Complete loss of E-cadherin expression was observed in approximately a quarter of both SRCHCs as well as in all ILC cases. PIK3CA mutations were detected in all three sequenced cases (two axillary SRCHCs and one eyelid SRCHC).

The histopathological, immunohistochemical, and genetic findings suggest that both SRCHCs are phenotypic variants of AC, although there are differences in sex, macroscopic findings, and the frequency of lymph node metastasis among the three. In contrast, ILC differs from the three tumour types.

The hypothalamic-pituitary-gonadal (HPG) axis governs sexual maturation and reproductive function in humans. In early postnatal life, it is transiently active during which circulating sex steroids reach adult levels. While this so-called minipuberty represents a universal phenomenon in infants of both sexes, its role for early maturation and growth remains incompletely understood.

To provide normative data on auxology as well as serum and urinary hormone levels in healthy, full-term infants throughout the first year of life and to investigate associations of postnatal HPG axis dynamics as well as hormonal, genetic and environmental exposures with early genital development and growth.

Healthy, Danish, full-term, singleton newborns including their parents.

Single-centre, prospective, observational longitudinal pregnancy and birth cohort.

Newborns were followed with six repeated clinical examinations during a one-year follow-up period. An umbilical cord blood sample was drawn at birth. At each visit, ire in healthy infants including additional data in their parents.

The COPENHAGEN Minipuberty Study provides detailed, longitudinal data on early genital development and growth including hormonal and genetic profiles and environmental exposure in healthy infants including additional data in their parents.

Preclinical studies of MR309, a selective sigma1 receptor (σ1R) antagonist, support a potential role in treating neuropathic pain. We report two studies that provide insight into the pharmacokinetics (PK) and brain σ1R binding of MR309.

Steady-state PK of MR309 (400 mg QD and 200 mg BID for 10 days; EudraCT 2015-001818-99 [PK study]) and the relationship between MR309 plasma exposure and brain σ1R occupancy (EudraCT 2017-000670-11 [PET study]) were investigated in healthy volunteers. Positron emission tomography (PET) using the σ1R ligand [

C]SA4503 was conducted at baseline, 2h and 8h after a single dose of MR309 (200-800 mg). The relationship between brain σ1R occupancy and MR309 exposure was explored using data-driven model fitting.

MR309 was well tolerated, brain σ1R occupancy ranged between 30.5% and 74.9% following single-dose MR309 (n=7). MR309 BID provided a plasma PK profile with less fluctuation than QD dosing (n=16). MR309 200 mg BID yielded average steady state plasma concentrations between 2000 and 4000 ng/mL in the PK study, which corresponded to an estimated brain σ1R occupancy of 59-74%.

MR309 200 mg BID dose was below the 75% σ1R occupancy threshold expected to elicit maximal antinociceptive effect as observed in neuropathic pain models. Further investigations of MR309 for neuropathic pain will require higher brain σ1R occupancy, and establish the optimal dose by elucidating the clinical impact of a broad range of brain σ1R occupancy across different neuropathic pain indications.

However, characteristics of the remission and relapse following the withdrawal of omalizumab remain largely unknown. We aimed to define the characteristics of remission in CSU following omalizumab with gradually lengthened dosing intervals in this retrospective study of 102 patients who were treated with at least 3 doses of omalizumab between 2013 and 2020. Of 102 patients, 70 (68.6%) showed a CR to omalizumab at standard doses. Omalizumab could be discontinued in 47 of 70 patients using gradually lengthened dosing intervals. Following a mean follow-up duration of 12.2 months, 25 (58.1%) patients were still in remission while 18 (41.9%) had relapse (Follow-up data were not available in 4 patients). The relapses were unresponsive to antihistamines in 14 patients (77.7%), however, re-treatment with omalizumab led to complete control of symptoms. The patients younger than 40 were more likely to relapse. Despite the need for comparison with fixed-dosing intervals in larger, prospective studies, the results of this study imply that omalizumab with gradually extended dosing intervals might provide a long duration of remission in CSU.

Clear cell (hemangioblastoma-like) stromal tumor of the lung is a newly described, rare pulmonary neoplasm. Recurrent YAP1-TFE3 gene fusions have recently been reported in three cases. We describe two additional cases and confirm the characteristic YAP1-TFE3 gene fusion.

Two mesenchymal tumors of lung were identified from our soft tissue pathology consultation service and RNA sequencing was performed. Both cases were in male patients, aged 35 and 77 years old. Both presented as solitary lung nodules measuring 3.9 and 7.5 cm in greatest dimension. Thapsigargin price Histopathologically, the tumors were composed of epithelioid to plump spindled cells arranged in packets and solid sheets. The cells showed fusiform to ovoid nuclei with open chromatin, variably prominent nucleoli, and scant to moderate, clear to eosinophilic cytoplasm. Cytologic atypia and significant mitotic activity were minimal. None of the tumors expressed lineage-specific immunophenotypic markers. Both cases were diffusely positive for nuclear TFE3. Unlike YAP1-TFE3 fused epithelioid hemangioendothelioma, for which the fusion breakpoint occurs in YAP1 exon 1 and TFE3 exons 4 or 6, the fusion breakpoints of these tumors are located in YAP1 exon 4 and TFE3 exon 7.
