Atmospheric CO levels have been rising due to an increase in anthropic activities and its implications over marine ecosystems are unprecedented. The present study focused on the effects of ocean acidification (OA) on key hematological parameters of the juvenile small-spotted catsharks (Scyliorhinus canicula). Eggs were reared throughout the entire embryogenesis (~4 months) plus 5 additional months, in two experimental treatments (control: pCO ~ 400 μatm; and high CO : pCO ~ 900 μatm, Δ -0.3 pH units). After blood collection, the following hematological parameters were evaluated: (a) normal blood cells count (erythrocytes, leukocytes, and thrombocytes), (b) presence of erythrocytes with nuclear abnormalities, and (c) erythrocyte nucleus to cytoplasmic ratio. Concomitantly, to determine the cardiac and hematopoietic conditions, the spleen and heart to body ratios were also assessed. The present findings indicate that the measured variables may not be affected by elevated pCO in this temperate species, as no significant differences were observed between treatments across all the endpoints tested. Nonetheless, it is worth mentioning a decreasing trend observed in a number of thrombocytes associated with OA, which should foster further investigation, regarding other aspects of their coagulation response. Along with OA, other stressors are expected to impact marine life, such as warming and hypoxia. Thus, future research should aim to investigate the cumulative effect of these stressors on hematological parameters in sharks.

Background: Repeated polyserositis, another name for familial Mediterranean fever (FMF), is an autoimmune disorder with an autosomal recessive nature primarily characterized by short-lived repeated periods of peritonitis, pleuritis, and arthritis, generally accompanied by fever.
Methods: Our participants were divided into two groups. Group I (patients): 100 individuals who were diagnosed as patients with FMF and were monitored.

In the pursuit of personalized medicine, there is a growing demand for computational models with parameters that are easily obtainable to accelerate the development of potential solutions. Blood tests, owing to their affordability, accessibility, and routine use in healthcare, offer valuable biomarkers for assessing hemostatic balance in thrombotic and bleeding disorders. Incorporating these biomarkers into computational models of blood coagulation is crucial for creating patient-specific models, which allow for the analysis of the influence of these biomarkers on clot formation.
View Article and Find Full Text PDFAims: To compare the effects of ipragliflozin, a sodium-dependent glucose transporter-2 inhibitor, and those of metformin on the visceral fat area (VFA), a prospective, multi-centre, open-label, blinded-endpoint, randomized, controlled study was undertaken. The generated data were used to examine the effects of ipragliflozin and metformin on indices of hepatic steatosis and liver fibrosis.
Materials And Methods: In total, 103 Japanese patients with type-2 diabetes (T2D), body mass index (BMI) of ≥22 kg/m and glycated haemoglobin level of 7%-10% were randomly administered ipragliflozin 50 mg or metformin 1000 mg for 24 weeks.
Improving prognostic evaluations in patients with stage IIIb light chain cardiac amyloidosis: role of haemodynamic parameters.

Background: There is no unified prognostic scoring system for light chain cardiac amyloidosis (AL-CA), particularly stage IIIb AL-CA. This study aimed to use invasive haemodynamic information to investigate markers that can more accurately evaluate the prognosis of patients with stage IIIb AL-CA.
Methods: In this retrospective cohort study, we conducted invasive haemodynamic measurements concurrently with myocardial biopsies to diagnose AL-CA.

Background: Prior research indicates that engaging in physical activity during chemotherapy can positively influence both physical and psychological parameters in individuals with hematological neoplasms. However, the most effective type, level, intensity, and frequency of exercise remains unclear.
Patients And Methods: We enrolled 53 patients to a clinical trial assessing a partly supervised hybrid training program including both strength and endurance components, commencing at onset of induction therapy (T0) for hematological malignancies, including AML (n = 29), ALL (n = 5), and NHL (n = 19).
