AI Article Synopsis

  • Human caliciviruses, especially norovirus genotype GII.4, are significant causes of viral diarrhea in children, as highlighted by a study in China.
  • Among 295 children with acute diarrhea, 10.85% tested positive for HuCV, with most being HBGA secretors or partial secretors, while only a small percentage of asymptomatic children tested positive.
  • The findings suggest that blood type O may be linked to a higher risk of GII.3 infection, but due to the small sample size, additional research is needed for confirmation.

Article Abstract

Human caliciviruses (HuCVs) have been recognized as a major cause of sporadic viral diarrhea in children, among which norovirus genotype GII.4 is the most prevalent genotype. Stool and saliva samples were collected from 295 children with acute diarrhea and 150 asymptomatic children at a hospital in China. The HuCV detection rate was 10.85% (32/295) among the children with acute diarrhea, and all of these 32 children were either HBGA secretors (12/32) or partial secretors (20/32). HuCV was detected in two (1.33%) of the 150 samples obtained from the asymptomatic children. Of the norovirus-GII.3-positive children, 60% had blood type O, but only 17.29% of the symptomatic patients had blood type O, indicating that type O individuals could be at higher risk of GII.3 infection. However, due to the limited number of individuals in this study, further studies with a larger number of subjects should be conducted to verify this hypothesis.

Background: Type 1 diabetes is a serious, chronic disorder with an increasing incidence among children and adolescents. Glycemic control in individuals with type 1 diabetes is better managed through a basal-bolus regimen with either regular human or rapid-acting insulin analogues administered as a bolus at mealtimes. Rapid-acting insulin analogues have been hypothesized to cause optimal glycemic control and less risk of hypoglycemic episodes compared to regular human insulins.

Background: Archetypes are representations of a group of people with shared behaviors, attitudes, and characteristics. The design and use of archetypes have potential application to increase partnership and support when embedding and scaling interventions but methodological approaches have not been developed.

Objective: To describe the methodology of designing archetypes for use in a pragmatic trial of advance care planning in the primary care context, SHARING Choices ((NCT04819191).

Background: Sow longevity and reproductivity are essential in the modern swine industry. Although many studies have focused on the genetic and genomic factors for selection, little is known about the associations between the microbiome and sows with longevity in reproduction.

Results: In this study, we collected and sequenced rectal and vaginal swabs from 48 sows, nine of which completed up to four parities (U4P group), exhibiting reproductive longevity.

Buprenorphine and postpartum contraception utilization among people with opioid use disorder: a multi-state analysis.

Addict Sci Clin Pract

Departments of Family and Community Medicine and Health and Clinical Outcomes Research, Saint Louis University School of Medicine, Saint Louis, MO, USA.

Background: The postpartum period provides an opportunity for birthing people with opioid use disorder (OUD) to consider their future reproductive health goals. However, the relationship between the use of medication for opioid use disorder (MOUD) and contraception utilization is not well understood. We used multistate administrative claims data to compare contraception utilization rates among postpartum people with OUD initiating buprenorphine (BUP) versus no medication (psychosocial services receipt without MOUD (PSY)) in the United States (US).

Recent genomic studies have allowed the subdivision of intracranial ependymomas into molecularly distinct groups with highly specific clinical features and outcomes. The majority of supratentorial ependymomas (ST-EPN) harbor ZFTA-RELA fusions which were designated, in general, as an intermediate risk tumor variant. However, molecular prognosticators within ST-EPN ZFTA-RELA have not been determined yet.
