Successful use of dalbavancin in the treatment of gram positive blood stream infections: a case series.

BACKGROUND: Dalbavancin is a semisynthetic antibiotic used as an alternative to vancomycin for skin infections and osteomyelitis. Its long half-life decreases length of hospitalizations. This study analyzes the effectiveness of Dalbavancin for bacteremia and infective endocarditis. METHODS: The authors performed a retrospective chart analysis on patients who received Dalbavancin due to being poor candidates for PICC placement, poor candidates for prolonged hospitalization, or who were leaving against medical advice. Their hospitalizations were analyzed and results were compiled using descriptive statistics. RESULTS: Our cohort had 22 patients treated with Dalbavancin for bacteremia and 1 for endocarditis. They were treated with IV antibiotics, typically a regimen of at least vancomycin and a cephalosporin, for a median of 6.5 days prior to receiving Dalbavancin. 20 received one dose, while three received two doses. 22 had confirmed culture clearance and one denied repeat culture. There were no reported side effects from the medication, no readmissions for worsened infection, and no deaths from the infection. 15 patients had follow-up visits within 90 days. CONCLUSIONS: Overall, patients responded well. The lack of readmission to the hospital indicates possible outpatient treatment. This would help decrease cost and comorbidities of long-term hospital stays. These positive results are limited by small sample size and treatment of other antibiotics prior to receiving Dalbavancin. Further research is required to accurately estimate the efficacy of Dalbavancin on bloodstream infections and endocarditis, but these results are promising especially for patients who are not candidates for long term hospitalization or outpatient IV access.

Exercise Counseling in Pregnancy: Do Women Perceive Receiving the Information They Need?

The American College of Obstetricians and Gynecologists recommends that women exercise throughout pregnancy unless they have a condition-related contraindication. This study's purpose was to determine if pregnant women perceive receiving exercise counseling by their providers with details of frequency, intensity, type, and time (FITT principle). Women in 2 postpartum care units of a large health care system were invited to complete a voluntary, anonymous survey regarding whether they received exercise counseling during their prenatal care. Survey results were descriptively reported, stratified by demographic variables, and analyzed using Fisher's exact tests. Of 224 postpartum women surveyed, 130 (58.0%) perceived receiving exercise counseling during pregnancy; 119 (91.5%) did not recall receiving counseling on exercise frequency. Though 165 (73.6%) exercised before becoming pregnant, 64 (38.8%) ceased exercise during pregnancy. Eighty-eight (39.3%) received advice from other sources/non-health care professionals. Privately insured women reported receiving exercise counseling at a higher rate (70.1%) than those on Medicaid (44.8%) or uninsured (40.0%; P = .004). A disproportionate number of pregnant women perceived not receiving adequate prenatal exercise counseling or received incomplete counseling. Women at a socioeconomic disadvantage may be vulnerable. As social determinants of health, structural barriers, and socioeconomic status likely contribute, women may benefit from more targeted inclusive and equitable messaging.

Community-Acquired, Extended-Spectrum ß-Lactamase-Producing and Extensively Drug-Resistant Escherichia coli in a 28-Year-Old Pyelonephritis Patient Lacking Risk Factors.

While Escherichia coli is a common cause of urinary tract infections and pyelonephritis, there are few documented cases of extended-spectrum ß-lactamase (ESBL)-producing and extensively drug-resistant (XDR) isolates from the community resulting in infection requiring hospitalization, especially in individuals lacking risk factors. In the United States, exposure to ESBL-producing E. coli is typically nosocomial, whereas patients from developing countries often encounter ESBL-producing E. coli in the community through the consumption of contaminated food or water. Considering the rarity at which XDR E. coli isolates are encountered, there is also a scarcity of literature describing the successful treatment of ESBL-producing XDR E. coli. Here we present a case of an otherwise healthy 28-year-old female delicatessen worker infected with ESBL-producing and XDR E. coli without recent travel, antibiotic use, or healthcare contact, who required admission to the intensive care unit (ICU) with pyelonephritis and septic shock. Treatment with intravenous meropenem through a peripherally inserted central catheter (PICC) line at home was curative and follow up thereafter unremarkable. Given the patient's lack of obvious exposure to and risk factors for an ESBL-producing XDR E. coli infection and the specific lack of risk factors for severe pyelonephritis requiring hospitalization, this case represents a unique addition to the literature and is of value to clinicians by describing successful treatment.

Point-of-care ultrasound to evaluate volume status in severe hyponatremia.

A 51-year-old man was hospitalised for severe hyponatremia. Initial history and physical examination suggested hypovolemia, and he was treated with normal saline at 100 mL/hour. After several days, his hyponatremia failed to improve, and then worsened without resolution of presenting ataxia and fatigue. He had no new complaints including no cough or orthopnea. He had no jugular venous distention or oedema, and his lungs were clear to auscultation. Point-of-care ultrasound was used, revealing a distended inferior vena cava, pulmonary oedema and pleural effusion, suggesting hypervolemia. Based on ultrasound findings, we treated with 60 mg oral torsemide two times per day. Hyponatremia resolved without complication within 48 hours. In this case, physical examination failed to recognise volume status change from hypovolemic to hypervolemic, increasing hospitalisation and morbidity. The point-of-care ultrasound proved to be an accurate tool for proper volume evaluation, and may be used as an adjunct to physical examination for hyponatremic patients.
