Narrowing the focus: Therapeutic cell surface targets for refractory triple-negative breast cancer

Triple-negative breast cancer (TNBC) is defined as a type of breast cancer with lack of expression of estrogen receptor, progesterone receptor and human epidermal growth factor 2 protein. In comparison to other types of breast cancer, TNBC characterizes for its aggressive behavior, more prone to early recurrence and a disease with poor response to molecular target therapy. Although TNBC is identified in only 25%-30% of American breast cancer cases annually, these tumors continue to be a therapeutic challenge for clinicians for several reasons: Tumor heterogeneity, limited and toxic systemic therapy options, and often resistance to current standard therapy, characterized by progressive disease on treatment, residual tumor after cytotoxic chemotherapy, and early recurrence after complete surgical excision. Cell-surface targeted therapies have been successful for breast cancer in general, however there are currently no approved cell-surface targeted therapies specifically indicated for TNBC. Recently, several cell-surface targets have been identified as candidates for treatment of TNBC and associated targeted therapies are in development. The purpose of this work is to review the current clinical challenges posed by TNBC, the therapeutic approaches currently in use, and provide an overview of developing cell surface targeting approaches to improve outcomes for treatment resistant TNBC.     

Training for a new environment: Using military operational concepts in counseling veterans

Since September 11, 2001, the United States has engaged in an extended period of military conflict, resulting in 4.1 million men and women serving in support of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn. Whereas not all servicemembers experience mental health issues, many have experienced difficulties with readjusting to the civilian world, often requiring mental health services both inside and outside of the Department of Veterans Affairs. Issues related to stigma and military culture contribute to barriers not only for veterans seeking treatment but for clinicians providing services who may lack experience with military culture. This article provides a framework to use military concepts in clinical sessions to further therapeutic engagement with the military/veteran client.     

Mental health research priorities in Australia: a consumer and carer agenda

Background

The perspectives of mental health consumers and carers are increasingly recognised as important to the development and conduct of research. However, research directions are still most commonly developed without consumer and carer input. This project aimed to establish priorities for mental health research driven by the views of consumers and carers in Australia.

Method

The project was conducted in two studies. Firstly, a face-to-face discussion forum held in the Australian Capital Territory (Study 1; n?=?25), followed by a national online survey (Study 2; n?=?70). Participants in both studies were members of the community who identified as a mental health consumer, carer or both. In Study 1, participants developed topics for mental health research in small group discussions, then voted on which topics, developed across all groups and sorted into thematic areas, were a priority. An online survey was developed from these research topics. Study 2 participants were asked to rate topics on a 5-point priority scale and rank the relative importance of the highest-rated topics.

Results

At the forum, 79 topics were generated and grouped into 14 thematic areas. Votes on priorities were spread across a large number of topics, with the greatest overall support for research relating to integrating care that is sensitive to past experiences of trauma into mental health service delivery (trauma-informed care). Survey responses were similarly spread, with the majority of research topics rated as important by at least 50% of participants and no clear individual priorities for research identified. Amongst items rated as important by approximately 80% of participants, key research areas included the delivery of services, and consumer and carer involvement.

Conclusions

Australian mental health consumers and carers demonstrate a strong understanding of the mental health system and its inadequacies. Although clear specific priorities are difficult to establish, consistent areas of focus are services and the role consumers and carers can play in their improvement. However, for consumer and carer views to be at the forefront of research, it is important to regularly update research agendas and work in partnership across the whole research process.

     

Preterm low birth weights associated with periodontal disease in the Fiji Islands

AIM: To determine any association between pre-term low birth weight (PTLBW) neonates and periodontal disease during the mother's pregnancy. DESIGN: A multi-centered prospective case cohort study. SETTING: Ante-natal clinics at the Colonial War Memorial and Lautoka Hospitals, Fiji from 1st January to 30th June 2004. PARTICIPANTS: 670 multiethnic pregnant women. METHODS: Participants were interviewed to identify confounding variables--medical conditions, smoking, alcohol consumption, maternal age and history of preterm birth. Oral examination was conducted and included the Community Periodontal Index of Treatment Needs (CPITN). Delivery outcome was recorded for each woman. RESULTS: The mean age of participants was 25.80 +/- 5.56 years. 1.9% (n=13) women delivered preterm babies. More than 50% of this group displayed moderate to severe periodontitis compared with 13% of women who had a normal delivery. Preterm birth was also associated with the mother having had a previous preterm birth and who was more likely to be Indo-Fijian (p < 0.01). There was no significant association with where the mother lived; however, rural women with PTLBW babies had more severe periodontal disease (p = 0.0001). CONCLUSION: There is a highly significant association between pre-term birth and moderate to severe periodontal disease (p = 0.0001).
