App-based telerehabilitation program for older adults on waiting list for physiotherapy after hospital discharge: a feasibility pragmatic randomized trial.

BACKGROUND: Inactivity while waiting for outpatient physiotherapy worsens the physical deconditioning of older adults after hospital discharge. Exercise programs can minimize the progression of deconditioning. In developing countries, telerehabilitation for older adults on the waiting list is still in the early stages. This study aimed to evaluate the feasibility of the study procedures of a telerehabilitation program for older adults waiting for outpatient physiotherapy after hospital discharge. METHODS: This pragmatic randomized controlled trial recruited older adults (≥ 60 years) with several clinical diagnoses on the waiting list for outpatient physiotherapy in the Brazilian public health system after hospital discharge. The telerehabilitation group (n = 17) received a personalized program of multicomponent remote exercises using a smartphone app. The control group (n = 17) followed the usual waiting list. We assessed recruitment and dropout rates, safety, adherence, and satisfaction. The preliminary effects were verified on clinical outcomes. RESULTS: We recruited 5.6 older adults monthly; dropouts were 12%. No serious adverse events were associated with the telerehabilitation program. The weekly adherence was 2.85 (1.43) days, and in 63.3% of the weeks the participants were enrolled, they performed the exercise program at least twice a week. Participants rated the telerehabilitation program as 9.71 (0.21), and the safety of remote exercises without professional supervision as 8.6 (2.2) on a 0-10 scale. CONCLUSIONS: The telerehabilitation program using a smartphone app was safe and presented high participants' satisfaction and adequate adherence, recruitment, and dropout rates. Therefore, the definitive study can be conducted with few modifications. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (ReBEC), RBR-9243v7.

Dysregulated endolysosomal trafficking in cells arrested in the G1 phase of the host cell cycle impairs Salmonella vacuolar replication.

Modulation of the host cell cycle has emerged as a common theme among the pathways regulated by bacterial pathogens, arguably to promote host cell colonization. However, in most cases the exact benefit ensuing from such interference to the infection process remains unclear. Previously, we have shown that Salmonella actively induces G2/M arrest of host cells, and that infection is severely inhibited in cells arrested in G1. In this study, we demonstrate that Salmonella vacuolar replication is inhibited in host cells blocked in G1, whereas the cytosolic replication of the closely related pathogen Shigella is not affected. Mechanistically, we show that cells arrested in G1, but not cells arrested in G2, present dysregulated endolysosomal trafficking, displaying an abnormal accumulation of vesicles positive for late endosomal and lysosomal markers. In addition, the macroautophagic/autophagic flux and degradative lysosomal function are strongly impaired. This endolysosomal trafficking dysregulation results in sustained activation of the SPI-1 type III secretion system and lack of vacuole repair by the autophagy pathway, ultimately compromising the maturation and integrity of the Salmonella-containing vacuole. As such, Salmonella is released in the host cytosol. Collectively, our findings demonstrate that the modulation of the host cell cycle occurring during Salmonella infection is related to a disparity in the permissivity of cells arrested in G1 and G2/M, due to their intrinsic characteristics.Abbreviations: CDK4: cyclin dependent kinase 4; CDK6: cyclin dependent kinase 6; CDK4-CDK6i: CDK4-CDK6 inhibitor IV; cfu: colony-forming units; CHQ: chloroquine; DMSO: dimethyl sulfoxide; EEA1: early endosome antigen 1; FITC: fluorescein isothiocyanate; GFP: green fluorescent protein; hpi: hours post-infection; LAMP1: lysosomal associated membrane protein 1; MAP1LC3B/LC3B: microtubule associated protein 1 light chain 3 beta; MOI: multiplicity of infection; RAB7: RAB7, member RAS oncogene family; SCV: Salmonella-containing vacuole; SPI-1: Salmonella pathogenicity island-1; SPI-2: Salmonella pathogenicity island-2; TFEB: transcription factor EB; T3SS: type III secretion system.

Telerehabilitation program for older adults on a waiting list for physical therapy after hospital discharge: study protocol for a pragmatic randomized trial protocol.

BACKGROUND: Delays in starting physical therapy after hospital discharge worsen deconditioning in older adults. Intervening quickly can minimize the negative effects of deconditioning. Telerehabilitation is a strategy that increases access to rehabilitation, improves clinical outcomes, and reduces costs. This paper presents the protocol for a pragmatic clinical trial that aims to determine the effectiveness and cost-effectiveness of a multi-component intervention offered by telerehabilitation for discharged older adults awaiting physical therapy for any specific medical condition. METHODS: This is a pragmatic randomized controlled clinical trial with two groups: telerehabilitation and control. Participants (n=230) will be recruited among individuals discharged from hospitals who are in the public healthcare system physical therapy waiting lists. The telerehabilitation group will receive a smartphone app with a personalized program (based on individual's functional ability) of resistance, balance, and daily activity training exercises. The intervention will be implemented at the individuals' homes. This group will be monitored weekly by phone and monthly through a face-to-face meeting until they start physical therapy. The control group will adhere to the public healthcare system's usual flow and will be monitored weekly by telephone until they start physical therapy. The primary outcome will be a physical function (Timed Up and Go and 30-s Chair Stand Test). The measurements will take place in baseline, start, and discharge of outpatient physical therapy. The economic evaluations will be performed from the perspective of society and the Brazilian public healthcare system. DISCUSSION: The study will produce evidence on the effectiveness and cost-effectiveness of multi-component telerehabilitation intervention for discharged older adult patients awaiting physical therapy, providing input that can aid the implementation of similar proposals in other patient groups.

Effectiveness of exercises by telerehabilitation on pain, physical function and quality of life in people with physical disabilities: a systematic review of randomised controlled trials with GRADE recommendations.

OBJECTIVE: Investigate whether exercise-based telerehabilitation improves pain, physical function and quality of life in adults with physical disabilities. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES: Searches were performed in AMED, MEDLINE, CINAHL, SPORTDiscus, Embase, PEDro, Cochrane Library and PsycINFO. ELIGIBILITY CRITERIA: Trials were considered if they evaluated exercise by telerehabilitation. The population included adults with physical disability. Comparisons were control and other interventions. The outcomes were pain, physical function and quality of life. Study selection, data extraction and analysis followed the protocol registered in PROSPERO (CRD42019122824). GRADE determined the strength of evidence. RESULTS: Forty-eight trials were included in the quantitative analysis. When compared with other interventions, there was high-quality evidence that telerehabilitation was not different to other interventions for pain (95% CI: -0.4 to 0.1), physical function (95% CI: -0.2 to 0.2) and quality of life (95% CI: -0.1 to 0.5) at long-term. There was moderate-quality evidence that telerehabilitation was not different to other interventions for physical function (95% CI: -0.1 to 0.5) and quality of life (95% CI: -0.2 to 0.5) at short-term. However, due to the low-quality evidence and the small number of trials comparing exercise protocols offered by telerehabilitation with control groups, it is still not possible to state the efficacy of telerehabilitation on pain, function and quality of life at short-term and long-term. CONCLUSIONS: Exercise by telerehabilitation may be an alternative to treat pain, physical function and quality of life in adults with physical disabilities when compared with other intervention.

The Action of Polyphenols in Diabetes Mellitus and Alzheimer's Disease: A Common Agent for Overlapping Pathologies.

Diabetes Mellitus (DM) and Alzheimer's disease (AD) are two prevalent diseases in modern societies, which are caused mainly by current lifestyle, aging and genetic alterations. It has already been demonstrated that these two diseases are associated, since individuals suffering from DM are prone to develop AD. Conversely, it is also known that individuals with AD are more susceptible to DM, namely type 2 diabetes (T2DM). Therefore, these two pathologies, although completely different in terms of symptomatology, end up sharing several mechanisms at the molecular level, with the most obvious being the increase of oxidative stress and inflammation. Polyphenols are natural compounds widely spread in fruits and vegetables whose dietary intake has been considered inversely proportional to the incidence of DM and AD. So, it is believed that this group of phytochemicals may have preventive and therapeutic potential, not only by reducing the risk and delaying the development of these pathologies, but also by improving brain's metabolic profile and cognitive function. The aim of this review is to understand the extent to which DM and AD are related pathologies, the degree of similarity and the relationship between them, to detail the molecular mechanisms by which polyphenols may exert a protective effect, such as antioxidant and anti-inflammatory effects, and highlight possible advantages of their use as common preventive and therapeutic alternatives.

Epidemiological Aspects of Cranioencephalic Trauma at Cuiabá Municipal Hospital, Brazil / Aspectos Epidemiológicos de los Traumatismos Craneoencefálicos Atendidos en el Hospital Municipal de Cuiabá, Brasil

ABSTRACT: Cranioencephalic trauma (CET) is defined is the combination of neural and vascular injuries and their inflammatory effects in the brain, skull and scalp. This modality of trauma may lead to motor, psychological and cognitive sequels or even death. The present study aimed to assess the main epidemiological aspects in victims of CET treated at Cuiabá Municipal Hospital (CMH), Brazil. An observational and analytical study was performed in the medical records of patients diagnosed with CET treated at CMH between July and December of 2000, 2006 and 2011. The information retrieved from the patients consisted of age, sex, place of residence, cause of trauma, association with other trauma, outcomes (death or discharge) and the severity of neurological effect (Glasgow Coma Scale). The data obtained was analyzed descriptively with absolute (n) and relative (%) quantification. Medical records of 669 victims were analyzed, out of which 567 were males (84.7 %). Male patients were aged between 20 and 39 years old (mean age: 32.8 years). The most prevalent cause of trauma was the motorcycle accident (26.6 %). The neurological severity of the CET was mild in most of the cases (32.5 %). Considering the place of residence, most of the patients (n=331; 49.5 %) were from the capital city of Mato Grosso State (Cuiabá, Brazil). Four-hundred seventy-nine (71.6 %) patients progressed without death. A high prevalence rate of CET was observed at CMH. Major attention must be given to young adult victims of motorcycle accidents.

RESUMEN: El traumatismo craneoencefálico (TCE) se define como una combinación de daño neural, insuficiencia vascular y efectos inflamatorios que comprometen el cráneo, el encéfalo y el cuero cabelludo, causando la muerte, o serias secuelas motoras, psicológicas y cognitivas. De esta forma, el objetivo de este trabajo fue evaluar los principales aspectos epidemiológicos en victimas de Traumatismo Craneoencefálico (TCE) atendidas en el Hospital y Sala de Primeros Auxilios Municipal de Cuiabá (HPSMC), Brasil. Se trata de un estudio observacional de historias clínicas del archivo del HPSMC, admitidos con diagnóstico de TCE en el período de julio a diciembre de los años 2000, 2006 y 2011. Se consideraron el rango de edad, el sexo, la procedencia de las víctimas, la causa del trauma, la asociación con otros traumas, la defunción y el alta, el cuadro neurológico (Escala de Coma de Glasgow - ECG). El análisis de los datos fue descriptivo con números absolutos y porcentajes. Se evaluaron historias clínicas de 669 víctimas de TCE, en los que el sexo masculino fue el de mayor prevalencia con 567 casos (84,7 %), con mayor incidencia en el rango de edad de 20 a 39 años (39,2 %), el promedio de edad fue de 32,8 años, siendo la etiología más frecuente los accidentes motociclísticos (26,6 %). En el momento de la admisión de acuerdo al ECG hubo una predominancia de TCE leve (32,5 %). En cuanto a la procedencia, 331 (49,5 %) eran del municipio de Cuiabá. Del total de víctimas, 479 (71,6 %) evolucionaron hasta tener el alta hospitalaria. Se registró una prevalencia elevada de TCE en el HPSMC, con predominancia de víctimas adultas jóvenes de sexo masculino, siendo los accidentes motociclísticos la principal causa.

Characteristics and functional demands of patients at a local rehabilitation network: analysis from first contact. / Características e demandas funcionais de usuários de uma rede local de reabilitação: análise a partir do acolhimento.

The cross sectional study aims to create the patients' profile and understand their demands for seeking public rehabilitation services from Belo Horizonte. Data were analyzed from 516 patients who gained entry into the health care system by means of the Protocol for Identification of Problems for Rehabilitation (PLPR). It allows for gathering information related to one's health and the social context, including a brief functional description (BFD) with 25 items. Most patients were females, mean age of 57 years, and 54% declared to be responsible for the family income. Severe or complete difficulty in at least one item from the BFD was reported by 87%. Pain and Mobility domains showed greater disability. The patient's demand for services referred them mostly to physical therapy (89%), and psychology (14%); 77% were referred to basic care (BC) and 21% to specialized care (SC). Those that started rehabilitation in SC were younger, had increased number of high ratings in item's qualifiers and higher total score in the BFD, indicating increased functional limitation and restriction. It is intended that the information provided by the PLPR may contribute to the organization of patients' flow and the planning of actions.
