Significance of isolated postoperative atrial fibrillation in thoracic aortic aneurysm repair.

OBJECTIVE: Although postoperative atrial fibrillation has been shown to be associated with worse survival after thoracic aortic surgery, its effect on outcomes independently from other postoperative complications is not well understood. METHODS: This is a single-center retrospective study of patients who underwent open thoracic aortic aneurysm repair between March 2005 and March 2021. Postoperative atrial fibrillation was defined as new-onset atrial fibrillation that developed during the index hospital stay. Patients with preoperative atrial fibrillation were excluded. Postoperative major complications included reoperation for bleeding, respiratory failure, acute renal failure, and stroke. Variables associated with postoperative atrial fibrillation were analyzed with multivariable regression. Survival of patients without major complications was compared between patients without atrial fibrillation and patients with postoperative atrial fibrillation after propensity score matching for baseline and intraoperative characteristics. RESULTS: Of 1454 patients, 520 (35.8%) were observed to have postoperative atrial fibrillation. Patients with postoperative atrial fibrillation had a higher rate of postoperative major complications than those without atrial fibrillation (20.2% vs 12.2%, P < .001). Ten-year survival was 82.0% in patients with postoperative atrial fibrillation and 87.0% in patients without atrial fibrillation (P = .008). In the cohort of patients without complications, 10-year survival was similar between patients with and without postoperative atrial fibrillation after propensity score matching (83.6% vs 83.8%, P = .75). CONCLUSIONS: Postoperative atrial fibrillation is common after open proximal thoracic aortic aneurysm repair. Although development of major postoperative complications is associated with postoperative atrial fibrillation and decreased long-term survival, isolated postoperative atrial fibrillation does not appear to influence long-term survival.

Effectiveness of laparoscopic removal of isolated superficial peritoneal endometriosis for the management of chronic pelvic pain in women (ESPriT2): protocol for a multi-centre randomised controlled trial.

BACKGROUND: Endometriosis affects 190 million women and those assigned female at birth worldwide. For some, it is associated with debilitating chronic pelvic pain. Diagnosis of endometriosis is often achieved through diagnostic laparoscopy. However, when isolated superficial peritoneal endometriosis (SPE), the most common endometriosis subtype, is identified during laparoscopy, limited evidence exists to support the common decision to surgically remove it via excision or ablation. Improved understanding of the impact of surgical removal of isolated SPE for the management of chronic pelvic pain in women is required. Here, we describe our protocol for a multi-centre trial to determine the effectiveness of surgical removal of isolated SPE for the management of endometriosis-associated pain. METHODS: We plan to undertake a multi-centre participant-blind parallel-group randomised controlled clinical and cost-effectiveness trial with internal pilot. We plan to randomise 400 participants from up to 70 National Health Service Hospitals in the UK. Participants with chronic pelvic pain awaiting diagnostic laparoscopy for suspected endometriosis will be consented by the clinical research team. If isolated SPE is identified at laparoscopy, and deep or ovarian endometriosis is not seen, participants will be randomised intraoperatively (1:1) to surgical removal (by excision or ablation or both, according to surgeons' preference) versus diagnostic laparoscopy alone. Randomisation with block-stratification will be used. Participants will be given a diagnosis but will not be informed of the procedure they received until 12 months post-randomisation, unless required. Post-operative medical treatment will be according to participants' preference. Participants will be asked to complete validated pain and quality of life questionnaires at 3, 6 and 12 months after randomisation. Our primary outcome is the pain domain of the Endometriosis Health Profile-30 (EHP-30), via a between randomised group comparison of adjusted means at 12 months. Assuming a standard deviation of 22 points around the pain score, 90% power, 5% significance and 20% missing data, 400 participants are required to be randomised to detect an 8-point pain score difference. DISCUSSION: This trial aims to provide high quality evidence of the clinical and cost-effectiveness of surgical removal of isolated SPE. TRIAL REGISTRATION: ISRCTN registry ISRCTN27244948. Registered 6 April 2021.

Patient choice: the shape of consent post-Montgomery.

The law relating to consent and the process dentists need to go through to gain valid and informed consent to treat patients changed significantly following the landmark ruling of Montgomery v Lanarkshire Health Board. In this paper, we revisit the history of patient consent, give an update on the current legal situation in the UK, and produce a unique 'consent workflow' to aid in the process of gaining valid and informed consent to treat. The aim is to clarify the legal standing and provide a framework that dentists and other healthcare professionals can adapt to their current clinical practice while increasing the confidence of those involved in the consent process; both professionals and patients.

Update on Mechanical Circulatory Support.

Mechanical circulatory support (MCS) devices provide temporary or intermediate- to long-term support for acute cardiopulmonary support. In the last 20 to 30 years, tremendous growth in MCS device usage has been seen. These devices offer support for isolated respiratory failure, isolated cardiac failure, or both. Initiation of MCS devices requires the input from multidisciplinary teams using patient factors and institutional resources to guide decision making, along with a planned "exit strategy" for bridge to decision, bridge to transplant, bridge to recovery, or as destination therapy. Important considerations for MCS use include patient selection, cannulation/insertion strategies, and complications of each device.

Efficacy, Safety, and Strategies for Recombinant-Activated Factor VII in Cardiac Surgical Bleeding: A Narrative Review.

As perioperative bleeding continues to be a major source of morbidity and mortality in cardiac surgery, the search continues for an ideal hemostatic agent for use in this patient population. Transfusion of blood products has been associated both with increased costs and risks, such as infection, prolonged mechanical ventilation, increased length of stay, and decreased survival. Recombinant-activated factor VII (rFVIIa) first was approved for the US market in 1999 and since that time has been used in a variety of clinical settings. This review summarizes the existing literature pertaining to perioperative rFVIIa, in addition to society recommendations and current guidelines regarding its use in cardiac surgery.

Impact of Early, Low-Dose Factor VIIa on Subsequent Transfusions and Length of Stay in Cardiac Surgery.

OBJECTIVE: Recombinant factor VII (rFVIIa) is used to treat cardiac surgical bleeding in an off-label manner. However, optimal dosing and timing of administration to provide efficacious yet safe outcomes remain unknown. DESIGN: Retrospective, observational study. SETTING: Tertiary care academic center. PARTICIPANTS: Cardiac surgical patients (N = 214) who received low-dose rFVIIa for cardiac surgical bleeding. INTERVENTIONS: Patients were allocated into one of three groups based on timing of rFVIIa administration during the course of bleeding resuscitation based on the number of hemostatic products given before rFVIIa administration: group one = ≤one products (n = 82); group two = two-to-four products (n = 73); and group three= ≥five products (n = 59). MEASUREMENTS AND MAIN RESULTS: Patients who received low-dose rFVIIa later in the course of bleeding resuscitation (group three) had longer intensive care unit stays (p = 0.014) and increased incidence of postoperative renal failure when compared with group one (p = 0.039). Total transfusions were lowest in patients who received rFVIIa early in the course of resuscitation (group one) (median, two [interquartile range (IQR), 1-4.75]) and highest in group three (median, 11 [IQR, 8-14]; p < 0.001). Subsequent blood product transfusions after rFVIIa administration were highest in group two (p = 0.003); however, the median for all three groups was two products. There were no differences in thrombosis, reexplorations, or mortality in any of the groups. CONCLUSIONS: This study identified no differences in adverse outcomes based on timing of administration of low-dose rFVIIa for cardiac surgical bleeding defined by stage of resuscitation, but the benefits of early administration remain unclear.

Logistical Considerations and Clinical Outcomes Associated With Converting Operating Rooms Into an Intensive Care Unit During the Coronavirus Disease 2019 Pandemic in a New York City Hospital.

BACKGROUND: Coronavirus disease 2019 (COVID-19) emerged as a public health crisis that disrupted normal patterns of health care in the New York City metropolitan area. In preparation for a large influx of critically ill patients, operating rooms (ORs) at NewYork-Presbyterian/Columbia University Irving Medical Center (NYP-Columbia) were converted into a novel intensive care unit (ICU) area, the operating room intensive care unit (ORICU). METHODS: Twenty-three ORs were converted into an 82-bed ORICU. Adaptations to the OR environment permitted the delivery of standard critical care therapies. Nonintensive-care-trained staff were educated on the basics of critical care and deployed in a hybrid staffing model. Anesthesia machines were repurposed as critical care ventilators, with accommodations to ensure reliable function and patient safety. To compare ORICU survivorship to outcomes in more traditional environments, we performed Kaplan-Meier survival analysis of all patients cared for in the ORICU, censoring data at the time of ORICU closure. We hypothesized that age, sex, and obesity may have influenced the risk of death. Thus, we estimated hazard ratios (HR) for death using Cox proportional hazard regression models with age, sex, and body mass index (BMI) as covariables and, separately, using older age (65 years and older) adjusted for sex and BMI. RESULTS: The ORICU cared for 133 patients from March 24 to May 14, 2020. Patients were transferred to the ORICU from other ICUs, inpatient wards, the emergency department, and other institutions. Patients remained in the ORICU until either transfer to another unit or death. As the hospital patient load decreased, patients were transferred out of the ORICU. This process was completed on May 14, 2020. At time of data censoring, 55 (41.4%) of patients had died. The estimated probability of survival 30 days after admission was 0.61 (95% confidence interval [CI], 0.52-0.69). Age was significantly associated with increased risk of mortality (HR = 1.05, 95% CI, 1.03-1.08, P < .001 for a 1-year increase in age). Patients who were ≥65 years were an estimated 3.17 times more likely to die than younger patients (95% CI, 1.78-5.63; P < .001) when adjusting for sex and BMI. CONCLUSIONS: A large number of critically ill COVID-19 patients were cared for in the ORICU, which substantially increased ICU capacity at NYP-Columbia. The estimated ORICU survival rate at 30 days was comparable to other reported rates, suggesting this was an effective approach to manage the influx of critically ill COVID-19 patients during a time of crisis.

Fatal COVID-19 in an MS patient on natalizumab: A case report.

We report a fatal case of COVID-19 in a 51-year-old African American woman with multiple sclerosis on natalizumab. She had multiple risk factors for severe COVID-19 disease including race, obesity, hypertension, and elevated inflammatory markers, but the contribution of natalizumab to her poor outcome remains unknown. We consider whether altered dynamics of peripheral immune cells in the context of natalizumab treatment could worsen the cytokine storm syndrome associated with severe COVID-19. We discuss extended interval dosing as a risk-reduction strategy for multiple sclerosis patients on natalizumab, and the use of interleukin-6 inhibitors in such patients who contract COVID-19.

Provider Counseling About and Risk Perception for Future Chronic Disease Among Women with Gestational Diabetes and Preeclampsia.

Background: Women diagnosed with gestational diabetes or preeclampsia are at a greater risk of developing future type 2 diabetes mellitus, high blood pressure, and cardiovascular disease. Increased perception of future chronic disease risk is positively associated with making health behavior changes, including in pregnant women. Although gestational diabetes is a risk factor for type 2 diabetes, few women have heightened risk perception. Little research has assessed receipt of health advice from a provider among women with preeclampsia and its association with risk perception regarding future risk of high blood pressure and cardiovascular disease. Among women with recent diagnoses of preeclampsia or gestational diabetes, we assessed associations between receipt of health advice from providers, psychosocial factors, and type of pregnancy complication with risk perception for future chronic illness. Methods: We conducted a cross-sectional analysis among 79 women diagnosed with preeclampsia and/or gestational diabetes using surveys and medical record abstraction after delivery and at 3 months postpartum. Results: Overall, fewer than half of the 79 women with preeclampsia and gestational diabetes reported receiving health advice from a provider, and women with preeclampsia were significantly less likely to receive counseling as compared with women with gestational diabetes (odds ratio 0.23). We did not identify a difference in the degree of risk perception by pregnancy complication or receipt of health advice. There were no significant differences in risk perception based on age, race, education, or health insurance coverage. Conclusions: We demonstrated that women with preeclampsia and gestational diabetes are not routinely receiving health advice from providers regarding future chronic disease risk, and that women with preeclampsia are less likely to be counseled on their risk, compared with women with gestational diabetes. Provider and patient-centered interventions are needed to improve postpartum care and counseling for women at high risk for chronic disease based on recent pregnancy complications.

Opioid use disorder incidence and treatment among incarcerated pregnant women in the United States: results from a national surveillance study.

BACKGROUND AND AIMS: The established standard care in pregnancy is medication for opioid use disorder (MOUD); however, many institutions of incarceration do not have MOUD available. We aimed to describe the number of incarcerated pregnant women with opioid use disorder (OUD) in the United States and jails' and prisons' MOUD in pregnancy policies. DESIGN: Epidemiological surveillance study of 6 months of outcomes of pregnant, incarcerated women with OUD and cross-sectional survey of institutional policies. SETTING: United States. PARTICIPANTS: Twenty-two state prison systems and six county jails. MEASUREMENTS: The number of pregnant women with OUD admitted and treated with methadone, buprenorphine or withdrawal; policies on provision of MOUD and withdrawal in pregnancy. FINDINGS: Twenty-six per cent of pregnant women admitted to prisons and 14% to jails had OUD. One-third were managed through withdrawal. The majority who were prescribed MOUD were on methadone (78%, prisons; 81%, jails), not buprenorphine. While most sites (n = 18 prisons, n = four jails) continued pre-incarceration MOUD in pregnancy, very few initiated in custody (n = four prisons; n = two jails). Two-thirds of prisons and three-quarters of jails providing MOUD in pregnancy discontinued it postpartum. CONCLUSIONS: In this sample of US prisons and jails, one-third required pregnant women with opioid use disorder to go through withdrawal, contrary to medical guidelines. More women were prescribed methadone than buprenorphine, despite the fewer regulatory barriers on prescribing buprenorphine. Most sites stopped medication for opioid use disorder postpartum, signaling prioritization of the fetus, not the mother. Pregnant incarcerated women with opioid use disorder in the United States frequently appear to be denied essential medications and receive substandard medical care.

Acute kidney injury after cardiac surgery: A comparison of different definitions.

AIM: Acute kidney injury (AKI) after cardiac surgery increases morbidity and mortality. Different definitions for AKI have been used such as Acute Kidney Injury Network (AKIN), Kidney Disease: Improving Global Outcomes (KDIGO) or risk, injury, failure, loss, end-stage kidney disease (RIFLE). The aim of this study is to determine the best definition of AKI after cardiac surgery with the largest impact on the outcome. METHODS: This retrospective study of cardiac surgery patients compared the incidence and effect on outcome (90-day and 1-year mortality) of different definitions of AKI: RIFLE, AKIN and KDIGO. Additionally, we defined transient AKI (increase in serum creatinine that resolved in <72 hours), sustained (increase in serum creatinine within 48 hours that remained for >72 hours), and late (increase in serum creatinine after 48 hours). RESULTS: Of the included 1551 patients, 410 patients developed AKI defined by AKIN criteria, 449 defined by KDIGO and 217 defined by RIFLE-Risk criteria. Hundred and nine patients developed transient AKI (6.9%), 183 patients had sustained AKI (11.6%), and 106 patients had late AKI (6.7%). The best definition with the highest positive likelihood ratio was RIFLE-Risk (positive likelihood ratio = 2.32) followed by "sustained AKI" (positive likelihood ratio = 2.27). AKI defined by AKIN criteria missed all 80 patients with late AKI and 39 patients with KDIGO AKI. CONCLUSION: Risk, injury, failure, loss, end-stage kidney disease-risk was the best definition of AKI as determined by the ability to predict short-term mortality. A substantial number of patients developed AKI only after 48 hours, and these were missed when using AKIN criteria. AKIN criteria are not sensitive enough to capture all episodes of AKI in this population.

Types and quality of physical therapy research publications: has there been a change in the past decade?

PURPOSE: To describe and compare the type and quality of evidence published in physical therapy (PT) journals during two time periods (2000-2002 vs. 2010-2012) and to explore scientific editors' opinions on changes in the types and quality of articles. METHODS: A quantitative, longitudinal, retrospective journal review was used to categorize and assess the methodological rigour of items published in four PT journals using the Hedges Project. A quantitative, descriptive, cross-sectional survey explored the opinions of scientific editors. Percentages and frequencies of article types (as defined by the Hedges Project criteria), items passing rigour, and editor responses were calculated. Statistical significance of differences in article type and rigour between the two time periods was determined using Fisher's Exact Test. RESULTS: There was a significant increase in original studies and review articles from 2000-2002 to 2010-2012 (p<0.001, p=0.002, respectively). The overall pass rate for rigour was 33.3% in 2000-2002 and 42.5% in 2010-2012, showing a significant increase (p=0.019). The majority of editors reported an increase in systematic reviews, qualitative designs, and randomized controlled trials and believed that quality had improved by 2010-2012. CONCLUSION: From 2000-2002 to 2010-2012, the quality of articles published in PT journals improved and the proportion of original studies and review articles increased.

Objectif : Décrire et comparer le type et la qualité des données probantes publiées dans les revues de physiothérapie de deux périodes (2010­2012 et 2000­2002) et explorer les opinions des rédacteurs scientifiques sur l'évolution du type et de la qualité des articles. Méthodes : Un examen rétrospectif quantitatif et longitudinal des revues a permis de classer par catégorie les articles publiés dans quatre revues de physiothérapie et d'évaluer leur rigueur méthodologique, grâce au projet Hedges. Une étude transversale descriptive quantitative a permis d'explorer les opinions des rédacteurs scientifiques. Les pourcentages et les fréquences des types d'article (selon la définition des critères du projet Hedges), les articles d'une rigueur suffisante et les réponses des rédacteurs ont été calculés. La signification statistique des différences dans le type et la rigueur des articles entre les deux périodes a été déterminée à l'aide de la méthode exacte de Fisher. Résultats : Il y a eu une importante augmentation dans le nombre d'études originales et d'exposés de synthèse de 2000­2002 à 2010­2012 (p<0,001, p=0,002, respectivement). Le taux de réussite global pour ce qui est de la rigueur était de 33,3% en 2000­2002 et de 42,5% en 2010­2012, ce qui constitue une augmentation importante (p=0,019). La majorité des rédacteurs ont signalé une augmentation des examens systématiques, des conceptions qualitatives, et des essais contrôlés randomisés, et ils étaient d'avis que la qualité s'était améliorée. Conclusion : De 2000­2002 à 2010­2012, la qualité des articles publiés dans les revues de physiothérapie s'est améliorée et la proportion d'études originales et d'exposés de synthèses a augmenté.
