Abstract
PURPOSE Several studies have investigated the factors that influence health-related quality of life in patients with knee osteoarthritis (KOA). This study aimed to identify and investigate the degree of involvement of potential factors influencing health-related quality of life (HRQOL) in an aged population with or without KOA. METHODS This multi-centered study included 651 participants who underwent health checkups in rural areas of Japan in 2010. The association between three component summary score of short-form 12 (physical component summary; PCS, mental component summary; MCS, and role-social component summary; RCS) and covariates were investigated using multiple linear regression model and calculated the scaled estimated regression coefficient. RESULTS Decreasing mobility, severity of knee pain, high pain-related self-efficacy (PSE), older age, high functional self-efficacy (FSE), and female gender had significant effect on PCS (p < 0.05). However, radiographic KOA had no influence on PCS. Presence of depression and body mass index had a significant influence on the MCS (p < 0.05). Decreasing mobility, presence of depression, PSE and older age had significant influence on the RCS (p < 0.05). CONCLUSION Our study results showed that physical, mental, and role/social QOL were affected by different influencing factors. Physical QOL was strongly influenced by subjective pain, physical performance, and self-efficacy, whereas radiographic KOA had no such effect. Depressive mood is associated with both mental and role/social QOL. The role/social QOL was predominantly affected by physical function and pain-related self-efficacy. Taking measure to improving functional ability and mental status might be the key factor to improve HRQOL in patient with KOA. LEVEL OF EVIDENCE Level 3: Epidemiologic cross-sectional study (prognostic study).

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
BACKGROUND The flexor pronator muscles (FPMs) have been reported to act as dynamic stabilizers against valgus forces in overhead-throwing athletes. Several studies have demonstrated the anatomic, biomechanical, and clinical effects of the FPMs. However, no studies have investigated the in vivo kinematics of the FPMs against the valgus forces on the elbow. This study aimed to clarify the clinical contribution of the FPMs as dynamic stabilizers in medial ulnar collateral ligament (MUCL) insufficiency. METHODS Eighteen baseball players with MUCL injury participated in this study. The elbow was flexed to 90°, and the forearm was placed in the supinated position. Manual valgus stress was applied to the elbow joint until maximal shoulder external rotation was achieved. The width of the ulnohumeral joint space was measured using ultrasonography, and any changes in medial elbow pain were recorded before and after isometric forearm pronation. RESULTS All the subjects had MUCL tenderness and felt medial elbow pain when elbow valgus stress was applied. The width of the medial joint space was significantly larger on the injured side than on the healthy side (5.1 ± 1.0 mm vs. 3.2 ± 1.0 mm) with elbow valgus stress. During isometric forearm pronation, the width of the medial joint space was significantly decreased (3.1 ± 0.9 mm vs. 2.6 ± 1.0 mm) and medial elbow pain had completely diminished. CONCLUSION Isometric forearm pronation reduces valgus stress-induced widening of the medial joint space and medial elbow pain in patients with MUCL insufficiency.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
Background This study aimed to investigate the effect of chronic traction apophysitis of the medial epicondyle (MEC) on medial ulnar collateral ligament (MUCL) insufficiency in high school baseball players. Methods In this retrospective cohort study, 3034 of 6069 high school baseball players were enrolled. A self-reported questionnaire was distributed to investigate past history of elbow pain and elbow pain during the previous season. Physical examinations to assess tenderness on the MUCL and the elbow valgus stress test (EVST) were performed. Ultrasonography was performed to determine the presence of morphological abnormalities of the anteroinferior aspect of the MEC (MEC lesions). Results Participants with MEC lesions had a significantly higher prevalence of past history of elbow pain, elbow pain during the previous season, MUCL tenderness, and positive EVST than those without MEC lesions (P < .05). Multivariate logistic regression analysis revealed that the participants with the fragmented type had the highest risk of past history of elbow pain (odds ratio [OR] = 3.94), elbow pain during the previous season (OR = 2.27), positive EVST (OR = 3.49), and the second highest risk of MUCL tenderness (OR = 2.01) followed by the irregular type (OR = 2.31). Participants with the hypertrophic type had the lowest risk of past history of elbow pain (OR = 2.08), elbow pain during the previous season (OR = 1.42), MUCL tenderness (OR = 1.09), and positive EVST (OR = 1.47). Conclusion The presence of chronic non-healed traction apophysitis of the MEC in high school baseball players presented a significantly high risk of elbow pain and MUCL insufficiency.

Abstract
PURPOSE To determine normal corneal eccentricity in a rural Japanese population and to examine factors associated with eccentricity value. METHODS This used data from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) project between 2009 and 2012. Residents of Minamiaizu and Tadami in Fukushima, Japan, who were aged 40 years or over, were invited for a comprehensive eye examination. For 1371 patients with no history of internal eye surgery, corneal eccentricity was measured using a Pentacam. RESULTS Of 1371 people recruited to the study, 1215 (1215 eyes) met the inclusion criteria. The overall mean eccentricity was 0.46 (SD = 0.18; range, -0.85 to 0.88). Corneal eccentricity was significantly associated with age, spherical equivalent, pupil diameter, anterior chamber angle, anterior chamber volume, and central corneal thickness, but not with gender or body mass index. CONCLUSIONS In this study, the normal cornea in this Japanese population was prolate. Corneal eccentricity was likely to decrease with increasing age. Also, spherical equivalent and other anterior segment parameters had an influence on corneal eccentricity. Corneal eccentricity measurements might be helpful in the diagnosis of corneal diseases and in calculations for intraocular lens implantation and corneal refractive surgery.

Abstract
PURPOSE To investigate the prevalence and factors associated with uncorrected presbyopia among rural community dwellers in Japan. STUDY DESIGN A population-based cross-sectional study was conducted in 2011 among community dwellers aged 40-74 years who received specific health checkups in Minamiaizu and Tadami, Fukushima Prefecture, Japan. METHODS Uncorrected presbyopia was considered as when the distance-corrected visual acuity in the better eye was ≥0.5 and the near-presenting visual acuity in the better eye was <0.4, regardless of distance refractive status. Multiple logistic regression analysis was employed to calculate the odds ratios (ORs) for uncorrected presbyopia and to adjust for possible confounders. RESULTS A total of 2054 individuals participated in the specific health checkups. In the 1156 individuals (response rate: 56.28%) analyzed in the study, the mean (SD) age was 63.0 (8.7) years, the percentage of women was higher (57.87%), and the prevalence of uncorrected presbyopia was 26.38% (95% CI 23.86%-29.03%). Multivariate analysis revealed that the factors associated with uncorrected presbyopia were older age (adjusted OR: 1.054 [95% CI: 1.034-1.075]), female sex (adjusted OR: 1.388 [95% CI: 1.006-1.915]), and distance-presenting vision impairment (adjusted OR: 2.651 [95% CI: 1.697-4.143]). CONCLUSION Approximately one-quarter of the participants in this study from a rural population of Japan did not have adequate near vision. It is recommended that a public health intervention should be enacted to correct presbyopia, especially in the older age group, women, and those with uncorrected refractive errors.

Abstract
Arthroscopic debridement for elbow osteoarthritis has been widely used as a minimally invasive treatment; however, in some cases, it can be a technically demanding procedure, such as in patients with severe osteoarthritis with large spur formation and severe synovitis. The anterocentral transbrachialis portal is a recently developed portal for elbow arthroscopy, which allows easy and convenient access to the anterior compartment for sufficient debridement. This report describes in detail the anterocentral transbrachialis portal and its usefulness for debridement of the elbow joint in osteoarthritis.

Background
Elevated left ventricular (LV) filling pressure is an important diagnostic feature of heart failure.
Objectives
To investigate determinants of left atrial (LA) reservoir and pump strain and if these parameters may serve as markers of LV filling pressure.
Methods
In a multicenter study of 322 patients with cardiovascular disease of different etiologies, LA strain by speckle tracking echocardiography was compared to conventional echocardiographic markers using invasive pressure as reference.
Results
Left ventricular filling pressure correlated well with LA reservoir and pump strain (r-values
‑0.52 and ‑0.57, respectively) (Figure). However, LV global longitudinal strain (GLS) was the strongest determinant of LA reservoir strain (r = 0.64), and correlated well with LA pump strain (r = 0.51). For both LA strains, association with filling pressure was strongest in patients with reduced LV ejection fraction. In patients with normal GLS (≥18%), atrial strains provided no information regarding filling pressure (Figure). Reservoir strain <18% and pump strain <8% predicted elevated LV filling pressure better (p < 0.05) than the conventional indices LA volume, ratio of mitral early filling velocity/annular velocity and tricuspid regurgitation velocity. Accuracy to classify filling pressure as normal or elevated was 75% for both LA strains . When any one of the conventional indices were missing, and were replaced by LA strains, the combination of indices had accuracy 82% to correctly classify filling pressure.
Conclusions
Left atrial reservoir and pump strain may serve as clinical markers of LV filling pressure, but will be useful predominantly in patients with reduced systolic function. Due to limited diagnostic accuracy, LA strain should be used in combination with other indices.

Abstract
Abstract
Background
When evaluating left ventricular filling pressure (LVFP) according to current guidelines, tricuspid regurgitation (TR) velocity is often not available.
Purpose
In the present study we investigate if left atrial (LA) reservoir strain may be used instead of TR velocity for evaluation of LVFP.
Methods
We performed a prospective, multicenter, multinational and multivendor study in an all comer population of 322 patients with suspected heart failure or other cardiovascular disease where LVFP was measured by right- or left heart catheterization, as pulmonary capillary wedge pressure or pre-A LV diastolic pressure, respectively. Echocardiography was performed within 1 day of catheterization.
101 patients classified as special populations in the 2016 ASE/EACVI recommendations (i.e. non-cardiac pulmonary hypertension, atrial fibrillation, hypertrophic and restrictive cardiomyopathies) were excluded. Of the remaining 221 patients, 118 patients had EF ≥50% and 103 patients had EF <50%. Regression analysis was performed for LA reservoir strain and TR velocity against LVFP. LA reservoir strain at a cut-off value of <18% was applied instead of TR velocity in the 2016 ASE/EACVI algorithm and compared with the current algorithm.
Results
LA reservoir strain correlated better with LVFP than TR velocity, r=0.62 vs 0.40 (p<0.01) (Figure 1). When replacing TR velocity with LA reservoir strain, the feasibility of the ASE/EACVI 2016 algorithm increased from 91.8% to 98.1%. The accuracy of the algorithm was not significantly altered (80% vs 79%).
An accuracy of 80% for the algorithm is lower than what has been reported in earlier publications, this may be due to inclusion of patients without suspected heart failure and no assessment of clinical data, which in turn may have influenced the accuracy of the algorithm.
Conclusion
LA reservoir strain has better correlation to LVFP than TR velocity, and can be used in the ASE/EACVI 2016 algorithm for estimation of LVFP as a replacement when TR velocity is missing.

Abstract
Abstract
Background
Estimation of left ventricular filling pressure (LVFP) is highly relevant in clinical practice. Invasive pressure remains the gold standard, but a number of echocardiographic parameters that correlate with LVFP are used as non-invasive markers of pressure.
Purpose
We investigated how different echocardiographic parameters correlated with invasively measured LVFP, and how accurately those parameters could differentiate between normal or elevated LVFP.
Method
We performed a prospective, multicenter, multinational and multivendor study in an all comer population of 322 patients with suspected heart failure or other cardiovascular disease. 194 patients had EF ≥50% and 129 had EF <50%. LVFP was measured by right- or left heart catheterization, as pulmonary capillary wedge pressure or pre-A LV diastolic pressure, respectively.
When excluding all special patient populations defined in the 2016 recommendations for echocardiographic evaluation of LV diastolic function, 213 patients remained. Of these 135 had EF ≥50% and 74 had EF <50%.
Echocardiography was performed within 1 day of catheterization. Previously recommended cut-off values for established parameters were used to determine the accuracy of classifying LVFP as normal or elevated. For left atrial (LA) reservoir strain, based on ROC analysis, a cut-off value of <18% was used as marker of elevated LVFP.

LA reservoir strain and the ratio of peak mitral early flow velocity (E) and LA reservoir strain (E/LA strain) showed the best correlations to LVFP (Table 1, Figure 1). They also had the highest accuracy, 75% for both, in classifying LVFP as normal or elevated in the whole patient population. E/LA reservoir strain provided no additional diagnostic value to using LA reservoir strain alone.
In HFpEF patients accuracy was essentially similar for LA strain, E/LA strain and E/e', whereas in HFrEF patients the two former tended to be better than E/e'.
Conclusion
Parameters containing LA reservoir strain showed the best correlation to LVFP. This indicates that LA reservoir strain may have a role in evaluation of LVFP.

Abstract
Using only cosmic microwave background polarization data from the polarbear experiment, we measure B-mode polarization delensing on subdegree scales at more than 5σ significance. We achieve a 14% B-mode power variance reduction, the highest to date for internal delensing, and improve this result to 22% by applying for the first time an iterative maximum a posteriori delensing method. Our analysis demonstrates the capability of internal delensing as a means of improving constraints on inflationary models, paving the way for the optimal analysis of next-generation primordial B-mode experiments.

Abstract
The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on Impactor. The impact produced an artificial crater with a diameter >10 meters, which has a semicircular shape, an elevated rim, and a central pit. Images of the impact and resulting ejecta were recorded by the Deployable CAMera 3 for >8 minutes, showing the growth of an ejecta curtain (the outer edge of the ejecta) and deposition of ejecta onto the surface. The ejecta curtain was asymmetric and heterogeneous and it never fully detached from the surface. The crater formed in the gravity-dominated regime; in other words, crater growth was limited by gravity not surface strength. We discuss implications for Ryugu's surface age.

Abstract
Abstract
Background and Purpose
It is important to evaluate exercise capacity to detect the development of heart failure (HF) in patients with heart disease. The pathology of exercise capacity is multi-factorial, and cardiac function is recognized as one of the most important determinants. However, the correlation between right ventricular (RV) function and exercise capacity is not fully understood in the subjects without HF. Therefore, we assessed the relationship between RV function and exercise capacity, both in patients with HF (HF+) and in patients with heart disease but not developed HF (HF-).
Methods
Two hundred and fifty-two patients with heart disease who underwent both Doppler echocardiography at rest and cardio-pulmonary exercise testing (CPET) for the assessment of heart function were enrolled (HF+: n = 142, HF-: n = 110). We measured left ventricular ejection fraction (LVEF), peak early diastolic transmitral flow velocity (E), peak late diastolic transmitral flow velocity (A), early diastolic mitral annular velocity (e’), left atrial volume (LAV), and tricuspid annular plane systolic excursion (TAPSE) by echocardiography. After echocardiographic examination, symptom-limited exercise testing was performed with simultaneous respiratory gas analysis, and peak oxygen consumption (pVO2) was determined. Blood examination including hemoglobin (Hb) and brain natriuretic peptide (BNP) was done on the same day.
Results
There were significant relationships between pVO2 and LVEF (r = 0.16, p = 0.005), e" (r = 0.51, p < 0.0001), E/e" (r=-0.47, p < 0.0001), LAV (r=-0.21, p = 0.0002), and TAPSE (r = 0.33, p < 0.0001) in the whole subjects. In the multiple regression analyses, age, Hb, E/e" and TAPSE were selected as significant determinants for pVO2 both in HF+ (R²=0.39, p < 0.0001) and HF- (R²=0.33, p < 0.0001).
Conclusion
RV function is the prime determinant of exercise capacity in patients at risk of HF, as well as in patients with HF.

Abstract
AIM This study evaluated the relationship between three-dimensional (3D) mean computed tomography (CT) attenuation values of ground-glass nodules (GGN) and pathological invasiveness in early lung adenocarcinoma. The diagnostic accuracy of 3D CT attenuation values was compared with that of two-dimensional (2D) CT attenuation values and standardised uptake value on positron-emission tomography (PET). MATERIALS AND METHODS Surgical and radiological data from 96 pure or part-solid GGNs of <20 mm were analysed retrospectively. Mean 2D and 3D CT attenuation values of the tumours were obtained with semi-automated volumetric software. Pathological invasiveness was diagnosed according to the International Association for the Study of Lung Cancer (IASLC))/American Thoracic Society (ATS)/European Respiratory Society (ERS) classification. Pre-invasive lesions and minimally invasive adenocarcinomas were classified as non-invasive adenocarcinoma. Univariate and multivariate analyses determined relationships between pathological invasiveness and clinical/radiological findings. Receiver operating characteristic (ROC) analysis was performed to determine the optimal cut-off value for detecting invasive adenocarcinoma. RESULTS A total of 66 non-invasive and 30 invasive adenocarcinoma cases between 2010 and 2016 were analysed. Univariate analysis revealed four tumour invasiveness-associated predictors: maximum diameter, SUVmax, mean 2D CT attenuation value, and mean 3D CT attenuation value (p<0.05). Multivariate analysis revealed that the maximum diameter, SUVmax, and mean 3D CT attenuation value were significant predictors of pathological invasiveness (p=0.023, 0.022, 0.004). The area under the ROC curve to predict invasive adenocarcinoma for mean 3D CT attenuation value was 0.838 and the cut-off value was -489 HU. CONCLUSION The mean 3D CT attenuation value could distinguish pre-invasive lesions and minimally invasive adenocarcinoma from invasive adenocarcinoma.

Abstract
Abstract
Background
Low muscle mass with or without fat mass is a main component of cachexia in heart failure (HF) and associated with poor prognosis. There is a paucity of data, however, regarding prognostic impact of each component of body composition (i.e., muscle, fat, and bone mass).
Purpose
We hypothesized that muscle, fat, and bone mass have different impact on prognosis in HF.
Methods
We retrospectively analyzed 418 patients admitted with a diagnosis of HF (71±13 years, 59% male, 46 and 54% with preserved/mid-range (left ventricular ejection fraction (LVEF) ≥40%) and reduced (<40%) LVEF), respectively). Dual-energy X-ray absorptiometry was performed at stable state after decongestion therapy.
Results
Mean appendicular skeletal mass index (ASMI) was 6.9±1.2 kg/m2 in men and 5.6±0.9 in women, so that 55% of patients had low muscle mass categorized by the Asian Working Group of Sarcopenia. During median follow-up of 502 days, 163 (39.0%) patients experienced primary outcome defined as death or heart failure hospitalization. Using optimal cut-off of each body component chosen on the basis of a receiver operating characteristic curve and the Youden method, we demonstrated that lower ASMI defined by the cut-off of 6.5 kg/m2 in male and 5.2 in female (adjusted hazard ratio (HR): 1.768, 95% CI: 1.210–2.581, p=0.003) and bone mass (adjusted HR: 1.498, 95% CI: 1.051–2.152, p=0.025), but not lower fat mass (p=0.34), were associated with elevated risk of primary outcome after multivariate adjustment. Kaplan-Meier curves with p value by Log-rank test were shown in figure. In subgroup analysis, negative impact of lower ASMI was significant regardless of sex and LVEF category, whereas negative impact of low bone mass was significant only in 78 female patients with reduced LVEF.

Conclusions
Indices about muscle and bone mass rather than fat mass had prognostic impact in HF. The impact of each body component may different according to sex and LVEF.

Abstract
BACKGROUND Several guidelines for the prevention of throwing injuries recommend a sufficiently long off-season; however, few studies providing scientific evidence to support these recommendations exist. Our study aimed to clarify the association between off-season duration and throwing elbow injuries among elementary school-aged baseball players. METHODS This study enrolled 680 elementary school-aged baseball players who underwent medical checkups. The experience with elbow pain and the off-season duration were investigated via the administration of a self-completed questionnaire. Ultrasonographic assessment of the elbow joint was performed on the day of the medical checkup to assess for morphologic abnormalities. RESULTS The prevalence of elbow pain and morphologic abnormalities of the medial epicondyle (medial epicondyle lesions) was significantly decreased when the subjects' off-season duration was longer. Multivariate analysis revealed that the risk of elbow pain was significantly lower in the group whose off-season lasted 1 to 2 months (odds ratio [OR], 0.32; 95% confidence interval [CI], 0.15-0.62; P = .0006) and in the group whose off-season lasted longer than 2 months (OR, 0.59; 95% CI, 0.37-0.95; P = .0316). The risk of medial epicondyle lesions was also significantly lower in the group whose off-season lasted 1 to 2 months (OR, 0.39; 95% CI, 0.22-0.67; P = .0005) and in the group whose off-season lasted longer than 2 months (OR, 0.36; 95% CI, 0.23-0.56; P < .0001). On the contrary, no significant correlation was found between capitellar osteochondritis dissecans and off-season duration. CONCLUSION Off-season duration has a significant correlation with elbow pain and morphologic abnormalities of the medial elbow joint in elementary school-aged baseball players.

Abstract
The Hayabusa2 spacecraft arrived at the near-Earth carbonaceous asteroid 162173 Ryugu in 2018. We present Hayabusa2 observations of Ryugu's shape, mass, and geomorphology. Ryugu has an oblate "spinning top" shape, with a prominent circular equatorial ridge. Its bulk density, 1.19 ± 0.02 grams per cubic centimeter, indicates a high-porosity (>50%) interior. Large surface boulders suggest a rubble-pile structure. Surface slope analysis shows Ryugu's shape may have been produced from having once spun at twice the current rate. Coupled with the observed global material homogeneity, this suggests that Ryugu was reshaped by centrifugally induced deformation during a period of rapid rotation. From these remote-sensing investigations, we identified a suitable sample collection site on the equatorial ridge.

Abstract
The near-Earth carbonaceous asteroid 162173 Ryugu is thought to have been produced from a parent body that contained water ice and organic molecules. The Hayabusa2 spacecraft has obtained global multicolor images of Ryugu. Geomorphological features present include a circum-equatorial ridge, east-west dichotomy, high boulder abundances across the entire surface, and impact craters. Age estimates from the craters indicate a resurfacing age of [Formula: see text] years for the top 1-meter layer. Ryugu is among the darkest known bodies in the Solar System. The high abundance and spectral properties of boulders are consistent with moderately dehydrated materials, analogous to thermally metamorphosed meteorites found on Earth. The general uniformity in color across Ryugu's surface supports partial dehydration due to internal heating of the asteroid's parent body.

Abstract
OBJECTIVES A discrepancy in self-reported and performance-based physical functioning levels is often observed among older adults. We investigated the association of discrepancy in self-reported and performance-based physical functioning levels with risk of future falls among community-dwelling older adults. DESIGN Prospective cohort study. SETTING Two communities in Fukushima Prefecture, Japan. PARTICIPANTS 1379 older adults who took part in the yearly health checkup in both 2009 and 2010. MEASURES The performance-based and self-reported physical functioning levels were evaluated by the Timed Up and Go test and the Short-Form 12 Health Survey (Japanese version) physical functioning subscale, respectively. We divided the participants into 4 groups based on the combinations of low or high performance-based and self-reported physical functioning groups, which were classified by age- and sex-specific reference values. The main outcome was the occurrence of any falls within the 1-year follow-up period, assessed using a self-reported questionnaire. RESULTS A total of 22% of the participants reported the occurrence of a fall during the follow-up period. In multivariable logistic regression analysis, the adjusted odds ratios of the high self-reported and low performance-based, low self-reported and high performance-based, and low self-reported and low performance-based physical functioning groups were 1.10 (95% confidence interval [CI], 0.67-1.82), 1.76 (95% CI, 1.17-2.66), and 1.80 (95% CI, 1.11-2.90), respectively, compared with the high self-reported and high performance-based physical functioning group. CONCLUSIONS Our findings suggest that the discrepancy as high performance-based but low self-reported physical functioning level is associated with an increased risk of future falls in older adults aged 65-89 years. Clinicians should carefully assess older adults whose subjective perception of their physical functioning capacity is lower than those in similar age and sex groups, even if their actual physical functioning appears to be objectively high.

Abstract
BACKGROUND Various shoulder disorders have been reported to be associated with scapulothoracic joint dysfunction in adult overhead athletes. However, little is known about the prevalence of scapular malalignment and its relationship to shoulder injuries in skeletally immature baseball players. The purpose of the current study was to investigate the prevalence of scapular malalignment in elementary school-aged baseball players, as well as its association with shoulder disorder. METHODS One hundred sixty-nine baseball players in higher elementary school grades (aged 11-12 years) were enrolled in this study. Shoulder pain experience pain over the previous one year, as well as other individual and environmental factors were surveyed by a self-completed questionnaire. Scapula malalignment was assessed using still images of both arms both at the side and in an elevated position. The relative position of the dominant scapula to the non-dominant side was assessed by two independent examiners. RESULTS Scapular malalignment was observed in 126 subjects (74.6%), and the dominant scapula tended to deviate inferiorly and medially, as well as tilt anteriorly, compared with the non-dominant side. Forty-four of the 169 subjects (23.8%) experienced shoulder pain over the one year period. The prevalence of shoulder pain was significantly increased with the increasing scapular anterior tilt and the superior shift of the dominant scapula, whereas no significant correlation between shoulder pain and scapular horizontal shift or upward-downward rotation was observed. CONCLUSION About three-quarters of the elementary school-aged baseball players in the current study presented with scapular malalignment, and those with anterior tilt and superior shift of the dominant scapula were at higher risk of shoulder pain.

Abstract
BACKGROUND Laminoplasty is widely accepted as a standard treatment of cervical compressive myelopathy. However, due to the risk of postoperative complications such as neck symptoms, segmental partial laminectomy (SPL) is performed instead, which results in fewer postoperative symptoms. The aim of this study was to describe the difference in the incidence and severity of postoperative neck symptoms between traditional C3-C7 expansive open-door laminoplasty (ELAP) and SPL. METHODS A retrospective and comparative study was performed regarding neck complications following the two surgical procedures. Twenty patients underwent SPL, and an additional 20 age- and gender-matched patients underwent traditional C3-C7 ELAP. Preoperative and postoperative JOA scores were measured, and postoperative neck symptoms in both groups were evaluated using a self-administered questionnaire, according to the Neck Pain and Disability Scale. RESULTS The total incidence of postoperative neck symptoms in the SPL group was similar to that in the ELAP group; however, the severity of symptoms was remarkably lower in the SPL group than in the ELAP group. CONCLUSIONS SPL seems to be a better procedure for reducing postoperative neck symptoms, when compared with C3-C7 ELAP.

Abstract
Background Falls and fall-related fractures are a major public health problem among the older adults. Although objective measures of poor vision have been reported to be associated with falls, the association of self-reported visual function and vision-specific quality of life (QOL) with falls has been inconsistent across several studies. We investigated the association of self-reported visual function and vision specific QOL with falls in community-dwelling older adults. Methods We conducted a cross-sectional analysis using the baseline data from participants of the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS), which is an ongoing population-based cohort study to evaluate the association of physical dysfunction with the clinical outcomes in community-dwelling people. In the present study, the participants aged over 65 years in 2010 were eligible. The exposure variable was the composite score of the VFQ-J11, which was newly developed using item response theory to evaluate vision specific QOL, and the self-reported outcomes were any fall and frequent falls (≥2) over a 1-month period. We estimated odds ratios using separate logistic regression models adjusted for relevant confounding factors. Results Among 1624 participants, the median (interquartile range) composite score of VFQ-J11 was 86.8 (76.0–95.9). Any fall and frequent falls were reported by 13.9% and 5.4% of participants, respectively. The composite score of the VFQ-J11 was significantly associated with both frequent falls (adjusted ORs per 10 points, 0.80; 95% CI, 0.68–0.93) and any fall (adjusted ORs per 10 points, 0.84; 95% CI, 0.76–0.94). Conclusions We found that the composite score of the VFQ-J11 was associated with falls in community-dwelling older adults. Detecting individuals with visual impairments associated with falls using the VFQ-J11 and improvement in the score by interventions could prevent falls. We may consider adding self-reported visual function and vision-specific QOL to conventional risk factors for fall among older adults.

Abstract
BACKGROUND Genome-wide association studies (GWASs) have revealed relationships between over 57,000 genetic variants and diseases. However, unlike Mendelian diseases, complex diseases arise from the interplay of multiple genetic and environmental factors. Natural selection has led to a high tendency of risk alleles to be enriched in minor alleles in Mendelian diseases. Therefore, an allele that was previously advantageous or neutral may later become harmful, making it a risk allele. METHODS Using data in the NHGRI-EBI Catalog and the VARIMED database, we investigated whether (1) GWASs more easily detect risk alleles and (2) facilitate evolutionary insights by comparing risk allele frequencies of different diseases. We conducted computer simulations of P-values for association tests when major and minor alleles were risk alleles. We compared the expected proportion of SNVs whose risk alleles were minor alleles with the observed proportion. RESULTS Our statistical results revealed that risk alleles were enriched in minor alleles, especially for variants with low minor allele frequencies (MAFs < 0.1). Our computer simulations revealed that > 50% risk alleles were minor alleles because of the larger difference in the power of GWASs to differentiate between minor and major alleles, especially with low MAFs or when the number of controls exceeds the number of cases. However, the observed ratios between minor and major alleles in low MAFs (< 0.1) were much larger than the expected ratios of GWAS's power imbalance, especially for diseases whose average risk allele frequencies were low, such as myopia, sudden cardiac arrest, and systemic lupus erythematosus. CONCLUSIONS Minor alleles are more likely to be risk alleles in the published GWASs on complex diseases. One reason is that minor alleles are more easily detected as risk alleles in GWASs. Even when correcting for the GWAS's power imbalance, minor alleles are more likely to be risk alleles, especially in some diseases whose average risk allele frequencies are low. These analyses serve as a starting point for future studies on quantifying the degree of negative natural selection in various complex diseases.

Abstract
INTRODUCTION Development of evidence-based medicine has made a big change in diagnosis and treatment of chronic low back pain. The recent trend is assessed through a review of literature. METHODS The articles published in these 10 years are reviewed, and important points are examined. RESULTS In diagnosis, challenges for history taking and limit of imaging or clinical guidelines are revealed. In treatment, cognitive behavioral treatment and exercises are proved effective. Sleep disturbance has recently attracted attention as a factor associated with low back pain. Cost-effectiveness of diagnosis and treatment modalities has come to be emphasized. CONCLUSIONS Diagnosis and treatment of chronic low back pain have been significantly changing. Multidisciplinary and multidimensional approach is essential. Chronic low back pain should be treated as a total pain, not a local pain.

Abstract
Background: Traction apophysitis of medial epicondyle (MEC) lesions and osteochondritis dissecans (OCD) of the capitellum are common elbow injuries in adolescent baseball players. However, the age-specific prevalence of these pathologies and their influence on elbow pain remain unknown. Purpose: To investigate the age-specific prevalence of each MEC lesion and capitellar OCD and to identify the incidence of elbow pain in each condition. Study Design: Descriptive epidemiology study. Methods: Study participants consisted of 4249 baseball players aged 6 to 17 years. A questionnaire was used to assess history of elbow pain, and morphological changes of the elbow joint were assessed using ultrasonography. Results: Regarding MEC lesions, fragmented (FG) and irregular (IR) lesions both reached their greatest respective prevalence at 11 to 12 years of age. After 14 years of age, IR decreased sharply, whereas FG was maintained at approximately 10%. Hypertrophic (HT) lesions increased sharply, reaching over 50% at 16 years of age, while there was a decrease in IR and FG lesions in the same age group. The prevalence of capitellar OCD remained the same (approximately 2%) throughout all ages except for in players aged 7 to 8 years (>7%). Players with MEC lesions had significantly greater prevalence of a history of elbow pain compared with those without (68.0% vs 39.1%) and were at a significantly greater risk for FG lesions (odds ratio [OR], 4.04; 95% CI, 3.16-5.22) compared with IR (OR, 3.22; 95% CI, 2.44-4.27) and HT lesions (OR, 2.03; 95% CI, 1.75-2.36). Players with capitellar OCD also had a significantly greater risk of a history of elbow pain (OR, 2.34; 95% CI, 1.40-4.11). Conclusion: Controlling the amount of practice and its intensity according to the condition of each player in the preadolescent and adolescent periods may be important in accelerating bony healing and decreasing preventable elbow pain in adulthood.

Abstract
PURPOSE Pelvic vascular injury is a serious complication associated with acetabular component setting with screw fixation in cementless total hip arthroplasty (THA). In this study, we investigated the safety zone for acetabular component setting with screw fixation in cementless THA as a means to prevent pelvic vascular injury. METHODS Thirty left hip joints of Japanese cadavers (11 males and 19 females) were analyzed. We used a hemispherical measuring cup with 52 guide holes designed to allow vertical insertion of a Kirschner wire. After the measuring cup was placed on the acetabulum, the Kirschner wire was inserted from each guide hole to examine the anatomical relationship between the acetabulum and the pelvic vessels. We calculated the frequency of pelvic vessel punctures and measured the distance from the acetabular surface to the pelvic vessels at each guide hole. RESULTS Our findings revealed that pelvic vessels do not exist in certain parts of the posterior area of the acetabulum. Furthermore, in this area, intrapelvic vessels are either lacking or located at a distance ≥31 mm from the surface of the acetabulum. CONCLUSION The posterior area of the acetabulum, excluding its central portion, appeared to be the safety zone for acetabular screw fixation in Japanese cadavers.

Abstract
UNLABELLED Residual cholesteatoma revealed by endoscopy after microsurgery. OBJECTIVE To endoscopically examine common sites of residual cholesteatoma occurrence after microscopic ear surgery. METHODS Thirty patients (15 men and 15 women; age range: 7-81 years) who underwent treatment for middle ear cholesteatoma (20 patients with pars flaccida :holesteatoma and 10 patients with pars tensa cholesteatoma) were selected. Following the removal of the cholesteatoma matrix via microscopy, residual matrix presence was assessed using an endoscope system. Additional resection was performed if the residual matrix was detected. Sites of residual matrix and their rates of incidence were then investigated. RESULTS Residual matrix was observed in nine out of the 30 (30%) patients by endoscopy after microscopic surgery. Residual matrix was observed in eight out of the 20 (40%) patients with pars flaccida cholesteatoma and in one out of :he 10 (10%) patients with pars tensa cholesteatoma. Residual matrix was observed in six out of the 14 (43%) patients who underwent canal wall up (CWU) tympanomastoidectomy and in three out of the 13 (23%) patients who underwent -anal wall down (CWD) tympanomastoidectomy. Sites of residual matrix included the tegmen tympani in two patients, he medial scutal surface in three patients, the tympanic sinus in two patients and the anterior epitympanic recess in three patients. The risk of residual matrix was greater in patients with pars flaccida cholesteatoma than in those with pars tensa :holesteatoma. The attic, tympanic sinus and anterior epitympanic recess are common sites of residual cholesteatoma. CONCLUSION Endoscopy is advantageous for the assessment of residual cholesteatoma in hidden areas.
