Aim: to compare the prevalence of exclusive breastfeeding (EBF) and to verify the factors associated with its interruption in premature infants hospitalized at Baby-Friendly hospitals. Method: this is a comparative study performed with 107 premature infants admitted to the neonatal unit of two hospitals in Paraná. Data were obtained through interviews with mothers and analysis of infant records at hospital discharge and 15 days after delivery. Results: the prevalence of EBF was 29.2% in the University Hospital and 15.3% in the Philanthropic Hospital. At hospital discharge, associations with clinical characteristics of infants predominated, and 15 days after discharge there was a greater association with the socio-demographic characteristics of the parents. Conclusion: the prevalence of EBF, which was shown to be low at the time of hospital discharge in both hospitals, decreased after discharge, reinforcing the need for other strategies, in addition to those provided at Baby-Friendly hospitals, for the promotion and support of EBF in preterm infants.

Abstract Capabilities in continuous monitoring of key physiological parameters of disease have never been more important than in the context of the global COVID-19 pandemic. Soft, skin-mounted electronics that incorporate high-bandwidth, miniaturized motion sensors represent a powerful class of technology for digital, wireless measurements of mechano-acoustic (MA) signatures of both core vital signs (heart rate, respiratory rate, and temperature) and underexplored biomarkers (coughing count) with high fidelity and immunity to ambient noises. Here, we introduce an effort that integrates such an MA sensor, a cloud data infrastructure and data analytics approaches based on digital filtering and convolutional neural networks for comprehensive monitoring of COVID-19 infections in sick and healthy individuals in a population, both in the hospital and the home. This hardware/software system extracts diverse signatures of health status in an automated fashion from a single device and time series data stream. Unique features are in quantitative measurements of coughing and other vocal events, as indicators of both disease and infectiousness. Systematic imaging studies demonstrate direct correlations between the time and intensity of coughing, speaking and laughing and the total droplet production, as an approximate indicator of the probability for disease spread. The sensors, deployed on COVID-19 patients along with healthy controls in both inpatient and home settings, record coughing frequency and intensity continuously, along with a comprehensive collection of other biometrics, with recording times for individuals of more than a month after disease diagnosis. These pilot studies include 3,111 hours of data spanning 363 days from 37 COVID-19 patients (20 females, 17 males) with 27,651 coughs detected in total along with continuous measurements of heart rate, respiratory rate, physical activity, and skin temperature. Manual labeling of randomly sampled 10,258 vocal events from 11 COVID-19 patients (6 females, 5 males) suggests a sensitivity of 85% and a specificity of 96% in cough detection using automated algorithms. The collective results indicate a decaying trend of coughing frequency and intensity through the course of disease recovery, but with wide variations across patient populations. The methodology also opens opportunities to study patterns in biometrics across individuals and among different demographic groups.

The Mean

Sixteen serial observations of oxygen consumption, carbon dioxide production, R.Q., respiratory rate, rectal temperature, and skin blood flow were made on six premature infants ranging in age from 3 hours to 12 days and weighing from 1.14 to 1.94 kg, utilizing a specially designed climatized chamber at neutral (32-34°C), low (21-23°C), and high (36-38°C) ambient temperatures. Ten premature infants ranging in age from 2½ hours to 18 days were studied at high (36-38°C) ambient temperature. At low ambient temperature, there was a mean increase of 63% in oxygen consumption even in infants under 24 hours of age. At the end of the rewarming period, rectal temperature, which had been lowered during a 20-minute exposure to 21-23°C, nearly recovered to the original level in infants in both of the age groups of 0 to 24 hours and 2 to 5 days, whereas in the 6 to 12 day old group, it returned faster than the former two and it was increased by 0.32 to 1.9°C (mean 0.9°C). At 36-38°C, ambient temperature, the mean oxygen consumption increased 18% in infants ages 2½ to 7½ hours, whereas there was no significant increase in infants ages 10 to 18 days. Sweating and significant vasodilatation generally did not occur even in the older infants. The respiratory rate was increased in most infants. It is suggested that heat loss through the respiratory tract might be important to the premature infant who has a lack of evaporative means at high ambient temperature.

Hypoxic State

The response to breathing 12 per cent oxygen by newborn premature and full-term infants and premature infants several weeks old has been studied. Comparisons show that newborn premature and full-term infants during the first days after birth failed to respond with increases in respiratory rate or tidal volume during the hypoxic state. In fact, there was some decrease in ventilation which was largely related to reductions in tidal volume. Premature infants several weeks old, on the other hand, showed an immediate and significant hyperpnea while breathing 12 per cent oxygen. The younger infants, particularly the premature infants, seemed to be less disturbed by the hypoxia than older infants. These results substantiated previous results obtained on full-term infants. The hypothesis was advanced that the chemoreceptor reflexes were less active immediately following birth than later on in life.

In the article by Bruce D. Ackerman, et al. in the June issue of Pediatrics, 45:918, 1970, the sentence beginning on line 2 of the left hand column of page 923 should be two sentences, which should read as follows: Case 6 did not show the spastic signs described by Van Praagh,28 but did show slowing of the respiratory rate and decreased depth of respiration. Case 4 showed these respiratory changes, in addition to spasticity.
