Abstract
The antigen rapid diagnostic test (Ag-RDT) is an assay kit for detecting the SARS-COV-2 nucleocapsid proteins, based on the colloidal gold method.Accurate diagnosis has an important role in limiting the transmission of SARS-COV-2, and also helps patients to receive earlier treatment .The object of this study was to perform the clinical evaluation of a novel Ag-RDTs with samples collected from two different swabs.DEEPBLUE®COVID-19 antigen detection kit used for the examination of the subjects in the experiment.For antigen testing on samples collected with nasal swabs, sensitivity was 91.7 % (95 % CI 83.6-96.6 %) and specificity was 100 %(95 %CI 98.1-100 %).For nasopharyngeal swabs, the sensitivity was 96.8 % (95 % CI 93.6-98.7 %) and the specificity was 100 % (95 % CI 98.2-100 %).Fisher Precision test showed a significant correlation between nasopharyngeal swab Ag-RDTs and nasal swab Ag-RDTs and RT-qPCR test (p-value <0.001).The results showed that the patients use the kit for testing were comparable to the RT-qPCR.

Abstract
The Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-CoV-2) pandemic has transformed our appreciation of healthcare awareness worldwide. The amount of related data accumulated during this time has surpassed any other outbreak of a viral pathogen. Healthcare awareness is related to one of the nine pillars of the “World health organization (WHO) operational planning guidelines to support country preparedness and response”. This review is structured around the awareness/knowledge, attitudes, and practices (KAP)-related publications in Saudi Arabia up to date to understand the impact of COVID-19 on these domains. The excellent communication effort response from governments, international, and individuals to keep the public informed about the outbreak is highlighted. Unraveling such impacts on the Saudi communities, including healthcare workers (HCWs)/professionals (HCPs), students, patients with different diseases, and non-professional individuals, is essential in containing the outbreak and planning preventive measures in case of future outbreaks.

Dental Care and Education Facing Highly Transmissible SARS-CoV-2 Variants: Prospective Biosafety Setting: Prospective, Single-Arm, Single-Center Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:7693. [PMID: 35805347 PMCID: PMC9266032 DOI: 10.3390/ijerph19137693] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 06/19/2022] [Accepted: 06/21/2022] [Indexed: 12/19/2022]
Abstract
With the arrival of the highly transmissible Omicron variants (BA.4 and BA.5), dentistry faces another seasonal challenge to preserve the biosafety of dental care and education. With the aim of protecting patients, students, teachers and healthcare professionals, this paper introduces a prospective sustainable biosafety setting for everyday dental care and education. The setting developed by dental clinicians, epidemiologists, and teachers of dentistry consists of a combination of modern technologies focused on the air-borne part of the viral pathway. The introduced biosafety setting has been clinically evaluated after 18 months of application in the real clinical environment. The protocol has three fundamental pillars: (1) UVC air disinfection; (2) air saturation with certified virucidal essences with nebulizing diffusers; (3) complementary solutions including telehealth and 3D printing. A pseudonymous online smart form was used as the evaluation method. The protocol operates on the premise that everybody is a hypothetical asymptomatic carrier. The results of a clinical evaluation of 115 patient feedbacks imply that no virus transmission from patient to patient or from doctor to nurse was observed or reported using this protocol, and vice versa, although nine patients retrospectively admitted that the clinic visit is likely to be infectious. Despite these promising results, a larger clinical sample and exposition to the current mutated strains are needed for reliable conclusions about protocol virucidal efficiency in current dental environments.

Diagnostics (Basel) 2022; 12:diagnostics12040847. [PMID: 35453895 PMCID: PMC9030639 DOI: 10.3390/diagnostics12040847] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 11/16/2022] Open
Abstract
Accurate diagnosis to limit the spread of SARS-CoV-2 is crucial for the clinical management of this lethal infection. Recently, many low-cost and easy-to-use rapid test kits (RTK) have been developed in many countries for the massive screening of SARS-CoV-2. Thus, evaluating the accuracy and reliability of an RTK is critical. The current study was conducted on 157 individuals to evaluate the performance accuracy of rapid SARS-CoV-2 antigen detection kits using different clinical samples compared with qRT-PCR results. Nasopharyngeal swabs were collected from patients for qRT-PCR and RTK tests, and then buccal and nasal, and nasal swabs were collected for RTK tests separately. The nasal and buccal swabs showed high sensitivity (98%) and specificity (100%) compared with the qRT-PCR results. Meanwhile, for nasal, the sensitivity was 96% with 98% specificity, and nasopharyngeal swabs showed 98% sensitivity and 94% specificity. Fisher’s exact test revealed statistical significance (p < 0.05) between nasopharyngeal, nasal and buccal, and nasal swabs compared with qRT-PCR results. The study concludes that different clinical samples used for the rapid diagnosis of SARS-CoV-2 showed high sensitivities and specificities compared with qRT-PCR. The RTKs using nasal and buccal, nasopharyngeal, and nasal swabs are valuable tools for the early detection of SARS-CoV-2, especially when molecular detections are available with limited access and a high infectivity rate, when the timely detection of virus cases is urgently needed. These types of clinical samples are effective to be used by RTKs for surveillance among community and healthcare workers.
