- Abstract
INTRODUCTION Telehealth for COVID-19 patients is still limited. We aimed to assess the clinical effects of a home-based tele-rehabilitation exercise program following hospital discharge during the first lockdown in Greece, April to July 2020. METHODS A pre-and post-intervention design was applied in two stages. Firstly, patients were instructed to use a specially designed for COVID-19, e-book during four tele-health sessions. Afterwards, a 2-month home-based program consisted of self-practice exercise and one-hour supervised tele-rehabilitation exercise sessions every 10 days, was delivered. At baseline and at the end of the program, participants were interviewed about their physical, psychological status and quality of life (QoL) during the post-hospitalization period. The IPAQ-Gr, the HADS and the SF-36 questionnaires were used, respectively, and the participants were functionally assessed via teleconferences, using the 60 sec Sit to Stand Test (60secSTS), the Short Physical Performance Battery (SPPB) and the 3 min Step Test (3MST). RESULTS Seventy-four patients, median age 52.5 (IQR: 43–61) years were included at the first stage. From those, only 22 patients, mean ± SD age 50.1 ± 13.2 years completed the 2-month exercise program. The training program was well tolerated by all 22 patients. The mean number of unsupervised exercise sessions was 18.4 ± 3.5. No adverse effects were observed either during initial and follow-up assessment via tele-communication or during home-exercise sessions. Training improved significantly (p

- Abstract
Athens in antiquity as well today, included all the settlements in the wider Attica region. That is why its official name was “the Athens” (plural). Since prehistoric times, the city of Athens and the wider region of Attica did not contain many natural water sources so aquatic reserves were never adequate to meet the needs of residents, as these changed through time. The construction of aqueducts was part of a more organized effort to address the water needs of the Attica basin area since prehistoric times. In the ancient city, tens of small and large aqueducts were built to meet the city's needs for water. The hydraulic structures of Athens were mostly underground, for safety reasons. The water was channeled through aqueducts to fountains. Many aqueducts were built during the pre-Roman period and they were often works of leaders or other eminent citizens of ancient Athens. A key step in developing the city’s water infrastructure took place during the Roman occupation of Athens when the Hadrianic aqueduct and the Hadrianic reservoir were built. The project was a huge achievement for the time and was one of the longest tunnels worldwide during the Roman era Construction began in 125 AD and was completed in 140 AD. The Hadrianic aqueduct was underground with natural flow requiring a small and continuous slope along the aqueduct. Wells, communicating through the aqueduct, were placed at regular intervals. The main branch of the aqueduct - the central part of the Hadrianic, consists of the main tunnel, approximately 20 Km long, which starts from the foot of Mount Parnitha in the present day Olympic Village and ends up in the reservoir of Lycabettus, exploiting the water sources of Parnitha, Penteli and the Kifissos River. Gravity collected water from the water sources in the main tunnel and there was also the contribution of smaller aqueducts along the route. The secondary branches are composed of many transverse, which were designed to increase the water discharge capacity of the main aqueduct. The Hadrianic was a project of continuous multi source collecting groundwater along its path. It was constructed below the surface at a depth of 2.5 to 40 m depending on the upper aquifer of the Athens basin, which fed local wells, in order to collect groundwater from that aquifer, too. The Hadrianic stopped being maintained during the Ottoman occupation and returned into service after the liberation of the city until it was gradually abandoned after the construction of modern water resource projects. © 2016 Global NEST Printed in Greece.

In the present paper, the possibility to use dialkyl phosphate metabolites (DAPs) hair segmental analysis as a biomarker of past acute exposure to organophosphates is examined. Hair samples of four acute poisoning survivors were collected and segmental hair analysis was performed. The total hair samples were divided to 1 cm segments and analysed by gas chromatography-mass spectrometry (GC-MS) for the presence of four DAP metabolites, dimethyl phosphate (DMP), diethyl phosphate (DEP), diethyl thiophosphate (DETP) and diethyl dithiophosphate (DEDTP). Results were examined under the light of pesticide type and time of hair sample collection. Although DAPs were detected all along the hair shaft, higher concentrations (peaks) were detected in the segments proximate to the suicide period. It was also observed that the elevated concentrations of the present metabolites corresponded to the ones produced by the ingested parent compound. Conclusively, measurements of DAPs in the appropriate hair segments of OP-poisoned patients can be used for assessing past acute exposure to organophosphates in certain cases.

- Abstract
The COVID-19 pandemic has brought attention to a newly identified syndrome of multisystem inflammation. This potentially fatal complication of the disease was initially observed in children and later in adults. It affects primarily unvaccinated patients and may manifest within a timeframe of 2-12 weeks following infection. Soluble urokinase plasminogen activator receptor (suPAR), a novel biomarker, highlights the severity of inflammation and the degree of immune system activation. Herein, we report a case of a patient with multisystem inflammatory syndrome in adults (MIS-A) and markedly elevated suPAR levels, successfully treated with interleukin-1 (IL-1) receptor antagonist. A 59-year-old female was admitted to our hospital due to febrile illness (up to 40°C) with chills, vomiting, non-bloody diarrhea, and abdominal pain for four days prior to her admission. She tested positive for SARS-CoV-2 12 weeks before her presentation. During hospitalization, the patient deteriorated clinically with multiorgan involvement and hemodynamically instability, with concomitant markedly elevated inflammatory markers. Extensive workup with high suPAR levels led to post-COVID-19 MIS-A diagnosis, and treatment with dexamethasone and an interleukin-1 receptor antagonist (IL-1ra), anakinra, was administered. The subcutaneous injection of anakinra effectively and safely deterred MIS-A. Further research is needed to investigate the role of interleukin-1 inhibitors for the management of this potentially life-threatening condition., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

- Abstract
Left ventricular diastolic dysfunction (LVDD) is the predominant cardiac abnormality in cirrhosis. We investigated the association of LVDD with systemic inflammation and its impact on renal function, occurrence of hepatorenal syndrome (HRS) and survival in patients with cirrhosis and ascites. We prospectively enrolled 215 patients with cirrhosis and ascites. We evaluated the diagnosis and grading of LVDD by Doppler echocardiography, inflammatory markers, systemic hemodynamics, vasoactive factors, radioisotope-assessed renal function and blood flow, HRS development and liver-related mortality. LVDD was diagnosed in 142 (66%) patients [grade 2/3: n = 61 (43%)]. Serum lipopolysaccharide-binding protein (LBP), plasma renin activity (PRA) and glomerular filtration rate (GFR) were independently associated with the presence of grade 2/3 LVDD and the severity of diastolic dysfunction. Serum tumor necrosis factor-α, cardiac output and plasma noradrenaline were also independently associated with the presence of grade 2/3 LVDD. The diastolic function marker E / e ' was strongly correlated with serum LBP ( r = 0.731; P < 0.001), PRA ( r = 0.714; P < 0.001) and GFR ( r = -0.609; P < 0.001) among patients with LVDD. The 5-year risk of HRS development and death was significantly higher in patients with grade 2/3 LVDD compared to those with grade 1 (35.5 vs. 14.4%; P = 0.01 and 53.3 vs. 28.2%; P = 0.03, respectively). The occurrence and severity of LVDD in patients with cirrhosis and ascites is closely related to inflammatory activity. Advanced LVDD is associated with baseline circulatory and renal dysfunction, favoring HRS development, and increased mortality., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Background: Small intestinal bacterial overgrowth (SIBO) occurs frequently in patients with cirrhosis, particularly in those with ascites, and promotes the translocation of gut-derived bacterial products into the portal and systemic circulation. We investigated the effects of SIBO on systemic inflammatory activity, circulatory and renal function, and the degree of liver fibrosis in patients with cirrhosis and ascites., Methods: Eighty patients with cirrhosis and ascites were prospectively enrolled. SIBO was determined by lactulose breath test. Serum levels of lipopolysaccharide-binding protein (LBP), tumor necrosis factor-α, and interleukin-6, mean arterial pressure (MAP), cardiac output (CO) by echocardiography, systemic vascular resistance (SVR) as MAP/CO ratio, plasma renin activity (PRA), plasma aldosterone, radioisotope-assessed glomerular filtration rate (GFR), and liver stiffness by shear wave elastography were evaluated., Results: SIBO was detected in 58 patients (72.5%). Compared to patients without SIBO, those diagnosed with SIBO had significantly higher LBP levels (P<0.001), significantly lower MAP (P<0.001) and SVR (P<0.001), and significantly higher CO (P=0.002) and PRA (P<0.001). Patients with SIBO had significantly lower GFR (P=0.02) and higher liver stiffness (P=0.04) compared to those without SIBO. The presence of SIBO was independently associated with LBP (P=0.007) and PRA (P=0.01). Among patients with SIBO, peak breath hydrogen concentration was significantly correlated with serum LBP (P<0.001), MAP (P<0.001), CO (P=0.008), SVR (P=0.001), PRA (P=0.005), plasma aldosterone (P<0.001), GFR (P<0.001), and liver stiffness (P=0.004)., Conclusion: SIBO in patients with cirrhosis and ascites may predispose to greater systemic inflammation, circulatory and renal dysfunction, and more advanced liver fibrosis., Competing Interests: Conflict of Interest: None, (Copyright: © Hellenic Society of Gastroenterology.)

- Abstract
Background and Aim: The prevalence of alcohol-associated cirrhosis is increasing. In this respect, we investigated the long-term impact of non-abstinence on the clinical course of alcohol-associated cirrhosis., Methods: We retrospectively evaluated 440 patients with alcohol-associated cirrhosis (compensated cirrhosis: n = 190; decompensated cirrhosis: n = 250) diagnosed between January 2000 and July 2017 who consumed alcohol until diagnosis of cirrhosis. We assessed liver-related outcomes including first and further decompensating events (ascites, variceal bleeding, and hepatic encephalopathy), and death in relation to continued alcohol use., Results: Overall, 53.6% of patients remained abstinent (compensated cirrhosis: 57.9%; decompensated cirrhosis: 50.4%). Non-abstinent versus abstinent patients with compensated cirrhosis and decompensated cirrhosis showed significantly higher 5-year probability of first decompensation (80.2% vs. 36.8%; P < 0.001) and further decompensation (87.9% vs. 20.6%; P < 0.001), respectively. Five-year survival was substantially lower among non-abstinent patients with compensated cirrhosis (45.9% vs. 90.7%; P < 0.001) and decompensated cirrhosis (22.9% vs. 73.8%; P < 0.001) compared to abstinent. Non-abstinent versus abstinent patients of the total cohort showed an exceedingly lower 5-year survival (32.2% vs. 82.4%; P < 0.001). Prolonged abstinence (≥2 years) was required to influence outcomes. Non-abstinence independently predicted mortality in the total cohort (hazard ratio [HR] 3.371; confidence interval [CI]: 2.388-4.882; P < 0.001) along with the Child-Pugh class (HR: 4.453; CI: 2.907-6.823; P < 0.001) and higher age (HR: 1.023; CI: 1.007-1.039; P = 0.005)., Conclusion: Liver-related outcomes are worse among non-abstinent patients with alcohol- associated cirrhosis prompting urgent interventions ensuring abstinence., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Background and Aims: The definition of relative adrenal insufficiency (RAI) in patients with cirrhosis remains controversial. We investigated the serum and salivary cortisol (SalC) response after low-dose and standard-dose Synacthen test in patients with stable cirrhosis and ascites., Methods: Ninety-five cirrhotic patients with ascites were prospectively evaluated from January 2014 to January 2018. Low-dose [adrenocorticotrophic hormone (ACTH): 1 μg] and standard-dose (ACTH: 250 μg) Synacthen test were successively performed. Paired serum total and saliva cortisol were taken at baseline, 30 min (low-dose test) and 60 min (standard-dose test). Salivary and Δserum total cortisol criteria included post-ACTH SalC < 12.7 ng/ml and/or SalC increase <3 ng/ml and serum total cortisol increase <9 μg/dl, respectively., Results: The prevalence of RAI varied according to the definition used. SalC-defined RAI was significantly more common after low-dose than standard-dose test (54.7% vs. 20%; P < 0.001). Δserum total cortisol-defined RAI was also significantly more frequent after low-dose than standard-dose test (66.3% vs. 24.2%; P < 0.001). Considering low-dose test/SalC criteria as reference diagnostic criteria, standard-dose/salivary and Δserum total cortisol criteria showed low specificity for RAI diagnosis (43.9% and 52.7%, respectively). Survival probability was significantly lower in patients with low-dose test/SalC-defined RAI compared to those without (53.8% vs. 79.1%; P = 0.01). SalC-defined RAI after low-dose test was significantly more common than that defined after standard-dose test (72.7% vs. 30.3%; P < 0.001) among patients who died., Conclusion: Low-dose test/SalC definition can identify RAI in about half of patients with stable cirrhosis and ascites and is associated with increased mortality., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: In recent years, concerns have been raised on the potential adverse effects of nonselective beta-blockers, and particularly carvedilol, on renal perfusion and survival in decompensated cirrhosis with ascites. We investigated the long-term impact of converting propranolol to carvedilol on systemic hemodynamics and renal function, and on the outcome of patients with stable cirrhosis and grade II/III nonrefractory ascites., Patients and Methods: Ninety-six patients treated with propranolol for esophageal varices' bleeding prophylaxis were prospectively evaluated. These patients were randomized in a 2:1 ratio to switch to carvedilol at 12.5 mg/d (CARVE group; n=64) or continue propranolol (PROPRA group; n=32). Systemic vascular resistance, vasoactive factors, glomerular filtration rate, and renal blood flow were evaluated at baseline before switching to carvedilol and after 6 and 12 months. Further decompensation and survival were evaluated at 2 years., Results: During a 12-month follow-up, carvedilol induced an ongoing improvement of systemic vascular resistance (1372±34 vs. 1254±33 dynes/c/cm5; P=0.02) along with significant decreases in plasma renin activity (4.05±0.66 vs. 6.57±0.98 ng/mL/h; P=0.01) and serum noradrenaline (76.7±8.2 vs. 101.9±10.5 pg/mL; P=0.03) and significant improvement of glomerular filtration rate (87.3±2.7 vs. 78.7±2.3 mL/min; P=0.03) and renal blood flow (703±17 vs. 631±12 mL/min; P=0.03); no significant effects were noted in the PROPRA group. The 2-year occurrence of further decompensation was significantly lower in the CARVE group than in the PROPRA group (10.5% vs. 35.9%; P=0.003); survival at 2 years was significantly higher in the CARVE group (86% vs. 64.1%; P=0.01, respectively)., Conclusion: Carvedilol at the dose of 12.5 mg/d should be the nonselective beta-blocker treatment of choice in patients with cirrhosis and nonrefractory ascites, as it improves renal perfusion and outcome., (Copyright © 2020 Wolters Kluwer Health, Inc.

- Abstract
The aim of this study was to evaluate the potential use of micronized whole wheat flours in breadmaking. The micronization process was achieved by a jet mill and flours (JF) of particle size, ranged from 17 to 84 μm, were used. According to the particle size of the JF, the amount of water added to dough changed and ranged from 77 to 84% as it was calculated in farinograph experiments. JF breads had higher bread yield, firmer crumb, higher elasticity, lower porosity and darker bread color compared to control whole wheat bread. Overall a lower particle size of JF resulted in a close structure of bread. According to sensory evaluation, difference among samples was difficult to perceive. During storage JF bread presented lower limiting firmness potential. After all, there is evidence that jet milled flour determined bread physical characteristics and further storage stability., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

- Abstract
Background: The aim of this study was to predict the occurrence of hepatorenal syndrome (HRS) and death in patients with advanced cirrhosis and ascites., Patients and Methods: We retrospectively evaluated 2-year data of 78 patients with cirrhosis and ascites (Child-Pugh B/C: 45/43). The mean arterial pressure (MAP) and cardiac output (CO) were measured in all patients just before administration of 2 mg of terlipressin and 30 min later. Systemic vascular resistance (SVR) was calculated as MAP/CO. ΔMAP, and ΔCO, and ΔSVR were defined as the percentage change of MAP, CO, and SVR, respectively, after terlipressin injection. Plasma renin activity (PRA) and plasma aldosterone were evaluated at baseline. Two multivariate models were used: one excluding (model 1) and one including (model 2) the Model of End-stage Liver Disease score., Results: Higher ΔSVR, Model of End-stage Liver Disease score, and PRA were related independently to the severity of cirrhosis. Independent predictors of HRS at 12 and 24 months were ΔSVR (models 1/2: P=0.008/0.01 and 0.01/0.02, respectively), ΔCO (models 1/2: P=0.01/0.03 and 0.03/0.04, respectively), and PRA (models 1/2: P=0.04 and model 1: P=0.04, respectively). ΔSVR at 12 and 24 months (models 1/2: P=0.005/0.01 and 0.01/0.03, respectively) and ΔCO at 24 months (models 1/2: P=0.02/0.01, respectively) were related independently to survival. Patient groups with significantly higher probability of HRS and mortality were identified by certain cutoffs of ΔSVR (20.6 and 22.8%, respectively) and ΔCO (-10.6 and -11.8%, respectively). ΔSVR and ΔCO independently predicted survival in patients with the most advanced cirrhosis and infection-related survival., Conclusion: An increase in SVR by at least 20% and a decrease in CO at least 10% in response to terlipressin could predict HRS and mortality in patients with advanced cirrhosis.

- Abstract
Bullying can be defined as when one (or more) individual engages in aggressive behaviour against another individual who seem to be unable to defend himself. This action is intentional and persistent and creates great distress and fear. There are not specific statistics in Greece but recent researches from EKKE showed that one out of four children in Athens have been bullied physically. Bullying is a multifaceted and complex problem. Modern psychological perspectives emphasize that aggressive and violent behaviours are learned responses to frustration. Learning occurs by observing models of such behaviour in the family, in the neighbourhood, in school. Ignoring the problem gives a bad example. Prevention and intervention strategies should include the family, the school personnel and the children. Bullying has negative effects on the physical and mental health of the child and it can also cost his life, some kids commit suicide. Therefore intervention strategies need to develop in the communities. The aim is to create a -physically and psychologically- safe environment.
