Background: Hypermagnesemia predicts mortality in chronic heart failure (HF); however, in acute HF, magnesium does not seem to be outcome-associated. Diabetes mellitus (DM) frequently associates with altered magnesium status. We hypothesized that DM might influence the prognostic impact of magnesium in acute HF.

Methods: This is a retrospective cohort study of hospitalized patients with acute HF. Patients without data on admission serum magnesium were excluded. Follow-up: 1 year from hospital admission. Primary end point: all-cause mortality. Patients were divided according to median serum magnesium (1.64 mEq/L). The Kaplan-Meier survival method was used to determine survival curves according to magnesium levels. The analysis was stratified according to the presence of DM. A multivariable Cox regression analysis was used to study the prognostic impact of magnesium.

Results: We studied 606 patients. The mean age was 76 ± 12 years, 44.1% were male, 50.7% had DM, and 232 (38.3%) died during follow-up. Median magnesium was 1.64 (1.48-1.79) mEq/L. Patients with magnesium ≥1.64 mEq/L had higher 1-year mortality [141 (46.4%) vs 91 (30.1%), P < .001]. After adjustments for age, sex, history of atrial fibrillation, systolic blood pressure, heart rate, ischemic etiology, B-type natriuretic peptide, estimated glomerular filtration rate, alcohol consumption, antihyperglycaemic agents or glycated hemoglobin, admission glycemia, New York Heart Association class IV, and severe left ventricle systolic dysfunction, serum magnesium ≥1.64 mEq/L was associated with higher mortality only in patients with DM: HR 1.89 (95% confidence interval: 1.19-3.00), P = .007, and 1.27 (95% confidence interval: 0.83-1.94) and P = .26 for non-DM patients. The results were similar if magnesium was analyzed as a continuous variable. Per 0.1 mEq/L increase in magnesium levels, patients with DM had 13% increased risk of 1-year mortality.

Conclusions: Higher magnesium levels were associated with worse prognosis only in HF patients with DM.

Background: Delirium is a very common neuropsychiatric disorder in the elderly, with a significant physical and psychological burden. Much is still unknown about its psychological effects. This study aims to identify the proportion of patients who recall delirium and to analyze the distress caused by it. In addition, this study aims to analyze the association between delirium recall and related distress and global psychological distress regarding hospitalization. Methods: This is a prospective study with elderly hospitalized patients in level-2 units of intensive care medicine department of a university hospital. Exclusion criteria were a Glasgow Coma Scale total ≤11, brain injury, blindness, deafness, or inability to communicate. Delirium was daily assessed with the Confusion Assessment Method. Delirium recall and related distress in patients were measured using the Delirium Experience Questionnaire. Global psychological distress was assessed with the Kessler Psychological Distress Scale. Results: From 105 patients, 38 (36.2%) developed delirium. Most patients did not remember the delirium episode (64.7%). Among those who remembered (35.3%), most described delirium as a distressing experience (75%). Delirium recall was associated with high global psychological distress (P = .029). Conclusions: Distress related to delirium is high, namely in patients who recall the episode. Global psychological distress during hospitalization is associated with delirium recall. This study highlights the need to assess the experience of delirium in these patients, as well as the importance of providing support and psychological interventions to minimize the associated distress.

Background: Perioperative chemotherapy (PeriCh) is the current standard of care for stage II/III gastric cancer tumors in Europe. However, when it concerns patients who endure complications during PeriCh it is unclear if it increases the risk of postoperative complications and other poorer surgical outcomes. We aim to demonstrate if there is an association between having complications during PeriCh and postoperative complications and histopathological response.

Methods: We conducted a retrospective, transversal, and observational study, including all patients with diagnosed gastric cancer who underwent PeriCh followed by surgical resection during the period of eight years.

Results: We included 80 patients with a median age of 64.0years (min 24, max 78). Eighty-eight-point eight percent ended the chemotherapy regime proposed, with a median duration of 42 days, and were also submitted to gastric resection: 58.8% total gastrectomy and 41.2% distal gastrectomy. Twelve-point five percent of the patients had no complications during the PeriCh period and 16.3% had >2 complications. Twenty-five percent of patients had a histological response of <10% of tumor burden, but in 41.3% only regression of <50% could be obtained. No significant association was found between complications during PeriCh and adverse surgical outcomes (P = .497). Patients with complications during PeriCh had slightly higher median time difference from end of PeriCh until surgery, but with no statistical significance (P = .575).

Conclusions: In our sample, the existence of association between complications during PeriCh and postoperative complications or histological response was not demonstrated.

Background: The concept of autonomy is composed of several components, making it a multidimensional concept. This includes cognitive ability, intellectual ability, emotional intelligence, social situation, and physical ability skills. This study aimed to describe the experiences attributed to the meaning of the concept of autonomy, by specialist nurses. Methods: A descriptive phenomenological study was carried out, according to the Giorgi method. Eighteen nurses were recruited at a hospital in Portugal. Data were collected through individual interviews. Results: The 18 specialist nurses work on average as nurses for 16years and are specialist nurses; for an average of 5.9years, most are specialist nurses in rehabilitation nursing. From the data analysis, six themes emerged: ability to do, ability to resolve, decision ability, cognitive ability, social integration, and emotional intelligence. Conclusions: Most professionals perceive the concept as the ability to perform activities of daily living and the ability to make decisions, especially concerning informed consent. It is necessary to raise awareness of the breadth of this concept since the quality of life and dignity of the elderly person depends on autonomy.

Transurethral resection of newly diagnosed bladder tumors (TURBT) is a hallmark ¡n the treatment of bladder cancer. We evaluated the surgeon capacity to predict bladder tumor stage (T), grade, and presence of muscular layer based upon cystoscopic characteristics during primary TURBT.

Methods: Prospective study enrolling 100 consecutive patients undergoing primary TURBT for newly diagnosed bladder cancers. Cystoscop¡c tumor characteristics at the time of TURBT was evaluated by an urology senior and a resident regarding histological grade, invasion (T stage), and presence of muscular layer in the specimen. We analyzed the surgeon's accuracy in predicting these parameters using the final histology as gold standard. In addition, the predictive capacity between seniors and residents was compared.

Results: The resident's arm correctly predicted tumor invasiveness in 76% of cases, while seniors correctly predicted 87% of cases. Regarding tumor grade, high grade cancer was reported in 78% of the specimens and 75% and 77% of them were correctly predicted by residents and seniors, respectively. Finally, 80% of the TURBT specimens had muscle representativeness. In nearly 75% of the cases, both resident and senior correctly predicted the TURBT resection depth (presence of detrusor muscle in the specimen). The positive predictive value for this parameter was 79% for the resident, and 81% for the senior, and the negative predictive value was 25% and 40%, respectively.

Conclusion: The surgeon's naked eye analysis showed a good, but limited predictive ability to detect non-muscle invasive and high-grade bladder tumors in TURBT specimens. Positive predictive value for muscle representativeness is around 80%, which reinforces the need of carrying out a careful and extensive TURBT, irrespective of the surgeon experience.

Anxiety is one of the most frequent psychiatric disorders in heart failure (HF) patients. However, it is often neglected in clinical practice and studies about the particular relationship with the New York Heart Association (NYHA) classes for HF are scarce. In this context, this study aims to analyze the presence of anxiety symptoms in HF outpatients and also its association with sociodemographic and clinical characteristics of these patients.

Methods: This cross-sectional study is part of the longitudinal Deus Ex-Machina project (NORTE-01-0145-FEDER-000026). HF patients were recruited at an outpatient clinic at a University Hospital. Patients with inability to communicate, severe visual/hearing impairment, or NYHA class IV were excluded. Sociodemographic data and NYHA class were registered. Anxiety was assessed with the 7-item Generalized Anxiety Disorders Scale (with a score ≥10 clinically relevant anxiety). Patients with and without anxiety were compared regarding socio-demographic and clinical variables.

Results: The sample (n = 136) had a median age of 59years (Q₁: 49; Q₃: 68), 66.2% were male and 31.6% presented clinically relevant anxiety. A higher percentage of HF patients with anxiety had psychiatric disorders (58.1% vs 26.9%; P = .001), psychotropic medication (62.8% vs 30.1%; P = .001), and depression (60.5% vs 9.7%; P< .001). No significant differences were found regarding the remaining variables, including NYHA classes.

Conclusions: A substantial proportion of HF patients present clinically relevant anxiety, particularly those with psychiatric history, depressive symptoms, or under psychotropic medication. Therefore, integrating routine screening and treatment of this comorbidity in clinical practice is of utmost importance. Further studies are needed to clarify the association of anxiety with HF.

Autonomy is one of the essential components to live a quality life. Monitoring this autonomy is, in effect, essential, to allow the nurses to conceive, implement and evaluate interventions aimed at its promotion or even maintenance. For this reason, this scoping review aims to map the evidence to identify and analyze the instruments used to assess the person's autonomy, which emerges from scientific production.

Methods: Scoping review based on the recommended principles by the Joanna Briggs Institute. The research was realized in the databases: Scopus (excluding MEDLINE), CINAHL complete (via EBSCO, Excluding MEDLINE), and MEDLINE (via PubMed). Two independent reviewers evaluated the articles' pertinence for the study's investigation, the extraction, and synthesis of articles.

Results: After the analysis, according to the inclusion criteria established, 34 articles were selected, allude to 7 different instruments to assess autonomy.

Conclusions: The need for further development at this level is highlighted, namely through the construction and validation of more comprehensive instruments, integrating the different components of the concept of autonomy.

We report an unusual case of cerebral venous thrombosis (CVT temporally associated with an otherwise asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. While coronavirus disease 2019 (COVID-19) has been associated with thrombotic events at different sites, most published cases report on symptomatic SARS-CoV-2 infection. We are confident this was an otherwise asymptomatic infection as the patient reported no symptoms and molecular and serological testing was consistent with infection more than 3weeks in the past. We believe this is an important report as it adds to the existing literature on thrombotic events in patients with COVID. It may even inform discussion of COVID vaccines and CVT since our patient, as those reported in association with vaccines, also had thrombocytopenia on admission.
