Development and Psychometric Properties of Self-Reported Job Interview Skills and Job Interview Anxiety for Autistic Transition-Age Youth.

BACKGROUND: The study of job interview training is an emerging area among transition-age autistic youth who face significant challenges when navigating job interviews. The autism field has limited measures that have undergone rigorous psychometric evaluation. OBJECTIVE: We sought to evaluate the psychometric properties of adapted self-report measures assessing job interview skills and job interview anxiety. METHODS: As part of two parent randomized controlled trials, eighty-five transition-age autistic youth completed measures related to the strength of their job interview skills and their level of job interview anxiety. We conducted classical test theory analyses, exploratory and confirmatory factor analyses, and Rasch model analytic and calibration analyses. Pearson correlations were used to establish concurrent, divergent, and criterion validity by correlating these scales with measures of social differences, depressive symptoms, behaviors, neuropsychological functioning, and work history. RESULTS: Our analyses yielded two brief and reliable scales: Measure of Job Interview Skills (MOJO-iSkills) and Measure of Job Interview Anxiety (MOJO-iAnxiety), which demonstrated initial concurrent, divergent, and criterion validities when correlated with measures of depressive symptoms, social differences, internalizing and externalizing behavior, and work history. CONCLUSIONS: This study presents initial evidence that MOJO-iSkills and MOJO-iAnxiety have acceptable psychometric properties supporting they can be used to reliably and validly assess job interview skills and interview anxiety.

Arousal/Stress Effects of "Overwatch" eSports Game Competition in Collegiate Gamers.

ABSTRACT: Kraemer, WJ, Caldwell, LK, Post, EM, Beeler, MK, Emerson, A, Volek, JS, Maresh, CM, Fogt, JS, Fogt, N, Häkkinen, K, Newton, RU, Lopez, P, Sanchez, BN, and Onate, JA. Arousal/stress effects of "Overwatch" eSports game competition in collegiate gamers. J Strength Cond Res 36(10): 2671-2675, 2022-To date, no physical response data are available for one of the most popular eSport games, Overwatch . The purpose of this investigation was to describe the stress signaling associated with competitive Overwatch play and to understand how acute hormonal responses may affect performance. Thirty-two male college-aged gamers (age: 21.3 ± 2.7 years; estimated time played per week: 18 ± 15 hours) completed the study. Subjects were randomly assigned to a 6-player team to compete in a tournament-style match. Salivary measures of cortisol and testosterone were collected immediately before (PRE) and after (POST) the first-round game, with the heart rate recorded continuously during the match. The mean characteristics were calculated for each variable and comparisons made by the skill level. Significance was defined as p ≤ 0.05. There were no differences in measures of salivary cortisol. A differential response pattern was observed by the skill level for testosterone. The low skill group displayed a significant increase in testosterone with game play (mean ± SD , testosterone PRE: 418.3 ± 89.5 pmol·L -1 , POST: 527.6 ± 132.4 pmol·L -1 , p < 0.001), whereas no change was observed in the high skill group. There were no differences in heart rate characteristics between skill groups. Overall, the average heart rate was 107.2 ± 17.8 bpm with an average max heart rate of 133.3 ± 19.1 bpm. This study provides unique physiological evidence that a sedentary Overwatch match modulates endocrine and cardiovascular responses, with the skill level emerging as a potential modulator.

[Sulfhemoglobinemia secondary to the use of zopiclone. Report of two cases]. / Sulfohemoglobinemia secundaria a zopiclona. Casos clínicos.

Sulfhemoglobin (SulfHb) is formed by hemoglobin (Hb) oxidation by sulfur compounds. Sulfhemoglobinemia is mainly associated with drugs or intestinal bacterial overgrowth. Patients present with central cyanosis, an abnormal pulse oximetry and normal arterial oxygen partial pressure. These features are shared with methemoglobinemia (MetHb) whose diagnosis requires an arterial co-oximetry. Depending on the device used, SulfHb may produce interference with this technique. We report two females aged 31 and 43 years, consulting at the emergency room with cyanosis. Both had a history of acute and chronic, high dose zopiclone ingestion. Pulse oximetry showed desaturation but with normal arterial oxygen partial pressure. Cardiac and pulmonary diseases were ruled out. Co-oximetry in two different analyzers showed interference or normal MetHb percentages. No other complications ensued, and cyanosis decreased over days. Since MetHb was discarded among other causes of cyanosis in a compatible clinical context, the diagnosis of sulfhemoglobinemia was made. The confirmatory method is not available in Chile. The presence of SulfHb is difficult to diagnose, confirmatory tests are not readily available, and it frequently interferes with arterial co-oximetry. This is attributed to a similar absorbance peak of both pigments in arterial blood. Venous co-oximetry can be useful in this context. SulfHb is a self-limited condition in most cases, however it must be differentiated from methemoglobinemia to avoid inappropriate treatments like methylene blue.

Nurses should consider incorporating a mobile tracking component into patient-care settings to promote menstrual health awareness and advocacy and to help create individualized healthcare plans.

Cognition, Depressive Symptoms and Vascular Factors among Southwest Tribal Elders.

OBJECTIVE: Few data exist on cognitive and depressive symptoms and vascular factors in American Indian (AI) elders. Since vascular risk factors increase risk for cognitive impairments, depression and dementia, and since AI elders are at high vascular risk, it is timely to assess the interplay of these factors in comprehensive studies of aging in this population. To begin, pilot studies must be conducted to show these types of data can be collected successfully. DESIGN: A cross-sectional pilot study, the Southwest Heart Mind Study (SHMS). SETTING: Tribal community in the Southwest United States. PARTICIPANTS: AI elders, aged ≥55 years. MAIN OUTCOME MEASURES: Cross-cultural demographic, social network and risk factor surveys; tests of cognition, depression and anxiety; physical measurements; blood biochemistries; and APOE genotyping. RESULTS: SHMS elders were comparable to other rural elder populations on cognitive and depressive symptom scores. The average CogScore was 28.8 (out of 32), the average Geriatric Depression Scale (GDS) was 6.7 (of 30), and the average Hamilton Anxiety Scale was 1.2 (of 4). 32% possessed at least one APOEe4 allele. High vascular risk was evident: 76% were overweight or obese; 54% self-reported history of hypertension; 24% heart trouble; 32% type 2 diabetes; 35% depression; and 24% a family history of serious memory loss. More than 70% reported prescription medication use. 54% cared for someone besides self. CONCLUSIONS: A better understanding of the burden of vascular risk in relation to cognition and depression among Southwest Tribes is needed.

Sex Differences in Energy Metabolism: A Female-Oriented Discussion.

The purpose of this review is to delineate aspects of energy metabolism at rest and during exercise that may be subject to sex differences and the potential underlying mechanisms involved. It focuses on distinct aspects of female physiology with an oriented discussion following the reproductive life stages of healthy, eumenorrheic females, including premenopausal time frames, pregnancy, perimenopause, and menopause. Finally, this review aims to address methodological challenges surrounding sexual dimorphism in energy metabolism investigations and confounding factors in this field. During resting conditions, females tend to have higher rates of non-oxidative free fatty acid clearance, which could contribute to lower respiratory exchange ratio measures. At the same time, carbohydrate energy metabolism findings are mixed. In general, females favor lipid energy metabolism during moderate-intensity exercise, while men favor carbohydrate energy metabolism. Factors such as age, dietary intake, genetics, and methodological decisions confound study findings, including properly identifying and reporting the menstrual cycle phase when female subjects are eumenorrheic. Pregnancy presents a unique shift in physiological systems, including energy metabolism, which can be observed at rest and during exercise. Changes in body composition and hormonal levels during the post-menopausal period directly impact energy metabolism, specifically lipid metabolism. This change in physiological state factors into the evidence showing a reduction in our understanding of sex differences in lipid metabolism during exercise in older adults. This review reveals a need for a focused understanding of female energy metabolism that could help exercise and nutrition professionals optimize female health and performance across the lifespan.

The Spanish Familial Pancreatic Cancer Registry (PANGENFAM): a decade follow-up of individuals at high-risk for pancreatic cancer.

The Spanish Familial Pancreatic Cancer Registry (PANGENFAM) was established in 2009 and aims to characterize the genotype and phenotype of familial pancreatic cancer (FPC). Furthermore, an early detection screening program for pancreatic ductal adenocarcinoma (PDAC) is provided to healthy high-risk individuals from FPC and hereditary pancreatic cancer families (first-degree relatives). This article describes our experience over the last 10 years in high-risk screening. Hereditary and familial pancreatic cancer families were identified through the oncology and gastroenterology units. High-risk individuals underwent annual screening with endoscopic ultrasound (EUS) and magnetic resonance (MRI) from age 40 or 10 years younger than the youngest affected family member. Results: PANGENFAM has enrolled 290 individuals from 143 families, including 52 PDAC cases and 238 high-risk individuals. All high-risk individuals eligible for screening were offered to enter the surveillance program, with 143 currently participating. Pancreatic abnormalities were detected in 94 individuals (median age 53 years (29-83), with common findings including cystic lesions and inhomogeneous parenchyma. Imaging test concordance was 66%. Surgical intervention was performed in 4 high-risk individuals following highly suspicious lesions detected by imaging. PANGENFAM is a valuable resource for science innovation, such as biobanking, with clinical and imaging data available for analysis. For high-risk families, it may offer a potential for early diagnosis. Collaboration with other national and international registries is needed to increase our understanding of the disease biology and to standardize criteria for inclusion and follow-up, optimizing cost-effectiveness and efficacy.

Hepatitis E virus in Cuba: A cross-sectional serological and virological study in pigs and people occupationally exposed to pigs.

Surveillance of hepatitis E virus (HEV) in risk groups is an important strategy to monitor its circulation pattern and to timely detect changes thereof. The aims of this cross-sectional study were to estimate the prevalence of HEV infections in pigs and humans from different regions of the country, to identify risk factors for increasing anti-HEV IgG prevalence and to characterize HEV strains. The presence of anti-HEV antibodies was assessed by commercial ELISA in serum samples from the general population, farm and slaughterhouse employees, as well as pigs sampled in the three regions of Cuba from February to September 2016. Overall, individuals with occupational exposure to swine or swine products (70/248, 28.2%) were 4 times more likely to be seropositive compared to the general population (25/285, 8.7%; OR: 4.18; p < .001). Within the risk group, risk factors included age, number of years working in a professional activity with direct exposure to swine, geographic region and distance between residence and closest professional swine setting, while wearing gloves had a protective effect. Prevalence of total anti-HEV antibodies in swine was 88.2% (165/187) and HEV RNA was detected by real-time RT-PCR in 9.2% (16/173) swine stools. All HEV strains sequenced clustered within genotype 3. Some strains clearly belonged to subtype 3a, while another group of strains was related with subtypes 3b and 3 k but partial HEV sequences did not allow unequivocal subtype assignment. These findings suggest that the high HEV exposure in Cuban individuals with swine-related occupations could be due to enzootic HEV in certain regions, direct contact with infectious animals or their products as well as environmental contamination.

Psychometric properties of the mock interview rating scale for autistic transition-age youth.

Background: Employment is a major contributor to quality of life. However, autistic people are often unemployed and underemployed. One potential barrier to employment is the job interview. However, the availability of psychometrically-evaluated assessments of job interviewing skills is limited for autism services providers and researchers. Objective: We analyzed the psychometric properties of the Mock Interview Rating Scale that was adapted for research with autistic transition-age youth (A-MIRS; a comprehensive assessment of video-recorded job interview role-play scenarios using anchor-based ratings for 14 scripted job scenarios). Methods: Eighty-five transition-age youth with autism completed one of two randomized controlled trials to test the effectiveness of two interventions focused on job interview skills. All participants completed a single job interview role-play at pre-test that was scored by raters using the A-MIRS. We analyzed the structure of the A-MIRS using classical test theory, which involved conducting both exploratory and confirmatory factor analyzes, Rasch model analysis and calibration techniques. We then assessed internal consistency, inter-rater reliability, and test-retest reliability. Pearson correlations were used to assess the A-MIRS' construct, convergent, divergent, criterion, and predictive validities by comparing it to demographic, clinical, cognitive, work history measures, and employment outcomes. Results: Results revealed an 11-item unidimensional construct with strong internal consistency, inter-rater reliability, and test-retest reliability. Construct [pragmatic social skills (r = 0.61, p < 0.001), self-reported interview skills (r = 0.34, p = 0.001)], divergent [e.g., age (r = -0.13, p = 0.26), race (r = 0.02, p = 0.87)], and predictive validities [competitive employment (r = 0.31, p = 0.03)] received initial support via study correlations, while convergent [e.g., intrinsic motivation (r = 0.32, p = 0.007), job interview anxiety (r = -0.19, p = 0.08)] and criterion [e.g., prior employment (r = 0.22, p = 0.046), current employment (r = 0.21, p = 0.054)] validities were limited. Conclusion: The psychometric properties of the 11-item A-MIRS ranged from strong-to-acceptable, indicating it may have utility as a reliable and valid method for assessing the job interview skills of autistic transition-age youth.

Establishment of Pancreatic Cancer-Derived Tumor Organoids and Fibroblasts From Fresh Tissue.

Tumor organoids are three-dimensional (3D) ex vivo tumor models that recapitulate the biological key features of the original primary tumor tissues. Patient-derived tumor organoids have been used in translational cancer research and can be applied to assess treatment sensitivity and resistance, cell-cell interactions, and tumor cell interactions with the tumor microenvironment. Tumor organoids are complex culture systems that require advanced cell culture techniques and culture media with specific growth factor cocktails and a biological basement membrane that mimics the extracellular environment. The ability to establish primary tumor cultures highly depends on the tissue of origin, the cellularity, and the clinical features of the tumor, such as the tumor grade. Furthermore, tissue sample collection, material quality and quantity, as well as correct biobanking and storage are crucial elements of this procedure. The technical capabilities of the laboratory are also crucial factors to consider. Here, we report a validated SOP/protocol that is technically and economically feasible for the culture of ex vivo tumor organoids from fresh tissue samples of pancreatic adenocarcinoma origin, either from fresh primary resected patient donor tissue or patient-derived xenografts (PDX). The technique described herein can be performed in laboratories with basic tissue culture and mouse facilities and is tailored for wide application in the translational oncology field.

Low prevalence of hepatitis delta infection in Cuban HBsAg carriers: Prospect for elimination.

Introduction: Infection with hepatitis delta virus (HDV) is one of the most severe hepatitis B virus (HBV) complications, with a more rapid progression to cirrhosis and an increased risk of hepatic decompensation and death. Data on HDV infection in Cuba are limited. The aims of our study were to determine the HDV prevalence in HBsAg carriers and to characterize the HDV strains circulating. The data were used to assess the possibility of HDV elimination in the Cuban HBV epidemiological setting. Methods: Five hundred and two serum samples from the same number of HBsAg carriers collected in the period 2006-2019 from all over the country were tested for anti-HDV total antibodies. If positive, the samples were analyzed for HDV-RNA using Real-Time RT-PCR targeting the ribozyme and HD antigen domains followed by genotyping based on phylogenetic analysis. Results: Two samples were anti-HDV positive [0.39% (95% CI 0.11-1.44)]. One of them was also HDV-RNA positive. Clinically, the patient with active HDV infection had compensated liver cirrhosis. Phylogenetic analysis showed that the virus belonged to genotype 1 and thus clustered with contemporary strains from North America, Europe, Middle East, and Asia. Discussion: This is the first HDV study, including molecular detection and virus characterization, done after the introduction of the universal childhood anti-hepatitis B vaccination. The very low prevalence of HDV infection in HBsAg carriers combined with the high HBV vaccination coverage of all newborn children, of previously identified risk groups, and of the general population currently under 40 years of age suggests that HDV elimination is feasible in Cuba if the success in HBV control is maintained.

The Effects of Resistance Training on Physical Fitness and Neuromotor-Cognitive Functions in Adults With Down Syndrome.

Adults with Down syndrome are an underserved population at high risk for a host of different pathologies from aging and lack of activity. Purpose: To examine the effects of a 10-week resistance training program on measures of motor behavior, cognitive function, mood, and physical fitness. Methods: Participants (n = 11) were men and women clinically diagnosed with Down syndrome (age: 25.8 ± 6.4 years; height: 151.5 ± 8.3 cm; weight: 67.5 ± 13.0 kg; IQ: 58.3 ± 19.7 units). After familiarization of testing procedures, subjects performed The Arizona Cognitive Test Battery for Down Syndrome, TGMD-2, lower and upper body strength assessments, and body composition via DXA testing, while parental guardians completed cognitive and mood survey assessments (Cognitive Scale for Down Syndrome, Behavioral Rating Inventory of Executive Function, NiSonger Child Behavior Rating Form, Scales of Independent Behavior-Revised, Child Eating Behavior Questionnaire, Social Communication Questionnaire, and Mood and Feelings Questionnaire) at pre and post 10 weeks of periodized resistance training. Results: Significant (P ≤ 0.05) improvements in locomotor skills and object control skills were observed post-training. Both locomotor skills (e.g., sprint, gallop, leaping, broad jump) and object control skills (e.g., baseball catch, underhand roll, basketball dribble) were all significantly improved. Facets of cognitive performance significantly improved, specifically executive function and visuospatial working memory capacity, and frontal lobe activity. Mood disturbances significantly decrease. All aspects of physical strength and endurance were improved, i.e., leg press, bench press, sit-ups, push-ups, and chair sit-to-stand post-training. Lean tissue mass was significantly increased post-training. Conclusion: This study dramatically demonstrates that life enhancements for individuals with Down syndrome are achievable with a properly designed resistance training program.

Ostectomy versus osteotomy with repositioning of the vestibular cortical in periapical surgery of mandibular molars: a preliminary study.

INTRODUCTION: Accessing the tooth roots in periapical surgery (PS) requires the elimination of periapical bone. OBJECTIVE: To compare the postoperative morbidity and prognosis following PS on mandibular molars by ostectomy, or by osteotomy with repositioning of the vestibular cortical. MATERIAL AND METHODS: A retrospective clinical study of mandibular molars subjected to PS with ultrasound. Two groups were considered according to the surgical procedure used to access the roots: Group 1 (G1) with ostectomy and Group 2 (G2) with osteotomy and repositioning of the vestibular cortical. Only patients who had properly followed the post-operative instructions, adequately completed the post-operative questionnaires, and with a minimum of 12 months follow-up were included in the study. Post-operative morbidity was evaluated, and a clinical and radiographic follow-up was carried out using the criteria established by von Arx and Kurt in 1999. The SPSS program version 15 for Windows was used, considering values of p < or =0.05 as statistically significant. RESULTS: Seventy-five patients, including 18 men and 57 women, with 87 mandibular molars and 107 periapical lesions were subjected to PS. The mean age of the patients was 38.5 years old (range 15-74 years old). The patients were monitored for an average of 27.2 months (range 12-120 months). Sixty-six patients (78 teeth) were treated in G1, and 9 patients (9 teeth) in G2. There was no relationship between the size of the ostectomy and pain, swelling or prognosis (p>0.05). Patients who underwent ostectomy presented more swelling than those subjected to osteotomy (p<0.05). There was no relationship between prognosis and the variables studied (p>0.05). CONCLUSIONS: There was no statistically significant relationship between the surgical procedure used and post-operative pain or prognosis. Patients who underwent an ostectomy presented more swelling than those who were treated with an osteotomy and repositioning of the vestibular cortical.

Radiographic morphometric study of 37 periapical lesions in 30 patients: validation of success criteria.

PURPOSE: The purpose of this study was to establish the midterm prognosis of periapical surgery by use of the ultrasound technique, comparing a scale obtained by image analysis with the success rates according to other prognostic scales. MATERIALS AND METHODS: A clinical follow-up study was performed between September 2004 and September 2005. Thirty-six patients with chronic periapical lesions were treated with periapical surgery via the ultrasound technique and root-end filling with silver amalgam. Evolution was analyzed by use of the different currently accepted assessment scales at 6 and 12 months after intervention with a scale obtained by radiographic image analysis. RESULTS: Thirty patients with a mean age of 40.5 years were studied. The mean follow-up period was 14.2 months. Thirty-seven lesions were analyzed. A positive correlation at 6 months was observed between the radiographic scale proposed in this study and the scales of Rud and Andreasen and von Arx et al. At 12 months, the proposed radiographic scale only correlated with the functional tooth concept established by Friedman. CONCLUSIONS: There was no statistically significant relation between the radiographic scale from the image analyzer and the criteria of Rud and Andreasen and von Arx et al.

Can emotional intelligence be improved? A randomized experimental study of a business-oriented EI training program for senior managers.

PURPOSE: This article presents the results of a training program in emotional intelligence. DESIGN/METHODOLOGY/APPROACH: Emotional Intelligence (EI) involves two important competencies: (1) the ability to recognize feelings and emotions in oneself and others, and (2) the ability to use that information to resolve conflicts and problems to improve interactions with others. We provided a 30-hour Training Course on Emotional Intelligence (TCEI) for 54 senior managers of a private company. A pretest-posttest design with a control group was adopted. FINDINGS: EI assessed using mixed and ability-based measures can be improved after training. ORIGINALITY/VALUE: The study's results revealed that EI can be improved within business environments. Results and implications of including EI training in professional development plans for private organizations are discussed.

Evaluation of healing criteria for success after periapical surgery.

INTRODUCTION: In periapical surgery, the absence of standardization between different studies makes it difficult to compare the outcomes. OBJECTIVE: To compare the healing classification of different authors and evaluate the prognostic criteria of periapical surgery at 12 months. MATERIAL AND METHODS: 278 patients (101 men and 177 women) with a mean age of 38.1 years (range 11 to 77) treated with periapical surgery using the ultrasound technique and a 2.6x magnifying glass, and silver amalgam as root-end filling material were included in the study. Evolution was analyzed using the clinical criteria of Mikkonen et al., 1983; radiographic criteria of Rud et al., 1972; the overall combined clinical and radiographic criteria of von Arx and Kurt, 1999; and the Friedman (2005) concept of functional tooth at 12 months of surgery. RESULTS: After 12 months, 87.2% clinical success was obtained according to the Mikkonen et al., 1983 criteria; 73.9% complete radiographic healing using Rud et al. criteria; 62.1% overall success, following the clinical and radiographic parameters of von Arx and Kurt, and 91.9% of teeth were functional. The von Arx and Kurt criteria was found to be the most reliable. CONCLUSION: Overall evolution according to von Arx and Kurt agreed most closely with the other scales.

Can Emotional Competence Be Taught in Higher Education? A Randomized Experimental Study of an Emotional Intelligence Training Program Using a Multimethodological Approach.

Since the introduction of the Bologna Process, the goal of education has been not only to acquire technical skills but also to master other skills, such as teamwork, effective communication skills, time optimization, and the ability to manage one's emotions. The present work describes a program to develop emotional intelligence in higher education, the "Emotional Intelligence Training Program," with a multimethodological approach that offers the opportunity for university students to develop their emotional intelligence. A total of 192 higher education students participated in this educational experience. Of the participants, 66% were women, and 34% were men; the average age of the sample was 18.83 years with a standard deviation of 2.73. The results indicate that our program can help improve emotional intelligence through three proposed methodologies: online, in the classroom, and coaching. It has been demonstrated that the program is effective in the three methodological modalities presented, offering a range of possibilities to future users because it is possible to select the most appropriate modality based on the resources and possibilities available in each situation. Finally, Future research should focus on the application of this program to assess the acquisition of emotional competences at the postgraduate level.

Emotional intelligence training intervention among trainee teachers: a quasi-experimental study.

BACKGROUND: Emotional intelligence (EI) has often been linked to improvements in professional performance. Indeed, generic competencies related to EI have been included in university curricula. However, learning EI involves significant time and effort on the part of students, and this may hinder the acquisition of specific content for each degree. In this study, an intervention to develop EI in higher education students is described and evaluated. METHODS: The intervention consisted of eight group sessions performed in a regular course aiming to increase EI. The sessions included strategies and training on perceiving and understanding one's own emotions and others' emotions, identifying and understanding the impact one's own feelings in adopting decisions, expressing one's own emotions and the stress experienced, and managing both one's own emotions and emotions of others. Participants were 192 students studying for a Master of Primary Education degree. A quasi-experimental nonequivalent control group pretest-posttest design was adopted. The effectiveness of the intervention was evaluated using multi-level analyses. RESULTS: The results showed a significant improvement in the EI of students in the experimental group compared with the control group. CONCLUSIONS: This research demonstrates that it is possible to develop EI in higher education students, without hindering the acquisition of specific content competencies and, therefore, without interfering with their academic performance and without overburdening students with work outside the classroom. TRIAL REGISTRATION: The experiment has been registered in the Initial Deposit of the Spanish Center for Sociological Research (CIS). 7/6/2015. http://www.cis.es/cis/opencms/ES/index.html .

Técnicas fisioterapéuticas de entrenamiento muscular inspiratorio y Buteyko en niños con asma bronquial / Inspiratory and Buteyko muscular training physiotherapeutic techniques in children with bronchial asthma

El asma bronquial es una enfermedad respiratoria crónica que genera elevados índices de discapacidad, sobre todo en la población infantil. La aplicación de fisioterapia respiratoria constituye un coadyuvante en los esquemas terapéuticos de la enfermedad; en este sentido el entrenamiento muscular inspiratorio y el método Buteyko constituyen técnicas respiratorias que han sido reportadas como útiles en el tratamiento del asma bronquial. La presente investigación tuvo como objetivo describir las ventajas que ofrecen ambos métodos como esquemas terapéuticos de niños con asma bronquial. Como principales resultados se describen una serie de estudios que muestran las ventajas de la implementación de estos métodos para mejorar distintos componentes de la patogenia y manifestaciones clínicas del asma bronquial. Estos estudios muestran que la aplicación indistinta de uno o ambos métodos mejora diversos aspectos entre los que sobresalen mejorar volúmenes y capacidades pulmonares, función pulmonar, fuerza muscular ventilatoria y la mecánica respiratoria. Adicionalmente, mejoran algunos elementos relacionados con la mecánica respiratoria como es el uso de la respiración bucal. Se concluye que la realización de la fisioterapia respiratoria en niños con asma bronquial constituye una alternativa viable y eficaz en el mejoramiento de varios parámetros relacionados con esta enfermedad. Diversos estudios demuestran que la aplicación de estas técnicas respiratorias mejora la capacidad respiratoria, el tono y trofismo de músculos respiratorios y la mecánica respiratoria. Los resultados positivos evidencian la necesidad de aumentar la implementación del entrenamiento muscular inspiratorio y el método Buteyko como esquema terapéutico en niños con asma bronquial en unidades de atención pública y privada(AU)

Bronchial asthma is a chronic respiratory disease that generates high rates of disability, especially in children. The application of respiratory physiotherapy constitutes an adjunct in the therapeutic schemes of the disease; in this sense, inspiratory muscle training and the Buteyko method constitute respiratory techniques that have been reported as useful in the treatment of bronchial asthma. The present investigation aimed to describe the advantages offered by both methods as therapeutic regimens for children with bronchial asthma. The main results are a series of studies that show the advantages of the implementation of these methods to improve different components of the etiopathogenesis and clinical manifestations of bronchial asthma. These studies show that the indistinct application of one or both methods improves different aspects, among which the improvement of lung volumes and capacities, lung function, ventilatory muscle strength and respiratory mechanics stand out. Additionally, they improve some elements related to respiratory mechanics such as the use of mouth breathing. It is concluded that the performance of respiratory physiotherapy in children with bronchial asthma constitutes a viable and effective alternative in the improvement of various parameters related to this disease. Several studies show that the use of these respiratory techniques improves respiratory capacity, tone and trophism of respiratory muscles, and respiratory mechanics. The positive results demonstrate the need to increase the implementation of inspiratory muscle training and the Buteyko method as a therapeutic scheme in children with bronchial asthma in public and private care units(AU)
