RESUMEN

BACKGROUND: The aim of this study is to examine cervical cancer screening (CCS) uptake among women living with hypertension and HIV in Tanzania. METHODS: We used the recently released 2022 Tanzania Demographic and Health Survey. The outcome variable assessed in the study was CCS, whereas chronic morbidities constituted the main explanatory variable. Data analysis was based on observations from 6,298 women aged 30-49 years. Multivariable logistic regression models were used to determine the association between hypertension and HIV status, and CCS uptake. The analyses were computed in STATA 18. RESULTS: Out of the 6,298 respondents, only 805 (12.8%) had undergone CCS with higher screening uptake among those living with either one of the disease (28.5%) than among those living with neither hypertension or HIV. The highest proportion was found among those who had ever been diagnosed with hypertension (24.1%) and among women with positive HIV test results (36.7%). There was a significantly higher likelihood of undergoing screening for cervical cancer among women living with at least one of the diseases [AOR = 2.4; 95% CI: 1.4-2.8], compared to those without these conditions. Women diagnosed with hypertension showed increased likelihood of undergoing CCS [AOR = 1.4; 95%CI: 1.1-1.7]. Similarly, women with a positive HIV test result demonstrated higher odds of screening uptake [AOR = 5.2; 95%CI: 4.0-6.7]. CONCLUSION: The study found a positive association between comorbidities and CCS uptake in Tanzanian women. Our findings emphasize the critical importance of ensuring accessibility and adherence to essential screenings for individuals with chronic morbid conditions. Future efforts should focus on strengthening existing integrated services and identifying potential barriers to accessing CCS within these healthcare settings to optimize cervical cancer prevention efforts for individuals with chronic morbidities.

RESUMEN

BACKGROUND: Immunosuppressive status is prevalent in cancer patients and increases the complexity of tumor immunotherapy. It has been found that Listeria-vectored tumor vaccines had the potential ability of two-side regulatory effect on the immune response during immunotherapy. RESULTS: The results show that the combined immunotherapy with the LM∆E6E7 and LI∆E6E7, the two cervical cancer vaccine candidate strains constructed by our lab, improves the antitumor immune response and inhibits the suppressive immune response in tumor-bearing mice in vivo, confirming the two-sided regulatory ability of the immune response caused by Listeria-vectored tumor vaccines. The immunotherapy reduces the expression level of myeloid-derived suppressor cells (MDSCs)-inducing factors and then inhibits the phosphorylation level of STAT3 protein, the regulatory factor of MDSCs differentiation, to reduce the MDSCs formation ability. Moreover, vaccines reduce the expression of functional molecules associated with MDSCs may by inhibiting the phosphorylation level of the JAK1-STAT1 and JAK2-STAT3 pathways in tumor tissues to attenuate the immunosuppressive function of MDSCs. CONCLUSIONS: Immunotherapy with Listeria-vectored cervical cancer vaccines significantly reduces the level and function of MDSCs in vivo, which is the key point to the destruction of immunosuppression. The study for the first to elucidate the mechanism of breaking the immunosuppression.

RESUMEN

OBJECTIVES: Participants' comprehension of research process affects the quality of research output, which is the reason why translation of research instruments into local languages is standard practice. Literature has consistently reported that in Africa, knowledge about cervical cancer is low but paradoxically, expressed, and actual uptake of human papillomavirus vaccine for its prevention is high. This study explored the Yoruba names of cervical cancer among Yoruba people in Ibadan, Nigeria to guide the translation of cervical cancer research instruments to Yoruba language. DESIGN: Exploratory case study design was used and data were obtained with 10 in-depth interviews and four focused group discussions. Data were analysed using content analysis. SETTINGS: The study took place in Ibadan North local government area, Southwest Nigeria. PARTICIPANTS: These were 4 traditional healers, 3 Yoruba linguists, 3 public health educators and 38 parents of adolescents. MEASURES: These were Yoruba names for cervical cancer and their meanings. RESULTS: Participants were aware of cervical cancer but only the traditional healers and public health educators had names for it. These names were highly varied. The public health educators gave names that were linked with different parts of the female reproductive system and external genital which were actually different medical conditions. Each traditional healer also had different names for cervical cancer, which either described the female body parts, or symptoms of female genital infections. These various names can lead to unnecessary misconceptions and misinformation about cervical cancer, its prevention, management, and research. CONCLUSIONS: There was no consensus Yoruba name for cervical cancer among the study participants. Efforts to educate the Yoruba speaking populace about cervical cancer, its prevention, management and participation in its research can be frustrated if a generally accepted Yoruba name is not provided for this cancer. Stakeholders' collaboration is required to get an appropriate Yoruba name for cervical cancer.

RESUMEN

OBJECTIVE: To evaluate the willingness of healthcare providers to perform population-based screening in primary healthcare institutions in China. METHODS: Healthcare providers of 262 primary healthcare institutions in Tianjin were invited to fill out a questionnaire consisting of demographic characteristics, workload, and knowledge of, attitude towards and willingness to perform breast, cervical and colorectal cancer screening. Willingness to screen was the primary outcome. Multilevel logistic regression models were conducted to analyse the determinants of healthcare providers' willingness to screen. ORs and 95% CIs were estimated. RESULTS: A total of 554 healthcare providers from 244 institutions answered the questionnaire. 67.2%, 72.1% and 74.3% were willing to perform breast, cervical and colorectal cancer screening, respectively. A negative attitude towards screening was associated with a low willingness for cervical (OR=0.27; 95% CI 0.08, 0.94) and colorectal (OR=0.08; 95% CI 0.02, 0.30) cancer screening, while this was not statistically significant for breast cancer screening (OR=0.30; 95% CI 0.08, 1.12). For breast, cervical and colorectal cancer screening, 70.1%, 63.8% and 59.0% of healthcare providers reported a shortage of staff dedicated to screening. A perceived reasonable manpower allocation was a determinant of increased willingness to perform breast (OR=2.86; 95% CI 1.03, 7.88) and colorectal (OR=2.70; 95% CI 1.22, 5.99) cancer screening. However, this was not significant for cervical cancer screening (OR=1.76; 95% CI 0.74, 4.18). CONCLUSIONS: In China, healthcare providers with a positive attitude towards screening have a stronger willingness to contribute to cancer screening, and therefore healthcare providers' attitude, recognition of the importance of screening and acceptable workload should be optimised to improve the uptake of cancer screening.

RESUMEN

INTRODUCTION: Cervical cancer is the second dominant type of cancer among Ivorian women with an estimated age-standardised incidence and mortality rate of 31.2 cases and 22.8 deaths per 100,000 women in 2020, respectively. The Ivorian government through its Ministry of Health implemented the National Cancer Control Programme (NCCP) in 2003 with the aim of improving the prevention, early detection and treatment of cancers in Côte d'Ivoire. Yet, there is a low uptake of CCS (1.2%). Thus, making CCS uptake an important public health concern in the country. Understanding of the extent to which reproductive factors predict CCS uptake is limited in literature. This study aimed to investigate reproductive factors as a predictor of women's uptake of CCS in Côte d'Ivoire. METHODS: Data from the 2021 Côte d'Ivoire Demographic and Health Survey. A sample of 9,078 women aged 25-49 years were analyzed. The outcome variable was CCS uptake while other variables considered included age at menarche, history of STI, sexual debut, parity, age, educational level, wealth index, health insurance, place of residence, and media exposure. A multivariable logistic regression model was fitted to examine the association between the outcome of interest and predictors at 95% confidence interval. RESULTS: Approximately, 7.52% of women aged 25-49 years had ever undergone testing for cervical cancer by a healthcare provider. Early menarche was associated with lower odds of CCS uptake [AOR = 0.78; CI = 0.65-0.95]. Compared to those who had no STI, women with a history of STI were more likely to screen for cervical cancer [AOR = 2.63; CI = 2.02-3.42]. Increasing age, higher educational attainment, having health insurance, and being exposed to media were significantly associated with CCS uptake. CONCLUSION: In Cote d'Ivoire, age at menarche and STI history constitute reproductive factors that were significantly associated with women's uptake of CCS. It is imperative for public policy to focus on increasing CCS in these higher-risk women (i.e., women who experienced early menarche, women with early sexual debut and higher parity) through increased sensitization on cervical cancer risk factors.

RESUMEN

Current estimates of the HPV infection rate in China vary by geographic region (9.6-23.6%), with two age peaks in prevalence in women ≤20-25 years of age and 50-60 years of age. HPV-16, 52 and 58 are the most commonly-detected HPV genotypes in the Chinese population. In China, five HPV vaccines are licensed and several others are undergoing clinical trials. Multiple RCTs have shown the efficacy and safety of the bvHPV (Cervarix), Escherichia coli-produced bvHPV (Cecolin), Pichia pastoris-produced bvHPV (Walrinvax), qvHPV (Gardasil) and 9vHPV (Gardasil-9) vaccines in Chinese populations, including two studies showing long-term efficacy (≥8 years) for the bvHPV and qvHPV vaccines. Real-world data from China are scarce. Although modeling studies in China show HPV vaccination is cost-effective, uptake and population coverage are relatively low. Various policies have been implemented to raise awareness and increase vaccine coverage, with the long-term aim of eliminating cervical cancer in China.

RESUMEN

Cervical cancer is a significant public health concern in Ethiopia. It is mainly caused by persistent infection with the human papillomaviruses. The aim of this study was to assess the relationship between carcinogenic risk of probable, possible and low risk HPV infection and those of cervical intraepithelial neoplasia (CIN) and cervical cancer. A cross sectional study nested from prospective cohort study was conducted in Bahir Dar, northwest Ethiopia. Statistical analyses were performed using SPSSversion 26.0. HPV-16 was associated with a relatively higher risk of CIN II+, (AOR = 15.42; 95% CI 6.81-34.91). In addition, HPV-52, -18, -53 and -58, were significantly associated with an increased risk of CIN II+, (AOR = 7.38 (1.73-31.54), 5.42 (1.61-18.31), 4.08 (1.53-10.87), and 3.17 (1.00-10.03)), respectively. The current study shows high rate of HPV with predominance of HPV-16, -53, -58, -18, -35, and -52. The quadrivalent and nonavalent vaccine had only covered 27.1% and 45% of the circulating HPV genotypes. Ethiopia may need to consider introduction of nonavalent vaccine into the national public health strategy. Polyvalent vaccine which includes the genotypes not covered by existing approved vaccines should be considered.

RESUMEN

BACKGROUND: Knowledge of risk factors and symptoms of cervical cancer has been found to promote uptake of screening of cervical cancer. Most interventions targeted women without much involvement of men (husbands/decision makers) who are often decision makers in many low- and middle-income countries. This study aimed at assessing baseline knowledge and intended behavior of both women and men to enable design specific targeted messages to increase uptake of cervical cancer screening and promote early detection of women with symptoms. METHODS: This cross-sectional study was conducted in two districts in Western Uganda using the modified African Women Awareness of CANcer (AWACAN) questionnaire. Women aged 30-49 years and their husbands/decision makers were interviewed. Knowledge on risk factors and symptoms, intended behavior and barriers towards participation in cervical cancer screening and treatment were assessed. Descriptive and logistic regression analyses were done to establish the association between knowledge levels and other factors comparing women to men. RESULTS: A total of 724 women and 692 men were enrolled. Of these, 71.0% women and 67.2% men had ever heard of cervical cancer and 8.8% women had ever been screened. Knowledge of risk factors and symptoms of cervical cancer was high and similar for both women and men. Lack of decision making by women was associated with low knowledge of risk factors (X2 = 14.542; p = 0.01), low education (X2 = 36.05, p < 0.01) and older age (X2 = 17.33, p < 0.01). Men had better help seeking behavior than women (X2 = 64.96, p < 0.01, OR = 0.39, 95% CI: 0.31-0.50) and were more confident and skilled in recognising a sign or symptom of cervical cancer (X2 = 27.28, p < 0.01, OR = 0.52, CI (0.40-0.67). CONCLUSION: The baseline knowledge for cervical cancer was high in majority of participants and similar in both women and men. Their intended behavior towards screening was also positive but screening uptake was very low. This study suggests developing messages on multiple interventions to promote screening behavior in addition to education, consisting of male involvement, women empowerment and making services available, accessible and women friendly.

RESUMEN

BACKGROUND: Cervical cancer is one of the most common cancers in women worldwide and a cause of high mortality among people. Pap smear screening is an appropriate method to prevent cervical cancer and reduce its mortality. AIM: This study aimed to determine the effect of web-based education based on the Health Belief Model (HBM) on cervical cancer screening behavior in middle-aged women. METHODS AND RESULTS: This study is a quasi-experimental interventional research that was conducted on 240 middle-aged women aged 40-59 years in Isfahan, Iran, in 2022. An online educational intervention based on the constructs of the Health Belief Model was conducted for the intervention group using the Triple-B platform. The information on the intervention and control groups was collected before, immediately after the intervention, and 2 months later using a valid questionnaire. The gathered Data was analyzed using ANOVA and LSD post-hoc, independent samples t test, chi-square, and MANCOVA statistical tests in SPSS 26 software. After the intervention, the mean scores of knowledge, perceived susceptibility, perceived severity, perceived benefits, self-efficacy, and internal cues to action in the intervention group increased and the mean score of perceived barriers decreased (p < .001). The mean score of the external cues to action did not show a significant difference between the intervention and control groups before, immediately, and 2 months after the intervention. Two months after the intervention, 32 women (26.2%) in the intervention group and two women (1.7%) in the control group performed the Pap smear test. CONCLUSION: Web-based educational intervention based on HBM using different strategies such as question and answer, presentation of infographics, lectures, brainstorming, showing videos and numerous educational images can be an effective way for increasing knowledge and cognitive variables of women and doing Pap smear test.

RESUMEN

Introduction: Health literacy is crucial to adherence to medical interventions in therapeutics, prevention, and diagnosis. The basis for literacy is knowledge. To accomplish the goals for the elimination of cervical cancer, one of the most prevalent and preventable cancers, we must understand the determinants of non-adherence and address them specifically to ensure patients' active participation. Aim: To determine women's knowledge regarding the manifestations of cervical cancer and its prevention. Materials and methods: We conducted a cross-sectional study in an urban population from northern Portugal. Women aged 18 to 30 years were randomly assigned to answer the Cervical Cancer Awareness Measure questionnaire, including questions of knowledge about the causes and symptoms of cervical cancer, prospecting for individual and social-related determinants. Results: The total number of participants was 270, with a mean age of 24.7 years. Knowledge about symptoms scored 5.4 ± 2.6, with a maximum of 12 points, and knowledge about the causes scored 5.7 ± 1.9, with a maximum of 11 points. The correlation between both was 0.334. High education, high socio-economic status, self-perception of one's capacity to recognize symptoms, and knowledge about the HPV vaccine were associated with better knowledge. Discussion: Portuguese women present low knowledge about cervical cancer, potentially affecting their health through exposure to risk situations and non-adherence to routine screening.

RESUMEN

BACKGROUND: Preventive care is important for managing inflammatory bowel disease (IBD), yet primary care providers (PCPs) often face challenges in delivering such care due to discomfort and unfamiliarity with IBD-specific guidelines. This study aims to assess PCPs' attitudes towards, and practices in, providing preventive screenings for IBD patients, highlighting areas for improvement in guideline dissemination and education. METHODS: Using a web-based opt-in panel of PCPs (DocStyles survey, spring 2022), we assessed PCPs' comfort level with providing/recommending screenings and the reasons PCPs felt uncomfortable (n = 1,503). Being likely to provide/recommend screenings for depression/anxiety, skin cancer, osteoporosis, and cervical cancer were compared by PCPs' comfort level and frequency of seeing patients with IBD. We estimated adjusted odd ratios (AORs) of being likely to recommend screenings and selecting responses aligned with IBD-specific guidelines by use of clinical practice methods. RESULTS: About 72% of PCPs reported being comfortable recommending screenings to patients with IBD. The top reason identified for not feeling comfortable was unfamiliarity with IBD-specific screening guidelines (55%). Being comfortable was significantly associated with being likely to provide/recommend depression/anxiety (AOR = 3.99) and skin cancer screenings (AOR = 3.19) compared to being uncomfortable or unsure. Percentages of responses aligned with IBD-specific guidelines were lower than those aligned with general population guidelines for osteoporosis (21.7% vs. 27.8%) and cervical cancer screenings (34.9% vs. 43.9%), and responses aligned with IBD-specific guidelines did not differ by comfort level for both screenings. Timely review of guidelines specific to immunosuppressed patients was associated with being likely to provide/recommend screenings and selecting responses aligned with IBD-specific guidelines. CONCLUSIONS: Despite a general comfort among PCPs in recommending preventive screenings for IBD patients, gaps in knowledge regarding IBD-specific screening guidelines persist. Enhancing awareness and understanding of these guidelines through targeted education and resource provision may bridge this gap.

RESUMEN

The epidemiological and clinical aspects of Human Papillomavirus (HPV) infection in women have been extensively studied. However, there is a lack of information regarding HPV characteristics in males. In this study, we conducted a retrospective and observational study of 3737 consecutive male individuals attending outpatient clinics of Guangdong Women and Children Hospital from 2012 to 2023 in Guangzhou, South China, to determine the age- and genotype-specific prevalence of HPV in men. The results showed the overall prevalence of HPV among men was 42.15% (1575/3737), with variations ranging from 29.55% to 81.31% across distinct diagnostic populations. Low-risk HPV6 (15.47%), HPV11 (8.94%), and high-risk HPV52 (5.51%) were the most common types. The annual HPV prevalence decreased significantly (Z = -3.882, p < .001), ranging from 31.44% to 52.90%. 28.77% (1075/3737) of men manifested infection with a singular HPV type, predominantly identified as a low-risk type. The age-specific distribution of HPV infections revealed distinctive peaks in the < 25 y age group (47.60%, 208/437) and the 40-44 y age group (44.51%, 154/346). Notably, the positive rate of Chlamydia trachomatis was significantly higher among HPV-positive individuals in comparison to HPV-negatives (16.14% vs. 11.25%, p < .05). Our findings reveal a substantial prevalence of HPV infection among outpatient men in Guangzhou, South China. It is recommended to consider the inclusion of HPV vaccination for adolescent males in national immunization schedules, once an adequate supply of vaccines is accessible.

RESUMEN

BACKGROUND: Although HPV prophylactic vaccines can provide effective immune protection against high-risk HPV infection, studies have shown that the protective effect provided by them would decrease with the increased age of vaccination, and they are not recommended for those who are not in the appropriate age range for vaccination. Therefore, in those people who are not suitable for HPV prophylactic vaccines, it is worth considering establishing memory T-cell immunity to provide long-term immune surveillance and generate a rapid response against lesional cells to prevent tumorigenesis. METHODS: In this study, healthy mice were preimmunized with LM∆E6E7 and LI∆E6E7, the two Listeria-vectored cervical cancer vaccine candidate strains constructed previously by our laboratory, and then inoculated with tumor cells 40 d later. RESULTS: The results showed that preimmunization with LM∆E6E7 and LI∆E6E7 could establish protective memory T-cell immunity against tumor antigens in mice, which effectively eliminate tumor cells. 60% of mice preimmunized with vaccines did not develop tumors, and for the remaining mice, tumor growth was significantly inhibited. We found that preimmunization with vaccines may exert antitumor effects by promoting the enrichment of T cells at tumor site to exert specific immune responses, as well as inhibiting intratumoral angiogenesis and cell proliferation. CONCLUSION: Altogether, this study suggests that preimmunization with LM∆E6E7 and LI∆E6E7 can establish memory T-cell immunity against tumor antigens in vivo, which provides a viable plan for preventing tumorigenesis and inhibiting tumor progression.

RESUMEN

INTRODUCTION: Although cervical cancer screening is one of the most effective strategies to reduce the incidence and mortality of cervical cancer, the percentage of cervical cancer screening in low- and middle-income counties is low. In Kenya, the current nationwide prevalence and associated factors for the detection of cervical cancer is unknown. Therefore, this study aimed to assess the prevalence and associated factors for the detection of cervical cancer screening among women of reproductive age in Kenya using the Kenyan Demographic and Health Survey 2022. METHODS: This study used the most recent Kenyan Demographic and Health Survey data (2022) with a total weighted sample of 16,901 women. A mixed effects logistic regression analysis was performed and in the multivariable analysis, variables with a p-value below 0.05 were considered statistically significant. The strength of the association was evaluated using adjusted odds ratios along with their corresponding 95% confidence intervals. RESULTS: The prevalence of cervical cancer screening in Kenya was 16.81%(95% CI: 16.24, 17.38%). Having a history of abortion (AOR = 1.33, 95% CI: 1.171.50, 1.43), using modern contraceptive methods (AOR = 1.57, 95% CI: 1.25, 1.95), media exposure (AOR = 1.31, 95%CI: 1.03, 1.65), primary education (AOR = 1.56, 95%CI: 1.09, 2.22), secondary education (AOR = 21.99, 95% CI: 1.1.38, 2.87), higher education (AOR = 2..50, 95% CI: 1.71, 3.65), visiting health facility within the past 12 months (AOR = 1.61, 95%CI: 1.46, 1.79), positive HIV status (AOR: 3.50, 95% CI: 2.69, 4.57), being from a community with a higher proportion of educated individuals (AOR = 1.37, 95%CI: 1.13, 1.65) and being from a community with high proportion of poor individuals (AOR = 0.72, 9 5%CI: 0.60-0.87)) were significantly associated with cervical cancer screening. CONCLUSION: In Kenya, the prevalence of cervical cancer screening was found to be low. A history of abortion, use of modern contraceptives, exposure to the media, visits to health facilities in the past 12 months, HIV status, level of education, community educational level, and community wealth were identified as significant associated factors for cervical cancer screening. Therefore, it is recommended to implement targeted public health interventions that focus on these identified factors to improve the adoption of cervical cancer screening in Kenya.

RESUMEN

INTRODUCTION: Despite having a high risk of acquiring sexually transmitted infections, people who inject drugs (PWID) often do not receive recommended HPV screenings due to barriers to healthcare. Guideline-based cervical HPV screening and vaccination can prevent cervical cancer. Low-cost, low-barrier methods for cancer screening and prevention are important for vulnerable communities such as PWID. METHODS: We examined acceptability of HPV self-sampling at a syringe services program (SSP). Participants with a cervix (n = 49) participated in patient education followed by a survey to assess willingness to perform HPV self-sampling versus standard of care. RESULTS: 59% found self-sampling to be acceptable, citing privacy, ease, and quickness. Among those opting for HPV screening delivered by a provider (n = 16), participants cited concerns about adequate sampling (81%) and test accuracy (75%). Notably, only 18% of participants reported complete HPV vaccination. CONCLUSION: Cervical HPV self-sampling was acceptable to PWID. SSP-based efforts to provide preventative health services could place tools for cancer screening into the hands of PWID, a need-to-reach community.

RESUMEN

OBJECTIVE: To understand how breast and cervical cancer screening are influenced by communicating with a healthcare provider, patient activation, and social determinants of health. METHOD: Data were from the National Cancer Institute's Health Information National Trends Survey, focusing on women with no history of cancer at least 21 years old (N = 1466) to study cervical cancer screening and those at least 40 years old (N = 1114) to study breast cancer screening. Variables included patient-centered communication, electronic healthcare communication, patient activation, race/ethnicity, education, health insurance status, Appalachian residence, and financial insecurity. RESULTS: Electronic communication predicted both cancer screens, but especially for White women. Patient-centered communication influenced cervical cancer screening only for women with insurance. It only influenced mammography for those without insurance. Patient activation did not influence either cancer screen behavior. CONCLUSION: These data demonstrate more nuance is needed to parse potential effects of advocated-for healthcare behaviors. Use of publicly available datasets from can be informative but are limited methodologically. PRACTICE IMPLICATIONS: Healthcare providers and systems should promote use of patient portals and other electronic means of interaction outside regular clinical visits for all patients. However, attention needs to be paid to the unequal benefits they afford to patients.

RESUMEN

BACKGROUND: Cervical cancer eradication is one of the main goals for 2030 by the World Health Organization, which can only be achieved with high vaccination rates against Human Papilloma Virus. In Colombia, more and better scientific evidence is required to increase confidence in vaccination. The objective of this study is to evaluate the safety profile of the quadrivalent vaccine against HPV in the risk of developing autoimmune, neurological, and hematological diseases in adolescent women in Colombia. METHODS: We designed a cohort study based on national HPV vaccination records and incident diagnostic data for the diseases of special interest during 2012 and 2021. We included adolescent women between 9 and 19 years old and compared vaccinated and non-vaccinated cohorts using an Inverse Probability of Treatment Weighting (IPWT) method for each scenario disease and follow-up period (180 and 360 days). FINDINGS: The Odds Ratio (OR) of developing diseases of interest was estimated during two follow up periods, 180 and 360 days after the follow-up index date (Vaccination Day). The OR for developing rheumatoid arthritis was 4·4; CI95% (1·74 - 11·14), juvenile idiopathic arthritis was 2·76 IC95% (1·50 - 5·11), idiopathic thrombocytopenic purpura was 2·54 IC95% (1·28 - 5·02) and thyrotoxicosis was 2·86 IC95% (1·03 - 7·95), when comparing the vaccinated versus unvaccinated population. However, the temporal distribution of cases incident did not reveal a clear difference between the cohorts, since the rate of appearance of new cases has a constant linear behavior for the two groups. INTERPRETATION: For rheumatoid arthritis, juvenile idiopathic arthritis, idiopathic thrombocytopenic purpura, and thyrotoxicosis; the application of the vaccine had an effect on the development of the disease. Nevertheless, our results should be interpreted with caution and be further studied, considering that the biological plausibility of the events occurred without a clear temporal pattern in relation to the exposure to the vaccine.

RESUMEN

BACKGROUND: The human papillomavirus (HPV), a prevalent sexually transmitted infection, is linked to a wide range of diseases, with cervical cancer being the most common and serious one. HPV vaccination is crucial for preventing cervical cancer and other HPV-related problems. The low acceptability of HPV vaccination among teenagers globally is largely due to a lack of understanding and information about HPV among parents. Our study aimed to evaluate the level of knowledge, attitude, intention, and HPV vaccination among parents in Lebanon as well as the variables influencing Lebanese mothers' intentions to vaccinate their children. METHODS: A cross-sectional survey-based study involving 392 participants was conducted between May and June 2022. The study assessed parents' intention to vaccinate their children against HPV, their knowledge about HPV, and the HPV vaccine. The data was collected through an anonymous electronic questionnaire. A bivariate analysis was conducted using Student t-test and ANOVA to examine the relationship between the dependent variable "Intention to vaccination" and the secondary variables. The level of statistical significance was set at 0.05 for all data. RESULTS: Our findings showed that only 63% of the 392 participants claimed they would give their child the HPV vaccination. A positive significant association was demonstrated between "Intention to vaccinate against HPV" and mother's nationality, father's educational level, family income per month, information received about the HPV vaccine, parents' HPV vaccination, insurance coverage of the HPV vaccine, children's vaccinations with all required vaccines, knowledge of HPV, and knowledge of the HPV vaccine. Furthermore, when parents know about HPV, their desire to vaccinate their child increases by a factor of 1.832 times, and by 1.207 times when their knowledge level increases by one point. CONCLUSION: The majority of parents lacked a general understanding of most HPV-related statements, which highlights the requirement for educational interventions to raise parental awareness, understanding, and attitudes toward HPV and, as a result, increase parental acceptance of vaccinating their children. To increase the vaccination rate among adolescents, government authorities should ensure that the HPV vaccine is available in all hospitals and clinics and should be provided free of charge.

RESUMEN

Human Papilloma Virus (HPV) infection is a common, preventable, sexually transmitted disease with oncogenic potential and increasing incidence. This study aimed to gain an understanding of the knowledge and awareness of HPV, the HPV vaccine, and HPV-related cancers, and to evaluate the relationship between participant factors and HPV knowledge, vaccination uptake, and high-risk HPV (16/18) infection, among Indigenous Australians. Data from the 12-month follow-up of a longitudinal cohort study were utilized, involving 763 Indigenous Australian adults in South Australia. The data analysis found that the mean 7-item HPV knowledge tool (HPV-KT) score was 2.3 (95% CI: 2.1-2.4), HPV vaccination prevalence was 27.0% (95% CI: 23.6-30.5) and oral HPV 16/18 infection was 4.7% (95% CI: 3.2-6.2). Multivariable log-Poisson regression models showed ratios of approximately 1.5 times higher HPV-KT scores in females, previous recreational drug users, those who had self-rated as having excellent, very good or good general health and who had heard of HPV; and participants who were not HPV vaccinated had 0.8 times (MR = 0.8, 95% CI: 0.7-0.9) lower HPV-KT scores than their counterparts. The findings suggest that culturally safe education strategies are a necessary investment to improve vaccination coverage among Indigenous Australians and to reduce the impact of HPV and related cancers.
