ETIKA I MEDICINA – IZAZOVI TEHNOLOŠKOG RAZVOJA

Ethics and morality define professional practice just as strongly as expertise. Principle-based ethics dominate ethical thinking in medicine, and much has to be done to help medical practitioners to think in ethical terms. Ethics is still too rare in medical thinking, and the advancement of medical technology is a challenge to the medical practice of today and tomorrow.Medicinska praksa jednako je određena etikom i moralom koliko i stručnošću. Etika utemeljena na moralnim načelima prevladava u medicinskim etičkim promišljanjima te valja učiniti još puno toga da se liječnicima u praksi pomogne promišljati etički. Etika je slabo zastupljena u medicinskim promišljanjima, a napredak medicinske tehnologije donosi nove izazove sadašnjoj i budućoj medicinskoj praksi

A theoretical insight into the photophysics of psoralen

Psoralen photophysics has been studied on quantum chemistry grounds using the multiconfigurational second-order perturbation method CASPT2. Absorption and emission spectra of the system have been rationalized by computing the energies and properties of the low-lying singlet and triplet excited states. The S1 ππ* state has been determined to be responsible of the lowest absorption and fluorescence bands and to initially carry the population in the photophysical processes related to the phototherapeutic properties of psoralen derivatives. The low-lying T1 ππ* state is, on the other hand, protagonist of the phosphorescence, and its prevalent role in the reactivity of psoralen is suggested to be related to the elongation of the pyrone ring C3–C4 bond, where the spin density is distributed on both carbon atoms. Analysis of energy gaps and spin-orbit coupling elements indicates that the efficient photophysical process leading to the population of the lowest triplet state does not take place at the Franck-Condon region but along the S1 relaxation [email protected] [email protected] [email protected]

PHYSICIAN IN THE CLASSIC PERIOD: EPIGRAPHIC TESTIMONIES

Medicine began to develop as scientific discipline in ancient Greece. Hippocratic medical schools spread all over the Mediterranean area and people who practiced medicine were reminded to posterity through epigraphic burial stones. Medical practice and personal skills were acknowledged in short sentences that are greatly helpful to understand past medicine and its pioneers. In this article selected burial stones dedicated to ancient physicians were examined to offer to scholars both of medicine and classical studies a deep insight into medical practice of the past

The healthcare professionals’ support towards organ donation. An analysis of current practices, predictors, and consent rates in Apulian hospitals

Introduction. The paper investigates the critical care staff’s support towards organ donation by analysing how their attitude, knowledge, confidence, engagement, and training can act as predictors of donation consent rates. Our study focused on hospitals in the Apulia Region, Italy.Material and methods. The study employs a quantitative methodology based on a survey of healthcare professionals. The rate of consent to organ and tissue donation at the hospital level, given as a ratio of the permissions received to the proposals performed, was extracted from GEDON software related to the year 2019 report. For each Apulian participating hospital, we calculated a median score for each of the five predictors (namely, attitude, knowledge, confidence, engagement, and training) and investigated the association with hospital consent rates.Results. The results highlight that the engagement of the intensive care units’ healthcare personnel stands as the only influential predictor of the consent rate.Discussion. In Italy’s Apulia Region, efforts are needed to increase consent rates for organ donation. Strategies should concentrate on continuous support, as well as specific training of hospital staff involved in the donation process

Sediment supply variation control on Lower Eocene delta sequences (Tremp Basin, Spain)

Sediment supply variations are often overlooked when interpreting depositional sequences, with most studies instead emphasizing changes in accommodation space. Here, we investigated a temporally well-constrained shallow-marine succession in the Tremp Basin to test the control of sediment supply variations on the development of deltaic sequences during the early Eocene. We analyzed the paleoenvironmental record (sedimentary facies and δ13Corg values) of the Morillo Limestone and the Castigaleu Formation (52.2−50.6 Ma). The first progradation of the deltaic system is marked by the abrupt appearance of thick delta-front sandstones and associated with the first negative carbon isotopic excursions (CIEs) in the measured δ13Corg record. Subsequent phases of progradation align with subsequent negative CIEs. Conversely, positive CIEs correspond to finer-grained, more-distal prodelta deposits. A series of hyperthermal events occurred during the deposition, globally identified as negative CIEs on δ13Ccarb reference curves, which we tentatively correlate with our δ13Corg data. We therefore suggest that during deposition of this Lower Eocene shallow-marine succession, the primary trigger behind sequence generation was the high-frequency climate-induced variation in sediment supply, specifically the hyperthermal events, rather than changes in accommodation. This linkage underscores the complex interactions between climate dynamics and sedimentary responses that shape the stratigraphic architecture of shallow-marine settings

Una Chiesa dell'impero salico. Piacenza nel secolo XI

Tra i secoli X e XI, nel passaggio dall’episcopato dell’italo-greco Giovanni Filagato a quello del lombardo Sigifredo, a Piacenza si radicava il culto di santa Giustina di Antiochia, destinato a divenire un importante elemento della locale identità ecclesiale. Gli anni del vescovo Sigifredo segnarono profondamente l’assetto cultuale e istituzionale della Chiesa piacentina, nella quale, com’è dimostrato, tra l’altro, dalla tradizione memoriale del monastero di S. Savino, erano attivi molteplici influssi riformatori. Solidamente incardinata nel quadro dell’impero salico e caratterizzata nei suoi connotati ecclesiali, politici e culturali dai tratti più tipici di quella particolare stagione della civiltà europea, Piacenza, sotto la guida energica del vescovo Dionigi, si avviava a svolgere un ruolo di primo piano nel drammatico conflitto che sarebbe divampato nella seconda metà del secolo XI
