Lung ultrasound as a tool to guide respiratory physiotherapy

Lung ultrasound (LUS) is becoming an invaluable tool in the management of critically ill patients. We report two cases showing the importance of LUS as a guide to optimize respiratory physiotherapy in the intensive care unit, allowing a successful lung donation process and to redirect the physiotherapist's approach. The use of LUS requires an adequate training but it is becoming an important tool in management algorithms for critically ill patients.     

Sleep in mothers of children with epilepsy and its relation to their children's sleep

We conducted a cross-sectional study to examine sleep in mothers of children with epilepsy and its relation to their children's sleep. A total of 133 dyads of mothers and children with epilepsy aged 1.5–6 years were recruited between 2015 and 2018 from a children's hospital in northern Taiwan. Participating families provided demographic and health information, with children wearing an actigraphy monitor for 7 days and mothers completing sleep and depressive mood questionnaires. We found that 76 (57.1%) of the mothers had poor sleep quality, with 65 (48.9%) mothers having a clinically significant depressive symptom score. Mean actigraphic wake after sleep onset in children was 1.42 (standard deviation = 0.51) hours, with 126 (94.7%) of the children having a clinically significant sleep disturbance score. Multivariate regression analyses showed that higher depressive symptom scores in mothers (β = 0.14; p < .01) and higher sleep disturbance scores in children (β = 0.07; p = .04) were associated with poorer maternal sleep quality, even when maternal demographic characteristics and the child's clinical and epilepsy variables were considered. Findings from our study suggest that sleep disturbances are a shared problem for mothers and their children with epilepsy. Sleep in both mothers and their children with epilepsy should be evaluated in pediatric neurologic practices, with maternal depressive symptoms screened concurrently. Future pediatric epilepsy studies are warranted to examine whether a family-based intervention program would be effective to improve sleep in mother-child dyads and to promote better health and functioning of the entire family.     

Sulfated Progesterone Metabolites That Enhance Insulin Secretion via TRPM3 Are Reduced in Serum From Women With Gestational Diabetes Mellitus

Serum progesterone sulfates were evaluated in the etiology of gestational diabetes mellitus (GDM). Serum progesterone sulfates were measured using ultra-performance liquid chromatography–tandem mass spectrometry in four patient cohorts: 1) the Hyperglycemia and Adverse Pregnancy Outcomes study; 2) London-based women of mixed ancestry and 3) U.K.-based women of European ancestry with or without GDM; and 4) 11–13 weeks pregnant women with BMI ≤25 or BMI ≥35 kg/m² with subsequent uncomplicated pregnancies or GDM. Glucose-stimulated insulin secretion (GSIS) was evaluated in response to progesterone sulfates in mouse islets and human islets. Calcium fluorescence was measured in HEK293 cells expressing transient receptor potential cation channel subfamily M member 3 (TRPM3). Computer modeling using Molecular Operating Environment generated three-dimensional structures of TRPM3. Epiallopregnanolone sulfate (PM5S) concentrations were reduced in GDM (P < 0.05), in women with higher fasting plasma glucose (P < 0.010), and in early pregnancy samples from women who subsequently developed GDM with BMI ≥35 kg/m² (P < 0.05). In islets, 50 µmol/L PM5S increased GSIS by at least twofold (P < 0.001); isosakuranetin (TRPM3 inhibitor) abolished this effect. PM5S increased calcium influx in TRPM3-expressing HEK293 cells. Computer modeling and docking showed identical positioning of PM5S to the natural ligand in TRPM3. PM5S increases GSIS and is reduced in GDM serum. The activation of GSIS by PM5S is mediated by TRPM3 in both mouse and human islets.     

Effect of an equine-movement therapy program on gait, energy expenditure, and motor function in children with spastic cerebral palsy: a pilot study

The purpose of this study was to evaluate the effects of an 8-week program of hippotherapy on energy expenditure during walking; on the gait dimensions of stride length, velocity, and cadence; and on performance on the Gross Motor Function Measure (GMFM) in five children with spastic cerebral palsy (CP). A repeated-measures within-subjects design was used consisting of two baseline measurements taken 8 weeks apart, followed by an 8-week intervention period, then a posttest. After hippotherapy, all five children showed a significant decrease (X_r²;=7.6, P<0.05) in energy expenditure during walking and a significant increase (X_r²=7.6, P<0.05) in scores on Dimension E (Walking, Running, and Jumping) of the GMFM. A trend toward increased stride length and decreased cadence was observed. This study suggests that hippotherapy may improve energy expenditure during walking and gross motor function in children with CP.
