Physiological Responses to Organizational Stressors Among Police Managers.

Police officers demonstrate increased risk of physical and mental health conditions due to repeated and prolonged exposure to stressful occupational conditions. Occupational stress is broken into two types: operational stress, related to the content of field duties (e.g., physical demands); and organizational stress, related to cultural and structural contexts (e.g., interpersonal relationships). Applied police research focuses on physiological activation in operational tasks as a mechanism explaining health risk and non-optimal performance outcomes. However, recent survey-based studies indicate numerous organizational stressors associated with self-reported mental health symptoms. The question of whether organizational stressors elicit significant physiological activity remains unknown. The current proof-of-concept field study tests the hypothesis that police managers will display significant physiological reactivity before, during, and after engaging in reality-based scenarios representative of stressful police management tasks developed from evidence-based pedagogical approaches. A sample of 25 training police managers (7 female, M = 16 +/- 5.3 years of experience) completed 5 reality-based scenarios, including resolving a heated conflict between colleagues, delivering negative feedback to a subordinate, and critical incident command. Significant increases in heart rate relative to rest were observed during all tasks, and in anticipation of several tasks. Greater increases in reactive heart rate were associated with longer recovery times. Sex differences and relationships between objective biological and subjective psychological measures of stress are discussed. The current findings demonstrate significant physiological responses to organizational stressors similar to levels observed during operational tasks, despite the absence of physical or aerobic exertion. Implications for police health and training are discussed.

Acute toxicity and bioaccumulation of common urban metals in Bombus impatiens life stages.

Metal contamination is ubiquitous in urban areas and represents a risk to arthropod species. Bees are exposed to metals while foraging within contaminated landscapes from multiple sources. Eliminating the risk of bee exposure to metals is complex, and requires an understanding of how bees become contaminated, how metals accumulate within bee bodies, and how this exposure influences their health. We selected Bombus impatiens, the common eastern bumble bee, as our focal species because it is the most frequently encountered bumble bee species in the eastern United States and common within urban greenspaces. The aims of this study were to quantify the lethal concentration exposure limit (LC50) for B. impatiens foragers, assess the bioaccumulation ability of environmentally relevant concentrations of common urban metals in adults, larvae, and pupae, and compare the LC50 values against field relevant concentrations collected by foraging bumble bees within a legacy city. Bumble bees were orally exposed to arsenic oxide, cadmium chloride, or chromium oxide in sucrose solution to encourage consumption. The LC50 for arsenic (As2O3 36.4 mg/L), cadmium (CdCl2 10.3 mg/L), and chromium (CrO3 189.6 mg/L) are 202×, 79×, and 1459× greater than concentrations found within urban bumble bee collected provisions, respectively. Adult bumble bees fed field realistic concentrations of metals accumulate significant amounts of cadmium and lead within their bodies, but do not accumulate chromium and arsenic. Additionally, adults accumulate significantly higher concentrations of metals than brood. While bumble bee foragers are unlikely to encounter lethal metal concentrations while foraging in contaminated landscapes, it is crucial to consider and understand how sublethal concentrations impact overall colony functioning. The results from this study highlight the need to identify hazards and bioaccumulation ability of common metals as bees respond differently to each metal species, as well as the impacts of metal mixtures on bioaccumulation and toxicity.

Economic Abuse and Help-Seeking Intentions Among Adolescents.

Economic adolescent relationship abuse (ARA) includes coercive behaviors leading to interference with education, employment, and finances. To date, no study has examined help seeking among adolescents and young adults if they were to experience economic ARA. The goals of this article include examining: (a) help-seeking intentions of adolescents regarding economic ARA; (b) help-seeking sources and reasons for not seeking help; and (c) differences in help-seeking intentions based on age, race/ethnicity, gender identity, and experiences of economic ARA. We conducted a cross-sectional survey of adolescents ages 13-19 focused on economic ARA experiences and help seeking. We performed descriptive statistics of help-seeking intentions, sources, and barriers. We utilized logistic regression, adjusted for age, race/ethnicity, and gender identity, to explore associations between economic ARA victimization and help-seeking intentions. Of 2,852 participants, 56% said they would seek help for economic ARA. Adolescents with positive help-seeking intentions shared that they would seek help from their parents (43%) or friends (35%). Those less likely to seek help were concerned about others finding out (32%), not being believed (31%), or authority figures being notified (31%). Help-seeking intentions were lower among Black/African American adolescents (aOR = 0.55, CI [0.43, 0.70]) and Multiracial adolescents (aOR = 0.26, CI [0.16, 0.42]) compared to White adolescents. Help-seeking intentions were higher among gender diverse adolescents (aOR = 5.78, CI [2.98, 11.22]) and those ages 15-17 years (aOR = 1.84, CI [1.36, 2.47]) compared to those identifying as female and ages 18-19 years. Help-seeking intentions were lower among adolescents who experienced economic ARA (aOR = 0.61, CI [0.51, 0.72]). While the majority of adolescents reported that they would seek help if they experienced economic ARA, those who had experienced economic ARA were less likely to report intentions to seek help. Supportive interventions for adolescents experiencing economic ARA are needed.

Perinatal Economic Abuse: Experiences, Impacts, and Needed Resources.

Introduction: Economic abuse is one form of intimate partner violence (IPV) intended to control a survivor's ability to make, save, or spend money to gain power over them. Perinatal people may be more vulnerable to economic abuse due to changes in employment and finances. This study's aims were to explore how economic abuse manifests among pregnant and parenting survivors and how best to support pregnant and parenting survivors of economic abuse. Methods: We conducted virtual semistructured interviews with IPV survivors and IPV advocates. Participants were recruited through an online recruitment registry, national IPV organizations, and local domestic violence agencies. Interview audiorecordings were transcribed. We used a deductive-inductive thematic analysis approach. Two research team members individually coded each transcript and met to resolve discrepancies in coding. Results: We completed interviews with 18 advocates and 20 survivors. Participants described experiences of financial control, exploitation, and employment sabotage. Partners leveraged the criminal-legal, child welfare, and health care systems and cultural norms about pregnancy, including those related to gender and religion to financially harm survivors. Advocates described how economic abuse impacts marginalized survivors. Dream resources described include cash assistance, healthy relationship and financial education, and employer policies. Discussion: Survivors and advocates reported a variety of experiences with economic abuse during the perinatal period. Future interventions should focus on providing unrestricted cash transfers to survivors, developing education on economic abuse, and creating supportive policies in health care and employment settings. This study highlights the ways that economic abuse specifically impacts perinatal survivors and their children.

Esophageal body adaptation to Nissen fundoplication: Increased esophagogastric outflow resistance yields delayed and sustained peristaltic contractions without increased amplitude.

BACKGROUND: Improvement in lower esophageal sphincter (LES) competency after laparoscopic Nissen fundoplication (LNF) is well established, yet esophageal body physiology data are limited. We aimed to describe the impact of LNF on whole esophagus physiology using standard and novel manometric characteristics. METHODS: A cohort of patients with an intact fundoplication without herniation and no postoperative dysphagia were selected and underwent esophageal manometry at one-year after surgery. Pre- and post-operative manometry files were reanalyzed using standard and novel manometric characteristics and compared. KEY RESULTS: A total of 95 patients were included in this study. At 16.1 (8.7) months LNF increased LES overall and abdominal length and resting pressure (p < 0.0001). Outflow resistance (IRP) increased [5.8 (3-11) to 11.1 (9-15), p < 0.0001] with a 95th percentile of 20 mmHg in this cohort of dysphagia-free patients. Distal contractile integral (DCI) also increased [1177.0 (667-2139) to 1321.1 (783-2895), p = 0.002], yet contractile amplitude was unchanged (p = 0.158). There were direct correlations between pre- and post-operative DCI [R: 0.727 (0.62-0.81), p < 0.0001] and postoperative DCI and postoperative IRP [R: 0.347 (0.16-0.51), p = 0.0006]. Contractile front velocity [3.5 (3-4) to 3.2 (3-4), p = 0.0013] was slower, while distal latency [6.7 (6-8) to 7.4 (7-9), p < 0.0001], the interval from swallow onset to proximal smooth muscle initiation [4.0 (4-5) to 4.4 (4-5), p = 0.0002], and the interval from swallow onset to point when the peristaltic wave meets the LES [9.4 (8-10) to 10.3 (9-12), p < 0.0001] were longer. Esophageal length [21.9 (19-24) to 23.2 (21-25), p < 0.0001] and transition zone (TZ) length [2.2 (1-3) to 2.5 (1-4), p = 0.004] were longer. Bolus clearance was inversely correlated with TZ length (p = 0.0002) and time from swallow onset to proximal smooth muscle initiation (p < 0.0001). Bolus clearance and UES characteristics were unchanged (p > 0.05). CONCLUSIONS & INFERENCES: Increased outflow resistance after LNF required an increased DCI. However, this increased contractile vigor was achieved through sustained, not stronger, peristaltic contractions. Increased esophageal length was associated with increased TZ and delayed initiation of smooth muscle contractions.

Cyanosis in a Newborn Immediately after Birth.

Cyanosis in a Newborn Immediately after BirthA male neonate, weighing 3.9 kg, was delivered via Cesarean section at 39 weeks of gestation. He cried immediately after birth, but his whole body appeared blue and he had low muscle tone that did not improve with suctioning and stimulation. Blow-by with 100% oxygen was initiated, and pulse oximetry on his left hand measured 40%. What is the diagnosis?
