RESUMO

Assessing environmental changes in Southern Ocean ecosystems is difficult due to its remoteness and data sparsity. Monitoring marine predators that respond rapidly to environmental variation may enable us to track anthropogenic effects on ecosystems. Yet, many long-term datasets of marine predators are incomplete because they are spatially constrained and/or track ecosystems already modified by industrial fishing and whaling in the latter half of the 20th century. Here, we assess the contemporary offshore distribution of a wide-ranging marine predator, the southern right whale (SRW, Eubalaena australis), that forages on copepods and krill from ~30°S to the Antarctic ice edge (>60°S). We analyzed carbon and nitrogen isotope values of 1,002 skin samples from six genetically distinct SRW populations using a customized assignment approach that accounts for temporal and spatial variation in the Southern Ocean phytoplankton isoscape. Over the past three decades, SRWs increased their use of mid-latitude foraging grounds in the south Atlantic and southwest (SW) Indian oceans in the late austral summer and autumn and slightly increased their use of high-latitude (>60°S) foraging grounds in the SW Pacific, coincident with observed changes in prey distribution and abundance on a circumpolar scale. Comparing foraging assignments with whaling records since the 18th century showed remarkable stability in use of mid-latitude foraging areas. We attribute this consistency across four centuries to the physical stability of ocean fronts and resulting productivity in mid-latitude ecosystems of the Southern Ocean compared with polar regions that may be more influenced by recent climate change.

RESUMO

BACKGROUND: Substance use disorders (SUDs) are prevalent in the USA yet remain dramatically undertreated. To address this care gap, the Accreditation Council for Graduate Medical Education (ACGME) approved revisions to the Program Requirements for Graduate Medical Education (GME) in Internal Medicine, effective July 1, 2022, requiring addiction medicine training for all internal medicine (IM) residents. The Veterans Health Administration (VHA) is a clinical training site for many academic institutions that sponsor IM residencies. This focus group project evaluated VHA IM residency site directors' perspectives about providing addiction medical education within VHA IM training sites. OBJECTIVE: To better understand the current state, barriers to, and facilitators of IM resident addiction medicine training at VHA sites. DESIGN: This was a qualitative evaluation based on semi-structured video-based focus groups. PARTICIPANTS: Participants were VHA IM site directors based at a VHA hospital or clinic throughout the USA. APPROACH: Focus groups were conducted using a semi-structured group interview guide. Two investigators coded each focus group independently, then met to create a final adjudicated coding scheme. Thematic analysis was used to identify key themes. KEY RESULTS: Forty-three participants from 38 VHA sites participated in four focus groups (average size: 11 participants). Six themes were identified within four pre-defined categories. Current state of training: most VHA sites offered no formal training in addiction medicine for IM residents. Barriers: addiction experts are often located outside of IM settings, and ACGME requirements were non-specific. Facilitators: clinical champions help support addiction training. Desired next steps: participants desired incentives to train or hire local champions and a pre-packaged didactic curriculum. CONCLUSIONS: Developing competent clinical champions and leveraging VHA addiction specialists from non-IM settings would create more addiction training opportunities for IM trainees at VHA sites. These insights can likely be applied to IM training at non-VHA sites.

RESUMO

Repeated anesthesia poses risks to patients but is often utilized to immobilize young children undergoing cranial radiation therapy for brain tumors. To enable young patients to remain still during cranial radiation therapy and thereby avoid sedation, medical and psychosocial clinicians can use behavioral and other supportive interventions. This case series illustrates the utility of behavioral training for motion control in 3 children 6 years old or younger who were treated for brain tumors. We demonstrate the efficacy of flexible, individualized intervention approaches to accommodate patients with brain tumors in the context of emotional dysregulation, significant communication barriers, and profound sensory deficits.

RESUMO

BACKGROUND: The average length of buprenorphine treatment for opioid use disorder is less than 6 months. OBJECTIVE: We conducted a systematic review to determine what factors were associated with longer retention in buprenorphine treatment. DESIGN: We searched Medline, Embase, and Cochrane Database of Systematic Reviews in February 2018. Articles were restricted to randomized controlled trials on human subjects, written in English, which contained ≥ 24 weeks of objective data on retention in buprenorphine treatment. MAIN MEASURES: We assessed whether dose of buprenorphine, treatment setting, or co-administration of behavioral therapy was associated with retention rates. KEY RESULTS: Over 14,000 articles were identified. Thirteen articles (describing 9 studies) met inclusion criteria. Measures of retention varied widely. Three studies compared doses of buprenorphine between 1 and 8 mg and showed significantly higher rates of retention with higher doses (p values < 0.01). All other studies utilized buprenorphine doses between 8 and 24 mg daily, without comparison. No study found a significant difference in retention between buprenorphine alone and buprenorphine plus behavioral therapy (p values > 0.05). Initiating buprenorphine while hospitalized or within criminal justice settings prior to outpatient treatment programs was significantly associated with retention in buprenorphine treatment (p values < 0.01 respectively). CONCLUSIONS: Setting of treatment initiation and a higher buprenorphine dose are associated with improved long-term treatment retention. More objective data on buprenorphine treatment programs are needed, including a standardized approach to defining retention in buprenorphine treatment programs. REGISTRATION: This review was registered with PROSPERO (#CRD42019120336) in March 2019.

RESUMO

BACKGROUND: Geographic cohorting is a hospital admission structure in which every patient on a given physician team is admitted to a dedicated hospital unit. Little is known about the long-term impact of this admission structure on patient outcomes and resident satisfaction. OBJECTIVE: To evaluate the effect of geographic cohorting on patient outcomes and resident satisfaction among inpatient internal medicine teaching services within an academic hospital. DESIGN AND INTERVENTION: We conducted an interrupted time series analysis examining patient outcomes before and after the transition to geographic cohorting of our 3 inpatient teaching services within a 520-bed academic hospital in November 2017. The study observation period spanned from January 2017 to October 2018, allowing for a 2-month run-in period (November-December 2017). PARTICIPANTS: We included patients discharged from the inpatient teaching teams during the study period. We excluded patients admitted to the ICU and observation admissions. MAIN MEASURES: Primary outcome was 6-month mortality adjusted for patient age, sex, race, insurance status, and Charlson Comorbidity Index (CCI) analyzed using a linear mixed effects model. Secondary outcomes included hospital length of stay (LOS), 7-day and 30-day readmission rate, Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores, and resident evaluations of the rotation. KEY RESULTS: During the observation period, 1720 patients (mean age 64, 53% female, 56% white, 62% Medicare-insured, mean CCI 1.57) were eligible for inclusion in the final adjusted model. We did not detect a significant change in 6-month mortality, LOS, and 7-day or 30-day readmission rates. HCAHPS scores remained unchanged (77 to 80% top box, P = 0.19), while resident evaluations of the rotation significantly improved (mean overall score 3.7 to 4.0, P = 0.03). CONCLUSIONS: Geographic cohorting was associated with increased resident satisfaction while achieving comparable patient outcomes to those of traditional hospital admitting models.

RESUMO

Although opioid agonist therapy (OAT) is associated with positive health outcomes, including improved HIV management, long-term retention in OAT remains low among patients with opioid use disorder (OUD). Using data from the Veterans Aging Cohort Study (VACS), we identify variables independently associated with OAT retention overall and by HIV status. Among 7,334 patients with OUD, 13.7% initiated OAT, and 27.8% were retained 12-months later. Likelihood of initiation and retention did not vary by HIV status. Variables associated with improved likelihood of retention included receiving buprenorphine (relative to methadone), receiving both buprenorphine and methadone at some point over the 12-month period, or diagnosis of HCV. History of homelessness was associated with a lower likelihood of retention. Predictors of retention were largely distinct between patients with HIV and patients without HIV. Findings highlight the need for clinical, systems, and research initiatives to better understand and improve OAT retention.

RESUMO

BACKGROUND: Medication for Opioid Use Disorder (MOUD) has been shown to be a safe, cost-effective intervention that successfully lowers risk of opioid overdose. However, access to and use of MOUD has been limited. Our objective was to explore attitudes, opinions, and beliefs regarding MOUD among healthcare and social service providers in a community highly impacted by the opioid overdose epidemic. METHODS: As part of a larger ethnographic study examining neighborhoods in Allegheny County, PA, with the highest opioid overdose death rates, semi-structured qualitative in-person and telephone interviews were conducted with forty-five providers treating persons with opioid use disorders in these communities. An open coding approach was used to code interview transcripts followed by thematic analysis. RESULTS: Three major themes were identified related to MOUD from the perspectives of our provider participants. Within a variety of health and substance use service roles and settings, provider reflections revealed: (1) different opinions about MOUD as a transition to abstinence or as a long-term treatment; (2) perceived lack of uniformity and dissemination of accurate information of MOUD care, permitting differences in care, and (3) observed barriers to entry and navigation of MOUD, including referrals as a "word-of-mouth insider system" and challenges of getting patients MOUD services when they need it. CONCLUSIONS: Even in communities hard hit by the opioid overdose epidemic, healthcare providers' disagreement about the standard of care for MOUD can be a relevant obstacle. These insights can inform efforts to improve MOUD treatment and access for people with opioid use disorders.

RESUMO

BACKGROUND: Pharmacists are positioned to play important roles in implementing evidence-based prevention and harm reduction approaches for opioid misuse and related health care outcomes such as human immunodeficiency virus (HIV) and hepatitis C. More research is needed to understand how best to facilitate harm reduction practices among pharmacists. OBJECTIVES: This hypothesis-generating study investigated (1) whether subgroups (latent classes) were observable among pharmacists based on self-reported comfort with specific harm reduction behaviors, (2) whether having reported expertise in key content areas was associated with any latent classes that might be identified, and (3) whether comfort and training were associated with actually having dispensed syringes for likely nonprescription drug use. METHODS: This was a statewide census of community managing pharmacists in Arizona conducted from December 2018 to May 2019. Participants reported their degree of comfort with 10 harm reduction behaviors, their expertise (e.g., recent continuing pharmacy education or specialization) in selected content areas, and their syringe dispensing behavior. Additional sociodemographic information was also collected. Subgroups related to harm reduction were computed using latent class analysis, and associations between study variables were assessed using the Fisher's exact tests. RESULTS: Data suggested the existence of 4 latent, comfort-based harm reduction classes: high comfort, moderate comfort, and clinical comfort, and opioid prevention only. Reported expertise in pre-exposure prophylaxis for HIV was likely associated with harm reduction class. However, class membership was not associated with reporting having dispensed nonprescription syringes, although the single comfort item for syringe dispensing, by itself, was associated therewith. CONCLUSION: Comfort with harm reduction likely clusters, so pharmacists may be broadly comfortable with topics or methods of harm reduction; however, comfort with a specific harm reduction pharmacy practice may be a better predictor of engaging in that behavior than harm reduction comfort class. In contrast, strategies to improve comfort, such as intervention development, might successfully be informed by pharmacists' latent class.

RESUMO

OBJECTIVE: Mebendazole and other anti-parasitic drugs are being used off-prescription based on social media and unofficial accounts of their anti-cancer activity. The purpose of this study was to conduct a controlled evaluation of mebendazole's therapeutic efficacy in cell culture and in vivo models of ovarian cancer. The majority of ovarian cancers harbor p53 null or missense mutations, therefore the effects of p53 mutations and a mutant p53 reactivator, PRIMA-1MET (APR246) on mebendazole activity were evaluated. METHODS: Mebendazole was evaluated in cisplatin-resistant high grade serous stage 3C ovarian cancer patient derived xenograft (PDX) models: PDX-0003 (p53 null) and PDX-0030 (p53 positive), and on ovarian cancer cell lines: MES-OV (p53 R282W), ES2 (p53 S241F), A2780 (p53 wild type), SKOV3 parental (p53 null) and isogenic sublines, SKOV3 R273H p53 and SKOV3 R248W p53. Drug synergy and mechanisms were evaluated in cell cultures using isobolograms, clonogenic assays and western blots. Prevention of tumor establishment was studied in a MES-OV orthotopic model. RESULTS: Mebendazole inhibited growth of ovarian cancer cell cultures at nanomolar concentrations and PDXs at doses up to 50 mg/kg, and reduced orthotopic tumor establishment at 50 mg/kg. The mechanism of mebendazole was associated with p53-independent induction of p21 and tubule depolymerization. PRIMA-1MET also inhibited tumor establishment and worked synergistically with mebendazole in cell culture to inhibit growth and induce intrinsic apoptosis through a p53- and tubule destabilization-independent mechanism. CONCLUSION: This work demonstrates the therapeutic potential of repurposing mebendazole and supports clinical development of mebendazole for ovarian cancer therapy and maintenance.

RESUMO

Current ovarian cancer maintenance therapy is limited by toxicity and no proven impact on overall survival. To study a maintenance strategy targeted at missense mutant p53, we hypothesized that the release of mutant p53 from mortalin inhibition by the SHetA2 drug combined with reactivation of mutant p53 with the PRIMA-1MET drug inhibits growth and tumor establishment synergistically in a mutant-p53 dependent manner. The Cancer Genome Atlas (TCGA) data and serous ovarian tumors were evaluated for TP53 and HSPA9/mortalin status. SHetA2 and PRIMA-1MET were tested in ovarian cancer cell lines and fallopian tube secretory epithelial cells using isobolograms, fluorescent cytometry, Western blots and ELISAs. Drugs were administered to mice after peritoneal injection of MESOV mutant p53 ovarian cancer cells and prior to tumor establishment, which was evaluated by logistic regression. Fifty-eight percent of TP53 mutations were missense and there were no mortalin mutations in TCGA high-grade serous ovarian cancers. Mortalin levels were sequentially increased in serous benign, borderline and carcinoma tumors. SHetA2 caused p53 nuclear and mitochondrial accumulation in cancer, but not in healthy, cells. Endogenous or exogenous mutant p53 increased SHetA2 resistance. PRIMA-1MET decreased this resistance and interacted synergistically with SHetA2 in mutant and wild type p53-expressing cell lines in association with elevated reactive oxygen species/ATP ratios. Tumor-free rates in animals were 0% (controls), 25% (PRIMA1MET ), 42% (SHetA2) and 67% (combination). SHetA2 (p = 0.004) and PRIMA1MET (p = 0.048) functioned additively in preventing tumor development with no observed toxicity. These results justify the development of SHetA2 and PRIMA-1MET alone and in combination for ovarian cancer maintenance therapy.

RESUMO

BACKGROUND: Mutual support groups (MSGs) are support systems for patients with substance use disorders (SUDs), yet medical residents lack awareness in the role MSGs play in addiction treatment. AIM: We developed an educational intervention to expose residents to MSGs and improve attitudes toward patients with SUD. SETTING: The study took place from October 2017 to March 2018 within a large academic medical center. PARTICIPANTS: First- to third-year internal medicine residents participated. PROGRAM DESCRIPTION: Residents attended a MSG meeting. They completed surveys pre- and post-meeting and attended a focus group debrief session. Focus group transcripts were coded and thematically analyzed. PROGRAM EVALUATION: Sixty-eight residents participated in the curriculum, 54 attended the focus group and 47 completed the pre- and post-survey. Qualitative themes included (1) appreciation for the sense of community at meetings, (2) improved perspective taking of patients with SUDs, (3) concern regarding religion, and (4) improved confidence in MSG referrals. Post-intervention, residents had more positive attitudes toward patients with SUD (p < 0.05 for 9 of 14 questions) and toward MSGs (p < 0.05 for 2 of 4 questions). DISCUSSION: Implementing an educational intervention on MSGs gives residents an experience that impacts attitudes toward patients with SUD and confidence with MSG referrals.

RESUMO

As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high dispersal capacity, such as migratory whales, where patterns of connectivity could change rapidly. Here we build on a previous long-term, large-scale collaboration on southern right whales (Eubalaena australis) to combine new (nnew) and published (npub) mitochondrial (mtDNA) and microsatellite genetic data from all major wintering grounds and, uniquely, the South Georgia (Islas Georgias del Sur: SG) feeding grounds. Specifically, we include data from Argentina (npub mtDNA/microsatellite = 208/46), Brazil (nnew mtDNA/microsatellite = 50/50), South Africa (nnew mtDNA/microsatellite = 66/77, npub mtDNA/microsatellite = 350/47), Chile-Peru (nnew mtDNA/microsatellite = 1/1), the Indo-Pacific (npub mtDNA/microsatellite = 769/126), and SG (npub mtDNA/microsatellite = 8/0, nnew mtDNA/microsatellite = 3/11) to investigate the position of previously unstudied habitats in the migratory network: Brazil, SG, and Chile-Peru. These new genetic data show connectivity between Brazil and Argentina, exemplified by weak genetic differentiation and the movement of 1 genetically identified individual between the South American grounds. The single sample from Chile-Peru had an mtDNA haplotype previously only observed in the Indo-Pacific and had a nuclear genotype that appeared admixed between the Indo-Pacific and South Atlantic, based on genetic clustering and assignment algorithms. The SG samples were clearly South Atlantic and were more similar to the South American than the South African wintering grounds. This study highlights how international collaborations are critical to provide context for emerging or recovering regions, like the SG feeding ground, as well as those that remain critically endangered, such as Chile-Peru.

RESUMO

Despite implementation of the Affordable Care Act (ACA), many Americans remain uninsured and receive care in free clinics. It is unknown what free clinic attendees in Pennsylvania know about health insurance expansion or what they perceive as barriers in enrolling in health insurance. The objective of this study was to assess the perceptions and experiences of free clinic patients from southwestern Pennsylvania when applying for health insurance after implementation of the ACA. We designed and implemented a survey of patients at three free clinics within Allegheny County, Pennsylvania from September 2016 to February 2017. Our survey included 22-items, 7 sociodemographic questions and 15 questions regarding the patient's health status and their perspectives related to obtaining health insurance. Data was obtained from 203 patient surveys; 110 (55.3%) of the respondents were men and 99 (48.8%) were African American. There were 48 respondents (24.1%) who did not report any income at the time of the study, and of those that did report an income, 92 (46.2%) respondents reported an income below 133% of the federal poverty level. The main barriers patients faced when applying for health insurance were: (1) lack of knowledge about health insurance (n = 127, 58.1%), (2) cost of health coverage (n = 85, 41.9%), (3) lack of resources (n = 83, 40.4%), and (4) lack of enrollment documentation (n = 43, 23.8%). Significant work is needed to better educate patients about their eligibility and options for health insurance. Free clinics can play a key role in eliminating barriers to health insurance enrollment.

RESUMO

PURPOSE: Implementation science offers methods to evaluate the translation of genomic medicine research into practice. The extent to which the National Institutes of Health (NIH) human genomics grant portfolio includes implementation science is unknown. This brief report's objective is to describe recently funded implementation science studies in genomic medicine in the NIH grant portfolio, and identify remaining gaps. METHODS: We identified investigator-initiated NIH research grants on implementation science in genomic medicine (funding initiated 2012-2016). A codebook was adapted from the literature, three authors coded grants, and descriptive statistics were calculated for each code. RESULTS: Forty-two grants fit the inclusion criteria (~1.75% of investigator-initiated genomics grants). The majority of included grants proposed qualitative and/or quantitative methods with cross-sectional study designs, and described clinical settings and primarily white, non-Hispanic study populations. Most grants were in oncology and examined genetic testing for risk assessment. Finally, grants lacked the use of implementation science frameworks, and most examined uptake of genomic medicine and/or assessed patient-centeredness. CONCLUSION: We identified large gaps in implementation science studies in genomic medicine in the funded NIH portfolio over the past 5 years. To move the genomics field forward, investigator-initiated research grants should employ rigorous implementation science methods within diverse settings and populations.

RESUMO

Primary care physicians are increasingly incorporating screening tools for substance use disorders (SUDs) and referral to treatment into their practice. Despite efforts to provide access to treatment, patients with SUDs remain at an increased risk of mortality, both from overdose and from general medical conditions. Advance care planning (ACP) is recommended for patients with chronic, progressive medical conditions such as malignancies or heart failure. Though SUDs are widely acknowledged to be chronic diseases associated with an increased risk of mortality, there has been little discussion on ACP in this population. ACP is a discussion regarding future care, often including selection of a surrogate decision-maker and completion of an advanced directive. ACP has been associated with better quality of end-of-life and care more consistent with patient preferences. Studies in other vulnerable populations have shown that marginalized and high-risk individuals may be less likely to receive ACP. Similarly, patients with SUDs may employ different decision-makers than that defined by law (i.e., friend vs. family member), increasing the importance of discussing patient values and social structure. Physicians should routinely conduct ACP conversations with patients with SUDs, especially those with chronic, progressive medical conditions and/or severe, uncontrolled substance use disorders.

RESUMO

BACKGROUND: Community pharmacies are important for health access by rural populations and those who do not have optimum access to the health system, because they provide myriad health services and are found in most communities. This includes the sale of non-prescription syringes, a practice that is legal in the USA in all but two states. However, people who inject drugs (PWID) face significant barriers accessing sterile syringes, particularly in states without laws allowing syringe services programming. To our knowledge, no recent studies of pharmacy-based syringe purchase experience have been conducted in communities that are both rural and urban, and none in the Southwestern US. This study seeks to understand the experience of retail pharmacy syringe purchase in Arizona by PWID. METHODS: An interview study was conducted between August and December 2018 with 37 people living in 3 rural and 2 urban Arizona counties who identified as current or former users of injection drugs. Coding was both a priori and emergent, focusing on syringe access through pharmacies, pharmacy experiences generally, experiences of stigma, and recommendations for harm reduction services delivered by pharmacies. RESULTS: All participants reported being refused syringe purchase at pharmacies. Six themes emerged about syringe purchase: (1) experience of stigma and judgment by pharmacy staff, (2) feelings of internalized stigma, (3) inconsistent sales outcomes at the same pharmacy or pharmacy chain, (4) pharmacies as last resort for syringes, (5) fear of arrest for syringe possession, and (6) health risks resulting from syringe refusal. CONCLUSIONS: Non-prescription syringe sales in community pharmacies are a missed opportunity to improve the health of PWID by reducing syringe sharing and reuse. Yet, current pharmacy syringe sales refusal and stigmatization by staff suggest that pharmacy-level interventions will be necessary to impact pharmacy practice. Lack of access to sterile syringes reinforces health risk behaviors among PWID. Retail syringe sales at pharmacies remain an important, yet barrier-laden, element of a comprehensive public health response to reduce HIV and hepatitis C among PWID. Future studies should test multilevel evidence-based interventions to decrease staff discrimination and stigma and increase syringe sales.

RESUMO

PURPOSE: The objective of this study was to identify trends and gaps in the field of implementation science in genomic medicine. METHODS: We conducted a literature review using the Centers for Disease Control and Prevention's Public Health Genomics Knowledge Base to examine the current literature in the field of implementation science in genomic medicine. We selected original research articles based on specific inclusion criteria and then abstracted information about study design, genomic medicine, and implementation outcomes. Data were aggregated, and trends and gaps in the literature were discussed. RESULTS: Our final review encompassed 283 articles published in 2014, the majority of which described uptake (35.7%, n = 101) and preferences (36.4%, n = 103) regarding genomic technologies, particularly oncology (35%, n = 99). Key study design elements, such as racial/ethnic composition of study populations, were underreported in studies. Few studies incorporated implementation science theoretical frameworks, sustainability measures, or capacity building. CONCLUSION: Although genomic discovery provides the potential for population health benefit, the current knowledge base around implementation to turn this promise into a reality is severely limited. Current gaps in the literature demonstrate a need to apply implementation science principles to genomic medicine in order to deliver on the promise of precision medicine.Genet Med advance online publication 12 January 2017.

RESUMO

BACKGROUND: It is unknown whether there are neurobiologic differences between various anxiety and depressive disorders, or whether they are characterized by shared neurobiologic variation that cuts across diagnostic boundaries. For instance, multiple anxiety disorders and depression may be characterized by abnormalities in blood oxygen-level dependent (BOLD) response during the processing of affective scenes and faces. To interrogate the shared or unique nature of these aberrations, research that examines the influence of transdiagnostic, dimensional predictors across multiple diagnoses is needed. METHODS: One hundred ninety-nine individuals, 142 with primary diagnoses of social anxiety disorder (SAD), generalized anxiety disorder (GAD), or major depressive disorder (MDD) and 57 free from psychiatric diagnoses (healthy controls, HCs), performed a face-matching task involving fearful, angry, and happy faces (and geometric shapes) while undergoing functional magnetic resonance imaging. RESULTS: Across the three primary diagnoses, anxiety symptom scores were associated with increased Angry > Shapes activation in the bilateral insula, anterior/midcingulate, and dorsolateral prefrontal cortex (dlPFC), while depressive symptoms were associated with reduced dlPFC activation for Angry > Shapes. Patient > HC differences were limited to non a priori regions, and no differences in BOLD activation were observed between diagnostic groups. CONCLUSIONS: (1) Activation in paralimbic, cingulate, and lateral prefrontal regions in response to angry faces is associated with transdiagnostic anxiety and depressive symptomatology. (2) Anxiety and depressive symptoms may exert opposing influences on lateral prefrontal activation. (3) Abnormal threat processing in GAD, SAD, and MDD may reflect shared neural dysfunction that varies with symptom load.
