Identifying Targets to Improve the Management of Severe Hypertension in Pregnancy and Postpartum.

OBJECTIVES: To (1) define quality indicators, (2) describe care gaps, and (3) identify process issues in severe hypertension (sustained systolic blood pressure [BP] ≥160 mm Hg or diastolic BP ≥110 mm Hg) management at our tertiary care centre. METHODS: Pregnant and postpartum persons diagnosed with a hypertensive disorder of pregnancy from 2018 to 2019 were identified. A retrospective cohort of patients with severe hypertension was constructed, and data were collected through chart review. Severe hypertension management was assessed according to defined quality indicators. Clinical characteristics were compared between participants with and without time-to-target BP within 60 minutes. Process issues were examined for each severe hypertension occurrence. RESULTS: Of 608 participants with a hypertensive disorder of pregnancy, 90 (15%) experienced severe hypertension. Median time-to-target BP was 76 minutes (interquartile range 47-123 minutes), and target BP (<155/105 mm Hg) was achieved within 60 minutes in 31/90 (34%) participants. Appropriate antihypertensives for severe hypertension were used in 55/90 (61%), and time-to-treatment initiation was within 30 minutes in 42/54 (78%). Chronic hypertension and oral labetalol use were associated with delays in achieving target BP. Process issues related to severe hypertension management included inappropriate treatment (n = 35/90; 39%), failure to recognize severe hypertension as an emergency (n = 21/90; 23%), and delayed treatment initiation (n = 12/54; 22%). CONCLUSION: We defined quality indicators for severe hypertension management. Time-to-target BP within 60 minutes was achieved in a minority of patients, and chronic hypertension was associated with delayed severe hypertension resolution. Process issues in severe hypertension management were described.

Perceived Injustice as a Determinant of the Severity of Post-traumatic Stress Symptoms Following Occupational Injury.

BACKGROUND: The present study assessed the role of perceived injustice in the experience and persistence of post-traumatic stress symptoms (PTSS) following work-related musculoskeletal injury. METHODS: The study sample consisted of 187 individuals who were absent from work as a result of a musculoskeletal injury. Participants completed measures of pain severity, perceived injustice, catastrophic thinking, post-traumatic stress symptoms, and disability on three occasions at three-week intervals. RESULTS: Consistent with previous research, correlational analyses revealed significant cross-sectional relations between pain and PTSS, and between perceived injustice and PTSS. Regression analysis on baseline data revealed that perceived injustice contributed significant variance to the prediction of PTSS, beyond the variance accounted for by pain severity and catastrophic thinking. Sequential analyses provided support for a bi-directional relation between perceived injustice and PTSS. Cross-lagged regression analyses showed that early changes in perceived injustice predicted later changes in PTSS and early changes in PTSS predicted later changes in perceived injustice. CONCLUSIONS: Possible linkages between perceived injustice and PTSS are discussed. The development of effective intervention techniques for targeting perceptions of injustice might be important for promoting recovery of PTSS consequent to musculoskeletal injury.

Qualitative Examination of the Experience of Perceived Injustice Following Disabling Occupational Injury.

PURPOSE: The primary objective of this study was to explore individuals' perspectives on the factors, situations or events that contributed to their perceptions of injustice following occupational injury. MATERIALS AND METHODS: The study sample consisted of 30 participants (18 women, 12 men) who had submitted a time-loss claim for a work-related musculoskeletal injury. Participants with elevated scores on a measure of perceived injustice were interviewed about the factors that contributed to their sense of injustice. A thematic analysis was conducted to identify the broad classes of situations or events that participants experienced as unjust in the weeks following occupational injury. RESULTS: Three dominant themes emerged from the interviews: (1) Invalidation, (2) Undeserved suffering and (3) Blame. Inductively derived subthemes reflected specific dimensions of post-injury experiences that contributed to participants' sense of injustice. CONCLUSIONS: Given that suffering and invalidating communication are potentially modifiable factors, there are grounds for optimism that intervention approaches can be developed to prevent or reduce perceptions of injustice in the aftermath of debilitating injury. The development of intervention approaches that are effective in preventing or reducing perceptions of injustice holds promise of contributing to more positive recovery outcomes in individuals who have sustained debilitating work injuries.

Synchronous Health Care Delivery for the Optimization of Cardiovascular and Renal Care in Patients with Type 2 Diabetes.

PURPOSE OF REVIEW: The current care model of type 2 diabetes (T2D) and its complications appears to be "asynchronous" with patient care divided by specialty. This model is associated with low use of guideline-directed medical therapies. RECENT FINDINGS: The use of integrated care models has been well described in the management of patients with T2D; this usually includes an endocrinologist coupled with a nutritionist and nurse. However, physician-based care models are largely "asynchronous," whereby the patient requires multiple different siloed specialties to manage their health care. To date, there has been limited exploration of synchronous care delivery, i.e., whereby multi-comorbid patients with T2D are seen simultaneously by health care providers from endocrinology, cardiology, and nephrology to optimize use of guideline-directed medical therapies (GDMT). Given the rising complexity of patients with T2D, further research is needed on the role of synchronous health care delivery in optimizing the use of GDMT and improving patient outcomes.

The Prospective Prognostic Value of Biopsychosocial Indices of Sensitivity to Physical Activity Among People With Back Pain.

OBJECTIVES: Many people living with musculoskeletal pain conditions experience a range of negative biopsychosocial responses to physical activity, referred to as increased sensitivity to physical activity (SPA), that may undermine successful rehabilitation. This exploratory study aims to provide the first prospective analysis of the potential prognostic value of 3 biopsychosocial indices of SPA in relation to rehabilitation outcomes. This study also aimed to shed light on the cross-sectional interrelationships between these 3 biopsychosocial indices of SPA. MATERIALS AND METHODS: Adults with back pain were evaluated upon starting physical therapy and then again 3 months later. The initial testing session consisted of self-reported pain-related questionnaires and assessment of activity-related changes in pressure pain thresholds (SPA-Sensory), pain intensity ratings (SPA-Pain), and situational catastrophizing (SPA-Psych). The 3-month follow-up consisted of self-reported disability and pain questionnaires. Correlational and hierarchical linear regression analyses were conducted. RESULTS: A total of 97 participants completed both the initial visit and 3-month follow-up. The SPA-Pain index and the SPA-Psych index were significantly intercorrelated, but neither were correlated with the SPA-Sensory index. The SPA-Sensory index was not correlated with outcomes. The SPA-Pain index was correlated only with cross-sectional disability and pain outcomes. The SPA-Psych index was the only SPA index significantly correlated with outcomes both cross-sectionally and at 3-month follow-up. After controlling for baseline pain/disability and pain catastrophizing, SPA-Psych was no longer a significant prognostic factor for pain, but remained a significant prognostic factor for disability at 3-month follow-up (ß=0.272, t=2.674, P=0.008, R2 Δ=5.60%). DISCUSSION: This study highlights the importance of conceptualizing and measuring SPA as a biopsychosocial (rather than unidimensional) construct and points toward the added prognostic value of this construct. Implications for future research and practice are discussed.

Audiovisual integration capacity modulates as a function of illusory visual contours, visual display circumference, and sound type.

Research into the capacity of audiovisual integration has previously assessed whether capacity is strictly limited to a single item, or whether it can exceed one item under certain environmental conditions. More recently, investigations have turned to examining the effects of various stimulus factors on capacity. Across two experiments, we looked at a number of factors that were expected to play a modulatory role on capacity. Experiment 1 deployed a manipulation of illusory polygons, revealing an increase in audiovisual capacity, even in an absence of visual connections. This demonstrates that exceeding the capacity of 1 does not only represent a functional increase in the binding of a singular, complex visual object, but that it can also represent binding of multiple simpler objects. Findings also support the hypothesis that capacity modulates quantitatively, but not qualitatively, with respect to speed of presentation. Experiment 2 examined the effects of different sound types (sine tones or white noise) and of different spatial visual field sizes on the capacity of audiovisual integration. The results indicate that capacity is maximized when stimuli are presented in a smaller circle (7.5°) if alongside a sine tone, and when presented in a larger circle (18.5°) alongside white noise. These results suggest that audiovisual integration capacity is dependent on the combination of sound type and visual spatial field size. The combination of these results reveal additional phenomenological features of the capacity of audiovisual integration, and provides impetus for further research into applications of the findings.
