RESUMEN
This study examined sickle cell disease (SCD) in Saudi Arabia. A systematic search of relevant databases was conducted to identify studies investigating SCD in the Saudi population. Studies were then screened based on predefined criteria and critically appraised for methodological quality. Data was extracted and synthesized to provide an overall picture of the SCD burden in Saudi Arabia. The most commonly reported complications were vaso-occlusive crises (VOC), acute chest syndrome (ACS), acute painful crisis, splenic sequestration, osteomyelitis, aplastic crisis, hemolytic crisis, serious bacterial infections, chronic vascular occlusion (CVO), depression, sickle cell nephropathy (SCN), obstructive sleep apnea (OSA), and renal complications. Reduced blood levels of antioxidant trace elements (Cu, Zn, and Se) may encourage oxidative stress, which in turn may contribute to the pathophysiology of SCD. Infections and ACS were common among young children (<7 years) while pain attacks were common in older children (>7 years). The high rate of hospitalizations among SCD patients highlights the need for better management strategies. Future research should focus on understanding the underlying causes of SCD complications and developing new ways to control them.
RESUMEN
This study aims to systematically review the existing literature on long-term cognitive outcomes in neonates with hypoxic-ischemic encephalopathy (HIE). A thorough search of PubMed, MEDLINE, and Embase was conducted to find studies that satisfied the inclusion requirements. Rayyan (Qatar Computing Research Institute, Doha, Qatar) was utilized during the whole operation. Our results included seven studies with a total of 521 patients and 247 (47.4%) were females. All of the included participants were assessed for the incidence of cognitive functions following hypothermia therapy. Newborns with significant HIE are at high risk for neurodevelopmental complications even in the absence of magnetic resonance imagining (MRI) abnormalities, such as poor performance score and hearing-language score, functional status, delayed language skills, emotional processing, sensory movement, learning, and memory. Independent of motor deficits, participants with a history of HIE are susceptible to issues with cognition and executive function during late childhood and adolescence. It is crucial to keep an eye on their intellectual development after infancy since cognitive dysfunction and memory problems might manifest subtly or not at all in the early years of life, but they can cause problems in later childhood and adolescence. Long-term follow-up research is also required to ascertain whether the enhanced cognitive outcomes will continue throughout adolescence. Even in cases where overt neuromotor abnormalities are not evident, children with watershed injuries on brain MRIs should be closely monitored to evaluate cognitive function, particularly language development.
RESUMEN
This study aims to comprehensively investigate the association between childhood asthma and gastroesophageal reflux disease (GERD) in children. A thorough search of pertinent databases was done in order to find studies that satisfied the requirements for inclusion. A thorough search of PubMed, Web of Science, SCOPUS, and Science Direct was conducted to find pertinent literature. Twelve studies, including a total of 176,678 patients - 91,447 (51.8%) of them were males - were included in our data. The prevalence of GERD in asthmatic children ranged from 0.7% to 65.3%, with a total prevalence of 3317 (3.6%). The included studies documented that GERD increases the chance of asthma, while asthma raises the risk of GERD. Obesity in asthmatic patients was an independent risk factor for the incidence of GERD. Controlling asthma is significantly impacted by comorbidities like obesity and GRED. The findings of our comprehensive review point to a possible link between juvenile patients with asthma who are referred to secondary and tertiary care facilities and having GERD. Nevertheless, the evidence for this link is weak in a number of situations. Lack of longitudinal research establishing the proper temporal sequence, studies indicating no severity-response relationship, and insufficient data showing a treatment-response relationship all contribute to the uncertainty around the nature and direction of the association. Our findings highlight the need for additional epidemiologic research to investigate the connection between GERD and asthma, including long-term follow-up.
