Factors associated with work sustainability in patients with bone metastasis.

BACKGROUND: Working while receiving cancer treatment is challenging for patients, with considerable impact on their quality of life (QOL). However, there have been no reports on the factors that prevent employment in patients with bone metastases. This study aimed to investigate the employment status and factors impacting the continued employment of patients with bone metastases. METHODS: We analyzed clinical data from new patients consulting The University of Tokyo Hospital team for bone metastasis treatment between June 2015 and September 2017. Patients who were working at the time of cancer diagnosis (n = 124) completed four QOL questionnaires. Factors associated with work sustainability were identified via univariate analysis and a chi-squared test. Multivariate logistic regression analysis was used for significant variables. Relationships between employment and QOL scales were investigated using the Wilcoxon rank-sum test, with P < .05 considered as statistically significant. RESULTS: Among the 124 patients, only 45 (36.3%) were still working when the questionnaire was administered. Multivariate analysis revealed temporary employment, lytic or mixed bone metastases, and lower limb or acetabular metastasis, as significant factors hindering work sustainability. The QOL scores were high in the continued employment group. However, the relationship between employment status and pain remains unclear. CONCLUSIONS: Lytic or mixed bone metastases and the lower limb and acetabular metastasis were significantly associated with employment resignation. Mobility difficulties may prevent patients with bone metastases from sustaining employment. Collaboration between rehabilitation professionals, oncologists, and workplaces is imperative to address this problem.

End-of-life walking ability in cancer patients with spinal metastases.

BACKGROUND: Even terminal cancer patients desire to walk to the toilet by themselves until the very last day. This study aimed to describe the walking ability of patients with spinal metastases at the end-of-life stage and identify the factors affecting this ability. METHODS: Among 527 patients who first visited our multidisciplinary team for bone metastasis between 2013 and 2016, 56 patients who had spinal metastases with a Spinal Instability Neoplastic Score ≥7 and died during follow-up were included. We collected general clinical data, performance status, Frankel classification, epidural spinal cord compression scale and Spinal Instability Neoplastic Score at the first consultation. Patients' last day of walking and date of death were also examined. Univariate analyses (chi-squared tests) were performed to identify the factors that impacted walking ability 30 and 14 days before patients' death. RESULTS: A total of 56 patients were extracted, and 57.1% (32/56) and 32.7% (16/49) of patients were ambulatory 30 and 14 days before death, respectively. Their performance status (P = 0.0007), Frankel grade (P = 0.012) and epidural spinal cord compression grade (P = 0.006) at the first examination, and administration of bone modifying agents during follow-up period (P = 0.029) were significantly related to walking ability 30 days before death. Among ambulatory patients 30 days before death, those with Spinal Instability Neoplastic Score ≥10 (P = 0.005), especially with high scores of collapse (P = 0.002) and alignment (P = 0.002), were less likely to walk 14 days before death. The walking period in the last month of their life was significantly longer in patients with total Spinal Instability Neoplastic Score 7-9 (P = 0.009) and in patients without collapse (P = 0.040) by the Wilcoxon test. CONCLUSION: The progression of spinal metastasis, especially neurological deficit, at the initial consultation were associated with walking ability 30 days before death, and spinal stability might be crucial for preserving walking ability during the last month. Early diagnosis and implementation of appropriate bone management might be important for the end-of-life walking ability.

Most Fractures Treated Nonoperatively in Individuals With Fibrodysplasia Ossificans Progressiva Heal With a Paucity of Flareups, Heterotopic Ossification, and Loss of Mobility.

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is an ultrarare genetic disorder with episodic and progressive heterotopic ossification. Tissue trauma is a major risk factor for flareups, heterotopic ossification (HO), and loss of mobility in patients with FOP. The International Clinical Council on FOP generally recommends avoiding surgery in patients with FOP unless the situation is life-threatening, because soft tissue injury can trigger an FOP flareup. Surprisingly little is known about flareups, HO formation, and loss of mobility after fractures of the normotopic (occurring in the normal place, distinct from heterotopic) skeleton when treated nonoperatively in patients with FOP. QUESTIONS/PURPOSES: (1) What proportion of fractures had radiographic evidence of union (defined as radiographic evidence of healing at 6 weeks) or nonunion (defined as the radiographic absence of a bridging callus at 3 years after the fracture)? (2) What proportion of patients had clinical symptoms of an FOP flareup because of the fracture (defined by increased pain or swelling at the fracture site within several days after closed immobilization)? (3) What proportion of patients with fractures had radiographic evidence of HO? (4) What proportion of patients lost movement after a fracture? METHODS: We retrospectively identified 36 patients with FOP from five continents who sustained 48 fractures of the normotopic skeleton from January 2001 to February 2021, who were treated nonoperatively, and who were followed for a minimum of 18 months after the fracture and for as long as 20 years, depending on when they sustained their fracture during the study period. Five patients (seven fractures) were excluded from the analysis to minimize cotreatment bias because these patients were enrolled in palovarotene clinical trials (NCT02190747 and NCT03312634) at the time of their fractures. Thus, we analyzed 31 patients (13 male, 18 female, median age 22 years, range 5 to 57 years) who sustained 41 fractures of the normotopic skeleton that were treated nonoperatively. Patients were analyzed at a median follow-up of 6 years (range 18 months to 20 years), and none was lost to follow-up. Clinical records for each patient were reviewed by the referring physician-author and the following data for each fracture were recorded: biological sex, ACVR1 gene pathogenic variant, age at the time of fracture, fracture mechanism, fracture location, initial treatment modality, prednisone use at the time of the fracture as indicated in the FOP Treatment Guidelines for flare prevention (2 mg/kg once daily for 4 days), patient-reported flareups (episodic inflammatory lesions of muscle and deep soft connective tissue characterized variably by swelling, escalating pain, stiffness, and immobility) after the fracture, follow-up radiographs of the fracture if available, HO formation (yes or no) as a result of the fracture determined at a minimum of 6 weeks after the fracture, and patient-reported loss of motion at least 6 months after and as long as 20 years after the fracture. Postfracture radiographs were available in 76% (31 of 41) of fractures in 25 patients and were independently reviewed by the referring physician-author and senior author for radiographic criteria of fracture healing and HO. RESULTS: Radiographic healing was noted in 97% (30 of 31) of fractures at 6 weeks after the incident fracture. Painless nonunion was noted in one patient who sustained a displaced patellar fracture and HO. In seven percent (three of 41) of fractures, patients reported increased pain or swelling at or near the fracture site within several days after fracture immobilization that likely indicated a site-specific FOP flareup. The same three patients reported a residual loss of motion 1 year after the fracture compared with their prefracture status. HO developed in 10% (three of 31) of the fractures for which follow-up radiographs were available. Patient-reported loss of motion occurred in 10% (four of 41) of fractures. Two of the four patients reported noticeable loss of motion and the other two patients reported that the joint was completely immobile (ankylosis). CONCLUSION: Most fractures treated nonoperatively in individuals with FOP healed with few flareups, little or no HO, and preservation of mobility, suggesting an uncoupling of fracture repair and HO, which are two inflammation-induced processes of endochondral ossification. These findings underscore the importance of considering nonoperative treatment for fractures in individuals with FOP. Physicians who treat fractures in patients with FOP should consult with a member of the International Clinical Council listed in the FOP Treatment Guidelines ( https://www.iccfop.org ). LEVEL OF EVIDENCE: Level IV, therapeutic study.

Impact of the coronavirus pandemic on families of patients with congenital insensitivity to pain with anhidrosis.

BACKGROUND: Novel coronavirus disease (COVID-19) outbreaks have dramatically changed lifestyles, with various effects on the physical and mental health of families and children with various childhood-onset neurological diseases. A questionnaire survey was conducted to identify family-specific issues and needs of patients with congenital insensitivity to pain with anhidrosis (CIPA) during major changes in their daily lives due to the COVID-19 outbreaks. METHODS: An anonymous questionnaire was sent to 56 families that were members of the Association of Patients and Families of CIPA in Japan between October and November 2020, the first 2 months of the third outbreak. RESULTS: Thirty-eight families (67.2% response rate) responded to the questionnaire. The current concerns of the parents were (1) difficulty in predicting the future (19 parents, 50%), (2) household and work concerns (eight parents, 21.1%), and (3) whether they would become infected (25 parents, 65.8%). Fifteen families indicated stress due to increased time together (stress + group), and 10 families had a better understanding of each other due to increased time together. New sleep disturbances and behavioral changes were observed in approximately 20% and 50% of patients with CIPA, respectively. No single factor could explain family stress. There were also free descriptions of the importance of peer support, connections with experts, and prompt responses for resolution. CONCLUSIONS: Each family has its own way of coping with multiple factors that contribute to the stress of the patient and family. A long-established resilience to the disease proved effective during this pandemic.

Longitudinal Analysis of Dysphagia and Factors Related to Postoperative Pneumonia in Patients Undergoing Esophagectomy for Esophageal Cancer.

Few studies have quantified longitudinal changes in swallowing in patients undergoing esophagectomy for esophageal cancer. This study longitudinally analyzed the changes in the Modified Barium Swallow Study Impairment Profile (MBSImP™) scores, swallowing kinematic measurements, and swallowing-related symptoms in patients undergoing esophagectomy. We also examined the association between identified swallowing impairment and aspiration pneumonia after surgery. We included consecutive patients who underwent esophagectomy and completed laryngoscopy and videofluoroscopy before, two weeks, and three months after surgery. We analyzed physiological impairments using the MBSImP. We also assessed the swallowing kinematics on a 5 mL thickened liquid bolus at three time points. Vocal fold mobility was assessed using a laryngoscope. Repeated measures were statistically examined for longitudinal changes in swallowing function. The association between the significant changes identified after esophagectomy and aspiration pneumonia was tested. Twenty-nine patients were included in this study. Preoperative swallowing function was intact in all participants. The timing of swallowing initiation and opening of the pharyngoesophageal segment remained unchanged after surgery. Tongue base retraction and pharyngeal constriction ratio worsened two weeks after surgery but returned to baseline levels three months after surgery. Three months after surgery, hyoid displacement and vocal fold immobility did not fully recover. Aspiration pneumonia occurred in nine patients after surgery and was associated with postoperative MBSImP pharyngeal residue scores. Decreased hyoid displacement and vocal fold immobility were observed postoperatively and persisted for a long time. The postoperative pharyngeal residue was associated with pneumonia and thus should be appropriately managed after surgery.

Body knowledge in children with spina bifida.

BACKGROUND: Patients with spina bifida suffer from motor paralysis and sensory disturbance, secondary deformation of the lower extremities, and development of decubitus ulcers. A deep understanding of one's body, such as identifying the names, functions, relationships, homology (e.g. upper and lower limbs) and relative position of body parts, may prevent secondary disorders. The awareness of the body and its characteristics in children with spina bifida has not been fully elucidated. This study aimed to investigate how children with spina bifida perceive their bodies, especially their paralyzed parts and related or homologous ones. METHODS: Participants included 36 children with spina bifida and 14 control children, aged 5-11 years. They were asked to draw self-portraits, and to answer questions about the names of body parts. The number of drawn body parts in the pictures and the correct response rates to the questions were quantified and compared between children with spina bifida and control children. RESULTS: Children with spina bifida drew fewer hands, legs, and feet than control children. In the verbal tests, children with spina bifida had a lower correct response rate than control children on questions concerning the upper limbs, hands, trunk, and feet. CONCLUSIONS: Children with spina bifida have diminished visuospatial and lexical-semantic body knowledge of the paralyzed parts and related organs.

Visual attention to their own paralytic limbs in children with spina bifida: Measurement of gaze direction using eye tracking.

BACKGROUND: Patients with spina bifida experience sensory and motor paralysis and complications in the form of deformation and skin problems of the lower limbs. Enhancing their awareness of the paralysed lesions could be helpful for these patients to prevent secondary disorders. This study sought to investigate to what extent children with spina bifida are visually aware of their body parts and, in particular, to their paralysed lesions. METHODS: Participants included children with spina bifida (n = 10) and typically developing control children (n = 10) between the ages of 5 and 11 years. All participants were shown still images of themselves on a monitor after which their gaze direction was measured using an eye tracker, with or without providing an instruction to direct their attention to their limbs. The gaze direction data were analyzed and compared between children with spina bifida and the control children. RESULTS: Children with spina bifida paid visual attention to their bodies in a manner similar to that of control children. Prompts to direct their attention to their limbs were effective in both groups; however, the degree of efficacy in children with spina bifida was inferior to that in control children. CONCLUSIONS: Promotion of visual awareness to their paralytic parts could be a reasonable and effective method for children with spina bifida to improve their understanding and recognition of their body and prevent associated skin problems.

Predictive Factors for Oral Intake Recovery After Acute Stroke: Analysis of a Japanese Nationwide Inpatient Database.

OBJECTIVE: It remains unclear which factors contribute to dysphagia recovery after an acute stroke. This study aimed to identify factors associated with complete oral intake recovery in patients with post-stroke dysphagia. METHODS: Data were obtained from the Diagnosis Procedure Combination database, which is a nationwide database of administrative claims and discharge abstracts in Japan. We selected patients admitted within 3 days of stroke onset and conducted multivariable logistic regression analysis. Total oral intake within 30 days of admission was the primary outcome measure. RESULTS: A total of 151,302 patients were included, and total oral intake was observed in 48% of them within 30 days of admission. Total oral intake was significantly associated with age, sex, stroke subtype, consciousness disturbance, low body mass index, multiple comorbidities, and the modified Rankin Scale before stroke onset. In addition, males had worse outcomes than females (odds ratio, 0.75; 95% confidence interval, 0.73-0.77, p < 0.001), and intracerebral and subarachnoid hemorrhagic stroke subtypes were associated with non-recovery. CONCLUSION: This study identified several prognostic factors for total oral intake in patients with acute stroke. These results may be useful for predicting a patient's dysphagia prognosis at the time of admission and designing a nutritional management plan for patients with acute stroke.

Treatment approaches for congenital transverse limb deficiency: Data analysis from an epidemiological national survey in Japan.

BACKGROUND: Congenital limb deficiency is a rare anomaly that impairs limb function. Transverse deficiency accounts for approximately half of congenital limb deficiency cases. In Japan, there have been no detailed data of clinical features, especially treatment approaches, of this disorder. The present study aimed to investigate the status of treatment approaches of congenital transverse limb deficiency in Japan. METHODS: From the national epidemiological survey of congenital limb deficiency undertaken in Japan in 2016, all the data of 200 patients with congenital transverse limb deficiencies were extracted. These data were analysed to reveal the treatment approaches of congenital transverse limb deficiency and its basic clinical features. RESULTS: Surgical treatments and prosthetic or orthotic intervention had been implemented or planned for about one-quarter of patients, respectively. In the upper limb deficiencies, prosthetic or orthotic intervention was likely chosen in cases of deficiency at the metacarpal or proximal to metacarpal level. Surgical treatment was chosen only in cases of deficiency at the carpal or distal to carpal level. Although the number of patients with transverse lower limb deficiencies was small, prosthetic or orthotic intervention was likely chosen in proximal deficiencies, and surgical treatment was likely chosen in distal deficiencies. CONCLUSIONS: Herein, we revealed the status of treatment approaches for congenital transverse limb deficiency in Japan. Approximately half of the patients had no history of-and no plans for-surgical, prosthetic, or orthotic interventions. Further treatment advances may enable patients with congenital limb deficiencies to increase their participation in daily activities. STUDY DESIGN: Cross-sectional survey.

Predictive factors of the 30-day mortality after surgery for spinal metastasis: Analysis of a nationwide database.

BACKGROUND: Surgical procedure for symptomatic spinal metastasis is expected to improve the quality of life. Factors related to short-term perioperative mortality after surgery for spinal metastasis may be different from those related to long-term mortality, which have classically been used to determine the indication for surgery. The purposes of this study were to evaluate factors related to the 30-day mortality after surgery for spinal metastasis and create an integer risk scoring system. METHODS: Using the Diagnosis Procedure Combination database from 2010 to 2016, we extracted data of patients who underwent surgical procedure for spinal metastasis. Multivariable logistic regression analysis was performed to clarify the association between patient backgrounds and the 30-day postoperative mortality. We created a risk scoring system using regression coefficients to estimate the 30-day mortality for each patient. RESULTS: Among 3524 patients, the 30-day mortality was 2.6%. Factors associated with a higher 30-day mortality were male sex (odds ratio, 2.50 [95% confidence interval, 1.45-4.31]), emergency admission (1.80 [1.11-2.92]), rapid growth tumors (3.83 [2.49-5.90]), and non-skeletal metastasis (2.27 [1.42-3.64]). In patients with the maximum risk score of five, the 30-day mortality was 16.2%. CONCLUSIONS: Factors related to the 30-day mortality were male sex, emergency admission, rapid growth tumors, and non-skeletal metastasis. These findings provide spine surgeons and patients knowledge of the potential risk of short-term perioperative mortality and allow them to consider the risk of surgery.

Relationship between the physician-based clinical scale for foot and ankle surgery and patient-reported outcomes in patients with long-standing rheumatoid arthritis: Results from a multicenter prospective observational cohort study.

OBJECTIVES: To validate and establish targets for the physician-based clinical scale for foot surgery in rheumatoid arthritis (RA) patients based on patient-reported outcomes from a multicenter prospective cohort. METHODS: We collected data on demographics, values from the RA foot and ankle scale by the Japanese Society for Surgery of the Foot (JSSF-RA), and patient-reported outcomes (PROs) including the Health Assessment Questionnaire Disability Index (HAQ-DI) before (baseline) and 6 and 12 months after joint surgery. Target values for JSSF-RA were determined according to the lower limit of the 95% CI of JSSF-RA in patients with HAQ-DI ≤0.5 after adjusting for age and sex. We used multiple linear regression analysis to examine potential predictors of JSSF-RA target achievement at baseline. RESULTS: Cross-sectional analysis was conducted on data from 417 cases. The JSSF-RA target for foot and ankle surgery was set at 74 according to the JSSF-RA value corresponding to HAQ-DI ≤0.5 (mean 77.6, 95% CI: 74.3-80.9). Longitudinal analysis of patients who underwent foot surgery (N = 59) determined target cut-off values of 1.188 and 65 for HAQ-DI and JSSF-RA at baseline, respectively, as being predictive for achieving JSSF-RA ≥74 after surgery. CONCLUSIONS: A JSSF-RA value of 74 represents an important target for patients with RA who have undergone foot surgery. In order to achieve this target, the timing of the surgery should be considered in the treatment of established RA patients.

Impact of fracture characteristics and disease-specific complications on health-related quality of life in osteogenesis imperfecta.

Osteogenesis imperfecta (OI) is a connective tissue disease with bone fragility. Several studies have indicated that physical function in adult OI was correlated to the disease severity, but there have been no reports delineating the impact of the fracture characteristics and disease-specific complications on health-related quality of life (HRQoL). The purpose of this study is to clarify the factors impacted on HRQoL in adult OI patients. We conducted a cross-sectional study between July 2016 and March 2018 and sent a questionnaire regarding HRQoL using Short Form-36 (SF-36) to the OI patients at the age of 20 years or older who had a medical history of the investigators' institutions. The 40 patients completely answered the SF-36. Mental component summary and role/social component summary were unremarkable. Physical component summary (PCS) was significantly associated with z-score for height, teeth abnormality, and cardiopulmonary insufficiency (partial regression coefficient, 3.04, - 9.70, and - 11.35; p, < 0.001, 0.047, and 0.025, respectively). PCS was also significantly lower in the patients who had an initial fracture before the age of 2 years than those without occurrence of fractures until 2 years old (25.80 ± 17.15 versus 44.20 ± 16.54; p = 0.002), or those who had lower extremity fractures more than five times as compared with normal populations. Physical function was decreased in OI patients who had fractures before 2 years old, especially in lower extremity. Appropriate medical managements for cardiopulmonary insufficiency are required not only to maintain physical function but also to decrease mortality.

Factors associated with health-related quality of life in patients with glioma: impact of symptoms and implications for rehabilitation.

OBJECTIVE: The factors associated with health-related quality of life in patients with glioma remain unclear; particularly, the impact of symptoms on quality of life has not been studied comprehensively. This study aims to document the quality of life of patients with glioma and clarify the impact of symptoms. METHODS: In this cross-sectional study, participants were recruited from patients at The University of Tokyo Hospital and from patients who were registered at the Japan Brain Tumor Alliance. We included adult patients with World Health Organization grade II-IV glioma and excluded those with disturbances of consciousness or aphasia. We used the European Organization for Research and Treatment of Cancer QLQ-C30 and BN20 to evaluate quality of life and the symptoms. Multiple regression analyses were performed to investigate the impact of symptoms on European Organization for Research and Treatment of Cancer global health status and QLQ-C30 social functioning. In addition, we performed univariate subgroup analyses classified by World Health Organization grade and history of chemotherapy. RESULTS: This study included 76 patients. Seven symptoms occurred in more than 50% of the patients: fatigue, future uncertainty, drowsiness, communication deficit, financial difficulties, motor dysfunction and weakness of legs. Multiple regression analyses showed that insomnia affected their global health status, and appetite loss, financial difficulties and motor dysfunction were significantly related to their social functioning. In subgroup analysis, the number of symptom subscales that were significantly related to global health status and social functioning was larger in World Health Organization grade II patients compared with grade III/IV patients. CONCLUSIONS: In addition to neurological deficits, symptoms were associated with poor quality of life in patients with glioma. This study provided the basis on further investigation of usefulness of symptom evaluation on quality of life improvement.

Effect of prostheses on children with congenital upper limb deficiencies.

BACKGROUND: Individual weaknesses in motor skills are a characteristic of children with congenital upper limb deficiencies. These weaknesses increase with age. In Japan, however, prosthetic prescription and subsequent rehabilitation approaches for children with upper limb deficiencies are insufficient and often delayed. This study aimed to elucidate whether rehabilitation approaches, including prostheses prescription and occupational therapy, improve these children's adaptive behaviors, especially their motor skills. METHODS: The study included nine children, aged 0-6 years, with unilateral transradial or transcarpal upper limb deficiencies. We measured their adaptive behaviors and motor skills at the beginning of prosthetic therapy and after 1.5 years, using the Vineland Adaptive Behavior Scales - Second Edition. RESULTS: The score for the motor skills domain was significantly lower than the median score of the domains at the beginning of prosthetic therapy. The motor skill weaknesses significantly improved after 1.5 years of prosthetic therapy. CONCLUSIONS: Although children with congenital upper limb deficiencies have individual weaknesses in their motor skill behavior, it was shown that these weaknesses can be improved through rehabilitation approaches, including occupational and prosthetic therapies. Issuing the appropriate prostheses and implementing the appropriate training to use the prostheses for congenital upper limb deficiencies are reasonable and meaningful interventions to improve quality of life.

Fibrodysplasia ossificans progressiva: Review and research activities in Japan.

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic skeletal disorder manifesting progressive heterotopic ossification (HO) and congenital malformation of the great toes. Since 2007, we have conducted research on FOP. Here, we review the findings on FOP published to date, including the results of our research. Epidemiological studies in Japan have indicated that FOP has nearly the same prevalence in Japan as in the rest of the world. Basic research on its pathoetiology has progressed rapidly since the identification of the causal gene in 2006. Clinical and radiological findings have been thoroughly researched, including early radiological signs, and diagnostic criteria were established, designating FOP as an intractable disease in Japan. In patients with FOP, the progression of HO is associated with numerous disabilities, often manifesting in vicious cycles that can lead to early mortality. Through cross-sectional and short-term longitudinal studies, we have explored patient education, quality of life, and activities of daily living among Japanese patients. The management of FOP requires education of patients and caregivers, the use of medications to settle inflammation and flare-ups, instructions to ensure proper oral care, and other compensatory approaches that aid in rehabilitation. An avoidance of medical intervention, which may cause HO to progress, is also important. The advent of new drugs to prevent HO could have clinical benefit.

Physical, Mental, and Social Problems of Adolescent and Adult Patients with Achondroplasia.

Patients with achondroplasia (ACH) require various medical interventions throughout the lifetime. Survey of health-related quality of life (HRQoL) in adult ACH patients is essential for the evaluation of treatment outcomes performed during childhood such as growth hormone administration and limb lengthening surgeries, but no study focused on the treatment strategy by analyzing HRQoL of ACH patients. The purpose of this study was to assess whether final height impacted on HRQoL and to evaluate what kinds of medical interventions were positively or negatively associated with HRQoL. We included 184 ACH patients (10-67 years old) who were registered in the patients' associations or who had a medical history of the investigators' institutions, and analyzed HRQoL by using Short Form-36 and patient demographics. Physical component summary (PCS) was significantly lower than the standard values in each age, especially in elderly populations, while mental component summary (MCS) was similar to the standard values. Role/social component summary was deteriorated only in elderly populations. The PCS was improved in the patients who had a height of 140 cm or taller (p < 0.001). The PCS and MCS were strongly associated with the past medical history of spine surgeries (p < 0.001 and p = 0.028, respectively). A treatment strategy would be planned to gain a final height of 140 cm or taller during childhood in combination with growth hormone administration and limb lengthening surgeries. Appropriate medical management for neurological complications of adult ACH patients is required to maintain physical and mental function.

Physical activity and its related factors in Japanese people with haemophilia.

INTRODUCTION: In the general population, benefits of physical activity (PA) include improvement of physical function, prevention of lifestyle diseases and improvement of bone mineral content and quality of life. PA is recommended for patients with haemophilia (PwH), especially for those receiving advanced haemostatic treatment. We hypothesised many PwH engage in insufficient PA. AIM: This study aimed to clarify PA levels and the associated factors in Japanese PwH. METHODS: Physical activity was assessed using the International Physical Activity Questionnaire short version, and basic data, activities of daily living (ADLs) and self-efficacy were also collected. RESULTS: A total of 106 questionnaires were completed. The average age of participant was 40.8 years. The median PA was 693.0 metabolic equivalent-min/wk. More than half of the participants (59.4%) were classified into the low activity group. PA showed a significant inverse correlation with age (P = 0.022) and a positive correlation with self-efficacy (P = 0.018). However, PA did not show a significant relationship with haemophilic severity, prophylactic treatment, annual intra-articular bleeding frequency, body mass index and ADL. In PwH receiving guidance in sports, such as activities that are safe to participate in or performing prophylaxis prior to a physical activity, self-efficacy was significantly higher (P = 0.033), ADL was better (P < 0.001), and mean age was younger (P = 0.01) than in those not receiving guidance in sports. CONCLUSION: As for PA level, 60% of the subjects showed low activity. To promote PA in PwH, improvement of self-efficacy and appropriate guidance may be necessary.

Special considerations for clinical trials in fibrodysplasia ossificans progressiva (FOP).

Clinical trials for orphan diseases are critical for developing effective therapies. One such condition, fibrodysplasia ossificans progressiva (FOP; MIM#135100), is characterized by progressive heterotopic ossification (HO) that leads to severe disability. Individuals with FOP are extremely sensitive to even minor traumatic events. There has been substantial recent interest in clinical trials for novel and urgently-needed treatments for FOP. The International Clinical Council on FOP (ICC) was established in 2016 to provide consolidated and coordinated advice on the best practices for clinical care and clinical research for individuals who suffer from FOP. The Clinical Trials Committee of the ICC developed a focused list of key considerations that encompass the specific and unique needs of the FOP community - considerations that are endorsed by the entire ICC. These considerations complement established protocols for developing and executing robust clinical trials by providing a foundation for helping to ensure the safety of subjects with FOP in clinical research trials.

May perioperative ultrasound-guided pelvic floor muscle training promote early recovery of urinary continence after robot-assisted radical prostatectomy?

AIMS: The efficacy of perioperative pelvic floor muscle training (PFMT) for continence recovery after robot-assisted radical prostatectomy (RARP) remains unclear. Visualization of the bladder neck and urethra using transperineal ultrasound (US) may promote self-recognition of urethral closure during PFM contraction. This study aimed to examine whether transperineal US-guided PFMT promotes early recovery of post-RARP incontinence. METHODS: This prospective cohort study included 116 men undergoing RARP. All men were offered to undergo transperineal US-guided PFMT, and 36 men agreed. The protocol consisted of biofeedback PFMT using transperineal US before RARP and 1-month after RARP with verbal instruction of PFMT immediately after urethral catheter removal. The remaining 80 patients received verbal instruction for PFMT alone. Continence recovery was defined as the number of days requiring a small pad (20 g) per day by self-report. RESULTS: No differences were observed in demographic or peri-operative parameters between the two groups except the longer operative time in the US-guided PFMT group. The mean time until continence recovery was significantly shorter in the US-guided PFMT group (75.6 ± 100.0 days) than in the verbal-PFMT group (121.8 ± 132.0 days, P = 0.037). Continence recovery rates within 30 days were 52.8% (19/36) and 35.4% (28/80) in the US-guided PFMT and verbal-PFMT groups, respectively (P = 0.081). US-guided PFMT was associated with better postoperative continence status (adjusted hazard ratio [95% confidence interval]: 0.550 [0.336-0.900], P = 0.017). CONCLUSIONS: The results showed that transperineal US-guided PFMT perioperatively was associated with early recovery of urinary continence after RARP.

Early detection of bone metastases of hepatocellular carcinoma reduces bone fracture and paralysis.

BACKGROUND: With the improvement in survival of hepatocellular carcinoma patients, extrahepatic metastases have become a more frequent complication. Although pathological fractures or paralysis due to bone metastases deteriorate the quality of life of patients, no treatment guideline for bone metastases has been established. This study aimed to clarify the risk factors for these events and the clinical course of patients with bone metastases. METHODS: Out of 783 hepatocellular carcinoma patients treated in our institution between 2009 and 2016, 76 patients with bone metastases were enrolled. They were divided into two groups by the trigger of bone metastases detection. One was those diagnosed by surveillance (surveillance group), and the other was those based on symptom presentation (non-surveillance group). We investigated the clinical features, risk factors for fractures or paralysis and prognostic factors for survival after bone metastases. RESULTS: Baseline characteristics and survival were not significantly different between two groups. Fractures or paralysis occurred in 10 patients (13.2%), and the frequency was significantly higher in the non-surveillance group (20.9%) than the surveillance group (3.0%) in univariate analysis (p = 0.036). The median survival after diagnosis of bone metastases was 11.7 months. Age over 75 years (p = 0.002), hepatitis C-virus etiology (p = 0.007) and Child-Pugh class B/C (p < 0.001) were significantly associated with a shorter survival in multivariate analysis, but fractures or paralysis did not affect the survival. CONCLUSIONS: Early diagnosis through surveillance for hepatocellular carcinoma bone metastases may prevent fractures or paralysis and lead to a better quality of life for these patients.
