Prognostic implications of the global leadership initiative on malnutrition criteria as a routine assessment modality for malnutrition in hospitalized patients at a university hospital.

Background & Aims: Few studies have examined the association between mortality and malnutrition diagnosed using the Global Leadership Initiative on Malnutrition (GLIM) criteria for routine nutritional assessment; thus, this association is not well known. We aimed to clarify the association between GLIM-defined malnutrition and mortality in a large population of hospitalized patients.

Methods: In this retrospective cohort study, we enrolled adult patients admitted to Aichi Medical University Hospital between April 2019 and March 2021, who underwent nutritional assessment using the GLIM criteria.

Evaluation of Adjunctive Ultrasonography for Breast Cancer Detection Among Women Aged 40-49 Years With Varying Breast Density Undergoing Screening Mammography: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Mammography has limited accuracy in breast cancer screening. Ultrasonography, when used in conjunction with mammography screening, is helpful to detect early-stage and invasive cancers for asymptomatic women with dense and nondense breasts.

Objective: To evaluate the performance of adjunctive ultrasonography with mammography for breast cancer screening, according to differences in breast density.

Horizontally transmitted parasitoid killing factor shapes insect defense to parasitoids.

Interkingdom competition occurs between hymenopteran parasitoids and insect viruses sharing the same insect hosts. It has been assumed that parasitoid larvae die with the death of the infected host or as result of competition for host resources. Here we describe a gene family, (), that encodes proteins toxic to parasitoids of the Microgastrinae group and determines parasitism success.

Neuromyelitis Optica Spectrum Disorder Complicated by Posterior Reversible Encephalopathy Syndrome as an Initial Manifestation.

A 25-year-old woman was admitted to our hospital due to tonic convulsion with severe headache after having experienced symptoms of nausea and vomiting for a month. Brain magnetic resonance imaging showed extensive symmetrical lesions in the cortical and subcortical areas of parieto-occipital lobes and basal ganglia, consistent with typical characteristics of posterior reversible encephalopathy syndrome (PRES). Furthermore, some residual lesions in the left side of dorsal medulla oblongata and central area of the cervical spinal cord along with the presence of serum anti-aquaporin-4 antibody yielded the diagnosis of neuromyelitis optica spectrum disorder (NMOSD).

How Should Health Professionals and Policy Makers Respond to Substandard Care of Detained Immigrants?

More people, including children and pregnant women, are being detained for longer periods in a patchwork of over 200 detention centers around the country, most of which are private facilities or county jails. Human Rights Watch has documented systemic medical care failures at these facilities, including incompetent treatment, which is linked to patient deaths. Clinicians working in these facilities face formidable obstacles to providing adequate care, two of which are the Department of Homeland Security's lack of reasonable alternatives to detention and insufficient staffing.

[A case of an anti-SRP myopathy with enlargement of the thymus].

A 54-year-old female was admitted to our hospital because of the Raynaud phenomenon and muscle weakness of the upper limbs. The neurological findings showed somatic and proximal limb weakness. Laboratory studies showed a high serum creatine kinase level.

[Autoantibodies detected in acetylcholine receptor antibody-negative myasthenia gravis].

Myasthenia gravis (MG) is caused by the failure of neuromuscular transmission mediated by pathogenic autoantibodies (Abs) against the acetylcholine receptor (AChR), muscle-specific receptor tyrosine kinase (MuSK), and unknown autoantibodies. The seropositivity rates for routine AChR binding Ab and MuSK Ab in MG are 85% and a few % for MG patients in Japan, respectively. The autoimmune target in the remaining patients is unknown.

Diurnal variation of human sweet taste recognition thresholds is correlated with plasma leptin levels.

Objective: It has recently been proposed that the peripheral taste organ is one of the targets for leptin. In lean mice, leptin selectively suppresses gustatory neural and behavioral responses to sweet compounds without affecting responses to other taste stimuli, whereas obese diabetic db/db mice with defects in leptin receptor lack this leptin suppression on sweet taste. Here, we further examined potential links between leptin and sweet taste in humans.

Leptin modulates behavioral responses to sweet substances by influencing peripheral taste structures.

Leptin is a hormone that regulates body weight homeostasis mainly via the hypothalamic functional leptin receptor Ob-Rb. Recently, we proposed that the taste organ is a new peripheral target for leptin. Leptin selectively inhibits mouse taste cell responses to sweet substances and thereby may act as a sweet taste modulator.

Conditioned taste aversion learning in leptin-receptor-deficient db/db mice.

The db/db mouse has defective leptin receptors. The defects lead to impairments of leptin regulation of food intake and body weight, and result in the expression of diabetic symptoms such as hyperinsulinemia, hyperglicemia, and extreme obesity. Recent studies have proposed that leptin may also affect memory and learning processes.

Leptin and sweet taste.

Leptin, the product of the obese (ob) gene, is a hormone primarily produced in adipose cells, and also at smaller amounts in some other peripheral organs. It regulates food intake, energy expenditure, and body weight. Leptin is thought to promote weight loss, at least in rodents, by suppressing appetite and stimulating metabolism.
