Exploring Ventilator-Associated Pneumonia: Microbial Clues and Biomarker Insights from a Retrospective Study.

Background and Objectives: Ventilator-associated pneumonia (VAP) is a common complication in critically ill patients receiving mechanical ventilation. The incidence rates of VAP vary, and it poses significant challenges due to microbial resistance and the potential for adverse outcomes. This study aims to explore the microbial profile of VAP and evaluate the utility of biomarkers and illness severity scores in predicting survival. Materials and Methods: A retrospective cohort study was conducted involving 130 patients diagnosed with VAP. Microbial analysis of bronchoalveolar lavage (BAL) fluid, as well as measurements of C-reactive protein (CRP) and procalcitonin (PCT) levels, were performed. Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were calculated to assess illness severity. Statistical analyses were conducted to determine correlations and associations. Results: The study revealed that Klebsiella pneumoniae (K. pneumoniae) (50.7%) and Pseudomonas aeruginosa (P. aeruginosa) (27.69%) were the most identified microorganisms in VAP cases. SOFA (p-value < 0.0001) and APACHE II (p-value < 0.0001) scores were effective in assessing the severity of illness and predicting mortality in VAP patients. Additionally, our investigation highlighted the prognostic potential of CRP levels (odds ratio [OR]: 0.980, 95% confidence interval [CI] 0.968 to 0.992, p = 0.001). Elevated levels of CRP were associated with reduced survival probabilities in VAP patients. Conclusion: This study highlights the microbial profile of VAP and the importance of biomarkers and illness severity scores in predicting survival. Conclusions: The findings emphasize the need for appropriate management strategies to combat microbial resistance and improve outcomes in VAP patients.

Antioxidant Activity of Vitamin C against LPS-Induced Septic Cardiomyopathy by Down-Regulation of Oxidative Stress and Inflammation.

In severe cases of sepsis, endotoxin-induced cardiomyopathy can cause major damage to the heart. This study was designed to see if Vitamin C (Vit C) could prevent lipopolysaccharide-induced heart damage. Eighteen Sprague Dawley male rats (n = 6) were divided into three groups. Rats received 0.5 mL saline by oral gavage in addition to a standard diet (Control group), rats received one dose of endotoxin on day 15 (lipopolysaccharide) (LPS) (6 mg/kg), which produced endotoxemia (Endotoxin group), and rats that received 500 mg/Kg BW of Vit C by oral gavage for 15 days before LPS administration (Endotoxin plus Vit C group). In all groups, blood and tissue samples were collected on day 15, six hours after LPS administration, for histopathological and biochemical analysis. The LPS injection lowered superoxide dismutase (SOD) levels and increased malondialdehyde in tissues compared with a control group. Furthermore, the endotoxin group showed elevated inflammatory biomarkers, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Both light and electron microscopy showed that the endotoxic-treated group's cardiomyocytes, intercalated disks, mitochondria, and endothelial cells were damaged. In endotoxemic rats, Vit C pretreatment significantly reduced MDA levels and restored SOD activity, minimized biomarkers of inflammation, and mitigated cardiomyocyte damage. In conclusion: Vit C protects against endotoxin-induced cardiomyopathy by inhibiting oxidative stress cytokines.

Assessment of depression in children and adolescents with Type 1 diabetes mellitus: Impact and intervention strategies.

Depression is a common comorbidity in children and adolescents with type 1 diabetes mellitus (T1DM), yet its prevalence, impact, and intervention strategies remain underexplored. This study aims to assess the prevalence of depression among children and adolescents with T1DM, investigate its impact on health outcomes, and explore potential intervention strategies. A convenient sampling method was employed to recruit 229 participants aged 6 to 18 years from a single center. Data collection involved validated assessments, demographic surveys, and diabetes-related factor examinations during routine clinic visits. The patient health questionnaire-9 was utilized to evaluate the severity of depressive symptoms. Associations between depression and sociodemographic variables, diabetes management factors, and health behaviors were analyzed using chi-squared tests and logistic regression analysis. The prevalence of depression among participants was 43.23%. Older age, lower parental education levels, lower household income, smoking, and comorbidities were identified as significant risk factors for depression. Associations were found between depression and diabetes management factors, including glycemic control and frequency of glucose monitoring. Depression is highly prevalent among children and adolescents with T1DM and is associated with sociodemographic factors, health behaviors, and diabetes management. Integrated approaches to care that address both physical and mental health aspects are crucial for improving outcomes in this population.

Community Perception and Attitude towards COVID-19 Vaccination for Children in Saudi Arabia.

INTRODUCTION: Vaccines are an important part of the COVID-19 pandemic response plan. This study was undertaken to find out the percentage of supporters in the Saudi population for COVID-19 vaccination among children, and to assess the study population's perceptions towards COVID-19 vaccination among children. MATERIAL AND METHODS: This nationwide study adopted a cross-sectional survey of adult participants, conducted by trained medical students. The anonymous questionnaire was published on social media tools. Statistical analysis was conducted using two-tailed tests. RESULTS: Six hundred and twenty (620) participants were recruited for this study. Nearly 17.0% of participants had a chronic health problem/comorbidity. About 28.7% of the study participants reported having COVID-19 infection. The COVID-19 vaccine was received among 94.7% of the study respondents. The majority of the vaccination supporters (89.0%) wanted to get the third dose. There was a statistically significant association between the participant's attitudes towards getting vaccinated themselves, and their attitude towards children's vaccination. Vaccine newness, as a reason for hesitating to get vaccinated, was most reported among non-vaccine supporters. False religious beliefs were found to significantly influence the opposing attitude towards children's vaccination. CONCLUSION: Health professionals and policy makers should implement and support strategies to ensure children are vaccinated against COVID-19. They also need to educate parents and families regarding the importance of vaccination against COVID-19.

Ultrasound Imaging in Subjects with Sickle Cell Disease: The Saudi Arabia Experiences.

Background: Abdominal organ sonography is a crucial part of the workup for treating sickle cell disease (SCD) patients. Objective: The main objective of this study was to evaluate the abdominal organs in SCD patients using ultrasonography. Methodology: A non-interventional descriptive cross-sectional study was carried out in Asir region Saudi Arabia from April 2019 to July 2020. The study was conducted in 78 patients with sickle cell disease (SCD). Data were gathered using a data collection sheet included demographic information, clinical information including medication types, and complications linked to SCD. Furthermore, the study evaluated abdominal ultrasound findings pertaining to the liver, gall bladder, spleen, and kidneys. The data were analyzed using Statistical Package for Social Sciences (SPSS). Results: More than half of the study participants 43 (55.1%) were females. About 53.8% of the study participants received blood transfusions, and (11.5%) receive extra-vaccine. Concerning ultrasound findings, hepatomegaly was found in seventeen (21.8%), focal liver lesions in four (5.1%), gallstones in five (6.4%), splenomegaly in fifteen (19.3%), and the presence of splenic focal lesions was found in seven (9.0%). The most frequent complication associated with SCD was osteomyelitis sepsis in six cases (7.7%). The study revealed a significant correlation between the type of crisis and type of medication used and the size of the spleen (P-value <0.01), and no notable correlation was found between the types of crises and the size of the liver (P-value >0.05). Conclusion: Abdominal sonography in SCD patients revealed a wide range of alterations in the liver, gallbladder, and spleen. The most frequently observed complications in SCD were hepatomegaly, splenomegaly, localized lesions in both organs, and the presence of gallstones.

Assessment of Parental Knowledge, Awareness, and Perception About Autism Spectrum Disorders in Aseer Region, Southwestern Saudi Arabia.

Background: Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects young children in social relatedness and communication besides other characteristics. A community's awareness and early intervention services in diagnosing and treating autistic children are essential for preventing the expected complications, eg language delay, social interaction, and intellectual ability. Aim: To assess the parent's knowledge and perceptions regarding autism and its associated clinical features and effects. Methodology: A cross-sectional study was conducted targeting all available parents aged 18 years or more living in Aseer region. Data were collected using a self-reported questionnaire from randomly selected parents who attended outpatient clinics at Abha Maternity and Children Hospital and Aseer Central Hospital. Parents' knowledge regarding autism was assessed covering general knowledge, clinical features, social effects, consequences, and curability. Results: A total of 477 parents participated. Parents' ages ranged from 18 to 85 years. 261 (54.7%) parents were male and 216 (45.3%) were females. Nearly 65.6% of parents were university graduates and 28.3% had a secondary level of education. About 50.9% of the parents know that genetics play a major role in causing autism, 69.6% think that most children with autism have special talents or abilities, 64.2% know that delayed language development is one of the main symptoms of autism, 61.2% also know that repetitive movements of the hands and head are a common symptom of autism. About 36.9% of parents think that diagnosing a child with autism will lead to discrimination against the child, 33.3% of parents think that autism is a rare condition in this country compared to the West. Conclusion: The study showed that parents had poor knowledge levels regarding autism and its related clinical features, especially male parents with low levels of education. On the other hand, their perception of the disease and its frequency in the study area was satisfactory.

A Comprehensive Pan-Cancer Analysis Identifies CEP55 as a Potential Oncogene and Novel Therapeutic Target.

Emerging research findings have shown that a centrosomal protein (CEP55) is a potential oncogene in numerous human malignancies. Nevertheless, no pan-cancer analysis has been conducted to investigate the various aspects and behavior of this oncogene in different human cancerous tissues. Numerous databases were investigated to conduct a detailed analysis of CEP55. Initially, we evaluated the expression of CEP55 in several types of cancers and attempted to find the correlation between that and the stage of the examined malignancies. Then, we conducted a survival analysis to determine the relationship between CEP55 overexpression in malignancies and the patient's survival. Furthermore, we examined the genetic alteration forms and the methylation status of this oncogene. Additionally, the interference of CEP55 expression with immune cell infiltration, the response to various chemotherapeutic agents, and the putative molecular mechanism of CEP55 in tumorigenesis were investigated. The current study found that CEP55 was upregulated in cancerous tissues versus normal controls where this upregulation was correlated with a poor prognosis in multiple forms of human cancers. Additionally, it influenced the level of different immune cell infiltration and several chemokines levels in the tumor microenvironment in addition to the response to several antitumor drugs. Herein, we provide an in-depth understanding of the oncogenic activities of CEP55, identifying it as a possible predictive marker as well as a specific target for developing anticancer therapies.

Loss of function mutation in LARP7, chaperone of 7SK ncRNA, causes a syndrome of facial dysmorphism, intellectual disability, and primordial dwarfism.

Primordial dwarfism (PD) is a clinically and genetically heterogeneous condition. Various molecular mechanisms are known to underlie the disease including impaired mitotic mechanics, abnormal IGF2 expression, perturbed DNA damage response, defective spliceosomal machinery, and abnormal replication licensing. Here, we describe a syndromic form of PD associated with severe intellectual disability and distinct facial features in a large multiplex Saudi family. Analysis reveals a novel underlying mechanism for PD involving depletion of 7SK, an abundant cellular noncoding RNA (ncRNA), due to mutation of its chaperone LARP7. We show that 7SK levels are tightly linked to LARP7 expression across cell lines, and that this chaperone is ubiquitously expressed in the mouse embryo. The 7SK is known to influence the expression of a wide array of genes through its inhibitory effect on the positive transcription elongation factor b (P-TEFb) as well as its competing role in HMGA1-mediated transcriptional regulation. This study documents a critical role played by ncRNA in human development and adds to the growing list of molecular mechanisms that, when perturbed, converge on the PD phenotype.

Etiology, Clinical Phenotypes, Epidemiological Correlates, Laboratory Biomarkers and Diagnostic Challenges of Pediatric Viral Meningitis: Descriptive Review.

Meningitis is an inflammation of the brain and spinal cord meninges caused by infectious and non-infectious agents. Infectious agents causing meningitis include viruses, bacteria, and fungi. Viral meningitis (VM), also termed aseptic meningitis, is caused by some viruses, such as enteroviruses (EVs), herpesviruses, influenza viruses, and arboviruses. However, EVs represent the primary cause of VM. The clinical symptoms of this neurological disorder may rapidly be observed after the onset of the disease, or take prolonged time to develop. The primary clinical manifestations of VM include common flu-like symptoms of headache, photophobia, fever, nuchal rigidity, myalgia, and fatigue. The severity of these symptoms depends on the patient's age; they are more severe among infants and children. The course of infection of VM varies between asymptomatic, mild, critically ill, and fatal disease. Morbidities and mortalities of VM are dependent on the early recognition and treatment of the disease. There were no significant distinctions in the clinical phenotypes and symptoms between VM and meningitis due to other causative agents. To date, the pathophysiological mechanisms of VM are unclear. In this scientific communication, a descriptive review was performed to give an overview of pediatric viral meningitis (PVM). PVM may occasionally result in severe neurological consequences such as mental retardation and death. Clinical examinations, including Kernig's, Brudzinski's, and nuchal rigidity signs, were attempted to determine the clinical course of PVM with various success rates revealed. Some epidemiological correlates of PVM were adequately reviewed and presented in this report. They were seen depending mainly on the causative virus. The abnormal cytological and biochemical features of PVM were also discussed and showed potentials to distinguish PVM from pediatric bacterial meningitis (PBM). The pathological, developmental, behavioral, and neuropsychological complications of PVM were also presented. All the previously utilized techniques for the etiological diagnosis of PVM which include virology, serology, biochemistry, and radiology, were presented and discussed to determine their efficiencies and limitations. Finally, molecular testing, mainly PCR, was introduced and showed 100% sensitivity rates.

Lycopene Scavenges Cellular ROS, Modulates Autophagy and Improves Survival through 7SK snRNA Interaction in Smooth Muscle Cells.

The chance of survival rate and autophagy of smooth muscle cells under calcium stress were drastically improved with a prolonged inclusion of Lycopene in the media. The results showed an improved viability from 41% to 69% and a reduction in overall autophagic bodies from 7% to 3%, which was well in agreement with the LC3II and III mRNA levels. However, the proliferation was slow compared to the controls. The fall in the major inflammatory marker TNF-α and improved antioxidant enzyme GPx were regarded as significant restoration markers of cell survival. The reactive oxygen species (ROS) were reduced from 8 fold to 3 fold post addition of lycopene for 24 h. Further, the docking studies revealed binding of lycopene molecules with 7SK snRNA at 7.6 kcal/mol docking energy with 300 ns stability under physiological conditions. Together, these results suggest that Lycopene administration during ischemic heart disease might improve the functions of the smooth muscle cells and 7SK snRNA might be involved in the binding of lycopene and its antioxidant protective effects.

Prevalence and Correlates of Vitamin D Deficiency in Children Aged Less than Two Years: A Cross-Sectional Study from Aseer Region, Southwestern Saudi Arabia.

Background: Vitamin D is an essential nutrient for bone growth, mineralization, and other metabolic processes in the human body. Hence, insufficiency or deficiency of this vitamin can have long-term effects, particularly for children. Objectives: The aims of this study were to determine the prevalence of vitamin D deficiency in children up to 2 years of age and investigate the independent predictors of vitamin D deficiency. Methodology: This cross-sectional study was conducted among 484 children aged up to two years who were admitted to the hospital for the treatment of any acute condition from January to November 2021. Serum 25(OH)D was used to determine the level of vitamin D. The serum 25(OH)D was categorized into 3 groups: Sufficiency (>30 ng/mL), insufficiency (20−30 ng/mL), and the deficiency (<20 ng/mL). Results: Overall, vitamin D deficiency was observed in 70.5% of the children, of whom 45.9% had insufficient levels, and one-fourth (24.6%) showed deficiency. The children aged 2−12 months (infants) were more likely to be vitamin deficient compared to children aged 12 months and above. The children who lived in urban areas had a threefold increased risk of vitamin D deficiency (aOR = 3.0, 95% CI 1.78−5.08). The children who were exposed to sunlight for less than 3 days per week experienced a higher risk of developing vitamin D deficiency (aOR = 4.17, 95% CI 2.04−10.88). Children who had received only breast milk were more than two times more likely to experience vitamin D deficiency (aOR = 2.42, 95% CI 1.12−5.23) compared to their counterparts. Conclusion: Our study reveals a high prevalence of vitamin D deficiency among children aged up to two years. Infants, urban dwellers, only breastfed, and exposure to sunlight for less than three days per week were identified to be the independent risk factors for vitamin D deficiency. The results of this work call for enhancing awareness to ensure adequate levels of vitamin D for better health of the children in this region of Saudi Arabia.

Clinical, laboratory, and chest radiographic characteristics of COVID-19 associated severe pediatric pneumonia. A retrospective study.

OBJECTIVES: To evaluate the demographics, clinical presentation, laboratory data, chest radiographs, and outcomes of pediatric patients with critical coronavirus disease 2019 (COVID-19). METHODS: This retrospective study included 34 children who were diagnosed with severe COVID-19 pneumonia between August 2020 and July 2021. Severe pneumonia was defined as fever, respiratory distress (tachypnea, chest retractions, and hypoxia [oxygen saturation <90% in room air]), and obvious infiltrations on chest radiography. RESULTS: Ages of the patients ranged from newborns to 12 years old, with a median of 24 months (interquartile range: 12-72 months). Preschool-aged children were the most common age group (44%). Levels of inflammatory markers (C-reactive protein, ferritin, and procalcitonin) were elevated in most patients. A total of 13 patients developed severe acute respiratory distress syndrome (ARDS), while 4 developed multiorgan failure. Despite receiving supportive therapy, 2 (5.9%) patients died due to severe septic shock and multiorgan failure. One deceased patient was born prematurely at 30 weeks, while the other had chronic granulomatous disease. CONCLUSION: This study described a single-center cohort of pediatric patients with severe COVID-19 pneumonia. In this cohort, children with cardiopulmonary comorbidities and ARDS had a high mortality and long-term morbidity, as observed in other pediatric studies.

Factors Affecting Glycemic Control among Saudi Children with Type 1 Diabetes Mellitus in Aseer Region, Southwestern Saudi Arabia.

Glycemic control in children with type 1 diabetes mellitus (T1DM) is affected by many factors that may be influenced by their lives and community. To identify the factors associated with glycemic control among children with T1DM in Aseer Region, southwestern Saudi Arabia, a cross-sectional interview study was conducted between 1 July and 30 September 2021, with a representative sample of Saudi children aged between 6 months and 15 years with T1DM or their caregivers visiting the diabetes center at Aseer Region. Newly diagnosed cases (<12 months) were excluded from the study. The study included 171 T1DM pediatric patients aged between 18 months and 15 years. The glycated hemoglobin (HbA1c) level ranged between 6.10% and 15.10% (mean HbA1c = 10.39% ± 1.86%). High HbA1c levels (≥7.5%) were observed in most patients (94.7%). Only two significant factors were found: (1) use of carbohydrate counting; 81.8% of children using carbohydrate counts had high HbA1c levels, compared to 96.6% of children not using carbohydrate counts (p = 0.017), and (2) duration of the disease; 91.5% of children with disease duration of ≤3 years had high levels of HbA1c, compared to 98.7% of children with disease duration exceeding 3 years (p = 0.035). Most children with T1DM in Aseer Region had poor glycemic control. Only two factors were associated with better glycemic control: shorter disease duration and use of carbohydrate counting. Therefore, advising diabetic patients to be on a carbohydrate counting program might improve DM control.

Perceptions of Parents towards COVID-19 Vaccination in Children, Aseer Region, Southwestern Saudi Arabia.

Vaccines are an important part of the COVID-19 pandemic response plan. This cross-sectional study aims to assess the attitude and perception levels of parents toward COVID-19 vaccines for children aged 0-18 years in the Aseer region of Saudi Arabia. Data were analyzed using SPSS version 16.0. Out of a total of 1463 parents, 30.6% assumed that COVID-19 vaccination may be more dangerous for children than adults. Nearly 36.5% parents don't have any concern about children's vaccination. About 12.8% of children have not received the vaccination, 55% of parents have some sort of hesitation and 32.2% of parents did not hesitate before vaccinating their children against COVID-19. Only 15.4% of parents expect that the COVID-19 vaccine affects their child's genes. About 23.4% parents strongly agreed and 35.1% agreed about the importance of getting their children vaccinated. About 22.1% of parents strongly agreed and 33.3% agreed regarding their willingness to get their children vaccinated to prevent Coronavirus disease. More than 80% of parents recommended rushing to receive the COVID-19 vaccine. Health professionals and policymakers should implement and support strategies to ensure children are vaccinated for COVID-19. They also need to educate parents and families regarding childhood vaccination.

HBD-2 variants and SARS-CoV-2: New insights into inter-individual susceptibility.

Background: A deep understanding of the causes of liability to SARS-CoV-2 is essential to develop new diagnostic tests and therapeutics against this serious virus in order to overcome this pandemic completely. In the light of the discovered role of antimicrobial peptides [such as human b-defensin-2 (hBD-2) and cathelicidin LL-37] in the defense against SARS-CoV-2, it became important to identify the damaging missense mutations in the genes of these molecules and study their role in the pathogenesis of COVID-19. Methods: We conducted a comprehensive analysis with multiple in silico approaches to identify the damaging missense SNPs for hBD-2 and LL-37; moreover, we applied docking methods and molecular dynamics analysis to study the impact of the filtered mutations. Results: The comprehensive analysis reveals the presence of three damaging SNPs in hBD-2; these SNPs were predicted to decrease the stability of hBD-2 with a damaging impact on hBD-2 structure as well. G51D and C53G mutations were located in highly conserved positions and were associated with differences in the secondary structures of hBD-2. Docking-coupled molecular dynamics simulation analysis revealed compromised binding affinity for hBD-2 SNPs towards the SARS-CoV-2 spike domain. Different protein-protein binding profiles for hBD-2 SNPs, in relation to their native form, were guided through residue-wise levels and differential adopted conformation/orientation. Conclusions: The presented model paves the way for identifying patients prone to COVID-19 in a way that would guide the personalization of both the diagnostic and management protocols for this serious disease.

Occupational Radon Assessment in Underground Storage Facilities in Saudi Arabia.

ABSTRACT: An occupational radon assessment was conducted at five underground storage facilities in the Kingdom of Saudi Arabia to evaluate the radon concentration and determine if remedial action is required to ameliorate conditions and ensure compliance with international guidance on acceptable radon levels in working environments. The assessment was carried out in four operational areas in the underground storage facilities routinely occupied or visited by workers. Initial radon concentrations were obtained using 293 passive CR-39 Nuclear Track Detector (NTD) radon dosimeters installed in the four operational areas for all the underground storage facilities. The detectors were left in place for 12 mo. As some of the radon measurements exceeded the International Atomic Energy Agency reference level of 1,000 Bq m-3 for radon in workplaces, a follow-up assessment was conducted using a real-time monitoring device in locations where high radon levels were observed. The measured radon concentrations in the four operational areas in three of the five underground storage facilities were below the reference level, and in the remaining two storage facilities, low ventilation rates in one operational area were identified as the principal cause of elevated radon concentrations. Notwithstanding, the potential radiation dose from radon exposure was determined to be well below the International Commission on Radiation Protection reference annual dose level of 10 mSv in all five underground storage facilities. Radon exposure to workers in all the underground storage facilities was found to be within the reference dose level for workplaces and does not pose an acute health risk.

Multi-system inflammatory syndrome in children during the coronavirus disease 2019 in Saudi Arabia: Clinical perspective from a case series.

ABSTRACT: Most of the reports about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children reported mild-to-moderate disease manifestations. However, recent reports explored a rare pediatric multisystem syndrome possibly associated with SARS-CoV-2 infection termed multisystem inflammatory syndrome in children (MIS-C).The study prospectively enrolled 5 patients with clinical and laboratory evidence of MIS-C associated with SARS-CoV-2 infection. They were admitted to the pediatric intensive care unit (PICU). Their clinical presentation, laboratory, and outcome were described.All patients shared similar clinical presentations such as persistent documented fever for more than 3 days, respiratory symptoms, gastrointestinal involvement, and increased inflammatory markers (CRP, ESR, and ferritin). Three patients had concurrent positive coronavirus disease 2019 (COVID-19) infection, and the other 2 patients had contact with suspected COVID-19 positive patients. They were all managed in the PICU and received intravenous immunoglobulin, systemic steroid, and hydroxychloroquine. The hospital stays ranged between 3 and 21 days. One patient died due to severe multiorgan failures and shock, and the other 4 patients were discharged with good conditions.Pediatric patients with SARS-CoV-2 are at risk for MIS-C. MIS-C has a spectrum of clinical and laboratory presentations, and the clinicians need to have a high index of suspicion for the diagnosis and should initiate its early treatment to avoid unfavorable outcomes. Long-term follow-up studies will be required to explore any sequelae of MIS-C, precisely the cardiovascular complications.

Knowledge, Attitudes, and Practices Regarding Brucellosis among Parents in Aseer Region, Southwestern Saudi Arabia.

This study aimed to investigate the knowledge, attitudes, and practices regarding brucellosis among parents in the Aseer region of southwestern Saudi Arabia in order to estimate the population sectors that are at high risk for accidental exposure to brucellosis. This was a cross-sectional survey conducted in 2018, including 311 participants representing various genders, ages, and levels of education. Bivariate analysis showed a significant association of good awareness of the disease with the male gender and higher education levels. Of the 311 participants, 90.0% had good knowledge, whereas 10.0% showed inadequate knowledge about brucellosis. Practices and attitudes regarding brucellosis were satisfactory as participants did not eat meat from their own animals (52.7%), did not practice slaughtering (71.4%), did not participate in the birth of animals (91.3%), were not exposed to abortion in animals (93.2%), and practiced burial of aborted animal fetuses (59.2%). The practice regarding brucellosis was unsatisfactory as 66.6% never wore gloves when dealing with animals. The study concluded that the majority of parents showed fair and positive knowledge, attitudes, and practices regarding brucellosis and found that gender and education were determinants of satisfactory awareness.

Distinctive clinical and laboratory features of COVID-19 and H1N1 influenza infections among hospitalized pediatric patients.

BACKGROUND: It had been documented in many studies that pediatric coronavirus disease 2019 (COVID-19) is characterized by low infectivity rates, low mortalities, and benign disease course. On the other hand, influenza type A viruses are recognized to cause severe and fatal infections in children populations worldwide. This study is aimed to compare the clinical and laboratory characteristics of COVID-19 and H1N1 influenza infections. METHODS: A retrospective study comprising 107 children hospitalized at Abha Maternity and Children Hospital, Southern region of Saudi Arabia, with laboratory-confirmed COVID-19 and H1N1 influenza infections was carried out. A complete follow-up for all patients from the hospital admission until discharge or death was made. The clinical data and laboratory parameters for these patients were collected from the medical records of the hospital. RESULTS: Out of the total enrolled patients, 73 (68.2%) were diagnosed with COVID-19, and 34 (31.8%) were diagnosed with H1N1 influenza. The median age is 12 months for COVID-19 patients and 36 months for influenza patients. A relatively higher number of patients with influenza had a fever and respiratory symptoms than COVID-19 patients. In contrast, gastrointestinal symptoms were observed in a higher number of COVID-19 patients than in influenza patients. A statistically significant increase in white cell counts is noted in COVID-19 but not in influenza patients (P < 0.05). There are no obvious variations in the mean period of duration of hospitalization between COVID-19 and influenza patients. However, the total intensive care unit length of stay was longer for influenza compared to COVID-19 patients. CONCLUSIONS: A considerable number of children infected with COVID-19 and H1N1 influenza were noted and reported in this study. There were no significant variations in the severity of the symptomatology and laboratory findings between the two groups of patients. Significant differences between these patients in some hospitalization factors and diagnosis upon admission also were not observed. However, more severe clinical manifestations and serious consequences were observed among pediatric patients hospitalized with influenza infections than among those with COVID-19.
