An ovarian mature cystic teratoma evolving in squamous cell carcinoma: A case report and review of the literature

Mature cystic teratomas (MCT), also known as dermoid cysts, are the most common ovarian germ cell tumors and the most common ovarian neoplasms in patients younger than 20 years. Malignant transformation (MT) is a rare complication of MCTs which may occur in 1–2% of the cases. Squamous cell carcinoma (SCC) is the most frequent histology arising from MCTs and its appearance depends on diverse risk factors such as patient's age, the size of the tumor and levels of serum tumor markers. Diagnosis and treatment constitute a big challenge due to the rarity and the aggressive course of this entity. Adjuvant chemotherapy has a leading role in the treatment of MCT-arising SCC, while the use of radiotherapy or chemoradiation is still under consideration. Herein, we report a case of a post-menopausal woman, presenting with mild symptoms and a large pelvic mass deriving from the left ovary occurring as dermoid cyst. Simultaneously, we review the literature stressing out the prognostic factors and the treatment options for MCT arising SCC according to traditional and new therapy-strategies

Hypertension-mediated organ damage regression associates with blood pressure variability improvement three years after successful treatment initiation in essential hypertension

Blood pressure variability (BPV) has been associated with the development, progression, and severity of cardiovascular (CV) organ damage and an increased risk of CV morbidity and mortality. We aimed to explore any association between short-term BPV reduction and hypertension-mediated organ damage (HMOD) regression in hypertensive patients 3-year post-treatment initiation regarding BP control. 24-h ambulatory blood pressure monitoring (24 h ABPM) was performed at baseline in 180 newly diagnosed and never-treated hypertensive patients. We measured 24 h average systolic (24 h SBP) and diastolic BP (24 h DBP) as well as 24 h systolic (sBPV) and diastolic BPV (dBPV). Patients were initially evaluated and 3 years later regarding arterial stiffness (PWV), left ventricular hypertrophy (LVMI), carotid intima-media thickness (cIMT), 24 h microalbumin levels (MAU), and coronary flow reserve (CFR). Successful BP treatment was defined as 24 h SBP/DBP < 130/80 mm Hg based on 2nd ABPM and subsequently, patients were characterized as controlled (n = 119, age = 53 ± 11 years) or non-controlled (n = 61, age = 47 ± 11 years) regarding their BP levels. In the whole population and the controlled group, 24 h SBP/DBP, sBPV/dBPV, LVMI, and IMT were decreased. Additionally, LVMI improvement was related with both sBPV (p <.001) and dBPV reduction (r =.18, p =.02 and r =.20, p =.03, respectively). In non-controlled hypertensives, PWV was increased. In multiple linear regression analysis, sBPV and dBPV reduction predicted LVMI improvement in total population and controlled group independently of initial office SBP, mean BP, and 24 h-SBP levels. In middle-aged hypertensive patients, a 3-year antihypertensive treatment within normal BP limits, confirmed by 24-h ABPM, leads to CV risk reduction associated with sBPV and dBPV improvement. © 2021 The Authors.

The Role of Colchicine in Treating Postoperative and Post-catheter Ablation Atrial Fibrillation

Purpose: The goal of this review was to summarize, analyze, and compare trials studying the efficacy of colchicine in the prevention of atrial fibrillation (AF) post-operatively (POAF) and post–catheter ablation. Ongoing studies and current guidelines are also presented and reviewed. Methods: Published studies on the field were identified through a literature search of the PubMed and clinicaltrials.gov databases. Findings: Four original studies regarding POAF, two original studies regarding post–catheter ablation AF, and six meta-analyses were identified. In addition, the 3 most recent guidelines/expert consensus documents were scrutinized. Implications: AF occurs frequently after cardiac surgery (POAF) and catheter pulmonary vein isolation (postablation AF) and is associated with increased cardiovascular morbidity. A number of trials over the last few years have investigated the role of colchicine in the prevention of POAF and postablation AF targeting the local and systemic inflammatory process that leads to initiation and maintenance of AF. Available data imply that colchicine may have a preventive role in POAF and/or postablation AF. However, certain limitations of these studies underline the need for further investigation. © 2018 Elsevier Inc

Greater decline of acute stroke admissions compared with acute coronary syndromes during COVID-19 outbreak in Greece: Cerebro/cardiovascular implications amidst a second wave surge

Background and purpose: A remarkable decline in admissions for acute stroke and acute coronary syndrome (ACS) has been reported in countries severely hit by the COVID-19 pandemic. However, limited data are available from countries with less COVID-19 burden focusing on concurrent stroke and ACS hospitalisation rates from the same population. Methods: The study was conducted in three geographically and demographically representative COVID-19 referral university hospitals in Greece. We recorded the rate of stroke and ACS hospital admissions during a 6-week period of the COVID-19 outbreak in 2020 and compared them with the rates of the corresponding period in 2019. Results: We found a greater relative reduction of stroke admissions (51% [35 vs. 71]; incidence rate ratio [IRR]: 0.49, p = 0.001) compared with ACS admissions (27% [123 vs. 168]; IRR: 0.73, p = 0.009) during the COVID-19 outbreak (p = 0.097). Fewer older (>65 years) patients (stroke: 34.3% vs. 45.1%, odds ratio [OR]: 0.64, p = 0.291; ACS: 39.8% vs. 54.2%, OR: 0.56, p = 0.016) were admitted during the COVID-19 compared with the control period. Conclusions: Hospitalisation rates both for stroke and ACS were reduced during the COVID-19 outbreak in a country with strict social distancing measures, low COVID-19 incidence and low population mortality. Lack of triggers for stroke and ACS during social distancing/quarantining may explain these observations. However, medical care avoidance attitudes among cerebro/cardiovascular patients should be dissipated amidst the rising second COVID-19 wave. © 2020 European Academy of Neurolog

Micronutrient dietary intakes and their food sources in adults: the Hellenic National Nutrition and Health Survey (HNNHS)

Background: The present study aimed to assess micronutrient intake among Greek adults and to identify the main food sources that contribute to it. Methods: Food consumption data from 2389 participants in the Hellenic National Nutrition and Health Survey (HNNHS), collected with 24-h recalls, was used to calculate micronutrient intakes. Usual nutrient intake was estimated according to the National Cancer Institute method. Nutrient adequacy was estimated using the estimated average requirement (EAR) cut-point method, when available, or adequate intake otherwise. The probability approach was used to determine iron intake adequacy in females of reproductive age. Food group contribution for each nutrient assessed was derived to identify their main food sources. Results: Almost all individuals had vitamin D intake below EAR, whereas vitamins A, E, K and C, as well as potassium intake, were also insufficient in a considerable percentage of the population (>70% in most age groups). Calcium intake was substantially below the EAR for females aged >50 years and males >70 years; the same for magnesium in males >70 years. Furthermore, 50% of females, including those of reproductive age, had intake of folate below EAR. More than 50% of the population (to 79%) exceeded the upper tolerable limit for sodium (2300 mg day−1). Food contribution analysis revealed that most vitamins were derived from low-quality foods (i.e. fast-food). Conclusions: A significant proportion of adults residing in Greece have low nutrient intake and poor food selections. These results provide guidance to public health policy makers for developing strategies to improve the dietary quality in Greece. © 2021 The British Dietetic Association Ltd

The recalibrated HellenicSCORE based on newly derived risk factors from the Hellenic National Nutrition and Health Survey (HNNHS); the HellenicSCORE II

Background: Because of the increased burden of cardiovascular disease (CVD), country specific risk prediction models to forecast future CVD events and mortality are recommended, for primary prevention. The aim of this study was to recalibrate the HellenicSCORE, to accurately estimate the 10-year risk CVD mortality of Greek adults. Methods: Data from the Hellenic National Nutrition and Health Survey (HNNHS) were used (N = 1012; 37.9% males). Information on age, smoking, systolic blood pressure (SBP), and total blood cholesterol from adults >40 years of age were derived following validated health survey protocols. Individual scores were calculated using these data and beta-coefficients derived from ESC SCORE. Results: Both updated HellenicSCORE II charts had lower risk estimates compared to the older version and were closer to the ESC SCORE charts, particularly at the extremes. No significant age difference by sex was observed (mean 59.5 (SD 13.1) years in total) in the population. Women had a significant higher mean total cholesterol compared to men [212.9 (39.5) vs 204.6 (41.2) mg/dl, respectively; p = 0.0343], but smoking prevalence and mean SBP was significantly higher in men [p for all, <0.001]. The mean population HellenicSCORE II score level was between 5.6% (0.2) and 7.9% (3.2) depending on the chart used, with no significant sex differences. Conclusion: Although the HellenicSCORE II charts were lower, the mean population score was moderately high. This is of great importance because according to ESC guidelines, lifestyle intervention, and drug treatment should be based on an individuals’ total cardiovascular risk. © 2020 Hellenic Society of Cardiolog

Dietary patterns and cardiovascular disease in Greek adults: The Hellenic National Nutrition and Health Survey (HNNHS)

Background and aims: Empirically-derived dietary patterns have been shown to have both positive and adverse associations with cardiovascular disease (CVD). Yet, such associations remain unclear in the Greek population. The aim of this study was to investigate the association between empirically-derived dietary patterns and the presence of CVD and CVD-related medical conditions in a nationally representative sample of Greek adults. Methods and results: Adult participants (≥20 years old) of the Hellenic National Nutrition and Health Survey (HNNHS) were included (N = 3552; 41.2% men; 43.7 years, SD: 18.1). Dietary patterns were derived by principal component analysis using 24-h recall data. The presence of dyslipidemia (elevated cholesterol and/or triglycerides), hypertension, coronary heart disease, and total CVD, was defined according to the International Clinical Diagnosis (ICD)-10 codes. Odds ratios of CVD outcomes were estimated across dietary patterns using multivariable logistic regression analysis. Three dietary patterns -Traditional (proxy Mediterranean), Western, and Prudent-were identified explaining 16.5% of the total variance in consumption. Logistic regression analysis, adjusted for age, sex, total caloric intake, sociodemographic characteristics, and other CVD risk factors, showed an inverse association between the Traditional dietary pattern and CVD presence (OR: 0.53; 95% CI: 0.30–0.95), and a positive association between the Western pattern and dyslipidemia (1.52; 1.02–2.26). No association was found between the Prudent pattern and CVD outcomes. Conclusion: The variability of food intake combinations in the Greek population seem to be associated with the presence of CVD and CVD related conditions. Such findings are imperative for national monitoring and informed priority setting. © 2019 The Italian Society of Diabetology, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition, and the Department of Clinical Medicine and Surgery, Federico II Universit

Dietary patterns and lifestyle characteristics in adults: results from the Hellenic National Nutrition and Health Survey (HNNHS)

Objectives: The objective of this study was to identify and describe different dietary patterns in a nationally representative sample of Greek adults and to assess potential associations with lifestyle characteristics. Study design: This was a cross-sectional study. Methods: Dietary patterns were derived by principal component analysis using individual dietary data (24-h recall) of 3552 participants of the Hellenic National Nutrition and Health Survey (HNNHS). Analysis of variance and chi-squared test were used to determine the lifestyle characteristics of the participants following each pattern. Results: Three dietary patterns were identified explaining 16.5% of variance; a traditional pattern, loading positively on olive oil, non-starchy vegetables, and cheese; a Western pattern, loading positively on refined grains, processed meats, and animal fats; and a prudent pattern, loading positively on fruits, whole grains, and yoghurt and negatively on fast food. A fourth, snack-type pattern, loading positively on sweets, salty snacks, and nuts, was identified in women. Primary crude results revealed an association between dietary patterns and socio-economic status. In multivariate analysis, highest adherence to the prudent pattern was associated with higher protein and unsaturated fat intake and lower energy and saturated fat intake (all P ≤ 0.05); the Western and traditional patterns were associated with higher energy and total and saturated fat intake. The traditional pattern was additionally associated with higher monounsaturated fatty acids intake, whereas the Western pattern, with higher alcohol intake (all P ≤ 0.001). Conclusions: These findings are valuable for understanding the dietary behaviors of adults in Greece and enabling more focused public health policies for the promotion of healthier food behaviors in the future. © 2019 The Royal Society for Public Healt

Association of serum vitamin D status with dietary intake and sun exposure in adults

Background & aims: Serum 25(OH)D deficiency is becoming an epidemic. The aim was to assess vitamin D status of the adult Greek population in relation to intake, sun exposure and other factors, using data from the Hellenic National Nutrition and Health Survey (HNNHS). Methods: Data from 1084 adult participants (37.8% males) were analyzed. Vitamin D intake was assessed using 24-h recalls. Serum 25(OH)D concentration was evaluated and related to anthropometric measurements and other covariates including supplements used, by sex. Variables significantly associated with 25(OH)D < 20 ng/ml were assessed using simple and multiple logistic regression. Results: Median vitamin D intake from food was 1.23 mcg/day (0.60, 2.44), with 9.1% consuming supplements. Median serum 25(OH)D was 16.72 ng/ml, with no sex differences (P = 0.923). The odds of having 25(OH)D < 20 ng/ml significantly decreased with being very active (OR 0.55, 95% CI 0.35, 0.98), increasing length of sun exposure [1–3 h/day (OR 0.59, 95% CI 0.44, 0.80), >3 h/day (OR 0.36, 95% CI 0.24, 0.55)], and skin colour [light to medium skin (OR 0.47, 95% CI 0.24, 0.91), fairly dark skin colour (OR 0.34, 95% CI 0.17, 0.67) and dark or very dark skin colour (OR 0.34, 95% CI 0.15, 0.75)], compared to respective baseline levels. The odds significantly increased with obesity (OR 1.95, 95% CI 1.24, 3.08), and spring season of blood sample collection (OR 1.75, 95% CI 1.22, 2.50). Conclusions: Vitamin D deficiency is highly prevalent in Greek adults. Relevant public health policies are highly recommended, which could include vitamin D fortification. and suggestion for increased but safe sun exposure. © 2019 European Society for Clinical Nutrition and Metabolis
