What is the prevalence and significance of osteoporosis in US women? Response: Osteoporosis is widely prevalent and is increasing in prevalence not only in the US but also around the world. 10.2 million Americans have osteoporosis and that an additional 43.4 million have low bone mass. More than 2 million osteoporosis-related fractures occur annually in the US, more than 70% of these occur in women ( from National Osteoporosis Foundation (NOF) estimates).

MedicalResearch.com Interview with: [caption id="attachment_29169" align="alignleft" width="200"]Rachel H. Farr, Ph.D. Assistant Professor Department of Psychology University of Kentucky Dr. Rachel H. Farr[/caption] Rachel H. Farr, Ph.D. Assistant Professor Department of Psychology University of Kentucky MedicalResearch.com: What is the background for this study? Response: Controversy continues to surround parenting by lesbian and gay (LG) adults and outcomes for their children. As sexual minority parents increasingly adopt children, longitudinal research about child development, parenting, and family relationships is crucial for informing such debates. This longitudinal study compared outcomes for children, parents, couples, and the overall family system among nearly 100 (N = 96) adoptive families with lesbian, gay, and heterosexual parents at two time points: when children were preschool-age, and approximately 5 years later, when children were in middle childhood. Child outcomes were assessed via parent- and teacher-reported behavior problems, while parent outcomes were assessed via self-reports of parenting stress levels. Couple and family outcomes were evaluated by parent reports of couple adjustment and overall family functioning.

What are the main findings? Response: We know that opportunistic brief interventions by physicians can be effective, but there is no evidence that they are so for obesity. Physicians worry that broaching this topic will be offensive, time-consuming, and ineffective. We needed a randomised trial to assess whether physicians’ fears were justified, or in fact brief interventions could be as effective for patients who are overweight as they are for smoking or problem drinking and that’s what we did.

What are the main findings? Response: Historically, patient perceptions of surgeon reimbursement have been exaggerated compared with actual reimbursement. Currently there has been an increased focus or reducing health care cost, increasing access to health care and a shift to tie Medicare and insurance reimbursement to quality outcomes. Among these changes was the reduction in reimbursement payments for orthopedic surgeons. When we polled over 200 of our clinic patients, we found that most patients don’t think an orthopedic surgeon is overpaid but they greatly exaggerate how much a surgeon is reimbursed by Medicare for performing knee surgery. When told of the reimbursement payments, patients found them too be low and said they would be willing to pay more out-of-pocket costs. Patients also believe a surgeon should be compensated more for having fellowship training. • Nearly 90 percent of patients say physicians are not overpaid and their salaries should not be cut. • 61 percent of patients say a surgeon’s salary should not be tied to outcomes. • 79 percent of patients say reimbursement to drug and device companies should be reduced.

What are the main findings? Response: The study is a follow-up of a treatment trial on which we have previous reported. In the original Preschool Autism Communication Trial (PACT), 152 children aged 2-4 with autism were randomised to receive the 12 month early intervention or treatment as usual. The type of early intervention used in this study focuses specifically on working with parents. Through watching videos of themselves interacting with their child and receiving feedback from therapists, parents are able to enhance their awareness and response to their child’s unusual patterns of communication; they become better able to understand their child and communicate back appropriately in a focused way. Parents take part in 12 therapy sessions over 6 months, followed by monthly support sessions for the next 6 months. In addition, parents agree to do 20-30 minutes per day of planned communication and play activities with the child. The study published today is the follow-up analysis of the same children approximately 6 years after the end of treatment. The main findings are that children who had received the PACT intervention aged 2-4 had less severe overall symptoms six years later, compared to children who only received ’treatment as usual’ (TAU) with improved social communication and reduced repetitive behaviours, although no changes were seen in other areas such as language or anxiety. These findings on an international recognised and blind rated observational measure of autism symptoms were accompanied by improvements in children’s communication with their parents for the intervention group, but no differences in the language scores of children. Additionally, parents in the intervention group reported improvements in peer relationships, social communication and repetitive behaviours. However, there was no significant difference between the two groups on measures of child anxiety, challenging behaviours (eg, conduct/oppositional disorder) or depression.
Allergies, Author Interviews, NIH / 26.10.2016

What are the main findings? Response: While allergic disease is a wide spread problem, it is actually a select few proteins, called allergens, that initiate allergy symptoms. This study was focused on looking for fundamental biochemical differences between allergens and non-allergens derived from the house dust mite. We found that the mite allergens, as a group, are distinctly different from the non-allergens in that they are more highly produced, and more stable. Previous anecdotal evidence suggested that these properties would lead to more allergens surviving the journey from the source (either mites or pollens) to a person. In addition, the greater stability of allergens may influence the decision making of the immune system to target these proteins as dangerous instead of harmless.

MedicalResearch.com Interview with: [caption id="attachment_29144" align="alignleft" width="169"]Ann Kurth, Ph.D., C.N.M., R.N. USPSTF Task Force member Dean of the Yale School of Nursing Dr. Ann Kurth[/caption] Ann Kurth, Ph.D., C.N.M., R.N. USPSTF Task Force member Dean of the Yale School of Nursing MedicalResearch.com: What is the background for this study? What are the main findings? Response: Breastfeeding is beneficial for both mothers and their babies, with the evidence showing that babies who are breastfed are less likely to get infections such as ear infections, or to develop chronic conditions such as asthma, obesity, and diabetes. For mothers, breastfeeding is associated with a lower risk for breast and ovarian cancer and type 2 diabetes. While breastfeeding rates have been rising in recent decades—with 80 percent of women starting to breastfeed and just over half still doing so at six months—they are still lower than the Healthy People 2020 targets and the Task Force wanted to review the latest evidence around how clinicians can best support breastfeeding.” After balancing the potential benefits and harms, the Task Force found sufficient evidence to continue to recommend interventions during pregnancy and after birth to support breastfeeding. This recommendation includes the same types of interventions the Task Force recommended in 2008, such as education about the benefits of breastfeeding, guidance and encouragement, and practical help for how to breastfeed.

MedicalResearch.com: What is the background for this study? What are the main findings? Response: SPD489-346, designed as a multi-center, double-blind, placebo-controlled, dose-optimized, randomized-withdrawal study, is the first-ever longer-term pharmacologic study (38 weeks) to evaluate the maintenance of efficacy between Vyvanse and placebo in adults with moderate to severe binge eating disorder (B.E.D.). Study SPD489-346 evaluated the longer-term maintenance of efficacy (38 weeks) between Vyvanse and placebo based on the primary endpoint of time to relapse during the randomized-withdrawal phase in adults aged 18 to 55 (N=267) with moderate to severe B.E.D. based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition – Text Revision (DSM-IV-TR®) criteria. In the study, relapse was defined as having two or more binge days per week for two consecutive weeks prior to any visit and an increase in Clinical Global Impressions-Severity (CGI-S) score of two or more points relative to the randomized-withdrawal baseline visit Results from SPD489-346 indicated that Vyvanse (n=136) demonstrated significant maintenance of efficacy compared to placebo (n=131) based upon the primary endpoint of time to relapse. At the conclusion of the study, maintenance of efficacy for patients who had an initial response during the open-label phase, and then continued on Vyvanse during the randomized-withdrawal phase, was demonstrated with Vyvanse being superior over placebo as measured by time to relapse. Safety and tolerability evaluations of Vyvanse included treatment-emergent adverse events (TEAEs) and vital signs. The safety profile for Vyvanse in this study was generally consistent with the known profile reported in previous studies in adult patients with moderate to severe B.E.D. Vyvanse is indicated for the treatment of moderate to severe B.E.D. in adults. Vyvanse is not for weight loss. It is not known if Vyvanse is safe and effective for the treatment of obesity. Vyvanse is a federally controlled substance (CII) because it can be abused or lead to dependence. Keep in a safe place to prevent misuse and abuse. Selling or sharing Vyvanse may harm others and is illegal.

MedicalResearch.com Interview with: [caption id="attachment_29061" align="alignleft" width="165"]Dr. Jeri Nieves PhD Director of bone density testing New York's Helen Hayes Hospital Dr. Jeri Nieves[/caption] Dr. Jeri Nieves PhD Director of bone density testing New York's Helen Hayes Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Amyotrophic lateral sclerosis (ALS) is a devastating severe neurodegenerative disorder that causes progressive muscle atrophy, paralyses, and eventual respiratory failure. Our objective was to evaluate the associations between nutrition and severity of ALS around the time of diagnosis. This was a cross-sectional analysis of data from a multicenter cohort of 302 patients with ALS. We assessed nutrient intake using a modified Block Food Frequency Questionnaire. The outcomes were respiratory function (measured using percentage forced vital capacity; FVC%) and functional performance measured by ALS Functional Rating Scale–Revised (ALSFRS-R), both considered important indicators of the severity of ALS. Results of the regression analysis were that higher intakes of antioxidants and carotenes from vegetable intake were associated with higher ALSFRS-R scores or better %FVC. We used a novel analysis to evaluate the diet as a whole and found that higher intakes of antioxidants, fiber from grains, vegetables, fruit, eggs, fish, and poultry were all associated with higher function in patients with ALS. However, milk and lunch meats were associated with lower measures of function. These consistent results from two different statistical analyses indicate that diet may help minimize the severity of ALS. Perhaps these findings point to the role of oxidative stress in ALS severity. In summary, increased consumption of antioxidant nutrients, foods high in carotenoids and fiber, vegetables and fruits, poultry and fish are associated with better function around the time of ALS diagnosis.
Author Interviews, Dermatology, JAMA / 26.10.2016

MedicalResearch.com Interview with: Aaron S. Farberg, MD Department of Dermatology Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Regular sunscreen use is a critical component of sun protection and has been shown to reduce skin cancer risk. However, there have often been conflicting sunscreen messages (sometimes without scientific support) that have led to confusion by the public. Controversy has also emerged surrounding the safety and possibility of adverse effects from various sunscreen ingredients. The purpose of this study was to determine US dermatologists’ actual sunscreen perceptions, potential safety concerns as well as their recommendations and personal usage. Some people are so affected by the sun that they require a brand of Custom Sunscreens to help protect them from the sun. Our study found that dermatologists have an overall positive view of sunscreen. 97% of dermatologists agree that regular sunscreen use helps lower skin cancer risk, 100% agree that it reduces subsequent photoaging, and 99% recommend their family/friends use sunscreen. Nearly all (96%) consider FDA approved sunscreens currently available in the US to be safe and (99%) believe their patients generally under-apply sunscreen.

MedicalResearch.com Interview with: [caption id="attachment_29187" align="alignleft" width="150"]Yunru Huang Ph.D. Candidate in epidemiology Department of Pediatrics University of California Davis, Sacramento, CA Yunru Huang and Dr. James Marcin (left)[/caption] Yunru Huang Ph.D. Candidate in epidemiology Department of Pediatrics University of California Davis, Sacramento, CA MedicalResearch.com: What is the background for this study? Response: Each year, more than 27 million children seek care in emergency departments (EDs) in the United States. Many EDs, however, are not fully equipped with the recommended pediatric supplies and may not have access to the pediatric specialists and resources needed to provide definitive care. As a result, many children receiving treatment in EDs of hospitals with limited pediatric resources are transferred to another hospital’s ED or inpatient unit for admission. The Emergency Medical Treatment and Active Labor Act (EMTALA) requires hospitals to make decisions on patient transfer and admission independent of insurance status. That is, the decision to transfer a patient to another hospital for admission should only depend upon clinical factors or the need for specialty services. However, patterns observed in the medical literatures have suggested that a child’s insurance status could be associated with transfer and admission decisions. These studies have been limited to single institutions and/or have been limited to specific conditions._ENREF_14 Whether or not transfer decisions among pediatric patients are related to insurance status has yet to be studied on a national level and across a variety of diagnoses. We used Healthcare Cost and Utilization Project 2012 Nationwide Emergency Department Sample data and sought to investigate the relationships between insurance status and odds of transfer relative to local admission among pediatric patients receiving care in the ED.

MedicalResearch.com Interview with: [caption id="attachment_29117" align="alignleft" width="150"]Jason Busse PhD Associate Professor, Department of Anesthesia McMaster University Hamilton, ON Jason Busse[/caption] Jason Busse PhD Associate Professor, Department of Anesthesia McMaster University Hamilton, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our group previously reviewed the evidence regarding the effectiveness of low-intensity pulsed ultrasound (LIPUS) for fracture healing. We found moderate to very low quality evidence for LIPUS in accelerating functional recovery among patients with fracture, and that most trials only explored effects on surrogate outcomes (e.g. radiographic healing); only five of 13 trials directly assessed functional end points - of these, one was positive. We concluded that large trials of high methodological quality, focusing on patient important outcomes such as quality of life and return to function, were needed to establish the role of LIPUS in fracture healing. We have now completed such a study. Our large, international trial of LIPUS for surgically managed tibial fractures found the addition of LIPUS does not improve functional recovery or accelerate radiographic healing.

Simopoulos, M.D. FACN President, The Center for Genetics Nutrition and Health Washington, DC 20016 MedicalResearch.com: What is the background for this study? What are the main findings? Response: I have written extensively on the evolutionary aspects of diet, the diet of Crete prior to 1960 in which I pointed to the misinterpretation of the data of the Seven Countries Study by Keys et al. A major characteristic of these diets is a balanced omega-6/omega-3 ratio. The recommendation to substitute saturated fats with omega-6 rich oils (sunflower, corn, soybean) increases inflammation and coronary heart disease. It has been shown in a number of studies that a high omega-6/omega-3 (20/1 instead of a balanced ratio) leads to an increase in white adipose tissue and prevents the formation of brown adipose tissue leading to obesity. The changes in the diet-high in omega-6 oils depletion of omega-3 and high fructose along with highly refined carbohydrates in processed foods and a sedentary lifestyle lead to obesity, diabetes, coronary heart disease and cancer. The scientific evidence from the FAT-1 mouse and recent cohort studies clearly show that the current dietary guidelines as the previous ones are not based on science that takes into consideration genetics, metabolism, the concept that a calorie is not a calorie. It is important to consider that nutrients influence the expression of genes, the omega-6 fatty acids are the most pro-inflammatory nutrients, and inflammation is at the base of all chronic non-communicable diseases.

MedicalResearch.com Interview with: Dr. Richard Dutton, MD Chief quality officer U.S. Anesthesia Partners Dallas MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to document the change in national anesthesia practice over the past 5 years, specifically the increase in non-operating room anesthesia NORA. We found that non-operating room anesthesia now accounts for more than 1/3 of all anesthetics. The proportion continues to rise as minimally invasive procedures are developed in gastroenterology, cardiology, radiology and other non-surgical disciplines. These procedures are often performed in complex patients, and require anesthesia involvement to facilitate.

Kapp, MPH, PhD, FACE Associate Professor 2014 Baldrige Executive Fellow University of Missouri School of Medicine Department of Health Management and Informatics Columbia, MO 65212 MedicalResearch.com: What is the background for this study? What are the main findings? Response: The United States lags behind its high-income peer countries on a number of critical health outcomes, including life expectancy, and this gap has been widening for the last several decades. The 2010 Patient Protection and Affordable Care Act (ACA) created a number of provisions to try to address this, including an emphasis on a systems-engineering approach to health care services. In addition to the ACA, there is a growing movement toward collective impact among community-based organizations. However, despite this focus, U.S. health and health care activities are often uncoordinated and fragmented. We applied a systems-thinking approach to U.S. population health. We used the Malcolm Baldrige Framework for Performance Excellence as the unifying conceptual systems-thinking approach. In addition to this proposed framework, we make two critical recommendations: 1) the need to drive a strategic outcomes-oriented, rather than action-oriented, approach by creating an evidence-based national reporting dashboard; and 2) improve the operational effectiveness of the workforce.

Joannie Lortet-Tieulent[/caption] Joannie Lortet-Tieulent MSc Senior Epidemiologist American Cancer Society, Inc. Atlanta, GA 30303 MedicalResearch.com: What is the background for this study? Response: Many tobacco control policies are decided at state level. We have known for some times that some states have pioneered tobacco control, or have implemented strong tobacco control or programs. Meanwhile, in other states, tobacco control and programs can be weaker. Also, some states have large populations with low socioeconomic status, among which smoking prevalence is higher. We were interested in how those state-level differences impact people’s health.

Chan School of Public Health Boston, MA 02115 Dr. Anna D. Sinaiko[/caption] Anna D. Sinaiko, PhD, MPP Research Scientist Department of Health Policy & Management Harvard T.H. Chan School of Public Health Boston, MA 02115 MedicalResearch.com: What is the background for this study? What are the main findings? Response: One strategy for reducing health care spending in the U.S. is to increase transparency in health care pricing for patients. The idea is that patients can learn about and anticipate the prices they would pay for health care before they receive care, and incorporate that information into their choices about whether and where to receive care. When patients incorporate price information into their decisions, it gives providers an incentive to compete on price and quality. There has been a dramatic increase in the availability of health care price information over the last few years for patients who have commercial health insurance, primarily through web-based tools. In this study, we examined the impact of this information on patient choice of health care facility. We find that a small number of enrollees with commercial health insurance through Aetna, 3% overall, accessed price information through their transparency tool. Among users of the tool, patients who viewed price information for imaging services and for sleep studies before they had the service chose facilities with lower prices, and incurred lower spending (of 12%) for imaging services. We found no effect on patient choices for patients who viewed price information for 6 other health care services (carpal tunnel release, cataract/lens procedures, colonoscopy, echocardiogram, mammograms, and upper gastrointestinal endoscopy).

Response: Concussion remains a major public health concern in children. Approximately 30% of affected children experience persistent post-concussive symptoms (PPCS) for at least one month post-injury. These symptoms may negatively impact their health related quality of life. Examples may include cognition, memory and attention affecting school attendance and performance, mood and social engagement, as well as physical performance. Prior to this study, there was little evidence that examined the relationship between PPCS and quality of life following concussion. This was important to better understand in order to provide appropriate interventions, expectation management and ultimately a better standard of care to affected patients and their families.
Author Interviews, Columbia, JAMA, OBGYNE, Stroke / 24.10.2016

MedicalResearch.com Interview with: Eliza Miller, M.D. Vascular Neurology Fellow New York-Presbyterian Hospital/Columbia University Medical Center We collaborated with researchers at the Massachusetts General Hospital and with the New York State Department of Health. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Prior research has found that older women of childbearing age are at higher risk of stroke during pregnancy and postpartum than younger women. We hypothesized that their increased stroke risk might not be due to pregnancy-related factors, but just due to the fact that stroke risk increases with age for all people. We used billing data from New York State hospitals to calculate incidence risk ratios for four age groups: 12-24, 25-34, 35-44 and 45-55. In each age group, we compared the incidence of stroke in women who were pregnant or postpartum to the incidence of stroke in women of the same age who were not pregnant. As in prior studies, we found that the incidence of pregnancy-associated stroke was higher in older women compared to younger women (about 47/100,000 deliveries in the oldest group, versus 14/100,000 deliveries in the youngest group). However, the incidence ratios showed that pregnancy increased stroke risk significantly in women under 35, but did not appear to increase stroke risk in women over 35. In the youngest group (age 12-24), pregnancy more than doubled the risk of stroke, and in the 25-34 age group, pregnancy increased stroke risk by 60%. In women aged 35 and older, pregnancy did not increase stroke risk. Women who had pregnancy-related strokes tended to have fewer traditional vascular risk factors like hypertension and diabetes, compared to same-aged women with non-pregnancy related strokes.

Response: Syncope is defined as a sudden loss of consciousness due to transient global cerebral hypoperfusion characterized by rapid onset, short duration, and spontaneous complete recovery. According to the most recent guidelines, syncope can be classified as neurally-mediated, due to orthostatic hypotension and cardiovascular. Syncope is frequent in general population and represents up to 2% of all attendances in Emergency Department in Europe. The initial approach is unable to identify a plausible cause for syncope in 25-30% of cases and approximately 40% of syncope referred to an Emergency Department is then admitted to the hospital. Pulmonary embolism (PE) is an obstruction in the pulmonary arteries interfering with both blood circulation and gas exchange and therefore representing a potentially life-threatening event. Clinical features of PE are extremely variable. Available guidelines on syncope management consider PE as an infrequent cardiovascular cause of syncope. However, the true prevalence of pulmonary embolism in syncope-patients it is actually unknown. Moreover a workup for PE diagnosis in these patients is not suggested in the current guidelines.

Almario, MD, MSHPM Assistant Professor of Medicine Division of Digestive and Liver Diseases, Cedars-Sinai Medical Center Cedars-Sinai Center for Outcomes Research and Education Los Angeles, CA MedicalResearch.com: What is the background for this study? Response: Recent drug approvals have increased the availability of biologic therapies for inflammatory bowel disease (IBD). However, the growing number of biologics has also made it more difficult for both patients and healthcare providers to navigate treatment options and to ultimately choose the most appropriate therapy. In this study, we wanted to examine patient decision-making surrounding IBD biologic therapies using conjoint analysis, which is a form of tradeoff analysis that determines how respondents make complex decisions by presenting them with competing product profiles. Here, we quantified the relative importance of 9 biologic therapy attributes (e.g., how the medicine works, how the medicine is received, long-term effectiveness, side-effect profile, etc.) in the decision-making process.

MedicalResearch.com Interview with: Merete Nordentoft DrMSc Professor, chief Psychiatrist University of Copenhagen Mental Health Centre Copenhagen MedicalResearch.com: What is the background for this study? Response: We knew that children born to parents with mental illness had an increased risk for developing a mental disorder them selves, either the same disorder as their parent or another menal disorder. We also knew that some of these children would have pootrt motor function and other difficulties in functioning. However previous studies were smaller, they were not based on a representative sample, and children were at different age. That is the background for The Danish High Risk and Resilience Study-VIA 7, in which a large group of 522 children and their families were thoroughly assessed.

What are the main findings? Response: PSA testing identifies many men with prostate cancer, but they do not all benefit from treatment. Surgery, radiation therapy and various programs of active monitoring/surveillance can be given as treatments for fit men with clinically localized prostate cancer. Previous studies have not compared the most commonly used treatments in terms of mortality, disease progression and patient-reported outcomes. In the ProtecT study, we used a comprehensive set of validated measures, completed by the men at baseline (before diagnosis), at six and 12 months and then annually for six years. The main finding is that each treatment has a particular pattern of side-effects and recovery which needs to be balanced against the findings from the paper reporting the clinical outcomes (Hamdy et al).

Crandall, MD, MS, FACP Professor of Medicine David Geffen School of Medicine at University of California, Los Angeles UCLA Medicine/GIM Los Angeles, California Dr. Carolyn Crandall[/caption] Carolyn J. Crandall, MD, MS, FACP Professor of Medicine David Geffen School of Medicine at University of California, Los Angeles UCLA Medicine/GIM Los Angeles, California MedicalResearch.com: What is the background for this study? What are the main findings? Response: Scientists have suspected that genes may contribute to the risk of getting hot flashes and night sweats, but studies so far have been few in number and only focused on small parts of the human gene code (for example, the gene coding for estrogen receptors). No study has ever comprehensively sampled gene variations that span the entire human genome to look for associations between genetic variation and risk of hot flashes and night sweats. This was the first study of its kind, performed in more than 17.000 postmenopausal women participating in the Women’s Health Initiative Study. We examined 11,078,977 single-nucleotide polymorphisms, or SNPs, which are gene variants, in a genome-wide association study. Our main results were that 14 gene variants (SNPs) that were significantly associated with increased risk of having hot flashes. All of these variants were located in chromosome 4, in the gene that codes for the tachykinin receptor 3.

What are the main findings? Response: LUX-Lung 7 is the first global, head-to-head trial comparing second- and first-generation EGFR-directed therapies (afatinib and gefitinib respectively) for patients with EGFR mutation-positiveNon-Small Cell Lung Cancer NSCLC who received no prior treatment. The Phase IIb trial included 319 patients with advanced stage NSCLC harboring common EGFR mutations (del19 or L858R). The trial's co-primary endpoints were progression-free survival (PFS) by independent review, time to treatment failure and overall survival (OS); and the secondary endpoints included ORR, disease control rate, tumor shrinkage, patient-reported outcomes and safety.
Author Interviews, JAMA, Surgical Research / 21.10.2016

MedicalResearch.com Interview with: Thue Bisgaard, M.D., D.M.Sc Professor of Surgery, Hvidovre Hospital Hvidovre Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: The complete spectrum for the benefits and risks of mesh used to reinforce hernia repair is not known because there are very few clinical trial data reporting hernia outcomes as they pertain to mesh utilization. Generally, there is evidence that mesh is beneficial in terms of less risk of reoperation for recurrence after incisional hernia repair compared with sutured repair. The present study confirmed this for the first time in nationwide analysis with a long-term follow-up of 5 years up. From earlier studies from our group (Ann Surg 2012) it is known that reoperation rate for recurrence severely underestimates overall (clinical) risk of recurrence making differences between mesh vs. sutured repair even much bigger. Although rare (5%) the incidence of mesh-related complications was progressively increasing throughout the study period suggesting that mesh-related complications rate may continue to accrue with even longer follow-up.

What are the main findings? Response: There has been a longstanding interest in the role of the hormone cortisol in fertility, because of its potential to affect the functioning of the biological systems that influence both conception and pregnancy. This interest has extended to IVF, with researchers exploring the relationship between levels of the hormone and pregnancy since the advent of the treatment in the late 1970s. However, a recent review showed that the relationship between cortisol and pregnancy in IVF was unclear. A number of reasons were highlighted for this, including that all of the studies to date had relied on short-term measures of the hormone measured in blood, saliva, urine and sometimes follicular fluid. Such measures can only capture hormone levels over a matter of minutes and hours. Such ‘snapshots’ are unable to give us an accurate picture of the levels of hormone over longer periods of time. This is important because any clinically relevant effects of cortisol on fertility are only likely to occur in the context of long-term changes in the hormone. In recent years it has become possible to measure long-term levels of cortisol in hair. Cortisol is deposited in the hair shaft and because human hair grows, on average, 1cm per month, a 3cm sample of hair closest to the scalp can tell us about levels of cortisol in the previous 3 months. We used the development of this technique to examine whether long term levels of cortisol (as measured in hair), or short term levels of cortisol (as measured in saliva) could predict whether or not women going through IVF would become pregnant. If you are trying to obtain a perfect cortisol balance, I use this product that helps to do just that.

MedicalResearch.com Interview with: [caption id="attachment_29027" align="alignleft" width="100"]Professor Ivan Martin, PhD Department of Surgery and Department of Biomedicine University Hospital Basel University of Basel, Basel, Switzerland Prof. Ivan Martin[/caption] Professor Ivan Martin, PhD Department of Surgery and Department of Biomedicine University Hospital Basel University of Basel Basel, Switzerland MedicalResearch.com: What is the background for this study and new use of autologous nasal chondrocytes? Response: We previously demonstrated that nasal chondrocytes, harvested from the nasal septum, have a larger and more reproducible capacity to form new cartilage than articular chondrocytes, harvested from the knee joint. We further established that the cartilage tissue generated by nasal chondrocytes can respond to physical forces (mechanical loads) similar to articular cartilage and has the ‘plasticity’ to adapt to a joint environment, since it efficiently integrated with surrounding articular cartilage when implanted in goat joints. This was the rationale for using nasal chondrocytes for articular cartilage repair.
