- INTRODUCTION AND AIM:Tinnitus is a common condition affecting approximately 20% of the older population. There is increasing evidence that changes in the central auditory system following cochlear malfunctioning are responsible for tinnitus. To date, few investigators have studied the influence of genetic factors on tinnitus. The present report investigates the presence of a familial effect in tinnitus subjects.METHODS:In a European multicentre study, 198 families were recruited in seven European countries. Each family had at least 3 siblings. Subjects were screened for causes of hearing loss other than presbyacusis by clinical examination and a questionnaire. The presence of tinnitus was evaluated with the question "Nowadays, do you ever get noises in your head or ear (tinnitus) which usually last longer than five minutes". Familial aggregation was tested using three methods: a mixed model approach, calculating familial correlations, and estimating the risk of a subject having tinnitus if the disorder is present in another family member.RESULTS:All methods demonstrated a significant familial effect for tinnitus. The effect persisted after correction for the effect of other risk factors such as hearing loss, gender and age. The size of the familial effect is smaller than that for age-related hearing impairment, with a familial correlation of 0.15.CONCLUSION:The presence of a familial effect for tinnitus opens the door to specific studies that can determine whether this effect is due to a shared familial environment or the involvement of genetic factors. Subsequent association studies may result in the identification of the factors responsible. In addition, more emphasis should be placed on the effect of role models in the treatment of tinnitus.

- The aim of this study was to analyse sick leave in generalized pustular psoriasis, the most severe form of pustular psoriasis. Prolonged sick leave of >14 days was analysed for 502 patients with generalized pustular psoriasis compared with controls with psoriasis vulgaris and matched controls from the general population. Using data from the Swedish National Patient Register, and the Longitudinal integrated database for health insurance and labour market studies, the study estimated the mean number of sick leave days in the year of first diagnosis of generalized pustular psoriasis (index year) and for 2 years before and after the index year. Patients with generalized pustular psoriasis were on sick leave to a larger extent than both control populations for all study years. The number of sick leave days peaked in the index year and then reduced. Compared with the control populations, sick leave in generalized pustular psoriasis was already higher prior to diagnosis, indicating delayed diagnosis and/or a comorbidity burden.

KIN TIES AND THE PERFORMANCE OF NEW FIRMS: A STRUCTURAL APPROACH
- 2020

- Kin ties are all but ubiquitous in new firms. However, their effects on performance are not straightforward, as they can provide new firms with advantages (enhanced coordination and cooperation) as well as disadvantages (reduced diversity, nepotism concerns, and the possible spillover of personal conflict). As kin ties may have both positive and negative implications for performance, a contingency approach to the performance of new firms is valuable. We develop such an approach by relating different structural configurations of kin ties-whether they are between founders, between founders and employees, or between employees-to the performance of new firms. We test our predictions using data on 4,967 new firms founded in Stockholm between 1998 and 2003. Our theory deepens our understanding of why kin ties have heterogeneous effects on the performance of new firms.
