Article Synopsis
  • Palmar or plantar fibromatosis is a benign condition that can impair hand or foot function, and while surgery is common, radiation therapy (RT) can also be effective in managing symptoms.
  • A study involved three patients receiving RT for fibromatosis, using custom-designed 3D-printed boluses created from CT imaging to enhance treatment effectiveness.
  • The results showed the printed boluses had very minimal shape deviations, good density accuracy, and no significant issues during treatment, indicating that 3D printing could improve RT dosimetry for this condition.

The purpose of this study was to investigate the perceived symbol referent relationship for selected symbols in typical adults for two different symbol sets: Indian Picture Symbols for Communication (IPSC) and Picture Communication Symbols (PCS) to identify cultural influences on symbol recognition. A total of 240 typical adults, including 120 nonprofessionals, and 120 health professionals, from Kerala, a southern state in India, participated in the study. A guessability task involving IPSC and PCS symbols for 30 target referents was utilized.

Purpose: The purpose of this study is to investigate the effectiveness of an augmentative and alternative communication (AAC) intervention package consisting of systematic instruction and aided modeling with speech-output technologies on the acquisition, maintenance, and generalization of socio-communicative behaviors-initiating a request for a turn, answering questions, and commenting-in four, minimally speaking (MS) autistic children between the ages of 6 and 9 years.

Method: A multiple-probe design across behaviors replicated across participants was implemented to evaluate the effects of systematic instruction and aided modeling on initiating requests for a turn, answering questions, and commenting behaviors. Additionally, a pre- and posttreatment multiple-generalization-probes design was used to assess generalization across peers.

Background: Radiotherapy delivery regimens can vary between a single fraction (SF) and multiple fractions (MF) given daily for up to several weeks depending on the location of the cancer or metastases. With limited evidence comparing fractionation regimens for oligometastases, there is support to explore toxicity levels to nearby organs at risk as a primary outcome while using SF and MF stereotactic ablative radiotherapy (SABR) as well as explore differences in patient-reported quality of life and experience.

Methods: This study will randomize 598 patients in a 1:1 ratio between the standard arm (MF SABR) and the experimental arm (SF SABR).

Acid attack is a form of violent assault involving the act of throwing acid or any corrosive substance such as sulfuric acid, nitric acid, and hydrochloric acid with the intention to disfigure, maim, torture, or kill. A combination of surgical intervention along with prosthetic management using maxillofacial prosthesis serves a good treatment modality for rehabilitation in such cases. The advent of technological advancements has made the rehabilitation procedure easier, faster, and comfortable both for the patient and prosthodontist.

  • Social determinants of health (SDoH) significantly influence health outcomes, and this study explored how the COVID-19 pandemic affected SDoH among patients in an urban emergency department (ED).
  • A screening method revealed that a majority of patients experienced adverse SDoH, particularly in areas like education, food security, and employment, with over half reporting pandemic-related impacts.
  • Follow-up surveys showed that while many patients attempted to use resources, barriers such as time constraints and forgetfulness hindered their success, highlighting a preference for printed and mobile-based resource guides.
