Activity Budgets and Forage Selection of Podolian Cattle, a Semiwild Bovine Breed

This study aimed to describe the behaviour of Podolian breed, a semiwild cattle breed kept in a natural environment (as either a small group of young bulls or cows within a family herd), and the interaction of these animals with the environment in terms of ingestion from natural pastures. Diurnal grazing behavioural pattern was monitored through continuous focal animal recording method. The activity budget of free-ranging animals was characterized by high locomotor and feeding activities. They exhibited a high degree of adaptability to the local phytocoenosis with high levels of ferns' and tree foliage intakes performed by cows and the selection of a diet more nutritious than pasture performed by young bulls. These results along with the low levels of agonistic interactions recorded in the two experiments suggest that extensive systems based on grazing allow social stability and provide a natural environment for the expression of cattle species-specific behaviour

Perception of Ecosystem Services from Podolian Farming System in Marginal Areas of Southern Italy

Ecosystem services (ESs) are gaining increasing interest among researchers, local communities, and policymakers. The farming of Podolian cattle in the remote and marginal areas of southern Italy plays an important socio-economic role. This study aimed to assess the perception of ESs provided by Podolian cattle farming in the Basilicata region among the local actors and stakeholders. Using a questionnaire administered to 198 respondents, the level of agreement and disagreement was assessed on a 1–5 scale for the four main ESs: cultural, regulating, supporting, and provisioning. On average, the perception of ESs related to Podolian cattle farming was positive. However, the role of promoting tourism in the region was somewhat controversial, and the results in terms of regulation were divisive. The perception of provisioning services had a highly positive result. Further research is needed to better understand the role of Podolian cattle farming in the Basilicata region, providing more explicit guidance for local communities and policymakers

Life Cycle Assessment of Dairy Buffalo Calves in an Italian Farm

The aim of this paper was to examine the environmental consequences of raising buffalo calves, as assessed by life cycle assessment. Life cycle assessment has been widely used to assess the environmental impact of different livestock production systems. The primary data were collected from 32 animals aged 0-90 days. Calves were allowed to uptake colostrum before separation from their mothers within 24-h after birth. After separation, the animals were kept individually (1 x 2 m) for 8 weeks and then housed in groups of 8 in straw-bedded pens (5 x 8 m). According to the results of the analysis, the contributions from all calves to global warming potential, acidification potential, eutrophication potential, non-renewable energy use was high. In particular, the impact generated from global warm potential was 7 kg CO2 - eq per day, and the impact of non-renewable energy use was 38 MJ - eq per day. Our results estimated for the first time the environmental impact generated from buffalo calves. We conclude that the strategies to mitigate the effects on the environment impact must start from the birth of the buffalo calves and then continue throughout its life cycle

Sensory Profile and Consumer Liking of Sustainable Salamis Differing in Wild Boar Meat and Seasoning Ingredients Addition

: The production of game meat is a proven way of promoting sustainable food, which is also consistent with the proper management of the expansion of the wild boar population in Italy. In the present study, we investigated consumer response to sensory attributes and consumer preference for ten types of "cacciatore" salamis prepared with different mixtures of wild boar/pork (30/50 or 50/50) and spice ingredients. PCA analysis showed a clear characterization of the salamis based on the first component with the hot pepper powder and fennel types differing from the others. For the second component, salamis without flavorings could be discriminated by those flavored with aromatized garlic wine or with black pepper only. The main findings of the hedonic test revealed that products with hot pepper and fennel seeds received the highest ratings, as well as satisfactory acceptance in the consumer test sensory analysis for eight out of ten products. The panelists and consumers' ratings were influenced by the flavors used, but not by the ratio of wild boar to pork. This gives us the opportunity to produce more cost-effective and environmentally friendly products, as doughs with a high proportion of wild boar meat can be used without affecting product preference

Psychological Distress in Breast Cancer Patients during the Italian COVID-19 Pandemic

Background. The emergency caused by the SARS-CoV-2 pandemic exacerbated psychological distress. Our aim was to investigate the impact of breast cancer on patients' lives during the Italian lockdown. Methods. Sixty-five female breast cancer patients were studied, assessing the level of psychological distress with the Hospital Anxiety and Depression Scale (HADS) and the impact of the cancer diagnosis (Impact of Event Scale-Revised-IES-R). In addition, we compared these data with a matched group of breast cancer patients enrolled in 2019. Results. Patients enrolled in 2020 had statistically higher levels of anxious symptomatology and higher levels of traumatic symptomatology due to the cancer diagnosis. A mediation analysis was performed to determine how the experience of distress due to COVID-19 negatively impacted the level of anxiety and amplified the impact of the diagnosis with a significant increase in traumatic symptoms. Conclusions. Considering the vulnerability of these patients and the serious and novel situation that the healthcare system is currently facing, we would like to point out the importance of structured and organised psychological support for these patients

Food neophobia, odor and taste sensitivity, and overall flavor perception in food

Smell, which allows us to gather information about the hedonic value of an odor, is affected by many factors. This study aimed to assess the relationship among individual factors, odor sensitivity, and enjoyment, and to evaluate how overall flavor perception and liking in actual food samples are affected by odor sensitivity. A total of 749 subjects, from four different Italian regions, participated in the study. The olfactory capabilities test on four odors (anise, banana, mint, and pine), as well as PROP (6-n-prpyl-2-thiouracil) status and food neophobia were assessed. The subjects were clustered into three groups of odor sensitivity, based on the perceived intensity of anise. The liking and intensity of the overall flavor were evaluated for four chocolate puddings with increasing sweetness (C1, C2, C3, and C4). The individual variables significantly affected the perceived intensity and liking of the odors. Even if all of the odor sensitivity groups perceived the more intensely flavored samples as the C1 and C4 chocolate puddings, the high-sensitivity group scored the global flavor of all of the samples as more intense than the low-sensitivity group. The low-sensitive subjects evaluated the liking of the sweeter samples with higher scores than the moderate-sensitive subjects, whereas the high-sensitive subjects gave intermediate scores. In conclusion, odor sensitivity plays a pivotal role in the perception and liking of real food products; this has to be taken into account in the formulation of new products, suitable for particular categories with reduced olfactory abilities

Phenotyping of chondrocytes from human osteoarthritic cartilage: chondrocyte expression of beta integrins and correlation with anatomic injury

Chondrocyte-ECM (extracellular matrix) interactions are believed to play a pivotal role in the development and metabolic homeostasis of articular cartilage. Cell surface adhesion molecules have been reported to modulate chondrocyte binding to ECM (collagen, fibronectin, laminin) and they also act as transducers of critical signals in many biological processes such as growth, differentiation, migration and matrix synthesis. Recently, it has been shown that normal human articular chondrocytes strongly express beta1 integrins, which are constituted by a common chain (beta1) and a variable alphachain, but the behaviour of these molecules in human osteoarthritic cartilage has not been extensively investigated. We studied the expression of beta integrins (beta1-5, alpha1-6, av chains), LFA-1, ICAM-1 and CD44, on freshly isolated chondrocytes obtained from 10 osteoarthritic patients undergoing surgical knee replacement. Chondrocytes were isolated by enzymatic digestion from three zones of each articular cartilage with a differing degree of macroscopic and microscopic damage. Integrin expression and cell cycle analysis were carried out by flowcytometry. Chondrocytes from costal cartilages of 5 human foetuses were also studied. Chondrocytes from osteoarthritic cartilage expressed high levels of beta1 integrin and, at different percentages, all the alphachains. The alphachain most frequently expressed was alpha1, foilowed by alpha3, alpha5, alpha2, alphav. Integrin expression decreased from the least to the most damaged zone of articular cartilage and cell cycle analysis showed that proliferating chondrocytes (S phase) were prevalent on the latter zone. beta2, beta3, beta2, beta5, CD44, LFA-1/ICAM-1 complex were very low expressed. Fetal chondrocytes strongly expressed beta1 and beta5 chains. These data provide evidence to show that integrin expression on human chondrocytes changes in osteoarthritis and suggest that perturbations of chondrocyte-ECM signalling occur in the development of the disease. The different pattern of expression of beta1 and beta5 chains on adult and fetal chondrocytes leads to speculate that integrins play a key role in control of cartilage morphogenesis and differentiation

Intraoperative breast specimen assessment in breast conserving surgery: comparison between standard mammography imaging and a remote radiological system.

The aim of this paper was to compare standard specimen mammography (SSM) with remote intraoperative specimen mammography (ISM) assessment in breast conserving-surgery (BCS) based on operative times, intraoperative additional excision (IAE) and re-intervention rates. We retrospectively compared 129 consecutive patients (136 lesions) who had BCS with SSM at our centre between 11/2011 and 02/2013 with 138 consecutive patients (144 lesions) who underwent BCS with ISM between 08/2014 and 02/2015. SSM or ISM were performed to confirm the target lesions within the excised specimen and margin adequacy. The utility of SMM and ISM was evaluated considering pathology as gold-standard, using χ2 or Fisher’s exact tests for comparison of categorical variables, and non-parametric Mann–Whitney test for continuous variables

Twelve Variants Polygenic Score for Low-Density Lipoprotein Cholesterol Distribution in a Large Cohort of Patients With Clinically Diagnosed Familial Hypercholesterolemia With or Without Causative Mutations

: Background A significant proportion of individuals clinically diagnosed with familial hypercholesterolemia (FH), but without any disease-causing mutation, are likely to have polygenic hypercholesterolemia. We evaluated the distribution of a polygenic risk score, consisting of 12 low-density lipoprotein cholesterol (LDL-C)-raising variants (polygenic LDL-C risk score), in subjects with a clinical diagnosis of FH. Methods and Results Within the Lipid Transport Disorders Italian Genetic Network (LIPIGEN) study, 875 patients who were FH-mutation positive (women, 54.75%; mean age, 42.47±15.00 years) and 644 patients who were FH-mutation negative (women, 54.21%; mean age, 49.73±13.54 years) were evaluated. Patients who were FH-mutation negative had lower mean levels of pretreatment LDL-C than patients who were FH-mutation positive (217.14±55.49 versus 270.52±68.59 mg/dL, P<0.0001). The mean value (±SD) of the polygenic LDL-C risk score was 1.00 (±0.18) in patients who were FH-mutation negative and 0.94 (±0.20) in patients who were FH-mutation positive (P<0.0001). In the receiver operating characteristic analysis, the area under the curve for recognizing subjects characterized by polygenic hypercholesterolemia was 0.59 (95% CI, 0.56-0.62), with sensitivity and specificity being 78% and 36%, respectively, at 0.905 as a cutoff value. Higher mean polygenic LDL-C risk score levels were observed among patients who were FH-mutation negative having pretreatment LDL-C levels in the range of 150 to 350 mg/dL (150-249 mg/dL: 1.01 versus 0.91, P<0.0001; 250-349 mg/dL: 1.02 versus 0.95, P=0.0001). A positive correlation between polygenic LDL-C risk score and pretreatment LDL-C levels was observed among patients with FH independently of the presence of causative mutations. Conclusions This analysis confirms the role of polymorphisms in modulating LDL-C levels, even in patients with genetically confirmed FH. More data are needed to support the use of the polygenic score in routine clinical practice
