RESUMO

Measurement of oxyhemoglobin (O2Hb) changes in the cerebral cortex using near-infrared spectroscopy (NIRS) shows that its levels increase during moderate-intensity exercise and persists after exercise. However, the effects of exercise duration on O2Hb persistence in the premotor cortex (PMC) are unknown. We aimed to determine the effects of exercise duration on the persistence of O2Hb changes after moderate-intensity cycling as exercise. Healthy young volunteers were recruited to participate in this study. After a 3-min rest period, the exercise was initiated at a workload corresponding to 50% VO2peak. The exercise continued for 10 min and 20 min, followed by 15 min of rest. The O2Hb levels in the right (R-PMC) and left premotor cortices (L-PMC) were measured using an NIRS system. The O2Hb values during the 15-min post-exercise rest period in the R-PMC were 0.010 ± 0.011 mM·cm after the 10-min exercise and 0.035 ± 0.010 mM·cm after the 20-min exercise, without significant differences (p = 0.104). The O2Hb value in the L-PMC during post-exercise rest (0.055 ± 0.010 mM·cm) after the 20-min exercise was significantly higher than that after the 10-min exercise (0.023 ± 0.007 mM·cm; p = 0.014). Thus, the effects of exercise duration on O2Hb persistence have laterality in the PMC.

RESUMO

Our previous research confirmed that patients with malignant hematopoietic disease already had a low hemoglobin level before allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, no study has determined whether a correlation exists between exercise load, hemoglobin level, and muscle oxygen saturation (SmO2), during exercise. Therefore, the purpose of this study was to investigate whether near-infrared spectroscopy (NIRS)-derived SmO2 is associated with exercise load, as determined by a dynamometer, before allo-HSCT. This study included 19 male patients who received allo-HSCT in Hyogo College of Medicine Hospital (Japan) between November 2009 and October 2012. Patients performed isometric repeated dorsiflexion at 50% maximum voluntary contraction for 180 s to determine exercise load, and SmO2 was evaluated during exercise at the same time using NIRS (BOM-L1TRW, Omega Wave, Inc., Japan). The hemoglobin level was also evaluated before allo-HSCT. Patients with hematopoietic disease before allo-HSCT already had a low hemoglobin level. There was a significant correlation between exercise load and ∆SmO2; however, the hemoglobin level was not correlated with exercise load. In these patients, exercise load might be affected by muscle oxygen consumption rather than by the hemoglobin level. This finding shows that NIRS can used to assess fatigue in patients with malignant hematopoietic disease.

RESUMO

Cognitive function is reported to improve by moderate aerobic exercise. However, the effects of intermittent exercise with rest between the moderate-intensity exercise are unclear. Therefore, this study aimed to compare the effects of continuous and intermittent exercise on cerebral oxygenation and cognitive function. This study included 18 healthy adults. For the continuous exercise protocol, 5 min of rest was followed by 30 min of exercise; 5 min of rest was allowed after each exercise. For the intermittent exercise protocol, 3 sets of 10 min of exercise were completed, with 5 min of rest between the sets. Exercise intensity was 50% of maximum oxygen uptake. Oxyhemoglobin (O2Hb) in the prefrontal cortex (PFC) was measured during each protocol, and cognitive tasks (Stroop test) were performed before and after exercise. O2Hb levels for the left and right PFCs were significantly higher post-exercise than pre-exercise for both exercise protocols (p < 0.01). The average reaction time in the Stroop test was significantly shorter post-exercise than pre-exercise for both protocols (p < 0.01). There was no significant difference in the error rate pre- and post-exercise for both protocols (continuous p = 0.22; intermittent p = 0.44). There was no significant difference between both protocols in all measurement results (O2Hb: p = 0.67; average reaction time p = 0.50; error rate p = 0.24). O2Hb was higher and average reaction time was shorter after exercise than before exercise for both exercise protocols. Intermittent and continuous exercise may improve cognitive function to the same degree after exercise.

RESUMO

The aim of this study was to compare muscle O2 dynamics during exercise between aerobic capacity-matched overweight and normal-weight adults. Overweight women (OW, n = 9) and normal-weight women (NW, n = 14) performed graded treadmill exercise until exhaustion. Muscle O2 saturation (SmO2) and relative changes from rest in deoxygenated hemoglobin concentration (∆deoxy-Hb) and total hemoglobin concentration (∆total-Hb) were monitored continuously at gastrocnemius medialis muscle by near infrared spatial resolved spectroscopy. Significantly higher SmO2 and lower ∆deoxy-Hb and ∆total-Hb were observed in OW compared with NW. Pulmonary O2 uptake (VO2) normalized by fat-free mass was matched between groups. In both groups, peak VO2 was significantly correlated with change in SmO2 and ∆deoxy-Hb. Our findings suggest that both muscle blood volume and deoxygenation were lower in overweight adults, compared to aerobic capacity-matched normal-weight adults. Moreover, lowered muscle O2 extraction was related to peak VO2 in overweight adults, as well as in normal-weight adults.

RESUMO

Near-infrared time-resolved spectroscopy (NIRTRS) can quantitatively evaluate mean optical path length (MPL). Since an increase in optical absorbers in the NIR region (e.g. an increase in deoxygenated hemoglobin during exercise) would shorten the MPL, the NIRS measurement area may vary depending on physical and physiological characteristics of the measurement region and/or the exercise intensity. The aim of this study was to examine the changes in MPL measured by NIRTRS during ramp cycling exercise between fat layer thickness-matched subjects with different aerobic capacities. Healthy control (CON, n = 8) and endurance-trained males (TR, n = 8) performed ramp cycling exercise until exhaustion. Deoxygenated hemoglobin concentration (Deoxy-Hb), total hemoglobin concentration (Total-Hb) and oxygenated hemoglobin concentration (Oxy-Hb) were evaluated by a three-wavelength NIRTRS system. MPL in each wavelength (MPL760, MPL800 and MPL830) was monitored continuously. With increasing exercise intensity, Total- and Deoxy-Hb significantly increased and Oxy-Hb decreased in both groups. Total- and Oxy-Hb during exercise were significantly higher in TR than CON (P < 0.05, P < 0.01, respectively). Furthermore, Deoxy-Hb also tended to be higher in TR than CON (P = 0.07). In addition, MPL at all wavelengths significantly shortened with an increase in exercise intensity, with no differences between CON and TR. In particular, MPL760 at peak exercise shortened more than 10% compared to the start of exercise in both groups, even though MPL830 decreased only a few per cent. These findings suggest that the NIRS measurement area may be reduced during ramp cycling exercise due to shortened MPL. Additionally, the changes in MPL may be especially greater at 760 nm than at the other wavelengths due to greater changes in Deoxy-Hb during exercise. Furthermore, this study indicates that the measurements of muscle deoxygenation using continuous-wave NIRS can be less accurate since they are significantly affected by changes in the optical path length.

RESUMO

The aim of this study was to conduct a systematic review to determine the quality of evidence of studies assessing isokinetic hip muscle strength in adult non-injured individuals. We also aimed to summarise and pool data of normative values for hip muscle strength. The influence of methodological and participant-related factors on hip strength performance was explored as well. Guidelines proposed in the PRISMA were used to undertake a search strategy involving the keyword 'hip' associated with a set of keywords reflecting muscle strength. Five databases were searched: ProQuest, PubMed, Science Direct, Scopus and Web of Science. From the 2,939 records initially retained, 28 articles were included in this systematic review. Eight articles were classified as high quality. This systematic review exposed the methodological fragility of most studies assessing hip strength in non-injured adult population. Only data from studies with a small number of participants are available to be used as reference. A few individual studies suggest no differences in torque parameters between dominant and non-dominant lower limbs; differences in torque parameters between age groups; and between male and female participants. Overall, reference values for hip muscle performance in isokinetic tests are mostly unclear.

RESUMO

Antecedentes: El ejercicio intervalado de alta intensidad (HIIT) ha sido utilizado ampliamente para combatir los factores de riesgo cardiovascular en población adolescente y adulta, existiendo un vacío de su aplicabilidad en población infantil. Objetivos: Determinar los efectos de un HIIT sobre distintos parámetros antropométricos y cardiovasculares de niños con sobrepeso y obesidad de entre 7 y 9 años de edad. Material y métodos: Cuatro grupos fueron formados: 1) grupo control con sobrepeso (GCS, n = 30, IMC = 21,60 ± 3,72 kg/m2); 2) grupo control con obesidad (GCO, n = 34, IMC = 23,92 ± 3,11 kg/m2); 3) grupo intervención con sobrepeso (GIS, n = 69, IMC = 20,01 ± 1,88 kg/m2), y 4) grupo intervención con obesidad (GIO, n = 141, IMC=24,12 ± 2,66 kg/m2). El IMC, grasa corporal (GC), circunferencia de cintura, razón cintura-estatura, presión arterial sistólica y diastólica, y capacidad cardiorrespiratoria (CRF), fueron evaluadas pre- y postintervención. Resultados: Existieron diferencias significativas en las variables IMC (p < 0,001), GC (p < 0,001) y CRF (p < 0,001) en la comparación entre grupos (control vs. intervención) en pre- y postintervención (GCS vs. GIS y GCO vs. GIO). El GIS (IMC; pre = 20,01 ± 1,88 vs. post = 19,00 ± 2,02, p < 0,001) y el GIO (IMC; pre = 24,12 ± 2,66 vs. post = 23,23 ± 3,23, p < 0,001) disminuyeron su IMC. De igual forma, en el GIS (GC; pre = 21,84 ± 4,97 vs. post = 19,55±4,81%, p < 0,001) y en el GIO (GC; pre = 30,26 ± 11,49 vs. post =26,81 ± 6,80%, p < 0,001) la GC disminuyó. Ambos grupos intervenidos mejoraron su CRF (p < 0,001). Existió una disminución significativa de escolares con obesidad (pre = 66,4% vs. post = 49,6%) (p < 0,001). Conclusión: La intervención realizada en el contexto escolar mejora los parámetros antropométricos y cardiovasculares de los escolares, permitiendo además disminuir la proporción de escolares con obesidad


Background: High-intensity interval training (HIIT) has been widely used to fight cardiovascular risk factors in adolescents and adults, but no data are available on its applicability in children. Objectives: To assess the effects of HIIT on different anthropometric and cardiovascular parameters of overweight and obese children aged 7-9 years. Material and methods: Four groups were formed: 1) an overweight control group (OWCG, n = 30, BMI = 21.60 ± 3.72 kg/m2); 2) an obesity control group (OCG, n = 34, BMI = 23.92 ± 3.11 kg/m2); 3) an overweight intervention group (OWIG, n = 69, BMI = 20.01 ± 1.88 kg/m2), and 4) an obesity intervention group (OIG, n = 141, BMI = 24.12 ± 2.66 kg/m2). BMI, body fat (BF), waist circumference, height-waist ratio, systolic and diastolic blood pressure and cardiorespiratory fitness (CRF) were assessed before and after intervention. Results: There were significant differences in BMI (P < .001), BF (P < .001), and CRF (P < .001) between the groups (control vs. intervention) before and after intervention (OWCG vs. OWIG and OCG vs. OIG). BMI decreased in the OWIG (BMI, 20.01 ± 1.88 at baseline vs. 19.00 ± 2.02 after HIIT, P < .001) and OIG (BMI, 24.12 ± 2.66 at baseline vs. 23.23 ± 3.23 after HIIT, P < .001) groups. Similarly, BF decreased in the OWIG (BF, 21.84 ± 4.97 at baseline vs. 19.55 ± 4.81% after HIIT, P < .001) and OIG (BF, 30.26 ± 11.49 at baseline vs. 26.81 ± 6.80% after HIIT, P < .001) groups. CRF improved in both intervention groups (P < .001). There was a significant decrease in the prevalence rate of schoolchildren with obesity (from 66.4% to 49.6%) (P < .001). Conclusion: The intervention conducted in the school setting improved the anthropometric and cardiovascular parameters of schoolchildren, and also allowed for reducing the proportion of schoolchildren with obesity

RESUMO

Background: Studies trying to find the association between vitamin D status and metabolic syndrome (MetS) have led to inconsistent results, and community-based data for individuals living in the Middle East are limited. Objectives: To find out if MetS and its components are associated with vitamin D status among female teachers residing in Yazd city during winter 2015. Materials and methods: A total of 276 female teachers (case group, n = 124 and control group, n = 152) aged 20-60 years were included. Weight, height, waist circumference, blood pressure, daily energy intake, physical activity, serum 25 hydroxy vitamin D (25(OH)D3), fasting blood glucose, triglycerides and high-density lipoprotein cholesterol (HDL-C) levels were assessed. Logistic regression was used to examine the odds ratio of MetS according to vitamin D status. Results: Mean serum 25(OH)D3 was 32.79 ± 18.62 ng/ml and 33.73 ± 20.20, in females with and without MetS, respectively (P > 0.142). Compared to those with 25(OH)D3of < 20 ng/ml, the odds ratio for MetS was 1.01 (95% CI: 0.48-2.13) and 0.95 (95% CI: 0.56-1.60) for those with serum 25(OH)D3 levels of 20-29 ng/ml and ≥ 30 ng/ml, respectively (P trend = 0.84). The association remained insignificant after adjusting for potential confounders. Furthermore, vitamin D status was not associated with MetS components (P > 0.05). Conclusion: Although several studies have claimed the association between vitamin D status and MetS, we could not find a similar connection in a sample of Iranian female teachers. Prospective studies are needed to determine the possible effect of vitamin D in the development of MetS, particularly in the Yazd province


Antecedentes: Los estudios en busca de una asociación entre el estado de vitamina D y el síndrome metabólico (SM) han dado resultados no concluyentes, y los datos sobre comunidades de personas residentes en Oriente Próximo son limitados. Objetivos: Averiguar si existe asociación entre el SM y sus componentes y el estado de vitamina D en profesoras residentes en la ciudad de Yazd durante el invierno de 2015. Materiales y métodos: Se incluyó a un total de 276 profesoras (grupos de casos, n = 124 y grupo de control, n = 152) de 20-60 años de edad. Se determinaron el peso, la talla, el perímetro de la cintura, la presión arterial, la ingesta diaria de energía, la actividad física y los niveles de 25-hidroxivitamina D (25(OH)D3), glucosa en ayunas, triglicéridos y colesterol de las proteínas de alta densidad (C-HDL). Se utilizó regresión logística para determinar la razón de probabilidades de SM en función del estado de vitamina D. Resultados: La concentración sérica media de 25(OH)D3 era de 32,79 ± 18,62 ng/ml y 33,73 ± 20,20 en las mujeres con y sin SM, respectivamente (P > 0,142). En comparación con las que tenían < 20 ng/ml de 25(OH)D3, la razón de probabilidades de SM era 1,01 (IC al 95%, 0,48-2,13) y 0,95 (IC al 95%, 0,56-1,60) en las que tenían valores de 20-29 ng/ml y ≥ 30 ng/ml, respectivamente (tendencia de P = 0,84). La asociación seguía siendo no significativa después del ajuste por posibles factores de confusión. Además, el estado de vitamina D no se asociaba con los componentes del SM (P > 0,05). Conclusión: Aunque varios estudios han informado de una asociación entre el estado de la vitamina D y el SM, no pudimos hallar una relación similar en una muestra de profesoras iraníes. Se necesitan estudios prospectivos para determinar el posible efecto de la vitamina D en el desarrollo del SM, especialmente en la provincia de Yazd

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. PCOS has a significant negative impact on the health-related quality of life (HRQoL) and psychological function of women, of which there are reports of high levels of depression in women with PCOS compared to those without PCOS. However, the evidence surrounding the effects of exercise and/or dietary intervention participation on the HRQoL of women with PCOS is limited. Therefore, our objective is to examine the effects of lifestyle interventions (definition include exercise-only, diet-only, exercise + diet and behavioral or combined) on health-related quality of life or general quality of life in women with PCOS. METHODS: We will conduct an update of systematic review and we will follow the recommendations and guidelines of the Cochrane handbook for systematic reviews and Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol (PRISMA-P). We will search the studies in the following databases: MEDLINE. PubMed, PsychINFO, Embase, SportDiscus, Web of Science, Cochrane Database (via Cochrane library), Cochrane Controlled Register of Trials (CENTRAL), and Google Scholar (advance). Manual search of the reference list of identified works, without language and year restrictions. The process of study selection and data extraction will be performed independently by 2 reviewers, with a third reviewer being responsible for the final decision in case of disagreement between the first two. We will use Egger funnel chart to evaluate possible publication biases, in addition, when possible we will perform a subgroup/meta-regression analysis. The strength of the evidence will be assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). PROTOCOL REGISTRY: PROSPERO number: CRD42019124176.

RESUMO

OBJECTIVE: To explore associations between different frequencies of arts engagement and mortality over a 14 year follow-up period. DESIGN: Prospective cohort study. PARTICIPANTS: English Longitudinal Study of Ageing cohort of 6710 community dwelling adults aged 50 years and older (53.6% women, average age 65.9 years, standard deviation 9.4) who provided baseline data in 2004-05. INTERVENTION: Self reported receptive arts engagement (going to museums, art galleries, exhibitions, the theatre, concerts, or the opera). MEASUREMENT: Mortality measured through data linkage to the National Health Service central register. RESULTS: People who engaged with receptive arts activities on an infrequent basis (once or twice a year) had a 14% lower risk of dying at any point during the follow-up (809/3042 deaths, hazard ratio 0.86, 95% confidence interval 0.77 to 0.96) compared with those who never engaged (837/1762 deaths). People who engaged with receptive arts activities on a frequent basis (every few months or more) had a 31% lower risk of dying (355/1906 deaths, 0.69, 0.59 to 0.80), independent of demographic, socioeconomic, health related, behavioural, and social factors. Results were robust to a range of sensitivity analyses with no evidence of moderation by sex, socioeconomic status, or social factors. This study was observational and so causality cannot be assumed. CONCLUSIONS: Receptive arts engagement could have a protective association with longevity in older adults. This association might be partly explained by differences in cognition, mental health, and physical activity among those who do and do not engage in the arts, but remains even when the model is adjusted for these factors.

RESUMO

OBJECTIVE: To determine the implications of car ownership for physical activity and weight in a global city. DESIGN: Quasi-experimental cross sectional study. SETTING: Beijing, China, 2011-15. PARTICIPANTS: People aged 18 and older from a random sample of households who had entered a permit lottery to purchase a vehicle between January 2011 and November 2015. INTERVENTIONS: Permit allowing purchase of a vehicle within six months of permit issuance. MAIN OUTCOME MEASURES: Transit use (number of subway and bus rides each week), physical activity (minutes of walking or bicycling each day), and weight, measured once in early 2016. RESULTS: Of 937 people analysed in total, 180 had won a permit to purchase a new vehicle. Winning the permit lottery resulted in the purchase of an additional vehicle 91% of the time (95% confidence interval 89% to 94%; P<0.001). About five years after winning, winners took significantly fewer weekly transit rides (-2.9 rides (-5.1 to -0.7); P=0.01) and walked and cycled significantly less (-24.2 minutes (-40.3 to -8.1); P=0.003) than those who did not win the lottery. Average weight did not change significantly between lottery winners and losers. Among those aged 50 and older, however, winners' weight had increased relative to that of losers (10.3 kg (0.5 to 20.2); P=0.04) 5.1 years after winning. CONCLUSIONS: These data indicate that vehicle ownership in a rapidly growing global city led to long term reductions in physical activity and increase in weight. Continuing increases in car use and ownership in developing and middle income countries could adversely affect physical health and obesity rates.

RESUMO

Introduction: Physical inactivity is an important risk factor for many aging-related symptoms. Studies suggest that physical activity may help to relieve tinnitus and headache. Objective: To investigate the presence of tinnitus and headache in elderly individuals by associating it with the lack of regular physical activity. Methods: A cross-sectional study including elderly individuals who live independently. The practice of physical activity and the complaints of headache and of tinnitus were checked by means of a questionnaire with objective questions. The statistical analysis was performed using the chi-squared test and relative risk, and a multiple logistic regression model was used to determine how well each factor predicted headache while controlling for each of the other factors. Results: Based on a sample of 494 subjects, it was found that 213 (43.11%) complained of tinnitus. Among the complainants, 97 (45.53%) practiced physical activity regularly. We have confirmed associations between headache with lack of physical activity among elderly individuals with tinnitus (p = 0.0440). It was also observed that certain factors, such as male gender and tinnitus, are independent factors for the complaint of headache. Conclusion: We have found that headache could be a symptom related to the lack of regular physical activity among elderly individuals with tinnitus. (AU)

RESUMO

Young individuals with chronic exercise-induced lower leg pain (ELP) who have normal compartmental muscle pressures and normal imaging occasionally suffer from a nerve entrapment syndrome. These patients have consistently undergone a variety of diagnostic tests and often futile therapies prior to arriving at the correct diagnosis. Awareness among traumatologists regarding these nerve entities is low. A lower leg discomfort that is frequently present at night but worsens during exercise combined with altered foot skin sensations suggests an entrapment of the common peroneal or tibial nerve. If conservative therapies fail, neurolysis is advised.

RESUMO

The aim of the research is to study the dynamics of functional capabilities of 17-22 year old girls with different vegetative status during the ovarian-menstrual cycle. By the use of questionnaires and anthropo-physiometry, 28 girls with low motor activity and a regular (more than 3 cycles) menstrual cycle were selected, which allowed to determine the phases by calendar method. All of the surveyed people were in the main medical group of health. The modernized method of D. N. Davidenko muscular load was used. The heart rate was recorded at rest when the heart rate was reached at 150-155 beats per minute, at the end of testing and on the 5th minute of recovery, sitting on the cycle ergometer. To estimate the variability of the heart rate, a number of indicators proposed by R. M. Bayevsky were calculated to characterize the state of the vegetative nervous system. The degree of centralization of heart rate control was determined by means of a stress index, on the basis of which the group of patients was divided into subgroups depending on the type of regulation in the state of relative rest in the first (menstrual) phase of the menstrual cycle. It has been identified that vagotonics are characterized by higher, and sympathicotonics - by low values of PWC170, as an integral indicator of the body's functional capabilities. The optimal phases of physical performance for girls with vagotonic type of regulation are menstrual and premenstrual, with normotonic - menstrual and ovulatory, with sympathicotonic - postmenstrual and postovulatory phases of OMC. Physical activity in other phases of the cycle increases the level of functional stress and can provoke pre-pathological and pathological conditions.

RESUMO

To explore associated risk factors and their interactions with type 2 diabetes (T2DM) among the elderly with prediabetes in rural areas in China.A nested case-control study was conducted in a fixed cohort to identify the risk factors for T2DM among the elderly with prediabetes in rural areas of Yiyang City in China. A total of 37 elderly with T2DM were included in the cases group and 111 elderly subjects with prediabetes were matched in the control group. Data related to sociodemographic characteristics, lifestyle behavior, and anthropometric variables were collected by trained staff using standard tools. The risk factors for T2DM were determined using conditional logistic regression analysis, and their additive interactions were also explored.Multivariable conditional logistic regression analysis results showed that overweight/obesity (odds ratio [OR] = 4.80, 95% confidence interval [CI]: 1.20-12.28), family history of diabetes (OR = 3.63, 95% CI: 1.03-12.81), physically inactive (OR = 3.08, 95% CI: 1.14-8.30), high waist-to-hip ratio (WHR) (OR = 3.15, 95% CI: 1.27-7.80), and inadequate diabetes-specific health literacy (DSHL) (OR = 3.92, 95% CI: 1.14-13.48) increased the risk for T2DM. Additive interactions for T2DM were observed between a family history of diabetes and high WHR with a relative excess risk of interaction (RERI) of 10.02 (95% CI: 4.25, 15.78), and between high WHR and overweight or obesity, with an RERI of 3.90 (95% CI: 0.36, 7.44).The independent risk factors for T2DM are overweight or obesity, high WHR, family history of diabetes, physically inactive, and inadequate DSHL. High WHR as a risk factor for T2DM has additive interactions with family history of diabetes and overweight or obesity.

RESUMO

A small proportion of patients with exertional leg pain (ELP) have deep posterior chronic exertional compartment syndrome (dp-CECS). These individuals report pain, tightness and cramps deep in the calf muscles that are elicited by exercise, but may also be present during rest to a lesser extent. Physical examination often reveals painful palpation of the flexor muscles in the area immediately dorsomedial to the tibial bone. Diagnosis is confirmed by intracompartmental pressure testing. Various entities may mimic or coincide with dp-CECS, including medial tibial stress syndrome (MTSS) and popliteal artery entrapment syndrome (PAES). Fasciotomy of multiple flexor muscles is the only treatment that achieves a beneficial outcome. The aim of this overview is to discuss the diagnosis and management of dp-CECS.

RESUMO

BACKGROUND: Pulmonary hypertension (PH) is defined as an elevation of mean pulmonary-arterial pressure by > 20 mmHg at rest, which may lead to right heart failure. Physical exercise has not been regularly recommended for PH patients for fear of symptom deterioration or occurrence of exercise-induced adverse events. METHODS: Three electronic databases were searched for randomized, controlled trials investigating exercise training in PH patients using the following keywords: "pulmonary hypertension" OR "pulmonary arterial hypertension" AND "exercise" OR "pulmonary rehabilitation" AND "randomized". RESULTS: Five studies involving 187 PH patients were included in this systematic review. Exercise programs lasted for 3 - 12 weeks (e. g. endurance training for 10 - 45 minutes; 60 - 80 % of the peak heart rate). PH patients significantly improved exercise capacity compared to controls in 6-minute walk distance (+ 45 m; 95 % CI: 26 m - 64 m) or peak oxygen consumption (+ 2.3 ml/kg/min; 95 % CI: 1.8 - 2.9 ml/kg/min), both p < 0.001. Also, physical and mental quality of life improved significantly by exercise training. No exercise-induced adverse events were observed. CONCLUSION: Supervised exercise training can safely and significantly improve physical performance and quality of life in clinically stable PH patients with optimal drug treatment. However, larger studies including a wider range of PH are mandatory.

RESUMO

BACKGROUND: Neck pain is an important cause of disability. In spite of its high prevalence rate, treatment of the disorder is a challenging topic. Exercise therapy appears to be effective at decreasing pain and improving function for patients with NP in practice guidelines. Core stability exercise is becoming increasingly popular for NP. However, it is currently unknown whether core stability exercise produces more beneficial effects than general exercise in patients with NP. The aim of this study is to explore the therapeutic effect of core stability exercise for neck pain. METHODS: This review will only include randomized controlled trials (RCTs). Published articles from July 2009 to July 2019 will be identified using electronic searches. Search strategy will be performed in 3 English databases, 1 Chinese database, and the WHO International Clinical Trials Registry Platform. Two reviewers will screen, select studies, extract data, and assess quality independently. The methodological quality including the risk of bias of the included studies will be evaluated using a modified assessment form, which is based on Cochrane assessment tool and Physiotherapy Evidence Database scale. Review Manager Software (Revman5.3) will be used for heterogeneity assessment, generating funnel-plots, data synthesis, subgroup analysis, and sensitivity analysis. We will use GRADE system to evaluate the quality of our evidence. RESULTS: We will provide some more practical and targeted results investigating the effect of Core Stability Exercise (CSE) for Neck Pain (NP) in the current meta-analysis. Meanwhile, we will ascertain study progress of Core Stability Exercise for Neck Pain and find out defects or inadequacies of previous studies, so that future researchers could get beneficial guidance for more rigorous study. CONCLUSION: The stronger evidence about Neck Pain's rehabilitative effect and safety will be provided for clinicians and policymakers. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42017055711. ETHICS AND DISSEMINATION: We do not apply for formal ethical approval from ethics committee because all of the study data in our review will be obtained in an anonymous way. Findings of this study are projected to be disseminated through peer-review publications.

RESUMO

Pulmonary Rehabilitation Abstract. Pulmonary rehabilitation is a comprehensive therapeutic approach for patients with advanced chronic lung diseases which leads to a decline of dyspnea, an increase of exercise capacity and an increase of quality of life. Further effects are a reduction of frequency of hospitalisations and an increase of physical activity, if a self management education program is integrated. Pulmonary rehabilitation incorporates an individualised training program with focus on endurance, strength and mobility, further a disease specific education with the goal to improve self efficacy and self management of the patients, specially with the goal to improve their daily physical activity. Due to the good evidence of pulmonary rehabilitation, the accredited programs are accepted and paid by the swiss insurances.
