RESUMEN
Background: Insufficient sleep and insomnia are associated with alcohol use as well as anxiety during adolescence and young adulthood. A negative reinforcement path to explain the association between sleep difficulties and alcohol misuse has been proposed. Within this pathway, it is speculated that while sober, insomnia and insufficient sleep lead to increased anxiety as well as anxiolytic responses to alcohol, thereby increasing the risk for both alcohol use and alcohol use problems. No work to date has examined the negative reinforcement path to alcohol use among adolescents who have consumed alcohol. Objectives: The current study aims to address this gap in the literature by examining if sleep quality is related to adolescent alcohol use problems and frequency through serial indirect effects of adolescent anxiety symptoms and coping motives for alcohol use. A total of 147 adolescents between the ages of 13 and 18 years (Mage = 16.31; SD = 0.96) from all geographic regions in the US were recruited using social media platforms (i.e., Facebook and Instagram). Participants who reported having tried alcohol at least once completed self-report measures to examine sleep quality, anxiety symptoms, alcohol use problems, alcohol use frequency, and coping motives for alcohol use. Results: Adolescent sleep quality was found to be associated with higher levels of both alcohol use problems and alcohol use frequency through the serial indirect effect of anxiety symptoms and coping motives for alcohol use. Conclusions: Overall, these findings represent a step towards understanding the complex relationship between sleep quality, alcohol, anxiety, and coping motives among adolescents.

BACKGROUND & AIMS: Interleukin (IL)33/IL1F11 is an important mediator for the development of type 2 T-helper cell (Th2)-driven inflammatory disorders and has also been implicated in the pathogenesis of gastrointestinal (GI)-related cancers, including gastric carcinoma. We therefore sought to mechanistically determine IL33's potential role as a critical factor linking chronic inflammation and gastric carcinogenesis using gastritis-prone SAMP1/YitFc (SAMP) mice. METHODS: SAMP and (parental control) AKR mice were assessed for baseline gastritis and progression to metaplasia. Expression/localization of IL33 and its receptor, ST2/IL1R4, were characterized in corpus tissues, and activation and neutralization studies were both performed targeting the IL33/ST2 axis. Dissection of immune pathways leading to metaplasia was evaluated, including eosinophil depletion studies using anti-IL5/anti-CCR3 treatment. RESULTS: Progressive gastritis and, ultimately, intestinalized spasmolytic polypeptide-expressing metaplasia (SPEM) was detected in SAMP stomachs, which was absent in AKR but could be moderately induced with exogenous, recombinant IL33. Robust peripheral (bone marrow) expansion of eosinophils and local recruitment of both eosinophils and IL33-expressing M2 macrophages into corpus tissues were evident in SAMP. Interestingly, IL33 blockade did not affect bone marrow-derived expansion and local infiltration of eosinophils, but markedly decreased M2 macrophages and SPEM features, while eosinophil depletion caused a significant reduction in both local IL33-producing M2 macrophages and SPEM in SAMP. CONCLUSIONS: IL33 promotes metaplasia and the sequelae of eosinophil-dependent downstream infiltration of IL33-producing M2 macrophages leading to intestinalized SPEM in SAMP, suggesting that IL33 represents a critical link between chronic gastritis and intestinalizing metaplasia that may serve as a potential therapeutic target for preneoplastic conditions of the GI tract.

People who inject drugs (PWIDs) are a key population targeted in global efforts to increase HIV and Hepatitis C virus (HCV) diagnosis, linkage to care, and treatment retention. Colombia has experienced a significant increase in the incidence of HIV and HCV attributed to the alarming rise in injection drug use. The primary aim of this study was to identify factors influencing access to HIV and HCV care among PWIDs. Survey domains consisted of (1) sociodemographic characteristics; (2) history of HIV-HCV testing and infection status; (3) the 13-item questionnaire developed by Awad and colleagues to explore barriers to HIV and HCV testing, (4) the Barriers to Medical Care questionnaire; and (5) the Risk Assessment Battery. A total of 171 subjects completed the survey. A high proportion of participants reported past year testing for HIV (87%) and HCV (72.8%). However, most respondents elicited numerous barriers to obtaining information, referrals, and insurance coverage for accessing HIV and/or HCV care. Further studies are needed to identify scalable public health measures to overcome these barriers.

PURPOSE: Improved outcomes in lung cancer treatment are seen in high-volume academic centers, making it important to understand barriers to accessing care at such institutions. Few qualitative studies examine the barriers and facilitators to early-stage lung cancer care at US academic institutions. METHODS: Adult patients with suspected or diagnosed early-stage non-small cell lung cancer presenting to a multidisciplinary lung cancer clinic at a US academic institution over a 6-month period beginning in 2019 were purposively sampled for semi-structured interviews. Semi-structured interviews were conducted and a qualitative content analysis was performed using the framework method. Themes relating to barriers and facilitators to lung cancer care were identified through iterative team-based coding. RESULTS: The 26 participants had a mean age of 62 years (SD: 8.4 years) and were majority female (62%), white (77%), and urban (85%). We identified 6 major themes: trust with providers and health systems are valued by patients; financial toxicity negatively influenced the diagnostic and treatment experience; social constraints magnified other barriers; patient self-advocacy as a facilitator of care access; provider advocacy could overcome other barriers; care coordination and good communication were important to patients. CONCLUSIONS: We have identified several barriers and facilitators to lung cancer care at an academic center in the US. These factors need to be addressed to improve quality of care among lung cancer patients. Further work will examine our findings in a community setting to understand if our findings are generalizable to patients who do not access a tertiary cancer care center.

INTRODUCTION: Adolescence is characterized by the onset of a relatively specific set of socioemotional disorders (i.e., depression, generalized anxiety disorder, social anxiety disorder, and eating disorders) as well as body dysmorphia symptoms. Appearance-related concerns are a central feature of these disorders. Emerging evidence in adults suggests that appearance-related safety behaviors may play an instrumental role in the onset and maintenance of a number of disorders. To date, no work has examined appearance-related safety behaviors during adolescence. The present study examined the extent to which appearance-related safety behaviors may be associated with socioemotional and body dysmorphia symptoms during adolescence. METHODS: Adolescents between the ages of 13 and 17 years old (N = 387, Mage = 14.82 years, 31.3% identified as male, 47.0% identified as female, and 19.1% identified as nonbinary/third gender, 2.6% declined to report gender identity) completed measures assessing negative affect, anxiety-relevant safety behavior use, cognitive reappraisal, expressive suppression, appearance-related safety behaviors, body dysmorphia symptoms, and socioemotional symptoms. Structural Equation Modeling was used to test hypotheses. RESULTS: The results of this study suggest that appearance-related safety behaviors evidenced associations with latent factors corresponding to affective (i.e., depression, generalized anxiety disorder, social anxiety), eating disorders, and body dysmorphia symptoms after controlling for previously established vulnerability factors. CONCLUSIONS: These findings demonstrate that appearance-related safety behaviors may evidence transdiagnostic associations with socioemotional symptoms and body dysmorphia symptoms during adolescence.

Both maternal symptoms and adolescent offspring characteristics are associated with maladaptive parenting among families at risk for anxiety. One disorder that may be particularly associated with maladaptive parenting behaviors is generalized anxiety disorder (GAD). Previous work suggests that offspring negative affect (NA) is associated with different levels of maladaptive parenting behaviors among mothers with GAD. No work to date, however, has examined the association between offspring reported NA, maternal GAD, and maternal worry about offspring or maternal perceptions of psychological control (PC) among mothers of adolescents. Sixty-five mothers who were elevated in anxious arousal and their adolescent offspring between the ages of 12 and 16 years old (n = 65, 55% male, Mage = 13.89) reported on parenting (mother report), NA (offspring report), and GAD symptoms (assessed via structured clinical interview), and maternal anxiety sensitivity (AS) symptoms. Study results indicated that maternal GAD status interacted with offspring NA in relation to maternal reported use of PC and worry about offspring. Specifically, offspring NA was positively related to PC for mothers without GAD, but not for mothers with GAD. Further, for mothers with GAD, offspring NA was negatively related to worry about offspring, but this relation did not persist for mothers without GAD. Maternal AS was related to overall higher levels of worry about offspring and PC. Mothers with GAD report using higher levels of maladaptive parenting when offspring report lower levels of NA, and lower levels when offspring report high NA. This pattern was specific to maternal GAD (c.f. anxiety sensitivity).

INTRODUCTION: Sleep disturbances are common among adolescents and are associated with elevated anxiety, and difficulties managing affect. Familial conflict is associated with both anxiety sensitivity and adolescent sleep disturbances. No work to date has examined how adolescent sleep disturbances may interact with anxiety sensitivity in relation to adolescent affective responding to parent-adolescent conflict. The current study was designed to address this gap in the literature by examining how adolescent sleep disturbances, anxiety sensitivity, conflict elicited anger, and conflict avoidance are associated. METHOD: Seventy-two American adolescents (n = 39 males) between the ages of 12 and 16 years (Mage = 13.84, SD = 1.38) completed a baseline assessment as well as a well-validated mother-adolescent laboratory-based conflict task. RESULTS: For youth low in anxiety sensitivity, greater sleep disturbance related positively to conflict-elicited anger, which in turn predicted higher conflict avoidance. In contrast, this indirect effect was not significant for adolescents relatively higher in anxiety sensitivity. Instead, for these adolescents, increased sleep disturbances were associated with lower levels of conflict elicited anger. CONCLUSIONS: Results suggest that the effects of sleep disturbances on conflict elicited anger may vary as a function of adolescent anxiety vulnerability. These findings highlight the importance of considering the unique effects of sleep disturbances on adolescent affect as a function of adolescent anxiety vulnerability.

We describe and implement an interferometric approach to decay-associated photoluminescence spectroscopy, which we term decay-associated Fourier spectroscopy (DAFS). In DAFS, the emitted photon stream from a substrate passes through a variable path length Mach-Zehnder interferometer prior to detection and timing. The interferometer encodes spectral information in the intensity measured at each detector enabling simultaneous spectral and temporal resolution. We detail several advantages of DAFS, including wavelength-range insensitivity, drift-noise cancellation, and optical mode retention. DAFS allows us to direct the photon stream into an optical fiber, enabling the implementation of superconducting nanowire single photon detectors for energy-resolved spectroscopy in the shortwave infrared spectral window (λ = 1-2 µm). We demonstrate the broad applicability of DAFS, in both the visible and shortwave infrared, using two Förster resonance energy transfer pairs: a pair operating with conventional visible wavelengths and a pair showing concurrent acquisition in the visible and the shortwave infrared regime.
RESUMEN
BACKGROUND: The prevalence of pediatric allergic diseases has increased rapidly in the United States over the past few decades. Recent studies suggest an association between the increase in allergic disease and early disturbances to the gut microbiome. The gut microbiome is a set of intestinal microorganisms that begins to form during birth and is highly susceptible to disturbance during the first year of life. Early antibiotic exposure may negatively impact the gut microbiota by altering the bacterial composition and causing dysbiosis, thus increasing the risk for developing childhood allergic disease. METHODS: We performed a retrospective chart review of data in Loyola University Medical Center's (LUMC) Epic system from 2007 to 2016. We defined antibiotic exposure as orders in both the outpatient and inpatient settings. Inclusion criteria were being born at LUMC with at least two follow up visits. Asthma and allergic rhinitis diagnoses were obtained using ICD 9 and ICD 10 codes. We controlled for multiple confounding factors. Using Stata, bivariate logistic regression was performed between antibiotics from 0 to 12 months of life and development of disease. This analysis was repeated for total lifetime antibiotics. We defined statistically significant as p < .05. RESULTS: The administration of antibiotics within the first 12 months of life was significantly associated with lifetime asthma (OR 2.66; C. I 1.11-6.40) but not allergic rhinitis. There was a significant association between lifetime antibiotics and asthma (OR 3.54; C. I 1.99-6.30) and allergic rhinitis (OR 2.43; C. I 1.43-4.11). CONCLUSION: Antibiotic administration in the first year of life and throughout lifetime is significantly associated with developing asthma and allergic rhinitis. These results provide support for a conservative approach regarding antibiotic use in early childhood.

There is a growing literature on children with autism spectrum disorder (ASD) who respond favorably to behavioral treatment, which is often termed "optimal outcome." Rates and definitions of optimal outcome vary widely. The current case series describes an empirically validated behavioral treatment approach called Pivotal Response Treatment (PRT). We present two preschool-aged children who received an intensive course of PRT and seem to be on a trajectory toward potential optimal outcome. Understanding response to treatment and predictors of response is crucial, not necessarily to predict who may succeed, but to individualize medicine and match children with customized treatment programs that will be best tailored to their unique and varied needs.

The current paper provides an overview of an evidence-based treatment, Pivotal Response Treatment (PRT), for autism spectrum disorder (ASD). The paper describes PRT principles and then illustrates the approach using two case reports. The children are preschool-aged children with high-functioning ASD. They were participating in a four-month clinical trial of PRT. At the start of treatment, they presented with significant social communication impairments, including a minimal understanding of reciprocity, limited play skills, and repetitive behaviors and speech. The paper outlines how behavioral treatment goals were identified and then how activities were designed, using principles of PRT, to target skill acquisition. Following the treatment course, both children made substantial and meaningful gains in social communication skill development.

Near infrared (NIR, 700-1000 nm) and short-wave infrared (SWIR, 1000-2000 nm) dye molecules exhibit significant nonradiative decay rates from the first singlet excited state to the ground state. While these trends can be empirically explained by a simple energy gap law, detailed mechanisms of nearly universal behavior have remained unsettled for many cases. Theoretical and experimental results for two representative NIR/SWIR dye molecules reported here clarify the key mechanism for the observed energy gap law behavior. It is shown that the first derivative nonadiabatic coupling terms serve as major coupling pathways for nonadiabatic decay processes from the first excited singlet state to the ground state for these NIR and SWIR dye molecules and that vibrational modes other than the highest frequency modes also make significant contributions to the rate. This assessment is corroborated by further theoretical comparison with possible alternative mechanisms of intersystem crossing to triplet states and also by comparison with experimental data for deuterated molecules.
RESUMEN
Between 1990 and 2020, 334 rural hospitals closed in the United States, and since 2011 hospital closures have outnumbered new hospital openings. This scoping review evaluates peer-reviewed studies published since 1990 with a focus on rural hospital closures, synthesizing studies across six themes: 1) health care policy environment, 2) precursors to rural hospital closures, 3) economic impacts, 4) effects of rural hospital closures on access to care, 5) health and community impacts, and 6) definitions of rural hospitals and communities. In the 1990s, rural hospitals that closed were smaller, while rural hospitals that closed in the 2010s tended to have more beds. Many studies of the health impacts of rural hospital closures yielded null findings. However, these studies differed in their definitions of "rural hospital closure." Given the accelerated rate of hospital closures, more attention should be paid to hospitals that serve rural communities of color and low-income communities.

The design of bright short-wave infrared fluorophores remains a grand challenge. Here we investigate the impact of deuteration on the properties in a series of heptamethine dyes, the absorption of which spans near-infrared and SWIR regions. We demonstrate that it is a generally applicable strategy that leads to enhanced quantum yields of fluorescence, longer-lived singlet excited states and suppressed rates of non-radiative deactivation processes.
RESUMEN
In vivo fluorescence imaging in the shortwave infrared (SWIR, 1,000-1,700 nm) and extended SWIR (ESWIR, 1,700-2,700 nm) regions has tremendous potential for diagnostic imaging. Although image contrast has been shown to improve as longer wavelengths are accessed, the design and synthesis of organic fluorophores that emit in these regions is challenging. Here we synthesize a series of silicon-RosIndolizine (SiRos) fluorophores that exhibit peak emission wavelengths from 1,300-1,700 nm and emission onsets of 1,800-2,200 nm. We characterize the fluorophores photophysically (both steady-state and time-resolved), electrochemically and computationally using time-dependent density functional theory. Using two of the fluorophores (SiRos1300 and SiRos1550), we formulate nanoemulsions and use them for general systemic circulatory SWIR fluorescence imaging of the cardiovascular system in mice. These studies resulted in high-resolution SWIR images with well-defined vasculature visible throughout the entire circulatory system. This SiRos scaffold establishes design principles for generating long-wavelength emitting SWIR and ESWIR fluorophores.

PURPOSE: To test the hypothesis that fractional kidney hypoxia, measured by using blood oxygen level-dependent (BOLD) magnetic resonance (MR) imaging, correlates with renal blood flow (RBF), tissue perfusion, and glomerular filtration rate (GFR) in patients with atherosclerotic renal artery stenosis (RAS) better than regionally selected region of interest-based methods. MATERIALS AND METHODS: The study was approved by the institutional review board according to a HIPAA-compliant protocol, with written informed consent. BOLD MR imaging was performed in 40 patients with atherosclerotic RAS (age range, 51-83 years; 22 men, 18 women) and 32 patients with essential hypertension (EH) (age range, 26-85 years; 19 men, 13 women) during sodium intake and renin-angiotensin blockade. Fractional kidney hypoxia (percentage of entire axial image section with R2* above 30 sec(-1)) and conventional regional estimates of cortical and medullary R2* levels were measured. Stenotic and nonstenotic contralateral kidneys were compared for volume, tissue perfusion, and blood flow measured with multidetector computed tomography. Statistical analysis was performed (paired and nonpaired t tests, linear regression analysis). RESULTS: Stenotic RBF was reduced compared with RBF of contralateral kidneys (225.2 mL/min vs 348 mL/min, P = .0003). Medullary perfusion in atherosclerotic RAS patients was lower than in EH patients (1.07 mL/min per milliliter of tissue vs 1.3 mL/min per milliliter of tissue, P = .009). While observer-selected cortical R2* (18.9 sec(-1) [stenosis] vs 18.5 sec(-1) [EH], P = .07) did not differ, fractional kidney hypoxia was higher in stenotic kidneys compared with kidneys with EH (17.4% vs 9.6%, P < .0001) and contralateral kidneys (7.2%, P < .0001). Fractional hypoxia correlated inversely with blood flow (r = -0.34), perfusion (r = -0.3), and GFR (r = -0.32). CONCLUSION: Fractional tissue hypoxia rather than cortical or medullary R2* values used to assess renal BOLD MR imaging demonstrated a direct relationship to chronically reduced blood flow and GFR.

BACKGROUND: Recent studies have shown that magnetic resonance imaging (MRI) of patients with pacemakers can be safely performed under careful monitoring, but they excluded patients with recently implanted devices. Patients with recent implants may be at a greater risk for complications during MRI imaging due to lack of lead and wound maturity. METHODS: We implemented a clinical protocol for MRI imaging of patients with implanted cardiac devices, and prospectively collected data. For this study, we retrospectively analyzed two groups of patients: those with recently implanted (≤42 days) and nonrecently implanted (>42 days) leads at the time of MRI scanning. All devices were interrogated before and after scanning, and were reprogrammed during the scan as per protocol. RESULTS: Of the 219 scans (in 171 patients), eight included patients with recently implanted (range: 7-36 days) and 211 with only nonrecently implanted pacemaker leads. During the scan, there were no complications in the early or late group. In one patient imaged 79 days postimplant, frequent premature ventricular complexes were noted during the scan, requiring no action. No patient reported pain during or immediately after the procedure. No clinically significant changes in function were seen at subsequent follow up (average 104 days post-MRI). Compared to patients with nonrecently implanted leads, there was no difference in any parameter between the two groups. CONCLUSIONS: With a strong clinical indication and with careful monitoring, MRI imaging is feasible in patients with recently implanted pacemakers, although experience is limited.

OBJECTIVE: To determine whether rural Medicare FFS beneficiaries are more likely to be admitted to an urban hospital in 2018 than in 2010. DATA SOURCES: We combined data from the 2010 to 2018 Hospital Service Area File (HSAF) and the 2010-2017 American Hospital Association (AHA) survey. STUDY DESIGN: We conducted a fixed-effects negative-binomial regression to determine whether urban hospital admissions from rural ZIP codes were increasing over time. We also conducted an exploratory geographically weighted regression. DATA COLLECTION: We transformed the HSAF data into a ZIP code-level file with all rural ZIP codes. We defined rural as having a Rural-Urban Commuting Area (RUCA) code ≥4. A hospital's system affiliation status was incorporated from the AHA survey. PRINCIPAL FINDINGS: Controlling for distance to the nearest hospitals, an increase of 1 year was associated with a 2.0% increase (p < 0.001) in the number of admissions to urban hospitals from each rural ZIP code. New system affiliation of the nearest rural hospital was associated with an increase of 1.7% (p < 0.001). CONCLUSIONS: Even when controlling for distance to the nearest rural hospital (which reflects hospital closures), rural patients were increasingly likely to be admitted to an urban hospital.

Much research has demonstrated that psychopathology can be described in terms of broad dimensions, representing liability for multiple psychiatric disorders. Broad spectra of psychopathology (e.g., internalizing and externalizing) are increasingly used as targets for research investigating the development, etiology, and course of psychopathology because they account for patterns of relatedness among disorders that were once presumed distinct. Thus, these spectra represent alluring targets due to their comprehensive and parsimonious nature. Nevertheless, little research has established the role of individual disorders over and above broad dimensions in the study of psychopathology. In the current study, we investigate whether there are unique etiological associations between individual internalizing disorders and personality traits after accounting for their etiological associations with a broad internalizing dimension. We used a community sample of twins (Npairs = 448) ages 4 to 19 to examine the etiological associations between internalizing psychopathology and Big Five personality dimensions. In terms of genetic covariation, a broad internalizing dimension was positively associated with neuroticism and negatively associated with extraversion, agreeableness, and conscientiousness. Moreover, internalizing accounted for most of the genetic variance shared between individual internalizing disorders and personality traits. Nevertheless, there were unique genetic associations between the following pairs of personality traits and disorders: neuroticism and social anxiety, extraversion and social anxiety, agreeableness and depression, and conscientiousness and compulsions. There was little evidence of environmental influences shared between internalizing and personality. In sum, a broad internalizing dimension adequately accounted for almost all of the etiologic covariation between internalizing disorders and personality, with several interesting exceptions.

Introduction: The COVID-19 pandemic has created unique challenges for primary care practices while also highlighting their importance in the pandemic response. To understand primary care practice needs, a survey was conducted of practices in Western North Carolina. Methods: Phase 2 of a primary care needs assessment was administered to 63 practices in Western North Carolina over the course of six weeks, from July 23 to August 31, 2021. Results: Most practices were operating with normal hours, though some still operated with reduced hours. Many practices reported insufficient personal protective equipment (PPE) supplies. While most practices provided at least some care via telehealth, practices cited different barriers to providing telehealth, with patient technology challenges being the most frequently cited. Discussion: Practices have adapted to the restrictions of the pandemic, but many are still vulnerable, and the patients they serve may face reduced access to care due to practice limitations or barriers to telehealth. Practices play a critical role in providing care to patients throughout the pandemic and continue to assist in pandemic response by providing COVID-19 testing and other services. Conclusion: Primary care practices in Western North Carolina continue to provide care to patients and support the overall pandemic response. The pandemic has highlighted the need to include primary care in emergency response efforts. Ongoing work will allow North Carolina to reach practices more effectively in future crises via the newly created NC Responds system, which allows primary care practices to be contacted in the event of a public health emergency.
