This updated systematic review and meta-analysis investigated the current evidence regarding the efficacy of PDT for DS. Materials and methods: PubMed, Scopus, Web of Science, Google Scholar, and ProQuest were searched up to June 7, 2023. All relevant clinical trials were included. RevMan software was used for meta-analysis. Results: Elven randomized clinical trials (460 DS patients) were included. Eight studies assessed the efficacy of PDT vs. topical antifungal, while three studies assessed the adjunctive use of PDT (PDT+antifungal therapy) vs. topical antifungal therapy alone. The results revealed insignificant less efficacy of PDT in comparison to topical antifungal therapy on candida colonization at 15 days (MD: 0.95, 95% CI: -0.28, 2.19, p = 0.13), but comparable results at the end of follow-up (MD: -0.17, 95% CI: -1.33, 0.98, p = 0.77).

Objective: This study aimed to assess the state of awareness and extent of knowledge about COVID-19 among dental students from India, Pakistan, and Saudi Arabia. Materials and Methods: The present descriptive cross-sectional study was conducted on 872 participants from December 2020 to January 2021. Random sampling was performed using an electronic questionnaire. One-way analysis of variance and independent sample t-test were performed to assess and compare the mean knowledge score between different demographic data. Results: Approximately 60% (n = 520) of the responders were women and 40% responders were men (n = 352). The responders were from Saudi Arabia (36.9%; n = 322), India (34.2%; n = 298), and Pakistan (28.8%; n = 252). The difference within the subgroups was statistically nonsignificant (P > 0.05), indicating that dental students of all subparameters possessed equal knowledge on COVID-19. Conclusions: Dental students possess sufficient knowledge about COVID-19, qualifying them at least to work in a medical ward. However, more emphasis must be placed on infection prevention and control policies such as hand hygiene, personal protective equipment, and pre- and postexposure prophylaxis.

Here we convened, as part of this Delphi study, a diverse, multidisciplinary panel of 386 academic, health, non-governmental organization, government and other experts in COVID-19 response from 112 countries and territories to recommend specific actions to end this persistent global threat to public health. The panel developed a set of 41 consensus statements and 57 recommendations to governments, health systems, industry and other key stakeholders across six domains: communication; health systems; vaccination; prevention; treatment and care; and inequities. In the wake of nearly three years of fragmented global and national responses, it is instructive to note that three of the highest-ranked recommendations call for the adoption of whole-of-society and whole-of-government approaches1, while maintaining proven preve...

Material and Methods: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents. Results: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey. Although 72.5% of the respondents reported their intention to accept COVID-19 vaccines (dentists: 74.4%, dental students: 70.2%), there was a significant difference in agreement between dentists/dental students across countries; generally, respondents in upper-middle-, and high-income countries (UM-HICs) showed significantly higher acceptance rates compared to those in low- and lower-middle income countries (L-LMICs). Potential predictors of higher vaccine acceptance included being a dentist, be...

Their attitudes should also be up to the professional expectations. This study aimed to assess knowledge of HIV/AIDS infection and attitudes towards its patients among dental students in Saudi Arabia. Methods: A questionnaire was prepared and distributed among a sample of dental students in Saudi Arabia. Twenty questions related to knowledge, attitudes, and oral manifestation of HIV were presented. Results: A total of 405 questionnaires were completed (67% response rate). Participants showed low knowledge of safety regarding HIV (39.5%) and 44.2% indicated that they would take an HIV test after needle stick injury. The proportion of correct answers regarding transmission of HIV through saliva, cardiopulmonary resuscitation, and aerosols by hand pieces was 41%, 37.5%, and 26.4%, respectively. Almost 50% of the surveyed dental students expressed unwil...

While high-income countries are battling vaccine hesitancy, low-income and fragile nations are facing the double dilemma of vaccine hesitancy and lack of access to vaccines. There is inadequate information on any correlation between vaccine hesitancy and access to vaccines. Our study in a low-income nation aimed to fill this gap.MethodsIn the backdrop of a severe shortage of COVID-19 vaccines in Yemen, a low-income fragile nation, we conducted a nation-wide cross-sectional survey among its healthcare workers (HCWs), between 6 July and 10 August 2021. We evaluated factors influencing agreement to accept a COVID-19 vaccine and any potential correlation between vaccine acceptance and lack of access to vaccines.ResultsOverall, 61.7% (n = 975) of the 1,581 HCWs agreed to accept a COVID-19 vaccine. Only 45.4% of the participants agreed to have a...

Healthcare workers (HCWs) require adequate protection to avoid onward transmission and minimize burden on the healthcare system. Moreover, HCWs can also influence the general public into accepting the COVID-19 vaccine. Therefore, determining COVID-19 vaccine intention among HCWs is of paramount importance to plan tailor-made public health strategies to maximize vaccine coverage. A structured questionnaire was administered in February and March 2021 among HCWs in Saudi Arabia using convenience sampling, proceeding the launch of the vaccination campaign. HCWs from all administrative regions of Saudi Arabia were included in the study. In total, 674 out of 1124 HCWs responded and completed the survey (response rate 59.9%). About 65 percent of the HCWs intended to get vaccinated. The intention to vaccinate was significantly higher among HCWs 50 years of age or older, Saud...

Although several studies have been published on vaccine hesitancy among numerous populations, there is inadequate information on any potential correlation between vaccine acceptance and lack of access to vaccines. Our cross-sectional study in a low-income country aimed to fill this gap. Methods We conducted a nation-wide cross-sectional survey among the general population in Yemen, a low-income conflict country. Participants from all provinces in Yemen were included in the study. We evaluated factors that influence agreement to accept a COVID-19 vaccine and any potential correlation between vaccine hesitancy and lack of access to vaccines. Results Overall, 50.1% of the 5329 respondents agreed to accept a COVID-19 vaccine. Only 39.9% of participants agreed that they had access to a COVID-19 vaccine, with females indicating lower access tha...

Having faced with a six-year long conflict that has destroyed half of its healthcare facilities and displaced millions, predictions of infections and mortality in Yemen suggested a looming healthcare catastrophe. Difficulty in implementing coordinated lockdowns and preventive measures due to the daily labor working nature of the majority of the population, provided the perfect breeding ground for the SARS-CoV-2 virus. However, official figures of infections and mortality are very low and there have not been confirmed reports of excess mortality. This could indicate that Yemen is silently marching towards forced herd immunity. Seroprevalence studies will provide useful insight into the COVID-19 transmission trajectory in Yemen, which can serve as a guide in planning vaccine distribution strategies and allocating the limited funds wisely.

Several factors affect the CFR of COVID-19 leading to false disparities between nations, especially resource poor and fragile nations. Therefore, CFRs of resource poor and fragile nations should be carefully interpreted considering all associated parameters, to serve as a guide in planning public health strategies, and channeling the limited resources and donations appropriately, taking into consideration other equally important healthcare needs in crippled healthcare systems.

However, uncertainty or unwillingness to receive the vaccine could be a barrier in attaining sufficient vaccine coverage. Therefore, understanding the psychology of the population towards the vaccines against COVID-19 is of paramount importance. Our study was aimed at determining the predictors of COVID-19 vaccine intention in the Saudi Arabian population. A structured questionnaire guided by the ‘Report of the SAGE working group on vaccine hesitancy’ was administered during a span of two months among the general population from all administrative regions of Saudi Arabia, proceeding the launch of the vaccination campaign. In total, 879 out of 1600 subjects responded and completed the survey (response rate 54.9%). About 56 percent of the participants intended to be vaccinated. The predictors of a higher intention to vaccinate included those 50 years of age or older, male s...

Methods: The online search was conducted on Scopus database to retrieve all the articles published during 2004-2019 in the journal of Photodiagnosis and Photodynamic Therapy. The papers were identified and ranked as per the citation counts > 42. Additionally the authors; institute and country of origin; type of study and availability of funding in these highly cited articles was identified. VOS viewer software was used to analyze the occurrence of most commonly used keywords by the authors. Results: Majority of the highly cited studies published during last 15 years were literature reviews (n = 34) followed by the qualitative/quantitative studies (n = 15). The largest number of articles published were single nations without any collaborations (n = 45). The institutes publishing highest number of top cited articles included Massachusetts General Hospital, East Carolina University, 21 st Century Oncology, The Norwegian Radium Hospital and Trinity College Dublin. The country with largest number of top cited articles was USA. The keyword most commonly associated with the 50 top cited articles was 'Photodynamic therapy'. Conclusion: Extensively, various specialties of medicine and dentistry have been explored in the last 15 years in the journal of Photodiagnosis and Photodynamic Therapy. Based on citatations, we have highlighted those that can be considered as classic research.
