Psychological treatment of traumatic memories in COVID-19 survivors

The COVID-19 pandemic, which has affected a significant number of individuals worldwide, is generating serious mental health issues. Recovered COVID-19 patients have experienced traumatic events related to their symptoms, isolation, possible hospitalization, bereavement, fear of infecting loved ones and the physical consequences of COVID-19. One effective psychological treatment for these patients is Eye Movement Desensitization and Reprocessing (EMDR). The aim of this paper is to describe the therapeutic intervention and effects of EMDR in a pool of COVID-19 survivors referred to an integrated psychological/psychiatric outpatient service. Twelve patients, comprising of nine males and three females, underwent EMDR psychotherapy from October 2020 to February 2022. Each patient received 8–16 weekly treatment sessions. The standard EMDR protocol of eight stages was administered to enable desensitization and reprocessing of four main targets: first positive swab, hospitalization, isolation and fear for relatives' health. Efficacy of EMDR was demonstrated by the significant improvement at clinical scale for subjective distress caused by traumatic events. For the therapists, carrying out these treatments was an intense and challenging experience. In fact, the perceived distance between therapist and patient was less defined than in other hospital settings because the pandemic affects everyone equally. However, with the widespread availability of vaccines and although the pandemic is still ongoing with the emergence of new variants, a window of improvement in the mental health landscape is starting to open up

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu
