Disparities in healthcare access and utilization associated with demographic and socioeconomic status hinder advancement of health equity. Thus, we designed a novel equity-focused approach to quantify variations of healthcare access/utilization from the expectation in national target populations. We additionally applied survey-weighted logistic regression models, to identify factors associated with usage of a particular type of health care. To facilitate generation of analysis datasets, we built an National Health and Nutrition Examination Survey (NHANES) knowledge graph to help automate source-level dynamic analyses across different survey years and subjects' characteristics...

BACKGROUND: To meet global cervical cancer elimination efforts, a wider range of affordable and accessible vaccines against human papillomavirus (HPV) are needed. We aimed to evaluate the immunogenicity and safety of a quadrivalent HPV vaccine (targeting HPV types 6, 11, 16, and 18), developed and manufactured by the Serum Institute of India (SIIPL). Here we report outcomes in the 9-14 years cohort. METHODS: This randomised, active-controlled, phase 2/3 trial was conducted at 12 tertiary care hospitals across India...

cSCC (cutaneous squamous cell carcinoma) and its precursors are a major cause of morbidity, especially in immunosuppressed patients, and are frequently associated with human papillomavirus (HPV) infections. The purpose of this study is to investigate the therapeutic potential of alpha-HPV vaccination for immunosuppressed patients with established cSCC and its precursors. In this retrospective study, all patients who received Gardasil-9® , a nonavalent HPV vaccine, as secondary prophylaxis were examined...

OBJECTIVE: A review of current knowledge on the efficacy of human papillomavirus (HPV) vaccination in preventing recurrent severe cervical lesions after excisional surgical treatment. METHODS AND RESULTS: HPV infection is necessary for the development of most cervical precancerous lesions and cervical cancers. Currently, three prophylactic vaccines against HPV infection are available on the market: bivalent Cervarix, quadrivalent Gardasil (formerly Silgard) and nonavalent Gardasil9...

Human papillomavirus (HPV) infection is the main cause of cervical cancer. HPV vaccination is considered an effective way to prevent cervical cancer. Although the vast majority of people experience no obvious adverse reactions after being vaccinated with HPV vaccine, the continuous monitoring of adverse events following immunization is important. Herein, we report the case of a previously healthy young woman who developed unilateral extraocular muscle palsy after receiving the third dose of the Gardasil HPV 9-valent vaccine (9vHPV) and was diagnosed with myasthenia gravis (MG)...

Background Routine immunization of both girls and boys starting from nine years of age with the human papillomavirus (HPV) vaccine is the current recommendation. The objective of this retrospective study using National Health and Nutrition Examination Survey data was to evaluate the influence of sociodemographic factors on the series initiation and completion of the HPV vaccine from 2011 to 2020. Methodology The chi-square test was used to examine the statistical significance of the association between categorical variables and receipt of the HPV vaccine...

Treatment of anogenital warts (AGWs) is challenging. Candida antigen immunotherapy has been proven to be a safe and relatively effective therapeutic modality; nevertheless, some patients may experience a partial or no response. Combining Candida antigen with other immunotherapies has been proposed to improve the cure rate. Immunotherapy with human papillomavirus (HPV) vaccines has been tried with conflicting outcomes. This study aimed to  assess the efficacy and safety of intralesional Candida antigen, either alone or in combination with intralesional bivalent or quadrivalent HPV vaccines, for treating multiple AGWs...

BACKGROUND: An Escherichia coli-produced human papillomavirus (HPV) 16 and 18 bivalent vaccine (Cecolin) was prequalified by WHO in 2021. This study aimed to compare the immunogenicity of the E coli-produced HPV 9-valent vaccine Cecolin 9 (against HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58) with Gardasil 9. METHODS: This was a randomised, single-blind trial conducted in China. Healthy non-pregnant women aged 18-26 years, who were not breastfeeding and with no HPV vaccination history, were enrolled in the Ganyu Centre for Disease Control and Prevention (Lianyungang City, Jiangsu Province, China)...

INTRODUCTION: Cervical cancer related to high risk-human papillomavirus (HR-HPV) is the second female cancer in the Republic of Congo (Congo). We herein evaluated the molecular epidemiology of cervical HPV infection and associated risk factors in Congolese women living in urban (Brazzaville) and rural (Plateaux department) settings. PATIENTS AND METHODS: A population-based, cross-sectional survey was conducted to collect demographic and behavioral data among Congolese women, and to obtain endocervical swab samples for HPV DNA molecular detection (Anyplex II HPV28, Seegene, Seoul, South Korea)...

OBJECTIVE: To assess the quality of information presented in YouTube videos about human papillomavirus vaccination. METHODS: The descriptive study was conducted at Konya Meram Education and Research Hospital, On October 15, 2019 when the YouTube website was search using the terms 'human papillomavirus', 'HPV vaccine' and 'Gardasil'. The vide-os were recorded to a playlist by two individual gynaecologists to prevent any change in the listed videos. The videos were categorised into 3 groups; useful in-formation group A, misleading information group B and insufficient information group C...

Mozambique has one of the highest rates of cervical cancer in the world. Human papillomavirus (HPV) vaccination was introduced in 2021. This study evaluated the health and economic impact of the current HPV vaccine (GARDASIL® hereafter referred to as GARDASIL-4) and two other vaccines (CECOLIN® and CERVARIX® ) that could be used in the future. A static cohort model was used to estimate the costs and benefits of vaccinating girls in Mozambique over the period 2022-2031. The primary outcome measure was the incremental cost per disability-adjusted life-year averted from a government perspective...

Cervical cancer is the most common health problem among global young women. Cervical intraepithelial neoplasia (CIN) is a pre-invasive stage of cervical cancer, the major cause of which is human papillomavirus (HPV), and vaccination has a promising effect on reducing the progression of CIN lesions. The current study was a retrospective case control investigation in two centers, Shiraz and Sari Universities of Medical Sciences from 2018 to 2020 to evaluate the effect of quadrivalent HPV vaccination on CIN lesions (I, II, and III)...

BACKGROUND: Sub-Saharan Africa has the highest rate of cervical cancer cases and deaths worldwide. Kenya introduced a quadrivalent HPV vaccine (GARDASIL, hereafter referred to as GARDASIL-4) for ten-year-old girls in late 2019 with donor support from Gavi, the Vaccine Alliance. As Kenya may soon graduate from Gavi support, it is important to evaluate the potential cost-effectiveness and budget impact of the current HPV vaccine, and potential alternatives. METHODS: We used a proportionate outcomes static cohort model to evaluate the annual budget impact and lifetime cost-effectiveness of vaccinating ten-year-old girls over the period 2020-2029...

PURPOSE: Australia has a school-based human papillomavirus (HPV) vaccination scheme that was implemented for girls in 2007 and for boys in 2013. HPV vaccination status is important for many studies into HPV infection. Here we wanted to estimate the validity of self-reported HPV vaccination status by comparing self-report to data from the national vaccination register. METHODS: Australian residents aged 18-70 years were recruited for the Oral Diversity Study from October 2020 to November 2021...

Human papillomavirus (HPV) vaccines based on HPV L1 virus-like particles (VLPs) are already licensed but not accessible worldwide. About 38.0 million people were living with HIV in 2020 and there is no HIV vaccine yet. Therefore, safe, effective, and affordable vaccines against both viruses are an urgent need. In this study, the HIV-1 P18I10 CTL peptide from the V3 loop of HIV-1 gp120 glycoprotein was inserted into the HPV16 L1 protein to construct chimeric HPV:HIV (L1:P18I10) VLPs. Instead of the traditional baculovirus expression vector/insect cell (BEVS/IC) system, we established an alternative mammalian 293F cell-based expression system using cost-effective polyethylenimine-mediated transfection for L1:P18I10 protein production...

High-risk human papillomavirus (hrHPV) infection is the cause of most cervical cancers. Since therapeutic vaccines are not yet available for clinical practice, the administration of HPV prophylactic vaccines in patients with cervical intraepithelial neoplasia (CIN) arouses great interest and its value after excisional treatment of CIN remains unclear. We conducted this prospective cohort study to evaluate the impact of HPV prophylactic vaccination on preventing women from subsequent infection and cervical lesions after excision treatment...

BACKGROUND: Human papillomavirus (HPV) infection is associated with anal cancers and is more prevalent in gay, bisexual, and men who have sex with men (gbMSM), partly due to their vulnerability to HIV infection. Baseline HPV genotype distributions and risk factors can inform the design of next-generation HPV vaccines to prevent anal cancer. METHODS: A cross-sectional study was conducted among gbMSM receiving care at a HIV/STI clinic in Nairobi, Kenya. Anal swabs were genotyped using a Luminex microsphere array...

Gardasil® (Merck) and Cervarix® (GlaxoSmithKline) both provide protection against infection with Human Papillomavirus 16 (HPV16) and Human Papillomavirus 18 (HPV18), that account for around 70% of cervical cancers. Both vaccines have been shown to induce high levels of neutralizing antibodies and are known to protect against progression beyond cervical intraepithelial neoplasia grade 2 (CIN2+), although Cervarix® has been linked to enhanced protection from progression. However, beyond the transmission-blocking activity of neutralizing antibodies against HPV, no clear correlate of protection has been defined that may explain persistent control and clearance elicited by HPV vaccines...

UNLABELLED: Post-marketing pharmacosurveillance is important to reduce harm to patients from marketed drugs. Oral adverse drug reactions (OADRs) are seldom reported and only few OADRs are listed scarcely in summary of product characteristics (SmPC) of drugs. OBJECTIVE: Structured search for OADRs in the Danish Medicines Agencies database from January 2009 to July 2019. RESULTS: Forty-eight % of OADRs were categorized as "serious" where Oro-facial swelling was reported 1041 times, medication-related osteonecrosis of the jaw (MRONJ) 607 times and para- and hypoaesthesia 329 times...
