To clarify the association between lifestyle changes as a result of coronavirus disease 2019 containment measures and changes in metabolic and glycemic status in patients with diabetes, a cross‐sectional, single‐center, observation study was carried out. A self‐reported questionnaire was provided to ascertain the frequency of various lifestyle activities before and after the coronavirus disease 2019 containment measures in Japan. Among 463 patients, change in glycated hemoglobin was significantly associated with change in bodyweight. After stratification by age 65 years, binary logistic regression analysis showed that increased frequency of snack eating increased bodyweight (odds ratio 1.709,
P
= 0.007) and glycated hemoglobin (odds ratio 1.420,
P
= 0.025) in the younger group, whereas in the older patients, reduced walking activities resulted in weight gain (odds ratio 0.726,
P
= 0.010). In conclusion, changes in eating behavior and physical activity increased bodyweight and reduced glycemic control among diabetes patients, but by different processes depending on age under the coronavirus disease 2019 containment measures in Japan.
To clarify the clinicopathological features of X-linked hydrocephalus, the authors studied 30 affected males from 15 families. In utero ultrasonography, performed at 21 to 40 weeks of gestation, revealed 18 fetuses with hydrocephalus. Computerized tomography (CT) revealed bilateral enlargement of the lateral ventricle with preponderant dilation of the posterior horn. In five patients with complete magnetic resonance (MR) imaging data, the most specific finding was localized atrophy of the anterior vermian lobe. Other MR imaging findings included a large massa intermedia, flat corpora quadrigemina, a small brainstem, and diffuse hypoplasia of the cerebral white matter. In all cases, the corpus callosum was hypoplastic or aplastic. The aqueduct was patent in four of five cases. Asymmetrical reduction of the ventricular size and a rippled ventricular wall were characteristic postshunt CT findings. Progressive macrocephaly and symptoms due to increased intracranial pressure were ameliorated by the shunt; however, the neurological outcome was not improved by shunting. Of 14 patients who lived to be between 2 and 18 years of age, all are retarded. These results indicate that X-linked hydrocephalus is not a disease of simple ventriculomegaly due to aqueduct stenosis alone but involves other complicated central nervous system anomalies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
