Increased risk for premature mortality is well established for women and girls diagnosed with anorexia nervosa (AN), but less is known for other types of eating disorder (ED), and especially the mortality outcome for boys and men is under-studied. In this registry-based observational epidemiological study, we included all people appearing in the Danish Psychiatric Central Research Register with an eating disorder (ED) diagnosis in the time period from Jan 1,1970 to Dec 31, 2014 (N: 22,633). For each patient four controls without ED were selected, matched for age, sex and place of residence (N: 90486). In all 802 people with ED died over 255762.6 person-years of observation. Standardized mortality ratio (SMR) for all-cause mortality and suicide mortality was significantly increased for all ED-diagnoses in women. The SMRs for men were similar, but only reached significance for the diagnoses AN and unspecified ED. Mortality by natural causes and accidents was significantly increased in most ED-diagnoses in women. The unequal female-to-male ratio in this, and most other studies of ED-patients, suggests that boys and men with ED have unmet needs.

Ceftaroline (CPT) is a broad-spectrum agent with potent activity against methicillin-resistant Staphylococcus aureus (MRSA). The sequence type 5 (ST5) Chilean-Cordobés clone, associated with CPT nonsusceptibility, is dominant in Chile, a region with high rates of MRSA infections. Here, we assessed the in vitro activity of CPT against a collection of MRSA isolates collected between 1999 and 2018 from nine hospitals (n = 320) and community settings (n = 41) in Santiago, Chile, and evaluated performance across testing methodologies. We found that our hospital-associated isolates exhibited higher CPT MIC distributions (MIC50 and MIC90 of 2 mg/liter) than the community isolates (MIC50 and MIC90 of 0.5 mg/liter), a finding that was consistent across time and independent of the culture source. High proportions (64%) of isolates were CPT nonsusceptible despite the absence of CPT use in Chile. Across methodologies, the Etest underestimated the MIC relative to the gold standard broth microdilution (BMD) test (MIC50 and MIC90 of 1 and 1.5 mg/liter, respectively). There was low (∼51%) categorical agreement (CA) between Etest and BMD results across CLSI and EUCAST breakpoints. The recent revision of CLSI guidelines abolished \"very major error\" (VME) from the previous guidelines (81%), which perform similarly to the EUCAST guidelines. The level of concordance between CLSI and EUCAST for BMD testing and Etest was >95%. Disk diffusion performed poorly relative to BMD under CLSI (CA, 55%) and EUCAST (CA, 36%) guidelines. Comparison of EUCAST to CLSI for disk diffusion (with EUCAST used as the reference) showed low agreement (CA, 25%; VME, 70%). In summary, CPT-nonsusceptible MRSA are dominant in clinical settings in Chile. Our results provide data to support the reevaluation of CPT breakpoints and to improve agreement across methodologies and agencies.

To evaluate the association between appropriate antifungal treatment and mortality among patients with candidemia using different breakpoint definitions. In a retrospective study, we included all adults with candidemia in a tertiary center between 2009 and 2015. We defined three versions of appropriate (covering) antifungal treatment, according to Clinical and Laboratory Standards Institute (CLSI) 2008, CLSI 2012, and European Committee on Antimicrobial Susceptibility Testing (EUCAST) (2017 update) breakpoints. For empiric treatment, we evaluated the association with 30-day mortality. For definitive treatment, we evaluated the association with 90-day mortality among patients surviving the first week after candidemia onset. Adjusted odds ratios (OR) from a bivariate logistic regression with 95% confidence intervals are reported. We identified 302 patients with 308 separate candidemia episodes. The crude 30-day mortality was 55% (168/308). Resistance to anidulafungin increased from 3.5 to 51.6% and to fluconazole from 15.2 to 44.1%, when applying CLSI 2008 and EUCAST definitions, respectively. Appropriate empirical treatment was significantly associated with lower 30-day mortality using the CLSI 2008 definitions, adjusted OR 0.56 (0.33-0.96). The associations were similar, though not statistically significant for EUCAST, 0.58 (0.33-1.00), and CLSI 2012, OR 0.62 (0.37-1.04). Appropriate definitive treatment according to CLSI 2012 and EUCAST was independently associated with lower 90-day mortality, ORs 0.31 (0.13-0.75) and 0.44 (0.23-0.8), respectively. With CLSI 2008, the association was similar but not statistically significant, OR 0.4 (0.11-1.41), with few isolates classified as resistant. Considering the major shift in resistance prevalence when applying CLSI 2008, CLSI 2012, and EUCAST breakpoint definitions, no major differences were observed in their association with mortality.

Dalbavancin is a semisynthetic lipoglycopeptide approved for the treatment of acute skin and soft tissue infections due to Gram-positive microorganisms susceptible to this antimicrobial agent. The FDA (Food and Drug Administration) and the EUCAST (European Committee on Antimicrobial Susceptibility Testing) have established clinical breakpoints to interpret the results of the antibiogram (expressed as MIC [minimum inhibitory concentration]) with approved doses (1g intravenously [IV] followed by 0.5g IV at day 8 or 1.5g IV in a single dose). The EUCAST has also determined PK/PD (pharmacokinetic/pharmacodynamic) breakpoints -susceptible, ≤ 0.25mg/L; resistant, > 0.25mg/L-, established recommendations for in vitro susceptibility testing (addition of polysorbate-80 to the growth media) and subrogate values based on the vancomycin-susceptible category to interpret dalbavancin susceptibility in the absence of in vitro study of this antimicrobial.
