Vermetid reefs in the Mediterranean Sea as archives of sea-level and surface temperature changes

Vermetid reefs are among the most important bioconstructions in the Mediterranean Sea, with a distribution restricted to the warmest part of the basin. Their structure, and vertical and geographical distribution make them good biological indicators of changes in sea level and sea-surface temperature over the last two millennia

Sea level rise in the Mediterranean Sea: High resolution constraints from vermetid reefs

The Mediterranean Sea (MS), is extremely sensitive to rising sea-levels (SL) as attested by drowned archeological remains from the Roman Period. Due to theabsence of coral reefs, evidence for recent and Holocene SL change has so far mainly been restricted to coastal cores archeological remains and submerged speleothem deposits. Vermetid reefs are an extremely sensitive high resolution carbonate archive and they are mainly formed in the lower intertidal zone by gregarious and sessile gastropods belonging to the genus Dendropoma (family Vermetidae). Since their interval of growth is restricted to the tidal zone, they can be used as precise SL proxies (about ±0.1 m in lowrange tidal areas). Here, we report new SL data covering two time-windows: between 2,380 and 1,520 years cal BP and during the last 300 yrs. These data have been obtained from two quasi-stable areas of the Western MS: S. Vito Lo Capo (N Sicily, Italy)and Cabo de Gata(SE Spain), opening new perspectives to understand the response of the global changes on this semienclosed basin

Rilevazione nazionale in tema di formazione specifica di medicina generale in Italia

Physicians have to get a \u201cspecific\u201d diploma attending a threeyear training course provided by each regional health service in order to practice as General Practitioners in Italy. In the last years, there has been an ongoing debate about the need to evolve the specific regional courses into integrated specialization training courses, organized and managed by universities with the contribution of regional health services. The Italian Junior Doctors Association and the Giotto Movement carried out a national survey with the aim to identify strengths and weaknesses of the specific regional training courses. Three-hundred-two junior General Practitioners in training (61,2% females) answered to a web administered questionnaire. Only about half of the recruited trainees has defined as at least \u201csufficient\u201d the training provided by the regional courses. The survey documented in the Italian General Practitioners trainees the need to satisfy an educational demand in order to implement their primary care and general practice skills. In conclusion, this cross-sectional study provided sufficient evidences supporting the evolution of the regional training courses into general practice and primary care specialization schools

Comparación de dos morfotipos de Zuccagnia punctata (Fabaceae) en los Valles Calchaquíes en Argentina

Zuccagnia punctata Cav. (Fabaceae) is a medicinal aromatic shrub, a monotypic species with a wide distribution in Argentina. Two morphotypes were found in Valles Calchaquíes, one with yellow fruits (YF) and other with red-brown fruits (RBF). The color of fruits varies between individuals within a population, with some plants producing red-brown fruits and other yellow fruits. The cytogenetic differentiation was determined using root tips. Leaves and fruits were used to analyze chemical composition by HPLC-DAD and HPLC/MS/MS. The number of chromosome (2n = 24) was reported for the first time for the genus. The yellow fruits and red-brown fruits morphotypes showed different karyotypes. The compounds common to both morphotypes were identified in leaves and fruits as chalcones, compounds with biological activity and biomarkers used for quality control of Z. punctata products. Two chemotypes related to the color of the fruits, were detected. An anthocyanin, cyanidin 3-glucoside was found in red-brown fruits (4.75 mg.g-1 fruits) but not in yellow fruits. These is the first report on yellow fruits morphotype of Z. punctata and on presence of anthocyanins in Z. punctata red-brown fruits morphotype. This work contributes to the knowledge of Z. punctata, a native plant from Argentina with high economic potential to promote the regional economy.Zuccagnia punctata Cav. (Fabaceae) es un arbusto aromático medicinal monotípico con amplia distribución en Argentina. En los Valles Calchaquíes se encontraron dos morfotipos, uno con frutos amarillos y otro con frutos marrón rojizo. El color de los frutos varía entre individuos de una misma población, observándose plantas que tienen frutos de color marrón rojizo y otras con frutos de color amarillo. La diferenciación citogenética fue determinada usando puntas de raíces mientras que las hojas y frutos se usaron para analizar la composición química por HPLC-DAD y HPLC/MS/MS. Se informó por primera vez el número cromosómico (2n = 24) para el género Zuccagnia. Ambos morfotipos mostraron diferentes cariotipos. Se identificaron chalconas como compuestos comunes en las hojas y frutos de ambos morfotipos. Las chalconas son consideradas biomarcadores en el control de calidad de productos a base de Z. punctata. Se detectaron dos quimiotipos relacionados al color de los frutos. La antocianina, cianidin 3-glucosido se encontró en frutos marrón rojizos (4.75 mg.g-1 fruto) pero no en frutos amarillos. Este es el primer informe sobre un morfotipo de Z. punctata con frutos amarillos y sobre la presencia de antocianinas en el morfotipo de frutos rojos. Este trabajo contribuye al conocimiento de Z. punctata, una planta nativa de Argentina con alto potencial económico para promover el desarrollo regional.Fil: Álvarez, María A..

Motivational aspects and level of satisfaction of Italian junior doctors with regard to knowledge and skills acquired attending specific general practice training courses. A national web survey

The demographic and epidemiological transitions resulted in a pressing need to reformulate the health workforce demand and to revise pre-and post-graduate training to prepare the medical profiles to meet the new health needs focused on chronic diseases. The Italian Junior Doctors Association and the Giotto Movement carried out a web survey to identify the motivational aspects and the level of satisfaction of Italian junior doctors regarding knowledge and skills acquired after attending the General Practitioners\u2019 specific training (GP-ST). Three-hundred-forty-seven General Practitioners (GPs), 302 trainees and 45 newly qualified trainees answered a web questionnaire. Significant differences (p-value= 0.018) were documented between the two groups regarding the level of satisfaction on the GP-ST. The analysis by geographic macro-areas of the answers given by the 302 trainees showed a heterogeneous level of overall satisfaction (p-value= 0.005). In conclusion, the evidence provided by this cross-sectional study support the proposal to evolve the GP-ST regional courses into general practice and primary care specialization schools

Assessing vermetid reefs as indicators of past sea levels in the Mediterranean

The endemic Mediterranean reef building vermetid gastropods Dendropoma petraeum complex (Dendropoma spp) and Vermetus triquetrus develop bio-constructions (rims) on rocky shorelines at about Mean Sea Level (MSL) and are therefore commonly used as relative sea-level (RSL) markers. In this study, we use elevations and age data of vermetid reefs to (1) re-assess the vertical uncertainties of these biological RSL indicators, and (2) evaluate the vertical growth rates along a Mediterranean east-west transect, in attempt to explain the differences found in both growth rates and uncertainties. In Israel, Differential Global Positioning System (DGPS) and laser measurements relative to the local datum show that the reef surfaces mainly occupy the upper intertidal zone with variations in elevation from +0.51 ± 0.07 m to +0.13 ± 0.05 m along the coast. However, in specific sites the vertical uncertainty exceeds the tidal range. In some places the local vermetid species D. anguliferum and V. triquetrus appear to alternate along the vertical rim profiles. This study documents a spatial variability of vertical growth rates, ranging from ~1 mm yr−1 in Israel and Crete, to ~0.1–0.2 mm yr−1 in NW Sicily and Spain. The order of magnitude of the difference in growth rates correlates with the east-west spatial thermal gradient of Sea-Surface Temperature (SST). Preferential skeleton deposition of D. petraeum and V. triquetrus measured by growth axis δ18O analysis shows that most calcification occurs at SST above the mean annual value. These findings indicate that vermetid reefs are a site-specific RSL indicator, displaying various vertical uncertainties and inner-structure complexities. Local data on the indicative range of vermetids are required when reconstructing relative sea-level changes using fossil vermetids

Italian good practice recommendations on management of persons with Long-COVID

A significant number of people, following acute SARS-CoV-2 infection, report persistent symptoms or new symptoms that are sustained over time, often affecting different body systems. This condition, commonly referred to as Long-COVID, requires a complex clinical management. In Italy new health facilities specifically dedicated to the diagnosis and care of Long-COVID were implemented. However, the activity of these clinical centers is highly heterogeneous, with wide variation in the type of services provided, specialistic expertise and, ultimately, in the clinical care provided. Recommendations for a uniform management of Long-COVID were therefore needed. Professionals from different disciplines (including general practitioners, specialists in respiratory diseases, infectious diseases, internal medicine, geriatrics, cardiology, neurology, pediatrics, and odontostomatology) were invited to participate, together with a patient representative, in a multidisciplinary Panel appointed to draft Good Practices on clinical management of Long-COVID. The Panel, after extensive literature review, issued recommendations on 3 thematic areas: access to Long-COVID services, clinical evaluation, and organization of the services. The Panel highlighted the importance of providing integrated multidisciplinary care in the management of patients after SARS-CoV-2 infection, and agreed that a multidisciplinary service, one-stop clinic approach could avoid multiple referrals and reduce the number of appointments. In areas where multidisciplinary services are not available, services may be provided through integrated and coordinated primary, community, rehabilitation and mental health services. Management should be adapted according to the patient's needs and should promptly address possible life-threatening complications. The present recommendations could provide guidance and support in standardizing the care provided to Long-COVID patients

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at sNN\sqrt{s_{\rm NN}} = 2.76 TeV

The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.Comment: 17 pages, 5 captioned figures, 1 table, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/388
