Effectiveness of a Home-Based Telehealth Exercise Training Program for Patients With Cardiometabolic Multimorbidity: A Randomized Controlled Trial.

BACKGROUND: Exercise training has positive effects on the management of cardiometabolic conditions. Little is known about the effectiveness of home-based telehealth exercise training programs among patients with cardiometabolic multimorbidity, which is associated with functional decline and decreased health-related quality of life. OBJECTIVE: The aim of this study was to determine the effectiveness of a 12-week home-based telehealth exercise training program designed to increase physical activity and exercise capacity and improve health-related quality of life in patients with cardiometabolic multimorbidity. METHODS: A randomized controlled trial was conducted. Fifty eligible patients with 2 or more cardiometabolic conditions from outpatient clinics of a medical center in Northern Taiwan were randomized to either an experimental group (EG; received a 12-week home-based telehealth exercise training program) or a control group (CG; maintained usual lifestyles). The home-based telehealth exercise training program consisted of 36 individualized home-based exercise training sessions and a weekly reminder for maintenance of exercise and providing patient support. Amounts of physical activity, exercise capacity, and health-related quality of life were assessed at baseline and 12 weeks. Generalized estimating equations were used to examine the intervention effects via the interaction of time and group. RESULTS: The EG had higher amounts of physical activity (ß = 1333, P = .004) and moderate-intensity physical activity (ß = 330, P = .04) than the CG after the intervention. The EG had increased exercise capacity (VO2peak, ß = 4.43, P = .04), as well as improved health-related quality of life (physical function, ß = 7.55, P = .03; and physical component summary, ß = 4.42, P = .03) compared with those in the CG. CONCLUSIONS: A 12-week home-based telehealth exercise training program is feasible and effective in increasing amounts of physical activity, elevating exercise capacity, and improving health-related quality of life in patients with cardiometabolic multimorbidity.

Circadian rhythms and exercise - re-setting the clock in metabolic disease.

Perturbed diurnal rhythms are becoming increasingly evident as deleterious events in the pathology of metabolic diseases. Exercise is well characterized as a crucial intervention in the prevention and treatment of individuals with metabolic diseases. Little is known, however, regarding optimizing the timing of exercise bouts in order to maximize their health benefits. Furthermore, exercise is a potent modulator of skeletal muscle metabolism, and it is clear that skeletal muscle has a strong circadian profile. In humans, mitochondrial function peaks in the late afternoon, and the circadian clock might be inherently impaired in myotubes from patients with metabolic disease. Timing exercise bouts to coordinate with an individual's circadian rhythms might be an efficacious strategy to optimize the health benefits of exercise. The role of exercise as a Zeitgeber can also be used as a tool in combating metabolic disease. Shift work is known to induce acute insulin resistance, and appropriately timed exercise might improve health markers in shift workers who are at risk of metabolic disease. In this Review, we discuss the literature regarding diurnal skeletal muscle metabolism and the interaction with exercise bouts at different times of the day to combat metabolic disease.

Revealing the Neural Mechanisms Underlying the Beneficial Effects of Tai Chi: A Neuroimaging Perspective.

Tai Chi Chuan (TCC), a traditional Chinese martial art, is well-documented to result in beneficial consequences in physical and mental health. TCC is regarded as a mind-body exercise that is comprised of physical exercise and meditation. Favorable effects of TCC on body balance, gait, bone mineral density, metabolic parameters, anxiety, depression, cognitive function, and sleep have been previously reported. However, the underlying mechanisms explaining the effects of TCC remain largely unclear. Recently, advances in neuroimaging technology have offered new investigative opportunities to reveal the effects of TCC on anatomical morphologies and neurological activities in different regions of the brain. These neuroimaging findings have provided new clues for revealing the mechanisms behind the observed effects of TCC. In this review paper, we discussed the possible effects of TCC-induced modulation of brain morphology, functional homogeneity and connectivity, regional activity and macro-scale network activity on health. Moreover, we identified possible links between the alterations in brain and beneficial effects of TCC, such as improved motor functions, pain perception, metabolic profile, cognitive functions, mental health and sleep quality. This paper aimed to stimulate further mechanistic neuroimaging studies in TCC and its effects on brain morphology, functional homogeneity and connectivity, regional activity and macro-scale network activity, which ultimately lead to a better understanding of the mechanisms responsible for the beneficial effects of TCC on human health.

The effect of dietary intervention on the metabolic and behavioural impairments generated by short term high fat feeding in the rat.

Previous studies have shown that rats fed a high calorie diet rich in saturated fat for 12weeks exhibit peripheral insulin resistance and impairments of behavioural flexibility when switched from an operant delayed matching to place (DMTP) schedule to a delayed non-matching to place (DNMTP) schedule. However, the metabolic changes evoked by feeding a high fat (HF) diet can be observed within two weeks of commencing the diet. The current study has confirmed that 4weeks exposure to an HF diet resulted in increased body weight, peripheral insulin resistance and plasma leptin. Studies performed during weeks 3 and 4 on the HF diet revealed suppressed lever pressing rates and impaired behavioural flexibility in the operant DMTP/DNMTP task. When animals fed the HF diet were then returned to a standard chow (SC) diet for 5weeks their weight and blood biochemistry no longer differed from those measured in animals that had never been exposed to the HF diet. The animals restored to the SC diet exhibited a clear ability to acquire the DNMTP schedule of reinforcement although these animals continued to lever press at a lower rate when compared with animals that received the SC diet throughout. The data suggest that exposure to an HF diet diminishes the motivation to respond for a reward and, thus, the capacity to adapt behavioural performance. This deficit was ameliorated, but not totally reversed, by the dietary intervention. If also true for humans, the results suggest that deficits in behavioural flexibility develop after only a short period on a high calorie diet but may be largely reversible through simple dietary intervention, at least in the early stages of deficit development. However, the putative effects of short-term exposure to an HF diet on behavioural motivation may persist for some time after switching to a healthier low fat diet and remain a problem for those seeking to adopt a healthier diet.

Influence Diagram As a Support Tool for Clinical Decisions In Cardiopulmonary And Metabolic Rehabilitation.

An influence diagram (ID) is a method of graphical representation of uncertain knowledge, which can be employed to support decisions in health care using probabilistic reasoning. We aimed to describe the development of an ID to support the decision-making process in phase II at Cardiopulmonary and Metabolic Rehabilitation Program (CPMR). The development of the ID was carried out through the identification of relevant variables and their possible values, as well as the identification of details of each variable, in order to find a network structure that appropriately connects the nodes that represent the variables, with arcs linking acyclic graphs, and to build the graph using specialized knowledge and the conditional probability table for each node in the graph. In spite of the complexity of the interactions, the model obtained with the ID seems to contribute in the decision-making process in phase II CPMR, providing a second opinion to the health pratictioner and helping in diagnostic, therapeutic and decision-making processes, since it is useful in situations with non-linear modeling or with absent or uncertain information.

Exercise prevents downregulation of hippocampal presynaptic proteins following olanzapine-elicited metabolic dysregulation in rats: Distinct roles of inhibitory and excitatory terminals.

Schizophrenia patients treated with olanzapine, or other second-generation antipsychotics, frequently develop metabolic side-effects, such as glucose intolerance and increased adiposity. We previously observed that modeling these adverse effects in rodents also resulted in hippocampal shrinkage. Here, we investigated the impact of olanzapine treatment, and the beneficial influence of routine exercise, on the neurosecretion machinery of the hippocampus. Immunodensities and interactions of three soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins (syntaxin-1, synaptosome-associated protein of 25kDa (SNAP-25) and vesicle-associated membrane protein (VAMP)), synaptotagmin and complexins-1/2 were quantified in the hippocampus of sedentary and exercising rats exposed over 9weeks to vehicle (n=28) or olanzapine (10mg/kg/day, n=28). In addition, brain sections from subgroups of sedentary animals (n=8) were co-immunolabeled with antibodies against vesicular GABA (VGAT) and glutamate (VGLUT1) transporters, along with syntaxin-1, and examined by confocal microscopy to detect selective olanzapine effects within inhibitory or excitatory terminals. Following olanzapine treatment, sedentary, but not exercising rats showed downregulated (33-50%) hippocampal densities of SNARE proteins and synaptotagmin, without altering complexin levels. Strikingly, these effects had no consequences on the amount of SNARE protein-protein interactions. Lower immunodensity of presynaptic proteins was associated with reduced CA1 volume and glucose intolerance. Syntaxin-1 depletion appeared more prominent in VGAT-positive terminals within the dentate gyrus, and in non-VGAT/VGLUT1-overlapping areas of CA3. The present findings suggest that chronic exposure to olanzapine may alter hippocampal connectivity, especially in inhibitory terminals within the dentate gyrus, and along the mossy fibers of CA3. Together with previous studies, we propose that exercise-based therapies might be beneficial for patients being treated with olanzapine.

Mild training program in metabolic syndrome improves the efficiency of the oxygen pathway.

In sedentary patients suffering of metabolic syndrome, we evaluated the effects of mild exercise program (EP) on the efficiency of the oxygen delivery system. The prescription of exercise (40 min/session, 3 times/week) was tailored at workload corresponding to ∼90% individual anaerobic threshold (AT). EP improved significantly by ∼10% peak values of oxygen consumption (VO2) and heart rate (HR). Furthermore, in response to steady state workload at 90% AT, EP shortened the time constant of VO2, HR and the ratio VO2/HR (reflecting arterio-venous O2 concentration difference) by ∼6s. EP also decreased the elastic respiratory work due to a change in breathing pattern implying a larger contribution of respiratory rate, at the expense of tidal volume during exercise hyperventilation. In all subjects the perceived fatigue (Borg) decreased after training. This study supports a positive effect of a mild EP for the adaptive response of the oxygen chain to face metabolic needs compatible with daily life in patients affected by metabolic syndrome.

Supervised exercise improves cutaneous reinnervation capacity in metabolic syndrome patients.

OBJECTIVE: Unmyelinated cutaneous axons are vulnerable to physical and metabolic injury, but also capable of rapid regeneration. This balance may help determine risk for peripheral neuropathy associated with diabetes or metabolic syndrome. Capsaicin application for 48 hours induces cutaneous fibers to die back into the dermis. Regrowth can be monitored by serial skin biopsies to determine intraepidermal nerve fiber density (IENFD). We used this capsaicin axotomy technique to examine the effects of exercise on cutaneous regenerative capacity in the setting of metabolic syndrome. METHODS: Baseline ankle IENFD and 30-day cutaneous regeneration after thigh capsaicin axotomy were compared for participants with type 2 diabetes (n = 35) or metabolic syndrome (n = 32) without symptoms or examination evidence of neuropathy. Thirty-six participants (17 with metabolic syndrome) then joined twice weekly observed exercise and lifestyle counseling. Axotomy regeneration was repeated in month 4 during this intervention. RESULTS: Baseline distal leg IENFD was significantly reduced for both metabolic syndrome and diabetic groups. With exercise, participants significantly improved exercise capacity and lower extremity power. Following exercise, 30-day reinnervation rate improved (0.051 ± 0.027 fibers/mm/day before vs 0.072 ± 0.030 after exercise, p = 0.002). Those who achieved improvement in more metabolic syndrome features experienced a greater degree of 30-day reinnervation (p < 0.012). INTERPRETATION: Metabolic syndrome was associated with reduced baseline IENFD and cutaneous regeneration capacity comparable to that seen in diabetes. Exercise-induced improvement in metabolic syndrome features increased cutaneous regenerative capacity. The results underscore the potential benefit to peripheral nerve function of a behavioral modification approach to metabolic improvement.

High-intensity interval training in patients with lifestyle-induced cardiometabolic disease: a systematic review and meta-analysis.

BACKGROUND/AIM: Cardiorespiratory fitness (CRF) is a strong determinant of morbidity and mortality. In athletes and the general population, it is established that high-intensity interval training (HIIT) is superior to moderate-intensity continuous training (MICT) in improving CRF. This is a systematic review and meta-analysis to quantify the efficacy and safety of HIIT compared to MICT in individuals with chronic cardiometabolic lifestyle diseases. METHODS: The included studies were required to have a population sample of chronic disease, where poor lifestyle is considered as a main contributor to the disease. The procedural quality of the studies was assessed by use of a modified Physiotherapy Evidence Base Database (PEDro) scale. A meta-analysis compared the mean difference (MD) of preintervention versus postintervention CRF (VO2peak) between HIIT and MICT. RESULTS: 10 studies with 273 patients were included in the meta-analysis. Participants had coronary artery disease, heart failure, hypertension, metabolic syndrome and obesity. There was a significantly higher increase in the VO2peak after HIIT compared to MICT (MD 3.03 mL/kg/min, 95% CI 2.00 to 4.07), equivalent to 9.1%. CONCLUSIONS: HIIT significantly increases CRF by almost double that of MICT in patients with lifestyle-induced chronic diseases.

Effects of aerobic interval training on metabolic complications and cardiorespiratory fitness in young adults with psychotic disorders: a pilot study.

AIM: To assess the feasibility of implementing a 14-week aerobic interval training (AIT) program within a first-episode psychosis (FEP) service and its efficacy in improving metabolic outcomes and cardiorespiratory fitness. METHOD: Twenty-five male subjects participated in 30-minute sessions of AIT twice a week. RESULTS: Sixteen of 25 subjects completed the training program. There was a significant decrease in waist circumference (WC; -4.3 cm; p=0.015), resting heart rate (-8.6 bpm; p<0.05) and a 38% increase in VO2max (p<0.001). The decrease in WC (-5.6 cm; p<0.01) was more pronounced for subjects who completed at least 64% of the planned sessions. CONCLUSION: An AIT program could be implemented in FEP patients and improve WC and cardiorespiratory fitness over a relatively short period.

[Rehabilitation for digestive and metabolic diseases. Quo vadis?]. / Rehabilitation bei Verdauungs- und Stoffwechselkrankheiten. Quo vadis?

The position of rehabilitation in gastroenterology, hepatology and metabolic diseases has changed little in the last 25 years. Initial improvements in quality are oriented more to the content of rehabilitative measures and less to organizational basic conditions. Nevertheless, there is an urgent need for action if rehabilitation medicine is to achieve an equivalent and recognized position in the interaction between primary care and other medical specialties. In this article suggestions for expedient prerequisites and utilization options of rehabilitation in the fields of hepatogastroenterology and metabolism will be presented, which are also oriented to the exemplary implemented concepts from Sweden and The Netherlands.

Avaliação do sistema locomotor de pacientes de programas de reabilitação cardiopulmonar e metabólica / Evaluation of the musculoskeletal system of patients in cardiopulmonary and metabolic rehabilitation programs

FUNDAMENTO: Participantes dos programas de reabilitação cardiopulmonar e metabólica (RCPM) podem apresentar alterações locomotoras que prejudiquem a aderência e a efetividade do tratamento. OBJETIVO: Desenvolver instrumento para avaliar o sistema locomotor e identificar problemas, principalmente aqueles relacionados com o exercício, possibilitando a triagem dos pacientes, ou seja, liberação sem restrições, liberação com restrições e não liberação antes de aval especializado. MÉTODOS: Construção e validação (segundo o alfa de Cronbach) de inventário de avaliação do sistema locomotor (IASL), para subsequente aplicação em participantes da RCPM. RESULTADOS: Por meio do IASL, cuja avaliação interna apresentou parâmetros de validade e confiabilidade satisfatórios, foram avaliados 103 indivíduos participantes de programas de RCPM, sendo 33 homens (32 por cento) e 70 mulheres (68 por cento), com idades entre 36 e 84 anos, dos quais 47 (45,6 por cento) já haviam recebido diagnóstico de problema do sistema locomotor, 39 (37,9 por cento) já haviam recebido tratamento específico para o sistema locomotor, 33 (32 por cento) costumavam usar fármacos para alívio de sintomas do sistema locomotor, e 10 (9,7 por cento) haviam recebido proibição médica para algum tipo de exercício. Ressalte-se que 48 indivíduos (46,6 por cento) relataram sentir dor no sistema locomotor que, em 14 (13,6 por cento) deles, piorava com o exercício, o que deveria impedir a participação em programa de exercícios antes de aval de especialista. CONCLUSÃO: O IASL, que apresentou parâmetros de validade e confiabilidade satisfatórios, evidenciou que, para praticamente metade dos participantes de programas de RCPM, existia alguma restrição para a prática de exercícios e que alguns não deveriam ter sido liberados sem o aval de especialista.

BACKGROUND: Participants of cardiopulmonary and metabolic rehabilitation (CPMR) programs may present with musculoskeletal changes that may affect treatment compliance and effectiveness. OBJECTIVE: To develop an instrument for evaluation of the musculoskeletal system and identification of problems, especially those related to exercise, so that patients can be cleared to exercise with no restrictions, cleared with restrictions, or not cleared before approval from a specialist. METHODS: Construction and validation (according to Cronbach’s alpha) of a musculoskeletal system assessment inventory (MSSAI), for subsequent administration to participants in CPMR programs. RESULTS: A total of 103 individuals participating in CPMR programs were evaluated by means of the MSSAI, whose internal validity and reliability proved to be satisfactory. Of these, 33 were men (32 percent) and 70 were women (68 percent), with age ranging from 36 to 84 years; 47 (45.6 percent) had already been diagnosed with musculoskeletal system disorders; 39 (37.9 percent) had already received specific treatment for the musculoskeletal system; 33 (32 percent) used to take medications to relieve symptoms related to the musculoskeletal system; and 10 (9.7 percent) had a medical restriction for performing some type of exercise. We should point out that 48 individuals (46.6 percent) reported pain in the musculoskeletal system; in 14 (13.6 percent) of them, the pain worsened by exercise, and this should have prevented them from participating in exercise programs before receiving approval from a specialist. CONCLUSION: The MSSAI, whose internal validity and reliability proved satisfactory, showed that there was some restriction to exercise practice for almost half of the individuals participating in CPMR programs, and that some of them should not have been cleared without approval from a specialist.

[Bicarbonate calcium mineral water with carbon dioxide in rehabilitation of children with dismetabolic nephropathies complicated by renal inflammation]. / Uglekislaia gidrokarbonatnaia kal'tsievaia mineral'naia voda v reabilitatsii detei s dismetabolicheskimi nefropatiiami v sochetanii s vospalitel'nymi zabolevaniiami pochek.

A renal function was studied in children with dismetabolic nephropathy and renal inflammation before and after spa treatment with low-mineral water from the spring "Gornovodnoye". Drinking the water resulted in intensification of 24-h diuresis in increasing proportion of sodium and chlorine ions concentrations and decreasing proportion of calcium and magnesium ions concentrations. A membrane-stabilizing action of Gornovodnenskaya mineral water reduced oxaluria and uraturia. An effective scheme of balneotherapy is proposed.

[Ambulant rehabilitation of patients with gastrointestinal and metabolic diseases]. / Ambulante/teilstationäre Rehabilitation von Patienten mit Krankheiten der Verdauungsorgane und des Stoffwechsels.

For the following reasons it has, despite plausible different opinions, seldom been possible realize ambulant rehabilitation offers:For historical reasons gut rehabilitation centers lie outside of conurbations. A model of gastrointestinal-oncologic rehabilitation supports developing an entirely new concept for ambulant treatments, instead of merely copying the presently in-patient rehabilitation therapy. In the exemplary thoughts of the GRVS, which were already presented five years ago, quantitative factors have not been taken into consideration satisfactorily. Considering this the following three diagnosis groups become relevant - diabetes m. - obesity - gastrointestinal cancer. The needed ambulant rehabilitation concepts are to be connected to the long-term ambulant treatment, available close to the patient's home city.
