Hyperbaric oxygen therapy for the treatment of neonatal hypoxic-ischemic brain damage has been used clinically for many years, but its effectiveness remains controversial. In addition, the mechanism of this potential neuroprotective effect remains unclear. This study aimed to investigate the influence of hyperbaric oxygen on the proliferation of neural stem cells in the subventricular zone of neonatal Sprague-Dawley rats （7 days old） subjected to hypoxic-ischemic brain damage. Six hours after modeling, rats were treated with hyperbaric oxygen once daily for 7 days. Immunohistochemistry revealed that the number of 5-bromo-2＇-deoxyuridine positive and nestin positive cells in the subventricular zone of neonatal rats increased at day 3 after hypoxic-ischemic brain damage and peaked at day 5. After hyperbaric oxygen treatment, the number of 5-bromo-2＇- deoxyuddine positive and nestin positive cells began to increase at day 1, and was significantly higher than that in normal rats and model rats until day 21. Hematoxylin-eosin staining showed that hyperbaric oxygen treatment could attenuate pathological changes to brain tissue in neonatal rats, and reduce the number of degenerating and necrotic nerve cells. Our experimental findings indicate that hyperbaric oxygen treatment enhances the proliferation of neural stem cells in the subventricular zone of neonatal rats with hypoxic-ischemic brain damage, and has therapeutic potential for promoting neurological recovery following brain injury.

Introduction: Despite advances in obstetrics and pediatrics over the past 20 years, premature birth remains an unpredictable event that can have a devastating impact on parenthood. This study aimed to analyze the psycho-affective experiences of fathers of premature newborns. Methods: This was a descriptive cross-sectional study, carried out in the department of neonatology and neonatal intensive care unit of the CHU Mohamed VI in OUJDA, over 6 months from March 2022 to August 2022. It focused on 30 fathers of premature newborns hospitalized in our department. Results: The majority of fathers described a state of fear and stress, and attributed their negative experience to the unexpected nature of the premature birth. At the first meeting, half the fathers had a positive image of their newborn’s physical appearance, while 22% of fathers reported feeling uncomfortable about their newborn’s low weight. Most fathers reported that they appreciated the welcome they received, the skill with which they cared for their newborn, and the availability of the pediatrician to provide information on their child’s state of health. Two fathers enjoyed skin-to-skin contact with their newborns. None of the fathers met a psychologist. When they returned home, half the fathers had a positive outlook, marked by happiness at being able to fully invest in their role as fathers, the other half reported being torn between the desire to see their child integrated into the family cocoon and the fear of not being able to manage delicate situations properly without a medical team. Conclusion: Bringing a premature baby into the world can be a difficult experience, leading to the development of even minor psychological distress in some fathers, and hence the need for specific psychological care.

AIM To perform a meta-analysis of the related studies to assess whether circulating tumor cells(CTCs) can be used as a prognostic marker of esophageal *** Pub Med, Embase, Cochrane Library and references in relevant studies were searched to assess the prognostic relevance of CTCs in patients with esophageal cancer. The primary outcome assessed was overall survival(OS). The meta-analysis was performed using the random effects model, with hazard ratio(HR), risk ratio(RR) and 95% confidence intervals(95%CIs) as effect *** Nine eligible studies were included involving a total of 911 esophageal cancer patients. Overall analyses revealed that CTCs-positivity predicted disease progression(HR = 2.77, 95%CI: 1.75-4.40, P < 0.0001) and reduced OS(HR = 2.67, 95%CI: 1.99-3.58, P < 0.00001). Further subgroup analyses demonstrated that CTCs-positive patients also had poor OS in different subsets. Moreover, CTCs-positivity was also significantly associated with TNM stage(RR = 1.48, 95%CI: 1.07-2.06, P = 0.02) and T stage(RR = 1.44, 95%CI: 1.13-1.84, P = 0.003) in esophageal *** Detection of CTCs at baseline indicates poor prognosis in patients with esophageal cancer. However, this finding relies on data from observational studies and is potentially subject to selection bias. Prospective trials are warranted.

Congenital hernia of the diaphragmatic dome (CHDD) is an embryonic malformation in which all or part of the diaphragmatic dome fails to develop properly. In the majority of cases (80% to 90%), this malformation affects the left posterolateral part of the diaphragm, while in 10% to 15% of cases it affects the right. Bilateral cases are extremely rare, accounting for less than 1% of cases. This malformation is estimated to occur at a frequency of around 1 in 3500 births, with a male predominance. The diaphragmatic defect causes the abdominal organs to rise into the thoracic cavity during critical phases of lung development. These anomalies result in bilateral pulmonary hypoplasia, a reduced number of pulmonary vessels, and pulmonary arterial hypertension (PAH). The combination of these anatomical and functional anomalies, in varying degrees, explains the wide variability of symptoms at birth. Diagnosis is usually made prenatally by ultrasound, which enables severe forms of the disease to be detected and appropriate management initiated. The prognosis remains generally grave, with a neonatal mortality rate of between 30% and 60% depending on the study, and around half of all children will have long-term sequelae.
