Preoperative factors associated with shunt responsiveness in patients with idiopathic normal-pressure hydrocephalus.

Objective: We aimed to evaluate a possible association between preoperative factors (disease duration and vascular risk factors) and shunt responsiveness in patients with idiopathic normal-pressure hydrocephalus (iNPH).

Methods: We conducted a retrospective observational study in a high-volume center for iNPH treatment in Japan and reviewed the clinical data of 107 consecutive patients with probable iNPH who underwent shunt surgery between January 1, 2018, and August 31, 2019, and were followed up for at least 12 months after surgery. Preoperatively, these patients underwent the timed up-and-go test (TUG) and Mini-Mental State Examination (MMSE); moreover, follow-up evaluations were performed 12 months postoperatively, at which TUG and MMSE scores were used as metrics for shunt responsiveness assessment.

Effects of anti-SSA antibodies on the response to methotrexate in rheumatoid arthritis: A retrospective multicenter observational study.

Comparison of clinical response to methotrexate between anti-SSA antibody-positive and -negative patients with methotrexate-naïve rheumatoid arthritis and investigate the reasons for the differences in the response. For this multicenter retrospective cohort study, a total of 210 consecutive patients with rheumatoid arthritis who newly initiated methotrexate were recruited. The effects of anti-SSA antibody positivity on achieving a low disease activity according to the 28-joint Disease Activity Score based on C-reactive protein after 6 months of methotrexate administration were investigated using a logistic regression analysis.

Discordance in the reduction rate between glycated albumin and glycated hemoglobin levels in type 2 diabetes patients receiving SGLT2 inhibitors.

Aims: Although the difference in HbA reduction between sodium-glucose cotransporter 2 (SGLT2) inhibitors and other oral glucose-lowering agents is relatively small, SGLT2 inhibitors exhibit beneficial cardiorenal protection. This study was based on the hypothesis that changes of HbA in patients treated with SGLT2 inhibitors may not accurately reflect an improved glycemic profile.

Methods: Two studies were conducted: 1) a retrospective cohort study of 3039 patients administered with either an SGLT2 or a dipeptidyl peptidase-4 (DPP4) inhibitor for 12 months comparing the changes in glycated albumin (GA) and HbA levels and 2) a pilot study of 10 patients whose glycemic dynamics were evaluated using flash glucose monitoring at baseline and 2 months after treatment with an SGLT2 inhibitor.

Plasma and serum prorenin concentrations in diabetes, hypertension, and renal disease.

Although the renin-angiotensin-aldosterone system plays a crucial role in fluid homeostasis and cardiovascular disease pathophysiology, measurements of plasma prorenin levels are still unavailable in clinical practice. We previously found that prorenin molecules in human blood underwent significant posttranslational modifications and were undetectable using immunological assays that utilized antibodies specifically recognizing unmodified recombinant prorenin. Using a sandwich enzyme-linked immunosorbent assay that captures posttranslationally modified prorenins with their prosegment antibodies, we measured plasma and serum prorenin concentrations in 219 patients with diabetes mellitus, hypertension and/or renal disease and compared them with those of 40 healthy controls.

Rivaroxaban, a Direct Oral Factor Xa Inhibitor, Attenuates Atherosclerosis by Alleviating Factor Xa-PAR2-Mediated Autophagy Suppression.

The authors showed a mechanism for attenuating atherosclerosis by directly administering an oral factor Xa inhibitor (ie, rivaroxaban [RIV]). The autophagy activity of macrophages was significantly suppressed by factor Xa and was alleviated by the administration of RIV. However, factor Xa failed to inhibit 7-ketocholesterol-induced autophagy and inflammasome activation in protease-activated receptor 2 (PAR2) knockout macrophages.

GIP_HUMAN[22-51] is a new proatherogenic peptide identified by native plasma peptidomics.

We recently established a new plasma peptidomic technique and comprehensively identified a large number of low-molecular weight and low-abundance native peptides using a single drop of human plasma. To discover a novel polypeptide that potently modulates the cardiovascular system, we performed a bioinformatics analysis of the large-scale identification results, sequentially synthesized the selected peptide sequences, tested their biological activities, and identified a 30-amino-acid proatherogenic peptide, GIP_HUMAN[22-51], as a potent proatherosclerotic peptide hormone. GIP_HUMAN[22-51] has a common precursor with the glucose-dependent insulinotropic polypeptide (GIP) and is located immediately N-terminal to GIP.

Unexpected Complications after Corrective Spinal Fusion Surgery for Adult Spinal Deformity with Severe Hip Contracture.

Introduction: In cases with markedly decreased hip function, patients predominantly utilize spine movement while standing up to compensate for the hip malfunction. However, spinal fusion surgeries might lead to the disruption of this compensatory mechanism, resulting in difficulties in walking and standing up as well as proximal junctional failure (PJF) due to the excessive stress on the spine caused by the pendulum-like motion needed for standing up. Hence, in patients with severe hip pathology, surgeons should be cautious about the indication for spinal fusion, which inevitably affects spinal mobility.
