Background: Inadequate glycemic control in patients with type 2 diabetes (T2DM) is a major public health problem and a significant risk factor for the progression of diabetic complications.

Aim: To evaluate the effects of intensive and supportive glycemic management strategies over a 12-month period in individuals with T2DM with glycated hemoglobin (HbA1c) ≥ 10% and varying backgrounds of glycemic control.

Methods: This prospective observational study investigated glycemic control in patients with poorly controlled T2DM over 12 months.

Introduction: This study aimed to assess the detection rate of prostate cancer recurrence by prostate-specific member antigen positron emission tomography/computed tomography (PSMA PET/CT) with F-DCFPyL in patients with residual disease or biochemical recurrence (BCR), and its association with surgical pathology and prostate-specific antigen (PSA) kinetics.

Methods: Men from South Central Ontario enrolled in the PSMA Registry for Recurrent Prostate cancer (PREP) between April 2019 and December 2021 after radical prostatectomy (RP) and who had 1) pathologic stage N1 or persistent elevated PSA; or 2) BCR (PSA >0.10 ng/mL) where initial postoperative PSA was undetectable were included.

Article Synopsis
  • A study assessed the outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) who underwent different types of pancreatic surgeries between 2011 and 2023, including non-vascular resection (NVR), venous resection (VR), and arterial resection (AR).
  • Findings revealed that while initial disease stage did not impact median time to recurrence (TTR) or overall survival (OS), patients who had VR experienced significantly shorter TTR and OS compared to those with NVR and AR.
  • The use of chemotherapy or chemoradiation was found to enhance both TTR and OS, while AR was linked to higher 90-day mortality rates, emphasizing the importance of careful patient selection for this procedure

Low Earth Orbit (LEO) has emerged as a unique environment for evaluating altered stem cell properties in microgravity. LEO has become increasingly accessible for research and development due to progress in private spaceflight. Axiom Mission 2 (Ax-2) was launched as the second all-private astronaut mission to the International Space Station (ISS).

Article Synopsis
  • Microglia, although typically known for their immune functions in the central nervous system, also play crucial roles in brain development that are not yet fully understood, especially in humans.
  • Researchers used human microglia-like cells with a deleted MECP2 gene to study its impact, discovering that this disruption led to significant issues in cell functions like phagocytosis and synapse formation.
  • A drug called ADH-503 was found to enhance phagocytosis and restore normal synapse formation, offering potential new treatment options for conditions linked to MECP2 abnormalities in mice.

Aplastic anemia is a rare and heterogeneous disease that causes pancytopenia and aplasia of the bone marrow. It is characterized by a failure of hematopoiesis. It is believed that approximately 65% of cases of acquired aplastic anemia are idiopathic.

Recent findings from studies involving astronauts and animal models indicate that microgravity increases immune cell activity and potentially alters the white and gray matter of the central nervous system (CNS). To further investigate the impact of microgravity on CNS cells, we established cultures of three-dimensional neural organoids containing isogenic microglia, the brain's resident immune cells, and sent them onboard the International Space Station. When using induced pluripotent stem cell (iPSC) lines from individuals affected by neuroinflammatory and neurodegenerative diseases such as multiple sclerosis (MS) and Parkinson's disease (PD), these cultures can provide novel insights into pathogenic pathways that may be exacerbated by microgravity.

The feet are complex structures that transmit loads transferred by other parts of the body to the ground and are involved in many static and dynamic activities, such as standing and walking. The contact area and pressure changes between the feet and the ground surface can be measured using pedobarographic devices. With pedobarographic examinations, it is possible to obtain a wide range of information needed to support clinical evaluation and diagnostic tests in physical medicine and rehabilitation practice.

Objective: This study aimed to investigate the effects of central sensitization (CS) on pain sensitivity, disease activity, neuropathic symptoms and quality of life (QoL) in patients with rheumatoid arthritis (RA).

Methods: Sixty patients diagnosed with RA according to the American College of Rheumatology and the European League Against Rheumatism (ACR/EULAR) 2010 classification criteria were included in the study. Patient assessment tools included visual analog scale (VAS) for pain, algometer for pain pressure threshold (PPT), disease activity score in 28 joints (DAS-28) for disease activity (DA), central sensitization inventory (CSI) for CS and rheumatoid arthritis QoL questionnaire for QoL.

In-space manufacturing of nanomaterials is a promising concept while having limited successful examples. DNA-inspired Janus base nanomaterials (JBNs), used for therapeutics delivery and tissue regeneration, are fabricated via a controlled self-assembly process in water at ambient temperature, making them highly suitable for in-space manufacturing. For the first time, we designed and accomplished the production of JBNs on orbit during the Axiom-2 (Ax-2) mission demonstrating great promising and benefits of in-space manufacturing of nanomaterials.

Background: Patient-reported outcomes measures (PROM) are self-reflections of an individual's physical functioning and emotional well-being. The Edmonton Symptom Assessment Scale (ESAS) is a simple and validated PRO tool of 10 common symptoms and a patient-reported functional status (PRFS) measure. The prognostic value of this tool is unknown in patients with gastroesophageal cancer (GEC).

This exploratory study is a follow up to our previous investigation of immune response in the circulation of high-grade Gleason 9 prostate cancer patients treated with EBRT + BT compared to EBRT alone. Notably, EBRT + BT demonstrates the potential to elicit an effect on CD4/CD8 ratio which may have attributed to improved clinical response to therapy. Our findings show promise for leveraging circulating immune cells as predictive biomarkers for radiotherapy response.

Three Prime Repair Exonuclease 1 (TREX1) gene mutations have been associated with Aicardi-Goutières Syndrome (AGS) - a rare, severe pediatric autoimmune disorder that primarily affects the brain and has a poorly understood etiology. Microglia are brain-resident macrophages indispensable for brain development and implicated in multiple neuroinflammatory diseases. However, the role of TREX1 - a DNase that cleaves cytosolic nucleic acids, preventing viral- and autoimmune-related inflammatory responses - in microglia biology remains to be elucidated.

Patients with type 2 diabetes who have HbA1c values ≥ 10% have different previous glycemic trends, including new diagnosis of diabetes. We aimed to assess the efficacy of 3 months of intensive and facilitated antihyperglycemic treatment in patients with different glycemic backgrounds. In this observational study, patients with type 2 diabetes and poor glycemic control (indicated by an HbA1c level of > = 10%) were divided into groups based on their previous HbA1c levels (group 1; newly diagnosed type 2 diabetics, group 2; patients with previously controlled but now deteriorated HbA1c levels, group 3; patients whose HbA1c was not previously in the target range but was now above 10%, and group 4; patients whose HbA1c was above 10% from the start).
