Data production in experimental sciences depends on localised experimental systems, but the epistemic properties of data transcend the contingencies of the processes that produce them. Philosophers often believe that experimental systems instantiate but do not produce the epistemic properties of data. In this paper, we argue that experimental systems' local functioning entails intrinsic capacities to produce the epistemic properties of data. We develop this idea by applying Derrida's model of arche-writing to study a case of theory-oriented experimental practice. Derrida's model relativises or dissolves the conceptual distinction between the moment of data production and a subsequent moment of data dissemination. It thus has consequences for understanding both data production (despite being intrinsically local, data production a priori generates transferrable and modellable information) and data dissemination (when modelling information, researchers needs to refer this information to the context of its production). We study a case of data production in a non-exploratory experimental system designed to test a pre-existing hypothesis in visual neuroscience. A case of theory-oriented experimental practice should allow us to identify the autonomous functioning of experimental systems in data production more clearly, insofar as it allows us to study the limits of pre-existing theory in the activities of these systems. We suggest that pre-existing concepts, hypotheses and theories condition the relevance but not the production of experimental data.
The aim of this meta-analysis of randomized controlled trials was to evaluate the effect of hydroxychloroquine on glucose control.

Randomized controlled trials examining the impact of hydroxychloroquine on glycemic markers were searched in PubMed, Web of Science, Scopus, and Google Scholar databases. Meta-analysis was performed using a random-effects model and sensitivity analysis through the leave-one-out method.

Meta-analysis revealed a significant reduction of fasting glucose (WMD - 8.05mg/dl; 95% CI - 11.17, - 4.93; I
 = 75%; p ˂0.0001), 2-h postprandial glucose (WMD - 15.52mg/dl; 95% CI - 20.61, - 10.42; I
 = 53%; p ˂0.00001), and glycated hemoglobin (HbA1c) values (WMD - 0.19%, 95% CI - 0.37, - 0.02; I
 = 94%; p = 0.03) after hydroxychloroquine treatment. Otherwise, meta-analysis showed no significant effect of hydroxychloroquine on insulin levels (WMD 16.52 μUI/ml; 95% CI - 16.35, 49.40; I
 = 90%; p = 0.32) and HOMA-β (WMD - 14.62; 95% CI - 45.84, 16.59; I
 = 0%; p = 0.36).

The present meta-analysis revealed that treatment with hydroxychloroquine improves glucose control through the reduction of fasting glucose, 2-h postprandial glucose, and HbA1c values. Given that the effect of hydroxychloroquine on beta-cell function is based only on two clinical trials, it is not possible to draw definitive conclusions.

While polycythaemia vera has well defined criteria, the diagnostic approach and management of other types of erythrocytosis are more challenging. The aim of study was to retrospectively analyse the aetiology and management of non-clonal erythrocytosis patients referred to a haematology outpatient clinic in an 8-year period using a 3-step algorithm. The first step was inclusion of patients with Hb > 185 g/L and/or Hct > 0.52 in men and Hb > 165 g/L and/or Hct > 0.48 in women on two visits ≥ two months apart, thus confirming true erythrocytosis. Secondly, polycythaemia vera was excluded and secondary causes of erythrocytosis (SE) identified. Thirdly, idiopathic erythrocytosis patients (IE) were referred to next-generation sequencing for possible genetic background evaluation. Of the 116 patients, 75 (65%) are men and 41 (35%) women, with non-clonal erythrocytosis 34/116 (29%) had SE, 15/116 (13%) IE and 67/116 (58%) stayed incompletely characterized (ICE). selleck chemicals llc Patients with SE were significantly older and had significantly higher Hb and Hct compared to patients with IE. Most frequently, SE was attributed to obstructive sleep apnoea and smoking. Phlebotomies were performed in 56, 53 and 40% of patients in the SE, IE, and ICE group, respectively. Approx. 70% of patients in each group received aspirin. Thrombotic events were registered in 12, 20 and 15% of SE, IE and ICE patients, respectively. Congenital erythrocytosis type 4 (ECYT4) was diagnosed in one patient. The study demonstrates real-life management of non-clonal erythrocytosis which could be optimized using a 3-step diagnostic algorithm.Coronavirus disease 2019 (COVID-19) has become a major public health problem worldwide since its outbreak in 2019. Currently, the spread of COVID-19 is far from over, and various complications have roused increasing awareness of the public, calling for novel techniques to aid at diagnosis and treatment. Based on the principle of molecular imaging, positron emission tomography (PET) is expected to offer pathophysiological alternations of COVID-19 in the molecular/cellular perspectives and facilitate the clinical management of patients. A number of PET-related cases and research have been reported on COVID-19 over the past one year. This article reviews the current studies of PET in the diagnosis and treatment of COVID-19, and discusses potential applications of PET in the development of management strategy for COVID-19 patients in the pandemic era.
Long-term effects on patient health-related quality of life (HRQoL) after direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) are unknown. We assessed the impact of DAA-mediated HCV clearance on HRQoL from DAA initiation to 1year after confirmed sustained virological response at 24weeks post-treatment (SVR24).

HRQoL was evaluated using the eight-item Short Form Health Survey (SF-8). Chronic HCV-infected patients were treated for 12weeks with sofosbuvir-based DAAs. SF-8 was administered at baseline, treatment cessation, SVR24, and 1-year post-SVR24.

A total of 109 chronic HCV-infected patients were enrolled. The average SF-8 scores were higher than the Japanese national standard values for bodily pain (BP) and mental health at baseline and for general health at 1-year post-SVR24. None of the SF-8 scores differed significantly between baseline and 1-year post-SVR24. Regarding age, sex, liver status, and treatment regimen, the SF-8 scores at 1-year post-SVR24 were affected by only age; individuals aged < 65years had significantly higher physical component score (PCS), physical functioning, role physical, and BP scores than older individuals.
