RESUMEN
BACKGROUND: Patients with end-stage renal disease (ESRD) undergoing chronic hemodialysis are at high mortality and cardiovascular risk. This study was aimed to assess whether the CHA2DS2-VASc score may be used for risk stratification of this population. METHODS: Included were patients undergoing chronic hemodialysis at Meir Medical Center. The CHA2DS2-VASc score was calculated for each patient at the initiation of hemodialysis. Patients were classified into 3 groups according to the CHA2DS2-VASc score: 0-3 (low), 4-5 (intermediate), and ≥6 (high). The primary endpoint was the composite of all-cause mortality, myocardial infarction, and stroke during the first year of hemodialysis. RESULTS: Of the 457 patients with ESRD, 181 (40%) had low, 193 (42%) intermediate, and 83 (18%) high CHA2DS2-VASc scores. During the first year of hemodialysis, 109 (23.8%) patients died, 17 (3.7%) had a stroke, and 28 (6.1%) had a myocardial infarction. Compared to patients in the low CHA2DS2-VASc score group, those in the intermediate and high score groups had higher risk for the composite endpoint (OR: 2.6, 95% CI: 1.6-4.2, p < 0.01 and OR: 4.2, 95% CI: 2.3-7.5, p < 0.01, respectively). Each 1-point increase in CHA2DS2-VASc score was associated with a 38% increased risk for the composite endpoint, a 19% increased risk for 1-year myocardial infarction, and a 29% increased risk for 1-year stroke. CONCLUSIONS: Patients with ESRD are at an extremely high mortality and cardiovascular risk within the first year of hemodialysis. The CHA2DS2-VASc score was strongly associated with adverse outcomes and may be used for risk stratification of these patients.

This retrospective study evaluates the incidence and risk factors of community-acquired urinary tract infections (CA-UTIs) linked to extended-spectrum beta-lactamase-producing Enterobacterales (ESBLPE). The study was conducted in a tertiary hospital in northern Israel and included children younger than 18 years with CA-UTIs due to Enterobacterales who were admitted to the emergency department, during the years 2017 to 2019. Among the 570 children, 9.8% had ESBLPE-associated CA-UTIs. This prevalence remained steady over the study period. ESBLPE exhibited substantial resistance to amoxicillin/clavulanic acid (62.5% vs 20.4%, P < .001, odds ratio [OR] = 6.5), trimethoprim/sulfamethoxazole (58.9% vs 18%, P < .001, OR = 6.6), ciprofloxacin (33.9% vs 3.1%, P < .001, OR = 15.9), piperacillin/tazobactam (26.8% vs 7%, P < .001, OR = 4.9), and gentamicin (21.4% vs 4.3%, P < .001, OR = 6.1), compared with non-ESBLPE. Risk factors for ESBLPE-associated UTIs included recent antibiotic treatment within the past 3 months (P = .003, OR = 3.5) and colonization with ESBLPE (P < .001, OR = 12.8). Given the variable incidence of ESBLPE, relying on local epidemiology for antibiotic selection pending culture results is crucial. The study finding of a low ESBLPE incidence, coupled with global concerns regarding carbapenem resistance, supports cautious use of broad-spectrum antibiotics in nonsevere cases.
RESUMEN
BACKGROUND: Non-polio enterovirus aseptic meningitis (NPE-AM) is a self-limiting illness that can mimic serious bacterial infection (SBI) in infants during their first months of life. OBJECTIVES: To compare the clinical features of febrile infants diagnosed with NPE-AM with those of infants who had SBI or non-bacterial infection (NBI). STUDY DESIGN: A systematic series of febrile infants < 3-months-old hospitalized between 2010 and 2019 with febrile illness in a tertiary hospital. Clinical and laboratory data were compared between the three groups. RESULTS: Overall 1278 infants were included; 207 (16.2%) had NPE-AM, 210 (16.4%) SBI and 861 (67.4%) NBI. The median age was 34 (IQR: 21.5-51.7) days. NPE-AM was documented in 25% of infants < 29 days and 9.9% of infants aged 29-90 days. Infants with NPE-AM or SBI had fever >39°C more frequently, 24.2% and 17.1% compared with 10% in infants with NBI (p < 0.001). Fever duration ≥ 2 days was reported in 3.4% of infants with NPE-AM vs 18.6% in SBI and 26.3% in NBI (p < 0001); rash occurred in 37.7% in NPE-AM compared to 4.6% in NBI and 5.7% in SBI (p < 0.001). The mean white blood count, C-reactive protein and absolute neutrophil count were significantly lower in infants with NPE-AM compared to infants with the SBI (p < 0.001) and similar to the means in infants with NBI (p = 0.848, 0.098 and 0.764 respectively). A high proportion of bloody tap 346/784 (53.1%) was detected. Infants with NPE-AM were more likely to be treated with antibiotics than infants with NBIs (88.9% vs 50.7%, p < 0.001), similarly to infants with SBIs (p = 0.571). CONCLUSIONS: The clinical presentation of infants with NPE-AM that could mimic bacterial infection and the high rate of bloody taps may lead to more hospital admissions and antibiotic prescriptions. Rapid molecular testing for detection of NPE may be of additional value in the evaluation of febrile infants.

It has been suggested that some of the adverse, long-term cardiovascular outcomes of smoking are mediated by impaired autonomic nervous system (ANS) activity. Yet, this association is currently inconclusive. Heart rate variability (HRV) and the deep breathing test (DBT) represent common quantitative markers of ANS activity due to their simplicity and reliability. This large cross-sectional study was designed to assess the effect of active smoking on ANS function as manifested by HRV or DBT abnormalities. Electrocardiograms were recorded at rest for 5 min and during forced metronomic breathing. HRV and DBT were calculated according to accepted standards. Participants were divided into two groups based on current smoking status. The study included 242 healthy volunteers (196 nonsmokers and 46 smokers). There were no significant differences in age, sex, and BMI between groups. Cumulative smoking exposure burden (CSEB) for the study group was 5.3 ± 1.3 pack-years. Comparative analysis of HRV and DBT parameters according to smoking status revealed no significant differences between groups. Significant (p < 0.05), yet weak or moderate correlations (r < 0.7) were found between CSEB and abnormal change in HRV parameters consistent with sympathetic overactivity and decreased parasympathetic tone. In conclusion, smoking for a relatively short period in healthy adults does not seem to lead to significant impairment in ANS function. Yet, the consequences of smoking seem to be amplified when cumulative exposure burden increases.
