Comparative Study
Oxygen saturation/minute heart rate index: Simple lung function test for children.
The severity of airway obstruction can be accurately determined on spirometry in children with asthma. Other assessments may include peak expiratory flow and pulse oximetry. In the present study, we evaluated the validity and reliability of oxygen saturation/minute heart rate (SpO2 /MHR) index in the prediction of degree of severe airway obstruction in children with asthma. ⋯ SpO2 /MHR ratio appears to be a highly useful index to assess airway obstruction in older children with asthma. Thus, it can be used as a marker of airway obstruction severity when spirometry is not available.

Rectal temperature is commonly used as the core temperature during therapeutic hypothermia therapy in neonates with hypoxic-ischemic encephalopathy (HIE). The purpose of this study was to examine whether nasopharyngeal temperature could serve as a substitute for rectal temperature. ⋯ Nasopharyngeal temperature in neonates with perinatal HIE undergoing therapeutic hypothermia may be a suitable substitute for rectal temperature.

The aim of this study was to evaluate clinical presentation, diagnostic studies, and volvulus rate and to describe the unusual clinical clues of intestinal malrotation. ⋯ Malrotation with or without midgut volvulus is not a rare condition and should be kept in mind for any age group. Specific signs of diagnosis are not easily identified. In the case of unusual clinical presentation, diagnosis may be delayed and can result in catastrophic consequences if intestinal perfusion occurs. Although midgut volvulus is seen most frequently in infants, risk and complication rate are high beyond 1 year of age as well, and can manifest as failure to thrive, food intolerance, and abdominal pain needing recurrent hospitalization. Diagnostic suspicion and interdisciplinary coordination are essential for timely diagnosis and surgical treatment.

Observational Study
Arterial oxygen saturation and heart rate after birth in newborns with and without maternal bonding.
The aim of this study was to determine and compare changes in arterial oxygen saturation (SpO2 ) and heart rate (HR) in healthy term infants with and without maternal bonding. ⋯ In healthy term newborns, maternal bonding in infants born by cesarean section did not have effects on SpO2 . Some differences were observed in HR between infants born by cesarean section with and without bonding.

Although both self-paced and externally paced field tests are widely used in cystic fibrosis (CF), it is still unclear whether they induce clinically relevant and similar cardiorespiratory responses. The aim of this study was therefore to compare the incremental shuttle walk test (ISWT) and 6 min walk test (6MWT), and to determine the factors influencing exercise capacity in CF. ⋯ The ISWT is a better reflection of exercise tolerance in CF than 6MWT. ISWT is a preferable alternative assessment of exercise tolerance in terms of cardiorespiratory response.
