Weight Gain Is Associated with Medial Contact Site of Subthalamic Stimulation in Parkinson's Disease

The aim of our study was to assess changes in body-weight in relation to active electrode contact position in the subthalamic nucleus. Regular body weight measurements were done in 20 patients with advanced Parkinson's disease within a period of 18 months after implantation. T1-weighted (1.5T) magnetic resonance images were used to determine electrode position in the subthalamic nucleus and the Unified Parkinson's disease rating scale (UPDRS-III) was used for motor assessment. The distance of the contacts from the wall of the third ventricle in the mediolateral direction inversely correlated with weight gain (r = −0.55, p<0.01) and with neurostimulation-related motor condition expressed as the contralateral hemi-body UPDRS-III (r = −0.42, p<0.01). Patients with at least one contact within 9.3 mm of the wall experienced significantly greater weight gain (9.4±(SD)4.4 kg, N = 11) than those with both contacts located laterally (3.9±2.7 kg, N = 9) (p<0.001). The position of the active contact is critical not only for motor outcome but is also associated with weight gain, suggesting a regional effect of subthalamic stimulation on adjacent structures involved in the central regulation of energy balance, food intake or reward

Does company-sponsored egg freezing promote or confine women’s reproductive autonomy?

Purpose A critical ethical analysis of the initiative of several companies to cover the costs of oocyte cryopreservation for their healthy employees. The main research question is whether such policies promote or confine women’s reproductive autonomy. Results A distinction needs to be made between the ethics of AGE banking in itself and the ethics of employers offering it to their employees. Although the utility of the former is expected to be low, there are few persuasive arguments to deny access to oocyte cryopreservation to women who are well informed about the procedure and the success rates. However, it does not automatically follow that it would be ethically unproblematic for employers to offer egg banking to their employees. Conclusions For these policies to be truly ‘liberating’, a substantial number of conditions need to be fulfilled, which can be reduced to three categories: (1) women should understand the benefits, risks and limitations, (2) women should feel no pressure to take up the offer; (3) the offer should have no negative effect on other family-friendly policies and should in fact be accompanied by such policies. Fulfilling these conditions may turn out to be impossible. Thus, regardless of companies’ possible good intentions, women’s reproductive autonomy is not well served by offering them company-sponsored AGE banking
