Impact of Intraoperative Fluctuations of Cardiac Output on Cerebrovascular Autoregulation: An Integrative Secondary Analysis of Individual-level Data.

BACKGROUND: Intraoperative impairment of cerebral autoregulation (CA) has been associated with perioperative neurocognitive disorders. We investigated whether intraoperative fluctuations in cardiac index are associated with changes in CA. METHODS: We conducted an integrative explorative secondary analysis of individual-level data from 2 prospective observational studies including patients scheduled for radical prostatectomy. We assessed cardiac index by pulse contour analysis and CA as the cerebral oxygenation index (COx) based on near-infrared spectroscopy. We analyzed (1) the cross-correlation between cardiac index and COx, (2) the correlation between the time-weighted average (TWA) of the cardiac index below 2.5 L min-1 m-2, and the TWA of COx above 0.3, and (3) the difference in areas between the cardiac index curve and the COx curve among various subgroups. RESULTS: The final analysis included 155 patients. The median cardiac index was 3.16 [IQR: 2.65, 3.72] L min-1 m-2. Median COx was 0.23 [IQR: 0.12, 0.34]. (1) The median cross-correlation between cardiac index and COx was 0.230 [IQR: 0.186, 0.287]. (2) The correlation (Spearman ρ) between TWA of cardiac index below 2.5 L min-1 m-2 and TWA of COx above 0.3 was 0.095 (P=0.239). (3) Areas between the cardiac index curve and the COx curve did not differ significantly among subgroups (<65 vs. ≥65 y, P=0.903; 0 vs. ≥1 cardiovascular risk factors, P=0.518; arterial hypertension vs. none, P=0.822; open vs. robot-assisted radical prostatectomy, P=0.699). CONCLUSIONS: We found no meaningful association between intraoperative fluctuations in cardiac index and CA. However, it is possible that a potential association was masked by the influence of anesthesia on CA.

Novel and Off-Label Biologic Use in the Management of Hidradenitis Suppurativa, Pyoderma Gangrenosum, Lichen Planus, and Seborrheic Dermatitis: A Narrative Review.

With advances in drug development and our understanding of the pathophysiology of skin disease, biologic medications have emerged as powerful management tools for dermatologists. While biologics have most often been used in the management of psoriasis, they are being used off-label for the management of a variety of other immune-mediated skin diseases with overlapping molecular targets. This narrative review focuses on the novel and off-label use of biologic medications for the management of hidradenitis suppurativa (HS), pyoderma gangrenosum (PG), lichen planus (LP), and seborrheic dermatitis (SD). Review of the literature revealed that IL-17, IL-23, and tumor necrosis factor (TNF) inhibitors were being used across a variety of immune-mediated skin pathologies with variable efficacy, among other targeted biologics. While biologics were generally safe in the treatment of primary immune-mediated skin disorders, paradoxical disease eruptions were noted with biologic use and were theorized to occur owing to immune dysregulation and cytokine imbalance. While numerous case reports show promise for the use of biologics in immune-mediated skin pathologies, the variable efficacy and safety reported warrants more thorough investigations of the role of these targeted medications in comprehensive disease management.

Current Knowledge and Opinions of Medical Trainees Regarding PSA Screening.

After 2008 and 2012 USPSTF recommendations against PSA screening, studies revealed a decline in screening rates and trend towards more advanced disease at presentation. After revision of this recommendation in 2017, PSA screening guidelines remain inconsistent and controversy still exists about its clinical utility. We seek to better understand the knowledge of medical trainees regarding this fundamental controversy and gain better insight into what they are being taught regarding this topic. Participants were medical students (n = 66) and residents (n = 60) from a single institution. REDCap software was used for informed consent, survey distribution, and data collection. Variables measured included PSA clinical knowledge, awareness of the PSA guideline changes, and attitudes, confidence, and viewpoints on use of PSA screening in clinical practice. More than 60% of medical trainees reported little or no knowledge of PSA screening guidelines. Although residents reported more knowledge than medical students, actual assessed knowledge of PSA screening did not differ between groups. Trainees reported receiving education primarily from other healthcare professionals and didactics, with some self-learning online. Though confidence was low overall, residents were more confident than medical students in discussing PSA screening with patients. The majority of respondents wanted more information about PSA testing, with medical students particularly interested in diagnosis/detection, treatment, and survival. Overall, opinions towards PSA testing as an aid were generally positive. Better education about the current PSA screening guidelines for medical trainees is imperative, particularly given that shared decision-making is of great importance when counseling patients on cancer screening.

Risk factors, demographic profiles, and management of uncomplicated recurrent urinary tract infections: a single institution study.

OBJECTIVE: Recurrent urinary tract infections (rUTI) are a common urologic chief complaint. Although rUTIs are a significant burden on the healthcare system, until recently there were no published guidelines to delineate optimal management of this condition. The objective of this study was to describe the demographic profile of rUTI patients and summarize practice patterns at a single tertiary health center, as well as to assess whether our real-life practice patterns parallel the recently published guidelines. METHODS: We conducted a retrospective record review of female patients presenting for diagnosis of uncomplicated rUTI/cystitis between October 2010 and September 2018. Analyses were conducted to investigate (a) whether pre- versus postmenopausal women differed in their risk factors for rUTI, (b) whether providers adjust their practice patterns when treating pre- versus postmenopausal women with rUTIs, and (c) whether certain treatment regimens led to lower rates of rUTI than others. RESULTS: Of the 125 cases included in the final analysis, pre- versus postmenopausal women did differ in their risk factors for rUTI, specifically age, Charlson Comorbidity Index score, and comorbidities. Although common treatments were found across menopausal status, providers did adjust their practice patterns when treating pre- versus postmenopausal women, including the use of postcoital suppression, conservative measures, cranberry juice/extract, and probiotics for premenopausal women and daily suppression and vaginal estrogens for postmenopausal women. rUTI after treatment (<40%) was highest after the use of conservative measures for all women and rates of rUTI after treatment generally did not differ as a function of menopausal status, but rather by treatment option. CONCLUSIONS: This single institution report sheds light on practice patterns at a major academic center, specifically as it compares to the new American Urological Association guidelines and the use of estrogen cream for postmenopausal women.
