Background: Allogeneic hematopoietic cell transplantation (allo-HCT) is a potential cure for many hematological malignancies. Historically, older adults were not considered eligible for allo-HCT due to increased toxicity and mortality concerns. This systematic review and meta-analysis aim to explore the outcomes of allo-HCT in patients aged 70 years or older.

Background: Hematopoietic stem cell transplantation (HCT) is a pivotal treatment modality for primary plasma cell leukemia (pPCL). We aimed to examine the outcomes of allogeneic (allo) and autologous (auto) HCT in adult pPCL patients.

Methods: Following PRISMA guidelines, a comprehensive literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.

Burns are injuries to the skin or the underlying tissue system caused by heat, radiation, electricity, friction or chemicals. Burns can cause pain and discomfort during dressing changes; a person's pain response varies depending on individual perception. The pain response can indicate tissue damage in the body, as pain causes a person to experience discomfort.

Article Synopsis
  • * Treatments like conventional chemotherapy and new therapies, such as venetoclax, have limited success for patients with TP53 mutations, leading to low response rates and poor survival outcomes.
  • * Allogeneic stem cell transplantation offers a potential cure but is influenced by the patient's overall health and disease stage, while newer immune-based therapies have not yet proven effective in larger trials.

Background: Chimeric antigen receptor T cell (CAR-T) therapy is an emerging form of immunotherapy that has recently gained recognition for treating hematological malignancies. This successful utilization of CAR-T therapy has attracted interest in its application in refractory rheumatological diseases. Here, we will review the use of CAR-T therapy in rheumatological diseases.

Article Synopsis
  • Idiopathic Pneumonia Syndrome (IPS) is a serious complication that can occur after allogeneic hematopoietic stem cell transplantation (allo-HSCT), potentially leading to high morbidity and mortality, often due to inflammatory damage.
  • This study examines the use of Ruxolitinib, a JAK inhibitor, combined with corticosteroids (CS) in treating IPS compared to standard corticosteroid treatment, through a case series of three patients and a systematic review of previous literature involving 346 cases.
  • Results indicated that the three patients treated with Ruxolitinib and CS showed significant improvement without mortality linked to IPS, and the systematic review supported these findings across a diverse patient demographic.

Background No reliable risk stratification method is available to guide the extent of infectious work-up among hospitalized patients with cirrhosis. Therefore, we aimed to create a risk stratification method for obtaining blood cultures from hospitalized patients with cirrhosis. Methods This was a retrospective cohort study using the Healthcare Cost and Utilization Project - National Readmission Database 2019.

Introduction: Bleeding, especially non-variceal upper gastrointestinal bleeding (NVUGIB), remains the most common cause of readmission in left ventricular assist device (LVAD) patients. Any readmission after NVUGIB carries a worse prognosis.

Aim: To compare readmission outcomes in NVUGIB patients with and without LVAD.

  • Nivestym, a biosimilar to Neupogen, is being evaluated for its effectiveness in mobilizing peripheral blood stem cells (PBSC) in healthy donors for allogeneic hematopoietic stem cell transplantation (allo-HSCT).
  • A retrospective study analyzed data from 541 donors who received either Nivestym or Neupogen, focusing on factors like donor age, weight, and various counts of cells before and after treatment.
  • Results showed that while Nivestym was generally as effective as Neupogen for PBSC mobilization, younger donors (under 35) had a slightly lower CD34 cell count after using Nivestym compared to those using Neupogen.

This case report details a complex case of parotid gland sialolithiasis with stones adherent to the facial nerve, a scenario that presents a significant surgical challenge. Traditional sialendoscopy failed to address the condition in a 23-year-old female patient, leading to the adoption of a combined endoscopic transcutaneous approach. This method successfully resolved the condition without intraoperative complications, maintaining intact facial nerve function postoperatively.

Vacuoles, E1 syndrome, X-linked, autoinflammatory, somatic (VEXAS) syndrome is a chronic inflammatory disorder that affects various organ systems. It is associated with hematologic malignancies and is generally refractory to therapies. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be considered for selected patients.

This systematic review aimed to evaluate the proportion of primary and secondary endpoints in hematopoietic stem cell transplant (HSCT) phase III randomized clinical trials (RCTs) and analyze their trends in time and study sponsorship status. The Chi-square test and logistic regression analyses were performed using SPSS version 28. A total of 147 HSCT phase III RCTs from 2006 to 2021 reported 197 primary and 600 secondary endpoints.

Background: We aimed to investigate factors associated with cytomegalovirus (CMV) viremia and CMV disease and its impact on post-transplant outcomes including overall survival (OS) following allogeneic hematopoietic stem cell transplantation (Allo-SCT).

Methods: We conducted a single-center retrospective study including 452 Allo-SCT recipients (matched unrelated donor, MUD 61%; haploidentical, haplo 39%) from 2016 to 2021. Data were analyzed using SPSS v28.

Article Synopsis
  • - The study examines geographical and racial disparities in access to CAR-T and bispecific antibodies clinical trials for DLBCL, focusing on data from ClinicalTrials.gov and the 2020 US Census.
  • - Out of 75 trials identified, 85% were US-based, primarily funded by pharmaceutical companies, with a concentration of trials in southern and midwestern states, and many states having no trials at all.
  • - Significant racial disparities were found, as only 33% of African Americans lived in counties with trial access, with a majority of trial locations situated in predominantly White areas, emphasizing the need for strategies to improve equity in clinical trial access.

We investigated the outcomes after adult haploidentical (haplo) and matched unrelated donor (MUD) hematopoietic cell transplantation (HCT) in a single-center study ( = 452) including 276 MUD and 176 haplo transplants. Myeloablative (37%) and reduced-intensity conditioning (63%) were performed. Graft sources included peripheral blood (50%) and bone marrow (50%).

Introduction: Upper gastrointestinal bleeding is common in liver cirrhosis patients. Studies have described the prognostic impact of liver disease in non-variceal upper gastrointestinal bleeding (NVUGIB), but a direct subgroup comparison is lacking using a large database.

Aim: To study the impact of NVUGIB on hospital-based outcomes in patients with cirrhosis.

This study aimed to develop surface modified PLGA nanocarriers protecting a protein-based antigen in the stomach to enable potential release of the antigen at target intestinal sites. PLGA nanoparticles (NPs) were prepared by double emulsion and solvent evaporation techniques while surface functionalization was performed using polyethylene glycol (PEG), sodium alginate (ALG) and Eudragit L100 (EUD) with ovalbumin (OVA) as a model protein antigen. Nanoparticles were characterized by dynamic light scattering (DLS), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), and stability in simulated gastric fluid (SGF)/simulated intestinal fluid (SIF).

Amid the coronavirus disease 2019 (COVID-19) pandemic, there is an unprecedented increase in public avoidance of hospitals predominantly driven by fear of contracting the virus. Recent publications highlight a re-emergence of rare post-myocardial infarction complications. While mechanical complications are infrequent in the era of primary percutaneous coronary intervention, they are associated with high mortality rates.

The study compared performance of nanoparticles prepared from synthetic organic, natural organic and inorganic materials as vaccine delivery platforms. Various formulation (concentration, polymer/silica:surfactant ratio, solvent) and process parameters (homogenization speed and time, ultrasonication) affecting functional performance characteristics of poly(lactic--glycolic acid) (PLGA), chitosan and silica-based nanoparticles containing bovine serum albumin were investigated.
