Respiratory muscle endurance training among patients with chronic diseases: A systematic review of available evidence.

This systematic review summarizes the available evidence on respiratory muscle endurance training involving voluntary isocapnic hyperpnoea among patients with chronic diseases. It includes both randomized and non-randomized controlled trials implementing this exercise training modality performed either alone or in combination with other interventions. It was conducted using the following databases: PubMed, Google Scholar, Physiotherapy Evidence Database (PEDro), Embase, CINAHL, CENTRAL, Cochrane and ReeDOC.

A common neural response to perceiving but not implicitly regulating infant and adult affect in postpartum mothers.

The transition to parenthood requires parents develop caregiving behaviors, such as the ability to identify their infant's emotions and regulate their own emotional response. Research has identified patterns of neural activation in parenting contexts that are interpreted as socioemotional processing. However, no prior research has directly tested whether mothers' neural responses to their infant's affect are the same as those involved in emotion perception/experience and regulation in other contexts.

Maternal interpretation of infant emotions related to mothers' mindfulness and mother-infant stress.

We aimed to identify maternal characteristics predicting interpretation of infant emotions, as well as relations between such interpretations and mother-infant stress. Specifically, we investigated (1) prospective associations between maternal dispositional mindfulness and interpretation of infant emotions, and (2) concurrent associations between maternal interpretation of infant emotions and mothers' and infants' cortisol during a dyadic stressor in a non-clinical community sample ( = 78) of mother-infant dyads. Mothers completed the Five Facet Mindfulness Questionnaire at 3 months postnatal, and the IFEEL Picture infant emotion interpretation task at 6 months postnatal.

Childhood maltreatment exposure is differentially associated with transdiagnostic perinatal depression symptoms.

Unlabelled: History of childhood maltreatment (CM) is common and robustly associated with prenatal and postpartum (perinatal) depression. Given perinatal depression symptom heterogeneity, a transdiagnostic approach to measurement could enhance understanding of patterns between CM and perinatal depression.

Methods: In two independently collected samples of women receiving care at perinatal psychiatry clinics (n = 523 and n = 134), we categorized longitudinal symptoms of perinatal depression, anxiety, stress, and sleep into transdiagnostic factors derived from the Research Domain Criteria and depression literatures.

Trimethylamine-N-oxide depletes urea in a peptide solvation shell.

Trimethylamine-N-oxide (TMAO) and urea are metabolites that are used by some marine animals to maintain their cell volume in a saline environment. Urea is a well-known denaturant, and TMAO is a protective osmolyte that counteracts urea-induced protein denaturation. TMAO also has a general protein-protective effect, for example, it counters pressure-induced protein denaturation in deep-sea fish.
