Social Love and the Critical Potential of People: When the Social Reality Challenges the Sociological Imagination

This book unveils the concept of social love as a kind of "Karst River" that flows through the history of sociology, reassessing it as a form criticism by people in everyday life. Adopting an interdisciplinary perspective, this book offers both theoretical and empirical reflections on social love. It shows that love is not only central to the human experience, but that it can also help to interpret and intervene in social problems such as climate change, poverty, xenophobia, and the (post-)Covid crisis, recognizing people as actors in social change. It explores the idea of love as a key element in the promotion of solidarity and recognition in today's plural and unequal societies. Based on empirical research on social love conducted through both qualitative and quantitative methods, especially in Europe and Latin America, this book explores the social dimension of love. Providing overviews on key questions and studies on current issues, the book is essential reference and resource for researchers, students, social workers, and professionals in social sciences, social philosophy, anthropology, social psychology, sociology of emotions and postmodern literature. © 2023 selection and editorial matter, Silvia Cataldi and Gennaro Iorio.

Nitrogen dioxide pollution increases vulnerability to COVID-19 through altered immune function.

Previous ecological studies suggest the existence of possible interplays between the exposure to air pollutants and SARS-CoV-2 infection. Confirmations at individual level, however, are lacking. To explore the relationships between previous exposure to particulate matter < 10 µm (PM10) and nitrogen dioxide (NO2), the clinical outcome following hospital admittance, and lymphocyte subsets in COVID-19 patients with pneumonia. In 147 geocoded patients, we assessed the individual exposure to PM10 and NO2 in the 2 weeks before hospital admittance. We divided subjects according to the clinical outcome (i.e., discharge at home vs in-hospital death), and explored the lymphocyte-related immune function as an index possibly affecting individual vulnerability to the infection. As compared with discharged subjects, patients who underwent in-hospital death presented neutrophilia, lymphopenia, lower number of T CD45, CD3, CD4, CD16/56 + CD3 + , and B CD19 + cells, and higher previous exposure to NO2, but not PM10. Age and previous NO2 exposure were independent predictors for mortality. NO2 concentrations were also negatively related with the number of CD45, CD3, and CD4 cells. Previous NO2 exposure is a co-factor independently affecting the mortality risk in infected individuals, through negative immune effects. Lymphopenia and altered lymphocyte subsets might precede viral infection due to nonmodifiable (i.e., age) and external (i.e., air pollution) factors. Thus, decreasing the burden of air pollutants should be a valuable primary prevention measure to reduce individual susceptibility to SARS-CoV-2 infection and mortality.

Linking psycho-physical profiles to different training condition during COVID-19 confinement

At the end of the period of home confinement due to Covid-19 lockdown, the 12-item Health Survey (SF-12) questionnaire was used to assess the quality of life. Participants also completed the Profile of Mood State (POMS) for the assessment of mood. Data were collected through an online form on a sample of 143 adults (71% aged 18-30, 12% 31-40, 11% 41-50 and 6% aged >50, 58% males and 42% females). Subjects were divided into 5 groups according to the corresponding training condition followed during the first lockdown. Training classes were carried out via online guided distance learning. 19 subjects (Group FT) received functional training classes as they did before the confinement. Group FTL (29 subjects) followed another functional training only during the lockdown. Group DT (46 subjects) continued a non-functional type training also during lockdown;group TL performed one training only during lockdown. Finally, group NT (25 subjects) received no training. Results from SF-12 showed no significant differences between groups. POMS result indicated that only the FT group had positive effects on anxiety and depression, whereas a functional training performed with a different program (FTL) resulted in no significant effects on anxiety compared to NA group.

Ongoing COVID-19 vaccination in Italy. Online survey of gender- and age-related side effects

Background: Evidences suggest that gender may influence the response to various vaccines in terms of immune response and side effects. Whether similar differences also occur with COVID-19 vaccine, is still uncertain. Materials and Methods: In March 2021, we advertised a short anonymous questionnaire (Google forms) to medical doctors, nurses, postgraduates, students and general public, consisting of 30 questions exploring 16 possible side effects (local pain or hardness, swelling, redness, allergic reaction, tiredness, headache, sleep disorders, myalgia, fever, enlarged lymph nodes, irritability, diarrhea, urticaria, vomiting, anaphylaxis). We recorded side effects after 1st dose, and within one week after 2nd dose. Data were analyzed according to gender and seven age groups. Results: We received 1,034 questionnaires from all over Italy (369 males, 665 females, age range 20-83 years). Injected vaccines were Pfizer-BioNTech (96.9%), Astra-Zeneca (2.4%), Moderna (0.7%). Major adverse events were absent. Minor adverse events occurred with both 1st dose (76.0%) and 2nd dose (78.0%) and were invariably higher in females than in males (1st dose: 79.4% vs 69.9% p = 0.0006;2nd dose: 81.8% vs 70.7%, p = 0.00004). The significant cluster of adverse events were local pain, redness, hardness at the injection site, fever, sleep disturbances, headache, lymph nodes enlargement following both doses (0.00001 < p < 0.02). Effects disappeared within 48hrs in 80% of cases (range 1-7 days). The gender difference was confirmed in the age class 30-39 after 1st dose (85.8% vs 70%, in females and males, respectively p = 0.03), and in the age classes 30-39 (84.6% vs 75.5%, in females and males, respectively p = 0.03) and 40-49 (74.8% vs 57.9%, in females and males, respectively p = 0.02) after 2nd dose. Fever tended to be more frequent in females after the 1st dose (6.5% vs 3.8%) and became significantly higher after the 2nd dose (32.9% vs 17.3%, p = 0.00001). After 50 years of age, the rate of all the recorded adverse events was similar between genders. Conclusions: COVID-19 vaccines generate frequent, although mild side effects with a gender (female) prevalence, especially in the age range 30-49 years. The gender difference disappears after 50 years of age, thus pointing to possible involvement of sex hormones and attenuated immune response.
