Risk factors and temporal patterns of disordered eating differ in adolescent boys and girls: Testing gender-specific appearance anxiety models.

Adolescent dieting and disordered eating (DE) are risks for clinical eating disorders. In this five-wave longitudinal study, we tested gender-specific models linking early risk factors to temporal patterns of DE, considering appearance anxiety as a mediator. Participants were 384 Australian students (age 10 to 13; 45% boys) who reported their purging and skipping meals, experience with appearance-related teasing, media pressure, and appearance anxiety.

Self-determination theory and food-related parenting: The Parent Socioemotional Context of Feeding Questionnaire.

There has been wide application of Self-Determination Theory (SDT) to understanding motivation and regulation of eating and weight. Yet, there are no measures of the socioemotional-contextual family conditions in the eating domain, which are identified in SDT and should influence development of eating behavior in young children. Two studies were conducted to develop and validate a measure to assess the SDT socioemotional-contextual dimensions of food-related parenting.

Improved Perceptions of Emotion Regulation and Reflective Functioning in Parents: Two Additional Positive Outcomes of Parent-Child Interaction Therapy.

The purpose of this study was to test whether Parent-Child Interaction Therapy (PCIT), a widely used effective therapy for children's externalizing behaviors and parenting problems, was associated with improvements in parents' emotion regulation and reflective functioning. We also investigated whether these improvements had unique associations with children's improvements in externalizing and internalizing symptoms. Participants were 139 Australian children aged 29 to 83 months and their caregivers; all were referred for child externalizing behavior problems coupled with parenting skill deficits or high parent stress.

Intuitive, mindful, emotional, external and regulatory eating behaviours and beliefs: An investigation of the core components.

The aim of this study was to identify the interrelations between, and the core components of, adaptive and maladaptive measures of eating behaviours. Participants were 2018 females (M = 23.14 years) who completed measures of intuitive eating, mindful eating, overeating regulation, dietary restraint, emotional eating, external eating, and overeating dysregulation in contexts of leisure and discomfort.

Temporal context cues in human fear conditioning: Unreinforced conditional stimuli can segment learning into distinct temporal contexts and drive fear responding.

In associative learning, if stimulus A is presented in the same temporal context as the conditional stimulus (CS) - outcome association (but not in a way that allows an A-CS association to form) it becomes a temporal context cue, acquiring the ability to activate this context and retrieve the CS-outcome association. We examined whether a CS- presented during acquisition or extinction that predicted the absence of the unconditional stimulus (US) could act as a temporal context cue, reducing or enhancing responding, in differential fear conditioning. Two groups received acquisition (CSx-US, CSa-noUS) in phase 1 and extinction (CSx-noUS; CSe-noUS) in phase 2 (AE groups), and two groups received extinction in phase 1 and acquisition in phase 2 (EA groups).

Mitochondrial DNA defects and selective extraocular muscle involvement in CPEO.

PURPOSE. Chronic progressive external ophthalmoplegia (CPEO) is a prominent, and often the only, presentation among patients with mitochondrial diseases. The mechanisms underlying the preferential involvement of extraocular muscles (EOMs) in CPEO were explored in a comprehensive histologic and molecular genetic study, to define the extent of mitochondrial dysfunction in EOMs compared with that in skeletal muscle from the same patient.

Setting: Hospital-based clinical research centers.

Successful pregnancy outcome with the use of in vitro fertilization after Essure hysteroscopic sterilization.

Objective: To assess the compatibility of pregnancy after IVF and ET procedures with the presence of the Essure microinsert.

Design: Prospective, single-arm, clinical study (Canadian Task Force classification III).

Setting: Clinical research center.

Ultrasound: an effective method for localization of the echogenic Essure sterilization micro-insert: correlation with radiologic evaluations.

Study Objective: To examine the reliability and practicality of performing office-based transvaginal ultrasound for determining the ease of locating the Essure hysteroscopic sterilization micro-insert and compare its usefulness against established radiologic evaluations.

Design: Prospective single-center, single-arm, clinical study (Canadian Task Force classification xx).

Setting: Hospital-based clinical research center.

Essure hysteroscopic sterilization: results based on utilizing a new coil catheter delivery system.

Study Objective: To assess the safety and placement effectiveness of a new delivery catheter for the Essure micro-insert hysteroscopic sterilization system.

Design: Prospective, multicenter, single-arm clinical study. (Canadian Task Force classification II-3).

Microinsert nonincisional hysteroscopic sterilization.

Objective: To assess the safety, effectiveness, and reliability of a tubal occlusion microinsert for permanent contraception, as well as to document patient recovery from the placement procedure and overall patient satisfaction.

Methods: A cohort of 518 previously fertile women seeking sterilization participated in this prospective, phase III, international, multicenter trial. Microinsert placement was attempted in 507 women.

Hysteroscopic sterilization using a micro-insert device: results of a multicentre Phase II study.

Background: Unlike laparoscopic surgery for interval tubal sterilization, a hysteroscopic approach obviates surgical incision and requires only local anaesthesia or intravenous sedation. The safety, tolerability and efficacy of an hysteroscopically placed micro-insert device was evaluated.

Methods: A cohort of 227 previously fertile women participated in this prospective international multicentre trial.

The safety and effectiveness of a new hysteroscopic method for permanent birth control: results of the first Essure pbc clinical study.

Background: Current methods of female surgical sterilisation require incisional surgery, general anaesthesia and a prolonged recovery time. We studied the safety and effectiveness of Essure pbc, a minimally invasive, transcervically placed micro-insert that occludes the Fallopian tubes, resulting in permanent female contraception. Device under study: The Essure pbc implant is a dynamically expanding micro-insert which is placed in the proximal section of the Fallopian tube using a modified minimal access technology for cannulating the tube.

A laparoscopic surgical training and accreditation program up and running.

Beginning in March 1997, a training and accreditation program in laparoscopic surgery was established at our hospital according to the training guidelines provided by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) (1, 2). Registrars were accredited upon satisfactory completion of supervised surgery at each training level. Consultants seeking clinical privileges in advanced laparoscopic surgery were asked to submit a formal application.

Human chorionic gonadotropin as a predictor of outcome in assisted reproductive technology pregnancies.

Objective: To determine whether serum hCG and progesterone levels obtained 16 days after ovulation are reliable predictors of pregnancy outcome.

Design: A retrospective study.

Setting: The data were obtained from two integrated Adelaide-based clinics: the Queen Elizabeth Hospital and Wakefield Clinic.

The ethics of genetic research on sexual orientation.

Research into the genetic component of some complex behaviors often causes controversy, depending on the social meaning and significance of the behavior under study. Research into sexual orientation-simplistically referred to as "gay gene" research-is an example of research that provokes intense controversy. This research is worrisome for many reasons, including the fact that it has been used to harm lesbians and gay men.

Reduced pregnancy rates following the transfer of human embryos frozen or thawed in culture media supplemented with normal serum albumin.

Over a 26 month period 17% of couples having treatment in our clinical programmes selected a commercially available protein (normal serum albumin, NSA) prepared from pooled human sera instead of using their own serum as a supplement for their embryo culture media. In a retrospective analysis of >2000 gonadotrophin-stimulated cycles and 1000 cycles where frozen/thawed embryos were transferred, fertilization, embryo quality and pregnancy rates following in-vitro fertilization (IVF), gamete intra-Fallopian transfer (GIFT) or intracytoplasmic sperm injection (ICSI) were unaffected by the type of protein used to supplement the culture medium. When embryos were thawed in medium containing NSA, both pregnancy (PR) and implantation rates (IR) were significantly lower (P <0.

Falloposcopy: Antegrade Imaging in the Management of Oviductal Disease.

Salpingoscopy provides excellent views of the outer oviductal lumen, provided the fimbrial end is accessible laparoscopically. Falloposcopy is a less invasive approach through the uterine cavity. The technique is demanding and requires small flexible endoscopes with a reduced field of view and image quality.

New methods for transcervical cannulation of the fallopian tube.

Technological advances have led to major improvements in the design and application of Fallopian tube cannulation devices using the transcervical approach. Presently such cannulation systems are being used to overcome infertility disorders. These transcervical access systems are now able to displace debris that may block the tube, break down intraluminal adhesions or place egg, sperm or embryos in the tube to facilitate conception.
