Rates of unvaccinated children have quadrupled since 2001


The Centers for Disease Control and Prevention (CDC) reports that a small but increasing number of children in the United States are not getting some or all of their recommended vaccinations with 1.3 percent of children born in 2015 having not received any vaccinations, up from 0.3 percent in 2001. 

Though the number remains small it is something that CDC is concerned about.  CDC data show children in rural areas and those without insurance had significantly higher rates of not being vaccinated.  The CDC estimates that 100,000 young children have not had a vaccination against any of the 14 diseases for which vaccines are recommended. 

Although 70 percent of the children have been vaccinated the new estimate of 1.3 percent of the children born in 2015 were completely unvaccinated is very concerning because young children are especially vulnerable to complications from vaccine-preventable diseases, some of which can be fatal.

Screening for Cervical Cancer



The U.S. Preventive Services Task Force issued new guidelines that were published in JAMA regarding cervical cancer screening, suggesting that women can get a test that looks for the human papilloma virus.

The task force recommends that screening should begin for women age 21-29 with a Pap test every three years, which they may continue from age 30 to 65, or they can get screened every five years with a test that looks for the high-risk types of HPV that cause cervical cancer or get both tests every five years.

The USPSTF guidelines say that women over 30 can safely wait five years between cervical cancer screenings thus reducing false alarms that lead to invasive follow-up tests and unnecessary treatment.

The new guidelines “are based on a now-solid body of evidence showing that almost all cases of cervical cancer are caused by the human papilloma virus.

Sleeping more than eight hours increases risk of death from heart disease and/or stroke.


In a study by Kwok et al published in the Journal of the American Heart Associationthe researchers found that sleeping more than eight hours a night may increase the risk of death from heart disease or stroke, while sleeping fewer than seven hours did not affect one’s likelihood of death.

The authors searched MEDLINE and EMBASE databases and identified seventy‐four studies that included 3,340,684 participants.  In those studies 242,240 deaths were reported among 2,564,029 participants. Self‐reported duration of sleep of more than 8 hours was associated with a moderate increased risk of all‐cause mortality, with risk ratio, 1.14 (1.05–1.25) for 9 hours, risk ratio, 1.30 (1.19–1.42) for 10 hours, and risk ratio, 1.47 (1.33–1.64) for 11 hours. No significant difference was identified for periods of self‐reported sleep of less than 7 hours, whereas similar patterns were observed for stroke and cardiovascular disease mortality. Subjective poor sleep quality was associated with coronary heart disease (risk ratio, 1.44; 95% confidence interval, 1.09–1.90), but no difference in mortality and other outcomes.
The authors concluded that divergence from the recommended 7 to 8 hours of sleep is associated with a higher risk of mortality and cardiovascular events.

Moderate alcohol consumption increases the risk of cardiovascular events and death.


A study by Wood et al published in Lancet suggests that the risks of drinking vis-à-vis cardiovascular events and death are significant.

The authors analyzed data from 599 912 current drinkers without previous cardiovascular disease.  They characterized dose–response associations per 100 gram per week of alcohol across 83 prospective studies, adjusting for age, sex, smoking, and diabetes.

They recorded 40 310 deaths and 39 018 incident cardiovascular disease events among the 599 912 drinkers in high-income countries that were included in their study. For all-cause mortality, they recorded a positive and curvilinear association with the level of alcohol consumption, with the minimum mortality risk at or below 100 g per week. Alcohol consumption was roughly linearly associated with a higher risk of stroke, coronary disease excluding myocardial infarction, fatal hypertensive disease and fatal aortic aneurysm. By contrast, increased alcohol consumption was log-linearly associated with a lower risk of myocardial infarction. In comparison to those who reported drinking >0–≤100 g per week, those who reported drinking >100–≤200 g per week, >200–≤350 g per week, or >350 g per week had lower life expectancy at age 40 years of approximately 6 months, 1–2 years, or 4–5 years, respectively.
The threshold for lowest risk of all-cause mortality was about 100 gram per week or one drink per day. The study concludes that there are no overall health benefits from moderate drinking which according to current guidelines is 196g per week or two drinks per day.

An egg a day reduces cardiovascular and stroke risk


Qin et al in a study publish by British Medical Journal examined survey data from individuals that were followed for nine years and found that compared to people who never ate eggs, individuals who ate an average of 0.76 eggs per day were at less risk to develop cardiovascular diseases (CVD) and less likely to die from ischemic heart disease (IHD), major coronary events, hemorrhagic and ischemic strokes.
Among 461 213 participants free of prior cancer, CVD and diabetes, a total of 83 977 CVD incident cases and 9985 CVD deaths were documented, as well as 5103 major coronary events (MCE).
 Among the participants 13.1% reported daily consumption (usual amount 0.76 egg/day) and 9.1% reported never or very rare consumption (usual amount 0.29 egg/day). Compared with non-consumers, daily egg consumption was associated with 11 percent lower risk of developing CVD disease and cut the risk of stroke by 26 percent while also decreasing the risk of dying from CVD conditions to 18 percent compared to non-consumers.  Daily consumers also had a 28% lower risk of hemorrhagic stroke death compared to non-consumers.
The researchers concluded that a moderate level of egg consumption (up to <1 egg/day) was significantly associated with lower risk of CVD and largely independent of other risk factors.

Dairy Consumption does not Increase Risk of Cardiovascular Attacks



Research published in the European Journal of Epidemiology suggests that consumption of dairy products does not increase the risk of cardiovascular events or death. 

The investigators analyzed results from 29 medical studies carried out over the last 35 years, using information based on almost 938,465 participants and 93,158 cases of mortality, 28,419 cases cardiovascular heart disease (CHD) and 25,416 cardiovascular disease (CVD) cases. No associations were found for total (high-fat/low-fat) dairy, and milk with the health outcomes of mortality, CHD or CVD. Inverse associations were found between totally fermented dairy such as sour milk products, cheese or yogurt; per 20 g/day with mortality and CVD risk. Further analyses of individual fermented dairy of cheese and yogurt showed cheese to have a 2% lower risk of CVD per 10 g/day, but not yogurt. 

In conclusion data from prospective cohort studies demonstrated that consumption of dairy products – even high-fat ones demonstrated neutral associations between dairy products and cardiovascular events as well as all-cause mortality.

Dog Ownership Decreases Risk of Dying from Cardiovascular Disease


Mubanga et al in a paper published in Scientific Reports suggest that having a dog could be linked to lower risk of dying from cardiovascular disease.

The investigators analyzed health records of 3.4 million people in Sweden. The data indicated that people who owned a dog were less likely to have cardiovascular disease or die from any cause during the 12 years covered by their research.

In single- and multiple-person households, dog ownership (13.1%) was associated with lower risk of deathwith the protective effect being more prominent for people living alone, who have been found to have a higher risk for early death than those who live with other people.  Ownership of hunting breed dogs was associated with lowest risk of CVD.

The protective effects may be due to dog owners are more physically active or due to increased well being and social contacts or effects of the dog on the bacterial microbiome of the owner.

In conclusion, dog ownership appears to be associated with lower risk of CVD in single-person households but also lower mortality in the population at large.
