MedicalResearch.com: What are the main findings of the study?
Dr. Joynt: The main findings of the study were two-fold.
First, high-cost patients in Medicare (the top decile of spenders) are responsible for about 80% of inpatient spending in the Medicare program, so understanding more about these patients' patterns of care is really important.
Second, we found that only about 10% of acute-care spending for these high-cost Medicare patients were for causes that we generally think of as preventable in the short term, like uncontrolled diabetes, COPD, or heart failure.
The rest of the spending was for acute conditions that we generally don't think of as preventable (at least in the short term), such as orthopedic procedures, sepsis, and cancer.

MedicalResearch.com: What are the main findings of the study?
Dr. Redline: Among children with sleep apnea, early adenotonsillectomy resulted in significant improvements in breathing during sleep, daytime behavior, sleep related symptoms, sleepiness and quality of life when we valuated 6 months after surgery.

MedicalResearch.com: What are the main findings of the study?
Dr. Jones: We had previously reported on the cholesterol lowering efficacy of bile salt hydrolase active L. reuteri NCIMB 30242 due to reduced intestinal sterol absorption.
However, the effects of bile salt hydrolase active L. reuteri NCIMB 30242 on fat soluble vitamins was previously unknown and was the focus of the study.

TITLE: Retinal Vessel Caliber and Lifelong Neuropsychological Functioning An international research team from the USA, UK, Singapore and New Zealand reports that the size of the blood vessels in the back of the eye can indicate the health of the brain of people approaching midlife (age 38 years), years before age-related declines in brain functioning.

MedicalResearch.com: What are the main findings of the study?
Dr. Hart: Football players often sustain numerous concussive and subconcussive impacts—head impacts that do not elicit neurologic symptoms that may lead to white matter damage. We evaluated a population of retired NFL players in order to study the relationship between white matter integrity and the manifestation of depressive symptoms. We identified, for the first time, a correlation between depression and white matter abnormalities in former players with a remote history of concussion using diffusion tensor imaging (DTI).
Our data demonstrated a significant association between white matter integrity, as measured by DTI Fractional Anisotropy (FA), and the presence as well as severity of depressive symptoms in retired NFL athletes with a history of concussive or subconcussive impacts. We also found that dysfunction of the anterior aspect of the corpus callosum (forceps minor) and its projections to the frontal lobe can identify those with depression with 100% sensitivity and 95% specificity.

Cancer risk in 680 000 people exposed to computed tomography scans in childhood or adolescence: data linkage study of 11 million Australians
MedicalResearch.com: What are the main findings of the study?
Prof Mathews: We found that for persons having at least one CT scan before the age of 20 years, and followed for an average period of 10 years, the average risk of cancer was increased by 24% compared with unexposed persons matched for age, sex and year of birth. The cancer risk increased by 16% for each CT scan that preceded the cancer by more than one year. The proportional increase in risk was greater for persons exposed at younger ages.

from Channing Division of Network Medicine in Boston, a research division within the Department of Medicine at Brigham and Women’s Hospital, Boston Mass
MedicalResearch.com: What are the main findings of the study?
Dr. McMullan: In this observational study performed in non-diabetic women we found that lower nocturnal melatonin secretion predicted future risk of developing type 2 diabetes. When we categorized the individuals by category of nocturnal melatonin secretion we found that those in the lowest category had twice the risk as those in the highest category of nocturnal melatonin secretion. This association remained even after adjusting for other well established risk factors for development of diabetes including body mass index, physical activity, dietary factors, family history of diabetes, smoking and hypertension. This increased risk translates into the lower melatonin secretion group having an additional 5 cases of incident diabetes per 1000 person years than the high melatonin secretion group.
MedicalResearch.com Interview Dr. Alexander Turchin M.D.,M.S.
Director of Informatics Research
Assistant Professor, Harvard Medical School

MedicalResearch.com: What are the main findings of the study?
Dr. Turchi: A large number of patients – 17% of individuals included in our study – report side effects to statins in routine care settings. Nearly 60% of these patients stopped the statin at least temporarily. However, overwhelming majority of patients who stopped taking a statin after experiencing a possible side effect, could tolerate a statin long-term if they tried taking one again. In other words, it appears that many statin-related events are tolerable, specific to individual statins or have other causes. These findings are consistent with the current guidelines that urge a conservative approach to statin discontinuation. They are particularly important because statins have been convincingly shown to save lives – they decrease all-cause mortality, and also cardiovascular mortality and incidence of cardiovascular events in patients with ischemic heart disease and / or elevated cholesterol levels.

MedicalResearch.com: What are the main findings of the study?
Dr. Branstetter: This study demonstrated that the time to the first cigarette of the day after waking is associated with increased levels of a NNAL, a metabolite of a powerful tobacco-specific carcinogen, NNK -- even after controlling for the total number of cigarettes smoked per day.
For years, the time to the first cigarette of the day after waking was one of several questions assessing nicotine dependence on the Fagerstrom Test for Nicotine Dependence (FTND), the gold standard questionnaire int he field. Over time, it was found that much of the predictive validity of the FTND was due to the time to first cigarette item. Researchers have found that single time to first cigarette item was highly correlated with other measures of nicotine dependence, and was predictive of more difficulty quitting smoking and increased intake of nicotine. Our current study demonstrates that this behavioral measure, is predictive of exposure to the cancer-causing components of cigarettes, regardless of the total number of cigarettes smoked per day. The results suggest that researchers, clinicians and smokers can assess the level of nicotine dependence and potential cancer risk by looking at the time to the first cigarette of the day after waking.
