Purpose: Health anxiety (HA) is a critical issue for cancer patients. This study investigates the role of intolerance of uncertainty (IU) in HA among a heterogeneous sample of cancer patients, comparing those with hematological malignancies and solid tumor cancers. It also explores the impact of demographic and cancer-related factors on HA.
Methods: A total of 184 cancer patients participated in this study. Measurement model and structural model were assessed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to evaluate the reliability, validity, direct and indirect effect, explanatory power, and predictive power of constructs in the model. Multigroup analyses and moderation effects of demographic and cancer-related variables were also examined.
Results: IU significantly predicted HA, mediated by negative problem orientation (NPO) and positive beliefs about worry (PBW). females scored higher in HA, NPO, and cognitive avoidance (CA), while males scored higher in PBW. Solid tumor patients exhibited a stronger positive relationship between IU and HA than hematological malignancy patients. Age and marital status also affected the relationships between IU, NPO, and PBW. Patients without a history of chronic illness or COVID displayed stronger associations between IU and NPO.
Conclusion: IU is a key predictor of HA in cancer patients, with varying impacts across demographic and clinical groups. Tailored interventions addressing IU and related constructs help reduce HA, especially among patients with solid tumor cancers, female, married, older, lower educated, and newly diagnosed without former disease diagnosis. This study emphasizes the importance of considering patient heterogeneity in psychological interventions for HA.

Background And Hypothesis: Unlike X-linked or autosomal recessive Alport Syndrome, no clear genotype/phenotype correlation has yet been demonstrated in patients carrying a single variant of COL4A3 or COL4A4.
Methods: We carried out a multicenter retrospective study to assess the risk factors involved in renal survival in patients presenting a single pathogenic variant on COL4A3 or COL4A4.
Results: 97 patients presenting a single pathogenic variant of COL4A3 or COL4A4 were included.
Feasibility and preliminary efficacy of a physical activity intervention in adults with lymphoma undergoing treatment.
Pilot Feasibility Stud
January 2025
Department of Internal Medicine - Cardiology, Virginia Commonwealth University, West Hospital 8th Floor, North Wing, Richmond, VA, 23298, USA.
Background: To determine the feasibility, acceptability, and preliminary efficacy of a 6-month tailored non-linear progressive physical activity intervention (PAI) for lymphoma patients undergoing chemotherapy.
Methods: Patients newly diagnosed with lymphoma (non-Hodgkin (NHL) or Hodgkin (HL)) were randomized into the PAI or healthy living intervention (HLI) control (2:1). Feasibility was assessed by examining accrual, adherence, and retention rates.
Deproteinized Bovine Bone Mineral With Collagen for Anterior Maxillary Ridge Augmentation: A Retrospective Cohort Study.
Clin Implant Dent Relat Res

Department of Implantology, The Affiliated Hospital of Stomatology, School of Stomatology, Zhejiang University School of Medicine, Hangzhou, China.
Objectives: This study aimed to assess the effects of deproteinized bovine bone mineral with collagen (DBBMC) combined with deproteinized bovine bone mineral (DBBM) on facial alveolar bone augmentation in the anterior maxillary region.
Materials And Methods: Patients receiving dental implant placement with simultaneous lateral bone augmentation using DBBM (control group) or DBBMC combined with DBBM (test group) were included in the study. The radiographic assessment of facial alveolar bone, such as facial horizontal bone thickness (FHBT), facial vertical bone level (FVBL), and square of facial bone (SFB), was taken by cone beam computed tomography (CBCT).

Department of Surgery, Amsterdam UMC Location Vrije Universiteit Amsterdam, De Boelelaan 1117, Amsterdam, the Netherlands.
Background: Current diagnostic imaging modalities have limited ability to differentiate between malignant and benign pancreaticobiliary disease, and lack accuracy in detecting lymph node metastases. F-Prostate-Specific Membrane Antigen (PSMA) PET/CT is an imaging modality used for staging of prostate cancer, but has incidentally also identified PSMA-avid pancreatic lesions, histologically characterized as pancreatic ductal adenocarcinoma (PDAC). This phase I/II study aimed to assess the feasibility of F-PSMA PET/CT to detect PDAC.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with limited treatment options and a poor prognosis. The critical role of epigenetic alterations such as changes in DNA methylation, histones modifications, and chromatin remodeling, in pancreatic tumors progression is becoming increasingly recognized. Moreover, in PDAC these aberrant epigenetic mechanisms can also limit therapy efficacy.
