RESUMO

BACKGROUND: The WHO has raised concerns about the psychological consequences of the current COVID-19 pandemic, negatively affecting health across societies, cultures and age-groups. METHODS: This online survey study investigated mental health, subjective experience, and behaviour (health, learning/teaching) among university students studying in Egypt or Germany shortly after the first pandemic lockdown in May 2020. Psychological assessment included stable personality traits, self-concept and state-like psychological variables related to (a) mental health (depression, anxiety), (b) pandemic threat perception (feelings during the pandemic, perceived difficulties in describing, identifying, expressing emotions), (c) health (e.g., worries about health, bodily symptoms) and behaviour including perceived difficulties in learning. Assessment methods comprised self-report questions, standardized psychological scales, psychological questionnaires, and linguistic self-report measures. Data analysis comprised descriptive analysis of mental health, linguistic analysis of self-concept, personality and feelings, as well as correlational analysis and machine learning. N = 220 (107 women, 112 men, 1 = other) studying in Egypt or Germany provided answers to all psychological questionnaires and survey items. RESULTS: Mean state and trait anxiety scores were significantly above the cut off scores that distinguish between high versus low anxious subjects. Depressive symptoms were reported by 51.82% of the student sample, the mean score was significantly above the screening cut off score for risk of depression. Worries about health (mental and physical health) and perceived difficulties in identifying feelings, and difficulties in learning behaviour relative to before the pandemic were also significant. No negative self-concept was found in the linguistic descriptions of the participants, whereas linguistic descriptions of feelings during the pandemic revealed a negativity bias in emotion perception. Machine learning (exploratory) predicted personality from the self-report data suggesting relations between personality and subjective experience that were not captured by descriptive or correlative data analytics alone. CONCLUSION: Despite small sample sizes, this multimethod survey provides important insight into mental health of university students studying in Egypt or Germany and how they perceived the first COVID-19 pandemic lockdown in May 2020. The results should be continued with larger samples to help develop psychological interventions that support university students across countries and cultures to stay psychologically resilient during the pandemic.

RESUMO

Since the end of 2019, the world has been facing an unpredicted COVID-19 pandemic with consequences for the economy, environment, society, and health. The COVID-19 pandemic has increased the risk of death, bringing unbearable psychological pressure upon people worldwide. For celiac patients, the pandemic may represent an additional burden concerning the inherent aspects of celiac disease (CD) that compromise these individuals' quality of life (QoL). Therefore, the objective of this study was to evaluate Brazilian celiac patients' QoL during the course of the COVID-19 pandemic caused by its outbreak and rapid spread and subsequent restrictive measures in addition to the dietary restrictions and other burdens caused by CD. This country-wide cross-sectional study was conducted using a self-administered instrument previously validated in Brazilian-Portuguese to investigate the QoL of individuals with CD. Data collected through the online self-administration of the Brazilian version of the celiac disease quality of life questionnaire (CDQ) comprised 674 CD individuals' responses. Although pandemics have historically posed a challenge for Brazilian population, this period was not associated with a negative impact on Brazilian CD individuals' QoL. During the pandemic, the QoL of Brazilian's with CD was more affected by gastrointestinal aspects than emotions and social aspects and worries. Gender, age, marital status, having (or not) children, occupation, and a positive test for COVID-19 did not affect CD individuals' QoL. However, the study revealed a larger burden and diminished QoL for individuals not following a gluten-free diet and those using antidepressants. Additional research is necessary to verify how the length of the pandemic will affect celiac individuals and then compare those outcomes compare to the COVID-19 period and after.

RESUMO

OBJECTIVE: To find out the moderating effect of emotion reactivity and several demographic variables following symptoms of post-traumatic stress disorder among individuals having undergone an amputation. METHODS: The cross-sectional study was conducted from March to July 2015 at the Government College University, Lahore, Pakistan, and comprised individuals, enrolled from difference orthopaedic and rehabilitation centres, aged 18-60 years having undergone amputation of upper or lower limb either because of diseases, like diabetes, gangrene, cancer ulcer, or because of traumatic injuries, like road accident, electrical shock. Assessment of the study variables was done using the Emotion Reactivity Scale and the Post-traumatic Stress Disorder Checklist-5. Data was analysed using SPSS 21. RESULTS: Of the 160 subjects, 117(72%) were males and 43(28%) were females. The overall mean age was 38.45±13.17 years. Upper limb amputation cases were 17(10.6%), lower limb 138(86.2%) and both upper and lower limb amputation 5(3.2%). Amputation due to any disease was the case with 76(47.5%) subjects, while traumatic injury was the cause in 84(52.5%). There was a significant positive association of emotional reactivity with symptoms severity of post-traumatic stress disorder (p<0.05). CONCLUSIONS: Post-amputation effects were found to have a significant impact on individual emotions, and traumatic flashbacks had a leading role in the development of post-traumatic stress disorder symptoms severity.

RESUMO

AIMS: Alienation towards parents often occurs when parents divorce; however, it can also occur when one or both parents leave for work for more than 6 months. Our previous investigation has confirmed a high level of feelings of alienation towards parents among Chinese left-behind children. However, the longitudinal prediction of alienation on children's mental health outcomes remains largely unknown. This study aims to observe the prediction of alienation towards parents on children's depression 12 months later and potential mediators and moderators. METHODS: A total of 1090 Chinese left-behind children took part in this 12-month follow-up investigation, using the Chinese version of the Inventory of Alienation towards Parents (IAP), the Children's Depression Inventory (CDI), the Adolescent Self-Rating Life-events Checklist (ASLEC), and the Adolescent Resilience Scale. RESULTS: Alienation towards parents was high (16.42 ± 7.27 for mother, 15.63 ± 7.17 for father) in left-behind children, and 21.01% of children reported depression. Alienation towards parents predicted current depression of children directly and later depression indirectly; children's alienation toward their mothers was a stronger predictor of depression than alienation towards fathers. In models, stressful life-events acted as a risk mediator. Previous depression was the strongest risk predictor, resilience was the strongest protective factor, and duration of fathers' absence and parents' marital status moderated the predictive effects. CONCLUSIONS: This study is among the first to longitudinally confirm that alienation towards parents is a predictor of children's later depression. The results provide important suggestions for families and schools; i.e. to prevent depression in left-behind children, parent-child bonds especially alienation towards mothers, should be carefully considered, and individuals with more negative life-events and weaker resilience need further attention.

RESUMO

OBJECTIVE: Based on the TGAM PCB module, a system of emotion control using audio-visual feedback is designed. METHODS: TGAM collects EEG information through the electrode in contact with the forehead skin. The system analyzes the user's emotion through the STM32F103ZET6 of the main control chip, and finally controls the control end of the system to regulate the user's emotion. RESULTS: It can be seen from the test results that the system can precisely recognize the user's emotions, and at the same time effectively adjust the user's emotions from both audio-visual aspects. CONCLUSIONS: The system has high recognition accuracy and good adjustment effect.

RESUMO

ZHANG Ren, the chief physician, believes that diabetic retinopathy is located at eye and closely related to qi and yin. He proposes the treatment principle of this disease, i.e. combination of the primary and the secondary, in which, taking the eye as the treatment target and focusing on the symptoms. Acupuncture is provided for activating blood circulation and resolving stasis at the extra points, e.g. Xinming and Shangjianming, and also meridian points, e.g. Cuanzhu (BL 2) and Tongziliao (GB 1). The comprehensive application is emphasized with filiform needle, dermal needle and acupoint injection. Moreover, the mental and physical conditions are treated simultaneously to regulate emotions and the preventive idea is suggested on early treatment and persistent treatment.

RESUMO

The potential effect mechanism of acupuncture for perimenopausal syndrome is analyzed and summarized from five aspects, i.e. the influence on reproductive endocrine system, the regulation on nervous system, the improvement of immune function, the intervention on free radical metabolism and the regulation of adverse emotions. It is believed the mechanism research of acupuncture in the treatment of perimenopausal syndrome should be deepened in terms of acupoint specificity and the influence of acupoint compatibility based on the characteristics of acupuncture therapy itself. In clinic, the research on therapeuticmethods and treatment frequency should be enhanced.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has resulted in significant uncertainty for the global population. However, since not all population groups experience the impacts of the pandemic in the same way, the objective of this study was to identify the individual characteristics associated with the feeling of uncertainty during the lockdown that commenced in March 2020 in Greece. The study used data from the "Public Opinion in the European Union (EU) in Time of Coronavirus Crisis" survey. The sample consisted of 1050 individuals aged between 16 and 54 years. According to the analysis, which was based on a logistic regression model, the emotional status of older individuals, those who experienced income and job losses since the beginning of the pandemic, and middle-class and high-class individuals, is more likely to be described as a feeling of uncertainty. In addition, the emotional status of individuals with less concern for their own health and that of family and friends is less likely to be described as a feeling of uncertainty. Although the results related to age, income, and job losses, as regards concern for health, agree with the international literature, the limited health literacy of lower-class individuals may explain the reduced likelihood of their experiencing feelings of uncertainty. The results confirm the international literature describing several aspects of uncertainty due to the COVID-19 crisis.

RESUMO

Recognition of emotions from physiological signals, and in particular from electroencephalography (EEG), is a field within affective computing gaining increasing relevance. Although researchers have used these signals to recognize emotions, most of them only identify a limited set of emotional states (e.g., happiness, sadness, anger, etc.) and have not attempted to predict exact values for valence and arousal, which would provide a wider range of emotional states. This paper describes our proposed model for predicting the exact values of valence and arousal in a subject-independent scenario. To create it, we studied the best features, brain waves, and machine learning models that are currently in use for emotion classification. This systematic analysis revealed that the best prediction model uses a KNN regressor (K = 1) with Manhattan distance, features from the alpha, beta and gamma bands, and the differential asymmetry from the alpha band. Results, using the DEAP, AMIGOS and DREAMER datasets, show that our model can predict valence and arousal values with a low error (MAE < 0.06, RMSE < 0.16) and a strong correlation between predicted and expected values (PCC > 0.80), and can identify four emotional classes with an accuracy of 84.4%. The findings of this work show that the features, brain waves and machine learning models, typically used in emotion classification tasks, can be used in more challenging situations, such as the prediction of exact values for valence and arousal.

RESUMO

The aim of this study was to explore the knowledge, emotions and perceived stressors by healthcare workers who were in contact with infected patients during the COVID-19 outbreak. An online cross-sectional survey was applied. Data were collected from N = 263 healthcare workers in Tabasco State, Mexico. We developed and administered a questionnaire, which consisted of sociodemographic characteristics, plus four sections. The sections evaluated were (1) knowledge of COVID-19; (2) feelings/emotions during the COVID-19 outbreak; (3) factors that caused stress and (4) factors that helped to reduce stress. Surveyed individuals were divided into three groups: physicians, nurses and other healthcare workers. When we evaluated their knowledge of COVID-19 we observed that the majority of healthcare workers in the three groups reported that they knew about COVID-19. Physicians indicated that they felt insecure about practicing their profession (62.5%) due to the high risk of being in contact with SARS-CoV-2. With regards to stressor factors, the risk of transmitting COVID-19 to their families was the main factor causing moderate to high stress (95.4%). Finally, we found that "your profession puts your life at risk" was the only factor associated with feeling nervous and scared (PR: 3.15; 95% CI: 1.54-6.43). We recommended health education campaigns, introductory courses on COVID-19 and other infectious diseases, management protocols and the provision of protection equipment to health workers in order to reduce personal and professional fears of contagion and to improve the health system in Mexico when facing epidemics.

RESUMO

The theory of modern organizations considers emotional intelligence to be the metric for tools that enable organizations to create a competitive vision. It also helps corporate leaders enthusiastically adhere to the vision and energize organizational stakeholders to accomplish the vision. In this study, the one-dimensional convolutional neural network classification model is initially employed to interpret and evaluate shifts in emotion over a period by categorizing emotional states that occur at particular moments during mutual interaction using physiological signals. The self-organizing map technique is implemented to cluster overall organizational emotions to represent organizational competitiveness. The analysis of variance test results indicates no significant difference in age and body mass index for participants exhibiting different emotions. However, a significant mean difference was observed for the blood volume pulse, galvanic skin response, skin temperature, valence, and arousal values, indicating the effectiveness of the chosen physiological sensors and their measures to analyze emotions for organizational competitiveness. We achieved 99.8% classification accuracy for emotions using the proposed technique. The study precisely identifies the emotions and locates a connection between emotional intelligence and organizational competitiveness (i.e., a positive relationship with employees augments organizational competitiveness).

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) causes not only severe illness but also detrimental effects associated with the lockdown measures. The present study aimed to evaluate reported lifestyle changes in a cohort of adults in Italy, including physical exercise, food choices, and psychological wellbeing, after two months of lockdown. METHODS: A web survey on social media (Facebook and LinkedIn) of 32 multiple-choice questions aiming to evaluate the impact of the national COVID-19 lockdown in a sample of Italian adults. RESULTS: We received 1378 complete responses (women 68.3%, mean age 39.5 ± 12.5 years). The percentage of participants reporting regular exercise decreased during lockdown (52 vs. 56.5%). The vast majority of people continued to consume the three traditional meals per day, but the consumption of meat, fish, and eggs significantly decreased. Women reported more frequent anxiety, sadness, fear, and feelings of insecurity than men. The factors predicting the worst outcome during the lockdown were being a woman, low education and income, gastrointestinal diseases. CONCLUSION: The lockdown has had a limited impact on food choices and physical exercise in Italian adults of our series, since most of them made an effort to improve their lifestyle. However, women with gastrointestinal diseases reported more frequent negative feelings and poor adaptation to the lockdown.

RESUMO

Abstract: The article describes some psychological peculiarities of the work with the emotional state of patients and one of the possible ways to correct it using art therapy - felt therapy, (the use of non-spun wool in an art therapy process). In the article are described the possibilities of this material and the effects of its use. The main tasks of the work are the formation of a conscious attitude to the disease, the recognition of the "secondary benefits" of having a "symptom", the actualization, awareness and replenishment of the spectrum of internal resources, the evolution of the ability to gain the access to them, as well as the integration, acceptance of the "symptom" and the suffering part of the personality, the acceptance of the diversity of one's own "I". The art therapeutic exercise described in the article also aims to reinforce a new positively colored creative experience, the formation of positive thinking. All of these helps the patient to feel a holistic personality, more harmonious and happy.

RESUMO

As COVID-19 solidifies its presence in everyday life, the interest in mental health is growing, resulting in the necessity of sentiment analysis. A smart mirror is suitable for encouraging mental comfort due to its approachability and scalability as an in-home AI device. From the aspect of natural language processing (NLP), sentiment analysis for Korean lacks an emotion dataset regarding everyday conversation. Its significant differences from English in terms of language structure make implementation challenging. The proposed smart mirror LUX provides Korean text sentiment analysis with the deep learning model, which examines GRU, LSTM, CNN, Bi-LSTM, and Bi-GRU networks. There are four emotional labels: anger, sadness, neutral, and happiness. For each emotion, there are three possible interactive responses: reciting wise sayings, playing music, and sympathizing. The implemented smart mirror also includes more-typical functions, such as a wake-up prompt, a weather reporting function, a calendar, a news reporting function, and a clock.

RESUMO

BACKGROUND: The novel coronavirus disease (COVID-19) is spreading rapidly, increasing the stress and challenges for healthcare professionals around the world. This study aims to discover the psychosocial, emotional and professional challenges faced by female healthcare professionals (HCPs) treating COVID-19 patients in Pakistan. METHODS: Using an empirical phenomenological methodology, semi-structured telephone-based qualitative interviews were conducted with 22 female HCPs who were providing their expertise for COVID-19 patients in tertiary-level hospitals in Lahore, Pakistan. Purposive sampling was used for recruitment. The interviews were conducted between 20 July and 20 August 2020. The interviews were analysed using thematic analysis. RESULTS: This study explored the psychosocial, emotional and professional challenges faced by female HCPs serving COVID-19 patients. Five themes were observed in the interviews: apprehension while treating COVID-19 patients; feelings towards COVID-19 patients; challenges as female HCPs and coping strategies; confidence in government, administration and self-reflection; and finally, future concerns and recommendations. Many of these themes have also been linked with cultural issues, making the results specific to Pakistan. CONCLUSIONS: During the COVID-19 pandemic, female frontline HCPs have faced immense psychosocial pressure, ranging from unsupportive family norms to an unwelcoming working environment and insensitive hospital administrations. Moreover, rumours among the general public, lack of proper training, missing incentives and improper system surveillance have increased the anxiety and stress among HCPs. Hence, legislators are advised to take appropriate actions countrywide in order to alleviate the still ongoing challenges and support female HCPs in their working environment.

RESUMO

BACKGROUND: Past studies have associated gratitude interventions with a host of positive outcomes. However, there is a dearth of research regarding the impact such interventions have on the academic motivation of university students, thought to be a primary determinant of academic achievement and overall satisfaction with school activities. Here, we examined the effects of a 2-week online gratitude journal intervention on the academic motivation of university students. METHODS: Eighty-four students were randomly assigned to either an active manipulation group (gratitude group) or a neutral control group. In the first 6 days of each week, participants in the gratitude group were asked to log in to the online system once a day and list up to five things they had felt grateful for. They were also requested to evaluate various aspects of their daily lives. Participants in the control group were only requested to perform the daily self-evaluations. Academic motivation was assessed using the Academic Motivation Scale (AMS), which conceptualizes motivation in academic settings as being composed by three different components, i.e., intrinsic motivation, extrinsic motivation and amotivation, the latter being associated with the perceived lack of contingency between actions and outcomes. Responses were collected 5 times: before group assignment (baseline), 1 week after the start of the intervention, immediately after the intervention, and at two follow-ups, 1 and 3 months after the intervention. RESULTS: Analysis using a self-determination index derived from the AMS components showed that participants who regularly engaged with the gratitude journal task displayed significant enhancements in academic motivation. Additional analysis revealed that the enhancements were driven by decreases in the levels of amotivation. Furthermore, follow-up data showed that there were no signs that such enhancements had receded 3 months after the end of the intervention. Improvements in academic motivation were not observed among participants in the control group. CONCLUSIONS: The current results provide evidence that gratitude interventions can positively impact the academic motivation of university students. More broadly, they show that the effects extend well beyond the realm of typically assessed measures of individual well-being, and can effectively regulate a fundamental component of goal-directed behavior such as motivation.

RESUMO

AIM: To assess schoolchildren's feelings and attitudes towards dentists and their potential impact on oral health. MATERIALS AND METHODS: 7902 schoolchildren (12 and 15 years old) attending public and private schools completed a questionnaire that assessed their feeling and attitude toward dentists. DMFT and CPI indices were used to assess dental caries and periodontal diseases respectively according to the World Health Organization method and criteria. RESULTS: 79.7% of all schoolchildren who participated in this study had been to the dentist. 24.7% reported that they are afraid of dental visits, pain being the main reason for this disturbing feeling (88, 2%). Of the children, 81.4% preferred a female dentist; 82.3% preferred a dentist with a colored coat and 80.3% favored a renovated dental facility. 91.1% of the children are irritated by the noises in the dental clinic. The mean DMFT and CPI scores were significantly higher in patients with dental fear, and in patients who never had a dental visit. CONCLUSION: Meeting patient's perceptions and preferences regarding their dentist may help to reduce the potential dental anxiety and thus ensure the delivery of a high-quality dental treatment leading to better oral health status. CLINICAL RELEVANCE: Patient perception about dentists is affected by a series of factors related to the dentist, the patient, and the dental clinic. Patients who experience the worst perceptions of dental professional tend not to seek dental care, which leads to a bad oral health status, hence the importance of further studies in this area to improve such perceptions, and promote attitudinal changes toward positive health-seeking behavior.

RESUMO

OBJECTIVES: This study was designed to explore the influence of social and family support system on the fertility pattern of human immunodeficiency virus (HIV)-infected women. TRIAL DESIGN: An interventional study including 70 participants. METHODS: HIV-infected female participants treated from January 2015 to January 2019 were selected, randomly divided into 2 groups, with 35cases in each group. The experimental group was given complete social and family support, whereas the control group was given basic treatment only. Changes in fertility rate, fertility number, and fertility interval were compared between the 2 groups. We also compared the changes in the quality of life (QOL), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS) of the 2 groups of participants. RESULTS: The fertility rate of the experimental group was 43.29%, and that of in the control group was 31.96%, and the childbearing age is mainly concentrated in the 20 to 29 years; the difference was statistically significant (P < .05). The mean number of births in the experimental group was (1.47 ±â€Š0.61), which was significantly higher than that of in the control group (0.63 ±â€Š0.22), and the difference was statistically significant (P < .05). The fertility interval of the experimental group was significantly lower than that of in the control group (2.65 ±â€Š1.34 vs 3.77 ±â€Š0.85), and the difference was statistically significant (P < .05). Before the intervention, there were no significant differences in the QOL scores, SAS, and SDS scores between the experimental group and the control group (P > 0.05). After intervention, the scores of QOL in the experimental group was significantly higher than those of in the control group (54.1 ±â€Š1.7 vs 41.2 ±â€Š2.5); the SAS and SDS scores of the experimental group were significantly lower than those of in the control group (39.3 ±â€Š4.2 vs 56.1 ±â€Š5.7; 32.2 ±â€Š6.7 vs 51.9 ±â€Š5.8), and the difference were statistically significant (P < .05). CONCLUSIONS: Social and family support for female participants infected with HIV can improve the fertility rate of women to some extent, increase the number of births and shorten the interval between births, and can help relief the women's anxiety, depression, and other emotional problems, which is worthy of extensive application and promotion in the society.

RESUMO

Recognition of the emotions demonstrated by human beings plays a crucial role in healthcare and human-machine interface. This paper reports an attempt to classify emotions using a spectral feature from facial electromyography (facial EMG) signals in the valence affective dimension. For this purpose, the facial EMG signals are obtained from the DEAP dataset. The signals are subjected to Short-Time Fourier Transform, and the peak frequency values are extracted from the signal in intervals of one second. Support vector machine (SVM) classifier is used for the classification of the features extracted. The extracted feature can classify the signals in the valence dimension with an accuracy of 61.37%. The proposed feature could be used as an added feature for emotion recognition, and this method of analysis could be extended to myoelectric control applications.

RESUMO

Emotions are essential for the intellectual ability of human beings defined by perception, concentration, and actions. Electroencephalogram (EEG) responses have been studied in different lobes of the brain for emotion recognition. An attempt has been made in this work to identify emotional states using time-domain features, and probabilistic random forest based decision fusion. The EEG signals are collected for this from an online public database. The prefrontal and frontal electrodes, namely Fp1, Fp2, F3, F4, and Fz are considered. Eleven features are extracted from each electrode, and subjected to a probabilistic random forest. The probabilities are employed to Dempster-Shafer's (D-S) based evidence theory for electrode selection using decision fusion. Results demonstrate that the method suggested is capable of classifying emotional states. The decision fusion based electrode selection appears to be most accurate (arousal F-measure = 77.9%) in classifying the emotional states. The combination of Fp2, F3, and F4 electrodes yields higher accuracy for characterizing arousal (65.1%) and valence (57.9%) dimension. Thus, the proposed method can be used to select the critical electrodes for the classification of emotions.
