Prevalence and Prognostic Factors of Stress Hyperglycemia in a Pediatric Population with Acute Illness in Greece-A Prospective Observational Study.

Background: stress hyperglycemia (SH) is a relatively frequent finding in pediatric patients. The purpose of this prospective observational study was to identify the prevalence of pediatric SH and its associated risk factors in Greece. Methods: A total of 1005 patients without diabetes who were admitted consecutively for acute illness in a Pediatric Emergency Department were included in the study. Medical history, anthropometric measurements, blood glucose levels, and the medication administered were recorded. A questionnaire was distributed to parents regarding medical and perinatal history and sociodemographic characteristics. Results: There were 72 cases of SH on admission (7.2%) and 39 (3.9%) during hospitalization. Mean age was 6.4 years; 50.3% were male. SH on admission was associated with oral corticosteroid therapy (21.1% vs. 4.7%, p < 0.001), inhaled corticosteroids (12.7% vs. 3%, p < 0.001), and inhaled ß2-agonists (30.6% vs. 10.7%, p < 0.001). In-hospital hyperglycemia was associated with oral corticosteroids (adjusted OR = 3.32), inhaled corticosteroids (OR = 10.03) and inhaled ß2-agonists (OR = 5.01). Children with asthma were 5.58 and 7.86 times more likely to present admission and in-hospital hyperglycemia, respectively. Conclusions: This is the first report of SH prevalence in pediatric patients in Greece. Asthma, corticosteroids, and ß2-agonists significantly increase the risk of SH. No parental factors seem to predispose to SH.

A study of the evolution of the third COVID-19 pandemic wave in the Athens metropolitan area, Greece, through two cross-sectional seroepidemiological surveys: March, June 2021.

We studied the third coronavirus disease 2019 (COVID-19) pandemic wave in Athens metropolitan area (3 738 901 inhabitants) through two seroepidemiological surveys. Persons presenting in 12 healthcare facilities across Athens in March and June 2021 were studied (764 and 901, respectively). Immunoglobulin G antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein were measured by a chemiluminescent microparticle immunoassay. In March the seroprevalence rate was 11.6%, meaning that 435 208 residents of Athens had evidence of immunity. The respective values in June were 55.7% and 2 082 568 residents. The highest seroprevalence rates attributed to SARS-CoV-2 infection were recorded in persons <18 years (16.3% in March and 31.6% in June), while immunity was mainly vaccine-induced in persons 18-64 years and >65 years. Infection-attributed immunity also increased in older-age groups. Wide ranges in seroprevalence rates were noted across areas in March and June. The highest seroprevalence rates were recorded in Piraeus (47.2%) and West Attica (37.5%). However, the highest increase (>5 times) occurred in Piraeus and the South Section of Athens, which are among the most densely populated areas in Athens. In both study periods, history of COVID-19 or febrile episode, and having a cohabitant with COVID-19 were associated with increased risk for seropositivity among unvaccinated persons (p values <0.001 for all). Residing in Piraeus, the South Section or West Attica was associated with increased risk for seropositivity in June (p values <0.001). Wide heterogeneity in seroprevalence rates was found across areas in Athens, which is mainly attributed to population density. The impact of population mobility and socioeconomic status should be explored.

Stress Hyperglycemia in Children and Adolescents as a Prognostic Indicator for the Development of Type 1 Diabetes Mellitus.

Hyperglycemia is a common manifestation in the course of severe disease and is the result of acute metabolic and hormonal changes associated with various factors such as trauma, stress, surgery, or infection. Numerous studies demonstrate the association of adverse clinical events with stress hyperglycemia. This article briefly describes the pathophysiological mechanisms which lead to hyperglycemia under stressful circumstances particularly in the pediatric and adolescent population. The importance of prevention of hyperglycemia, especially for children, is emphasized and the existing models for the prediction of diabetes are presented. The available studies on the association between stress hyperglycemia and progress to type 1 diabetes mellitus are presented, implying a possible role for stress hyperglycemia as part of a broader prognostic model for the prediction and prevention of overt disease in susceptible patients.

Effect of Infliximab and Adalimumab on Experimental Colitis Following Orally Supplemented Iron.

BACKGROUND: Orally administered iron can induce colonic inflammation in healthy animals and aggravate experimental colitis. AIM: To investigate the influence of the biologic agents infliximab and adalimumab on the severity of TNBS colitis following orally supplemented iron. MATERIALS-METHODS: 204 Wistar rats were allocated into 14 groups. Colitis was induced by TNBS. Iron was administered via a mouth catheter at a dose of 0.027, 0.3, and 3%/kg diet per day, respectively. Infliximab was subcutaneously administered on the 2nd and 6th day in a dose of 5 mg/kgBW, while adalimumab was administered on the 2nd day in a dose of 2 mg/kgBW. On the 8th day, all animals were euthanatized. Activity of colitis and extent of tissue damage were assessed histologically. Tissue Tumor Necrosis Factor-α (t-TNF-α) and malondialdehyde (t-MDA) were estimated. RESULTS: In normal rats both agents significantly worsen the degree of inflammation induced by moderate or high iron supplementation despite the disappearance of t-TNF-α, and reduction of t-MDA. In the groups of TNBS colitis and moderate or high iron administration, both agents again significantly worsen the degree of inflammation despite the significant reduction in the t-TNF-α and t-MDA. CONCLUSION: Adalimumab and infliximab do not ameliorate the inflammation in TNBS-induced colitis aggravated by orally administered iron. These findings might be clinically relevant in patients with active IBD under concurrent treatment with biologic agents and per oral iron.

Screening for colorectal cancer: the role of the primary care physician.

In recent years, the role of primary care physicians (PCPs) in the diagnosis and management of gastrointestinal disorders, including screening for colorectal cancer (CRC), has been recognized as very important. The available data indicate that PCPs are not adequately following CRC screening guidelines because a number of factors have been identified as significant barriers to the proper application of CRC screening guidelines. These factors include lack of time, patient reluctance, and challenges related to scheduling colonoscopy. Further positive engagement of PCPs with CRC screening is required to overcome these barriers and reach acceptable levels in screening rates. To meet the expectations of modern medicine, PCPs should not only be able to recommend occult blood testing or colonoscopy but also, under certain conditions, able to perform colonoscopy. In this review, the authors aim to provide the current knowledge of the role of PCPs in increasing the rate and successfully implementing a screening program for CRC by applying the relevant international guidelines.

Prevalence of Major Cardiovascular Risk Factors and Coronary Heart Disease in a Sample of Greek Adults: The Saronikos Study.

BACKGROUND: Comprehensive data regarding prevalence of coronary heart disease (CHD) and associated factors in different geographical regions are very important to our understanding of global distribution and evolution of CHD. The aim of this study was to assess the current prevalence of self-reported risk factors and CHD in Greek adult population. METHODS: A community-based cross-sectional study was conducted in May 2014, during an election day, among residents of Saronikos municipality (Attica region). Data were collected from face-to-face interviews. The study sample included 2636 subjects (men, 49.5%; mean age, 50.5; range 20-95 years), with similar age and sex distribution to the target population. RESULTS: The age-standardized prevalence rates of five major risk factors were as follows: type 2 diabetes 11.1%, hypercholesterolemia (cholesterol>240 mg/dl or using cholesterol-lowering medication) 23.8%, hypertension 27.2%, current smoking 38.9% and physical inactivity 43%. Of the participants, only 21% were free of any of these factors. Clustering of two to five risk factors was more frequent among persons aged 50 years and older as compared with younger ones (60% vs 27%, P=0.000). The age-adjusted prevalence of CHD was 6.3% (in men, 8.9%; in women, 3.8%) and that of myocardial infarction was 3.6% (in men, 5.2%; in women, 2.1%). According to multivariate analysis age, gender, education level, obesity, diabetes, hypercholesterolemia, hypertension and ever smoking were strongly associated with CHD. CONCLUSION: Classic risk factors are highly prevalent and frequently clustered, especially in adults aged 50 years and older. These findings raise concerns about future trends of already increased rates of CHD. Multifactorial and integrated population-based interventions need to be applied to reduce the burden of cardiovascular conditions.

Effect of mesalamine and prednisolone on TNBS experimental colitis, following various doses of orally administered iron.

BACKGROUND: Experimental data suggest that oral iron (I.) supplementation can worsen colitis in animals. AIM: To investigate the influence of various concentrations of orally administered I. in normal gut mucosa and mucosa of animals with TNBS colitis, as well as the influence of Mesalamine (M.) and Prednisolone (P.) on the severity of TNBS colitis following orally administered I. METHODS AND MATERIALS: 156 Wistar rats were allocated into 10 groups. Colitis was induced by TNBS. On the 8th day, all animals were euthanatized. Activity of colitis and extent of tissue damage were assessed histologically. The levels of tissue tumor necrosis factor- α (t-TNF- α ) and tissue malondialdehyde (t-MDA) were estimated in all animal groups. RESULTS: Moderate and high I. supplementation induced inflammation in the healthy colon and increased the activity of the experimentally induced TNBS colitis. Administration of M. on TNBS colitis following moderate iron supplementation (0.3 g/Kg diet) resulted in a significant improvement in the overall histological score as well as in two individual histological parameters. M. administration, however, did not significantly reduce the t-TNF- α levels (17.67 ± 4.92 versus 14.58 ± 5.71, P = 0.102), although it significantly reduced the t-MDA levels (5.79 ± 1.55 versus 3.67 ± 1.39, P = 0.000). Administration of M. on TNBS colitis following high iron supplementation (3.0 g/Kg diet) did not improve the overall histological score and the individual histological parameters, neither reduced the levels of t-TNF- α (16.57 ± 5.61 versus 14.65 ± 3.88, P = 0.296). However, M. significantly reduced the t-MDA levels (5.99 ± 1.37 versus 4.04 ± 1.41, P = 0.000). Administration of P. on TNBS colitis after moderate iron supplementation resulted in a significant improvement in the overall histological score as well as in three individual histological parameters. P. also resulted in a significant reduction in the t-TNF- α levels (17.67 ± 4.92 versus 12.64 ± 3.97, P = 0.003) and the t-MDA levels (5.79 ± 1.54 versus 3.47 ± 1.21, P = 0.001). Administration of P on TNBS colitis after high I. supplementation resulted in a significant improvement of the overall histological score and three individual histological parameters and significantly reduced the levels of t-TNF- α (16.6 ± 5.6 versus 11.85 ± 1.3, P = 0.001). CONCLUSION: I. can induce colonic inflammation and aggravate TNBS colitis. M. and P. can significantly improve the inflammatory process in the colonic mucosa in TNBS colitis aggravated by orally administered I. P. has a stable anti-TNF- α effect. These findings suggest that the harmful.

The role of primary care physicians in early diagnosis and treatment of chronic gastrointestinal diseases.

Chronic gastrointestinal disorders are a source of substantial morbidity, mortality, and cost. They are common in general practice, and the primary care physician (PCP) has a central role in the early detection and management of these problems. The need to make cost-effective diagnostic and treatment decisions, avoid unnecessary investigation and referral, provide long-term effective control of symptoms, and minimize the risk of complications constitute the main challenges that PCPs face. The literature review shows that, although best practice standards are available, a considerable number of PCPs do not routinely follow them. Low rates of colorectal cancer screening, suboptimal testing and treatment of Helicobacter pylori infection, inappropriate use of proton pump inhibitors, and the fact that most PCPs are still approaching the irritable bowel disease as a diagnosis of exclusion represent the main gaps between evidence-based guidelines and clinical practice. This manuscript points out that updating of knowledge and skills of PCPs via continuing medical education is the only way for better adherence with standards and improving quality of care for patients with gastrointestinal diseases.

Psychological factors and stress in inflammatory bowel disease.

The role of psychological distress and personality as predisposing factors for the development of inflammatory bowel disease (IBD) remains controversial. Attempts to investigate the role of psychological factors in IBD exhibited rather conflicting results. Among the studies concerning the effects of stress or depression on the course of IBD, the majority suggest that stress worsened IBD, the rest giving either negative or inconclusive results. However, application of strategies, including avoidance of coping and training patients in problem solving or emotion-oriented, could influence the course of IBD. Large controlled clinical trials are needed in order to clarify the impact of psychological interventions on the quality of life and the course of disease.

Prevalence of target organ damage in hypertensive subjects attending primary care: C.V.P.C. study (epidemiological cardio-vascular study in primary care).

BACKGROUND: Except for the established risk factors, presence of target organ damage has an important role in the treatment of hypertensive subjects. The aim of the present study was to estimate the prevalence of target organ damage in primary care subjects. METHODS: This multi-centre, cross-sectional survey of 115 primary care physicians recruited 1095 consecutive subjects with hypertension: 611 men (55.8%); and 484 women (44.2%). A detailed history for the presence of cardiovascular disease and a thorough clinical examination was performed to each subject. RESULTS: Of the total study population, 44.5% (n = 487) had target organ damage (33.0% had left ventricular hypertrophy, 21.8% increased carotid intima media thickness, 11.0% elevated plasma creatinine levels and 14.6% microalbuminuria). Target organ damage was more prevalent in males than in females (P = 0.05). In addition, males had more often increased carotid intima media thickness than females (P = 0.009). On the contrary, females had more often microalbuminuria (P = 0.06) than males. No differences were observed between the two genders regarding left ventricular hypertrophy (P = 0.35) and elevated plasma creatinine levels (P = 0.21). Logistic regression analysis showed associations between target organ damage and dyslipidemia (P < 0.001), presence of metabolic syndrome (P = 0.005), diabetes (P < 0.001) and coronary artery disease (P < 0.001). CONCLUSION: A significant proportion of hypertensive subjects in primary care had documented associated target organ damage, with left ventricular hypertrophy being the most prevalent target organ damage.

Self-medication with antibiotics in rural population in Greece: a cross-sectional multicenter study.

BACKGROUND: Self-medication is an important driver of antimicrobial overuse as well as a worldwide problem. The aim of the present study was to estimate the use of antibiotics, without medical prescription, in a sample of rural population presenting in primary care in southern Greece. METHODS: The study included data from 1,139 randomly selected adults (545 men/594 women, mean age +/- SD: 56.2 +/- 19.8 years), who visited the 6 rural Health Centres of southern Greece, between November 2009 and January 2010. The eligible participants were sought out on a one-to-one basis and asked to answer an anonymous questionnaire. RESULTS: Use of antibiotics within the past 12 months was reported by 888 participants (77.9%). 508 individuals (44.6%) reported that they had received antibiotics without medical prescription at least one time. The major source of self-medication was the pharmacy without prescription (76.2%). The antibiotics most frequently used for self-medication were amoxicillin (18.3%), amoxicillin/clavulanic acid (15.4%), cefaclor (9.7%), cefuroxim (7.9%), cefprozil (4.7%) and ciprofloxacin (2.3%). Fever (41.2%), common cold (32.0%) and sore throat (20.6%) were the most frequent indications for the use of self-medicated antibiotics. CONCLUSION: In Greece, despite the open and rapid access to primary care services, it appears that a high proportion of rural adult population use antibiotics without medical prescription preferably for fever and common cold.

Seasonal variation in fasting glucose and HbA1c in patients with type 2 diabetes.

Seasonal variations in fasting glucose and HbA1c levels in 638 diabetic patients (attending a primary care diabetic clinic during 2003-2007) were examined and found to be significantly higher in colder than in warmer months. Moreover, there were apparent peaks in fasting glucose levels after Christmas and Easter months. This study provides further evidence of monthly fluctuations in glycemic control, underscoring the need to consider seasonal/cultural effects when managing diabetic patients.

Prevalence of depressive symptoms among non insulin treated Greek type 2 diabetic subjects.

BACKGROUND: Depression is common among diabetic subjects. We conducted the present study to estimate the prevalence of depression in subjects with type 2 diabetes (T2D) in Greece. METHODS: The study sample consisted of 320 T2D subjects without overt macrovascular disease attending the diabetes outpatient clinic of our hospital, from June 2007 to December 2007. Depressive symptoms were measured using the 21-item Beck Depression Inventory, modified for use in diabetic subjects. RESULTS: Of the study subjects 107 (33.4%) reported elevated depressive symptoms. More women than men with diabetes reported symptoms of depression (48.4% vs. 12.7%, P < 0.001). In the female study group, depressive symptoms were correlated with HbA1c (P = 0.04), and duration of diabetes (P = 0.004). In the male study group, univariate linear regression analysis showed no significant relationships between depressive symptoms and the testing variables. CONCLUSION: The prevalence of depression in Greek T2D subjects is high. Diabetic female subjects showed increased levels of depressive symptoms compared with male subjects. Independent risk factors of depressive symptoms in diabetic female subjects were diabetes duration and glycemic control.

Granulomatous cheilitis associated with exacerbations of Crohn's disease: a case report.

INTRODUCTION: Crohn's disease is a disease involving the whole gastrointestinal tract from the mouth to the anus. Oral lesions are considered to be an important extraintestinal manifestation. Granulomatous cheilitis has been recognized as an early manifestation of Crohn's disease. It may follow, coincide with or precede the onset of Crohn's disease. The aim of this presentation is to describe a rare case of a patient with Crohn's disease in whom significant swelling of the lower lip not only preceded the diagnosis of Crohn's disease for two years, but it manifested as an early clinical index of the recurrence of the intestinal disease as well. CASE PRESENTATION: A man aged 25 was admitted in our department on August 1999 with chronic diarrhea and loss of weight. His bowel symptoms started in 1998 at the age of 24. However, two years previously (June 1996) he noticed a swelling of the lower lip, which contrasted significantly with the previously normal appearance of his mouth. A lip biopsy performed at that time was compatible with granulomatous cheilitis. Crohn's disease involving the terminal ileum and large bowel was diagnosed in 1998 and confirmed on the basis of colonoscopy, enteroclysis and histology findings of the small and large bowel. Conservative treatment resulted in clinical and laboratory improvement of the bowel symptoms and lip swelling. During the following years the disease was active with exacerbations and remissions of mild to moderate severity. The swelling of the lower lip occurred in parallel with the exacerbations of the bowel disease, returning to normal during periods of remission. CONCLUSION: Significant swelling of the lower lip due to granulomatous cheilitis could be the first manifestation of Crohn's disease, preceding intestinal symptoms. Exacerbation of the lip lesion could be an early clinical sign of a relapse of the underlying intestinal disease.

Rising prevalence of diabetes among Greek adults: findings from two consecutive surveys in the same target population.

AIMS: To examine trends in the prevalence of self-reported diabetes between 2002 and 2006 among urban adults in Greece. METHODS: Data were derived from two consecutive population-based surveys conducted in Salamis, during two election days (13 October 2002 and 15 October 2006). In both surveys was used the same selection procedure and data were collected using the same questionnaire, completed by almost the same team of interviewers. There were randomly selected 2805 adults (> or =20 years) in 2002 and 3478 in 2006, with similar age and sex distribution to the target population. RESULTS: The overall crude prevalence of diabetes increased significantly, from 245 (8.7%) in 2002 to 358 (10.3%) in 2006 (P=0.037). The age-adjusted prevalence of diabetes among adults was 8.2% (men, 8.5%; women, 7.8%) in 2002 and 9.5% (men, 9.7%; women, 9.3%) in 2006. These changes correspond to a total increasing rate of 16% (4% per year). At the same time, the age-adjusted prevalence of obesity increased from 17.9 to 21.1%, giving an increase of 18% (P<0.05); however, the prevalence of overweight did not increase (43.8-42.9%). CONCLUSIONS: Our findings show that the prevalence of diabetes is rising rapidly in the Greek population and appears to be increasing in parallel with prevalence of obesity.
