First Data from the Prehistoric Site Complex of Cueva del Arco (Murcia, Spain)
The southern Iberian Peninsula is a key area for understanding the timing and patterns of the Middle-to-Upper Palaeolithic transition. Recently, the excavation and study of new sites have provided new insights on this topic. The aim of this paper is to introduce Cueva del Arco, a site complex featuring distinct caves and rock shelters. Cueva del Arco is located at a short distance from the Almadenes gorge (Cieza, Spain) and preserves both Middle and Upper Palaeolithic deposits and assemblages, as well as rock art. Despite being known since the 1990s for its Palaeolithic rock art, systematic fieldwork was never undertaken at the site until recently. We here report the first results of a research programme that includes the systematic excavation of several cavities belonging to the Cueva del Arco complex, focusing on the location and context of the site, its stratigraphy and chronology, and site formation. Research at the site is still ongoing, but preliminary results suggest that the data from Cueva del Arco will provide new clues to the current debate on the transition from Neanderthals to anatomically modern humans in southern Europe
Fontana Ranuccio (excavations 2019-2022) and Colle Marino (excavations 2020-2021): Middle Pleistocene chronostratigraphic evidence of the earliest inhabitants in the Anagni basin
Recent fieldwork of the Istituto Italiano di Paleontologia Umana in the Anagni basin (Latin Valley, southern Latium, central Italy) has provided new insights into the dynamics of human settlement and adaptation in this area during the Middle Pleistocene. This paper summarizes the still partially unpublished data on the chronostratigraphy of two important prehistoric sites: Fontana Ranuccio, dating from about 400,000 years ago, and Colle Marino, whose lithic industry has so far been attributed to an early stage of the Middle Pleistocene. At Fontana Ranuccio, stratigraphic studies highlighted the depositional dynamics and the processes involved in the formation of the archeological unit, consisting of partly reworked volcanic material, which can be now divided into distinct sub-units. At Colle Marino, a 35-meter-deep core drilling and an excavation campaign allowed us to verify the nature and provenance of lithic artifacts found on the surface in past decades. Radiometric analyses dated these artifacts from about 700,000 years ago
ERAS program adherence-institutionalization, major morbidity and anastomotic leakage after elective colorectal surgery: the iCral2 multicenter prospective study
Background Enhanced recovery after surgery (ERAS) programs influence morbidity rates and length of stay after colorectal surgery (CRS), and may also impact major complications and anastomotic leakage rates. A prospective multicenter observational study to investigate the interactions between ERAS program adherence and early outcomes after elective CRS was carried out. Methods Prospective enrolment of patients submitted to elective CRS with anastomosis in 18 months. Adherence to 21 items of ERAS program was measured upon explicit criteria in every case. After univariate analysis, independent predictors of primary endpoints [major morbidity (MM) and anastomotic leakage (AL) rates] were identified through logistic regression analyses including all significant variables, presenting odds ratios (OR). Results Institutional ERAS protocol was declared by 27 out of 38 (71.0%) participating centers. Median overall adherence to ERAS program items was 71.4%. Among 3830 patients included in the study, MM and AL rates were 4.7% and 4.2%, respectively. MM rates were independently influenced by intra- and/or postoperative blood transfusions (OR 7.79, 95% CI 5.46-11.10; p < 0.0001) and standard anesthesia protocol (OR 0.68, 95% CI 0.48-0.96; p = 0.028). AL rates were independently influenced by male gender (OR 1.48, 95% CI 1.06-2.07; p = 0.021), intra- and/or postoperative blood transfusions (OR 4.29, 95% CI 2.93-6.50; p < 0.0001) and non-standard resections (OR 1.49, 95% CI 1.01-2.22; p = 0.049). Conclusions This study disclosed wide room for improvement in compliance to several ERAS program items. It failed to detect any significant association between institutionalization and/or adherence rates to ERAS program with primary endpoints. These outcomes were independently influenced by gender, intra- and postoperative blood transfusions, non-standard resections, and standard anesthesia protocol
