Detenzione parentale e comportamenti delinquenziali nella prole: quale possibile intervento*?

Research on the health of children after one of their parent’s imprisonment is relatively poor despite studies that link adverse experiences of childhood to a series of physical and mental health conditions. In this review, several clinical trials have been examined to examine the risks of child exposure to an unstable and dysfunctional family structure due to detention of one or both parents. Among the aspects related to detention, the one most concerning for prisoners is the separation from the family, and in particular from the children. From the offspring point of view, the detention of one parent translates to a loss of a stable reference point, which over the years leads to them taking less advisable choices that in turn make detention more likely. Studies have shown that, over the years, minor children of detainees develop acceptance towards parental detention, with normalization of event up to ignoring the socially shared concept of “detention” which morphs into the idea of what delinquency represents in micro and macro criminality contexts. It becomes important to foster relationships with children and with the prisoner’s family, but it becomes even more important that the prisoner embarks on a path that leads them to regain the parenting role, which allows them to feel like a person with resources to protect and with relationships to cultivate

Biophysical characterization of Met-G-CSF: effects of different site-specific mono-pegylations on protein stability and aggregation.

The limited stability of proteins in vitro and in vivo reduces their conversion into effective biopharmaceuticals. To overcome this problem several strategies can be exploited, as the conjugation of the protein of interest with polyethylene glycol, in most cases, improves its stability and pharmacokinetics. In this work, we report a biophysical characterization of the non-pegylated and of two different site-specific mono-pegylated forms of recombinant human methionyl-granulocyte colony stimulating factor (Met-G-CSF), a protein used in chemotherapy and bone marrow transplantation. In particular, we found that the two mono-pegylations of Met-G-CSF at the N-terminal methionine and at glutamine 135 increase the protein thermal stability, reduce the aggregation propensity, preventing also protein precipitation, as revealed by circular dichroism (CD), Fourier transform infrared (FTIR), intrinsic fluorescence spectroscopies and dynamic light scattering (DLS). Interestingly, the two pegylation strategies were found to drastically reduce the polydispersity of Met-G-CSF, when incubated under conditions favouring protein aggregation, as indicated by DLS measurements. Our in vitro results are in agreement with preclinical studies, underlining that preliminary biophysical analyses, performed in the early stages of the development of new biopharmaceutical variants, might offer a useful tool for the identification of protein variants with improved therapeutic values

Anxiety, Motives, and Intention for Physical Activity during the Italian COVID-19 Lockdown: An Observational Longitudinal Study

Background: The coronavirus (COVID-19) pandemic led governments to adopt strict containment measures to avoid spreading the virus. These essential measures led to home confinement that influenced both the physical and mental health of populations. Physical activity plays a key role in preventing chronic diseases and promoting protective psychological factors. In the context of a lockdown, understanding the motives that guide people to enact physical activity is an important issue for public health. The present study aimed to evaluate the relation between autonomous motivation and physical activity, considering the role of behavioral intention and anxiety in a longitudinal moderated mediation model. Methods: Italian participants (N = 86; meanage = 29.74, standard deviation = 9.74; female = 53.5%) completed a booklet composed of different questionnaires (motivation, intention, anxiety, and physical activity) 3 weeks apart. Results: The hypothesized model is supported by the evidence; both autonomous motivation and intention are direct predictors of physical activity. The results also show that the direct effect of autonomous motivation on physical activity is stronger in participants with low anxiety, while high levels of anxiety are a significant moderator of the intention–behavior relation. Conclusions: In conclusion, a multidisciplinary approach should be promoting methods and infrastructures to permit people to adhere to physical activity, as a front line against any health emergency

<p>A) Light scattering intensity, in arbitrary units, as a function of the incubation time at 55°C. At the zero time the bath temperature was changed from 37°C to 55°C. B) Polydispersity index (Eq.3) of the non-pegylated Met-G-CSF and of the two isomeric pegylated proteins as a function of the incubation time. C) Distribution of the hydrodynamic radii corresponding to the most abundant component in the DLS decay.

D) Met-G-CSF, Met-G-CSF-Met1-PEG and Met-G-CSF-Gln135-PEG second derivative FTIR spectra measured after 7 hours of incubation at 55°C.Concerning the size of the protein aggregates, the diffusion coefficients (Eq.1) were used to evaluate the protein aggregate hydrodynamic radii through Eq.2. Non-pegylated Met-G-CSF displayed an average hydrodynamic radius of 1.4±0.4 nm at 37°C with negligible presence of protein aggregates. At 55°C, after thermal equilibrium was reached, we found instead a prevalent component with R_h = 70±20 nm. It should be noted that the value of 70 nm represents the average size of protein aggregates still in solution after 7 hours of incubation at 55^oC.</p

Global attitudes in the management of acute appendicitis during COVID-19 pandemic: ACIE Appy Study

Background: Surgical strategies are being adapted to face the COVID-19 pandemic. Recommendations on the management of acute appendicitis have been based on expert opinion, but very little evidence is available. This study addressed that dearth with a snapshot of worldwide approaches to appendicitis. Methods: The Association of Italian Surgeons in Europe designed an online survey to assess the current attitude of surgeons globally regarding the management of patients with acute appendicitis during the pandemic. Questions were divided into baseline information, hospital organization and screening, personal protective equipment, management and surgical approach, and patient presentation before versus during the pandemic. Results: Of 744 answers, 709 (from 66 countries) were complete and were included in the analysis. Most hospitals were treating both patients with and those without COVID. There was variation in screening indications and modality used, with chest X-ray plus molecular testing (PCR) being the commonest (19\ub78 per cent). Conservative management of complicated and uncomplicated appendicitis was used by 6\ub76 and 2\ub74 per cent respectively before, but 23\ub77 and 5\ub73 per cent, during the pandemic (both P < 0\ub7001). One-third changed their approach from laparoscopic to open surgery owing to the popular (but evidence-lacking) advice from expert groups during the initial phase of the pandemic. No agreement on how to filter surgical smoke plume during laparoscopy was identified. There was an overall reduction in the number of patients admitted with appendicitis and one-third felt that patients who did present had more severe appendicitis than they usually observe. Conclusion: Conservative management of mild appendicitis has been possible during the pandemic. The fact that some surgeons switched to open appendicectomy may reflect the poor guidelines that emanated in the early phase of SARS-CoV-2
