RESUMO

The purpose of this study was to examine the effect of heating on the physical properties of four types of premixed calcium silicate-based root canal sealers. Endoseal MTA, Well-Root ST, EndoSequence BC Sealer, EndoSequence BC Sealer HiFlow, and AH Plus (epoxy resin root canal sealer) were heated at 100°C for 1 min, and changes in setting time, flow, and film thickness were evaluated in accordance with ISO 6876:2012 standards. In addition, pH measurement and scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses of the set materials were performed. All root canal sealers heated at 100°C showed significant decreases in setting time and flow, particularly Endoseal MTA. In addition, the film thickness of Endoseal MTA increased significantly after heating at 100°C. The pH and SEM/EDS results were not affected by heating. Heating calcium silicate-based root canal sealers accelerated setting time, decreased flow, and increased film thickness. However, the degree of these changes varied among the products. The present findings indicate that heat-induced changes in the physical properties of calcium silicate-based root canal sealers could adversely affect the quality of warm vertical condensation technique.

RESUMO

Objective: The aim of the current study was to examine the relationship between the straight leg raising (SLR) repetition count and both the knee extension strength (KES) and walking independence. Methods: We enrolled 106 inpatients aged ≥20 years with collagen disease in a cross-sectional study. We measured the SLR repetition count, KES, and walking independence of each participant. The correlations between the SLR repetition count and KES/walking independence were then examined. Furthermore, patients were divided into three groups depending on their SLR repetition count (low, medium, or high), and the differences among the groups were analyzed. Results: A moderately significant correlation was found between the SLR repetition count and KES (right: r=0.46, P<0.01; left: r=0.55, P<0.01). Moreover, there was a strong correlation between the maximum SLR repetition count and walking independence (r=0.74, P<0.01). Differences in KES and walking independence were observed among the SLR repetition groups (P<0.01). KES and walking independence in the group with a low repetition count were 0.08±0.04 kgf/kg and 1 (1-4) point, whereas the values in the group with a medium repetition count were 0.25±0.08 kgf/kg and 5 (1-7) points and those in the group with a high repetition count were 0.40±0.13 kgf/kg and 7 (4-7) points. Conclusion: The SLR repetition count is related to KES and walking independence. SLR repetition counts can be used in the clinical setting for the assessment of lower limb strength and walking independence.

RESUMO

Objective: The objective of the current study was to identify simple outcome measures to predict walking independence in inpatients with medical diseases in acute care hospitals and to identify the cut-off values of the relevant measures. Methods: Two hundred inpatients aged 20 years or above who had a medical disease were enrolled in this cross-sectional study. The subjects' walking independence, physical characteristics, cognitive status, and blood test data were examined. Logistic regression analysis was performed, and cut-off values were calculated. Results: The identified outcome measures and their respective cut-off values were as follows: the straight leg raising (SLR) repetition count, 27; the one-leg standing time (OLST), 3.6 s; and the orientation score of the mini-mental state examination (MMSE), 9/10. Conclusions: Our study findings suggest that the SLR repetition count, OLST, and the MMSE orientation score are simple outcome measures related to walking independence in inpatients with medical diseases in acute care hospitals.

RESUMO

To investigate the morphology and evolutionary origin of muscles in vertebrate limbs, we conducted anatomical dissections, computed tomography and kinematic analyses on the pectoral fin of the African coelacanth, Latimeria chalumnae. We discovered nine antagonistic pairs of pronators and supinators that are anatomically and functionally distinct from the abductor and adductor superficiales and profundi. In particular, the first pronator and supinator pair represents mono- and biarticular muscles; a portion of the muscle fibers is attached to ridges on the humerus and is separated into two monoarticular muscles, whereas, as a biarticular muscle, the main body is inserted into the radius by crossing two joints from the shoulder girdle. This pair, consisting of a pronator and supinator, constitutes a muscle arrangement equivalent to two human antagonistic pairs of monoarticular muscles and one antagonistic pair of biarticular muscles in the stylopod between the shoulder and elbow joints. Our recent kinesiological and biomechanical engineering studies on human limbs have demonstrated that two antagonistic pairs of monoarticular muscles and one antagonistic pair of biarticular muscles in the stylopod (1) coordinately control output force and force direction at the wrist and ankle and (2) achieve a contact task to carry out weight-bearing motion and maintain stable posture. Therefore, along with dissections of the pectoral fins in two lungfish species, Neoceratodus forsteri and Protopterus aethiopicus, we discuss the functional and evolutionary implications for the fin-to-limb transition and subsequent evolution of tetrapods.

RESUMO

A previous study reported a 45% incidence of falling among allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients during hospitalisation. We investigated balance and physical function in allo-HSCT patients. Thirty patients (18 men and 12 women) who underwent allo-HSCT between February 2013 and September 2014 were included in this study. Patients were evaluated for up to 3 weeks before and 7 weeks after transplantation. Balance was evaluated using the Timed Up and Go test (TUG) and length of centre of pressure (CoP). Physical function was assessed using hand-grip strength, knee-extensor strength tests, and the 6 min walk test (6MWT). TUG and length of CoP were significantly increased following HSCT (P<0.01). Hand-grip strength, knee-extensor strength, and the 6MWT score decreased significantly after allo-HSCT (P<0.01). TUG and length of CoP were negatively correlated with hand grip and knee-extensor strength (P≤0.05). The allo-HSCT patients in this study had worsened dynamic and static movements of the CoP after transplantation as well as decline of physical function. Rehabilitation staff, nurses, and physicians should recognize the decreased balance function of patients who have undergone allo-HSCT.

RESUMO

PURPOSE: This study investigated the differences between allogeneic haematopoietic stem cell transplantation (allo-HSCT) patients receiving HSC from human leucocyte antigen (HLA)-haploidentical donors (HID) and other donors that included HLA-matched sibling, matched unrelated, and unrelated umbilical cord blood donors in the 6 weeks after HSCT with respect to quality of life (QOL), psychological status, and physical function. METHODS: The study included 126 patients (HID group, n = 100; other donor group, n = 26) who underwent allo-HSCT between July 2007 and December 2012. Patients were evaluated for health-related QOL using the Medical Outcome Study 36-item Short Form Health Survey. Psychological status was measured by Hospital Anxiety and Depression Scale. Physical function was assessed using tests for handgrip strength, knee extensor strength, and the 6-min walk test. RESULTS: After HSCT, the HID group showed significantly greater improvements in the general health subscale and Mental Component Summary (MCS) of QOL than the other donor group (P < 0.01). Multivariate analysis confirmed that complete remission and age were associated with changes in the general health subscale before and after HSCT (P < 0.05). With regard to physical function, the HID group showed significantly more decline than the other donor group with respect to handgrip strength and knee extensor muscle strength after HSCT (P < 0.05). Total corticosteroid dose was associated with decreased handgrip strength before and after HSCT (P < 0.05). CONCLUSIONS: The donor type affects QOL, psychological status, and physical function in allo-HSCT recipients; these findings may provide insights for customised rehabilitation strategies for HSCT recipients.

RESUMO

A 39-year-old man developed fulminant myocarditis and was transferred on mechanical ventilation and a ventricular-assist device to our hospital. On Hospital Day 10, he was weaned from all medical engineering devices, and bedside rehabilitation was initiated. Although a multidisciplinary cardiac rehabilitation team had intervened since Hospital Day 3, he could not be encouraged to begin ambulation because of hypotension and tachycardia. Moreover, he complained of loss of self-confidence and anxiety regarding physical strength, and expansion of activities was difficult. Exercises reflecting his immediate desires and daily activities were used as activity goals, and we developed an individualized exercise program with stepwise increase in load to motivate him to perform rehabilitation. At the time of discharge, his cardiac function recovered to nearly normal levels; however, muscle strength and respiratory function had not recovered. While the intervention was continued at the cardiac rehabilitation outpatient unit, improvement was observed in physical health and mental health-related scale scores. The patient returned to work 4 months after onset of his myocarditis. Moreover, the cardiac rehabilitation team provided support to him for his long-term overseas assignment in the fifth year after myocarditis onset. Long-term comprehensive support by the cardiac rehabilitation team was feasible and useful. .

RESUMO

PURPOSE: The aim of this study was to investigate the relationship between corticosteroid dose and degree of physical function decrease in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients during the early stage of recovery. We further investigated the confounding factors affecting loss of physical function. METHODS: The study included 113 patients who underwent allo-HSCT between July 2007 and April 2012 at Hyogo College of Medicine Hospital in Japan. Physical function was assessed using tests for hand-grip strength, knee-extensor strength, and the 6-min walk test (6MWT). Fatigue was measured using the Piper Fatigue Scale. Total corticosteroid dose, frequency of physical therapy, body weight, and nutritional status were also collected from medical records. RESULTS: Total corticosteroid dose was correlated with decrease of hand-grip and knee-extensors strength (P < 0.01) but was not correlated with 6MWT performance. Results of multivariate analysis confirmed that low physical function was associated not only with high corticosteroid dose but also with low frequency of physical therapy, increase in fatigue, and body weight loss (P < 0.05). Also, hemoglobin levels were associated with 6MWT (P < 0.05). CONCLUSIONS: This study showed the relationship between corticosteroid dose and declines in physical function and also showed other clinical factors affecting loss of physical function among allo-HSCT patients. Our results indicate that the effectiveness of rehabilitation may be influenced by corticosteroid treatment.

RESUMO

OBJECTIVE: The aim of this study was to examine gender differences in quality of life (QOL), physical function and psychological status before and in the early phase after allogeneic haematopoietic stem cell transplantation (allo-HSCT). METHODS: One hundred patients (66 men, 34 women) who underwent allo-HSCT between July 2007 and June 2011 at Hyogo College of Medicine Hospital were included in this study. Patients were evaluated for health-related QOL using the Medical Outcome Study 36-item Short Form Health Survey; exercise capacity was measured with the 6-min walk test, hand grip strength and knee extensor strength. Fatigue and psychological status were measured by the Piper Fatigue Scale and Hospital Anxiety and Depression Scale, respectively. RESULTS: Women had significantly lower scores for physical function and general health on health-related QOL tests compared with men (p < 0.01). No difference between genders was found in decline of physical function. In women, exercise capacity was strongly associated with QOL (p < 0.01). In men, depression and anxiety were closely related to QOL (p < 0.01). CONCLUSIONS: Gender-appropriate rehabilitation in allo-HSCT patients is important. Women may need more endurance exercises and training for activities of daily life. Men may need rehabilitation including a psychological approach.
