Objective: Machine learning algorithms have shown groundbreaking results in neuroimaging. Herein, the authors evaluate the performance of a newly developed convolutional neural network (CNN) to detect and quantify the thickness, volume, and midline shift (MLS) of subdural hematoma (SDH) from noncontrast head CT (NCHCT).
Methods: NCHCT studies performed for the evaluation of head trauma in consecutive patients between July 2018 and April 2021 at a single institution were retrospectively identified.
Article Synopsis
- - Vitamin D is crucial for calcium and phosphate regulation, but its impact on fetal bone strength remains uncertain; this study examined the connection between maternal 25(OH)D levels and neonatal bone strength in 81 mother-infant pairs using quantitative ultrasound.
- - The research found that while maternal and cord blood 25(OH)D levels were strongly correlated, with cord blood levels being higher, there was no significant link between maternal vitamin D levels and neonatal bone strength or growth indicators.
- - Additionally, certain demographic factors influenced maternal vitamin D levels, with Jewish mothers having higher levels than Muslim mothers; however, bone strength (measured as speed of sound in tibial bones) remained similar across different maternal vitamin D status groups.
Article Synopsis
- * Using near-infrared spectroscopy, researchers measured regional oxygen saturation (rSOS) before and after each feeding method in 21 infants under 32 weeks gestation.
- * Results show that continuous feeding lowers rSOS compared to bolus feeding, but it does not significantly affect the oxygen extraction by the intestines; there was also a slight trend towards reduced systemic oxygen levels after bolus feeding.
Article Synopsis
- The study aimed to assess how blood transfusions affect iron status and other related parameters in stable preterm infants.
- Researchers analyzed data from 63 preterm infants before and within 24 hours after receiving red blood cell transfusions, measuring factors like hemoglobin, ferritin, hepcidin, and erythropoietin.
- Results showed an increase in hemoglobin and ferritin post-transfusion, while hepcidin levels also rose, indicating that preterm infants can regulate their iron levels influenced by their age.
Article Synopsis
- The study examined the impact of a twice daily exercise program on bone strength in very low birth weight (VLBW) preterm infants compared to once daily and no exercise interventions.
- Thirty-four VLBW infants were randomly placed into three groups for a four-week period, where they underwent assisted range-of-motion exercises starting shortly after birth.
- Results showed that while bone strength declined in all groups, those in the twice daily intervention experienced a significantly reduced decrease in bone strength, suggesting benefits for preventing osteopenia and fractures.
Article Synopsis
- The study explored how combining kangaroo care (KC) with maternal singing affects preterm infants and their mothers.
- It involved 86 stable preterm infants, measuring heart rate variability and maternal anxiety during different phases of KC, with and without singing.
- Findings showed that maternal singing during KC lowered maternal anxiety and improved heart rate variability in infants, though no changes were noted in infants' behavior or physiological parameters.
Background: The expression of CD64 (Fcgamma receptor) is increased in neutrophils from an almost negligible value to a marked level in patients with bacterial infections. CD64 expression on neutrophils might therefore be useful to differentiate between bacterial and viral infections in young children. We evaluated the usefulness of CD64 as a marker for the diagnosis of bacterial infections in children up to the age of 3 years and its ability to differentiate between bacterial and viral infections.

Objective: To evaluate the efficacy of two treatment regimens for eradication of H. pylori and the impact of bacterial susceptibility testing.
Inorganic fluorides were declared toxic under the Canadian Environmental Protection Act in 1993 based on their potential to cause long-term harmful effects in aquatic and terrestrial ecosystems, but information on the toxicity of sediment-associated fluoride to freshwater benthic organisms was considered incomplete. The purpose of this study was to determine the toxicity of aqueous and sediment-associated fluoride to several species of freshwater organisms and to determine if toxic effects could be expected under environmentally realistic exposures. Toxicity of fluoride (as NaF) in short-term (48-96-h) lethality tests was greatest for the amphipod Hyalella azteca (median lethal concentration [LC50] = 14.

Under observation there were 78 patients aged 41 to 70 years suffering from the glossalgia syndrome, as well as 25 clinically healthy subjects. An activation of the sympathoadrenal system was revealed in the patients. This was ascertained on the basis of the data on vanillylmandelic acid excretion with the urine.
