Self-Compassion and Psychological Well-Being of Childhood Sexual Abuse Survivors: Emotional Dysregulation and Trauma-Related Shame as Mediators.

In this study, we explored explanations for the link between self-compassion and psychological well-being among a sample of adult childhood sexual abuse (CSA) survivors in the United States ( = 335). Informed by Neff's self-compassion theory, we hypothesized that the relationship between self-compassion and psychological well-being would be partially explained by a reduction in emotional dysregulation and trauma-related shame. We tested a parallel multiple mediation model with (a) emotion dysregulation and (b) trauma-related shame as the mediators.

Background: The ideal dose and specific prothrombin complex concentrate (PCC) for warfarin reversal is unknown.

Objective: To evaluate the reduction in international normalized ratio (INR) of 3 different PCC dosing regimens: fixed-dose activated 4-factor PCC (aPCC), fixed-dose 4-factor PCC (4PCC), and standard-dose 4PCC.

Methods: This was a multicenter retrospective cohort review.

Azithromycin Prophylaxis in an Adolescent With PANDAS.

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) is a type of pediatric obsessive-compulsive disorder with an acute symptom onset and periodic recurrence that is triggered by streptococcal infection. Due in part to the multifaceted assessment involved in the diagnosis of PANDAS and lack of consensus on the best treatment, management of these cases is complex. A background and case of PANDAS exacerbation in an adolescent patient, who presented with visuomotor impairment and was treated with azithromycin (Zithromax, Pfizer, New York, NY) prophylaxis to prevent further clinical deterioration, is described here.

Progression and stop organization reveals conservation of movement organization during dark exploration across rats and mice.

Spatial orientation is a ubiquitous feature of animal behavior. Environmental and self-movement cues are sources of information used to maintain spatial orientation. The literature has typically focused on differences between mice and rats using environmental cues to guide movement.

Making waves: Comparing Morris water task performance in rats and prairie voles.

Spatial processing is a critical component for survival. This domain of information processing has been extensively studied in rats and mice. Limited work has examined the capacity of other rodent species, like the prairie vole (Microtus ochrogaster), to process spatial information.

Otolith dysfunction alters exploratory movement in mice.

The organization of rodent exploratory behavior appears to depend on self-movement cue processing. As of yet, however, no studies have directly examined the vestibular system's contribution to the organization of exploratory movement. The current study sequentially segmented open field behavior into progressions and stops in order to characterize differences in movement organization between control and otoconia-deficient tilted mice under conditions with and without access to visual cues.

Unilateral lesions of the dorsocentral striatum (DCS) disrupt spatial and temporal characteristics of food protection behavior.

Spatial and temporal information processing provide a foundation for higher cognitive functions. The survival of animals depends on integrating spatial and temporal information to organize behavior. In general, previous research has focused on only one source of information processing; however, there is evidence to support a convergence in the processing of egocentric-spatial and temporal information within a cortico-striatal system of structures.

The medial frontal cortex contributes to but does not organize rat exploratory behavior.

Animals use multiple strategies to maintain spatial orientation. Dead reckoning is a form of spatial navigation that depends on self-movement cue processing. During dead reckoning, the generation of self-movement cues from a starting position to an animal's current position allow for the estimation of direction and distance to the position movement originated.

A history of adolescent binge drinking in humans is associated with impaired self-movement cue processing on manipulatory scale navigation tasks.

A binge drinking pattern of alcohol consumption has been shown to have an impact on brain structures that continue to develop into late adolescence. These same brain structures have been implicated in processing self-movement cues. The current study applies an array of existing and novel kinematic analysis techniques to characterize performance on manipulatory scale tasks to assess spatial orientation deficits associated with a history of adolescent binge drinking.

Cholinergic deafferentation of the hippocampus causes non-temporally graded retrograde amnesia in an odor discrimination task.

Dementia of the Alzheimer's type (DAT) is a neurodegenerative disorder marked by loss of hippocampal cholinergic tone and significant memory impairments, specifically for memories acquired prior to disease onset. The nature of this relationship, however, remains debated. The current study used the string pulling task to evaluate the temporal effects of odor discrimination learning in animals with selective cholinergic lesions to determine the role of the septohippocampal cholinergic system in mnemonic function.

Otolithic information is required for homing in the mouse.

Navigation and the underlying brain signals are influenced by various allothetic and idiothetic cues, depending on environmental conditions and task demands. Visual landmarks typically control navigation in familiar environments but, in the absence of landmarks, self-movement cues are able to guide navigation relatively accurately. These self-movement cues include signals from the vestibular system, and may originate in the semicircular canals or otolith organs.

Survey of carboplatin dosing strategies in oncology practices.

Objectives: To identify variations in carboplatin dose calculations at oncology institutions and practices in the southeastern United States.

Methods: 500 surveys were mailed to oncology practices in the southeastern United States to assess variations in carboplatin doses. The survey sought to determine assumptions that are made regarding carboplatin calculations and if different carboplatin doses result when participants are given the same data and patient characteristics.

Diabetic ketoacidosis depletes plasma tryptophan.

Diabetic ketoacidosis (DKA) is a severe metabolic disturbance of insulin-dependent diabetes mellitus (IDDM) which has a significant effect on amino acid metabolism. Amino acids serve as precursors for various neurotransmitters which are involved in affective disorders, and patients with IDDM are known to have an increased prevalence of affective disorders. We monitored the plasma concentrations of 23 amino acids in six adolescents prior to treatment of DKA and at 6, 24 and 120 hours after initiation of treatment.

Conidial movement of nontoxigenic Aspergillus flavus and A. parasiticus in peanut fields following application to soil.

The use of nontoxigenic strains of Aspergillus flavus and A. parasiticus in biological control effectively reduces aflatoxin in peanuts when conidium- producing inoculum is applied to the soil surface. In this study, the movement of conidia in soil was examined following natural rainfall and controlled precipitation from a sprinkler irrigation system.

Propofol sedation for endoscopic procedures in children.

Background And Study Aims: Propofol sedation has been used successfully in various outpatient minor procedures in children. Limited data are available on the usefulness of propofol sedation during gastrointestinal endoscopic procedures in children. The aim of this study was to evaluate our experience of propofol sedation in pediatric gastrointestinal endoscopic procedures.

Effect of Aspergillus parasiticus soil inoculum on invasion of peanut seeds.

Environmental control plots adjusted to late season drought and elevated soil temperatures were inoculated at peanut planting with low and high levels of conidia, sclerotia, and mycelium from a brown conidial mutant of Aspergillus parasiticus. Percentage infection of peanut seeds from undamaged pods was greatest for the subplot containing the high sclerotial inoculum (15/cm2 soil surface). Sclerotia did not germinate sporogenically and may have invaded seeds through mycelium.

Performance of two immunochemical assays in the analysis of peanuts for aflatoxin at 37 field laboratories.

A study was conducted to measure the precision of 2 rapid aflatoxin assay systems in use at 37 peanut buying points during the 1991 harvest season. Aflatoxin laboratories were established at the 37 buying points to analyze peanut samples from all incoming farmers' stock loads as part of a joint project sponsored by various segments of the U.S.

Use of a Biocompetitive Agent to Control Preharvest Aflatoxin in Drought Stressed Peanuts.

A three-year study was conducted to evaluate the use of a nonaflatoxin-producing strain of Aspergillus parasiticus (NRRL 13539) as a biocompetitive agent for the control of preharvest aflatoxin contamination of peanuts. The agent was added to the soil of the environmental control plot facility at the National Peanut Research Laboratory and tested by subjecting peanuts to optimal conditions for the development of aflatoxin contamination. Edible peanuts from the treated soil contained aflatoxin concentrations of 11, 1, and 40 ppb for crop years 1987, 1988, and 1989, respectively, compared to untreated peanuts with 531, 96, and 241 ppb, respectively.

Interrelationship of kernel water activity, soil temperature, maturity, and phytoalexin production in preharvest aflatoxin contamination of drought-stressed peanuts.

Samples of Florunner peanuts were collected throughout a period of late-season drought stress with mean geocarposphere temperatures of 29 and 25 degrees C, and determinations of maturity, kernel water activity (aw), percent moisture, capacity for phytoalexin production, and aflatoxin contamination were made. Results showed an association between the loss of the capacity of kernels to produce phytoalexins and the appearance of aflatoxin contamination. Kernel aw appeared to be the most important factor controlling the capacity of kernels to produce phytoalexins.

Color mutants of Aspergillus flavus and Aspergillus parasiticus in a study of preharvest invasion of peanuts.

A comparison of the invasion of flowers, aerial pegs, and kernels by wild-type and mutant strains of Aspergillus flavus or A. parasiticus along with aflatoxin analyses of kernels from different drought treatments have supported the hypothesis that preharvest contamination with aflatoxin originates mainly from the soil. Evidence in support of soil invasion as opposed to aerial invasion was the following.

Increased excretion of histidyl-L-proline diketopiperazine by infants receiving Pregestimil and Nutramigen formulas.

Histidyl-L-proline diketopiperazine is excreted in increased amounts by infants receiving Nutramigen or Pregestimil. When these formulas are discontinued, its excretion becomes undetectable. The compound was isolated from Nutramigen and Pregestimil, as well as from the urine of the infants receiving these formulas, and was identified by comparison with authentic histidyl-L-proline diketopiperazine standard in various chromatographic and electrophoretic systems.
