RESUMO

INTRODUCTION: The study aimed to determine the effectiveness of an intervention for unhealthy visual behaviors of school-age children using a wearable device (Clouclip). METHOD: The design was a self-controlled prospective study. Clouclip, with the vibration alert disabled, was first applied to measure baseline near-work behaviors in the first week. The vibration alert was then enabled to signal unhealthy visual behaviors (near-work distance < 30 cm and >5 seconds, or near-work distance <60 cm for >45 minutes) for 3 weeks. Near-work behaviors were measured again at the first week and the first month after intervention, respectively. The changes in behaviors between the baseline and the first week and the first month after intervention were analyzed. RESULTS: Sixty-seven subjects were eligible for this experiment (the mean age 10.45 ±â€Š0.50 years, 34 boys). Children who logged sufficient wearing time (12.30 ±â€Š0.18 hours on weekdays and 12.16 ±â€Š0.23 hours on weekends) were included for analysis. The average daily near-work distance was significantly increased after the vibration intervention. The time ratio of near-work activity <30 cm to the total <60 cm and the frequency of continuous near-work (distance <60 cm and continuous time >30 minutes) were significantly decreased after the intervention. Although some of the effects were reversed with time following the intervention, some were observed to be maintained until the end of the observation period, and the improvement of the behaviors was more prominent in children who had a shorter near-work distance (<30 cm) at baseline. CONCLUSIONS: In conclusion, Clouclip can significantly modify near-work behaviors in school-age children and it can last a certain period of time. If these behaviors are causes of myopia development and progression, Clouclip might provide a strategy for managing myopia.

RESUMO

To investigate the relationship amongst human growth hormone (HGH), sex, and age groups.A cross-sectional study was conducted on a health check-up population from Wannan area of China from 2014 to 2016. The study involved 6843 individuals aged 23 to 85 years. Logistic regression analysis and smooth curve were applied to determine the relationship amongst age, sex, and HGH.The average level of HGH in the population was 0.37 ±â€Š0.59 ng/mL. There were significant differences in sex, age, body mass index (BMI), triglycerides (TG), total cholesterol (TC), systolic blood pressure (SBP), diastolic blood pressure (DBP), and glucose (GLU) amongst different quartiles of HGH (P < .001). A U-shape relationship was established between HGH and age. After sex stratification, the results showed that the thresholds of age were 60 years in women, and 50 years in men, after adjusting for body mass index, triglycerides, total cholesterol, blood pressure, and blood glucose. Logistic regression showed that HGH level decreased in women aged <60 years (OR = 1.472, P < .001) and increased in men aged >50 years (OR = 0.711, P < .001). So the distributive characteristics of HGH concentration vary with sex and age group.

RESUMO

BACKGROUND: Previous studies have reported the association between Mycoplasma fermentans (M. fermentans) and the risk of human immunodeficiency virus 1 (HIV-1) infection, but the results were inconsistent. The present study aims to systematically review reported studies on M. fermentans and its association with HIV-1 infection, as well as to summarize the findings using a meta-analysis. METHODS: Studies meeting the inclusion criteria in the PubMed, Embase, China National Knowledge Infrastructure, WanFang Data, and Chongqing VIP databases up to March 2019 were identified. Cochran Q and I statistics were used to assess heterogeneity. Additionally, pooled odds ratio (OR) with 95% confidence intervals (CI) were calculated and displayed by Forest plots. Also, the funnel plot, Begg test, and Egger test were used to evaluate potential publication bias. In addition, the source of heterogeneity was investigated by subgroup and sensitivity analyses. RESULTS: A total of 11 studies comprising 1028 HIV-1-positive patients and 1298 controls were ultimately included in this meta-analysis. Our results indicated that M. fermentans could increase the risk of HIV-1 infection among humans (OR = 3.66, 95%CI 1.26-10.64). Subgroup analysis showed that the risk of HIV-1 infection associated with M. fermentans was, based on the geographical distribution, 1.19 (95%CI 0.33-4.33) in Europe, 2.83 (95%CI 0.94-8.52) in United States, 11.92 (95%CI 3.93-36.15) in Asia; based on the source of the sample, 2.97 (95%CI 0.89-9.95) in blood samples, 4.36 (95%CI 1.63-11.68) in urine samples; based on the detection method, 2.80 (95%CI 0.72-10.96) with the polymerase chain reaction method, 5.54 (95%CI 1.21-25.28) with other detection methods; based on the source of controls, 1.91 (95%CI 0.53-6.89) in sexually transmitted diseases individuals, and 8.25 (95%CI 2.16-31.60) in health individuals. CONCLUSION: Our study revealed evidence of the association between M. fermentans and HIV-1 infection. Considering the heterogeneity, further studies are warranted to understand the relationship between M. fermentans and HIV-1 infection.

RESUMO

The frailty represents a key determinant of elderly clinical assessment, especially because it allows the identification of risk factors potentially modifiable by clinical and therapeutic interventions. The frailty assessment in elderly patients usually is made by using of Fried criteria. However, to assess the frailty in cirrhotic patients, multiple but different tools are used by researchers. Thus, we aimed to compare frailty prevalence in elderly patients with well-compensated liver cirrhosis and without cirrhosis, according to Fried criteria.Among 205 elderly patients screened, a total of 148 patients were enrolled. The patients were divided into 2 groups according to the presence/absence of well-compensated liver cirrhosis.After clinical examination with conventional scores of cirrhosis, all patients underwent anthropometric measurements, nutritional, biochemical, comorbidity, and cognitive performances. Frailty assessment was evaluated according to Fried frailty criteria.Unexpectedly, according to the Fried criteria, non-cirrhotic patients were frailer (14.2%) than well-compensated liver cirrhotic patients (7.5%). The most represented Fried criterion was the unintentional weight loss in non-cirrhotic patients (10.1%) compared to well-compensated liver cirrhotic patients (1.4%). Moreover, cumulative illness rating scale -G severity score was significantly and positively associated with frailty status (r = 0.234, P < .004). In a multivariate linear regression model, only female gender, body mass index and mini nutritional assessment resulted associated with frailty status, independently of other confounding variables.Despite the fact that elderly cirrhotic patients are considered to be frailer than the non-cirrhotic elderly patient, relying solely on "mere visual appearance," our data show that paradoxically non-cirrhotic elderly patients are frailer than elderly well-compensated liver cirrhotic patients. Thus, clinical implication of this finding is that frailty assessment performed in the well-compensated liver cirrhotic patient can identify those cirrhotic patients who may benefit from tailored interventions similarly to non-cirrhotic elderly patients.

RESUMO

We aimed to evaluate the clinical significance of bacterial coexistence and the coinfection dynamics between bacteria and respiratory viruses among young children. We retrospectively analyzed clinical data from children aged < 5 years hospitalized with a community-acquired single respiratory viral infection of influenza, adenovirus, or RSV during 2 recent consecutive influenza seasons. Remnant respiratory specimens were used for bacterial PCR targeting Moraxella catarrhalis, Haemophilus influenzae, Streptococcus pneumoniae, and Staphylococcus aureus.A total of 102 children were included; median age was 0.8 years and 44.1% had underlying comorbidities. Overall, 6.8% (7/102) of cases were classified as severe diseases requiring intensive care unit admission and/or mechanical ventilation and ranged from 8.8% for a patient with RSV and 7.6% for those with adenovirus to 0% for those with influenza viruses. The overall viral-bacterial codetection rate was 59.8% (61/102); M catarrhalis was the most frequent (33.3%), followed by H influenzae (31.4%). Influenza cases showed higher bacterial codetection rates (80.0%; 8/10) compared with those with adenoviruses (69.2%; 9/13) and RSV (55.7%; 44/79). S pneumoniae and H influenzae codetections were associated with reduced severity (aOR, 0.24; 95% CI, 0.07-0.89), and reduced risk of wheezing (aOR, 0.36; 95% CI, 0.13-0.98), respectively.We observed the interactions between respiratory viruses and bacteria and the clinical significance of viral-bacterial coexistence in upper airway on disease severity. Future study will be necessary to elucidate the active interactions between different viruses and bacteria and give clues to risk stratified strategy in the management of respiratory infections among young children.

RESUMO

Atrial fibrillation (AF) is an important complication of acute myocardial infarction (AMI). The association between AF and serum lipid profile is unclear and statin use for lowering the incidence of new-onset AF remains controversial. The objective of this study was to investigate whether statins confer a beneficial effect on AF after AMI.Data available in the Taiwan National Health Insurance Research Database on 32886 AMI patients between 2008 and 2011 were retrospectively analyzed. Total 27553 (83.8%) had complete 1-yr follow-up data. Cardiovascular outcomes were analyzed based on the baseline characteristics and AF type (existing, new-onset, or non-AF). AF groups had significantly higher incidence of heart failure (HF), stroke, all-cause death, and major adverse cardiac and cerebrovascular event (MACCE) after index AMI (all P < .05). In contrast, myocardial re-infarction (re-MI) was not significantly different among the three groups (P = .95). Statin use tended to be associated with lower risk of new-onset AF after AMI (HR: 0.935; 95% confidence interval (CI): 0.877-0.998; P = .0427).Existing AF and new-onset AF subgroups had similar cardiovascular outcomes after AMI and were both inferior to the non-AF group. Statin tended to reduce new-onset AF after AMI.

RESUMO

Human immunodeficiency virus (HIV) testing is important for prevention and treatment. Ending the HIV epidemic is unattainable if significant proportions of people living with HIV remain undiagnosed, making HIV testing critical for prevention and treatment. The Centers for Disease Control and Prevention (CDC) recommends routine HIV testing for persons aged 13 to 64 years in all health care settings. This study builds on prior research by estimating the extent to which HIV testing occurs during physician office and emergency department (ED) post 2006 CDC recommendations.We performed an unweighted and weighted cross-sectional analysis using pooled data from 2 nationally representative surveys namely National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 2009 to 2014. We assessed routine HIV testing trends and predictive factors in physician offices and ED using multi-stage statistical survey procedures in SAS 9.4.HIV testing rates in physician offices increased by 105% (5.6-11.5 per 1000) over the study period. A steeper increase was observed in ED with a 191% (2.3-6.7 per 1000) increase. Odds ratio (OR) for HIV testing in physician offices were highest among ages 20 to 29 ([OR] 7.20, 99% confidence interval [CI: 4.37-11.85]), males (OR 1.34, [CI: 0.91-0.93]), African-Americans (OR 2.97, [CI: 2.05-4.31]), Hispanics (OR 1.80, [CI: 1.17-2.78]), and among visits occurring in the South (OR 2.06, [CI: 1.23-3.44]). In the ED, similar trends of higher testing odds persisted for African Americans (OR 3.44, 99% CI 2.50-4.73), Hispanics (OR 2.23, 99% CI 1.65-3.01), and Northeast (OR 2.24, 99% CI 1.10-4.54).While progress has been made in screening, HIV testing rates remains sub-optimal for ED visits. Populations visiting the ED for routine care may suffer missed opportunities for HIV testing, which delays their entry into HIV medical care. To end the epidemic, new approaches for increasing targeted routine HIV testing for populations attending health care settings is recommended.

RESUMO

The purpose of this study was to determine the factors associated with parenteral nutrition-associated liver disease (PNALD) in infants who underwent surgery for necrotizing enterocolitis (NEC) and followed up the postoperative outcomes for long term parenteral nutrition (PN).This study included a retrospective review of 87 infants with NEC and managed surgically from July 2007 to May 2017 at the Children's Hospital, Chongqing Medical University. Clinical data and procedure information were collected and analyzed.Among the infants included, 16.1% of patients developed PNALD. Multivariable logistic regression analysis revealed progressive clinical deterioration (OR, 5.47; 95% CI, 1.10-26.96; P = .037) was independent risk factor for PNALD whereas congenital heart disease (OR, 0.068; 95% CI, 0.008-0.55; P = .012) presentation served as a protective factor.The current data suggested the distinct disease process for cardiac patients with NEC, which might help in the prevention and treatment of PNALD for patients with NEC.

RESUMO

OBJECTIVE: Gout and hyperuricemia are common public health problem. There has been no epidemiological survey of gout and hyperuricemia in Tibet Autonomous Region, the southwest of China. Therefore, we estimated the prevalence of gout and hyperuricemia in Luoma Town, Naqu City, Tibet Autonomous Region of China. METHODS: A population-based cross-sectional survey was conducted among 1458 residents of Luoma Town, Tibet Autonomous Region, age ≥40 years. We used questionnaires in face-to-face interviews, anthropometric measurements and serum uric acid test. Hyperuricemia was defined as serum uric acid level ≥7 mg/dl in men and ≥6 mg/dl in women. The definition of gout in this study was on the basis of new 2015ACR/EULAR classification criteria. RESULTS: Nine hundred eighty-nine participants completed all items of gout and 818 participants attended to be taken blood samples for serum UA levels test. The overall crude prevalence of gout and hyperuricemia was 0.30% and 1.83% respectively. It was more prevalent in men than in women (2.86% vs 0.75%, P = .034) in hyperuricemia group. Tibetan had a lower age-standardized prevalence of gout 0.26% (95% confidence interval (CI): 0%-0.60%) and hyperuricemia 2.05% (95% confidence interval (CI): 0.99%-3.44%) compared with the China Health and Retirement Longitudinal Study results. CONCLUSION: This is the first large-scale population-based survey to demonstrate the prevalence of gout and hyperuricemia of the middle-aged and elderly population in Tibet Autonomous Region, China. The prevalence of gout and hyperuricemia is relatively lower than other places in China, and that might be influenced by ethnicity, genetic and environment factors. These findings will be useful for the future researches and health care strategies.

RESUMO

BACKGROUND: Fixed appliances have been the mainstream for orthodontic treatment, while clear aligners, such as Invisalign system, have become increasingly popular. The prevalence of apical root resorption (ARR) in patients with clear aligners is still controversial. The aim of this study was to investigate and compare the prevalence and severity of ARR in patients treated with clear aligners and fixed appliances using cone beam computed tomography (CBCT). MATERIALS AND METHODS: A total of 373 roots from 70 subjects, with similar baseline characteristics and the ABO discrepancy index scores (i.e., treatment difficulty), were included into two groups: the clear aligners group (Invisalign, Align Technology, California, USA) and fixed appliances group (Victory Series; 3 M Unitek, California, USA). Root length of each anterior tooth was measured on the CBCT images by two blinded investigators. The ARR on each tooth was calculated as the difference of root length before and after orthodontic treatment. Chi-square test and paired t test was used to compare the ARR between the two groups as well as before and after orthodontic treatments. RESULTS: Prevalence of ARR in the clear aligners group (56.30%) was significantly lower than that in the fixed appliances group (82.11%) (P < 0.001). The severity of ARR in the clear aligners group (0.13 ± 0.47 mm) was significantly less than that in the fixed appliances group (1.12 ± 1.34 mm) (P < 0.001). The most severe ARR was found on the maxillary canine (1.53 ± 1.92 mm) and lateral incisor (1.31 ± 1.33 mm) in the fixed appliances group; the least ARR was found on the mandibular canine (- 0.06 ± 0.47 mm) and lateral incisor (0.04 ± 0.48 mm) in the clear aligners group (P < 0.001). CONCLUSIONS: The prevalence and severity of ARR measured on CBCT in patients with clear aligners were less than those in patients with fixed appliances.

RESUMO

Infections with the liver fluke Fasciola hepatica remain a serious problem in dairy herds causing significant production losses. In sheep, a strong relationship between F. hepatica infections and an increase in serum ketone bodies due to reduced feed intake and liver damage was demonstrated. We hypothesized that F. hepatica infections might contribute to an increase in milk ketone bodies in dairy herds. Thus, the objective of the study was to estimate the association between F. hepatica bulk tank milk (BTM) antibodies and milk production parameters (milk yield, milk protein, fat yield), somatic cell count (SCC) and the milk ketone bodies ß-hydroxybutyrate (BHB) and acetone, inferred from Fourier transform infrared (FTIR) spectrometry, via linear mixed model analysis. A further aim was to follow up the F. hepatica seroprevalence in dairy herds in the northern German region East Frisia. We collected BTM samples between October and December from 1022 herds in 2017 and 1318 herds in 2018. Overall, 33.1 % of the herds tested positive in 2017 and 37.0 % in 2018, showing decreased F. hepatica seroprevalences compared to prior seroprevalence studies in the same region in 2010, 2008 and 2006 (> 45 % positive herds). We estimated a significant negative association (P < 0.001) between herd F. hepatica infection category and average milk yield with a loss of -1.62 kg per cow per day in strongly infected herds compared to BTM ELISA negative herds. Moreover, F. hepatica infection category had a significant effect on herd average milk protein and fat yield (P < 0.001), showing a decrease of 0.06 kg for both parameters from BTM ELISA negative herds to strongly infected herds. No significant association with milk SCC was found (P = 0.664). Regarding ketone bodies, we estimated significant higher average BHB values in strongly infected herds compared to the other three infection categories in the model analysis (P = 0.002). The association between F. hepatica infection category and acetone values was not significant (P = 0.079). Besides primary ketosis, fasciolosis should be considered as differential diagnosis in dairy herds with increased BHB values.

RESUMO

Fasciola hepatica (liver fluke) is a widespread parasite infection of livestock in Victoria, South-eastern Australia, where high rainfall and a mild climate is suitable for the main intermediate host Austropeplea tomentosa. The aims of this study were to quantify the prevalence and intensity of F. hepatica in dairy cattle in the irrigated dairy regions of Victoria and determine if triclabendazole resistance was present in infected herds. Cattle in 83 herds from the following six irrigation regions were tested for F. hepatica: Macalister Irrigation District (MID), Upper Murray (UM), Murray Valley (MV), Central Goulburn (CG), Torrumbarry (TIA) and Loddon Valley (LV). Twenty cattle from each herd were tested using the F. hepatica faecal egg count (FEC) as well as the coproantigen ELISA (cELISA). The mean individual animal true prevalence of F. hepatica across all regions was 39 % (95 % credible interval [CrI] 27%-51%) by FEC and 39 % (95 % CrI 27%-50%) by cELISA with the highest true prevalence (75-80 %) found in the MID. Our results show that 46 % of the herds that took part in this study were likely to experience fluke-associated production losses, based on observations that herd productivity is impaired when the true within-herd prevalence is > 25 %. Using the FEC and cELISA reduction tests, triclabendazole resistance was assessed on 3 herds in total (2 from the 83 in the study; and 1 separate herd that did not take part in the prevalence study) and resistance was confirmed in all 3 herds. This study has confirmed that F. hepatica is endemic in several dairy regions in Victoria: triclabendazole resistance may be contributing to the high prevalence in some herds. From our analysis, we estimate that the state-wide economic loss associated with fasciolosis is in the order of AUD 129 million (range AUD 38-193 million) per year or about AUD 50,000 (range AUD 15,000-75,000) per herd per year.

RESUMO

Each year, excessive drinking accounts for one in 10 deaths among U.S. adults aged 20-64 years (1), and approximately 90% of adults who report excessive drinking* binge drink (i.e., consume five or more drinks for men or four or more drinks for women on a single occasion) (2). In 2015, 17.1% of U.S. adults aged ≥18 years reported binge drinking approximately once a week and consumed an average of seven drinks per binge drinking episode, resulting in 17.5 billion total binge drinks, or 467 total binge drinks per adult who reported binge drinking (3). CDC analyzed 2011-2017 Behavioral Risk Factor Surveillance System (BRFSS) data to assess trends in total annual binge drinks per adult who reported binge drinking in the United States overall and in the individual states. The age-adjusted† total annual number of binge drinks per adult who reported binge drinking increased significantly from 472 in 2011 to 529 in 2017. Total annual binge drinks per adult who reported binge drinking also increased significantly from 2011 to 2017 among those aged 35-44 years (26.7%, from 468 to 593) and 45-64 years (23.1%, from 428 to 527). The largest percentage increases in total binge drinks per adult who reported binge drinking during this period were observed among those without a high school diploma (45.8%) and those with household incomes <$25,000 (23.9%). Strategies recommended by the Community Preventive Services Task Force§ for reducing excessive drinking (e.g., regulating alcohol outlet density) might reduce binge drinking and related health risks.

RESUMO

Transgender women* in the United States are disproportionately affected by human immunodeficiency virus (HIV) infection because of multiple factors, including stigma related to gender identity, unstable housing, limited employment options, and high-risk behaviors, such as sex work, unprotected receptive anal intercourse, and injection drug use, that tend to increase their vulnerability to becoming infected with HIV (1,2). In a recent meta-analysis of 88 U.S. studies conducted during 2006-2017, the mean estimated laboratory-confirmed prevalence of HIV infection among transgender women was 14.2%, and the mean self-reported prevalence estimate was 21.0% (3). The Ending the HIV Epidemic initiative calls for accelerating the implementation of evidence-based strategies in the right geographic areas targeted to the right persons to end the HIV epidemic in the United States (4). HIV partner services are effective strategies offered by public health workers to persons with a diagnosis of HIV infection (index persons) and their sex or needle-sharing partners (partners), who are notified of potential HIV exposure and offered HIV testing and related services. CDC analyzed HIV partner services data submitted by 61 health departments† during 2013-2017. Among 208,304 index persons, 1,727 (0.8%) were transgender women. Overall, 71.5% of index transgender women were interviewed for partner services, which was lower than that for all index persons combined (81.1%). Among 1,089 transgender women named as partners by index persons, 71.2% were notified of potential HIV exposure, which was lower than that for all partners combined (77.1%). Fewer than half (46.5%) of notified transgender women partners were tested for HIV, and approximately one in five (18.6%) of those who were tested received a new diagnosis of HIV infection, slightly higher than for all partners combined (17.6%). Additional efforts are needed to effectively implement partner services among transgender women and identify those whose infection with HIV is undiagnosed, provide timely prevention and care services, reduce HIV transmission, and contribute to ending the HIV epidemic.

RESUMO

Multiple genetically distinct influenza B/Victoria lineage viruses have cocirculated in the United States recently, circulating sporadically during the 2018-19 season and more frequently early during the 2019-20 season (1). The beginning of the 2019-20 influenza season in Louisiana was unusually early and intense, with infections primarily caused by influenza B/Victoria lineage viruses. One large pediatric health care facility in New Orleans (facility A) reported 1,268 laboratory-confirmed influenza B virus infections, including 23 hospitalizations from July 31 to November 21, 2019, a time when influenza activity is typically low. During this period, Louisiana also reported one pediatric death associated with influenza B virus infection. An investigation of the influenza B virus infections in Louisiana, including medical and vaccine record abstraction on 198 patients, primarily from facility A, with sporadic cases from other facilities in the state, found that none of the patients had received 2019-20 seasonal influenza vaccine, in part because influenza activity began before influenza vaccination typically occurs. Among 83 influenza B viruses sequenced from 198 patients in Louisiana, 81 (98%) belonged to the recently emerged B/Victoria V1A.3 genetic subclade. Nationally, to date, B/Victoria viruses are the most commonly reported influenza viruses among persons aged <25 years (2). Of the 198 patients in the investigation, 95% were aged <18 years. Although most illnesses were uncomplicated, the number of hospitalizations, clinical complications, and the reported pediatric death in Louisiana serve as a reminder that, even though influenza B viruses are less common than influenza A viruses in most seasons, influenza B virus infection can be severe in children. All persons aged ≥6 months should receive an annual influenza vaccination if they have not already received it (3). Antiviral treatment of influenza is recommended as soon as possible for all hospitalized patients and for outpatients at high risk for influenza complications (including children aged <2 years and persons with underlying medical conditions) (4).

RESUMO

Control of communicable diseases in children, including respiratory and diarrheal illnesses that affect U.S. school-aged children, might require public health preventive efforts both in the home and at school, a primary setting for transmission. National Health Interview Survey (NHIS) data on school absenteeism and gastrointestinal and respiratory illnesses in the United States during 2010-2016 were analyzed to examine their associations with income. Prevalence of gastrointestinal and respiratory illnesses (queried for the 2 weeks preceding the survey) increased as income decreased. The likelihood of missing any school days during the past year decreased with reduced income. However, among children who missed school, those from low-income households missed more days of school than did children from higher income households. Although the reason for absenteeism cannot be ascertained from this analysis, these data underscore the importance of preventive measures (e.g. hand hygiene promotion and education) and the opportunity for both homes and schools to serve as important points for implementation of public health preventive measures, including improved hand hygiene practices.

RESUMO

Birth defects are a leading cause of infant mortality in the United States, accounting for 20.6% of infant deaths in 2017 (1). Rates of infant mortality attributable to birth defects (IMBD) have generally declined since the 1970s (1-3). U.S. linked birth/infant death data from 2003-2017 were used to assess trends in IMBD. Overall, rates declined 10% during 2003-2017, but decreases varied by maternal and infant characteristics. During 2003-2017, IMBD rates decreased 4% for infants of Hispanic mothers, 11% for infants of non-Hispanic black (black) mothers, and 12% for infants of non-Hispanic white (white) mothers. In 2017, these rates were highest among infants of black mothers (13.3 per 10,000 live births) and were lowest among infants of white mothers (9.9). During 2003-2017, IMBD rates for infants who were born extremely preterm (20-27 completed gestational weeks), full term (39-40 weeks), and late term/postterm (41-44 weeks) declined 20%-29%; rates for moderate (32-33 weeks) and late preterm (34-36 weeks) infants increased 17%. Continued tracking of IMBD rates can help identify areas where efforts to reduce IMBD are needed, such as among infants born to black and Hispanic mothers and those born moderate and late preterm (32-36 weeks).

RESUMO

CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders continue to investigate a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). EVALI patients in Illinois, Utah, and Wisconsin acquired tetrahydrocannabinol (THC)-containing products primarily from informal sources (2,3). This report updates demographic characteristics and self-reported sources of THC- and nicotine-containing e-cigarette, or vaping, products derived from EVALI patient data reported to CDC by state health departments. As of January 7, 2020, among 1,979 (76%) patients with available data on substance use, a total of 1,620 (82%) reported using any THC-containing products, including 665 (34%) who reported exclusive THC-containing product use. Use of any nicotine-containing products was reported by 1,128 (57%) patients, including 264 (13%) who reported exclusive nicotine-containing product use. Among 809 (50%) patients reporting data on the source of THC-containing products, 131 (16%) reported acquiring their products from only commercial sources (i.e., recreational dispensaries, medical dispensaries, or both; vape or smoke shops; stores; and pop-up shops), 627 (78%) from only informal sources (i.e., friends, family, in-person or online dealers, or other sources), and 51 (6%) from both types of sources. Among 613 (54%) EVALI patients reporting nicotine-containing product use with available data on product source, 421 (69%) reported acquiring their products from only commercial sources, 103 (17%) from only informal sources, and 89 (15%) from both types of sources. Adolescents aged 13-17 years were more likely to acquire both THC- and nicotine-containing products from informal sources than were persons in older age groups. The high prevalence of acquisition of THC-containing products from informal sources by EVALI patients reinforces CDC's recommendation to not use e-cigarette, or vaping, products that contain THC, especially those acquired from informal sources. Although acquisition of nicotine-containing products through informal sources was not common overall, it was common among persons aged <18 years. While the investigation continues, CDC recommends that the best way for persons to ensure that they are not at risk is to consider refraining from the use of all e-cigarette, or vaping, products.
