RESUMO

Gestational hypertension can lead to fetal complications, and, if untreated, high blood pressure during pregnancy may cause eclampsia and even death in the mother and fetus. Exercise is a strategy for preventing blood pressure disorders. There is little knowledge about the physiological impacts of different physical types of training on blood pressure during pregnancy. For that, this meta-analysis aimed to compare the effects of different physical exercise modalities (i.e., aerobic training-AT, strength training-ST, and combined training-AT + ST) on systolic blood pressure (SBP) and diastolic blood pressure (DBP) of pregnant women. A search was performed on PUBMED, LILACS, CINAHL, Sport discus, EMBASE, SCOPUS, and Cochrane Central Register of Controlled Trials to identify researchers. From 3,450 studies, 20 and 19 were included in the qualitative and quantitative analyses. AT studies presented a medium effect size (ES) on SBP [-0.29 (-2.95 to 2.36) p = 0.83], with substantial heterogeneity (I2 = 64%), and had a large impact on DBP [-1.34 (-2.98 to 0.30) p = 0.11], with moderate heterogeneity (I2 = 30%). ST researchers showed a large ES on SBP [-1.09 (-3.66 to 1.49) p = 0.41], with a reduced heterogeneity (I2 = 0%), and a medium ES on DBP [-0.26 (-2.77 to 2.19) p = 0.83] with moderate heterogeneity (I2 = 38%). AT + ST studies had a large ES on SBP [-1.69 (-3.88 to 0.49) p = 0.13] and DBP [-01.29 (-2.26 to 0.31) p = 0.01] with considerable (I2 = 83%) and moderate heterogeneity (I2 = 47%), respectively. These findings are essential for developing new research protocols to avoid gestational hypertension and preeclampsia. AT + ST had a large impact on the SBP and DBP reduction; however, there is a need for more similar procedures to reduce heterogeneity between studies, promoting consensual results. Systematic Review Registration: [PROSPERO], identifier [CRD42021256509].

RESUMO

INTRODUCTION: Interpersonal negotiation skills (INS) comprise actions used to solve social situations between interacting individuals involving different needs or desires. These abilities are part of one's social competence and may be impaired in some psychiatric conditions. There are few validated psychometric tools for measuring INS in the literature. This pilot study aimed to investigate some basic psychometric properties of the Brazilian version of the Interpersonal Negotiation Strategies Interview (INSI) in children and adolescents. METHODS: We developed a new version of the INSI adapted to the Brazilian culture using eight different dilemmas in dyadic situations (with peers and adults), presented visually as drawings on cards. A group of psychologists and psychiatrists chose and adapted the dilemmas formerly proposed by the original version. The same scoring criteria as for the original instrument were used. A total of 20 children and adolescents were included in this pilot study. We investigated test reliability using measures of interrater reliability, test-retest, and internal consistency. The content validity of the INSI was also evaluated by comparison with scores from the Child Behavior Checklist-Revised (CBCL). RESULTS: Internal consistency and test-retest evaluations were acceptable (rater 1: α = 0.77; rater 2: α = 0.72); the reliability of the instrument was excellent (K = 0.078; intraclass correlation coefficient = 0.98; 95% confidence interval 0.97-0.99); and content validity was strongly significant (p < 0.001). CONCLUSIONS: Preliminary results suggest that this version of the INSI has good interrater reliability and internal consistency and constitutes a promising tool to assess social competence.

RESUMO

Post-exercise hypotension is of great clinical relevance and also in sports training settings, as recovery speed is important. The aim of this study was to compare the influence of different recovery methods on post-exercise hemodynamic response. Twelve male paraplegic sportsmen (25.40 ± 3.30 years) performed a strength training (ST) session using the bench press exercise. After the ST, three recovery methods were randomly performed over a 15-min period: passive recovery (PR), cold-water (CW) and dry needle (DN). Blood pressure (BP), heart rate (HR) and myocardial oxygen were measured before and post ST, as well as post the recovery method. Results: Dry needling induced lower systolic blood pressure (SBP) immediately after the treatment when compared with the other recovery methods, but the contrary was observed at 50 and 60-min post recovery, where records with DN exhibit higher mean values (η2p = 0.330). There were no differences in post-exercise diastolic BP and mean BP between recovery methods. There was a significantly higher HR after the PR method, when compared with CW and with DN (η2p = 0.426). The same was observed for double product and for myocardial oxygen, though with a larger effect size (η2p = 0.446). We conclude that dry needling seems to induce a faster SBP lowering immediately after the procedure but at 50-min post procedure the cold-water method showed better result. As for HR, both procedures (DN and CW) showed a better recovery when compared with passive recovery, along the several moments of measurement.

RESUMO

Social interaction difficulties are amongst the most prevalent and pervasive adverse outcomes for children and adolescents with ADHD. Problem-solving strategies are impaired in affected individuals, according to the literature. This study aimed to investigate the social problem-solving skills of children and adolescents with and without ADHD, using objective quantitative measures provided by the Interpersonal Negotiation Strategies Interview (INSI). Since verbal communication skills and working memory may be impaired in ADHD, we investigated their contribution to the performance. Forty-three children and adolescents with ADHD and 27 clinical controls with clinical diagnoses other than ADHD completed the INSI along with measures of verbal communication skills (Verbal Comprehension Index [VCI]): Similarities, Vocabulary and Comprehension subtests from the Wechsler Battery, visual (Corsi Blocks) and verbal (Digit Span) working memory tasks. Groups performed similarly on measures of intellectual functioning, working memory, and verbal communication. For the entire sample, VCI scores were positively correlated with INSI performance scores. The ADHD group performed worse on the INSI than the clinical control group. Linear regression analysis showed that inattention and hyperactivity/impulsivity levels and Similarities predicted INSI's performance. Our findings indicate that interpersonal negotiation difficulties in ADHD are related to DSM-5 defining symptoms of the disorder.

RESUMO

OBJECTIVE: In the last decade, the research about mind-wandering (MW) significantly improved and allowed us to depth the phenomenology of thoughts. Prototypically, excessive MW was linked with ADHD symptoms. However, many studies have demonstrated the need to relate the type of mind-wandering with specific phenomenological presentations. METHOD: Participants (N = 53; 54.7% male; age range 18-36 years) selfreported the Mind Excessively Wandering Scale (MEWS), and they were investigated for ADHD, impulsivity levels, and anxiety/depressive symptoms. RESULTS: The exploratory analysis indicated a meaningful correlation between MEWS and anxiety traits and depressive symptoms. There was no significant relationship with ADHD symptoms. CONCLUSION: These findings based our discussion about MW's phenomenology considering the novel classification model based on the consideration of clinical markers such as thoughts' content.

RESUMO

OBJECTIVES: This study aimed to report motor tics worsening by prednisolone acute treatment, despite the use of aripiprazole and clonidine. It was also aimed to discuss the mechanisms involved in neuropsychiatric adverse effects with the use of corticosteroids. METHODS: It was reported a 7-year-old boy patient with a history of autism spectrum disorder and motor tics. He has remitted motor tics with an association between aripiprazole and clonidine. However, was registered motor tics' recurrence with acute use of prednisolone. CONCLUSIONS: The neuropsychiatric adverse effects mediated by corticosteroid use are low explored, mainly in pediatric clinical practice. The prednisolone prescription is widespread in childhood and, considering some vulnerable conditions to this type of adverse effects, is imperative.

RESUMO

Impulsivity has a strong genetic component and is considered an endophenotype in many psychiatric disorders. Impulsivity in adult ADHD has become a focus of interest more recently because of its suggested prominence in this age. Objective: This study aimed to access self-reported impulsivity levels in biological parents of ADHD offspring, according to their status: non-ADHD (controls), remitted, nonremitted. Method: Impulsivity levels of 155 parents of ADHD children were compared according to their status using the Barratt Impulsiveness Scale (BIS-11). Results: The ADHD group presented the highest levels of impulsivity compared with all other groups. The remitted ADHD and control groups showed no significant differences in impulsivity levels. Conclusion: Impulsivity tended to remit alongside ADHD symptoms in remitters and to persist in those presenting with the residual form of adult ADHD suggesting it should not be considered as an endophenotype. Only the attentional dimension was impaired, cautioning against Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) impulsivity proposed criteria.

RESUMO

Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-V) diagnostic criteria for attention-deficit hyperactivity disorder (ADHD) has reemphasized impairment although many studies have demonstrated that such approach may inflate prevalence rates. However, there is no consensus on how impairment should be measured and a myriad of approaches in different studies make comparisons difficult. Objective: To investigate whether impairment measured using a previous validate quantitative measure modifies prevalence rates in a sample of Brazilian children and adolescents. Method: Of 109 children (72 males, 37 females), mean age of 12.4 years, 68 were with ADHD (according to DSM criteria, except for impairment) and 41 were typically developing children. All were evaluated with semi-structured interviews and completed the Functional Impairment Scale (FIS). Results: Thirty-five percent of ADHD cases had impairment in one single domain or no impairment at all (among school performance, social life, family life, and self-perception) in the FIS. Conclusion: Disregarding impairment clearly inflates ADHD diagnosis.

RESUMO

AIM: To characterize the population treated with SBRT for early-stage primary lung tumors in our institution, determine their outcomes, and identify potential prognosis factors. BACKGROUND: Stereotactic radiotherapy (SBRT) is an alternative treatment for inoperable patients with early-stage lung cancer. It confers a local control rate around 90% at 3 years, and 2-3 year overall survival rates of 43-60% in this population. MATERIALS AND METHODS: We retrospectively analyzed all patients treated in our department between 2012 and 2017 and evaluated local progression-free survival (L-PFS), nodal or distant progression-free survival (ND-PFS), global progression-free survival (G-PFS), overall survival (OS), and disease specific survival (DSS). Univariate (UVA) and multivariate (MVA) models were built to assess the influence of each variable. RESULTS: We identified 218 patients with 233 tumors. Most were male (78.9%) with a median age of 73 years. Median follow-up was 22 months. At 18 months, L-PFS was 93.7%, ND-PFS was 82.2%, G-PFS was 76.0%, DSS was 90.5%, and OS was 78.0% in ≤ T2 tumors. On UVA, T2 tumors were associated with lower L-PFS, G-PFS and DSS than T1, with no significant impact on ND-PFS or OS, an effect that persisted on MVA. On UVA, L-PFS and G-PFS were negatively influenced by female gender and a 5-fraction schedule was associated with worse G-PFS, which was not confirmed on MVA. CONCLUSION: Our local and distant control rates and survival were similar to those previously reported. On MVA, T2 tumors displayed lower L-PFS, G-PFS and DSS, with no difference in OS.

RESUMO

BACKGROUND: Mind Wandering (MW) has been associated with ADHD in a very small number of studies with adults and children. However, anxiety and depression have also been associated with MW and both are often comorbid with ADHD. The aim of this study was to investigate the role of anxiety and depression in MW in patients with ADHD. METHODS: The Mind Excessively Wandering Scale (MEWS) compared the levels of MW controlling for the presence of anxiety and depression symptoms in 78 adolescents (53 males and 25 females) comprising ADHD, clinical controls and typically developing individuals. Correlational analysis between MEWS score, demographic variables, ADHD, anxiety and depressive symptoms was performed using simple and multiple linear regression analysis demonstrating that only anxiety predicted MW scores. On a second analysis, we compared Anxiety and Non-Anxiety as well as ADHD and non-ADHD groups. RESULTS: Levels of MW were significantly correlated with anxiety symptoms, but not with depression. In addition, there were no differences in ADHD and non-ADHD groups regarding MW levels. CONCLUSIONS: Our results suggest MW is associated with anxiety levels, independently of an ADHD diagnosis.

RESUMO

Sousa, AC, Gomes, TM, Sousa, MS, Saraiva, AR, Araujo, GS, Figueiredo, T, and Novaes, JS. Static stretch performed after strength training session induces hypotensive response in trained men. J Strength Cond Res 33(11): 2981-2990, 2019-The purpose of this study was to compare the acute effect of 3 different combinations between passive static stretching exercises (SE) with resistance training (RT) on blood pressure (BP) response in normotensive trained men. Twenty-six volunteer subjects (age: 26.1 ± 5.4 years; body mass: 86.5 ± 10.5 kg; height: 1.78 ± 0.6 cm) participated in this study. After assessing 10 repetition maximum loads for the bench press, lat pulldown, shoulder press, leg press, leg extension, and leg curl, the subjects were randomly assigned on 3 experimental conditions: (a) static SE were performed before the RT session (SE + RT); (b) static SE were performed after the RT session (RT + SE); and (c) static SE were performed between the RT session (RTSE). The BP was measured for 60 minutes after the RT session. The 2-way analysis of variance for repeated measures showed no significant difference (p > 0.05) between the experimental conditions. In within comparisons, only the RT + SE experimental condition did not cause significant increases (p = 0.07) on systolic blood pressure (SBP) when compared the baseline and post-test moments (132.2 ± 10.7 vs. 141.3 ± 18.1 mm Hg). In addition, hypotensive effects were found in SBP only in the RT + SE experimental condition when compared SBP baseline (132.2 ± 10.7 mm Hg) vs. SBP30 minutes (121.7 ± 11.8 mm Hg; p = 0.04), SBP45 minutes (120.6 ± 9.8 mm Hg; p = 0.03), and SBP60 minutes (120.0 ± 7.9 mm Hg; p = 0.00). These findings suggest that performing static SE after the RT session provide an ideal combination for a postexercise hypotensive response from 30 minutes after exercise (and this change was enhanced up to 60 minutes). In conclusion, strength and conditioning professionals can prescribe static SE after RT if the goal is to reduce blood pressure after training.

RESUMO

BACKGROUND: The purpose of this study was to compare traditional strength training (TST) versus complex and contrast training (CCT) on sprint, change of direction speed (COD) and squat jump (SJ) in young male soccer players. METHODS: Twenty-two soccer players (age: 18.4±0.4 years, body mass: 70.2±9.1 kg, height: 179.9±7.5 cm), were randomly assigned to one of two groups: TST (N.=12) and CCT (N.=10). The study was conducted using a randomized experimental design over an eight-week period. The participants assigned to the CCT group performed high-power exercises paired with high-velocity exercises. The participants assigned to the TST group performed resistance exercises in a straight-set forma. During the study period, sprint tests for 5, 10, 20 and 30 m split times, COD and SJ were applied. A two-way ANOVA was applied, and the alpha level was P<0.05. RESULTS: The results demonstrated that the CCT regimen elicited significant within-group differences in 5 m sprint time (1.032 s to 0.997 s, pre- and postintervention, respectively, effect size (ES) = -0.5, medium; P=0.04), COD (5.963 s to 5.639 s, pre- and postintervention, respectively, ES -2.7, large; P<0.001) and SJ (30.9 cm to 34.4 cm, pre- and postintervention, respectively, ES =0.8, large; P<0.001). Conversely, the TST did not elicit significant within-group differences for any of the dependent variables. No differences were found between groups at the post-test time point. CONCLUSIONS: In conclusion, the CCT protocol could be used to improve sprint, COD and SJ in male soccer players.

RESUMO

Abstract Introduction: The concept of mind wandering refers to periods during which attention and content of thoughts depart from the original idea or activity being performed. The phenomenon occurs commonly in the general population and the Mind Wandering Excessively Scale (MEWS) evaluates its frequency, intensity and related negative outcomes. Objective: To describe the cross-cultural adaptation of the MEWS. Methods: Cross-cultural adaptation of the original scale followed five consecutive steps: translation, backtranslation, appreciation of semantic equivalence and administration to a convenience sample to 20 adults with attention deficit hyperactivity disorder (ADHD) and 20 normal controls. Results: Results indicated a satisfactory equivalence between the original and translated versions. A synthesis version for Brazilian Portuguese is presented. Conclusions: MEWS provides information on thought activity, which is particularly important in ADHD cases. The Brazilian Portuguese version would be welcome to address specific treatment responses and obtain new outcome measures


Resumo Introdução: O conceito de devaneio se refere a períodos nos quais a atenção e o conteúdo do pensamento de distanciam da ideia original ou da atividade que estava sendo realizada. O fenômeno ocorre na população em geral, e a Escala Mind Excessively Wandering Scale (MEWS) avalia sua frequência, intensidade e desfechos negativos associados. Objetivos: Descrever a adaptação transcultural da MEWS. Métodos: A adaptação transcultural envolveu cinco etapas: tradução, retrotradução, apreciação da equivalência semântica e administração em amostra de conveniência composta de 20 adultos com transtorno do déficit de atenção com hiperatividade (TDAH) e 20 controles normais. Resultados: Os resultados demonstraram equivalência satisfatória entre as versões original e traduzida. Uma versão síntese para o português brasileiro é apresentada. Conclusão: A MEWS fornece informações importantes sobre atividade mental, algo particularmente importante em casos de TDAH. A versão em português brasileiro deverá ser bem acolhida, permitindo investigar respostas específicas ao tratamento e obter novas medidas de desfechos.

RESUMO

This study compared the effect of a strength training session performed at different exercise orders and rest intervals on blood pressure and heart rate variability (HRV). Fifteen trained men performed different upper body exercise sequences [large to small muscle mass (SEQA) and small to large muscle mass (SEQB)] in randomized order with rest intervals between sets and exercises of 40 or 90 seconds. Fifteen repetition maximum loads were tested to control the training intensity and the total volume load. The results showed, significant reductions for systolic blood pressure (SBP) for all sequences compared to baseline and, post-exercise: SEQA90 at 20, 30, 40, 50 and 60 minutes; SEQA40 and SEQB40 at 20 minutes and SEQB90 at 10, 20, 30, 40, 50 and 60 minutes. For diastolic blood pressure (DBP), significant reductions were found for three sequences compared to baseline and, post-exercise: SEQA90 and SEQA40 at 50 and 60 minutes; SEQB40 at 10, 30 and 60 minutes. For HRV, there were significant differences in frequency domain for all sequences compared to baseline. In conclusion, when performing upper body strength training sessions, it is suggested that 90 second rest intervals between sets and exercises promotes a post-exercise hypotensive response in SBP. The 40 second rest interval between sets and exercises was associated with greater cardiac stress, and might be contraindicated when working with individuals that exhibit symptoms of cardiovascular disease.

RESUMO

A 24-year-old Caucasian female patient was referred to our endocrinology service to investigate a structural magnetic resonance imaging (sMRI) finding of "pituitary mass". The first two sMRI were identified as pituitary adenoma but the following two examinations suggested the possibility of pituitary hyperplasia (PH). The patient was referred to our service for diagnostic clarification and therapy due to the divergence in sMRI reports and the surgical procedure indicated by the neurosurgical team of the other institution. The patient had no complaints, laboratory tests were all normal, and the sMRI clearly showed a PH. However, what caught our attention was her behavior. During the interview she was intermittently talking and acting like a child even though her age was 24. She reported being a foster child and was severely mistreated during childhood. Parallel psychiatric evaluation was requested and an association between the PH and the childhood abuse was identified. Early life stress may be associated with accelerated pituitary gland volume development, but there is still a paucity of data in literature about this issue. We should be aware of other cases like this one, and a correct differential diagnosis may contribute to contraindicate transsphenoidal surgery. When a childhood abuse history is present, we recommend admission to a psychiatric facility for adequate treatment.

RESUMO

The purpose of this study was to compare the hypotensive responses of reciprocal supersets (SS) versus traditional training (TRAD) methods. Thirteen men with at least five years of recreational experience in resistance training (RT) volunteered for the study. When completing the TRAD protocol, participants performed the following exercises separately in sequence: chest press (CP), low row (LR), leg extension (LE), leg curl (LC), pull down (PD), and shoulder press (SP). The SS method required participants to complete the same exercises as in the TRAD protocol, but exercises were coupled such that muscles sequentially served both as an agonist for lift one and then antagonist for lift two and vice versa. Exercise order used was CP and LR, LE and LC, and PD and SP with 10 repetition maximum loads. Blood pressure (BP) was measured before and for every 10 minutes for one hour after training. There was significantly more total work (TW) done in the TRAD condition compared to SS. Post exercise hypotension was evident only after the TRAD session at minutes 30 and 40 for systolic BP. Significant differences between the TRAD and SS methods were found at 20 minutes, 30 minutes, and 40 minutes for systolic BP. There was no significant two-way interaction for group × time for diastolic BP. There was a significant two-way interaction for group × time for mean arterial pressure. Significant reductions for mean arterial pressure (MAP) occurred only in the TRAD method after 30 to 40 minutes compared to the baseline values. Therefore, a TRAD RT method was sufficient to cause a hypotensive effect after the training session whereas the SS method did not reveal significant decreases in BP after the session. However, these findings are important to elucidate concerns regarding the post-exercise hypotension after RT and showed that TW might be the key to promote these changes because the volume of training was shown to be an important training variable to manipulate and might be associated with BP hypotension after RT.

RESUMO

Este estudio tuvo como objetivo comparar la respuesta de la presión arterial en los hombres normotensos entrenados realizando sesiones experimentales con cargas del 60 y el 80% de una repetición máxima. Diez participantes se sometieron a 3 condiciones experimentales: P60 (sesión realizada con el 60%); P80 (sesión realizada con el 80% de una repetición máxima [1RM]), y CONT (solo las evaluaciones de la presión arterial en el estado de reposo durante 60 min [intervalos de 10 min]). El protocolo experimental se llevó a cabo con 3 series, con intervalo de 3 min entre las series y los ejercicios. La presión arterial se midió antes y a los 10, 20, 30, 40, 50 y 60 min después de la sesión de entrenamiento. Los resultados mostraron que ambos protocolos indujeron hipotensión postejercicio (p < 0,05) en comparación con los valores en reposo. El P80 mostró una mayor magnitud y duración de la hipotensión postejercicio en comparación con el protocolo P60 (p < 0,05). En conclusión, el entrenamiento de fuerza es eficaz para proporcionar hipotensión postejercicio independientemente de la intensidad de la carga. Por lo tanto, en esta investigación es importante mostrar la relevancia del control de la intensidad de la carga durante el desarrollo de los programas de entrenamiento de fuerza. El entrenamiento de fuerza con el 60% de 1RM puede ser tan eficaz como los protocolos con 80% de 1RM para prevenir la presión arterial alta en los hombres


This study aimed to compare the blood pressure responses in normotensive-trained men following resistance training (RT) experimental sessions with loads of 60% and 80% of a one-repetition maximum. Ten participants underwent three experimental condition: (P60) - session adjusted with 60%, (P80) - session adjusted with 80% of 1 repetition maximum (1RM) and, (CONT) - conly blood pressure assessments in rest condition for 60 min (intervals of 10 min). The resistance training design was adjusted with 3-sets, 3-min rest interval length between sets and exercises. Blood pressure was measured before, and at 10, 20, 30, 40, 50, and 60 min after the training session. The results showed that both protocols induce post-exercise hypotension (p < 0.05) compared to the rest values. The P80 showed greater magnitude and duration of post exercise hypotension when compared with P60 protocol (p < 0.05). In conclusion, resistance training is effective to provide a post exercise hypotension independent of the load intensities. This study is important to show the importance of control of the load intensity during development of resistance training programs and, the RT with 60% of 1RM can be as effective as protocols with 80% of 1RM to prevent the high blood pressure
