Application of the ICU Mobility Scale in patients submitted to cardiac surgery / Aplicação da ICU Mobility Scale em pacientes submetidos à cirurgia cardíaca

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.

Lactate dehydrogenase as a hematopoietic stem cell mobilization biomarker in autologous transplantation

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.

INTRODUCTION: The role of the physiotherapist through early mobilization aims to reduce the adverse effects of immobility and improve functionality. In this sense, the use of functional scales is crucial to assess the functional condition of critically ill patients. OBJECTIVE: To analyze the knowledge of intensive care physiotherapists about functional scales, to know the most used scales and the main barriers to applicability in the ICU, in addition to associating the use of functional scales with safety and the perception of results. MATERIALS AND METHODS: This is a cross-sectional and quantitative study carried out with intensive care physiotherapists in the city of Fortaleza between August 2022 and February 2023. Data were collected via an online questionnaire (Google Forms). The data were analyzed using the Jamovi Software. Descriptive statistics and the Chi-square test were used. RESULTS: 75 physiotherapists participated, most with 1 to 5 years of experience in the intensive care unit. Most professionals perceive benefits in the use of functional scales and use them to prescribe conduct with safety in its applicability, with the Intensive Care Unit Mobility Scale being the most used. As for the barriers that most interfere with the use of functional scales, they were related to the team, the patient and the institution. CONCLUSION: Many physiotherapists are aware of the objectives and benefits of using functional scales, they say they are confident in applying them in their practice, and the IMS scale is the one most used by professionals. The interaction between the physiotherapist and the team was the main barrier to the application of functional scales in the Intensive Care Unit.

Early mobilization after total hip or knee arthroplasty: a substudy of the POWER. 2 study

Abstract Background Early mobilization after surgery is a cornerstone of the Enhanced Recovery After Surgery (ERAS) programs in total hip arthroplasty (THA) or total knee arthroplasty (TKA). Our goal was to determine the time to mobilization after this surgery and the factors associated with early mobilization. Methods This was a predefined substudy of the POWER.2 study, a prospective cohort study conducted in patients undergoing THA and TKA at 131 Spanish hospitals. The primary outcome was the time until mobilization after surgery as well as determining those perioperative factors associated with early mobilization after surgery. Results A total of 6093 patients were included. The median time to achieve mobilization after the end of the surgery was 24 hours [16-30]. 4,222 (69.3%) patients moved in ≤ 24 hours after surgery. Local anesthesia [OR = 0.80 (95% confidence interval [CI]: 0.72-0.90); p= 0.001], surgery performed in a self-declared ERAS center [OR = 0.57 (95% CI: 0.55-0.60); p< 0.001], mean adherence to ERAS items [OR = 0.93 (95% CI: 0.92-0.93); p< 0.001], and preoperative hemoglobin [OR = 0.97 (95% CI: 0.96-0.98); p< 0.001] were associated with shorter time to mobilization. Conclusions Most THA and TKA patients mobilize in the first postoperative day, early time to mobilization was associated with the compliance with ERAS protocols, preoperative hemoglobin, and local anesthesia, and with the absence of a urinary catheter, surgical drains, epidural analgesia, and postoperative complications. The perioperative elements that are associated with early mobilization are mostly modifiable, so there is room for improvement.

Study on the effect of early mobilization in oral cancer patients who have undergone free flap reconstruction / 中国实用护理杂志

Objective:To explore an early mobilization plan for oral cancer patients after free flap reconstruction and evaluate the application effect of the plan.Methods:This study was a prospective randomized controlled trial. A total of 173 patients undergoing free flap reconstruction surgery from December 2018 to December 2021 in the second ward of Peking University School and Hospital of Stomatology were selected. The patients were randomly divided into the control group (87 cases) and the intervention group (86 cases) by cluster randomized grouping. The control group received the routine nursing plan, that was, head immobilization for 4 days after surgery, and patients performed sat up and off-bed activity on the 5th day. The intervention group received the early mobilization plan, that was, patients sat up on the 2nd day after surgery and performed off-bed activity on the 3rd day. The incidence of vascular compromise, postoperative complications, sleep time in the first 5 days after surgery, catheter removal time, hospitalization duration and expenses were compared between the two groups.Results:The incidence of postoperative pulmonary infection, the daily sleep time in the first 5 days after surgery, the time for removing nasogastric tube, trachea cannula, and urinary catheter were 7.0%(6/86), (5.0 ± 1.0) h/d, (11.8 ± 7.3) d, (6.1 ± 3.2) d, (3.6 ± 0.6) d in the intervention group, and 13.8%(12/87), (4.4 ± 1.3) h/d, (14.2 ± 5.8) d, (7.3 ± 1.7) d, (4.0 ± 0.9) d in the control group, all differences were statistically significant ( χ2 = 3.89, t values were -3.57 - -2.44, all P<0.05). There was no significant difference in the incidence of rascular compromise, hospitalization duration and expenses between the two groups (all P>0.05). Conclusions:For patients undergoing free tissue flap reconstruction, it is safe to sit up on the 2nd day and get out of bed on the 3rd day, which can reduce the incidence of pulmonary infection, improve patient sleep, and shorten the indwelling time of nasogastric tube, trachea cannula and urinary catheter.

The Awareness, Practice and Perception of InstrumentAssisted Soft Tissue Mobilization (IASTM) among Malaysian Physiotherapists

@#Introduction: Instrument-assisted soft tissue mobilization (IASTM) is a relatively recent method that has been shown to help reduce muscular tension, increase flexibility and prevent tissue adhesion. Nevertheless, there is a paucity of awareness and knowledge about the benefits of IASTM, especially following injury rehabilitation, despite its many advantages. The study aimed to investigate the awareness, practice and perception of instrument- assisted soft tissue mobilization (IASTM) among Malaysian physiotherapists (PTs). Methods: The cross-sectional study included 133 PTs who answered an online questionnaire via a google link on their awareness and perception of IASTM in their practice. The Google link was given to the participants through email and the official Malaysian Physiotherapy (MPA) social media group. Results: Majority of the respondents (73.7%) are aware of IASTM technique. Despite being aware on IASTM, 74.4% of respondents reported not practicing the technique. Furthermore, 73.7% of respondents stated that the main reason they don’t practice is because fingers have better force adjustment than IASTM. Over 80% of respondents revealed that practicing IASTM can save energy and convenient during myofascial release. Moreover, 82.7 % of respondents stated that one of the benefits of IASTM for PTs is that it helps alleviate stress on fingers and wrists during soft tissue mobilization. Beyond 55% of respondents stated that they will incorporate IASTM in practice in near future. Conclusion: According to the findings, the majority of Malaysian physiotherapists are aware of the IASTM. However, fewer than half of respondents declined to incorporate it into their future practice due to the PTs preference for feeling the patient’s muscle texture. More emphasis can be given to the IASTM techniques among the PTs as the participants have mentioned that IASTM has better force exertion and saves energy when applying soft tissue massage.

Expression Changes of Hypoxia-Inducible Factor-1α in G-CSF Induced Hematopoietic Stem Cell Mobilization / 中国实验血液学杂志

OBJECTIVE@#To investigate the expression and its relative mechanism of hypoxia-inducible factor-1α(HIF-1α) in bone marrow(BM) of mice during G-CSF mobilization of hematopoietic stem cells (HSC) .@*METHODS@#Flow cytometry was used to detect the proportion of Lin-Sca-1+ c-kit+ (LSK) cells in peripheral blood of C57BL/6J mice before and after G-CSF mobilization. And the expression of HIF-1α and osteocalcin (OCN) mRNA and protein were detected by RQ-PCR and immunohistochemistry. The number of osteoblasts in bone marrow specimens of mice was counted under the microscope.@*RESULTS@#The proportion of LSK cells in peripheral blood began to increase at day 4 of G-CSF mobilization, and reached the peak at day 5, which was significantly higher than that of control group (P<0.05). There was no distinct difference in the expression of HIF-1α mRNA between bone marrow nucleated cells and osteoblasts of steady-state mice (P=0.073), while OCN mRNA was mainly expressed in osteoblasts, which was higher than that in bone marrow nucleated cells (P=0.034). After mobilization, the expression level of HIF-1α increased, but OCN decreased, and the number of endosteum osteoblasts decreased. The change of HIF-1α expression was later than that of OCN and was consistent with the proportion of LSK cells in peripheral blood.@*CONCLUSION@#The expression of HIF-1α in bone marrow was increased during the mobilization of HSC mediated by G-CSF, and one of the mechanisms may be related to the peripheral migration of HSC induced by osteoblasts inhibition.

Efficiency and safety analysis of Plerixafor combined with granulocyte colony-stimulating factor on autologous hematopoietic stem cell mobilization in lymphoma / 中华血液学杂志

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

Among the adverse effects, there was an unsatisfactory ventilatory muscle pattern (7.1%), peripheral oxygen saturation less than 90% (4.8%), and changes in blood pressure (7.1%). There was no record of changes in heart rate, accidental extubation or loss of venous access during mobilizations, as well as changes in hemodynamic, respiratory and oxygenation behavior before, during and after mobilization were not observed. Conclusion: physical exercises proved to be safe, viable in any clinical environment, respecting safety limits, and may bring potential benefits to patients admitted to the ICU (AU).

Effectiveness of Early Mobilization in Prevention and Rehabilitation of Functional Impairment After Myocardial Revascularization Surgery: A Systematic Review

Abstract Introduction Myocardial revascularization surgery is associated with high morbidity and mortality, due to factors like the general anesthesia and the surgical procedure itself. Physiotherapy, combined with early mobilization (EM), can provide the patient with better functional parameters. Objective To review, identify and describe the effectiveness of EM in the prevention and rehabilitation of functional parameters of coronary artery bypass graft surgery. Methodology This is a systematic review conducted between February 2020 and 2021 of randomized clinical trials (RCTs) published in the Cochrane databases Library, LILACS, Scielo and Medline / PubMed. The Physiotherapy Evidence Database (PEDro) scale was used for assessment of the methodological quality of studies included. Results Four studies were reviewed. Two articles assessed functional capacity, one using the cycle ergometer and one with inspiratory muscle training (IMT) together with active exercises and early walking. One article reported a reduction in the incidence of atelectasis and pleural effusion with EM and one article reported improvements in the alveolus-artery gradient and inspiratory muscle power using an inspiratory muscle trainer combined with EM. Conclusion EM is effective in the prevention and rehabilitation of functional parameters after CABG surgery, by improving functional capacity, respiratory muscle power, quality of life and gas exchange, and reducing the incidence of atelectasis and pleural effusion.

Qualitative systematic review of the safety and feasibility of early mobilization in critically ill patients with femoral catheters / 中国胸心血管外科临床杂志

@#Objective    To investigate the safety and feasibility of early mobilization in critically ill patients with femoral catheters, and to provide reference for guiding clinical rehabilitation training. Methods    The literature on the safety and feasibility of early mobilization in critically ill patients with femoral catheters included in PubMed, EMbase, OVID, Springer-link, Wiley Online Library, and Web of Science up to June 2021 was searched, and relevant data were extracted for analysis. Results    Seventy-two papers were initially screened, and 12 papers that met the criteria were finally included, covering 1 056 patients, and 489 patients had femoral catheters. Patients underwent 6 495 sessions of physical therapy, and a total of 62 patients had adverse events, including 14 (2.86%, 14/489) patients with catheter-related adverse events. Conclusion    Although early mobilization in critically ill patients with femoral catheters may lead to adverse catheter-related events, the incidence is low. Therefore, the associated risks and benefits should be weighed in clinical practice, and femoral catheter is not recommended as a contraindication for early mobilization in critically ill patients.

Peripheral blood stem cells collection in pediatric patients with thalassemia major weighing 20 kilogram or less / 中国输血杂志

【Objective】 To evaluate the safety and efficacy of the collection of peripheral blood stem cells (PBSCs) in pediatric patients with thalassemia major (TM) weighing 20 kg or less. 【Methods】 PBSCs collection data of 170 pediatric patients with TM weighing 20 kg or less from January 2013 to December 2020 in our center were reviewed. Safety was assessed by the occurrence of adverse events during apheresis procedures, and efficacy was evaluated by the number of CD34+ cells collected. 【Results】 A total of 171 PBSCs procedures were performed on 170 patients with TM weighing 20 kg or less, with a median age of (4.98±1.53) years and a median weight of (17.30±2.18) kg. The probability of collecting at least 1×106 CD34+ cells/kg during a single course of apheresis was 99.41% (169/170), with a median (5.88±4.23) ×106 CD34+ cells collected per kg of weight of the recipient. A minimum pre-apheresis hemoglobin (Hb) of 60 g/L in patients with TM weighing 20 kg or less was safe and feasible. The most common adverse event of G-CSF mobilization in TM patients is bone pain, with the incidence of 7.65% (13/170), which was higher than that of healthy children donors in our center. The most common adverse events during the collection were pain at the puncture site of the femoral vein (6.47%, 11/170) and low pressure of the fluid (2.92%, 5/170). And no serious complications related to PBSCs mobilization, central venous catheter(CVC)placement or the apheresis procedure occurred. 【Conclusion】 PBSCs collection by COM.TEC blood cell separator in children weighing 20 kg or less is safe and efficacious.

Carboxylesterase 1 family knockout alters drug disposition and lipid metabolism

The mammalian carboxylesterase 1 (Ces1/CES1) family comprises several enzymes that hydrolyze many xenobiotic chemicals and endogenous lipids. To investigate the pharmacological and physiological roles of Ces1/CES1, we generated Ces1 cluster knockout (Ces1 -/- ) mice, and a hepatic human CES1 transgenic model in the Ces1 -/- background (TgCES1). Ces1 -/- mice displayed profoundly decreased conversion of the anticancer prodrug irinotecan to SN-38 in plasma and tissues. TgCES1 mice exhibited enhanced metabolism of irinotecan to SN-38 in liver and kidney. Ces1 and hCES1 activity increased irinotecan toxicity, likely by enhancing the formation of pharmacodynamically active SN-38. Ces1 -/- mice also showed markedly increased capecitabine plasma exposure, which was moderately decreased in TgCES1 mice. Ces1 -/- mice were overweight with increased adipose tissue, white adipose tissue inflammation (in males), a higher lipid load in brown adipose tissue, and impaired blood glucose tolerance (in males). These phenotypes were mostly reversed in TgCES1 mice. TgCES1 mice displayed increased triglyceride secretion from liver to plasma, together with higher triglyceride levels in the male liver. These results indicate that the carboxylesterase 1 family plays essential roles in drug and lipid metabolism and detoxification. Ces1 -/- and TgCES1 mice will provide excellent tools for further study of the in vivo functions of Ces1/CES1 enzymes.

Comparison between the effects of Maitland’s mobilization versus its combination with vastus medialis oblique neuromuscular stimulation on two scales (NPRS & WOMAC) in knee osteoarthritis patients

Background & objectives: Osteoarthritis (OA) is the most common form of arthritis that increases with age affecting the population from the middle age to the elderly. The present study was undertaken to find whether neuromuscular stimulation of vastus medialis oblique (VMO) in combination with Maitland’s mobilization and exercises was more effective as compared to Maitland’s mobilization with exercises alone in patients with knee OA. Methods: Sixty patients with knee OA were purposively selected and randomly distributed to two groups that received an intervention for eight weeks. Group A patients received Maitland’s mobilization in combination with exercises and group B patients received the same intervention as group A in combination with neuromuscular stimulation of VMO muscle. After eight weeks, outcome measures, i.e. Numeric Pain Rating Scale (NPRS) and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) index, were reassessed. Results: Both groups showed significant (P<0.05) within-group improvement in the knee pain levels and stiffness as reflected by NPRS and WOMAC index. Interpretation & conclusions: Patients of both the groups (A and B) were found to be improving significantly in pain and disability, group A patients receiving Maitland’s mobilization in combination with exercises were found to get more relief in pain and disability.

Effects of Myofascial Mobilization on Flexibility in Young Men Adults / Efeito da Mobilização Miofascial na Flexibilidade em Homens Adultos Jovens

The aim of the study is to control the effect of myofascial mobilization on flexibility values ​​in young men. 23 young adult men, aged between 18 and 30 years (74.8 ± 9.8 kg; 1.74 ± 0.06 cm; 24.7 ± 3.0 kg/m2), participated in the study, separated into experimental and control groups. Participants of the experimental group received an instrument assisted soft-tissue mobilization (IASTM) session, bilateral, in the muscular region of the quadriceps femoris, hamstrings and triceps surae. The rectus femoris, vastus lateralis and medial, biceps femoris, semitendinosus, semimembranosus, gastrocnemius and soleus muscles were mobilized for a period of 60 seconds. In the control session, participants remained at rest for a period of 15 minutes. The flexibility assessments were performed pre- and- immediately, 24 hours, and 48 hours post-sessions of both groups. The myofascial mobilization session promoted percentage increases in flexibility significantly higher at 24 hours when compared to values ​​immediately after, 24 hours and 48 hours after the control session (P < 0.05). The percentage increases in flexibility 48 hours after the myofascial mobilization session were significantly greater when compared to values ​​immediately post and 24 hours after the control session (P < 0.05). The findings of the present study suggest that an instrument assisted soft-tissue mobilization (IASTM) session promotes increases in flexibility in young adults one and two days after the intervention.

O objetivo do presente estudo foi verificar o efeito da mobilização miofascial nos valores da flexibilidade em homens jovens. Participaram do estudo 23 homens adultos jovens, com idade entre 18 e 30 anos (74,8 ± 9,8 kg; 1,74 ± 0,06 cm; 24,7 ± 3,0 kg/m2), separados em grupo experimental e controle. Os participantes do grupo experimental receberam uma sessão mobilização miofascial assistida por instrumento (IASTM), bilateralmente, na região muscular do quadríceps femural, isquiotibiais e tríceps sural. Os músculos reto femural, vasto lateral e medial, bíceps femoral, semitendinoso, semimembranoso, gastrocnêmio e sóleo foram mobilizados por um período de 60 segundos. Na sessão controle, os participantes permaneceram em repouso por um período de 15 minutos. As avaliações da flexiblidade foram realizadas pré, imediatamente após, 24 horas e 48 horas após as sessões de ambos os grupos. A sessão de mobilização miofascial promoveu aumentos percentuais da flexibilidade 24 horas significativamente maiores quando comparado aos valores imediatamente pós, 24 horas e 48 horas da sessão controle (P < 0,05). Os aumentos percentuais da flexibilidade 48 horas após a sessão mobilização miofascial foram significativamente maiores quando comparado aos valores imediatamente pós e 24 horas da sessão controle (P < 0,05). Os achados do presente estudo sugerem que uma sessão de mobilização miofascial assistida por instrumento promove aumentos da flexibilidade em adultos jovens após um e dois dias à intervenção.(AU)

The Effectiveness of Early Investigative Tools for Neural Lesions in Leprosy: An Observational Cohort Study

Leprosy can cause different lesions in peripheral nerves and inervatory structures. This study aims to analyze the effectiveness of evaluation protocols used to identify neural lesions in leprosy, such as Degree of Physical Disability (DPD), Simplified Neurological Assessment (SNA) and propose to use Neuro Dynamic Assessment (NDA). A descriptive analytical study was carried out in 27 individuals treated in two outpatient leprosy clinics in São Paulo State, between 2017 and 2019. A control group of age and sex matched 27 people, chosen from the population without a diagnosis of leprosy, was also evaluated. The Mann-Whitney, Multivariate Linear Regression, association between variables, and P<0.05 values were used. The test that most captured the neurological alterations was the SNA, with 22 (81.5%) in the upper limbs (ULs) and 25 (92.6%) in the lower limbs (LLs), followed by the NDA, with 20 (74.1%) in the ULs and 11 (40.7%) in the LLs. The DPD showed handicap in the hands of 16 (59.2%) individuals and in the feet of 17 (62.9%) individuals. The three assessment instruments can and should be used in combination to expand the monitoring of neural lesions in leprosy, as there are changes that are not perceptible with one instrument but can be confirmed by another. If there is an instrument to be chosen, it should be the SNA, because it identifies subtle changes that suggest neural distress.

DNA methylation is involved in the microRNA-886-3p gene expression and plays a potential role in hematopoietic stem and progenitor cell mobilization through affecting SDF-1

The role of the sympathetic nervous system (SNS) in hematopoietic stem and progenitor cell (HSPC) mobilization has been largely investigated. However, there is a critical need for the identification of the underlying contributing factors to improve HSPC yield for transplantation. It has been demonstrated that miR-886-3p targets stromal-derived factor-1 (SDF-1), the central mediator of mobilization, and therefore may play a part in this process. Besides, miR-886-3p expression can be epigenetically regulated through DNA methylation modifications inits gene promoter. Here, to assess the contribution of miR-886-3p and other epigenetic factors in HSPC mobilization, human bone marrow-derived mesenchymal stem cells (MSCs) were treated with the ?-adrenergic agonist of isoprenaline. The expression of miR-886-3p and SDF-1and the gene promoter methylation status of this miRNA were then respectively evaluated through the appropriate PCR techniques. As expected, despite a transient initial increase in SDF-1mRNA level, its expression reduced, and miR-886-3plevel remarkably increased 48 h following treatment. The gene promoter methylation pattern of miR-886-3p also changed from a full methylated state to a partially methylated one. Together, our findings suggest that miR-886-3p can be epigenetically regulated and through suppressing the expression of SDF-1 play an active role in the SNS-mediated HSPC mobilization.

El antifujimorismo y la defensa de la democracia: estudio sobre la conciencia política de jóvenes movilizados contra el fujimorismo en Lima / The anti-fujimorism and the defense of democracy: a study on the political consciousness of young people mobilized against fujimorism in Lima

Resumen El objetivo del presente estudio es explorar las dimensiones de conciencia política en jóvenes que participaron en movilizaciones sociales contra el fujimorismo entre el 2016 y 2018. El grupo de participantes estuvo constituido por 8 jóvenes (6 hombres y 2 mujeres) de entre 21 y 29 años. Para lograr el objetivo se utilizó una guía de entrevista a profundidad semiestructurada basada en las dimensiones de conciencia política de Sandoval (2001). Las entrevistas se realizaron durante el periodo de indulto a Alberto Fujimori y la prisión preventiva a Keiko Fujimori (entre julio y noviembre de 2018). Los resultados muestran que las 7 dimensiones permiten entender el proceso de conciencia política que experimenta el colectivo antifujimorista. La principal dimensión es la de identidad colectiva, dado la alta vinculación de los participantes con el colectivo antifujimorista estos se encuentran altamente identificados con las normas, conductas y objetivos del mismo.

Abstract The objective of this study is to explore the dimensions of political awareness in young people who participated in social mobilizations against fujimorism between 2016 and 2018. The group of participants consisted of 8 young people (6 men and 2 women) between 21 and 29 years old. To achieve the objective, a semi-structured in-depth interview guide was based on the dimensions of political consciousness of Sandoval (2001). The interviews were conducted during the pardon period for Alberto Fujimori and the preventive detention for Keiko Fujimori (between July and November 2018). The results show that the 7 dimensions allow us to understand the process of political consciousness experienced by the anti-Fujimori collective. The main dimension is that of collective identity. Given the high bond of the participants with the anti-Fujimori collective, they are highly identified with its norms, behaviors and objectives.
