The World Is Getting Fatter

Posted on December 11, 2016 by Harris

Based on a study published on The Lancet, blogger Max Galka created this animated map to illustrate the skyrocketing worldwide increase in obesity from 1975 to 2014. According to the study, in the last 40 years, obesity rates increased from 3.2% to 10.8% for men, and from 6.4% to 14.9% for women. Overall, there were 105 million obese people in 1975; that number rose to 641 million in 2014, with China and US being the leading nations with approximately 90 and 87 million obese people respectively.

28th July: World Hepatitis Day

Posted on July 28, 2016 by Harris

On this year’s World Hepatitis Day, WHO calls for a rapid action to raise awareness of the disease, and increase access to testing and treatment services. Globally, 400 million people are affected by a viral hepatitis infection -a number that represents more than 10 times that of people infected with HIV. According to WHO, it is estimated that approximately 95% of people with chronic hepatitis are unaware of their infection, and less that 1% have access to treatment.

Moreover, WHO has recently published guidelines for the screening and treatment of people with hepatitis C infection, providing recommendations on the preferred regimens, and encouraging the employment of direct-acting antiviral combinations when appropriate.

Picks of the Week: New recommendations for HIV, fibromyalgia and more!

Posted on July 24, 2016 by Harris

Over the last days fellow colleagues shared articles, recommendations, and other noteworthy news on the Among Doctors network. Among them, there is also a very interesting blog post on Psychological And Mental Health by Professor Gabriel Ivbijaro (President of the World Federation for Mental Health and Chair of The World Dignity Project) that worths reading. Let’s have a look at the top picks of these news:

Migraine and risk of cardiovascular disease in women: prospective cohort study
Results of this large, prospective cohort study in women with more than 20 years of follow-up indicate a consistent link between migraine and cardiovascular disease events, including cardiovascular mortality.
EULAR revised recommendations for the management of fibromyalgia
Updated guidelines on fibromyalgia have been published by the European League Against Rheumatism (EULAR).

New recommendations on antiretroviral drugs for HIV infection

Posted on July 14, 2016 by Harris

The International Antiviral Society – USA Panel published their updated recommendations on antiretroviral drugs (ARVs) for the treatment and prevention of HIV infection. With more than 37 million people living with an HIV infection in the world, and 20 million not receiving an antiretroviral therapy, the new guidelines reiterate that all individuals diagnosed with the infection should initiate treatment as soon as possible, regardless of the CD4 cell count.

Moreover, the guidelines reflect on the substantial advances of the ARVs since the last recommendations were released in 2014, recommending initial regimens of two nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI) for most patients. Further points on preexposure and postexposure prophylaxis are discussed, as well as the pharmacoeconomics of the treatment, especially considering the introduction of less-expensive generic formulations.

In the accompanying editorial on JAMA, Kenneth Mayer and Douglas Krakower consider the guidelines a reflection of a successful 35-year research effort and argue that, “Historians may wonder whether the pace of discovery in the early days of the epidemic could have been accelerated, but no one can doubt the signal accomplishments of biobehavioral research and community engagement in forging a common strategy to deal with this global pandemic, one that continues to pose new challenges.”

Picks of the Week: Endometriosis, menopausal symptoms and more!

Posted on July 8, 2016 by Harris

More and more medical news are shared by fellow colleagues on the Among Doctors network on a daily basis. Here’s a selection of those the latest ones:

Diagnostic accuracy of cancer antigen 125 for endometriosis: a systematic review and meta-analysis
CA 125 performs well as a rule-in test facilitating expedited diagnosis and ensuring investigation and treatment can be confidently tailored for the management of endometriosis -however, a negative test is unable to rule out endometriosis.
Use of Plant-Based Therapies and Menopausal Symptoms: A Systematic Review and Meta-analysis
This meta-analysis of clinical trials suggests that composite and specific phytoestrogen supplementations were associated with modest reductions in the frequency of hot flashes and vaginal dryness but no significant reduction in night sweats.
Patient Navigation for Comprehensive Cancer Screening in High-Risk Patients Using a Population-Based Health Information Technology System
Patient navigation as part of a population-based IT system significantly increased screening rates for breast, cervical, and colorectal cancer in patients at high risk for nonadherence with testing. Integrating patient navigation into population health management activities for low-income and racial/ethnic minority patients might improve equity of cancer care.
Multimodal Randomized Functional MR Imaging of the Effects of Methylene Blue in the Human Brain
Using functional MRI, it was found that a single oral dose of methylene blue increased brain activity in the bilateral insular cortex, as well as the prefrontal cortex and parietal and occipital lobes, compared with placebo.
Hepatitis C Core Antigen Testing for Diagnosis of Hepatitis C Virus Infection
The HCVcAg assays with signal amplification have high sensitivity, high specificity, and good correlation with HCV RNA levels greater than 3000 IU/mL and have the potential to replace NAT in settings with high HCV prevalence.
Effect of Escitalopram on All-Cause Mortality and Hospitalization in Patients With Heart Failure and Depression
Chronic systolic heart failure patients treated for 18 months with escitalopram, an SSRI, did not demonstrate significantly reduced all-cause mortality.
Comparative efficacy of simultaneous versus sequential multiple health behavior change interventions among adults
There is limited evidence regarding the relative effectiveness of sequential and simultaneous approaches.

Picks of the Week: The USPSTF advises on colorectal cancer and syphilis screening

Posted on June 28, 2016 by Harris

During the past weeks two important recommendations were published from the US Preventive Services Task Forse (USPSTF) on the screening for colorectal cancer and syphilis. Let’s have a look at them, alongside other news that our members shared in the Among Doctors community:

The US Preventive Services Task Force (USPSTF) published its recommendations on screening for colorectal cancer
The USPSTF recommends screening for colorectal cancer starting at age 50 years and continuing until age 75 years (A recommendation).
Screening for Syphilis: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force
Screening HIV-positive men or MSM for syphilis every 3 months is associated with improved syphilis detection. Treponemal or nontreponemal tests are accurate screening tests but require confirmation.
Exercise during pregnancy protects against hypertension and macrosomia: randomized clinical trial
Maternal exercise may be a preventative tool for hypertension and excessive GWG, and may control offspring size at birth while reducing comorbidities related to chronic disease risk.
Intensive Blood-Pressure Lowering in Patients with Acute Cerebral Hemorrhage
The treatment of participants with intracerebral hemorrhage to achieve a target systolic blood pressure of 110 to 139 mm Hg did not result in a lower rate of death or disability than standard reduction to a target of 140 to 179 mm Hg.
Pharmaceutical Industry–Sponsored Meals and Physician Prescribing Patterns for Medicare Beneficiaries
Receipt of industry-sponsored meals was associated with an increased rate of prescribing the brand-name medication that was being promoted. The findings represent an association, not a cause-and-effect relationship.
Increased versus stable doses of inhaled corticosteroids for exacerbations of chronic asthma in adults and children
Current evidence does not support increasing the dose of ICS as part of a self initiated action plan to treat exacerbations in adults and children with mild to moderate asthma. Increased ICS dose is not associated with a statistically significant reduction in the odds of requiring rescue oral corticosteroids for the exacerbation, or of having adverse events, compared with a stable ICS dose.

Screen for colorectal cancer, urges USPSTF

Posted on June 19, 2016 by Harris

The US Preventive Services Task Force (USPSTF) recently published its recommendations on screening for colorectal cancer on JAMA, concluding that screening is beneficial in average-risk, asymptomatic adults starting at age 50 and continuing until age 75 years (A recommendation). In adults aged 76 to 85 years, the decision should take into consideration the health and history of the patient (C recommendation).

Screening for colorectal cancer can reduce mortality, whichever strategy is employed, says the USPSTF. Seven different screening approaches are included in the recommendations, despite their difference in effectiveness and potential harm: colonoscopy, fecal immunochemical testing for occult blood (FIT), multitargeted DNA stool test (FIT-DNA), guaiac-based fecal occult blood test, sigmoidoscopy, sigmoidoscopy with FIT, and CT colonography. The economic impact of such a screening is not addressed either.

Unrestricted-calorie, high-vegetable-fat Mediterranean diet associated with no weight gain

Posted on June 7, 2016 by Harris

In a study published yesterday in The Lancet Diabetes & Endocrinology, Ramon Ostrich and colleagues reported on the Spanish PREvención con DIeta MEDiterránea (PREDIMED) randomized controlled trial and on the long-term weight change. In their five-year intervention, nearly 7500 asymptomatic men and women with type 2 diabetes mellitus or more than two cardiovascular risk factors were randomly assigned to receive either one of the two unrestricted-calorie Mediterranean diets (one supplemented with extra-virgin olive oil and one supplemented with nuts) or the control diet which included advice to reduce dietary fat.

The authors reported that although the dietary fat consumption was higher for the participants of the Mediterranean diets, in the five-years follow-up not only was there no weight gain, but they even noticed some evidence of decrease in the weight and waist circumference. The results of the study support the hypothesis that restricting calorie intake of healthy fats does not contribute to bodyweight maintenance.
