Utilization of a Third-party Partnership in Tele-genetic Risk Assessment Program in Genitourinary Oncology.

OBJECTIVE: To meet the increasing demands of genetic risk assessment for genitourinary cancers due to expanded clinical guidelines, we established an academic/industry partnership to create a streamlined workflow to overcome the barriers to access to care. MATERIALS AND METHODS: Genome Medical offers multilingual genetic counseling. A pilot program evaluated patients at risk for hereditary genitourinary syndromes. Between January 1, 2020 and January 07, 2022, all patients in need of germline testing were offered hybrid in-clinic telehealth pre-test counseling and when indicated, genetic testing. Post-test counseling was offered based on results and encouraged if positive. Testing results, patient satisfaction, and costs were evaluated. RESULTS: A total of 146 of 182 (80.0%) patients agreed to participate, with 130 (89.0%) completing pre-test counseling. Median age was 65 (range 22-95), with 91% being male and approximately 60% having prostate cancer. The median time from referral to pre-test counseling was 11 days (IQR 7-20). After assessment, testing was recommended for 127 (97.7%) of which 123 (96.8%) completed testing. The median time from testing to result release was 15 days (IQR 10-20.8). Forty (32.5%) had post-test counseling. Reimbursement by private insurers increased annually from $17.2 to $52.4. Patient satisfaction was high with a mean Genetic Counselor Satisfaction Scale of 27.9 out of 30. CONCLUSION: Our program provided high patient satisfaction, rapid access to genetic counseling, prompt genetic testing, timely release of results, and was cost-effective compared to traditional models. This approach is scalable across community and academic settings and across cancer types.

Molecular basis for the activation of the Fatty Acid Kinase complex of Staphylococcus aureus.

Gram-positive bacteria utilize a Fatty Acid Kinase (FAK) complex to harvest fatty acids from the environment. The complex, consisting of the fatty acid kinase, FakA, and an acyl carrier protein, FakB, is known to impact virulence and disease outcomes. However, FAK's structure and enzymatic mechanism remain poorly understood. Here, we used a combination of modeling, biochemical, and cell-based approaches to establish critical details of FAK activity. Solved structures of the apo and ligand-bound FakA kinase domain captured the protein state through ATP hydrolysis. Additionally, targeted mutagenesis of an understudied FakA Middle domain identified critical residues within a metal-binding pocket that contribute to FakA dimer stability and protein function. Regarding the complex, we demonstrated nanomolar affinity between FakA and FakB and generated computational models of the complex's quaternary structure. Together, these data provide critical insight into the structure and function of the FAK complex which is essential for understanding its mechanism.

Hardware failure for anterior chest wall and costal cartilage injuries: A single-center experience.

BACKGROUND: Often missed in blunt chest wall injury, costal cartilage injuries can cause chest wall instability, refractory pain, and deformity. Notably, there is only a small amount of evidence regarding hardware performance when applied to costal cartilage. In a prior multicenter study, hardware failure rate was found to be approximately 3% following surgical stabilization of rib fractures (SSRFs) for all fracture locations. The aim of the current study was to evaluate hardware performance for costal cartilage injuries. METHODS: All patients undergoing SSRF performed at our institution from 2016 to 2022 were queried, including both acute and chronic injuries. Both radiographic and clinical follow-up were retrospectively reviewed to evaluate for hardware failure defined as plate fracture, malposition, or screw migration following cartilage fixation. RESULTS: After screening 359 patients, 43 were included for analysis. Mean age was 64 years, and 67% of patients were male. Median number of fractures per patient was 7 with 60% of patients sustaining a flail chest injury pattern. Median total plates per operation was 6 and median costal cartilage plates was 3. In total, 144 plates were applied to the costal cartilage for the group. Mean follow-up was as follows: clinical 88 days, two-view plain radiography 164 days, and chest computed tomography 184 days. Hardware failure was observed in 3 of 144 plates (2.1%), in three separate patients. Two cases were asymptomatic and did not require intervention. One patient required revisional operation in the acute setting. CONCLUSION: In our institution, hardware failure for costal cartilage fractures was observed to be 2.1%. This aligns with prior reports of hardware failure during SSRF for all injury locations. Surgical stabilization of anterior and cartilaginous chest wall injury with appropriate plate contouring and fixation technique appears to provide adequate stabilization with a relatively low rate of hardware malfunction. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level V.

A 3-year Retrospective Review of Contraceptive Initiation, Continuation, Switching, and Pregnancy Among Adolescents and Young Adults.

PURPOSE: To understand contraceptive use patterns (initiation, switching, discontinuation) as well as associations with pregnancy in adolescents and young adults attending a teen family planning clinic. METHODS: We performed a chart review of adolescent and young adult patients (ages 12-20) attending a teen family planning clinic in Atlanta, GA between January 1, 2017, and December 31, 2019. Using a standardized abstraction form with quality controls, we collected available data on contraceptive methods used and pregnancy test results during the 3-year period. We analyzed contraceptive use patterns descriptively. We calculated and compared pregnancy incidence according to different contraceptive switch patterns. RESULTS: Our sample included 2,798 individuals who initiated 2,358 prescribed methods. The most commonly prescribed methods of contraception were the contraceptive injection (28.3%), etonogestrel implant (23.5%) and combined hormonal pill (23.2%). There were 599 discontinuations of prescribed methods; side effects like bleeding and headache were the most cited reasons for discontinuation. Most (75.8%) initiated a moderately or highly effective method after discontinuing a moderately or highly effective method. The incidence rate of pregnancy was highest for those who had discontinued an intrauterine device or implant and started a shorter-acting contraceptive method. DISCUSSION: Employing patient-centered contraceptive counseling that incorporates contraceptive experiences in addition to facts and allows for exploration and change may be valuable for young people. Successful navigation of contraceptive switches may require additional attention, education, and strategy, which could include hypothetical problem solving, close follow-up, and telehealth or virtual care.

Chlamydia and Gonorrhea Testing Patterns Among Women with and Without Serious Mental Illness.

Rates of the sexually transmitted infections (STIs) Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) have risen in women by 13% and 40%, respectively, since 2015. Women with Serious Mental Illness (SMI) are at disproportionate risk for STIs. A retrospective chart review was performed at a safety-net healthcare system in the Southeastern United States (US) from 2014 to 2017. CT/GC positivity rates did not differ between the general and SMI populations (6.6% vs. 6.5% for CT and 1.8% vs. 2.2% for GC, respectively). Emergency Medicine accounted for more positive STI test results in SMI patients than the general population (25.2% vs. 19.1% for CT, 47.8% vs. 35.5% for GC, respectively). SMI patients received large portions of STI care in emergency settings, where follow-up is poor. Point of Care (POC) testing could improve care in this setting, and mental healthcare providers must address sexual health with patients who otherwise may not receive this care.

The COVID-19 pandemic's intersectional impact on work life, home life and wellbeing: an exploratory mixed-methods analysis of Georgia women's experiences during the pandemic.

BACKGROUND: Women have been especially impacted by the COVID-19 pandemic. This exploratory study aimed to characterize women's adverse experiences related to their work, home lives, and wellbeing during the height of the COVID-19 pandemic and to describe demographic differences of those lived experiences. METHODS: Using the validated Epidemic-Pandemic Impacts Inventory, we collected data from reproductive-aged women in the state of Georgia about their exposure to adverse events during the pandemic. A latent class analysis (LCA) was performed to identify subgroups of women reporting similar adverse experiences and describe their sociodemographic characteristics. An optional open-ended question yielded qualitative data that were analyzed thematically and merged with subgroup findings. Data were collected from September 2020 to January 2021. RESULTS: 423 individuals aged 18-49 completed the survey with 314 (74.2%) providing qualitative responses. The LCA yielded 4 subgroups: (1) a "low exposure" subgroup (n = 123, 29.1%) with relatively low probability of adverse experiences across domains (e.g. financial insecurity, health challenges, barriers to access to healthcare, intimate partner violence (IPV)); (2) a "high exposure" subgroup (n = 46, 10.9%) with high probability of experiencing multiple adversities across domains including the loss of loved ones to COVID-19; (3) a "caregiving stress" subgroup (n = 104, 24.6%) with high probability of experiencing challenges with home and work life including increased partner conflict; and (4) a "mental health changes" subgroup (n = 150, 35.5%) characterized by relatively low probability of adverse experiences but high probability of negative changes in mental health and lifestyle. Individuals in subgroups 1 and 4, which had low probabilities of adverse experiences, were significantly more likely to be non-Hispanic white. Individuals in subgroup 2 were more likely to identify with a sexual or racial/ethnic minority population. Inductive coding of qualitative data yielded themes such as stress, mental health, financial impact, and adaptation/resilience, providing context for pandemic-related adversity. CONCLUSION: Though many individuals in our sample experienced hardship, minority populations were unequally impacted by pandemic-related adversity in work life, home life, and wellbeing. Recovery and future emergency preparedness efforts in Georgia must incorporate support mechanisms for mental health and IPV, focusing especially on the intersectional needs of racial, ethnic, and sexual minorities.

The COVID-19 pandemic's impact on sexual and reproductive health in Georgia, USA: An exploration of behaviors, contraceptive care, and partner abuse.

OBJECTIVE: Assessing access to sexual and reproductive health care during the COVID-19 pandemic, experiences with intimate partner violence (IPV), and exploring sociodemographic disparities STUDY DESIGN: From September 2020 to January 2021, we recruited 436 individuals assigned female at birth (18-49 years.) in Georgia, USA for an online survey. The final convenience sample was n = 423; a response rate could not be calculated. Survey themes included: sociodemographic and financial information, access to contraceptive services/care, IPV, and pregnancy. Respondents who reported a loss of health insurance, difficulty accessing contraception, barriers to medical care, or IPV were characterized as having a negative sexual and reproductive health experience during the pandemic. We explored associations between sociodemographic variables and negative sexual and reproductive health experiences. RESULTS: Since March 2020, 66/436 (16%) of respondents lost their health insurance, and 45% (89/436) reported income loss. Of our sample, 144/436 people (33%) attempted to access contraception. The pandemic made contraceptive access more difficult for 38/144 (26%) of respondents; however, 106/144 (74%) said it had no effect or positive effect on access. Twenty-one respondents reported IPV (5%). COVID-19 amplified negative views of unplanned pregnancy. Seventy-six people (18%) reported at least 1 negative sexual and reproductive health experience during the pandemic; people in an urban setting and those identifying as homo/bisexual were more likely to report negative experiences (24%, 28% respectively). CONCLUSION: Urban and sexual minority populations had negative sexual and reproductive health experiences during COVID-19 more than their counterparts. The pandemic has shifted perspectives on family planning, likely due to the diverse impacts of COVID-19, including loss of health insurance and income. IMPLICATION: Females across Georgia reported varying impacts of the COVID-19's pandemic on their sexual and reproductive health care. These findings could be utilized to propose recommendations for care and intimate partner violence support mechanisms, tailored to urban and sexual minority populations.

Trends in Chlamydia and Gonorrhea Testing and Positivity Rates in a Safety Net Hospital in Georgia: 2014 to 2017.

BACKGROUND: Sexually transmitted infections (STIs) in the United States continue to increase at an alarming rate. Since 2015, reported cases of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC), the 2 most prevalent reportable STIs, have increased by 19% and 56%, respectively. Characterizing testing patterns could elucidate how CT/GC care and positivity have evolved over time in a high-risk urban setting and illustrate how patients use the health care system for their STI needs. METHODS: Using electronic medical record data from a large safety net hospital in Georgia, patient demographics and clinical characteristics were extracted for all nucleic acid amplification tests ordered from 2014 to 2017 (n = 124,793). Descriptive statistics were performed to understand testing patterns and assess positivity rates. RESULTS: Annual nucleic acid amplification test volume grew by 12.0% from 2014 to 2017. Obstetrics/gynecology consistently accounted for half of all tests ordered; volume in emergency medicine grew by 45.2% (n = 4108 in 2014 to n = 5963 in 2017), whereas primary care volume fell by -4.3% (n = 4186 in 2014 to n = 4005 in 2017). The largest number of positive results was detected among 15- to 24-year-olds. The positivity of CT was higher among females, and GC among males. The percent positivity of CT remained stable (range, 6.4%-7.0%). The percent positivity of GC increased from 2.7% to 4.3% over time. CONCLUSIONS: Testing volume in emergency medicine has increased at a faster rate than other specialties; point-of-care testing could ensure more accurate treatment and improve antibiotic stewardship. The rates of CT/GC were high among adolescents and young adults. Tailored approaches are needed to lower barriers to care for this vulnerable population.

Analysis of Postpartum Uptake of Long-Acting Reversible Contraceptives Before and After Implementation of Medicaid Reimbursement Policy.

OBJECTIVES: The postpartum period is a time of high unmet contraception need. Providing long-acting reversible contraception (LARC), particularly in the immediate postpartum period, is one strategy to meet contraceptive needs. This practice may also prevent unintended and short interpregnancy interval pregnancies. In recent years, state Medicaid programs have implemented reimbursement policies for LARC use in the inpatient setting. The purpose of this study was to assess the uptake of inpatient postpartum LARCs at a large urban hospital with a sizable Medicaid population, before and after policy implementation. METHODS: Using billing records from January 2015 and December 2017, we extracted data on patient demographics and LARC uptake before Medicaid policy change (2015) and after policy change (2016 and 2017). Implant and intrauterine device insertions were classified as inpatient postpartum (0-7 days after birth), outpatient postpartum (1-8 weeks after) or interval (9+ weeks after). RESULTS: In the 3-year study period, 2091 LARC insertions occurred, of which 700 (33.5%) were inpatient postpartum, 429 (20.5%) outpatient postpartum, and 962 (46.0%) interval. After policy implementation, inpatient postpartum LARC insertions increased from 2.6 per 100 deliveries to 16.8 per 100 deliveries. Significant differences in uptake were seen in Black and Hispanic populations. The number of outpatient postpartum LARCs remained stable and tubal sterilizations decreased. CONCLUSIONS FOR PRACTICE: Implementation of reimbursement policies contributed to a sharp uptake of inpatient postpartum LARCs. Improved access to effective, reversible contraception could reduce the number of unplanned and short interpregnancy interval pregnancies, ultimately lowering rates of maternal morbidity and mortality.

Finding the Gaps in Retesting for Chlamydia and Gonorrhea: Differences Across High-Volume Testing Departments in an Urban Health Care Setting.

BACKGROUND: The Centers of Disease Control and Prevention guidelines recommend that all patients be retested 3 months after a positive chlamydia (CT) or gonorrhea (GC) result. However, retest rates are generally low, and only a quarter of patients return to clinic for retesting. This analysis explored retesting patterns in a high sexually transmitted infection (STI)/human immunodeficiency virus (HIV)-risk setting to illuminate gaps in adherence to guideline recommendations. METHODS: Retrospective chart data from a large urban safety-net institution were analyzed descriptively. Patients who received a positive CT/GC test from January to February 2017 were followed up for at least 4 months to assess if retesting occurred within approximately 3 months. RESULTS: Our sample of 207 patients was primarily non-Hispanic Black (92.8%), younger than 25 years (63.3%) and women (60.4%). Over half had been initially diagnosed with CT, one-third with GC, and one-tenth with both CT and GC. Eighty-nine (43.0%) patients were retested during the observed period; mean time between tests was 2.7 months. Retesting was most common in infectious diseases/HIV primary care (73.6%) and obstetrics/gynecology (44.9%). Patients who were first diagnosed in emergency medicine were significantly less likely to be retested. Retested patients included a large number of HIV-positive men (31 of 89 total) and pregnant women (23 of 54 women). CONCLUSIONS: Forty-three percent of patients were retested within approximately 3 months of their initial positive CT/GC diagnosis, exceeding previously published rates. Nonetheless, in light of the growing STI epidemic, health care systems should prioritize retesting across high-volume testing specialties, rethink retesting models, and facilitate referrals to ensure that patients receive guideline-recommended, comprehensive STI care.

Exploring real-world experiences of early PrEP adopters in southern Germany.

Germany authorized reimbursement for PrEP and established PrEP provider training in 2019, much later than its Western European counterparts. Understanding the lived experiences of early adopters of PrEP could inform the ramp-up phase of PrEP implementation in Germany. The purpose of this study was to explore the experience of southern German men who started PrEP prior to 2019. In Spring 2018, we conducted 13 in-depth interviews with men who have sex with men (MSM) regarding PrEP initiation, adoption and routine care. Transcripts were transcribed, translated, validated, then analysed using thematic content analysis. Participants started PrEP in 2017-2018. They described the security that PrEP provided and the ability to enjoy their sex lives more fully. Some raised concerns about side effects and the lack of long-term data. Users valued a non-judgmental relationship with their providers. Users' aspirations for future HIV prevention included: prescription-free PrEP, decreased dosing frequency, and telemedicine consultations.

Supporting breastfeeding of small, sick and preterm neonates.

Breastfeeding is associated with a risk reduction for several acute and chronic diseases in women and their infants. Health benefits of breastfeeding are especially important for small, sick and preterm infants. The objective of this article is to summarize essential steps for healthcare personnel and facilities to improve breastfeeding practices in this vulnerable population. Health facilities can support breastfeeding through the establishment of breastfeeding-supportive policies, staff training and the design of facilities to support rooming-in. Direct support to breastfeeding includes the provision of counseling to mothers at critical time points, skin-to-skin and kangaroo care, and support of responsive (on-demand) breastfeeding. Where direct breastfeeding is not possible, facilities should show mothers how to express their breastmilk and teach mothers alternative feeding modalities. Medically-indicated supplementation of small, sick and preterm may be needed in certain circumstances.

Who Is Practicing Expedited Partner Therapy and Why? Insights From Providers Working in Specialties With High Volumes of Sexually Transmitted Infections.

BACKGROUND: Expedited partner therapy (EPT), the practice of prescribing antibiotics for sexual partners of patients, is underutilized in Georgia. This qualitative study in a large urban institution aimed to (1) characterize the clinical specialties that predominantly treat sexually transmitted infections (STIs), (2) identify perceived barriers to EPT, and (3) describe strategies to advance routine EPT use. METHODS: Providers in obstetrics/gynecology (OB/GYN), infectious disease (ID), and emergency medicine (EM) were interviewed using a structured discussion guide. Transcripts were double-coded and iteratively analyzed using qualitative content analysis. Barriers and strategies were summarized and supported with quotes from providers (n = 23). RESULTS: Perceived EPT barriers overlapped across OB/GYN, ID, and EM, yet the settings were diverse in their patient populations, resources, and concerns. Providers in OB/GYN were the only ones practicing EPT, yet there was a lack of standardization. Providers in ID noted that an EPT prescription from an ID provider could inadvertently disclose the HIV status of a patient to a sexual partner, posing an ethical dilemma. Providers in EM exhibited readiness for EPT, although routine empiric treatment for index patients in EM (estimated at 90%) gave some providers pause in prescribing for partners: "I do not know what I'm treating." Point-of-care testing could increase providers' confidence in prescribing EPT, yet some worried it could contribute to overutilization of the emergency department as a sexually transmitted infection clinic. All settings prioritized setting-specific training and protocols. CONCLUSIONS: Providers in OB/GYN, ID, and EM report unique hurdles, specific to their settings and patient populations; tailored EPT implementation strategies, particularly provider training, are urgently needed to improve patient/partner outcomes.

Knowledge and practice of induction of lactation in trans women among professionals working in trans health.

BACKGROUND: Breastfeeding is emerging as an important reproductive rights issue in the care of trans and gender nonconforming people. This study sought to understand the tools available to professionals working in the field of trans health to help trans women induce lactation and explore the concept of unmet need. METHODS: In November 2018, we conducted a cross-sectional study which surveyed attendees at the World Professional Association for Transgender Health (WPATH) symposium in Buenos Aires, Argentina. Eligible participants were 18 + years old, had professional experience with transgender populations, were able to complete a survey in English, and were conference attendees. Descriptive data were collected using a 14-item written survey encompassing demographic characteristics, experience in transgender health, and lactation induction in trans women. RESULTS: We surveyed 82 respondents (response rate 10.5%), the majority of whom were healthcare professionals (84%). Average age of respondents was 42.3 years old. They represented 11 countries and averaged 8.8 years of work at 21.3 h/week with trans populations. Healthcare professionals in this sample primarily specialized in general/internal medicine, psychology, endocrinology, and obstetrics/gynecology. One-third of respondents (34%) stated that they have met trans women who expressed interest in inducing lactation. Seventeen respondents (21%) knew of providers, clinics, or programs that facilitated the induction of lactation through medication or other means. Seven respondents (9%) have helped trans women induce lactation with an average of 1.9 trans women in the previous year. Two protocols for lactation induction were mentioned in free text responses and 91% believe there is a need for specialized protocols for trans women. CONCLUSION: This exploratory study demonstrates healthcare professionals' interest in breastfeeding protocols for lactation induction in trans women. Additional studies are needed to capture insights from breastfeeding specialists, e.g. lactation consultants and peripartum nurses, and to understand patients' perspectives on this service.

Perspectives on HIV PrEP care in Germany: qualitative insights from primary care physicians and specialists.

Recently, research has shifted from investigating the effectiveness of HIV pre-exposure prophylaxis (PrEP) to strategizing its implementation. Several European studies have explored physicians' perspectives on implementing PrEP in diverse settings, yet there are no data on the situation in Germany. The purpose of this study was to explore physicians' perspectives on current PrEP care in Germany. From April to July 2018, we conducted 16 semi-structured interviews with HIV providers (HIVPs) and primary care physicians (PCPs). Transcripts were analyzed using thematic content analysis. Physicians showed varying levels of PrEP expertise. Many PCPs lacked knowledge about PrEP. Some PCPs did not support the idea of PrEP as a prophylactic option. Opinions about PCPs' role in PrEP care were diverging, yet most PCPs favored referring PrEP clients to an HIVP or opted for a shared-care arrangement. Perceived problems included stigma and lack of privacy for PrEP care in rural areas. Our findings highlight the need for tailored physician training, which should be addressed in PrEP implementation in Germany.

Guidance on Expedited Partner Therapy: A Content Analysis of Informational Materials for Providers, Pharmacists, Patients, and Partners.

BACKGROUND: The rates of sexually transmitted infections have steadily increased in the United States over the last 5 years. The Centers for Disease Control and Prevention has endorsed the use of expedited partner therapy (EPT) as an evidence-based practice to prevent chlamydial reinfection in index patients and lower barriers to treatment for partners. State health departments release guidance on EPT for providers, but it is unclear if information is available for other key stakeholders, for example, pharmacists, patients, and partners. The primary objective of this study was to conduct a review of state and territory health department websites to ascertain the availability, readability, utility, and content of EPT informational materials. METHODS: A content analysis of 84 EPT informational materials was conducted using validated tools to measure readability, adherence to design standards, and EPT content inclusion. Results were stratified for each target audience. RESULTS: Only 64% of states where EPT is allowable had informational materials available. The materials targeted providers (51.2%) and partners (35.7%). Little information targeted pharmacists (7.1%) or index patients (4.8%). The average reading level was 11th grade. Mean design score was 9.57 points of a possible 13 points. Most provider and pharmacist materials did not meet the content criteria; index and partner materials did not thoroughly describe cost of EPT, how to communicate with sex partners about EPT/chlamydia, or how to fill an EPT prescription. CONCLUSIONS: To better support the uptake of EPT, existing resources for EPT should be improved in their design, readability, content, and availability for all target audiences.

Expert Interviews on Multilevel Barriers in Implementing Expedited Partner Therapy for Chlamydia.

Expedited partner therapy (EPT) is an evidence-based practice in which partners of patients with chlamydia are given antibiotics or a prescription for antibiotics without prior medical evaluation. This practice facilitates partner treatment and prevents reinfection of the patient. EPT remains underutilized due to multilevel implementation barriers. Barriers may exist at the level of legislation, policy, health care system, health care provider (HCP), pharmacist, patient, or partner. Qualitative interviews were performed with 11 EPT experts across the United States to uncover barriers in implementation. Thirty-four barriers were identified and grouped into 1 of 15 themes. The themes that surfaced most frequently were liability and adverse events (policy and HCP level), funding (policy level), electronic medical records (health care system level), and awareness (HCP and pharmacy level). Tailored implementation strategies are needed to increase awareness among HCPs and pharmacists, to establish funding and to streamline processes in health care systems.

Role of ALDH1A1 and HTRA2 expression in CCL2/CCR2-mediated breast cancer cell growth and invasion.

Chemokines mediate immune cell trafficking during tissue development, wound healing and infection. The chemokine CCL2 is best known to regulate macrophage recruitment during wound healing, infection and inflammatory diseases. While the importance of CCL2/CCR2 signaling in macrophages during cancer progression is well documented, we recently showed that CCL2-mediated breast cancer progression depends on CCR2 expression in carcinoma cells. Using 3D Matrigel: Collagen cultures of SUM225 and DCIS.com breast cancer cells, this study characterized the mechanisms of CCL2/CCR2 signaling in cell growth and invasion. SUM225 cells, which expressed lower levels of CCR2 than DCIS.com cells, formed symmetrical spheroids in Matrigel: Collagen, and were not responsive to CCL2 treatment. DCIS.com cells formed asymmetric cell clusters in Matrigel: Collagen. CCL2 treatment increased growth, decreased expression of E-cadherin and increased TWIST1 expression. CCR2 overexpression in SUM225 cells increased responsiveness to CCL2 treatment, enhancing growth and invasion. These phenotypes corresponded to increased expression of Aldehyde Dehydrogenase 1A1 (ALDH1A1) and decreased expression of the mitochondrial serine protease HTRA2. CCR2 deficiency in DCIS.com cells inhibited CCL2-mediated growth and invasion, corresponding to decreased ALDH1A1 expression and increased HTRA2 expression. ALDH1A1 and HTRA2 expression were modulated in CCR2-deficient and CCR2-overexpressing cell lines. We found that ALDH1A1 and HTRA2 regulates CCR2-mediated breast cancer cell growth and cellular invasion in a CCL2/CCR2 context-dependent manner. These data provide novel insight on the mechanisms of chemokine signaling in breast cancer cell growth and invasion, with important implications on targeted therapeutics for anti-cancer treatment.This article has an associated First Person interview with the first author of the paper.

Barriers to Purchasing Condoms in a High HIV/STI-Risk Urban Area.

The Centers for Disease Control and Prevention (CDC) have identified Atlanta, Georgia as a high-risk environment for STI/HIV infection. Condoms are an inexpensive and effective method for preventing STI/HIV infection. The majority of individuals acquire their condoms through purchase, rather than through free condom distribution programs. However, individuals purchasing condoms in stores encounter numerous barriers. This study assessed the environmental and physical barriers surrounding condom purchases in stores in downtown Atlanta. The findings revealed a combination of high environmental and physical barriers, low visibility of condoms in stores and limited selection of safer sex supplies. In the most densely populated area of the city, stores which sold condoms were few (n = 25), equating to 1 store per ~ 7000 people. In 80% of stores, personnel were required in order to access the condoms. In 28% of stores, condoms were hidden underneath the counter. The majority of stores offered only one brand of male condoms with a limited selection of lubricants and no dental dams or internal condoms. Barriers and discomfort surrounding purchasing condoms can contribute to embarrassment, which has a negative impact on condom acquisition and ultimately on condom use. Efforts must be made to lower barriers in Atlanta and make condoms more readily available to high-risk populations. Community advocacy has been effective in removing barriers to condoms. Access can furthermore be improved by: installing condom vending machines in public locations, offering self-check-out in stores that do not have physical barriers and encouraging individuals to order condoms online.

Implementing condom distribution programs in the United States: Qualitative insights from program planners.

With the growing number of sexually transmitted infections (STIs) among young people (15-24) in the US, condom distribution programs (CDP) remain an integral part of prevention strategies. The objective of the study was to gather qualitative insights from CDP planners to inform effective CDP implementation. Ten semi-structured interviews with program planners were conducted via telephone (response rate of 58.8%). Condom distribution channels included site-based distribution (n = 6), web-based distribution (n = 4), and distribution via Uber (n = 1). Site-based distribution programs had distribution networks ranging from 100 to 3500 sites in a given jurisdiction. Planners of site-based CDPs experienced challenges with ensuring quality control at sites and supplying condoms to sites. Web-based CDPs allow individuals to order free condoms online. These CDP planners reported growing demand for this discreet service, particularly among young people. Web-based CDPs leveraged e-mail surveys to collect data on sexual behavior and behavior change, yielding response rates as high as 63%. All CDPs emphasized the importance of supplying a variety of products. Total supplies distributed (male condoms, internal condoms, lubricant sachets) ranged from 16,000 to 45 million per year. Novel channels of distribution should be explored to ensure reach to adolescents and young adults.
