Emotions, Stress and Coping among Healthcare Workers in a Reproductive Medicine Unit during the First and Second COVID-19 Lockdowns.

The impact of the COVID-19 pandemic on global healthcare workers' (HCWs) mental health has been well documented in the last two years; however, little is known regarding HCWs working in specific healthcare fields. During two subsequent periods of national lockdown in Italy (June-July 2020, T1, and November-December 2020, T2), a total sample of 47 HCWs working in a reproductive medicine hospital unit completed an ad hoc questionnaire for assessing emotional reactions to the pandemic, stress symptoms, and ways of coping. Moderate-high levels of anger and sadness were experienced by 65.9% and 68.1% of the HCWs, respectively, while moderate-high levels of anxiety and fear were experienced by 51.1% and 56.8%, respectively. Higher stress symptoms experienced by HCWs were hypervigilance, avoidance of thoughts and memories, and tiredness/low energy. At T2, levels of hypervigilance, irritability, intrusive thoughts, and detachment were higher than at T1, while avoidance of external triggers decreased. Moderate-high levels of anxiety resulted significantly associated with several symptoms of stress: irritability/fearfulness, depression/hopelessness, tiredness/low energy, problems with concentration, and intrusive thoughts. Regarding coping strategies, HCWs tended to adopt more problem-focused coping (e.g., contributing to improving a situation) and this tendency was higher at T2. Overall findings suggest a risk for the persistence of stress symptoms and, therefore, a risk for a chronic course, which might interfere with the global quality of mental health at work and the care provided to patients. Clinical implications highlight the relevance of implementing support programs for this category of HCWs focused on the elaboration of negative emotions and on fostering adaptive coping strategies.

Maternal and Paternal Representations in Assisted Reproductive Technology and Spontaneous Conceiving Parents: A Longitudinal Study.

Aim of this study was to investigate whether parental mental representations during pregnancy and after delivery differed between parents who conceived after Assisted Reproductive Treatments (ART) and spontaneous conceiving (SC) parents. Effects of specific ART variables (previous ART attempts, treatment type and cause of infertility) were also taken into account. Seventeen ART couples and 25 SC couples were recruited at Santa Maria Nuova Hospital (Reggio Emilia, Italy). At both 32 weeks of gestation (T1) and 3 months postpartum (T2) participants completed the Semantic Differential of the IRMAG, a self-report tool which measures specific domains of mental representations pertaining either individual (Child, Self-as-woman/man, and Partner) or parental (Self-as-parent, Own parent) characteristics. Results showed that ART parents had significantly more positive representations of the child compared to SC parents, while the scores at Partner dimension improved from T1 to T2 for SC parents only. With regards to ART history, scores at the Self-as-woman/man dimension were significantly less positive for ICSI than IVF parents and improved substantially from T1 to T2 only in case of mothers with previous ART attempts and of fathers at the first ART cycle. The representation of own parents increased from T1 to T2 in case of infertility diagnosis due to male factors, while a decrease emerged when infertility was due to female factors. Findings suggest the need to investigate parental mental representations after ART, in order to improve the understanding on the transition to parenthood of infertile couples and to target more specific intervention for parenting support.

A Ligand-Based NMR Screening Approach for the Identification and Characterization of Inhibitors and Promoters of Amyloid Peptide Aggregation.

Over the years a significant amount of effort has been put into the development of rapid and reliable methods to monitor the aggregation dynamics of the ß1-42 amyloid peptide in real time. We present an alternative approach based on a suitable reporter or spy molecule and three different NMR experiments: WaterLOGSY, 1 H selective T1 filter, and 19 F T2 filter, for monitoring the initial self-aggregation process kinetics of the ß1-42 amyloid peptide and identifying molecules that retard or accelerate the self-aggregation process. Although the proposed method is not a high-throughput assay, it avoids problems associated with interference events that are sometimes observed in fluorescence-based assays.

Mismatch Negativity Recording in Children With Duchenne Muscular Dystrophy: A Preliminary Study Integrating Neurophysiological and Neuropsychological Results.

Many studies on Duchenne muscular dystrophy children support the hypothesis of a specific neuropsychological phenotype affecting mostly phonological skills. This prospective study aimed to shed light on the role of phonological abilities. Fourteen Duchenne muscular dystrophy children and 7 healthy children underwent mismatch negativity. Moreover, verbal intelligence, visuospatial attention, immediate verbal memory, working memory, grammar, vocabulary, visuomotor skills, reading, text comprehension, writing, and arithmetic were tested in Duchenne muscular dystrophy children. No significant difference between control and Duchenne muscular dystrophy children was found neither for mismatch negativity amplitude (P = .191 and .116, respectively) nor for latency (P = .135). Eight (57.14%) patients showed an impairment of immediate verbal memory and of visuomotor skills, 7 (63.64%) patients had a deficit in writing and arithmetic skills, even with a mean normal intelligence quotient. Taken together, the results put in evidence a heterogeneous neuropsychological profile not explainable on the basis of a phonological deficit.

Real-time amyloid aggregation monitoring with a photonic crystal-based approach.

We propose the application of a new label-free optical technique based on photonic nanostructures to real-time monitor the amyloid-beta 1-42 (Aß(1-42)) fibrillization, including the early stages of the aggregation process, which are related to the onset of the Alzheimer's Disease (AD). The aggregation of Aß peptides into amyloid fibrils has commonly been associated with neuronal death, which culminates in the clinical features of the incurable degenerative AD. Recent studies revealed that cell toxicity is determined by the formation of soluble oligomeric forms of Aß peptides in the early stages of aggregation. At this phase, classical amyloid detection techniques lack in sensitivity. Upon a chemical passivation of the sensing surface by means of polyethylene glycol, the proposed approach allows an accurate, real-time monitoring of the refractive index variation of the solution, wherein Aß(1-42) peptides are aggregating. This measurement is directly related to the aggregation state of the peptide throughout oligomerization and subsequent fibrillization. Our findings open new perspectives in the understanding of the dynamics of amyloid formation, and validate this approach as a new and powerful method to screen aggregation at early stages.

An unusual case report on the possible role of Warfarin in migraine prophylaxis.

BACKGROUND: Migraine is a complex disease whose physiopathological mechanisms are still not completely revealed. FINDINGS: We describe an unusual case, not yet described in literature, of a patient who reported migraine remission, but still presented aura attacks, since starting a therapy with Warfarin. CONCLUSIONS: This case report brings out new questions on the role of the coagulation, especially the blood coagulation pathway, in migraine with aura pathogenesis, and on the possibility to use vitamin K synthesis inhibitors, Warfarin or new generation drugs, as possible therapy to use in migraine prophylaxis.
