Temporal development in the impacts of plant invasions: search for the underlying mechanisms
Authors: Dostál Petr
Published: March 2024

Many invasive plants have negative impacts on native populations and communities, but there remains much uncertainty about how these impacts develop over time. In this review, I describe the mechanisms that promote the initial dominance of invaders, the characteristics associated with large negative impacts, and present the processes that contribute to changes in invader abundance and impacts over time. Together with ecological processes such as ecosystem engineering or enemy accumulation, I show that temporal variation in impacts can be linked to evolution in both native and invasive species. I also show that multiple processes operating in the same invasion system can jointly shape long-term impacts. Finally, I present the framework of modern coexistence theory as a tool for predicting the effects of invaders on native populations, and how these effects change with processes ongoing within invaded communities.

Published: April 2024

Radiological investigations are essential for evaluating underlying structural abnormalities in patients presenting with non-arthritic hip pain. The aim of this study is to quantify the radiation exposure associated with common radiological investigations performed in assessing patients presenting with non-arthritic hip pain. A retrospective review of our institutional imaging database was performed. Data were obtained for antero-posterior, cross-table lateral, frog lateral radiographs and low-dose CT hip protocol. The radiation dose of each imaging technique was measured in terms of dose-area product with units of mGy cm2, and the effective doses (ED, mSv) calculated. The effective radiation dose for each individual hip radiograph performed was in the range of 0.03–0.83 mSv [mean dose-area product 126.7–156.2 mGy cm2]. The mean ED associated with the low-dose CT hip protocol (including assessment of femoral anteversion and tibial torsion) was 3.04 mSv (416.8 mGy cm2). The radiation dose associated with the use of CT imaging was significantly greater than plain radiographs (P < 0.005). Investigation of non-arthritic hip pain can lead to significant ionizing radiation exposure for patients. In our institution, the routine protocol is to obtain an antero-posterior pelvic radiograph and then a specific hip sequence Magnetic Resonance Imaging (MRI) scan which includes the assessment of femoral anteversion. This provides the necessary information in the majority of cases, with CT scanning reserved for more complex cases where we feel there is a specific indication. We would encourage the hip preservation community to carefully consider and review the use of ionizing radiation investigations.
A new measure of US public agency policy discretion
Authors: Smith Natalie L , Yackee Susan Webb
Published: April 2024

The US bureaucracy routinely issues major public policy decisions that affect Americans’ lives. Government agency leaders make those decisions based on a subjective understanding of their agency’s available policy discretion. Over time, discretion has become a prominent theoretical construct in the bureaucratic politics and public administration literature, but it is rarely measured directly. In this article, we create a new measure of agency policy discretion. We draw on research suggesting that discretion is derived from the bureaucracy’s key political principals: the elected executive, legislators, and interest groups. We use data from the American State Administrators Project and trigonometry to calculate the discretion area scores for 8,955 state agencies between 1978 and 2018. We then evaluate the measure through a series of construct validation assessments. The article offers an innovative and generalizable way to operationalize discretion that will advance future scholarship in organizational behavior, public administration, and bureaucratic decision-making.

Published: April 2024

Glioblastoma (GBM) is the most common primary brain cancer, comprising half of all malignant brain tumors. Patients with GBM have a poor prognosis, with a median survival of 14–15 months. Current therapies for GBM, including chemotherapy, radiotherapy, and surgical resection, remain inadequate. Novel therapies are required to extend patient survival. Although immunotherapy has shown promise in other cancers, including melanoma and non-small lung cancer, its efficacy in GBM has been limited to subsets of patients. Identifying biomarkers of immunotherapy response in GBM could help stratify patients, identify new therapeutic targets, and develop more effective treatments. This article reviews existing and emerging biomarkers of clinical response to immunotherapy in GBM. The scope of this review includes immune checkpoint inhibitor and antitumoral vaccination approaches, summarizing the variety of molecular, cellular, and computational methodologies that have been explored in the setting of anti-GBM immunotherapies.
Dual MPO/PR3 ANCA positivity and vasculitis: insights from a 7-cases study and an AI-powered literature review
Authors: Bettacchioli Eléonore , Foulquier Jean-Baptiste , Chevet Baptiste , Cornec-Le Gall Emilie , Hanrotel Catherine , Lanfranco Luca , de Moreuil Claire , Lambert Yannick , Dueymes Maryvonne , Foulquier Nathan , Cornec Divi
Published: March 2024

Objectives

Anti-neutrophil cytoplasm antibodies (ANCA)-associated vasculitides (AAV) are rare conditions characterized by inflammatory cell infiltration in small blood vessels, leading to tissue necrosis. While most patients with AAV present antibodies against either myeloperoxidase (MPO) or proteinase 3 (PR3), rare cases of dual positivity for both antibodies (DP-ANCA) have been reported, and their impact on the clinical picture remains unclear. The goal of this study was to investigate the clinical implications, phenotypic profiles and outcomes of patients with DP-ANCA.

Methods

A retrospective screening for DP-ANCA cases was conducted at Brest University Hospital's immunology laboratory (France), analysing ANCA results from March 2013 to March 2022. Clinical, biological, imaging, and histological data were collected for each DP-ANCA case. Additionally, a comprehensive literature review on DP-ANCA was performed, combining an artificial intelligence (AI)-based search using BIBOT software with a manual PUBMED database search.

Results

The report of our cases over the last 9 years and those from the literature yielded 103 described cases of patients with DP-ANCA. We identified four distinct phenotypic profiles: (i) idiopathic AAV (∼30%); (ii) drug-induced AAV (∼25%); (iii) autoimmune disease associated with a low risk of developing vasculitis (∼20%); and (iv) immune-disrupting comorbidities (infections, cancers, etc) not associated with AAV (∼25%).

Conclusion

This analysis of over a hundred DP-ANCA cases suggests substantial diversity in clinical and immunopathological presentations. Approximatively 50% of DP-ANCA patients develop AAV, either as drug-induced or idiopathic forms, while the remaining 50%, characterized by pre-existing dysimmune conditions, demonstrates a remarkably low vasculitis risk. These findings underscore the complex nature of DP-ANCA, its variable impact on patient health, and the necessity for personalized diagnostic and management approaches in these cases.

Published: March 2024

Objective

Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome is a complex immune disorder consequence of somatic UBA1 variants. Most reported pathogenic UBA1 variants are missense or splice site mutations directly impairing the translational start site at p.Met41, with recent studies showing that these variants are frequent causes of recurrent inflammation in older individuals. Here we aimed to characterize a novel UBA1 variant found in two patients clinically presenting with VEXAS syndrome.

Methods

Patients’ data were collected from direct assessments and from their medical charts. Genomics analyses were undertaken by both Sanger and amplicon-based deep sequencing, and mRNA studies were undertaken by both cDNA subcloning and mRNA sequencing.

Results

We report a novel, somatic variant in a canonical splice site of the UBA1 gene (c.346-2A>G), which was identified in two unrelated adult male patients with late-onset, unexplained inflammatory manifestations including recurrent fever, Sweet syndrome-like neutrophilic dermatosis, and lung inflammation responsive only to glucocorticoids. RNA analysis of the patients’ samples indicated aberrant mRNA splicing leading to multiple in-frame transcripts, including a transcript retaining the full sequence of intron 4 and a different transcript with the deletion of the first 15 nucleotides of exon 5.

Conclusion

Here we describe abnormal UBA1 transcription as a consequence of the novel c.346-2A>G variant, identified in two patients with clinical features compatible with VEXAS syndrome. Overall, these results further demonstrate the expanding spectrum of variants in UBA1 leading to pathology and provide support for a complete gene evaluation in those patients considered candidates for VEXAS syndrome.
Influence of Substrate Stiffness on iPSC-Derived Retinal Pigmented Epithelial Cells
Authors: Wendland Rion J , Tucker Budd A , Worthington Kristan S
Published: April 2024

Retinal degenerative diseases are a major cause of blindness involving the dysfunction of photoreceptors, retinal pigmented epithelium (RPE), or both. A promising treatment approach involves replacing these cells via surgical transplantation, and previous work has shown that cell delivery scaffolds are vital to ensure sufficient cell survival. Thus, identifying scaffold properties that are conducive to cell viability and maturation (such as suitable material and mechanical properties) is critical to ensuring a successful treatment approach. In this study, we investigated the effect of scaffold stiffness on human RPE attachment, survival, and differentiation, comparing immortalized (ARPE-19) and stem cell-derived RPE (iRPE) cells. Polydimethylsiloxane was used as a model polymer substrate, and varying stiffness (~12 to 800 kPa) was achieved by modulating the cross-link-to-base ratio. Post-attachment changes in gene and protein expression were assessed using qPCR and immunocytochemistry. We found that while ARPE-19 and iRPE exhibited significant differences in morphology and expression of RPE markers, substrate stiffness did not have a substantial impact on cell growth or maturation for either cell type. These results highlight the differences in expression between immortalized and iPSC-derived RPE cells, and also suggest that stiffnesses in this range (~12-800 kPa) may not result in significant differences in RPE growth and maturation, an important consideration in scaffold design.
Systems-Based Practice: Expert Perspectives on the Origin and Evolution of an Ambiguous Competency
Authors: DeWaters Ami L. , Miller Erin L. , Haidet Paul , Gonzalo Jed D.
Published: April 2024

Purpose

Systems-based practice (SBP) has been a core competency in graduate medical education in the United States since 1999, but it has been difficult to operationalize in residency programs due to its conceptual ambiguity. The authors explored the historical origin and subsequent development of the SBP competency from the perspective of individuals who were influential across critical phases of its implementation and ensuing development. The goal of this study was to elicit the history of SBP from the perspective of individuals who have expertise in it and to use those findings to inform the current SBP construct.

Method

Between March and July 2021, 24 physicians, nurses, educators, and leaders in the field of SBP were individually interviewed about the origin and meaning of SBP as practiced in U.S. medical education using a semistructured guide. Individuals were selected based upon their influence on the origin or evolution of the SBP competency. Data were iteratively collected and analyzed using real-time analytic memos, regular adjudication sessions with the research team, and thematic analysis. Researchers identified themes from participants’ perspectives and agreed upon the final results and quotations.

Results

Five themes were identified: SBP has many different definitions, SBP was intentionally designed to be vague, systems thinking was identified as the foundation of the SBP competency, the 6 core competencies established in the United States by the Accreditation Council for Graduate Medical Education were developed to be interdependent, and the SBP and practice-based learning and improvement competencies are uniquely related and synergistic.

Conclusions

Interview data indicate that since its inception, SBP has been a nuanced and complex competency, resulting in a lack of mutually shared understanding among stakeholders. This deliberate historical examination of expert perspectives provides insight into specific areas for improving how SBP is taught and learned.

The Relationship Between Program and Applicant Characteristics With Applicant Program Signals in the 2022 Residency Recruitment Cycle: Findings From 3 Specialties
Authors: LaFemina Jennifer , Rosman Ilana S. , Wallach Sara L. , Wise Paul E. , Smink Douglas S. , Fletcher Laura
Published: April 2024

Purpose

Continuing increases in application volume have driven a national dialogue to reform the residency recruitment process. Program signaling allows applicants to express interest in a program at the preinterview stage with the goal of helping programs identify applicants with more genuine interest in their programs. This study explored the relationship between program signals and program and applicant characteristics.

Method

Participating dermatology, general surgery, and categorical internal medicine (IM) programs and applicants of the 2022 supplemental ERAS application (SuppApp) were included. Data from the SuppApp, the MyERAS Application for Residency Applicants (MyERAS), and the 2020 GME Track Survey were used. Cohen’s h was used to determine effect size, and chi-squared was used to determine statistical significance.

Results

There was an uneven distribution of signals to programs, with 25% of programs receiving about half of the signals across all 3 specialties. Programs with larger numbers of both residents and applicants received greater numbers of program signals relative to their program density, although this effect was small (h < 0.50, P < .001). No meaningful differences were seen across genders for any specialty. Only Hispanic applicants in IM sent a higher proportion of signals to programs with more underrepresented in medicine residents than White only applicants (40% vs 26%, h = 0.30, P < .001). Across all specialties, there was a small-to-moderate effect for international medical graduate (IMG) applicants sending a larger proportion of signals to programs with more IMG residents (h < 0.80, P < .001).

Conclusions

This first-year pilot study (i.e., SuppApp) provided initial evidence that supports the feasibility and fairness of program signals in residency selection. As program signals become more common across specialties, future research should continue to evaluate trends in where applicants send signals, and possible relationships between program and application characteristics.
Teaching Trainees Effective Patient Communication Skills in the Clinical Environment: Best Practices Under Crisis Conditions
Authors: Dubosh Nicole M. , Carter Keme
Published: April 2024

Communication within the health care setting has significant implications for the safety, engagement, and well-being of patients and physicians. Evidence shows that communication training is variable or lacking in undergraduate and graduate medical education. Physician-patient communication presents a vulnerable point in patient care, which was heightened by the COVID-19 pandemic and its aftermath. Physicians have to adapt their strategies to meet new challenges, including communicating through the necessary barriers of personal protective equipment and telecommunication platforms. They also face uncharted challenges of facilitating discussions around proactive planning and scarce resources. Medical educators must be equipped to provide trainees with the skills needed to maintain empathy, facilitate trust and connection, and adapt communication behaviors under such crisis conditions. Using the Calgary-Cambridge model as a framework, the authors describe 3 new challenges to effective physician-patient communication for which COVID-19 was the impetus—face masks, visitor restrictions, and resource allocation/proactive planning discussions—and propose educational solutions.
Abortion Care After the Dobbs Decision: An Academic Health System’s Response to a Statewide Ban
Authors: Larin Katherine Q. , Rouse Caroline E. , Bernard Caitlin , Castor Tory Callaghan , Kremer Brian , Ingram David A.
Published: April 2024

Indiana was the first state to pass legislation severely restricting access to abortion care following the Dobbs v. Jackson Women’s Health Organization decision. Indiana Senate Enrolled Act 1 (SEA 1) outlaws all abortions with few exceptions. Indiana University Health (IU Health), the largest and only academic health system in the state, has a unique relationship with the Indiana University School of Medicine and a vision to improve the health of Indiana residents. IU Health employed the Hospital Incident Command System model to create a plan to ensure its patients continue to have access to safe, high-quality family planning, maternal, and neonatal care services and that clinicians are protected against criminal penalties and threats to personal safety. This article provides an overview of the Incident Command structure used to rapidly work across many disciplines, tackle complex issues, respond to concerns, and design and implement changes. The article also outlines the key considerations and decisions made by Incident Command leaders, such as where abortions that met the new law’s criteria should be performed, changes to clinical workflows and protocols, and the creation of a rapid response team. The article then examines the operational, legal, and clinical challenges encountered by clinicians and health care team members, including a lack of peer support or idea sharing with other health systems in the state; accurate estimation of abortion, live birth, and neonatal intensive care unit volumes; and ambiguity in the law and lack of guidance from the state government. Recommendations regarding communication with clinicians and other health care team members and engaging information technology early are offered for health systems and medical schools that may face legislative barriers to health care delivery in the future. Finally, IU Health’s commitment to tracking the impact of SEA 1 on patients, clinicians, employees, and the state is outlined.
Systems-Based Practice 20 Years On: Navigating the System for Better Care
Authors: Edgar Laura , Hogan Sean O. , Yamazaki Kenji , Nasca Thomas J. , Holmboe Eric S.
Published: April 2024

Systems-based practice (SBP) was introduced as 1 of 6 core competencies in 1999 because of its recognized importance in the quality and safety of health care provided to patients. Nearly 25 years later, faculty and learners continue to struggle with understanding and implementing this essential competency, thus hindering the medical education community’s ability to most effectively teach and learn this important competency.

Milestones were first introduced in 2013 as one effort to support implementation of the general competencies. However, each specialty developed its milestones independently, leading to substantial heterogeneity in the narrative descriptions of competencies including SBP. The process to create Milestones 2.0, and more specifically, the Harmonized Milestones, took this experience into account and endeavored to create a shared language for SBP across all specialties and subspecialties. The 3 subcompetencies in SBP are now patient safety and quality improvement, systems navigation for patient-centered care (coordination of care, transitions of care, local population health), and physician’s role in health care systems (components of the system, costs and resources, transitions to practice). Milestones 2.0 are also now supported by new supplemental guides that provide specific real-world examples to help learners and faculty put SBP into the context of the complex health care environment.

While substantially more resources and tools are now available to aid faculty and to serve as a guide for residents and fellows, much work to effectively implement SBP remains. This commentary will explore the evolutionary history of SBP, the challenges facing implementation, and suggestions for how programs can use the new milestone resources for SBP. The academic medicine community must work together to advance this competency as an essential part of professional development.
Comparison of Differences in Cohort (Forward) and Case Control (Backward) Methodologic Approaches for Validation of the Hypotension Prediction Index

Published: April 2024

Background

The Hypotension Prediction Index (the index) software is a machine learning algorithm that detects physiologic changes that may lead to hypotension. The original validation used a case control (backward) analysis that has been suggested to be biased. This study therefore conducted a cohort (forward) analysis and compared this to the original validation technique.

Methods

A retrospective analysis of data from previously reported studies was conducted. All data were analyzed identically with two different methodologies, and receiver operating characteristic curves were constructed. Both backward and forward analyses were performed to examine differences in area under the receiver operating characteristic curves for the Hypotension Prediction Index and other hemodynamic variables to predict a mean arterial pressure (MAP) less than 65 mmHg for at least 1 min 5, 10, and 15 min in advance.

Results

The analysis included 2,022 patients, yielding 4,152,124 measurements taken at 20-s intervals. The area under the curve for the index predicting hypotension analyzed by backward and forward methodologies respectively was 0.957 (95% CI, 0.947 to 0.964) versus 0.923 (95% CI, 0.912 to 0.933) 5 min in advance, 0.933 (95% CI, 0.924 to 0.942) versus 0.923 (95% CI, 0.911 to 0.933) 10 min in advance, and 0.929 (95% CI, 0.918 to 0.938) versus 0.926 (95% CI, 0.914 to 0.937) 15 min in advance. No variable other than MAP had an area under the curve greater than 0.7. The areas under the curve using forward analysis for MAP predicting hypotension 5, 10, and 15 min in advance were 0.932 (95% CI, 0.920 to 0.940), 0.929 (95% CI, 0.918 to 0.938), and 0.932 (95% CI, 0.921 to 0.940), respectively. The R
2 for the variation in the index due to MAP was 0.77.

Conclusions

Using an updated methodology, the study found that the utility of the Hypotension Prediction Index to predict future hypotensive events is high, with an area under the receiver operating characteristics curve similar to that of the original validation method.

Association between Preoperative Blood Pressures and Postoperative Adverse Events
Authors: Walco Jeremy P. , Rengel Kimberly F. , McEvoy Matthew D. , Henson C. Patrick , Li Gen , Shotwell Matthew S. , Feng Xiaoke , Freundlich Robert E.
Published: April 2024

Background

The relationship between postoperative adverse events and blood pressures in the preoperative period remains poorly understood. This study tested the hypothesis that day-of-surgery preoperative blood pressures are associated with postoperative adverse events.

Methods

The authors conducted a retrospective, observational study of adult patients having elective procedures requiring an inpatient stay between November 2017 and July 2021 at Vanderbilt University Medical Center to examine the independent associations between preoperative systolic and diastolic blood pressures (SBP, DBP) recorded immediately before anesthesia care and number of postoperative adverse events—myocardial injury, stroke, acute kidney injury, and mortality—while adjusting for potential confounders. The study used multivariable ordinal logistic regression to model the relationship.

Results

The analysis included 57,389 cases. The overall incidence of myocardial injury, stroke, acute kidney injury, and mortality within 30 days of surgery was 3.4% (1,967 events), 0.4% (223), 10.2% (5,871), and 2.1% (1,223), respectively. The independent associations between both SBP and DBP measurements and number of postoperative adverse events were found to be U-shaped, with greater risk both above and less than SBP 143 mmHg and DBP 86 mmHg—the troughs of the curves. The associations were strongest at SBP 173 mmHg (adjusted odds ratio, 1.212 vs. 143 mmHg; 95% CI, 1.021 to 1.439; P = 0.028), SBP 93 mmHg (adjusted odds ratio, 1.339 vs. 143 mmHg; 95% CI, 1.211 to 1.479; P < 0.001), DBP 106 mmHg (adjusted odds ratio, 1.294 vs. 86 mmHg; 95% CI, 1.003 to 1.17671; P = 0.048), and DBP 46 mmHg (adjusted odds ratio, 1.399 vs. 86 mmHg; 95% CI, 1.244 to 1.558; P < 0.001).

Conclusions

Preoperative blood pressures both less than and above a specific threshold were independently associated with a higher number of postoperative adverse events, but the data do not support specific strategies for managing patients with low or high blood pressure on the day of surgery.

Midlife Speech Perception Deficits: Impact of Extended High-Frequency Hearing, Peripheral Neural Function, and Cognitive Abilities
Authors: Patro Chhayakanta , Monfiletto Angela , Singer Aviya , Srinivasan Nirmal Kumar , Mishra Srikanta Kumar
Published: April 2024

Objectives:

The objectives of the present study were to investigate the effects of age-related changes in extended high-frequency (EHF) hearing, peripheral neural function, working memory, and executive function on speech perception deficits in middle-aged individuals with clinically normal hearing.

Design:

We administered a comprehensive assessment battery to 37 participants spanning the age range of 20 to 56 years. This battery encompassed various evaluations, including standard and EHF pure-tone audiometry, ranging from 0.25 to 16 kHz. In addition, we conducted auditory brainstem response assessments with varying stimulation rates and levels, a spatial release from masking (SRM) task, and cognitive evaluations that involved the Trail Making test (TMT) for assessing executive function and the Abbreviated Reading Span test (ARST) for measuring working memory.

Results:

The results indicated a decline in hearing sensitivities at EHFs and an increase in completion times for the TMT with age. In addition, as age increased, there was a corresponding decrease in the amount of SRM. The declines in SRM were associated with age-related declines in hearing sensitivity at EHFs and TMT performance. While we observed an age-related decline in wave I responses, this decline was primarily driven by age-related reductions in EHF thresholds. In addition, the results obtained using the ARST did not show an age-related decline. Neither the auditory brainstem response results nor ARST scores were correlated with the amount of SRM.

Conclusions:

These findings suggest that speech perception deficits in middle age are primarily linked to declines in EHF hearing and executive function, rather than cochlear synaptopathy or working memory.
ICU Care Team’s Perception of Clinical Research in the ICU: A Cross-Sectional Study
Authors: Krewulak Karla , Ogunyannwo Toyin , Martin Dori-Ann , Ruddell Stacy , Yasmeen Israt , Fiest Kirsten
Published: April 2024

OBJECTIVES:

Adequate recruitment is essential for successful clinical research. ICU nurses play a crucial role in identifying eligible patients, introducing research teams, facilitating informed consent, and caring for enrolled patients. However, a larger group of multidisciplinary healthcare professionals (the ICU care team) is equally important in promoting clinical research participation.

To describe the ICU care team’s experiences in ongoing clinical research, identifying perceived barriers and enablers to their participation, and apply a behavior framework to enhance research engagement.

DESIGN:

Cross-sectional survey study.

SETTING:

Four adult ICUs and one PICU between June 2021 and March 2023.

SUBJECTS:

We recruited nurses, physicians, nurse practitioners, allied health professionals, and unit clerks.

MEASUREMENT AND MAIN RESULTS:

We developed and validated a cross-sectional survey based on the Capability, Opportunity, Motivation, Behavior model. This survey included: 1) demographic questions (n = 7); 2) research experience questions (n = 6), 3) capability questions (n = 8); 4) opportunity questions (n = 11); 5) and motivation questions (n = 13).

A total of 172 ICU care team members completed the survey. Results showed differences in capabilities, opportunities, and motivations among ICU care team members. For example, fellow/attending physicians and nurse practitioners reported higher confidence in discussing research with patients/families, while registered nurses and allied health professionals expressed less confidence.

CONCLUSIONS:

ICU care team members face multiple barriers that impact their involvement with the conduct of ICU research. To effectively engage healthcare professionals in this process, it is essential to address their capabilities (research knowledge and skills to communicate research with patients/families), create opportunities (collaboration/communication with research team, discuss research during multidisciplinary rounds), and motivate them (recognize their help and share the results of the research being conducted at their site) to improve ICU care team engagement in the conduct of ICU research.
Environmental Comfort in Promoting Sleep in Critically Ill Patients
Authors: Moura Derek Braga , de Fátima Sousa Andrade Débora , Silva Carla Rodrigues , Soares-Pinto Igor Emanuel
Published: April 2024

Introduction

It is important to understand the concept of comfort as a whole to build an assistance intervention plan that meets the person's needs. Therefore, it is necessary to monitor and assess the person's sleep by considering the surrounding environment, to provide a comfortable environment that is quiet and provides privacy, especially in contexts of difficult management of environmental factors in the approach to the person in critical condition.

Objectives

The aims of this study were to map the nursing interventions that promote sleep-promoting environmental comfort in critically ill people and identify the instruments to assess sleep in critically ill people.

Methods

This is a scoping review based on the methodological strategy of the Joanna Briggs Institute for Scoping Reviews. The search was conducted on February 17 and 18, 2022, in the databases CINAHL, Cochrane Library Plus, PubMed, JBI Evidence Synthesis, SciELO, DANS Easy Archive, RCAAP, and DART-Europe using the Boolean phrase search strategy: “Hospital Emergency Service” OR “Critical Care” AND “Sleep” NOT “Children” AND Nurs*. We included all studies, conducted in any contextual setting, in Portuguese, English, or Spanish, on adult patients with acute and/or critical illness in intensive care and/or emergency units, which addressed nursing interventions that contribute to environmental comfort and promote sleep. Studies on pregnant or puerperal women, persons with psychiatric disorders, and those at the end of life or in palliative care were excluded.

Results

Twenty-one articles were included in this scoping review. Three categories of nursing interventions emerged: person centered (14 interventions), environment centered (37 interventions), and nurse role centered (45 interventions). Three categories of instruments for sleep assessment emerged, in particular: quality of sleep (12 instruments), environmental effects on a night's sleep (2 instruments), and influence on sleep practices in the intensive care unit (1 instrument).

Discussion

The use of instruments to monitor comfort and sleep allows for an accurate assessment of the impact of nurses' intervention focusing on sleep-promoting interventions aimed at comfort, for an improvement of sleep in critically ill patients.

Conclusion

The interpretation of the content makes it clear that how critically ill patients in different contexts experience the environmental context positively or negatively conditions their comfort. In this sense, it is essential to reflect on these measures as a team so that everyone can apply them.
Evaluation of Delirium Among Elders in the Emergency Department
Authors: Marcomini Ilaria , Pisoni Luca , Mellino Antonio , Labaran Raisa , Milani Laura
Published: April 2024

Background

Health care professionals underestimate the recognition of delirium in emergency departments (EDs). In these settings, between 57% and 83% of cases of delirium go undetected. When delirium occurs, it causes an increase in the length of hospitalization, readmissions within 30 days, and mortality. No studies were carried out in Italy to assess the prevalence of delirium among elders in EDs.

Objectives

The primary goal of the study was to evaluate the prevalence of the risk of delirium in people 65 years and older hospitalized in the ED for a minimum of 8 hours. The study's secondary goal was to identify the variables that influenced the risk of delirium.

Method

A multicenter cross-sectional study was conducted in 2 EDs. The risk of delirium was assessed using the delirium screening tool 4 A's test. One hundred patients were enrolled. Data collection took place from June 28 to August 31, 2022.

Results

The risk of delirium was detected in 29% of the sample, whereas the risk of cognitive impairment was 13%. The use of psychotropic drugs increased the risk of delirium by 11.8 times (odds ratio [OR], 11.80; P = .003). Bed confinement increased the risk by 4.3 times (OR, 4.31; P = .009). Being dehydrated increased the risk of onset by 4.6 times (OR, 4.62; P = .010). Having dementia increased the risk of delirium manifestation by 4.4 times (OR, 4.35; P = .021).

Discussion

The risk of delirium was detected in a considerable portion of the sample. The results of this study can be used by health care professionals to implement preventive measures as well as support clinical judgment and establish priorities of care for patients at risk of developing delirium.

Brexanolone is approved for postpartum depression (PPD) by the United States Food and Drug Administration. Brexanolone has outperformed placebo in clinical trials, but less is known about the efficacy in real-world patients with complex social and medical histories. Furthermore, the impact of brexanolone on large-scale brain systems such as changes in functional connectivity (FC) is unknown.

Methods/Procedures

We tracked changes in depressive symptoms across a diverse group of patients who received brexanolone at a large medical center. Edinburgh Postnatal Depression Scale (EPDS) scores were collected through chart review for 17 patients immediately prior to infusion through approximately 1 year postinfusion. In 2 participants, we performed precision functional neuroimaging (pfMRI), including before and after treatment in 1 patient. pfMRI collects many hours of data in individuals for precision medicine applications and was performed to assess the feasibility of investigating changes in FC with brexanolone.

Findings/Results

The mean EPDS score immediately postinfusion was significantly lower than the mean preinfusion score (mean change [95% CI]: 10.76 [7.11–14.40], t(15) = 6.29, P < 0.0001). The mean EPDS score stayed significantly lower at 1 week (mean difference [95% CI]: 9.50 [5.23–13.76], t(11) = 4.90, P = 0.0005) and 3 months (mean difference [95% CI]: 9.99 [4.71–15.27], t(6) = 4.63, P = 0.0036) postinfusion. Widespread changes in FC followed infusion, which correlated with EPDS scores.

Implications/Conclusions

Brexanolone is a successful treatment for PPD in the clinical setting. In conjunction with routine clinical care, brexanolone was linked to a reduction in symptoms lasting at least 3 months. pfMRI is feasible in postpartum patients receiving brexanolone and has the potential to elucidate individual-specific mechanisms of action.

Background

Presentations are an important means of knowledge generation. Publication of these studies is important for dissemination of findings beyond meeting attendees. We analyzed a 10-year sample of presented abstracts at Plastic Surgery The Meeting and describe factors that improve rate and speed of conversion to peer-reviewed publication.

Methods

Abstracts presented between 2010 and 2019 at Plastic Surgery The Meeting were sourced from the American Society of Plastic Surgery Abstract Archive. A random sample of 100 abstracts from each year was evaluated. Abstract information and demographics were recorded. The title or author and keywords of each abstract were searched using a standardized workflow to find a corresponding published paper on PubMed, Google Scholar, and Google. Data were analyzed for trends and factors affecting conversion rate.

Results

A total of 983 presented abstracts were included. The conversion rate was 54.1%. Residents and fellows constituted the largest proportion of presenters (38.4%). There was a significant increase in medical student and research fellow presenters during the study period (P < 0.001). Conversion rate was not affected by the research rank of a presenter's affiliated institution (β = 1.001, P = 0.89), geographic location (P = 0.60), or subspecialty tract (P = 0.73). US academics had a higher conversion rate (61.8%) than US nonacademics (32.7%) or international presenters (47.1%) (P < 0.001). Medical students had the highest conversion rate (65.6%); attendings had the lowest (45.0%). Research fellows had the lowest average time to publication (11.6 months, P = 0.007).

Conclusions

Lower levels of training, factors associated with increased institution-level support, and research quality affect rate and time to publication. These findings highlight the success of current models featuring medical student and research fellow-led projects with strong resident and faculty mentorship.
Simultaneous Free Flap Breast Reconstruction Combined With Contralateral Mastopexy or Breast Reduction

Published: April 2024

Background

Simultaneous free flap breast reconstruction combined with contralateral mastopexy or breast reduction can increase patient satisfaction and minimize the need for a second procedure. Surgeon concerns of increases in operative time, postoperative complications, and final breast symmetry may decrease the likelihood of these procedures being done concurrently. This study analyzed postoperative outcomes of simultaneous contralateral mastopexy or breast reduction with free flap breast reconstruction.

Methods

By using the American College of Surgeons National Surgical Quality Improvement Program database (2010–2020), we analyzed 2 patient cohorts undergoing (A) free flap breast reconstruction only and (B) free flap breast reconstruction combined with contralateral mastopexy or breast reduction. The preoperative variables assessed included demographic data, comorbidities, and perioperative data. Using a neighbor matching algorithm, we performed a 1:1 propensity score matching of 602 free flap breast reconstruction patients and 621 with concurrent contralateral operation patients. Bivariate analysis for postoperative surgical and medical complications was performed for outcomes in the propensity-matched cohort.

Results

We identified 11,308 cases who underwent microsurgical free flap breast reconstruction from the American College of Surgeons National Surgical Quality Improvement Program database from the beginning of 2010 to the end of 2020. A total of 621 patients underwent a free flap breast reconstruction combined with contralateral mastopexy or breast reduction. After propensity score matching, there were no significant differences in patient characteristics, perioperative variables or postoperative medical complications between the 2 cohorts.

Conclusions

Simultaneous free flap breast reconstruction combined with contralateral mastopexy or breast reduction can be performed safely and effectively without an increase in postoperative complication rates. This can improve surgeon competence in offering this combination of procedures as an option to breast cancer survivors, leading to better patient outcomes in terms of symmetrical and aesthetically pleasing results, reduced costs, and elimination of the need for a second operation.
Parental Education for the Prevention of Plagiocephaly

Published: April 2024

Introduction

The American Academy of Pediatrics Back-to-Sleep Campaign significantly reduced infant mortality from sudden infant death syndrome. As a result of prolonged supine positioning, the incidence of deformational plagiocephaly has also risen 5-fold since its adoption. We aimed to improve the current educational paradigm for new parents with the goal of reducing the incidence of plagiocephaly within the confines of the Back-to-Sleep Campaign. We hypothesized that the early addition of plagiocephaly focused education for parents would reduce cephalic index, the ratio of head width to length, used as an easily measured objective proxy for positional plagiocephaly.

Methods

Children were screened at their newborn visit. Premature newborns and those diagnosed with craniofacial disorders were excluded. For those enrolled, biparietal and anteroposterior measurements of the head were obtained using manual calipers to obtain cephalic index. Subjects randomly assigned to the intervention group were shown a 2-minute video and given an educational pamphlet on methods to prevent plagiocephaly. Unpaired 2-sample t tests comparing mean differences in intervention and control were performed.

Results

Thirty-nine subjects were enrolled as of November 2023 with variable lengths of follow-up completed. The average baseline cephalic index for subjects in the control group was 82.7 and 83.8 for intervention group. Unpaired 2-sample t tests were performed at 2-, 4-, and 6-month time points to analyze the difference between groups. At 4 months, average cephalic index for subjects in the control and treatment group, respectively, was 90.6 and 83.4 (P = 0.02).

Significance

Parental education at the newborn visit led to decreases in cephalic index, a proxy for positional plagiocephaly, compared with control patients. This simple intervention has the potential to reduce parental stress and healthcare costs associated with the evaluation and treatment of plagiocephaly.

Introduction

Disparities in postmastectomy reconstructive care are widely acknowledged. However, there is limited understanding regarding the impact of reconstructive services on cancer recurrence and breast cancer–related mortality. Therefore, this study aims to examine how patient-specific factors and breast reconstruction status influence recurrence-free survival and mortality rates in breast cancer patients.

Methods

Retrospective chart review was performed to collect data on patients who underwent mastectomy at 2 institutions within the New York-Presbyterian system from 1979 to 2019. Sociodemographic information, medical history, and the treatment approach were recorded. Propensity score matching, logistic regression, unpaired t test, and chi-square test were used for statistical analysis.

Results

Overall, cancer recurrence occurred in 6.62% (317) of patients, with 16.8% (803) overall mortality rate. For patients who had relapsed disease, completion of the reconstruction sequence was correlated with an earlier detection of cancer recurrence and improved survival odds (P < 0.05). Stratified analysis of the reconstruction group alone showed mortality benefit among patients who underwent free flap procedures (P < 0.05).

Conclusion

Patients undergoing breast reconstruction after mastectomy are likely to have better access to follow-up care and improved interfacing with the healthcare system. This may increase the speed at which cancer recurrence is detected. This study highlights the need for consistent plastic surgery referral and continued monitoring by all members of the breast cancer care team for cancer recurrence among patients.
