RESUMO

The central nervous system (CNS) exerts a strong regulatory influence over the cardiovascular system in response to environmental demands. Floatation-REST (Reduced Environmental Stimulation Therapy) is an intervention that minimizes stimulation from the environment, yet little is known about the autonomic consequences of reducing external sensory input to the CNS. We recently found that Floatation-REST induces a strong anxiolytic effect in anxious patients while paradoxically enhancing their interoceptive awareness for cardiorespiratory sensations. To further investigate the physiologic nature of this anxiolytic effect, the present study measured acute cardiovascular changes during Floatation-REST using wireless and waterproof equipment that allowed for concurrent measurement of heart rate, heart rate variability (HRV), breathing rate, and blood pressure. Using a within-subjects crossover design, 37 clinically anxious participants with high levels of anxiety sensitivity and 20 non-anxious comparison participants were randomly assigned to undergo a 90-min session of either Floatation-REST or an exteroceptive comparison condition that entailed watching a relaxing nature film. Measures of state anxiety and serenity were collected before and after each session, while indices of autonomic activity were measured throughout each session. HRV was calculated using both time-series and frequency domain analyses. Linear mixed-effects modeling revealed a significant main effect of condition such that relative to the film condition, Floatation-REST elicited significant decreases (p < 0.001) in diastolic blood pressure, systolic blood pressure, breathing rate, and certain metrics of HRV including the standard deviation of the interbeat interval (SDNN), low-frequency HRV, and very low-frequency HRV. Heart rate showed a non-significant trend (p = 0.073) toward being lower in the float condition, especially toward the beginning of the session. The only metric that showed a significant increase during Floatation-REST was normalized high-frequency HRV (p < 0.001). The observed physiological changes were consistent across both anxious and non-anxious participants, and there were no significant group by condition interactions. Blood pressure was the only cardiac metric significantly associated with float-related reductions in state anxiety and increases in serenity. These findings suggest that Floatation-REST lowers sympathetic arousal and alters the balance of the autonomic nervous system toward a more parasympathetic state.

RESUMO

Hyperinsulinemia promotes fat accumulation, causing obesity. Being an inflammatory state, obesity can induce further inflammation and is a risk factor for HPA (hypothalamic pituitary axis) dysregulation through hypercortisolism-related hyperglycemia. In another hypothesis, the sympathetic nervous system (SNS) plays a significant role in the regulation of hormone secretion from the pancreas such as an increase in catecholamines and glucagon as well as a decrease in plasma insulin levels, a disruption on SNS activity increases insulin levels, and induces glycogenolysis in the liver and lipolysis in adipose tissue during hypoglycemia. Hyperglycemia-hyperinsulinemia exacerbates inflammation and increases the oxidative stress along with regulating the levels of norepinephrine in the brain sympathetic system. Increased inflammatory cytokines have also been shown to disrupt neurotransmitter metabolism and synaptic plasticity which play a role in the development of depression via inhibiting serotonin, dopamine, melatonin, and glutamate signaling. An increased level of plasma insulin over time in the absence of exercising causes accumulation of lipid droplets in hepatocytes and striated muscles thus preventing the movement of glucose transporters shown to result in an increase in insulin resistance due to obesity and further culminates into depression. Further hyperinsulinemia-hyperglycemia condition arising due to exogenous insulin supplementation for diabetes management may also lead to physiological hyperinsulinemia associated depression. Triple therapy with SSRI, bupropion, and cognitive behavioral therapy aids in improving glycemic control, lowering fasting blood glucose, decreasing the chances of relapse, as well as decreasing cortisol levels to improve cognition and the underlying depression. Restoring the gut microbiota has also been shown to restore insulin sensitivity and reduce anxiety and depression symptoms in patients.

RESUMO

According to the interpersonal theory of suicide, the perception of imposing a burden on loved ones increases the risk for suicidal ideation. Little research, however, has examined the interaction of burdensomeness with cognitive variables in predicting suicidal ideation in college students even though the relationship between burdensomeness and ideation may be contingent on levels of cognitive risk factors. The present study thus examined the relationships between burdensomeness, hopelessness, coping competence, and suicidal ideation. Questionnaires were administered to 279 undergraduate students from a university in the Midwest United States. After controlling for depression, hopelessness, and coping competence, burdensomeness significantly predicted ideation and accounted for variance above and beyond the control variables. Moreover, the relationship between burdensomeness and suicidal ideation was significantly moderated by coping competence and hopelessness. The findings suggest that perceived burdensomeness plays a critical role in the risk for suicide in college students. More specifically, the findings suggest that coping competence and hopelessness can be ideal targets for interventions as changes in these variables may attenuate the association between perceived burdensomeness and suicidal ideation.

RESUMO

We comment on arguments about internet and smartphone use disorders by Montag, Wegmann, Sariyska, Demetrovics, and Brand (2020). Although not currently official diagnoses, we emphasize that for some individuals, excessive internet/smartphone use can have dangerous consequences. We discuss the challenges with ICD-11 codifying only internet gaming as an internet use-related disorder, neglecting other types of excessive internet users. Montag et al.'s approach to classifying a broader range of internet use disorders seems more fair than the current system in aiding individuals needing treatment resources for excessive internet use.

RESUMO

Aside from depression and anxiety, less is known about the relationship of problematic smartphone use (PSU) to other psychopathology- related variables. The authors' aim was to test previously neglected variables in relation to PSU: rumination and excessive reassurance seeking behavior (ERSB). The authors recruited 295 college students for a web-based survey of smartphone use frequency, PSU, depression and anxiety, ruminative thinking, and ERSB. The authors tested linear regression and mediation models, assessing rumination and ERSB as mediating associations between depression/anxiety severity with PSU, adjusting for age, sex, and smartphone use frequency. Results demonstrate that ERSB was significantly related to PSU severity, and ERSB mediated the association between rumination and PSU. Furthermore, the combination of rumination and ERSB mediated relations between both depression and anxiety severity with PSU. Results provide evidence for ERSB as an important variable in understanding relationships between psychopathology symptoms and PSU severity among college students.

RESUMO

In the present paper, we examine the literature studying relations between problematic smartphone use (PSU) and anxiety symptom severity. We first present background on the health advantages and disadvantages of using a smartphone. Next, we provide caveats in distinguishing healthy smartphone use from unhealthy PSU, and we discuss how PSU is measured. Additionally, we discuss theoretical frameworks explaining how some people develop PSU, including Uses and Gratifications Theory, and Compensatory Internet Use Theory. We present our own theoretical model of how PSU is specifically related to anxiety. We discuss and review mental health constructs associated with PSU severity, based on prior literature. Next, we systematically review the research on PSU severity in relation to anxiety symptoms, given the recent growth of studies on this research question. Finally, we offer implications and recommendations for future research in this area.

RESUMO

BACKGROUND: Research literature on problematic smartphone use, or smartphone addiction, has proliferated. However, relationships with existing categories of psychopathology are not well defined. We discuss the concept of problematic smartphone use, including possible causal pathways to such use. METHOD: We conducted a systematic review of the relationship between problematic use with psychopathology. Using scholarly bibliographic databases, we screened 117 total citations, resulting in 23 peer-reviewer papers examining statistical relations between standardized measures of problematic smartphone use/use severity and the severity of psychopathology. RESULTS: Most papers examined problematic use in relation to depression, anxiety, chronic stress and/or low self-esteem. Across this literature, without statistically adjusting for other relevant variables, depression severity was consistently related to problematic smartphone use, demonstrating at least medium effect sizes. Anxiety was also consistently related to problem use, but with small effect sizes. Stress was somewhat consistently related, with small to medium effects. Self-esteem was inconsistently related, with small to medium effects when found. Statistically adjusting for other relevant variables yielded similar but somewhat smaller effects. LIMITATIONS: We only included correlational studies in our systematic review, but address the few relevant experimental studies also. CONCLUSIONS: We discuss causal explanations for relationships between problem smartphone use and psychopathology.

RESUMO

BACKGROUND: To date only a few published studies have examined the effect of disorder-relevant stressors on heart rate variability (HRV) in participants meeting a clinical diagnosis of GAD, with conflicting results. The primary aim of this study was to determine if GAD is associated with lower HRV at rest, and whether vagal regulation during task varies by type (i.e., baseline, anticipation, imagery, or worry). METHODS: This study investigated resting cardiac vagal tone and vagal regulation in a sample of 40 participants with or without a validated diagnosis of generalized anxiety disorder (GAD). High-frequency heart rate variability (HF-HRV) was used to index cardiac vagal activity. RESULTS: GAD was associated with vagal withdrawal during both imagery and worry inductions, but no group differences in resting vagal tone or worry were observed. LIMITATIONS: Methodological limitations include inherent limits to generalizability of laboratory-based findings; specifically worry induction and cardiac reactivity to lab-based stressors. CONCLUSIONS: The results support the notion that GAD is associated with vagal withdrawal during active bouts of idiographic worry and imagery, and question the assumption that GAD is associated with low resting vagal tone. In light of polyvagal theory these findings provide additional support for the presence of emotion regulation deficits in GAD, and identify specific ANS processes that underlie GAD.

RESUMO

Self-monitoring of blood glucose (SMBG) has been recommended for people with type 2 diabetes mellitus. This trial tested an automated self-management monitor (ASMM) that reminds patients to perform SMBG, provides feedback on results of SMBG, and action tips for improved self-management. This delayed-start trial randomized participants to using the ASMM immediately (IG), or following a delay of 6 months (DG). Glycated hemoglobin (HgbA1c) level and survey data was collected at home visits every 3 months. 44 diabetic men and women, mean age 70, completed the 12-month trial. Baseline HgbA1c was 8.1 % ± 1.0, dropping to 7.3 ± 1.0 by 9 months, with a 3-month lag in the DG (F = 3.56, p = 0.004). Decrease in HgbA1c was significantly correlated to increased frequency of SMBG, R = 0.588, p < 0.01. Providing older diabetics with objective immediate contingent feedback resulted in more frequent SMBG that correlated with better glycemic control. This type of technology may provide real-time feedback not only to patient users, but to the health care system, allowing better integration of provider recommendations with patient-centered action.

RESUMO

While previous research on deterioration has focused on identifying individuals at risk for negative outcomes, little is known about the nature or pattern by which deterioration occurs. The problem of deterioration is especially salient in training clinics; a setting in which higher deterioration rates have been reported. Two studies were designed to test the applicability of the phase model to deterioration in a training clinic and to replicate the model with a training clinic referral-base sample. In Study 1, the course of therapy was monitored for 135 clients. For the 38 clients who deteriorated during therapy, a model where increased symptoms (demediation) reliably preceded both decreased functioning (dehabilitation) and decreased well-being (demoralization) was found. In Study 2, the same three phases were prospectively monitored for 914 undergraduate students on a weekly basis throughout a single semester. For the 158 individuals who deteriorated during this time, a model where demediation reliably preceded dehabilitation, which preceded demoralization was found. These results have clinical implications for the use of tailored intervention strategies focusing on the deterioration phases.

RESUMO

Research examining treatment dropout is hindered by the inconsistencies in the methods used to operationalize the construct. In this article an operationalization based on the criteria of attaining clinically significant change prior to treatment discontinuation is reintroduced and compared with other existing dropout classification systems. A dropout rate of 77% was found in a university-based training clinic sample by using the clinically significant change (CSC) definition. This classification showed little agreement to classifications made by other popularly used definitions of dropout (median split, intake only, missed appointment, and therapist judgment). Further analysis indicated that the other popularly used definitions frequently classified clients as treatment dropouts when recovery had occurred or as treatment completers when recovery had not occurred. Uses and limitations of the CSC method and other popular definitions of treatment dropout are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

RESUMO

BACKGROUND AND PURPOSE: Transesophageal echocardiography is used to detect the aortic arch pathology during diagnostic workup of ischemic stroke events. Conventional angiography is increasingly used in diagnosing and treating atherosclerotic vascular lesions in patients with ischemic stroke. Although catheter-based aortography can be performed with cerebral angiography, there is limited information about the utility of aortography in identifying atherosclerotic abnormalities of the aortic arch. METHODS: A retrospective chart review was performed to identify patients who underwent aortography as part of their angio-graphic study and transesophageal echocardiography. Both studies were reviewed independently in the absence of knowledge of the results of the other study. The findings of these aortograms were correlated with the findings of transesophageal echocardiography. RESULTS: A total of 34 patients underwent both aortography and echocardiography. Of a total of 34 trans esophageal echocardiograms, 29 showed abnormal findings in the aorta (85%) and 5 appeared normal (15%). These aortic abnormalities included mild to moderate atherosclerosis in 18 cases (52%), moderate to severe atherosclerosis in 4 cases (12%), and severe atherosclerosis in 7 cases (21%). None of these abnormalities were detected by aortography. No disease was visualized in the origin of the supraaortic arteries. CONCLUSIONS: Aortic arch atherosclerosis is common in patients with ischemic stroke; however, aortograms acquired during conventional angiography fail to identify abnormalities detected on transesophageal echocardiogram.
