Abstract:
Abstract Depression is a common comorbid mental illness in eating disorders (EDs). Network theory focuses on interactions between symptoms, but findings from network analyses of EDs and depression need to be replicated to make reliable claims about the nature of symptomatic interplay. We used cross-sectional data of 366 online-recruited participants with clinically elevated ED symptomatology and constructed a regularized partial correlation network with ED and depression symptoms. To determine each symptom's influence, we calculated expected influence (EI) and bridge EI to identify symptoms that bridged symptoms of depression and ED. Concerns that others see one eat, fear of weight gain, and fear of loss of control over eating were especially important among the ED symptoms. Loss of interest and feeling sad were the key depression symptoms. Eating in secret and low self-esteem emerged as potential bridge symptoms between clusters. These findings regarding bridge symptoms partially overlap with prior network analyses in nonclinical and clinical samples. Future studies that investigate symptom interplay via a longitudinal design to deduce causality are needed.

Abstract:
Heart failure (HF) symptoms are known to influence depressive symptoms, yet a symptom profile has not been identified. HF symptoms relative to symptom experience (frequency, severity, interference with physical activity and enjoyment of life) associated with depressive symptoms were examined. Data from three HF studies ( N = 308) which used the Heart Failure Symptom Survey were included in this cross-sectional secondary analysis. Supervised classification for and identification of symptoms most associated with depressive symptoms were accomplished using random forest algorithms via conditional inference trees. The HF symptom profile associated with depressive symptoms across all four symptom experience domains included fatigue, dizziness, and forgetfulness/difficulty concentrating. Abdominal bloating, worsening cough, and difficulty sleeping were also important, but did not consistently rank in the top 5 for symptom importance relative to all symptom experience domains. Symptom profiling may enhance early identification of patients at risk for depressive symptoms and inform symptom management interventions.

Abstract:
If negative symptoms represent a distinct class of schizophrenic symptoms, they should, to paraphrase Bleuler (1911), be more closely related to each other than they are to other schizophrenic symptoms. The first part of this statement, that negative symptoms are intrinsically related to each other, has received considerable experimental support (Andreasen, this volume; Mortimer et al, this volume). The second, that negative symptoms are unrelated to other schizophrenic symptoms, has been somewhat more unevenly investigated.

Abstract:
The study examines to what degree well-documented present and life-time psychotic symptoms in a group of former psychiatric inpatients are ascertained when using the Diagnostic Interview Schedule (DIS). The Inpatient Multidimensional Psychiatric Scale (IMPS) and the Manual for the Assessment and Documentation of Psychopathology/Diagnostische Sichtlochkartei (AMDP/DiaSika) Interview-Checklist approach were used for the “clinical” evaluations of symptoms. The results indicate fair concordance between the two clinical approaches and the DIS with regard to the presence of any delusional or hallucination symptoms. Low to poor agreement was found in the assessment of many of the rather specific hallucinations and delusions. Generally, the concordance found was higher when compared to the more clinical AMDP/DiaSiKa approach than to the IMPS. More detailed comparisons with diagnostic subgroups of schizophrenic and schizoaffective patients substantiated the findings in the overall sample. Overall it was reconfirmed that the DIS approach is limited to those patients who are cooperative and at least partly remitted.

Abstract:
The purpose of the study was to investigate the perceived anxiety experienced by coronary care nurses working eight- and 12-hour work shifts. It was hypothesized that length of shift work affects the before- and after-shift anxiety for nurses working eight or 12-hour work shifts. Anxiety differences between the eight- and 12-hour work shifts were examined as well as differences between the before- and after-shift anxiety for each length of shift.Thirty-two (32) coronary care nurses from a general medical and surgical hospital in the Midwest volunteered to participate in the research. The sample consisted of all females (18 Registered Nurses, nine Licensed Practical Nurses, three charge nurses, a supervisory nurse, and a rehabilitation nurse). The nurses had voluntarily selected the eight- or 12-hour length of shift work and understood that they would be committed to work that shift for one year. Twelve nurses worked the eight-hour shift; 20 nurses chose the new 12-hour shift.The State Anxiety Inventory (SAI) was used to measure the nurses' before- and after-shift anxiety. Baseline data were collected from the nurses prior to the initiation of the 12-hour shift. The Box-Jenkins Time Series Analysis was used to analyze the daily before- and after-shift anxiety scores and to establish a forecasted trend for both the eight- and 12-hour shifts.The first finding was that the before-shift anxiety scores for the eight-hour workers declined, while the anxiety scores for the 12-hour workers increased, following the implementation of the 12-hour shift. The same trend was forecast for the after-shift anxiety scores. The eight-hour nurses' after-shift anxiety scores declined while the 12-hour nurses' anxiety scores increased. A transfer function was conducted for both the eight-hour and 12-hour before- and after-shift anxiety scores. No predictive trend could be established for the eight-hour anxiety scores; however, the 12-hour after-shift anxiety scores were found to be consistently higher than before-shift anxiety scores.

Abstract:
A predominance of symptomology related to neurological dysfunction has been reported for at least some learning disabled (LD) students. This investigation examined the self-reported neuropsychological symptoms of LD and normal students in grades 3 through 12. Determination of group membership based on the childrens' responses to items on the Neuropsychological Symptom Inventory (NSI) was made for all subjects in the study.A discriminant analysis was conducted in order to determine the degree of group separation based on the item responses and which reported symptoms add significantly to that separation. Out of 40 possible items, 19 added to the discriminant function. Prediction of group membership was accomplished with a high degree of accuracy. Nearly 80% of the total population examined were correctly classified according to actual group membership. Of the LD population, 32% were identified as normal but only 16% of the normal population were misdiagnosed as LD. Additionally, nine individual symptoms were identified as reported by a greater percentage of LD students than normals.The results of this investigation suggest that the NSI as a screening instrument may be valuable for some populations. The 80% accuracy rate with the low number of false-positives (16%) is extremely encouraging. Additional research with the NSI to validate the presence of the symptomology reported would add to the already existing data related to the neuropsychological implications related to learning disabilities.

Full text
Abstract:
Volume 1 is divided into 3 parts as follows: Part 1 (Review Paper) discusses the admissibility of psychometric evidence of cognitive malingering in UK criminal law courts. The paper opens with a historical account of psychologists as expert witnesses, highlighting significant advances relevant to malingering. This sets the context for a discussion about current developments in policy and specifically the creation of a UK standard for the admissibility of scientific evidence. The penultimate section outlines the statistical and methodological issues which challenge the development of empirical cognitive measures of malingering. The paper closes with a discussion of future directions for research and practice in presenting psychological evidence in court. Part 2 (Empirical Paper) reports on a study testing the utility of a battery of measures to identify simulating malingerers from healthy controls and psychiatric inpatients. The battery of measures were chosen for their different approaches to detecting malingerers. An additional qualitative interview was given to the simulating malingerers to investigate the strategies they used to fake the tests. The performance of the test battery was compared to a pre-existing screening tool for malingering. The results were discussed with reference to implications for research and practice. Part 3 (Critical Appraisal) reflects on the process of undertaking the research. It discusses the generalisability of the findings when using a simulating malingering design, the utility of measuring reaction time to detect malingering, difficulties in the recruitment of inpatients, the array of choices in selecting the test battery and the clinical applications of the research.

Abstract:
Anxiety is a chronic illness especially during the Covid and post-pandemic era. It’s important to diagnose anxiety in its early stages. Traditional Machine learning (ML) methods have been developmental intense procedures to detect mental health issues, but Automated machine learning (AutoML) is a method whereby the novice user can build a model to detect a phenomenon such as Generalized Anxiety Disorder (GAD) fairly easily. In this study we evaluate a popular AutoML technique with recent chat engine (Discord) conversation dataset using anxiety hashtags. This multi-symptom AutoML Random Forest predictive model is at least 75+% accurate with the most prevalent symptom, namely restlessness. This could be a very useful first step in diagnosing GAD by medical professionals and their less skilled hospital’s IT area using pre diagnostic textual conversations. But it lacks high quality in predicting GAD in most symptoms as found by a low 50% precision on most symptoms (except 5). The AutoML technology is quicker for IT professionals and gives a decent performance, but it can be improved upon by more sophisticated ANN methods like Convolution neural networks that plug AutoML’s symptom’s deficiencies with at least 80+% precision and 0.4+% in F1 score, namely in detecting poorly predicted symptoms of concentration and irritability.

Abstract:
Online users have generated a large amount of health-related data on medical forums and search engines. However, exploiting these rich data for orienting patient online and assisting medical checkup offline is nontrivial due to the sparseness of existing symptom-disease links, which caused by the natural and chatty expressions of symptoms. In this paper, we propose a novel and general representation learning method ContextCare for human generated health-related data, which learns the latent relationship between symptoms and diseases from the symptom-disease diagnosis network for disease prediction, disease category prediction and disease clustering. To alleviate the network sparseness, ContextCare adopts regularizations from rich contextual information networks including a symptom co-occurrence network and a disease evolution network. Therefore, our representations of symptoms and diseases incorporate knowledge from these three networks. Extensive experiments on medical forum data demonstrate that ContextCare outperforms the state-of-the-art methods in disease category prediction, disease prediction and disease clustering.

Abstract:
New methods of information presentation and interface design are changing the working conditions in the modern Nuclear Power Plant (NPP) control room. Symptom-oriented EOPs (SOPs) with their structures and practical application are described. The Computerized Symptom-oriented Operating Procedures (CSOP) is researched, which can help the operator analyze all the symptom signals of steam generator tubes rupture (SGTR) and provide the computerized procedures corresponding to the symptom signals. This paper analyzes the accident of SGTR; the accident management of SGTR is important in reactor safety because SGTR is one of the relatively high-frequency events in pressurized water reactors PWRs. The symptom signals of SGTR and the possible accidents corresponding to the symptom signals are analyzed. The homologous measures of symptoms are summarized. The disposal of SGTR adopts the method of based on symptoms. The programs are developed by VxWorks that is a real-time operating system. The debugging of programs is processed on simulator. The test results indicated that the programs can provide operating procedures according to the symptoms of accidents. After adopting the Computerized Emergency Operating Procedures, the labor intensity and mental burden of operators are lightened. Computerized Emergency Operating Procedures can enhance the reliability, safety and efficiency of Nuclear Power Plant.

Abstract:
Corona virus disease is an infectious disease induced by a family of viruses that can cause common cold and severe acute respiratory syndrome (SARS).This research work was designed to shed light on the different presentation forms, especially the unusual ones of the disease as an attempt to make early diagnosis for better and efficient treatment and prevention of the disease.A sample of 203 subjects who have had corona disease were questioned about the symptoms they were complaining of during the illness. Correlation coefficient study was conducted to declare the relationship between the different symptoms especially the unusual ones and the disease, among the symptoms themselves, certain symptoms with the age group, as well as the gender.The results showed positive correlation between many of the usual symptoms and the disease for instance, fever, headache, cough, dyspnea, malaise, muscle and joint pain, dizziness, loss of smell and appetite, running nose, sore throat, nausea, vomiting, and diarrhea. No significant correlation could be detected with the unusual symptoms like, elevated blood pressure, conjunctival congestion, amnesia, and decreased concentration, skin rash, loss of consciousness, intestinal colic and gastric pain.According to the available results no specific symptom could be attributed to a given age group or gender with the exception of the neurological symptoms in the form of amnesia, loss of consciousness, and decreased concentration. These findings were found to be firmly correlated with the severity of fever. The authors postulate that these symptoms can be attributed to the temporary reduction in the number of neurotransmitters molecules of the brain. Further work is needed to provide evidence in support of this postulation. In conclusion, for early diagnosis and therefore to achieve efficient treatment of corona disease, unusual presentation must be kept in mind. Fever must be delt with seriously and effectively to prevent or minimize the development of neurological symptoms. Using all means of audio, video, and social media to spread the information about the disease will have a crucial role in slowing the spread of the disease especially the new strains.

Abstract:
It is definitely necessary to train pilots for hypoxia symptoms, as accident reports, both military and civilian has proved. Traditional training was done in the altitude chamber, a device that simulated with a great degree of fidelity the physiological problems encountered in flight. However, perils of the altitude chamber, decompression sickness being the most cited upon, make this a less than perfect training modality, although the altitude chamber realism stays paramount. Recently there are reports have showed that hypoxia training in chamber is not full proof. Computer assisted learning in chamber it is still not deployed as far as our knowledge goes. A device for on ground hypoxia might be an answer, if not as replacement, at least as a complementary for this training problem. Method: We we have employed a ground hypoxia simulator, a commercially available medical grade device. The principle of on ground hypoxia demonstration is detailed, as well as the tests given for self evaluation. A comparison of recognized symptoms versus altitude chamber training was performed, based on the symptom check list form the ground simulator (basically the forms were the same, only one filled on the computer, the other one by hand). Results: The new method of training lead to improved symptom recognition, generally more symptoms being reported in the on-ground device. Most recognized symptoms were in the mental calculus and in the motor skills category. Statistically, there were no significant differences for symptoms distribution, p value ranging from 0.06 to 0.6, except for the mental symptom reporting (p=0.018, Z=2,36). Brief physiological insights on this difference ground are presented. The study design did not allow us to test computer training efficiency comparison (no way to deploy that in the altitude chamber). Conclusion: The on ground hypoxia training is a valid and useful complementary training method to the classic paradigm of altitude chamber training.

Abstract:
The mechanisms underlying the development of symptoms in response to virus infection remain to be discovered in plants. Insight into symptoms induced by potyviruses comes from evidence implicating the potyviral HC-Pro protein in symptom development. In particular, recent studies link the development of symptoms in infected plants to HC-Pro's ability to interfere with small RNA metabolism and function in plant hosts. Moreover, mutation of the highly conserved FRNK amino acid motif to FINK in the HC-Pro of Zucchini yellow mosaic virus (ZYMV) converts a severe strain into an asymptomatic strain, but does not affect virus accumulation in cucurbit hosts. The ability of this FINK mutation to uncouple symptoms from virus accumulation creates a unique opportunity to study symptom etiology, which is usually confounded by simultaneous attenuation of both symptoms and virus accumulation. Our goal was to determine how mutations in the conserved FRNK motif affect host responses to potyvirus infection in cucurbits and Arabidopsis thaliana. Our first objective was to define those amino acids in the FRNK motif that are required for symptoms by mutating the FRNK motif in ZYMV and Turnip mosaic virus (TuMV). Symptom expression and accumulation of resulting mutant viruses in cucurbits and Arabidopsis was determined. Our second objective was to identify plant genes associated with virus disease symptoms by profiling gene expression in cucurbits and Arabidopsis in response to mutant and wild type ZYMV and TuMV, respectively. Genes from the two host species that are differentially expressed led us to focus on a subset of genes that are expected to be involved in symptom expression. Our third objective was to determine the functions of small RNA species in response to mutant and wild type HC-Pro protein expression by monitoring the accumulation of small RNAs and their targets in Arabidopsis and cucurbit plants infected with wild type and mutant TuMV and ZYMV, respectively. We have found that the maintenance of the charge of the amino acids in the FRNK motif of HC-Pro is required for symptom expression. Reduced charge (FRNA, FRNL) lessen virus symptoms, and maintain the suppression of RNA silencing. The FRNK motif is involved in binding of small RNA species including microRNAs (miRNA) and short interfering RNAs (siRNA). This binding activity mediated by the FRNK motif has a role in protecting the viral genome from degradation by the host RNA silencing system. However, it also provides a mechanism by which the FRNK motif participates in inducing the symptoms of viral infection. Small RNA species, such as miRNA and siRNA, can regulate the functions of plant genes that affect plant growth and development. Thus, this binding activity suggests a mechanism by which ZYMVHC-Pro can interfere with plant development resulting in disease symptoms. Because the host genes regulated by small RNAs are known, we have identified candidate host genes that are expected to play a role in symptoms when their regulation is disrupted during viral infections. As a result of this work, we have a better understanding of the FRNK amino acid motif of HC-Pro and its contribution to the functions of HC-Pro, and we have identified plant genes that potentially contribute to symptoms of virus infected plants when their expression becomes misregulated during potyviral infections. The results set the stage to establish the roles of specific host genes in viral pathogenicity. The potential benefits include the development of novel strategies for controlling diseases caused by viruses, methods to ensure stable expression of transgenes in genetically improved crops, and improved potyvirus vectors for expression of proteins or peptides in plants.

Abstract:
Review question / Objective: Following the COVID-19 global outbreak, Long Covid is currently the most urgent global health problem. Primary clinical research have produced widely varying findings demonstrating the protective and even counterproductive effects of immunization against extended Covid. We used a systematic review and meta-analysis to examine the impact of pre- and post-Covid immunization for the prevention of extended Covid. Condition being studied: The main result is whether long Covid is present or absent, which is determined by whether one or more long Covid symptoms have persisted for more than three weeks following infection. The secondary result is whether or not each unique long-term Covid symptom is present. ICD10-CM was used to classify and define symptoms since research utilized several names for the same symptom. To ensure validity, we only examined long-lasting Covid symptoms mentioned in three or more research. We asked the authors of publications that merely provided information on the presence or absence of extended Covid to provide information on specific symptoms. We also wanted data that was stratified by the number of vaccine doses for studies that pooled data from pre-Covid vaccinations given in 1-dose and 2-dose regimens.

Abstract:
Background: Among the frequently reported symptoms in long-term COVID-19 syndrome, we can highlight olfactory disorders depression, anxiety, and fatigue. OD can affect people's physical and mental health and can lead to neuropsychiatric symptoms. Objective: Determine the prevalence of symptoms of depression, anxiety, and fatigue in patients with olfactory disorders induced by long-term COVID-19; and investigate this impact on the quality of life. Methods: The study included 30 patients with confirmed long-term COVID-19, with persistent complaints of olfactory dysfunction. OD was evaluated by the connecticut smell test. Neuropsychiatric disorders were evaluated by the fatigue severity and hospital anxiety and depression scales. Quality of life was accessed using the SF-36. Results: 70% of the patients had different degrees of hyposmia and 20% had anosmia. The most prevalent symptom was depression with 66.7% of the sample. More than half of patients also had symptoms of anxiety and fatigue (53,3% both). The most affected dimensions of SF-36 were emotional, vitality, role physical and mental health (36.6 ± 44.0, 44.3 ± 28.7, 47.5 ± 42.7, 49.8 ± 24.7 respectively). There was a moderate negative correlation between symptoms of depression and the physical role and mental health dimension. There was a moderate negative correlation between anxiety and general health, vitality, social functioning, and mental health dimensions. Symptoms of fatigue obtained a moderate negative correlation in the physical function dimension. Conclusion: The prevalence of symptoms of depression, anxiety and fatigue is high in patients with olfactory disorders induced by long-term COVID-19, with a negative impact on the quality of life of these patients, highlighting the role emotional aspect.
