Abdominal Wall Dehiscence After Laparotomy Closure in Abdominal Surgery: a Retrospective Observational Study on the Influence of the Suture Used
In this retrospective longitudinal observational study we compare the incidence of fascial dehiscence and incisional hernia in patients operated via abdominal wall incision, comparing the barbed suture Stratafix Symmetric to other types of suture during closure of the abdominal wall. In addition, we plan to analize the impact of other …

Retrospective evaluation of a cohort of patients diagnosed with pre- and postnatal urinary dilatation: outcome and long-term follow-up
" Fume Events in Air Flights: Consequences on Cabin Air Quality and on Aircrews Health of a French Fleet of Aircraft"
The subject of the study focuses on commercial aircraft's cabins air quality, under conditions of both fume events and non-fume events. It also delves into the immediate and delayed repercussions of these events on the health of aviation crew members. The expological facet of this study is directed at the …
A Real-world Study of Tenecteplase Versus Alteplase for Thrombolysis in Patients Within 4.5 H of Onset of Ischemic Stroke
Stroke is the second leading cause of death worldwide, killing nearly 7 million people every year. Acute ischemic stroke is caused by focal cerebral hypoperfusion, usually due to embolism or atherosclerotic disease . Ischemic strokes account for 60-70% of all strokes worldwide and are severely debilitating, drawing considerable attention due …
Sj-subway, a Predictor for the Recurrence of High-risk Hormone Receptor-positive Breast That is Sensitive to Extended Endocrine Therapy
Hormone receptor-positive breast cancer accounts for about 70% of all breast cancers. Extended endocrine therapy with aromatase inhibitor is the current main treatment for hormone receptor-positive breast cancer. However, previous studies have shown a long-lasting risk of the recurrence of hormone receptor-positive breast cancer at early stage, and disease recurrence …
A Study to Assess the Long-Term Safety of Ustekinumab Versus Other Biologics in Patients With Crohn's Disease and Ulcerative Colitis
The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).
A Natural History Study Seeks to Understand the Clinical, Genomic, Pharmacological, Laboratory, and Dietary Determinates of Pyrimidine and Purine Metabolism Disorders
Background Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that …
