Biomarkers for the clinical development of antiviral therapies.

With the morbidity and mortality associated with the COVID-19 pandemic that we are witnessing this year, the risks posed by emerging viral diseases to global health are all too obvious. This pandemic highlights the importance of antiviral drug discovery, which targets emerging viral pathogens, as well as existing pathogenic viruses that undergo continuous evolution. Drug discovery and development is a long and resource intensive process; however, the use of biomarkers can accelerate clinical development of antivirals by providing information regarding diagnosis of specific viral infections, status of infection, potential safety parameters, and antiviral responses.

Pharmacokinetics, Safety, and Efficacy of Glecaprevir/Pibrentasvir in Children With Chronic HCV: Part 2 of the DORA Study.

Background And Aims: Glecaprevir/pibrentasvir (GLE/PIB) has shown high efficacy and safety in chronic HCV-infected adults and adolescents; data in children were limited. DORA part 2 is a phase 2/3, nonrandomized, open-label study evaluating the pharmacokinetics, efficacy, and safety of a pediatric formulation of GLE and PIB in children ages 3 to < 12 years.

Approach And Results: Children with chronic HCV infection, genotype 1-6, with or without compensated cirrhosis, were divided into three cohorts by age-cohort 2 (9 to < 12 years), cohort 3 (6 to < 9 years), and cohort 4 (3 to < 6 years)-and given weight-based doses of GLE and PIB for 8, 12, or 16 weeks.

Glecaprevir/Pibrentasvir Treatment in Liver or Kidney Transplant Patients With Hepatitis C Virus Infection.

Unlabelled: Well-tolerated, ribavirin-free, pangenotypic hepatitis C virus (HCV) treatments for transplant recipients remain a high priority. Once-daily glecaprevir/pibrentasvir demonstrates high rates of sustained virologic response at 12 weeks posttreatment (SVR12) across all major HCV genotypes (GTs). This trial evaluated the safety and efficacy of glecaprevir/pibrentasvir for patients with chronic HCV GT1-6 infection who had received a liver or kidney transplant.

Multistate US Outbreak of Rapidly Growing Mycobacterial Infections Associated with Medical Tourism to the Dominican Republic, 2013-2014(1).

During 2013, the Maryland Department of Health and Mental Hygiene in Baltimore, MD, USA, received report of 2 Maryland residents whose surgical sites were infected with rapidly growing mycobacteria after cosmetic procedures at a clinic (clinic A) in the Dominican Republic. A multistate investigation was initiated; a probable case was defined as a surgical site infection unresponsive to therapy in a patient who had undergone cosmetic surgery in the Dominican Republic. We identified 21 case-patients in 6 states who had surgery in 1 of 5 Dominican Republic clinics; 13 (62%) had surgery at clinic A.

Predictors of Enteral Autonomy in Children with Intestinal Failure: A Multicenter Cohort Study.

Objectives: In a large cohort of children with intestinal failure (IF), we sought to determine the cumulative incidence of achieving enteral autonomy and identify patient and institutional characteristics associated with enteral autonomy.

Study Design: A multicenter, retrospective cohort analysis from the Pediatric Intestinal Failure Consortium was performed. IF was defined as severe congenital or acquired gastrointestinal diseases during infancy with dependence on parenteral nutrition (PN) >60 days.

Negative pressure wound therapy technologies for chronic wound care in the home setting: A systematic review.

The use of negative pressure wound therapy (NPWT) is increasing in both the inpatient and outpatient settings. We conducted a systematic review on the efficacy and safety of NPWT for the treatment of chronic wounds in the home setting. We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature, up to June 2014.

Clostridium difficile in the Pediatric Population of Monroe County, New York.

Background: Clostridium difficile infection (CDI) incidence in hospitalized children has increased over the past decade and disease has been reported in the community. Therefore, population surveillance that includes nonhospitalized cases is important to accurately estimate the burden of CDI in children. We describe the epidemiology of CDI in the pediatric population of Monroe County, New York.

Resolution of a fungal mycotic aneurysm after a contaminated steroid injection: a case report.

Background: In the past ten years there have been three separate outbreaks of fungal contaminated steroid injections from compounding pharmacies. The 2012 outbreak of central nervous system fungal infections associated with contaminated methylprednisolone produced by a United States compounding pharmacy has led to 750 infections (151 with meningitis and paraspinal infections and 325 cases with paraspinal infections without meningitis) and 64 deaths as of October 23, 2013. Exserohilum rostratum has been the predominant pathogen identified by culture, polymerase chain reaction or antibody tests.

Antimicrobial stewardship in long-term care facilities.

Although antimicrobial stewardship has been shown to improve microbiologic susceptibility patterns, decrease drug toxicities, and lower overall drug costs in the inpatient setting, there are few studies assessing programs in the long-term care (LTC) setting. Implementing antimicrobial stewardship programs in LTC settings can be challenging as the LTC setting houses a unique population of frail and older adults with several preexisting conditions and multiple risk factors for colonization with multidrug-resistant organisms. Antimicrobial stewardship has an important role in decreasing inappropriate antibiotic use, encouraging targeted treatment of specific disease states, and limiting the untoward effects and costs of antimicrobials in this vulnerable population.

Natural history of pediatric intestinal failure: initial report from the Pediatric Intestinal Failure Consortium.

Objective: To characterize the natural history of intestinal failure (IF) among 14 pediatric centers during the intestinal transplantation era.

Study Design: The Pediatric Intestinal Failure Consortium performed a retrospective analysis of clinical and outcome data for a multicenter cohort of infants with IF. Entry criteria included infants <12 months receiving parenteral nutrition (PN) for >60 continuous days.

Use of complementary and alternative medicines by ambulatory patients.

Background: Complementary and alternative medicines (CAM) include a number of different modalities to improve health. The popularity of such healing methods has increased, although reports of problems and adverse effects have also increased. Difficulties have also been identified in communication between patients and their providers.
