Conventional venoarterial extracorporeal membrane oxygenation (VA-ECMO) places a functional afterload burden on the left ventricle. In the setting of acute severe aortic insufficiency-induced cardiogenic shock, the utility of VA-ECMO in combination with a failing valve may result in catastrophic haemodynamic consequences. This challenge is compounded when the culprit is a failing surgical bioprosthetic valve.

Guided by the developmental theory of embodiment, the current study explored feminist embodiment as a protective factor that may simultaneously promote more positive (and less negative) body talk and body image outcomes among mothers and their young adult daughters. Results from an expanded actor-partner interdependence model (APIM; N = 169 dyads) revealed that our construct of feminist embodiment, which was composed of feminist attitudes, mind-body connection, and psychological empowerment, has potential benefits for both mothers and daughters. Specifically, actor effects indicated that feminist embodiment was positively associated with both mothers' and daughters' body image, and it was indirectly associated with both women's own body image through more positive (and less negative) body talk.

Little is known about how fat talk - a verbal expression of body image concerns - functions within romantic relationships. This study used vignettes about a fictional couple to examine how varied levels of a woman's fat talk were perceived by participants as affecting a fictional couple's relationship and sexual satisfaction. Participants were recruited from Amazon Mechanical Turk and included 239 heterosexual people (127 men, 112 women) with long-term relationship experience.

Objective: Adult picky eating (PE) has received increased attention in the eating behavior literature due to its important association with adult avoidant-restrictive food intake disorder (ARFID). The current study tested a model of potential risk factors of adult PE behavior, including perceived early parental feeding practices. An exploratory model was also utilized to understand associations with different aspects of adult PE behaviors.

Pump-limited kW-class operation in a multimode fiber amplifier using adaptive mode control and a photonic lantern front end was achieved. An array of three single-mode fiber inputs was used to adaptively inject the appropriate superposition of input modes in a three-mode gain fiber to achieve the desired mode at the output. Mode fluctuations at high power were compensated by adjusting the relative phase, amplitude, and polarization of the single-mode fiber inputs.

Fat talk (FT) involves critiquing one's own appearance in social conversations. Although peers are known to prompt FT behavior, there has been little exploration of the influence of mothers and research has not distinguished between self-reported FT and perceptions of FT. This study addresses this research gap by investigating the relationships between participants' FT and corresponding FT of both self-reported and perceived FT of their mothers and friends.

Interpersonal violence (IPV) in adolescence is a serious public health concern and may have lasting behavioral effects and implications for adult relationships. Adolescents from 2 rural Appalachian high schools in 2011/2012 were surveyed using the Centers for Disease Control and Prevention Youth Risk Behavioral Surveillance (YRBS) survey, which assessed (a) physical IPV within a dating relationship, (b) sexual IPV (defined as forced sex/rape), and (c) those who experienced both. We present baseline rates of each form of IPV for these rural male and female adolescents and assessed the strength and statistical significance of these associations between physical and sexual IPV and other risk factors using χ2 tests and relative risk ratios.

This study examined men's perceptions of women engaging in "Fat Talk," a style of conversation that expresses discontent towards one's physical appearance, especially focusing on and criticizing body fat, shape, and weight. Male undergraduates were shown a vignette illustrating a courting scenario wherein the target female's body size was manipulated to be "sexy" and: (a) "lean," (b) "average," or (c) "larger." And to another woman, the men overheard the target female either: (a) self-degrade herself (fat talk) or (b) self-accept herself.

We demonstrate adaptive-spatial mode control (ASMC) in few-moded double-clad large mode area (LMA) fiber amplifiers by using an all-fiber-based photonic lantern. Three single-mode fiber inputs are used to adaptively inject the appropriate superposition of input modes in a multimode gain fiber to achieve the desired mode at the output. By actively adjusting the relative phase of the single-mode inputs, near-unity coherent combination resulting in a single fundamental mode at the output is achieved.

Picky eating is a childhood behavior that vexes many parents and is a symptom in the newer diagnosis of Avoidant/Restrictive Food Intake Disorder (ARFID) in adults. Pressure to eat, a parental controlling feeding practice aimed at encouraging a child to eat more, is associated with picky eating and a number of other childhood eating concerns. Low intuitive eating, an insensitivity to internal hunger and satiety cues, is also associated with a number of problem eating behaviors in adulthood.

Objectives: Diffuse isolated liver metastases are the dominant mode of tumor progression in a number of cancers and present a major treatment challenge for oncologists. An experimental treatment, percutaneous hepatic perfusion (PHP), utilizes partial venovenous cardiopulmonary bypass to allow administration of high-dose chemotherapy directly and solely to the liver with filtration of chemotherapeutic agents from the blood prior to its return to the systemic circulation, thereby minimizing toxic systemic effects. The following case series describes the management of 5 patients with metastatic melanoma undergoing serial PHPs.

Sociocultural norms pertaining to an ideal of thinness for women likely play a role in the development and maintenance of disturbance in body image, and by extension, disordered eating. However, competing norms associated with feminism may buffer women from pressures associated with achieving the thin ideal. The present study explored the relationship between feminist ideology, empowerment, and self-efficacy relative to body image and eating behavior with a sample of U.
