AbstractRetinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD) are diseases that occur only in preterm infants. The etiology of these disorders is multifactorial; however, it is believed that some of the factors in children presenting with BPD affect both the initiation and severity of ROP. The aim of the study was to evaluate the degree of clinical severity of ROP in infants with BPD compared to those without BPD.MethodologyInfants were divided into two groups: the BPD+ study group and BPD- control group. Parameters including the incidence of ROP and its severity were compared.ResultsIn neonates with BPD, more severe forms of ROP occurred significantly more frequently than in infants without BPD. Newborns with BPD required significantly longer use of mechanical ventilation; moreover, the number of days in which the concentration of oxygen in the respiratory mixture exceeded 50% was greater in BPD+ children . Children with BPD also received more blood transfusions compared to children without BPD.ConclusionsNewborns in the BPD+ study group showed advanced stages of ROP more often than newborns in the BPD- control group. The etiology of ROP and BPD is multifactorial; however, our findings suggest oxygen plays a significant role in the development of these diseases.

Od czasów powstania Internetu komunikacja przybierała już różne, nowe formy. Szczególne zmiany w tym temacie poczyniły media społecznościowe. Obecnie popularnym sposobem wyrażania siebie są Reelsy, czyli filmiki dostępne w serwisie Instagram. Artykuł stanowi próbę przeglądu Reelsów, w których została podjęta tematyka podróży i sportu.

Soviet and Jewish history. This study may be more urgently needed by its German audience, where it also serves as an introduction to a topic that, for English readers, has been covered in several monographs by such authors as Benjamin Pinkus, Zvi Gitelman, and Nora Levin. Vetter bases his thesis on newly recovered material, but his work does not constitute a dramatic deviation from previous scholarship. A limiting of the topic might have resulted in an even more original and innovative contribution but, notwithstanding the sometimes general statements, future scholars will undoubtedly have to consult this work in their evaluation of a crucial period in Soviet history.
