Efectos del ciclismo en la composición corporal e indicadores de riesgo metabólico / Effects of cycling on Body Composition and Metabolic Risk Indicators

Introducción: El ciclismo es una actividad física que se practica de forma recreativa y como actividad laboral, en base a esto los beneficios en la salud varían. Sus efectos pueden extenderse en la regulación de la expresión de citocinas proinflamatorias en la obesidad; sin embargo, se deben estudiar detalles en los indicadores clínicos asociados a otras enfermedades crónico-degenerativas. Objetivo: Identificar los cambios en los parámetros clínicos que sirven como indicadores de riesgo metabólico en personas que realizan ciclismo como ejercicio habitual y como actividad laboral. Métodos: Se realizó una investigación de diseño transversal, descriptivo en el Estado de México, México. Se formaron 3 grupos de 16 participantes provenientes de Toluca y municipios aledaños. Se realizaron mediciones de composición corporal y análisis bioquímicos para identificar las diferencias entre los grupos a través de la prueba t- student y el análisis de varianza ANOVA. Resultados: Los análisis estadísticos reportaron diferencias significativas en las concentraciones de lipoproteínas de alta densindad y triglicéridos. Para el grupo de los conductores de bicitaxi fue más favorable, se detalla como el tiempo de la actividad ayuda a mantener los parámetros de composición corporal como el porcentaje del tejido muscular y adiposo. Conclusiones: Los beneficios del ciclismo se presentaron con diferentes grados de eficiencia de acuerdo con la modalidad en la que se practican. Las variables no cambian de forma significativa en ningún grupo, pueden ser dependientes de otras variables como la alimentación(AU)

Introduction: Cycling is a physical activity, which is practiced recreationally and as a work activity. Its effects may extend to the regulation of the expression of proinflammatory cytokines in obesity; however, details should be studied in the clinical indicators associated with other chronic-degenerative diseases. Objective: To identify changes in clinical parameters that serve as indicators of metabolic risk in people who perform cycling as a regular exercise and as a work activity. Methods: A cross-sectional and descriptive design research was carried out in the State of Mexico, Mexico. Three groups of 16 participants were formed from Toluca and surrounding municipalities. Body composition measurements and biochemical analyzes were performed to identify differences between groups through Student's t test and ANOVA analysis of variance. Results: Statistical analyzes reported significant differences in HDL and triglyceride concentrations. For the group of pedicab drivers it was more favorable, it is detailed how the time of the activity helps to maintain body composition parameters such as the percentage of muscle and adipose tissue. Conclusions: The benefits of cycling were presented with different degrees of efficiency according to the modality in which they are practiced. The variables do not change significantly in any group and may be dependent on other variables such as diet(AU)

Abstract: The identification of multiple risk factors that predispose to bleeding during the obstetric event, such as acquired hemophilia, which is a disorder that develops due to the generation of autoantibodies that inhibit coagulation factors, the objective interpretation of routine laboratory tests , the development of systematized thinking in diagnostic-therapeutic integration by health personnel, and the provision of hospital pharmacological resources, is what frequently determines the prognosis in obstetric patients with extreme morbidity who require multidisciplinary care in the different hospital units of the health sector of our country. The objective is to present a clinical case of extreme morbidity due to acquired hemophilia, its clinical presentation, evolution and fatal outcome. A case referred from another unit of the ISEM (Instituto de Salud del Estado de México) Health Sector, treated at the Obstetric Intensive Care Unit of the «Mónica Pretelini Sáenz¼ Hospital, is presented, highlighting the importance of diagnostic-therapeutic integration, and the multifactorial interaction of variables related to its fatal outcome. Conclusions: Ignorance of the pathology, delay in diagnosis, multiple conditioning procedures of iatrogenic hemorrhage and the limitation in therapeutic resources are factors that contribute to a fatal outcome.

Valor pronóstico de los marcadores bioquímicos en pacientes con COVID-19 / Prognostic value of biochemical markers in patients with COVID-19

Resumen El SARS-CoV-2 es un virus de la familia Coronaviridae, subfamilia coronavirus (CoV) y género β. Este se ha convertido en una amenaza inminente para toda la humanidad por ser el agente causal de la pandemia COVID-19, la cual llevó, por un lado, a la declaratoria de emergencia sanitaria a nivel mundial por parte de la Organización Mundial de la Salud (OMS) y, por otro, a instituir estrictas medidas de control para prevenir su contagio por parte de muchos gobiernos. En cuanto a la fisiopatología presentada en esta entidad, aunque las lesiones pulmonares han sido consideradas como las principales consecuencias de esta infección, a medida que avanza el conocimiento sobre el virus se han identificado también lesiones a nivel cardiaco, hepático y renal, que potencian la severidad de la infección y generan un mayor deterioro de los pacientes, su ingreso a las Unidades de Cuidados Intensivos y un mayor riesgo de mortalidad. Con base en esto, diversas investigaciones se han encaminado a determinar aquellos hallazgos clínicos y paraclínicos que puedan ser relevantes frente al pronóstico de los pacientes. Por lo anterior, la presente revisión aborda literatura disponible sobre los principales biomarcadores bioquímicos reportados por su asociación a daños cardiaco, hepático y renal, los cuales presentan mayor significancia para evaluar el curso, severidad, manejo y pronóstico de la infección, y cuya alteración conlleva finalmente a un mayor riesgo de mortalidad en pacientes hospitalizados que presentan COVID-19.

Abstract SARS-CoV-2 is a virus from the coronaviridae family, coronavirus (CoV) subfamily and genus β, it has become an imminent threat to all humanity as it is the causal agent of the COVID-19 pandemic, which led to On the one hand, the World Health Organization (WHO) declares a worldwide health emergency, and on the other, to institute strict control measures to prevent its spread by many governments. Regarding the pathophysiology presented in this entity, although lung lesions have been considered the main consequences of this infection, as knowledge about the virus progresses, cardiac, hepatic, and renal lesions have also been identified that enhance severity of the infection generating greater deterioration of the patients, their admission to the Intensive Care Units and a higher risk of mortality; Based on this, various investigations have aimed to determine those clinical and paraclinical findings that may be relevant to the prognosis of the patients. Therefore, this review addresses available literature on the main biochemical biomarkers reported for their association with cardiac, liver and kidney damage, which are more significant in evaluating the course, severity, management and prognosis of the infection and whose alteration ultimately leads to an increased risk of mortality in hospitalized patients presenting with COVID-19.

Genotyping of Human Papillomavirus in Cervical Squamous Intraepithelial Lesions in Mexican Women.

Approximately 40 genotypes of the human papillomavirus (HPV) have been identified in cervical mucosa. In particular, HPV-16 and HPV-18 have been associated with cervical neoplasia. Squamous intraepithelial lesions (SILs) are precursors of cervical cancer. This study aimed to identify the HPV by genotype in SILs using a linear array genotyping test in a population in Mexico. We performed a cross-sectional study of 129 female patients with or without SILs, as determined by colposcopy, who completed a risk factor questionnaire. Cervical swab samples were obtained and genotyped using a Linear Array HPV Genotyping assay. Forty-nine (37.98%) samples were positive for HPV, and 24 genotypes were identified among these samples. The most common genotype was HPV-16. Twelve genotypes were found in both high- and low-grade SILs (HPV-6, 16, 31, 39, 51, 52, 53, 58, 59, 61, 67, and 84), of which seven were high-risk SILs (HPV-16, 31, 39, 51, 52, 58, and 59). Among the populations studied, the most frequent genotype was HPV-16, multiple infections were found, and four patients without injury tested positive for HPV.

VIH, dislipidemias y perspectivas de su evolución / HIV, dyslipidemias and perspectives of its evolution

Resumen Con el advenimiento de la terapia antirretroviral (ART), la infección por el virus de inmunodeficiencia humana (VIH) se ha convertido en una enfermedad crónica con complicaciones metabólicas importantes más acentuadas que en la población general. Mientras no se tenga una vacuna que erradique las tasas de infección y no exista una cura para esta pandemia, se debe ser más incisivo en el controlar las comorbilidades, entre las que destacan las alteraciones en el perfil de lípidos pues aumentan el riesgo cardiovascular.

Abstract With the advent of antiretroviral therapy (ART), infection with the human immunodeficiency virus (HIV) has become a chronic disease with major metabolic complications more pronounced than in the general population. While there is no vaccine to eradicate infection rates and there is no cure for this pandemic, it should be more incisive in controlling comorbidities, among which alterations in the lipid profile stand out as they increase cardiovascular risk.

sRANKL and its correlation with metabolic syndrome parameters in children.

BACKGROUND: Activating receptor ligand for nuclear factor (RANKL) has been identified as a ligand attached to the cell membrane of osteoblasts and odontoclasts. AIM: To determine a possible association of sRANKL in saliva and serum with the parameters of metabolic syndrome (MS) in paediatric population aged 8-12 years. DESIGN: This was a clinical, analytical and comparative study. Students between 6 and 12 years with good oral hygiene were included. Anthropometry, clinical analysis, dentobacterial plaque registration were registered as well as sRANKL in total saliva and serum through the ELISA technique. RESULTS: A total of 43 children were enrolled, with a mean age of 9.7 (±0.8 years). Contrasting the groups by the presence or absence of the waist circumference above the normal limit, the difference in serum sRANKL concentration was statistically significant (P ≤ 0.05). A negative statistical significance was found in the correlation between serum sRANKL and HDLc (r2  = -0.310, P = 0.046). Saliva sRANKL did not show statistical difference between neither gender nor body mass index and was not correlated with any parameter of the MS. CONCLUSIONS: A good oral hygiene seems to avoid the effects of MS on the oral cavity.

FOXE1 Mutation Screening in a Case with Cleft Lip, Hypothyroidism, and Thyroid Carcinoma: A New Syndrome?

A 26-year-old woman is referred to the Internal Medicine consultation due to increases in laboratory studies associated with Papillary Thyroid Carcinoma (PTC) that was confirmed by histopathological studies. Her clinical history revealed that, at 3 months of age, she was successfully treated with surgery for cleft lip (CL) and at the age of 24 years was diagnosed with hypothyroidism. Single nucleotide polymorphisms (SNPs) in FOXE1 and its promoter regions have been associated with various etiologies related to the thyroid, including orofacial clefting, specially cleft palate (CP) and CL, hypothyroidism (HT), and thyroid cancer. The association of CL, HT, and PTC might be component of a new syndrome; however FOXE1 coding region, which has been involved with these entities, has not exhibited mutations or SNPs. Further study of other genes may help in better characterization of the possible syndrome.

Intracellular Signaling Pathways Involved in Childhood Acute Lymphoblastic Leukemia; Molecular Targets.

Acute lymphoblastic leukemia (ALL) is a malignant disease characterized by an uncontrolled proliferation of immature lymphoid cells. ALL is the most common hematologic malignancy in early childhood, and it reaches peak incidence between the ages of 2 and 3 years. The prognosis of ALL is associated with aberrant gene expression, in addition to the presence of numerical or structural chromosomal alterations, age, race, and immunophenotype. The Relapse rate with regard to pharmacological treatment rises in childhood; thus, the expression of biomarkers associated with the activation of cell signaling pathways is crucial to establish the disease prognosis. Intracellular pathways involved in ALL are diverse, including Janus kinase/Signal transducers and transcription activators (JAK-STAT), Phosphoinositide-3-kinase-protein kinase B (PI3K-AKT), Ras mitogen-activated protein kinase (Ras-MAPK), Glycogen synthase kinase-3ß (GSK-3ß), Nuclear factor-kappa beta (NF-κB), and Hypoxia-inducible transcription factor 1α (HIF-1α), among others. In this review, we present several therapeutic targets, intracellular pathways, and molecular markers that are being studied extensively at present.

Asociación de factores de riesgo de preeclampsia en mujeres mexiquenses / Association preeclampsia risk factors in mexiquenses women

Introducción: La preeclampsia es aún uno de los mayores problemas obstétricos en países en vías de desarrollo.Objetivo: Identificar los principales factores de riesgo para desarrollar preeclampsia en mujeres mexiquenses atendidas en el Hospital Materno Perinatal "Mónica Pretelini Sáenz".Material y métodos: Estudio de casos y controles, se incluyeron dos grupos, el grupo A casos (n=138) y el grupo B controles (n=276) con relación caso-control de 1:2.Los criterios de definición para los casos fueron: mujeres con diagnóstico inicial de preeclampsia y que cuenten con las siguientes mediciones: Tensión Arterial Sistólica (TAS)=140 ó Tensión Arterial Diastólica (TAD)=90 mmHg más una de las siguientes: concentración de proteínas en orina de 24 h =300 ó Proteinuria =++. El grupo de controles quedó conformado por mujeres que acudieron al hospital para atención del embarazo sin preeclampsia. Resultados: La media de edad fue de 27.5±8.0 para los casos (grupo A) y 25.3±6.7 para los controles (grupo B) (P<0.01). El tener 1 o más óbitos (P<0.045), las cifras iniciales y finales de TAS y TAD, el índice de masa corporal pregestacional (IMCPG), el peso al final del embarazo, y la hipertensión arterial sistémica crónica (P<0.01) así como el haber padecido preeclampsia en algún embarazo previo fueron estadísticamente significativo (P<0.01) para tener preeclampsia. Conclusiones: En nuestra población, además de los factores de riesgo tradicionales para preeclampsia se agrega el antecedente de óbitos como otro factor de riesgo para padecer preeclampsia.

Introduction: Preeclampsia is still a major obstetric problem in developing countries. Objective: To identify the main risk factors to develop preeclampsia in women from the State of Mexico attended at the Maternal Perinatal Hospital "MónicaPreteliniSáenz". Materials and methods: In this case-control study, two groups were included, group A patients (n = 138) and B controls (n = 276) with a case-control ratio of 1: 2. The criteria for defining cases were women initially diagnosed with preeclampsia and who had the following measurements: Systolic Blood Pressure (SBP) =140 or diastolic blood pressure (DBP) =90 mmHg plus one of the following: =300 protein concentration in a 24-h urine sample or proteinuria = ++. The control group was made up of women attended at the hospital who did not develop preeclampsia. Results: The mean age was 27.5 ± 8.0 years for the cases (group A) and 25.3 ± 6.7 years for controls (group B) (P <0.01). Having 1 or more stillbirth (P <0.045), initial and final measures of SBP and DBP, the pre-pregnancy body mass index (IMCPG), weight in late pregnancy, and chronic hypertension (P <0.01) as well as having had preeclampsia in a previous pregnancy were statistically significant (P <0.01) to have preeclampsia. Conclusions: In our population, in addition to the traditional risk factors for preeclampsia, history of stillbirthswas is another risk factor to develop preeclampsia.

Evaluación de factores de riesgo asociados a enfermedad cardiovascular en jóvenes universitarios de la Localidad Santafé en Bogotá, Colombia / Evaluation of risk factors associated with cardiovascular disease in young university students of Santafe Locality from Bogota, Colombia

Objetivo. Identificar factores de riesgo cardiovascular en población joven de la Localidad Santafé de Bogotá, Colombia. Métodos. Estudio descriptivo, transversal desarrollado en estudiantes de tres universidades de la Localidad Santafé en Bogotá, con edades comprendidas entre los 16 a 29 años, a quienes se les realizaron exámenes clínicos y paraclínicos y se les aplicó una encuesta de factores de riesgo. Resultados. Se estudiaron 747 estudiantes, encontrando que la prevalencia más alta de factores de riesgo estuvo dada por el consumo de alcohol (96.1%), que mostró además relación con el aumento de tensión arterial con la prueba Chi cuadrada. Las prevalencias de sedentarismo (63.8%) y tabaquismo (48.1%) no presentaron diferencias marcadas en comparación con otros estudios, pero el segundo fue el único que se asoció con el aumento de la tensión arterial sistólica (P < 0.001) y diastólica (P = 0.04). La prevalencia de obesidad fue similar a la hallada en investigaciones anteriores hechas en Colombia (2.3%); de igual manera se encontró asociación entre aquella, la presencia de hipertrigliceridemia (P = 0.001) y el incremento en los niveles de glucosa (P = 0.01). Los resultados de este estudio indican que los estudiantes universitarios de la Localidad Santafé en Bogotá, tienen como factores de riesgo preponderantes de enfermedad cardiovascular al consumo de alcohol, el tabaquismo y el sedentarismo.

Objective. To identify cardiovascular risk factors in young people of Santafé Locality of Bogotá, Colombia. Method. This was a descriptive cross-sectional study conducted at three universities in the Santafe Locality of Bogota, aged 16-29 years, who underwent clinical and laboratory examinations and they were asked to answer a risk factor questionnaire. Results. 747 students were evaluated, finding that the highest prevalence of cardiovascular risk factor was alcohol (96.1%), also related to an increased blood pressure with the Chi square test. The prevalence of physical inactivity (63.8%) and smoking (48.1%) showed no marked differences compared with other studies, and the second was the only one that was associated with increased systolic (P < 0.001) and diastolic blood pressure (P = 0.04). The prevalence of obesity was similar to that found in previous research (2.3 %); and it was also associated to the presence of high levels of triglycerides (P = 0.001) and increase in blood glucose (P = 0.01). The results of this study indicate that college students in the Santafe Locality of Bogotá, have as main risk factors of cardiovascular disease, alcohol consumption, smoking and physical inactivity.

Trends of inflammatory markers and cytokines after one month of phototherapy in patients with rheumatoid arthritis.

OBJECTIVE: to evaluate changes in the expression of tumor necrosis factor-α in patients with rheumatoid arthritis submitted to phototherapy. MATERIALS AND METHODS: This was an open label study, enrolling ten patients. The phototherapy scheme within a range of 425 to 650 nm, 11.33 Joules/cm2, 30 cm above the chest was as follows: a) 45-min daily sessions from Monday to Friday for 2 to 3 months; b) three, 45- min weekly sessions for 1 to 2 months; c) twice weekly 45-min sessions for 1 to 2 months, and d) one weekly session for 1 to 2 months until completion. Erythrocyte sedimentation rate, C-reactive protein and rheumatoid factor were measured in peripheral blood and tumor necrosis factor-α, interleukin-1ß, and interleukin-10 in leukocytes by quantitative real-time Reverse transcriptase-Polymerase chain reaction. In all the patients the next indexes: Karnofsky scale, Rheumatoid Arthritis-specific quality of life instrument, Steinbrocker Functional Capacity Rating and the Visual Analog Scale were evaluated. RESULTS: Erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor declined notoriously after the indicated sessions. In gene expression, there was a tendency in tumor necrosis factor-α to decrease after 1 month, from 24.5±11.4 to 18±9.2 relative units, without reaching a significant statistical difference. The four tested indexes showed improvement. CONCLUSION: Phototherapy appears to be a plausible complementary option to reduce the inflammatory component in rheumatoid arthritis.

Familial autoimmune thyroid disease and PTPN-22.

AIM: Autoimmune thyroid disease (AITD) is a multifactorial disease with a genetic predisposition. The protein tyrosine phosphatase-22 (PTPN-22) gene is a powerful inhibitor of T-cell activation. The aim of this study was to compare messenger RNA (mRNA) PTPN22 expression between healthy persons and patients with hypothyroidism and with their affected relatives. METHODS: This was a cross-sectional, prospective and descriptive study. DNA was extracted from leukocytes (4,000-10,000 cells) using the Magna Pure LC 2.0 Instrument and MagNA Pure LC RNA Isolation Kit I (Roche, Germany). A real-time polymerase reaction (qPCR) was performed utilizing the primer sets specific for the PTPN-22 gene, and the succinate dehydrogenase complex, the subunit A, Flavoprotein (Fp) (SDHA) constitutive gene. All reactions were performed with the 7500 Fast Real Time PCR System (Applied Biosystems, Applera International, Inc. Cheshire, UK) employing the SYBR Advantage qPCR Premix Kit (Clontech, USA). RESULTS: Twenty five patients with AITD (hypothyroidism), all females (mean age 39.6 ± 11.8 years) and 23 control subjects (mean age 24.4 ± 4.2 years) were included in the study. There was no statistical difference between both groups in PTPN-22 mRNA expression (p = 0.125). CONCLUSION: There is no clear difference in mRNA PTPN-22 expression. The ideal genes for a systematic screening for familial AITD are yet to be found.

[Expression of gamma interferon during HPV and Chlamydia trachomatis infection in cervical samples]. / Expresión de interferón gamma en la infección por el virus del papiloma humano y por Chlamydia trachomatis en muestras cervicales.

INTRODUCTION: The aim of this study was to mesure the expression of gamma interferon in HPV and Chlamydia trachomatis infection in squamous intraepithelial lesions. METHOD: Samples from 100 patients diagnosed by colposcopy with or without squamous intraepithelial lesions were used in the present study. Each patient was found to be infected by HPV and C.trachomatis. Relative gamma interferon mRNA expression was assessed using a real-time reverse transcriptase PCR assay (RT-PCR). RESULTS: The relative units of expression of gamma interferon mRNA were 13, 1.8 and 0.3, for HPV and C.trachomatis co-infection, or HPV or C.trachomatis infection, respectively. CONCLUSION: HPV and C.trachomatis could overstimulate the expression of gamma interferon.

Comparative study of risk factors related to cardiovascular disease in children from Bogotá, Colombia and Toluca, Mexico.

INTRODUCTION: Currently, cardiovascular risk factors have not been studied so extensively in young people. OBJECTIVE: To compare the cardiovascular risk factor between Colombian and Mexican children. PATIENTS AND METHODS: This was a transversal, descriptive, comparative and clinical study. 30 children of primary school aged 6-12 from Bogotá, Colombia were matched by age with a sample of 30 children from Toluca, Mexico. Cardiovascular risk factors measured were Body Mass Index (BMI), serum lipid profile, glucose and homocystein (Hcy). Besides we applied the validated surveys formats for food (dietary history), physical activity (International Physical Activity Questionnaire, IPAQ), alcohol consumption and smoking. RESULTS: BMI was higher in Mexican children than in Colombian (20.43±3.35 vs 16.92±3.46) (p≤0.001). Among Mexican children, 20% (6) of them had blood glucose concentration greater than 100 mg/dl, 6.6% (2) had triglycerides greater than 200 mg/dl, 36.6% (11) had cholesterol levels greater than 170 mg/dl, 16% (53.3) had HDL lower than the recommended limits, and 60% (18) had LDL above the normal limit. For the Colombian population these percentages were of 0, 3.3, 46.6, 13.33 and 53.3 respectively. DISCUSSION: Mexican children had a stronger correlation between BMI and atherogenic indices and less physical activity than Colombian. Of the 30 Mexican children enrolled in the study only 13% had none of the cardiovascular risk factors, while in the Colombian this percentage was of 33. CONCLUSION: Latin American children are not metabolically homogeneous, Mexican children are at high risk of cardiovascular disease.

Valor pronóstico de la PCT y proteína C reactiva como marcadores de gravedad en neumonía adquirida en la comunidad en adultos mayores / Prognostic value of PCT and CRP as markers of severity in community acquired pneumonia in older adults

Introducción: La neumonía adquirida en la comunidad (NAC) es una de las principales causas de mortalidad en el mundo. La proteína C reactiva puede identificar a pacientes críticamente enfermos. La procalcitonina (PCT) ha sido referida como un marcador sensible de gravedad de la infección bacteriana y sepsis. Metodología: Se realizó un estudio cohorte prospectivo en el servicio de geriatría del Centro Médico ISSEMYM, Metepec, Estado de México, con todos los pacientes que ingresaron a hospitalización con diagnóstico de NAC entre mayo 2012 a marzo 2013. Se midieron PCR, PCT y laboratorios de rutina. Para la comparación de variables continuas se utilizó la T de Student ó U de Mann Whitney según su distribución. Para la comparación de variables cate-góricas se utilizo la prueba de X2. Para el análisis de supervivencia se utilizó el estimador de Kaplan-Meier. Para establecer el riesgo de mortalidad se empleó el modelo de regresión de COX obteniendo el Hazard Ratio. Para la correlación entre los niveles séricos de PCT y PCR se utilizó el coeficiente de correlación de Spearman. Resultados: Se registraron los datos de un total de 82 pacientes. La supervivencia media cuando PCT > de 0.5 ng/dl fue de 17 días (IC 95%, 11 a 23 días) versus 26 días (IC 95%, 17 a 35 días) para PCT < de 0.5 ng/dl (p < 0.01). Conclusiones: El nivel sérico de PCT mayor a 0.5 ng/dl mostró ser un marcador pronóstico en pacientes geriátricos con neumonía...(AU)

Effectiveness of Toki's criteria and determination of variables for identification of HPV L1 protein in oral lesions.

OBJECTIVE: To evaluate the effectiveness of Toki's criteria in identifying the HPV L1 protein in oral lesions with the use of immunohistochemistry (IHC) and to determine which criteria optimize such identification. STUDY DESIGN: Retrospective study of 277 cases diagnosed as HPV lesions at 22 years. Tests of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), kappa coefficients, and chi2 values, as well as two logistic regression analyses (p≤0.05), were conducted. RESULTS: Of the lesions studied, 96.4% (267 of 277) were positive for HPV using Toki's criteria and 28.5% (79 of 277) were positive for L1 by IHC. Toki's criteria showed sensitivity=93.67%, specificity=2.53%, PPV=6.99%, and NPV=46.55%. Neither concordance nor statistically significant associations were observed between both tests. The logistic regression of Toki's criteria was useful in the diagnosis of L1, correctly classified 71.8% of the lesions positive for L1, and showed a Hosmer-Lemeshow adjustment of p=0.614 and a Nagelkerke's coefficient of determination of 6.8%. The explanatory variables statistically significant at p≤0.05 were dyskeratosis (p=0.01) and papillomatosis (p=0.04). Forty-nine independent variables (clinical and histopathologic) were involved in the second regression analysis. The model correctly classified 85.2% of the lesions and showed a Hosmer-Lemeshow adjustment of p=0.696 and a Nagelkerke's coefficient of determination of 60.2%. The explanatory variables statistically significant at p≤0.05 were: age younger than 35 years (p=0.001), multiple lesions (p=0.031), hyperorthokeratosis (p=0.019), focal intracellular edema (p=0.002), and the presence of 1 to more than 5 cells with degenerative changes in their nucleus (p=0.048). CONCLUSIONS: Toki's criteria are not adequate to make a diagnosis of lesions by HPV in the mouth, but the logistic regression analysis showed clinical and histopathologic variables which optimize the identification of lesions through the L1 protein. However, a PCR study is advisable when the presence of high-risk HPV is suspected.

JAK2, STAT3 and SOCS3 gene expression in women with and without breast cancer.

INTRODUCTION: Breast cancer is a disease that arises from the accumulation of alterations in the genome of cells that make up the mammary gland. The Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway has been reported to participate in the development of breast cancer and is activated by adipocytokines such as leptin, which are elevated in obesity. In contrast, alterations in suppressor of cytokine signaling 3 (SOCS3) gene expression have been found in patients with decreased breast cancer metastasis. OBJECTIVE: The current study sought to identify whether JAK2, STAT3 and SOCS3 gene expression is associated with body mass index (BMI) and breast cancer. METHODS: This was a cross-sectional prospective study. JAK2, STAT3 and SOCS3 gene expression levels were determined using RT-qPCR from the biopsies of 26 patients with breast cancer and 43 patients with benign breast lesions. We compared the expression of these genes, relative to the housekeeping genes, ACTB and GAPDH, against BMI, clinical stage and immunohistochemistry. RESULTS: STAT3 gene expression was increased in breast cancer patients (p≤0.001; AUC=0.65; AUC 95% CI: 0.5-0.8), and SOCS3 expression was decreased in obese patients with benign breast lesions (p≤0.001; AUC=0.51; AUC 95% CI: 0.36-0.65). With regard to the clinical stage, there were significant differences in STAT3 gene expression between stage II and III (p≤0.011) and stage II and IV (p≤0.033) breast cancers. Among all women, there was a positive correlation between JAK2 and STAT3 expression (R=0.493, p=0.000). In addition, breast cancers that were negative for HER2 were associated with JAK2 and SOCS3 (R=0.645, p=0.003). CONCLUSION: High levels of STAT3 expression were associated with early stages of breast cancer development and patients in the control group with obesity showed higher expression of SOCS3 regarding overweight.
