RESUMEN

Background: In amputees, exercising can impact the distribution of body temperature. The aim of this case report is to verify the acute effect of exercising in C-Mill on the temperature distribution in the lower limbs of a man with unilateral transfemoral amputation. Materials and Methods: The thigh and legs of a man with left distal transfemoral amputation were evaluated by thermography (infrared sensor FLIR T650sc) before and after a single 30-minute exercise session performed in a virtual reality treadmill device (C-Mill). Results: The thermographic evaluation showed a difference in temperature between the thighs both before and after the intervention. However, there was a decrease in asymmetry, which went from 4.0°C to 3.1°C in the anterior view and from 5.3°C to 2.9°C in the posterior view, after the intervention. Conclusion: Thermography allowed us to assess the difference in temperature in the lower limbs. Even though the temperature discrepancy has decreased after the single exercise session using the C-Mill, this difference persisted.

RESUMEN

OBJECTIVE: The incidence of spinal cord injury in Brazil is increasing. It is important to understand more about how individuals are living with spinal cord injury. DESIGN: Cross-sectional, observational study of individuals with spinal cord injury in south-eastern Brazil. SUBJECTS: A questionnaire with 125 questions was applied to individuals diagnosed with spinal cord injury. Participants were recruited by survey team from 2 rehabilitation centres (both in south-eastern Brazil) that treat persons diagnosed with SCI. Personal characteristics, associated health conditions, quality of life, work status, environmental factors, and other functioning-related aspects were evaluated. RESULTS: A total of 201 individuals participated in the survey. Of these, 79% were male, mean age 44 years, 60% were considered paraplegic, and the major causes of impairment were firearm injuries and road traffic accidents. Spasticity was the most frequently reported health condition, followed by neuropathic pain. 50% of subjects did not report any difficulty with participation in activities of daily living. However, only approximately 10% of subjects returned to work after spinal trauma. Their quality of life is reported 44% as good. CONCLUSION: Most people with spinal cord injury in south-eastern Brazil are male and paraplegic, health problems and spasticity is considered their most problematic health condition. Although they report having a good quality of life, they still encounter disabling environmental barriers that make their life more difficult, such as poor accessibility of public spaces, and only a small proportion (10%) returned to work after their injury. This study provides an initial overview of the lived experience of people with spinal cord injury in south-eastern Brazil and should serve as a starting point for future research on this population.

RESUMEN

Several circulating miRNAs identified in the plasma of smokers have been implicated as promoters of nasopharyngeal and lung carcinoma. To investigate the plasma profile of miRNAs in subjects who reduces the number of smoked cigarettes and who quit after six months. We accompanied 28 individuals enrolled in a Smoking Cessation Program over 6 months. At Baseline, clinical characteristics, co-morbidities, and smoking history were similar among subjects. After 6 months, two groups were defined: who successfully quitted smoking (named "quitters", n = 18, mean age 57 years, 11 male) and who reduced the number of cigarettes smoked (20-90%) but failed to quit smoking (named "smokers", n = 10, mean age 52 years, 3 male). No significant clinical changes were observed between groups at baseline and after a 6-month period, however, quitters showed significant downregulations in seven miRNAs at baseline: miR-17 (- 2.90-fold, p = 0.029), miR-20a (- 3.80-fold, p = 0.021); miR-20b (- 4.71-fold, p = 0.027); miR-30a (- 3.95-fold, p = 0.024); miR-93 (- 3.63-fold, p = 0.022); miR-125a (- 1.70-fold, p = 0.038); and miR-195 (- 5.37-fold, p = 0.002), and after a 6-month period in 6 miRNAs: miR-17 (- 5.30-fold, p = 0.012), miR-20a (- 2.04-fold, p = 0.017), miR-20b (- 5.44-fold, p = 0.017), miR-93 (- 4.00-fold, p = 0.041), miR-101 (- 4.82-fold, p = 0.047) and miR-125b (- 3.65-fold, p = 0.025). Using time comparisons, only quitters had significant downregulation in miR-301b (- 2.29-fold, p = 0.038) after 6-month. Reductions in the number of smoked cigarettes was insufficient to change the plasma profile of miRNA after 6 months. Only quitting smoking (100% reduction) significantly downregulated miR-301b related to hypoxic conditions, promotion of cell proliferation, decreases in apoptosis, cancer development, and progression as increases in radiotherapy and chemotherapy resistance.

RESUMEN

OBJETIVO: Investigar o perfil de miRNAs em indivíduos participantes de um grupo de cessação ao tabagismo. MÉTODOS: Caracterizamos os mecanismos de defesa das vias aéreas por meio do transporte mucociliar (TMC) e avaliamos a expressão de miRNAs no plasma de indivíduos que participaram do Grupo de Cessação ao Tabagismo do Instituto Dante Pazzanese de Cardiologia (n=28, idade média 56 anos), após seis meses eles foram divididos em 2 grupos: aqueles que obtiveram sucesso na cessação (Cessadores, n=18, idade média 57 anos, 11 homens) e aqueles que reduziram a exposição ao cigarro (20-90%) porém continuaram fumando (Tabagistas, n=10, três homens). RESULTADOS: Na avaliação basal, as características clínicas, co-morbidades, histórico de tabagismo e carga tabágica foram semelhantes entre os grupos. Observamos que os tabagistas apresentaram TMC prolongado e que a cessação do tabagismo induziu à normalização do TMC. Comparando os Cessadores com os Tabagistas, sete miRNAs foram regulados negativamente: miR-17 (-2. 90-fold, p=0. 029), miR-20a (-3. 80-fold, p=0. 021); miR-20b (-4. 71-fold (p=0. 027); miR-30a (-3. 95-fold, p=0. 024); miR-93 (-3. 63-fold, p=0. 022); miR-125a (-1. 70-fold, p=0. 038); and miR-195 (-5. 37-fold, p=0. 002). Após seis meses, seis miRNAs foram diferentemente expressos com regulação negativa nos Cessadores em relação aos Tabagistas: miR-17 (-5. 30-x, p=0. 012), miR-20a (-2. 04f-x, p=0. 017), miR-20b (-5. 44-x, p=0. 017), miR-93 (-4. 00-x, p=0. 041), miR-101 (-4. 82-x, p=0. 047) e miR-125b (-3. 65-x, p=0. 025). Entretanto, somente o grupo de Cessadores apresentou após 6 meses, regulação negativa significantdo miR-301b (-2. 29-x, p=0. 038). CONCLUSÃO: Muitos MiRNAs que foram identificados no plasma de tabagistas têm sido associados ao desenvolvimento de carcinoma na sofaríngeo e câncer de pulmão. A redução da carga tabágica não foi suficiente para alterar esse perfil de expressão dos miRNAs. Somente a cessação do tabagismo promoveu regulação negativa do miR-301b que está relacionado com condições de hipóxia, de promoção da proliferação celular, da inibição do apoptose e aumento da resistência à quimioterapia. Descritores: microRNAs; Fumar; Abandono do hábito de fumar; Neoplasias pulmonares; Inflamação; Biomarcadores.

RESUMEN

Restaurar a capacidade de andar é um dos objetivos da reabilitação na lesão medular incompleta (LMI). O treino orientado a tarefa abrange os princípios do aprendizado motor, envolvendo mecanismos de neuroplasticidade central e, consequentemente, reorganização cortical. O treinamento da marcha robótica G-EO System (GS) atua como um reforço da prática repetitiva e específica das fases da marcha. Objetivo: Investigar os efeitos combinados da fisioterapia e da terapia robótica na funcionalidade da marcha em relação ao equilíbrio e velocidade da marcha em pacientes com LMI. Métodos: Estudo de coorte retrospectivo com 14 pacientes na fase crônica da doença, que realizaram 20 sessões de GS associado à fisioterapia convencional (FC). Utilizamos o Teste de Caminhada de 10 Metros (TC10) e a Escala de Equilíbrio de Berg (EEB). Valores de p <0,05 foram considerados estatisticamente significativos pelo teste de Wilcoxon ao início da fisioterapia convencional e pré e pós intervenção. Resultados: Observou-se que no TC10, a velocidade inicial média variou de 2,60 m/s ± 1,72 no início da FC a 1,57 m/s ± 0,80 no final das 20 sessões de GS com p = 0,0424. Para a EEB no início da FC, a média foi de 31,85 pontos ± 12,50 e 42,35 ± 14,25 ao final da intervenção, com p = 0,0096. Conclusão: A terapia robótica da marcha associada à FC mostrou-se eficaz na promoção do equilíbrio e da melhora da velocidade da marcha em indivíduos na fase crônica da LMI.

Restoring the ability to walk, especially independently, is one of the goals in the rehabilitation of patients with incomplete spinal cord injury (ISCI). The G-EO System (GS) robotic gait training acts as a reinforcer of the repetitive and specific practice of the gait phases. Objective: Investigate the combined effects of physiotherapy and robotic therapy on gait functionality in relation to balance and gait speed in patients with ISCI. Methods: Retrospective cohort study with 14 patients in the chronic phase of the disease, using the GS as a robotic intervention for gait and stairs, consisting of a 20-session protocol associated with conventional physical therapy. We used the 10-meter Walk Test (10WT) and the Berg Balance Scale (BBS). P values <0.05 were considered statistically significant using the Wilcoxon test at the beginning of conventional physical therapy and before and after intervention. Results: At the 10WT, the mean initial velocity ranged from 2.60 m/s ± 1.72 at the beginning of conventional physical therapy to 1.57 m/s ± 0.80 at the end of the 20 GS sessions with p = 0.0424. For BBS at the beginning of conventional physical therapy, the average was 31.85 points ± 12.50, and 42.35 ± 14.25 at the end of the 20 GS sessions, with p = 0.0096. Conclusions: Robotic gait therapy associated with conventional physiotherapy has been shown to be effective in promoting balance and gait speed improvement in individuals in the chronic phase after involvement of incomplete spinal cord injury.

RESUMEN

Objetivo: Apresentar características do perfil de indivíduos amputados unilaterais na fase pré protética atendidos em um instituto de reabilitação hospitalar. Método: Estudo retrospectivo a partir dos registros dos prontuários dos pacientes amputados do Instituto de Medicina Física e Reabilitação da Universidade de São Paulo que realizaram reabilitação hospitalar na instituição. Foram analisados os prontuários de julho de 2015 até novembro de 2018. Nestes prontuários foram coletadas as informações sobre: idade, gênero, tipo de lesão, tempo da lesão, etiologia da lesão, mobilidade funcional por meio do teste Timed Up and Go (TUG), equilíbrio/funcionalidade por meio do teste Amputee Mobility Predictor (AMP), capacidade de caminhar por meio do teste de caminhada de 2 minutos (TC2Min). Análises descritivas foram feitas para avaliar as características demográficas e clínicas dos pacientes. Resultados: A média de idade foi de 43,59±16,52 anos, com tempo de amputação de 21,9±32,7 meses. Houve predominância do gênero masculino e a etiologia traumática e amputação transfemoral foram as mais prevalentes. Os dados clínicos encontrados foram: tempo de execução do teste TUG: 18,7 segundos, da AMP: 31,2 pontos, TC2Min: 111,2 metros. Conclusão: Na fase pré-protética, a origem traumática foi predominante, sendo a maioria do gênero masculino. A amputação transfemoral foi superior às demais. O tempo médio da amputação até a internação é quase de dois anos. Os testes clínicos embora apresentem bons resultados, mostram a necessidade de serem aprimoradas as questões como, por exemplo, a mobilidade funcional que é condizente com risco de quedas nestes indivíduos.

Objective: To present characteristics of the profile of unilateral amputees in the pre-prosthetic phase treated at a hospital rehabilitation institute. Method: A retrospective study based on medical records of amputated patients of the Institute of Physical Medicine and Rehabilitation of the University of São Paulo who underwent hospital rehabilitation at the institution. The medical records from July 2015 to November 2018 were analyzed. Information on: age, gender, type of injury, time of injury, etiology of the injury, functional mobility by the Timed Up and Go (TUG) test was collected, balance/functionality through the Amputee Mobility Predictor (AMP) test, ability to walk through the 2-minute walk test (TC2Min). Descriptive analyzes were performed to evaluate the demographic and clinical characteristics of the patients. Results: The mean age was 43.59 ± 16.52 years, with amputation time of 21.9 ± 32.7 months. There was a predominance of males and traumatic etiology and transfemoral amputation were the most prevalent. The clinical data found were: TUG test execution time: 18.7 seconds, AMP: 31.2 points, TC2Min: 111.2 meters. Conclusion: In the pre-prosthetic phase, the traumatic origin was predominant, most of them male. Transfemoral amputation was superior to the others. The average time from amputation to hospitalization is almost two years. Clinical tests, although successful, show the need to improve issues such as functional mobility that is commensurate with the risk of falls in these individuals

RESUMEN

OBJECTIVE: The aim of the present study was to assess nasal mucociliary clearance, mucus properties and inflammation in smokers and subjects enrolled in a Smoking Cessation Program (referred to as quitters). METHOD: A total of 33 subjects with a median (IQR) smoking history of 34 (20-58) pack years were examined for nasal mucociliary clearance using a saccharine transit test, mucus properties using contact angle and sneeze clearability tests, and quantification of inflammatory and epithelial cells, IL-6 and IL-8 concentrations in nasal lavage fluid. Twenty quitters (mean age: 51 years, 9 male) were assessed at baseline, 1 month, 3 months and 12 months after smoking cessation, and 13 smokers (mean age: 52 years, 6 male) were assessed at baseline and after 12 months. Clinicaltrials.gov: NCT02136550. RESULTS: Smokers and quitters showed similar demographic characteristics and morbidities. At baseline, all subjects showed impaired nasal mucociliary clearance (mean 17.6 min), although 63% and 85% of the quitters demonstrated significant nasal mucociliary clearance improvement at 1 month and 12 months, respectively. At 12 months, quitters also showed mucus sneeze clearability improvement (∼26%), an increased number of macrophages (2-fold) and no changes in mucus contact angle or cytokine concentrations. CONCLUSION: This study showed that smoking cessation induced early improvements in nasal mucociliary clearance independent of mucus properties and inflammation. Changes in mucus properties were observed after only 12 months of smoking cessation.
