Worsening of myasthenic symptoms associated with statins.

Introduction/aims: The common presentations of statin intolerance are muscle-specific symptoms. Although statins are one type of drug reported to cause myasthenic worsening, myasthenic worsening has not been recognized as statin intolerance. The purpose of the present study is to investigate in a large cohort the safety profiles of statins in patients with myasthenia gravis (MG).

Taste disorders and alopecia in myasthenia gravis.

Background: Non-motor symptoms in myasthenia gravis (MG) are rarely confirmed. Although there are some small cohort studies, a large-systemic survey has not yet been performed.

Methods: We investigated the incidence and clinical characteristics of patients with MG who had taste disorders and alopecia using data of 1710 patients with MG enrolled in the Japan MG Registry 2021.

Streptococcus agalactiae Meningitis in an Immunocompetent Adult: A Case Report and Literature Review.

Streptococcus agalactiae is a rare cause of meningitis in healthy adults. We herein report a case of culture-negative Streptococcus agalactiae meningitis in a healthy adult which was diagnosed using the FilmArray Meningitis and Encephalitis Panel. A healthy 22-year-old man presented with a fever, headache, and neck stiffness.

Effectiveness of early cycles of fast-acting treatment in generalised myasthenia gravis.

Background: Early fast-acting treatment (EFT) is the aggressive use of fast-acting therapies such as plasmapheresis, intravenous immunoglobulin and/or intravenous high-dose methylprednisolone (IVMP) from the early phases of treatment. EFT is reportedly beneficial for early achievement of minimal manifestations (MM) or better status with ≤5 mg/day prednisolone (MM5mg), a practical therapeutic target for myasthenia gravis (MG).

Objective: The current study aimed to clarify which specific EFT regimen is efficacious and the patient characteristics that confer sensitivity to EFT.

Impact of Early Treatment with Intravenous High-Dose Methylprednisolone for Ocular Myasthenia Gravis.

The efficacy of intravenous high-dose methylprednisolone (IVMP) in ocular myasthenia gravis (MG) has not been fully established. This study aimed to elucidate the effects of early intervention with IVMP for achieving the therapeutic targets (minimal manifestations [MM] or MM or better status with prednisolone ≤ 5 mg/day [MM5mg]) in ocular MG. In this observational study, we included a total of 1710 consecutive patients with MG enrolled in the Japan MG Registry in 2021.

Meat consumption and consumer attitudes in Japan: An overview.

Among Asian countries, Japan has the shortest history of eating meat in its food culture. It was only after 2007 that household fresh meat consumption surpassed fresh fish consumption in Japan. Although it was forecast that slowing population and economic growth would limit the demand for meat, household meat consumption in 2020 increased remarkably from that in 2019, perhaps due to COVID-19.

Guillain-Barre Syndrome Caused by Mycoplasma pneumoniae Infection in an Elderly Patient Initially Misdiagnosed As Frailty.

A 73-year-old man with a history of hypertension was referred to our department because of progressive frailty while being treated for acute heart failure. Physical examination revealed loss of tendon reflexes in the lower extremities and muscle weakness in all extremities. After close examination, he was diagnosed with Guillain-Barre syndrome (GBS), which was preceded by a Mycoplasma pneumoniae infection.

Estimation of discrimination threshold for emulsified chicken oil in chicken broth.

Although fat content affects the texture and flavor of meat and meat products, the fat discrimination thresholds are unknown. This study aimed to elucidate the discrimination threshold of fat in meat products using broth from chicken thigh meat as a meat taste model. In Experiment 1, triangle tests were conducted between 1%, 0.

Epstein-Barr Virus-induced Meningitis-Retention Syndrome.

Unlabelled: Meningitis-retention syndrome (MRS) is a rare disorder where aseptic meningitis is accompanied by urinary retention, which can be easily misdiagnosed as urinary tract infection. We present the case of a 55-year-old man with fever and dysuria. At the time of hospitalization, the patient had no symptoms of meningitis, but signs of meningeal irritation appeared later during the course of the disease.

Myelin oligodendrocyte glycoprotein-IgG-positive, steroid-responsive combined central and peripheral demyelination with recurrent peripheral neuropathy.

Myelin oligodendrocyte glycoprotein (MOG)-IgG detected by the cell-based assay is associated with demyelinating diseases of the central nervous system, such as optic neuritis, myelitis, and acute disseminated encephalomyelitis, but rarely with peripheral neuropathy. Here, we describe the case of a 32-year-old MOG-IgG woman who developed central and peripheral demyelinating lesions. In contrast to previous similar cases, she uniquely presented with repeated subsequent relapses in the peripheral nerve, mimicking chronic inflammatory demyelinating polyneuropathy.

[MPO-ANCA-associated hypertrophic pachymeningitis with monoclonal gammopathy of undetermined significance: a case report].

A 66-year-old woman presented with dysesthesia over the right side of her face, hypoglossal nerve dysfunction, dysphagia, and dysgeusia of the right side. A MRI scan of the brain revealed cerebral dural thickening on the right side of the skull base, and histopathological examination revealed granulomatous inflammation of the dura. Based on paranasal sinusitis, bronchodilatation, laboratory tests showing weakly positive MPO-ANCA, intact renal function, and the patient's favorable response to steroids, we diagnosed the patient with limited granulomatosis with polyangiitis (GPA).

Reduction in dietary lysine increases muscle free amino acids through changes in protein metabolism in chickens.

Taste is crucial to meat quality, and free Glu is an important taste-active component in meat. Our recent study showed that the short-term feeding of a low-Lys diet increases the concentration of free Glu and other free amino acids in chicken muscle and improves its taste. Here, we investigated the mechanisms by which the feeding of a low-Lys diet increases free Glu in chicken muscle.

[Intravascular large B-cell lymphoma with multiple intracranial hemorrhages diagnosed by brain biopsy].

Central nervous system intravascular lymphoma sometimes includes multiple lesions mimicking cerebral infarction. Herein, we report our experience with a case of intravascular large B-cell lymphoma (IVLBCL) with multiple hemorrhages. A 53-year-old woman was admitted to our hospital with clonic convulsions of the left upper limb.

Descriptive Sensory Traits of Cooked Eggs Laid from Hens Fed Rice Grain.

Descriptive sensory characteristics of eggs produced by conventional corn-based feeding and unhulled whole rice grain-feeding were compared in two cooking procedures using a trained panel. Rice-feeding significantly decreased brothy and roasted odor in eggs cooked into half-cooked egg yolks, and decreased the creamy odor, smoothness and moisture of eggs cooked into custard puddings. However, a statistical interaction between rice-feeding and production farm was not observed in every sensory attribute.

Peculiar Unpleasant Dysgeusia as the Sole Initial Symptom of Guillain-Barré Syndrome.

Dysgeusia is rare in Guillain-Barré syndrome, particularly as the initial symptom. We herein report the case of a 59-year-old woman who presented with only dysgeusia as the initial symptom of Guillain-Barré syndrome, followed by gradually worsening muscle weakness and bilateral sensory disturbances in the extremities. Her dysgeusia was so unpleasant that she could not eat anything, so she received nasogastric tube feeding without dysphasia.

Assessment of the dynamics of sensory perception of Wagyu beef strip loin prepared with different cooking methods and fattening periods using the temporal dominance of sensations.

In this study, we assessed the relative sensory perception of Wagyu beef using temporal dominance of sensations (TDS), which is a dynamic sensory method that captures the "dominance of sensation" throughout food consumption. In addition, we checked the integrity of the TDS by comparing the TDS results with a physicochemical analysis. Strip loins were obtained from 24- and 28-month-old Japanese Black cattle ("Wagyu") and were cooked by grilling () or boiling ().

Relative contribution of sensory characteristics for different types of pork loin, assessed by temporal dominance of sensations.

Background: Sensory perception is a dynamic process occurring sequentially. The dynamic analysis of the perception of sensory characteristics in meat is important to understand complex meat sensory characteristics. Temporal dominance of sensations (TDS) is a dynamic sensory method that captures the 'dominance of sensations' throughout food consumption, and it is possible to calculate the relative contribution of various sensory characteristics by 'dominance rate' over time.

Acute Intracranial and Spinal Subdural Hematoma Associated with Vardenafil.

A 28-year-old healthy man was admitted to our hospital because of right-sided headache, vomiting, and lower back pain after the administration of vardenafil. Computed tomography and magnetic resonance imaging of the brain showed a small, right-sided, subdural hematoma. A lumbar magnetic resonance imaging showed a longitudinally extended subdural hematoma.

In situ characterization of acidic and thermal protein denaturation by infrared microspectroscopy.

Foods meet acid pH during gastric digestion after cooking. An in situ infrared microspectroscopy approach was developed to detect the effects of heat and acid treatments on protein structure separately. Infrared spectra were obtained from meat samples treated with heat and/or acid, and wavenumbers accounting independently for the treatments were extracted by principal component regression.

Relationship between water-holding capacity and intramuscular fat content in Japanese commercial pork loin.

Objective: The relationship between water-holding capacity (WHC) and intermuscular fat (IMF) was studied in Japanese commercial pork.

Methods: Longissimus muscles of pigs (n = 62), obtained from two meat packing plants, were analyzed for IMF content, moisture content, drip loss, cooking loss, and pH. Pairwise relationships among these traits were determined using correlation analyses.

Reduction of dietary lysine increases free glutamate content in chicken meat and improves its taste.

Taste is a crucial factor of meat quality, and amino acids are important taste-active components in meat. Here, the effects of dietary lysine (Lys) content on taste-active components in meat, especially free glutamate (Glu), were investigated. Twenty-eight-day-old broilers (Gallus gallus) were fed diets with graded Lys content of 90% or 100% of the recommended Lys requirement, (according to the National Research Council, ) for 10 days.

Effect of dietary histidine on contents of carnosine and anserine in muscles of broilers.

Carnosine (β-alanyl-L-histidine) and anserine (β-alanyl-1-methyl-L-histidine) are dipeptides mainly found in skeletal muscle and brain of many vertebrates, and particularly high concentrations are observed in chicken pectoral muscles. It was reported that these peptides have many functions, such as antioxidant activity. In this study, we examined the effect of different levels of dietary histidine on carnosine and anserine contents in broiler muscles.

Regulation of free glutamate content in meat by dietary lysine in broilers.

Regulation of taste is important for improving meat quality and glutamate (Glu) is one of the important taste-active components in meat. Here, the effects of dietary lysine (Lys) content on taste-active components in meat, especially free Glu, were investigated. Fourteen-day-old broiler chicks (Gallus gallus) were fed on diets containing 100% or 150% of the recommended Lys content for 10 days.
