Palaeoenvironment, Settlement, and Land Use in the Late Neolithic—Bronze Age Site of Colombare di Negrar di Valpolicella (N Italy, On-Site)

Palynological and archaeobotanical analyses have been carried out as part of the interdisciplinary project of Colombare di Negrar, a prehistoric site in the Lessini Mountains (northern Italy). The palaeoenvironmental and economic reconstruction from the Late Neolithic to the beginning of the Early Bronze Age was based on 16 pollen samples and three samples of macroremains taken from two contiguous trenches. The landscape reconstruction shows the presence of natural clearings in the wood. Forest cover was characterised by oak wood, with Ulmus and Tilia. The intermediate morphology of size and exine of Tilia cordata/platyphyllos pollen may be regarded as the first palynological evidence of lime hybrids in palaeorecords. Hygrophilous trees and Vitis vinifera testify to the presence of riparian forests and moist soils. Among trees supplying fruits, in addition to the grapevine, hazelnut (Corylus avellana) and walnut (Juglans regia) were present. A mixed economy based on animal breeding and cultivation of cereals (Hordeum vulgare, Triticum monococcum, T. dicoccum, T. timopheevii) emerged from the data. The combined analysis of pollen and plant macroremains suggests that different activities were carried out simultaneously in Colombare and a relationship between natural resources and the socio-economic and cultural evolution of the territory

Compliance with gestational weight gain recommendations in a cross-sectional study of term pregnancies — how far reality falls from the standard?

Objectives: During pregnancy, two aspects are critical in the context of adverse perinatal outcomes (APO): preconception obesity and gestational weight gain. This study aimed to assess compliance with the 2009 IOM guidelines, compare GWG with and without correcting for gestation duration, and observe the relationship between pre-pregnancy BMI and GWG and neonatal birth weight. Material and methods: This is a cross-sectional study conducted from 2015-2018 at the St. Sophia's Specialist Hospital in Warsaw, Poland. Self-reported pre-pregnancy and predelivery weight were collected. Results: The presented data set amounts to 7820 records. Analysis of weight gain compliance with IOM recommendations showed that only 41–44% (depending on the calculation method) of women had weight gain in accordance with IOM guidelines (22–23% — below; 33–37% — above). Overweight and obese women with diabetes are more likely to comply with IOM than women without diabetes. In contrast, women with normal-weight and underweight with diabetes are less likely to achieve IOM weight gain in pregnancy than women without diabetes. Women who have GWG below recommendations significantly more often gave birth to SGA neonates, and women who exceeded GWG standards significantly more often gave birth to LGA neonates. Conclusions: Less than half of women had GWG within the recommended norms. Statistically significant differences were found in methods of calculation of GWG, but it was not found clinically significant. Correction for pregnancy duration when calculating GWG reclassifies two percent of patients. We underestimate the risk of crossing the line between overweight and obesity during pregnancy

MGMT methylation in diffuse large B-cell lymphoma: validation of quantitative methylation-specific PCR and comparison with MGMT protein expression.

AIMS: (1) To validate a quantitative real time methylation specific PCR assay (MethyLight) for the detection of O6-methylguanine-DNA methyltransferase (MGMT) gene methylation status (MS) in diffuse large B-cell lymphoma (DLBCL). (2) To determine the immunohistochemical (IHC) expression of the MGMT protein and correlate it with MS. Both IHC and MethyLight results were compared with patient's outcome. METHODS: 71 patients with primary nodal DLBCL were studied. MGMT immunoreactivity was detected using a specific monoclonal antibody. The MS of MGMT gene was analysed in 52/71 DLBCL using MethyLight. A selected subset of 40 DLBCL was also analysed using qualitative methylation-specific PCR (MSP). Statistical analysis of overall survival (OS), lymphoma-specific survival (LSS) and progression free survival (PFS) was performed according to IHC and MS results. RESULTS: 19/71 DLBCLs (27%) were MGMT-negative at IHC; all were analysed, together with 33/52 MGMT-positive DLBCLs. MethyLight showed a better performance than MSP. There was a good correlation between the presence of MGMT expression and the unmethylated status; the absence of IHC expression was poorly correlated with the presence of methylation. Better OS, LSS and PFS was found in DLBCLs with MGMT gene methylation. DLBCLs not expressing MGMT at IHC showed a longer PFS. CONCLUSIONS: The quantitative real-time methylation-specific PCR assay for the detection of MGMT gene hypermethylation has been validated for the first time in DLBCL. Immunohistochemistry seems to represent an useful preliminary test to identify unmethylated cases; MS analysis may be performed in non-immunoreactive cases to identify truly methylated DLBCLs, which bear a better prognosis

The Association between Postpartum Pelvic Girdle Pain and Pelvic Floor Muscle Function, Diastasis Recti and Psychological Factors—A Matched Case-Control Study

There is uncertainty regarding the association between abdominal morphology, pelvic floor function, and psychological factors in women with postpartum pelvic girdle pain (PGP). The aim of this case-control study was to evaluate the differences between women with and without persistent PGP regarding pelvic floor function, diastasis recti, and psychological factors 6–24 weeks postpartum. Pelvic floor manometry, palpation examination of abdominal muscles, the International Consultation on Incontinence Questionnaire Short Form, The Depression, Anxiety and Stress Scale—21, and the Pain Catastrophizing Scale were used. The PGP group presented with lower vaginal resting pressure (p < 0.001), more tenderness (p = 0.018) and impaired voluntary activation of pelvic floor muscles (p ≤ 0.001). Women with pain also had more distortion on the level of the anterior abdominal wall (p = 0.001) and more severe diastasis recti (p = 0.046) when compared to pain-free controls. Lower vaginal resting pressure was the strongest factor explaining PGP (OR 0.702, 95%CI 0.502–0.981). There were no differences in terms of the pelvic floor strength, endurance, severity of urinary incontinence and reported distress between the groups. Women with PGP 6–24 weeks postpartum differ in pelvic floor and abdominal muscle function from the pain-free controls. Vaginal resting pressure may be an important factor in pelvic girdle pain shortly postpartum. Further studies are needed to see a trend in changes over time

Seeds/fruits data from the "Vasca Superiore di Noceto", an artificial mire of the Bronze Age in the Po Plain (N Italy)

The Noceto wooden basin is an huge structure (12x7 m and about 3,5 m deep) situated in the central Po plain near Parma. Discovered in 2004 and it was studied through several archaeological fields from Soprintendenza dei Beni Archeologici dell’Emilia-Romagna with the collaboration of University of Milan (Bernabò Brea and Cremaschi 2009). This basin was built from the terramara's inhabitants of Noceto during Middle Bronze Age (1650-1350 BC) and was originally filled with water. The waterlogged anoxic deposits and the fill characteristics preserved the structure and many wooden objects. Most remarkable are the remains of four ploughs deposited at the corners of the basin. Furthermore, more than 150 whole or fragmented ceramic vases were found, together with miniature vases and figurines. The position of the structure, the type of depositions and their distribution within the basin suggest ritual activities probably linked to agrarian and water cult (Bernabò Brea and Cremaschi 2009). This condition allowed the good conservation of seeds and fruit remains. ... Ritual practices from Noceto wooden basin are suggested from the different type of evidences recovered. Also, the offers of cereals and fruits were included in the cult activities and the presence of charred remains would indicate the use of fire. The copious amount of chaff remains would suggest deposition of whole spikelets of grain, instead of grains already threshed

Primary extranodal diffuse large B-cell lymphomas: Many sites, many entities? Clinico-pathological, immunohistochemical and cytogenetic study of 106 cases

We analyzed the clinicopathological, immunohistochemical and cytogenetic features of 106 extranodal (EN) diffuse large B-cell lymphomas (DLBCLs) from stomach (34 cases), intestine (10), cervico-cephalic region (11), central nervous system (13), testes (21), skin (8), and miscellaneous sites (9). Hans\u2019 algorithm and the immunohistochemical double expressor score (DES) for MYC and BCL2 were applied to all cases. A subset of fifty-eight cases were analyzed with fluorescent in situ hybridization (FISH) with specific break apart probes for BCL6, MYC, BCL2, CCND1, BCL10 and MALT1 genes. Clinical records were available for all patients. The immunohistochemical study showed that, in our series of EN-DLBCLs, the Hans\u2019 subgroup and the DES differed significantly according to the site of origin. At FISH analysis, BCL6 and BCL2 were the most commonly rearranged genes in non-GC and in GC cases, respectively. Gastrointestinal lymphomas displayed the highest rate of gene rearrangements, often with MYC involvement. One testicular DLBCL showed BCL2/MYC double hit. At survival analysis, cerebral and testicular origin was associated with poor prognosis. In addition, Hans\u2019 subgroup and other immunohistochemical markers influenced patients\u2019 outcome. In conclusion, our data suggest that immunophenotypic, genetic and survival characteristics of EN-DLBCL are related to the specific primary site of the disease

Pollen and macroremains from the site “Vasca di Noceto”: an artificial basin for votive practices during the Bronze Age in Northern Italy

This research is part of the national-funded interdisciplinary SUCCESSO-TERRA Project (Human societies, climate-environment changes and resource exploitation/sustainability in the Po Plain in the mid-Holocene: the Terramare culture; PRIN-20158KBLNB) and discusses biological information of the archaeological site “Vasca di Noceto”, an artificial wooden basin dating to the Bronze Age and discovered in 2004 in the central Po Plain, near Parma. Geoarchaeological, geochronological and dendrochronological data suggest that the basin was used for ritual practices for about one hundred years (ca. 1420–1320 BC) from the inhabitants of the nearby Terramara village, which was completely removed in the nineteenth century because of quarry activities. The waterlogged anoxic clay-bearing infilling of the basin preserved the wooden architectonic structure and many biological findings submerged until their recovery. The abundance of botanical records (pollen, seeds and fruit remains) in an extraordinary state of preservation permits to investigate the use of plants in ritual contexts and to reconstruct the local plant cover influenced by the interaction with human activities near the site. Cereals and fruits were possibly used as votive offerings during ritual activities together with flowers and inflorescences, probably deposited into the water according to the observation of the preservation state of pollen from several entomophilous species
