“…But even for the investigation of malignant and pre-malignant lesions, new screening tools based on self-sampling coupled with molecular tests for HPV DNA amplification and/or rapid tests for detection of highrisk HPV oncoproteins have been studied, exhibiting promising results [18]. The reasons most often reported by women who preferred self-collection were "privacy" and "comfort", which is in agreement with other studies, since the main barriers conveyed to IST screening include shame (especially with male professionals), fear of pain, discomfort with pelvic examination, invasiveness of professional collection, distrust of confidentiality, and long waiting times in clinics [19][20][21]. On the other hand, some women indicated concern about the safety of the method (that is, it may be that they are not doing the collection correctly, which could generate a false negative result) considering the collection by a professional to be safer.…”

Introduction: The challenges related to the diagnosis of sexually transmitted infections present more complex factors in remote and hard-to-reach areas. The use of self-collection devices that facilitate the obtaining of a biological sample with high quality for sensitive molecular tests have been examined. This study aimed to evaluate the performance and acceptance of the Evalyn® Brush (Rovers® Medical Devices) for detection of T. vaginalis among women living in the riverside communities of Amazonas, Brazil. Methodology: The study included 300 riverside women. They received instructions for self-collection, carried out the task, and then answered a questionnaire on the use of the device. T. vaginalis was detected by Polymerase Chain Reaction, using primers TVK3/TVK7. Results: The mean age of the women was 35.8 years, and most of them presented low schooling, low income, agricultural activity and lived in a marital union. All samples were positive for human genomic DNA (100%) and the prevalence of T. vaginalis infection was 5.6% (n = 17). Of the 300 women, 293 (97.7%) indicated that they liked the use of the device, 287 (95.7%) reported having had no difficulty in handling it, 265 (88.3%) did not feel any type of discomfort and 228 (76%) said they preferred the self-collection to the collection made by the professional, mainly due to privacy and comfort. Conclusions: The Evalyn® Brush proved reliable as a device for the collection of biological samples for molecular analysis and was well-accepted by women. Its use can be indicated in remote and hard to reach places.

Objectives Annual screening for gonorrhea (NG) and chlamydia (CT) is recommended for all sexually-active persons living with HIV (PLWH) but is poorly implemented. Studies demonstrating no increases in NG and/or CT (NG/CT) case detection in clinics that successfully expanded NG/CT screening raise questions about this broad screening approach. We evaluated NG/CT case detection in the HIV Research Network during 2004–2014, a period of expanding testing. Methods We analyzed linear time trends in annual testing (patients tested divided by all patients in care), test positivity (patients positive divided by all tested), and case detection (the number of patients with a positive result divided by all patients in care) using multivariate repeated measures logistic regression. We determined trends overall and stratified by men who have sex with men (MSM), men who have sex exclusively with women (MSW), and women. Results Among 15,614 patients (50% MSM, 26% MSW, 24% women), annual NG/CT testing increased from 22% in 2004 to 60% in 2014 (adjusted odds ratio [AOR] per year 1.22 [1.21, 1.22]). Despite the increase in testing, test positivity also increased (AOR per year 1.10 [1.07, 1.12]), and overall case detection increased from 0.8% in 2004 to 3.9% in 2014 (AOR per year 1.20 [1.17, 1.22]). Case detection was highest among MSM but increased over time among all three groups. Conclusions NG/CT case detection increased as testing expanded in the population. This supports a broad approach to NG/CT screening among PLWH in order to decrease transmission and complications of NG/CT and of HIV.

“…Es conocido que el diagnóstico de laboratorio es limitado en poblaciones urbano-rurales de países de bajos y medianos recursos. Una estrategia para masificar el tamizaje de estas infecciones, es el uso de la autotoma (AC) de muestras para el diagnóstico de laboratorio que se han utilizado en centros de atención (6) , clínicas (7) , en casa (8) o en carpas de campaña (9) . La técnica de autotoma para la identificación de ITS es aceptable y preferida en comparación a la colección estándar realizada por un personal de salud, principalmente en poblaciones urbanas pero también en poblaciones rurales (10,11) .…”

Con el objetivo de evaluar la concordancia entre la autotoma de muestras vaginales y la toma estándar de muestras endocervicales para la identificación de Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis y Candida spp. realizadas por el personal de salud en mujeres de un área urbano-rural del Perú, se realizó un estudio prospectivo y transversal en 206 mujeres en edad fértil, identificamos algunas infecciones de transmisión sexual como Chlamydia trachomatis o Trichomonas vaginalis en 9 mujeres (4,4%). Obtuvimos una concordancia casi perfecta en la identificación de Candida spp. (k=0,97), Chlamydia trachomatis (k=0,92) y Trichomonas vaginalis por microscopía (k=1,00), y considerable para la identificación de Trichomonas vaginalis por cultivo (k=0,66). La técnica de la autotoma de muestras vaginales podría ser usada para la identificación de algunas infecciones de transmisión sexual en población urbano-rural.
