Article Synopsis
  • A study looked at how the length of telomeres (the ends of chromosomes) in pregnant moms changes during their pregnancies and how it relates to stress.
  • Researchers examined blood samples from first-time moms and compared results at three points during pregnancy and after giving birth.
  • They found that telomere length did not change much during pregnancy, but moms who had cesarean deliveries had shorter telomeres after giving birth compared to those who had vaginal births.

Objective: Advancing understanding of how early adversity arises, manifests, and contributes to health difficulties depends on accurate measurement of children's experiences. In early life, exposure to adversity is often intertwined with that of one's caregivers. We present preliminary psychometric properties of a novel measure of adversity, the Assessment of Parent and Child Adversity (APCA), which simultaneously characterizes parents' and children's adversity.

J Allergy Clin Immunol

June 2022

Mast Cell Biology Section, Laboratory of Allergic Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, Md.

Mast cell (MC) activation is a key event in allergic reactions, other inflammatory states, and MC activation syndromes. MC-stabilizing agents, mediator-targeting drugs, and drugs interfering with mediator effects are often prescribed for these patients. However, the clinical efficacy of these drugs varies depending on the numbers of involved MCs and the underlying pathology.

Stress and Its Consequences-Biological Strain.

Am J Perinatol

July 2024

Division of Neonatal and Developmental Medicine, Department of Pediatrics, Stanford University School of Medicine, Stanford, California.

Understanding the role of stress in pregnancy and its consequences is important, particularly given documented associations between maternal stress and preterm birth and other pathological outcomes. Physical and psychological stressors can elicit the same biological responses, known as biological strain. Chronic stressors, like poverty and racism (race-based discriminatory treatment), may create a legacy or trajectory of biological strain that no amount of coping can relieve in the absence of larger-scale socio-behavioral or societal changes.

An alarming high proportion of youth experience at least one kind of stressor in childhood and/or adolescence. Exposure to early life stress is associated with increased risk for psychopathology, accelerated biological aging, and poor physical health; however, it is important to recognize that not all youth who experience such stress go on to develop difficulties. In fact, resilience, or positive adaptation in the face of adversity, is relatively common.

Exposure to ozone is a well-documented risk factor for negative physical health outcomes but has been considered less frequently in the context of socioemotional health. We examined whether levels of neighborhood ozone predicted trajectories of depressive symptoms over a four-year period in 213 adolescents (ages 9-13 years at baseline; 57% female; 53% of minority race/ethnicity). Participants self-reported depressive and other types of psychopathology symptoms up to 3 times, and their home addresses were used to compute ozone levels in their census tract.

Intrinsic Connectivity and Family Dynamics: Striatolimbic Markers of Risk and Resilience in Youth at Familial Risk for Mood Disorders.

Biol Psychiatry Cogn Neurosci Neuroimaging

September 2022

Department of Psychiatry and Behavioral Sciences, Stanford University, Stanford, California. Electronic address:

Background: Few studies to date have characterized functional connectivity (FC) within emotion and reward networks in relation to family dynamics in youth at high familial risk for bipolar disorder (HR-BD) and major depressive disorder (HR-MDD) relative to low-risk youth (LR). Such characterization may advance our understanding of the neural underpinnings of mood disorders and lead to more effective interventions.

Methods: A total of 139 youth (43 HR-BD, 46 HR-MDD, and 50 LR) aged 12.

Polycythemia vera (PV) is a Philadelphia chromosome-negative myeloproliferative neoplasm driven by the JAK2 V617F (or rarely exon 12) mutation. Its natural history can extend over a few decades, and therefore treatment planning is predicated on continual reassessment of traditional risk features (age, prior thrombosis) to evaluate the need for cytoreduction besides foundational therapy with low-dose aspirin and stringent phlebotomy. Shorter- and longer-term patient goals should be considered in light of several variables such as comorbid conditions (especially cardiovascular risk factors), disease symptoms, and the risk-benefit profile of available drugs.

Objectives: Sphenomaxillary plate (SMP) is an inconstant bony septum separating the maxillary and sphenoid sinuses. Neglecting the SMP during endoscopic sinus surgery may lead to mistaking the sphenoid sinus for the posterior ethmoid cell with potentially dangerous consequences. However, its proper identification may allow planned sphenoidotomy through the posterior wall of the maxillary sinus or to enlarge transnasal or transethmoidal sphenoidotomy.

Different dimensions of adversity may affect mental health through distinct neurobiological mechanisms, though current supporting evidence consists largely of cross-sectional associations between threat or deprivation and fronto-limbic circuitry. In this exploratory three-wave longitudinal study spanning ages 9-19 years, we examined the associations between experiences of unpredictability, threat, and deprivation with the development of functional connectivity within and between three brain networks implicated in psychopathology: the salience (SAL), default mode (DMN), and fronto-parietal (FPN) networks, and tested whether network trajectories moderated associations between adversity and changes in internalizing symptoms. Connectivity decreased with age on average; these changes differed by dimension of adversity.

Liver transplantation (LTx) is the best treatment for patients with early-stage hepatocellular carcinoma (HCC). The Milan criteria positively influenced results of liver transplantation and were adopted by the majority of cancer centers, becoming the criterion standard treatment for early-stage HCC. Despite the use of restrictive criteria, recurrence is still high, affecting between 8% and 20% of cases, and is a significant predictor of survival after LTx.

The impact of COVID-19-related stress on perinatal women is of heightened public health concern given the established intergenerational impact of maternal stress-exposure on infants and fetuses. There is urgent need to characterize the coping styles associated with adverse psychosocial outcomes in perinatal women during the COVID-19 pandemic to help mitigate the potential for lasting sequelae on both mothers and infants. This study uses a data-driven approach to identify the patterns of behavioral coping strategies that associate with maternal psychosocial distress during the COVID-19 pandemic in a large multicenter sample of pregnant women (N = 2876) and postpartum women (N = 1536).

Updated Diagnostic Criteria and Classification of Mast Cell Disorders: A Consensus Proposal.

Hemasphere

November 2021

Mast Cell Biology Section, Laboratory of Allergic Diseases, NIAID, NIH, Bethesda, Maryland, USA.

Mastocytosis is a hematologic neoplasm characterized by expansion and focal accumulation of neoplastic mast cells (MC) in diverse organs, including the skin, bone marrow (BM), spleen, liver, and gastrointestinal tract. The World Health Organization classification divides the disease into prognostically distinct variants of cutaneous mastocytosis (CM) and systemic mastocytosis (SM). Although this classification remains valid, recent developments in the field and the advent of new diagnostic and prognostic parameters created a need to update and refine definitions and diagnostic criteria in MC neoplasms.
