MedicalResearch.com: What are the main findings of the study?
We completed a best evidence topic in interventional cardiac surgery to investigate the significance of elevated markers of cardiac damage following percutaneous coronary intervention (PCI).
We compared the clinical and prognostic relevance of the elevation of creatinine kinase-myocardial band (CK-MB) and cardiac troponin (cTn) levels during peri-procedural period and post-procedural period, respectively, following an emergency or elective PCI.
We found in excess of 390 papers after a systematic literature search, of which 10 represented the best evidence to answer the clinical question. From the best evidence available we showed that the monitoring of cardiac biomarkers following PCI can provide important clinical information about the health of the myocardium, as well as prognostic information on short to mid-term outcomes of mortality up to 3 years.

MedicalResearch.com: What are the Main Findings of this study?
Dr. Rosner: The risk of elevated blood pressure (BP) among children has increased 27% over a 13-year period based on a study among 11,636 children ages 8-17 seen in the NHANES study from 1988-2008. In NHANES III (1988-1994) the risk was 15.8% among boys and 8.2% among girls. In NHANES 1999-2008 (1999-2008) the risk was 19.2% among boys and 12.6% among girls.
Important risk factors for elevated BP were BMI, waist-circumference and sodium intake.
Risk approximately doubled for children in the highest age-sex-specific quartile of BMI vs. children in the lowest quartile
Risk approximately doubled for children in the highest age-sex-specific quartile of waist circumference vs. children in the lowest quartile
Risk increased 36% among children with dietary Na intake > 3450 mg/day vs. children with intake <2300 mg/day. Na intake was normalized per 2000 calories.
There were large increases in both mean BMI and mean waist circumference over the 13-year period, especially for girls.

MedicalResearch.com: What are the main findings of the study?
A: We estimated nearly 9 million people aged 40 years and older are visually impaired using the National Health and Nutrition Examination Survey. Three out of every four people aged 40 years and older with VI have uncorrected refractive error that could be easily corrected with simple glasses or contact lenses. The ocular disease most associated with visual impairment in our study sample was age-related macular degeneration. Finally, increasing age and low educational attainment were significant predictors of visual impairment.

MedicalResearch.com: What are the main findings of the study?
Dr. Swithers: The paper examined the last 5 years of studies that looked at risks associated with consuming artificially sweetened beverages like diet soda. These studies indicated that those who consume diet soda were at significantly greater risk for a variety of negative health outcomes like type 2 diabetes, coronary heart disease, hypertension and stroke, along with being more likely to gain excess weight. These effects might be due to a disruption of basic learned response. The idea is that normally things when things that taste sweet are consumed, the body receives calories and sugar. Our bodies can learn to prepare to deal with these calories and this sugar by starting up our digestive processes as soon as the sweet taste hits our mouth, for example by releasing hormones that not only help us regulate blood sugar, but also can contribute to feelings of fullness. When we consume diet sodas, the mouth gets the sweet taste, but the body doesn't get the calories or the sugar. The body may then learn that a sweet taste in the mouth doesn't always predict sugar and calories, so it makes adjustments in how many hormones it releases. So when we actually consume real sugar, the body doesn't produce the same kinds of physiological responses, which can lead to overeating, higher blood sugar, and over the long term could contribute to diseases like diabetes and stroke.

Royal Centre for Defense Medicine, Birmingham, England
MedicalResearch.com: What are the main findings of the study?
Answer: Our study was a meta-analysis, which combined the findings from 8 randomized controlled trials that included a total of 623 patients. The key finding was that delayed primary skin closure (DPC) for contaminated and dirty abdominal incisions may reduce the rate of surgical site infection. However, due to high risk of bias from the included studies, including flaws in study design, definitive evidence is lacking.
We believe that this meta-analysis represents an exciting development in biomedical publishing; this was a true collaboration between US and UK military surgeons to examine an area of major concern and interest to surgeons everywhere. This work uses experience hard-won on the battlefields of Iraq and Afghanistan, combined with published surgical trials, to inform both future research activity as well as military and civilian surgical practice. This cross-fertilization of ideas is one positive consequence of all the sacrifice and suffering of recent conflicts.

MedicalResearch.com: What are the main findings of the study?
Dr. Belkin: Modern ophthalmic treatment, when freely available is able to reduce the incidence of blindness, and presumably visual impairment considerably. In Israel the rate of new cases of blindness per 100.000 people [age adjusted] was reduced between 1999 and 2010 from 33.8 to 14.8, i.e., by over 56%. The reduction was in all major causes of blindness, Age-related Macular Degeneration (AMD), Glaucoma, Diabetic Retinopathy and Cataract. In the non-treatable retinal dystrophies such as retinitis pigmentosa, there was no significant changes over this period.

MedicalResearch.com What are the main findings of the study?
Dr. Beyerlein: We identified respiratory infections in early childhood, especially in the first year of life, as a risk factor for islet autoimmunity, which is known as a precursor of type 1 diabetes (T1D). We also found some evidence for short term effects of infectious events on development of autoimmunity.

MedicalResearch.com: What are the main findings of the study?
Dr. Paterno: Our study suggests that young patients (average age 16 y/o) who return to pivoting and cutting sports after Anterior cruciate ligament (ACL) reconstruction are 6 times more likely to suffer a second ACL injury than an individual with no prior history of ACL injury. In addition, females after ACL reconstruction may be more likely to injury their opposite limb than actually re-injure the same limb they initially hurt. Finally, when you look at the results of this 2 year outcome study in conjunction with the 1 year outcomes we published last year, it would appear that the greatest risk of suffering a second ACL injury is within the first several months after returning to sports.

Polygenic risk and the development and course of asthma: an analysis of data from a four-decade longitudinal study
MedicalResearch.com: What are the main findings of the study?
Dr. Belsky : We looked to the largest-ever genome-wide association study of asthma (that study by the GABRIEL Consortium included more than 26,000 individuals) to identify genetic variants that could be used to construct a genetic profile of asthma risk. We then turned to The Dunedin Multidisciplinary Health and Development Study, a unique cohort of 1,000 individuals who have been followed from birth through their fourth decade of life with extensive measurements of asthma and related traits. We computed a “genetic risk score” for each person based on the variants identified in GWAS. Then, we looked at who developed asthma, when they developed asthma, and what that asthma looked like in terms of allergic response and impaired lung function.
What we found:
(1) People with higher genetic risk scores were more likely to develop asthma and they developed asthma earlier in life.
(2) Among children who developed asthma, the ones at higher genetic risk were more likely to have persistent asthma through midlife.
(3) Genetic risk was specifically associated with allergic asthma that resulted in chronic symptoms of impaired lung function.
(4) People with higher genetic risk score developed more severe cases of asthma. As compared to people with a lower genetic risk, they were more often absent from school and work because of asthma and they were more likely to be hospitalized for asthma.
(5) The genetic risk score provided new information about asthma risk that could not be obtained from a family history.

MedicalResearch.com: What are the main findings of the study?
Dr. Bosland: Daily consumption of a supplement containing soy protein isolate for two years following radical prostatectomy did not reduce recurrence of prostate cancer in men at high risk for this (radical prostatectomy is surgical removal of the prostate to treat prostate cancer). The study showed that this soy supplementation was safe. It is not clear whether this result indicates that soy does not prevent the development of prostate cancer, but men that have the disease probably do not benefit from soy supplementation.

MedicalResearch.com: What are the main findings of the study?
Answer: Type 2 Diabetes is the leading cause of end-stage renal failure and dialysis in many countries. Early identification of those who are at risk within primary care could prompt more intensive intervention to control glycaemia and blood pressure and use of ACE inhibitors or angiotensin receptor blockers to slow progression. Traditionally estimated glomerular filtration rate and/or urine albumin creatinine ratio have been used to alert clinicians of deteriorating renal function in people with diabetes. However, a far more accurate renal risk score has been developed that combines serum creatinine, demographic characteristics, albuminuria, glycaemia, blood pressure, cardiovascular co-morbidity and duration of diabetes.
The 5-year renal risk score was developed by following more than 25,000 people with type 2 diabetes in New Zealand for a median of 7.3 years (equivalent to 180,497 person-years). The study identified those who commenced dialysis for end-stage renal disease, received a renal transplant or died from renal failure to derive the risk score.

Disruption of the Circadian Clock in Mice Increases Intestinal Permeability and Promotes Alcohol-Induced Pathology and Inflammation
MedicalResearch.com: What are the main findings of the study?
Answer: The main findings of the study were that disruption of circadian rhythms, which we achieved using independent genetic and environmental strategies in mice, leads to impaired function of the intestinal epithelial barrier. This loss of epithelial barrier integrity, which has been associated with numerous diseases, results in "gut leakiness," a phenomenon in which endotoxin from gut bacteria can cross the intestinal wall and enter circulation, promoting inflammation. In particular, using in a disease model of gut-derived endotoxemia and inflammation, alcoholic liver disease, we found the circadian disruption interacted with alcohol, leading to increased gut leakiness, inflammation and liver damage.
