CDC mulling expanded screening for coronavirus; spread risk still low

Published

on

Jan. 27 (UPI) — Centers for Disease Control and Prevention on Monday raised its travel warning for China to its highest alert level as they consider increased screenings for travelers from the Asian nation that is dealing with an increasing number of confirmed cases of the 2019 novel coronavirus.

The agency raised its travel advisory to a level 3, warning U.S. citizens to avoid all nonessential travel to the country while urging those who must visit China to avoid sick people, animals, animal market and animal products.

Meanwhile, the agency told reporters Monday that there have been no new cases beyond the five currently known and that 110 people from 26 states are currently being tested for the virus.

People coming to the United States from China have been funneled through five airports during the last week-and-a-half, and the State Department on Friday issued a travel advisory and ordered Americans to leave Wuhan, China, where the outbreak started.

The State Department also issued an updated travel advisory encouraging Americans to avoid all nonessential travel to China and to not travel to the Hubei province, where Wuhan is located.

As of Monday, there have been no confirmed reports of human-to-human transmission in the United States. Chinese officials caused a bit of a firestorm over the weekend when they suggested that human-to-human transmission may be possible during the 2- to 14-day “incubation” period, when those sickened are still asymptomatic.

However, Nancy Messonnier, director of the agency’s National Center for Immunization and Respiratory Diseases, said the CDC has “no clear evidence” of that at this point.

“At this time in the U.S., the virus is not spreading throughout the community,” she said. “The risk remains low at this time.”

Chinese officials canceled all flights last week out of Wuhan, the city that has been ground zero for the virus.

Messonnier said that the CDC, working with local departments of health, is still screening travelers at five airports across the country. The agency has opted for a particular focus on those arriving from Hubei, the province in central China where Wuhan is located, or those who have had confirmed contact with someone known to have been sickened by the virus.

To date, screeners have checked more than 2,400 travelers, according to Messonier. The numbers of those detained for screening at the airports has been steadily declining, she added, as Chinese officials have imposed travel restrictions on the affected region.

“We are considering a broadening of that screening” to include all travelers from China, Messonnier said.

U.S. Vice President Mike Pence told guests during a Lunar New Year event that the United States was conducting screenings at 20 U.S. airports that received 90 percent of all passengers from China and any passengers who are ill will be subject to further screenings.

“And so let me say once again, here in our country, we’ve taking strong steps to see to the health and the wellbeing of the American people,” he said. “But as President [Donald] Trump made clear today, the United States of America stands ready — stands ready to assist the people of China and around the world as they deal with this virus.”

The United States still has only five confirmed cases of 2019 novel coronavirus, or 2019 n-CoV, as of Monday. However, 110 additional people from 26 states are currently being tested for the virus, and 32 others have been tested, and found to be negative.

They remain in isolation until test results are in. The process takes approximately one day, Messonier noted, as the CDC is still recommending that samples be tested in its laboratories in Atlanta.

The agency has developed a testing protocol for local labs, which it made public over the weekend. It also plans to develop testing “kits,” which it will distribute to health departments in “priority states” within the next one to two weeks.

However, the agency will continue to recommend that all testing be performed in its labs to ensure accuracy.

“Speed is important, but accuracy is more important,” Messonier explained.

2 in 3 parents would send kids to school in the fall, survey finds

Published

on

About two-thirds of U.S. parents say they’ll send their kids to school again this fall, and most also support COVID-19 testing and social distancing policies for schoolchildren, a new survey finds.

Among parents, only about 12 percent said they would not send at least one of their kids to school, while 21 percent were still uncertain about their decision. Many are waiting to hear more about their schools’ plans.

Many parents said they had no choice but to send their children to school because they had to work.

For many families, a surge in COVID-19 cases would make them reconsider sending children to school, the survey found.

Most did support measures to safeguard kids against the new coronavirus.

Those measures could include fewer children on buses, daily temperature screening, alternating classroom and online learning, testing school staff and requiring staff and older kids to wear masks, researchers report.

For the report, researchers from the Susan B. Meister Child Health Evaluation and Research Center at the University of Michigan, Ann Arbor, surveyed nearly 1,200 parents in Michigan, Ohio and Illinois in June.

“Families are facing a challenging decision regarding whether to send their children to school for in-person classes in the middle of the COVID-19 pandemic,” said researcher Dr. Kao-Ping Chua, a pediatrician at Michigan Medicine C.S. Mott Children’s Hospital.

“On the one hand, sending children to school could increase the risk of COVID-19 among children and family members. On the other hand, children who don’t return to in-person school may experience disruptions in their education,” Chua said. “Some families simply don’t have a choice because they need to go to work.”

According to the survey, 75 percent of parents supported daily temperature checks and testing of kids if one tested positive for COVID-19.

Over 60% supported limiting the number of kids on buses, alternating between in-person and virtual classes, staggering arrival and pick-up times, and random weekly COVID-19 testing for staff.

Half supported random weekly COVID-19 testing of kids and having children eat meals in classrooms, not in cafeterias.

Most parents supported face masks for staff and middle and high school students, but not for younger children, especially kindergarten through second grade.

There wasn’t much support for closing playgrounds and halting all extracurricular activities.

“Preferences for the number and types of measures vary among parents,” Chua said in a university news release. “But they broadly agree with the notion that schools should take steps to keep children as safe as possible.”

Study: Deep brain stimulation may slow Parkinson’s disease

Published

on

Data from a five-year clinical trial is adding to growing evidence that deep brain stimulation, or DBS, can slow the ravages of Parkinson’s disease.

Researchers at Vanderbilt University Medical Center in Nashville, Tenn., said that the therapy appears to curb any worsening of tremor and other symptoms, as well as lessening a patient’s need for medications.

“Parkinson’s is relentless,” senior study author Dr. David Charles, Vanderbilt professor and vice-chair of neurology, said in a medical center news release. “There’s nothing that slows down its progression.”

However, “with this pilot study, we’ve shown that if DBS is implanted early it’s likely to decrease the risk of progression, and if this is borne out in our larger study it would be a landmark achievement in the field of Parkinson’s disease,” he said.

The new study was small — just 30 patients. Between 2006 and 2009, the participants were randomly selected to receive either the optimal Parkinson’s disease drug therapy, or optimal drug therapy plus DBS.

In DBS, doctors surgically implant a pair of ultra-thin electrodes deep into the brain. The electrodes target electric pulses to the subthalamic nucleus, a small cluster of neurons. Similar to a heart pacemaker, the device is powered by a small battery implanted under the skin near the patient’s collarbone.

After five years, patients who’d received only the drug therapy had a five times higher risk of progression of “rest tremor” — a key Parkinson’s symptom — compared to those patients who’d gotten the electrode implants as well as drug therapy, the researchers reported.

What’s more, patients who got DBS needed far fewer meds going forward.

“Patients who were randomized to receive early optimal drug therapy [only] had 15-fold greater odds of needing multiple types of Parkinson’s disease medications,” study project leader Mallory Hacker, an assistant professor of neurology at the medical center, said in the news release.

The evidence of reductions in another key Parkinson’s symptom — worsening motor symptoms — did not reach statistical significance, the researchers said, although there was a trend suggesting a benefit from DBS.

Still, this study was small and the results should be considered preliminary, Charles said.

“While this is an incredibly exciting finding, patients and physicians should not change clinical practice at this time,” Charles said. “What this pilot study is most clearly telling us is that the new FDA-approved Phase III study must be done to definitively determine whether DBS slows the progress of Parkinson’s disease when implanted in the very earliest stages.”

Dr. David Weintraub directs functional neurosurgery at North Shore University Hospital in Manhasset, N.Y. Reading over the study he said that it “provides evidence that the use of DBS surgery early in the course of Parkinson’s disease can have meaningful benefits for patients compared to medication alone.”

Weintraub agreed that the findings remain preliminary. However, he said that positive results from a “larger scale, multicenter trial could potentially lead to the adoption of DBS surgery even earlier in the course of Parkinson’s disease treatment, which would be a very significant advance in the field.”

The study was published in the July issue of Neurology. It received funding from the U.S. National Institutes of Health, the Michael J. Fox Foundation for Parkinson’s Research, and Medtronic, Inc., the manufacturer of the DBS system used in the trial.

Study finds differences in heart failure trends between former East, West Germany

Published

on

July 1 (UPI) — Differences in heart health between people in the eastern and western parts of Germany show a long-term effect of the Berlin Wall on the country, according to new findings presented Wednesday on HFA Discoveries.

Germany was divided in the aftermath of World War II, and different healthcare structures developed in East and West Germany. The country became unified again in 1990, but new research shows effects of the decades-long separation persist, researchers say.

From 2000 to 2017, the absolute number of hospital admissions due to heart failure throughout Germany increased continuously by nearly 94 percent — to approximately 465,000 from just under 240,000 — researchers said.

However, the increase was much higher, at 119 percent, in the region that once encompassed East Germany, compared to just over 88 percent in the region once known as West Germany, they said.

Study co-author Marcus Dörr, a professor at the University Medicine Greifswald in Germany, said differences between the two regions in prevalence of heart failure risk factors may explain the findings.

“In fact, previous research has shown that, for example, hypertension, diabetes and obesity are much more common in East than in West Germany,” Dörr said in a press release.

In addition, lingering differences in patient care, as well as in the management of healthcare systems between the two regions, still might exist, Dörr said.

In general, heart failure is the most common reason for hospital admissions in the United States, Germany and much of the world, he said.

For their research, Dörr and his colleagues analyzed data from the Federal Health Monitoring project, an annual census of routine health data in Germany, for 2000 through 2017.

Heart failure was the leading cause of disease-related hospitalization in Germany in 2017, they found.

However, heart failure hospitalization rates nearly doubled in the former East Germany — to 2.9 percent from 1.5 percent — from 2000 to 2017, while it increased to 2.2 percent from 1.4 percent in the former West Germany over the same period, the researchers said.

While the overall length of hospital stays decreased continuously over the same period, the total number of heart failure-related hospital days increased by 51 percent in East Germany, compared to 35 percent in West Germany.

In 2017, heart failure was by far the leading cause of in-hospital death across Germany, accounting for 8.2 percent of deaths, they found.

However, in the region that once was East Germany, heart disease caused 65 deaths per 100,000 inhabitants in 2017, compared to 43 deaths per 100,000 inhabitants in the former West Germany, they said.

The differences may have to do with the average age of people in East Germany — four years older than it is in the West — but the differences in heart failure-related parameters were similar after standardization, the researchers said.

Before reunification in 1990, East and West Germany had distinct healthcare systems, Dörr said. The system in East Germany was essentially run by the state, with less than 1 percent of physicians working in private practice, and there were often shortages of technical equipment, he said.

“Since 1990, both regions have the same federal healthcare system with more physicians in private practice and similar clinical care pathways” Dörr said. “More research is needed to explain the huge differences observed between East and West Germany.”
