Cord Blood Platelet Gel as a Treatment of Occipital Pressure Injuries in Newborns: Report of Two Cases

Why might cord blood be a better source of platelets for transfusion to neonates?

Thrombocytopenia (defined as a platelet count <150×109/L) is a common condition in preterm neonates and may occur in 18-35% of all infants admitted to the Neonatal Intensive Care Unit (NICU). Neonatal platelet functionality in terms of reactivity is often described as reduced compared to adults, even in healthy, term neonates. However, this platelet "hyporeactivity" does not correspond to a global functional impairment of the normal delicately balanced neonatal hemostatic system. The extent to which neonatal thrombocytopenia and platelet hyporeactivity contribute to the bleeding risk in preterm neonates remains unknown. Prophylactic platelet transfusions are often administered to them to reduce the risk of bleeding. However, recent literature indicates that adopting a higher platelet transfusion threshold than a lower one results in significantly higher death rates or major bleeding and can be harmful. Although the mechanism by which this occurs is not entirely clear, a mismatch between adult transfused platelets and the neonatal hemostatic system, as well as volume overload, are speculated to be potentially involved. Therefore, future research should consider novel transfusion products that may be more suitable for premature neonates. Blood products derived from umbilical cord blood (UCB) are promising, as they might perfectly match neonatal blood features. Here, we discuss the current knowledge about UCB-derived products, focusing on UCB-derived platelet concentrates and their potential for future clinical application. We will discuss how they may overcome the potential risks of transfusing adult-derived platelets to premature infants while maintaining efficacy.

Hospital-acquired skin lesions in the neonatal intensive care unit: A retrospective analysis of temporal trends and quality improvement strategies

PURPOSE

Skin lesions in neonatal population are an emerging problem deserving attention from health care professionals. The purpose of this study is to retrospectively assess the incidence of hospital-acquired skin lesions during a 6-year period and to describe the characteristics of infants who developed them.

DESIGN AND METHODS

This was a retrospective observational study conducted in a university-tertiary care center between 2015 and 2020. A descriptive analysis of the observed skin lesions is presented according to 2 time periods: 1) the implementation phase of a quality improvement program (2015-2019) and 2) the postimplementation phase (2020).

RESULTS

Our findings showed an apparent increase in the incidence of all reported skin lesions throughout the study period. Pressure injuries were the most frequently reported skin lesions showing an increasing incidence over time which, however, was paralleled by a reduction in their severity. Among pressure injuries, device-related injuries were the most commonly observed (56.6% and 62.5% in the two periods, respectively) with nasal continuous positive airway pressure-related injuries accounting for 71.7% and 56.0% of lesions, respectively, and mainly affecting the nose root. The occipital area was the most frequently involved site in cases of conventional pressure injuries.

CONCLUSION

Infants admitted to Neonatal Intensive Care Units may be at high risk of developing skin lesions. The adoption of appropriate preventative as well as treatment interventions could be effective in reducing the severity of pressure injuries.

PRACTICE IMPLICATIONS

The implementation of quality improvement strategies may contribute to prevent skin injuries or lead to their early detection.

Impressive Nasal Septum Regeneration after Cord Blood Platelet Gel (CBPG) in Extreme Premature Neonate with Non-Invasive Ventilation: A Case Report

BACKGROUND

We evaluated the efficacy of Cord Blood Platelet Gel (CBPG) in the regenerative reconstruction of the nasal septal tissue of a preterm infant undergoing non-invasive ventilation.

METHODS

A CBPC treatment was used to enhance the regeneration of the nasal septum of a premature patient in an experimental way, evaluating the efficacy described in the literature (selective bibliographic search in PubMed) of the use of blood products for non-transfusion purposes.

RESULTS

A partial but satisfactory regeneration of the patient's nasal septum was observed. Using the free NIH Image J online software, we were able to calculate the regenerated surface (about 83% of the destroyed cartilage).

CONCLUSIONS

The use of platelet gel has been a promising alternative to surgical treatment in patients with severe damage to the nasal septum.

Carboxymethyl Cellulose-Based Hydrogel Film Combined with Umbilical Cord Blood Platelet gel as an Innovative Tool for Chronic Wound Management: A Pilot Clinical Study

Treatment of chronic leg ulcers remains a major challenge and it is a substantial financial burden on individuals, families, caregivers, and health care system. There is increasing evidence on using of autologous Platelet-rich-plasma in wound repair but limited clinical data are available on the efficacy and safety of the use of umbilical cord blood platelet gel (CBPG). In our pilot study, for the first time, we aimed to evaluated the safety and efficacy of the use of umbilical CBPG combined with a hydrogel dressing in 10 patients with chronic venous ulcers (VU). The protocol consisted of application of umbilical cord blood platelet-rich plasma (PRP) combined with a Carboxymethyl cellulose (CMC)-based hydrogel dressing once a week for 4 weeks. The 80% of patients after 4 weeks of treatment had a significantly decrease in wound size. Moreover, we obtained an improvement in terms of mean Wound Bed Score (WBS), numeric rating scale (NRS) value and the EQ-5D index score. This pilot study showed that the topically therapeutic administration of umbilical CBPG associated with a CMC-based hydrogel dressing has the potential to accelerate the healing of chronic lesions without adverse reaction. However, additional studies with larger sample size and longer follow-up periods are required to confirm our findings.
