Simultaneous activation of different subtypes of dopamine receptors may lead to activation of homeostatic sleep regulatory mechanisms.

Dopaminergic system gains importance in homeostatic sleep regulation, but the role of different dopamine receptors is not well-defined. 72 h rat electrocorticogram and sleep recordings were made after single application of dopaminergic drugs in clinical use or at least underwent clinical trials. The non-selective agonist apomorphine evoked short pharmacological sleep deprivation with intense wakefulness followed by pronounced sleep rebound.

Introduction: In the advanced stages of Parkinson's disease (PD), when standard drug adjustments fail to sufficiently improve patients' quality of life, device-aided therapies (DATs) such as deep brain stimulation (DBS), continuous subcutaneous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel infusion (LCIG), levodopa-carbidopa-entacapone intestinal gel infusion, or continuous subcutaneous foslevodoa-foscarbidopa infusion are beneficial in the long run. However, sometimes patients need to switch or combine DATs due to either adverse events or loss of efficacy.
Aim Of Study: The aim of this article was to summarise the existing data on the long-term efficacy and adverse events of DATs, and to review the data on the rationale and efficacy for switching or combining DATs in advanced PD.
How well is the female population represented in clinical trials with infusion therapies for Parkinson's disease? A systematic review and metanalysis.

Background: Parkinson's disease (PD) is a neurodegenerative disorder affecting both sexes, but differences exist between male and female in clinical manifestations, functional impact of symptoms and hormonal influences. Therefore, representativeness of females in PD trials indirectly determines the external validity of the clinical research in this field.
Objective: To estimate the representativeness of female in infusion therapy trials for advanced PD.
Systemically circulating 17β-estradiol enhances the neuroprotective effect of the smoking cessation drug cytisine in female parkinsonian mice.

The smoking cessation drug cytisine exerts neuroprotection in substantia nigra pars compacta (SNc) dopaminergic (DA) neurons of female but not male 6-hydroxydopamine (6-OHDA) lesioned parkinsonian mice. To address the important question of whether circulating 17β-estradiol mediates this effect, we employ two mouse models aimed at depleting systemically circulating 17β-estradiol: (i) bilateral ovariectomy (OVX), and (ii) aromatase inhibition with systemically administered letrozole. In both models, depleting systemically circulating 17β-estradiol in female 6-OHDA lesioned parkinsonian mice results in the loss of cytisine-mediated neuroprotection as measured using apomorphine-induced contralateral rotations and SNc DA neurodegeneration.

Introduction: In Poland, not all forms of device-aided therapies for advanced Parkinson's Disease (APD) are currently available.
Material And Methods: We aimed to produce a consensus recommendation from Polish movement disorders experts after discussing gaps in the APD care pathway in Poland.
Results: Rescue therapy with apomorphine (APO) PEN injection and levodopa-entacapone-carbidopa intestinal gel infusion are not included in Poland's Specialist Therapeutic Programme, and are thus not reimbursed.
