Unveiling Melanoma: A Deep Dive into Disparities at a Latin-American Cancer Institute.

INTRODUCTION: The worldwide incidence of melanoma has increased in the last 40 years. Our aim was to describe the clinic-pathological characteristics and outcomes of three cohorts of patients diagnosed with melanoma in a Latin-American cancer institute during the last 20 years. METHODS: We evaluated three retrospective patient cohorts diagnosed with melanoma at Instituto Nacional de Enfermedades Neoplasicas (INEN), a public hospital in Lima, Peru, for the years 2005-2006, 2010-2011, and 2017-2018. Survival rate differences were assessed using the Log-rank test. RESULTS: Overall, 584 patients were included (only trunk and extremities); 51% were male, the mean age was 61 (3-97) years, and 48% of patients resided in rural areas. The mean time to diagnosis was 22.6 months, and the mean Breslow thickness was 7.4 mm (T4). Lower extremity was the most common location (72%). A majority of the patients (55%) had metastases at the time of presentation, with 36% in stage III and 19% in stage IV. Cohorts were distributed as 2005-2006 (n = 171), 2010-2011 (n = 223), and 2017-2018 (n = 190). No immunotherapy was used. Cohort C exhibited the most significant increase in stage IV diagnoses (12.3%, 15.7%, 28.4%, respectively; p < 0.01). The median overall survival rates at the three-year follow-up demonstrated a decline over the years for stages II (97%, 98%, 57%, respectively; p < 0.05) and III (66%, 77%, 37%; p < 0.01). CONCLUSIONS: There has been a worsening in the incidence of late-stage metastatic melanoma in Peru throughout the years, coupled with a significant decline in overall survival rates. This is underscored by the fact that half of the population lives in regions devoid of oncological access.

Core needle biopsy of breast tumours: comparison of diagnostic performance between surgery and radiology services at a national cancer centre in Latin America.

Introduction: Breast pathology is a very common reason for medical attention. Tissue diagnosis is usually obtained with core needle biopsy which could be performed by breast surgeons or interventional radiologists. Our aim was to assess the comparison of diagnostic performance between the two services. Methods: A retrospective, descriptive and cross-sectional study was carried out on patients who had breast pathology at Instituto Nacional de Enfermedades Neoplasicas in 2019. Descriptive analyses, sensitivity and specificity were calculated using the R program version 4.2.3. Results: From 1,082 patients with breast tumours who underwent core needle biopsy (CNB) during 2019, 782 cases were included. Breast surgeons performed 462 CNBs and radiologists performed 320 CNBs. The 87.5% were palpable tumours and 525 breast carcinomas were identified in the final pathology. The diagnostic performance showed that the sensitivity and specificity were greater than 95% and 98%, respectively. The waiting time in both showed that >95% underwent a CNB before 2 months. The breast surgery service performed the majority of the biopsies in less than 1 week since the indication of the execution of the CNB compared to the radiology service (90% versus 36%). Conclusion: Both hospital services, breast surgery and radiology, are efficient in determining an accurate diagnosis using CNB. However, the breast surgery service performs CNB in a shorter time interval. Breast surgical oncologists are encouraged to perform CNB if there are understaffed radiology services to expedite the diagnosis and treatment of breast cancer patients.

[Core competencies in public health: a regional framework for the Americas]. / Competencias esenciales en salud pública: un marco regional para las Américas.

The response is described to the 2010 call from the Pan American Health Organization to develop a Regional Framework on Core Competencies in Public Health, with a view to supporting the efforts of the countries in the Americas to build public health systems capacity as a strategy for optimal performance of the Essential Public Health Functions. The methodological process for the response was divided into four phases. In the first, a team of experts was convened who defined the methodology to be used during a workshop at the National Institute of Public Health of Mexico in 2010. The second phase involved formation of the working groups, using two criteria: experience and multidisciplinary membership, which resulted in a regional team with 225 members from 12 countries. This team prepared an initial proposal with 88 competencies. In the third phase, the competencies were cross-validated and their number reduced to 64. During the fourth phase, which included two workshops, in March 2011 (Medellín, Colombia) and June 2011 (Lima, Peru), discussions centered on analyzing the association between the results and the methodology.

Optimised Sunflower Oil Content for Encapsulation by Vibrating Technology as a Rejuvenating Solution for Asphalt Self-Healing.

This study aimed to determine an optimal dosage of sunflower oil (i.e., Virgin Cooking Oil, VCO) as a rejuvenator for asphalt self-healing purposes, evaluating its effect on the chemical (carbonyl, and sulfoxide functional groups), physical (penetration, softening point, and viscosity), and rheological (dynamic shear modulus, and phase angle) properties of long-term aged (LTA) bitumen. Five concentrations of sunflower oil (VCO) were used: 1%, 2%, 3%, 4%, and 5% vol. of LTA bitumen. VCO was encapsulated in alginate biopolymer under vibrating jet technology using three biopolymer:oil (B:O) mass ratios: 1:1, 1:5, and 1:9. The physical, thermal, and mechanical properties of the capsules were studied, as well as their effect on the physical properties of dense asphalt mixtures. The main results showed that an optimal VCO content of 4% vol. restored the chemical, physical, and rheological properties of LTA bitumen to a short-term ageing (STA) level. VCO capsules with B:O ratios of 1:5 presented good thermal and mechanical stability, with high encapsulation efficiency. Depending on the B:O ratio, the VCO capsule dosage to rejuvenate LTA bitumen and asphalt mixtures varied between 5.03-15.3% wt. and 0.24-0.74% wt., respectively. Finally, the capsule morphology significantly influenced the bulk density of the asphalt mixtures.

Assessing the impact of palliative care admission of end-of-life cancer adults.

Background: There is evidence that early admission to the palliative care (PC) program in adult cancer patients improves symptoms management, reduces unplanned hospital admissions, minimizes aggressive cancer treatments, and enables patients to make decisions about their end-of-life (EOL) care. Objectives: This retrospective cohort study aimed to determine whether late admission to a PC program is associated with aggressive treatment at the EOL in adult patients with oncological diseases from their admission until death. Design/Methods: The study evaluated the aggressiveness in EOL management in patients with advanced stage oncological diseases who died between 2017 and 2019. The study population was divided into two groups based on the time of admission to the PC program. Aggressiveness at the EOL was measured using five criteria: treatment, hospital admission and duration, emergency department care, and/or intensive care unit utilization. Results: The study found a significant difference in the rate of aggressive EOL treatments between late admission to PC care and early admission [adjusted EOL 79.6% versus 70.4%; relative risk (RR): 1.98, 90% CI: 1.08-3.59, p: 0.061]; In the analysis of secondary variables, a significant association was observed between early admission to PC and the suspension of active treatments at the EOL, leading to a decrease in aggressiveness (77% versus 55.8%; RR: 1.38, 95% CI: 1.14-1.67, p: 0.004). Conclusion: Our findings suggest that early referral to PC services is associated with less aggressive treatment at the EOL, including suspension of active treatments.

Promoter hypermethylation of RARB and GSTP1 genes in plasma cell-free DNA as breast cancer biomarkers in Peruvian women.

BACKGROUND: Promoter hypermethylation is one of the enabling mechanisms of hallmarks of cancer. Tumor suppressor genes like RARB and GSTP1 have been reported as hypermethylated in breast cancer tumors compared with normal tissues in several populations. This case-control study aimed to determine the association between the promoter methylation ratio (PMR) of RARB and GSTP1 genes (separately and as a group) with breast cancer and its clinical-pathological variables in Peruvian patients, using a liquid biopsy approach. METHODS: A total of 58 breast cancer patients and 58 healthy controls, matched by age, participated in the study. We exacted cell-free DNA (cfDNA) from blood plasma and converted it by bisulfite salts. Methylight PCR was performed to obtain the PMR value of the studied genes. We determined the association between PMR and breast cancer, in addition to other clinicopathological variables. The sensitivity and specificity of the PMR of these genes were obtained. RESULTS: A significant association was not found between breast cancer and the RARB PMR (OR = 1.90; 95% CI [0.62-6.18]; p = 0.210) or the GSTP1 PMR (OR = 6.57; 95% CI [0.75-307.66]; p = 0.114). The combination of the RARB + GSTP1 PMR was associated with breast cancer (OR = 2.81; 95% CI [1.02-8.22]; p = 0.026), controls under 50 years old (p = 0.048), patients older than 50 (p = 0.007), and postmenopausal (p = 0.034). The PMR of both genes showed a specificity of 86.21% and a sensitivity of 31.03%. CONCLUSION: Promoter hypermethylation of RARB + GSTP1 genes is associated with breast cancer, older age, and postmenopausal Peruvian patients. The methylated promoter of the RARB + GSTP1 genes needs further validation to be used as a biomarker for liquid biopsy and as a recommendation criterion for additional tests in asymptomatic women younger than 50 years.

Biopolymeric Capsules Containing Different Oils as Rejuvenating Agents for Asphalt Self-Healing: A Novel Multivariate Approach.

This study evaluated the effect of two encapsulation methods (i.e., dropping funnel and syringe pump), two concentrations of the alginate-based encapsulating material (2%, and 3%), and three oils as bitumen rejuvenators (virgin sunflower oil, waste cooking oil, and virgin engine oil) on the morphological, physical, chemical, thermal, and mechanical properties of encapsulated rejuvenators for asphalt self-healing purposes. A general factorial design 2 × 2 × 3 was proposed to design 12 different Ca-alginate capsules. Significant differences on the morphological, physical, and mechanical properties of the capsules were analysed by three-way ANOVA and Tukey HSD Post Hoc analyses. The effect of the type of oil on the self-healing capacity of cracked bitumen samples was also evaluated. The main results showed that the design parameters and their interactions significantly affected the morphological, physical, and mechanical properties of the capsules. Capsules synthesised via syringe pump method, with virgin cooking oil and 2% alginate was the most appropriate for asphalt self-healing purposes since its uniform morphology, encapsulation efficiency up to 80%, thermal degradation below 5% wt., and compressive strength above the reference asphalt compaction load of 10 N. Finally, the healing tests showed that virgin cooking oil can be potentially used as a rejuvenator to promote asphalt crack-healing.

Biobased Spore Microcapsules for Asphalt Self-Healing.

Asphalt pavements and bituminous composites are majorly damaged by bitumen aging and fatigue cracking by traffic load. To add, maintenance and reparation of asphalt pavements is expensive and also releases significant amounts of greenhouse gases. These issues can be mitigated by promoting asphalt self-healing mechanisms with encapsulated rejuvenators. The ability of the required microcapsules to be resilient against high temperatures, oxidation, and mechanical stress is essential to promote such self-healing behavior without compromising the field performance of the asphalt pavement. This work proposes, for the first time, the use of extremely resistant biobased spores for the encapsulation of recycled oil-based rejuvenators to produce more resilient self-healing pavements. Spore encapsulants were obtained from natural spores (Lycopodium clavatum) by applying different chemical treatments, which enabled the selection of the best morphologically intact and clean spore encapsulant. The physical, morphological, and physicochemical changes were examined using fluorescence images, ATR-FTIR, SEM, size distribution, XRD, TGA and DSC analyses. Sunflower oil was used as the encapsulated rejuvenator with an optimal sol colloidal mixture for sporopollenin-oil of 1:5 (gram-to-gram). Vacuum, passive, and centrifugal encapsulation techniques were tested for loading the rejuvenator inside the clean spores and for selecting the best encapsulation technology. The encapsulation efficiency and the profiles of the accelerated release of the rejuvenator from the loaded spores over time were studied, and these processes were visualized with optical and inverted fluorescence microscopy. Vacuum encapsulation was identified as the best loading technique with an encapsulation efficiency of 93.02 ± 3.71%. The rejuvenator was successfully encapsulated into the clean spores, as observed by optical and SEM morphologies. In agreement with the TGA and DSC, the microcapsules were stable up to 204 °C. Finally, a self-healing test was conducted through fluorescence tests to demonstrate how these biobased spore microcapsules completely heal a crack into an aged bitumen sample in 50 min.

Effect of the Addition of High-Protein Hydrolyzed Flour from Oncorhynchus mykiss Byproducts on the Properties of an Extruded Feed.

This work aims to evaluate the effect of the addition of a high-protein hydrolyzed (HPH) flour from the chemical silage of trout (Oncorhynchus mykiss) residues on the parameters of the extrusion system physicochemical transformations and the microstructure of the extrudate. During the extrusion process, the materials used for the study were the HPH flour obtained from trout by chemical silage, fishmeal, and cassava starch. The extrudate's microstructural changes were evaluated by determining the porosity, scanning electron microscopy, the chemical changes, the amino acid profile, residual formic and lactic acid content, the molecular mass profile, the grade of hydrolysis, and in vitro digestibility. The results showed pellets with high durability due to the cohesiveness of the hydrolyzed protein flour but at the same time with low hardness due to the high porosity achieved. The monitoring carried out to the changes in the protein, such as the degree of hydrolysis, water-soluble protein, and molecular mass profile, verify the binding effect of the high-protein hydrolyzed flour during the extrusion process. Finally, the high-resolution optical microscopy methodology presented a high correlation with the phenomena presented in the experiment.

Chip-based digital Polymerase Chain Reaction as quantitative technique for the detection of PIK3CA mutations in breast cancer patients.

Background: PIK3CA is a gene frequently mutated in breast cancer. With the FDA approval of alpelisib, the evaluation of PIK3CA for activating mutations is becoming routinely. Novel platforms for gene analysis as digital PCR (dPCR) are emerging as a potential replacement for the traditional Sanger sequencing. However, there are still few studies on chip-based dPCR to detect mutations in tumor samples. Thus, this cross-sectional study aimed to assess the sensibility of a chip-based dPCR to detect and quantify PIK3CA mutations and compare its performance with Sanger sequencing. Materials and Methods: Tumor samples from 57 breast cancer patients (22 pre-treatment samples, 32 tumors after neoadjuvant chemotherapy, and three lymph nodes) were collected and analyzed by Sanger sequencing and dPCR for the three PIK3CA most relevant mutations (p.E545K, p. H1047R, and p. H1047L). Digital PCR sensitivity, specificity, and overall performance were estimated by contingency tables, receptor operator characteristic (ROC), and area under the curve (AUC). Association of PIK3CA mutations with clinicopathological variables was conducted. Results: Sanger sequencing identified PIK3CA mutations in six patients (10.5%), two with p. H1047R, and four with p. E545K. Digital PCR confirmed those mutations and identified 19 additional patients with at least one mutation. Comparison between dPCR and Sanger sequencing showed a sensitivity of 100% (95% CI 53-100%), and a specificity of 84.2% (95% CI 83-84.2%). Besides, p. H1047R mutation detected by dPCR showed a significant association with breast cancer phenotype (p = 0.019) and lymphatic nodes infiltration (p = 0.046). Conclusions: Digital PCR showed a high sensitivity to detect mutations in tumor samples and it might be capable to detect low-rate mutations and tumor subpopulations not detected by Sanger sequencing.

Quinoa Snack Production at an Industrial Level: Effect of Extrusion and Baking on Digestibility, Bioactive, Rheological, and Physical Properties.

This research aimed to produce gluten-free snacks on a pilot scale from quinoa flour. These snacks experienced an extrusion process, followed by baking. The effects of these technological processes on carbohydrate and protein digestibility, extractable phenolic compounds (EPP), hydrolyzable phenolic compounds (HPP), antioxidant capacity, and physical properties were evaluated in raw quinoa flour and extruded snacks. Extrusion increased digestible starch (RDS) from 7.33 g/100 g bs to 77.33 g /100 g bs. Resistant starch (RS) showed a variation of 2 g/100 g bs. It is noteworthy that protein digestibility increased up to 94.58 g/100 bs after extrusion and baking. These processes increased HPP content, while EPP and carotenoid content decreased. The samples showed significant differences (p < 0.05) in the antioxidant properties determined through the DPPH and ABTS methods. Values of 19.72 ± 0.81 µmol T/g were observed in snacks and 13.16 ± 0.2 µmol T/g in raw flour, but a reduction of up to 16.10 ± 0.68 µmol T/g was observed during baking. The baking process reduced the work of crispness (Wcr) from 0.79 to 0.23 N.mm, while the saturation (C*) was higher in baked ones, showing higher color intensity. The baking process did not influence the viscosity profile. The results in this study respond to the growing interest of the food industry to satisfy consumer demand for new, healthy, and expanded gluten-free snacks with bioactive compounds.

Caries prevalence and its association with brushing habits, water availability, and the intake of sugared beverages.

BACKGROUND. With Dental Caries being the most common disease amongst children in the world today, there is a need to fully understand risk factors that may be related to caries prevalence and how they could be best addressed. AIM. The aim of this study was to evaluate soda, juice, sugared-beverage intake, brushing habits, and community water source availability as they relate to the prevalence of both noncavitated and cavitated caries lesions in small rural villages in Mexico. DESIGN. The International Caries Detection and Assessment System (ICDAS) was used in children from small, isolated, villages in Mexico. Risk factors were assessed via questionnaires. RESULTS. Caries prevalence in the villages was very high, ranging from 94.7% to 100% of the children studied. The mean number of surfaces with lesions per child (D1MFS + d1mfs) having scores ≥1 (noncavitated and cavitated) ranged from 15.4 ± 11.1 to 26.6 ± 15.2. Many of the children reported drinking beverages containing sugar. CONCLUSIONS. Drinking sugared beverages, poor oral hygiene habits, and lack of access to tap water were identified as risk factor for caries in this sample of residents of rural Mexico.

Mortality in cutaneous malignant melanoma and its association with Neutrophil-to-Lymphocyte ratio.

INTRODUCTION: Cutaneous malignant melanoma (CMM) incidence has risen rapidly in the last 50 years. Poor progression and high mortality characterize CMM, making a thorough understanding of progression and associated factors essential for optimizing care. AIMS: We assessed the association between the Neutrophil-to-Lymphocyte Ratio (NLR) and mortality in adults with CMM from an entirely mixed-race Hispanic population during 12 consecutive years of extensive follow-up. MATERIAL & METHODS: We performed a retrospective cohort study in a tertiary hospital in Peru. NLR was categorized with a cutoff value higher or equal than 3. We collected demographic variables, laboratory results and treatments at baseline of follow-up. Cox regression analysis was performed, and we calculated crude and adjusted hazard ratios (HR) and their 95% confidence interval (95%CI). RESULTS: The analysis was from 615 CMM cases, and there were 378 deaths. Most melanomas (63.6%) were acral lentiginous. The crude analysis showed that high NLR is a risk factor for mortality, HR = 2.52; 95%CI (2.03-3.14). High NRL ratio remains statistically significant after adjusting for confounding variables, aHR = 1.61; 95%CI (1.16-2.24). Other risk factors for mortality were clinical stages III and IV, older than 60 years, females and greater Breslow thickness. CONCLUSIONS: We concluded that high NRL ratio is a risk factor for mortality and should be monitored in every patient who is diagnosed with malignant melanoma during their first blood count. It should then be carried out in follow-up controls for patients of clinical stage III and IV only, or in patients who present a relapse.

Oncoplastic surgery for the conservative treatment of breast cancer in Perú's National Cancer Institute.

BACKGROUND: Oncoplastic surgery for breast cancer (OPS) has been a surgical trend for the past 25 years. In 2012, OPS has been introduced as the standard treatment for a selected group of patients at the National Cancer Institute of Peru (INEN). The aim of this study is to describe our findings. METHODS: This is a retrospective and descriptive study that identified demographics, tumour-pathologic features and includes patients solely treated since diagnosis until late follow-up at INEN. These OPS patients were identified from the conservative treatment patients group by review of medical charts and creation of a database for periods December 2005 through December 2015. RESULTS: A total of 146 patients were ruled in by the inclusion criteria. All patients were Peruvian females, 56.2% being 51 or older. 93.8% had core biopsy diagnosis of breast cancer and 52.1% located at the upper outer quadrant. 79.5% patients had upfront OPS and the round block (43.2%) and reduction/mastopexy (23.3%) were the most used techniques. pT2 was the most frequent size (54.7%). We achieved negative margins in 134 patients (93.2%) in a single procedure. Of 29 patients, who had neoadjuvant treatment, 11 achieved pCR. Only 5.5% had pN2 or higher. 95.2% received complimentary external beam radiotherapy. CONCLUSIONS: OPS has proven to be a reliable surgical option, both for aesthetic and oncologic outcomes. Important points for achieving these results are breast surgeons having properly trained under the OPS philosophy and knowing the patients' characteristics for correct technique selection.

Absceso subpectoral como diagnóstico diferencial de hombro doloroso: reporte de un caso / Subpectoral abscess as a differential diagnosis of painful shoulder: a case report

Los síndromes dolorosos del hombro son relativamente comunes en la práctica clínica. Habitualmente son causados por un número limitado de patologías. Dentro de los diagnósticos diferenciales, el pinzamiento subacromial, las lesiones aisladas del manguito rotador, capsulitis adhesiva, tendinitis cálcica, patología degenerativa de las articulaciones glenohumeral y acromioclavicular, y la inestabilidad crónica del hombro, son causas comunes. Causas infrecuentes son la rotura del tendón del bíceps, neuralgias, patología infecciosa articular y tumores del hombro. Un absceso subpectoral sin sintomatología infecciosa clara es una causa extremadamente rara de hombro doloroso en el adulto. Presentamos el caso de un paciente de 60 años, que inicia con un cuadro de hombro doloroso cuya causa se identifica como un absceso subpectoral por staphylococcus aureus que se maneja con drenaje quirúrgico y tratamiento antibiótico endovenoso con buenos resultados.

Painful shoulder syndromes are commonly caused by a limited assortment of pathologies. Differential diagnosis include rotator cuff impingement syndrome, rotator cuff tears, adhesive capsulitis, calcific tendonitis, degenerative disease of the joint including acromio-clavicular and gleno-humeral joints and chronic instability. Less common causes are labral tears, biceps tendon rupture, soft tissue infection, neurologic disease, joint infection and shoulder tumors. A subpectoral abscess without infectious clinical features is a very rare cause of shoulder pain in adults. We present the case of a 52 years old male who develops a painful shoulder syndrome caused by a staphylococcus aureus subpectoral abscess, treated by surgical drainage and intravenous antibiotic therapy with good results.

Competencias esenciales en salud pública: un marco regional para las Américas / Core competencies in public health: a regional framework for the Americas

Se describe la respuesta a un llamado de la Organización Panamericana de la Salud, realizado en 2010, para conformar el Marco Regional de Competencias Esenciales en Salud Pública, con el propósito de apoyar a los Estados de las Américas en sus esfuerzos por fortalecer las capacidades de sus sistemas de salud pública, en tanto estrategia para el desempeño óptimo de las Funciones Esenciales de Salud Pública. El proceso metodológico de dicha respuesta se dividió en cuatro fases. En la primera se convocó a un equipo de expertos que definieron la metodología a seguir durante un taller en el Instituto Nacional de Salud Pública de México en 2010. La segunda fase fue la constitución de grupos de trabajo, utilizando dos criterios: experiencia y composición multidisciplinaria, lo cual derivó en un equipo regional con 225 integrantes de 12 países. Estos equipos elaboraron una propuesta inicial de 88 competencias. En la tercera fase se realizó una validación cruzada de las competencias, cuyo número se redujo a 64. Durante la cuarta fase, que incluyó dos talleres en marzo (Medellín, Colombia) y junio (Lima, Perú) de 2011, las discusiones se centraron en analizar la correspondencia de los resultados con la metodología.

The response is described to the 2010 call from the Pan American Health Organization to develop a Regional Framework on Core Competencies in Public Health, with a view to supporting the efforts of the countries in the Americas to build public health systems capacity as a strategy for optimal performance of the Essential Public Health Functions. The methodological process for the response was divided into four phases. In the first, a team of experts was convened who defined the methodology to be used during a workshop at the National Institute of Public Health of Mexico in 2010. The second phase involved formation of the working groups, using two criteria: experience and multidisciplinary membership, which resulted in a regional team with 225 members from 12 countries. This team prepared an initial proposal with 88 competencies. In the third phase, the competencies were cross-validated and their number reduced to 64. During the fourth phase, which included two workshops, in March 2011 (Medellín, Colombia) and June 2011 (Lima, Peru), discussions centered on analyzing the association between the results and the methodology.
