Abstract Objectives: Lateral flexion range of movement (LF ROM) is used to assess and monitor recovery of side strain injury in athletes. This study established a reliable and pragmatic measure of LF ROM and investigated the stability of the measure over time in athletes. Design: 1) Cross-sectional reliability study and 2) Cohort longitudinal study. Setting: Elite cricket teams in COUNTRY-AAA and COUNTRY-BBB Participants: Cricket players Methods: 1) The intra- and inter-rater reliability of two methods of measuring LF ROM were assessed (distance to the floor or distance to fibular head). Ten healthy first-class cricket bowlers were tested by three experienced physiotherapists. Intra-class correlations (2,1) were calculated for absolute agreement for all 3 testers. 2) Professional cricket fast bowlers were recruited from COUNTRY-AAA and COUNTRY-BBB domestic and international competitions. Lateral flexion range of movement was measured monthly during the pre- and competitive season. A one-way repeated measures analysis of variance was performed to identify difference within the pre-season, within the competitive season, and between competitive seasons. Main Outcome Measures: Lateral flexion range of movement towards and away from the bowling arm. Results: Both methods had good intra- and inter-test reliability (ICC>0.84). As LF ROM to the floor was easier for clinicians it was used for the longitudinal study. Lateral flexion range of movement did not significantly alter throughout the pre- and competitive season or between seasons (p>0.05). Conclusions: This new method of describing LF ROM demonstrates good intra- and inter-rater reliability and stability over time and can be used as an outcome measure in side-strain injury.

AbstractThere is growing interest in the role of compassion in promoting health and well-being, with cross-sectional data showing an inverse correlation with loneliness. This is the first longitudinal study examining both compassion toward others (CTO) and compassion toward self (CTS) as predictors of mental and physical health outcomes including loneliness, across adult lifespan. We followed 552 women and 538 men in San Diego County for up to 7.5 (mean 4.8 and SD 2.2) years, using validated rating scales for CTO, CTS, and loneliness. Linear mixed-effects models were employed to examine age- and sex-related trajectories of CTO and CTS over time. Linear regression models were used to evaluate baseline and longitudinal relationships of CTO and CTS with mental well-being, physical well-being, and loneliness. CTS and CTO were weakly intercorrelated. Women had higher baseline CTO than men. While CTO was stable over time and across the lifespan, CTS scores had an inverse U-shaped relationship with age, peaking around age 77. There were significant baseline × slope interactions of both CTO and CTS predicting improvements in physical well-being in adults <60 years old. Increases in CTO and CTS predicted improvements in mental well-being. Higher baseline CTO and CTS as well as increases in CTO and CTS scores predicted lower loneliness scores at follow-up. Thus, CTO and CTS were associated with better mental well-being and loneliness across the adult lifespan, and physical well-being in younger adults, and are promising targets for interventions to improve health outcomes.

Background The cross-sectional area (CSA) records make an essential measurement for determining the mechanical properties of tendons, such as stress and strength. However, there is no consensus regarding the best method to record the CSA from different tendons. Purpose To determine intra- and inter-rater reliability for CSA measures from magnetic resonance imaging (MRI) of the following tendons: tibialis anterior; tibialis posterior; fibularis longus and brevis; and Achilles. Material and Methods We designed an observational study with repeated measures taken from a convenience sample of 20 participants diagnosed with acute or chronic ankle sprain. Two independent raters took three separate records from the CSA of ankle tendon images of each MRI slice. The intra-class correlation coefficient (ICC) and 95% limits of agreement (LoA) defined the quality (associations) and magnitude (differences), respectively, of intra- and inter-rater reliability on the measures plotted by the Bland–Altman method. Results Data showed very high intra- and inter-rater correlations for measures taken from all tendons analyzed (ICC 0.952–0.999). It also revealed an excellent agreement between raters (0.12%–2.3%), with bias no higher than 2 mm2 and LoA in the range of 4.4–7.9 mm2. The differences between repeated measures recorded from the thinnest tendons (fibularis longus and brevis) revealed the lowest bias and narrowest 95% LoA. Conclusion Reliability for the CSA of ankle tendons measured from MRI taken by independent rates was very high, with the smallest differences between raters observed when the thinnest tendon was analyzed.

Abstract Aims Limited cross-sectional studies have indicated that young children have some knowledge of the type of situations in which adults usually consume alcohol. However, it is unclear when and how this knowledge develops over time. This study tests the hypothesis that between the ages of 4 and 8, children become more knowledgeable about common drinking situations (e.g. ‘partying’) and uncommon situations (e.g. ‘driving’). Methods Data of two independent samples were used: a cross-sectional study (parents) and a three-wave longitudinal study (children). Parents and children were recruited via a convenience and random sampling strategy, respectively. To identify common, ambivalent, and uncommon drinking situations, parents (N = 158; 47% men) completed an online survey in which they indicated how common it is that any adult would drink alcohol in the 18 situations of the Dutch electronic appropriate beverage (eABT). Children (N = 329; 48.9% boys) completed the Dutch eABT to assess their knowledge of situations in which adults usually consume alcohol. Results General linear model repeated measures with post-hoc pairwise comparisons showed that parents’ perceptions of common, ambivalent, and uncommon situations in which adults consume alcohol predicted the initial level and the change over time in children’s knowledge of adults’ alcohol use in these situations. Conclusions Children aged 4–8 become increasingly knowledgeable about drinking norms in specific situations which implies that they know in what kind of situation alcohol consumption is a common human behavior. This knowledge may put them at risk for early alcohol initiation and frequent drinking later in life.

Research has shown that perfectionism predicts emotional experiences among amateur, professional and adolescent musicians. In examining these relationships, previous research has measured trait perfectionism and employed cross-sectional designs. The current study builds on existing research by examining whether perfectionistic self-presentation (as opposed to trait perfectionism) predicts negative and positive emotional experiences in music students over time. One hundred and forty-three music students ( M age 18.92 years, SD = 2.96) enrolled in music-related degree programs completed measures of perfectionistic self-presentation (perfectionistic self-promotion, non-display of imperfection, and non-disclosure of imperfection) and emotional experiences (positive and negative feelings) at the start, middle and the end of the academic year. Path analysis revealed that perfectionistic self-promotion at the start of the year predicted lower positive feelings in the middle of the year, and non-disclosure of imperfection in the middle of the year predicted lower positive feelings at the end of the year. In addition, negative feelings in the middle of the year also predicted higher non-disclosure of imperfection at the end of the year. The findings suggest that the desire to present oneself perfectly and avoid disclosure of imperfections may contribute to less positive emotional experiences among music students.

Abstract Background Cognitive alterations are a central and heterogeneous trait in psychotic disorders, driven by environmental, familial and illness-related factors. In this study, we aimed to prospectively investigate the impact of high familial risk for cognitive alterations, unconfounded by illness-related factors, on symptomatic outcomes in patients. Methods In total, 629 probands with non-affective psychosis and their sibling not affected by psychosis were assessed at baseline, 3- and 6-year follow-up. Familial cognitive risk was modeled by three cognitive subtypes (‘normal’, ‘mixed’ and ‘impaired’) in the unaffected siblings. Generalized linear mixed models assessed multi-cross-sectional associations between the sibling cognitive subtype and repeated measures of proband symptoms across all assessments. Between-group differences over time were assessed by adding an interaction effect of time and sibling cognitive subtype. Results Probands affected by psychosis with a sibling of the impaired cognitive subtype were less likely to be in symptomatic remission and showed more disorganization across all time points. When assessing differences over time, probands of siblings with the impaired cognitive subtype showed less remission and less improvement of disorganization after 3 and 6 years relative to the other subtypes. They also showed less reduction of positive, negative and excitement symptoms at 6-year follow-up compared to probands with a sibling of the normal cognitive subtype. Conclusions Cross-sibling pathways from higher levels of familial cognitive vulnerability to worse long-term outcomes may be informative in identifying cognition-related environmental and genetic risks that impact psychotic illness heterogeneity over time.

ABSTRACTThe Aging in Manitoba (AIM) project includes nearly 9,000 seniors who have been interviewed. Three independent cross-sectional samples (i.e. 1971, 1976, 1983) were subsequently followed (1983–1984, 1990), producing cross-sectional and longitudinal data. A major goal of this paper was to examine non-response over time and representativeness of the panel of AIM survivors. This involved analysis of non-response, calculations of completion/response rates, and comparisons of demographic variables across the AIM sample and the broader Manitoba and Canadian populations. Non-response was very low (4.6% in 1983–1984, 5.0% in 1990) and did not appear to be dependent on such factors as location, gender, education level, or nationality descent. The 95.0 per cent completion rate compares favourably with other longitudinal studies, demonstrating the value of employing rigorous tracking procedures. These findings suggest that attempts to minimize bias and selective attrition in the AIM study have been successful.

The stability of intravenous famotidine in dextrose 5% injection (D5W), NaCl 0.9% injection (NS), and sterile water for injection stored in polyvinyl chloride (PVC) syringes at 4°C for 14 days was studied. The concentration of famotidine samples was determined at time 0, 7 days, and 14 days by reverse-phase high-performance liquid chromatography. Samples were inspected for visual changes and tested for changes in pH. Results of the HPLC analysis indicated that the famotidine samples remained within 94-100 percent and 99-103 percent of the time 0 concentrations at 7 and 14 days, respectively. Repeated measures analysis of variance demonstrated a significant time effect on famotidine concentration as concentrations changed over time (p<0.01). This change was small in magnitude, however, and concentrations decreased at 7 days and increased at 14 days. Famotidine is stable at a concentration of 2 mg/mL in D5W, NS, and sterile water for injection stored in PVC syringes at 4°C for 14 days.

The Stability

The ‘fear of crime’ is a politically important measure, and much is made of year to year changes in levels when generated by repeat cross-sectional national surveys such as the British Crime Survey. Data from the first two waves of a longitudinal survey of the fear of crime undertaken in Trinidad indicate that identical year on year fear levels regularly conceal considerable gross changes in reported fear, many of which are mutually cancelled in the calculation of net year- on-year fear levels. These results question either or both of the stability of the fear of crime, and of measures used to assess it.

We investigated the stability of adrenocorticotropic hormone (ACTH) in plasma after freezing for different lengths of time. The plasma ACTH concentrations of 12 horses were measured on day 0 (baseline) and over time, after stimulation with thyrotropin-releasing hormone. Samples were stored at −80°C for 3, 7, 30, 60, and 90 d, or at −20°C for 3, 7, 30, and 60 d, or between ice packs at −20°C for 3 and 7 d prior to determination of ACTH concentration. ACTH concentrations were compared to baseline (non-frozen day 0 plasma) for each storage method using a mixed model with repeated measures in which each horse served as its own control and day was the repeated effect. Statistical significance was set at p ≤ 0.05, and 0.05 < p < 0.10 was considered a trend. Plasma ACTH frozen at −20°C or at −80°C resulted in degradation of ACTH compared to baseline samples at 60 and 90 d respectively. There was no degradation of ACTH after 7 d when stored between ice packs, or before 30 d at −20°C, or before 60 d at −80°C.
