Extended minimal enteral feeding and time to regain birth weight in extremely low-birth-weight infants.

Background: Minimal enteral feeding after birth has been developed as a strategy to enhance the functional maturation of the gastrointestinal tract. This study aimed to examine the relationship between the duration of minimal enteral feeding and time to regain birth weight in extremely low-birth-weight infants.

Methods: This retrospective study included all extremely low-birth-weight infants born between January 2018 and December 2020.

Characterization of a Dual Nonlinear Helmholtz Resonator.

Resonant elements can generate small amounts of energy that make them pertinent for feeding miniaturized accelerometers with the energy needed. Suitable oscillator candidates are Helmholtz resonators, which have been, for a long time, analyzed and designed within the context of linear vibration. This study focuses on extracting nonlinear characteristics of a dual Helmholtz resonator (HR), with a neck-cavity-neck-cavity configuration, mounted on an acoustic waveguide with harmonically oscillating pressure.

Prolonged empiric antibiotics and time to full enteral feed in preterm infants less than 29 weeks of gestational age.

Background: Early empiric antibiotic exposure appears to negatively influence feeding tolerance in preterm infants. However, the effect of prolonged antibiotic treatment is unknown. The objective of this study was to investigate whether prolonged antibiotics impact the time to full enteral feed in infants less than 29 weeks of gestational age with negative blood cultures.

Patient and prescriber factors and the prolongation of antibiotics after birth in infants less than 29 weeks.

Objective: The objective of this study is to delineate whether patient-related or prescriber-related factors account for the prolongation of antibiotic therapy beyond 48 h in premature infants whose initial blood cultures are negative.

Methods: Retrospective review of infants born <29 weeks born between January 2011 and December 2012. Infants who had positive blood cultures or who died in the first 48 h were excluded from analysis.

Perceived core procedural skills for Nebraska family physicians.

We conducted a mail survey of 287 practicing family physicians, 22 family practice faculty, and 60 family practice residents in both rural and urban Nebraska concerning their perceptions of "core" procedures in family medicine and their perceived competency in performing them. Final response rate was 45%. There was general agreement concerning what constituted the core procedures in family medicine, although several newer procedures, such as flexible sigmoidoscopy, provoked more controversy.
