Seminar on the dual unity and the phantom.

“Seminar on the Dual Unity and the Phantom” translates into English Nicolas Abraham’s notes from a presentation series delivered at the Société psychanalytique de Paris in 1974-5. These were collected as a single essay and published in French by his partner Maria Torok following Abraham’s untimely death in 1975. The Seminar introduces the dual unity as a clinical concept to account for patient symptomatology where traumatic structures resist intervention and are seemingly impossible to locate. Abraham describes these pathologies in terms of a phantom; the transmission down generations of gaps and silences in comprehension that disrupt emerging subjectivity at its foundation. Abraham demonstrates through a number of clinical and fictional cases how phantoms are transferred unwittingly into an individual psyche and uses this to pose questions about the boundaries of selfhood that extend beyond his pathological examples. As a broader metapsychological concept, the dual unity explains the mechanisms of self-formation in general terms as the always incomplete separation of an individual from the maternal context. Abraham conceives of selfhood as a symbolic response to and overcoming of the traumas that characterize human existence, which begin with the loss(es) of the mother. He describes the birth of the subject, therefore, as the accession to symbolic life through words split off from the maternal context and used to designate objects in the outside world. The words, however, still retain traces of that first relationship in the connection they draw to the drama of separation and the maternal unconscious that haunts this scission as the protector and a danger to individuation. The duality of the mother-child relationship is transformed through the objective use of words into a relation between the shared meaning of language (understood at the level of ego) and a “whole stratification of maternal imagos” that constitute the individual unconscious and whose traces inhabit those same words. This constant connection to the mother means we are always separate-unseparated beings; dual unities open to the continual threat of haunting

Patient and healthcare provider experience and perceptions of a preoperative rehabilitation class for lumbar discectomy: A qualitative study

Background: Lumbar disc disease is a leading cause of low back pain. Lumbar discectomy (LD) may be indicated if symptoms are not managed conservatively. Rehabilitation has traditionally been delivered postoperatively; however, there is increasing delivery preoperatively. There are few data concerning perceptions and experiences of preoperative rehabilitation. Exploring experiences of preoperative rehabilitation may help in the development and delivery of effective care for patients. Objectives: To develop an understanding of patient and healthcare provider (HCP) experiences, perspectives and preferences of preoperative LD rehabilitation, including why patients do not attend. Design: A qualitative interpretive approach using focus groups and individual interviews. Methods: Data were collected from; a) patients listed for surgery and attended the preoperative rehabilitation (October 2019 to March 2020), b) patients listed for surgery but did not attend rehabilitation, and c) HCPs involved in the delivery of rehabilitation. Data were transcribed verbatim and analysed using thematic analysis. Results/findings: Twenty participants were included, twelve patients and eight HCPs. The preoperative class was a valuable service for both patients and HCPs. It provided a solution to staffing and time pressures. It provided the required education and exercise content helping the patients along their surgery pathway. Travel distance, transportation links, parking difficulty and cost, lack of knowledge about the class aims, and previous negative experiences were barriers to patient attendance. Conclusions: For most patients and HCPs, the preoperative class was valuable. Addressing the challenges and barriers could improve attendance. Future research should focus on management of patient expectations and preferences preoperatively

A new purple sulfur bacterium from saline littoral sediments, Thiorhodotvibrio winogradskyi gen. nov. and sp. nov.

Two strains of a new purple sulfur bacterium were isolated in pure culture from the littoral sediment of a saline lake (Mahoney Lake, Canada) and a marine microbial mat from the North Sea island of Mellum, respectively. Single cells were vibrioid-to spirilloid-shaped and motile by means of single polar flagella. Intracellular photosynthetic membranes were of the vesicular type. As photosynthetic pigments, bacteriochlorophyll a and the carotenoids lycopene, rhodopin, anhydrorhodovibrin, rhodovibrin and spirilloxanthin were present. Hydrogen sulfide and elemental sulfur were used under anoxic conditions for phototrophic growth. In addition one strain (06511) used thiosulfate. Carbon dioxide, acetate and pyruvate were utilized by both strains as carbon sources. Depending on the strain propionate, succinate, fumarate, malate, tartrate, malonate, glycerol or peptone may additionally serve as carbon sources in the light. Optimum growth rates were obtained at pH 7.2, 33 °C, 50 mol m-2 s-1 intensity of daylight fluorescent tubes and a salinity of 2.2–3.2% NaCl. During growth on sulfide, up to ten small sulfur globules were formed inside the cells. The strains grew microaerophilic in the dark and exhibited high specific respiration rates. No vitamins were required for growth. The DNA base composition was 61.0–62.4 mol% G+C. The newly isolated bacterium belongs to the family chromatiaceae and is described as a member of a new genus and species, Thiorhodovibrio winogradskyi gen. nov. and sp. nov. with the type strain SSP1, DSM No. 6702

Excess Mortality Rate During Adulthood Among Danish Adoptees

BACKGROUND AND OBJECTIVE: Adoption studies have been used to disentangle the influence of genes from shared familial environment on various traits and disease risks. However, both the factors leading to adoption and living as an adoptee may bias the studies with regard to the relative influence of genes and environment compared to the general population. The aim was to investigate whether the cohort of domestic adoptees used for these studies in Denmark is similar to the general population with respect to all-cause mortality and cause-specific mortality rates. METHODS: 13,111 adoptees born in Denmark in 1917, or later, and adopted in 1924 to 1947 were compared to all Danes from the same birth cohorts using standardized mortality ratios (SMR). The 12,729 adoptees alive in 1970 were similarly compared to all Danes using SMR as well as cause-specific SMR. RESULTS: The excess in all-cause mortality before age 65 years in adoptees was estimated to be 1.30 (95% CI 1.26-1.35). Significant excess mortality before age 65 years was also observed for infections, vascular deaths, cancer, alcohol-related deaths and suicide. Analyses including deaths after age 65 generally showed slightly less excess in mortality, but the excess was significant for all-cause mortality, cancer, alcohol-related deaths and suicides. CONCLUSION: Adoptees have an increased all-cause mortality compared to the general population. All major specific causes of death contributed, and the highest excess is seen for alcohol-related deaths

Detailed Structural Analysis of Lipids Directly on Tissue Specimens Using a MALDI-SpiralTOF-Reflectron TOF Mass Spectrometer

Direct tissue analysis using a novel tandem time-of-flight (TOF-TOF) mass spectrometer is described. This system consists of a matrix-assisted laser desorption/ionization ion source, a spiral ion trajectory TOF mass spectrometer “SpiralTOF (STOF)”, a collision cell, and an offset parabolic reflectron (RTOF). The features of this system are high precursor ion selectivity due to a 17-m flight path length in STOF and elimination of post-source decay (PSD) ions. The acceleration energy is 20 keV, so that high-energy collision-induced dissociation (HE-CID) is possible. Elimination of PSD ions allows observation of the product ions inherent to the HE-CID process. By using this tandem TOF instrument, the product ion spectrum of lipids provided detailed structural information of fatty acid residues
