Advancing Newborn Screening Long-Term Follow-Up: Integration of -Based Registries, Dashboards, and Efficient Workflows.

The Connecticut Newborn Screening (NBS) Network, in partnership with the Connecticut Department of Public Health, strategically utilized the electronic health record (EHR) system to establish registries for tracking long-term follow-up (LTFU) of NBS patients. After launching the LTFU registry in 2019, the Network obtained funding from the Health Resources and Services Administration to address the slow adoption by specialty care teams. An LTFU model was implemented in the three highest-volume specialty care teams at Connecticut Children's, involving an early childhood cohort diagnosed with an NBS-identified disorder since the formation of the Network in March 2019.

Presenting ADAMTS13 antibody and antigen levels predict prognosis in immune-mediated thrombotic thrombocytopenic purpura.

Immune-mediated thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder caused by antibodies against ADAMTS13. From the United Kingdom TTP registry, we undertook a prospective study investigating the impact of the presenting anti-ADAMTS13 IgG antibody and ADAMTS13 antigen on mortality. A total of 312 episodes involving 292 patients over 87 months were included; 68% were female, median age 46 (range, 11-88 years), and median presenting ADAMTS13 of <5% (range, <5%-18%).

The utility of ADAMTS13 in differentiating TTP from other acute thrombotic microangiopathies: results from the UK TTP Registry.

Thrombotic microangiopathies (TMAs) are frequently difficult to differentiate clinically, and measurement of ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) remains vital in thrombotic thrombocytopenic purpura (TTP) diagnosis. We retrospectively reviewed cases referred for ADAMTS13 testing, using UK TTP Registry screening data. Of a total 810 cases, 350 were confirmed as TTP.

Use of hydrogel breast biopsy tissue markers reduces the need for wire localization.

Background: The purpose of this study was to determine whether breast biopsy tissue markers composed of an ultrasound-visible hydrogel reduced the need for preoperative wire localization (WL) in patients undergoing a partial mastectomy.

Methods: A single-surgeon, single-institution, retrospective chart review was performed on 691 consecutive female patients, with mean age 67 years (range 36-98 years), from 2009 to 2012 undergoing partial mastectomies after percutaneous biopsies by stereotactic or ultrasound guidance.

Results: Overall, the use of WL was more frequent in patients who had standard (other) markers placed during biopsy as opposed to those with hydrogel markers (HydroMARK).

Discovery of a novel mechanism of steroid receptor antagonism: WAY-255348 modulates progesterone receptor cellular localization and promoter interactions.

WAY-255348 is a potent nonsteroidal progesterone receptor (PR) antagonist previously characterized in rodents and nonhuman primates. This report describes the novel mechanism by which WAY-255348 inhibits the activity of progesterone. Most PR antagonists bind to and block PR action by inducing a unique "antagonist" conformation of the PR.

Pathways activated during human asthma exacerbation as revealed by gene expression patterns in blood.

Background: Asthma exacerbations remain a major unmet clinical need. The difficulty in obtaining airway tissue and bronchoalveolar lavage samples during exacerbations has greatly hampered study of naturally occurring exacerbations. This study was conducted to determine if mRNA profiling of peripheral blood mononuclear cells (PBMCs) could provide information on the systemic molecular pathways involved during asthma exacerbations.

Treatment with rhBMP12 or rhBMP13 increase the rate and the quality of rat Achilles tendon repair.

Tendon injuries that result in partial or complete tears often come from chronic, repetitive use, or from sudden trauma. In some cases, torn tendons can be repaired, but such repairs often fail to completely restore tendon function. We used global gene expression profiling and histological examination to study tendon repair to elucidate key molecular processes that regulate the rate and quality of tissue restoration.

Innate immune responses to TREM-1 activation: overlap, divergence, and positive and negative cross-talk with bacterial lipopolysaccharide.

TREM-1 (triggering receptor expressed on myeloid cells-1) is an orphan immunoreceptor expressed on monocytes, macrophages, and neutrophils. TREM-1 associates with and signals via the adapter protein DAP12/TYROBP, which contains an ITAM. TREM-1 activation by receptor cross-linking has been shown to be proinflammatory and to amplify some cellular responses to TLR ligands such as bacterial LPS.

Risk factors associated with beta-amyloid(1-42) immunotherapy in preimmunization gene expression patterns of blood cells.

Background: A phase 2a, double-blind, placebo-controlled, multicenter study was conducted to evaluate safety, tolerability, and pilot efficacy of immunization with beta-amyloid((1-42)) in patients with Alzheimer disease. Six immunizations were planned but were halted when meningoencephalitis was recognized as an adverse event in 6% of immunized patients.

Objective: To identify biomarkers associated with both the risk of meningoencephalitis and antibody responsiveness.
