The isolation paradox:A comparative study of social support and health across migrant generations in the US

Social isolation and international migration have potentially adverse effects on physical and mental health, and may compound each other when migrants have limited access to supportive social networks. This problem may be particularly serious in older age groups, who are more vulnerable to illness and isolation. We analyze population representative data from a detailed survey of social networks and health in the San Francisco Bay Area, U.S., to compare access to different types of social support and health outcomes among first-generation migrants, second-generation migrants, and nonmigrants between 50 and 70 years old (N = 674). We find that first-generation migrants report systematically lower levels of social support and poorer self-rated health compared to nonmigrants, even after controlling for sociodemographic characteristics. While social support is strongly and positively associated with health in the general population, this relationship is null or, in some cases, reversed among migrants in the first and second generations. These results provide further evidence that migration operates as an adverse social determinant of health, and suggest an isolation paradox: migrants are healthier than nonmigrants only at very low levels of social support, and they do not experience the same beneficial health effects of social support as nonmigrants

Developing Capacity, Skills, and Tobacco Control Networks to address Tobacco-related Disparities: Leadership and Advocacy Institute to Advance Minnesota’s Parity for Priority Populations (LAAMPP)

Priority populations disproportionately experience tobacco-related disparities, despite population level declines in tobacco use. The Leadership and Advocacy Institute to Advance Minnesota’s Parity for Priority Populations (LAAMPP) recruits and trains African immigrants/African Americans, Asian Americans/Pacific Islanders, American Indians, Chicano/Latinos, and LGBTQ community members to develop leaders to address tobacco harms in their communities. This paper describes and evaluates the LAAMPP Institute, and discusses lessons learned through the Institute and future directions for community-based tobacco-control efforts. The mixed-methods evaluation included qualitative key informant interviews with LAAMPP Fellows and community and project contacts, a Skills Assessment Tool, project case studies, and a social network analysis of the Fellows’ tobacco-control social networks at baseline and follow-up. At follow-up, Fellows’ tobacco control networks were larger, more extensive and diverse, and included more actors perceived to be influential in tobacco control. Fellows’ skills increased in core competencies (tobacco control, advocacy, facilitation, collaboration, cultural/community competence) and Fellows used tobacco, advocacy and cultural/community competencies more frequently. Four of five cohorts successfully passed policies. The results of LAAMPP suggest that a cross-cultural leadership institute contributes to the successful development of capacity and leadership skills among priority populations and may be a useful model for others working toward health equity

Transnationalism and Belonging: The Case of Moroccan Entrepreneurs in Amsterdam and Milan

Research on migrant transnationalism has mostly focused on particular transnational activities, their salience in various contexts and populations, and their relationship with migrant incorporation. Less attention has been paid to the interplay between the different domains of transnationalism (economic, political, and socio-relational) and to the way in which they affect migrants’ identity. This study investigates whether and how one domain of migrant transnationalism—transnational entrepreneurship—influences migrants’ (1) transnational involvement in other domains and (2) sense of belonging to different social groups and places. Focusing on the case of Moroccan entrepreneurs in Amsterdam, the Netherlands, and Milan, Italy, we compare transnational migrant entrepreneurs, whose business is based on cross-border relationships and exchanges, with domestic migrant entrepreneurs, who are active exclusively in the destination country. Combining quantitative and qualitative data, we find that transnational entrepreneurs differ from domestic entrepreneurs mostly in terms of socio-relational transnational involvement. On the other hand, transnational entrepreneurship does not substantially change transnational practices in other domains or sense of belonging among Moroccan migrants

Takayasu arteritis: a cohort of Italian patients and recent pathogenetic and therapeutic advances

Takayasu arteritis (TAK) is a rare granulomatous vasculitis of unknown etiology that mainly affects the aorta and its major branches. The aim is to describe the clinical features, diagnostic procedures, pathogenesis, and management of TAK in a longitudinal cohort of patients recruited within a single region of southern Italy. The cohort included 43 patients who were diagnosed with TAK and followed up according to a standard protocol, in a collaboration between four university tertiary referral centers and a regional hospital. Clinical and imaging classification criteria were those established by the American College of Rheumatology. Thirty-five patients (81.4%) were female, and the mean age at disease onset was 32.6 (range 16-54) years. Angiographic assessment of the vascular involvement allowed disease classification in five different types. Clinical features ranged from constitutional symptoms in the early inflammatory stage of the disease to cardiovascular ischemic symptoms in the late, chronic stage. Noninvasive imaging techniques were employed to assess the extent and severity of the arterial wall damage and to monitor the clinical course and response to therapy. Medical treatment, based on pathogenetic insights into the roles of humoral and cell-mediated immune mechanisms, included glucocorticoids mostly combined with steroid-sparing immunosuppressive agents and, in patients with relapsing/refractory disease, biologic drugs. Significant clinical and angiographic differences have been detected in TAK patients from different geographic areas. Patients with life-threatening cardiovascular and neurologic manifestations as well as sight-threatening ophthalmologic signs and symptoms should be promptly diagnosed, properly treated, and closely followed up to avoid potentially severe consequences

Chronic cerebrospinal venous insufficiency in multiple sclerosis: a highly prevalent age-dependent phenomenon

BACKGROUND: This study aimed to investigate the prevalence and clinical relevance of chronic cerebrospinal venous insufficiency (CCSVI) in multiple sclerosis (MS) patients and healthy controls using extra- and intracranial colour Doppler sonography. METHODS: We examined 146 MS patients, presenting with a clinically isolated syndrome, relapsing-remitting, secondary progressive, or primary progressive MS, and 38 healthy controls. Sonographic examination was performed according to Zamboni’s protocol and was performed by three independent sonographers. The results of sonographic examination were compared with clinical and demographic characteristics of the patients. RESULTS: CCSVI, defined as the presence of at least two positive Zamboni’s criteria, was found in 76% of MS patients and 16% of control subjects. B-mode anomalies of internal jugular veins, such as stenosis, malformed valves, annuli, and septa were the most common lesions detected in MS patients (80.8%) and controls (47.4%). We observed a positive correlation between sonographic diagnosis of CCSVI and the patients’ age (p = 0.003). However, such a correlation was not found in controls (p = 0.635). Notably, no significant correlations were found between sonographic signs of CCSVI and clinical characteristics of MS, except for absent flow in the jugular veins, which was found more often in primary (p<0.005) and secondary (p<0.05) progressive patients compared with non-progressive patients. Absent flow in jugular veins was significantly correlated with patients’ age (p < 0.0001). CONCLUSIONS: Sonographically defined CCSVI is common in MS patients. However, CCSVI appears to be primarily associated with the patient’s age, and poorly correlated with the clinical course of the disease
