Sialylation of immunoglobulin E is a determinant of allergic pathogenicity.

Approximately one-third of the world's population suffers from allergies1. Exposure to allergens crosslinks immunoglobulin E (IgE) antibodies that are bound to mast cells and basophils, triggering the release of inflammatory mediators, including histamine2. Although IgE is absolutely required for allergies, it is not understood why total and allergen-specific IgE concentrations do not reproducibly correlate with allergic disease3-5. It is well-established that glycosylation of IgG dictates its effector function and has disease-specific patterns. However, whether IgE glycans differ in disease states or affect biological activity is completely unknown6. Here we perform an unbiased examination of glycosylation patterns of total IgE from individuals with a peanut allergy and from non-atopic individuals without allergies. Our analysis reveals an increase in sialic acid content on total IgE from individuals with a peanut allergy compared with non-atopic individuals. Removal of sialic acid from IgE attenuates effector-cell degranulation and anaphylaxis in several functional models of allergic disease. Therapeutic interventions-including removing sialic acid from cell-bound IgE with a neuraminidase enzyme targeted towards the IgE receptor FcεRI, and administering asialylated IgE-markedly reduce anaphylaxis. Together, these results establish IgE glycosylation, and specifically sialylation, as an important regulator of allergic disease.

Differential Severe Acute Respiratory Syndrome Coronavirus 2 Antibody Profiles After Allergic Reactions to Messenger RNA Coronavirus Disease 2019 Vaccine.

Allergic symptoms after messenger RNA (mRNA) coronavirus disease 2019 (COVID-19) vaccines occur in up to 2% of recipients. Compared to nonallergic controls (n = 18), individuals with immediate allergic reactions to mRNA COVID-19 vaccines (n = 8) mounted lower immunoglobulin G1 (IgG1) to multiple antigenic targets in severe acute respiratory syndrome coronavirus 2 spike following vaccination, with significantly lower IgG1 to full-length spike (P = .04). Individuals with immediate allergic reactions to mRNA COVID-19 vaccines bound Fcγ receptors similarly to nonallergic controls. Although there was a trend toward an overall reduction in opsonophagocytic function in individuals with immediate allergic reactions compared to nonallergic controls, allergic patients produced functional antibodies exhibiting a high ratio of opsonophagocytic function to IgG1 titer.

Addressing Mistreatment by Patients in Geriatric Subspecialties: A New Framework.

Mistreatment by patients is unfortunately common in clinical medicine, including geriatric subspecialties. Despite the prevalence of this problem, there are few standardized approaches for addressing it at both interpersonal and institutional levels. The "ERASE" framework is a novel, practical approach for addressing mistreatment by patients. "ERASE" includes Expecting and preparing for mistreatment by patients, Recognizing mistreatment, Addressing mistreatment in real time, Supporting members of the healthcare team who have been mistreated, and Establishing a positive institutional culture. The framework may prove particularly helpful and applicable to providers specializing in geriatrics and can be used by administrators, educators, and all members of the healthcare team to promote safe, dignified clinical care and learning environments.

The AAGP Scholars Program: Predictors of Pursuing Geriatric Psychiatry Fellowship Training.

OBJECTIVE: The American Association for Geriatric Psychiatry (AAGP) Scholars Program was developed to recruit trainees into geriatric psychiatry fellowships and is considered a pipeline for fellowship recruitment. Nonetheless, the number of trainees entering geriatric psychiatry fellowship is declining, making it important to identify modifiable factors that may influence trainees' decisions to pursue fellowship. We analyzed survey data from Scholars Program participants to identify demographic characteristics, attitudes toward program components, and behaviors after the program that were independently associated with the decision to pursue fellowship. METHODS: Web-based surveys were distributed to all 289 former Scholars participants (2010-2018), whether or not they had completed geriatric psychiatry fellowships. We conducted a hierarchical binary logistic regression analysis to examine demographics, program components, and behaviors after the program associated with deciding to pursue geriatric psychiatry fellowship. RESULTS: Sixty-one percent of Scholars decided to pursue geriatric psychiatry fellowship. Attending more than one AAGP annual meeting (relative variance explained [RVE] = 34.2%), maintaining membership in the AAGP (RVE = 28.2%), and rating the Scholars Program as important for meeting potential collaborators (RVE = 26.6%) explained the vast majority of variance in the decision to pursue geriatric psychiatry fellowship. CONCLUSION: Nearly two-thirds of Scholars Program participants decided to pursue geriatric psychiatry fellowship, suggesting the existing program is an effective fellowship recruitment pipeline. Moreover, greater involvement in the AAGP longitudinally may positively influence Scholars to pursue fellowship. Creative approaches that encourage Scholars to develop collaborations, maintain AAGP membership, and regularly attend AAGP annual meetings may help attract more trainees into geriatric psychiatry.

Predictors for Matriculation into Geriatric Psychiatry Fellowship: Data from a 2019-2020 National Survey of U.S. Program Directors.

OBJECTIVE: With the number of geriatric psychiatry fellows declining from a peak of 106 during 2002-2003 to 48 during 2020-2021, this study aims to investigate characteristics of the geriatric psychiatry training requirement across U.S. psychiatry residency programs and to identify specific factors which may influence residents to pursue geriatric psychiatry subspecialty training. METHODS: The authors queried the American Medical Association's Fellowship and Residency Electronic Interactive Database Access system to compile a list of program directors from the Accreditation Council for Graduate Medical Education sponsored general adult psychiatry residency programs. Program directors were emailed an anonymous multiple-choice survey to ascertain specific characteristics of their program's geriatric psychiatry training experiences. This study's primary outcome was the percentage of residents entering geriatric psychiatry fellowship after completion of general psychiatry training. Linear regression analysis determined which variables may be associated with this primary outcome. RESULTS: Of 248 surveyed, 60 programs (24%) responded to the survey. Only one of the independent variables revealed a statistically significant association with the percent of residents that became geriatric psychiatry fellows: the number of geriatric psychiatrists at the residents' home institution (p=0.002). CONCLUSIONS: Consistent with previous data, the presence of geriatric psychiatry faculty members is strongly associated with the decision to pursue subspecialty training in geriatric psychiatry.

IgE Glycosylation in Health and Disease.

IgE are absolutely required for initiation of allergy reactions, which affect over 20% of the world's population. IgE are the least prevalent immunoglobulins in circulation with 12-h and 2-day half-lives in mouse and human serum, respectively, but an extended tissue half-life of 3-weeks bound to the surface of mast cells by the high affinity IgE receptor, FcεRI (Gould and Sutton 2008). Although the importance of glycosylation to IgG biology is well established, less is known regarding the contribution of IgE glycosylation to allergic inflammation. IgE has seven and nine N-linked glycosylation sites distributed across human and murine constant chains, respectively. Here we discuss studies that have analyzed IgE glycosylation and its function, and how IgE glycosylation contributions to health and disease.

The COVID-19 AAGP Online Trainee Curriculum: Development and Method of Initial Evaluation.

OBJECTIVE: One effect of the COVID-19 pandemic is the disruption of in-person clinical experiences within geriatric psychiatry residency education. Online resources for trainees are needed to fill resultant gaps. METHODS: The American Association of Geriatric Psychiatry (AAGP) Teaching and Training Committee leadership collaborated with geriatric psychiatry experts to develop a web-based geriatric psychiatry curriculum for psychiatry residents and other learners. In addition, we planned to obtain initial self-report outcomes of the curricular modules. RESULTS: The COVID-19 AAGP Online Trainee Curriculum (aagponline.org/covidcurriculum) consists of approximately 30 video-recorded lectures provided by AAGP member experts. A demographic survey and pre-/postsurvey attached to each module allow us to obtain learner characteristics and feedback on each module. CONCLUSIONS: The Curriculum has the potential to supplement psychiatry residency education during the pandemic and potentially raise the profile of AAGP, with the goal of inspiring interest within geriatric psychiatry. Results of the initial self-report evaluation should be available in 1 year.

Combating Heightened Social Isolation of Nursing Home Elders: The Telephone Outreach in the COVID-19 Outbreak Program.

OBJECTIVE: Social isolation and loneliness-common concerns in older adults-are exacerbated by the COVID-19 pandemic. To address social isolation in nursing home residents, the Yale School of Medicine Geriatrics Student Interest Group initiated a Telephone Outreach in the COVID-19 Outbreak (TOCO) Program that implements weekly phone calls with student volunteers. METHODS: Local nursing homes were contacted; recreation directors identified appropriate and interested elderly residents. Student volunteers were paired with elderly residents and provided phone call instructions. RESULTS: Three nursing homes opted to participate in the program. Thirty elderly residents were paired with student volunteers. Initial reports from recreation directors and student volunteers were positive: elderly residents look forward to weekly phone calls and express gratitude for social connectedness. CONCLUSIONS: The TOCO program achieved initial success and promotes the social wellbeing of nursing home residents. We hope to continue this program beyond the COVID-19 pandemic in order to address this persistent need in a notably vulnerable patient population.

The American Association for Geriatric Psychiatry's Trainee Programs: Participant Characteristics and Perceived Benefits.

OBJECTIVE: The number of physicians trained in geriatric psychiatry is dwindling. The American Association for Geriatric Psychiatry (AAGP) developed novel educational programs designed to foster interest in the field. The objective of this study was to compare participant characteristics and perceived benefits of two AAGP educational programs for trainees: Stepping Stones (1997-2007) and the Scholars Program (2010-2016). METHODS: Web-based surveys were distributed to former participants of the Stepping Stones and Scholars Programs. Characteristics of participants in the two programs were compared using χ2, t tests, or Mann-Whitney U tests, as appropriate. The five-point Likert scale responses for each perceived benefit were compared using t tests, when normally distributed, or Mann-Whitney U tests as appropriate. RESULTS: Of the 476 Stepping Stones participants, 132 (27.8%) responded to the survey, while 64 (29.0%) of the 221 Scholars Program participants responded to the survey. Participant characteristics differed only in age. Compared to Stepping Stones participants, Scholars Program participants endorsed greater advancement of their scholarly work, more support and recognition from their home institution, and increased networking opportunities. CONCLUSION: Innovative approaches to addressing the geriatric psychiatry workforce shortage are critical. The member-funded AAGP Scholars Program offers several advantages over its predecessor Stepping Stones. Highlighted by the addition of medical student participants, a carefully matched mentoring program, and a required scholarly project, the Scholars Program is poised to enhance recruitment into geriatric psychiatry subspecialty training, although its impact on recruitment should be investigated directly in future research.

A Call to Restructure Psychiatry General and Subspecialty Training.

Dire shortages of psychiatrists with special expertise in geriatrics, substance abuse, forensics, and psychosomatics create barriers to care for populations with complex mental disorders and pose a significant public health concern. To address these disparities in access to care, we propose streamlining graduate medical education to increase efficiency and enhance cost-effectiveness while simultaneously increasing the number of psychiatric subspecialists in these key areas. We propose that trainees interested in subspecialties complete their general training in 3 years, while meeting ACGME required milestones, and then utilize their 4th year to complete subspecialty fellowship training. Eligible trainees would then qualify for psychiatry subspecialty certification and general psychiatry ABPN certification at the end of 4 years.

Validation of anaphylaxis in the Food and Drug Administration's Mini-Sentinel.

PURPOSE: We aim to develop and validate the positive predictive value (PPV) of an algorithm to identify anaphylaxis using health plan administrative and claims data. Previously published PPVs for anaphylaxis using International Classification of Diseases, ninth revision, Clinical Modification (ICD-9-CM) codes range from 52% to 57%. METHODS: We conducted a retrospective study using administrative and claims data from eight health plans. Using diagnosis and procedure codes, we developed an algorithm to identify potential cases of anaphylaxis from the Mini-Sentinel Distributed Database between January 2009 and December 2010. A random sample of medical charts (n = 150) was identified for chart abstraction. Two physician adjudicators reviewed each potential case. Using physician adjudicator judgments on whether the case met diagnostic criteria for anaphylaxis, we calculated a PPV for the algorithm. RESULTS: Of the 122 patients for whom complete charts were received, 77 were judged by physician adjudicators to have anaphylaxis. The PPV for the algorithm was 63.1% (95%CI: 53.9-71.7%), using the clinical criteria by Sampson as the gold standard. The PPV was highest for inpatient encounters with ICD-9-CM codes of 995.0 or 999.4. By combining only the top performing ICD-9-CM codes, we identified an algorithm with a PPV of 75.0%, but only 66% of cases of anaphylaxis were identified using this modified algorithm. CONCLUSIONS: The PPV for the ICD-9-CM-based algorithm for anaphylaxis was slightly higher than PPV estimates reported in prior studies, but remained low. We were able to identify an algorithm that optimized the PPV but demonstrated lower sensitivity for anaphylactic events.

Food Allergies and Anaphylaxis in the Community: The School Nurse's Role.

Food allergy prevalence in the United States has been increasing among school-aged children. Many community-based pediatric caregivers (e.g., camp staff, sports coaches) are not trained to prevent, recognize, or manage allergic reactions due to a lack of available training and standard policies on this topic. Epinephrine is the first-line of treatment for severe allergic reactions and delayed administration of this medication can result in poor health outcomes and death. School nurses may use their knowledge and expertise to educate community-based pediatric caregivers on allergy topics. Professional practice projects can be utilized by school nurses to help improve allergy and anaphylaxis confidence and knowledge among community-based pediatric caregivers. By educating community members on anaphylaxis management, it can improve health outcomes for children of the school community and result in saved lives.

Insomnia and Other Sleep Disorders in Older Adults.

Sleep disruption is common in older adults and is associated with many poor health outcomes. It is vital for providers to understand insomnia and other sleep disorders in this population. This article outlines age-related changes in sleep, and medical, psychiatric, environmental, and psychosocial factors that may impact sleep. It addresses the evaluation of sleep symptoms and diagnosis of sleep disorders. It aims to examine the evidence for non-pharmacological and pharmacologic treatment options for insomnia while weighing factors particularly germane to the aging adult..

Geriatric Psychiatry Across the Spectrum: Medical Student, Resident, and Fellow Education.

The older adult population in the United States is poised to reach 83.7 million by 2050, and up to 20% will suffer from cognitive and mental illnesses. We do not have the workforce available to meet this need; therefore, general psychiatrists will care for many older psychiatric patients. Enhancing learning opportunities during general medical education and residency could improve the knowledge of general psychiatrists and encourage recruitment into geriatric psychiatry. This article outlines geriatric psychiatry education in medical school, residency, and geriatric psychiatry fellowship with suggestions for recruitment into the field, along with recommendations for enhanced learning for general psychiatrists.

Duodenal helminth infection alters barrier function of the colonic epithelium via adaptive immune activation.

Chronic infection with intestinal helminth parasites is a major public health problem, particularly in the developing world, and can have significant effects on host physiology and the immune response to other enteric infections and antigens. The mechanisms underlying these effects are not well understood. In the current study, we investigated the impact of infection with the murine nematode parasite Heligmosomoides polygyrus, which resides in the duodenum, on epithelial barrier function in the colon. We found that H. polygyrus infection produced a significant increase in colonic epithelial permeability, as evidenced by detection of elevated serum levels of the tracer horseradish peroxidase following rectal administration. This loss of normal barrier function was associated with clear ultrastructural changes in the tight junctions of colonic epithelial cells and an alteration in the expression and distribution of the junctional protein E-cadherin. These parasite-induced abnormalities were not observed in SCID mice but did occur in SCID mice that were adoptively transferred with wild-type T cells, indicating a requirement for adaptive immunity. Furthermore, the helminth-induced increase in gut permeability was not seen in STAT6 knockout (KO) mice. Taken together, the results demonstrate that one of the mechanisms by which helminths exert their effects involves the lymphocyte- and STAT6-dependent breakdown of the intestinal epithelial barrier. This increase in epithelial permeability may facilitate the movement of lumenal contents across the mucosa, thus helping to explain how helminth infection can alter the immune response to enteric antigens.

Prevalence and clinical characteristics of body dysmorphic disorder in an adult inpatient setting.

OBJECTIVE: Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, is an often-severe, understudied disorder. We determined BDD's prevalence and clinical features on a general adult psychiatric inpatient unit. To our knowledge, only one previous prevalence study has been done in this setting. METHOD: One hundred patients completed 3 self-report measures: the Body Dysmorphic Disorder Questionnaire (BDD-Q), Beck Anxiety Inventory (BAI) and Center for Epidemiologic Studies Depression Scale (CES-D). Those who screened positive for BDD were interviewed to confirm DSM-IV BDD and its clinical features. Charts were reviewed for demographic and clinical information. RESULTS: BDD was diagnosed in 16.0% (95% CI=8.7-23.3%) (n=16) of patients. A high proportion of those with BDD reported that BDD symptoms contributed to suicidality. Patients revealed BDD symptoms to a mean of only 15.1%+/-33.7% lifetime mental health clinicians; only one (6.3%) reported symptoms to his current inpatient psychiatrist. Most did not disclose their symptoms due to embarrassment. Those with BDD were younger (P=.008) and had higher CES-D scores (P=.008). The two groups did not significantly differ on BAI score, demographic characteristics or discharge diagnoses. CONCLUSIONS: BDD is relatively common but underdiagnosed in psychiatric inpatients and is associated with more severe depressive symptoms.

Prefrontal cortex and decision making in a mixed-strategy game.

In a multi-agent environment, where the outcomes of one's actions change dynamically because they are related to the behavior of other beings, it becomes difficult to make an optimal decision about how to act. Although game theory provides normative solutions for decision making in groups, how such decision-making strategies are altered by experience is poorly understood. These adaptive processes might resemble reinforcement learning algorithms, which provide a general framework for finding optimal strategies in a dynamic environment. Here we investigated the role of prefrontal cortex (PFC) in dynamic decision making in monkeys. As in reinforcement learning, the animal's choice during a competitive game was biased by its choice and reward history, as well as by the strategies of its opponent. Furthermore, neurons in the dorsolateral prefrontal cortex (DLPFC) encoded the animal's past decisions and payoffs, as well as the conjunction between the two, providing signals necessary to update the estimates of expected reward. Thus, PFC might have a key role in optimizing decision-making strategies.
