Acceptability of Telelactation Services for Breastfeeding Support Among Black Parents: Semistructured Interview Study.

BACKGROUND: While breastfeeding rates have increased in the United States in recent years, racial and ethnic disparities persist. Telelactation may help reduce disparities by increasing access to lactation consultants, but there is limited research on acceptability among minoritized individuals. OBJECTIVE: We aimed to explore experiences with telelactation among Black parents and identify strategies to make services more culturally appropriate. METHODS: We selected 20 Black parents who were given access to telelactation services from an ongoing National Institutes of Health-funded randomized controlled trial (the Tele-MILC trial) to participate in semistructured interviews. Interviews addressed birth experiences, use and opinions about telelactation, comparison of telelactation to in-person lactation support, and recommendations to improve telelactation services. The thematic analysis was informed by a previously reported theoretical framework of acceptability and RAND Corporation's equity-centered model. RESULTS: Users appreciated the convenience of telelactation and reported that lactation consultants were knowledgeable and helpful. Participants wanted more options to engage with lactation consultants outside of video visits (eg, SMS text messaging and asynchronous resources). Users who had a lactation consultant of color mentioned that racial concordance improved the experience; however, few felt that racial concordance was needed for high-quality telelactation support. CONCLUSIONS: While Black parents in our sample found telelactation services to be acceptable, telelactation could not, in isolation, address the myriad barriers to long-duration breastfeeding. Several changes could be made to telelactation services to increase their use by minoritized populations.

Suprachiasmatic nucleus promotes hyperglycemia induced by sleep delay.

Short sleep is linked to disturbances in glucose metabolism and may induce a prediabetic condition. The biological clock in the suprachiasmatic nucleus (SCN) regulates the glucose rhythm in the circulation and the sleep-wake cycle. SCN vasopressin neurons (SCNVP) control daily glycemia by regulating the entrance of glucose into the arcuate nucleus (ARC). Thus, we hypothesized that sleep delay may influence SCN neuronal activity. We, therefore, investigated the role of SCNVP when sleep is disrupted by forced locomotor activity. After 2 h of sleep delay, rats exhibited decreased SCNVP neuronal activity, a decrease in the glucose transporter GLUT1 expression in tanycytes lining the third ventricle, lowered glucose entrance into the ARC, and developed hyperglycemia. The association between reduced SCNVP neuronal activity and hyperglycemia in sleep-delayed rats was evidenced by injecting intracerebroventricular vasopressin; this increased GLUT1 immunoreactivity in tanycytes, thus promoting normoglycemia. Following sleep recovery, glucose levels decreased, whereas SCNVP neuronal activity increased. These results imply that sleep-delay-induced changes in SCNVP activity lead to glycemic impairment, inferring that disruption of biological clock function might represent a critical step in developing type 2 diabetes.

Clinician and Staff Perspectives on Implementing Adverse Childhood Experience (ACE) Screening in Los Angeles County Pediatric Clinics.

PURPOSE: To understand clinician and clinical staff perspectives on the implementation of routine Adverse Childhood Experience (ACE) screening in pediatric primary care. METHODS: We conducted a qualitative evaluation in 5 clinics in Los Angeles County, California, using 2 rounds of focus group discussions: during an early phase of the initiative, and 7 months later. In the first round, we conducted 14 focus group discussions with 67 participants. In the second round, we conducted 12 focus group discussions with 58 participants. Participants comprised clinic staff involved in ACE screening, including frontline staff that administer the screening, medical clinicians that use screening to counsel patients and make referrals, and psychosocial support staff who may receive referrals. RESULTS: Themes were grouped into 3 categories: (1) screening acceptability and perceived utility, (2) implementation and quality improvement, and (3) effects of screening on patients and clinicians. Regarding screening acceptability and perceived utility, clinicians generally considered ACE screening to be acceptable and useful. In terms of implementation and quality improvement, significant barriers included: insufficient time for screening and response, insufficient training, and lack of clarity about referral networks and resources that could be offered to patients. Lastly, regarding effects of screening, clinicians expressed that ACE screening helped elicit important patient information and build trust with patients. Further, no adverse events were reported from screening. CONCLUSIONS: Clinic staff felt ACE screening was feasible, acceptable, and beneficial within pediatric care settings to improve trauma-informed care and that ACE screening could be strengthened by addressing time constraints and limited referral resources.

Patient and Caregiver Perspectives on Implementation of ACE Screening in Pediatric Care Settings: A Qualitative Evaluation.

INTRODUCTION: This qualitative research study explored the perspectives of adolescents, 12 to 19-years-old, and caregivers of children under 12-years-old on the acceptibility of adverse childhood experiences (ACEs) screenings in five pediatric clinics. METHOD: A constructivist grounded theory approach was utilized. One-on-one semistructured phone interviews were conducted with 44 adolescents and 95 caregivers of children less than 12 years old. Interviews were analyzed using thematic analysis. RESULTS: Most participants reported feeling comfortable discussing ACEs with their providers. Some reported that screening helped build trust. Others expressed privacy concerns and did not receive information about the reason for screening. Adolescent patients shared conflicting feelings-of both comfort and discomfort. Caregivers attending to multiple children, foster parents, and monolingual Spanish speakers disclosed unique challenges to ACEs screening. We found no evidence of lasting adverse effects. DISCUSSION: Participants generally found ACEs screenings acceptable. Some adolescents identified benefits from the experience. However, clinics planning to adopt routine ACEs screening should ensure clear messaging on why screening is occurring, anticipate and address privacy concerns, and adopt workflows to discuss screening results.

The "Birth-Centered Outcomes Research Engagement (B-CORE) in Medi-Cal" Project: Community-Generated Recommendations to Decrease Maternal Mortality and Severe Maternal Morbidity.

BACKGROUND: Through applied research and health care quality improvement, California has achieved a maternal mortality (MM) rate significantly lower than that measured nationally. However, Medicaid (Medi-Cal)-insured births in the state continue to experience disproportionate shares of MM and severe maternal morbidity (SMM), which often precedes death. Failure to engage the Medi-Cal community in this work may impede efforts to increase equity. METHODS: This community engagement project used deliberative democracy methods to engage stakeholders with lived experience in California's Medi-Cal perinatal care system to generate an actionable and specific agenda of recommendations to decrease MM and SMM in the Medi-Cal population. FINDINGS: A total of 37 Medi-Cal stakeholders-representing birthing people, providers, health plan administrators, and advocates-participated in longitudinal co-learning sessions on the topics of MM/SMM in Medi-Cal. Most of these stakeholders (75.7%) then participated in deliberation sessions. Deliberation recommendations fell into five distinct categories: Medi-Cal perinatal covered benefits, data collection and dissemination, patient experience and its link to care quality, Medi-Cal reimbursement rates, and accountability with respect to racism in perinatal care. Stakeholders identified the Medi-Cal system actors best positioned to implement specific recommendations to directly impact MM/SMM. CONCLUSIONS: This project demonstrates the feasibility and success of using deliberative democracy methods to generate local and community-generated solutions to critical problems in health equity. Active and engaged stakeholders were keen to identify both immediate actions and long-term research and quality improvement paradigm shifts to support birth equity in Medi-Cal.

The Active Role of Pericytes During Neuroinflammation in the Adult Brain.

Microvessels in the central nervous system (CNS) have one of the highest populations of pericytes, indicating their crucial role in maintaining homeostasis. Pericytes are heterogeneous cells located around brain microvessels; they present three different morphologies along the CNS vascular tree: ensheathing, mesh, and thin-strand pericytes. At the arteriole-capillary transition ensheathing pericytes are found, while mesh and thin-strand pericytes are located at capillary beds. Brain pericytes are essential for the establishment and maintenance of the blood-brain barrier, which restricts the passage of soluble and potentially toxic molecules from the circulatory system to the brain parenchyma. Pericytes play a key role in regulating local inflammation at the CNS. Pericytes can respond differentially, depending on the degree of inflammation, by secreting a set of neurotrophic factors to promote cell survival and regeneration, or by potentiating inflammation through the release of inflammatory mediators (e.g., cytokines and chemokines), and the overexpression of cell adhesion molecules. Under inflammatory conditions, pericytes may regulate immune cell trafficking to the CNS and play a role in perpetuating local inflammation. In this review, we describe pericyte responses during acute and chronic neuroinflammation.

Minor Changes in Daily Rhythms Induced by a Skeleton Photoperiod Are Associated with Increased Adiposity and Glucose Intolerance.

Eating during the rest phase is associated with metabolic syndrome, proposed to result from a conflict between food consumption and the energy-saving state imposed by the circadian system. However, in nocturnal rodents, eating during the rest phase (day-feeding, DF) also implies food intake during light exposure. To investigate whether light exposure contributes to DF-induced metabolic impairments, animals receive food during the subjective day without light. A skeleton photoperiod (SP) is used to entrain rats to a 12:12 cycle with two short light pulses framing the subjective day. DF-induced adiposity is prevented by SP, suggesting that the conflict between light and feeding stimulates fat accumulation. However, all animals under SP conditions develop glucose intolerance regardless of their feeding schedule. Moreover, animals under SP with ad libitum or night-feeding have increased adiposity. SP animals show a delayed onset of the daily rise in body temperature and energy expenditure and shorter duration of nighttime activity, which may contribute to the metabolic disturbances. These data emphasize that metabolic homeostasis can only be achieved when all daily cycling variables are synchronized. Even small shifts in the alignment of different metabolic rhythms, such as those induced by SP, may predispose individuals to metabolic disease.

Circadian modulation of microglial physiological processes and immune responses.

Microglia is considered the central nervous system (CNS) resident macrophages that establish an innate immune response against pathogens and toxins. However, the recent studies have shown that microglial gene and protein expression follows a circadian pattern; several immune activation markers and clock genes are expressed rhythmically without the need for an immune stimulus. Furthermore, microglia responds to an immune challenge with different magnitudes depending on the time of the day. This review examines the circadian control of microglia function and the possible physiological implications. For example, we discuss that synaptic prune is performed in the cortex at a certain moment of the day. We also consider the implications of daily microglial function for maintaining biological rhythms like general activity, body temperature, and food intake. We conclude that the developmental stage, brain region, and pathological state are not the only factors to consider for the evaluation of microglial functions; instead, emerging evidence indicates that circadian time as an essential aspect for a better understanding of the role of microglia in CNS physiology.

Use of and Attitudes About Telelactation Services among New Parents.

Background: We conducted a national, cross-sectional survey among new parents to explore use and acceptability of telelactation. Methods: Recruitment occurred between October 2021 and January 2022 on Ovia's parenting mobile phone application. Poststratification survey weights were used, and logistic and linear regression models estimated associations between demographics and telelactation use. Results: Among 1,617 respondents, 33.8% had at least one telelactation visit. Odds of any telelactation visit(s) were greater for parents who gave birth in 2021 versus 2019 (odds ratio [OR]: 1.69, 95% confidence interval [CI]: 1.26-2.25), insured by Medicaid (OR: 1.43, 95% CI: 1.02-2.02), and younger parents (OR: 2.07, 95% CI: 1.32-3.34). In total, 56.0% agreed that they would be comfortable breastfeeding over video to get help, and 27.6% agreed that lactation support over video is as good as in-person support. Conclusions: Telelactation is increasingly common and acceptable to many parents.

Changes in Breastfeeding and Lactation Support Experiences During COVID.

Background: We surveyed parents who gave birth from 2019 to 2021 to examine changes in breastfeeding experiences and professional and lay breastfeeding support services due to the coronavirus disease 2019 (COVID-19) pandemic. We also examined racial and ethnic disparities in breastfeeding support. Materials and Methods: A cross-sectional opt-in survey of 1,617 parents was administered on Ovia's parenting app in January 2022. Respondents were 18-45 years of age and delivered in one of three birth cohorts: August-December 2019, March-May 2020, or June-August 2021. We fit linear and logistic regression models wherein the outcomes were six breastfeeding support and experience measures, adjusting for birth cohort and respondent demographics. Results: Parents who gave birth in the early pandemic versus those in the prepandemic had reduced odds of interacting with lactation consultants (odds ratio [OR]: 0.63; 95% confidence interval [CI]: 0.44-0.90), attending breastfeeding classes (OR: 0.71; 95% CI: 0.54-0.94), meeting breastfeeding goals (OR: 0.65; 95% CI: 0.46-0.92), and reporting it was easy to get breastfeeding help (estimate: -0.36; 95% CI: -0.55 to -0.17). Birth cohort was not associated with use of donor milk or receipt of in-hospital help. The later pandemic cohort differed from the prepandemic cohort for one outcome: they were less likely to meet their breastfeeding goals (OR: 0.67; 95% CI: 0.48-0.95). There were racial and ethnic disparities in the use of multiple types of breastfeeding support. Although one-third of respondents felt that the pandemic facilitated breastfeeding because of more time at home, 18% felt the pandemic posed additional challenges including disruptions to lactation support. Conclusions: Parents who gave birth in the later pandemic did not report significant disruptions to professional breastfeeding support, likely as a result of the growth of virtual services. However, disparities in receipt of support require policy attention and action.

Birth-Centered Outcomes Research Engagement (B-CORE) in Medi-Cal: Community-Generated Recommendations to Decrease Maternal Mortality and Severe Maternal Morbidity.

California leads the nation with its relatively low rate of maternal deaths during pregnancy and the postpartum period. However, individuals insured via Medi-Cal suffer a disproportionate share of maternal deaths and severe complications at birth; within this group of publicly insured individuals, certain racial and/or ethnic groups have even higher rates of poor outcomes. The state can attribute part of its success in lowering rates of maternal mortality (MM) to the implementation of a data-driven statewide portfolio of quality improvement activities focused on the leading causes of maternal death. This quality improvement infrastructure has not previously been leveraged to respond in a focused way to the relatively large shares of MM and morbidity still seen in the Medi-Cal-insured population. B-CORE aimed to expand on existing statewide quality improvement efforts to effectively mitigate these adverse outcomes in Medi-Cal births by engaging Medi-Cal stakeholders.

Hormones, psychotic disorders, and cognition in perinatal women: a mini review.

Previous scientific evidence has shown a relationship between hormones and the onset and relapse of perinatal psychotic disorders (PPD) in women during pregnancy, childbirth, and the postpartum period. In healthy women the interaction between hormones and cognitive changes has been confirmed mainly in memory, attention, and executive function during pregnancy and postpartum, which respond to adaptive demands related to parenting tasks. In women with psychotic episodes there is a significant impairment in several cognitive functions, but studies of the perinatal period are limited. The objective of this mini review is to analyze the main findings to identify whether hormonal changes interact with the onset of PPD and cognitive impairment in perinatal women. The studies included samples of women with psychosis, risk of developing psychosis, bipolar psychosis, schizoaffective psychosis, and psychotic symptoms, during pregnancy and postpartum. Findings contributed to knowledge about five hypotheses regarding the relationship between hormones in the perinatal period and the appearance of PPD. Nevertheless, this review did not find reports of evidence of a relationship between hormonal production and cognitive function among women with clinically diagnosed PPD, suggesting a research gap. Clinical implications of assessing hormonal production and cognitive function in PPD are discussed. Although the evidence identified is scarce and heterogeneous, the findings call for further research with clinical samples on the role of hormones in perinatal psychotic disorders, especially as they relate to the study of cognition. This will promote more consistent evidence and understanding of PPD etiopathology that can guide early and effective multidisciplinary interventions.

Cross-reactive neutralizing human monoclonal antibodies mapping to variable antigenic sites on the norovirus major capsid protein.

Human noroviruses are the major viral cause of acute gastroenteritis around the world. Although norovirus symptoms are in most cases mild and self-limited, severe and prolonged symptoms can occur in the elderly and in immunocompromised individuals. Thus, there is a great need for the development of specific therapeutics that can help mitigate infection. In this study, we sought to characterize a panel of human monoclonal antibodies (mAbs; NORO-123, -115, -273A, -263, -315B, and -250B) that showed carbohydrate blocking activity against the current pandemic variant, GII.4 Sydney 2012. All antibodies tested showed potent neutralization against GII.4 Sydney virus in human intestinal enteroid culture. While all mAbs recognized only GII.4 viruses, they exhibited differential binding patterns against a panel of virus-like particles (VLPs) representing major and minor GII.4 variants spanning twenty-five years. Using mutant VLPs, we mapped five of the mAbs to variable antigenic sites A (NORO-123, -263, -315B, and -250B) or C (NORO-115) on the major capsid protein. Those mapping to the antigenic site A showed blocking activity against multiple variants dating back to 1987, with one mAb (NORO-123) showing reactivity to all variants tested. NORO-115, which maps to antigenic site C, showed reactivity against multiple variants due to the low susceptibility for mutations presented by naturally-occurring variants at the proposed binding site. Notably, we show that cross-blocking and neutralizing antibodies can be elicited against variable antigenic sites. These data provide new insights into norovirus immunity and suggest potential for the development of cross-protective vaccines and therapeutics.

A Process Evaluation of Primary Care Behavioral Health Integration in the Military Health System.

Behavioral health (BH) problems are common in the military and can adversely affect force readiness. Research suggests that primary care-behavioral health (PCBH) integration can improve BH outcomes by making high-quality BH care available in more accessible settings. However, sustaining high-quality implementation of PCBH is challenging. The authors conducted a process evaluation of the PCBH program in the military health system to understand why the program is working as it is and provide recommendations for quality improvement. They conducted semistructured interviews, rigorously coded the qualitative data to identify causal links, and created and validated causal loop diagrams that provide a visualization of how the system is working. Findings fall into four key areas: staffing and capabilities, valued tasks, program stewardship, and fostering program awareness and support. Overall, the authors found that the PCBH program is highly valued by primary care staff. However, the PCBH care model is inconsistently adhered to, owing to a combination of staff preferences, local pressures, and lack of knowledge of PCBH staff roles. Recommendations are offered to improve program implementation.

Independent Evaluation of the New York State 1115 Waiver Amendment: The Children's Design: Interim Findings.

In an effort to streamline care for children and youth under age 21 with needs for home- and community-based services (HCBS), New York State consolidated several prior 1915(c) waivers into a single Children's Waiver and amended their Section 1115 Medicaid Redesign Team waiver. The 1115 waiver amendment allows the state to move services covered by the consolidated Children's Waiver from fee for service to Medicaid managed care (MMC) and to target eligibility to medically needy family-of-one children who meet clinical criteria and are enrolled in the consolidated Children's Waiver but do not qualify for Medicaid due to family income. Together, these waiver amendments are called the "Children's Design," which was implemented in 2019. In this interim evaluation, the authors identify facilitators of, and barriers to, implementation of the Children's Design and describe baseline trends in outcomes of interest to its future evaluation. The authors found that: (1) providers, advocates, MMC plan representatives, and government partners perceived the transition to the Children's Design as challenging and were particularly concerned about the burden of accessing care on children's families and reductions in service availability; (2) prior to the Children's Design implementation, parents of children with chronic conditions had high levels of satisfaction with their primary care providers but were less satisfied with their ability to access special equipment and therapies and with coordination efforts among multiple providers; and (3) at baseline, the levels of quality indicators for children did not change significantly, with the exception of some primary care indicators for young children, which improved.

Suprachiasmatic nucleus-mediated glucose entry into the arcuate nucleus determines the daily rhythm in blood glycemia.

Glycemia is maintained within very narrow boundaries with less than 5% variation at a given time of the day. However, over the circadian cycle, glycemia changes with almost 50% difference. How the suprachiasmatic nucleus, the biological clock, maintains these day-night variations with such tiny disparities remains obscure. We show that via vasopressin release at the beginning of the sleep phase, the suprachiasmatic nucleus increases the glucose transporter GLUT1 in tanycytes. Hereby GLUT1 promotes glucose entrance into the arcuate nucleus, thereby lowering peripheral glycemia. Conversely, blocking vasopressin activity or the GLUT1 transporter at the daily trough of glycemia increases circulating glucose levels usually seen at the peak of the rhythm. Thus, biological clock-controlled mechanisms promoting glucose entry into the arcuate nucleus explain why peripheral blood glucose is low before sleep onset.

Protection against SARS-CoV-2 Beta variant in mRNA-1273 vaccine-boosted nonhuman primates.

Neutralizing antibody responses gradually wane against several variants of concern (VOCs) after vaccination with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine messenger RNA-1273 (mRNA-1273). We evaluated the immune responses in nonhuman primates that received a primary vaccination series of mRNA-1273 and were boosted about 6 months later with either homologous mRNA-1273 or heterologous mRNA-1273.ß, which encompasses the spike sequence of the B.1.351 Beta variant. After boost, animals had increased neutralizing antibody responses across all VOCs, which was sustained for at least 8 weeks after boost. Nine weeks after boost, animals were challenged with the SARS-CoV-2 Beta variant. Viral replication was low to undetectable in bronchoalveolar lavage and significantly reduced in nasal swabs in all boosted animals, suggesting that booster vaccinations may be required to sustain immunity and protection.
