64-1.09), respectively. The number of GTSs did not have a significant association with mortality. Similar results were observed for patients in the lobectomy cohort.
 
  Low surgical mortality was consistent, regardless of the number of GTSs in each hospital.

The genes involved in the biotransformation of estrogens and xenobiotics have allelic variants with modified enzymatic activities. We investigated the association of nine polymorphisms of some genes from the classical estrogen pathway with the risk of breast cancer and their role in the clinicopathological characteristics of poor clinical prognosis in a sample of Mexican women with BC.
  We included 150 controls and 150 cases matched by age.  https://www.selleckchem.com/products/go-6983.html  To analyze the selected polymorphisms, TaqMan assays and high-resolution melting (HRM) analysis were used.
 
  The polymorphisms of the genes ERα, CYP1A1, CYP1B1, COMT, MGMT, and XRCC1 were positively associated with the BC risk. We found negative associations between CYP1B1
  genotype and tumor size, and status of lymph node, estrogen receptor, triple negative, and survival.
 
  The polymorphisms included in this study are associated not only with the risk of BC, but also with some clinicopathological characteristics for poor prognosis of patients with breast cancer, highlighting the important role of CYP1B1 Leu432Val polymorphism.

  Infection with the SARS-COV2 virus (COVID-19) may be complicated by thrombotic diathesis. This complication often involves the pulmonary microcirculation. While macrovascular thrombotic complications of the lung may include pulmonary artery embolism, pulmonary artery thrombus in situ has also been hypothesized. Pulmonary vein thrombosis has not been described in this context.
 
  Herein, we provide a case of an otherwise healthy male who developed an ischemic stroke with left internal carotid thrombus. Further imaging revealed pulmonary emboli with propagation through the pulmonary veins into the left atrium. This left atrial thrombus provides a source of atypical "paradoxic arterial embolism".
 
  Thrombotic outcomes in the setting of severe COVID 19 pneumonia may include macrovascular venous thromboembolism, microvascular pulmonary vascular thrombosis and arterial thromboembolism. Pulmonary vein, herein described, provides further mechanistic pathway for potential arterial embolic phenomenon.

Less is known about how COVID-19 has impacted psychiatric emergency services (PES). This report compares visits to the Connecticut Department of Veterans Affairs psychiatric emergency room from March-August 2020 to the same period from three prior years (2017, 2018, 2019) to evaluate the impact of COVID-19 on patient volume and dispositions. Compared to prior years, there was a decline in visits in March-August 2020, particularly in April. This coincided with the peak of COVID-19 in the state. Rates of hospitalizations remained consistent, while rates of referrals to residential programs decreased. The decline in visits likely indicates that many veterans postponed necessary mental health and substance use treatment. This delay could have significant clinical ramifications for veterans and may lead to an eventual surge in demand for emergency mental health care.The black truffle (Tuber melanosporum Vittad.) and the summer truffle (Tuber aestivum Vittad.) are two of the most appreciated edible fungi worldwide. The natural distributions of both species partially overlap. However, the interspecific interactions between these truffles and how irrigation and mulching techniques impact the dynamics between them are still unknown. Here, an experimental truffle plantation with Quercus ilex was established in Maials (Catalonia, Spain), combining three soil mulch treatments (white mulch, black mulch and bare soil as a control) and two irrigation regimes (irrigated and non-irrigated as a control) to investigate truffle mycelial dynamics in soil when both truffle species co-occur. The development of truffle mycelium in two different seasons (spring and autumn) in two consecutive years (2017 and 2018) was quantified using qPCR. Truffle mycelia of both species showed greatest development under white mulch. When mycelia of both truffle species co-occurred in soil, irrigation combined with white mulch resulted in greater quantities of T. melanosporum mycelial biomass, whereas the control irrigation treatment favoured the development of T. aestivum. Mulch treatments were also advantageous for seedling growth, which was expressed as root collar diameter and its increment during the study period. Significant relationships between root collar diameter and root growth and the amount of mycelial biomass in the soil were observed for both truffle species. Our results indicate the potential advantages of using white mulch to support irrigation in truffle plantations located in areas with dry Mediterranean climatic conditions to promote the development of Tuber mycelium.Background Hospital pharmacy audit and feedback of 'do not use' medication abbreviations improves patient safety. For audit and feedback systems to be effective, the data captured must be of high quality such that end-users trust the information to guide practice change. The quality of data captured during monthly standardized pharmacy 'do not use' abbreviation audits is currently unknown. Objective We aimed to assess pharmacy 'do not use' abbreviation audit data quality. Method Primary audit data quality was assessed by examining a random sample of handwritten medication prescriptions for the presence and type of 'do not use' abbreviations. This data was compared with the pharmacy monthly audit data to determine data capture agreement and consistency over time. Results There were 1132 prescriptions from July, October, and December 2019 included. Data capture agreement between the pharmacy audit and the secondary assessment using Cohen's Kappa ranged from 0.53 to 0.63. The primary audit under-reported 'do not use' abbreviation rates, however this did not vary over time (χ2 = 1.
