MedicalResearch.com: What is the background for this study?Dr. van Karnebeek: The goal of the study was to diagnose patients with genetic conditions and discover and describe new diseases with potential for treatment. The study included patients with neurodevelopmental conditions that doctors suspected were genetic or metabolic in origin but had not been diagnosed using conventional methods. Our team tested the children and their parents using a combination of metabolomic (large scale chemical) analysis and a type of genomic sequencing called whole exome sequencing. With this state-of-the-art technique, experts analyze and interpret the portion of DNA called genes that hold the codes for proteins.
Some people’s intellectual disability is due to rare genetic conditions that interfere with the processes the body uses to break down food. Because of these metabolic dysfunctions, there is an energy deficit and build-up of toxic substances in the brain and body leading to symptoms such as developmental and cognitive delays, epilepsy, and organ dysfunction. Some of these rare diseases respond to treatments targeting the metabolic dysfunction at the cellular level and range from simple interventions like dietary modifications, vitamin supplements and medications to more invasive procedures like bone marrow transplants. Because the right treatment can improve cognitive functioning or slow or stop irreversible brain damage, early intervention can improve lifelong outcomes for affected children and their families.

Prof. Jagger: Although we know that life expectancy at older ages is increasing, there is still uncertainty about whether the extra years are healthy ones. Our results are based on data from the Cognitive Function and Ageing Studies (CFASI and II), two cohorts of people aged 65 years and over in three centres in England (Cambridgeshire, Newcastle and Nottingham) who were interviewed in 1991 and 2011. The participants, over 7000 people in each study, were recruited from general practices in the area and included those living in care homes to ensure our results reflect the total older population.
Medical Research: What are the main findings?
Prof. Jagger: We used three health measures to calculate the health expectancies at age 65: cognitive impairment, self-perceived health and disability (mild and moderate/severe). Over the 20 year period women’s life expectancy at age 65 increased by 3.6 years whilst they gained 4.4 years free of cognitive impairment, 3.1 years in good self-perceived health but only 0.5 years free of disability. Men on the other hand lived an extra 4.5 years in total with gains of 4.2 years free of disability, 3.8 years in good self-perceived health and 2.6 years free of disability. So all the extra years of life were free of cognitive impairment for women but most were spent with disability, although the gains were in mild rather than more severe disability.

Response: Understanding the disabling process at the end of life is essential for informed decision-making among older persons, their families, and their physicians.
We know from prior research that the course of disability at the end of life does not follow a predictable pattern for most older persons. This raises the question about what is driving the development and progression of disability at the end of life.
We identified six distinct trajectories of disability in the last year of life, ranging from the least disabled to most disabled. We found that the course of disability in the last year of life closely tracked the monthly prevalence of hospitalization for each of the six trajectories.

Medical Research: What is the background for this study? What are the main findings?
Dr. Wang: The purpose of the study was to examine the survival of children with one or more of 21 major birth defects in the United States. We used data from 12 population-based birth defects surveillance programs that participate in the National Birth Defects Prevention Network. The study included nearly 100,000 infants born with birth defects between 1997 and 2007.
We found that children who were born with hypoplastic left heart syndrome (a severe congenital heart defect) had the lowest chance of survival across multiple ages (up to 28 days of life, 1 year, 2 years, and 8 years of life), compared to children with any other birth defects studied. We also found that the chances of survival up to 1 year of life was greater than 90% for babies born with spina bifida, cleft palate, cleft lip with or without cleft palate, pyloric stenosis, gastroschisis, or Down syndrome. For most birth defects, survival was poorer among non-Hispanic black mothers and Hispanic mothers compared to non-Hispanic white mothers.

Medical Research: What are the main findings of the study?Dr. Margolis: The study compared falls and fractures in patients aged 40-79 with diabetes who were treated for high blood pressure. One group received treatment that aimed at getting systolic blood pressure under 120, while the other group received treatment to achieve systolic blood pressure under 140. The results show that patients who received intensive blood pressure treatment did not fall more than less intensively treated patients, nor did they incur more fractures over an average follow-up of about five years.

MedicalResearch: What are the main findings of this study? Dr. Honeybul: Amongst those patients who had been adjudged severely disabled or in a vegetative state at 18 months, remained as such at the three years follow up.
Most patients who were able to provide a response said that they would have provided consent to the "life saving" intervention even if they had known their final outcome
MedicalResearch.com Interview with:Dr Damian Hoy

School of Population Health
MedicalResearch.com: What are the main findings of the study?Dr. Hoy: The study was part of the Global Burden of Disease 2010 study, which was conducted by the University of Queensland, Harvard University, Johns Hopkins University, University of Washington, and hundreds of disease experts throughout the globe. It is the largest ever public health study. It compared the overall burden (in terms of both death and disability) of the most common 291 diseases/conditions in the world. Low back pain was found to cause more global disability than any other disease/condition. If this is something you are going through, it may be worth knowing that marijuana strains for back pain is one of the most powerful remedies. You've possibly tried everything in the shop and over the counter medicine. So why not give this a go and see how you get on. There's no harm in trying.
Global disability from low back pain is increasing. There is an urgent need for global, regional and national agencies to pay far greater attention to the disability caused by low back pain. In the developed world there are low back pain therapy treatments available whereas, in the developing world things aren't as accessible.

MedicalResearch.com: What are the main findings of the study?Answer: Researchers at Baker IDI Heart and Diabetes Institute reviewed previously published literature on the association between diabetes and the risk of developing physical and functional disability. In this study, disability was defined by a person’s difficulty walking; carrying out daily activities such as using a telephone or transport, managing finances, shopping; or attending to basic self-care needs such as eating, dressing and bathing. Although there have been many previous studies on diabetes and disability, the findings have varied and to date, no one has pooled all studies together for a combined measure of risk. From 26 relevant studies, we measured the pooled effect of the association between diabetes and disability. We found that diabetes increased the risk of disability by 50-80% compared to those without diabetes and this result was consistent across all types of disability. (more…)

MedicalResearch.com: What are the main findings of the study?Answer: The New York State Department of Health (NYSDOH) Overweight and Obesity Brief was derived from information gathered for the NYS Behavioral Risk Factor Surveillance System (BRFSS). The BRFSS is an annual statewide telephone survey of adults administered by the provide information on behaviors, risk factors, and utilization of preventive services. The survey conducted in 2011 found that nearly 25% of adults in NYS are obese and another 36% overweight. It also found that obesity rates are higher among adults who are Black (32.5%), earn an annual household income less than $25,000 (26.8%), have less than a college education (27.1%), or are currently living with a disability (34.9%). These findings bring to light that social and economic factors in our communities can be a major contributor to health disparities, like greater risk of obesity among people of color, low income individuals, and people who are disabled.
