Role of artificial intelligence in haemodynamic monitoring.

This narrative review explores the evolving role of artificial intelligence (AI) in haemodynamic monitoring, emphasising its potential to revolutionise patient care. The historical reliance on invasive procedures for haemodynamic assessments is contrasted with the emerging non-invasive AI-driven approaches that address limitations and risks associated with traditional methods. Developing the hypotension prediction index and introducing CircEWSTM and CircEWS-lite TM showcase AI's effectiveness in predicting and managing circulatory failure. The crucial aspects include the balance between AI and healthcare professionals, ethical considerations, and the need for regulatory frameworks. The use of AI in haemodynamic monitoring will keep growing with ongoing research, better technology, and teamwork. As we navigate these advancements, it is crucial to balance AI's power and healthcare professionals' essential role. Clinicians must continue to use their clinical acumen to ensure that patient outliers or system problems do not compromise the treatment of the condition and patient safety.

Enrichment of Immune Dysregulation Disorders in Adult Patients with Human Inborn Errors of Immunity.

Human inborn errors of immunity (IEI) comprise a group of diseases resulting from molecular variants that compromise innate and adaptive immunity. Clinical features of IEI patients are dominated by susceptibility to a spectrum of infectious diseases, as well as autoimmune, autoinflammatory, allergic, and malignant phenotypes that usually appear in childhood, which is when the diagnosis is typically made. However, some IEI patients are identified in adulthood due to symptomatic delay of the disease or other reasons that prevent the request for a molecular study. The application of next-generation sequencing (NGS) as a diagnostic technique has given rise to an ever-increasing identification of IEI-monogenic causes, thus improving the diagnostic yield and facilitating the possibility of personalized treatment. This work was a retrospective study of 173 adults with IEI suspicion that were sequenced between 2005 and 2023. Sanger, targeted gene-panel, and whole exome sequencing were used for molecular diagnosis. Disease-causing variants were identified in 44 of 173 (25.43%) patients. The clinical phenotype of these 44 patients was mostly related to infection susceptibility (63.64%). An enrichment of immune dysregulation diseases was found when cohorts with molecular diagnosis were compared to those without. Immune dysregulation disorders, group 4 from the International Union of Immunological Societies Expert Committee (IUIS), were the most prevalent among these adult patients. Immune dysregulation as a new item in the Jeffrey Model Foundation warning signs for adults significantly increases the sensitivity for the identification of patients with an IEI-producing molecular defect.

Incidence and warning signs for complications of human brucellosis: a multi-center observational study from China.

BACKGROUND: Brucellosis is a severe zoonotic disease that is often overlooked, particularly in impoverished countries. Timely identification of focal complications in brucellosis is crucial for improving treatment outcomes. However, there is currently a lack of established indicators or biomarkers for diagnosing these complications. Therefore, this study aimed to investigate potential warning signs of focal complications in human brucellosis, with the goal of providing practical parameters for clinicians to aid in the diagnosis and management of patients. METHODS: A multi-center cross-sectional study was conducted in China from December 2019 to August 2021. The study aimed to investigate the clinical characteristics and complications of patients with brucellosis using a questionnaire survey and medical record system. The presence of warning signs for complications was assessed using univariate and multivariate logistic regression models. Receiver operating characteristic (ROC) curves and the area under the curve (AUC) were used for variable screening and model evaluation. RESULTS: A total of 880 participants diagnosed with human brucellosis were enrolled. The median age of the patients was 50 years [interquartile range (IQR): 41.5-58.0], and 54.8% had complications. The most common organ system affected by complications was the osteoarticular system (43.1%), with peripheral arthritis (30.0%), spondylitis (16.6%), paravertebral abscess (5.0%), and sacroiliitis (2.7%) being the most prevalent. Complications in other organ systems included the genitourinary system (4.7%), respiratory system (4.7%), and hematologic system (4.6%). Several factors were found to be associated with focal brucellosis. These factors included a long delay in diagnosis [odds ratio (OR) = 3.963, 95% confidence interval (CI) 1.906-8.238 for > 90 days], the presence of underlying disease (OR = 1.675, 95% CI 1.176-2.384), arthralgia (OR = 3.197, 95% CI 1.986-5.148), eye bulging pain (OR = 3.482, 95% CI 1.349-8.988), C-reactive protein (CRP) > 10 mg/L (OR = 1.910, 95% CI 1.310-2.784) and erythrocyte sedimentation rate (ESR) elevation (OR = 1.663, 95% CI 1.145-2.415). The optimal cutoff value in ROC analysis was > 5.4 mg/L for CRP (sensitivity 73.4% and specificity 51.9%) and > 25 mm/h for ESR (sensitivity 47.9% and specificity 71.1%). CONCLUSIONS: More than 50% of patients with brucellosis experienced complications. Factors such as diagnostic delay, underlying disease, arthralgia, eye pain, and elevated levels of CRP and ESR were identified as significant markers for the development of complications. Therefore, patients presenting with these conditions should be closely monitored for potential complications, regardless of their culture results and standard tube agglutination test titers.

Evaluation of the Effectiveness of the 6 Warning Signs of the European Society for Immunodeficiencies for Primary Immunodeficiencies in Older Adults.

INTRODUCTION: Diagnostic delay in cases of primary immunodeficiency (PID) is a significant problem for clinicians, and most do not have sufficient awareness of this uncommon disorder. The European Society for Immunodeficiencies (ESID) has developed 6 warning signs to increase awareness of adult PIDs. The aim of this study was to determine the prevalence of PID in older adults regardless of the reason for presentation and to evaluate the effectiveness of the 6 warning signs of ESID in the diagnosis of PIDs. METHODS: The study included 1,331 patients aged ≥65 years who presented at our clinic for any reason and were questioned about the ESID 6 warning signs for PIDs. After the exclusion of reasons for secondary immunodeficiency (SID), all the patients underwent immunological evaluation for the diagnosis of potential underlying PIDs. RESULTS: After excluding 6 patients diagnosed with SID, PID was diagnosed in 16 (1.2%) of 1,325 older adults using ESID warning signs. The most common reasons for presentation were infection (69%) in the PID group and urticaria and/or angioedema (41.5%) in the non-PID group. The most common PID subgroup was common variable immunodeficiency (50%). In 12 of the patients diagnosed with PID, there was at least 1 positive ESID warning sign. In 4 patients, PID was determined despite negative ESID warning signs. The patients diagnosed with PID showed a significant, minimal level of agreement with questions 1 and 4 of the ESID warning signs (p < 0.001, ĸ = 0.204, p = 0.005, ĸ = 0.208, respectively). CONCLUSION: The ESID warning signs do not encompass all the symptoms and findings of PIDs. There is a need for more infection-centered questions to determine PIDs in older adults. Therefore, the ESID warning signs should be further developed.

Pathways of depressive symptoms to self-harm and suicide warning signs during COVID-19 pandemic: The role of anxiety and related distress, dysfunction and somatization.

BACKGROUND: Early in the COVID-19 pandemic, concern about widespread waves of depression and suicide emerged worldwide. Clarity on the relationship between mental health symptoms and warning signs of current self-harm or suicide thoughts and behaviors (ShSTB) in Mexican adults could be useful for designing effective public health policies and preventive strategies during health emergencies. OBJECTIVE: The present study uses a path model to explore the relationship between depressive symptoms, anxiety, and related distress, dysfunction, and somatization with ShSTB warning signs in Mexican adults during the COVID-19 pandemic. The study also describes the relative risks of these mental health variables for men and women, and for those who were seeking psychological care versus those who were not. METHOD: The study was conducted with 18,449 Mexicans (M = 33 years, SD = 11.00, range = 18-59), including 12,188 women (66.10 %) and 2706 (14.67 %) who were seeking psychological care. A web-based application included two multidimensional screening scales to evaluate depression, anxiety and somatic symptoms and related distress/dysfunction, as well as past and current ShSTB. Based on the participants' sex, the entire sample was randomly divided into two sub-samples to compare and replicate the Confirmatory Factor Analysis (CFA) results, getting evidence of the multidimensionality of the scales. With the two sub-samples, we also tested the nested models from a structural equation model (SEM) to suggest a relationship between mental health and self-harm/suicide variables. FINDINGS: Our findings suggest that 31 % of participants were at risk for depression, 42.30 % for anxiety, 38.30 % for Marked Distress, Dysfunction and Somatization (MDDS), 33.30 % for at least one ShSTB, and 4.20 % for Previous Self Harm Thoughts and Behaviors (PShTB) during the COVID-19 pandemic. A greater percentage of women and participants seeking psychological care showed high levels of mental health symptoms, PShTB, MDDS, and ShSTB. The path model suggested a direct influence of PShTB and MDDS on ShSTB. Depression symptoms lead to ShSTB in three possible ways: through PShTB, PShTB affecting MDDS, and generalized anxiety affecting MDDS. DISCUSSION AND OUTLOOK: The pandemic was accompanied by a high prevalence of depression-anxiety, marked distress, dysfunction and somatization and self-harm/suicide thoughts and behaviors. The findings of this study suggest evidence over the well-known association between depression and anxiety, and between depression, previous self-harm thoughts and behaviors, and self-harm/suicide. The evidence suggests to distinguish when participants were suffering from MDDS and anxious depression from those only suffering from depression. The methodological conditions of the study suggest a comprehensive model of ShSTB prevention. Findings also suggest the need to care for Mexicans with depressive symptoms and PShTB as well as those suffering from anxious depression with MDDS to prevent suicide, by implementing effective public health policies and preventive strategies to reduce the mental health gap during health emergencies. LIMITATIONS: This research was a cross-sectional study, suggesting that future analyses should focus on the evaluation of its consistency with confirmed diagnoses of mental health disorders, self-harm/suicide risks, and the effect of remote psychological help to address these problems.

Mapping morbidity 10 years prior to a diagnosis of young onset Alzheimer's disease.

INTRODUCTION: Early symptoms in young onset Alzheimer's disease (YOAD) may be misinterpreted, causing delayed diagnosis. This population-based study aimed to map morbidity prior to YOAD diagnosis. METHODS: In a register-based incidence density matched nested case-control study, we examined hospital-diagnosed morbidity for people diagnosed with YOAD in Danish memory clinics during 2016-2020 compared to controls in a 10-year period. Conditional logistic regression produced incidence rate ratios (IRRs). RESULTS: The study included 1745 cases and 5235 controls. YOAD patients had a higher morbidity burden in the year immediately before dementia diagnosis, for certain disorders up to 10 years before. This was especially evident for psychiatric morbidity with the highest increased IRRs throughout the entire period and IRR 1.43 (95% confidence interval 1.14-1.79) in the 5-10-years before dementia diagnosis. DISCUSSION: YOAD patients display a different pattern of morbidity up to 10 years prior to diagnosis. Awareness of specific alterations in morbidity may improve efforts toward a timely diagnosis. HIGHLIGHTS: Retrospective, nested case-control study of young onset Alzheimer's disease (YOAD). YOAD cases had a higher morbidity burden than controls. YOAD cases had a higher psychiatric morbidity burden up to 10 years before diagnosis. Altered morbidity patterns could serve as an early warning sign of YOAD.

Effectiveness of information technology assisted relapse prevention program on relapse among people who live with severe mental disorders.

BACKGROUND: Severe Mental Disorders (SMDs) cause mental health worldwide challenges because of several relapses and extensive recovery periods of hospitalization, which put a lot of economic and social burden on families and governments. Therefore, interventions are necessary to decrease the relapse of these disorders. AIM: This study was conducted to investigate the effect of Information Technology Assisted Relapse Prevention Program (ITAREP) on relapse among people who live with SMDs. METHOD: This study was a randomized clinical trial with intervention and control groups. ITAREP is a remote intervention based on monitoring the Early Warning Signs (EWS) to decrease the number of potential relapses. Using convenience sampling, people with SMDs admitted to Sina Juneqan Psychiatric Hospital and their caregivers were recruited in this study and randomly allocated to the control and intervention groups. Two checklists of the EWS for the patient and the patient's caregiver were used for monitoring the relapse signs. Data were collected at baseline and 90 days after discharge and were analyzed using t-test and Chi-square statistical tests and linear regression in SPSS software. RESULTS: Fifty-two patients who lived with SMDs participated in this study (26 in the intervention group and 26 in the control group). The two groups were homogeneous regarding age, gender, type of mental disorder, and duration of the disorder. Forty-two males and ten females participated in this research. Most of the participants were diagnosed with schizophrenia. The results showed that the number of relapses in the intervention group was significantly lower than in the control group in the post-test. CONCLUSION: Social workers, as the case managers and a member of the interdisciplinary psychiatric team, can actively perform follow-up measures after discharge using ITAREP, and it can be expected that these interventions will reduce the number of relapses among patients who live with SMDs.

Evaluation of Neurosurgical Emergencies in the Pediatric Emergency Department: Clinical Warning Signs.

BACKGROUND: We aimed to evaluate the patients who underwent neuroimaging with suspicion of neurosurgery pathology and identify the clinical warning signs for the early recognition of neurosurgical emergencies. METHODS: Patients aged one month to 18 years who underwent neuroimaging with a preliminary diagnosis of intracranial pathology requiring emergency surgery and symptom duration less than one month were included in the study. Patients were divided into three groups according to their definitive diagnosis as neurosurgical emergencies, neurological emergencies, and nonurgents. RESULTS: A total of 140 patients were included in the study (the median age was 8 [interquartile range IQR 3 to 13] years and 52.8% were male). Neurosurgery emergency group and neurological emergency group were significantly younger than the nonurgent group (P < 0.001). Vomiting, meningeal irritation findings, and papilledema (grade 2 and above) were more common in the neurosurgical emergency group (P 0.029, 0.023, and < 0.001, respectively). For neurosurgical emergencies, in the presence of papilledema (grade 2 and above) and focal neurological deficit, the specificity was 99.2%, positive predictive value (PPV) 83.3%, negative predictive value (NPV) 88.1%, and odds ratio (OR) 36.8 (P < 0.001, confidence interval [CI] 4.04 to 336.0); in the presence of altered consciousness and focal neurological deficit, the specificity was 97.5%, PPV 50%, NPV 86.6%, and OR 6.4 (P = 0.014, CI 1.20 to 34.4). CONCLUSIONS: Younger age, presence of vomiting, signs of meningeal irritation, papilledema grade 2 and above, and altered consciousness are the crucial "warning signs" of a potential neurosurgical emergency.

Cryptococcal Meningitis Presenting as Chronic Headache in an Apparently Immunocompetent Patient.

Cryptococcal meningitis, a severe fungal infection, usually afflicts immunocompromised individuals, mainly those with acquired immunodeficiency syndrome (AIDS). However, rarely, immunocompetent individuals can develop the infection too. Here, we present a case of a human immunodeficiency virus (HIV)-seronegative individual without known immunocompromised states. This patient suffered from chronic headaches for five years before presenting to us, with multiple past consultations resulting in misdiagnoses of migraines and tension-type headaches (TTH). The patient had developed new-onset warning signs in the last month after which neuroimaging was done, which showed features of increased intracranial pressure. Cerebrospinal fluid (CSF) analysis revealed Cryptococcus neoformans. The patient received amphotericin B alongside flucytosine, and he underwent three therapeutic lumbar punctures (LP) to relieve symptoms from raised intracranial pressure. Within two weeks, he showed significant improvement in headaches and was discharged in a healthy state. The patient was doing fine two months post discharge. This case emphasizes the necessity of ruling out red flag signs before diagnosing primary headaches. In clinical practice, if any patient shows poor response to medications despite adequate compliance, a thorough evaluation is required to rule out serious causes of headache, with a low threshold for neuroimaging.

Navigating the Knowledge of Risk Factors, Warning Signs, of Stroke - A Community-Based Cross-Sectional Study Among Saudi Adults in Riyadh Saudi Arabia.

Background: The incidence of stroke is increasing in everyday life as a result of modifiable cerebrovascular risk factors and aging. Therefore, the goal of this study was to assess knowledge of the risk factors, and warning signs, of stroke and to determine associated demographic factors among individuals living in Riyadh, Saudi Arabia. Methods and Materials: A cross-sectional online study using a convenience sampling of general population living in Riyadh was carried out over three months in 2023 using a series of questionnaires that was adopted from the previous study. Before data collection, the study tool was subjected to pilot testing among a small sample of individuals to validate for consistency and reliability. The data was collected using social media platforms. A statistical package for the social science (SPSS version 27) was used. Results: Four hundred and sixty-two individuals completed the survey. Among those 69.5%, identified hypertension as a risk factor for stroke followed by hyperlipidemia (42.9%), heart disease (44.8%). In addition, most of the respondents (n = 332, 71.9%) knew that numbness or weakness of the face and/or limbs of the body was a warning sign of stroke. In this, 73.5% (n=249) of the respondents agreed that if they saw an individual suffering from a stroke, they would like to take the patient to the hospital immediately. However, there was a significant association between the knowledge of the respondents about the risk factor of stroke and educational degree (p=0.011), and parents working in healthcare settings (p =0.015). Conclusion: In conclusion it was observed that a significant respondents had an adequate knowledge of stroke risk factors, while most were unaware of the early warning signs of a stroke. To promote primary prevention and early management/outcomes, we advise that future regional campaigns focus on raising knowledge and recognition of stroke symptoms.

24-Hour warning signs for adolescent suicide attempts.

BACKGROUND: Little is known about when youth may be at greatest risk for attempting suicide, which is critically important information for the parents, caregivers, and professionals who care for youth at risk. This study used adolescent and parent reports, and a case-crossover, within-subject design to identify 24-hour warning signs (WS) for suicide attempts. METHODS: Adolescents (N = 1094, ages 13 to 18) with one or more suicide risk factors were enrolled and invited to complete bi-weekly, 8-10 item text message surveys for 18 months. Adolescents who reported a suicide attempt (survey item) were invited to participate in an interview regarding their thoughts, feelings/emotions, and behaviors/events during the 24-hours prior to their attempt (case period) and a prior 24-hour period (control period). Their parents participated in an interview regarding the adolescents' behaviors/events during these same periods. Adolescent or adolescent and parent interviews were completed for 105 adolescents (81.9% female; 66.7% White, 19.0% Black, 14.3% other). RESULTS: Both parent and adolescent reports of suicidal communications and withdrawal from social and other activities differentiated case and control periods. Adolescent reports also identified feelings (self-hate, emotional pain, rush of feelings, lower levels of rage toward others), cognitions (suicidal rumination, perceived burdensomeness, anger/hostility), and serious conflict with parents as WS in multi-variable models. CONCLUSIONS: This study identified 24-hour WS in the domains of cognitions, feelings, and behaviors/events, providing an evidence base for the dissemination of information about signs of proximal risk for adolescent suicide attempts.

Clinical Knowledge, Perceptions, and Communication Confidence Regarding the Development of Thyroid Cancer --A Cross-Sectional Study of Clinical Medical Students in Chongqing, Southwest China.

Purpose: Medical students play an essential role in providing disease consultation for patients. Despite the rapid increase in thyroid disease, there are few data on how well Chinese medical students master the knowledge of thyroid diseases. This study aims to evaluate the clinical knowledge, perception, and clinical communication confidence of medical students on thyroid cancer (TC). Patients and Methods: This cross-sectional study was carried out among medical students of Chongqing Medical University. An anonymous, self-administered questionnaire distributed from December 2022 to February 2023 included items on demographics and other information, the warning signs of cancer, perception regarding a person's chance of developing cancer, and clinical communication confidence. Descriptive analysis, difference analysis, and correlation analysis were carried out. Results: A total of 226 medical students participated in the survey. Most students (n=191, 84.5%) had heard of TC, while only a few (n=10, 4.4%) regularly performed thyroid self-examination. One hundred and eighty-four students (81.4%) agreed that an unexplained lump or swelling could be a sign of cancer. There were significant differences in thyroid clinical knowledge in relation to gender (P<0.001), major (P=0.026), and thyroid disease (P=0.030). Clinical communication confidence showed significant differences in year of study (P=0.002), major (P=0.048), and graduate major (P<0.001). There was a correlation between clinical confidence and year of study (r=0.261, P<0.001). Conclusion: Most medical students have sufficient clinical knowledge on TC prevention, but there are still misconceptions related to TC screening. In addition, medical students lack confidence in communicating with patients. Comprehensive communication training should be integrated into the medical curriculum and clinical activities should be initiated earlier.

[Diagnosis and treatment of adult patients with inborn errors of immunity].

Primary immunodeficiency diseases (PID) are caused by abnormalities in molecules involved in the immune system, and there are nearly 500 genes associated with PID. The symptoms are not only susceptibile to infectious diseases but also to autoimmune diseases, malignancies, autoinflammatory diseases, and allergies. Thus, these diseases are considered inborn errors of immunity (IEI) rather than PID. IEI is typically thought to occur in childhood because IEI is associated with a genetic variant, but there are also several adult-onset IEIs. The same 10 warning signs used to diagnose IEI in children are used to diagnose the condition in adults as well, who are then given a definitive genetic diagnosis after a 4-step diagnostic process. In addition to prophylactic antimicrobial agents and immunoglobulin replacement therapy, allogeneic hematopoietic cell transplantation (HCT) is performed as a curative therapy in some patients with IEI. However, in adult patients with IEI, HCT may have to be stopped due to complications. Adult patients with IEI need to be promptly assessed for HCT, and HCT must be done before complications increase.

Healthcare utilization prior to a diagnosis of young-onset Alzheimer's disease: a nationwide nested case-control study.

OBJECTIVE: Our aim was to identify changes in healthcare utilization prior to a young-onset Alzheimer's disease diagnosis. METHODS: In a retrospective incidence density matched nested case-control study using national health registers, we examined healthcare utilization for those diagnosed with young-onset Alzheimer's disease in Danish memory clinics during 2016-2018 compared with age- and sex-matched controls. Negative binomial regression analysis produced contact rate ratios. RESULTS: The study included 1082 young-onset Alzheimer's disease patients and 3246 controls. In the year preceding diagnosis, we found increased contact rate ratios for all types of contacts except physiotherapy. Contact rate ratios for contacts with a general practitioner were significantly increased also > 1-5 and > 5-10 years before diagnosis. The highest contact rate ratios were for psychiatric emergency contacts (8.69, 95% CI 4.29-17.62) ≤ 1 year before diagnosis. INTERPRETATION: Results demonstrate that young-onset Alzheimer's disease patients have increased healthcare utilization from 5 to 10 years prior to diagnosis. Awareness of specific alterations in health-seeking behaviour may help healthcare professionals provide timely diagnoses.

Prodromal Symptoms in Patients Presenting With Myocardial Infarction.

Background Prodromal symptoms are warning signs of an impending acute myocardial infarction (AMI). However, they are often overlooked by both patients and primary clinicians, and little is known about them. Therefore, this study aims to assess the frequency and types of prodromal symptoms in patients with AMI. Methodology This descriptive cross-sectional study was conducted at a tertiary care cardiac center. Consecutive patients diagnosed with AMI within the last week were evaluated for prodromal symptoms. The prodromal symptoms included chest pain, chest heaviness, chest burning, palpitations, fatigue, sleep disturbance, shortness of breath (SOB), dizziness, anxiety, sudden heat or cold, back pain, and vomiting. Results In a sample of 242 patients, 79.6% were males, with a mean age of 54.7 ± 12.2 years, and 179 (74%) were diagnosed with ST-segment elevation myocardial infarction (STEMI). Among the participants, 142 (58.7%) showed no prodromal symptoms. Among those with prodromal symptoms, chest pain was the predominantly reported prodromal symptom with a frequency of 68%, followed by chest heaviness at 44%, palpitations at 42%, shortness of breath at 34%, and chest burning at 27%. Unusual fatigue in 23% and sleep disturbance in 22% of the patients were also reported. Conclusion The findings from this study revealed that prodromal symptoms were present in a significant proportion of acute myocardial infarction (MI) cases, with more than four in 10 patients reporting these early warning signs. The most commonly observed prodromal symptoms were chest pain, chest heaviness, palpitations, shortness of breath, and chest burning. The timely identification of these symptoms can help prevent infarction, thereby reducing the burden of heart failure and other related mortalities.

Hierarchical network structure as the source of hierarchical dynamics (power-law frequency spectra) in living and non-living systems: How state-trait continua (body plans, personalities) emerge from first principles in biophysics.

Living systems are hierarchical control systems that display a small world network structure. In such structures, many smaller clusters are nested within fewer larger ones, producing a fractal-like structure with a 'power-law' cluster size distribution (a mereology). Just like their structure, the dynamics of living systems shows fractal-like qualities: the timeseries of inner message passing and overt behavior contain high frequencies or 'states' (treble) that are nested within lower frequencies or 'traits' (bass), producing a power-law frequency spectrum that is known as a 'state-trait continuum' in the behavioral sciences. Here, we argue that the power-law dynamics of living systems results from their power-law network structure: organisms 'vertically encode' the deep spatiotemporal structure of their (anticipated) environments, to the effect that many small clusters near the base of the hierarchy produce high frequency signal changes and fewer larger clusters at its top produce ultra-low frequencies. Such ultra-low frequencies exert a tonic regulatory pressure that produces morphological as well as behavioral traits (i.e., body plans and personalities). Nested-modular structure causes higher frequencies to be embedded within lower frequencies, producing a power-law state-trait continuum. At the heart of such dynamics lies the need for efficient energy dissipation through networks of coupled oscillators, which also governs the dynamics of non-living systems (e.q., earthquakes, stock market fluctuations). Since hierarchical structure produces hierarchical dynamics, the development and collapse of hierarchical structure (e.g., during maturation and disease) should leave specific traces in system dynamics (shifts in lower frequencies, i.e. morphological and behavioral traits) that may serve as early warning signs to system failure. The applications of this idea range from (bio)physics and phylogenesis to ontogenesis and clinical medicine.

Awareness of Stroke Risk Factors and Warning Signs Among Diabetic Patients in the Aseer Region, Saudi Arabia: A Cross-Sectional Study.

Objective This study aimed to determine the awareness of stroke risk factors and warning signs among diabetic patients in the Aseer Region, Saudi Arabia. Methods We adopted a cross-sectional study involving 314 participants in the Aseer Region, Saudi Arabia between February 27, 2023, and April 20, 2023. The target population was diabetic patients whose database was obtained from various health institutions. The questionnaire was then distributed to the respondents after obtaining informed consent. The data were analyzed using SPSS Statistics version 27.0.1.0 (IBM Corp., Armonk, NY, USA) to obtain important insights. Results The majority of the respondents (69.11%) demonstrated a good level of knowledge, while 30.89% had poor knowledge. A good proportion of the respondents (68.47%) knew about stroke, while 73.89% knew it primarily affects the brain. Most respondents claimed that elderly people were at higher risk of attack (52.55%) and that the younger population was also prone to stroke (64.97%). The respondents identified hypertension (74.52%), smoking (72.61%), diabetes (71.66%), and high blood cholesterol (68.47%) as the main risk factors for stroke. The participants also demonstrated a very good understanding of the warning signs, with difficulty speaking (80.57%) and the weakness or inability to move one-half of the body (85.35%) being the most common signs. Conclusion The findings in this study indicated a good level of understanding and awareness of stroke, its risk factors, and warning signs (69.11%). The older respondents and people with a higher level of education demonstrated more knowledge. The two variables, age and education, had a statistically significant relationship with the knowledge of stroke. The common risk factors associated with stroke were identified as hypertension, smoking, diabetes, and high blood cholesterol. The respondents demonstrated good knowledge of the warning signs, with the vast majority asserting that difficulty in speaking, decreased sensation, and weakness or inability to move one-half of the body are common warning signs.

An adapted management of early warning signs of relapse questionnaire: Validity and reliability.

BACKGROUND: Self-management of early warning signs of relapse is critical when it comes to having an impact on the relapse rate and developing methods to successfully handle and manage those signs of relapse. OBJECTIVE: The purpose of this study was to test the validity and reliability of the adapted management of early warning signs of relapse questionnaire. METHODS: Consisted of two main steps: first, adapting and validating, which involved a literature review, a panel of experts, the calculation of the CVI, the Kaiser-Meyer-Olkin (KMO) test, Bartlett's test of sphericity, and exploratory factor analysis (EFA); and secondly, reliability analysis, using the test-retest method, to assess the questionnaire's internal consistency (Cronbach's alpha) and reproducibility (intraclass correlation coefficient-ICC). RESULTS: The results showed that the questionnaire adapted was valid and reliable and can represent each item of the questionnaire for assessing the self-management of early warning signs of relapse. CONCLUSION: This proves that all 20 items used to assess it are appropriate for assessing the effectiveness of the patients' and their primary caregivers' abilities to self-manage early warning signs of relapse.

COVID-19 and Sinophobia: Detecting Warning Signs of Radicalization on Twitter and Reddit.

Hate crimes and hateful rhetoric targeting individuals of Asian descent have increased since the outbreak of COVID-19. These troubling trends have heightened concerns about the role of the Internet in facilitating radicalization. This article explores the existence of three warning signs of radicalization-fixation, group identification, and energy bursts-using data from Twitter and Reddit. Data were collected before and after the outbreak of COVID-19 to assess the role of the pandemic in affecting social media behavior. Using computational social science and Natural Language Processing techniques, we looked for signs of radicalization targeting China or Chinese individuals. Results show that fixation on the terms China and Chinese increased on Twitter and Reddit after the pandemic began. Moreover, tweets and posts containing either of these terms became more hateful, offensive, and negative after the outbreak. We also found evidence of individuals identifying more closely with a particular group, or adopting an "us vs. them" mentality, after the outbreak of COVID-19. These findings were especially prominent in subreddits catering to self-identified Republicans and Conservatives. Finally, we detected bursts of activity on Twitter and Reddit following the start of the pandemic. These warning signs suggest COVID-19 may have had a radicalizing effect on some social media users. This work is important because it not only shows the potential radicalizing effect of the pandemic, but also demonstrates the ability to detect warning signs of radicalization on social media. This is critical, as detecting warning signs of radicalization can potentially help curb hate-fueled violence.

An Initiative to Improve Postpartum Discharge Education.

OBJECTIVE: To evaluate an online POST-BIRTH Warning Signs (PBWS) project focused on improving nurses' knowledge and how they teach individuals in the postpartum period about potential complications. DESIGN: Quality improvement project with exploratory pretest/posttest. SETTING: Seventy hospitals with maternity services throughout the United States. PARTICIPANTS: A sample of 2,363 registered nurses. INTERVENTION/MEASUREMENTS: An online educational program with four surveys and a chart audit tool were used as evaluation measures. RESULTS: There was an 11% increase in nurses' knowledge after the online course intervention. A majority of nurses reported that they would improve how they educate patients and families about PBWS, that they would change their clinical practice based on what they learned, and that their facility implemented a protocol to educate patients about PBWS after the implementation of the course. The nurses' reported confidence in their teaching increased 59% after implementation of the course. CONCLUSION: The majority of maternal deaths in the United States occur during the postpartum period. Therefore, it is vital that nurses provide standardized and structured educational messaging when teaching individuals in the postpartum period about signs and symptoms of potential complications. This quality improvement project demonstrated that the PBWS online education course was associated with an increase in nurses' knowledge and confidence when teaching about potential complications that can arise during the postpartum period.
