The anthocyanin extracts (AE) from different sources were commonly used in preparing an indicator film to reflect food freshness, as AE contained rich anthocyanins which acted as the pH-sensitive ingredient. Therefore, this study aimed to compare the impact of AE sources (including rosella extract (RE), Lycium ruthenicum Murray (LE), and mulberry extracts (ME)) on the film properties and pH-sensitivity of konjac glucomannan/zein (KZ) composite film. Results showed that the three AEs had significantly different anthocyanin species and total contents, contributing to their different color changes in response to the pH changes. Some film property changes were not affected by the different AE, but mostly, different film property changing extents were observed, such as thickness, color, mechanical properties, hydrophilicity, antioxidant property, and water vapor permeability. This indicated that the hydrophilic plasticizing and void-filling effects of the anthocyanin were impacted by the anthocyanin structure. On the other hand, the impact of AE sources on the pH sensitivity and volatile ammonia sensitivity of the films was significantly different, mainly relating to both anthocyanin contents and composition. Finally, the KZ film with LE addition of 10% was suggested to be applied in the intelligent food packaging, as the addition of anthocyanin was relatively low and the film had both good pH sensitivity and film properties.

The article discusses the preservation of vaccine-associated antibodies against vaccine-preventable infections (VPIs) in patients undergoing chimeric antigen receptor T-cell (CAR-T) therapy for lymphoma. The study evaluated seropositivity against VPIs between 0 and 6 months post-infusion and found that a high proportion of patients maintained antibodies against viral VPIs and tetanus. The results suggest the need for individualized vaccine schedules post-CAR-T to ensure optimal immune response. The study had strengths in complete longitudinal follow-up but was limited by a small sample size. Further research is needed to determine the best approach for preventing infections in CAR-T patients. [Extracted from the article]

Background: The rubella virus is a major contributor to birth defects globally and is preventable by vaccination. In 2020, the world was supposed to be free of both rubella and Congenital Rubella Syndrome (CRS) however this goal has yet to be realized with only 93 out of 194 WHO member states confirmed rubella-free in 2020. Methods: A retrospective measles and rubella case-based surveillance data record review was conducted from 2018 to 2022 to document rubella epidemiology after the introduction of rubella vaccination in Lesotho and progress toward elimination. All samples submitted for surveillance purposes and tested for rubella were considered but only filtered according to inclusion and exclusion criteria. Descriptive statistics were used to analyse the data. Results: Of the 1041 samples that were tested for rubella between 2018 and 2022, 10 (1%) were confirmed measles positive and were excluded from further analysis. The median age of the respondents was 6.0 (IQR 4.0–8.0.) years. About 643 (62.4%) of respondents were in the age category of 5 - <13 years. Rubella prevalence was 1% (95% CI; 0.5 -1.8%). The non-measles, non-rubella rash illness rate of 2 per 100 000 population was obtained at the national level each year of the study period but by only 2 of the country's 10 districts in 2021. Conclusions: The study showed low rubella prevalence. Rubella infection was predominant in those aged 5 - < 13 years. Failure to meet surveillance targets at certain time points during the study period may have led to an underestimation of rubella cases. There is a need to improve the quality of measles and rubella surveillance in Lesotho. Supplementary immunization activities would also be useful in closing immunity gaps, limiting outbreaks, and advancing rubella and CRS elimination in Lesotho. [ABSTRACT FROM AUTHOR]

Duplicated genes are thought to follow one of three evolutionary trajectories that resolve their redundancy: neofunctionalization, subfunctionalization, or pseudogenization. Differences in expression patterns have been documented for many duplicated gene pairs and interpreted as evidence of subfunctionalization and a loss of redundancy. However, little is known about the functional impact of such differences and about their molecular basis. Here, we investigate the genetic and molecular basis for the partial loss of redundancy between the two BLADE-ON-PETIOLE genes BOP1 and BOP2 in red shepherd's purse (Capsella rubella) compared to Arabidopsis (Arabidopsis thaliana). While both genes remain almost fully redundant in A. thaliana, BOP1 in C. rubella can no longer ensure wild-type floral organ numbers and suppress bract formation, due to an altered expression pattern in the region of the cryptic bract primordium. We use two complementary approaches, transgenic rescue of A. thaliana atbop1 atbop2 double mutants and deletions in the endogenous AtBOP1 promoter, to demonstrate that several BOP1 promoter regions containing conserved noncoding sequences interact in a nonadditive manner to control BOP1 expression in the bract primordium and that changes in these interactions underlie the evolutionary divergence between C. rubella and A. thaliana BOP1 expression and activity. Similarly, altered interactions between cis-regulatory regions underlie the divergence in functional promoter architecture related to the control of floral organ abscission by BOP1. These findings highlight the complexity of promoter architecture in plants and suggest that changes in the interactions between cis-regulatory elements are key drivers for evolutionary divergence in gene expression and the loss of redundancy. Evolutionary changes affecting the interactions between cis-regulatory elements in the promoter of duplicated development genes partially resolve their redundancy in Capsella rubella.

Congenital Rubella, AIDS, and other human diseases may pass from mother to fetus through the placenta. On the other side, insects and plants often transmit vertically by their eggs/seeds. Here, we study an SEIR epidemic model with vertical transmission in a multi‐patch context to explore the spread of disease in a population divided into n$$ n $$ distinct regions. The local and global stability of disease‐free equilibrium for the n‐patch model system has been determined in terms of the basic reproduction number (R0)$$ \left({R}_0\right) $$. Moreover, we discuss the existence and stability of endemic equilibrium for different cases in two symmetric regions. Our findings indicate that when R0$$ {R}_0 $$ is less than one, the disease‐free equilibrium is globally asymptotically stable, whereas when R0$$ {R}_0 $$ is greater than one, it is unstable. As a result, for R0>1$$ {R}_0>1 $$, the model system has an unique endemic equilibrium that is always locally asymptotically stable. The dynamics of the proposed model system depending on the distribution of infected individuals across various regions have been studied. The findings suggest that the movements from high disease risk regions to low disease risks may increase the number of the infected population in the community. The value of R0$$ {R}_0 $$ could be enhanced by increasing the values of any vertical transmission parameter. However, the changes in the values of R0$$ {R}_0 $$ are relatively minor. Our findings also imply that while migrations of all individuals across symmetric regions do not leave any impact on the equilibrium state of the infected population, they do affect the trajectory of the solution to reach a steady‐state. The flow of people between the two symmetrical regions could not alter the endemicity. [ABSTRACT FROM AUTHOR]

Immunity alterations have been observed in bipolar disorder (BD). However, whether serum positivity of antibodies to Toxoplasma gondii (T gondii) , rubella, and cytomegalovirus (CMV) shared clinical relevance with BD, remains controversial. This study aimed to investigate this association. Antibody seropositivity of IgM and IgG to T gondii , rubella virus, and CMV of females with BD and controls was extracted based on medical records from January 2018 to January 2023. Family history, type of BD, onset age, and psychotic symptom history were also collected. 585 individuals with BD and 800 healthy controls were involved. Individuals with BD revealed a lower positive rate of T gondii IgG in the 10–20 aged group (OR = 0.10), and a higher positive rate of rubella IgG in the 10–20 (OR = 5.44) and 20–30 aged group (OR = 3.15). BD with family history preferred a higher positive rate of T gondii IgG (OR = 24.00). Type-I BD owned a decreased positive rate of rubella IgG (OR = 0.37) and an elevated positive rate of CMV IgG (OR = 2.12) compared to type-II BD, while BD with early onset showed contrast results compared to BD without early onset (Rubella IgG, OR = 2.54; CMV IgG, OR = 0.26). BD with psychotic symptom history displayed a lower positive rate of rubella IgG (OR = 0.50). Absence of male evidence and control of socioeconomic status and environmental exposure. Differential antibody seropositive rates of T gondii , rubella, and cytomegalovirus in BD were observed. • Serum pathogen antibody positive rates varied across age groups. • T gondii IgG was associated with family history of BD. • Rubella IgG was associated with type-II BD, BD with early onset and BD without psychotic symptom history. • CMV IgG was associated with type-I BD and BD without early onset.

This article discusses a case of a 13-year-old boy who developed Febrile Infection-Related Epilepsy Syndrome (FIRES) after contracting COVID-19. FIRES is a subtype of New-Onset Refractory Status Epilepticus (NORSE) characterized by new-onset status epilepticus without a clear cause. The boy was treated with Anakinra, a medication used for rheumatologic conditions, and showed a rapid response with seizure control. The article highlights the potential use of Anakinra in COVID-19-associated FIRES and the importance of early treatment. It also mentions the presence of the "claustrum sign" on imaging, which is a biomarker for FIRES. [Extracted from the article]

Introduction During the coronavirus disease of 2019 (COVID-19) pandemic, routine childhood immunization rates dropped dramatically across the world, and the Military Health System (MHS) was no exception. In the MHS, which is a large, universally covered, low-to-no-cost health system, the immunization rates with the measles, mumps, and rubella (MMR) vaccine remain below the rate necessary to prevent community transmission of measles. We aimed to improve childhood immunization rates in the MHS with an expansive quality improvement project. Materials and Methods Measles, mumps, and rubella immunization rates served as proxy outcome measures for routine immunization rates tracked by the Center for Disease Control multi-immunization combination measures. The tracked measure was the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2, respectively. Various countermeasures were implemented throughout the study period, and standard quality improvement analyses informed the effect of countermeasures. Results By January 2023, the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2 was 85% and 91%, respectively, with no positive shift in immunization rates despite various countermeasures introduced during the study period. For reference, the MMR immunization rates of commercial health maintenance organization and commercial preferred provider organization for 24-month-old populations were 92% and 90.3%, respectively. On chart review, the most common cause for under-immunization (55%) was vaccine abandonment. MMR #1 rates rose to 92% in 24-month olds. Conclusions Measles, mumps, and rubella immunization rates within the MHS remained below commercial health system rates and below public health standards required for herd immunity despite various countermeasures throughout the COVID-19 pandemic. Immunization rates increased with age, suggesting that children within the MHS eventually catch up despite potential barriers. [ABSTRACT FROM AUTHOR]

Testing for immunity to measles, mumps, and rubella should include only immunoglobulin G (IgG); immunoglobulin M (IgM) testing is appropriate only if acute illness is suspected. The appropriateness of measles, mumps, and rubella IgM testing was evaluated in a national administrative dataset. Laboratory testing for measles, mumps, and rubella during 2019–2022 was analyzed in 2024 using HealthVerity administrative claims and laboratory data. IgG, IgM, and reverse-transcriptase polymerase chain reaction (RT-PCR) testing are described by year, demographics, and region. IgM testing was examined for appropriateness, defined as an IgM test combined with diagnostic codes indicative of acute illness. During 2019–2022, IgM testing represented a small proportion of serologic testing (measles: 3.3%, mumps: 2.4%, rubella: 2.1%) but appeared to be appropriately performed in only 15.4% of cases for measles, 32.8% of cases for mumps, and 10.2% of cases for rubella. IgM testing was more commonly performed for female patients, with the largest discrepancy seen for rubella (90.5% female vs 9.5% male). IgM for measles and mumps was more often performed appropriately for persons aged 0–19 years (37.6% and 60.1%) compared with persons aged 20–49 years (11.8% and 22.0%) and 50+ years (16.5% and 33.8%). The majority of IgM testing for measles, mumps, and rubella during this period appeared inappropriate. Clinicians and health systems could ensure that IgG testing alone is performed when evaluating for immunity through modifications to electronic medical records and commercial laboratories could ensure that providers are able to test for IgG alone when evaluating immunity.

We report a 12‐month‐old boy with a skin eruption that developed 15 days after receiving the measles, mumps, rubella (MMR), pneumococcal, and meningococcal vaccines, consistent with the diagnosis of Wells syndrome. Patch testing showed a positive reaction to gelatin, which is used as a stabilizer for both live and inactivated vaccines. Gelatin was only present in the MMR vaccine. [ABSTRACT FROM AUTHOR]

Introduction: Congenital rubella syndrome (CRS) is associated with severe birth defects, that lead to disability in later life. Hence, early detection and intervention are needed to prevent permanent disability and mortality in children with CRS. We evaluated the time to diagnosis or correction intervention related to survival rate using survival analysis. Methodology: A retrospective cohort study was conducted to evaluate the follow-up of CRS-confirmed cases from 2011–2018 at a national referral hospital in Jakarta, Indonesia. Parents of eligible children who registered in the national CRS registry as laboratory-confirmed CRS cases were contacted through phone calls or home visits and interviewed about the current situation of their child’s health. We also obtained clinical data from the medical records. Results: Fifty children, age 4 to 14 years, identified with laboratory-confirmed CRS were included in this study. Half (54%) of these children were female. All were born from mothers with no previous rubella vaccination history. Ophthalmic abnormalities such as congenital cataracts (88%) were the most common birth defect. Multiple congenital abnormalities including congenital heart disease, ocular abnormalities, and auditory defects were identified in 52% of the children. Based on Kaplan-Meier analysis, 50% of children were diagnosed at four months. Ophthalmic corrections such as cataract surgery were performed earlier than heart or auditory correction, with 50% of children undergoing eye correction one month after the diagnosis. Conclusions: There is a vital need to implement CRS surveillance in Indonesia to know the burden of CRS and reinforce the preventive actions, including vaccination against rubella.

Background Ensuring vaccination coverage reaches established herd immunity thresholds (HITs) is the cornerstone of any vaccination programme. Diverse migrant populations in European countries have been associated with cases of vaccine-preventable diseases (VPDs) and outbreaks, yet it is not clear to what extent they are an under-immunized group. Methods We did a systematic review and meta-analysis to synthesize peer-reviewed published primary research reporting data on the immune status of migrants in EU/EEA countries, the UK and Switzerland, calculating their pooled immunity coverage for measles, mumps, rubella and diphtheria using random-effects models. We searched on Web of Science, Embase, Global Health and MEDLINE (1 January 2000 to 10 June 2022), with no language restrictions. The protocol is registered with PROSPERO (CRD42018103666). Findings Of 1103 abstracts screened, 62 met eligibility criteria, of which 39 were included in the meta-analysis. The meta-analysis included 75 089 migrants, predominantly from outside Europe. Pooled immunity coverage among migrant populations was well below the recommended HIT for diphtheria (n  = 7, 57.4% [95% confidence interval (CI): 43.1–71.7%] I 2 = 99% vs HIT 83–86%), measles (n  = 21, 83.7% [95% CI: 79.2–88.2] I 2 = 99% vs HIT 93–95%) and mumps (n  = 8, 67.1% [95% CI: 50.6–83.6] I 2 = 99% vs HIT 88–93%) and midway for rubella (n  = 29, 85.6% [95% CI: 83.1–88.1%] I 2 = 99% vs HIT 83–94%), with high heterogeneity across studies. Interpretation Migrants in Europe are an under-immunized group for a range of important VPDs, with this study reinforcing the importance of engaging children, adolescents and adults in 'catch-up' vaccination initiatives on arrival for vaccines, doses and boosters they may have missed in their home countries. Co-designing strategies to strengthen catch-up vaccination across the life course in under-immunized groups is an important next step if we are to meet European and global targets for VPD elimination and control and ensure vaccine equity.

Vaccination rates for mumps, measles, and rubella (MMR) and tetanus, diphtheria, pertussis, and polio (Tdap‐IPV) fall short of global targets, highlighting the need for vaccination interventions. This study examines the effectiveness of a city‐wide school‐based educational vaccination intervention as part of an on‐site vaccination program aimed at increasing MMR and Tdap‐IPV vaccination rates versus on‐site vaccination alone among sociodemographically diverse students from Berlin, Germany. The study was a 1:1 two‐arm cluster randomized controlled trial, with schools randomly assigned to either the Educational Class Condition (ECC) or the Low‐Intensity Information Condition (LIIC). Both received an on‐site vaccination program, while students in the ECC received an additional educational unit. Primary outcomes were MMR and Tdap‐IPV vaccination rates. In total, 6512 students from 25 randomly selected urban area secondary schools participated. For students providing their vaccination documents on the day of the intervention (2273, 34.9%), adjusted Poisson mixed models revealed significant between‐group differences in favor of the ECC (MMR: logRR = 0.47, 95%CI [0.01,0.92], RR = 1.59; Tdap‐IPV: logRR = 0.28, 95%CI [0.10,0.47], RR = 1.32). When adjusting for socioeconomic and migration background, between‐group differences became non‐significant for MMR but remained significant for Tdap‐IPV. Findings suggest that educational, school‐based on‐site vaccination appears to be a promising strategy for increasing vaccination uptake in adolescents. [ABSTRACT FROM AUTHOR]

Rubella is a highly contagious viral disease that can be transmitted through contact with infected people or objects. If a pregnant woman is infected with rubella, the virus can be transmitted to the fetus, which can cause birth defects. To prevent rubella, children need to receive the MMR vaccine twice. In this study, we developed a deterministic and stochastic mathematical model to investigate the dynamics of rubella infection, considering vertical transmission and environmental factors. The model divides the population into five groups: susceptible, first vaccinated, protected, infected, and recovered. From the perspective of the qualitative behavior of the model, the model is bound to an invariant domain, and all solutions within the compartment are positive. We analyzed the equilibrium point of the model and its stability, and we determined the basic reproductive number using the next‐generation matrix. The basic reproductive number for the stochastic model is smaller than that for the deterministic model due to randomness. By comparing the two models in terms of the basic reproductive number, extending the deterministic model to a stochastic model can provide more realistic information about the disease, predict its dynamic propagation, and give suggestions for control mechanisms. Numerical simulations and sensitivity analyses were performed to study the influence of fundamental parameters, and the simulation results were displayed graphically using the MATLAB computer software. Parameter values were obtained from published papers, some of which were assumed. The simulation results show that the stochastic curve is not as smooth as the deterministic curve due to the randomness of the rubella. The consideration of the double vaccination dose and white noise intensity plays an important role in predicting disease status and minimizing and eradicating rubella. Therefore, reducing vertical infection and transmission rates and increasing vaccination and recovery rates will help to prevent and control the spread of rubella. [ABSTRACT FROM AUTHOR]

Background and purpose: The seroprevalence of antibodies against measles, mumps, and rubella (MMR) was evaluated 17 years following a mass vaccination campaign in individuals aged 2 to 22 years who had received routine immunization but were not eligible for an extended immunization program. Methods: Samples were acquired from Iran's National Measles Laboratory (NML), with individuals showing positive IgM results excluded. Out of the samples collected in 2020, a random selection of 290 serum samples was chosen, representing individuals between the ages of 2 and 22 years from diverse regions in the country. These samples were subjected to analysis using an enzyme-linked immunosorbent assay (ELISA) to quantify specific IgG antibodies against MMR. Results: The seroprevalence rates of antibodies for measles, mumps, and rubella were determined to be 76.2%, 89.3%, and 76.9%, respectively. Younger age groups exhibited higher seropositivity rates for measles and mumps, whereas the 7- to 11-year-old group demonstrated the highest seropositivity rate for rubella. A reduction in antibody status was observed from younger to older age groups, particularly those aged 17–22. Conclusion: The study unveiled suboptimal antibody levels for measles and rubella, highlighting the necessity for further investigation and potential adjustments to future vaccination strategies. Moreover, the decline in antibody status post-vaccination can accumulate in seronegative individuals over time, elevating the risk of outbreaks. [ABSTRACT FROM AUTHOR]

Objective. To estimate the proportion of vaccinated subjects and associated factors in adults and older adults in Mexico. Materials and methods. Analysis of data obtained from the Ensanut Continua 2021-2023 and comparison with the proportion of vaccinated subjects in Ensanut 2012. Results. Given that only 6.8% of adults and older adults in Ensanut Continua 2021-2023 and 17.7% in Ensanut 2012 could accredit their vaccination status, the analysis is based on self-report. When comparing Ensanut Continua 2021-2023 with Ensanut 2012, the proportion of vaccinated subjects according to age group and biologic was as follows: adults aged 20-59 years, tetanus: 66.87 vs. 78.08%; women of childbearing age, tetanus: 71.1 vs. 82.0%; measles/rubella: 36.8 vs. 48.5%; older adults, tetanus: 59.5 vs. 65.86%; influenza: 58.7 vs. 51.9%; pneumococcus: 34.8 vs. 45.9%. Covid-19 vaccine coverage in younger and older adults was 86.6 and 89.2%, respectively. Incomplete schedules were more prevalent in men and in people without health insurance, among adults aged 20 to 59; and in people without health insurance, among adults aged 60 years or older. Discussion. A considerable proportion of adults and older adults are not protected against vaccinepreventable diseases in 2021-2023. [ABSTRACT FROM AUTHOR]

Background: Ovarian cancer has the highest mortality among gynecologic cancers, primarily because it typically is diagnosed at a late stage and because of the development of chemoresistance in recurrent disease. Improving outcomes in women with platinumresistant ovarian cancer is a substantial unmet need. Activation of the glucocorticoid receptor (GR) by cortisol has been shown to suppress the apoptotic pathways used by cytotoxic agents, limiting their efficacy. Selective GR modulation may be able to counteract cortisol's antiapoptotic effects, enhancing chemotherapy's efficacy. A previous phase 2 study has shown that adding intermittently dosed relacorilant, a selective GR modulator, to nab-paclitaxel improved outcomes, including progression-free survival (PFS) and overall survival (OS), with minimal added toxicity, in women with recurrent platinum-resistant ovarian cancer. The ROSELLA study aims to confirm and expand on these findings in a larger population. Methods: ROSELLA is a phase 3, randomized, 2-arm, open-label, global multicenter study in women with recurrent, platinum-resistant, high-grade serous epithelial ovarian, primary peritoneal, or fallopian tube cancer. Eligible participants have received 1 to 3 lines of prior systemic anticancer therapy, including ≥1 prior line of platinum therapy and prior treatment with bevacizumab, with documented progressive disease or intolerance to the most recent therapy. There is no biomarker-based requirement for participant selection. Participants are randomized 1:1 to receive intermittently dosed relacorilant in combination with nabpaclitaxel or nab-paclitaxel monotherapy. The study's primary efficacy endpoint is PFS as assessed by blinded independent central review. Secondary efficacy endpoints include OS, investigator-assessed PFS, objective response rate, best overall response, duration of response, clinical benefit rate at 24 weeks, and cancer antigen 125 response. The study is also evaluating safety and patient-reported outcomes. [ABSTRACT FROM AUTHOR]

Objective Measles immunity testing, unlike that for rubella, is not currently part of prenatal screening even though immunity to both is conferred by the measles–mumps–rubella (MMR) vaccine. Although endemic transmission of measles was declared eliminated in the United States in 2001, outbreaks have continued to occur. Given the risks associated with measles infection during pregnancy, we sought to identify risk factors for measles nonimmunity (MNI) in rubella-immune (RI) pregnant individuals. Methods We performed a retrospective observational cross-sectional study of patients receiving prenatal care and delivering at two university hospitals and a county hospital in Southern California from April 1, 2019 to February 1, 2021. Inclusion criteria were pregnant individuals ≥18 years old who had serological testing for rubella and measles during pregnancy. Demographic data were extracted from electronic medical records, including results of serological testing and chronic medical conditions. All subjects were rubella immune, and we compared measles-immune (MI) with MNI groups. Results In total, 1,813 RI individuals were identified, with 1,467 (81%) MI and 346 (19%) MNI individuals. Variables associated with an increased risk of MNI included having public health insurance (adjusted relative risk [aRR]: 1.56; 95% confidence interval [CI]: 1.24, 1.97) and Hispanic ethnicity (aRR: 1.37; 95% CI: 1.06, 1.78). Black race was associated with a decreased risk of MNI (aRR: 0.52; 95% CI: 0.29, 0.91). Birth year before 1989 demonstrated a trend toward increased risk of MNI, but this did not reach statistical significance (aRR 1.23; 95% CI: 1.00, 1.52). No differences were seen between the two groups for medical comorbidities. Conclusion Our study is the first to demonstrate risk factors for measles MNI in patients with documented rubella immunity. In the absence of universal measles serological screening recommendations, the risk factors identified could help guide clinicians in selective screening for those at risk of needing postpartum MMR vaccination. Key Points The rate of measles nonimmunity is higher than previously reported. Hispanic ethnicity and use of public insurance are risk factors for measles nonimmunity. The current recommendation for history-based screening for measles immunity is likely insufficient. [ABSTRACT FROM AUTHOR]

To identify the clinical characteristics that may predict the diagnosis of Rubella virus (RV) or Cytomegalovirus (CMV) among cases of chronic treatment resistant or steroid dependent unilateral anterior uveitis (AU). Thirty-three consecutive patients with a diagnosis of CMV and 32 patients with RV chronic AU were enrolled. The respective frequency of certain demographic and clinical characteristics was compared between the two groups. The presence of abnormal vessels in the anterior chamber angle (75% and 6.1%, respectively, p <.001), vitritis (68.8%–12.1%, p <.001), iris heterochromia (40.6%–15.2%, p =.022) and iris nodules (21.9%–3%, p =.027) were more common among RV AU. Conversely, intraocular pressure greater than 26 mmHg was more commonly encountered in CMV associated AU (63.6%–15.6%, respectively, p <.001) and large keratic precipitates were detected only in CMV-associated AU. RV- and CMV-induced chronic AU differ significantly in the prevalence of specific clinical characteristics. [ABSTRACT FROM AUTHOR]

Vaccine prevention strategies play a crucial role in the management of people living with HIV (PLWH). The aim of this study was to assess vaccination coverage and identify barriers to vaccine uptake in PLWH in the Paris region. A cross-sectional survey was conducted in PLWH in 16 hospitals in the Paris region. The vaccination status, characteristics, opinions, and behaviors of participants were collected using a face-to-face questionnaire and from medical records. A total of 338 PLWH were included (response rate 99.7 %). The median age of participants was 51 years (IQR: 41–58). Vaccination coverage was 77.3 % for hepatitis B (95 % CI: 72.3–81.8 %), 62.7 % for hepatitis A (57.3–67.9 %), 61.2 % for pneumococcal vaccines (55.8–66.5 %), 56.5 % for diphtheria/tetanus/poliomyelitis (DTP) (51.0–61.9 %), 44.7 % for seasonal influenza (39.3–50.1 %), 31.4 % for measles/mumps/rubella (26.4–36.6 %) and 38.5 % for meningococcal vaccine (13.9–68.4 %). The main reason for vaccine reluctance was related to the lack of vaccination proposals/reminders. The overall willingness to get vaccinated was 71.0 % (65.9–75.8 %). In the multivariable analysis, several factors were associated with a higher vaccine uptake; for DTP vaccine: higher education level, having vaccination records, being registered with a general practitioner; for seasonal influenza vaccine: age > 60 years, higher education level, being employed. The overall vaccination coverage was suboptimal. Development of strategies reducing missed opportunity to offer vaccines is needed. [ABSTRACT FROM AUTHOR]

Elimination of malaria has become a United Nations member states target: Target 3.3 of the sustainable development goal no. 3 (SDG3). Despite the measures taken, the attainment of this goal is jeopardized by an alarming trend of increasing malaria case incidence. Globally, there were an estimated 241 million malaria cases in 2020 in 85 malaria-endemic countries, increasing from 227 million in 2019. Malaria case incidence was 59, which means effectively no changes in the numbers occurred, compared with the baseline 2015. Jennifer Doudna—co-inventor of CRISPR/Cas9 technology—claims that CRISPR holds the potential to lessen or even eradicate problems lying in the centre of SDGs. On the same note, CRISPR/Cas9-mediated mosquito-targeting gene drives (MGD) are perceived as a potential means to turn this trend back and put momentum into the malaria elimination effort. This paper assessed two of the critical elements of the World Health Organization Genetically modified mosquitoes (WHO GMM) Critical Pathway framework: the community and stakeholders' engagement (inability to employ widely used frameworks, segmentation of the public, 'bystander' status, and guidelines operationalization) and the regulatory landscape (lex generali, 'goldilocks dilemma', and mode of regulation) concerning mosquito-oriented gene drives (MGD) advances. Based on the assessment findings, the author believes that CRISPR/Cas-9-mediated MGD will not contribute to the attainment of SDG3 (Target 3.3), despite the undisputable technology's potential. This research pertains to the state of knowledge, legal frameworks, and legislature, as of November 2022. [ABSTRACT FROM AUTHOR]

Background: Chikungunya virus (CHIKV) and O'nyong nyong virus (ONNV) are phylogenetically related alphaviruses in the Semliki Forest Virus (SFV) antigenic complex of the Togaviridae family. There are limited data on the circulation of these two viruses in Burkina Faso. The aim of our study was to assess their circulation in the country by determining seroprevalence to each of the viruses in blood donor samples and by retrospective molecular and serological testing of samples collected as part of national measles and rubella surveillance. Methodology/Principal findings: All blood donor samples were analyzed on the Luminex platform using CHIKV and ONNV E2 antigens. Patient samples collected during national measles-rubella surveillance were screened by an initial ELISA for CHIKV IgM (CHIKjj Detect IgM ELISA) at the national laboratory. The positive samples were then analyzed by a second ELISA test for CHIKV IgM (CDC MAC-ELISA) at the reference laboratory. Finally, samples that had IgM positive results for both ELISA tests and had sufficient residual volume were tested by plaque reduction neutralization testing (PRNT) for CHIKV and ONNV. These same patient samples were also analyzed by rRT-PCR for CHIKV. Among the blood donor specimens, 55.49% of the samples were positive for alphaviruses including both CHIKV and ONNV positive samples. Among patient samples collected as part of national measles and rubella surveillance, 3.09% were IgM positive for CHIKV, including 2.5% confirmed by PRNT. PRNT failed to demonstrate any ONNV infections in these samples. No samples tested by RT-qPCR. had detectable CHIKV RNA. Conclusions/Significance: Our results suggest that CHIKV and ONNV have been circulating in the population of Burkina Faso and may have been confused with malaria, dengue fever or other febrile diseases such as measles or rubella. Our study underscores the necessity to enhance arbovirus surveillance systems in Burkina Faso. Author summary: Chikungunya virus (CHIKV) and O'nyong nyong virus (ONNV) are transmitted to humans by the bite of mosquitoes; CHIKV by genus Aedes genus and ONNV by Anopheles genus mosquitoes. Diseases caused by these two viruses can be confused with other common infectious pathologies including malaria, dengue fever, measles, and rubella, Prior to 2023, there were limited data on the circulation of CHIKV and ONNV in Burkina Faso. The aim of our study was to assess their circulation in the country by determining their seroprevalence in blood donor samples and by carrying out retrospective molecular and serological tests on samples collected as part of national measles and rubella surveillance. Among the blood donor specimens, 56.48% of samples were IgG-positive for CHIKV and 54.49% were IgG-positive for ONNV. Among patient samples collected as part of national measles and rubella surveillance, 3.09% were IgM positive for CHIKV, including 2.5% confirmed by plaque reduction neutralizing test (PRNT). Our results suggest that CHIKV and ONNV circulated in the population of Burkina Faso and could have been misdiagnosed clinically as malaria, dengue fever or other febrile diseases such as measles or rubella. These results underscore the necessity to enhance arbovirus surveillance systems in the country through appropriate laboratory testing. [ABSTRACT FROM AUTHOR]

TORCH infections usually result in mild maternal morbidity, but may cause severe congenital abnormalities. Therefore, it is important to detect maternal infections, monitor the fetus after the disease has been recognized, and define the seronegative women who are at risk of primary infection during pregnancy. From 2014 to 2023, serum samples from 1032 childbearing-aged and pregnant women (16–45 years) were tested for IgM/IgG antibodies to the most common TORCH pathogens: Toxoplasma gondii, rubella virus (RUBV), cytomegalovirus (CMV), and herpes simplex viruses (HSV-1 and HSV-2). The overall IgG seroprevalence rates were 20.1% for T. gondii, 91.3% for RUBV, 70.5% for CMV, 66.8% for HSV-1, and 3.5% for HSV-2. Only HSV-2 seroprevalence was age-related, with a significant progressive increase in seropositivity from 0% in those aged less than 26 years to 9.3% in those older than 40 years. The seroprevalence of T. gondii was higher in residents of suburban/rural areas than in residents of urban areas (27.4% vs. 17.1%). In addition, participants from continental regions were more often toxoplasma-seropositive than those from coastal regions (22.2% vs. 15.3%). HSV-1 seroprevalence was also higher in suburban/rural areas (71.7% vs. 64.7%). Obstetric history was not associated with TORCH seropositivity. Univariate and multivariate risk analysis showed that suburban/rural areas of residence and continental geographic regions were significant risk factors for T. gondii seroprevalence. Furthermore, suburban/rural area of residence was a significant risk factor for HSV-1 seroprevalence, while older age was a significant risk factor for HSV-2 seroprevalence. A declining trend in the seroprevalence of all TORCH pathogens was observed compared to previous Croatian studies (2005–2011). Similarly, the proportion of women simultaneously IgG-seropositive to two or three pathogens decreased over time. The maternal serology before pregnancy could potentially reduce the burden of congenital TORCH infections. [ABSTRACT FROM AUTHOR]

Introduction: Since the Syrian Civil War began in 2011, the official number of refugees under temporary protection in Turkiye is reported to be 3,522,036 in 2023. Most of the Syrians living outside the refugee camps have worse conditions in terms of access to healthcare centers and social opportunities, compared to those living in camps. The Sanliurfa province hosts the third highest number of Syrians (370,291) in Turkiye. There are no data about the seroprevalence of Toxoplasma gondii (T. gondii), rubella (rub), or cytomegalovirus (CMV) among Syrian refugees in Sanliurfa. We aimed to investigate the seroprevalence of T. gondii, rub, and CMV infections among female Syrian refugees of reproductive age (15-49 years) living in Sanliurfa province. Methodology: A cross-sectional study was conducted in different districts of Sanliurfa. A total of 460 households were selected using the probability sampling method. One married female Syrian refugee aged between 15 and 49 years, was chosen in each household, leading to a sample size of 410 female Syrian refugees. The seropositivity of T. gondii, CMV, and rub IgM and IgG in blood samples were analyzed using enzyme immunoassays (Abbott Architect, Illinois, USA). Results: The seropositivity rates of T. gondii, CMV, and rubella IgM and IgG were 4.4% and 59.8%; 3.9%; and 99%; and 1.9%, and 99.5%, respectively. Conclusions: A screening program should be implemented for T. gondii, CMV, and rub infections for Syrian refugees. Seronegative women should be vaccinated against rub and educated about the transmission and preventive routes of toxoplasmosis and CMV infection. [ABSTRACT FROM AUTHOR]

Objective: Toxoplasma gondii, rubella, and cytomegalovirus (CMV) are among the TORCH (Toxoplasma, Others, Rubella, Cytomegalovirus, Herpes simplex virus) group microorganisms. Knowing regional epidemiological data on TORCH group infections is important, especially when deciding whether to perform routine screening at the regional and national levels. Our study aimed to evaluate the frequency of T. gondii, rubella, and CMV IgM and/or IgG antibodies in female patients admitted to a state hospital in İstanbul. Method: T. gondii, rubella, and CMV IgG and IgM antibody results tested in patient sera between January 2017 and December 2020 were evaluated retrospectively. Results: The results of 33 636 samples were evaluated. The highest rate of seropositivity was detected in the 20-29 age group (n=4626, 26.72%). The highest of antibody positivity was reported in 2019 (33.29%). The IgG seropositivity rate was 24.1% for T. gondii, 93.5% for rubella, and 98.3% for CMV. Conclusion: Except for the differences in T. gondii seroprevalence, the results of our study seem to be similar to those of other studies both in our country and globally. The seronegativity rate (74.9%) for T. gondii was high in our research, which indicates that pregnant women should be carefully monitored for T. gondii infection in our region. We conclude that more comprehensive studies are needed to establish national screening programs for TORCH group agents. [ABSTRACT FROM AUTHOR]

This study examines the clinical features and risk factors associated with early mortality in patients with cartilage-hair hypoplasia (CHH), a rare genetic disorder. The study compares data from three international registries and finds that uncontrolled Epstein-Barr virus (EBV) infection is the only factor significantly correlated with early mortality. The study also notes that allogeneic hematopoietic stem cell transplantation (HSCT) was more common in the USIDNET registry, and that the median age at latest follow-up was shortest in the USIDNET cohort. The study concludes that screening for EBV infection and early management of uncontrolled EBV proliferation should be considered in CHH patients. [Extracted from the article]

Human African trypanosomiasis (HAT), or sleeping sickness, continues to be a major threat to human health in 36 countries throughout sub-Saharan Africa with up to 60 million people at risk. Over the last decade, there have been several advances in this area, some of which are discussed in this overview. Due to the concerted efforts of several bodies, including better identification and treatment of cases and improved tsetse fly vector control, the number of cases of HAT has declined dramatically. The clinical heterogeneity of HAT has also been increasingly recognized, and the disease, while usually fatal if untreated or inadequately treated, does not always have a uniformly fatal outcome. Improved methods of HAT diagnosis have now been developed including rapid diagnostic tests. Novel drug treatment of HAT has also been developed, notably nifurtimox–eflornithine combination therapy (NECT) for late-stage Trypanosoma brucei gambiense , oral fexinidazole for early and the early component of the late-stage of T.b. gambiense , and the new oral compounds of the oxaborole group, which have shown considerable promise in field trials. Advances in HAT neuropathogenesis have been steady, though largely incremental, with a particular focus on the role of the blood–brain barrier in parasite entry into the central nervous system and the relevant importance of both innate and adaptive immunity. While the World Health Organization goal of elimination of HAT as a public health problem by 2020 has probably been achieved, it remains to be seen whether the second more ambitious goal of interruption of transmission of HAT by 2030 will be attained.

The article discusses research which evaluated the interference of immunosuppressive treatment with the immunological status against measles and rubella in individuals vaccinated with juvenile localized scleroderma, prior to treatment with synthetic disease-modifying antirheumatic drugs (DMARD). The study measured seroprotection rates and measles and rubella-specific-Immunoglobulin G titres and assessed titres expressed as geometric mean concentrations, as well as antibody status.

Background: Despite several years of LF-MDA implementation, Ghana still has some districts with mf prevalence >1%, partly due to poor treatment coverage levels resulting from non-participation in MDA. To address the challenges, we implemented an Engage & Treat (E&T) and Test & Treat (T&T) strategies for individuals who miss or refuse MDA respectively, in a hotspot district, enabling us to reach many of those who seldom, or never, take part in MDA. This financial cost study was undertaken to analyse data on the LF-MDA, E&T and T&T implementation in 2021 and the financial cost to inform the rollout of the E&T and T&T as mop-up strategies in future LF-MDAs. Methods: This costing study analysed cost data from the 2021 LF-MDA implementation activities carried out by the Neglected Tropical Diseases (NTD) programme of the Ghana Health Service and the SENTINEL study, carried out in Ahanta West district for the two interventions (i.e., E&T and T&T). The 2021 Ghana Population and Housing Census data was used to estimate the LF-MDA-eligible population. The financial cost per person treated was estimated and these costs were applied to the projected population to obtain the financial cost for subsequent years. Results: Implementing MDA mop-up strategies either through the E&T or T&T to improve coverage comes at an additional cost to the elimination goals. For example, in 2024 the projected cost per person treated by the routine LF-MDA is estimated at US$0.83. The cost using the integrated LF-MDA and the E&T, T&T led by the NTD programme or T&T integrated into the health system was estimated at US$1.62, US$2.88, and US$2.33, respectively, for the same year. Despite the increased cost, the proposed combined LF-MDA and mop-up strategies will have a higher estimated population treated for 2024 (i.e., 1,392,211) compared to the routine LF-MDA approach (i.e., 988,470) for the same year. Conclusion: Combining LF-MDA with E&T/T&T mop-up strategies, despite their high costs, may provide NTD Programmes with the options of improving treatment coverage and reaching the LF elimination target sooner, given that the routine LF-MDA alone approach has been implemented for many years with some districts yet to reach the elimination targets. Author summary: In Ghana, despite many years of efforts to eliminate lymphatic filariasis (LF) through mass drug administration (MDA), some districts still have a prevalence of infection above the threshold required to eliminate the disease as a public health problem. This is partly because not everyone in these districts is participating in the MDA program. To tackle this challenge, new strategies called Engage & Treat (E&T) and Test & Treat (T&T) were implemented in a hotspot district. These strategies focus on reaching individuals who either miss or refuse MDA, ensuring that even those who rarely or never participate are covered. A financial cost study was undertaken to analyze the data from LF-MDA, E&T, and T&T implementations in 2021 to understand the financial implications for future LF-MDA efforts. The study looked at the cost data from LF-MDA activities conducted by the Neglected Tropical Diseases (NTD) program of the Ghana Health Service and the SENTINEL study in the Ahanta West district for the E&T and T&T interventions. Population data from the 2021 Ghana Population and Housing Census were used to estimate the LF-MDA-eligible population in the country. The study found that implementing these strategies, either through E&T or T&T, to improve coverage comes with an additional cost to the LF elimination goals. For example, in 2024, the projected cost per person treated by the routine LF-MDA alone is estimated at US$0.83. However, when combining LF-MDA with E&T or T&T, the costs increase to US$1.62, US$2.88, and US$2.33, respectively, for the same year. Despite the higher costs, the combined LF-MDA and mop-up strategies are estimated to treat a larger population in 2024 (1,392,211) compared to the routine LF-MDA approach (988,470) for the same year. In summary, although the combined LF-MDA and mop-up strategies have higher costs, they may offer NTD Programs the option to improve treatment coverage and achieve the LF elimination target sooner. This is particularly important as the routine LF-MDA alone approach has been in place for many years, with some districts still facing challenges in reaching elimination targets.

Background: Health information systems (HIS) are a pivotal element in epidemiological surveillance. In Brazil, malaria persists as a public health challenge, with 99% of its occurrences concentrated in the Amazon region, where cases are reported through the HIS Sivep-Malaria. Recent technological advancements indicate that case notifications can be expedited through more efficient systems with broader coverage. The objective of this study is to analyse opportunities for notification within Sivep-Malaria and explore the implementation of mobile electronic devices and applications to enhance the performance of malaria case notifications and use. Methods: This descriptive study analyses data on malaria-positive cases in the Brazilian Amazon from 2004 to 2022. Malaria Epidemiological Surveillance System (Sivep-Malaria) data were used. The Brazilian Amazon region area is approximately 5 million km2 across nine different states in Brazil. Data entry opportunities were assessed by considering the time difference between the 'date of data entry' and the 'date of notification.' Descriptive statistics, including analyses of means and medians, were conducted across the entire Amazon region, and for indigenous population villages and gold mining areas. Results: Between 2004 and 2022, 6,176,878 new malaria cases were recorded in Brazil. The average data entry opportunity throughout the period was 17.9 days, with a median of 8 days. The most frequently occurring value was 1 day, and 99% of all notifications were entered within 138 days, with 75.0% entered within 20 days after notification. The states with the poorest data entry opportunities were Roraima and Tocantins, with averages of 31.3 and 31.0 days, respectively. For indigenous population villages and gold mining areas, the median data entry opportunities were 23 and 15 days, respectively. Conclusions: In malaria elimination, where surveillance is a primary strategy for evaluating each reported case, reducing notification time, enhancing data quality and being able to follow-up cases through computerized reports offer significant benefits for cases investigation. Technological improvements in Sivep-Malaria could yield substantial benefits for malaria control in Brazil, aiding the country in achieving disease elimination and fulfilling the Sustainable Development Goals.

Many cavity nesters add volatile plants with medicinal properties to their nests. In Australia, eucalyptus and tea-trees are highly volatile plants, which have antiparasitic and antimicrobial properties. Here, we tested whether scents of eucalypt (Eucalyptus polybractea) and tea tree (Melaleuca alternifolia) essential oils can attract birds to newly installed nest boxes. Twenty-four nest boxes received three scent treatments (eucalypt, tea tree, control) for 10 days each using a Latin-square design. Bird visitation was recorded using camera traps. Eastern Rosellas (Platycercus eximius) visited the nest boxes the most (1,454 visits) and were therefore the focus of the study. Eastern Rosellas did not change their behaviours in response to the eucalypt scent in nest boxes: there was no difference in visitation, duration of visits or nest box inspection behaviour between nest boxes with eucalypt scent and those with the control scent. However, Eastern Rosellas visited nest boxes with tea tree scent less frequently and spent less time at these boxes than those with the control scent. The mean time that Eastern Rosellas spent inspecting boxes slightly increased over the 10-day period following scent placement at boxes with control and eucalypt scents, while it sharply decreased at boxes with tea tree scent. This is the first study demonstrating that an Australian bird detected and behaved differently in response to plant volatiles. The use of scents may offer opportunities to not only attract, but potentially also deter certain birds from using particular hollows. [ABSTRACT FROM AUTHOR]

The aim of this study is to determine the seroprevalence of Toxoplasma gondii (T. gondii), rubella and cytomegalovirus (CMV) and the primary infection rates of these agents with avidity test in pregnant women in Muş province. Additionally, the effect of prevention and protection measures implemented during the Covid-19 pandemic on the prevalence of T. gondii, rubella and CMV in pregnant women was also investigated. Between 2018 and 2021, IgG and IgM antibodies in the serum samples of pregnant women who applied to the Department of Gynecology and Obstetrics polyclinic of Muş State Hospital were examined by enzyme-linked immunosorbent assay (ELISA) and chemiluminescence immunoassay (CLIA). High and low avidity assays were examined by enzyme linked fluorescence assay (ELFA). Low seroprevalence of T. gondii IgG antibody (28%) and the detection of low avidity detection in 38 of 102 pregnant women indicate that this parasite may be a risk for intrauterine life. Rubella IgG (89%) and CMV IgG (99%) antibodies were found to carry a low risk due to their high seroprevalence and avidity. It was determined that Covid-19 prevention and protection measures caused a significant decrease in the prevalence of rubella and CMV, but had no effect on the prevalence of T.gondii.

Rash and fever are some of the most common chief complaints present in paediatric dermatology emergencies. The spectrum of differential diagnosis is broad, including many different infectious and some non-infectious agents. A systematic approach involving detailed history taking, careful clinical examination along with particular attention to epidemiological features are the most important factors to make a diagnosis. This article reviews the morphological patterns of various causes of fever with rash in children, including infectious as well as non-infectious causes, with special emphasis on the Indian scenario. We intend to highlight the clinical characteristics of each cause, which will not only help make a clinical diagnosis but also distinguish benign versus life-threatening causes of skin rash in febrile paediatric patients and provide early medical intervention.

Measles is a highly contagious viral disease, and hence, sufficient herd immunity is obligatory to prevent infection transmission. Measles is still a cause of considerable disease burden globally, mainly in children. During a national measles outbreak in Israel in 2018–2019, the peak incidence rates occurred in the Jerusalem district. Most measles cases in the Jerusalem district (75.5%, 1702) were observed in children younger than 15 years of age, 49.2% (1109) were in children under 5 years of age, and 18.9% (425) were in infants under 1 year of age. The routine measles vaccination schedule includes two doses at 1 and 6 years of age. Most cases (1828, 81.1%) were unvaccinated (zero measles vaccine doses). These cases comprised the 425 affected infants under 1 year of age, who were ineligible for vaccination, along with the 1403 children over 1 year of age, who were otherwise unvaccinated. This study aimed to describe the epidemiologic and laboratory features of this measles outbreak, and to investigate case ascertainment (laboratory confirmed compared to epidemiologically confirmed cases). The study population included 2254 measles cases notified during the period spanning June 2018 to May 2019 in the Jerusalem district (incidence rate 176 per 10,000 population). Of the 2254 cases, 716 (31.8%) were laboratory confirmed, and 1538 (68.2%) were confirmed as epidemiologically linked. Most laboratory confirmed cases (420, 58.7%) underwent real-time PCR tests. Serological tests (measles IgM and IgG) were used in 189 (26.4%) cases, and a combination of RT-PCR and serology was used in 107 (14.9%) cases. In a multivariate model analysis, the variables significantly associated (after adjustment) with higher odds for laboratory confirmation included month of disease onset (late), additional measles cases in the household (single case), place of medical treatment (hospital; either emergency department, or hospitalization) and vaccination status (at least one prior vaccine dose). The measles outbreak described demonstrates the urgency of addressing vaccination gaps with appropriate outbreak prevention programs. The road to measles elimination needs to be paved with robust public health infrastructure, excellent field epidemiology for outbreak surveillance, investigation, and control, and laboratory proficiency.

We investigated clinically suspected measles cases that had discrepant real-time reverse transcription PCR (rRTPCR) and measles-specific IgM test results to determine diagnoses. We performed rRT-PCR and measles-specific IgM testing on samples from 541 suspected measles cases. Of the 24 IgM-positive and rRT-PCR-negative cases, 20 were among children who received a measlescontaining vaccine within the previous 6 months; most had low IgG relative avidity indexes (RAIs). The other 4 cases were among adults who had an unknown previous measles history, unknown vaccination status, and high RAIs. We detected viral nucleic acid for viruses other than measles in 15 (62.5%) of the 24 cases with discrepant rRT-PCR and IgM test results. Measles vaccination, measles history, and contact history should be considered in suspected measles cases with discrepant rRTPCR and IgM test results. If in doubt, measles IgG avidity and PCR testing for other febrile exanthematous viruses can help confirm or refute the diagnosis. [ABSTRACT FROM AUTHOR]

A pregnant woman was diagnosed with Rubella re-infection in Northern Cyprus. The patient was unaware of her pregnancy when she sought medical attention for the pain, stiffness, and numbness in the fingers and hand joints without the presence of a rash. Following the confirmation of pregnancy as part of a routine check, Rubella IgM and Rubella IgG antibodies were assessed. Her Rubella IgM was in the grey zone reference units of the tests performed with the presence of Rubella IgG supporting and reinfection. Thus, further Rubella IgG avidity and Western blot were performed. Rubella IgG avidity was borderline. Hence, abortion was advised following the test results. Post-abortion, the Rubella IgM antibodies remained persistent for over 12 months. [ABSTRACT FROM AUTHOR]

Transposable elements (TEs) are prevalent components of diverse genomes, and play an important role on the genomic stability and expression regulation of their adjacent genes. It is interesting to know the variation of TE expression and the effects of the presence/absence of TEs on gene expression after hybridization. Here we assessed the expression variation of TEs and the impacts of TEs on expression of nearby genes after hybridization based on comparisons of three pairs of reciprocal F1 hybrids and four parents in Capsella rubella. Of the 480 TE families expressed in all the four parents and six F1 hybrids, 7–23 (1.5%–4.2%) TE families were significantly differentially expressed between in silico and real F1 hybrids, indicating the expression levels of these TE families were affected during hybridization. In particular, there was a Copia TE superfamily and a non‐long terminal repeat (non‐LTR) TE differentially expressed between the reciprocal F1 hybrids of 879 and 86IT1, indicating maternal effects may have impacts on expression of TEs in these F1 hybrids. Besides the impacts on the expression of TE families of the hybridization, genes adjacent to polymorphic TEs tended to show a higher proportion (24.83%) of allele‐specific expression (ASE) in F1 hybrids. Overall, our results highlight the impacts of hybridization on the expression level variation of TEs, and the effects of TEs on ASE after hybridization. [ABSTRACT FROM AUTHOR]

• MMR vaccinated children had lower rates of antibiotic treatments than children with no MMR. • Bias may explain at least some of the observed association. • Limited non-specific effects of MMR vaccine on infections treated out-of-hospital. Previous studies have shown that vaccination against measles, mumps, and rubella (MMR) may have beneficial non-specific effects, reducing the risk of infections not targeted by the vaccine. We investigated if MMR vaccine given after the third dose of diphtheria-tetanus-acellular pertussis vaccine (DTaP3), was associated with reduced rates of antibiotic treatments. Register-based cohort study following children from the age of recommended MMR vaccination until age 2 years. We included 831,287 children born in Denmark, Finland, Norway, and Sweden who had received DTaP3 but not yet MMR vaccine. Cox proportional hazards regression with age as the underlying timescale and vaccination status as a time-varying exposure was used to estimate covariate-adjusted Hazard Ratios (aHRs) and inverse probability of treatment weighted (IPTW) HRs of antibiotic treatments. Summary estimates were calculated using random-effects meta-analysis. Compared with only having received DTaP3, receipt of MMR vaccine after DTaP3 was associated with reduced rates of antibiotic treatments in all countries: the aHR was 0.92 (0.91–0.93) in Denmark, 0.92 (0.90–0.94) in Finland, 0.84 (0.82–0.85) in Norway, and 0.87 (0.85–0.90) in Sweden, yielding a summary estimate of 0.89 (0.85–0.93). A stronger beneficial association was seen in a negative control exposure analysis comparing children vaccinated with DTaP3 vs two doses of DTaP. Across the Nordic countries, receipt of MMR vaccine after DTaP3 was associated with an 11% lower rate of antibiotic treatments. The negative control analysis suggests that the findings are affected by residual confounding. Findings suggest that potential non-specific effects of MMR vaccine are of limited clinical and public health importance for the milder infections treated out-of-hospital in the Nordic setting.

Background: It is unclear whether patients with basal ganglia calcifications (BGC) should undergo infectious disease testing as part of their diagnostic work-up. We investigated the occurrence of possibly associated infections in patients with BGC diagnosed with Fahr's disease or syndrome and consecutively performed a systematic review of published infectious diseases associated with BGC. Methods: In a cross-sectional study, we evaluated infections in non-immunocompromised patients aged ≥ 18 years with BGC in the Netherlands, who were diagnosed with Fahr's disease or syndrome after an extensive multidisciplinary diagnostic work-up. Pathogens that were assessed included the following: Brucella sp., cytomegalovirus, human herpesvirus type 6/8, human immunodeficiency virus (HIV), Mycobacterium tuberculosis, rubella virus, and Toxoplasma gondii. Next, a systematic review was performed using MEDLINE and Embase (2002–2023). Results: The cross-sectional study included 54 patients (median age 65 years). We did not observe any possible related infections to the BGC in this population. Prior infection with Toxoplasma gondii occurred in 28%, and in 94%, IgG rubella antibodies were present. The positive tests were considered to be incidental findings by the multidisciplinary team since these infections are only associated with BGC when congenitally contracted and all patients presented with adult-onset symptoms. The systematic search yielded 47 articles, including 24 narrative reviews/textbooks and 23 original studies (11 case series, 6 cross-sectional and 4 cohort studies, and 2 systematic reviews). Most studies reported congenital infections associated with BGC (cytomegalovirus, HIV, rubella virus, Zika virus). Only two studies reported acquired pathogens (chronic active Epstein–Barr virus and Mycobacterium tuberculosis). The quality of evidence was low. Conclusions: In our cross-sectional study and systematic review, we found no convincing evidence that acquired infections are causing BGC in adults. Therefore, we argue against routine testing for infections in non-immunocompromised adults with BGC in Western countries. [ABSTRACT FROM AUTHOR]

• Country ownership is one of the four guiding principles for the Immunization Agenda 2030. • There is little practical guidance on what country ownership is and how to operationalize it. • Measles and rubella programs are used to illustrate country ownership in operation. • Five elements of country ownership - commitment, coordination, capacity, community participation, and accountability - are described. • Our work is a useful guide for immunization program strategy development. Country-owned, as opposed to donor-driven, is a principle within the development sector that recognizes the centrality of countries' leadership, systems, and resources in executing programs and achieving sustainable development. In alignment with this notion, the Immunization Agenda 2030 was developed with country ownership as one of four core principles of the ambitious ten-year plan. This means that the success of immunization programs, including those with eradication and elimination goals such as polio, measles, and rubella, and those with broader equity goals to "leave no one behind" on immunization, would be largely driven by country systems. In this paper we deconstruct country ownership into five operational principles: commitment, coordination, capacity, community participation, and accountability. Through this lens, we illustrate how two countries, Nepal and Nigeria, have exemplified country ownership in their measles and rubella elimination programs and we infer the ways in which country ownership drives system performance and sustains program efforts.

China has been working towards measles elimination, but in 2017, measles outbreaks occurred in Ganzi and Aba prefectures of Sichuan province, representing 95% of all provincial cases and jeopardizing measles elimination. During March and April 2017, high-performing prefectures were paired with outbreak and other interested counties to jointly conduct a measles-rubella (MR) catch-up campaign, build population immunity, and strengthen the counties' programs. House-to-house search identified 88,383 children in Ganzi that lacked MCV vaccination; 85,144 (96.34%) were vaccinated. Search identified 33,683 children in Aba who were not vaccinated against measles; 33,074 (98.19%) were vaccinated. The supporting prefectures helped install Immunization Information Systems and enroll unvaccinated children into the immunization program.The outbreak ended within a month and incidence has remained low for the subsequent six years. A paired catch-up campaign represents an effective model of using measles elimination strategies to strengthen local immunization programs for long-term program effectiveness. [ABSTRACT FROM AUTHOR]

Measles, a highly contagious disease primarily affecting children, carries serious health risks, including complications and mortality. Vaccination remains the most effective preventive measure against measles transmission. The COVID-19 pandemic has exacerbated challenges in surveillance and immunization efforts, leaving millions of people exposed to preventable diseases such as measles. Globally accelerated immunization campaigns are critical for achieving regional elimination goals and mitigating the risk of outbreaks. Our team has developed an open-access database for global measles monitoring, facilitating standardized data collection and analysis. The analysis of measles cases from 2011 to 2023 reveals fluctuating trends, with notable increases in Africa in 2019 and 2023, indicating potential gaps in control strategies. Using an automated signal detection tool developed by the European Centre for Disease Prevention and Control (ECDC) team, we identified significant variations between World Health Organization (WHO) regions, underscoring the importance of continuous monitoring to detect epidemiological changes early. These results underscore the need for robust surveillance systems and accelerated vaccination efforts to safeguard public health. [ABSTRACT FROM AUTHOR]

Twelve species of atyid shrimps are reported from three Micronesian islands (Babeldaob, Pohnpei, and Guam) and studied using a combined morphological and molecular approach. Among them, three are new records for the area (Caridina appendiculata, Caridina lobocensis, and Caridina rubella), while three new species are here described: Atyoida chacei sp. nov., Caridina ponapensis sp. nov., and Caridina rintelenorum sp. nov. Descriptions for these new species, diagnoses for poorly known species, and taxonomic notes are provided herein and their biogeography is discussed. [ABSTRACT FROM AUTHOR]

Hibiscus sabdariffa L. (Rosella) has a long history of use in food preparation, herbal remedies, hot and cold beverages, food industry flavoring, and herbal drinks. More than 300 species of Hibiscus are grown all over the world. It is an annual herbaceous shrub belonging to the family Malvacea. However, limited is known about the antimicrobial properties of H. sabdariffa; the purpose of this study was to investigate the antimicrobial activity of H. sabdariffa (Rosella) extract against a range of pathogens, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans. The results of the study showed that H. sabdariffa (Rosella) extract had a significant antimicrobial effect, against S. aureus and E. coli. Further the minimum inhibitory concentration (MIC) shows 128 µg/mL concentration followed by E. coli 256 µg/mL. The biocompatibility of crude metabolites shows highly compatible with Red blood cells (RBC's). This finding suggests that the crude metabolites of H. sabdariffa (Rosella) could be the source to control the human pathogens. [ABSTRACT FROM AUTHOR]

• Proactive recommendations by obstetricians play a key role in the implementation of vaccination in pregnancy but is still insufficient in our setting. • Future efforts should aim to explore possible hurdles that impede recommendations by obstetricians for vaccination in pregnancy. • Local campaigns do not seem effective enough to increase vaccination in pregnancy, therefore national campaigns with new strategies are desirable. Pertussis and influenza are endemic infections and associated with relevant morbidity and mortality in newborns and young infants. The Swiss Federal Office of Public Health has recommended influenza vaccination since 2011 and pertussis vaccination in pregnancy (ViP) since 2013 and expanded to repetition in each pregnancy since 2017. ViP is safe and effective in preventing severe diseases, but implementation is a challenge. We hypothesized that the proportion of women receiving ViP is persistently low despite existing national recommendations. Our primary objective was to compare the proportion of pertussis and influenza vaccine recommendations for and its acceptance by pregnant women before and after an information campaign tailored to obstetricians. Secondly, we aimed to identify reasons for missing or declining ViP. We conducted a prospective, single-center, single-arm implementation study in the maternity ward at the University Women's Hospital Basel. We performed standardized interviews with women hospitalized for postpartum care before (October to December 2019, Phase 1, n = 262) and after an information campaign (October to December 2020, Phase 2, n = 233) and compared categorical variables using chi-squared or Fisher's exact test and continuous variables using Whitney Mann U test. We found no significant differences in the proportion of recommendation for pertussis ViP (80 % vs. 84 %, p = 0.25) and implementation (76 % vs. 78 %, p = 0.63) between Phase 1 and 2. Main reasons for missing or declining vaccinations were lack of recommendation (62.8 %) and safety concerns regarding the unborn child (17.7 %). In contrast, the proportion of recommendation for influenza ViP (45 % vs. 63 %, p < 0.001) and implementation (29 % vs. 43 %, p < 0.001) increased significantly. Proactive recommendations by obstetricians play a key role in the implementation of ViP but is still insufficient in our setting. We believe that future efforts should aim to explore possible hurdles that impede recommendations by obstetricians for ViP. The focus should be on the needs and experiences of obstetricians in private practice, but also other health care professionals involved in care of pregnant women. Local campaigns do not seem effective enough, therefore national campaigns with new strategies are desirable. [ABSTRACT FROM AUTHOR]

Background: In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose. Methods and findings: Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign. Campaign coverage was estimated based on home-based immunization record or caregiver recall. Campaign coverage was stratified by child- and household-level risk factors and descriptive analyses were performed to assess reasons for not receiving the campaign dose. Three thousand three hundred and fifty-seven children aged 9 months to 15 years at the time of the campaign were enrolled. Campaign coverage among children aged 9 months to 5 years documented or by recall ranged from 74.2% in Kanpur Nagar District to 90.4% in Dibrugarh District, Assam. Similar coverage was observed for older children. Caregiver awareness of the campaign varied from 88.3% in Hoshiarpur District, Punjab to 97.6% in Dibrugarh District, Assam, although 8% of children whose caregivers were aware of the campaign were not vaccinated during the campaign. Failure to receive the campaign dose was associated with urban settings, low maternal education, and lack of school attendance although the associations varied by district. Conclusion: Awareness of the MR vaccination campaign was high; however, campaign coverage varied by district and did not reach the elimination target of 95% coverage in any of the districts studied. Areas with lower coverage among younger children must be prioritized by strengthening the routine immunization programme and implementing strategies to identify and reach under-vaccinated children.

Ghana witnessed an outbreak of measles in 2022 following the COVID-19 pandemic, and Savannah Region was among the regions severely impacted. The objective of this study was to conduct trend analysis of measles case incidence and measles-rubella (MR) vaccination coverage in the Savannah Region to identify gaps and propose remedial actions to mitigate future outbreaks of vaccine preventable diseases (VPDs). Analysis of measles surveillance and measles-rubella vaccination data for 2018–2022 was conducted to assess relationship between immunization coverage and measles case incidence. Data were extracted from the District Health Information Management System (DHIMS) platform and loaded into Microsoft Excel 16.0 spreadsheet for analysis. Coverages for first (MR1) and second (MR2) doses of measles-rubella vaccination, dropout rates, and measles incidence (per 100,000) were calculated. The coverage trend for both vaccine doses followed similar trajectories, increasing from 2018 to a peak in 2019, and declining sequentially thereafter to the lowest (for the study period) in 2022. Generally, MR1/MR2 dropout rate was high across all districts during the entire study period. The regional incidence of confirmed measles rose sharply from less than 1/1,000,000 in 2018–2021 to 94 in 2022. Wide variations in vaccination coverage and dropout rates were observed among the districts. There was moderate to fairly strong negative correlation between MR vaccination coverage and measles case incidence. The MR vaccination coverage in the Savannah Region declined probably due to pre-existing weaknesses in the immunization programme accentuated by impact of the COVID-19 pandemic. The lowered population immunity likely contributed to occurrence of the measles outbreak in 2022. Pragmatic actions are needed to catch-up on missed children, restore coverage to pre-pandemic levels, and strengthen the immunization programme as part of global efforts towards achieving the Immunization Agenda 2030 (IA2030) trajectory.
