OBJECTIVES: We examined whether eldecalcitol (ELD) provided additive bone mineral density (BMD) and bone turnover marker gains in patients undergoing long-term bisphosphonate (BP) usage, especially in osteoporotic individuals exhibiting a poor response to BPs. METHODS: Forty-two post-menopausal patients with primary osteoporosis and low lumbar BMD (L-BMD) and/or bilateral total hip BMD (H-BMD) values receiving long-term BP treatment were prospectively enrolled. Serum bone alkaline phosphatase (BAP) was measured as a bone formation marker and urinary N-terminal telopeptide of type I collagen (NTX) was assessed as a bone resorption marker. L-BMD, H-BMD, and femoral neck BMD (N-BMD) were recorded before, at the commencement of, and during ELD administration. RESULTS: BAP and urinary NTX were significantly decreased by BP therapy prior to ELD. ELD addition further significantly decreased the bone turnover markers (both p < 0.01). The mean L-BMD increase rate was 0.2% (p = 0.81) from 2 to 1 years before ELD administration, −0.7% (p = 0.30) during the year before ELD, and 2.9% (p < 0.01) during 1 year of ELD. Similar findings were observed for the mean increase rate of H-BMD, with values of 0.2% (p = 0.55), −0.7% (p < 0.01), and 1.2% (p < 0.01), respectively. The mean N-BMD increase rate was significantly increased after ELD administration (1.1%, p = 0.03) despite no gains by BP therapy alone. CONCLUSIONS: This study suggests that ELD addition may be useful for osteoporotic patients exhibiting a diminished long-term BP therapy response.

Osteoporosis and Sarcopenia 2019;5(4):122-127
OBJECTIVES:
Increasing bone mineral density (BMD) to reduce fracture risk is a primary goal of osteoporosis treatment. This prospective, observational study evaluates the effects of monthly minodronate (MIN; 50 mg) with or without eldecalcitol (ELD) addition in osteoporosis patients with rheumatoid arthritis (RA) during 18 months.
METHODS:
The cohort was prospectively and randomly split into the MIN monotherapy group (14 cases) and MIN plus ELD group (combination group; 14 cases) due to no reports on the effectiveness and safety of MIN therapy in relation to ELD addition for comparisons of serum tartrate-resistant acid phosphatase (TRACP)-5b, bone alkaline phosphatase (BAP), and BMD of the lumbar 1–4 vertebrae (L-BMD), bilateral total hips (H-BMD; the mean value of the right and left hips), and bilateral femoral necks (FN-BMD) at baseline and at 6, 12, and 18 months of treatment.
RESULTS:
Baseline values were comparable between the groups apart from a tendency for higher TRACP5b in the combination group. Seven of 14 patients in the combination group had received previous bisphosphonate treatment. BAP was significantly more reduced in the monotherapy group at 6 months, with no other remarkable differences for TRACP5b, L-BMD, H-BMD, or FN-BMD during the observation period.
CONCLUSIONS
The above findings suggest that regardless of ELD addition, MIN potentially improves BMD during 18 months in osteoporosis patients with RA.

OBJECTIVES: The aim of this study was to examine the efficacy, safety, and adherence of ibandronate (IBN) treatment with or without vitamin D supplementation for 3 years in Japanese women with postmenopausal osteoporosis. METHODS: This prospective investigation included 27 patients treated with IBN alone (monotherapy group) and 29 patients receiving IBN and alfacalcidol (ALF) (combination group). Bone metabolism and bone mineral density (BMD) were measured before and at 18, 24, 30, and 36 months of therapy. Treatment discontinuation and fracture occurrence were assessed as well. RESULTS: Lumbar 1–4 BMD (L-BMD) was significantly increased in the monotherapy and combination groups by 3.9% and 7.2%, respectively, at 36 months, with significant gains in total hip BMD (H-BMD) of 3.7% and 4.9%, respectively. There were significant differences in L-BMD improvement between the groups at 18, 24, and 30 months (P < 0.05) and at 36 months (P < 0.01). Compared with pretreatment levels, the percentage changes of L-BMD and H-BMD were significant at all time points in the combination group and at all points apart from L-BMD at 36 months in the monotherapy group. In the monotherapy group, 14 patients dropped out during 3 years and 2 vertebral fractures occurred during the first year. In the combination group, 16 cases dropped out during 3 years and 1 nonvertebral fracture was noted during the first year. CONCLUSIONS: Our findings suggest that combination therapy of IBN and vitamin D is superior to monotherapy with regard to L-BMD improvements for 3 years, with both groups showing comparable safety and adherence to treatment.

OBJECTIVES: The aim of this study was to examine the discontinuation and occurrence of fracture during denosumab treatment in Japanese women with primary osteoporosis or rheumatoid arthritis (RA) with osteoporosis. METHODS: This retrospective study included 143 patients with primary osteoporosis and 96 patients with RA and osteoporosis who were treated with denosumab. Treatment discontinuation, fracture occurrence, lumbar spine (L1–4) bone mineral density (LS-BMD), and bilateral total hip BMD (TH-BMD) were examined before and at 1 and 2 years after treatment commencement. RESULTS: In the primary osteoporosis group, 32 cases dropped out and no fractures occurred from 0 to 1 year. Eighteen cases were lost to follow-up and no fractures were noted from 1 to 2 years. In the RA with osteoporosis group, 7 cases dropped out and no fracture occurred from 0 to 1 year. Twenty-one cases were lost to follow-up and 2 nonvertebral fractures were noted from 1 to 2 years. In this group, 13 cases dropped out from 1 to 2 years and 16 cases dropped out during the 2-year study period due to economic reasons. LS-BMD and TH-BMD values increased continuously for 2 years of treatment in both primary osteoporosis and RA with osteoporosis groups. CONCLUSIONS: These results suggest that during denosumab therapy, the discontinuation rate is expected to remain low during 2 years of treatment in primary osteoporotic patients. In RA patients with osteoporosis, however, the discontinuation rate may increase due to economic reasons from 1 to 2 years of therapy.

OBJECTIVES: This is an open labeled and retrospective cohort study which compared the effectiveness and safety of ibandronate (IBN) and minodronate (MIN) combined with eldecalcitol (ELD) in primary osteoporosis of women. METHODS: One hundred and forty-eight primary osteoporotic women were classified into 3 groups; 1) intravenous IBN combined with oral ELD (IBN + ELD group, N = 50; 81.8 ± 6.2 years), 2) oral MIN combined with oral ELD (MIN + ELD group, N = 50; 77.2 ± 6.9 years) and 3) oral ELD alone (ELD group, N = 48; 75.0 ± 8.3 years). For statistical analysis, L-BMD, H-BMD, serum corrected Ca, serum iP, intact-PTH, TRACP-5b, BAP, serum Hcy, eGFR and urine Ca/Cr ratio were measured until 12 months after the start of therapy. RESULTS: L-BMD values increased significantly in both IBN + ELD and MIN + ELD group, however, H-BMD increased significantly in the IBN + ELD group only. TRACP-5b values decreased rapidly during the first 6 months in both IBN + ELD and MIN + ELD group. However, BAP value in the IBN + ELD group decreased more gradually compared with that in the MIN + ELD group. Both serum Ca value and urine Ca/Cr ratio tended to increase, and the eGFR value decreased significantly in each group. CONCLUSIONS: IBN combined with ELD administration can act more effectively to increase BMD compared with MIN combined with ELD administration. Differences of decreasing rate in TRACP-5b and BAP value may lead to differences of increased rate of BMD in the IBN + ELD and MIN + ELD group. Because many cases of osteoporosis are elderly persons associated with chronic kidney disease, monitoring of kidney function and concentration of Ca in blood and urine is essential.

As a bisphosphonate, minodronate (MIN) is one of the strongest inhibitors of bone resorption. However, there have been no reports directly comparing the antiresorptive effects of monthly MIN with those of monthly risedronate (RIS). We enrolled 30 cases of osteoporosis (OP; 16 in the MIN group [mean age: 68.2 years] and 14 in the RIS group [mean age: 68.1 years]) to investigate the early effects of treatment by monthly MIN or RIS over a 4-month period using bone turnover marker values. Only female patients were enrolled to avoid gender bias. Urinary cross-linked N-telopeptide of type I collagen (NTX) before treatment and at 1, 2, and 4 months of therapy, as well as serum bone alkaline phosphatase and alkaline phosphatase before treatment and at 4 months afterwards, were evaluated. All bone turnover marker values were significantly decreased at 4 months in both groups. The changes in urinary NTX at the study end point for RIS and MIN were -30.1% and -63.1%, respectively. From 2 months of treatment, the antiresorptive effects on urinary NTX by MIN were significantly higher than those by RIS, indicating that MIN more immediately and strongly inhibited bone absorption. Thus, monthly MIN seems to suppress bone resorption faster and more strongly than RIS in OP treatment.

INTRODUCTIONAn observational study was carried out to estimate the strength of the relationships among balance, mobility and falls in hemiplegic stroke inpatients. The objective was to examine factors that may aid in the prediction of the likelihood of falls in stroke patients.
METHODSA total of 53 stroke patients (30 male, 23 female) aged 67.0 ± 11.1 years were interviewed regarding their fall history. Physical performance was assessed using the Berg Balance Scale (BBS) and the Functional Independence Measure (FIM) scale. Variables that differed between fallers and non-fallers were identified, and a discriminant function analysis was carried out to determine the combination of variables that effectively predicted fall status.
RESULTSOf the 53 stroke patients, 19 were fallers. Compared with the non-fallers, the fallers scored low on the FIM, and differed with respect to age, time from stroke onset, length of hospital stay, Brunnstrom recovery stage and admission BBS score. Discriminant analysis for predicting falls in stroke patients showed that admission BBS score was significantly related to the likelihood of falls. Moreover, discriminant analysis showed that the use of a significant BBS score to classify fallers and non-fallers had an accuracy of 81.1%. The discriminating criterion between the two groups was a score of 31 points on the BBS.
CONCLUSIONThe results of this study suggest that BBS score is a strong predictor of falls in stroke patients. As balance is closely related to the risk of falls in hospitalised stroke patients, BBS might be useful in the prediction of falls.

An echocardiogram revealed a mobile mass attached to the left coronary cusp of the aortic valve in an 81-year-old woman. The tumor was surgically removed without valve replacement. The tumor was whitish in color, with a sea anemone-like appearance, and it measured 10 mm in maximum dimension. It was histopathologically defined as papillary fibroelastoma (PFE), and the postoperative course was uneventful. Primary cardiac tumors are rare, and the majority are myxomas. However recent advances in noninvasive examination and surgery may increase the detection of PFE, which occurs most frequently on the endocardial surface of the cardiac valve. We report a case of cardiac PFE with a review of the pertinent literature.

Purpose: To determine whether performing a feint in team handball with a wide foot stance leads to a greater knee valgus angle and/or knee valgus moment.Methods: Eight women handball players performed a feint with 4 different foot stances (free and 30%, 40%, and 50% of their body height). Three-dimensional kinematics and ground reaction forces were measured during the feints. Hip abduction angle at first contact, peak vertical ground reaction force, peak knee valgus angle, and peak external knee valgus moment during the first 20% of the feint cycle were compared among the stances at 30%, 40%, and 50% of body height (ANOVA, P<0.05). In the free feint, we investigated intrasubject correlations among foot stance and hip abduction angle at first contact, peak knee valgus angle, and peak external knee valgus moment were then conducted (P<0.05).Results: When performing a feint with foot stances at 40% and 50% of body height, the subjects had significantly greater peak external knee valgus moment. Hip abduction angle at first contact was significantly correlated to peak knee valgus angle and peak external knee valgus moment.Conclusion: Training athletes to avoid wide foot stance and large hip abduction angle may reduce the risk of sustaining noncontact anterior cruciate ligament injuries.

Like the "day hospices" for cancer patients in England, Japanese day care services may be an effective resource for home-based palliative care. A questionnaire survey was done to investigate what medical services are available to cancer patients in existing day care centers in Japan. Methods: In November 2004, the questionnaire was sent to 108 day care centers in Okayama Prefecture, and there were 49 responses. Results: Out of the 49 day care centers, 36 had been used by cancer patients, 28 (56%) of those centers actually had cancer patients attending at the time of survey, and 4 (8%) of those centers provided special programs for cancer patients. The results of the questionnaire showed that day care centers should provide the following services to enhance domiciliary palliative care for cancer patients: 1) medical palliative treatment; 2) medically supervised special day care services, such as bathing; 3) resting periods to meet the client's needs; 4) medical function support therapy, such as stoma-care, parenteral nutrition, and infusion; and 5) psycho-social support for the patients as well as their families. Conclusion: Existing day care centers in Japan could be effective in functioning as day hospices, similar to those that exist in England.
