Fetal Heart Rate Monitoring

Abstract: Electronic fetal heart rate monitoring is a widely utilized means of assessment of fetal status during labor. Whereas little evidence exists regarding efficacy, this modality continues to be used extensively in every modern labor and delivery unit in developed countries. It is of importance that all providers of health care to the woman in labor and her newborn have a clear understanding of the basic pathophysiology of fetal heart rate monitoring and an appreciation for labor course and concerns as they arise in order to optimize outcomes and patient safety.

Vacuum resin impregnation process

Abstract: A process and system for vacuum impregnation of a fiber reinforcement, such as carbon cloth, with a resin to produce a resin-fiber composite. Liquid resin enters in arrangement or system comprising a fiber reinforcement layer on a tool or mold and is directed via a system of flow paths to impregnate the fiber reinforcement layer uniformly across the width thereof and along the length of the fiber reinforcement layer. According to one embodiment, a fiber reinforcement layer, e.g., carbon cloth, is placed on a tool. A porous paring film is applied over the fiber reinforcement layer and a bleeder layer, e.g., fiberglass, is applied over the parting film. A non-pourous film is placed over the bleeder layer, a breather cloth, e.g., fiberglass, is then applied over the non-porous film, and a vacuum bag is placed over the entire assembly and sealed to the mold surface. Liquid resin is fed to the assembly within the vacuum bag. Resin spreader means, e.g., a transverse strip of fiberglass cloth, or mechanical means, such as a slotted tube, receives the liquid resin and distributes it initially across the panel adjacent one end of the reinforcement layer after the vacuum has been applied to the assembly. The liquid resin is drawn through the bleeder cloth and through the fiber reinforcement layer from one end to the opposite thereof to completely impregnate same. The resin system is designed so that it will commence to gel when the liquid resin has completely impregnated the fiber reinforcement layer.

Perceptions of power and interactional dominance in interpersonal relationships

Abstract: This investigation uses dyadic power theory (Dunbar, 2000, 2004; Rollins & Bahr, 1976) to examine the relationship between dominance and power and the behavioral manifestations of power in close relationships. Ninety-seven couples (58 married, 39 cohabiting) completed a problem-solving task together while being videotaped. The videotapes were coded for a variety of verbal and nonverbal dominant control attempts including dysfluencies, interruptions, frequency of adaptor and illustrator gestures, vocal characteristics, and general perceptions of dominance. The results revealed that individuals’ perceptions of power led to more dominant communication behavior during discussions with their partner. Comparisons between the perceptions of participants and observers and the implications for future research are also discussed.

Accuracy of Needle Placement into the Intra-Articular Space of the Knee

Abstract: Background: To achieve their potential therapeutic benefit, hyaluronic acid derivatives should be injected directly into the knee joint space and not into the anterior fat pad or the subsynovial tissues. In the absence of a knee effusion, reproducible needle placement into the intra-articular space presents a challenge to the clinician. Methods: The accuracy of needle placement was assessed in a prospective series of 240 consecutive injec- tions in patients without clinical knee effusion. The injections were performed by one orthopaedic surgeon us- ing a 2.0-in (5.1-cm) 21-gauge needle through three commonly employed knee joint portals: anteromedial, anterolateral, and lateral midpatellar. Accuracy rates for needle placement were confirmed with fluoroscopic im- aging to document the dispersion pattern of injected contrast material. Results: Of eighty injections performed through an anterolateral portal, fifty-seven were confirmed to have been placed in the intra-articular space on the first attempt (an accuracy rate of 71%). Sixty of eighty injections per- formed through an anteromedial approach were intra-articular on the first attempt (75% accuracy rate), as were seventy-four of eighty injections performed through a lateral midpatellar portal (93% accuracy rate). Conclusions: Using real-time fluoroscopic imaging with contrast material, we demonstrated the difficulty of ac- curately placing a needle into the intra-articular space of the knee when an effusion is not present. This study revealed that a lateral midpatellar injection (an injection into the patellofemoral joint) was intra-articular 93% of the time and was more accurate than injections performed by the same orthopaedic surgeon using either of the other two portals. This study highlights the need for clinicians to refine injection techniques for delivering intra- articular therapeutic substances that are intended to coat the articular surfaces of the knee joint.

Understanding Impulsive Aggression: Angry Rumination and Reduced Self-Control Capacity Are Mechanisms Underlying the Provocation-Aggression Relationship

Abstract: Interpersonal provocation is a common and robust antecedent to aggression. Four studies identified angry rumination and reduced self-control as mechanisms underlying the provocation—aggression relationship. Following provocation, participants demonstrated decreased self-control on an unpleasant task relative to a control condition (Study 1). When provoked, rumination reduced self-control and increased aggression. This effect was mediated by reduced self-control capacity (Study 2). State rumination following provocation, but not anger per se, mediated the effect of trait rumination on aggression (Study 3). Bolstering self-regulatory resources by consuming a glucose beverage improved performance on a measure of inhibitory control following rumination (Study 4). These findings suggest that rumination following an anger-inducing provocation reduces self-control and increases aggression. Bolstering self-regulatory resources may reduce this adverse effect.
