The Effectiveness of Mindfulness-Based Stress Reduction on Cognitive Flexibility and Sleep Quality in the Elderly Men

The present study aimed to determine the effectiveness of mindfulness-based stress reduction as one of the effective and new methods in improving cognitive flexibility and sleep quality in the elderly. It was a quasi-experimental study with pretest, posttest and control group design. The statistical population of the study included all elderly men in Dezful in 2018. The samples of this study consisted of 30 men elderlies (60-70 Ages) who were selected through available sampling and according to inclusion criteria. The experimental group received eight ninety-minute sessions during two months while the control group didn’t receive this intervention during conducting the study. The applied questionnaires in the study included [1] Pittsburgh Sleep Quality Index (PSQI) and Cognitive Flexibility Scale. Data were analyzed using univariate analysis of covariance. The findings showed that mindfulness-based stress reduction could significantly improve cognitive flexibility and sleep quality. based on the findings, it can be concluded that mindfulness-based stress reduction can be considered as an effective intervention to improve cognitive flexibility and sleep quality in the elderly men.

Enhancing Metacognitive Scaffolding and Comprehension Ability through Problem-Based Learning in an EFL Context

Successful reading necessitates the application of metacognitive reading strategies, which have been proven to be effective in enhancing comprehension in EFL contexts. This quasiexperimental study, thus, aimed to implement a problem-based learning method (PBL) in an EFL instructional setting to investigate its effect on EFL learners’ metacognitive reading strategies awareness and use and their comprehension ability. Two groups of students at the elementary level, one experimental (N = 40) and one control (N = 40) were selected. Their homogeneity in English proficiency was probed by Key English Test (KET). The experimental group received PBL and the control group followed the explicit lecture-based teaching method. The two groups completed pre- and posttest of metacognitive awareness of reading strategies inventory (MARSI) and reading comprehension. The findings based on univariate analysis of covariance indicated that the experimental group had high metacognitive reading strategies awareness and enhanced their comprehension ability to a high extent. Practitioners should pay special attention to the PBL method in EFL contexts if they want to enhance metacognitive strategies awareness and cultivate effective reading.

The Effectiveness of Compassion-Focused Therapy on Loneliness and Cognitive Flexibility in Elderly Men

The phenomenon of aging is the result of the natural course of time, which leads to physiological, psychological and social changes. Considering the accelerating growth of the aging population and the fact that the elderly suffers from reduced cognitive flexibility and feelings of loneliness due to old age and reduced abilities; Therefore, this study was performed to determine the effectiveness of compassion- focused therapy on loneliness and cognitive flexibility in elderly men. The research method was quasi-experimental with pretest-posttest design with a control group. The statistical population of the study was the elderly male in Ahvaz in 2020. The sample size consisted of 30 elderly men (60 to 70 years old) who were selected by convenience sampling method and according to the inclusion criteria. The experimental group received Therapeutic intervention in 8 weeks and 8 sessions of 90 minutes. The questionnaires used in this study included Dennis and Vanderwall Cognitive Flexibility Questionnaire and Russell Loneliness Questionnaire. Data were analyzed by univariate analysis of covariance. The results showed that there was a significant difference between the experimental and control groups in terms of loneliness and cognitive flexibility. In other words, compassion-focused therapy reduced loneliness and increased cognitive flexibility in the elderly. Consistent with the findings of the present study, compassion- focused therapy can be suggested as an effective method to reduce feelings of loneliness and increase cognitive flexibility in the elderly.

Improved Implant Positioning of Cephalomedullary Nail for Trochanteric Fractures Using the Stryker ADAPT Navigation System

Background:Tip-apex distance (TAD) of greater than 25 mm increases the risk of cephalomedullary nail (CMN) cutout for trochanteric hip fractures. The Stryker ADAPT navigation system provides intraoperative feedback to guide implant positioning. This study compares lag screw positioning using the ADAPT to conventional methods and investigates if the use of ADAPT impacts operating room efficiency. Methods: Retrospective review of 82 consecutive patients who underwent Stryker Gamma3 CMN for a peritrochanteric hip fracture. Study groups were assigned based on use of ADAPT navigation. Primary outcome was TAD. Secondary outcomes were lag screw position, operative time, and radiation dose. Univariate analysis of covariance was used to compare primary outcome measures, controlling for fracture classification. Results: 41 patients were assigned to each group. When comparing ADAPT and conventional groups mean TAD was 14.45±3.68 and 16.41±3.78 mm (p = 0.023). A higher portion of ADAPT nails (85.4% vs 63.4%, p = 0.024) were center- center within the femoral head compared to conventional methods. There were no significant differences with regards to operative time, fluoroscopy time, or radiation dose. Conclusion: ADAPT navigation provides intraoperative feedback to achieve improved lag screw positioning, leading to improved TAD. The overall improvement in TAD does not likely reach clinical significance. The system requires minimal setup in the operating room, does not impact workflow, and the user interface is straight forward.

A Longitudinal Exploration of Self-Reported Hearing Loss, Tinnitus, and Posttraumatic Stress Disorder Treatment Outcomes in Australian Veterans.

Tinnitus, hearing loss, and posttraumatic stress disorder (PTSD) are common conditions among veterans. Shared underlying symptoms, such as hypervigilance and heightened sense of threat, may interfere with talk-based psychological treatments. The aim was to investigate the prevalence and risk factors for self-reported tinnitus and hearing loss among Australian treatment-seeking veterans, as well as links with PTSD symptoms and quality of life (QOL) after treatment. Australian veterans participating in hospital-based PTSD treatment (n = 523) completed self-report measures of subjective hearing impairment, service-related factors, PTSD symptoms, and QOL at treatment intake and discharge, as well as 3- and 9-month follow-ups. Univariate analyses of covariance modeled symptom change over time. More than half of veterans on PTSD treatment self-reported doctor-diagnosed hearing loss or tinnitus, whereas 43% reported both. However, 75% reported subjective mild to moderate hearing impairment, and only 1% reported severe impairment. Service-related factors, such as longer length of service and exposure to explosions, were risk factors for having any hearing condition. After controlling for intake scores, there were no significant differences on PTSD or QOL outcomes over time between those with and without hearing conditions. Although self-reported tinnitus and hearing loss are prevalent among veterans, those with severe hearing impairments are unlikely to be represented in this context. There is a need for psychological treatments that are accessible to patients with severe hearing impairments, which should be examined routinely among military members accessing psychological treatments.

BACKGROUND Several factors affect the quality of sexual life. Vaginitis may impair the quality of life and lowers the self-esteem of a woman by distorting the mental image of her body. So far, no study has been done on the effectiveness of vaginitis treatment on the quality of sexual life. Therefore, considering the importance of quality of sexual life in family relationships, the present study was designed and conducted to determine the effects of vulvovaginitis treatment on women’s quality of sexual life. METHODS This experimental study was conducted on patients visiting Imam Sajjad Hospital in Shahriyar from 2017 to 2018. The Inclusion criteria in the study were as follows: having one of the vaginal infections, i.e., Candidiasis, Gardnerella, or mixed infection (both Candidiasis and Gardnerella) diagnosed by a specialist. The subjects filled in the quality of sexual life questionnaires before treatment and 2 months after the treatment. Data analysis was done by SPSS version 16 with paired t - test, univariate analysis of covariance (ANCOVA), analysis of variance, and multiple regression test. The P - value < 0.05 was considered significant. RESULTS In each of the three groups (candidiasis, Gardnerella, and mixed infection), the quality of sexual life differed before and after treatment, therefore the treatment improved the patients’ quality of life significantly. Mean and standard deviation of the quality of sexual life in Candidiasis group before and after treatments were 68.97 ± 19.59 and 75.82 ± 8.46 respectively; in Gardnerella group: 69.28 ± 19.04, 14.14 ± 72.15, and in the mixed group, they were 66.59 ± 18.91, 71.61 ± 13.47 respectively. In all three groups, the components of personal feelings and sexual life before and after treatment were different (P < 0.001). The regression test proved the effects of such variables as education, body mass index (BMI) and duration of infection on the quality of sexual life (P < 0.05), and the greatest effect was related to the duration of infection with a coefficient of - 0.342. CONCLUSIONS After treating the vaginal infections, these women's quality of sexual life improved. As a result, it can be concluded that the diagnosis and treatment of the disease can enhance the quality of sexual life. KEY WORDS Quality of Life, Quality of Sexual Life, Vaginitis, Treatment

The Effects of Transcranial Direct Current Stimulation on Depression, Anxiety, and Stress in Patients with Epilepsy: A Randomized Clinical Trial.

Background: Epilepsy is a chronic disorder that affects both sexes and causes some physiological and psychological disabilities. The present study aimed to examine the effects of transcranial direct current stimulation (tDCS) on the psychological profile of patients with epilepsy. Methods: The design of the present study was a randomized clinical trial with a pretest-posttest and a control group. The statistical population comprised patients with epilepsy, who were referred for treatment to a private health center in Urmia in 2019. The sample consisted of 30 patients with epilepsy selected via the convenience sampling method. Data collection was performed through the use of the Depression, Anxiety, and Stress Scale-21 (DASS-21) questionnaire. After the pretest, 15 subjects were randomly assigned to the intervention group, and 15 subjects were placed in the control group. The intervention was performed in 10 sessions, and the duration of stimulation was 20 minutes. The anode was placed in the F3 region (left hemisphere), the cathode in the F4 (right hemisphere), and the current intensity was 1.5 mA. After the intervention, the posttest was conducted for both groups, and the data were analyzed using a univariate covariance analysis in the SPSS software, version 23. A P value of less than 0.05 was considered statistically significant.Results: The results of the ANCOVA analyses revealed significant differences between the intervention and control groups. The tDCS group represented a significant decrease in the scales of depression, anxiety, and stress in the posttest in comparison with the pretest (P≤0.001).Conclusion: The results showed that tDCS could reduce depression, anxiety, and stress with the changes caused in the brain system.

Models of recovery: influence of psychosocial factors on substance use recovery

ABSTRACT Background The aim of this study is to analyze several psychosocial factors such as gender, legal or illegal substance use (alcohol and cocaine use), age, employment and social support to determine models of recovery. Methods quantitative research. Data from 2179 people receiving recovery treatment were extracted from EuropASI surveys, collected from the PH Nemos and Minerva databases. A two-factor multivariate and two univariate analysis of covariance were performed. The dependent variables were alcohol and years of cocaine use, the factors were gender and leisure social network, and the co-variables were age and number of people in the social network. Post-hoc tests were performed to analyze the differences among the five different leisure social network categories, and alcohol and cocaine use. Results Variables with the biggest influence on recovery are age, gender, and leisure social network. Two models of recovery with significant differences can be identified (Model 1/alcohol use, Model 2/cocaine use); for the alcohol model, individual leisure was the most important risk condition, while for the cocaine model individual leisure was the most important protective condition. Conclusions personal and social recovery adapted to the different characteristics of the people is essential to increase social integration and participation.

Exploring overweight and obesity beyond body mass index: A body composition analysis in people with and without patellofemoral pain

BackgroundWe compared body mass index (BMI), body fat, and skeletal muscle mass between (1) a mixed-sex nonathletic cohort of people with patellofemoral pain (PFP) and pain-free people, and (2) a nonathletic cohort of people with PFP and pain-free people subgrouped by sex (i.e., men and women with PFP vs. pain-free men and women). MethodsThis cross-sectional study included 114 people with PFP (71 women, 43 men) and 54 pain-free controls (32 women, 22 men). All participants attended a single testing session to assess body composition measures, which included BMI, percentage of body fat (%BFBioimpedance), and skeletal muscle mass (both assessed by bioelectrical impedance analysis), and percentage of body fat (%BFSkinfold) (assessed by skinfold caliper analysis). A one-way univariate analysis of covariance (age and physical activity levels as covariates) was used to compare body composition measures between groups (i.e., PFP vs. pain-free group; women with PFP vs. pain-free women; men with PFP vs. pain-free men). ResultsWomen with PFP presented significantly higher BMI, %BFBioimpedance, and %BFSkinfold, and lower skeletal muscle mass compared to pain-free women (p ≤ 0.04; effect size : ‒0.47 to 0.85). Men with PFP and men and women combined had no differences in BMI, %BFBioimpedance, %BFSkinfold, and skeletal muscle mass compared to their respective pain-free groups (p > 0.05). ConclusionOur findings indicate that BMI and body composition measures should be considered as part of the evaluation and management of people with PFP, especially in women, who have demonstrated higher BMI and body fat and lower skeletal muscle mass compared to pain-free controls. Future studies should not assess body composition measures in a mixed-sex population without distinguishing men participants from women participants.

Effects of Proprioceptive and Craniocervical Flexor Training on Static Balance in University Student Smartphone Users with Balance Impairment: A Randomized Controlled Trial.

PurposeUniversity student smartphone users adopt flexed neck postures during smartphone use, creating an increased compressive load on their neck structures. This study was conducted to compare the effects of proprioceptive and craniocervical flexor training with a control group on static balance in a group of university student smartphone users with balance impairment.MethodsA double-blinded, randomized controlled trial was conducted involving 42 university students (19.67±1.68 years old) with balance impairment. Participants were randomized into a proprioceptive training (ProT) group (n=14), a craniocervical flexor training (CCFT) group (n=14), and a control group (CG; n=14) for a 6-week intervention. The balance error scoring system (BESS), cervical joint position sense (CJPS), craniocervical flexion (CCF) test, and visual analog scale (VAS) for neck pain were evaluated using univariate analysis of covariance (ANCOVA).ResultsAfter 6 weeks of intervention, the ProT group showed significantly greater improvement of CJPS than the CG (p=0.000) and the CCFT group significantly improved of CCF test than CG (p=0.002). Findings, at 4 weeks after intervention, were (i) the ProT group had significantly more improvement in BESS than the CCFT group (p=0.014) and CG (p=0.003), (ii) the ProT group had significantly more improvement of CJPS than the CG (right and left rotate) (p=0.001, p=0.016, respectively) and CCFT group (right rotate) (p=0.004), (iii) the CCFT group had significantly more improvement of craniocervical flexor strength than CG (p=0.004), and (iv) the ProT group and CCFT group had significantly more decreased pain than CG (p=0.015, p=0.033, respectively). No adverse effects occurred during or after training in any group.ConclusionProT is important for regaining static balance and CJPS, while CCFT improved craniocervical flexor strength. Moreover, both ProT and CCFT can reduce neck pain. We recommend performing ProT to improve static balance, CJPS and to reduce neck pain in smartphone users with static balance impairment.Clinical Trail Registration NumberTCTR20190909003.

Anxiety and depression in women hospitalized due to high-risk pregnancy: An integrative quantitative and qualitative study

Literature has shown that hospitalized women with high-risk pregnancy tend to develop anxious and depressive symptoms. Research has used quantitative or qualitative methods. By integrating both quantitative and qualitative methods, this study aims to analyze: a) the level of depression, anxiety, and pregnancy-related anxiety in a group of women hospitalized with high-risk pregnancy (hospitalized high-risk) compared with a group of non-hospitalized women with low-risk pregnancy; b) the content of hospitalization-related emotions in a high-risk group. A cross-sectional study was conducted on 30 hospitalized high-risk pregnant women and 32 women with low-risk pregnancy. Participants completed the Edinburgh Postnatal Depression Scale, Hospital Anxiety and Depression Scale (Anxiety), and Pregnancy Related Anxiety Questionnaire. The hospitalized high-risk group also completed open-ended questions about emotions experienced during hospitalization. Univariate Analysis of Covariance showed that the hospitalized high-risk group reported higher general anxiety and depression than the low-risk pregnancy group. Low-risk group reported higher level of concerns about own appearance than high-risk group. Narratives showed that the anxious and depressive symptoms of hospitalized women are related to the loneliness of being away from family. Despite attempts to understand hospitalization, they express concerns about pregnancy. Psychological support for hospitalized pregnant women should be provided to facilitate the communication of emotions that leads women to elaborate the experience of hospitalization to better adapt and cope with the critical condition.

Age-Related Changes in Concentric and Eccentric Isokinetic Peak Torque of the Trunk Muscles in Healthy Older Versus Younger Men

This study investigated age-related changes in trunk muscle function in healthy men and the moderating effect of physical activity. Twelve older (67.3 ± 6.0years) and 12 younger (24.7 ± 3.1years) men performed isokinetic trunk flexion and extension tests across a range of angular velocities (15°/s-180°/s) and contractile modes (concentric and eccentric). For concentric trunk extension, mixed-effects analysis of covariance revealed a significant interaction between Angular velocity × Age group (p = .026) controlling for physical activity. Follow-up univariate analysis of covariance revealed that the younger group produced significantly greater peak torque for all concentric extension conditions. Eccentric trunk strength was somewhat preserved in the older group. Age-related changes in trunk strength were independent of physical activity. The normal loss of trunk muscle strength in older age is muscle- and contractile-mode specific. These findings provide guidance for effective intervention strategies to offset adverse health outcomes related to trunk strength loss in older adults.

White matter alterations in young children with prenatal alcohol exposure.

Prenatal alcohol exposure (PAE) can lead to cognitive, behavioural, and social-emotional challenges. Previous neuroimaging research has identified structural brain alterations in newborns, older children, adolescents, and adults with PAE; however, little is known about brain structure in young children. Extensive brain development occurs during early childhood; therefore, understanding the neurological profiles of young children with PAE is critical for early identification and effective intervention. We studied 54 children (5.21±1.11years; 27 males) with confirmed PAE (94% also had other prenatal exposures, 74% had adverse postnatal experiences) compared with 54 age- and sex-matched children without PAE. Children underwent diffusion tensor imaging between 2 and 7years of age. Mean fractional anisotropy (FA) and mean diffusivity (MD) were obtained for 10 major white matter tracts. Univariate analyses of covariance were used to test group differences (PAE vs. control) controlling for age and sex. The PAE group had higher FA in the genu of the corpus callosum and lower MD in the bilateral uncinate fasciculus. The PAE group also had lower tract volume in the corpus callosum, the bilateral inferior fronto-occipital fasciculi, and the right superior longitudinal fasciculus. Our findings align with studies of newborns with PAE reporting lower diffusivity, but contrast those in older populations with PAE, which consistently report lower FA and higher MD. Further research is needed to understand trajectories of white matter development and how our results of higher FA/lower MD in young children connect with lower FA/higher MD observed at older ages.

Do baseline cognitive status, participant specific characteristics and EDSS impact changes of cognitive performance following aerobic exercise intervention in multiple sclerosis?

PurposeCognitive impairment is a common symptom of multiple sclerosis (MS). Physical exercise represents a promising non-pharmacological therapy option, however, potential predictors for successful cognitive improvements mediated by exercise remain to be elucidated in order to optimize targeted exercise training regimens. One of the most promising exercise training regime in this context is high-intensity interval training (HIIT). Against this backdrop, this study i) analysed the effects of a three-week HIIT compared to moderate continuous exercise on cognitive performance and ii) investigated potential predictors for changes of cognitive performance following a three-week aerobic exercise intervention. MethodsDatasets of two randomized controlled trials (RCT) were pooled, resulting in a total sample size of n = 130 persons with MS (pwMS) who either performed HIIT or moderate intensity continuous (MCT) exercise 3–5x/ week for three weeks. Cognitive performance was assessed with the Brief International Cognitive Assessment for MS. I) Potential within (time) and interaction (time x group) effects for cognitive performance were investigated with univariate analyses of covariance (ANCOVA). II) Potential predictors for changes of cognitive performance were assessed by multiple linear regression models. ResultsANCOVA revealed significant time effects for all cognitive outcomes and a time x group interaction for verbal learning (p=.045), with HIIT inducing superior effects compared to moderate continuous exercise (MCT). Cognitive status (impaired/intact cognition) (p= .008) and exercise regime (HIIT/moderate continuous) (p=.040) influenced changes of verbal learning. Cognitive status (p=.006) and EDSS (p=.048) affected changes of visuospatial memory in pwMS. The models accounted for 5.4% and 7.7% of the variance. ConclusionCognitive status, exercise regime and EDSS potentially impact changes of specific cognitive domains following aerobic exercise. Further predictors for changes of cognitive performance following an aerobic exercise intervention need to be investigated as current results accounted only for a limited amount of variance. RCTs that investigate effects of physical exercise on cognitive performance should include only pwMS with impaired baseline cognitive performance. To better understand the impact of exercise on cognitive performance, it is furthermore recommendable to include cognitive assessments in clinical routine.

Extension of Marriage Benefit to Long-Distance Relationship: Comparative Evidence from East Asia

Background: Being married is related to better physical and mental health compared to being single or in an unmarried relationship. For those in long-distance relationship (LDR), there are mixed findings in psychological and physical health outcomes when compared to individuals in proximal relationship (PR). Objective: To explore the health differences between those in LDRs and PRs in a larger and non-Western sample with more health behaviors than had been previously assessed. Materials and Methods: The present study analyzed the data from the East Asian Social Survey (EASS) comparing health variables and health habits between LDR and PR participants. There were 7,145 respondents including 2,750 in LDR and 4,395 in PR. Physical and mental health were measured using SF-12 version 2, while, the frequency of smoking, drinking alcohol, and engaging in physical activity were used to assess health habits. Univariate analysis of covariance (ANCOVA) was used to control the confounding effect. Results: The results suggested that PR participants reported better overall mental health, while those in LDRs were healthier in terms of less alcohol use. The overall physical health did not differ across the groups. Moreover, the present study uncovered an unexpected number of LDR couples in China compared to the other countries assessed. Conclusion: The present study provided further understanding of the connection between LDR and health in a large sample across the countries.

Robotics Versus Navigation Versus Conventional Total Hip Arthroplasty: Does the Use of Technology Yield Superior Outcomes?

BackgroundThe use of technology such as navigation and robotic systems may improve the accuracy of component positioning in total hip arthroplasty (THA), but its impact on patient-reported outcome measures (PROMs) remains unclear. This study aims to elucidate the association between the use of intraoperative technology and PROMs in patients who underwent primary THA. MethodsWe retrospectively reviewed a consecutive series of patients who underwent primary THA between 2016 and 2020 and answered PROM questionnaires. Patients were separated into 3 groups depending on intraoperative technology utilization: computer-assisted navigation, robotic-assisted, or no technology (conventional) THA. Forgotten Joint Score-12 and Hip disability and Osteoarthritis Outcome Score, Joint Replacemen scores were collected at various time points. Demographic differences were assessed with chi-square and analysis of variance. Mean scores between groups were compared using univariate analysis of covariance, controlling for all significant demographic differences. ResultsOf the 1960 cases identified, 896 used navigation, 135 used robotics, and 929 used no technology. There were significant statistical differences in one-year Hip disability and Osteoarthritis Outcome Score, Joint Replacement scores (85.23 vs 85.95 vs 86.76, respectively; P = .014) and two-year Forgotten Joint Score-12 scores (64.72 vs 73.35 vs 74.63, respectively; P = .004) between the 3 groups. However, these differences did not exceed the mean clinically important differences. Length of stay was statistically longest for patients who underwent conventionally performed THA versus navigation and robotics (2.22 vs 1.46 vs 1.91, respectively; P < .001). Surgical time was significantly longer for cases performed using robotics versus navigation and conventionally (119.61 vs 90.35 vs 95.35, respectively; P < .001). ConclusionStatistical differences observed between all modalities are not likely to be clinically meaningful with regard to early patient-reported outcomes. Although intraoperative use of technology may improve the accuracy of implant placement, these modalities have not yet translated into improved early reported functional outcomes.

U.S. Physical Education Teacher Education Faculty Members’ Workplace Perceptions Across Gender and Institution Type

Purpose: To examine the workplace experience of physical education teacher educators while accounting for gender and institution type. Method: Participants included 286 U.S. faculty members (151 females and 135 males). Data were collected using an online survey that included measures of negative (i.e., marginalization, isolation, role stress, emotional exhaustion) and positive (i.e., perceived mattering, perceived organizational support) workplace experiences. Primary analyses began with a multivariate analysis of covariance followed up by univariate analyses of covariance to examine the differences in study variables based on gender and institution type. Results: Doctoral institution faculty members reported higher marginalization and lower perceived mattering and organizational support. Female faculty members reported higher role overload and emotional exhaustion. Discussion: Results highlight differences in the faculty experience across institution types as well as gender disparities. Recommendations are provided for improving the faculty experience as well as for future research in the area.

اثربخشی درمان شناختی مبتنی بر ذهن آگاهی بر کاهش شدت درد و اضطراب مرگ در بیماران دیالیزی: یک مطالعه راهنما

Background and Objective: Patients with renal failure are more prone to depression than others and have higher death anxiety. The aim of this study was to determine the effectiveness of mindfulness-based cognitive therapy on reducing pain intensity and death anxiety among patients undergoing dialysis. Materials and Methods: This study was semi-experimental and in the form of a pretest-posttest design with a control group. The statistical population of this study consisted of all patients who were referred to dialysis ward of Al-Jalil hospital in Aqqala city in the first quarter of 2019, among whom 22 patients were selected by convenience sampling method and randomly assigned to experimental and control groups. First, a pre-test was held. The experimental group then received mindfulness-based cognitive therapy for eight sessions of 90 minutes, and the control group did not receive any training. Then the post-test was held. Data collection tools were pain intensity and death anxiety questionnaires. Data were analyzed using univariate covariance analysis, and the above statistical analysis was performed using SPSS.22 software. The significance level of the tests was 0.05. Results: In the experimental group, the mean (SD) of death anxiety decreased from 10.0 (1.5) in the pre-test to 6.3 (1.1) in the post-test (P<0.001). Also, in the experimental group, the mean (SD) pain intensity decreased from 31.7 (7.8) in the pre-test to 22.9 (6.5) in the post-test (P<0.001). There was no significant difference between the mean (SD) of death anxiety scores and pain intensity in the control group in pre-test and post-test. Conclusion: The study showed that mindfulness-based cognitive therapy reduced pain intensity and death anxiety in dialysis patients.

Examining brain white matter after pediatric mild traumatic brain injury using neurite orientation dispersion and density imaging: An A-CAP study

BackgroundPediatric mild traumatic brain injury (mTBI) affects millions of children annually. Diffusion tensor imaging (DTI) is sensitive to axonal injuries and white matter microstructure and has been used to characterize the brain changes associated with mild traumatic brain injury (mTBI). Neurite orientation dispersion and density imaging (NODDI) is a diffusion model that can provide additional insight beyond traditional DTI metrics, but has not been examined in pediatric mTBI. The goal of this study was to employ DTI and NODDI to gain added insight into white matter alterations in children with mTBI compared to children with mild orthopedic injury (OI). MethodsChildren (mTBI n = 320, OI n = 176) aged 8–16.99 years (12.39 ± 2.32 years) were recruited from emergency departments at five hospitals across Canada and underwent 3 T MRI on average 11 days post-injury. DTI and NODDI metrics were calculated for seven major white matter tracts and compared between groups using univariate analysis of covariance controlling for age, sex, and scanner type. False discovery rate (FDR) was used to correct for multiple comparisons. ResultsUnivariate analysis revealed no significant group main effects or interactions in DTI or NODDI metrics. Fractional anisotropy and neurite density index in all tracts exhibited a significant positive association with age and mean diffusivity in all tracts exhibited a significant negative association with age in the whole sample. ConclusionsOverall, there were no significant differences between mTBI and OI groups in brain white matter microstructure from either DTI or NODDI in the seven tracts. This indicates that mTBI is associated with relatively minor white matter differences, if any, at the post-acute stage. Brain differences may evolve at later stages of injury, so longitudinal studies with long-term follow-up are needed.
