Effects of high- and moderate-intensity exercise on central hemodynamic and oxygen uptake recovery kinetics in CHF-COPD overlap

The oxygen uptake (V˙O2) kinetics during onset of and recovery from exercise have been shown to provide valuable parameters regarding functional capacity of both chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients. To investigate the influence of comorbidity of COPD in patients with CHF with reduced ejection fraction on recovery from submaximal exercise, 9 CHF-COPD male patients and 10 age-, gender-, and left ventricle ejection fraction (LVEF)-matched CHF patients underwent constant-load exercise tests (CLET) at moderate and high loads. The V˙O2, heart rate (HR), and cardiac output (CO) recovery kinetics were determined for the monoexponential relationship between these variables and time. Within-group analysis showed that the recovery time constant of HR (P<0.05, d=1.19 for CHF and 0.85 for CHF-COPD) and CO (P<0.05, d=1.68 for CHF and 0.69 for CHF-COPD) and the mean response time (MRT) of CO (P<0.05, d=1.84 for CHF and 0.73 for CHF-COPD) were slower when moderate and high loads were compared. CHF-COPD patients showed smaller amplitude of CO recovery kinetics (P<0.05) for both moderate (d=2.15) and high (d=1.07) CLET. Although the recovery time constant and MRT means were greater in CHF-COPD, CHF and CHF-COPD groups were not differently affected by load (P>0.05 in group vs load analysis). The ventilatory efficiency was related to MRT of V˙O2 during high CLET (r=0.71). Our results suggested that the combination of CHF and COPD may further impair the recovery kinetics compared to CHF alone.

Effect of Leap Motion-based 3D Immersive Virtual Reality Usage on Upper Extremity Function in Ischemic Stroke Patients / Efeito do uso imersivo da realidade virtual 3D baseada em movimento de salto na função de extremidade superior em pacientes com AVC isquêmico

ABSTRACT Immersive virtual reality (VR) is a technology that provides a more realistic environmental design and object tracking than ordinary VR. The aim of this study was to investigate the effectiveness of immersive VR on upper extremity function in patients with ischemic stroke. Sixty-five patients with ischemic stroke were included in this randomized, controlled, double-blind study. Patients were randomly divided into VR (n = 33) and control (n = 32) groups. The VR group received 60 minutes of the upper extremity immersive VR rehabilitation program and the control group received 45 minutes of conventional therapy and 15 minutes of a sham VR program. Rehabilitation consisted of 18 sessions of therapy, three days per week, for six weeks. The outcome measures were the Action Research Arm Test (ARAT), Functional Independence Measure (FIM), Fugl-Meyer Upper Extremity Scale (FMUE) and Performance Assessment of Self-Care Skills (PASS). In both the VR and control groups all parameters except the PASS improved over time. However independent t-test results showed that all of the FMUE, ARAT, FIM and PASS scores were significantly higher in the VR group compared with the control (p < 0.05). The minimal clinically important difference (MCID) scores of the FMUE and ARAT were higher than the cut-off MCID scores described in the literature in the VR group, whereas the FIM scores were below the cut-off MCID scores. All scores in the control group were below the cut-off scores. Immersive VR rehabilitation appeared to be effective in improving upper extremity function and self-care skills, but it did not improve functional independence.

RESUMO A VR imersiva é uma tecnologia que fornece design ambiental e rastreamento de objetos mais realistas do que a VR comum. O objetivo deste estudo foi investigar a eficácia da VR imersiva na função da extremidade superior em pacientes com AVC isquêmico. Sessenta e cinco pacientes com AVC isquêmico foram incluídos neste estudo randomizado, controlado e duplo-cego (clinictrials.gov. ID: NCT03135418). Os pacientes foram divididos aleatoriamente em VR (n = 33) e controle (n = 32). O grupo VR recebeu 60 minutos do programa de reabilitação imersiva da extremidade superior e o grupo controle recebeu 45 minutos de terapia convencional e 15 minutos de um programa falso de VR. A reabilitação consistiu em 18 sessões de terapia, 3 dias por semana, durante 6 semanas. As medidas de resultado foram Teste de braço de pesquisa-ação (ARAT), Medida de independência funcional (FIM), Escala de extremidades superiores de Fugl-Meyer (FMUE) e Avaliação de desempenho de habilidades de autocuidado (PASS). Nos grupos VR e controle, todos os parâmetros, exceto o PASS, melhoraram com o tempo. No entanto, os resultados dos testes t independentes mostraram que todos os escores FMUE, ARAT, FIM e PASS foram significativamente maiores no grupo VR em comparação ao controle (p <0,05). Os escores de FMUE e ARAT de diferença minimamente clinicamente importante (MCID) foram maiores que os pontos de corte de MCID descritos na literatura no grupo VR, enquanto os escores de FIM estiveram abaixo dos pontos de corte de MCID. Todas as pontuações no grupo controle estiveram abaixo das pontuações de corte. A reabilitação imersiva da VR parece ser eficaz para melhorar a função da extremidade superior e as habilidades de autocuidado, mas não melhora a independência funcional.

Factors affecting urinary continence and sexual potency recovery after robotic-assisted radical prostatectomy

ABSTRACT Introduction Robot-assisted radical prostatectomy (RARP) is the most recent surgical technique for localized prostate cancer. The Da Vinci (Intuitive Surgical, Sunnyvale, CA) system was first introduced in Brazil in 2008, with a fast growing number of surgeries performed each year. Objective Our primary endpoint is to analyze possible predictors of functional outcomes, related to patient and tumor features. As secondary endpoint, describe functional outcomes (urinary continence and sexual potency) from RARP performed in the Sírio-Libanês Hospital (SLH), a private institution, in São Paulo, from April 2008 to December 2015. Materials and Method Data from 104 consecutive patients operated by two surgeons from the SLH (MA and SA) between 2008 and 2015, with a minimum 12 months follow-up, were collected. Patient features (age, body mass index - BMI, PSA, date of surgery and sexual function), tumor features (tumor stage, Gleason and surgical margins) and follow-up data (time to reach urinary continence and sexual potency) were the variables collected at 1, 3, 6 and 12 month and every 6 months thereafter. Continence was defined as the use of no pad on medical interview and sexual potency defined as the capability for vaginal penetration with or without fosphodiesterase type 5 inhibitors. Results Mean age was 60 years old and mean BMI was 28.45 kg/m2. BMI >30kg/m2 (p<0.001) and age (p=0.011) were significant predictors for worse sexual potency after surgery. After 1, 3, 6 and 12 months, 20.7%, 45.7%, 60.9% and 71.8% from patients were potent, respectively. The urinary continence was reached in 36.5%, 80.3%, 88.6% and 92.8% after 1, 3, 6 and 12 months, respectively. Until the end of the study, only one patient was incontinent and 20.7% were impotent. Conclusion Age was a predictor of urinary and erectile function recovery in 12 months. BMI was significant factor for potency recovery. We obtained in a private hospital good functional results after 12 months of follow-up.

Comparison of long-term functional results between standard supracricoid laryngectomy and modified technique with sternohyoid muscle / Comparação de resultados funcionais a longo prazo entre laringectomia padrão supracricoide e técnica modificada com músculo esterno-hióideo

Abstract Introduction: Laryngeal cancer is the most common cancer of the upper respiratory tract. The main methods of treatment included surgery (partial laryngectomy and total laryngectomy) and radiation therapy. Laryngeal dysfunction is seen after both treatment modalities. Objective: The aim of the study is to compare postoperative functional results of the standard supracricoid partial laryngectomy technique and a modified supracricoid partial laryngectomy technique using the sternohyoid muscle. Methods: In total, 29 male patients (average years 58.20 ± 9.00 years; range 41-79 years) with laryngeal squamous cell carcinoma who underwent supra cricoid partial laryngectomy were included. The patients were divided into two groups in terms of the surgical techniques. In Group A, all patients underwent standard supracricoid partial laryngectomy technique between January 2007 and November 2011. In Group B, all patients underwent modified supracricoid partial laryngectomy between August 2010 and November 2011. Fiberoptic endoscopic evaluation of swallowing test, short version of the voice handicap index scores, and the MD Anderson dysphagia inventory, the time of oral feeding and the decanulation of the patients after surgery of each groups were compared. Results: The mean maximum phonation time was 8.68 ± 4.21 s in Group A and 15.24 ± 6.16 s in Group B (p > 0.05). The S/Z (s/s) ratio was 1.23 ± 0.35 in Group A and 1.08 ± 0.26 in Group B (p > 0.05); the voice handicap index averages were 9.86 ± 4.77 in Group A and 12.42 ± 12.54 in Group B (p > 0.05); the fiberoptic endoscopic evaluation of swallowing test averages were calculated as 12.73 ± 3.08 in Group A and 13.64 ± 1.49 in Group B (p > 0.05). In the MD Anderson dysphagia inventory, evaluation of swallowing, the emotional, physical, and functional scores were 29.21 ± 4.11, 32.21 ± 6.85, and 20.14 ± 2.17 in the Group B, and 29.20 ± 2.54, 32.4 ± 4.79, and 19 ± 1.92 in Group A, respectively. Conclusion: Although there is no statistical difference in functional outcome comparisons, if rules are adhered to in preoperative patient selection, modified supracricoid partial laryngectomy can be applied safely and meaningful gains can be achieved in functional outcomes.

Resumo Introdução: O câncer laríngeo é o câncer mais comum do trato respiratório superior. Os principais métodos de tratamento incluem cirurgia (laringectomia parcial e laringectomia total) e radioterapia. A disfunção laríngea é observada em ambas as modalidades de tratamento. Objetivos: Comparar os resultados funcionais pós-operatórios da técnica de laringectomia padrão supracricoide e a técnica de laringectomia supracricoide modificada com o uso do músculo esterno-hióideo. Método: Foram incluídos 29 pacientes do sexo masculino (média de 58,20 ± 9,00 anos, intervalo de 41 a 79) com carcinoma espinocelular de laringe submetidos à laringectomia supracricoide parcial. Os pacientes foram divididos em dois grupos em termos de técnicas cirúrgicas. Todos os pacientes do Grupo A foram submetidos à laringectomia padrão supracricoide entre janeiro de 2007 e novembro de 2011. No Grupo B, todos os pacientes foram submetidos à laringectomia supracricoide modificada entre agosto de 2010 e novembro de 2011. A avaliação endoscópica da deglutição por fibra ótica, os escores da versão curta do Voice Handicap Index e do MD Anderson Dysphagia Inventory, o tempo de alimentação oral e a decanulação dos pacientes foram comparados após a cirurgia em cada grupo. Resultados: A média do tempo máximo de fonação foi de 8,68 ± 4,21 segundos no Grupo A e 15,24 ± 6,16 segundos no Grupo B (p > 0,05). A razão S/Z (seg/seg) foi de 1,23 ± 0,35 no Grupo A e 1,08 ± 0,26 no Grupo B (p > 0,05); as médias do Voice Handicap Index foram 9,86 ± 4,77 no Grupo A e 12,42 ± 12,54 no Grupo B (p > 0,05); as médias da avaliação endoscópica da deglutição por fibra ótica foram calculadas como 12,73 ± 3,08 no Grupo A e 13,64 ± 1,49 no Grupo B (p > 0,05). Na avaliação da deglutição pelo MD Anderson Dysphagia Inventory, os escores emocional, físico e funcional foram 29,21 ± 4,11, 32,21 ± 6,85 e 20,14 ± 2,17 no Grupo B e 29,20 ± 2,54, 32,4 ± 4,79 e 19 ± 1,92 no Grupo A, respectivamente. Conclusão: Embora não haja diferença estatística nas comparações de resultados funcionais, se as regras forem respeitadas na seleção pré-operatória do paciente, a laringectomia supracricoide parcial modificada pode ser aplicada com segurança e ganhos significativos podem ser alcançados em termos de resultados funcionais.

Capacidade funcional em idosos e idosos mais velhos após alta da unidade de terapia intensiva. Coorte prospectiva / Functional ability in younger and older elderlies after discharge from the intensive care unit. A prospective cohort

RESUMO Objetivo: Comparar a capacidade funcional de indivíduos idosos (60 a 79 anos) com a dos idosos mais velhos (≥ 80 anos) nos primeiros 6 meses após a alta da unidade de terapia intensiva. Métodos: Coorte prospectiva multicêntrica, na qual foram coletados dados referentes à internação na unidade de terapia intensiva e aos desfechos após a alta hospitalar (no pós-alta imediato, após 3 meses e após 6 meses). A força muscular foi avaliada por meio do protocolo do Medical Research Council e da dinamometria (preensão palmar); a capacidade de execução das Atividades de Vida Diária e independência funcional pelo índice de Barthel e pelo nível habitual de atividade física (International Physical Activity Questionnaire); e a qualidade de vida pelo 12-Item Short-Form Health Survey Versão 2. Resultados: Dentre os 253 pacientes incluídos, 167 eram idosos entre 61 a 79 anos, e 86 eram idosos mais velhos. Os idosos mais velhos, no sexto mês de avaliação, apresentaram maior necessidade de cuidador (69,0% versus 49,5%; p = 0,002). A funcionalidade prévia à unidade de terapia intensiva e no terceiro mês após alta foi menor nos idosos mais velhos em comparação aos mais jovens (Barthel anterior à unidade de terapia intensiva: 73,0 ± 30,0 versus 86,5 ± 22,6; p < 0,001; Barthel no terceiro mês: 63,5 ± 34,0 versus 71,5 ± 35,5; p = 0,03), assim como o nível habitual de atividade física (International Physical Activity Questionnaire no terceiro mês: ativo/muito ativo 3,4% versus 18,3%; nenhuma atividade física 64,4% versus 39,7%; p < 0,001; e International Physical Activity Questionnaire no sexto mês: ativo/muito ativo 5,8% versus 20,8%; nenhuma atividade física 69,2% versus 43,4%; p = 0,005). Os idosos mais velhos apresentaram menor força muscular ao serem avaliados pela preensão palmar no membro dominante (14,5 ± 7,7 versus 19,9 ± 9,6; p = 0,008) e do não dominante (13,1 ± 6,7 versus 17,5 ± 9,1; p = 0,02). Não houve diferença na perda da funcionalidade e na qualidade de vida referida, entre os grupos etários. Conclusão: Mesmo com grande perda funcional após a alta da unidade de terapia intensiva em ambos os grupos etários, não houve diferença na magnitude da perda da funcionalidade de indivíduos idosos (60 a 79 anos) quando comparados aos idosos mais velhos (≥ 80 anos) nos primeiros 6 meses após a alta da unidade de terapia intensiva.

ABSTRACT Objective: To compare the functional capacity of younger elderly individuals (60 to 79 years old) with that of older elderly individuals (≥ 80 years old) during the first 6 months after discharge from the intensive care unit. Methods: A multicenter prospective cohort study was conducted, in which data on intensive care unit admission and outcomes after hospital discharge (immediate post-discharge, after 3 months and after 6 months) were collected. Muscle strength was evaluated through the protocol of the Medical Research Council and dynamometry (handgrip); the ability to perform activities of daily life and functional independence were assessed by the Barthel index and the usual level of physical activity (International Physical Activity Questionnaire); and quality of life was assessed by the 12-Item Short-Form Health Survey Version 2. Results: Among the 253 patients included, 167 were younger elderly (between 61 and 79 years old), and 86 were older elderly (≥ 80 years old). During the sixth month of evaluation, the older elderlies presented a higher need for a caregiver (69.0% versus 49, 5%, p = 0.002). Functional capacity prior to intensive care unit admission and in the third month after discharge was lower in older elderlies than in younger ones (Barthel prior to the intensive care unit: 73.0 ± 30.0 versus 86.5 ± 22.6; p <0.001, Barthel in the third month: 63.5 ± 34.0 versus 71.5 ± 35.5, p = 0.03), as was the usual level of physical activity (International Physical Activity Questionnaire in the third month: active/very active 3.4% versus 18.3%, no physical activity 64.4% versus 39.7%, p < 0.001, and International Physical Activity Questionnaire in the sixth month: active/very active 5.8% versus 20.8%, no physical activity 69.2% versus 43.4%, p = 0.005). Older elderlies had lower muscle strength when assessed according to handgrip in both the dominant (14.5 ± 7.7 versus 19.9 ± 9.6, p = 0.008) and non-dominant limb (13.1 ± 6.7 versus 17.5 ± 9.1, p = 0.02). There were no differences in functional capacity loss or reported quality of life between the age groups. Conclusion: Although there were great functional capacity losses after discharge from the intensive care unit in both age groups, there was no difference in the magnitude of functional capacity loss between younger (60 to 79 years) and older elderly individuals (≥ 80 years old) during the first 6 months after discharge from the intensive care unit.

Negative emotions affect postoperative scores for evaluating functional knee recovery and quality of life after total knee replacement

This study aimed to determine whether psychological factors affect health-related quality of life (HRQL) and recovery of knee function in total knee replacement (TKR) patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression, and KSS scores in TKR patients were significantly better compared with those preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were significantly improved compared with preoperative scores (P<0.001). Preoperative Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS) scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967, respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI) scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991, respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI), and BAI scores were also negatively associated with the N score (B=-0.367, -0.107, -0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth month after surgery was negatively associated with TAI and N scores (B=-0.315 and -0.532, respectively, both P<0.05), but positively associated with the E score (B=0.215, P<0.05). The postoperative KSS joint score was positively associated with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the scores used for evaluating recovery of knee function and HRQL after 6 months are inversely associated with the presence of negative emotions.

Body mass index and comorbidity are associated with postoperative renal function after nephrectomy

ABSTRACTPurpose:To explore the association of body mass index (BMI) and comorbidity with renal function after nephrectomy.Materials and Methods:We retrospectively analyzed 263 patients submitted to partial or radical nephrectomy from 2000-2013. Variables assessed included BMI, Charlson Comorbidity Index (CCI), race, tobacco use, tumor histology, surgical approach, Fuhrman nuclear grade, and tumor (T) classification. Glomerular filtration rate (GFR) was estimated using the Cockroft-Gault equation, adjusted for gender. Logistic regression was performed and included all interaction terms.Results:Median follow-up was 19.6 months (IQR 5.2, 53.7). Median preoperative GFR was 86.2mL/min/1.73m2 and median postoperative GFR was 68.4mL/min/1.73m2. BMI (OR 1.07, 95%CI 1.02-1.11), CCI (OR 1.19, 95%CI 1.04-1.37), and radical nephrectomy (OR 3.09, 95%CI 1.51-6.33) were significantly associated with a decline in renal function of ≥25%.Conclusion:BMI and CCI are associated with postoperative decline in renal function after nephrectomy. Additionally, radical nephrectomy is significantly associated with decreasing renal function compared to partial nephrectomy. These findings highlight the importance of assessing patient comorbidity in the decision making process for patients presenting with a renal mass.

Brain stimulation used as biofeedback training for recovery of motor functions deteriorated by stroke / A estimulação cerebral em pacientes com acidente vascular cerebral está associada a melhoria no desempenho motor e a incremento de eficácia na função neuronal

According to World Health Organization, approximately 15 million people are affected by cerebrovascular accident in the world. We study the effect of brain stimulation plus an imaging procedure used as biofeedback training for recovery of motor functions impaired by CVA. Four individuals aged between 33 and 72 years were included in the study, of both genders, with hemiparesis on the left arm due to the CVA. They had their brain activity monitored by EEG. Functional tasks were evaluated according to an observational model proposed by the international classification of functioning and by runtime. The training was composed of 12 sessions of 30 minutes of stimulation by light and sound, as well as imaging procedures. Results revealed that improvements in the performance of the task, with regard to both the runtime and the functional quality of movements, are more related to the increase of effectiveness of neuronal function.

Segundo a Organização Mundial da Saúde, aproximadamente 15 milhões de pessoas no mundo sofrem acidente vascular cerebral (AVC). Estudaram-se os efeitos da estimulação cerebral associada à imagética, como treinamento de biofeedback, para a recuperação das funções motoras deterioradas pelo AVC. Foram incluidos 4 indivíduos com idade entre 33 e 72 anos, de ambos os gêneros, e com hemiparesia no braço esquerdo devido ao AVC. Esses pacientes tiveram a atividade cerebral monitorada por EEG. A tarefa funcional foi avaliada de acordo com o modelo de observação proposto pela Classificação Internacional de Funcionalidade e pelo tempo de execução. O treinamento consistiu de 12 sessões de 30 minutos de estimulação por luz e som associado à imagética. Os resultados revelaram melhoria no desempenho da tarefa, tanto em relação ao tempo de execução quanto à qualidade funcional do movimento, e que está mais relacionada com o incremento de eficácia da função neuronal.

Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication / Estudo das alterações funcionais cardiorrespiratórias após a fundoplicatura laparoscópica à Nissen

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication. METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 ± 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods. RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 ± 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2. CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.

OBJETIVO: Analisar o comportamento da função cardiopulmonar no pós-operatório de fundoplicatura Nissen laparoscópica. MÉTODOS: Trinta e dois pacientes, 13 homens (41%) e 19 mulheres (59%) foram avaliados. A idade variou de 25 to 67 anos, com media de 44.4 ± 10.9. Os volumes pulmonares, as pressões respiratórias e testes de exercício foram realizados no período pré-operatório (PRE) e no primeiro (PO1), segundo (PO2), quinto (PO5) e trigésimo (PO30) períodos pós-operatórios. RESULTADOS: Trinta e dois pacientes foram avaliados, dos quais 59% eram do sexo feminino. A média de idade foi de 44,4 ± 10,9 anos. Os volumes pulmonares apresentaram diminuição significativa no PO1 e PO2 e foram semelhantes aos valores PRE no PO5. As pressões respiratórias estiveram alteradas apenas no PO1. A distância percorrida no teste da caminhada de 6 minutos apresentou redução significativa até o PO2, e o tempo de subida no teste de escada aumentou significativamente no PO2. CONCLUSÃO: Pacientes submetidos à FLN apresentaram diminuição da função cardiorrespiratória no início do período pós-operatório, no entanto, elas rapidamente regressaram às condições pré-operatórias.

Revisiting stapled and handsewn loop ileostomy closures: a large retrospective series

OBJECTIVE: To compare the surgical outcomes of stapled and handsewn closures in loop ileostomies. METHODS: The data of 225 patients requiring loop ileostomies from 2002 to 2007 were retrospectively evaluated. The patients underwent partial small-bowel resections and either handsewn or stapled anastomoses for the ileostomy closures. They were followed up postoperatively with routine surgical examinations. RESULTS: The study group consisted of 124 men and 101 women with a mean age of 49.12 years. The ileostomy closure was performed with handsewn in 129 patients and with stapled in 96 patients. The mean time to the first postoperative flatus was 2.426 days in the handsewn group and 2.052 days in the stapled group (p <0.05). The mean time to the first postoperative defecation was 3.202 days in the handsewn group and 2.667 days in the stapled group (p <0.05). The mean duration of patient hospital stay was 8.581 days for the handsewn group and 6.063 days for the stapled group (p <0.05). CONCLUSIONS: Patients who underwent ileostomy closure with stapled recovered faster in the postoperative period and required shorter hospital stays than those whose closures were performed with handsewn. In our opinion, stapled should be considered the gold standard for loop ileostomy closures.

Perfil epidemiológico dos pacientes de fisioterapia domiciliar no Rio de Janeiro / Epidemiololgical profile of pacients in home physical therapy in Rio de Janeiro

O presente estudo investigou o perfil epidemiológico dos pacientes assistidos no Centro de Fisioterapia Domiciliar, no Rio de Janeiro. A amostra estudada foi composta por todos os pacientes atendidos no período de 1 de janeiro de 1999 a 1 de janeiro de 2009, totalizando 1.203 indivíduos de ambos os sexos. De acordo com a metodologia adotada, a estatística descritiva foi utilizada para atingir os objetivos do estudo. Os dados coletados nos prontuários dos sujeitos do estudo foram organizados nos seguintes itens: faixa de idade, sexo e bairros (área de moradia dos pacientes). Com relação às doenças crônicas, foram analisados: os diferentes tipos de doenças, o tempo da patologia ao iniciar o tratamento e o nível de dependência. Com relação ao tratamento domiciliar de fisioterapia, foram analisados: o tipo de tratamento aplicado, o objetivo do tratamento, o tempo de permanência no tratamento e o nível de melhora obtido pelos pacientes. A análise comparativa utilizou o teste Qui-quadrado de Pearson e o linear, para as tendências estudadas. Todos os cálculos foram efetuados usando o software estatístico SPSS 16.0. Os resultados mostraram que o perfil epidemiológico do paciente atendido no Centro de Fisioterapia Domiciliar, no Rio de Janeiro é: idoso, com idade média de 75,8 anos, do sexo feminino, com sequela de AVC, acometido até um ano atrás (do início do tratamento), está restrito ao leito, com dependência de terceiros para deambular. O perfil do tratamento de fisioterapia domiciliar utilizado é do tipo motor com o objetivo de treino de marcha e equilíbrio; o tempo de permanência no tratamento é em média de 5,8 meses, com o resultado de boa melhora, que corresponde à recuperação da metade ou mais dos objetivos propostos na avaliação inicial. Confirmou-se que existe associação da idade com o "nível de dependência" dos pacientes, e que quanto maior a idade, maior a frequência encontrada na "restrição ao leito - total". Concluiu-se que a fisioterapia domiciliar...

This study investigated the epidemiological profile of patients attended at the Home-Based Physiotherapy Center in Rio de Janeiro. The study sample was made up of all the patients attended between January 1, 1999, and January 1, 2009, totaling 1.203 individuals of both sexes. In accordance with the methodology adopted, descriptive statistics were used to reach the study objectives. The data collected from the study subjects' medical files were organized into the following categories: age group, sex and district (area where the patients lived). The following were analyzed in relation to chronic diseases: different types of chronic disease, duration of the pathological condition at the start of treatment and level of dependence. Regarding the home-based physiotherapy, the following were analyzed: type of treatment applied, treatment objective, duration of the treatment and degree of improvement attained by the patients. The comparative analysis used the Pearson chi-square test and the linear test on the study trends. All the calculations were made using the SPSS 16.0 statistical software. The results showed that the epidemiological profile of the patients attended at the Home-Based Physiotherapy Center in Rio de Janeiro was as follows: elderly, with a mean age of 75.8 years; female; presenting sequelae from a stroke that occurred up to one year before the start of treatment; bedridden; and dependent on third parties to walk around. The home-based physiotherapy treatment used had a profile of motor type, with the aim of gait and balance training. The mean duration of the treatment was 5.8 months, resulting in a good improvement that corresponded to achievement of half or more of the objectives proposed at the initial assessment. It was confirmed that there was an association between age and the patients' "level of dependence", and that the greater their age was, the more often a "totally bidridden" condition was found. It was concluded that the home-based...

Importância da área de fibrose na evolução em médio prazo de pacientes submetidos à reconstrução ventricular / Importance of the area of fibrosis at midterm evolution of patients submitted to ventricular reconstruction / Importancia del área de fibrosis en la evolución a mediano plazo de pacientes sometidos a reconstrucción ventricular

Fundamento: Embora se reconheça que a cirurgia de reconstrução ventricular (CRV) promova remodelamento reverso, são necessários novos estudos para definir a influência da área de fibrose do ventrículo esquerdo (VE). Objetivo: Avaliar se a extensão da área de fibrose do VE é importante na recuperação funcional ventricular após CRV e correlacionar com fatores clínicos. Método: Análise prospectiva de 82 pacientes com disfunção ventricular submetidos à CRV. Analisou-se a importância das características clínicas e foram avaliadas as quantidades de fibrose, mensuradas por ressonância magnética em pequena, média e grande. Resultados: Todos os pacientes foram acompanhados por 36 meses, com mortalidade de 6 por cento. A quantidade de fibrose média foi de 25,8 por cento ± 13,6 por cento. Houve melhora da fração de ejeção do VE (FEVE), de 36,9 por cento ± 6,8 por cento para 48,2 por cento ± 8,2 por cento (p < 0,001). Houve relação inversa entre a quantidade de fibrose o incremento da FEVE (r = -0,83, p < 0,0001). Houve diminuição do volume sistólico final do VE de 43,3 ± 8,2ml/m² (p < 0,001). Houve melhora dos sintomas de insuficiência cardíaca, exceto nos pacientes com grande área de fibrose (p = 0,45). Os preditores independentes para eventos foram: área fibrótica (p = 0,01), idade (p = 0,01), volume sistólico final do VE (p = 0,03) e fração de ejeção (p = 0,02). O seguimento livre de evento foi diferente em relação à área de fibrose (p < 0,01). Conclusão: Em pacientes com disfunção ventricular, a extensão da área fibrótica foi um preditor independente da recuperação funcional do VE após CRV. A combinação de RMC e parâmetros clínicos podem auxiliar na indicação para CRV.

Background: Although it is acknowledged that the ventricular reconstruction surgery (VRS) can promote reverse remodeling, new studies are necessary to define the influence of the left ventricular (LV) area of fibrosis. Objective: To evaluate whether the extension of the area of fibrosis of the LV is important in the LV functional recovery after the surgery and correlate it with clinical factors. Methods: Prospective analysis of 82 patients with ventricular dysfunction submitted to VRS. We analyzed the importance of the clinical characteristics and the amount of fibrosis was assessed, measured by cardiac magnetic resonance (CMR) as small, medium and large. Results: All patients were followed for 36 months, with a mortality of 6 percent. The amount of medium fibrosis was 25.8 percent ± 13.6 percent. There was improvement in the left ventricular ejection fraction (LVEF), from 36.9 percent ± 6.8 percent to 48.2 percent ± 8.2 percent (p < 0.001). There was an inverse association between the amount of fibrosis and the increase in LVEF (r = -0.83, p < 0.0001). There was a decrease in the LV end-systolic volume of 43.3 ± 8.2ml/m² (p < 0.001). There was an improvement in heart failure symptoms, except in patients with large areas of fibrosis (p = 0.45). The independent predictors for events were: fibrotic area (p = 0.01), age (p = 0.01), LV end-systolic volume (p = 0.03) and LVEF (p = 0.02). The event-free follow-up was different in relation to the area of fibrosis (p < 0.01). Conclusion: In patients with ventricular dysfunction, the extension of the area of fibrosis was an independent predictor of the LV functional recovery after the VRS. The combination of cardiac MRI and clinical parameters can help in the indication for VRS.

Fundamento: Si bien se reconoce que la cirugía de reconstrucción ventricular (CRV) promueve remodelación reversa, son necesarios nuevos estudios para definir la influencia del área de fibrosis del ventrículo izquierdo (VE). Objetivo: Evaluar si la extensión del área de fibrosis del VI es importante en la recuperación funcional ventricular tras la CRV y correlacionarlo con factores clínicos. Método: Análisis prospectivo de 82 pacientes con disfunción ventricular sometidos a CRV. Se analizó la importancia de las características clínicas y se evaluaron las áreas de fibrosis, medidas por resonancia magnética y ponderadas como pequeña, mediana y grande. Resultados: Se realizó un seguimiento de 36 meses a todos los pacientes, con mortalidad del 6 por ciento. La cantidad de fibrosis promedio fue del 25,8 por ciento ± 13,6 por ciento. Existió una mejora de la fracción de eyección del VI (FEVI), del 36,9 por ciento ± 6,8 por ciento al 48,2 por ciento ± 8,2 por ciento (p < 0,001). Existió relación inversa entre la cantidad de fibrosis y el incremento de la FEVI (r = -0,83, p < 0,0001). Hubo una disminución del volumen de fin de sístole del VI de 43,3 ± 8,2ml/m² (p < 0,001). Se produjo una mejoría en los síntomas de insuficiencia cardiaca, excepto en los pacientes con gran área de fibrosis (p = 0,45). Los predictores independientes para eventos fueron: área de fibrosis (p = 0,01), edad (p = 0,01), volumen de fin de sístole del VI (p = 0,03) y fracción de eyección (p = 0,02). El seguimiento libre de eventos fue diferente en relación con el área de fibrosis (p < 0,01). Conclusión: En pacientes con disfunción ventricular, la extensión del área de fibrosis fue un predictor independiente de la recuperación funcional del VI luego de la CRV. La combinación de RMC y parámetros clínicos puede auxiliar en la indicación de CRV.

Isokinetic dynamometry in elderly women undergoing total knee arthroplasty: a comparative study

OBJETIVO: O presente estudo avaliou a dinamometria isocinética na determinação qualitativa da evolução da artroplastia total do joelho. CASUÍSTICA E MÉTODO: Vinte pacientes com média de 71, 35 anos, submetidas a artroplastia de joelho e 25 controles com média de 71,36 anos. Foi utilizada avaliação isocinética computadorizada para os músculos flexores e extensores dos joelhos num dinamômetro marca CYBEX® 6000. RESULTADOS: A análise estatística dos valores da relação entre o trabalho total flexor e extensor não demonstrou diferenças significativas entre o lado operado das pacientes e o lado não dominante das voluntárias. A relação flexão/extensão do torque máximo demonstrou uma diferença significativa entre o lado operado das pacientes e o lado não-dominante das voluntárias. CONCLUSÃO: Por detecção de deficiências do equilíbrio dos músculos flexores e extensores (equilíbrio este necessário para uma marcha uniforme), poderão ser enfatizados exercícios de reabilitação específicos conforme a necessidade de cada paciente operada.

Estudo da função ventricular na técnica de plicatura da parede livre do ventrículo esquerdo em cães / Left ventricular function after plication of the left ventricular free wall in dogs

OBJETIVO: Avaliar os efeitos da técnica na função ventricular esquerda em cães hígidos e com cardiomiopatia dilatada induzida pela doxorrubicina. MÉTODO: De 13 cães, oito receberam doxorrubicina até que a fração de encurtamento (FE) fosse menor que 20 por cento. Destes, quatro animais e os cinco não induzidos foram submetidos à plicatura da parede livre do ventrículo esquerdo (PPLVE). Os demais cães não foram operados. Foram avaliados débito cardíaco (DC), pressão arterial, exame físico, eletrocardiografia, sistema "Holter" e ecocardiografia, por 180 dias. RESULTADOS: Houve redução do volume ventricular esquerdo. Os cães induzidos melhoraram após a operação e a fração de ejeção (FEj) retornou aos valores normais para a espécie. O DC e a FE aumentaram após a operação. Um cão foi a óbito. Nos cães não operados, a FE diminuiu e foram a óbito em torno de 40 dias após a indução; nos cães não induzidos, esta não se alterou. Houve extra-sístoles ventriculares, que se resolveram espontaneamente. CONCLUSÕES: A PPLVE sem circulação extracorpórea reduz o volume ventricular esquerdo e melhora a função cardíaca dos cães com cardiomiopatia dilatada induzida pela doxorrubicina, demonstrando baixa morbidade e mortalidade tardia.
