We studied cervicovaginal β-/γ-human papillomavirus (HPV) and their relationship to cervical precancer in women with HIV (WWH); having previously reported strong positive associations of β-/γ-HPV with incident head and neck cancer in the general population. Cases (N=124) had cervical intraepithelial neoplasia (CIN)-3 or CIN-2. Controls (N=247) were individually matched 2:1 to cases.

Methods: An inquiry curriculum was developed in 2019 and included lectures on biostatistics and research design with small group discussions of clinical research papers directly related to the core sciences content. Students' perceptions and pass rates between students who did (2019 cohort) and did not (2018 cohort) undergo the curriculum were compared.
Background: In 2010-2014, the San Francisco Department of Public Health (SFDPH) established programs to rapidly link people with human immunodeficiency virus (PWH) to care and offer antiretroviral therapy (ART) at human immunodeficiency virus (HIV) diagnosis. Such programs reduced the number of PWH out of care or with detectable HIV viral load (ie, uncontrolled HIV infection). We investigated the role of social determinants of health (SDH) on uncontrolled HIV.

Methods: We reanalyzed data from 34 studies including 16 164 individuals in 6 risk groups defined by human immunodeficiency virus (HIV) status, sex, and male sexuality: men who have sex with men (MSM) and people with HIV (MSMWH), HIV-negative MSM, women with HIV (WWH), HIV-negative women, men who have sex with women (MSW) with HIV (MSWWH), and HIV-negative MSW. We used Markov models to estimate incidence and clearance of 13 hrHPV types and their determinants.
Background: Age-specific data on anal, and corresponding cervical, human papillomavirus (HPV) infection are needed to inform female anal cancer prevention.
Methods: We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology.
Integrase inhibitor-based (INSTI) antiretroviral therapy (ART) regimens are preferred for most people with HIV (PWH). We examined factors associated with INSTI use among PWH in San Francisco who started ART in 2009-2016. PWH who experienced homelessness were less likely, and older PWH were more likely, to use an INSTI.

Our objective was to measure the sensitivity, specificity, and agreement between multiple causes of deaths from death certificates obtained from the National Death Index (NDI) and causes determined by expert physician review.
Methods: Physician specialists determined the cause of death using information collected from the medical records of 50 randomly selected HIV-infected people who died in San Francisco from July 1, 2016, through May 31, 2017.

Despite elevated mortality in people with HIV (PWH) using drugs, drug-related deaths are poorly characterized. Among 6764 drug-related deaths, methamphetamine was more common in PWH than others. One in 4 deaths in PWH involved acute infection.
View Article and Find Full Text PDFObjectives: We investigated whether the effect of smoking on the incidence of smoking-related cancers differs by HIV-infection status, if sex modifies the impact of risk factors for smoking-related cancers, and the sex-specific attributable risk of smoking on cancer incidence.
Design: Data from two large prospective studies in the United States were analyzed: 6789 men in the Multicenter AIDS Cohort Study from 1984 through 2018 and 4423 women in the Women's Interagency HIV Study from 1994 through 2018.
Methods: Incidence rates, relative risks, and adjusted population attributable fractions (PAFs) were calculated for smoking-related cancers.
Background: Primary human papillomavirus (HPV) screening (PHS) utilizes oncogenic human papillomavirus (oncHPV) testing as the initial cervical cancer screening method and typically, if positive, additional reflex-triage (eg, HPV16/18-genotyping, Pap testing). While US guidelines support PHS usage in the general population, PHS has been little studied in women living with HIV (WLWH).
Methods: We enrolled n = 865 WLWH (323 from the Women's Interagency HIV Study [WIHS] and 542 from WIHS-affiliated colposcopy clinics).
Background: Persons living with human immunodeficiency virus (HIV; PLWH) experience a high burden of cancer. It remains unknown which cancer types are reduced in PLWH with earlier initiation of antiretroviral therapy (ART).
Methods: We evaluated AIDS-free, ART-naive PLWH during 1996-2014 from 22 cohorts participating in the North American AIDS Cohort Collaboration on Research and Design.
For people living with HIV, lack of adherence to antiretroviral therapy (ART) is a serious problem and frequently results in HIV disease progression. Reasons for non-adherence include concomitant psychosocial health conditions - also known as syndemic conditions - such symptoms of depression or posttraumatic stress disorder (PTSD), past physical or sexual abuse, intimate partner violence (IPV), stimulant use, and binge drinking. The aim of this study was to investigate the association between syndemic conditions and medication adherence.

In San Francisco, immediate antiretroviral therapy (ART) at HIV diagnosis was piloted in 2013-2014 and expanded citywide in 2015 in a rapid start initiative to link all new diagnoses to care within 5 days and start ART at the first care visit.
Methods: HIV providers and linkage navigators were trained on a rapid start protocol with sites caring for vulnerable populations prioritized.
Background: San Francisco has implemented several programs addressing the needs of two large vulnerable populations: people living with HIV and those who are homeless. Assessment of these programs on health outcomes is paramount for reducing preventable deaths.
Methods: Individuals diagnosed with HIV/AIDS and reported to the San Francisco Department of Public Health HIV surveillance registry, ages 13 years or older, who resided in San Francisco at the time of diagnosis, and who died between January 1, 2002, and December 31, 2016 were included in this longitudinal study.
Objective: San Francisco, California, has experienced a 44% reduction in new HIV diagnoses since 2013 supported by its 'Getting to Zero' initiative; however, the age-adjusted mortality rate in people with HIV (PWH) has not decreased. We sought to identify factors associated with death among PWH in San Francisco.
Design: Population-based incidence-density case-control study.
Background: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer.
Methods: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018.

Background: The comparative effectiveness of pre- and post-exposure prophylaxis (PrEP and PEP) for men who have sex with men (MSM) is unclear.
Setting: We conducted a case-control study of MSM who were initially HIV-uninfected during September 1, 2012-June 30, 2016 at San Francisco's only municipal sexually transmitted diseases (STDs) clinic.
Methods: Each case was matched with up to 3 controls based on age, baseline visit date, and follow-up time.
Background: People living with human immunodeficiency virus (HIV; PLWH) have a markedly elevated anal cancer risk, largely due to loss of immunoregulatory control of oncogenic human papillomavirus infection. To better understand anal cancer development and prevention, we determined whether recent, past, cumulative, or nadir/peak CD4+ T-cell count (CD4) and/or HIV-1 RNA level (HIV RNA) best predict anal cancer risk.
Methods: We studied 102 777 PLWH during 1996-2014 from 21 cohorts participating in the North American AIDS Cohort Collaboration on Research and Design.
Objective: The authors assessed the association of physical function, social variables, functional status, and psychiatric co-morbidity with cognitive function among older HIV-infected adults.
Design: From 2012-2014, a cross-sectional study was conducted among HIV-infected patients ages 50 or older who underwent comprehensive clinical geriatric assessment.
Setting: Two San Francisco HIV clinics.
Background: Research is needed to better understand relations between immunosuppression and HIV viraemia and risk for non-Hodgkin lymphoma, a common cancer in people living with HIV. We aimed to identify key CD4 count and HIV RNA (viral load) predictors of risk for non-Hodgkin lymphoma, overall and by subtype.
Methods: We studied people living with HIV during 1996-2014 from 21 Canadian and US cohorts participating in the North American AIDS Cohort Collaboration on Research and Design.
Background: Cancer survivors are at increased risk for subsequent primary cancers. People living with HIV are at increased risk for AIDS-defining and non-AIDS-defining cancers, but little is known about their risk of first versus second primary cancers. We identified first and second primary cancers that occurred in above population expected numbers among people diagnosed with HIV in San Francisco, and compared first and second cancer incidence across five time periods that corresponded to important advances in antiretroviral therapy.

Background: HIV-positive women are at substantial risk of HPV-associated cervical neoplasia caused by high-risk (HR) HPVs. Methylation of the HPV genome is associated with cervical intraepithelial neoplasia grade 3 (CIN3) in HIV-negative women, yet it is unknown whether this holds true for HIV-positive women.
Methods: We designed a case-control study within the Women's Interagency HIV Study (WIHS) cohort comparing HIV-positive CIN3 cases ( = 72) to HIV-positive controls without detectable CIN2.
Objective: Recent studies reported a lower human papillomavirus 16 (HPV16) prevalence in cervical precancer among African American than Caucasian women in the general population. We assessed this relationship in women with HIV.
Design: Women living with or at risk for HIV in the Women's Interagency HIV Study were followed semi-annually with Pap tests, colposcopy/histology (if indicated), and collection of cervicovaginal lavage samples for HPV testing by PCR.
