Association of physical activity with psychological distress and happiness in mothers of children with autism spectrum disorders during the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may have severely impacted the psychological status of mothers of children with autism spectrum disorder (ASD). Although a previous study reported that physical activity (PA) moderated psychological distress in parents of children with ASD during the COVID-19 pandemic, the effect of PA on the happiness levels of such parents during the pandemic remains unclear. This study investigated the associations among PA, psychological distress, and happiness in mothers of children with ASD during the COVID-19 pandemic. METHODS: This cross-sectional study was designed to evaluate mothers of children with disabilities. Questionnaires were collected from mothers living in Yamaguchi and Okayama Prefectures, Japan, between February and December 2022. During this period, three large waves of the COVID-19 pandemic occurred in Japan. Of the 601 respondents, 334 mothers had children with ASD and offered valid data. PA was assessed using the short form of the International Physical Activity Questionnaire. Psychological distress and happiness were assessed using the six-item Kessler Psychological Distress Scale (K6) and the Subjective Happiness Scale (SHS). RESULTS: The mothers had markedly higher K6 scores (6.49) and more than half of them had moderate-to-severe psychological distress, whereas the SHS scores (4.46) were similar to that of the general Japanese population. In a multivariable-adjusted model based on the analysis of covariance, the K6 score was not associated with any PA items. In contrast, SHS scores were positively associated with moderate-intensity PA (MPA) and total moderate- to vigorous-intensity PA (MVPA), independent of K6. In the post-hoc test, mothers who did some (4.52) or enough (≥ 150 min/week) MPA (4.56) had a higher SHS score than those who did not (4.09). Similarly, mothers who engaged in sufficient (≥ 600 MET-min/week) total MVPA had higher SHS scores (4.57) than those who did not engage in MVPA (4.12). CONCLUSIONS: The mothers of children with ASD during the COVID-19 pandemic had markedly higher psychological distress, though none of the PA items were associated with stress levels. However, PA was positively associated with happiness in mothers of children with ASD independent of their stress levels.

[A Case of Rapidly Growing Sarcomatoid Urothelial Carcinoma of the Renal Pelvis and Ureter].

75 year-old man followed up regularly for the treatment of lung cancer came to our hospital with a chief complaint of general malaise. Blood test results showed deterioration in the renal function, and computed tomography (CT) confirmed left hydronephrosis. He was admitted to the hospital with the diagnosis of obstructive pyelonephritis. Despite antibiotic therapy after the left ureteral stent placement, CT on day 19 of hospitalization showed an enlarged soft tissue shadow along the renal pelvis and ureter, which was suspected to be peripelvic urinary extravasation caused by stent occlusion. We decided that conservative treatment would not improve his condition and conducted surgical therapy considering the possibility of malignancy. Intraoperatively, viscous and fragile tumor affected the renal pelvis and ureter. The operation resulted in left nephrectomy because radical resection was impossible. The pathological diagnosis was sarcomatoid urothelial carcinoma of the renal pelvis with ureter origin. He died due to multipleorgan failureon day 20 after theope ration. Were port a caseof sarcomatoid urothelial carcinoma in the upper urinary tract that was difficult to diagnose preoperatively based on imaging studies.

Tufted-angioma-like lesion associated with vascular endothelial growth factor and interleukin-6 in TAFRO syndrome: Is it a common histological feature of multicentric Castleman disease/POEMS syndrome?

The histology of skin lesions of TAFRO (thrombocytopenia, anasarca, reticulin fibrosis/renal failure, and organomegaly) syndrome has rarely been reported. We report herein two cases of TAFRO syndrome with characteristic vascular skin lesions. The lesions resembled a tufted angioma, although those of case 1 partially resembled a glomeruloid hemangioma, which was known as a specific lesion in POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes), a variant of multicentric Castleman disease (MCD). The high titer of serum vascular endothelial growth factor and interleukin-6 could explain common characteristic vascular lesions in both TAFRO syndrome and POEMS syndrome/MCD.

Membranous glomerulonephritis with an LMNA mutation.

We had encountered the case of membranous glomerulonephritis (MGN) with dilated cardiomyopathy due to LMNA gene mutation. LMNA mutation was known as a cause of 'laminopathy' such as dilated cardiomyopathy, muscular dystrophy, neuropathy and so on. LMNA gene might be a candidate of genetic basis in cryptogenic MGN.

[A case report of suspected Stauffer syndrome presenting with fever, extensive inflammation, and abnormal liver function tests].

A man was referred to our hospital because of malaise and abnormal liver function tests. He had had a kidney removed for early renal cell carcinoma. We performed ultrasonography, CT scan, and liver biopsy, all of which were normal. However, FDG-PET revealed abnormal, diffuse uptake in the bone. A bone biopsy showed abnormal clear cells resembling renal cell carcinoma. Because there was no other primary origin, this histopathological finding led to the diagnosis of bone metastasis of renal cell carcinoma, and the abnormal liver function test was thus inferred to be due to Stauffer syndrome.

Hypereosinophilic syndrome as a cause of fatal thrombosis: two case reports with histological study.

Herein we present two cases of hypereosinophilic syndrome with a unique clinical presentation. One patient showed severe systemic thrombosis with splenic rupture and the other patient showed finger gangrene with various systemic symptoms. Both patients were examined histologically, and several characteristics were noted. First, fresh or organized thrombosis with marked eosinophilic infiltration was observed in the cavity and walls of the thrombosed vessels. Second, many eosinophils showed degranulation and were positive for eosinophilic cationic protein on immunohistological examination. Third, the structures of thrombosed vessels were well preserved, which is not observed in systemic vasculitis. These patients exhibited no neoplastic features and were treated with prednisolone with excellent therapeutic results.

Acquired generalized anhidrosis: review of the literature and report of a case with lymphocytic hidradenitis and sialadenitis successfully treated with cyclosporine.

We report a case of acquired generalized anhidrosis successfully treated with cyclosporine. A skin biopsy showed T cell infiltration around the sweat glands and labial biopsy revealed lymphoplasmacytic infiltration around the minor salivary gland, suggesting an underlying autoimmune disease such as Sjögren's syndrome. Administration of cyclosporine markedly improved the patient's condition and sympathetic skin response; thus cyclosporine may be effective for treating anhidrosis in patients with autoimmune disorders.

Renal biopsy cases in myeloproliferative neoplasms (MPN).

We performed renal biopsy in three cases complicated by myeloproliferative neoplasms (MPN). Although several cases of glomerulonephritis associated with MPN have been reported, the etiologies of the renal disorders were not established (Plomley et al., Aust NZ J Med, 13:125-129, 1983; Sharma et al., Nephron, 69:361, 1995; Kanauchi et al., Intern Med, 33:36-40, 1994; Kasuno et al., Nephrol Dial Transplant, 12:212-215, 1997; Au et al., Am J Kid Dis, 34:889-893, 1999; Kosch et al., Nephrol Dial Transplant, 15:1710-1711, 2000; Oymak et al., Nephron, 86:346-347, 2000; Chun et al., Am J Nephrol, 20:344-346, 2000; Chung et al., Am J Nephrol, 22:397-401, 2002; Asaba et al., Clin Exp Nephrol, 7:296-300, 2003; Haraguchi et al., Clin Exp Nephrol, 10:74-77, 2006; Saigusa et al., J Nephrol, 19:656-658, 2006; Okuyama et al., Clin Nephrol, 6:412-415, 2007; Nishi et al., Clin Nephrol, 5:393-398, 2010; Ulusoy et al., Intern Med, 49:2477, 2010). A review of previous reports of renal biopsy cases with MPN in the English literature suggested that circulation control is important for the treatment of renal disorders that mimic glomerulonephritis in MPN.

An autopsy case of Mycobacterium abscessus pulmonary infection complicated with rheumatoid arthritis.

We present the case of a 70-year-old man diagnosed with Mycobacterium abscessus pulmonary infection complicated with rheumatoid arthritis who was treated with corticosteroids. He died despite treatment according to the recommended regimen of imipenem, clarithromycin, and amikacin. Autopsy revealed granulomatous lesions throughout the bilateral lungs. We conclude that M. abscessus infection may have a fatal outcome because of the drug resistance of the pathogen. This case suggests that rheumatoid arthritis might be a risk factor for M. abscessus pulmonary infection, but further studies are necessary for clarification.
