Measurement phase transitions in the no-click limit as quantum phase transitions of a non-hermitean vacuum

We study dynamical phase transitions occurring in the stationary state of the dynamics of integrable many-body non-hermitian Hamiltonians, which can be either realized as a no-click limit of a stochastic Schr\"{o}dinger equation or using spacetime duality of quantum circuits. In two specific models, the Transverse Field Ising Chain and the Long Range Kitaev Chain, we observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian: bounded entanglement entropy when the imaginary part of the quasi-particle spectrum is gapped and a logarithmic growth for gapless imaginary spectrum. This observation suggests the possibility to generalize the area-law theorem to non-Hermitian Hamiltonians.Comment: v1:23 pages, 9 figures; v2: Unchanged results.

Effects of the COVID-19 Epidemic on Hospital Admissions for Non-Communicable Diseases in a Large Italian University-Hospital: A Descriptive Case-Series Study

Background: Concern is growing about the negative consequences that response measures to the COVID-19 epidemic may have on the management of other medical conditions. Methods: A retrospective descriptive case-series study conducted at a large University-hospital in northern Italy, an area severely hit by the epidemic. Results: Between 23 February and 14 May 2020, 4160 (52%) COVID-19 and 3778 (48%) non-COVID-19 patients were hospitalized. COVID-19 admissions peaked in the second half of March, a period characterized by an extremely high mortality rate (27.4%). The number of admissions in 2020 was similar to 2019, but COVID-19 patients gradually occupied all available beds. Comparison between COVID-19 and non-COVID-19 admissions in 2020 revealed significant differences concerning all age classes and gender. Specifically, COVID-19 patients were older, predominantly male, and exhibited more comorbidities. Overall, admissions for non-communicable diseases (NCDs) in 2020 vs. 2019 dropped by approximately one third. Statistically significant reductions were observed for acute myocardial infarction (−78, −33.9%), cerebrovascular disease (−235, −41.5%), and cancer (−368, −31.9%). While the first two appeared equally distributed between COVID-19 and non-COVID-19 patients, chronic NCDs were statistically significantly more frequent in the former, except cancer, which was less frequent in COVID-19 patients. Conclusions: Prevention of collateral damage to patients with other diseases should be an integral part of epidemic response plans. Prospective cohort studies are needed to understand the long-term impact

"Uma vida lida" : Bernardo Soares, um intérprete da realidade no Livro do desassossego

Este trabalho tem como foco analisar a genologia do Livro do Desassossego de Fernando Pessoa (Vicente Guedes/Fernando Pessoa/Bernardo Soares), aproximando essa obra ao gênero literário romance. Para isso, busca se mostrar como Pessoa cria um personagem complexo, o narrador protagonista, e estrutura sua ficção com as técnicas experimentais introduzidas na literatura pelos modernistas, como a narrativa não linear e o fluxo de consciência. A análise também faz uma reflexão sobre a representação da realidade na obra de Pessoa.The purpose of this essay is analyzing genre in Fernando Pessoa’s The Book of Disquiet (Vicente Guedes/Fernando Pessoa/Bernardo Soares), bringing this work closer to the novel literary genre. To this end we seek to show the way Pessoa creates a complex character, the protagonist narrator, and structures his fiction with the experimental techniques introduced in literature by the modernist writers such as non linear narrative and the stream of consciousness. The analysis also reflects on the representation of reality in Pessoa's work

Lumbar Malignant Peripheral Nerve Sheath Tumor in a Young Dog

Background: The most common location of malignant tumors of the peripheral nerve sheath in the spinal cord is the intradural-extramedullary region, and is rare in the spinal nerve roots in the lumbar region. They mainly affect large female dogs over six years of age. Imaging tests assist in the presumptive diagnosis, but confirmation requires histopathological and immunohistochemical examination. The prognosis is guarded. Diagnostic imaging, anatomopathological and immunohistochemical findings of a malignant tumor of the intradural-extramedullary peripheral nerve sheath with medullary infiltration in the lumbar region in a young dog are reported.Case: A body of a 6-year-old Poodle dog was donated for necropsy and diagnostic clarification. In the history, there was a suspicion of lumbar intramedullary neoplasia, detected by computed tomography (CT), with a 4 years progressive chronic evolution. Additionally, the dog had hidden spina bifida (L7 to S3), as detected by radiography and CT. On post mortem radiographic examination (X-ray), there was an enlargement of the vertebral canal (T10 to S2), intense osteolysis (L1 to S2), spinous processes (L5 to L7), and ankylosis (L3 to L7). Necropsy revealed ankylosis (L3 to L7) and intradural-extramedullary mass (9.5 × 2.6 × 2.3 cm) (L2 to L6). No metastases were identified. On microscopy, there was neoplastic proliferation of cells with intense pleomorphism, arranged in bundles interlaced in palisades and sometimes solid mantles. The mitotic index was high, ranging from 10 to 12 mitoses per field. There was also necrosis, hemorrhage, edema, and focal axonal demyelination of the adjacent white matter in the spinal cord. Masson Trichrome staining highlighted an intense diffuse conjunctive stroma. There was a suspicion of a malignant tumor of the peripheral nerve sheath and an immunohistochemical panel was performed for confirmation. There was strong and diffuse positivity for vimentin and S-100 and partial positivity for neuron-specific enolase (NSE), negative for anti-factor VIII, glial fibrillary acidic protein (GFAP), α-actin for smooth muscle, cytokeratin, neurofilament, and desmin. Thus, the diagnosis of malignant neoplasm of the peripheral nerve sheath was confirmed.Discussion: Peripheral nerve sheath tumors are classified as benign or malignant. In dogs, they are frequent in elderly, females, and large breeds. In this case report, the animal was young, female, and small breed. The location of the spinal nerve roots is uncommon, and is more commonly found in the brachial plexus. In the animal reported, the tumor was observed as lumbar swelling. Clinical signs vary with the affected region, however, neurogenic claudication and muscle atrophy are more frequent, as observed in this report. Imaging examinations such as X-rays and CT assist in the presumptive diagnosis. In this case report, spina bifida was identified on radiography, and CT suggested the presence of intramedullary neoplasia and allowed to monitor tumor growth. Post mortem X-ray imaging revealed intense osteolysis and ankylosis, which were confirmed at necropsy, which also elucidated its intradural-extramedullary location with infiltration into the spinal cord. The confirmation of the neoplasm was made by histopathological and immunohistochemical examination; the latter should be made a panel, not restricted to the use of antibodies S-100 and vimentin only. The prognosis of malignant peripheral nerve sheath tumors (MPNST) of the spinal cord is poor, and although there are palliative methods, there is no curative treatment, as complications can interfere with the quality of life of the animal. MPNST should be included in the differential diagnosis of spinal disorders, even in young dogs and small breeds. CT helps in early diagnosis to make decisions aimed at the animal's well-being

Meningocele and Meningoencephalocele in Piglets: Pathologic and Imaging Aspects

Background: Meningocele and meningoencephalocele are rare congenital deformities characterized by herniation of the meninges and of the meninges and brain tissue through a bone defect in the skull (cranioschisis), respectively. Descriptions of these malformations in pigs are scarce in the international literature and non-existent in Brazil, with only one case of cranioschisis with brain exposure (without protrusion of the meninges and covered by skin) reported to date. Here, we report a case of meningocele and another of meningoencephalocele in piglets in the state of Bahia and describe the main related anatomopathological and imaging characteristics (radiographic and ultrasonographic).Case: The congenital malformations occurred in newborn piglets from a farm located in the city of Catu, Bahia, Brazil, which presented with an evident large saccular area positioned dorsally to the head. The animals died 48 h after birth and were referred to the Laboratory of Animal Pathology of the Federal University of Bahia, for the studies and diagnostic conclusion. Postmortem ultrasound examinations showed that the region was filled with fluid and associated with a small brain protrusion in case 1 and a defect in the skull bone, which had its orifice dimensions estimated. Despite the superimposition of structures, the skull malformation was identified on radiographic examination (case 1) and measured on ultrasonographic examination (cases 1 and 2). During necropsy, the piglets presented with a marked marked bulge of saccular appearance under the skin in the frontal region. The saccular formation was floating, internally covered by dura mater and filled with reddish serous liquid (liquor).Discussion: The diagnoses of meningoencephalocele and meningocele in newborn piglets were established based on morphological changes identified on ultrasound and necropsy. Although the ultrasound diagnosis of meningocele and meningoencephalocele are routinely made in human medicine, they are still limited in veterinary medicine in cases of malformations in production animals, with no case report in pigs. A Brazilian textbook on pig diseases cites these diseases among the main malformations that affect this species, although data on epidemiology and anatomopathological and imaging findings are not described, which highlights the importance of this study. As for the etiology of these malformations, the occurrence of two cases in piglets from the same farm in the present report may suggest the presence of genetic factors. The confirmation that inbreeding is common at farms where the cases occurred, and absence of herd renewal since 2014 (continuous use of the same breeders), reinforced this hypothesis, since inbreeding results in serious reproductive and productive disorders due to increased homozygosis and, consequently, due to the frequency of genotypes with recessive genes that cause various malformations in animals. This fact reinforces the need to make producers aware of the importance of avoiding inbreeding and the use of breeders that have generated malformed piglets to reduce the frequency of malformations. Additional studies on congenital malformations in pigs in Brazil are necessary because of the scarcity of existing data, particularly regarding the etiology and anatomopathological and imaging characteristics of these diseases
