Health Outcomes at 1 Year After Thermal Ablation for Cervical Precancer Among Human Papillomavirus- and Visual Inspection With Acetic Acid-Positive Women in Honduras.

Purpose: This study aims to assess the detection of cervical intraepithelial lesions grades 2 and 3 (CIN2-3) at 1 year after treatment with thermal ablation among human papillomavirus (HPV)-positive and visual inspection with acetic acid (VIA)-positive women.

Methods: All women screened and triaged for cervical cancer at four government health facilities in Honduras who were eligible for ablative treatment were enrolled and treated with thermal ablation. Women with confirmed CIN2-3 and a subset of women with CIN1/normal diagnoses at baseline were evaluated at 12 months.

Age patterns of human papillomavirus infection as primary screening test for cervical cancer and subsequent triage with visual inspection in Honduras.

Objective: To evaluate age patterns in human papillomavi-rus (HPV) prevalence and visual inspection with acetic acid (VIA) positivity among women participating in cervical cancerscreening in Honduras.

Materials And Methods: Data on the HPV status (careHPV) and subsequent VIA in HPV-positivewomen were retrieved from three provinces within the PublicHealth Sector.

Results: Between 2015 and 2018, 60 883 women aged 15-85 years were screened.

Recall Efforts Successfully Increase Follow-Up for Cervical Cancer Screening Among Women With Human Papillomavirus in Honduras.

Scaling up coverage of routine cervical screening in low-resource settings must be accompanied by efforts to retain women throughout the screening cascade and continuum of care, including adequate follow-up of abnormal results. The Scale-Up Project implemented human papillomavirus (HPV) testing for cervical cancer screening within public-sector health facilities in Honduras between 2015 and 2019. Women who were HPV-positive but did not have visually confirmed cervical lesions upon visual inspection with acetic acid (VIA-negative) were instructed to return to the health center after 1 year for repeat HPV testing.

Introduction of HPV testing for cervical cancer screening in Central America: The Scale-Up project.

The Scale-Up project introduced vaginal self-sampling and low-cost human papillomavirus (HPV) testing as the primary approach for cervical cancer screening in selected public health centers in Guatemala, Honduras, and Nicaragua. We evaluate the country-specific accomplishments in screening: target-coverage, triage, and treatment. Between 2015 and 2018, cervical cancer screening was offered to women at least 30 years of age.

Acceptability and safety of thermal ablation for the treatment of precancerous cervical lesions in Honduras.

Objective: To evaluate the acceptability and safety of thermal ablation (TA) for the treatment of precancerous cervical lesions in women in Honduras.

Methods: Human papillomavirus (HPV) and visual inspection with acetic acid (VIA) screen-positive eligible women received TA. After treatment, women rated the level of pain experienced during treatment using the Wong-Baker FACES® pain-rating scale from 0 to 10.

Evaluation of in vivo solid phase microextraction for minimally invasive analysis of nonvolatile phytochemicals in Amazonian plants.

Introduction: Although solid phase microextraction (SPME) has been used extensively for fingerprinting volatile compounds emitted by plants, there are very few such reports for direct insertion SPME. In this research, direct contact of SPME probes with the interstitial fluid of plants was investigated as a method for phytochemical analysis.

Objective: Medicinal plants from the Amazon have been the source of numerous drugs used in western medicine.

Chemoenzymatic synthesis of carbohydrates as antidiabetic and anticancer drugs.

Different chemoenzymatic strategies for the preparation of carbohydrates and analogues possessing antidiabetic or anticancer activity are summarized. In this sense, some examples illustrating the use of enzymes such as aldolases, lipases or glycosidases (in some cases improved by genetic engineering techniques) are presented, showing the advantages of the implementation of chemoenzymatic protocols, which combine the flexibility of chemical synthesis with the efficiency, selectivity and sustainability of biotransformations to obtain diverse complex carbohydrates, glycoconjugates and glycomimetics.

Preventing peridural fibrosis with nonsteroidal anti-inflammatory drugs.

Peridural fibrosis is one of the more frequent complications of lumbar surgery. Nonsteroidal anti-inflammatory drugs inhibit the inflammatory and fibroblastic response. We performed lumbar laminectomies in 24 rabbits, divided into two groups.

Plasma zinc levels inversely correlate with vascular cell adhesion molecule-1 concentration in children with sickle cell disease.

Zinc deficiency has been implicated in impaired cell-mediated immunity of children with sickle cell disease (SCD). However, its influence on the expression of vascular cell-adhesion molecule-1 (VCAM-1) on endothelial cells, a protein involved in vasoocclusion, has not been previously investigated. We therefore measured (soluble) sVCAM-1 and zinc in 76 SCD children and 96 non-SCD children, mean age 7.

New oleanan-type triterpene and cincholic acid glycosides from Peruvian "Uña de Gato" (Uncaria tomentosa).

A new oleanan-type triterpene and three new cincholic acid glycosides were isolated from Peruvian "Una de Gato" (Cat's claw, plant of origin: Uncaria tomentosa), a traditional herbal medicine in Peru. Their structures were determined by spectroscopic analysis.

Two new nor-triterpene glycosides from peruvian "Uña de Gato" (Uncaria tomentosa).

Two new 27-nor-triterpene glycosides, tomentosides A (1) and B (2), were isolated from Peruvian "Uña de Gato" (cat's claw, plant of origin: Uncaria tomentosa), a traditional herbal medicine in Peru. Their structures were determined by spectroscopic analysis and chemical interconversions. This is the first report of naturally occurring pyroquinovic acid glycosides.

Sangre de grado Croton palanostigma induces apoptosis in human gastrointestinal cancer cells.

Sangre de grado is an ethnomedicinal red tree sap obtained from Croton spp. that is used to treat gastrointestinal ulcers, cancer and to promote wound healing. To evaluate the potential role of sangre de grado (SdG) in cancer we examined its effects on human cancer cells, AGS (stomach), HT29 and T84 (colon).
