[Health service needs of migrant women from a basic health area: A qualitative study]. / Necesidades sentidas de salud en mujeres migrantes de una zona básica de salud: estudio cualitativo.

OBJECTIVES: To know the needs and lack of information on health issues of Maghrebi women. SUBJECTS, MATERIAL AND METHOD: Design: Qualitative study technique nominal group (TGN). SUBJECTS: 14 North African women from Association for Solidarity and Rapprochement of Cultures (ASAC) from the rural clinic of La Aljorra who knew and understood Spanish, older age, and lived in the town for more than 3 years. Material and method TGN asks: «What daily health issues for you and your family worry you the most and do you need answers?¼ Individual reflection and list that were discussed among them, joining the group consensus. Subsequently, they were prioritized individually and a definitive list of their prioritized health needs was made. RESULTS: Thirty-six percent of the ASAC associates attended. At first, 17 topics were written on health needs for which they wanted a response. The final topics chosen and grouped by them were 6: 1) Contraceptive methods; 2) Relationship problems; 3) Thyroid; 4) How to cure the sciatic nerve?; 5) Anemia and 6) Stress. 70% related to the area of sexuality. CONCLUSIONS: 1) Qualitative research is an adequate consensus method to obtain information on little-known topics and directly from the person involved; 2) The Moroccan migrant woman considers information about sexuality and couple relationships very important; 3) Another pathology unknown to them and emerging in the area is thyroid; 4) Stress and its repercussions; 5) Sciatica and its consequences are also important when being agricultural workers.

Variants rs2758346, rs5746094, and rs2758331 of SOD2 gene: association study with breast cancer in a Mexican population and their analysis in silico.

OBJECTIVE: The aim of the study was to analyze the association between the superoxide dismutase 2 (SOD2) gene variants rs2758346, rs5746094, and rs2758331 and breast cancer (BC) in the Mexican population as well as to perform in silico assessments of the variants' potential impact. PATIENTS AND METHODS: We performed in silico analysis and analyzed 489 healthy women and 467 BC patients using TaqMan assays and Real-Time PCR. RESULTS: The TT genotype, the T allele of the rs2758346 variant, and the CC genotype of both rs5746094 and rs2758331 were identified as BC risk factors (p < 0.05). The TT and CTTT genotype of the rs2758346 variant stratified by the presence of ki-67 (> 20%), TCCC, and estrogen receptor (ER)-positive of the rs5746094 variant, and the CC and CT genotypes of rs2758331 stratified by menopause status and non-chemotherapy response were risk factors. The TTC and TTA haplotypes are risk factors for BC. In silico analysis revealed that the rs2758346, rs5746094, and rs2758331 variants could influence SOD2 gene regulation by transcription factors and circulating RNAs (circRNAs). CONCLUSIONS: The rs2758346, rs5746094, and rs2758331 variants of the SOD2 gene were associated with BC risk and could influence SOD2 regulation by transcription factors and circRNAs.

Association of adiposity and its changes over time with COVID-19 risk in older adults with overweight/obesity and metabolic syndrome: a longitudinal evaluation in the PREDIMED-Plus cohort.

BACKGROUND: Cross-sectionally, older age and obesity are associated with increased coronavirus disease-2019 (COVID-19) risk. We assessed the longitudinal associations of baseline and changes in adiposity parameters with COVID-19 incidence in older adults at high cardiovascular risk. METHODS: This analysis included 6874 men and women (aged 55-75 years) with overweight/obesity and metabolic syndrome in the PREDIMED-Plus lifestyle intervention trial for cardiovascular risk reduction. Body weight, body-mass-index (BMI), waist circumference, waist-to-height ratio (WHtR), and a body shape index (ABSI) were measured at baseline and annual follow-up visits. COVID-19 was ascertained by an independent Event Committee until 31 December 2021. Cox regression models were fitted to evaluate the risk of COVID-19 incidence based on baseline adiposity parameters measured 5-6 years before the pandemic and their changes at the visit prior to censoring. RESULTS: At the time of censoring, 653 incident COVID-19 cases occurred. Higher baseline body weight, BMI, waist circumference, and WHtR were associated with increased COVID-19 risk. During the follow-up, every unit increase in body weight (HRadj (95%CI): 1.01 (1.00, 1.03)) and BMI (HRadj: 1.04 (1.003, 1.08)) was associated with increased COVID-19 risk. CONCLUSIONS: In older adults with overweight/obesity, clinically significant weight loss may protect against COVID-19. TRIAL REGISTRATION: This study is registered at the International Standard Randomized Controlled Trial (ISRCT; http://www.isrctn.com/ISRCTN89898870 ).

Usage of immersive virtual reality as a relaxation method in an intensive care unit.

INTRODUCTION: The usage of immersive virtual reality (iVR) in the context of an intensive care unit (ICU) is scarce. Our objective was to assess the feasibility of the usage of iVR in critical patients with or without mechanical ventilation (MV) and to determine the anxiety degree before and after each session. METHODS: Analytical, descriptive, prospective, and cross-sectional research. Pilot test with 20 patients from a polyvalent ICU of a tertiary hospital. Adult patients were included, either connected or not to MV, watchful and calmed (RASS -1/+1) and without delirium (negative CAM-ICU). Oculus Go (Facebook Technologies, LLC) iVR glasses were the model used. The relaxation strategy consisted in the visualization of an experience of 15 min with scenes related to nature and fantasy, relaxing music with a plot. The sessions were individual, with the patient monitored in a fowler position or seated. The anxiety degree before and after each session was evaluated following a reduced version of the Spanish "Cuestionario de Ansiedad Estado-Rasgo (STAI-e)" and they were analysed using T samples coupled (statistical significance when p-value was <0.05). RESULTS: Incorporation of 20 patients with an average age of 63.9 years old (60% men). A total of 34 sessions of iVR were conducted. 32% patients mechanically ventilated, 32% high-flow oxygen therapy, 36% other breathing supports. 80% of the sessions were completed without serious side effects. A significant decrease in the anxiety degree was observed after each iVR session: first session mean change -2.68 (SD = 2.75), p = 0.000; second session mean change -1.86 (SD = 1.57), p = 0.021; third session mean change -1.67 (SD = 1.63), p = 0.054. CONCLUSION: The usage of iVR in the context of an ICU is feasible, even with patients mechanically ventilated. iVR reduces the anxiety degree in the critic patient, which suggests that "digital therapies" can be effective to improve the emotional state during their stay in the ICU.

A systematic review on machine learning approaches in the diagnosis and prognosis of rare genetic diseases.

BACKGROUND: The diagnosis of rare genetic diseases is often challenging due to the complexity of the genetic underpinnings of these conditions and the limited availability of diagnostic tools. Machine learning (ML) algorithms have the potential to improve the accuracy and speed of diagnosis by analyzing large amounts of genomic data and identifying complex multiallelic patterns that may be associated with specific diseases. In this systematic review, we aimed to identify the methodological trends and the ML application areas in rare genetic diseases. METHODS: We performed a systematic review of the literature following the PRISMA guidelines to search studies that used ML approaches to enhance the diagnosis of rare genetic diseases. Studies that used DNA-based sequencing data and a variety of ML algorithms were included, summarized, and analyzed using bibliometric methods, visualization tools, and a feature co-occurrence analysis. FINDINGS: Our search identified 22 studies that met the inclusion criteria. We found that exome sequencing was the most frequently used sequencing technology (59%), and rare neoplastic diseases were the most prevalent disease scenario (59%). In rare neoplasms, the most frequent applications of ML models were the differential diagnosis or stratification of patients (38.5%) and the identification of somatic mutations (30.8%). In other rare diseases, the most frequent goals were the prioritization of rare variants or genes (55.5%) and the identification of biallelic or digenic inheritance (33.3%). The most employed method was the random forest algorithm (54.5%). In addition, the features of the datasets needed for training these algorithms were distinctive depending on the goal pursued, including the mutational load in each gene for the differential diagnosis of patients, or the combination of genotype features and sequence-derived features (such as GC-content) for the identification of somatic mutations. CONCLUSIONS: ML algorithms based on sequencing data are mainly used for the diagnosis of rare neoplastic diseases, with random forest being the most common approach. We identified key features in the datasets used for training these ML models according to the objective pursued. These features can support the development of future ML models in the diagnosis of rare genetic diseases.

SOD1 gene variants rs4817415, rs2070424, and rs1041740 and their association with breast cancer risk.

OBJECTIVE: The aim of this investigation was to determine the frequency and association of the variants rs4817415, rs2070424, and rs1041740 of the SOD1 gene in healthy women and breast cancer (BC) patients. PATIENTS AND METHODS: Genomic DNA samples from 146 healthy women and 130 patients with BC were analyzed. RESULTS: GG genotype (OR 2.54, 95% CI 1.31-4.91, p = 0.0073) and the G allele (OR 1.37, 95% CI 1.09-1.73, p = 0.007) of the rs2070424 variant and CC genotype (OR 1.67, 95% CI 1.04-0.2.70, p = 0.0444) and allele C (OR 1.58, 95% CI 1.09-2.29, p = 0.0183) of the rs1041740 variant of SOD1 gene were associated as risk factors for BC susceptibility relative to the control group. Study groups comparison of the stratification by menopausal status showed an association of susceptibility to BC risk with carriers of the GG genotype (OR 2.9, 95% CI 1.11-7.81, p = 0.042) of the rs2070424 variant and with the premenopausal status of the study group and the TT (OR 2.89, 95% CI 1.73-4.85, p = 0.001) genotype of the rs1041740 variant. Furthermore, differences were observed in the patients with BC who were carriers of the CC genotype of the rs4817415 variant with elevated Ki-67 (≥ 20%) and who presented lymph node metastasis and stage III-IV BC (p<0.05). Two common haplotypes were identified in the study groups: CAC (protective factor), and CGC (risk factor) (p<0.05). CONCLUSIONS: The rs2070424 and rs1041740 variants of the SOD1 gene and the CGC haplotype were associated as risk susceptibility factors of BC in this sample analyzed.

[Validity and usefulness of the RAE-CMBD studying patients hospitalised with influenza]. / Validez y utilidad del RAE-CMBD en el estudio de los pacientes hospitalizados con gripe.

OBJECTIVE: Understanding the hospital impact of influenza requires enriching epidemiological surveillance registries with other sources of information. The aim of this study was to determine the validity of the Hospital Care Activity Record - Minimum Basic Data Set (RAE-CMBD) in the analysis of the outcomes of patients hospitalised with this infection. METHODS: Observational and retrospective study of adults admitted with influenza in a tertiary hospital during the 2017/2018 and 2018/2019 seasons. We calculated the concordance of the RAE-CMBD with the influenza epidemiological surveillance registry (gold standard), as well as the main parameters of internal and external validity. Logistic regression models were used for risk adjustment of in-hospital mortality and length of stay. RESULTS: A total of 907 (97.74%) unique matches were achieved, with high inter-observer agreement (ƙ=0.828). The RAE-CMBD showed a 79.87% sensitivity, 99.72% specificity, 86.71% positive predictive value and 99.54% negative predictive value. The risk-adjusted mortality ratio of patients with influenza was lower than that of patients without influenza: 0.667 (0.53-0.82) vs. 1.008 (0.98-1.04) and the risk-adjusted length of stay ratio was higher: 1.15 (1.12-1.18) vs. 1.00 (0.996-1.001). CONCLUSIONS: The RAE-CMBD is a valid source of information for the study of the impact of influenza on hospital care. The lower risk-adjusted mortality of patients admitted with influenza compared to other inpatients seems to point to the effectiveness of the main clinical and organisational measures adopted.

Antecedentes y objetivo: El objetivo de este estudio fue determinar las complicaciones de la gripe en todos los adultos hospitalizados con esta enfermedad y, de forma específica, analizar las características de los eventos cardiovasculares posinfección.Metodología: Estudio observacional y descriptivo de los episodios de gripe en adultos hospitalizados durante las temporadas 2017-2018 y 2018-2019, utilizando el registro específico de un hospital terciario. Las complicaciones analizadas fueron: neumonía, fallo multiorgánico, shock séptico, síndrome de distrés respiratorio agudo y eventos cardíacos.Resultados: Un total de 928 adultos con gripe precisaron hospitalización, de los que 303 (32,7%) presentaron una o más complicaciones. El 2,5% de los pacientes sufrieron un evento cardíaco posgripe, con mayor probabilidad de ingreso en la UCI y mayor mortalidad. La vacunación antigripal fue un factor protector del evento cardíaco (OR: 0,32; IC 95%: 0,13-0,83).Conclusiones: La gripe presenta importantes complicaciones en los pacientes hospitalizados. La elevada mortalidad de los eventos cardíacos posinfección implica acentuar las medidas preventivas, destacando la vacunación antigripal anual. (AU)

Background and aims: The aim of this study was to determine the complications of influenza in all adults hospitalized with this disease and, specifically, to analyze the characteristics of post-infection cardiovascular events.Methods: Observational and descriptive study of adults hospitalized with influenza during the 2017-2018 and 2018-2019 seasons using the specific registry of a tertiary hospital. The complications analyzed were pneumonia, multiple organ dysfunction syndrome, septic shock, acute respiratory distress syndrome, and cardiac events.Results: A total of 928 adults with influenza required hospitalization and 303 (32.7%) presented with one or more complications. A post-influenza cardiac event occurred in 2.5% of patients; they had a higher probability of ICU admission and higher mortality. Influenza vaccination was a protective factor for cardiac events (OR 0.32; 95%CI 0.13-0.83).Conclusions: Influenza can lead to important complications in hospitalized patients. The high mortality rate associated with post-infection cardiac events means that preventive measures, including annual influenza vaccination, need to be emphasized. (AU)

Mutational spectrum of the iduronate-2-sulfatase gene in Mexican patients with Hunter syndrome.

OBJECTIVE: Hunter syndrome, or mucopolysaccharidosis type II (MPS II), is caused by deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS), which is responsible for degrading heparan and dermatan sulfate. The IDS gene is located on chromosome Xq28; pathological variants in this gene mostly consist of missense mutations and small and larger deletions, which produce different phenotypes. However, there is only one record in our population concerning the molecular mechanism of this disease; a genotype-phenotype description is not available. PATIENTS AND METHODS: There were included 24 unrelated male patients; clinical features were recorded at a database, fluorometric IDS enzyme activity testing was done for each individual, followed by Sanger sequencing to identify mutations. RESULTS: The mutational spectrum was found in 16 out of 24 Mexican patients with MPS II, and its range of phenotypes was described. The most frequent variants were of the missense type. The most affected exons were exon 3 (c.275T>G, c.284_287del, c.325T>C), exon 8 (c.1035G>C, c.550G>A), exon 9 (c.1403G>C, c.1229_1229del), and exon 7 (c.979A>C; this variant has not been previously reported). Exon 5 (c.438C>T, a non-pathogenic variant) was the least frequent. It was also found that the most severely affected patients were those with large deletions (2 out of 24) [rsaIDS: IDSP1 (P164)x0, FMR1, AFF2 (P164)x2] involving genes and pseudogenes. We found 2 patients with a synonymous mutation in exon 4. CONCLUSIONS: Our results confirmed reports in the literature, since the most frequent variants were reported in exons 3 and 8. However, this result varies from one previous report in our population, which mentions large deletions and rearrangements as the most frequent alterations, since complex rearrangements were not found. According to what has been previously found, the most severely affected patients are those in which a whole gene has been deleted.

Aplicación de la técnica OFA en cirugía mayor. Experiencia en un hospital secundario / OFA in major surgery. Experience at a secondary level hospital

Introducción: La técnica OFA (opioid free anaesthesia) se basa en una anestesia multimodal con menor uso de opioides, que consigue un adecuado control del dolor, con menor incidencias de náuseas y vómitos en el postoperatorio y mejora el pronóstico en los pacientes oncológicos.Pacientes y método:Estudio retrospectivo de casos de pacientes sometidos a cirugía mayor en el periodo de noviembre de 2018 a febrero de 2020. Objetivo principal: cuantificar tipo y dosis de opioide administrado en periodo intraoperatorio y en el postoperatorio inmediato. Objetivos secundarios: graduación del dolor en el postoperatorio y al alta a planta de hospitalización y presencia de náuseas/vómitos en el postoperatorio. Resultados: 157 pacientes fueron incluidos. El 29,9 % de los pacientes no precisaron ninguna dosis de opioide intraoperatorio. De los que sí la precisaron, un 72,7 % de los mismos solo necesitó morfina y a una dosis media de 3,3 mg (± 0,9); un 8,1 % solo recibieron fentanilo (dosis media de 110,1 mcg, ± 57,1), y un 19,2 % recibieron morfina y fentanilo (3,8 mg ± 1,2 y 90,4 mcg ± 62,4, respectivamente). En cuanto a la necesidad de opioide postoperatorio, solo el 31,7 % de los pacientes precisó su administración; de ellos ⅔ (33 pacientes) solo recibieron morfina (4,8 mg ± 2,6), 1/5 (10 pacientes) solo fentanilo (83,3 mcg ± 28,8) y el resto una combinación de fentanilo y morfina (140,6 mcg ± 119,4 y 8 mg ± 5,9, respectivamente).Respecto a la intensidad de dolor, el valor en la escala EVA a la llegada de los pacientes a la Reanimación tuvo un valor de 1,6 ± 1,9 y al alta de 0,3 ± 0,6. Solo dos pacientes tuvieron náuseas o vómitos.Conclusiones:El uso de una técnica OFA es factible en cirugía mayor y permite un adecuado control del dolor. La necesidad de opioides intravenosos, tanto en el intraoperatorio como en el postoperatorio, es menor cuando se realiza una técnica OFA.(AU)

Introduction: Opioid free anaesthesia is a new paradigm that focuses in multimodal analgesia with an opioid sparing approach that provides a good pain management, without nauseas nor vomiting and improves prognosis in oncological patients. Patients and method: Cases retrospective study of major surgery patients from november 2018 to february 2020. Main objective: type and dosage of opioid requeriments both in the intraoperatory and postoperative setting. Secondary objectives: pain level score cuantification at the end of the surgery and at leaving the postoperative recovery unit and incidence of nausea/vomiting. Results:157 patients were recruited. 29,9 % need no opioid intraoperatively. Those who requiered it, 72,7 % only needed morphine (3,3 mg ± 0,9), 8,1 % had to recieved fentanyl (110,1 mcg, ± 57,1) and 19,2 % need both morphine and fentanyl (3,8 mg ± 1,2 and 90,4 mcg ± 62,4). At the postoperative recovery unit, only 31,7 % precised opioids: ⅔ (33 patients) recieved morphine (4,8 mg ± 2,6), 1/5 (10 patients) only fentanyl (83,3 mcg ± 28,8) and the rest needed a combination of fentanyl and morphine (140,6 mcg ± 119,4 and 8 mg ± 5,9, respectively). Two of them have nausea or vomyting.Conclusions:An opioid free anaesthesia approach is feasible in major surgery patients and it achieves and adequate pain management. Opioid requeriments in such patients is less than in those who recieved a traditional base opioid analgesia protocol.(AU)

Association between rs61764370, rs9266, and rs140080026 polymorphisms of the KRAS gene and breast cancer risk in a Mexican population.

OBJECTIVE: Polymorphisms of the KRAS gene have been shown to be associated with cancer. However, their association with breast cancer (BC) has been inconsistent. The purpose of this study was to determine the frequency with which the rs61764370, rs9266, and rs140080026 polymorphisms of the KRAS gene are associated with BC in patients of the Mexican population. PATIENTS AND METHODS: The rs61764370 A>C or T>G and rs140080026 A>G polymorphisms were determined by Polymerase Chain Reaction (PCR), and the rs9266 A>G polymorphism was determined by DNA sequencing of healthy Mexican subjects and BC patients. RESULTS: We observed that 78% of BC patients are overweight and/or obese, 57% have metastatic lymph nodes, 64% have luminal A/B cancer subtypes, and 61% have stage III-IV cancer. The rs61764370 polymorphism was associated with BC susceptibility when the BC patients and the control group were compared for the AC genotype (p = 0.020), AC vs. AA genotypes (heterozygous model: p = 0.016), AC/CC genotype (dominant model: p = 0.002), and the C allele (p = 0.007). The AC/CC genotype (p = 0.018; rs61764370) and AG/GG genotype (p = 0.005; rs9266) were associated with age in BC patients ≥50 years old. The AC/CC (rs61764370) and AG/GG (rs9266) genotypes were classified by molecular subtype, TNM stage, miscarriage, lymph node metastasis, ductal type, and Ki-67. These classifications were also associated with BC patients, indicating that these factors may significantly contribute to BC risk. The AAA (OR 0.65, 95% CI 0.43-0.98, p = 0.039) and CAA (OR 3.25, 95% CI 1.13-9.36, p = 0.021) haplotypes were also associated with BC susceptibility. In addition, 94 polymorphisms were identified on the 3'UTR of the KRAS gene GRCh 38/hg3 (25,209,490-25,209,122) in BC (n = 112) and control (n = 113) samples. However, 92 of these polymorphisms have only expressed the major allele (wild-type allele). CONCLUSIONS: The rs61764370 polymorphism in the KRAS gene was associated with BC susceptibility in the Mexican population. The dominant model of the rs61764370 and rs9266 polymorphisms (classified by molecular subtype, miscarriage, TNM stage, lymph node metastasis, and Ki-67) could significantly contribute to BC risk in patients ≥50 years. The CAA haplotype could significantly contribute to BC risk in the Mexican population analyzed.

Tríada találgica. Una nueva entidad clínica a partir de una serie de casos / Thalalgic triad. A new clinical entity from a case series

Introducción: El dolor crónico en el talón es un cuadro frecuente en la patología del pie. Este tipo de cuadros no están causados por una sola lesión, sino que es el resultado de la combinación de una serie de cuadros clínicos, especialmente por una neuropatía de Baxter y una fascitis plantar. Desde hace varios años, y tras analizar una serie de casos clínicos, se observa que los pacientes con dolor crónico en el talón cursan con un proceso de fasciosis plantar, edema óseo de calcáneo o síndrome congestivo de calcáneo y neuropatía del nervio de Baxter. A raíz de este hallazgo concluimos en una nueva entidad clínica denominada tríada találgica, la cual no presenta referencias bibliográficas anteriores en la literatura científica. Pacientes y métodos: Se ha llevado a cabo una serie de casos de 10 pacientes a los que se les diagnostica una combinación de 3 patologías, denominada tríada találgica, que cursa con aparición de fasciosis plantar, edema óseo de calcáneo (congestión calcánea) y neuropatía compresiva de Baxter. Cada una de estas patologías se trata de forma independiente con distintas terapias, tales como soportes plantares, infiltraciones, tratamiento farmacológico o cirugía. Resultados: Un total de 10 mujeres con una edad media de 53 años fueron diagnosticadas de fasciosis plantar, edema óseo de calcáneo y neuropatía compresiva de Baxter mediante diferentes pruebas, como la ecografía. Estas pacientes fueron tratadas mediante infiltraciones de colágeno, extracción del líquido sanguinolento del calcáneo, terapia electrolisis percutánea intratisular, soportes plantares, tratamiento farmacológico y ondas de choque. El 40 % de la muestra se encontraba de baja laboral debido al dolor incapacitante de esta tríada y el 10 % en situación de jubilación. Conclusiones: La tríada találgica es una entidad clínica desconocida, con un diagnóstico complejo que combina pruebas complementarias con diagnóstico clínico...(AU)

Introduction: Chronic heel pain is a frequent condition in foot pathology. These types of pictures are not caused by a single injury, but are the result of a combination of a series of clinical pictures, especially Baxter's neuropathy and plantar fasciitis. For several years and after analyzing a series of clinical cases, it has been observed that patients with chronic pain in the heel present with a process of plantar fasciosis, calcaneal bone edema or congestive calcaneal syndrome and Baxter nerve neuropathy. As a result of this finding, we conclude on a new clinical entity called thatalgic triad, which does not present previous bibliographic references in the scientific literature. Patients and methods: A series of cases of 10 patients who were diagnosed with a combination of 3 pathologies, called the thatalgic triad, has been carried out, with the appearance of plantar fasciosis, calcaneal bone edema (calcaneal congestion) and neuropathy Baxter compression. Each of these pathologies is treated independently with different therapies, such as plantar supports, infiltrations, drug treatment or surgery. Results: A total of 10 women with a mean age of 53 years were diagnosed with plantar fasciosis, calcaneal bone edema and Baxter's compressive neuropathy by different tests, such as ultrasound. These patients were treated by collagen infiltrations, removal of bloody fluid from the calcaneus, intratissular percutaneous electrolysis therapy, plantar supports, pharmacological treatment, and shock waves. 40 % of the sample was on sick leave due to the disabling pain of this triad and 10 % were in retirement. Conclusions: The thatalgic triad is an unknown clinical entity with a complex diagnosis that combines complementary tests with clinical diagnosis. Likewise, there are very few bibliographic references on this subject.(AU)

PLEX: the best first-line treatment in nmosd attacks experience at a single center in Colombia.

OBJECTIVE: Primary outcome was to evaluate complete improvement at six months after acute treatment in NMOSD relapses. METHODS: Retrospective observational cohort study of patients with diagnosis of NMOSD admitted for acute attacks. We performed an explanatory analysis using the univariate, bivariate and multivariate logistic regression approach. We compared survival curves using the Kaplan Meier analysis and estimated the median time for the main outcome. RESULTS: In the univariate analysis, basal EDSS score, AQP4-IgG positivity, PLEX as a first-line treatment (IVMP + PLEX), less systemic complications related to acute treatment and total attack history were independently associated with complete improvement at six months. After adjusting for confounding variables and using multivariate analysis by Cox Regression, positive AQ4-IgG (HR 0.04, 95% CI: 0.02-0.66) and IVMP + PLEX (HR 5.1, 95% CI: 3.9-66.4), were kept as independent factors associated to time to complete improvement. Time from admission to PLEX initiation and complete improvement at six months had a median of seven days (95% CI: 5.2-8.8). In secondary effects, there were no statistical differences between the groups. CONCLUSIONS: PLEX + IVMP is the treatment of choice for NMOSD relapses and should be initiated as early as possible.

Capsaicin attenuates immunosuppression induced by chronic stress in BALB/C mice.

Although acute stress generally exerts positive effects on the immune system, chronic stress typically causes immunosuppression via the hypothalamic-pituitary-adrenal (HPA) axis. In this study, the effects of capsaicin (1.28 mg/kg intraperitoneally [i.p.] for 7 days) on immune parameters were evaluated under conditions of chronic stress. Capsaicin treatment significantly increased the immune response as evaluated by the delayed-type hypersensitivity (DTH) reaction to dinitrofluorobenzene (DNFB) and splenocyte proliferation assays- It also is able to rescue the splenocytes of the apoptosis induced by stress. The capsaicin treatment increased the production of Th1 cytokines and decreased the production of Th2 cytokines and TGF-ß1 in the plasma and culture supernatants of immunosuppressed mice, which is associated with the modulation of Th2 induced by stress cells. Moreover, the production of corticosterone significantly decreased in capsaicin-treated animals as compared to control groups. The capsaicin treatment further attenuated the immunosuppression induced by the corticosterone treatment (40 mg/kg i.p. for 7 days), albeit less potently, as exhibited in the DTH response. Intriguingly, the capsaicin treatment decreased the induction of IL-10, IL-4, and TGF-ß1 through high doses of corticosterone, indicating direct cellular immunomodulation. These results show, that capsaicin is able to modulate chronic stress-induced immunosuppression, mediating corticosterone released inhibition, but also, that capsaicin significantly modulates the pharmacological action of corticosterone in vivo.

The rs1008562, rs2234671, and rs3138060 polymorphisms of the CXCR1 gene are associated with breast cancer risk in a Mexican population.

OBJECTIVE: The rs1008562, rs2234671 and rs3138060 polymorphisms of the CXCR1 gene have been shown to be associated with many diseases, but in breast cancer (BC) their association has not been detected. The purpose of this study was to determine the frequency and association of the rs1008562, rs2234671 and rs3138060 polymorphisms of CXCR1 gene in BC patients in the Mexican population. PATIENTS AND METHODS: The CXCR1 polymorphisms were determined by Polymerase Chain Reaction (PCR) and real time-PCR in healthy Mexican subjects and BC patients. RESULTS: The prevalent patron in BC patients was observed, the majority were overweight and obesity (72%) with metastatic lymph nodes (48%), luminal A/B subtypes (63%), and advanced stages (60%). Triple negative breast cancer (TNBC) patients: they were younger (58%) than 43 years old, overweight (33%), obesity (42%), ductal type histological (98%), metastasis to lymph nodes (47%), advanced stages III-IV (61%) and metastasis (33%). The rs2234671 polymorphism was associated with BC susceptibility when BC patients and the control group were compared for the CC genotype (p=0.037), CG (heterozygous model: p=0.018), GC/CC (dominant model: p=0.004), and the C allele (p=0.001), as well as the GC/CC genotype with hormone replace therapy (HRT, p=0.016). The rs3138060 polymorphism was associated with BC susceptibility for CG/GG genotype (dominant model: p=0.032) and G allele (p=0.018). Although the association between the dominant model of rs1008562, rs2234671, rs3138060 polymorphisms and BC patients and control was evident for tobacco and alcohol consumption (p<0.05). The rs1008562, rs2234671, and rs3138060 polymorphisms of the CXCR1 gene classified by molecular subtype and stage were also associated with BC patients, indicating that these factors may significantly contribute to BC risk. The CCC (OR 1.75, 95% CI 1.03- 2.97, p=0.046), GGG (OR 3.73, 95% CI 1.61- 8.65, p=0.0018) haplotypes were also associated with BC susceptibility. CONCLUSIONS: Rs2234671 and rs3138060 polymorphisms in the CXCR1 gene were associated with BC susceptibility in the Mexican population. The dominant model of the rs1008562, rs2234671 and rs3138060 polymorphisms could significantly contribute to BC risk in tobacco and alcohol consumption, molecular subtype and stage. The rs1008562, rs2234671 and rs3138060 polymorphisms, and the haplotypes CCC and GGG could significantly contribute to BC risk in the Mexican population analyzed.

The rs2234694 and 50 bp Insertion/Deletion polymorphisms of the SOD1 gene are associated with breast cancer risk in a Mexican population.

OBJECTIVE: The rs2234694 and 50 bp insertion/deletion (Ins/Del) polymorphisms of the SOD1 gene have been shown to be associated with many diseases, but in breast cancer (BC) their association has not been detected. The purpose of this study was to determine the frequency and association of SOD1 gene polymorphisms (rs2234694 and 50 bp Ins/Del) in BC patients in the Mexican population. MATERIALS AND METHODS: The SOD1 polymorphisms were determined by Polymerase Chain Reaction (PCR) in Mexican healthy subjects and BC patients. RESULTS: The rs2234694 polymorphism was associated with BC susceptibility when BC patients and the control group were compared for the AC genotype (p<0.0001), the AC/CC genotype (dominant model: p<0.0001), and the C allele (p<0.0001). The 50 bp Ins/Del polymorphism was associated with BC susceptibility for the Del allele (p=0.048), although the association between the dominant model AC/CC (rs2234694) and BC patients was evident for menopause [adjusted odds ratio (OR) 1.65 (95% CI 1.05-2.7); p=0.048], Ki-67 (≥15%) (OR1.9, 95% CI 1.14- 3.16, p=0.016), and the presence of DM2 (OR 2.4, 95% CI 1.35- 4.31, p=0.003). A protective association for BC of the rs2234694 polymorphism was observed in patients younger than 50 years positive for estrogen receptor (ER) and progesterone receptor (PR), carrying the AC genotypes (OR 0.47, 95% CI 0.23-0.94, p= 0.033) and CC (OR 0.11, 95% CI 0.013-1.07, p=0.047). The association between the InsDel/DelDel (dominant model; 50 bp Ins/Del) genotype and BC with metastatic lymph nodes (OR 1.5, 95% CI 1.1-2.25, p=0.019), hematologic toxicity (OR 1.5, 95%CI 1.1-2.23, p=0.015), gastric toxicity (OR 1.5, 95%CI 1.1-2.07, p=0.030), and Ki-67 (≥15%) (OR1.6, 95%CI 1.2-2.26, p=0.002) was evident, indicating that these factors may contribute significantly to BC risk. The C/Ins haplotype was also associated with BC susceptibility (OR3.47, 95% CI 1.62-7.74, p=0.001). CONCLUSIONS: rs2234694 and 50 bp Ins/Del polymorphisms in the SOD1 gene were associated with BC susceptibility in a Mexican population. A protective association for BC of the rs2234694 polymorphism was observed in patients younger than 50 years positive for ER and PR, carrying the AC genotypes. The haplogenotypes AA/InsIns and AC/InsDel could contribute significantly to BC risk in gastric and hematologic toxicities, metastatic lymph nodes, and the presence of DM2 in the Mexican population analyzed.
