Long-term effect of apomorphine infusion in advanced Parkinson's disease: a real-life study.

NPJ Parkinsons Dis 2021 Jun 11;7(1):50. Epub 2021 Jun 11.

Long-term effects of continuous subcutaneous apomorphine infusion (CSAI) on health-related quality of life (HRQoL) and predictors of CSAI discontinuation are poorly known. Data from consecutive advanced Parkinson's disease patients treated in routine care were retrospectively collected over 24 months after CSAI initiation, with a focus on the 39-item Parkinson's disease questionnaire (PDQ-39). We determined predictors of CSAI discontinuation and HRQoL improvement using multiple regression analysis. Of the 110 subjects evaluated over a 2-year period, 35% discontinued CSAI. Of those who continued treatment, HRQoL remained stable with a sustained reduction in motor fluctuations. The observed effect on dyskinesias was mild and transient. Of note, patients with preexisting impulse control disorders showed an overall good tolerability. PDQ-39 was the only baseline predictor of HRQoL improvement after 2 years of treatment. The presence of dyskinesias, poorer psychological status, shorter disease duration, male sex, and worse OFF state were predictors of discontinuation. Best candidates for CSAI are patients with: (i) poor baseline HRQoL and (ii) marked motor fluctuations.

NeuroQ: A neurophobia screening tool assesses how roleplay challenges neurophobia.

J Neurol Sci 2021 Feb 20;421:117320. Epub 2021 Jan 20.

AP-HP, Hôpital Pitié-Salpêtrière, Département de Neurologie, Paris, France; Sorbonne Université, France; INSERM U1127, CNRS 7225, Institut du Cerveau, Paris, France.

Background: Neurophobia is a chronic disease of medical students and junior doctors. Early detection is needed to facilitate prevention and management as this fear can negatively impact patient care.

Methods: We conducted a two-part mono-centric study at the faculty of Medicine, Sorbonne University, in Paris. Part one: a cross-sectional study to validate a newly constructed neurophobia scale, NeuroQ. Part two: a prospective longitudinal study to assess the impact of The Move on student neurophobia using NeuroQ. A population-based sample of second-year medical students of the 2019 and 2020 class of the Faculty of Medicine of Sorbonne University were invited to participate.

Results: NeuroQ incorporates the main themes of the neurophobia definition and demonstrates uni-dimensionality. Three hundred and ninety-five medical students participated in the study (mean age was 20.0 years, SD: 2.1 years) assessing the effect of The Move teaching on neurophobia. Two hundred and eighty-eight (72.9%) students were female. After the Move teaching the mean NeuroQ score was significantly lower compared to the baseline NeuroQ score (mean [SD] variation, -1.1 [2.6], p < 0.001). There was a 22.3% relative reduction in the number of neurophobic students after The Move teaching.

Conclusion: Our results highlight the utility of NeuroQ in assessing (i) baseline neurophobia and (ii) the impact of pre-clinical educational interventions on neurophobia. Furthermore, we have shown the importance of pre-clinical educational interventions, such as The Move, in tackling neurophobia.

Functional dissection of the splice variants of the Drosophila gene homothorax (hth).

Dev Biol 2013 Dec 25;384(1):72-82. Epub 2013 Sep 25.

Homothorax belongs to the TALE-homeodomain family of transcription factors, together with its vertebrate counterparts, the Meis family of proto-oncogenes. It fulfills many important different functions during embryonic and larval developments in Drosophila, which encompass from subdivision and specification of body parts to assembly of heterochromatin structures. Hth interacts with Extradenticle, another member of the TALE-homeodomain family of conserved transcription factors, to facilitate its entrance to the nucleus. The many different functions described for Hth rely on the complexity of the locus, from which six different isoforms arise. The isoforms can be grouped into full-length and short versions, which contain either one or the two conserved domains of the protein (homeodomain and Exd-interacting domain). We have used molecular and genetic tools to analyze the levels of expression, the distribution and the function of the isoforms during embryonic development. Our results clearly show that the isoforms display distinct levels of expression and are differentially distributed in the embryo. This detailed study also shows that during normal embryonic development not all the Hth isoforms translocate Exd into the nucleus, suggesting that both the proteins can also function separately. We have demonstrated that the full-length Hth protein activates transcription of exd, augmenting the levels of exd mRNA in the cell. The higher levels of Exd protein in those cells facilitate its entrance to the nucleus. Our work demonstrates that hth is a complex gene that should not be considered as a functional unit. The roles of the different isoforms probably rely on their distinct protein domains and conformations and, at the end, on interactions with particular partners.

A new role for hth in the early pre-blastodermic divisions in drosophila.

Cell Cycle 2009 Sep 29;8(17):2748-55. Epub 2009 Sep 29.

Centro de Biología Molecular Severo Ochoa, CSIC-UAM, Universidad Autónoma de Madrid, Madrid, Spain.

In drosophila, the preblastodermic syncytial nuclear divisions occur very fast. In this short period of time chromosomes must condense, segregate and decondense, in conditions governed by maternally provided RNAs and proteins. In this report, we show that the Homothorax (Hth) transcription factor is maternally provided and that its function is necessary for the proper assembly of the centric/centromeric heterochromatin during preblastodermic divisions. Embryos lacking the hth maternally-derived transcript, show abnormal localisation of the centromeric CID protein, and aberrant chromosomal segregation. In this syncytial context, Hth presumably acts together with its partner Extradenticle (Exd) and the RNA PolII, to facilitate transcription of satellite repeats. The transcripts derived from these sequences are needed for the correct assembly of the centric heterochromatin.
