A codesigned integrated kidney and diabetes model of care improves patient activation among patients from culturally and linguistically diverse backgrounds.

BACKGROUND: Little is known about the relationship between patients' cultural and linguistic backgrounds and patient activation, especially in people with diabetes and chronic kidney disease (CKD). We examined the association between culturally and linguistically diverse (CALD) background and patient activation and evaluated the impact of a codesigned integrated kidney and diabetes model of care on patient activation by CALD status in people with diabetes and CKD. METHODS: This longitudinal study recruited adults with diabetes and CKD (Stage 3a or worse) who attended a new diabetes and kidney disease service at a tertiary hospital. All completed the patient activation measure at baseline and after 12 months and had demographic and clinical data collected. Patients from CALD backgrounds included individuals who spoke a language other than English at home, while those from non-CALD backgrounds spoke English only as their primary language. Paired t-tests compared baseline and 12-month patient activation scores by CALD status. RESULTS: Patients from CALD backgrounds had lower activation scores (52.1 ± 17.6) compared to those from non-CALD backgrounds (58.5 ± 14.6) at baseline. Within-group comparisons showed that patient activation scores for patients from CALD backgrounds significantly improved by 7 points from baseline to 12 months follow-up (52.1 ± 17.6-59.4 ± 14.7), and no significant change was observed for those from non-CALD backgrounds (58.5 ± 14.6-58.8 ± 13.6). CONCLUSIONS: Among patients with diabetes and CKD, those from CALD backgrounds report worse activation scores. Interventions that support people from CALD backgrounds with comorbid diabetes and CKD, such as the integrated kidney and diabetes model of care, may address racial and ethnic disparities that exist in patient activation and thus improve clinical outcomes. PATIENT OR PUBLIC CONTRIBUTION: Patients, caregivers and national consumer advocacy organisations (Diabetes Australia and Kidney Health Australia) codesigned a new model of care in partnership with healthcare professionals and researchers. The development of the model of care was informed by focus groups of patients and healthcare professionals and semi-structured interviews of caregivers and healthcare professionals. Patients and caregivers also provided a rigorous evaluation of the new model of care, highlighting its strengths and weaknesses.

A co-designed integrated kidney and diabetes model of care improves mortality, glycaemic control and self-care.

BACKGROUND: Current healthcare models are ill-equipped for managing people with diabetes and chronic kidney disease (CKD). We evaluated the impact of a new diabetes and kidney disease service (DKS) on hospitalization, mortality, clinical and patient-relevant outcomes. METHODS: Longitudinal analyses of adult patients with diabetes and CKD (Stages 3a-5) were performed using outpatient and hospitalization data from January 2015 to October 2018. Data were handled according to whether patients received the DKS intervention (n = 196) or standard care (n = 7511). The DKS provided patient-centred, coordinated multidisciplinary assessment and management of patients. Primary analyses examined hospitalization and mortality rates between the two groups. Secondary analyses evaluated the impact of the DKS on clinical target attainment, changes in estimated glomerular filtration rate (eGFR), glycated haemoglobin A1c (HbA1c), self-care and patient activation at 12 months. RESULTS: Patients who received the intervention had a higher hospitalization rate {incidence rate ratio [IRR] 1.20 [95% confidence interval (CI) 1.13-1.30]; P < 0.0001}, shorter median length of stay {2 days [interquartile range (IQR) 1-6] versus 4 days [IQR 1-9]; P < 0.0001} and lower all-cause mortality rate [IRR 0.4 (95% CI 0.29-0.64); P < 0.0001] than those who received standard care. Improvements in overall self-care [mean difference 2.26 (95% CI 0.83-3.69); P < 0.001] and in statin use and eye and feet examinations were observed. The mean eGFR did not change significantly after 12 months [mean difference 1.30 mL/min/1.73 m2 (95% CI -4.17-1.67); P = 0.40]. HbA1c levels significantly decreased by 0.40, 0.35, 0.34 and 0.23% at 3, 6, 9 and 12 months of follow-up, respectively. CONCLUSIONS: A co-designed, person-centred integrated model of care improved all-cause mortality, kidney function, glycaemic control and self-care for patients with diabetes and CKD.

The prevalence of mental illness in refugees and asylum seekers: A systematic review and meta-analysis.

BACKGROUND: Globally, the number of refugees and asylum seekers has reached record highs. Past research in refugee mental health has reported wide variation in mental illness prevalence data, partially attributable to methodological limitations. This systematic review aims to summarise the current body of evidence for the prevalence of mental illness in global refugee populations and overcome methodological limitations of individual studies. METHODS AND FINDINGS: A comprehensive search of electronic databases was undertaken from 1 January 2003 to 4 February 2020 (MEDLINE, MEDLINE In-Process, EBM Reviews, Embase, PsycINFO, CINAHL, PILOTS, Web of Science). Quantitative studies were included if diagnosis of mental illness involved a clinical interview and use of a validated assessment measure and reported at least 50 participants. Study quality was assessed using a descriptive approach based on a template according to study design (modified Newcastle-Ottawa Scale). Random-effects models, based on inverse variance weights, were conducted. Subgroup analyses were performed for sex, sample size, displacement duration, visa status, country of origin, current residence, type of interview (interpreter-assisted or native language), and diagnostic measure. The systematic review was registered with PROSPERO (CRD) 42016046349. The search yielded a result of 21,842 records. Twenty-six studies, which included one randomised controlled trial and 25 observational studies, provided results for 5,143 adult refugees and asylum seekers. Studies were undertaken across 15 countries: Australia (652 refugees), Austria (150), China (65), Germany (1,104), Italy (297), Lebanon (646), Nepal (574), Norway (64), South Korea (200), Sweden (86), Switzerland (164), Turkey (238), Uganda (77), United Kingdom (420), and the United States of America (406). The prevalence of posttraumatic stress disorder (PTSD) was 31.46% (95% CI 24.43-38.5), the prevalence of depression was 31.5% (95% CI 22.64-40.38), the prevalence of anxiety disorders was 11% (95% CI 6.75-15.43), and the prevalence of psychosis was 1.51% (95% CI 0.63-2.40). A limitation of the study is that substantial heterogeneity was present in the prevalence estimates of PTSD, depression, and anxiety, and limited covariates were reported in the included studies. CONCLUSIONS: This comprehensive review generates current prevalence estimates for not only PTSD but also depression, anxiety, and psychosis. Refugees and asylum seekers have high and persistent rates of PTSD and depression, and the results of this review highlight the need for ongoing, long-term mental health care beyond the initial period of resettlement.

Expression of the plasminogen system in the physiological mouse ovary and in the pathological polycystic ovary syndrome (PCOS) state.

BACKGROUND: The fibrinolytic system and its inhibitors play a number of roles, apart from their function in blood haemostasis and thrombosis, namely in ovarian folliculogenesis and in ovulation. Plasminogen is converted to active plasmin at the time of follicular rupture through a decrease in plasminogen activator inhibitor-1 (PAI-1) and an increase in plasminogen activators. Oligo-/anovulation and follicle arrest are key characteristics of PCOS, but studies evaluating fibrinolytic/proteolytic markers within human or animal PCOS ovaries are lacking. We aimed to investigate and compare the expression and distribution of the plasminogen system markers in PCOS and control ovaries. METHODS: A hyperandrogenised PCOS mouse model was used that mimics the ovarian, endocrine and metabolic features of the human condition. Immunohistochemistry and digital image analysis were used to investigate and compare fibrinolytic/proteolytic markers plasminogen, plasminogen/plasmin, tissue plasminogen activator, urokinase plasminogen activator and inhibitor PAI-1 in PCOS and control ovaries. Student's t-test was used to compare data sets for normally distributed data and Wilcoxon-Mann Whitney test for non-normally distributed data. RESULTS: We noted differences in the ovarian distribution of PAI-1 that was expressed throughout the PCOS ovary, unlike the peripheral distribution observed in control ovaries. Plasminogen was present in small follicles only in PCOS ovaries but not in small follicles of control ovaries. When we assessed and compared PAI-1 expression within follicles of different developmental stages we also noted significant differences for both the PCOS and control ovaries. While we noted differences in distribution and expression within specific ovarian structures, no differences were noted in the overall ovarian expression of markers assessed between acyclical PCOS mice and control mice at the diestrus stage of the estrous cycle. CONCLUSIONS: Our novel study, that comprehensively assessed the fibrinolytic/proteolytic system in the mouse ovary, showed the expression, differential localisation and a potential role for the plasminogen system in the physiological mouse ovary and in PCOS. Androgens may be involved in regulating expression of the ovarian plasminogen system. Further studies evaluating these markers at different time-points of ovulation may help to further clarify both physiological and potential pathological actions these markers play in ovulatory processes distorted in PCOS.

Gestational weight gain across continents and ethnicity: systematic review and meta-analysis of maternal and infant outcomes in more than one million women.

BACKGROUND: The association between Institute of Medicine (IOM) guidelines and pregnancy outcomes across ethnicities is uncertain. We evaluated the associations of gestational weight gain (GWG) outside 2009 IOM guidelines, with maternal and infant outcomes across the USA, western Europe and east Asia, with subgroup analyses in Asia. The aim was to explore ethnic differences in maternal prepregnancy body mass index (BMI), GWG and health outcomes across these regions. METHODS: Systematic review, meta-analysis and meta-regression of observational studies were used for the study. MEDLINE, MEDLINE In-Process, Embase and all Evidence-Based Medicine (EBM) Reviews were searched from 1999 to 2017. Studies were stratified by prepregnancy BMI category and total pregnancy GWG. Odds ratio (ORs) 95% confidence intervals (CI) applied recommended GWG within each BMI category as the reference. Primary outcomes were small for gestational age (SGA), preterm birth and large for gestational age (LGA). Secondary outcomes were macrosomia, caesarean section and gestational diabetes. RESULTS: Overall, 5874 studies were identified and 23 were included (n = 1,309,136). Prepregnancy overweight/obesity in the USA, Europe and Asia was measured at 42%, 30% and 10% respectively, with underweight 5%, 3% and 17%. GWG below guidelines in the USA, Europe and Asia was 21%, 18% and 31%, and above was 51%, 51% and 37% respectively. Applying regional BMI categories in Asia showed GWG above guidelines (51%) was similar to that in the USA and Europe. GWG below guidelines was associated with a higher risk of SGA (USA/Europe [OR 1.51; CI 1.39, 1.63]; Asia [1.63; 1.45, 1.82]) and preterm birth (USA/Europe [1.35; 1.17, 1.56]; Asia [1.06; 0.78, 1.44]) than GWG within guidelines. GWG above guidelines was associated with a higher risk of LGA (USA/Europe [1.93; 1.81, 2.06]; Asia [1.68; 1.51 , 1.87]), macrosomia (USA/Europe [1.87; 1.70, 2.06]; Asia [2.18; 1.91, 2.49]) and caesarean (USA/Europe [1.26; 1.21, 1.33]; Asia [1.37; 1.30, 1.45]). Risks remained elevated when regional BMI categories were applied for GWG recommendations. More women in Asia were categorised as having GWG below guidelines using World Health Organization (WHO) (60%) compared to regional BMI categories (16%), yet WHO BMI was not accompanied by increased risks of adverse outcomes. CONCLUSIONS: Women in the USA and western Europe have higher prepregnancy BMI and higher rates of GWG above guidelines than women in east Asia. However, when using regional BMI categories in east Asia, rates of GWG above guidelines are similar across the three continents. GWG outside guidelines is associated with adverse outcomes across all regions. If regional BMI categories are used in east Asia, IOM guidelines are applicable in the USA, western Europe and east Asia.

Inter-related effects of insulin resistance, hyperandrogenism, sympathetic dysfunction and chronic inflammation in PCOS.

OBJECTIVE: Insulin resistance, hyperandrogenism, sympathetic dysfunction and chronic low-grade inflammation may act together in a vicious cycle in the pathophysiology of PCOS. However, the inter-relationships of these components are not fully understood. We aimed to study these mechanisms in the pathophysiology of PCOS. PARTICIPANTS AND METHODS: Premenopausal women with PCOS (Rotterdam diagnostic criteria) and without PCOS were recruited from a community setting into a cross-sectional substudy within a randomized control trial. Insulin resistance (fasting insulin and glucose), hyperandrogenism (testosterone, sex hormone-binding globulin [SHBG] and Free Androgen Index [FAI]), muscle sympathetic nerve activity (MSNA) and markers of chronic low-grade inflammation (high sensitivity C-reactive protein [hs-CRP] and high molecular weight adiponectin [HMW-adiponectin]) were measured. RESULTS: Forty-nine women with PCOS (mean age 30 ± 6 mean BMI 29 ± 5) and 23 controls (mean age 29 ± 8 mean BMI 33 ± 7) with included in this analysis. MSNA and testosterone level were most significantly associated with PCOS status, after adjustment for age and BMI. In women with PCOS, markers of sympathetic activity correlated inversely with HMW-adiponectin and HMW-adiponectin correlated inversely with FAI. Testosterone and FAI both correlated positively with insulin resistance in women PCOS. CONCLUSION: Sympathetic dysfunction and hyperandrogenism are significantly associated with PCOS. Chronic low-grade inflammation potentially mediates the effect of sympathetic dysfunction on hyperandrogenism and insulin resistance.

Fracture risk in young and middle-aged adults with type 1 diabetes mellitus: A systematic review and meta-analysis.

BACKGROUND: Type 1 diabetes mellitus (T1DM) is associated with skeletal fragility. While previous meta-analyses have demonstrated an increased risk of fracture in individuals with T1DM, little is known about fracture risk in T1DM, in the absence of age-related confounders. AIMS: To determine the risk of fracture in young and middle-aged adults with T1DM aged 18-50 years old. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Ovid MEDLINE, PubMed, EMBASE, EBM reviews and relevant conference abstracts. STUDY INCLUSION CRITERIA: Studies of adults aged between 18-50 years with type 1 diabetes mellitus, with reported fracture outcomes. PRIMARY OUTCOMES: Incident or prevalent fracture. RESULTS: Six studies were included in the meta-analysis. A total of 1724 fractures occurred in 35 925 patients with T1DM and 48 253 fractures occurred in 2 455 016 controls. RR for all fractures was 1.88 (95% CI 1.52-2.32, P < .001). Fifty-six hip fractures occurred among 34 707 patients with T1DM and 594 hip fractures occurred in 2 295 177 controls. The RR of hip fractures was 4.40 (95% CI 2.58-7.50, P < .001). Females and males with T1DM had a RR of 5.79 (95% CI 3.55-9.44, P < .001) and 3.67 (95% CI 2.10-6.41, P < .001), respectively. CONCLUSIONS: In the absence of age-related comorbidities, fracture risk remains significantly elevated in young and middle-aged adults with T1DM. Younger age does not mitigate against hip fracture risk in T1DM, and health professionals need to be aware of this risk. Further studies are needed to evaluate the mechanisms of fracture in T1DM.

Burden of cardiovascular risk factors and disease among patients with type 1 diabetes: results of the Australian National Diabetes Audit (ANDA).

BACKGROUND: Cardiovascular risk stratification is complex in type 1 diabetes. We hypothesised that traditional and diabetes-specific cardiovascular risk factors were prevalent and strongly associated with cardiovascular disease (CVD) among adults with type 1 diabetes attending Australian diabetes centres. METHODS: De-identified, prospectively collected data from patients with type 1 diabetes aged ≥ 18 years in the 2015 Australian National Diabetes Audit were analysed. The burden of cardiovascular risk factors [age, sex, diabetes duration, glycated haemoglobin (HbA1c), blood pressure, lipid profile, body mass index, smoking status, retinopathy, renal function and albuminuria] and associations with CVD inclusive of stroke, myocardial infarction, coronary artery bypass graft surgery/angioplasty and peripheral vascular disease were assessed. Restricted cubic splines assessed for non-linearity of diabetes duration and likelihood ratio test assessed for interactions between age, diabetes duration, centre type and cardiovascular outcomes of interest. Discriminatory ability of multivariable models were assessed with area under the receiver operating characteristic (ROC) curves. RESULTS: Data from 1169 patients were analysed. Mean (± SD) age and median diabetes duration was 40.0 (± 16.7) and 16.0 (8.0-27.0) years respectively. Cardiovascular risk factors were prevalent including hypertension (21.9%), dyslipidaemia (89.4%), overweight/obesity (56.4%), ever smoking (38.5%), albuminuria (31.1%), estimated glomerular filtration rate < 60 mL/min/1.73 m2 (10.3%) and HbA1c > 7.0% (53 mmol/mol) (81.0%). Older age, longer diabetes duration, smoking and antihypertensive therapy use were positively associated with CVD, while high density lipoprotein-cholesterol and diastolic blood pressure were negatively associated (p < 0.05). Association with CVD and diabetes duration remained constant until 20 years when a linear increase was noted. Longer diabetes duration also had the highest population attributable risk of 6.5% (95% CI 1.4, 11.6). Further, the models for CVD demonstrated good discriminatory ability (area under the ROC curve 0.88; 95% CI 0.84, 0.92). CONCLUSIONS: Cardiovascular risk factors were prevalent and strongly associated with CVD among adults with type 1 diabetes attending Australian diabetes centres. Given the approximate J-shaped association between type 1 diabetes duration and CVD, the impact of cardiovascular risk stratification and management before and after 20 years duration needs to be further assessed longitudinally. Diabetes specific cardiovascular risk stratification tools incorporating diabetes duration should be an important consideration in future guideline development.

Patient reported barriers are associated with low physical and mental well-being in patients with co-morbid diabetes and chronic kidney disease.

BACKGROUND: Little is known about how patient reported barriers to health care impact the quality of life (HRQoL) of patients with comorbid disease. We investigated patient reported barriers to health care and low physical and mental well-being among people with diabetes and chronic kidney disease (CKD). METHODS: Adults with diabetes and CKD (estimated Glomerular Filtration Rate < 60 ml/min/1.73m2) were recruited and completed a questionnaire on barriers to health care, the 12-Item HRQoL Short Form Survey and clinical assessment. Low physical and mental health status were defined as mean scores < 50. Logistic regression models were used. RESULTS: Three hundred eight participants (mean age 66.9 ± 11 years) were studied. Patient reported 'impact of the disease on family and friends' (OR 2.07; 95% CI 1.14 to 3.78), 'feeling unwell' (OR 4.23; 95% CI 1.45 to 12.3) and 'having other life stressors that make self-care a low priority' (OR 2.59; 95% CI 1.20 to 5.61), were all associated with higher odds of low physical health status. Patient reported 'feeling unwell' (OR 2.92; 95% CI 1.07 to 8.01), 'low mood' (OR 2.82; 95% CI 1.64 to 4.87) and 'unavailability of home help' (OR 1.91; 95% CI 1.57 to 2.33) were all associated with higher odds of low mental health status. The greater the number of patient reported barriers the higher the odds of low mental health but not physical health status. CONCLUSIONS: Patient reported barriers to health care were associated with lower physical and mental well-being. Interventions addressing these barriers may improve HRQoL among people with comorbid diabetes and CKD.

The association between patient activation and self-care practices: A cross-sectional study of an Australian population with comorbid diabetes and chronic kidney disease.

OBJECTIVE: This study aimed to examine the association between performance of self-care activities and patient or disease factors as well as patient activation levels in patients with diabetes and chronic kidney disease (CKD) in Australia. METHODS: A cross-sectional study was conducted among adults with diabetes and CKD (eGFR <60 mL/min/1.73m2 ) who were recruited from renal and diabetes clinics of four tertiary hospitals in Australia. Demographic and clinical data were collected, as well as responses to the Patient Activation Measure (PAM) and the Summary of Diabetes Self-Care Activities (SDSCA) scale. Regression analyses were performed to determine the relationship between activation and performance of self-care activities. RESULTS: A total of 317 patients (70% men) with a mean age of 66.9 (SD=11.0) years participated. The mean (SD) PAM and composite SDSCA scores were 57.6 (15.5) % (range 0-100) and 37.3 (11.2) (range 0-70), respectively. Younger age, being male, advanced stages of CKD and shorter duration of diabetes were associated with lower scores in one or more self-care components. Patient activation was positively associated with the composite SDSCA score, and in particular the domains of general diet and blood sugar checking (P<.05), but not specific diet, exercising and foot checking. CONCLUSION: In people with diabetes and CKD, a high level of patient activation was positively associated with a higher overall level of self-care. Our results identify subgroups of people who may benefit from tailored interventions to further improve their health outcomes. Further prospective studies are warranted to confirm present findings.

Association of Gestational Weight Gain With Maternal and Infant Outcomes: A Systematic Review and Meta-analysis.

IMPORTANCE: Body mass index (BMI) and gestational weight gain are increasing globally. In 2009, the Institute of Medicine (IOM) provided specific recommendations regarding the ideal gestational weight gain. However, the association between gestational weight gain consistent with theIOM guidelines and pregnancy outcomes is unclear. OBJECTIVE: To perform a systematic review, meta-analysis, and metaregression to evaluate associations between gestational weight gain above or below the IOM guidelines (gain of 12.5-18 kg for underweight women [BMI <18.5]; 11.5-16 kg for normal-weight women [BMI 18.5-24.9]; 7-11 kg for overweight women [BMI 25-29.9]; and 5-9 kg for obese women [BMI ≥30]) and maternal and infant outcomes. DATA SOURCES AND STUDY SELECTION: Search of EMBASE, Evidence-Based Medicine Reviews, MEDLINE, and MEDLINE In-Process between January 1, 1999, and February 7, 2017, for observational studies stratified by prepregnancy BMI category and total gestational weight gain. DATA EXTRACTION AND SYNTHESIS: Data were extracted by 2 independent reviewers. Odds ratios (ORs) and absolute risk differences (ARDs) per live birth were calculated using a random-effects model based on a subset of studies with available data. MAIN OUTCOMES AND MEASURES: Primary outcomes were small for gestational age (SGA), preterm birth, and large for gestational age (LGA). Secondary outcomes were macrosomia, cesarean delivery, and gestational diabetes mellitus. RESULTS: Of 5354 identified studies, 23 (n = 1 309 136 women) met inclusion criteria. Gestational weight gain was below or above guidelines in 23% and 47% of pregnancies, respectively. Gestational weight gain below the recommendations was associated with higher risk of SGA (OR, 1.53 [95% CI, 1.44-1.64]; ARD, 5% [95% CI, 4%-6%]) and preterm birth (OR, 1.70 [1.32-2.20]; ARD, 5% [3%-8%]) and lower risk of LGA (OR, 0.59 [0.55-0.64]; ARD, -2% [-10% to -6%]) and macrosomia (OR, 0.60 [0.52-0.68]; ARD, -2% [-3% to -1%]); cesarean delivery showed no significant difference (OR, 0.98 [0.96-1.02]; ARD, 0% [-2% to 1%]). Gestational weight gain above the recommendations was associated with lower risk of SGA (OR, 0.66 [0.63-0.69]; ARD, -3%; [-4% to -2%]) and preterm birth (OR, 0.77 [0.69-0.86]; ARD, -2% [-2% to -1%]) and higher risk of LGA (OR, 1.85 [1.76-1.95]; ARD, 4% [2%-5%]), macrosomia (OR, 1.95 [1.79-2.11]; ARD, 6% [4%-9%]), and cesarean delivery (OR, 1.30 [1.25-1.35]; ARD, 4% [3%-6%]). Gestational diabetes mellitus could not be evaluated because of the nature of available data. CONCLUSIONS AND RELEVANCE: In this systematic review and meta-analysis of more than 1 million pregnant women, 47% had gestational weight gain greater than IOM recommendations and 23% had gestational weight gain less than IOM recommendations. Gestational weight gain greater than or less than guideline recommendations, compared with weight gain within recommended levels, was associated with higher risk of adverse maternal and infant outcomes.

Preventing Weight Gain in Women in Rural Communities: A Cluster Randomised Controlled Trial.

BACKGROUND: Obesity is reaching epidemic proportions in both developed and developing countries. Even modest weight gain increases the risk for chronic illness, yet evidence-based interventions to prevent weight gain are rare. This trial will determine if a simple low-intensity intervention can prevent weight gain in women compared to general health information. METHODS AND FINDINGS: We conducted a 1-yr pragmatic, cluster randomised controlled trial in 41 Australian towns (clusters) randomised using a computer-generated randomisation list for intervention (n = 21) or control (n = 20). Women aged 18 to 50 yr were recruited from the general population to receive a 1-yr self-management lifestyle intervention (HeLP-her) consisting of one group session, monthly SMS text messages, one phone coaching session, and a program manual, or to a control group receiving one general women's health education session. From October 2012 to April 2014 we studied 649 women, mean age 39.6 yr (+/- SD 6.7) and BMI of 28.8 kg/m(2) (+/- SD 6.9) with the primary outcome weight change between groups at 1 yr. The mean change in the control was +0.44 kg (95% CI -0.09 to 0.97) and in the intervention group -0.48 kg (95% CI -0.99 to 0.03) with an unadjusted between group difference of -0.92 kg (95% CI -1.67 to -0.16) or -0.87 kg (95% CI -1.62 to -0.13) adjusted for baseline values and clustering. Secondary outcomes included improved diet quality and greater self-management behaviours. The intervention appeared to be equally efficacious across all age, BMI, income, and education subgroups. Loss to follow-up included 23.8% in the intervention group and 21.8% in the control group and was within the anticipated range. Limitations include lack of sensitive tools to measure the small changes to energy intake and physical activity. Those who gained weight may have been less inclined to return for 1 yr weight measures. CONCLUSIONS: A low intensity lifestyle program can prevent the persistent weight gain observed in women. Key features included community integration, nonprescriptive simple health messages, small changes to behaviour, low participant burden, self-weighing, and delivery including a mix of group, phone, and SMS text reminders. The findings support population strategies to halt the rise in obesity prevalence.

Comprehensive Assessment of the Hemostatic System in Polycystic Ovarian Syndrome.

Polycystic ovarian syndrome (PCOS) affects 12 to 19% of women and has reproductive and metabolic features (endothelial dysfunction, increased diabetes, and cardiovascular risk factors). It also appears to have altered coagulation and fibrinolysis with a prothrombotic state with epidemiological evidence of increased venous thromboembolism. We aimed to comprehensively assess hemostasis in women with PCOS versus control women. In an established case-control cohort of lean, overweight, and obese women with (n = 107) and without PCOS (n = 67), with existing measures of plasminogen activator inhibitor 1 (PAI-1), asymmetric dimethylarginine (ADMA), hormonal, and metabolic markers, we also assessed prothrombin fragments 1 and 2 (PF1 & 2), plasminogen, tissue plasminogen activator (tPA), and thrombin generation (TG). Higher levels of ADMA (0.70 vs. 0.39 µmol/L, p < 0.01), PAI-1 (4.80 vs. 3.66 U/mL, p < 0.01), and plasminogen (118.39 vs. 108.46%, p < 0.01) were seen in PCOS versus controls, and persisted after adjustment for age and body mass index (BMI). PF1 & 2 was marginally lower (180.0 vs. 236.0 pmol/L, p = 0.05), whereas tPA and TG were not different between groups, after adjustment for age and BMI. Significant relationships were observed between hormonal and metabolic factors with ADMA and PAI-1. We demonstrate impaired fibrinolysis in PCOS. In the context of abnormal endothelial function and known hormonal and metabolic abnormalities, this finding may underpin an increased risk of cardiovascular disease and venous thrombosis in PCOS.

Contemporary type 1 diabetes pregnancy outcomes: impact of obesity and glycaemic control.

OBJECTIVE: To compare contemporary pregnancy outcomes in women with and without type 1 diabetes, and to examine the effects of obesity and glycaemic control on these outcomes. DESIGN AND SETTING: Historical cohort study in a specialist diabetes and maternity network in Victoria. PARTICIPANTS: All singleton births (at least 20 weeks' gestation), 2010-2013, were analysed: 107 pregnancies to women with type 1 diabetes and 27 075 pregnancies to women without diabetes. Women with type 2 diabetes or gestational diabetes were excluded. METHODS: Data were extracted from the Birthing Outcomes System database; associations between type 1 diabetes and pregnancy outcomes were analysed by multivariable regression. MAIN OUTCOME MEASURES: Mode of birth; maternal and neonatal outcomes. RESULTS: The mean body mass index was higher for women with type 1 diabetes than for women without diabetes (mean, 27.3 kg/m(2) [SD, 5.0] v 25.7 kg/m(2) [SD, 5.9]; P = 0.01); the median gestation period for their babies was shorter (median, 37.3 weeks [IQR, 34.6-38.1] v 39.4 weeks [IQR, 38.4-40.4]; P < 0.001) and they were more likely to be large for gestational age (LGA) (adjusted odds ratio [aOR], 7.9; 95% CI, 5.3-11.8). Women with type 1 diabetes were more likely to have had labour induced (aOR, 3.0; 95% CI, 2.0-4.5), a caesarean delivery (aOR, 4.6; 95% CI, 3.1-7.0), or a pre-term birth (aOR, 6.7; 95% CI, 4.5-10.0); their babies were more likely to have shoulder dystocia (aOR, 8.2; 95% CI, 3.6-18.7), hypoglycaemia (aOR, 10.3; 95% CI, 6.8-15.6), jaundice (aOR, 5.1; 95% CI, 3.3-7.7), respiratory distress (aOR, 2.5; 95% CI, 1.4-4.4) or to suffer perinatal death (aOR, 4.3; 95% CI, 1.9-9.9). In women with type 1 diabetes, greater obesity was associated with increased odds for an LGA baby or congenital malformation, and increased HbA1c levels were associated with pre-term birth and perinatal death. CONCLUSION: Women with type 1 diabetes, even when managed in a specialist setting, still experience adverse obstetric and neonatal outcomes. Poor glycaemic control is not wholly responsible for adverse outcomes, reinforcing the importance of other risk factors, such as obesity and weight gain.

Improving the provision of pregnancy care for Aboriginal and Torres Strait Islander women: a continuous quality improvement initiative.

BACKGROUND: Australian Aboriginal and Torres Strait Islander (Indigenous) women are at greater risk of adverse pregnancy outcomes than non-Indigenous women. Pregnancy care has a key role in identifying and addressing modifiable risk factors that contribute to adverse outcomes. We investigated whether participation in a continuous quality improvement (CQI) initiative was associated with increases in provision of recommended pregnancy care by primary health care centers (PHCs) in predominantly Indigenous communities, and whether provision of care was associated with organizational systems or characteristics. METHODS: Longitudinal analysis of 2220 pregnancy care records from 50 PHCs involved in up to four cycles of CQI in Australia between 2007 and 2012. Linear and logistic regression analyses investigated associations between documented provision of pregnancy care and each CQI cycle, and self-ratings of organizational systems. Main outcome measures included screening and counselling for lifestyle-related risk factors. RESULTS: Women attending PHCs after ≥1 CQI cycles were more likely to receive each pregnancy care measure than women attending before PHCs had completed one cycle e.g. screening for cigarette use: baseline = 73 % (reference), cycle one = 90 % [odds ratio (OR):3.0, 95 % confidence interval (CI):2.2-4.1], two = 91 % (OR:5.1, 95 % CI:3.3-7.8), three = 93 % (OR:6.3, 95 % CI:3.1-13), four = 95 % (OR:11, 95 % CI:4.3-29). Greater self-ratings of overall organizational systems were significantly associated with greater screening for alcohol use (ß = 6.8, 95 % CI:0.25-13), nutrition counselling (ß = 8.3, 95 % CI:3.1-13), and folate prescription (ß = 7.9, 95 % CI:2.6-13). CONCLUSION: Participation in a CQI initiative by PHCs in Indigenous communities is associated with greater provision of pregnancy care regarding lifestyle-related risk factors. More broadly, these findings support incorporation of CQI activities addressing systems level issues into primary care settings to improve the quality of pregnancy care.

Obesity, polycystic ovary syndrome and breastfeeding: an observational study.

INTRODUCTION: Polycystic ovary syndrome (PCOS) affects 9-21% of reproductive-age women. The relations between PCOS, body mass index (BMI) and breastfeeding are unclear. Our aim was to examine breastfeeding in women with and without PCOS and the relation with BMI. MATERIAL AND METHODS: This is a cross-sectional study set in the general community. Participants are women, aged 31-36 years, from the Australian Longitudinal Study on Women's Health (ALSWH), a large community-based study. Data was analyzed from the first child of respondents to Survey five (2009) reporting at least one live born child. Logistic regression analysis was used to examine factors associated with breastfeeding. The main outcome measures studied were breastfeeding initiation and duration and the main explanatory variables included self-reported PCOS and BMI. RESULTS: Of the 4898 women, 6.5% reported PCOS (95% confidence interval 5.8-7.2%). Median duration of breastfeeding was lower in women reporting PCOS (6 months, range 2-10 months) than in women not reporting PCOS (7 months, range 3-12 months) (p = 0.001). On multivariable regression analysis, there was no association between PCOS and breastfeeding outcomes. However, being overweight or obese was associated with not initiating breastfeeding and with breastfeeding for less than 6 months, after adjusting for confounders. CONCLUSIONS: High BMI is negatively associated with breastfeeding, whereas PCOS status per se does not appear to be related to breastfeeding initiation and duration, after adjusting for BMI.

Identifying health service barriers in the management of co-morbid diabetes and chronic kidney disease in primary care: a mixed-methods exploration.

BACKGROUND: Co-morbid diabetes and chronic kidney disease (CKD) are common in primary care but health care can be suboptimal. OBJECTIVE: In this multi-centre mixed-methods study, we investigated GPs' perspectives on health service barriers in managing diabetes and CKD as an initial step towards health care improvement. METHODS: Four focus groups were conducted among GPs in Australia's two largest cities. Transcripts underwent content analysis to inform development of a survey exploring health service barriers. This survey was then emailed/mailed to 840 GPs. Statistical analyses were performed using STATA v2.1. RESULTS: Responses were received from 13.7% of GPs (n = 115), mean (±SD) age 55.3 (10.1) years and mean duration of practice 26.6 (10.6). The majority (88.4%) reported wanting to manage diabetes and CKD in primary care with specialist assistance. However, 34.8% were unclear about the definition of CKD with 73.2% wanting more education. Access to specialist services was problematic with 39.3% and 28.2% reporting the process of referring patients to diabetes or CKD services, respectively, as hard. Coordination of care was also a problem with 35.6% unclear about each health care provider's role, 50.5% believing patients faced difficulties due to poor coordination across providers and 51.6% reporting duplication of tests. CONCLUSIONS: GPs expressed a clear interest in being the principal health care providers for patients with co-morbid diabetes and CKD. Supporting GPs and health care improvement focusing on overcoming reported barriers such as inadequate knowledge about CKD, access to specialist services and coordination of care may improve outcomes for people with co-morbid diabetes and CKD.

Continuous quality improvement and metabolic screening during pregnancy at primary health centres attended by Aboriginal and Torres Strait Islander women.

OBJECTIVE: To investigate associations between the provision of routine metabolic screening and follow-up in pregnancy and participation by primary health care centres in a large-scale continuous quality improvement (CQI) initiative. DESIGN: Longitudinal analysis of 2592 audited maternal health records. SETTING AND PARTICIPANTS: Seventy-six community-controlled or government-operated primary health care centres serving predominantly Aboriginal and Torres Strait Islander communities, in urban, regional or remote locations in five Australian states and territories. INTERVENTION: Up to four CQI cycles supported by the Audit and Best Practice for Chronic Disease Research Partnership. MAIN OUTCOMES MEASURES: Screening and follow-up for body mass index (BMI), blood pressure and diabetes in pregnancy. RESULTS: Overall, 87.9% of women attending the participating health centres were Aboriginal or Torres Strait Islander. Women attending a health centre after it had conducted one or more CQI cycles were more likely to receive BMI, blood pressure and diabetes screening. For example, the proportion of women receiving diabetes screening at baseline (before the first CQI cycle) was 56.1%; after cycle 1 it was 63.7% (odds ratio [OR], 1.3; 95% CI, 1.0-1.6), after cycle 2, 61.6% (OR, 1.2; 95% CI, 0.9-1.7), after cycle 3, 63.7% (OR, 1.7; 95% CI, 1.1-2.6), and after cycle 4, 75.5% (OR, 3.4; 95% CI, 1.9-5.9). Diabetes screening was associated with higher self-ratings of overall organisational systems (P = 0.03), self-management support (P = 0.04) and organisational influence and integration (P = 0.01). CONCLUSION: These findings support the value of CQI approaches that focus on systems-level issues in primary care to improve the provision of recommended pregnancy care at primary health care centres in predominantly Aboriginal and Torres Strait Islander communities.

Low vitamin D is associated with hypertension in paediatric obesity.

AIM: The aim of this paper was to investigate the relationship between circulating 25-hydroxyvitamin D (25(OH)D) and cardio-metabolic risk factors in a large cohort of obese youth attending tertiary paediatric obesity services. METHODS: We conducted a retrospective cross-sectional study. Data were retrospectively collected from all new consultations of children and adolescents attending obesity outpatient clinics between 2008 and 2011 at the two major paediatric hospitals in Melbourne, Australia. Information collected included demographics, anthropometry, blood pressure, pubertal staging, body composition and fasting serum levels of 25(OH)D, glucose, insulin, cholesterol, triglyceride, high-density lipoprotein, liver function, calcium and phosphate. RESULTS: 25(OH)D data were available in 229 patients (age 3-18 years; 116 men; mean (standard deviation) body mass index ( BMI) Z-score 2.5 (0.5) ). One hundred four (45%) participants were 25(OH)D deficient (<50 nmol/L). Lower serum 25(OH)D levels were associated with higher BMI Z-score (P-trend = 0.001), total fat mass (P-trend = 0.009), systolic (P-trend = 0.03) and diastolic blood pressures(P-trend = 0.009). In multivariable-adjusted regression analysis, 25(OH)D was significantly lower in those with elevated blood pressure after adjustment for BMI(P-trend = 0.004) or total fat mass (P-trend = 0.01). CONCLUSION: Overweight and obese youth attending specialist obesity services have a high prevalence of vitamin D deficiency. In this population, lower levels of vitamin D were seen in those with greater adiposity, and independent of this, in those who had higher blood pressure.

Continuous glucose monitoring versus self-monitoring of blood glucose in the management of cystic fibrosis related diabetes: A systematic review and meta-analysis.

BACKGROUND: Treatment of cystic fibrosis related diabetes (CFRD) can improve outcomes and use of continuous glucose monitoring (CGM) can positively impact glycemic control. We conducted a systematic review to assess current evidence on CGM compared to self-monitoring of blood glucose (SMBG) in the management of CFRD to determine its effect on glycemic, pulmonary, non-pulmonary and quality of life outcomes. METHODS: Using pre-defined selection criteria, we searched MEDLINE, Embase, CENTRAL, Evidence-Based Medicine Reviews, grey literature and six relevant journals for studies using CGM and/or SMBG in CFRD with greater than 6 weeks of follow-up and reported change in HbA1c. The primary outcome was weighted mean difference (WMD) in plasma HbA1c between CGM and SMBG groups. Secondary outcomes included exploring interrelationships between CGM metrics and effects on disease-specific pulmonary, non-pulmonary and quality of life outcomes. RESULTS: A total of 1671 references were retrieved, 862 studies screened and 124 full-texts assessed for eligibility. No studies directly compared CGM to SMBG. A meta-analysis of seventeen studies of 416 individuals (CGM = 138, SMBG = 278) found CGM group had 4.1 mmol/mol (95% CI -7.9 to -0.30, p = 0.034) lower HbA1c compared to SMBG group. Most studies demonstrated moderate-to-high risk of bias. Publication bias was also present. Heterogeneity was high and meta-regression identified duration of follow-up in SMBG group as main contributor. CONCLUSION: Our findings suggest use of CGM may be associated with improved glycemic control compared to SMBG in CFRD, however evidence of benefit on pulmonary, non-pulmonary and psychosocial outcomes are lacking.
