Development and Application of Novel Caregiver Hygiene Behavior Measures Relating to Food Preparation, Handwashing, and Play Environments in Rural Kenya
Exposure to fecal pathogens results in both acute and chronic sequalae in young children. Diarrhea causes nearly 20% of all under-five mortality, while even sub-clinical enteric infections may lead to growth shortfalls. Stunting affects nearly 165 million children globally and results in lifelong and intergenerational effects for the world’s poorest populations. Caregiver hygiene behaviors, such as those surrounding handwashing and food preparation, play a critical role in exposure to fecal pathogens; standard metrics to assess these behaviors are warranted to provide a means of quantifying the impact these behaviors have on enteric infections and to evaluate the success or failure of interventions and programs. This paper documents the development of three novel caregiver hygiene behavior measures: hygienic food preparation and storage, handwashing at key times, and provision of a safe play environment for children under two years. We developed these measures using formative qualitative work, survey creation and deployment theoretically underpinned by the COM-B model of behavior change, and exploratory and confirmatory factor analysis. The final measure for hygienic food preparation and storage includes 10 items across two factors; the final measure for handwashing at key times includes 15 items across three factors; and the final measure for safe play environment contains 13 items across three factors. Future researchers may employ these measures to assess caregiver behaviors in other populations, identify specific behavioral dimensions that should be the focus of interventions, and evaluate interventions and programs
Gestational stress decreases postpartum mitochondrial respiration in the prefrontal cortex of female rats
Postpartum depression (PPD) is a major psychiatric complication of childbirth, affecting up to 20% of mothers, yet remains understudied. Mitochondria, dynamic organelles crucial for cell homeostasis and energy production, share links with many of the proposed mechanisms underlying PPD pathology. Brain mitochondrial function is affected by stress, a major risk factor for development of PPD, and is linked to anxiety-like and social behaviors. Considering the importance of mitochondria in regulating brain function and behavior, we hypothesized that mitochondrial dysfunction is associated with behavioral alterations in a chronic stress-induced rat model of PPD. Using a validated and translationally relevant chronic mild unpredictable stress paradigm during late gestation, we induced PPD-relevant behaviors in adult postpartum Wistar rats. In the mid-postpartum, we measured mitochondrial function in the prefrontal cortex (PFC) and nucleus accumbens (NAc) using high-resolution respirometry. We then measured protein expression of mitochondrial complex proteins and 4-hydroxynonenal (a marker of oxidative stress), and Th1/Th2 cytokine levels in PFC and plasma. We report novel findings that gestational stress decreased mitochondrial function in the PFC, but not the NAc of postpartum dams. However, in groups controlling for the effects of either stress or parity alone, no differences in mitochondrial respiration measured in either brain regions were observed compared to nulliparous controls. This decrease in PFC mitochondrial function in stressed dams was accompanied by negative behavioral consequences in the postpartum, complex-I specific deficits in protein expression, and increased Tumor Necrosis Factor alpha cytokine levels in plasma and PFC. Overall, we report an association between PFC mitochondrial respiration, PPD-relevant behaviors, and inflammation following gestational stress, highlighting a potential role for mitochondrial function in postpartum health

High rate of persistent symptoms up to 4 months after community and hospital-managed SARS-CoV-2 infection
Recovery after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection remains uncertain. A considerable proportion of patients experience persistent symptoms after SARS-CoV-2 infection which impacts health-related quality of life and physical function
