Establishing an autogenous vascular access program in a Guatemalan comprehensive pediatric nephrology center.

Background: The Guatemalan Foundation for Children with Kidney Diseases collaborated with Bridge of Life, a not-for-profit charitable organization, to establish a vascular access program. We reviewed our experience with graded surgical responsibility and structured didactic training, creating arteriovenous fistulas (AVF) for Guatemalan children.

Methods: Pediatric vascular access missions were completed from 2015 to 2023 and analyzed retrospectively.

Epidemiology of HPV-associated cancers past, present and future: towards prevention and elimination.

Cervical cancer is the first cancer deemed amenable to elimination through prevention, and thus lessons from the epidemiology and prevention of this cancer type can provide information on strategies to manage other cancers. Infection with the human papillomavirus (HPV) causes virtually all cervical cancers, and an important proportion of oropharyngeal, anal and genital cancers. Whereas 20th century prevention efforts were dominated by cytology-based screening, the present and future of HPV-associated cancer prevention relies mostly on HPV vaccination and molecular screening tests.

The Impact of a Computer-Based Interactive Informed Consent for Surgery on Decision Conflict.

Purpose: Informed consent for surgery can address the legal aspects of care while also being simple, informative, and empathic. We developed interactive informed consents and compared them with standard printed informed consents asking: (1) are there any factors associated with lower decision conflict or greater patient-rated clinician empathy including consent format? (2) Are there any factors associated with rating the consent process as informative, comfortable, and satisfying including consent format?

Methods: Ninety-four adult patients accepted an offer of surgery from one of three hand surgeons to address one of six common hand surgery diagnoses: carpal tunnel release, cubital tunnel release, trigger finger release, plate and screw fixation of a distal radius fracture, removal of a benign mass, including a ganglion cyst, and Dupuytren contracture release. Fifty-three patients were randomized to complete an interactive consent, and 41, a standard written consent.

Baseline extracellular vesicle miRNA-30c and autophagic CTCs predict chemoradiotherapy resistance and outcomes in patients with lung cancer.

Concurrent chemoradiotherapy (cCRT) is the mainstay of treatment for patients diagnosed with locally advanced non-small cell lung cancer (NSCLC). One significant challenge in the effectiveness of this therapy is the potential development of resistance mechanisms, where autophagy up-regulation has been proposed as a key contributing factor. However, there is a lack of reliable biomarkers to predict outcomes on these patients.

Factors Associated With Concerns the Day After Office Hand Surgery.

Purpose: Pain after minor hand surgery can be misinterpreted as a problem. The sense that something may be wrong intensifies the pain. Some surgeons anticipate these feelings and call patients the evening or day after surgery to guide them through the recovery process.

Intra-nucleus mosaic pattern (InMop) and whole-cell Haralick combined-descriptor for identifying and characterizing acute leukemia blasts on single cell peripheral blood images.

Acute leukemia is usually diagnosed when a test of peripheral blood shows at least 20% of abnormal immature cells (blasts), a figure even lower in case of recurrent cytogenetic abnormalities. Blast identification is crucial for white blood cell (WBC) counting, which depends on both identifying the cell type and characterizing the cellular morphology, processes susceptible of inter- and intraobserver variability. The present work introduces an image combined-descriptor to detect blasts and determine their probable lineage.

Preference heterogeneity in health valuation: a latent class analysis of the Peru EQ-5D-5L values.

Background: Preference heterogeneity in health valuation has become a topic of greater discussion among health technology assessment agencies. To better understand heterogeneity within a national population, valuation studies may identify latent groups that place different absolute and relative importance (i.e.

Cost-effectiveness of human papillomavirus vaccination in girls living in Latin American countries: A systematic review and meta-analysis.

Background: Cervical cancer is a major public health problem in Latin America. Cost-effectiveness studies help stakeholders with decisions regarding human papillomavirus (HPV) vaccination programs, one of the main prevention measures. Our objective was to synthesize the results of cost-effectiveness studies of HPV vaccination in girls, to understand factors influencing cost-effectiveness in the region.

Manufacturing and Characterization of Environmentally Friendly Wood Plastic Composites Using Pinecone as a Filler into a Bio-Based High-Density Polyethylene Matrix.

The use of wood plastic composites (WPC) is growing very rapidly in recent years, in addition, the use of plastics of renewable origin is increasingly implemented because it allows to reduce the carbon footprint. In this context, this work reports on the development of composites of bio-based high density polyethylene (BioHDPE) with different contents of pinecone (5, 10, and 30 wt.%).

Comparison of EQ-5D Values Sets Among South American Countries.

Objective: Social health preference sets are necessary for conducting health economic evaluations. Values from other countries are often used when local sets are not available, which may alter the results. We aimed to evaluate the degree of variability of currently available country-specific value sets of the EuroQol EQ-5D instrument from South American countries (SAC).

Peruvian Valuation of the EQ-5D-5L: A Direct Comparison of Time Trade-Off and Discrete Choice Experiments.

Objectives: (1) To produce Peruvian general population EQ-5D-5L value sets on a quality-adjusted life-year scale, (2) to investigate the feasibility of a "Lite" protocol less reliant on the composite time trade-off (cTTO), and (3) to compare cTTO and discrete choice experiment (DCE) value sets.

Methods: A random sample of adults (N = 1000) in Lima, Arequipa, and Iquitos did a home interview; 300 were randomly selected to complete 11 cTTOs first. All respondents completed a DCE, including 10 latent-scale pairs (A/B) with 5 EQ-5D-5L attributes, and 12 matched pairs (A/B and B/C) with 5 EQ-5D-5L and one lifespan attributes.

Chemotherapy and radiation therapy elicits tumor specific T cell responses in a breast cancer patient.

Background: Experimental evidence and clinical studies in breast cancer suggest that some anti-tumor therapy regimens generate stimulation of the immune system that accounts for tumor clinical responses, however, demonstration of the immunostimulatory power of these therapies on cancer patients continues to be a formidable challenge. Here we present experimental evidence from a breast cancer patient with complete clinical response after 7 years, associated with responsiveness of tumor specific T cells.

Methods: T cells were obtained before and after anti-tumor therapy from peripheral blood of a 63-years old woman diagnosed with ductal breast cancer (HER2/neu+++, ER-, PR-, HLA-A*02:01) treated with surgery, followed by paclitaxel, trastuzumab (suspended due to cardiac toxicity), and radiotherapy.
