RESUMO
OBJECTIVE: To examine the physical function and respiratory muscle strength of patients - who recovered from critical COVID-19 - after intensive care unit discharge to the ward on Days one (D1) and seven (D7), and to investigate variables associated with functional impairment. METHODS: This was a prospective cohort study of adult patients with COVID-19 who needed invasive mechanical ventilation, non-invasive ventilation or high-flow nasal cannula and were discharged from the intensive care unit to the ward. Participants were submitted to Medical Research Council sum-score, handgrip strength, maximal inspiratory pressure, maximal expiratory pressure, and short physical performance battery tests. Participants were grouped into two groups according to their need for invasive ventilation: the Invasive Mechanical Ventilation Group (IMV Group) and the Non-Invasive Mechanical Ventilation Group (Non-IMV Group). RESULTS: Patients in the IMV Group (n = 31) were younger and had higher Sequential Organ Failure Assessment scores than those in the Non-IMV Group (n = 33). The short physical performance battery scores (range 0 - 12) on D1 and D7 were 6.1 ± 4.3 and 7.3 ± 3.8, respectively for the Non-Invasive Mechanical Ventilation Group, and 1.3 ± 2.5 and 2.6 ± 3.7, respectively for the IMV Group. The prevalence of intensive care unit-acquired weakness on D7 was 13% for the Non-IMV Group and 72% for the IMV Group. The maximal inspiratory pressure, maximal expiratory pressure, and handgrip strength increased on D7 in both groups, but the maximal expiratory pressure and handgrip strength were still weak. Only maximal inspiratory pressure was recovered (i.e., > 80% of the predicted value) in the Non-IMV Group. Female sex, and the need and duration of invasive mechanical were independently and negatively associated with the short physical performance battery score and handgrip strength. CONCLUSION: Patients who recovered from critical COVID-19 and who received invasive mechanical ventilation presented greater disability than those who were not invasively ventilated. However, they both showed marginal functional improvement during early recovery, regardless of the need for invasive mechanical ventilation. This might highlight the severity of disability caused by SARS-CoV-2.

Epiphrenic diverticulum is a rare condition associated with esophageal motor disorder, and it is often asymptomatic, with a well-established surgical indication. The present study aims to report a case of a giant epiphrenic diverticulum in a 68-year-old male patient who, due to the symptoms, opted for surgical treatment using the daVinci® system. Robotic surgery consisting of esophageal diverticulectomy with cardiomyotomy was performed. The patient had an excellent recovery with an abbreviated hospitalization, return to food, and satisfactory routine activity.

RESUMO Objetivo: Examinar a função física e a força muscular respiratória de pacientes que se recuperaram da COVID-19 grave após a alta da unidade de terapia intensiva para a enfermaria nos Dias 1 e 7 e investigar as variáveis associadas ao comprometimento funcional. Métodos: Trata-se de estudo de coorte prospectivo de pacientes adultos com COVID-19 que necessitaram de ventilação mecânica invasiva, ventilação mecânica não invasiva ou cânula nasal de alto fluxo e tiveram alta da unidade de terapia intensiva para a enfermaria. Os participantes foram submetidos aos testes Medical Research Council sum-score, força de preensão manual, pressão inspiratória máxima, pressão expiratória máxima e short physical performance battery. Os participantes foram agrupados em dois grupos conforme a necessidade de ventilação mecânica invasiva: o Grupo Ventilação Mecânica Invasiva (Grupo VMI) e o Grupo Não Ventilação Mecânica Invasiva (Grupo Não VMI). Resultados: Os pacientes do Grupo VMI (n = 31) eram mais jovens e tinham pontuações do Sequential Organ Failure Assessment mais altas do que os do Grupo VMI (n = 33). As pontuações do short physical performance battery (intervalo de zero a 12) nos Dias 1 e 7 foram 6,1 ± 4,3 e 7,3 ± 3,8, respectivamente para o Grupo Não VMI, e 1,3 ± 2,5 e 2,6 ± 3,7, respectivamente para o Grupo VMI. A prevalência de fraqueza adquirida na unidade de terapia intensiva no Dia 7 foi de 13% para o Grupo Não VMI e de 72% para o Grupo VMI. A pressão inspiratória máxima, a pressão expiratória máxima e a força de preensão manual aumentaram no Dia 7 em ambos os grupos, porém a pressão expiratória máxima e a força de preensão manual ainda eram fracas. Apenas a pressão inspiratória máxima foi recuperada (ou seja, > 80% do valor previsto) no Grupo Não VMI. As variáveis sexo feminino, e necessidade e duração da ventilação mecânica invasiva foram associadas de forma independente e negativa à pontuação do short physical performance battery e à força de preensão manual. Conclusão: Os pacientes que se recuperaram da COVID-19 grave e receberam ventilação mecânica invasiva apresentaram maior incapacidade do que aqueles que não foram ventilados invasivamente. No entanto, os dois grupos de pacientes apresentaram melhora funcional marginal durante a fase inicial de recuperação, independentemente da necessidade de ventilação mecânica invasiva. Esse resultado pode evidenciar a gravidade da incapacidade causada pelo SARS-CoV-2.
RESUMO
Abstract Background There is no consensus among tools for assessing frailty. Objective To evaluate the prevalence of frailty according to different tools in patients referred for elective valve cardiac surgery. Methods This is a cross-sectional study. All patients were ≥ 18 years of age, clinically stable. The following patients were excluded: those unable to perform the tests because of physical, cognitive, or neurological limitations; those requiring non elective/emergency procedures or hemodynamic instability. During the preoperative cardiology visit, frailty was assessed by the Short Physical Performance Battery (SPPB), the Frailty Deficit Index (FDI), handgrip strength, and gait speed 3m. For the entire analysis, the statistical significance was set at 5%. Results Our cohort consisted of 258 subjects. From the total cohort, 201 were ≤ 70 years of age (77.9%), the predominant etiology according to rheumatic disease (50.7% vs 8.8%; p=0.000) with double mitral lesion (24.9% vs 0%; p=0.000). Frailty was present in 32.9% according SPPB, 29.1% with reduced muscular strength. and 8.9% with FDI. Handgrip strength was weaker in elderly patients (26.7 vs 23.6; p=0.051) and gait speed was lower in the younger group, in which 36% were considered frail (36% vs 14%; p=0.002). Variables associated with frailty were age ≥ 70 years, female gender, aortic stenosis, and regurgitation. Conclusion Frailty in adult patients who will have elective heart valve surgery is present even in the younger groups, although the older group with comorbidities are more frail. Frailty was more clearly shown by the SPPB than by the FDI and handgrip tests.

ABSTRACT This study aimed to determine the effectiveness of LLLT in decreasing the lung inflammatory process in septic rats. A total of 32 male Wistar rats were divided into four groups (n=8): control group (CG), sepsis 24h (S24), sepsis and LLLT with 30 J/cm² (S24L30); sepsis and LLLT with 65 J/cm² (S24L65). The irradiation was performed immediately after surgery in the anterior region of the trachea and ventral regions of the chest, bilaterally, just below the ribs. Histological analysis of lung tissue was performed and the number of inflammatory cells was quantified. The S24 group showed an increase of inflammatory cells compared to the CG (p <0.01); S24L30 increased the number of inflammatory cells, while S24L65 decreased this number compared to S24 (both p<0.05); S24L65 had a lower number of inflammatory cells compared to S24L30 (p<0.01). In conclusion, LLLT at a specific energy dose (30J / cm²) was capable of decreasing the number of inflammatory cells in acute lung tissue inflammation due to sepsis.
RESUMO O objetivo do estudo foi determinar a eficácia da LLLT na diminuição do processo inflamatório pulmonar em ratos sépticos. Foram utilizados 32 ratos machos Wistar divididos em quatro grupos (n=8): controle (CG); sepse 24h (S24); sepse e tratamento com LLLT 30 J/cm² (S24L30); sepse e tratamento com LLLT 65 J/cm² (S24L65). A irradiação foi realizada imediatamente após a cirurgia na região anterior de traqueia e nas regiões ventrais do tórax, bilateralmente, logo abaixo das costelas. Foi realizada análise histológica do tecido pulmonar e o número de células inflamatórias foi quantificado. O grupo S24 apresentou um aumento de células inflamatórias comparado ao CG (p <0,05); S24L30 aumentou o número de células inflamatórias, enquanto S24L65 diminuiu este numero em relação ao S24 (ambos p <0,05); S24L65 diminui o numero de células inflamatórias comparado ao S24L30 (p<0.01). Concluiu-se que LLLT em dose específica de energia (30J/cm²) foi capaz de diminuir o número de células inflamatórias no tecido pulmonar em fase aguda da sepse.
