    Abstract Purpose of review: The COVID-19 pandemic and protracted home confinement required adjustments to schedules and routines generating concern about children's sleep. This review describes general considerations regarding children's sleep, changes and disturbances in their sleep during the pandemic, and the association of sleep measures with health and psychological outcomes in general and in the context of the pandemic.
    Recent findings: A number of studies found an increase in the duration of children's sleep with later bedtimes and waketimes for some children. The research also documented sleep disturbances and associations between children's sleep and psychological outcomes. The extent to which increased sleep duration and changed sleep behaviors translated into improved sleep quality and/or a change in sleep disturbances remains unclear. This review suggests the importance of considering children's sleep in other mass trauma situations including, for example, natural and man-made disasters, as well as pandemics.

    Abstract Purpose of review: This paper examines children's physical activity and sedentary behavior and associated psychological outcomes coincident with the COVID-19 pandemic.
    Recent findings: Generally, the research has found decreased physical activity and increased sedentary behavior, both of which are associated with various psychological outcomes. The research on sedentary behavior has focused on screen time with minimal consideration of other sedentary behaviors or of specific physical activities or the context in which these behaviors occurred. Changes in children's daily routines and activities have received little attention in the mass trauma research despite the fact that disasters disrupt individual, family, and community life. Thus, the current report contributes to an understanding of the breadth of mass trauma effects, underscores the importance of physical activity and sedentary behavior and their associations with health and psychological outcomes, and is a reminder to consider children's daily lives both during times of crisis and under usual circumstances.

    Abstract The psychological strain of many psychiatric disorders arises from difficulties encountered in social interactions. Social withdrawal is often the first symptom of neuropsychiatric disorders. The authors explore the various options for training social cognition skills. Social cognition was assessed using the Movie for the Assessment of Social Cognition (MASC). After completion of mentalization-based therapy (MBT) training, MASC scores improved significantly in health care providers (p = .006, r = .57). Mentalizing (operationalized with reflective functioning [RF]) was assessed in the MBT group (Group A) and compared with RF in a control group (Group B). RF was significantly higher in Group A (RF = 4.35, SD = 1.19) than in Group B (RF = 3.43, SD = 1.70) (p = .0385; Cohen's d = 0.65). MBT might be a promising intervention in social cognition training. Mentalizing skills might be associated with attitude.

    Abstract Purpose of review: This paper reports a review of the empirical research examining the association between mass trauma media contact and depression in children, the factors that may influence the association, and the difficulties encountered in the study of media effects on depression.
    Recent findings: All of the included studies assessed general population samples. Pre-COVID-19 research focused primarily on television coverage alone or on multiple media forms including television, while COVID-19 media studies examined various media forms including social media. Most studies used cross-sectional design and non-probability sampling. The review revealed inconclusive findings across studies. The study of mass trauma media effects on depression in children is complicated by a number of potential confounding factors and by the relatively high prevalence of depression in the general population. Media contact was a relatively minor consideration among other interests in the extant studies which failed to explore numerous issues that warrant attention in future research.

    Abstract Ci-VSP, a recently described protein with sequence similarity to both the voltage-sensing domain of a voltage-gated potassium channel and the phosphatase PTEN, functions as a transmembrane phosphoinositide phosphatase that is regulated by changes in voltage across the plasma membrane. Ci-VSP dephosphorylated phosphatidylinositol-3,4,5-trisphosphate [PtdIns(3,4,5)P3] in vitro, exhibited capacitative currents that resembled ion channel gating currents, and, when coexpressed with potassium channels that are regulated by PtdIns(4,5)P2, conferred sensitivity of potassium current amplitude to prolonged changes in membrane potential. How the voltage-sensing (VS) domain of Ci-VSP communicates with the phosphatase domain, and how the VS domain moves its charges across the membrane electric field in the absence of a transmembrane pore domain, remain to be determined.
