Neural Tube Defects in Pregnancies Among Women With Diagnosed HIV Infection - 15 Jurisdictions, 2013-2017

Dolutegravir and pregnancy outcomes including neural tube defects in the USA during 2008-20: a national cohort study

BACKGROUND

A study from Botswana identified an increased risk of neural tube defects (NTDs) in infants of mothers with HIV who were treated with dolutegravir around the time of conception. We aimed to examine associations of dolutegravir use with NTDs and pregnancy loss using large health-care claims databases from the USA, a country with folic acid fortification of food.

METHODS

In this cohort study, we analysed health-care claims data, recorded in the Merative MarketScan commercial database (MarketScan data) and Centers for Medicare & Medicaid Services Medicaid database (Medicaid data) from Jan 1, 2008, to Dec 31, 2020. We identified pregnancies with enrolment during their entire duration among women aged 15-49 years and we estimated time of conception. For each pregnancy, we determined HIV status and periconceptional exposure to dolutegravir or other antiretroviral agents. We estimated and compared the incidence rate of NTDs, stillbirths, and pregnancy loss (ie, spontaneous or induced abortions) by type of periconceptional antiretroviral exposure. We calculated adjusted risk ratios of the adverse outcomes using Poisson models adjusting for demographic and clinical factors.

FINDINGS

Of 4 489 315 pregnancies in MarketScan data and 14 405 861 pregnancies in Medicaid data that had full enrolment, we identified 69 pregnancies in MarketScan data and 993 pregnancies in Medicaid data that were associated with HIV and periconceptional dolutegravir exposure. For women without HIV, the NTD rate was 4·1 per 10 000 live births (95% CI 3·9-4·3) in MarketScan and 5·7 per 10 000 live births (5·6-5·8) in Medicaid. No NTD cases were found among those with dolutegravir or non- dolutegravir antiretroviral drug exposure in the MarketScan data; only one NTD case was identified among women with dolutegravir, and three among women with non-dolutegravir antiretroviral exposure in Medicaid. After adjusting for covariates, there were no significant differences in risk ratios of NTD between groups with periconceptional dolutegravir or non-dolutegravir antiretroviral exposure and the group without HIV. However, compared with women without HIV, the risk of pregnancy loss was higher among women exposed to antiretroviral therapy: for dolutegravir exposure the adjusted risk ratio was 1·73 (95% CI 1·20-2·49) in MarketScan data and 1·41 (1·30-1·54) in Medicaid data; for non-dolutegravir antiretroviral exposure the adjusted risk ratio was 1·23 (1·10-1·37) in MarketScan data and 1·11 (1·07-1·15) in Medicaid data.

INTERPRETATION

We studied the largest US cohort of women with periconceptional or early-pregnancy dolutegravir exposure. Our results do not show an increased risk of NTDs in exposed infants in the USA. Administrative databases can be used, with rigorous methodology, to study correlates of rare outcomes, such as NTDs, and to monitor for adverse pregnancy outcomes in women who receive antiretrovirals.

Fresh Washed Microbiota Transplantation Alters Gut Microbiota Metabolites to Ameliorate Sleeping Disorder Symptom of Autistic Children

Accumulating studies have raised concerns about gut dysbiosis associating autism spectrum disorder (ASD) and its related symptoms. However, the effect of gut microbiota modification on the Chinese ASD population and its underlying mechanism were still elusive. Herein, we enrolled 24 ASD children to perform the first course of fresh washed microbiota transplantation (WMT), 18 patients decided to participate the second course, 13 of which stayed to participate the third course, and there were 8 patients at the fourth course. Then we evaluated the effects of fresh WMT on these patients and their related symptoms. Our results found that the sleeping disorder symptom was positively interrelated to ASD, fresh WMT significantly alleviated ASD and its sleeping disorder and constipation symptoms. In addition, WMT stably and continuously downregulated Bacteroides/Flavonifractor/Parasutterella while upregulated Prevotella_9 to decrease toxic metabolic production and improve detoxification by regulating glycolysis/myo-inositol/D-glucuronide/D-glucarate degradation, L-1,2-propanediol degradation, fatty acid β-oxidation. Thus, our results suggested that fresh WMT moderated gut microbiome to improve the behavioral and sleeping disorder symptoms of ASD via decrease toxic metabolic production and improve detoxification. Which thus provides a promising gut ecological strategy for ASD children and its related symptoms treatments.

Burden of Neural Tube Defects and Their Associated Factors in Africa: A Systematic Review and Meta-Analysis

Background

Neural tube defects are a type of congenital anomaly caused by an abnormality in the development of the brain and spinal cord during embryogenesis. They cause high rates of mortality, morbidity, and lifelong disability. There are several studies carried out worldwide reporting different findings on the burden and associated factors. The aim of this study is to carry out a systematic review and meta-analysis of the burden of neural tube defects and their associated factors in Africa.

Methods

A total of 58 eligible articles were identified systematically using databases such as PubMed, Embase, African Journal Online Library, ProQuest, Cochrane, Google Scopus, Google Scholar, and Grey literature. Extracted data were analyzed using STATA 16.0 statistical software. The heterogeneity of studies was determined using the Cochrane Q test statistic and I² test statistics with forest plots. A random effects model was used to examine the pooled burden of neural tube defects, subgroups of the region, subtypes of NTDs, sensitivity analysis, and publication bias. The association between NTDs and associated factors was studied using a fixed-effect model.

Results

Fifty-eight studies with a total of 7,150,654 participants in 16 African countries revealed that the pooled burden of neural tube defects was 32.95 per 10,000 births (95% CI: 29.77-36.13). The Eastern African region had the highest burden in the subgroup analysis, with 111.13 per 10,000 births (95% CI: 91.85-130.42). South African countries had the lowest burden, at 11.43 per 10,000 births (95% CI: 7.51-15.34). In subtype analysis, spina bifida had the highest pooled burden at 17.01 per 10,000 births (95 percent CI: 15.00-19.00), while encephalocele had the lowest at 1.66 per 10,000 births (95% CI: 1.12-2.20). Maternal folic acid supplementation (AOR: 0.38; 95% CI: 0.16-0.94), alcohol consumption (AOR: 2.54; 95% CI: 1.08-5.96), maternal age (AOR: 3.54; 95% CI: 1.67-7.47), pesticide exposure (AOR: 2.69; 95% CI: 1.62-4.46), X-ray radiation (AOR: 2.67; 95% CI: 1.05-6.78), and history of stillbirth (AOR: 3.18; 95% CI: 1.11-9.12) were significantly associated with NTDs.

Conclusion

The pooled burden of NTDs in Africa was found to be high. Maternal age, alcohol consumption, pesticide and X-ray radiation exposure, history of stillbirth, and folic acid supplementation were significantly associated with NTDs.

Experiences, risk perceptions, and COVID-19 vaccination outcomes among hospital workers

BACKGROUND

Although COVID-19 vaccinations have been available to hospital workers in the U.S. since December 2020, coverage is far from universal, even in groups with patient contact. The aim of this study was to describe COVID-19-related experiences at work and in the personal lives of nurses, allied health workers, and non-clinical staff with patient contact, and to assess whether these experiences relate to COVID-19 vaccination.

METHODS

Health care workers at a large Midwestern hospital in the U.S. were contacted to participate in an online cross-sectional survey during February 2021. A logistic regression model was used to estimate odds ratios (OR) for vaccination by different experiences, and we assessed mediation through models that also included measures of risk perceptions.

RESULTS

Among 366 nurse practitioners / nurse midwives / physician assistant, 1,698 nurses, 1,798 allied health professionals, and 1,307 non-clinical staff with patient contact, the proportions who had received or intended to receive a COVID-19 vaccination were 94 %, 87 %, 82 %, and 88 %, respectively. Working and being physically close to COVID-19 patients was not significantly associated with vaccine intent. Vaccination intent was significantly lower among those with a previous COVID-19 diagnosis vs not (OR = 0.33, 95 % CI: 0.27, 0.40) and higher for those who knew close family members of friends hospitalized or died of COVID-19 (OR = 1.33, 95 % CI: 1.10, 1.60).

CONCLUSION

Even when COVID-19 vaccination was available in February 2021, a substantial minority of hospital workers with patient contact did not intend to be vaccinated. Moreover, their experiences working close to COVID-19 patients were not significantly related to vaccination intent. Instead, personal experiences with family members and friends were associated with vaccination intent through changes in risk perceptions. Interventions to increase uptake among hospital workers should emphasize protection of close family members or friends and the severity of COVID-19.

Can Primary Care Drive Tuberculosis Elimination? Increasing Latent Tuberculosis Infection Testing and Treatment Initiation at a Community Health Center with a Large Non-U.S.-born Population

Community health centers (CHC) play a key role in latent tuberculosis infection (LTBI) testing and treatment. We performed a retrospective analysis of LTBI testing and treatment among pediatric and adult patients at a CHC with a large non-U.S.-born (USB) population during a series of quality improvement (QI) interventions from 2010 to 2019. Among 124,695 patients with primary care visits, 40% of patients were tested for tuberculosis (TB) infection and among those tested, 20% tested positive, including 39% of adults aged 50-79 years. Compared to adults aged 18-49 years, children aged 6-17 had increased odds of LTBI testing and treatment initiation [odds ratio and 95% confidence interval 3.23 (3.10, 3.36) and 1.41 (1.12, 1.79), respectively], while age ≥ 65 was associated with lower odds of both testing and treatment initiation. Over the analysis period, coinciding with unfunded QI interventions intended to reduce barriers to LTBI care, there was a significant increase in the proportion of patients receiving LTBI testing for both adults (6% to 47%, p < 0.001) and children (23% to 80%, p < 0.001). During the analysis period, there was also a significant increase in the proportion of patients receiving prescriptions for LTBI treatment, as well as provider use of evidence-based strategies including rifamycin-based treatment. Our study suggests that primary care interventions can reduce barriers to LTBI treatment and drive TB elimination.

The Association Between Dating Violence and Student Absenteeism Among a Representative Sample of U.S. High School Students: Findings From the 2019 Youth Risk Behavior Survey Survey

Student absenteeism affects students' engagement in school and academic and professional success. While research documents a significant association between school bullying/fighting and student absenteeism due to fear of being at school or getting to school, little research has examined the association of adolescent dating violence (ADV) victimization with this type of absenteeism. This study examined the relationship between physical and/or sexual ADV victimization in the past year (dichotomized as yes or no), and number of days of student absenteeism due to feeling unsafe at school or on the way to school in the past month (dichotomized as any vs. none). We analyzed cross-sectional data from the 2019 Youth Risk Behavior Survey (YRBS), a nationally representative survey of U.S. high school students (n = 9507). We conducted crude and multivariate regression models for the total sample and stratified by sex to assess our hypothesized association of ADV victimization and absenteeism; sex, grade, race/ethnicity, and sexual identity were included as covariates in adjusted models. Findings demonstrate that students reporting past year ADV victimization had 3.69 times the odds of student absenteeism due to feeling unsafe, when compared to students who did not report ADV victimization (95% CI: 3.06-4.45, p < 0.001). Sex-stratified models reveal that this effect is significantly stronger for males than for females, as indicated by non-overlapping confidence intervals (male AOR: 5.67, 95% CI: 4.18-7.68; female AOR: 2.95, 95% CI: 2.32-3.74). The multivariate models also show that Black and Latinx compared with White students, and lesbian/gay/bisexual/unsure compared with heterosexual students, had higher odds of student absenteeism due to feeling unsafe. Findings indicate the need to address ADV victimization and student absenteeism with integrated and gender-tailored responses, and with consideration of greater vulnerabilities for queer students and students of color.

An SBQ-R assessment of the impact of COVID-19 pandemic on the mental health of young adults in North India

BACKGROUND AND AIM

During the COVID-19 pandemic in India, an increase in the number of suicides was observed in India. Therefore, the present study aims to explore various factors affecting the mental health of an individual and their consequences. Moreover, it has been attempted to assess the suicidal risk in the population of North India by using the Suicidal Behaviors Questionnaire-Revised (SBQ-R).

METHODOLOGY

The young adults from the North Indian population belonging to the age group of 18 to 35 years (24.93±4.42 years) have been incorporated into the study. A total of 190 responses (102 males and 88 females) were recorded through online mode. The present questionnaire has incorporated the Suicidal Behaviors Questionnaire-Revised (SBQ-R) and some of the parameters taken from the psychology today online survey.

RESULTS

The demographic characteristics of the respondents were described by using frequencies and percentages, means, and standard deviations. Cronbach's alpha, Kaiser-Meyer-Olkin (KMO), and the Bartlett sphericity were calculated. The mean SBQ-R score was recorded to be 4.62±1.5. Further, during the factor analysis with the principal component method, seven factors have explained the 70.797% of the cumulative variance with an eigenvalue of 1.

CONCLUSIONS

The SBQ-R assessment revealed a minimal risk of suicidal behavior but the frequency distribution of the parameters taken for the psychological assessment has highlighted that anxiousness or worriedness has a significant impact on the mental health of the population at risk. Therefore, it is recommended that some precautionary measures, such as online mental health services, should be taken by the health ministry to keep the population healthy.

The effects of opioid policy changes on transitions from prescription opioids to heroin, fentanyl and injection drug use: a qualitative analysis

BACKGROUND

Beginning in the 1990s, nonmedical use of prescription opioids (POs) became a major public health crisis. In response to rising rates of opioid dependence and fatal poisonings, measures were instituted to decrease the prescription, diversion, and nonmedical use of POs including prescription drug monitoring programs (PDMPs), pain clinic laws, prescription duration limits, disciplining doctors who prescribed an excessive number of POs, and the advent of abuse deterrent formulations of POs. This paper explores the unintended effects of these policies in the descriptions of why people who use opioids transitioned from PO to injection or heroin/fentanyl use.

METHODS

We conducted 148 in-depth-interviews with people who use prescription opioids nonmedically, fentanyl or heroin from a rural, urban and suburban area in three states, Connecticut, Kentucky and Wisconsin. Interviews with people who use opioids (PWUO) focused on how they initiated their opioid use and any transitions they made from PO use to heroin, fentanyl or injection drug use.

RESULTS

The majority of participants reported initiating use with POs, which they used for medical or nonmedical purposes. They described needing to take more POs or switched to heroin or fentanyl as their tolerance increased. As more policies were passed to limit opioid prescribing, participants noticed that doctors were less likely to prescribe or refill POs. This led to scarcity of POs on the street which accelerated the switch to heroin or fentanyl. These transitions likely increased risk of overdose and HIV/HCV infection.

CONCLUSIONS

A careful analysis of how and why people say they transitioned from PO to heroin or fentanyl reveals many unintended harms of policy changes to prevent overprescribing and diversion. Results highlight the importance of mitigating harms that resulted from policy changes.

Birth prevalence of neural tube defects in eastern Africa: a systematic review and meta-analysis

BACKGROUND

Neural tube defects (NTDs) are associated with high rates of neonatal mortality and morbidity worldwide. The promotion of folic acid fortification and supplementation in pregnant women by the Food and Drug Administration significantly decreased the incidence of NTDs in the United States. This practice is not widely adopted in Eastern Africa countries. We hypothesized that these countries experience a higher burden of NTDs than countries that promote the use of folic acid. We aimed to estimate the birth prevalence of NTDs in the United Nations (UN) Eastern African region.

METHODS

PubMed (Medline), Embase, and Cochrane Library databases were systematically searched from inception to December 17, 2021. We included randomized controlled trials or observational studies that reported the prevalence estimates of NTDs in Eastern Africa. Random effects model was used to pool the effect estimates. The GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach was used to assess the certainty of the evidence. Outcome measures were overall and specific (spina bifida, anencephaly, encephalocele) rates of NTDs per 10,000 births, including live and stillborn cases.

RESULTS

The meta-analysis included 20 studies consisting of 752,936 individuals. The pooled prevalence of all NTDs per 10,000 births in Eastern Africa was 33.30 (95% CI: 21.58 to 51.34). Between-study heterogeneity was high (I² = 97%, p < 0.0001), The rate was highest in Ethiopia (60 per 10,000). Birth prevalence of spina bifida (20 per 10,000) was higher than anencephaly (9 per 10,000) and encephalocele (2.33 per 10,000). No studies on NTDs were identified in 70% of the UN Eastern Africa region. Birth prevalence increased by 4% per year from 1983 to 2018. The level of evidence as qualified with GRADE was moderate.

CONCLUSION

The birth prevalence of NTDs in the United Nations region of Eastern Africa is 5 times as high as observed in Western countries with mandatory folic acid supplementation in place. Therefore, mandatory folic acid supplementation of stable foods may decrease the risk of NTDs in Eastern Africa.

The role of risk perception and affective response in the COVID-19 preventive behaviours of young adults: a mixed methods study of university students in the Netherlands

OBJECTIVES

Due to an increased infection rate among young adults, they need to adhere to the preventive guidelines to stop the spread of COVID-19 and protect vulnerable others. The purpose of this mixed methods study was to explore the role of risk perception and affective response in the preventive behaviours of young adults during the COVID-19 outbreak.

SETTING

This study followed a convergent mixed methods design, in which a quantitative online survey (n=1081) and 10 qualitative in-depth semistructured video interviews were conducted separately in the Netherlands during April-August 2020.

PARTICIPANTS

1081 participants filled in the online survey, and 10 participants participated in the interviews. Eligibility criteria included being a university student.

PRIMARY AND SECONDARY OUTCOME MEASURES

Data on risk perception, affective response, that is, worry, and adherence to preventive guidelines were combined and analysed during this study. There were no secondary outcome measures.

RESULTS

The results showed that young adults perceived their risk as low. Their affective response for their own well-being was also low; however, their affective response was high with regards to vulnerable others in their surroundings. Due to their high impersonal risk perception (ie, perceived risk to others) and high affective response, young adults adhered to most preventive guidelines relatively frequently. However, young adults sometimes neglected social distancing due to the negative effects on mental health and the uncertainty of the duration of the situation.

CONCLUSIONS

In conclusion, high impersonal risk perception and high affective response regarding others are key motivators in young adults' preventive behaviour. To maximise adherence to the preventive guidelines, risk communication should put emphasis on the benefits to vulnerable others' health when young adults adhere to the preventive guidelines.

Suicide Attempts Among Racial and Ethnic Groups in a Nationally Representative Sample

OBJECTIVE

Evaluate suicide attempt prevalence and potentially related sociodemographic and psychiatric factors among racial and ethnic groups.

METHODS

Between 2012 and 2013, the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) conducted semi-structured interviews with 36,309 adults in the USA. We identified lifetime suicide attempt prevalence and significant predictors for each racial/ethnic group using stratified logistic regressions. Analyses were exploratory without a priori hypotheses.

RESULTS

Asian/Native Hawaiian/other Pacific Islander and Black individuals had the lowest prevalence of suicide attempts while Alaska Native/American Indian and White individuals had the highest prevalence. Identifying as female and meeting criteria for psychiatric diagnoses featuring mood regulation difficulties (depression, borderline personality disorder, bipolar I disorder) were consistently related to a suicide attempt history across racial and ethnic groups, whereas substance abuse disorders and other sociodemographic factors differed between racial and ethnic groups in their associations with suicide attempt history.

CONCLUSIONS

Although several factors were consistently related to suicide risk across racial and ethnic groups, the prevalence of suicide attempts and overall pattern of related factors were not uniform between racial and ethnic groups.

POLICY IMPLICATIONS

Study findings highlight the importance of considering suicide risk within the context of race and ethnicity both regarding the overall prevalence of risk and in determining personal factors associated with elevated risk. A failure to appreciate experiences related to race and ethnicity may adversely impact suicide risk assessment and treatment, ultimately contributing to health disparities. Results suggest that additional research is warranted.

Meningococcal Disease Outbreaks: A Moving Target and a Case for Routine Preventative Vaccination

Outbreaks of invasive meningococcal disease (IMD) are unpredictable, can be sudden and have devastating consequences. We conducted a non-systematic review of the literature in PubMed (1997-2020) to assess outbreak response strategies and the impact of vaccine interventions. Since 1997, IMD outbreaks due to serogroups A, B, C, W, Y and X have occurred globally. Reactive emergency mass vaccination campaigns have encompassed single institutions (schools, universities) through to whole sections of the population at regional/national levels (e.g. serogroup B outbreaks in Saguenay-Lac-Saint-Jean region, Canada and New Zealand). Emergency vaccination responses to IMD outbreaks consistently incurred substantial costs (expenditure on vaccine supplies, personnel costs and interruption of other programmes). Impediments included the limited pace of transmission of information to parents/communities/healthcare workers; issues around collection of informed consents; poor vaccine uptake by older adolescents/young adults, often a target age group; issues of reimbursement, particularly in the USA; and difficulties in swift supply of large quantities of vaccines. For serogroup B outbreaks, the need for two doses was a significant issue that contributed substantially to costs, delayed onset of protection and non-compliance with dose 2. Real-world descriptions of outbreak control strategies and the associated challenges systematically show that reactive outbreak management is administratively, logistically and financially costly, and that its impact can be difficult to measure. In view of the unpredictability, fast pace and potential lethality of outbreak-associated IMD, prevention through routine vaccination appears the most effective mitigation tool. Highly effective vaccines covering five of six disease-causing serogroups are available. Preparedness through routine vaccination programmes will enhance the speed and effectiveness of outbreak responses, should they be needed (ready access to vaccines and need for a single booster dose rather than a primary series).

Characterizing HIV-1 Genetic Subtypes and Drug Resistance Mutations among Children, Adolescents and Pregnant Women in Sierra Leone

Human immunodeficiency virus (HIV) drug resistance (HIVDR) is widespread in sub-Saharan Africa. Children and pregnant women are particularly vulnerable, and laboratory testing capacity remains limited. We, therefore, used a cross-sectional design and convenience sampling to characterize HIV subtypes and resistance-associated mutations (RAMs) in these groups in Sierra Leone. In total, 96 children (age 2–9 years, 100% ART-experienced), 47 adolescents (age 10–18 years, 100% ART-experienced), and 54 pregnant women (>18 years, 72% ART-experienced) were enrolled. Median treatment durations were 36, 84, and 3 months, respectively, while the sequencing success rates were 45%, 70%, and 59%, respectively, among children, adolescents, and pregnant women. Overall, the predominant HIV-1 subtype was CRF02_AG (87.9%, 95/108), with minority variants constituting 12%. Among children and adolescents, the most common RAMs were M184V (76.6%, n = 49/64), K103N (45.3%, n = 29/64), Y181C/V/I (28.1%, n = 18/64), T215F/Y (25.0%, n = 16/64), and V108I (18.8%, n = 12/64). Among pregnant women, the most frequent RAMs were K103N (20.6%, n = 7/34), M184V (11.8%, n = 4/34), Y181C/V/I (5.9%, n = 2/34), P225H (8.8%, n = 3/34), and K219N/E/Q/R (5.9%, n = 2/34). Protease and integrase inhibitor-RAMs were relatively few or absent. Based on the genotype susceptibility score distributions, 73%, 88%, and 14% of children, adolescents, and pregnant women, respectively, were not susceptible to all three drug components of the WHO preferred first-line regimens per 2018 guidelines. These findings suggest that routine HIVDR surveillance and access to better ART choices may improve treatment outcomes in Sierra Leone.

Latent tuberculosis infection: Misperceptions among non-U.S.-born-populations from countries where tuberculosis is common

ABSTRACTThe Centers for Disease Control and Prevention works to eliminate tuberculosis (TB) disease by finding and treating cases of TB disease and expanding latent tuberculosis infection (LTBI) testing and treatment to prevent TB disease. Approximately 70% of reported TB cases in the United States occur among non-U.S.-born persons. We conducted 15 focus groups with U.S. residents born in the six most common countries of birth among non-U.S.-born TB patients: Mexico, the Philippines, India, Vietnam, China and Guatemala. Participants reacted to 39 messages on LTBI and TB disease risk factors, the Bacille Calmette-Guérin (BCG) vaccine, and LTBI testing and treatment. There was low awareness of LTBI, the TB blood test, and how the TB blood test is not affected by prior BCG vaccination. Several participants thought TB disease is contracted by sharing kitchenware. Some felt negatively targeted when presented with information about countries where TB disease is more common than the U.S. Findings highlight the need for communication aimed at increasing LTBI testing and treatment to include messages framed in ways that will be resonant and actionable to populations at risk. Focus groups revealed LTBI misconceptions which highlight areas for targeted education to decrease TB stigma and increase LTBI testing and treatment.

Immunogenicity and safety of an investigational quadrivalent meningococcal conjugate vaccine administered as a booster dose in children vaccinated against meningococcal disease 3 years earlier as toddlers: A Phase III, open-label, multi-center study

Booster doses of meningococcal conjugate vaccines induce long-term protection against invasive meningococcal disease. We evaluated the immunogenicity and safety of a booster dose of MenACYW-TT in pre-school children who were primed 3 years earlier with MenACYW-TT or MCV4-TT (Nimenrix®). In this Phase III, open-label, multi-center study (NCT03476135), children (4–5 years old), who received a primary dose of MenACYW-TT or MCV4-TT as toddlers in a previous study, received a booster dose of MenACYW-TT. Titers of antibody against meningococcal serogroups A, C, W and Y were measured by serum bactericidal assay using human (hSBA) and baby rabbit (rSBA) complement in samples collected before (D0) and 30 days after (D30) booster vaccination. Safety was assessed over the 30-day study period. Ninety-one participants received the booster dose. In both study groups, hSBA titers increased from D0 to D30; serogroup C titers [95% confidence interval] were higher in the MenACYW-TT-primed vs MCV4-TT-primed group at D0 (106 [73.2, 153] vs 11.7 [7.03, 19.4], respectively) and D30 (5894 [4325, 8031] vs 1592 [1165, 2174], respectively); rSBA results were similar. Nearly all participants achieved ≥1:8 hSBA and rSBA titers at D30, which were higher or comparable to those observed post-primary dose, suggesting rapid booster responses. At D0, all hSBA and rSBA titers were higher than those observed pre-primary dose, suggesting persistence of immunogenicity. The MenACYW-TT booster dose was well-tolerated and had similar safety outcomes across study groups. These findings suggest that MenACYW-TT elicits robust booster responses in children primed 3 years earlier with MenACYW-TT or MCV4-TT.

Mechanistic insights into antiretroviral drug-induced liver injury

All classes of antiretroviral therapy (ART) have been implicated to induce adverse drug reactions such drug-induced liver injury (DILI) and immune-mediated adverse reactions in Human Immunodeficiency Virus (HIV) infected individuals. Patients that develop adverse drug reactions tend to have prolonged stays in hospital and may require to change to alternative regimens if reactions persist upon rechallenge or if rechallenge is contraindicated due to severity of the adverse reaction. Diagnosis of DILI remains a huge obstacle that delays timely interventions, since it is still based largely on exclusion of other causes. There is an urgent need to develop robust diagnostic and predictive biomarkers that could be used alongside the available tools (biopsy, imaging, and serological tests for liver enzymes) to give a specific diagnosis of DILI. Crucial to this is also achieving consensus in the definition of DILI so that robust studies can be undertaken. Importantly, it is crucial that we gain deeper insights into the mechanism of DILI so that patients can receive appropriate management. In general, it has been demonstrated that the mechanism of ART-induced liver injury is driven by four main mechanisms: mitochondrial toxicity, metabolic host-mediated injury, immune reconstitution, and hypersensitivity reactions. The focus of this review is to discuss the type and phenotypes of DILI that are caused by the first line ART regimens. Furthermore, we will summarize recent studies that have elucidated the cellular and molecular mechanisms of DILI both in vivo and in vitro.

Unmet health care needs and health care quality in youth with autism spectrum disorder with and without intellectual disability

LAY ABSTRACT

The increase in the prevalence of autism spectrum disorder has placed greater demands on the health care system. Children and adolescents with autism spectrum disorder often experience challenges accessing high-quality physical and mental health care due to characteristic social-communication deficits and behavioral difficulties, as well as high rates of complex medical and psychiatric comorbidities. Intellectual disability commonly co-occurs with autism spectrum disorder and individuals affected by this co-occurrence may have additional impairments that compound challenges accessing health care. This study investigated the relations among co-occurring intellectual disability, unmet physical and mental health care needs, and health care quality in a large, nationally distributed sample of youth with autism spectrum disorder using structural equation modeling techniques. Co-occurring intellectual disability was significantly associated with unmet mental health care needs in children with autism. In addition, unmet mental health care needs mediated the relationship between co-occurring intellectual disability and health care quality; youth with autism spectrum disorder and co-occurring intellectual disability who had a past-year unmet mental health need had significantly poorer caregiver-reported health care quality. These findings suggest that youth with autism spectrum disorder and co-occurring intellectual disability may be more likely to experience unmet mental health care needs and receive poorer quality of care than the broader autism spectrum disorder population.

A systematic review and meta-analysis of obesity and COVID-19 outcomes

Some studies report that obesity is associated with more severe symptoms following SARS-CoV-2 infection and worse COVID-19 outcomes, however many other studies have not reproduced these findings. Therefore, it is uncertain whether obesity is in fact associated with worse COVID-19 outcomes compared to non-obese individuals. We conducted a systematic search of PubMed (including MEDLINE) and Google Scholar on May 18, 2020 to identify published studies on COVID-19 outcomes in non-obese and obese patients, covering studies published during the first 6 months of the pandemic. Meta-analyses with random effects modeling was used to determine unadjusted odds ratios (OR) and 95% confidence intervals (CI) for various COVID-19 outcomes in obese versus non-obese patients. By quantitative analyses of 22 studies from 7 countries in North America, Europe, and Asia, we found that obesity is associated with an increased likelihood of presenting with more severe COVID-19 symptoms (OR 3.03, 95% CI 1.45-6.28, P = 0.003; 4 studies, n = 974), developing acute respiratory distress syndrome (ARDS; OR 2.89, 95% CI 1.14-7.34, P = 0.025; 2 studies, n = 96), requiring hospitalization (OR 1.68, 95% CI 1.14-1.59, P < 0.001; 4 studies, n = 6611), being admitted to an intensive care unit (ICU; OR 1.35, 95% CI 1.15-1.65, P = 0.001; 9 studies, n = 5298), and undergoing invasive mechanical ventilation (IMV; OR 1.76, 95% CI 1.29-2.40, P < 0.001; 7 studies, n = 1558) compared to non-obese patients. However, obese patients had similar likelihoods of death from COVID-19 as non-obese patients (OR 0.96, 95% CI 0.74-1.25, P = 0.750; 9 studies, n = 20,597). Collectively, these data from the first 6 months of the pandemic suggested that obesity is associated with a more severe COVID-19 disease course but may not be associated with increased mortality.

Effects of Implementation and Enforcement Differences in Prescription Drug Monitoring Programs in 3 States: Connecticut, Kentucky, and Wisconsin

Background and aims:

Prescription Drug Monitoring Programs (PDMPs) were designed to curb opioid misuse and diversion by tracking scheduled medications prescribed by medical providers and dispensed by pharmacies. The effects of PDMPs on opioid prescription, misuse and overdose rates have been mixed due in part to variability in states’ PDMPs and difficulties measuring this complexity, and a lack of attention to implementation and enforcement of PDMP components. The current study uses qualitative interviews with key informants from 3 states with different PDMPs, Connecticut, Kentucky and Wisconsin to explore differences in the characteristics of the PDMPs in each state; how they are implemented, monitored and enforced; and unintended negative consequences of these programs.

Methods:

We conducted in-depth interviews with key informants from each state representing the following sectors: PDMP and pain clinic regulation agencies, Medicaid programs, state licensing boards, pharmacies, emergency medicine departments, pain management clinics, first responders, drug courts, drug treatment programs, medication assisted treatment (MAT) providers, and harm reduction organizations. Interview guides explored participants’ experiences with and opinions of PDMPs according to their roles. Data analysis was conducted using a collaborative, constant comparison method.

Results:

While all 3 states had mandated registration and reporting requirements, the states differed in the implementation and enforcement of these and the extent to which provider prescribing was monitored. These, in turn, influenced how medical providers perceived the PDMP and changed how providers prescribed opioids. Unintended consequences of state PDMPs included under-prescribing for pain and “dumping” patients who were long term users of opioids or who had developed opioid use disorders and may explain the increase in illicit heroin or opioid use.

Conclusion:

State PDMPs with similar mandates may differ greatly in implementation and enforcement. These differences are important to consider when determining the effects of PDMPs on opioid misuse and overdose.

Clinical and laboratory characteristics of SARS-CoV2-infected paediatric patients in Jordan: serial RT-PCR testing until discharge

BACKGROUND

Data on COVID-19 in children are limited. This study aimed to identify the clinical characteristics, laboratory results and longitudinal RT-PCR- testing pattern in children infected with theSARS-CoV2 virus and admitted to a hospital in Jordan.

METHODS

The study is a retrospective chart review of patients admitted between 16 March and 23 April 2020. All infected children in Jordan were hospitalised. Serial RT-PCR testing was undertaken 7 days after the first test and then on alternate days until discharge. The association between patient symptoms and laboratory results and whether there was a statistically significant median difference in the number of days until negative RT-PCR results between patients was studied.

RESULTS

Sixty-one patients with positive SARS-CoV2 swabs were admitted, 34 (55.7%) of whom were symptomatic. The most common symptom was nasal congestion (21/61, 34.3%), followed by generalised malaise and headache (12/6, 19.7%). A rash was detected in 5/61 (8.2%) of them. Fifty-five patients (90.1%) underwent investigations: 4 (7.4%) of them had lymphopenia, 4 (7.4%) had eosinopenia, 8 (14.5%) had eosinophilia, and platelets were elevated in 5 (9.1%) children. CRP was measured in 33/61 (54.1%) patients and all were normal. ESR levels were available for 11/61 (18%) patients and were elevated in 5 (45.5%). There was a statistically significant association between laboratory results and symptom expression (p = 0.011). The longest time until the first negative RT-PCR result was 39 days.

CONCLUSION

All children admitted who tested positive for SARS-CoV2 had mild symptoms and five had cutaneous manifestations. RT-PCR may remain positive for over one month.

Tuberculosis in Pediatric Solid Organ and Hematopoietic Stem Cell Recipients

Children undergoing solid organ and hematopoietic stem cell transplantation are at high risk of morbidity and mortality from tuberculosis (TB) disease in the post-transplant period. Treatment of TB infection and disease in the post-transplant setting is complicated by immunosuppression and drug interactions. There are limited data that address the unique challenges for the management of TB in the pediatric transplant population. This review presents the current understanding of the epidemiology, clinical presentation, diagnosis, management, and prevention for pediatric transplant recipients with TB infection and disease. Further studies are needed to improve diagnosis of TB and optimize treatment outcomes for these patients.

Placental transfer of the integrase strand inhibitors cabotegravir and bictegravir in the ex-vivo human cotyledon perfusion model

: Data on placental transfer is lacking for the recent HIV integrase inhibitors, bictegravir and cabotegravir, although their future use in pregnancy is to be expected. The objective of this study was to determine their transplacental pharmacokinetics. Maternal-to-fetal transfer was investigated using the open-circuit ex-vivo dually perfused human cotyledon model. Cabotegravir or bictegravir was added to a maternal perfusate containing 2 g/l of human albumin and antipyrine, a marker to validate the cotyledon's viability, and cotyledons were dually perfused for up to 90 min. For cabotegravir, in five experiments, the median (IQR 25-75) concentrations in the maternal and in the fetal compartments were, respectively, 550 ng/ml (344-788) and 48 ng/ml (37-54), with a maternal-to-fetal ratio of 10% (5-16) and a clearance index (in comparison with antipyrine transfer) of 22% (19-28). The median cotyledon accumulation index was 10% (2-21). For bictegravir, in six experiments, the median (IQR 25-75) concentrations in the maternal and in the fetal compartments were, respectively, 1650 ng/ml (1455-1960) and 126 ng/ml (112-142), with a maternal-to-fetal ratio of 7% (6-9.5) and a clearance index (in comparison with antipyrine transfer) of 21% (17-29). The median cotyledon accumulation index was 4% (3-5). Placental transfer of cabotegravir and bictegravir were low. This may not only limit the potential for fetal toxicities but also be a limit to their usefulness at the time of labor and delivery to reduce the risk of vertical HIV transmission. The safety and efficacy of these new integrase inhibitors in pregnancy require more investigation.

An exploratory non-randomized study of a 3-month electronic nicotine delivery system (ENDS) intervention with people accessing a homeless supported temporary accommodation service (STA) in Ireland

BACKGROUND

Smoking is endemic amongst people accessing homeless services, and they are disproportionately affected by smoking-related diseases. This paper reports on the results of a 3-month small scale intervention which explored the efficacy, challenges and opportunities of using electronic nicotine delivery systems (ENDS) to support cessation of tobacco smoking with people accessing an Irish supported temporary accommodation (STA) homeless service. It considers the results of this intervention with reference to the balance of harms between the use of vaping to support smoking cessation and continued smoking.

METHODS

Twenty-three participants were recruited. Demographic data, carbon monoxide (CO) measurements, homelessness status and smoking history were recorded. Participants were given an ENDS device and two 10-ml bottles containing e-liquid available in several flavours and at several strengths. Participants could pick up new bottles on a weekly basis. At weeks 1, 4, 8 and 12, the Fagerström Test and Mood and Physical Symptoms Scale (MPSS) were administered.

RESULTS

Over 75% of the residents in the participating hostel were recruited (23/30). However, there was a substantial loss to follow-up (n = 14) as a result of data protection issues, the transient nature of the population of interest and non-compliance with the intervention. Self-reported reductions in cigarette consumption were found to be statistically significant (p < 0.001). However, reductions in carbon monoxide measurements were not statistically significant. Decreases in Fagerström Nicotine Dependence Test were statistically significant (p = 0.001), but decreases in MPSS "urge to smoke" and "strength of urges" composite scores were not. Reported side effects included coughing, runny nose, bleeding nose, slight sweating, dizziness, increased phlegm and a burning sensation at the back of the throat. Barriers to engagement were peer norms, vaping restrictions in accommodation and adverse life events. Positive effects reported included increased energy, less coughing, better breathing and financial benefits. An improvement in the domain "poor concentration" was also found to be statistically significant (p = 0.040).

CONCLUSION

ENDS-based interventions may be effective with this population. Future research should aim to improve follow-up, consider including behavioural components and monitor health effects in relation to ongoing concerns around risks and the balance of harms.

Improving autism and developmental screening and referral in US primary care practices serving Latinos

LAY ABSTRACT

Latino children experience delays in access to diagnosis and treatment of autism spectrum disorder. Primary care-based screening of all children for autism spectrum disorder and referring them for services may reduce racial/ethnic differences and improve care. REAL-START, a yearlong screening intervention, was effective in increasing screening for autism spectrum disorder and general developmental delays, increasing therapy referrals, and shortening time for developmental assessment in primary care clinics with Latino patients.

Serological identification of SARS-CoV-2 infections among children visiting a hospital during the initial Seattle outbreak

Children are strikingly underrepresented in COVID-19 case counts. In the United States, children represent 22% of the population but only 1.7% of confirmed SARS-CoV-2 cases as of April 2, 2020. One possibility is that symptom-based viral testing is less likely to identify infected children, since they often experience milder disease than adults. Here, to better assess the frequency of pediatric SARS-CoV-2 infection, we serologically screen 1,775 residual samples from Seattle Children's Hospital collected from 1,076 children seeking medical care during March and April of 2020. Only one child was seropositive in March, but seven were seropositive in April for a period seroprevalence of ≈1%. Most seropositive children (6/8) were not suspected of having had COVID-19. The sera of seropositive children have neutralizing activity, including one that neutralized at a dilution > 1:18,000. Therefore, an increasing number of children seeking medical care were infected by SARS-CoV-2 during the early Seattle outbreak despite few positive viral tests.

Tracheostomy, ventilatory wean, and decannulation in COVID-19 patients

PURPOSE

COVID-19 patients requiring mechanical ventilation can overwhelm existing bed capacity. We aimed to better understand the factors that influence the trajectory of tracheostomy care in this population to facilitate capacity planning and improve outcomes.

METHODS

We conducted an observational cohort study of patients in a high-volume centre in the worst-affected region of the UK including all patients that underwent tracheostomy for COVID-19 pneumonitis ventilatory wean from 1st March 2020 to 10th May 2020. The primary outcome was time from insertion to decannulation. The analysis utilised Cox regression to account for patients that are still progressing through their tracheostomy pathway.

RESULTS

At the point of analysis, a median 21 days (IQR 15-28) post-tracheostomy and 39 days (IQR 32-45) post-intubation, 35/69 (57.4%) patients had been decannulated a median of 17 days (IQR 12-20.5) post-insertion. The overall median age was 55 (IQR 48-61) with a male-to-female ratio of 2:1. In Cox regression analysis, FiO₂ at tracheostomy ≥ 0.4 (HR 1.80; 95% CI 0.89-3.60; p = 0.048) and last pre-tracheostomy peak cough flow (HR 2.27; 95% CI 1.78-4.45; p = 0.001) were independent variables associated with prolonged time to decannulation.

CONCLUSION

Higher FiO₂ at tracheostomy and higher pre-tracheostomy peak cough flow are associated with increased delay in COVID-19 tracheostomy patient decannulation. These finding comprise the most comprehensive report of COVID-19 tracheostomy decannulation to date and will assist service planning for future peaks of this pandemic.
