We identified 27 cases of hepatitis A among international adoptees (5 persons), their direct or indirect contacts (20 persons), and unvaccinated travelers to the adoptees' countries (2 persons). Most cases occurred among nontraveling contacts of adoptees, suggesting the need to extend prevention guidelines to include hepatitis A vaccination for at-risk nontravelers.

Sense of coherence (SOC), with its components comprehensibility, manageability, and meaningfulness, is a major factor in the ability to cope successfully with stressors and is closely related to health. Qualitative studies related to SOC are scarce, and in this phenomenological interview study, self-care is investigated in relation to SOC. The aim of this study was to describe the lived experie...

In search of an improved strategy to form low-resistance contacts to semiconducting transition metal dichalcogenides, we combine ab initio density functional electronic structure calculations for an NbSe2/WSe2 interface with quantum transport measurements of the corresponding heterojunction between a few-layer WSe2 semiconductor and a metallic NbSe2 layer. Our theoretical results suggest that, ...

OBJECTIVE The goal of this study was to describe hepatitis A-infected adoptees and the risk of transmission to their contacts. METHODS This was a retrospective review of adoptee-associated cases of hepatitis A and hepatitis A-infected adoptees identified in Minnesota from 2007 through 2009. RESULTS From 2007 through 2009 in Minnesota, 10 cases of hepatitis A, including 1 fulminant case, wer...

Children exposed to multidrug-resistant (MDR) Mycobacterium tuberculosis are at risk of developing MDR tuberculosis. Where treatment is available, it is lengthy, expensive, and associated with poor adherence and notable morbidity and mortality. Preventive treatment effectively lowers the risk of disease progression for contacts of individuals with drug-susceptible tuberculosis, but this strateg...

I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model explains (i) the cross-sectional distribution of the number of foreign markets accessed by individual exporters, (ii) the cr...

BACKGROUND Although recently introduced directional DBS leads provide control of the stimulation field, programing is time-consuming. OBJECTIVES Here, we validate local field potentials recorded from directional contacts as a predictor of the most efficient contacts for stimulation in patients with PD. METHODS Intraoperative local field potentials were recorded from directional contacts in ...
