Pattern and time point of relapse in locally advanced esophagogastric adenocarcinoma after multimodal treatment: implications for a useful structured follow-up.

Purpose: Despite improvements in multimodal treatment of locally advanced esophagogastric adenocarcinoma, the majority of patients still relapses. The impact of structured follow-up for early detection of recurrence is unclear and controversially discussed.

Methods: Patients with locally advanced esophagogastric adenocarcinoma having received neoadjuvant/perioperative chemotherapy followed by tumor resection between 2009 and 2021, underwent a structured follow-up including three-monthly imaging during the first 2 years, followed by semiannual and annual examinations in year 3-4 and 5, respectively.

Motorized Robotic Closed Cervical Traction: Biomechanical Proof of Concept.

Study Design: Biomechanical study.

Objective: To demonstrate that robotic cervical traction can apply closed cervical traction as effectively as manual weight-and-pulley traction in extension spring and cadaveric models.

Summary Of Background Data: Closed cervical traction is used to reduce subaxial cervical spine dislocation injuries and to distract the intervertebral space during cervical spine surgery.

Cytokine release syndrome-like serum responses after COVID-19 vaccination are frequent and clinically inapparent under cancer immunotherapy.

Patients with cancer frequently receive immune-checkpoint inhibitors (ICIs), which may modulate immune responses to COVID-19 vaccines. Recently, cytokine release syndrome (CRS) was observed in a patient with cancer who received BTN162b2 vaccination under ICI treatment. Here, we analyzed adverse events and serum cytokines in patients with 23 different tumors undergoing (n = 64) or not undergoing (n = 26) COVID-19 vaccination under ICI therapy in a prospectively planned German single-center cohort study (n = 220).

The development of frustration regulation over early childhood: Links between attention diversion and parasympathetic activity.

Diverting attention away from negative emotional stimuli has been associated with calmer physiological states in the moment, but little is known about the potential long-term effects of this emotion regulation strategy on physiology. Similarly, how physiological states, in turn, may contribute to the development of regulatory behaviors has seldom been examined. The current study investigated the concurrent and prospective associations between children's parasympathetic activity and attention diversion during a frustrating experience over 2.

Irritability Predicts Hyperactive/Impulsive Symptoms Across Adolescence for Females.

Irritability is common in Attention-Deficit Hyperactivity Disorder (ADHD), but little is known about whether irritability predicts the course of ADHD symptoms over time. Adolescence is a dynamic period of emotional development as well as shifts in ADHD symptoms; an important goal is to identify youth at risk of increasing or persisting symptoms. We examined irritability as a longitudinal predictor of change in adolescents' ADHD symptoms, as well as how this link may differ in females versus males.

The Development of Generosity From 4 to 6 Years: Examining Stability and the Biopsychosocial Contributions of Children's Vagal Flexibility and Mothers' Compassion.

Individual differences in children's prosocial behaviors, including their willingness to give up something of value for the benefit of others, are rooted in physiological and environmental processes. In a sample of 4-year-old children, we previously found evidence that flexible changes in respiratory sinus arrhythmia (RSA) were linked to donation behavior, and that these physiological patterns may support greater sensitivity to the positive effects of compassionate parenting on donation behavior. The current study focused on a follow-up assessment of these children at age 6.

Considering context in the developmental psychobiology of self-regulation.

The developmental psychobiology of self-regulation in childhood has received increasing attention in recent years. As a next step in advancing research and theorizing about the processes by which early biological correlates of self-regulation are forged, a more nuanced consideration of the contexts in which these phenomena are embedded is needed. This review synthesizes insights from distinct but complementary approaches to studying the developmental psychobiology of early self-regulation, focusing on the idea of context at different time scales.

IgA-Mediated Killing of Tumor Cells by Neutrophils Is Enhanced by CD47-SIRPα Checkpoint Inhibition.

Therapeutic monoclonal antibodies (mAb), directed toward either tumor antigens or inhibitory checkpoints on immune cells, are effective in cancer therapy. Increasing evidence suggests that the therapeutic efficacy of these tumor antigen-targeting mAbs is mediated-at least partially-by myeloid effector cells, which are controlled by the innate immune-checkpoint interaction between CD47 and SIRPα. We and others have previously demonstrated that inhibiting CD47-SIRPα interactions can substantially potentiate antibody-dependent cellular phagocytosis and cytotoxicity of tumor cells by IgG antibodies both and IgA antibodies are superior in killing cancer cells by neutrophils compared with IgG antibodies with the same variable regions, but the impact of CD47-SIRPα on IgA-mediated killing has not been investigated.

Heart Rate Variability and Acute Stress Among Novice Airway Managers.

Background: The nature of medical emergencies places emergency physicians at risk for high levels of acute psychological stress (APS). Stress-modifying techniques like visualization, breath control, and mental practice may help mitigate APS, but objective markers of stress are difficult to measure in the clinical setting. We explored the relationship between heart rate variability (HRV), a real-time measure of autonomic arousal, and self-reported APS among emergency medicine (EM) residents learning to intubate on actual patients.

Immune Effector Functions of Human IgG2 Antibodies against EGFR.

Three FDA-approved epidermal growth factor receptor (EGFR) antibodies (cetuximab, panitumumab, necitumumab) are clinically available to treat patients with different types of cancers. Interestingly, panitumumab is of human IgG2 isotype, which is often considered to have limited immune effector functions. Unexpectedly, our studies unraveled that human IgG2 antibodies against EGFR mediated effective CDC when combined with another noncross-blocking EGFR antibody.

An intervention that increases parental sensitivity in families referred to Child Protective Services also changes toddlers' parasympathetic regulation.

Experiencing maltreatment in early childhood predicts poor parasympathetic regulation, characterized by low baseline parasympathetic activity and strong withdrawal of parasympathetic influence in response to tasks. The Promoting First Relationships (PFR) program improves parental sensitivity toward young children in families identified as maltreating. Using a subsample from a randomized control trial, we examined whether parental participation in PFR had lasting effects on toddlers' parasympathetic regulation, as measured by respiratory sinus arrhythmia (RSA), relative to a resource and referral control condition.

Linking autonomic physiology and emotion regulation in preschoolers: The role of reactivity and recovery.

Physiological recovery from negative emotions may be important for effective self-regulation, but little is known about recovery processes in children. The current study investigated links between autonomic physiology, anger expressions, and emotion regulation in a sample of eighty-three 3.5-year-olds.

On Measuring and Modeling Physiological Synchrony in Dyads.

Physiological synchrony within a dyad, or the degree of temporal correspondence between two individuals' physiological systems, has become a focal area of psychological research. Multiple methods have been used for measuring and modeling physiological synchrony. Each method extracts and analyzes different types of physiological synchrony, where 'type' refers to a specific manner through which two different physiological signals may correlate.

Parasympathetic Regulation and Inhibitory Control Predict the Development of Externalizing Problems in Early Childhood.

The current report examined the longitudinal relations between cognitive self-regulation, physiological self-regulation, and externalizing problems. At age 4 (n = 98; 49 girls) and 6 (n = 87; 42 girls), children completed the Day-Night task, which taps the inhibitory control dimension of executive function. During the task, cardiac activity was measured and respiratory sinus arrhythmia (RSA) was derived as an index of parasympathetic activity.

Moderate baseline vagal tone predicts greater prosociality in children.

Vagal tone is widely believed to be an important physiological aspect of emotion regulation and associated positive behaviors. However, there is inconsistent evidence for relations between children's baseline vagal tone and their helpful or prosocial responses to others (Hastings & Miller, 2014). Recent work in adults suggests a quadratic association (inverted U-shape curve) between baseline vagal tone and prosociality (Kogan et al.

Sympathetic recovery from anger is associated with emotion regulation.

Prior work has focused on how and whether autonomic reactivity in response to emotionally evocative events is associated with better emotion regulation skills in children, but little is known about autonomic recovery processes in children and how they might relate to regulation. In a sample of 67 3.5-year-olds, we examined sympathetic responding during an anger provocation and during a repair period immediately following.

[Intubating laryngeal tube suction disposable: Initial clinical experiences with a novel device for endotracheal intubation].

Background: According to the recent guidelines supraglottic airways, such as laryngeal tubes are recommended to ensure oxygenation in patients with unexpected difficult airways. The novel Intubating Laryngeal Tube Suction Disposable (iLTS-D) is a modified laryngeal tube designed for secondary tracheal intubation. This pilot study evaluated the use of the iLTS-D in clinical practice with respect to practicality and efficacy.

Roots and Benefits of Costly Giving: Children Who Are More Altruistic Have Greater Autonomic Flexibility and Less Family Wealth.

Altruism, although costly, may promote well-being for people who give. Costly giving by adults has received considerable attention, but less is known about the possible benefits, as well as biological and environmental correlates, of altruism in early childhood. In the current study, we present evidence that children who forgo self-gain to help other people show greater vagal flexibility and higher subsequent vagal tone than children who do not, and children from less wealthy families behave more altruistically than those from wealthier families.

Compassionate love buffers stress-reactive mothers from fight-or-flight parenting.

The links among mothers' compassionate love for their child, autonomic nervous system activity, and parenting behavior during less and more challenging mother-child interactions were examined. Mothers expressed and reported less negative affect when they exhibited autonomic patterns of increased parasympathetic dominance (high parasympathetic and low sympathetic activation) or autonomic coactivation (high parasympathetic and high sympathetic activation) during the less challenging interaction and autonomic coactivation during the more challenging interaction. Compassionate love predicted less reported and observed negativity in mothers who showed increased sympathetic nervous system dominance (high sympathetic and low parasympathetic activation).

How well socially wary preschoolers fare over time depends on their parasympathetic regulation and socialization.

Parasympathetic regulation and maternal overprotective parenting were examined in 101 children as moderators of links between preschool (M = 3.53 years) social wariness and childhood (M = 9.07 years) internalizing and anxiety problems, social skills, and scholastic performance.

Temperature and magnetic field dependence of a Kondo system in the weak coupling regime.

The Kondo effect arises due to the interaction between a localized spin and the electrons of a surrounding host. Studies of individual magnetic impurities by scanning tunneling spectroscopy have renewed interest in Kondo physics; however, a quantitative comparison with theoretical predictions remained challenging. Here we show that the zero-bias anomaly detected on an organic radical weakly coupled to a Au (111) surface can be described with astonishing agreement by perturbation theory as originally developed by Kondo 60 years ago.

The quantum magnetism of individual manganese-12-acetate molecular magnets anchored at surfaces.

The high intrinsic spin and long spin relaxation time of manganese-12-acetate (Mn(12)) makes it an archetypical single molecular magnet. While these characteristics have been measured on bulk samples, questions remain whether the magnetic properties replicate themselves in surface supported isolated molecules, a prerequisite for any application. Here we demonstrate that electrospray ion beam deposition facilitates grafting of intact Mn(12) molecules on metal as well as ultrathin insulating surfaces enabling submolecular resolution imaging by scanning tunneling microscopy.

Toward ultrafast time-resolved Debye-Scherrer x-ray diffraction using a laser-plasma source.

An elliptical glass capillary has been used to focus ultrashort Cu K alpha x-ray pulses emitted from a femtosecond laser-produced plasma. Due to its high magnification (7x), the optic transforms the divergent x-ray emission of the plasma into a quasicollimated x-ray beam with a divergence of only 0.18 degrees.
