STUDY QUESTION: Are meiotic and developmental competence of human oocytes from small (2-8 mm) antral follicles improved by applying an optimized IVM method involving a prematuration step in presence of C-Type Natriuretic Peptide (CNP) followed by a maturation step in presence of FSH and Amphiregulin (AREG)? SUMMARY ANSWER: A strategy involving prematuration culture (PMC) in the presence of CNP followed by IVM using FSH + AREG increases oocyte maturation potential leading to a higher availability of Day 3 embryos and good-quality blastocysts for single embryo transfer...

Defining thresholds of prognostic markers is essential for stratified medicine. Such thresholds are mostly estimated from purely statistical measures regardless of patient preferences potentially leading to unacceptable medical decisions. Quality-Adjusted Life-Years are a widely used preferences-based measure of health outcomes. We develop a time-dependent Quality-Adjusted Life-Years-based expected utility function for censored data that should be maximized to estimate an optimal threshold. We performed a simulation study to compare estimated thresholds when using the proposed expected utility approach and purely statistical estimators...

PURPOSE: Recently, guidelines on the annotation of dynamic human embryo monitoring recommended screening for the presence of planar blastomere arrangement at the 4-cell stage. This observational study was set up in order to analyze whether developmental kinetics of planar human embryos are different from tetrahedral ones. METHODS: Therefore, embryos of 115 consecutive ICSI patients (showing 32 planar and 554 tetrahedral embryos) were cultured in a new time-lapse system (Miri TL) and their embryos were annotated for morphokinetic development and screened for irregular cleavages and morphological dysmorphisms...

This study investigated the use of medroxyprogesterone acetate (MPA) or a short protocol for controlled ovarian hyperstimulation (COH) in patients with advanced endometriosis who have normal ovarian function, and to compare cycle characteristics and pregnancy outcomes after frozen-thawed embryo transfer (FET). This was a retrospective case-control study of 244 patients with advanced endometriosis undering COH. The patients were allocated to three groups: the surgery group with MPA COH (62 patients, 71 IVF/ICSI cycles, 78 FET cycles); the aspiration group with MPA COH (85 patients had ovarian "chocolate" cysts (>3 cm) aspirated, 90 IVF/ICSI cycles, 76 FET cycles); and the short protocol group (97 patients, 101 IVF/ICSI cycles, 51 FET cycles)...

Chad A Purnell, Elbert E Vaca, Marco F Ellis
BACKGROUND: Orbital exenteration is a significant reconstructive challenge for plastic surgeons. Options described for these defects range from healing by secondary intention to free tissue transfer. The authors present our preferred reconstruction of orbital defects with free forearm-based flaps, which provides quality soft tissue and orbital contouring in 1 stage to consistently allow placement of bone-anchored implants for eventual orbital prosthesis. METHODS: This conical shape of the orbit is deconstructed into a "Pac-Man" type shaped flap that leaves adequate depth for a prosthesis...

BACKGROUND: Early unplanned readmissions of "bouncebacks" to intensive care units are a healthcare quality metric and result in higher mortality and greater cost. Few studies have examined bouncebacks to the neurointensive care unit (neuro-ICU), and we sought to design and implement a quality improvement pilot to reduce that rate. METHODS: First, we performed a retrospective chart review of 504 transfers to identify potential bounceback risk factors. Risk factors were assessed on the day of transfer by the transferring physician identifying patients as "high risk" or "low risk" for bounceback...

Acephalic spermatozoa is a rare teratozoospermia associated with male infertility. However, the pathogenesis of this disorder remains unclear. Here, we report a 27-year-old infertile male from a consanguineous family, who presented with 99% headless sperm in his ejaculate. Electron microscopic and immunofluorescence analysis suggested breakage at the midpiece of the patient's sperm cells. Subsequent whole-exome sequencing (WES) analysis identified a homozygous deletion within TSGA10 (c.211delG; p.A71Hfs*12), which resulted in the production of truncated TSGA10 protein...

BACKGROUND: The relationship between fatigue-related risk and impaired clinical performance is not entirely clear. Non-technical factors represent an important component of clinical performance and may be sensitive to the effects of fatigue. The hypothesis was that the sum score of overall non-technical performance is degraded by fatigue. METHODS: Nineteen physicians undertook two different simulated air ambulance missions, once when rested, and once when fatigued (randomised crossover design)...

Atopic dermatitis (AD) is a chronic skin condition affecting children and adults, with a significant negative impact on patient and caregiver quality of life (QOL). Although effective treatments for AD are available, outcomes are often limited by poor adherence to treatment plans. Effective patient and caregiver education about the disease and its management is a necessary and important component of AD care. Therapeutic patient education (TPE) is a patient-centered process that aims to transfer information and skills necessary to manage and cope with a disease from health care professionals to patients and caregivers...

AIM: Ovarian aging, which leads to diminished ovarian reserve and decreased oocyte quality, is highly associated with poor reproductive outcomes. It has been suggested that dehydroepiandrosterone (DHEA) might be able to temporarily slow down the aging process. This study attempted to investigate the clinical benefits of DHEA in older patients and the anti-senescence effect of DHEA on cumulus cells (CC) and human ovarian granulosa cells (HO23 cell line). METHODS: This prospective study enrolled 88 patients who underwent in vitro fertilization (IVF), including 30 younger patients (aged ≤ 37 years) and 58 older patients (aged > 37 years)...

Multi-fraction cervical cancer brachytherapy is a form of image-guided radiotherapy that heavily relies on 3D imaging during treatment planning, delivery, and quality control. In this context, deformable image registration can increase the accuracy of dosimetric evaluations, provided that one can account for the uncertainties associated with the registration process. To enable such capability, we propose a mathematical framework that first estimates the registration uncertainty and subsequently propagates the effects of the computed uncertainties from the registration stage through to the visualizations, organ segmentations, and dosimetric evaluations...
