Additionally, an age-matched control group of 20 patients aged 18–43 years (32.2±5.1 years) was enrolled in the study for comparison purposes. An Ocular Surface Disease Index dry-eye questionnaire was completed, followed by a test to determine the tear-evaporation rate using the VapoMeter. The test was performed three times per subject by the same examiner. Two readings were obtained each time.Results: Significant differences (P<0.05) were found between mean Ocular Surface Disease Index and tear-evaporation-rate scores within the study and control groups. The average tear-evaporation rate was much higher in the study group (median 41.2 [IQR 41.4] g/m2·h) than the control group (15.7 [13.7] g/m2·h). Moreover, the average Ocular Surface Disease Index score for thyroid-gland patients was much higher (15.6 [23.4]) compared to the control group (5.5 [7.50]).Conclusion: The tear-evaporation rate in thyroid-gland patients was found to be much higher than normal-eye subjects.

Vaccinations, testing and tracing have been proven to provide strong protection against severe illness and death. Older adults are amongst the groups with an increased risk of severe illness. This study aimed to explore the willingness and hesitancy of the elderly population in the Kingdom of Saudi Arabia to test and vaccinate against COVID-19.Methods: This cross-sectional study targeted participants aged 65 years and above. The questionnaire included both sociodemographic variables, and variables related to willingness and hesitancy to vaccinate and test for COVID-19 that were mainly based on existing literature. Bivariate analyses were performed to test for associations. Significance was set at the 0.05 level.Results: The total sample of respondents was 502. The results show that 52.4% were not aware of a previous infection. Participants aged above 70 years and females were found to be more aware of a previous infection (51.6% and 53.1% respectively) (P < 0.05). Also, 54.7% felt it necessary to test against COVID-19, and among those, 70.8% believed that testing would contain and control the spread. The results also show that 3.2% were not vaccinated to date, compared to 95.41% who had the complete dose as well as the recommended booster dose for elderlies. Age, sex and level of education were significantly associated with vaccine uptake, where participants aged between 65 and 70 years, males and high levels of education were associated with a complete vaccine uptake.Discussion: The current findings add to the epidemiological evidence and show that the social network theory within the context of health may have played a role in self-awareness of previous infections. Also, social factors should be incorporated in public health interventions and public health campaigns targeting the elderly are still needed especially with the continued discovery of variants of interests.Keywords: COVID-19, public health, health promotion, prevention, elderl

β-Lactamase Production in Key Gram-Negative Pathogen Isolates from the Arabian Peninsula

Infections due to Gram-negative bacilli (GNB) are a leading cause of morbidity and mortality worldwide. The extent of antibiotic resistance in GNB in countries of the Gulf Cooperation Council (GCC), namely, Saudi Arabia, United Arab Emirates, Kuwait, Qatar, Oman, and Bahrain, has not been previously reviewed. These countries share a high prevalence of extended-spectrum-β-lactamase (ESBL)- and carbapenemase-producing GNB, most of which are associated with nosocomial infections. Well-known and widespread β-lactamases genes (such as those for CTX-M-15, OXA-48, and NDM-1) have found their way into isolates from the GCCstates. However, less common and unique enzymes have also been identified. These include PER-7, GES-11, and PME-1. Several potential risk factors unique to the GCC states may have contributed to the emergence and spread of β-lactamases, including the unnecessary use of antibiotics and the large population of migrant workers, particularly from the Indian subcontinent. It is clear that active surveillance of antimicrobial resistance in the GCC states is urgently needed to address regional interventions that can contain the antimicrobial resistance issue
