Loneliness is an epidemic affecting mental health across all demographics. It is linked to mental disorders, such as anxiety and depression, and despair, highlighting a significant public health issue as persons feel more disconnected in a connected world. This study aims to investigate the relationship between loneliness, Alzheimer's disease and suicidal behaviour. This review was systematised in a dichotomous manner. Therefore, two systematic reviews were initially carried out following the PRISMA statement. The loneliness was understood as feeling lonely. One group searched for associations between loneliness and Alzheimer's disease and the other between loneliness and suicidal behaviour, with a consecutive meta‐analysis. After that, it was searched for between the two groups to seek loneliness, such as an interface in meta‐analytic factor analysis. Depression is the most studied and cited factor associated with loneliness as a link between Alzheimer's disease and suicide. Loneliness demonstrated association with Alzheimer's disease (OR = 1.89, 95% CI 1.57–2.28; p < 0.001); suicidal ideation (OR = 2.17, 95% CI 1.88–2.51; p < 0.001); suicidal planning (OR = 2.36, 95% CI 1.91–2.92; p < 0.001); suicide attempt (OR = 2.54, 95% CI 2.13–3.04; p < 0.001); and suicide (OR = 4.9, 95% CI 4.4–5.5; p < 0.001). Entrapment, hopelessness, insomnia and stress demonstrated significative correlation ( r > 0.40; p < 0.001) with loneliness in the interface between AD and suicidal behaviour. Loneliness has been identified as a comorbid factor between AD and suicide. To prevent both AD and suicide, it is essential to monitor levels of stress, insomnia, feelings of entrapment and hopelessness. The triad of loneliness, hopelessness and insomnia seems to represent the greatest risk profile.

Background: Aneurysmal subarachnoid hemorrhage (ASAH) and unruptured aneurysm (URA) are particularly important because of the high mortality rates, and physical and cognitive impairment, which affect the economically active population. The present work aims at describing the scenario regarding in-hospital indicators related to the following therapeutic approaches: vascular microsurgery (VMS) and endovascular therapy (EVT) in the state of Minas Gerais, Brazil, in order to gather information to construct hypotheses and plan actions. Methods: The study has an ecological design and it is also analytical for the time trends of 2008-2014. Trends for VMS and EVT therapies and mortality are estimated using linear regression, followed by the Prais-Winsten procedure. Data were obtained through Hospital Information System (Sistema de Informações Hospitalares - SIH) of Brazilian Public Health System (Sistema Único de Saúde - SUS). Results: In 2014, 601 procedures were performed, and out of these, 373 (62%) were triggered by SAH and 228 (38%) by URA. The frequency of procedures performed in males and in females results in a ratio of 1:2 for SAH procedures and 1:3 for URA procedures. A heterogeneous distribution of therapeutic approaches was seen among the hospital studied, suggesting a technological preference, which determines the therapeutic approach. Conclusion: Technological bias was observed for aneurysm treatment in Minas Gerais’s hospitals. EVT is seen to have a growing trend to detriment of VMS (β₁=0.024; p=0.025), with a stable mortality for both therapeutics in both pathologies (SAH and URA). EVT has been associated with a shorter hospital stay, with higher expenses for both ASAH and URA treatment. EVT showed an inverse correlation with in-hospital fatality for ASAH treatment.

Introduction: Glycogen synthase kinase 3 (GSK-3) has been associated with a lot of diseases, such as Alzheimer’s Disease and diabetes. Its role in depression is connected to stress and neuroinflammation. Lithium is an essential inhibitor of GSK-3. Some studies have suggested that the use of this psychiatric medication may lower suicide rates. Here, we outline the current understanding and discoveries regarding the link between GSK-3 and suicide. Method: We used the PRISMA statement and defined the PECOS strategy, such as Population (P) = individuals; exposure (E) = GSK-3 alteration function; comparison (C) = without GSK-3 alteration function; outcome (O) = suicide; and study design(S) = all kinds of studies with an association between GSK-3 and suicide. Results: Twelve studies were included in this review. GSK-3 appears to be related to suicidal behavior by activating inflammatory pathways, activating genes, altering neurotransmission, and increasing impulsivity. Clinical studies do not present robust results that allow defining an epidemiological profile of greater risk for suicidal behavior in association with changes in the functioning of GSK-3. Conclusion: The interference of GSK-3 functioning in suicidal behavior seems inevitable, with solid evidence from laboratory animal studies. However, there is a need for further clinical studies on this crucial topic to answer better some questions about the association between GSK-3 and suicide.

Background: Suicidal behavior has been a dilemma in Alzheimer's disease. Many ethical debates have been raised about euthanasia in patients with neurodegenerative diseases, and there is a finding of increased suicide rates in the early stages of dementia. However, little is known about the history of suicide ideations or attempts in people with Alzheimer's disease. We aim to measure questionnaire adequacy and acceptability in this specific study to investigate the history of behaviors and factors associated with suicidal behavior across the lifespan in patients with Alzheimer's disease. Methods: This study is an excerpt from case-control research, where the sample was calculated at 150 participants, 75 for the case group and 75 for the control group. Here, the descriptive statistics of the first third of the case group sample, 25 participants, were made. Adequacy was observed by comprehension of questionnaires, and acceptability was measured by participants' understanding of the study object.Results: The prevalence of suicidal ideation throughout life was 8%, and 4% attempted suicide at some point in their lives. The total score of QLoS had a median of 71, which demonstrated the consideration of a moderate quality of life. The total score of the SAF-quest had a median of 12, which showed a low suicidal behavior history. All patients were included in understanding the questionnaires.Conclusions: This study demonstrated the adequacy, acceptability, and scarcity of suicidality histories throughout life in Alzheimer’s disease patients.

This clinical case examines central retinal serous chorioretinopathy in a patient undergoing treatment with semaglutide. The subject of the case is a middle-aged male who developed this retinal condition following the administration of 14 mg of oral semaglutide. He reported a variety of vision-related disturbances that significantly impacted his daily activities. Fortunately, the visual impairments were completely resolved upon discontinuation of the medication. This case underscores the critical importance of vigilant ophthalmological monitoring for patients receiving semaglutide. It is imperative to monitor for any potential adverse effects on vision, thereby facilitating the prompt recognition and management of any changes or complications. By prioritizing regular eye examinations, healthcare providers can protect patients' visual health and promptly address any issues that may arise during their treatment.

Background: There have been reports of numerous risk factors for Alzheimer's disease. Although widely investigated, some points during the evolution of the disease have been obscure. One of them is a great frustration with therapeutic expectations. Why has there been an increase in suicidal behavior in treatments with anti-beta-amyloid drugs? Interpersonal stress is one of the factors that may be connecting Alzheimer's disease to suicide. Method: To observe possible associations between Alzheimer's disease and suicide, two validated questionnaires were selected. We recruited 20 elderly patients over 65 years old to observe the feasibility of further research using these instruments. The study was considered viable if all participants showed no difficulty in understanding the questions and completed both questionnaires in less than 30 minutes with a tendency to homogeneity. A description of the statistical data obtained was made. Results: All participants adequately understood the questions and completed the questionnaires in less than 30 minutes. In 10% of the sample, suicide attempts occurred throughout their lives. The average age of respondents was 75 years old. The QoSL Pareto diagram demonstrated a large concentration. The data demonstrated homogeneity. Conclusions: The application of the questionnaires in a sample suitable for carrying out analytical statistics was demonstrated. We have two great tools to try to understand the possible association between Alzheimer's disease and suicide.
