Epstein-barr virus /Helicobacter pylori coinfection and gastric cancer: the possible role of viral gene expression and shp1 methylation
Authors: Estaji Fatemeh , Nasr Esfahani Bahram , Zibaee Saeed , Sanei Mohammad Hossein , Moghim Sharareh
Published: December 2022

Background and Objectives: Among the various factors involved in the development of gastric cancer (GC), infectious agents are one of the mostimportant causative inducers. This study aimed to investigate the possible role of EBV gene ex- pression on SHP1 methylation in co-infection with Helicobacter pylori in patients with GC.
Materials and Methods: Formalin-fixed paraffin-embedded samples were obtained from 150 patients with gastrointestinal disorders. The presence of the H.pylori and EBV genome were examined by PCR. The expression level of viral gene transcripts and methylation status of the SHP1 cellular gene was assessed by quantitative real-time PCR and methyl-specific PCR.
Results: EBV and H. pylori coinfection were reported in 5.6% of patients. The mean DNA viral load wassignificant in pa- tients coinfected with cagA-positive H. pylori (P= 0.02). The expression of BZLF1 and EBER was associated with GC. Also, the expression level of BZLF1in GC tissues was significantly higher in coinfection (P = 0.01). SHP1 methylation frequency was higher in the GC group than in the controlgroup (P = 0.04). The correlation between the methylation rate and the H. py- lori infection was highly significant (P<0.0001). The strongest positive correlationwas observed in GC specimens between SHP1 methylation and H. pylori cagA-positive strains (p= 0.003).
Conclusion: Our results suggested that cagA might involve in the elevation of EBV lytic gene expression and SHP1 methyl- ation, and the development ofgastric cancer. Understanding the mechanism of EBV H. pylori - cagA + coinfection, as well as host epigenetic changes, can play an important role in diagnosing and preventing gastric cancer.

Published: December 2022

Background and Objectives: A great diversity of factors including viruses such as human herpes virus 1&2 (HHV-1&2), human herpes virus 5 (HHV-5), andhepatitis B virus (HBV) play key roles in sterility and it is worth noting that male infertil- ity accounts for nearly 50% of barrenness, globally. In this regard, weevaluated the prevalence of the aforementioned viruses in semen specimens of two distinct groups of men referred to Novin Infertility Center in Mashhad, Iran.
Materials and Methods: In this cross-sectional study, 300 semen samples were collected from 150 infertile and 150 fertile men. Subsequently, genomic DNAwas extracted before performing multiplex polymerase chain reaction (PCR). Eventually, the results were analyzed via SPSS Statistics V.16.0.
Results: Out of 300 specimens, 183 (61.1%) were positive at least for one of the forenamed viruses; genome detection of HHV-1&2, HHV-5, and HBV were 27%, 18%, 36.66%, and 4%, respectively.
Conclusion: The current study found no correlation between infertility and HBV, HHV-5, and HHV-1&2, which may have to do with factors like sample size,the geographical distribution of the viruses, and the lifestyle (sexual behavior) of the participants. These results emphasize the implementation of such studies on a broader scale to determine the exact factors involved in infertility.

Authors: Patel T.P. , Patil D.B. , Chaudhary G.R. , Bhadesiya C.M.
Published: December 2022

Background: Tremendous achievements have been made in diagnostic and therapeutic aspects of digestive tract affections of bovines throughout the world, wherein clinical traumatic reticuloperitonitis (TRP) is the most commonly reported and studied condition in bovines. TRP is accidental ingestion of foreign body (metallic or non-metallic; penetrating or non-penetrating) objects, which generally get lodged or penetrate the reticulum. The reticulum plays a crucial role in the motility of the digestive tract in bovines and so several invasive and noninvasive methods are used for reticular examination. Hence, the ultrasonographic evaluation of reticular morphometric parameters is the need of the hour. Methods: The present study was undertaken to evaluate ultrasonographic morphometry of reticulum in bovines (Group I, six clinically healthy cattle and Group II, six clinically healthy buffaloes) at the Postgraduate Institute of Veterinary Education and Research, Kamdhenu University, Rajpur (Nava), Himmatnagar, Gujarat. For ultrasonography, using Esaote MyLabDelta Veterinary Ultrasound System with convex transducer (3-5 MHz), a standing left post-xiphoid paramedian approach was adopted. The morphometric parameters viz. half-moon-shaped reticular wall (RW), RW thickness, RW distance from the parietal peritoneum and the roughly triangular area between RW, cranio-ventral rumen sac and diaphragm were evaluated. Result: The mean RW thickness (Buffalo-5.33±0.58 mm; Cattle-4.53±0.33 mm), mean distance of the closest point of the RW from the peritoneum (25.77±3.23 mm; 13.07±0.67 mm) and mean triangular area (10.21±4.42 cm²; 4.94±0.52 cm²) were higher in healthy buffaloes than cattle.
Bystander Opportunity, Actions, and Inaction in Suspected Intimate Partner Violence: Differences Between Graduate and Undergraduate Students
Authors: Palmer Jane E. , Hoxmeier Jill
Published: December 2022

Limited research examines graduate student experiences with intimate partner violence (IPV) or bystander intervention. In this exploratory study, we compare the extent of opportunity to intervene in suspected IPV, how students tried to help, and barriers to intervention for undergraduate (n= 698) and graduate students (n= 967) at one university using data from stratified random samples of students. Graduate students indicated significantly less opportunity to intervene than undergraduate students (16.2% vs. 35.5%). Among students with the opportunity, however, similar proportions of undergraduate and graduate students tried to help, with most confronting the situation directly. Among those who did not try to help, graduate students commonly endorsed “not knowing what to do,” suggesting an opportunity to enhance prosocial intervention skills among this population through targeted bystander-based training initiatives.

Background: Research shows that psychiatric staff lack clinical confidence working with voice hearers. Simulation training is promising but staff input is limited. Aim: The present study aimed to qualitatively investigate ward staff experience of working with voice hearers
and their perspectives on simulation training. Method: Multidisciplinary psychiatric ward staff participated in semi-structured interviews on their experience of working with voice hearers and their views and recommendations on simulation training. Participants included seven nurses,
five healthcare assistants, and three activities co-ordinators. Results: Following thematic analysis, staff experience themes included Negative impact on therapeutic relationship, Clinical experience improves understanding of voice hearing, Empathy for voice hearers,
Challenges of managing risk, Lack of subjective understanding of voice hearing, Limited training for working with voice hearers and Lack of clinical confidence. Views on simulation training themes included Potential to improve subjective understanding, Anxieties
about emotional responses, Keenness to participate and Potential to improve clinical confidence. Simulation training recommendation themes included Incorporate practical, skills-based elements, Invite all mental health staff to participate, andUse
genuine voice hearer experiences. Conclusion: Lack of subjective understanding and clinical confidence was linked to training limitations, but skills-based simulation training was endorsed as a valuable method to improve staff understanding, confidence, and quality of care.
Pancreaticoduodenectomy as an option for treating a hemodynamically unstable traumatic pancreatic head injury with a pelvic bone fracture in Korea: a case report
Authors: Jeong Sung Yub , Lee Yoonhyun , Lee Hojun
Published: December 2022

Pancreatic trauma occurs in 0.2% of patients with blunt trauma and 5% of severe abdominal injuries, which are associated with high mortality rates (up to 60%). Traumatic pancreatoduodenectomy (PD) has significant morbidity and appreciable mortality owing to complicating factors, associated injuries, and shock. The initial reconstruction in patients with severe pancreatic injuries aggravates their status by causing hypothermia, coagulopathy, and acidosis, which increase the risk for early mortality. A staging operation in which PD follows damage control surgery is a good option for hemodynamically unstable patients. We report the case of a patient who was treated by staging PD for an injured pancreatic head.

Authors: Musa Kabiru Saidu , Mairiga Tahir Hussaini , Yakubu Yahaya
Published: December 2022

This article is carried out through an analysis of the influence of crude oil prices on the standard of living in Nigeria by using additional variables as supporters, such as crude oil income, inflation, and exchange rates. According to data availability, the utilization data used in this study is the annual time series data from 1981-2019. The main findings are: (1) there is a long-term equilibrium connection among the series. (2) crude oil price has a negative impact on the standard living. (3) crude oil revenue negatively affects the standard of living. (4) inflation has a negative impact on the standard of living. (5) exchange rate positively affects the standard of living. (6) convergence speed indicates that system movement to the equilibrium path is quick. Therefore, this implies that despite the abundance of oil in the country. The masses do not witness its impact. Diagnostic checks confirmed the perfectness of the model. DOLS, FMOLS and CCR as robustness checks revealed similar results with ARDL long-run results.

Authors: Panjaitan Makmur Tradesman Hasudungan
Published: December 2022

This study aims to examine the effect of financial development on tourism demand in member countries of Association of Southeast Asian Nations (ASEAN). The indicators are financial development index; financial institution depth index; financial institutional access index; and financial institutions efficiency index. Several control variables employed in this study are consumer price index, health expenditure, poor air quality, and trade openness. This study uses panel data between 2010 and 2018 from 10 ASEAN countries. Data are sourced from international institutions such as the World Bank, United Nation of World Tourism Organization (UNWTO), International Monetary Fund (IMF), and World Health Organization (WHO). The method used in the analysis is the static panel data regression. The results show that financial development has a positive effect on tourism demand. In terms of control variables’ impact, consumer price index, health expenditure and trade openness have a positive impact, whereas poor air quality has a negative impact. The current study’s implication on policy making is to develop the financial sector by increasing the number of ATMs and improving the mobile banking facilities
African Continental Free Trade Area Agreement and the Agricultural Performance in Nigeria in the Post Covid-19 Era: A Simulation Focus on Agricultural Output, Trade, and Employment
Authors: Akighir David Terfa , Kpoghul Emmanuel Tordue
Published: December 2022

The COVID-19 pandemic has unleashed negative economic consequences on the global economies and Nigeria inclusive. In response, Nigeria has launched the Economic Sustainability Plan (ESP) to leverage the potential gains of the African Continental Free Trade Area Agreement (AfCFTA) to accelerate agricultural performance in the post-COVID-19 era. Thus, this paper investigated the potential impact of AfCFTA on the performance of the agricultural sector in Nigeria in the post-COVID-19 era focusing on Agricultural output, trade and employment within the framework of a small macro-econometric model. The study used secondary data from 1970 to 2018 for a within-sample forecast and a twelve-year out-of-sample forecast spanning from 2019 to 2030. Two simulation experiments based on AfCFTA tariff reduction lines were conducted. Findings revealed that with tariff reduction under the AfCFTA, there is an increase in agricultural output, exports, employment, and the share of agriculture to GDP growth, as well as actual private consumption in Nigeria. The study concludes that if the AfCFTA is implemented, it will boost agricultural sector performance in Nigeria during the post-COVID-19 era. Based on these findings, the study recommended that the country implement mechanisms to overcome the challenges militating against agricultural production and exports in the economy to maximize the potential gains that AfCFTA provides. The government should also streamline its expenditures and invest hugely in infrastructural facilities such as roads, electricity, and expansion of sea-port facilities, communication networks and earth-dams to encourage dry-season farming activities.

Published: December 2022

The present paper investigates the association between outward FDI, exports and growth using data from 1990-2021. The novel estimation procedure of ARDL is used in the study to examine the long and short-run dynamics. Further, the causal relationship between outward FDI, exports and growth is also examined. The results imply that exports, OFDI, and economic growth in Bangladesh have a long-term cointegrating relationship. Additionally, FDI from abroad helps to increase the nation's exports. The study's conclusions are supported by the negative coefficient of the error-correcting term. The study provides useful insights for the policymakers of the country.
BEHAVIORAL INTENTION OF ISLAMIC PEER-TO-PEER LENDING SERVICES USERS
Authors: Kurniaputri Mega Rachma , Fatwa Nur
Published: December 2022

The fintech lending industry, as in non-bank financial institutions in Indonesia, has faced several problems, such as low financial literacy, constraints on the information system, weak scoring system, users data leakage, technology gaps with Islamic banks, and cases of default that make lenders disappointed and share it through social media. Although there are many problems, it does not reduce the intention of the lenders to lend their money through peer-to-peer lending as an alternative investment place. This research uses a quantitative descriptive method with the Partial Least Square - Structural Equation Modeling (PLS-SEM) technique. The study is conducted on 250 lenders in Indonesia who lend through Islamic peer-to-peer lending. Based on the results, lenders' intention is influenced by factors of effort expectancy, habit, and hedonic motivation. The lenders found that lending their money will improve their profit and make it easy to use. Meanwhile, facilitating conditions, habits, and behavioral intentions directly affect user behavior to continue to choose the Islamic peer-to-peer lending service that is already being used. The acceptance and use of lenders to use Islamic peer-to-peer lending are influenced by effort expectancy, habit, hedonic motivation, facilitating conditions, and behavioral intentions. This study is expected to be a recommendation for the financial technology industry to improve its services and facilities for users, particularly for lenders. In addition, this research can be an additional reference for regulators to make regulations related to Islamic financial technology, particularly for lenders in fintech lending.

Most of the serology was non-reactive IgG and IgM, followed was reactive IgG and the least was the reactive IgM.
 
ABSTRACT
Objective: To evaluate the serological description of the neonatal umbilical cord in COVID-19 mothers confirmed by RT-PCR at Rumah Sakit Umum Pusat (RSUP) H. Adam Malik Medan in January-June 2021.
Materials and Methods: This study was an observational study with a case series approach where the cases were mothers infected with SARS CoV-2 confirmed by RT-PCR. The study was conducted at Universitas Sumatera Utara (USU) Hospital Laboratory and RSUP H. Adam Malik for 6 months, from January 2021 to June 2021. The data collected were analyzed using descriptive statistics. If the data were normally distributed, they were presented as mean + SD; otherwise, they were presented as median (min-max) for each variable. The Statistical Package for Social Sciences version 22.0 (IBM SPSS Corp.; Armonk, NY, USA) was used for statistical analysis.
Results: Neonatal umbilical cord serology results (IgM and IgG) were predominantly non-reactive, where IgM was non-reactive in 43 neonates (97.7%) and IgG was non-reactive in 37 neonates (84.1%). In mothers without COVID-19 symptoms, neonate umbilical cord serology results were dominated by non-reactive IgM (88.6%) and IgG (79.5%). In mothers who recovered from COVID-19, neonate umbilical cord serology results were also dominated by non-reactive IgM (95.5%) and IgG (81.8%).
Conclusion: The neonatal umbilical cord serology results from the mother confirmed with positive COVID-19 were nonreactive IgG and IgM in the majority of 35 (79%) samples, reactive IgG in 7 (15.9%), and reactive IgM in 1 (2%) sample.

Published: December 2022

HIGHLIGHTS
1. This study reviews the effect of adequate levels of serum vitamin D on menstrual cycle2. Vitamin D affects the length and regularity of menstrual cycle3. Women with vitamin D insufficiency typically report irregular and prolonged menstrual periods than women with adequate vitamin D levels.
 
ABSTRACT
Objective: This study investigated the role of adequate vitamin D levels in the menstrual cycle of reproductive-age women.
Materials and Methods: We systematically searched using certain key words in PubMed and ScienceDirect for English articles, full articles, published between August 2013 - August 2022 that evaluated the effect of vitamin D levels on the menstrual cycle of women in reproductive age. The results were analyzed qualitatively.
Results: Eight studies from 653 recorded articles were eligible for review. Decreased vitamin D levels can cause menstrual cycle irregularities, which are related to a decrease in the hormone estradiol, affecting the menstrual cycle. In addition, lower levels of vitamin D lead to longer menstrual cycles.
Conclusion: Vitamin D is vital in the menstrual cycle because it influences the frequency and duration of menstruation.
Synthèse des principaux impacts de la dépoldérisation sur la biodiversité : une approche par revue systématique
Authors: DEBUE Marianne , OUEDRAOGO Dakis-Yaoba , SORDELLO Romain , REYJOL Yorick
Published: December 2022

Dans le cadre du programme Life Adapto, une revue systématique a été réalisée afin d’étudier les conséquences de la dépoldérisation sur la biodiversité. Cet article est une synthèse de la revue. Il dresse un bilan des caractéristiques des sites qui ont fait l’objet d’une dépoldérisation, notamment leur localisation, leur historique et la nature des opérations qui y sont menées. Les différents dispositifs expérimentaux mis en œuvre pour étudier une telle intervention sont également recensés, mettant en évidence que les études sont réalisées principalement sur le court terme et manquent parfois de rigueur dans l’application de dispositifs expérimentaux appropriés. La végétation est le taxon le plus étudié, contrairement aux mammifères, reptiles, amphibiens et microorganismes qui le sont plus rarement. De même, les suivis portent surtout sur des paramètres de composition (richesse spécifique, abondance) au détriment des données de structure (sex-ratio, âge des individus, etc.), et de fonction (fertilité, mortalité, etc.). Le travail de revue systématique a permis de mettre en évidence que la dépoldérisation s’accompagne généralement d’une diminution de la richesse spécifique végétale, et d’une augmentation de la richesse en invertébrés (macrocrustacés exceptés) et de l’abondance en poissons et des oiseaux limicoles. Plusieurs facteurs, de différentes natures (biotique, édaphique, anthropique, etc.), peuvent expliquer ces résultats.

All size data were acquired from Kutaraja, Aceh, and Sibolga, North Sumatra, as part of the enumeration program, courtesy of the Research Institute for Tuna Fisheries, from January 2016 to December 2020. The result showed that the skipjack stockâ€™s health is heading in an unsustainable direction. Further management actions are imminent to prevent any stock from declining shortly.Keywords: length-weight relationship, growth pattern, catch-at-size
A Numerical Investigation of Dimensionless Numbers Characterizing Meltpool Morphology of the Laser Powder Bed Fusion Process
Authors: Bhagat Kunal , Rudraraju Shiva
Published: December 2022

Microstructure evolution in metal additive manufacturing (AM) is a complex multi-physics and multi-scale problem. Understanding the impact of AM process conditions on the microstructure evolution and the resulting mechanical properties of the printed part is an active area of research. At the meltpool scale, the thermo-fluidic governing equations have been extensively modeled in the literature to understand the meltpool conditions and the thermal gradients in its vicinity. In many phenomena governed by partial differential equations, dimensional analysis and identification of important dimensionless numbers can provide significant insights into the process dynamics. In this context, a novel strategy using dimensional analysis and the method of linear least squares regression to numerically investigate the thermo-fluidic governing equations of the Laser Powder Bed Fusion AM process is presented in this work. First, the governing equations are solved using the Finite Element Method, and the model predictions are validated by comparing with experimentally estimated cooling rates, and with numerical results from the literature. Then, through dimensional analysis, an important dimensionless quantity - interpreted as a measure of heat ab- sorbed by the powdered material and the meltpool, is identified. This dimensionless measure of heat absorbed, along with classical dimensionless quantities such as Peclet, Marangoni, and Stefan numbers, is used to investigate advective transport in the meltpool for different alloys. Further, the framework is used to study the variations of thermal gradients and the solidification cooling rate. Important correlations linking meltpool morphology and microstructure evolution related variables with classical dimensionless numbers are the key contribution of this work.

Published: December 2022

Abstract: The aim of this study was to evaluate the effects of solids accumulation on greenhouse gas (GHG) emissions, substrate, plant growth and performance of a horizontal flow (HF) treatment wetland (TW) planted with Phragmites australis (Cav.) Trin. ex Steud. sub sp. australis. The study was carried out in an eight-year-old full-scale HF-TW located in the Mediterranean region (Sicily, Italy). To collect data inside the HF unit, nine observation points (besides the inlet and the outlet) along three 8.5 m long transects (T1, T2, and T3) were identified. The first transect (close to the inlet zone) showed hydraulic conductivity (Ks) reduction of about one order of magnitude higher than the other two. Results highlighted GHG emissions increasing during the summer when temperature and solar radiation were higher than in the rest of the year. Carbon dioxide (CO2) emis-sions decreased from T1 to T3, with maximum monthly values in T1 (21.4 g CO2 m-2 d-1) about double with respect to T2 (12.6 g CO2 m-2 d-1) and T3 (10.7 g CO2 m-2 d-1) observed in July. The CO2 seasonal trend was similar to that of P. Australis growth. Theoretical me-thane (CH4) emissions followed the trend of volatile solids (VS), which was about 3.5 and 4 times in T1 to T2 and T3. The highest CH4 emissions in T1 were probably due to anaerobic bacteria (methanogens) that proliferated in the waterlogged, anoxic part of TW. The pore-clogging affected the chemical oxygen demand (COD) removal efficiency which de-creasing from T1 to T3 for the observation period. Notwithstanding this behaviour, the final effluent quality was very satisfactory with the average value of COD removal efficiency above 90%.

The management of urban water has traditionally evolved from single-function systems to more sustainable perspectives promoting society and nature as inputs to engineer novel infrastructure. In the field of transdisciplinary research, co-design refers to a design thinking strategy in which people jointly frame a problem-solution. This article presents a conceptual framework to assess a case study focusing on the co-design and implementation of green infrastructure as a prototype for stormwater management. The evaluation is done from a self-reflective post-implementation perspective. Research activities are translated into the framework to evaluate conditions shaping the trajectory of the prototype. As result, key aspects driving the research concerning levels of stakeholders’ participation and dimensions of power are identified. Planning resilient co-design strategies to retrofit urban spaces is necessary to avoid unintended consequences, especially at the initial experimental stages. This study aims to contribute to the continuous improvement of pilot strategies in urban spaces by providing a framework for a structured evaluation of research experiences.

The promised dataset was obtained from the daily Turkish words and phrases pronounced by various people in the videos posted on YouTube. The purpose of collecting the dataset is to provide detection of the spoken word by recognizing patterns or classifying lip movements with supervised, unsupervised, semi-supervised learning and machine learning algorithms. Most of the datasets related with lip reading consist of people recorded on camera with fixed backgrounds and the same conditions, but the dataset presented here consists of images compatible with machine learning models developed for real-life challenges. It contains a total of 2335 instances taken from TV series, movies, vlogs, and song clips on YouTube. The images in the dataset vary due to factors such as the way people say words, accent, speaking rate, gender and age. Furthermore, the instances in the dataset consist of videos with different angles, shadows, resolution, and brightness that are not created manually. The most important feature of our lip reading dataset is that we contribute to the non-synthetic Turkish dataset pool, which does not have wide dataset varieties. Machine learning studies can be carried out in many areas, such as the defense industry and social life, with this dataset.

Published: December 2022

Garden strawberry is a valuable berry crop in Ukraine, the harmonious taste of its berries depends on the ratio of sugars and organic acids. Among the factors affecting the quantitative and qualitative composition of sugars and organic acids in berries, the area of cultivation and the pomological variety are distinguished. The article presents the results of studies of strawberry berries of Dukat, Honey and Polka varieties grown in the Right-Bank Forest-Steppe zone of Ukraine for the content and composition of sugars and organic acids using the methods of high-performance liquid chromatography on an Agilent Technologies chromatograph (model 1100) using a carbohydrate chromatographic column size 7,8×300 mm, "Supelcogel-C610H". It was found that the sugar content in strawberry berries of the Dukat, Honey and Polka varieties during the research period ranged from 5.0 to 8.6%. Berries of the Honey variety were distinguished by a significantly higher level of sugars – 8.6%. The content of reducing sugars in berries, according to the average data, was 4.9-7.7%. Among the investigated varieties, Polka berries had the lowest minimum amount of reducing sugars – 3.2%. The mass fraction of fructose was 2.1-4.4%, which is 42.0-51.1% of the sum of sugars, while glucose was 1.1-3.5% (22.0-40.7%) for a small amount of sucrose - 0.3-1.3, which is 6.0-15.1% of the total sugar content in berries. According to the results of the dispersion analysis, no significant influence of the pomological variety of berries on the content of reducing sugars was found. The mass fraction of organic acids in the berries of three strawberry varieties during the research period fluctuated within the limits 0.9-1.4% and significantly depended on the pomological variety of berries. The maximum amount of organic acids was found in Dukat berries - 1.4%. Organic acids in strawberries are represented by citric and malic acids with the dominance of citric acid – 57.0-68.1% of the total acid content. A higher level of citric acid was noted in strawberry berries of the Honey variety, while berries of the Ducat variety were distinguished by the level of apple acid. The sugar-acid index in all studied varieties of strawberry exceeded the value of 5.3, which made it possible to determine the taste of the berries as sweet and sour. In berries of the Dukat variety, it was lower due to the high content of organic acids.
Monthly Trends in Drug Overdose Mortality among Youth Aged 15-34 Years in the United States, 2018-2021: Measuring the Impact of the COVID-19 Pandemic
Authors: Lee Hyunjung , Singh Gopal K.
Published: December 2022

Background: Adolescents and young adults in the United States (US) have experienced a significant increase in drug overdose mortality rates in the last two decades. During the Coronavirus disease 2019 (COVID-19) pandemic, they experienced a lack of access to substance use disorder treatment, stay-home orders, school closure, social isolation, increased psychological distress, and financial strain. Few studies have examined the impact of the pandemic on monthly trends in drug-overdose mortality among youth by race/ethnicity. This study estimates differential changes in monthly drug overdose mortality among youth in the US by age, sex, and race/ethnicity.
Methods: Monthly deaths from the final 2018-2020 national mortality data and the 2021 provisional mortality data were used, and monthly population estimates were obtained from the Census Bureau. We calculated age-specific monthly drug overdose deaths per one million population and used log-linear regression models to estimate monthly percent increases in mortality rates from January 2018 through October 2021.
Results: Drug-overdose deaths among individuals aged 15-34 increased by 36.5% from 2019 (21,152 deaths) to 2020 (28,879 deaths). From February 2020 to May 2020, the drug-overdose mortality rate increased by 62% for males, 53% for females, 79% for Blacks, 62% for American Indians/Alaska Natives (AIANs), 57% for Hispanics, 56% for non-Hispanic Whites, and 47% for Asians. From January 2018 to October 2021, the average monthly drug-overdose mortality rate increased by 2.69% per month for Blacks, 2.54% for AIANs, 2.27% for Hispanics, 1.37% for Asians, and 0.81% for non-Hispanic Whites. Increases in drug-overdose mortality were more rapid among males than females and among youth aged 15-24 than youth aged 25-34.
Conclusion and Global Health Implications: During the peak months in 2020 and 2021, the COVID-19 pandemic had a disproportionate impact by race/ethnicity on trends in drug overdose mortality among the youth. Drug overdose mortality rates increased faster among Blacks, Hispanics, AIANs, and Asians compared to non-Hispanic Whites.

Marked Disparities in COVID-19 Vaccination among US Children and Adolescents by Racial/Ethnic, Socioeconomic, Geographic, and Health Characteristics, United States, December 2021 – April 2022
Authors: Singh Gopal K , Lee Hyunjung , Azuine Romuladus E.
Published: December 2022

Background: The COVID-19 pandemic has had a substantial adverse impact on the health and well-being of populations in the United States (US) and globally. Although COVID-19 vaccine disparities among US adults aged ≥18 years are well documented, COVID-19 vaccination inequalities among US children are not well studied. Using the recent nationally representative data, we examine disparities in COVID-19 vaccination among US children aged 5-17 years by a wide range of social determinants and parental characteristics.
Methods: Using the US Census Bureau’s Household Pulse Survey from December 1, 2021 to April 11, 2022 (N=86,335), disparities in child vaccination rates by race/ethnicity, socioeconomic status, health insurance, parental vaccination status, parental COVID-19 diagnosis, and metropolitan area were modeled by multivariate logistic regression.
Results: During December 2021–April 2022, an estimated 40.1 million or 57.2% of US children aged 5-17 received COVID-19 vaccination. Vaccination rates were lowest among children of parents aged 25-34 (34.9%) and highest among children of parents aged 45-54 (69.2%). Children of non-Hispanic Black parents, divorced/separated and single individuals, parents with lower education and household income levels, renters, not-employed parents, the uninsured, and parents without COVID-19 vaccination or with COVID-19 diagnoses had significantly lower rates of vaccination. Controlling for covariates, Asian and Hispanic children aged 5-17 had 134% and 47% higher odds of receiving vaccination than their non-Hispanic White counterparts. Children of parents with a high school education had 47% lower adjusted odds of receiving vaccination than children of parents with a master’s degree or higher. Children with annual household income <$25,000 had 48% lower adjusted odds of vaccination than those with income ≥$200,000. Although vaccination rates were higher among children aged 12-17 than among children aged 5-11, sociodemographic patterns in vaccination rates were similar. Parental vaccination status was the strongest predictor of children’s vaccination status Vaccination rates for children aged 5-17 ranged from 49.6% in Atlanta, Georgia to 82.6% in San Francisco, California.
Conclusion and Global Health Implications: Ethnic minorities, socioeconomically-disadvantaged children, uninsured children, and children of parents without COVID-19 vaccination or with COVID-19 diagnoses had significantly lower vaccination rates. Equitable vaccination coverage among children and adolescents is critical to reducing inequities in COVID-19 health outcomes in the US and globally.
