Childhood traumatic events and the dopaminergic theory of psychosis: A mini-review of studies investigating gene – environment interactions

There is great body of evidence showing a relationship between childhood adversity and psychosis onset. Genetic factors moderate the association between childhood adversity and psychosis risk potentially by influencing biological and/or psychological reaction following exposure to adversity. In this review, we discuss studies identifying the specific genetic variants known to affect dopamine levels involved in this interaction. Our review shows that the catechol-O-methyltransferase (COMT), dopamine D2 receptor (DRD2), AKT1 gene play a key role in mediating the relationship between childhood adversity and development of psychosis. We have also found conflicting findings on the impact of dopamine genes on the relationship between childhood adversity and development of psychosis, suggesting that other genetic and environmental factors should be taken into account. We here discuss the implications of our findings and future directions.

The role of the psychoemotional stress during gestation in the development of obstetrical and perinatal patology

The complex investigation of the perinatal pathology at acute and c/1,1-onic psyclioemotliional stress dunng gestation has been perf 01 wed. Jt was sliown (by tlie metliod of the retrospective analyses) the inaease in the relat-ive 1-isf of tlie premature delivery (1,4-8,0), severe and mild gestosis (3,0-10,0), placental pathology (2,2-3,3 ), anomalies of delivery (2,0-7,0 ), obstetlical Blending (2,0- 2,8 ), late delivery (2,0-7,0) dunng the acute stress. The relationship between tlie pelinatal patology and gestation term was shown dunng the acute stress. Dm'ing- i-lie clironic stress tlie frequency and seventy of pennatal patliology is dependent upon the type of psyclioemotional reaction on the st-ress. The seventy of patliofog-y is more prominent at decompensated type of psychological reaction t-lian at subcompensated type. Tlie newbom infants of motlias witli psyclioemotional stress recuired long rehabilitation in 39,2-50,0% cases.

When Motivated Responses to Threat Backfire: Risky Socializing During the COVID-19 Health Crisis

This research examined the relationship between psychological processes that help individuals cope with challenging circumstances and their failure to act to reduce the likelihood and severity of the challenge itself. In two cross-sectional studies of U.S. residents ( N = 621) conducted during the COVID-19 pandemic, individuals’ motivated responses to threat predicted their noncompliance with directives prohibiting risky socializing: Those who perceived the disease to be a threat to their health were more likely to engage in risky socializing if they avoided information about the pandemic or they exhibited a dispositional tendency to join with other people when stressed. Several alternative causal sequences can account for these findings, but one suggests that the risky socializing during the COVID-19 pandemic was due, in part, to people’s psychological reaction to threat; as people responded to minimize their distress, they inadvertently increased their risk of contracting the illness.

Management of complicated crown root fracture using pizeo surgery, fiber post and fragment reattachment: A case report

A common type of fracture involving tooth is complicated crown root fracture of anterior teeth. The reattachment of the coronal fragment to the remaining tooth will provide better and long-lasting aesthetics, improved function and a positive psychological reaction. It is a simple and less difficult procedure if the original tooth fragments are retained after fracture. This paper reports about a case of complicated crown root fracture that was treated successfully using broken fragment adhesive reattachment and post placement.

Gender Comparison of Psychological Reaction Between Breast Cancer Survivors and Their Spouses

Background: Scant evidence exists among the different psychological issues between patients with breast cancer and their spouses. The objective of our study was to develop the measuring instrument testing psychological reaction and compare the difference in psychological reaction between patients with breast cancer and their spouses during the period of diagnosis and treatment.Method: The semi-structured interview guideline was guided by the psychological stress model. In-depth interviews were conducted among patients with breast cancer and their spouses. Qualitative data was used to establish the item pool for the psychological reaction. Delphi method was used for item modifications. The items were conducted to find common factors through exploration factor analysis. Comparing the differences of common factors through t-test between patients with breast cancer and their spouses.Results: Five couples were interviewed directed by the semi-structured interview guideline. About 38 items were reserved to formulate the questionnaire through the Delphi method. A total of 391 respondents (216 patients and 175 spouses) were recruited to complete the questionnaire. Two common structures were found through exploration factor analysis, which was named as reaction to role and body image change and negative coping reaction. The t-test found that the dimension of reaction to role and body image change (95% CI = 2.34–5.01, p < 0.001) reflects the difference between patients with breast cancer and their spouses.Conclusion: The reactions to role and body image change between patients with breast cancer and their spouses are different during the period of diagnosis and treatment. Clinical workers should pay attention to the different reactions and help couples deal with breast cancer smoothly.

Psychological reaction to Covid-19 of Italian patients with IBD

Background Patients with inflammatory bowel disease (IBD) may be particularly vulnerable to the effects of the novel coronavirus (Covid-19) on disease management and psychological status. This study explored psychological reactions to the Covid-19 emergency and IBD disease management in a sample of Italian patients. Methods An online questionnaire was designed to assess general concerns, psychological reaction, disease management, socio-demographics, and clinical information with validated scales and ad hoc items. A non-probabilistic purposive sample was selected, comprised patients with IBD who belonged to the Italian Association for patients with IBD (AMICI Onlus) completed the questionnaire in April 2020. Data obtained were analyzed using descriptive statistics, student’s T-test for independent groups, and one-way ANOVA (Analysis of Variance). Results One thousand fourteen eligible questionnaires were analyzed. Italian patients with IBD appeared to be very worried about the Covid-19 emergency (60.7%) and concerned about the risks of infection (59%). Half of the sample reported medium to high-perceived stress, and 74% had low-medium coping self-efficacy levels. One third was in a state of psychological arousal. Twenty-nine percent of patients had canceled hospital appointments for fear of contracting the virus. The majority of responders believed that belonging to the Italian Association for Patients with IBD - AMICI Onlus - is useful. Conclusions The results revealed that this sample of Italian patients with IBD lived with medium level of stress and with inadequate coping self-efficacy regarding disease management. Accordingly, Covid-19 may affect self-management behaviors. Therefore, national and regional associations for patients with IBD, should largely support these patients in this emergency.

Development and psychometric validity of the perioperative anxiety scale-7 (PAS-7)

Background Preoperative anxiety is a common psychological reaction in perioperative patients. The absence of a valid measurement tool hinders the evaluation of interventions to treat preoperative anxiety in China. This study aims to develop the Perioperative Anxiety Scale-7 (PAS-7) and test its reliability, validity, and cut-off value. Methods A total of 280 patients over 16 years old (M = 55.1, SD = 14.3) who were undergoing elective surgery were recruited to complete the PAS-7 and the Generalized Anxiety Disorder-7 scale (GAD-7) one day before surgery. Results The PAS-7 included seven items divided into two dimensions: mental anxiety and somatic anxiety. These two dimensions could explain 74.294% of the population variance. The internal consistency of each dimension ranged from 0.761–0.933. The confirmatory factor analysis showed that the model fit of the scale was good (χ2= 34.798, df = 13, χ2/df = 2.677, CFI = 0.949, TLI = 0.918, SRMR = 0.057, RMSEA = 0.115). The correlations between the GAD-7 and each dimension and the scale’s total score were significant (0.711–0.789). A cut-off score of 8, maximizing the Youden Index, yielded a sensitivity of 75% and a specificity of 84.6% (95% CI: 0.88 ~ 0.97). Conclusions The PAS-7 had good reliability and validity and could be used as an effective tool to evaluate preoperative anxiety.
