Abstract
Pancreatic cancer presents a critical health issue characterized by low survival rates. Identifying risk factors in specific populations, such as those with diabetes, is crucial for early detection and improved outcomes. This study aimed to identify risk factors for pancreatic cancer in diabetic patients using a longitudinal cohort from the Shizuoka Kokuho database, spanning April 2012 to September 2021. Diabetic patients were identified and monitored for the onset of pancreatic cancer. Factors analyzed included age, sex, the Elixhauser comorbidity index, and specific comorbidities. Statistical analyses involved univariate and multivariate Cox proportional hazards regression. The study identified 212,775 as diabetic patients and 1755 developed pancreatic cancer during the period. The annual incidence rate of pancreatic cancer in this group was 166.7 cases per 100,000 person-years. The study identified older age, male sex, a history of liver disease, chronic pancreatitis, and pancreatic cystic lesions as significant risk factors for pancreatic cancer in diabetic patients. The study also highlighted the absence of a significant association between diabetes type or diabetic complications and the onset of pancreatic cancer. These findings may aid in the early diagnosis of pancreatic cancer in diabetic patients and may inform revisions in screening practices in diabetic patients.

Abstract
Body mass index (BMI) has been found to have an impact on neurodegenerative diseases such as Parkinson's disease (PD). Several studies suggested that patients with PD have a lower BMI compared with controls. However, some studies indicated the differences between patients and controls as statistically insignificant. We performed this meta-analysis to clarify the relationship between BMI and PD based on the studies published from 1975 to April 2023 in the PubMed, Embase, and Cochrane Library databases. In total, 18 case-control studies met the inclusion criteria for meta-analysis. We found a statistically significant difference in mean BMI between patients with PD and healthy controls {standardized mean difference (SMD) [95% confidence interval (CI)] = -0.36 (-0.43, -0.29), P < 0.05}. Regarding sex, seven studies were included in the meta-analysis for female/male patients with PD. The mean BMI was significantly different between males with PD and healthy males [SMD (95% CI) = -0.34 (-0.47, -0.22), P < 0.05]. Moreover, the mean BMI of females with PD was significantly different from that of corresponding healthy females [SMD (95% CI) = -0.44 (-0.57, -0.30), P < 0.05]. The meta-analysis demonstrates a significantly lower BMI in patients with PD, but no gender differences, when compared with their respective healthy individuals.NEW & NOTEWORTHY The meta-analysis demonstrates a significantly lower body mass index in patients with PD, but no gender differences, when compared with their respective healthy individuals.

Abstract
Objective: To systematically evaluate the effect of aquatic exercise interventions on the improvement of lower-extremity motor function and quality of life in patients with Parkinson's disease. Methods: Two researchers independently searched the literature using the PubMed, Web of Science, Embase, and Cochrane Library databases. The search period was from the establishment of the database to December 2021. The subject heading search included "hydrotherapy," "hydro therapies," "hydro therapeutics," "water therapy," "aquatic exercise therapy," "aquatic therapy," "water-based exercise," "Parkinson," "Parkinson disease," "Parkinson's disease," "Parkinson's syndrome," "primary Parkinsonism," "paralysis agitans," and "randomized controlled trial (RCT)." Result: A total of 698 articles were retrieved from the four databases by searching for subject headings, and 10 RCT articles were finally included. The balance ability of aquatic exercise in patients with Parkinson's disease (weighted mean differences [WMD] = 2.234, 95% CI: 1.112-3.357, Z = 3.9, p < 0.01), walking ability (WMD = -0.911, 95% CI: -1.581 to -0.241, Z = 2.67, p < 0.01), and quality of life (WMD = -5.057, 95% CI: -9.610 to -0.504, Z = 2.18, p = 0.029) were improved, but there was no significant difference in motor function (WMD = -0.328, 95% CI: -1.781 to 1.125, Z = 0.44, p = 0.658). Conclusion: Compared with conventional rehabilitation therapy, aquatic exercise can effectively improve balance, walking ability, and quality of life in patients with Parkinson's disease. However, it had no obvious effect on improving motor function. This study was limited by the number and quality of the included studies, and more high-quality studies are needed to verify this.

Effectiveness of suvorexant versus benzodiazepine receptor agonist sleep drugs in reducing the risk of hip fracture: Findings from a regional population-based cohort study. PLoS One 2023; 18:e0284726. [PMID: 37093840 PMCID: PMC10124872 DOI: 10.1371/journal.pone.0284726] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 04/05/2023] [Indexed: 04/25/2023] Open
Abstract
Sleep drugs are often necessary to treat insomnia in older patients. Benzodiazepine receptor agonists (BZRAs) are primarily used for insomnia in these patients, but there are concerns regarding their association with delirium and bone fractures. Among sleep drugs, orexin receptor antagonists such as suvorexant have a lower risk of delirium than BZRAs, but their effectiveness in preventing hip fractures is unknown. Hip fracture is a life-threatening trauma in advanced-age patients and a social problem. Therefore, we investigated the relationship between suvorexant and hip fracture. The Shizuoka Kokuho Database was used to compare the time to hip fracture in patients who had been newly taking suvorexant and other sleep drugs such as benzodiazepines since November 2014. A proportional hazards model for hip fracture as an outcome was used to estimate the hazard ratio. Propensity scores were estimated using a logistic regression model, and the confounding factors were age, sex, several comorbidities, and each oral medication. The suvorexant group comprised 6860 patients (110 with hip fracture), and the BZRA group (benzodiazepines and Z-drugs) comprised 50,203 patients (1487 with hip fracture). In the matched cohort (6855:6855 patients), 259 and 249 patients in the suvorexant and BZRA group developed hip fractures during the observational period, respectively. The hazard ratio of the suvorexant group compared with the BZRA group was 1.48 (95% confidence interval, 1.20-1.82). In the subgroup analysis, patients in the suvorexant group had a higher risk of hip fracture if they were aged >75 years, had no diabetes, had no neurological disease, had no renal failure, had liver disease, had hypertension, were not taking alpha 1 blockers, and were not taking oral steroids. Among people in the Japanese regional population who use sleep drugs, patients taking suvorexant can be at higher risk of hip fracture than patients taking BZRAs.

Abstract
UNLABELLED Fracture risk was elevated in Parkinson's disease (PD) patients compared with controls in this nationwide study. Among PD patients, the risk of fracture increased linearly with PD severity, whereas no difference in fracture risk was observed according to PD duration. INTRODUCTION Parkinson's disease (PD) is reported to be associated with a high risk of fractures. Several studies found an association between severity and duration of PD and falls or bone mineral density, but those factors have not been considered in most previous research. The aim of this study was to determine the fracture risk in PD patients according to their disease severity and duration. METHODS This population-based, retrospective cohort study used data from the Korean National Health Insurance Service database. The study population included 10,333 patients with prevalent PD and 6,501,464 comparison cohort. Fracture risks according to the prevalence, severity, and duration of PD were evaluated using Cox proportional hazard methods. RESULTS Fracture risk was elevated in PD patients at all sites compared with controls (adjusted hazard ratio [aHR] 1.49, 95% confidence interval [CI] 1.44-1.56 for any fracture). When comparing fracture sites, hip fractures showed the largest risk increase in PD patients (aHR 2.16, 95% CI 1.95-2.38). Among PD patients, the risk of any fracture increased linearly with PD severity and was highest in patients with severe disease (aHR 1.65, 95% CI 1.53-1.79 compared with controls). Meanwhile, no significant association was observed between PD duration and fracture risk. CONCLUSIONS The prevalence of PD was related to an increased risk of fractures in this nationwide study, and PD severity was linearly associated with fracture risk. PD prevalence and severity should be considered when evaluating the risk factors of fracture in clinical practice.

Abstract
Next to Alzheimer's disease, Parkinson's disease constitutes the second most widespread neurological disorder, primarily affecting the older population. Its symptoms are noticeable with advancing age including tremors, postural imbalance, and slow movements, and over time, these symptoms get aggravated, progressing to osteoporosis, osteopenia, and risk of fractures. These symptoms correlate to low bone density and hence weakened bones; thus, vitamin D proves to be an intricate component of the pathogenesis of the disease. Moreover, lower serum concentrations of vitamin D have been found in diseased subjects. Supplementation with vitamin D can retard the aggravation of non-motor as well as motor symptoms of Parkinson's disease that include cognitive improvement along with the decline in risk of fractures. Also, vitamin D is extremely crucial for brain functioning, targeting dopaminergic neurons, and almost the entire functioning of the brain is affected. However, further exploration is required to determine the toxic dose of vitamin D in Parkinson's subjects. This "sunshine vitamin" surely can be a ray of sunshine for neurologically diseased subjects.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor impairments and it is correlated with loss of bone mineral density. This study aimed to analyze the effects of resistance training on bone metabolism, systemic homeostasis, body composition, and physical performance in people with PD. Thirteen subjects (age 64.83 ± 5.70) with PD diagnosis were recruited. Participants performed neuromuscular tests, body composition assessment, and blood sample analysis at baseline, and after an 11 weeks-training period. Each training session lasted 90 min, three times a week. The participants had significant improvements in the timed up and go (p < 0.01), sit to stand (p < 0.01), dominant peg-board (p < 0.05), dominant foot-reaction time (p < 0.01), and functional reach tests (p < 0.05). They showed better pressure foot distributions in the left forefoot (p < 0.05) and hindfoot (p < 0.05) and increased cervical right lateral bending angle (p < 0.05). The protocol affects bone metabolism markers osteocalcin (p < 0.05), calcium (p < 0.01), PTH (p < 0.01), the C-terminal telopeptide (CTX) (p < 0.01), and vitamin D (p < 0.05). Eleven weeks of resistance training improved manual dexterity, static and dynamic balance, reaction time, cervical ROM, and reduced bone loss in people with PD.

Abstract
Hip fractures are a common clinical problem with substantial morbidity and difficult recovery. Preexisting malnutrition has been shown to be common in those patients and a substantial risk factor for poorer outcomes, increased length of stay, and mortality. Additionally, great variability exists in reported malnutrition prevalence rates owing to the variety of nutrition screening and assessment tools utilized globally to identify malnutrition in these patients. Although previous data and a recent Cochrane review have not proven the value of nutrition supplements, we highlight several articles that show an opportunity for improvement in the nutrition care of patients sustaining hip fractures along with a multicenter randomized trial demonstrating the value of carefully designed nutrition intervention. There is also evidence that malnourished patients with hip fracture are still being undertreated. Current guidelines are reviewed, and continued efforts on the part of the clinicians to follow the guidelines as well as lowering the barriers to high-quality nutrition research is discussed.

Abstract
In recent years, many studies have investigated the correlations between Parkinson's disease (PD) and vitamin D status, but the conclusion remains elusive. The present review focuses on the associations between PD and serum vitamin D levels by reviewing studies on the associations of PD with serum vitamin D levels and vitamin D receptor (VDR) gene polymorphisms from PubMed, Web of Science, Cochrane Library, and Embase databases. We found that PD patients have lower vitamin D levels than healthy controls and that the vitamin D concentrations are negatively correlated with PD risk and severity. Furthermore, higher vitamin D concentrations are linked to better cognitive function and mood in PD patients. Findings on the relationship between VDR gene polymorphisms and the risk of PD are inconsistent, but the FokI (C/T) polymorphism is significantly linked with PD. The occurrence of FokI (C/T) gene polymorphism may influence the risk, severity, and cognitive ability of PD patients, while also possibly influencing the effect of Vitamin D3 supplementation in PD patients. In view of the neuroprotective effects of vitamin D and the close association between vitamin D and dopaminergic neurotransmission, interventional prospective studies on vitamin D supplementation in PD patients should be conducted in the future.

Abstract
Background: Parkinson’s disease (PD) is one of the most common neurodegenerative diseases (ND). Studies have demonstrated that biochemical markers have an association with PD. We aimed to investigate an association of biochemical markers including calcium, vitamin D, alkaline phosphatase (ALP), parathormone (PTH), and phosphorous with PD. Methods: This study was conducted on 139 PD patients and 100 healthy individuals. Serum levels of calcium, phosphorous, ALP, PTH and vitamin D were evaluated. Furthermore, student’s t-test and logistic regression models were used by SPSS. Results: The mean levels of calcium (9.4±0.7 and 9.0±0.8 ) and vitamin D (29.7±22.1 and 25.8±23.7) were higher in PD patients as compared with healthy controls, which only status of calcium being significantly different in the two groups (P<0.001). Levels of ALP (202.4±96.7 and 242.9±142.4) and phosphorous (3.6±0.6 and 4.22±1.1) were significantly different comparing PD patients with healthy subjects (P<0.01, P<0.001, respectively). ALP and phosphorous were significantly different in the two groups (OR=0.996, [CI 95%, 0.994-0.999], P<0.001, OR=0.475, [CI 95%, 0.325-0.694], P<0.001, respectively). Furthermore, increased levels of calcium resulted in an elevated risk of PD (OR=2.175, [CI 95% 1.377-3.435], P<0.001). Conclusion: Results show that mean levels of calcium are higher in PD patients relative to healthy controls. Thereby, higher levels of calcium may be associated with PD.

Abstract
BACKGROUND Hip fractures are a common injury in older people. Many studies worldwide have identified various risk factors for hip fracture. However, risk factors for hip fracture have not been studied extensively in New Zealand. The interRAI home care assessment consists of 236 health questions and some of these may be related to hip fracture risk. METHODS The cohort consisted of 45,046 home care clients aged 65 years and older, in New Zealand. Assessments ranged from September 2012 to October 2015. Hip fracture diagnosis was identified by linking ICD (International Classification of Diseases) codes from hospital admissions data (September 2012 to December 2015) to the interRAI home care data. Unadjusted and adjusted competing risk regressions, using the Fine and Gray method were used to identify risk factors for hip fracture. Mortality was the competing event. RESULTS The cohort consisted of 61% female with a mean age of 82.7 years. A total of 3010 (6.7%) of the cohort sustained a hip fracture after assessment. After adjusting for sociodemographic and potentially confounding variables falls (SHR (Subhazard Ratio) = 1.17, 95% CI (Confidence interval): 1.05-1.31), previous hip fracture (SHR = 4.16, 95% CI: 2.93-5.89), female gender (SHR = 1.38, 95% CI: 1.22-1.55), underweight (SHR = 1.67, 95% CI = 1.39-2.02), tobacco use (SHR = 1.56, 95% CI = 1.25-1.96), Parkinson's disease (SHR = 1.45, 95% CI: 1.14-1.84), and Wandering (SHR = 1.36, 95% CI: 1.07-1.72) were identified as risk factors for hip fracture. Shortness of breath (SHR = 0.80, 95% CI: 0.71-0.90), was identified as being protective against hip fracture risk. Males and females had different significant risk factors. CONCLUSIONS Risk factors for hip fracture similar to international work on risk factors for hip fracture, can be identified using the New Zealand version of the interRAI home care assessment.

Abstract
Introduction This study aimed to determine impacts on walking ability of spinal deformity and imbalance as distinct from movement disorders in Parkinson's disease (PD). Methods Thirty-two patients (15 males, 17 females; mean age 72.5 years) were analyzed. Three, thirteen, eleven, and five were at Hoehn-Yahr stages I, II, III, and IV, respectively. In addition to various spinal imbalance and deformity classifications the following were assessed: Cobb angle (CA) for scoliosis, thoracic kyphosis (TK) at T2-12, thoracolumbar kyphosis(TLK) at T12-L2, lumbar lordosis(LL) at L1-S1, pelvic tilt(PT), pelvic incidence(PI), and sagittal vertical axis(SVA). The Timed Up and Go (TUG) test was used to measure walking ability. Patients were evaluated using the Unified Parkinson's Disease Rating Scale (UPDRS) part III, and bone mineral density (BMD) scans. Results Nineteen patients (59%) had spinal deformity and imbalance within the following classifications: thoracic scoliosis, 1; thoracic kyphosis, 2; lumbar scoliosis, 15; Pisa syndrome, 3; camptocormia, 2. Mean values were 20.0° CA for scoliosis, 42.3° TK, 14.8° TLK, 26.7° LL, 20.8° PT, 48.8° PI, and 66.4 mm SVA. The mean TUG score was 13.9s. The UPDRS III mean was 36.6±24.5 points. Mean BMD was 0.856 g/cm2 at lumbar L2-4 and 0.585 g/cm2 at the femoral neck. UPDRS part III (P<0.001), LL (P<0.05), and femoral neck BMD (P<0.05) significantly correlated to TUG test results. Conclusions Distinct from the movement disorders of PD (UPDRS III), loss of normal LL and loss of BMD at the femoral neck were shown to be correlated with diminished walking ability (TUG test) in PD patients. When UPDRS improved in response to L-dopa, walking ability improved. In addition to any PD-specific interventions that contribute to the maintenance of ambulation, interventions specific to the restoration of LL, as well as early treatment for osteoporosis may positively affect HRQOL in PD.

Abstract
Background: Vitamin D is an important secosteroid which is involved the development and regulation of brain activity. Several studies have focused on exploring the relationship between serum vitamin D levels and Parkinson's disease (PD), but the conclusion remains ambiguous. Methods: We searched observational studies that explored the association between serum vitamin D levels and PD based on PubMed, EMBASE and Cochrane library from inception through to January 2018. The quality of included studies was evaluated by using Newcastle-Ottawa Scale (NOS). Statistical analysis of this meta-analysis was performed by Stata version 12.0 and R software. Results: Twenty studies with a total of 2,866 PD patients and 2,734 controls were included. Compared with controls, PD patients had lower serum vitamin D levels (WMD −3.96, 95%CI −5.00, −2.92), especially in higher latitude regions (WMD −4.20, 95%CI −5.66, −2.75). Assay methods contributed significantly to high heterogeneity. Furthermore, PD patients with deficient vitamin D levels had advanced risk (OR 2.08, 95%CI 1.35, 3.19) than those patients with insufficient ones (OR = 1.73, 95%CI 1.48, 2.03). In addition, serum vitamin D levels were also related to the severity of PD (WMD −5.27, 95%CI −8.14, −2.39) and the summary correlation coefficient showed strongly negative correlation (r = −0.55, 95%CI −0.73, −0.29). Moreover, the pooled correlation coefficient revealed that serum vitamin D levels were also negatively correlated to the Unified Parkinson's Disease Rating Scale III (UPDRS III) (r = −0.36, 95%CI −0.53, −0.16), but did not correlate with the duration of PD (P = 0.37) and age of patients (P = 0.49). Conclusion: Serum vitamin D levels are inversely associated with the risk and severity of PD. Our results provided an updated evidence of association between low vitamin D levels and PD and prompt the adjunctive therapeutic decisions about vitamin D replacement in PD.

Abstract
The relationship between Parkinson's disease (PD) and risk of hip fracture yielded inconsistent results. Therefore, we conducted the present systematic review and meta-analysis of published observational studies to assess the association between PD and risk of hip fracture. PubMed, ISI, EMBASE, and Cochrane databases were searched systematically to identify studies assessing the relationship between PD and the risk of hip fracture up to July 01, 2017. In addition, to find related articles, the reference section of retrieved articles was checked. Random-effects model was used for calculation of pooled hazard ratio (HR) and 95% confidence intervals (CI). Thirteen independent studies containing 564,947 participants were included in the meta-analysis. The overall results of included studies showed PD to be associated with the risk of hip fracture (HRoverall = 3.13, 95% CI 2.53-3.87) in women 3.11 (2.51-3.86) and men 2.60 (2.19-3.09). Our meta-analysis showed the direct association between PD and the risk of hip fracture in both men and women. However, due to the limitations of this study, further well-designed studies are required to confirm our findings.

Abstract
It has long been proven that neurogenesis continues in the adult brains of mammals in the dentatus gyrus of the hippocampus due to the presence of neural stem cells. Although a large number of studies have been carried out to highlight the localization of vitamin D receptor in hippocampus, the expression of vitamin D receptor in neurogenic dentatus gyrus of hippocampus in Parkinson's disease (PD) and the molecular mechanisms triggered by vitamin D underlying the production of differentiated neurons from embryonic cells remain unknown. Thus, we performed a preclinical in vivo study by inducing PD in mice with MPTP and showed a reduction of glial fibrillary acidic protein (GFAP) and vitamin D receptor in the dentatus gyrus of hippocampus. Then, we performed an in vitro study by inducing embryonic hippocampal cell differentiation with vitamin D. Interestingly, vitamin D stimulates the expression of its receptor. Vitamin D receptor is a transcription factor that probably is responsible for the upregulation of microtubule associated protein 2 and neurofilament heavy polypeptide genes. The latter increases heavy neurofilament protein expression, essential for neurofilament growth. Notably N-cadherin, implicated in activity for dendritic outgrowth, is upregulated by vitamin D.

Abstract
Background The cause of PD at present remains unknown. A number of epidemiological studies have been conducted across the globe to ascertain the disease burden and the possible risk factors. In this review, we analyze the various studies from East and West with an aim to observe the important similarities and differences in the disease occurrence and risk factor profile. Methods A comprehensive search of descriptive and analytical epidemiological studies was undertaken. The descriptive studies and meta-analysis providing the standardised population rates were selected. The demographics, ethnicity and geographical differences between East and West were analysed. In analytical epidemiology, more established and well-studied non-genetic risk factors for PD were reviewed utilising the prospective cohort studies, case control studies and meta-analysis where available. Results and Conclusion PD is more common with increasing age and shows male predominance, which is more obvious in Western studies. The PD prevalence and incidence rates are slightly lower in the East compared to the West. Incidence studies on different ethnic populations in the same country have also found a lower occurrence of PD amongst Easterners compared to Westerners. Setting methodological differences aside, studies from East and West suggest a role for both environmental and genetic risk factors in PD causation. Smoking, caffeine intake and pesticide exposure are well-established risk factors across regions. There is a robust data for dairy product consumption, urate levels and physical activity in the West while studies on certain risk factors like head injury and alcohol show conflicting and mixed results.

Abstract
Osteoporosis is a "hidden nonmotor face" of Parkinson's disease and a cause of considerable morbidity in the older general population and in Parkinson's disease patients. Some regard this as a "hidden epidemic." Women are overrepresented and have considerable problems related to osteoporosis. In general osteoporosis leads to reduced mobility aggravating the motor syndrome of PD. The nonmotor aspects and impact of osteoporosis in PD have remained unexplored. Possible nonmotor consequences include a range of pain syndromes related to local pain, fractures, falls, and injuries as well as pathological fractures and radiculopathy. In addition depression, sleep dysfunction, dementia, as well as fear of falling also complicate the clinical picture. Quality of life deteriorates both for the patient and career. Pathways of care do not always include assessments for osteoporosis and needs to become obligatory particularly in older female PD patients. Active management strategies then need to be undertaken for osteoporosis in PD. Related motor and nonmotor consequences also highlight the importance of multidisciplinary treatment in PD particularly when dealing with osteoporosis.

Abstract
Background: The risk of falls is higher in patients with Parkinsonism (PwP) as compared to other older adults, leading to adverse outcomes including fragility fractures. Osteoporosis is under-recognised and the current prevalence of fragility fractures is not well-studied. The objectives of this study are to determine the prevalence of fragility fractures in PwP, to measure the relationship of fractures with demography, severity and to measure predictors of adverse outcomes in this population. Method/Description: This was a retrospective observational cohort study based on the analysis of existing data for all the patients attending Caerphilly Movement Disorder Clinic. Information on demographics, the severity of Parkinsonism and fragility fractures was extracted electronically from the clinical workstation, clinic letters and coding from January 2015 to October 2016. Results: 397 people (mean age = 77.1 ± 9.4, 46% females) were studied. Of these, 77% (306/397) had Parkinsonism and 80% (244/306) had idiopathic Parkinson’s disease (PD). The mean Hoehn & Yahr Score at the time assessment was 3.09 ± 1.16. Additionally, 23.5% (72/306) were deemed to have osteoporosis based on the radiological evidence of fragility fractures. The PwP who sustained fractures were comparatively older (80.4 ± 12.1) and 70% (50/72) were females. The most common site for fractures was vertebral (47.2%; 34/72). Also, 22.2% of the sample (16/72) had suffered a fragility fracture before the diagnosis of PD. However, a majority (77.8%; 56/72) had sustained a fracture during the course of PD with a mean lapse of 6 years (range = 0–13 years) from initial diagnosis. Only 40% (29/72) of patients were prescribed osteoporosis drugs as per guidelines. There is a significant correlation of advancing age, severity and duration of PD with fragility fractures. The single best predictor of mortality is severity of PD, followed by age and fractures. Conclusions: There is a high prevalence of fragility fractures in patients attending movement disorder clinics, although 60% do not receive evidence-based medical treatment for the underlying osteoporosis. The prevalence of fragility fractures is positively correlated with the duration and severity of PD. We acknowledge the relatively small sample size as the study’s limitation.

Abstract
INTRODUCTION Parkinson's disease (PD) is a progressive, neurodegenerative disorder of multifactorial etiology affecting ∼1% of older adults. Research focused on linking PD to falls and bone fractures has been limited in Emergency Department (ED) settings, where most injuries are identified. We assessed whether injured U.S. ED admissions with PD diagnoses were more likely to exhibit comorbid fall- or non-fall related bone fractures and whether a PD diagnosis with a concomitant fall or bone fracture is linked to worse prognosis. METHODS We performed secondary analyses of 2010 Healthcare Utilization Project National ED Sample from 4,253,987 admissions to U.S. EDs linked to injured elderly patients. ED discharges with ICD-9-CM code (332.0) were identified as PD and those with ICD-9-CM code (800.0-829.0) were used to define bone fracture location. Linear and logistic regression models were constructed to estimate slopes (B) and odds ratios (OR) with 95% confidence intervals (CI). RESULTS PD admissions had 28% increased adjusted prevalence of bone fracture. Non-fall injuries showed stronger relationship between PD and bone fracture (ORadj = 1.33, 95% CI: 1.22-1.45) than fall injuries (ORadj = 1.06, 95% CI: 1.01-1.10). PD had the strongest impact on hospitalization length when bone fracture and fall co-occurred, and total charges were directly associated with PD only for fall injuries. Finally, PD status was not related to in-hospital death in this population. CONCLUSION Among injured U.S. ED elderly patient visits, those with PD had higher bone fracture prevalence and more resource utilization especially among fall-related injuries. No association of PD with in-hospital death was noted.

Abstract
Metabolic bone disease is a major public health concern, especially when it manifests as hip fracture which carries significant morbidity and mortality. Individuals with neurological disease are at higher risk of osteopenia, osteoporosis and fragility fracture compared to age-matched controls, yet this is under-appreciated by these patients. Clinician attention to this topic is therefore of importance and should address the bone health of men as well as women, a group in whom it may be an under-recognised problem. Evidence for optimal management of bone health in neurological disease remains to be defined, but a growing literature provides some useful guidance. This review focuses on two conditions, multiple sclerosis and Parkinson's disease, where research has been active over recent years. In neuroinflammation, shared immunological pathways between bone and brain are a current domain of interest and it will be intriguing to interrogate the action of emerging immunotherapies on these dual compartments.

Abstract
Background Stooped posture was mentioned in the original description of the characteristic features of Parkinson's disease (PD). Since then, a variety of postural, bone, and joint problems have become recognized as common aspects of the illness and deserve attention. Methods A Medline literature search for the period from 1970 to 2016 was performed to identify articles relevant to this topic. Keywords for the search included posture, spine, bone disorders, fractures, joint disorders, kyphosis, scoliosis, stooping, camptocormia, Pisa syndrome, frozen shoulder, anterocollis, dropped head syndrome, and pain in combination with PD. The articles were then reviewed to summarize clinical features, frequency, impact, pathophysiology, and treatment options for these conditions. Results Postural disorders (kyphoscoliosis, camptocormia, Pisa syndrome, dropped head syndrome), bone mineralization disorders (osteoporosis, bone fractures), and joint disorders (frozen shoulder, dystonia involving joints, joint pain) are often seen in association with PD. Treatment options for these conditions are varied and may include medications, physical therapy, or surgical interventions. Conclusions Posture, bone, and joint disorders are common in patients with PD; they often produce added disability, and they may be treatable.

Abstract
IMPORTANCE Greater body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) is associated with improved survival among persons with Huntington disease or amyotrophic lateral sclerosis. Weight loss is common among persons with Parkinson disease (PD) and is associated with worse quality of life. OBJECTIVE To explore the association between change in BMI, Unified Parkinson's Disease Rating Scale (UPDRS) motor and total scores, and survival among persons with PD and to test whether there is a positive association between BMI at randomization and survival. DESIGN, SETTING, AND PARTICIPANTS Secondary analysis (from May 27, 2014, to October 13, 2015) of longitudinal data (3-6 years) from 1673 participants who started the National Institute of Neurological Disorders and Stroke Exploratory Trials in PD Long-term Study-1 (NET-PD LS-1). This was a double-blind randomized placebo-controlled clinical trial of creatine monohydrate (10 g/d) that was performed at 45 sites throughout the United States and Canada. Participants with early (within 5 years of diagnosis) and treated (receiving dopaminergic therapy) PD were enrolled from March 2007 to May 2010 and followed up until September 2013. MAIN OUTCOMES AND MEASURES Change across time in motor UPDRS score, change across time in total UPDRS score, and time to death. Generalized linear mixed models were used to estimate the effect of BMI on the change in motor and total UPDRS scores after controlling for covariates. Survival was analyzed using Cox proportional hazards models of time to death. A participant's BMI was measured at randomization, and BMI trajectory groups were classified according to whether participants experienced weight loss ("decreasing BMI"), weight stability ("stable BMI"), or weight gain ("increasing BMI") during the study. RESULTS Of the 1673 participants (mean [SD] age, 61.7 [9.6] years; 1074 [64.2%] were male), 158 (9.4%) experienced weight loss (decreasing BMI), whereas 233 (13.9%) experienced weight gain (increasing BMI). After adjusting for covariates, we found that the weight-loss group's mean (SE) motor UPDRS score increased by 1.48 (0.28) (P < .001) more points per visit than the weight-stable group's mean (SE) motor UPDRS score. The weight-gain group's mean (SE) motor UPDRS score decreased by -0.51 (0.24) (P = .03) points per visit, relative to the weight-stable group. While there was an unadjusted difference in survival between the 3 BMI trajectory groups (log-rank P < .001), this was not significant after adjusting for covariates. CONCLUSIONS AND RELEVANCE Change in BMI was inversely associated with change in motor and total UPDRS scores in the NET-PD LS-1. Change in BMI was not associated with survival; however, these results were limited by the low number of deaths in the NET-PD LS-1. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00449865.

Abstract
KEY POINTS Significantly lower BMD in PD compared to healthy subjects in both genders.Less than 35 mg(2)/dl(2) of Ca-P product in >80% of PD patients.Significant correlations between BMD and severity of PD.Lower BMD at H&Y stage III/IV than that at H&Y stage I/II. OBJECTIVES Although several lines of evidence have suggested that patients with Parkinson's disease (PD) have a higher risk of osteoporosis and fracture, the association between bone mineral density (BMD) and severity of PD patients is unknown. METHODS We performed a cross-sectional study of 54 patients with PD and 59 healthy age-matched controls. Multiple clinical scales were used to evaluate the severity of PD, and serum levels of calcium, phosphorus, and homocysteine were measured to determine BMD's association with PD severity. RESULTS BMD in PD patients was significantly lower than that in healthy controls. The BMD scores of the spine, femoral neck (FN), and hip were lower in females than in males in the healthy group. In the PD group, BMD in the hip was significantly lower in females compared to males. There was a negative correlation between daily l-DOPA dosage and BMD in the spine and hip in the PD group, while BMD in the spine, neck, and hip was significantly correlated with severity of PD. Besides, we found that among the lumbar spine (LS), FN, and hip, bone loss in the LS was the most severe in PD patients based on the T-scores. CONCLUSION Our findings support the hypothesis that patients with PD have a higher risk of osteoporosis, and that low BMD in the spine, FN, and hip may indirectly reflect the severity of PD. Our findings have prompted us to pay more attention to osteoporosis in the LS in Chinese PD patients.

Abstract
UNLABELLED The association between Parkinson's disease and fracture was not completely understood. This nationwide study investigated increased risk of fracture in patients with Parkinson's disease. In the nested cohort study, Parkinson's disease was associated with pneumonia, septicemia, stroke, urinary tract infection, and mortality after fracture admission. INTRODUCTION Falls are a common complication in people with Parkinson's disease (PD). This study evaluated fracture risk and post-fracture outcomes in patients with PD. METHODS We identified 1,423 adults aged 40 years and older newly diagnosed with PD using the Taiwan National Health Insurance Research Database from 2000 to 2003. Comparison cohort consisted of 5,692 adults without PD randomly selected from the same dataset, frequency matched in age and sex. Followed-up events of fracture from January 1, 2000, until December 31, 2008, were ascertained from medical claims. Adjusted hazard ratios (HR) and 95 % confidence interval (CI) of fracture associated with PD were evaluated. Another nested cohort study of 397,766 hospitalized fracture patients analyzed for adjusted odds ratios (ORs) and 95 % CIs of adverse events after fracture among patients with and without PD between 2004 and 2010. RESULTS The incidences of fracture for people with and without PD were 39.5 and 23.9 per 1,000 person-years, respectively (p < 0.0001). Compared with control, the adjusted HR of fracture was 2.25 (95 % CI 1.97-2.58) for PD patients. Previous PD was associated with risks of pneumonia (OR 1.44, 95 % CI 1.36-1.52), septicemia (OR 1.41, 95 % CI 1.33-1.49), stroke (OR 1.40, 95 % CI 1.32-1.50), urinary tract infection (OR 1.53, 95 % CI 1.46-1.61), and mortality (OR 1.25, 95 % CI 1.15-1.35) after fracture. CONCLUSIONS PD was associated with higher risk of fracture. Patients with PD had more complications and mortality after fracture. Fracture prevention and attention to post-fracture adverse events are needed for this susceptible population.

Abstract
INTRODUCTION Degenerative spondylosis and kyphoscoliosis are increasingly recognized entities in patients with Parkinson's disease. Surgical treatment with spinal fusion can be complicated due to poor bone quality and muscular dysfunction in this patient population. The goal of this paper is to investigate surgical outcomes in Parkinson's patients undergoing spine surgery. METHODS We performed a literature review using the PubMed and Google Scholar search engines investigating "Parkinson's disease and spinal fusion surgery" from the period of 2000 to 2013. The inclusion criteria included only English articles with Parkinson's patients that underwent spinal surgery. We identified and reviewed all six articles that included ninety-five patients with Parkinson's disease who underwent spinal surgery. RESULTS A total of 95 patients with Parkinson's disease who underwent spinal fusion surgery were reviewed with average patient age of 69 and a 3:4 male to female ratio. With an average follow up of 40 months, 46 out of 73 patients (63%) were judged to have satisfactory outcomes with poor outcomes noted in the remaining 37%. These included but were not limited to pseudoarthrosis, hardware failure/pullout, development of adjacent level disease, persistent kyphosis or sagittal imbalance, and no improvement or worsening in their postoperative visual analog pain scale. There was a 45% (29/65) revision rate and a 59% (30/51) complication rate following the index procedure. CONCLUSION It remains unclear whether Parkinson's patients benefit from spinal fusion surgery. Further prospective research is warranted to investigate surgical outcomes in this subset of patients.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by the death of dopamine-generating cells in the substantia nigra (SN). Acupuncture stimulation results in an enhanced survival of dopaminergic neurons in the SN in Parkinsonism animal models. The present study investigated changes in gene expression profiles measured using whole transcript array in the SN region related to the inhibitory effects of acupuncture in a chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) Parkinsonism model. In this model, acupuncture stimulation at GB34 and LR3 attenuated the decrease in tyrosine hydroxylase in the SN region; stimulation at non-acupoints did not suppress this decrease. Gene array analysis revealed that 22 (10 annotated genes: Cdh1, Itih2, Mpzl2, Rdh9, Serping1, Slc6a13, Slc6a20a, Slc6a4, Tph2, and Ucma) probes that were up-regulated in MPTP animals relative to controls were exclusively down-regulated by acupuncture stimulation. In addition, 17 (two annotated genes: 4921530L21Rik and Gm13931) probes that were down-regulated in MPTP animals compared to controls were exclusively up-regulated by acupuncture stimulation. These findings indicate that the 39 probes (12 annotated genes) affected by MPTP and acupuncture may be responsible for the inhibitory effects of acupuncture on degeneration-related gene expression in the SN following damage induced by MPTP intoxication.

Abstract
Objectives: To systematically review the evidence investigating the effectiveness of resistance training on strength and physical function in people with Parkinson’s disease. Data sources: Seven electronic databases (COCHRANE, CINAHL, Medline ISI, Psycinfo, Scopus, Web of Science ISI and Embase) were systematically searched for full-text articles published in English between 1946 and November 2014 using relevant search terms. Review methods: Only randomized controlled trials investigating the effects of resistance training on muscle strength and physical function in people with Parkinson’s disease were considered. The PEDro scale was used to assess study quality. Studies with similar outcomes were pooled by calculating standardized mean differences (SMD) using fixed or random effects model, depending on study heterogeneity. Results: Seven studies, comprising of 401 participants with early to advanced disease (Hoehn & Yahr stage 1 to 4), were included. The median quality score was 6/10. The meta-analyses demonstrated significant SMD in favour of resistance training compared to non-resistance training or no intervention controls for muscle strength (0.61; 95% CI, 0.35 to 0.87; P <0.001), balance (0.36; 95% CI, 0.08 to 0.64; P = 0.01) and parkinsonian motor symptoms (0.48; 95% CI, 0.21 to 0.75; P < 0.001) but not for gait, balance confidence and quality of life. Conclusion: This review demonstrates that moderate intensity progressive resistance training, 2-3 times per week over 8-10 weeks can result in significant strength, balance and motor symptoms gains in people with early to moderate Parkinson’s disease.

Abstract
Parkinson's disease (PD) is the second most common neurodegenerative disorder. The majority of cases do not arise from purely genetic factors, implicating an important role of environmental factors in disease pathogenesis. Well-established environmental toxins important in PD include pesticides, herbicides, and heavy metals. However, many toxicants linked to PD and used in animal models are rarely encountered. In this context, other factors such as dietary components may represent daily exposures and have gained attention as disease modifiers. Several in vitro, in vivo, and human epidemiological studies have found a variety of dietary factors that modify PD risk. Here, we critically review findings on association between dietary factors, including vitamins, flavonoids, calorie intake, caffeine, alcohol, and metals consumed via food and fatty acids and PD. We have also discussed key data on heterocyclic amines that are produced in high-temperature cooked meat, which is a new emerging field in the assessment of dietary factors in neurological diseases. While more research is clearly needed, significant evidence exists that specific dietary factors can modify PD risk.

Abstract
The role of vitamin D in bone health has been known for over a century. More recent research has suggested that vitamin D may play a role in the muscular, immune, endocrine, and central nervous systems. Animal research suggests that vitamin D may have some protective effects against toxic insults that are known to damage dopamine cells, the primary cells to degenerate in PD. Persons with PD tend to have lower vitamin D levels than persons of similar ages without PD. Vitamin D levels are generally associated with bone mineral density (BMD) in persons with PD, but simply giving vitamin D does not appear to improve BMD. Results of genetic studies examining polymorphism of the vitamin D receptor and PD risk, severity, or age at onset have shown variable results, with FokI CC seeming to possibly carry some increased risk of PD. Amount of sun exposure and vitamin D levels in earlier life may influence the risk of developing PD. Cross-sectional research suggests a relationship between vitamin D levels and severity of PD symptoms. A single intervention study did show some improvement in PD with vitamin D supplementation. Vitamin D may have effects on PD symptoms and perhaps even on the risk of disease development or disease progression. More well designed intervention studies are needed to confirm the effect of vitamin D on PD symptoms. Human neuroprotection studies are needed, but probably not feasible until better biomarkers are established.

Abstract
Parkinson disease (PD) is a progressive, neurodegenerative movement disorder. PD was originally attributed to neuronal loss within the substantia nigra pars compacta, and a concomitant loss of dopamine. PD is now thought to be a multisystem disorder that involves not only the dopaminergic system, but other neurotransmitter systems whose role may become more prominent as the disease progresses (189). PD is characterized by four cardinal symptoms, resting tremor, rigidity, bradykinesia, and postural instability, all of which are motor. However, PD also may include any combination of a myriad of nonmotor symptoms (195). Both motor and nonmotor symptoms may impact the ability of those with PD to participate in exercise and/or impact the effects of that exercise on those with PD. This article provides a comprehensive overview of PD, its symptoms and progression, and current treatments for PD. Among these treatments, exercise is currently at the forefront. People with PD retain the ability to participate in many forms of exercise and generally respond to exercise interventions similarly to age-matched subjects without PD. As such, exercise is currently an area receiving substantial research attention as investigators seek interventions that may modify the progression of the disease, perhaps through neuroprotective mechanisms.

Abstract
BACKGROUND Previous studies have shown that patients with Parkinson's disease (PD) are at increased risk of fractures. However, no specific prediction model for fracture estimation among PD patients is currently available. Therefore, the aim of this study was to develop a simple score for estimating the 5-year osteoporotic and hip fracture risks among patients with PD. METHODS The U.K. Clinical Practice Research Datalink (1987-2011) was used to identify incident PD patients. Cox proportional-hazards models were used to calculate the 5-year risks of osteoporotic and hip fracture among PD patients. The regression model was fitted with various risk factors for fracture and the final Cox model was converted into integer risk scores. RESULTS We identified 4411 incident PD patients without a history of osteoporotic treatment. The 5-year risks of osteoporotic and hip fracture were plotted in relation to the risk score. Risk scores increased with age, female gender, history of renal disease and history of dementia. The C-statistic, which is a parameter to test the internal validity of the model, was reasonable for the prediction of osteoporotic fracture (0.69) and hip fracture (0.73). CONCLUSION In this study, we developed a simple model to estimate 5-year fracture risk among incident PD patients. It may be useful in daily practice after external validation.

Abstract
UNLABELLED The aim of the study was to determine fracture risk in incident Parkinson's disease (PD) patients. This study showed that fracture risk assessment may be indicated among patients with PD, in particular when they have recently used selective serotonin re-uptake inhibitors or high-dose antipsychotics, or have a history of fracture, falling, low body mass index (BMI) or renal disease. INTRODUCTION PD is a movement disorder associated with falling and detrimental effects on bone. Both are recognized risk factors for fracture. Therefore, the aim was to determine fracture risk in incident PD patients stratified by treatment, severity, duration of disease and related comorbidities. METHODS We conducted a retrospective cohort study using the UK General Practice Research Database (1987-2011). Each PD patient was matched by age, sex, calendar time and practice to a control patient without history of PD. RESULTS We identified 4,687 incident PD patients. Compared to controls, a statistically significant increased risk was observed for any fracture (adjusted hazard ratio [AHR], 1.89; 95 % confidence interval [CI], 1.67-2.14), osteoporotic fracture (AHR, 1.99; 95 % CI, 1.72-2.30) and hip fracture (AHR 3.08; 95 % CI, 2.43-3.89). Fracture risk further increased with history of fracture, falling, low BMI, renal disease, antidepressant use and use of high-dose antipsychotics. CONCLUSION This study showed that incident PD patients have a statistically significant increased risk of fracture. Therefore, fracture risk assessment may be indicated among PD patients, who, besides the general risk factors for fracture, like increasing age and female gender, have recently used selective serotonin re-uptake inhibitors or high-dose antipsychotics or have a history of fracture, falling, low BMI or renal disease.

Abstract
Purpose Vitamin D supplementation is suggested to reduce the risk of falls in older institutionalized or ambulatory individuals by 20%. The present study was undertaken to address the reduced risk, by vitamin D supplementation, of falls and hip fractures in patients with vascular Parkinsonism (VP) and Parkinson’s disease (PD). Patients and methods In the open-label-study, 94 elderly patients with VP and 92 age-matched patients with PD were followed for 2 years. All patients received 1200 IU ergocalciferol daily. The number of falls per person and incidence of hip fractures were compared between the two groups. Results At baseline, serum 25-hydroxyvitamin D (25-OHD) levels were in the deficient range (<25 nmol/L) in all patients, and vitamin D treatment enhanced serum 25-OHD and 1,25-dihydroxyvitamin D levels in both groups. Improved muscle strength of lower extremities was observed in both groups. There was significant difference between the two groups in the number of falls per subject during the 2 years (1.9 ± 0.5 in the PD group and 0.8 ± 0.4 in the VP group, P < 0.001). Hip fractures occurred in seven of 88 in the PD group and one in 90 of the VP group during the 2-year study period (P = 0.035). Conclusion It is suggested that vitamin D decreases falls and hip fractures in VP by increasing muscle strength but not in PD.

Abstract
During the last decade, our view on the skeleton as a mere solid physical support structure has been transformed, as bone emerged as a dynamic, constantly remodeling tissue with systemic regulatory functions including those of an endocrine organ. Reflecting this remarkable functional complexity, distinct classes of humoral and intracellular regulatory factors have been shown to control vital processes in the bone. Among these regulators, nuclear receptors (NRs) play fundamental roles in bone development, growth, and maintenance. NRs are DNA-binding transcription factors that act as intracellular transducers of the respective ligand signaling pathways through modulation of expression of specific sets of cognate target genes. Aberrant NR signaling caused by receptor or ligand deficiency may profoundly affect bone health and compromise skeletal functions. Ligand dependency of NR action underlies a major strategy of therapeutic intervention to correct aberrant NR signaling, and significant efforts have been made to design novel synthetic NR ligands with enhanced beneficial properties and reduced potential negative side effects. As an example, estrogen deficiency causes bone loss and leads to development of osteoporosis, the most prevalent skeletal disorder in postmenopausal women. Since administration of natural estrogens for the treatment of osteoporosis often associates with undesirable side effects, several synthetic estrogen receptor ligands have been developed with higher therapeutic efficacy and specificity. This review presents current progress in our understanding of the roles of various nuclear receptor-mediated signaling pathways in bone physiology and disease, and in development of advanced NR ligands for treatment of common skeletal disorders.

Abstract
BACKGROUND patients with Parkinson's disease (PD) have a high risk of sustaining osteoporotic fractures as a result of falls and reduced bone mass. OBJECTIVE to summarise the underlying pathophysiological mechanisms of bone loss in PD by reviewing the available literature. METHODS a Medline search was performed for articles published between January 1975 and January 2011, using the keywords 'bone mineral density', 'bone loss', 'bone metabolism', 'osteoporosis', 'osteopenia', 'Parkinson's disease' and 'Parkinsonism'. RESULTS PD patients have a lower bone mineral density (BMD) than age-matched controls. Bone loss in PD is multifactorial, resulting from immobility, decreased muscle strength, and low body weight. Vitamin D deficiency is also important, not only because it reduces BMD, but also because cell function in the substantia nigra depends on vitamin D. Lastly, hyperhomocysteinaemia, an independent risk factor for osteoporosis, is common in PD, due to levodopa use, as well as vitamin B12 and folic acid deficiency. A few studies have demonstrated that treatment with bisphosphonates, vitamin D and calcium can increase BMD and reduce fractures in PD patients. CONCLUSION bone loss in PD is multifactorial. It is clinically important because of the concomitant risk of fractures. Screening for osteoporosis should be considered more often, and therapeutic interventions should be initiated.

Abstract
Parkinson's disease (PD) is the second most common form of neurodegeneration in the elderly population. Clinically, it is characterized by tremor, rigidity, slowness of movement, and postural imbalance. A significant association between low serum vitamin D and PD has been demonstrated, suggesting that elevated vitamin D levels might provide protection against PD. Genetic studies have helped identify a number of proteins linking vitamin D to PD pathology, including the major histocompatibility complex (MHC) class II, the vitamin D receptor (VDR), cytochrome P450 2D6 (CYP2D6), chromosome 22, the renin-angiotensin system (RAS), heme oxygenase-1 (HO-1), poly(ADP-ribose) polymerase-1 gene (PARP-1), neurotrophic factor (NTF), and Sp1 transcription factor. Vitamin D has also been implicated in PD through its effects on L-type voltage-sensitive calcium channels (L-VSCC), nerve growth factor (NGF), matrix metalloproteinases (MMPs), prostaglandins (PGs) and cyclooxygenase-2 (COX-2), reactive oxygen species (ROS), and nitric oxide synthase (NOS). A growing body of evidence suggests that vitamin D supplementation may be beneficial for PD patients. Among the different forms of vitamin D, calcitriol (1,25-dihydroxyvitamin D3) is best indicated for PD, because it is a highly active vitamin D3 metabolite with an appropriate receptor in the central nervous system (CNS).

Abstract
Prior work suggested that patients with Parkinson's disease (PD) have a lower Body Mass Index (BMI) than controls, but evidence is inconclusive. We therefore conducted a meta-analysis on BMI in PD. We searched MEDLINE, EMBASE, Cinahl and Scopus to identify cohort studies on BMI in PD, published before February 2011. Studies that reported mean BMI for PD patients and healthy controls were eligible. Twelve studies were included, with a total of 871 patients and 736 controls (in three studies controls consisted of subjects from other published studies). Our primary aim was to assess differences in BMI between patients and controls; this was analyzed with random effects meta-analysis. Our secondary aim was to evaluate the relation with disease severity (Hoehn and Yahr stage) and disease duration, using random effects meta-regression. PD patients had a significantly lower BMI than controls (overall effect 1.73, 95% CI 1.11-2.35, P<0.001). Pooled data of seven studies showed that patients with Hoehn and Yahr stage 3 had a lower BMI than patients with stage 2 (3.9, 95% CI 0.1-7.7, P<0.05). Disease duration was not associated with BMI. Because a low body weight is associated with negative health effects and a poorer prognosis, monitoring weight and nutritional status should be part of PD management.

Abstract
Parkinson disease (PD) is a neurodegenerative disorder characterized by progressive motor and nonmotor impairments. These impairments incline many patients towards a sedentary lifestyle, which has many deleterious consequences. Accumulating evidence suggests that patients with PD might benefit from physical activity and exercise in a number of ways, from general improvements in health to disease-specific effects and, potentially, disease-modifying effects (suggested by animal data). Many issues remain to be addressed, including the need to perform clinical trials to demonstrate these presumed benefits of physical activity and exercise in patients with PD. These trials must also address safety issues, such as an increased risk of falls and cardiovascular complications in more-active patients. Identifying ways to induce a sustained behavioral change, using specifically tailored programs that address potential barriers such as depression, apathy and postural instability, may lead to an improved quality of life in individuals with PD.

Abstract
SUMMARY The effect of dopaminergic medication on the risk of hip/femur fractures is not clear. Our results showed a nearly twofold increased risk of hip/femur fractures in current dopaminergic drug users. Concomitant use of antidepressants further increased this risk. Fracture risk assessment may be warranted in elderly users of dopaminergic drugs. INTRODUCTION Dopaminergic drugs, often used in the treatment of Parkinson's disease, have several pharmacological effects that may increase or decrease the risk of falling and fractures. Thus, the effect of dopaminergic medication on the risk of hip/femur fractures is not clear. The objective of the study was to examine the effect of dopaminergic medication and concomitant use of psychotropics on the risk of hip/femur fractures taking into account the timing of dopaminergic drug use. METHODS A population-based case-control study in the PHARMO database was conducted for the period 1991 to 2002. Cases were patients aged 18 years and older with a first hip or femur fracture and matched to four control patients by year of birth, sex and geographical region. RESULTS The study population included 6,763 cases and 26,341 controls. Current use of dopaminergic drugs (1-30 days before the index date) was associated with an increased risk of hip/femur fractures compared to never use (OR(adj) 1.76, 95% CI = 1.39-2.22), but this excess risk rapidly dropped to baseline levels when treatment had been discontinued >1 year ago. Concomitant use of antidepressants among current dopaminergic drug users further increased the risk of hip/femur fractures (OR(adj) 3.51, 95% CI = 2.10-5.87) while there was no additional risk with concomitant use of other psychotropics. CONCLUSIONS Although the observed association between dopaminergic drugs and fracture risk may not be entirely causal, due to absence of information on the (severity of the) underlying disease, fracture risk assessment may be warranted in elderly users of dopaminergic drugs.

Abstract
OBJECTIVE To determine the pathogenesis of the stooped posture in Parkinson disease (PD), we prospectively studied fractures in a cohort of patients with Parkinson disease for 5 yrs. DESIGN At baseline, we recorded the dietary intake of vitamin D and serum concentrations of parathyroid hormone and 25-hydroxyvitamin D. Bone mineral density and lateral thoracic and lumbar spine radiographs were obtained at baseline and every year for 5 yrs. RESULTS During the 5-yr study period, stooped posture developed in 34 patients; the rest of the 58 patients did not show stooped posture. At baseline, mean serum 25-hydroxyvitamin D and parathyroid hormone levels were 10.9 ng/ml and 73.1 pg/ml, respectively, in the stooped group and 18.6 ng/ml and 56.4 pg/ml, respectively, in the nonstooped group. Bone mineral density in the stooped group was significantly lower than in the nonstooped group. Dietary intake of vitamin D in the stooped group was significantly lower than in the nonstooped group. During the study period, 19 (22%) patients in the nonstooped group developed new vertebral fracture, compared with 23 (100%) patients in the stooped group. The mean ± SD percentage changes in bone mineral density were -6.5 ± 0.6 in the stooped group and -3.8 ± 0.8 in the nonstooped group. Mean serum levels of 25-hydroxyvitamin D after 5 yrs were 7.0 ng/ml in the stooped group and 14.1 ng/ml in the nonstooped group. CONCLUSIONS Stooped posture in Parkinson disease may be caused by vertebral fractures resulting from vitamin D deficiency with compensatory hyperparathyroidism. Vitamin D supplementation may reduce stooped posture in patients with Parkinson disease.

Abstract
BACKGROUND Although Parkinson's disease (PD) is a well recognised risk factor for falls, how this disease and its therapy affect postural stability and leaning balance remains unclear. The aim of this study was to examine the effects of PD and levodopa on postural sway and leaning balance. METHODS Performances of 28 PD participants {median [inter-quartile range (IQR)] duration of PD: 10 (6-13) years, median (IQR) UPDRS motor score "off": 22 (14-31) "on" and "off" levodopa were compared with 28 age- and gender-matched healthy controls on two measures of controlled leaning balance [ratio of anterior-posterior (AP) sway to maximal balance range (MBR) and coordinated stability]. RESULTS PD participants had greater ratio of AP sway to MBR than controls (P < 0.001), indicating that they swayed more as a proportion of their limits of stability, both "off" and "on" levodopa (P < 0.001). They also performed poorer in the coordinated stability test both "off" and "on" levodopa compared to controls (P < 0.001, for both), suggesting greater difficulty in controlling the center of mass at or near the limits of stability. Levodopa improved PD "participants" leaning balance (P < 0.001) and reduced the AP sway to MBR ratio (P < 0.001), although not to the level of controls. CONCLUSIONS PD participants perform poorer than controls in leaning balance tests but significantly improve when "on" levodopa. Regardless of medication state, PD participants sway markedly more as a percentage of their limits of stability than controls suggesting a higher risk of falling.

Abstract
INTRODUCTION Despite clear deficits in postural control, most clinical examination tools lack accuracy in identifying persons with Parkinson disease (PD) who have fallen or are at risk for falls. We assert that this is in part due to the lack of ecological validity of the testing. METHODS To test this assertion, we examined the responsiveness and predictive validity of the Functional Gait Assessment (FGA), the Pull test, and the Timed up and Go (TUG) during clinically defined ON and OFF medication states. To address responsiveness, ON/OFF medication performance was compared. To address predictive validity, areas under the curve (AUC) of receiver operating characteristic (ROC) curves were compared. Comparisons were made using separate non-parametric tests. RESULTS Thirty-six persons (24 male, 12 female) with PD (22 fallers, 14 non-fallers) participated. Only the FGA was able to detect differences between fallers and non-fallers for both ON/OFF medication testing. The predictive validity of the FGA and the TUG for fall identification was higher during OFF medication compared to ON medication testing. The predictive validity of the FGA was higher than the TUG and the Pull test during ON and OFF medication testing. DISCUSSION In order to most accurately identify fallers, clinicians should test persons with PD in ecologically relevant conditions and tasks. In this study, interpretation of the OFF medication performance and use of the FGA provided more accurate prediction of those who would fall.

Abstract
OBJECTIVE To review the literature and to identify practice gaps in the management of the hospitalized Parkinson's disease (PD) patient. BACKGROUND Patients with PD are admitted to hospitals at higher rates, and frequently have longer hospital stays than the general population. Little is known about outpatient interventions that might reduce the need for hospitalization and also reduce hospital-related complications. METHODS A literature review was performed on PubMed about hospitalization and PD between 1970 and 2010. In addition, in press peer-reviewed papers or published abstracts known to the authors were included. Information was reviewed by a National Parkinson Foundation workgroup and a narrative review article was generated. RESULTS Motor disturbances in PD are believed to be a causal factor in the higher rates of admissions and complications. However, other conditions are commonly recorded as the primary reason for hospitalization including motor complications, reduced mobility, lack of compliance, inappropriate use of neuroleptics, falls, fractures, pneumonia, and other important medical problems. There are many relevant issues related to hospitalization in PD. Medications, dosages and specific dosage schedules are critical. Staff training regarding medications and medication management may help to avoid complications, particularly those related to reduced mobility, and aspiration pneumonia. Treatment of infections and a return to early mobility is also critical to management. CONCLUSIONS Educational programs, recommendations, and guidelines are needed to better train interdisciplinary teams in the management of the PD patient. These initiatives have the potential for both cost savings and improved outcomes from a preventative and a hospital management standpoint.
