RESUMO

BACKGROUND AND AIMS: Type 2 diabetes (T2DM) is a major cause of morbidity and mortality globally. Carnosine, a naturally occurring dipeptide, has anti-inflammatory, antioxidant, and anti-glycating effects, with preliminary evidence suggesting it may improve important chronic disease risk factors in adults with cardiometabolic conditions. METHODS AND RESULTS: In this randomised controlled trial, 43 adults (30%F) living with prediabetes or T2DM consumed carnosine (2 g) or a matching placebo daily for 14 weeks to evaluate its effect on glucose metabolism assessed via a 2-h 75 g oral glucose tolerance test. Secondary outcomes included body composition analysis by dual energy x-ray absorptiometry (DEXA), calf muscle density by pQCT, and anthropometry. Carnosine supplementation decreased blood glucose at 90 min (-1.31 mmol/L; p = 0.02) and 120 min (-1.60 mmol/L, p = 0.02) and total glucose area under the curve (-3.30 mmol/L; p = 0.04) following an oral glucose tolerance test. There were no additional changes in secondary outcomes. The carnosine group results remained significant before and after adjustment for age, sex, and change in weight (all>0.05), and in further sensitivity analyses accounting for missing data. There were no significant changes in insulin levels. CONCLUSION: This study provides preliminary support for larger trials evaluating carnosine as a potential treatment for prediabetes and the initial stages of T2DM. Likely mechanisms may include changes to hepatic glucose output explaining the observed reduction in blood glucose without changes in insulin secretion following carnosine supplementation.

RESUMO

BACKGROUND: Congestive heart failure (CHF) management has proven devastating on morbidity, mortality, quality of life and also costly to health systems. Therapeutics for CHF have advanced and benefited greatly due to large multicentre randomised controlled trials and the evidence obtained from them. Management for chronic diseases and nonpharmaceutical therapies such as chronic disease self-management has lagged, and for CHF the evidence base has even been questioned. METHODS: Perspective and non systematic mini review. CONCLUSIONS: Advancing translational research standards is important to achieve optimal cost effectiveness. Importantly is understanding evidence generation in medicine, identifying the primary roots for management and its translation.

RESUMO

BACKGROUND: Developing strategies to change health behaviour is one of the biggest challenges of health promotion programs. Social media, as a popular and innovative communication and education tool, offers opportunities to modify health behaviour. While literature on using social media for health promotion campaigns is growing, there is a need to evaluate the approaches used to change health behaviour, rather than only creating awareness. OBJECTIVE: The paper reviewed the literature on application of social media in health promotion campaigns with a particular focus on the methodologies used in assessing the outcome of the programs for behaviour change. This fills the void in collating evidence to extend health promotion campaigns to effect sustainable behavioural change. METHOD: Peer-reviewed articles were identified through multiple science databases. A systematic electronic search was conducted to retrieve review and original papers published between January 2010 and April 2022. The titles and abstracts of the articles were screened according to inclusion and exclusion criteria. All authors independently read the full texts and discussed them to reach a consensus about the themes. Concept mapping was used to present results from analysis of the included papers. RESULTS: Of the 674 citations, 28 (4.1%) studies were included in this review. The methodology approaches of 18 (2.7%) papers, that aimed to evaluate the impact of social media in health promotion campaigns towards behaviour change, were analysed further using concept mapping. The results showed that 10 studies (55.5%) adopted quantitative methods and five studies (27.7%) used mixed methods and three studies (16.6%) used qualitative methods. Facebook and YouTube were used more for intervention purposes to change health behaviour. Twitter and Instagram were used more to observe the trend of changes in health behaviour. Six studies (33.3%) adopted Social Cognitive Theory and one study (5.5%) applied the Transtheoretical Model as the framework to evaluate the outcome. Overall, the results show that though social media has potential in promoting behaviour change, the estimation of this change in long-term lies outside the scope of social media health campaigns. This is also reflected in the methodologies used in existing studies to assess such sustainable changes. The employed measures usually target immediate behaviour or social media engagement rather than addressing the change on a behavioural level. CONCLUSION: Evaluating the performance of social media campaigns to promote health behaviours towards a sustainable outcome is a complex process. Emerging research is focused on evaluating the potential of social media as an opportunity to create awareness. Such measures require less effort in quantifying and isolating the effect. The design of the campaigns is required to be aligned in relation to stages of the behaviour change. The study provides suggestions on how this can be achieved.

RESUMO

Heart Failure (HF), a common chronic disease, requires multidisciplinary care to optimise outcomes. The COVID-19 pandemic, its impact on people's movement and access to health services, introduced severe challenges to chronic disease management. The era that will evolve after this pandemic is likely to provide uncertainty and service model disruptions. HF treatment is based on guidelines derived from randomised clinical trial evidence. Translational shortfalls from trials into practice have been overcome with post-trial service improvement studies like OPTIMIZE-HF where a team using a process of care can translate evidence to the general population. However, gaps remain for vulnerable populations e.g. those with more severe HF, with multiple comorbid conditions, and certain demographic groups and/or residents in remote locations. Health technology has come with great promise, to fill some of these gaps. The COVID-19 pandemic provides an opportunity to observe, from Australian healthcare lens, HF management outside the traditional model of care. This narrative review describes relatively recent events with health technology as a solution to improve on service gaps.

RESUMO

BACKGROUND: Hypertension control remains a major challenge globally. A recent systematic review suggested that yoga has beneficial effects on reducing blood pressure. However, the role of yoga in hypertension management in primary health care has received little attention, and no studies have evaluated the impact of a yoga program fully delivered by health care staff on hypertension. This study, therefore, assessed the effects of a health worker-led yoga intervention on blood pressure reduction among hypertensives patients in the primary care setting. METHODS: This was a multicentric, two-arm, randomised trial conducted among hypertensive patients in seven Ayurveda Health Centres in Nepal between March 2017 and June 2018. One hundred and twenty-one participants who were on or without medications were randomised to intervention (n = 61) and wait-list control (n = 60) groups using stratified block randomisation. Participants in the intervention arm received an intervention consisting of an initial five-day structured yoga training at the centres and then a further home-based practice of yoga for five days a week for the following 90 days. Both intervention and control groups also participated in a 2-h health education session. The primary outcome of this trial was systolic blood pressure at 90-day follow-up. Data were analysed on an intention-to-treat basis using linear mixed-effects regression models. RESULTS: We included all 121 study participants (intervention/control = 61/60) in the primary analysis (52.1% males; mean ± SD age = 47.8 ± 10.8 years). The difference in systolic blood pressure between the intervention group and the control group was - 7.66 mmHg (95% CI: - 10.4, - 4.93). For diastolic blood pressure, the difference was - 3.86 mmHg (95% CI: - 6.65, - 1.06). No adverse events were reported by the participants. CONCLUSIONS: A yoga program for hypertensive patients consisting of a five-day training in health centres and 90 days of practice at home is effective for reducing blood pressure. Significant benefits for hypertensive patients could be expected if such programmes would become a part of the standard treatment practice. TRIAL REGISTRATION: This trial was prospectively registered with the Clinical Trial Registry of India [ CTRI/2017/02/007822 ] on 10/02/2017.

RESUMO

To develop and pilot a tool that assesses the infrastructure and policy workplace environment characteristics that may influence employee healthy eating and physical activity behaviours. A checklist was developed with reference to prior tools and piloted at eight worksites. Piloting of the tool demonstrated that it was generally feasible to use, took 1-2 hours to complete and appeared sensitive to differences between workplace environment characteristics. Refinement of the tool occurred after piloting. The final 21-item checklist contains sub-scores capturing policy, infrastructure, healthy eating and physical activity characteristics. This new checklist overcomes some limitations of pre-existing tools as it explicitly considers policy and is short, inexpensive and can be used by workplaces for self-assessment and by health promotion professionals in evaluation studies or as an intervention tool.

RESUMO

PURPOSE: Vitamin D regulates adipokine production in vitro; however, clinical trials have been inconclusive. We conducted secondary analyses of a randomized controlled trial to examine whether vitamin D supplementation improves adipokine concentrations in overweight/obese and vitamin D-deficient adults. METHODS: Sixty-five individuals with a BMI ≥ 25 kg/m2 and 25-hydroxyvitamin D (25(OH)D) ≤ 50 nmol/L were randomized to oral cholecalciferol (100,000 IU single bolus followed by 4,000 IU daily) or matching placebo for 16 weeks. We measured BMI, waist-to-hip ratio, % body fat (dual X-ray absorptiometry), serum 25(OH)D (chemiluminescent immunoassay) and total adiponectin, leptin, resistin, and adipsin concentrations (multiplex assay; flow cytometry). Sun exposure, physical activity, and diet were assessed using questionnaires. RESULTS: Fifty-four participants completed the study (35M/19F; mean age = 31.9 ± 8.5 years; BMI = 30.9 ± 4.4 kg/m2). After 16 weeks, vitamin D supplementation increased 25(OH)D concentrations compared with placebo (57.0 ± 21.3 versus 1.9 ± 15.1 nmol/L, p < 0.001). There were no differences between groups for changes in adiponectin, leptin, resistin, or adipsin in unadjusted analyses (all p > 0.05). After adjustment for baseline values, season, sun exposure, and dietary vitamin D intake, there was a greater increase in adiponectin (ß[95%CI] = 13.7[2.0, 25.5], p = 0.02) and leptin (ß[95%CI] = 22.3[3.8, 40.9], p = 0.02) in the vitamin D group compared with placebo. Results remained significant after additional adjustment for age, sex, and % body fat (p < 0.02). CONCLUSIONS: Vitamin D may increase adiponectin and leptin concentrations in overweight/obese and vitamin D-deficient adults. Further studies are needed to clarify the molecular interactions between vitamin D and adipokines and the clinical implications of these interactions in the context of obesity. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov: NCT02112721.

RESUMO

Abnormalities of iron homeostasis have been linked to insulin resistance, type 2 diabetes and cardiovascular disease. Carnosine, an over-the-counter food supplement with chelating properties, has been shown to decrease serum iron and improve glucose metabolism in diabetic rodents. We have previously demonstrated that carnosine supplementation prevented worsening of glucose metabolism in healthy overweight and obese middle-aged adults. Yet, the impact of carnosine on markers of iron metabolism in humans has not been investigated. We aimed to determine whether carnosine supplementation has an effect on iron parameters in overweight and obese, otherwise healthy adults. We included 26 participants, who were randomly allocated to receive 1 g carnosine (n = 14) or identical placebo (n = 12) twice daily for 12 weeks. Iron parameters including iron, ferritin, transferrin, soluble transferrin receptor, total iron binding capacity and iron saturation were measured in serum or plasma by standard commercial assays. Carnosine supplementation decreased plasma soluble transferrin receptor compared to placebo (mean change difference ± standard error: - 0.07 ± 0.03 mg/l, p = 0.04). None of the other iron parameters were different between carnosine and placebo groups. At follow-up, soluble transferrin receptor was associated inversely with urinary carnosine concentrations and positively with serum carnosinase-1 activity (both p < 0.02). Our findings suggest that carnosine may modulate iron metabolism in high-risk groups which could ameliorate insulin resistance and prevent type 2 diabetes. Larger human clinical trials are required to confirm our results.

RESUMO

AIMS: To examine reports of anaphylaxis in Australasia from consumption of packaged food products with or without precautionary allergen labelling (PAL), where the known allergen triggers were not a listed ingredient. METHODS: A questionnaire was sent to all members of the Australasian Society of Clinical Immunology and Allergy (n = 548). Participants were asked to complete a survey reporting whether they have had seen any patients over the last 3 months reporting anaphylaxis following ingestion of a packaged food where the suspected food allergen was not a listed ingredient. RESULTS: Of the n = 548 members approached, n = 198 responded (response rate 36.1%).There were 14 reports of anaphylaxis to packaged foods (where the suspected allergen was not a listed ingredient), which met the case definition from a total of 198 respondents over the 9-month period. Of those reactions, 50.0% (confidence interval 95% 21-78) were reported from foods that did not have a PAL statement, and 50.0% (confidence interval 95% 21-78) were due to peanuts. CONCLUSION: Anaphylaxis to undeclared allergens was not rare and did not appear to depend on whether the product was labelled with precautionary advice. There is currently no reliable labelling system that can inform food-allergic consumers of safer food choices. Improvements in the regulation of food labelling with PAL are required.

RESUMO

We have previously shown that an isoenergetic low advanced glycation end products (AGEs) diet matched for macronutrient content improved insulin sensitivity compared to high AGE diet. Here, we evaluated the differences in micronutrient intake of these two dietary patterns and if they could explain differences in insulin sensitivity. Participants consumed the intervention diets each for 2 weeks with 4 weeks of habitual dietary intake (washout) in-between. Dietary analysis revealed that the high AGE diet contained greater levels of retinol equivalents (RE) (478.9 + 151.3 µg/day versus 329.0 + 170.0 µg/day; p < .006), vitamin A (806.3 + 223.5 (µg RE)/day versus 649.1 + 235.8 (µg RE)/day; p < .05) and thiamine (2.3 + 0.6 mg/day versus 1.6 + 0.4 mg/day; p = .014) compared to the low AGE diet. The changes in polyunsaturated fat, retinol, vitamin A and thiamine did not correlate with changes in insulin sensitivity (all p > .1) therefore are unlikely to explain observed changes in insulin sensitivity.

RESUMO

BACKGROUND: Interprofessional education (IPE) requires health students to learn with, from and about each other in order to develop a modern workforce with client-centred care at its core. Despite the client centred focus of IPE, training programs often utilize standard approaches across student cohorts without consideration of discipline, sociodemographic and personality variability that attract students to different health disciplines. Knowing the students who engage in IPE to tailor training may prove as beneficial as knowing the client to delivered individualized client centred care in interprofessional practice (IPP). This research investigates whether students commencing undergraduate nursing and paramedicine degrees ener training with existing demographic and personality differences and, if these are associated with different attitudes towards health care teams and interprofessional education. METHOD: This online study recruited 160 nursing and 50 paramedicine students in their first week of their undergraduate course. Students completed questionnaires regarding their background, personality (General Perceived Self Esteem Scale, International Mini Markers) and the attitudes towards health care teams scale (ATHCTS) and interprofessional education perception scale (IEPS). RESULTS: Results show that commencing nursing and paramedicine students are demographically different on education, gender, speaking a language other than English at home (LOTE) and their own experience with healthcare. The results further demonstrate that LOTE, discipline being studied and personality factors play a role in perceptions regarding interprofessional training whilst discipline being studied impacted on attitudes towards health care teams in the workforce. CONCLUSION: These results highlight a number of existing personal and psychological differences between individuals who choose to train in these selected professions. This suggests a need for tertiary education IPE programs to move towards tailoring their education to value this student diversity in the same client centred manner that students are asked to develop clinically.

RESUMO

Strong leadership from heads of state is needed to meet national commitments to the UN political declaration on non-communicable diseases (NCDs) and to achieve the goal of a 25% reduction in premature NCD mortality by 2025 (the 25 by 25 goal). A simple, phased, national response to the political declaration is suggested, with three key steps: planning, implementation, and accountability. Planning entails mobilisation of a multisectoral response to develop and support the national action plan, and to build human, financial, and regulatory capacity for change. Implementation of a few priority and feasible cost-effective interventions for the prevention and treatment of NCDs will achieve the 25 by 25 goal and will need only few additional financial resources. Accountability incorporates three dimensions: monitoring of progress, reviewing of progress, and appropriate responses to accelerate progress. A national NCD commission or equivalent, which is independent of government, is needed to ensure that all relevant stakeholders are held accountable for the UN commitments to NCDs.

RESUMO

It has been postulated that chronic exposure to high levels of advanced glycation end products (AGEs), in particular from dietary sources, can impair insulin secretion. In the present study, we investigated the cross-sectional relationship between AGEs and acute insulin secretion during an intravenous glucose tolerance test (IVGTT) and following a 75 g oral glucose tolerance test (OGTT) in healthy humans. We report the cross-sectional association between circulating AGE concentrations and insulin secretory function in healthy humans (17 F: 27 M, aged 30 ± 10 years) with a wide range of BMI (24.6-31.0 kg/m(2)). Higher circulating concentrations of AGEs were related to increased first phase insulin secretion during IVGTT (r = 0.43; p < 0.05) and lower 2-h glucose concentrations during OGTT (r = -0.31; p < 0.05). In addition, fasting (r = -0.36; p < 0.05) and 2-h glucose concentrations were negatively related to circulating levels of soluble receptor for AGE (RAGE) isoforms (r = -0.39; p < 0.01). In conclusion, in healthy humans, we show a cross-sectional association between advanced glycation end products and acute insulin secretion during glucose tolerance testing.

RESUMO

BACKGROUND: High levels of circulating advanced glycation end products (AGEs) can initiate chronic low-grade activation of the immune system (CLAIS) with each of these factors independently associated with cardiovascular (CV) morbidity and mortality. Therefore, our objective was to characterize the relationship between serum AGEs, CLAIS and other risk factors for CV disease in normotensive non-diabetic individuals. METHODS: We measured body mass index (BMI), waist-to-hip ratio (WHR), blood pressure, lipid and glucose profile in 44 non-diabetic volunteers (17 female, 27 males). Carboxymethyl-lysine (CML) was measured by ELISA as a marker for circulating AGEs and NF-κB p65 activity as an inflammatory marker by DNA-binding in peripheral blood mononuclear cells lysates (PBMC). RESULTS: Plasma CML concentrations were related to diastolic blood pressure (r=-0.51, p<0.01) independently of age, sex, BMI and WHR (p<0.05). Diastolic blood pressure was also related to NF-κB activity in PBMC (r=0.47, p<0.01) before and after adjustment for age, sex, BMI and WHR (p<0.05). Plasma CML concentrations were related to the pulse pressure before (r=0.42; p<0.05) and after adjustment for age, sex, BMI and waist (p<0.05). Neither CML nor NF-κB activity were related to systolic blood pressure (both p=ns). Plasma CML concentrations were not associated with plasma lipid or glucose concentrations (all p=ns). CONCLUSIONS: Plasma AGE levels and NF-κB activity in PBMC were independent determinants of diastolic and pulse pressure in healthy normotensive individuals. This association suggests a role for AGEs in the etiology of hypertension, possibly via the initiation of CLAIS and aortic stiffening.

RESUMO

BACKGROUND: Gestational diabetes mellitus (GDM) - a transitory form of diabetes first recognised during pregnancy complicates between < 1% and 28% of all pregnancies. GDM has important short and long-term health consequences for both the mother and her offspring. To prevent adverse pregnancy outcomes and to prevent or delay future onset of type 2 diabetes in mother and offspring, timely detection, optimum treatment, and preventive postpartum care and follow-up is necessary. However the area remains grossly under-prioritised. METHODS: To investigate determinants and barriers to GDM care from initial screening and diagnosis to prenatal treatment and postpartum follow-up, a PubMed database search to identify quantitative and qualitative studies on the subject was done in September 2012. Fifty-eight relevant studies were reviewed. RESULTS: Adherence to prevailing GDM screening guidelines and compliance to screening tests seems sub-optimal at best and arbitrary at worst, with no clear or consistent correlation to health care provider, health system or client characteristics. Studies indicate that most women express commitment and motivation for behaviour change to protect the health of their unborn baby, but compliance to recommended treatment and advice is fraught with challenges, and precious little is known about health system or societal factors that hinder compliance and what can be done to improve it. A number of barriers related to health care provider/system and client characteristics have been identified by qualitative studies. Immediately following a GDM pregnancy many women, when properly informed, desire and intend to maintain healthy lifestyles to prevent future diabetes, but find the effort challenging. Adherence to recommended postpartum screening and continued lifestyle modifications seems even lower. Here too, health care provider, health system and client related determinants and barriers were identified. Studies reveal that sense of self-efficacy and social support are key determinants. CONCLUSIONS: The paper identifies and discusses determinants and barriers for GDM care, fully recognising that these are highly dependent on the context.

RESUMO

Obesity is an emerging problem for African migrants in Australia, but few prevention programs incorporate their cultural beliefs and values. This study reports on the application of community capacity-building and empowerment principles in 4 workshops with Sudanese families in Australia. Workshop participants prioritized health behaviors, skill and knowledge gaps, and environments for change to identify culturally centered approaches to health promotion. The workshops highlighted a need for culturally and age-appropriate interventions that build whole-of-family skills and knowledge around the positive effects of physical activity and nutrition to improve health within communities while reducing intergenerational and gender role family conflicts.

RESUMO

Background: Cardiovascular diseases (CVDs) are a significant cause of morbidity and mortality worldwide, resulting in a high socioeconomic burden. Growing evidence has shown a link between oral diseases and several chronic conditions including CVDs. The focus of this review is to investigate and summaries the evidence surrounding oral health interventions and their potential impact on reducing both the risk and/or severity of CVDs. Methods: A scoping review was conducted to examine oral health interventions for managing CVD outcomes and risks. The review adhered to the Joanna Briggs Institute (JBI) framework for evidence synthesis and followed the reporting standards outlined by the Preferred Reporting Items for Systematic Reviews and Meta-analysis- extension to Scoping Review (PRISMA-ScR). A systematic search across EBSCOhost, PubMed, and Scopus databases from 2012 to 2024 was utilized to identify relevant studies. Inclusion criteria focused on English language articles with a sample size of at least 50, evaluating the impact of oral health interventions on CVD outcomes. Results: Out of the initial 2,154 studies identified in the search, 12 studies met the inclusion and exclusion criteria and were included in the final analysis. Overall, the studies revealed that along with surgical and non-surgical periodontal therapy, regular oral hygiene care practices, including toothbrushing, tongue brushing, and flossing, significantly reduced the risk of cardiovascular events and mortality. These interventions in patients with or without CVD baseline have shown a decrease in CVD risk markers as well as a reduction in bacterial colonization. Similarly, consistent oral hygiene routines, combined with regular dental visits, were associated with a lower risk of heart failure and CVD risk mortality. Conclusion: The evidence extracted from this review suggests that periodontal therapy, regular dental cleaning, and re-enforcing of oral health regimes can stabilize oral health conditions and subsequently improve CVD progression/risks. However, limited to no evidence exists regarding the therapeutic effects of oral health promotion in managing CVD markers and its direct impact on disease outcomes, warranting further investigation.

RESUMO

INTRODUCTION: Chronic disease self-management (CDSM) is a vital component of congestive heart failure (CHF) programmes. Recent CHF guidelines have downgraded CDSM programmes citing a lack of gold-standard evidence. This protocol describes the aims and methods of a systematic review to collate and synthesise the published research evidence to determine the effectiveness of CDSM programmes and interventions for patients treated for CHF. METHODS: Medline, PubMed, Embase, CENTRAL, CINAHL, Cochrane Central Register of Controlled Trials, PsycINFO, SCOPUS, Web of Science, the Science Citation Index and registers of clinical trials will be searched from 1966 to 2024. In addition, the reference lists of shortlisted articles will be reviewed. Randomised controlled trials, with case management interventions of CDSM and CHF with reported major adverse cardiovascular events (MACEs), will be extracted and analysed. There is no restriction on language. Study protocol template developed from Cochrane Collaboration and Reporting adheres to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol guidelines for systematic review and meta-analyses 2020. Two independent authors will apply inclusions and exclusion criteria to limit article search and assess bias and certainty of evidence rating. Data extraction and study description of included studies will include quality appraisal of studies and quantitative synthesis of data will then be undertaken to ascertain evidence for the study aims. Subgroup analyses will be conducted for different CDSM programmes. The primary outcome will be a significant change in MACE parameters between intervention and control arms. Meta-analysis will be conducted using statistical software, if feasible. ETHICS AND DISSEMINATION: Ethics approval is not sought as the study is not collecting primary patient data. The results of this study will be disseminated through peer-reviewed scientific journals and also presented to audiences through meetings and scientific conferences.
