MedicalResearch.com: What are the main findings of the study?
Dr. Rochon: Our main findings are that there are now more than 1800 centenarians in Ontario. Among those over 100 years of age, 60 per cent are 101 years of age or older. In addition, most centenarians are women (85 per cent), and this percentage increases to 90 per cent among those who are 105 years of age and older.

Now with the School of Psychology, University of Sydney, Sydney, Australia
MedicalResearch.com: What are the main findings of the study?
Dr. Allsop: We found that administering a botanical preparation of the cannabinoids Tetrahydrocannabidiol (THC - the main psychoactive ingredient in cannabis) and Cannabidiol (a lesser known component of the cannabis plant that
counteracts the psychotogenic effects of THC with anxiolytic properties) to
dependent cannabis smokers during initial abstinence from cannabis
substantially dampened their withdrawal experience. In essence this is akin
to Nicotine Replacement Therapy (NRT) but for cannabis users. It might seem
obvious - sure you give cannabis users a cannabis preparation and they find
it easier to quit - but this is important because it has never been done
before - and we currently have no consensus evidence based medicines to
offer cannabis users who ask for help.

MedicalResearch.com: What are the main findings of the study?
Dr. Walkey: Thank you for the interest in our study. Current evidence-based treatments for severe sepsis (ie, infection+systemic inflammatory response+ end organ dysfunction) include specific processes of care rather specific therapeutics. These processes include early administration of antibiotics, early fluid resuscitation, and lung protective ventilation strategies. We hypothesized that hospitals with more ‘practice’ at treating patients with severe sepsis may have more effective care processes leading to improved patient outcomes. We examined more than 15,000 severe sepsis admissions from 124 US academic medical centers. Our findings supported our hypothesis. After adjustment for patient severity of illness and hospital characteristics, mortality in the highest quartile severe sepsis case volume hospitals was 22% and mortality in lowest severe sepsis case volume hospitals was 29%. The 7% absolute mortality difference would result in an estimated number needed to treat in high severe sepsis volume hospitals to prevent one death in low case volume hospitals of 14 (though we advise caution in interpretation of a number needed to treat in an observational study). Costs and length of stay were not different across levels of severe sepsis case volume. Results were robust to multiple subgroup and sensitivity analyses.

MedicalResearch.com: What are the main findings of the study?
Answer: In total 12% of the adult general public was found to experience harm from medicines, i.e. adverse drug events (ADEs), when we scrutinised the medical and dispensing records of 4970 adults in Sweden during three months, including 29 inpatient care departments in three hospitals, 110 specialised outpatient clinics, and 51 primary care units. Most ADEs were adverse drug reactions (also called side effects) and sub-therapeutic effects. Commonly used drugs caused most ADEs, with a high frequency of adverse drug reactions from antidepressants and cardiovascular drugs as well as sub-therapeutic effects of analgesics and cardiovascular drugs. Of all ADEs, 39% were potentially preventable, because the drug therapy or use was judged suboptimal.

MedicalResearch.com: What are the main findings of the study?
Dr. Wakeam: Our study examined failure to rescue (FTR), or death after postoperative complications, in safety net hospitals. Prior work has shown that hospital clinical resources can improve rescue rates, however, despite having higher levels of technology and other clinical resources that should lead to better rates of patient rescue, safety net hospitals still had greater rates of death after major complications.
MedicalResearch.com Interview with:
Dr. Daniel S. Budnitz MD MPH CAPT, USPHS
Division of Healthcare Quality Promotion

Atlanta, Georgia
MedicalResearch.com: What are the main findings of the study?
Dr. Budnitz: To reduce dosing errors when administering orally ingested over-the-counter (OTC) liquid medications, especially among children, the US Food and Drug Administration (FDA) released and the Consumer Healthcare Products Association (CHPA) released recommendations for how to display dosing directions and markings on dosing devices.
This study assessed recommendation adherence for national brand name orally ingested OTC liquid pediatric analgesics/antipyretics and cough, cold, and allergy products available after the FDA guidance was finalized in 2011. To identify and prioritize specific areas for improvement, recommendations were categorized as ‘top tier’ (potential to address ≥3-fold errors) or ‘low tier’ (intended to improve clarity and consistency).
Of 68 products, 91% of dosing directions and 62% of dosing devices adhered to all top tier recommendations; 57% of products adhered to every top tier recommendation, and 93% adhered to all or all but one. A dosing device was included with all products (e.g., oral syringe, dosing cup). No dosing directions used atypical volumetric units (e.g., drams), and no devices used volumetric units that did not appear in dosing directions. Six products used trailing zeros or failed to use leading zeros with decimal doses; eight did not use small font for fractions. Appropriate use of zeros and decimals is important to avoid 10-fold overdoses; using small font for fractions (½ vs. 1/2) helps avoid potential 4-fold errors if 1/2 interpreted as 1 or 2. Product adherence to low tier recommendations ranged from 26% to 91%.

Associate Professor, Faculty of Medicine, University of Toronto
MedicalResearch.com: What are the main findings of the study?
Dr. Grigoriadis: Infants of women exposed to selective serotonin reuptake inhibitors (SSRIs) during late pregnancy (but not early) are at risk for developing persistent pulmonary hypertension of the newborn (PPHN). PPHN is a condition in which blood pressure remains high in the lungs following birth and which results in breathing difficulties. The symptoms can range from mild to severe, but the condition can be managed successfully typically after SSRI exposure. It is important to note that the baseline risk for PPHN in the general population is low (about 2 per 1,000 live births), and so the increase in risk with SSRIs still represents a low overall risk for developing PPHN following SSRI exposure in late pregnancy (increasing to approximately 5 per 1,000 live births). This increased risk means that 286 to 351 women would have to be treated with an SSRI during late pregnancy in order to result in 1 additional case of PPHN.

MedicalResearch.com: What are the main findings of the study?
Answer: We used trained actors to test whether servers in pubs, bars and nightclubs would sell alcohol to people showing signs of extreme intoxication, despite this being illegal in the UK. In over four fifths (83.6%) of purchase attempts, bar servers sold alcohol to the pseudo-drunk actors – even though many clearly identified the actors as being drunk. We also collected data on bar environments, looking specifically at ten factors that have been associated with alcohol-related harm in previous studies: low levels of seating, loud noise, crowding, poor lighting, dirtiness, cheap drink promotions, young bar staff, young customers, rowdiness, and customer drunkenness. We found that the more of these characteristics bars had, the more likely they were to sell alcohol to drunks, with 100% of bars with 8 or more of these characteristics serving the pseudo-drunk actors. However, even in bars with none of these characteristics, two thirds of purchase attempts resulted in an alcohol sale. Having security staff managing entrance to the premises was also associated with alcohol service; possibly suggesting that bar servers in premises with door staff believe responsibility for vetting customers lies with such staff.

MedicalResearch.com: What are the main findings of the study?
Answer: The study examined 23.434 children at 4 and 8 years from 12 ongoing European population-based birth cohort studies that recorded information on current eczema, rhinitis, and asthma from questionnaires and serum-specific IgE to six allergens. We wanted to assess how often eczema, rhinitis and asthma coexist in the same children (comorbidity) and whether the occurrence of comorbidities was due to causality or casualty and finally we wanted to examine whether the occurrence of comorbidity was modified by IgE sensitization.
We found that comorbidity affects about 4% of children aged 4–8 years and that about 50% of this comorbidity is due to causality, suggesting that these diseases share common pathophysiological mechanisms. In addition, we found that children comorbidity at age 4 are 30 to 60 times more likely to have comorbidity at age 8 years, suggesting that the presence of comorbidity at age 4 years is a strong determinant of comorbidity at age 8 years. Even children with one single disease are also at high risk of developing comorbidity by age 8 years. Interestingly, we found that not only comorbidity is present in children both sensitized and not sensitized to IgE but also that only 38% of incident comorbidity at age 8 years is explained by the presence of IgE sensitization at age 4 years.

MedicalResearch.com: What are the main findings of the study?
Prof. Burley: Although it’s been suggested for a long time that foods rich in dietary fiber may protect individuals from having a heart attack or stroke because they lower some of the risk factors for these diseases, trying to determine how much dietary fibre might be beneficial and whether these benefits are apparent in all populations around the world has been less easy to research. Our research at the University of Leeds has pooled the results of published large-scale follow-up studies and has demonstrated a consistent lowering of risk of cardiovascular and coronary heart disease with increasing dietary fiber intake. This dose-response trend suggests that even small additional increments in intake may be beneficial in the long term.
MedicalResearch.com Interview with:
W. Katherine Yih Ph.D., M.P.H
Department of Population Medicine

MedicalResearch.com: What are the main findings of the study?
Dr. Yih: The main findings are that vaccination with the first dose of RotaTeq is associated with a small increase in the risk of intussusception, which is concentrated in the first week after vaccination. The estimated risk is about 1.5 excess cases per 100,000 first doses administered. This risk is fairly small, amounting to roughly 1/10 of the risk seen after the original rotavirus vaccine (called Rotashield) that was used in 1998-1999, before it was withdrawn from the market.
We also found evidence that Rotarix increases the risk of intussusception. However, the number of infants receiving Rotarix and the number getting intussusception after Rotarix were too small to allow us to estimate the risk after Rotarix with any precision.
MedicalResearch.com Interview with:
Jyrki Virtanen, PhD
Adjunct Professor of Nutritional Epidemiology
University of Eastern Finland
Institute of Public Health and Clinical Nutrition
Kuopio, Finland
MedicalResearch.com: What are the main findings of the study?
Dr. Virtanen: The main finding was that serum long-chain omega-3 polyunsaturated fatty acid (PUFA) concentration, an objective biomarker of fish and long-chain omega-3 PUFA intake, was associated with a lower risk of incident type 2 diabetes during the average follow-up of 19.3 years in middle-aged and older men from Eastern Finland. The risk was 33% lower in the highest vs. the lowest quartile after adjustment for potential confounders. In contrast, hair mercury, a marker for long-term exposure to mercury, was not associated with the risk. Previously in this study population, high hair mercury content has been associated with higher risk of cardiovascular diseases and attenuation of the beneficial impact of long-chain omega-3 PUFA on the risk. Also, we did not find associations with the intermediate-chain length omega-3 PUFA alpha-linolenic acid, either, which is a plant-based omega-3 PUFA. This suggests that the findings were specific to the long-chain omega-3 PUFAs from fish.

Yvonne M. Terry-McElrath, MSA
Institute for Social Research, University of Michigan, Ann Arbor
MedicalResearch.com: What are the main findings of the study?
Answer: This study examined 2007-2012 commercialism trends in schools attended by nationally representative samples of US elementary and secondary students.
While some measures showed significant decreases over time (especially
beverage vending measures), most students at both elementary and secondary
school levels continued to be exposed to school-based commercialism.
Commercialism increased significantly with grade level. The most frequent
type of commercialism varied by school level: food coupons used as
incentives was most common at the elementary school level, while exclusive
beverage contracts were the most prevalent type of commercialism for middle
and high school students.
MedicalResearch.com Interview with:
David M. Albala, MD
Associated Medical Professionals of NY, PLLC
Syracuse, NY 13210
MedicalResearch.com: What are the main findings of the study?
Dr. Albala: Prostate cancer is the second leading cause of cancer death and American man. Prostate cancer diagnosis and mortality differences between African American and Caucasian populations have been highlighted in the literature. Research has shown that African American males are at a biological predisposition for prostate cancer and that additional socioeconomic and physician-patient educational factors may contribute to a higher mortality rate among this group - over two times greater than that of Caucasian American males.
At present the most commonly used to detection tools for prostate cancer are the serum prostatic specific antigen test (PSA) and a digital rectal examination (DRE). These complementary tests provide physicians with an indication of whether to proceed with biopsy for a definitive pathological diagnosis. Despite ongoing disputes regarding the effectiveness of PSA screening as an indicator for prostate cancer, a superior alternative test as yet to become available for men at risk.
The American Urological Association (AUA) emphasizes the value of early detection and that sheared decision-making should not be overlooked and that shared decision making should be integral to screening decisions. The AUA urges individuals to personally assess, with their physicians, whether a PSA screen is necessary. Emphasis should be placed on the proper education of African American men who are at increased risk for the disease, as well as on their participation in repeated screening practices for the earliest possible detection of prostate cancer.

MedicalResearch.com: What are the main findings of the study?
Dr. Banks: We asked members of the public attending their local general practice or
primary care centre to consider a series of hypothetical scenarios or
vignettes which depicted cancer symptoms, their risk of cancer and the
investigative processes involved in testing for cancer. We wanted to
measure the point at which the risk of cancer outweighed the burden and
inconvenience of testing in relation to lung, colorectal and pancreas
cancers. Most people, around 88%, opted for testing even at the lowest risk
of cancer which in our vignettes was 1%. Further analyses showed variation
between cancers with fewer people opting for testing for colorectal cancer
at a low (1%) risk and more people choosing to be tested for all cancers in
the 60-69 age group.

MedicalResearch.com: What are the main findings of the study?
Dr. Reynolds: Our survey of factors influencing admission to 13 nursing homes in Orange County, California showed that MRSA carriers are denied admission more often than non-carriers, even after accounting for other important factors such as insurance status, required level of care and previous experience at the facility. In 80% of cases where MRSA carriage was responsible for denial of admission, nursing home administrators cited a lack of available single or cohort (MRSA only) rooms to accommodate these potential residents.
