The relationship between frailty and spinal alignment in the elderly general population: a two-year longitudinal study.

PURPOSE: Frailty is caused by age-related decline in physical function, which may contribute to worsening spinal alignment. Cardiovascular Health Study (CHS)-criteria for assessing physical function seem more appropriate than frailty index which evaluate comorbiduty. However, there have been no reports investigating the relationship between frailty and spinal alignment using the CHS criteria. This study aimed to examine spinal radiographic parameters using the CHS criteria in volunteers participating in a health screening study. METHODS: The subjects were 211 volunteers (71 males and 140 females) aged 60-89 years old who participated in the TOEI study in 2018 and 2020. They were divided into three groups (R: robust, PF: pre-frailty, and F: frailty) according to the score of the Japanese version of the CHS (J-CHS) criteria in 2018. The radiographic parameters were evaluated using a whole-spine standing X-ray. RESULTS: There were 67 volunteers in group R, 124 volunteers in group PF, and 20 volunteers in group F. Of the five items in the J-CHS criteria, low activity was the most common in the PF group (64%). Low activity was also the most common in the F group (100%). Regarding spinal alignment, significant differences were found in C7SVA in 2020 (R:PF:F = 26:31:62 mm, P = 0.047), C2SVA in 2018 (20:34:63 mm, P = 0.019), and C2SVA in 2020 (37:47:78 mm, P = 0.041). CONCLUSION: Frailty was associated with a worsening in global alignment along the 2- year follow up. The frailty may begin with a decrease in activity and progression of exhaustion; preventing this progression is important through motivation to exercise. LEVEL OF EVIDENCE: II.

Association between the 25-question Geriatric Locomotive Function Scale score and the incidence of certified need of care in the long-term care insurance system: The TOEI study.

BACKGROUND: The Geriatric Locomotive Function Scale is a screening tool to identify the risk of locomotive syndrome in the elderly. We aimed to clarify the association of Geriatric Locomotive Function Scale scores with the incidence of certified need of care in the long-term care insurance system in a prospective longitudinal observational study (the TOEI Study). METHODS: Participants were individuals aged ≥50 years from a mountainous area who had undergone medical check-ups by the National Health Insurance in Toei. The Geriatric Locomotive Function Scale questionnaire, physical performance tests, and radiographs were completed by participants. The primary endpoint was the incidence of certified need of care in the long-term care insurance system. The secondary endpoint was the incidence of either one of the following events: certified need of care or death. RESULTS: We enrolled 681 subjects (271 men and 410 women). The mean age was 72.9 (range, 50-92) years. The incidences of certified need of care and either one of the two events were 104 and 130, respectively, during the average 4.9-year follow-up. The cumulative incidence rates of certified need of care by groups of the Geriatric Locomotive Function Scale, namely, Group 0 (score 0-6), Group 1 (score 7-15), and Group 2 (score 16-) were 7.5%, 14%, and 35%, respectively. The cumulative incidence rates of either one of the two events by group were 11%, 18%, and 39%, respectively. There was a significant association between higher Geriatric Locomotive Function Scale scores and survival rates (not achieved at each endpoint) for the primary and secondary endpoints. CONCLUSIONS: Higher Geriatric Locomotive Function Scale score was associated with greater incidence of certified need of care in the long-term care insurance system as well as either one of the two aforementioned events. This scale might enable prediction of prognosis among elderly patients.

Deterioration of sagittal spinal alignment with age originates from the pelvis not the lumbar spine: a 4-year longitudinal cohort study.

PURPOSE: There is controversy regarding age-related deterioration of spinal sagittal alignment in cross-sectional study. Although we reported that deterioration in spinal alignment originated at the cervical spine in males and the pelvis in females, others studies have indicated that the lumbar spine is initially implicated in both sexes. The purpose of this study was to clarify these differences in a longitudinal cohort study. METHODS: Our analysis was based on 237 individuals aged 60-89 years who participated in our health screening study in 2014 and 2018. They were classified into six groups by birth year and sex: 60-69 years (26 males, 49 females); 70-79 years (35 males, 88 females); and 80-89 years (19 males, 20 females). The following parameters were measured from standing radiographs: pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis, T1 slope, cervical lordosis, C7 sagittal vertical axis (C7 SVA), and C2-7 SVA. RESULTS: In males, the first significant change was an increase in the PT angle (19°, in 2014, to 21°, in 2018) in the 80-89 years age group (P < 0.05), with no significant deterioration in cervical parameters. In females, spinal deterioration included a change in the SS (32°-30°), PT (18°-20°), and SVA (- 8 to 6 mm) in the 60-69 years age group (P < 0.05), with no change in the LL. CONCLUSIONS: Contrary to prior studies, our longitudinal data indicated that deterioration in spinal alignment originates in the pelvis for both sex but develops earlier in females than males.

Implications of the diagnosis of locomotive syndrome stage 3 for long-term care.

Objectives: Locomotive syndrome stage 3 (LS3), which has been established recently, may imply a greater need for care than LS stage 0 (LS0), LS stage 1 (LS1), and LS stage 2 (LS2). The relationship between LS3 and long-term care in Japan is unclear. Therefore, this study aimed to examine this relationship. Methods: A total of 531 patients (314 women and 217 men; mean age, 75 years) who were not classified as requiring long-term care and underwent musculoskeletal examinations in 2012 were grouped according to their LS stage. Group L comprised patients with LS3 and Group N comprised those with LS0, LS1, and LS2. We compared these groups according to their epidemiology results and long-term care requirements from 2013 to 2018. Results: Fifty-nine patients (11.1%) were diagnosed with LS3. Group L comprised more patients (50.8%) who required long-term care than Group N (17.8%) (P < 0.001). Group L also comprised more patients with vertebral fractures and knee osteoarthritis than Group N (33.9% vs 19.5% [P = 0.011] and 78% vs 56.4% [P < 0.001], respectively). A Cox proportional hazards model and Kaplan-Meier analysis revealed a significant difference in the need for nursing care between Groups L and N (log-rank test, P < 0.001; hazard ratio, 2.236; 95% confidence interval, 1.451-3.447). Conclusions: Between 2012 and 2018, 50% of patients with LS3 required nursing care. Therefore, LS3 is a high-risk condition that necessitates interventions. Approaches to vertebral fractures and osteoarthritis of the knee could be key.

Prospective nursing care certification using the 25-question Geriatric Locomotive Function Scale.

AIM: The 25-question Geriatric Locomotive Function Scale (hereafter, "GLFS-25") is a simple screening tool to detect elderly individuals at high risk of locomotive syndrome and promote interventions. This cohort study aimed to clarify if it can predict the need for nursing care certification in the near future. METHODS: Participants were 531 Japanese adults aged ≥65 years who had undergone a healthcare checkup in 2012 and never received nursing care certification until 2012. We collected baseline information and conducted a physical examination in 2012. We investigated the presence of nursing care certification and care need level from 2013 to 2018. Relationships of these factors with nursing care certification after 6 years were assessed. A receiver operating characteristic curve for both the GLFS-25 and physical examination were used to determine optimal threshold value. RESULTS: From 2013 to 2018, 114 volunteers (21.4%) applied for nursing care certification and 29 volunteers died. The group with nursing care certification (over support level 1) had an average age of 79.9 years and a mean score of 17.8 on the scale. Those without nursing care certification had an average age of 74.1 years and a mean score of 8.7. When the GLFS-25 score was 12.5, sensitivity was 0.658 and specificity was 0.760. The area under the curve was 0.736 (95% confidence interval 0.682-0.789). CONCLUSIONS: The GLFS-25 has enabled early detection of individuals with locomotive syndrome who are more likely to need nursing care certification in the near future. We propose using a cutoff score of 13 for the scale. Geriatr Gerontol Int 2021; 21: 492-497.

Relationship between locomotive syndrome, frailty and sarcopenia: Locomotive syndrome overlapped in the majority of frailty and sarcopenia patients.

AIM: The relationship between locomotive syndrome (LS), frailty and sarcopenia is unclear. This cohort study investigates the epidemiology of the three conditions and examines the relationship between them. METHODS: The participants were 337 Japanese adults aged ≥60 years who had undergone a healthcare checkup. LS, frailty and sarcopenia were assessed using the Geriatric Locomotive Function Scale, the Kihon Checklist and the Asian Working Group for Sarcopenia criteria, respectively. The epidemiological investigation and correlations of the three concepts were examined. RESULTS: In total, 212 participants (63%) were women. The participants' mean age was 76 years (range 60-94 years). The average Geriatric Locomotive Function Scale total score was 11.4 ± 11.2, and Kihon Checklist was 4.72 ± 3.97. A total of 202 (59.9%) participants met one of the criteria; 190 (56.9%) were diagnosed with LS, 77 (22.6%) with frailty and 26 (7.7%) with sarcopenia; and 70 out of 77 (90.1%) of frailty patients and 21 out of 26 (80.1%) of sarcopenia patients were included in LS. The relationship between the total score, subcategorical scores and survey items for each was investigated. Activities of daily living, physical function and mental status showed a strong correlation with all concepts. However, nutrition of frailty patients and muscle mass of sarcopenia patients did not correlate with other factors. CONCLUSIONS: LS overlapped with frailty and sarcopenia. LS criteria might be useful as the best tool to screen older persons who would be at risk for requiring care in the near future. However, nutrition status could only be assessed by frailty and muscle mass by sarcopenia. Geriatr Gerontol Int 2021; 21: 458-464.

Spinal Sagittal Alignment, Hospital Anxiety and Depression Scale Scores, and Patient-Reported Outcome among People with Sporting Activity.

STUDY DESIGN: Retrospective cohort study. PURPOSE: This study aimed to investigate how participation in sporting activity affects patient-reported outcome (PRO), including Neck Disability Index (NDI), in males and females. OVERVIEW OF LITERATURE: Previously, our study reported that factors with a negative influence on the NDI in females were a lack of sporting activities. However, it was still unclear why it affected poor scores of NDI. METHODS: The subjects were 473 volunteers. They were divided into two groups (activity and non-activity) according to participation or non-participation in sporting activities using a self-filled questionnaire. The evaluation items were height, weight, grip strength, bone density, Hospital Anxiety and Depression Scale (HADS) score, standing radiographic parameters, PRO (evaluated by EuroQol-5 dimension [EQ-5D], Oswestry Disability Index [ODI]), and NDI. RESULTS: There were 101 males in the non-activity group and 69 in the activity group and 178 females in the non-activity group and 125 in the activity group. For the males, the evaluation items with significant influence were cervical lordosis (non-activity group:activity group, 17°:22°) and T1 slope minus cervical lordosis (10°:6°, p <0.05). For the females, the evaluation items with significant influence were sagittal vertical axis (28:14 mm), HADS (10.4:8.4), EQ-5D (0.79:0.86), ODI (17:12), and NDI (12:9, p <0.01). HADS and PRO in the females were significantly correlated with the EQ-5D (-0.40), ODI (0.43), and NDI (0.55). CONCLUSIONS: Males who participated in sporting activities had better cervical spine alignment but no effect on PRO. Females with sporting activities had better spinal global alignment and less mental stress. It is suggested that sporting activity in females might be associated with PRO because HADS highly correlates with PRO.

Possible enhancement of BP180 autoantibody production by herpes zoster.

Bullous pemphigoid (BP) is an autoimmune blistering disease caused by autoantibodies against type XVII collagen/BP180 (BP180). Although the mechanisms of autoantibody production remain to be elucidated, herpes virus infections have been identified as a possible triggering factor for pemphigus. We report a case of herpes zoster (HZ) having anti-BP180 serum antibodies. The patient developed sudden-onset, tense blisters and edematous erythema on the right anterior chest, shoulder and upper back. Histopathology showed remarkable degeneration of keratinocytes, acantholysis and blister formation with ballooning cells, indicating herpes virus infection. A polymerase chain reaction analysis of varicella zoster virus (VZV) was positive in crusts and effusions from the skin lesions, confirming the definitive diagnosis of HZ. Notably, we found that the patient had anti-BP180 serum antibodies in association with the occurrence of HZ. After successful treatment with valacyclovir hydrochloride for 7 days, the serum levels of anti-BP180 antibodies decreased in accordance with the improvement of skin lesions. These findings suggest that the production of anti-BP180 antibodies could be triggered by the reactivation of VZV.
