RESUMO

Background: Non-medical use of amphetamine and other stimulants prescribed for treatment of attention deficit/hyperactivity disorder (ADHD) is of special concern when combined with alcohol consumption. In a previous study, we modeled chronic ethanol-amphetamine co-use in adolescent Long-Evans (LE) rats and provided evidence that amphetamine attenuates alcohol withdrawal symptoms.Objectives: This project modeled co-use of amphetamine with alcohol in adolescents with ADHD-like symptoms by examining ethanol-amphetamine administration in adolescent Spontaneously Hypertensive Rats (SHR), an experimental model for the study of ADHD. Withdrawal symptoms were compared among SHR and two control rat strains, LE and Wistar Kyoto (WKY).Methods: At postnatal day 32, parallel groups of 12-24 male SHR, WKY and LE rats were administered a liquid diet containing ethanol (3.6%) and/or amphetamine (20 mg/L). Following administration periods up to 26 days, rats were withdrawn from their treatment and tested for overall severity of alcohol withdrawal symptoms, general locomotor activity, and anxiety-like behavior.Results: Overall withdrawal severity was lower for SHR than for LE (p < .001) or WKY (p = .027). Co-consumption of amphetamine decreased withdrawal severity for LE (p = .033) and WKY (p = .011) but not SHR (p = .600). Only WKY showed increased anxiety-like behavior during withdrawal (p = .031), but not after amphetamine co-administration (p = .832).Conclusion: Alcohol withdrawal severity may be attenuated when co-used with amphetamine. However, as a model for ADHD, SHR adolescents appeared resistant to developing significant signs of alcohol withdrawal following alcohol consumption. Whether alcohol withdrawal symptoms are attenuated or absent, potential consequences could include a decreased awareness of an emerging problem with alcohol use.

RESUMO

BACKGROUND: Oncology outreach is a common strategy for increasing rural access to cancer care, where traveling oncologists commute across healthcare settings to extend specialized care. Examining the extent to which physician outreach is associated with timely treatment for rural patients is critical for informing outreach strategies. METHODS: We identified a 100% fee-for-service sample of incident breast cancer patients from 2015 to 2020 Medicare claims and apportioned them into surgery and adjuvant therapy cohorts based on treatment history. We defined an outreach visit as the provision of care by a traveling oncologist at a clinic outside of their primary hospital service area. We used hierarchical logistic regression to examine the associations between patient receipt of preoperative care at an outreach visit (preoperative outreach) and > 60-day surgical delay, and patient receipt of postoperative care at an outreach visit (postoperative outreach) and > 60-day adjuvant delay. RESULTS: We identified 30,337 rural-residing patients who received breast cancer surgery, of whom 4071 (13.4%) experienced surgical delay. Among surgical patients, 14,501 received adjuvant therapy, of whom 2943 (20.3%) experienced adjuvant delay. In adjusted analysis, we found that patient receipt of preoperative outreach was associated with reduced odds of surgical delay (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.61-0.91); however, we found no association between patient receipt of postoperative outreach and adjuvant delay (OR 1.04, 95% CI 0.85-1.25). CONCLUSIONS: Our findings indicate that preoperative outreach is protective against surgical delay. The traveling oncologists who enable such outreach may play an integral role in catalyzing the coordination and timeliness of patient-centered care.

RESUMO

By combining bioimaging and photodynamic therapy (PDT), it is possible to treat cancer through a theranostic approach with targeted action for minimum invasiveness and side effects. Thermally activated delayed fluorescence (TADF) probes have gained recent interest in theranostics due to their ability to generate singlet oxygen (1O2) while providing delayed emission that can be used in time-gated imaging. However, it is still challenging to design systems that simultaneously show (1) high contrast for imaging, (2) low dark toxicity but high phototoxicity and (3) tunable biological uptake. Here, we circumvent shortcomings of TADF systems by designing block copolymers and their corresponding semiconducting polymer dots (Pdots) that encapsulate a TADF dye in the core and expose an additional boron-dipyrromethene (BODIPY) oxygen sensitizer in the corona. This architecture provides orange-red luminescent particles (ΦPL up to 18 %) that can efficiently promote PDT (1O2 QY=42 %) of HeLa cells with very low photosensitizer loading (IC50 ~0.05-0.13 µg/mL after 30 min). Additionally, we design Pdots with tunable cellular uptake but similar PDT efficiencies using either polyethylene glycol or guanidinium-based coronas. Finally, we demonstrate that these Pdots can be used for time-gated imaging to effectively filter out background fluorescence from biological samples and improve image contrast.

RESUMO

PURPOSE: Oncology outreach is a common strategy for extending cancer care to rural patients. However, a nationwide characterization of the traveling workforce that enables this outreach is lacking, and the extent to which outreach reduces travel burden for rural patients is unknown. METHODS: This cross-sectional study analyzed a rural (nonurban) subset of a 100% fee-for-service sample of 355,139 Medicare beneficiaries with incident breast, colorectal, and lung cancers. Surgical, medical, and radiation oncologists were linked to patients using Part B claims, and traveling oncologists were identified by observing hospital service area (HSA) transition patterns. We defined oncology outreach as the provision of cancer care by a traveling oncologist outside of their primary HSA. We used hierarchical gamma regression models to examine the separate associations between patient receipt of oncology outreach and one-way patient travel times to chemotherapy, radiotherapy, and surgery. RESULTS: On average, 9,935 of 39,960 oncologists conducted annual outreach, where 57.8% traveled with low frequency (0-1 outreach visits/mo), 21.1% with medium frequency (1-3 outreach visits/mo), and 21.1% with high frequency (>3 outreach visits/mo). Oncologists provided surgery, radiotherapy, and chemotherapy to 51,715, 27,120, and 5,874 rural beneficiaries, respectively, of whom 2.5%, 6.9%, and 3.6% received oncology outreach. Rural patients who received oncology outreach traveled 16% (95% CI, 11 to 21) and 11% (95% CI, 9 to 13) less minutes to chemotherapy and radiotherapy than those who did not receive oncology outreach, corresponding to expected one-way savings of 15.9 (95% CI, 15.5 to 16.4) and 11.9 (95% CI, 11.7 to 12.2) minutes, respectively. CONCLUSION: Our study introduces a novel claims-based approach for tracking the nationwide traveling oncology workforce and supports oncology outreach as an effective means for improving rural access to cancer care.

RESUMO

BACKGROUND: There are no studies investigating the methodological and report quality of systematic reviews of non-pharmacological interventions for musculoskeletal pain management among children and adolescents. OBJECTIVE: To evaluate the methodological and reporting quality of systematic reviews on conservative non-pharmacological pain management in children and adolescents with musculoskeletal pain. METHODS: Searches were conducted on the Cochrane Database of Systematic Reviews, Medline, Embase, and three other databases. Two pairs of reviewers independently assessed each article according to the predetermined selection criteria. We assessed the methodological quality of systematic reviews, using the AMSTAR 2 checklist and the quality of reporting, using PRISMA checklist. Descriptive analysis was used to summarise the characteristics of all included systematic reviews. The percentage of systematic reviews achieving each item from the AMSTAR 2, PRISMA checklist and the overall confidence in the results were described. RESULTS: We included 17 systematic reviews of conservative non-pharmacological pain management for musculoskeletal pain in children and adolescents. Of the 17 systematic reviews included, nine (53%) were rated as "critically low", seven (41%) were rated as "low", and one (6%) was rated as "high" methodological quality by AMSTAR-2. The reporting quality by items from PRISMA range from 17.6% (95% CI 6.2 to 41) to 100% (95% CI 81.6 to 100). CONCLUSION: This systematic review of physical interventions in children and adolescents showed overall 'very low' to 'high' methodological quality and usually poor reporting quality.

RESUMO

BACKGROUND: Telehealth has emerged as an alternative model for treatment delivery and has become an important component of health service delivery. However, there is inconsistency in the use of terminologies and a lack of research priorities in telehealth in musculoskeletal pain. The purpose of this international, multidisciplinary expert panel assembled in a modified three-round e-Delphi survey is to achieve a consensus on research priorities and for the standard terminology for musculoskeletal pain telehealth practice. METHODS: In this international modified e-Delphi survey, we invited an expert panel consisting of researchers, clinicians, consumer representatives, industry partners, healthcare managers, and policymakers to participate in a three-round e-Delphi. Expert panels were identified through the Expertscape website, PubMed database, social media, and a snowball approach. In Round 1, potential research priorities and terminologies were presented to panel members. Panel members rated the agreement of each research priority on a 5-point Likert scale and an 11-point numerical scale, and each terminology on a 5-point Likert scale for the "telehealth in musculoskeletal pain " field over rounds. At least 80% of the panel members were required to agree to be deemed a consensus. We analyzed the data descriptively and assessed the stability of the results using the Wilcoxon matched-pairs signed rank test. RESULTS: We performed an international e-Delphi survey from February to August 2022. Of 694 invited people, 160 panel members participated in the first round, 133 in the second round (83% retention), and 134 in the third round (84% retention). Most of the panel members were researchers 76 (47%), clinicians 57 (36%), and consumer representatives 9 (6%) of both genders especially from Brazil 31 (19%), India 22 (14%), and Australia 19 (12%) in the first round. The panel identified fourteen telehealth research priorities spanned topics including the development of strategies using information and communication technology, telehealth implementation services, the effectiveness and cost-effectiveness of telehealth interventions, equity of telehealth interventions, qualitative research and eHealth literacy in musculoskeletal pain conditions from an initial list of 20 research priorities. The consensus was reached for "digital health" and "telehealth" as standard terminologies from an initial list of 37 terminologies. CONCLUSION: An international, multidisciplinary expert consensus recommends that future research should consider the 14 research priorities for telehealth musculoskeletal pain reached. Additionally, the terms digital health and telehealth as the most appropriate terminologies to be used in musculoskeletal telehealth research.

RESUMO

This study aims to elucidate the internal load, performance, physiological, and perceptual recovery responses during four weeks of traditional judo training. Ten cadet and junior judo athletes were evaluated daily for four weeks, in which their perception of recovery, heart rate variability, handgrip strength, and countermovement jump performance were assessed. A one-way repeated-measures ANOVA was performed to analyze the variables across the weeks. A significant time effect in internal load (F = 6.51; p = 0.001) has been observed. Handgrip test performance showed significantly higher values in the 3rd and 4th weeks (p <0.001), while countermovement jump performance was significantly higher in the 4th week (p =0.0007). The heart rate variability's coefficient of variation was lower in both the 3rd and 4th weeks (p =0.02). Regarding perceptual aspects, the Hooper Index showed a significant time effect (p =0.04), but pairwise comparison did not reveal differences between weeks. The present study indicates that neuromuscular, physiological, and perceptual responses to training load alterations present different time courses. This must be considered for the adequate monitoring of training programs.

RESUMO

BACKGROUND: Subclinical depression (SD) is a mental health disorder characterized by minor depressive symptoms. Most SD patients are treated in the primary practice, but many respond poorly to treatment at the expense of provider resources. Stepped care approaches are appealing for tiering SD care to efficiently allocate scarce resources while jointly optimizing patient outcomes. However, stepped care can be time inefficient, as some persons may respond poorly and be forced to suffer with their symptoms for prolonged periods. Machine learning can offer insight into optimal treatment paths and inform clinical recommendations for incident patients. METHODS: As part of the Step-Dep trial, participants with SD were randomized to receive stepped care (N=96) or usual care (N=140). Machine learning was used to predict changes in depressive symptoms every three months over a year for each treatment group. RESULTS: Tree-based models were effective in predicting PHQ-9 changes among patients who received stepped care (r=0.35-0.46, MAE=0.14-0.17) and usual care (r=0.34-0.49, MAE=0.15-0.18). Patients who received stepped care were more likely to reduce PHQ-9 scores if they had high PHQ-9 but low HADS-A scores at baseline, a low number of chronic illnesses, and an internal locus of control. LIMITATIONS: Models may suffer from potential overfitting due to sample size limitations. CONCLUSION: Our findings demonstrate the promise of machine learning for predicting changes in depressive symptoms for SD patients receiving different treatments. Trained models can intake incident patient information and predict outcomes to inform personalized care.

RESUMO

INTRODUCTION: Recent clinical practice guidelines recognize the importance of the biopsychosocial model in the management of patients with chronic nonspecific low back pain, and the attitudes and beliefs of physical therapists are believed to directly influence clinical decision-making. OBJECTIVE: To investigate factors associated to biomedical and biopsychosocial approaches and its impact on attitudes and beliefs to treat patients with chronic nonspecific low back pain. METHOD: This was a cross-sectional study conducted online with 302 Brazilian physiotherapists who treat patients with nonspecific chronic low back pain. The HC-PAIRS and PABS-PT were used to investigate attitudes and beliefs low back pain. Descriptive statistics and bivariate analyses were performed for association tests, comparing the scores on the scales between groups. In addition, multiple linear regression analyses were also used. RESULTS: The overall mean score of HC-PAIRS was 54.0 (9.0), and the biomedical and biopsychosocial factors of PABS-PT were 29.7 (9.0) and 36.2 (5.3), respectively. Significant associations were identified between gender (p = 0.04) and level of academic training (p < 0.00) and both scales, HC-PAIRS and PABSPT, respectively. CONCLUSION: Sociodemographic characteristics were associated with the beliefs of physical therapists; a higher score for treatment options for chronic low back pain based on the biomedical mode, was observed in female physiotherapist and in physios with higher education level. Variables such as age and length of professional experience indicated that the lower the age and/or length of professional experience of Brazilian physical therapists, the stronger the belief in the relationship between low back pain and tissue damage.

RESUMO

Skeletal muscle plays a key role in systemic energy homeostasis besides its contractile function, but what links these functions is poorly defined. Protein Arginine Methyl Transferase 5 (PRMT5) is a well-known oncoprotein but also expressed in healthy tissues with unclear physiological functions. As adult muscles express high levels of Prmt5, we generated skeletal muscle-specific Prmt5 knockout (Prmt5MKO ) mice. We observe reduced muscle mass, oxidative capacity, force production, and exercise performance in Prmt5MKO mice. The motor deficiency is associated with scarce lipid droplets in myofibers due to defects in lipid biosynthesis and accelerated degradation. Specifically, PRMT5 deletion reduces dimethylation and stability of Sterol Regulatory Element-Binding Transcription Factor 1a (SREBP1a), a master regulator of de novo lipogenesis. Moreover, Prmt5MKO impairs the repressive H4R3 symmetric dimethylation at the Pnpla2 promoter, elevating the level of its encoded protein ATGL, the rate-limiting enzyme catalyzing lipolysis. Accordingly, skeletal muscle-specific double knockout of Pnpla2 and Prmt5 normalizes muscle mass and function. Together, our findings delineate a physiological function of PRMT5 in linking lipid metabolism to contractile function of myofibers.

RESUMO

BACKGROUND: The biogenic synthesis of metallic nanoparticles is a green alternative that reduces the toxicity of this nanomaterials and may enable a synergy between the metallic core and the biomolecules employed in the process enhancing biological activity. The aim of this study was to synthesize biogenic titanium nanoparticles using the filtrate of the fungus Trichoderma harzianum as a stabilizing agent, to obtain a potential biological activity against phytopathogens and mainly stimulate the growth of T. harzianum, enhancing its efficacy for biological control. RESULTS: The synthesis was successful and reproductive structures remained in the suspension, showing faster and larger mycelial growth compared to commercial T. harzianum and filtrate. The nanoparticles with residual T. harzianum growth showed inhibitory potential against Sclerotinia sclerotiorum mycelial growth and the formation of new resistant structures. A great chitinolytic activity of the nanoparticles was observed in comparison with T. harzianum. In regard to toxicity evaluation, an absence of cytotoxicity and a protective effect of the nanoparticles was observed through MTT and Trypan blue assay. No genotoxicity was observed on V79-4 and 3T3 cell lines while HaCat showed higher sensitivity. Microorganisms of agricultural importance were not affected by the exposure to the nanoparticles, however a decrease in the number of nitrogen cycling bacteria was observed. In regard to phytotoxicity, the nanoparticles did not cause morphological and biochemical changes on soybean plants. CONCLUSION: The production of biogenic nanoparticles was an essential factor in stimulating or maintaining structures that are important for biological control, showing that this may be an essential strategy to stimulate the growth of biocontrol organisms to promote more sustainable agriculture.

RESUMO

BACKGROUND: Although clinical practice guidelines recommend pain education as the first-line option for the management of chronic musculoskeletal pain, there is a lack of pain education programmes in healthcare. Thus, digital health programmes can be an effective tool for implementing pain education strategies for public health. This trial will aim to analyse the implementation and effectiveness outcomes of three online pain science education strategies in the Brazilian public health system (SUS) for individuals with chronic musculoskeletal pain. METHODS: We will conduct a hybrid type III effectiveness-implementation randomised controlled trial with economic evaluation. We will include adult individuals with chronic musculoskeletal pain, recruited from primary healthcare in the city of Guarapuava, Brazil. Individuals will be randomised to three implementation groups receiving a pain science education intervention (EducaDor) but delivered in different modalities: group 1) synchronous online; group 2) asynchronous videos; and group 3) interactive e-book only. Implementation outcomes will include acceptability, appropriateness, feasibility, adoption, fidelity, penetration, sustainability, and costs. We will also assess effectiveness outcomes, such as pain, function, quality of life, sleep, self-efficacy, and adverse effects. Cost-effectiveness and cost-utility analyses will be conducted from the SUS and societal perspectives. The evaluations will be done at baseline, post-intervention (10 weeks), and 6 months. DISCUSSION: This study will develop and implement a collaborative intervention model involving primary healthcare professionals, secondary-level healthcare providers, and patients to enhance self-management of chronic pain. In addition to promoting better pain management, this study will also contribute to the field of implementation science in public health by generating important insights and recommendations for future interventions. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05302180; 03/29/2022).

RESUMO

BACKGROUND: To translate and cross-culturally adapt into Brazilian-Portuguese, and to test the measurement properties of the following items of implementation outcome measures: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM). METHODS: This was a measurement properties study in accordance with the Consensus-based Standards for the selection of health status Measurement Instruments (COSMIN). We conducted a translation and cross-cultural adaptation of three implementation measures according to guidelines for translation and cross-cultural adaptation, then we collected information from patients who had participated in remotely delivered physical therapy treatment for musculoskeletal condition. The patients answered the translated versions of the implementation outcome measures. The measurement properties of the three implementation outcome measures were collected in a test-retest assessment, with an interval of 7 to 14 days.. The measurement properties evaluated in this study were interpretability, measured using Ceiling and Floor Effects, reliability in test-retest evaluation, measured using Cronbach's Alpha Coefficient, internal consistency, measured using Intraclass Correlation Coefficient and construct validity, measured using Pearson Correlation. RESULTS: We included 104 participants (76 female). The average age of the sample was 56.8 (SD 14.8) years old. The items of implementation outcome measures (AIM, IAM, and FIM) showed 66.39%, 63.11%, and 63.93% of ceiling effects. The items of implementation outcome measures showed adequate internal consistency measured using Cronbach's Alpha Coefficient (AIM: 0.89, IAM: 0.91, FIM: 0.93) and values of Standard Error of Measurement between 5 and 10%, showing good measurement error. The results of AIM and IAM was classified as moderate reliability and the FIM as substantial reliability. In a total 96 correlations, > 75% of correlations met our prior hypothesis. CONCLUSION: The three Brazilian-Portuguese versions of items of implementation outcome measures had adequate internal consistency, measurement error and construct validity. The three implementation outcome measures showed moderate to substantial reliability values. The Ceiling Effect was observed in the three measures, showing maximum values ​​in more than 15% of the evaluations.

RESUMO

Impairments in several domains of cognitive functions are observed in people with Type 2 Diabetes Mellitus (T2DM), often accompanied by low Brain-derived neurotrophic factor (BDNF) concentrations. Although aerobic and resistance exercise enhances cognitive functions and raises BDNF concentrations in several populations, it remained uncertain in T2DM subjects. This study compared the effects of a single bout of aerobic (AER, 40 min of treadmill walk at 90-95% of the maximum walk speed) or resistance (RES, 3 × 10 repetitions in eight exercises at 70% of 10-RM) exercise on specific cognitive domain performance and plasma BDNF concentrations of physically active T2DM subjects. Eleven T2DM subjects (9 women/2 men; 63 ± 7 years) performed two counterbalanced trials on non-consecutive days. Stroop Color and Word (SCW) task [assessing the attention (congruent condition) and inhibitory control (incongruent condition)], Visual response time (assessing the response time), and blood collection (for plasma BDNF concentrations) were performed pre and post-exercise sessions. With distinct magnitude, both AER and RES improved the incongruent-SCW (d = - 0.26 vs. - 0.43 in AER and RES, respectively; p < 0.05), RT(best) (d = - 0.31 vs. - 0.52, p < 0.05), and RT(1-5) (d = - 0.64 vs. - 0.21, p < 0.05). The congruent-SCW and RT(6-10) were not statistically different. Plasma BDNF concentrations were elevated 11% in AER (d = 0.30) but decreased by 15% in RES (d = - 0.43). A single session of aerobic or resistance exercise similarly improved the inhibitory control and response time of physically active T2DM subjects. Nevertheless, aerobic and resistance exercise sessions induced an opposite clinical effect in plasma BDNF concentrations.

RESUMO

BACKGROUND: In response to the COVID-19 pandemic, cancer centers rapidly adopted telehealth to deliver care remotely. Telehealth will likely remain a model of care for years to come and may not only affect the way oncologists deliver care to their own patients but also the physicians with whom they share patients. OBJECTIVE: This study aimed to examine oncologist characteristics associated with telehealth use and compare patient-sharing networks before and after the COVID-19 pandemic in a rural catchment area with a particular focus on the ties between physicians at the comprehensive cancer center and regional facilities. METHODS: In this retrospective observational study, we obtained deidentified electronic health record data for individuals diagnosed with breast, colorectal, or lung cancer at Dartmouth Health in New Hampshire from 2018-2020. Hierarchical logistic regression was used to identify physician factors associated with telehealth encounters post COVID-19. Patient-sharing networks for each cancer type before and post COVID-19 were characterized with global network measures. Exponential-family random graph models were performed to estimate homophily terms for the likelihood of ties existing between physicians colocated at the hub comprehensive cancer center. RESULTS: Of the 12,559 encounters between patients and oncologists post COVID-19, 1228 (9.8%) were via telehealth. Patient encounters with breast oncologists who practiced at the hub hospital were over twice as likely to occur via telehealth compared to encounters with oncologists who practiced in regional facilities (odds ratio 2.2, 95% CI 1.17-4.15; P=.01). Patient encounters with oncologists who practiced in multiple locations were less likely to occur via telehealth, and this association was statistically significant for lung cancer care (odds ratio 0.26, 95% CI 0.09-0.76; P=.01). We observed an increase in ties between oncologists at the hub hospital and oncologists at regional facilities in the lung cancer network post COVID-19 compared to before COVID-19 (93/318, 29.3%, vs 79/370, 21.6%, respectively), which was also reflected in the lower homophily coefficients post COVID-19 compared to before COVID-19 for physicians being colocated at the hub hospital (estimate: 1.92, 95% CI 1.46-2.51, vs 2.45, 95% CI 1.98-3.02). There were no significant differences observed in breast cancer or colorectal cancer networks. CONCLUSIONS: Telehealth use and associated changes to patient-sharing patterns associated with telehealth varied by cancer type, suggesting disparate approaches for integrating telehealth across clinical groups within this health system. The limited changes to the patient-sharing patterns between oncologists at the hub hospital and regional facilities suggest that telehealth was less likely to create new referral patterns between these types of facilities and rather replace care that would otherwise have been delivered in person. However, this study was limited to the 2 years immediately following the initial outbreak of COVID-19, and longer-term follow-up may uncover delayed effects that were not observed in this study period.

RESUMO

BACKGROUND: Given the rapid advances in communication technology and the need that emerged from the COVID-19 pandemic, telehealth initiatives have been widely used worldwide. This masterclass aims to provide an overview of telerehabilitation for musculoskeletal conditions, synthesizing the different terminologies used to describe telehealth and telerehabilitation, its effectiveness and how to use it in clinical practice, barriers and facilitators for the implementation in health services, and discuss the need of a curriculum education for the near future. MAIN BODY: Telerehabilitation refers to the use of information and communication technologies provided by any healthcare professionals for rehabilitation services. Telerehabilitation is a safe and effective option in the management of musculoskeletal conditions in different models of delivery. There are many technologies, with different costs and benefits, synchronous and asynchronous, that can be used for telerehabilitation: telephone, email, mobile health, messaging, web-based systems and videoconferences applications. To ensure a better practice of telerehabilitation, the clinician should certify safety and access, and appropriateness of environment, communication, technology, assessment, and therapeutic prescription. Despite the positive effect of telerehabilitation in musculoskeletal disorders, a suboptimal telerehabilitation implementation may have happened due to the COVID-19 pandemic, especially in countries where telehealth was not a reality, and clinicians lacked training and guidance. This emphasizes the need to identify the necessary curriculum content to guide future clinicians in their skills and knowledge for telerehabilitation. There are some challenges and barriers that must be carefully accounted for to contribute to a health service that is inclusive and relevant to health professionals and end users. CONCLUSIONS: Telerehabilitation can promote patient engagement in health care and plays an important role in improving health outcomes in patients with musculoskeletal conditions. Digital health technologies can also offer new opportunities to educate patients and facilitate the process of behavior change to a healthy lifestyle. Currently, the main needs in telerehabilitation are the inclusion of it in health curriculums in higher education and the development of cost-effectiveness and implementation trials, especially in low- and middle-income countries where access, investments and digital health literacy are limited.

RESUMO

Approximately 2.5 × 106 square kilometers of the Amazon forest are currently degraded by fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all remaining forests in the region. Carbon emissions from this degradation total up to 0.2 petagrams of carbon per year (Pg C year-1), which is equivalent to, if not greater than, the emissions from Amazon deforestation (0.06 to 0.21 Pg C year-1). Amazon forest degradation can reduce dry-season evapotranspiration by up to 34% and cause as much biodiversity loss as deforestation in human-modified landscapes, generating uneven socioeconomic burdens, mainly to forest dwellers. Projections indicate that degradation will remain a dominant source of carbon emissions independent of deforestation rates. Policies to tackle degradation should be integrated with efforts to curb deforestation and complemented with innovative measures addressing the disturbances that degrade the Amazon forest.

RESUMO

BACKGROUND: During the COVID-19 pandemic, telerehabilitation allowed the continuation of physical therapy care in parallel with public health measures to prevent the virus spread. However, in low- and middle-income countries including Brazil, telerehabilitation was unfamiliar to most of the population. OBJECTIVE: To investigate acceptability, preferences, and needs in telerehabilitation by Brazilian physical therapists and the general population. METHODS: We conducted an observational cross-sectional study with an online survey consisting of 13 multiple-choice items. Items were distributed among acceptability, preferences, and needs sections, and encompassed confidence in delivering or receiving telerehabilitation, its perceived efficacy and costs, and suitable content. RESULTS: A total of 1107 responses were registered, 717 from physical therapists. Half of them self-reported confidence in conducting telerehabilitation through the internet (synchronous or asynchronous). The same proportion disagreed that telerehabilitation is as effective as in-person interventions. Physical therapists agreed telerehabilitation should contain educational, self-management strategies, and exercises information, but the general population endorsed the provision of technical advice on exercise execution. The general population mostly reported that telerehabilitation could help their specific health condition (86%), but only 14% of respondents would pay the same as they pay for in-person consultations. Participants reported an overall preference for synchronous communication and concern about the lack of a hands-on approach. CONCLUSION: Physical therapists and the general population appear to demonstrate apprehension towards telerehabilitation. Insufficient preparation or inadequate knowledge might influence participants' acceptance, preferences, and needs.
