Perceived Pressure

The effects of psychological pressure on perceiving the height of a jump bar just before starting a high jump run was investigated. University students (N = 14) training for a high jump event performed 15 trials (3 practice, 6 pressure, and 6 non-pressure) in counterbalanced order in their daily practice environment. The height of the bar was judged as significantly higher on pressure trials compared to non-pressure trials. A regression analysis indicated that participants who reported increased subjective perceived pressure tended to judge the bar to be higher. There was no significant difference between pressure and non-pressure trials for the performance index, defined as the success rate. This study provides the first evidence that environmental perceptions prior to executing a motor task under pressure may make performance of the task appear to be more difficult.

Background The objective of this survey was to assess retrospectively the interest of performing viscosupplementation using imaging guidance in patients suffering from ankle osteoarthritis (OA). Patients and Methods This is a multicenter retrospective survey using a standardized questionnaire. Fifty patients suffering from ankle OA and treated, in daily clinical practice, with a single intra-articular injection of a novel viscosupplement made of a combination of a non-animal cross-linked hyaluronan and mannitol, HANOX M-XL, were included in the survey. The injection procedure (imaging or landmark guidance), demographic data, patient's self-evaluation of pain, satisfaction, treatment efficacy, and tolerability were collected. Predictive factors of both efficacy and patient's satisfaction were investigated. Results The percentages of patients very satisfied/satisfied and not really satisfied/dissatisfied with the treatment were 68% and 32%, respectively. Efficacy was rated as very good, good, moderate, and poor by 38%, 30%, 12%, and 20% of the cases, respectively. Efficacy was unrelated to gender and age and was highly correlated with pain score ( P < 0.0001). In satisfied patients, the decrease in consumption of analgesics/non-steroidal anti-inflammatory drugs was >75% in 64% of the cases. Efficacy was significantly different with regard to imaging guidance. There was a statistically significant difference in efficacy and satisfaction between landmark-guided and imaging-guided injections ( P = 0.02). The success rate was 2.3 times higher in the imaging-guided group than in the landmark-guided group. No significant difference was found between patients injected under fluoroscopy or ultrasound guidance, despite a trend favoring ultrasound ( P = 0.09). Tolerability was rated as very good/good in 47 patients, moderate in two, and poor in one and was unrelated to the type of guidance. Conclusion This preliminary study suggests that the use of imaging guidance significantly optimizes the success rate of ankle viscosupplementation. No safety concern was observed.

The purpose of present study is to examine the role of learning strategies as moderator between meta-cognitive awareness and study habits among university students. Sample comprises of 200 students (100 male students and 100 female students) of various universities of Islamabad and Rawalpindi with age ranging from 18-25 years. In order to assess study variables questionnaires were used included Meta-Cognitive Awareness Inventory (Schraw & Dennison, 1994) measuring two-components of meta-cognition that are knowledge and regulation of cognition. Study habits demonstrated by the students were measured by the Study Habits Inventory (Wrenn, 1941). Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991) which includes motivation and learning strategies scales. In the present study, only the learning strategies section was utilized, which measures the cognitive strategies and resource management strategies. Results revealed positive correlation between research instruments and are also having good reliability. Regression analysis reflected that meta-cognitive awareness predicts study habits among university students. Regression analysis also suggested that learning strategies including resource management strategies and cognitive strategies significantly moderates the relationship between meta-cognitive awareness and study habits. It is also explored gender differences on learning strategies, meta-cognitive awareness and study habits. Future implications of the study were also discussed.

This study aims to determine the university students’ level of motivation in terms of different variables. A study group of this research has been designed through one of the non-random sampling methods, Using appropriate sampling, 606 students from Faculty of Education of C.U. have been involved in this study. Motivation scale in English Language Learning developed by Mehdiyev,Usta,Uğurlu (2015) was used as an instrument of data collection. T-test and one - way analysis of variance (ANOVA) were used to resolve problems of this research. As a result of the research the motivation level of university students hasn’t been revealed significantly different regarding to the gender variable. However, considering the t-test results of motivation scale dimensions, confidence, attitude and personal use, significant difference is seen in favour of women in personal use dimension. The level of language learning motivation of female students is higher than men’s regarding to personal use dimension. However, men’s and women’s views don’t differ significantly in attitude and confidence dimensions. University students don’t present significant differences in terms of birth place, parent’s education level, total motivation scores and confident, attitude and personal dimensions. Students’ motivation levels are seen not to be influenced by the places such as village, provision or city where they have spent the most of their lifetime. At the same time the findings revealed that parental status variable in terms of primary, secondary and university graduates has no effects on students’ motivation.

The aim of this study is to investigate the effects of participation in a 1-week summer camp on thehopelessness and self-esteem of the university students attending Sport Sciences Faculty. Participants were 36university students assigned to experiment group using a random procedure. Coopersmith Self-esteem and Beck Hopelessness Scales were completed at the beginning and end of the summer camp by designed the university. The obtained data were analysed in the SPSS 18.0 program and the significance level was taken as 0.05. The descriptive statistics, independent simple t test, paired simple t test and Pearson correlation were used for analyse the data in the study. According to the results of the research, no significant difference was observed in the comparison of the hopelessness and self-esteem levels between pre and post-test. In addition, there was a significant difference in the hopelessness level of male and female students but any significant difference was not observed in terms of self-esteem. There was a significant relationship between hopelessness and self-esteem pre and post-test. These result shows that a 1-week summer camp cannot change the hopelessness or self-esteem level. However, as the self-esteem rises, the rate of despair decreases whereas as the despair rises, the selfesteem decreases.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract Background The neutrophil–lymphocyte ratio (NLR), a presumed measure of the balance between neutrophil-associated pro-tumour inflammation and lymphocyte-dependent antitumour immune function, has been suggested as a prognostic factor for several cancers, including hepatocellular carcinoma (HCC). Methods In this study, a prospectively accrued cohort of 781 patients (493 HCC and 288 chronic liver disease (CLD) without HCC) were followed-up for more than 6 years. NLR levels between HCC and CLD patients were compared, and the effect of baseline NLR on overall survival amongst HCC patients was assessed via multivariable Cox regression analysis. Results On entry into the study (‘baseline’), there was no clinically significant difference in the NLR values between CLD and HCC patients. Amongst HCC patients, NLR levels closest to last visit/death were significantly higher compared to baseline. Multivariable Cox regression analysis showed that NLR was an independent prognostic factor, even after adjustment for the HCC stage. Conclusion NLR is a significant independent factor influencing survival in HCC patients, hence offering an additional dimension in prognostic models.

AbstractThe effects of intravenous sedation with midazolam on the cerebral function of elderly patients with severe dementia are unclear. This study aimed to evaluate its effects on parameters such as brainwaves and cerebral blood flow (CBF) and compare them between elderly individuals with dementia and without cognitive impairment. Ten patients with severe dementia and 10 without cognitive impairment were registered. The bispectral index (BIS) and normalized tissue hemoglobin index (nTHI), which reflects CBF using near-infrared spectroscopy, were measured. Midazolam was administered until a Modified Observer’s Assessment of Alertness/Sedation score of 2 was reached. The chi-squared, Mann–Whitney U, Wilcoxon signed-rank, and Friedman tests and multiple regression analysis were used for comparisons. Whereas a similar decline in BIS values was observed in both groups after midazolam administration (P < 0.018), there was a significant decrease by 9% in the nTHI of the dementia-positive group (P < 0.013). However, there was no significant difference in the nTHI between the dementia-positive and dementia-negative group according to the multiple regression analysis (P = 0.058). In the dementia-negative group, none of the measured values differed from the baseline values. In the dementia-positive group, sedation with midazolam resulted in a 9% decrease in the CBF.

Nail Involvement

Background:Nail psoriasis is an extreme diagnostic and therapeutic challenge and represents an enormous physical and psychological burden for affected patients.50% of patients with psoriasis vulgaris develop nail involvement (NailPso)during the course of their disease. NailPso is the strongest predictor of psoriatic arthritis (PsA). Through the synovio-enthesial concept we have learned that there is an anatomical-pathophysiological relationship between DIP joint, extensor tendon and nail matrix. We have observed in daily practice that hypervascularization (HV) in ultrasound Power Doppler (US-PD)the nail matrix may be a pathognomonic element in its own right. There are no data on this in the literature.Objectives:Is there a difference in the ultrasound PD examination of the DIP joint and nail area and in the capillary microscopy of the corresponding nail fold in patients with psoriasis vulgaris and nail psoriasis versus patients with psoriasis vulgaris without nail psoriasis.Methods:Monocentric prospective study of all consecutive patients with psoriasis vulgaris who have come to a rheumatic practice to clarify a PsA. Inaddition to demographic data, assessments (PASI,DLQI,CASPAR,GEPARD, DAS28, SJ,TJ,FFBH), clinical examination, a standardized ultrasound PD examination and capillary microscopy of the affected fingertips in PsO patients suffering from nail psoriasis was performed as well as corresponding examinations of the 2nd and 3rd finger right in PsO patients without nail involvement.Results:79 patients could be included during the study period. Thereof 25 PsO patients without nail involvement and 44 PsO patients with nail involvement. Since the patients were examined consecutively, the difference results. There was no difference in age, BMI and sex in both groups (Pso and NailPso). The Caspar criteria as classification criteria for a PsA were positive in 65% of the NailPso patients and positive in 50% of all PsO patients without nail infestation. Hypervascularization in the US-PD examination in the area of the nail matrix could be seen significantly more frequently in NailPso compared to non-NagelPso patients. Such a difference did not exist in the HV of the extensor tendons.Capillary microscopy showed a significant difference in the number of torsions/twist capillaries in NailPso compared to Pso patients without NailPso.Hypervascularization of the nail matrix is seen significantly more frequently in patients with psoriasis of the nail than in patients without psoriasis of the nail. Such a difference does not exist in DIP joint -extensor tendon- enthesitis. At the same time, torsions are significantly more frequently seen in capillary microscopy in NailPso than in patients without NailPso.Conclusion:The US-PD examination is a simple and non-invasive procedure which can be performed routinely in daily practice. The hypervascularization of the nail matrix should also make one think of nail psoriasis in the early stage of PsO, in order to be able to start early an appropriate therapy for this very stigmatizing and therapeutically extremely difficult manifestation of PsO. It seems to occur independently of extensor tendon synovitis as an independent manifestation phenomenon.The occurrence of torsions in capillary microscopy >50 % also seems to be groundbreaking for a NagelPso, whereby capillary microscopy is a temporal challenge in daily routine.References:§ The present study (7734-BO-S2018 Ethics Commission of the MHH, Medical School Hannover, Germany) contains parts of the PhD thesis of M.TöllnerDisclosure of Interests:Becker-Capeller Detlef Grant/research support from: Novartis, Speakers bureau: Pfizer, Soham El-Nawab-Becker: None declared, Malo Toellner: None declared, Andreas Kleinheinz: None declared, Torsten Witte: None declared

Background: Vascular factors and mitochondria dysfunction contribute to the pathogenesis of Alzheimer’s disease (AD). DL-3-n-butylphthalide (NBP) has an effect in protecting mitochondria and improving microcirculation. Objective: The aim was to investigate the effect of donepezil combined NBP therapy in patients with mild-moderate AD. Methods: It was a prospective cohort study. 92 mild-moderate AD patients were classified into the donepezil alone group (n = 43) or the donepezil combined NBP group (n = 49) for 48 weeks. All patients were evaluated with Alzheimer’s Disease Assessment Scale-Cognitive subscale (ADAS-cog), Clinician’s Interview-Based Impression of Change plus caregiver input (CIBIC-plus), Alzheimer’s Disease Cooperative Study-Activities of Daily Living (ADCS-ADL), and Neuropsychiatric Inventory (NPI) every 12 weeks. All patients were monitored for adverse events (AEs). The efficacy was analyzed using multivariate logistic regression analysis. Results: The multivariate logistic regression analysis showed that the changes of ADAS-cog score (OR = 2.778, 95% CI: [1.087, 7. 100], p = 0.033) and ADCS-ADL score (OR = 2.733, 95% CI: [1.002, 7.459], p = 0.049) had significant difference between donepezil alone group and donepezil combined NBP group, while the changes of NPI (OR = 1.145, 95% CI: [0.463, 2.829], p = 0.769), MMSE (OR = 1.563, 95% CI: [0.615, 3.971], p = 0.348) and CIBIC-plus (OR = 2.593, 95% CI: [0.696, 9.685], p = 0.156) had no significant difference. The occurrence of AEs was similar in the two groups. Conclusion: Over the 48-week treatment period, donepezil combined NBP group had slower cognitive decline and better activities of daily living in patients with mild to moderate AD. These indicated that the multi-target therapeutic effect of NBP may be a new choice for AD treatment.

ObjectivesThe study aimed to provide an association between dysmenorrhoea and academic performance among university students in Ethiopia. Further, the study attempts to determine the prevalence and associated risk factors of dysmenorrhoea.Design and methodInstitution-based cross-sectional study was conducted from 1 April to 28 April 2019. A semistructured and pretested self-administered questionnaire was used to collect data. Binary logistic regression analysis and one-way analysis of variance were performed to model dysmenorrhoea and academic performance, respectively.Setting and participantsEthiopia (2019: n=647 female university students).OutcomesThe primary outcome is dysmenorrhoea, which has been defined as painful menses that prevents normal activity and requires medication. The self-reported cumulative grade point average of students was used as a proxy measure of academic performance, which is the secondary outcome.ResultsThe prevalence of dysmenorrhoea was 317 (51.5%). The educational status of father (adjusted OR (AOR) (95% CI) 2.64 (1.04 to 6.66)), chocolate consumption (AOR (95% CI) 3.39 (95% 1.28 to 8.93)), daily breakfast intake (<5 days/week) (AOR (95% CI) 0.63 (0.42 to 0.95)), irregular menstrual cycle AOR (95% CI) 2.34 (1.55 to 3.54)) and positive family history of dysmenorrhoea AOR (95% CI) 3.29 (2.25 to 4.81)) had statistically significant association with dysmenorrhoea. There was no statistically significant difference in academic performance among students with and without dysmenorrhoea (F (3611)=1.276, p=0.28)).ConclusionsDysmenorrhoea was a common health problem among graduating University students. However, it has no statistically significant impact on academic performance. Reproductive health officers should educate and undermine the negative academic consequences of dysmenorrhoea to reduce the physical and psychological stress that happens to females and their families.
