Are saudi healthcare students aware of COVID-19, and do they behave safely during viral outbreaks?

AIMS: The purpose of this study is to understand healthcare students' knowledge of COVID-19 and the precautionary behaviors they practiced in Saudi Arabia during the MERS-CoV2 outbreak. SUBJECTS AND METHODS: This cross-sectional study utilized an online questionnaire consisting of 29 items and three sections. The first section collected demographic information, including age, gender, location, and level of education. The second section assessed their knowledge of clinical characteristics, treatments, and disease prevention. The third section addressed the students' behaviors. RESULTS: Respondents included 223 students, of which 37.2% were males and 62.8% were females. The largest group of respondents included medical students (44.8%), followed by dental students (41.3%). Overall, students demonstrated a thorough knowledge of disease transmission, diagnosis, prevention, and treatment of COVID-19. However, some of the respondents could not identify the full name of the disease, Coronavirus Disease 2019 (64.6%), or provide a current estimate of the number of cases diagnosed globally (49.8%). Additionally, most of the survey respondents (93.3%) reported that they had followed social distancing guidelines issued by the Ministry of Health. CONCLUSION: While most health students were knowledgeable about most aspects of COVID-19, others did not follow universal precautions during the outbreak, which identifies better incorporation of such information in students' academic programs.

A contemporary look at COVID-19 medications: available and potentially effective drugs.

OBJECTIVE: There have been significant changes to the management of COVID-19 in recent months, including protocols and guidelines designed to prevent, diagnose, and treat the Novel Coronavirus (COVID-19). Several management options have been suggested and have since gained popularity, though we expect additional modifications to be made, as well as more new cases in the coming months, given a lack of definitive treatment and well-controlled experiments. This review highlights the available and potential treatments, along with the challenges associated with each. MATERIALS AND METHODS: We conducted a comprehensive overview of all peer-reviewed studies, editorial comments, and letters to the editor based on a search in PubMed, Google Scholar, Web of Science, and Scopus. The following terms were used: "COVID-19," "SARS-CoV-2," "drug," "treatment," "medication," and "management." All searches were done between March and May 20, 2020. RESULTS: There are several potential medications available for COVID-19, such as Interferon α (IFN-α), Teicoplanin, Ribavirin, Galidesivir, Lopinavir/Ritonavir, Chloroquine phosphate, Arbidol, Velpatasvir, Favipiravir, Ledipasvir, Remdesivir, Sofosbuvir, Darunavir, Qingfei Paidu Decoction (QPD), and Imatinib. However, we do not have a definitive and specific treatment yet. CONCLUSIONS: We are expecting to have more cases in the coming weeks/months. Therefore, further research is needed to characterize the disease behavior, to find the absolute drug, and to refine the treatment.

The prevalence and severity of dental caries in Chad: a pilot study.

OBJECTIVE: This study was undertaken to determine the prevalence and severity of dental caries among a cross section of a sample from different locations in Chad as part of a general assessment of their oral health status. METHODS: A cross-sectional descriptive survey of a nationwide sample included volunteers, 10 years or older, for a total of 1,011 participants. The survey consisted of a brief interview followed by a 1-2 minute oral examination of each subject. RESULTS: The mean age of the participants was 29.61 ±12.59 years and the total mean value for Decayed/Missing/Filled Teeth (DMFT)=1.96 ±1.78. Females had a higher mean DMFT (2.72 ±1.88); decayed (2.82 ±1.07); missing teeth (1.81 ±1.14) than males (1.61 ±1.60): decayed (2.11 ±1.09); missing (1.45 ±0.89, respectively; all p<0.001). The older group (>30 years) had higher DMFT (2.79 ±1.93) than the younger group (d"30 years; p<0.001). Urban area showed lower DMFT (1.81 ±1.68) than rural areas (2.31 ±1.95). CONCLUSION: In this study, the prevalence of dental caries is very low which is similar to the most of the African Saharan and sub-Saharan countries. However, there is need to establish caries control programs to prevent tooth decay in the future and help people maintain lifelong dental health.

The oral health status and the treatment needs in Chad: a pilot study.

AIMS AND OBJECTIVES: This study was designed to evaluate dental conditions, factors contributing to these conditions, and treatment needs among a population from different places in Chad, as part of a general assessment of their oral health. PATIENTS AND METHODS: A cross-sectional nationwide survey was conducted with 1,011 participants. The survey consisted of a brief health interview (conducted by dental students and public health specialists) followed by a 1-2 minutes oral examination (conducted by dental students and dentists). RESULTS: Sixty four per cent of the subjects had experienced dental pain, 66.7% had decayed teeth, and 56.6% had gum diseases. Dental pain was found to be distributed according to age, gender and locations (p<0.001). Only 25% of the participants had ever visited a dentist. Males were show to engage in more tobacco use than females (19.2% vs. 0.3%), while females were more likely to have visited a dentist than males (30.8% vs. 22.8%). Brushing of teeth occurred more often in urban than in rural locations (p<0.001), while date, sugar cane and cola nut intake were statistically significant in the older generation compared to the younger subjects (p<0.001). CONCLUSION: There was a significant need for dental treatment and care in the sample population. In addition, the availability of sugar, combined with poor knowledge, utilisation of preventive and restorative oral health care services have been contributed to have several dental conditions.
