- Psychiatric Disorder and Incessant Tachyarrhythmia in a Child. [JOURNAL ARTICLE]
- Case Rep Pediatr 2013.:572301.
The case of a 14-year-old female with ectopic atrial tachycardia who had been followed for a history of anxiety and depression is presented. The patient was admitted to the intensive care unit after she attempted suicide, at which point there was electrocardiographic evidence of the atrial arrhythmia. During subsequent invasive electrophysiology study, a focus near the tricuspid annulus was localized and targeted for ablation, followed by resolution of the psychiatric symptoms. The case highlights the overlap between psychiatric complaints and true cardiac arrhythmia. A review of the literature is presented, with a special emphasis on distinguishing these two entities as well as a synopsis of this uncommon arrhythmia in the pediatric population.
- Impact of Self-Watching Double J Stent Insertion on Pain Experience of Male Patients: A Randomized Control Study Using Visual Analog Scale. [JOURNAL ARTICLE]
- ISRN Urol 2013.:523625.
Objective.To confirm safety and feasibility of double J stent insertion under local anesthesia and to assess the effect of detailed explanation and observing double J stent insertion on pain experience of male patients. Material and Methods. Eighty consenting males, randomized and divided prospectively into group A, who were allowed to observe DJ stent insertion, and group B, were not observed. All DJ stent insertions were done by senior urologist in operating urology room with or without fluoroscopy guidance. At the end of the procedure the vital signs and duration of the procedure were documented and patients were asked to fill unmarked 100 mm visual analogue pain scale (VAS) as soon as the surgeon leaves operating room.
Results.Mean age of entire study group was 38.8 years; the majority of the patients had DJ stent insertion for obstructed ureteric stone, with uneventful outcomes. Postprocedural systolic blood pressure and mean pain using VAS showed statistically significant difference between groups A and B.
Conclusion.DJ stent insertion under local anesthesia is a safe and feasible procedure. We recommended self-watching and detailed explanation to patients who underwent DJ stent insertion to reduce the pain and anxiety associated with the procedure.
- The Value of Peer Learning in Undergraduate Nursing Education: A Systematic Review. [JOURNAL ARTICLE]
- ISRN Nurs 2013.:930901.
The study examined various methods of peer learning and their effectiveness in undergraduate nursing education. Using a specifically developed search strategy, healthcare databases were systematically searched for peer-reviewed articles, with studies involving peer learning and students in undergraduate general nursing courses (in both clinical and theoretical settings) being included. The studies were published in English between 2001 and 2010. Both study selection and quality analysis were undertaken independently by two researchers using published guidelines and data was thematically analyzed to answer the research questions. Eighteen studies comprising various research methods were included. The variety of terms used for peer learning and variations between study designs and assessment measures affected the reliability of the study. The outcome measures showing improvement in either an objective effect or subjective assessment were considered a positive result with sixteen studies demonstrating positive aspects to peer learning including increased confidence, competence, and a decrease in anxiety. We conclude that peer learning is a rapidly developing aspect of nursing education which has been shown to develop students' skills in communication, critical thinking, and self-confidence. Peer learning was shown to be as effective as the conventional classroom lecture method in teaching undergraduate nursing students.
- Association between Chronic Prostatitis/Chronic Pelvic Pain Syndrome and Anxiety Disorder: A Population-Based Study. [JOURNAL ARTICLE]
- PLoS One 2013; 8(5):e64630.
this case-control study utilized a population-based dataset to examine the association of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with prior anxiety disorder (AD) by comparing the risk of prior AD between subjects with CP/CPPS and matched controls in Taiwan.We study used data sourced from the Taiwan Longitudinal Health Insurance Database. The cases comprised 8,088 subjects with CP/CPPS and 24,264 randomly matched subjects as controls. We used a conditional logistic regression to calculate the odds ratio (OR) for having been previously diagnosed with AD between subjects with and without CP/CPPS.Of the 24,264 sampled subjects, 2309 (7.1%) had received an AD diagnosis before the index date; AD was found in 930 (11.5%) cases and 1379 (5.7%) controls (p<0.001). The conditional logistic regression analysis revealed that compared to controls, the OR for prior AD among cases was 2.10 (95% CI = 1.92∼2.29, p<0.001) after adjusting for diabetes, hypertension, hyperlipidemia, and sexually transmitted diseases. Our results show that CP/CPPS was consistently and significantly associated with prior AD in all age groups (18∼39, 40∼59, and >59 years). In particular, subjects aged 40∼59 years had the highest adjusted OR (of 2.53) for prior AD among cases compared to controls.We concluded that CP/CPPS is associated with previously diagnosed AD. Urologists should be alert for the association between CP/CPPS and AD in subjects suffering from AD.
- Different Patterns of Respiration in Rat Lines Selectively Bred for High or Low Anxiety. [JOURNAL ARTICLE]
- PLoS One 2013; 8(5):e64519.
In humans, there is unequivocal evidence of an association between anxiety states and altered respiratory function. Despite this, the link between anxiety and respiration has been poorly evaluated in experimental animals. The primary objective of the present study was to investigate the hypothesis that genetic lines of rats that differ largely in their anxiety level would display matching alterations in respiration. To reach this goal, respiration was recorded in high-anxiety behavior (HAB, n = 10) and low-anxiety behavior (LAB, n = 10) male rats using whole-body plethysmography. In resting state, respiratory rate was higher in HABs (85±2 cycles per minute, cpm) than LABs (67±2 cpm, p<0.05). During initial testing into the plethysmograph and during a restraint test, HAB rats spent less time at high-frequency sniffing compared to LAB rats. In addition, HAB rats did not habituate in terms of respiratory response to repetitive acoustic stressful stimuli. Finally, HAB rats exhibited a larger incidence of sighs during free exploration of the plethysmograph and under stress conditions. We conclude that: i) HAB rats showed respiratory changes (elevated resting respiratory rate, reduced sniffing in novel environment, increased incidence of sighs, and no habituation of the respiratory response to repetitive stimuli) that resemble those observed in anxious and panic patients, and ii) respiratory patterns may represent a promising way for assessing anxiety states in preclinical studies.
- Cognitive Bias Modification versus CBT in Reducing Adolescent Social Anxiety: A Randomized Controlled Trial. [JOURNAL ARTICLE]
- PLoS One 2013; 8(5):e64355.
Social anxiety is a common mental disorder among adolescents and is associated with detrimental long term outcomes. Therefore, this study investigated the efficacy of two possible early interventions for adolescent social anxiety and test anxiety. An internet-based cognitive bias modification (CBM; n = 86) was compared to a school-based cognitive behavioral group training (CBT; n = 84) and a control group (n = 70) in reducing symptoms of social and test anxiety in high socially and/or test anxious adolescents aged 13-15 years. Participants (n = 240) were randomized at school level over the three conditions. CBM consisted of a 20-session at home internet-delivered training; CBT was a 10-session at school group training with homework assignments; the control group received no training. Participants were assessed before and after the intervention and at 6 and 12 month follow-up. At 6 month follow-up CBT resulted in lower social anxiety than the control condition, while for CBM, this effect was only trend-significant. At 12 month follow-up this initial benefit was no longer present. Test anxiety decreased more in the CBT condition relative to the control condition in both short and long term. Interestingly, in the long term, participants in the CBM condition improved more with regard to automatic threat-related associations than both other conditions. The results indicate that the interventions resulted in a faster decline of social anxiety symptoms, whereas the eventual end point of social anxiety was not affected. Test anxiety was influenced in the long term by the CBT intervention, and CBM lead to increased positive automatic threat-related associations.TrialRegister.nl NTR965.
- Chronic Unpredictable Stress (CUS)-Induced Anxiety and Related Mood Disorders in a Zebrafish Model: Altered Brain Proteome Profile Implicates Mitochondrial Dysfunction. [JOURNAL ARTICLE]
- PLoS One 2013; 8(5):e63302.
Anxiety and depression are major chronic mood disorders, and the etiopathology for each appears to be repeated exposure to diverse unpredictable stress factors. Most of the studies on anxiety and related mood disorders are performed in rodents, and a good model is chronic unpredictable stress (CUS). In this study, we have attempted to understand the molecular basis of the neuroglial and behavioral changes underlying CUS-induced mood disorders in the simplest vertebrate model, the zebrafish, Danio rerio. Zebrafish were subjected to a CUS paradigm in which two different stressors were used daily for 15 days, and thorough behavioral analyses were performed to assess anxiety and related mood disorder phenotypes using the novel tank test, shoal cohesion and scototaxis. Fifteen days of exposure to chronic stressors appears to induce an anxiety and related mood disorder phenotype. Decreased neurogenesis, another hallmark of anxiety and related disorders in rodents, was also observed in this zebrafish model. The common molecular markers of rodent anxiety and related disorders, corticotropin-releasing factor (CRF), calcineurin (ppp3r1a) and phospho cyclic AMP response element binding protein (pCREB), were also replicated in the fish model. Finally, using 2DE FTMS/ITMSMS proteomics analyses, 18 proteins were found to be deregulated in zebrafish anxiety and related disorders. The most affected process was mitochondrial function, 4 of the 18 differentially regulated proteins were mitochondrial proteins: PHB2, SLC25A5, VDAC3 and IDH2, as reported in rodent and clinical samples. Thus, the zebrafish CUS model and proteomics can facilitate not only uncovering new molecular targets of anxiety and related mood disorders but also the routine screening of compounds for drug development.
- Epidemiology of Psychotropic Drug Use in Rio de Janeiro, Brazil: Gaps in Mental Illness Treatments. [JOURNAL ARTICLE]
- PLoS One 2013; 8(5):e62270.
Estimate the prevalence of psychotropic drugs use in the city of Rio de Janeiro, Brazil, and establish its relationship with the presence of mental disorders.A probabilistic sample of non-institutionalized individuals, from the general population of Rio de Janeiro (n = 1208;turn out:81%), 15 years or older, who were interviewed using the Composite International Diagnostic Interview 2.1 (depression, anxiety-phobia, OCD\PTSD, alcoholism sections), and asked about their psychotropic use during a 12 and one-month period before the interview. Data were collected between June/2007-February/2008.The prevalence was estimated with a confidence interval of 95%. The associations between psychotropics use and mental disorders were analyzed through a logistic regression model (Odds Ration - OR).The one-month prevalence of psychotropic drug use was 6.55%, 3.19% for men and 9.13% for women. Antidepressants were the most frequently used drug (2.78%), followed by anorectics (1.65%), tranquilizers (1.61%) and mood stabilizers (1.23%). General practitioners issued the highest number of prescriptions (46.3%), followed by psychiatrists (29.3%); 86.6% of the psychotropic drugs used were paid for by the patient himself. Individuals with increased likelihood of using psychotropic drugs were those that had received a psychiatric diagnosis during a one-month period before the study (OR:3.93), females (OR:1.82), separated/divorced (OR:2.23), of increased age (OR:1.03), with higher income (OR:2.96), and family history of mental disorder (OR:2.59); only 16% of the individuals with a current DSM IV diagnosis were using a psychotropic drug; 17% among individuals with a depression-related diagnosis and 8% with Phobic Anxiety Disorders-related diagnosis used psychotropics.Approximately 84% of individuals displaying some mental disorder did not use psychotropic drugs, which indicates an important gap between demand and access to treatment. A significant failure is evident in the health system for patients with mental disorders; this could be due to health workers' inability to recognize mental disorders among individuals.
- A Yoga and Compassion Meditation Program Reduces Stress in Familial Caregivers of Alzheimer's Disease Patients. [JOURNAL ARTICLE]
- Evid Based Complement Alternat Med 2013.:513149.
Familial caregivers of patients with Alzheimer's disease exhibit reduced quality of life and increased stress levels. The aim of this study was to investigate the effects of an 8-week yoga and compassion meditation program on the perceived stress, anxiety, depression, and salivary cortisol levels in familial caregivers. A total of 46 volunteers were randomly assigned to participate in a stress-reduction program for a 2-month period (yoga and compassion meditation program-YCMP group) (n = 25) or an untreated group for the same period of time (control group) (n = 21). The levels of stress, anxiety, depression, and morning salivary cortisol of the participants were measured before and after intervention. The groups were initially homogeneous; however, after intervention, the groups diverged significantly. The YCMP group exhibited a reduction of the stress (P < 0.05), anxiety (P < 0.000001), and depression (P < 0.00001) levels, as well as a reduction in the concentration of salivary cortisol (P < 0.05). Our study suggests that an 8-week yoga and compassion meditation program may offer an effective intervention for reducing perceived stress, anxiety, depression, and salivary cortisol in familial caregivers.
- Psychological factors and coronary heart disease. [JOURNAL ARTICLE]
- ARYA Atheroscler 2013 Jan; 9(1):102-111.
Although psychological factors play an important role in coronary heart diseases (CHD), it seems there is a need for more researches in this respect. The present study aimed to review psychological factors, including depression, anxiety and stress related to etiology and prognosis of CHD.This was a review on medical and psychological literatures, particularly in the years 1995-2012.As protective factor or risk factor, psychological factors play an important role in CHD.Given the findings of this study, it seems necessary that we pay attention to psychological factors, as independent risk factors or protective factors for CHD.
