RESUMO
Introducción: El estado funcional se mide mediante la autonomía que tienen las personas para desarrollar las actividades de la vida diaria, cuando no se pueden realizar de manera autónoma es necesario un cuidador. Esta medida se sustenta en el modelo de adaptación de Sor Callista Roy, ya que se identifica el proceso de envejecimiento como el estímulo focal que produce una respuesta inmediata en el adulto mayor de acuerdo con el modo de interdependencia. Objetivo: Conocer el nivel de dependencia funcional de los adultos mayores de la comunidad de Tula de Allende, Hidalgo. Material y métodos: Estudio de aplicabilidad básica, cuantitativo, descriptivo y trasversal. Participaron 366 adultos mayores de Tula de Allende, y se les dio a conocer los términos de confidencialidad conforme a lo establecido en la Ley General de Salud y Declaración de Helsinki mediante el consentimiento informado. Se aplicó el cuestionario de Índice de Barthel (IB), para medir la dependencia funcional en las actividades instrumentales de la vida diaria. Resultados: Predomina el género femenino con el 52.7% representado por 193 participantes, la mayoría son casadas y amas de casa. De acuerdo con el IB la mayoría de los participantes tiene una dependencia leve, con una frecuencia de 206 y un porcentaje de 56.3%, y el cruce de variables arroja como resultado una relación significativa. Conclusión: Los adultos mayores de la comunidad de Tula de Allende presentan un nivel de dependencia funcional leve.
Introduction: Functional status assesses people's ability to carry out daily activities; when these cannot be performed autonomously, a caregiver is necessary. This measure is based on the Roy Adaptation Model, which identifies the aging process as the focal stimulus that generates an effect according to the interdependence mode. Objective: To evaluate the level of functional dependence of the elderly in the community of Tula de Allende, Hidalgo. Material and methods: Quantitative, descriptive, and cross-sectional study of basic applicability. 366 older adults from Tula de Allende participated and were informed about confidentiality terms in accordance with the General Health Law and the Declaration of Helsinki through informed consent. The Barthel Index (BI) questionnaire was applied to measure functional dependence on daily instrumental activities. Results: The female gender predominates with 52.7% represented by 193 participants, the majority are married housewives. According to the BI, most of the participants have a slight dependency, with a frequency of 206 and a percentage of 56.3%; the correlation of variables showed statistical significance.

Introducción: la Organización Mundial de la Salud (OMS) declara que el deterioro cognitivo afecta a nivel mundial a unos 50 millones de personas y se calcula que entre un 5 y un 8 % de la población general de 60 años o más sufre deterioro cognitivo en un determinado momento. En la población mexicana se espera un crecimiento exponencial de la población geriátrica y, en consecuencia, un aumento significativo de casos de demencia. Ahora, se cuenta con algunos reportes clínicos sobre la presencia de 500 mil a 700 mil personas con demencia, de las cuales se estima que 25 % no han sido diagnosticadas. Objetivo: evaluar el nivel de deterioro cognitivo del adulto mayor de la comunidad de Tlahuelilpan, Hidalgo. Material y métodos: investigación de aplicabilidad básica con un enfoque cuantitativo y un nivel de alcance descriptivo además un diseño descriptivo transversal Resultados: en nuestra población de estudio predominó el género femenino, el rango de edad se centró entre 60 y 90 años de edad, prevalece el nivel de escolaridad primaria y estado civil casados, el más alto porcentaje de los adultos mayores no tienen deterioro cognitivo. Conclusión: se encontró a nuestra población sin deterioro cognitivo.
Introduction: the World Health Organization (WHO) states that cognitive impairment affects glo¬bally about 50 million people and it is estimated that between 5% and 8% of the general population aged 60 years or older suffers cognitive impairment at any given time. A significant increase in cases of cognitive impairment is expected In the Mexican population, an explosive growth of the geriatric population is expected and, consequently, a significant increase in cases of dementia. Currently there are some clinical reports on the presence of 500,000 to 700,000 people with dementia, of which it is estimated that 25 % have not been diagnosed. Objective: to assess the level of cognitive impairment of older adults in the community of Tlahuelilpan, Hidalgo. Material and methods: research of basic applicability with a quantitative approach and a descriptive scope level in addition to a cross-sectional descriptive design. Results: in our study population there was a predominance of female gender, the age range was between 60 and 90 years of age, with a predominance of primary school level and mostly married, the highest percentage of older adults were found without cognitive impairment.

The aim of this work was to determine the relationship of intracellular reactive oxygen species (ROS) and the disulphide bonds established between sperm proteins with the achievement of capacitation in boar spermatozoa. With this purpose, spermatozoa were incubated in a specifically designed in vitro capacitation medium (CM) in the presence or absence of reduced glutathione (GSH). Incubation of boar spermatozoa in CM for 4 h significantly (p < 0.05) increased free cysteine residues, which is a marker of disrupted disulphide bonds, and also intracellular ROS levels. The addition of GSH to the medium prevented most capacitation-like changes in sperm motility, membrane lipid disorder, mitochondrial membrane potential, intracellular calcium levels and localization of tyrosine-phosphorylated proteins (pTyr), but not in tyrosine phosphorylation of P32. These effects were accompanied by the inhibition of the ability of sperm cells to trigger the acrosome exocytosis in response to progesterone. When GSH was added together with progesterone after 4 h of incubation, acrosome exocytosis was not altered, but the subsequent decrease in intracellular calcium observed in controls cells was inhibited. Furthermore, co-incubation of oocytes with spermatozoa previously incubated in CM in the presence of GSH for 4 h significantly (p < 0.05) increased the number of spermatozoa attached to the oocyte surface but decreased normal fertilization rates. Our results suggest that boar sperm capacitation is related to an increase in disrupted disulphide bonds and intracellular ROS levels and that both events are related to the regulation of hyperactivated motility, intracellular calcium dynamics, sperm binding ability to the oocyte and achievement of proper nuclear decondensation upon oocyte penetration.

BACKGROUND: With the availability of high-quality asthma guidelines worldwide, one possible approach of developing a valid guideline, without re-working the evidence, already analysed by major guidelines, is the ADAPTE approach, as was used for the development of National Guidelines on asthma. METHODS: The guidelines development group (GDG) covered a broad range of experts from medical specialities, primary care physicians and methodologists. The core group of the GDG searched the literature for asthma guidelines 2005 onward, and analysed the 11 best guidelines with AGREE-II to select three mother guidelines. Key clinical questions were formulated covering each step of the asthma management. RESULTS: The selected mother guidelines are British Thoracic Society (BTS), GINA and GEMA 2015. Responses to the questions were formulated according to the evidence in the mother guidelines. Recommendations or suggestions were made for asthma treatment in Mexico by the core group, and adjusted during several rounds of a Delphi process, taking into account: 1. Evidence; 2. Safety; 3. Cost; 4. Patient preference - all these set against the background of the local reality. Here the detailed analysis of the evidence present in BTS/GINA/GEMA sections on prevention and diagnosis in paediatric asthma are presented for three age-groups: children with asthma ≤5 years, 6-11 years and ≥12 years. CONCLUSIONS: For the prevention and diagnosis sections, applying the AGREE-II method is useful to develop a scientifically-sustained document, adjusted to the local reality per country, as is the Mexican Guideline on Asthma.

This study evaluated the potential antimicrobial properties of a polyguanidine (CatDex) on two oral bacteria. Chlorhexidine gluconate 1340 µmoL L-1 (CHX 0.12%) was used as control. Streptococcus mutans (S. mutans) and Porphyromonas gingivalis (P. gingivalis) were grown in BHI media. Bacterial sensitivity and antimicrobial activity were determined by the minimum inhibitory concentration (MIC) and Kirby-Bauer methods. To study side effects, that is, toxicity, dental pulp stem cells (DPSCs) were used. Fluorometric cytotoxicity and confocal microscopy assays were used in order to test cell viability. CatDex inhibited growth of S. mutans at all concentrations and growth of P. gingivalis at all concentrations except 25 µmoL L-1. The MIC of CatDex was 50 µmoL L-1 for both S. mutans and P. gingivalis. The inhibition of bacteria exposed for 8 h at 50 µmoL L-1 of CatDex exhibited increased antimicrobial activity over time, with 91% inhibition in both bacteria. The antimicrobial activities of CatDex and CHX were similar when tested on two common bacteria. CatDex was significantly less toxic to DPSCs. CatDex toxicity depended on time and not on concentration. With regard to clinical relevance, CatDex may have potential as a novel antimicrobial agent. Further studies are in progress.
RESUMO
ABSTRACT The importance of behavioral and physiological biomarkers and their effects on the dairy production of dual purpose cattle was evaluated through the collection and analysis of the primary information. The database maintained by the University of the Amazon, the National University of Colombia, and SCIELO, was analyzed using the keywords: animal welfare, ethology and bovine behavior. It was observed that the activities to which the cows are subjected in dairy production lead to an inevitable stress for the animal due to the conditions of the system, negatively affecting the production, specifically the quantity and quality of milk produced (Total solids, fats and proteins). Greater knowledge regarding animal welfare will contribute to a better understanding of the behavior of dual purpose cattle in dairy production, subject to different management conditions. In this sense, ethology becomes a powerful tool that helps to understand how these animals perceive their environment.
RESUMEN Se evaluó a través de la recopilación y análisis de la información primaria, la importancia de los biomarcadores conductuales, fisiológicos y sus efectos en la producción lechera de bovinos doble propósito. Se analizó la base de datos que mantiene la Universidad de la Amazonia, la Universidad Nacional de Colombia, y SCIELO, usando las palabras clave: bienestar animal, etología y comportamiento bovino. Se observó que las actividades a las que son sometidas las vacas en producción lechera conllevan un estrés inevitable para el animal debido a las condiciones mismas del sistema, afectando negativamente la producción, específicamente la cantidad y calidad de leche producida (Solidos totales, grasas y proteínas). Un mayor conocimiento en lo que se refiere a bienestar animal contribuirá al mejor entendimiento de la conducta del ganado doble propósito en producción lechera, sometido a diferentes condiciones de manejo. En este sentido la etología se convierte en una herramienta poderosa que ayuda a comprender cómo perciben estos animales su entorno.
RESUMO
BACKGROUND: While 18F-fluorodeoxyglucose and 18F-sodium fluoride with positron emission tomography relate with inflammation and calcification, their role in the assessment of patients with Takayasu arteritis has not yet been studied. METHODS: We present 5 patients with suspected active metabolic disease who underwent PET with 18F-fluorodeoxyglucose and 18F-sodium fluoride in order to explore the locations and correlations of 18F-fluorodeoxyglucose and 18F-sodium fluoride uptakes. Diagnosis of metabolic active disease was based on 18F-fluorodeoxyglucose uptake. RESULTS: We studied 3 female patients and 2 male patients. Median age was 29 years (min: 19 max: 63). In areas with atherosclerotic plaques, we found a negative correlation between 18F-sodium fluoride and 18F-fluorodeoxyglucose uptakes (r = -0.78) (P = .001). Meanwhile, in areas with only metabolic active disease, we found a positive correlation between 18F-sodium fluoride and 18F-fluorodeoxyglucose uptakes (r = 0.94) (P = .019). CONCLUSIONS: In Takayasu arteritis, 18F-sodium fluoride uptake can document different stages of metabolic disease, even in the absence of active metabolic disease or symptoms.

INTRODUCTION: Lumbar hernia account for less than 2% of al abdominal hernias, been the Grynfelt-Lesshaft's hernia (GLH) more frequent than the others. With approximately 300 cases published in the literature, the general surgeon may have the chance of treat it ones in their professional life. CASE REPORT: A 42-years old male with human immunodeficiency virus and Diabetes Mellitus presented to the outpatient clinic with a GLH. Preoperative classified as a type "A" lumbar hernia an open approach was scheduled. We performed a Sandwich technique with a sublay and onlay ULTRAPRO(®) mesh fixed with PDS(®) II suture without complications and discharged the patient 24-h after. After six months, the patient denied any complication. DISCUSSION: Primary (spontaneous) lumbar hernias represent 50-60% of all GLH. The preoperative classification of a lumbar hernia is mandatory to propose the best surgical approach. According to the classification of Moreno-Egea A et al., the best technique for our patient was an open approach. The Sandwich technique has demonstrated good outcomes in the management of the GLH. CONCLUSION: The surgical approach should be according to the classification proposed and to the experience of the surgeon. The Sandwich technique has good outcomes.
RESUMO
This work evaluates the radiological risk that patients treated with I for differentiated thyroid cancer could present to relatives and occupationally exposed workers. Recently, the International Atomic Energy Agency issued document K9010241, which recommends that patient discharge from the hospital must be based on the particular status of each patient. This work measures effective dose received by caregivers of patients treated with I at the Instituto Nacional de Cancerología, Mexico City. Thermoluminescent dosimeters were carried during a 15-d period by 40 family caregivers after patient release from hospital. Relatives were classified into two groups, ambulatory and hospitalized, according to the release mode of the patient, and three categories according to the individual patient home and transport facilities. Categories A, B, and C were defined going from most to least adequate concerning public exposure risk. Measurements were performed for 20 family caregivers in each group. The effective dose received by all caregivers participating in this study was found to be less than 5 mSv, the recommended limit per event for caregivers suggested by ICRP 103. In addition, 70 and 90% of ambulatory and hospitalized groups, respectively, received doses lower than 1 mSv. Caregivers belonging to category C, with home situations that are not appropriate for immediate release, received the highest average doses; i.e., 2.2 ± 1.3 and 3.1 ± 1.0 mSv for hospitalized and ambulatory patients, respectively. Results of this work have shown that the proper implementation of radiation protection instructions for relatives and patients can reduce significantly the risk that differentiated thyroid cancer patients treated with I can represent for surrounding individuals. The results also stress the relevance of the patient's particular lifestyle and transport conditions as the prevailing factors related to the dose received by the caregiver. Therefore, the patient's status should be the criterion used to decide his/her release modality. This work provides support to recommend the implementation of the "patient specific release criteria" in accordance with ICRP 94, IAEA Safety Report No. 63, and IAE document K9010241 A for patients treated with radiopharmaceuticals.

OBJECTIVE: To show that patients with intertrochanteric fractures treated with a proximal femoral nail have a better postoperative course than those treated with a DHS plate (dynamic hip screw). METHODS: Patients with a Boyd & Griffin type II intertrochanteric fracture were randomly divided into two groups: a group of patients treated with a PFN and another one treated with a DHS plate. All patients were assessed at 2, 4, 8 and 16 weeks using the Harris scale and the visual analog scale pre- and postoperatively, as well as the operative time, incision size, intraoperative bleeding, onset of partial and/or total weight bearing, healing time, time to attain prior physical activity level, and radiographic result. RESULTS: 32 patients met our criteria. The variables that had a significant reduction were: incision, operative time, postoperative pain according to the visual analog scale, onset of mobility, partial weight bearing and pain at 2 weeks. CONCLUSIONS: The proximal femoral nail has better short-term outcomes than the DHS plate; however, in the medium term both implants have the same outcomes.
