The role of micro-organisms (staphylococcus aureus and Candida Albicans) in the pathogenesis of breast pain and infection in lactation women : study protocol

Background: The CASTLE (Candida and Staphylococcus Transmission: Longitudinal Evaluation) study will investigate the micro-organisms involved in the development of mastitis and “breast thrush” among breastfeeding women. To date, the organism(s) associated with the development of breast thrush have not been identified. The CASTLE study will also investigate the impact of physical health problems and breastfeeding problems on maternal psychological health in the early postpartum period.

Methods/Design: The CASTLE study is a longitudinal descriptive study designed to investigate the role of Staphylococcus spp (species) and Candida spp in breast pain and infection among lactating women, and to describe the transmission dynamics of S. aureus and Candida spp between mother and infant. The relationship between breastfeeding and postpartum health problems as well as maternal psychological well-being is also being investigated. A prospective cohort of four hundred nulliparous women who are at least thirty six weeks gestation pregnant are being recruited from two hospitals in Melbourne, Australia (November 2009 to June 2011). At recruitment, nasal, nipple (both breasts) and vaginal swabs are taken and participants complete a questionnaire asking about previous known staphylococcal and candidal infections. Following the birth, participants are followed-up six times: in hospital and then at home weekly until four weeks postpartum. Participants complete a questionnaire at each time points to collect information about breastfeeding problems and postpartum health problems. Nasal and nipple swabs and breast milk samples are collected from the mother. Oral and nasal swabs are collected from the baby. A telephone interview is conducted at eight weeks postpartum to collect information about postpartum health problems and breastfeeding problems, such as mastitis and nipple and breast pain.

Discussion: This study is the first longitudinal study of the role of both staphylococcal and candidal colonisation in breast infections and will help to resolve the current controversy about which is the primary organism in the condition known as breast thrush. This study will also document transmission dynamics of S. aureus and Candida spp between mother and infant. In addition, CASTLE will investigate the impact of common maternal physical health symptoms and the effect of breastfeeding problems on maternal psychological well-being.

An evaluation of a national program to implement the cornell scale for depression in dementia into routine practice in aged care facilities

Background: Screening tools have been recommended for use in aged care to improve the detection and treatment of depression. This study aimed to evaluate the impact of a program for the routine implementation of the Cornell Scale for Depression in Dementia in Australian facilities, to determine whether use of the instrument by nurses led to further monitoring of depressive symptoms, medical referral, and changes in treatments prescribed for depression.
Methods: A file review was completed for 412 participants out of a total of 867 older people (47.5%) who resided in ten aged care facilities. The review examined Cornell Scale assessment data, medication charts, medical history, nursing progress notes, and resident care plans. Nursing staff who administered the Cornell Scale to each participant were also interviewed, and ten facilitymanagers took part in an interview to determine barriers to the effective implementation of the instrument.
Results: The Cornell Scale had been administered to 46.8% of the sample in the previous 12 months, with 25% of these participants scoring 9–13 and 27% scoring 14 and above. Less than one third of the residents with high scores were monitored by the staff following the assessment. Only 18% of residents with high scores were referred for further assessment of depression, while 10% received a treatment change.
Conclusions: The absence of a protocol for responding to high Cornell Scale scores limited the potential of this program to result in widespread improved treatment of depressed older people. The use of the Cornell Scale by aged care nurses with limited training raised concern.

"The solution needs to be complex." Obese adults' attitudes about the effectiveness of individual and population based interventions for obesity

Background
Previous studies of public perceptions of obesity interventions have been quantitative and based on general population surveys. This study aims to explore the opinions and attitudes of obese individuals towards population and individual interventions for obesity in Australia.

Methods
Qualitative methods using in-depth semi-structured telephone interviews with a community sample of obese adults (Body Mass Index ≥30). Theoretical, purposive and strategic recruitment techniques were used to ensure a broad sample of obese individuals with different types of experiences with their obesity. Participants were asked about their attitudes towards three population based interventions (regulation, media campaigns, and public health initiatives) and three individual interventions (tailored fitness programs, commercial dieting, and gastric banding surgery), and the effectiveness of these interventions.

Results
One hundred and forty two individuals (19-75 years) were interviewed. Participants strongly supported non-commercial interventions that were focused on encouraging individuals to make healthy lifestyle changes (regulation, physical activity programs, and public health initiatives). There was less support for interventions perceived to be invasive or high risk (gastric band surgery), stigmatising (media campaigns), or commercially motivated and promoting weight loss techniques (commercial diets and gastric banding surgery).

Conclusion
Obese adults support non-commercial, non-stigmatising interventions which are designed to improve lifestyles, rather than promote weight loss.

'Just bloody fat!' : a qualitative study of body image, self esteem and coping in obese adults

The rise of the ‘obesity epidemic’ in Western societies has led to an increased public gaze on obese individuals. Yet there is limited research that explores through qualitative methods the increased impact it has had on obese individuals’ perceptions of self, body image and coping strategies, using their own words. This paper presents the findings of interviews with a community sample of 142 obese adults in Australia. We examined how obese individuals felt about themselves and their bodies, what influenced these feelings, and the subsequent coping strategies employed. While participants were able to identify many positive characteristics about their inner self, the vast majority used negative language to describe their physical appearance. Many participants described feelings of ‘guilt’, ‘shame’ and ‘blame’ associated with their weight. Coping strategies included striving for perfection in other areas of their life, social isolation, maximising aspects of their appearance and ‘fat’ acceptance. This study shows that, while different groups of obese adults experience, cope with and compensate for the influence of weight-based stereotyping in many different ways, they still feel an unrelenting otherness and difference associated with their weight.

Do health beliefs and behaviors differ according to severity of obesity? A qualitative study of Australian adults

Public responses to obesity have focused on providing standardized messages and supports to all obese individuals, but there is limited understanding of the impact of these messages on obese adults. This descriptive qualitative study using in-depth interviews and a thematic method of analysis, compares the health beliefs and behaviors of 141 Australian adults with mild to moderate (BMI 30−39.9) and severe (BMI ≥ 40) obesity. Mildly obese individuals felt little need to change their health behaviors or to lose weight for health reasons. Most believed they could “lose weight” if they needed to, distanced themselves from the word obesity, and stigmatized those “fatter” than themselves. Severely obese individuals felt an urgent need to change their health behaviors, but felt powerless to do so. They blamed themselves for their weight, used stereotypical language to describe their health behaviors, and described being “at war” with their bodies. Further research, particularly about the role of stigma and stereotyping, is needed to fully understand the impact of obesity messaging on the health beliefs, behaviors, and wellbeing of obese and severely obese adults.

"I don't eat a hamburger and large chips every day!" A qualitative study of the impact of public health messages about obesity on obese adults

Background
We are a society that is fixated on the health consequences of 'being fat'. Public health agencies play an important role in 'alerting' people about the risks that obesity poses both to individuals and to the broader society. Quantitative studies suggest people comprehend the physical health risks involved but underestimate their own risk because they do not recognise that they are obese.

Methods
This qualitative study seeks to expand on existing research by exploring obese individuals' perceptions of public health messages about risk, how they apply these messages to themselves and how their personal and social contexts and experiences may influence these perceptions. The study uses in depth interviews with a community sample of 142 obese individuals. A constant comparative method was employed to analyse the data.

Results
Personal and contextual factors influenced the ways in which individuals interpreted and applied public health messages, including their own health and wellbeing and perceptions of stigma. Individuals felt that messages were overly focused on the physical rather than emotional health consequences of obesity. Many described feeling stigmatised and blamed by the simplicity of messages and the lack of realistic solutions. Participants described the need for messages that convey the risks associated with obesity while minimising possible stigmatisation of obese individuals. This included ensuring that messages recognise the complexity of obesity and focus on encouraging healthy behaviours for individuals of all sizes.

Conclusion
This study is the first step in exploring the ways in which we understand how public health messages about obesity resonate with obese individuals in Australia. However, much more research - both qualitative and quantitative - is needed to enhance understanding of the impact of obesity messages on individuals.

Development of an online intervention for bipolar disorder. www.moodswings.net.au

We describe the development process and completed structure, of a self-help online intervention for bipolar disorder, known as MoodSwings (www.moodswings.net.au). The MoodSwings program was adapted as an Internet intervention from an efficacious and validated face-to-face, group-based psychosocial intervention. The adaptation was created by a psychologist, who had previously been involved with the validation of the face-to-face program, in collaboration with website designers. The project was conducted under the supervision of a team of clinician researchers. The website is available at no cost to registered participants. Self-help modules are accessed sequentially. Other features include a mood diary and a moderated discussion board. There has been an average of 1,475,135 hits on the site annually (2008 and 2009), with some 7400 unique visitors each year. A randomised controlled trial based on this program has been completed. Many people with bipolar disorder are accepting of the Internet as a source of treatment and, once engaged, show acceptable retention rates. The Internet appears to be a viable means of delivering psychosocial self-help strategies.

A qualitative investigation of obese men's experiences with their weight

Objectives: To investigate obese men's health behaviors and strategies for change. Methods: Qualitative interviews with 36 men (BMI 30 and over). Results: All men felt personally responsible for their weight gain. Sedentary lifestyles, stress, lack of worklife balance and weight-based stigma were all significant causes of weight gain and barriers to weight loss. These factors also contributed to men's unwillingness to seek help for their overweight. Conclusion: Addressing the self-blame and stigma associated with obesity is important in developing strategies to improve the health and well-being of obese men.

A randomised, controlled trial of a dietary intervention for adults with major depression (the "SMILES" trial): study protocol

Despite increased investment in its recognition and treatment, depression remains a substantial health and economic burden worldwide. Current treatment strategies generally focus on biological and psychological pathways, largely neglecting the role of lifestyle. There is emerging evidence to suggest that diet and nutrition play an important role in the risk, and the genesis, of depression. However, there are limited data regarding the therapeutic impact of dietary changes on existing mental illness. Using a randomised controlled trial design, we aim to investigate the efficacy and cost-efficacy of a dietary program for the treatment of Major Depressive Episodes.

Optimizing prediction of binge eating episodes : a comparison approach to test alternative conceptualizations of the affect regulation model

Background : Although a wealth of studies have tested the link between negative mood states and likelihood of a subsequent binge eating episode, the assumption that this relationship follows a typical linear dose–response pattern (i.e., that risk of a binge episode increases in proportion to level of negative mood) has not been challenged. The present study demonstrates the applicability of an alternative, non-linear conceptualization of this relationship, in which the strength of association between negative mood and probability of a binge episode increases above a threshold value for the mood variable relative to the slope below this threshold value (threshold dose response model).

Methods : A sample of 93 women aged 18 to 40 completed an online survey at random intervals seven times per day for a period of one week. Participants self-reported their current mood state and whether they had recently engaged in an eating episode symptomatic of a binge.

Results : As hypothesized, the threshold approach was a better predictor than the linear dose–response modeling of likelihood of a binge episode. The superiority of the threshold approach was found even at low levels of negative mood (3 out of 10, with higher scores reflecting more  negative mood). Additionally, severity of negative mood beyond this threshold value appears to be useful for predicting time to onset of a binge episode.

Conclusions : Present findings suggest that simple dose–response formulations for the association between  negative mood and onset of binge episodes miss vital aspects of this relationship. Most  notably, the impact of mood on binge eating appears to depend on whether a threshold value  of negative mood has been breached, and elevation in mood beyond this point may be useful  for clinicians and researchers to identify time to onset.

A randomized head to head trial of MoodSwings.net.au: an internet based self-help program for bipolar disorder.

Adjunctive psychosocial interventions are efficacious in bipolar disorder, but their incorporation into routine management plans are often confounded by cost and access constraints. We report here a comparative evaluation of two online programs hosted on a single website (www.moodswings.net.au). A basic version, called MoodSwings (MS), contains psychoeducation material and asynchronous discussion boards; and a more interactive program, MoodSwings Plus (MS-Plus), combined the basic psychoeducation material and discussion boards with elements of Cognitive Behavioral Therapy. These programs were evaluated in a head-to-head study design.
