Fine needle aspiration cytology of hepatic metastases of neuroendocrine tumors: A 20‐year retrospective, single institutional study

Background Fine needle aspiration (FNA) is considered an excellent technique for documenting metastatic neuroendocrine tumors (NETs). This study aims to evaluate the accuracy of FNA in diagnosing metastatic NETs to the liver and determining the grade and origin of these metastases. Methods Our laboratory information system was searched from 1997 to 2016 to identify all cases of metastatic NETs to the liver that were sampled by FNA. The cytopathology and surgical pathology reports as well as the patients' electronic medical records were reviewed. The cytohistologic type and grade of the metastatic NETs, as well as the site of the patient's primary were recorded. Results High‐grade NETs, including small cell and poorly differentiated neuroendocrine carcinomas, constituted 62% (167/271) of the cases, while low‐grade NETs, including well differentiated NET (grade1 and grade 2), pheochromocytomas, paragangliomas, and carcinoid tumors of lung, constituted 38% (104/271) of cases. The most common diagnosis was metastatic small cell carcinoma accounting for 45% (122/271) of cases. The most common primary sites were lung (44%; 119/271) followed by pancreas (19%; 51/271). The FNA diagnosis was confirmed by histopathology in 121 cases that had a concurrent biopsies or resection specimens. Conclusions FNA is an accurate method for diagnosing metastatic NETs to the liver. There were significantly more high‐grade (62%) than low‐grade (38%) metastatic NETs to the liver. In our practice, lung (44%) and pancreas (19%) were the most common primary sites of metastatic NETs involving the liver. In 16% of the cases, a primary site could not be established

Measuring entanglement in condensed matter systems

We show how entanglement may be quantified in spin and cold atom many-body systems using standard experimental techniques only. The scheme requires no assumptions on the state in the laboratory and a lower bound to the entanglement can be read off directly from the scattering cross section of Neutrons deflected from solid state samples or the time-of-flight distribution of cold atoms in optical lattices, respectively. This removes a major obstacle which so far has prevented the direct and quantitative experimental study of genuine quantum correlations in many-body systems: The need for a full characterization of the state to quantify the entanglement contained in it. Instead, the scheme presented here relies solely on global measurements that are routinely performed and is versatile enough to accommodate systems and measurements different from the ones we exemplify in this work.Comment: 6 pages, 2 figure

Prevalence and predictors of yogic breathing and meditation use - A nationally representative survey of US adult yoga practitioners.

Introduction Yoga practice in common usage is often confined to the physical aspects of the comprehensive practice. The purpose of this study was to examine the use of two additional aspects of yoga as part of yoga practice, i.e. yogic breathing and meditation (YoBaM). Prevalence and predictors of YoBaM use among yoga practitioners in the US general population were analyzed. Method Cross-sectional data from the 2012 and 2017 National Health Interview Survey (NHIS) (N = 61,267) was used. 12-month prevalence of yoga use and YoBaM use among yoga practitioners were analyzed descriptively for the two cohorts respectively. Logistic regression analyses were used to analyze sociodemographic and health-related predictors of YoBaM use among yoga practitioners. Results 12-month prevalence of yoga use and YoBaM use were 8.9 % and 4.8 % respectively in 2012. In 2017, 13.3 % had practiced yoga in the past 12 months and 7.0 % had used YoBaM. Yoga practitioners aged between 50 and 64 compared to being 29 or younger, females, Hispanics and those experiencing mild to severe forms of psychological distress were more likely to use YoBaM as part of their yoga practice. Yoga practitioners living in the Midwest or in a relationship were less likely to use YoBaM. Conclusion In recent years, the number of yoga practitioners in the US general population has considerably increased and YoBaM use is common among yoga practitioners. YoBaM use seems to be associated with age, gender, ethnicity, region, marital status and psychological distress dimensions
