Awareness and knowledge of glaucoma among visitors of main public hospitals in Damascus, Syria: a cross-sectional study.

BACKGROUND: The main way to prevent blindness from Glaucoma is by early detection and diagnosis; and to do so the awareness must be raised among people where Glaucoma is defined as an acquired chronic optic neuropathy characterized by optic disk cupping and visual field loss. Lack of knowledge about this disease is one of the most important reasons that made it develop to advanced stages. Based on that, we conducted scientific research to assess peoples' awareness and knowledge about Glaucoma. After reviewing the literature, it was found that this study is the first in Syria. METHODS: We conducted a cross-sectional study in May 2022. The study included participants, who are above 20 years old, from visitors of Al-Mouwasat University Hospital in Damascus, Syria. During one week, Data was gathered according to the questionnaire, which was presented through face-to-face interviews with participants. We have allocated one point (1) to each question. Three levels of knowledge were adopted, namely; weak level from (0) to (3), average level from (4) to (7) and good level from (8) to (11). Associations between participants' demographic and other details were tested using Chi-square test and other tests, and a p-value of < 0.05 was considered significant. RESULTS: A total of 500 participants were interviewed. For awareness of Glaucoma, 33.6% of the participants (n = 168) had heard of Glaucoma, and 66.4% hadn't (n = 332). Mean test results for the knowledge of Glaucoma was 1.62 out of 11, and only 8% of participants (n = 40) had a good knowledge of Glaucoma. Education Level, governorate, and department of hospital that the patient came for significantly affected the knowledge of Glaucoma. Moreover, hospital, Ophthalmologists' Clinics, and health staff (M = 5.45) were the better Resource for information than family, relatives, and friends (M = 3.16). Finally, social media and the Internet group had the lowest mean test results (M = 1.23). These test results were significant, with a p-value < 0.001. CONCLUSION: The percentage of knowledge and awareness was significantly low. Organized community awareness methods must disseminate more ability to increase the general public's understanding to avoid injury and late diagnosis of Glaucoma.

Identification and characterisation of mosquitoes from different locations in Qatar in 2017-2019.

Mosquito-borne infections have considerable consequences for public health. The mere presence of a single case of vector-borne disease (VBD) introduces a risk to the local community particularly when associated with the compatible vector, host, and suitable environmental factors. Presently, there is no well-established vector control and surveillance programme in Qatar; therefore, the likelihood of VBDs spreading is undetermined. As a result, there is a pressing need to address this gap and enable successful management of VBDs. This study presents the results of three consecutive field surveys conducted between 2017 and 2019 with the aim of defining the types and distribution of mosquitoes that are of public health importance in Qatar. The results of the adult mosquito trappings show that the southern house mosquito Culex quinquefasciatus is the most widespread and abundant mosquito species, followed by Cx. perexiguus, both species representing a risk of West Nile virus transmission. All sampling methods show that the malaria vector Anopheles stephensi is widespread including in urbanised areas, suggesting a risk of local malaria transmission. The wetland mosquito Aedes caspius is also widespread, representing a risk of Rift Valley fever virus transmission. The dengue vector Ae. aegypti was not detected and can be considered neither widespread nor abundant, suggesting a minimal risk for local transmission of dengue, chikungunya and Zika viruses. Interestingly, the study detected Culiseta longiareolata for the first time in Qatar. Regular field studies are needed to further address the knowledge gaps in terms of distribution, ecology, and biting habits of different mosquito species currently present in Qatar to accurately assess the risk of mosquito-borne diseases.

TITLE: Identification et caractérisation des moustiques de différents sites du Qatar en 2017­2019. ABSTRACT: Les maladies transmises par les moustiques posent de considérables risques en santé publique. La simple présence d'un cas de maladie à transmission vectorielle (MTV) introduit un risque pour la communauté locale lorsque associé à un vecteur, un hôte et des facteurs environnementaux compatibles. À ce jour il n'y a pas de programme de surveillance et de contrôle des vecteurs bien établi au Qatar, et de ce fait la probabilité de diffusion de MTV est indéterminée. C'est pourquoi il existe un besoin pressant de combler ce vide et de permettre une gestion effective des MTV. Ce travail présente les résultats de trois études de terrain successives conduites entre 2017 et 2019, dans l'objectif de caractériser les moustiques d'importance en santé publique et leur distribution au Qatar. Les résultats des piégeages d'adultes révèlent que le moustique domestique méridional Culex quinquefasciatus est l'espèce la plus répandue et abondante, suivie de Cx. perexiguus, les deux espèces présentant un risque pour la transmission du virus West Nile. L'ensemble des échantillonnages montrent que le vecteur du paludisme Anopheles stephensi est largement répandu y compris dans les zones urbanisées, ce qui suggère un risque de transmission locale du paludisme. Le moustique des zones humides Aedes caspius est également largement répandu, présentant un risque pour la transmission du virus de la fièvre de la Vallée du Rift. Le vecteur de la dengue Ae. aegypti n'a pas été détecté et peut être considéré ni répandu ni abondant, ce qui suggère un risque minimal de transmission locale des virus dengue, chikungunya et Zika. Il est intéressant de noter que cette étude a détecté la présence de Culiseta longiareolata pour la première fois au Qatar. Des études de terrain régulières sont nécessaires pour mieux combler les lacunes de connaissances en termes de distribution, écologie et comportement trophique des différentes espèces de moustiques présentes au Qatar, et d'évaluer plus précisément le risque de maladies transmises par les moustiques.
