6%) died within a median follow-up period of 10.2 years. The Cox proportional hazard regression adjusted for covariates and baseline BW showed that a higher rate of weight loss was associated with higher mortality. The hazard ratios were 2.02 (1.28-3.20), 1.77 (1.10-2.85), 1.00 (reference), and 1.11 (0.67-1.83) for the first, second, third (reference), and fourth quartiles, respectively. BW trajectories revealed a significant decrease in BW in non-survivors.

Weight loss elucidated by serial BW measurements every 6 months is significantly associated with higher mortality among HD patients.

Autism spectrum disorder (ASD) has attracted more attention as a lifelong neurodevelopmental disorder with a prevalence that is increasing yearly. Although the demand for primary care for ASD is rapidly expanding, there are many challenges that need to be faced. Here, the current status of primary care for ASD in China is described. i) Identification of and care for ASD includes pre-diagnosis, diagnosis and evaluation, and treatment; the complexity of the disease and the lack of public understanding increase delays in diagnosis and treatment. ii) Most instruments, which are indispensable for diagnosing and evaluating ASD, are of foreign origin. iii) Treatments for ASD are based on mainstream Western interventions with complementary approaches. iv) The scale of rehabilitation and educational institutions has gradually grown and their expertise has gradually increased but rehabilitation costs are relatively high.Over the past 30 years or so, the body of research on autism spectrum disorders (ASD) in China has grown steadily. With the tireless efforts of government agencies and private organizations, the legitimate rights and interests of children with ASD have been initially guaranteed through a series of education and rehabilitation reforms, yet there are still many challenges to overcome. Many quality studies on the prevalence of ASD have been conducted in recent years, but China has lacked official census data until now. Moreover, there is a general lack of awareness of ASD even among the groups that directly interact with individuals with ASD, namely parents/caregivers, teachers, and doctors. Despite that fact, ASD should be brought to the attention of professionals and policymakers so that they can take appropriate measures, which include i) early comprehensive screening and diagnosis of ASD, ii) improvement of the corresponding policies and regulatory system, and iii) promotion of public awareness of ASD.

Chronic diffuse sclerosing osteomyelitis (CDSO) is a non-suppurative inflammatory bone disease diagnosed based on combined clinical, histopathological, and radiological findings. Accurate diagnosis is important since CDSO is more refractory to treatment than suppurative osteomyelitis. The purpose of this study was to determine the diagnostic efficacy of diffusion-weighted imaging (DWI) in the quantitative assessment of CDSO to distinguish it from acute suppurative osteomyelitis (ASO) and chronic suppurative osteomyelitis (CSO) of the mandible.

Using a retrospective cohort study design, we analyzed MRI data of 6 patients with CDSO and 34 patients with ASO and CSO. The mean apparent diffusion coefficient (ADC) values of the three groups (CDSO, ASO, and CSO groups) were calculated, and differences were analyzed using Kruskal-Wallis and post-hoc Mann-Whitney tests with Bonferroni adjustments. We performed a receiver operating characteristic (ROC) curve analysis to evaluate the ability of the ADC to predict CDSO. P < 0.05 was considered statistically significant.

The mean ADCs in the CDSO, ASO, and CSO groups were 1.22 ± 0.04 × 10

/s, respectively. Significant differences were observed between the ASO and CSO groups (P < 0.001) and CSO and CDSO groups (P < 0.01). However, there was no significant difference between the ASO and CDSO groups (P = 0.21). The ROC analysis revealed a cut-off ADC value of 1.19 for distinguishing the CSO group from the CDSO group. Sensitivity, specificity, accuracy, and area under the ROC curve were 1.0, 0.92, 0, 95, and 0.94, respectively.

The results suggest that ADC may be useful in distinguishing CDSO from mandibular suppurative osteomyelitis.

High-dose glucocorticoids and cyclophosphamide are widely used for the treatment of NPSLE, but cyclophosphamide has a risk of cervical intraepithelial neoplasia and ovarian insufficiency, which may discourage its use in young women. We experienced a case of NPSLE with cerebral vasculitis and lupus nephritis that responded successfully to glucocorticoids and mycophenolate mofetil (MMF). MMF might be a treatment option for NPSLE without concern for reproductive toxicity. Etomoxir However, there are only a few reports on the efficacy of MMF in NPSLE, and further investigations are needed.Pulmonary artery pseudoaneurysms (PAPs) are rare but can cause massive hemoptysis if they rupture. Infectious PAPs are often treated by surgery or transcatheter embolization and are rarely treated conservatively with antibiotics. We herein report a case of PAP treated conservatively in a 21-year-old woman with lung abscess. Except for one massive hemoptysis early in the course, the patient responded well to the empirical therapy with ampicillin/sulbactam and systemic hemostatic agents. After six weeks of antibiotics, the pseudoaneurysm disappeared. Conservative therapy with careful observation can be considered in small infectious PAPs when there is a good clinical response to initial conservative therapy.We herein report a case of acute kidney injury (AKI) due to tubulointerstitial nephritis (TIN) after starting empagliflozin in a diabetic patient. The patient developed stage 1 AKI with proteinuria and elevated tubulointerstitial markers. A renal biopsy showed acute TIN with lymphocytic infiltration into the interstitium. The patient's renal function improved after discontinuation of empagliflozin and steroid administration. Sodium-glucose cotransporter 2 (SGLT2) inhibitor-induced AKI has been reported, but the underlying mechanism remains unclear, potentially because few patients with SGLT2-inhibitor-induced AKI have undergone a renal biopsy. We report the present case in the hope that it will help clarify the mechanism.We herein report a 44-year-old Japanese man with hereditary transthyretin amyloidosis (ATTRv amyloidosis) harboring the variant Leu58Arg (p.Leu78Arg) in TTR in whom we conducted an observational study with liver transplantation (LT) and transthyretin (TTR) stabilizers (tafamidis and diflunisal) for 9 years. This patient showed gradual deterioration of sensory, motor, and autonomic neuropathy symptoms after LT. Furthermore, cardiac amyloidosis gradually developed. Although the present case showed deterioration of the symptoms after disease-modifying treatments, LT might be suitable in patients with the same variant if they are young and in good condition due to a long survival after LT.A 28-year-old woman exhibited a spiking fever, arthritis, and liver disfunction when she was 22 weeks pregnant. She was diagnosed with adult-onset Still's disease (AOSD). As her condition was resistant to corticosteroid therapy, tocilizumab (TCZ) was selected. The TCZ treatment was effective, and she delivered a healthy child while receiving TCZ treatment. Cases in which AOSD first arises during pregnancy are rare, and there have been no reports of TCZ treatment for AOSD being initiated during pregnancy. Although the safety of TCZ treatment during pregnancy has not been established, it may be effective against severe AOSD that develops during pregnancy.We herein report a case of systemic sclerosis (SSc)-related pericarditis successfully treated with mycophenolate mofetil (MMF) and low-dose prednisolone (PSL). The patient was a 72-year-old woman with anti-centromere antibody. Her clinical manifestations were Raynaud phenomenon, bilateral pleural effusion, pericardial effusion and skin tightness. Based on the findings of exudative pericardial effusion with the absence of pulmonary arterial hypertension from the results of the cardiac catheter and pericardiocentesis, she was diagnosed with SSc-related pericarditis and treated with PSL10 mg and MMF 1 g per day, leading to the complete resolution of pericarditis. These findings suggested that MMF and low-dose PSL were effective for SSc-related pericarditis.We herein report a 72-year-old woman with rheumatoid vasculitis who exhibited a depressed level of consciousness after receiving the first dose of the Pfizer-BioNTech mRNA BNT162b COVID-19 vaccine and was diagnosed with meningoencephalitis. Although there was no confirmatory examination, the diagnosis was based on magnetic resonance imaging (MRI) findings and etiological assessments, including microbiological and autoimmune investigations. Both intravenous steroid pulse and gammaglobulin therapies alleviated the patient's symptoms, and the MRI findings improved. Although the efficacy of COVID-19 vaccination has been widely accepted, such neurologic complications might occur in patients with rheumatoid diseases or vasculitis syndromes.Lumbar hernias are extremely rare. The posterolateral abdominal wall has two susceptible areas - the superior (Grynfeltt-Lesshaft's triangle) and the inferior (Petit's triangle) lumbar triangles - that cause superior and inferior lumbar hernias, respectively. We herein report a 67-year-old woman with nephrotic-range proteinuria caused by primary superior lumbar hernia. Superior lumbar hernias should be considered as a differential disease causing massive orthostatic proteinuria in adults. The present case highlights the importance of considering lumbar hernia in patients with flank swelling and the potential complications that may result from a missed diagnosis.We herein report two patients with hepatocellular carcinoma (HCC) who exhibited intraabdominal bleeding caused by tumor rupture soon after lenvatinib initiation. A hypervascular nodule was present in the lateral segment manifesting extrahepatic protrusion in an 81-year-old-man and in the caudate lobe, which was completely occupied by the tumor, in an 83-year-old-man. Both patients were given lenvatinib, and epigastralgia occurred suddenly three and five days later. Computed tomography revealed high-attenuation areas suggesting bleeding around the left and caudate lobes. Considering the strong antiangiogenic effects by lenvatinib, transcatheter arterial embolization should be performed before lenvatinib initiation in patients with subcapsular HCC.Polyneuropathy, Organomegaly, Endocrinopathy, M-protein and Skin changes (POEMS) syndrome manifests as elevated levels of vascular endothelial growth factor (VEGF) and monoclonal gammopathy. We treated a case of POEMS syndrome showing monoclonality in both IgA-λ and IgG-κ. Serial renal biopsies before treatment and after normalization of the VEGF levels suggested that glomerular microangiopathy had developed due to VEGF, while biclonal gammopathy was not eliminated. The renal pathology, proteinuria, and renal function all clearly improved. Although severe polyneuropathy limited activities of daily living and enforced a bedridden state, the patient dramatically regained his motor function, achieving crutch walking after induction of remission. This case is highly notable due to the presence of biclonality and repeated biopsies.
