AbstractObjectivesImmunosuppressed paediatric patients with rheumatic disease (RD) may be at risk for severe or critical disease related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Data remain scarce on coronavirus disease 2019 (COVID-19) outcomes in paediatric RD patients. The aim of this study was to determine the seroprevalence of SARS-CoV-2 IgG and to describe COVID-19 outcomes in immunosuppressed paediatric RD patients.MethodsPatients diagnosed with RD before age 18 years and treated with at least one immunosuppressive medication for at least 3 months were enrolled from a tertiary paediatric rheumatology practice in New York and also underwent routine SARS-CoV-2 IgG testing from May to November 2020. A total of 571 patients were screened and 262 were enrolled. SARS-CoV-2 IgG-positive subjects were assessed for symptoms of COVID-19 infection. SARS-CoV-2 PCR results were recorded where available. Demographic, diagnostic, medication and outcome data were collected.ResultsOf 262 subjects (186 female), 35 (13%) were SARS-CoV-2 IgG positive; 17 (49%) had symptoms suggestive of COVID-19. Of the 17 patients who had SARS-CoV-2 PCR testing, 11 (65%) were PCR positive, 7 of whom were IgG positive. Most SARS-CoV-2 IgG-positive subjects were not PCR tested. The most common symptoms in IgG- and/or PCR-positive subjects were fever, fatigue and cough. No SARS-CoV-2 IgG- or PCR-positive subject developed severe or critical COVID-19 or required hospitalization.ConclusionsThis is the first report of clinical outcomes of SARS-CoV-2 infection and seroprevalence of SARS-CoV-2 IgG in a large cohort of paediatric RD patients. Most SARS-CoV-2 IgG-positive subjects had no symptoms of COVID-19 infection. Symptomatic subjects all had mild COVID-19 symptoms, suggesting that the risk of severe or critical COVID-19 in immunosuppressed paediatric RD patients is minimal.

Abstract

Objective
Juvenile systemic sclerosis (JSSc) is a rare condition in childhood and its variety with no skin involvement, sine scleroderma (ssJSSc), is anecdotal. We report the first case series of patients with ssJSSc.

Methods
Demographic, clinical and laboratory data of patients with JSSc followed at our centre were retrospectively collected. Patients with no skin involvement but with all of the features RP, positive ANA, intestinal dysmotility and/or interstitial lung disease (ILD) or pulmonary arterial hypertension (PAH) and/or cardiac or renal involvement typical of scleroderma were defined as having ssJSSc and compared with those with classic JSSc (cJSSc).

Results
Among 52 JSSc patients seen in 20 years, five (9.6%) presented with ssJSSc. Their clinical features and those of the only two patients reported in the literature so far were compared with classic JSSc with available complete data. Six patients had cardiac involvement as presenting feature, three primary cardiomyopathy, three secondary to PAH. Two patients died after a brief disease course and one rapidly underwent heart transplantation. In comparison with cJSSc, ssJSSc showed a significantly longer diagnostic delay (20.1 vs 8.3 months, P = 0.017), higher frequency of cardiac involvement (85.7 vs 15.6%, P = 0.001) and worse outcome, intended as mortality or end-stage organ failure rates (42.9% vs 6.2%, P &lt; 0.001).

Conclusion
Cardiac involvement represents the most important characteristic of ssJSSc and carries a high morbidity and mortality rate. The longer delay in diagnosis underlines the need for a comprehensive rheumatological work-up in patients with isolated cardiomyopathy or PAH/ILD.

Abstract

Objective
Negative symptoms and cognitive impairment in schizophrenia (SZ) remain unmet treatment needs as they are highly prevalent, associated with poor functional outcomes, and resistant to pharmacologic treatment. The current pilot randomized controlled trial examined the efficacy of an integrated Cognitive-Behavioral Social Skills Training and Compensatory Cognitive Training (CBSST-CCT) intervention compared to Goal-focused Supportive Contact (SC) on negative symptoms and cognitive performance.

Methods
Fifty-five adults with SZ or schizoaffective disorder with moderate-to-severe negative symptoms were randomized to receive 25 twice-weekly, 1-h manualized group sessions (12.5 weeks total duration) of either CBSST-CCT or SC delivered by master’s level clinicians in five community settings. Assessments of negative symptom severity (primary outcomes) and neuropsychological performance, functional capacity, social skills performance, and self-reported functional ability/everyday functioning, psychiatric symptom severity, and motivation (secondary outcomes) were administered at baseline, mid-treatment, post-treatment, and 6-month follow-up.

Results
Mixed-effects models using baseline, mid-treatment, and post-treatment data demonstrated significant CBSST-CCT-associated effects on negative symptom severity, as assessed by the Scale for the Assessment of Negative Symptoms (p = .049, r = 0.22), with improvements in diminished motivation driving this effect (p = .037, r = 0.24). The CBSST-CCT group also demonstrated improved verbal learning compared to SC participants (p = .026, r = 0.36). The effects of CBSST-CCT appeared to be durable at 6-month follow-up.

Conclusions
CBSST-CCT improved negative symptom severity and verbal learning in high-negative-symptom individuals relative to SC. CBSST-CCT warrants larger investigations to examine its efficacy in treating negative symptoms, along with other symptoms, cognition, and, ultimately, real-world functional outcomes. Clinical Trial registration number NCT02170051.
Protective State Policies and the Employment of Fathers with Criminal Records
Authors: Dwyer Emory Allison 
Published: September 2021

Abstract
A criminal record can be a serious impediment to securing stable employment, with negative implications for the economic stability of individuals and their families. State policies intended to address this issue have had mixed results, however. Using panel data from the Fragile Families study merged with longitudinal data on state-level policies, this study investigates the association between criminal record based employment discrimination policies and the employment of men both with and without criminal records. These state policies broadly regulate what kinds of records can be legally used for hiring and licensing decisions, but have received little attention in prior research. Findings indicate that men with criminal records were less likely to be working if they lived in states with more policies in place to regulate the legal use of those records. Consistent with research linking policies regulating access to records to racial discrimination, black men living in protective states reported this employment penalty even if they did not have criminal records themselves. Thus, these policies, at best, may fail to disrupt entrenched employment disparities and, at worst, may exacerbate racial discrimination.
Divergent Processes Drive Parallel Evolution in Marine and Freshwater Fishes

Abstract
Evolutionary comparisons between major environmental divides, such as between marine and freshwater systems, can reveal the fundamental processes governing diversification dynamics. Although processes may differ due to the different scales of their biogeographic barriers, freshwater and marine environments nevertheless offer similar opportunities for diversification in benthic, demersal, and pelagic habitats. Here, we compare the evolutionary patterns and processes shaping teleost diversity in each of these three habitats and between marine and freshwater systems. Using specimens from the National Museum of Natural History, we developed a data set of linear measurements capturing body shape in 2266 freshwater and 3344 marine teleost species. With a novel comparative approach, we contrast the primary axis of morphological diversification in each habitat with the major axis defined by phylogenetic signal. By comparing angles between these axes, we find that fish in corresponding habitats have more similar primary axes of morphological diversity than would be expected by chance, but that different historical processes underlie these parallel patterns in freshwater and marine environments. Marine diversification is more strongly aligned with phylogenetic signal and shows a trend toward lineages occupying separate regions of morphospace. In contrast, ecological signal appears to be a strong driver of diversification in freshwater lineages through repeated morphological evolution in densely packed regions of morphospace. In spite of these divergent histories, our findings reveal that habitat has driven convergent patterns of evolutionary diversification on a global scale.

AbstractSilver nanoparticles, “AgNPs”, represent a prominent nanoproduct, but most of the previous toxicity studies on its genotoxicity are still limited. The current study aimed to assess the genotoxicity of AgNPs on lymphocyte cells using comet assay and to study the recovery probability. It was conducted on 50 adult male albino rats divided into “Control group”, 10 rats were injected intraperitoneal, “IP”, with distilled water for 28 days, and “Test groups”, 40 rats were injected “IP” with 13 ± 3 nm AgNPs for 28 days, subdivided into group I: 10 rats were injected with 2 mg/kg AgNPs, group Ia: 10 rats were injected with 2 mg/kg AgNPs and left for another 4 weeks without scarification, group II: 10 rats were injected with 4 mg/kg AgNPs, and group IIa: 10 rats were injected with 4 mg/kg and left for another 4 weeks without scarification. There was a highly significant decrease in head parameters with an increase in tail parameters in both groups I and II and in group II more than group I. Moreover, there was a highly significant increase in head parameters with a decrease in tail parameters in group Ia compared with the control group and group IIa. Comets were classified according to the tail intensity and according to visual scoring for DNA damage, which revealed different grades of DNA damage with a degree of reversibility after 4 weeks stoppage of exposure. It could be concluded that AgNPs were considered to cause harmful genotoxic effects to the human body in a dose-dependent manner.

Abstract
The key molecular mechanisms underlying the sectionalized growth within bamboo or other grass internodes remain largely unknown. Here, we genetically and morphologically compared the culm and rhizome internode division zones (DZs) of a slow-growing bamboo variant (sgv) having dwarf internodes, with those of the corresponding wild type (WT). Histological analysis discovers that the sgv has an irregular internode DZ. However, the shoot apical meristems in height, width, outside shape, cell number and cell width of the sgv and the WT were all similar. The DZ irregularities first appeared post apical meristem development, in 1-mm sgv rhizome internodes. Thus, the sgv is a DZ irregularity bamboo variant, which has been first reported in bamboo according to our investigation. Transcriptome sequencing analysis finds that a number of cell wall biogenesis and cell division-related genes are dramatically downregulated in the sgv DZ. Interestingly, both transcriptomic and brassinosteroid (BR) contents detection, as well as quantitative real-time PCR analyses show that these irregularities have resulted from the BR signaling pathway defects. Brassinosteroid defect might also cause the erect leaves and branches as well as the irregular epidermis of the sgv. These results suggest that BR signaling pathway plays critical roles in bamboo internode DZ and leaf development from a mutant perspective and also explain the upstream mechanisms causing the dwarf internode of the sgv bamboo.

Abstract

Background
Coronavirus disease 2019 (COVID-19) has resulted in a huge burden on healthcare systems, especially on programs for chronic illnesses such as HIV. We aimed to assess the challenges confronting adult people living with HIV (PLHIV) in three countries in North Africa during the COVID-19 crisis and their awareness of COVID-19 non-pharmaceutical preventive measures.

Methods
This online survey included PLHIV aged ≥18 y from three countries in North Africa recruited by a snowball sampling technique, who were asked to complete a modified questionnaire originally developed by the University of Antwerp in Belgium, which was then disseminated through social media tools to assess the study outcomes.

Results
Out of 369 respondents, 260 (70.5%) were males and 237 (64.2%) were aged 18–39 y. Adherence to COVID-19 preventive measures, wearing facemasks (308 [83.2%]), applying hand-sanitizers (299 [80.8%]) and following cough etiquette (261 [70.5%]), were predominantly reported. Only 48 (13%) were vaccinated against influenza. One hundred and forty-five participants (42%) experienced flu-like symptoms, 29 (20%) were tested for COVID-19, with only one confirmed case identified. Among 344 (93.2%) on antiretroviral therapy (73.8% efavirenz- vs 6.4% dolutegravir-based regimens), 219 (63.7%) attended their scheduled visits, 144 (41.9%) had limited access to care due to lockdown and 29 (8.4%) became less adherent to their antiretroviral therapy. Covariates associated with challenges during access to care were age ≥60 y (OR=6.5; 95% CI 1.8 to 23.2) and receiving second-line HIV treatment such as protease inhibitors (OR=2.7; 95% CI 1.3 to 5.8).

Conclusion
The pandemic adversely affected PLHIV. New innovative strategies should be implemented to ensure the continuity of HIV services.

Published: September 2021

ABSTRACT

Objectives:
This quality improvement initiative aimed to develop and implement a protocol for an alcohol and substance use disorder screening for primary care.

Methods:
The Two Item Conjoint Screen was selected and a process was piloted by care teams. Quality improvement tools were used to improve the protocol. Primary care providers (PCPs) were surveyed about their use of the screening protocol in the primary care setting. Data on total number of screenings were collected through the electronic health record.

Results:
Implementation resulted in more than 30,000 screenings completed in 2016. PCP survey results indicated that PCPs felt screening was helpful in identifying potential substance use problems (100%) and that most providers (76%) felt that overall patient care improved after screening was initiated.

Conclusions:
Brief alcohol and substance use disorder screenings can be easily implemented and well integrated into primary care settings. PCPs found screenings to be valuable in caring for patients.

Abstract
Most children with coronavirus disease 2019 (COVID-19) infection are asymptomatic or have mild disease. About 5% of infected children will develop severe or critical disease. Rapid identification and treatment are essential for children who are critically ill with signs and symptoms of respiratory failure, septic shock, and multisystem inflammatory syndrome in children. This article is intended for pediatricians, pediatric emergency physicians, and individuals involved in the emergency care of children. It reviews the current epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children, summarizes key aspects of clinical assessment including identification of high-risk patients and manifestations of severe disease, and provides an overview of COVID-19 management in the emergency department based on clinical severity.
Standardized incidence ratio of the COVID-19 pandemic: a case study in a Midwestern state
Authors: Spors Emma , Michael Semhar 
Published: September 2021

ABSTRACTMotivationThe Coronavirus disease 2019 (COVID-19) has made a dramatic impact around the world, with some communities facing harsher outcomes than others. We sought to understand how counties in the state of South Dakota (SD) fared compared to expected based on a reference population and what factors contributed to negative outcomes from the pandemic in SD.MethodsThe Standardized Incidence Ratios (SIR) of all counties, using age-adjusted and crude adjusted hospitalization and death rates were computed using the SD age-adjusted rate as a reference population. In addition, a penalized generalized linear regression model was used to identify factors that are associated with COVID-19 hospitalization and death rates. This model was then used to compute a new SIR after controlling for other socio-demographic and -economic factors.ResultsWe identified counties that had more or less severe outcomes than what would be expected based on the rate of SD after age adjustment. Additionally, race, education, and testing rate were some of the significant factors associated with the outcome. The SIR values after controlling for these additional factors showed change in magnitude from the range of 4 times more severe to 1.5 times more severe out-come than what is expected. Interestingly the lower end of this interval did not have a major change.ConclusionThe age adjusted SIR model used in this study allowed for the identification of counties with more or less severe than what is expected based on the state rate. These counties tended to be those with high nonwhite percentage, which mostly included counties with American Indian reservations. Although several predictors are associated with hospitalization and deaths, the penalized model confirmed what is already reported in literature that race and education level have a very high association with the outcome variables. As can be expected the further adjusted SIR mostly changed in those counties with higher than expected outcomes. We believe that these results may provide useful information to improve the implementation of mitigation strategies to curb the damage of this or future pandemics by providing a way for data-driven resource allocation.

AbstractHeart rate variability is a robust biomarker of emotional well-being, consistent with the shared brain networks regulating emotion regulation and heart rate. While high heart rate oscillatory activity clearly indicates healthy regulatory brain systems, can increasing this oscillatory activity also affect brain function? To test this possibility, we randomly assigned 106 young adult participants to one of two 5-week interventions involving daily biofeedback that either increased heart rate oscillations (Osc+ condition) or had little effect on heart rate oscillations (Osc- condition) and examined effects on brain activity during rest and during regulating emotion. While there were no significant changes in the right amygdala-medial prefrontal cortex (MPFC) functional connectivity (our primary outcome), the Osc+ intervention increased left amygdala-MPFC functional connectivity and functional connectivity in emotion-related resting-state networks during rest. It also increased down-regulation of activity in somatosensory brain regions during an emotion regulation task. The Osc- intervention did not have these effects. In this healthy cohort, the two conditions did not differentially affect anxiety, depression or mood. These findings indicate that heart rate oscillatory activity not only provides a measure of the current state of regulatory brain systems but also changes emotion network coordination in the brain.Significance StatementPeople whose breathing makes their heart rate oscillate more (leading to higher heart rate variability or HRV) generally have better regulated emotion. Thus, HRV may indicate functioning of brain networks regulating emotion and internal body states. But heart rate oscillations may not only reflect brain regulatory networks but also help shape these networks. We randomly assigned participants to practice either increasing heart rate oscillations using slow-paced breathing or decreasing them using personalized strategies. Daily practice increasing heart rate oscillations affected brain activity in emotion-related networks even during times when participants breathed no differently than the comparison group. Thus, HRV is more than just an outcome measure--it can help shape the subsequent functioning of emotion-related brain networks.
