RESUMEN

Allelic variation at the Ptprc gene, which encodes the pan-leukocyte marker CD45/Ly5, is commonly exploited to track hematopoietic reconstitution by flow cytometry in mixed bone marrow chimera transplant experiments. Historically, this was accomplished using bone marrow from C57BL/6 (Ptprcb/CD45.2/Ly5.2) and congenic B6.SJL-PtprcaPepcb/Boy (Ptprca/CD45.1/Ly5.1) mice. Recently, the Jackson Laboratory directly CRISPR-engineered the Ptprca allele in C57BL/6J mice. This new isogenic strain, termed JAXBoy, differs from wild-type C57BL/6J mice by two nucleotides, compared to the biologically significant 37 megabase (Mb) SJL interval retained in B6.SJL-PtprcaPepcb/Boy/J mice. Currently, Ptprc/CD45 variants are identified by flow cytometry or allele-specific real-time PCR, both of which require specialized workflows and equipment compared to standard genotyping of endpoint PCR products by gel electrophoresis. Here, we employed allele-specific oligonucleotides in conjunction with differential incorporation of a long non-specific oligo 5'-tail to allow for simultaneous identification of the Ptprca and Ptprcb alleles using endpoint PCR and gel electrophoresis. This method allows for integration of Ptprc genotyping into standard genotyping workflows, which use a single set of thermocycling and gel electrophoresis conditions. Importantly, the strategy of primer placement and tail addition described here can be adapted to discriminate similar single- or multi-nucleotide polymorphisms at other genomic loci.

RESUMEN

OBJECTIVE: To identify cognitive phenotypes in late-life depression (LLD) and describe relationships with sociodemographic and clinical characteristics. DESIGN: Observational cohort study. SETTING: Baseline data from participants recruited via clinical referrals and community advertisements who enrolled in two separate studies. PARTICIPANTS: Non-demented adults with LLD (n = 120; mean age = 66.73 ± 5.35 years) and non-depressed elders (n = 56; mean age = 67.95 ± 6.34 years). MEASUREMENTS: All completed a neuropsychological battery, and individual cognitive test scores were standardized across the entire sample without correcting for demographics. Five empirically derived cognitive domain composites were created, and cluster analytic approaches (hierarchical, k-means) were independently conducted to classify cognitive patterns in the depressed cohort only. Baseline sociodemographic and clinical characteristics were then compared across groups. RESULTS: A three-cluster solution best reflected the data, including "High Normal" (n = 47), "Reduced Normal" (n = 35), and "Low Executive Function" (n = 37) groups. The "High Normal" group was younger, more educated, predominantly Caucasian, and had fewer vascular risk factors and higher Mini-Mental Status Examination compared to "Low Executive Function" group. No differences were observed on other sociodemographic or clinical characteristics. Exploration of the "High Normal" group found two subgroups that only differed in attention/working memory performance and length of the current depressive episode. CONCLUSIONS: Three cognitive phenotypes in LLD were identified that slightly differed in sociodemographic and disease-specific variables, but not in the quality of specific symptoms reported. Future work on these cognitive phenotypes will examine relationships to treatment response, vulnerability to cognitive decline, and neuroimaging markers to help disentangle the heterogeneity seen in this patient population.

RESUMEN

For over 100 years, psychophysics ..÷ the scientific study between physical stimuli and sensation ... has been successfully employed in numerous scientific and healthcare disciplines, as an objective measure of sensory phenomena. This manuscript provides an overview of fundamental psychophysical concepts, emphasizing pain and research application..÷defining common terms, methods, and procedures.Psychophysics can provide systematic and objective measures of sensory perception that can be used by nursing scientists to explore complex, subjective phenomena..÷such as pain perception. While there needs to be improved standardization of terms and techniques, psychophysical approaches are diverse and may be tailored to address or augment current research paradigms. The interdisciplinary nature of psychophysics..÷like nursing..÷provides a unique lens for understanding how our perceptions are influenced by measurable sensations. While the quest to understand human perception is far from complete, nursing science has an opportunity to contribute to pain research by using the techniques and methods available through psychophysical procedures.

RESUMEN

Breast cancer is now the most commonly diagnosed cancer worldwide. Approximately 30% of those who present with early breast cancer later develop advanced breast cancer (ABC). Additionally, approximately 6% have advanced breast cancer at diagnosis. New treatment options result in an extended lifespan dominated by cycles of deterioration and stable disease. Specialist nurse knowledge is key to multidisciplinary care of people with ABC; however, access to education on ABC for nurses is not universally available in Europe. This paper describes the development and implementation of an online bespoke program on ABC care for specialist and generalist nurses in Europe. The project team is affiliated with the European Oncology Nurses Society (EONS) and comprises specialist breast cancer nurses, oncology nurse academics and breast cancer advocates associated with EUROPA DONNA Turkey, an independent non-profit European breast cancer organisation. The program development involved (1) a systematic review of ABC educational resources for cancer nurses; (2) a modified four-round Delphi study to seek agreement on curriculum content and (3) curriculum development, conversion to an interactive online platform and translation into four European languages. The program evaluation will be guided by Kirkpatrick's framework. The phases described in this short report could guide others involved in developing bespoke cancer education programs.

RESUMEN

OBJECTIVE: Late-life depression (LLD) is characterized by accelerated biological aging. Accelerated brain aging, estimated from structural magnetic resonance imaging (sMRI) data by a machine learning algorithm, is associated with LLD diagnosis, poorer cognitive performance, and disability. We hypothesized that accelerated brain aging moderates the antidepressant response. DESIGN AND INTERVENTIONS: Following MRI, participants entered an 8-week randomized, controlled trial of escitalopram. Nonremitting participants then entered an open-label 8-week trial of bupropion. PARTICIPANTS: Ninety-five individuals with LLD. MEASUREMENTS: A machine learning algorithm estimated each participant's brain age from sMRI data. This was used to calculate the brain-age gap (BAG), or how estimated age differed from chronological age. Secondary sMRI measures of aging pathology included white matter hyperintensity (WMH) volumes and hippocampal volumes. Mixed models examined the relationship between sMRI measures and change in depression severity. Initial analyses tested for a moderating effect of MRI measures on change in depression severity with escitalopram. Subsequent analyses tested for the effect of MRI measures on change in depression severity over time across trials. RESULTS: In the blinded initial phase, BAG was not significantly associated with a differential response to escitalopram over time. BAG was also not associated with a change in depression severity over time across both arms in the blinded phase or in the subsequent open-label bupropion phase. We similarly did not observe effects of WMH volume or hippocampal volume on change in depression severity over time. CONCLUSION: sMRI markers of accelerated brain aging were not associated with treatment response in this sequential antidepressant trial.

RESUMEN

BACKGROUND: Carpal tunnel release can stop the progression of idiopathic median neuropathy at the wrist (carpal tunnel syndrome). Intermittent symptoms tend to resolve after surgery, but loss of sensibility can be permanent. Both pathophysiology (severe neuropathy) and mental health (symptoms of despair or worry) contribute to problematic recovery after carpal tunnel release, but their relative associations are unclear. QUESTION/PURPOSE: Is problematic initial recovery after carpal tunnel release associated with psychologic distress rather than with disease severity? METHODS: We retrospectively studied 156 patients who underwent in-office carpal tunnel release between November 2017 and February 2020, and we recorded their symptoms of anxiety (Generalized Anxiety Disorder-7 [GAD]) and depression (Patient Health Questionnaire), signs of severe median neuropathy (loss of sensibility, thenar muscle atrophy, and palmar abduction weakness), and problematic recovery. The initial recovery (first 2 weeks) was categorized as problematic if the patient was upset about persistent numbness, experienced unsettling postoperative pain, developed hand stiffness, or experienced wound issues-all of which are routinely recorded in the medical record by the treating surgeon along with signs of severe median neuropathy. Twenty-four percent (38 of 156) of patients had a problematic initial recovery characterized by distress regarding persistent numbness (16% [25 of 156]), unsettling pain (8% [12 of 156]), hand stiffness (5% [8 of 156]), or wound issues (1% [2 of 156]); 6% (9 of 156) of patients had more than one issue. Associations between problematic initial recovery and age, gender, symptoms of anxiety and depression, disease severity, specific exam findings, and insurance were evaluated using t-tests, Mann-Whitney tests, and chi-square tests, with the plan to perform logistic regression if at least two variables had an association with p < 0.10. RESULTS: The only factor associated with problematic initial recovery was greater symptoms of anxiety (median GAD score 1.5 [interquartile range 0 to 7.8] for problematic initial recovery compared with a median score of 0 [IQR 0 to 2] for nonproblematic recovery; p = 0.04), so we did not perform a logistic regression. Physical examination findings consistent with severe median neuropathy were not associated with problematic initial recovery. CONCLUSION: The finding that problematic initial recovery after carpal tunnel release was related to symptoms of anxiety and not to the severity of median neuropathy highlights the need to study the ability of efforts to ameliorate anxiety symptoms before carpal tunnel release as an effective intervention to reduce unplanned visits and additional tests, therapy, and repeat surgery, while improving patient-reported outcomes and experience. LEVEL OF EVIDENCE: Level III, therapeutic study.

RESUMEN

Research literature and community narratives both emphasize the importance of self-determination in the lives of deaf youth. This paper describes the development, initial validation, and potential applications of a translated measure of self-determination for deaf youth, the SDI:SR ASL Translation (SDI:SR ASL). A sample of 3,309 young people who completed the SDI:SR, of whom 392 were deaf, was used in this validation study. Results provide preliminary support for the use of SDI:SR ASL with deaf youth. Findings also indicate that deaf youth who take the SDI:SR ASL score more similarly to youth without disabilities taking the SDI:SR than youth with disabilities. The SDI:SR ASL can be an important tool for researchers and practitioners to better understand self-determination among deaf youth and facilitate continued development of self-determination skills.

RESUMEN

PURPOSE: To describe characteristics and outcomes of primary rhegmatogenous retinal detachment in older adults (age ≥ 80). METHODS: Consecutive patients with rhegmatogenous retinal detachment undergoing pars plana vitrectomy (PPV), scleral buckling (SB), or PPV/SB in the Primary Retinal Detachment Outcomes Study were evaluated. Outcome measures included single surgery anatomic success and visual acuity. RESULTS: Of 2,144 patients included, 125 (6%) were 80 years or older. Compared with younger patients (age 40-79), older adults were more likely to be pseudophakic (P < 0.001), have macula-off detachments (P < 0.001), and have preoperative proliferative vitreoretinopathy (P = 0.02). In older adults, initial surgery was PPV in 73%, PPV/SB in 27%, and primary SB in 0%. Single surgery anatomic success was 78% in older adults compared with 84% in younger patients (P = 0.03). In older adults, single surgery anatomic success was 74% for PPV and 91% for PPV/SB (P = 0.03). The final mean logMAR was lower for older adults (0.79 [20/125] vs. 0.40 [20/40], [P < 0.001]). In older adults, the final mean logMAR for eyes that underwent PPV was 0.88 (20/160) compared with 0.50 (20/63) for PPV/SB (P = 0.03). CONCLUSION: Octogenarians and nonagenarians presented with relatively complex pseudophakic rhegmatogenous retinal detachments. Single surgery anatomic success and visual outcomes were worse compared with younger patients, and PPV/SB had better outcomes compared with PPV alone.

RESUMEN

INTRODUCTION: Rhegmatogenous retinal detachments with inferior retinal breaks are believed to have a higher risk of recurrent rhegmatogenous retinal detachment. This study compared anatomic and visual outcomes between primary pars plana vitrectomy (PPV) and combination PPV with scleral buckle (PPV/SB) for rhegmatogenous retinal detachments with inferior retinal breaks. METHODS: This is an analysis of the Primary Retinal Detachment Outcomes study, a multi-institutional cohort study of consecutive primary rhegmatogenous retinal detachment surgeries from January 1, 2015, through December 31, 2015. The primary outcome was single-surgery success rate. Only eyes with inferior retinal breaks (one break in the detached retina between five and seven o'clock) were included. RESULTS: There were 238 eyes that met the inclusion criteria, 95 (40%) of which underwent primary PPV and 163 (60%) that underwent combined PPV/SB. The single-surgery success rate was 76.8% for PPV and 87.4% for PPV/SB (P = 0.0355). This remained significant on multivariate analysis (P = 0.01). Subgroup analysis showed that a superior single-surgery success rate of PPV/SB was especially noted in phakic eyes (85.2% vs. 68.6%; P = 0.0464). CONCLUSION: Retinal detachment with inferior retinal breaks had a higher single-surgery success rate if treated with PPV/SB compared with PPV alone, particularly in phakic eyes.

RESUMEN

Successful social engagement is one of many important outcomes for deaf youth as they transition from high school to adult life. This study examined the effect of self-advocacy and social/life skill trainings in secondary school settings on social engagement after high school using propensity score modeling and data from the large-scale and nationally representative National Longitudinal Transition Study-2. Analyses focused on three types of post-high school social engagement: frequency of seeing friends, involvement in group activities, and participation in community service. A fourth outcome variable was created to indicate whether the individual was at least minimally engaged. Results found that deaf youth who received self-advocacy training in secondary school were significantly more likely to be at least minimally engaged than those who had not. These findings suggest that self-advocacy training in high school can help protect deaf youth against social isolation in young adulthood.

RESUMEN

PURPOSE: Anatomically similar rhegmatogenous retinal detachments (RRDs) can be treated with scleral buckle (SB), pars plana vitrectomy (PPV), or SB combined with PPV (PPV/SB). This study compares moderately complex phakic primary RRD treated with SB, PPV, or PPV/SB to review anatomic and visual outcomes. DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered on all patients from multiple retina practices in the United States with RRD in 2015 and >90 days of follow-up. The cohort of phakic patients with moderately complex RRD was analyzed. METHODS: A large and detailed database was generated. Eyes with findings that would bias toward PPV (vitreous hemorrhage, dense cataract, proliferative vitreoretinopathy, giant retinal tear, among others) were excluded. Age <40 years (bias toward SB) was excluded. Comparable cases of moderately complex RRD were then chosen naive to surgeon, surgery, and outcome for subgroup analysis. MAIN OUTCOME MEASURES: Single surgery anatomic success (SSAS), defined as retinal attachment with no other RRD surgery within 90 days, is the main outcome measure. Final visual acuity is the secondary outcome measure. Pearson's chi-square and analysis of variance were used to test treatment effect of surgery type on SSAS and vision. RESULTS: Single surgery anatomic success was noted in 155 of 169 SB cases (91.7%), 207 of 249 PPV cases (83.1%), and 271 of 297 PPV/SB cases (91.2%). Scleral buckle and PPV/SB were superior to PPV for SSAS (P = 0.0041). For macula-on or split cases, SB had significantly better visual outcomes than PPV or PPV/SB even after controlling for cataract (cases with minimal cataract at final follow-up or after cataract surgery) (P < 0.001). CONCLUSIONS: For phakic moderately complex primary RRDs in this study of PPV versus SB versus PPV/SB, SB had the best visual outcomes, and PPV had the worst SSAS outcomes.

RESUMEN

PURPOSE: This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB). DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered from patients from multiple retina practices in the United States with RRD in 2015. METHODS: A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days. MAIN OUTCOME MEASURES: Single surgery anatomic success and final Snellen visual acuity (VA). RESULTS: A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805). CONCLUSIONS: In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.

RESUMEN

PURPOSE: To determine factors associated with 360-degree laser retinopexy (360LR) during primary pars plana vitrectomy ± scleral buckle for rhegmatogenous retinal detachment (RRD) and its impact on surgical outcomes. METHODS: This is a multicenter, retrospective, interventional study. Patients undergoing primary pars plana vitrectomy or primary pars plana vitrectomy + scleral buckle for noncomplex primary RRD in 2015 were evaluated. Primary outcomes were single surgery anatomical success (SSAS) and final anatomical success. Secondary outcomes included final logarithm of the minimum angle of resolution visual acuity, epiretinal membrane formation, cystoid macular edema development, and number of subsequent vitrectomies. Multivariate regressions were performed. RESULTS: Two thousand two hundred and forty-eight surgeries by 61 surgeons were included; of which, 516 underwent 360LR. Younger age (P = 0.01), more retinal breaks (P = 0.01), more extensive RRD (P < 0.001), and surgeon ID (P < 0.001) were significantly associated with 360LR. No significant associations between 360LR and single surgery anatomical success (P = 0.44), epiretinal membrane formation (P = 0.14), cystoid macular edema development (P = 0.28), or number of subsequent vitrectomies (P = 0.41) were found. Controlling for case complexity, 360LR was significantly associated with lower final anatomical success (P < 0.001) and worse final logarithm of the minimum angle of resolution visual acuity (P < 0.001). CONCLUSION: Multiple factors influenced whether 360LR was performed during primary pars plana vitrectomy ± scleral buckle for RRD. However, 360LR was not associated with improved surgical outcomes, and in fact, it may be associated with poorer outcomes.

RESUMEN

BACKGROUND: Persistent infection with high-risk types of human papillomavirus (HPV) is the preeminent factor driving the development of cervical cancer. There are large gaps in knowledge about both the role of pregnancy in the natural history of HPV infection and the impact of HPV on pregnancy outcomes. METHODS: This single-site prospective cohort substudy, nested within an international multisite randomized controlled trial, assessed prevalence, incident cases, and persistence of type-specific HPV infection, and the association between persistence of high-risk HPV infection with pregnancy outcomes among HIV-infected pregnant women in Kenya, including HIV transmission to infants. Type-specific HPV was assessed using a line probe assay in pregnancy and again at 3 months after delivery. HIV status of children was determined using polymerase chain reaction at 6 weeks. RESULTS: In total, 84.1% (206/245) of women had a high-risk HPV infection at enrollment. Three quarters (157/206) of these infections persisted postpartum. Persistence of HPV16 and/or HPV18 types was observed in more than half (53.4%; 39/73) of women with this infection at enrollment. Almost two-thirds had an incident high-risk HPV infection postpartum, which was not present in pregnancy (62.5%), most commonly HPV52 (19.0%). After adjustments, no association was detected between persistent high-risk HPV and preterm birth. All mothers of the 7 cases of infant HIV infection had persistent high-risk HPV infection (P = 0.044). CONCLUSIONS: High levels of high-risk HPV infection and type-specific persistence were documented, heightening the urgency of mass role out of HPV vaccination. The association between HPV persistence and HIV transmission is a novel finding, warranting further study.

RESUMEN

The national prevalence of depression and anxiety disorders among deaf adults who use American Sign Language (ASL) remains largely understudied. Data for self-reported depression and anxiety disorder diagnosis (n = 1,704 deaf adults; n = 3,287 hearing adults) as told by their healthcare providers were drawn from HINTS-ASL and HINTS datasets. Chi-square and Poisson regression analysis compared characteristics and predictors for depression or anxiety disorder diagnosis among deaf adults. Rate of diagnosed depression or anxiety disorder was significantly higher (25%) and occurred at earlier age (45 years; SD = 15) for deaf adults compared to hearing adults (22%; mean age = 56; SD = 14). After adjusting for covariates, deaf individuals who were White, younger, female, educated, or single were significantly more likely to self-report a diagnosis of depression/anxiety disorder as told by their healthcare providers. Deaf adults have higher reported rate of diagnosis of depression or anxiety disorder at an earlier onset compared to the general population. Communication access with healthcare providers is essential for accurate diagnosis, treatment, and follow up care.

RESUMEN

Frequent HIV testing among gay, bisexual and other men who have sex with men (GBM) is a strategic priority for HIV prevention in Australia. To overcome barriers to testing in conventional clinical services, Australia recently introduced peer HIV rapid point of care (RPOC) testing services for GBM. This mixed methods evaluation describes client acceptability and HIV prevention benefits of a peer HIV testing model. Most aspects of the service model were overwhelmingly acceptable to clients. Two-thirds of survey participants reported preferring testing with peers rather than doctors or nurses and over half reported learning something new about reducing HIV risk. Focus group findings suggested peer-delivered HIV RPOC testing reduced stigma-related barriers to frequent testing and provided novel opportunities for GBM to openly discuss HIV prevention and sexual practices, enhancing their HIV risk-reduction knowledge. Analysis of survey data suggested knowledge transfer occurred particularly among younger and less gay community-attached GBM.

RESUMEN

Men who have sex with men (MSM) and transgender women (TW) are a priority population for HIV prevention in Myanmar but report sub-optimal HIV testing frequency. Previous studies have shown that peer involvement in HIV testing can normalize stigmatized sexualities and reduce barriers to testing. We explored the acceptability of peer-delivered HIV testing among 425 undiagnosed MSM and TW in Yangon and Mandalay. An overwhelming majority of participants (86%) reported being 'comfortable/very comfortable' with peer-delivered HIV testing. Logistic regression identified reporting sexual identity as Apone [adjusted odds ratio (aOR) 3.8; 95% CI 1.2-11.7], recent HIV testing (aOR 3.1; 95% CI 1.4-6.5), reporting a high likelihood of HIV acquisition (aOR 3.6; 95% CI 1.7-7.6), and reporting ≥ 5 casual partners in the past 3 months (aOR 0.2; 95% CI 0.1-0.6) as associated with peer-delivered HIV testing acceptability. Given ongoing HIV vulnerability among MSM and TW in Myanmar, peer-delivered testing may offer prevention benefits by increasing testing rates and identifying undiagnosed infection earlier.

RESUMEN

Deaf people face significant barriers with accessing health information, health care services, and communication with their health care provider and as a result, show poorer health outcomes compared to the general population. Studies on the general population found that those who use social network sites (SNS) for health-related activities were more likely to communicate with their health care provider via the Internet or email. For deaf individuals who use American Sign Language (ASL), using eHealth platforms to communicate with health care providers has the potential to navigate around communication barriers and create greater opportunity to discuss screening and treatment plans. Using national data from the HINTS-ASL survey, we explored whether engagement in social eHealth activities on SNS is linked to electronic communication with health care providers after controlling for deaf patient characteristics. Our sample for this study consisted of 515 deaf participants who reported using (social media/SNS) to read and share health information. Controlling for sociodemographic variables, participants who engaged in social eHealth activity were threefold more likely to communicate with their healthcare provider electronically. Using eHealth platforms for social health engagement demonstrates potential to reduce health inequality among deaf people.

RESUMEN

This study investigates the relationship between critical health literacy (CHL) and discussion of health information among college deaf students who use American Sign Language. CHL is crucial in making appropriate health-related decisions for oneself and aiding others in making good health-choices. Research on general youth population shows that frequent health-related discussions with both friends and family is associated with higher health literacy. However, for our sample of deaf college-aged students who might have had less access to communication at home, we hypothesize that health-related discussions with same-age peers may be more important for critical health literacy. We asked two questions to assess the frequency of health-related discussions with friends and families: "How often do you discuss health-related information with your friends" and "How often do you discuss your family medical history with your family?". Participants rated their experience on a scale from 1-5 (1=never, 5=always). To assess CHL, 38 deaf and 38 hearing participants were shown a short scenario that showed a woman confiding in her friend after finding a lump in her breast. Participants were then asked what the friend should say. Responses were scored by a team of 3 raters using a CHL rubric. As predicted, results showed a strong relationship between discussion of health-related information with friends and CHL in both deaf and hearing samples. Discussion with family was linked to CHL only for hearing participants, but not deaf participants in our study. These findings underscore the importance of socializing with health-literate, accessible peers to improve the health literacy and health outcomes of all deaf people.

RESUMEN

BACKGROUND: Papua New Guinea (PNG) has among the highest estimated burdens of cervical cancer globally but currently has no national cervical screening program. Visual inspection of the cervix with acetic acid (VIA) is a low-cost screening strategy endorsed by the World Health Organization that has been adopted in many low-resource settings but not previously evaluated in PNG. AIM: To evaluate the association between VIA examination findings and high-risk HPV (hrHPV) infection; and the impact of concomitant genital Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis on the interpretation of VIA findings. METHODS: A prospective clinical cohort study among women aged 30-59 years attending Well Woman Clinics in PNG. Main outcome measures were VIA examination findings and laboratory-confirmed hrHPV, C. trachomatis, N. gonorrhoeae and T. vaginalis. RESULTS: A total of 614 women were enrolled, of whom 87.5% (537/614) underwent VIA, and 12.5% (77/614) did not due to pre-existing cervicitis or inability to visualise the transformation zone. Among the 537 women who underwent VIA, 21.6% were VIA positive, 63.7% VIA negative, and 14.7% had indeterminate findings. The prevalence of hrHPV infection (n = 614) was 14.7%; C. trachomatis, 7.5%; N. gonorrhoeae, 8.0%; and T. vaginalis, 15.0%. VIA positive women were more likely to have HPV16 (odds ratio: 5.0; 95%CI: 1.6-15.6; P = 0.006) but there was no association between HPV18/45, all hrHPV types (combined), C. trachomatis, N. gonorrhoeae or T. vaginalis. CONCLUSIONS: VIA positivity was associated with HPV16, but not with other hrHPV infections, nor with genital C. trachomatis, N. gonorrhoeae or T. vaginalis in this setting.
