Abstract
BACKGROUND Previous studies have indicated the association between poor oral health and depression in adults. This study evaluated oral and social functions contribution to the association between tooth loss and depressive symptoms in Chilean individuals. METHODS We used data from the Chilean National Health Survey. The number of remaining teeth (≤19 versus ≥20 teeth) and anterior tooth losses were the exposure variables. Outcome was depression, measured through a self-report question and with the Composite International Diagnostic Interview - Short Form (CIDI SF). Mediating variables were determined by five questions, including problems regarding "speaking", "pain and suffering", "eating", "daily activities", and "social relationships". We performed logistic regression models adjusted by multiple confounders variables. Finally, we calculated indirect, direct effect, total effect, and the proportion mediated (PM). RESULTS We included 5383 participants. The self-reported depression and suspected depression prevalence were 22,1 % and 14,0 % respectively. The total effect of fewer remaining teeth (≤19) on self-reported depression was 1.21 (95 % CI 1.02-1.44), and 1.09 (95 % CI 0.90-1.33) for suspected depression. All five variables of oral and social functions significantly mediated the association between tooth loss and depression. Feeling uncomfortable when speaking or eating discomfort were the most significant mediators. LIMITATIONS The mediation analysis should be interpreted with caution due to the cross-sectional design. CONCLUSIONS Deterioration of oral and social functions was a significant mediator in the association between tooth loss and depression, in particular feeling uncomfortable when speaking or eating. This mechanism should be considered in interventions to improve mental health.

Abstract
BACKGROUND AND OBJECTIVE Forkhead box-O 1 (FOXO1) is a transcription factor actively involved in oral wound healing at the epithelial barrier. However, less is known regarding the role of FOXO1 during the tissue repair response in the connective tissue compartment. This study explored the involvement of FOXO1 in the modulation of fibroblast activity related to wound healing. METHODS Primary cultures of human gingival fibroblasts were obtained from four healthy young donors. Myofibroblastic differentiation, collagen gel contraction, cell migration, cell spreading, and integrin activation were evaluated in the presence or absence of a FOXO1 inhibitor (AS1842856). Variations in mRNA and proteins of interest were evaluated through qRT-PCR and western blot, respectively. Distribution of actin, α-smooth muscle actin, and β1 integrin was evaluated using immunofluorescence. FOXO1 and TGF-β1 expression in gingival wound healing was assessed by immunohistochemistry in gingival wounds performed in C57BL/6 mice. Images were analyzed using ImageJ/Fiji. ANOVA or Kruskal-Wallis test followed by Tukey's or Dunn's post-hoc test was performed. All data are expressed as mean ± SD. p < .05 was considered statistically significant. RESULTS FOXO1 inhibition caused a decrease in the expression of the myofibroblastic marker α-SMA along with a reduction in fibronectin, type I collagen, TGF-β1, and β1 integrin mRNA level. The FOXO1 inhibitor also caused decreases in cell migration, cell spreading, collagen gel contraction, and β1 integrin activation. FOXO1 and TGF-β1 were prominently expressed in gingival wounds in fibroblastic cells located at the wound bed. CONCLUSION The present study indicates that FOXO1 plays an important role in the modulation of several wound-healing functions in gingival fibroblast. Moreover, our findings reveal an important regulatory role for FOXO1 on the differentiation of gingival myofibroblasts, the regulation of cell migration, and collagen contraction, all these functions being critical during tissue repair and fibrosis.

Abstract
Cardiovascular diseases are the leading cause of death worldwide, and arterial hypertension is a recognized cardiovascular risk factor that is responsible for high morbidity and mortality. Arterial hypertension is the result of an inflammatory process that results in the remodeling and thickening of the vascular walls, which is associated with an immunological response. Previous studies have attempted to demonstrate the relationship between oral disease, inflammation, and the development of systemic diseases. Currently, the existence of an association between periodontitis and hypertension is a controversial issue because the underlying pathophysiological processes and inflammatory mechanisms common to both diseases are unknown. This is due to the fact that periodontitis is a chronic inflammatory disease that affects the interface of teeth and surrounding tissues. However, the most likely explanation for understanding this association is related to low-grade chronic inflammation. An initial path in the study of the relationship between the mentioned pathologies is the possibility of an epigenetic influence, mediated by noncoding RNAs as microRNAs. Thus, in the present review we describe the role of microRNAs related to arterial hypertension and/or periodontitis. In addition, we identified 13 common microRNAs between periodontitis and hypertension. According to the predictions of the DIANA-mirPath program, they can regulate genes involved in 52 signaling pathways.

Abstract
The signal transducer and activator of transcription 3 (STAT3) is a transcription factor mainly activated by phosphorylation in either tyrosine 705 (Y705) or serine 727 (S727) residues that regulates essential processes such as cell differentiation, apoptosis inhibition, or cell survival. Aberrant activation of STAT3 has been related to development of nearly 50% of human cancers including clear cell renal cell carcinoma (ccRCC). In fact, phosho-S727 (pS727) levels correlate with overall survival of ccRCC patients. With the aim to elucidate the contribution of STAT3 phosphorylation in ccRCC development and progression, we have generated human-derived ccRCC cell lines carrying STAT3 Y705 and S727 phosphomutants. Our data show that the phosphomimetic substitution Ser727Asp facilitates a pro-tumoral phenotype in vitro, in a Y705-phosphorylation-independent manner. Moreover, we describe that STAT3 phosphorylation state determines the expression of different subsets of target genes associated with distinct biological processes, being pS727-dependent genes the most related to cellular hallmarks of cancer. In summary, the present study constitutes the first analysis on the role of overall STAT3 phosphorylation state in ccRCC and demonstrates that pS727 promotes the expression of a specific subset of target genes that might be clinically relevant as novel biomarkers and potential therapeutic targets for ccRCC.

Abstract
OBJECTIVES Previous studies have established an association between tooth loss and depression. However, longitudinal evidence is scarce and needs to be verified in other populations. The aim of this study was to examine the longitudinal association between the number of remaining teeth and incident depression at 2- and 4-years follow-up in individuals enrolled in the Maule cohort (MAUCO) in Chile. METHODS This prospective study used the information of individuals, aged 38 to 74 years, excluding those with depression at baseline. The number of remaining teeth at baseline was determined in four groups: "20 or more teeth", "10 to 19 teeth", "1 to 9 teeth" and "no natural teeth". Depression was measured through the PHQ-9. Logistic regression was performed to calculate the odds ratios (OR) for incidence depression at both periods of follow-ups, adjusting for age, sex, educational attainment, diabetes mellitus II, and stressful events at follow-up. Also, we performed adjusted multinomial logistic models to analysis the association between the number of remaining teeth and depression severity. RESULTS In total individuals (n = 3335 at follow 1, n = 2461 at follow 2), all groups have ORs for incident depression above 1 considering 20 or more teeth as reference. In men, those with 10-19 teeth have 2.44 times higher odds of incident depression than those with 20 or more teeth (OR 2.44, CI 95% 1.33-4.50). Edentulous subjects at 4 years follow-up had 2.24 times higher odds of depression than those with more than 20 teeth (OR 2.24 CI 95%1.35-3.72). In women, the ORs (CI 95%) of incident depression were 2.56 (1.50-4.39), 1.56 (1.02-2.40) and 1.27 (0.90-1.81) for "none", "1-9", "10-19" respectively in comparison to the reference group. In edentulous individuals at baseline, the odds for each of the comparisons "mild vs no", "moderate vs no", "moderately severe vs no" and "severe vs no" were above 1, at both follow-ups. CONCLUSION Individuals with less than 20 teeth in the mouth could had higher odds of incident depression at 2- and 4-years follow-up, with differences between men and women. Also, in our study, edentulism was associated with increased odds of incident depression at 4-years follow-up in women, and with higher levels of severity of depressive symptoms.

Abstract
AIM To identify Prediabetes (PreD) as early and serious diabetes step using clinical-biochemical characteristics in the population of the Primary Prevention Diabetes Buenos Aires (PPDBA) study. METHODS PPDBA Study evaluated benefits of adopting healthy lifestyles to prevent T2D. It recruited people 45-75 years of age with PreD (impaired fasting glycaemia [IFG], impaired glucose tolerance [IGT] or both, American Diabetes Association criteria), using an opportunistic approach. They completed a FINDRISC questionnaire, and those with a score ≥13 points were invited to participate. When they accepted, we performed an oral glucose tolerance test (OGTT) with a complete lipid profile and HbA1c while physicians completed a clinical history. We recruited 367 persons, and depending on OGTT results, the sample was divided into normals (NGT), PreD, or with diabetes (last one was excluded in our analysis). Data were statistically analyzed using parametric and nonparametric tests and logistic regression to identify parameters associated with PreD. RESULTS From the recruited (n = 367) 47.7% have NGT, 48.5% PreD and 3.8% unknown T2D (excluded). People with PreD were significantly older, with a higher percentage of overweight/obesity, BMI, and larger waist circumference than NGT. They also showed significantly higher fasting and 2 h post glucose load, HbA1c, and triglyceride levels. No significant differences were recorded in the blood pressure, lipid profile though both groups had abnormally high LDL-c values. They also had a larger percentage of TG/HDL-c ratios (insulin resistance indicator) (55% vs. 37.5%). Logistic regression analysis showed that PreD was significant associated with age, waist circumference, and triglyceride above target values. CONCLUSION Our findings showed that clinical and biochemical parameters were significantly different between people with PreD and those with NGT. This evidence supports the concept that PreD is a serious dysfunction, which should be early diagnosed and treated properly to prevent its transition to T2D and its complications.

Abstract
OBJECTIVE The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of the sliding sign on transvaginal ultrasound (TVS) in detecting pouch of Douglas obliteration and bowel involvement in patients with suspected endometriosis, using laparoscopy as the reference standard. METHODS A search for studies evaluating the role of the sliding sign in the assessment of pouch of Douglas obliteration and/or bowel involvement using laparoscopy as the reference standard published from January 2000 to October 2021 was performed in PubMed/MEDLINE, Web of Science, CINAHL, The Cochrane Library, ClinicalTrials.gov and SCOPUS databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the quality of the studies. Analyses were performed using MIDAS and METANDI commands in STATA. RESULTS A total of 334 citations were identified. Eight studies were included in the analysis, resulting in 938 and 963 patients available for analysis of the diagnostic accuracy of the sliding sign for pouch of Douglas obliteration and bowel involvement, respectively. The mean prevalence of pouch of Douglas obliteration was 37% and the mean prevalence of bowel involvement was 23%. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting pouch of Douglas obliteration were 88% (95% CI, 81-93%), 94% (95% CI, 91-96%), 15.3 (95% CI, 10.2-22.9), 0.12 (95% CI, 0.07-0.21) and 123 (95% CI, 62-244), respectively. The heterogeneity was moderate for sensitivity and low for specificity for detecting pouch of Douglas obliteration. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting bowel involvement were 81% (95% CI, 64-91%), 95% (95% CI, 91-97%), 16.0 (95% CI, 9.0-28.6), 0.20 (95% CI, 0.10-0.40) and 81 (95% CI, 34-191), respectively. The heterogeneity for the meta-analysis of diagnostic accuracy for bowel involvement was high. CONCLUSION The sliding sign on TVS has good diagnostic performance for predicting pouch of Douglas obliteration and bowel involvement in women with suspected endometriosis. © 2022 The Authors.

Abstract
Abstract
Study question
What is the accuracy of NGS versus QF-PCR in the Rapid Prenatal Testing?
Summary answer
NGS seems to be a reliable alternative for Rapid Prenatal Testing and expand the aneuploidy screening to all 24 chromosomes.
What is known already
As part of the prenatal care, whenever an invasive testing is needed, rapid prenatal analysis is performed to rule out the most common aneuploidies (i.e., trisomy for chromosomes 13, 18 and 21), using FISH or QF-PCR. Some studies describe the use of the NGS as an alternative to detect genetic alterations in the DNA from amniocytes or chorionic villus sampling (CVS) in Prenatal Genetic Testing.
Study design, size, duration
This research study evaluates the accuracy of NGS analysis for Rapid Prenatal Testing comparing the results with gold standard techniques. A total of 32 amniotic fluid samples clinically analysed by karyotype (n = 3) or QF-PCR (n = 29) were used as reference resulting in: normal male (n = 3); normal female (n = 9); trisomy 13 (n = 3); trisomy 18 (n = 5; one by karyotype); trisomy 21 (n = 10; one by karyotype); partial trisomy 3q26q26/partial monosomy 5p13p15.33 (n = 1; by karyotype); and triploid XXY (n = 1).
Participants/materials, setting, methods
All 32 samples were analysed using an NGS platform validated for PGT-A (Preimplantation Genetic Testing for aneuploidy). Ion ReproSeq™ PGS kit was used for library preparation, Ion Chef™ and Ion S5 System instruments for sequencing and Ion Reporter software for data analysis (Thermo Fisher Scientific, USA), with a proprietary bioinformatics pipeline (v2.0) for the analysis of 24-chromosome aneuploidies and partial duplication/deletions (≥10Mb). NGS results were compared with the reference QF-PCR/Karyotype results for accuracy evaluation.
Main results and the role of chance
When comparing NGS versus QF-PCR/Karyotype results, we observed a 100% concordance for the detection of trisomy 13 (3 out of 3 samples), trisomy 18 (5 out of 5 samples), trisomy 21 (10 out of 10 sample) and partial trisomy 3q/partial monosomy 5p (1 out of 1 sample). We did not identify false positives for any of the chromosomes in which comparison could be done as they were analysed in the reference samples (chromosomes 13, 18, 21, X and Y for QF-PCR reference samples, and all 24 chromosomes for Karyotype reference samples). In one of the samples, the triploid XXY, the NGS profile for the sex chromosomes was compatible either with a normal male result with maternal cell contamination or with a triploid XXY result, and was finally classified as non-informative for NGS.
Limitations, reasons for caution
The NGS cannot identify deletions/duplications <10Mb and mosaicism <30%. The platform used cannot identify some types of polyploidies, therefore, additional analysis (Short Tandem Repeats, karyotype, or SNP-arrays) when normal results are needed. However, improvements in technology that are currently underway will solve this limitation.
Wider implications of the findings
Based on the experience gained since the implantation of the NGS method for the characterization of the chromosomal status of DNA samples, the use of the NGS platform and protocols for the rapid prenatal test samples has as benefit to expand the screening analysis to all 24 chromosomes.

Abstract
The ever-increasing demand for biopharmaceuticals has created the need for improving the overall productivity of culture processes. One such operational concept that is considered is fed-batch operations as opposed to batch operations. However, optimal fed-batch operations require complete knowledge of the cell culture to optimize the culture conditions and the nutrients feeding. For example, when using high-throughput small-scale bioreactors to test multiple clones that do not behave the same, depletion or overfeeding of some key components can occur if the feeding strategy is not individually optimized. Over the recent years, various solutions for real-time measuring of the main cell culture metabolites have been proposed. Still, the complexity in the implementation of these techniques has limited their use. Soft-sensors present an opportunity to overcome these limitations by indirectly estimate these variables in real-time. This manuscript details the development of a new soft-sensor based fed-batch strategy to maintain substrate concentration (glucose and glutamine) at optimal levels in small-scale multi parallel CHO cultures. Two alternatives to the standard feeding strategy were tested: an OUR soft-sensor-based strategy for glucose and glutamine (Strategy 1) and a dual OUR for glutamine and CO2 /alkali addition for glucose soft-sensor strategy (Strategy 2). The results demonstrated the applicability of the OUR soft-sensor based strategy to optimize glucose and glutamine feedings, which yielded a 21% increase in final viable cell density (VCD) and a 31% in erythropoietin (EPO) titer compared with the reference one. However, CO2/alkali addition soft-sensor suffered from insufficient data to relate alkali addition with glucose consumption. As a result, the culture was overfed with glucose resulting in a 4% increase on final VCD, but a 9% decrease in final titer compared to the Reference Strategy. This article is protected by copyright.

Abstract
Background Malignant vascular tumors (MVTs) are rare and often misdiagnosed due to wide range of clinical presentations, varied histology, and exquisite imagining features. We aim to characterize two different types of MVTs of the liver: hepatic angiosarcomas (HA) and hepatic epithelioid hemangioendotheliomas (HEHE). Methods Data on HA and HEHE between 1975 and 2016 were extracted from the SEER database and analyzed. Results A total of 366 patients with HA were identified where 64.2% were male and 79% of White race. The median age at diagnosis was 64 ± 16.2 years. Distant metastasis was found in 24% of patients, regional disease in 22.1%, and localized disease in 21.3%. The median overall survival for HA was 2 months. For HEHE, 120 cases were identified, 32.5% were male and 80% of White race. The median age of diagnosis was 51 ± 16.8 years. Distant metastasis was found in 37.5% of patients, regional disease in 27.5%, and localized disease in 20%. The median overall survival was 182 months. Conclusion Patients’ demographics such as race, age, and gender may assist in elucidating distinct subtypes of MVTs. HA is an aggressive tumor despite intervention. Patients with HEHE tumors have significantly better survival compared to patients with HA. Further studies are needed to deepen our knowledge about the histopathology of these tumors, the outcomes of liver transplantation as a therapeutic alternative, and available molecular targets for MVTs.

Abstract
We analysed long-term outcome of patients receiving haematopoietic allogeneic stem cell transplantation (allo-HSCT) as a first transplant for high-risk Hodgkin lymphoma (HL). One hundred and ninety patients were included in this study, 63% of them had previously received brentuximab vedotin and/or checkpoint inhibitors. Seventy patients (37%) received an unrelated donor allo-HSCT, 99 (51%) had myeloablative conditioning (MAC) and 60% had in vivo T-cell/depleted grafts (TCD). The 100-day cumulative incidence (CI) of grade II-IV acute graft-versus-host disease (GVHD) was 25% and the 3-year CI of chronic GVHD was 38%. The 3-year CI of non-relapse mortality (NRM) and relapse rate were 21% and 38% respectively. After a median follow-up of 58 months, 3-year overall survival (OS) and progression-free survival (PFS) were 58% and 41% respectively. Multivariate analysis showed that, in comparison to reduced-intensity conditioning regimens with or without TCD, MAC using TCD had similar NRM and a lower risk of relapse leading to significantly better OS and PFS. MAC without TCD was associated with higher NRM and worse survival outcomes. These results suggest that in patients with high-risk HL and candidates of allo-HSCT, a MAC strategy with TCD might be the best option.

Abstract
BACKGROUND Monitoring of disease activity in sclerosing dermatoses (SD) can be challenging and tools to support clinical decision-making are lacking. AIM To analyse the impact of high-frequency ultrasonography (HFUS) on the clinical management of SD and to describe the US characteristics of disease activity. METHODS This was a cohort study of patients with various SD [morphoea, systemic sclerosis (SS) and chronic graft-versus-host disease (cGvHD)] who underwent HFUS between January 2017 and August 2019. HFUS criteria for diagnosing active SD were increased Doppler vascularity and/or meeting all B-mode greyscale US signs of activity. Discordance in SD activity between HFUS and clinical examination was evaluated at the time of the first US assessment. Changes in patient management were instituted after HFUS were recorded. RESULTS In total, 72 patients (31 with morphoea, 19 with SS and 22 with cGvHD), who underwent 163 HFUS sessions in total, were included. All HFUS-active morphoea lesions exhibited increased vascularity, and all HFUS-active SS exhibited dermal thickening and dermal hypoechogenicity. HFUS-active cGvHD displayed increased dermal thickness and loss of definition of the dermal-hypodermal junction, and there were signs of panniculitis in 80% of cases and of increased vascularity in 70%. Discordance in disease activity between clinical and HFUS evaluation was found in 17 (23.6%) patients. Changes in clinical management after HFUS were made for 14 (19.4%) patients: treatment discontinuation for 6 patients (42.9%), treatment initiation for 5 (35.7%), medication change for 2 (14.3%) and skin biopsy taken for 1 (7.1%). CONCLUSION HFUS seems an efficacious support tool in the monitoring of SD activity with a notable impact on clinical management. Further studies are warranted to evaluate the impact of HFUS-supported management changes on SD outcomes.

Abstract
BACKGROUND Deep-learning algorithms (DLAs) have been used in artificial intelligence aided ultrasonography diagnosis of thyroid and breast lesions. However, its use has not been described in the case of dermatologic ultrasound lesions. Our purpose was to train a DLA to discriminate benign form malignant lesions in dermatologic ultrasound images. MATERIALS AND METHODS We trained a prebuilt neural network architecture (EfficientNet B4) in a commercial artificial intelligence platform (Peltarion, Stockholm, Sweden) with 235 color Doppler images of both benign and malignant ultrasound images of 235 excised and histologically confirmed skin lesions (84.3% training, 15.7% validation). An additional 35 test images were used for testing the algorithm discrimination for correct benign/malignant diagnosis. One dermatologist with more than 5 years of experience in dermatologic ultrasound blindly evaluated the same 35 test images for malignancy or benignity. RESULTS EfficientNet B4 trained dermatologic ultrasound algorithm sensitivity; specificity; predictive positive values, and predicted negative values for validation algorithm were 0.8, 0.86, 0.86, and 0.8, respectively for malignancy diagnosis. When tested with 35 previously unevaluated images sets, the algorithm´s accuracy for correct benign/malignant diagnosis was 77.1%, not statistically significantly different from the dermatologist's evaluation (74.1%). CONCLUSION An adequately trained algorithm, even with a limited number of images, is at least as accurate as a dermatologic-ultrasound experienced dermatologist in the evaluation of benignity/malignancy of ultrasound skin tumor images devoid of clinical data.

Abstract
OBJECTIVES This study aimed to validate dermatologic ultrasound as a complementary teledermatologic imaging modality in primary and tertiary care centers. METHODS Six primary care centers and 1 tertiary care dermatology department collaborated in the program. Images were sent through the institutional teledermatologic platform to the tertiary care dermatology department. At the reference hospital, ultrasound images and clinical data were received and registered by a physician trained in dermatologic ultrasound. An in-person consultation was scheduled to confirm the teleultrasound diagnosis. The time of response by the tertiary center, quality and size of the teledermatologic image, and concordance with the in-person diagnosis were assessed for each dermatologic lesion. RESULTS A total of 147 teleultrasound consultations with 143 patients (93 women and 50 men; mean age ± SD, 47 ± 23 years) were evaluated between June 2018 and January 2019. Nine teleultrasound consultations (6.1%) were not valid. Discordance between teleultrasound and the in-person diagnosis was evident in 6 of 138 cases (4.3%). Most cases corresponded to benign skin tumors (66.7%), followed by inflammatory skin lesions (15.9%), nonmelanoma skin lesions (13%), and other skin lesions (4.3%). All malignant tumors were detected (sensitivity, 100%), although 2 cases of benign lesions were telediagnosed as malignant (specificity, 97.8%). The positive and negative predictive values of a teleultrasound diagnosis of cutaneous malignancy were 90% and 100%, respectively. CONCLUSIONS Asynchronous primary care teleultrasound combined with dermatologic ultrasound training at tertiary centers is an effective teledermatologic modality.

Abstract
The COVID-19 pandemic is forcing our entire society to adopt numerous changes, at least until an effective treatment and/or vaccine becomes widely available. Because COVID-19 is a new disease that has required us to make complex decisions based on scant evidence, the pandemic is having an enormous impact on our health system. Radiology departments play a fundamental role in the management of COVID-19, both in the diagnosis of the disease and in the posterior management of patients. To ensure the safety of patients and healthcare professionals, it is essential to understand the infection so that safe circuits can be implemented. This article summarizes the pathophysiology of COVID-19 infection and explains the measures that radiology departments need to adopt during the pandemic.

Abstract
Andean uplift played a fundamental role in shaping South American climate and species distribution, but the relationship between the rise of the Andes, plant composition, and local climatic evolution is poorly known. We investigated the fossil record (pollen, leaves, and wood) from the Neogene of the Central Andean Plateau and documented the earliest evidence of a puna-like ecosystem in the Pliocene and a montane ecosystem without modern analogs in the Miocene. In contrast to regional climate model simulations, our climate inferences based on fossil data suggest wetter than modern precipitation conditions during the Pliocene, when the area was near modern elevations, and even wetter conditions during the Miocene, when the cordillera was around ~1700 meters above sea level. Our empirical data highlight the importance of the plant fossil record in studying past, present, and future climates and underscore the dynamic nature of high elevation ecosystems.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) is a measure of systemic inflammation and a prognostic factor for multiple malignancies. This study assesses the value of the NLR as an independent prognostic marker in triple-negative breast cancer (TNBC) and explores the association between dynamic NLR changes and patient outcomes. METHODS The study retrospectively analyzed a prospectively maintained database including patients 18 to 80 years old with TNBC treated at the authors' institution between 2006 to 2016. Clinical and demographic data were collected, including blood test results and treatments received. Age at diagnosis, stage of disease, and NLR scores were tested for association with overall and disease-free survival in uni- and multivariate Cox models. RESULTS The inclusion criteria were met by 329 women with a median age of 58. Most of the patients had early-stage disease (30.1% with stage 1 and 47% with stage 2 malignancy). An NLR higher than 2.84 at diagnosis was associated with decreased overall survival (hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.023-3.176), whereas an NLR higher than 7.82 at any time during the follow-up period was a strong predictor of 5-year mortality (HR, 10.76; 95% CI, 4.193-26.58), independent of age or stage of disease. Patients who experienced recurrence had a higher NLR than their counterparts during the 6 months before recurrence. The NLR also significantly rose during the final 18 months of life (p < 0.01). CONCLUSION The NLR is an important prognostic marker in TNBC, both at diagnosis and during the course of the disease. Moreover, dynamic changes in NLR strongly correlate with disease recurrence and the time of death.

Abstract
BACKGROUND The effect of primary androgen deprivation therapy (ADT) in patients with localized prostate cancer (PCa) has not been well documented. The objective of the present study was to analyze the outcome of tumors treated with ADT as primary therapy in the Spanish Prostate Cancer Registry (19.4% of the series). PATIENTS AND METHODS Patients were classified in three groups: 1) with low/intermediate risk clinically localized tumors; 2) with high risk and locally advanced (T3-4) tumors; 3) with metastatic tumors. Time to castration resistance and overall cancer-specific survival were analyzed. In non-metastatic tumors, survivals in patients treated with ADT were compared with data from patients who underwent local treatments from the Spanish Prostate Cancer Registry. RESULTS 703 cases were analyzed. There were significant differences in the time to castration resistance, which was lower in the group of metastatic tumors. During follow-up, there were 179 deaths (25.5%) of which 89 (12.6%) were due to PCa. After 3 years of ADT, only 14.6% of patients in group 1 had died (1% due to PCa), 20.5% in group 2 and 46.8% in group 3 (9.2% and 31.3% due to PCa, respectively). Cancer-specific survival was significantly worse in group 1 using ADT than radical prostatectomy or radiotherapy. In high-risk and locally advanced tumors, ADT also had a lower cancer-specific survival than local treatments. CONCLUSION A longer time until the castration resistance was observed in patients with well- and intermediate-risk localized tumors treated with ADT. Patients with metastatic tumors showed the shortest time to castration resistance.

Abstract
INTRODUCTION There currently exist no quantitative methods to assess graft viability before the donor procurement procedure. In Europe, around 20% of liver grafts evaluated "in situ" by an experienced surgeon are discarded. The aim of this study is to evaluate the use of the plasma disappearance rate indocyanine green (PDR-ICG) clearance in predicting liver graft rejection to avoid this 20% of futile surgeries. OBJECTIVES To evaluate PDR-ICG as a predictor of liver graft rejection in death brain donors compared with the gold standard evaluation by an experienced surgeon. MATERIAL AND METHODS Prospective observational single center study. From March 2017 to July 2019, 29 donors were included in the study, 17 were men and 12 women with a median age of 68 years ± 16.9 years. Donors had an intensive care unit stay of 2 days ± 4 days. PDR-ICG was measured with PICCO2 monitor. Indocyanine green clearance dose was 0.25 mg/kg injected intravenously in the operating room just before donor procurement procedure is initiated. The surgeon was unaware of the PDR-ICG measure until the decision of graft acceptance was taken. Data regarding the donors and biopsy results were included in a prospective database. RESULTS PDR-ICG measure could be obtained in 10 minutes in all of the cases included. The median PDR-ICG obtained was 18%/min (range, 2.4-31%/min). Graft rejection took place in 15 out of the 29 donors. PDR-ICG value was less than 10%/min in 6 of these rejected grafts and less than 15%/min in 10 donors. All donor grafts with PDR-ICG <15% were discarded. The graft had been discarded in 5 donors with a PDR-ICG >15%. CONCLUSIONS In our study a plasma disappearance rate <10 would have identified the grafts that would be rejected, thus avoiding the displacement work and expense of the surgical team. These results should be confirmed in a multicentric study.

Abstract
Children with mothers with Borderline Personality Disorder (BPD) have a high risk of developing attachment difficulties, and this risk is like to grow when their mothers experienced severe neglect and/or abuse in their childhood and early adolescence. Our objective was to clinically assess and lend support to a small group of young mothers at risk. We recruited mothers aged 18-25, with 1-12 month-old children. None was married, had a stable residence and sexual partner, and most were unemployed. All had early diagnosis of AD, had at present BPD, and had received extended global and residential psychiatric treatment in our Therapeutic Community (SIRIO Project) along their adolescence. We conducted six consecutive 4 h weekly sessions, which were attended by mothers with their babies in the familiar setting of the Community. The explicit aim proposed to them was: “to come to be listened and accompanied and to share their motherhood experiences” with members of our multidisciplinary team (nurse, social worker, therapeutic educator, psychologist and psychiatrist), who were known to them.Fears, somatizations, more-or-less concealed rejection of her baby, apathy, sadness, suspiciousness, jealousy, relational difficulties with their couples and family figures… were common findings that were addressed in the sessions.Main conclusionMinor but positive changes occurred in the dyadic mother-baby relationship. This was more patent concerning breastfeeding, relationships with their couple and extended family and pediatricians, and attitudes toward job seeking. In addition, the frequent contact with these mothers elicited markedly positive reactions in the 8-9 children/adolescents currently residing in our community.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Chikungunya (CHIK) was introduced in The Americas in 2013, spreading rapidly. In 2014, the first imported case was diagnosed in Chile. AIM To identify patients with clinical suspicion of CHIK and describe their clinical and laboratory characteristics. PATIENTS AND METHODS Patients with suspected CHIK were enrolled. All were confirmed by PCR, IgM or IgG CHIK. A structured survey was applied, which included demographic questions, travel characteristics, clinical manifestations, and laboratory results. RESULTS 21 patients were enrolled and CHIK was confirmed in 16, who were further analyzed; 12 were female (75%), average age 39 years (27-52). The Caribbean and South Americawere the most frequent sites of exposure. In 63%, the initial symptom was arthralgia. Most frequent symptoms were myalgias, malaise (both 100%), fever, and polyarthralgia (both 94%). The median duration of arthralgias was 90 days (3-262); in 53% arthralgias lasted ≥ 3 months. Main joints involved were ankles, hands, and wrists; 87% reported invalidating pain. Arthritis lasted longer in men than in women (p < 0.001). 38% of patients presented lymphopenia and one patient mild thrombocytopenia. Two patients required hospitalization, one with severe headaches, the other with acute pyelonephritis. CONCLUSIONS Chikungunya should be suspected in returning travelers presenting with fever and severe polyarthralgia. Travelers to endemic areas should apply prevention measures to avoid mosquito bites.

Abstract
Vasoactive Intestinal Peptide (VIP) is an important immunomodulator of CD4+ cells in normal and pathological conditions, which exerts its anti-inflammatory and immunomodulatory actions through VPAC receptors, VPAC1 and VPAC2. Only a decrease in the expression of VPAC1 mRNA on Th cells upon activation has been reported. Thus, the deepening in the knowledge of the behavior of these receptors may contribute to the design of new therapies based on their activation and/or blockade. In this study, we describe the expression pattern, cellular location and functional role of VIP receptors during the activation of human Th cells in healthy conditions and in early arthritis (EA). The protein expression pattern of VPAC1 did not change with the activation of Th lymphocytes, whereas VPAC2 was up-regulated. In resting cells, VPAC1 was located on the plasma membrane and nucleus, whereas it only appeared in the nucleus in activated cells. VPAC2 was always found in plasma membrane location. VIP receptors signaled through a PKA-dependent pathway in both conditions, and also by a PKA-independent pathway in activated cells. Both receptors exhibit a potent immunomodulatory capacity by controlling the pathogenic profile and the activation markers of Th cells. These results highlight a novel translational view in inflammatory/autoimmune diseases.

Abstract
After injury to periodontal tissues, a sequentially phased healing response is initiated that enables wound closure and partial restoration of tissue structure and function. Wound closure in periodontal tissues involves the tightly regulated coordination of resident cells in epithelial and connective tissue compartments. Multiple cell populations in these compartments synergize their metabolic activities to reestablish a mucosal seal that involves the underlying periodontal connective tissues and the attachment of these tissues to the tooth surface. The formation of an impermeable seal around the circumference of the tooth is of particular significance in oral health since colonization of tooth surfaces by pathogenic biofilms promotes inflammation, which can contribute to periodontal tissue degradation and tooth loss. The reformation of periodontal tissue structures in the healing response centrally involves fibroblasts, which synthesize and organize the collagen fibers that link alveolar bone and gingiva to the cementum covering the tooth root. The synthesis and remodeling of nascent collagen matrices are of fundamental importance for the reestablishment of a functional periodontium and are mediated by diverse, multi-functional fibroblast populations that reside within the connective tissues of gingiva and periodontal ligament. Notably, after gingival wounding, a fibroblast sub-type (myofibroblast) arises, which is centrally involved in collagen synthesis and fibrillar remodeling. While myofibroblasts are not usually seen in healthy, mature connective tissues, their formation is enhanced by wound-healing cytokines. The formation of myofibroblasts is also modulated by the stiffness of the extracellular matrix, which is mechanosensed by resident precursor cells in the gingival connective tissue microenvironment. Here, we consider the cellular origins and the factors that control the differentiation and matrix remodeling functions of periodontal fibroblasts. An improved understanding of the regulation and function of periodontal fibroblasts will be critical for the development of new therapies to optimize the restoration of periodontal structure and function after wounding.

Abstract
SummaryThe interaction of lipoprotein(a) [Lp(a)] with platelets is not well defined, particularly with regards to the individual contribution of the protein components of Lp(a), the apo B-100 and the apolipoprotein apo(a). This study investigated the binding of different recombinant apo(a) [r-apo(a)] isoforms, to human platelets and its effect on platelet aggregation. Scatchard analysis of saturation binding experiments demonstrated that human platelets display a single class of high affinity r-apo(a) binding sites (71 ± 46 molec./platelet, Kd = 5.6 ± 2.0 nmol/L). Platelet activation with strong agonists (thrombin, arachidonic acid) increased 2- to 10-fold the r-apo(a) binding, without affecting the affinity. Competition assays showed that the binding sites are highly specific for r-apo(a) and Lp(a). At high concentration t-PA could also bind to the r-apo(a) binding sites. By contrast, neither fibrinogen nor plasminogen inhibited to the r-apo(a) binding. The lysine analogue EACA inhibits the binding of r-apo(a) to platelets, thus suggesting the involvement of lysine residues in that interaction. Moreover, the r-apo(a) binding to platelets is unlikely mediated by GPIIb/IIIa-attached fibrin since it is not affected by platelet treatment with either LJ-CP8, a monoclonal antibody that specifically blocks fibrinogen binding to GPIIb/IIIa, nor GPRP, an inhibitor of fibrin polymerisation. Finally, we show that the distinct recombinant apo(a) proteins, as well as native Lp(a), promote an aggregation response of platelets to otherwise subaggregant doses of arachidonic acid. This proaggregant effect of r-apo(a) is dependent on its binding to platelets since it requires a minimum incubation time, and it is prevented by EACA at concentration inhibiting the r-apo(a)-platelet interaction.These results suggest that the prothrombotic action of Lp(a) may be in part mediated by modulating the platelet function through the interaction of its apo(a) subunit with a specific receptor at the platelet surface.

Abstract
SummaryThe platelet membrane glycoprotein (GP) Ibα plays a key role in the initial formation of thrombi. Polymorphisms (VNTR and HPA-2) in this receptor are associated with increased risk of coronary heart disease (CHD) and cerebral vascular disease (CVD). We investigated whether a recently described polymorphism (S/R), due to a single base change (T → C) five nucleotides upstream the initiator codon of GPIbα, might influence the expression of the protein, and be implicated in the development of arterial thrombosis.One hundred and thirty nine healthy individuals provided blood samples for DNA analysis of platelet GPIbα polymorphisms, and for flow cytometric analysis of the surface expression of the receptor. A group of 20 S/R normal individuals and an identical number of S/S participants, age and sex matched, was investigated for the analysis of the density of various platelet receptors. The distribution of the S/R polymorphism was also analyzed in two case/control studies including 104 CVD patients, 101 CHD patients, and one control age, sex, and environmental risk factors matched for each case patient. Surface density of GPIbα showed no wide variations between individuals, was not influenced by the presence of S or R alleles, nor associated with the VNTR or HPA-2 polymorphisms. The prevalence of the S/R genotype among CVD and CHD patients was not distinct from that in the control groups. We conclude that the S/R polymorphism of GPIbα, flanking the initiator codon of the receptor, does not seem to be associated with surface levels of the protein, and is not an independent risk factor for arterial thrombosis.

Abstract
Background Several health organizations have adopted the 5A’s brief intervention model (Ask, Advise, Assess, Assist, Arrange), based on evidence-based guidelines for smoking cessation. We examine individual, cognitive, behavioral, and organizational factors associated with the 5A’s performance among clinical healthcare workers in Catalonia. We also investigate how these factors interact and potentially predict the implementation of each component of the 5A’s. Methods A cross-sectional survey was conducted among clinical health workers enrolled in an online smoking cessation training course (n = 580). The survey included questions about individual characteristics as well as cognitive, behavioral, and organizational factors previously identified in research. We assessed self-reported performance of the 5A’s, assessed on a scale from 0 to 10, and used Multivariate regression to examine factors associated with its performance. Results The performance means (standard deviation) were moderate for the first 3A’s [Ask: 6.4 (3.1); Advise: 7.1 (2.7); Assess: 6.3 (2.8)] and low for the last 2A’s [Assist: 4.4 (2.9); Arrange: 3.2 (3.3)]. We observed a high correlation between Assist and Arrange (r = 0.704, p < 0.001). Having positive experiences and feeling competent were positively associated with performing the 5A’s model and having organizational support with Assist and Arrange. Personal tobacco use among healthcare workers was negatively associated with Advice and Arrange. Conclusions Our study found that clinical healthcare workers do not perform the 5A’s completely. The main barriers identified suggest the need of training and making available practical guidelines in healthcare services. Organizational support is essential for moving towards the implementation of Assist and Arrange.

Abstract
Zygosaccharomyces rouxii is the main spoilage yeast of grape juice concentrates. Detection and identification of Z. rouxii during the production of grape juice concentrate is critical to prevent spoilage in the final product. In this work, three grape juice concentrate processing plants were assessed by identifying osmophilic yeasts in juices and surfaces during different stages of a complete production line. Subsequently, molecular typing of Z. rouxii isolates was done to determine the strain distribution of this spoilage yeast. Osmotolerant yeast species, other than Z. rouxii, were mainly recovered from processing plant environments. Z. rouxii was only isolated from surface samples with grape juice remains. Z. rouxii was largely isolated from grape juice samples with some degree of concentration. Storage of grape juice pre-concentrate and concentrate allowed an increase in the Z. rouxii population. A widely distributed dominant molecular Z. rouxii pattern was found in samples from all three processing plants, suggesting resident microbes inside the plant.

Abstract
To determine the role of biomarkers in the clinical management of respiratory complications (RC) in hematopoietic stem cell transplantation (HSCT) recipients, we have prospectively evaluated a cohort of 175 patients followed-up for 1 year after HSCT. To avoid misinterpretation, we have excluded both unidentified respiratory infections (RI) and mixed RI. A total of 64 RC were included. Plasma levels of C-reactive protein (CRP), procalcitonin (PCT) and proadrenomedullin (proADM) were measured at diagnosis and on day 3 and 7. Different cytokines were evaluated in serum on the first day. No HSCT recipients without RC were included as a control group. Compared with RI, non-infectious RC showed a significant increase in CRP, proADM and interleukin 6 on day 0 (P=0.005; P=0.03 and P=0.04, respectively). When only RI were considered, we observed that bacterial–fungal PI showed higher levels of CRP (P=0.02), PCT (P=0.04) and proADM (P<0.01). Persistent low levels of proADM biomarkers suggest viral infection (specificity and positive predictive value 100%). Patients dying of RC had PCT and proADM levels higher than survivors (P=0.002 and P=0.03, respectively). In HSCT recipients biomarkers increase in both infectious and non-infectious RC. They may have utility in the assessment of the severity of RC and in suspecting a viral etiology.

Abstract
Changes in calcium bioaccessibility and sensory attributes of four different calcium compounds (calcium hydroxide lactate, emulsified calcium triphosphate, calcium pidolate and calcium amino acid chelate) added to a citric juice were studied at 0, 6 and 12 months of storage. Type of calcium compound showed significant differences ( p 0.05) in calcium bioaccessibility at the three periods of the study. The maximum value at month 0 and month 6 corresponded to the calcium amino acid chelate (45.09±0.59%) followed by calcium pidolate (38.09±0.28%), calcium lactate (32.4±2.17%) and calcium triphosphate (31.21±4.43%). There were no changes in calcium bioaccessibility through time of storage in any juice added with the different calcium salts, however organoleptic changes were critical in the most available samples at month 6. According to these results three of the salts (calcium hydroxide lactate, calcium pidolate and calcium triphosphate) were equally valid for adding to a citric fruit juice for up to 12 months of storage.

Abstract
OBJECTIVE To generate normative data for the Verbal Fluency Tests across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. METHOD The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the Verbal Fluency Test as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. RESULTS The final multiple linear regression models for the letter F explained 8-30% of the variance, 7-32% for letter A, 8-32% for the letter S, and 16-43% for the animal category in Verbal Fluency Test scores. Although t-tests showed significant differences between men and women on the Verbal Fluency Test, they did not have an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. CONCLUSIONS This is the first normative multicenter study conducted in Latin America aiming to create norms for the Verbal Fluency Test; this study will have important outcomes for the future of neuropsychology in the region.

Abstract
OBJECTIVE To generate normative data on the Stroop Test across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. METHOD The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the Stroop Test, as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. RESULTS The final multiple linear regression models explained 14-36% of the variance in Stroop Word scores, 12-41% of the variance in the Stoop Color, 14-36% of the variance in the Stroop Word-Color scores, and 4-15% of variance in Stroop Interference scores. Although t-tests showed significant differences between men and women on the Stroop test, none of the countries had an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. CONCLUSIONS This is the first normative multicenter study conducted in Latin America to create norms for the Stoop Test in a Spanish-Speaking sample. This study will therefore have important implications for the future of neuropsychology research and practice throughout the region.
