Influencing factors of post-traumatic stress disorder in patients with acute myocardial infarction after percutaneous coronary intervention / 心血管康复医学杂志

Objective:To study influencing factors of post-traumatic stress disorder(PTSD)in patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods:According to score of PTSD checklist-civilian version(PCL-C),a total of 200 AMI patients undergoing PCI in our hospital were divid-ed into non-PTSD group(n=144,＜44 scores)and PTSD group(n=56,≥44 scores).General clinical data,scores of event related rumination inventory(ERRI),Eysenck personality questionnaire(EPQ)and social support rating scale(SSRS)were compared between two groups.Influencing factors of PTSD in AMI patients after PCI were analyzed.Results:There were 56 cases(28.00％)developing PTSD among the 200 AMI patients undergoing PCI.Compared with non-PTSD group,there were significant rise in age,percentage of hypertension,scores of in-vasive rumination of ERRI and neuroticism of EPQ,and significant reductions in percentage of living in town,scores of active rumination and internal & external of ERRI and SSRS in PTSD group(P＜0.05 or＜0.01).Multiva-riate Logistic regression analysis indicated that age and score of SSRS were independent protective factors for PTSD in AMI patients after PCI(OR=0.885,0.602,P=0.024,0.035),and scores of invasive rumination and neuroti-cism were independent risk factors for it(OR=2.986,3.360,P=0.032,0.025).Conclusion:Incidence rate of PTSD is higher in patients with acute myocardial infarction after PCI.Age,social support,scores of neuroticism and invasive rumination were influencing factors of PTSD in patients with acute myocardial infarction after PCI.

Association between patient safety culture and professional quality of life among nursing professionals / Asociación entre la cultura de seguridad del paciente y la calidad de vida profesional de los profesionales de enfermería / Associação entre cultura de segurança do paciente e qualidade de vida profissional de trabalhadores de enfermagem

ABSTRACT Objective: To analyze the association between patient safety culture and professional quality of life in nursing professionals. Method: Correlational study carried out in a hospital in Salvador, Bahia, Brazil, with 180 participants. The data were collected through the Hospital Survey on Patient Safety Culture and Professional Quality of Life Scale and analyzed with correlation tests. Results: The use of the Quality of Professional Life model, which encompasses Compassion Satisfaction, Burnout and Traumatic Stress, showed that a better assessment of the safety culture was negatively associated with Burnout. Regarding the dimensions of culture, better evaluations of the general perception of safety, teamwork and staffing were negatively associated with Burnout and Traumatic Stress. Higher Burnout was negatively associated with better handoffs and greater Traumatic Stress was positively associated with error communication. Conclusion: Higher levels of Burnout were associated with worse perception of safety culture and worse teamwork evaluations; staffing and general perception of safety were associated to a higher level of Burnout and Traumatic Stress, which emphasizes the importance of investment in these areas.

Relationship of PTSD after hypertensive intracerebral hemorrhage and rs806377 polymorphism of CNR1 gene in elderly patients / 中华老年心脑血管病杂志

Objective To construct a risk prediction model of post-traumatic stress disorder(PTSD)after hypertensive intracerebral hemorrhage in elderly patients and analyze the correla-tion of PTSD with rs806377 polymorphism of cannabinoid receptor 1(CNR1)gene.Methods A total of 215 elderly patients with hypertensive cerebral hemorrhage admitted to the Department of Neurology of Geriatric Hospital of Hainan and Department of Neurosurgery of the First Affiliated Hospital of Hainan Medical University from January 2020 to August 2022 were enrolled in this study.According to the results of PTSD scale(scoring＞50 or 0～50)after surgical treatment,they were divided into PTSD group(43 cases)and non-PTSD group(172 cases).The rs806377 polymorphism of CNR1 gene was detected in both groups by gene sequencing.Univariate and mul-tivariate logistic regression analyses were used to analyze the susceptibility to PTSD among the elderly after hypertensive intracerebral hemorrhage.Another 103 elderly patients with hyperten-sive intracerebral hemorrhage during the same period were also subjected and served as verifica-tion set.A prediction model was constructed.Results There were significant differences in age,family annual income,blood loss amount,psychological resilience score and social support score between the PTSD group and non-PTSD group(P＜0.05,P＜0.01).The PTSD group had obvi-ously larger proportion of TT genotype carriers and higher T allele frequency than the non-PTSD group(P＜0.05,P＜0.01).Logistic regression analysis showed that age(OR=2.020,95％CI:1.115-3.658),family annual income(OR=1.799,95％CI:1.232-2.626),blood loss(OR=1.507,95％CI:1.243-1.826),psychological resilience score(OR=2.059,95％CI:1.068-3.969),social support score(OR=1.664,95％CI:1.122-2.467),rs806377 TT genotype(OR=1.861,95％CI:1.485-2.331)and rs806377 T allele(OR=3.777,95％CI:2.049-6.962)were the influencing fac-tors of postoperative PTSD in these patients(P＜0.05,P＜0.01).ROC curve analysis indicated that the sensitivity was 69.57％,the specificity was 71.25％,and the AUC value was 0.762(95％CI:0.708-0.813)in the verification group,indicating a certain accuracy of our model.Conclusion CNR1 gene rs806377 locus polymorphism is an influencing factor for PTSD susceptibility,and rs806377 TT genotype and rs806377 T allele can predict PTSD in elderly patients after hyperten-sive intracerebral hemorrhage.

Interaction between the impact of the Coronavirus disease 2019 pandemic and demographic characteristics on sexual/erectile dysfunction in Latin America: cross-sectional study

ABSTRACT Aim: Our objective was to investigate whether there is an interaction between the COVID-19 pandemic, demographic characteristics and erectile/sexual (E/S) function in individuals from Latin America. Materials and Methods: Cross-sectional study which included Latin American individuals over 18 years old, recruited through social media and interviewed between July and August 2020 by online surveys (Google Forms) in Portuguese and Spanish languages. The E/S function was evaluated through the following questionnaires: Simplified International Index of Erectile Function (IIEF-5) and Female Sexual Function Index (FSFI); while post-traumatic stress disorder (PTSD) triggered by the COVID-19 pandemic was assessed through the Impact of Event Scale Revised (IES-R). The data was analyzed by T Student, bivariate and multivariate logistic regression, with significance determined by the Wald test (p<0.05), using the R software v4.0. Results: Out of the 2016 individuals that responded to the survey, 1986 were included and 743 of them presented E/S dysfunction. PTSD occurrence was greater among people with E/S dysfunction when compared to those without E/S dysfunction, in the total score (males: IES-R=26.54[±19.17] and females: IES-R=35.92[±19.25]) and also in the three domains. It was found that those who do not live with a partner were 74% more likely to have E/S dysfunction, but living with a partner during the pandemic had a greater impact on E/S function. Conclusion: A negative interaction between the impact of the COVID-19 pandemic and erectile/sexual function of the Latin American population was observed, with greater implications among the individuals who live with their partners.

Objective:To explore the effects of fast-track surgery (FTS) combined with acupuncture at Neiguan acupoint on stress indicators and recovery quality in patients during anesthesia of craniocerebral surgery.Methods:According to block randomization method, 120 patients with craniocerebral trauma meeting inclusion criteria in the hospital were divided into three groups between January 2018 and December 2020, 40 in each group. The control group was given routine awakening intervention, intervention 1 group was given routine awakening intervention and acupuncture at Neiguan acupoint, and intervention 2 group was given FTS and treatment of intervention 1 group. At 10 min after entering the room, immediately after tracheal intubation and immediately after extubation, level of serum cortisol (COR) was detected by electrochemical luminescence apparatus. The level of serum dopamine was detected by ELISA. The blood pressure and heart rates were recorded. The recovery quality during anesthesia was compared, including recovery time, recovery time of spontaneous breathing, extubation time and recovery time of orientation. The cognitive function of patients was evaluated by Neurobehavioral Cognitive Status Examination (NSCE). The incidence of intestinal paralysis, nausea and vomiting, and hospitalization time were observed and recorded during treatment.Results:Immediately after tracheal intubation and extubation, systolic blood pressure in intervention 2 group, intervention 1 group and control group were significantly decreased ( F=12.03, 13.96), levels of serum COR ( F=91.40, 53.76), and dopamine ( F=29.72, 69.39) were significantly decreased ( P<0.01). The recovery time of orientation during anesthesia [(39.09±3.12)min vs. (41.57±3.54)min, (43.84±3.28)min, F=34.65] in intervention 2 group was significantly shorter than that of the intervention 1 group and control group ( P<0.01), and hospitalization time [(9.36±1.78)d vs. (10.92±1.81)d, (12.10±1.95)d, F=1.44] was significantly shorter than that of the intervention 1 group and control group ( P<0.05). Conclusion:The FTS combined with acupuncture at Neiguan acupoint can reduce stress level during anesthesia, improve recovery quality and relieve postoperative cognitive dysfunction in patients undergoing craniocerebral surgery.

Association between stress and lower urinary tract symptoms in children and adolescents

ABSTRACT Introduction: Lower urinary tract dysfunction (LUTD) is a common clinical condition. Emotional and behavioral issues are increasing among children and adolescents, with stress indicating difficulties in personal and social functioning. This study evaluated whether urinary tract symptoms (LUTS) is associated with stress. Materials and Methods: A cross-sectional, analytical study with 6-14-year-old patients with LUTS and no anatomical/neurogenic urinary tract abnormalities was conducted using the Dysfunctional Voiding Scoring System, a psychological assessment and the Child Stress Scale. The overall stress score was analyzed in relation to the psychological assessment data. Answers to the seven specific DVSS urinary questions were compared with those for the four Child Stress Scale domains. Univariate and multivariate analyses were performed. The chi-square test and Pearson's correlation were used to determine associations. Significance was defined as p <0.05. Results: Most children were male (56%). Mean age was 9.0±2.25 years. Stress was detected in 20 out of 98 patients (20.4%; 95% CI: 13-30%). Of these, 90% were born from unplanned pregnancies and 67% were upset about their disorder. All the Child Stress Scale domains were significantly associated with urinary dysfunction, with dysuria being significantly associated with all four domains. In the multivariate analysis, dysuria was the only symptom that remained associated with stress. Associations with stress strengthened as the frequency of dysuria increased: physical reactions (p <0.01), emotional reactions (p <0.05), psychological reactions with a depressive component (p <0.01) and psychophysiological reactions (p <0.05). Conclusion: Stress levels are higher in children and adolescents with LUTS who have more severe symptoms. Dysuria was the symptom most associated with stress, both in the physical reactions domain, in the psychological reactions domains with or without a depressive component and in the psychophysiological reactions domain.

The relationship between traumatic event exposure rate and major depressive disorder prevalence in community population in Tianjin / 天津医药

Objective To investigate the prevalence of traumatic event exposure and its relationship with major depressive disorder (MDD) in community population in Tianjin. Methods A multi-stage cluster random sampling method was used for the general health questionnaire (GHQ-12) in the population aged above 18 in 15538 families of 18 counties in Tianjin city. Among the 11748 subjects who completed the survey, they were divided into the high-risk group (100%), medium risk group (40%) and low risk group (10%) according to the risk level of mental disorders. Finally, 4438 residents were interviewed with the diagnostic and statistical manual of mental disorders Fourth Edition (DSM-Ⅳ) axisⅠdiagnostic clinical interview version (SCID-Ⅰ/P). The prevalence of respondents exposed to traumatic events and MDD was calculated. Logistic regression analysis was applied to obtain the risk factors of MDD. Results A total of 469 people experienced traumatic events in 4438 subjects, and the adjusted total exposure rate was 10.3%. Seventy-six people suffered from MDD in 469 cases with traumatic events, and the adjusted total exposure rate was 6.7%. The prevalence of MDD was 3.3% in people with no traumatic events. Logistic regression analysis showed that female (OR=1.77,95%CI:1.27-2.46), widowed/divorced and experienced a traumatic event (OR=2.21,95%CI:1.46-3.34) were the risk factors of MDD. Conclusion The total exposure rate of traumatic events is 10.3% in community residents in Tianjin, and the prevalence of MDD is related with the traumatic event exposure. It is suggested that the whole society should mobilize and participate extensively, and pay more attention to the psychological health problems of high risk population.

Effect of stress-induced hyperglycemia on myocardial perfusion and prognosis in elderly patients ;with acute myocardial infarction undergoing primary percutaneous coronary intervention / 中国医师进修杂志

Objective To investigate the effect of stress-induced hyperglycemia (SHG) on myocardial perfusion and clinical prognosis in elderly patients with acute myocardial infarction (AMI) who underwent primary percutaneous coronary intervention (PCI). Methods In this study, 459 elderly patients with first-time occurrence of acute ST-elevation myocardial infarction (STEMI) who underwent primary PCI within 12 h from January 2012 to January 2015 were enrolled and followed up. All patients were divided into three groups according to serum glucose (SG) on admission: normal group (SG11.1 mmol/L, 142 patients). Myocardial perfusion indexes, including ST segment resolution (STR), TIMI myocardial perfusion grade (TMPG), peak value of creatine kinase (CK)-MB, left ventricular ejection (LVEF), and major adverse cardiac events (MACE) of patients in three groups were measured and compared after emergency PCI. Results The blood glucose levels were increased, ST-elevation 2 h after PCI were well declined, the percentages of patients with TMPG 2-3 were decreased and peak values of CK-MB were increased in the three groups (P<0.05). After 12 months of follow-up, Kaplan-Meier survival analysis showed that cumulative non-events survival rates in three groups had significantly different: 89.2% (132/148) vs. 85.8% (145/169) and 76.1% (108/142), P<0.05. Multivariate Cox regression analysis showed that SHG was the independent predictor for the occurrence of MACE in patients undergoing PCI after adjusting for age and gender (P<0.05). Conclusions SHG in elderly patients with STEMI can decrease myocardial perfusion level after primary PCI, which will lead to high incidence of MACE.

Expressions of hypothalamus BDNF and GAP-43 and their relation with behavior changes in response to restraint stress in rats / 中华创伤杂志

Objective To investigate the expressions of brain-derived nerve growth factor (BDNF) and growth-associated protein 43 (GAP-43) in the hypothalamus of rats inflicted with restraint stress and their relationship with behavioral changes.Methods Forty male SD rats were divided into control group,restraint stress 7-day group,restraint stress 14-day group,restraint stress 21-day group according to the random number table,with 10 rats per group.Behavior changes were observed by open-field test,serum levels of corticotrophin releasing hormone (CRH) by enzyme-linked immunosorbent assay,and expressions of BDNF and GAP-43 in the hypothalamus by western blotting.Results Restraint stress 7-day group exhibited increases in spanning lattice times (50.0 ± 7.0),standing times (11.4 ± 2.1)and modification times (11.2 ± 2.7) compared with all other groups (P ＜ 0.05).Restraint stress 14-day group and restraint stress 21-day group showed significant decreases in spanning lattice times (35.5 ±7.5,29.4 ± 6.8),standing times (7.8 ± 4.9,5.6 ± 3.9) and modification times (6.7 ± 2.9,4.4 ±2.6) compared with control group (42.6 ± 5.4,8.9 ± 4.3,and 7.9 ± 3.0) (P ＜ 0.05).Restraint 14-day and 21-day groups showed significant increases in serum CRH level [(750.73 ± 123.68) pg/ml and (793.06 ± 115.84)pg/ml] compared with that in restraint stress 7-day group [(500.48 ± 88.71)pg/ml,P ＜0.05],but all were lower than (336.72 ±45.34) pg/ml in control group (P ＜0.05).Levels of BDNF and GAP-43 in the hypothalamus were the lowest in control group (0.672 ± 0.185 and 0.694 ±0.253).However,restraint stress increased the expressions of BDNF and GAP-43 in the hypothalamus,with the highest level in restraint stress 21-day group (1.357 ± 0.524 and 1.486 ± 0.679) (P ＜ 0.05).Conclusion Restraim stress can up-regulate BDNF and GAP-43 proteins in the hypothalamus,and lead to plasticity changes that may relate to stress-related behavior.

OBJETIVO: Identificar a incidência de transtorno de estresse pós-traumático (TEPT) em pacientes submetidos à ventilação mecânica (VM) e analisar a sua relação com variáveis clínicas, demográficas e presença de recordações referentes à unidade de terapia intensiva (UTI). MÉTODO: Estudo prospectivo longitudinal realizado durante o período de um ano na UTI de um hospital-escola. A avaliação ocorreu três meses após a alta da UTI durante consulta ambulatorial. Os sujeitos foram avaliados utilizando-se um instrumento para avaliar memórias de UTI (IAM-TI) e o Impact of Event Scale-Revised (IES-R), para avaliar o TEPT. RESULTADOS: Do total de respondentes, 68,8% eram do sexo masculino, a idade variou entre 18 e 79 anos, com média de 43,5 anos ± 17,1. Quanto à avaliação dos pacientes, 14,5% apresentaram sintomas de TEPT, quando utilizado um ponto de corte > 20 pontos. Para uma melhor precisão diagnóstica, foi utilizado também o ponto de corte ≥ 33 pontos e, nesse caso, sete pacientes (5,1%) apresentaram o transtorno. CONCLUSÃO: Poucos pacientes preencheram todos os critérios para o diagnóstico de TEPT, indicando que a grande maioria deles apresentou apenas sintomatologia relacionada ao TEPT.

OBJECTIVE: Identify the incidence of post-traumatic stress disorder (PTSD), in patients submitted to MV and analyze its relation with clinical and demographical variables, and with the presence of memories regarding intensive care unit (ICU). METHOD: It is a longitudinal prospective study, carried out in one year at an ICU of a university hospital. Evaluation occurred three months after ICU discharge during patients follow up at the ambulatory. Subjects were evaluated using the ICU memories (ICU-AMI) and the Impact of Event Scale-Revised (IES-R) instruments. RESULTS: From the total of subjects, 68.8% were male from 18 to 79 years of age, 43.5 years old average ± 17.1. From the evaluated patients, 14.5% presented symptoms of PTSD when a cut-off score > 20 was used. For a diagnostic accuracy a ≥ 33 cut-off score was also used, and in this case, only seven patients (5.1%) showed signs of PTSD. CONCLUSION: A few patients met the criteria for the PTSD diagnosis indicating that the great majority of patients admitted at ICU show only symptomatology related to PTSD.

Serum levels of brain-derived neurotrophic factor in acute and posttraumatic stress disorder: a case report study / Nível sérico do fator neurotrófico derivado do cérebro no transtorno de estresse agudo e no transtorno de estresse pós-traumático: relato de casos

OBJECTIVE: The aim of this study was to evaluate brain-derived neurotrophic factor levels in two patients, one with posttraumatic stress disorder and one with acute stress disorder, before and after treatment, and to compare those levels to those of healthy controls. METHOD: Brain-derived neurotrophic factor level, Davidson Trauma Scale, Beck Depression Inventory, Global Assessment of Functioning, and Clinical Global Impression were assessed before and after 6 weeks of treatment. RESULTS: Brain-derived neurotrophic factor levels were higher in patients than in matched controls before treatment. After 6 weeks, there was a reduction in symptoms and an improvement in functioning in both cases. At the same time, brain-derived neurotrophic factor levels decreased after treatment, even in case 2, treated with psychotherapy only. CONCLUSIONS: These results suggest that serum levels of brain-derived neurotrophic factor, as opposed to what has been described in mood disorders, are increased in posttraumatic stress disorder as well as in acute stress disorder.

OBJETIVO: O objetivo do estudo foi avaliar os níveis séricos do fator neurotrófico derivado do cérebro em um paciente com transtorno de estresse pós-traumático e em um paciente com transtorno de estresse agudo antes e após o tratamento, comparando esses níveis aos de controles saudáveis. MÉTODO: Os níveis do fator neurotrófico derivado do cérebro, a Escala Davidson de Trauma, o Inventário de Depressão de Beck, a Avaliação do Funcionamento Global e a Impressão Clínica Global foram medidos antes e após seis semanas de tratamento. RESULTADOS: Os níveis de fator neurotrófico derivado do cérebro foram maiores nos pacientes, quando comparados aos controles, antes do tratamento. Depois de seis semanas houve redução dos sintomas e melhora do funcionamento nos dois casos. Ao mesmo tempo, houve redução dos níveis de fator neurotrófico derivado do cérebro, mesmo no caso 2, tratado exclusivamente com psicoterapia. CONCLUSÕES: Esses resultados sugerem que o fator neurotrófico derivado do cérebro está aumentado tanto no transtorno de estresse pós-traumático quanto no transtorno de estresse agudo, de forma oposta às alterações até então descritas nos transtornos do humor.

Effects of cannabinoid 1 receptor on regulation of visceral sensitivity in rats with acute restraint stress / 中华消化杂志

Objective To investigate the effects of cannabinoid 1 receptor (CB1R) on regulating visceral sensitivity in rats with acute partial restraint stress. Methods Thirty Sprague-Dawley rats were divided into blank control (sham stress), acute stress and CB1R groups with 10 each. The frequency of discharge of electromyogram (EMG) was recorded at the 1st, 2nd, 5th and 8th day to evaluate the visceral sensitivity to colorectal distension (CRD) in rats. The expression of the CB1R mRNA was determined by means of RT-PCR at day 8. Results There was no significant difference in baseline discharge frequency among three groups at the 1st day. But the discharge frequencies corresponding to CRD at 40,60,80 mm Hg at the 2nd day were significantly lower in CB1R group [(22.37±1.49)/min, (42.24±3.03)/min and (69.09±5.54)/min, respectively] than in acute stress group [(39.71±1.84)/min, (84.45±8.85)/min and (112.56±11.66)/min, respectively, P<0.05)]. The discharge frequencies corresponding to CRD at 40, 60,80 mm Hg in acute stress group [(104.12±6.77)/min, (158.07±18.68)/min, (193.58±25.69)/min,respectively] showed a significant elevation at the 5th day in comparison with blank control group[(36.33±5.42)/min, (74.07±8.25)/min, (102.94±7.95)/min, respectively, P<0.05] or CB1R group [(74.66±6.44)/min,(140.10±4.68)/min and (160.39±5.60)/min,respectively, P<0.05]. However, at the 8th day after stress, there was no significant difference in discharge frequency among three groups. The expressions of CB1R mRNA in ileocecal junction, proximal colonic and distal colonic tissues were significantly higher in acute stress group (2.53±0.52, 2.29±0.42, 2.54±0.29 respectively) than in blank control group(0.56±0.15, 0. 73±0.12, 0.82±0.09, respectively, P<0.05). There was no effect of CB1R agonist on CB1R mRNA expression in rats. Conclusion The visceral sensitivity in rats induced by stress can trigger the accommodation of endogenous cannabinoid system that plays an important role in modulation of visceral sensitivity.
