This paper attempts to read the psychological and emotional impact of the COVID-19 pandemic through the archetypal images contained in patients' dreams. In these dreams, symbols related to the power of nature and to extreme danger are paired with feelings of detachment that seem to point to a traumatic dissociation, due to the archetypal experience that erupts in familiar surroundings. Through the humanization of the ineffable experience, dissociation, which in the beginning of the pandemic showed in high levels of anxiety, panic attacks and depersonalization, can be transformed into the overview needed for the search for meaning. The container for this process of transformation is the analyst, the real, virtual or imagined one, and his or her ability to relate and feel.

The implementation of skills labs in Danish nursing education can, in itself, be viewed as a complexity. The students are expected to eventually carry out their work in a situated hospital practice, but they learn their professional skills in a different space altogether, detached and removed from the hospitals and practising on plastic dummies. Despite the apparent artificiality of the skills lab, this article will show that it is possible to analyse some of the fundamental aspects of care in nursing by ethnographically following this phenomenon of simulation-based training. These particular aspects of care are not explicated in the curriculum or textbooks; however, they surfaced once this crooked approach to studying care in a simulated practice was applied. The article start from the assertion that detached engagements are not recognized within the field of nursing education as an equal component to attachments. Yet empirical cases from the skills lab and hospitals illustrate how students sometimes felt emotionally attached to plastic dummies and how experienced nurses sometimes practised a degree of detachment in relation to human patients. Detached engagements will therefore be presented as part of care practices of nurses - rendering the ability to detach in engagement with patients a professional skill that students also need to learn. In the analysis to follow, attached and detached engagements are located on an equal plane by integrating both into the same conceptual framework, rather than imposing a priori notions about their dialectic relation. The analysis shows that it is the particular intertwinement of attachment and detachment that gives care its fundamental meaning. In conclusion, the need for a conceptual shift from a strong emphasis on attached engagement to a more balanced analytical approach to care work, as involving both attached and detached engagement within Danish nursing education, is advocated.

Review
With modern surgical techniques to repair retinal detachments, a greater than 90% primary anatomic success rate can be expected. Despite this high level of anatomic success, visual results remain compromised mainly because of permanent functional damage once the macula becomes detached. The most important predictor of visual recovery after retinal detachment surgery is preoperative visual acuity. Preoperative acuity appears to be directly related to the height of macular detachment. Shorter duration of detachment and younger age are also important in visual recovery. This paper will review the current literature that helps to improve our understanding of visual recovery after macula-off retinal detachments.

Collaborative robots promise to add flexibility to production cells thanks to the fact that they can work not only humans but also humans. The possibility of a direct physical interaction between humans and robots allows to perform operations that were inconceivable with industrial robots. Collaborative soft grippers have been recently introduced to extend this possibility beyond the robot end-effector, making humans able to directly act on robotic hands. In this work, we propose to exploit collaborative grippers in a novel paradigm in which these devices can be easily attached and detached from the robot arm and used also independently from it. This is possible only with self-powered hands, that are still quite uncommon in the market. In the presented paradigm not only hands can be attached/detached to/from the robot end-effector as if they were simple tools, but they can also remain active and fully functional after detachment. This ensures all the advantages brought in by tool changers, that allow for quick and possibly automatic tool exchange at the robot end-effector, but also gives the possibility of using the hand capabilities and degrees of freedom without the need of an arm or of external power supplies. In this paper, the concept of is introduced and demonstrated through two illustrative tasks conducted with a new tool changer designed for collaborative grippers. The novel tool changer embeds electromagnets that are used to add safety during attach/detach operations. The activation of the electromagnets is controlled through a wearable interface capable of providing tactile feedback. The usability of the system is confirmed by the evaluations of 12 users.

Review
Traditional techniques for managing uncomplicated macula-sparing rhegmatogenous retinal detachments include scleral buckling and pneumatic retinopexy. Demarcation laser photocoagulation is associated with less morbidity than these techniques and may be equally as effective in stabilizing selected macula-sparing retinal detachments.

Epithelial tissues function as barriers that separate the organism from the environment. They usually have highly curved shapes, such as tubules or cysts. However, the processes by which the geometry of the environment and the cell's mechanical properties set the epithelium shape are not yet known. In this study, we encapsulated two epithelial cell lines, MDCK and J3B1A, into hollow alginate tubes and grew them under cylindrical confinement forming a complete monolayer. MDCK monolayers detached from the alginate shell at a constant rate, whereas J3B1A monolayers detached at a low rate unless the tube radius was reduced. We showed that this detachment is driven by contractile stresses in the epithelium and can be enhanced by local curvature. This allows us to conclude that J3B1A cells exhibit smaller contractility than MDCK cells. Monolayers inside curved tubes detach at a higher rate on the outside of a curve, confirming that detachment is driven by contraction.

Meters of DNA wrap around histone proteins to form nucleosomes and fit inside the micron-diameter nucleus. For the genetic information encoded in the DNA to become available for transcription, replication, and repair, the DNA-histone assembly must be disrupted. Experiment has indicated that the outer stretches of nucleosomal DNA "breathe" by spontaneously detaching from and reattaching to the histone core. Here, we report direct observation of spontaneous DNA breathing in atomistic molecular dynamics simulations, detailing a microscopic mechanism of the DNA breathing process. According to our simulations, the outer stretches of nucleosomal DNA detach in discrete steps involving 5 or 10 base pairs, with the detachment process being orchestrated by the motion of several conserved histone residues. The inner stretches of nucleosomal DNA are found to be more stably associated with the histone core by more abundant nonspecific DNA-protein contacts, providing a microscopic interpretation of nucleosome unraveling experiments. The CG content of nucleosomal DNA is found to anticorrelate with the extent of unwrapping, supporting the possibility that AT-rich segments may signal the start of transcription by forming less stable nucleosomes.

Review
Pneumatic retinopexy (PR) is an alternative to scleral buckling for the surgical repair of selected retinal detachments. A gas bubble is injected into the vitreous cavity, and the patient is positioned so that the bubble closes the retinal break (s), allowing absorption of the subretinal fluid. Cryotherapy or laser photocoagulation is applied around the retinal break(s) to form a permanent seal. The procedure can be done in an outpatient setting, and no incisions are required. A multicenter randomized controlled clinical trial has demonstrated that the anatomic success rate is comparable to scleral buckling, but the morbidity is significantly less with PR. If the macula was detached for less than two weeks, the visual results are significantly better with PR than with scleral buckling. Cataract surgery was required significantly more often following scleral buckling than following PR. Two independent reports have shown that an attempt with PR does not disadvantage the eye; such that the results of scleral buckling after failed PR are not significantly different than primary scleral buckling. A comprehensive review of the world literature on PR revealed 27 statistical series totaling 1,274 eyes. These combined series had a single-operation success rate of 80%, and 98% were cured with reoperations. Pneumatic retinopexy should be considered in cases without inferior or extensive retinal breaks and without significant proliferative vitreoretinopathy. The cost of buckling varies from 4 to 10 times that of PR.

Comparative Study
Biofilm-detached cells, a transition from a sessile to a planktonic phenotype: a comparative study of adhesion and physiological characteristics in Pseudomonas aeruginosa.
Pseudomonas aeruginosa is a pathogenic bacterium widely investigated for its high incidence in clinical environments and its ability to form strong biofilms. During biofilm development, sessile cells acquire physiological characteristics differentiating them from planktonic cells. But after treatment with disinfectants, or to ensure survival of the species in hostile environments, biofilm cells can detach. This complicates disinfection procedures. This study aimed to physiologically characterize cells detached from a P. aeruginosa biofilm and to compare them with their sessile and planktonic counterparts. We first tested planktonic growth kinetics and capacities to form new biofilms. Then we investigated cell-surface properties. And finally, we tested in vitro susceptibility to antibiotics. The results first indicated that sessile and detached cells have similar planktonic growth kinetics and cell-surface properties, distinguishable from those of planktonic cells. Interestingly, the three populations exhibited different biofilm-forming capacities, suggesting that there is a transitional phenotype between sessile and planktonic states, at least during the first hours following cell detachment. It is important to consider this observation when developing treatments to optimize disinfection processes. Surprisingly, the three populations showed the same antibiotic susceptibility profile.
