-term recovery. Three trajectory typologies were identified from the success narratives and labeled, A.A. as ceremony, A.A. as grounding, and Recovery as self-management. ^ However, within each of these trajectories, variations in successful recovery were seen. The second major finding was that all women articulated an overarching theme of connections as an indispensable aspect of sustained recovery. The success narratives demonstrated the powerful role that connections played in their long-term recovery and the analysis distinguished two unifying concepts of connections—those that focused beyond self (spirituality, social support, and pets) and those that focused toward self (self-nurturance, agency, and identity). This discussion will focus on the implications for clinical practice related to both women who are still actively abusing alcohol and for those who are successfully maintaining long-term recovery. ^

Astrocytes from the contused spinal cord inhibit oligodendrocyte differentiation of adult oligodendrocyte precursor cells by increasing the expression of bone morphogenetic proteins.

Promotion of remyelination is an important therapeutic strategy to facilitate functional recovery after traumatic spinal cord injury (SCI). Transplantation of neural stem cells (NSCs) or oligodendrocyte precursor cells (OPCs) has been used to enhance remyelination after SCI. However, the microenvironment in the injured spinal cord is inhibitory for oligodendrocyte (OL) differentiation of NSCs or OPCs. Identifying the signaling pathways that inhibit OL differentiation in the injured spinal cord could lead to new therapeutic strategies to enhance remyelination and functional recovery after SCI. In the present study, we show that reactive astrocytes from the injured rat spinal cord or their conditioned media inhibit OL differentiation of adult OPCs with concurrent promotion of astrocyte differentiation. The expression of bone morphogenetic proteins (BMP) is dramatically increased in the reactive astrocytes and their conditioned media. Importantly, blocking BMP activity by BMP receptor antagonist, noggin, reverse the effects of active astrocytes on OPC differentiation by increasing the differentiation of OL from OPCs while decreasing the generation of astrocytes. These data indicate that the upregulated bone morphogenetic proteins in the reactive astrocytes are major factors to inhibit OL differentiation of OPCs and to promote its astrocyte differentiation. These data suggest that manipulation of BMP signaling in the endogenous or grafted NSCs or OPCs may be a useful therapeutic strategy to increase their OL differentiation and remyelination and enhance functional recovery after SCI.

THE ROLE OF E2F1 IN THE RESPONSE TO DNA DOUBLE STRAND BREAKS

The importance of E2F transcription factors in the processes of proliferation and apoptosis are well established. E2F1, but not other E2F family members, is also phosphorylated and stabilized in response to various forms of DNA damage to regulate the expression of cell cycle and pro-apoptotic genes. E2F1 also relocalizes and forms foci at sites of DNA double-strand breaks but the function of E2F1 at sites of damage is still unknown. Here I reveal that E2F1 deficiency leads to increased spontaneous DNA break and impaired recovery following exposure to ionizing radiation. In response to DNA double-strand breaks, NBS1 phosphorylation and foci formation are defective in cells lacking E2F1, but NBS1 expression levels are unaffected. Moreover, it was observed that an association between NBS1 and E2F1 is increased in response to DNA damage, suggesting that E2F1 may promote NBS1 foci formation through a direct or indirect interaction at sites of DNA breaks. E2F1 deficient cells also display impaired foci formation of RPA and Rad51, which suggests a defect in DNA end resection and formation of single-stranded DNA at DNA double-strand breaks. I also found E2F1 status affects foci formation of the histone acetyltransferase GCN5 in response to DNA double-strand breaks. E2F1 is phosphorylated at serine 31 (serine 29 in mouse) by the ATM kinase as part of the DNA damage response. To investigate the importance of this event, our lab developed an E2F1 serine 29 mutant mouse model. I find that E2F1 serine 29 mutant cells show loss of E2F1 foci formation in response to DNA double-strand breaks. Furthermore, DNA repair and NBS1 foci formation are impaired in E2f1S29A/S29A cells. Taken together, my results indicate novel roles for E2F1 in the DNA damage response, which may directly promote DNA repair and genome maintenance.
