ObjectivesHigh-quality feedback on different dimensions of competence is important for resident learning. Supervisors may need additional training and information to fulfil this demanding task. This study aimed to evaluate whether a short and simple training improves the quality of feedback residents receive from their clinical supervisors in daily practice.DesignLongitudinal quasi-experimental controlled study with a pretest/post-test design. We collected multiple premeasurements and postmeasurements for each supervisor over 2 years. A repeated measurements ANOVA was performed on the data.SettingInternal medicine departments of seven Dutch teaching hospitals.ParticipantsInternal medicine supervisors (n=181) and residents (n=192).InterventionHalf of the supervisors attended a short 2.5-hour training session during which they could practise giving feedback in a simulated setting using video fragments. Highly experienced internal medicine educators guided the group discussions about the feedback. The other half of the supervisors formed the control group and received no feedback training.Outcome measuresResidents rated the quality of supervisors’ oral feedback with a previously validated questionnaire. Furthermore, the completeness of the supervisors’ written feedback on evaluation forms was analysed.ResultsThe data showed a significant increase in the quality of feedback after the training F (1, 87)=6.76, p=0.04. This effect remained significant up to 6 months after the training session.ConclusionsA short training session in which supervisors practise giving feedback in a simulated setting increases the quality of their feedback. This is a promising outcome since it is a feasible approach to faculty development.

Subfertility represents one major challenge to enhancing dairy production and efficiency. Herein, we use a reproductive index (RI) expressing the predicted probability of pregnancy following artificial insemination (AI) with Illumina 778K genotypes to perform single and multi-locus genome-wide association analyses (GWAA) on 2,448 geographically diverse U.S. Holstein cows and produce genomic heritability estimates. Moreover, we use genomic best linear unbiased prediction (GBLUP) to investigate the potential utility of the RI by performing genomic predictions with cross validation. Notably, genomic heritability estimates for the U.S. Holstein RI were moderate (h2 = 0.1654 ± 0.0317–0.2550 ± 0.0348), while single and multi-locus GWAA revealed overlapping quantitative trait loci (QTL) on BTA6 and BTA29, including the known QTL for the daughter pregnancy rate (DPR) and cow conception rate (CCR). Multi-locus GWAA revealed seven additional QTL, including one on BTA7 (60 Mb) which is adjacent to a known heifer conception rate (HCR) QTL (59 Mb). Positional candidate genes for the detected QTL included male and female fertility loci (i.e. spermatogenesis and oogenesis), meiotic and mitotic regulators, and genes associated with immune response, milk yield, enhanced pregnancy rates, and the reproductive longevity pathway. Based on the proportion of the phenotypic variance explained (PVE), all detected QTL (n = 13; P ≤ 5e − 05) were estimated to have moderate (1.0% < PVE ≤ 2.0%) or small effects (PVE ≤ 1.0%) on the predicted probability of pregnancy. Genomic prediction using GBLUP with cross validation (k = 3) produced mean predictive abilities (0.1692–0.2301) and mean genomic prediction accuracies (0.4119–0.4557) that were similar to bovine health and production traits previously investigated.

Objective Farming is a hazardous occupation, with high rates of injury and death. FarmSafe, a whole-country approach, sought to address work-related injury on New Zealand sheep, beef, and dairy farms. More than 10 000 farmers participated in 630 workshops held over two years. This short communication presents the results of an impact evaluation of the FarmSafe Awareness Workshop (FSAW) in its first two years of operation. Methods All FSAW participants completed, and received credit for, formal educational assessments. Pass rates were used to assess safety knowledge, and a quasi-experimental design with intervention and comparison groups was applied to assess attitudes, safety behaviors, and environmental determinants of injury. Results An intervention (N= 111) and two comparison groups (Cl, N=409, and C2, N=78) completed before and after questionnaires. At follow-up, the intervention group (IG) showed a small improvement in attitudes toward safety (IG=79.3, C1=77.4; C2=77.4, P=0.035), but there were no differences between groups for personal safety practice or the safety environment of the farm. However, if a respondent registered their interest in the workshop, but a different person from the same farm attended, there was some improvement in the safety of the farm environment score. Conclusion Well-conducted safety training tailored to farmers was still not enough to change safety practice. Future interventions may be more likely to achieve progress if they are comprehensive, include environmental and enforcement features, and target more than one participant per farm.

We assessed relations between early temperament and behavior problems across 12 years in an unselected sample of over 800 children. Temperament measures were drawn from behavior ratings made by examiners who observed children at ages 3, 5, 7, and 9. Factor analyses revealed 3 dimensions at each age: Lack of Control, Approach, and Sluggishness. Temperament dimensions at ages 3 and 5 were correlated in theoretically coherent ways with behavior problems that were independently evaluated by parents and teachers at ages 9 and 11, and by parents at ages 13 and 15. Lack of Control was more strongly associated with later externalizing behavior problems than with internalizing problems; Approach was associated with fewer internalizing problems among boys; and Sluggishness was weakly associated with both anxiety and inattention, especially among girls. Lack of Control and Sluggishness were also associated with fewer adolescent competencies. These results suggest that early temperament may have predictive specificity for the development of later psychopathology.

Health related quality of life (HRQOL) measures are now accepted as indicators of efficacy in the palliative treatment of cancer. Utility measures may also provide valuable information yet they have been applied less frequently. To assess the application of a time trade-off (TTO) utility measure and its concordance with the Spitzer uniscale and quality of life index (QLI) 38 women with advanced, symptomatic breast cancer were studied over a 12 month period. The correlation coefficient for QLI and TTO values was 0.54 and for uniscale and TTO 0.62. Using generalized estimating equations the regression of TTO scores on QLI and uniscale scores was significant at baseline. In longitudinal analyses results were significant only for QLI. Although all participants completed the HRQOL measures only 24 (63%) were prepared to trade time. The remaining 14 (32%) stated they felt too well to trade. Those prepared to trade time recorded significantly worse mean HRQOL scores throughout the study compared to those who felt too well to trade and had tumors which showed a poorer response to therapy. In this preliminary study utility and HRQOL scores were generally favorable throughout the 12 month study period and showed fair to moderate concordance. Further research in larger patient groups is required to better define the relationships between utility and HRQOL measures.

To determine the efficacy of warm whirlpool, cold whirlpool, and contrast therapy in the treatment of delayed-onset muscle soreness. Subjects performed eccentric contractions of the elbow flexors and received 4 treatments: immediately postexercise and 24, 48, and 72 hours postexercise. Treatments consisted of 24-minute treatments with warm whirlpool, cold whirlpool, contrast therapy, or no treatment. Fifty-six sex-matched volunteers from the University of Pittsburgh. Measurements were taken at 5 assessment times: pre-exercise (0 hours); prior to treatment at 24, 48, and 72 hours postexercise; and at 96 hours postexercise. Dependent variables were degrees of resting elbow flexion, active elbow flexion, and extension; perceived soreness values on a Graphic Pain Rating Scale; and maximal voluntary isometric contraction. A repeated-measures analysis of variance (group by time) and Tukey post hoc analysis were used to determine which treatment groups differed significantly in returning subjects to pre-exercise values. Cold whirlpool and contrast therapy were found to return subjects to baseline values of resting elbow flexion and perceived soreness significantly more than warm whirlpool or no treatment (P < .01). Additionally, warm whirlpool was found to be more effective than no treatment in the return of resting elbow flexion (P < .01). These results suggest that cold whirlpool and contrast therapy are more effective than warm whirlpool or no treatment in alleviating delayed-onset muscle soreness in the elbow flexors.

Dysuria, a feeling of pain or discomfort during urination, is often caused by urinary tract infection but can also be due to sexually transmitted infection, bladder irritants, skin lesions, and some chronic pain conditions. History is most often useful for finding signs of sexually transmitted infection, complicated infections, lower urinary symptoms in males, and noninfectious causes. Most patients presenting with dysuria should have a urinalysis performed. Urine culture should be performed for infection to guide appropriate antibiotic use, especially for recurrent or suspected complicated urinary tract infection. Vaginal discharge decreases the likelihood of urinary tract infection, and other causes of dysuria, including cervicitis, should be investigated. If a patient has persistent urethritis or cervicitis with negative initial testing, Mycoplasma genitalium testing is recommended. Clinical decision rules may increase the accuracy of diagnosis with and without laboratory analysis. Evaluation and treatment of dysuria through a virtual encounter without laboratory testing may increase recurrent symptoms and antibiotic courses. Persistent symptoms after initial evaluation and treatment require further workup for infectious and noninfectious causes.

The paper presents the analysis of a power factor with capacitors banks, without series coils, used for improving power factor for a three-phase and single-phase inductive loads. In the experimental measurements, to improve the power factor, the Roederstein ESTAmat RPR power factor controller can command up to twelve capacitors banks, while experimenting using only six capacitors banks. Six delta capacitors banks with approximately equal reactive powers were used for experimentation. The experimental measurements were carried out with a three-phase power quality analyser which worked in three cases: a case without a controller with all capacitors banks permanently parallel connected with network, and two other cases with power factor controller (one with setting power factor at 0.92 and the other one at 1). When performing experiments with the power factor controller, a current transformer was used to measure the current on one phase (at a more charged or less loaded phase).
