Abstract

Treatment-resistant depression (TRD) describes those who have not responded to at least two other treatments for depression. These individuals require additional support to reach remission of their symptoms. Psychotherapy modalities can be a way to augment treatment of depression without additional medications. This article discusses the use of interpersonal therapy, dialectical behavioral therapy, radically open dialectical behavioral therapy, cognitive-behavioral therapy, and intensive short-term dynamic psychotherapy. All of these therapies can achieve increased rates of remission and improvement of depressive symptoms when compared to treatment as usual. No significant adverse events have noted in the studies that have looked at these various treatments. Areas for future research include delineation of which specific modalities are best suited to addressing the needs of individual patients. As part of a comprehensive treatment plan, psychotherapy should be considered when addressing TRD. [Psychiatr Ann. 2024;54(6):e182–e185.] [ABSTRACT FROM AUTHOR]

Abstract

Cognitive fusion occurs when people experience their thoughts as literally true and allow them to dictate behavior. Fusion has been shown to be associated with increased symptoms of post-traumatic stress disorder (PTSD) and depression; however, the association between change in cognitive fusion, PTSD, and depression symptoms has been relatively uninvestigated. Our study aims to examine the associations between PTSD, depression symptoms, and cognitive fusion in Canadian veterans from pre- to post-treatment. Clients (N = 287) completed measures of PTSD symptom severity, depression symptom severity, and cognitive fusion at pre- and post-treatment. Our results supported that pretreatment PTSD and depression symptom severity were found to be negatively associated with changes in pre- to post-treatment cognitive fusion, while pretreatment cognitive fusion was not associated with changes in depression or PTSD symptoms. Furthermore, pretreatment depression symptoms predicted pre- to post-treatment changes in PTSD symptoms. However, pretreatment PTSD symptoms did not predict changes in depression symptoms. These findings highlight the importance of understanding the bidirectional associations between PTSD, depression, and cognitive fusion. Furthermore, our results are indicative of PTSD and depression symptoms playing a role in the change in cognitive fusion (e.g., defusion) and of depression playing a larger role in the maintenance of PTSD symptoms. Theoretical and practical implications are discussed. [ABSTRACT FROM AUTHOR]

Abstract

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Abstract

The gut mucosal barrier plays a key role in the physiology of gastrointestinal (GI) tract, preventing under homeostatic conditions, the epithelial cells of the gastric mucosa from hydrochloric acid and intestinal mucosa from alkaline secretion, food toxins and pathogenic microbiota. Previous studies have documented that blockade of both isoforms of cyclooxygenase (COX): constitutive (COX-1) and inducible (COX-2), as well NO synthase in the stomach exacerbated the gastric damage induced by various ulcerogens, however, such as effects of non-selective and selective inhibition of COX-1, COX-2 and NOS enzymes on colonic damage have been little studied. The supplementation of NO by intragastric (i.g.) treatment with NO-releasing compound NO-aspirin (NO-ASA) or substrate for NO synthase L-arginine ameliorated the damage of upper GI-tract, but whether similar effect can be observed in colonic mucosa associated with the experimental colitis, and if above mentioned compounds can be effective in aggravation or protection of experimental colitis remains less recognized. In this study rats with experimental colitis induced by intrarectal administration of 2,4,6-trinitrobenzosulphonic acid (TNBS) were daily treated for 7 days with: 1) vehicle (i.g.), 2) ASA 40 mg/kg (i.g.), 3) rofecoxib 10 mg/kg (i.g.), 4) resveratrol 10 mg/kg (i.g.), 5) NO-ASA 40 mg/kg (i.g.), 6) L-arginine 200 mg/kg (i.g.) with or without of L-NNA 20 mg/kg (i.p.). The macroscopic and microscopic area of colonic damage was determined planimetrically, the colonic blood flow (CBF) was assessed by Laser flowmetry, and the oxidative stress biomarkers malondialdehyde and 4-hydroxynonenal (MDA+4-HNE), the antioxidative factors superoxide dismutase (SOD) and glutathione (GSH), as well as proinflammatory cytokines in the colonic mucosa (tumor necrosis factor alpha (TNF-a) and interleukin-1beta (IL-1β)) were measured. We have documented that administration of TNBS produced gross and microscopic colonic damage and significantly decreased CBF (p<0.05). Treatment with ASA significantly increased the area of colonic damage (p<0.05), an effect accompanied by a significant decrease in the CBF, the significant increment of MDA+4- HNE, and the attenuation of the antioxidative properties in colonic mucosa, documented by a significant decrease of SOD activity and GSH concentration, and elevation of the colonic tissue levels of TNF-α and IL-1β comparing to control Veh-treated TNBS rats. Administration of rofecoxib or resveratrol also significantly increased the colonic damage and significantly decreased the CBF, causing an increase in MDA+4-HNE and mucosal content of TNF-α and IL-1α and a significant decrease of the SOD activity and GSH content (p<0.05), however, these changes were significantly less pronounced as compared with ASA. On the contrary, the treatment with NO-ASA, or L-arginine, significantly diminished the area of colonic lesions, the MDA+4-HNE concentration, attenuated the TNF-α and IL- 1β levels, while increasing the CBF, SOD activity and GSH content (p<0.05). The concomitant treatment of L-NNA with rofecoxib or resveratrol reversed an increase in area of colonic damage and accompanying changes in CBF, colonic mucosa TNF-α and IL-1β levels, the MDA+4-HNE concentration, and SOD activity and GSH content comparing to those observed in TNBS rats treated with these COX-inhibitors alone (p<0.05). In contrast, cotreatment with L-NNA and NO-ASA or L-arginine failed to significantly affect the decrease of colonic lesions accompanied by the rise in CBF, the attenuation of MDA+4-HNE concentration, TNF-α and IL-1β levels, SOD activity and GSH content exerted by NO-ASA- or L-arginine treatment of the respective control TNBS-rats without L-NNA administration. These observations suggest that 1) the increase of NO availability either from NO-releasing donors such as NO-ASA or NO precursors such as L-arginine, can inhibit the inflammatory and microvasculature alterations, as well as increase in lipid peroxidation due to the enhanced efficacy of these compounds to increase the antioxidative properties of colonic mucosa, 2) unlike ASA which exacerbated the severity of colitis, the treatment with rofecoxib, the specific 'safer' COX-2 inhibitor or resveratrol, the polyphenolic compound known to act as the dual COX-1 and COX-2 inhibitor, can attenuate the colonic damage during course of TNBS colitis possibly via antiinflammatory and antioxidative properties, and 3) the blockade of endogenous NO activity by L-NNA which also exacerbated the severity of mucosal damage in colitis, can abolish the sparing effect of rofecoxib and resveratrol indicating the NO bioavailability plays an important role in enhanced efficacy of both specific and dual COX inhibitors to ameliorate the experimental colitis.

Abstract

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = −0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.

Abstract

Public health crises, including the ongoing COVID-19 pandemic, have wide reaching implications on mental health, and have resulted in unique OCD presentations specific to respective crises. The distribution of highly efficacious and effective vaccines for COVID-19 present a crossroads for the COVID-19-specific OCD presentation, including the potential for COVID-19 presentation perpetuation or remission in the face of vaccinations. Individual differences may play a unique role in who does and does not see a reduction of OCD symptoms specific to this virus as a function of vaccination status. Here, we discuss prior health crises that have resulted in unique OCD presentations, review relevant assessment and intervention guidelines, discuss potential implications that vaccines may have on this COVID-19-specifc presentation, and provide case presentations and future recommendations for treatment providers and researchers.

31. Maladaptive Schemas and Posttraumatic Stress Disorder Symptom Severity: Investigating the Mediating Role of Posttraumatic Negative Self-Appraisals among Patients in a Partial Hospitalization Program.

Abstract

Maladaptive schemas have been linked with increased posttraumatic stress disorder (PTSD) symptoms. Posttraumatic negative self-appraisals (i.e., posttraumatic shame and self-blame) have also been empirically supported as contributors to PTSD symptom severity following traumatic events. These associations are well known; however, the pathways between maladaptive schemas and PTSD symptoms remain largely unclear. The present study aimed to examine the mediating effects of posttraumatic negative self-appraisals (shame and self-blame) on the association between maladaptive schemas and PTSD symptom severity in patients completing a partial hospitalization program. Patients (N = 98) completed measures of early maladaptive schemas, posttraumatic shame, posttraumatic self-blame, and PTSD symptom severity at intake. Posttraumatic negative self-appraisals mediated the association between maladaptive schemas and PTSD symptom severity. When we examined the specific mediating effects of shame and blame – rather than negative self-appraisals overall – shame was a significant mediator (b =.153, 95% CI [.031,.296]), but not blame (b =.038, 95% CI [−.083,.204]). Further, posttraumatic shame mediated the association between two of the four schema domains – disconnection & rejection (b =.092, 95% CI [.030,.201]) and impaired autonomy & performance (b =.047, 95% CI [.002,.124]) – and PTSD symptom severity. These findings highlight the importance of posttraumatic shame in the association between maladaptive schemas and PTSD symptom severity. Theoretical and practical implications are discussed.

32. SIMULTANEOUS DETECTION OF MELATONIN AND SIX METABOLITES OF L-TRYPTOPHAN PATHWAY IN RAT GASTRIC MUCOSA.

Abstract

Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine synthesized in vertebrates mainly in the pineal gland, and is known to be involved mainly in thermoregulation and control of the circadian rhythm. That indoleamine can affect the auto-, para- and endocrine pathways, regulating body functions and affecting the metabolism of animals and humans. In addition to the pineal gland, melatonin can be synthesized in many extra-pineal tissues, mainly in the gastrointestinal tract. Previous studies have shown that melatonin plays an important role in the defense system of the gastrointestinal mucosa, demonstrating a protective effect on the gastrointestinal tract and the acceleration of healing of chronic ulcers through the scavenging of reactive oxygen metabolites (ROS) and the activation of protective nitric oxide (NO) and vasodilator neuropeptides released from the sensory afferent neurons. The process of converting the melatonin precursor L-tryptophan into melatonin is already known, but not all aspects of this process for the synthesis of other metabolites of this pathway have been fully elucidated and this issue remains poorly understood. In this study, the conversion of L-tryptophan to melatonin and other metabolites was determined in gastric mucosa collected from rats with or without intragastric (i.g.) melatonin or L-tryptophan administration, both administered at a single dose of 50 mg/kg. For the determination of five metabolites of L-tryptophan: kynurenine, 5-hydroxytryptamine, 5-hydroxytryptophan, anthranilic acid, indole-3-acetic acid together with melatonin, we have modified the previously developed high-performance liquid chromatography (HPLC) method using a native fluorescence detection system and UV-VIS. The obtained results show that: 1) L-tryptophan is converted into melatonin in the gastric mucosa during the day, e.g. after eating a meal containing L-tryptophan, as it was imitated and confirmed by our study, in which this amino acid was administered directly to the stomach, 2) the gastric mucosa is capable of producing melatonin in much greater amounts than those recorded in the blood serum of rats given a single dose of L-tryptophan, and 3) apart from melatonin, the only serum levels of these five metabolites of the L-tryptophan metabolic pathway are detectable, while their level in the gastric mucosa is low and barely detectable under physiological conditions. Our present observations support the notion that the gastric mucosa is one of the main sources of melatonin production from L-tryptophan outside the pineal gland. [ABSTRACT FROM AUTHOR]

Abstract

A model is developed which can be used to understand how collision geometry can dictate product state lambda doublet ratios in direct bimolecular reactions that produce diatomic products in a Π molecular energy state. The predicted lambda doublet ratio is A'/A' = 2 for unconstrained collision geometry, while the two limiting case geometries of exclusive end-on collisions and exclusive side-on collisions yield lambda doublet ratios of A'/A'= ∞ and A'/A'= 1, respectively. The theory is derived and used to interpret the experimental lambda doublet ratio of OH (υ = 0) from the H +N[sub 2]O→OH+N[sub 2] reaction. [ABSTRACT FROM AUTHOR]
