Abstract
T cells are critical in mediating the early control of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) breakthrough infection. However, it remains unknown whether memory T cells can effectively cross-recognize new SARS-CoV-2 variants with a broad array of mutations, such as the emergent hypermutated BA.2.86 variant. Here, we report in two separate cohorts, including healthy controls and individuals with chronic lymphocytic leukemia, that SARS-CoV-2 spike-specific CD4+ and CD8+ T cells induced by prior infection or vaccination demonstrate resilient immune recognition of BA.2.86. In both cohorts, we found largely preserved SARS-CoV-2 spike-specific CD4+ and CD8+ T cell magnitudes against mutated spike epitopes of BA.2.86. Functional analysis confirmed that both cytokine expression and proliferative capacity of SARS-CoV-2 spike-specific T cells to BA.2.86-mutated spike epitopes are similarly sustained. In summary, our findings indicate that memory CD4+ and CD8+ T cells continue to provide cell-mediated immune recognition to highly mutated emerging variants such as BA.2.86.

Abstract
Introduction The SARS-CoV-2 pandemic is affecting numerous dimensions of our society since the beginning of the outbreak. A significant increase in emotional distress was expected in the general population, particularly among the high-risk groups such as the oldest, chronic patients, healthcare professionals, and psychopathology vulnerable people. There was an urgent need to adapt and create solutions to promote mental health. Given the recommendations to minimize face-to-face interactions, several helplines were widely developed. Objectives In this work, we aim to reflect on the experience of a university helpline, that integrated efforts with the regional mental health care services. Methods
A University helpline was created to give support to the regional community outside academia. The team was created on an online teamwork platform, to communicate through the chat, carry videoconference meetings, and store useful files. A Manchester screening decision tree was adopted, to define a set of guidelines to provide support to the callers, based mainly on the guidelines defined by the Order of Portuguese Psychologists. Liaison with the mental health care services, including other specific helplines, was established. Results Notwithstanding all the efforts, the number of received calls was scarce, similarly to helplines created by other national universities and by other entities. Conclusions A new approach to psychological intervention in crisis is needed, maintaining integrated efforts, and taking advantage of the opportunity to foster personalized mental health care in the digital era. It is important to continuously assess the value of integrated efforts in patient care and to the healthcare system.

Abstract
Antibiotic therapy (AT) is the cornerstone of the management of severe community-acquired pneumonia (CAP). However, the best treatment strategy is far from being established. To evaluate the impact of different aspects of AT on the outcome of critically ill patients with CAP, we performed a post hoc analysis of all CAP patients enrolled in a prospective, observational, multicentre study. Of the 502 patients included, 76% received combination therapy, mainly a β-lactam with a macrolide (80%). AT was inappropriate in 16% of all microbiologically documented CAP (n=177). Hospital and 6months mortality were 34% and 35%. In adjusted multivariate logistic regression analysis, combination AT with a macrolide was independently associated with a reduction in hospital (OR 0.17, 95%CI 0.06-0.51) and 6months (OR 0.21, 95%CI 0.07-0.57) mortality. Prolonged AT (>7days) was associated with a longer ICU (14 vs. 7days; p<0.001) and hospital length of stay (LOS) (25 vs. 17days; p<0.001). Combination AT with a macrolide may be the most suitable AT strategy to improve both short and long term outcome of severe CAP patients. AT >7days had no survival benefit and was associated with a longer LOS.

Abstract
A prospective, cohort, clinical, observational study was performed in 14 Intensive Care Units (ICUs) to evaluate the contemporary epidemiology, morbi-mortality and determinants of outcome of the population with an infection on admission. All 3766 patients admitted during a consecutive 12-month period were screened. Their median age was 63 [26-83], 61.1% were male and 69.8% had significant comorbidities. On admission to the ICU 1652 patients (43.9%) had an infection, which was community acquired in 68.2% (one-fifth with healthcare-associated criteria) and ward-acquired in the others. Roughly half presented to the ICU with septic shock. As much as 488 patients with community-acquired infections were deemed stable enough to be first admitted to the ward, but had similar mortality to unstable patients directly admitted to the ICU (35.9% vs. 35.1%, p 0.78). Only 48.3% of this infected population had microbiological documentation and almost one-quarter received inappropriate initial antibiotic therapy. This, along with comorbidities, was a main determinant of mortality. Overall, infected patients on admission had higher mortality both in the ICU (28.0% vs. 19.9%, p <0.001) and in the hospital (38.2% vs. 27.5%, p <0.001) and even after being discharged to the ward (14.2% vs. 9.6%, p <0.001). Also, patients not infected on admission who acquired an infection in the ICU, had an increased risk of dying in the hospital (odds ratio 1.41 [1.12-1.83]). Consequently, infection, regardless of its place of acquisition, was associated with increased mortality. Improving the process of care, especially first-line antibiotic appropriateness, and preventing ICU-acquired infections, may lead to better outcomes.

Abstract
PURPOSE Rhabdomyolysis is a syndrome caused by musculoskeletal tissue damage that leads to the release of large amounts of intracellular elements, which particularly affect renal function. The most common causes are severe trauma, ischemia, surgical procedures, and drug abuse. We aimed to determine the incidence of rhabdomyolysis by measuring muscle injury markers (CK, myoglobin), to identify pre/post-admission as well as iatrogenic risk factors for rhabdomyolysis in severe polytrauma, to clarify the relevance of orthopedic injuries and surgical treatment in the onset/worsening of rhabdomyolysis, and to correlate risk factors with its main complication-acute renal failure (ARF). METHODS Prospective study of severe polytrauma patients (Injury Severity Score (ISS) >15), with CK and myoglobin values measured at admission and after 24, 48, and 72 h. Peak values, variations between admission and peak, and variations between admission and day 3 were all determined. The correlations of those values with the onset of ARF and other negative outcomes were assessed. RESULTS A total of 57 consecutive patients with a median ISS of 29 were included. ARF was present in 20 patients (38 %). CK-0 level was correlated with male gender (p < 0.027) and ISS (0.014); Mb-0 level was correlated with hypovolemic shock (0.003) and skeletal fracture (p < 0.043). CK-max was correlated with surgery (p < 0.038) and surgery duration (p < 0.014); Mb-max was correlated with surgery (p < 0.002) and anesthesia duration (p < 0.005). Δ-CK was correlated with surgery (p < 0.01) and surgery duration (p < 0.017), and Δ0-3-CK was correlated with surgery (p < 0.042). Logistic regression analysis found relationships between Δ0-3-CK and both ICU admission (p < 0.003) and MODS (p < 0.012), and between Mb-max and ARF (p < 0.034). CONCLUSION We found that a large number of factors are implicated in CK and Mb variations. Rhabdomyolysis is a very frequent complication, but increase in CK marker alone does not seem to be correlated with the incidence of ARF. Therefore, Mb level should be considered in this group of patients.

Abstract
Background:Diogenes syndrome is the combination of severe self-neglect, domestic squalor, social withdrawal, a tendency to hoard excessively, and refusal of help, in elderly patients.Aim:To report a case of Diogenes’ syndrome underlying the impact of pathological hoarding behaviour in the quality of life of the patient. to discuss the pathological hoarding behaviour (syllogomania) in the context of this specific behavioural disorder.Methods:Case study and review of the literature.Results:The subject of this case study is a 78-year-old man with Diogenes syndrome. Hoarding behaviour is the major presentation symptom in this case, along with domestic squalor and social withdrawal. He has marked obsessive personality traits, no insight for his morbid condition and an attitude of refusal of treatment.Discussion:The literature reveals high comorbidity of Diogenes syndrome with psychiatric and somatic disorders. Some authors raise the possibility that obsessive-compulsive disorder may be the cause of hoarding rubbish in those cases of Diogenes syndrome in which hoarding exists and cannot be better explained by other psychopathology. other authors hypothesise Diogenes syndrome as a reaction to stress in elderly people with certain personality characteristics or as the end stage of a personality disorder. the ethiopathogeny of Diogenes syndrome remains unclear and there is no consensus about diagnostic criteria. It is a relevant area for future research, contributing for a better comprehension of the differential diagnosis of pathological hoarding behaviour and late life psychopathology.

Abstract
Anti-BP-7,8-diol 9,10-oxide (r-7,t-8-dihydroxy-t-9, 10-oxy-7,8,9,10-tetrahydrobenzo[a]pyrene) was converted in the presence of a rat-liver supernatant fraction and glutathione into a water-soluble metabolite that was identified as a glutathione conjugate. The formation of the glutathione conjugate appears to be catalysed by glutathione S-transferases, present in the rat-liver supernatant, because the amount of conjugate formed was reduced considerably when anti-BP-7,8-diol 9,10-oxide was incubated with glutathione either in the absence of the supernatant fraction or in the presence of heat-denatured supernatant fraction.

Abstract
Benz[a]anthracene-10,11-diol, a major metabolite of benz[a]anthracene, is metabolized by a rat-liver microsomal system to form anti-BA-10,11-diol 8, 9-oxide (t-10,r-11-dihydroxy-t-8,9-oxy-8,9,10,11 -tetrahydrobenz[a]anthracene) and, to a lesser extent, syn-BA-10,11-diol 8,9-oxide (t-10,r-11-dihydroxy-c-8,9-oxy-8,9,10,11-tetrahydrobenz[a] anthracene). However, when benz[a]anthracene is incubated with DNA in a rat-liver microsomal system, anti-BA-10,11-diol 8,9-oxide does not contribute to the covalent binding of this hydrocarbon to DNA.
