The extent to which semi-quantitative antibody levels confer protection against SARS-CoV-2 infection in populations with heterogenous immune histories is unclear. Two nested case-control studies were designed within the multisite HEROES/RECOVER prospective cohort of frontline workers to study the relationship between antibody levels and protection against first-time post-vaccination infection and reinfection with SARS-CoV-2 from December 2021 to January 2023. All participants submitted weekly nasal swabs for rRT-PCR testing and blood samples quarterly and following infection or vaccination.

Background: While there is evidence that COVID-19 vaccination protects against development of post-COVID conditions (PCC) after severe infection data are limited on whether vaccination reduces the risk after cases of less-severe non-hospitalized COVID-19 disease with more recent SARS-CoV-2 variant viruses. This study assessed whether COVID-19 vaccination was protective against subsequent development of PCC in persons with predominantly mild initial infections during both Delta and Omicron variant predominance.

Methods: This study utilized a case-control design, nested within the HEROES-RECOVER cohort.

Supported by a large body of work demonstrating the impact of infant attachment representations on subsequent development, numerous therapeutic programs have been developed to promote secure attachment, with increasing focus on parental mentalizing. Nonetheless, empirical evidence supporting their effectiveness has yet to be fully established. The current pilot study (N = 24) was designed to evaluate whether and to what extent parents' shifts in parental mentalizing following a brief attachment-based group intervention, namely circle of security parenting (COSP; Cooper, Hoffman & Powell, 2009) can be captured using the parental embodied mentalizing instrument (PEM; Shai & Belsky, 2017).

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous throughout the United States. Previous studies have shown PFAS exposure to be associated with a reduced immune response. However, the relationship between serum PFAS and antibody levels following SARS-CoV-2 infection or COVID-19 vaccination has not been examined.

Background: Data on antibody kinetics are limited among individuals previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). From a cohort of healthcare personnel and other frontline workers in 6 US states, we assessed antibody waning after messenger RNA (mRNA) dose 2 and response to dose 3 according to SARS-CoV-2 infection history.

Methods: Participants submitted sera every 3 months, after SARS-CoV-2 infection, and after each mRNA vaccine dose.

Importance: Data on the epidemiology of mild to moderately severe COVID-19 are needed to inform public health guidance.

Objective: To evaluate associations between 2 or 3 doses of mRNA COVID-19 vaccine and attenuation of symptoms and viral RNA load across SARS-CoV-2 viral lineages.

Design, Setting, And Participants: A prospective cohort study of essential and frontline workers in Arizona, Florida, Minnesota, Oregon, Texas, and Utah with COVID-19 infection confirmed by reverse transcriptase-polymerase chain reaction testing and lineage classified by whole genome sequencing of specimens self-collected weekly and at COVID-19 illness symptom onset.

Children's cognitive and language development is a central aspect of human development and has wide and long-standing impact. The parent-infant relationship is the chief arena for the infant to learn about the world. Studies reveal associations between quality of parental care and children's cognitive and language development when the former is measured as maternal sensitivity.

Background: Maternal depression and anxiety in the perinatal period affect the quality of maternal sensitivity and mentalizing abilities. Few studies analyzed implicit mentalizing in relation to maternal distress. The aims of the study were: to examine the relation between nonverbal mentalizing - parental embodied mentalizing (PEM) - and maternal depression and anxiety, verbal mentalizing, and maternal styles of interaction; and to test PEM as a mediator of the effect of maternal distress on styles of interaction.

The BNT162b2 (Pfizer-BioNTech) mRNA COVID-19 vaccine was recommended by CDC's Advisory Committee on Immunization Practices for persons aged 12-15 years (referred to as adolescents in this report) on May 12, 2021, and for children aged 5-11 years on November 2, 2021 (1-4). Real-world data on vaccine effectiveness (VE) in these age groups are needed, especially because when the B.1.

Background: We sought to evaluate the impact of changes in estimates of COVID-19 vaccine effectiveness on the incidence of laboratory-confirmed infection among frontline workers at high risk for SARS-CoV-2.

Methods: We analyzed data from a prospective frontline worker cohort to estimate the incidence of COVID-19 by month as well as the association of COVID-19 vaccination, occupation, demographics, physical distancing, and mask use with infection risk. Participants completed baseline and quarterly surveys, and each week self-collected mid-turbinate nasal swabs and reported symptoms.

Background: Data on the development of neutralizing antibodies (nAbs) against SARS-CoV-2 after SARS-CoV-2 infection and after vaccination with mRNA COVID-19 vaccines are limited.

Methods: From a prospective cohort of 3975 adult essential and frontline workers tested weekly from August 2020 to March 2021 for SARS-CoV-2 infection by reverse transcription-polymerase chain reaction assay irrespective of symptoms, 497 participants had sera drawn after infection (170), vaccination (327), and after both infection and vaccination (50 from the infection population). Serum was collected after infection and each vaccine dose.

Parental Embodied Mentalizing (PEM) captures the parent's capacity to extrapolate the child's mental states from movement and respond on a nonverbal level. Little is known about PEM's relation to other established measures of parent-child interactive behavior, such as maternal sensitivity and attachment. This is investigated in a sample of four months old infants and mothers with ( = 27) and without a diagnosis of postpartum depression ( = 44).

Parental Embodied Mentalizing (PEM) regards parents' nonverbal capacity to understand the infant's bodily manifested mental states and adjust his or her own movements accordingly. Little is known about how mothers suffering from postpartum depression (PPD) mentalize the infant on an embodied level. The aims of the present study were to investigate whether mothers meeting criteria for a PPD diagnosis differ from non-clinical mothers in regard to their PEM capacities and whether the severity of depressive symptoms was associated with PEM in mothers meeting criteria for a PPD diagnosis compared to non-clinical mothers.

This paper presents findings from an intensive, mixed methods case study of one session of psychoanalytic parent-infant psychotherapy (PPIP) addressing early relational trauma, and aims to shed light on the multimodal interactive processes that take place in the moment-to-moment exchanges comprising the therapeutic encounter. Different research methods were used on video material from PPIP sessions, including microanalysis of adult-infant interactions, discourse analysis of talk, and coding systems developed to study parent-infant interaction. These different perspectives were brought together with the clinical narrative to illuminate the complex, dynamic processes of parent-infant-therapist interaction.

Congenital posterolateral diaphragmatic hernia continues to be associated with a high mortality from ventilatory failure. To evaluate the malformation and factors associated with survival, 43 children with congenital diaphragmatic hernia seen in the neonatal period were studied; 20 survived. The male:female ratio was 2.
