Racial disparities in the diagnosis of disruptive behavior disorders: a U.S. national inpatient sample analysis.

Disruptive behavior disorders (DBDs) are comprised of conduct disorder and oppositional defiant disorder. Limited literature exists on the demographics of patients diagnosed with these conditions. Despite the clinical overlap of DBDs and attention-deficit hyperactivity disorder (ADHD), there is a stark divergence in the treatment and societal accommodation for these two diagnoses, amplifying the importance of this diagnostic challenge. Thus, potential diagnostic differences must be urgently and rigorously explored. Small, regional studies have reported potential "racial" disparities in the diagnosis of DBDs, especially when compared to the diagnosis of ADHD. Our study uses the National Inpatient Sample (NIS) database to provide the largest, most comprehensive investigation of "racial" disparities in the diagnosis of DBDs. Discharge data from 700,770 pediatric inpatients (mean age = 9.32 years) were included in this analysis. To explore potential disparities among children with symptoms in this area of clinical overlap, we assessed the relationship of "race" and the diagnosis of DBDs. Among the subgroup of pediatric inpatients diagnosed with ADHD or a DBD, Native American (OR = 2.18; 95% = 1.76, 2.70), Asian (OR = 1.88, 95% = 1.56, 2.26), Black (OR = 1.40; 95% = 1.32, 1.48), and Hispanic (OR = 1.20; 95% = 1.12, 1.28) "race" correlated with DBD diagnosis. By highlighting these diagnostic disparities, this study raises essential questions about race and the diagnosis of DBDs.

Organic cation transporter 1 in the lacrimal gland facilitates the entry of systemic drugs causing ocular surface toxicity.

Many of the daily systemic medications (parenteral and oral) used to treat various diseases are known to cause ocular toxicities - leading to vision loss. How these medications gain entry into the eye despite the ocular barriers is an important question to be addressed. Various reports show almost 30-40 % of systemic drugs causing ocular toxicity are organic cation in nature. We hypothesize these systemic drugs (cations) are non-specifically recognized as endogenous substrates by organic cation transporter (OCT1) in the lacrimal gland, thereby facilitating its entry into the anterior eye segment. Therefore, we studied the expression and localization of OCT1 in the lacrimal gland of rabbits. Further, to prove our hypothesis, OCT1 substrates (known as well as predicted from our previous Artificial Intelligence study) were administered intravenously in the presence and absence of topically administered OCT1 blockers. Our findings show, OCT1 gene and protein expression in the lacrimal gland, with its localization in the terminal acinar cells. The tear levels of intravenously administered substrates decreased in the presence of topical OCT1 blockers, indicating - a) the entry of systemic drugs into the eye via lacrimal secretion and b) OCT1 in the lacrimal gland is involved in the drug transport (substrates) from blood to the eye. Though the role of transporters in toxicity is well-known, the current study opens a new avenue for understanding the role of transporters in ocular toxicity.

Immune prognostic score predicts the risk of infection and survival outcomes in patients with relapsed multiple myeloma treated with bispecific antibodies.

The Glasgow prognostic score (GPS) and CAR-HEMATOTOX (CAR-HT) score identify multiple myeloma (MM) patients at high risk for immune-mediated toxicity and early mortality with cellular immunotherapy. However, their association with outcomes in patients receiving T-cell redirecting bispecific antibodies (bsAb) is unclear. This multi-centre retrospective study examines the association of baseline GPS and CAR-HT scores with outcomes in 126 MM patients treated with bsAb. Overall, 19% were identified as GPS high risk but did not experience increased toxicity or mortality. Conversely, high-risk CAR-HT patients had a higher incidence of infections and inferior survival, suggesting a need for aggressive infection mitigation strategies.

Understanding the impact of community-based sun safety interventions on a college campus in Texas.

Objective: Examine the impact of a community-based, multi-component sun intervention on the campus of Lee College in Baytown, Texas. Participants: 735 respondents completed the survey as part of a range of campus topics. Methods: Survey data on the program were gathered through an emailed campus-wide survey to better understand the community's perceptions and awareness as well as campaign effectiveness over time. Results: Sun safety self-efficacy and awareness of the importance of sun safety behaviors were high in the community. Students reported a lower level of sun safety self-efficacy than employees. Open-ended responses also offered insight into complex views some community members hold about sun-safety behavior, raising questions about the effectiveness of sunscreen and the need for vitamin D. Conclusions: The paper found high awareness of sun-safe behaviors, high self-efficacy in taking personal action, and appreciation for the institutional effort to care for the community.

Implementation and Evaluation of a Multi-level, Place-Based Tobacco Prevention and Control Program at a Minority-Serving Institution in Texas.

Multi-level, place-based interventions have proven effective at promoting a range of health behaviors, including tobacco control and discouraging the uptake of tobacco products. This paper describes the implementation and impact of a 3-year, multi-level tobacco prevention and control program at a community-college minority-serving institution (MSI) on the Texas Gulf Coast within the context of a broader multi-sector, cross-functional health coalition. The intervention studied included a tobacco-free policy, a large-scale communication campaign highlighting parts of the intervention and prevention and cessation resources. The intervention was bolstered by the support of a community-led Steering Committee and tobacco control experts. Results from the first 3 years of implementation show that tobacco-free policies were largely supported by community members, awareness of the policy increased over time, and tobacco prevention and cessation resources were successfully embedded into campus norms. This multi-component approach shows how a community college was able to effectively reach students and staff on their campus to increase awareness of both the campus tobacco-free policy and the availability of tobacco prevention and cessation resources. Additionally, it also offers lessons for future tobacco prevention and control work in higher education.

Linvoseltamab for Treatment of Relapsed/Refractory Multiple Myeloma.

PURPOSE: We present a phase I/II first-in-human trial evaluating the safety and efficacy of 50 mg and 200 mg doses of linvoseltamab, a B-cell maturation antigen × CD3 bispecific antibody in relapsed/refractory multiple myeloma (RRMM). METHODS: Phase II eligible patients had RRMM that either progressed on/after ≥three lines of therapy including a proteasome inhibitor (PI), an immunomodulatory drug (IMiD), and an anti-CD38 antibody or was triple-class (PI/IMiD/anti-CD38) refractory. Phase II treatment was once a week through week 14 and then once every 2 weeks. Phase II 200 mg patients who achieved a ≥very good partial response by week 24 received linvoseltamab once every 4 weeks. The primary end point in phase II was overall response rate (ORR). RESULTS: Among the 117 patients treated with 200 mg, the median age was 70 years, 39% had high-risk cytogenetics, and 28% had penta-refractory disease. At a median follow-up of 14.3 months, the ORR was 71%, with 50% achieving ≥complete response (CR). In 104 patients treated with 50 mg at a median follow-up of 7.4 months, the ORR was 48%, with 21% achieving ≥CR. The median duration of response (DOR) for 200 mg patients (n = 83) was 29.4 months (95% CI, 19.2 to not evaluable). Among 200 mg patients, the most common adverse events included cytokine release syndrome (35.0% Gr1, 10.3% Gr2, 0.9% Gr3), neutropenia (0.9% Gr2, 18.8% Gr3, 23.1% Gr4), and anemia (3.4% Gr1, 4.3% Gr2, 30.8% Gr3). Immune effector cell-associated neurotoxicity syndrome occurred in 7.7% of patients (2.6% each Gr1, Gr2, Gr3). Infections were reported in 74.4% of patients (33.3% Gr3, 2.6% Gr4); infection frequency and severity declined over time. CONCLUSION: Linvoseltamab 200 mg induced deep and durable responses, with a median DOR of 29.4 months, in patients with RRMM with an acceptable safety profile.

Health Communication in an Era of Disinformation: Perceived Source Credibility Among Transgender and Gender Diverse Individuals.

This study examines perceived source credibility of health information in a moment of TGD health disinformation. Through thematic analysis of in-depth interviews with 30 transgender and gender diverse (TGD) individuals, findings suggest health information is marred by anti-TGD legislation, a sociopolitical force that bleeds into health information spaces. Disinformation and TGD health communication are intertwined in complex ways, whereby disinformation can undermine trust in healthcare institutions, lead to harmful behaviors, and contribute to the spread of diseases. Health communication practitioners need to center the safety and humanity of TGD people, addressing TGD health disinformation.

Disparities in PI3K/mTOR inhibitor use, toxicities, and outcomes among patients with metastatic breast cancer.

PURPOSE: Novel agents such as PI3K and mTOR inhibitors (PI3K/mTORi) have expanded treatment options in metastatic breast cancer (MBC). Nevertheless, mortality rates remain disproportionately high for Black patients and patients with lower socioeconomic status. Furthermore, clinical trials for these novel agents lacked diversity, so their toxicity profile in minority populations is uncertain. METHODS: We conducted a retrospective analysis of EHR-derived data from the Flatiron Health Database for patients with HR+, HER2- MBC. Multivariable logistic regression was used to evaluate factors associated with PI3K/mTORi use and toxicity outcomes. RESULTS: A total of 9169 patients with MBC were included in our analysis, of which 1780 (19.4%) received a PI3K/mTORi. We estimated the conditional total effect of insurance through Medicaid, and found lower odds of use of PI3K/mTORi among patients on Medicaid compared to those with commercial insurance (OR 0.73, 95% CI 0.54-0.99, p = 0.049). Odds of PI3K/mTORi use were higher for patients treated at an academic center (OR 1.28, CI 1.06-1.55, p = 0.01). Modeled as a controlled direct effect, Black/African American (Black/AA) race had no impact on odds of PI3K/mTOR use. Black/AA patients had twice the odds of developing hyperglycemia on PI3K/mTORi compared to White patients (OR 2.02, CI 1.24-3.39, p < 0.01). CONCLUSION: This analysis of real-world data suggests that the use of PI3K/mTORi is influenced by socioeconomic factors. We also found racial disparities in toxicity outcomes, with Black/AA patients having twice the risk of hyperglycemia. Our findings call for greater efforts to ensure access to novel treatments and improve their tolerability in diverse populations.

Examining the Impact of Group-Based Social Skills Intervention in Autistic Children Aged Eight to 15 Years.

Introduction Autism spectrum disorder (ASD) is a neurological and developmental disorder, which poses challenges to social communication and behavior, particularly affecting social functioning. Individuals with ASD face significant social challenges, including difficulty understanding social cues and body language, limited ability to engage in reciprocal social interactions, and challenges with establishing empathy. A preference for routines and repetitive behaviors limits their ability to adapt to new or unexpected social situations. These problems tend to escalate during adolescence. These often cause distress to the individual as well as the caregivers. Group-based social skills interventions (GSSIs) are a widely used and effective modality for addressing core social impairments in children with autism. This study aims to assess the impact of GSSI on the broad age group of eight to 15 years, involving parents to enhance the transferability of children's social skills. Methods This was a single-arm interventional study where 30 verbal autistic children, aged eight to 15 years, with intelligence quotient (IQ) > 70 were enrolled after utilizing the Binet Kamat Test of Intelligence (BKT) to assess IQ and the Indian Scale for Assessment of Autism (ISAA) to grade severity of autism. The children received GSSI from interdisciplinary therapists for 12 sessions, on a weekly basis, lasting 90 minutes each for a period of three months. After each therapy session, parents received summaries of each session and were delegated reinforcing homework assignments to enable generalization and maintenance of the skills taught. Outcome measures were taken at three points in time by utilizing the Social Communication Questionnaire (SCQ) and the parent-rated Social Responsiveness Scale 2 (p-SRS-2): T1: pre-therapy at the time of enrolment; T2: immediately post-therapy at the end of three months of training; and T3: long-term follow-up, three months after the end of training. Results Mean SCQ scores were as follows: T1 = 21.87, T2 = 18.57, and T3 = 18.57 (p = 0.000). This progressive decline at T1, T2, and T3 indicated a decreasing trend in the severity of difficulties in the social communication domain. Mean p-SRS-2 scores were as follows: T1 = 73.00, T2 = 64.57, and T3 = 64.30 (p < 0.0001). This declining trend at T1, T2, and T3 suggested a statistically significant decrease in the severity of difficulties faced in various social aspects tested by the p-SRS-2, i.e., social awareness, social cognition, social communication, and social motivation, along with a reduction in restricted interests and repetitive behaviors (RRBs). Very strong correlation coefficients were obtained for SCQ scores (T1-T2 = 0.921, T1-T3 = 0.921, and T2-T3 = 1.000), as well as for p-SRS-2 scores (T1-T2 = 0.743, T1-T3 = 0.746, and T2-T3 = 0.989), which reinforced the statistical significance of the data. Conclusion GSSI is an effective parent-assisted intervention for adolescents with ASD, with effects lasting up to three months post-intervention.

Delayed Diagnosis of Human Immunodeficiency Virus in the Latino Population at a Federally Qualified Community Health Center in New Jersey.

Late diagnosis of human immunodeficiency virus (HIV) is associated with early progression to acquired immunodeficiency syndrome (AIDS). We examined racial/ethnic differences in presentation with advanced HIV/AIDS at a community health center in New Jersey. Records of patients diagnosed with HIV between 1990 and 2018 were reviewed. Odds ratios (OR) of presenting with AIDS at HIV diagnosis were computed in unadjusted and adjusted models. There were 182 (48.3%) Latino, 48 (12.7%) non-Latino White (NLW), 130 (34.5%) non-Latino Black, and 17 (4.5%) non-Latino of other race/ethnicity included in the analysis. Over 75% of the Latinos were foreign-born. Latino patients had higher odds of presentation with AIDS at time of HIV diagnosis than NLW in unadjusted (OR = 4.85, 95% confidence interval (95% CI): 2.28-10.31) and adjusted models (OR = 3.71, 95%CI: 1.60-8.59). Latino patients, particularly foreign-born and bisexual, had higher odds of being diagnosed with AIDS at presentation with HIV in this cohort.

PEGylated Polymeric Nanoparticles Loaded with 2-Methoxyestradiol for the Treatment of Uterine Leiomyoma in a Patient-Derived Xenograft Mouse Model.

Leiomyomas, the most common benign neoplasms of the female reproductive tract, currently have limited medical treatment options. Drugs targeting estrogen/progesterone signaling are used, but side effects and limited efficacy in many cases are major limitation of their clinical use. Previous studies from our laboratory and others demonstrated that 2-methoxyestradiol (2-ME) is promising treatment for uterine fibroids. However, its poor bioavailability and rapid degradation hinder its development for clinical use. The objective of this study is to evaluate the in vivo effect of biodegradable and biocompatible 2-ME-loaded polymeric nanoparticles in a patient-derived leiomyoma xenograft mouse model. PEGylated poly(lactide-co-glycolide) (PEG-PLGA) nanoparticles loaded with 2-ME were prepared by nanoprecipitation. Female 6-week age immunodeficient NOG (NOD/Shi-scid/IL-2Rγnull) mice were used. Estrogen-progesterone pellets were implanted subcutaneously. Five days later, patient-derived human fibroid tumors were xenografted bilaterally subcutaneously. Engrafted mice were treated with 2-ME-loaded or blank (control) PEGylated nanoparticles. Nanoparticles were injected intraperitoneally and after 28 days of treatment, tumor volume was measured by caliper following hair removal, and tumors were removed and weighed. Up to 99.1% encapsulation efficiency was achieved, and the in vitro release profile showed minimal burst release, thus confirming the high encapsulation efficiency. In vivo administration of the 2-ME-loaded nanoparticles led to 51% growth inhibition of xenografted tumors compared to controls (P < 0.01). Thus, 2-ME-loaded nanoparticles may represent a novel approach for the treatment of uterine fibroids.

Social determinants of health and CDK4/6 inhibitor use and outcomes among patients with metastatic breast cancer.

BACKGROUND: Survival outcomes in metastatic breast cancer (MBC) have improved due to novel agents such as CDK4/6 inhibitors (CDK4/6i). Nevertheless, Black patients and patients with lower socioeconomic status (SES) continue to bear a disproportionate mortality burden. METHODS: We conducted a retrospective analysis of EHR-derived data from the Flatiron Health Database (FHD). A dataset was constructed to include Black/African-American (Black/AA) and White patients with hormone receptor (HR)-positive, HER2-negative MBC. Outcomes included CDK4/6i use (overall and first-line), and rates of leukopenia, dose reduction, and time on treatment for first-line CDK4/6i. Multivariable logistic regression was used to evaluate factors associated with use and outcomes. RESULTS: A total of 6802 patients with MBC were included, of which 5187 (76.3%) received CDK4/6i. Of those, 3186 (61.4%) received CDK4/6i first-line. Overall, 86.7% of patients were categorized as White and 13.3% as Black/AA; 22.4% were > 75 years old; 12.6% were treated at an academic site; 3.3% had Medicaid insurance. In addition to advanced age and poorer performance status, lower use of CDK4/6i was associated with Black/AA vs White race (72.9% vs 76.8%; OR 0.83, 95% CI 0.70-0.99, p = 0.04) and Medicaid vs commercial insurance (69.6% vs 77.4%; OR: 0.68, 95% CI 0.49-0.95, p = 0.02). Odds of CDK4/6i use were twofold higher for patients treated at an academic center (p < 0.001). Rates of CDK4/6i-induced leukopenia and dose reductions did not differ significantly by race, insurance type, or treatment site. Time on CDK4/6i was significantly lower among Medicaid patients (395 days) than patients with commercial insurance (558 days) or Medicare (643 days) (p = 0.03). CONCLUSION: This analysis of real-world data suggests that Black race and lower SES are associated with decreased CDK4/6i use. However, among patients treated with CDK4/6i, subsequent toxicity outcomes are similar. Efforts to ensure access to these life-prolonging medications are warranted.

Challenges and Opportunities in Antimicrobial Stewardship among Hematopoietic Stem Cell Transplant and Oncology Patients.

Antimicrobial stewardship programs play a critical role in optimizing the use of antimicrobials against pathogens in the era of growing multi-drug resistance. However, implementation of antimicrobial stewardship programs among the hematopoietic stem cell transplant and oncology populations has posed challenges due to multiple risk factors in the host populations and the infections that affect them. The consideration of underlying immunosuppression and a higher risk for poor outcomes have shaped therapeutic decisions for these patients. In this multidisciplinary perspective piece, we provide a summary of the current landscape of antimicrobial stewardship, unique challenges, and opportunities for unmet needs in these patient populations.

Peripheral Ulcerative Keratitis as a Manifestation of Drug-Induced Cicatrizing Conjunctivitis.

Ocular surface drug toxicity due to the long-term use of topical medication is a commonly overlooked cause of chronic conjunctival inflammation. A variety of eye drops, including but not limited to anti-glaucoma medications can cause drug-induced cicatrizing conjunctivitis. The classical descriptions of this condition include inflammation and scarring involving the eyelids, puncta, and conjunctiva. Herein, we present a case with bilateral peripheral ulcerative keratitis as a manifestation of drug-induced cicatrizing conjunctivitis.

Low c-Kit expression identifies primitive, therapy-resistant CML stem cells.

Despite the efficacy of tyrosine kinase inhibitors (TKIs) in chronic myeloid leukemia (CML), malignant long-term hematopoietic stem cells (LT-HSCs) persist as a source of relapse. However, LT-HSCs are heterogenous and the most primitive, drug-resistant LT-HSC subpopulations are not well characterized. In normal hematopoiesis, self-renewal and long-term reconstitution capacity are enriched within LT-HSCs with low c-Kit expression (c-KITlo). Here, using a transgenic CML mouse model, we found that long-term engraftment and leukemogenic capacity were restricted to c-KITlo CML LT-HSCs. CML LT-HSCs demonstrated enhanced differentiation with expansion of mature progeny following exposure to the c-KIT ligand, stem cell factor (SCF). Conversely, SCF deletion led to depletion of normal LT-HSCs but increase in c-KITlo and total CML LT-HSCs with reduced generation of mature myeloid cells. CML c-KITlo LT-HSCs showed reduced cell cycling and expressed enhanced quiescence and inflammatory gene signatures. SCF administration led to enhanced depletion of CML primitive progenitors but not LT-HSCs after TKI treatment. Human CML LT-HSCs with low or absent c-KIT expression were markedly enriched after TKI treatment. We conclude that CML LT-HSCs expressing low c-KIT levels are enriched for primitive, quiescent, drug-resistant leukemia-initiating cells and represent a critical target for eliminating disease persistence.

Coupling-Condensation Strategy for the Convergent Synthesis of an Imidazole-Fused 2-Aminoquinoline NLRP3 Agonist.

The development of a convergent route to the NLRP3 (nucleotide-binding domain and leucine-rich repeat-containing protein 3) agonist BMS-986299 is reported. The synthesis relies on a key Miyaura borylation and a tandem Suzuki-Miyaura coupling between an iodoimidazole and an o-aminochloroarene, followed by acid-mediated cyclization to afford the aminoquinoline core. The subsequent Boc cleavage and regioselective acylation afford the target compound. Two routes to the iodoimidazole intermediate are presented, along with the synthesis of the o-aminochloroarene via Negishi coupling. The convergent six-step route leads to an 80% reduction in process mass intensity compared to the linear enabling synthesis.

Serum Sickness like Reaction Postequine Rabies Immunoglobulins.

A 30-year-old, previously healthy adult male received equine rabies immunoglobulins (Ig) (ERIG) along with anti-rabies vaccinations as per protocol for postexposure prophylaxis after an unprovoked rabid dog bite of grade three wound over the shin of the left lower limb. On the 8th day, he developed urticarial rashes beginning from the site of the wound, which gradually became a widespread maculopapular rash. Development of the rash was followed by low-grade fever, nonspecific arthralgias and soreness in the throat. A diagnosis of serum sickness-like illness was made based on history, temporal correlation of administration of ERIG and development of symptoms. He responded well to antihistaminic and a short course of injectable steroids. The purpose of this article is to increase awareness regarding the clinical presentation and management of this rare yet potentially curable adverse event if identified timely.

Squamous cell carcinoma (SCC) has a good prognosis, while metastatic tumors have aggressive behavior. Immunotherapy has become a standard line of treatment in metastatic cancers; pembrolizumab has shown promising results and improved quality of life in recurrent and metastatic cancers. We report a case of recurrent SCC of the skin with extensive disease and a known case of human immunodeficiency virus. He completed standard lines of treatment and currently on immunotherapy. After 3 cycles of immunotherapy plus chemotherapy, he got a complete metabolic response. Our experience showed palliative benefits and increased quality of life.

Effect of cotton dust on lungs among female workers in cotton industry in northern Gujarat, India.

Byssinosis is a disabling occupational lung disease caused by cotton dust. It is a well-known occupational respiratory disease in cotton industry workers caused by cotton dust pollution. Many studies have been documented the effects of cotton dust on pulmonary function among workers employed in cotton-spinning mills. However, little data exist on the prevalence of this disorder in female workers particularly in western part of India. The present study was conducted to analyze the effects of exposure to cotton dust on pulmonary functions among female workers. The study was designed to assess the effects of exposure to cotton dust on lung functions among female cotton industry workers. Study group comprises 50 Female workers of cotton industry and control group comprises 50 age matched females who were neither worked in cotton industry nor exposed to cotton dust. Information was collected using standardized questionnaires, physical examination and spirometric measurements. Student's T test was used to find the difference between spirometric parameters. All the respiratory parameters (FVC, FEV1, FEV1/FVC ratio, FEF 25-75 % PEFR and MVV) were reduced in cotton industry workers as compared with control subjects (p<0.0001) and no significant difference of SpO2 between groups. Cotton dust exposure makes huge impact on respiratory parameters of the cotton industry workers. This deterioration in respiratory health deteriorates with increasing duration of exposure. The health hazards caused by cotton dust should be controlled by creating awareness among the workers & employers.
