Background: The impact of asymptomatic pronation on proximal joints during motion has not been well understood, and research on it remains limited. Therefore, the current study determines the effect of asymptomatic pronation of the foot on hip joint kinematics during gait. Methods: Forty participants were recruited for the study (20 with asymptomatic pronated feet and 20 with non-pronated feet). Foot assessment was conducted by navicular drop and rear- foot angle tests. Hip joint kinematics were measured via MVN Xsens system 3D-motion capture from sagittal, frontal and transverse planes during gait. An independent t-test was used to identify differences in kinematic variables. Results: Both groups were similar in characteristics, and there were no significant differences between the groups in age (P = 0.674) and BMI (P = 0.459). However, there was a significant difference in arch height (P = 0.001) and rear-foot angle (P = 0.001). Our findings showed there were insignificant differences between the asymptomatic pronated foot and non- pronated foot control groups in hip joint kinematics of sagittal (P = 0.618), frontal (P = 0.276), and transverse (P = 0.337) planes during a full gait cycle. Conclusion: Patients with asymptomatic pronation of the foot and non-pronation of the foot showed similar movement patterns of hip kinematics in all three planes. The findings of the present study highlight the need for clinicians to consider foot alignment when examining patients with asymptomatic pronation of the foot and non-pronation of the foot.

Abstract Introduction Untreated polycythemia leads to complications including thrombosis. Obstructive sleep apnea (OSA) is commonly associated with secondary erythrocytosis, which testosterone therapy can perpetuate. Effects of positive airway pressure (PAP) on elevated hematocrit (HCT) is unknown. We hypothesize PAP adherence can reduce HCT in men with OSA and polycythemia. Methods Retrospective chart review of male outpatients with newly diagnosed OSA and HCT≥45% at or 3 months before polysomnography (PSG) was conducted. Intervention group consisted of patients initiating PAP for OSA. HCT within 6 months of PAP initiation and PSG were recorded for intervention and control groups, respectively. Primary endpoint was time-to-HCT reduction of HCT<50% plus 3% decrease. Cox proportional-hazards analysis was used to assess time-to-HCT response. Demographics, smoking history, testosterone administration, STOP-Bang score, AHI, and PAP compliance data were obtained. Patients excluded if PAP not indicated, or if PSG, PAP compliance, or repeat HCT were unavailable. Results 41 men with OSA had HCT≥45%, of which 16 had HCT≥50%. Median age was 60 years and median BMI was 32 kg/m2. 28 started PAP. 21 met definition for PAP compliance within 6 months. Median AHI of intervention and control groups were 23 and 19 events/hr, respectively. Mean baseline HCT of both groups were 49 and 50, respectively. No significant difference in age, BMI, smoking history, testosterone therapy, and baseline HCT between both groups noted. 39% of intervention group exhibited HCT response at 1 or more longitudinal assessments, versus 38% of control. Intervention group had higher mean STOP-Bang than control (mean 5.9 vs. 4.6, p=0.01) and trended towards higher mean baseline AHI (27.4 vs. 19.0, p= 0.06). Time-to-event analysis controlling for STOP-Bang and AHI demonstrated PAP was not associated with time-to-HCT response (HR = 1.3, 95% CI = 0.4–4.4). In moderate-severe OSA patients, 40% of intervention group had HCT response compared to 14% of control, though difference was not significant (HR = 2.5, 95% CI = 0.3–20.0). Conclusion Moderate-severe OSA patients trended towards reduction in HCT with PAP, although not statistically significant. Testosterone administration did not affect HCT response to PAP in this cohort. Larger studies are required to determine HCT response to PAP in these patients. Support (if any):

The research aimed to check for difference in learning motivation between students learning online and students participating in modern classroom instruction. The study participants included students attending grades 5 to 8, divided into experimental (online classes) and control groups based on pre-testing. The results show that there is no statistically significant difference in motivation between the tested sub-samples. Student motivation for learning natural sciences declines with their years of schooling, but this is not statistically significant. It can be concluded that online teaching of Science and Biology as a learning tool can be as motivating as modern teaching using active classroom methods.

CONTEXT: Fibromyalgia is a syndrome characterized by chronic, diffuse musculoskeletal pain, and by a low pain threshold at specific anatomical points. The syndrome is associated with other symptoms such as fatigue, sleep disturbance, morning stiffness and anxiety. Because of its chronic nature, it often has a negative impact on patients' quality of life. OBJECTIVE: To assess the quality of life and anxiety level of patients with fibromyalgia. TYPE Of STUDY: Cross-sectional. SETTING: Rheumatology outpatient service of Hospital das Clínicas (Medical School, Universidade de São Paulo). METHODS: This study evaluated 80 individuals, divided between test and control groups. The test group included 40 women with a confirmed diagnosis of fibromyalgia. The control group was composed of 40 healthy women. Three questionnaires were used: two to assess quality of life (FIQ and SF-36) and one to assess anxiety (STAI). They were applied to the individuals in both groups in a single face-to-face interview. The statistical analysis used Student's t test and Pearson's correlation test (r), with a significance level of 95%. Also, the Pearson chi-squared statistics test for homogeneity, with Yates correction, was used for comparing schooling between test and control groups. RESULTS: There was a statistically significant difference between the groups (p = 0.000), thus indicating that fibromyalgia patients have a worse quality of life and higher levels of anxiety. The correlations between the three questionnaires were high (r = 0.9). DISCUSSION: This study has confirmed the efficacy of FIQ for evaluating the impact of fibromyalgia on the quality of life. SF-36 is less specific than FIQ, although statistically significant values were obtained when analyzed separately, STAI showed lower efficacy for discriminating the test group from the control group. The test group showed worse quality of life than did the control group, which was demonstrated by both FIQ and SF-36. Even though STAI was a less efficient instrument, it presented significant results, showing that fibromyalgia patients presented higher levels of anxiety, both on the state and trait scales. Thus, patients with fibromyalgia had higher levels of tension, nervousness, preoccupation and apprehension, and higher propensity towards anxiety. CONCLUSION: The three instruments utilized showed efficiency in evaluating fibromyalgia patients. FIQ was found to be the most efficient instrument for discriminating and assessing the impact of fibromyalgia on their quality of life. It can be concluded that such patients have a worse quality of life and higher levels of anxiety.

Purpose: Many health systems have implemented interventions to reduce the rate of heart failure readmissions. Pharmacists have the training and expertise to provide effective medication-related education. However, few studies have examined the impact of discharge education provided by pharmacy students and residents on patients hospitalized with heart failure exacerbations. Methods: This was a nonrandomized intervention study evaluating the impact of a pharmacy student and resident-led discharge counseling program on heart failure readmissions. The primary end point was the 30-day heart failure readmission rate. Secondary end points included self-reported patient understanding of medications, number of medication errors documented, and estimated associated cost avoidance. Results: A total of 86 and 94 patients were enrolled into the intervention and control groups, respectively. No statistically significant difference in readmission rates was detected between the intervention and the control groups. Thirty-four medication errors and discrepancies were documented, or 1 for every 2.5 patients counseled, resulting in an estimated cost avoidance of $4241 for the institution. Eighty-nine percent of patients who received discharge counseling agreed they had a better understanding of their medications after speaking with a pharmacy resident or student. Conclusions: There was no statistically significant difference in readmission rates; however, several medication errors were prevented, and a large percentage of patients expressed an improved understanding of their medications.

This study is a mixed method design which employed both quantitative and qualitative methods in order to investigate the impact of dialogic learning on students’ attention and academic achievement. Data were collected using several instruments, including: the Attention Network Test; academic performance tests and semi-structured interviews. Results of Analysis of Covariance (ANCOVA) indicated that there is a statistically significant difference between the mean scores of students of the experimental and control groups on the executive control in favor of the experimental group after controlling the IQ score and pre-test scores. Further, there is a statistically significant difference between the mean scores of student of the experimental and control groups on the academic achievement tests (except of mathematics) in favor of the experimental group. The qualitative data also supported the quantitative findings. Therefore, dialogic teaching has significantly greater and more positive changes on some aspects of attention and academic performance.

    The study sought to investigate the impact of limited and regulated code switching on the achievement of the Jordanian EFL learners. To achieve the aim of study, the use of code-switching was intended to be integrated within the code of conduct which made up the backbone of the class management.  The study sample consisted of (105) students from the eighth and ninth grades in Berein Secondary School, The Second Directorate of Education in Zarqa District. The subjects were divided into four groups; two experimental groups consisted of (51) male students who were taught through using code-switching. The other two control groups consisted of (52) male students who were taught the same content through the conventional strategy. Questionnaires were distributed into (100) male and female English teachers in different public and private schools to know their attitudes toward using code-switching in their daily lessons in EFL classrooms.  To achieve the goals of this study, the researcher chose both the quantitative design (achievement test) and the qualitative design (interviews and questionnaire) to conduct his study. Analysis of One-Way ANOVA was performed to test the statistical significance of the differences among groups. The results revealed that there was a statistical significant difference at the level (α =0.05) in the mean scores between the experimental groups and the control groups in favor of the experimental groups. The result showed that there were statistically significant differences between the mean scores of the subjects of the experimental groups who were taught through the code of conduct and using the code-switching.

Introduction The aim of this research was to evaluate the impact of a novel tele-rehabilitation system on self-reported functional outcomes compared to usual care during the first three months after stroke. Methods A parallel, two-arm, evaluator-blinded, randomised controlled trial was conducted. Adults aged ≥40 years who had suffered a stroke within four weeks of the start of the study were recruited from the general community. The intervention group received access to a novel tele-rehabilitation system and programme for three months. The primary outcome measures utilised were the frequency and limitation total scores of the Late-Life Function and Disability Instrument (LLFDI) at three months. Results A total of 124 individuals were recruited. The mean differences in the LLDFI frequency and limitation total scores at three months comparing the intervention and control groups were –3.30 (95% confidence interval (CI) –7.81 to 1.21) and –6.90 (95% CI –15.02 to 1.22), respectively. Adjusting for the respective baseline covariates and baseline Barthel Index also showed no significant difference between interventions in the LLFDI outcomes. Discussion The intervention and control groups self-reported similar improvements in functional outcomes. Tele-rehabilitation may be a viable option to provide post-stroke rehabilitation services in Singapore while reducing barriers to continue rehabilitation conventionally after discharge from hospital and encouraging more participation.

Introduction: A kinematic measurement method combining dynamic motion and imaging, which captures the behaviour of the hip at terminal motion, may offer improved diagnostic accuracy and enhance our understanding of the mechanics of femoroacetabular impingement (FAI). Methods: 3 embalmed cadaveric hip/pelvis specimens with implanted Roentgen Stereophotogrammetric Analysis (RSA) beads were mounted on a custom rig and imaged with a fluoroscope in four poses to simulate a clinical impingement examination: in hip extension and in three positions: near impingement, early impingement and late impingement while simulating a flexion/adduction/internal rotation manoeuvre. Hip joint kinematics were measured using 2 methods and compared: RSA (gold standard) and a custom 3-dimensional to 2-dimensional (3D–2D) image registration method which matches 3D models developed from CT to 2D fluoroscopic images. Results: Using RSA as the gold standard, bias and precision of hip joint rotations measured using 3D–2D registration demonstrated maximums of 1.64° and 3.96°, respectively. However, if the single outlier was removed, bias and precision were 0.55° and 1.38°. Bias and precision of translations had maximums of 0.51 mm and 0.77 mm, respectively. Conclusions: This 3D to 2D registration method may offer a clinically useful solution for dynamic assessment of hip impingement. If 5-mm translation and 10° of rotation represent a clinically significant difference in hip kinematics, the method’s accuracy of approximately 1 mm displacement and 1° rotation should enable detection of significant clinical differences.

Buprenorphine (BUP), a “synthetic opioid”, may cause memory impairment. This investigation aimed to study the impact of BUP on memory function related to acetylcholinesterase (AChE) activity inhibition in male rats. 24 male Wistar rats were randomly divided into three groups; control (C) and two treatment groups BUP (0.3 and 1) (n=8, for each group). BUP (0.3 and 1 mg/kg) was administrated subcutaneously once a day for 30 days. Normal saline 0.9% was injected in to control groups. In the end, animals were anesthetized and decapitated, and their hippocampus was dissected to assess AChE activity. There were no significant differences between the activities of AChE in the hippocampus in BUP-treated animals compared with controls. Besides, the activities of AChE in the BUP 0.3 group and BUP 1 group did not indicate a significant difference. These findings did not confirm the effect of BUP at doses of 0.3 and 1 mg/kg on memory function associated with the AChE activity inhibition.

Tobacco addiction is a major public health problem. Numerous scientific studies have been conducted on the harms of tobacco products. However, the number of intervention studies investigating the effect of long-term awareness of the harm of tobacco products on the Fagerström Test for Nicotine Dependence (FTND), Carbon Monoxide (CO), Carboxyhemoglobin (COHb) and Respiratory Function Test (RFT) are limited. Our goal is to investigate the impact of long-term scientific awareness on these parameters. The study was designed an intervention study on active and passive smoking participants and their control groups. Control groups were not given any training on the harms of tobacco products. When comparing the first and last weeks in active smoker intervention group (ASIG), the difference between FTND, FEV1, CO, and COHb parameters was observed to be statistically significant (p<0.05). The highest decrease in ASIG was in CO (↓60%) parameter and the highest increase was in the FEV1(↑%10) parameter. There was a significant difference both FEV1, FVC, FEV1/FVC (p<0.05) and CO parameters of passive smokers intervention group (PSIG). The highest decrease in PSIG was in the CO parameter (↓%65.8) and the highest increase was in the FVC (↑%10) parameter. Awareness programs may reduce the severity of addiction in active smokers and may help protect passive smokers. As awareness increases, positive changes in some vital parameters may be possible. Up-to-date programs and policies are needed to make easy and sustainable awareness of both active and passive smoking.
