Effectiveness of inactivated influenza vaccine in children during the 2023/24 season: The first season after relaxation of intensive COVID-19 measures.

Background: The annual administration of the influenza vaccine is the most effective method for preventing influenza. We have evaluated the effectiveness of the inactivated influenza vaccine in children aged 6 months to 15 years across the seasons from 2013/2014 to 2022/2023. This study aims to investigate the effectiveness of the inactivated influenza vaccine in the 2023/2024 season, the first year following the easing of strict COVID-19 measures, and possibly the last season when only the inactivated vaccine is available on the market.

Usefulness of color Doppler and strain elastography adjunctive to B-mode ultrasonography in the diagnosis of non-mass abnormalities of the breast: results of the BC-07 multicenter study of 385 cases.

Purpose: The concept of non-mass abnormalities of the breast has been employed in Japan for approximately 20 years. Although B-mode findings are classified as non-mass abnormalities, the usefulness of adding color Doppler ultrasonography (US) and strain elastography to B-mode US is unclear. Therefore, we conducted a multicenter study (JABTS BC-07) to establish the diagnostic criteria for breast US, including color Doppler and elastography, for non-mass abnormalities of the breast and verify their diagnostic usefulness.

The key to success in blocking lateral cutaneous branches with re-modified thoracoabdominal nerves block through perichondrial approach: a newly discovered space between the endothoracic fascia, diaphragm, and costodiaphragmatic recess.

Purpose: This study aimed to determine whether the administration of a modified thoracoabdominal nerves block through perichondrial approach (M-TAPA) could result in the blockade of the lateral cutaneous branches. This study focused on a newly discovered anatomical space/plane adjacent to the M-TAPA plane, which we termed "space between the endothoracic fascia, diaphragm, and costodiaphragmatic recess: SEDIC."

Methods: Thirteen sides of nine formalin-embalmed cadavers were macroscopically dissected to investigate the anatomical spaces related to the effects of M-TAPA.

Mineralocorticoid receptor overactivation in diabetes mellitus: role of O-GlcNAc modification.

Hypertension is a significant risk factor for microangiopathy and cardiovascular complications in diabetic patients. The efficacy of mineralocorticoid receptor (MR) antagonists in impeding the advancement of diabetic nephropathy, along with the reduction in active renin concentration observed in diabetic retinopathy, strongly implies the involvement of MR overactivation in diabetic complications. This review provides a comprehensive review of various mechanisms proposed for MR overactivation in diabetes mellitus.

Dynamic Cervical Spinal Canal Stenosis: Identifying Imaging Risk Factors in Extended Positions.

Study Design: A retrospective study at a single academic institution.

Purpose: This study aimed to identify imaging risk factors for stenosis in extended neck positions undetectable in preoperative neutral magnetic resonance imaging (MRI) and improving decompression strategies for cervical spine disorders.

Overview Of Literature: Cervical disorders are influenced by various dynamic factors, with spinal stenosis appearing during neck extension.

Location and size of the reverse Hill-Sachs lesion in patients with traumatic posterior shoulder instability.

Background: In patients with traumatic posterior shoulder instability, little is known about the precise location and size of the reverse Hill-Sachs lesion.

Methods: Forty-nine shoulders of 47 patients with traumatic posterior instability were included in this study based on the following inclusion criteria: (1) a primary or recurrent traumatic posterior shoulder dislocation and (2) the initial event being caused by trauma. Patients were excluded if they had (1) no history of trauma, (2) prior shoulder surgery, (3) no computed tomographic (CT) examination, or (4) were seizure cases.

Clinical performance and shape analysis of trifocal intraocular lenses via scanning electron microscopy.

Background: To evaluate visual performance after implantation of the TFNT (Acrysof Panoptix, Alcon, Fort Worth, Texas, USA) and CNWT (Clareon Panoptix, Alcon, Fort Worth, Texas, USA) intraocular lens (IOL), and compare the lens shape observed by scanning electron microscope (SEM).

Methods: Eighteen patients (18 eyes) received implantation of the CNWT and Twenty patients (20 eyes) received implantation of the TFNT. Exclusion criteria were previous ocular surgeries, ocular pathologies, or corneal abnormalities.

A case study of pyloric stenosis caused by metastatic lobular carcinoma of breast.

Metastasis to the gastrointestinal tract is rare. A 59-year-old woman who had a history of an invasive lobular carcinoma of breast with clinical complete response visited our hospital and complained of an upper abdominal pain and distension. We performed an upper gastrointestinal endoscopy which showed only a gastric ulcer without any malignant findings.

IgG4-related pancreatobiliary diseases could be associated with onset of pancreatobiliary cancer: A multicenter cohort study.

Background: The risk and prognosis of pancreatobiliary cancer and in patients with autoimmune pancreatitis (AIP) and IgG4-related sclerosing cholangitis (IgG4-SC) remain unclear. Therefore, we retrospectively investigated the risk of pancreatobiliary cancer and prognosis in patients with AIP and IgG4-SC.

Methods: Patients with AIP and IgG4-SC at seven centers between 1998 and 2022 were investigated.

Calcium channel blockers may reduce the development of long COVID in females.

With the rising numbers of patients infected with severe acute respiratory syndrome coronavirus 2, long coronavirus disease 2019 (COVID-19)-a sequelae of COVID-19-has become a major problem. Different sexes and age groups develop different long COVID symptoms, and the risk factors for long COVID remain unclear. Therefore, we performed subgroup analyses of patients with COVID-19, classifying them into different groups.

The Japanese Breast Cancer Society Clinical Practice Guidelines for surgical treatment of breast cancer, 2022 edition.

The 2022 revision of the Japanese Breast Cancer Society (JBCS) Clinical Practice Guidelines for surgical treatment of breast cancer was updated following a systematic review of the literature using the Medical Information Network Distribution Service (MINDS) procedure, which focuses on the balance of benefits and harms for various clinical questions (CQs). Experts in surgery designated by the JBCS addressed five areas: breast surgery, axillary surgery, breast reconstruction, surgical treatment for recurrent and metastatic breast cancer, and other related topics. The revision of the guidelines encompassed 4 CQs, 7 background questions (BQs), and 14 future research questions (FRQs).

A Case in Which Breast Cancer Developed at the Same Time As Dermatomyositis, and the Onset of New Cancer Was Able to Be Predicted by the Exacerbating Skin Symptoms and Parallel Increase in the Anti-TIF1-γ Antibody Levels.

Dermatomyositis (DM) is an idiopathic inflammatory myopathy. The incidence of malignancy in DM patients is quite high. Anti-transcription intermediary factor 1-γ (anti-TIF1-γ) antibody is more prevalent in DM patients with malignancy than in those without malignancy.
