Introduction: There is a lack of consensus on the optimal surgical strategy for differentiated thyroid cancer (DTC), partly due to inconsistent reporting of outcomes. This limits the ability to compare study results, hindering the ability to draw conclusions regarding novel treatment strategies. The development of a core outcome set (COS) reduces heterogeneity in the selection and reporting of clinical trial outcomes.

Department of Radiation Oncology, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands. Electronic address:

Background: Neoadjuvant chemoradiotherapy (nCRT) followed by surgical resection is the current standard of care for oesophageal cancer (EC) patients. This treatment is associated with a variety of complications, with pneumonia being the most common. We hypothesize that proton radiotherapy (PRT) can significantly reduce the incidence of pneumonia compared to photon radiotherapy (PhRT).

Background/objective: Raloxifene, a selective estrogen receptor modulator (SERM), may improve symptoms and cognition in schizophrenia spectrum disorders (SSD). Studies have shown inconsistent efficacy, especially in men with SSD. We assessed whether single nucleotide polymorphisms (SNPs) on genes involved in the pharmacodynamics (ESR1 and COMT) and pharmacokinetics (UGT1A8) of raloxifene can explain the heterogeneous treatment response to raloxifene augmentation in patients with SSD.

Phagocytosis by macrophages decreases the radiance of bioluminescent Staphylococcus aureus.

BMC Microbiol

January 2025

Department of Biomaterials and Biomedical Technology, University Medical Center Groningen, Antonius Deusinglaan 1, Groningen, The Netherlands.

Article Synopsis
  • The study investigates how the bioluminescence of Staphylococcus aureus changes when it is engulfed by macrophages, showing a reduction in light production compared to bacteria in culture.
  • The bacterial count remains stable during this process, but bioluminescence increases again when bacteria are released after macrophage cell death or when fresh macrophages are added.
  • These findings highlight the need to consider intracellular residency effects on bioluminescence when using imaging techniques to study infections in live animals.

The potential of large language models (LLMs) in medical applications is significant, and Retrieval-augmented generation (RAG) can address the weaknesses of these models in terms of data transparency and scientific accuracy by incorporating current scientific knowledge into responses. In this study, RAG and GPT-4 by OpenAI were applied to develop GuideGPT, a context aware chatbot integrated with a knowledge database from 449 scientific publications designed to provide answers on the prevention, diagnosis, and treatment of medication-related osteonecrosis of the jaw (MRONJ). A comparison was made with a generic LLM ("PureGPT") across 30 MRONJ-related questions.

Gut microbiome dysbiosis is not associated with portal vein thrombosis in patients with end-stage liver disease: a cross-sectional study.

J Thromb Haemost

January 2025

University of Groningen, Department of Surgery, Section of Hepatobiliary Surgery and Liver Transplantation, University Medical Center Groningen, Groningen, the Netherlands. Electronic address:

Background: Portal vein thrombosis (PVT) is a common complication in patients with end-stage liver disease (ESLD). The portal vein in ESLD patients is proposedly an inflammatory vascular bed due to translocation of endotoxins and cytokines from the gut. We hypothesized that a pro-inflammatory gut microbiome and elevated trimethylamine N-oxide (TMAO), a driver of thrombosis, may contribute to PVT development.

Objective: Cross-sectional network studies find mixed results regarding changes in network structure as a response to treatment across disorders. This study characterized improvement in mental health following Cognitive Processing Therapy (CPT) for PTSD in veterans from the perspective of network psychometrics and explored how cross-sectional networks inform our understanding of PTSD recovery.

Methods: Veterans with PTSD participated in CPT-based intensive treatment programs (ITPs), offered in two-week (N = 635) or three-week (N = 457) formats.

Purpose: A prospective longitudinal cohort study was performed to gain insight into the course of recovery in terms of pain, opioid consumption, and mobility in patients with a lateral compression (LC) pelvic injury.

Methods: Adult patients with an LC injury, without any cognitive disorders or limited mobility and who could communicate in Dutch were asked to participate. Pain in terms of NRS (numeric rating scale, range 0-10), opioid use and mobility were recorded at eight time points: at hospital admission, and three days, one week, six weeks, three months, six months, one year and two years after the injury.

Pregnant women with congenital heart disease carry a high risk of complications, especially when cardiac function is suboptimal. Increasing evidence suggests that impaired right ventricular (RV) function has a negative effect on placental function, possibly through venous congestion. We report a case series of hepatic and renal venous flow patterns in pregnant women with right ventricular dysfunction after repaired Tetralogy of Fallot (ToF), relative to those observed in normal pregnancy and preeclampsia.

Background: Micronutrient deficiencies are common and play a significant role in the prognosis of many chronic diseases, including heart failure (HF), but their prevalence in HF is not well known. As studies have traditionally focused on causes originating within the intestines, exocrine pancreatic insufficiency (EPI) has been overlooked as a potential contributor. The exocrine pancreas enables the absorption of various (fat-soluble) micronutrients and may be insufficient in HF.

Background: Higher than standard doses of rifampicin could improve the treatment outcome of drug-susceptible tuberculosis without compromising the safety of patients.

Methods: We performed a systematic review of prospective clinical studies including adults with pulmonary and extrapulmonary TB receiving rifampicin doses above 10mg/kg/day. We extracted the data on overall adverse events (AE), hepatic AE, sputum culture conversion (SCC) at week 8, recurrence, mortality, and pharmacokinetics.

Purpose To validate a deep learning (DL) model for predicting the risk of prostate cancer (PCa) progression based on MRI and clinical parameters and compare it with established models. Materials and Methods This retrospective study included 1607 MRI scans of 1143 male patients (median age, 64 years; IQR, 59-68 years) undergoing MRI for suspicion of clinically significant PCa (csPCa) (International Society of Urological Pathology grade > 1) between January 2012 and May 2022 who were negative for csPCa at baseline MRI. A DL model was developed using baseline MRI and clinical parameters (age, prostate-specific antigen [PSA] level, PSA density, and prostate volume) to predict the time to PCa progression (defined as csPCa diagnosis at follow-up).
