Mutations in the genes , , and cause three clinically overlapping thrombocytopenias characterized by a predisposition to hematological neoplasms. The gene, which encodes a protein involved in protein-protein interactions, is downregulated by RUNX1 during megakaryopoiesis. Mutations in 5'UTR of ANKRD26, leading to ANKRD26-RT, disrupt this regulation, resulting in the persistent expression of ANKRD26, which leads to impaired platelet biogenesis and an increased risk of leukemia.

Background: There are age- and sex-related increases in the prevalence of osteoporosis. Bone densitometry based on dual energy X-ray absorptiometry (DXA) is the gold standard for the assessment of bone mineral density (BMD). Three-dimensional (3D) analysis of the proximal femur (3D-DXA) allows discrimination between cortical and trabecular compartments, and it has shown a good correlation with computed tomography.

Essential thrombocythemia is the category of myeloproliferative syndromes, generally characterized by a group of clonal stem cell diseases that present a disturbance in the growth of one or more sets of hematopoietic cells. All long clinical treatment, patients may experience gastrointestinal disorders and other metabolic processes that can lead to weight loss and malnutrition. Cytokine is involved in the control of appetite, digestive, and metabolic processes in the body, it can be assumed that increased stimulation could impair the control of these processes leading to loss of body mass.

Data on long-term treatment regimens for preventing bone mineral density (BMD) loss that occurs after denosumab (Dmab) withdrawal are scarce. Our aim was to evaluate the long-term changes (12-36 months) in BMD and bone turnover markers in a group of postmenopausal women who had been treated with Dmab and received subsequent treatment with bisphosphonates. Secondary objectives were to evaluate factors associated with BMD loss, to compare the BMD change in patients who received oral vs intravenous bisphosphonates, and to assess the frequency of fragility fractures after Dmab discontinuation.

Article Synopsis
  • ACTN1-related thrombocytopenia is caused by genetic mutations in the ACTN1 gene, leading to large platelets and mild bleeding issues.
  • Two sisters with a specific homozygous variant showed moderate thrombocytopenia and significantly larger platelets than their heterozygous relatives, suggesting a stronger genetic impact on platelet size.
  • The study also proposes a link between certain ACTN1 variants and heart valve defects, indicating that these genetic changes may affect both blood cell characteristics and cardiac health.

Few cases of spontaneous bowel evisceration (SBE) through umbilical hernias (UHs) in adult patients have been reported in the literature. Interestingly, the spontaneous rupture of the hernia sac is a rare complication usually seen in adult cirrhotic patients with persistent ascites or in patients with congenital wall defects. A man in his early 50s was admitted to our emergency department with SBE through a long-standing acquired UH.

To date, caval sparing (CS) and total caval replacement (TCR) for recipient hepatectomy in liver transplantation (LT) have been compared only in terms of surgical morbidity. Nonetheless, the CS technique is inherently associated with an increased manipulation of the native liver and later exclusion of the venous outflow, which may increase the risk of intraoperative shedding of tumor cells when LT is performed for HCC. A multicenter, retrospective study was performed to assess the impact of recipient hepatectomy (CS vs.

Background: Therapeutic drug monitoring (TDM) using cyclin-dependent kinase inhibitors (CDK4/6is) is a novel approach for optimizing treatment outcomes. Currently, palbociclib, ribociclib, and abemaciclib are the available CDK4/6is and are primarily coadministered with letrozole. This study aimed to develop and validate an LC-MS/MS method for the simultaneous analysis of CDK4/6is, 2 active metabolites of abemaciclib (M2 and M20), and letrozole in human plasma for use in TDM studies.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract with a 1-3% prevalence in the general population. The surgical management of symptomatic MD is well described in the literature, but there is still no consensus on the indication for prophylactic resection of incidental asymptomatic MD. To address this issue, we extensively reviewed the current literature and report our experience with laparoscopic management of an unusual case of MD causing ileal volvulus and acute peritonitis two weeks after a laparoscopic appendectomy for acute gangrenous appendicitis performed in another hospital.
