Objective: Maternal obesity, usually associated with the adverse birth outcomes, has been a serious public health concern. Studies examining its effect on the physical and cognitive development of children have only recently emerged and the findings are inconsistent. This review aimed to systematically examine the role of maternal obesity on children’s physical and cognitive development using the available evidence. Methods: The CINAHL, EMBASE, PSYCINFO, PUBMED and SCOPUS databases were searched. Studies addressing children’s (⩽12 years) physical and cognitive development as outcome and maternal pre-pregnancy body mass index as an exposure were included. Data were extracted and evaluated for quality by two independent reviewers. Results: A total of 17 articles were eligible for this systematic review; 10 of them were birth cohorts from the USA. Nine of the 14 studies supported an adverse association between maternal pre-pregnancy obesity and childhood cognitive development. A few studies also demonstrated a negative association between the maternal obesity and gross motor function in children (5 of 10), but not with fine motor function (none out of five studies). Whether the observed negative association between the maternal obesity and children’s cognitive and gross motor abilities is casual or due to residual confounding effects is unclear. The current evidence is based on a limited number of studies with heterogeneous measurement scales and obesity definition. Conclusions: From the available evidence, it seems that exposure to maternal pre-pregnancy obesity in the intrauterine environment has a detrimental effect on children’s cognitive development. However, evidence of the association between the maternal obesity and physical development of children is too scarce to offer a conclusion. More research work is required to delineate the intrauterine effect of the maternal obesity from the residual confounding effects.

There is limited evidence on the association between maternal preconception body mass index (BMI) trajectories and pregnancy complications and child development. This study examined the relationships of maternal BMI trajectories, diabetes and hypertensive disorders during pregnancy and offspring’s childhood physical and cognitive development. Data were from the Australian Longitudinal Study on Women’s Health and the Mothers and their Children’s Health study (n=771). Women’s preconception BMI trajectories were identified using group-based trajectory modelling. Children’s physical and cognitive development (up to the average age of 5 years) were obtained from the Ages and Stages Questionnaire (suspected gross motor delay) and the Australian Early Development Census (AEDC). Generalized estimating equation models, adjusted for maternal sociodemographic and lifestyle factors, were used for analyses. Three distinct BMI trajectories were identified (normative, chronically overweight and chronically obese). Children born to chronically obese women were more likely to be classified as developmentally vulnerable/at-risk on AEDC domains; gross and fine motor skills [risk ratio (RR)=1.64, 95% confidence interval (CI): 1.04, 2.61] and communication skills and general knowledge (RR=1.71, 95% CI: 1.09, 2.68). They also had an elevated risk of suspected gross motor delay (RR=2.62, 95% CI: 1.26, 5.44) compared with children born to women with a normative BMI trajectory. Maternal diabetes or hypertensive disorders during pregnancy were not associated with child outcomes. Maternal preconception BMI trajectories were associated with poorer childhood development. This study finding underscores the importance of excessive weight gain prevention throughout the reproductive stage of life.

While birthweight of offspring is associated with pre-pregnancy body mass index (BMI) and later risk of obesity, its mediating effect between the association of maternal pre-pregnancy BMI and offspring’s childhood anthropometrics has rarely been investigated. This study aimed to examine whether offspring birthweight is a mediator in the association between pre-pregnancy BMI and offspring’s childhood anthropometrics. The study included 1,618 mother–child pairs from the Australian Longitudinal Study on Women’s Health and Mothers and their Children’s Health Study. Children’s anthropometrics [mean age 8.6 (s.d. =3.0) years] were calculated from the mothers’ self-reported child weight and height measures. G-computation was used to estimate the natural direct and indirect (via birthweight) effects of pre-pregnancy BMI. In the fully adjusted model for maternal sociodemographic and lifestyle factors, the natural direct effects of pre-pregnancy obesity on child BMI-for-age, height-for-age, weight-for-age and weight-for-height outcomes were, β (95% confidence interval, CI), 0.75 (0.55, 0.95), 0.13 (−0.07, 0.32), 0.62 (0.44, 0.80) and 0.57 (0.24, 0.90), respectively. The corresponding natural indirect effects were 0.04 (−0.04, 0.12), −0.01 (−0.09, 0.07), −0.01 (−0.08, 0.07) and 0.09 (−0.05, 0.23). Similar results were observed for pre-pregnancy overweight and pre-pregnancy BMI as a continuous scale. Most of the effect of pre-pregnancy obesity on childhood weight-related anthropometric outcomes appears to be via a direct effect, not mediated through offspring’s birthweight.

OBJECTIVE. Capener splinting is a common treatment for extension deficit of the proximal interphalangeal (PIP) joint. This study compared the effect of daily splint total end range time (TERT) of 6–12 hr versus 12–16 hr. METHOD. Twenty-two participants with extension deficits of the PIP joint were randomly allocated to a daily TERT of 6–12 hr or 12–16 hr. Progress after 8 wk of splinting was evaluated. RESULTS. No significant difference was found in change in extension range of motion (ROM) between groups (active ROM, F[4, 17] = 2.19, p = .13; passive ROM, F[4, 17] = 0.95, p = .46; torque ROM, F[4, 17] = 1.49, p = .26). Considerable crossover between groups resulted in a similar average daily TERT (9.5 hr for the 6–12 hr group vs. 11.5 hr for the 12–16 hr group). CONCLUSION. Further research with a larger sample is needed to determine whether longer daily TERT is beneficial. Our results suggest, however, that most patients find it difficult to wear splints >12 hr/day.

Maternal obesity, usually associated with the adverse birth outcomes, has been a serious public health concern. Studies examining its effect on the physical and cognitive development of children have only recently emerged and the findings are inconsistent. This review aimed to systematically examine the role of maternal obesity on children's physical and cognitive development using the available evidence. The CINAHL, EMBASE, PSYCINFO, PUBMED and SCOPUS databases were searched. Studies addressing children's ([[less-than or slanted equal to]12 years) physical and cognitive development as outcome and maternal pre-pregnancy body mass index as an exposure were included. Data were extracted and evaluated for quality by two independent reviewers. A total of 17 articles were eligible for this systematic review; 10 of them were birth cohorts from the USA. Nine of the 14 studies supported an adverse association between maternal pre-pregnancy obesity and childhood cognitive development.

Objective: To determine item, subscale and total score agreement on the Frenchay Activities Index (FAI) between stroke patients and proxies six months after discharge from rehabilitation. Design: Prospective study design. Setting/subjects: Fifty patient–proxy pairs, interviewed separately, in the patient's residence. Main outcome measures: Modified FAI using 13 items. Individual FAI items, subscales and total score agreement as measured by weighted kappa and intraclass correlation coefficients (ICC). Results: Excellent agreement was found for the total FAI (ICC 0.87, 95% confidence interval (CI) 0.78–0.93), and domestic (ICC 0.85, 95% CI 0.73–0.91) and outdoor (ICC 0.87, 95% CI 0.78–0.95) subscales, with moderate agreement found for the work/leisure subscale (ICC 0.63, 95% CI 0.34–0.78). For the individual FAI items, good, moderate, fair and poor agreement was found for five, three, four and one item, respectively. The best agreement was for objective items of preparing meals, washing-up, washing clothes, shopping and driving. The poorest agreement was for participation in hobbies, social outings and heavy housework. Scoring biases associated with patient or proxy demographic characteristics were found. Female proxies, and those who were spouses, scored patients lower on domestic activities; male patients, and those who were younger, scored themselves higher on outdoor activities and higher patient FIM scores were positively correlated with higher FAI scores. Conclusions: While total and subscale agreement on the FAI was high, individual item agreement varied. Proxy scores should be used with caution due to bias.

SummaryWe identified demographic, health and lifestyle factors associated with falls in adults aged 50–64 years from Australia, The Netherlands, Great Britain and Ireland. Nearly all factors were associated with falls, but there were differences between countries and between men and women. Existing falls prevention programs may also benefit middle-aged adults.IntroductionBetween ages 40–44 and 60–64 years, the annual prevalence of falls triples suggesting that middle age may be a critical life stage for preventive interventions. We aimed to identify demographic, health and lifestyle factors associated with falls in adults aged 50–64 years.MethodsHarmonised data were used from four population-based cohort studies based in Australia (Australian Longitudinal Study on Women’s Health, n = 10,641, 51–58 years in 2004), Ireland (The Irish Longitudinal Study on Ageing, n = 4663, 40–64 years in 2010), the Netherlands (Longitudinal Ageing Study Amsterdam, n = 862, 55–64 years in 2012–13) and Great Britain (MRC National Survey of Health and Development, n = 2987, 53 years in 1999). Cross-sectional and prospective associations of 42 potential risk factors with self-reported falls in the past year were examined separately by cohort and gender using logistic regression. In the absence of differences between cohorts, estimates were pooled using meta-analysis.ResultsIn cross-sectional models, nearly all risk factors were associated with fall risk in at least one cohort. Poor mobility (pooled OR = 1.71, CI = 1.34–2.07) and urinary incontinence (OR range = 1.53–2.09) were consistently associated with falls in all cohorts. Findings from prospective models were consistent. Statistically significant interactions with cohort and sex were found for some of the risk factors.ConclusionRisk factors known to be associated with falls in older adults were also associated with falls in middle age. Compared with findings from previous studies of older adults, there is a suggestion that specific risk factors, for example musculoskeletal conditions, may be more important in middle age. These findings suggest that available preventive interventions for falls in older adults may also benefit middle-aged adults, but tailoring by age, sex and country is required.

Objectives Faecal serine proteases (FSPs) may play a role in irritable bowel syndrome with diarrhoea (IBS-D), but their origin is unclear. We aimed to structurally characterise them and define the impact of colonic cleansing and transit time. Design Faecal samples were obtained from 30 healthy volunteers (HV) and 79 patients with IBS-D participating in a trial of ondansetron versus placebo. Colonic transit was measured using radio-opaque markers. Samples were also obtained from 24 HV before and after colonic cleansing with the osmotic laxative MoviPrep. FSPs were purified from faecal extracts using benzamidine-Sepharose affinity chromatography. SDS-PAGE profiled components were identified using trypsinolysis and tandem mass spectrometry. Functional protease activity in faecal extracts was measured using a colorimetric assay based on the proteolysis of azo-casein. Results Protein analysis identified the most abundant FSPs as being of human origin and probably derived from pancreatic juice. Functional assays showed increased faecal protease (FP) and amylase in patients with IBS-D compared with HV. Those with higher amylase had significantly higher FP and greater anxiety. FP activity correlated negatively with whole gut transit in patients with IBS-D (Spearman r=−0.32, p=0.005) and HV (r=−0.55, p=0.014). Colon cleansing caused a significant rise in FP activity in HV from a baseline of median (IQR) 253 (140–426) to 1031 (435–2296), levels similar to those seen in patients with IBS-D. FSP activity correlated positively with days/week with urgency. Conclusions The most abundant FSPs are of human origin. Rapid transit through the colon and/or decreased (possibly bacterial) proteolytic degradation increases their faecal concentration and could contribute to visceral hypersensitivity in patients with IBS-D.

Corticosteroids have been used to treat head injuries for more than 30 years. In 1997, findings of a systematic review suggested that these drugs reduce risk of death by 1-2%. The CRASH trial--a multicentre international collaboration--aimed to confirm or refute such an effect by recruiting 20000 patients. In May, 2004, the data monitoring committee disclosed the unmasked results to the steering committee, which stopped recruitment. 10008 adults with head injury and a Glasgow coma score (GCS) of 14 or less within 8 h of injury were randomly allocated 48 h infusion of corticosteroids (methylprednisolone) or placebo. Primary outcomes were death within 2 weeks of injury and death or disability at 6 months. Prespecified subgroup analyses were based on injury severity (GCS) at randomisation and on time from injury to randomisation. Analysis was by intention to treat. Effects on outcomes within 2 weeks of randomisation are presented in this report. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN74459797. Compared with placebo, the risk of death from all causes within 2 weeks was higher in the group allocated corticosteroids (1052 [21.1%] vs 893 [17.9%] deaths; relative risk 1.18 [95% CI 1.09-1.27]; p=0.0001). The relative increase in deaths due to corticosteroids did not differ by injury severity (p=0.22) or time since injury (p=0.05). Our results show there is no reduction in mortality with methylprednisolone in the 2 weeks after head injury. The cause of the rise in risk of death within 2 weeks is unclear.

Descriptive design with a prospective cohort. Little is known about the long-term relationship between the duration of treatment using dynamic orthoses (splints), and contracture resolution in the stiff proximal interphalangeal (PIP) joint. To examine the long-term relationship between weeks of treatment using dynamic orthoses and contracture resolution, in both flexion and extension deficits of the PIP joint. Forty-one participants were treated with a dynamic orthotic device (splint) for either a flexion or extension deficit of the PIP joint ( n = 48 joints). The relationship between contracture resolution and weeks of treatment was examined controlling for baseline range of motion (ROM), weekly total end range time, pretreatment joint stiffness, time since injury, and diagnosis. Outcome was measured via change in torque and active ROM. Outcome with orthotic use was significantly associated with the weeks of treatment (p < 0.001). ROM increased in a linear fashion although faster progress was observed when treatment was aimed at improving flexion rather than extension. Flexion deficits appeared to maximize gains with orthotic treatment after 12 weeks. However, extension deficits continued to demonstrate slow and continuous improvement beyond the 17 weeks of recorded data. Less treatment duration (in weeks) was needed to restore flexion than extension. The duration of orthotic use (weeks of treatment) is significantly associated with the extent of contracture resolution. Slower recovery of ROM and a longer duration of orthotic use may be expected when the treatment goal is to improve extension rather than flexion. 2b.
