Assessing hesitancy towards paediatric vaccines among healthcare professionals: A descriptive cross-sectional study from the United Arab Emirates
Background: Vaccination is one of the most effective public health interventions, preventing millions of deaths globally. However, vaccine hesitancy persists, not only among the public, but also among healthcare professionals (HCPs), who serve as key sources of vaccine information. This study assesses HCPs’ vaccination attitudes and estimates the prevalence and determinants of vaccine hesitancy in the UAE. Design and methods: This cross-sectional, descriptive study surveyed HCPs across the UAE from March to October 2024 using a 57-item questionnaire adapted from previous literature. Univariate, bivariate (chi-squared test), and multivariate (logistic regression) analyses were conducted. Results: HCPs demonstrated generally positive attitudes towards paediatric vaccinations, with 84.29% expressing confidence in vaccine safety and efficacy. However, significant knowledge gaps were identified, particularly regarding vaccine adjuvants and long-term safety. Hesitancy was highest among mid-level professionals, including nurses, dentists, and pharmacists, with concerns about vaccine safety (47.87%) and adverse effects (57.67%) being major drivers. Additionally, 85.77% exhibited caution towards newly introduced vaccines, preferring to wait for broader community uptake. Time constraints limited vaccine discussions, and 71.9% of HCPs had never received formal training on addressing hesitancy. Conclusion: While HCPs generally support paediatric vaccinations, knowledge gaps and hesitancy towards new vaccines persist. Targeted professional education, particularly in vaccine safety and communication strategies, is crucial to strengthening vaccine advocacy. Addressing these gaps through tailored training programmes may enhance HCPs’ ability to effectively counter vaccine hesitancy and sustain high immunization coverage.

Vaccine practices, literacy, and hesitancy among parents in the United Arab Emirates
Background: Immunisation is one of public health’s greatest success stories, yet, annually, 20 million children miss out entirely or partially on routine immunisation. National immunisation estimates have the United Arab Emirates (UAE) lagging behind with 4% of children under the age of 1 not having received any vaccines. Vaccine hesitancy is considered one of the biggest barriers to vaccination. This study aims to evaluate the UAE’s parents’ vaccination attitudes and practices as well as estimate vaccine hesitancy’s prevalence and determinants. Methodology: This cross-sectional, descriptive study collected data from parents across the UAE during the months of March and April 2024. The 60-item questionnaire included the Parental Attitudes towards Childhood Vaccines scale (PACV), the Vaccine Hesitancy Scale, and the Digital Vaccine Literacy (DVL) scale. Univariate, bivariate (chi-squared test), and multivariate (logistic regression) analyses were conducted. Results: A total of 550 responses were retained. 84.55% of participants were female (n = 465/550), half were middle-aged (31–45 years old), and 21.09% (n = 116/550) were healthcare workers. 94.36% (n = 519/550) had their child/children receive all mandated vaccines. Only 39.82% (n = 219/550) found their level of knowledge about childhood vaccinations to be good/excellent. 70.11% (n = 386/550) of participants had high digital vaccine literacy. More than 95% had positive attitudes towards measles, meningitis, and pertussis vaccines. 14.00% (n = 77/550) were identified as vaccine-hesitant according to the PACV. Overall, using general practitioner/ paediatrician as a knowledge source, digital vaccine literacy, perceived children’s vaccine knowledge, and nationality were associated with lower vaccine hesitancy status. Conclusion: Vaccine hesitancy exists and is prevalent in the UAE; however, the majority of participants reported high trust in vaccines, the local healthcare systems and physicians. Vaccine hesitancy can be tackled but will require tailored solutions and proactive healthcare workers.

Contemporary Trends of Holmium Laser Enucleation of the Prostate Utilization in the United States: A Comprehensive Analysis Using the National Surgical Quality Improvement Program Database (2011–2020)
Introduction: The most recent American Urological Association (AUA) Guidelines advocated laser enucleation of the prostate (LEP) as a size-independent surgical option for benign prostatic hyperplasia (BPH). Despite its endorsement by AUA and the growing body of evidence supporting its safety and efficacy, the utilization of LEP remains limited in the United States. This study aimed to evaluate the utilization trends and perioperative outcomes of LEP compared with other surgical procedures used for BPH management. Methods: A retrospective cohort analysis was performed using American College of Surgeons National Surgical Quality Improvement Program data from 2011 to 2020. Patients undergoing prostatectomy for BPH were identified using specific current procedural terminology (CPT) codes. Baseline demographic data, preoperative risk factors, and postoperative outcomes were collected. Multivariable logistic regression was employed to assess predictors of holmium laser enucleation of the prostate (HoLEP) utilization and postoperative complications. Results: Out of 8,415,549 patients, 95,144 underwent prostatectomy for BPH. Procedures included HoLEP 5305 cases, transurethral resection of the prostate (TURP) 57,803 cases, repeated TURP (re-TURP) 5549 cases, photoselective vaporization of the prostate (PVP) 23,739 cases, and simple prostatectomy 2748 cases. HoLEP utilization showed a gradual increase, from 4.8% in 2015 to 7.6% in 2020. Multivariable regression revealed that HoLEP selection significantly increased from 2016 to 2020 (odds ratio [OR]: 1.251, p < 0.001), and there was less likelihood of HoLEP selection for African American patients (OR: 0.752, p < 0.001). HoLEP had significantly lower complication rates, including urinary tract infections, blood transfusions, 30-day readmission, and reoperation. Conclusion: Despite underutilization, the adoption of HoLEP has slightly increased since 2015, rising from 4.8% in 2015 to 7.6% in 2020. The underutilization could be attributed to a lack of availability and the steep learning curve.

Emirati Adolescents’ and Young Adults’ Usage of Social Media for Health Information
During the COVID-19 pandemic and in the years after, adolescents’ and young adults’ (AYAs) usage of social media increased. Social media has been shown to influence both the physical and mental behaviour of AYAs. The Emirates’ AYAs are among the world’s heaviest consumers of social media. This study aims to explore the usage of social media networks by AYAs for sharing and looking up health information, as well as interacting with local health systems, with a special focus on doctors and social media. This cross-sectional, descriptive study was used to collect comprehensive data from Arabic- and English-speaking Emirati students in grades 7 through 12 and university students between the months of December 2022 and April 2023. A total of 876 out of 930 responses were included. Of the responses, 27.71% were university students, with another 46.46% in grades 11 and 12. Three-fourths had a hospital or clinic visit in the last 6 months and 79.11% had good health perception. Smartphones were the most commonly used devices, at 92.12%. A total of 74.7% reported being able to obtain useful health information, with 40% having had a health decision influenced by it. Posting information on social media was not common, with only 32% posting such content (most commonly mood-related). Health information on social media by health authorities was considered the most trustworthy, with celebrities being the least trustworthy. More than half of AYAs searched for a physician before a visit, and the majority would not mind having a rash picture being posted on a public website if consent (verbal or written) was taken. Social media can influence the various health decisions an AYA might take and which doctors they might choose to see. Physicians should consider their presence and the content they present on social media carefully.

Assessing the Link between Diabetic Metabolic Dysregulation and Breast Cancer Progression
Diabetes mellitus is a burdensome disease that affects various cellular functions through altered glucose metabolism. Several reports have linked diabetes to cancer development; however, the exact molecular mechanism of how diabetes-related traits contribute to cancer progression is not fully understood. The current study aimed to explore the molecular mechanism underlying the potential effect of hyperglycemia combined with hyperinsulinemia on the progression of breast cancer cells. To this end, gene dysregulation induced by the exposure of MCF7 breast cancer cells to hyperglycemia (HG), or a combination of hyperglycemia and hyperinsulinemia (HGI), was analyzed using a microarray gene expression assay. Hyperglycemia combined with hyperinsulinemia induced differential expression of 45 genes (greater than or equal to two-fold), which were not shared by other treatments. On the other hand, in silico analysis performed using a publicly available dataset (GEO: GSE150586) revealed differential upregulation of 15 genes in the breast tumor tissues of diabetic patients with breast cancer when compared with breast cancer patients with no diabetes. SLC26A11, ALDH1A3, MED20, PABPC4 and SCP2 were among the top upregulated genes in both microarray data and the in silico analysis. In conclusion, hyperglycemia combined with hyperinsulinemia caused a likely unique signature that contributes to acquiring more carcinogenic traits. Indeed, these findings might potentially add emphasis on how monitoring diabetes-related metabolic alteration as an adjunct to diabetes therapy is important in improving breast cancer outcomes. However, further detailed studies are required to decipher the role of the highlighted genes, in this study, in the pathogenesis of breast cancer in patients with a different glycemic index.

Breast cancer knowledge and practices amongst women in Algeria
Purpose The present study aims at investigating how Algerian women feel about Breast Cancer (BC) and Breast Self-Examination (BSE) in terms of knowledge and attitude and to determine the factors associated with performing BSE and its reluctance. Methods We carried out a cross-sectional survey between October 14, 2021 and November 14, 2022, targeting Algerian females aged more than 18 years and living in the country using a self-administered questionnaire. Results A total of 436 participants were involved in this study among which 41.28% were aged between 21 and 30 years and 34.86% were aged between 31 and 40 years. The average level of correct responses with regard to knowledge about BC was estimated at 51.31%, whereas it was 32.93% concerning knowledge about BC risk factors. Family history was the less reported incriminating factor for developing BC among the asked women (7.34%). Concerning alarming signs of BC, the current study revealed that Algerian women were less knowledgeable about breast dimpling-puckering (44.27%), breast inward traction (50.23%), breast redness (54.13%), and nipple position change (54.13%). In terms of belief in the utility of BSE in the early detection of BC, almost all the participants (97.98%) were convinced of its utility, whereas 96.33% of them showed an interest in learning more about it. In what concerns the early screening tests, approximately, four-fifth of the participant (77.52%) heard about them, while 94.72% believed that its early detection could reduce the disease’s severity and mortality. Conclusion These findings revealed an insufficient level of knowledge concerning BC, especially in regard to its risk factors and some alarming signs as well as a lack of knowledge about BSE and other BC screening tests; hence the necessity of awareness campaigns about this disease that should target categories with the lowest level of knowledge.
