A 36-year-old man who presented multiple times with fever, headache, alteration of mental status, and focal neurological deficits. MRI revealed extensive white matter lesions that were partially reversed between episodes. Workup revealed persistently low complement factor C3, low factor B, and absent alternative complement pathway activity. Biopsy revealed neutrophilic vasculitis. Genetic testing revealed a homozygous mutation in complement factor I (CFI), that was felt to be pathogenic. CFI regulates complement mediated inflammation, and deficiency in this factor leads to unchecked alternative pathway activity and decrease in C3 and factor B through consumption. The patient has remained stable since starting IL-1β inhibition. Complement factor I is a rare disorder that should be considered in patients with atypical relapsing neurological disease associated with neutrophilic pleocytosis.

'The Index of Digital Humanities Conferences' is a database of conference metadata relevant to the digital humanities community dating back to the 1960s. It includes details about hundreds of conferences, and for a subset of them, details about work presented at those events. Weingart, Eichmann-Kalwara, Lincoln, and research assistants collected information by hand or with machine assistance from paper programs, listserv announcements, published proceedings, PDF programs, and conference websites. Data are in CSV tables with a data dictionary describing how they can be linked together, for use by digital humanists and bibliometricians to study the history of the digital humanities community.

COVID-19 has become a pandemic since its emergence in Wuhan, China. The disease process was initially defined by presence of respiratory symptoms; however, it is now well studied and shown in evidence that this is a multisystem process. Involvement of gastrointestinal (GI) system has been identified, and GI symptoms can be the only presenting symptoms in some patients. Hence, it is important to identify and understand the GI symptoms associated with COVID-19 for appropriate care of patient. We conducted a systematic review and metaanalysis to identify the GI symptoms of COVID-19 and identify association of diarrhea with severity of COVID-19. We performed extensive search of Medline and Embase from December 2019 to May 2020 to identify articles reporting GI symptoms in COVID-19 patients. The primary outcome was prevalence of GI symptoms in COVID-19 patients, and secondary outcome was the association of diarrhea with disease severity. A total of 38 studies with 8407 patients were included. Of the total patients, 15.47% patients had at least one GI symptom. The pooled prevalence of nausea/vomiting was 7.53% and diarrhea was 11.52%. On metaanalysis, patients with diarrhea as one of the presenting symptoms were more likely to have severe disease (OR 1.63, 95% CI: 1.11–3.38, p = 0.01). Our systematic review and metaanalysis demonstrated that GI symptoms are common in COVID-19. Presence of diarrhea as a presenting symptom is associated with increased disease severity and likely worse prognosis. Early recognition of patients is needed for prompt management of this at-risk population.

INTRODUCTION: Since its emergence in Wuhan, China in late 2019, COVID-19 has become a global pandemic Initially defined predominantly by respiratory symptoms, it is now well understood that COVID-19 affects multiple systems Gastrointestinal (GI) symptoms have been identified in these patients and in some patients, these are the only presenting symptoms Therefore, it is vital that we identify and understand the GI symptoms associated for prompt diagnosis and management We [200] Figure 1 Forest plot of studies with odd's ratio (OR 1 63, 95% CI: 1 11-2 38, P = 0 01) conducted a systematic review and meta-analysis to identify the GI symptoms of COVID-19 and its association with disease severity METHODS: We searched Medline and Embase from December 2019 to May 2020 to identify articles reporting GI symptoms in COVID-19 patients The primary outcome was prevalence of GI symptoms in COVID-19 patients, and secondary outcome was the association of GI symptoms with disease severity RESULTS: A total of 38 studies with 8,407 patients were included Of the total patients, 15 47% patients had at least one GI symptom The pooled prevalence of nausea/vomiting was 7 53% and diarrhea was 11 52% (Table 1) On meta-analysis, patients with diarrhea as one of the presenting symptoms were more likely to have severe disease (OR 1 63, 95% CI: 1 11-3 38, P = 0 01) as shown in Figure 1 CONCLUSION: Our systematic review and meta-analysis demonstrated that GI symptoms are common in COVID-19 patients with diarrhea and nausea/vomiting being the predominant symptoms Presence of diarrhea as a presenting symptom is associated with increased disease severity and likely worse prognosis Patients with diarrhea likely harbor increased viral load, which can potentially lead to an increased systemic response to the virus and associated respiratory complications from it Early recognition of patients is needed for prompt management of this at-risk population

Aux Etats-Unis comme ailleurs, l’introduction et l’evolution ininterrompue des technologies numeriques dans la recherche, l’edition et l’enseignement de l’histoire de l’art depuis les annees 1980 ont modifie la discipline en profondeur. L’abandon des diapositives au profit d’images numerisees est communement designe comme l’un des premiers signes visibles de ce tournant numerique qui interroge et agite la discipline aujourd’hui. En effet, les outils numeriques ont engendre un remodelage de to...

Computational analysis of the potential historical professional networks inferred from surviving print impressions offers novel insight into the evolution of early modern artistic printmaking in Europe. This analysis traces a longue durée print production history that examines the changing ways in which different regional printmaking communities interacted between 1550 and 1750, highlighting the powerful impact of demographic forces and calling in to question narratives based on single key individuals or the emergence of specific national schools.

This deposit contains materials for the Jekyll-based static site for The Programming Historian. The Programming Historian publishes novice-friendly, peer-reviewed tutorials that help humanists learn a wide range of digital tools, techniques, and workflows to facilitate research and teaching. We are committed to fostering a diverse and inclusive community of editors, writers, and readers. At the time of deposit, The Programming Historians hosts 67 lessons. To date in 2017 we published 11 new lessons and retired 3 existing lessons. 28 lessons were translated into Spanish. This deposit provides a citation for the project as it stands in November 2017. It is not intended to replace the Programming Historian website. This deposit supersedes the 2016 deposit (see 'Previous versions' for more info).

In the United States, as elsewhere, the continuous application and evolution of digital technology in art history research, publishing and teaching since the 1980s have had a profound impact on the discipline. The disappearance of slides in favour of digital images is widely cited as one of the first visible signs of the digital revolution challenging and revolutionising the discipline today. Digital tools have indeed led to a reshaping of the entire art history infrastructure, and to a renew...

According to most modern scholarship, it was during his time in Italy that Honthorst earned the nickname “Gherardo delle Notti,” or “Gerrit of the nights,” because of his talent for rendering dramatic nighttime images… The attentive reader will notice, however, that none of these texts credit the nickname to a contemporary source. When did Honthorst actually earn this name? An investigation of archival sources suggests that “Gherardo delle Notti” may not be nearly as contemporary as has been assumed.
