COVID-19 in patients with thoracic malignancies (TERAVOLT): first results of an international, registry-based, cohort study
Background: Early reports on patients with cancer and COVID-19 have suggested a high mortality rate compared with the general population. Patients with thoracic malignancies are thought to be particularly susceptible to COVID-19 given their older age, smoking habits, and pre-existing cardiopulmonary comorbidities, in addition to cancer treatments. We aimed to study the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on patients with thoracic malignancies.
Methods: The Thoracic Cancers International COVID-19 Collaboration (TERAVOLT) registry is a multicentre observational study composed of a cross-sectional component and a longitudinal cohort component. Eligibility criteria were the presence of any thoracic cancer (non-small-cell lung cancer [NSCLC], small-cell lung cancer, mesothelioma, thymic epithelial tumours, and other pulmonary neuroendocrine neoplasms) and a COVID-19 diagnosis, either laboratory confirmed with RT-PCR, suspected with symptoms and contacts, or radiologically suspected cases with lung imaging features consistent with COVID-19 pneumonia and symptoms. Patients of any age, sex, histology, or stage were considered eligible, including those in active treatment and clinical follow-up. Clinical data were extracted from medical records of consecutive patients from Jan 1, 2020, and will be collected until the end of pandemic declared by WHO. Data on demographics, oncological history and comorbidities, COVID-19 diagnosis, and course of illness and clinical outcomes were collected. Associations between demographic or clinical characteristics and outcomes were measured with odds ratios (ORs) with 95% CIs using univariable and multivariable logistic regression, with sex, age, smoking status, hypertension, and chronic obstructive pulmonary disease included in multivariable analysis. This is a preliminary analysis of the first 200 patients. The registry continues to accept new sites and patient data.
Findings: Between March 26 and April 12, 2020, 200 patients with COVID-19 and thoracic cancers from eight countries were identified and included in the TERAVOLT registry; median age was 68·0 years (61·8-75·0) and the majority had an Eastern Cooperative Oncology Group performance status of 0-1 (142 [72%] of 196 patients), were current or former smokers (159 [81%] of 196), had non-small-cell lung cancer (151 [76%] of 200), and were on therapy at the time of COVID-19 diagnosis (147 [74%] of 199), with 112 (57%) of 197 on first-line treatment. 152 (76%) patients were hospitalised and 66 (33%) died. 13 (10%) of 134 patients who met criteria for ICU admission were admitted to ICU; the remaining 121 were hospitalised, but were not admitted to ICU. Univariable analyses revealed that being older than 65 years (OR 1·88, 95% 1·00-3·62), being a current or former smoker (4·24, 1·70-12·95), receiving treatment with chemotherapy alone (2·54, 1·09-6·11), and the presence of any comorbidities (2·65, 1·09-7·46) were associated with increased risk of death. However, in multivariable analysis, only smoking history (OR 3·18, 95% CI 1·11-9·06) was associated with increased risk of death.
Interpretation: With an ongoing global pandemic of COVID-19, our data suggest high mortality and low admission to intensive care in patients with thoracic cancer. Whether mortality could be reduced with treatment in intensive care remains to be determined. With improved cancer therapeutic options, access to intensive care should be discussed in a multidisciplinary setting based on cancer specific mortality and patients' preference

Operationalizing mild cognitive impairment criteria in small vessel disease: The VMCI-Tuscany Study
Introduction Mild cognitive impairment (MCI) prodromic of vascular dementia is expected to have a multidomain profile. Methods In a sample of cerebral small vessel disease (SVD) patients, we assessed MCI subtypes distributions according to different operationalization of Winblad criteria and compared the neuroimaging features of single versus multidomain MCI. We applied three MCI diagnostic scenarios in which the cutoffs for objective impairment and the number of considered neuropsychological tests varied. Results Passing from a liberal to more conservative diagnostic scenarios, of 153 patients, 5% were no longer classified as MCI, amnestic multidomain frequency decreased, and nonamnestic single domain increased. Considering neuroimaging features, severe medial temporal lobe atrophy was more frequent in multidomain compared with single domain. Discussion Operationalizing MCI criteria changes the relative frequency of MCI subtypes. Nonamnestic single domain MCI may be a previously nonrecognized type of MCI associated with SVD
The impact of gender norms on female work choices and entrepreneurship in Kenya
The thesis investigates the impact of a society's prevalent gender ideology on women's work decisions and entrepreneurial choices, in the context of Kenya. It begins by setting up a conceptual framework that accounts for the role of gender institutions, which integrates contributions from institutional and behavioural economics and social psychology. Using a nationally representative database I test a set of econometric models of occupational choice. Measures of gender institutions include conventional proxies (like religion and ethnicity), but also innovative proxies like female circumcision, son preference, and gender parity in education. The results show that traditional gender role attitudes are important determinants of women's decisions to work and affect their choice between working within and outside the house. In order to bring into the analysis the impact of social norms on individual women, I also introduce exogenous indexes of personal autonomy, which I construct on the basis of theoretical work on female empowerment and employing different methodologies (namely, as summary indexes and as principal component analytical measures). One interesting result is that women who have higher decisional power may not prefer working, and this result stimulates a reflection on feminist and development literature that assumes that female work is instrumental to women's liberation in any context. Primary data collected during field work are used to test another set of econometric models, which analyse specific entrepreneurial decisions (diversification and formality), and business earnings. The results suggest that differently from men, women who diversify have top educational levels and run relatively good businesses. I argue that women may prefer diversifying because they lack control over the assets needed to expand the existing activity, and because their primary concern may be survival rather than growth. Formality of female firms depends on ability to keep regular accounts and create networks, which may provide capital but also knowledge and information. Finally, while whether women diversify and formalise depend upon gender institutions, how much they earn from the businesses depends (as for men) on purely economic resources.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
