Author Interviews, Hip Fractures, Lipids / 20.01.2023

MedicalResearch.com Interview with: Dr Monira Hussain Senior Research Fellow & ECF Clinical Research Australian Fellow Public Health and Preventive Medicine Monash University Melbourne VIC MedicalResearch.com: What is the background for this study? Response:  25% of males and 44% of females aged 60 years or over experience minimal trauma fractures. Minimal trauma fractures are a clinical outcome of osteoporosis and may occur following little or no trauma i.e. fractures following a fall from standing height or less. Minimal trauma fractures are silent, people may not notice that they are at high risk of the disease until a bone is broken. I was aware of previous studies reporting that high-density lipoprotein cholesterol (HDL-C) was elevated in patients with osteoporosis. Two animal studies showing that HDL-C reduces bone mineral density by reducing osteoblast number and function provide a plausible explanation for why high HDL-C may increase the risk of fractures. Our study, the ASPirin in Reducing Events in the Elderly (ASPREE), and the ASPREE fracture substudy provide unique data that could determine whether these findings might apply to fracture risk in healthy older adults. The study collected data including HDL-C levels and fractures from more than 16,000 community-dwelling older adults. These participants were followed-up for a median of 4 years. (more…)
Author Interviews, Hip Fractures, Vegetarians / 21.08.2022

MedicalResearch.com Interview with: James Webster PhD Lead author Nutritional Epidemiology Group, University of Leeds MedicalResearch.com: What is the background for this study? Response: Hip fractures are the most severe consequence of osteoporosis and are a major public health problem. There are growing concerns of poor bone health and higher risk of fractures in vegetarians, but prospective studies comparing risk of hip fracture in vegetarians and meat-eaters over time are scarce and limited. A study of British men and women in the EPIC-Oxford cohort showed a greater risk of hip fracture in pescatarians, vegetarians, and vegans compared to meat-eaters. The only other study on the topic, the Adventist Health Study of US adults, found no clear evidence of a difference in hip fracture risk between vegetarians and meat-eaters, but identified hip fractures through questionnaires, which are susceptible to selective loss to follow-up. To build on previous research, we investigated the risk of hip fracture in occasional meat-eaters, pescatarians, and vegetarians compared to regular meat-eaters in middle-aged UK women, who are at a greater risk of hip fracture than men, with hip fractures accurately confirmed using objective and complete hospital records.

MedicalResearch.com Interview with: Meryl S. LeBoff, MD Chief, Calcium and Bone SectionDirector of the Skeletal Health and Osteoporosis CenterDirector, Bone Density UnitDistinguished Chair in Skeletal Health and Osteoporosis Professor of Medicine, Harvard Medical School Endocrinology, Diabetes and Hypertension, Women's Health Brigham And Women's Hospital JoAnn E. Manson, MD, DrPH Professor, Epidemiology, Harvard T.H. Chan School Of Public Health Michael and Lee Bell Professor of Women's Health, Medicine, Harvard Medical School Chief, Preventive Medicine, Brigham And Women's Hospital Co-Director, Womens Health, Brigham And Women's Hospital   MedicalResearch.com:  What is the background for this study?  What are the main findings? Response: Osteoporosis is a major public health problem. Although supplemental vitamin D has been widely used to reduce the risk of fractures in the general population, studies of the effects of vitamin D on fractures, the most important bone health outcome, have been conflicting. Randomized controlled trials, the highest quality studies, from around the world have shown benefit, no effect, or even harm of supplemental vitamin D on risk of fractures. Some of the trials used bolus dosing, had small samples sizes or short study duration, and co-administered calcium. No large RCTS of this scale tested whether daily supplemental vitamin D (without co-administration with calcium) prevented fractures in the US population. To fill these knowledge gaps, we tested the hypothesis in this ancillary study to VITAL, whether daily supplemental vitamin D3 reduced the risk of incident total, non-spine and hip fractures in women and men in the US.

MedicalResearch.com Interview with: Alison M. Cogan, PhD, OTR/L Polytrauma/TBI Advanced Fellow Washington DC VA Medical Center Washington DC MedicalResearch.com: What is the background for this study? Response: Medicare is shifting from a volume- to value-based payment for postacute care services, in which value is determined by patient characteristics and functional outcomes. Matching therapy time and length of stay (LOS) to patient needs is critical to optimize functional outcomes and manage costs. The objective of this study was to investigate the association among therapy time, LOS, and functional outcomes for patients following hip fracture surgery. This retrospective cohort study analyzed data on patients from 4 inpatient rehabilitation facilities and 7 skilled nursing facilities in the eastern and midwestern United States. Participants were patients aged 65 years or older who received inpatient rehabilitation services for hip fracture and had Medicare fee-for-service as their primary payer. We categorized patients into nine recovery groups based on low, medium, and high therapy minutes per day and low, medium, or high rate of functional gain per day. We measured the groups for functional mobility independence and self-care capabilities at the time each patient was discharged. (more…)

MedicalResearch.com Interview with: Jean Wactawski-Wende PhD Dean, SUNY Distinguished Professor Department of Epidemiology and Environmental Health School of Public Health and Health Professions University of Buffalo MedicalResearch.com: What is the background for this study? What are the main findings?  Response: This study included data from the Women’s Health Initiative, a prospective study of postmenopausal women from across the United States. We assessed physical activity in 77,206 women over an average of 14 years of follow-up. Approximately 1/3 of these women (average age 63.4 years) had at least one fracture occur. Higher physical activity levels were associated with  lower risk of hip and total fracture. Even levels of activity that were moderate, including regular walking and doing household chores, were beneficial.  (more…)

MedicalResearch.com Interview with: Kristine E. Ensrud MD MPH Professor of Medicine and Epidemiology and Community Health University of Minnesota Core Investigator, Center for Care Delivery and Outcomes Research Minneapolis VA Health Care System  MedicalResearch.com: What is the background for this study? Response: Women aged 80 years and older, a rapidly growing segment of the population, account for the majority of hip fractures in the United States. Hip fractures account for 72% of fracture-related health care expenditures and lead to significant morbidity and mortality. However, many late-life women at high risk of hip fracture are undiagnosed. Clinicians have difficulty identifying late-life women most likely to benefit from osteoporosis screening and interventions to prevent hip fracture in part due to concerns about comorbidity burden and prognosis in this patient population.

MedicalResearch.com Interview with: Prof. Haakon E Meyer, PhD Department of Public Health and Global Health Norwegian Institute of Public Health Oslo, Norway MedicalResearch.com: What is the background for this study? What are the main findings? Response: The use of high dose vitamin supplementation is popular in parts of the population, often without any clear indication and in the absence of clear evidence of benefit. However, side effects can occur, and in a previous published secondary analysis of double blinded randomized controlled trials, we found to our surprise an increased risk of hip fracture in those supplemented with high doses of vitamin B6 in combination with vitamin B12. This finding was re-assessed in the current study employing data from the large observational Nurses' Health Study. As in the previous study, we found that a combined high intake of vitamin B6 and B12 was associated with increased risk of hip fracture. (more…)

MedicalResearch.com Interview with: Prof. Gillian Mead Chair of Stroke and Elderly Care Medicine Prof. Martin Dennis Chair of Stroke Medicine Centre for Clinical Brain Sciences The University of Edinburgh   MedicalResearch.com: What is the background for this study? Response: We are both practicing stroke physicians as well as clinical trialists. Therefore our interest in this area was triggered by the exciting results of the FLAME trial in 2011. This appeared to indicate that fluoxetine might boost the recovery of stroke patients. Potentially this was very important given the increasing numbers of people having disability due to stroke, and the fact that fluoxetine is inexpensive and could be introduced very easily into clinical practice. We were further encouraged by the large numbers of small RCTs we identified when we carried out a Cochrane systematic review on the topic. These trials provided more evidence of potential benefit but there was evidence that trials of greater quality showed less benefit, and benefits were greater in patients who were depressed. We felt there was a need for more evidence derived from much larger numbers of patients. (more…)

MedicalResearch.com Interview with: “Just a hairline fracture...” by Gloria Bell is licensed under CC BY 2.0Brittany Bindon, MD Department of Internal Medicine University of Chicago Chicago, Illinois MedicalResearch.com: What is the background for this study? Response: Bisphosphonates are commonly used in the treatment of osteoporosis, however, they have been associated with rare, severe side effects such as osteonecrosis of the jaw and atypical femoral fractures. As a result, bisphosphonate drug holidays have become common in clinical practice though currently, there are minimal data on the safe duration of these drug holidays. We sought to further characterize the clinical and laboratory parameters associated with increased fracture risk in patients on bisphosphonate drug holiday. (more…)

MedicalResearch.com Interview with: Dr Setor Kunutsor Ba(Legon), MBChB(Legon), MA(Cantab), PhD(Cantab) Research Fellow Musculoskeletal Research Unit University of Bristol MedicalResearch.com: What is the background for this study? Response: Bone fractures are one of the leading causes of disability and ill health especially among the ageing population and are a burden to health care systems. There is established evidence that calcium and vitamin D play an important role in bone health. Magnesium is an essential trace element, being the second most abundant intracellular cation after potassium and the fourth most abundant cation in the body. It serves several important functions in the body, which include protein synthesis, nucleic acid synthesis, enzymatic reactions, and has also been shown to be cardio-protective. It is also an important component of bone, with majority (67 percent) of total body magnesium known to be found in the bone tissue. There have been suggestions from both human and animal experiments that magnesium may have a beneficial effect on bone health; however, its relationship with fractures is not very certain. (more…)
Author Interviews, Hip Fractures, NYU, Orthopedics / 09.02.2017

MedicalResearch.com Interview with: Afshin E. Razi MD Clinical Assistant Professor NYU Hospital for Joint Diseases Department of Orthopaedic Surgery New York, N.Y. 10016 MedicalResearch.com: What is the background for this study? What are the main findings? Response: We did an extensive literature search and through our two previous seminars on this topic we were able to gather information to aid our colleagues on best ways of differentiating causes of hip and back pain. As an orthopaedic surgeon specializing in spine surgery I encounter many patients who present with concomitant back and hip pain. Many of these patients are also referred to me by surgeons who solely take care of hip problems such as total hip replacement or sport medicine specialist who treat younger patients with hip pain. It can be very difficult to properly diagnose the main issue and as such some patients go on to have unnecessary treatments, including surgery, because of their persistent symptoms. It was our goal to try to educate physicians, including orthopaedic surgeons, on the common differential diagnoses, appropriate clinical history and physical examination, diagnostic tools and their evaluations appropriately, as well as treatment options and priorities of which one to be treated first. More recently, it has been noted that some patients who have undergone total hip replacement with significant curvature of the spine had postoperative dislocation of the hip after reconstruction of the spinal malalignment. This article also talks about this newly seen problem. (more…)

MedicalResearch.com Interview with: Ann L. Gruber-Baldini, Ph.D. Professor, Division of Gerontology Director, Program in Epidemiology and Human Genetics Department of Epidemiology & Public Health University of Maryland School of Medicine  MedicalResearch.com: What is the background for this study? Response: While men make up only about 25% of all hip fractures, the number of men who fracture their hip is increasing and we know men are more likely to die than women after a hip fracture. It is also known that those with cognitive impairments, typically due to delirium and Alzheimer's disease and related dementia, are more likely to do more poorly after the fracture. The impact of both sex and cognition on outcomes after hip fracture has not been fully explored. (more…)
Aging, Author Interviews, Depression, Geriatrics, Hip Fractures / 16.01.2017

MedicalResearch.com Interview with: Sanna Torvinen-Kiiskinen MSc (Pharm.), PhD student, Kuopio Research Centre of Geriatric Care and School of Pharmacy University of Eastern Finland MedicalResearch.com: What is the background for this study? Response: Antidepressants are widely used among elderly persons, especially persons with Alzheimer’s disease. They are used not only for treatment for major depression, but for treatment of anxiety, insomnia and chronic pain as well as behavioral symptoms caused by dementia. However, antidepressants, as well as other psychotropic drugs, may cause sedation, confusion, orthostatic hypotension and hyponatremia, which increase the risk of falling and fractures. Because of changes in pharmacodynamics and pharmacokinetics due to aging, older persons are at the higher risk of those adverse events. The aim of our study was to investigate whether antidepressant use is associated with an increased risk of hip fracture among community-dwelling persons with and without Alzheimer’s disease. (more…)

MedicalResearch.com Interview with: Tom Withers Research Student, School of Health Sciences University East Anglia Norwich, UK MedicalResearch.com: What is the background for this study? What are the main findings? Response: There is a lot of subjective evidence to suggest that physical activity does not improve following hip replacement we wanted to therefore synthesise the current evidence to come to a more objective conclusion. The main finding from this study is that physical activity does not significantly change pre-operatively compared to up to one year post-operatively. (more…)

MedicalResearch.com Interview with: Jeffrey Munson, MD, MSCE Assistant Professor The Dartmouth Institute for Health Policy & Clinical Practice Assistant Professor, Department of Medicine Geisel School of Medicine at Dartmouth MedicalResearch.com: What is the background for this study?  Response: Fragility fractures due to osteoporosis are a common and costly event among older Americans. Patients who experience one fragility fracture are at increased risk to have a second fracture. Our group is interested in exploring ways in which the risk of a second fracture could be reduced. In this paper, we studied prescription drug use both before and after fracture. We know many prescription drugs have been shown to increase the risk of fracture, but we don’t know whether doctors try to reduce the use of these drugs after a fracture has occurred. Our study was designed to answer this question. (more…)
Author Interviews, Bone Density, Endocrinology, Hip Fractures, Pharmacology / 08.04.2016

MedicalResearch.com Interview with: Bente Langdahl Professor, Consultant, PhD, DMSc Department of Endocrinology and Internal Medicine THG Aarhus University Hospital Aarhus Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Romosozumab is a humanised antibody against sclerostin currently in development for the treatment of osteoporosis. Romosozumab has a dual effect on bone; it stimulates bone formation and inhibits bone resorption. If this new treatment obtains regulatory approval and becomes available for the treatment of osteoporosis, some of the patients who will be candidates for this new treatment will already have been treated with other available treatments, for example, bisphosphonates. This study compared the effects of romosozumab and teriparatide, a currently available bone forming treatment, on bone mass, bone structure and bone strength. The results showed that the percent change from baseline in BMD at the total hip through month 12 (the primary endpoint) was significantly greater with romosozumab compared with teriparatide: 2.6 percent versus –0.6 percent, respectively (p<0.0001). For the secondary endpoints; lumbar spine BMD by DXA, total hip and femoral neck BMD by DXA and QCT and bone strength estimated by finite element analysis patients treated with romosozumab had significantly larger increases from baseline compared with those taking teriparatide, with mean differences ranging from 3.1 percent to 4.6 percent (all p-values <0.0001).

Author Interviews, Frailty, Hip Fractures, Parkinson's, PLoS / 08.02.2016

MedicalResearch.com Interview with: Helena Nyström MD, PhD Candidate Department of Community Medicine and Rehabilitation Umeå University Umeå, Sweden Medical Research: What is the background for this study? Response: Parkinson’s disease (PD) has an insidious onset and the prodromal phase, preceding the onset of the characteristic PD symptoms, may last for decades. Most prodromal signs previously reported are of non-motor type, such as sleep and mood disorders. However, recent studies have reported balance problems and an increased risk of accidental injuries in the last 3-5 years before diagnosis of Parkinson’s disease , and in a previous study we found a lower muscle strength at military conscription in men who were diagnosed with  Parkinson’s disease three decades later. In this study, we aimed to investigate if such subtle strength deficits may translate into an increased risk of fall-related injuries. Medical Research: What are the main findings? Response: The median study time was 20 years before the diagnosis of  Parkinson’s disease , and during this time more individuals with PD (18%) than controls (11.5%) had at least one fall-related injury. The risk was most increased in the last few years before the diagnosis of  Parkinson’s disease , but a difference between the groups appeared already a decade before the PD diagnosis. The risk of hip fracture was increased during the entire study time of 26 years before the diagnosis of Parkinson’s disease . (more…)
Author Interviews, Hip Fractures, Medical Imaging, Osteoporosis / 25.01.2016

MedicalResearch.com Interview with: Margaret L. Gourlay, MD, MPH Assistant Professor UNC Department of Family Medicine Chapel Hill, NC 27599-7595 Medical Research: What is the background for this study? What are the main findings? Dr. Gourlay: While clinical practice guidelines universally recommend bone density screening for fracture prevention in women aged 65 years and older, minimal data exist to guide bone density screening in older men. We studied how often bone density screening tests should be ordered in men, using data from the Osteoporotic Fractures in Men (MrOS) Study. MrOS is the largest and longest-running (since 2000) US study of bone density and fracture in men aged 65 and older. After peak bone mass is reached in young adulthood, both men and women lose bone density as they get older. Based on our earlier findings in older women, we expected that men aged 65 and older with higher bone density T-score measurements (T-score >-1.50) on a first (baseline) bone density test would have a substantially longer estimated time to develop the lowest level of bone density (osteoporosis) than men with better baseline measurements. Clinicians want to know the time to osteoporosis because they prescribe osteoporosis treatments to prevent future fractures in elderly patients. As expected, we found that the men with higher baseline bone density had a much slower transition to osteoporosis compared to men with lower bone density. In fact, only nine out of 4203 (0.2%) of men with higher baseline bone density developed osteoporosis after an average of 8.7 years of bone density follow-up. That was much lower than we expected and is good news for men who have favorable scores on their first bone density test. Men who had lower baseline bone density measurements developed osteoporosis faster. Unfortunately, maintaining bone density above the osteoporosis range did not guarantee that men remained fracture-free.   Most of the major osteoporotic fractures (broken hip, spine, wrist or upper arm/shoulder) occurred in men who did not have osteoporosis. This might be because they had accidents or injuries that broke their bones despite their bone density being above the thinnest range. (more…)
Author Interviews, Hip Fractures, JAMA, Menopause, Osteoporosis, Vitamin D / 05.08.2015

MedicalResearch.com Interview with: Karen E. Hansen, M.D., M.S. Associate Professor of Medicine University of Wisconsin School of Medicine and Public Health Madison, WI 53705-2281 Medical Research: What is the background for this study? Dr. Hansen: The USPTF says to older community dwelling adults, "don't bother taking vitamin D", the Endocrine Society says "take 2,000-4,000 IU daily" and the Institute of Medicine gave an RDA of 600-800 IU daily. The Endocrine Society argues that optimal vitamin D levels are 30 ng/mL and higher, while the Institute of Medicine concludes that 20 ng/mL and higher indicates optimal vitamin D status. The disagreement between experts prompted my study. Medical Research: What are the main findings? Dr. Hansen: Among postmenopausal women whose vitamin D level was ~21 ng/mL at baseline, there was no benefit of high-dose or low-dose vitamin D, compared to placebo, on spine/hip/total body bone mineral density, muscle fitness by 5 sit to stand test or Timed Up and Go, or falls. We did see a small 1% increase in calcium absorption in the high-dose vitamin arm, but this small increase did not translate into clinically meaningful changes in bone density or muscle tests.

Monique Bethel, MD Subspecialty Service, Department of Veterans Affairs Medical Center, Department of Medicine, Section of Rheumatology Georgia Regents University Augusta, GAMedicalResearch.com Interview with: Monique Bethel, MD Subspecialty Service, Department of Veterans Affairs Medical Center, Department of Medicine, Section of Rheumatology Georgia Regents University Augusta, GA MedicalResearch: What is the background for this study? Dr. Bethel: Osteoporosis and kidney stones share several risk factors, including elevated calcium in the urine (hypercalciuria), low potassium intake, and possibly, diets high in sodium. Accordingly, several studies have shown a significant relationship between kidney stones and osteoporosis in men. However, it is unclear if this relationship is also true for women. Previous studies examining this association have been small and inconclusive.   With the Women’s Health Initiative, we had data available from approximately 150,000 postmenopausal women in the US. Using this database, we were able to study the relationship between kidney stones and changes in bone mineral density and fractures. MedicalResearch: What are the main findings? Dr. Bethel: We found no association between the presence of kidney stones and changes in bone mineral density over time at the hip, lumbar spine, or the whole body. Also, there was no association between the presence of kidney stones and fractures. We also found that 14% of women who had a history of kidney stones upon entering the studies had another one occur during the course of the study (approximately 8 years). (more…)
Author Interviews, Geriatrics, Hip Fractures, Lancet / 06.02.2015

Ingvild Saltvedt PhD Department of Neuroscience, Norwegian University of Science and Technology, Medical Faculty Trondheim, Norway MedicalResearch.com Interview with: Ingvild Saltvedt PhD Department of Neuroscience, Norwegian University of Science and Technology, Medical Faculty Trondheim, Norway Medical Research: What is the background for this study? What are the main findings? Dr. Saltvedt: Hip fracture patients are often old, frail and have many comorbidities. When treated with a traditional orthopaedic approach the outcomes are often poor, and many patients get functionally impaired with reduced ability to walk independently and impairment in daily life activities and with high costs for the society.  In many ways these patients are geriatric patients with hip-fractures. It has previously been shown that acutely sick geriatric patients benefit from treatment in geriatric wards and different kind of  orthogeriatric treatment models where orthopaedic surgeons and geriatricians collaborate have been studied and have shown beneficial results on short term outcomes. In the present study patients home-dwelling hip-fracture patients were randomised to orthogeriatric treatment or traditional orthopaedic treatment from admission to the hospital and during the entire stay except for the surgery that was performed similar in both groups. The study focused on long-term outcomes and also on use of health care services and cost-effectiveness.  Patients in the orthogeriatric group got comprehensive geriatric assessment and treatment performed by an interdisciplinary team that emphasised early mobilisation and rehabilitation and started discharge planning early. In the orthopaedic group traditional treatment according to national and international guidelines was offered. The primary endpoint was mobility at four months, that was better in the orthogeriatric group than in the orthopaedic group, the same difference was also shown at 12 months. In addition there were differences in instrumental activities of daily living and personal activities of daily living, quality of life and fear of falling, all differences were statistically and clinically significant and in favour of the orthoegeriatric group. The length of hospital stay was 1,7 days longer in the geriatric group, while there was no differences in days spent in hospital during one year of follow-up. One of four orthogeriatric patients were discharged directly home as compared to one of ten in the orthopaedic group. The orthopaedic group spent more days in nursing homes and rehabilitation institutions during one year of follow-up. The treatment was cost-effective in favour of the orthogeriatric group. (more…)

Department of Orthopaedics, Oslo University Hospital / NIMI / Norwegian School of Sports Sciences MedicalResearch.com: What are the main findings of the study? Answer: The main finding of the study was that exercise therapy in addition to patient education resulted in significantly higher 6-year cumulative survival of the native hip to total hip replacement compared with patient education only. Over the 6 year follow-up period the need for total hip replacement was reduced by 44% in the group who received both exercise therpay and patient education. Also, better self-reported physical function was demonstrated in the group who received exercise therapy and patient education, suggesting that the lower surgery rate in this group were due to better hip function, with or without the presence of pain.

MedicalResearch.com Interview with: Stefano Volpato MD MPH Department of Medical Sciences, University of Ferrara Ferrara, Italy MedicalResearch.com: What are the main findings of the study? Dr. Volpato: In this study we evaluated clinical value of handgrip strength  assessment in older patients admitted to the hospital for hip fracture. We observed 504 older patients admitted to 4 Italian hospitals for hip surgery, able of walking independently before fracture, and we found a strong, graded and independent association of grip strength, assessed before hip surgery, and the likelihood of functional recovery over the one-year follow-up. The findings reported in our manuscript can be summarized as: a. handgrip strength significantly correlated with several prognostic factors traditionally considered in clinical practice, such as age, gender, neuro-psychological and functional status, comorbidity level, vitamin D plasma levels, and time before the surgical procedure; b. logistic regression models showed that handgrip strength was directly associated with higher probability of walking recovery, both at any follow-up (incident walking recovery), and for at least 2 consecutive follow-ups (persistent walking recovery); b. Kaplan-Meier survival estimates showed that lower grip strength was related to increased mortality after hip surgery; c. the association between grip performance and walking recovery was clinically relevant and statistically independent of potential confounders.

Nguyen Osteoporosis and Bone Biology Program Garvan Institute of Medical Research 384 Victoria Street, Darlinghurst NSW 2010 Australia MedicalResearch.com: What are the main findings of the study? Dr. Nguyen: We analyzed polymorphisms of the FTO (fat mass and obesity) gene in 934 elderly women of Caucasian background, and found that carriers of minor genotype (AA) of the SNP rs1121980 had a two-fold increase in the risk of hip fracture compared with carriers of major genotype (GG). Approximately 20% of women are carriers of the AA genotype. We estimate that about 17% of hip fracture cases could be attributed to the variation within the gene. (more…)
