Evaluating the Performance of the Primary Care Posttraumatic Stress Disorder Screen for DSM-5 (PC-PTSD-5) in a Trauma-Exposed, Socioeconomically Vulnerable Patient Population

The properties and utility of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) remain unstudied in community-based populations. This study evaluates the performance of the PC-PTSD-5 to determine whether it can be used as a brief alternative to the PTSD Checklist for DSM-5 (PCL-5) in a large public hospital in the southeastern United States. Participants (N = 422; 92.7% Black; 85.8% female; Mage = 42.0 years, SDage = 13.4 years) completed the PCL-5 and PC-PTSD-5 after recruitment from medical clinic waiting rooms and admission lists. Using chance-corrected test quality indices and item response theory (IRT) analyses, we determined optimal cut-scores for screening and examined item performance. Approximately 45.0% of the sample screened positive for probable DSM-5 PTSD using the PCL-5. The PC-PTSD-5 demonstrated high internal consistency and strong associations with PCL-5 scores (total, r = .79; items, rs = .51-.61). A cut-score of one was optimally sensitive for screening (κ[1] = .96), and a cut-score of four had the highest quality of probable efficiency (κ[.5] = .66) for detecting self-reported DSM-5 PTSD on the PCL-5. IRT analyses indicated Item 1 (nightmares, intrusive memories) provided the most information, and other items may not be incrementally useful for this sample. Findings provide preliminary support for the use of the PC-PTSD-5 as a brief alternative to the PCL-5 among chronically trauma-exposed patients in the public healthcare setting.

Brief trauma-informed care training to enhance health care providers' knowledge, comfort, and implementation of trauma-informed care in primary care clinics: A pilot effectiveness study

Trauma-informed care (TIC) training may be valuable for patient-facing health care providers within primary care in urban health care settings serving patients with high levels of trauma exposure. This study tested the pilot effectiveness of a clinic-wide TIC initiative to enhance providers' knowledge, comfort in caring for trauma-exposed patients, and implementation of TIC within a primary care clinic of an urban safety net hospital using a single-arm longitudinal within-subjects design. Measures were obtained at baseline (T1), posttraining (T2), 1-month (T3), and 6-months (T4). Twenty-nine providers who completed TIC training were included in study analyses. Twenty-one completed T2 and 14 completed T3 and T4. Knowledge was measured with the Providers' Knowledge Regarding Injury-Related Posttraumatic Stress, comfort with a researcher-generated two-item measure, and TIC implementation with an eight-item binary scale from the Trauma Provider Survey. Repeated-measures general linear model examining within-subjects change over time in knowledge was significant (n = 8; F₃ = 4.74, p = .01, ηp² = .40); the model measuring change in comfort was not significant but trending (n = 9; F₃ = 4.56, p = .06). The model examining change in TIC implementation from T1 to T4 was not significant (n = 14; F3 = 4.32, p = .21). This pilot study demonstrated the preliminary effectiveness of a brief TIC training on improving health care provider knowledge and comfort working with trauma-exposed patients that sustained through 6-months posttraining. The findings indicate that additional support is needed to change behaviors in provider implementation of TIC in primary care clinic settings.

Primary Care Providers' Knowledge, Perceptions, and Practice of Trauma-Informed Care in a Public Health Care Setting

Despite serving patients with especially high rates of trauma exposure and related sequelae, many primary care providers do not receive specialized training in the provision of trauma-informed care (TIC). This study sought to document primary care providers' baseline rates of TIC training and their knowledge, perceptions, and practice of TIC at a large, urban public hospital in the Southeastern United States. Participants (n = 67; 68.7% women; 44.8% white; Mage = 36.7 years, standard deviation [SD]age = 9.8 years) completed an online self-report survey on their TIC training status, trauma-related knowledge, perceptions, and practices, as well as burnout and secondary traumatic stress. Less than half of participants (43.3%) endorsed TIC training exposure. Participants generally had adequate levels of trauma-related knowledge (76.5% of items correct) and favorable perceptions of TIC (endorsed 89.7% of TIC-supportive statements). Most participants (86.6%) endorsed recently using trauma-informed practices, but only 47.8% reported routinely screening for trauma-related disorders. Participants who reported receiving prior TIC training scored better on knowledge items and endorsed recently using more trauma-informed practices than those who did not have training exposure. TIC training status' associations with current screening practices and perceptions of TIC were trending toward significance. TIC training status was not related to burnout, and trained participants reported greater secondary traumatic stress than those without training exposure. Results point to system-wide TIC training as a well-received, translational strategy that can enhance the trauma-informed nature of primary care provision.

Improving Depression Screening in Underserved Populations in a Large Urban Academic Primary Care Center: A Provider-Centered Analysis and Approach

Screening for depression is paramount to identify patients with depression and link them to care, yet only 29% of patients in the primary care center (PCC) were screened for depression in 2016. A baseline survey identified provider barriers to depression screening, including lack of time, support staff, and referral resources. The purpose of this project was to increase depression screening in the PCC using the Patient Health Questionnaire (PHQ-2/9). The authors created an educational program for staff and providers that included referral resources, treatment guidelines, and a decision-support tool in the electronic medical record. A retrospective chart review was performed, from January 2016 to June 2017, to determine the percentage of patients who received annual depression screening. During the program, the PCC saw an increase in depression screening rates. Thus, it is possible to overcome barriers to depression screening in a primary care setting by providing resources and education to clinicians.

Chronic Cutaneous Lupus Erythematosus: Depression Burden and Associated Factors

OBJECTIVES

Depression may occur in up to 30% of individuals with cutaneous lupus erythematosus (CLE), many of whom may also have systemic manifestations. Chronic cutaneous lupus erythematosus (CCLE) conditions are less likely to present systemic involvement than acute and subacute conditions but more often cause permanent scarring and dyspigmentation. However, little is known about depression in those who have CCLE confined to the skin (primary CCLE). As African Americans are at high risk for primary CCLE and depression, we aimed to investigate the prevalence of and explore the risk factors for depression in a population-based cohort of predominantly Black patients with primary CCLE.

METHODS

This was a cross-sectional analysis of a cohort of individuals with a documented diagnosis of primary CCLE, established in metropolitan Atlanta, GA, USA. Participants were recruited from the Centers for Disease Control and Prevention (CDC) population-based Georgia Lupus Registry, multicenter dermatology clinics, community practices, and self-referrals. The Patient-Reported Outcomes Measurement Information System (PROMIS) was used to measure the primary outcome: depressive symptoms. Stand-alone questions were used to assess sociodemographics and healthcare utilization. Emotional, informational, and instrumental support were measured with PROMIS short forms, interpersonal processes of care with the IPC-29 survey, and skin-related quality of life with the Skindex-29+ tool.

RESULTS

Of 106 patients, 92 (86.8%) were female, 91 (85.8%) were Black, 45 (42.9%) were unemployed or disabled, and 28 (26.4%) reported moderate to severe depressive symptoms. Depression severity was lower in patients who were aged ≥ 60 years, were married, or had graduated from college. Univariate analysis showed that being employed (odds ratio [OR] 0.24; 95% confidence interval [CI] 0.10-0.61), insured (OR 0.23; 95% CI 0.09-0.60), reporting higher instrumental, informational, and emotional support (OR 0.75; 95% CI 0.60-0.94; OR 0.62; 95% CI 0.49-0.78; and OR 0.48; 95% CI 0.35-0.65, respectively), visiting a primary care physician in the last year (OR 0.16; 95% CI 0.04-0.61) and reporting better physician-patient interactions (OR 0.56; 95% CI 0.37-0.87) were negatively associated with depression. Patient's perception of staff disrespect (OR 2.30; 95% CI 1.19-4.47) and worse skin-related quality of life (OR 1.04; 95% CI 1.02-1.06) rendered higher risk. In multivariate analysis, only perception of staff disrespect (OR 2.35; 95% CI 1.06-5.17) and lower emotional support (OR 0.48; 95% CI 0.35-0.66) remained associated with depression.

CONCLUSION

Over one-quarter of a predominantly Black population-based cohort of individuals with primary CCLE reported moderate to severe depression, a rate three to five times higher than described previously in the general population from the same metropolitan Atlanta area. Our findings suggest that, while patient's perception of discrimination in the healthcare setting may play a role as a determinant of depression, social support may be protective. In addition to routine mental health screening and depression treatment, interventions directed at providing emotional support and improving office staff interpersonal interactions may contribute to reduce the risk of depression in patients with CCLE.

Motion sickness and tilts of the inertial force environment: active suspension systems vs. active passengers

BACKGROUND

Maneuvering in vehicles exposes occupants to low frequency forces (< 1 Hz) which can provoke motion sickness.

HYPOTHESIS

Aligning with the tilting inertial resultant (gravity + imposed horizontal acceleration: gravito-inertial force (GIF)) may reduce motion sickness when tilting is either 'active' (self-initiated; Experiment 1) or 'passive' (suspension machinery; Experiment 2).

METHODS

Exp 1: Twelve seated subjects were exposed to continuous horizontal translational oscillation through the body x-axis (3.1 m x S(-2) peak acceleration, 0.20 Hz) while making head tilts which were either aligned or misaligned (180 degrees out of phase) with respect to GIF. The two sessions were one week apart at the same time of day, counterbalanced for order. Head tilts were controlled by tracking a moving LED display and head trajectory was verified by accelerometry. Motion continued until moderate nausea was achieved (motion endpoint) or until a 30 min cut-off. Exp 2: A different group of 12 subjects were exposed to continuous horizontal translational sinusoidal oscillation through the body x-axis (2.0 m x S(-2) peak acceleration, 0.176 Hz) while seated in a cab which was tilted by suspension machinery around the y-axis of the ears so that GIF was aligned or misaligned (180 degrees out of phase) with the body z-axis.

RESULTS

Exp 1: Mean +/- SD time to motion endpoint was significantly longer for aligned (19.2 +/- 12.0 min) than for misaligned (17.8 +/- 13.0 min; p < 0.05, two-tail). Exp 2: Mean +/- SD time to motion endpoint was significantly shorter for aligned (21.8 +/- 10.9 min) than for misaligned (28.3 +/- 5.8 min; p < 0.01, two-tail).

CONCLUSIONS

Whether or not compensatory tilting protects against (Exp 1) or contributes to (Exp 2) motion sickness may be influenced by whether the tilting is under the active control of the person (e.g., car driver) or under external control (e.g., passenger in a high-speed tilting train).

Collective Adaptation: The Exchange of Coding Segments

Coding segments are those subsegments of the chromosome that contribute positively to the fitness evaluation of the chromosome. Clique detection is a NP-complete problem in which we can detect such coding segments. We extract coding segments from chromosomes, and we investigate the duplication of coding segments inside the chromosome and the collection of coding segments outside of the chromosome. We find that duplication of coding segments inside the chromosomes provides a back-up mechanism for the search heuristics. We further find local search in a collective memory of coding segments outside of the chromosome, collective adaptation, enables the search heuristic to represent partial solutions that are larger than realistic chromosomes lengths and to express the solution outside of the chromosome.

Bilateral testicular torsion in a pre-term neonate

Bilateral testicular torsion in the neonate, although uncommon, is being reported with increasing frequency. Most previously reported cases have been full term, average to above average weight infants born with nonviable testes. We report a case of bilateral neonatal testicular torsion in a 32-week newborn in whom testicular viability may have been preserved by pre-term birth.
