Introduction: Cervical cancer is the fourth most common cancer among women worldwide. Most cervical cancers are caused by persistent infection with human papillomavirus (HPV) acquired through sexual contact. Decision-making is the process of choosing among several options, and a better decision is one that the people engaged in the decision-making process express satisfaction with.

Obinutuzumab frequently triggers an infusion reaction(IR). In the GALLIUM study, despite the use of corticosteroids, antipyretic analgesics, and antihistamines to prevent IR, IR occurred at a high frequency of 68.2% for all Grades and 12.

Although the association between gestational diabetes mellitus (GDM) and maternal postpartum depression has been reported, the association between these two factors during pregnancy has not been sufficiently examined. We compared pregnant women with and without GDM to clarify the association and examined factors related to depression in pregnant women with GDM. Questionnaires were administered longitudinally to pregnant Japanese women in the third trimester and at 2 and 4 weeks postpartum.

Inverted internal limiting membrane (ILM) flap technique was developed to achieve macular hole (MH) closure in large MH and refractory cases. In this study, we evaluate the effect of the technique for small-medium size MH. We recruited patients who underwent vitrectomy for small-medium size (< 400 μm) MH with either inverted ILM flap technique (flap group) or with conventional ILM peeling (peeling group).

Purpose: To investigate whether the resistivity of all retinal vessels, termed total capillary resistance (TCR), after anti-vascular endothelial growth factor (VEGF) treatment was correlated with the outcomes of patients with macular edema secondary to central retinal vein occlusion (CRVO).

Methods: In total, 67 patients with nonischemic CRVO were enrolled in this retrospective observational case series. In each patient, we examined visual acuity; central retinal thickness (CRT); mean blur rate (MBR), which represents retinal blood flow velocity; and TCR.

Determining values of plasma renin activity (PRA) or plasma active renin concentration (ARC), plasma aldosterone concentration (PAC), and aldosterone-to-renin ratio (ARR) is essential to diagnose primary aldosteronism (PA), but it takes several days with conventional radioimmunoassays (RIAs). Chemiluminescent enzyme immunoassays for PAC and ARC using the Accuraseed® immunoanalyzer facilitated the determination, but relations between Accuraseed® immunoanalyzer-based and RIA-based values in samples of PA confirmatory tests and adrenal venous sampling remained to be elucidated. We addressed this issue in the present study.

Purpose: Evaluation of blood flow is useful for understanding the severity of central retinal vein occlusion (CRVO). Actual blood flow may be determined by the resistivity of the retinal vein in CRVO. We have previously evaluated mean blur rate (MBR) to reflect total retinal blood flow velocity in CRVO cases using laser speckle flowgraphy (LSFG).

In Japan, primary aldosteronism (PA) is diagnosed if any one of the captopril challenge test (CCT), saline infusion test (SIT), furosemide-upright test (FUP), and oral salt-loading test (OST) is positive. The present study aimed to investigate if parameters of CCT, the safest confirmatory test, could predict decisions of other tests and propose the next test to diagnose PA in CCT-negative patients. In a cross-sectional design, 142 patients, who were referred to our hospital for the scrutiny of PA and underwent at least two confirmatory tests, were enrolled.

The USA300 clone, which produces Panton-Valentine leukocidin (PVL), is a major highly pathogenic community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) clone that is spreading throughout the world. Although the prevalence of the USA300 clone in Japan was very limited a decade ago, its incidence has been increasing in both community and hospital settings in recent years. There is great concern that the USA300 clone will cause more complicated diseases and become a serious threat to immunocompromised patients in hospital settings.

Background: To report the case of a patient with pseudoxanthoma elasticum (PXE) and proliferative diabetic retinopathy (PDR), and discuss the relationship between PXE and diabetic retinopathy (DR).

Case Presentation: A 47-year-old man with PXE presented with angioid streaks and DR in both eyes, and bilateral panretinal photocoagulation was performed for treatment. Vitrectomy had previously been performed in his right eye for vitreous hemorrhage due to PDR.

Staphylococcus epidermidis, a major skin flora on hands, acts as a reservoir of various antimicrobial resistance determinants including staphylococcal cassette chromosome mec (SCCmec) and contributes to multidrug resistance for S. aureus. The aim of this study was understanding the characteristics of commensal S.

Article Synopsis
  • - The study investigates the bactericidal effects of tetramic acids from Pseudomonas autoinducers on Clostridium difficile, a bacterium responsible for antibiotic-related colitis.
  • - Testing involved incubating clinical strains of C. difficile with synthesized autoinducers and their derivatives, revealing significant reductions in bacterial viability within 30 minutes.
  • - The findings indicate that specific structural features of tetramic acids may enhance their antibacterial properties, suggesting their potential use as new treatment options against C. difficile infections.

Article Synopsis
  • Mannan-binding protein (MBP) is a serum lectin that activates the immune complement system by binding to specific sugars on microbes and has demonstrated the ability to inhibit the growth of human colorectal cancer cells in experimental mice.
  • This study identified that fucose is essential for MBP's binding to the surface of SW1116 cancer cells, suggesting a significant interaction at the cellular level.
  • The researchers characterized the MBP ligands, identifying them as complex multiantennary N-glycans with a fucosylated polylactosamine structure, revealing new insights into how MBP recognizes these cancer cells through specific sugar patterns.
