MedicalResearch.com: What are the main findings of the study?
Answer: The CRISTAL trial was designed in 2002 to clarify whether correction of acute hypovolemia in critically ill patients with colloids may increase the risk of death as compared to resuscitation with crystalloids. The trial has enrolled 2857 patients in 57 ICUs in France, Belgium, Canada and North Africa. The relative risk of death was at 28 day of 0.96 (95% CI: 0.88 to 1.04; P=0.26), and at 90 day of 0.92 (95%CI: 0.86 to 0.99; P=0.03) in favor of colloids. Colloids-treated patients had more days alive and off mechanical ventilation and off vasopressor both within 7 days and 28 days of randomization. There was no evidence for increased risk of kidney injury with colloids.
14 Oct Bisphosphonates: Risks of AFib and Stroke
MedicalResearch.com Interview with:
Abhishek Sharma, M.B.B.S.
Maimonides Medical Center in Brooklyn, N.Y.
MedicalResearch.com: What are the main findings of the study?
Answer: Evidence from RCT's and observational studies suggests a significantly increased risk of atrial fibrillation (AF) requiring hospitalization, but no increase in risk of stroke or cardiovascular mortality with the use of bisphosphonate.
14 Oct Precocious Puberty in Girls: What are Long-Term Outcomes?
MedicalResearch.com Interview with: Dr. Liora Lazar The Jesse Z and Sara Lea Shafer Institute for Endocrinology and Diabetes National Center for Childhood Diabetes Schneider Children's Medical Center of Israel 14 Kaplan St., Petah Tikva 49202, Israel MedicalResearch.com: What are the main findings of the study? Dr. Lazar: The study aims to assess the reproductive outcome and social adjustment of former Central precocious puberty (CPP) women between the 3rd and 5th decades of life. The main findings of this study are: 1. Clinical hyperandrogenism was more prevalent among former CPP women, both treated and untreated, as compared to controls. 2. Fertility problems were more prevalent only among untreated–CPP women. 3. Educational achievements and marital status were similar in former CPP women and their controls.13 Oct Suicide: Bereavement Course in Close Relatives and Spouses
MedicalResearch.com Interview with:
Marieke de Groot, PhD
Senior Researcher
University of Groningen/University Medical Center Groningen
VU University Amsterdam, department of Clinical Psychology
The EMGO Institute for Health and Care Research (EMGO+)
MedicalResearch.com: What are the main findings of the study?
Answer: We investigated the long term course of bereavement through suicide in a community-based sample of 153 first-degree relatives and spouses of 74 suicide cases. Outcome measures were complicated grief, depression and suicide ideation. We found that outcomes are mutually strongly associated over the 8-10 years course. A history of attempted suicide predicts a increased risk of suicide ideation during the bereavement course. Depression is more likely predicted by factors generally associated with a increased risk of depression such as female gender and low mastery, whereas complicated grief is more likely predicted by the trauma of losing a child due to suicide. No significant associations were found between outcomes and the use of help resources except for mutual (or peer) support, which is associated with a increased risk of complicated grief. Time is the only factor (included in this study) predicting decrease of the risk of depression and complicated grief.
13 Oct Venous Thromboembolism: Detection and Surveillance Bias
MedicalResearch.com Interview with:
Mila Ju, MD
Resident, Division of Vascular Surgery
Northwestern University
676 N. Saint Clair St., Ste 650
Chicago, IL 60611
MedicalResearch.com: What are the main findings of the study?
Dr. Ju: By using combined data from Hospital Compare, American Hospital Association, and Medicare claims databases, we found that better hospital venous thromboembolism (VTE) prophylaxis adherence rates were weakly associated with worse risk-adjusted VTE event rates. Moreover, hospitals with higher intensity of detecting VTE with imaging studies (such as venous duplex, chest computer tomography, etc.) had more VTE events (13.5 in highest VTE imaging quartile vs 5.0 in lowest VTE imaging quartile) per 1000 discharges. Our study suggests that VTE rates might be influenced by surveillance bias and not reflecting the true quality of care provided by the hospitals.

171 77 Stockholm, Sweden
MedicalResearch.com: What are the main findings of the study?
Answer: This is a Swedish/Danish population-based study comparing serious disease outcomes in girls immunized with the quadrivalent HPV vaccine against the unvaccinated population.
The main finding of this study was that none of the 53 outcomes included in the study were more common in the vaccinated population compared to the non-vaccinated population.
11 Oct Cardiovascular Disease: Declining Mortality, Increasing Costs and Disability
MedicalResearch.com Interview with:
Ankur Pandya PhD
Assistant Professor of Public Health in the Division of Health Policy
Department of Public Health at Weill Cornell Medical College
MedicalResearch.com: What are the main findings of the study?
Dr. Pandya: Our study looked at the impact of some of the future risk factors for cardiovascular disease in the United States. Using nine National Health and Nutrition Examination Survey waves from 1973 to 2010 we forecasted disease risk and prevalence from 2015 to 2030. We found that despite continued improvements in the disease’s treatment and declining smoking rates, increasing obesity rates, the aging population, and declining mortality from the disease should cause a rise in health care costs, disability, and reductions in the quality of life associated with increased disease prevalence.
11 Oct Thyroid Cancer: Incidence on the Rise, Cause Unknown
MedicalResearch.com Interview with:
David Goldenberg MD, FACS
Professor of Surgery and Oncology
Director of Head and Neck Surgery
Associate Director of Surgical Services- Penn State Hershey Cancer Institute
Division of Otolaryngology-Head and Neck Surgery
The Pennsylvania State UniversityThe Milton S. Hershey Medical Center, Hershey, PA 17033
MedicalResearch.com: What are the main findings of this study?
Dr. Goldenberg: The incidence of thyroid cancer is on the rise and has nearly tripled in the last thirty years.
Some authors have attributed this increase in incidence to improved sensitivity of diagnostic techniques and imaging allowing for diagnosis of small insignificant thyroid cancers. Others do not agree and state that is a real rise in this disease.
Many patients have their cancer discovered by accident when they undergo a diagnostic study for some other reason- such as trauma, neck pain, or carotid artery studies (for clogged arteries).
We aimed to compare incidentally discovered versus non incidentally discovered thyroid cancers to determine whether the thyroid cancers in both groups harbor different characteristics.
11 Oct Episodic Memory Impairments and Tip-of-Tongue Experiences
MedicalResearch.com Interview with:
Prof. Timothy Salthouse
Brown-Forman Professor of Psychology
Department of Psychology
University of Virginia
Charlottesville, VA 22904-4400
MedicalResearch.com: What prompted this work?
Prof. Salthouse: I think it is noteworthy that the research originated as an undergraduate project by Arielle Mandell. Ms. Mandell was supported by a University of Virginia Harrison Undergraduate Research Award while she was doing the research, and a report of the research served as her Distinguished Major Thesis.
The research was prompted by the observation that according to self-reports, tip-of-the-tongue experiences occur more and more frequently with increased age, and often seem to be associated with concerns about memory decline and possibly impending dementia. We wondered
- 1) whether these self-reports are valid, and
- 2) if they are valid, do they truly indicate age-related failures of the type of memory used in the diagnosis of dementia.
11 Oct Gene Predisposes Some to Focus on the Negative
MedicalResearch.com Interview with:
Dr. Rebecca Todd
Assistant Professor
University of British Columbia
Department of Psychology
Centre for Interactive Research on Sustainability
4342A-2260 West Mall
Vancouver, BC V6T 1Z4
MedicalResearch.com: What are the main findings of the study?
Answer: What we found, in essence, is that some individuals are genetically predisposed to see the world more darkly than others. We find that a common gene variant is linked to perceiving emotional events --especially negative ones --¬ more vividly than others. This gene variant has been previously linked (by other researchers) to emotional memory and the likelihood of experiencing intrusive, or “flashback” memories following traumatic experience. Our findings suggest that in healthy young adults this enhanced emotional memory may be because individuals are more likely to perceive what’s emotionally relevant in the first place. We've all heard of rose colored glasses, but this is more like gene-colored glasses, tinted a bit darkly.
11 Oct Breast Cancer Mortality: Multivitamin and Mineral Use

1300 Morris Park Avenue Bronx, NY 10461
MedicalResearch.com: What are the main findings of the study?
Answer: We studied 7728 older women who developed invasive breast cancer during their participation in the Women’s Health Initiative, known as WHI. This study found that women with invasive breast cancer who are users of multivitamin and mineral supplements had a 30% lower risk of dying from their breast cancer compared to non-users. This protective effect was observed to be independent of a large number of factors which affect breast cancer outcomes and which account for differences between users and non-users. The women we studied were ages 50-79 when they started the WHI.
10 Oct It’s Not Just Politics: People with Extreme Attitudes are Inordinately Convinced They Are Right
MedicalResearch.com Interview with:
Kaitlin Toner, Ph.D.
Vanderbilt Institute for Energy and Environment
Vanderbilt Climate Change Research Network
Nashville, TN 37240
Dr. Kaitlin Toner, is a postdoctoral researcher at Vanderbilt University.
The study was conducted colleagues Mark Leary, Michael Asher, and Katrina Jongman-Sereno while Dr. Toner was a graduate student at Duke University.
MedicalResearch.com: What are the main findings of the study?
Dr. Toner: The take home message is that people who hold more extreme attitudes also tend to feel superior about those attitudes, whereas people with moderate attitudes aren't as convinced of the superiority of their own beliefs. Although it might seem that this connection between attitude extremity and superiority seems reasonable, there’s no logical reason why people who hold moderate, middle-of-the-road attitudes should not think that their moderate attitudes are superior to other people’s. But they don’t tend to do that; it’s the people with extreme attitudes who are inordinately convinced that they are right.
These findings are important because it sheds some light on how people become so polarized in their opinions: they don't just take a side, but they believe everyone who disagrees with that view must be wrong. Importantly, it's not just one political party who thinks this way, as previous research had suggested, but rather that it happens for both liberal and conservative attitudes. And, given the stalemate in Washington, understanding why people become so entrenched in their views – even when there is often not an objectively correct answer – is more important than ever.
10 Oct More Fatalities Mean More Donors and Bigger Donations
MedicalResearch.com Interview with:
Ioannis Evangelidis, Ph.D. candidate
Department of Marketing Management,
Rotterdam School of Management
Erasmus University, Rotterdam
MedicalResearch.com: What are the main findings of the study?
Answer: We find that donors pay more attention to the number of people killed when donating to a disaster, than to the number of people who are affected (survive but need money). In other words, people are more likely to donate, and donate more money, the more people die in a disaster, but not when more people survive and need assistance.
10 Oct Breast Cancer: 7 Triple-Negative Subtypes and Chemotherapy Response

Naoto T. Ueno, MD Anderson Cancer Center, 1515 Holcombe Blvd., Unit 1354, Houston, TX 77030.
MedicalResearch.com: What are the main findings of the study?
Answer: Triple-negative breast cancer (TNBC) could be classified into 7 subtypes: basal-like 1 (BL1), basal-like 2 (BL2), immunomodulatory (IM), mesenchymal (M),mesenchymal stem-like (MSL), luminal androgen receptor (LAR), and unstable (UNS). Using cluster analysis, Lehmann and Bauer et al. identified these TNBC subtypes in 21 public mRNA gene expression profiles of breast cancer. However, the clinical relevancy of these novel molecular subtypes has not been established. To establish the clinical relevancy, we determined if the subtypes of TNBC have different rates of pathological complete response (pCR) to standard neoadjuvant chemotherapy regimens. In this study, we confirmed that TNBC is heterogeneous and that pCR differs by TNBC subtype using the algorithm proposed by Lehmann and Bauer et al. The BL1 subtype had the highest pCR rate (52%), and BL2 and LAR had the lowest pCR rates (0% and 10%, respectively). TNBC subtype was an independent predictor of pCR status (P=0.022) via a likelihood ratio test. To our knowledge, this was the first study to show that the TNBC subtype can serve as an independent predictor of pCR status in patients who received standard chemotherapy regimens. This confirms the possible clinical relevance of the 7 molecular subtypes, and these subtypes may lead to innovative clinical trials of personalized medicine for patients with TNBC.
10 Oct Prostate Cancer: PSA Changes in Patients Treated with Treated With Second-Line Chemotherapy
MedicalResearch.com Interview with
Susan Halabi, PhD
Duke University Medical Center
Durham, NC 27710
MedicalResearch.com: What are the main findings of the study?
Dr. Halabi: The purpose of assessing surrogate endpoints is to allow for a more rapid and efficient determination of whether a given therapy provides clinical benefit to patients by prolonging their life.
We sought to evaluate PSA kinetics as surrogate endpoints for overall survival (OS) in mCRPC patients who were receiving second line chemotherapy (cabazitaxel or mitoxantrone) following progression after docetaxel. Using different analytical approaches, we found that PSA declines within the first three months of treatment are not appropriate as surrogate markers of clinical benefit in men who were receiving second line chemotherapy.
This analysis has important clinical care and study design implications: it has become common to use ≥30% decline in PSA as a clinical trial endpoint for all patients with metastatic CRPC, based on the original front-line docetaxel data. The data presented in this study suggest that this is erroneous. Further we believe these data are important because they demonstrate that there are different disease states within the group of patients with “metastatic CRPC". To make the assumption that the same surrogate endpoint can be used across the board may seem like an obvious mistake, but permeates the literature.
10 Oct Probiotics and Infant Colic
MedicalResearch.com Interview with: Dr Valerie Sung MBBS(Hons) FRACP MPH NHMRC PhD Candidate Department of Paediatrics, University of Melbourne, and Community Health Services Research, Murdoch Childrens Research Institute Paediatrician, Centre for Community Child Health The Royal Children’s Hospital Parkville | 3052 | Victoria Australia MedicalResearch.com: What are the main findings of the study? Dr. Sung: The systematic review identified 12 studies (1825 infants) that investigated the use of probiotics to treat or prevent infant colic (excessive crying of unknown cause in babies less than 3 months old). Three of the 5 treatment trials concluded probiotics effectively treat colic in breastfed babies; one suggested possible effectiveness in formula-fed babies with colic, and one suggested ineffectiveness in breastfed babies with colic. The three effective trials used the probiotic Lactobacillus reuteri in breastfed babies only; in two of these trials, the mothers were on a dairy-free diet. Five of the 7 prevention trials suggested probiotics to be ineffective in preventing colic.10 Oct Muscle Wasting in Critical Illness

Kings College Hospital
MedicalResearch.com: What are the main findings of the study?
Answer: That muscle wasting occurs rapidly and early in critical illness, with up to 2-3% loss of muscle mass per day. This is related to the numbers of organs failed, and is made worse by the degree of acute lung injury, and increased protein delivery. Muscle wasting is the result of both decreased muscle protein synthesis and increased muscle protein breakdown. In addition 40% of these patients developed muscle necrosis over the study period.
10 Oct Folate Deficiency May Affect Subsequent Generations Through Epigenetics
MedicalResearch.com Interview with:
Erica D. Watson, PhD
Lecturer in Reproductive Biology Centre for Trophoblast Research Dept Physiology, Development and Neuroscience University of Cambridge, United Kingdom
MedicalResearch.com: What are the main findings of the study?
Dr. Watson: It has been known for decades that maternal folate deficiency increases the risk for a diverse range of health problems in her children, such as spina bifida, heart defects and growth restriction. Despite this, the molecular mechanism of folate during development was not well understood. Our study is important because it shows that the inability to break down folate due to a mutation in the gene Mtrr can affect the health not only in the immediate offspring but also of the next generation.
We used mice for the study as they metabolize folate similarly to humans and because folic acid deficiency or mutations in the genes required to break down folate in humans result in similar developmental abnormalities and diseases in mice. This enabled us to explore how the molecular mechanism of folate deficiency impacted development, thereby causing health problems.

www.oslo-universitetssykehus.no
MedicalResearch.com: What is the background of this study?
Answer: Each year a considerable number of parents with children younger than 18 years of age are affected by cancer in a parent. Cancer in one of the parents might represent a potentially traumatic event and thereby may be a risk factor for psychosocial problems in the offspring. So far, teenagers’ psychosocial responses to parental cancer have only been studied to a limited extent in controlled trials. Using a trauma theory perspective many studies have shown significant direct associations between parental cancer and psychosocial problems in teenagers. However, the literature also indicates that most children and teenagers have normal stress reactions to such events. In order to identify the need for eventual prevention and intervention among teenagers exposed to such a stressor, we need more empirical knowledge of their psychosocial situation.
08 Oct Celiac Disease: When Should Gluten Be Introduced to Infants?
MedicalResearch.com Interview with:
Ketil Stordal
Researcher/consultant paediatrician
National Institute of Public Health
Norway
MedicalResearch.com: What are the main findings of the study?
Answer: The study identified 324 children with celiac disease from a cohort of 82 000. Start of gluten in the diet later than 6 months was associated with a 27% increased risk of celiac disease compared to those starting during the 5th or 6th month of life. Breastfeeding was not protective; the duration of breastfeeding was slightly longer among children with celiac disease (10.4 vs 9.9 months) and breastfeeding at the time of gluten introduction was not associated with the later risk of celiac disease. The participating mothers had submitted detailed data since pregnancy including infant feeding practices, and these were collected before onset of the disease.
08 Oct Breast Cancer: Axillary Node Interventions
MedicalResearch.com Interview with:
Roshni Rao, MD
Division of Surgical Oncology, Department of Surgery
University of Texas Southwestern Medical Center, Dallas
MedicalResearch.com: What are the main findings of the study?
Dr. Rao: That in most women with small breast cancer (<3.0cm in size), it is not necessary to removal all the lymph nodes underneath the arm, even if those nodes do have cancer. Radiation therapy, which is required after a partial mastectomy for breast cancer, can prevent these nodes from growing or becoming clinically significant.

Unit 1362, PO Box 301439, Houston, TX, 77030
MedicalResearch.com: What are the main findings of the study?
Dr. Sood: For women with newly diagnosed ovarian cancer, high heart rate at diagnosis (tachycardia), venous thromboembolism (VTE) occurring after diagnosis and pulmonary hypertension post-diagnosis are independently related to reduced survival after controlling for tumor stage, grade, and extent of cytoreduction. Women with tachycardia lived an average of 4.0 years after diagnosis compared with 5.9 years for women without tachycardia, a 32% reduction in duration of survival. Patients who experienced VTE lived a median 4.1 years after diagnosis, compared with 6.4 yrs for patients who did not experience VTE.
08 Oct Node-Positive Breast Cancer: SLN after Chemotherapy
MedicalResearch.com Interview with:
Kelly K. Hunt, MD F.A.C.S.
Professor, Department of Surgical Oncology, Division of Surgery
Chief, Breast Surgical Oncology Section, Department of Surgical Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX
MedicalResearch.com: What are the main findings of the study?
Dr. Hunt: We found that 40% of women who had node positive disease at initial presentation (confirmed by needle biopsy) had no evidence of residual cancer in the lymph nodes after chemotherapy.
We performed sentinel lymph node (SLN) surgery followed by axillary lymph node dissection in all of the patients and found a false negative rate of 12.6% with the SLN procedure.
The false negative rate was lower when surgeons used two mapping agents (blue dye and radioisotope) to identify the sentinel nodes and when they removed more than 2 sentinel nodes.
07 Oct Aquarium Associated M. marinum infections may be under-recognized

Detroit, MI 48202
MedicalResearch.com: What are the main findings of the study?
Dr. Alangaden:
- Infections caused by Mycobacterium marinum infections are rare. A total of 5 patients were identified in our hospital over a 10 year period.
- In all instances the infection affected the skin and soft tissues of the hand and arm and presented as sores or bumps on the skin that did not improve after usual antibiotic therapy.
- All patients had an history of some trauma to the hand and subsequent exposure to water from home aquariums
- The time to onset of infection after exposure ranged from 11 days to 56 days.
- The median time from infection to diagnosis and appropriate therapy was 161 days (range 33-379 days).
- In all cases the diagnosis was made by doing a skin biopsy.
- All patients were cured after several weeks of treatment with appropriate antibiotics.
07 Oct Antibiotic-Resistant Bacteria and Universal Glove and Gown Use
MedicalResearch.com Interview with:
Anthony Harris, MD, MPH
Department of Epidemiology and Public Health
Professor University of Maryland
School of Medicine
Acting Medical Director of Infection Control
University of Maryland Medical Center
MedicalResearch.com: What are the main findings of the study?
Dr. Harris: The aim of the study was to understand if wearing disposable gowns and gloves for all patient contact in the ICU could help prevent the spread of MRSA and similar antibiotic-resistant bacteria.
Secondarily we wanted to make sure this type of patient isolation did not result in any harm to patients. The results of the study were that gowns and gloves worn by healthcare workers for contact with all patients in the ICU did not decrease the number of patients who acquired VRE but did decrease MRSA about 40 percent. Also, wearing gloves and gowns did not adversely impact patient care. For our goal of studying all types of infection, we did not find a benefit to universal gown and glove use. However, for transmission of MRSA alone, the intervention decreased transmission by about 40 percent. Although previous studies have showed isolation is associated with falls, bed sores and other adverse events, we found gowns and gloves did not produce more of these negative events.
