Adults with Dental Erosion - Could This Be a Clinical Sign of Anorexia or Bulimia Nervosa? How is a Patient with Eating Disorders Approached?

Rhythms, requirements and standards of modern life have made the anxiety a common feature of most people. Along with stress, several other psychological problems increasingly appear and, unfortunately, critically affect young ages. 2 of the most common chronic mental disorders are anorexia nervosa and bulimia nervosa. Dentists are uniquely positioned because in their area of examination, signs of these diseases can be seen and then their symptoms can be discussed with patients. Nowadays, despite the fact that these diseases are on the rise, dentists do not know enough about them. Often, even if the knowledge is enough to diagnose the disease, they avoid doing it, because they try not to make their patients feel uncomfortable and lose them

Monitoring and performance evaluation of pilot vertical sunsurfae flow constructed wetlands treating olive mill wastewater

Περίληψη: Στη διπλωματική εργασία που παρατίθεται, διερευνάται η επεξεργασία λυμάτων ελαιοτριβείου (OMWW) από δύο πιλοτικούς τεχνητούς υγροβιότοπους κατακόρυφης ροής, με στόχο τη μείωση του οργανικού φορτίου και την απομάκρυνση θρεπτικών και άλλων ρύπων χωρίς περαιτέρω διεργασίες. Οι εφαρμοζόμενοι υγροβιότοποι τοποθετήθηκαν στο Πολυτεχνείο Κρήτης και πιο συγκεκριμένα στον περιβάλλοντα χώρο του θερμοκηπίου της σχολής ΧΗΜΗΠΕΡ. Οι δεξαμενές είναι φυτεμένες με κοινό καλάμι Phragmites australis (P. australis). Η πρώτη δεξαμενή πληρώθηκε αποκλειστικά με διογκωμένη άργιλο (leca), η απεικόνιση της οποίας θα γίνεται με την ονομασία L. Η δεύτερη είναι συνδυασμός leca, βιοεξανθρακώματος και ανακυκλωμένου πλαστικού (HDPE) και απεικονίζεται ως LPB. Το λύμα προήλθε από τριφασικό ελαιουργείου στην περιοχή των Περιβολιών (Χανιά), από τη φάση της απλής διοχέτευσης σε μία δεξαμενή (χωρίς εξάτμιση) όλου του υγρού κλάσματος που παρήχθη. Στην αρχή του πειράματος οι υγροβιότοποι ποτίζονταν με εκροή από υγροβιότοπους κατακόρυφης ροής, φυτεμένους επίσης με καλάμια Phragmites australis που για εισροή είχαν λύμα πρωτοβάθμιας επεξεργασίας από την Εγκατάσταση Επεξεργασίας Λυμάτων των Χανίων. Ακολουθήθηκε αυτή η διαδικασία για δύο εβδομάδες (Φεβρουάριος 2023) για να αναπτυχθούν τα καλάμια. Ύστερα, ως εισροή στις μονάδες χρησιμοποιήθηκε αραιωμένο (1:4) υγρό απόβλητο για 1 μήνα (τέλη Φλεβάρη – αρχές Μαρτίου) και εφαρμόστηκε αραίωση (1:8) μέχρι το τέλος του πειράματος. Το διάστημα ανά το οποίο γίνονταν φυσικοχημικές αναλύσεις στη δειγματοληψία εισροής και εκροής των μονάδων είναι οι 7-10 μέρες. Ειδικότερα, οι μετρήσεις αφορούσαν στον προσδιορισμό του pH, της αγωγιμότητας (EC), του BOD5, του COD, του TCU, των NO3--N, των NH4+-N, του TN, των PO43--P, του TP, των ολικών φαινολών και τέλος των TSS. Τα συμπεράσματα που προκύπτουν για την εγκυρότητα του σχεδιασμού και την αποτελεσματικότητα του, θα αξιολογηθούν από τις απομακρύνσεις των παραμέτρων που μετρήθηκαν. Για την μονάδα L επιτεύχθηκαν 67.37±16.28%, 85.2±15.0%, 74,0±17.0%, 81.16±18.07, 83.88±19.42, 51.7±24.1, 83.44±8.57%, 71.27±10.59% για COD, BOD5, TN, TP, PO43--P, TCU, ολικές φαινόλες, TSS αντίστοιχα. Για την μονάδα LPB επιτεύχθηκαν 68.64±18.31%, 84.8±15.8%, 71.1±19.5%, 78.16±19.01, 87.53±14.87, 36.3±31.0, 84.07±7.61%, 71.26±17.09% για COD, BOD5, TN, TP, PO43--P, TCU, ολικές φαινόλες, TSS αντίστοιχα. Όσον αφορά στα NH4+-N και NO3--N, ήταν σχεδόν μη ανιχνεύσιμα. Η υδραυλική αγωγιμότητα παρουσιάζει μία μικρή αύξηση και το pH από όξινο γίνεται αλκαλικό. Το βασικό συμπέρασμα που προέκυψε είναι ότι η leca, ως υλικό υποστρώματος, είναι μία αποτελεσματική εναλλακτική και πώς οι υγροβιότοποι είναι λύσεις για το πρόβλημα διάθεσης υγρών αποβλήτων ελαιουργείων.Summarization: In this thesis, the construction of two pilot units of artificial vertical flow wetlands as well as the experimental analysis of the inflows and outflows resulting from them, with the aim of reducing the organic load, nutrients and other pollutants from oil mill liquid waste. The pilot wetlands were placed at the Technical University of Crete and more specifically in the surrounding area of the greenhouse of the Chemical and Environmental Engineering school. The tanks are planted with common reed Phragmites australis (P. australis). The first tank was filled exclusively with expanded clay aggregate (leca), which will be depicted as L. The second is a combination of leca, biochar and recycled plastic (HDPE) and is depicted as LPB. The wastewater came from a three-phase oil mill in the area of Perivolia (Chania), from the phase of simple channeling into a closed tank (without evaporation) of all the liquid fraction produced. After the reeds were planted, the pilot plants were charged with the treated effluent of other artificial wetland systems that treated effluent from the Chania Wastewater Treatment. This process was followed for about a month to help the reeds grow. Then, diluted (1:4) olive mill wastewater was used as influent to the units for 1 month (March) and dilution (1:8) was applied until the end of the experiment. Sampling of the inflow and outflows of the units and corresponding physicochemical analyzes were performed on a weekly basis. In particular, the measurements concerned the determination of pH, conductivity (EC), BOD5, COD, colour (TCU), NO3-N, NH4-N, TN, PO4-P, TP, total phenols and TSS. The conclusions obtained from the monitoring of the units for this period serve to evaluate the design and the effectiveness of the treatment. For unit L, 67.4±16.3%, 85.2±15.0%, 74.0±17.0%, 81.2±18.1, 83.9±19.4, 51.7±24.1, 83.4±8.6%, 71.3±10.6% removals were achieved for COD, BOD5, TN, TP, PO4-P, TCU, total phenols, TSS respectively. For the LPB unit, 68.6±18.3%, 84.8±15.8%, 71.1±19.5%, 78.2±19.0, 87.5±14.9, 36.3±31.0, 84.1±7.6%, 71.3±17.1% were achieved for COD, BOD5, TN, TP, PO4-P, TCU, total phenols, TSS respectively. As for NH4-N and NO3-N, were almost undetectable. The hydraulic conductivity shows a slight increase and the pH changes from acidic to alkaline. The main conclusion reached is that leca, as a substrate material, is an effective alternative and constructed wetlands can be used to solve the disposal problem of oil mill wastewater

Possible adverse effects of immunotherapy in non-small cell lung cancer; treatment and follow-up of three cases

In the past decade novel agents are on the market for non-small cell lung cancer adenocarcinoma based on pharmacogenomics. The epidermal growth factor receptor mutation, anaplastic lymphoma kinase and programmed death-ligand 1 investigation is necessary in the everyday clinical practice for the oncologic patient. Immunotherapy is nowadays the novel therapy for advanced stage non-small cell lung cancer with two agents nivolumab and pembrolizumab. In the current case series we will present adverse effects from our centers and comment on the treatment and follow-up of the patients

Extensive testing and public health interventions for the control of covid-19 in the republic of cyprus between march and may 2020

Coronavirus disease 2019 (COVID-19) has significantly affected the well-being of individuals worldwide. We herein describe the epidemiology of COVID-19 in the Republic of Cyprus during the first epidemic wave (9 March–3 May 2020). We analyzed surveillance data from laboratory-confirmed cases, including targeted testing and population screening. Statistical analyses included logistic regression. During the surveillance period, 64,136 tests (7322.3 per 100,000) were performed, 873 COVID-19 cases were diagnosed, and 20 deaths were reported (2.3%). Health-care workers (HCWs) represented 21.4% of cases. Overall, 19.1% of cases received hospital care and 3.7% required admission to Intensive Care Units. Male sex (adjusted Odds Ratio (aOR): 3.04; 95% Confidence Interval (CI): 1.97–4.69), increasing age (aOR: 1.56; 95%CI: 1.36–1.79), symptoms at diagnosis (aOR: 6.05; 95%CI: 3.18–11.50), and underlying health conditions (aOR: 2.08; 95%CI: 1.31–3.31) were associated with hospitalization. For recovered cases, the median time from first to last second negative test was 21 days. Overall, 119 primary cases reported 616 close contacts, yielding a pooled secondary attack rate of 12% (95%CI: 9.6–14.8%). Three population-based screening projects, and two projects targeting employees and HCWs, involving 25,496 people, revealed 60 positive individuals (0.2%). Early implementation of interventions with targeted and expanded testing facilitated prompt outbreak control on the island
