Evaluating In-home Assistive Technology for Dementia Caregivers.

OBJECTIVES: Dementia caregivers (CGs) are at heightened risk for developing problems with anxiety and depression. Much attention has been directed toward developing and deploying interventions designed to protect CG health, but few have been supported by rigorous empirical evidence. Technology-based interventions that are effective, scalable, and do not add greatly to the CG burden are of particular interest. METHODS: We conducted a nine-month randomized controlled trial in 63 homes evaluating People Power Caregiver (PPCg), a system of sensors in the home connected to cloud-based software that alerts CGs about worrisome deviations from normal patterns (e.g., falls, wandering). RESULTS: CGs in the active condition had significantly less anxiety than those in the control condition at the six-month assessment. Greater anxiety reduction in the active condition at the six-month assessment was associated with greater interaction with PPCg via SMS text messages. There were no differences in anxiety at the three-month or nine-month assessments or in depression at any assessment. CONCLUSIONS: PPCg shows promise for reducing anxiety associated with caring for a =person with dementia. CLINICAL IMPLICATIONS: Technology-based interventions can help reduce CG anxiety, a major adverse consequence of caregiving that may be difficult to treat due to other demands on caregiver time and energy.

Are sodium-glucose co-transporter-2 inhibitors associated with improved outcomes in diabetic patients admitted to intensive care units with septic shock?

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been shown to reduce organ dysfunction in renal and cardiovascular disease. There are limited data on the role of SGLT2i in acute organ dysfunction. We conducted a study to assess the effect of SGLT2i taken prior to intensive care unit (ICU) admission in diabetic patients admitted with septic shock. METHODS: This retrospective cohort study used electronic medical records and included diabetic patients admitted to the ICU with septic shock. We compared diabetic patients on SGLT2i to those who were not on SGLT2i prior to admission. The primary outcome was in-hospital mortality, and secondary outcomes included hospital and ICU length of stay, use of renal replacement therapy, and 28- and 90-day mortality. RESULTS: A total of 98 diabetic patients was included in the study, 36 in the SGLT2i group and 62 in the non-SGLT2i group. The Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation III scores were similar in the groups. Inpatient mortality was significantly lower in the SGLT2i group (5.6% vs. 27.4%, P=0.008). There was no significant difference in secondary outcomes. CONCLUSIONS: Our study found that diabetic patients on SGLT2i prior to hospitalization who were admitted to the ICU with septic shock had lower inpatient mortality compared to patients not on SGLT2i.

A US-Based Multicenter Retrospective Report of Perioperative Anaphylaxis, 2010-2021.

BACKGROUND: US-based perioperative anaphylaxis (POA) studies are limited to single-center experiences. A recent report found that a serum acute tryptase (sAT) >9.8 ng/mL or mast cell activation (MCA) can predict POA causal agent identification. Urinary mast cell mediator metabolites (uMC) have not been studied in POA. OBJECTIVE: To analyze the epidemiologic data of POA, to determine if sAT or MCA can predict suspected causal agent identification, and to evaluate uMC utility in POA. METHODS: This study is a retrospective multicenter review of POA cases that were subcategorized by suspected causal agent identification status. sAT, MCA (defined as sAT >2 + 1.2 × serum baseline tryptase), and uMC (N-methylhistamine [N-MH], 11ß-prostaglandin-F2α [11ß-PGF2α], leukotriene E4 [LTE4]) were recorded. RESULTS: Of 100 patients (mean age 52 [standard deviation 17] years, 94% adult, 50% female, 90% White, and 2% Hispanic) with POA, 73% had an sAT available, 41% had MCA, 16% had uMC available, and 50% had an identifiable suspected cause. POA cases with an identifiable suspected cause had a positive MCA status (100% vs 78%; P = .01) compared with POA with an unidentifiable cause. An elevated median sAT did not predict causal agent identification. Positive uMC were not associated with suspected causal agent identification during POA. Patients with positive uMC had a higher median sAT (30 vs 6.45 ng/mL; P = .001) and MCA status (96% vs 12%; P = .001) compared with negative uMC patients. Patients with POA had an elevated acute/baseline uMC ratios: 11ß-PGF2α ratio > 1.6, N-MH ratio >1.7, and LTE4 ratio >1.8. CONCLUSIONS: The presence of MCA in POA is associated with suspected causal agent identification. Positive uMC possibly correlate with a higher sAT level and MCA status but require further study. The authors suggest applying an acute/baseline uMC ratio (11ß-PGF2α ratio >1.6, N-MH ratio >1.7, and LTE4 ratio >1.87) in patients with POA for MCA when a tryptase level is inconclusive during POA evaluations.

Assessing knowledge gaps and educational needs in urine drug test interpretation among health care professionals.

OBJECTIVES: Urine drug testing (UDT) is a critical tool used in medical, forensic, and occupational settings, but interpreting results can be challenging. We performed a study to assess the ability of health care professionals to interpret UDT results accurately. METHODS: In total, 911 clinical and laboratory professionals in the United States and Canada responded to a survey with questions gauging expertise in UDT interpretation. Responses were analyzed to identify knowledge gaps. RESULTS: Toxicologists and laboratory PhD scientists performed well, with means of 4.82 and 4.63 questions answered correctly (out of 6 possible), respectively. Physicians specializing in pathology, emergency medicine, primary care, and internal medicine, however, displayed concerning knowledge gaps, as did laboratorians with nondoctoral degrees. Experience and training correlated with interpretation accuracy. Identification of simulated compliance as well as understanding opioid exposure, metabolism, and immunoassay cross-reactivity were among the most clinically significant knowledge gaps. More than 30% of survey respondents indicated that they would seek UDT information from the internet or peers rather than clinical or laboratory experts. CONCLUSIONS: The study highlighted the need for targeted education and better collaboration between clinical and laboratory experts and other health care professionals to ensure that when physicians order UDT, they can accurately interpret results and reduce harm.

Pronoun Use among Caregivers of People Living with Dementia: Associations with Dementia Severity Using Text Analysis of a Natural Language Sample.

Introduction: Family caregivers of persons living with dementia (PLWDs) have extensive social, physical, emotional, and financial responsibilities. However, less is known about the relationship and interpersonal connection between caregivers and PLWDs. We examined caregiver pronoun use, as an index of the connection between the caregiver and PLWD and its associations with the caregiver's and PLWD's health and well-being. Methods: Caregivers of PLWDs (N = 320) were asked to describe a recent time they felt connected to the PLWD in their care. Responses were transcribed and coded to quantify pronoun use by category (we-pronouns, I-pronouns, and they-pronouns). Caregivers also reported on their depression, burden, and the PLWD's dementia severity and marital satisfaction. Sixty-eight caregivers repeated the same survey 24 months after the initial survey. Results: Caregivers used less we-pronouns when the PLWD's dementia was more severe, at both timepoints. Spousal caregivers used more we-pronouns and less I- and they-pronouns than nonspousal caregivers. There was an interaction between spousal relationship and dementia severity, such that spousal caregivers exhibited a stronger negative association between dementia severity and we-pronoun use. There were no associations between pronoun category and caregiver burden or depression. Discussion: Caregivers may feel increasingly disconnected from the PLWD as their dementia becomes more severe, as reflected by less we-pronoun usage. This study highlights the opportunity to explore relationship connection through text analysis.

Adaptability and cohesion in youth at clinical high-risk for psychosis: A multi-informant approach.

BACKGROUND: Families can play a critical role in the development of psychosis. Adaptability (i.e., flexibility) and cohesion (i.e., emotional bonding) are important markers of family functioning, but have rarely been studied in youth at clinical high risk for developing psychosis (CHR), especially not from a multi-informant perspective. METHODS: The current study examined adaptability and cohesion (using youth and mother reports) and clinical symptoms (in youth) among 75 youth at CHR and their mothers (N = 48) and 79 matched healthy controls and their mothers (N = 42). RESULTS: Findings showed that (1) youth at CHR and their mothers reported lower adaptability and cohesion than their healthy control counterparts. (2) All youth reported lower adaptability than mothers, but only youth at CHR (not control youth) reported lower cohesion than their mothers. (3) There were no significant links between CHR youth and mother reports of adaptability and cohesion and clinical symptoms. CONCLUSIONS: Findings support existing literature that families with a youth at CHR are at risk for poorer functioning and demonstrate pronounced youth-mother discrepancies with youth at CHR (but not controls) reporting lower emotional bonding than their mothers. Future studies may further probe multi-informant perspectives of family environment as a clinical marker in the clinical high risk state.

Coping with family stress in individuals at clinical high-risk for psychosis.

BACKGROUND: Despite the long-emphasized role of the family environment in the schizophrenia literature, coping with family stress has been neglected in research on the psychosis risk period. METHODS: The sample consisted of 75 youth at clinical high-risk (CHR) for psychosis and 79 matched healthy controls who reported on their use of engagement and disengagement coping strategies in response to stress with parents and perceived social support (i.e., advice availability, family support and strain). Participants were also assessed for clinical symptoms. RESULTS: Individuals at CHR reported similar levels of engagement strategies (e.g., emotion regulation, positive thinking) and more frequent use of disengagement strategies (e.g., avoidance, denial) compared to healthy controls. In individuals at CHR (as well as healthy controls), greater use of engagement strategies predicted greater perceptions of availability of advice support, whereas greater employment of disengagement strategies predicted lower perceived social support from the family and greater family strain. In individuals at CHR (as well as healthy controls), engagement strategies were not linked to any clinical outcomes, whereas disengagement strategies were closely tied to anxiety and depression (but not psychosis symptoms in individuals at CHR). CONCLUSIONS: Individuals at CHR appeared to engage the same amount as controls, but disengage more often when coping with family stress; this pattern was linked to perceptions of social support and tied to a putative family environment as well as clinical phenomenology. The findings have implications for targeting interventions for CHR populations during a vulnerable period for stress and social change.

Trait emotional experience in individuals with schizophrenia and youth at clinical high risk for psychosis.

BACKGROUND: Disturbances in trait emotions are a predominant feature in schizophrenia. However, less is known about (a) differences in trait emotion across phases of the illness such as the clinical high-risk (CHR) phase and (b) whether abnormalities in trait emotion that are associated with negative symptoms are driven by primary (i.e. idiopathic) or secondary (e.g. depression, anxiety) factors. AIMS: To examine profiles of trait affective disturbance and their clinical correlates in individuals with schizophrenia and individuals at CHR for psychosis. METHOD: In two studies (sample 1: 56 out-patients diagnosed with schizophrenia and 34 demographically matched individuals without schizophrenia (controls); sample 2: 50 individuals at CHR and 56 individuals not at CHR (controls)), participants completed self-report trait positive affect and negative affect questionnaires, clinical symptom interviews (positive, negative, disorganised, depression, anxiety) and community-based functional outcome measures. RESULTS: Both clinical groups reported lower levels of positive affect (specific to joy among individuals with schizophrenia) and higher levels of negative affect compared with controls. For individuals with schizophrenia, links were found between positive affect and negative symptoms (which remained after controlling for secondary factors) and between negative affect and positive symptoms. For individuals at CHR, links were found between both affect dimensions and both types of symptom (which were largely accounted for by secondary factors). CONCLUSIONS: Both clinical groups showed some evidence of reduced trait positive affect and elevated trait negative affect, suggesting that increasing trait positive affect and reducing trait negative affect is an important treatment goal across both populations. Clinical correlates of these emotional abnormalities were more integrally linked to clinical symptoms in individuals with schizophrenia and more closely linked to secondary influences such as depression and anxiety in individuals at CHR. DECLARATION OF INTEREST: None.

An insecure base: Attachment style and orienting response to positive stimuli.

In adults as in infants, psychological attachment to close others provides a "secure base" for exploration and pursuit of opportunities. Insecure attachment is likely to interfere with this function. The present study examined the association of individual differences in adult attachment style with peripheral physiological measures of automatic orienting to several kinds of positive, rewarding stimuli. Attachment style was largely unrelated to extent of heart rate deceleration in response to the appearance of positive emotion-eliciting images. However, attachment avoidance was associated with reduced skin conductance responding to the onset of several kinds of positive stimuli. These findings suggest that working models of relationships with close others have complex implications for the early stages of responding to opportunities for reward presented by the environment.
