Complete Genome Sequence of Pseudomonas aeruginosa CMC-097, Isolated from a Ventilator-Associated Pneumonia Patient, Containing a Novel Carbapenem Resistance Class 1 Integron.

We report the complete genome of a clinical strain of Pseudomonas aeruginosa CMC-097, which was isolated from a ventilator-associated pneumonia patient with a chronic infection. Illumina sequence reads were assembled using Geneious to yield a 7,044,064-bp circular chromosome containing a carbapenem resistance integron, In2020.

Complete Genome Sequence of Pseudomonas aeruginosa CMC-115, a Clinical Strain from an Acute Ventilator-Associated Pneumonia Patient.

We report the complete genome of clinical strain Pseudomonas aeruginosa CMC-115, which was isolated from an acute ventilator-associated pneumonia patient. Illumina sequencing reads were assembled using Geneious to yield a 6,375,262-bp circular chromosome that exhibited an unusual ferrichrome receptor in the pyoverdine synthesis locus and the absence of type 3 secretion system genes.

Short Communication: Low Muscle Mass Is Associated with Osteoporosis in Older Adults Living with HIV.

Sarcopenia, age-related low muscle mass and function, is a well-established independent risk factor for bone fracture in the geriatric population but is understudied in older people living with HIV (PLWH). The objective of this cross-sectional study was to investigate in older PLWH the relationship between muscle mass and bone mineral density (BMD). Sedentary PLWH who were ≥50 years of age, receiving antiretroviral therapy, and enrolled in an exercise intervention trial were included. Established definitions for sarcopenia and osteopenia/osteoporosis were applied to muscle mass data and BMD collected by dual-energy X-ray absorptiometry before exercise training. Participants were 93% male and 33% Caucasian race with median age 61 years, and median CD4 lymphocytes 707 cells/µL. The majority (64%) were overweight and obese by body mass index. Appendicular skeletal muscle index (ASMI) correlated with BMD at the femoral neck (r = 0.49, p < .01), total hip (r = 0.54, p < .01), and lumbar spine (r = 0.48, p < .05). Low BMD at the femoral neck was present in 39% (26% osteopenia, 13% osteoporosis). ASMI was lower among those with low BMD compared with normal BMD (p = .02). Low muscle mass measured by ASMI is associated with low BMD in clinically stable older PLWH. Detailed body composition assessment may help guide lifestyle recommendations to prevent bone fractures in older PLWH.

Early clinical observations in prospectively followed patients with fungal meningitis related to contaminated epidural steroid injections.

UNLABELLED: Chinese translation BACKGROUND: Administration of epidural steroid injections (ESIs) with contaminated methylprednisolone resulted in an outbreak of fungal meningitis in many locations in the United States. OBJECTIVE: To characterize early clinical findings and initial response to treatment. DESIGN: Case series with standardized observation studied from 4 October to 31 October 2012. SETTING: An 800-bed hospital in Virginia. PATIENTS: 172 patients who presented to the hospital with exposure to contaminated ESI. INTERVENTION: Standardized approach to screening, case definition, treatment, and data collection. MEASUREMENTS: Clinical findings, cerebrospinal fluid (CSF) values, magnetic resonance imaging (MRI), serum and CSF voriconazole concentrations, and clinician assessment of response to therapy. RESULTS: Of 172 patients presenting to the hospital who had had ESI, 131 had lumbar puncture because of symptoms or signs consistent with central nervous system disease. Twenty-five (19%) had neutrophilic meningitis. All were started on voriconazole therapy alone. Three patients developed stroke during treatment. Ten patients had arachnoiditis, another had an epidural abscess, and 9 had urine retention. Fifteen continued to receive voriconazole, and 10 were switched to amphotericin B. Cerebrospinal fluid leukocyte counts began to decrease by day 13 of treatment. Findings on MRI included ventriculitis, leptomeningeal enhancement, infarction, hemorrhage, and arachnoiditis. Serum voriconazole levels varied, and CSF concentrations of voriconazole were approximately 50% those of serum. Exserohilum rostratum and Cladosporium species have been cultured. LIMITATIONS: This is an observational study of an evolving outbreak. Not all exposed patients presented for evaluation. Follow-up is too short to determine final outcomes. CONCLUSION: Meningitis after receipt of contaminated ESI has been diagnosed in many exposed patients presenting to 1 hospital. Most patients have improved on receipt of empirical voriconazole therapy. The full natural history and long-term sequelae of this infection are currently unknown. PRIMARY FUNDING SOURCE: None.
