Eur J Pediatr

September 2021

Division of Neonatology, Department of Pediatrics, Amsterdam UMC, Location VU University Medical Center, De Boelelaan 1117, 1081, HV, Amsterdam, The Netherlands.

In this study, we aimed to (a) evaluate postnatal changes in bone development in relation to growth and (b) to determine factors associated with bone development, from birth to 24 months of corrected age. The metacarpal speed of sound (mcSOS) and metacarpal bone transmission time (mcBTT) were used to evaluate bone development in 98 preterm infants, during hospitalization and follow-up. The mcSOS and mcBTT values not only declined in the first 6 weeks of hospitalization but also during follow-up.

A major complication of primary Sjögren's syndrome (pSS) is development of mucosa associated lymphoid tissue (MALT) B-cell lymphoma, particularly in salivary glands. These lymphomas express FcRL4 and are characteristically associated with lymphoepithelial lesions. Neoplastic B-cells may be derived from non-neoplastic glandular intraductal B-cells, also virtually all expressing FcRL4.

Background: Medication non-adherence is associated with poor health outcomes and increased health care costs. Depending on definitions, reported non-adherence rates in cancer patients ranges between 16 and 100%, which illustrates a serious problem. In malignancy, non-adherence reduces chances of achievement of treatment response and may thereby lead to progression or even relapse.

Objective: Among autoimmune diseases, Sjögren's syndrome (SS) is most strongly associated with the development of malignant B cell lymphoma, in particular mucosa-associated lymphoid tissue (MALT)-type lymphoma. Previously, we have shown that in ∼40% of cases of salivary gland MALT lymphoma, high-affinity stereotypic rheumatoid factor (RF) B cell receptors, specific for IgG-Fc, are expressed. This study was undertaken to investigate whether in the inflamed salivary glands of patients with SS, a similar RF-biased Ig repertoire is present.

Objective: Findings from previous studies have suggested that subclinical inflammation of the synovium does not coincide with the appearance of rheumatoid arthritis (RA)-specific autoantibodies. This study was undertaken to examine the relationship between the presence of autoantibodies, changes in the synovium, and development of arthritis over time in a markedly larger, prospective study.

Methods: Fifty-five individuals who were IgM rheumatoid factor positive and/or anti-citrullinated protein antibody (ACPA) positive (detected by the anti-cyclic citrullinated peptide antibody test) and who were without any evidence of arthritis upon physical examination were included in the study.
