Deriving session and union types for objects

Guaranteeing that the parties of a network application respect a given protocol is a crucial issue. Session types offer a method for abstracting and validating structured communication sequences (sessions). Object-oriented programming is an established paradigm for large scale applications. Union types, which behave as the least common supertypes of a set of classes, allow the implementation of unrelated classes with similar interfaces without additional programming. We have previously developed an integration of the features above into a class-based core language for building network applications, and this successfully amalgamated sessions and methods so that data can be exchanged flexibly according to communication protocols (session types). The first aim of the work reported in this paper is to provide a full proof of the type safety property for that core language by renewing syntax, typing and semantics. In this way, static typechecking guarantees that after a session has started, computation cannot get stuck on a communication deadlock. The second aim is to define a constraint-based type system that reconstructs the appropriate session types of session declarations instead of assuming that session types are explicitly given by the programmer. Such an algorithm can save programming work, and automatically presents an abstract view of the communications of the session

Outpatient satisfaction during pharmacotherapy followup

This study aimed to investigate the satisfaction of patients with uncontrolled hypertension referred for pharmacotherapy followup. A cross-sectional study by semi-structured interview was used. The sample comprised patients undergoing pharmacotherapy followup, patients who had discontinued pharmacotherapy followup and patients who had not kept the appointments. A total of 80 (76.9 %) out of 104 patients registered were contacted. The majority of patients undergoing pharmacotherapy followup (91.1 %) were fully satisfied with the pharmacists' care given, their relationship with them (94.9 %), the manner in which their therapy was conducted (99.2 %) and the environment where it was carried out (85.3 %). The reasons for non-attendance were mostly forgetting the date, illness on the appointment day and other arrangements on the same day. Interestingly, all of these patients were completely satisfied with the pharmacists' care given. The satisfaction of patients with the pharmaceutical care is high among patients that have continuous followup, but a relevant proportion discontinued followup. Newer approaches to keep these patients under followup are necessary.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Population trends of the fan mussel Pinna nobilis from Portofino MPA (Ligurian Sea, Western Mediterranean Sea) before and after a mass mortality event and a catastrophic storm

Two Pinna nobilis populations thriving inside the borders of the Portofino Marine Protected Area (MPA) (Ligurian Sea, western Mediterranean Sea) were monitored before (2012) and after (September 2018) a dire mass mortality event that, since September 2016, spread through the whole Mediterranean Sea. In Portofino MPA, recorded mortality rates reached values of 91.29% and 43.94% in the two populations. The presence of a Haplosporidium protozoan parasite, considered to be the main cause of the mortality episodes, was confirmed from histological evidence: sporocysts and plasmodia were observed in all the tubules of the digestive glands of the collected specimens. Moreover, a catastrophic storm hit the Ligurian coasts at the end of October 2018, causing considerable damages both below and above the surface; a new survey conducted in November 2018 showed the complete annihilation of the two studied populations, as a probable combination of the continued parasite infections and the mechanical impacts caused by the storm. Finally, in June 2020 the sites were monitored again looking for traces of recovery, but no new specimens were recorded, indicating that P. nobilis became virtually absent from the MPA

Real-life comparison of Pirfenidone and Nintedanib in patients with Idiopathic Pulmonary Fibrosis: a 24-month assessment.

Background: Real-life data on the use of pirfenidone and nintedanib to treat patients with idiopathic pulmonary fibrosis (IPF) are still scarce. Methods: We compared the efficacy of either pirfenidone (n=78) or nintedanib (n=28) delivered over a 24-month period in patients with IPF, followed at two regional clinic centers in Italy, with a group of patients who refused the treatment (n=36), and who were considered to be controls. All patients completed regular visits at 1- to 3-month intervals, where primary [forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO)] and secondary outcomes (side effects, treatment compliance, and mortality) were recorded. Results: Over time, the decline in FVC and DLCO was significantly higher (p=0.0053 and p=0.037, respectively) in controls when compared with the combined treated group, with no significant difference between the two treated groups. Compared to patients with less advanced disease (GAP (Gender, Age, Physiology) stage I), those in GAP stages II and III showed a significantly higher decline in both FVC and DLCO irrespective of the drug taken. Side effects were similarly reported in patients receiving pirfenidone and nintedanib (5% and 7%, respectively), whereas mortality did not differ among the three groups. Conclusion: This real-life study demonstrated that both pirfenidone and nintedanib were equally effective in reducing the decline of FVC and DLCO versus non-treated patients after 24 months of treatment; however, patients with more advanced disease were likely to show a more rapid decline in respiratory function

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
