The flying squirrels (Pteromyini, Rodentia) are the most diverse and widely distributed group of gliding mammals. Taxonomic boundaries and relationships within flying squirrels remain an area of active research in mammalogy. The discovery of new specimens of Pteromys ( Hylopetes) leonardi Thomas, 1921 previously considered a synonym of Hylopetes alboniger, in Yunnan Province, China allowed a morphological and genetic reassessment of the status of this taxon. Phylogenetic reconstruction was implemented using sequences of two mitochondrial (12S ribosomal DNA and 16S ribosomal DNA) and one nuclear (interphotoreceptor retinoid-binding protein) gene fragments. Morphological assessments involved examinations of features preserved on skins, skulls, and penises of museum specimens, supplemented with principal component analysis of craniometric data. Together these assessments revealed that this taxon should be recognized not only as a distinct species, and should also be placed within a new genus, described here as Priapomys.
The Anxiety-CHF (Anxiety in patients with Chronic Heart Failure) study investigated heart-focused anxiety (HFA, with the dimensions fear, attention, and avoidance of physical activity), general anxiety, depression, and quality of life (QoL) in patients with heart failure. Psychological measures were assessed before and up to 2years after the implantation of an implantable cardioverter defibrillator (ICD) with or without cardiac resynchronization therapy defibrillator (CRT-D).
One hundred thirty-two patients were enrolled in this monocentric prospective study (44/88 CRT-D/ICD, mean age 61±14years, mean left ventricular ejection fraction 31±9%, and 29% women). Psychological assessment was performed before device implantation as well as after 5, 12, and 24months. After device implantation, mean total HFA, HFA-fear, HFA-attention, general anxiety, and QoL improved significantly. Depression and HFA-related avoidance of physical activity did not change. CRT-D patients compared with ICD recipients and women compdered.
Angelman syndrome (AS) is a severe neurodevelopmental disorder caused by loss of function of the maternally inherited UBE3A gene in neurons. Promising disease-modifying treatments to reinstate UBE3A expression are under development and an early measure of treatment response is critical to their deployment in clinical trials. Increased delta power in EEG recordings, reflecting abnormal neuronal synchrony, occurs in AS across species and correlates with genotype. Whether delta power provides a reliable biomarker for clinical symptoms remains unknown.
We analyzed combined EEG recordings and developmental assessments in a large cohort of individuals with AS (N=82 subjects, 133 combined EEG and cognitive assessments, 1.08-28.16years; 32F) and evaluated delta power as a biomarker for cognitive function, as measured by the Bayley Cognitive Score. We examined the robustness of this biomarker to varying states of consciousness, recording techniques and analysis procedures.
Delta power predicted the Bayley Scale in emerging clinical trials.
Classical Hodgkin lymphoma (cHL) is one of the most frequently diagnosed neoplasms in young adults and is curable even in the relapse setting. Many patients seek advice regarding pregnancy once they have a sustained complete remission (CR). PD1 inhibitors are effective in inducing CRs in relapsed cHL, but little is known about their effects on pregnancy, fetal outcomes, or risk of relapse. The PD1/PDL1 axis is vital in the maintenance of pregnancy, allowing for fetal tolerance. This axis is also a key pathway by which Hodgkin Reed Sternberg cells escape immune surveillance. Thus, exposure to PD1 inhibitors in the context of a pregnant cHL survivor could potentially lead to maternal and fetal complications as well as increase the risk of relapse. Pregnancy and fetal outcomes following PD1 inhibitors have been reported in women with melanoma, but not cHL. Such data may help physicians counsel their patients on this topic.
This case describes a 25-year-old woman who was diagnosed with advanced stage cHL that was treated with multiple courses of chemotherapy and autologous stem cell transplant (ASCT) for primary refractory disease. She experienced a relapse eight months following ASCT and was treated with the PD1 inhibitor pembrolizumab. She completed a total of 21 cycles, achieving a CR after cycle five. check details After 2 years of sustained CR off pembrolizumab, she had an unassisted and uneventful pregnancy. She delivered a healthy baby boy with no significant complications. He reached his normal milestones in his first year. She remains in CR four years following her last dose of pembrolizumab, evoking the possibility of her being cured of cHL.
Successful pregnancies and fetal outcomes, while maintaining clinical remissions, are possible in women with relapsed cHL treated with pembrolizumab.

To analyse if patients with diabetic retinopathy (DR) subjected to cataract surgery differ in outcome compared to patients without DR with regard to best-corrected visual acuity (BCVA), deviation from target refraction, intraoperative difficulties and risk of complications.
A register-based study from the Swedish National Cataract Register (NCR) during the years 2015-2017 including 358040 cataract procedures. Patients with other ocular pathology than cataract and DR were omitted from outcome analyses.
Diabetic retinopathy was reported in 13724 of all eyes (3.8%). Preoperative BCVA was significantly worse in DR patients than in patients without DR, 0.54±0.33 compared to 0.40±0.27 (logMAR, mean±SD, p<0.001). The same was evident for postoperative BCVA, 0.15±0.25 for DR patients versus 0.06±0.13 (p<0.001). The improvement in BCVA was slightly better in DR than in non-DR, -0.40±0.32 (logMAR; mean±SD) versus -0.35±0.27, p<0.001. The absolute mean biometry prediction error was 0.42±0.50 diopters (D) ties and PCRs are almost twice as common in DR patients, strongly indicating that these patients should be managed by experienced surgeons.
