Objective: To evaluate the construct validity of the Activity Inventory of the Chedoke-McMaster Stroke Assessment and the Clinical Outcome Variables Scale (COVS), 2 measures of functional mobility. Design: A retrospective longitudinal study of 24 inpatients (mean age 83 years (standard deviation 7)) on a geriatric rehabilitation unit.Participants: The primary reasons for admission were de- conditioning (n=9) and hip fracture (n=7). Method: We tested hypotheses that Activity Inventory and COVS scores at admission and discharge, and change scores during hospital stay would correlate. Longitudinal construct validity was also estimated using effect size and standardized response mean. Results: Correlations between scores on each measure ranged from r=0.59-0.93 across subscales and total scales (p<0.01). The effect size of the Activity Inventory and the COVS was 1.53 and 1.43, respectively. The standardized response mean of the Activity Inventory and the COVS was 1.83 and 2.30, respectively. Conclusion: Although findings support the validity of both measures, the COVS appears more efficient and sensitive than the Activity Inventory to change in this population. A larger study is needed to confirm these findings. Journal Compilation © 2010 Foundation of Rehabilitation Information.

AIM: To investigate whether the decline in sperm concentration in New Zealand sperm donors observed from 1987 to 2007 continued in the period 2008–2014. METHOD: A retrospective study from 2008 to 2014. The first semen sample of 285 men presenting as sperm donors in Auckland and Wellington was analysed for sperm concentration, seminal fluid volume and the percentage of motile sperm. These results were compared to results from 1987 to 2007 from the same clinics. RESULTS: The decline in semen volume and sperm concentration observed between 1987 and 2007 did not continue in 2008–2014. Sperm concentration decreased from 1987 until some time between 1997 and 2001, and has remained stable at an average of 62x106/ml between 2001 and 2014. Sperm motility declined significantly (8%) in the period 2008–2014, but there was no significant change over the total period studied, between 1987 and 2014. CONCLUSION: After a decline between 1987 and sometime during 1997–2001, the sperm concentration in men presenting as donors remained unchanged between 2002 and 2014, suggesting semen quality has not changed in New Zealand men over the last decade. © NZMA.

Background While evidence suggests sleep problems are common in young children and linked to behavioural problems, studies of toddlers are rare. This community-based cross-sectional study examined associations between sleep problems and daytime behaviour among 58 children aged 1 to 3 years who attended daycare centres. Methods Mothers and daycare providers completed four and three questionnaires, respectively, about children's sleep patterns and behaviour. Two hypotheses were tested: (1) children with higher sleep problem scores would have more behavioural problems by parental and daycare provider report; (2) problematic napping behaviours would be associated with night sleep problems. Results Mothers' reports of sleep problems were positively associated with children's behavioural problems at home and daycare providers' reports of nap problems were positively correlated with children's behavioural problems at daycare. Daycare providers' reports of children's behavioural problems at daycare were associated with maternal reports of behavioural problems. Older children in the sleep problem group had maternal reports of more behavioural problems. Daycare providers reported that children with sleep problems were less happy at daycare. Children who were happier following naps had less reported night settling difficulties. Children with difficulty settling for naps at daycare had maternal reports of more behavioural problems. Conclusions Napping in daycare settings is an important component of toddlers' sleep. Crossover effects between children's sleep and behaviour at daycare and home indicate similarities in mothers' and daycare providers' perceptions. Findings suggest parent and daycare provider interactions include discussions about sleep problems and settling at home and in daycares. Parents and daycare providers would benefit from education about relationships between sleep and behavioural problems. © 2011 Blackwell Publishing Ltd.

Wire Bond Shear (WBS) test is a method for evaluating the strength of a ball bond, to complement wire pull test. In foundry, wafer-level (WLR) WBS provides a quick way to demonstrate the integrity of metal bond pad, backend scheme as well as bond or via design. This is a big challenge for WLR WBS outsourcing as many of the factors affecting shear strength lying on the wire bonding parameters and shear test setup. This paper presents the outsourcing experiences of WBS tests and good shear strength was achieved from the outsource laboratory. © 2011 IEEE.

Introduction: Point prevalence surveys (PPS) are increasingly used to examining and compare hospital antibiotic consumption. The aim of this study was to identify the (1) point prevalence of antibiotic use in one regional hospital and (2) compare PPS data from similar regional/general hospitals. Methods: Data were collected on all inpatients with an active antibiotic prescription and on all prescriptions issued in the emergency department over a 24-h period. Point prevalence data were obtained from three other regional/general hospitals. Results: The frequency of antibiotic use was hospital A = 29%, B = 38%, C = 34% and D = 37%. Overall, the most commonly prescribed antibiotic was co-amoxiclav (30%), followed by macrolides (12%). However, new generation broad-spectrum antibiotics, such as piperacillin/tazobactam or ciprofloxacin, were also commonly used. Prescribing for common conditions such as respiratory infection or cellulites showed diverse antibiotic selection. Conclusion: Point prevalence survey data using a standardised methodology could facilitate both local audit and national benchmarking to monitor antibiotic use. © Royal Academy of Medicine in Ireland 2011.
