IPEM topical report: guidance on 3D printing in radiotherapy.

There has been an increase in the availability and utilization of commercially available 3D printers in radiotherapy, with applications in phantoms, brachytherapy applicators, bolus, compensators, and immobilization devices. Additive manufacturing in the form of 3D printing has the advantage of rapid production of personalized patient specific prints or customized phantoms within a short timeframe. One of the barriers to uptake has been the lack of guidance.

Assessing Obstetrics and Gynecology (OBGYN) Clinicians' Knowledge, Practice, and Attitudes toward Anorexia Nervosa, Atypical Anorexia Nervosa, and Amenorrhea.

Study Objective: Anorexia nervosa (AN) and atypical anorexia nervosa (AAN) are eating disorders (EDs) characterized by extreme restriction of energy intake. However, in contrast to AN, those with AAN are not underweight. Although individuals with either AN or AAN can experience associated functional hypothalamic amenorrhea (FHA) that may prompt them to seek gynecological care, little is known about OBGYNs' knowledge and approach to these patients; this study sought to fill this gap.

The Validity of Radiographic Measurements Compared to 3D-surface Model-Based Measurements in Shoulders with Reverse Total Shoulder Arthroplasty.

Background: Postoperative assessment following reverse total shoulder arthroplasty (rTSA) typically involves plain radiographs to evaluate implant positioning parameters, such as humeral distalization and lateralization along with medialization and distalization of the center of rotation (COR). However, the precision of these radiographic measurements remains unclear. This study aimed to validate the accuracy of radiographic two-dimensional (2D) measurements compared to three-dimensional (3D) surface model-based measurements derived from CT data for evaluating postoperative parameters in rTSA.

Regional Anesthesia and Surgical Volume in Children Undergoing Nuss Repair: A Multicenter Review.

Introduction: Regional anesthetic approach and surgical volume have been shown to outcomes in patients undergoing Nuss procedure for pectus excavatum. However, their independent relationship is not described. We investigated how regional anesthesia and surgical volume are associated with length of stay (LOS), postoperative opioid use, operating room utilization, and complications.

Clinical and genetic characterization of a progressive RBL2-associated neurodevelopmental disorder.

Retinoblastoma (RB) proteins are highly conserved transcriptional regulators that play important roles during development by regulating cell-cycle gene expression. RBL2 dysfunction has been linked to a severe neurodevelopmental disorder. However, to date, clinical features have only been described in six individuals carrying five biallelic predicted loss of function (pLOF) variants.
