Evidence for validity of the epidemic-pandemic impacts inventory (brief healthcare module): Internal structure and association with other variables.

The COVID-19 pandemic has subjected healthcare workers to enormous stress. Measuring the impact of this public health emergency is essential to developing strategies that can effectively promote resilience and wellness. The Epidemic-Pandemic Impacts Inventory Supplemental Healthcare Module-Brief Version (EPII-SHMb) was developed to measure impacts among occupational cohorts serving on the front lines of healthcare. While this instrument has been utilized in COVID-19 related studies, little is known about its psychometric properties. This study collects evidence for validity of the EPII-SHMb by evaluating its internal structure and how its scores associate with other variables. Physicians and nursing staff across a large New York health system were cross-sectionally surveyed using an online questionnaire between June and November 2020. Exploratory factor analysis resulted in a 3-factor solution, identifying factors Lack of Workplace Safety (7 items), Death/Dying of Patients (3 items), and Lack of Outside Support (2 items). Internal consistency was high overall and within physician/nursing and gender subgroups (Cronbach's alpha: 0.70 - 0.81). Median scores on Death/Dying of Patients were higher among those who directly cared for COVID-19 patients or worked in COVID-19 hospital units. These results are promising. Additional studies evaluating other dimensions of validity are necessary.

Physician challenges and supports during the first wave of the COVID-19 pandemic: A mixed methods study.

Introduction: During the COVID-19 pandemic, physicians encountered significant COVID-19-related negative experiences and psychological distress in both their personal and professional lives. To understand the factors that negatively impact physician well-being, a number of studies have pointed to multiple work system factors such as excessive workload and workflow interruptions. In addition, studies have shown that positive interpersonal relationships that provide social support may also serve as a buffering role against psychological distress. The aim of our study explores the challenges and sources of support for physicians relative to mental health symptoms. Methods: In this study, We used a cross-sectional study design with a convergent parallel mixed method approach combining both qualitative and quantitative data collected in parallel from a self-report questionnaire immediately following the first wave of COVID-19. The aim of our study explores the challenges and sources of support for physicians relative to mental health symptoms. Results: Of the 457 physicians in the study, the most frequently potential negative occupational experiences were, "Being at risk of contracting COVID-19 from patients/co-workers" (90.5%) and "Contact with distressed family members who cannot be with a loved one" (69.5%). We identified five common themes for main sources of social support (e.g. emotional support from family/friends) and six themes for challenges (e.g., work-related demands exacerbated by the pandemic). Discussion: Our study highlights COVID-19 and other pandemic-related challenges that negatively impacted the mental health of physicians. Interventions that provide targeted organizational supports (e.g. sufficient PPE and child support), as well as specific sources of support (e.g. family and emotional), can attenuate those challenges and stressors experienced during a pandemic.

The Impact of Physicians' COVID-19 Pandemic Occupational Experiences on Mental Health.

OBJECTIVE: To examine the association between a number of negative COVID-19 occupational experiences and probable anxiety, depression, and PTSD among physicians. METHODS: Cross-sectional examination of longitudinal registry data consisting of physician personal and occupational well-being. Multivariable logistic regressions were performed to determine the association between negative COVID-19 experiences and outcomes. RESULTS: Of the 620 eligible physicians, approximately half were female (49%), and 71% white with a mean age of 46.51 (SD = 13.28). A one-point increase in negative experience score was associated with a 23% increase in probable anxiety (OR = 1.23, 95% CI: 1.14-1.34), a 23% increase in probable depression (OR = 1.23, 95% CI: 1.13-1.33), and a 41% increase in probable PTSD (OR = 1.41, 95% CI: 1.30-1.52). CONCLUSIONS: Negative pandemic experiences were strongly associated with adverse mental health outcomes while greater resilience was protective.

Prevalence of molecular subtypes of invasive breast cancer: A retrospective study.

BACKGROUND: Classification of breast cancers into different molecular subtypes using immunohistochemistry as a surrogate tool to DNA microarray technology has been identified. Aim of this study was to find the precise prevalence of molecular subtypes of invasive breast carcinoma using immunohistochemistry and to correlate it with histological and clinical prognostic factors. METHODS: A descriptive study design wherein 56 breast carcinoma cases diagnosed between May 2012 and Apr 2014 were reviewed and molecular subtyped using relevant immunohistochemical markers. Age, histological type, tumor size, tumor grade, lymphovascular emboli (LVE), nodal status and basal marker expressions were analyzed for all cases. Correlations between molecular subtypes and clinico-pathological characteristics were evaluated statistically. RESULTS: In our study group, average age of patients was 50.5 years and most of patients were diagnosed in stage II (54%). Luminal A subtype was most prevalent 34%, followed by Basal like/Triple negative subtype 25%. Luminal B and Her2/neu subtypes had same prevalence i.e. 18% each and Breast Tissue like/Unclassified subtype/Penta Negative subtype was 5%. All cases demonstrated positivity for the luminal cytokeratins 8/18. Histological grade and ER negative status showed strong correlations with basal markers. CONCLUSION: On the basis of hormone receptor, Her2 neu, EGFR and CK 5/6 expressions, breast carcinoma cases were classified into five distinct molecular subtypes which show significant differences in regards to morphological features, prognostic markers and there by predicting possible clinical outcome.

Altered activation in fronto-striatal circuits during sequential processing of conflict in unmedicated adults with obsessive-compulsive disorder.

BACKGROUND: The aim of this study was to examine the functioning of fronto-striatal brain circuits that support self-regulatory capacities including conflict resolution and sequential processing in unmedicated adults with obsessive-compulsive disorder (OCD). METHODS: We compared functional magnetic resonance imaging blood oxygen level-dependent response in 22 adults with OCD with 22 healthy, age-matched control subjects during performance of a Simon Spatial Incompatibility task. We used general linear modeling to compare groups in their patterns of brain activation during correct responses to conflict-laden stimuli and explore the effects of trial sequence on group differences. RESULTS: Behavioral performance on the Simon task did not differ between groups. In response to conflict-laden stimuli, OCD participants activated fronto-striatal regions significantly more than control subjects, specifically a right hemisphere cluster encompassing the putamen, insula, and inferior frontal gyrus. Their activation of this cluster was driven not by conflict on a current trial but by their response to the alternation of stimulus congruence (incongruent or congruent) across trial sequences (i.e., current and preceding trials) and was most accentuated in participants with more severe symptoms in the doubt/checking dimension. Functional connectivity from the putamen to other fronto-striatal regions was also greater in the OCD compared with control participants. CONCLUSIONS: When engaging the self-regulatory control necessary to resolve conflict and process alternating stimuli, OCD participants displayed excessive activation in a fronto-striatal circuit that differs from the orbitofrontal cortex-anterior cingulate cortex-caudate circuit typically implicated in OCD. Dysfunction in this circuit was associated with processing changes in the stimulus context. We speculate that this dysfunction might be related to the cognitive inflexibility typical of persons with OCD.
