Structure of Aspergillus flavus populations associated with maize in Greece, Spain, and Serbia: Implications for aflatoxin biocontrol on a regional scale.

Aspergillus flavus is the most frequently identified producer of aflatoxins. Non-aflatoxigenic members of the A. flavus L strains are used in various continents as active ingredients of bioprotectants directed at preventing aflatoxin contamination by competitive displacement of aflatoxin producers. The current research examined the genetic diversity of A. flavus L strain across southern Europe to gain insights into the population structure and evolution of this species and to evaluate the prevalence of genotypes closely related to MUCL54911, the active ingredient of AF-X1. A total of 2173L strain isolates recovered from maize collected across Greece, Spain, and Serbia in 2020 and 2021 were subjected to simple sequence repeat (SSR) genotyping. The analysis revealed high diversity within and among countries and dozens of haplotypes shared. Linkage disequilibrium analysis indicated asexual reproduction and clonal evolution of A. flavus L strain resident in Europe. Moreover, haplotypes closely related to MUCL54911 were found to belong to the same vegetative compatibility group (VCG) IT006 and were relatively common in all three countries. The results indicate that IT006 is endemic to southern Europe and may be utilized as an aflatoxin mitigation tool for maize across the region without concern for potential adverse impacts associated with the introduction of an exotic microorganism.

A New α1-Globin Variant, Hb Ormylia [HBA1:c.63C > G; p.His21Gln]. Report of Eleven Cases in Northern Greece.

The first identification of a novel α1-Globin variant, Hb Ormylia in 11 Greeks originating from a small village, Ormylia, Chalkidiki, Greece is reported. The new genetic variant leads to the production of a hemoglobin variant that can be identified and quantified by High-Performance Liquid Chromatography. Capillary and classic electrophoresis were not informative. Direct DNA sequencing revealed a new mutation C > G mutation at codon 21 of α1 gene (His > Gln). The new variant has been named Hb Ormylia and this is the first description of this genetic variant of α1 gene in the literature.

Magnitude and determinants of excess total, age-specific and sex-specific all-cause mortality in 24 countries worldwide during 2020 and 2021: results on the impact of the COVID-19 pandemic from the C-MOR project.

INTRODUCTION: To examine the impact of the COVID-19 pandemic on mortality, we estimated excess all-cause mortality in 24 countries for 2020 and 2021, overall and stratified by sex and age. METHODS: Total, age-specific and sex-specific weekly all-cause mortality was collected for 2015-2021 and excess mortality for 2020 and 2021 was calculated by comparing weekly 2020 and 2021 age-standardised mortality rates against expected mortality, estimated based on historical data (2015-2019), accounting for seasonality, and long-term and short-term trends. Age-specific weekly excess mortality was similarly calculated using crude mortality rates. The association of country and pandemic-related variables with excess mortality was investigated using simple and multilevel regression models. RESULTS: Excess cumulative mortality for both 2020 and 2021 was found in Austria, Brazil, Belgium, Cyprus, England and Wales, Estonia, France, Georgia, Greece, Israel, Italy, Kazakhstan, Mauritius, Northern Ireland, Norway, Peru, Poland, Slovenia, Spain, Sweden, Ukraine, and the USA. Australia and Denmark experienced excess mortality only in 2021. Mauritius demonstrated a statistically significant decrease in all-cause mortality during both years. Weekly incidence of COVID-19 was significantly positively associated with excess mortality for both years, but the positive association was attenuated in 2021 as percentage of the population fully vaccinated increased. Stringency index of control measures was positively and negatively associated with excess mortality in 2020 and 2021, respectively. CONCLUSION: This study provides evidence of substantial excess mortality in most countries investigated during the first 2 years of the pandemic and suggests that COVID-19 incidence, stringency of control measures and vaccination rates interacted in determining the magnitude of excess mortality.

Preconceptional micronutrient adequacy among women in Greece: a prospective epidemiological study.

INTRODUCTION: The importance of micronutrient intake during the preconceptional and early pregnancy period for both maternal and fetal outcomes is well-known, however, relevant data are not available for Greek pregnant women. The aim of the present study is to delineate the nutritional status preceding conception among a representative cohort of Greek pregnant women. METHODS: This was a prospective study of pregnant women from routine care, recruited at 11+0-13+6 gestational weeks, between December 2020 and October 2022, at the 3rd Department of Obstetrics and Gynecology, Aristotle University of Thessaloniki, Greece. Eligible participants for the study included healthy pregnant women aged 20 years or older, possessing a proficient understanding of the Greek language, and not engaged in specific nutritional programs. A validated Food Frequency Questionnaire was applied to gather information regarding nutritional habits in the last 6 months prior to conception. The consumption of nutrients was compared to the reference intake levels suggested by the European Food Safety Authority. Further analyses between different participants' subgroups were performed. RESULTS: Overall, 1100 pregnant women (mean age: 32.4 ± 4.9 years) were enrolled. Almost all examined micronutrients' intake was significantly different from dietary reference values. Furthermore, nutrient adequacy ratio was below 60% in 6 out of 22 micronutrients examined, and Mean Adequacy Ratio was 93%. However, Mean Adequacy Ratio is characterized by extreme variance between the examined values. Iodine, folic acid, potassium, and vitamin D intake levels were significantly lower than the recommended intake levels (p < .001 for all), while vitamin K and niacin (p < .001 for both) were consumed in great extent. Sodium median intake, without calculating extra salt addition also exceeded the reference value levels (p = .03). Notably, magnesium intake exceeded the upper safety limits in 12.4% of the sample. CONCLUSION: Potential inadequacies in important micronutrients for uneventful pregnancy outcomes have been revealed.. Special attention is needed for magnesium to balance possible toxicity with evident benefits.

Leachability of hexavalent chromium from fly ash-marl mixtures in Sarigiol basin, Western Macedonia, Greece: environmental hazard and potential human health risk.

Hexavalent chromium (Cr (VI)) is an environmental contaminant brining high concerns due to its higher toxicity and mobility in comparison with trivalent chromium Cr(III). Cr (VI) has been linked with several adverse health effects, including respiratory diseases, lung cancer, and skin irritation. The primary sources of it in the environment are industrial activities.Most of the time, fly ash made of lignite can release Cr(VI) when it comes into contact with water in an aquatic environment. The objective of this study is the investigation of Cr (VI) concentration in leachates of fly ash and marl mixtures and the determination of its solubility under different pH conditions. Samples of fly ash were collected from the Power Plant of Agios Dimitrios. Additionally, samples of marl were collected from the mine of South Field, and both samples were mixed and prepared in in different proportions (% w.t.). The leaching experiments were carried out according to the EN-12457/1-4 (2003) standard under different pH conditions and chemical analysis of the leachates were performed by spectrophotometry with diphenylcarbazide (DPC). The environmental footprint of Cr (VI) in the study area was significant, especially in mixtures containing higher concentrations of fly ash. A critical pH range between 6 to 12 is observed. At acidic pH values, a high release of Cr (VI) was observed, while at the mentioned critical values (pH 10-12), a gradual decrease in its leachability was noticed. The high concentrations of Cr (VI) in the industrial area studied require immediate actions in terms of managing and limiting the potential hazardous impacts on the environment and by extension on the public health by developing appropriate prevention strategies.

Emigration of Greek Knowledge to the Arab World.

The period described in this chapter reflects activity prior to the establishment of surgical centers in Europe in the twelfth century. It is a kind of prologue to the reintroduction of high-quality surgical practice. Religious squabbles within Christianity led to European medicine and surgery, the principles of which were written in Greek, being transported eastwards into the region newly dominated by Islam. There the works were translated into Arabic and during three to four hundred years, the works were not only retained but were enriched by contributions from within Arab culture. This evolution naturally enough came to affect what happened next. However, one thing is clear and was even commented on as early as by Albucasis. The surgeon's respect and distinction within society had depreciated during the sojourn of medical science in the Islamic world, with physicians being regarded as distinctly superior beings. With regard to specific details related to opening the head there was broad consistency between the various authors all of whom seem to have been greatly influenced by Paul of Ægina. Thus, there is no mention of the crown trepan. Opening the skull was performed with the non-perforating trepans making small holes which were connected with chisels or lenticulars. The indication to do this was separation of the dura from the bone. Whether or not the sutures should be avoided when trepanning is not a topic mentioned in these writings. There was also no recommendation for prophylactic trepanation.

Psychotropic medicine use without current or prior medical advice, storage at home and association with perceived stress in a primary health care setting in Greece / Uso de medicamentos psicotrópicos sin consejo médico actual o previo, almacenamiento en el hogar y asociación con estrés percibido en un entorno de atención primaria en Grecia

Objective: Psychotropic medicines use alters according to socio-economic factors and perceived stress. The study aimed to assess the prevalence of use of psychotropic medicines and supplements (PMS) without medical advice, including storage at home, and its relationship with socio-demographic characteristics and perceived stress in primary care patients. Materials and methods: A cross-sectional sample of adult attendees in an urban primary care unit in Crete, Greece, were surveyed during regularly scheduled appointments during a three-week period in October 2020. A questionnaire was distributed to investigate PMS use during the last 12 months. The validated Greek version of Perceived Stress Scale (PSS-14) was adopted to measure perceived stress. Results: Of 263 respondents (mean age 46.3±14.5 years; 66.5% females), 101 (38.4%; 95%CI 33.1–43.7%) recalled having psychotropic medicines stored at home cabinets and 72 (27.4%; 95%CI 22.4–32.3%) reported using PMS without medical advice in the last 12 months. Conclusions: This study revealed a high prevalence of PMS use without medical advice, including storage at home. People>59 years of age, experiencing irregular sleep and scoring high in PSS, displayed increased prevalence of storing PMS at home or using them without medical advice. The findings could potentially inform primary care providers to focus on patients most likely to be users of PMS without medical advice.(AU)

Objetivo: El uso de medicamentos psicotrópicos cambia según los factores socioeconómicos y el estrés percibido. El estudio tuvo como objetivo evaluar la prevalencia de uso de medicamentos y suplementos psicotrópicos (MSP) sin consejo médico, incluido el almacenamiento en el hogar y su relación con las características sociodemográficas y el estrés inferido en pacientes de atención primaria. Materiales y métodos: Se encuestó a una muestra transversal de asistentes adultos en una Unidad de Atención Primaria Urbana en Crete, Grecia, durante citas programadas regularmente durante un periodo de tres semanas en Octubre de 2020. Se distribuyó un cuestionario para investigar el uso de MSP durante los últimos 12 meses. Se adoptó la versión griega validada de la Escala de Estrés Percibido (Perceived Stress Scale 14, PSS-14) para medir el estrés percibido. Resultado: De 263 encuestados (edad media 46,3 ± 14,5 años; 66,5% mujeres), 101 (38,4%; IC 95%; 33,1-43,7%) recordaban tener medicamentos psicotrópicos almacenados en los armarios de sus casas y 72 (27,4%; IC 95%; 22,4-32,3%) informó haber usado MSP sin consejo médico en los últimos 12 meses. Conclusiones: Este estudio reveló una alta prevalencia de uso de MSP sin consejo médico, incluido el almacenamiento en el hogar. Las personas mayores de 59 años, que experimentaron sueño irregular y puntuaron alto en PSS, mostraron una mayor prevalencia de almacenar MSP en casa o usarlos sin consejo médico. Los hallazgos podrían informar potencialmente a los proveedores de atención primaria para que se centren en los pacientes con mayor probabilidad de usar MSP sin consejo médico.(AU)

NMR Analysis of Extra Virgin Olive Oil of the Epirus Region of Greece with Emphasis on Selected Phenolic Compounds.

Extra virgin olive oil (EVOO) is recognized for its numerous health benefits, attributed to its rich phenolic components. NMR has emerged as a prevalent technique for precisely identifying these compounds. Among Mediterranean countries, Greece stands as the third-largest producer of olives, with the Epirus region notably advancing in olive cultivation, contributing significantly to the dynamic growth of the region. In this study, an NMR method was employed based on the acquisition of a 1H NMR spectrum along with multiple resonant suppression in order to increase the sensitivity. Using the above method, 198 samples of extra virgin olive oil, primarily sourced from the Epirus region, were analyzed, and both the qualitative and quantitative aspects of the phenolic compounds were obtained. In addition, we examined the effects of various factors such as variety, harvest month, and region origin on the phenolic compounds' concentration. The results revealed an average total phenolic content of 246 mg/kg, closely approaching the EU health claim limit of 250 mg/kg. Approximately 15% of the samples were confidently characterized as high-phenolic olive oil. The highest concentrations were observed in the Thesprotia samples, with several Lianolia varieties exceeding the total phenolic content of 400 mg/kg. Statistical tests demonstrated a significant influence of the olive variety and the month of fruit harvest on phenolic component concentration, followed by the region of origin. A very strong correlation was noted between the total phenolics content and the levels of oleocanthal and oleacein, with a correlation coefficient (r) of 0.924. Upon optimization of all factors affecting olive oil quality, the majority of the EVOOs from the Epirus region have the potential to be characterized as high in phenolic content.

The Fagerström Test for Nicotine Dependence, as a prognostic factor, in current smokers with and without COPD: A cross-sectional study in northern Greece.

BACKGROUND: Smoking poses the most common risk factor for chronic obstructive pulmonary disease (COPD) and aggravates disease progression. Tobacco dependence inhibits smoking cessation and may affect smoking patterns that increase tobacco exposure and predispose to lung function decline. AIMS AND OBJECTIVES: We aimed to assess tobacco dependence in current smokers with and without COPD and evaluate its role in disease development. METHOD: This cross-sectional study was conducted in Greek rural areas. Current smokers completed the Fagerström Test for Nicotine Dependence and were classified into COPD and non-COPD groups based on spirometry parameters. RESULTS: Among current smokers, 288 participants comprised the non-COPD and 71 the COPD group. Both presented moderate tobacco dependence, but smokers with COPD started to smoke earlier in the morning. Multiple logistic regression analysis revealed higher COPD prevalence in smokers with higher scores in the Fagerström test (odds ratio OR = 1.12, 95% confidence interval [1.01 - 1.24]) and older age (OR = 1.06 [1.03 - 1.09]), independently of pack-years smoking index. Multiple linear regression analysis in smokers with COPD showed that the forced expiratory volume in the 1st second decreased by 2.3% of the predicted value for each point increase in the Fagerström Test and 0.59% for each year of age, independently of participants' sex and pack-years smoking index. CONCLUSION: The Fagerström score appears to indicate a higher probability for COPD and lung function deterioration when assessed along with age in current smokers. Smoking cessation support programs are fundamental to COPD prevention and management.

Comparative analysis of CAMS aerosol optical depth data and AERONET observations in the Eastern Mediterranean over 19 years.

Aerosol optical depth (AOD) is an essential metric for evaluating the atmospheric aerosol load and its impacts on climate, air quality, and public health. In this study, the AOD data from the Copernicus Atmosphere Monitoring Service (CAMS) were validated against ground-based measurements from the Aerosol Robotic Network (AERONET) throughout the Eastern Mediterranean, a region characterized by diverse aerosol types and sources. A comparative analysis was performed on 3-hourly CAMS AOD values at 550 nm against observations from 20 AERONET stations across Cyprus, Greece, Israel, Egypt, and Turkey from 2003 to 2021. The CAMS AOD data exhibited a good overall agreement with AERONET AOD data, demonstrated by a Pearson correlation coefficient of 0.77, a mean absolute error (MAE) of 0.08, and a root mean square error (RMSE) of 0.11. Nonetheless, spatial and temporal variations were observed in the CAMS AOD data performance, with site-specific correlation coefficients ranging from 0.57 to 0.85, the lowest correlations occurring in Egypt and the highest in Greece. An underestimation of CAMS AOD was noted at inland sites with high AOD levels, while a better agreement was observed at coastal sites with lower AOD levels. The diurnal variation analysis indicated improved CAMS reanalysis performance during the afternoon and evening hours. Seasonally, CAMS reanalysis showed better agreement with AERONET AODs in spring and autumn, with lower correlation coefficients noted in summer and winter. This study marks the first comprehensive validation of CAMS AOD performance in the Eastern Mediterranean, offering significant enhancements for regional air quality and climate modeling, and underscores the essential role of consistent validation in refining aerosol estimations within this complex and dynamic geographic setting.

This meeting report summarizes lectures by the invited speakers and highlights advances in the field.

Identification of lentils (Lens culinaris Medik) from Eglouvi (Lefkada, Greece) based on rare earth elements profile combined with chemometrics.

An analytical approach has been developed to verify the authenticity of premium lentils originating from Eglouvi, Lefkada, Greece. The method relies on the digestion of samples followed by the analysis of their rare earth elements (REEs) content. Lentils originating from Eglouvi exhibit higher content in most REEs compared to lentils from other regions as well as distinct Sc/Y and Sc/Yb concentration ratios. Principal component analysis effectively segregates "Eglouvi" lentils into a distinct cluster. Soft Independent Modelling of Class Analogy (SIMCA) successfully models "Eglouvi" lentils. Significant enhancement in model specificity was achieved upon inclusion of Sc/Y and Sc/Yb concentration ratios as additional variables. The model is capable of detecting adulteration in blends of Eglouvi lentils, with a minimum rejection threshold of 4.6% w/w for Greek lentil adulterants and 6.0% w/w for imported lentil adulterants.

Novel Pathogenic Variants Leading to Sporadic Amyotrophic Lateral Sclerosis in Greek Patients.

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive disease that affects motor neurons, leading to paralysis and death usually 3-5 years after the onset of symptoms. The investigation of both sporadic and familial ALS highlighted four main genes that contribute to the pathogenesis of the disease: SOD1, FUS, TARDBP and C9orf72. This study aims to provide a comprehensive investigation of genetic variants found in SOD1, FUS and TARDBP genes in Greek sporadic ALS (sALS) cases. Our sequencing analysis of the coding regions of the abovementioned genes that include the majority of the variants that lead to ALS in 32 sALS patients and 3 healthy relatives revealed 6 variants in SOD1, 19 variants in FUS and 37 variants in TARDBP, of which the SOD1 p.D90A and the FUS c.*356G>A (rs886051940) variants have been previously associated with ALS, while two novel nonsense pathogenic variants were also identified, namely FUS p.R241* and TDP-43 p.Y214*. Our study contributes to the worldwide effort toward clarifying the genetic basis of sALS to better understand the disease's molecular pathology.

A Chronic Obstructive Pulmonary Disease Self-Management Intervention for Improving Patient-Reported Outcomes in Primary Care in Greece.

Background and Objectives: Self-management programs are essential for increasing COPD patient participation and autonomy in making appropriate decisions about their chronic condition. The present study aimed to assess the impact of COPD self-management interventions on quality of life, functional status, patient education, depression, and anxiety in primary care. Materials and Methods: We conducted a randomized controlled trial recruiting patients with COPD (GOLD A and B) from four primary care centers in Crete, Greece, with one intervention group (n = 40) receiving self-management educational support and one control group (n = 80) receiving usual care. To measure quality of life, functional status, patient education, depression, and anxiety, we used patient-reported outcome measures (PROMs) at baseline and 6 months post-intervention, including the Short-Form Health survey (SF-12), Clinical COPD Questionnaire (CCQ), mMRC, Beck Anxiety Inventory (BAI), Beck Depression Inventory, Health Education Impact Questionnaire (HeiQ), and Health Literacy Questionnaire (HLQ). Results: At the end of the 6-month intervention, most PROMs improved significantly in the intervention group (p < 0.05) but did not show significant changes in the control group. The greatest improvements at follow-up compared to baseline measurements were observed for dyspnea (mMRC-38.6%), anxiety (BAI-35%), depression (BDI-20.2%), COPD health status (CCQ-34.1%), and the actively managing my health subscale of HLQ (23.5%). Conclusions: Our results suggest that a self-management intervention could be an effective strategy for improving PROMs in primary care. Although more research is needed to identify the long-term effects of such interventional programs, policymakers could implement similar programs to improve the overall health of these patients.

Evaluation of Lower Urinary Tract Symptoms in Males and Urinary Incontinence in Females in Primary Health Care in Greece.

Background and Objectives: The significant prevalence of Lower Urinary Tract Symptoms (LUTS), erectile dysfunction (ED), and associated adverse effects calls for increased attention in primary care settings. In Greece, there is a lack of sufficient data for LUTS and ED screening in primary care. Therefore, the aim of our study was to estimate the prevalence of LUTS and ED, identify associated risk factors, and evaluate their impact on quality of life among adult primary healthcare users aged 40 years and older in Crete, Greece. Materials and Methods: A cross-sectional study was conducted to explore the prevalence of LUTS and ED in 1746 primary health care users visiting rural primary health care practices in Crete, Greece. Participants underwent a comprehensive evaluation including demographic parameters, screening for LUTS utilizing the validated International Prostate Symptoms Score (IPSS) questionnaire and for ED using the International Index of Erectile Function (IIEF-5), in males, and for urinary incontinence in women with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Participants with a prior diagnosis of LUTS or ED were excluded (n = 183). Results: Out of 536 participants finally included (n = 1746 screened), 32% of males and 36% of females exhibited moderate to severe LUTS. Following adjustments, we identified advanced age, retirement, and the presence of diabetes type 2 as factors associated with the occurrence of LUTS in men. Patients with LUTS also had a substantially increased likelihood of experiencing ED. Moreover, it was observed that women with hypertension or diabetes type 2 and lower education levels face an increased likelihood of developing LUTS, which adversely affects their quality of life. Conclusions: In conclusion, the findings of this study reveal a high occurrence of LUTS and ED in adults aged 40 years and older who utilize primary healthcare services, with a negative impact on their quality of life.

Cross-country variations in the caregiver role: evidence from the ENTWINE-iCohort study.

BACKGROUND: Globally, economically developed countries face similar ageing demographics and the challenge of a 'care gap', yet they vary due to different care and formal support systems, and different cultural and societal norms around illness and care. The aim of this exploratory study was to examine cross-country variations in caregiver motivations, willingness, values, meaning in life, illness beliefs, and experiences of wellbeing, gain, health-related quality of life, burden and depression, across 6 European countries and Israel. Cross-country differences in the above-mentioned informal caregiver experiences are rarely described. METHODS: An online survey (ENTWINE-iCohort) was conducted using validated measures wherever possible. This paper utilises data from 879 caregivers and seven countries (Greece, Italy, the Netherlands, Poland, Sweden, the UK, and Israel). RESULTS: No consistent finding supporting the concurrent relationship between caregiver support policies/country culture and caregiver motivations/willingness was found. Caregivers in countries typically characterised by individualist cultures reported lower familism, higher self-enhancement values, and greater perceived illness threat compared to more collectivist countries. Search for meaning was higher in poorer countries than in wealthier countries. Higher negative caregiver experiences (e.g., burden) and lower positive experiences (e.g., wellbeing) were generally observed in countries with underdeveloped caregiver support as compared to countries with more developed formal support systems. CONCLUSIONS: Cross-country variations can be explained to varying degrees by national policies around care (or their absence) and country cultural contexts. The results emphasise the importance of formal support services for achieving positive caregiver experiences, and help inform the development of policies and measures to support caregivers in Europe and Israel.

Association between variants in TCF7L2, CTRB1/2, and GLP-1R genes and response to therapy with glucagon-like peptide-1 receptor agonists.

OBJECTIVES: The factors determining the response to treatment with glucagon-like peptide-1 receptor agonists (GLP-1- RAs) have not been clarified. The present study investigated the association between polymorphisms in TCF7L2, CTRB1/2, and GLP-1 R genes and response to GLP-1 RAs regarding glycemic control and weight loss among Greek patients with type 2 diabetes mellitus (T2DM). METHODS: Patients (n = 191) treated with GLP-1 RAs for at least 6 months were included. Participants were genotyped for TCF7L2 rs7903146 (C>T), CTRB1/2 rs7202877 (T>G) and GLP-1 R rs367543060 (C>T) polymorphisms. Clinical and laboratory parameters were measured before, 3, and 6 months after treatment initiation. The patients were classified into responders and non-responders according to specific criteria. RESULTS: Carriers of at least one rs7903146 'T' allele and rs7202877 'G' allele presented similar glucose control and weight loss response to GLP-1 RAs with the respective homozygous wild-type genotypes [odds ratio (OR): 1.08, 95% confidence interval (CI): 0.5, 2.31, p = 0.85 and OR: 1.35, 95% CI: 0.66, 2.76, p = 0.42; OR: 1.4, 95% CI: 0.56, 3.47, p = 0.47 and OR: 1.28, 95% CI: 0.55, 2.98, p = 0.57, respectively]. Regarding the GLP-1 R polymorphism, all participants were homozygous for the wild-type allele; thus, no comparisons were feasible. Female sex (p = 0.03) and lower baseline weight (p = 0.024) were associated with an improved glycemic and weight loss response, respectively. CONCLUSION: There is no evidence suggesting a role for the variants studied in response to GLP-1 RA therapy in people with T2DM. However, specific demographic and clinical factors may be related to a better response to treatment with these agents.

Awareness, knowledge and attitudes of human papillomavirus infection, screening and vaccination: a survey study in Greece.

PURPOSE: To evaluate the awareness and existing knowledge of a portion of the Greek population about prevention, screening, and HPV vaccination. METHODS: A questionnaire designed in Google forms has been distributed through social media between June 2021 and December 2021 in men and women aged > 16 years old. Statistical analysis was performed using the SPSS 20.0 program. Inferential analysis was performed to evaluate differences in responses among men and women. RESULTS: We enrolled 2685 participants. Of those, 2285 were women, 386 were men, while 14 respondents chose not to respond to this question. Various age groups were detected with those aged between 26 and 30 years old being the predominant one. Participants with a higher education constituted 36.5% of the population. Most respondents were married (59.8%). In socioeconomic terms 75.5% of participants were employed whereas, monthly income ranged between 1000 and 1500 euros in the predominant group (36.8%). Only 40% of females and 3.9% of males were vaccinated against HPV. Adolescent immunization, acceptability rates reached 92.7% among female and 82.1% among male responders. Although, only a small proportion of the participants were not aware of the existence of HPV, 24.1% of males and 23.4% of females had the impression that condom use may provide absolute immunity to HPV and only 51.6% of males and 60.4% of females were aware about the high prevalence of HPV in the general population. Logistic regression analysis indicated that male participants as well as those aged > 50 years and those choosing to reject vaccination had decreased knowledge of the basic pathophysiology of HPV infection, as well as knowledge related to the existence and use of HPV DNA as a screening tool and the existence and efficacy of HPV vaccination. CONCLUSION: Our results indicate that although awareness of the existence of HPV infection is high in Greek general population, the actual perception of the pathophysiology of transmission and importance of HPV testing and vaccination is low. Targeting specific population groups is essential to help increase HPV coverage and screening.
