Contralesional Cathodal Transcranial Direct Current Stimulation Does Not Enhance Upper Limb Function in Subacute Stroke: A Pilot Randomized Clinical Trial.

Transcranial direct current stimulation (tDCS) has the potential to improve upper limb motor outcomes after stroke. According to the assumption of interhemispheric inhibition, excessive inhibition from the motor cortex of the unaffected hemisphere to the motor cortex of the affected hemisphere may worsen upper limb motor recovery after stroke. We evaluated the effects of active cathodal tDCS of the primary motor cortex of the unaffected hemisphere (ctDCSM1UH) compared to sham, in subjects within 72 hours to 6 weeks post ischemic stroke. Cathodal tDCS was intended to inhibit the motor cortex of the unaffected hemisphere and hence decrease the inhibition from the unaffected to the affected hemisphere and enhance motor recovery. We hypothesized that motor recovery would be greater in the active than in the sham group. In addition, greater motor recovery in the active group might be associated with bigger improvements in measures in activity and participation in the active than in the sham group. We also explored, for the first time, changes in cognition and sleep after ctDCSM1UH. Thirty subjects were randomized to six sessions of either active or sham ctDCSM1UH as add-on interventions to rehabilitation. The NIH Stroke Scale (NIHSS), Fugl-Meyer Assessment of Motor Recovery after Stroke (FMA), Barthel Index (BI), Stroke Impact Scale (SIS), and Montreal Cognitive Assessment (MoCA) were assessed before, after treatment, and three months later. In the intent-to-treat (ITT) analysis, there were significant GROUP∗TIME interactions reflecting stronger gains in the sham group for scores in NIHSS, FMA, BI, MoCA, and four SIS domains. At three months post intervention, the sham group improved significantly compared to posttreatment in FMA, NIHSS, BI, and three SIS domains while no significant changes occurred in the active group. Also at three months, NIHSS improved significantly in the sham group and worsened significantly in the active group. FMA scores at baseline were higher in the active than in the sham group. After adjustment of analysis according to baseline scores, the between-group differences in FMA changes were no longer statistically significant. Finally, none of the between-group differences in changes in outcomes after treatment were considered clinically relevant. In conclusion, active CtDCSM1UH did not have beneficial effects, compared to sham. These results were consistent with other studies that applied comparable tDCS intensities/current densities or treated subjects with severe upper limb motor impairments during the first weeks post stroke. Dose-finding studies early after stroke are necessary before planning larger clinical trials.

Religious Affiliations Influence Health-Related and General Decision Making: A Brazilian Nationwide Survey.

Approximately 90% of the world's population is involved in some spiritual/religious practice, and this dimension has a relevant role in life. Many studies demonstrate the associations between spirituality/religiosity (S/R), and physical, mental, and social health. Systematic reviews have indicated positive associations; however, the mechanisms behind religious coping are not fully understood. The present study aimed to examine the role of religious affiliation in general (ordinary) and health-related decisions. A nationwide, population-based, cross-sectional study was conducted in Brazil using a self-administered online survey. How much religious affiliation influences decision making was investigated. A total of 1133 participants were included, who were classified as Catholics (43.9%), Evangelicals (18.7%), spiritualists (12.8%), non-religious (11.9%), and others (12.7%). Most participants (66.5%) believed that their religious affiliations had moderate to high influences on their decisions. Participants rated the influence as high in marriage (62.7%), in donations (60.1%), in volunteering (55%), in friendships (53.9%), and in work (50.5%). Concerning health-related decisions, the influence was rated as high in drug use (45.2%), in accepting medical recommendations (45%), and in smoking (43.2%). The influence of religious affiliation on general decision making was significantly correlated for dietary restrictions (r = 0.462), alcohol consumption (r = 0.458), drug use (r = 0.441), tobacco consumption (r = 0.456), and refusal of medical recommendations (r = 0.314). Improving the understanding of how a patient's beliefs, practices, and experiences affect their health may help healthcare practitioners to take into account religious considerations, not only regarding influences on habits but also regarding adherence to medical treatment advice.

Lasmiditan efficacy in migraine attacks with mild vs. moderate or severe pain.

OBJECTIVE: To evaluate the efficacy of lasmiditan (LTN) in treating migraine attacks of mild vs. moderate or severe pain intensity. METHODS: Pooled data from two single-attack, placebo-controlled studies (SAMURAI [NCT02439320] and SPARTAN [NCT02605174]), and a prospective, randomized, open-label study (GLADIATOR [NCT02565186]) were assessed. Efficacy measures included the proportion of attacks with 2-h pain freedom (PF), 2-h most bothersome symptom (MBS) freedom, and 24-h sustained pain freedom (SPF). Fisher's exact test was used to compare the proportion of PF, SPF, or MBS freedom outcomes among attacks treated at mild, moderate, or severe pain. RESULTS: In SAMURAI and SPARTAN, most treated attacks were of moderate (N = 2768) or severe (N = 1147) intensity, compared to mild (N = 65). Numerically greater 2-h PF and 24-h SPF response rates were observed in attacks treated at mild compared to moderate or severe pain. Analysis of GLADIATOR data included 273 (1.5%), 11,644 (65.1%), and 5948 (33.3%) attacks treated when pain was mild, moderate, and severe, respectively. In general, a significantly greater proportion of attacks treated at mild pain achieved 2-h PF and MBS freedom, as well as 24-h SPF. The incidence of treatment-emergent adverse events in LTN treatment groups were similar regardless of baseline head pain intensity. CONCLUSIONS: Data from two placebo-controlled, single-attack trials, and an open-label study including treatment of multiple attacks, suggested a tendency to relatively better efficacy outcomes when LTN treatment was initiated at mild vs. moderate to severe pain. Further research is needed to better understand the relationship of lasmiditan outcomes to the time of administration in the course of a migraine attack.

Patterns of religiosity and spirituality of psychiatrists in Brazil and the implications for clinical practice: a latent profile analysis.

BACKGROUND: Although there is consensus, in psychiatry, over the inclusion of religious and spiritual aspects when evaluating and treating the patient, investigation of these dimensions is rare. There is evidence as to the relationship between psychiatrists' religious/spiritual beliefs and their willingness to discuss a patient's religion and spirituality (R/S). Due to the lack of information about how psychiatrists in Brazil deal with R/S in patient care, the aim of the present study is to analyze the religious/spiritual profile of these professionals and to ascertain its influence on attitudes and behavior in clinical practice. METHODS: Five hundred and ninety-two psychiatrists from Brazil answered a questionnaire about R/S in clinical practice. The latent profile analysis was used to search for differences of religious/spiritual profiles. The ANOVA and Pearson's chi-square tests were employed to identify any correlation between clinical opinion and behaviors according to the different profiles. RESULTS: Two religious/spiritual profiles were identified (entropy value > 0,96): the so called "less religious" group (n = 245), comprised predominantly by men, professionally more experienced, with a higher level of academic education (Master or PhD degrees) and were the ones who least enquired about their patients' R/S; and the "more religious" psychiatrists (n = 347) those who had higher consideration for R/S on health, and who more often addressed R/S with their patients and therefore usually ascribed importance to include R/S in their professional training. CONCLUSION: The latent profile analysis produced two distinct classes between the Brazilian psychiatrists according to their R/S views: the more religious professionals, who investigate the patient's R/S in a more detailed manner, and the less religious, who tend to disregard this aspect.

How psychiatrists think about religious and spiritual beliefs in clinical practice: findings from a university hospital in São Paulo, Brazil

Objective: To examine the relationship between psychiatrists' religious/spiritual beliefs and their attitudes regarding religion and spirituality in clinical practice. Methods: A cross-sectional survey of religion/spirituality (R/S) in clinical practice was conducted with 121 psychiatrists from the largest academic hospital complex in Brazil. Results: When asked about their R/S beliefs, participants were more likely to consider themselves as spiritual rather than religious. A total of 64.2% considered their religious beliefs to influence their clinical practice and 50% reported that they frequently enquired about their patients' R/S. The most common barriers to approaching patients' religiosity were: lack of time (27.4%), fear of exceeding the role of the doctor (25%), and lack of training (19.1%). Those who were less religious or spiritual were also less likely to find difficulties in addressing a patient's R/S. Conclusion: Differences in psychiatrists' religious and spiritual beliefs are associated with different attitudes concerning their approach to R/S. The results suggest that medical practice may lead to a religious conflict among devout psychiatrists, making them question their faith. Training might be of importance for handling R/S in clinical practice and for raising awareness about potential evaluative biases in the assessment of patients' religiosity.

Optimism, Pessimism, and Migraine: A Cross-Sectional, Population-Based Study.

BACKGROUND: Optimism and pessimism are related to several mental health and brain disorders, are significant predictors of physical and psychological health outcomes, and implicated as psychosocial determinants of the pain experience. Despite this promising evidence, limited information is available on optimism and pessimism in headache disorders. OBJECTIVE: To evaluate the influence of optimism and pessimism in meeting criteria for migraine and related disability in a population-based sample. METHODS: This is an observational, cross-sectional study. The sample population was selected through a stratified, multi-stage area probability sample of households, as used by the last Brazilian Census. A validated questionnaire eliciting data on demographics, headache features, migraine-related disability, depression (PHQ-9), anxiety (GAD-7), optimism, and pessimism (life orientation test - revised) was administered to people with migraine and headache-free control participants from the general population in São Paulo, Brazil via trained interviewers. Six hundred individuals were contacted. The odds for having migraine/no headache diagnosis were calculated by binary logistic regression, and ordinal regression was performed to check associations between migraine-related disability and optimism. RESULTS: A total of 302 individuals (mean ± SD age: 39.7 ± 12.7; BMI: 26.5 ± 5.9) met inclusion criteria and were included, 140 controls (with no history of headache disorders) and 162 people meeting criteria for migraine (29 with chronic migraine, that is, 15 or more headache days/month). People with migraine were less optimistic and more pessimistic than controls, and endorsed higher levels of anxious and depressive symptoms. Pessimism (OR 95% CI = 1.16 [1.05-1.28], P = .005) and anxiety (OR 95% CI = 1.19 [1.10-1.29], P < .001) were predictors of meeting criteria for migraine, while optimism (ß 95% CI = -0.915 [-1.643, -0.188], P = .01) was inversely associated with migraine-related disability. CONCLUSIONS: Optimism and pessimism are associated with migraine and migraine-related disability. These concepts should be further explored in people with migraine with regard to their potential influences on clinical research outcomes and treatments.

A preliminary survey on the religious profile of Brazilian psychiatrists and their approach to patients' religiosity in clinical practice.

BACKGROUND: Although there is evidence of a relationship between religion/spirituality and mental health, it remains unclear how Brazilian psychiatrists deal with the religion/spirituality of their patients. AIMS: To explore whether Brazilian psychiatrists enquire about religion/spirituality in their practice and whether their own beliefs influence their work. METHOD: Four hundred and eighty-four Brazilian psychiatrists completed a cross-sectional survey on religion/spirituality and clinical practice. RESULTS: Most psychiatrists had a religious affiliation (67.4%) but more than half of the 484 participants (55.5%) did not usually enquire about patients' religion/spirituality. The most common reasons for not assessing patients' religion/spirituality were 'being afraid of exceeding the role of a doctor' (30.2%) and 'lack of training' (22.3%). CONCLUSIONS: Very religious/spiritual psychiatrists were the most likely to ask about their patients' religion/spirituality. Training in how to deal with a patient's religiosity might help psychiatrists to develop better patient rapport and may contribute to the patient's quicker recovery. DECLARATION OF INTEREST: None.

Spiritual Treatment for Depression in Brazil: An Experience From Spiritism.

BACKGROUND: Spiritism has been strongly connected with mental health in Brazil. However, there is a lack of descriptions of spiritual treatment provided by thousands of Brazilian Spiritist centers. The present study aims to describe the spiritual care for depression provided by one large Spiritist center in São Paulo, Brazil. METHODS: This is a descriptive study carried out in 2012 at "São Paulo Spiritist Federation." Authors visited the "spiritual intervention sections," observed the therapies provided, listened to the "spirits' communication," and interviewed two patients. RESULTS: The assistance consists on a 90-min "Spiritual healing" session which includes educational lectures, "disobsession" (spirit release therapy), "passe" (laying on of hands) and person advice. Both patients had remitted depression when they were interviewed. CONCLUSIONS: Further studies would be necessary to report other religious/spiritual treatments in order to improve our understanding of the available practices used by patients and optimize the integration of conventional care with spiritual treatments.

Religiousness and headache: is there a relation? Results from a representative sample of adults living in a low-income community.

BACKGROUND: The use of religious behaviors to alleviate the consequences of stressful life circumstances is a frequent strategy employed by pain sufferers. Specifically in the field of headache research, to date, few studies have assessed spiritual and religious beliefs. OBJECTIVE: The objective of this article is to investigate the relation between religiousness (organizational, non-organizational and intrinsic) and headache disorders in a representative sample of adults living in a low-income community. METHODS: This was a cross-sectional, population-based study. In 2005, we conducted door-to-door interviews with 439 people, aged more than 18 years, randomly selected from a low-income community in Brazil. Four regression models were created to explain the relationships between religious involvement and headache, controlling for demographics, depression/anxiety and alcohol use and smoking. RESULTS: Of the 439 households contacted, at least one member from 383 (87.2%) households participated. We interviewed more women (74.4%) and more subjects aged 18-39 years. The mean age was 41.7 (SD 8.5) years. Bivariate analysis shows that high religious attendance, non-organizational religiousness and intrinsic religiousness were associated with presence of headache and presence of migraine. After the logistic regression models, only high non-organizational religiousness remained associated with presence of headache (odds ratio (OR): 1.22 (1.01-1.49)). All other religious variables were unrelated to the presence of headache and its types. CONCLUSION: There is a modest relationship between high non-organizational religiousness and presence of headache. Headache sufferers may use coping strategies such as private religious behaviors to try to overcome suffering.

Generalized anxiety disorder, subthreshold anxiety and anxiety symptoms in primary headache.

AIMS: The aim of the present study was to evaluate the association between generalized anxiety disorder, subthreshold anxiety (SubAnx) and anxiety symptoms in the prevalence of primary headache. METHODS: This cross-sectional study evaluated 383 people from a Brazilian low-income community. One-year prevalence rates of migraine, chronic migraine and tension-type headache were calculated. Anxiety symptoms were then separated into the following groups (based on DSM-IV criteria): no anxiety criteria; one anxiety criterion; two anxiety criteria; and generalized anxiety disorder (GAD). The control group (no headaches) was compared with headache sufferers for each anxiety group using an adjusted model controlled for confounding factors. RESULTS: GAD was present in 37.0% of participants and SubAnx in 16.6%. Those with SubAnx had a 2.28-fold increased chance of having migraine; 3.83-fold increased chance of having chronic migraine, a 5.94-fold increased chance of having tension-type headache and a 3.27-fold increased chance of having overall headache. Some anxiety criteria (irritability, difficulty with sleep, concentration problems, muscle tension and fatigue) had similar prevalence to International Classification of Headache Disorders (ICHD-II) headache criteria such as unilateral pain and nausea for migraine and chronic migraine. CONCLUSION: Headache sufferers seem to have a high prevalence of anxiety symptoms and SubAnx. In addition, the presence of two or more anxiety criteria (not necessarily fulfilling all the criteria for GAD) was associated with having a headache disorder.

Religiosity and tobacco and alcohol use in a Brazilian shantytown.

This article analyzes the role of religious involvement and religious beliefs in the prevalence and frequency of smoking and alcohol consumption. This was a cross-sectional, population-based study. In 2005, we conducted door-to-door interviews with 383 people, aged 18 years or more, randomly selected from the "Paraisopolis" shantytown in São Paulo, Brazil. Four regression models were created to explain the relationships among religious involvement, tobacco and alcohol use, controlling for demographic, social, and psychobehavioral factors. High religious attendance was associated with less alcohol use, alcohol abuse, tobacco use, and combined alcohol/tobacco use, as well as less days consuming alcoholic beverages per week, controlling for confounding factors. Additionally, high nonorganizational religious behavior was associated with less tobacco and combined alcohol/tobacco use. Religiosity plays an important role in the control of alcohol and tobacco use in a shantytown setting; further management initiatives in the area should consider this issue. The study's limitations are noted.

Social anxiety score is high in adolescents with chronic migraine.

BACKGROUND: Social anxiety disorder, also known as social phobia, is a marked and persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. It usually begins in mid-adolescence and has a chronic course and interferes in academic, social, family and personal functioning. Recent studies have shown that social anxiety disorder is more prevalent in adults with migraine. Little evidence on this subject is available for the adolescent population. METHODS: This study was performed between August 2009 and August 2010; all patients were recruited in schools, pediatric or neuropediatric facilities, and were submitted to a detailed headache questionnaire, which consisted of demographic and clinical data. To evaluate social anxiety, the Social Phobia Inventory was used. RESULTS: A total of 151 subjects were evaluated: 50 had chronic migraine, 50 had episodic migraine and 51 were control subjects. In the chronic migraine group, the mean score in the Social Phobia Inventory was 18.5 ± 12.4, which was significantly higher than in the episodic migraine group (12.1 ± 8.1) and in the control group (13.8 ± 10.8; F(2131) = 4.8, P= 0.010). The mean score, however, was not significantly different between the control and episodic migraine groups. CONCLUSIONS: Chronic migraine is strongly associated with high social anxiety score, regardless of demographic data and pain intensity. The total burden of migraine may be increased with social anxiety disorder comorbidity.

Validation of the Duke Religion Index: DUREL (Portuguese version).

The purpose of the current study was to examine the psychometric properties of the Portuguese version of the Duke Religion Index (PDUREL) in a community setting. PDUREL was translated and adapted for administration to 383 individuals from a population-based study of low-income community-dwelling adults. The PDUREL intrinsic subscale and total scores demonstrated high internal consistency (alphas ranging from 0.733 for the total scale score to 0.758 for the intrinsic subscale). Correlations among the DUREL subscales were also examined for evidence of discriminant validity. Correlations were ranging from 0.36 to 0.46, indicating significant overlap between the scales without marked redundancy. PDUREL is a reliable and valid scale. The availability of a comprehensive, but brief measure of religiousness can help to study the role of religiousness in health by researchers from countries that speak the Portuguese language.

Religiousness, health, and depression in older adults from a brazilian military setting.

This study aims to analyze the association between religious attendance, self-reported religiousness, depression, and several health factors in 170 older adults from a Brazilian outpatient setting. A comprehensive assessment was conducted including sociodemographic characteristics, religious attendance, self-reported religiousness, functional status, depression, pain, hospitalization, and mental status. After adjusting for sociodemographics, (a) higher self-reported religiousness was associated with lower prevalence of smoking, less depressive symptoms, and less hospitalization and (b) higher religious attendance was only associated with less depressive symptoms. Religiousness seems to play a role in depression, smoking, and hospitalization in older adults from a Brazilian outpatient setting. Self-reported religiousness was associated with more health characteristics than religious attendance.

Increased variability of motor cortical excitability to transcranial magnetic stimulation in migraine: a new clue to an old enigma.

Increased, decreased or normal excitability to transcranial magnetic stimulation (TMS) has been reported in the motor (M1) and visual cortices of patients with migraine. Light deprivation (LD) has been reported to modulate M1 excitability in control subjects (CS). Still, effects of LD on M1 excitability compared to exposure to environmental light exposure (EL) had not been previously described in patients with migraine (MP). To further our knowledge about differences between CS and MP, regarding M1 excitability and effects of LD on M1 excitability, we opted for a novel approach by extending measurement conditions. We measured motor thresholds (MTs) to TMS, short-interval intracortical inhibition, and ratios between motor-evoked potential amplitudes and supramaximal M responses in MP and CS on two different days, before and after LD or EL. Motor thresholds significantly increased in MP in LD and EL sessions, and remained stable in CS. There were no significant between-group differences in other measures of TMS. Short-term variation of MTs was greater in MP compared to CS. Fluctuation in excitability over hours or days in MP is an issue that, until now, has been relatively neglected. The results presented here will help to reconcile conflicting observations.

Sensitivity to aversive stimulation, posttraumatic symptoms and migraines: what do they have in common?

Studies have suggested that the high comorbidity observed between chronic migraine and anxiety disorders can be mediated through a third factor namely increased sensitivity to aversive stimulation. This trait may predispose for both chronic migraines, through medication overuse as an avoidance response, and anxiety disorders. Additional studies have shown that hyper sensitivity to aversive stimulation, migraine chronification and anxiety disorders share other characteristics such as serotonergic mediation and personality traits. Preliminary analysis of empirical data comparing the frequency the impact of traumatic events over chronic [CM] and episodic migraine [EM] patients gives further support to this hypothesis. In spite of CM and EM did not differ in terms of the occurrence of traumatic events, CM patients that had experienced at least one traumatic event during their lives had higher scores in re-experiencing and avoidance (but not in hyperarousal) symptoms than CM patients. These observations suggest that traumatic events have greater impact over CM than over EM patients.

The prevalence of migraine and probable migraine in a Brazilian favela: results of a community survey.

OBJECTIVES: The objectives of the present study were to estimate the 1-year prevalence of primary headaches and the role of select socio-demographic aspects in a representative sample of adults living in a Brazilian shanty town. BACKGROUND: Some socio-demographic factors, such as marital status, income, education, and job status have been described in studies with contentious results. Nevertheless, few studies have assessed the prevalence of headache and the role of socio-demographic aspects in very low-income communities. METHODS: A cross-sectional, population-based study was undertaken. Door-to-door interviews with 383 people were conducted. Individuals were aged greater than 18 years, randomly selected from the "Paraisopolis" shanty town in São Paulo, Brazil. The degree of the association was calculated through prevalence ratios and adjusted with backward logistic regression by gender, age, and some socio-demographic factors, including living conditions. RESULTS: The estimated 1-year prevalence of headache, migraine, chronic migraine, and tension-type headache were 47% (CI 95%: 39.5-52.6%), 20.4% (CI 95%: 16.6-24.9%), 8.4% (CI 95%: 6.1-12.0%), and 6.2% (CI 95%: 3.3-9.8%), respectively. Migraine was more prevalent in women and among employed people. No other relationship was found. The overall prevalence of migraine and chronic migraine in this very low-income community were high and migraine was associated with gender and job status. CONCLUSION: The overall prevalence of migraine and chronic migraine in this very low-income community were high and tension-type headache was low. A paradox was noted in the employment status and income association, one would expect higher levels of migraine in a low-income population, but higher numbers were found in those employed vs unemployed. These findings will need to be replicated in other population samples.
