RESUMEN
BACKGROUND: Neonatal sepsis is a global concern with increasing morbidity and mortality. The burden of neonatal sepsis is highest in developing countries, especially in those lacking proper surveillance systems. The causative pathogens and their drug-resistance levels vary between countries with emergence of multidrug resistance organisms. Thus, accurate records on the recent trends of organisms causing neonatal sepsis will provide vital information for appropriate intervention. We aimed to investigate neonatal sepsis, identify its associated factors and causative pathogens and to assess the antibiotic susceptibility patterns in Sana'a city, Yemen. METHODS: A cross-sectional study was conducted on neonates admitted to intensive care units of six hospitals in Sana'a city, Yemen, in the period from January 15, to March 30, 2020. Natal and prenatal medical data were collected using well-structured questionnaire. Neonates were subjected to sepsis work-up including blood culture, complete blood count and C-reactive protein. Organisms were identified by Gram staining and analyzed by the VITEK II system for bacterial bio-typing and antibiotic susceptibility testing. FINDINGS: Of the 199-neonates with suspected neonatal sepsis, 154 (77.38%) had culture-proven sepsis. Early-onset neonatal sepsis (EOS) was higher (50.25%; 100/199) than late-onset neonatal sepsis (LOS) (27.13%; 54/199). Multivariable analysis identified vaginal delivery as an independent risk factor for neonatal sepsis p = 0.005. Majority of isolated bacteria (74.39%) were gram-negative with Burkholderia cepacia (39%) and Klebsiella oxytoca (13%) being the most common pathogens of EOS and LOS. The most common gram-positive pathogens were Staphylococcus haemolyticus (9.1%) and Staphylococcus epidermidis (7.1%). B. cepacia showed multidrug resistance except for cefepime. All Klebsiella species isolates (100%) and most Pantoea species (93%) were ESBL and carbapenemase positive. All Escherichia coli and Acinetobacter baumannii isolates were ESBL positive. A significant number of gram-positive bacteria showed resistance to vancomycin. CONCLUSION: The study findings show a high proportion of neonatal sepsis among neonates admitted to hospitals in Sana'a city with antibiotic-resistant B. cepacia being the single most common pathogen causing EOS and LOS. Findings also emphasize the emerging threat of multidrug-resistant bacteria in neonatal units and will help develop evidence-based management of neonatal sepsis in Yemen.

As a therapeutic approach, epigenetic modifiers have the potential to enhance the efficacy of chemotherapeutic agents. Protein arginine methyltransferase 5 (PRMT5), highly expressed in lung adenocarcinoma, was identified to be involved in tumorigenesis. In the current study, we examined the potential antineoplastic activity of PRMT5 inhibitor, arginine methyltransferase inhibitor 1 (AMI-1), and cisplatin on lung adenocarcinoma. Bioinformatic analyses identified apoptosis, DNA damage, and cell cycle progression as the main PRMT5-associated functional pathways, and survival analysis linked the increased PRMT5 gene expression to worse overall survival in lung adenocarcinoma. Combined AMI-1 and cisplatin treatment significantly reduced cell viability and induced apoptosis. Cell cycle arrest in A549 and DMS 53 cells was evident after AMI-1, and was reinforced after combination treatment. Western blot analysis showed a reduction in demethylation histone 4, a PRMT5- downstream target, after treatment with AMI-1 alone or in combination with cisplatin. While the combination approach tackled lung cancer cell survival, it exhibited cytoprotective abilities on HBEpC (normal epithelial cells). The survival of normal bronchial epithelial cells was not affected by using AMI-1. This study highlights evidence of novel selective antitumor activity of AMI-1 in combination with cisplatin in lung adenocarcinoma cells.

INTRODUCTION: Interruptions are common in the emergency department and contribute to catastrophic errors. Care priorities and acuity levels are assigned during triage, meaning that mistakes and omissions during the triage process could have detrimental effects on patients. The purpose of this project was to assess the feasibility of investigating the impact of interruptions on triage and the decision-making process in a simulated setting. METHODS: A 2-phase, sequential exploratory mixed method design was used. Nine nurses from 3 emergency departments in a Midwest area participated. A short demographic questionnaire was used to collect information about the nurses' education and experience. The Emergency Severity Index (ESI) was used for triage categorization. Each participant completed 2 scenarios (one interrupted and one uninterrupted). After completion of the scenarios, video-simulated recall interviews were used to assess the simulation experience and the impact that interruptions had on the triage decision-making process. RESULTS: Triage time had a mean of 10 minutes and ranged between 4.34 minutes and 13.45 minutes. However, triage was significantly longer during the interrupted scenarios. Seventy-seven percent of the acuity assessments (ESI) were correct. Of the 18 scenarios, 3 uninterrupted scenarios had incorrect ESI scores, and one interrupted scenario had a missing acuity score. DISCUSSION: This study provides the basis for future work that looks at how nurses successfully manage interruptions and tests interventions to assist triage nurses in managing or reducing interruptions during this important patient assessment process.

BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency, the most common genetic enzymopathy worldwide, is associated with an acute haemolytic anaemia in individuals exposed to primaquine. The present study aimed to determine G6PD deficiency among Yemeni children in malaria-endemic areas as well as to assess the performance of the CareStart™ G6PD rapid diagnostic test (RDT) for its detection. METHODS: A cross-sectional study recruiting 400 children from two rural districts in Hodeidah governorate was conducted. Socio-demographic data and blood samples were collected and G6PD deficiency was qualitatively detected in fresh blood in the field using the CareStart™ G6PD RDT, while the enzymatic assay was used to quantitatively measure enzyme activity. Performance of the CareStart™ G6PD RDT was assessed by calculating its sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) against the reference enzymatic assay. RESULTS: The ranges of enzyme activity were 0.14-18.45 and 0.21-15.94 units/g haemoglobin (U/gHb) for males and females, respectively. However, adjusted male median G6PD activity was 5.0 U/gHb. Considering the adjusted male median as representing 100 % normal enzyme activity, the prevalence rates of G6PD deficiency were 12.0 and 2.3 % at the cut-off activities of ≤60 and ≤10 %, respectively. Multivariable analysis showed that gender, district of residence and consanguinity between parents were independent risk factors for G6PD deficiency at the cut-off activity of ≤30 % of normal. The CareStart™ G6PD RDT showed 100 % sensitivity and NPV for detecting G6PD deficiency at the cut-off activities of ≤10 and ≤20 % of normal activity compared to the reference enzymatic method. However, it showed specificity levels of 90.0 and 95.4 % as well as positive/deficient predictive values (PPVs) of 18.0 and 66.0 % at the cut-off activities of ≤10 and ≤20 %, respectively, compared to the reference method. CONCLUSIONS: G6PD deficiency with enzyme activity of ≤60 % of normal is prevalent among 12.0 % of children residing in malaria-endemic areas of Hodeidah governorate, with 2.3 % having severe G6PD deficiency. Gender, district of residence and consanguinity between parents are significant independent predictors of G6PD deficiency at the cut-off activity of ≤30 % of normal among children in malaria-endemic areas of Hodeidah. The CareStart™ G6PD RDT proved reliable as a point-of-care test to screen for severely G6PD-deficient patients, with 100 % sensitivity and NPV, and it can be used for making clinical decisions prior to the administration of primaquine in malaria elimination strategies.

This retrospective study aims to evaluate the safety of everolimus when used as part of the immunosuppression regimen in patients who underwent liver transplant from 2009 to 2019 at a tertiary liver transplant center. Patients were divided into two groups: those who received everolimus as part of the post-transplant regimen and those who did not. The primary safety outcome measured was the development of new pulmonary complications that had been associated with everolimus use in prior studies. Lung function was determined by pulmonary function tests if available or CT scans of the chest. Secondary outcomes measured included everolimus discontinuation rates and survival rates. During the study period, 450 patients underwent liver transplant; 35% of patients received everolimus (n=156) and 65% of patients did not receive everolimus (n=292). Primary safety outcome of pulmonary complications was seen in 3.9% of patients who received everolimus (n=6) and 6.3% of the control group patients who did not receive everolimus (n=19). The association between everolimus use and new pulmonary complications was not significant with a chi-square statistic of 1.33 (p=0.249). Overall, 51.3% of patients who received everolimus during their post-transplant course discontinued the medication (n=80). Everolimus is safe from a pulmonary toxicity standpoint in liver transplant immunosuppression regimens as there was no significant difference found in pulmonary complications between patients who received the medication and those who did not.
RESUMEN
Aloe perryi has been studied and possesses several activities, including antibacterial, antiparasitic, and anticancer properties. In this study, A. perryi was used as a reducing agent of silver ions into silver nanoparticles. Aloe perryi-silver nanoparticles (APS-NPs) were characterized and evaluated using characterization techniques. However, the antioxidative, antibacterial, and anticancer assays were studied to evaluate the pharmacological activities of APS-NPs. APS-NPs were developed and changed to dark brown and the maximum absorption was 442 nm. SEM (5-583 nm), TEM (4-110 nm), XRD (21.84 nm), and zeta potential analysis (63.39 nm) revealed that the APS-NPs were nano-sized, and the APS-NPs had a cubic crystalline structure, according to the XRD results. FTIR analysis suggested that functional groups of A. perryi metabolites were involved in forming APS-NPs. The zeta potential indicated that the APS-NPs were negatively charged (-32 mV), suggesting good stability. APS-NPs showed significant antioxidative stress activity by reducing DPPH-free radicles in a dose-dependent manner. APS-NPs-induced antibacterial effect against Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and Acinetobacter baumannii (A. baumannii). APS-NPs reduced the cell viability and cell migration of the human colon tumor cell line (HCT 116) compared with controls, indicating that APS-NPs could play a role in reducing metastasis and inducing cell apoptosis against colon cancer. In conclusion, the nanoparticle synthesis from A. perryi extract demonstrated excellent antioxidant, antibacterial, and anticancer activities, thus suggesting that our APS-NPs have the potential to be used as antioxidative and antibacterial in food and pharmaceutical industries.
RESUMEN
BACKGROUND: The prevalence of overweight and obesity among adolescents in Saudi Arabia has been progressively increasing. Obesity is associated with an increased risk of various morbidities and mortality. Identifying the factors that contribute to obesity in this age group is crucial for implementing targeted prevention measures. AIM: The aim of this study was to identify risk factors for overweight and obesity among adolescents aged nine to 17 years residing in Tabuk City, Saudi Arabia. METHODS: A case-control study was conducted during the 2021-2022 academic year at Alabnaa Schools in Tabuk City, Saudi Arabia. The study included overweight/obese individuals (cases, n = 125) and normal-weight individuals (controls, n = 201) who were selected based on their body mass index and classified according to the World Health Organization's reference for defining overweight and obesity in individuals aged five to 19 years. Data were collected from both groups using a self-administered questionnaire. RESULTS: The study analyzed 125 overweight/obese students and 201 normal-weight students who were matched for sex and age (p > 0.05). Logistic regression analysis identified several risk factors for overweight or obesity among adolescents. A family history of obesity was found to be associated with a 5.735 times increased likelihood of obesity (95% CI: 3.318-9.912, p < 0.001). Another significant contributing risk factor for obesity was frequent consumption of four or more meals per day (adjusted odds ratio: 3.091, 95% CI: 1.094-8.736, p = 0.033). Students who used electronic devices for more than five hours were 2.422 times more likely to exhibit obesity (p = 0.006). CONCLUSIONS: Certain factors may increase the risk of overweight or obesity in adolescents aged nine to 17 years. These factors include frequent eating, prolonged use of electronic devices, family history of obesity, and the misconception that obesity is not an illness. Tailored school health programs are needed to improve students' healthy lifestyles and eating behaviors, minimize sedentary entertainment and use of electronic devices, and engage children in physical activity.
RESUMEN
WPW (Wolff-Parkinson-White) syndrome is a congenital heart condition characterized by an abnormal accessory electrical pathway in the heart that can cause rapid heartbeat (supraventricular tachycardia). Radiofrequency ablation is considered the first-line treatment, it can be curative in almost 95% of patients. Sometimes ablation therapy can fail when the pathway is close to the epicardium. We hereby report a case of a patient with a left lateral accessory pathway. Several attempts of ablation from the endocardium targeting a clear pathway potential failed. Subsequently, the pathway was safely and successfully ablated from within the distal coronary sinus.
RESUMEN
Inflammatory bowel diseases (IBD), including ulcerative colitis, are chronic autoimmune conditions characterized by inflammation of the digestive system. The exact cause of IBD is unknown, but they often start during adolescence or early adulthood with symptoms such as urgency, rectal bleeding, diarrhea, abdominal pain and tenesmus. Primary sclerosing cholangitis and autoimmune hepatitis are recognized as co-occurring conditions associated with ulcerative colitis. However, the combination of ulcerative colitis, primary sclerosing cholangitis, liver cirrhosis, and celiac disease occurring concurrently has only been reported once before in a female patient. Here, we present the exceptional case of a Syrian adult male with all four of these conditions. This highlights the importance of screening for both celiac disease and cirrhosis in patients with ulcerative colitis and primary sclerosing cholangitis together, despite this combination of comorbidities is rare.
RESUMEN
Acute care nurse practitioners (ACNPs) require special training and educational preparation to meet their role expectations. Using high fidelity simulation with debriefing modalities is considered one of the innovative learning strategies in graduate nursing. No studies have investigated debriefing modalities in nurse practitioner programs specially ACNPs leadership skills. The purpose of this study was to examine the difference in students' knowledge, code team leader skills and self-efficacy using two debriefing modalities. A two group, pretest-posttest quasi-experimental design was used. Students were divided into video-assisted debriefing group vs. verbal debriefing following a simulation scenario of managing emergency codes. There were no significant differences between the two groups in knowledge acquisition/retention, leadership skills, and self-efficacy, but there was a significant difference in self-efficacy in both groups between two-time points. There was a general improvement in teams' performance. Students preferred verbal debriefing over video-assisted debriefing. The debriefing session plays an important role in graduate nursing education. Acute care nurse practitioners are lacking a formal leadership training to meet their advanced role. Nurse Educators, and simulation/debriefing leaders may benefit from our study results to develop a structured, formal curriculum and educational instruction focusing on acute care nurse practitioners' role change especially leading a resuscitation team.

OBJECTIVE: Cricopharyngeal myotomy as an independent procedure has been performed on fourteen patients with a variety of neuromuscular disorders, suffering from neurogenic oropharyngeal dysphagia in the interval between 1994-1997. All of them were referred from a neurophysician or physiatrist after failure of improvement by medical treatment. METHODS: The selection of patients for operation was based mainly on clinical evaluation and simple exclusion criteria without manometric studies. RESULTS: There was dramatic improvement in twelve, with recurrent laryngeal nerve palsy and temporary pharyngeal fistula in two patients. No mortality was recorded. CONCLUSION: We conclude that cricopharyngeal myotomy is a simple, safe and effective procedure with acceptable morbidity. It should be considered as a rehabiliation procedure for patients with dysphagia due to various neurologic disorders based on simple, clinical exclusion criteria without the need for the tedious, time consuming and expensive manometric studies.
RESUMEN
Copper was determined in the blood of breeding camels, camel calves and racing camels to evaluate copper status in these animals in UAE. Low blood copper concentrations were reported in newly born camel calves (100%) and calves 2-4 months old (68%), breeding camels at early (55.6%) and at mid lactation (48%) and at late pregnancy (69%). This is attributed to the low copper and high sulfate in the Rhodes grass which is the only diet offered to the breeding camels. On the other hand only 9.7% of racing camels showed low copper levels. This is because copper is routinely offered to racing camels when their blood copper is low. Cupric oxide needle capsules orally administered at the rate of 8 g per adult camel was effective in elevating blood copper from 7.083 micromol/L at day zero to 10.074 micromol/L at day 28 after dosing.
