Glycogen storage disease type III (GSD III) is a rare metabolic disorder characterized by a deficiency of liver and muscle amylo-1,6-glucosidase. This condition presents with severe hepatic symptoms in childhood, mostly hepatomegaly, hypoglycemia in half of patients, while muscular complications may predominate in adulthood. Hepatic fibrosis, cirrhosis and hepatocellular carcinoma (HCC) are common complications in older patients.

Objective: Black/African American women with breast cancer have disproportionately higher mortality rates and report experiencing a lower quality of life during survivorship compared to non-Hispanic white women. Despite support for the integration of peer navigation in cancer care and survivorship to address these inequities, Black/African American women often have limited access to culturally tailored peer navigation programs. We aimed to investigate the unique needs and strengths of Black/African American women with breast cancer and survivors to inform the development of a culturally tailored peer navigation program for Black/African American women.

Background/objectives: We assessed the influence of local patients and clinical characteristics on the performance of commercial deep learning (DL) segmentation models for head-and-neck (HN), breast, and prostate cancers.

Methods: Clinical computed tomography (CT) scans and clinically approved contours of 210 patients (53 HN, 49 left breast, 55 right breast, and 53 prostate cancer) were used to train and validate segmentation models integrated within a vendor-supplied DL training toolkit and to assess the performance of both vendor-pretrained and custom-trained models. Four custom models (HN, left breast, right breast, and prostate) were trained and validated with 30 (training)/5 (validation) HN, 34/5 left breast, 39/5 right breast, and 30/5 prostate patients to auto-segment a total of 24 organs at risk (OARs).

Sleep is an essential behavior that supports lifelong brain health and cognition. Neuronal synapses are a major target for restorative sleep function and a locus of dysfunction in response to sleep deprivation (SD). Synapse density is highly dynamic during development, becoming stabilized with maturation to adulthood, suggesting sleep exerts distinct synaptic functions between development and adulthood.

Summary: The resistance to thyroid hormone syndrome (RTHβ) occurs uncommonly and requires a high level of clinical suspicion and specific investigations to reach a precise diagnosis and to avoid unnecessary and potentially harmful therapies. We report a case of a young male patient referred to our unit for SARS-CoV-2 infection and atrial fibrillation with elevated thyroid hormones and non-suppressed thyroid-stimulating hormone (TSH), for which antithyroid therapy was prescribed. A mood disorder was reported in the medical history.

Background: Understanding professionalism is an essential component of becoming a doctor in order to ensure the trust of patients and wider society. Integrally linked to the concept of professionalism is the importance of identifying and raising concerns to ensure high quality, safe patient care. It is recognised that medical students are uniquely placed to identify and report concerns given their frequent rotations through multiple clinical placements and their peer relationships and, in so doing, develop and enact their own medical professionalism.

The "hidden curriculum" in medical school includes a stressful work environment, un-empathic role models, and prioritisation of biomedical knowledge. It can provoke anxiety and cause medical students to adapt by becoming cynical, distanced and less empathic. Lower empathy, in turn, has been shown to harm patients as well as practitioners.

Article Synopsis
  • This study focused on using CT imaging alone for defining treatment areas in palliative radiotherapy for head and neck cancer, as many clinics lack access to advanced imaging like MRI or PET scans.
  • Researchers analyzed two datasets of CT scans (one with contrast and one without) and utilized an advanced auto-segmentation method (nnU-Net) to determine tumor boundaries through five different strategies.
  • Results showed reasonable accuracy in automatically outlining treatment areas, although substantial corrections would be needed before these methods could be applied in real clinical settings.
