Article Synopsis
  • - A study was conducted to assess whether changing antibiotics or adding glycopeptide antibiotics helps patients with persistent febrile neutropenia (FN) after autologous hematopoietic cell transplantation (auto-HCT) recover faster.
  • - The analysis involved 208 patients, and it found no significant improvement in recovery time for those who switched antibiotics; in fact, adding glycopeptides was linked to a longer recovery time.
  • - The conclusion suggested that routine changes in antibiotics might not be beneficial for treating persistent FN after auto-HCT, indicating a need to reconsider common antibiotic management practices in such cases.

Risk-stratified breast screening has been proposed as a strategy to overcome the limitations of age-based screening. A prospective cohort study was undertaken within the PERSPECTIVE I&I project, which will generate the first Canadian evidence on multifactorial breast cancer risk assessment in the population setting to inform the implementation of risk-stratified screening. Recruited females aged 40-69 unaffected by breast cancer, with a previous mammogram, underwent multifactorial breast cancer risk assessment.

Gut microbiota-based prediction for the transition from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) in a remote island cohort study.

Diabetes Res Clin Pract

July 2024

Division of Endocrinology, Diabetes and Metabolism, Hematology, Rheumatology, (Second Department of Internal Medicine), Graduate School of Medicine, University of the Ryukyus, Okinawa, Japan. Electronic address:

Aim: The present cohort study explored whether specific gut microbiota (GM) profile would predict the development of impaired glucose tolerance (IGT) in individuals with normal glucose tolerance (NGT).

Methods: A total of 114 study subjects with NGT in Kumejima island, Japan participated in the present study and underwent 75 g oral glucose tolerance tests at baseline and one year later. We compared the profile of GM at baseline between individuals who consistently maintained NGT (NRN, n = 108) and those who transitioned from NGT to IGT (NTI, n = 6).

Purpose: Vitreous humor (VH) is used for postmortem biochemical studies because it is well protected in an uncontaminated state even after death. The goal of this research was to investigate electrolyte concentrations in the VH from human eyes with and without a history of vitrectomy surgery.

Methods: We analyzed the sodium (Na), potassium (K), chloride (Cl) and magnesium (Mg) concentrations from 34 VH samples from 34 patients.

Diabetic nephropathy (DN) is a major cause of chronic kidney disease. Microalbuminuria is currently the most common non-invasive biomarker for the early diagnosis of DN. However, renal structural damage may have advanced when albuminuria is detected.

Notable treatment advances have been made in recent years for patients with myelodysplastic syndromes/neoplasms (MDS), and several new drugs are under development. For example, the emerging availability of oral MDS therapies holds the promise of improving patients' health-related quality of life (HRQoL). Within this rapidly evolving landscape, the inclusion of HRQoL and other patient-reported outcomes (PROs) is critical to inform the benefit/risk assessment of new therapies or to assess whether patients live longer and better, for what will likely remain a largely incurable disease.

Division of Clinical Laboratory Medicine, Department of Multidisciplinary Internal Medicine, Tottori University, Yonago, Japan.

Article Synopsis
  • The study analyzed the effects of the anti-CD38 antibody daratumumab (Dara) before autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients, involving 2,626 patients from 2017 to 2020.
  • Results showed that patients not receiving Dara (Dara- group) had better 1-year progression-free survival (87.4%) and overall survival rates (96.7%) compared to those receiving Dara (Dara+ group, with 77.3% and 90.0%, respectively).
  • Factors like younger age, low disease stage, and effective treatment response before ASCT were linked to better survival outcomes, while patients achieving good responses with Dara

Objective: The purpose of this study was to identify the M protein trans-acting positive regulator (Mga) orthologue and its adjacent M-like protein (SCM) alleles in Streptococcus canis.

Results: Using the 39 SCM allele isolates and polymerase chain reaction-based amplification and sequencing, we obtained the deduced Mga amino acid (AA) sequences. The 22 Mga sequences in whole-genome sequences were obtained by searching the National Collection of Type Cultures 12,191(T) Mga sequence into the database.

Background: The spread of transmissible plasmids with carbapenemase genes has contributed to a global increase in carbapenemase-producing Enterobacterales over the past two decades, with and among the most prevalent carbapenemase genes.

Objectives: To characterize an isolate co-carrying and (JBEHAAB-19-0176) that was isolated in the Japan Antimicrobial Resistant Bacterial Surveillance in 2019-20, and to evaluate the functional advantage of carrying both genes as opposed to only one.

Methods: The whole-genome sequence of the isolate was determined using long- and short-read sequencing.

Objectives: An increasing number of drug-resistant bacteria have been identified recently. In particular, drug-resistant bacteria have been linked to unfavorable prognoses in patients with bacteremia, highlighting the need for rapid testing. Our previous studies have focused on the utility of a drug susceptibility testing microfluidic (DSTM) method using microfluidic channels.

Article Synopsis
  • Mutations in the UBA1 gene, which are linked to VEXAS syndrome, have been found in patients with myelodysplastic syndromes (MDS), with a study identifying 7% of a cohort having specific UBA1 mutations.
  • An additional sequencing analysis of a larger group revealed 1% with other potentially harmful variants, and all 40 identified patients with likely/pathogenic mutations were male with various MDS subtypes.
  • Most patients with UBA1 mutations exhibited symptoms consistent with VEXAS syndrome, suggesting that routine screening for UBA1 mutations should be considered in MDS management.

  • The study measured inflammatory cytokines in the bronchial lining fluid and plasma of 27 patients with acute respiratory failure due to severe COVID-19.
  • Key findings showed significantly higher concentrations of several cytokines (like IL-6 and IL-8) in the bronchial fluid compared to healthy volunteers, suggesting heightened lung inflammation.
  • The research indicates that analyzing cytokines in bronchial fluid offers valuable insights into inflammation in patients with severe pneumonia, highlighting a different inflammatory response in the lungs versus the bloodstream.

Article Synopsis
  • Routine hemostasis tests like prothrombin time and fibrinogen are often abnormal in chronic liver disease patients but don't reliably predict bleeding risk during procedures.
  • * This population has altered blood clotting factors, leading to a state of rebalanced hemostasis that isn't captured by standard tests.
  • * Viscoelastic hemostatic assays (VHA) could help assess overall clotting ability and guide blood transfusions in liver transplant settings, but more research is needed to determine their effectiveness for patients with cirrhosis during procedures.

Background: Cementoblastoma is a rare odontogenic tumor characterized by the formation of osteocementum-like tissue on a tooth root directly by neoplastic cementoblasts. Although it is categorized as benign, it has a high potential for growth with a certain degree of recurrence risk. However, there are only a few studies describing the features of recurrent cementoblastoma.
