A novel multifamily treatment targeting symptoms related to Latinx caregiver deportation.

OBJECTIVE: Latinx youth who have experienced caregiver deportation show higher rates of posttraumatic stress disorder (PTSD) and internalizing symptoms compared to Latinx youth who have not. Thus, there is a need for culturally and linguistically appropriate therapeutic approaches to address psychiatric needs related to caregiver deportation. Positive Adaptations for Trauma and Healing (PATH) is a manualized 10-week group therapy for Latinx youth and their caregivers that integrates trauma-informed interventions with positive psychology and resilience interventions. The present study examined PATH for reducing trauma symptomatology for Latinx youth who endured at least three traumatic experiences in their caregiving system as well as differences for Latinx youth who experienced their caregiver's deportation. METHOD: Self-identified Latinx youth (N = 31) and their Spanish-speaking caregivers were recruited from two urban hospitals. All youth experienced three or more traumatic events. Pre- to postintervention mean change was measured with t tests; mixed-effects analysis of variance assessed whether the program was feasible for youth who had experienced a caregiver deportation versus Latinx youth who did not. RESULTS: Assessment with the Trauma Symptom Checklist and the UCLA PTSD Index for Youth showed statistically significant reductions on Anxiety, Depression, Anger, and PTSD subscales. Latinx youth who experienced a caregiver's deportation exhibited larger reductions in anger symptoms and PTSD symptoms. CONCLUSION: Study results suggest that the novel group therapy intervention was feasible and acceptable for Latinx youth and their caregivers. Despite a small sample size, the intervention proved feasible for Latinx youth who experienced caregiver deportation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The differential impact of COVID-19 on mental health: Implications of ethnicity, sexual orientation, and disability status in the United States.

The COVID-19 pandemic's effects on mental health interact with preexisting health risks and disparities to impact varying populations differently. This study explored the relationship between demographic variables (e.g., ethnicity, sexual orientation, and disability status), distress and mental health (e.g., depression, anxiety, somatic complaints, and pandemic distress), and vulnerability factors for COVID-19 (e.g., personal health vulnerabilities, community members' health vulnerabilities, and environmental exposure risks at work or home). An online cross-sectional study was conducted from 18 June to 17 July 2020, reflecting the impact of early phase COVID-19 pandemic and related shelter-in-place measures in the United States. Participants were adults residing in the United States (N = 594), with substantial subsamples (N ≥ 70) of American Indian, Asian American, African-American, and Hispanic and/or Latinx participants, as well as people with disabilities and sexual minorities. Outcomes measured were depression, hopelessness, somatic complaints, anxiety-related disorders, locus of control (LOC), and a novel measure of pandemic-related distress. Data were analyzed using analyses of covariance (ANCOVA), chi-square test, and correlation coefficients. Generally, younger individuals, and those with less financial power-across all identities-suffered more distress. When controlling for age, lower financial power was associated with higher scores on the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R; r = -0.21, p = < 0.001), Beck Hopelessness Scale (BHS; r = -0.17, p < 0.001), Patient Health Questionnaire-15 (PHQ-15; r = -0.09, p = 0.01), Screen for Child Anxiety Related Emotional Disorders for Adults Panic Disorder (SCARED-A PD; r = -0.14, p < 0.001), SCARED-A generalized anxiety disorder (GAD; r = -0.13, p = 0.002), SCARED-A obsessive-compulsive disorder (OCD; r = -0.08, p = 0.04), and the COVID-19 Pandemic Distress restriction/disconnection scale (C19PDS; r = -0.10, p = 0.009). In addition, disparities were found, in general, for marginalized identities by gender, sexual orientation, and disability status. Importantly, each ethnicity subsample showed a unique pattern of relationships between COVID-19 risk variables and mental health symptoms. The results support the hypothesis that any pandemic may amplify preexisting social and financial disparities. Overall, interventions at the clinical, governmental, or health equity level should take into consideration the needs of vulnerable groups.

A Formal Palliative Care Service Improves the Quality of Care in Patients with Stage IV Cancer and Bowel Obstruction.

BACKGROUND: Patients with stage IV cancer and bowel obstruction present a complicated management problem. The aim of this study was to evaluate the role of the palliative care service (PC) in the management of this complex disease process. METHODS: A retrospective analysis was conducted of all patients admitted to Roswell Park Cancer Institute with stage IV cancer and bowel obstruction from 2009 to 2012 after the institution of a formal PC. This cohort was matched to similar patients from 2005 to 2008 (no palliative care service or NPC). Patient characteristics and outcomes included baseline demographics, comorbid conditions, do-not-resuscitate (DNR) status, laboratory parameters, medical and surgical management, length of stay, symptom relief, and disposition status. RESULTS: A total of 19 patients were identified in the PC group. Based on the PC group baseline characteristics, 19 patients were identified for the NPC group using matched values. Regarding outcomes, there were significant differences in the medication regimens (narcotics, octreotide, and Decadron) between the 2 groups. In the PC group, 14 of 19 patients showed improvement compared to 9 of 19 in the NPC group. Nearly 60% of patients in the PC group had a formal DNR order versus 10.5% in NPC ( P = .002). A significantly higher percentage of patients were discharged to hospice in the PC group (47.4% vs 0.0%, P = .006). CONCLUSION: Palliative care consultation improves the quality of care for patients with stage IV cancer and bowel obstruction, with particular benefits in symptom management, end-of-life discussion, and disposition to hospice.

The Current State of Palliative Care for Patients Cared for at Leading US Cancer Centers: The 2015 NCCN Palliative Care Survey.

BACKGROUND: ASCO and IOM recommend palliative care (PC) across health care settings for patients with serious illnesses, including cancer. This study provides an overview of the current availability, structure, and basic quality of PC services within NCCN Member Institutions. METHODS: A PC survey was developed by NCCN staff and a working group of PC experts from 11 NCCN Member Institutions under the auspices of the NCCN Best Practices Committee. The survey was piloted and refined by 3 working group members and sent electronically to all 26 NCCN Member Institutions. NCCN staff and working group leaders analyzed the survey data. RESULTS: A total of 22 of 26 institutions responded (85%). All respondents (100%) reported an inpatient PC consult service (staffed by an average of 6.8 full-time equivalents [FTEs], seeing 1,031 consults/year with an average length of stay [LOS] of 10 days). A total of 91% of respondents had clinic-based PC (with an average of 469 consults/year, staffed by an average of 6.8 FTEs, and a 17-day wait time). For clinics, a comanagement care delivery model was more common than strict consultation. Home-based PC (23%) and inpatient PC units (32%) were less prevalent. Notably, 80% of institutions reported insufficient PC capacity compared with demand. Across PC settings, referrals for patients with solid tumors were more common than for hematologic malignancies. Automatic or "triggered" referrals were rare. The most common services provided were symptom management (100%) and advance care planning (96%). Most programs were funded through fee-for-service billing and institutional support. Partnerships with accountable care organizations and bundled payment arrangements were infrequent. PC program data collection and institutional funding for PC research were variable across institutions. CONCLUSIONS: Despite the prevalence of PC inpatient and clinic services among participating NCCN Member Institutions, PC demand still exceeds capacity. Opportunities exist for expansion of home-based PC and inpatient PC units, optimizing referrals, research, and payer collaborations.

Palliative Care Version 1.2016.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. The NCCN Guidelines are intended to provide guidance to the primary oncology team on the integration of palliative care into oncology. The NCCN Palliative Care Panel's recommendations seek to ensure that each patient experiences the best quality of life possible throughout the illness trajectory. Accordingly, the NCCN Guidelines outline best practices for screening, assessment, palliative care interventions, reassessment, and after-death care.

Cancer-Related Fatigue, Version 2.2015.

Cancer-related fatigue is defined as a distressing, persistent, subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning. It is one of the most common side effects in patients with cancer. Fatigue has been shown to be a consequence of active treatment, but it may also persist into posttreatment periods. Furthermore, difficulties in end-of-life care can be compounded by fatigue. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Cancer-Related Fatigue provide guidance on screening for fatigue and recommendations for interventions based on the stage of treatment. Interventions may include education and counseling, general strategies for the management of fatigue, and specific nonpharmacologic and pharmacologic interventions. Fatigue is a frequently underreported complication in patients with cancer and, when reported, is responsible for reduced quality of life. Therefore, routine screening to identify fatigue is an important component in improving the quality of life for patients living with cancer.

Palliative care, Version 1.2014. Featured updates to the NCCN Guidelines.

The NCCN Guidelines for Palliative Care provide interdisciplinary recommendations on palliative care for patients with cancer. These NCCN Guidelines Insights summarize the NCCN panel's discussions and guideline updates from 2013 and 2014. These include modifications/additions to palliative care screening and assessment protocols, new considerations for discussing the benefits and risks of anticancer therapy, and approaches to advance care planning. Recent updates focus on enhanced patient-centered care and seek to promote earlier integration of palliative care and advance care planning in oncology.

Management of bowel obstruction in patients with stage IV cancer: predictors of outcome after surgery.

BACKGROUND: Patients with stage IV cancer and bowel obstruction (BO) present a complicated management problem. We sought to determine if specific parameters could predict outcome after surgery. METHODS: Records of patients with stage IV cancer and BO treated from 1991 to 2008 were reviewed. For surgical patients, 30-day morbidity and 90-day mortality were assessed using exact multivariable logistic regression methods. RESULTS: Of 198 patients, 132 (66.7%) underwent surgery, 66 medical treatment alone, and demographics were similar. A total of 41 patients (20.7%) were diagnosed with stage IV cancer and BO synchronously, all treated surgically; the remaining presented metachronously. Medically managed patients were more likely to have received chemotherapy in the 30 days prior to BO (45 of 66 [68.2%] vs 40 of 132 [30.3%], p < .01). In the surgical group, 30-day morbidity was 35.6%, while 90-day mortality was 42.3%. Median overall survival for synchronous patients was 14.1 months (95% confidence interval [95% CI] 7.6-23.2), and 3.7 months (95% CI 2.5-5.2) and 3.6 months (95% CI 1.5-5.2) for metachronous patients treated surgically and medically, respectively. A multivariate model for 90-day surgical mortality identified low serum albumin, metachronous presentation, and ECOG > 1 as predictors of death (p < .05). A model for 30-day surgical morbidity yielded low hematocrit as a predictive factor (p < .05). CONCLUSIONS: This cohort identifies characteristics indicative of morbidity and mortality in stage IV cancer and BO. Low serum albumin, ECOG > 1, and metachronous presentation predicted for 90-day surgical mortality. These data suggest factors that can be used to frame treatment discussion plans with patients.

Controversies in acute stroke treatment.

The evidence base supporting the management of patients with acute stroke is evolving at a rapid rate, as new methods that aim to reduce disability and death from stroke are explored. Intravenous tissue plasminogen activator remains the only treatment shown in numerous studies to reduce disability 3 months after stroke with no increase in the risk of death and a relatively minor rate of symptomatic intracerebral hemorrhage complications. Despite these findings, health care providers have been slow to adopt this evidence-based treatment, which results in many patients experiencing disability caused by stroke. Numerous controversies exist related to the management of patients with acute stroke, including the use of tissue plasminogen activator, positioning and early mobility, blood pressure lowering in acute intracerebral hemorrhage, and even the use of innovative advanced practice nurse-led stroke treatment teams, with varying amounts of evidence available to provide direction. This article explores controversies associated with both approved and evolving treatments for ischemic and hemorrhagic stroke and makes recommendations for practice on the basis of the body of existing evidence, with an aim to improve the delivery of acute stroke treatment.

Proteomic analyses of the Xiphophorus Gordon-Kosswig melanoma model.

Interspecies hybridization between the platyfish X. maculatus Jp 163 A, and the swordtail X. helleri (Sarabia), generates F(1) hybrids with pronounced melanin pigmentation. Backcrossing of F(1) hybrids with the X. helleri parent results in 25% of progeny that will spontaneously develop melanoma. We have applied proteomic methods to this Gordon-Kosswig (G-K) melanoma model to identify candidate proteins that exhibit modulated expression in fin tissue due to interspecies hybridization and progression of hybrid tissues to spontaneous melanoma. Difference Gel Electrophoresis (DIGE) was used to minimize the variability commonly observed in quantitative analyses of comparative protein samples. Following identification of up- or down-regulated protein expression by DIGE, candidate protein spots were identified by mass spectrometric sequencing. Several protein expression differences displayed in interspecies hybrids were identified and compared to distinct differences that occur upon backcrossing and progression to melanoma. These studies are important for the identification of distinct biochemical pathways involved in the variety of Xiphophorus interspecies hybrid tumor models.

Detection of hypoxia-related proteins in medaka (Oryzias latipes) brain tissue by difference gel electrophoresis and de novo sequencing of 4-sulfophenyl isothiocyanate-derivatized peptides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Two-dimensional fluorescence-based difference gel electrophoresis (DIGE) was used in combination with matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS) to identify a set of hypoxia-related biomarker proteins in medaka (Oryzias latipes) brain tissue. Each of the proteins were identified via de novo sequencing of tryptic peptides derivatized with 4-sulfophenyl isothiocyanate (SPITC), which N-terminally sulfonates peptides and promotes facile post-source decay peptide fragmentation, resulting in greatly simplified spectra consisting mainly of y-series fragment ions. We also report that addition of the non-ionic surfactant n-octyl-beta-d-glucopyranoside significantly improves SPITC-derivatized peptide recoveries. In addition, we found that a MALDI matrix consisting of the sodium-tolerant matrix 2,4,6-trihydroxyacetophenone, diammonium citrate, and alpha-cyano-4-hydroxycinnamic acid also improves ionization of SPITC-peptides, presumably by reducing ionization suppression effects from matrix contaminants, especially sodium cations. The DIGE experiments and analyses resulted in detection of six abundant proteins and related isozymes up-regulated (>1.49, p<0.005) in hypoxic medaka brain tissues, including two hemoglobin beta subunit forms, four carbonic anhydrase 2 forms, calbindin, aldolase, succinate dehydrogenase, and glutathione-S-transferase.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry of 4-sulfophenyl isothiocyanate-derivatized peptides on AnchorChip sample supports using the sodium-tolerant matrix 2,4,6-trihydroxyacetophenone and diammonium citrate.

The reagent 4-sulfophenyl isothiocyanate (SPITC) is an effective, stable, and inexpensive alternative to commercially available reagents used in the N-terminal sulfonation of peptides for enhanced postsource decay (PSD) in matrix-assisted laser desorption/ionization time-of-flight mass spectrometric (MALDI-TOFMS) analyses. However, suppression of ionization of sulfonated peptides due to sample and matrix contaminants such as sodium can be a problem when using prestructured MALDI target sample supports, such as the Bruker Daltonics AnchorChip. We show that use of the salt-tolerant matrix 2,4,6-trihydroxyacetophenone containing diammonium citrate (THAP/DAC) as an alternative to alpha-cyanohydroxycinnamic acid (HCCA) reduces the need for extensive washing of ZipTip-bound peptides or additional on-target sample clean-up steps. Use of the THAP/DAC matrix results in selective ionization of sulfonated peptides with greater peptide coverage, as well as detection of higher mass derivatized peptides, than was observed for HCCA or THAP alone. The THAP/DAC matrix is quite tolerant of sodium contamination, with SPITC-peptides detectable in preparations containing up to 50 mM NaCl. In addition, THAP/DAC matrix was found to promote efficient PSD fragmentation of sulfonated peptides. We demonstrated the utility of using the THAP/DAC MALDI matrix for peptide sequencing with DNA polymerase beta tryptic peptide mixture, as well as tryptic peptides derived from Xiphophorus maculatus brain extract proteins previously separated by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE).
