Associations of cephalad drainage in neonatal veno-venous ECMO - A mixed-effects, propensity score adjusted retrospective analysis of 20 years of ELSO data.

BACKGROUND: Neurologic complications can occur during neonatal Veno-Venous (VV) ECMO. The addition of a cephalad drainage cannula (i.e., VVDL+V) to dual lumen cannulation (i.e., VVDL) has been advocated to reduce such complications, but previous studies have presented mixed results. METHODS: Data from the ECMO Registry of the Extracorporeal Life Support Organization was used to extract all neonates (≤28 days old) who underwent VV ECMO for respiratory support between 2000 and 2019. Primary outcomes were mortality, conversion to Veno-Arterial (VA) ECMO, pump flows, and complications. A mixed-effects, propensity score adjusted analysis was performed. RESULTS: 4,275 neonates underwent VV ECMO, 581 (13.6%) via VVDL+V cannulation, and 3,694 (86.4%) via VVDL. On unadjusted analyses, VVDL+V patients had higher rates of mortality (25.5% vs 19.0%, p<0.001), conversion to VA ECMO (14.5% vs 4.1%, p<0.001), and higher pump flows at 4 h from ECMO initiation (112.7 vs 105.5 mL/Kg/min, p<0.001), but lower at 24 h (100.3 vs 104.0 mL/Kg/min, p = 0.004), and a higher proportion of them experienced hemorrhagic (29.3% vs 18.3%, p<0.001), cardiovascular (60.8% vs 45.8%, p<0.001), and mechanical (42.5% vs 32.6%, p<0.001) complications compared to VVDL patients. After adjusting for propensity scores and the multi-level nature of ELSO data, there were no differences in neurologic outcomes, pump flows, or mortality. Rather, VVDL+V cannulation was associated with higher rates of conversion to VA ECMO (adjusted odds ratio [AOR] 43.3, 95% CI 24.3 - 77.4, p<0.001), and increased mechanical (AOR 2.2, 95% CI 1.6 - 3.0, p<0.001) and hemorrhagic (AOR 2.0, 95% CI 1.4 - 3.0, p<0.001) complications. CONCLUSIONS: In this analysis, VVDL+V cannulation was not associated with any improvement in neurologic outcomes, pump flows, or mortality, but was rather associated with higher rates of conversion to Veno-Arterial ECMO, mechanical, and hemorrhagic complications.

Inpatient Satisfaction With Surgical Resident Care After Elective General and Oncologic Surgery.

OBJECTIVE: To investigate inpatient satisfaction with surgical resident care. BACKGROUND: Surgical trainees are often the primary providers of care to surgical inpatients, yet patient satisfaction with surgical resident care is not well characterized or routinely assessed. METHODS: English-speaking, general surgery inpatients recovering from elective gastrointestinal and oncologic surgery were invited to complete a survey addressing their satisfaction with surgical resident care. Patients positively identified photos of surgical senior residents and interns before completing a modified version of the Consumer Assessment of Healthcare Providers and Systems Surgical Care Survey (S-CAHPS). Adapted S-CAHPS items were scored using the "top-box" method. RESULTS: Ninety percent of recruited patients agreed to participate (324/359, mean age=62.2, 50.3% male). Patients were able to correctly identify their seniors and interns 85% and 83% of the time, respectively ( P =0.14). On a 10-point scale, seniors had a mean rating of 9.23±1.27 and interns had a mean rating of 9.01±1.49 ( P =0.14). Ninety-nine percent of patients agreed it was important to help in the education of future surgeons. CONCLUSIONS: Surgical inpatients were able to recognize their resident physicians with high frequency and rated resident care highly overall, suggesting that they may serve as a willing source of feedback regarding residents' development of core competencies such as interpersonal skills, communication, professionalism, and patient care. Future work should investigate how to best incorporate patient evaluation of surgical resident care routinely into trainee assessment to support resident development.

Peripheral T-Cells, B-Cells, and Monocytes from Multiple Sclerosis Patients Supplemented with High-Dose Vitamin D Show Distinct Changes in Gene Expression Profiles.

Vitamin D is a steroid hormone that has been widely studied as a potential therapy for multiple sclerosis and other inflammatory disorders. Pre-clinical studies have implicated vitamin D in the transcription of thousands of genes, but its influence may vary by cell type. A handful of clinical studies have failed to identify an in vivo gene expression signature when using bulk analysis of all peripheral immune cells. We hypothesized that vitamin D's gene signature would vary by immune cell type, requiring the analysis of distinct cell types. Multiple sclerosis patients (n = 18) were given high-dose vitamin D (10,400 IU/day) for six months as part of a prospective clinical trial (NCT01024777). We collected peripheral blood mononuclear cells from participants at baseline and again after six months of treatment. We used flow cytometry to isolate three immune cell types (CD4+ T-cells, CD19+ B-cells, CD14+ monocytes) for RNA microarray analysis and compared the expression profiles between baseline and six months. We identified distinct sets of differentially expressed genes and enriched pathways between baseline and six months for each cell type. Vitamin D's in vivo gene expression profile in the immune system likely differs by cell type. Future clinical studies should consider techniques that allow for a similar cell-type resolution.

Medical Students and the Drive for a Single Right Answer: Teaching Complexity and Uncertainty.

The arrival of Generation Z, the next generation of medical learners, has been accompanied by efforts to adapt teaching practices for this new group of students. Many have identified challenges associated with addressing the needs of modern medical learners. One particular trend we have observed is that medical students are increasingly requesting an "answer key" for all aspects of their medical education. Students often expect to have the correct answers readily available to them to ensure they have reached the correct conclusion and to determine the precise knowledge they need to master. Yet, for much of medicine, and particularly in the care of critically ill patients with multisystem disease in intensive care units, answers are uncertain, and the body of knowledge is ever-growing. Students' regular requests for solutions to be provided to them threaten to undermine their development into critically thinking, self-sufficient physicians. We outline three potential contributors to this multifactorial problem and offer corresponding pedagogical solutions. Specifically, we address how prioritizing outcomes over process, discomfort with uncertainty, and fear of faltering can cause students to seek excessive levels of support that may ultimately do more harm than good. Addressing students' concerns in these three key areas will not only serve students well during their undergraduate medical training but will also equip them with the skills needed to succeed in the clinical realm. To produce physicians capable of navigating an increasingly uncertain world, medical educators will need to help students appreciate that finding the answer is more complex than being provided an answer key.

A multisite study of medical student perspectives on the core surgical clerkship.

BACKGROUND: The surgical clerkship is the primary surgical learning experience for medical students. This study aims to understand student perspectives on the surgery clerkship both before and after the core surgical rotation. METHODS: Medical students at 4 academic hospitals completed pre and postclerkship surveys that included open-ended questions regarding (1) student learning goals and concerns and (2) how surgical clerkship learning could be enhanced. Thematic analysis was performed, and interrater reliability was calculated. RESULTS: Ninety-one percent of students completed both a pre and postclerkship survey (n =162 of 179), generating 320 preclerkship and 270 postclerkship responses. Mean kappa coefficients were 0.83 and 0.82 for pre and postclerkship primary themes, respectively. Thematic analysis identified 5 broad themes: (1) core learning expectations, (2) understanding surgical careers, culture, and work, (3) inhabiting the role of a surgeon, (4) inclusion in the surgical team, and (5) the unique role of the medical student on clinical clerkships. Based on these themes, we propose a learner-centered model of a successful surgical clerkship that satisfies discrete student learning and goals and career objectives while ameliorating the challenges of high-stakes clinical surgical environments such as the operating room. CONCLUSION: Understanding student perspectives on the surgery clerkship, including preclerkship motivations and concerns and postclerkship reflections on surgical learning, revealed potential targets of intervention to improve the surgery clerkship. Future investigation may elucidate whether the proposed model of the elements of a successful surgery clerkship learning facilitates improvement of the surgical learning environment and enhanced surgical learning.

Non-English Primary Language is Associated with Emergency Surgery for Diverticulitis.

BACKGROUND: Language barriers can limit access to care for patients with a non-English primary language (NEPL). The objective of this study was to define the association between primary language and emergency versus elective surgery among diverticulitis patients. MATERIALS AND METHODS: Retrospective cohort study of adult patients from the 2009-2014 New Jersey State Inpatient Database. Patients were included if they had primary language data and underwent a partial colon resection for diverticulitis. Primary language was dichotomized into NEPL versus English primary language (EPL). The primary outcome was surgical admission type - urgent/emergent (referred to as "emergency") versus elective. Descriptive and multivariable analyses were performed. RESULTS: A total of 9,453 patients underwent surgery for diverticulitis, of which 592 (6.3%) had NEPL. Among NEPL patients, 300 (51%) had Spanish as primary language and 292 (49%) had another non-Spanish primary language. Patients with NEPL and EPL were similar in age (median age 58 versus 59 years; P = 0.54) and sex (52% versus 53% female; P = 0.45). Patients with NEPL were less likely to have commercial insurance (45% versus 59%; P <0.001). On multivariable analysis, compared to patients with EPL, NEPL was associated with increased odds of emergency surgery for diverticulitis (OR 1.35; 95% Confidence Interval 1.13-1.62; P = 0.001) CONCLUSION: Patients with NEPL have higher odds of emergency versus elective surgery for diverticulitis compared to patients with EPL. Further research is needed to examine differences in referral pathways, patient-provider communication, and health literacy that may hinder access to elective surgery in patients with diverticulitis.

Non-English Primary Language Is Associated with Short-Term Outcomes After Supratentorial Tumor Resection.

BACKGROUND: Despite research indicating that patients with non-English primary language (NEPL) have increased hospital length of stay (LOS) for craniotomies, there is a paucity of neurosurgical research examining the impact of language on short-term outcomes. This study sought to evaluate short-term outcomes for patients with English primary language (EPL) and NEPL admitted for resection of a supratentorial tumor. METHODS: Using the Agency for Healthcare Research and Quality Healthcare Cost and Utilization Project New Jersey State Inpatient Database, this study included patients 18-90 years old who underwent resection of a supratentorial primary brain tumor, meningioma, or brain metastasis from 2009 to 2017. The primary outcomes were total, preoperative, and postoperative LOS. Secondary outcomes were complications, mortality, and discharge disposition. Univariable and multivariable analyses compared Spanish primary language (SPL), non-English non-Spanish (NENS) primary language, and EPL groups. RESULTS: A total of 7324 patients were included: 2962 with primary brain tumor, 2091 with meningioma, and 2271 with brain metastasis. Patients with SPL (n = 297) were younger and more likely to have noncommercial insurance, lower income, and fewer comorbidities. Patients with NENS (n = 257) had similar age and comorbidities to the EPL group but had a greater proportion of noncommercially insured and low-income patients (P < 0.001). Multivariable analysis showed that patients with NENS had increased postoperative LOS (adjusted incidence rate ratio, 1.10; P = 0.008) and higher odds of a complication (adjusted odds ratio, 1.36; P = 0.015), and patients with SPL had higher odds of being discharged home (adjusted odds ratio, 1.55; P = 0.017). CONCLUSIONS: Patients with NEPL have different short-term outcomes after supratentorial tumor resection that varies based on primary language. More research is needed to understand the mechanisms driving these findings and to clarify unique experiences for different populations with NEPL.

The role of patient primary language in access to brain tumor resection: Evaluating emergent admission and hospital volume.

BACKGROUND: This study investigated the effect of limited English proficiency on access to neuro-oncologic surgery. We compared rates of emergent/urgent admission and admission to high-volume hospitals for English and non-English primary language patients with brain neoplasms. METHODS: Using the AHRQ-HCUP New Jersey State Inpatient Database, we included patients 18-90 years old who underwent resection of a supratentorial primary brain tumor (PBT), meningioma (MA) or brain metastasis (BM) from 2009-2017. Outcomes were emergent/urgent admission and annual hospital procedure volume. Univariable and multivariable analyses compared Spanish (SPL), Non-English Non-Spanish (NENS), and English (EPL) primary language groups. RESULTS: 7,402 patients were included: 2,996 PBT, 2,115 MA, and 2,291 BM. SPL patients (n = 300) were younger and had a greater proportion of non-commercially insured, low-income patients with lower comorbidity scores. NENS patients (n = 260) had similar age and comorbidity scores as EPL patients, but a greater proportion had non-commercial insurance and low income (p < 0.001). Multivariable analysis revealed NENS, but not SPL, patients had increased odds of emergent/urgent admission (2.10(1.50-2.93), p < 0.001), but demonstrated no association between admission to higher volume centers and primary language. CONCLUSION: Patient primary language may influence access to timely neurosurgical care, but access to high-volume centers appears to be mediated by other factors. POLICY SUMMARY STATEMENT: In addition to efforts to improve health care access for patients with limited English proficiency, multilingual health literacy and patient education interventions may help to promote timely presentation for brain tumor resection among this vulnerable patient population.

Protecting Our Own: Equity for Employees as Hospitals Battle COVID-19.

As medical providers garner praise during the coronavirus disease 2019 (COVID-19) pandemic, "nonclinical" health care workers remain largely overlooked. Although these essential workers face similar, if not greater, risks of contracting severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as others on the frontlines, many hospitals have fallen short in providing this vulnerable population with needed protections. Instead, hospitals should implement policies that guarantee all staff receive the information, equipment, and support necessary for battling the current crisis. This is critical not only for promoting the safety of these workers and their families, but also for ensuring the well-being of the community as a whole.

Telemedicine, COVID-19, and disparities: Policy implications.

While the rapid expansion of telemedicine in response to the COVID-19 pandemic highlights the impressive ability of health systems to adapt quickly to new complexities, it also raises important concerns about how to implement these novel modalities equitably. As the healthcare system becomes increasingly virtual, it risks widening disparities among marginalized populations who have worse health outcomes at baseline and limited access to the resources necessary for the effective use of telemedicine. In this article, we review recent policy changes and outline important recommendations that governments and health care systems can adopt to improve access to telemedicine and to tailor the use of these technologies to best meet the needs of underserved patients. We suggest that by making health equity integral to the implementation of telemedicine now, it will help to ensure that all can benefit from its use going forward and that this will be increasingly integral to care delivery.

NIRS-Based Hyperscanning Reveals Inter-brain Neural Synchronization during Cooperative Jenga Game with Face-to-Face Communication.

Functional near-infrared spectroscopy (fNIRS) is an increasingly popular technology for studying social cognition. In particular, fNIRS permits simultaneous measurement of hemodynamic activity in two or more individuals interacting in a naturalistic setting. Here, we used fNIRS hyperscanning to study social cognition and communication in human dyads engaged in cooperative and obstructive interaction while they played the game of Jenga™. Novel methods were developed to identify synchronized channels for each dyad and a structural node-based spatial registration approach was utilized for inter-dyad analyses. Strong inter-brain neural synchrony (INS) was observed in the posterior region of the right middle and superior frontal gyrus, in particular Brodmann area 8 (BA8), during cooperative and obstructive interaction. This synchrony was not observed during the parallel game play condition and the dialog section, suggesting that BA8 was involved in goal-oriented social interaction such as complex interactive movements and social decision-making. INS was also observed in the dorsomedial prefrontal cortex (dmPFC), in particular Brodmann 9, during cooperative interaction only. These additional findings suggest that BA9 may be particularly engaged when theory-of-mind (ToM) is required for cooperative social interaction. The new methods described here have the potential to significantly extend fNIRS applications to social cognitive research.
