The Cost of Loneliness: Assessing the Social Relationships of the Elderly via an Abbreviated Sociotype Questionnaire for inside and outside the Clinic.

Gauging the social relationships of the elderly is a significant sociometric research subject and a deep biomedical concern-particularly after the COVID-19 pandemic. It is imperative for facultatives in primary care, for geriatric clinics, and for social care services. In this respect, this article explores the validity of an abbreviated version of the Sociotype Questionnaire (SOCQ), a tool previously developed by the authors for assessing the social relationships of the general population, now specifically addressed to the elderly population. The aim is to construct a 4-item dichotomous scale (SOCG-4) out of the 12 items of the original scale of the SOCQ, so that it can serve to discriminate among the patients in primary care and the geriatric clinic, helping the facultative to find those in need of social care or of psychosocial intervention. The population data have been obtained from a series of previous studies on social relationships in different segments of the elderly population (Ntotal = 915). The resulting abbreviated version of SOCG-4 was extracted by means of confirmatory factor analysis, with the congruence, validity, and relationship with the determinants as close to optimal. The significant correlations with SOCQ (0.82), UCLA (-0.55), Barthel (0.40), and other relevant tests are obtained. The test was also put to trial in a pilot study, being applied to 150 subjects via phone surveys, home visiting, and geriatric clinic-it becomes particularly useful for assessing the social relationships in geriatric clinic use. The 4-item Geriatric Sociotype scale (SOCG-4) appears as a valid measurement instrument for use in the clinic and in other social care instances.

Cytogenetic, fluorescence in situ hybridization, and immunohistochemistry studies in a malignant pleural solitary fibrous tumor.

Pleural solitary fibrous tumor is a normally benign fibroblastic neoplasm; its recurrences and metastasis are associated with clinical and morphological characteristics of variable interpretation and efficacy of surgical treatment. Immunohistochemistry techniques have contributed decisively to the correct diagnosis of the lesion and define its prognosis. In the present case, cytogenetic and fluorescence in situ hybridization analyses revealed multiple chromosomal aberrations, including a del(9)(q21qter) and a marker chromosome ish der(9)(ABL+). The present data support but do not resolve the possible involvement of a gene on 9q22 in the biological behavior of these tumors, and the ABL rearrangements and deletions of 1p and 10p suggest another possible malignant component.
