first_imgStudy describes incidence, risk factors for MDR Enterobacteriaceae in kidsA study yesterday in BMC Infectious Diseases shows that critically ill children with tracheal Enterobacteriaceae infection are at risk for multidrug-resistant (MDR) infections.The retrospective, single-center analysis was performed on ventilated patients admitted to the pediatric intensive care unit of the University Children’s hospital in Tubingen, Germany, from 2005 to 2014. While mechanically ventilated pediatric patients are known to be at risk for tracheal colonization with MDR Enterobacteriaceae, the underlying risk factors are poorly understood. The investigators were looking to determine the incidence of children with suspected MDR infection and the predisposing risk factors.During the study period, 167 Enterobacteriaceae isolates were obtained from the lower respiratory tracts of 123 intubated patients. Of those isolates, 116 (69%) were susceptible and 51 (31%) were identified as MDR Enterobacteriaceae. The most prevalent isolates were Enterobacter spp, followed by Escherichia coli and Klebsiella spp. The most prevalent MDR organisms were E coli, Klebsiella, and Enterobacter spp.Using a classification and regression tree (CRT) analysis to predict risk factors, the investigators determined that antibiotic pre-treatment for more than 7 days increased the risk of infection with an MDR isolate by 62%. In addition, they found that gastrointestinal comorbidity increased the chance of MDR infection from 25% to 40% in patients who received less than 7 days of antibiotic therapy.”Collectively, our results imply that early identification of patients at risk, rapid microbiological diagnostics and tailored antibiotic therapy are essential to improve management of critically ill children infected with Enterobacteriaceae,” the authors write.Feb 21 BMC Infect Dis studyResearchers report MCR-1 in pets, pet food in ChinaAbout 9% of pets and 20% of pet food samples tested in Beijing, China, contained the MCR-1 gene, which confers resistance to the last-resort antibiotic colistin, according to a study yesterday in Emerging Infectious Diseases.An international team of experts tested 566 Enterobacteriaceae isolates collected from cats and dogs via nasal and rectal swabs in the city from 2012 through 2016. Of the total, 49 (8.7%) of the isolates harbored the MCR-1 gene, which was first reported late last year in a 50-year-old man in China. The gene was found on 47 E coli isolates and 2 Klebsiella pneumonia samples. The overall count of colistin-resistant isolates was 79, mostly E coli.The researchers also isolated the MCR-1 gene from 1 of 25 Enterobacteriaceae samples collected from 32 nasal swabs from pet owners. The isolate had the same genetic fingerprint as 5 of the pet samples.In addition, the team tested 35 dog and cat food samples, 7 of which (20%) were positive for MCR-1, signifying a possible source for the animal infections.The authors noted that colistin is not used to treat companion animals in China, and the pets tested had minimal to no contact with food-producing animals that might have been treated with the drug. They conclude, “Because of frequent and close contact between humans and companion animals, our study proposes that opportunities exist to transmit colistin-resistant Enterobacteriaceae to and from both groups.”Feb 21 Emerg Infect Dis study Study: Xpert TB test not tied to increased rates of second-line treatmentA South African study yesterday concluded that the Xpert MTB/RIF tuberculosis (TB) test was associated with a reduction in treatment delay from a median of 44 days in 2011 to 22 days in 2013 for patients with drug-resistant TB but did not significantly improve the proportion of patients receiving proper antibiotics. The study appeared in PLoS Medicine.South African and Dutch researchers aimed to assess second-line antibiotic treatment before and after the Xpert MTB/RIF test was implemented in South Africa, so they analyzed data from 2011 and 2013 on more than 5,000 TB cases resistant to the key first-line drug rifampin.The investigators found that treatment delays were halved after Xpert implementation, from 44 to 22 days. But they found no difference in those who started second-line drug treatment within 6 months of diagnosis by Xpert (62%) and those diagnosed by other methods (64%). They also found substantial variation across the country’s nine provinces in both the rate of second-line 6-month treatment initiation and the median time to treat.Although Xpert appeared to have not improved rates of appropriate treatment, the authors wrote, “given improved case detection, a larger proportion of the total population of individuals with rifampicin-resistant TB will receive treatment.” They added, “Further strategies to improve linkage to treatment for all patients diagnosed with rifampicin-resistant TB are required.”Feb 21 PLoS Med studylast_img read more

Proposed drug rehab facility causes stir

Davis was not involved with the letter. “I think it was a fear factor,” Davis said. “And I think the Scientology scared people, which was sad.” Plans for the property include converting and upgrading 11 existing buildings into three dormitories, kitchen and dining area, classrooms, staff facilities, a 29-vehicle parking lot and swimming pool, according to a Regional Planning Commission’s staff report. The facility, with about 11 employees, would be designed to treat up to 66 adults, whose average stay would be three to four months. Traffic to the area would be minimal from the proposed facility at 36491 Bouquet Canyon Road, according to the report, because clients will not be allowed to have cars. Instead they will be transported by van. In addition, visitors would be discouraged, so as not to interfere with treatment. If the application gets the nod from commissioners, the staff has recommended 10 years of use under the permit. The proposed facility is compatible with zoning for the area on Bouquet Canyon Road and with the permit, according to the staff report. The Narconon program was started in 1966 by William Benitez, an inmate in Arizona State Prison, who applied principles from a book by L. Ron Hubbard to his heroin addiction. Today there are Narconon rehabilitation and education centers around the world, according to the nonprofit’s Web site. The facility is also asking for permission to remove two oak trees from the property. One has fallen down, and the other is decaying and endangers a nearby building. Catherine L. Savage, a Narconon Southern California representative, did not return phone calls for comment. James Bell, a planner with the Regional Planning Commission, referred calls to a supervisor who is out of the office until Wednesday when the hearing takes place.

SAUGUS – A Scientology-based treatment facility hopes to soon open shop on Bouquet Canyon Road to treat adults with drug and alcohol addictions. Representatives from Narconon Southern California are scheduled to appear today before the county’s Regional Planning Commission for a permit to develop the facility on the 30.4-acre site, once home to a children’s boarding school. The Leona Valley Town Council wants the application denied. In a letter sent last month to the commission, the community group cited concerns about the impact the center would have on the environment and local welfare. last_img read more
