Introduction: Neuromyelitis optica spectrum disorder (NMOSD) is a serious condition affecting people worldwide, including Latin America (LATAM). Healthcare disparities and economic limitations make effective treatment access challenging. It is crucial to consider the best practice therapeutic decision-making, including emerging long-term preventive therapies, to ensure patients in LATAM and elsewhere can effectively manage their disease all over the world.

Association of changes in the type 2 diabetes and MASLD/related SLD status with risk of developing cardiovascular disease.

Background & Aims: This study assessed the association of remission of type 2 diabetes mellitus (DM) or metabolic dysfunction-associated steatotic liver disease (MASLD)/related SLD (r-SLD; MASLD with excessive alcohol intake) as defined by the fatty liver index with the risk of cardiovascular disease (CVD).

Methods: Health examination data at baseline and after 2 years (2-Years) were extracted from a nationwide claims database in Japan. Among participants aged 18-72 years with at least 3 years of follow-up, 9345 participants with DM-associated MASLD/r-SLD and 71 932 participants with non-DM MASLD/r-SLD at baseline were included in the study.

Positive association of large alcohol intake per occasion with vision-threatening severe diabetic retinopathy or diabetic macular edema in Japanese men with type 2 diabetes.

Objective: Differing from the overall consumption of alcohol, whether consuming large quantities of alcohol per drinking occasion is associated with higher risk of developing severe diabetic retinopathy remains unknown.

Methods: We examined whether the quantity per drinking occasion (QPO), including a large QPO, and the combinations of the frequency of alcohol consumption (FAC) and QPO were associated with higher risk of developing severe diabetic retinopathy or diabetic macular edema (DME) using adjusted Cox models. Severe diabetic retinopathy or DME was designated as a vision-threatening treatment-required diabetic eye disease (TRDED).

Japan Diabetes Complications Study: Revisiting one of the first large-scale clinical studies in East Asians with diabetes.

This review highlights the significance of the Japan Diabetes Complications Study (JDCS), one of the earliest large-scale studies of people with type 2 diabetes outside Europe and the United States, in understanding type 2 diabetes mellitus among East Asian populations, particularly in Japan. Historically, large-scale clinical studies on type 2 diabetes mellitus have predominantly focused on Western populations, despite East Asians comprising the largest proportion of diabetic patients globally. The JDCS, which was initiated in 1996, enrolled 2,033 Japanese type 2 diabetes mellitus patients.

Application of High-performance Liquid Chromatography to Caprolactam Migration Testing of Food Utensils, Containers, and Packaging.

We assessed the applicability of high-performance liquid chromatography (HPLC) to the official testing method for the migration of caprolactam (CPL) from food utensils, containers, and packaging made from polyamide (PA). Hydrophilic interaction chromatography (HILIC) columns coated with unmodified silica, carbamoyl, and aminopropyl were used. Water and acetonitrile (ACN) were used as the mobile phase, and the analytical conditions were optimized.

Inhibition of amyloid β aggregation and BACE1, and protective effect on SH-SY5Y cells, by p-terphenyl compounds from mushroom Thelephora aurantiotincta.

The number of patients with Alzheimer's disease (AD) is expected to increase as the population ages. The amyloid cascade hypothesis is proposed as the pathogenic mechanism of AD. We report the isolation and structural determination of three new p-terphenyl compounds, thelephantin P (1), thelephantin Q (2), and thelephantin R (3), with four known compounds (4-7), from the fruiting bodies of Thelephora aurantiotincta Corner.

The real-world impact of biologics for NMOSD: A retrospective single-center study compared with natural course and conventional treatments in Japanese.

Background: Neuromyelitis optica spectrum disorder (NMOSD), a central nervous system inflammatory disease associated with aquaporin-4 immunoglobulin G (AQP4-IgG), is conventionally treated with oral steroids and immunosuppressants (IS) in Japan. Several biologics which show great efficacy in the clinical trials have been developed recently. However, studies on their efficacy, especially those comparing them with conventional treatments in real-world situations are lacking.

Development of a machine learning tool to predict the risk of incident chronic kidney disease using health examination data.

Background: Chronic kidney disease (CKD) is characterized by a decreased glomerular filtration rate or renal injury (especially proteinuria) for at least 3 months. The early detection and treatment of CKD, a major global public health concern, before the onset of symptoms is important. This study aimed to develop machine learning models to predict the risk of developing CKD within 1 and 5 years using health examination data.

Healthy lifestyle factors as predictors of the initiation of dialysis in people with and without diabetes.

Aims: To clarify the impact of Breslow's scores consisting of only lifestyle habits or American Heart Association's (AHA) Life's Simple 7 scores consisting of lifestyle habits and control targets on starting dialysis in people with or without diabetes mellitus (DM).

Methods: To pursue the study aims, we examined a nationwide database on 294,647 individuals with and without DM aged 19-72 y in Japan to pursue the study aims. Using multivariate Cox modeling, we evaluated and compared 5 risk factors based on the unfavorable lifestyle factors in Breslow's scores and the unfavorable lifestyle factors and clinical values in AHA Life's Simple 7 scores.

The onset and the development of cardiometabolic aging: an insight into the underlying mechanisms.

Metabolic compromise is crucial in aggravating age-associated chronic inflammation, oxidative stress, mitochondrial damage, increased LDL and triglycerides, and elevated blood pressure. Excessive adiposity, hyperglycemia, and insulin resistance due to aging are associated with elevated levels of damaging free radicals, inducing a proinflammatory state and hampering immune cell activity, leading to a malfunctioning cardiometabolic condition. The age-associated oxidative load and redox imbalance are contributing factors for cardiometabolic morbidities via vascular remodelling and endothelial damage.

Differential diagnosis of suspected multiple sclerosis: global health considerations.

The differential diagnosis of multiple sclerosis can present specific challenges in patients from Latin America, Africa, the Middle East, eastern Europe, southeast Asia, and the Western Pacific. In these areas, environmental factors, genetic background, and access to medical care can differ substantially from those in North America and western Europe, where multiple sclerosis is most common. Furthermore, multiple sclerosis diagnostic criteria have been developed primarily using data from North America and western Europe.

Clinical practice guidelines for multiple sclerosis, neuromyelitis optica spectrum disorder, and myelin oligodendrocyte glycoprotein antibody-associated disease 2023 in Japan.

Background: The previous Japanese clinical practice guidelines for multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) were published in 2017. Recently, for the first time in 6 years, the MS and NMOSD guideline development committee revised the Japanese guidelines for MS, NMOSD, and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).

Methods: The committee utilized the Grading of Recommendations Assessment, Development, and Evaluation system based on the "Minds Handbook for Clinical Practice Guideline Development 2020 Ver.

Different Complement Activation Patterns Following C5 Cleavage in MOGAD and AQP4-IgG+NMOSD.

Objectives: In myelin oligodendrocyte glycoprotein IgG-associated disease (MOGAD) and aquaporin-4 IgG+ neuromyelitis optica spectrum disorder (AQP4+NMOSD), the autoantibodies are mainly composed of IgG1, and complement-dependent cytotoxicity is a primary pathomechanism in AQP4+NMOSD. We aimed to evaluate the CSF complement activation in MOGAD.

Methods: CSF-C3a, CSF-C4a, CSF-C5a, and CSF-C5b-9 levels during the acute phase before treatment in patients with MOGAD (n = 12), AQP4+NMOSD (n = 11), multiple sclerosis (MS) (n = 5), and noninflammatory neurologic disease (n = 2) were measured.

Humanized-Aquaporin-4-Expressing Rat Created by Gene-Editing Technology and Its Use to Clarify the Pathology of Neuromyelitis Optica Spectrum Disorder.

Conventional rodent neuromyelitis optica spectrum disorder (NMOSD) models using patient-derived immunoglobulin G (IgG) are potentially affected by the differences between the human and rodent aquaporin-4 (AQP4) extracellular domains (ECDs). We hypothesized that the humanization of AQP4 ECDs would make the rodent model lesions closer to human NMOSD pathology. Humanized-AQP4-expressing (hAQP4) rats were generated using genome-editing technology, and the human AQP4-specific monoclonal antibody (mAb) or six patient-derived IgGs were introduced intraperitoneally into hAQP4 rats and wild-type Lewis (WT) rats after immunization with myelin basic protein and complete Freund's adjuvant.

Impact of health practice index and cardiovascular health metrics on incident cardiovascular disease according to glucose tolerance status.

Aims: To evaluate and compare the association of incident cardiovascular disease (CVD) with the Health Practice Index (HPI) reflecting only lifestyle habits and Ideal Cardiovascular Health Metrics (ICVHMs) consisting of lifestyle habits and factors targeted for control in the same population according to glucose status.

Methods: This retrospective cohort study included 1,28,162 participants aged 18-72 years with no history of CVD followed for ≥ 3 years between 2008 and 2016. Participants were classified according to normal glucose tolerance (86,174), prediabetes (36,096), or diabetes (5892).
