ObjectiveTo determine the prevalence of orthostatic hypotension (OHypo) and hypertension (OHTN), respectively after a concussion in collegiate athletes.BackgroundOrthostasis causes a gravity-dependent redistribution of blood volume to the lower extremities. The baroreflex coordinates the cardiovascular autonomic nervous system to mitigate aberrant changes in systolic blood pressure (SBP). In autonomic dysfunction (AD), impaired accommodation may lead to a clinically significant? SBP decreases (OHypo: SBP fall = 20 mm Hg) or paradoxical increases (OHTN: SBP rise = 20 mm Hg) within 3 minutes of assuming the standing (STND) posture. Concussion injuries may induce a transient state of AD. A clinical approach to surveil this state has yet to be defined.Design/MethodsA prospective study was performed in 36 concussed (gender: 23 female, 13 male; age: 20 ± 1 years; height: 1.75 ± 0.12 meters; weight: 73 ± 14 kilograms) and 20 non-concussed athletes (gender: 12 female, 8 male; age: 21 ± 2 years; height: 1.74 ± 0.15 meters; weight: 72 ± 18 kilograms). Continuous beat-to-beat SBP was collected for 10-minutes in a resting supine position (SUP) and then for 3-minutes in the STND position within 48 hours (48H) of concussion. The average SBP was computed from the difference between SUP and the final 15 seconds of STND. SBP were then categorized: Normal (NR: SBP -15 to +15 mm Hg); Borderline OHypo (BordOHypo: SBP −16 to −19 mm Hg) and OHTN (BordOHTN: SBP +16 to +19 mm Hg); OHypo; and, OHTN.ResultsIn concussed athletes, the SBP prevalence rates were 42% NR, 31% OHypo, 11% OHTN, 11% BordOHTN, and 6% BordOHypo compared to 90% NR, 5% OHypo and 5% OHTN in the non-concussed athletes. ?2 test revealed a significant difference in this distribution (p = 0.012).ConclusionsWithin 48H of concussion injury, a combined 42% of injured athletes had an abnormal SBP response to orthostasis and a further 6% had borderline responses that warrant re-evaluation. The incidence rates for each circumstance exceeded the control group.

Suicide in probation services is far higher than the general population. This paper presents secondary analysis of data previously used to evaluate the outcome of delivering psychological treatment to probationers in London. A sample of probation service users who screened positive for clinically significant symptoms of distress and were subsequently assessed and offered treatment ( n = 274) were allocated retrospectively to one of three groups: those with a history of suicidal ideations but no suicide attempts (ideation group), those with a history of a suicidal act (attempt group) or a control group where suicide was not evident (no history group). Results indicate no significant difference between the ideation and the attempt groups, but significant differences between these and the no history group. The findings are discussed within the context of the suicide ideation-to-action models that have been debated in other offender settings. We conclude that a more nuanced understanding of suicidal acts and suicide attempts is required in probation services including a prospective study that tests the ideation-to-action model.

Background. Currently, the introduction of pre-rehabilitation programs has shown its effectiveness in various sections of abdominal surgery, however, its role in surgical pancreatology is still not entirely clear Aim. To study the effectiveness of the implementation of pre-rehabilitation programs (preoperative exercises and diet therapy) during the waiting period for surgery and their effect on the physical and nutritional status, as well as postoperative complications and the duration of hospital stay in patients who underwent pancreatoduodenal resection. Material and methods. A prospective study was carried out including 44 patients who underwent pancreatoduodenal resection. The patients included in the study were divided into two groups. The control group (23 patients) preoperative preparation, which was carried out according to the standard method. The main group consisted of 21 patients who underwent pre-rehabilitation. Results. Among the patients in the compared groups, there were no statistically significant differences in age, gender, ASA and body mass index, concomitant diseases, and basic laboratory parameters. In the group of patients who underwent pre-rehabilitation, there was a statistically significant increase in the 6-minute walk test (p = 0.02), as well as the prognostic nutritional index (p = 0.01). There was no statistically significant difference between the compared groups in the incidence of major postoperative complications (Clavien - Dindo III / IV) (p = 0.8), clinically significant pancreatic fistulas (p = 0.5), and mortality (p = 0, 6), however, in the pre-rehabilitation group there was a significant decrease in the incidence of gastric evacuation disorders in comparison with the control group (9.5% versus 34.8%, p = 0.04). The average postoperative bed-day was 16.1 5.6 days in the pre-rehabilitation group and 19.8 6.2 days in the control group (p = 0.04). Conclusion. The introduction of pre-rehabilitation in patients undergoing pancreatoduodenal resection is effective and allows improving the physical and nutritional status of the patient, reducing the postoperative bed day and reducing the frequency of delayed gastric evacuation.

Abstract OBJECTIVE To explore the effect of group medical games on the hospitalization adaptability of pediatric patients with neuro tumor. METHODS pediatric patients with neuro tumor (age:6 to 13 years) who were treated in hospital from June to December 2019 and were hospitalized for 1 month to 2 months. 29 pediatric patients(mean age:9y) were selected as the control group and treated as usual; 26 pediatric patients(meanage:8y) were selected as the experimental group for group therapeutic play intervention. Interventions last Monday, Wednesday and Friday of each week, with an average duration of one hour. Group medical play include: medical picture book education, medical preview game, emotional games, social table games. Two groups completed self-made questionnaires at the time of admission and two weeks after admission, including: diet, sleep, compliance, and social status, hospital adaptation and other related issues, two groups completed a satisfaction questionnaire after two weeks of admission, recorded analysis and compared the difference of questionnaire data and satisfaction of the two groups of pediatric patients. RESULTS There was no statistical difference in age and sex between the two groups, and there was no significant difference in baseline RESULTS: The re-test results showed that the experimental group was significantly better than the control group in terms of social status, hospital adaptation, compliance and family satisfaction(p＜0.05). CONCLUSION Group medical games can effectively improve the adaptability, compliance and family satisfaction of pediatric with neuro tumor.

The Relationship

Abstract Background Pulmonary vascular resistance (PVR) is an essential parameter assessed during cardiac catheterization. It is used to confirm pulmonary vascular disease, to assess response to targeted pulmonary hypertension (PH) therapy and to determine the possibility of surgery, such as closure of intra-cardiac shunt or transplantation. While PVR is believed to mainly reflect the properties of the pulmonary vasculature, it is also related to blood viscosity (BV). Objectives We aimed to assess the relationship between measured (mPVR) and viscosity-corrected PVR (cPVR) and its impact on clinical decision-making. Methods We assessed consecutive PH patients undergoing cardiac catheterization. BV was assessed using the Hutton method. Results We included 465 patients (56.6% female, median age 63y). The difference between mPVR and cPVR was highest in patients with abnormal Hb levels (anemic patients: 5.6 [3.4–8.0] vs 7.8Wood Units (WU) [5.1–11.9], P<0.001; patients with raised Hb: 10.8 [6.9–15.4] vs. 7.6WU [4.6–10.8], P<0.001, respectively). Overall, 33.3% patients had a clinically significant (>2.0WU) difference between mPVR and cPVR, and this was more pronounced in those with anemia (52.9%) or raised Hb (77.6%). In patients in the upper quartile for this difference, mPVR and cPVR differed by 4.0WU [3.4–5.2]. Adjustment of PVR required Conclusions We report, herewith, a clinically significant difference between mPVR and cPVR in a third of contemporary patients assessed for PH. This difference is most pronounced in patients with anemia, in whom mPVR significantly underestimates PVR, whereas in most patients with raised Hb, mPVR overestimates it. Our data suggest that routine adjustment for BV is necessary.

Neuropsychological Tasks

The literature on the neuropsychology of Attention Deficit Hyperactivity Disorder (ADHD) is plagued by inconsistent findings, which are usually attributed to a variety of extraneous variables. One of the most inadequately explored of these variables is the difference between ADHD children attending remedial and mainstream schools. This study aimed to investigate whether the performance of remedial and mainstream school ADHD boys differs on relevant neuropsychological tasks. The sample consisted of three groups of 8- to 12-year-old boys. Two of these groups consisted of children with ADHD: one from remedial schools and one from mainstream schools. The third group was made up of participants without ADHD, who attended mainstream schools. The performance of the remedial school learners on the Stroop, Lurian and cancellation tasks was investigated and compared to a mainstream school ADHD sample. The performance of the ADHD group as a whole was compared with that of a control group. No significant difference in performance was found between the two ADHD groups, except for the length of time taken to read words in the control condition of the Stroop. The control group out-performed the ADHD samples on the Stroop, Lurian and cancellation tasks. The findings suggest that mainstream and remedial ADHD boys do not differ in the severity of their executive deficits, but that boys with ADHD attending remedial schools may be more likely to have another learning disorder than their counterparts at mainstream schools.

Given that children with attention deficit hyperactivity disorder (ADHD) are more impulsive than peers, this study explored whether they are correspondingly more creative, and whether creativity declines when impulsivity is decreased through methylphenidate (Ritalin) therapy. A repeated-measures quasi-experimental design was used to compare the performance of 19 boys with previously diagnosed ADHD and 21 comparison boys aged 8 through 11 on two administrations of alternate forms of the Torrance Tests of Creative Thinking-Figural (nonverbal). Boys with ADHD received prescribed methylphenidate only for the first session. Overall, mean Torrance summary scores for comparison boys (mean = 115.1, SD = 16.1) were higher than for boys with ADHD (mean = 107.6, SD = 12.7). However, the difference between means was small (7%) and did not meet the 25% criterion for a clinically significant difference. No changes in performance over time (comparison group) or medication state (ADHD group) were observed. These data suggest that, when measured nonverbally, the creative thinking performance of boys with ADHD is not superior to that of peers who do not have ADHD. Regarding the effects of methylphenidate, prescribed therapy did not influence performance on this measure of creative thinking.

Implementation of animation as an Arabic language teaching aid is an innovation in creating an atmosphere that can influence student achievement. This study aimed to identify the effectiveness of the use of animation in Arabic language teaching and learning among diploma students at Universiti Sultan Zainal Abidin (UniSZA), Terengganu, Malaysia. A total of 66 diploma students were randomly selected and divided into experimental group (n = 33) and control group (n = 33). The results obtained from the data collected from pre-and post-test for each group were analyzed using t-test in SPSS version 17.0. The results showed a significant difference of (t = 8789, df = 64, p <0.05) between the achievement of the experimental group and the control group in the post test. The difference in mean score of the experimental group and the control group was 33.03. This shows that there is significant improvement in Arabic language according to the groups. The difference prove that the use of animation in learning sessions contribute to the achievement of students in the Arabic language. This study advocate the idea that animation applications can be integrated as part of language teaching aid to positively improve student achievement, classroom learning environment and student motivation.

Gastrocnemius Tightness

Category: Other Introduction/Purpose: Gastrocnemius tightness (GT) is thought to predispose patients to multiple musculoskeletal pathologies including back pain, plantar fasciitis, and metatarsalgia. It is thought to be especially prevalent in patients with foot and ankle pathology (FAP) and consequently there is an emerging trend to perform lengthening / release procedures in this patient group. However, it is not clear what proportion of the normal population has GT and how this differs in patients with FAP. We set out to investigate what the incidence and degree of GT in the foot and ankle population is compared to the normal population. Methods: This was a prospective study comparing GT in a cohort of patients with FAP with GT in controls matched for age, gender, and ethnicity. The control group consisted of healthy adult volunteers and the FAP group consisted of patients presenting to our Foot & Ankle unit. Patients with previous surgery, tendoachilles tightness, or ankle arthritis were excluded. GT was measured using a digital inclinometer and the lunge test. It was calculated as the difference between maximal ankle dorsiflexion with the knee extended and with the knee flexed. Data on the control group was collected first and a power calculation suggested a FAP cohort size of 91 feet was required to detect a 2° difference in GT (a= 0.05, ß = 0.05, Ratio 3:1). Results: After case-matching 97 FAP cases were paired with 291 controls for analysis. Mean GT was 8.0° ±5.7° (range: 0-21°) in FAP patients versus 6.0° ±3.5° (range: 0-16°) in controls (p<0.001). Regression analysis demonstrated demographics including BMI and activity level were not significant determinants of GT in the FAP group (r=0.141, p=0.599). Subgroup analysis of the FAP group revealed a mean GT of 10.3° ±6.0° in patients with forefoot pathology (FoP) versus 6.9° ±5.3° in the other FAP patients (NFoP) (p=0.008). When comparing the NFoP group to the controls, there was no difference in GT (p=0.188). In total 21 FAP patients (21.6%) and 12 FoP patients (37.5%) had GT greater than 2 standard deviations of the control group (Figure 1). Conclusion: This population based study demonstrates increased GT in the FAP population versus the normal population; however, in patients without forefoot pathology, this difference may not be clinically relevant. Over a third of patients with forefoot pathology have GT which is greater than the normal population range. We conclude that not all patients with foot and ankle pathology have inherently increased GT, compared with the normal population, but it is reasonably common in patients with forefoot pathology. Further work is required to define what degree of GT may be considered significant, to determine which patients will benefit from surgical treatment.

Abstract Aim The purpose of this study was to compare two types of conventional radiographic film: Ekta-speed plus and Insight (Eastman Kodak Co, Rochester NY, USA) for accuracy of measurements of approximal bone loss. Methods and Materials Four dried human mandibles with complete dentition were selected. Radiographic images were made with a standardized technique. Mesial and distal bone levels on the mandibular premolar and molar teeth were measured on the two types of radiographs (Ekta-speed plus and Insight) by nine observers. The data obtained by the observers were compared with the primary investigators’ corresponding measurements, which served as “the ground truth” for this study. Results The results of the analysis of variance (ANOVA) demonstrated a significant difference for the Ektaspeed plus film (p = .001), but the difference was not clinically significant. The level of intra-rater reliability was high for the observers (0.969 to 0.990). Conclusion Performance of Ekta-speed plus and Insight films was found to be similar.

The present study investigates the effect of negative emotions (focusing on disappointment, sadness and regret) on cognitive schemas. The sample consist in students from the University of Bucharest (convenience groups). A univariate unifactorial experimental design was used, as the current study had one independent variable, negative emotions, and a dependent variable, cognitive schemas, which was measured with the Core Beliefs Questionnaire instrument. We applied T test for independent samples, using SPSS. The t test was statistically significant, t (45) = 2.57, p <0.05. The confidence interval (95%) for the difference between the averages is between 2.95 and 24.35. After applying the intervention, the evaluated sample (M = 43.17, SD = 29,074) showed a statistically significant difference compared to the control group (M = 29.52, SD = 11.257). The data collected support the main research hypothesis of the study, negative emotions can bring about changes in certain cognitive schemas by modifying, altering or disrupting them.
