Post-Acute Care for Traumatic Brain Injury Patients in Taiwan.

Background: Traumatic brain injury (TBI) can result in functional impairments. Many patients with TBI require post-acute care to improve their functional skills and allow for greater self-independence and a better quality of life. Taiwan's National Health Insurance proposed a nationwide post-acute care program in 2017 for patients with traumatic brain injury. The program's goal was to maximize patients' functional recovery and make it possible for them to return to their homes and communities. This study aimed to explore the effectiveness of such programs in Taiwan. Methods: This pilot study retrospectively evaluated a de-identified database that contained the scores of various assessments evaluated at admission and discharge. It used the data to determine the functional improvement of patients with traumatic brain injury after participating in post-acute care programs. Results: This study collected complete data from 27 patients. After an average of 45.11 days in the program, the patients showed significant improvement in the Barthel Activity Daily Living Index, the Lawton-Brody Instrumental Activity Daily Living Scale, the Mini Nutrition Assessment, the EuroQol Five Dimensions Questionnaire, the Berg Balance Scale, the Galveston Orientation and Amnesia Test, the Rancho Los Amigos Scale, the Concise Chinese Aphasia Test, and the Mini Mental State Examination. After discharge, 96% of the patients could return to their community. Conclusion: This pilot study concluded that the program significantly promoted functional recovery for patients and could help patients with traumatic brain injury return to their communities and reduce the risk of institutionalization. Thus, patients with the potential for functional recovery could receive post-acute care in regional or community hospitals immediately after being discharged from acute wards. In the future randomized controlled trials are needed to further confirm the clinical impact of this program.

Preliminary study on the application of bioimpedance analysis to measure the psoas major muscle in older adults.

For the assessment of sarcopenia or other geriatric frailty syndromes, psoas major area may be one of the primary indicators. Aim to develop and cross-validate the psoas cross-sectional area estimation equation of L3-L4 of the elderly over 60 years old by bioelectrical impedance analysis (BIA). Ninety-two older adults with normal mobility were enrolled (47 females, 45 males), and were randomly divided into a modeling group (MG, n = 62) and validation group (VG, n = 30). Computed tomography (CT) was used to measure the psoas major area at the' L3-L4 lumbar vertebrae height as a predictor. Estimated variables were height (h), whole body impedance (Zwhole), whole body impedance index (h2/Zwhole, WBI), age, gender (female = 0, male = 1), and body weight (weight) by standing BIA. Relevant variables were estimated using stepwise regression analysis. Model performance was confirmed by cross-validation. BIA estimation equation for PMM obtained from the MG was: (PMMBIA = 0.183 h2/Z- 0.223 age + 4.443 gender + 5.727, r2 = 0.702, n = 62, SEE = 2.432 cm2, p < 0.001). The correlation coefficient r obtained by incorporating the VG data into the PMM equation was 0.846, and the LOA ranged from -4.55 to 4.75 cm2. PMMBIA and PMMCT both correlate highly with MG or VG with small LOA. The fast and convenient standing BIA for measuring PMM may be a promising method that is worth developing.

The Effectiveness of Whole-Body Vibration and Heat Therapy on the Muscle Strength, Flexibility, and Balance Abilities of Elderly Groups.

Whole-body vibration (WBV) is a novel exercise training measure that promotes the muscle strength, flexibility, and balance abilities of elderly groups. The feasibility and applicability of 20-30 min (lowering a heat pack at 73 °C by wrapping it in multiple layers of towels to 40-43 °C before it touched the skin) thermotherapy are increasingly being demonstrated by applications and clinical trials. Studies show that it increases the flexibility of macules and ligament. However, no studies have examined the interactions between the pre-exercise and post-exercise application of heat therapy (duration a training course). Therefore, this study investigates the effects of WBV and heat therapy on the muscle strength, flexibility, and balance abilities of elderly groups. Eighty middle-age and elderly participants with no regular exercise habits were enrolled in this study. They were randomly assigned to a WBV group, a WBV plus heat therapy group, a heat therapy alone group, and a control group. The WBV groups underwent 5-min, fixed-amplitude (4 mm), thrice-weekly WBV training sessions for 3 consecutive months on a WBV training machine. Participants' balance was measured using the limits of stability (LOS) test on a balance system. The pretest and posttest knee extensor and flexor strength were tested using an isokinetic lower extremity dynamometer. Pretest and posttest flexibility changes were measured using the sit-and-reach test. Significantly larger pretest and posttest differences in flexibility and muscle strength were observed in the WBV and WBV plus heat therapy groups. The addition of heat therapy to WBV resulted in the largest flexibility improvements.

Assessment of Standing Multi-Frequency Bioimpedance Analyzer to Measure Body Composition of the Whole Body and Limbs in Elite Male Wrestlers.

We investigated differences in body composition measurements for the whole body and limb segments in elite male wrestlers between results of multi-frequency bioelectrical impedance analyses (MFBIA) and dual energy X-ray absorptiometry (DXA). Sixty-six elite male wrestlers from Taiwan were recruited. Wrestlers' body fat percentage (PBFWB), whole body fat-free mass (FFMWB), whole body lean soft tissue mass (LSTMWB), and fat-free mass of arms, legs and trunk (FMArms, FFMLegs, FFMTrunk) were measured by MFBIA and DXA, and analyzed using Pearson correlation coefficient and Bland-Altman plot. Correlations of FFMWB, LSTMWB, and PBFWB between devices were 0.958, 0.954, and 0.962, respectively. Limits of agreement (LOA) of Bland-Altman plot were -4.523 to 4.683 kg, -4.332 to 4.635 kg and -3.960 to 3.802%, respectively. Correlations of body composition parameters FFMArms, FFMLegs and FFMTurnk between devices in each limb segment were 0.237, 0.809, and 0.929, respectively; LOAs were -2.877 to 2.504 kg, -7.173 to -0.015 kg and -5.710 to 0.777 kg, respectively. Correlation and consistency between the devices are high for FFM, LSTM and PBF but relatively low for limb segment FFM. MFBIA may be an alternative device to DXA for measuring male wrestlers' total body composition but limb segment results should be used cautiously.

Bioimpedance analysis combined with sagittal abdominal diameter for abdominal subcutaneous fat measurement.

Abdominal subcutaneous fat tissue (ASFT) is an independent predictor of mortality. This prospective observational study aimed to establish a rapid, safe, and convenient estimation equation for abdominal subcutaneous fat area (SFA) using bioimpedance analysis (BIA) combined with sagittal abdominal diameter (SAD). A total of 520 adult subjects were recruited and were randomly divided into 2/3 (n = 346) and 1/3 (n = 174) to form a modeling group (MG) and a validation group (VG), respectively. Each subject's abdomen was scanned using computed tomography to obtain target variables (SFACT). Predictor variables for all subjects included bioimpedance index (h2/Z), anthropometric parameters height (h), weight (W), waist circumference (WC), hip circumference (HC), and SAD, along with age and sex (male =1, female = 0). SFA estimation equation SFABIA+SAD was established for the MG using stepwise multiple regression analysis. Cross-validation was performed using VG to evaluate the performance of the SFABIA+SAD estimation equation. Stepwise multiple regression analysis was applied from the MG, including SFABIA+SAD = 49.89 + 1.09 SAD-29.90 Sex + 4.71 W-3.63 h2/Z-1.50 h (r = 0.92, SEE = 28.10 cm2, n = 346, p < 0.001). Mean differences in SFABIA+SAD relative to SFACT were -1.21 ± 21.53, 2.85 ± 27.16, and -0.98 ± 36.6 cm2 at different levels of obesity (eutrophic, overweight, obese), respectively. This study did not have a large number of samples in different fields, so it did not have completely external validity. Application of BIA combined with SAD in anthropometric parameters achieves fast, accurate and convenient SAF measurement. Results of this study provide a simple, reliable, and practical measurement that can be widely used in epidemiological studies and in measuring individual SFA.

A multicenter study to compare the effectiveness of the inpatient post acute care program versus traditional rehabilitation for stroke survivors.

There is insufficient evidence to prove the effect of the Post-acute Care (PAC) program on post-stroke recovery. This study aimed to determine the effectiveness of the PAC versus traditional inpatient rehabilitation (non-PAC) for middle- and old-aged stroke survivors. This multicenter cohort study enrolled 334 stroke patients admitted for post-stroke rehabilitation. The outcome variables included the Barthel Index (BI), Functional Oral Intake Scale (FOIS), Mini Nutritional Assessment-Short Form (MNA-SF), EuroQoL-5D (EQ-5D), Lawton-Brody Instrumental Activities of Daily Living (ADL) Scale, and Mini-Mental State Examination (MMSE). The inverse-probability-of-treatment-weighting method was used to analyze the differences in outcomes between the PAC and non-PAC groups. The PAC group showed better improvements in BI, MNA-SF, EQ-5D, Instrumental ADL, and MMSE compared to the non-PAC group, with differences in effect sizes of 0.54 (95% confidence interval [CI] 0.38-0.71), 0.26 (95% CI 0.10-0.42), 0.50 (95% CI 0.33-0.66), 0.44 (95% CI 0.28-0.60) and 0.34 (95% CI 0.17-0.50), respectively. The PAC project showed more improvement in basic and instrumental ADL and status of swallowing, nutrition, and cognition than those of non-PAC, which had less length of stay restricted by the National Health Insurance. More studies are warranted to investigate the influence of hospital stay and duration from stroke onset on the PAC's effectiveness.

Return to preinjury sports after anterior cruciate ligament reconstruction is predicted by five independent factors.

PURPOSE: To determine factors that predict return to the same frequency and type of sports participation with similar activity demands as before injury. METHODS: Individuals 1 to 5 years after primary ACL reconstruction completed a comprehensive survey related to sports participation and activity before injury and after surgery. Patient characteristics, injury variables, and surgical variables were extracted from the medical record. Return to preinjury sports (RTPS) was defined as: "Returning to the same or more demanding type of sports participation, at the same or greater frequency with the same or better Marx Activity Score as before injury." Variables were compared between individuals that achieved comprehensive RTPS and those that did not with univariate and multivariate logistic regression models. RESULTS: Two-hundred and fifty-one patients (mean age 26.1 years, SD 9.9) completed the survey at an average of 3.4 years (SD 1.3) after ACL reconstruction. The overall rate of RTPS was 48.6%. Patients were more likely to RTPS if they were younger than 19 years old (OR = 4.07; 95%CI 2.21-7.50; p < 0.01) or if they were competitive athletes (OR = 2.07; 95%CI 1.24-3.46; p = 0.01). Patients were less likely to RTPS if surgery occurred more than 3 months after injury (OR = 0.31, 95%CI 0.17-0.58; p < 0.01), if there was a concomitant cartilage lesion (OR = 0.38; 95%CI 0.21-0.70; p < 0.01), and if cartilage surgery was performed (OR = 0.17; 95%CI 0.04-0.80; p = 0.02). CONCLUSION: Five variables best predicted RTPS including age at time of surgery. Only time from injury to surgery is a potentially modifiable factor to improve RTPS; however, the reasons for which patients delayed surgery may also contribute to them not returning to sports. Regardless, younger patients, those that partake in sports on a competitive level, those that undergo surgery sooner, or do not have a cartilage injury or require cartilage surgery are more likely to return to pre-injury sports participation. LEVEL OF EVIDENCE: III.

Is 20 Hz Whole-Body Vibration Training Better for Older Individuals than 40 Hz?

In recent years, whole-body vibration (WBV) training has been used as a training method in health promotion. This study attempted to use WBV at three different frequencies (20, 30, and 40 Hz) with subjects from different age groups to analyze the activation of the rectus femoris muscle. The subjects included 47 females and 51 males with an average age of 45.1 ± 15.2 years. Results indicated significant differences in subjects from different age groups at 20 Hz WBV. Muscle contraction was greater in the subjects who were older (F(4,93) = 82.448, p < 0.001). However, at 30 Hz WBV, the difference was not significant (F(4,93) = 2.373, p = 0.058). At 40 Hz WBV, muscle contraction was less in the older subjects than in the younger subjects (F(4,93) = 18.025, p < 0.001). The spectrum analysis also indicated that at 40 Hz there was less muscle activity during WBV in the older subjects than in the younger ones. Therefore, age was found to have a significant effect on muscle activation during WBV at different frequencies. If the training is offered to elderly subjects, their neuromuscular responses to 20 Hz WBV will be more suitable than to 40 Hz WBV.

Assessment of total and regional bone mineral density using bioelectrical impedance vector analysis in elderly population.

This study aimed to investigate the relationship between bone mineral density (BMD) and height-adjusted resistance (R/H), reactance (Xc/H) and phase angle (PhA). A total of 61 male and 64 female subjects aged over 60 years were recruited from middle Taiwan. The R and Xc were measured using Bodystat Quadscan 4000 at a frequency of 50 kHz. BMD at the whole body, L2-L4 spine, and dual femur neck (DFN), denoted as BMDTotal, BMDL2-L4, and BMDDFN, were calculated using a Hologic DXA scanner. The R-Xc graph was used to assess vector shift among different levels of BMD. BMD was positively correlated with Xc/H and negatively correlated with R/H (p < 0.001). The General Linear Model (GLM) regression results were as follows: BMDTotal = 1.473-0.002 R/H + 0.007 Xc/H, r = 0.684; BMDL2-L4 = 1.526-0.002 R/H + 0.012 Xc/H, r = 0.655; BMDDFN = 1.304-0.002 R/H + Xc/H, r = 0.680; p < 0.0001. Distribution of vector in the R-Xc graph was significantly different for different levels of BMDTotal, BMDL2-L4 and BMDDFN. R/H and Xc/H were correlated with BMD in the elderly. The linear combination of R/H and Xc/H can effectively predict the BMD of the whole body, spine and proximal femur, indicating that BIVA may be used in clinical and home-use monitoring tool for screening BMD in the elderly in the future.

Doppler-guided hemorrhoidal artery ligation with suture mucopexy compared with LigaSure™-assisted pile excision for the treatment of grade III hemorrhoids: a prospective randomized controlled trial.

BACKGROUND: Doppler-guided hemorrhoid artery ligation and stapled hemorrhoidopexy have been used in surgical practices to avoid post-hemorrhoidectomy pain. Our study compared Doppler-guided hemorrhoid artery ligation with suture mucopexy (DGHAL-SM) and ligature-assisted pile excision (LAP) for greater than three grades of internal hemorrhoids. METHODS: Eighty patients with greater than 3 grades of internal hemorrhoids were selected (age range: 20-28 years; average age: 23 years) between January and June 2015. The patients were randomly divided into group A (DGHAL-SM) and group B (LAP); each group had 40 patients. RESULTS: With respect to the postoperative cure rate and anal skin tags, group A was inferior to group B, but the postoperative pain assessment and satisfaction were better than group B (P<0.001). CONCLUSIONS: The DGHAL-SM cure rate was high; the postoperative pain was mild; 97.5% of the patients did not return to hospital because of pain. LAP has a higher cure rate than DGHAL-SM, but the postoperative pain and return rate within 6 h was as high as 65%, and the postoperative satisfaction assessment was lower than DGHAL-SM. Therefore, we recommend that DGHAL-SM for outpatient surgery in patients with greater than three grades of internal hemorrhoids.

Standing 8-Electrode Bioelectrical Impedance Analysis as an Alternative Method to Estimate Visceral Fat Area and Body Fat Mass in Athletes.

PURPOSE: To investigate the potential of standing 8-electrode bioelectrical impedance analysis (BIA) for assessing visceral fat area (VFA) and body fat mass (BFM) in athletes. MATERIALS AND METHODS: A total of 95 subjects (50 males and 45 females) were recruited. VFA and BFM measurements were obtained using three standing 8-electrode BIA devices, InBody230, InBody770, and IOI353. These acquired VFA and BFM were expressed as VFAIOI353, VFAInBody230, VFAInBody770 V, BFMIOI353, BFMInBody230, and BFMInBody770, respectively. As reference measurement, the VFA acquired from computer tomography (CT) was expressed as VFACT, and the BFM measured by dual-energy X-ray absorptiometry (DXA) was denoted as BFMDXA. RESULTS: The coefficient of determination (r2) in regression analysis between the measurements by VFAIOI353, VFAInBody230, VFAInBody770 and VFACT were 0.425, 0.492, and 0.473, respectively. Also, the limits of agreement (LOA) obtained from Bland-Altman analysis were -25.18 to 56.62, -29.74 to 62.44, and -32.96 to 71.93 cm2. For BFM, r2 in regression analysis between the measurements by BFMIOI353, BFMInBody230, BFMInBody770 and BMFDXA were 0.894, 0.950, and 0.955, respectively; LOA were -7.21 to 5.75, -4.70 to 4.05, and -5.48 to 3.05 kg, respectively. CONCLUSION: The results showed when assessing BFM, these instruments delivered comparable measurements, and the degree of agreement ranged from excellent to moderate compared with the reference method. However, when assessing VFA, the agreements were weak. Therefore, the application of standing 8-electrode BIA devices for assessing athletes' VFA still needs improvement.

Prediction and discrimination of skeletal muscle function by bioelectrical impedance vector analysis using a standing impedance analyzer in healthy Taiwanese adults.

BACKGROUND: Bioelectrical impedance vector analysis (BIVA) has been used for prediction of muscle performance. However, little is known about BIVA in Asian adults, and even less is known about using standing BIVA devices. Standing impedance analyzer allows quicker and more convenient way to gather data than conventional supine analyzer and is more suitable for clinical practice. This study aimed to investigate the relations between muscle function and BIVA parameters measured with a standing impedance analyzer in healthy Taiwanese adults. METHODS: A total of 406 healthy subjects (age 34.5 ± 17.3 years, body mass index 24.1 ± 4.1 kg/m2) were recruited for BIVA and handgrip strength (HGS) measurements. Impedance parameters, including resistance (R) and reactance (Xc), were measured and normalized to body size by dividing by height (H). The resulting phase angle (PhA) was calculated. HGS in the dominant, left, and right hands were referred to as HGSDH, HGSLH, and HGSRH, respectively. All subjects were divided into 5 grades according to HGS. RESULTS: Muscle strength in the dominant, right, and left arms was correlated with variables in the order of sex, weight, age, height, Xc/H, and R/H (all, p < 0.001). Using all 6 variables, the determination coefficients were 0.792, 0.782, and 0.745, respectively, whereas the standard errors of estimates were 56.89, 58.01, and 56.67 N for HGSDH, HGSLH, and HGSRH, respectively. HGS was positively correlated with PhA, and negatively correlated with Xc/H and R/H. CONCLUSIONS: BIVA parameters measured with a standing impedance analyzer and anthropometric variables can predict and discriminate muscle function with good performance in healthy Asian adults.

Popliteal Artery Entrapment Syndrome in a Young Baseball Pitcher: A Case Report.

BACKGROUND: Popliteal artery entrapment syndrome (PAES) is a rare disease in young adults and is thought to be under-diagnosed, and its main cause is the abnormal structure between the popliteal artery and gastrocnemius muscle. The patients experience symptoms after the blood vessels are compressed. Failure to diagnose and treat PAES can cause serious sequelae. CASE: A 19-year-old male baseball pitcher with PAES type 2 suffered from left calf muscle tension and foot numbness and was mis-diagnosed for nearly a year. Finally, the lesion was detected by ultrasonography and confirmed by magnetic resonance imaging. After surgical intervention, he quickly returned to sport. DISCUSSION/CONCLUSION: PAES has 6 types. Type 2 (25%) and type 3 (30%) are the most common. Patients with this syndrome suffer from aching pain, numbness, and cramping in the calf area when they exercise. It is necessary to include this disease in differential diagnosis to implement early diagnosis, and ultrasonography is a more cheap and simple method for early detection.

Comparison of Bioelectrical Impedance Analysis and Dual Energy X-ray Absorptiometry for Total and Segmental Bone Mineral Content with a Three-Compartment Model.

Modern bioelectrical impedance analysis (BIA) provides a wide range of body composition estimates such as fat mass (FM), lean body mass (LBM), and body water, using specific algorithms. Assuming that the fat free mass (FFM) and LBM can be accurately estimated by the 8-electrode BIA analyzer (BIA8MF; InBody230, Biospace), the bone mineral content (BMC) may be calculated by subtracting the LBM from the FFM estimates based on the three-compartment (3C) model. In this cross-sectional study, 239 healthy Taiwanese adults (106 male and 133 female) aged 20-45 years were recruited for BIA and dual-energy X-ray absorptiometry (DXA) measurements of the whole body and body segments, with DXA as the reference. The results showed a high correlation between BIA8MF and DXA in estimating total and segmental LBM, FM and percentage body fat (r = 0.909-0.986, 0.757-0.964, and 0.837-0.936, respectively). For BMC estimates, moderate to high correlations (r = 0.425-0.829) between the two methods were noted. The percentage errors and pure errors for BMC estimates between the methods ranged from 33.9% to 93.0% and from 0.159 kg to 0.969 kg, respectively. This study validated that BIA8MF can accurately assesses LBM, FM and body fat percentage (BF%). However, the estimation of segmental BMC based on the difference between FFM and LBM in body segments may not be reliable by BIA8MF.

Using a numerical method to precisely evaluate the alpha angle in a hip image.

The alpha angle is a parameter extensively used to assess for cam-type femoroacetabular impingement (FAI) in a 2D image of the hip. As this angle requires estimation of the axis of the femoral neck, the drawing of this axis often results in measurement errors due to subjective judgment, influencing inter-rater and intra-rater agreements. In the present study, sampling points were captured from the edges of a femoral neck and head in the 2D image, and the best curves of the two were fitted respectively by using the curve fitting method. The morphology of the femoral neck was outlined by two polynomials, and the femoral head was represented by an equation of a circle. By means of the proposed method, the results reveal that the inter-rater ICCs in X-ray and MRI were respectively 0.905 and 0.969, and the intra-rater ICCs in X-ray and MRI were respectively 0.892 and 0.840. The Bland-Altman plot shows that the values obtained by the proposed method and the conventional method were not consistent; nevertheless, the linear regression analysis indicated the two measurement results had a significant association (p < 0.001). This study provides a repeatable and agreed α angle measuring method, which contributes to identifying normal and abnormal femoral head-neck morphologies. The proposed numerical method would contribute to diagnose early FAI.

Different weight shift trainings can improve the balance performance of patients with a chronic stroke: A randomized controlled trial.

BACKGROUND: Improving balance ability, increasing walking ability, and reducing the occurrence of falls are important objectives in the rehabilitation of stroke patients. Do the posture balance training and the intervention of lateral wedge insoles to improve of balance function and increase walking ability in patients with a chronic stroke? METHODS: A randomized, controlled trial with concealed allocation, intention-to-treat analysis, and blinded assessors. Participants who had a chronic stroke (onset >6 months) were recruited from the rehabilitation and neurology departments of a hospital in central Taiwan. Subjects were divided into 3 groups: a visual biofeedback balance training group, a lateral wedge group, and a control group; apart from their usual rehabilitation program, and both experimental groups received a 6-week training session program. The primary outcome was the balance computerized adaptive test (balance CAT), and secondary outcome was timed up and go (TUG) test. All subjects were evaluated at the baseline, posttraining (6-week), 1st follow-up (10-week), and 2nd follow-up (18-week). RESULTS: A total of 56 subjects were participated in this study, including 38 males and 18 females. The mean age of the subjects was 59.1 years old, and the mean time was 43.7 months after the onset of the stroke. This study found the interaction in groups and measurement time points reached statistical significance of the balance CAT and TUG test (F = 5.740, P < .001; F = 2.926, P = .011; respectively). In addition, the performance of both the visual biofeedback training and lateral wedge group was superior to that of the control group. CONCLUSION: Six-week visual biofeedback training and intervention of 5° lateral wedge insoles can improve the balance ability of patients with a chronic stroke.

[Sharing Perspectives on Home Healthcare].

The baby boom after World War II, coupled with the rapid advances in medical technology and public health, has led to the current rapid aging in the world's population. Countries in Asia are experiencing a faster rate of aging than most other countries around the world. Taiwan is expected to advance from an aged society to a super-aged society in the next 7~10 years. Consequently, the demand for long-term care is increasing. The focus of healthcare has changed from acute to chronic, from disease-oriented to function-oriented and from cure to care. Families, once the cornerstone of care, have become overwhelmed by the effects of the declining birthrate and aging. Encountering the public demand for a balance between healthcare and quality of life has led to the increasing role of home-based care in the medical system. The elderly-care profession is diverse and growing. The trend of transdisciplinary team which integrating care professions, nursing professions, family medicine, geriatric medicine, rehabilitation medicine, telemedicine, and medical aids with the resource of social welfare enables home health care services to better provide well-rounded medical care. Before end of life, hospice home care services increase the likelihood of dying at home in accordance with the patient's preference, easing the symptoms of terminal illness and reducing the sorrow experienced by family members. The single insurer model used by the National Health Insurance system will inevitably replace some hospital and institutional services with home health care services that more effectively and flexibly use medical resources and attenuate the increase in medical costs.

Post-acute care for stroke - a retrospective cohort study in Taiwan.

BACKGROUND: Stroke often causes functional decline in patients. Therefore, after the acute phase, many patients require post-acute care (PAC) to maximize their functional progress, reduce disability, and make it possible for them to return to their home and community. PAC can be provided in different settings. Taiwan's National Health Insurance (NHI) proposed a PAC pilot program, effective since 2014, for stroke patients that allowed patients with the potential for functional improvement to receive PAC rehabilitation in regional or community hospitals. The purpose of this study was to explore the initial achievements and clinical impact of this program in Taiwan. METHODS: This was a retrospective cohort study that mainly analyzed basic hospitalization data and scores for function and quality of life, as recorded immediately after admission and before discharge, for stroke patients in the PAC program in a hospital in Taiwan. RESULTS: This study collected complete data from a total of 168 patients. After an average of 43.57 days in the program, patients showed significant improvement in the Modified Rankin Scale (MRS), the Barthel Activity Daily Living Index (B-ADL), the Lawton-Brody Instrumental Activity Daily Living Scale (LB-IADL), the Functional Oral Intake Scale (FOIS), and the Mini Nutrition Assessment (MNA), in mobility, self-care, and usual activity, as well as on anxiety/depression in the EuroQol Five Dimensions Questionnaire (EQ-5D) and in the Mini Mental State Examination (MMSE). After discharge, 76.8% of the patients could return to their home and community. CONCLUSION: This study showed that the pilot PAC program significantly promoted recovery of function in stroke patients and helped them to return to their home and community. Patients with the potential for functional recovery should consider receiving PAC service in a hospital after discharge from acute stroke care.

Discrepancies between leg-to-leg bioelectrical Impedance analysis and computerized tomography in abdominal visceral fat measurement.

The aim of this study was to evaluate leg-to-leg bioelectrical impedance analysis (LBIA) using a four-contact electrode system for measuring abdominal visceral fat area (VFA). The present study recruited 381 (240 male and 141 female) Chinese participants to compare VFA measurements estimated by a standing LBIA system (VFALBIA) with computerized tomography (CT) scanned at the L4-L5 vertebrae (VFACT). The total mean body mass index (BMI) was 24.7 ± 4.2 kg/m2. Correlation analysis, regression analysis, Bland-Altman plot, and paired sample t-tests were used to analyze the accuracy of the VFALBIA. For the total subjects, the regression line was VFALBIA = 0.698 VFACT + 29.521, (correlation coefficient (r) = 0.789, standard estimate of error (SEE) = 24.470 cm2, p < 0.001), Lin's correlation coefficient (CCC) was 0.785; and the limit of agreement (LOA; mean difference ±2 standard deviation) ranged from -43.950 to 67.951 cm2, LOA% (given as a percentage of mean value measured by the CT) was 48.2%. VFALBIA and VFACT showed significant difference (p < 0.001). Collectively, the current study indicates that LBIA has limited potential to accurately estimate visceral fat in a clinical setting.
