As the usage of social media continues to grow and local governments expand their promotional efforts, more internet celebrity cities (ICCs) are emerging as popular tourist destinations. To investigate the internal mechanisms that affect tourists' travel intentions to such destinations, place attachment and perceived value were proposed as two factors reflecting their deeper emotional connections and practical assessments to visit ICCs. This study was conducted to examine the relationship between social media usage, perceived government market orientation (PGMO), place attachment, perceived value, and travel intention in the context of Chongqing, a popular ICC in China.

Using neurophysiological measures to model how the brain performs complex cognitive tasks such as mental rotation is a promising way towards precise predictions of behavioural responses. The mental rotation task requires objects to be mentally rotated in space. It has been used to monitor progressive neurological disorders.

Article Synopsis
  • The study explored the occurrence and causes of neonatal meningitis across multiple centers in the country, focusing on the risk factors, complications, and outcomes of affected newborns.
  • Out of 634 cases analyzed, the incidence was found to be 2.51 per 1000 ICU admissions, with a notable mortality rate of 23.5%, primarily caused by Gram-positive bacteria, especially coagulase-negative Staphylococci.
  • Key risk factors for increased mortality included respiratory distress requiring ventilatory support, low birth weight, and lack of antenatal steroid exposure, highlighting severe clinical conditions associated with poor outcomes.

Article Synopsis
  • - The study investigates the incidence of hypoxic ischemic encephalopathy (HIE) in infants ≥36 weeks gestational age in Turkey, finding an incidence rate of 2.13 per 1000 live births, with varying severity levels among those affected.
  • - Among infants with HIE, therapeutic hypothermia (TH) was notably administered to 34.5% of those with mild HIE, while factors like gestational age affected mortality rates, especially in those born at 34-35 weeks.
  • - Despite an unchanged incidence of HIE, the study revealed a decreased mortality rate and no significant impact of TH timing on MRI findings or mortality.

Real time electroencephalogram (EEG) based neurofeedback has been shown to be effective in regulating brain activity, thereby modifying cognitive performance and behavior. Nevertheless, individual variations in neurofeedback learning rates limit the overall efficacy of EEG based neurofeedback. In the present study we investigated the effects of learning rate and control over training realized by self-pacing on cognitive performance and electrocortical activity.

Objectives: The purpose of the study was to evaluate the effect of different treatment modalities on refractive outcomes in patients treated with severe retinopathy of prematurity (ROP).

Methods: The records of children who were treated for severe ROP in our clinic between January 2015 and August 2018 were retrospectively reviewed. The children who were treated were analyzed in three subgroups as intravitreal bevacizumab (IVB), laser photocoagulation (LPC), and IVB + LPC.

Article Synopsis
  • The study investigates late neonatal hypocalcemia (LNH) in Turkey, focusing on the link between LNH and vitamin D deficiency, which is common in newborns presenting with seizures.
  • Conducted across 61 neonatal centers, the research included 96 affected neonates and 93 mothers, analyzing various blood serum markers related to calcium and vitamin D levels.
  • Findings revealed that a significant majority of both neonates (86.5%) and mothers (93%) were vitamin D deficient, suggesting the need for improved vitamin D supplementation during pregnancy to help reduce cases of LNH.

Hemolytic disease of the fetus and newborn is a disease that is caused by maternal alloantibodies to the fetus. In the literature, the frequency of hemolytic disease of the newborn due to Rh (D) sensitization decreased inversely with the increase in the use of anti-D gammaglobulin. However, the importance of minor blood group incompatibilities has increased in the etiology.

Congenital syphilis is a severe disease that arises from the vertical transmission of Treponema pallidum. Clinical findings are related to the pregnancy stage, fetal gestational week, maternal treatment and fetal immunologic response. Prematurity, low birth weight, nonimmune hydrops fetalis, necrotizing enterecolitis, hepatomegaly, skin eruptions, thrombocytopenia, hemolytic anemia and fever can be detected in the symptomatic newborn.

The majority of abdominal masses detected in the neonatal period are benign (85%) and usually originate in the urinary tract (50%), genital system (15%), gastrointestinal system (15%), or the hepatobiliary tract (5%). Ovarian cysts comprise one-third of the masses with a genital origin. Presently described is a case of an ovarian cyst that developed during the antenatal period and transformed into a hemorrhagic cystic mass as a result of torsion.

Objectives: The aim of this study was to evaluate risk factors used for the assessment of neonatal hypoglycemia and to examine the follow-up outcomes observed in the first 48 hours of postnatal life.

Methods: The records of infants born between 2015 and 2017 (3 years) at Şişli Hamidiye Etfal Training and Research Hospital who had a blood glucose level test performed within the first 24 hours after birth and who had follow-up results for 48 hours were included in the study. Data of gestational age; birth weight; gender; antenatal, natal and postnatal characteristics; blood glucose measurement method and time during the first 48 hours postpartum; glucose values and follow-up; nutritional status; and the need for hospitalization due to a low blood glucose value were recorded.

Disorders of sex development are defined as conditions in which the chromosomal, gonadal, and anatomic sex is discordant. Patients usually present with atypical appearing genitalia. In the assessment of neonates with disorders of sex development, first, it is important to determine whether this situation requires prompt evaluation, and then the karyotype, hormone levels, and underlying etiology should be determined as soon as possible.

Developments in perinatal and neonatal care have increased the survival rate of high-risk newborns but led to a rise in chronic diseases seen in these infants. A significant number of them attend primary and secondary health care centers after discharge; however, there are very few standard protocols for the long-term follow-up of these babies. Therefore, we aimed to establish a follow-up guideline that emphasizes on universal screening schemes and takes into consideration national data.

Article Synopsis
  • * Convulsions in newborns are categorized into four types: subtle, clonic, tonic, and myoclonic, while non-epileptic movements such as jitteriness and sleep myoclonus can often be mistaken for seizures.
  • * Treatment for convulsions includes hospitalization and monitoring, with phenobarbital typically being the first-line medication, while the broader goal is to avert brain damage and tackle potential long-term neurological issues.
