Background: Previous studies have shown that prostaglandins (PGs) dramatically stimulate healing processes in bone. However, the effect of prostaglandin I2 (PGI2) on fracture healing remains unclear. To investigate the effect of PGI2, a study on fracture healing process in closed tibia fractures was designed.
Methods: Thirty-six Sprague-Dawley male rats were randomized into two groups. On the first day, their right tibias were fractured by three-point bending technique. The study group (n = 18) received a single injection of 10 µg/kg iloprost for 5 days, while the control group (n = 18) received saline solution in the same way. On the 7th, 14th and 28th days following the fracture, six rats were sacrificed and their right legs were harvested in each group. The progression of fracture healing was assessed for each specimen by the scores of radiography (by Lane-Sandhu) and histology (by Huo et al).
Results: On the 7th day, the radiographic and histologic scores were equal. On the 14th day radiographic total score was 6 and histologic total score was 23 in the iloprost group, whereas radiographic total score was 11 and histologic total score was 33 in the control group. On the 14th day radiographic and histologic scores were significantly decreased in the iloprost group compared to the control group (P < 0.05). On the 28th day radiographic total score was 12 and histologic total score was 37 in the iloprost group, whereas radiographic total score was 15 and histologic total score was 40 in the control group. On the 28th day although there was a decrease in radiographic and histologic scores of the iloprost group acording to control group, it was not statistically significant (P > 0.05).
Conclusion: Iloprost delays fracture healing in early stage in rats.

Importance: Cutaneous chronic graft-vs-host disease (GVHD) is independently associated with morbidity and mortality after allogeneic hematopoietic cell transplant. However, the health-related quality-of-life (HRQOL) domains that are most important to patients are poorly understood.
Objective: To perform a concept elicitation study to define HRQOL in cutaneous chronic GVHD from the patient perspective and to compare experiences of patients with epidermal vs sclerotic disease.

Objectives: Antegrade wiring (AW) is the most common coronary chronic total occlusion (CTO) crossing strategy and usually relies upon stepwise guidewire escalation starting from the low tip-load polymer-jacketed wire (standard guidewire escalation). The authors aimed to investigate whether the upfront use of intermediate tip-load polymer-jacketed guidewire translates into improved procedural outcomes of CTO percutaneous coronary intervention (PCI).
Methods: The Gladius First trial was a single-center, investigator-initiated, randomized, prospective trial.

Importance: Obsessive-compulsive and related disorders (OCRDs) encompass various neuropsychiatric conditions that cause significant distress and impair daily functioning. Although standard treatments are often effective, approximately 60% of patients may not respond adequately, underscoring the need for novel therapeutic approaches.
Objective: To evaluate improvement in OCRD symptoms associated with glutamatergic medications as monotherapy or as augmentation to selective serotonin reuptake inhibitors, with a focus on double-blind, placebo-controlled randomized clinical trials (RCTs).

Importance: Hypertension underpins significant global morbidity and mortality. Early lifestyle intervention and treatment are effective in reducing adverse outcomes. Artificial intelligence-enhanced electrocardiography (AI-ECG) has been shown to identify a broad spectrum of subclinical disease and may be useful for predicting incident hypertension.

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.
Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.
Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA.
