What do antenatal care providers understand and do about oral health care during pregnancy: a cross-sectional survey in New South Wales, Australia.

BACKGROUND: There is mounting evidence to support the lack of awareness among pregnant women about health consequences and long term risks associated with poor oral hygiene during pregnancy. A recognised and important point of influence is their interaction with health professionals, particularly when receiving Antenatal Care. However, there is limited evidence about the perceptions of ANC providers in Australia toward the provision of perinatal oral healthcare. This study was undertaken to explore the knowledge, attitudes and practices of Antenatal Care (ANC) providers in New South Wales (NSW), Australia providing perinatal oral healthcare and to identify barriers to and predictors of their practices in this area. METHODS: A cross sectional survey was undertaken of ANC providers (general practitioners, obstetricians/gynaecologists and midwives) practising in NSW, Australia. Participants were recruited through their professional organisations via email, postal mail, and networking at conferences. The survey addressed the domains of knowledge, attitude, barriers and practices towards oral healthcare, along with demographics. Data was entered into SPSS software and analysed using descriptive and inferential statistics. RESULTS: A total of 393 surveys (17.6% response rate) were completed comprising 124 general practitioners, 74 obstetricians/gynaecologists and 195 midwives. The results showed limited knowledge among ANC providers regarding the impact of poor maternal oral health on pregnancy/infant outcomes. Most (99%) participants agreed that maternal oral health was important yet few were discussing the importance of oral health or advising women to visit a dentist (16.4-21.5%). Further, less than a third felt they had the skills to provide oral health advice during pregnancy. ANC providers who were more knowledgeable about maternal oral health, had training and information in this area and greater experience, were more likely to engage in practices addressing the oral health of pregnant women. CONCLUSION: The findings suggest that ANC providers in NSW are not focussing on oral health with pregnant women. ANC providers seem willing to discuss oral health if they have appropriate education/training and information in this area. Further research at a national level is required to confirm whether these findings are similar in all Australian states.

MIGRATORY IMPLICATIONS FOR CORONARY HEART DISEASE RISK PREVENTION IN ASIAN INDIANS: EVIDENCE FROM THE LEADING HEALTH INDICATORS.

OBJECTIVEctives of this descriptive comparative study were to (1) review data obtained from the World Health Organisation Statistical Information System (WHOSIS) database relating to the prevalence of risk factors for coronary heart disease (CHD) among Indians and Australians and (2) compare these data with published epidemiological studies of CHD riskfactors in adult migrant Asian Indians to provide a comprehensive and comparable assessment of risk factors relating to CHD and the mortality attributable to these risk factors. Design: ThDESIGNdy was undertaken using a database search and integrative review methodology. Data were obtained for comparison of CHD risk factors between Indians and Australians using the WHOSIS database. For the integrative review the MEDLINE, CINAHL, EMBASE, and Cochrane databases were searched using the keywords 'Migrants', 'Asian Indian', 'India', 'Migration', 'Immigration', 'Risk factors', and coronary heart disease. Two reviewers independently assessed the eligibility of the studies for inclusion in the review, the methodological quality and extracted details of eligible studies. Results from the integrative review on CHD risk factors in Asian Indians are presented in a narrative format, along with results from the WHOSIS database. Results: TRESULTSadjusted mortality for CHD was four times higher in migrant Asian Indians when compared to both the native population of the host country and migrants from other countries. Similarly when compared to migrants from other countries migrant Asian Indians had the highest prevalence of overweight individuals. Prevalence rates for hypercholesterolemia were up to 18.5 % among mgrant Asian Indians and migrant Asian Indian women had a higher prevalence of hypertriglyceridaemia compared to Caucasian females. Migrant Asian Indians also had a higher incidence of hypertension and upto 71 % of migrnt Asian Indian men did not meet current guidelines for participation in physical activity. Ethnic-specific prevalence of diabetes ranged from 6-7% among the normal weight to 19-33% among the obese migrant Asian Indians compared with non-Hispanic whites. ConclusionCONCLUSIONAsian Indians have an increased risk of CHD. Culturally sensitive strategies that recognise the effects of migration and extend beyond the health sector should be developed to target lifestyle changes in this high risk population.

Attribution of risk for coronary heart disease in a vulnerable immigrant population: a survey study.

BACKGROUND: Coronary heart disease (CHD) is a common and costly condition and is increasing at a higher rate among Asian Indians than among other ethnic groups. An understanding of how Asian Indians perceive their risk is important for health providers to develop culturally appropriate programs to raise awareness of the risk of CHD. OBJECTIVE: The aim of this survey was to investigate the attribution of risk factors for CHD among the Asian Indian community in Australia. METHODS: Asian Indian community leaders were recruited to provide their views of how their community perceived the risk of CHD. An online survey collected demographic data and information from the Illness Perception Questionnaire-Revised, which measures 6 domains of illness perception: timeline acute/chronic, consequences, emotional impact, personal control, treatment efficacy, and illness comprehension. RESULTS: An 84% response rate (n = 49) was achieved from Asian Indian community leaders. Heart disease and cancer were considered to be the illnesses of major concern. Participants indicated that people in their community perceived hereditary factors (90%), hypertension, stress or worry (84%), and aging (86%) as the major cause of their illnesses. Smoking, high blood pressure, and cholesterol were identified as being major risk factors for CHD. CONCLUSIONS: These data suggest that as well as strategies to address risk factors such as diet and exercise, stress management is an important issue to consider in developing community-based programs.

Models of care in nursing: a systematic review.

OBJECTIVE: This review investigated the effect of the various models of nursing care delivery using the diverse levels of nurses on patient and nursing outcomes. METHODS: All published studies that investigated patient and nursing outcomes were considered. Studies were included if the nursing delivery models only included nurses with varying skill levels. A literature search was performed using the following databases: Medline (1985-2011), CINAHL (1985-2011), EMBASE (1985 to current) and the Cochrane Controlled Studies Register (Issue 3, 2011 of Cochrane Library). In addition, the reference lists of relevant studies and conference proceedings were also scrutinised. Two reviewers independently assessed the eligibility of the studies for inclusion in the review, the methodological quality and extracted details of eligible studies. Data were analysed using the RevMan software (Nordic Cochrane Centre, Copenhagen, Denmark). RESULTS: Fourteen studies were included in this review. The results reveal that implementation of the team nursing model of care resulted in significantly decreased incidence of medication errors and adverse intravenous outcomes, as well as lower pain scores among patients; however, there was no effect of this model of care on the incidence of falls. Wards that used a hybrid model demonstrated significant improvement in quality of patient care, but no difference in incidence of pressure areas or infection rates. There were no significant differences in nursing outcomes relating to role clarity, job satisfaction and nurse absenteeism rates between any of the models of care. CONCLUSIONS: Based on the available evidence, a predominance of team nursing within the comparisons is suggestive of its popularity. Patient outcomes, nurse satisfaction, absenteeism and role clarity/confusion did not differ across model comparisons. Little benefit was found within primary nursing comparisons and the cost effectiveness of team nursing over other models remains debatable. Nonetheless, team nursing does present a better model for inexperienced staff to develop, a key aspect in units where skill mix or experience is diverse.

The role of clinical trial nurses: an Australian perspective.

Over the past two decades, the number of clinical trials conducted globally has increased thereby increasing demand for nurses working as Clinical Trial Nurses (CTNs), sometimes known as Clinical Research Nurses. The role and professional issues for these nurses in Australia has not been empirically formulated. Sixty-seven clinical trial nurses were surveyed nationally using a modified version of the Clinical Trials Nursing Questionnaire (CTNQ). Findings revealed the complex CTN role can include the coordination of the trials on one or more sites. This involves all domains listed in the questionnaire from protocol development, ethics approval applications, recruitment and consenting of participants in trials, to administering or assisting with treatments within the bounds of their practice code and the evaluation of protocols. Professional issues documented were: being undervalued in the nursing workforce, having no formal educational preparation for the role and minimal recognition in publications emanating from research in which they were involved. These nurses bring their practice knowledge to benefit research outcomes that may contribute to improving patient/client care.

Prevalence of obesity among migrant Asian Indians: a systematic review and meta-analysis.

OBJECTIVE: The objective of this review was to investigate the prevalence of obesity among migrant Asian Indians globally. The primary outcomes of interest included the incidence of obesity as measured objectively by body mass index (BMI), waist circumference, waist-to-hip ratio and body fat. METHODS: All published studies that investigated obesity rates in migrant Asian Indians were considered for inclusion in the review. Studies were included if they had more than 100 participants and reported objective measures of obesity. A literature search was performed using the following databases Medline (2000-10), Cumulative Index to Nursing and Allied Health Literature (2000-11), Excerpta Medica Database (2000-current) and the Cochrane Controlled Studies Register (Issue 1, 2011 of Cochrane Library). In addition, the reference lists of relevant studies and conference proceedings were also scrutinised. Two reviewers independently assessed the eligibility of the studies for inclusion in the review, the methodological quality and then extracted details of eligible studies. Data were analysed using the Review Manager software. RESULTS: Ten studies investigating the obesity indices in Asian Indians were eligible for this review. All ten trials that reported on BMI values demonstrated significantly higher BMI values among migrant Asian Indians when compared with other migrants and the native population (standardised mean difference 0.36; 95% confidence interval 0.30, 0.41). A greater proportion of Asian Indians had BMIs greater than or equal to 30 when compared with other ethnic groups. Up to 80% of the Asian Indian women had a waist circumference greater than the recommended value of 88 cm. CONCLUSIONS: Based on the available evidence, the obesity indices among migrant Asian Indians are significantly greater when compared with the native population and those living in India, particularly among women. This is likely to contribute to the high levels of diabetes and coronary heart disease in this population. Culturally appropriate strategies to reduce obesity, particularly abdominal obesity, in this ethnic group are urgently needed.

Long-acting octreotide treatment causes a sustained decrease in ghrelin concentrations but does not affect weight, behaviour and appetite in subjects with Prader-Willi syndrome.

OBJECTIVE: Ghrelin is secreted primarily by the stomach and circulates as both acylated and desacyl ghrelin. Acylated (but not desacyl) ghrelin stimulates appetite. Both concentrations are elevated in Prader-Willi syndrome (PWS), suggesting that ghrelin may contribute to hyperphagia and overweight in these subjects. We evaluated whether long-acting octreotide (Oct) decreases acylated and desacyl ghrelin concentrations, body mass, appetite and compulsive behaviour towards food in adolescents with PWS. DESIGN: A 56-week prospective, randomized, cross-over trial. METHODS: Nine subjects with PWS (age 14.6 (10.8-18.9) years, body mass index (BMI) Z-score +1.9 (0.6-3.0)) received either Oct (30 mg) or saline i.m. every 4 weeks for 16 weeks and were switched over to the other treatment after a 24-week washout period. RESULTS: Eight subjects completed the study. Oct caused a decrease in both acylated (-53%) and desacyl (-54%) fasting ghrelin concentrations (P<0.05) but did not significantly affect BMI. Oct had no significant effect on peptide YY concentrations, appetite or compulsive behaviour towards food. Oct caused a decrease in insulin-like growth factor-I concentrations, an increase in HbA1c and transient elevation of blood glucose in two subjects. Three subjects developed gallstones. CONCLUSIONS: Oct treatment caused a prolonged decrease in ghrelin concentrations in adolescents with PWS but did not improve body mass or appetite. Future intervention studies aiming at clarifying the role of ghrelin in PWS should focus on the administration of specific inhibitors of ghrelin secretion or ghrelin receptor activity that do not interfere with other appetite-regulating peptides.

Healthy Buddies: a novel, peer-led health promotion program for the prevention of obesity and eating disorders in children in elementary school.

OBJECTIVE: We designed and tested a novel health promotion program for elementary schools that was based on peer teaching from older to younger schoolchildren ("Healthy Buddies"). SUBJECTS AND METHODS: This prospective pilot study compared the effect of our program (2-3 hours/week, 21 weeks) in 2 Canadian elementary schools (intervention: n = 232 children, the whole school implementing the program; control: n = 151). Older students (4th through 7th grade) were given direct instruction from 1 intervention teacher and were paired with younger students (kindergarten through 3rd grade) for the whole school year. Students in 4th through 7th grade then acted as teachers for their younger "buddies." All lessons included 3 components of healthy living: nutrition, physical activity, and healthy body image. The students first learned how to be positive buddies and learned the 3 components of a healthy life. Thereafter, they learned how to overcome challenges to living a healthy life. Outcome measures (intervention and control schools at the beginning and end of the school year) included validated questionnaires that assessed healthy-living knowledge, behavior and attitude, a 9-minute fitness run, self-competence, body satisfaction, disordered eating symptoms, and anthropometry (BMI, blood pressure, and heart rate). RESULTS: Compared with control students, both older and younger intervention students showed an increase in healthy-living knowledge, behavior, and attitude scores and a smaller increase in systolic blood pressure. BMI and weight increased less in the intervention students in 4th through 7th grade and height more in the intervention students in kindergarten through 3rd grade. CONCLUSIONS: Our student-led curriculum improved knowledge not only in older schoolchildren but also in their younger buddies. It also decreased weight velocity in the older students. Student-led teaching may be an efficient, easy-to-implement way of promoting a healthy lifestyle from kindergarten to 7th grade.

Predictors of Intelligence after Temporal Lobectomy in Children with Epilepsy.

Performance on standardized measures of intelligence was examined before and after temporal lobectomy in 50 children and adolescents. Group results showed small positive changes in Performance IQ (PIQ), but not Verbal IQ (VIQ). Analyses of individual patients showed that 28% had a significant change in VIQ after surgery, half of whom showed improvements. Increases in VIQ were associated with older age at time of surgery, lower VIQ before surgery, and positive seizure outcome after surgery, whereas longer follow-up time was predictive of smaller change. Increases in PIQ were seen in 25% of patients, and decreases occurred in 8%. Predictors of postoperative change in PIQ were dual pathology and longer follow-up interval, both of which showed negative correlations. Enhanced intellectual function is not one of the benefits to be expected in the majority of children undergoing temporal lobectomy. Further studies are required to determine whether these conclusions may or may not be applied to other aspects of cognitive function.
