RESUMO

Macauba (Acrocomia aculeata) is a Brazilian palm tree whose oil in the pulp is rich in oleic acid and carotenoids. However, its physiological function remains unknown. This study aimed to investigate the effects of macauba pulp oil (MPO) on the metabolic link between lipid metabolism and lifespan using Caenorhabditis elegans (C. elegans). C. elegans were treated with 5.0 mg/mL of MPO for analyzing triglyceride and glycerol accumulation, fatty acid profile, gene expression of lipid and oxidative metabolism proteins under cold (4°C) stress conditions, and lifespan analysis under stress conditions such as cold (4°C), heat (37°C), and oxidative (paraquat) stress. MPO significantly suppressed fat accumulation and increased glycerol (a lipolysis index) and the lifespan of C. elegans at low temperature (4°C). This was accompanied by decreased mRNA levels of the genes involved in lipogenesis (spb-1 and pod-2) and increased levels of the genes involved in fatty acid ß-oxidation (acs-2 and nhr-49) and fat mobilization genes (hosl-1 and aak-2). Additionally, MPO treatment modulated fatty acid pools in C. elegans at low temperatures in that MPO treatment decreased saturated fatty acid levels and shifted the fatty acid profile to long-chain fatty acids. Moreover, the effect of MPO on fat accumulation at low temperatures was abolished in fat-7 mutants, whereas both fat-1 and fat-7 contribute, at least in part, to MPO-elevated survival of C. elegans under cold conditions. PRACTICAL APPLICATION: The results obtained in the present study may contribute to the understanding of the health benefits of consuming macauba pulp oil and consequently stimulate economic growth and the industrial application of this new type of oil, which may result in the creation of new jobs and increased value of small producers.

RESUMO

Obesity has become increasingly prevalent in the intensive care unit, presenting a significant challenge for healthcare systems and professionals, including rehabilitation teams. Caring for critically ill patients with obesity involves addressing complex issues. Despite the well-established and safe practice of early mobilization during critical illness, in rehabilitation matters, the diverse clinical disturbances and scenarios within the obese patient population necessitate a comprehensive understanding. This includes recognizing the importance of metabolic support, both non-invasive and invasive ventilatory support, and their weaning processes as essential prerequisites. Physiotherapists, working collaboratively with a multidisciplinary team, play a crucial role in ensuring proper assessment and functional rehabilitation in the critical care setting. This review aims to provide critical insights into the key management and rehabilitation principles for obese patients in the intensive care unit.

RESUMO

High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improved 5-year overall survival rates in relapsed/refractory germ cell tumors (GCTs) from 10% to 52%. Nearly 30% of GCT patients are deemed poor mobilizers after receiving several lines of prior therapy. There is limited data available regarding upfront plerixafor use in GCT patients. We predicted upfront plerixafor use would increase the amount of stem cells collected preventing subsequent mobilizations and improve time to curative therapy. A retrospective, single center, chart review of adult GCT patients who received plerixafor upfront for mobilization at a single center between January 1, 2013 and August 31, 2021 was performed. The primary objective was to evaluate the rate of successful peripheral blood CD34+ cell collections. Secondary objectives consisted of describing the impact of plerixafor use on mobilization and assessing auto-HSCT related outcomes. Sixteen patients received plerixafor upfront after an average of three prior lines of therapy (range: 2-5 lines). Successful collection (≥4 × 106 CD34+ cells/Kg collected within four days) was achieved in 15 (94%) patients in a median of one apheresis day (interquartile range: 1-2 days). All patients proceeded to an initial auto-HSCT and 12 patients (75%) completed both transplants as planned. Survival at 12 months was 50%. The significantly higher amount of CD34+ cells collected over less apheresis days demonstrated the clinical utility of upfront plerixafor and its potential to facilitate more efficient stem cell mobilization. There is a need for larger randomized studies with upfront plerixafor use in this unique patient population.

RESUMO

Respiratory physiotherapy, including the management of invasive mechanical ventilation (MV) and noninvasive mechanical ventilation (NIV), is a key supportive intervention for critically ill patients. MV has potential for inducing ventilator-induced lung injury (VILI) as well as long-term complications related to prolonged bed rest, such as post-intensive care syndrome and intensive care unit acquired weakness. Physical and respiratory therapy, developed by the critical care team, in a timely manner, has been shown to prevent these complications. In this pathway, real-time bedside monitoring of changes in pulmonary aeration and alveolar gas distribution associated with postural positioning, respiratory physiotherapy techniques and changes in MV strategies can be crucial in guiding these procedures, providing safe therapy and prevention of potential harm to the patient. Along this path, electrical impedance tomography (EIT) has emerged as a new key non-invasive bedside strategy free of radiation, to allow visualization of lung recruitment. This review article presents the main and potential applications of EIT in relation to physiotherapy techniques in the ICU setting.

RESUMO

OBJECTIVE: The aim of this scoping review was to investigate the mobilization dose reporting in the randomized clinical trials (RCTs) of patients receiving mechanical ventilation in the intensive care unit. METHODS: In this scoping review, RCTs published from inception to December 2022 were searched in relevant electronic databases. Trials that involved adults receiving mechanical ventilation (>48 hours) and any early mobilization modality were analyzed. Two independent authors screened, selected, and extracted data. The mobilization doses of the intervention groups (IGs) and the comparator groups (CGs) were assessed as the proportion of reported items/total applicable from the main items of the Consensus on Exercise Reporting Template (CERT). RESULTS: Twenty-three RCTs comprising 2707 patients (1358 from IG and 1349 from CG) were included, involving studies on neuromuscular electrical stimulation (n = 7), progressive mobility (n = 6), leg cycling (n = 3), tilt table (n = 1), and multicomponent (n = 6) mobilization. The pooled reporting of CERT items was 68% (86% for IG and 50% for CG). The most reported CERT items were type of exercise (100%) and weekly frequency (100%) for IG, whereas the least reported were intensity (4%) and individualization (22%) for CG. Regardless of the group, individualization, progression, and intensity of mobilization were the least reported items. Eight IGs (35%) reported all CERT items, whereas no CGs reported all of them. CONCLUSIONS: Deficits in mobilization dose reporting of intensive care unit RCTs were identified, especially for exercise intensity in adults receiving mechanical ventilation. One-third of IG reported all exercise dosing items, whereas no CG reported all of them. Future studies should investigate the details of optimal dosage reporting, particularly for CG. IMPACT: The lack of dose reporting may partially explain the inconsistency in the meta-analysis results of early mobilization trials, thus limiting the interpretation for clinical practice in the intensive care unit.

RESUMO

INTRODUCTION: Inpatient rehabilitation is extremely important for patients recovering from cardiac surgery. Although a walking diary is routinely used in clinical practice, it has yet to be adequately tested and reported in the literature. OBJECTIVES: To establish whether the use of a walking diary affects the number of steps taken following cardiac surgery and whether this is related to the patient's level of cardiac anxiety. METHODS: An open, controlled, randomized clinical trial was conducted with adult patients submitted to elective valve and/or coronary surgery, who had no motor impairment. All the participants used a pedometer to register the number of steps taken over five consecutive days in the hospital. Twenty-nine individuals were randomized to create an intervention group that used the walking diary as treatment strategy, while twenty-three were allocated to a control group. The Mann-Whitney test was used to compare the number of steps between the two groups, while Spearman's correlation coeficiente was performed to evaluate the relationship between the number of steps and the level of cardiac anxiety. Statistical significance was defined as p<0.05. RESULTS: The groups were similar regarding their demographic, clinical and surgical characteristics. There was no difference between the groups regarding the total number of steps taken: control group=1,496 (477.5 - 2992.5) vs. Intervention group=1,468.5 (494.2 - 2,678) (p=0.902). CONCLUSION: The use of the walking diary had no effect on the number of steps taken and was unassociated with the level of cardiac anxiety in inpatients following cardiac surgery.

INTRODUÇÃO: A reabilitação hospitalar é extremamente importante para pacientes em recuperação de cirurgia cardíaca. Embora o diário de caminhada seja rotineiramente utilizado na prática clínica, ele ainda não foi adequadamente testado e relatado na literatura. OBJETIVOS: Estabelecer se o uso do diário de caminhada afeta o número de passos dados após cirurgia cardíaca e se isso está relacionado ao nível de ansiedade cardíaca do paciente. MÉTODOS: Foi realizado um ensaio clínico aberto, controlado e randomizado com pacientes adultos submetidos à cirurgia eletiva de valva e/ou coronária, sem comprometimento motor. Todos os participantes usaram um pedômetro para registrar o número de passos dados ao longo de cinco dias consecutivos de internação. Vinte e nove indivíduos foram randomizados para um grupo intervenção para usar o diário de caminhada como estratégia de tratamento, enquanto vinte e três foram alocados para um grupo controle. O teste de Mann-Whitney foi utilizado para comparar o número de passos entre os dois grupos, enquanto o coeficiente de correlação de Spearman foi realizado para avaliar a relação entre o número de passos e o nível de ansiedade cardíaca. A significância estatística foi definida como p < 0,05. RESULTADOS: Os grupos foram semelhantes quanto às características demográficas, clínicas e cirúrgicas. Não houve diferença entre os grupos quanto ao número total de passos dados: grupo controle=1.496 (477,5 - 2.992,5) vs. grupo intervenção=1.468,5 (494,2 - 2.678) (p=0,902). CONCLUSÃO: O uso do diário de caminhada não teve efeito no número de passos dados e não foi associado ao nível de ansiedade cardíaca em pacientes internados após cirurgia cardíaca.

RESUMO

Neurocritical patients (NCPs) in the intensive care unit (ICU) rapidly progress to respiratory and peripheral muscle dysfunctions, which significantly impact morbidity and death. Early mobilization in NCPs to decrease the incidence of ICU-acquired weakness has been showing rapid growth, although pertinent literature is still scarce. With this review, we summarize and discuss current concepts in early mobilization of critically ill patients within the context of neurologic pathology in NCPs. A narrative synthesis of literature was undertaken trying to answer the following questions: How do the respiratory and musculoskeletal systems in NCPs behave? Which metabolic biomarkers influence physiological responses in NCPs? Which considerations should be taken when prescribing exercises in neurocritically ill patients? The present review detected safety, feasibility, and beneficial response for early mobilization in NCPs, given successes in other critically ill populations and many smaller intervention trials in neurocritical care. However, precautions should be taken to elect the patient for early care, as well as monitoring signs that indicate interruption for intervention, as worse outcomes were associated with very early mobilization in acute stroke trials.

RESUMO

The germination and post-seminal development of Arecaceae are notably complex due to the microscopic dimensions of the embryonic axis, the occurrence of dormancy, and the diversity of reserve compounds. In-depth information on this subject is still limited, especially in terms of the basal sub-family Calamoideae. Mauritiella armata is widely distributed in the Amazon region and is considered a key species in flooded ecosystems (veredas) in the Cerrado biome. We sought to describe histogenesis and reserve compound dynamics during the germination of M. armata, as well as the changes in incubated seeds over time. Seeds with their operculum removed (the structure that limits embryonic growth) were evaluated during germination using standard methods of histology, histochemistry, and electron microscopy. Evaluations were also performed on intact seeds incubated for 180 days. The embryos show characteristics associated with recalcitrant seeds of Arecaceae: a high water content (>80%), differentiated vessel elements, and reduced lipid reserves. Both the embryo and endosperm store abundant reserves of proteins, neutral carbohydrates, and pectins. The completion of germination involves cell divisions and expansions in specific regions of the embryo, in addition to the mobilization of embryonic and endospermic reserves through symplastic and apoplastic flows. Intact seeds show dormancy (not germinating for 180 days), but exhibit continuous development associated with cell growth, differentiation, and reserve mobilization. The anatomical and histochemical characters of M. armata seeds indicate an association between recalcitrance and dormancy related to the species' adaptation to flooded environments.

RESUMO

Abstract Introduction Early mobilization is an alternative used in the Intensive Care Unit (ICU) to reduce the effects of immobility. The Intensive Care Unit Mobility Score (IMS) is applied to assess mobility status. Objective To determine the functional level of ICU patients submitted to cardiac surgery using the IMS scale. Methods This is an analytical observational study carried out with adult ICU patients submitted to cardiac surgery. Data on the use of vasoactive drugs, functional level through IMS, duration of mechanical ventilation and length of ICU stay were collected from the physiotherapy routine form and recorded on a specific instrument developed for the study. The data obtained from the IMS scale score on the postoperative days in the ICU were used to classify the patients' mobility during the hospitalization period. Descriptive statistics were used to present the data. Results A total of 69 patients were evaluated, 43% of whom were men, and all had an SMI of 0 on the first postoperative day. Classification on the scale increased over the course of hospitalization (IMS between 7 and 10), despite the use of vasoactive drugs in 54.6% of the individuals. Conclusion Patients submitted to cardiac surgery admitted to the ICU had moderate-to-high mobility levels throughout their stay and at discharge from the ICU.

Resumo Introdução A mobilização precoce é uma alternativa utilizada em Unidades de Terapia Intensiva (UTIs) na tentativa de reduzir os efeitos decorrentes do imobilis-mo.

RESUMO

Resumo Revisitaremos uma constelação de respostas para garantir justiça reprodutiva para mulheres e meninas durante a crise do Zika no Brasil. As ações relatadas foram conduzidas pela Anis - Instituto de Bioética, uma ONG feminista. Argumentamos que, durante as emergências sanitárias, é necessário o uso de lentes feministas interseccionais para construir respostas efetivas e sensíveis às questões de gênero, em favor de mulheres e meninas. Apresentamos três táticas de incidência utilizadas na luta por justiça reprodutiva durante a crise do Zika: 1) construir narrativas baseadas em histórias de vida que retratem os efeitos desproporcionais da crise em mulheres e meninas; 2) produzir dados baseados em evidências para catalisar estratégias de incidência para revisão legal e de políticas públicas; 3) promover oportunidades para o fortalecimento de alianças e movimentos, bem como o compartilhamento de poder por meio de atividades de mobilização comunitária. Reconhecemos a importância de responder às necessidades das populações em tempo real, e para isso torna-se fundamental que as evidências sobre os impactos das emergências em saúde pública sejam produzidas e compartilhadas de maneira ágil. Os esforços em incidência não são estratégias fragmentadas, pois garantir a justiça reprodutiva exige uma estrutura abrangente e transformadora, incluindo soluções que envolvam o cotidiano das pessoas comuns e suas experiências de vida.

Abstract This article aims to revisit a constellation of responses to guarantee reproductive justice for women and girls during the Zika crisis in Brazil, that were conducted by Anis - Institute of Bioethics, a Brazilian feminist NGO. We argue that intersectional feminist lenses and gender-sensitive responses are necessary to build effective efforts for women and girls during a public health emergency. As such, we present three concomitant and intersectional learned tactics we used to fight for reproductive justice during the Zika crises, but also in its aftermath: 1. To build storytelling narratives that portray the disproportional effects of the crisis on women and girls; 2. To produce evidence-based data to catalyze advocacy strategies for legal and policy review; 3. To promote movement building opportunities and sharing power through community mobilization activities. We assume the importance of providing immediate evidence and gender sensitive framings to inform real-time public health responses. Advocacy efforts should not be seen as fragmented strategies, since ensuring reproductive justice demands a comprehensive and transformative framework that include solutions for multiple aspects of real-life experiences.

RESUMO

O presente artigo explora alguns impactos políticos e sociais reconhecidos nos dez anos que sucederam as manifestações de junho de 2013, dando ênfase a um fator específico: o papel das mídias sociais no cenário político e na mobilização de grupos. Partindo desse foco, trata da possibilidade de que tais ferramentas digitais possam ser melhor exploradas por certos grupos políticos em detrimento de outros, e os motivos para tanto. Tal questão será discutida a partir de autores de estudos da tecnologia, da teoria social e da psicanálise. Não necessariamente inferindo uma diferenciação de conteúdo de ideologias políticas, propomos essa distinção considerando que os impactos subjetivos e de mobilização produzidos por tais mídias podem ser assimilados e empregados de acordo com objetivos específicos. Trata-se, assim, de um exame sobre os impactos que as mídias sociais produzem em processos de subjetivação e de agrupamento, e seus efeitos políticos.

Resumos This paper explores political and social impacts present in the ten years since June 2013 demonstrations, emphasizing an specific factor: the role of social media in the political landscape and in mobilizing groups. We take as a central question the possibility that those digital tools are better explored by some political groups to the detriment of others, and the reasons that explain this difference. This question is developed with authors from the studies of technology, social theory, and psychoanalysis. Without necessarily assuming a content differentiation among political views, we propose their distinction considering that the subjective and the mobilizing impacts produced by these media can be assimilated and employed according to specific objectives. Therefore, this study is an examination of the impacts that social media produce on subjectivation and grouping processes, and their political effects.

Cet article explore certains des impacts politiques et sociaux constatés au cours des dix années qui ont suivi les manifestations de juin 2013, en mettant l'accent sur un facteur spécifique: le rôle des médias sociaux dans le paysage politique et dans la mobilisation des groupes. À partir de là, il aborde la possibilité que ces outils numériques puissent être mieux exploités par certains groupes politiques au détriment d'autres, et les raisons de cette différence supposée. Cette question sera discutée à l'aide d'auteurs issus des études technologique, de la théorie sociale et de la psychanalyse. Sans nécessairement en déduire une différenciation dans le contenu des opinions politiques, nous proposons cette distinction en considérant que les impacts subjectifs et mobilisateurs produits par ces médias peuvent être assimilés et utilisés en fonction d'objectifs spécifiques. Il s'agit donc d'examiner les impacts que les médias sociaux produisent sur les processus de subjectivation et de regroupement, et leurs effets politiques.

Para discutir esta cuestión se utiliza autores de la filosofía de la tecnología, de la teoría social y del psicoanálisis. Sin asumir necesariamente una diferenciación de contenido entre ideologías políticas, se propone esta distinción teniendo en cuenta que los impactos subjetivos y de movilización que producen estas herramientas digitales pueden ser asimilados y empleados de acuerdo con objetivos específicos.

RESUMO

BACKGROUND/OBJECTIVES: Joint and muscle overloads commonly occur in extreme conditioning programs (ECP), which require great physical fitness for their practice. For its execution, good functional performance, mobility and adequate movement patterns are required. The fascial system plays a fundamental role in performance in ECP and one of the techniques used to improve joint mobility and movement pattern is the self-myofascial release using a foam roller (FR). Our objective of this study was to evaluate the effect of FR in ankle dorsiflexion (DF) range of motion (ROM), assessed with the Lunge Test, and also in the squat movement pattern, assessed using the Technique smartphone application, in ECP practitioners. METHODS: The study was carried out with 18 ECP practitioners who practiced for over four months and had a mean age of 30.94 years. The participants were randomized and allocated into two groups: control and intervention. The FR was self-applied bilaterally in the sural triceps region for 90 seconds. Tests to assess DF ROM and squat movement pattern were applied before and immediately after using FR (intervention group) or after three-minute rest (control group). RESULTS: The use of the FR promoted an immediate increase in ankle DF ROM during the Lunge Test and during the squat and a decrease in dynamic knee valgus during the squat. CONCLUSION: The FR can be used as a tool for an acute increase in DF ROM and a decrease in dynamic knee valgus, having a positive impact in improving movement patterns.

RESUMO

BACKGROUND: Shoulder pain is a disabling musculoskeletal disorder worldwide. Thus, it is important to identify interventions able to improve pain and disability. OBJECTIVE: To investigate the effects of mobilization with movement (MWM) on pain, disability, and range of motion in patients with shoulder pain and movement impairment. METHODS: A systematic search of different databases was performed. The systematic review protocol has been registered in PROSPERO (CRD42023404128). A random-effects model for meta-analysis was used to determine the mean difference (MD), standardized mean differences (SMD), and 95% confidence interval for the outcome of interest. RESULTS: Twenty-six studies were included. Of these, eighteen were included in the meta-analysis. MWM improved pain during movement with a moderate effect SMD of (-0.6; 95% confidence interval, -1.1 to -0.1, I2 = 0%; N = 66;) and shoulder abduction MD of (12.7°; 1.3 to 24.0; I2 = 73%; N = 90) compared to sham MWM in the short term (0-6 weeks). Combined MWM and conventional rehabilitation improved pain at rest, with a MD of (-1.2; -2.2 to -0.2; I2 = 61%; N = 100), and disability SMD of (-1.3; confidence interval -2.2 to -0.4; I2 = 87%; N = 185) compared to conventional rehabilitation alone in the short term. Combined MWM and conventional rehabilitation also resulted in improvement in shoulder abduction and external rotation. Compared to Maitland, MWM resulted in improvement in the shoulder abduction MD (20.4°; confidence interval 4.3 to 36.5; I2 = 89%; N = 130) in the short term. There is no information regarding long-term effects. CONCLUSION: Evidence suggests that MWM may reduce shoulder pain and restore shoulder range of motion and function. Our findings are promising, but the evidence is not strong enough to recommend it pragmatically.

RESUMO

ABSTRACT Introduction: Pre-apheresis peripheral blood CD34+ cell count (PBCD34+) is the most important predictor of good cell mobilization before hematopoietic stem cell transplantation, albeit flow cytometry is not always immediately available. Identification of surrogate markers can be useful. The CD34+ cells proliferate after mobilization, resulting in elevated lactate dehydrogenase (LDH) activity and correlating with the PBCD34+ count. Objective: To determine the LDH cut-off value at which adequate CD34+ cell mobilization is achieved and its diagnostic yield. Materials and methods: A total of 103 patients who received an autologous stem cell transplantation (ASCT) between January 2015 and January 2020 were included. Demographic and laboratory characteristics were obtained, including complete blood count, pre-apheresis PBCD34+ and LDH levels. Receiver operating characteristic (ROC) curves were performed to identify the optimal serum LDH activity cut-off points for ≥ 2 and ≥ 4 × 106 cells/kg post-mobilization CD34+ count and their diagnostic yield. Results: A post-mobilization serum LDH cut-off value of 462 U/L yielded a sensitivity (Se) = 86.8% (positive predictive value [PPV] = 72.7%), a pre- and post-mobilization serum LDH difference cut-off value of 387 U/L, an Se = 45.7% (PPV = 97%) and an LDH ratio of 2.46, with an Se = 47.1% (PPV = 97%) for an optimal mobilization count (CD34+ ≥ 4 × 106). Conclusion: The LDH measurement represents a fast and affordable way to predict PBCD34+ mobilization in cases where flow cytometry is not immediately available. According to the LDH diagnostic yield, it could be used as a surrogate marker in transplant centers, supporting the CD34+ count, which remains the gold standard.

RESUMO

Autologous hematopoietic stem cell transplantation (Auto-HSCT) is widely used in the treatment of patients with hematological neoplasms. Since these cells circulate in small quantities in the periphery, the use of regimens that promote their mobilization is essential. In this study, we retrospectively evaluated the efficacy and safety of using intermediate doses of cytarabine (1.6 g/m²) + filgrastim (10 mcg/kg/day) in the mobilization of stem cells in 157 patients treated by the Unified Health System at the Hematology and Bone Marrow Transplant Service of the Hospital Real Português de Beneficência, in Recife, Pernambuco. The sample included patients with multiple myeloma (MM) (58.6 %), lymphomas (29.9 %), and other neoplasms (11.5 %). The target of 2.0 × 10 6 CD34+ cells/kg was achieved by 148 (94.3 %) patients, in most cases (84.1 %) in a single apheresis and the median number of cells collected was 9.5 × 10 6 CD34+ cells/kg. No episode of febrile neutropenia was observed, however, 79 patients (50.3 %) required platelet transfusion (no cases attributed to bleeding). The median engraftment time was 11 days. Given these results, we suggest that the use of intermediate doses of cytarabine, combined with filgrastim, is safe and effective in mobilizing hematopoietic stem cells (HSCs).

RESUMO

BACKGROUND: Immersive virtual reality (VR) is an innovative strategy for inpatient rehabilitation programs. Using immersive VR in early mobilization protocols has not yet been investigated in the setting of hospitalized patients with acute decompensated heart failure (ADHF), especially to improve perceived dyspnea, a common symptom of heart failure (HF). METHODS: This is a single-center parallel superiority randomized clinical trial. The study will be conducted at a public teaching hospital in Brazil from January 2023 to January 2024. The sample will include adult patients with ADHF hospitalized for at least 24 h, randomly assigned in a 1:1 ratio to the control (standard early mobilization protocol conducted in the intensive care unit (ICU)) or intervention group (the same standard early mobilization protocol but associated with immersive VR). The primary outcome will be assessing perceived dyspnea, and the secondary outcome will be assessing patient experience. DISCUSSION: Using immersive VR in early mobilization protocols in the ICU is expected to improve perceived dyspnea in patients with ADHF as well as patient experience regarding care. This study has the potential to increase patient adherence to early mobilization protocols in the setting of ADHF as well as to promote a positive patient experience. Filling this gap could promote the rational incorporation of technologies in health care. TRIAL REGISTRATION: This study protocol is in its first version. CLINICALTRIALS: gov NCT05596292. Registered on 1 December 2022.

RESUMO

BACKGROUND: The endoplasmic reticulum (ER) contacts endosomes in all parts of a motor neuron, including the axon and presynaptic terminal, to move structural proteins, proteins that send signals, and lipids over long distances. Atlastin (Atl), a large GTPase, is required for membrane fusion and the structural dynamics of the ER tubules. Atl mutations are the second most common cause of Hereditary Spastic Paraplegia (HSP), which causes spasticity in both sexes' lower extremities. Through an unknown mechanism, Atl mutations stimulate the BMP (bone morphogenetic protein) pathway in vertebrates and Drosophila. Synaptic defects are caused by atl mutations, which affect the abundance and distribution of synaptic vesicles (SV) in the bouton. We hypothesize that BMP signaling, does not cause Atl-dependent SV abnormalities in Drosophila. RESULTS: We show that atl knockdown in motor neurons (Atl-KD) increases synaptic and satellite boutons in the same way that constitutively activating the BMP-receptor Tkv (thick veins) (Tkv-CA) increases the bouton number. The SV proteins Cysteine string protein (CSP) and glutamate vesicular transporter are reduced in Atl-KD and Tkv-CA larvae. Reducing the activity of the BMP receptor Wishful thinking (wit) can rescue both phenotypes. Unlike Tkv-CA larvae, Atl-KD larvae display altered activity-dependent distributions of CSP staining. Furthermore, Atl-KD larvae display an increased FM 1-43 unload than Control and Tkv-CA larvae. As decreasing wit function does not reduce the phenotype, our hypothesis that BMP signaling is not involved is supported. We also found that Rab11/CSP colocalization increased in Atl-KD larvae, which supports the concept that late recycling endosomes regulate SV movements. CONCLUSIONS: Our findings reveal that Atl modulates neurotransmitter release in motor neurons via SV distribution independently of BMP signaling, which could explain the observed SV accumulation and synaptic dysfunction. Our data suggest that Atl is involved in membrane traffic as well as formation and/or recycling of the late endosome.
