Observational study to assess pregnant women's knowledge and behaviour to prevent toxoplasmosis, listeriosis and cytomegalovirus

Knowledge Gaps and Educational Opportunities in Congenital Toxoplasmosis: A Narrative Review of Brazilian and Global Perspectives

Congenital toxoplasmosis is a parasitic disease caused by the transmission of the protozoan Toxoplasma gondii during pregnancy that can potentially cause severe consequences for the fetus or neonates. The disease disproportionately impacts the global population and is generally correlated with the Human Development Index. Despite its prevalence, there are knowledge gaps among pregnant women and healthcare providers regarding the prevention, diagnosis, and treatment of this condition. This narrative review aimed to examine the current state of knowledge of toxoplasmosis among both groups, with a focus on exploring the Brazilian and global perspectives and highlighting opportunities for enhancing education and communication. A search was conducted across five databases, and 60 studies were selected (23 in Brazil and 37 worldwide). Quantitative analysis revealed that general knowledge of toxoplasmosis among pregnant women is notably poor, with 66% of Brazilian women and 72% of women worldwide lacking sufficient understanding. Among those with some knowledge, the most recognized association is with cats (46% in Brazil and 38% worldwide), followed by raw or undercooked meat (27% in Brazil and 25% worldwide), and improperly sanitized vegetables or water (15% in Brazil and 21% worldwide). Similarly, gaps in knowledge were found among healthcare providers. Difficulty with IgG avidity test interpretation is higher in Brazil (43%) compared to worldwide (18%). The most recognized association is with cats (66% in Brazil and 74% worldwide), followed by raw or undercooked meat (49% in Brazil and 70% worldwide), and improperly sanitized vegetables or water (31% in Brazil and 32% worldwide). These findings emphasize the need for tailored local and global public health educational initiatives to enhance knowledge of toxoplasmosis among pregnant women and healthcare providers.

Ophthalmic Complications, Diagnosis, and Treatment of Congenital Human Cytomegalovirus Infection

Background: Human cytomegalovirus (hCMV) is the most common etiological agent of congenital infections seen in newborns. Among the most commonly observed complications in children with congenital human cytomegalovirus infection are those affecting the visual system. Ocular complications of congenital CMV (cCMV) are a topic rarely addressed in the literature, which prompted the authors to update the available knowledge with the latest data. Methodology: English-language literature published between April 2000 and November 2023 (PubMed, NIH, Google Scholar) was analyzed for ocular complications of cCMV. The data obtained were categorized according to the ocular area involved and the incidence. A compilation of criteria for the symptomatic form of cCMV was also created. Results: The cCMV complications described in the literature affect all parts of the visual system: the anterior segment, the posterior segment, the posterior visual pathways, and the visual cortex. The most commonly described ocular complication of cCMV is choroidal and retinal scarring. Conclusions: Ophthalmic complications of cCMV can cause severe visual disturbances. Ophthalmic diagnosis in newborns should include hCMV PCR testing, which has the highest sensitivity and specificity. In the symptomatic form of cCMV, treatment should be instituted according to recommendations. A consensus should be established for screening of primary hCMV infection in pregnant women, the way in which to define the symptomatic form of cCMV, and the appropriateness and standards of treatment for primary hCMV infection in pregnant women.

Seroinfection of Antibodies to Toxoplasma gondii, Parvovirus B19, Treponema pallidum, and HIV in a Pregnant Attending a Medical Center in Northern Peru

Introduction

Transplacental infections are frequent, especially in developing countries, where limited screening is performed to find infectious agents in the pregnant population. We aim to determine the clinical and epidemiological characteristics and seroinfection of antibodies against Toxoplasma, parvovirus B19, T. pallidum, and HIV in pregnant women who attended the Motupe Health Center in Lambayeque, Peru during July-August 2018.

Methods

A descriptive cross-sectional study was conducted in 179 pregnant women interviewed with a standardized questionnaire. ELISA was used to determine antibodies to Toxoplasma and parvovirus B19. The detection of syphilis and HIV was conducted using immunochromatography, while the detection of hepatitis B was conducted using FTA-ABS and immunofluorescence, respectively.

Results

Of 179 pregnant women, syphilis and HIV infections routinely included in the screening of pregnant women presented a seroinfection of 2.2 and 0.6%, respectively. Toxoplasmosis seroinfection was 25.1%, while IgM antiparvovirus B19 was 40.8%, revealing that pregnant women had an active infection at the time of study.

Conclusion

The level of seroinfection of toxoplasmosis reveals the risk to which pregnant women who participated in the study are exposed. The high seroinfection of parvovirus B19 could explain the cases of spontaneous abortion and levels of anemia in newborn that have been reported in Motupe, Lambayeque, Peru. However, future causality studies are necessary to determine the significance of these findings.

Cross-sectional community-based study to assess the awareness of toxoplasmosis in Saudi Arabia

A few reports have been published and documented low level of awareness on toxoplasmosis among Saudi women. Herein, a cross sectional community based study was undertaken to evaluate basic knowledge on toxoplasmosis among residents in the Eastern province (Sharqiyah). Thisstudy was conducted between December 2022 and January 2023 on 334 females from different ages and educational backgrounds. Analysis of their responses revealed that only (24.9%) had heard about the disease. However, (69.8%) properly identified cats as the source of Toxoplasma gondii (T. gondii), but a smaller percentage (47.7%) knew that they might become infected through handling cat feces, and a few (26.3%) believed that bad hand hygiene can result in T. gondii infection. A few males (n = 26) have also participated, for the first time in Saudi Arabia, and displayed also low level of knowledge on toxoplasmosis. We do recommend establishing educational programs for females, in various Saudi provinces, to raise awareness on toxoplasmosis.

Cytomegalovirus Infection in Pregnancy Prevention and Treatment Options: A Systematic Review and Meta-Analysis

OBJECTIVES

Cytomegalovirus (CMV) infection is a significant health concern affecting numerous expectant mothers across the globe. CMV is the leading cause of health problems and developmental delays among infected infants. Notably, this study examines CMV infection in pregnancy, its management, prevention mechanisms, and treatment options.

METHODS

Specifically, information from the Cochrane Library, PUBMED, Wiley Online, Science Direct, and Taylor Francis databases were reviewed along with additional records identified through the register, the Google Scholar search engine. Based on the search, 21 articles were identified for systematic review.

RESULTS

A total of six randomized controlled trials (RCTs) were utilized for a meta-analytic review. As heterogeneity was substantial, the random effects model was used for meta-analysis. Utilizing the random-effects model, the restricted maximum likelihood (REML) approach, the estimate of effect size (d = -0.479, 95% CI = -0.977 to 0.019, p = 0.060) suggests the results are not statistically significant, so it cannot be inferred that the prevention methods used were effective, despite an inverse relationship between treatment and number of infected cases. The findings indicated that several techniques are used to prevent, diagnose, and manage CMV infection during pregnancy, including proper hygiene, ultrasound examination (US), magnetic resonance imaging (MRI), amniocentesis, viremia, hyperimmunoglobulin (HIG), and valacyclovir (VACV).

CONCLUSIONS

The current review has significant implications for addressing CMV infection in pregnancy. Specifically, it provides valuable findings on contemporary management interventions to prevent and treat CMV infection among expectant mothers. Therefore, it allows relevant stakeholders to address these critical health concerns and understand the effectiveness of the proposed prevention and treatment options.

An Evaluation of Food and Nutrient Intake among Pregnant Women in The Netherlands: A Systematic Review

Nutritional deficiencies during pregnancy can have serious consequences for the health of the (unborn) child. This systematic review provides an updated overview of the available food and nutrient intake data for pregnant women in The Netherlands and an evaluation based on the current recommendations. Embase, MEDLINE, and national institute databases were used. Articles were selected if they had been published since 2008 and contained data on food consumption, nutrient intake, or the status of healthy pregnant women. A qualitative comparison was made with the 2021 Dutch Health Council recommendations and reference values. A total of 218 reports were included, representing 54 individual studies. Dietary assessments were primarily performed via food frequency questionnaires. Protein, vitamin A, thiamin, riboflavin, vitamin B₆, folate, vitamin B₁₂, vitamin C, iron, calcium, and magnesium intakes seemed to be adequate. For folate and vitamin D, supplements were needed to reach the recommended intake. The reasons for concern are the low intakes of fruits, vegetables, and (fatty) fish, and the intakes of alcohol, sugary drinks, and salt. For several foods and nutrients, no or limited intake data were found. High-quality, representative, and recent data are needed to evaluate the nutrient intake of pregnant women in order to make accurate assessments and evaluations, supporting scientific-based advice and national nutritional policies.

Cytomegalovirus seronegativity rate in pregnant women and primary cytomegalovirus infection during pregnancy in rural Germany

BACKGROUND

Congenital cytomegalovirus (CMV) infection is the most common congenital infection worldwide and one of the leading causes of congenital hearing loss in newborns. The aim of this study was to determine the seroprevalence rate for cytomegalovirus in pregnant women and the rate of CMV serological testing utilised during pregnancy in a rural region in Germany.

METHODS

Retrospective data on the prevalence of CMV IgG and IgM antibodies were obtained from 3,800 women, identified in the study group of 19,511 pregnant women from outpatient settings whose samples were collected between 1 and 2014 and 30 April 2018. In addition, the serological CMV status in regards to various billing methods was further analyzed.

RESULTS

Serological CMV tests were performed in 3,800 (19.5%) out of 19,511 pregnant women. 2,081 (54.8%) of these women were CMV seronegative. Among those, seroconversion rate of 0.37-1.42% was identified. A proportion of 2,710 (14.7%) of all 18,460 women with statutory health insurance made use of the CMV testing as an individual health service.

CONCLUSIONS

The low uptake of CMV serological testing in the study population covered indicates low risk awareness among pregnant women and their healthcare professionals. Presented seronegativity rates and routine seroconversion rate, demonstrate importance to improve intervention strategy to prevent feto-maternal CMV transmission.

Primary, Secondary, and Tertiary Prevention of Congenital Cytomegalovirus Infection

Cytomegalovirus infection is the most common congenital infection, affecting about 1% of births worldwide. Several primary, secondary, and tertiary prevention strategies are already available during the prenatal period to help mitigate the immediate and long-term consequences of this infection. In this review, we aim to present and assess the efficacy of these strategies, including educating pregnant women and women of childbearing age on their knowledge of hygiene measures, development of vaccines, screening for cytomegalovirus infection during pregnancy (systematic versus targeted), prenatal diagnosis and prognostic assessments, and preventive and curative treatments in utero.

Factors Influencing Food Safety Education Practices among Obstetricians

Healthcare providers (HCPs) are responsible for educating pregnant women about food safety issues in to prevent infectious diseases; however, few HCPs provide their pregnant women with such information. This study aimed to identify food safety education practices, attitudes and barriers among obstetricians and determine the factors affecting education practices. In this cross-sectional study, 238 obstetricians completed a self-administered questionnaire. Medians with interquartile ranges, frequency, crosstabs test, Mann-Whitney U test, Kruska-Wallis H test, Dunn-Bonferroni post hoc method, and multiple regression were used for data analysis. The study found that obstetricians provide pregnant women with a low amount of food safety information (2.5 ± 0.42, and the top three barriers reported were lack of time (Mdn = 3, IQR = 1), lack of knowledge (Mdn = 3, IQR = 2), and heavy workload (Mdn = 3, IQR = 2). Furthermore, only a few obstetricians were interested in taking food safety education courses (30.2%) and exploring pregnant women's education needs (39.5%). Factors influencing education practices were total experience, lack of knowledge, and lack of time. Obstetricians should be more aware of the need to educate pregnant women about food safety issues. Understanding the influencing factors determined in this study will contribute to the development of an effective education plan to reinforce doctors' food safety education competency.

Food safety knowledge among pregnant women in the United Arab Emirates amid the COVID-19 pandemic

Studies have indicated shortcomings in food safety knowledge and practices among pregnant women in the Arab region. A high-risk group for having severe outcomes from foodborne illnesses. This study aimed to assess self-reported food safety knowledge and practices among pregnant women in the UAE during the COVID-19 pandemic. A total of 354 pregnant women residing in the UAE completed an online survey between October 2021 and January 2022. The questionnaire included socio-demographic information, food safety knowledge, and food practices during the COVID-19 pandemic. Correct answers for food safety knowledge were scored out of 50 and the total score was compared by sociodemographic characteristics. The total mean score for the study population was 26.7 ± 4.6 out of 50. Participants had good knowledge about foodborne diseases (81.3%) and personal hygiene practices (61.8%). While they were least knowledgeable about cross-contamination (43.3%) and temperature control practices (35.8%). Significantly higher knowledge scores were observed with higher levels of education and primigravida women (p<0.05). Knowledge about the COVID-19 virus and its relation to food safety was adequate for most participants. This study infers the need for food safety-related education and training programs to reduce the risk of foodborne disease among this vulnerable group. It also highlights the need to enhance the role of healthcare professionals as trusted sources of information in improving food safety during pregnancy.

Cross-sectional study to assess awareness of cytomegalovirus infection among pregnant women in Germany

BACKGROUND

Study aimed to assess awareness of congenital cytomegalovirus (CMV) infection and its determinants in pregnancy.

METHODS

Cross-sectional survey was conducted in five hospital-based maternity units in Germany. Pregnant women attending the maternity departments completed interviewer/self-administered survey questionnaire. High-risk group was defined according to contact with children under five years of age (at home or at work). Quantitative analyses using multivariable logistic regression were performed.

RESULTS

One thousand two hundred thirty-three pregnant women were included. 48.5% (n = 598) of women reported any knowledge about risk of CMV infection during pregnancy. CMV infection was less known than other infections or diseases (education about toxoplasmosis 95.5% (n = 1,177), listeriosis 60.5% (n = 746). 38% (n = 468) of participants received education about CMV. CMV awareness was associated with the level of education and employment in childcare or medical care. Only 32% (n = 394) of the women made use of serological screening for CMV during pregnancy (individual health service). 40.8% (n = 503) of pregnant women were classified as high-risk group. They had significantly higher knowledge and education about CMV, and msignificantlycant more often use of the serological screening.

CONCLUSIONS

Less than half of pregnant women surveyed were aware of potential risk associated with CMV infection during pregnancy. In our study,one-third third of pregnant women made use of the serological screening for CMV. Regarding the lack of current consensus on the role of serological CMV screening for pregnant women, hygiene preventive measures are the only evidence-based recommendation for pregnant women and knowledge increase could potentially have major public health impact.

Knowledge of cytomegalovirus infection among women in Saudi Arabia: A cross-sectional study

Background

Cytomegalovirus (CMV) is the most common intrauterine congenital infection in humans. Worldwide seropositive rates of CMV are considerably high among women of childbearing age. There is currently no optimal drug treatment nor a vaccine for congenital CMV infection and therefore the best available program to date of prevention is practicing standard hygienic measures. The success of this program relies on women’s knowledge of CMV modes of transmissions, and risk and preventative behaviors.

Objective

The current study aims to assess the awareness and knowledge of CMV infection among women in Saudi Arabia.

Method

In this cross-sectional study, an online self-administered questionnaire was distributed to women 18 years of age or older residing in all regions of Saudi Arabia. The questionnaire included questions to assess awareness of CMV, knowledge of symptoms, transmission, and preventative measures of CMV infection.

Results

Out of the 1004 women who completed the questionnaire, self-reported knowledge of CMV was considerably low with only 82 women (8.17%) having heard of CMV infection. Most women reported learning about CMV from the internet and university. In binary logistic analyses, women pursuing studies in healthcare and those working in health professions, as well as those with undergraduate and graduate college degrees were significantly associated with higher knowledge of CMV. Urban area of residence was significantly associated with lower levels of knowledge of CMV. Among women who reported they had heard of CMV, their knowledge of CMV modes of transmission, symptoms, and preventative measures was considerably low. Regarding the transmission route, 23% reported no knowledge of modes of transmission, 59.75% reported mother-to-child transmission, 48.78% reported sexual intercourse, and 45% reported contact with body fluids of an infected person. Regarding knowledge of symptoms of congenital CMV, mental retardation and death were the most commonly reported clinical presentations.

Conclusion

The current study showed that the overall knowledge of CMV is very low among women in Saudi Arabia. Working in the healthcare field and higher education levels were significantly associated with better knowledge of CMV. It is crucial that women are provided with information regarding CMV-associated complications and preventative measures against mother-to-fetus transmission of CMV.

Food safety knowledge and risk perception among pregnant women: A cross-sectional study in Jordan during the COVID-19 pandemic

Background

Pregnant women are at a higher risk of food poisoning compared to the general population. This can be detrimental to both the mother and the fetus. This study aimed to assess the level of knowledge and risk perception of basic food safety and handling among pregnant women in Jordan amid the COVID-19 pandemic.

Methods

A descriptive cross-sectional quantitative study among pregnant women in Jordan was conducted using an online questionnaire between November 2020 and January 2021. The survey included socio-demographic data, food safety knowledge, and risk perception questions as well as COVID-19 related questions. A total score for food safety awareness out of 50 was derived for each participant based on the sum of scores from all domains. Student t-test and Analysis of Variance (ANOVA) were conducted using SPSS (Version 26) to compare the mean sum of correct responses of every section (knowledge score) by sociodemographic characteristics.

Results

A total of 325 participants completed the web-based survey. Most of the participants reported receiving food safety-related information during pregnancy (64.9%). The mean total score for the participants was 23.3 ± 4.6 out of 50 (score percentage 46.6%). Participants were mostly aware of foodborne diseases (82.7%) followed by cleaning and sanitation (51.2%), and personal hygiene (49.1%). The least amount of awareness was observed in the cross-contamination (35.0%), food consumption and safety (35.0%), and temperature control (32.8%) domains. Older participants and those with higher education had significantly higher mean scores (p &lt; 0.001). Most participants agreed that the pandemic had a positive impact on enhancing the measures taken to maintain food safety during the pandemic.

Conclusions

This study identified gaps in food safety-related knowledge. Educational programs for pregnant women need robust reinforcement within the community. Efficient educational approaches related to food safety should be provided by health care providers and local health authorities. While the COVID-19 pandemic persists, pregnant women must be well-educated about the virus and its prevention strategies to avoid being infected and ensure their baby's safety as well as their own.

Awareness and knowledge of congenital cytomegalovirus infection among pregnant women and the general public: a web-based survey in Japan

Background

The best approach to reduce congenital cytomegalovirus infection (cCMVi) is to practice behaviors that reduce cytomegalovirus (CMV) transmission during pregnancy. Expanding awareness and knowledge of CMV is expected to result in increased practice of preventative behaviors. To this end, it is necessary to understand current awareness and knowledge of CMV.

Methods

This web-based cross-sectional survey assessed the awareness and knowledge of cCMVi among pregnant women and the general public in Japan. Participants aged 20–45 years (pregnant and non-pregnant women, and men) were identified from a consumer panel. Study outcomes (all participants) included awareness of cCMVi and other congenital conditions. Among those aware of cCMVi, outcomes included knowledge of CMV transmission routes, long-term outcomes of cCMVi, and behaviors to prevent CMV transmission during pregnancy. Outcomes limited to pregnant women included the practice of preventative behaviors and opinion on how easy it is to implement these behaviors. The data of the pregnant group (pregnant at the time of the survey) were compared with those of the general group (non-pregnant women and men).

Results

There were 535 participants in the pregnant group and 571 in the general group. Awareness of cCMVi was generally low (pregnant, 16.1%; general, 10.2%). Pregnant participants were significantly more aware of most congenital conditions than those in the general group, including cCMVi (P = 0.004). Knowledge about CMV/cCMVi was limited; there were no significant differences between the two groups for 24 of the 26 knowledge questions. A small proportion (one third or less) of pregnant women practiced behaviors to prevent the transmission of CMV, though most (73.3–95.3%) pregnant women who were aware of cCMVi considered such behaviors easy to implement.

Conclusions

Awareness and knowledge of CMV/cCMVi is low among pregnant women in Japan; the level of knowledge is similar to that among the general public. This needs to be improved. Most pregnant women considered behaviors to prevent CMV transmission easy to perform, which indicates that effectively educating pregnant women regarding the long-term outcomes of cCMVi, CMV transmission routes, and preventative behaviors will contribute to a reduced incidence of cCMVi.

Simultaneous Seroprevalence to Toxoplasma gondii, Cytomegalovirus and Rubella Virus in Childbearing Women from Western Romania

Background and Objectives: Toxoplasma gondii, cytomegalovirus (CMV) and rubella virus, besides other agents, belong to a group named the TORCH complex. Research on the epidemiology of these agents in women is of particular interest, as primary infection during pregnancy could cause severe damage to the fetus. Women who had contracted infection before pregnancy develop IgG antibodies, so the fetus is protected in case of contact with the same agent. Our scope was to identify the childbearing women simultaneously protected or susceptible to a primary infection to two or three agents mentioned above. Materials and Methods: A cross-sectional study was performed on 6961 fertile Caucasian women from Western Romania, to analyze the simultaneous seroprevalence to two or three of the pathogens from the TORCH complex: Toxoplasma gondii, CMV, and rubella virus. Sampling was conducted at two time points: 2008–2010 (group 1; 1461 participants) and 2015–2018 (group 2; 5500 participants). Results: The percentage of women simultaneously seropositive to IgG-anti-Toxoplasma gondii/IgG-anti-CMV, IgG-anti-Toxoplasma gondii/IgG-anti-rubella, IgG-anti-CMV/IgG-anti-rubella or IgG-anti-Toxoplasma gondii and IgG-anti-CMV/IgG-anti-rubella antibodies decreased between the two groups (2008–2010 vs. 2015–2018): 41.4% vs. 36.1%, OR = 0.79, p = 0.0002; 41.8% vs. 35.7%, OR = 0.77, p < 0.0001; 88.9% vs. 83.6%, OR = 0.63, p < 0.0001; 39.6% vs. 33.2%, OR = 0.75, p < 0.0001. When comparing women from urban and rural areas, the simultaneous seroprevalence was higher in rural areas. In women tested 2008–2010 (group 1) the simultaneous seroprevalence (urban vs. rural) was: 38.4% vs. 49.1%, OR = 1.54, p = 0.0002; 38.4% vs. 50.6%, OR = 1.64, p < 0.0001; 88.8% vs. 89.2%, OR = 1.04, NS; 36.4% vs. 47.7%, OR = 1.58, p = 0.0001. A similar trend was found in women tested in group 2. Conclusions: The rate of simultaneous seropositivity to Toxoplasma gondii, CMV and rubella virus among Romanian women of reproductive age decreased significantly between 2008–2010 and 2015–2018 and the susceptibility to infections increased. It is necessary to apply increased prevention measures among susceptible pregnant women.

Identifying Mobile Health Technology Experiences and Preferences of Low-Income Pregnant Women with Diabetes

BACKGROUND

Rapid expansion of mobile technology has resulted in the development of many mobile health ("mHealth") platforms for health monitoring and support. However, applicability, desirability, and extent of tailoring of these platforms for pregnant women, particularly in populations who experience the greatest health inequities-such as women with diabetes mellitus (DM) and/or those with greater socioeconomic barriers-remains unknown. The objective is to understand low-income pregnant women's experiences and preferences for mHealth tools to support DM health and improve DM self-management during pregnancy.

METHODS

Low-income pregnant and postpartum women were included in individual interviews or focus groups; women with type 2 DM, gestational DM, or no DM were included. Analysis was performed with the constant comparison method.

RESULTS

In this population of 45 (N=37 with DM) low-income, largely minority, pregnant and postpartum women, 100% reported access to smartphones and prior experience with apps. Interest in mHealth to support health and engagement during pregnancy was high. Preferences for general mHealth features included education that reduces uncertainty, support communities, visualizing progress, convenient access to information, and support for better management of pregnancy-related tasks. Preferred design elements included personalization, interactive features, and integrated graphics. Women with DM expressed multiple additional DM-specific needs, including support tools for DM self-management and self-regulation tasks.

CONCLUSION

Pregnant and postpartum women, especially those with DM, desire mHealth technology to support engagement and to adapt lifestyle guidelines and treatment requirements for a healthy pregnancy. Further work to develop mHealth interventions tailored for target populations remains a key step in reducing health inequities and promoting access to evidence-based perinatal health interventions.

Guideline No. 420: Cytomegalovirus Infection in Pregnancy

OBJECTIVE

To provide an update on current recommendations for cytomegalovirus (CMV) infection during pregnancy. The objectives of this guideline are: TARGET POPULATION: Patients of child-bearing age, pregnant patients, and patients planning a pregnancy.

BENEFITS, HARMS, AND COSTS

The patient partners urged us to make awareness of preventive strategies a high priority, despite concern that discussing CMV with patients could cause unnecessary anxiety. CMV educational interventions have shown benefits from increased awareness of cCMV prevalence and preventive strategies among providers, patients, and families.

EVIDENCE

We searched MEDLINE, EMBASE, and CENTRAL databases for CMV in pregnancy. The search terms were developed using MeSH terms and keywords (Appendix). The results were filtered for articles published between January 2010 and October 2020 and systematic reviews, meta-analyses, clinical trials, and observational studies. The main inclusion criteria were pregnant patients and infants, as the target population, and CMV infection, as the diagnosis of interest. Recommendations are graded according to the U.S. Preventive Services Task Force grade of recommendations and level of certainty.

VALIDATION METHODS

We collaborated with patient partners, including members of CMV Canada (cmvcanada.com). In formulating our recommendations, we included patients' voices to add a unique and valuable perspective, thus ensuring that our recommendations are relevant to the patient-provider partnership.

INTENDED AUDIENCE

All perinatal health care providers. RECOMMENDATIONS (GRADE AND LEVEL OF CERTAINTY IN PARENTHESES).

Congenital cytomegalovirus infection: do pregnant women and healthcare providers know enough? A systematic review

BACKGROUND

Cytomegalovirus (CMV) is the most frequent cause of congenital infection worldwide causing serious morbidity in newborns, infants, and children. Despite the clinical importance of congenital CMV (cCMV), studies conducted so far conclude that there is limited awareness in both the medical community and public of cCMV infection. The aim of this systematic review was to assess the knowledge and awareness of cCMV among pregnant women and healthcare providers during the last decade.

METHODS

A literature search was performed in PubMed and Scopus, including studies published between 2011 and 2020. Eligibility criteria included articles focusing on either pregnant women or healthcare providers and reporting data about cCMV awareness. We included cross-sectional and interventional studies. Study quality was assessed using the Study Quality Assessment Tools by National Institute of Health.

RESULTS

Overall, 23 studies fulfilled the inclusion criteria, 13 studies referred to pregnant women and 10 to healthcare providers. A total of 6521 pregnant women and 3609 healthcare providers were included. The level of awareness of pregnant women about cCMV was low to moderate. However, pregnant women showed willingness to adopt hygiene strategies following interventional-educational practices. Concurrently, awareness among healthcare providers varied depending on the specialty. Nonetheless, a great proportion admitted feeling inadequate in advising pregnant women for cCMV screening and prevention.

CONCLUSION

The role of healthcare providers in growing awareness among pregnant women is of paramount importance. Due to the lack of an effective vaccine as yet, education of women regarding hygiene measures is currently the best strategy to prevent cCMV disease.

Pregnant women's knowledge and behaviour to prevent cytomegalovirus infection: an observational study

OBJECTIVES

Congenital cytomegalovirus (cCMV) infection can negatively affect pregnancy outcomes, but may be prevented by simple precautions. Literature suggests that gynaecologists do not always adequately inform about preventive behaviour and most pregnant women have a low-level knowledge regarding cCMV infection. The aim of this study is to evaluate knowledge and risk behaviours related to cCMV infection in an unselected group of pregnant women.

METHODS

An institutional based cross-sectional study was conducted in three Maternal and Fetal Divisions in Rome between November and February 2019 on 296 pregnant women, their knowledge on cCMV was measured using six cytomegalovirus (CMV) related questions.

RESULTS

Out of the 296 respondents, 59.1% had heard, read or seen information about cCMV infection. Regarding the way of transmission, 96/296 (32.4%) correctly recognize children as a potential source of the infection but only 25/296 (8.44%) knew all prevention practices, 28/296 (9.5%) of women reported that they have never performed cCMV test during pregnancy.

CONCLUSIONS

The results of this survey show that knowledge on cCMV infection among pregnant women is poor. This highlights the need to improve counselling on all preventive practices for cCMV infection during perinatal care consultation.

Seroprevalence of ToRCH Pathogens in Southeast Asia

ToRCH is the acronym for several pathogens associated with pregnancy complications and sequelae in the unborn or newborn child. Particularly primary infections during pregnancy are associated with increased risk. Seroprevalence data of ToRCH infections are important, especially in countries with weak disease surveillance systems, to estimate immunity and vaccination levels, as well as exposure rates and thus the risk of infection during pregnancy. A systematic literature search spanning a 30-year time period was conducted to identify serosurveys on ToRCH pathogens in Southeast Asia. The 96 identified studies showed that some pathogens were well studied, while only limited data were available for others. Studies from the better-developed countries of the region were more abundant. Moreover, seroprevalence data were often limited to a certain geographical region within the country or to certain cohorts, there was an evident lack of recent serosurveys, and the study quality was often not adequate. Well-designed and area-wide serosurveys of ToRCH pathogens are clearly warranted. If combined with risk factor analysis, these studies may guide the development and implementation of effective measures for infection prevention, especially during pregnancy. In addition, educational programs for health care workers and for pregnant women during antenatal care are urgently needed.

Cytomegalovirus (CMV) Shedding in French Day-Care Centers: A Nationwide Study of Epidemiology, Risk Factors, Centers' Practices, and Parents' Awareness of CMV

BACKGROUND

Congenital cytomegalovirus (CMV) remains an important healthcare burden, resulting from primary or secondary infection in pregnant women. Exposure to young children's saliva is a major risk factor, as prevalence of CMV shedding can reach 34%.

METHODS

This cross-sectional, multicenter, nationwide study was conducted in randomly selected day care centers (DCCs), and complemented with a survey among parents and DCCs. All children aged >3 months were eligible. The study measured the CMV shedding prevalence in children's saliva and described CMV genotypes epidemiology. The risk factors for CMV shedding and high viral load were evaluated using multivariable models.

RESULTS

A total of 93 DCCs participated. Among the 1770 enrolled children with evaluable samples, the CMV shedding prevalence was 40% (713/1770, 95% confidence interval, 34.6-46.1), independently associated with children aged between 12 and 18 months, history of CMV infection in ≥1 parents, a mid-level income. Prevalence increased with DCC staff workload and attending children number. Viral load was ≥5 log-copies CMV/mL in 48% (342/713). Risk factors for higher viral load included children aged between 12 and 18 months, and still being breastfed. The most frequent genotype combinations were gB1-gN4c-gH2 (6.9%), gB1-gN2-gH2 (6.3%), gB4a-gN3a-gH1 (6.3%), and gB1-gN3b-gH2 (5,7%). CMV awareness was low in parents: their serological status was unknown by 72% of mothers and 82% of fathers. Only 41% knew something about CMV.

CONCLUSIONS

CMV shedding was independently associated with risk factors related to the children, family and DCC. Some of these risk factors may influence prevention strategies, including through an improved information provided to parents.

Control of human toxoplasmosis

Toxoplasmosis is caused by Toxoplasma gondii, an apicomplexan parasite that is able to infect any nucleated cell in any warm-blooded animal. Toxoplasma gondii infects around 2 billion people and, whilst only a small percentage of infected people will suffer serious disease, the prevalence of the parasite makes it one of the most damaging zoonotic diseases in the world. Toxoplasmosis is a disease with multiple manifestations: it can cause a fatal encephalitis in immunosuppressed people; if first contracted during pregnancy, it can cause miscarriage or congenital defects in the neonate; and it can cause serious ocular disease, even in immunocompetent people. The disease has a complex epidemiology, being transmitted by ingestion of oocysts that are shed in the faeces of definitive feline hosts and contaminate water, soil and crops, or by consumption of intracellular cysts in undercooked meat from intermediate hosts. In this review we examine current and future approaches to control toxoplasmosis, which encompass a variety of measures that target different components of the life cycle of T. gondii. These include: education programs about the parasite and avoidance of contact with infectious stages; biosecurity and sanitation to ensure food and water safety; chemo- and immunotherapeutics to control active infections and disease; prophylactic options to prevent acquisition of infection by livestock and cyst formation in meat; and vaccines to prevent shedding of oocysts by definitive feline hosts.

Toxoplasmosis and knowledge: what do the Italian women know about?

Toxoplasmosis is a worldwide zoonotic infectious disease caused by Toxoplasma gondii. This infection is estimated to affect about a third of the world's population. The aim of this study was to evaluate the knowledge of Italian women about toxoplasmosis and its forms of transmission, clinical manifestations, diagnosis and prevention through two different modalities (e-research and traditional research). In a cross-sectional study, 808 Italian women were interviewed, using a self-administered questionnaire, through two different modalities: an e-research or web survey and a traditional paper research and 84% reported to have heard about toxoplasmosis, but from most of the sample, it resulted that the knowledge of the protozoan disease was superficial and incomplete.The assessment of the dimensionality related to the toxoplasmosis knowledge's instrument showed that the scale is composed by two stable and reliable factors which explain 58.6% of the variance: (a) the basic knowledge (α = 0.83), which explains the 45.2% of the variance and (b) the specialist knowledge (α = 0.71), which explains the 13.4% of the variance. The variance and the multiple linear regression data analysis showed significant predictors of correct basic knowledge of toxoplasmosis: the highest age, the highest degree of study, to have previously contracted illness or to know someone who had contracted it, to be working or to be housewives. In conclusion, this study showed limited awareness of toxoplasmosis and suggested the implementation of effective education and learning programs. The results also showed that online data collection, in academic research, might be a valid alternative to more traditional (paper-and-pencil) surveys.

Congenital Cytomegalovirus Infection: Update on Diagnosis and Treatment

Congenital cytomegalovirus (cCMV) infection is the most common congenital viral infection and is the leading non-genetic cause of sensorineural hearing loss (SNLH) and an important cause of neurodevelopmental disabilities. The risk of intrauterine transmission is highest when primary infection occurs during pregnancy, with a higher rate of vertical transmission in mothers with older gestational age at infection, while the risk of adverse fetal effects significantly increases if fetal infection occurs during the first half of pregnancy. Despite its prevalence and morbidity among the neonatal population, there is not yet a standardized diagnostic test and therapeutic approach for cCMV infection. This narrative review aims to explore the latest developments in the diagnosis and treatment of cCMV infection. Literature analysis shows that preventive interventions other than behavioral measures during pregnancy are still lacking, although many clinical trials are currently ongoing to formulate a vaccination for women before pregnancy. Currently, we recommend using a PCR assay in blood, urine, and saliva in neonates with suspected cCMV infection. At present, there is no evidence of the benefit of antiviral therapy in asymptomatic infants. In the case of symptomatic cCMV, we actually recommend treatment with oral valganciclovir for a duration of 12 months. The effectiveness and tolerability of this therapy option have proven effective for hearing and neurodevelopmental long-term outcomes. Valganciclovir is reserved for congenitally-infected neonates with the symptomatic disease at birth, such as microcephaly, intracranial calcifications, abnormal cerebrospinal fluid index, chorioretinitis, or sensorineural hearing loss. Treatment with antiviral drugs is not routinely recommended for neonates with the mildly symptomatic disease at birth, for neonates under 32 weeks of gestational age, or for infants more than 30 days old because of insufficient evidence from studies. However, since these populations represent the vast majority of neonates and infants with cCMV infection and they are at risk of developing late-onset sequelae, a biomarker able to predict long-term sequelae should also be found to justify starting treatment and reducing the burden of CMV-related complications.

Hygiene promotion might be better than serological screening to deal with Cytomegalovirus infection during pregnancy: a methodological appraisal and decision analysis

BACKGROUND

Cytomegalovirus infection is the most frequent viral congenital infection, with possible consequences such as deafness, or psychomotor retardation. In 2016, the French High Council of Public Health was mandated to update recommendations regarding prevention of cytomegalovirus infection in pregnant women. We summarize a critical appraisal of knowledge and deterministic decision analysis comparing the current no-screening situation to serological screening during pregnancy, and to hygiene promotion.

METHODS

Screening was defined as systematic serological testing, during the first trimester, with repeated tests as needed, to all pregnant women. Outcomes were: 1) severe sequela: intellectual deficiency with IQ ≤ 50 or hearing impairment < 70 dB or sight impairment (≤ 3/10 at best eye); 2) moderate sequela: any level of intellectual, hearing or sight deficiency; and 3) death or termination of pregnancy. We simulated the one-year course of cytomegalovirus infection in a cohort of 800,000 pregnant women. We developed a deterministic decision model, using best and min-max estimates, extracted from systematic reviews or original studies.

RESULTS

Relevant data were scarce or imprecise. We estimated that 4352 maternal primary infections would result in 1741 foetal infections, and an unknown number of maternal reinfections would result in 1699 foetal infections. There would be 788 cytomegalovirus-related consequences, including 316 foetal deaths or terminations of pregnancy, and 424 moderate and 48 severe sequelae. Screening would result in a 1.66-fold increase of poor outcomes, mostly related to a 2.93-fold increase in deaths and terminations of pregnancy, not compensated by the decrease in severe symptomatic newborns. The promotion of hygiene would result in a 0.75-fold decrease of poor outcomes, related to both a decrease in severe sequelae among symptomatic newborns (RR = 0.75; min-max: 1.00-0.68), and in deaths and terminations of pregnancy (RR = 0.75; min-max: 0.97-0.68).

CONCLUSIONS

Prevention of cytomegalovirus infection during pregnancy should promote hygiene; serological screening should not be recommended.

Knowledge and attitudes about toxoplasmosis among female university students in Egypt

Aim This study aimed to assess toxoplasmosis-related knowledge, attitudes and preventive practices among female undergraduate students in Beni-Suef University, Egypt. Subjects and methods A cross-sectional design with a multi-stage random sample of female Beni-Suef university students were recruited in this survey over a period of 8 weeks' duration using a self-administrated questionnaire. Results Among 1079 female students, only 35 (3.2%) had good knowledge. Female students of the Health Care faculty and students from rural areas had a significantly higher rate of good knowledge. The results also illustrated that most of the studied sample (63%) had a negative attitude. Nearly one-third of participants were convinced that toxoplasmosis shows symptoms and only (25.6%) agreed about the occurrence of toxoplasmosis infection during pregnancy. A significant positive correlation was found between the total knowledge score and the total attitude score of female students, indicating that students with better knowledge had more positive attitudes. Of the participants, 67.1% always ate fast food, while 70.7%, 72% and 78.2% of female students reported hand washing after gardening, cleaning areas where cats were and cooking with meat, respectively. Conclusion Knowledge regarding toxoplasmosis was deficient among female students attending Beni-Suef University, and they had a negative attitude regarding toxoplasmosis. There was also a positive correlation between students' knowledge and their attitude toward toxoplasmosis infection. Many students avoided risk behaviors in the correct way, without realizing what they avoided. There is a critical need for efficient educational programs to raise the population's awareness regarding toxoplasmosis.

Behavioural factors of Dutch pig producers related to control of toxoplasma gondii infections in pigs

Toxoplasma gondii (T. gondii) is a food safety hazard which causes a substantial human disease burden. Infected pig meat is a common risk source of toxoplasmosis. Therefore, it is important to control T. gondii infections in pigs. Improving farm management to control the introduction risk likely contributes to that aim. A pig producer only implements control measures when he or she is aware of the underlying problem, wants to solve it, and is able to solve it. If a pig producer is not implementing appropriate control measures, behavioural change interventions can be introduced to overcome constraining behavioural factors. To aid in designing behaviour change interventions, this study analysed behavioural factors of Dutch pig producers in terms of capability, opportunity and motivation to control T. gondii infections in pigs. Key risk sources analysed focused on the life cycle of T. gondii, with cats as primary host, rodents as intermediate host, and uncovered feed as an important risk source. A survey was conducted among Dutch pig producers. Responses were analysed using descriptive and cluster analysis. Results showed that around 80% of the 67 responding pig producers was aware of key risk sources of T. gondii infections in pigs. Respondents also rated risk sources that are not known to increase the risk of T. gondii infections in pigs as somewhat important. Many respondents did not know about potential consequences of a T. gondii infection in pigs on human health. Two third expected some impact on pig performance, which is incorrect because T. gondii generally does not make pigs ill. Most respondents indicated to have the motivation and opportunity to control the risk sources cats, rodents and uncovered feed. Three pig producer clusters were identified: one with higher capability to control rodents, one with lower motivation to control rodents and cats and to cover feed storages, and one with lower scores on the importance of rodent control for pigs, human health and farm profit. We conclude that, although many pig producers have knowledge about risk sources for and consequences of T. gondii infections in pigs, the public health impact and risks of T. gondii infections in pigs are not yet common knowledge among all Dutch pig producers. Furthermore, Dutch pig producers differ in opportunity and motivation to control T. gondii infections. Targeted interventions to address these specific constraining behavioural factors can help to improve the control of T. gondii infections in pigs.

Toxoplasmosis knowledge and preventive behavior among pregnant women in the city of Imperatriz, Maranhão, Brazil

The aim of this study was to assess toxoplasmosis knowledge and preventive behavior, and relate these to socioeconomic, pre-natal and environmental issues among pregnant women served by the Family Health Strategy in the municipality of Imperatriz, Maranhão, Brazil. This is a cross-sectional study performed by applying a structured and pre-tested questionnaire to a sample of 239 pregnant women. Only 23.4% of the pregnant women had good knowledge of the disease, primarily in the area of prevention, and 58.9% adopted suitable preventive behaviors. The results obtained show a significant association of various toxoplasmosis risk factors, such as drinking untreated water (OR = 2.1245; IC95% = 1.20-3.73; p = 0.0128), contact with cats (OR = 7.6875; IC95% = 4.22-13.97; p < 0,0001), cleaning cat feces (OR = 6.8738; IC95% = 3.02-15.60; p < 0.0001), eating raw meat (OR = 5.7405; IC95% = 3.21-10.24 and handling sand/cat litter OR = 10.7376; IC95% = 4.64-24.85; p < 0.0001). This shows a need for continued education on toxoplasmosis for the pregnant women seen by the Imperatriz FHS, and for more comprehensive preventive measures, with public health and education policies that take into consideration economic, social, environmental and cultural issues.

Knowledge, attitudes and peer influences related to pregnancy, sexual and reproductive health among adolescents using maternal health services in Ugu, KwaZulu-Natal, South Africa

Background

Knowledge and practices of sexual and reproductive healthcare is pivotal to the Safe Motherhood Initiative; however, only a few studies have investigated adolescent mothers’ knowledge of sexual and reproductive health in light of the above initiative. Research should thus focus on the knowledge and attitudes of adolescent girls as well as peer influences related to pregnancy and sexual and reproductive health among adolescents, as the findings may highlight vital health interventions that should be introduced. The aim of this study was thus to determine the knowledge, personal attitudes and peer influences related to pregnancy, sexual and reproductive health among adolescents who attended maternal health services in a district hospital in Ugu, KwaZulu-Natal, South Africa.

Methods

A cross sectional study was conducted. Data were collected from 326 adolescents who accessed maternal health services in a peri-urban district hospital during June 2017 and November 2017. The questionnaire surveyed the knowledge, personal attitudes and peer influences related to pregnancy, sexual and reproductive health. The questionnaire was administered by fieldworkers using mobile devices powered by the Mobenzi Researcher® technology. The completed surveys were uploaded to the Mobenzi server where it was stored and aggregated. The data was analysed using R software.

Results

Of the 326 participants, 65 (19.9%) experienced repeat pregnancies in adolescence. Overall, only 143 (43.9%) of the participants answered 50% or more of the knowledge questions on pregnancy and HIV/AIDS and STIs correctly, while 183 (56.1%) answered less than 50% of the knowledge questions correctly. There was no relationship between knowledge of pregnancy and HIV/STIs and repeat adolescent pregnancies.

Conclusion

Adolescents’ knowledge of pregnancy and sexual and reproductive health was deficient as, even with repeat pregnancies, these adolescents were evidently no better informed about pregnancy and sexual and reproductive health. This suggests that social determinants, modes and platforms regarding the delivery of adolescent sexual and reproductive health education are important. An innovative mode to the delivery of sexual and reproductive health education includes the emerging digital platform. The digital platform encompasses social media, multimedia and mobile phones which is growing popular among young people.

Investigation of Listeriosis-Related Knowledge, Attitudes, and Practices Among Medical Staff in Fangshan, Beijing, China

The aim of this study was to gain insight into the knowledge of, attitude toward, and practical experience with listeriosis among medical staff. In two hospitals in Fangshan, Beijing, 410 medical staff members were randomly selected using a random sampling method. Each selected staff member was invited to participate in a standardized questionnaire interview. In total, 397 valid questionnaires were collected. With regard to the staff members' general knowledge of listeriosis, they answered 65.96% of the items correctly. The knowledge scores among obstetricians and gynecologists were higher than those of other clinical doctors (p < 0.05); however, obstetricians and gynecologists were less knowledgeable about which drugs are effective against listeriosis than the other doctors (p = 0.007). The percentage of participants with a positive attitude about preventing listeriosis was 96.47%, the percentage with practice formation was 52.39%. The medical staff's mean score for knowledge of listeriosis was 4.61 ± 1.83. The mean score for attitude toward listeriosis was 9.71 ± 1.31. There was a significant association between attitude and knowledge of listeriosis (r = 0.221, p < 0.001). Medical staff obtained a mean score of 2.10 ± 1.07 for the practice formation. There was a significant association between practice formation and knowledge of listeriosis (r = 0.502, p < 0.001). The mean knowledge-attitude-practice (KAP) score for listeriosis among medical staff was 16.41 ± 3.19. The KAP scores were significantly correlated with age (r = 0.129, p = 0.011), occupation (r = -0.103, p = 0.041), department (r = -0.168, p = 0.001), and professional title (r = 0.166, p = 0.001). To improve medical outcomes and foodborne disease surveillance, medical staff should receive more training on listeriosis and the content of the training should be adjusted.

Knowledge and Attitude Regarding Toxoplasmosis among Jazan University Female Students

Background

In Saudi Arabia, the prevalence of toxoplasmosis is high. However, to date, few studies have evaluated the degree of knowledge on toxoplasmosis among females in Saudi Arabia.

Objectives

The objective of this study was to assess the knowledge, attitude and preventive behavior regarding toxoplasmosis among female students at Jazan University, Jazan, southwest Saudi Arabia.

Materials and Methods

This cross-sectional study was conducted on a random sample of 440 female students at Jazan University using a semi-structured, self-administered questionnaire. Data with numerical/qualitative variables were expressed as frequency and percentage. Chi-square test was used to analyze categorical variables. P < 0.05 was used to indicate statistical significance.

Results

This study found that more than three-quarters (79.1%) of the students had insufficient knowledge about toxoplasmosis. Students from healthcare faculties had higher knowledge scores (28.5%) than students from arts and humanities (20.6%) and science (18.9%) faculties; however, the differences were not statistically significant (P = 0.77). The majority of the studied sample (92.3%) was found to eat fast food on a regular basis. About 42%, 54% and 4% of the respondents reported that they never, occasionally and always ate improperly washed vegetables, respectively.

Conclusions

This study found that a substantial proportion of Jazan University's female students have insufficient knowledge on toxoplasmosis. Health educational programs are necessary to increase the awareness and knowledge about toxoplasmosis and its clinical manifestations.

A multicenter survey on toxoplasmosis knowledge among pregnant women in Poland (the TOWER study)

Background

The seroprevalence of Toxoplasma gondii ranges widely in different areas of the world and different populations. Although toxoplasmosis is typically benign and asymptomatic, it induces major complications in immunocompromised individuals and during pregnancy. Prevention of maternal primary infection constitutes the major tool for avoiding congenital T. gondii infections and toxoplasmosis complications. The preventive measures depend on the women’s knowledge about toxoplasmosis. The aim of the study was to assess the knowledge on toxoplasmosis among pregnant women in Poland.

Methods

The study was conducted between October 2016 and January 2017 in 3 Polish cities. During a visit in a hospital outpatient clinic, pregnant women aged > 16 years fulfilled a previously validated questionnaire. The questions concerned personal data (age, parity, educational level, place of residence), toxoplasmosis knowledge (etiology, routes of transmission, symptoms, sequelae), and sources consulted to collect information.

Results

Overall, 465 pregnant women participated in the survey; 439 (94.4%) were aware of toxoplasmosis. Toxoplasmosis was perceived as a zoonotic disease by 77.4%, as a parasitic disease by 41.7%, as a disease transmitted through poor hand hygiene by 8.6%, as a childhood illness by 4%, and as a congenital disease by 0.4%. Regarding the transmission route, 84.5% of women pointed at a domestic cat, 46.7% at eating raw or undercooked meat. The total of 84.3% did not know toxoplasmosis symptoms, and 12.0% stated that they did not present the symptoms. In multivariate analysis, younger age (OR, 2.74; 95% CI, 1.67–4.49; p <  0.001), city residence (OR, 13.45; 95% CI, 3.12–57.89; p <  0.003), and higher education level (OR, 6.81; 95% CI, 3.69–12.59; p <  0.001) were significantly associated with better knowledge of toxoplasmosis, and the number of children (OR, 0.32; 95% CI, 0.22–0.48; p <  0.001) – with higher knowledge of the symptoms.

Conclusions

Among pregnant women in Poland, the basic knowledge on toxoplasmosis is very high (94.4%). Younger age, city residence, higher education level, and the number of children turned out significantly associated with better knowledge of T. gondii and toxoplasmosis symptoms.

Listeriosis in Pregnancy: Practitioners' Food Safety Counselling Practices to Pregnant Women

OBJECTIVE

The relative risk of invasive listeriosis in pregnant women is approximately 20 times greater than the general population, and listeriosis during pregnancy can have negative consequences for pregnant women, their fetuses, and their newborns. Health care providers are valuable sources of information, but published data suggest that most providers are unaware of the risk factors for listeriosis or its propensity for pregnant women, and they do not counsel their pregnant patients about risks. The objective of this study was to determine knowledge and practices of Canadian perinatal care providers on food safety counselling to pregnant women.

METHODS

An anonymous bilingual online questionnaire that sought information about awareness, knowledge of risk factors, practices for counselling pregnant women, and practitioners' learning needs with regard to listeriosis was sent to 3199 nurses, midwives, family physicians, and obstetrician/gynaecologists in Canada, with a response rate of 24.4%.

RESULTS

Most respondents had heard of listeriosis, provided prenatal care, and attended deliveries. Rates of awareness of listeriosis were the same among professions and were independent of years in practice, whether practice was urban or rural, and province. One third of the respondents (35.7%) were aware that listeriosis was more common in pregnant women; a minority (18.7%) correctly identified the incubation period for listeriosis and the stage in pregnancy in which women are at highest risk (30.4%). Those respondents who did not counsel women about the risks of listeriosis during pregnancy reported a lack of information or knowledge as the main reason.

CONCLUSION

Advising pregnant women about behaviours and lifestyle habits to prevent infectious diseases remains important, and information about preventive practices needs to be complete and adequate. The health care providers who participated in this study did express a clear need for information related to food safety during pregnancy and listeriosis, as supported by their lack of knowledge in some areas. If that lack is remedied, the knowledge gained could improve counselling practices.

Congenital cytomegalovirus infection

Each year, thousands of children are born with or develop permanent disabilities such as hearing loss, vision loss, motor and cognitive deficits from congenital CMV infection (cCMV). However, awareness of cCMV and its associated sequelae is very low in pregnant women and healthcare providers. Both targeted and universal approaches to screen newborns for CMV infection are now achievable due to recent scientific advances including the development of a rapid, high-throughput method for detecting CMV in saliva, the efficacy of antiviral treatment in symptomatic infants, and the demonstration of cost effectiveness of CMV screening. Future studies are needed to address gaps in our understanding on the role of non-primary maternal CMV infections, the evaluation of antiviral treatment in asymptomatic infants, and the implementation of prevention strategies for cCMV.

Congenital Toxoplasmosis: A Plea for a Neglected Disease

Maternal infection by Toxoplasma gondii during pregnancy may have serious consequences for the fetus, ranging from miscarriage, central nervous system involvement, retinochoroiditis, or subclinical infection at birth with a risk of late onset of ocular diseases. As infection in pregnant women is usually symptomless, the diagnosis relies only on serological tests. Some countries like France and Austria have organized a regular serological testing of pregnant women, some others have no prenatal program of surveillance. Reasons for these discrepant attitudes are many and debatable. Among them are the efficacy of antenatal treatment and cost-effectiveness of such a program. A significant body of data demonstrated that rapid onset of treatment after maternal infection reduces the risk and severity of fetal infection. Recent cost-effectiveness studies support regular screening. This lack of consensus put both pregnant women and care providers in a difficult situation. Another reason why congenital toxoplasmosis is disregarded in some countries is the lack of precise information about its impact on the population. Precise estimations on the burden of the disease can be achieved by systematic screening that will avoid bias or underreporting of cases and provide a clear view of its outcome.

Effectiveness of message framing on women's intention to perform cytomegalovirus prevention behaviors: a cross-sectional study

Background

The purpose of this study was to evaluate the effect of message framing on women’s intention to perform cytomegalovirus (CMV) prevention behaviors involving handwashing, not sharing food and eating utensils, not kissing a child on the lips and not placing a pacifier in the mouth after it was in a child’s mouth.

Methods

An online panel of women 18–40 years, who were pregnant or planning a pregnancy were randomized in a 2 × 2 factorial design to receive 1 of 4 CMV fact sheets. The fact sheets were framed as either what could be gained or be lost by following (or not) the recommendations and the likelihood of being affected by CMV (i.e., small chance or one of the most common infections in infants). The questionnaire measured CMV knowledge, participation in CMV risk or prevention behaviors, perceived severity of and susceptibly to CMV, and the perceived control over and the efficacy of recommended prevention behaviors. The dependent variable, intention to modify behavior, was an index score that ranged from 0 to 16 with higher values indicating greater intention. Linear regression was used to evaluate the association between all independent variables and overall behavioral intention.

Results

The sample included 840 women; 15.5% were familiar with CMV. Behavioral intention was high (M = 10.43; SD = 5.13) but did not differ across the message frames (p = 0.23). Overall, behavioral intention was predicted by CMV knowledge, message credibility, perceived severity of CMV, perceived behavioral control and response efficacy. Significant interactions with gain vs. loss frame were observed for perceived behavioral control (p = 0.03) and response efficacy (p = .003).

Conclusions

Framing CMV messages by what women stand to gain or lose interacts with perceived behavioral control and response efficacy to influence behavioral intention. Perceived behavioral control and response efficacy were most predictive of behavioral intention overall regardless of frame. Messaging that focuses on these two variables, particularly for avoiding kissing a child on the lips and sharing food, cups and utensils, may result in greater gains in intention to participate in CMV prevention behaviors.

Knowledge of congenital cytomegalovirus (cCMV) among physical and occupational therapists in the United States

Congenital cytomegalovirus (cCMV) infections cause more children to have permanent disabilities than Down Syndrome, Fetal Alcohol Syndrome, Spina Bifida, and pediatric HIV/AIDS combined. The risk of infection during pregnancy can be significantly decreased using universal precautions, such as thorough handwashing and cleansing of surfaces and objects that have come into contact with infected body fluids. Children under 3 years of age are commonly asymptomatic excretors of CMV, with the highest viral loads present in saliva. Pediatric therapists have regular close contact with young children, and are thus likely at elevated occupational risk of acquiring CMV. Our objective was to evaluate therapist knowledge of cCMV and its transmission. We recruited American Occupational Therapy Association (AOTA) and American Physical Therapy Association (APTA) members via electronic newsletters and printed flyers from April to September 2015. Participants completed an online, anonymous 24-question survey using Survey Monkey. We compared responses between groups and previously published CMV awareness data using binomial tests of difference of proportions and multiple logistic regression. Our study identified both a low level of therapist awareness and poor demonstrated understanding of cCMV. Self-reported cCMV awareness amongst therapists was greater than awareness in the general population, and equivalent to awareness amongst health care professionals. Whereas 52% of participants self-reported awareness of cCMV, only 18% demonstrated understanding of the behavioral modes of CMV transmission. Fewer therapists reported awareness of cCMV than other, less prevalent conditions. Higher levels of health risk knowledge were associated with greater contact with children. Most participants reported learning about cCMV from the workplace. The knowledge gaps between self-reported awareness of cCMV and demonstrated understanding of modes of transmission described by our results emphasize the need for additional training of therapists. cCMV is preventable, and accurate knowledge of modes of transmission is crucial for the health of practitioners and clients.

Congenital cytomegalovirus infection in pregnancy and the neonate: consensus recommendations for prevention, diagnosis, and therapy

Congenital cytomegalovirus is the most frequent, yet under-recognised, infectious cause of newborn malformation in developed countries. Despite its clinical and public health importance, questions remain regarding the best diagnostic methods for identifying maternal and neonatal infection, and regarding optimal prevention and therapeutic strategies for infected mothers and neonates. The absence of guidelines impairs global efforts to decrease the effect of congenital cytomegalovirus. Data in the literature suggest that congenital cytomegalovirus infection remains a research priority, but data are yet to be translated into clinical practice. An informal International Congenital Cytomegalovirus Recommendations Group was convened in 2015 to address these questions and to provide recommendations for prevention, diagnosis, and treatment. On the basis of consensus discussions and a review of the literature, we do not support universal screening of mothers and the routine use of cytomegalovirus immunoglobulin for prophylaxis or treatment of infected mothers. However, treatment guidelines for infected neonates were recommended. Consideration must be given to universal neonatal screening for cytomegalovirus to facilitate early detection and intervention for sensorineural hearing loss and developmental delay, where appropriate. The group agreed that education and prevention strategies for mothers were beneficial, and that recommendations will need continual updating as further data become available.

Women's attitudes toward practicing cytomegalovirus prevention behaviors

Congenital cytomegalovirus (CMV) infection causes severe disabilities and developmental delays. Women's awareness of CMV is low. Only about half of healthcare providers report counseling women about behaviors to reduce CMV risk and public health education is limited. Routine CMV counseling is not recommend. Providers may lack time to counsel women; other conditions may take priority for counseling; there may be a perception that women are reluctant to follow advice. This cross-sectional descriptive study examined women's attitudes toward CMV prevention behaviors. Data were collected from an online panel of 840 U.S. women 18–40 years of age, who had a child < 5 years of age, and were pregnant or planning a pregnancy in the next 12 months. Questions assessed CMV awareness, frequency of past behaviors that transmit CMV, and attitudes toward eight CMV prevention behaviors. Only 15.5% of women were somewhat or very familiar with CMV. Very few women (6.1%) reported hearing from their provider about CMV. Women held positive attitudes toward the CMV prevention behaviors and perceived them as feasible. Least positive attitudes were toward not kissing a child on the lips and not sharing foods. Predictors of positive attitudes were CMV awareness, past behavior, talking to a healthcare provider, and perceived risk reduction. Healthcare providers and public health practitioners should collaborate to increase CMV awareness. Encouraging behaviors to reduce saliva sharing may result in greater gains in reducing CMV infection.

•

Overall, women hold favorable attitudes toward CMV prevention behaviors.

•

Women hold less favorable attitudes toward not kissing a child on the lips.

•

Women also hold less favorable attitudes toward not sharing food with a child.

•

Positive attitudes predicted by belief that their risk of infection would be reduced.

•

Providers and public health practitioners need to work together to increase awareness.

What people know about congenital CMV: an analysis of a large heterogeneous population through a web-based survey

Background

Congenital CMV (cCMV) infection is a serious public health issue due to both its worldwide prevalence and the severe and permanent impairments it causes. However, awareness of this infection is low in the general population and among pregnant women, and it also seems to be generally disregarded by healthcare providers. The identification of factors behind this inadequate level of knowledge could provide a basis for future preventive measures. This study aimed at evaluating awareness of CMV and cCMV infection and its correlation with socio-demographic variables in a general population.

Methods

The survey was carried out by computer-assisted web interviewing (CAWI). A questionnaire was sent via e-mail to the 70,975 individuals who comprised the whole population (students, administrative staff, teaching staff) of Milan University, Italy in 2015.

Results

Out of the 10,190 respondents, 5,351 (52.5 %) had already heard of CMV but only 3,216 (31.8 %) knew that this virus could be implicated in congenital infection. Urine and breastfeeding were the least recognized transmission routes for CMV infection; less than half of respondents accurately identified the right symptoms and sequelae caused by cCMV infection. The correct hygienic measures against cCMV infection were identified in percentages ranging from 55.6 to 75 % depending on the measures proposed but about one in three of interviewees deemed those measures unnecessary in the event of a pregnant woman already being CMV seropositive. From the mean knowledge scores the most complete quality of awareness of CMV turned out to be linked to childbearing-age (25–40 year) and with not having children, even if results for non-parents showed less of them having heard of cCMV than parents.

Conclusion

Our results indicate a limited and confused awareness of cCMV infection in a large, fairly young and well-educated Italian population.

Awareness of cytomegalovirus and risk factors for susceptibility among pregnant women, in Montreal, Canada

BACKGROUND

Advances in diagnostic and therapeutic modalities for congenital cytomegalovirus (CMV) infection have generated a mounting interest in identifying mothers susceptible to CMV. The objectives of this study were to evaluate the prevalence and socio-demographic determinants of CMV susceptibility and CMV awareness, among pregnant women, in Montreal, Quebec.

METHODS

Between April and December 2012, women delivering at Centre Hospitalier Universitaire Sainte Justine were recruited for the study. Stored serum from the first trimester of pregnancy was tested for CMV IgG. Knowledge about CMV and socio-demographic characteristics were collected via standardized questionnaire.

RESULTS

Four hundred and ninety one women were enrolled in the study. Overall, 225 mothers (46%) were seronegative for CMV, and 85% (n = 415) were unaware of CMV or the associated risks in pregnancy. Significant risk factors for CMV seronegative status included Canadian vs. foreign born (aOR 6.88, 95% CI 4.33-10.94), and high vs. low family income (aOR 4.68, 95% CI 2.09-10.48). Maternal employment status was the only significant predictor of CMV unawareness, with unemployed mothers at the highest risk (aOR 85.6, 95% CI 17.3-421.3).

CONCLUSIONS

Nearly half of pregnant women studied were at risk of primary infection, and yet, the majority was unaware of potential risks associated with CMV. Canadian born mothers and those with a high socioeconomic status were more likely to be CMV seronegative. Increased education about CMV infection, through public health interventions and obstetrician/pediatric counseling, is needed for all pregnant women.

Awareness of Cytomegalovirus Infection among Pregnant Women in Geneva, Switzerland: A Cross-sectional Study

BACKGROUND

Cytomegalovirus (CMV) is the most frequent cause of congenital infection and commonly associated with sensorineural deficit. At present, there is neither prophylaxis nor treatment during pregnancy. The objective of this study was to evaluate the level of awareness regarding CMV infection and its consequences in women delivering at the University of Geneva Hospitals (Geneva, Switzerland).

METHODS

The study consisted of a validated questionnaire completed by women in the immediate postpartum period.

RESULTS

The questionnaire was completed by 59% (314/528) of delivering women. Only 39% (123/314) knew about CMV and 19.7% (62/314) had received information about preventive measures. Women were more aware about other congenital diseases, such as toxoplasmosis (87%); human immunodeficiency virus (99%); syphilis (85.5%); rubella (92.3%); and group B Streptococcus (63%). Factors associated with CMV awareness were Swiss nationality, high education level, employment in health care or with children, and being followed by an obstetrician. Regarding quality of information, few were aware of the main CMV complications (deafness, 25.2%; mental retardation, 34.5%). Among those informed about CMV, most (74.6%) knew about preventive measures. Among these, 82.5% thought that these were easily applicable.

CONCLUSIONS

Most women were unaware of CMV infection and its potential risks during pregnancy. It is crucial to improve CMV information given to pregnant women to prevent the risks for the fetus/newborn.

Client knowledge, attitudes and practices regarding zoonoses: a metropolitan experience

OBJECTIVE

To assess knowledge, attitudes and practices in relation to zoonoses among pet owners.

METHODS

Questionnaire completed by 81 clients attending a small animal practice in Sydney, Australia.

RESULTS

Most (64.5%) clients reported that they were not concerned about contracting a disease from their pet, but 7.9% and 3.9% of clients were a little or very concerned, respectively; 23.7% of clients stated that they had not considered the possibility. Although respondents indicated that they had heard of a number of zoonoses, knowledge of animal sources and exposure pathways was generally low, particularly for the more important zoonoses in Australia such as toxoplasmosis, psittacosis and Q fever. Only 37.0%, 12.3% and 11.1%, respectively, of clients had heard of these diseases. Most respondents (84.1%) indicated that they viewed veterinarians as having the primary responsibility for providing information about zoonoses, yet less than half (48.1%) recalled ever getting information from their veterinarian. Likewise, many respondents (48.1%) indicated that medical professionals played a role in providing information about zoonoses, yet less than one-quarter (23.5%) recalled ever getting information from their doctor.

CONCLUSION

The low level of knowledge among pet owners about sources and exposure pathways indicates a need to strengthen communication between veterinarians, doctors and their clients around the possible risks of zoonoses and appropriate prevention strategies.
