Strontium titanate (SrTiO3 or STO) is important for oxide-based electronics as it serves as a standard substrate for a wide range of high-temperature superconducting cuprates, colossal magnetoresistive manganites, and multiferroics. Moreover, in its heterostructures with different materials, STO exhibits a broad spectrum of important physics such as superconductivity, magnetism, the quantum Hall effect, giant thermoelectric effect, and colossal ionic conductivity, most of which emerge in a two-dimensional (2D) electron gas (2DEG) formed at an STO interface. However, little is known about its counterpart system, a 2D hole gas (2DHG) at the STO interface. Here, a simple way of realizing a 2DHG with an ultrahigh mobility of 24 000 cm2 V-1 s-1 is demonstrated using an interface between STO and a thin amorphous FeOy layer, made by depositing a sub-nanometer-thick Fe layer on an STO substrate at room temperature. This mobility is the highest among those reported for holes in oxides. The carrier type can be switched from p-type (2DHG) to n-type (2DEG) by controlling the Fe thickness. This unprecedented method of forming a 2DHG at an STO interface provides a pathway to unexplored hole-related physics in this system and enables extremely low-cost and high-speed oxide electronics. © 2020 WILEY-VCH Verlag GmbH & Co.

OBJECTIVES To investigate pre-existing comorbidities in HF patients versus matched controls and to assess their impact on mortality. METHODS We included all first-time in-hospital and outpatient diagnoses of HF from 1995 to 2017, and comorbidities antedating the HF-diagnosis in the Danish nationwide registries. HF patients were matched with up to five controls. One-year all-cause mortality rates and population attributable risk (PAR) were estimated for three separate age groups (≤50, 51-74 and >74 years). RESULTS Totally 280 002 patients with HF and 1 166 773 controls were included. Cardiovascular comorbidities, for example, cerebrovascular disease and ischaemic heart disease were more frequent in the oldest (17.9% and 29.7% in HF vs. 9.8% and 10.7% in controls) compared to the youngest age group (3.9% and 15.2% in HF vs. 0.7% and 0.9% in controls). Amongst patients with HF, 1-year mortality rates (per 100 person-years) were highest amongst those with >1 noncardiovascular comorbidity ≤50 years (10.4; 9.64-11.3), 51-74 years (23.3; 22.9-23.7), >74 years (58.5; 57.9-59.0); hazard ratios 245.18 (141.45-424.76), 45.85 (42.77-49.15) and 24.5 (23.64-25.68) for those ≤50, 51-74 and >74 years, respectively. For HF patients ≤50 years, PAR was greatest for hypertension (17.8%), cancer (14.1%) and alcohol abuse (8.5%). For those aged >74 years, PAR was greatest for hypertension (23.6%), cerebrovascular disease (6.2%) and cancer (7.2%). CONCLUSIONS Heart failure patients had a higher burden of pre-existing comorbidities, compared to controls, which adversely impacted prognosis, especially in the young. © 2020 The Association for the Publication of the Journal of Internal Medicine.Two novel HLA-C alleles, HLA-C*070292 and HLA-C*07828, were identified. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.Repetitive negative thought plays an important role in the maintenance of mental health problems following bereavement. To date, bereavement researchers have primarily focused on rumination (i.e., repetitive thought about negative events and/or negative emotions), yet the interest in worry (i.e., repetitive thought about uncertain future events) is increasing. Both cognitive processes potentially lead to poorer adaptation to bereavement by contributing to loss-related avoidance and behavioural avoidance of activities. The current study aims to establish the differential associations of rumination and worry with symptoms of depression and prolonged grief and clarify if avoidance processes mediate the associations of rumination and worry with symptom levels. Four hundred seventy-four recently bereaved adults (82% female) filled out questionnaires assessing rumination, worry, loss-related and behavioural avoidance, and depression and prolonged grief symptoms. Rumination and worry were both uniquely associated with depression and prolonged grief symptoms. Compared with worry, rumination related more strongly to prolonged grief symptoms, whereas correlations of both cognitive styles with depression symptoms did not differ. Loss-related avoidance and behavioural avoidance partially mediated the associations of rumination and worry with prolonged grief symptoms. Behavioural avoidance partially mediated the associations of rumination and worry with depression symptoms.  https://www.selleckchem.com/products/bismuth-subnitrate.html  Findings suggest that exposure and behavioural activation may be effective interventions to reduce repetitive thinking and psychopathology after bereavement. © 2020 The Authors. Clinical Psychology & Psychotherapy published by John Wiley & Sons Ltd.Ureteric injury during radical hysterectomies for cervical cancer is a well-known complication requiring some form of intervention to redress the damage. The incidence is reported at approximately 2%. Direct ureteric injuries may be recognised and repaired at surgery, but if not, generally present within a week of surgery. Indirect injuries, consider due to infection combined with an element of ureteric devascularisation tend to present later. This article is protected by copyright.

Instead, a better understanding of how PTSD symptoms occur and vary over time within an individual requires exploring the idiographic network structure of PTSD. To do so, the present study used an intensive repeated-measures design to estimate intraindividual networks of PTSD symptoms on a person-by-person basis. Participants were 20 individuals who met criteria for PTSD and completed daily surveys assessing PTSD symptoms; surveys were completed four times per day for approximately 30 days. Employing a recently validated method provided by Fisher, Reeves, Lawyer, Medaglia, and Rubel (2017), we used these data to estimate a contemporaneous and temporal network of PTSD symptoms for individuals on a person-by-person basis. We then calculated centrality metrics to determine the relative importance of each symptom in each idiographic network.
