Observational StudyPathohistological features of the aging human lacrimal gland.
To assess sex-related differences in the pathohistological features of the human lacrimal gland and to investigate age-related and sex-related differences in stereologically measured volume density of the secretory tissue, connective tissue, and fat. ⋯ Female lacrimal glands are more susceptible to degeneration, and this susceptibility could play an important role in the higher incidence of dry eye disease in older women. A further stereological analysis using more samples from younger age groups is needed to elucidate age-related and sex-related differences in the structure of the human lacrimal gland and their impact on dry eye disease.

Interleukin-2 gene methylation levels and interleukin-2 levels associated with environmental exposure as risk biomarkers for preterm birth.
To compare interleukin-2 levels (IL-2) and IL-2 gene site 1 methylation levels between preterm newborns (PN) and full-term newborns (FN) and investigate their association with the environmental exposure of their mothers during pregnancy. ⋯ IL-2 levels, hypomethylation of the IL-2 gene site 1, and the mother's rural residence (probably due to pesticide exposure) were predictive biomarkers for preterm birth. For the first time, we present the reference values for the methylation of IL-2 gene site 1 in PN and FN, which can be used in the clinical setting and biomonitoring.

Case ReportsClinical relevance of the TECTA c.6183G>T variant identified in a family with autosomal dominant hearing loss: a case report.
Missense variants in the α-tectorin gene (TECTA) cause autosomal dominant (DFNA8/A12) non-syndromic hearing loss (ADNSHL) and account for a considerable number of ADNSHL cases. According to genotype-phenotype correlation studies, missense variants in the zona pellucida (ZP) domain of α-tectorin predominantly cause mid-frequency HL. Here, we report on clinical exome sequencing results in a large family with early-onset, sensorineural, moderate-to-severe mid-frequency HL. ⋯ On the basis of specific segregation in the currently studied family and the general guidelines of the American College of Medical Genetics and Genomics, we argue that the TECTA c.6183G>T variant should be considered a likely pathogenic cause of ADNSHL. This report adds to the knowledge on the rare c.6183G>T missense variant, which affects the immediate vicinity of the ZP domain in TECTA. Our findings highlight the importance of clinical evaluation in patients with familial HL and of studying family segregation when assessing the pathogenicity of a variant.

Increased carotid intima-media thickness is associated with higher odds of unfavorable outcomes in adults without advanced vascular diseases presenting with non-severe COVID-19 pneumonia: a nested case-control study.
To evaluate the association between carotid intima-media thickness (CIMT) at hospital admission and unfavorable outcomes in adults without advanced vascular diseases presenting with non-severe COVID-19 pneumonia to assess the feasibility of evaluating CIMT as a risk stratification aid in this setting. ⋯ This study supports the feasibility of CIMT as a risk stratification aid in adults free of advanced vascular disease presenting with non-severe COVID-19 pneumonia.

Case ReportsThe first case report of distal 16p12.1p11.2 trisomy and proximal 16p11.2 tetrasomy inherited from both parents.
Recurrent copy number variants in the chromosomal region 16p11.2 are among the most frequent genetic causes of neurodevelopmental disorders. The increasing prevalence of brain structural anomalies is also associated with 16p11.2 deletions and duplications. We report on a four-year-old boy with microcephaly, trigonocephaly, and dysmorphic features. ⋯ Double duplications are very rare chromosomal rearrangements. The phenotype for distal 16p12.1p11.2 trisomy (BP1-BP3) and proximal 16p11.2 (BP4-BP5) tetrasomy is unknown. To our knowledge, this is the first patient described in the literature who inherited 16p11.2 duplications from both parents.
