Niveles séricos de PAPP-A y beta-hCG en el primer trimestre del embarazo como predictores de resultados obstétricos desfavorables en el Hospital Universitario Nuestra Señora de Candelaria / Serum levels of PAPP-A and beta-hCG in the first trimester of pregnancy as predictors of unfavourable obstetric outcomes at Hospital Universitario Nuestra Señora de Candelaria

Muchos estudios han documentado la asociación entre valores bajos de PAPP-A y β-hCG en el suero materno durante el primer trimestre, así como efectos materno-fetales adversos.Para valorar dicha relación, en nuestro medio se llevó a cabo un análisis retrospectivo de casos y controles anidado en una cohorte de pacientes con embarazo único en quienes se realizó el cribado del primer trimestre entre 2017 y 2018. Se consideraron casos aquellas pacientes con niveles de MoM PAPP-A y/o β-hCG iguales o inferiores al percentil 5, y como controles a una muestra aleatorizada de pacientes con niveles séricos por encima de dicho percentil.El análisis de nuestros resultados demostró que en los grupos con niveles bajos de MoM PAPP-A y MoM β-hCG se observó un mayor riesgo de desarrollar crecimiento intrauterino restringido que en el grupo control (OR: 2,7 y 3,17, respectivamente). En el grupo MoM PAPP-A≤p5 también se obtuvo un riesgo 3,8 veces superior de estados hipertensivos del embarazo (IC: 1,94-7,83) y 7,9 veces mayor de muerte fetal anteparto (IC:1,09-217,4). Estas dos variables no resultaron estadísticamente significativas en el grupo MoM β-hCG ≤p5.Nuestros hallazgos confirmaron que los niveles bajos de PAPP-A y β-hCG en el suero de las gestantes se asoció con un riesgo elevado de desarrollar complicaciones obstétricas, por lo que podrían utilizarse para la detección precoz de las mismas y prevención de malos resultados obstétricos.

Many studies have documented the association between low PAPP-A and β-hCG values in maternal serum during the first trimester and adverse maternal-foetal effects.To assess this relationship a retrospective analysis of cases and controls was carried out, based on a cohort of patients with a single pregnancy who underwent first-trimester screening between 2017 and 2018. For the group of cases, patients with MoM levels PAPP-A and/or β-hCG equal to or below the 5th percentile were selected. The control group was obtained by making a randomized selection of all patients with MoM PAPP-A levels and/or β-hCG above that percentile.The analysis of our results showed that in groups with low levels of MoM PAPP-A and MoM β- hCG, we observed a higher risk of developing restricted intrauterine growth than in the control group (OR: 2.7 and 3.17, respectively). In the MoM PAPP-A ≤p5 group we also obtained a 3.8-foldhigher risk of global hypertensive states of pregnancy (CI: 1.94-7.83) and 7.9-fold higher risk of antepartum foetal death (CI: 1.09- 217.4). These two variables were not statistically significant in the MoM β-hCG ≤p5 group.Our findings confirmed that low levels of PAPP-A and β-hCG in the serum of pregnant women are associated with a high risk of developing obstetric complications, so they could be used for their early detection and the prevention of poor obstetric results.

Solid-Density Ion Temperature from Redshifted and Double-Peaked Stark Line Shapes.

Heß spectral line shapes are important for diagnosing temperature and density in many dense plasmas. This work presents Heß line shapes measured with high spectral resolution from solid-density plasmas with minimized gradients. The line shapes show hallmark features of Stark broadening, including quantifiable redshifts and double-peaked structure with a significant dip between the peaks; these features are compared to models through a Markov chain Monte Carlo framework. Line shape theory using the dipole approximation can fit the width and peak separation of measured line shapes, but it cannot resolve an ambiguity between electron density n_{e} and ion temperature T_{i}, since both parameters influence the strength of quasistatic ion microfields. Here a line shape model employing a full Coulomb interaction for the electron broadening computes self-consistent line widths and redshifts through the monopole term; redshifts have different dependence on plasma parameters and thus resolve the n_{e}-T_{i} ambiguity. The measured line shapes indicate densities that are 80-100% of solid, identifying a regime of highly ionized but well-tamped plasma. This analysis also provides the first strong evidence that dense ions and electrons are not in thermal equilibrium, despite equilibration times much shorter than the duration of x-ray emission; cooler ions may arise from nonclassical thermalization rates or anomalous energy transport. The experimental platform and diagnostic technique constitute a promising new approach for studying ion-electron equilibration in dense plasmas.

All-Order Full-Coulomb Quantum Spectral Line-Shape Calculations.

Understanding how atoms interact with hot dense matter is essential for astrophysical and laboratory plasmas. Interactions in high-density plasmas broaden spectral lines, providing a rare window into interactions that govern, for example, radiation transport in stars. However, up to now, spectral line-shape theories employed at least one of three common approximations: second-order Taylor treatment of broadening operator, dipole-only interactions between atom and plasma, and classical treatment of perturbing electrons. In this Letter, we remove all three approximations simultaneously for the first time and test the importance for two applications: neutral hydrogen and highly ionized magnesium and oxygen. We found 15%-50% change in the spectral line widths, which are sufficient to impact applications including white-dwarf mass determination, stellar-opacity research, and laboratory plasma diagnostics.

INTRODUCCIÓN: La reciente pandemia de COVID-19 ha representado la utilización por parte de los profesionales de la salud de diferentes equipos de protección individual (EPI), lo que ha dado lugar a la aparición de lesiones cutáneas asociadas a los mismos (LC-EPI). Conocer la epidemiología, las características y los factores relacionados con el uso de los diferentes tipos de EPI y la prevención y el tratamiento de las LC-EPI puede ser muy útil para comprender el alcance del problema y definir estrategias para su prevención y tratamiento en posibles pandemias futuras. MÉTODOS: Estudio transversal realizado por el Grupo Nacional para el Estudio y Asesoramiento en Úlceras por Presión y Heridas Crónicas (GNEAUPP) en el ámbito geográfico del Estado español, mediante una encuesta autoadministrada utilizando un cuestionario de Google Forms. El universo de estudio fueron profesionales de la salud, de cualquier disciplina y nivel asistencial o tipo de institución que habían estado en contacto con pacientes o sospechosos de COVID-19 y habían utilizado EPI durante la primera ola de la pandemia de COVID-19 en España. RESULTADOS: Se obtuvieron 2078 cuestionarios, el 75,5% de enfermeras, el 10,79% de técnicos en cuidados auxiliares de enfermería (TCAE) y el 6,6% de médicos. De los respondedores, el 84,7% eran mujeres y el 15,3% hombres con una edad media de 43,7 años. En el 18,2% de los casos, la institución del profesional contaba con un protocolo para la prevención de las LC-EPI, en el 10,2% el profesional no sabía si existía y en el 71,3% restante la institución no contaba con dicho protocolo. El 29,9% de los profesionales utilizaba siempre algún producto de prevención de LC-EPI y el 25,3% en ocasiones. El 52,4% de los encuestados informó haber presentado al menos una LC-EPI, de los cuales el 39% había presentado una, el 35,8% dos, el 14,3% tres, el 2,2% cuatro y el 8,6% más de cuatro. En relación con el tipo de lesiones, el 74,3% fueron definidas como lesiones por presión (LPP), el 11% como lesiones por fricción (LF), el 8,5% como lesiones combinadas o multicausales (LCMC) y el 6,1% como lesiones cutáneas asociadas a la humedad (LESCAH). La duración media de las lesiones incidentes fue de 11,6 días (9,7 días para las LPP, 10,2 días para las LF, 19,9 días para las LCMC y 19,4 días para las LESCAH). En el artículo se presenta información más detallada por tipo de dispositivo causante, tipología y gravedad de las lesiones por dispositivo, así como las medidas preventivas utilizadas

INTRODUCTION: The recent COVID-19 pandemic has represented the use by health care professionals (HCP) of different personal protective equipment (PPE), resulting in the appearance of skin injuries associated with PPE (PPE-SI). Knowing the epidemiology, characteristics and factors related to the use of different types of PPE and the prevention and treatment of PPE-SI can be very useful to understand the scope of the problem and to define strategies for its prevention and treatment in possible future pandemics. METHODS: To this end, the GNEAUPP proposed the performance of a cross-sectional study, in the geographical area of the Spanish state, by means of a self-administered survey using a Google forms questionnaire. The study universe was HCP, from any discipline and from any level of care or type of institution with patients who have been in contact with COVID-19 patients or COVID-19 suspects and have used PPE during the first wave of the COVID-19 pandemic in Spain. MAIN RESULTS: We obtained 2078 questionnaires, 75.5% from nurses, 10.79% from nurse aids, and 6.6% from physicians. Of these, 84.7% were women and 15.3% were men with an average age of 43.7 years. In 18.2% of the cases the institution of the professional had a protocol for the prevention of PPE-SI, in 10.2% the professional did not know if it existed or not and in the remaining 71.3% the institution did not have such a protocol. 29.9% of the professionals always used some prevention product and 25.3% sometimes. 52.4% of respondents reported having submitted at least one PPE-SI, of which 39% had submitted one, 35.8% two, 14.3% three, 2.2% four and 8.6% more than four. In relation to PPE-SI, 74.3% were defined as pressure injuries (PI), 11% were friction injuries (FI), 8.5% were combined or multicausal injuries (CMCI) and 6.1% were skin injuries associated with moisture (MASI). The mean duration of incident injuries was 11.6 days (9.7 days for PI, 10.2 days for FI, 19.9 days for CMCI and 19.4 days for MASI). More detailed Information is presented in the paper by type of device causing, typology and severity of injuries per device as well as preventive measures used

Assessment of children in the autistic spectrum disorder that carry the Thr92Ala-DIO2 polymorphism.

INTRODUCTION: A polymorphism in the type 2 deiodinase (Thr92Ala-DIO2) gene has been associated with behavioral and cognitive dysfunction as well as neurodegeneration and oxidative stress in the central nervous system. OBJECTIVE: To test whether the minor allele (Ala92) frequency (MAF) is increased in children in the autism spectrum disorder (ASD), and whether carriers of the minor allele exhibit more severe symptoms and/or worse adaptive behavior. STUDY DESIGN: ASD children were evaluated at baseline and yearly throughout the study by psychologists using the following tools: autism behavior checklist, Vineland Adaptative Behaviour Scales II, non-verbal intelligence test SON-R 21/2-7, SON-R 6-40, Weschler scale for intelligence, and autism treatment evaluation checklist. SETTINGS: Academic outpatient mental health facility in Sao Paulo, Brazil. PARTICIPANTS: ASD boys and girls younger than 18 years of age. 132 consecutive ASD children, mostly boys (~ 80%); ~ 50% was classified as verbal. Exclusion criteria were coexistence of sensory and/or physical impairment, or any associated genetic syndromes. RESULTS: Median follow-up was for an uninterrupted period of 937 days (139-1375 days), which did not vary significantly among the genotypes. The MAF was 47% in ASD patients vs. 51% in a local reference population with similar ethnic background; the clinical severity and progression were not affected by the minor allele. Carriers of the minor allele exhibited higher adaptive behavior in the domains "daily living skills" and "communication", which correlated positively with the dose of the minor allele. CONCLUSION: The MAF is not different in ASD children, but carriers of the Thr92Ala-DIO2 polymorphism exhibited higher adaptive behavior.

[The effects of pharmacological treatment with stimulants on circadian activity patterns in children with attention deficit hyperactivity disorder]. / Efectos del tratamiento farmacológico estimulante sobre los patrones de actividad circadiana en niños con trastorno por déficit de atención/hiperactividad.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders in childhood. The nuclear symptoms of ADHD are treated with stimulant medication such as methylphenidate; however, there's a lot of controversy regarding its side effects. AIMS: To analyse the activity patterns in children with ADHD during a period of 24 hours for seven days, before and after taking pharmacological treatment with stimulants (methylphenidate) and observe the differences between the different presentations of ADHD (inattentive and combined subtype). PATIENTS AND METHODS: A total of 30 children and adolescents (newly diagnosed with ADHD according to DSM-IV). Analyses were carried out through actigraphy, an instrument that allows us to monitor body movements by analysing movement patterns and differences between sleep and wakefulness. RESULTS: There were significant differences before and after treatment showing higher activity levels in patients with ADHD before treatment, and a decrease in this situation after taking pharmacological treatment. There are also differences between inattentive and combined subtype, showing the last group, higher activity levels. CONCLUSIONS: The level of activation presented by ADHD subjects is higher before taking stimulant treatment, influencing circadian patterns, sleep and quality of life. Pharmacological treatments help to decrease the level of activation.

TITLE: Efectos del tratamiento farmacológico estimulante sobre los patrones de actividad circadiana en niños con trastorno por déficit de atención/hiperactividad.Introducción. El trastorno por déficit de atención/hiperactividad (TDAH) es uno de los trastornos mentales más comunes en la infancia. Los síntomas nucleares del TDAH se tratan con estimulantes como el metilfenidato; aun así, existe mucha controversia respecto a sus efectos secundarios. Objetivos. Analizar los patrones de actividad en niños con TDAH durante un período de 24 horas durante siete días, antes y después de tomar tratamiento farmacológico estimulante (metilfenidato), y observar si existen diferencias entre las diferentes presentaciones del trastorno (subtipo inatento y combinado). Pacientes y métodos. Un total de 30 niños y adolescentes (recién diagnosticados de TDAH según los criterios diagnósticos del DSM-IV) fueron evaluados a través de un actígrafo, un instrumento que permite monitorizar los movimientos corporales analizando los patrones de movimiento y las diferencias entre sueño y vigilia. Resultados. Existen diferencias significativas antes y después de realizar el tratamiento, con niveles de actividad más altos en los pacientes con TDAH antes de empezar el tratamiento y un decrecimiento de esta actividad tras el tratamiento farmacológico. También existen diferencias entre los subtipos inatento y combinado, y el último grupo muestra un nivel de actividad mayor. Conclusiones. El nivel de activación que presentan los sujetos con TDAH es mayor antes de tomar tratamiento, e influye en los patrones circadianos, el sueño y la calidad de vida. El tratamiento farmacológico ayuda a disminuir el nivel de activación.

Usefulness of a circumferential wound retractor in emergency colorectal surgery as a preventive measure for surgical site infection. Alexis O-Ring® and emergency surgery. / Utilidad del separador circunferencial para herida en cirugía colorrectal de urgencia como medida preventiva para infección del sitio quirúrgico. El Alexis O-Ring® y la cirugía de urgencia.

INTRODUCTION AND AIMS: More than 20% of healthcare-associated infections correspond to those at surgical sites, and there is a higher incidence of infections in colorectal surgery due to the associated bacterial load. Surgical wound protectors are designed to prevent contamination and mechanical trauma. Our aim was to demonstrate the usefulness of a circumferential wound retractor/protector for the prevention of surgical site infections (SSIs) in emergency colorectal surgery. METHODS: Forty-one patients that underwent emergency open surgery at a tertiary care hospital were randomized into 2 groups: 20 cases without the retractor (group A) and 21 cases with the retractor (group B). Subjects were assigned to a group in a 1:1 randomization allocation ratio. The chi-square and Fisher's exact tests were employed for the quantitative variables, and the statistical analysis was performed using the IBM Statistical Package for the Social Sciences software for Mac, version 16.0 (IBM SPSS Inc., Chicago, IL, USA). RESULTS: The SSI rate was 17%. Six group A patients developed SSI versus one group B patient. The use of a circumferential wound retractor/protector was statistically significant for the prevention of surgical wound infections, with a P=.031 and an OR of 8.5. In addition, preoperative blood glucose levels below 200mg/dl provided a 3.2-times higher protective effect, compared with glucose levels above 200mg/dl. CONCLUSIONS: In the present prospective randomized pilot study, the use of the circumferential wound retractor/protector significantly decreased the likelihood of SSI in emergency colorectal surgery.

Generation and characterization of human induced pluripotent stem cells (iPSCs) from hand osteoarthritis patient-derived fibroblasts.

Knowledge and research results about hand osteoarthritis (hOA) are limited due to the lack of samples and animal models of the disease. Here, we report the generation of two induced pluripotent stem cell (iPSC)-lines from patients with radiographic hOA. Furthermore, we wondered whether these iPSC-lines carried single nucleotide polymorphisms (SNPs) within genes that have been associated with hOA. Finally, we performed chondrogenic differentiation of the iPSCs in order to prove their usefulness as cellular models of the disease. We performed a non-integrative reprogramming of dermal fibroblasts obtained from two patients with radiographic rhizarthrosis and non-erosive hOA by introducing the transcriptional factors Oct4, Sox2, Klf4 and c-Myc using Sendai virus. After reprogramming, embryonic stem cell-like colonies emerged in culture, which fulfilled all the criteria to be considered iPSCs. Both iPSC-lines carried variants associated with hOA in the four studied genes and showed differences in their chondrogenic capacity when compared with a healthy control iPSC-line. To our knowledge this is the first time that the generation of iPSC-lines from patients with rhizarthrosis and non-erosive hOA is reported. The obtained iPSC-lines might enable us to model the disease in vitro, and to deeper study both the molecular and cellular mechanisms underlying hOA.

Computing the Fukui Function in Solid-State Chemistry: Application to Alkaline Earth Oxides Bulk and Surfaces.

Fukui functions (FFs) are chemical descriptors that are useful to explain the reactivity of systems toward electron transfer. Whereas they have been widely employed for molecules, their application to extended systems is scarce. One of the reasons for the limited development of such analysis in solids is the improper evaluation of FFs in the usual computational approaches based on density functional theory and periodic boundary conditions. In this work we compare the available approaches and propose a new method based on the interpolation of partially charged systems that mitigates some of the problems encountered. We discuss the reactivity of alkaline earth oxides (MgO, CaO, SrO, and BaO) in terms of the FF analysis, providing a robust way to account for the higher reactivity of surface oxygen sites compared with bulk sites.

Discusión y Conclusiones: Se concluye que la sintomatología depresiva se relaciona con el automanejo de la enfermedad de la siguiente manera: a mayor automanejo menor sintomatología de depresión, o a mayor sintomatología depresiva menor automanejo; dicha relación confirma que ambas variables se afectan mutuamente y/o mantienen una relación estrecha.

Abstract Introduction: Persons with diabetes and hypertension frequently suffer from depression as well, a situation which contributes to an inadequate management of the condition in terms of medication, medical consultations, signs, and decision making. Objective: To identify the relationship between general self-management and depression symptoms in persons with diabetes and hypertension. Method: This is a transversal and correlational study with a sample of 205 patients, 100 with a main diagnosis of diabetes, and 105 with a main diagnosis of hypertension. The sampling process was non-probabilistic and by convenience. Descriptive statistics, including Pearson's r were calculated. The Partners in Health (PIH) and Patient Health Questionnaire (PHQ-8) instruments were administered. Results: A statistically significant correlation between depression symptoms and diabetes and hypertension self-management was found (r=-0.308 ρ<0.001). Discussion and conclusions: Depression symptoms were related to how diabetes and hypertension are self-managed in a way that, the more self-management, the less depression symptoms, or the more depression symptoms, the less self-management.

Effect of Electron Capture on Spectral Line Broadening in Hot Dense Plasmas.

Accurate calculation of spectral line broadening is important for many hot, dense plasma applications. However, calculated line widths have significantly underestimated measured widths for Δn=0 lines of Li-like ions, which is known as the isolated-line problem. In this Letter, scrutinization of the line-width derivation reveals that the commonly used expression neglects a potentially important contribution from electron-capture. Line-width calculations including this process are performed with two independent codes, both of which removed the discrepancies at temperatures below 10 eV. The revised calculations also suggest the remaining discrepancy scales more strongly with electron temperature than the atomic number as was previously suggested.

SEOM clinical guideline on hereditary colorectal cancer (2019).

In the last 2 decades, clinical genetics on hereditary colorectal syndromes has shifted from just a molecular characterization of the different syndromes to the estimation of the individual risk of cancer and appropriate risk reduction strategies. In the last years, new specific therapies for some subgroups of patients have emerged as very effective alternatives. At the same time, germline multigene panel testing by next-generation sequencing (NGS) technology has become the new gold standard for molecular genetics.

Abstract Introduction: Considering the priority regarding the attention of non transmissible diseases, the World Health Organization proposed the Chronic Care Model which, by encompassing self-management as one main element, is intended to address these diseases. Objective: To identify predictor variables related to behavior on self-management among patients with Diabetes Mellitus, Hypertension, and Obesity. Methods: The intentional and non probabilistic simple included 386 patients from the Health Secretariat in Tamaulipas, Mexico (Ciudad Victoria and Tampico). The study design was non experimental and transversal. Results: About half (42.2%) of the participants with Chronic Non Transmissible diseases referred having depressive disorder ranging from mild to severe. Regarding the BMI, 33.2% showed overweight. Moreover, 36.8% perceived some degree of family dysfunction. A Multiple Linear Regression was calculated. The model indicated that there were seven predictors of the behavior on self-management (explained variance R2 =.325); being self-efficacy the most important (β=38), and perceived social support the lowest in load (β=.10). Conclusions: These predictors represent important elements to consider when building on the knowledge and understanding the behavior related to self-management, an area which is highlighted in the Chronic Care Model of the World Health Organization, particularly within nursing.

Sleep disordered breathing and nocturnal hypoxemia are very prevalent in a lung cancer screening population and may condition lung cancer screening findings: results of the prospective Sleep Apnea In Lung Cancer Screening (SAILS) study.

OBJECTIVE: Obstructive sleep apnea (OSA) can influence the appearance and proliferation of some tumors. The Sleep Apnea In Lung Cancer Screening (SAILS) study (NCT02764866) evaluated the prevalence of OSA and nocturnal hypoxemia in a high-risk population enrolled in a lung cancer screening program. METHODS: This was a prospective study of the prevalence of OSA in a lung cancer screening program. Subjects met the National Lung Screening Trial (NLST) age and smoking criteria (age 55-75 years; pack-years >30). Participants in the study were offered annual screening with low-dose computed tomography (LDCT) and pulmonary function testing, as well as home sleep apnea testing (HSAT) and a sleep-specific questionnaire. Sleep study-related variables, symptoms, and epidemiologic data were recorded. RESULTS: HSAT was offered to 279 subjects enrolled in our lung cancer screening program. HSAT results were available for 236 participants (mean age 63.6 years; mean tobacco exposure: 45 pack-years), of whom 59% were male and 53% were active smokers. Emphysema (74%) and chronic obstructive pulmonary disease (COPD) (62%) were common and in most cases mild in severity. OSA, including moderate to severe disease, was very common in this patient population. AHI distributions were as follows: AHI <5 (22.5%); 5-15 (36.4%); 15-30 (23.3%); and >30 (17.8%). Nocturnal hypoxemia (T90) (p = 0.003), diffusing capacity for carbon monoxide (DLCO) (p = 0.01), tobacco exposure (p = 0.024), and COPD (p = 0.023) were associated with OSA severity. Positive screening findings (nodules ≥6 mm) were associated with nocturnal hypoxemia on multivariate analysis adjusted for confounders (OR = 2.6, 95% CI = 1.12-6.09, p = 0.027). CONCLUSION: Moderate to severe OSA is very prevalent in patients enrolled in a lung cancer screening program. Nocturnal hypoxemia more than doubles the risk of positive screening findings.

Induced pluripotent stem cells for cartilage repair: current status and future perspectives.

The establishment of cartilage regenerative medicine is an important clinical issue, but the search for cell sources able to restore cartilage integrity proves to be challenging. Human mesenchymal stromal cells (MSCs) are prone to form epiphyseal or hypertrophic cartilage and have an age-related limited proliferation. On the other hand, it is difficult to obtain functional chondrocytes from human embryonic stem cells (ESCs). Moreover, the ethical issues associated with human ESCs are an additional disadvantage of using such cells. Since their discovery in 2006, induced pluripotent stems cells (iPSCs) have opened many gateways to regenerative medicine research, especially in cartilage tissue engineering therapies. iPSCs have the capacity to overcome limitations associated with current cell sources since large numbers of autologous cells can be derived from small starting populations. Moreover, problems associated with epiphyseal or hypertrophic-cartilage formation can be overcome using iPSCs. iPSCs emerge as a promising cell source for treating cartilage defects and have the potential to be used in the clinical field. For this purpose, robust protocols to induce chondrogenesis, both in vitro an in vivo, are required. This review summarises the recent progress in iPSC technology and its applications for cartilage repair.

Flea market finds and global exports: Four multistate outbreaks of human Salmonella infections linked to small turtles, United States-2015.

Zoonotic transmission of Salmonella infections causes an estimated 11% of salmonellosis annually in the United States. This report describes the epidemiologic, traceback and laboratory investigations conducted in the United States as part of four multistate outbreaks of Salmonella infections linked to small turtles. Salmonella isolates indistinguishable from the outbreak strains were isolated from a total of 143 ill people in the United States, pet turtles, and pond water samples collected from turtle farm A, as well as ill people from Chile and Luxembourg. Almost half (45%) of infections occurred in children aged <5 years, underscoring the importance of the Centers for Disease Control and Prevention recommendation to keep pet turtles and other reptiles out of homes and childcare settings with young children. Although only 43% of the ill people who reported turtle exposure provided purchase information, most small turtles were purchased from flea markets or street vendors, which made it difficult to locate the vendor, trace the turtles to a farm of origin, provide education and enforce the United States federal ban on the sale and distribution of small turtles. These outbreaks highlight the importance of improving public awareness and education about the risk of Salmonella from small turtles not only in the United States but also worldwide.

Effect of feed intake level and dietary protein content on the body temperature of pigs housed under thermo neutral conditions.

Feed intake and diet composition appear to affect the body temperature of pigs. Two trials were conducted to analyse the effect of feed intake level and dietary protein content on the intestinal temperature (IT) of pigs housed under thermo neutral conditions. Ten pigs (64.1 ± 1.3 kg initial body weight) fitted with an ileal cannula were used. A thermometer set to register the IT at 5-min intervals was implanted into the ileum through the cannula. In both trials, the ambient temperature ranged from 19.1 to 21.6°C and the pigs were fed at 07:00 and 19:00 hr (same amount each time). In trial 1, the pigs were fed daily 1.2 or 1.8 kg of a wheat-soybean meal diet. The IT followed a similar pattern along a 24-hr period regardless the feed intake level. The IT rapidly increased up to 0.61 and 0.74°C after the morning meal and up to 0.53 and 0.47°C after the evening meal in pigs fed 1.2 and 1.8 kg/d respectively. The postprandial IT was higher in pigs fed 1.8 kg after each meal (p < .05). In trial 2, pigs were fed daily 1.8 kg of a low (11%) or a high (22%) crude protein diet. The IT followed a similar pattern along the 24-hr period regardless the dietary protein level. The postprandial IT did not differ between pigs fed the low protein or the high protein (p > .10). The IT rapidly increased up to 0.66 and 0.62°C after the morning meal in pigs fed the high- and low-protein diet (p < .05), but there was no change after the evening meal (p > .10). In conclusion, the feed intake level affected the IT of pigs housed under TN conditions, but the dietary protein content had no effect.

Esta enfermedad concierne a la familia, ya que los cambios en el estilo de vida del paciente demandan apoyo familiar, orientación en la toma de decisiones y acciones necesarias para el adecuado manejo de la enfermedad. Asociado a lo anterior, algunos estudios han demostrado los beneficios de un adecuado automanejo en enfermedades crónicas, que implica: adherencia al tratamiento, reconocer síntomas de la enfermedad, hábitos de alimentación saludable, ejercicio y visitas al médico. Objetivo: Analizar la relación entre el automanejo y la percepción de funcionalidad familiar en personas con diabetes tipo 2 que reciben atención en los centros de salud de la Jurisdicción n. 2 de Tampico, Tamaulipas, México. Métodos: Estudio transversal-correlacional, muestreo no probabilístico por conveniencia con una N = 100. Se aplicaron los instrumentos Partners in Health Scale y APGAR familiar. Resultados: Los resultados muestran una correlación significativa entre el APGAR familiar total y el índice de automanejo. Conclusiones: Con base en los resultados se concluye que la relación entre automanejo y percepción de funcionalidad familiar debe ser explorada con mayor detalle, ya que podría ser un elemento de suma importancia en el diseño de estrategias de combate a la diabetes, no exclusivamente desde la labor de la enfermería sino en colaboración con el equipo multidisciplinario de salud.

Introduction: Diabetes mellitus is one of the main health problems worldwide due to its high rates of prevalence, its costs to the economies, its complications, and its high rate of mortality. This illness also involves the family because the changes in the lifestyles of patients demand the support from the family, orientation on decisionmaking, and actions for an adequate management of the illness. In this regard, some studies have demonstrated the benefits of adequate self-management of chronic illness, which includes: adherence to treatments, acknowledgment of the symptoms, healthy diet habits, exercise, and regular visits to the medical personnel. Objective: To analyze the relationship between self-management and perception of family functionality among persons with type 2 Diabetes Mellitus who are receiving attention in the health centers of Jursidicción 2, Tampico, Tamaulipas, Mexico. Methods: This is a transversal and correlational study with not-probabilistic by convenience sampling involving 100 participants. The Partners in Health Scale and Family APGAR instruments were used. Results: Findings show a significant correlation between total family APGAR and the Self- Management index. Conclusions: Based on the results, it is concluded that the relationship between selfmanagement and perception of family functionality should be explored in greater detail because this knowledge could help in the design of strategies to address Diabetes Mellitus from a perspective of multidisciplinary health team.

Long-term effects of hydrogen sulfide on the anabolic-catabolic balance of articular cartilage in vitro.

Healthy cartilage maintenance relies on an equilibrium among the anabolic and catabolic processes in chondrocytes. With the onset of osteoarthritis (OA), increased interleukin (IL)-1ß levels induce an inhibition of the synthesis of extracellular matrix (ECM) proteins, as well as an increase in proteases. This eventually leads to a predominance of the catabolic phenotype and the progressive loss of articular cartilage. Hydrogen sulfide (H2S) is a small gaseous molecule recognized as the third endogenous gasotransmitter. When administered exogenously, it has shown anti-inflammatory and anti-catabolic properties in several in vitro and in vivo models. Here, OA cartilage disks were co-cultured in vitro with IL-1ß (5 ng/ml) and NaSH or GYY4137 (200 or 1000 µM) for 21 days. The ability of these two H2S-producing compounds to avoid long term extracellular matrix (ECM) destruction was evaluated. We used a glycosaminoglycan (GAG) quantification kit histology and immunohistochemistry (IHC) to evaluate matrix proteins degradation and matrix metalloproteinases (MMP) abundance. Through the GAGs quantification assay, safranin O (S-O) and toluidine blue (TB) stains, and keratan/chondroitin sulfate (KS/ChS) IHCs it was shown that co-stimulation with H2S-forming reagents effectively avoided GAGs destruction. Both Masson's trichrome (MT) stain and collagen (col) type II IHC, as well as aggrecan (agg) IHC demonstrated that not only were these proteins protected but even promoted, their abundance being higher than in the basal condition. Further, stains also demonstrated that positivity in the inter-territorial and intra-cellular for the different matrix components were rescued, suggesting that NaSH and GYY4137 might also have pro-anabolic effects. In addition, a clear protective effect against the increased MMPs levels was seen, since increased MMP3 and 13 levels were subsequently reduced with the co-stimulation with sulfide compounds. In general, GYY4137 was more effective than NaSH, and increasing the dose improved the results. This study demonstrates that H2S anti-catabolic effects, which had been previously proven in short-term (24-48 h) in vitro cellular models, are maintained over time directly in OA cartilage tissue.

Multistate Outbreak of Human Salmonella Typhimurium Infections Linked to Pet Hedgehogs - United States, 2011-2013.

Zoonotic Salmonella infections cause approximately 130 000 illnesses annually in the United States. Of 72.9 million US households owning at least one pet, five million own small mammals; 3000 hedgehogs were documented by USDA in USDA-licensed breeding facilities and pet stores in 2012. State health department collaborators and PulseNet, the national bacterial subtyping network, identified human infections of a Salmonella Typhimurium outbreak strain, which were investigated by CDC, USDA-APHIS and state public and animal health officials. A case was defined as an illness in a person infected with the outbreak strain identified between 1 December 2011 and 3 June 2013. Investigators collected information on patient exposures, cultured animal and environmental specimens for Salmonella, and conducted traceback investigations of USDA-licensed hedgehog facilities. There were 26 cases in 12 states. Illness onset dates ranged from 26 December 2011 to 8 April 2013. The median patient age was 15 years (range = <1-91 years); 58% were female. Among 23 persons with available information, 8 (35%) were hospitalized and one outbreak strain-associated death was reported. Of 25 patients with available information, 20 (80%) reported pet hedgehog contact in the week before illness onset. The outbreak strain was isolated from animal and environmental samples collected from three ill persons' homes in three states. Hedgehogs were purchased in geographically distant states from USDA-licensed breeders (10/17, 59%); a USDA-licensed pet store (1/17, 6%); unlicensed or unknown status breeders (3/17, 18%); and private individuals (3/17, 18%). Traceback investigations of USDA-licensed facilities did not reveal a single source of infection. Public and animal health collaboration linked pet hedgehog contact to human infections of Salmonella Typhimurium, highlighting the importance of a One Health investigative approach to zoonotic salmonellosis outbreaks. More efforts are needed to increase awareness among multiple stakeholders on the risk of illness associated with pet hedgehogs.
