Background: Thrombopoietin receptor agonists (TPO-RAs) have demonstrated efficacy in treating clinically significant thrombocytopenia, including chemotherapy-induced thrombocytopenia in adults. However, data regarding their safety and efficacy in pediatric, adolescents, and young adult (AYA) patients with hematologic malignancies are limited.

Methods: We retrospectively identified 15 pediatric and AYA patients aged 25 years or younger with hematologic malignancies treated with a TPO-RA at UCSF Benioff Children's Hospitals between 2015 and 2023.

Article Synopsis
  • Drug toxicity, particularly from non-steroidal anti-inflammatory drugs like diclofenac, contributes to chronic liver damage and disrupts bone health by affecting the liver-bone axis.
  • Researchers developed a reliable in vitro liver-bone co-culture model to study the effects of diclofenac on bone and liver interactions, finding optimal culture conditions for both systems.
  • The study revealed that chronic exposure to diclofenac enhances osteoclast-like cell activity in the co-culture, leading to reduced mineral content and stiffness in bone scaffolds, driven by oxidative stress and inflammation rather than diclofenac’s main metabolic products.

In the Anglo-American world the field of surgeon well-being is already very prominent, while in Germany it is still underrepresented. In this article, we aim to analyze the challenges and factors that affect the well-being of surgeons, including stress, burnout, workload, job satisfaction, autonomy, leadership, teamwork and work-life integration. Additionally, we discuss the connection between surgeon well-being and the shortage of new talent in surgery, which is currently being exacerbated by increasing treatment and physician demands, the age development of specialists and an overall high turnover.

Article Synopsis
  • - Phosphonates like EDTMP and ATMP are widely used in water treatment and household products, with their use increasing despite environmental concerns.
  • - A new bacterial strain, isolated from a washing machine biofilm, was studied for its ability to biodegrade these phosphonates; it showed susceptibility to certain antibiotics and could convert specific compounds, linking it to other similar strains.
  • - The strain effectively degrades ATMP and EDTMP but not glyphosate or AMPA, with gene analysis suggesting it possesses specific enzymes associated with phosphonate degradation.

In this work we demonstrate the first laboratory study results of lens fragmentation with low-energy picosecond ultrashort laser pulses after artificial induction of cataract with microwave radiation on an ex vivo animal model. This method will be evaluated with regard to the further development of lens fragmentation with novel ultrashort picosecond laser systems instead of ultrasonic phacoemulsification or the significantly more complex femtosecond laser fragmentation. As samples we used postmortem porcine eyes.

Background And Purpose: The aim was to determine the value of autologous haematopoietic stem cell transplantation (aHSCT) as a therapeutic intervention for progressive multiple sclerosis (PMS) based on a systematic review of the current literature.

Methods: All studies from the databases PubMed and Google Scholar published in English before February 2024 which provided individual data for PMS patients were systematically reviewed. PICO was defined as population (P), primary progressive MS and secondary progressive MS patients; intervention (I), treatment with aHSCT; comparison (C), none, disease-modifying therapy treated/relapsing-remitting MS cohorts if available; outcome (O), transplant-related mortality, progression-free survival (PFS) and no evidence of disease activity.

Mutations in the cohesin complex components (STAG2, RAD21, SMC1A, SMC3, and PDS5B) are recurrent genetic drivers in myelodysplastic neoplasm (MDS) and acute myeloid leukemia (AML). Whether the different cohesin subunit mutations share clinical characteristics and prognostic significance is not known. We analyzed 790 cohesin-mutant patients from the Dana-Farber Cancer Institute (DFCI) and the Munich Leukemia Laboratory (MLL), 390 of which had available outcome data, and identified subunit-specific clinical, prognostic, and genetic characteristics suggestive of distinct ontogenies.

Article Synopsis
  • The study explores the factors influencing fracture healing and uses simulation-based workflows to predict potential non-unions in patients.
  • It introduces a new patient-specific simulation tool that integrates clinical data to assess fracture healing, applying it to two cases of non-union post-fracture fixation.
  • The results showcased the simulation's effectiveness in predicting non-unions but highlighted a discrepancy in healing rates that necessitates further validation for improved accuracy, especially for biologically complex cases.

The diagnosis and treatment of non-unions still represents an interdisciplinary challenge. Therefore, prevention, early detection and specific treatment are of great importance. Non-unions of the upper extremities, although less common than that of the lower extremities, requires special attention for successful treatment due to the central role of the shoulder girdle and arm in day to day activities.

Venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism, is a life-threatening, costly, and common preventable complication associated with hospitalization. Although VTE prevention strategies such as risk assessment and prophylaxis are available, they are not applied uniformly or systematically across US hospitals and healthcare systems. Hospital-level performance measurement has been used nationally to promote standardized approaches for VTE prevention and incentivize the adoption of guideline-based care management.

The elderly exhibit a reduced healing capacity after fracture, which is often associated with delayed or failed bone healing. This is due to a plethora of factors, such as an impaired bone vascular system and delayed angiogenesis. The phosphodiesterase-5 (PDE-5) inhibitor sildenafil exerts pro-angiogenic and pro-osteogenic effects.

Electrodermal activity (EDA) is considered a standard marker of sympathetic activity. However, traditional EDA measurement requires electrodes in steady contact with the skin. Can sympathetic arousal be measured using only an optical sensor, such as an RGB camera? This paper presents a novel approach to infer sympathetic arousal by measuring the peripheral blood flow on the face or hand optically.
