The Use of Methylene Blue in Conjunction With Hydroxocobalamin and Multiple Pressors to Treat Severe Vasoplegia in a Patient Due to Calcium Channel Blocker Toxicity: A Case Report.
Vasoplegia, the demonstration of persistently low systemic vascular resistance (SVR) and resistant hypotension in the presence of a normal cardiac index despite aggressive resuscitation attempts, is a serious clinical diagnosis that requires prompt treatment to prevent patient morbidity and mortality. Currently, treatment of vasoplegia involves treatment with vasopressors such as vasopressin, norepinephrine, and hydroxocobalamin. However, some evidence suggests that in addition to this treatment regimen, the addition of methylene blue may result in a reduction in overall norepinephrine equivalent vasopressor requirements, increased mean arterial pressure, and an improved clinical course. Here, we report the case of a 64-year-old male patient who presented to the ED after being found unresponsive and covered in emesis at home. The patient's presentation was complicated by worsening dyspnea, hypotension, and hemodynamic instability, requiring intubation and admission to the ICU for management of undifferentiated shock of unclear etiology and acute respiratory failure. Urine studies were consistent with a diagnosis of vasoplegia due to dihydropyridine calcium channel blocker toxicity, which was confirmed by pill counting of his home medications in the setting of recent paranoia and depression. The patient was treated aggressively with vasopressors, including vasopressin, phenylephrine, and epinephrine, as well as a combination of hydroxocobalamin and methylene blue. He was also started on a calcium and insulin drip. Upon initiation of non-catecholamine agents for vasoplegia, his clinical course quickly improved, and he was weaned from all vasopressors. He regained hemodynamic stability, was successfully extubated, evaluated by psychiatry, and discharged from the hospital in a stable condition on day 15 with the continuation of outpatient psychiatric services.

Review
This comprehensive review explores the intricate relationship between security technologies and mental health. Security technologies, including physical security, cybersecurity, and surveillance measures, are integral components of our modern world, designed to protect individuals, organizations, and society from various threats. While they are vital in enhancing safety, they also have profound implications for mental well-being. The review delves into the positive impacts of security technologies, including their capacity to enhance personal safety, reduce anxiety and fear, and instill a sense of security. However, it also reveals the negative consequences, such as privacy invasion, surveillance-related stress, paranoia, and ethical concerns, which can erode mental health. User perception and trust are central to understanding how individuals experience security technologies. The review emphasizes the importance of ethical guidelines, user education, and technological advancements in mitigating negative impacts. By embracing an ethical-by-design approach, empowering users, and promoting public awareness, a balanced equilibrium between security and mental health can be achieved. The conclusion highlights the significance of ongoing research and interdisciplinary collaboration to navigate this intricate relationship effectively. By prioritizing ethical considerations and fostering a dialogue that values security and individual well-being, we can ensure a safer and more mentally healthy future in our technologically interconnected world.

Decreased sleep spindle activity in individuals with psychotic disorders is well studied, but its contribution to psychotic symptom formation is not well understood. This study explored potential underlying mechanisms explaining the association between decreased sleep spindle activity and psychotic symptoms. To this end, we analysed the links between sleep spindle activity and psychotic experiences and probed for the mediating roles of attentional performance and perceptual distortions in a community sample of young adults (N = 70; 26.33 ± 4.84 years). Polysomnography was recorded during a 90-min daytime nap and duration, amplitude, and density from slow (10-13 Hz) and fast (13-16 Hz) spindles were extracted. Attentional performance was assessed via a test battery and with an antisaccadic eye movement task. Psychotic experiences (i.e., paranoid thoughts; hallucinatory experiences) and perceptual distortions (i.e., anomalous perceptions; sensory gating deficits) were assessed via self-report questionnaires. We conducted sequential mediation analyses with spindle activity as predictor, psychotic experiences as dependent variable, and attentional performance and perceptual distortions as mediators. We found reduced right central spindle amplitude to be associated with paranoid thoughts. Increased antisaccadic error rate was associated with anomalous perceptions and perceptual distortions were associated with psychotic experiences. We did not find significant mediation effects. The findings support the notion that reduced sleep spindle activity is involved in the formation of paranoid thoughts and that decreased antisaccadic performance is indicative of perceptual distortions as potential precursors for psychotic experiences. However, further research is needed to corroborate the proposed mediation hypothesis.

Stiff-person syndrome (SPS) is an uncommon autoimmune neurological disorder marked by painful muscle stiffness, muscle spasms, and limb weakness. Neurological symptoms in SPS can mimic a psychogenic movement disorder in which symptoms are triggered by sudden movement and emotional distress, which might delay proper treatment. However, psychiatric symptoms are far less common, and there is limited understanding regarding the co-occurrence of psychiatric conditions. Psychiatric symptoms include nonspecific anxiety, agoraphobia, and depression, which can be triggered by sudden movement, noise, or emotional stress. This case report dives into the psychiatric manifestations seen in a patient with SPS. The case report focuses on a 42-year-old female with SPS, migraines, systemic lupus erythematosus, Sjogren's syndrome, and a psychiatric history of anorexia, depression, and anxiety. Her unique presentation underscored the necessity for a multidisciplinary approach to psychiatric care. The patient was evaluated and managed during her admission to the psychiatric unit for unspecified psychosis. Her course included a complicated medical evaluation for cardiovascular and neurologic symptoms and comprehensive psychiatric management. She manifested resistance to specific psychiatric medications and care strategies. She had atypical presentations, like sensory symptoms and left-sided chest pain. She exhibited paranoia and psychosis, which were managed with a combination of pharmacologic treatments, including aripiprazole. Psychotic symptoms were resolved upon discharge, with an emphasis on strict outpatient follow-up. This case report enhances our understanding of the clinical nuances associated with SPS and its intersection with psychiatric symptoms. The objective of this case report is to detail the diagnostic and therapeutic complexities of managing psychosis in a patient with SPS, along with a pre-existing complex medical and psychiatric profile, and to contribute to a deeper understanding of SPS and associated psychiatric conditions and more effective management strategies.

The lymphocyte-related ratios, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR) are new measures of inflammation within the body. Few studies have investigated the inflammatory response of patients with methamphetamine-induced psychotic disorder. Clinically, the psychotic symptoms and behavioural manifestation of methamphetamine-induced psychotic disorder are often indistinguishable from paranoid schizophrenia. We aimed to determine the differences in these inflammatory markers between patients with methamphetamine-induced psychotic disorder, patients with schizophrenia and healthy individuals. A total of 905 individuals were recruited. The NLR and MLR were found to be higher in both patients with methamphetamine-induced psychotic disorders and patients with schizophrenia compared with healthy controls. There was no significant difference between the three groups in PLR. When compared with the control group, the methamphetamine-induced psychotic disorder group was significantly higher in NLR 27% (95%CI = 11 to 46%, p = 0.001), MLR 16% (95%CI = 3% to 31%, p = 0.013) and PLR 16% (95%CI = 5% to 28%, p = 0.005). NLR of the group with methamphetamine-induced psychotic disorder was 17% (95%CI = 73% to 94%, p = 0.004) less than the group with schizophrenia, while MLR and PLR did not differ significantly between the two groups. This is the first study that investigated the lymphocyte-related ratios in methamphetamine-induced psychotic disorder when compared with patients with schizophrenia and healthy individuals. The results showed that both patients with methamphetamine-induced psychotic disorder and patients with schizophrenia had stronger inflammatory responses than the healthy control. Our finding also indicated that the inflammatory response of methamphetamine-induced psychotic disorder was between those of patients with schizophrenia and healthy individuals.

Posterior cortical atrophy (PCA) is a rare neurodegenerative disorder characterized by predominant visual deficits due to its atrophy of the occipital lobes. Patients typically have preserved cognitive function during the early stages, making diagnosis more difficult when compared to other neurocognitive disorders. In this case, the patient presented predominantly with mood symptoms, delusions, and visual hallucinations. The disease course began 5 years ago with anxiety and insomnia. It developed into depressive symptoms including two suicide attempts (SAs), paranoia, and hallucinations. The diagnosis was eventually reached utilizing a thorough clinical exam, neuropsychological testing, MRI, positron emission tomography (PET), and dopamine transporter (DAT) scans. We conclude that mood or psychotic symptoms that emerge, escalate, or change dramatically at later ages merit further workup to evaluate for underlying neurodegenerative disorders.
