Estimation of the poliovirus type 2 immunity gap in South Africa.

In the context of polio eradication efforts, accurate assessment of vaccination programme effectiveness is essential to public health planning and decision making. Such assessments are often based on zero-dose children, estimated using the number of children who did not receive the first dose of the Diphtheria-Tetanus-Pertussis containing vaccine as a proxy. Our study introduces a novel approach to directly estimate the number of children susceptible to poliovirus type 2 (PV2) and uses this approach to provide district-level estimates for South Africa of susceptible children born between 2017 and 2022. We used district-level data on annual doses of inactivated poliovirus vaccine (IPV) administered, live births, and population sizes, from 2017 through 2022. We imputed missing vaccination data, implemented flexible assumptions regarding dose distribution in the eligible population, and used estimated efficacy values for one, two, three, and four doses of IPV, to compute the number of susceptible and immune children by birth year. We validated our approach by comparing an intermediary output with zero-dose children (ZDC) estimated using data reported by WHO/UNICEF Estimates of National Immunization Coverage (WUENIC). Our results indicate high heterogeneity in susceptibility to PV2 across South Africa's 52 districts as of the end of 2022. In children under 5 years, PV2 susceptibility ranged from approximately 30 % in districts including Xhariep (31.9 %), Ekurhuleni (30.1 %), and Central Karoo (29.8 %), to less than 4 % in Sarah Baartman (1.9 %), Buffalo City (2.1 %), and eThekwini (3.2 %). Our susceptibility estimates were consistently higher than ZDC over the timeframe. We estimated that ZDC decreased nationally from 155,168 (152,737-158,523) in 2017 to 108,593 in 2021, and increased to 127,102 in 2022, a trend consistent with ZDC derived from data reported by WUENIC. While our approach provides a more comprehensive profile of PV2 susceptibility, our susceptibility and ZDC estimates generally agree in the ranking of districts according to risk.

Adverse events following immunization of co- and separate administration of DTaP-IPV/Hib vaccines: A real-world comparative study.

To fully understand the safety of DTaP-IPV/Hib vaccination, we evaluated the differences between DTaP-IPV/Hib co-administration and separate administration of the DTaP, IPV and Hib vaccines (DTaP+IPV+Hib) based on adverse events following immunization (AEFI). All AEFI reported in Hebei Province, China, between 2020 and 2022 were included in this study. The risk difference (RD%), relative risk (RR), and Chi-square value were used to compare the differences in reported rates of AEFI between the DTaP-IPV/Hib and DTaP+IPV+Hib groups. From 2020 to 2022, 130 AEFI cases were reported in Hebei Province after DTaP-IPV/Hib vaccination, corresponding to an AEFI reported rate of 66.9/million doses, which was significantly lower than that for DTaP+IPV+Hib (9836 AEFI with a reported rate of 637.8/million doses). The overall reported rate of non-severe AEFI for DTaP+IPV+Hib vaccines was 9.5 times that of DTaP-IPV/Hib vaccination [95% confidence interval (CI): 8.0, 11.3]. Meanwhile, the reported rate of AEFI among infants aged 0-1 y was 9.8 times higher for DTaP+IPV+Hib than for DTaP-IPV/Hib (95% CI: 8.2, 11.7). DTaP+IPV+Hib vaccination also resulted in higher risks of high fever, localized redness and swelling, localized induration, and allergic rash compared with DTaP-IPV/Hib vaccination. The risk of AEFI, which were mostly mild reaction, was higher after vaccination with DTaP+IPV+Hib than after DTaP-IPV/Hib vaccination.

Immunogenicity and Safety of a Quadrivalent Meningococcal Conjugate Vaccine Versus Nimenrix in Healthy Adolescents: A Randomized Phase IIIb Multicenter Study.

INTRODUCTION: Many immunization programs in Europe recommend quadrivalent meningococcal vaccinations, which are often administered concomitantly with other vaccines. We compared the immune response of a tetanus toxoid conjugated quadrivalent meningococcal vaccine (MenACYW-TT, MenQuadfi®) with another quadrivalent meningococcal conjugate vaccine (MCV4-TT; Nimenrix®) when administered alone or concomitantly with Tdap-IPV and 9vHPV vaccines in adolescents. METHODS: In this phase IIIb trial, healthy adolescents (MenC-naïve or MenC-primed before 2 years of age) from Spain, Italy, Hungary, and Singapore were randomized in a 3:3:2 ratio to receive either MenACYW-TT or MCV4-TT alone, or MenACYW-TT concomitantly with 9vHPV and Tdap-IPV. The primary objective was to demonstrate the non-inferiority of the seroprotection rate (human serum bactericidal assay [hSBA] titer ≥ 1:8) to serogroups A, C, W, and Y 30 days post-vaccination with a single dose of MenACYW-TT or MCV4-TT. Secondary objectives included describing hSBA titers for the four serogroups before and 1 month following vaccination and according to MenC priming status. RESULTS: A total of 463 participants were enrolled (MenACYW-TT, n = 173; MCV4-TT, n = 173; MenACYW-TT/9vHPV/Tdap-IPV n = 117). Non-inferiority based on seroprotection was demonstrated for MenACYW-TT versus MCV4-TT for all serogroups. Immune responses were comparable whether MenACYW-TT was administered alone or concomitantly with Tdap-IPV and 9vHPV. Post-vaccination hSBA GMTs were higher in MenACYW-TT vs. MCV4-TT for serogroups C, Y, and W and comparable for serogroup A. The percentages of participants with an hSBA vaccine seroresponse were higher in MenACYW-TT vs. MCV4-TT for all serogroups. For serogroup C, higher GMTs were observed in both MenC-naïve or -primed participants vaccinated with MenACYW-TT vs. MCV4-TT. Seroprotection and seroresponse were higher in MenC-naïve participants vaccinated with MenACYW-TT vs. MCV4-TT and comparable in MenC-primed. The safety profiles were comparable between groups and no new safety concerns were identified. CONCLUSIONS: These data support the concomitant administration of MenACYW-TT with 9vHPV and Tdap-IPV vaccines in adolescents. TRIAL REGISTRATIONS: Clinicaltrials.gov, NCT04490018; EudraCT: 2020-001665-37; WHO: U1111-1249-2973.

MenACYW conjugate vaccine has been made to protect against meningococcal disease caused by four common types of bacteria (germs) called Neisseria meningitidis (or meningococcus), A, C, W, and Y. Many people, particularly adolescents, have the germs of this disease in their nose or throat, and therefore may develop the disease or transmit the bacteria to other people. Hence, adolescent meningococcal vaccination against serogroups ACWY is increasingly recommended in several countries. This study assessed the immune response to these serogroups in healthy adolescents after one dose of MenACYW conjugate vaccine or Nimenrix^®, a meningococcal licensed vaccine. Moreover, the immune response and safety were assessed when the vaccines were given alone or when given concomitantly with other adolescent vaccines, including the human papillomavirus (9vHPV) and tetanus, diphtheria, pertussis, and poliomyelitis (Tdap-IPV) vaccines. A total of 463 adolescents (aged 10­17 years) participated in this study and received either MenACYW or Nimenrix^® alone, or MenACYW concomitantly with 9vHPV and Tdap-IPV vaccine. The immune response induced by MenACYW was as good as the immune response induced by Nimenrix^®, and when given alone or concomitantly with 9vHPV and Tdap IPV vaccines. None of the participants experienced any serious side effects of any vaccine. The most common non-serious side effects were injection site pain, muscle pain, and headache. These data support the use of MenACYW in adolescents, with or without concomitant administration with 9vHPV and Tdap-IPV, which may help to increase the number of adolescents vaccinated.

Physical and psychological health consequences of intimate partner violence among married primary school teachers in Delta South Senatorial Zone of Delta State, Nigeria: Implication for marital stability.

Background: Intimate Partner Violence (IPV) is a serious health issue among couples which is recorded more among married partners. Dishearteningly, IPV among couples who are teachers is underreported due to shame, thereby increasing the prevalence of IPV in the area of the study. Objectives: The study examined physical and psychological health consequences of IPV on married primary school teachers. Methods: The design was a cross-sectional descriptive survey conducted on married primary school teachers in Delta South Senatorial zone of Delta State, Nigeria from 22nd February - 29th November, 2021. Three hundred and thirteen 313 (207 women and 106 men who have experienced various forms of IPV) who were identified as victims of IPV were used as participants in the study. Structured questionnaire was used to elicit information on physical and psychological health consequences of IPV on married teachers. Conclusion: The researchers concluded that there are severe and serious physical and psychological health consequences associated with IPV among married primary school teachers in Delta South Senatorial zone of Delta State, Nigeria. Urgent interventions such as public enlightenment, campaigns, workshops, seminars, community health talk-shows should be organized by government stakeholders, non-governmental organizations, community leaders on the prevention of IPV and its dare consequences for marital stability.

Maternal victimization and neglected offspring: Child marriage, IPV and depression symptoms among Salar Muslim women.

BACKGROUND: Child neglect is prevalent in western rural China, yet there is limited research among ethnic minority communities. The Salar, a Turkic-Muslim ethnic minority residing primarily in western China, also face this specific problem. The group is deeply influenced by ethnicity, Islam and Chinese Confucianism, which in turn makes women vulnerable to child marriage and IPV. These victimizations, coupled with various life stressors, further complicate the challenges of providing adequate care for their children. OBJECTIVE: This study hypothesizes a relationship between child neglect and maternal child marriage, IPV victimization, and depression symptoms. PARTICIPANTS AND SETTING: 201 married Salar women from five villages in Xunhua Salar Autonomous County, China, were randomly selected to participate in the study. METHOD: A probability proportional to size (PPS) sampling approach was used to collect a random representative multi-stage cluster sample in 2022. Random effects Poisson regression models were used to test the hypotheses. RESULTS: The participants reported a 65.6 % rate of child neglect and a 30.8 % rate of IPV in the past year. 37.6 % experienced child marriage. Results revealed significant associations between child neglect and child marriage, IPV, and depression symptoms. A two-way interaction between IPV and depression symptoms was strongly positively associated with child neglect. CONCLUSIONS: This research indicates that Salar Muslim mothers who have experienced child marriage, adulthood victimization, and depression are at a higher risk of neglecting their children. The findings represent a valuable initial step toward researching and addressing the protection needs of women and children from Muslim ethnic minorities in China.

Prevalence, Determinants, and Trends in the Experience and Perpetration of Intimate Partner Violence Among a Cohort of Gay, Bisexual, and Other Men Who Have Sex with Men in Montréal, Toronto, and Vancouver, Canada (2017-2022).

Purpose: Longitudinal data on the experience and perpetration of intimate partner violence (IPV) among gay, bisexual, and other men who have sex with men (GBM) are limited. We estimated the prevalence of past 6-month (P6M) physical and/or sexual IPV (hereafter IPV) experience and perpetration, identified their determinants, and assessed temporal trends, including the impact of the coronavirus disease (COVID)-19 pandemic. Methods: We used data from the Engage Cohort Study (2017-2022) of GBM recruited using respondent-driven sampling in Montréal, Toronto, and Vancouver. Adjusted prevalence ratios (aPRs) for determinants and self-reported P6M IPV were estimated using generalized estimating equations, accounting for attrition (inverse probability of censoring weights) and relevant covariates. Longitudinal trends of IPV were also assessed. Results: Between 2017 and 2022, 1455 partnered GBM (median age 32 years, 82% gay, and 71% White) had at least one follow-up visit. At baseline, 31% of participants experienced IPV in their lifetime and 17% reported ever perpetrating IPV. During follow-up, IPV experience was more common (6%, 95% confidence interval [CI]: 5%-7%) than perpetration (4%, 95% CI: 3%-5%). Factors associated with P6M IPV experience included prior IPV experience (aPR: 2.68, 95% CI: 1.76-4.08), lower education (aPR: 2.31, 95% CI: 1.32-4.04), and substance use (injection aPR: 5.05, 95% CI: 2.54-10.05, non-injection aPR: 1.68, 95% CI: 1.00-2.82). Similar factors were associated with IPV perpetration. IPV was stable over time; periods of COVID-19 restrictions were not associated with IPV changes in this cohort. Conclusion: Prevalence of IPV was high among GBM. Determinants related to marginalization were associated with an increased risk of IPV. Interventions should address these determinants to reduce IPV and improve health.

Risk for Experiencing Psychological and Sexual Abuse On- and Offline: A Comparison of Bisexual, Gay/Lesbian, and Heterosexual Women and Men.

Dating abuse research on lesbian, gay, and bisexual (LGB) populations tends to aggregate LGB participants for comparisons with heterosexuals and often excludes non-assaultive dating abuse and abuse that takes place on online dating applications. In the present study, we used the Pew Research Center's 2019 American Trends Panel Wave 56 dataset (N = 4712) to compare ever experiencing several types of non-assaultive on- and offline dating abuse between bisexual women (n = 402), lesbian women (n = 207), heterosexual women (n = 1802), bisexual men (n = 225), gay men (n = 575), and heterosexual men (n = 1501). We found that gay men and bisexual women generally had the greatest odds of experiencing online dating abuse. Bisexual and heterosexual women had the greatest odds of experiencing some offline abuse (e.g., being touched in an uncomfortable way), but gay men and bisexual women and men had the greatest odds of experiencing other offline abuse (e.g., having their contact information or a sexual image of them shared non-consensually). Findings highlight how assessments of non-assaultive dating abuse in on- and offline contexts via analyses of more specified gender/sex/ual identity groups can broaden understandings of dating abuse victimization, especially among sexual minority populations.

Coverage of the Combined DTaP-IPV/Hib Vaccine Among Children Aged 2-18 Months - 9 PLADs, China, 2019-2021.

What is already known on this topic?: In China, there is limited data available on the use and coverage of the non-program, combined diphtheria, tetanus toxoid, acellular pertussis adsorbed, inactivated poliovirus and haemophilus influenzae type b (DTaP-IPV/Hib) pentavalent vaccine, and its role as a substitute for the separately administered standalone program vaccines. What is added by this report?: We evaluated the use and coverage of the pentavalent vaccine in nine provincial-level administrative divisions (PLADs) spanning eastern, central, and western China from 2019 to 2021. Initial use and coverage were low, but demonstrated annual growth albeit with regional and urban-rural discrepancies. The pentavalent vaccine was increasingly substituted for standalone vaccines over the course of this period. What are the implications for public health practice?: Parents in China are increasingly opting to replace the standard program vaccines with voluntarily purchased combination vaccines, particularly the pentavalent vaccine. The development of combination vaccines should thus be promoted in China, as it could enhance utilization and coverage rates, and decrease the economic burden.

Antepartum Intimate Partner Violence: Development of a Risk Prediction Model.

Objectives: To explore socio-behavioral, clinical, and imaging findings associated with antepartum intimate partner violence (IPV) and aid in risk stratification of at-risk individuals. Methods: We analyzed electronic medical records during indexed pregnancies for 108 pregnant patients who self-reported antepartum IPV (cases) and 106 age-matched pregnant patients who did not self-report antepartum IPV (controls). Sociodemographic, clinical, and radiology data were analyzed via chi-squared and Fisher's exact tests with p < 0.05 as the threshold for significance. Stepwise logistic regression was applied to derive a risk prediction model. Results: The proportion of cases reporting emotional IPV (76% vs. 52%) and/or physical IPV (45% vs. 31%) during pregnancy significantly increased from prior to pregnancy. Cases were significantly more likely to report prepregnancy substance use (odds ratio [OR] = 2.60; 95% confidence interval [CI]: 1.13-5.98), sexually transmitted infections (OR = 3.48; 95%CI: 1.64-7.37), abortion (OR = 3.17; 95%CI: 1.79, 5.59), and preterm birth (OR = 5.97; 95%CI: 1.69-21.15). During pregnancy, cases were more likely to report unstable housing (OR = 5.26; 95%CI: 2.67-10.36), multigravidity (OR = 2.83; 95%CI: 1.44-5.58), multiparity (OR = 3.75; 95%CI: 1.72-8.20), anxiety (OR = 3.35; 95%CI: 1.85-6.08), depression (OR = 5.58; 95%CI: 3.07-10.16), substance use (OR = 2.92; 95%CI: 1.28-6.65), urinary tract infection (UTI) (OR = 3.26; 95%CI: 1.14-9.32), intrauterine growth restriction (OR = 10.71; 95%CI: 1.35-85.25), and cesarean delivery (OR = 2.25; 95%CI: 1.26-4.02). Cases had significantly more OBGYN abnormalities on imaging and canceled more radiological studies (OR = 5.31). Logistic regression found housing status, sexually transmitted infection history, preterm delivery history, abortion history, depression, and antepartum UTI predictive of antepartum IPV. The risk prediction model achieved good calibration with an area under the curve of 0.79. Conclusions: This study identifies significant disparities among patients experiencing antepartum IPV, and our proposed risk prediction model can inform risk assessment in this setting.

Predicting Recovery Pathways in Jewish Ultra-Orthodox Intimate Partner Violence Survivors: A Structural Equation Modeling Approach.

Cultural and religious norms, as well as trauma-related cognitions and recovery actions, are known to impact the well-being of survivors of intimate partner violence (IPV). Although acknowledged as a key component, there is scant research on the recovery trajectories of women who have experienced IPV, in particular on survivors from collectivistic societies such as the Jewish Ultra-Orthodox (JUO) community in Israel. A mediation model examined the recovery process of 261 Israeli JUO survivors. In particular, it tested whether the normalization of violence and women's endorsement of Jewish religious norms that justify violence would be directly and negatively associated with women's well-being and positively associated with psychopathology. Additionally, it examined whether women's normalization of violence and support of religious norms would positively predict women's negative trauma-related cognitions. In turn, these cognitions were expected to negatively predict women's engagement in recovery actions, help-seeking behaviors, and faith-based responses but positively predict disengagement responses. The model further posited that women's engagement in steps toward recovery, help-seeking behaviors, and faith-based responses would positively predict women's well-being and negatively predict psychopathology. In contrast, women's disengagement responses would negatively predict women's well-being and positively predict their psychopathology. Bootstrap results indicated that supporting religious norms positively predicted women's trauma-related cognitions, which then negatively predicted women's recovery actions, help-seeking behaviors, and faith-based responses but positively predicted women's disengagement responses. Women's recovery actions and faith-based responses positively predicted women's well-being, while disengagement responses positively predicted women's psychopathology. Contrary to expectations, help-seeking behaviors positively predicted psychopathology.

Immunogenicity evaluation of primary polio vaccination schedule with inactivated poliovirus vaccines and bivalent oral poliovirus vaccine.

BACKGROUND: To assess the immunogenicity of the current primary polio vaccination schedule in China and compare it with alternative schedules using Sabin or Salk-strain IPV (sIPV, wIPV). METHODS: A cross-sectional investigation was conducted at four sites in Chongqing, China, healthy infants aged 60-89 days were conveniently recruited and divided into four groups according to their received primary polio vaccination schedules (2sIPV + bOPV, 2wIPV + bOPV, 3sIPV, and 3wIPV). The sero-protection and neutralizing antibody titers against poliovirus serotypes (type 1, 2, and 3) were compared after the last dose. RESULTS: There were 408 infants completed the protocol. The observed seropositivity was more than 96% against poliovirus types 1, 2, and 3 in all groups. IPV-only groups induced higher antibody titers(GMT) against poliovirus type 2 (Median:192, QR: 96-384, P<0.05) than the "2IPV + bOPV" group. While the "2IPV + bOPV" group induced significantly higher antibody titers against poliovirus type 1 (Median:2048, QR: 768-2048, P<0.05)and type 3 (Median:2048, QR: 512-2048, P<0.05) than the IPV-only group. CONCLUSIONS: Our findings have proved that the two doses of IPV with one dose of bOPV is currently the best polio routine immunization schedule in China.

Immunogenicity and safety of adsorbed diphtheria-purified pertussis-tetanus-inactivated polio (Sabin strain)-Haemophilus type b conjugate combined vaccine (DPT-IPV-Hib) in healthy Japanese Infants ≥ 2 and < 43 months of Age: A phase III, multicenter, active controlled, assessor-blinded, randomized, parallel-group study.

OBJECTIVE: This study investigated the immunogenicity and safety of a pentavalent vaccine Gobik (DPT-IPV-Haemophilus influenzae type b [Hib]) in healthy Japanese infants aged ≥ 2 and < 43 months using a concomitant vaccination with ActHIB® (Hib) and Tetrabik (DPT-IPV) as a comparator. METHODS: This study was conducted as a phase 3, multicenter, active controlled, assessor-blinded, randomized, parallel-group study. Participants received a total of 4 subcutaneous doses (3 primary immunization doses and a booster dose) of either the experimental drug (DPT-IPV-Hib) or the active comparator (Hib + DPT-IPV). The primary endpoints were the anti-PRP antibody prevalence rate with ≥ 1 µg/mL, and the antibody prevalence rates against pertussis, diphtheria toxin, tetanus toxin, and attenuated poliovirus after the primary immunization. RESULTS: In 267 randomized participants (133 in the DPT-IPV-Hib group and 134 in the Hib + DPT-IPV group), the antibody prevalence rates after the primary immunization in both groups were 100.0 % and 88.7 % for anti-PRP antibody with ≥ 1 µg/mL, 99.2 % and 98.5 % against diphtheria toxin, and 100.0 % and 99.2 % against tetanus toxin, respectively. The antibody prevalence rates against pertussis and attenuated poliovirus were 100.0 % in both groups. The non-inferiority of the DPT-IPV-Hib group to the Hib + DPT-IPV group was verified for all measured antibodies. In both groups, all the GMTs of antibodies after the primary immunization were higher than those before the first dose, and those after the booster dose were higher than those after the primary immunization. No safety issues were identified. CONCLUSION: A single-agent Gobik, the first DPT-IPV-Hib pentavalent vaccine approved in Japan, was confirmed to simultaneously provide primary and booster immunizations against Hib infection, pertussis, diphtheria, tetanus, and poliomyelitis and to have a preventive effect and safety comparable to concomitant vaccination with Hib (ActHIB®) and DPT-IPV quadrivalent vaccine (Tetrabik).

Exposure to maternal experiences of IPV in early childhood and sleep health in adolescence.

BACKGROUND: Half of US women will experience intimate partner violence (IPV), and nearly all children in families experiencing such violence will be exposed. The negative effects of IPV exposure on children's mental and physical health are well-documented; however, less is known about effects on children's sleep health, a key marker of well-being. OBJECTIVE: This study examines the associations of early childhood exposure to maternal experiences of IPV with sleep health in adolescence, focusing on multiple dimensions of sleep health and differences by child sex. PARTICIPANTS AND SETTING: We rely on data from the Future of Families and Child Wellbeing Study, a population-based study following 5000 children in large US cities, from birth to age 15. Analyses are based on 2687 adolescents interviewed at the year-15 follow-up. METHODS: Early childhood exposure to IPV is based on mothers' reports of her experiences of IPV from the child's birth to age 5. Adolescent sleep health is measured using 6 items approximating the BEARS sleep problem scale, at age 15. We estimate multivariate linear regression models to examine associations of early childhood IPV exposure with adolescent sleep health and stratify models by child sex. RESULTS: Early childhood IPV exposure is associated with worse overall sleep health (ß = 0.08; p < 0.001) and multiple dimensions of poor sleep health in adolescence. Associations are notably stronger among girls than boys. CONCLUSIONS: The strong and lasting associations of early childhood exposure to IPV with adolescents' sleep health, particularly among girls, has important consequences for addressing adolescent health disparities.

Surveillance for adverse events following immunization with DTaP-containing combination vaccines in Linping, China, 2019-2022.

Background: The DTaP-Hib and DTaP-IPV/Hib combination vaccine can be used as a substitute for the diphtheria, tetanus, and acellular pertussis combined vaccine (DTaP). We aimed to evaluate the safety of multi-component vaccines containing DTaP by analyzing the reporting rates and characteristics of adverse events following immunization (AEFIs) in Linping District during the years 2019 to 2022. Methods: We obtained data of AEFI and vaccination from the National AEFI Surveillance System of China and Zhejiang Municipal Immunization Information Management System, respectively, during 2019-2022 for a descriptive, epidemiological analysis. Results: The total number of AEFI reported following vaccinations with DTaP-containing combination vaccines was 802 in Linping District from 2019 to 2022. The overall reporting rates of AEFIs following DTaP, DTaP-Hib, and DTaP-IPV/Hib vaccinations were 445.72 (537 cases), 536.29 (45 cases), and 306.13 (220 cases) per 100,000 doses in Linping District from 2019 to 2022, respectively. Only one case of a serious AEFI following DTaP vaccination, with a reporting rate of 0.83 per 100,000 doses. The composition ratio of vaccine product-related reactions for DTaP, DTaP-Hib, and DTaP-IPV/Hib were 99.81, 97.78, and 100.00%, respectively. The composition ratio of coincidental events for DTaP and DTaP-Hib were 0.19 and 2.22%, respectively. The reporting rates of total AEFIs for DTaP-IPV/Hib were lower than for DTaP. The reporting rate of local induration for DTaP-Hib was lower than for DTaP, and the reporting rates of local redness & swelling and local induration for DTaP-IPV/Hib were both lower than for DTaP. DTaP-IPV/Hib had a higher proportion of AEFIs in first quarter compared to DTaP. The reporting rate after the second dose of DTaP-Hib was higher than that of DTaP, and the reporting rates of AEFIs after the first dose and third dose of DTaP-IPV/Hib were lower than DTaP. Conclusion: The reported AEFIs to multi-component vaccines containing DTaP components during 2019-2022 in Linping District were mainly mild vaccine reactions. DTaP-containing combination vaccines demonstrated a good safety profile.

ACTOR: Adaptive Control of Transmission Power in RPL.

RPL-Routing Protocol for Low-Power and Lossy Networks (usually pronounced "ripple")-is the de facto standard for IoT networks. However, it neglects to exploit IoT devices' full capacity to optimize their transmission power, mainly because it is quite challenging to do so in parallel with the routing strategy, given the dynamic nature of wireless links and the typically constrained resources of IoT devices. Adapting the transmission power requires dynamically assessing many parameters, such as the probability of packet collisions, energy consumption, the number of hops, and interference. This paper introduces Adaptive Control of Transmission Power for RPL (ACTOR) for the dynamic optimization of transmission power. ACTOR aims to improve throughput in dense networks by passively exploring different transmission power levels. The classic solutions of bandit theory, including the Upper Confidence Bound (UCB) and Discounted UCB, accelerate the convergence of the exploration and guarantee its optimality. ACTOR is also enhanced via mechanisms to blacklist undesirable transmission power levels and stabilize the topology of parent-child negotiations. The results of the experiments conducted on our 40-node, 12-node testbed demonstrate that ACTOR achieves a higher packet delivery ratio by almost 20%, reduces the transmission power of nodes by up to 10 dBm, and maintains a stable topology with significantly fewer parent switches compared to the standard RPL and the selected benchmarks. These findings are consistent with simulations conducted across 7 different scenarios, where improvements in end-to-end delay, packet delivery, and energy consumption were observed by up to 50%.

Racial Microaggressions Mediate the Association Between Posttraumatic Stress and Alcohol Use Among Women of Color Experiencing Intimate Partner Violence.

Objective: Women of Color (WoC) experiencing intimate partner violence (IPV) have elevated rates of posttraumatic stress disorder (PTSD) and alcohol use and related harm (e.g., increased alcohol use and negative consequences). This secondary data analysis assessed the role of racial microaggressions in the association between PTSD and alcohol use and related harm among WoC experiencing IPV. Methods: Participants were 103 WoC currently experiencing IPV and using substances (Mage=40.39, 51.5% Black) who were recruited from the community and completed assessments of PTSD, racial microaggressions, and alcohol use and related harm. Results: Assumptions of Inferiority (e.g., intelligence; B = 1.44, SE = 0.90, 95% CI [0.10, 3.54]) and Environmental Microaggressions (e.g., portrayal in media; B = 1.88, SE = 1.03, 95% CI [0.28, 4.30]) explained the association between PTSD and alcohol use and related harm. Conclusions: Findings underscore the influence of specific microaggressions in the relation between PTSD and alcohol use and related harm among WoC experiencing IPV.

Changes in vaccination practices among infants after the introduction of DTaP-IPV/Hib combination vaccines.

Background: Diphtheria-tetanus-acellular pertussis, polio, and Haemophilus influenza type B (DTaP-IPV/Hib) combination vaccine was introduced as a part of the Korea National Immunization Program (NIP) on June 19, 2017. Combination vaccines can improve vaccination rates by simplifying the vaccination schedule. Objective: To explain how the introduction of DTaP-IPV/Hib in the NIP has changed vaccination practices for infants. Methods: Using a nationwide vaccine registry, the proportion of infants who completed the full recommended doses of the primary series of DTaP, IPV, and Hib (D-I-H) within 12 months of age was estimated among those born between 2013 and 2019. Among those, the proportions of those who received the same DTaP components for all 3 doses during the primary series were calculated for the 2013-2016 and the 2017-2019 birth cohorts. Those who received the same component of DTaP throughout the entire primary vaccination schedule were categorized into 3 groups by DTaP components to compare the average frequency of medical visits for vaccination. Results: A total of 2,703,822 infants were born between 2013 and 2019, of which 96.7% completed full doses of the primary D-I-H series within 12 months of age. For the 2013-2016 birth cohorts, most received DTaP-IPV-only (75.4%), while most of the 2017-2019 birth cohorts received DTaP-IPV/Hib-only (81.0%) to complete the 3 doses for primary D-I-H series. The average frequency of medical visits for vaccination showed a significant difference across the 3 groups classified by DTaP components in every birth cohort (p < 0.001). Conclusions: After the introduction of DTaP-IPV/Hib, most infants completed the primary D-I-H series with the combination vaccine and there was a significant reduction in the average number of medical visits for vaccination. Our findings provide important insights for countries considering the introduction of combination vaccines into their NIP.

3MSF: A Multi-Modal Adaptation of the 6TiSCH Minimal Scheduling Function for the Industrial IoT.

Although wireless devices continuously gain communication capabilities, even state-of-the-art Industrial Internet of Things (IIoT) architectures, such as Internet Protocol version 6 over the Time-Slotted Channel Hopping (TSCH) mode of IEEE 802.15.4 (6TiSCH), continue to use network-wide, fixed link configurations. This presents a missed opportunity to (1) forego the need for rigorous manual setup of new deployments; and (2) provide full coverage of particularly heterogeneous and/or dynamic industrial sites. As such, we devised the Multi-Modal Minimal Scheduling Function (3MSF) for the TSCH link layer, which, combined with previous work on the routing layer, results in a 6TiSCH architecture able to dynamically exploit modern multi-modal hardware on a per-link basis through variable-duration timeslots, simultaneous transmission, and routing metric normalization. This paper describes, in great detail, its design and discusses the rationale behind every choice made. Finally, we evaluate three basic scenarios through simulations, showcasing both the functionality and flexibility of our 6TiSCH implementation.

Clinical application of intrapulmonary percussive ventilation: A scoping review.

Impaired respiratory function secondary to acute or chronic respiratory disease poses a significant clinical and healthcare burden. Intrapulmonary percussive ventilation (IPV) is used in various clinical settings to treat excessive airway secretions, pulmonary atelectasis, and impaired gas exchange. Despite IPV's wide use, there is a lack of clinical guidance on IPV application which may lead to inconsistency in clinical practice. This scoping review aimed to summarise the clinical application methods and dosage of IPV used by clinicians and researchers to provide guidance. A two-staged systematic search was conducted to retrieve studies that used IPV in inpatient and outpatient settings. MEDLINE, EMBASE, CINAHL, Scopus, and Google scholar were searched from January 1979 till 2022. Studies with patients aged ≥16 years and published in any language were included. Two reviewers independently screened the title and abstract, reviewed full text articles, and extracted data. Search yielded 514 studies. After removing duplicates and irrelevant studies, 25 studies with 905 participants met the inclusion criteria. This is the first scoping review to summarise IPV application methods and dosages from the available studies in intensive care unit (ICU), acute inpatient (non-ICU), and outpatient settings. Some variations in clinical applications and prescribed dosages of IPV were noted. Despite variations, common trends in clinical application and prescription of IPV dosages were observed and summarised to assist clinicians with IPV intervention. Although an evidence-based clinical guideline could not be provided, this review provides detailed information on IPV application and dosages in order to provide clinical guidance and lays a foundation towards developing a clinical practice guideline in the future.

Pathways to Resistance: Theorizing Trauma and Women's Use of Force in Intimate Relationships.

Using a feminist pathways general strain perspective, we explore the victim-offender continuum for women who perpetrated intimate partner violence/abuse (IPV/A). We use data from 86 women court-mandated to "female offender" domestic violence treatment programs, located in an American East Coast state, who were surveyed about their adverse childhood experiences and mental health/well-being as adults. Findings from bivariate linear regressions indicate childhood trauma negatively affects adult mental health/well-being, exacerbated for Black Indigenous People of Color women, suggesting a victim rather than an offender categorization for women using force against their abusive partner. Results imply the need to consider women's traumatic histories and IPV/A victimization, given an incident-driven system that criminalizes victimization over the life course.
