Considerations to forgo systemic treatment in patients with advanced esophageal or gastric cancer: A real-world evidence study.

The majority of patients with advanced esophageal or gastric cancer do not start palliative systemic treatment. To gain insight into the considerations underlying the decision not to start systemic treatment, we analyzed characteristics of patients starting and not starting systemic treatment, reasons for not starting systemic treatment, and receipt of local palliative treatments on a nationwide scale. Patients diagnosed with advanced esophageal or gastric cancer between 2015 and 2021 were included (n = 10,948).

Using Vital Signs for the Early Prediction of Necrotizing Enterocolitis in Preterm Neonates with Machine Learning.

Background/objectives: Necrotizing enterocolitis (NEC), a devastating neonatal gastrointestinal disease mostly seen in preterm infants, lacks accurate prediction despite known risk factors. This hinders the possibility of applying targeted preventive therapies. This study explores the use of vital signs, including cerebral and splanchnic oxygenation, measured with near-infrared spectroscopy in early NEC prediction.

Development of a parent decision support tool for surgical necrotising enterocolitis: a study protocol.

Introduction: Necrotising enterocolitis is a devastating gastrointestinal disease predominantly affecting preterm infants. In 40% of cases, its rapid progression renders conservative treatment insufficient, necessitating laparotomy as the sole viable option for survival. However, high perioperative and postoperative mortality rates, along with severe future potential disabilities and suffering, can complicate the decision of whether surgery is still in the infant's best interest.

Feasibility of Non-Invasive Sentinel Lymph Node Identification in Early-Stage NSCLC Through Ultrasound Guided Intra-Tumoral Injection of Tc-Nanocolloid and Iodinated Contrast Agent During Navigation Bronchoscopy.

: As the first sentinel lymph nodes (SLN) in lung cancer are most likely to harbor metastasis, their non-invasive identification could have a significant role in future treatments. We investigated the feasibility of adding an SLN procedure to a diagnostic navigation bronchoscopy. : Thirty-one patients were included for injection of Tc-nanocolloid and an iodinated contrast agent intra-/peritumorally and assessment of tracer dissipation via SPECT and CBCT imaging.

Patient access to perioperative chemotherapy with fluorouracil, leucovorin, oxaliplatin and docetaxel in patients with resectable gastric cancer in the Netherlands.

Background: The FLOT4 trial demonstrated superior survival of perioperative chemotherapy with 5-fluorouracil, oxaliplatin, and docetaxel (FLOT) compared to anthracycline triplets for resectable gastric cancer. These results were presented at the American Society of Clinical Oncology (ASCO) congress in June 2017 and published in April 2019. However, adoption of novel treatments in clinical practice often encounters delays.

Methods: Patients from the D1/D2 study or the CRITICS trial were included in exploratory surgery-alone (SAtest) or chemotherapy test (CTtest) cohorts.

Concept design overview: a question of choices and compromise.

The Spherical Tokamak for Energy Production (STEP) programme hypothesizes that a compact machine offers a route to reduced capital cost that directly tackles the barrier to entry of this potentially transformative technology. History has shown that with an unsolved, complex and highly interdependent design challenge, there is a need to balance exploration of the problem with progress. Almost all complex systems arise from the evolutionary improvement of simpler systems which is an approach the programme has adopted by working through a virtual natural selection of design families towards a single concept consistent with the initiating hypothesis.

The clinical implications of staging laparoscopy in the diagnostic workup of gastric cancer patients: A population based study.

Background: Since 2016, staging laparoscopy has been implemented in the diagnostic workup of patients with gastric cancer. Staging laparoscopy aims to detect incurable disease (peritoneal metastases and irresectable tumors) and to prevent futile laparotomies.

Methods: In this population-based nationwide study, we sought patient- and tumor characteristics associated with undergoing a staging laparoscopy.

Systemic Treatment Strategies and Outcomes of Patients With Synchronous Peritoneal Metastases of Gastric Origin: A Nationwide Population-Based Study.

Background: Palliative systemic treatment is currently standard of care for metastatic gastric cancer. However, patients with peritoneal metastases of gastric origin are often underrepresented in clinical studies due to unmeasurable radiologic disease. This study describes the systemic treatment strategies and outcomes in patients with peritoneal metastases in a nationwide real-world setting.

Materials And Methods: First, phantom experiments were performed to assess the algorithm, using the Xsight lung phantom with custom inserts containing straight or curved catheters. During scanning, the inserts moved in a continuous sinusoidal or breath-hold mimicking pattern, with varying amplitudes and frequencies.

Use of Domain Labels during Pre-Training for Domain-Independent WiFi-CSI Gesture Recognition.

To minimize dependency on the availability of data labels, some WiFi-CSI based-gesture recognition solutions utilize an unsupervised representation learning phase prior to fine-tuning downstream task classifiers. In this case, however, the overall performance of the solution is negatively affected by domain factors present in the WiFi-CSI data used by the pre-training models. To reduce this negative effect, we propose an integration of the adversarial domain classifier in the pre-training phase.
