Child development and wellness are strictly dependent on several factors among them physical activity, a proper nutrition and, of critical importance, a healthy mind. Psychopathologies like attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD) have a direct negative impact on social, academic or occupational functioning of the affected children. If left untreated, these pathologies may progress to adulthood, thus requiring research strategies on conventional and nonconventional modalities of treatment. In this pilot study, conducted during the academic year 2015/2016, a combination of exercises of TaijiQuan (TJQ) and Qi Gong (QG) were taught to four selected children, three males and one female, aged between 6 and 10, suffering from the above mentioned behavioural disorders. The main goal was to understand if it is possible to achieve any kind of improvement in their condition, by evaluating the scores of the Achenbach Teacher's Report Form (TRF) in the beginning and ending of the experimental period. Results showed very interesting improvements in symptoms of CD, ODD and ADHD-HI (hyperactive-impulsive), while ADHD-PI (predominantly inattentive) showed only minor improvements. The overall symptom improvement was 43% across pathologies, which demonstrates that TJQ and QG may be a promising treatment of symptoms for children with behavioural disorders. More research is needed with controlled experimental designs and statistically representative samples in order to fully comprehend the versatility of these modalities.
PURPOSE: To evaluate the effects of sustained deep inspiration in the prevention of postoperative pulmonary complications, the hormonal and immunological responses in patients submitted to abdominal surgery.METHODS: This randomized clinical trial study included 75 patients submitted to abdominal surgery, of which 36 were randomly allocated in the experimental group and underwent sustained deep inspiration during five seconds, in three sets of ten repetitions per day. The others 39 patients were allocated in the control group and were not submitted to any breathing exercise. The following parameters were measured preoperatively, 24h and 48h postoperatively: chest x-ray, serum ACTH, cortisol, IL-4, IL-10, TNF-α, forced expiratory volume in first second (FEV1), forced expiratory flow 25-75% (FEF 25-75), forced vital capacity (FVC), paO2 and paCO2.
RESULTS: Mean serum cortisol in patients of the experimental and control groups before surgery were 12.8 mcg/dl (4.6-50) and 10.48 mcg/dl (1-29.1), respectively (p=0.414). The experimental group had significantly increase in serum cortisol levels, 23.6 mcg/dl (9.345.8), especially 24h postoperatively (p=0.049).
CONCLUSION: Sustained deep inspiration in patients submitted to abdominal surgery determined important changes in serum cortisol, however, without significantly influence the postoperative pulmonary complications and the endocrine and immune responses.
The aim of the present study was to identify formulas used at Men-Tsee-Khang (Tibetan Medical and Astrological Institute), India, for the treatment of neuropsychiatric disorders and to compare the Tibetan usage of particular ingredients with pharmacological data from the scientific database. Using ethnographic methods, five doctors were selected and interviewed. A correlation was observed between central nervous system disorders and rLung, one of the three humors in Tibetan medicine, which imbalance is the source of mental disorders, and ten multi-ingredient formulas used to treat the imbalance of this particular humor were identified. These formulas utilize 61 ingredients; among them were 48 plant species. Each formula treats several symptoms related to rLung imbalance, so the plants may have therapeutic uses distinct from those of the formulas in which they are included. Myristica fragrans, nutmeg, is contained in 100% of the formulas, and its seeds exhibit stimulant and depressant actions affecting the central nervous system. Preclinical and clinical data from the scientific literature indicate that all of the formulas include ingredients with neuropsychiatric action and corroborate the therapeutic use of 75.6% of the plants. These findings indicate a level of congruence between the therapeutic uses of particular plant species in Tibetan and Western medicines.

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world’s vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation.

This study aims to test the effects of yoga on health-related quality of life, life satisfaction, cancer-related fatigue, mindfulness, and spirituality compared to conventional therapeutic exercises during (neo)adjuvant cytotoxic and endocrine therapy in women with breast cancer. In a randomized controlled trial 92 women with breast cancer undergoing oncological treatment were randomly enrolled for a yoga intervention (YI) (n = 45) or for a physical exercise intervention (PEI) (n = 47). Measurements were obtained before (t 0) and after the intervention (t 1) as well as 3 months after finishing intervention (t 2) using standardized questionnaires. Life satisfaction and fatigue improved under PEI (p < 0.05) but not under YI (t 0 to t 2). Regarding quality of life (EORTC QLQ-C30) a direct effect (t 0 to t 1; p < 0.001) of YI was found on role and emotional functioning, while under PEI only emotional functioning improved. Significant improvements (p < 0.001) were observed at both t 1 and t 2 also for symptom scales in both groups: dyspnea, appetite loss, constipation, and diarrhea. There was no significant difference between therapies for none of the analyzed variables neither for t 1 nor for t 2. During chemotherapy, yoga was not seen as more helpful than conventional therapeutic exercises. This does not argue against its use in the recovery phase.
Oxytocin, a peptide that functions as both a hormone and neurotransmitter, has broad influences on social and emotional processing throughout the body and the brain. In this study, we tested how a polymorphism (rs53576) of the oxytocin receptor relates to two key social processes related to oxytocin: empathy and stress reactivity. Compared with individuals homozygous for the G allele of rs53576 (GG), individuals with one or two copies of the A allele (AG/AA) exhibited lower behavioral and dispositional empathy, as measured by the “Reading the Mind in the Eyes” Test and an other-oriented empathy scale. Furthermore, AA/AG individuals displayed higher physiological and dispositional stress reactivity than GG individuals, as determined by heart rate response during a startle anticipation task and an affective reactivity scale. Our results provide evidence of how a naturally occurring genetic variation of the oxytocin receptor relates to both empathy and stress profiles.

The current study investigated the comprehension of mindfulness-based cognitive behavioral therapy (MBCT) by patients with resistant depression at the Psychiatry Institute of the Federal University of Rio de Janeiro, Brazil. This was the first time the model was used in the institution to treat these patients. In this study, 45 patients were invited to participate in a baseline session of MBCT that consisted in the explanation of the model and experimental exercises conducted by two experienced therapists. Twenty eight patients accepted to participate. At the end of the intervention, the patients completed a self-administered questionnaire designed by our ambulatory to assess their understanding of the method’s goals. Patients with anxiety disorder was also accessed for group comparison. More than 75% of the patients rated the intervention as comprehensible and workable. Compared to patients with depression, patients with anxiety had a better understanding of the mindfulness framework (6.5%) and the meaning of cognitive behavioral therapy (17.6%). Patients that completed the intervention described the baseline session of MBCT as comprehensive and acceptable. These results may allow possible future developments in the practice of mindfulness as a treatment applicable in many condition and settings even in the Brazilian context.
BACKGROUND: Autism spectrum disorder is a condition that affects all races, ethnic and socioeconomic groups. With a high incidence ratio of one in every 68, it has become one of the most discussed psychiatric disorders. For this reason, the need for investigating novel treatments has been emerging. Qigong, a traditional Chinese mind-body technique, has already proven to be able to reduce symptoms of several physical and psychological illnesses.OBJECTIVE: The purpose of this systematic review is to examine and categorize the current scientific evidence regarding the efficacy of Qigong on children suffering from autism spectrum disorders.
SEARCH STRATEGY: A systematic literature search of the electronic scientific databases PubMed, Clinical Trials.gov, BioMed Central, PubMed Central and Google Scholar was performed to identify studies of Qigong in the treatment of children with autism spectrum disorder.
INCLUSION CRITERIA: This review included randomized controlled trials, replication studies, retrospective studies and observational follow-up studies of Qigong on children with autism spectrum disorder. Case reports and case series were excluded.
DATA EXTRACTION AND ANALYSIS: Two researchers independently evaluated the methodological quality of all included studies. Any discrepancies were solved by discussion until consensus was achieved.
RESULTS: Our literature search identified 157 publications, and 10 additional publications from hand search of references. After duplicate removal, 103 records remained. After the title/abstract screening, 19 publications were obtained for detailed evaluation. After detailed evaluation, 10 studies were included. Seven studies were conducted with small children with 2-6 years old employing Qigong massage, and three studies were conducted with older children aged 7-17 years old applying both Qigong massage (one study) and Neigong (two studies).
CONCLUSION: Studies demonstrated that Qigong has interesting and promising applicability and effect on children with autism spectrum disorder and should be tested further. Despite the need for more rigorous controlled studies, Qigong seems to be able to decrease severity of individual sensory, behavioural, and language components of autism, and improve self-control, sociability, sensory and cognitive awareness as well as healthy-physical behaviour. Besides positive effect on children and adolescents, benefits seem to extend to parents and caregivers as well. However, quality of methodology seems to be insufficient to state that Qigong is an alternative to common behavioural therapies. We suggest that, until more investigation is performed, Qigong may only be used as a complement, or when behavioural therapies are not accessible.
Stroke is a severe clinical manifestation of sickle cell anemia (SCA). Despite the prognostic relevance of transcranial Doppler (TCD), more accurate tools to assess stroke risk in children with SCA are required. Here, we describe the effect of clinical, laboratory, and molecular features on the risk of stroke and high-risk TCD in children from the newborn cohort of Minas Gerais, Brazil. Outcomes studied were acute cerebral ischemia and high-risk TCD. Clinical and hematological data were retrieved from children’s records. Genetic markers, which were known for their association with stroke risk, were genotyped by polymerase chain reaction/restriction fragment length polymorphism and sequencing. The cumulative incidence of acute cerebral ischemia by the age of 8 years was 7.4 % and that of high-risk TCD by the age of 11.5 years was 14.2 %. The final multivariate model for acute cerebral ischemia risk included high white blood cell count and reticulocyte count, acute chest syndrome rate, and the single nucleotide polymorphisms (SNPs) TEK rs489347 and TNF-α rs1800629. The model for high-risk TCD included high reticulocyte count and the SNPs TEK rs489347 and TGFBR3 rs284875. Children with risk factors should be considered for intensive risk monitoring and for intervention therapy.
Ethnopharmacological relevanceSyzygium cumini (L.) Skeels (Myrtaceae), commonly known as “jambolão” in Brazil is widely used in folk medicine against leishmaniasis, inflammation, chronic diarrhea, and ulcers. It is one of the most commonly used plants for the treatment of diabetes worldwide. In previous studies, Syzygium cumini was shown to possess antihyperlipidemic and anti-allergic properties, and to exhibit good performance as an antimicrobial agent against bacteria, fungi, and protozoa parasites of the genus Leishmania and Trypanosoma. This study was aimed at evaluating the effects of S. cumini essential oil (ScEO) and its major component α-pinene on Leishmania (Leishmania) amazonensis, as well as their cytotoxicity and possible mechanisms of action.
Materials and methods
To evaluate the anti-proliferative effect on Leishmania, effects on promastigote and axenic amastigote forms were assessed using tetrazolium salt (MTT) assay. The intramacrophagic amastigotes were exposed to ScEO and α-pinene to determine the survival index. To gain insight into the mechanism of action involved in the effect on the samples, we evaluated the modulation of macrophage activation state by observing structural (phagocytic and lysosomal activities) and cellular (nitric oxide increase) changes. To assess the safety profile of ScEO and α-pinene, murine macrophages and human red blood cells were treated with ScEO and α-pinene and the selectivity index was calculated for each treatment.
Results
α-Pinene was effective against Leishmania amazonensis promastigote forms, with a half-maximal inhibitory concentration (IC50) value of 19.7µg/mL. α-Pinene was more active (IC50 values of 16.1 and 15.6µg/mL against axenic and intracellular amastigotes, respectively) than ScEO (IC50 values of 43.9 and 38.1µg/mL against axenic and intracellular amastigotes, respectively). Our results showed that the anti-Leishmania effects were mediated by immunomodulatory activity, as evidenced by the observed increases in both phagocytic and lysosomal activity, and the elevated NO levels. ScEO and α-pinene exhibited low cytotoxicity against murine macrophages and human erythrocytes. The 50% cytotoxicity concentration (CC50) values for the macrophages in the MTT assay were 614.1 and 425.2µg/mL for ScEO and α-pinene, respectively, while the corresponding half-maximal hemolytic concentration (HC50) values were 874.3 and 233.3µg/mL.
Conclusions
Taken together, the results demonstrate that ScEO and its major constituent α-pinene have significant anti-Leishmania activity, modulated by macrophage activation, with acceptable levels of cytotoxicity in murine macrophages and human erythrocytes. Further work is warranted, involving more in-depth mechanistic studies and in vivo investigations.
Individuals who are homozygous for the G allele of the rs53576 SNP of the oxytocin receptor (OXTR) gene tend to be more prosocial than carriers of the A allele. However, little is known about how these differences manifest behaviorally and whether they are readily detectable by outside observers, both critical questions in theoretical accounts of prosociality. In the present study, we used thin-slicing methodology to test the hypotheses that (i) individual differences in rs53576 genotype predict how prosocial observers judge target individuals to be on the basis of brief observations of behavior, and (ii) that variation in targets’ nonverbal displays of affiliative cues would account for these judgment differences. In line with predictions, we found that individuals homozygous for the G allele were judged to be more prosocial than carriers of the A allele. These differences were completely accounted for by variations in the expression of affiliative cues. Thus, individual differences in rs53576 are associated with behavioral manifestations of prosociality, which ultimately guide the judgments others make about the individual.

Objective: The practice of yoga has been proven to have positive effects on reducing insomnia. Studies have also shown its effects on reducing climacteric symptoms. To date, however, no studies that evaluate the effects of yoga on postmenopausal women with a diagnosis of insomnia in a randomized clinical trial have been conducted. The aim of this study was to evaluate the effect of yoga practice on the physical and mental health and climacteric symptoms of postmenopausal women with a diagnosis of insomnia. Methods: Postmenopausal women not undergoing hormone therapy, who were 50 to 65 years old, who had an apnea-hypopnea index less than 15, and who had a diagnosis of insomnia were randomly assigned to one of three groups, as follows: control, passive stretching, and yoga. Questionnaires were administered before and 4 months after the intervention to evaluate quality of life, anxiety and depression symptoms, climacteric symptoms, insomnia severity, daytime sleepiness, and stress. The volunteers also underwent polysomnography. The study lasted 4 months. Results: There were 44 volunteers at the end of the study. When compared with the control group, the yoga group had significantly lower posttreatment scores for climacteric symptoms and insomnia severity and higher scores for quality of life and resistance phase of stress. The reduction in insomnia severity in the yoga group was significantly higher than that in the control and passive-stretching groups. Conclusions: This study showed that a specific sequence of yoga might be effective in reducing insomnia and menopausal symptoms as well as improving quality of life in postmenopausal women with insomnia.
