Clinical relevance of HLA-DQ eplet mismatch and maintenance immunosuppression with risk of allosensitization after kidney transplant failure.

The optimal immunosuppression management in patients with a failed kidney transplant remains uncertain. This study analyzed the association of class II HLA eplet mismatches and maintenance immunosuppression with allosensitization after graft failure in a well characterized cohort of 21 patients who failed a first kidney transplant. A clinically meaningful increase in cPRA in this study was defined as the cPRA that resulted in 50% reduction in the compatible donor pool measured from the time of transplant failure until the time of repeat transplantation, death, or end of study. The median cPRA at the time of failure was 12.13% (interquartile ranges = 0.00%, 83.72%) which increased to 62.76% (IQR = 4.34%, 99.18%) during the median follow-up of 27 (IQR = 18, 39) months. High HLA-DQ eplet mismatches were significantly associated with an increased risk of developing a clinically meaningful increase in cPRA (p = 0.02) and de novo DQ donor-specific antibody against the failed allograft (p = 0.02). We did not observe these associations in patients with high HLA-DR eplet mismatches. Most of the patients (88%) with a clinically meaningful increase in cPRA had both a high DQ eplet mismatch and a reduction in their immunosuppression, suggesting the association is modified by immunosuppression. The findings suggest HLA-DQ eplet mismatch analysis may serve as a useful tool to guide future clinical studies and trials which assess the management of immunosuppression in transplant failure patients who are repeat transplant candidates.

From racial awakening to collective action: Asian Americans' pathways to activism and benevolent support during COVID-19.

OBJECTIVES: In response to increased anti-Asian discrimination and violence during the COVID-19 pandemic, this study examined pathways from discrimination experiences to own-group collective action in a diverse sample of 689 Asian Americans. METHOD: Informed by theories of ethnoracial identity, critical consciousness, and collective action and utilizing structural equation modeling, we examined the associations among discrimination, psychological distress, critical awareness and motivation (CAM) to resist racism, and two types of own-group collective action: political activism and benevolent support. Multigroup invariance tests also examined whether these associations differed by ethnic subgroup, immigrant generation, and age. RESULTS: Results supported our integrated model in which distress mediated the relationship between discrimination and CAM, and CAM mediated the relationship between discrimination and collective action. The structural pathways from discrimination to own-group collective action generally did not differ by ethnic subgroup and immigrant generation, although path coefficients for the effect of discrimination on distress did vary by age (p < .01). Further, discrimination did not appear to have the same catalyzing effect on CAM for South and Southeast Asians compared to East Asians. CONCLUSIONS: While anti-Asian discrimination was associated with both distress and engagement in collective action during the COVID-19 pandemic, group differences in mediational processes highlight the importance of disaggregating analyses to explore both similarities and differences in Asian Americans' responses to discrimination.

Does Mindfulness Improve Intergroup Bias, Internalized Bias, and Anti-Bias Outcomes?: A Meta-Analysis of the Evidence and Agenda for Future Research.

Whereas mindfulness has been shown to enhance personal well-being, studies suggest it may also benefit intergroup dynamics. Using an integrative conceptual model, this meta-analysis examined associations between mindfulness and (a) different manifestations of bias (implicit/explicit attitudes, affect, behavior) directed toward (b) different bias targets (outgroup or ingroup, e.g., internalized bias), by (c) intergroup orientation (toward bias or anti-bias). Of 70 samples, 42 (N = 3,229) assessed mindfulness-based interventions (MBIs) and 30 (N = 6,002) were correlational studies. Results showed a medium-sized negative effect of MBIs on bias outcomes, g = -0.56, 95% confidence interval [-0.72, -0.40]; I(2;3)2: 0.39; 0.48, and a small-to-medium negative effect between mindfulness and bias for correlational studies, r = -0.17 [-0.27, -0.03]; I(2;3)2: 0.11; 0.83. Effects were comparable for intergroup bias and internalized bias. We conclude by identifying gaps in the evidence base to guide future research.

G protein-coupled receptor modulation of striatal dopamine transmission: Implications for psychoactive drug effects.

Dopamine transmission in the striatum is a critical mediator of the rewarding and reinforcing effects of commonly misused psychoactive drugs. G protein-coupled receptors (GPCRs) that bind a variety of neuromodulators including dopamine, endocannabinoids, acetylcholine and endogenous opioid peptides regulate dopamine release by acting on several components of dopaminergic circuitry. Striatal dopamine release can be driven by both somatic action potential firing and local mechanisms that depend on acetylcholine released from striatal cholinergic interneurons. GPCRs that primarily regulate somatic firing of dopamine neurons via direct effects or modulation of synaptic inputs are likely to affect distinct aspects of behaviour and psychoactive drug actions compared with those GPCRs that primarily regulate local acetylcholine-dependent dopamine release in striatal regions. This review will highlight mechanisms by which GPCRs modulate dopaminergic transmission and the relevance of these findings to psychoactive drug effects on physiology and behaviour.

Erythrocytosis and thrombotic events in kidney transplant recipients prescribed a sodium glucose cotransport-2 inhibitor.

INTRODUCTION: The safety and efficacy of sodium glucose cotransport-2 inhibitors (SGLT2i) in kidney transplant recipients remains uncertain. Transplant recipients may be at risk of thrombosis because of post-transplant erythrocytosis and SGLT2i are associated with an increase in hematocrit. METHODS: We determined SGLT2i use, the change in hematocrit and incidence of thrombotic events in kidney transplant recipients in 1700 prevalent patients in our center. RESULTS: Among the 42 patients treated with SGLT2i, the mean pre-transplant hematocrit was 31%, and none of the patients had a hematocrit ≥50%. The mean percent change in hematocrit measured at an average of 53 days after initiation of an SGLT2i was 11% and four patients (10%) had a hematocrit ≥ 50%. The mean hematocrit measured 3 months after treatment was 42% and two patients (5%) had a hematocrit ≥50%. One patient had a cerebellar stroke 14 months post-SGLT2i initiation when the hemoglobin was 173 grams/liter, and the hematocrit was 52%. CONCLUSIONS: All patients had a sustained increase in hematocrit 3 months after SGLT2i treatment. Hematocrit ≥50% occurred in 10%, and one patient had a thrombotic event that may or may not have been related to an increase in hematocrit. Clinicians may consider monitoring for erythrocytosis after starting and SGLT2i in kidney transplant recipients.

The Benefits of Preemptive Transplantation Using High-Kidney Donor Profile Index Kidneys.

BACKGROUND: The Kidney Donor Profile Index (KDPI) is a percentile score summarizing the likelihood of allograft failure: A KDPI ≥85% is associated with shorter allograft survival, and 50% of these donated kidneys are not currently used for transplantation. Preemptive transplantation (transplantation without prior maintenance dialysis) is associated with longer allograft survival than transplantation after dialysis; however, it is unknown whether this benefit extends to high-KDPI transplants. The objective of this analysis was to determine whether the benefit of preemptive transplantation extends to recipients of transplants with a KDPI ≥85%. METHODS: This retrospective cohort study compared the post-transplant outcomes of preemptive and nonpreemptive deceased donor kidney transplants using data from the Scientific Registry of Transplant Recipients. 120,091 patients who received their first, kidney-only transplant between January 1, 2005, and December 31, 2017, were studied, including 23,211 with KDPI ≥85%. Of this cohort, 12,331 patients received a transplant preemptively. Time-to-event models for the outcomes of allograft loss from any cause, death-censored graft loss, and death with a functioning transplant were performed. RESULTS: Compared with recipients of nonpreemptive transplants with a KDPI of 0%-20% as the reference group, the risk of allograft loss from any cause in recipients of a preemptive transplant with KDPI ≥85% (hazard ratio [HR], 1.51; 95% confidence interval [CI], 1.39 to 1.64) was lower than that in recipients of nonpreemptive transplant with a KDPI ≥85% (HR, 2.39; 95% CI, 2.21 to 2.58) and similar to that of recipients of a nonpreemptive transplant with a KDPI of 51%-84% (HR, 1.61; 95% CI, 1.52 to 1.70). CONCLUSIONS: Preemptive transplantation is associated with a lower risk of allograft failure, irrespective of KDPI, and preemptive transplants with KDPI ≥85% have comparable outcomes with nonpreemptive transplants with KDPI 51%-84%.

The living kidney donor profile index fails to discriminate allograft survival: implications for its use in kidney paired donation programs.

The inclusion of blood group- and human leukocyte antigen-compatible donor and recipient pairs (CPs) in kidney paired donation (KPD) programs is a novel strategy to increase living donor (LD) transplantation. Transplantation from a donor with a better Living Donor Kidney Profile Index (LKDPI) may encourage CP participation in KPD programs. We undertook parallel analyses using data from the Scientific Registry of Transplant Recipients and the Australia and New Zealand Dialysis and Transplant Registry to determine whether the LKDPI discriminates death-censored graft survival (DCGS) between LDs. Discrimination was assessed by the following: (1) the change in the Harrell C statistic with the sequential addition of variables in the LKDPI equation to reference models that included only recipient factors and (2) whether the LKDPI discriminated DCGS among pairs of prognosis-matched LD recipients. The addition of the LKDPI to reference models based on recipient variables increased the C statistic by only 0.02. Among prognosis-matched pairs, the C statistic in Cox models to determine the association of the LKDPI with DCGS was no better than chance alone (0.51 in the Scientific Registry of Transplant Recipient and 0.54 in the Australia and New Zealand Dialysis and Transplant Registry cohorts). We conclude that the LKDPI does not discriminate DCGS and should not be used to promote CP participation in KPD programs.

Factors Contributing to West Indian American Depression.

This study explored factors that mediate the relationship between subjective wellbeing and depression in a sample of West Indian American immigrants. An intersectional theoretical framework was used to identify the relative contribution of psychological stressors-perceived discrimination, financial strain and acculturative stress-that mediate the relationship between subjective wellbeing and depression. A geographically diverse sample was recruited by an online survey (N = 255), consisting of 138 men, 115 women, 173 Indo-West Indians and 82 Afro-West Indians. Path analysis was used to identify the relative contribution of psychological stressors. Acculturative stress and financial strain were both statistically significant predictors of depression. Financial strain was identified as the major mediator between subjective wellbeing and depression in West Indian Americans. West Indian Americans are vulnerable to financial strain and acculturative stress. These sources of psychological stress are important contributors to depression in the community. More research is needed to clarify these relationships.

Disaggregating the data: Diversity of COVID-19 stressors, discrimination, and mental health among Asian American communities.

Much of the public discourse as well as research regarding the negative impact of COVID-19-related anti-Asian discrimination has been conducted at the broad racial group level, yet data aggregation masks critical points of diversity among Asian Americans. We conducted an online survey of 620 Asian American adults in December 2020 and examined whether there were any demographic differences-including by ethnic subgroup and Chinese street race (being Chinese or being mistaken as Chinese)-in their experiences of COVID-19-related stress, direct and vicarious discrimination, and psychological outcomes. Our analyses found that younger age was correlated with higher reports of pandemic stress, discrimination, distress, and worry. Female and U.S.-born participants reported higher levels of pandemic stress and vicarious discrimination, but there were no gender or nativity differences in levels of direct discrimination. Being uninsured was also related to higher levels of pandemic stress, discrimination, and distress. East Asian Americans reported significantly lower frequencies of direct anti-Asian discrimination than did South Asian or Southeast Asian Americans, but the ethnic subgroups did not differ in their reports of vicarious discrimination. Of note, Chinese street race was not associated with either direct or vicarious discrimination. Separate hierarchical regression analyses for East Asian, South Asian, and Southeast Asian participants revealed that, regardless of ethnicity, racial discrimination significantly contributed to psychological distress and worry beyond the effects of pandemic stress. However, the three groups varied in the demographic indicators and COVID-19 stressors that were associated with psychological outcomes. Pandemic stress was more strongly associated with negative outcomes among South Asian Americans than East Asian and Southeast Asian Americans, and neither direct nor vicarious discrimination were associated with mental health among South Asian Americans. Direct discrimination, compared to vicarious discrimination, was a particularly robust predictor of both distress and worry among East Asian Americans. For Southeast Asian Americans, direct discrimination significantly predicted higher levels of distress, whereas vicarious discrimination predicted higher levels of worry. Vicarious discrimination was not significantly related to distress across ethnic subgroups. Results suggest that practitioners and policy makers would benefit from attending to these within-group differences in Asian Americans' experiences during the pandemic.

ABO-adjusted calculated panel reactive antibody (cPRA): A unified metric for immunologic compatibility in kidney transplantation.

Implementation of the kidney allocation system in 2014 greatly reduced access disparity due to human leukocyte antigen (HLA) sensitization. To address persistent disparity related to candidate ABO blood groups, herein we propose a novel metric termed "ABO-adjusted cPRA," which simultaneously considers the impact of candidate HLA and ABO sensitization on the same scale. An ethnic-weighted ABO-adjusted cPRA value was computed for 190 467 candidates on the kidney waitlist by combining candidate's conventional HLA cPRA with the remaining fraction of HLA-compatible donors that are ABO-incompatible. Consideration of ABO sensitization resulted in higher ABO-adjusted cPRA relative to conventional cPRA by HLA alone, except for AB candidates since they are not ABO-sensitized. Within cPRA Point Group = 99%, 43% of the candidates moved up to ABO-adjusted cPRA Point Group = 100%, though this proportion varied substantially by candidate blood group. Nearly all O and most B candidates would have elevated ABO-adjusted cPRA values above this policy threshold for allocation priority, but relatively few A candidates displayed this shift. Overall, ABO-adjusted cPRA more accurately measures the proportion of immune-compatible donors compared with conventional HLA cPRA, especially for highly sensitized candidates. Implementation of this novel metric could enable the development of allocation policies permitting more ABO-compatible transplants without compromising equity.

Transplantation of Patients With Long Dialysis Vintage in the Current Deceased Donor Kidney Allocation System (KAS).

RATIONALE & OBJECTIVE: In 2014 the wait-time calculation for deceased donor kidney transplantation in the United States was changed from the date of first waitlisting to the date of first maintenance dialysis treatment with the aim of minimizing disparities in access to transplantation. This study examined the impact of this policy on access to transplantation, patient survival, and transplant outcomes among patients treated with maintenance dialysis for a prolonged duration before waitlisting. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Patients identified in the US Renal Data System between 2008 and 2018 aged 18-70 years and in the 95th percentile of dialysis treatment duration (≥6.5 years) before waitlisting. EXPOSURE: Waitlisting for transplantation before versus after implementation of the policy. OUTCOME: Time from date of waitlisting to deceased donor transplantation and death, and from date of transplantation to all cause graft loss. ANALYTICAL APPROACH: Univariate and multivariable time to event analyses. RESULTS: Patients waitlisted after the policy change had a higher likelihood of deceased donor transplantation (HR, 3.12 [95% CI, 2.90-3.37]) and lower risk of death (HR, 0.74 [95% CI, 0.63-0.87]). The risk of graft loss was lower in the post-kidney allocation system (KAS) cohort (HR, 0.66 [95% CI, 0.55-0.80]). The proportion of adult patients treated with dialysis ≥6.5 years who were never waitlisted for transplantation remained high (73%) and did not decrease after the policy implementation. LIMITATIONS: Cannot determine causality in this observational study. CONCLUSIONS: The policy change was associated with an increase in deceased donor transplantation and marked improvement in patient survival for patients waitlisted after long periods of dialysis treatment without decreasing the utility of available deceased donor kidney supply. The policy was not associated with increased waitlisting of this disadvantaged population.

Use and Outcomes of Induction Therapy in Well-Matched Kidney Transplant Recipients.

BACKGROUND AND OBJECTIVES: The optimal induction treatment in low-immune risk kidney transplant recipients is uncertain. We therefore investigated the use and outcomes of induction immunosuppression in a low-risk cohort of patients who were well matched with their donor at HLA-A, -B, -DR, -DQB1 on the basis of serologic typing. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Our study was an observational study of first adult kidney-only transplant recipients in the United States recorded by the Organ Procurement and Transplant Network. RESULTS: Among 2976 recipients, 57% were treated with T cell-depleting antibodies, 28% were treated with an IL-2 receptor antagonist, and 15% were treated without induction. There was no difference in allograft survival, death-censored graft survival, or death with function between patients treated with an IL-2 receptor antagonist and no induction therapy. In multivariable models, patients treated with T cell-depleting therapy had a similar risk of graft loss from any cause, including death (hazard ratio, 1.19; 95% confidence interval, 0.98 to 1.45), compared with patients treated with an IL-2 receptor antagonist or no induction. The findings were consistent in subgroup analyses of Black recipients, patients grouped by calculated panel reactive antibody, and donor source. The incidence of acute rejection at 1 year was low (≤5%) and did not vary between treatment groups. CONCLUSIONS: Use of induction therapy with T cell-depleting therapy or IL-2 receptor antagonists in first kidney transplant recipients who are well matched with their donor at the HLA-A, -B, -DR, -DQB1 gene loci is not associated with improved post-transplant outcomes.

Pretransplant Calculated Panel Reactive Antibody in the Absence of Donor-Specific Antibody and Kidney Allograft Survival.

BACKGROUND AND OBJECTIVES: Panel reactive antibody informs the likelihood of finding an HLA-compatible donor for transplant candidates, but has historically been associated with acute rejection and allograft survival because testing methods could not exclude the presence of concomitant donor-specific antibodies. Despite new methods to exclude donor-specific antibodies, panel reactive antibody continues to be used to determine the choice of induction and maintenance immunosuppression. The study objective was to determine the clinical relevance of panel reactive antibody in the absence of donor-specific antibodies. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Retrospective observational study of kidney allograft survival among 4058 zero HLA-A-, B-, DR-, and DQB1-mismatched transplant recipients without antibodies to donor kidney antigens encoded by these HLA gene loci. RESULTS: Among 4058 first and repeat transplant recipients, patients with calculated panel reactive antibody (cPRA) 1%-97% were not at higher risk of transplant failure, compared with patients with cPRA of 0% (death censored graft loss: hazard ratio, 1.07; 95% confidence interval, 0.82 to 1.41). Patients with cPRA ≥98% had a higher risk of graft loss from any cause including death (hazard ratio, 1.39; 95% confidence interval, 1.08 to 1.79) and death censored allograft failure (hazard ratio, 1.78; 95% confidence interval, 1.27 to 2.49). In stratified analyses, the higher risk of graft loss among patients with cPRA ≥98% was only observed among repeat, but not first, transplant recipients. In subgroup analysis, there was no association between cPRA and graft loss among living related transplant recipients. CONCLUSIONS: Calculated panel reactive antibody is poorly associated with post-transplant immune reactivity to the allograft in the absence of donor-specific antibody.

Rethinking Interpreter Functions in Mental Health Services.

Interpreters improve access to care for patients with limited English proficiency (LEP), but some studies have reported poorer cultural understanding, relationship quality, and patient satisfaction than with language-concordant care. Use of interpreter roles beyond linguistic conversion (clarifier, cultural broker, or advocate/mediator) may enhance interpreter-mediated care by improving cultural understanding and the therapeutic alliance. As reported in this column, pilot data on interpreter-mediated evaluations of 25 psychiatric outpatients with LEP support this position. The authors found that clarification of the interpreter's role and the session structure improved provider-interpreter collaboration, with two perceived benefits: improved assessment through elicitation of clinically relevant information and stronger therapeutic alliance through "emotion work." Strategies for effectively enhancing provider-interpreter collaboration are discussed.

A critical-cultural-relational approach to rupture resolution: A case illustration with a cross-racial dyad.

Ruptures are common in any therapeutic relationship and their successful resolution is associated with positive outcomes. However, therapist and client differences with regard to power, privilege, identity, and culture increase social and cultural distance, contributing to alliance ruptures and complicating the repair process. Informed by critical race theories, cultural psychological perspectives, and relational principles, we highlight how power, privilege, identity, and culture shape the development of ruptures and thus, how analyses of these dynamics should inform the process of repair. We present an expanded critical-cultural-relational approach to rupture resolution that emphasizes essential skills of critical self-awareness, wise affect, and anti-oppressive interpersonal engagement, and extends Safran and Muran's (2000) general rupture resolution model to emphasize a critical analysis of the rupture and repair processes. We illustrate our approach through a case presentation involving a rupture in a cross-racial dyad with themes of racism and classism.

Let Nature Take Its Course: Cultural Adaptation and Pilot Test of Taoist Cognitive Therapy for Chinese American Immigrants With Generalized Anxiety Disorder.

This report describes initial results from a multi-stage project to manualize and adapt an indigenous therapy, Chinese Taoist Cognitive Psychotherapy (CTCP), for dissemination in the United States context. Study aims were to (a) integrate cultural adaptation and implementation science frameworks to manualize and adapt the original intervention and (b) explore the feasibility, acceptability, and effectiveness of the modified intervention, renamed Taoist Cognitive Therapy (TCT), in a sample of Chinese immigrants with generalized anxiety disorder (GAD). Incorporating bottom-up and top-down adaptation approaches, we involved Chinese American clinician stakeholders and experts in Taoist philosophy, cognitive-behavioral therapy, and GAD to help identify cultural and contextual barriers and solutions to enhance treatment acceptability and implementation. Five treatment-seeking Chinese American immigrants (average age = 43.2 years) with a primary diagnosis of GAD completed 14-16 sessions of TCT. Two participants also had secondary diagnoses of major depressive disorder. Changes on primary measures of worry and anxiety were assessed for statistical and clinical significance using reliable change indices (RCIs; Jacobson and Truax, 1991) and comparisons to normative data. In this sample of patients with limited prior exposure to Taoism, results found evidence of feasibility and acceptability of the modified intervention, with strong endorsement of Taoist principles at termination. Statistically and clinically significant improvements in anxiety, worry, psychological inflexibility, and emotional avoidance were found only for the participants without comorbid depression. Results suggest that Taoist principles of acceptance and flexible adaptation to natural laws may be helpful to Chinese immigrants coping with anxiety. However, additional treatment modifications may be required to address the low self-efficacy and fatalism expressed among those with comorbid depression.

Discrimination as a frame-of-reference effect in overlapping friendship communities of ethnically diverse youth.

OBJECTIVES: To what extent is the frame of reference of overlapping friendship communities important for young people's feelings of discrimination and subjective well-being? That is, do youth feel better or worse to the extent that they feel less or more discrimination than their friends? METHOD: Participants (N = 898; Mage = 14.13; SDage = 3.37; 46% females; 46% Whites; 20% Indigenous; 34% other minorities) were high school students of three ethnically diverse, low socioeconomic status public schools in New South Wales, Australia. Cross-sectional data were collected to measure felt discrimination, mental health, subjective well-being, social support, and nominations of close friends. A state-of-the-art method of clustering links was used to identify overlapping friendship communities, and multiple membership multilevel models were run to examine whether community-level discrimination moderated the link between individual-level discrimination and well-being. RESULTS: When the community level discrimination was low, there was no well-being related cost or benefit of individual-level discrimination. But when the community-level discrimination was high, individuals in those communities who themselves felt low discrimination had better well-being than individuals who themselves felt high discrimination. CONCLUSIONS: We provide evidence for a frame-of-reference effect involving discrimination. Individuals' relative standing in their friendship communities with high group-level discrimination reliably predicted the individuals' well-being levels, regardless of ethnicity. The results highlight the importance of identifying overlapping friendship communities for understanding the dynamics of discrimination and well-being of ethnically diverse youth.

Inverting the power dynamic: The process of first sessions of psychotherapy with therapists of color and non-Latino white patients.

The present study is the first to apply Trawalter, Richeson, and Shelton's (2009) stress and coping framework to qualitatively examine interracial interactions in initial sessions of psychotherapy. The sample included 22 dyads: 15 therapists of color administering various treatment modalities to 15 treatment-seeking non-Latino White (NLW) patients and a comparison group of 7 intraracial (NLW-NLW) dyads. In Phase 1, videorecordings of the first session of treatment were analyzed using inductive thematic analysis (TA) to describe patient and therapist behaviors. In Phase 2, a deductive TA approach was used to interpret and cluster those dyadic behaviors according to Trawalter et al.'s (2009) framework. NLW patients paired with therapists of color made more efforts to bridge differences and more often questioned the therapist's professional qualifications compared with those matched with NLW therapists. Therapists of color made more self-disclosures than NLW therapists and maintained a more formal stance, compared with NLW therapists. The deductive TA operationalized 4 of Trawalter and colleagues' (2009) coping responses within a therapeutic framework. Findings highlight the ability of therapists' of color to engage positively with their NLW patients even in the face of challenges to their expertise and credibility. (PsycINFO Database Record

Distinct and shared three-dimensional chromosome organization patterns in lymphocytes, monoclonal gammopathy of undetermined significance and multiple myeloma.

The consistent appearance of specific chromosomal translocations in multiple myeloma has suggested that the positioning of chromosomes in the interphase nucleus might play a role in the occurrence of particular chromosomal rearrangements associated with malignant transformation. Using fluorescence in situ hybridization, we have determined the positions of selected chromosome pairs (18 and 19, 9 and 22, 4 and 14, 14 and 16, 11 and 14) in interphase nuclei of myeloma cells compared to normal lymphocytes of treatment-naïve patients. All chromosome pairs were arranged in a nonrandom pattern. Chromosomes commonly involved in myeloma-associated translocations (4 and 14, 14 and 16, 11 and 14) were found in close spatial proximity, and this is correlated with the occurrence of overlapping chromosome territories. The spatial distribution of chromosomes may increase the possibility of chromosomal translocations in multiple myeloma.

Racial/ethnic match and treatment outcomes for women with PTSD and substance use disorders receiving community-based treatment.

This study examined the relationship between racial/ethnic match and treatment outcomes for 224 women who participated in a clinical trial of group treatments for posttraumatic stress disorder (PTSD) and substance use disorders. Generalized estimating equations were used to examine the effect of client-therapist racial/ethnic match on outcomes. Results revealed racial/ethnic match was not significantly associated with session attendance. There was a significant three-way interaction between client race/ethnicity, baseline level of PTSD symptoms, and racial/ethnic match on PTSD outcomes. White clients, with severe PTSD symptoms at baseline, who attended treatment groups where they were matched with their therapist, had greater reductions in PTSD symptoms at follow-up than their counterparts who were racially/ethnically mismatched with their group therapist. Racial/ethnic match did not confer additional benefits for Black clients in terms of PTSD outcomes. Racial/ethnic match interacted with baseline substance use to differentially influence substance use outcomes at follow-up for all women. Clinical implications are discussed.
