Status quo and predictors of Weibo users' attitudes toward lesbians and gay men in 31 provinces in the Chinese mainland: Analysis based on supervised machine learning and provincial panel data.

Introduction: Public attitudes toward consensual same-sex relations are crucial to lesbians' and gay men's rights and society's well-being, but research addressing this topic in China is limited. We comprehensively explored the current status and predictors of Weibo users' attitudes toward individuals who are lesbian or gay (IWLG) at the provincial level in the Chinese mainland. Methods: Natural language processing and machine learning techniques were incorporated to analyze 1,934,008 Weibo posts from January 1, 2010, to December 31, 2020, to evaluate Weibo users' expressed attitudes toward IWLG in 31 provinces in the Chinese mainland guided by the ABC Model of attitude. Results: Although the general attitudes, feelings, and support for the rights of Weibo users toward IWLG among different provinces were relatively positive, knowledge about IWLG was noticeably inaccurate. Economic development and educational level positively predicted certain aspects of attitudes at the provincial level. Conclusion: Weibo users from different provinces are generally supportive and accepting of people who are gay and the rights of the gay community. However, considerable misconceptions and inaccurate knowledge of IWLG surfaced in Weibo users' posts. Economic development and educational level were important predictors of specific attitudes toward IWLG at the provincial level. Increased efforts to address the unbalanced and insufficient development between different provinces could help reduce the public's prejudice, stigma, and discrimination toward IWLG. Policies that facilitate greater implementation of Comprehensive Sexuality Education sequentially and effectively are suggested as well.

The relaxation zone: Initial analysis of stress management services for university students.

Objective: We evaluated the Relaxation Zone (RZ), a room with "relaxation stations" designed to reduce stress in college students. Participants: Participants (N = 994) were enrolled during the 2019 calendar year. Most participants were female (62.8%), freshmen (59.3%), and African American (44.9%). Methods: Students visiting the RZ completed a brief pretest and posttest that measured self-reported stress. Results: Paired sample t-tests across class groups (e.g., freshman, sophomore) revealed a significant reduction in stress from pretest (Mpooled = 6.0) to posttest (Mpooled = 4.5), with medium to large effect sizes (Cohen's d ranging from 0.53 to 0.88) during their first visit. For students having at least two visits (N = 348), an exploratory dose-response analysis demonstrated that an optimal dose of self-guided relaxation ranged from two to eight visits. Conclusions: These findings provide initial evidence that programs like the RZ can reduce student stress within a few visits.

The Immediate Effect of Sinapis nigra and Zingiber officinale as Thermogenic Substances during Footbaths: A Randomized Controlled Crossover Trial.

OBJECTIVE: Warm footbaths infused with Sinapis nigra (mustard, or MU) or Zingiber officinale (ginger, or GI) are used for various thermoregulatory conditions, but little is known about how they are perceived by individuals, both short- and long-term. We analyzed the immediate and long-term effects of MU and GI on warmth and stimulus perception in healthy adults. METHODS: Seventeen individuals (mean age 22.1±2.4 years; 11 female) received three footbaths (mean temperature was 40 ± 0.2°C, administered between 1:30 and 6:30 p.m.) in a randomized order with a crossover design: 1. with warm water only (WA), 2. with warm water and MU, and 3. with warm water and GI. Warmth and stimulus perception at the feet were assessed at the 1st, 5th, 10th, 15th, and 20th minute of the footbaths, in the late evening (EVE), and the following morning (MG). We further assessed well-being (at EVE and MG) and sleep quality (at MG). The primary outcome measure was the warmth perception at the feet at the 10th minute of the footbath. RESULTS: At the 10th minute of the footbath, warmth perception at the feet was significantly higher with MU and GI compared to WA. The immediate thermogenic effects pointed to a quick increase in warmth and stimulus perception with MU, a slower increase with GI, and a gradual decrease with WA. Regarding the long-term effects, warmth and stimulus perception were still higher after GI compared to WA at EVE and MG. No differences were seen for general well-being and sleep quality. CONCLUSION: Thermogenic substances can significantly alter the dynamics of warmth and stimulus perception when added to footbaths. The different profiles in the application of GI and MU could be relevant for a more differentiated and specific use of both substances in different therapeutic indications.

Acceptance and commitment therapy for high frequency episodic migraine without aura: Findings from a randomized pilot investigation.

OBJECTIVE: We compared the incremental effects of adding acceptance and commitment therapy (ACT) to pharmacological treatment as usual (TAU) in a sample of patients with high frequency episodic migraine without aura (HFEM), assessing impact on a spectrum of measures across multiple domains. BACKGROUND: Patients with HFEM are at risk of developing chronic migraine and medication overuse headache. ACT has been shown to be effective for the treatment of various chronic pain conditions, but little attention has been given to its therapeutic value in the management of recurring headaches. METHODS: In this single-blind (masking for outcome assessor), open-label, randomized clinical trial, 35 patients with HFEM, with a monthly headache frequency ranging from 9 to 14 days, were recruited at the headache center of C. Besta Neurological Institute and randomized to either TAU (patient education and pharmacological prophylaxis; n = 17) or TAU + ACT (n = 18). Patients assigned to the combined treatment arm additionally received six 90-min weekly group sessions of ACT therapy and two supplementary "booster" sessions. All patients were on a stable course of prophylactic medication in the 3 months prior to initiating either treatment. Monthly headache frequency served as the primary outcome measure, with all other data collected being considered as secondary measures (medication intake, disability, headache impact, anxiety and depression, catastrophizing, allodynia, cognitive inflexibility, pain acceptance, mindful attention and awareness). RESULTS: A total of 35 patients were enrolled: 17 randomized to TAU, of whom three dropped out, and 18 to TAU + ACT (no dropouts in this group). Headache frequency and medication intake decreased in both groups over 12 months, with patients in the TAU + ACT group showing statistically significant reduction earlier, that is, by month 3. Headache frequency was reduced by 3.3 days (95% CI: 1.4 to 5.2) among those randomized to ACT + TAU, whereas it increased by 0.7 days (95% CI: -2.7 to 1.3) among those randomized to TAU only (p = 0.007, partial η2  = 0.21), the difference being 4 days (95% CI: 1.2 to 6.8). Medication intake was reduced by 4.1 intakes (95% CI: 2.0 to 6.3) among those randomized to ACT + TAU and by 0.4 intakes (95% CI: -1.8 to 2.5) among those randomized to TAU only (p = 0.016; partial η2  = 0.17), the difference being 3.8 intakes (95% CI: 0.7 to 6.8). At 6 and 12 months, the variations were not different between the two groups for headache frequency and medication intake. The opposite was found for measures of headache impact and pain acceptance, where the differences over time favored patients allocated to TAU. Both groups improved with regard to measures of disability, anxiety and depression, catastrophizing, and cognitive inflexibility, whereas measures of allodynia and pain acceptance were stable over time. CONCLUSIONS: Our preliminary findings indicate that supplementing TAU with ACT can enhance the main clinical outcomes, namely headache frequency and medication intake of patients with HFEM.

Psychophysiology during exposure to trauma memories: Comparative effects of virtual reality and imaginal exposure for posttraumatic stress disorder.

BACKGROUND: This investigation involved an in-depth examination of psychophysiological responses during exposure to the trauma memory across 10 sessions among active duty soldiers with combat-related posttraumatic stress disorder (PTSD) treated by Prolonged Exposure (PE) or Virtual Reality Exposure (VRE). We compared psychophysiological changes, session-by-session, between VRE and traditional imaginal exposure. METHODS: Heart rate (HR), galvanic skin response (GSR), and peripheral skin temperature were collected every 5 min during exposure sessions with 61 combat veterans of Iraq/Afghanistan and compared to the PTSD Checklist (PCL-C) and Clinician-Administered PTSD Scale (CAPS) outcomes using multilevel modeling. RESULTS: Over the course of treatment, participants in the PE group had higher HR arousal compared to participants in the VRE group. With reference to GSR, in earlier sessions, participants demonstrated a within-session increase, whereas, in later sessions, participants showed a within-session habituation response. A significant interaction was found for GSR and treatment assignment for within-session change, within-person effect, predicting CAPS (d = 0.70) and PCL-C (d = 0.66) outcomes. CONCLUSION: Overall, these findings suggest that exposure to traumatic memories activates arousal across sessions, with GSR being most associated with reductions in PTSD symptoms for participants in the PE group.

Development and Validation of the Chinese Version of Short-Form of Interpersonal Sensitivity Measure (IPSM).

This study was conducted to develop a short form of the Interpersonal Sensitivity Measure (IPSM), translated into Chinese. A total of 1237 Chinese undergraduates, divided into four groups, participated during various phases of scale development. Exploratory factor analysis supported a five-factor structure of the IPSM-C among Chinese undergraduates, which is in accordance with the original model established by Boyce and Parker that contained 36 items. We next developed a 15-item short form of the IPSM (IPSM-CS) whose structural validity was comparable to the full form. All IPSM-CS sub-scales, as well as the total scale, showed good internal consistency, test-retest reliability and criterion-related validity. The present results indicate that the IPSM-CS may be a useful and reliable alternative to the original IPSM for individuals fluent in Chinese.

The Buteyko breathing technique in children with asthma: a randomized controlled pilot study.

BACKGROUND: Evidence supports the Buteyko breathing technique (BBT) as reducing medication and improving control and quality of life in adults with asthma, but having minimal impact on spirometry. For children with asthma, evidence addressing the utility of BBT is sparse. We evaluated the effectiveness of BBT in managing various aspects of asthma in children. METHODS: Thirty-two children with partly controlled asthma (age 6-15 years, 66% male) were randomized to either Treatment as Usual (TAU) or TAU combined with Buteyko training (Buteyko group, BG). Children in the BG received an intensive five-day training followed by three months of home practice. Primary outcome was bronchodilator reduction. Secondary outcomes were changes in physiological parameters FEV1_AR (at rest), FEV1_ER (after ergometry), FEV1_BR (after bronchospasmolysis), corticosteroid use, FeNO, SpO2, breath-hold test and questionnaire data [Asthma Control Questionnaire and Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)]. All measures were collected at Baseline and a three-month follow-up. RESULTS: For the primary outcome, no significant between-group difference was found. Regarding the secondary outcomes, children receiving treatment augmented with BBT revealed significantly greater improvement at the follow-up than those receiving TAU for FEV1_AR (p = .04, d=-0.50), FEV1_ER (p = .02, d=-0.52), and the emotional function subscale of the PACQLQ (p < .01, d = 1.03). No between-group differences were found for the remaining secondary measures of outcome. CONCLUSIONS: Our preliminary findings suggest that the addition of BBT to treatment as usual for children with asthma enhances outcomes with respect to spirometry and parental emotional function but does not lead to reductions in medication, at least over the short term.

Changes in physiological reactivity in response to the trauma memory during prolonged exposure and virtual reality exposure therapy for posttraumatic stress disorder.

OBJECTIVE: A key symptom of posttraumatic stress disorder (PTSD) is hyperreactivity to trauma-relevant stimuli. Though physiological arousal is reliably elevated in PTSD, the question remains whether this arousal responds to treatment. Virtual reality (VR) has been posited to increase emotional engagement during prolonged exposure therapy (PE) for PTSD by augmenting imaginal exposures with trauma-relevant sensory information. However, the comparative effects of VR exposure therapy (VRE) have received limited empirical inquiry. METHOD: Ninety active-duty soldiers with combat-related PTSD participating in a randomized-controlled trial to receive PE, VRE, or a waitlist-control (WL) condition had their physiological reactivity, indexed by galvanic skin response (GSR), to their trauma memories assessed at pre-, mid-, and posttreatment. RESULTS: Although both VRE and PE conditions showed reduced GSR reactivity to trauma memories from pre- to posttreatment, only the VRE group differed significantly from WL. Across the sample, reductions in GSR were significantly correlated with reductions in self-reported PTSD and anxiety symptoms. CONCLUSIONS: This was the first study comparing effects of VRE and PE on psychophysiological variables. Given previous research finding limited differences between VRE and PE in PTSD symptom reduction, these findings lend support to the rationale for including VR in exposure therapy protocols while raising important questions about the potential benefits of VRE.

Mediating effects of rumination and bedtime procrastination on the relationship between Internet addiction and poor sleep quality.

BACKGROUND AND AIMS: Numerous studies have shown that people who have Internet addiction (IA) are more likely to experience poor sleep quality than people who do not. However, few studies have explored mechanisms underlying the relation between IA and poor sleep quality. As a first attempt to address this knowledge gap, a cross-sectional design was applied, and structural equation modeling was used to explore the direct relationship between IA and poor sleep quality, as well as the potential mediating roles of rumination and bedtime procrastination. METHODS: A convenience sample, consisting of 1,104 Chinese University students (696 females or 63%), completed an online survey that included the following measures: Young's 8-item Internet Addiction Diagnosis Questionnaire, the Pittsburgh Sleep Quality Index, the Ruminative Responses Scale, and the Bedtime Procrastination Scale. RESULTS: While the direct path between IA and poor sleep quality was not found to be significant, rumination and bedtime procrastination were each shown to separately mediate the predictive effect of IA on poor sleep quality. However, the greatest level of support was found for the sequential mediating effects of rumination and bedtime procrastination between IA and poor sleep quality. CONCLUSION: While rumination and bedtime procrastination were both shown to be important independent mediators for the relation between IA and poor sleep quality, their combined effect was as great as either alone.

A randomized pilot program to reduce opioid use following dental surgery and increase safe medication return.

Research indicates that increased cumulative exposure (duration of administration and strength of dose) is associated with long-term opioid use. Because dentists represent some of the highest opioid prescribing medical professionals in the US, dental practices offer a critical site for intervention. The current study used a randomized clinical trial design to examine the efficacy of an opioid misuse prevention program (OMPP), presented as a brief intervention immediately prior to dental extraction surgery. The OMPP provided educational counseling about risks and appropriate use of opioid medication, as well as 28 tablets of ibuprofen (200 mg) and 28 tablets of acetaminophen (500 mg) for weaning off opioid medication. This was compared with a Treatment as Usual (TAU) control condition. Participants were individuals presenting for surgery who were eligible for opioid medication (N = 76). Follow up assessment was conducted at 1 week following surgery, with 4 individuals refusing follow up or not prescribed opioid. Intent to treat analysis indicated a non-significant treatment group effect (N = 72, Beta = 0.16, p = .0835), such that the OMPP group self-reported less opioid use (in morphine milligram equivalents, MMEs) than the TAU group (37.94 vs. 47.79, effect size d = 0.42). Sensitivity analysis, excluding individuals with complications following surgery (n = 6) indicated a significant treatment group effect (N = 66, Beta = 0.24, p = .0259), such that the OMPP group self-reported significantly less MMEs than the TAU group (29.74 vs. 43.59, effect size d = 0.56). Results indicate that a 10-minute intervention and provision of non-narcotic pain medications may reduce the amount of self-administered opioid medication following dental surgery.

Behavioral Interventions for Migraine.

Biobehavioral interventions for migraine incorporate both physiologic and psychological factors. This article details treatments for migraine management and prevention, ranging from traditional to newly emerging interventions. Similarly, this article reviews key person-related factors that may affect migraine prevalence and management. Aspects related to patient-physician relationships and communication are also reviewed. Research involving childhood and adolescent migraine is reviewed, and special considerations regarding this population are summarized. Clinical trials and other studies have provided evidence that these behavioral interventions, when combined with pharmacotherapy, show a marked improvement in primary treatment outcomes, such as a decrease in headache frequency and duration.

Adverse childhood experiences predict opioid relapse during treatment among rural adults.

Adverse childhood experiences (ACE) are a public health concern and strong predictor of substance abuse, but no studies to date have explored the association between ACE and opioid relapse during medication-assisted treatment. Using an observational design, we examined this relationship using archived medical records of 87 patients who attended opioid use disorder treatment (buprenorphine-naloxone and group counseling) at a rural medical clinic. All variables were collected from medical files. ACE scores were derived from a 10-item screening questionnaire administered at intake, a regular procedure for this clinic. The primary outcome was opioid relapse observed at each visit, as indicated by self-reported opioid use, positive urine drug screen for opioids, or prescription drug database results for opioid acquisition. The sample was 100% Caucasian and 75% male. A total of 2052 visit observations from the 87 patients were extracted from the medical records. Patients had an average of 23.6 (SD = 22) treatment visits. Opioid relapse occurred in 54% of patients. Results indicated that for every unit increase in ACE score, there was an increase of 17% in the odds of relapse (95% CI: 1.05-1.30, p = .005). Additionally, each treatment visit was associated with a 2% reduction in the odds of opioid relapse (95% CI: 0.97-0.99, p = .008). We conclude that ACE may increase the risk for poor response to buprenorphine-naloxone treatment due to high rates of opioid relapse during the first treatment visits. However, consistent adherence to treatment is likely to reduce the odds of opioid relapse.

Behavioral and psychological aspects of cluster headache: an overview.

This paper overviews available literature addressing behavioral and psychological aspects of cluster headache. Behavioral correlates of sleep and drug use are explored, as are the psychological correlates pertaining to psychopathology and cognitive functioning. We conclude with a review of the few investigations addressing adjunctive behavioral treatments for cluster headache, and provide suggestions for possible ways to enhance effects of behavioral interventions for this painful and difficult to treat headache disorder.

A prospective pilot study of the effect on catecholamines of mindfulness training vs pharmacological prophylaxis in patients with chronic migraine and medication overuse headache.

AIM: To address whether, in patients with chronic migraine and medication overuse headache, mindfulness-based treatment is associated with changes in plasma levels of catecholamines and elusive amines that are similar to those observed in patients undergoing pharmacological prophylaxis. METHODS: In this non-randomized, clinic-based effectiveness study, patients aged 18-65, with a history of chronic migraine ≥ 10 years and overuse of triptans or non-steroidal anti-inflammatory drugs ≥ 5 years, were enrolled. Upon completion of a structured withdrawal program, patients received either pharmacological prophylaxis or six weekly sessions of mindfulness-based treatment and were followed for 12 months. Daily headache diaries were used to record headache frequency and medication intake; catecholamines (noradrenaline, epinephrine and dopamine) and levels of elusive amines were assayed from poor platelet plasma. RESULTS: Complete follow-up data were available for 15 patients in the pharmacological prophylaxis-group (14 females, average age 44.1) and 14 in the mindfulness treatment-group (all females, average age 46.4), and all variables were comparable between groups at baseline. At 12 months, significant improvement ( p < .001) was found in the pharmacological prophylaxis group for headache frequency and medication intake (by 51% and 48.7%, respectively), noradrenaline, epinephrine and dopamine (by 98.7%, 120.8% and 501.9%, respectively); patients in the mindfulness treatment-group performed similarly. For elusive amines, no longitudinal changes were found. CONCLUSIONS: The similar improvement trends observed in the two groups of patients further support the utility of mindfulness-based treatment in migraine care, and reinforce the hypothesis that alteration and normalization of tyrosine metabolism are implicated in migraine chronification and in remission of chronic migraine.

Non-pharmacological Approaches for Headaches in Young Age: An Updated Review.

Headache disorders are common in children and adolescents. Most of the studies on non-pharmacological treatments have however been carried out on adults. In this review we provide information on recent studies examining non-pharmacological approaches for managing headache in children and adolescents. Our search of SCOPUS for primary studies conducted between January 2010 and July 2018 uncovered 11 controlled studies, mostly addressing behavioral approaches, in which a total of 613 patients with a diagnosis of primary headache, and average age 10.2-15.7 years (30-89% females) were recruited. Non-pharmacological treatments were shown to produce sizeable effects on the classical primary endpoint, i.e., headache frequency, with reductions from baseline ranging between 34 and 78%. Among commonly reported secondary endpoints, particularly disability, quality of life, depression and anxiety, marked improvements were noted as well. Taken as a whole, our findings suggest that non-pharmacological treatments constitute a valid option for the prevention of primary headaches in young age. Future research with higher-quality studies is needed. Particular attention needs to be given to studies that randomize patients to condition, blind researchers in charge of evaluating treatment outcomes, routinely include headache frequency as the primary endpoint, include adequate-length follow-up, address changes in biomarkers of disease and other possible mediators of outcome, and that employ predictive models to enhance the level of evidence for these approaches.

Inkjet Printed Parallel Plate Capacitors Using PVP Polymer Dielectric Ink on Flexible Polyimide Substrates.

Inkjet printing (IJP) is an exciting new additive manufacturing technology that promises monolithic electronic circuit fabrication of $\mu \mathrm{m}$ thin low-cost large-area electronic low-cost body-worn flexible sensors. In this work, we demonstrate inkjet printed multilayer metal-dielectric-metal capacitors on flexible polyimide (PI) substrate by formulating a custom dielectric ink based on Poly 4-vinylphenol (PVP). Silver nanoparticle ink was used for printing theconductive parallel metal plates. We also demonstrate control over the capacitance values by varying the design parameters and succeeded in printing capacitors in the range 8.8 pF to 467 pF, with excellent repeatability on flexible PI substrates. A functional LC circuit using these printed capacitors has been designed and demonstrated to have a resonance frequency of 24.3 MHz. These results are a vital step forward towards monolithic printing of flexible electronic circuits using IJP technique formany applications such as body-worn sensors.

Behavioral Approaches for Primary Headaches: Recent Advances.

BACKGROUND: Behavioral treatments in the management of primary headache disorders in adults and children are increasingly being recognized as effective; however, the level and durability of their effectiveness is still a matter of debate. This review aims to provide more updated information on the effects of behavioral therapies in adults and adolescents with primary headache disorders, with a special focus on new and emerging behavioral treatments. METHODS: We searched SCOPUS for peer-reviewed papers that reported randomized controlled trial or observational studies addressing behavioral treatment for headache disorders published in the period January 2010 to October 2017. RESULTS: A total of 22 publications, in which 2110 participants were recruited, were included in the review. Most of the studies referred to cognitive behavioral therapies, and a reduction of headache frequency higher than 35% was generally reported irrespective of the approach. In addition, valuable impact disability and quality of life was observed, as well as improvements in depression, anxiety, self-efficacy, and intake of medications. CONCLUSIONS: Behavioral approaches are effective and less prone to produce side or harmful effects, which makes them a valid option particularly for women who are pregnant or nursing, people with other chronic conditions requiring pharmacological treatments putting them at risk for drug-drug interactions, and children.
