National Healthcare-Associated Infections Report 2022 - Saudi Arabia.

BACKGROUND: Surveillance data are very essential for the effective use of available resources, the prioritization of infection control practices, and setting goals for intervention. The aim was to present the current rates of healthcare-associated infections (HAIs) and device utilization ratios (DUR) among the Saudi Ministry of health (MOH) hospitals. METHODS: MOH analyzed the surveillance data collected from 106 MOH hospitals enrolled in the health electronic surveillance network (HESN) between January 2022 and December 2022. The surveillance methodology was similar to the methods of the US National Healthcare Safety Network (NHSN) and the Gulf Cooperation Council (GCC) center for infection control. RESULTS: More than one million device-days of surveillance were analyzed. The rate of central line associated bloodstream infection (CLABSI) was 2.57 per 1000 central lines days. The rate of catheter-associated urinary tract infection (CAUTI) was 1.08 per 1000 urinary catheter days. The rate of ventilator-associated events (VAE) was 4.21 per 1000 ventilator days. The average rate of pediatric/neonatal ventilator-associated pneumonia (VAP) was 1.53 per 1000 ventilator days. The average DURs were 0.33 for central line, 0.61 for urinary catheter, 0.44 for ventilator in adult patients, and 0.26 in ventilator in pediatric/neonatal patients. In 238632 months of surveillance, the rate of dialysis events (DE) was 0.97 per 100 patient-months. In 86324 surgeries monitored, the rate of surgical site infection (SSI) was 0.87 per 100 surgeries surveyed. CONCLUSIONS: The current report can serve as a national benchmark for MOH hospitals and a regional benchmark for similar hospitals in the region.

Treatment Outcomes in COVID-19 patients with comorbidities in Kaduna state, NorthwesternNigeria

Background: Severe COVID-19 disease has been reported among people with underlying conditions such as diabetes, chronic respiratory diseases, cancer, obesity, and cardiovascular disease. This study determined the outcomes of COVID-19 among patients with comorbidities in Kaduna state, where we have the highest incidence in northern Nigeria.Methods: This study was a retrospective, descriptive cross-sectional review of the clinical records involving all age groups of 902 COVID-19 patients admitted at the four isolation centers of the Kaduna State Infectious Disease Control Centre (IDCC) between March 27th2020 to December 31st2021. Data was analyzed with SPSS version 25 and STATA SE 12 with p <0.05.Results: Out of the 902 cases, 245(27.2%) had comorbidities, hypertension 206(22.8%) was the most recorded comorbidity, others were diabetes 77(8.5%), asthma 7 (0.78%), HIV 7(0.78%), sickle cell anemia 7 (0.78%) and PTB 3 (0.33%). Patients with comorbidities had prolonged mean duration of symptoms 8.36±3.5 days, compared to 7.2±2.7 days in those without comorbidities (p=0.001).Multivariate logistic regression analysis further shows that the odds for clinical recovery from the COVID-19 disease was significantly lower for patient with hypertension (AOR=0.13, 95%CI=0.06-0.27, p = <0.01), diabetic (AOR=0.20, 95% CI=0.10-0.40, p<0.01) and HIV comorbidities (AOR=0.1, 95%CI=0.01-0.98, p=0.05) compared to those without comorbiditiesConclusion: Hypertension and diabetes were the major comorbidities in this study. Most patients with comorbidities had severe presentations and fatal poorer outcome. There is a need for sustained public health education targeted at patients with chronic diseases to be screened and treated early for COVID 19 Disease

Unified scenario for the morphology of crack paths in two-dimensional disordered solids.

A combined experimental and numerical investigation of the roughness of intergranular cracks in two-dimensional disordered solids is presented. We focus on brittle materials for which the characteristic length scale of damage is much smaller than the grain size. Surprisingly, brittle cracks do not follow a persistent path with a roughness exponent ζ≈0.6-0.7 as reported for a large range of materials. Instead, we show that they exhibit monoaffine scaling properties characterized by a roughness exponent ζ=0.50±0.05, which we explain theoretically from linear elastic fracture mechanics. Our findings support the description of the roughening process in two-dimensional brittle disordered solids by a random walk. Furthermore, they shed light on the failure mechanism at the origin of the persistent behavior with ζ≈0.6-0.7 observed for fractures in other materials, suggesting a unified scenario for the geometry of crack paths in two-dimensional disordered solids.

Effectiveness of the critical congenital heart disease screening program for early diagnosis of cardiac abnormalities in newborn infants.

OBJECTIVES: To evaluate the effectiveness of critical congenital heart disease (CCHD) screening program for early diagnosis of cardiac anomalies in newborn infants.  Methods: This is a hospital-based prospective cross-sectional study conducted in the Pediatric and Neonatology Department, King Fahad Hospital at  Albaha, Saudi Arabia, between February 2016 and February 2017. Results: We screened 2961 (95.4%) of 3103 patients in a nursery unit; 142 (4.6%) patients were not screened. The test was positive in 114 (3.9%) patients and negative in 2847 (96.1%). There were 94 (3.2%) false positives and 20 (0.7%) true positives. Critical cardiac defects were diagnosed in 7 (0.2%) patients of all screened infants, and severe pulmonary hypertension was diagnosed in 13 (0.4%) patients. True negative results were found in 2841(96%) patients, and no cardiac defect was diagnosed, whereas false negative results were seen in 6 (0.2%) patients diagnosed with ventricular septal defect. The sensitivity was 77%, and the specificity was very high at 97%, with a positive predictive value of 18%, and a negative predictive value of 99.8% (95% confidence interval 13.78-19.18, p=0.0001). Conclusion: Pulse oximetry was found to be easy, safe, sensitive, and highly specific for diagnosis of CCHD.
