Effect of hunting awareness on wild game meat purchase behavior

Although wild game meat constitutes a sustainable and healthy alternative to conventional meat and hunting contributes to the control of game populations, international studies on consumer attitudes towards this type of meat are still limited and no previous research has been focused on the Italian population.For the development of successful marketing strategies and/or public policy intervention, the knowledge of consumers’ purchase behavior is a key factor. Among all the determinants that can influence the behavior of consumers of hunted wild game meat (i.e. animal welfare, sustainability, ecological food choice, product safety, nutritional quality), the consumers’ awareness of hunting activity and their perceptions of wild game meat assume a crucial role.Accordingly, in this paper an online survey on a sample of 741 Italian meat consumers has been conducted to investigate the relationship between consumers’ purchase behavior and their awareness of hunted game meat and hunting practices (chi-square test, F-test). Statistically significant differences were found among segments of consumers with different levels of wild game meat consumption frequency. The analysis shows that, as expected, the highest consumption level of wild game meat relates to the highest level of general awareness of wild game meat and hunting practices.Our findings are in line with previous literature, that links positive behaviors of consumers towards wild game meat and hunting to familiarity and experience with hunting and hunters. Nonetheless, the present study provides a deeper understanding of the Italian consumers’ attitudes and perceptions of wild game meat and could suggests policy guidelines for the development of future targeted marketing strategies.

Severe ocular involvement in a newborn with Langerhans Cell Histiocytosis

Abstract Langerhans Cell Histiocytosis (LCH) is a rare proliferative disease of the mononuclear phagocyte system, characterised by tissue infiltration of CD1a + CD207+ histiocytes. The clinical presentation is variable, ranging from unifocal asymptomatic bone involvement to life-threatening multisystem disease, requiring aggressive therapeutic approaches. Intraocular involvement is uncommon and associated to poor visual and general prognosis. We report a case of LCH in a newborn with severe ocular and multisystem risk-organ involvement, unresponsive to several lines of chemotherapy. Off-label administration of vemurafenib led to dramatic improvement at systemic level; however, chronic sequelae of ocular involvement resulted in poor visual prognosis. Intraocular LCH involvement may be asymptomatic and clinical signs delayed, leading to severe complications, especially in newborns and young children. Screening for ocular involvement is essential for early treatment initiation, which can possibly improve the visual outcome. Vemurafenib is effective on systemic involvement, and its role in ocular LCH needs to be evaluated

Simboli e significati nella cultura locale di una periferia urbana: uno studio di caso

Una ricerca psicologico-clinica esplora la Cultura Locale (i significati emozionali condivisi da chi partecipa a un contesto, atti a mantenere stabilità e coesione, a regolare e l’emozionalità dei processi di convivenza) di un quartiere della periferia romana nel momento della pianificazione di servizi per la comunità. La ricerca è fondata sulla analisi del testo computer assistita (Analisi Emozionale del Testo) di interviste somministrate a 8 figure chiave, e sulla analisi delle corrispondenze multiple di 314 questionari sulla percezione soggettiva della qualità di vita e sulla anticipazione dei rapporti sociali, somministrati a cittadini del quartiere. I risultati della analisi di interviste e questionari hanno messo in luce la qualità di vita come soggettivamente percepita dagli abitanti e le caratteristiche della cultura locale del territorio oggetto dello studio. Vengono fornite indicazioni pragmatiche sulla attivazione di servizi coerenti con la cultura locale del territorio esaminato. Viene messo in evidenza il possibile contributo della psicologia clinica alle discipline geografiche, urbanistiche, ambientali.This clinical-psychological research explores the Local Culture (emotional meanings shared by people in a given context aimed at maintaining stability and unity as well as regulating emotions affecting cohabitation) of a suburban neighborhood in Rome in the phase of community service planning. The inquiry is based on a computer-assisted text analysis (Emotional Text Analysis) of interviews of 8 key figures, and on the multiple correspondence analysis of questionnaires on the subjective perception of the quality of life and on the expectation of social relationships. The questionnaires have been administered to 314 inhabitants. The results of the analysis of interviews and questionnaires highlighted the quality of life in terms of subjective perception and the specific features of the local culture of the territory considered for this study.

Almost 79% survival rate at 10‐year follow‐up for the patellofemoral joint arthroplasty: An Italian prosthetic registry study

PurposeThe aims of the present study were (1) to evaluate the survival of patellofemoral joint (PFJ) arthroplasty in a large cohort of patients using data obtained from an Italian regional arthroplasty registry and (2) to collect clinical outcomes of a subgroup of patients, with a minimum follow-up of 4 years. The hypotheses were that PFJ arthroplasty is a procedure that had good survival and clinical outcomes, not inferior to those reported in the literature for primary total knee arthroplasty (TKA).MethodsThe Register of Orthopaedic Prosthetic Implants (RIPO) of Emilia-Romagna (ER) (Italy) database was searched for the inclusion of all PFJ arthroplasties implanted between 2003 and 2019. PFJ arthroplasties were excluded if they were implanted in patients who lived outside of the ER. The survival information was extrapolated from the RIPO considering the partial or total revision of the implant as failure; moreover, a subgroup of patients was contacted and interviewed by telephone to collect clinical outcomes. Descriptive statistics were used to summarise the data. The survival curve was calculated and plotted using the Kaplan-Meier method.ResultsA total of 126 arthroplasties in 114 patients were included in the final analysis (mean age at surgery 60.1 +/- 11.5 years old). The main causes of patellofemoral arthroplasty were primary osteoarthritis (88%) and posttraumatic arthritis (7%). The survival was 90.4 +/- 30.6 and 78.8 +/- 51.5 at 5 and 10 years of follow-up, respectively. At the latest follow-up, 23 implants failed (18.3%). The main cause of revision was osteoarthrosis progression (34.8%). A total of 44 patients were contacted by telephone to collect clinical outcomes: Western Ontario and McMaster Universities Osteoarthritis Index, functional Knee Society Score, Forgotten Joint Score and Oxford Knee Score. These patients reported good to excellent scores at a medium follow-up of 10.3 +/- 4.7 years.ConclusionsThe PFJ showed good survival and clinical outcomes and could be considered a valuable option for patients affected by isolated patellofemoral osteoarthritis.Level of EvidenceLevel IV

Assessing Risks Awareness in Operating Rooms among Post-Graduate Students: A Pilot Study

Background: In this study, we promote a global approach to occupational risk perception in order to improve occupational health and safety training programs. The study investigates the occupational risk perception of operating room healthcare workers using an Analytic Hierarchy Process approach. Methods: A pilot study was carried out through a cross-sectional survey in a university hospital in Southern Italy. An ad hoc questionnaire was administered to enrolled medical post-graduate students working in the operating room. Results: Fifty medical specialists from seven fields (anaesthetists, digestive system surgeons, general surgeons, maxillofacial surgeons, thoracic surgeons, urologists, and gynaecologists) were questioned about perceived occupational risk by themselves. Biological, ionizing radiation, and chemical risks were the most commonly perceived in order of priority (w = 0.300, 0.219, 0.210). Concerning the biological risk, gynaecologists unexpected perceived this risk as less critical (w = 0.2820) than anaesthesiologists (w = 0.3354), which have the lowest perception of the risk of ionizing radiation (w = 0.1657). Conclusions: Prioritization methods could improve risk perception in healthcare settings and help detect training needs and perform sustainable training programs

Localized formation and size tuning of CdS nanocrystals upon irradiation of metal precursors embedded in polymer matrices

We present a method of spatial and dimensional controlled formation of CdS quantum dots into polymer matrices by light irradiation. The initial samples consist of Cd thiolate precursors doped in TOPAS polymer matrix. Under pulsed UV laser irradiation the precursors are photolysed driving to the nucleation of CdS nanocrystals, with increasing size and concentration, related to the number of UV pulses. The formed quantum dots are localized in the irradiated area, while the host polymer remains macroscopically unaffected by the UV irradiation. In this study we investigate how the formation of the nanocrystals (size, dimensions, and concentration) is affected by the use of different irradiation conditions (wavelength, number of pulses), revealing information about the different pathways followed during the formation. The change of the size of the dots results in the change of the peak of their emission due to the quantum size effect, which is studied by fluorescence measurements. The results are reinforced by TEM microscopy and by XRD measurements. The main advantages of the presented method are the size tuning of the produced dots and their spatial confinement inside the host matrix, not possible by the other methods used until now (thermal annealing, mixing etc.)

Comparison between laser-induced nucleation of ZnS and CdS nanocrystals directly into polymer matrices

The nucleation of two kinds of crystalline nanoparticles, zinc sulfide (ZnS), and cadmium sulfide (CdS), is achieved directly into specific sites of polymer matrices after their irradiation with UV laser pulses. The starting samples consist of polymers doped with precursors of Zn or Cd thiolate that are proved to decompose after the absorption of UV light, resulting into the nanoparticles formation. The growth of the crystalline nanostructures is followed throughout the irradiation of the samples with successive incident pulses, by different methods, such as transmission electron microscopy, atomic force microscopy, confocal microscopy, and X-ray diffraction. Special attention is paid to the difference of the formation pathways of the two kinds of nanoparticles studied, because the Cd thiolate precursor exhibits much higher absorption efficiency than the Zn thiolate one, at the applied UV wavelength. Indeed, CdS nanoparticles become evident after the very first incident UV pulses, whereas the formation of ZnS nanocrystals requires rather prolonged irradiation, always through a macroscopically nondestructive procedure for the polymer matrix.

Management of elderly and unfit patients with chronic lymphocytic leukemia

Introduction: About 75% of patients with chronic lymphocytic leukemia (CLL) are more than 65 years at the time of diagnosis. Treatment of the elderly remains complicated due to multiple factors, such as comorbidities, decline in functional reserve and fitness. Since chronological age by itself cannot properly predict life expectancy and treatment tolerance, an accurate assessment of the fitness status is of crucial importance for an optimal treatment choice. Areas covered: This review will discuss the most relevant aspects concerning the issues experienced in the management of elderly/unfit patients with CLL. The most frequently observed age-related toxicities, fitness assessments, supportive care measures and treatment options for elderly patients and for patients who are deemed unfit will be discussed. Literature search methodology included examination of PubMed index. Expert commentary: During the last decade, different trials focusing on elderly/unfit patients have investigated more tolerable chemoimmunotherapy schedules and, more recently, the activity and safety of chemo-free regimens. Chlorambucil combined with an anti-CD20 monoclonal antibody has shown clinical activity with a relatively good profile of toxicity. The recent introduction of the B-cell receptor antagonists, ibrutinib and idelalisib, and other targeted drugs in development (e.g. venetoclax), is broadening the therapeutic armamentarium of elderly CLL patients

Synthesis, morphology and crystallization kinetics of Polyheptalactone (PHL)

Aliphatic polyesters are widely studied due to their excellent properties and low-cost production and also because, in many cases, they are biodegradable and/or recyclable. Therefore, expanding the range of available aliphatic polyesters is highly desirable. This paper reports the synthesis, morphology, and crystallization kinetics of a scarcely studied polyester, polyheptalactone (PHL). First, we synthesized the η-heptalactone monomer by the Baeyer–Villiger oxidation of cycloheptanone before several polyheptalactones of different molecular weights (in the range between 2 and 12 kDa), and low dispersities were prepared by ring-opening polymerization (ROP). The influence of molecular weight on primary nucleation rate, spherulitic growth rate, and overall crystallization rate was studied for the first time. All of these rates increased with PHL molecular weight, and they approached a plateau for the highest molecular weight samples employed here. Single crystals of PHLs were prepared for the first time, and hexagonal-shaped flat single crystals were obtained. The study of the crystallization and morphology of PHL revealed strong similarities with PCL, making PHLs very promising materials, considering their potential biodegradable character.This work has received funding from the Basque Government through grant IT1503-22.
