Filter by:We are evaluating whether 15-26 year old males and females need a 3rd dose of the human papillomavirus (HPV) vaccine, or whether 2 doses provide similar protection as 3 doses from the 9 types of HPV that it protects against.
In sinonasal inverted papilloma (SNIP) it is very challenging to discriminate between tumor and surrounding tissue. Local recurrence is a frequent phenomenon as it occurs in 16.5% of the cases. There is need for an instrument that is able to guide the surgeon in removing all tumor tissue, whereas resection of healthy tissue is minimalized. Molecular fluorescence guided surgery enables the visualization of targeted tumor-specific biomarkers by using fluorescence, thereby enhancing the contrast between normal mucosa and tumor tissue. The objective of this feasibility study is to determine if the intravenously administered conjugate bevacizumab-IRDye800CW accumulates more in SNIP than in normal sinonasal epithelium.
Non-classified atypical squamous cells (ASCUS) is the most common abnormal cervical cytology (%39). The risk of cervical intraepithelial neoplasia 2-3 is 5% and the risk of carcinoma is around 0.1% after diagnosis. Mostly human papillomavirus (HPV) is responsible for this transition. Most of them are transient, but some infections become persistent and can progress into precancer and invasive cancer. In the process of progression to cancer; patients with cell cycle problems are thought to be at risk. In some studies, B12 and folate deficiency, which play a role in DNA synthesis and repair, have been shown to induce incorrect binding of uracil to DNA, leading to DNA breakage and repair disorder. Therefore, in this study, it has been aimed that the relation of presence of atypical squamous cells and HPV persistence with folate and vitamin B12 levels which effect on immune system.
The only malignancy screening test among gynecological cancers is cervical cancer. Cytology examination and Hpv typing with smear are used as screening tests. Hpv positivity is detected in more than 90% of cervical cancers. However, only the Hpv 16-18 type positive patients undergo colposcopy in the routine screening program. Patients with Smear negative, Type 16-18 high-risk Hpv positivity are evaluated by quota after 1 year. the authors performed colposcopy with this study; authors aimed to compare the results of patients with type 16-18 Hpv positivity and type 16-18 high-risk Hpv positivity and to find out whether there was any difference between them. In this way, other high-risk Hpv types other than type 16-18 (31,33,35,45,51, etc.) may be exposed to premalign cervical lesions and possible cancer in a number of earlier and earlier periods by performing colposcopic examination instead of expecting to perform quota after 1 year. we aimed to remove.
This randomized controlled trial compares vacuum-assisted percutaneous excision to open standard surgical excision in women who have high-risk or borderline, non-malignant breast lesions with respect to efficacy, safety, cosmesis and patient satisfaction.
This is a randomized, double-blind, active-controlled, phaseI/II clinical trial to enroll 200 healthy female including 80 healthy adult aged 19 to 26 years and 120 adolescents aged 9 to 13 years to assess the safety and immunogenicity of NBP615 in comparison with Gardasil. In order to confirm the safety, 80 healthy adult should be enrolled first, and the safety of the test product (NBP615) will be confirmed by 2nd vaccination in adults. After that, enrolled of 120 adolescents proceeds. participants who previously agreed to participate in the study will be screened and only those participants who met the inclusion/exclusion criteria will be randomized in to 1:1 to receive test product (NBP615) or reference product (Gardasil pre-filled syringe). Three/ Two doses of 0.5 ml IM injection will be given and two blood sample, pre vaccine and post vaccine 4 weeks after completion of vaccine will be collected to assess the immunogenicity of NBP615 and Gardasil, comparator HPV vaccine. Solicited adverse events occurring up to 7 days after each dose of the investigational product will be collected in the diary card. Unsolicited adverse events occurring up to 28 days after each dose of the investigational product will be collated in the diary card. Serious adverse events will be collected during the entire study period. In addition to this safety data will be collected through the study period by active contact with the study participants by doing home visit or by telephone contact.
Human Papilloma Virus (HPV) is one of the most common causes of sexually transmitted diseases and its link with malignancies is well established, especially with anogenital tract cancers (cervical, vaginal, vulvar, anal cancers). HPV 16 and 18 are the most commonly isolated HPV types in cervical cancer, however not all infections with HPV 16 or 18 progress to cancer. After the HPV test has been used in cervical cancer screening, there have been concerns about whether women carry this virus. Although HPV testing may cause negative emotional responses, adverse emotional responses are related to HPV infection rather than testing. In this respect, there were several studies which evaluated the quality of life and psychological responses of women with positive HPV test results and it is known that positive HPV test results cause additional anxiety, distress and negative emotional responses in women. We hypothesized that the awareness of having a sexually transmitted infection in women with HPV and, therefore, a close follow-up and the need for further investigation such as colposcopy can affect their sexual life. In this study, we aimed to observe the changes in sexual function and anxiety of the HPV positive women with validated objective tools after being informed about their co-test results.
Human Papillomavirus (HPV) is a significant public health issue affecting nearly 14 million people in the United States. HPV can lead to cervical, oropharyngeal, anal, and penile cancers as well as genital warts.The purpose of this study is to test the comparative effectiveness of two interventions, AFIX only vs. AFIX + communication training, to increase Human Papillomavirus (HPV) vaccination rates among adolescent patients in outpatient clinic settings. Providers and staff at four pediatric practices will be randomized to receive an in-person AFIX consultation or an AFIX consultation combined with communication training and commitment poster displays. Provider and parent data will be collected via a tablet computer RedCap survey. Additional practice and provider level HPV vaccination rates will be collected via patient de-identified claims data. The results of this study could contribute to the existing body of literature that suggests provider recommendations and routine vaccination assessments are key to increasing HPV vaccination uptake. This project has the potential to lead to the implementation and dissemination of low resource interventions to increase HPV vaccination rates among children and adolescents.
Cervical cancer is the most common cause of cancer and a leading cause of death among HIV-infected women living in resource-limited settings. Although screening for premalignant lesions is an effective way of reducing cervical cancer incidence, its uptake in low-resource settings to date is low. The use of HPV testing for primary screening is currently recommended by many guidelines - including the WHO guidelines for cervical cancer screening in resource-limited settings - because of its greater sensitivity and ease of use compared to other options. However, these WHO guidelines have both highlighted the need to conduct more research on appropriate HPV-based algorithms among HIV-infected women, as immunodeficiency may affect the screening performance. Indeed, HPV infections in HIV-infected women are very common, so there is a need for additional triage to identify women most at risk and there remains considerable uncertainty on the optimal option for such triage. Most of the evidence available comes from HIV-negative populations living in high-resource settings and is not necessarily relevant for low-resource contexts where the epidemiological background is different, women access late to screening and may not have follow up visits, where financial constraints are important and health service resources limited. Hence, the proposed project aims to provide evidence on the effectiveness and feasibility of HPV-based screening algorithms among HIV-infected women in low-resource settings. This multicenter cross-sectional study will include 3,000 HIV-infected women (30-49 years old) receiving HAART and followed in Abidjan (Ivory Coast), Bobo-Dioulasso (Burkina Faso) and Phnom Penh (Cambodia). After self-collection of cervico-vaginal samples, each participant will have an HPV test with partial genotyping primary using the Xpert HPV assay, a real-time PCR assay that provides the possibility of identifying 14 HR-HPV types within one hour. The Xpert HPV test has been chosen because of the wide availability of the Genexpert platform in HIV care centers from resource-limited settings. Furthermore, it can specifically detect HPV-16, 18 and 45, the most carcinogenic HPV types in both HIV-negative and HIV-positive women, separately from other high-risk HPV types. VIA will be another triage option either alone or combined to HPV DNA genotyping. In addition, participants treated for cervical lesion will be followed over 12 months to assess the risk of post-treatment lesions (CIN2+/HSIL) and to identify associated risk-factors.
Background: Prevention of cervical cancer and genital warts could be achieved by immunization with the prophylactic human papillomavirus (HPV) vaccines commercially available. However, in the U.S. only 38% of females and 14% of males in the recommended age group (9-26 years) receive the complete, three-dose HPV vaccine. Because the HPV vaccine is covered under the Vaccine for Children Program, the underinsured and uninsured have no-cost access. Nonetheless, data from Los Angeles county suggest that HPV vaccination rates among the uninsured and underinsured groups are significantly lower than the national average, likely related to knowledge of the vaccine, transportation, number of doses and concern of side effects. Aim: To evaluate the efficacy of health oriented text messaging to increase HPV vaccine uptake versus standard health messaging (Center for Disease Control and Prevention (CDC) HPV vaccine information flyers). Hypothesis: The investigators hypothesize that receiving general health messaging, including messages regarding the benefits of the HPV vaccine, will increase HPV vaccine uptake. Text messaging will also be more successful in reaching the uninsured and underinsured populations than will traditional flyers/information pamphlets used in clinics. Methods: A cluster randomized trial design will be used to recruit participants from four clinics in Los Angeles County which offer pediatric vaccination to uninsured and underinsured children. The sample will include women aged 18-45 years of age. Two of the sites will be randomized to the text messaging arm and the other clinic will be randomized to the control arm (standard messaging: CDC flyers and pamphlets available for patients at the clinic). Outcome measures will be HPV vaccinations rates at those clinics. Rates will be defined into groups who received 1 dose, 2 doses and 3 doses. Anticipated Results: The investigators expect to find statistically significant higher HPV vaccination rates among children and women in the text messaging study arm compared to the control arm. Implications and Future Studies: This pilot study will give us preliminary data to submit a larger randomized controlled trial to examine the efficacy of text messaging.
