RESUMO

BACKGROUND: Physicians often obtain a routine renal bladder ultrasound (RBUS) for young children with a first febrile urinary tract infection (UTI). However, few children are diagnosed with serious anatomic anomalies, and opportunity may exist to take a focused approach to ultrasonography. We aimed to identify characteristics of the child, prenatal ultrasound (PNUS), and illness that could be used to predict an abnormal RBUS and measure the impact of RBUS on management. METHODS: We conducted a single-center prospective cohort study of hospitalized children 0 to 24 months of age with a first febrile UTI from October 1, 2016, to December 23, 2018. Independent variables included characteristics of the child, PNUS, and illness. The primary outcome, abnormal RBUS, was defined through consensus of a multidisciplinary team on the severity of ultrasound findings important to identify during a first UTI. RESULTS: A total of 211 children were included; the median age was 1.0 month (interquartile range 0-2), and 55% were uncircumcised boys. All mothers had a PNUS with 10% being abnormal. Escherichia coli was the pathogen in 85% of UTIs, 20% (n = 39 of 197) had bacteremia, and 7% required intensive care. Abnormal RBUS was found in 36% (n = 76 of 211) of children; of these, 47% (n = 36 of 76) had moderately severe findings and 53% (n = 40 of 76) had severe findings. No significant difference in clinical characteristics was seen among children with and without an abnormal RBUS. One child had Foley catheter placement, and 33% received voiding cystourethrograms, 15% antibiotic prophylaxis, and 16% subspecialty referrals. CONCLUSIONS: No clinical predictors were identified to support a focused approach to RBUS examinations. Future studies should investigate the optimal timing for RBUS.

RESUMO

The primary aim of the Million Hearts initiative is to prevent 1 million cardiovascular events over 5 years. Concordant with the Million Hearts' focus on achieving more than 70% performance in the "ABCS" of aspirin for those at risk, blood pressure control, cholesterol management, and smoking cessation, we outline the cardiovascular events that would be prevented and a road map to achieve more than 70% participation in cardiac rehabilitation (CR)/secondary prevention programs by the year 2022. Cardiac rehabilitation is a class Ia recommendation of the American Heart Association and the American College of Cardiology after myocardial infarction or coronary revascularization, promotes the ABCS along with lifestyle counseling and exercise, and is associated with decreased total mortality, cardiac mortality, and rehospitalizations. However, current participation rates for CR in the United States generally range from only 20% to 30%. This road map focuses on interventions, such as electronic medical record-based prompts and staffing liaisons that increase referrals of appropriate patients to CR, increase enrollment of appropriate individuals into CR, and increase adherence to longer-term CR. We also calculate that increasing CR participation from 20% to 70% would save 25,000 lives and prevent 180,000 hospitalizations annually in the United States.

RESUMO

PURPOSE: Most studies on pathogenesis of tumor metastasis focus on cell adhesion and migration. Little is understood of how cell cycle pathways critically affect cell fate of metastatic cells and their sensitivity to anticancer drugs. In this study, we investigated cell cycle checkpoint progression and regulation in the presence of cisplatin in metastatic hepatocellular carcinoma (HCC) cells. EXPERIMENTAL DESIGN: Cisplatin-mediated cell cycle progression and Polo-like kinase 1 (Plk1)-Cdc25A pathway were compared between metastatic and nonmetastatic HCC cells by flow cytometry, Western blots, and reverse transcription-PCR. Cdc25A expression in clinical HCC samples was detected using immunohistochemistry and its association with clinical HCC metastasis was analyzed. RESULTS: Cisplatin induced degradation of Cdc25A in nonmetastatic HCC cells but not in metastatic HCC cells. Hence, metastatic HCC cells showed defective S-M cell cycle phase arrest and continued to enter mitosis. Tumor expression of Cdc25A was strongly associated with metastatic diseases in HCC patients, and elevated Cdc25A expression significantly correlated with HCC tumor-node-metastasis staging and venous invasion. Metastatic HCC cells did not show down-regulation of Plk1 that was normally induced by DNA damage. Blockage of Plk1 expression in metastatic HCC cells initiated Cdc25A degradation in response to DNA damage, suggesting that Plk1 could be an upstream regulator of Cdc25A. Deregulated Plk1-Cdc25A pathway in metastatic HCC cells and primary tumors did not result in drug-induced mitotic catastrophe but rather in accumulation of damaged DNA due to checkpoint adaptation. CONCLUSIONS: Metastatic HCC cells showed a defective S-M checkpoint following cisplatin treatment and potential aberrant checkpoint adaptation, which might result from deregulation of Plk1-Cdc25A pathway.

RESUMO

Vasovagal syncope is a condition better known as neurocardiogenic or neurally mediated syncope. Dysautonomic syncope is the irregular neuroautonomic response during the body's attempt to maintain homeostasis. Both types of syncope are associated with orthostatic hypotension and are nonlethal. The underlying pathophysiology manifests the vast symptoms suffered by the individual. Research continues to develop new markers to improve diagnostic testing and therapies for treatment. Advanced practice nurses now have a new tool with Head-Up Tilt Training Programs to offer the patients who suffer from frequent and refractory neurocardiogenic and dysautonomic syncope.
