Multicenter StudyPrognostic value of glomerular filtration rate estimation equations in acute heart failure with preserved versus reduced ejection fraction.
Renal function is an important prognostic factor in heart failure. The aim of this study was to compare the predictive value of estimated renal function calculated by the Chronic Kidney Disease-Epidemiology Collaboration equation (CKD-EPI) and the abbreviated Modification of Diet in Renal Disease (MDRD-4) equation for long-term all-cause mortality in patients admitted for acute decompensated heart failure (ADHF) with both preserved ejection fraction (HF-PEF) and reduced ejection fraction (HF-REF). ⋯ In this clinical cohort of ADHF patients, eGFR as calculated by both the CKD-EPI and the MDRD-4 formulas offered similar prognostic information, irrespective of ejection fraction status, but in HF-PEF patients specifically, the CKD-EPI formula seems to improve clinical risk stratification as compared with MDRD-4.

Reasons for non-adherence to nicotine patch therapy during the first month of a quit attempt.
Prior research has shown that the transdermal nicotine patch is a safe and effective aid to smoking cessation, but adherence to the directed use of the nicotine patch is often low. Few studies have examined participant-reported reasons for non-adherence to nicotine patch therapy during a quit attempt. ⋯ Participant- reported barriers to adherence of nicotine patch therapy can be mitigated with advice from healthcare providers. Some examples of advice to patients could include carrying an extra patch, using community resources to obtain free or reduced cost nicotine patches, reviewing the effectiveness of nicotine replacement, and explaining side effects associated with the use of the nicotine patch.

Comparative Study Observational StudyComparison of community-onset healthcare-associated and hospital-acquired urinary infections caused by extended-spectrum beta-lactamase-producing Escherichia coli and antimicrobial activities.
We aimed to compare community-onset healthcare-associated (CO-HCA) and hospital-acquired (HA) urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in terms of epidemiology, clinical outcomes and antimicrobial activities. ⋯ ESBL-producing E. coli should be taken into consideration in patients with a CO HCA UTI, not only in hospital settings but also in outpatient settings. We suggest ertapenem as a first-line empirical treatment for patients with an upper UTI and fosfomycin and nitrofurantoin for those with a lower UTI when ESBL-producing E. coli is suspected.

ReviewStroke prevention with rivaroxaban in higher-risk populations with atrial fibrillation.
Atrial fibrillation (AF), the most common cardiac arrhythmia, is a major risk factor for stroke. Rivaroxaban, an oral factor Xa inhibitor, is approved for the prevention of stroke in patients with non-valvular AF. In the pivotal phase III trial ROCKET AF, rivaroxaban demonstrated non-inferiority compared with warfarin for reducing the risk of stroke or systemic embolism (SE) in patients with AF (intention-to-treat analysis), without an increased risk of major bleeding. Superior efficacy vs. warfarin was achieved while patients were on study medication. Other direct oral factor Xa inhibitors have completed phase III clinical trials in this indication. Compared with warfarin, apixaban (in the ARISTOTLE trial) and edoxaban (in the ENGAGE-AF trial) were shown to be superior or non-inferior, respectively, for reduction in stroke or SE risk in patients with AF. Baseline stroke risk, as indicated by CHADS2 scores, was lower in patients in the ARISTOTLE and ENGAGE-AF trials than in ROCKET AF. ⋯ These subgroup analyses demonstrate that the treatment effect for rivaroxaban vs. warfarin is broadly consistent across a wide range of patient groups, with respect to both efficacy and safety.

ReviewSubclinical hypothyroidism: a historical view and shifting prevalence.
Accurate diagnosis and treatment of subclinical hypothyroidism (SCH) is challenging in clinical practice because of differing upper limits of normal (ULN) for thyroid-stimulating hormone (TSH). This review summarises the various definitions of SCH and their impact on reported SCH prevalence. ⋯ Given the variable definition of SCH based on an inconsistent ULN for TSH, it is currently difficult to ascertain the true prevalence of SCH and to correctly label and treat patients with SCH; use of age-adjusted definitions may be considered when assessing prevalence. A diagnosis of SCH does not necessarily merit treatment, especially if TSH elevations are transient (i.e. not persistent for > 3-6 months) and the patient lacks other risk factors for developing overt hypothyroidism.
