RESUMEN

We used a reverse-correlation image-classification paradigm to visualize facial representations of immigrants and citizens in the United States. Visualizations of immigrants' faces were judged by independent raters as less trustworthy and less competent and were more likely to be categorized as a non-White race/ethnicity than were visualizations of citizens' faces. Additionally, image generators' personal characteristics (e.g., implicit and explicit evaluations of immigrants, nativity status) did not reliably track with independent judges' ratings of image generators' representations of immigrants. These findings suggest that anti-immigrant sentiment and racial/ethnic assumptions characterize facial representations of immigrants in the United States, even among people who harbor positivity toward immigrants.

RESUMEN

The anterolateral system (ALS) is a major ascending pathway from the spinal cord that projects to multiple brain areas and underlies the perception of pain, itch, and skin temperature. Despite its importance, our understanding of this system has been hampered by the considerable functional and molecular diversity of its constituent cells. Here, we use fluorescence-activated cell sorting to isolate ALS neurons belonging to the Phox2a-lineage for single-nucleus RNA sequencing. We reveal five distinct clusters of ALS neurons (ALS1-5) and document their laminar distribution in the spinal cord using in situ hybridization. We identify three clusters of neurons located predominantly in laminae I-III of the dorsal horn (ALS1-3) and two clusters with cell bodies located in deeper laminae (ALS4 and ALS5). Our findings reveal the transcriptional logic that underlies ALS neuronal diversity in the adult mouse and uncover the molecular identity of two previously identified classes of projection neurons. We also show that these molecular signatures can be used to target groups of ALS neurons using retrograde viral tracing. Overall, our findings provide a valuable resource for studying somatosensory biology and targeting subclasses of ALS neurons.

RESUMEN

Objective: To identify and support correction of misspelled medication names recorded as free text, we compared the relative effectiveness of two user-friendly methods, used without reliance on clinical knowledge. Methods: Leveraging the SAS® COMPGED function, fuzzy string search programs examined 1.8 million medication records from 183,600 World Trade Center General Responder Cohort monitoring visits conducted in New York and New Jersey between 7/16/2002 and 3/31/2021, producing replicable generalized edit distance scores between the reported and correct spelling. Scores < 120 were selected as optimal and compared to Stedman's 2020 Plus Medical/Pharmaceutical Spell Checker first suggested word, used as the comparative standard because it employs both spelling and phonetic similarities to suggest matching words. We coded each methods' results as identifying or not identifying the medications within each visit. Results: Most types of medications (94.4 % anxiety, 98.4 % asthma and 94.6 % ulcer/gastroesophageal reflux disease) were correctly spelled. Cross tabulations assessed the agreement (anxiety 99.9 %, asthma 99.6 % and 98.4 % ulcer/ gastroesophageal reflux disease), false positive (respectively 0.02 %, 0.03 % and 2.0 %) and false negative (respectively 1.9 %, 0.5 % and 1.0 %) values. Scores < 120 occasionally correctly identified medications missed by the spell checker. We observed no difference in medication misspellings across socio-economically and culturally diverse patient characteristics. Conclusions: Both methods efficiently identified most misspelled medications, greatly minimizing the review and rectification needed. The fuzzy method is more universally applicable for condition-specific medications identification, but requires more programming skills. The spell checker is inexpensive, but benefits from modest programming skills and is only available in some languages.

RESUMEN

Racial stereotypes are commonly activated by informational cues that are detectable in people's faces. Here, we used a sequential priming task to examine whether and how the salience of emotion (angry/scowling vs. happy/smiling expressions) or apparent race (Black vs. White) information in male face primes shapes racially biased weapon identification (gun vs. tool) decisions. In two experiments (Ntotal = 546) using two different manipulations of facial information salience, racial bias in weapon identification was weaker when the salience of emotion expression versus race was heightened. Using diffusion decision modeling, we tested competing accounts of the cognitive mechanism by which the salience of facial information moderates this behavioral effect. Consistent support emerged for an initial bias account, whereby the decision process began closer to the "gun" response upon seeing faces of Black versus White men, and this racially biased shift in the starting position was weaker when emotion versus race information was salient. We discuss these results vis-à-vis prior empirical and theoretical work on how facial information salience moderates racial bias in decision-making.

RESUMEN

BACKGROUND AND AIMS: Gastric varices (GV) are reported in up to 20% of patients with portal hypertension, and bleeding is often more severe and challenging than oesophageal variceal bleeding. There is limited data on prophylaxis of GV bleeding or management in the acute setting, and different techniques are utilised. This study aims to evaluate outcomes following endoscopic ultrasound (EUS) guided placement of coils in combination with thrombin to manage GV. METHODS: We retrospectively reviewed all patients treated with combination EUS-guided therapy with coils and thrombin between October 2015 and February 2020. RESULTS: 20 patients underwent 33 procedures for GV therapy; 16/20 (80%) were type 1 Isolated GV (IGV1), and the remainder were type 2 Gastroesophageal Varices (GOV2). Median follow-up was 842 days (Interquartile range (IQR) 483-961). 17/20 (85%) had underlying cirrhosis, the most common aetiologies being alcohol-related liver disease and non-alcoholic steatohepatitis (NASH). The median Child-Pugh (CP) score was 6 (IQR 5-7). In 11/20 (55%) cases, the indication was secondary prophylaxis to prevent rebleeding; in 2/20 (10%), the bleeding was acute. Technical success was achieved in 19/20 (95%) of cases. During follow-up, the obliteration of flow within the varices was achieved in 17/20 (85%) cases. The 6-week survival was 100%, and 2 adverse events were reported: cases of rebleeding at day 5 and day 37; both rebleeds were successfully managed endoscopically. CONCLUSIONS: EUS-guided GV obliteration combining coil placement with thrombin, in our experience, is technically safe with good medium-term efficacy. A multicenter randomised controlled trial comparing different treatment strategies would be desirable to understand options better.

RESUMEN

The commencement of a new editorial tenure within the Journal of Personality and Social Psychology: Attitudes and Social Cognition (JPSP: ASC) provides an opportunity for reflection regarding the journal's core mission. The editors recognize that social psychology is at a crossroads due to competing demands that may have led to reduced submissions and posed challenges for previous editors in filling the journal's pages. Now, JPSP: ASC has been allotted more pages to allow for growth during this editorial term. Although this is desirable for the field, it adds to the pressure of identifying articles for publication given the difficulties filling the pages during previous editorial terms. As the premier outlet of social psychology since 1965, JPSP: ASC will retain its centrality if we increase submissions and publish more articles, while continuing to strive to communicate methodologically trustworthy, intellectually stimulating, and socially relevant research, in a responsible fashion.

RESUMEN

OBJECTIVES: To determine if quantitative assessment of relative (R) and absolute (A) arterial phase hyperenhancement (APHE) and washout (WO) applied to indeterminate nodules on CT would improve the overall sensitivity of detection of hepatocellular carcinoma (HCC). METHODS: One-hundred and fourteen patients (90 male; mean age, 65 years) with 210 treatment-naïve HCC nodules (190 HCCs, 20 benign) who underwent 4-phase CT were included in this retrospective study. Four radiologists independently assigned a qualitative LR (LI-RADS) category per nodule. LR-3/4 nodules were then quantitatively analyzed by the 4 readers, placing ROIs within nodules and adjacent liver parenchyma. A/R-APHE and WO were calculated, and per-reader sensitivity and specificity updated. Interobserver agreement and AUCs were calculated per reader. RESULTS: Qualitative readers 1-4 categorized 57, 69, 57, and 63 nodules as LR-3/4 respectively with moderate to substantial agreement in LR category (kappa 0.56-0.69, p < 0.0001); their diagnostic performances in the detection of HCC were 80%, 73.2%, 77.4%, and 77.4% sensitivity, and 100%, 95%, 70%, and 100% specificity, respectively. A threshold of ≥ 20 HU for A-APHE increased overall sensitivity of HCC detection by 0.5-3.1% without changing specificity for the subset of nodules APHE - /WO + on qualitative read, with 2, 6, 6, and 1 additional HCC detected by readers 1-4. Relative and various A-WO formulae and thresholds all increased sensitivity, but with a drop in specificity for some/all readers. CONCLUSION: Quantitatively assessed A-APHE showed potential to increase sensitivity and maintain specificity of HCC diagnosis when selectively applied to indeterminate nodules demonstrating WO without subjective APHE. Quantitatively assessed R and A-WO increased sensitivity, however reduced specificity. CLINICAL RELEVANCE STATEMENT: A workflow using selective quantification of absolute arterial enhancement is routinely employed in the CT assessment of renal and adrenal nodules. Quantitatively assessed absolute arterial enhancement is a simple tool which may be used as an adjunct to help increase sensitivity and maintain specificity of HCC diagnosis in indeterminate nodules demonstrating WO without subjective APHE. KEY POINTS: • In indeterminate nodules categorized as LI-RADS 3/4 due to absent subjective arterial phase hyperenhancement, a cut-off for absolute arterial phase hyperenhancement of ≥ 20 HU may increase the overall sensitivity of detection of HCC by 0.5-3.1% without affecting specificity. • Relative and various absolute washout formulae and cut-offs increased sensitivity of HCC detection, but with a drop in specificity for some/all readers.

RESUMEN

The superficial dorsal horn (SDH) of the spinal cord contains a diverse array of neurons. The vast majority of these are interneurons, most of which are glutamatergic. These can be assigned to several populations, one of which is defined by expression of gastrin-releasing peptide receptor (GRPR). The GRPR cells are thought to be "tertiary pruritoceptors," conveying itch information to lamina I projection neurons of the anterolateral system (ALS). Surprisingly, we recently found that GRPR-expressing neurons belong to a morphological class known as vertical cells, which are believed to transmit nociceptive information to lamina I ALS cells. Little is currently known about synaptic circuits engaged by the GRPR cells. Here we combine viral-mediated expression of PSD95-tagRFP fusion protein with super-resolution microscopy to reveal sources of excitatory input to GRPR cells. We find that they receive a relatively sparse input from peptidergic and non-peptidergic nociceptors in SDH, and a limited input from A- and C-low threshold mechanoreceptors on their ventral dendrites. They receive synapses from several excitatory interneuron populations, including those defined by expression of substance P, neuropeptide FF, cholecystokinin, neurokinin B, and neurotensin. We investigated downstream targets of GRPR cells by chemogenetically exciting them and identifying Fos-positive (activated) cells. In addition to lamina I projection neurons, many ALS cells in lateral lamina V and the lateral spinal nucleus were Fos-positive, suggesting that GRPR-expressing cells target a broader population of projection neurons than was previously recognised. Our findings indicate that GRPR cells receive a diverse synaptic input from various types of primary afferent and excitatory interneuron, and that they can activate ALS cells in both superficial and deep regions of the dorsal horn.

RESUMEN

PURPOSE: While severely distressing events are known to affect mental health adversely, some survivors develop only short-lived or no psychiatric symptoms in the aftermath of a disaster. In the WTC Health Program General Responder Cohort (WTCHP GRC) we examined whether social support was protective against the development of depression or anxiety symptoms after the 9/11 WTC attacks and explored in a subsample whether trait resilience moderated this relationship. METHODS: We analyzed data from 14,033 traditional and 13,478 non-traditional responders who attended at least three periodic health monitoring visits between 2002 and 2019. Linear mixed-effects models were used to examine depression (Patient Health Questionnaire-9; PHQ-9) and anxiety (Generalized Anxiety Disorder screener; GAD-7) scores. In a subsample of 812 participants, we also assessed if the association between social support and symptoms was moderated by an individual's trait resilience level (Connor-Davidson Resilience Scale, CD-RISC). RESULTS: For both traditional and non-traditional responders, perceived social support around 9/11 was associated with lower levels of depressive (ß = - 0.24, S.E. = 0.017, z = - 14.29, p < 0.001) and anxiety symptoms (ß = - 0.17, S. E. = 0.016, z = - 10.48, p < 0.001). Trait resilience scores were higher in responders with at least one source of social support during the aftermath of 9/11 compared to those without (mean 71.56, SD 21.58 vs mean 76.64, SD 17.06; ß = 5.08, S.E. = 0.36, p < 0.001). Trait resilience moderated the association between social support and depressive (p < 0.001) and anxiety trajectories (p < 0.001) for traditional responders. CONCLUSION: Our findings suggest that perceived social support around a severely distressing event may have long-term protective effects on symptoms of depression and anxiety.

RESUMEN

Neuropeptide Y targets the Y1 receptor (Y1) in the spinal dorsal horn (DH) to produce endogenous and exogenous analgesia. DH interneurons that express Y1 (Y1-INs; encoded by Npy1r) are necessary and sufficient for neuropathic hypersensitivity after peripheral nerve injury. However, as Y1-INs are heterogenous in composition in terms of morphology, neurophysiological characteristics, and gene expression, we hypothesized that a more precisely defined subpopulation mediates neuropathic hypersensitivity. Using fluorescence in situ hybridization, we found that Y1-INs segregate into 3 largely nonoverlapping subpopulations defined by the coexpression of Npy1r with gastrin-releasing peptide (Grp/Npy1r), neuropeptide FF (Npff/Npy1r), and cholecystokinin (Cck/Npy1r) in the superficial DH of mice, nonhuman primates, and humans. Next, we analyzed the functional significance of Grp/Npy1r, Npff/Npy1r, and Cck/Npy1r INs to neuropathic pain using a mouse model of peripheral nerve injury. We found that chemogenetic inhibition of Npff/Npy1r-INs did not change the behavioral signs of neuropathic pain. Further, inhibition of Y1-INs with an intrathecal Y1 agonist, [Leu31, Pro34]-NPY, reduced neuropathic hypersensitivity in mice with conditional deletion of Npy1r from CCK-INs and NPFF-INs but not from GRP-INs. We conclude that Grp/Npy1r-INs are conserved in higher order mammalian species and represent a promising and precise pharmacotherapeutic target for the treatment of neuropathic pain.

RESUMEN

INTRODUCTION: It is unclear whether differences in health outcomes by racial and ethnic groups among World Trade Center (WTC) rescue and recovery workers reflect those of the population of New York State (NYS) or show distinct patterns. We assessed cancer incidence in WTC workers by self-reported race and ethnicity, and compared it to population figures for NYS. METHODS: A total of 61,031 WTC workers enrolled between September 11, 2001 and January 10, 2012 were followed to December 31, 2015. To evaluate the association between race/ethnicity and cancer risk, Poisson regression analysis was used to estimate hazard ratios (HR) adjusted for WTC exposure, age, calendar year, sex and, for lung cancer, cigarette smoking. RESULTS: In comparison to Whites, Black workers had a higher incidence of prostate cancer (HR = 1.99, 95% CI = 1.69-2.34) and multiple myeloma (HR = 3.57, 95% CI = 1.97-6.45), and a lower incidence of thyroid (HR = 0.41, 95% CI = 0.22-0.78) and colorectal cancer (HR = 0.57; 95% CI = 0.33-0.98). Hispanic workers had a higher incidence of liver cancer (HR = 4.03, 95% CI = 2.23-7.28). Compared with NYS population, White workers had significantly higher incidence of prostate cancer (HR = 1.26, 95% CI = 1.18-1.35) and thyroid cancer (HR = 1.80, 95% CI = 1.55-2.08), while Black workers had significantly higher incidence of prostate cancer (HR = 1.22, 95% CI = 1.05-1.40). CONCLUSION: Cancer incidence in WTC workers generally reflects data from the NYS population, but some differences were identified that merit further investigation.

RESUMEN

BACKGROUND AND AIMS: Bleeding from parastomal varices causes significant morbidity and mortality. Treatment options are limited, particularly in high-risk patients with significant underlying liver disease and other comorbidities. The use of EUS-guided embolisation coils combined with thrombin injection in gastric varices has been shown to be safe and effective. Our institution has applied the same technique to the treatment of parastomal varices. METHODS: A retrospective review was performed of 37 procedures on 24 patients to assess efficacy and safety of EUS-guided injection of thrombin, with or without embolisation coils for treatment of bleeding parastomal varices. All patients had been discussed in a multidisciplinary team meeting, and correction of portal hypertension was deemed to be contraindicated. Rebleeding was defined as stomal bleeding that required hospital admission or transfusion. RESULTS: All patients had significant parastomal bleeding at the time of referral. 100% technical success rate was achieved. 70.8% of patients had no further significant bleeding in the follow-up period (median 26.2 months) following one procedure. 1-year rebleed-free survival was 80.8% following first procedure. 7 patients (29.1%) had repeat procedures. There was no significant difference in rebleed-free survival following repeat procedures. Higher age was associated with higher risk of rebleeding. No major procedure-related complications were identified. CONCLUSIONS: EUS-guided thrombin injection, with or without embolisation coils, is a safe and effective technique for the treatment of bleeding parastomal varices, particularly for patients for whom correction of portal venous hypertension is contraindicated.

RESUMEN

Unmyelinated non-peptidergic nociceptors (NP afferents) arborise in lamina II of the spinal cord and receive GABAergic axoaxonic synapses, which mediate presynaptic inhibition. However, until now the source of this axoaxonic synaptic input was not known. Here we provide evidence that it originates from a population of inhibitory calretinin-expressing interneurons (iCRs), which correspond to lamina II islet cells. The NP afferents can be assigned to 3 functionally distinct classes (NP1-3). NP1 afferents have been implicated in pathological pain states, while NP2 and NP3 afferents also function as pruritoceptors. Our findings suggest that all 3 of these afferent types innervate iCRs and receive axoaxonic synapses from them, providing feedback inhibition of NP input. The iCRs also form axodendritic synapses, and their targets include cells that are themselves innervated by the NP afferents, thus allowing for feedforward inhibition. The iCRs are therefore ideally placed to control the input from non-peptidergic nociceptors and pruritoceptors to other dorsal horn neurons, and thus represent a potential therapeutic target for the treatment of chronic pain and itch.

RESUMEN

Somatosensory information is processed by a complex network of interneurons in the spinal dorsal horn. It has been reported that inhibitory interneurons that express neuropeptide Y (NPY), either permanently or during development, suppress mechanical itch, with no effect on pain. Here, we investigate the role of interneurons that continue to express NPY (NPY-INs) in the adult mouse spinal cord. We find that chemogenetic activation of NPY-INs reduces behaviours associated with acute pain and pruritogen-evoked itch, whereas silencing them causes exaggerated itch responses that depend on cells expressing the gastrin-releasing peptide receptor. As predicted by our previous studies, silencing of another population of inhibitory interneurons (those expressing dynorphin) also increases itch, but to a lesser extent. Importantly, NPY-IN activation also reduces behavioural signs of inflammatory and neuropathic pain. These results demonstrate that NPY-INs gate pain and itch transmission at the spinal level, and therefore represent a potential treatment target for pathological pain and itch.

RESUMEN

The concept of race or ethnic concordance between health care provider and patient has emerged as a dimension of the patient-physician relationship that could influence health outcomes for patients from minoritized groups, particularly through differences in the way physicians communicate with patients based on race or ethnicity. However, two decades of study on concordance and physician-patient communication have produced contradictory results. Given the heightened societal awareness of racism and the persistence of health disparities, there is a need for a comprehensive review of the current state of knowledge. This review sets out to determine how communication patterns differ in race/ethnicity concordant versus discordant patient-physician medical encounters. Thirty-three studies employing a range of methodologies were identified. In most analyses, after accounting for covariates, no relationship was found between race/ethnicity concordance and communication variables. Race/ethnicity concordance with their physician does not appear to influence the quality of communication for most patients from minoritized groups. A number of methodological weaknesses were identified in existing research, among them: few studies investigated potential explanatory variables, the heterogeneity of ethnic and cultural experience was over-simplified, there was little consistency in operationalization of communication variables, and the physician-patient dynamic was inadequately conceptualized.

RESUMEN

Excitatory interneurons in the superficial dorsal horn (SDH) are heterogeneous, and include a class known as vertical cells, which convey information to lamina I projection neurons. We recently used pro-NPFF antibody to reveal a discrete population of excitatory interneurons that express neuropeptide FF (NPFF). Here, we generated a new mouse line (NPFFCre) in which Cre is knocked into the Npff locus, and used Cre-dependent viruses and reporter mice to characterise NPFF cell properties. Both viral and reporter strategies labelled many cells in the SDH, and captured most pro-NPFF-immunoreactive neurons (75-80%). However, the majority of labelled cells lacked pro-NPFF, and we found considerable overlap with a population of neurons that express the gastrin-releasing peptide receptor (GRPR). Morphological reconstruction revealed that most pro-NPFF-containing neurons were vertical cells, but these differed from GRPR neurons (which are also vertical cells) in having a far higher dendritic spine density. Electrophysiological recording showed that NPFF cells also differed from GRPR cells in having a higher frequency of miniature EPSCs, being more electrically excitable and responding to a NPY Y1 receptor agonist. Together, these findings indicate that there are at least two distinct classes of vertical cells, which may have differing roles in somatosensory processing.

RESUMEN

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is associated with a range of adverse outcomes in adult life. However it is unclear whether the risk pathways to adverse adult outcomes are established during childhood or whether associations are driven by concurrent ADHD symptoms that have persisted to adulthood. Methods: We examined associations between broadly defined child-limited (remitted) and persistent ADHD (assessed using the ADHD subscale of the Strengths and Difficulties Questionnaire) with social outcomes (low emotional and instrumental support, antisocial behaviour, employment, receipt of state benefits as an indicator of socio-economic disadvantage, homelessness) at age 25 years in a UK longitudinal population sample ALPSAC (the Avon Longitudinal Study of Parents and Children, age 25 data collected between years 2017 and 2018): total N=6439. Results: Up to 20% of young-people with less favourable social outcomes at age 25 had persistent ADHD. Persistent ADHD was associated with an increased likelihood of being not in education, employment or training (NEET: OR=3.71, 95% CI=2.06 to 6.67, p=1x10-05) and receiving state benefits (OR=2.72, 95% CI=1.62 to 4.57, p=2x10-04) at age 25 years compared to those without ADHD. We did not find strong evidence of associations between child-limited ADHD and social outcomes (NEET OR=1.20, 95% CI=0.54 to 2.69, p=0.65; state benefits OR=1.38, 95% CI=0.76 to 2.51, p=0.29). Persistent ADHD associations with negative social outcomes were observed across family-of-origin income groups, sex and were not explained by comorbidity. Conclusion: Our findings highlight the importance of continued monitoring and management of ADHD symptoms and related social as well as clinical outcomes across development into adulthood. Future research is needed to identify what factors promote positive social outcomes, including effective treatment of adult ADHD symptoms.
