The current situation on bovine leukemia in Dagestan and methods of its diagnosis

The article presents the current situation on bovine leukemia in the municipalities of Dagestan and a comparative analysis of serological and molecular-genetic methods of diagnosis. In municipal districts, urban districts and areas of animal husbandry for the first half of 2022, the number of animals examined by immune diffusion 531111 identified 2871, infected with the leukemia virus, which is 0,5 % from the number diagnosed. The degree of infection of livestock with bovine leukemia virus in rural areas varied from 0,01 to 5,2 %. The average coverage rate of serological studies of animals on leukemia – 57,2 %. Hematological studies of seropositive animals were not carried out during the analyzed period. 79 new leukemia-affected points have been registered, 95 unhealthy points have been transferred since 2021, only 3 points have been rehabilitated. As on 01.07.2022, 171 leukemia-affected points are registered, including 38 in agricultural enterprises, 4 of them in breeding farms, 27 farms and 106 farms. A comparative analysis of the data on the carrier of antibodies and DNA provirus showed that ELISA revealed 7 animals more carriers of antibodies than in AGID, PCR study revealed 14 and 7 animals more carriers of DNA provirus than carriers of antibodies in AGID and ELISA, respectively. To maximize the detection of seropositive BLV of animals, the integrated use of AGID, ELISA and PCR methods as a promising system in anti-leukemia measures is proposed. The introduction of ELISA and PCR diagnostics into the veterinary practice of the Dagestan Republic will make it possible to determine virus transmission in animals from the first day after birth (ELISA) and from the 20th day of the calf's life (PCR), as well as to increase the effectiveness and shorten the duration of anti-leukemia measures the final stages of the recovery of agricultural enterprises from leukemia infection.

Role of vermicomposting for smallholder farmers in wondo-genet woreda, Sidama region, Ethiopia: a success story

Both organic and chemical fertilizers play a vital role in enhancing crop productivity and maintaining soil health. However, inflated prices of chemical fertilizers also reduced their rate of application, hence, reducing crop productivity in Ethiopia. Therefore, to sustain the productivity of lands and crops, there is an urgent need to promote the use of organic fertilizers. Vermicomposting is one method of preparing enriched compost with the use of earthworms. With the support of the second phase of the Agricultural Growth Program (AGP-II), the introduction and promotion of vermicomposting technology were conducted. However, the production status and role of vermicomposting for smallholder farmers in the area are unclear. Therefore documenting the achievement and progress of vermicomposting is necessary. Both primary and secondary data (2018-2021) were collected by using snowball sampling techniques. The descriptive statistics reveal that in addition to potato production, farmers are using vermicompost for chat, enset, coffee, forage and vegetable production. Accordingly, the production, utilization, and sale trend of vermicompost increased from 2018 to 2021. In addition, vermicomposting created an opportunity for farmers to participate in earthworms and vermicompost selling. Due to this, those who had vermicompost in their home garden do not use inorganic fertilizers for any crop production during the last four years. In addition, the average cultivated cropland coverage by vermicompost-based production also increased from 2018 to 2021. Its preparation procedure is also consistent with the manual provided to them. Therefore expanding vermicomposting technology in the area has the potential to enhance sustainable crop and land productivity. Int. J. Agril. Res. Innov. Tech. 12(2): 88-95, December 2022

Determinants of continuum of care for maternal, newborn, and child health services in Ethiopia: Analysis of the modified composite coverage index using a quantile regression approach.

Maternal and child mortality remain unacceptably high in the Sustainable Development Goals era. Continuum of care has become a key strategy for improving the health of mothers and newborns. Previous research on the continuum of care in Ethiopia is often limited to maternal health services. Maternal and child health services are inseparably linked, and an integrated approach to care is essential. This study assessed the continuum of maternal, newborn, and child health care and associated factors in Ethiopia. The analysis was based on the 2016 Ethiopian Demographic and Health Survey data. We restricted our analysis to women with their most recent children-alive and living with their mother- aged 12-23 months at the time of the survey (n = 1891). The modified composite coverage index, constructed from twelve maternal and child health services, was calculated as an indicator of the continuum of care. Bivariable and multivariable quantile regression were used to analyse the relationship between the predictors and specific quantiles of the composite coverage index. The effect of each variable was examined at the 10th, 25th, 50th, 75th, and 95th quantiles. The results showed that the average composite coverage index value was 39%. The overall completion rate of the continuum of care was low (2%). Four % of the women did not receive any of the services along the continuum of care. Postnatal care for newborns had the lowest coverage (12%). This study provides evidence that factors such as the educational status of women, region, residence, socio-economic status, perceived distance to a health facility, pregnancy intention, mode of delivery, parity, and early antenatal care initiation influence the continuum of care differently across levels of the composite coverage index. The findings call for integrated and targeted strategies that aim to improve the continuum of care considering the determinants.

Design of an Intermittent Herbicide Spray System for Open-Field Cabbage and Plant Protection Effect Experiments

To address the problem of herbicide residues exceeding the safety standard due to continuous spraying of herbicides on open-field cabbage, we propose an intermittent weed spraying control method integrating cabbage position, cabbage canopy size, and spraying machine operation speed. It is based on an early-stage cabbage target identification method obtained in the early stage and the operation requirements in open-field cabbage. Built with a C37 controller, a stable pressure spray system and an intermittent weed spraying control system for open-field cabbage, an integrated system was designed. Experimental verification was carried out through measurement indexes such as spraying precision, herbicide saving rate, herbicide efficacy, and herbicide residue. Since the industry is faced with a status quo of a lack of relevant operational norms and national standards for the precise weed spraying operation mode, this paper provides a relatively perfect experiment and evaluation method for this mode. The experimental results on the accuracy of weed spraying at different speeds showed that the mean absolute error (MAE), root mean square error (RMSE), and average spray cabbage coverage rate (ASCCR) of intermittent weed spraying increased, but the average effective spray coverage rate (AESCR) decreased with increasing operation speed. When the working speed was 0.51 m/s, the MAE and RMSE of intermittent weed spraying were less than 2.87 cm and 3.40 cm, respectively, and the AESCR was 98.4%, which verified the feasibility of operating the intermittent weed spraying of cabbage. The results of a field experiment showed that the average weed-killing rate of intermittent weed spraying for open-field cabbage was 94.8%, and the herbicide-saving rate could reach 28.3% for a similar weeding effect to that of constant-rate application, which not only met the needs of intermittent weed spraying in open-field cabbage but also had great significance for improving the herbicide utilization rate. Compared with the constant-rate application method, the herbicide residue concentration detected using intermittent weed spraying for cabbage decreased by 66.6% on average, which has important research significance and application value for ensuring the normal growth of crops and the safety of agricultural products.

Conformal asymmetric multi-quantile generative transformer for day-ahead wind power interval prediction

With the rapid increase in the installed capacity of wind power, day-ahead wind power interval prediction is becoming more and more important. To solve such a challenging problem and provide intervals of higher quality, this paper proposes a prediction method based on conformal asymmetric multi-quantile generative transformer. Herein, the multi-quantile generative transformer is a deep learning model that generates multi-quantile forecast results for next day through one forward propagation process. Then, two quantiles, whose width is the smallest while satisfying the nominal confidence constraint, are selected from the predicted sequence as the upper bound and lower bound of the asymmetric interval. Furthermore, we introduce the conformal quantile regression to calibrate the bounds of the prediction interval to ensure that its coverage rate is as close as nominal confidence. The experiments show that the proposed method surpasses the benchmarks by providing narrower prediction intervals with more accurate empirical coverage probability. Under nominal confidence 90%, it gives prediction intervals with average empirical coverage probability of 90.50% and normalized average width of 0.44 on four wind farms. Compared with symmetric prediction intervals given by common benchmark quantile long short term memory network, the average width is reduced by 19.6%.

Changes in Radiologists' Gaze Patterns Against Lung X-rays with Different Abnormalities: a Randomized Experiment.

The workload of some radiologists increased dramatically in the last several, which resulted in a potentially reduced quality of diagnosis. It was demonstrated that diagnostic accuracy of radiologists significantly reduces at the end of work shifts. The study aims to investigate how radiologists cover chest X-rays with their gaze in the presence of different chest abnormalities and high workload. We designed a randomized experiment to quantitatively assess how radiologists' image reading patterns change with the radiological workload. Four radiologists read chest X-rays on a radiological workstation equipped with an eye-tracker. The lung fields on the X-rays were automatically segmented with U-Net neural network allowing to measure the lung coverage with radiologists' gaze. The images were randomly split so that each image was shown at a different time to a different radiologist. Regression models were fit to the gaze data to calculate the treads in lung coverage for individual radiologists and chest abnormalities. For the study, a database of 400 chest X-rays with reference diagnoses was assembled. The average lung coverage with gaze ranged from 55 to 65% per radiologist. For every 100 X-rays read, the lung coverage reduced from 1.3 to 7.6% for the different radiologists. The coverage reduction trends were consistent for all abnormalities ranging from 3.4% per 100 X-rays for cardiomegaly to 4.1% per 100 X-rays for atelectasis. The more image radiologists read, the smaller part of the lung fields they cover with the gaze. This pattern is very stable for all abnormality types and is not affected by the exact order the abnormalities are viewed by radiologists. The proposed randomized experiment captured and quantified consistent changes in X-ray reading for different lung abnormalities that occur due to high workload.

PPNet: Identifying Functional Association Networks by Phylogenetic Profiling of Prokaryotic Genomes.

Identification of microbial functional association networks allows interpretation of biological phenomena and a greater understanding of the molecular basis of pathogenicity and also underpins the formulation of control measures. Here, we describe PPNet, a tool that uses genome information and analysis of phylogenetic profiles with binary similarity and distance measures to derive large-scale bacterial gene association networks of a single species. As an exemplar, we have derived a functional association network in the pig pathogen Streptococcus suis using 81 binary similarity and dissimilarity measures which demonstrates excellent performance based on the area under the receiver operating characteristic (AUROC), the area under the precision-recall (AUPR), and a derived overall scoring method. Selected network associations were validated experimentally by using bacterial two-hybrid experiments. We conclude that PPNet, a publicly available (https://github.com/liyangjie/PPNet), can be used to construct microbial association networks from easily acquired genome-scale data. IMPORTANCE This study developed PPNet, the first tool that can be used to infer large-scale bacterial functional association networks of a single species. PPNet includes a method for assigning the uniqueness of a bacterial strain using the average nucleotide identity and the average nucleotide coverage. PPNet collected 81 binary similarity and distance measures for phylogenetic profiling and then evaluated and divided them into four groups. PPNet can effectively capture gene networks that are functionally related to phenotype from publicly prokaryotic genomes, as well as provide valuable results for downstream analysis and experiment testing.

Growth characteristics and the mass transfer mechanism of single bubble on a photoelectrode at different electrolyte concentrations.

In the photoelectrochemical water splitting reaction, the bubble attached to the working electrode is an essential factor affecting the reaction resistance, current density and gas-liquid mass transfer. An experimental measurement system based on an electrochemical workstation synchronously coupled with a high-speed microscopic camera was proposed and used to systematically study the growth kinetics and mass transfer mechanism of single oxygen bubbles at different electrolyte concentrations (Na2SO4, 0.1-2.0 M) on the TiO2 photoanode surface. Under constant voltage and constant current control conditions, when the electrolyte concentration increases, the bubble detachment diameter and the bubble detachment frequency gradually decrease. The bubble coverage equation expressed in terms of gas evolution efficiency is proposed and is associated with the photocurrent and bubble radius. The average bubble coverage and average gas evolution efficiency decrease when the electrolyte concentration is increased. According to the Sherwood dimensionless number, various mass transfer coefficients during bubble growth were calculated. The results show that the average total mass transfer coefficient is positively correlated with the change trend of the electrolyte concentration, and the mass transfer coefficient of single-phase natural convection is one order of magnitude larger than the mass transfer coefficient of bubble-induced convection. Finally, a conclusion on the transient mass transfer process in the bubble evolution process was obtained, that is, the mass transfer coefficient of single-phase natural convection and the total mass transfer coefficient remain high during the first growth stage, and gradually decrease during the second growth stage. Therefore, regulating the electrolyte concentration can effectively promote the gas-liquid mass transfer in the photoelectrochemical water splitting reaction.

Abstract IA024: Single nuclei chromatin accessibility and transcriptomic map of breast tissues of women of diverse genetic ancestry

Abstract Single nuclei analysis is allowing robust classification of cell types in an organ that helps to establish relationships between cell-type specific gene expression and chromatin accessibility status of gene regulatory regions. Using the institutional resource of breast tissues of healthy donors of various genetic ancestry, we have developed a comprehensive chromatin accessibility (snATAC-seq) and gene expression (snRNA-seq) atlas of human breast tissues. Our analyses included 51,367 nuclei with average sequence coverage of 1195 genes per nuclei. These nuclei were derived from 22 donors of Ashkenazi descent, 20 of European non-Ashkenazi ancestry, 10 of Asian ancestry, 10 Hispanic/Latina, 10 Native American, 6 from BRCA1 mutation carriers, and 5 from BRCA2 mutation carriers. Although tissues from 20 women of African Ancestry were included in sequencing, poor quality sequencing reads prevented inclusion of data from those samples in the final analysis. Integrated analysis revealed 10 distinct cell types in the healthy breast, which included three major epithelial cell subtypes (mature luminal, luminal progenitor, basal), two endothelial subtypes, two adipocyte subtypes, fibroblasts, T-cells, and macrophages. Mature luminal cells could be further divided into two distinct hormone sensitive subtypes, HSa and HSb, with HSa subtype expressing higher levels of Estrogen Receptor alpha (ESR1) and NEK10, a tyrosine kinase that controls p53 activity and limits cell proliferation. The luminal progenitors could be broadly classified into alveolar progenitors (AP) and basal-luminal hybrid progenitors (BL). AP cells expressed higher levels of ELF5, a known marker of alveolar cells, compared to BL cells. Basal cells could be classified into two subtypes with Basal-BAa cells being the most dominant and expressing higher levels of TP63 and NFIB compared to Basal-BAb cells. ESR1 expression pattern was distinctly different in tissues from Native Americans compared to the rest, with a high level of ESR1 expression extending to AP cells. In fact, overall AP cell numbers were ~3-fold higher in Native Americans compared to others (18.9% versus 1.5-8.8%). Furthermore, Ingenuity pathway analysis of differentially expressed genes revealed elevated Estrogen Receptor signaling in ML and AP cell types of Native Americans compared to those of other genetic ancestry. Despite significant differences in expression and activity in Native Americans compared to others, the chromatin accessibility map of the ESR1 gene regulatory regions in ML and LP cells did not show any genetic ancestry dependent variability. In general, cell subtype-specific gene expression did not correlate with chromatin accessibility differences, suggesting that transcriptional regulation independent of chromatin accessibility governs cell type-specific gene expression in the breast. Collectively, these results reveal complexities in gene expression in different cell types of the breast Citation Format: Poornima Bhat-Nakshatri, Duojiao Chen, Aditi Khatpe, Hongyu Gao, Yunlong Liu, Anna Maria Storniolo, Harikrishna Nakshatri.

Research on Fire Alarm System Based on Entropy Power Method and Topsis Superiority and Inferiority Solution Distance Method

According to the statistics of China Fire and Rescue Bureau, in 2021, 748,000 fires were reported to the national fire and rescue teams, with 1,987 deaths, 2,225 injuries and direct property losses of 6.75 billion yuan. The loss of these innocent lives and the loss of a large amount of property make us think while deploring: is there a more effective, scientific and accurate way to prevent the great harm caused by the occurrence of fire. The fire alarm system studied in this paper can be used to reduce the hazards. Firstly, the number of real fires is given 430 times by using three indicators of fire occurrence: address, machine number and loop. After selecting the high-frequency parts in the loop, machine number and component type respectively and finding their corresponding false alarm rate and failure rate, the evaluation weights are obtained using the entropy weight method. A comprehensive evaluation model based on the entropy weight method is established to score each major component. Two most reliable components of the fire alarm system are obtained: the intelligent photoelectric probe and the manual alarm button. Next, the normalized management level of each fire brigade needs to be analyzed. First, the five important parameters of normalized average coverage rate, normalized component reliability, normalized component failure rate, normalized jurisdictional fire frequency (times/hour), and normalized false alarm rate are derived for each fire brigade. The comprehensive score index of each brigade was derived and ranked by the Topsis superiority and inferiority solution distance method, and it was concluded that M brigade, L brigade, and F brigade were the three jurisdictions with the lowest comprehensive management level.

Profiling PIK3CA variants in disorders of somatic mosaicism

PurposeVariants in PIK3CA (encoding p110α; the catalytic subunit of PI3K) characterize some disorders of somatic mosaicism (DoSM) conditions with clinical features, including sporadic overgrowth and vascular malformations. Here, we profile PIK3CA variants in DoSM. MethodsWe applied a next-generation, sequencing-based, laboratory-developed test, using an average coverage of approximately 2000× for up to 37 genes associated with DoSM, on a cohort of 1197 patients with DoSM referred for clinical genomics services between 2013 and 2022. ResultsWe identified clinically reportable variants in 747 (62.4%) individuals in this cohort. Notably, 371 clinically reportable variants in PIK3CA were identified in 368 patients, constituting approximately 49.2% of all patients with reportable findings. Variants in the C2 domain of p110α are enriched in DoSM (this cohort) compared with those of cancer (Catalogue of Somatic Mutations in Cancer [COSMIC] database), highlighting the role of the C2 domain in driving uncontrolled cell proliferation in DoSM. Furthermore, we report 17 novel variants in PIK3CA that are not previously reported in DoSM and describe clinical presentation correlation for 4 novel variants. ConclusionOur findings from the largest single-center cohort of patients with DoSM expand the spectrum of variants in PIK3CA and shed light on the less-studied role of the C2 domain in the pathogenesis of DoSM.

Forecasting with a panel Tobit model

We use a dynamic panel Tobit model with heteroskedasticity to generate forecasts for a large cross‐section of short time series of censored observations. Our fully Bayesian approach allows us to flexibly estimate the cross‐sectional distribution of heterogeneous coefficients and then implicitly use this distribution as prior to construct Bayes forecasts for the individual time series. In addition to density forecasts, we construct set forecasts that explicitly target the average coverage probability for the cross‐section. We present a novel application in which we forecast bank‐level loan charge‐off rates for small banks.

A method for personalised music recommendation based on emotional multi-label

In this paper, a personalised music recommendation method based on emotion multi-label was proposed. First is the analysis of music emotion and music emotional label, then, the principal component analysis method is used to reduce the dimension to process the music features and complete the preprocessing. Secondly, construct the music emotion multi-label, and combine the cosine method to calculate the emotional multi-label similarity. Finally, the interest degree of emotional multi-label is calculated to obtain the user's interest degree of music resources, and the personalised recommendation method is optimised to realise the personalised recommendation of music. Experimental results show that the average coverage rate of personalised music recommendation of the proposed method is as high as 99.5%, the accuracy is 98.3%, and the recommendation time of 500 music items is only 18.9 s. Therefore, the recommendation effect of the proposed method is good, the accuracy of personalised music recommendation is improved, and the recommendation time is shortened.

Spray Deposition and Distribution on Rice as Affected by a Boom Sprayer with a Canopy-Opening Device

In China, rice growers predominantly use boom sprayers. However, boom sprayers have several drawbacks related to poor penetration in the middle and late stages of rice growth. Several studies have shown that the use of the canopy-opening device can improve droplet deposition in the middle and under layers of rice. Some growers doubt the efficacy of canopy-opening boom sprayers, whereas others have questions about their use. This study aimed to address both doubts and questions by evaluating the effect of spraying rice using a canopy-opening device and a canopy-opening divider combination device. The tested rice variety was “Longliangyou 2010”. Three different boom sprayers were evaluated for this purpose: (1) a boom sprayer with a canopy-opening device, (2) a boom sprayer with a canopy-opening divider combination device, and (3) a traditional boom sprayer. The effects of the position of the canopy-opening device and the spraying velocity on the deposition of droplets were considered. The experiments showed that the droplet coverage was significantly affected by boom sprayers, the position of the canopy-opening device, the spraying velocity, and the interaction of the position of the canopy-opening device and the spraying velocity. Under the spraying distance of 60 cm from the rice root and the spraying velocity of 1.2 m s−1, the spraying coverage of the paraxial surface of the whole canopy was higher than that of other treatment conditions when the canopy opening device was used. The positive spraying coverage rates of the upper, middle and lower layers were 95.18%, 88.41% and 94.99%, respectively. Compared with the traditional boom sprayer, the use of the canopy-opening device increased the average droplet coverage on the adaxial surface canopy by more than 72.91% and the average droplet coverage on the abaxial surface canopy by more than 6.88%.

The complete mitochondrial genome of Sporophila nigricollis (Aves, Passeriformes).

Sporophila nigricollis, popularly known as Yellow-bellied Seedeater, is a commonly trafficked bird in Brazil. This study describes the complete mitogenome of the species and its phylogenetic position. DNA sample was sequenced on MiSeq (Illumina®) sequencer. Reads were assembled to reference using Geneious. A total of 11,740 paired sequence reads were used to produce the complete mitochondrial DNA sequence with average coverage of 176x. The mitogenome was found to be circular in shape and consisted of 16,777 base pairs. The mitochondrial genome was annotated with MITOS and verified with ExPASy. Its structure contains two ribosomal RNA (rRNA) genes, 22 transporter RNA (tRNA) genes, 13 protein-coding genes (PCGs) and one control region. Twelve of the 13 PCGs have ATG as start codon. Seven of the 13 PCGs contain a TAA stop codon. Most of the tRNA genes and PCGs are encoded on the heavy strand. Phylogenetic analyses were conducted with MEGA using the maximum likelihood method. Sporophila nigricollis grouped together with other Thraupidae species. This study presents the first complete mitogenome of Sporophila nigricollis and can be useful for research on evolution, ecology and conservation of this species.

Ecosystem Functioning of the Loess Plateau in China from Vegetation Restoration Relied Largely on Climate

Climate change and anthropogenic replantation are supposed to greatly change vegetation coverage and ecosystem stability and functions, e.g., net primary productivity (NPP), evapotranspiration (ET) and water use efficiency (WUE). Our study compared WUE of nature- and human-induced forest cover increase on the Loess Plateau since 2000 using satellite-derived Vegetation Continuous Fields (VCF), NPP, ET. This study also applied over 30 years of model-based NPP and meteorological observations to compare the stability and changes brought up by the Grain for Green Project. The result showed that the average forest coverage fraction increased from 7.1% (~4.5 × 104 km2) in 2000 to 11.2% (~7.3 × 104 km2) in 2014. Artificial forest cover increase occupied 76.43% of the significantly increasing tree cover regions. The role of revegetation practice in NPP and ET became gradually more dominant than climate factors in artificial forests from the northern to the southern part of the Loess Plateau. For areas experiencing limited forest coverage increase, artificial forest areas showed higher WUE than natural forest areas under similar mean annual precipitation (MAP). The difference in stability was small between neighboring natural and artificial forest areas. The northwest of the Loess Plateau had an increasing resilience, whereas the south of the Plateau had an increased resistance to precipitation and temperature change. The higher dependency of the northern reforested areas on climate fluctuation indicates a growing threat of water scarcity to the sustainability of anthropogenic reforestation in semi-arid regions.

Tetanus, Diphtheria, and Acellular Pertussis Vaccination Coverage Among Publicly Insured Pregnant Women, U.S., 2016–2019

Vaccination with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine during pregnancy is highly effective against Bordetella pertussis in young infants. We aimed to evaluate the uptake of maternal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccination during the recommended gestation period of 27 through 36 weeks among women enrolled in a public medical insurance plan in the U.S. In this analysis using Centers for Medicare and Medicaid Services insurance claims data, we identified women aged 15 through 49 years who delivered a live-born infant from 2016 through 2019. We identified claims for tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccination to calculate the proportion of women who were vaccinated during Weeks 27 through 36 of gestation in each calendar year. We also assessed the average annual maternal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis coverage by age group, race and ethnicity, U.S. Census region of residence, and plan type. Data were analyzed in 2021. Among 4,318,823 deliveries, the 4-year national average for tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccination was 26%, improving from 22% in 2016 to 31% in 2019 (p<0.001). Within subgroups, the lowest 4-year average coverage was among women aged 15 through 18 years (22%); Black, non-Hispanic (23%) and Hispanic women (24%); those residing in the South (18%); those enrolled in a Children's Health Insurance Program plan (22%); and those covered by a fee-for-service plan (19%). Coverage increased across all subgroups from 2016 through 2019. Although maternal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis coverage among publicly insured women in the U.S. increased from 2016 through 2019, it remained considerably lower than estimated national coverage, with notable differences by race and ethnicity.
