RESUMO
INTRODUCTION: Patients with cervical cancer (CC) may experience local recurrence very often after treatment; when only clinical parameters are used, most cases are diagnosed in late stages, which decreases the chance of recovery. Molecular markers can improve the prediction of clinical outcome. Glycolysis is altered in 70% of CCs, so molecular markers of this pathway associated with the aggressiveness of CC can be identified. METHODS: The expression of 14 glycolytic genes was analyzed in 97 CC and 29 healthy cervical tissue (HCT) with microarray; only LDHA and PFKP were validated at the mRNA and protein levels in 36 of those CC samples and in 109 new CC samples, and 31 HCT samples by qRT-PCR, Western blotting, or immunohistochemistry. A replica analysis was performed on 295 CC from The Cancer Genome Atlas (TCGA) database. RESULTS: The protein expression of LDHA and PFKP was associated with poor overall survival [OS: LDHA HR = 4.0 (95% CI = 1.4-11.1); p = 8.0 × 10-3 ; PFKP HR = 3.3 (95% CI = 1.1-10.5); p = 4.0 × 10-2 ] and disease-free survival [DFS: LDHA HR = 4.5 (95% CI = 1.9-10.8); p = 1.0 × 10-3 ; PFKP HR = 3.2 (95% CI = 1.2-8.2); p = 1.8 × 10-2 ] independent of FIGO clinical stage, and the results for mRNA expression were similar. The risk of death was greater in patients with overexpression of both biomarkers than in patients with advanced FIGO stage [HR = 8.1 (95% CI = 2.6-26.1; p = 4.3 × 10-4 ) versus HR = 7 (95% CI 1.6-31.1, p = 1.0 × 10-2 )] and increased exponentially as the expression of LDHA and PFKP increased. CONCLUSIONS: LDHA and PFKP overexpression at the mRNA and protein levels was associated with poor OS and DFS and increased risk of death in CC patients regardless of FIGO stage. The measurement of these two markers could be very useful for evaluating clinical evolution and the risk of death from CC and could facilitate better treatment decision making.

BACKGROUND: Lung cancer (LC) screening improves LC survival; the best screening method in terms of improving survival is low-dose CT (LDCT), outpacing chest X-ray and sputum cytology. METHODS: A consensus of experts in Argentina was carried out to review the literature and generate recommendations for LC screening programmes. A mixed-method study was used with three phases: (1) review of the literature; (2) modified Delphi consensus panel; and (3) development of the recommendations. The Evidence to Decision (EtD) framework was used to generate 13 evaluation criteria. Nineteen experts participated in four voting rounds. Consensus among participants was defined using the RAND/UCLA method. RESULTS: A total of 16 recommendations scored ≥7 points with no disagreement on any criteria. Screening for LC should be performed with LDCT annually in the population at high-risk, aged between 55 and 74 years, regardless of sex, without comorbidities with a risk of death higher than the risk of death from LC, smoking ≥30 pack-years or former smokers who quit smoking within 15 years. Screening will be considered positive when finding a solid nodule ≥6 mm in diameter (or ≥113 mm3) on baseline LDCT and 4 mm in diameter if a new nodule is identified on annual screening. A smoking cessation programme should be offered, and cardiovascular risk assessment should be performed. Institutions should have a multidisciplinary committee, have protocols for the management of symptomatic patients not included in the programme and distribute educational material. CONCLUSION: The recommendations provide a basis for minimum requirements from which local institutions can develop their own protocols adapted to their needs and resources.

In this pilot study, we characterize and evaluate 3D-printed swabs for the collection of nasopharyngeal and oropharyngeal secretion samples for the SARS-CoV-2 detection. Swabs are made with the fused deposition modeling technique using the biopolymer polylactic acid (PLA) which is a medical-grade, biodegradable and low-cost material. We evaluated six swabs with mechanical tests in a laboratory and in an Adult Human Simulator performed by healthcare professionals. We proved the adequacy of the PLA swab to be used in the gold standard reverse transcriptase-polymerase chain reaction (qRT-PCR) for viral RNA detection. Then, we did in vitro validation for cell collection using the 3D-printed swabs and RNA extraction for samples from 10 healthy volunteers. The 3D-printed swabs showed good flexibility and maneuverability for sampling and at the same time robustness to pass into the posterior nasopharynx. The PLA did not interfere with the RNA extraction process and qRT-PCR test. When we evaluated the expression of the reference gene (RNase P) used in the SARS-CoV-2 detection, the 3D-printed swabs showed good reproducibility in the threshold cycle values (Ct = 23.5, range 19-26) that is comparable to control swabs (Ct = 24.7, range 20.8-32.6) with p value = 0.47. The 3D-printed swabs demonstrated to be a reliable, and an economical alternative for mass use in the detection of SARS-CoV-2.

The current knowledge society has driven an unprecedented mobility of people, especially scientists, from emerging economies to developed countries. This mobility can allow the development of human talent and the access to first class infrastructure and resources, but it can also mean a loss for emerging economies due to the phenomenon of brain drain. To counteract this situation, some countries in Latin America and the Caribbean have developed models for the articulation of their scientific diaspora in projects and programs, with the aim of exchanging knowledge and capitalizing on human and technical resources to advance science, technology and innovation systems. Likewise, science diplomacy has become a tool for interlinking the work of various actors in order to advance the solution of national, transnational or global problems through scientific advice. Scientific diasporas are vital in new structures of cooperation, enabling them to innovate and solve problems jointly, advising their countries of origin and articulating policies and programs. This research seeks to analyze the interactions and initiatives identified between the organized scientific diaspora from Latin America and the Caribbean and their countries of origin in relation to science diplomacy processes, providing recommendations and proposals for public policy to improve the interaction between the diaspora and the governments of their countries of origin. Results show that diaspora organizations from Latin America and the Caribbean engage with governmental and non-state actors and are active science diplomacy stakeholders promoting the scientific developments of their country or their researchers, as well as enabling access to research resources creating alliances for scientific, institutional and academic collaborations. In the cases studied, these efforts are planned and executed by the diaspora without responding to any science diplomacy strategy of the country. Policies and programs are needed to effectively link the scientific diaspora organizations to the interests of the countries.
RESUMO
Macrophages are mediators of inflammation having an important role in the pathogenesis of cardiovascular diseases. Recently, a pro-inflammatory subpopulation, known as metabolically activated macrophages (MMe), has been described in conditions of obesity and metabolic syndrome where they are known to release cytokines that can promote insulin resistance. Dyslipidemia represents an important feature in metabolic syndrome and corresponds to one of the main modifiable risk factors for the development of cardiovascular diseases. Circulating monocytes can differentiate into macrophages under certain conditions. They correspond to a heterogeneous population, which include inflammatory and anti-inflammatory subsets; however, there is a wide spectrum of phenotypes. Therefore, we decided to investigate whether the metabolic activated monocyte (MoMe) subpopulation is already present under dyslipidemia conditions. Secondly, we assessed whether different levels of cholesterol and triglycerides play a role in the polarization towards the metabolic phenotype (MMe) of macrophages. Our results indicate that MoMe cells are found in both healthy and dyslipidemia patients, with cells displaying the following metabolic phenotype: CD14varCD36+ABCA1+PLIN2+. Furthermore, the percentages of CD14++CD68+CD80+ pro-inflammatory monocytes are higher in dyslipidemia than in healthy subjects. When analysing macrophage differentiation, we observed that MMe percentages were higher in the dyslipidemia group than in healthy subjects. These MMe have the ability to produce high levels of IL-6 and the anti-inflammatory cytokine IL-10. Furthermore, ABCA1 expression in MMe correlates with LDL serum levels. Our study highlights the dynamic contributions of metabolically activated macrophages in dyslipidemia, which may have a complex participation in low-grade inflammation due to their pro- and anti-inflammatory function.

All 4 dengue viruses (DENV) cause sporadic outbreaks of human disease in the Rio Grande Valley along the US-Mexico border. In addition, West Nile virus (WNV) is enzootic in most border communities, and is the only arbovirus known to cause human disease in the El Paso, Texas community. In an effort to determine if DENV were also endemic in the El Paso community, a serosurvey was conducted among mothers at the time of delivery of their babies in selected hospitals. Cord-blood plasma samples obtained from mothers were tested for DENV antibody by an enzyme-linked immuno-sorbent assay (ELISA), plaque reduction neutralization test (PRNT) and a multiplex microsphere immunoassay. All DENV antibody positive plasma samples were also tested for WNV antibody by the same assays to consider the possibility that DENV antibody positive samples reflected WNV cross reactive antibody. The results indicated that 0.74% (11/1,472) of the mothers had a previous DENV infection and that 3.3% (48/1,472) had a previous WNV infection. Of these mothers, 0.20% (3/1,472) had antibody to both DENV and WNV as evidence of infection by both viruses. The results indicated that 0.2% (3/1472) of the mothers were positive for antibody to only WNV envelope, thus suggesting an undetermined flavivirus infection. Although 6 of the 11 DENV antibody positive mothers did not have a history of travel to a DENV endemic country, the findings of this survey provided further evidence of local transmission of WNV and suggested the possibility of focal autochthonous transmission of DENV in the El Paso community.

The antisynthetase syndrome is an autoimmune inflammatory miopathy that may show interstitial pulmonary involvement. The presence of antisynthetase antibodies is related to a higher incidence of interstitial pulmonary involvement. The imaging and anatomopathological pattern of diffuse interstitial pulmonary disease (DIPD) is variable, mainly inflammatory. This case describes a female patient with inflammatory miopathy and pulmonary involvement who shows a tomographic pattern of organizing pneumonia. It is important to increase suspicion for antisynthetase syndrome in a patient with pulmonary involvement and miopathy, where multidisciplinary evaluation is fundamental to reach a diagnosis. A review of the evidence is made in the discussion of the case.

UNLABELLED: The (As) arsenic exposure is a risk factor for causing disturbances in the endocrine organs. OBJECTIVE: To evaluate if sub-chronic As exposure during the pre- and postnatal development causes disturbances in the puberty. Moreover, determine adverse effects of As on the ovarian follicle and adrenocortical cell maturation. METHODS: Females adult Wistar rats were exposed to sodium arsenite at 3 ppm calculated as As in drinking water from mating, gestation. Following the birth, the female offspring continued exposured to As via lactation. Weaned pups received the same As treatment as mothers, until they were 1-4 months (mo) old. At these ages, blood sampling and tissue harvest were done. The tissues were fixed in situ with 4% paraformaldehyde in phosphate buffer. After the perfusion the ovaries, uterus, adrenal glands were harvested, dissected out, weighted. The ovaries and the adrenal glands were processed to paraffin and sectioned at 5 µM and stained with hematoxylin and eosin for light microscopy. STATISTICAL ANALYSIS: Comparisons between groups were made by unpaired t-test or nonparametric Mann-Whitney test as appropriate. RESULTS: 100% As treated rats at 1 mo of age were at diestrous stage, with low estradiol E2. As treatment caused disturbances in the morphology of the ovarian cell consisting in DNA damage evidenced by picknotic chromatin, cariorexis, significant cytoplasmic vacuolization and also vasculature damaged. Arrest in follicle maturation was also present. CONCLUSIONS: We found that the onset of puberty in the As treated rats was 1 mo delayed since vagina was still closed, the vaginal smear showed that they were at diestrus stage with plasma low E2 levels.
