RESUMEN
Introduction: Fractures affect people's quality of life especially in the elders. One of the most important risk factors is osteoporosis. There are many screening tools to predict osteoporosis and fractures. We aimed to compare the predictive validity of three commonly used screening tools: fracture risk assessment tool (FRAX), osteoporosis self-assessment tool for Asians (OSTA) and one-minute osteoporosis risk test. Among them, OSTA and one-minute osteoporosis risk test were originally developed to predict osteoporosis risks and FRAX was to predict fracture risks. Methods: This is an 11-year longitudinal study. We enrolled 708 senior people from health examinees in Taiwan in 2010. A standardized questionnaire and blood tests were provided. Annual telephone interview was conducted to assess the real fracture status. We calculated risk scores of FRAX, OSTA, and one-minute osteoporosis risk test and compared with real-world fracture records. Results: The mean age of the participants were 74.9 (SD 6.4). There were 356 (50.3 %) men. From 2010 to 2020, a total of 105 (14.8 %) persons suffered from fractures. Compared to people without fractures, people with fractures had higher FRAX major osteoporotic fracture risk scores (14.0 % ± 7.6 % vs.11.3 % ± 5.7 %), higher hip fracture risk scores, and higher OSTA risk (5.9 % ± 1.4 % vs. 5.3 % ± 1.3 %). Cox regression analysis showed that hazard ratios for fracture of high FRAX risk was 1.53 (95 % confidence interval (CI) 1.05-2.21), and for high OSTA risk was 1.37 (95 % CI 1.04-1.82). Conclusions: Only OSTA and FRAX scores were satisfactory in predicting 10-year fractures.
RESUMEN
Currently, orthopedic surgeons mainly use the inter-teardrop line (IT-line) as the transverse mechanical axis of the pelvis (TAP) for postoperative evaluation of total hip arthroplasty (THA). However, the teardrop is often unclear in the pelvis anteroposterior (AP) radiographs, which makes postoperative evaluation of THA difficult. In this study, we attempted to identify other clear and accurate axes for postoperative evaluation of THA. We calculated the mean and standard deviation of these angles and tested the significance of these angles using t-tests. The inter-teardrops line (IT line) and the upper rim of the obturator foramen (UOF) had smaller angles with the IFH line. The bi-ischial line (BI line) was relatively inaccurate in measurements. We recommend using the IT line as the TAP when the lower boundary of the teardrops is clear and the shapes of the teardrops on both sides of the pelvis are symmetrical. When there is no deformation of the obturator foramen on pelvic AP radiographs, the UOF is also a good choice for the TAP. We do not recommend the BI line as the TAP.
RESUMEN
Objective: An increasing amount of literature indicates that the serum calcium level may be related to metabolic syndrome (MetS) and obesity. This study aimed to examine the relationship between the serum calcium level and MetS in adults in Taiwan. Subjects and methods: We conducted a crosssectional study and enrolled 1,580 participants (54.4% women; mean age, 33.28 ± 12.21 years) who underwent health examinations in northern Taiwan between 2012 and 2016. Logistic regression was performed to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of MetS and its components in groups of patients in the tertiles of the serum calcium level. Results: In total, 167 participants (10.6%) had MetS. The odds of high systolic blood pressure (BP), blood glucose, and triglyceride (TG) levels significantly increased as the serum calcium level increased. Compared with the participants in the lowest tertile of the serum calcium level (tertile 1), those in the second tertile (OR = 1.47, 95% CI: 0.97-2.23) and third tertile (OR = 1.63, 95% CI: 1.06-2.53) had a significantly higher risk of MetS. Further analyses revealed a significant association between MetS and an increased serum calcium level in those in the overweight and obese groups. However, there was no association between the serum calcium levels and MetS in those in the normal weight group. Conclusion: This study demonstrated that a higher serum calcium level is associated with an increased risk of MetS and its components in adults with overweight and obesity.

BACKGROUND: To evaluate the effects of post-acute care (PAC) on frail older adults after acute hospitalization in Taiwan. METHODS: This was a multicenter interventional study. Frail patients aged ≥ 75 were recruited and divided into PAC or control group. The PAC group received comprehensive geriatric assessment (CGA) and multifactorial intervention including exercise, nutrition education, and medicinal adjustments for two to four weeks, while the control group received only CGA. Outcome measures included emergency room (ER) visits, readmissions, and mortality within 90 days after PAC. RESULTS: Among 254 participants, 205 (87.6±6.0 years) were in the PAC and 49 (85.2±6.0 years) in the control group. PAC for more than two weeks significantly decreased 90-day ER visits (odds ratio [OR] 0.21, 95% confidence interval [CI] 0.10-0.43; p = 0.024), readmissions (OR 0.30, 95% CI 0.16-0.56; p < 0.001), and mortality (OR 0.20, 95% CI 0.04-0.87; p = 0.032). Having problems in self-care was an independent risk factor for 90-day ER visits (OR 2.11, 95% CI 1.17-3.78; p = 0.012), and having problems in usual activities was an independent risk factor for 90-day readmissions (OR 2.69, 95% CI 1.53-4.72; p = 0.001) and mortality (OR 3.16, 95% CI 1.16-8.63; p = 0.024). CONCLUSION: PAC program for more than two weeks could have beneficial effects on decreasing ER visits, readmissions, and mortality after an acute illness in frail older patients. Those who perceived severe problems in self-care and usual activities had a higher risk of subsequent adverse outcomes. TRIAL REGISTRATION: ClinicalTrials.gov NCT Identifier: NCT05452395.

BACKGROUND: Melasma is a chronic skin condition that adversely impacts quality of life. Although many therapeutic modalities are available there is no single best treatment for melasma. Oral tranexamic acid has been used for the treatment of this condition but its optimal dose is yet to be established. OBJECTIVES: We used network meta-analysis to determine the optimal dose of oral tranexamic acid for the treatment of melasma. METHODS: We conducted a comprehensive search of all studies of oral tranexamic acid for the treatment of melasma up to September 2020 using PubMed, EMBASE and the Cochrane Library database. The quality of the studies was evaluated using the Jadad score and the Cochrane's risk of bias assessment tool. Only high quality randomised controlled trials were selected. Some studies lacked standard deviation of changes from baseline and these were estimated using the correlation coefficient obtained from another similar study. RESULTS: A total of 92 studies were identified of which 6 randomized controlled trials comprising 599 patients were included to form 3 pair-wise network comparisons. The mean age of the patients in these studies ranged from 30.3 to 46.5 years and the treatment duration ranged from 8 to 12 weeks. The Jadad scores ranged from 5 to 8. The optimal dose and duration of oral tranexamic acid was estimated to be 750 mg per day for 12 consecutive weeks. LIMITATIONS: Some confounding factors might not have been described in the original studies. Although clear rules were followed, the Melasma Area and Severity Index and the modified Melasma Area and Severity Index were scored by independent physicians and hence inter-observer bias could not be excluded. CONCLUSION: Oral tranexamic acid is a promising drug for the treatment of melasma. This is the first network meta-analysis to determine the optimal dose of this drug and to report the effects of different dosages. The optimal dose is 250 mg three times per day for 12 weeks, but 250 mg twice daily may be an acceptable option in poorly adherent patients. Our findings will allow physicians to balance drug effects and medication adherence. Personalized treatment plans are warranted.

RESUMEN
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic can be effectively controlled by rapid and accurate identification of SARS-CoV-2-infected cases through large-scale screening. Hypercube pooling polymerase chain reaction (PCR) is frequently used as a pooling technique because of its high speed and efficiency. We attempted to implement the hypercube pooling strategy and found it had a large quantization effect. This raised two questions: is hypercube pooling with edge = 3 actually the optimal strategy? If not, what is the best edge and dimension? We used a C++ program to calculate the expected number of PCR tests per patient for different values of prevalence, edge, and dimension. The results showed that every edge had a best performance range. Then, using C++ again, we created a program to calculate the optimal edge and dimension required for pooling samples when entering prevalence into our program. Our program will be provided as freeware in the hope that it can help governments fight the SARS-CoV-2 pandemic.

There are many published cup anteversion measurements for postoperative total hip arthroplasty (THA), including Liaw's, Lewinnek's, and Murray's methods. However, most measurements ignore the potential pelvic rotation on radiographs except in Liaw's method. Without considering pelvic rotation, clinicians can miscalculate cup anteversion. Therefore, we aimed to quantify the mean degree of pelvic rotation. Herein, we collected 388 radiographs of 98 postoperative THA hips of 77 patients and measured pelvic rotation by measuring h, the horizontal displacement of the sacrococcygeal junction associated with the upper pole of the symphysis pubis, and ssd, the distance between the sacrococcygeal junction and pubic symphysis. The angle θ of pelvic rotation was defined as θ = arc sin (h/ssd) × (180°/π). The mean degree of pelvic rotation was then calculated. The standard deviation of h was 7.84 mm, and the mean ssd was 158 mm. The potential pelvic rotation was 2.50°. The p-values from the paired t-test were all >0.05 when interobserver and intraobserver errors were assessed. This is the first study to quantify the potential pelvic rotation in the coronal plane on postoperative plain radiographs. The potential pelvic rotation was too large to be neglected during the measurement of cup anteversion.
RESUMEN
Introduction: For patients undergoing THR, measuring the postoperative acetabular anteversion precisely plays a pivotal role in the prognosis. However, using elliptical methods mandates computerized equipment that is frequently in shortage in remote areas and developing countries. We invented a laser projector utilizing the ellipse method to measure the acetabular anteversion directly. The aim is to examine the consistency and validity of the laser projector as compared to our original software, Elliversion. Materials and Methods: We retrospectively collected 50 postoperative pelvis radiographs including acetabulum from our institution. One investigator first measured the anteversion of included radiographs through Elliversion software as the control group. Subsequently, two operators independently used the laser projector for measurements in two separate periods with 1-day intervals as the experimental group. Our analysis was comprised of intra- and inter-observer comparisons and reliability, which investigated both the consistency and validity, by using two-sample student's t-test and intraclass correlation coefficient. Results: There was no significant difference in measuring the anteversion through laser projectors between two operators (p = 0.54), with excellent inter-observer reliability (ICC, 0.967). The estimated effect in the anteversion measurement between the Elliversion and laser projector was also comparable, with the ICC level of 0.984, indicating excellent reliability. Conclusion: Our study reported the consistency and validity of this laser projector as there is no significant difference between Elliversion and Laser projector, notably with excellent intra- and inter-observer reliability. We look forward to helping elevate clinical acumen when doctors provide care to patients after THR, especially in remote areas.
RESUMEN
Distal radius orientation is important in evaluating Colles' fracture. In most cases, the wrist was protected by a bandage, splint, or cast. Therefore, it was difficult for the radiology technician to take perfect anteroposterior and lateral view radiographs. In this study, we build a mathematical model and calculate the pronation angle needed to produce dorsal tilt, which is a volar tilt in a perfect lateral view radiograph. The formulas are all incorporated into Excel to facilitate usage.
RESUMEN
OBJECTIVE: Different lifestyles may contribute to chronic diseases or a health condition. We aimed to study trends in lifestyle habits among community-dwelling older people. METHODS: This retrospective time-trend study enrolled 429 108 participants from the Senior Citizen Health Examination in Taiwan over ten years (2001-2010). We analysed lifestyle habits including smoking, alcohol, betel nut chewing, milk drinking, fruit and vegetable intake, car driving and motorcycle riding. Joinpoint regression was used to identify changes in trend. RESULTS: The overall rate of smoking, alcohol and betel nut chewing was 8.2%, 18.1% and 0.3%, respectively. Smoking rates decreased gradually, but alcohol and betel nut chewing increased. We found that milk drinking, fruit and vegetable intake and car driving initially increased and then later decreased. The change in the trend was in 2003. CONCLUSIONS: There were significant turning points in milk drinking, fruit and vegetable intake and car driving. Implementation of strategies to change the behaviors of citizens about the intake of fruit and vegetable and milk drinking is important.

BACKGROUND: Radial nerve palsy due to humeral shaft fracture is the most common peripheral nerve injury associated with long bone fractures. An antegrade nailing surgical technique is becoming popular for the fixation of these fractures with minimal invasiveness. We analyzed nerve recovery in patients with humeral shaft fracture and radial nerve palsy treated with humeral nail fixation without nerve exploration. AIM: To assess the radial nerve recovery rate and time from humeral shaft fracture with surgical treatment using close nailing. METHODS: We retrospectively collected data of patients who underwent undergone surgical nail fixation for humeral shaft fractures between October 1, 2016, and March 31, 2020. Subsequently, we analyzed the primary or secondary radial nerve palsy recovery rate and radial nerve motor function recovery time. RESULTS: The study included 70 patients who underwent surgical treatment for closed- or Gustilo type I open humeral shaft fractures using a nail fixation technique without radial nerve exploration. The patients suffered from primary (n = 5) and secondary (n = 5) radial nerve palsy. A 100% radial nerve recovery rate was achieved. The mean recovery time was 4.3 mo. CONCLUSION: The study results indicate full recovery of radial nerve palsies from humeral shaft fracture using close nailing treatment. Surgeons need not be concerned about the occurrence of permanent nerve palsies.
RESUMEN
BACKGROUND AND OBJECTIVES: Home visits may change patients' healthcare resource utilisation, including hospital admission, medications, outpatient and emergency room visits. The aim of the present study was to report changes in healthcare resource utilisation after the provision of home healthcare services. METHOD: This was a multicentre follow-up study. Data on health and functional statuses were collected during home visits. Electronic medical records of 12 medical institutions were retrieved (outpatient visits, emergency care use, hospital admissions and prescription medications). The researchers analysed healthcare utilisation and medications before and after enrolment. RESULTS: There were 246 participants. The mean age was 85.5 years (52% men). There was an increase in annual outpatient visits and a decrease in hospital admission days after enrolment (13.7-15.3 visits/year and 17.5-15 days/year, respectively). The number of medical institutions visited increased, but specialties and doctors visited decreased. Oral medications also increased (3.3-4.3 types). DISCUSSION: Home visits help decrease days of hospital admission, but not medications or outpatient or emergency room visits.

To the best of our knowledge, none of Taiwanese studies on the relationship between physical activity (PA) and sarcopenia by the latest 2019 Asian Working Group for Sarcopenia (AWGS) cutoff points of sarcopenia has been published. We used the Taiwan version of international physical activity questionnaire-short version and the 2019 AWGS diagnostic criteria of sarcopenia to examine the relationship between PA and sarcopenia in older adults. Volunteers in this cross-sectional study were recruited from those attending senior health checkup program held at a regional hospital in Taipei City from May 2019 to Sep 2019. Muscle strength was assessed by grip strength, physical performance was assessed by usual gait speed on a 6-m course, and muscle mass was measured by bioelectrical impedance analysis. Multiple logistic regression was used to analyze the relationship between PA and sarcopenia. Odds ratios and corresponding 95% confidence intervals were calculated. 565 participants were recruited and data from 500 participants were used. The study participants had a mean age of 73.87 years old, with 47% men and 53% women. 138 (27.6%) participants were classified as having sarcopenia, among which 48 (45.3%) in low PA participants and 90 (22.8%) in moderate to high PA participants. Compared with those with low PA, moderate to high PA protected against the risk of sarcopenia with the odds ratio (OR) 0.46 (95% CI 0.27-0.79, p-value = 0.005). A significant protective effect of PA on sarcopenia was found among the older adults after adjusting for sex, institutionalization, age, BMI, albumin, hemoglobin, HDL-C levels, history of cardiovascular disease, education level and alcohol drinking.

BACKGROUND: Several cup anteversion measurements for post-operative total hip arthroplasty (THA) surgery have been described. We developed the standardized Liaw's trigonometric method to eliminate the influence of patient position, which is the most accurate method for cup anteversion measurement. We then developed an ellipse method using the Elliversion software and reported an interobserver error reduction in 2013. In this study, we attempted to apply this ellipse method in the clinic and compared its accuracy with the standard trigonometric version. METHODS: In the present study, we attempted to incorporate the ellipse method with Liaw's standardized anteversion in the simulated cup position. We measured standardized Liaw's anteversion for 434 radiographs in the clinic using the ellipse method. Repeated standard deviation (RSD) was calculated for accuracy evaluation. Furthermore, paired t-test was used for comparison with the interobserver and intraobserver errors. RESULTS: We found that the standardized Liaw's anteversion measured using the ellipse method showed lower RSD than the radiographic version. RSD was 0.795 in the standardized Liaw's anteversion with ellipse method group. The p-values of the paired t-test were all higher than 0.05 when measuring the interobserver and intraobserver errors. It indicated that the ellipse method was a precise and simple tool for cup anteversion measurement. CONCLUSION: We believe that this ellipse measurement can assist surgeons while placing the acetabulum cup into the precise position and enable early diagnosis of acetabulum loosening.

BACKGROUND: Mismatch of intramedullary nails with the bowing of femur is a frequent clinical finding. Previous studies showed inconsistent results. METHODS: We present an algorithm of region growing territory method to get the radii of the anterior bowing of femur. We also tested it on ten radiographs. Plain radiographs of the lateral view of femur from five men and five women taken between January and August 2014 in Taipei Hospital were chosen randomly. The curvature of femur outline and medullary canal were measured for three times each. Radii of curvature of whole femur, proximal, middle and distal parts were calculated and analyzed. RESULTS: The coefficient of variation of the 240 measurements ranged from 0.007 to 0.295 and averaged 0.088. The average radii of curvature of the whole, proximal, middle, and distal femur were 1318 mm, 752 mm, 1379 mm, and 599 mm, respectively. At the distal part of the femur, the radius of curvature of the femur outline (452 mm) was smaller than the medullary canal (746 mm) (p < 0.05). Women's femur was straighter than men's when we compared the whole length (1435 mm vs. 1201 mm, p < 0.05). The radii we calculated were smaller than the current intramedullary nails. CONCLUSION: The results showed that the inter-observer and intra-observer differences are acceptable, support the impression that different bowing conditions existed for Asians as compared to Caucasians, and also indicate the mismatch of current instruments to the curvature of femur.
RESUMEN
BACKGROUND AND PURPOSE: There has been much discussion about the risk factors for osteoporosis, but studies involving elderly population in Taiwan are minimal. We aimed to describe variables related to osteoporosis among community dwelling older people in Taiwan. METHODS: This is a cross-sectional study. The 671 participants were randomly selected from 3680 examinees of the annual Senior Citizens Health Examination in year 2010. Participants were interviewed with a detailed questionnaire, and 91 of them were invited for dual-energy X-ray absorptiometry (DXA). Predictor variables included age, gender and clinical risk factors for osteoporosis. The main outcome was osteoporosis confirmed by DXA. RESULTS: The mean age of the participants was 75.7±6.4years old. Overall, the most prevalent variables for osteoporosis were height loss in adulthood (41.0%), lack of dairy products or calcium supplements (32.0%) and insufficient physical activity (10.4%). In multivariate models, we found that underweight (OR=9.80) and lack of dairy products/calcium supplements (OR=3.68) were the main variables for osteoporosis. In the subgroup analysis involving only women, underweight (OR=14.60) was the main variable. DISCUSSION: Among community-dwelling older people in Taiwan, osteoporosis was mainly associated with underweight and lack of dairy products or calcium supplements. CONCLUSION: We suggest using the key questions of underweight and dietary pattern in clinical settings to identify high risk people who are candidates for further BMD exam.

OBJECTIVES: There is no gold standard in diagnosing sarcopenia. We aimed to assess the validity of screening sarcopenia using SARC-F (sluggishness, assistance in walking, rise from a chair, climb stairs, falls). DESIGN: Prospective cohort study. SETTING: Community hospital in Taiwan. PARTICIPANTS: Community-dwelling senior citizens. MEASUREMENTS: Participants were interviewed with a structured questionnaire annually. The questionnaire items were recoded into the 5 items of SARC-F (sluggishness, assistance in walking, rise from a chair, climb stairs, falls). In the baseline year, a subgroup was tested for grip strength and body composition. Healthcare utilization and mortality were based on self-report and hospital records. Our main outcome was 4-year mortality. Secondary outcomes included hospitalization, emergency care use, and quality of life (QOL) measured using the CASP-12 scale (control, autonomy, self-realization, pleasure (control, autonomy, self-realization, pressure). RESULTS: There were 670 participants. The mean age was 76.1 (standard deviation 6.36). One-half were men (n = 340, 50.7%). The prevalence of sarcopenia was 6.1% (n = 41). SARC-F scores were inversely associated with grip strength (P = .001) and skeletal muscle composition (P = .045). Participants with sarcopenia were mostly women (P = .005) and older (P < .001). In univariate analysis, sarcopenia was associated with 1- to 4-year mortalities (P = .033, .001, .001, <.001, respectively), overall hospitalization (P = .004), overall emergency care use (P = .017), and QOL (P < .001). In multivariate model, sarcopenia [odds ratio (OR) 7.35, 95% confidence interval (CI) 2.67-20.18], age (OR 1.19, 95% CI 1.09-1.29 for each year), and taking vitamin D supplements (OR 0.29, 95% CI 0.11-0.74) were factors associated with mortality. CONCLUSIONS: Sarcopenia screened using SARC-F was associated with subsequent QOL, overall hospitalization, overall emergency care use, and 4-year mortality. SARC-F can serve as a quick screening tool of sarcopenia.

BACKGROUND: The Taiwanese government increased financial subsidies for smoking cessation services in 2012. We aimed to evaluate the effects of this new policy on smoking cessation services from the physician's perspective. METHODS: This was a cross-sectional nationwide survey. Physicians who provided smoking cessation services for more than ten patient encounters in the preceding year of the new policy (February 2011 to March 2012) were recruited. The questionnaire was developed by two experts and was validated by a committee consisting of 11 delegates. RESULTS: We sent a total of 1,319 questionnaires. The response rate was 45.9 %. The majority of respondents were male (88.4 %), middle-aged (65.3 %), and worked as family physicians (56.1 %). Most physicians agreed that the new policy had increased the number of patients seeking smoking cessation, increased patients' willingness to adopt pharmacotherapy, helped physicians to prescribe medications, improved patients' adherence to medications, and improved quality of care. These changes were most prominent in medical centers. Changes in the practice of the 5As (ask, advise, assess, assist, arrange) were moderate. Among different medical settings, the most significant change was an increase in the expenditure on smoking cessation medications. CONCLUSIONS: The new subsidization policy in Taiwan has improved smoking cessation services. Overall, physicians reported positive effects of the new policy. Further study is warranted to evaluate the long-term influence of the policy.

Measuring bone angles is an important method for diagnosing disease and predicting the prognosis in orthopedics. Traditionally, the angle is measured using lines drawn manually and adjusted by the naked eye. The purpose of the present study was to propose new methods to measure the bone angles formed by the axes of the calcaneus with good reliability and low operational error. The 2 new methods used linear regression analysis of the points inside and on the "envelope" line. The traditional method used the vector of the lines drawn for calculation. Digital radiographs of the lateral view of the feet from 51 patients were collected, and the angles were measured using these 3 methods. Next, we analyzed the reliability, differences, and correlations of these 3 methods. The intra- and interobserver comparisons revealed significant differences between the results of the 2 new methods and those of the traditional method. In addition, the new methods had greater reliability and better intra- and interobserver correlations than did the traditional method. We suggest that these 2 new methods to measure bone axis should be added to the Picture Archiving and Communication System to obtain more reliable and standardized data in clinical practice and for future research purposes.
