Objective: To determine the changes in serum C-reactive protein (CRP) levels during therapeutic hypothermia.
Study Design: Between January 2011 and June 2013, 133 hypoxic-ischemic encephalopathy patients being followed up in the neonatal intensive care unit of Dr. Sami Ulus Maternity and Children's Hospital are prospectively evaluated. Group 1; patients that received therapeutic hypothermia (n = 74) and group 2; patients that did not required therapeutic hypothermia (n = 59). All the patients underwent serial complete blood cell count and CRP assessments; blood cultures were obtained from all the cases at the time of admission and when CRP levels were elevated.
Results: Positive blood cultures were encountered in five cases (6.7%) in group 1 while no blood culture-proven septicemia was encountered in group 2. The CRP levels elevated gradually reaching a peak level on the 4th day and then decreased during the therapeutic hypothermia in patients with no blood culture-proven septicemia in group 1. The CRP levels showed statistically significant changes reaching a peak level on the 7th day in patients with blood culture-proven septicemia in group 2. Also, the CRP levels showed no alteration with time in group 2.
Conclusion: Therapeutic hypothermia itself might be associated with CRP elevation rather than an actual infection.

Redirection of Care for Neonates with Hypoxic-Ischemic Encephalopathy Receiving Therapeutic Hypothermia.
J Clin Med

Newborn Research, Department of Neonatology, University Hospital Zurich, CH-8091 Zurich, Switzerland.
: Hypoxic-ischemic encephalopathy (HIE) in late preterm and term neonates accounts for neonatal mortality and unfavorable neurodevelopmental outcomes in survivors despite therapeutic hypothermia (TH) for neuroprotection. The circumstances of death in neonates with HIE, including involvement of neonatal palliative care (NPC) specialists and neurodevelopmental follow-up at 18-24 months in survivors, warrant further evaluation. : A retrospective multicenter cohort study including neonates ≥ 35 weeks gestational age with moderate to severe HIE receiving TH, registered in the Swiss National Asphyxia and Cooling Register between 2011 and 2021.

Aim: Few studies have investigated the differential effects of targeted temperature management (TTM) according to the severity of the condition in pediatric patients with post-cardiac arrest syndrome (PCAS). This study was aimed at evaluating the differential effects of TTM in pediatric patients with PCAS according to a risk classification tool developed by us, the rCAST.
Methods: We used data from a nationwide prospective registry for out-of-hospital cardiac arrest (OHCA) patients in Japan.
Mechanistic Insights into Melatonin's Antiarrhythmic Effects in Acute Ischemia-Reperfusion-Injured Rabbit Hearts Undergoing Therapeutic Hypothermia.
Int J Mol Sci

Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Taoyuan Branch, Taoyuan 33304, Taiwan.
The electrophysiological mechanisms underlying melatonin's actions and the electrophysiological consequences of superimposed therapeutic hypothermia (TH) in preventing cardiac ischemia-reperfusion (IR) injury-induced arrhythmias remain largely unknown. This study aimed to unveil these issues using acute IR-injured hearts. Rabbits were divided into heart failure (HF), HF+melatonin, control, and control+melatonin groups.

Methods: A structured questionnaire was utilized, along with demographic and perinatal data obtained from the Hellenic Statistical Authority.
Results: Between 2004 and 2022, live births decreased by 28%, while the prematurity rate rose from 6.
Effects of Therapeutic Hypothermia and Minimal Enteral Nutrition on Short-Term Outcomes in Neonates with Hypoxic-Ischemic Encephalopathy: A 10-Year Experience from Oman.
Children (Basel)
December 2024
Department of Neonatology, Khoula Hospital, Mina Al Fahal, Muscat 116, Oman.
Background: Therapeutic hypothermia (TH) is the standard treatment for moderate to severe hypoxic-ischemic encephalopathy (HIE) in developed countries, but data on its safety and efficacy in low-middle-income countries are limited and often conflicting. The impact of enteral feeding during TH remains inadequately explored. We aimed to examine TH's effects on mortality and brain injury and evaluate the safety and effectiveness of minimal enteral feeding during TH.
