Male parental investment is expected to be associated with high confidence of paternity. Studies of species with exclusive male parental care have provided support for this hypothesis because mating typically co-occurs with each oviposition, allowing control over paternity and the allocation of care. However, in systems where males invest by feeding mates (typically arthropods), mating (and thus the investment) is separated from egg-laying, resulting in less control over insemination, as male ejaculates compete with rival sperm stored by females, and a greater risk of investing in unrelated offspring (cuckoldry).

Recognition of the role of biofilms in ∼80% of chronic infections, their contribution to bacterial tolerance and development of antimicrobial resistance, and thus the search for compounds with antibiofilm properties, has increased greatly in recent years. The need for robust experimental methods is therefore critical but currently undermined by inappropriate controls when dimethyl-sulfoxide (DMSO) is used to enhance test compound solubility.

Methods: Thirty-seven children, 2-7 years of age, scheduled for adenoidectomy were enrolled into this prospective study at Rockhampton, Australia. Adenoid biopsy and nasopharyngeal aspirate bacteriology were assessed by conventional culture.
Respiratory diseases place an immense burden on global health and there is a compelling need for the discovery of new compounds for therapeutic development. Here, we identify research priorities by critically reviewing pre-clinical and clinical studies using extracts and compounds derived from molluscs, as well as traditional molluscan medicines, used in the treatment of respiratory diseases. We reviewed 97 biomedical articles demonstrating the anti-inflammatory, antimicrobial, anticancer, and immunomodulatory properties of >320 molluscan extracts/compounds with direct relevance to respiratory disease, in addition to others with promising bioactivities yet to be tested in the respiratory context.

This cross-sectional study assessed whether the Information-Motivation-Behavioural Skills (IMB) Model explained physical activity levels in adults with T2D across different body mass index (BMI) levels (N = 381). Measures included the American Adults Knowledge of Exercise Recommendations (AAKER), Behavioural Regulation in Exercise Questionnaire (BREQ-2), Barriers Specific Self-Efficacy Scale (BARSE) and the outcome measure, International Physical Activity Questionnaire (IPAQ-short form).
View Article and Find Full Text PDFObjective: In a sample of adults with type 2 diabetes mellitus (T2DM), the aim of this study was to examine whether self-reported physical activity level is associated with recall of specific physical activity-related interactions used by general practitioners (GP).
Research Design And Methods: Adults with T2DM completed an online survey reporting physical activity behaviors and recall of 14 GP-patient interactions about physical activity, mapped onto discrete behavior change techniques (BCT). Stepped logistical regression examined associations between recommended physical activity (≥600 MET-min/week) and GP-patient interactions, controlling for body mass index, diabetes-related comorbidities, depressive symptoms and self-efficacy.
Aims: We examined: (a) the prevalence of comorbid elevated symptoms of anxiety/depression; (b) its demographic/clinical correlates; (c) associations with self-care behaviors, by diabetes type.
Methods: Cross-sectional self-report data of 6590 adults with diabetes (42% type 1; 58% type 2) from the Australian and Dutch Diabetes MILES studies were used. Elevated symptoms of anxiety/depression were defined as GAD-7 ≥ 10/PHQ-9 ≥ 10.
Objectives: Regulatory T lymphocytes (T) have been linked to survival of commensal bacteria at mucosal sites, but their presence and role in chronic otitis media (COM) and their response to otopathogens has not been evaluated previously. We investigated the association between T lymphocytes and otopathogens in COM prone and non-COM prone children.
Methods: Forty children, 2-7 years of age, scheduled for adenoidectomy were enrolled into COM (n = 20) or non-COM (n = 20) groups.

Introduction: Optimal glycaemia can reduce type 2 diabetes (T2D) complications. Observing retrospective continuous glucose monitoring (r-CGM) patterns may prompt therapeutic changes but evidence for r-CGM use in T2D is limited. We describe the protocol for a randomised controlled trial (RCT) examining intermittent r-CGM use (up to 14 days every three months) in T2D in general practice (GP).

Retinal screening is key to the early detection of diabetic retinopathy, with risk of vision loss significantly reduced by timely treatment thereafter. Despite this, retinal screening rates are low among this at-risk group.
View Article and Find Full Text PDFAim: Diabetes distress captures a range of emotional responses and reactions to life with diabetes and is considered a part of the experience of managing diabetes and its treatment. Given the importance of the social context of work life for people of working age we set out to explore whether work-related diabetes distress is a distinct and important dimension of diabetes-related emotional distress in working people with type 1 diabetes.
Methods: A questionnaire with self-reported measures of psychosocial health and well-being at work was completed by 1126 working people with type 1 diabetes from a specialist diabetes clinic in Denmark.
Objectives: We aimed to (a) culturally and linguistically adapt the Type 1 Diabetes Stigma Assessment Scale (DSAS-1) from English (for Australia) into Danish and (b) examine psychometric properties of the measure among Danish adults with type 1 diabetes.
Methods: We performed a forward-backward translation, face validity interviews with experts and cognitive debriefing of the Danish version (DSAS-1 DK) with ten adults from the target group. The DSAS-1 DK was then completed by 1594 adults with type 1 diabetes.
Background: While the number of diabetes-specific mobile applications (apps) continues to grow, there is a lack of knowledge about their actual use.
Methods: The second MILES (Management and Impact for Long-term Empowerment and Success)-Australia study was a national cross-sectional survey of the psychological, behavioral, and social aspects of diabetes for adults with type 1 diabetes (T1D) and type 2 diabetes (T2D). Associations between diabetes-specific app usage and demographic, clinical, and psychosocial variables were examined.
Aims: Screening for depression is recommended internationally. The World Health Organization's 5-item Well-being Index (WHO-5) is used clinically to screen for depression but its empirical suitability for this purpose is not well documented. We investigated the psychometric properties of the WHO-5 and its suitability for identifying likely depression in Australian adults with diabetes.

Retinal screening is essential to detect DR, yet screening rates for this group are low and little is known about the underlying factors influencing this important behavior. Using the theoretical domains framework (TDF) to guide data collection and analysis, we explored screening barriers and facilitator, contrasting them with a comparator group of older adults with T2D (40+ years).

Methods: Diabetes MILES-Australia is a national survey of adults with diabetes, focused on behavioral and psychosocial issues. Data from 705 respondents with Type 2 DM were analyzed, including: demographic and clinical characteristics, PA (IPAQ-SF), depressive symptoms (PHQ-9), and BMI (self-reported height and weight).
Background: The use of mobile applications ("apps") for diabetes management is a rapidly developing area and has relevance to adolescents who tend to be early technology adopters. Apps may be useful for supporting self-management or connecting young people with type 1 diabetes (T1D) with their peers. However, outside controlled trials testing the effectiveness of apps, little is known about app usage in this population.

Around one-third of adolescents with type 1 diabetes need mental health support. Parents of a child with type 1 diabetes are also at increased risk of psychological distress.
View Article and Find Full Text PDFObjective: To develop and validate a self-report measure of perceived and experienced stigma for use with adults with type 2 diabetes: the Type 2 Diabetes Stigma Assessment Scale (DSAS-2).
Research Design And Methods: An item pool was drafted based on qualitative data from 25 adults with type 2 diabetes and content from other health-related stigma questionnaires. Thirteen adults with type 2 diabetes completed 57 draft diabetes stigma items and participated in cognitive debriefing interviews.
Background: As type 2 diabetes (T2DM) is a progressive chronic condition, regular clinical review and treatment intensification are critical for prevention of long-term complications. Our aim was to explore the personal impact of insulin therapy, both positive and negative consequences, and attitudes towards future insulin intensification.
Methods: Twenty face-to-face interviews were conducted, and transcripts were analysed using thematic inductive analysis.
While there is evidence that spouses can impact the self-management of adults with type 2 diabetes mellitus, less is known about the influence of the wider social network. This qualitative study explored the perceived impact of the family as well as friends and work colleagues on type 2 diabetes mellitus self-management. A total of 25 adults with type 2 diabetes mellitus participated in semi-structured interviews regarding their social experiences of living with diabetes.

While criterion and convergent validity were good, Rasch analysis revealed suboptimal precision and targeting, and item misfit. Unresolvable multidimensionality within the Diabetes Distress Scale suggests a total score should be avoided, while suboptimal precision suggests that the Physician-related and Interpersonal distress subscales should be used cautiously.
