Objective: The diagnosis of childhood acute lymphoblastic leukemia (ALL) and the subsequent treatment-related challenges impact the children's health-related quality of life (HRQoL) and parental distress (psychological morbidity and traumatic stress symptoms). This study examined the relationship between parental distress and children's HRQoL, focusing on preschool-aged children and toddlers. The aims were: to assess changes in children's HRQoL over time, compare HRQoL between children with ALL and healthy children, and evaluate the longitudinal association between parental distress and children's HRQoL.

Atrial fibrillation (AF) and cognitive decline represent significant health challenges with increasing prevalence and significant socioeconomic implications. Emerging evidence suggests a potential link between AF and cognitive decline, including dementia and Alzheimer's disease, although the underlying mechanisms remain incompletely understood. Inflammation has emerged as a key mediator in cardiovascular and neurological diseases, encouraging an investigation into its role in the atrial fibrillation-cognition association.

Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with intense treatments affecting both children and their families. Limited information is available on parental distress and psychological well-being during the first treatment year, with most studies focusing on individuals rather than the family system. This study explores longitudinal changes in parental distress (psychological morbidity and traumatic stress symptoms), coping strategies, family resilience and functioning, and psychological well-being.

Monochorionic twin pregnancies carry a risk of perinatal complications due to shared placental anastomoses, which can cause uneven blood distribution and lead to conditions like selective fetal growth restriction (sFGR). This case describes a monochorionic pregnancy complicated by preeclampsia and late-onset sFGR of twin B. Labor was prematurely induced and a 45% weight discordance between the twins was confirmed.

Late-onset sepsis (LOS) is commonly associated with pathogens acquired in hospital or community settings and carries a significant risk of morbidity and mortality in neonates. We present a case of a late preterm neonate, born at 36 weeks and 2 days with low birth weight (1700 g), who was admitted to the neonatal intensive care unit (NICU) and developed LOS on the fourth day of life. LOS was diagnosed in the context of fever and lethargy, mild thrombocytopenia, leukopenia, and lymphopenia, and was caused by multidrug-resistant (MDR) , confirmed through blood culture.

Article Synopsis
  • This study explores how hypothyroidism affects the development of pulmonary arterial hypertension (PAH) in male Wistar rats using a monocrotaline to induce PAH and methimazole to induce hypothyroidism.
  • Results showed that hypothyroid rats (MMZ + MCT group) had improved heart function and reduced right ventricular pressure compared to PAH rats (MCT group), while both groups had lower thyroid hormone levels.
  • The conclusion indicates that hypothyroidism may help mitigate mitochondrial dysfunction and slow down the progression of PAH caused by monocrotaline.

Parental burnout (PB) is characterised by parental exhaustion resulting from exposure to chronic parental stress. Due to the social and economic changes resulting from the COVID-19 pandemic that impacted families, there is a significant scientific interest in identifying factors related to PB within the pandemic context. This study aimed to analyse the relationships between parental stress (parental concerns, parental satisfaction, lack of control, and fears and anxieties), family functioning, psychological morbidity (anxiety and depression), and burnout in parents.

In Portugal, there are few generic and specific instruments to assess health-related quality of life (HRQoL) in children, especially those of preschool age. This study aimed to adapt and validate the Portuguese version of the Preschool Children Quality of Life Questionnaire (TAPQoL) in a community and clinical sample of children aged 0-6 years. The parents of 409 healthy children and 137 children undergoing treatment for burns and acute lymphoblastic leukemia completed the TAPQoL and were assessed on psychological morbidity and family functioning.

The cheese rind is the natural food packaging of cheese and is subject to a wide range of external factors that compromise the appearance of the cheese, including color defects caused by spoilage microorganisms. First, eight films based on whey protein isolate (WPI) coatings were studied, of which IS3CA (WPI 5% + sorbitol 3% + citric acid 3%) was selected for presenting better properties. From the IS3CA film, novel films containing melanin M1 (74 µg/mL) and M2 (500 µg/mL) were developed and applied to cheese under proof-of-concept and industrial conditions.

Purpose: In the present study, the therapeutic efficacy of a selective BK channel opener (compound X) in the treatment of monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH) was investigated.

Methods: PAH was induced in male Wistar rats by a single injection of MCT. After two weeks, the MCT-treated group was divided into two groups that were either treated with compound X or vehicle.

Objective: Teaching basic life support to schoolchildren is well established as one of the most effective strategies in increasing bystander CPR rates. However, there is a lack of scientific evidence concerning the Portuguese pediatric population. The present study aims to evaluate the outcome of a basic life support training session on theoretical knowledge and self-efficacy, immediately after the training and 6 months later, in a pediatric population.

Introduction: The purpose of this study was to assess the neonatal morbidity and mortality associated with vacuum-assisted vaginal deliveries compared to all other vaginal deliveries, and to identify the associated risk factors.

Material And Methods: We conducted a retrospective case-control study in a level iii maternity hospital between 2012 and 2016, including 1,802 vacuum-assisted vaginal deliveries and 2control groups: 1802 spontaneous deliveries and 909 forceps-assisted deliveries. We considered minor complications (soft tissue trauma, cephalohaematoma, jaundice, intensive phototherapy, transient brachial plexus injury) and major complications (hypoxic-ischaemic encephalopathy, intracranial and subgaleal haemorrhage, seizures, cranial fracture, permanent brachial plexus injury), admission to the neonatal intensive care unit and death.
