AIMS: There is considerable controversy regarding optimal management of patients with paraesophageal hiatus hernia (pHH). This survey aims at identifying recommended strategies for work-up, surgical therapy, and postoperative follow-up using Delphi methodology.METHODS: We conducted a 2-round, 33-question, web-based Delphi survey on perioperative management (preoperative work-up, surgical procedure

OBJECTIVE: To study the effect of methotrexate on male fertility and subsequent effects on their children, for which data are scarce and contradictory.DESIGN: Nationwide multiregister cohort study.SETTING: Not applicable.SUBJECT(S): All children born alive in Sweden between 2006 and 2014 and their fathers. Three cohorts were defined: children to fathers with periconceptional methotrexate exposure

The role of multiple groups of primary biological aerosol particles (PBAPs) as ice nucleating particles (INPs), and of ice formation processes such as time-dependent freezing of various INPs, and various secondary ice production(SIP) mechanisms in overall ice concentration has been evaluated in a range of cloud systems by simulating them numerically with the state-of-the-art ‘Aerosol-Cloud’ (AC) m

The α decay of the neutron-deficient 190At isotope was observed following the 103Rh(90Zr,3n)190At reaction at Argonne National Laboratory. The reaction products were separated from the beam using the Argonne Gas-Filled Analyzer and implanted into a double-sided Si strip detector. The spatial and temporal correlations between implanted nuclei and subsequent α decays towards the known daughter isoto

Non-metallic inclusions offer one of the most effective routes for improving the machinability of steels. However, the wear-reducing mechanisms activated by such inclusions are not fully understood. The interactions are notoriously difficult to predict due to the wide variety of steel grades, cutting conditions, and tool materials employed in industry. The interaction between PVD (Ti,Al)N coated c

The building sector is the biggest energy user in the European Union (EU) and therefore, has an important role to play in meeting the energy and climate goals ofEU. In Sweden, more than 80% of the two million detached houses are more than 35 years of age. Energy efficiency renovation of those old houses can reduce primary energy use by 65% to 90%. However, the current low rate of energy renovation

BackgroundUniversity students experience a distinct working environment in the context of completing their studies. In line with existing research into the connection between workplace environment and stress, it is rational to believe that such study environments can affect the level of stress that students experience. However, few instruments have been developed for measuring this.ObjectiveThe ai
