Disruptions in Sleep Health and Independent Associations with Psychological Distress in Close Family Members of Cardiac Arrest Survivors: A Prospective Study.

While recent guidelines have noted the deleterious effects of poor sleep on cardiovascular health, the upstream impact of cardiac arrest-induced psychological distress on sleep health metrics among families of cardiac arrest survivors remains unknown. Sleep health of close family members of consecutive cardiac arrest patients admitted to an academic center (8/16/2021 - 6/28/2023) was self-reported using the Pittsburgh Sleep Quality Index (PSQI). The baseline PSQI, focused on sleep in the month before cardiac arrest, was administered during hospitalization and repeated one month after cardiac arrest, alongside the Patient Health Questionnaire-8 (PHQ-8) to assess depression severity. Multivariable linear regressions analyzed associations between total PHQ-8 scores and changes in global PSQI scores between baseline and one month with higher scores indicating deterioration. A prioritization exercise explored potential interventions categorized into the family's information and well-being needs to reduce psychological distress. In our sample of 102 close family members (mean age 52±15 years, 70% female, 21% Black, 33% Hispanic), mean global PSQI scores showed a significant decline between baseline and one month after cardiac arrest (6.2±3.8 vs. 7.4±4.1; p<0.01). This deterioration was notable for sleep quality, duration, and daytime dysfunction. Higher PHQ-8 scores were significantly associated with higher change in PSQI scores, after adjusting for family members' age, sex, race/ethnicity, prior psychiatric history, and patient's discharge disposition [B=0.4 (95% C.I 0.24, 0.48); p<0.01, β=0.5]. Most families expressed a higher priority for information-based interventions over well-being needs to help alleviate psychological distress during the first month following cardiac arrest (76% vs. 34%, p<0.01). A significant sleep health decline was observed among close family members of cardiac arrest survivors during the acute period, with psychological distress associated with this disruption. Understanding these temporal associations will help guide the development of targeted interventions to support families during this uncertain time.

Effects of the Oncology Industrial Complex on Academic Cancer Centers

This Viewpoint outlines the missions of academic cancer centers and how they are being affected by the oncology industrial complex along with challenges and suggestions for an aligned way forward.

Use of medialized trochanteric-entry intramedullary nail to improve alignment in proximal femur nonunions.

Proximal femur shaft nonunion is a challenging problem, often occurring after malreduction that results in postoperative malalignment and decreased healing potential. Correction of malalignment is critical to achieving osseous union. Here we present a novel technique for treating proximal femur nonunions with varus malalignment using an intramedullary nail inserted through a medialized trochanteric entry point. Patients who underwent a proximal femur shaft (subtrochanteric or proximal third shaft) nonunion operation at a single level 1 academic referral centre by two attending surgeons between 1/1/2014 and 1/1/2022 were identified. Radiographic imaging was reviewed to determine initial fracture classification and calculation of coronal plane alignment (CPA), which was measured on preoperative, immediate postoperative, and final follow-up radiographs. Postoperative complications, reoperations, infections, and osseous union were also collected. Twenty-one patients with a mean age of 49.9 years (66% male) were identified. Mean preoperative CPA was 125.6 degrees, immediate postoperative mean CPA was 132.6 degrees, and mean final follow-up CPA was 131.5 degrees. Mean change in CPA from immediate postoperative films to final follow-up was a decrease of 0.4 degrees. 17 patients had follow up for a minimum of 12 months or until osseous union, and all achieved union without any major complications. Exchange nailing with an antegrade trochanteric entry nail through a medialized trochanteric starting point is a safe and effective technique in the treatment of proximal femur nonunions. This technique results in improved postoperative alignment that is sustained throughout the postoperative course, and may lead to increased rates of osseous union.

Self-Reported Patient and Provider Satisfaction With Neurology Telemedicine Visits After Rapid Telemedicine Implementation in an Urban Academic Center: Cross-Sectional Survey.

Many clinics and health systems implemented telemedicine appointment services out of necessity due to the COVID-19 pandemic. Our objective was to evaluate patient and general provider satisfaction with neurology telemedicine implementation at an urban academic medical center. Patients who had completed 1 or more teleneurology visits from April 1 to December 31, 2020, were asked to complete a survey regarding their demographic information and satisfaction with teleneurology visits. Providers of all specialties within the same hospital system were given a different survey to gather their experiences of providing telemedicine care. Of the estimated 1500 patients who had completed a teleneurology visit within the given timeframe, 117 (7.8%) consented to complete the survey. Of these 117 respondents, most appointments were regarding epilepsy (n=59, 50.4%), followed by multiple sclerosis (n=33, 28.2%) and neuroimmunology (n=7, 6%). Overall, 74.4% (n=87) of patients rated their experience as 8 out of 10 or higher, with 10 being the highest satisfaction. Furthermore, 75.2% (n=88) of patients reported missing an appointment in the previous year due to transportation issues and thought telemedicine was more convenient instead. A significant relationship between racial or ethnic group and comfort sharing private information was found (P<.001), with 52% (26/50) of Black patients reporting that an office visit is better, compared to 25% (14/52) of non-Black patients. The provider survey gathered 40 responses, with 75% (n=30) of providers agreeing that virtual visits are a valuable tool for patient care and 80% (n=32) reporting few to no technical issues. The majority of provider respondents were physicians on faculty or staff (n=21, 52%), followed by residents or fellows (n=15, 38%) and nurse practitioners or physician assistants (n=4, 10%). Of the specialties represented, 15 (38%) of the providers were in neurology. Our study found adequate satisfaction among patients and providers regarding telemedicine implementation and its utility for patient care in a diverse urban population. Additionally, while access to technology and technology literacy are barriers to telemedical care, a substantial majority of patients who responded to the survey had access to devices (101/117, 86.3%) and were able to connect with few to no technological difficulties (84/117, 71.8%). One area identified by patients in need of improvement was comfortability in communicating via telemedicine with their providers. Furthermore, while providers agreed that telemedicine is a useful tool for patient care, it limits their ability to perform physical exams. More research and quality studies are needed to further appreciate and support the expansion of telemedical care into underserved and rural populations, especially in the area of subspecialty neurological care.

Enhancement of early proximal caries annotations in radiographs: introducing the Diagnostic Insights for Radiographic Early-caries with micro-CT (ACTA-DIRECT) dataset

BackgroundProximal caries datasets for training artificial intelligence (AI) algorithms commonly include clinician-annotated radiographs. These conventional annotations are susceptible to observer variability, and early caries may be missed. Micro-computed tomography (CT), while not feasible in clinical applications, offers a more accurate imaging modality to support the creation of a reference-standard dataset for caries annotations. Herein, we present the Academic Center for Dentistry Amsterdam—Diagnostic Insights for Radiographic Early-caries with micro-CT (ACTA-DIRECT) dataset, which is the first dataset pairing dental radiographs and micro-CT scans to enable higher-quality annotations.MethodsThe ACTA-DIRECT dataset encompasses 179 paired micro-CT scans and radiographs of early proximal carious teeth, along with three types of annotations: conventional annotations on radiographs, micro-CT-assisted annotations on radiographs, and micro-CT annotations (reference standard). Three dentists independently annotated proximal caries on radiographs, both with and without micro-CT assistance, enabling determinations of interobserver agreement and diagnostic accuracy. To establish a reference standard, one dental radiologist annotated all caries on the related micro-CT scans.ResultsMicro-CT support improved interobserver agreement (Cohen’s Kappa), averaging 0.64 (95% confidence interval [CI]: 0.59–0.68) versus 0.46 (95% CI: 0.44–0.48) in its absence. Likewise, average sensitivity and specificity increased from 42% (95% CI: 34–51%) to 63% (95% CI: 54–71%) and from 92% (95% CI: 88–95%) to 95% (95% CI: 92–97%), respectively.ConclusionThe ACTA-DIRECT dataset offers high-quality images and annotations to support AI-based early caries diagnostics for training and validation. This study underscores the benefits of incorporating micro-CT scans in lesion assessments, providing enhanced precision and reliability.Graphical

Ulcerative Jejunitis in Celiac Disease: A Thirty-Year U.S. Experience.

Ulcerative jejunitis (UJ) or ulcerative enteritis (UE) is a rare complication of celiac disease (CeD). Guidelines regarding diagnosis and management are missing and these cases have seldom been reported in the United States. Single center case-series of CeD in which UE developed at a large academic center in the USA. Clinical presentation, diagnosis, treatment, and evolution of disease were collected. Eight cases were identified (6M/2F, mean age 59.5 (38-77) years). Presentations included intestinal obstruction (n=3), GI hemorrhage (n=3), and malabsorption (n=2). Ulcers were present in the duodenum in 4 patients, and exclusively past the angle of Treitz in only 4 cases, which makes the term ulcerative enteritis (UE) more appropriate than UJ. Six out of eight had T-cell receptor (TCR) clonal gene rearrangements and two had definite aberrant T cells. Corticosteroids were tried in all patients without improvement and 5 underwent surgical resection. Three patients received cladribine. One patient received an autologous stem cell transplant, followed by ruxolitinib. Two were subsequently diagnosed with enteropathy-associated T-cell lymphoma (EATL), including one with cerebral EATL, and 1 died from hemophagocytic syndrome. Two are still alive, including one only on GFD and two were lost to follow-up after surviving at least 30 months post treatment. UE seems a more appropriate term to describe an ulcerative complication of CeD at high risk of obstruction or bleeding. Steroids were not effective. Treatment outcomes were variable, but with a 50% death rate.

Long-Term Recurrence Risk, Metastatic Potential, and Length of Cystoscopic Surveillance of Low-Grade Non-Muscle-Invasive Bladder Cancer.

Patients with Ta low-grade (LG) NMIBC rarely develop metastases or die of it. Long-term data are scant and length of follow-up poorly defined. This retrospective study included 521 patients diagnosed with primary TaLG NMIBC (n = 491) or papillary urothelial neoplasm of low malignant potential (n = 30) from 1989 to 2019 at an academic center. Patient data were acquired using patient records chart review and a bladder cancer informatics registry at the center. Risk of recurrence and progression in stage, to muscle invasion, metastases, and death due to BC were analyzed. RNAseq assessed the transcriptomic profiles of 4 TaLG NMIBCs that metastasized. Interobserver variability in pathological grading (WHO 2004/2022 and 1973, n = 80) was blindly assessed by 3 expert pathologists. The median follow-up was 9.6 (95% CI: 8.6-10.2) years. Among 521 patients (73% men, median age 67.0 years), 350 recurred, 57 progressed in stage, 20 developed metastases, and 15 died of BC (median of 9.6 years after diagnosis). Cancer-specific survival probabilities were 0.99, 0.98, and 0.96 at 5, 10, and 15 years, respectively. Fifty patients who were recurrence free for the first 5 years developed late recurrences and 2 of them died of BC. Metastatic TaLG NMIBC had more adverse transcriptomic findings in keeping with higher grade tumors despite being phenotypically similar to indolent tumors. Grading concordance for the 2004/2022 system and WHO 1973 was 0.78 (95% CI: 0.65-0.90) and 0.41 (95% CI: 0.32-0.50), respectively. This study with long-term data challenges the assumption that primary TaLG NMIBC nearly never progresses to lethal disease if followed long enough. However, the risk of BC-related mortality is extremely low in patients who are recurrence-free for the first 5 years. Minimizing variability in pathological grading remains an unmet need.

Implementation of Primary Immune Thrombocytopenia Clinical Practice Guidelines for Management of Pregnancy.

Background: Managing primary immune thrombocytopenia (ITP) in pregnancy is challenging. Providers must balance bleeding risk against medication toxicity. The evaluation of the implementation of pregnancy-specific ITP clinical guidelines has not been widely studied. The goal of this study was to describe the implementation of pregnancy-specific ITP guidelines at an academic health center. Methods: We conducted a retrospective chart review at the University of Oklahoma Health system from 2011 to 2020. Descriptive statistics were calculated to summarize the characteristics of the study population. Management, according to the clinical guidelines (American Society of Hematology; American College of Obstetricians and Gynecologists) was evaluated during pregnancy and during/for delivery. Results: A total of 85 pregnant persons with ITP were included. The majority (68%; 58/85) delivered vaginally. There were 0 maternal deaths and 2 infant deaths. No patients had major bleeding during pregnancy. Postpartum hemorrhage was experienced by 14%. The management of thrombocytopenia during pregnancy was 100% adherent to the strong recommendation for severe (n = 13) and mild (n = 11) thrombocytopenia. However, 18/50 (36%) asymptomatic persons with moderate thrombocytopenia received treatment despite the strong recommendation that treatment was unnecessary. Additionally, 8/21 (38%) persons with moderate thrombocytopenia received treatment to increase platelet counts for epidural anesthesia despite the guideline's suggestion that it was unnecessary. Conclusions: During pregnancy, patients with severe thrombocytopenia (i.e., most at risk of bleeding) received treatment. On the other hand, approximately 40% of pregnant persons with ITP received unnecessary treatment for moderate asymptomatic thrombocytopenia either during pregnancy or for an epidural. Utilizing clinical practice guidelines would reduce the overtreatment of pregnant persons which would reduce the potential side effects of therapy for the mother and infant.

Perceptions of Lactation Experience Among Neurology Faculty and Impact of Lactation Time on Academic Achievement at U.S. Academic Medical Centers.

Objective: To investigate the perceptions of lactation experiences of neurology faculty and the impact of lactation time on academic achievement. Materials and Methods: This was a cross-sectional study utilizing a survey administered across 19 academic neurology centers in the United States. Respondents self-identified as having children and answered questions about lactation at work. Demographic information; academic achievement including publications, guest speakerships, awards, leadership roles, and funding; and perception of lactation experience were analyzed. Results: Among 162 respondents, 83% took lactation time at work. Thirty-seven percent reported lack of employer support for lactation, 46% were dissatisfied with their lactation experience, 59% did not receive compensation for lactation time, 62% did not have blocked clinical time, 73% reported relative value units were not adjusted to accommodate lactation, and 43% reported lack of access to private lactation space. Women spent on average 9.5 months lactating per child and desired 2.4 further months of lactation. There was no difference in all measures of self-reported academic achievement between women who did and did not take lactation time when measured across all career stages. Conclusions: Although a majority of respondents took lactation time at work, perceptions of employer support for lactation were low, and expectations for work productivity were not adjusted to accommodate lactation time. Taking lactation time at work did not decrease self-reported academic achievement. System-level best practices designed to support lactating faculty should be developed to guide academic institutions.

Report of cardiac electronic device implant complications over a 7-year study period

Abstract Background The global placement of cardiac implantable electronic devices (CIEDs) is on the rise. Complications linked to device implantation present a substantial burden on healthcare systems and patients alike. It is imperative to comprehend the complication rates associated with CIED procedures, enabling informed decision-making and strategic planning for patients, thereby enhancing the overall quality of care. Purpose We sought to determine post CIED implantation complication rates and provide operator specific complication data for quality assurance at our institution. Methods A comprehensive audit of all procedures completed between April 2016 to March 2023 by 14 high volume operators at a single academic center was completed. Complications and device data were extracted using electronic medical records. Complications evaluated include pneumothorax, infections, hematomas, venous thrombosis, lead perforation, and dislodgement using standardized definitions. Results During the 7-year period, a total of 9,467 procedures were completed. Among the cohort, 62% were male, with an average age of 74.6 ± 15.2 years. The procedural breakdown comprised 60% pacemakers, 19% ICDs, 16% CRTs and 3% ILRs. A total of 11,616 leads were implanted (3,644 RA leads and 1,110 LV leads). The overall complication rate was 3.1% (n=316): device pocket infection 0.68%, superficial infection 0.19%, lead dislodgement 0.53%, lead perforation 0.24%, pericardial effusion 0.1%, pneumothorax 0.15%, pocket hematoma 0.83%, DVT 0.36%, and hemothorax 0.02%. Complication rates per operator are shown in Figure-1. Conclusion Our findings indicate that the overall complication rates for CIED implants are lower than previously reported rates, and there is no significant difference between operators in overall rates of complication. This observation can be attributed to operator experience, advancements in peri-operative care and guideline-directed post-operative protocols. However, notable variations exist among operators in rates of pocket infection. The ongoing monitoring of CIED complications as a quality indicator remains a crucial benchmark, meriting annual assessments for ongoing evaluation.

Safe and favorable prognosis of thoracic endovascular aortic repair for the low-risk patients with non-acute type B aortic dissection.

Preemptive thoracic endovascular aortic repair (TEVAR) has the potential to improve the prognosis of Stanford type B aortic dissection (TBAD), however it is important to determine whether it could be safely performed as a prophylactic treatment. This study aimed to determine the short- and long-term outcomes of preemptive TEVAR for uncomplicated TBAD with a small aortic aneurysm. Retrospective multicenter analysis. We analyzed 212 patients with medically treated uncomplicated subacute TBAD between July 2004 and October 2019 in two Japanese academic centers. The short- and long-term prognosis of patients who underwent preemptive TEVAR and the changes in aortic diameter over time after TEVAR were analyzed. Aorta-related complications, aortic-related death and postoperative complications were recorded and analyzed. Analysis was performed on an intension-to-treat basis. During follow-up, patients were divided into two groups: optimal medical treatment [OMT; n = 185 (87%)] and preemptive TEVAR [n = 27 (13%)]. In all cases, aortic enlargement was the reason for therapeutic intervention in the preemptive TEVAR group. Propensity score matching yielded a cohort of 27 control patients with OMT (group A) and 27 patients who underwent preemptive TEVAR (group B). Preoperative characteristics were similar between groups. In group B, only one patient developed type A dissection at a late stage and died from aortic rupture. Freedom from aortic-related death at 1/5/10 years was 100%/92%/92% in group B. Overall growth (mm/year) of max aorta was significantly smaller in the TEVAR group than in the control group (-3.7 ± 2.9 vs. 0.4 ± 5.6, p < 0.01), and the diameter of the false lumen was reduced (-8 ± 4.8 vs. -1.3 ± 8.0, p < 0.001). Short- and long-term outcomes of TEVAR for uncomplicated TBAD with a small aortic aneurysm were excellent, with few postoperative complications. After TEVAR, aortic remodeling was observed in the short term, suggesting that it may contribute to the prevention of aortic-related death due to rupture.

The underestimated risk of prediabetes on cardiovascular outcomes in heart failure with reduced left ventricular function

Abstract Background The global prevalence of prediabetes and diabetes is increasing, highlighting an urgent public health challenge. While the cardiovascular (CV) risk of diabetes is well studied, profound data on the CV risk of prediabetes in patients with heart failure (HF) remain scarce in current literature. Therefore, we aimed to investigate the relationship of prediabetes and diabetes with common HF associated events such as all-cause, CV death and hospitalization for HF (HHF) in patients with HF with reduced ejection fraction (HFrEF). Methods Patients with HFrEF who were admitted to a tertiary academic center between 01/2005 and 07/2019 were included in the present analysis and then stratified according to their glycemic state. Prediabetes was defined as an HbA1c value between 5.7% and 6.4% and the absence of diabetes mellitus. The primary outcome was a composite of CV death and HHF. Secondary outcomes were the individual components of the primary outcome and all-cause death. We used cox regression models adjusted for age, sex, chronic kidney disease, body mass index, prior myocardial infarction, hypertension, CRP, and LDL-C. Results In total, 1,777 patients (median age 69 years, 24.3% female) were included in the present analysis and followed over a median of 4 years. Among them, 35.2% were diabetic, 18.7% prediabetic, and 46.1% showed non-impaired glucose metabolism. NT-proBNP levels were comparable between all glycemic groups. Both prediabetes and diabetes were found to significantly increase the risk of CV-death or HHF compared to those with normal glucose metabolism, with adjusted hazard ratios (HR) of 1.41 (95% Confidence Interval [CI]: 1.05-1.89) and 1.52 (95% CI: 1.17-1.97), respectively. This elevated risk applied to both components of the primary outcome, as illustrated in Figure 1. Notably, the increased risk of all-cause mortality was statistically significant only among diabetic patients (adj. HR 1.75; 95%CI: 1.30-2.36), with prediabetic patients showing a trend towards increased risk but not reaching statistical significance (adj. HR 1.40; 95%CI: 0.99-1.97). Conclusion The findings of this study underscores the independent associations between both prediabetes and diabetes with increased risks of cv-death and HHF in patients diagnosed with HFrEF. This emphasizes the critical role of glycemic status in the prognostication and management of HFrEF. The associations suggest that prediabetes is not merely a transient or benign state but has significant implications for cardiovascular health, particularly in the context of HF. In light of these findings, screening of prediabetes in patients with HFrEF might help to identify patients at risk who are susceptible for the development of HF related adverse events.Forest plot for all study endpointsKaplan-Meier curves for CV-death/HHF

Pupillary Peaking & Presence of Dysphotopsias Following Glaucoma Tube Shunt Surgery

ABSTRACT Purpose To describe the presence of pupillary peaking and dysphotopsias in a sample of eyes following glaucoma drainage device (GDD) surgery. Methods Cross-sectional analysis of 68 glaucoma patients with GDD, 45 patients with glaucoma and no GDD, and 50 control patients was conducted in a single academic center. Patients with an appropriate diagnosis that met the inclusion criteria were asked to enroll in the study. All patients received an 8-item dysphotopsia questionnaire and were age-matched. Photographs of pupils were taken to assess pupillary peaking. One-way analysis of variance (ANOVA) testing was performed for statistical analysis. Results Of the 68 patients with GDD, 25 (36.76%) had pupillary abnormalities with peaking most commonly occurring in the direction of the tube entry superotemporally, and 50 (73.53%) had reported one or more dysphotopsias. In patients reporting one or more dysphotopsias, the rate of lines, crescents, ghost images, and shadows was significantly higher when compared to glaucoma patients without GDD and control patients (p < .01). This corresponded to a lower best-corrected visual acuity in the GDD group compared to the glaucoma and control groups (p < .001). Conclusions Over a third of glaucoma patients receiving GDD had pupillary abnormalities, and nearly 3 out of 4 patients with GDD reported one or more dysphotopsias when compared to glaucoma patients without GDD and an age-matched control group. Glaucoma specialists and patients should be aware of these complications when proceeding with GDD surgery.

Incidence of acute cardiovascular hospitalizations and association with hemodynamic biomarkers in cancer patients treated with Immune Checkpoint Inhibitor therapy

Abstract Background/Introduction Immune checkpoint inhibitors (ICI) have significantly improved outcomes for several malignancies. Despite these benefits, patients with cancer face an increased risk for the development of cardiovascular disease due to mutual risk factors, similar biological mechanisms, as well as cardiotoxic side effects of therapy. Therefore, there is a pressing need for effective risk stratification strategies. Purpose This study aimed to explore the association between NT-proBNP levels and the risk of acute cardiovascular hospitalizations and death in patients who receive ICI. Methods We used electronic health records of patients treated with ICI who had available baseline NT-proBNP levels at our hospital, a tertiary academic center, between January 2017 and July 2022. The primary outcome of interest was the composite of acute cardiovascular hospitalization or death. The associations between NT-proBNP and outcomes were analyzed using cox regression models adjusted for age, sex, serum creatinine, diabetes, HF, CAD, hypertension, AF, LDL-C, and CRP. Results In total, 550 patients (35% female, median age 65 yrs) were included in the study. The median NT-proBNP levels were 272 pg/mL (IQR 102-742 pg/mL) and 388 (71%) patients had NT-proBNP levels ≥125 pg/mL. During a median FU of 67 weeks, 190 patients (35%) died, and 103 CV hospitalizations occurred in 76 patients (14%). Compared with patients with NT-proBNP concentrations &amp;lt;125, those with NT-proBNP concentrations ≥125 pg/ml had significantly higher event rates of the combined endpoint (12-Month KM event rates: 38% vs 21%, P&amp;lt;0.001). After multivariable adjustment, NT-proBNP remained independently associated with an increased risk of cardiovascular hospitalization and death (Adjusted HR for 1-SD increase in log-transformed biomarker 1.64, 95% CI 1.24 to 2.14; Figure). Conclusion These data highlight NT-proBNP levels as a valuable marker for identifying patients at increased risk of cardiovascular complications during ICI therapy.

Optimal anticoagulation strategy for left ventricular assist device patients undergoing thoracentesis: a retrospective study

Abstract Background Left ventricular assist devices (LVADs) are associated with thromboembolic risks necessitating anticoagulation, yet balancing these risks with bleeding concerns remains challenging. Current practice involves warfarin with a target INR of 2-3 alongside anti-platelet therapy. However, consensus on anticoagulation management is lacking, particularly during sub-therapeutic INR or procedural settings. Common strategies include bridging anticoagulation with heparin or enoxaparin, temporary cessation of anticoagulation during the procedure or uninterrupted anticoagulation. Purpose To evaluate and compare the incidence of bleeding and thromboembolic events in LVAD patients undergoing thoracentesis, with a focus on determining the optimal anticoagulation strategy during procedures. Methods Retrospective data was collected over one year from LVAD patients undergoing thoracentesis at a large academic center. Patients were categorized into ‘bridge’ (received intravenous heparin for bridging during thoracentesis) and ‘no-bridge’ (did not receive bridging anticoagulation) groups. Warfarin was paused before procedure and resumed after procedure in both groups. Baseline characteristics, including age, sex, race, BMI, LVAD type, and INTERMACS profile, were recorded. Primary outcomes were major bleeding and thromboembolic events within 30 days of warfarin cessation. Statistical analysis used t-test/Wilcoxon for continuous variables and Chi-square/Fisher exact test for categorical variables. A p-value &amp;lt;0.05 was considered significant. Results During the study, twenty LVAD patients underwent thirty-two thoracenteses (nineteen bridge, thirteen no-bridge). The demographics were similar among the two groups. Warfarin was held for an average of 5.5 ± 4.6 days before and resumed 4.1 ± 4.6 days after the procedure in the bridge group and 3.8± 3.2 days before and 1.7 ± 2.5 days after in the no-bridge group. Major bleeding occurred in 73.7% of bridge group cases versus 30.8% of no-bridge group cases (p=0.059). 63.2% of bridge group patients had a bloody pleural effusion on thoracentesis compared to 46.2% of no-bridge group patients (p value= 0.34). Average transfusion requirements were 2.8 units and 2 units in the bridge and the no-bridge groups respectively (p=0.658). Thromboembolic events included a 10.5% ischemic CVA rate in the bridge group, with none in the no-bridge group. No other arterial thromboembolic events, pump thrombosis or DVT/PE were observed in either group. Conclusion In LVAD patients undergoing thoracentesis, a non-bridging strategy does not appear to elevate the risk of thrombosis compared to a bridging approach. Moreover, the incidence of bleeding, while not statistically significant, trended higher in the bridging group.

A review of the use of CT pulmonary angiography in pregnant and postpartum women at an academic centre

Background Pulmonary embolism (PE) is a common cause of maternal death during pregnancy and the puerperium yet data on its prevalence in middle-income countries is lacking. Methods We examined the medical records and CTPA (computed tomography pulmonary angiography) images of 67 women in an obstetric high care unit during pregnancy and the puerperium. We aimed to determine the prevalence of PE in a high-risk obstetric population undergoing CTPA, assess associated clinical features in this cohort, and determine the prevalence of alternative CT findings. Results CTPA detected PE in 11 women (16.42%) and alternative CT findings in 46 (68.6%). Women with PE had a lower systolic blood pressure than those without PE ( P = 0.001). Multiple gestation, preterm rupture of membranes, and gestational diabetes were linked to higher PE prevalence. Conclusions This study, set in an upper middle-income country, demonstrated a higher CTPA yield for PE and alternative diagnoses than in international literature, emphasising context-specific assessments.

Alterations in taste preferences one year following sleeve gastrectomy, Roux-en-Y gastric bypass, and one anastomosis gastric bypass: a cross-sectional study

The influence of metabolic and bariatric surgery (MBS) on taste preferences and the pleasurable aspects of appetite may be mediated through its effects on gut hormones, potentially affecting weight loss results. Research indicates that the nature of the MBS performed significantly impacts food cravings in the year following the procedure, with no clear relationship to psychological factors or pre-surgery eating behaviors. During the period from August 2021 to August 2022, a group of adult patients with a body mass index (BMI) of 40 kg/m2 or above, or 35 kg/m2 or above with obesity-related medical complications, underwent Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), or sleeve gastrectomy (SG) at a tertiary academic center focused on MBS. This research included 294 patients who completed the Taste Desire and Enjoyment Change Questionnaire (TDECQ) one year after their surgical procedures, which were primary RYGB, OAGB, or SG. Most participants noted changes in their taste perception, cravings, and enjoyment of flavors after undergoing SG, RYGB, and OAGB. The study’s findings suggest that the type of MBS significantly affects taste preferences. Additionally, RYGB and OAGB were associated with a more substantial decrease in the craving for sweet and fatty flavors relative to SG.

Using Mortality and Morbidity Conferences in Advanced Practice Nurse Education to Enhance Student Self-Efficacy.

The integration of morbidity and mortality (M and M) conferences into advanced practice nurse (APN) nursing curricula is a novel approach aimed at enhancing education, reflective learning, and continuous improvement. M and M conferences have traditionally been a standard practice for medical specialties, yet a gap exists in their utilization within APN education. A quasiexperimental pilot study with 20 student registered nurse anesthetists was conducted at a large urban academic center. The General Self-Efficacy Scale was utilized to evaluate student self-efficacy and confidence in managing adverse events. Significant improvement in self-efficacy scores (p = .003) postintervention indicated the educational benefits of M and M conferences. All participants reported increased confidence in navigating unexpected events. The M and M conference is a valuable tool within APN education for cultivating self-efficacy and confidence in navigating adverse events. [J Nurs Educ. 2024;63(X):XXX-XXX.].

Overlapping conditions in Long COVID at a multisite academic center.

Many patients experience persistent symptoms after COVID-19, a syndrome referred to as Long COVID (LC). The goal of this study was to identify novel new or worsening comorbidities self-reported in patients with LC. Patients diagnosed with LC (n = 732) at the Mayo Long COVID Care Clinic in Rochester, Minnesota and Jacksonville, Florida were sent questionnaires to assess the development of new or worsening comorbidities following COVID-19 compared to patients with SARS-CoV-2 that did not develop LC (controls). Both groups were also asked questions screening for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), generalized joint hypermobility (GJH) and orthostatic intolerance. 247 people with LC (33.7%) and 40 controls (50%) responded to the surveys. In this study LC patients averaged 53 years of age and were predominantly White (95%) women (75%). The greatest prevalence of new or worsening comorbidities following SARS-CoV-2 infection in patients with LC vs. controls reported in this study were pain (94.4% vs. 0%, p < 0.001), neurological (92.4% vs. 15.4%, p < 0.001), sleep (82.8% vs. 5.3%, p < 0.001), skin (69.8% vs. 0%, p < 0.001), and genitourinary (60.6% vs. 25.0%, p = 0.029) issues. 58% of LC patients screened positive for ME/CFS vs. 0% of controls (p < 0.001), 27% positive for GJH compared to 10% of controls (p = 0.026), and a positive average score of 4.0 on orthostatic intolerance vs. 0 (p < 0.001). The majority of LC patients with ME/CFS were women (77%). We found that comorbidities across 12 surveyed categories were increased in patients following SARS-CoV-2 infection. Our data also support the overlap of LC with ME/CFS, GJH, and orthostatic intolerance. We discuss the pathophysiologic, research, and clinical implications of identifying these conditions with LC.
