Diagnostic Validation of Anti-TOX Antibody for Early-Stage Mycosis Fungoides Through Digital Analysis of Tissue Samples.

ABSTRACT: Mycosis fungoides (MF) has become one of the most difficult diagnostic challenges for both dermatologists and dermatopathologists because its clinical presentation and microscopic findings may mimic benign reactive processes, specifically those displaying histopathological features of interface dermatitis. The goal of our study was to prove with digital scanning and automated sample methodology through algorithmic analysis, combined with the utility of TOX marker a more precise, faster, and objective evaluation of each sample. Moreover, this would offer high levels of reproducibility with the possibility of establishing cut-off points, allowing us to distinguish between inflammatory dermatoses (ID) and MF. A retrospective longitudinal-descriptive and observational study was conducted to compare the diagnostic criteria (immunohistochemical studies of anti-TOX stain) in patients with clinical suspicion of MF by dividing them into 2 groups: samples with a positive biopsy for MF (MF group) and those with a negative biopsy, therefore diagnosed as an ID (control group). The algorithm assessed 5 selected areas with lymphocytic representative cellularity, and based on the intensity, nuclear staining was classified as 0 (negative), 1+ (weak/yellow), 2+ (moderate/orange), and 3+ (strong/scarlet red) nuclei. The results showed statistically significant differences ( P = 0.040) between the mean number of (2+) nuclei in the positive final diagnosis group (MF group) and the negative final diagnosis group (ID group).

Is there interest of Mexican adults in being prepared should they develop Alzheimer's or other dementia? / ¿Existe interés en adultos mexicanos de preparase en caso de llegar a padecer Alzheimer u otra demencia?

Abstract Introduction Alzheimer's disease, as well as other dementias, cause a progressive deterioration of cognitive functions, preventing patients from making decisions and having control over themselves in an advanced stage of the disease. Objective To explore some expectations, wishes and preferences in a sample of mature adults should they develop Alzheimer or other dementia. Method We surveyed 368 mature Mexican adults without dementia using a large survey created by the authors and used in a previous study; data were collected in some public places where mature people were invited to participate. The survey was completed from July 2019 to August 2020. Results Although most participants had considered they might suffer from dementia in the future, less than half had communicated their wishes to their relatives about future medical treatments in case they could no longer decide for themselves; very few had prepared a written advance directive. Most participants agreed that patients should know their initial diagnosis, mainly to be able to prepare themselves. The main reason given by those who would prefer to hide the diagnosis was to avoid suffering. Discussion and conclusion Our results highlight the need for health professionals to promote discussion with people about the possibility of suffering from dementia, as well as the importance of making decisions in advance, and letting their relatives know about them.

Resumen Introducción La enfermedad de Alzheimer, así como las otras demencias, causan un deterioro progresivo de las funciones cognitivas, evitando que en una etapa avanzada de la enfermedad los pacientes puedan tomar decisiones y tener control sobre sí mismos. Objetivo Explorar algunas expectativas, deseos y preferencias en una muestra de adultos maduros en caso de que llegaran a desarrollar Alzheimer u otra demencia. Método Encuestamos a 368 adultos mexicanos maduros sin demencia usando una encuesta creada por los autores y utilizada en un estudio anterior; los datos se recopilaron en algunos lugares públicos donde se invitó a las personas a participar. La encuesta se aplicó de julio de 2019 a agosto de 2020. Resultados Aunque la mayoría de los participantes había considerado que podría sufrir demencia en el futuro, menos de la mitad había comunicado sus deseos a sus familiares sobre futuros tratamientos médicos en caso de que ya no pudieran decidir por sí mismos; muy pocos habían preparado una voluntad anticipada por escrito. La mayoría de los participantes estuvo de acuerdo en que los pacientes deben conocer su diagnóstico inicial, principalmente para poder prepararse. La principal razón aducida por quienes preferirían ocultar el diagnóstico fue el deseo de evitar sufrimiento. Discusión y conclusión Nuestros resultados destacan la necesidad de que el personal de salud promueva la discusión con las personas sobre la posibilidad de padecer demencia, así como la importancia de tomar decisiones por anticipado e informar de ellas a sus familiares.

TACkling Cancer by Targeting Selective Protein Degradation.

Targeted protein degradation has emerged as an alternative therapy against cancer, offering several advantages over traditional inhibitors. The new degrader drugs provide different therapeutic strategies: they could cross the phospholipid bilayer membrane by the addition of specific moieties to extracellular proteins. On the other hand, they could efficiently improve the degradation process by the generation of a ternary complex structure of an E3 ligase. Herein, we review the current trends in the use of TAC-based technologies (TACnologies), such as PROteolysis TArgeting Chimeras (PROTAC), PHOtochemically TArgeting Chimeras (PHOTAC), CLIck-formed Proteolysis TArgeting Chimeras (CLIPTAC), AUtophagy TArgeting Chimeras (AUTAC), AuTophagosome TEthering Compounds (ATTEC), LYsosome-TArgeting Chimeras (LYTAC), and DeUBiquitinase TArgeting Chimeras (DUBTAC), in experimental development and their progress towards clinical applications.

Clinicopathological Profiles Associated with Discordant RAS Mutational Status between Liquid and Tissue Biopsies in a Real-World Cohort of Metastatic Colorectal Cancer.

We aimed to identify common mCRC profiles associated with a discordant mutational status of RAS between the standard of care (SoC) tumour tissue tests and ctDNA tests to understand ctDNA detection and improve treatment responses. This was a multicentre, retrospective and prospective study. A total of 366 Spanish mCRC patients were independently recruited. BEAMing ddPCR technology was employed to detect ctDNA RAS mutations, and logistic regression analyses were performed to investigate clinicopathological factors associated with discordance. The highest concordance ratios were observed in profiles with multiple metastatic sites when the liver was present (89.7%; 95% CI 84.8-93.2), profiles with synchronous disease without primary tumour resection (90.2%; 95% CI 83.6-94.3) and profiles with mCRC originating in the left colon (91.3%; 95% CI 85.0-95.0). Metachronous disease originating in the right colon (OR = 6.1; 95% CI 1.7-26.5; p-value = 0.006) or rectum (OR = 5.0; 95% CI 1.5-17.8; p-value = 0.009) showed the highest probability of discrepancies. Primary tumour resection and a higher frequency of single metastases in the peritoneum or lungs in these patients were associated with reduced plasmatic mutation allele fractions (MAFs) and an increased probability of showing false-negative genotypes. Additional testing of patients with mCRC originating in the right colon or rectum with a single non-mutated ctDNA test is advised before the choice of therapy.

Procedural pain in patients with cancer: a Delphi expert management consensus.

OBJECTIVES: Diagnosis, treatment and care of cancer often involve procedures that may be distressing and potentially painful for patients. The PROCEDIO Study aimed to generate expert-based recommendations on the management of moderate to severe procedural pain in inpatients and outpatients with cancer. METHODS: Using a two-round Delphi method, experts from pain and palliative care units, medical and radiation oncology and haematology departments expressed their agreement on 24 statements using a 9-point Likert scale, which were classified as appropriate (median 7-9), uncertain (4-6) or inappropriate (1-3). Consensus was achieved if at least two-thirds of the panel scored within the range containing the median. RESULTS: With an overall agreement on the current definition of procedural pain, participants suggested a wider description based on evidence and their clinical experience. A strong consensus was achieved regarding the need for a comprehensive pre-procedural pain assessment and experts emphasised that healthcare professionals involved in procedural pain management should be adequately trained. Most panellists (98.2%) agreed that pharmacological treatment should be chosen considering the duration of the procedure. Transmucosal fentanyl (96.5%) and morphine (71.7%) were recommended as the most appropriate drugs. Oral and nasal transmucosal fentanyl were agreed as the most suitable for both outpatients and inpatients, while consensus was reached for intravenous and subcutaneous morphine for inpatients. CONCLUSIONS: These results provide updated expert-based recommendations on the definition, prevention and treatment of moderate to severe procedural pain, which could inform specialists involved in pain management of patients with cancer.

One-year longitudinal association between changes in dietary choline or betaine intake and cardiometabolic variables in the PREvención con DIeta MEDiterránea-Plus (PREDIMED-Plus) trial.

BACKGROUND: Choline and betaine intakes have been related to cardiovascular health. OBJECTIVES: We aimed to explore the relation between 1-y changes in dietary intake of choline or betaine and 1-y changes in cardiometabolic and renal function traits within the frame of the PREDIMED (PREvención con DIeta MEDiterránea)-Plus trial. METHODS: We used baseline and 1-y follow-up data from 5613 participants (48.2% female and 51.8% male; mean ± SD age: 65.01 ± 4.91 y) to assess cardiometabolic traits, and 3367 participants to assess renal function, of the Spanish PREDIMED-Plus trial. Participants met ≥3 criteria of metabolic syndrome and had overweight or obesity [BMI (in kg/m2) ≥27 and ≤40]. These criteria were similar to those of the PREDIMED parent study. Dietary intakes of choline and betaine were estimated from the FFQ. RESULTS: The greatest 1-y increase in dietary choline or betaine intake (quartile 4) was associated with improved serum glucose concentrations (-3.39 and -2.72 mg/dL for choline and betaine, respectively) and HbA1c levels (-0.10% for quartile 4 of either choline or betaine intake increase). Other significant changes associated with the greatest increase in choline or betaine intake were reduced body weight (-2.93 and -2.78 kg, respectively), BMI (-1.05 and -0.99, respectively), waist circumference (-3.37 and -3.26 cm, respectively), total cholesterol (-4.74 and -4.52 mg/dL, respectively), and LDL cholesterol (-4.30 and -4.16 mg/dL, respectively). Urine creatinine was reduced in quartile 4 of 1-y increase in choline or betaine intake (-5.42 and -5.74 mg/dL, respectively). CONCLUSIONS: Increases in dietary choline or betaine intakes were longitudinally related to improvements in cardiometabolic parameters. Markers of renal function were also slightly improved, and they require further investigation.This trial was registered at https://www.isrctn.com/ as ISRCTN89898870.

The Effect of Sex and Obesity on the Gene Expression of Lipid Flippases in Adipose Tissue.

Molecular mechanisms behind obesity and sex-related effects in adipose tissue remain elusive. During adipocyte expansion, adipocytes undergo drastic remodelling of lipid membrane compositions. Lipid flippases catalyse phospholipid translocation from exoplasmic to the cytoplasmic leaflet of membranes. The present study aimed to analyse the effect of sex, obesity, and their interactions on the gene expression of two lipid flippases-ATP8A1 and ATP8B1-and their possible microRNA (miR) modulators in visceral adipose tissue (VAT). In total, 12 normal-weight subjects (5 premenopausal women and 7 men) and 13 morbidly obese patients (7 premenopausal women and 6 men) were submitted to surgery, and VAT samples were obtained. Gene expression levels of ATP8A1, ATP8B1, miR-548b-5p, and miR-4643 were measured in VAT. Our results showed a marked influence of obesity on VAT ATP8A1 and ATP8B1, although the effects of obesity were stronger in men for ATP8A1. Both genes positively correlated with obesity and metabolic markers. Furthermore, ATP8B1 was positively associated with miR-548b-5p and negatively associated with miR-4643. Both miRs were also affected by sex. Thus, lipid flippases are altered by obesity in VAT in a sex-specific manner. Our study provides a better understanding of the sex-specific molecular mechanisms underlying obesity, which may contribute to the development of sex-based precision medicine.

Antitumoral Activity of a CDK9 PROTAC Compound in HER2-Positive Breast Cancer.

Cyclin-dependent kinases (CDKs) are a broad family of proteins involved in the cell cycle and transcriptional regulation. In this article, we explore the antitumoral activity of a novel proteolysis-targeting chimera (PROTAC) compound against CDK9. Breast cancer cell lines from different subtypes were used. Transcriptomic mapping of CDKs in breast cancer demonstrated that the expression of CDK9 predicted a detrimental outcome in basal-like tumors (HR = 1.51, CI = 1.08-2.11, p = 0.015) and, particularly, in the luminal B subtype with HER2+ expression (HR = 1.82, CI = 1.17-2.82, p = 0.0069). The novel CDK9 PROTAC, THAL-SNS-032, displayed a profound inhibitory activity in MCF7, T47D, and BT474 cells, with less effect in SKBR3, HCC1569, HCC1954, MDA-MB-231, HS578T, and BT549 cells. The three cell lines with HER2 overexpression and no presence of ER, SKBR3, HCC1569, and HCC1954 displayed an EC50 three times higher compared to ER-positive and dual ER/HER2-positive cell lines. BT474-derived trastuzumab-resistant cell lines displayed a particular sensitivity to THAL-SNS-032. Western blot analyses showed that THAL-SNS-032 caused a decrease in CDK9 levels in BT474, BT474-RH, and BT474-TDM1R cells, and a significant increase in apoptosis. Experiments in animals demonstrated an inverse therapeutic index of THAL-SNS-032, with doses in the nontherapeutic and toxic range. The identified toxicity was mainly due to an on-target off-tumor effect of the compound in the gastrointestinal epithelium. In summary, the potent and efficient antitumoral properties of the CDK9 PROTAC THAL-SNS-032 opens the possibility of using this type of compound in breast cancer only if specifically delivered to cancer cells, particularly in ER/HER2-positive and HER2-resistant tumors.

Recovery of polyclonal immunoglobulins during treatment in patients ineligible for autologous stem-cell transplantation is a prognostic marker of longer progression-free survival and overall survival.

Immunoparesis is the suppression of normal polyclonal immunoglobulins and is present in most patients with newly diagnosed multiple myeloma (MM). The association of immunoparesis at diagnosis, and particularly its recovery along with treatment, with survival in patients ineligible for autologous stem-cell transplantation (ASCT) has not been well established. This retrospective study evaluated the impact of immunoparesis in 431 patients diagnosed with MM, ineligible for ASCT, with a median overall survival of 36 months [95% confidence interval (CI): 31-40]. Immunoparesis was present in 81.2% of patients at diagnosis and was associated with a trend to a worse overall response rate (ORR: 84.8% vs. 74.9%; OR 1.88 (95% CI: 0.97-3.63), shorter progression-free survival (PFS) [22.0 vs. 18.2 months; hazard ratio (HR) 0.775; 95%CI: 0.590-1.018; p = 0.066], and overall survival (OS) (45.9 vs. 34.2 months; HR 0.746; 95% CI: 0.551-1.010; p = 0.057). Twenty-four per cent of patients who had immunoparesis at diagnosis recovered polyclonal immunoglobulins in the follow-up period. Interestingly, these patients had a better ORR (96.3% vs. 68.2%; OR 12.29 (95% CI: 3.77-40.06), PFS (HR 0.703; 95CI%: 0.526-0.941; p = 0.018) and OS (HR 0.678; 95 CI%: 0.503-0.913; p = 0.011) than patients who did not recover it. In summary, restoring a healthy immune system along with first-line treatment in patients with MM, not receiving ASCT, is associated with better outcomes.

Comparison of Colorectal Cancer Stem Cells and Oxaliplatin-Resistant Cells Unveils Functional Similarities.

Colorectal cancer is the second most common cancer in women, the third in men, and an important cause of cancer-related mortality. Recurrence and the development of chemotherapy resistance are major hindrances for patients' treatment. The presence of cancer stem cells with chemotherapy resistance able to generate proliferating tumor cells contributes to tumor recurrence and resistance. In addition, tumor cells can develop chemoresistance through adaptation mechanisms. In this article, cancer stem cells were isolated from HT29 and SW620 colorectal cancer cell lines. Oxaliplatin resistance was induced by a single drug treatment simulating the usual guidelines of patient treatment. A comparison of these two populations showed similarities since cancer stem cells presented increased oxaliplatin resistance, and resistant cells contained an increased number of cancer stem cells. Cancer stem cells isolated from resistant cells showed increased oxaliplatin resistance. Cell invasion capacity and epithelial-mesenchymal transition were increased both in cancer stem cells and oxaliplatin-resistant cells. mRNA expression analysis showed that both cell types shared a significant proportion of commonly regulated genes. In summary, the data presented indicate that colorectal cancer stem cells and oxaliplatin-resistant cells are highly related cell populations that might have interesting implications in the development of tumor recurrence and resistance to chemotherapy.

Predominó una higiene bucal regular en la población estudiada antes de iniciar el tratamiento y después de instalar los aparatos, de manera similar en los grupos con aparatos removibles, funcionales y fijos. Conclusiones: los pacientes de la población estudiada necesitan educación para apropiarse de conocimientos suficientes para mantener actitudes, prácticas e higiene bucal saludables.

ABSTRACT Background: adequate oral hygiene is necessary in patients who wear orthodontic appliances. Objective: to identify knowledge, attitudes, practices and oral hygiene in patients with orthodontic appliances. Methods: a study with a non-experimental, descriptive and cross-sectional design was carried out in the Provincial Teaching Dentistry Clinic of Sancti Spíritus in the period between September 2018 and July 2019. Methods from the theoretical, empirical (survey, interview and observation) and statistical level were used. The population consisted of 30 patients from this institution with orthodontic treatment. The measured variables were: age and sex of the patient, type of orthodontic appliance, level of knowledge about oral health, attitude and oral hygiene practices of the patient, frequency, form and efficiency of tooth brushing, as well as brushing or not after the ingestion of sugary foods. Results: 100% of the patients presented poor knowledge about oral health and unfavorable practices, although favorable attitudes were found in 63.3% of the patients. Regular oral hygiene predominated in the population studied before starting treatment and after installing the appliances, similarly in the groups with removable, functional and fixed appliances. Conclusions: the studied population patients need education to acquire sufficient knowledge to maintain healthy attitudes, practices and oral hygiene.

Clonal evolution of Candida albicans, Candida glabrata and Candida dubliniensis at oral niche level in health and disease.

Background: Candida species have long been recognised as aetiological agents of opportunistic infections of the oral mucosa, and more recently, as players of polymicrobial interactions driving caries, periodontitis and oral carcinogenesis. Methods: We studied the clonal structure of Candida spp. at oral niche resolution in patients (n = 20) with a range of oral health profiles over 22 months. Colonies from oral micro-environments were examined with multilocus sequencing typing. Results: Candida spp. identified were C. albicans, C. glabrata and C. dubliniensis. Increased propensity for micro-variations giving rise to multiple diploid strain types (DST), as a result of loss of heterozygosity, was observed among C. albicans clade 1 isolates compared to other clades. Micro-variations among isolates were also observed in C. dubliniensis contra to expectations of stable population structures for this species. Multiple sequence types were retrieved from patients without clinical evidence of oral candidosis, while single sequence types were isolated from oral candidosis patients. Conclusion: This is the first study to describe the clonal population structure, persistence and stability of Candida spp. at oral niche level. Future research investigating links between Candida spp. clonality and oral disease should recognise the propensity to micro-variations amongst oral niches in C. albicans and C. dubliniensis identified here.

GSE4-loaded nanoparticles a potential therapy for lung fibrosis that enhances pneumocyte growth, reduces apoptosis and DNA damage.

Idiopathic pulmonary fibrosis is a lethal lung fibrotic disease, associated with aging with a mean survival of 2-5 years and no curative treatment. The GSE4 peptide is able to rescue cells from senescence, DNA and oxidative damage, inflammation, and induces telomerase activity. Here, we investigated the protective effect of GSE4 expression in vitro in rat alveolar epithelial cells (AECs), and in vivo in a bleomycin model of lung fibrosis. Bleomycin-injured rat AECs, expressing GSE4 or treated with GSE4-PLGA/PEI nanoparticles showed an increase of telomerase activity, decreased DNA damage, and decreased expression of IL6 and cleaved-caspase 3. In addition, these cells showed an inhibition in expression of fibrotic markers induced by TGF-ß such as collagen-I and III among others. Furthermore, treatment with GSE4-PLGA/PEI nanoparticles in a rat model of bleomycin-induced fibrosis, increased telomerase activity and decreased DNA damage in proSP-C cells. Both in preventive and therapeutic protocols GSE4-PLGA/PEI nanoparticles prevented and attenuated lung damage monitored by SPECT-CT and inhibited collagen deposition. Lungs of rats treated with bleomycin and GSE4-PLGA/PEI nanoparticles showed reduced expression of α-SMA and pro-inflammatory cytokines, increased number of pro-SPC-multicellular structures and increased DNA synthesis in proSP-C cells, indicating therapeutic efficacy of GSE4-nanoparticles in experimental lung fibrosis and a possible curative treatment for lung fibrotic patients.

Result: the prevalence of periodontal disease as a cardiovascular risk factor is 48% (19 people) with chronically moderate and advanced generalized periodontitis. Conclusion: Based on the bibliographical review people with the degree of chronic periodontitis moderate and advanced generalized are prone to trigger a cardiovascular disease (acute myocardial infarction). However, more studies of longitudinal experimentation are necessary, based on the link which has the periodontal and cardiovascular disease (AU)

Graft infusion of adipose-derived mesenchymal stromal cells to prevent rejection in experimental intestinal transplantation: A feasibility study.

BACKGROUND: Mesenchymal stromal cells (MSC) have been proposed as a promising complement to standard immunosuppression in solid organ transplantation because of their immunomodulatory properties. The present work addresses the role of adipose-derived MSC (Ad-MSC) in an experimental model of acute rejection in small bowel transplantation (SBT). MATERIAL/METHODS: Heterotopic allogeneic SBT was performed. A single dose of 1.5x106 Ad-MSC was intra-arterially delivered just before graft reperfusion. Animals were divided into CONTROL (CTRL), CONTROL+Ad-MSC (CTRL_MSC), tacrolimus (TAC), and TAC+Ad-MSC (TAC_MSC) groups. Each Ad-MSC groups was subdivided in autologous and allogeneic third-party groups. RESULTS: Rejection rate and severity were similar in MSC-treated and untreated animals. CTRL_MSC animals showed a decrease in macrophages, T-cell (CD4, CD8, and Foxp3 subsets) and B-cell counts in the graft compared with CTRL, this decrease was attenuated in TAC_MSC animals. Pro- and anti-inflammatory cytokines and some chemokines and growth factors increased in CTRL_MSC animals, especially in the allogeneic group, whereas milder changes were seen in the TAC groups. CONCLUSION: Ad-MSC did not prevent rejection when administered just before reperfusion. However, they showed immunomodulatory effects that could be relevant for a longer-term outcome. Interference between tacrolimus and the MSC effects should be addressed in further studies.

Acute Brain Stroke Evolution Detected by 18F-FDG PET/CT and MRI Justifies the Discordance of Lesions in a Patient With Lymphoproliferative Syndrome.

ABSTRACT: A 50-year-old man with angioimmunoblastic T-cell lymphoma in complete response to treatment presented new hypermetabolic brain lesions on 18F-FDG PET/CT suggestive of malignancy. These findings were correlated by MRI that showed cortical-subcortical peripheral lesions typical of acute ischemic infarction. A restaging 18F-FDG PET/CT showed that hypermetabolic lesions were replaced by ametabolic areas, supporting chronic infarction. Early ischemia presents transitory FDG increase. Brain lymphomas are highly FDG avid and difficult to differentiate from acute cerebral infarction. In view of the discordance of abnormal areas of intracranial uptake on PET FDG, MRI confirmation is required to avoid misinterpretation.

Specific Quality of Life Assessment by the NutriQoL® Questionnaire Among Patients Receiving Home Enteral Nutrition.

BACKGROUND: Home enteral nutrition (HEN), including tube feeding and oral supplementation, can improve or worsen quality of life (QoL). The specific assessment of factors affecting QoL may identify the inherent problems associated with HEN. The aim of this study was to evaluate whether the validated NutriQoL® questionnaire is useful for assessing the QoL and the factors influencing it in patients receiving HEN. METHODS: A total of 78 patients receiving HEN completed both the NutriQoL and the SF-12 questionnaires during their routine visits to nutrition service at the hospital. RESULTS: Ninety percent of patients receiving HEN had cancer, 58% received oral supplements, and 42% received tube feeding. At recruitment, the mean score ± SD of the NutriQoL was 66 ± 14, whereas that of the SF-12 was 40 ± 9. A positive correlation between NutriQoL and SF-12 scores (ρ = 0.5; P < .001) was found. Multivariate analysis showed that HEN type (oral vs tube) (odds ratio [OR], 5.6; 95% CI 2.0-15.3; P = .001) and the absence of secondary effects (OR, 3.0; 95% CI, 1.2-7.9; P = .024) were both variables explaining NutriQoL results adjusted by sex and age. The SF-12 results did not show associations with nutrition factors. On visit 2, we observed significant improvements in NutriQoL results. CONCLUSION: The NutriQoL questionnaire identifies specific problems that affect the QoL of patients receiving HEN, whereas SF-12 does not. The route of entry and the occurrence of complications influence specific QoL. NutriQoL is a useful tool to identify the factors that worsen the QoL in patients receiving HEN.

Related cardiometabolic factors and prevalence of low HDL-cholesterol levels and atherogenic dyslipidemia. SIMETAP-AD study. / Factores cardiometabólicos asociados y prevalencia de concentraciones bajas de colesterol HDL y de dislipidemia aterogénica. Estudio SIMETAP-DA.

AIM: To determine the crude and sex- and age-adjusted prevalence rates of atherogenic dyslipidemia (AD) and low HDL-cholesterol levels (low-HDLc), and to assess their associations with cardiovascular risk factors, chronic kidney disease, cardiovascular and cardiometabolic diseases. METHODS: Population-based cross-sectional study conducted in Primary Care, with randomly selected adult subjects. The AD was considered if the patients had hypertriglyceridemia (triglycerides≥150mg/dL) and low-HDLc (<40mg/dL [men];<50mg/dL [women]). Crude and sex- and age-adjusted prevalence rates were determined, and univariate and multivariate analysis were performed to assess related cardiometabolic factors. RESULTS: Study population with 6,588 adults (55.9% women) with mean age 55.1 (±17.5) years. The mean HDLc levels were 49.2 (±12.6) mg/dL in men and 59.2 (±14.7) mg/dL in women. The crude prevalence rates of low-HDLc and AD were 30.8% (95%CI: 29.7-31.9), and 14.3% (95%CI: 13.5-15.2), respectively. The adjusted prevalence rates of low-HDLc were 28.0% in men and 31.0% in women, and AD were 16.4% in men and 10.6% in women. Seventy-three percent of the population with AD had high or very high cardiovascular risk. The independent factors associated with low HDLc or with AD were diabetes, smoking, abdominal obesity, and obesity. The major factors associated with low HDLc and AD were hypertriglyceridemia and diabetes, respectively. CONCLUSIONS: Almost a third of the adult population had low HDL-C and half of them met AD criteria. Cardiometabolic factors were associated with low HDL-C and AD, highlighting hypertriglyceridemia with low HDLc, and DM with AD.

Quality of life in patients with breakthrough cancer pain in radiation oncology departments in Spain: the CAVIDIOR study.

Aim: The CAVIDIOR study evaluated quality of life (QoL) in patients with breakthrough cancer pain receiving palliative radiation therapy in radiation oncology departments (RODs) in Spain. Patients & methods: Prospective observational study at 11 Spanish RODs (July 2016-November 2017). QoL was assessed using Short Form Health Survey 12. Secondary end points were sleep quality, caregiver burden and patient/perception of improvement. Results: QoL improved according to the Short Form Health Survey 12 mental component.
