Digital Ischemia in an Extreme Preterm Infant Treated with Nitroglycerin Patch.

Ischemic limb lesions occasionally occur in neonates admitted to neonatal intensive care units. Known risk factors include the placement of arterial catheters, arterial punctures to obtain blood samples, and the use of vasoactive/vasopressor medications for hypotension. Prolonged peripheral tissue ischemia may result in serious complications, and successful management depends on early detection, proper assessment, and the institution of appropriate intervention. Currently, there is no standard approach for the management of peripheral tissue ischemia in extreme preterm infants. Topical nitroglycerine use is one of the promising options used to manage ischemic limb injuries in neonates, as demonstrated in several case reports. We report a case of digital ischemia in an extreme preterm infant with no clear risk factors except extreme prematurity, which recovered after topical nitroglycerine therapy.

Noninvasive Neurally Adjusted Ventilation versus Nasal Continuous or Intermittent Positive Airway Pressure for Preterm Infants: A Systematic Review and Meta-Analysis.

The noninvasive neurally adjusted ventilatory assist (NIV-NAVA) is a newly developed noninvasive ventilation technique with promising clinical and ventilatory outcomes for preterm infants. This systematic review and meta-analysis aimed to investigate whether NIV-NAVA has better clinical and ventilatory outcomes than nasal continuous airway pressure (NCPAP) or noninvasive positive pressure ventilation (NIPP) on premature infants. MEDLINE, Embase, and CENTRAL were searched, and randomized controlled trials (RCTs) that compared NIV-NAVA with NCPAP or NIPP for preterm infants (gestational age: <37 weeks) were included. We evaluated the following outcomes in the neonatal intensive care unit: the desaturation rate, failure of noninvasive modality requiring intubation when received as the primary mode or the need for re-intubation after extubation from mechanical ventilation in the secondary mode (weaning), length of stay, and fraction of inspired oxygen. The mean difference and risk ratio were used to represent continuous and dichotomous outcomes, respectively. We included nine RCTs involving 339 preterm infants overall. NIV-NAVA showed similar clinical and ventilatory outcomes to NCPAP or NIPP, except for the maximum diaphragmatic electrical activity. The rate of failure of the noninvasive modality was not statistically different between NIV-NAVA and NCPAP. The pooled estimates for the maximum electrical activity were significantly reduced in NIV-NAVA compared with those in NIPP. The findings suggest that NIV-NAVA may be as safe and effective as NCPAP and NIPP for preterm neonates, particularly those who may not tolerate these alternative noninvasive methods. However, further trials are recommended for greater evidence.

Incidence of Inborn Errors of Metabolism in Newborn Infants: Five Years' Single-Center Experience, Jeddah, Saudi Arabia.

Inborn errors of metabolism (IEMs) are inherited biochemical/metabolic disorders that are commonly present in the immediate neonatal period. The aim of this retrospective study was to determine the incidence and distribution of IEMs in newborn infants delivered in our hospital and to evaluate its outcome. A total of 16 494 (99.9%) newborn infants were screened for IEMs. We found 29 newborn infants diagnosed with IEMs, representing an incidence of 1 per ~569 live births and a cumulative incidence of 176 per 100 000 live births of the IEM-positive newborn infants. We detected 11 different types of IEMs, and the top 6 categories were endocrinopathies followed by carbohydrates disorders, vitamin-responsive disorders, organic acid defects, and ketogenesis and ketolysis defects. This study does reflect upon the importance of educating the general population about the perils of Consanguineous Marriages (CMs) in order to reduce related disorders significantly, especially in families who have a history of IEMs.

Jeddah Retinopathy of Prematurity (JED-ROP) Screening Algorithm.

Background. The Jeddah retinopathy of prematurity (JED-ROP) algorithm, which is more specific to the population in Saudi Arabia, was established to decrease the number of infants screened without missing type 1 ROP cases. Methods. The data reviewed were birth weight (BW), gestational age (GA), weekly postnatal weight gain (PWG), and relevant perinatal risk factors. The sensitivities and specificities for detecting type 1 ROP were calculated. Results. Of the 502 infants included in the study, 148 developed ROP. The JED-ROP algorithm demonstrated 100% sensitivity and 38.9% specificity for recommending the screening of infants with GA ≤30 weeks and BW <1501 g and blood transfused <6 weeks and/or 3-week PWG <100 g in the type 1 ROP group. Conclusion. The JED-ROP algorithm can reduce the number of infants requiring ROP screening by 35.7% without missing type 1 ROP. The algorithm can be an adjunct to current national screening guidelines.

Improving COVID-19 vaccine uptake: lessons from an academic institution in Saudi Arabia.

Background: Rejection, hesitancy and low uptake of the COVID-19 vaccine are major public health challenges in Saudi Arabia. Aims: To address COVID-19 vaccine hesitancy and rejection at the King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS) using evidence-based strategies. Methods: A questionnaire was administered electronically to participants at KSAU-HS to understand the reasons for vaccine hesitancy or rejection and develop an evidence-informed vaccination plan. Initial results from March 2021 showed that only 60% of respondents had taken at least 1 COVID-19 vaccine dose. Based on the results of the survey, KSAU-HS designed a 6-month vaccination campaign to raise awareness about the vaccine and its importance and increase acceptability rates. Mass media, social media, and direct messaging as reminders were used to address the barriers identified and to help the university community overcome fears and misconceptions about the COVID-19 vaccine. Results: The evidence-based interventions helped achieve a significantly high vaccination rate in the university community, with 99.7% of individuals vaccinated by October 2021; one of the highest vaccination rates among public universities in Saudi Arabia. Conclusion: Evidence-based interventions targeted at specific populations can help address prevailing concerns about the COVID-19 vaccine and other similar public health issues.

Assessment of mental health and various strategies among Health Professions' (HP) students: A cross sectional study in King Saud Bin Abdulaziz University for Health Sciences.

BACKGROUND: The education environment of medical colleges is known to have a burdensome effect on the overall mental health of the students. This study aimed to investigate the immediate impact of the medical education environment on mental health and quality of life among Health Profession students and to identify various coping strategies used by students to mitigate the stress. MATERIALS AND METHODS: An online survey was conducted between April 1 and May 10, 2021, using a validated questionnaire based on DASS-42, employing a snowball sampling technique. RESULTS: A total of 338 students filled the questionnaire. The respondents had a high level of depression and anxiety scores, categorized as very severe which were significantly different among level of education (P < .05), for example, 88.9% of sixth year students had very severe depression compared to just 37% of first year ones. Gender-wise very severe scores varied from lowest 45.8% to 70.3% with comparable results for both males and females. Additionally, more than 30% of the students listed that the amount of material to be covered, lack of time to study the material to be tested, heavy demand to study, concern about trying to learn all the content, and competitiveness among students to be the top reason which affect their mental state of mental health. CONCLUSIONS: This study identifies the need to provide the free professional and psychological services to help cope with stress to the health profession students.

Clinical and diagnostic characteristics of complex III mitopathy due to novel BCS1L gene mutation in a Saudi patient.

BACKGROUND: Of the many types of mitochondrial diseases, mutations affecting BCS1L gene are regarded as chief cause of the defective mitochondrial complex-III, affecting normal mitochondrial functioning, and leading to wide variety of phenotypes. CASE PRESENTATION: In this case report we describe a novel genotype linked to a unique phenotype in a Saudi patient born of a consanguineous marriage. Detailed genetic analysis and whole genome sequencing identified a novel homozygous missense mutation in exon 5 c.712A > G (p.Ser328Gly) of the BCS1L gene, with predicted deleterious effects on the functioning AAA+-ATPase domain of the protein characterized by distinct clinical presentation associated with profound multisystem involvement, conductive hearing loss, absent external auditory canal, low posterior hair line, short neck, micro and retrognathia, over riding fingers, rocker bottom foot, small phallus with bilateral absent testis (empty scrotum) and intolerable lactic acidosis. CONCLUSIONS: A pathogenic effect of this novel BCS1L mutation was reflected in the patient with his failure to thrive and a complex clinical and metabolic phenotype.

Age related reference ranges of heart rate for Saudi children and adolescents.

OBJECTIVE: To evaluate the resting heart rate to define reference values for healthy Saudi children and adolescents. METHODS: To establish representative heart rate (HR) reference values for Saudi Arabian children and adolescents, a sample of children, and adolescents was selected by multi-stage probability sampling of the Saudi population from birth to 20 years of age. The selected sample represents Saudi children from the whole country. Data were collected by a house-to-house survey of all selected households in all the 13 regions in the country. A total of 10,458 Saudi children were included in the study. The HR was measured by oscillometric-automated devices. Upper and lower reference values of the HR in boys and girls were calculated as mean +/= 2 SD. The study is cross-sectional, community based, and conducted over 2 years (2004-2005). Data management and analysis were performed in the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia. RESULTS: Determination of the HR values in a sample representing healthy Saudi children and adolescents from birth to 20 years of age. CONCLUSION: The present study provides age-specific reference values for heart rate (HR) of Saudi children and adolescents based on a large study sample. The use of these standards should aid the identification of children with abnormal HR.

The prevalence of sickle cell disease in Saudi children and adolescents. A community-based survey.

OBJECTIVE: To determine the prevalence and regional distribution of sickle cell disease in Saudi children. METHODS: A sample size of 45,682 children and adolescents from newborn to 19 years of age was selected by multistage random probability sampling of the Saudi households from each of the 13 regions of the country. The study is cross-sectional, community based, and conducted over 2 years from 2004 to 2005. Data, including history and clinical examination were collected with house-to-house survey of all selected households. Data management and analysis was carried out at King Saud University, Riyadh, Saudi Arabia. RESULTS: Sickle cell disease was detected in 108 of 45,682 children and adolescents with a prevalence of 24 per 10,000. The regional distribution of sickle cell disease showed eastern region dominance with a prevalence of 145 per 10,000, followed by the southern region with a prevalence of 24 per 10,000, western region 12 per 10,000, and central region with 6 per 10,000. No cases were found in the northern regions. The male to female ratio was approximately 1:1. CONCLUSION: The results of this national wide community-based survey show a high prevalence of sickle cell disease in the community and the disease is more common in eastern and southern regions of the country. National or regional newborn screening programs for sickle cell disease using hematological tests should be planed. This study shows that the population at risk has an uneven geographical distribution. For this reason, selective rather than universal neonatal screening is likely to be more appropriate in the country.
