Background: Depression, as the second leading cause of dysfunction, is one of the most common mental health disorders. Given that micronutrients have always played a significant role in all physical and psychological aspects of individuals. This study was conducted to investigate the relationship of dietary intake of Selenium, Magnesium, Zinc, and anthropometric profiles with depression in female students at Zahedan University of Medical Science, Zahedan, Iran. Methods: In this cross-sectional study, 200 female medical students of Zahedan University of Medical Sciences participated. The amount of dietary intake of Selenium, Magnesium, and Zinc were measured by Food Frequency Questionnaire (FFQ). For determining the depression score, Beck anxiety questionnaire was administered. To analyze the data, SPSS 22 software was used. Results: The mean of age, body mass index, waist-to hip ratio and waist-to-height ratio were 23.41 ± 2.26 years, 23.54 ± 4.49 kg/m2, 0.85 ± 0.08, and 0.59±0.10, respectively. The mean daily intake of Magnesium, Zinc, and Selenium were 196.37 ± 42.08 mg, 7.38 ± 3.41 mg, and 106.52 ± 31.69 mg, respectively. The mean of depression score was 31.21±10.58. Zinc and Magnesium intake had a significantly strong inverse relationship with depression score and anthropometric indices. Conclusions: The findings showed that Zinc and Magnesium intake as well as anthropometric indices had a significant inverse relationship with depression score. However, the association between Selenium intake and depression score was not significant.

Tethered swimming tests are applied to evaluate propulsive forces in crawl stroke and may also be used to evaluate force applied by the movement of lower (leg kicking) and upper limbs (arm stroke). Considering the large number of recreational swimmers, this tool may be useful for coaches to evaluate the technique and force production by swimmers. As little attention has been paid to the application of these tests with recreational swimmers, the aims of this study were to verify the repeatability of the tethered swimming test for arm stroke, leg kicking and crawl stroke and to verify the relationship between performance in a 50-m test and in the tethered test with recreational swimmers. In this case, repeatability was defined as the agreement between the results of two successive evaluations. Ten male swimmers performed two 30-s maximal intensity tethered swimming tests with leg kicking, arm stroke and crawl stroke and three 50-m crawl stroke tests. Repeatability was found for mean force of all tests and for impulse evaluated in crawl stroke. Inverse relationship of the time to complete 50 m with the maximum and mean forces and with the impulse in the crawl stroke and an inverse relationship between time to complete 50 m and the mean force in the leg kicking were observed. Therefore, results from full tethered swimming tests applied with recreational swimmers may help swimming coaches.

The present report is based on reanalysis of data of Marisi (1969) in order to examine the relationship of consistency of motor response among the component responses of a single motor task. 120 high school Ss were tested on a special task, the rho. A single trial on this motor task can be logically separated into three component motor responses: reaction time, a short circular movement, and a short linear movement. The results indicated that consistency of motor response was moderately reliable within the response components but tended to be response-component specific. Further, both the reliability and specificity of motor-response consistency were independent of the size of the mean performance scores.

Blood Mercury Concentration

Wide discrepancies have been observed between controlled and uncontrolled intake studies of the relationship of blood mercury concentration to intake of mercury. The probable reason for the apparent discrepancies is that the within-subject variation of mercury intake in the uncontrolled studies was almost certainly considerably larger than the within-subject variation in blood mercury concentration; in these circumstances, the apparent slope obtained from a linear regression of blood mercury on intake will invariably be much smaller than the true slope. Studies of the exposure or intake of any substance should therefore include a consideration of the likely within-subject variation in the exposure or intake relative to that in the effect.

The Relationship

Undifferentiated mesenchymal (UM) cells, the progenitor cells of the cartilage layer, have been assigned a significant role in TMJ articular tissue maintenance. This was based on reports of UM cell reduction with increased soft-tissue thickness for the condyle and temporal component. However, the strength of this inverse relationship was not presented and remained unclear. The purpose of the present study was to assess the strength of the correlation between UM cell presence and soft-tissue thickness in young adult TMJs at autopsy. Sagittal histological sections from the central thirds of 50 joints were evaluated with respect to articular soft-tissue thickness, histological character, and UM cell presence in the condyle and temporal component. The superior sector ofthe condyle and the articular eminence showed the greatest variability in soft-tissue thickness and were the only areas to show localized UM cell absence. The eminence was the only location to show an inverse relationship between soft-tissue thickness and UM cell presence, and this was consistent in both an ANOVA (p = 0.0016) and a Spearman correlation analysis. However, the strength of this correlation was only moderate (rho = -0.52), and no such relationship was observed in any other location. This study suggests that the relationship between UM cell presence and soft-tissue thickness is more complex than previously hypothesized and that the contribution of UM cells to articular tissue maintenance has been overstated, while other biological processes were overlooked.

Electroencephalogram Eeg

The aim of this exploratory study was to examine the relationship of electroencephalogram (EEG) arousals to breathing patterns and the relationship of both arousals and breathing patterns to arterial oxygenation during sleep in older adults. Five older adults were monitored using standard polysomnography. Records were divided into 5-min segments and breathing patterns identified based on the level of respiratory periodicity and the variability in the frequency of breathing cycles. Standard criteria were used to determine sleep states and occurrence of EEG arousals. High respiratory periodicity was seen in 23% of the segments, whereas 24% had low respiratory periodicity with minimal variability in the frequency of breathing (Type A low respiratory periodicity) and 53% had low respiratory periodicity with high variability in the frequency of breathing (Type B low respiratory periodicity). Nearly all (97%) segments with high respiratory periodicity had EEG arousals, whereas fewer segments (33%) with low respiratory periodicity had arousals, regardless of the stage of sleep. Desaturations occurred more often in segments with high respiratory periodicity, F (2,4) = 57.3, p < .001, but overall, the mean SaO2 of segments with high respiratory periodicity did not differ from levels seen in segments with low respiratory periodicity, F( 2,4) = 0.77, ns. Our findings suggest that high respiratory periodicity is a common feature of EEG arousals and, in older adults, may be important for maintaining oxygen levels during desaturations during sleep.

ObjectivesThe aim of this study is to analyse the relationship between smoking andaltitude mountain sicknessin a cohort of travellers to 2500 metres above sea level (masl) or higher.SettingTravel Health Clinic at the Hospital Universitari de Bellvitge, in Barcelona, Spain.ParticipantsA total of 302 adults seeking medical advice at the travel clinic, between July 2012 and August 2014, before travelling to 2500 masl or above, who agreed to participate in the study and to be contacted after the trip were included. Individuals who met the following criteria were excluded: younger than 18 years old, taking carbonic anhydrase inhibitors for chronic use, undergoing treatment with systemic corticosteroids and taking any medication that might prevent or treat altitude mountain sickness (AMS) prior to or during the trip. The majority of participants were women (n=156, 51.7%). The mean age was 37.7 years (SD 12.3). The studied cohort included 74 smokers (24.5%), 158 (52.3%) non-smokers and 70 (23.2%) ex-smokers. No statistical differences were observed between different sociodemographic characteristics, constitutional symptoms or drug use and smoking status.OutcomesThe main outcome was the development of AMS, which was defined according to the Lake Louise AMS criteria.ResultsAMS, according to the Lake Louise score, was significantly lower in smokers; the value was 14.9%, 95% CI (6.8 to 23.0%) in smokers and 29.4%, 95% CI (23.5 to 35.3%) in non-smokers with an adjusted OR of 0.54, 95% CI (0.31 to 0.97) independent of gender, age and maximum altitude reached.ConclusionsThese results suggest that smoking could reduce the risk of AMS in non-acclimated individuals. Further studies should be performed in larger cohorts of travellers to confirm these results. Despite the results, smoking must be strongly discouraged because it greatly increases the risk of cardiorespiratory diseases, cancer and other diseases.

Introduction: Non-motor symptoms in Parkinson's disease are often not well recognized in clinical practice. Non-motor symptoms questionnaire (NMSQuest) is a simple instrument that allows patients or caregivers to report non-motor symptoms in a practical manner. Objective: We attempted to determine the prevalence of non-motor symptoms in three hundred Parkinson's disease outpatients. Results: The mean total non-motor symptoms was 12.41, ranging from 0 to 27 of a maximum of 30. At least one was present in 99.3% of patients. A progressive increase in mean total score was observed across each 5-year interval. Depression domain scored the most “positive” answers while urinary and anxiety /memory were secondly and thirdly most prevalent respectively. Conclusion: The large number of patients included in this study allowed evaluation of the occurrence of non-motor symptoms in early and advanced disease in addition to the relationship of these kinds of symptoms with progression of disease.

Objectives. Studying the relationship of autonomy and attachment in relationships with parents with real self-determination in students. Background. The growing world globalization, intercultural contradictions, confrontation within society seriously complicate the path of self-determination of modern youth. At the same time, due to technical progress and digitalization of the communication and education environment, there are significant transformations in the interaction of people in almost all spheres, including in the family. Therefore, the question of studying the most important aspects in the relationship of young people with their parents for real self-determination is especially acute. Study design. The work studied the indicators of real self-determination, attachment to parents and autonomy among students. The presence of a relationship between these parameters was established by calculating the Spearman correlation coefficient. Participants. 60 college students aged 18 to 21. Measurements. Methodology “Scale of adult attachment for close relationships”; autonomy questionnaire (authors O.A. Karabanova and N.N. Poskrebysheva); questionnaire “ORS” (author D.A. Krasilo). Results. An inverse relationship of indicators of real self-determination of students with the level of intimacy and the level of anxiety (scales of attachment to parents) was established. A direct relationship was revealed between the indicators of real self-determination and the level of autonomy. Conclusions. Proximity and anxiety (components of attachment) have a significant inverse relationship with the level of real self-determination in students. There are no significant connections between reliability (a component of attachment) and real self-determination in the sample under study. Emotional autonomy, cognitive autonomy, behavioral autonomy, and value autonomy have significant positive correlations with the level of real self-determination in students.

Abstract Objectives : In this cross-sectional study among 220 medical students we aimed to determine the nutritional knowledge and attitude of medical students through clinical training courses (externship and internship) of Tabriz University of Medical Sciences, Iran. A nutritional knowledge questionnaire included 51 questions was used to determine the correct, perceived and accuracy of knowledge of the participant in different aspects of nutrition sciences. Nutritional knowledge was calculated as percentage of correct responses. The nutrition attitude questionnaire included 30 questions. Both questionnaires were confirmed in terms of the validity and reliability for assessing nutritional knowledge and attitude in this sample of Iranian medical students. Results: The mean score of correct knowledge was not significantly different among externs and interns (68.20±7.50% and 67.87±6.04% respectively, p=0.729). Results showed that most of the participants (49.61% of externs and 57.14% of inters) had a poor nutritional knowledge, significantly varied by age (p=0.035). The mean attitude index of the subjects was not significantly different among externs and interns (106.37±13.66 and 108.16±13.35 out of 145 respectively, p=0.337). Most students (92.7%) had a very appropriate attitude toward nutrition, significantly varied by sex (p=0.010). These findings indicate that there are multiple deficiencies in nutrition knowledge of medical students.
