CLSI’s M100 Annual Updates Webinar

On February 20 and 21, CLSI will host its annual M100 updates webinar. This webinar will be moderated by Janet Hindler, MCLS, MT(ASCP), F(AAM) and presented by Romney M. Humphries, PhD, D(ABMM) and Audrey Schuetz, MD, MPH, FCAP. The material presented will be the same on both days and will help your lab staff identify the major changes found in the updated edition of CLSI document M100.

Applying Fluoroquinolone Pharmacokinetics, Pharmacodynamics, and Updated Clinical Breakpoints for Gram-Negative Pathogens to Determine Optimal Dosing

Antimicrobial-resistant bacteria are responsible for significant morbidity, mortality, and excess healthcare costs, and their prevalence is increasing at a rate faster than the antimicrobial development pipeline. FDA-approved antimicrobial doses represent estimates across a patient population in order to maximize generalizability and probability of clinical effect as it would apply to “most” patients. Unfortunately, the increase in bacterial resistance and medical complexity of our patients means that these population estimates no longer apply to “most” patients, or at least not to the patients in whom optimizing antimicrobial doses matters the most. Fortunately, the principles of antimicrobial pharmacokinetics (PK) and pharmacodynamics (PD) can help optimize dosing regimens and tailor therapy for each patient individually.

The Importance of Prenatal and Newborn Screening

Prenatal screening tests are performed during pregnancy to determine the likelihood of a baby having specific birth defects. Most tests are performed during the first or second trimester and are noninvasive. A screening can only provide information about the possibility that the condition is present. When screening is positive, further confirmatory diagnostic testing is performed.

January is National Birth Defects Prevention Month

January is National Birth Defects Prevention Month. The theme for 2019 is “Best for You. Best for Baby.” The National Birth Defects Prevention Network Education and Outreach Committee has developed materials and resources to assist organizations interested in raising awareness during National Birth Defects Prevention Month.

January is National Cervical Health Awareness Month

The United States Congress has designated January as Cervical Health Awareness Month. Nearly 13,000 women in the United States are diagnosed with cervical cancer each year. Cervical cancer is preventable with vaccination and appropriate screening.

Celebrate National Hand Washing Week

National Hand Washing week is celebrated the week of December 2nd through December 8th 2018 and is a great way to promote better hygiene and reduce illness.

World AIDS Day

December 1 is the 30th anniversary of World AIDS Day. This year’s theme is “Know your status”. World AIDS Day originated at the 1988 World Summit of Ministers of Health on Programs for AIDS Prevention. Since then, every year United Nations agencies, governments, and communities join forces to campaign around specific themes related to AIDS.

Clostridium difficile Awareness Month

November is Clostridium difficile Awareness Month. C. diff was associated with nearly 30,000 deaths in 2011. Historically thought of as a problem mostly confined to hospitals and nursing homes, C. diff rates in the community seem to be on the rise. Antibiotic use is a known factor; hospitalization is another. Clostridial species can resist disinfectants, which is why so many infections occurred in hospitals and nursing homes.

Prevention of Specimen Labeling Errors in the Lab

Accurate specimen identification is critical for quality patient care. Improperly identified specimens can result in delayed diagnosis, additional laboratory testing, treatment of the wrong patient for the wrong disease, and severe transfusion reactions. Specimen identification errors have been reported to occur at rates of 0.1% to 5%.

Prematurity Awareness Month and Newborn Screening

An estimated 15 million babies around the world are born premature each year and more than one million of them do not survive. Although the United States has seen sustained improvement in its preterm birth rate, it has one of the highest rates of preterm birth of any industrialized country.
