Demographic development in Germany has led to an aging of the population. Particularly for these patients, osteoporosis-induced vertebral fractures represent a significant decrease in quality of life and level of activity. According to current guidelines, the initial treatment of stable osteoporotic vertebral fractures is conservative management with analgesic, anti-osteoporotic, physical therapy, and orthotic measures as first line options. Personal experience, however, suggests that patients benefit from timely surgical treatment through rapid improvement of pain symptoms and thus, more rapid mobilization. The poor bone quality of elderly patients presents the treating spine surgeon a challenge in achieving stable spinal fusion with or without support, for example, through augmentation. Minimally invasive procedures have increasingly established themselves for such purposes in recent years. With over 1000 fracture treatments in the last 3.5 years, we have developed a differentiated treatment concept depending on patient age and fracture morphology, which we would like to introduce. Unstable fractures with posterior edge involvement are stabilized from posterior with a percutaneous fixator. Patients over 60 years were treated percutaneously with a polyaxial screw system. Increased stability was achieved by PMMA cement augmentation of the fenestrated screws. In elderly patients with Magerl A3 fractures without neurologic deficit, the index vertebra is supplementally treated with kyphoplasty (hybrid treatment). In acute, stable osteoporotic vertebral fractures with severe pain despite analgesics, we perform kyphoplasty, which is possible even in high thoracic fractures to T3 with smaller balloons and thinner trocars. Vertebroplasty is another option in the lumbar and lower thoracic spine. Because of invasiveness, extended posterior-anterior correction procedures are generally avoided in this population, which has frequent multiple comorbidities.

Calcitonin, a potent hypocalcemic hormone, plays a vital role in inhibiting osteoclastic activities and suppressing bone removal. The physiological characteristics of calcitonin have long been discussed, along a few recommending calcitonin as a vestigial hormone. The basis for this article is to discuss the role of low and high levels of calcitonin in normal and osteoprotic bone turnover. The effect of calcitonin on the receptor activator of nuclear factor kappa-ligand and osteoclasts has been demonstrated using numerical simulations. This behavior recommends that treatment of osteoporosis via calcitonin does not provide the required upshots. For effectiveness calcitonin must be advised along with a combined therapy like aspirin which agrees with the experimental results available in the literature.

Receptor activator of Nfkb ligand (RANKL) activates, while osteoprotegerin (OPG) inhibits, osteoclastogenesis. In turn a neutralizing Ab against RANKL, denosumab improves bone strength in osteoporosis. OPG also improves muscle strength in mouse models of Duchenne's muscular dystrophy (mdx) and denervation-induce atrophy, but its role and mechanisms of action on muscle weakness in other conditions remains to be investigated. We investigated the effects of RANKL inhibitors on muscle in osteoporotic women and mice that either overexpress RANKL (HuRANKL-Tg+), or lack Pparb and concomitantly develop sarcopenia (Pparb-/-). In women, denosumab over 3 years improved appendicular lean mass and handgrip strength compared to no treatment, whereas bisphosphonate did not. HuRANKL-Tg+ mice displayed lower limb force and maximal speed, while their leg muscle mass was diminished, with a lower number of type I and II fibers. Both OPG and denosumab increased limb force proportionally to the increase in muscle mass. They markedly improved muscle insulin sensitivity and glucose uptake, and decrease anti-myogenic and inflammatory gene expression in muscle, such as myostatin and protein tyrosine phosphatase receptor-γ. Similarly, in Pparb-/-, OPG increased muscle volume and force, while also normalizing their insulin signaling and higher expression of inflammatory genes in skeletal muscle. In conclusions, RANKL deteriorates, while its inhibitor improves, muscle strength and insulin sensitivity in osteoporotic mice and humans. Hence denosumab could represent a novel therapeutic approach for sarcopenia.

Effective strategies to improve health education, food choices, and physical activity are vital for people with intellectual and developmental disabilities (IDD), as their sedentary lifestyles and high fat diets are contributing to poor health, such as cardiovascular disease, osteoporosis, hypertension, Type II diabetes, and obesity. This study examined the effectiveness of a peer-led health promotion program for people with IDD. One group pre/post-test design was used to test the feasibility and effectiveness of the 12-week HealthMessages Program for three groups: peer health coaches (PHCs), mentors, and peer participants. A total of 379 volunteers participated including PHCs people with IDD (n = 33), mentors-staff from community organizations (n = 35), and peer participants-peers with IDD (n = 311). Following the intervention and 12-week HealthMessages Program, PHCs had significant changes in physical activity and hydration knowledge, mentors had significant changes in self-efficacy scores, and peer participants had significant changes in physical activity and hydration knowledge, social supports, and total health behaviors. A dyad approach supported PHCs and mentors to implement a successful HealthMessages Program with their peers.
- Cav 1.2 regulates osteogenesis of bone marrow-derived mesenchymal stem cells via canonical Wnt pathway in age-related osteoporosis. [Journal Article]
- ACAging Cell 2019 May 23; :e12967
- CONCLUSIONS: Impaired osteogenic differentiation of Zmpste24-/- BMMSCs can be partly attributed to the decreased Cav 1.2 expression, which leads to the inhibition of canonical Wnt pathway. Bay K8644 treatment could be an applicable approach for treating age-related bone loss by ameliorating compromised osteogenic differentiation capacity through targeting Cav 1.2 channel.
- Are semi-automated software program designed for adults accurate for the identification of vertebral fractures in children? [Journal Article]
- EREur Radiol 2019 May 22
- CONCLUSIONS: AVERT™ has slightly higher accuracy but lower observer reliability for the representation of vertebral morphometry in children when compared with SpineAnalyzer™. However, neither software program is satisfactorily reliable for VF diagnosis in children.• SpineAnalyzer™ and AVERT™ have low diagnostic accuracy and observer agreement when compared to three paediatric radiologists' readings for the diagnosis of vertebral fractures (VF) in children. • Neither AVERT™ nor SpineAnalyzer™ is satisfactorily reliable for VF diagnosis in children. • Development of specific paediatric software and normative values (incorporating age-related physiological variation in children) is required.
- Circulatory pattern of cytokines, adipokines and bone markers in postmenopausal women with low BMD. [Journal Article]

This study aimed to investigate if hyperinsulinemia and/or insulin resistance was correlated with the occurrence of papillary thyroid cancer (PTC) in a group of Chinese patients. 258 inpatients were included in the study. According to the postoperative pathology results, all subjects were divided into PTC (n = 153) and control groups (with benign thyroid nodules, n = 105). Body mass index (BMI), fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), thyroid-stimulating hormone (TSH), FT4, FT3, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), serum uric acid (UA), and lipid levels. Fasting insulin levels, HOMA-IR values, TPOAb levels, serum TSH levels, and serum uric acid levels in the PTC group were higher than those in the control group (p < 0.05). However, no significant differences in age, gender, BMI, history of hypertension, and the levels of fasting plasma glucose, FT3, FT4, TGAb, total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein were observed between the two groups (p > 0.05). After the multiple logistic regression analysis, the occurrence of PTC was positively associated with fasting insulin (odds ratio [OR] = 1.048, 95% confidence interval [CI]: 1.003-1.096, p = 0.037) and TPOAb levels (OR = 1.001, 95% CI: 1.000-1.002, p = 0.032). Moreover, TPOAb level was positively correlated with vague margin (r = 0.126, p = 0.045) and negatively correlated with homogeneous echo (r = -0.179, p = 0.004). However, fasting insulin levels were not correlated with pathological characteristics of PTC. Hyperinsulinemia and higher TPOAb levels might be the risk factors of PTC, but not disease severity in Chinese patients.
