Vaccination of COVID-19-convalescent individuals may generate 'hybrid' immunity of enhanced magnitude, durability, and cross-reactive breadth. Our primary goal was to characterize hybrid antibody (Ab) responses in a patient cohort infected with ancestral Wuhan-Hu-1 virus and vaccinated between 6 and 10 months later with the Wuhan-Hu-1-based BNT162b2 mRNA vaccine. We were particularly interested in determining the efficacy of neutralizing Ab responses against subsequently emergent SARS-CoV-2 variants.

Studies showed HPV carcinogenesis may be induced by oxidative stress affecting the host immune system. The objective of this study is to evaluate levels of four circulating oxidative stress biomarkers associated with the HPV infection, persistence, and cervical lesion status in women.

To enhance the durability of post-vaccination immunity and combat SARS-CoV-2 variants, boosters have been administered to two-dose vaccinees. However, long-term humoral responses following booster vaccination are not well characterized.

The 2022 outbreak of mpox in Louisiana was limited to just >300 cases, perhaps an unexpected outcome given the state's high rates of HIV and other sexually transmitted infections (STIs). We aimed to describe the local outbreak within two health centers in the New Orleans region, partnering with the Louisiana Department of Health to offer additional statewide data. We reviewed charts of persons testing positive for mpox in New Orleans from July to November 2022 at two local health centers that together accounted for half of local cases.

Methods: This study included 10 543 women from the 2003-2016 National Health and Nutrition Examination Survey.
Mortality in COVID-19 cases was strongly associated with progressive lung inflammation and eventual sepsis. There is mounting evidence that live attenuated vaccines commonly administered during childhood, also provide beneficial non-specific immune effects, including reduced mortality and hospitalization due to unrelated infections. It has been proposed that live attenuated vaccine-associated non-specific effects are a result of inducing trained innate immunity to function more effectively against broader infections.

We recently reported significant yet modest effects of HIV under highly active antiretroviral therapy (ART) on the oral microbiome (bacterial and fungal) in a large cohort of HIV-positive (HIV) and matched HIV-negative (HIV) individuals. As it was unclear whether ART added to or masked further effects of HIV on the oral microbiome, the present study aimed to analyze the effects of HIV and ART independently, which also included HIV subjects on preexposure prophylaxis (PrEP) therapy.

Similar to cervical cancer, anal cancer is preceded by high-grade squamous intraepithelial lesions (HSILs). Treatment for cervical HSIL reduces progression to cervical cancer; however, data from prospective studies of treatment for anal HSIL to prevent anal cancer are lacking.

Studies showed the onset of HPV carcinogenesis may be induced by oxidative stress affecting the host immune system. The association between antioxidants and oncogenic HPV remains unclear.

At the 7th World Workshop on Oral Health & Disease in HIV/AIDS in India in 2014, some aspects of the human microbiome were discussed, and research questions formulated. Since that time, there have been major advances in technology, which have stimulated a number of publications on many aspects of the human microbiome, including the oral cavity.

We tested the hypothesis that human herpesviruses might cooperate with HPV to promote the development of cervical dysplasia, an early indicator of cervical cancer development.
Methods: This study used archived specimens from a cohort of human immunodeficiency virus (HIV)-seropositive women seeking gynecological care at the Medical Center of New Orleans, Louisiana.
Persons infected with HIV are particularly vulnerable to a variety of oral microbial diseases. Although various study designs and detection approaches have been used to compare the oral microbiota of HIV-negative and HIV-positive persons, both with and without highly active antiretroviral therapy (HAART), methods have varied, and results have not been consistent or conclusive. The purpose of the present study was to compare the oral bacterial community composition in HIV-positive persons under HAART to an HIV-negative group using 16S rRNA gene sequence analysis.

The standard method samples were collected by a clinician at a routine pelvic examination. Self-samples were taken at home and mailed to the clinical laboratory.
View Article and Find Full Text PDFSince their discovery as the etiologic agents of cervical cancer in the mid-1970s, human papillomaviruses (HPVs) have been linked with a growing number of epithelial-derived tumors, including head and neck squamous cell carcinomas. HPV demonstrates a particular predilection for causing tumors of the oropharynx, with the majority of cases involving infection with high-oncogenic risk HPV-16. People living with HIV are at increased risk of infection with HPV- and HPV-related oral complications even with adequate control of their HIV infection with antiretroviral therapy.

Like HPV, Epstein-Barr virus (EBV) is a common pathogen with the capacity to promote epithelial neoplasms. We examined the association between cervical EBV, hrHPV, and cytology in female sex workers in Nairobi, Kenya.

Further, to test correlates of reporting that self-collection is preferred over Pap testing. Finally, to determine the prevalence of any of 13 high-risk HPV types among this population and the correlates of testing positive.

Methods: Among 398 women, a validated assay tested self-collected cervicovaginal samples for 37 HPV types. Three economic strata were created based on household income: below the federal poverty level for 1 person, between the FPLs for families of 1 to 4 persons, and above the FPL for a family of 4.
Human papilloma virus (HPV) is a common virus that can cause genital warts and certain cancers. The HPV vaccine is effective in preventing many HPV-associated diseases, however, vaccination rates suggest many remain unprotected. This study examined successful strategies used by physicians to improve HPV vaccination rates.

A 35 year old woman with past medical history of hypertension presented to the emergency department with chief complaint of severe abdominal pain for one week. The abdominal pain was located in the epigastrium and described as "cramping" and "intermittent". The pain intensity was quantified initially as 6 out of 10 on the pain scale.

The objective of this study was to investigate human immunodeficiency virus (HIV)-infected women for an association between M. genitalium and cervicitis, a putative mechanism for enhanced HIV transmission efficiency to an uninfected partner.
View Article and Find Full Text PDFObjectives: To describe women's comfort levels and perceptions about their experience self-collecting cervicovaginal swabs for human papillomavirus (HPV) testing, to determine whether nurse-guided patient navigation increases the odds of women receiving a traditional Papanicolaou (Pap) test after HPV screening, and to test the hypothesis that women testing positive for oncogenic HPV would be more likely to have a subsequent Pap test than those testing negative.
Methods: A total of 400 women were recruited from 8 rural Appalachian counties, in 2013 and 2014. After completing a survey, women were provided instructions for self-collecting a cervicovaginal swab.
