RESUMO
BACKGROUND: Fluoroscopic hysterosalpingography (HSG) with Lipiodol® is safe and has a therapeutic effect on fertility: transient in endometriosis-related infertility and sustained in unexplained infertility. Ultrasound is replacing fluoroscopy as the preferred imaging modality for HSG due to comfort and radiation safety (no ionising radiation). The safety of ultrasound-guided Lipiodol® HSG is uncertain. AIMS: Prospectively observe pregnancy and complication rates after ultrasound-guided Lipiodol® HSG. MATERIALS AND METHODS: A single-centre prospective study of women with unexplained infertility undergoing ultrasound-guided Lipiodol® uterine bathing and tubal flushing after tubal patency confirmed with ExEm® Foam HyFoSy (hysterosalpingo-foam-sonography). Pregnancy outcomes at six months and serum and urinary thyroid function at one, three and eight weeks were recorded. Pain scores were recorded during and immediately after HSG. Descriptive statistics are reported. RESULTS: Fifty-two participants were enrolled between July 2019 and April 2021, median age 33 years (range 21-45). Only 45 (87%, 45/52) completed the Lipiodol® HSG; 5/7 experienced intravasation during initial HyFoSy. Of 30 women at follow-up, 57% had biochemical (17/30, 95% CI 37%-75%), 53% clinical (16/30 95% CI 34%-72%) and 35% ongoing pregnancies (11/30, 95% CI 20%-56%). The rate of subclinical hypothyroidism (SCH) at two months was 41% (7/17). One intravasation event occurred during Lipiodol® HSG (2%, 1/45). Median pain score was 5/10 (range 0-9, interquartile range 2.5-7). No anaphylaxis, infection or oil embolism was observed. CONCLUSION: Outpatient ultrasound-guided Lipiodol® HSG was safe, with pregnancy rates comparable to previous studies of fluoroscopic guidance. Rates of intravasation and SCH were also similar, confirming the need to monitor thyroid function.

AIM: To assess participation with a structured transition programme for adolescents with diabetes. METHODS: Data from a regional cohort aged less than 16 years of age with type 1 (T1) and type 2 diabetes (T2D) in Auckland, New Zealand (2006-2016). Participation was defined as opting into a structured transition programme. RESULTS: Five hundrend and twelve adolescents who were to be transferred to adult care (476 type 1 (T1D) and 36 type 2 (T2D)), overall participation rate of 83%, 86% (408/476) with T1D compared to 47% (17/36) with T2D. Within the cohort of T1D, participation rates for Maori and Pacific were lower (74% and 77%, respectively) than New Zealand Europeans (88%, p = 0.020 and p = 0.039, respectively). Lower socio-economic status was associated with reduced participation (77%) compared to higher socio-economic status (90%, p = 0.002). Of the 476 T1D who participated, 408 (96%) subsequently attended at least one adult service clinic ("capture"). 42% attended an adult clinic within the planned 3 months, 87% at 6 months and retention in adult clinics over 5 years of follow-up was 78%. By contrast, the 68 young people with T1D who did not participate in the structured transition had a capture rate of 78% (p < 0.001) and retention of 63% (p = 0.036). CONCLUSIONS: In adolescents with diabetes, a formal transition from a paediatric service was associated with high rates of adult capture and subsequent retention in adult care over a 5-year follow-up period. Low socio-economic status, Maori or Pacific ethnicity and T2D were associated with reduced participation in the structured transition programme.

BACKGROUND: Vibration therapy (VT) has been increasingly studied in children with cerebral palsy (CP) over the last years, however, optimal therapeutic VT protocols are yet to be determined. The present study compared the effects of side-alternating VT protocols varying in frequency and treatment duration on the health of young children with mild-to-moderate CP. METHODS: Thirty-four participants aged 6.0 to 12.6 years with CP acted as their own controls and underwent two consecutive study periods: a 12-week lead-in (control) period prior to the intervention period of 20-week side-alternating VT (9 min/session, 4 days/week), with the frequency either 20 Hz or 25 Hz, determined by randomisation. Participants had 4 assessment visits: baseline, after the control period, after 12-week VT (12VT), and after further 8 weeks of VT (20VT). Assessments included 6-minute walk test (6MWT); dual-energy x-ray absorptiometry; gross motor function; muscle function testing on the Leonardo mechanography plate and by hand-held dynamometry, and a quality-of-life questionnaire (CP QOL). Analysis was carried out using linear mixed models based on repeated measures. RESULTS: Side-alternating VT was well-tolerated, with occasional mild itchiness reported. The median compliance level was 99%. VT led to improvements in 6MWT (+ 23 m; p = 0.007 after 20VT), gross motor function in standing skills (+ 0.8 points; p = 0.008 after 12VT; and + 1.3 points; p = 0.001 after 20VT) and in walking, running and jumping skills (+ 2.5 points; p < 0.0001 after 12VT; and + 3.7 points; p < 0.0001 after 20VT), spine bone mineral density z-score (+ 0.14; p = 0.015 after 20VT), velocity rise maximum of the chair rising test (+ 0.14 m/s; p = 0.021 after 20VT), force maximum of the single two-leg jump test (+ 0.30 N/kg; p = 0.0005 after 12VT; and + 0.46 N/kg; p = 0.022 after 20VT) and in the health module of CP QOL (+ 7 points; p = 0.0095 after 20VT). There were no observed differences between the two VT frequencies (i.e., 20 Hz vs 25 Hz) on study outcomes. CONCLUSIONS: The study confirms that side-alternating VT has positive effects on mobility, gross motor function, body composition, muscle function, and quality of life, independent of VT frequencies tested. Long-term, 20VT appears to be a more efficient treatment duration than a short-term, 12VT. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12618002026202 ; 18/12/2018.

AIM: Obesity as a major risk factor for childhood hypertension necessitates careful blood pressure (BP) monitoring of those affected. This study aimed to compare BP classification in a cohort of children affected by obesity using tables versus digital calculations in two sets of guidelines. METHODS: This study was a secondary analysis of data collected from a randomised clinical trial of a multidisciplinary life-style assessment and intervention program. Baseline data from 237 children with a body mass index >99th percentile or >91st percentile with weight-related comorbidities and available BP measurements were analysed. We assessed agreement between tables and algorithms in classification of elevated BP/pre-hypertension and hypertension based on the American Academy of Paediatrics (AAP) clinical practice guidelines (CPG) and the older Fourth Report using Cohen's weighted kappa. The prevalence of hypertensive diagnoses was also compared between the two guidelines. RESULTS: Agreement between BP tables and algorithmic calculation of percentiles was discordant, though improved in the AAP CPG compared to the Fourth Report (Cohen's kappa = 0.70 vs. 0.57, respectively). None (0%) were missed diagnoses, and 59 (24.9%) were false positives for the Fourth Report, and 0 (0%) were missed diagnoses, and 49 (20.9%) were false positives for the AAP CPG. Under the recent guidelines, there was an increase in prevalence of 6.0% (95% confidence interval (CI) 2.5-9.4%; P = 0.0001) for BP ≥90th percentile, and of 3.0% (95% CI 0.4-5.6%; p = 0.016) for hypertension (BP ≥ 95th percentile) in the cohort (18.0% and 6.8%, respectively, increased from 12.0% and 3.8%). CONCLUSIONS: Digital calculators over tables in clinical practice are recommended where possible to improve the accuracy of paediatric BP classification. Substantial rates of elevated BP/Hypertension were found in this cohort of children and adolescents with overweight and obesity.

Aims: To evaluate the feasibility and acceptability of vibration therapy (VT) in preschool children with cerebral palsy (CP) and obtain preliminary data on its potential effectiveness.Methods: Nine children aged 2.5-4.8 years (4 boys) with CP GMFCS levels I-III participated in a single-group feasibility study, undergoing a 12-week control period without intervention, followed by 12 weeks of home-based VT (four times/week, 9 min/day, frequency 20 Hz). We assessed adherence to VT protocol, adverse events, and family acceptability of VT. Clinical assessments included motor function (GMFM-66), body composition (DXA), mobility (10-meter walk/run test), and health-related quality of life (PedsQL).Results: VT was well tolerated and acceptable to families, with high adherence levels reported (mean = 93%). There were no observed between-period differences (ΔControl vs ΔVT) except for an improvement in the PedsQL "Movement & Balance" dimension with VT (p = 0.044). Nonetheless, changes after the VT but not the Control period were suggestive of potential treatment benefits for mobility, gross motor function, and body composition (lean mass and legs bone mineral density).Conclusion: Home-based VT is feasible and acceptable for preschool children with CP. Our preliminary data suggest potential health benefits from VT for these children, supporting larger randomized trials to assess its effectiveness properly.

OBJECTIVES: We examined whether caregivers of children/adolescents enroled in a randomised controlled trial (RCT) of a family-centred intervention indirectly achieved reductions in body mass index (BMI), and if these were associated with changes in their children's BMI. METHODS: RCT participants were New Zealand children/adolescents aged 4.8-16.8 years with BMI ≥ 98th percentile or >91st with weight-related comorbidities. Participants and accompanying caregivers were assessed at baseline, 12, and 24 months. RESULTS: Overall, caregivers' BMI was unchanged at 12 or 24 months. Among Maori participants, reductions in caregivers' BMI at 12 months were associated with reductions in their children's BMI SDS at 12 (r = 0.30; p = 0.038) and 24 months (r = 0.39; p = 0.009). Further, children identifying as Maori whose caregivers' BMI decreased at 12 months had greater BMI SDS reductions at 12 months [-0.30 (95% CI -0.49, -0.10); p = 0.004] and 24 months [-0.39 (95% CI -0.61, -0.16); p = 0.001] than children of caregivers with increased/unchanged BMI. CONCLUSIONS: This intervention programme for children/adolescents with obesity did not indirectly reduce caregiver weight status. However, reductions in caregivers' BMI were key to BMI SDS reductions among Maori participants. Given the intergenerational nature of obesity, our findings highlight the importance of culturally relevant, family-focused programmes to achieve clinically meaningful improvements in weight status across the family.

OBJECTIVE: To investigate whether protective psychological factors in young adults with type 1 diabetes are associated with more optimal self-care behaviors and HbA1c, and to explore possible mediators between protective psychological factors and HbA1c. RESEARCH DESIGN AND METHODS: This cross-sectional study examined the associations between protective psychological factors (optimism, positive efficacy expectancies, and self-compassion), maladaptive psychological factors (depression, anxiety, and stress), self-care behaviors, and HbA1c in 113 young adults (17-25 years) with type 1 diabetes in Auckland, New Zealand. Pearson's correlations, multiple linear regressions, and multiple mediation analyses were used to examine associations and mediators. RESULTS: Higher positive efficacy expectancies (beliefs about coping with difficulties) were associated with more optimal HbA1c (ß = -0.26, 95% CI: -1.99 to -0.45) and more optimal self-care behaviors (ß = 0.33, 95% CI: 0.28 to 0.92) in the adjusted models. Higher levels of self-compassion were associated with more optimal self-care behaviors (ß = 0.27, 95% CI: 0.09 to 0.43). Depression was associated with less optimal self-care behaviors (ß = -0.35, 95% CI: -1.33 to -0.43) and stress was associated with less optimal HbA1c (ß = 0.26, 95% CI: 0.27 to 1.21). Mediation results suggested that self-care behaviors mediated the relationship between all three of the protective psychological factors and more optimal HbA1c, and that lower stress also mediated the relationship between higher self-compassion and more optimal HbA1c. CONCLUSIONS: This study adds to the emerging literature that protective psychological factors may play an adaptive role in improving health outcomes in young adults with type 1 diabetes. Interventions targeting protective psychological factors present a promising approach to optimizing wellbeing and self-care in youth with type 1 diabetes.

OBJECTIVE: To evaluate the impact of a liquid chromatography-tandem mass spectrometry (LCMSMS) second-tier test on newborn screening for congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) in New Zealand. DESIGN: In a prospective study, a LCMSMS method to measure 17-hydroxyprogesterone (17OHP) was adapted to measure four additional steroids. Steroid concentrations were collected on all second-tier CAH screening tests while protocols remained unchanged. Steroid ratio parameters with recommended or published screening cuts-offs were evaluated for their impact on newborn screening performance. MEASUREMENTS: Precision, accuracy, linearity and recovery of the second-tier LCMSMS method were evaluated. Second-tier specimens were divided in 3 groups; newborn screening bloodspots from neonates with confirmed CAH (n = 7) and 2 groups specimens from neonates with a birthweight (BW) ≤1500 g (n = 795) and with a BW > 1500 g (n = 806) with a negative newborn screening test. Six protocols using four steroid ratio parameters were evaluated. The sensitivity, specificity, false positive rate and positive predictive value of screening was calculated for each protocol. RESULTS: The LCMSMS method was sufficiently accurate and precise to be used as a second-tier test for CAH. Screening sensitivity remained at 100% for each protocol apart from (17OHP + androstenedione)/cortisol when the highest cut-off of 3.75 was applied. The false positive rate was significantly improved when (17OHP + androstenedione)/cortisol and (17OHP + 21-deoxycortisol)/cortisol were evaluated with cut-offs of 2.5 and 1.5 respectively (P < .01) and both with a positive predictive value of 64%. CONCLUSIONS: A second-tier LCMSMS newborn screening test for CAH offers significant improvements to screening specificity without any other changes to screening protocols.

Recent interest in the use of oil-soluble contrast media (OSCM) for hysterosalpingography (HSG) and other tubal flushing procedures is largely the result of publication of the large, multicentre, randomized controlled H2Oil trial in the New England Journal of Medicine in 2017, addressing the long-held suspicion that pregnancy rates following HSG with OSCM are higher than if a water-soluble contrast media (WSCM) is used. However, the findings of this trial have been compromised by the WSCM selected for comparison with OSCM. The chosen WSCM belongs to a superceded class of ionic media, with an iodine concentration, osmolality and viscosity all lying at the extreme end of the range for water-soluble radiographic contrast. The requirement for safe, cheap, versatile WSCM for intravascular use during computerized tomography, angiography and interventional procedures has resulted in considerable refinement of WSCM, with current widespread use of non-ionic, low osmolality or iso-osmolar WSCM in radiology, including for HSG. However, the use of the earlier ionic, high osmolality agents such as that selected for the H2Oil trial persists for HSG in some centres, despite potential adverse effects on the endometrium and fallopian tubal epithelium compared with more modern, less toxic WSCM. Knowledge of the variety of physical and chemical characteristics of the available WSCM is essential for interpretation of the current literature and establishing the most effective and safe water-soluble agent to use for HSG. Design of future clinical trials to establish the potential superiority of OSCM over WSCM for fertility enhancement must include the use of the readily available, inexpensive modern WSCM. While the fertility rates following OSCM HSG have been shown to be high in women with idiopathic infertility, more robust trials are required before the widespread use of OSCM for HSG or other modalities such as ultrasound and laparoscopy should be adopted.

Iodine is a vital micronutrient and its importance in thyroid function is well established. However, abnormalities in iodine intake may also have other effects. In particular, iodine is taken up avidly by the ovary and endometrium. Iodine deficiency is associated with reduced fertility. The use of high iodine concentration contrast media has recently been shown to improve conception rates in couples with unexplained infertility (UI). We hypothesize that this improvement could be related to the iodine excess and mechanisms independent of its action on thyroid. In this article, the metabolism of iodine and its potential role in fertility will be discussed, including the impact of both iodine deficiency and excess states and the importance of iodine in normal fetal development. This will include insights from animal studies on the effect of iodine in the uterine and ovarian structural environment, hormonal milieu and immunological factors affecting implantation. We speculate that iodine may well have a role as a potential therapy for UI.

BACKGROUND: Adolescents with type 1 diabetes (T1D) experience higher rates of psychological disorders compared with their healthy peers. As poor psychological health has been associated with suboptimal glycaemic control and more frequent complications, there is an urgent need to develop more 'clinically usable' interventions. Digital mental health interventions offer unique advantages compared with in-person interventions; however, what adolescents with T1D want in terms of content and functionality is poorly understood. Accordingly, the current study conducted focus groups to examine the views of adolescents with T1D regarding digital mental health interventions. METHODS: Four focus groups were conducted, including 16 adolescents with T1D, ranging from 13 to 17 years in age (69% female). Transcripts were analysed using directed content analysis to examine (1) 'what adolescents dislike about existing digital mental health interventions?' and (2) 'what adolescents want in future digital mental health interventions?'. RESULTS: Findings provide a preliminary understanding of what adolescents dislike and also the type of content and functional features, which may be important to include in digital mental health programs for this population, such as a peer support feature (reported by 16 of 16), emotion and diabetes check-in feature (11 of 16) and diabetes-relevant content (12 of 16). CONCLUSIONS: Early data suggest that digital mental health interventions should include a significant peer support element, diabetes-relevant content and examples, and check-in on their mental health and diabetes self-management regularly, while avoiding fixed responses or modules and non-age-appropriate content. Based on these findings, a digital intervention is currently being developed.

OBJECTIVE: To determine the incidence of new onset type 1 diabetes in children aged 0-14 years from 1977 to 2019 in Auckland, New Zealand. RESEARCH DESIGN AND METHODS: A cohort study of children with type 1 diabetes aged 0-14 years (n = 1688; 50.4% male) managed by the regional diabetes service between 1977 and 2019. Incidence rates were estimated using census data. RESULTS: The incidence of type 1 diabetes increased by 2.9%/year from 1977 to 2006 (95% confidence interval [CI] 2.13% - 3.48%). Although there was no significant change from 2006 to 2019 (-0.3%/year, 95% CI -1.62% - 1.08%), there was a dramatic fall from 1976 to 2018 in the proportion of New Zealand Europeans, from 69.9 to 33.9%. New Zealand Europeans had the highest incidence (23.3/100,000, 95% CI 20.6-26.1) compared to Maori (8.3/100,000, 95% CI 6.3-10.2), Pasifika (8.6/100,000, 95% CI 6.9-10.4) and other (6.4/100,000, 95% CI 4.7-8.0). All groups showed an overall increase in incidence over time, Maori 4.4%/year, Pasifika 3.7%, compared to New Zealand European 2.7%, and other 2.1%. Incidence increased consistently in 5-9 and 10-14 year olds (2.0% and 2.2%/year, respectively). By contrast, whereas 0-4 year olds showed an increase of 4.6%/year from 1977 to 2003 (p < 0.01), there was no change from 2003 to 2019 (p = 0.2). CONCLUSION: There has been a plateau in the incidence of type 1 diabetes in children 0-4 years of age in the Auckland region since 2003, but not older children. The apparent plateau in the overall incidence of new onset type 1 diabetes in children 0-14 years since 2006 was mediated by substantial changes in the ethnic makeup of the Auckland region.

BACKGROUND: The first report of children born very preterm (<32 weeks of gestation) having insulin resistance was made 16 years ago. However, neonatal care has improved since. Thus, we aimed to assess whether children born very preterm still have lower insulin sensitivity than term controls. METHODS: Participants were prepubertal children aged 5 to 11 years born very preterm (<32 weeks of gestation; n = 51; 61% boys) or at term (37-41 weeks; n = 50; 62% boys). Frequently sampled intravenous glucose tolerance tests were performed, and insulin sensitivity was calculated using Bergman's minimal model. Additional clinical assessments included anthropometry, body composition using whole-body dual-energy X-ray absorptiometry scans, clinic blood pressure, and 24-hour ambulatory blood pressure monitoring. RESULTS: Children born very preterm were 0.69 standard deviation score (SDS) lighter (P < .001), 0.53 SDS shorter (P = .003), and had body mass index 0.57 SDS lower (P = .003) than children born at term. Notably, children born very preterm had insulin sensitivity that was 25% lower than term controls (9.4 vs 12.6 × 10-4 minutes-1 ·[mU/L]; P = .001). Other parameters of glucose metabolism, including fasting insulin levels, were similar in the two groups. The awake systolic blood pressure (from 24-hour monitoring) tended to be 3.1 mm Hg higher on average in children born very preterm (P = .054), while the clinic systolic blood pressure was 5.4 mm Hg higher (P = .002). CONCLUSIONS: Lower insulin sensitivity remains a feature of children born very preterm, despite improvements in neonatal intensive care. As reported in our original study, our findings suggest the defect in insulin action in prepubertal children born very pretermis primarily peripheral and not hepatic.

OBJECTIVE: The objective of the current study was to identify challenges of making and sustaining healthy lifestyle changes for families with children/adolescents affected by obesity, who were referred to a multicomponent healthy lifestyle assessment and intervention programme in Aotearoa/New Zealand (NZ). DESIGN: Secondary qualitative analysis of semi-structured interviews. SETTING: Taranaki region of Aotearoa/NZ. PARTICIPANTS: Thirty-eight interviews with parents/caregivers (n 42) of children/adolescents who had previously been referred to a family-focused multidisciplinary programme for childhood obesity intervention, who identified challenges of making healthy lifestyle changes. Participants had varying levels of engagement, including those who declined contact after their referral. RESULTS: Participant-identified challenges included financial cost, impact of the food environment, time pressures, stress, maintaining consistency across households, independence in adolescence, concern for mental health and frustration when not seeing changes in weight status. CONCLUSIONS: Participants recognised a range of factors that contributed towards their ability to make and sustain change, including factors at the wider socio-environmental level beyond their immediate control. Even with the support of a multidisciplinary healthy lifestyle programme, participants found it difficult to make sustained changes within an obesogenic environment. Healthy lifestyle intervention programmes and families' abilities to make and sustain changes require alignment of prevention efforts, focusing on policy changes to improve the food environment and eliminate structural inequities.

In a recent issue of the BMC Public Health journal, Littlewood et al. described the results of a systematic review of interventions to prevent or treat childhood obesity in Maori or Pacific Island peoples. They found that studies to date have had limited impact on improving health outcomes for Maori and Pacific Island peoples, and suggest this may be due to a lack of co-design principles in the conception of the various studies. Ensuring that interventions are appropriate for groups most affected by obesity is critical; however, some inaccuracies should be noted in the explanation of these findings. There is a risk with systematic reviews that the context of intervention trials is lost without acknowledging the associated body of literature for programmes that refer to the ongoing commitment to communities and groups most affected by obesity.

AIM: It is important that intervention programmes are accessible and acceptable for groups most affected by excess weight. This study aimed to understand the barriers to and facilitators of engagement for Maori in a community-based, assessment-and-intervention healthy lifestyle programme (Whanau Pakari). METHODS: Sixty-four in-depth, home-based interviews were conducted with past service users. Half of these were with families with Maori children and half with non-Maori families. The interviews were thematically analysed with peer debriefing for validity. RESULTS: Maori families experienced barriers due to racism throughout the health system and society, which then affected their ability to engage with the programme. Key barriers included the institutionalised racism evident through substantial structural barriers and socio-economic challenges, the experience of interpersonal racism and its cumulative impact with weight stigma, and internalised racism and beliefs of biological determinism. Responses to these barriers were distrust of health services, followed by renewed engagement or complete disengagement. Participants identified culturally appropriate care as that which was compassionate, respectful, and focused on relationship building. CONCLUSIONS: While Whanau Pakari is considered appropriate due to the approach of the delivery team, this is insufficient to retain some Maori families who face increased socio-economic and structural barriers. Past instances of weight stigma and racism have enduring effects when re-engaging with future health services, and inequities are likely to persist until these issues are addressed within the health system and wider society.

AIM: Expert recommendations for child/adolescent obesity include extensive investigation for weight-related comorbidities, based on body mass index (BMI) percentile cut-offs. This study aimed to estimate the cost of initial investigations for weight-related comorbidities in children/adolescents with obesity, according to international expert guidelines. METHODS: The annual mean cost of investigations for weight-related comorbidities in children/adolescents was calculated from a health-funder perspective using 2019 cost data obtained from three New Zealand District Health Boards. Prevalence data for child/adolescent obesity (aged 2-14 years) were obtained from the New Zealand Health Survey (2017/2018), and prevalence of weight-related comorbidities requiring further investigation were obtained from a previous New Zealand study of a cohort of children with obesity. RESULTS: The cost of initial laboratory screening for weight-related comorbidities per child was NZD 28.36. Based on national prevalence data from 2018/2019 for children with BMI greater than the 98th percentile (obesity cut-off), the total annual cost for initial laboratory screening for weight-related comorbidities in children/adolescents aged 2-14 years with obesity was estimated at NZD 2,665,840. The cost of further investigation in the presence of risk factors was estimated at NZD 2,972,934. CONCLUSIONS: Investigating weight-related comorbidities in New Zealand according to international expert guidelines is resource-intensive. Ways to further determine who warrants investigation with an individualised approach are required.

We describe the approach of an Indigenous-non-Indigenous research partnership in the context of a qualitative study which aimed to understand barriers and facilitators to engagement in a community-based healthy lifestyles program in Aotearoa/New Zealand. Informed by Kaupapa Maori research principles and by "Community-Up" research values, this collaborative approach between the mixed Maori-non-Maori research team effectively engaged with Maori and non-Maori families for in-depth interviews on participant experience, including with non-service users. "Community-Up" research principles allowed for a respectful process which upheld the mana (status, dignity) of the interview participants and the research team. Challenges included maintaining flexibility in our conceptions of ethnicity to reflect the complexity of modern family life in Aotearoa/New Zealand. We were committed to ongoing communication, awareness, and attention to the relationships that formed the basis of our research partnership, which allowed effective navigation of challenges and was critical to the study's success.

AIMS: To evaluate the effects of side-alternating vibration therapy on physical function and body composition in adolescents with Down syndrome. METHODS: Fourteen adolescents (8 males) with Down syndrome (mean ± SD age: 15.5 ± 2.3 years) performed vibration treatment nine minutes daily, four times per week, for 20 weeks on a Galileo vibration platform. Data were collected at baseline and after 20 weeks of intervention. Assessments included six-minute walk test, muscle function (force plate), whole-body dual-energy X-ray absorptiometry and peripheral quantitative computed tomography of the non-dominant tibia. RESULTS: After 20 weeks, participants increased their distance walked in the six-minute walk test (p = 0.009), 2-leg single jump efficiency (p = 0.024) and jump velocity (p = 0.046). Participants also increased their power (p = 0.034) and reduced the time taken during the chair rise test (p < 0.001). At the total body level, increases were seen in bone mineral density (p = 0.004), bone mineral content (p = 0.043), fat free mass (p = 0.013) and lean mass (p = 0.021). CONCLUSION: Side-alternating vibration therapy was associated with increases in physical function and muscle mass with no effects on bone health in adolescents with Down syndrome. CLINICAL TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trial Registry (ACTRN12615000092594) - registered on 4th February 2015.

BACKGROUND: Previous studies reported impaired glucose homeostasis among preterm survivors, but consisted almost exclusively of Caucasians. It is unknown whether Asians born preterm display similar impairments. AIM: To assess glucose homeostasis and other cardiometabolic outcomes among young adults born preterm in Thailand. METHODS: Participants were 575 young adult offspring of mothers from the Chiang Mai Low Birth Weight Study, born in 1989 to 1990 and followed up in 2010: 54.1% females, median age 20.6 years, including 33 individuals (5.7%) born preterm. After an overnight fast, participants underwent clinical assessments, including blood sampling (glucose, insulin, and lipid profile). Insulin sensitivity was assessed using HOMA-IR and insulin secretion estimated using HOMA-ß. RESULTS: In unadjusted analyses, young Thai adults born preterm were 3.2 cm shorter (P = .037), 6 kg lighter (P = .016), and had HOMA-ß 34% higher (P = .026) than those born at term. Adjusted analyses accounting for important confounders showed marked impairments in glucose homeostasis among preterm survivors: fasting insulin levels were 32% greater (P = .011), with HOMA-IR and HOMA-ß that were 31% (P = .020) and 43% higher (P = .005), respectively, compared to peers born at term. There were no other contrasting observations between groups, with anthropometric differences disappearing after adjustment for confounders. DISCUSSION: Young adults in Thailand born preterm were more insulin resistant than peers born at term. The observed impairments in glucose metabolism among young Thai adults born preterm corroborate findings reported mostly on Caucasians. The challenge for general practitioners and public health professionals is to encourage those born preterm to make healthier lifestyle choices early on.
