Objective: To determine the prevalence of genital infections (GIs), including sexual transmitted STIs: Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Trichomonas vaginalis, and opportunistic pathogens that generally do not cause STIs, non-classic STI: Ureaplasma urealyticum, Ureaplasma parvum and Mycoplasma hominis, in women with high-risk oncogenic human papillomavirus (hr-HPV) infection and their association with cervical lesions.
Methods: A cross-sectional study was carried out including 231 hr-HPV positive women. Of these, 46 has histologically confirmed cervical intraepithelial neoplasia 3 (CIN3) or more (including CIN3 and cervical cancer lesions-CIN3+).
Unlabelled: Aging is associated with physiological, economic, and psychological changes that can compromise nutritional and functional status.
Aim: To determine the nutritional status of institutionalized older people living in a long-term nursing home "Fundación las Rosas" (FLR), the largest long-stay establishment in Chile, in 2019, and its relationship with functionality.
Methods: Descriptive study of analysis of secondary data in 1646 older adults institutionalized in FLR (60% women).
Background: The constant increase of factors associated with the presence of resistant strains, makes empirical antibiotic selection a challenge in patients hospitalized for community-acquired urinary tract infection.
Aim: We characterized the bacteria and their antimicrobial susceptibility pattern in cultures obtained from adult patients that needed hospitalization for this disease in two tertiary hospitals in Santiago, Chile.
Methods: We conducted a prospective cross-sectional study in adults hospitalized for community-acquired urinary tract infection between 2017 and 2022.
Vascular, Soft Tissue, and Musculoskeletal Imaging in Systemic Sclerosis.

Article Synopsis
- - This review discusses how different imaging techniques help assess vascular and musculoskeletal issues in Systemic Sclerosis (SSc) using methods like thermography, ultrasound, and MRI.
- - Various imaging methods provide insight into conditions associated with SSc, such as Raynaud phenomenon, digital ulcers, and hand contractures.
- - The study highlights that while each imaging technique has its strengths and weaknesses, a combination of methods is essential for an accurate and thorough evaluation of SSc-related complications.
Article Synopsis
- The study investigates how polychlorinated biphenyls (PCBs) affect the brains of female mice, focusing on neurotoxic effects and gene expression changes related to neurodevelopmental and neurodegenerative diseases.
- Exposure to a PCB mixture led to distinct changes in brain pathways, such as activating oxidative phosphorylation and suppressing axon guidance in the prefrontal cortex, while not affecting the striatal metabolome.
- The research highlights the complex interactions between individual PCBs and gene expression, emphasizing the need for further exploration of how specific PCBs impact health outcomes.
