Use of verbal de-escalation in reducing need for mechanical restraint in patients with psychotic disorders during non-voluntary transfers from home to the psychiatric emergency department

Introduction

Little is known about the need for mechanical restraint during non-voluntary transfers from patient’s homes to the psychiatric emergency department in patients diagnosed with Paranoid Schizophrenia. Although there is no evidence of its efficacy, one of the main tools used for the reduction of mechanical restraints is verbal de-escalation training.

Objectives

The aim is to describe which symptoms predispose to mechanical restrain in patients with Paranoid Schizophrenia transferred in a non-voluntary manner from home to the psychiatric emergency department, and the effect on reducing mechanical restraints after receiving verbal de-escalation training.

Methods

All patients with Paranoid Schizophrenia who, after being visited by a home psychiatry team, have required non-voluntary transfer from their homes to the psychiatric emergency department were selected (N = 442).

Results

Young age, being male, having a poor adherence to treatment, higher scores for de following variables; Excitement, Grandiosity, Suspiciousness, Hostility, Abstract thinking, Motor tension, Uncooperativeness, Poor attention, Lack of insight and Poor impulse control as well as lower scores in motor retardation on the PANSS, are related to a higher frequency of mechanical restrain (P<0,005). Before the verbal de-escalation training, 43.9% of the transferred patients required mechanical restraint, after the training, the need for restraints was reduced to 25.5% (P<0.001).

Conclusions

Training in verbal de-escalation has allowed an important reduction in mechanical restraints in patients with schizophrenia who have required non-voluntary transfers from home to the psychiatric emergency department.

Correlates of Mental Health in Adolescents and Young Adults with Cerebral Palsy: A Cross-Sectional Analysis of the MyStory Project

Background: It is important to gain a better understanding of mental health issues in adolescents and young adults (AYA) with cerebral palsy (CP). In this cross-sectional study, we explore if demographics, social and clinical questionnaire scores, and cortisol levels in hair samples from AYA with CP are associated with higher scores on anxiety and/or depression questionnaires. Methods: Data from a community-based sample of 63 AYA with CP (30 females; ages 16 to 30 (median age of 25)) were analyzed. Forty-one (65%) participants (20 females) provided a hair sample. Outcomes were assessed using bivariate linear regression analyses and hierarchical regression analyses. Results: Clinical depressive and anxiety symptoms were present in 33% and 31% of participants, respectively. Family functioning, B = 9.62 (95%CI: 5.49–13.74), fatigue, B = 0.15 (95%CI: 0.05–0.25), and pain, B = 1.53 (95%CI: 0.48–2.58) were statistically significant predictors of depressive symptoms. Fatigue, B = 0.24 (95%CI: 0.12–0.35) and pain, B = 1.63 (95%CI: 0.33–2.94) were statistically significant predictors of anxiety. Cortisol levels from hair samples were not found to be associated with depressive symptoms or anxiety. Conclusions: A high prevalence of mental health problems and co-occurring physical problems was found in AYA with CP. Integrating mental support into regular care for AYA with CP is recommended.

Antithrombotic Treatment after Carotid Stenting in Patients with Concomitant Atrial Fibrillation

BACKGROUND AND PURPOSE

Antithrombotic therapy following carotid artery stent placement with concomitant atrial fibrillation is not well-established. Our aim was to assess the safety and efficacy of the combination of direct oral anticoagulants and a P2Y12 inhibitor at 30 days after carotid artery stent placement in patients with atrial fibrillation.

MATERIALS AND METHODS

We designed an observational single-center study including patients who underwent carotid artery stent placement with concomitant atrial fibrillation. We studied 3 groups according to antithrombotic therapy: 1) the direct oral anticoagulants plus clopidogrel (DC) group: receiving direct oral anticoagulants plus a P2Y12 inhibitor; 2) the triple therapy group: anticoagulation and dual antiplatelet therapy; and 3) the dual antiplatelet therapy group: following dual antiplatelet therapy alone. The safety outcome was a major or clinically relevant non-major bleeding event at the first month. The efficacy outcomes were the thromboembolic events (myocardial infarction, stroke, systemic embolism, or stent thrombosis).

RESULTS

Of 959 patients with carotid artery stent placement, 91 met the inclusion criteria, including 24 patients in the DC group, 42 patients in the triple therapy group, and 25 in the dual antiplatelet therapy group. The mean age was 72.27 (SD, 8.1 ) years, with similar baseline characteristics. The median CHA₂DS₂-VASc score for each group was 6 (interquartile range  = 5-6), 5 (interquartile range = 4-6), and 5 (interquartile range = 4-6), respectively. The median HAS-BLED score was 4 in the 3 groups (P = .17). The primary safety end point was 23.8% in the triple therapy group compared with 4% in the dual antiplatelet therapy group (P = .032), with no bleeding events in the DC group (P = .007). There was 1 stent thrombosis in DC group and a cardioembolic stroke in the dual antiplatelet therapy group (P = .41).

CONCLUSIONS

Among patients with carotid artery stent placement with atrial fibrillation, triple therapy confers a high bleeding risk. A regimen of direct oral anticoagulants plus a P2Y12 inhibitor might confer a good safety profile with significantly lower rates of bleeding and optimal efficacy.

Multicenter lupus register from Argentina, the RELESSAR database: Influence of ethnicity on disease phenotype

OBJECTIVE

The objective is to describe the main characteristics of patients with systemic lupus erythematosus (SLE) in Argentina and to examine the influence of ethnicity on the expression of the disease.

PATIENTS AND METHODS

RELESSAR is a multicentre register carried out by 106 researchers from 67 rheumatologic Argentine centres. It is a cross-sectional study of SLE (1982/1997 ACR) patients. RELESSAR electronic database includes demographic, cumulative SLE manifestations, SELENA-SLEDAI, SLICC-SDI, Katz's severity and Charlson's comorbidity indexes and treatment patterns.

RESULTS

We included 1,610 patients, 91.7% were female with a median age at diagnosis of 28.1 ± 12.8; 96.2% met ≥4 ACR 1982/97 criteria. Frequent manifestations were arthritis (83.5%), malar rash (79.5%), photosensitivity (75.3%), haematological (63.8%) and renal disease (47.4%), antinuclear antibodies (96%), anti-dsDNA (66.5%) and anti-Smith antibodies (29%). The mean Selena-SLEDAI score at last visit was 3.18 (SD 4.3) and mean SDI was 1 (SD 1.3). The accumulated treatments most frequently used were antimalarials (90.4%), corticosteroids (90%), azathioprine (31.8%), intravenous cyclophosphamide (30.2%), mycophenolate mofetil or mycophenolic acid (24.5%), methotrexate (19.3%), belimumab 5.3% and rituximab 5.1%. Refractory lupus was diagnosed in 9.3% of the cases. The main causes of death were lupus activity (25.0%), activity and concomitant infections (25.0%), infections (18.2%), vascular disease (13.6%) and cancer (4.5%). Mortality was associated with higher SLEDAI, Katz, damage indexes and comorbidities. Of the 1610 patients included, 44.6% were Caucasian, 44.5% Mestizo, 8.1% Amerindian and 1.2% Afro-Latin American. Mestizo patients had higher male representation, low socioeconomic status, more inadequate medical coverage, fewer formal years of education and shorter disease duration. Polyadenopathies and Raynaud's phenomenon were more frequent in Caucasians. In the logistic regression analysis higher damage index (OR 1.28, CI 95% 1.02-1.61, p = 0.03) remained associated to mestizo ethnicity.

CONCLUSIONS

This study represents the largest number of adult patients with SLE studied in Argentina. Caucasian patients were differentiated by having Raynaud's phenomenon and polyadenopathy more frequently, while patients of Mestizo origin had higher damage indexes.

Mobilizing Forward: An Interpretive Description of Supporting Successful Neonatal Intensive Care Unit-To-Home Transitions for Adolescent Parents

Pregnancy and parenting in adolescence and the transition home following the hospitalization of an infant in the neonatal intensive care unit (NICU) are two relatively complex phenomena; and whilst each have been consistently explored within the relevant literature, little is understood about the care required when they intersect. Using interpretive description methodology to guide our exploration, we conducted semi-structured interviews with 23 expert providers caring for adolescent parents involved in NICU-to-home transitions to describe this process in their practice. Findings suggest that supporting successful NICU-to-home transitions for adolescent parents relied strongly on understanding the impact of the NICU experience, establishing therapeutic relationships and facilitating supportive partnerships between the NICU and parents as well as the NICU and supportive services post-discharge. Findings highlight the opportunity for more integrated models of care within the NICU and extending into the community to address the complex biopsychosocial care needs of this parent population.

Biological embedding of child maltreatment: A systematic review of biomarkers and resilience in children and youth

OBJECTIVE

Child maltreatment (CM) is a widespread problem associated with poor mental and physical health outcomes. The underlying mechanisms of this link are not always well understood, however certain biological changes observed in maltreated individuals may play a role in connecting experience and outcome. This review specifically focuses on 2 markers of biological embedding, DNA methylation (DNAm) and telomere length (TL) in maltreated children and youth. As biomarker changes are not uniform among maltreated children, we additionally discuss biological and environmental resilience factors that may contribute to variability.

METHOD

We conducted a systematic review of Medline, Embase and PsycINFO databases for studies examining DNAm and/or TL in maltreated children and youth. Methodological quality of the included studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) checklists for cohort studies and randomized control trials. Data extraction focused on various factors including population and CM (type, chronicity, severity, and duration) characteristics.

RESULTS

The initial search returned 1,688 nonduplicate results, with 417 full text articles reviewed. Twenty-six articles from 16 studies were ultimately included of which 8 examined telomere length and 18 examined DNA methylation.

CONCLUSIONS

While some heterogeneity of findings was found, evidence supports differential changes in both biomarkers associated with CM. This review enhances understanding of the constellation of biological changes related to CM and consideration of the important role of resilience factors in mitigating risk. Elucidating these factors may highlight targets for future study and intervention development. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Associations between Lifetime Spanking/Slapping and Adolescent Physical and Mental Health and Behavioral Outcomes

BACKGROUND

Many parents use physical forms of punishment, including spanking to correct perceived misbehavior. While some authors suggest spanking/slapping is a distinct and "milder" form of physical punishment, parents' use of spanking is consistently associated with poor outcomes for their children. However, less is known about the relationship between spanking/slapping and health and behavioral outcomes in adolescence independent of other childhood adversities.

OBJECTIVES

The objectives of this study were to examine the associations between lifetime experiences of spanking on the bottom and/or slapping on the hand and 3 adolescent outcomes: (a) mental health disorders, (b) physical health conditions, and (c) defiant behaviors, after adjusting for other types of childhood adversities and child maltreatment.

METHODS

Cross-sectional data from the provincially representative 2014 Ontario Child Health Study (N = 6,537 dwellings, response rate = 50.8%) were used. The current study focused on one selected child aged 14 to 17 years within a household (n = 1,883) with data collected from the adolescent and the parent/caregiver. Logistic regression models were used to identify associations with lifetime experiences of spanking/slapping 3 or more times (vs. 0 to 2 times).

RESULTS

Lifetime spanking/slapping was independently associated with increased odds of mental health disorders, physical health conditions, and defiant behaviors in adolescence after adjusting for childhood adversities and child maltreatment (unadjusted and adjusted odds ratios ranging from 1.29 to 2.19).

CONCLUSIONS

These findings suggest that lifetime spanking/slapping is uniquely associated with harmful mental, physical, and behavioral outcomes in adolescence, and efforts should focus on its prevention.

Emotion regulation moderates between maternal adverse childhood experiences (ACEs) and oxytocin response

Exposure to adverse childhood experiences (ACEs) is associated with oxytocin dysregulation in women, such as decreased peripheral oxytocin concentrations, but little is known about vulnerability markers for oxytocin dysregulation in mothers exposed to ACEs. Identifying vulnerability markers may help inform future targets for prevention and intervention programmes. This study provided a preliminary examination of emotion regulation as a potential moderator of the association between maternal ACEs and peripheral oxytocin levels. The current study included a sample of 38 postpartum women. Women completed questionnaires on exposure to ACEs and difficulties with emotion regulation. At a clinic visit at 9 months postpartum, women provided plasma and salivary oxytocin samples anchored around a mother-infant interaction. Associations between maternal ACEs, three dimensions of difficulties with emotion regulation, and peripheral oxytocin concentrations were examined. Linear regression analyses showed that greater difficulties engaging in goal-directed behaviour (β =  - 0.50, p = 0.01) and more limited access to effective emotion regulation strategies (β =  - 0.68, p < 0.001) were related to reduced plasma oxytocin concentrations in postpartum women. Furthermore, in postpartum women reporting greater exposure to ACEs, higher levels of nonacceptance of emotional responses (β =  - 0.55, p = 0.01) and more limited access to effective emotion regulation strategies (β =  - 0.54, p = 0.01) were associated with reduced salivary oxytocin response (i.e. decreased change in oxytocin concentrations from baseline) following mother-infant interaction. Difficulties with emotion regulation may serve as a vulnerability marker for oxytocin dysregulation in postpartum women exposed to ACEs, and this suggests that emotion regulation may be an important target for future clinical interventions. Future research is recommended which replicates these preliminary results and which examines how emotion regulation and peripheral oxytocin levels in mothers exposed to ACEs are associated with parenting and child development outcomes.

Examining the unique contributions of parental and youth maltreatment in association with youth mental health problems

BACKGROUND

Extensive research seeks to understand the intergenerational impact of child maltreatment. However, it remains unclear how parent's history of child maltreatment (PCM) is associated with child mental health, after accounting for children's experiences of maltreatment and other proximal risk factors.

OBJECTIVE

This study examines the associations between PCM and youth internalizing and externalizing problems, while accounting for youth experiences of maltreatment (YM), and parent mental health and positive parenting.

PARTICIPANTS AND SETTING

Youth aged 14 to 17 years (N = 2266) participated in the 2014 Ontario Child Heath Study.

METHODS

Parents and youth reported their experiences of child maltreatment. Parent-report and self-reports of youth internalizing and externalizing problems were also collected. Number of subtypes of maltreatment and specific subtypes of maltreatment were examined. Parents reported their own mental health problems and positive parenting practices.

RESULTS

Regarding number of maltreatment subtypes, initially PCM was associated with parent-reported, but not self-reported, youth internalizing and externalizing problems. After accounting for YM, parent mental health problems and positive parenting, only YM remained significant. Regarding specific subtypes of maltreatment, both parent and youth emotional abuse were related to parent- and youth-reported internalizing and externalizing problems, after controlling for other maltreatment subtypes. However, the effects of parent emotional abuse became nonsignificant after accounting for YM and proximal risk factors.

CONCLUSIONS

Findings indicate: 1) the unique associations between specific PCM and YM subtypes and youth mental health problems; 2) the role of proximal risk factors in explaining the association between PCM and youth mental health; and 3) the importance of multiple informants of youth mental health problems.

Public health nurses' perceptions of their interactions with child protection services when supporting socioeconomically disadvantaged young mothers in British Columbia, Canada

BACKGROUND

Children of girls and young women experiencing socioeconomic disadvantage are at risk of maltreatment and associated health and developmental problems. Nurse-Family Partnership (NFP) is an early intervention program designed to improve child and maternal health outcomes. The effectiveness of NFP is being evaluated in British Columbia (BC) through a randomized controlled trial, augmented by a process evaluation to identify influences on how NFP was implemented.

OBJECTIVE

To describe how public health nurses providing NFP perceived their interactions with child protection professionals.

PARTICIPANTS AND SETTING

Forty-seven public health nurses across BC.

METHODS

The principles of interpretive description informed the qualitative component of the process evaluation. Data from interviews and focus groups were analyzed using the framework analysis approach. A thematic framework was generated through processes of coding, charting and mapping, with a focus on organizational and systems influences.

RESULTS

Nurses' practice in supporting families often involved engagement with child protection services. Four themes about the nature of this work were identified: 1) developing a deeper understanding of the disciplinary perspectives of child protection, 2) striving for strengthened collaboration, 3) navigating change and uncertainty, and 4) responding to family and community complexity.

CONCLUSIONS

Participants valued the contribution of child protection professionals and expressed willingness to collaborate to support families. However, collaboration was constrained by multiple structural barriers. Collaborative models offer possibilities for integrated practice, although can be difficult to implement within current health and child protection systems and child protection regulatory contexts.

An iterative approach to promoting departmental wellbeing during COVID-19

RATIONALE, AIMS, AND OBJECTIVES

Addressing wellbeing among learners, faculty, and staff during the COVID-19 pandemic is a challenge for many clinical departments. Continued and systemic supports are needed to combat the pandemic's impact on mental health and wellbeing. This article describes an iterative approach to conducting a needs assessment and implementing a COVID-19-related wellness initiative in a psychiatry department.

METHODS

Development of the initiative followed the Plan-Do-Study-Act (PDSA) quality improvement cycle and was informed by Shanafelt and colleagues' framework for supporting healthcare workers during the COVID-19 pandemic. Key features included the establishment of a Wellness Working Group, the curation of relevant resources on the Department's website, and the deployment of regular, monthly surveys that informed the creation of further supports, such as a weekly online drop-in support group.

RESULTS

Survey response rates ranged from 22% to 32% (n = 90-127) throughout our initiative. Across multiple surveys, approximately 80% of respondents reported feeling supported or very supported by the Department, and 90% were satisfied or very satisfied with the quantity and quality of information provided. Our support group and resources page were accessed by nearly one-quarter and one-third of respondents, respectively, with satisfaction rates of 81% or higher. Consistent with the Department's mandate, ensuring equity was a key focus of the Working Group throughout its operations.

CONCLUSIONS

There is potential for this model to be scaled to create a faculty-wide, institution-wide, or regional approach to addressing wellbeing. Other departments may also wish to adopt similar approaches to supporting their members during this challenging time.

The ethics of child maltreatment surveys in relation to participant distress: Implications of social science evidence, ethical guidelines, and law

Epidemiological surveys measuring the prevalence of child maltreatment generate essential knowledge that is required to enhance human rights, promote gender equality, and reduce child abuse and neglect and its effects. Yet, evidence suggests Institutional Review Boards (IRBs) may assess the risk of these studies using higher than normal thresholds, based on a perception they may cause high distress to participants. It is essential for IRBs and researchers to have an accurate understanding of the nature and extent of participant distress associated with these studies, and of the duties of researchers towards survey participants, so that meritorious research is endorsed and duties to participants discharged. Assessment by IRBs of the ethics of such research must be appropriately informed by scientific evidence, ethical principles, and legal requirements. This article adds to knowledge by considering participant distress in child maltreatment surveys and its appropriate ethical and operational treatment. We provide an updated overview of scientific evidence of the frequency and severity of distress in studies of child maltreatment, a review of ethical requirements including a focus on beneficence and participant welfare, and a new analysis of researchers' legal duties towards participants. Our analyses demonstrate that participant distress is infrequent and transitory, that researchers can satisfy ethical requirements towards participants, and that legal liability does not extend to emotional distress. Informed by these bodies of knowledge, we distil key principles of good epidemiological practice to provide solutions to operational requirements in these surveys, which both fulfil ethical requirements to participants, and demonstrate trauma-informed practice.

Associations of Adverse Childhood Experiences with Frailty in Older Adults: A Cross-Sectional Analysis of Data from the Canadian Longitudinal Study on Aging

INTRODUCTION

Frailty in older adults, characterized by a decline in multiple physiological systems and increasing vulnerability to loss of independence, disability, and death, is a public health priority in developed countries. Etiology of frailty extends across the lifespan and may begin in early life, but empirical evidence for this association is scarce. In this study, we examined whether adverse childhood experiences (ACEs) are associated with frailty in later life.

METHODS

We conducted a cross-sectional analysis of data for a population-based sample of 27,748 adults aged 45-85 years from the Canadian Longitudinal Study on Aging. The frailty index (FI) was computed with 76 health-related characteristics of physical and cognitive performance, self-rated health, chronic conditions, visual and hearing ability, activities of daily living, and well-being. Self-reported exposure to ACEs included physical, emotional, and sexual abuse, neglect, and witnessing intimate partner violence prior age of 16 and parental death, divorce, and living with a family member with mental illness prior age of 18. Generalized linear regression models with gamma error distribution and identity link function, adjusted for age and sex, were used to examine associations of each ACE type and the number of ACE types (0, 1, 2, or 3+) reported by an individual with FI. All models were adjusted for income, education, smoking, and alcohol consumption in sensitivity analysis.

RESULTS

Individuals exposed to ACEs had elevated levels of FI (mean = 0.13, SD = 0.09) than those unexposed, with the largest difference observed for neglect (B [95% CI]: 0.05 [0.04, 0.06]) and the smallest for parental death and divorce (0.015 [0.01,0.02]). The ACE count was associated with frailty in a graded manner, with the FI difference reaching 0.04 [0.037, 0.044] for participants exposed to 3+ ACE types. The association between ACEs and frailty tended to be stronger for women than men and for men aged 45-64 years than older men.

CONCLUSIONS

Our study supports previous studies showing that exposure to ACEs is associated with frailty in adults. Our findings suggest that screening for ACEs involving childhood maltreatment may be useful for identifying individuals at risk of frailty and prevention of ACEs may have long-term benefits for healthy aging.

Symptoms of major depressive disorder during the COVID-19 pandemic: results from a representative sample of the Canadian population

INTRODUCTION

Since the outbreak of COVID-19, numerous studies from around the world have reported declines in mental health. However, most of these studies were of low-to-moderate quality and many were based on convenience samples or used mental health measures with low validity, or both. Consequently, it has been difficult to draw conclusions.

METHODS

Both the 2020 Survey on COVID-19 and Mental Health (SCMH) and the Canadian Community Health Survey (CCHS) (2015-2019) used the Patient Health Questionnaire-9 to screen for major depressive disorder (MDD) in adults aged 18 or older. The prevalence of MDD was compared between the SCMH and the CCHS. Risk and protective factors for MDD in the SCMH were examined using bivariate and logistic regression analyses.

RESULTS

Based on SCMH data, 15.2% (95% CI: 14.2-16.2) of Canadians screened positive for MDD. The prevalence of MDD was more than two times higher in the SCMH (during COVID-19) than in the CCHS (predating COVID-19). In bivariate analysis, Canadians reporting five or more COVID-19-related risk factors were close to 30 times more likely to have MDD than those reporting no risk factors. Mastery and a sense of community belonging were protective factors for MDD.

CONCLUSION

After remaining stable for two decades, the prevalence of depression among Canadians increased substantially with the onset of COVID-19. Ongoing monitoring of this common condition associated with major morbidity is vital to determine if elevated levels of MDD persist as we progress through and beyond future waves of COVID-19.

The trajectories of depressive symptoms among working adults during the COVID-19 pandemic: a longitudinal analysis of the InHamilton COVID-19 study

Background

Longitudinal studies examining the impact of changes in COVID-19 pandemic-related stressors and experiences, and coping styles on the mental health trajectory of employed individuals during the lockdown are limited. The study examined the mental health trajectories of a sample of employed adults in Hamilton, Ontario during the initial lockdown and after the re-opening following the first wave in Canada. Further, this study also identified the pandemic-related stressors and coping strategies associated with changes in depressive symptoms in employed adults during the COVID-19 pandemic.

Methods

The InHamilton COVID-19 longitudinal study involved 579 employees aged 22–88 years from a large public university in an urban area of Hamilton, Ontario at baseline (April 2020). Participants were followed monthly with 6 waves of data collected between April and November 2020. A growth mixture modeling approach was used to identify distinct groups of adults who followed a similar pattern of depressive symptoms over time and to describe the longitudinal change in the outcome within and among the identified sub-groups.

Results

Our results showed two distinct trajectories of change with 66.2% of participants displaying low-consistent patterns of depressive symptoms, and 33.8% of participants displaying high-increasing depressive symptom patterns. COVID-19 pandemic-related experiences including health concerns, caregiving burden, and lack of access to resources were associated with worsening of the depressive symptom trajectories. Frequent use of dysfunctional coping strategies and less frequent use of emotion-focused coping strategies were associated with the high and increasing depressive symptom pattern.

Conclusions

The negative mental health impacts of the COVID-19 pandemic are specific to subgroups within the population and stressors may persist and worsen over time. Providing access to evidence-informed approaches that foster adaptive coping, alleviate the depressive symptoms, and promote the mental health of working adults is critical.

Association of soluble ST2 and right ventricular dysfunction with mortality in chronic hemodialysis patients

Background

End stage kidney disease (ESKD), is a triggering and facilitating factor for cardiac remodelling (i.e., morphologic hypertrophy and/or dilatation associated with deterioration of systolic and/or diastolic function) that contribute to heart failure (HF). RV dysfunction (RVD) has been demonstrated to predict mortality in ESKD patients.

Purpose

The present study aimed to investigate the potential associations between RVD and circulating biomarkers of myocardial inflammation and fibrosis with all-cause mortality in HD patients.

Method

We performed a retrospective single-centre cohort study of prevalent patients admitted in a chronic HD program for more than 3 months. Clinical characteristics and echocardiographic parameters were assessed in all patients. Pre-dialysis blood samples for measurement of inflammatory (e.g., C reactive protein, interleukin-1, interleukin-18) and fibrotic (e.g., soluble suppression of tumorigenesis-2 [sST2], galectin-3, C-terminal pro-peptide of procollagen type I and N-terminal pro-peptide of procollagen type III) biomarkers were collected. RVD was defined using tricuspid annular plane systolic excursion (TAPSE) &lt;1.7 cm or pulsed Doppler peak annular velocity (S') &lt;9.5 cm/s. The ability of sST2 to discriminate between mortality was assessed using AuROC curve.

Results

We enrolled forty-eight patients, mean patients age was 74 (64 – 79)years, and 62.5% were males. 95.8% of the patients had high blood pressure, and at least 70.8% had HF criteria. About 52.1% of the patients were on OnLine HDF. Regarding the echocardiogram parameters, 56.3% had no functional heart disease, 10.4% had LVD (LVEF ≤45% and diastolic dysfunction ≥ grade 2), and 33.3% had RVD (TAPSE &lt;17mm and/or S'&lt;9.5cm/s), with or without LVD. Mortality was higher 45.5% (log-rank, p=0.003) in patients with RVD as diagnosed by S' than in patients without RVD. No difference in mortality was observed for RVD defined by TAPSE. There were no differences in the morphology and function parameters of the left ventricle between patients with and without RVD. From all biomarkers measured only sST2 was associated with RVD. Indeed, an age- and sex-adjusted analyses showed that doubling of sST2 was inversely associated with a decreased in S' (estimate = −2.03, 95% CI [−3.04 to −1.00] cm/s; P=0.002). Mortality was increased in patients with sST2 ≥40.45 ng/mL compared to patients with sST2 &lt;40.45 ng/mL (66.7% vs. 18.9%, log-rank; p=0.004).

Conclusion

This preliminary data would suggest that patients on chronic HD, circulating levels of sST2 were independently associated with RVD. In addition, elevated sST2 levels and RVD were associated with increased all-cause mortality. The myocardial pro-remodelling effect of sST2 in HD patients with RVD warrants further investigation.

Impact of previous cardiac conditions in prognosis and clinical management of patient with COVID-19 infection

Background

Recent studies suggest a higher mortality rate because of COVID-19 in patients with previous cardiac conditions compared to those without. Given the limited resources of intensive care units (ICU) during the pandemic outbreak, this fact has important implications.

Purpose

The main purpose of this study was to compare the 30-day mortality of the COVID-19 infection in patients with and without previous cardiac conditions. The secondary end point was to assess the differences in clinical severity of the infection (as development of Acute Respiratory Distress Syndrome – ARDS) and ICU admission amongst these patients.

Methods

A total of 1708 consecutive patients were prospectively included. The inclusion criteria were: a confirmed positive diagnosis of COVID-19 infection by PCR and being admitted to our centre between 18th and 23rd March 2020 and 22nd August and 9th January 2021. Patients were classified in two groups according to the presence of previous cardiac conditions (defined as previous history of myocardial infarction, heart failure and atrial fibrillation). Other comorbidities were extensively explored and Charlson Comorbidity Index was calculated. A propensity-score matching was performed and 145 patients with previous cardiac conditions were matched with 145 patients without.

Results

The group of patients with a previous cardiac condition included 421 patients (24.6%). The crude analysis showed a higher 30-day mortality rate among patients with previous cardiac affections (35.6% vs. 14.6%, p&lt;0.001). They were also less likely to be admitted to the ICU (9.8% vs. 6.2%, p=0.022) and had a higher prevalence ARDS (48.9% vs. 33.9%, p&lt;0.001). In the matched cohort, there were no significant differences between both groups regarding mortality (24.8% in the group of patients with previous cardiac conditions vs. 31.0%, p=0.272) nor ARDS prevalence (50.3% vs. 53.1%, p=0.655). There was a trend toward patients with previous cardiac conditions to be less likely to be admitted to the ICU (4.8% vs. 9.7%, p=0.090).

Conclusions

Patients with a personal history of previous cardiac conditions were less likely to be admitted to the ICU. However, our results show that when comparing cohorts with similar comorbidity burden, a previous cardiopathy “per se” does not significantly increase the risk of death in patients with a concomitant COVID infection.

Endotrophin is significantly associated with disease severity and increased risk of adverse outcome in HFpEF but not in HFrEF patients

Introduction

The global burden of heart failure (HF), with either reduced (HFrEF) or preserved (HFpEF) ejection fraction, has increased dramatically over the past years, and HFpEF is projected to become the dominant type of HF. Fibrogenesis, promoted by fibroblast activity, plays an important role in the pathology of HF regardless of subtype, causing impaired cardiac function. Endotrophin is a bioactive molecule released from collagen type VI during its maturation, and it is a marker of fibroblast activity. The aim of this post-hoc analysis was to confirm the previously observed prognostic potential of endotrophin (measured by PRO-C6) for adverse outcome in HFpEF and to test its prognostic abilities in HFrEF.

Methods

234 patients with hypertension and either HFrEF (30.3%) or HFpEF (69.7%) were included for analysis. 43.2% were NYHA Class II, 52.5% NYHA Class III and 2.5% NYHA Class IV. 53.4% of patients had a previous history of atrial fibrillation. The cohort did not include diabetic patients. Cardiac function was assessed by echocardiography and standard clinical measures, including left ventricle ejection fraction (EF), blood pressure (BP) and measurement of N-terminal natriuretic brain-peptide (NT-proBNP). Circulating endotrophin was quantified at baseline in serum by means of an enzyme-linked immunosorbent assay, PRO-C6.

Results

PRO-C6 levels increased significantly with disease severity in HFpEF patients (NYHA Class III vs II, p=0.0003), but not in HFrEF patients (NYHA Class III vs II, p=0.33). In HFpEF patients, PRO-C6 was able to discriminate between patients that were hospitalized for HF (AUC=0.69, p&lt;0.001), died from cardiovascular (CV) causes (AUC=0.74, p&lt;0.001), or by any other cause (AUC=0.73, p&lt;0.001). PRO-C6 was not associated with none of these outcomes in HFrEF patients (AUC=0.56, p=0.42; AUC=0.53, p=0.73; AUC=0.56, p=0.53, respectively). Adding PRO-C6 to a risk prediction model containing age, sex, body mass index and systolic BP significantly increased the discriminatory power of the model for mortality (deltaAUC=0.037, p=0.04). When looking at patients stratified in PRO-C6 tertiles, patients in the upper tertile had a significantly higher risk of mortality (p&lt;0.0001, hazard ratios 3 vs 1=4.1, 3 vs 2=3.5, respectively) and HF hospitalization (p&lt;0.0001, hazard ratio 3 vs 1=4.4, 3 vs 2=1.6, respectively) compared to tertiles 1 and 2.

Conclusion

In this population of hypertensive HF patients, circulating endotrophin, measured by PRO-C6, was increased with increasing disease severity, and associated with a higher risk of adverse outcome in HFpEF, but not in HFrEF patients. The data presented here suggest a potential role of endotrophin in HFpEF pathophysiology and further underline the differences between HFpEF and HFrEF. These data confirm previous observations, and strengthen the usefulness of endotrophin, measured by the PRO-C6 biomarker, as a prognostic tool aiding in assessment of HFpEF patients.

Prognostic factors at admission on patients with cancer and COVID-19: Analysis of HOPE registry data

Background

Previous works seem to agree in the higher mortality of cancer patients with COVID-19. Identifying potential prognostic factors upon admission could help identify patients with a poor prognosis.

Methods

We aimed to explore the characteristics and evolution of COVID-19 cancer patients admitted to hospital in a multicenter international registry (HOPE COVID-19).

Our primary objective is to define those characteristics that allow us to identify cancer patients with a worse prognosis (mortality within 30 days after the diagnosis of COVID-19).

Results

5838 patients have been collected in this registry, of whom 770 had cancer among their antecedents. In hospital mortality reached 258 patients (33.51%). The median was 75 years (65–82). Regarding the distribution by sex, 34.55% of the patients (266/770) were women.

The distribution by type of cancer: genitourinary 238/745 (31.95%), digestive 124/745 (16.54%), hematologic 95/745 (12.75%).

In multivariate regression analysis, factors that are independently associated with mortality at admission are: renal impairment (OR 3.45, CI 97.5% 1.85–6.58), heart disease (2.32, 1.47–3.66), liver disease (4.69, 1.94–11.62), partial dependence (2.41, 1.34–4.33), total dependence (7.21, 2.60–21.82), fatigue (1.84, 1.16–2.93), arthromialgias (0.45, 0.26–0.78), SatO2 < 92% (4.58, 2.97–7.17), elevated LDH (2.61, 1.51–4.69) and abnormal decreased Blood Pressure (3.57, 1.81–7.15). Analitical parameters are also significant altered.

Conclusion

In patients with cancer from the HOPE registry, 30-day mortality from any cause is high and is associated with easily identifiable clinical factors upon arrival at the hospital. Identifying these patients can help initiate more intensive treatments from the start and evaluate the prognosis of these patients.

Effects of household chaos and parental responsiveness on child executive functions: a novel, multi-method approach

Background

Executive functions can be adversely affected by contextual risks in the home environment including chaos and parenting challenges. Furthermore, household chaos negatively influences parenting practices. Few studies, however, have examined the role of parenting in the association between household chaos and child executive functions.

Methods

Using a sample of 128 school-aged children (mean = 61.9 months, SD = 2.0, range 58–68 months) and their mothers, the present study examined direct and indirect effects (via parental responsiveness) of household chaos on child executive functioning. Multi-measures were used including performance-based assessments, behavioural observations, questionnaires, and video-home tours.

Results

Household chaos had both a direct effect on child executive functions (β = − .31, 95% CI [− .58, − .04]) and an indirect effect (β = − .05, 95% [− .13, − .01]) via parental responsiveness. Further, the indirect effect was only significant for household instability.

Conclusion

These findings indicate that parental responsiveness may be compromised by household chaos, with implications for the executive functions of school-aged children. Preventative strategies are needed to improve the stability in the home and strengthen parenting practices.

Zinc-chelating postsynaptic density-95 N-terminus impairs its palmitoyl modification

Chemical synaptic transmission represents the most sophisticated dynamic process and is highly regulated with optimized neurotransmitter balance. Imbalanced transmitters can lead to transmission impairments, for example, intracellular zinc accumulation is a hallmark of degenerating neurons. However, the underlying mechanisms remain elusive. Postsynaptic density protein-95 (PSD-95) is a primary postsynaptic membrane-associated protein and the major scaffolding component in the excitatory postsynaptic densities, which performs substantial functions in synaptic development and maturation. Its membrane association induced by palmitoylation contributes largely to its regulatory functions at postsynaptic sites. Unlike other structural domains in PSD-95, the N-terminal region (PSD-95NT) is flexible and interacts with various targets, which modulates its palmitoylation of two cysteines (C3/C5) and glutamate receptor distributions in postsynaptic densities. PSD-95NT contains a putative zinc-binding motif (C2H2) with undiscovered functions. This study is the first effort to investigate the interaction between Zn²⁺ and PSD-95NT. The NMR titration of ¹⁵ N-labeled PSD-95NT by ZnCl₂ was performed and demonstrated Zn²⁺ binds to PSD-95NT with a binding affinity (K_d ) in the micromolar range. The zinc binding was confirmed by fluorescence and mutagenesis assays, indicating two cysteines and two histidines (H24, H28) are critical residues for the binding. These results suggested the concentration-dependent zinc binding is likely to influence PSD-95 palmitoylation since the binding site overlaps the palmitoylation sites, which was verified by the mimic PSD-95 palmitoyl modification and intact cell palmitoylation assays. This study reveals zinc as a novel modulator for PSD-95 postsynaptic membrane association by chelating its N-terminal region, indicative of its importance in postsynaptic signaling.

The Emerging Role of Nutraceuticals and Phytochemicals in the Prevention and Treatment of Alzheimer's Disease

One of the major challenges of medical sciences has been finding a reliable compound for the pharmacological treatment of Alzheimer's disease (AD). As most of the drugs directed to a variety of targets have failed in finding a medical solution, natural products from Ayurvedic medicine or nutraceutical compounds emerge as a viable preventive therapeutics' pathway. Considering that AD is a multifactorial disease, nutraceutical compounds offer the advantage of a multitarget approach, tagging different molecular sites in the human brain, as compared with the single-target activity of most of the drugs used for AD treatment. We review in-depth important medicinal plants that have been already investigated for therapeutic uses against AD, focusing on a diversity of pharmacological actions. These targets include inhibition of acetylcholinesterase, β-amyloid senile plaques, oxidation products, inflammatory pathways, specific brain receptors, etc., and pharmacological actions so diverse as anti-inflammatory, memory enhancement, nootropic effects, glutamate excitotoxicity, anti-depressants, and antioxidants. In addition, we also discuss the activity of nutraceutical compounds and phytopharmaceuticals formulae, mainly directed to tau protein aggregates mechanisms of action. These include compounds such as curcumin, resveratrol, epigallocatechin-3-gallate, morin, delphinidins, quercetin, luteolin, oleocanthal, and meganatural-az and other phytochemicals such as huperzine A, limonoids, azaphilones, and aged garlic extract. Finally, we revise the nutraceutical formulae BrainUp-10 composed of Andean shilajit and B-complex vitamins, with memory enhancement activity and the control of neuropsychiatric distress in AD patients. This integrated view on nutraceutical opens a new pathway for future investigations and clinical trials that are likely to render some results based on medical evidence.
