Filter clotting is a major issue in continuous kidney replacement therapy (CKRT) that interrupts treatment, reduces delivered effluent dose, and increases cost of care. While a number of variables are involved in filter life, treatment modality is an understudied factor. We hypothesized that filters in pre-filter continuous venovenous hemofiltration (CVVH) would have shorter lifespans than in continuous venovenous hemodialysis (CVVHD). This was a single center, pragmatic, unblinded, quasi-randomized cluster trial conducted in critically ill adult patients with severe acute kidney injury (AKI) at the University of Iowa Hospitals and Clinics (UIHC) between March 2020 and December 2020. Patients were quasi-randomized by time block to receive pre-filter CVVH (convection) or CVVHD (diffusion). The primary outcome was filter life, and secondary outcomes were number of filters used, number of filters reaching 72 hours, and in-hospital mortality. In the intention-to-treat analysis, filter life in pre-filter CVVH was 79% of that observed in CVVHD (mean ratio 0.79, 95% CI 0.65-0.97, p = 0.02). Median filter life (with interquartile range) in pre-filter CVVH was 21.8 (11.4-45.3) and was 26.6 (13.0-63.5) for CVVHD. In addition, 11.8% of filters in pre-filter CVVH were active for >72 hours, versus 21.2% in the CVVHD group. Finally, filter clotting accounted for the loss of 26.7% of filters in the CVVH group compared to 17.5% in the CVVHD group. There were no differences in overall numbers of filters used or mortality between groups. Among critically patients with severe AKI requiring CKRT, use of pre-filter CVVH resulted in significantly shorter filter life compared to CVVHD. ClinicalTrials.gov, NCT04762524.

We present a 61-year-old Caucasian woman with endometroid carcinoma as well as a poorly differentiated adenocarcinoma who developed severe hypercalcaemia in the setting of an elevated intact parathyroid hormone. The patient was hospitalised twice for her condition. During her first hospitalisation, she was diagnosed with an endometroid carcinoma and hypercalcaemia. With medical management, she had a normal calcium level on discharge. She presented 3 weeks later with hypercalcaemia and encephalopathy. This time her hypercalcaemia was refractory to medical management, and required continuous renal replacement therapy (CRRT) to normalise her serum calcium. Lung biopsy revealed a poorly differentiated adenocarcinoma, suspicious for pancreatic primary. Due to her poor prognosis, rapid elevation of calcium with each attempt to discontinue CRRT, and the poor options for treatment of her cancers, she elected to pursue hospice care.

We report the case of a previously healthy man who presented with subacute dyspnoea after a long drive. He developed hypoxic respiratory failure, thought secondary to a massive pulmonary embolism and was treated with tissue plasminogen activator but died in the hospital despite aggressive medical measures. Autopsy revealed pulmonary tumour thrombotic microangiopathy (PTTM) from papillary renal cell carcinoma. PTTM is a rare clinicopathological syndrome that clinically results in symptoms of dyspnoea and right heart failure. Pathologically, a localised paraneoplastic process evolves from tumour microemboli in the pulmonary arterioles, resulting in fibrocellular proliferation and narrowing of the vessels, causing subacute right heart failure. To our knowledge, this is the first case of PTTM due to papillary renal cell carcinoma.

This dissertation re-establishes Paris, through its symbiotic relationship with the royal court, as a major centre for the production, performance and transmission of sacred and secular polyphonic repertoires at the turn ofthe fifteenth century. It shows that the French royal court anchored in Paris represented an important point of reference for all musicians, including the composers Jean Vaillant, Jacquet de Noyon, J. Solage, Jean Carmen and Jean Cesaris, and paves the way for new interpretations ofthe surviving musical repertoires. Chapter 1 underlines the importance ofParis to the careers of musicians active in royal courtly circles as an ideal location for the development of networks ofsocial and professional acquaintances for musicians. The clerical nature of singers' and organists' training set them on a par with those clerks employed in the royal court and the governmental bodies based on the lIe-de-la-Cite, who patronized polyphonic music in the capital's ecclesiastical institutions. Chapter 2 focuses on the Sainte-Chapelle ofParis as a centre of musical excellence. The Sainte-Chapelle was linked to the court, through accumulation ofoffices and frequent movements ofpersonnel, and to the citY, through accumulation ofbenefices at Parisian churches and chapels. Sainte-Chapelle musicians performed during processions through Paris, at royal courtly events contexts or on more private occasions patronized by clerks active in royal service. Chapter 3 highlights points ofcontact between musicians active in the University quarters and those active at the royal court, setting the scene for the transmission and discussion of courtly repertoires in the University. Information concerning the patronage of polyphony at the Dormans College by clerks active in royal service supports the theory of shared musical repertoires at court and in the University.
