- Abstract
Introduction: Sexually transmitted infections (STIs) cause considerable morbidity worldwide and, depending on the specific pathogen, may lead to serious complications in the female reproductive tract. Incarcerated women are particularly vulnerable to health problems with a disproportionate high rate of STIs, including infections with human papillomavirus (HPV)., Methods: Here, cervical swab samples collected from 299 women (18 to 64 years) living in one of the women's prisons of São Paulo, Brazil were submitted for liquid-based cytology to determine the prevalence of precancerous lesions. Furthermore, direct detection of 30 genital HPV genotypes (18 high-risk and 12 low-risk types) and 11 additional STIs ( Chlamydia trachomatis , Neisseria gonorrhoeae , Herpes simplex virus 1 and 2, Haemophilus ducreyi , Mycoplasma genitalium and hominis , Treponema pallidum , Trichomonas vaginalis , Ureaplasma parvum and urealyticum ) were performed by molecular typing using two PCR-based DNA microarray systems, i.e., EUROArray HPV and EUROArray STI (EUROIMMUN), respectively., Results: The overall prevalence of cytological abnormalities was 5.8%, including five women with low-grade and five women with high-grade squamous intraepithelial lesions. The overall prevalence of HPV was 62.2, and 87.1% of the HPV-positive women were infected with oncogenic high-risk (HR) HPV types. HPV types 16 (24.1%), 33 and 52 (both 10.4%) were the most frequently detected. The prevalence of the other STIs was 72.8%. Up to four different pathogens were found in the infected women, the most frequent being Ureaplasma parvum (45.3%), Mycoplasma hominis (36.2%) and Trichomonas vaginalis (24.8%)., Conclusion: The high number of HR-HPV infections and other STIs described here highlights the fact that the Brazilian female prison population requires more attention in the country's health policies. The implementation of screening programs and treatment measures might contribute to a decrease in the incidence of STIs and cervical cancer in this vulnerable population. However, for such measures to be effective, further studies are needed to investigate the best practice to get more women to engage in in-prison prevention programs, e.g., through offering further sexual health education and self-sampling., Competing Interests: AL, AS, MiS, MK, and MC are employees of EUROIMMUN. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Zonta, Liljander, Roque, Schillert, Kai, dos Santo, de Freitas, Soane, Cavalar, Janaudis and Shio.)

- Abstract
Duchenne muscular dystrophy (DMD) is a rare genetic disorder in which patients progressive muscle deterioration and low life expectancy. Since DMD has no cure, treatment slows the deterioration process using corticosteroids and other medications, including oral bisphosphonates (BP). These drugs can lead to toxicities in both soft and hard tissues. The objective of this study was to present cytological changes in DMD patients, comparing to young, healthy individuals. Cytological smears were obtained from buccal mucosa from nine DMD patients and five healthy patients. The Papanicolaou technique was used to stain the slides. Images were captured using a photomicroscope, and 50 clearly defined cells were selected. The size and ratio between the nucleus and cytoplasmic areas (NA/CA) diameter were measured using a computer program. All the DMD patients presented a statistical difference (p < 0.0001) in the size of the cytoplasm (0.60 ± 0.33 μm) and the NA/CA ratio (0.17 ± 0.07 μm) was seen when compared to the control group (cytoplasm 0.60 ± 0.15 µm and nucleus 0.14 ± 0.05 µm). Furthermore, in one DMD in use of BP who presented Medication-Related Osteonecrosis of the Jaw (MRONJ), presented higher differences in the cytoplasmic (1.20 ± 0.65 µm) and nuclear (0.20 ± 0.12 µm) sizes (p < 0.0001) compared with all others DMD patients. These results suggest that the drugs used or the systemic condition of individuals with DMD may contribute to these changes., (© 2022.

- Abstract
Background: Chlamydia trachomatis (Ct) is not a disease subject to mandatory reporting in Brazil, and the prevalence rate of this genital infection varies according to the region in which studies are conducted, as well as by the detection technique employed. Ct has been associated with persistence of Human papillomavirus (HPV) infection and the facilitation of cervical carcinoma development. We evaluated the Chlamydia trachomatis infection and its association with cytology, p16/Ki-67 dual-stained cytology and cervical intraepithelial lesions status in a screening cohort in Brazil., Methods: This was a cross-sectional study of 1481 cervical samples from asymptomatic women aged 18 to 64. Samples were collected for liquid-based cytology and Ct detection by polymerase chain reaction. p16/Ki-67 double staining was performed on samples with abnormal cytology. Statistical analysis was by chi-square and likelihood-ratio tests. Odds ratio (OR) and 95% confidence intervals (95% CI) were determined., Results: The frequency of Ct was 15.6% and its presence was not associated with detection of p16/Ki-67 [OR = 1.35 (0.5-3.4)]. There was also no association between abnormal cervical cytology and Ct -positivity [OR = 1.21 (0.46-3.2)]. Associations were observed between p16/Ki-67 and high-grade lesions detected by cytology and in biopsies [OR = 3.55 (1.50-8.42) and OR = 19.00 (0.6-7.2), respectively]., Conclusions: The asymptomatic women in our study had a high frequency of Ct infection but this was not associated with p16/Ki-67 detection in samples with abnormal cytology. The expression of p16/Ki-67 was highest in women with high-grade CIN ( p = 0.003).
