    IntroductionWhile the U.S. has seen a sustained rise in STI cases over the past decade, the impact of the COVID-19 on STIs and HIV is unclear.MethodsTo examine the short- and medium-term impacts of COVID-19 and HIV and STI testing and diagnosis, we compared pre-pandemic trends to three periods of the pandemic: early- pandemic, March-May 2020; mid-pandemic June 2020-May 2021; and late-pandemic, June 2021-May 2022. We compared average number of monthly tests and diagnoses, overall and by gender, as well as the monthly change (slope) in testing and diagnoses.ResultsWe find that after decreases in average monthly STI and HIV testing and diagnoses during the early- and mid-pandemic, cases were largely back to pre-pandemic levels by the late-pandemic, with some variation by gender.ConclusionChanges in testing and diagnoses varied by phase of the pandemic. Some key populations may require additional outreach efforts to attain pre-pandemic testing levels

    Sexual violence is associated with increased risk of HIV acquisition/transmission in women. Forced sex can result in physical trauma to the reproductive tract as well as severe psychological distress. However, immuno-biological mechanisms linking sexual violence and HIV susceptibility are incompletely understood. Using the Women\u27s Interagency HIV Study repository, a total of 77 women were selected to form 4 groups, stratified by HIV serostatus, in the following categories: 1) no sexual abuse history and low depressive symptom score (below clinically significant cut-off, score

    Background: Controlled pharmacokinetic (PK) studies in United States populations have defined categories of tenofovir-diphosphate (TFV-DP) in dried blood spots (DBS) for various pre-exposure prophylaxis (PrEP) adherence targets. It is unknown how these categories perform in other populations. Therefore, we evaluated the sensitivity and specificity of these PK-derived categories compared to daily medication electronic adherence monitoring (MEMS) data among East African men and women using daily PrEP.Methods: Participants were enrolled as members of HIV serodiscordant couples as part of an open-label PrEP study in Kenya and Uganda. Blood samples were taken at quarterly visits and stored as DBS, which were analyzed for TFV-DP concentrations.Results: Among 150 samples from 103 participants, MEMs data indicated that 87 (58%) took ≥4 doses and 62 (41%) took ≥6 per week consistently over the 4 weeks prior to sample collection. Sensitivities of DBS TFV-DP levels were 62% for the ≥4 doses/week category (≥700 fmol/punch TFV-DP) and 44% for the ≥6 doses/week category (≥1050 fmol/punch TFV-DP); specificities were 86 and 94%, respectively. There were no statistically significant differences in these sensitivities and specificities by gender.Conclusion: In this sample of East African PrEP users, categories of TFV-DP concentrations developed from directly observed PrEP use among United States populations had high specificity but lower than expected sensitivity. Sensitivity was lowest when MEMS data indicated high adherence (i.e., ≥6 doses/week). PrEP studies and implementation programs should carefully consider the sensitivity and specificity of the TFV-DP levels used for adherence feedback

    Thesis (Ph.D.)--University of Washington, 2018HIV incidence remains disproportionately high for women, particularly young women, in Sub-Saharan Africa; women are also at heightened risk while pregnant, which may account for a substantial portion of their adult lives. Although HIV pre-exposure prophylaxis (PrEP) in pill form is known to be efficacious for women, there remain unanswered questions about adherence in open-label and real-world settings, as well as regarding the effectiveness of PrEP during pregnancy. In the work presented in this dissertation, we first examined how women used PrEP in an open-label demonstration project and particularly, how adherence was related to HIV risk behaviors. Second, to better assess adherence, we evaluated the sensitivity and specificity of a biomarker among East African men and women using PrEP. Finally, we examined the effect of pregnancy on PrEP concentrations. First, we found that women in known serodiscordant relationships were able to take PrEP effectively; more than half took PrEP during their entire risk period, with ≥6 doses for most weeks when on PrEP. HIV incidence was reduced 93% (95% CI 77%-98%) for all women and 91% (95% CI 29%-99%) among women under 25 years old. In further analysis, we found evidence of four adherence trajectories and two risk behavior trajectories over the first six months of PrEP use. Women with a declining risk behavior trajectory were more likely to have a declining adherence trajectory, while women with steady risk were more likely to have high steady adherence; this supports the idea of prevention-effective adherence, which optimizes PrEP use. In the second aim, we found low sensitivities for the adherence biomarker tenofovir-diphosphate, using thresholds established in U.S. populations. Adherence counseling based on biomarkers should carefully consider the trade-offs between sensitivity and specificity. Finally, we found that concentrations of PrEP are significantly lower in pregnant women compared to non-pregnant women, as well as during pregnancy compared to pre-pregnancy, after adjusting for adherence. Additional pharmacology and epidemiology studies are needed to determine if PrEP dosing should be altered to sustain systemic levels of tenofovir during pregnancy

    No full text
    Renal artery pseudoaneurysms and arteriovenous fistulae most often occur as an iatrogenic complication. The article discusses a case of a patient diagnosed with an arteriovenous fistula and a pseudoaneurysm. A 64-year-old woman was admitted to the hospital due to nonspecific pain in the lumbar region. Imaging showed a typical picture of clear cell renal carcinoma. The patient was qualified for surgical treatment. After tumor resection, the patient developed microhematuria. Arteriovenous fistula and renal pseudoaneurysm were diagnosed using Doppler and computed tomography scans. The patient was qualified for arteriography with simultaneous embolization of the lesion. A follow-up evaluation confirmed the exclusion of aneurysm and fistula. Treatment outcomes were monitored using Doppler ultrasound. Doppler ultrasonography is the first method of choice in detecting and monitoring renal artery irregularities. Safety, non-invasiveness and easy access to this tool make it play a key role in the diagnosis of renal artery fistulas and pseudoaneurysms

W pracy omówiono przypadek chorej, u której w badaniu ultrasonograficznym i tomografii komputerowej rozpoznano przetokę tętniczo-żylną i tętniaka rzekomego, zlokalizowane w nerce prawej, a następnie leczonej metodami wewnątrznaczyniowymi. Sześćdziesięcioczteroletnia kobieta została przyjęta do szpitala z powodu niespecyficznych dolegliwości bólowych w okolicy lędźwiowej. Badania obrazowe wykazały typowy obraz dla jasnokomórkowego raka nerki. Chorą zakwalifikowano do leczenia chirurgicznego. Po resekcji klinowej u pacjentki obserwowano okresowy krwinkomocz. Za pomocą badania dopplerowskiego i tomografii komputerowej zdiagnozowano przetokę tętniczo-żylną i tętniaka rzekomego nerki prawej. Chorą zakwalifikowano do arteriografii z równoczasową embolizacją. Po zabiegu embolizacji badania kontrolne potwierdziły wyłączenie tętniaka i przetoki z krążenia. Wyniki leczenia monitorowano za pomocą badań dopplerowskich. Ultrasonografia dopplerowska jest metodą z wyboru w wykrywaniu i monitorowaniu nieprawidłowości tętnic nerkowych. Bezpieczeństwo, nieinwazyjność i dostępność badania sprawiają, że odgrywa ono kluczową rolę w diagnozowaniu przetok tętnic nerkowych i pseudotętniaków

    Background: Sexual violence is associated with increased risk for HIV acquisition/transmission in women. Chronic exposure to sexual violence can result in genital tract trauma and psychosocial stress subsequently affecting immune functions. We hypothesized that women with chronic sexual abuse and depression would have dysregulated genital tract immune mediators that can affect HIV risk. Methods: Using the Women\u27s Interagency HIV Study (WIHS) repository, we identified 4 groups of HIV+ and HIV- women (8-10/group) representing chronic sexual abuse exposure and depression (CES-D score \u3e 16): 1) no history of sexual abuse at baseline or depression (Control); 2) no history of sexual abuse at baseline but current depression (Depression); 3) chronic sexual abuse but no depression (Abuse); 4) chronic sexual abuse with current depression (Abuse+Depression). Cytokines (IL-6, IL-8, IL-1α, IL-1β, TNF-α, TGF-β), chemokines (MIP-3α, IP-10, MCP-1) and antimicrobials (Secretory leukocyte protease inhibitor (SLPI), Elafin, and Human beta defensin 2 (HBD-2)) were analyzed in cervical vaginal lavage (CVL) samples using ELISA. Linear regression was used to model levels of biomarkers with both depression and abuse as predictors. Models were run separately for HIV+ and HIV- women, with CD4 counts and viral load as covariates for HIV+ group. Results: In HIV- women reporting Abuse+Depression we found significantly higher levels of IP-10 compared to Control and Depression groups. Abuse+Depression group also had significantly higher levels of IL-1α but significantly lower levels of TGF-β, compared to Depression group. In HIV+ women, significantly lower levels of MIP-3α were found in the Abuse+Depression group compared to Controls whereas MCP-1 levels were highest in the Abuse group. When comparing by HIV status, HIV+ women reporting depression had significantly higher levels of IP-10 compared to HIV- women reporting depression. MCP-1 levels were significantly higher in HIV+ Abuse group compared to HIV- Abuse group. However, for MIP-3α, levels were significantly lower in HIV+ Abuse+Depression compared to HIV- Abuse+Depression. In HIV- women, there was evidence of an interaction between abuse and depression for IL-1a and IP-10. Conclusions: Our data suggests genital immune biomarkers are affected by chronic sexual abuse and HIV status. Further studies are needed to understand biological mechanisms of HIV acquisition/transmission in these women
