Shedding of infectious SARS-CoV-2 despite vaccination.

The SARS-CoV-2 Delta Variant of Concern is highly transmissible and contains mutations that confer partial immune escape. The emergence of Delta in North America caused the first surge in COVID-19 cases after SARS-CoV-2 vaccines became widely available. To determine whether individuals infected despite vaccination might be capable of transmitting SARS-CoV-2, we compared RT-PCR cycle threshold (Ct) data from 20,431 test-positive anterior nasal swab specimens from fully vaccinated (n = 9,347) or unvaccinated (n = 11,084) individuals tested at a single commercial laboratory during the interval 28 June- 1 December 2021 when Delta variants were predominant. We observed no significant effect of vaccine status alone on Ct value, nor when controlling for vaccine product or sex. Testing a subset of low-Ct (<25) samples, we detected infectious virus at similar rates, and at similar titers, in specimens from vaccinated and unvaccinated individuals. These data indicate that vaccinated individuals infected with Delta variants are capable of shedding infectious SARS-CoV-2 and could play a role in spreading COVID-19.

Sensitivity of rapid antigen tests for Omicron subvariants of SARS-CoV-2.

Diagnosis by rapid antigen tests (RATs) is useful for early initiation of antiviral treatment. Because RATs are easy to use, they can be adapted for self-testing. Several kinds of RATs approved for such use by the Japanese regulatory authority are available from drug stores and websites. Most RATs for COVID-19 are based on antibody detection of the SARS-CoV-2 N protein. Since Omicron and its subvariants have accumulated several amino acid substitutions in the N protein, such amino acid changes might affect the sensitivity of RATs. Here, we investigated the sensitivity of seven RATs available in Japan, six of which are approved for public use and one of which is approved for clinical use, for the detection of BA.5, BA.2.75, BF.7, XBB.1, and BQ.1.1, as well as the delta variant (B.1.627.2). All tested RATs detected the delta variant with a detection level between 7500 and 75 000 pfu per test, and all tested RATs showed similar sensitivity to the Omicron variant and its subvariants (BA.5, BA.2.75, BF.7, XBB.1, and BQ.1.1). Human saliva did not reduce the sensitivity of the RATs tested. Espline SARS-CoV-2 N showed the highest sensitivity followed by Inspecter KOWA SARS-CoV-2 and V Trust SARS-CoV-2 Ag. Since the RATs failed to detect low levels of infectious virus, individuals whose specimens contained less infectious virus than the detection limit would be considered negative. Therefore, it is important to note that RATs may miss individuals shedding low levels of infectious virus.

High-Throughput Identification of MHC Class I Binding Peptides Using an Ultradense Peptide Array.

Rational vaccine development and evaluation requires identifying and measuring the magnitude of epitope-specific CD8 T cell responses. However, conventional CD8 T cell epitope discovery methods are labor intensive and do not scale well. In this study, we accelerate this process by using an ultradense peptide array as a high-throughput tool for screening peptides to identify putative novel epitopes. In a single experiment, we directly assess the binding of four common Indian rhesus macaque MHC class I molecules (Mamu-A1*001, -A1*002, -B*008, and -B*017) to ∼61,000 8-mer, 9-mer, and 10-mer peptides derived from the full proteomes of 82 SIV and simian HIV isolates. Many epitope-specific CD8 T cell responses restricted by these four MHC molecules have already been identified in SIVmac239, providing an ideal dataset for validating the array; up to 64% of these known epitopes are found in the top 192 SIVmac239 peptides with the most intense MHC binding signals in our experiment. To assess whether the peptide array identified putative novel CD8 T cell epitopes, we validated the method by IFN-γ ELISPOT assay and found three novel peptides that induced CD8 T cell responses in at least two Mamu-A1*001-positive animals; two of these were validated by ex vivo tetramer staining. This high-throughput identification of peptides that bind class I MHC will enable more efficient CD8 T cell response profiling for vaccine development, particularly for pathogens with complex proteomes for which few epitope-specific responses have been defined.

Aggression Prevention Training for Individuals With Dementia and Their Caregivers: A Randomized Controlled Trial.

OBJECTIVE: International appeals call for interventions to prevent aggression and other behavioral problems in individuals with dementia (IWD). Aggression Prevention Training (APT), based on intervening in three contributors to development of aggression (IWD pain, IWD depression, and caregiver-IWD relationship problems) aims to reduce incidence of aggression in IWD over 1 year. DESIGN: Randomized, controlled trial. SETTING: Three clinics that assess, diagnose, and treat dementia. PARTICIPANTS: Two hundred twenty-eight caregiver-IWD dyads who screened positive for IWD pain, IWD depression, or caregiver-IWD relationship problems randomized to APT or Enhanced Usual Primary Care (EU-PC). INTERVENTION: APT, a skills-based intervention delivered over 3 months to address pain/depression/caregiver-IWD relationship issues. EU-PC included printed material on dementia and community resources; and eight brief, weekly support calls. MEASUREMENTS: The primary outcome was incidence of aggression over 1 year, determined by the Cohen Mansfield Agitation Inventory-Aggression Subscale. Secondary outcomes included pain, depression, caregiver-IWD relationship, caregiver burden, positive caregiving, behavior problems, and anxiety. RESULTS: Aggression incidence and secondary outcomes did not differ between groups. However, in those screening positive for IWD depression or caregiver-IWD relationship problems, those receiving EU-PC had significant increases in depression and significant decreases in quality of the caregiver-IWD relationship, whereas those receiving APT showed no changes in these outcomes over time. CONCLUSION: The cost to patients, family, and society of behavioral problems in IWD, along with modest efficacy of most pharmacologic and nonpharmacologic interventions, calls for more study of novel preventive approaches.

Bone Accrual in Children and Adolescent Nonelite Swimmers: A 2-Year Longitudinal Study.

OBJECTIVE: To examine differences in bone mass between children and adolescents swimming competitively at nonelite levels (locally and regionally) and nonathletes and to assess changes in bone mass in these 2 groups over 24 months after taking into consideration several known confounders of bone mass. DESIGN: Observational prospective study. PARTICIPANTS: White nonelite swimmers (n = 128) and nonathletes (n = 106) 8 to 18 years of age from Memphis, Tennessee, USA. MAIN OUTCOME MEASURES: Participants underwent dual-energy x-ray absorptiometry to assess total body and hip bone mineral content (BMC) at baseline and 12 and 24 months later. RESULTS: At baseline, swimmers had 4.2% and 6.1% higher adjusted BMC for the total body and hip, respectively, compared with nonathletes (P values < 0.027). Averaging across assessment points, swimmers had 73.5 and 2.2 g higher BMC for the total body and hip, respectively, than nonathletes. Although there was a significant annual increase in total body and hip BMC in both groups (33.5 and 0.7 g, respectively), there was no difference in annualized bone accrual between swimmers and nonathletes for either total body BMC (swim by time effect; P = 0.213) or hip BMC (P = 0.265). CONCLUSIONS: Competitive swimming at nonelite levels during childhood and adolescence does not seem to compromise bone accrual.

Community-Based Outreach and Treatment for Underserved Older Adults With Clinically Significant Worry: A Randomized Controlled Trial.

OBJECTIVE: To determine whether Calmer Life (CL) improved worry, generalized anxiety disorder-related (GAD-related) symptoms, anxiety, depression, sleep, trauma-related symptoms, functional status, and quality of life better than Enhanced Community Care with Resource Counseling (ECC-RC) at 6 months and 9 months. METHODS: A randomized, controlled, comparative-effectiveness study involving underserved, low-income, mostly minority neighborhoods in Houston, Texas, looked at individuals ≥50 with significant worry and interest in psychosocial treatment. Interventions were CL, cognitive behavioral therapy with resource counseling, facilitation of communication with primary care providers about worry/anxiety, integration of religion/spirituality, person-centered skill content and delivery and nontraditional community providers, ECC-RC, and enhanced standard community-based information/ resource counseling addressing basic unmet and mental health needs. Primary outcomes were worry and GAD-related symptom severity. Secondary outcomes were anxiety, depression, sleep difficulties, trauma-related symptoms, functional status, quality of life, service use and satisfaction. RESULTS: Similar, moderate improvements followed CL and ECC-RC on worry, GAD-related symptoms, anxiety, depression, sleep, trauma-related symptoms, and mental health quality of life at 6 and 9 months, but with symptoms at both times and higher satisfaction with CL at both. Fewer ECC-RC participants reported a hospital admission in the prior 3 months than those in CL at 6 and 9 months; at 9 months, fewer reported a visit with a provider in the previous 3 months. CONCLUSION: Both interventions showed similar improvements at 6 and 9 months, but symptoms remained that might require care. Either intervention or a combination may be useful for low-income older adults with identified worry/anxiety.

Vaccine-induced CD8+ T cells control AIDS virus replication.

Developing a vaccine for human immunodeficiency virus (HIV) may be aided by a complete understanding of those rare cases in which some HIV-infected individuals control replication of the virus. Most of these elite controllers express the histocompatibility alleles HLA-B*57 or HLA-B*27 (ref. 3). These alleles remain by far the most robust associations with low concentrations of plasma virus, yet the mechanism of control in these individuals is not entirely clear. Here we vaccinate Indian rhesus macaques that express Mamu-B*08, an animal model for HLA-B*27-mediated elite control, with three Mamu-B*08-restricted CD8(+) T-cell epitopes, and demonstrate that these vaccinated animals control replication of the highly pathogenic clonal simian immunodeficiency virus (SIV) mac239 virus. High frequencies of CD8(+) T cells against these Vif and Nef epitopes in the blood, lymph nodes and colon were associated with viral control. Moreover, the frequency of the CD8(+) T-cell response against the Nef RL10 epitope (Nef amino acids 137-146) correlated significantly with reduced acute phase viraemia. Finally, two of the eight vaccinees lost control of viral replication in the chronic phase, concomitant with escape in all three targeted epitopes, further implicating these three CD8(+) T-cell responses in the control of viral replication. Our findings indicate that narrowly targeted vaccine-induced virus-specific CD8(+) T-cell responses can control replication of the AIDS virus.

Suppression of a Natural Killer Cell Response by Simian Immunodeficiency Virus Peptides.

Natural killer (NK) cell responses in primates are regulated in part through interactions between two highly polymorphic molecules, the killer-cell immunoglobulin-like receptors (KIRs) on NK cells and their major histocompatibility complex (MHC) class I ligands on target cells. We previously reported that the binding of a common MHC class I molecule in the rhesus macaque, Mamu-A1*002, to the inhibitory receptor Mamu-KIR3DL05 is stabilized by certain simian immunodeficiency virus (SIV) peptides, but not by others. Here we investigated the functional implications of these interactions by testing SIV peptides bound by Mamu-A1*002 for the ability to modulate Mamu-KIR3DL05+ NK cell responses. Twenty-eight of 75 SIV peptides bound by Mamu-A1*002 suppressed the cytolytic activity of primary Mamu-KIR3DL05+ NK cells, including three immunodominant CD8+ T cell epitopes previously shown to stabilize Mamu-A1*002 tetramer binding to Mamu-KIR3DL05. Substitutions at C-terminal positions changed inhibitory peptides into disinhibitory peptides, and vice versa, without altering binding to Mamu-A1*002. The functional effects of these peptide variants on NK cell responses also corresponded to their effects on Mamu-A1*002 tetramer binding to Mamu-KIR3DL05. In assays with mixtures of inhibitory and disinhibitory peptides, low concentrations of inhibitory peptides dominated to suppress NK cell responses. Consistent with the inhibition of Mamu-KIR3DL05+ NK cells by viral epitopes presented by Mamu-A1*002, SIV replication was significantly higher in Mamu-A1*002+ CD4+ lymphocytes co-cultured with Mamu-KIR3DL05+ NK cells than with Mamu-KIR3DL05- NK cells. These results demonstrate that viral peptides can differentially affect NK cell responses by modulating MHC class I interactions with inhibitory KIRs, and provide a mechanism by which immunodeficiency viruses may evade NK cell responses.

Teaching Caregivers of Persons with Dementia to Address Pain.

OBJECTIVES: To compare the efficacy of Preventing Aggression in Veterans with Dementia (PAVeD) with that of usual care in decreasing incidence of aggression (primary outcome) and pain and improving depression, pleasant events, caregiver burden, and patient-caregiver relationship quality (secondary outcomes). DESIGN: Randomized controlled trial with assessments at baseline and 3, 6, 9, and 12 months SETTING: Houston, TX. PARTICIPANTS: A total of 203 community-dwelling veterans with pain and dementia and their caregivers. INTERVENTION: PAVeD, 6 to 8 weekly sessions of 45-minute home visits with masters-level clinicians providing instruction to caregivers on recognizing pain, enhancing communication, and making daily activities pleasant and enjoyable, and at least two elective sessions. MEASUREMENTS: Cohen-Mansfield Agitation Inventory (primary outcome), Philadelphia Geriatric Pain Intensity Scale, Geriatric Depression Scale, Pleasant Events Schedule-AD, Burden Interview, Mutuality Scale (secondary outcomes), Client Satisfaction Questionnaire. RESULTS: There were no significant differences in aggression incidence between intervention and control groups, although the PAVeD group had significantly better mutuality than controls. CONCLUSIONS: PAVeD may need to address a broader range and more in-depth coverage of aggression risk factors with person-centered tailoring to target certain types of distress. Interventions to prevent aggression may also need to address medical providers in addition to caregivers.

Pain Among Community-Dwelling Older Adults with Dementia: Factors Associated with Undertreatment.

OBJECTIVE: To identify factors associated with no analgesic treatment in community-dwelling older adults with mild-to-moderate dementia and moderate-to-severe pain. DESIGN: Secondary analysis of a randomized controlled trial. SETTING: Michael E. DeBakey Veterans Affairs Medical Center. SUBJECTS: Two hundred and two older adults (mean age = 79.27 years). METHODS: Guided by the Behavioral Model of Health Service Utilization, participants completed questionnaires regarding predisposing (age, gender, race, educational level, care partner relationship), enabling (income), and need (pain interference, depressive symptoms, cognitive functioning) characteristics. RESULTS: Hierarchical logistic regression analyses revealed that participants with greater income (odds ratio [OR] = 0.79, 95% confidence interval [CI] = 0.63-0.99) and greater pain interference (OR = 0.79, 95% CI = 0.63-0.99) were less likely to have no analgesic treatment. We also examined whether other factors such as depressive symptoms influenced the relationship between pain interference and pain treatment. Those with less pain interference were more likely to have no analgesic treatment (OR = 1.04, 95% CI = 1.01-1.08), but only if they had lower levels of depressive symptoms (b = -0.52, P = 0.005). CONCLUSION: The initiation of analgesic trials is complicated for individuals with dementia and comorbid pain and depressive symptomology. Future research should focus on identifying the most effective assessment and treatment procedures to best direct clinical care for this population.

Negative Consequences of Family Caregiving for Veterans With PTSD and Dementia.

Recent research shows veterans with posttraumatic stress disorder (PTSD) are twice as likely as other veterans to develop dementia. However, no studies to date have examined the impact of co-existing PTSD and dementia on family caregivers, who provide the majority of care to these veterans. Using the Stress Process Model, the current investigation explored the similarities and differences in psychosocial, health, and service use outcomes among caregivers assisting veterans with PTSD and dementia compared with caregivers assisting veterans with dementia only. Caregivers of veterans with PTSD and dementia indicated that their relative exhibited more difficult behavior symptoms and used more community services. These caregivers also reported more difficulties understanding veterans' memory problems and more physical strain. Together, results suggested caregivers of veterans with both PTSD and dementia were at greater risk of negative caregiving consequences. Implications and suggestions for future research are discussed.

Expanding the geriatric mental health workforce through utilization of non-licensed providers.

OBJECTIVES: We evaluate policy and practice strategies for bolstering the geriatric mental healthcare workforce and describe costs and considerations of implementing one approach. METHOD: Narrative overview of the literature and policy retrieved from searches of databases, hand searches, and authoritative texts. We identified three proposed strategies to increase the geriatric mental healthcare workforce: (1) production of more geriatric mental health providers; (2) team-based care; and (3) non-licensed providers. We evaluate each in terms of challenges and potential and provide estimates of costs, policy, and practice considerations for training, employing, and supervising non-licensed mental health providers. RESULTS: Use of non-licensed providers is key to reforms needed to allow a more older adults to access necessary mental healthcare. Licensed and non-licensed providers have achieved similar improvements for generalized anxiety disorder among patients, although non-licensed providers did so at a lower cost. CONCLUSION: Supervised non-licensed providers can extend the reach of licensed providers for specific mental health conditions, resulting in lower costs and increased number of patients treated. Although several barriers to implementation exist, policy and infrastructure changes that may support this type of care delivery model are emerging from reforms in financing and associated delivery initiatives created by the Affordable Care Act.

Vida Calma: CBT for Anxiety with a Spanish-Speaking Hispanic Adult.

BACKGROUND: Hispanic adults aged 55 years and older are the fastest growing ethnic minority group in the United States facing significant mental health disparities. Barriers in accessing care have been attributed to low income, poor education, language barriers, and stigma. Cultural adaptations to existing evidence-based treatments have been encouraged to improve access. However, little is known about mental health treatments translated from English to Spanish targeting anxiety among this Hispanic age group. Objctive: This case study offers an example of how an established, manualized, cognitive-behavioral treatment for adults 55 years and older with generalized anxiety disorder (known as "Calmer Life") was translated to Spanish ("Vida Calma") and delivered to a monolingual, Hispanic 55-year-old woman. RESULTS: Pre- and post-treatment measures showed improvements in symptoms of anxiety, depression, and life satisfaction. CONCLUSION: Findings suggest Vida Calma is a feasible treatment to use with a 55-year-old Spanish-speaking adult woman. CLINICAL IMPLICATIONS: Vida Calma, a Spanish language version of Calmer Life, was acceptable and feasible to deliver with a 55-year-old participant with GAD. Treatment outcomes demonstrate that Vida Calma improved the participant's anxiety, depression, and life satisfaction.

Telephone-Delivered Cognitive-Behavioral Therapy for Older, Rural Veterans with Depression and Anxiety in Home-Based Primary Care.

OBJECTIVES: Rural, homebound older adults are at increased risk for anxiety and depression and have limited access to mental health services. These individuals face many barriers to receiving evidence-based mental health treatment and would benefit from interventions that increase access to and efficiency of care. The aim of this study was to evaluate use of a telephone-delivered, modular, cognitive behavioral therapy (CBT) intervention for both late-life depression and anxiety delivered to rural, homebound Veterans. METHODS: Three cases are presented to illustrate the flexible adaptation of the intervention for use among older Veterans enrolled in home-based primary care, with varying symptom presentations and functional limitations. The Veterans received 7 to 9 sessions of the CBT intervention, with ordering of skill modules based on symptom presentation and determined collaboratively between patient and therapist. RESULTS: The three Veterans showed improvement in depression and/or anxiety symptoms following treatment and provided positive feedback regarding their experiences in this program. CONCLUSIONS: These results suggest that telephone-delivered CBT is acceptable to older adults and can be tailored to individual patient needs. CLINICAL IMPLICATIONS: Clinicians should consider telephone-delivered CBT as an alternate mode of therapy to increase access to mental health care for rural, homebound individuals with depression and anxiety.

Predictors of Outcomes for Older Adults Participating in Calmer Life, a Culturally Tailored Intervention for Anxiety.

OBJECTIVE: Determine predictors of reduced worry and anxiety for older adults participating in the pilot phase of Calmer Life, a modular, personalized cognitive-behavioral treatment for worry. METHODS: Underserved adults (N = 54) over age 50 participated. Therapists were either experts (Ph.D. or Master's) or nonexpert providers (case managers, community health workers, and bachelor's level). Participants completed the Penn State Worry Questionnaire-Abbreviated (PSWQ-A) and the Geriatric Anxiety Inventory-Short Form (GAI-SF) before treatment and at 3 months. RESULTS: Demographic and clinical variables were individually entered into separate regression equations, controlling for pretreatment scores, to determine their associations with post-treatment 1) PSWQ-A and 2) GAI-SF scores. Only younger age and African American race were significant (p < .05) univariate predictors of higher post-treatment PSWQ-A scores. African American race was also a significant predictor of higher post-treatment GAI-SF scores. CONCLUSIONS: African American participants had higher post-treatment PSWQ-A and GAI-SF scores than White and Hispanic participants. Younger age was also associated with more severe PSWQ-A post-treatment scores. CLINICAL IMPLICATIONS: Younger participants may experience additional stressors (e.g., caregiving, working) compared with older participants. Smaller decreases in anxiety in African Americans point to the need for continued focus and additional modification of interventions.

Calmer Life: A Culturally Tailored Intervention for Anxiety in Underserved Older Adults.

OBJECTIVES: To evaluate the feasibility of the Calmer Life and Enhanced Community Care interventions delivered by community and expert providers and test their preliminary effectiveness on worry, generalized anxiety disorder (GAD) severity, anxiety, depression, sleep, health-related quality of life, and satisfaction. DESIGN: Small randomized trial, with measurements at baseline and 3 months. SETTING: Underserved, low-income, mostly minority communities in Houston, TX. PARTICIPANTS: Forty underserved adults 50 years and older, with significant worry and principal or coprincipal GAD or anxiety disorder not otherwise specified. INTERVENTION: Combination of person-centered, flexible skills training to reduce worry; resource counseling to target unmet basic needs; and facilitation of communication with primary care providers developed through a community-academic partnership with social service and faith-based organizations. Religion/spirituality may be incorporated. PRIMARY OUTCOMES: worry (Penn State Worry Questionnaire-Abbreviated), GAD severity (GAD-7), anxiety (Geriatric Anxiety Inventory-Short Form). SECONDARY OUTCOMES: depression (Patient Health Questionnaire-8 and Geriatric Depression Scale-Short Form), sleep (Insomnia Severity Index), health-related quality of life (12-item Medical Outcomes Study Short Form), satisfaction (Client Satisfaction Questionnaire and exit interviews). RESULTS: Provider training was valid; mean ratings for community providers were well above average, with none less than adequate. Reach was excellent. Participants receiving the Calmer Life intervention had greater improvement in GAD severity and depression than those receiving Enhanced Community Care. Satisfaction with both treatments was equivalent. CONCLUSIONS: A larger comparative-effectiveness trial needs to examine outcomes following the Calmer Life intervention relative to standard community-based care and to evaluate more fully issues of implementation potential.

Compartmentalization of simian immunodeficiency virus replication within secondary lymphoid tissues of rhesus macaques is linked to disease stage and inversely related to localization of virus-specific CTL.

We previously demonstrated that HIV replication is concentrated in lymph node B cell follicles during chronic infection and that HIV-specific CTL fail to accumulate in large numbers at those sites. It is unknown whether these observations can be generalized to other secondary lymphoid tissues or whether virus compartmentalization occurs in the absence of CTL. We evaluated these questions in SIVmac239-infected rhesus macaques by quantifying SIV RNA(+) cells and SIV-specific CTL in situ in spleen, lymph nodes, and intestinal tissues obtained at several stages of infection. During chronic asymptomatic infection prior to simian AIDS, SIV-producing cells were more concentrated in follicular (F) compared with extrafollicular (EF) regions of secondary lymphoid tissues. At day 14 of infection, when CTL have minimal impact on virus replication, there was no compartmentalization of SIV-producing cells. Virus compartmentalization was diminished in animals with simian AIDS, which often have low-frequency CTL responses. SIV-specific CTL were consistently more concentrated within EF regions of lymph node and spleen in chronically infected animals regardless of epitope specificity. Frequencies of SIV-specific CTL within F and EF compartments predicted SIV RNA(+) cells within these compartments in a mixed model. Few SIV-specific CTL expressed the F homing molecule CXCR5 in the absence of the EF retention molecule CCR7, possibly accounting for the paucity of F CTL. These findings bolster the hypothesis that B cell follicles are immune privileged sites and suggest that strategies to augment CTL in B cell follicles could lead to improved viral control and possibly a functional cure for HIV infection.

Cognitive behavior therapy for late-life generalized anxiety disorder delivered by lay and expert providers has lasting benefits.

OBJECTIVE: Peaceful Living, a cognitive-behavioral treatment (CBT) for late-life generalized anxiety disorder (GAD), produced positive outcomes in GAD severity, anxiety, depression, insomnia, and mental health quality of life relative to usual care with treatment delivered by either bachelor-level lay providers (BLPs) or PhD-level expert providers (PLPs). We examined long-term maintenance of gains during 12 months following CBT for patients in this trial who received the intervention delivered by BLPs and PLPs and completed post-treatment assessments. METHODS: Participants were 112 older adults (mean age, 66.83 years) with GAD recruited from primary care who received CBT from BLPs (n = 52) or PLPs (n = 60) and completed post-treatment assessments. Assessments were given at post-treatment and at 6- and 12-month follow-up. Primary outcomes assessed long-term maintenance of gains in worry (Generalized Anxiety Disorder Severity Scale) and anxiety (State-Trait Anxiety Inventory, Structured Interview Guide for the Hamilton Anxiety Scale). Secondary outcomes assessed depression (Patient Health Questionnaire), mental health quality of life (Medical Outcomes Study Short Form - mental wellness scale), and sleep (Insomnia Severity Index). RESULTS: At 6- and 12-month follow-ups, post-treatment reductions in GAD severity, anxiety, depression, and improvements in mental health quality of life and sleep were maintained for patients in both groups. No differences were found, based on provider group. CONCLUSION: Treatment of late-life anxiety delivered by nonexpert lay providers working under supervision of licensed providers has lasting benefits. These findings support the potential of new models of care for older adults that may expand reach of mental health services. Copyright © 2016 John Wiley & Sons, Ltd.
