Point-of-care (POC) or near patient testing for infectious diseases is a rapidly expanding space that is part of an ongoing effort to bring care closer to the patient. Traditional POC tests were known for their limited utility, but advances in technology have seen significant improvements in performance of these assays. The increasing promise of these tests is also coupled with their increasing complexity, which requires the oversight of qualified laboratory-trained personnel.Biosafety risks are prevalent in all areas of the clinical laboratories. Clinical laboratorians have become accustomed to accepting these risks. Bromelain When an emerging pathogen appears, the concerns become elevated. Since the appearance of Ebola virus in the United States in 2014, biosafety practices have made progress. A recent Association of Public Health Laboratories survey shows that clinical laboratories are unprepared for current and emerging biosafety challenges. This article focuses on the biosafety program that clinical laboratory leaders should build to meet the needs of clinical laboratories; biosafety challenges of automated laboratory systems, facilities, personnel, and practices; and the relationship with occupational health.Endemic species of coronavirus (HCoV-OC43, HCoV-229E, HCoV-NL63, and HCoV-HKU1) are frequent causes of upper respiratory tract infections. Three highly pathogenic coronaviruses have been associated with outbreaks and epidemics and have challenged clinical microbiology laboratories to quickly develop assays for diagnosis. Their initial characterization was achieved by molecular methods. With the great advance in metagenomic whole-genome sequencing directly from clinical specimens, diagnosis of novel coronaviruses could be quickly implemented into the workflow of managing cases of pneumonia of unknown cause, which will markedly affect the time of the initial characterization and accelerate the initiation of outbreak control measures.Recent improvements in next-generation sequencing technologies have enabled clinical laboratories to increasingly pursue pathogen genomics for infectious disease diagnosis. Clinical laboratories can also benefit from whole-genome sequence characterization of cultured isolates, helping to resolve infection prevention questions pertaining to pathogen outbreaks and surveillance. Metagenomic sequencing from primary specimens can also provide laboratories with an unbiased universal test for situations where traditional methods fail to identify infectious etiologies despite, high clinical suspicion. Here, the most useful applications of whole-genome sequence and metagenomic sequencing are summarized, as are the main advantages, limitations, and considerations for building an in-house clinical genomics program.Antimicrobial susceptibility testing (AST) is now, more than ever, a critical role of the microbiology laboratory. Several factors limit its application for patient care and antimicrobial resistance epidemiology, including time to results, requirements for pure cultures, and high starting concentration of bacteria. This review discusses the global status of AST and new phenotypic and genotypic methods in late-stage development or that are new to market.Planning for a new laboratory is exciting and daunting. The project's success starts with an agreed on vision and scope as defined by key stakeholders. In addition to the work of architects and building professionals, such projects require major investment in upfront thought, time, and commitment from laboratory directors, supervisors, and technologists who will use the space. Incorporating design features critical to efficient and flexible workflow as required to meet growing and changing needs will extend the lifetime of the space. Open floor plans may challenge some sensibilities and biosafety concerns but are the vogue for BSL-2 laboratories.Syndromic panels have allowed clinical microbiology laboratories to rapidly identify bacteria, viruses, fungi, and parasites and are now fully integrated into the standard testing practices of many clinical laboratories. To maximize the benefit of syndromic testing, laboratories must implement strict measures to ensure that syndromic panels are being used responsibly. This article discusses commercially available syndromic panels, the benefits and limitations of testing, and how diagnostic and laboratory stewardship can be used to optimize testing and improve patient care while keeping costs at a minimum.The optimal care of septic patients depends on the successful recovery of clinically relevant microorganisms from blood cultures and the timely reporting of organism identification and antimicrobial susceptibility testing (AST) results. Many preanalytic factors play a critical role in culturing microorganisms, and advancements in blood culture instrument technology have reduced the time to positive results. Additionally, rapid organism identification and AST results directly from positive blood culture broth via new methods help to further shorten the time from empiric to targeted treatment. This article summarizes the current state of blood culture methods, including preanalytic, analytical, and postanalytic factors that are available to clinical microbiology laboratories.

Patients seropositive HIV and AIDS represent a group of patients who experience longer longevity at the expense of effective therapies for infection control and related opportunistic diseases. However, the prolonged use of these drugs is often associated with adverse events, which theoretically may influence dental management and the long-term stability of dental implants. The objective of this study was to prospectively evaluate a group of HIV-positive people from a previous study who had received dental implants for 12 years after oral rehabilitation and functional loading.

Nine patients with a total of 18 implants participated in this study. Viral load was undetectable in 8 patients, with 1 who had 48 copies/milliliter. The cluster of differentiation 4 T lymphocyte count ranged from 227 through 1,000 cells/cubic millimeter, mean (standard deviation [SD]) 564 (271.13) cells/mm

. Five of the 9 (55.5%) patients had visible plaque, and 5 (55.5%) had bleeding on probing with no implant mobility. Radiographs obtained at 6 months, 12 months, and 12 years of functional loading showed mean (SD) marginal bone losses of 0.
