Effect of Ventilator Mode on Ventilator-Free Days in Critically Ill Adults: A Randomized Trial.

Rationale: For critically ill adults receiving invasive mechanical ventilation, the ventilator mode determines how breaths are delivered. Whether the choice of ventilator mode affects outcomes for critically ill patients is unknown. To compare the effects of three common ventilator modes (volume control, pressure control, and adaptive pressure control) on death and duration of mechanical ventilation.

Long-term brain fog and cognitive impairment in previously hospitalized COVID-19 patients.

Objectives: Limited research exists on COVID-19 associated brain fog, and on the long-term cognitive and psychiatric sequelae in racially and ethnically diverse patients. We characterize the neuropsychological sequelae of post-acute COVID-19 in a diverse cohort and investigate whether COVID-19 clinical severity remains associated with brain fog and cognitive deficits approximately 2 years post infection.

Methods: A cross-sectional study of patients with a history of COVID-19 hospitalization (March-September 2020).

Protocol and Statistical Analysis Plan for the Mode of Ventilation During Critical Illness (MODE) Trial.

Background: For every critically ill adult receiving invasive mechanical ventilation, clinicians must select a mode of ventilation. The mode of ventilation determines whether the ventilator directly controls the tidal volume or the inspiratory pressure. Newer hybrid modes allow clinicians to set a target tidal volume; the ventilator controls and adjusts the inspiratory pressure.

Life threatening hemorrhage associated with a dentigerous cyst in a dog: Case report.

Dentigerous cysts are the most common type of odontogenic cysts and arise from an unerupted tooth. These cysts have stereotypical radiographic and clinical findings. They can be extremely invasive but rarely present as a life-threatening emergency.

Development of a reference interval for urinary ammonia-to-creatinine ratio in feline patients.

Background: Disruption of acid-base homeostasis can lead to many clinical problems. Ammonia excretion by the kidneys is critical to maintaining acid-base homeostasis through bicarbonate production. Measurement of ammonia excretion may help determine if the kidneys are properly functioning in maintaining acid-base balance.

Online mindfulness training for older adults during the COVID-19 pandemic: a randomized controlled trial using a multi-method assessment approach.

Objectives: The COVID-19 pandemic drastically accelerated the need for studies examining the effectiveness of programs to bolster psychological well-being, particularly for at-risk groups, such as older adults (OAs). Mindfulness Training (MT) has been suggested as a well-suited program for this purpose. The present study examined the impact of a 4-week online, trainer-led MT course tailored for OAs during the early months of the COVID-19 pandemic.

Protocol and statistical analysis plan for the Mode of Ventilation During Critical IllnEss (MODE) trial.

Introduction: For every critically ill adult receiving invasive mechanical ventilation, clinicians must select a mode of ventilation. The mode of ventilation determines whether the ventilator directly controls the tidal volume or the inspiratory pressure. Newer hybrid modes allow clinicians to set a target tidal volume, for which the ventilator controls and adjusts the inspiratory pressure.

Measuring the Frailty Phenotype and its Association with Cognition in Mid-Life and Older Age.

Background: Frailty is directly linked to physical robustness and cognitive decline in older age. The Fried Frailty phenotype (FP) is a construct composed of five core symptoms that has been studied predominately in older age. There is little research contrasting the psychometric properties of the FP in mid-life versus older age.

Protocolized Postextubation Respiratory Support to Prevent Reintubation: A Randomized Clinical Trial.

Respiratory support (noninvasive ventilation or high-flow nasal cannula) applied at the time of extubation has been reported to reduce reintubation rates, but concerns regarding effectiveness have limited uptake into practice. To determine if providing postextubation respiratory support to all patients undergoing extubation in a medical ICU would decrease the incidence of reintubation. We conducted a pragmatic, two-armed, cluster-crossover trial of adults undergoing extubation from invasive mechanical ventilation between October 1, 2017, and March 31, 2019, in the medical ICU of an academic medical center.

Protocolized Post-Extubation Respiratory Support to prevent reintubation: protocol and statistical analysis plan for a clinical trial.

Introduction: Following extubation from invasive mechanical ventilation, nearly one in seven critically ill adults requires reintubation. Reintubation is independently associated with increased mortality. Postextubation respiratory support (non-invasive ventilation or high-flow nasal cannula applied at the time of extubation) has been reported in small-to-moderate-sized trials to reduce reintubation rates among hypercapnic patients, high-risk patients without hypercapnia and low-risk patients without hypercapnia.

Does mindfulness training help working memory 'work' better?

There has been a proliferation of mindfulness training (MT) programs offered across a multitude of settings, including military, business, sports, education, and medicine. As such, ascertaining training effectiveness and determining best practices for program delivery are of the utmost importance. MT is often introduced to promote an array of desired effects from better mood, better leadership and management skills, to improved workplace or academic performance.

Revisiting eligibility for deep brain stimulation: Do preoperative mood symptoms predict outcomes in Parkinson's disease patients?

Introduction: Anxiety and depression are common in PD, occurring in an estimated 30%-40% of PD patients. However, the extent to which these emotional symptoms interfere with Deep Brain Stimulation (DBS) outcomes is not well established. This study examined the association between pre-operative emotional well-being and postsurgical cognitive, emotional, and motor performance in PD.

Benefits of mindfulness training for patients with progressive cognitive decline and their caregivers.

New strategies are needed to help people cope with the repercussions of neurodegenerative disorders such as Alzheimer's disease. Patients and caregivers face different challenges, but here we investigated an intervention tailored for this combined population. The program focused on training skills such as attending to the present moment nonjudgmentally, which may help reduce maladaptive emotional responses.

Labor pain management other than neuraxial: what do we know and where do we go next?

Analgesia and coping with labor pain can prevent suffering during childbirth. Nonpharmacologic methods help women manage labor pain. Strong evidence is available for the efficacy of continuous one-to-one support from a woman trained to provide nonmedical care during labor, immersion in warm water during first-stage labor, and sterile water injected intracutaneously or subcutaneously at locations near a woman's lumbosacral spine to reduce back-labor pain.

The language of birth.

Our language both reflects and influences our attitudes and behavior. This Roundtable Discussion explores the language used in obstetrics and in the interactions between caregivers and women or their families: What do practitioners say to mothers and families during labor? At birth? In consultations? To describe what is happening? To encourage a woman's efforts? To lighten the atmosphere? When advising about possible interventions? Medical terminology in perinatal care can often be deceptive or confusing, not only for mothers but for caregivers. The authors of this Roundtable, representing health professionals from different specialties and interests in the field, have examined some examples of such language use, misuse, and abuse in perinatal care.

Non-invasive detection of pulmonary pathogens in ventilator-circuit filters by PCR.

Ventilator associated pneumonia is a common and costly complication in critically ill and injured surgical patients. The diagnosis of pneumonia remains problematic and non-specific. Using clinical criteria, a diagnosis of pneumonia is typically not made until an infection is well established.

Safety and risks of nitrous oxide labor analgesia: a review.

Introduction: This review of the safety and risks of nitrous oxide (N(2) O) labor analgesia presents results of a search for evidence of its effects on labor, the mother, the fetus, the neonate, breastfeeding, and maternal-infant bonding. Concerns about apoptotic damage to the brains of immature mammals exposed to high doses of N(2) O during late gestation, possible cardiovascular risks from hyperhomocysteinemia caused by N(2) O, a hypothesis that children exposed to N(2) O during birth are more likely to become addicted to amphetamine drugs as adults, and possible occupational risks for those who provide care to women using N(2) O/O(2) labor analgesia are discussed in detail.

Methods: Research relevant to the 4 special concerns and to the effects of N(2) O analgesia on labor and the mother-child dyad were examined in depth.

Oxytocin as a "high alert medication": a multilayered challenge to the status quo.

Oxytocin is the drug most commonly associated with preventable adverse perinatal outcomes. In 2007 it was added to the Institute for Safe Medication Practices short list of medications "bearing a heightened risk of harm," which may "require special safeguards to reduce the risk of error." In January 2009 the American Journal of Obstetrics and Gynecology published a Clinical Opinion paper about oxytocin's inclusion on the list and how the obstetrics profession in the United States should respond.

Marginalization of midwives in the United States: new responses to an old story.

This column addresses issues raised by an intensive study of the circumstances and actions that resulted in the closure of two long-standing, successful nurse-midwifery services in a large United States city in 2003. Dr. Steffie Goodman of the School of Nursing, University of Colorado Health Science Center in Denver, USA, conducted 52 in-depth interviews with midwives, nurses, administrators, childbirth educators, policymakers, and physicians in an effort to understand how and why these two services were closed and what their closures revealed about the general underutilization of midwives in contemporary U.

Why do women go along with this stuff?

Normal childbirth has become jeopardized by inexorably rising interventions around the world. In many countries and settings, cesarean surgery, labor induction, and epidural analgesia continue to increase beyond all precedent, and without convincing evidence that these actions result in improved outcomes (1,2). Use of electronic fetal monitoring is endemic, despite evidence of its ineffectiveness and consequences for most parturients (1,3); ultrasound examinations are too often done unnecessarily, redundantly, or for frivolous rather than indicated reasons (4); episiotomies are still routine in many settings despite clear evidence that this surgery results in more harm than good (5); and medical procedures, unphysiological positions, pubic shaving and enemas, intravenous lines, enforced fasting, drugs, and early mother-infant separation are used unnecessarily (1).
