Association of Physical Function and Survival in Older-Adult Renal Transplant Recipients

There is an increase in older-adult renal transplant recipients in United States. The objective of this study was to assess the association between physical function (PF) and patient survival in renal transplant recipients who are aged 65 years or older. Using United Network for Organ Sharing (UNOS) data from 2007 to 2016, renal transplant recipients aged 65 years or older were included. Multivariable Cox regression was used to assess associations between survival and functional status adjusted for age, sex, race, donor quality, diabetes, and dialysis vintage. The study identified 26,721 patients. Patient survival was significantly higher in recipients who needed no assistance and lowest in patients in need of total assistance (P < .0001). In deceased donor (DD) transplants, the relative risk for mortality was 2.06 (1.74-2.43) for total assistance and 1.17 (1.08-1.28) for moderate assistance compared to no assistance (P < .0001). In living donor (LD) transplants, the relative risk of mortality was 1.38 (0.78-2.42) for patients needing total assistance and 1.37 (1.14-1.65) for patients needing moderate assistance compared to patients who did not need assistance (0.003). PF is an independent predictor of post-transplant mortality. Assessment of older potential renal transplant recipients should include assessment and standardization of functional status to counsel about post-transplant survival.

Identifying Trends of Percutaneous Injuries at an Australian Dental School

ObjectivesThe aim of this study was to retrospectively examine trends in percutaneous exposure incidences (PEIs) at the School of Dentistry (SoD) from 2009 to 2019 and to report on the underreporting rate of PEIs, current attitudes, and awareness of PEI safety protocols from clinical staff and students at the SoD in 2019.MethodsRetrospective data were collected from deidentified archival incident reports from 2009 to 2019 from the SoD's incident reporting system (UQSafe and Legacy Database). Additionally, cross-sectional data were collected via the validated Percutaneous Exposure Incident Questionnaires (PEIQ) completed by clinical staff and students of the SoD in 2019.ResultsFrom the archival data, the majority (79.9%) of the 618 reported PEIs involved students. Local anaesthetic-related procedures were the most common cause in the archival (31.5%) and survey data (23.7%), whereas the needle-prick was the most common causative instrument in both data sets. Additionally, the finger was the most common site of injury found in the archival (53.0%) and survey data (52.8%). From 345 responses to the survey, 42.1% of PEIs sustained were not reported.ConclusionsStudents were at a higher risk of sustaining a PEI than staff members between 2009 and 2019. The reported knowledge on PEI classification and preventative measures is inadequate, suggesting that further PEI education is necessary. The study provides evidence of the trends in PEIs as well as data on the attitudes and awareness of student and staff at a dental teaching faculty to support the development of PEI safety management protocols.
