Analysis of the Population Dynamics of Whitefly (Bemisia tabaci [Hemiptera: Aleyrodidae]) Under Greenhouse Conditions.

Whiteflies (Bemisia tabaci) represent an insect pest in horticulture. It serves as a vector for transmitting phytopathogens that inhibit the correct development of plants, affecting crop performance. In this research, whitefly population model was proposed to provide a tool that predicts the pest spread within a crop under greenhouse conditions. The analysis, calibration, and validation of the models, based on logistic functions, were implemented for the three stages (egg, nymph, and adult) of the life cycle of this organism. Temperature (°C), relative humidity (%), initial population (number/cm2), and Growing Degree-Day (GDD) were considered as input variables to describe each development stage. The statistical analysis for the model validation included the coefficient of determination (R2), the percentage standard error of prediction (%SEP), the average relative variance (AVR), and the efficiency coefficient (E). The first period for calibration consisted of 43 d (204.3 GDD), and the second period for validation consisted of 36 d (171.1 GDD). The model efficiently predicts the population growth for the egg, nymph, and adult stages since the values of R2 were 0.9856, 0.9918, and 0.9436, and the values of %SEP were 12.4, 11.9, and 75.1% for the egg, nymph, and adult stages, respectively. Moreover, the validation model obtained an R2 of 0.9287 for the egg stage, 0.9645 for the nymph stage, and 0.9884 for the adult stage. Meanwhile, the values of %SEP were 10.38, 16.89, and 32.59% for the egg, nymph, and adult stages, respectively. In both cases, the values suggest an adequate fit for the model.

[Information overload syndrome: a bibliographic review]. / Síndrome de la sobrecarga informativa: una revisión bibliográfica.

INTRODUCTION: We are living in the time of greatest dissemination of information in the history of the human race, and this excess of information has resulted in considering human attention as a scarce resource. Information overload is the situation in which the amount or intensity of information exceeds the individual's limited capacity for cognitive processing. OBJECTIVE: To describe the concept of information overload, its possible neurocognitive substrates, associated symptoms, causes, measures to avoid it, as well as its possible relationship with the internet and electronic devices. DEVELOPMENT: People respond differently to information overload, and this depends on individual factors as well as on the amount and characteristics of the informative stimulation. Some symptoms of information overload are: inefficient work, confusion, delay in making decisions, lack of critical evaluation of information, loss of control over information, refusal to receive communication, lack of general perspective, greater tolerance for error, anxiety, stress, etc. The limits of information processing capacity are probably conditioned by the limited metabolic energy that is distributed in the brain and remains constant regardless of the difficulty of the tasks. CONCLUSION: Attention is a limited cognitive function. In order to reduce the adverse effects of information overload, it is necessary to improve the personal management of our own cognitive resources and to understand their relationship with technology. Likewise, it is necessary to improve the handling of information through the organization, filtering and application of cognitive ergonomics design guidelines.

Adjunctive Rifampicin Increases Antibiotic Efficacy in Group A Streptococcal Tissue Infection Models.

Biofilm has recently been highlighted as a complicating feature of necrotizing soft tissue infections (NSTI) caused by Streptococcus pyogenes (i.e., group A Streptococcus [GAS]) contributing to a persistence of bacteria in tissue despite prolonged antibiotic therapy. Here, we assessed the standard treatment of benzylpenicillin and clindamycin with or without rifampin in a tissue-like setting. Antibiotic efficacy was evaluated by CFU determination in a human organotypic skin model infected for 24 or 48 h with GAS strains isolated from NSTI patients. Antibiotic effect was also evaluated by microcalorimetric metabolic assessment in in vitro infections of cellular monolayers providing continuous measurements over time. Adjunctive rifampin resulted in enhanced antibiotic efficacy of bacterial clearance in an organotypic skin tissue model, 97.5% versus 93.9% (P = 0.006). Through microcalorimetric measurements, adjunctive rifampin resulted in decreased metabolic activity and extended lag phase for all clinical GAS strains tested (P < 0.05). In addition, a case report is presented of adjunctive rifampin treatment in an NSTI case with persistent GAS tissue infection. The findings of this study demonstrate that adjunctive rifampin enhances clearance of GAS biofilm in an in vitro tissue infection model.

Relación del machismo con la aceptación de la diabetes mellitus tipo 2 en hombres adultos / Machismo relationship with type 2 diabetes mellitus acceptance among adult men / Relação do machismo com a aceitação do diabetes mellitus tipo 2 em homens adultos

RESUMEN Introducción La aceptación de la diabetes mellitus tipo 2 contribuye al apego del tratamiento y al control de la enfermedad. Pero se ha reportado que los hombres tienen menor aceptación al diagnóstico de este padecimiento. En los hombres mexicanos la no aceptación puede estar relacionada con el machismo. Objetivo Identificar la relación del machismo con la aceptación de la diabetes mellitus tipo 2. Metodología Se realizó un estudio transversal y correlacional. La población de interés fue de hombres con diabetes mellitus tipo 2 entre 20 y 59 años de edad registrados en centros de atención primaria del área metropolitana de Monterrey, Nuevo León, México. Se obtuvo una muestra de 121 participantes a través de un muestreo por conveniencia. Los instrumentos utilizados fueron el Inventario de Conformidad de las Normas Masculinas y la Escala Aceptación en DMT2. Para el análisis estadístico se empleó el programa SPSS versión 25; se realizó un modelo de regresión lineal múltiple. Resultados Los resultados señalan que los hombres con percepción de mayor machismo, jornadas laborales extensas y consumo elevado de cigarrillos aceptan menos el diagnóstico y la enfermedad de la diabetes mellitus tipo 2. Para las subdimensiones del machismo, la homofobia fue el mejor predictor de la aceptación o no de la diabetes mellitus tipo 2. Conclusiones El profesional de salud debe desarrollar programas para la aceptación de la diabetes mellitus tipo 2 en hombres de reciente diagnóstico que contribuyan a aceptar su enfermedad, y así, permitan mejorar el autocuidado, control glucémico y prevención de complicaciones.

ABSTRACT Introduction Accepting a diagnosis of type 2 diabetes mellitus contributes to the adher- ence to the treatment and control of the illness; however, it has been reported that men tend to have a lower acceptance of this diagnosis. Among Mexican men, in particular, this low acceptance could be related to their machismo. Objective To identify the relationship of machismo with the acceptance of a type 2 diabetes mellitus diagnosis. Methodology This is a transversal and correlational study. The population of interest were Mexican men diagnosed with type 2 diabetes mellitus between 20 and 59 years registered in centers of primary attention in the city of Monterrey, Mexico. The sample was constituted of 121 participants chosen by convenience. The instruments used were the Conformity to Masculine Norms Inventory and the Acceptance Scale for DM2. The statistical analysis and the multiple linear regression model were carried out using SPSS v25. Results Findings suggest that men who show machismo, who have long labor shifts, and who consume large quantities of cigarettes tend not to accept a diagnosis of type 2 diabetes mellitus. Regarding the subdimensions of the machismo construct, homophobia was the best predictor of accepting or not a diagnosis of type 2 diabetes mellitus. Conclusions Healthcare professionals should develop programs aimed at improving the acceptance attitude of a type 2 diabetes mellitus diagnosis among men, including those with machismo, in order to better manage self-care, glucose control, and also prevent complications.

Aryl hydrocarbon receptor interacting protein (AIP) significantly influences prognosis of pancreatic carcinoma.

INTRODUCTION: Aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor. Aryl hydrocarbon receptor interacting protein (AIP) in one of AHR ligands. The aim of this study is to analyze the prognostic influence of AIP in pancreatic carcinoma. MATERIAL AND METHODS: Retrospective case series with immunohistochemical analysis of AIP. We have estimated a multivariate Cox's model for the outcome (progression free and overall survival). RESULTS: 204 patients were included in the study. As expected prognosis was poor and 67.8% died of disease. As for AIP 9.8% of the cases showed nuclear staining of the epithelial tumor cells and 59.4% a cytoplasmic one. Stroma was stained in 53.1% of the cases. Univariate survival analysis revealed a significantly worse prognosis of patients with cytoplasmic AIP expression (stroma and epithelium), but nuclear expression was associated to a better prognosis. In the multivariate analysis stromal AIP expression was an independent prognosticator of progression free survival, together with pT stage, histological grade and history of diabetes. DISCUSSION: AIP Is a conserved cochaperone protein binding to many proteins. AIP has been proposed as a potential tumor suppressor gene. To date, no study has analyzed the immunohistochemical expression of AIP in pancreatic carcinoma. Our results indicate that both epithelial and stromal cytoplasmic expression of AIP is associated to bad prognosis, while nuclear translocation seems to improve prognosis. CONCLUSION: Although we must deepen into the complex signaling pathways underlying this potential association, our results open a way to inhibiting AHR as a potential target against pancreatic carcinoma.

Remote RF excitation for small-bore MR imager at 15.2 T.

We report a method for remote excitation of the RF signal for preclinical-equivalent ultra high field Magnetic Resonance Imaging (MRI). A parallel-plate waveguide together with a bio-inspired surface coil were used to perform remote excitation experiments to acquire images with a small-bore MR imager at 15.2 T. The imager bore size limits the RF coil transmitter dimensions, so the Gielis super-formula was used to design an RF coil with small dimensions. Electromagnetic simulations of the principal mode were run to study the waveguide filled with air and loaded with a saline solution-filled tube. Radiation patterns were also computed in a semi-anechoic chamber for the same scenarios as above. A saline solution-filled spherical phantom and a formaldehyde-fixed mouse phantom were used to acquire images. Radiation patterns showed an omnidirectional distribution with no side lobes, and a very smooth behaviour with almost no loss of information in the saline solution-filled tube and without. The theoretical wave impedance was calculated and compared with simulated results showing an excellent correspondence. Spherical phantom image data and simulation results of B1 were contrasted and showed an important correlation. Ex vivo mouse images were of high quality and exhibited clear delineation of anatomical structures. These imaging results are in very good agreement with the simulations. Numerical, theoretical and experimental results validate this approach, using a bio-inspired surface coil with a simple waveguide for preclinical small-bore MRI at ultra high field.

Primary resistance to integrase strand transfer inhibitors in Spain using ultrasensitive HIV-1 genotyping.

BACKGROUND: Transmission of resistance mutations to integrase strand transfer inhibitors (INSTIs) in HIV-infected patients may compromise the efficacy of first-line antiretroviral regimens currently recommended worldwide. Continued surveillance of transmitted drug resistance (TDR) is thus warranted. OBJECTIVES: We evaluated the rates and effects on virological outcomes of TDR in a 96 week prospective multicentre cohort study of ART-naive HIV-1-infected subjects initiating INSTI-based ART in Spain between April 2015 and December 2016. METHODS: Pre-ART plasma samples were genotyped for integrase, protease and reverse transcriptase resistance using Sanger population sequencing or MiSeq™ using a ≥ 20% mutant sensitivity cut-off. Those present at 1%-19% of the virus population were considered to be low-frequency variants. RESULTS: From a total of 214 available samples, 173 (80.8%), 210 (98.1%) and 214 (100.0%) were successfully amplified for integrase, reverse transcriptase and protease genes, respectively. Using a Sanger-like cut-off, the overall prevalence of any TDR, INSTI-, NRTI-, NNRTI- and protease inhibitor (PI)-associated mutations was 13.1%, 1.7%, 3.8%, 7.1% and 0.9%, respectively. Only three (1.7%) subjects had INSTI TDR (R263K, E138K and G163R), while minority variants with integrase TDR were detected in 9.6% of subjects. There were no virological failures during 96 weeks of follow-up in subjects harbouring TDR as majority variants. CONCLUSIONS: Transmitted INSTI resistance remains rare in Spain and, to date, is not associated with virological failure to first-line INSTI-based regimens.

Resumen Introducción: La prevalencia global de diabetes mellitus tipo 2 (DMT2) en los hombres es alta. Para el tratamiento de la enfermedad el hombre debe realizar acciones de autocuidado, por lo que es importante conocer factores relacionados con su cumplimiento. Objetivo: Identificar la relación entre variables demográficas, clínicas, la angustia, la depresión, la autoeficacia y su influencia sobre el autocuidado en hombres con DMT2. Métodos: Estudio transversal y correlacional, en una muestra de 96 hombres con DMT2, usuarios de 13 centros de salud. Los instrumentos utilizados fueron el cuestionario de acciones de cuidado en diabetes, la escala Self-Efficacy for Diabetes, la escala depresión (CES-D) y la escala angustia por diabetes (DDS). Resultados: El autocuidado se correlacionó de manera positiva con la autoeficacia y negativamente con la angustia por diabetes. Las variables que explicaron el autocuidado con el 47.7% de varianza fueron: la autoeficacia (β = .39), el consumo de alcohol (β = -.29), las horas sentado/parado (β= -.27), el tiempo de diagnóstico (β= -.22) y la edad (β =.18). Discusión: Los hombres tuvieron un bajo autocuidado y mantienen conductas de riesgo, lo cual puede atribuirse a sus creencias, estilo de vida o al tipo de trabajo que desempeñan. Conclusiones: Los resultados ofrecen evidencia sobre factores que influyen en el autocuidado de hombres con DMT2, que pueden orientar a los profesionales de enfermería en la atención del paciente. Se sugiere realizar investigaciones de enfermería en hombres, que contribuyan a mejorar la autoeficacia y el autocuidado.

Abstract Introduction: The global prevalence of type 2 diabetes mellitus among men is high; and these patients need to follow self-care routines. Therefore, knowing the factors which can affect their level of compliance is an important issue for nursing. Objective: To identify the relationship between demographic and clinical variables such as anguish and depression, and self-care efficacy in men suffering from type 2 diabetes mellitus. Methods: This a transversal and correlational study on a sample of 96 men with type 2 diabetes mellitus who were registered in 13 health centers. The instruments used were the Questionnaire of Actions of Care in Diabetes, the Self-Efficacy for Diabetes Scale (SED), the Mexico Center of Epidemiological Studies of Depression Scale (CES-D), and the Diabetes Distress Scale (DDS). Results: Self-care was positively correlated to self-efficacy, and negatively correlated to diabetes-related anguish and depression. Variables which accounted for 47.7% of the self-care variance were: self-efficacy (β = .39), alcohol consumption (β = -.29), number of hours sitting or standing (β= -.27), years of being diagnosed (β= -.22), and age (β =.18). Discussion: The sample demonstrated a low level of diabetes self-care which included risky behaviors. This attitude could be a result of the patients' beliefs, lifestyles, and/or type of job. Conclusions: The findings provide evidence on the factors which can influence self-care among men with type 2 diabetes. These results can orient nursing professionals while providing patient attention. Further related studies are suggested in order to help improve efficacy in type 2 diabetes self-care.

Sugere-se realizar pesquisas de enfermagem em homens, que contribuam a melhorar a autoeficácia e o autocuidado.

Necrotizing Sarcoid Granulomatosis: A Disease Not to be Forgotten.

Sarcoidosis is a systemic granulomatous disease of unknown aetiology characterised by the appearance of noncaseifying epithelioid granulomas in the affected organs, most commonly the lungs, skin, and eyes (Iannuzzi et al. 2007). Necrotizing Sarcoid Granulomatosis (NGS) is a rare and little-known form of disease, which also presents nodular lung lesions, and it shares pathologic and clinical findings with sarcoidosis, where the presence of necrosis may lead to misdiagnosis of tuberculosis (TB), leading to a consequent delay in treatment of the underlying entity (Chong et al. 2015). This is exactly what happened with the two cases that we present here.

Agreements and uncertainties in autologous haematopoietic stem cell mobilization and collection. A Spanish consensus document.

Although many experts position statements on autologous stem cell mobilization have been published, there are some aspects that are still under discussion. A Spanish Hematologist expert group was summoned to settle on agreements and uncertainties on PBSCs mobilization, including factors not always considered; as apheresis and cytometry key factors that determine a successful PBSC collection. This document reviews critical factors that define poor mobilizer patients and the tools to better collect the desired stem cells for a successful autologous haematopoietic stem cell transplant.

Splenic volume as a biomarker of hepatic damage after chemotherapy in patients with resected colorectal liver metastases (CRLM).

BACKGROUND: Chemotherapy-associated liver injury (CALI) is a matter of concern for hepatobiliary surgeons as it can entail postoperative liver failure after an extensive hepatectomy. Recent studies have taken special interest in liver function parameters which can correlate with CALI to decrease this adverse event. Therefore, the current study investigates the usefulness of splenic volume as a biomarker of CALI through a portal hypertension mechanism, in patients with colorectal liver metastases (CRLM). STUDY DESIGN: We carried out a study in patients with CRLM operated on between 2009 and 2014 in our center. All samples of healthy liver were graded for non-alcoholic fatty liver disease (NAFLD) and sinusoidal obstructive syndrome. Computarized tomography scans for spleen volumetry were analyzed for each patient at CRLM diagnosis, after neoadjuvant chemotherapy, 1 and 6 months after resection. RESULTS: A group of 65 consecutive patients with CRLM of large bowel adenocarcinoma submitted to liver resection were included. Patients receiving neoadjuvant chemotherapy had a greater spleen volume increase than those who did not receive treatment (p = 0.053), finding a statistically significant spleen growth in patients with NAFLD (p = 0.036). There was no correlation between spleen enlargement and postoperative complications or average stay. However, survival was decreased in patients with spleen growth and CALI. CONCLUSIONS: Patients who receive neoadjuvant chemotherapy for liver metastasis surgery have a greater splenic volume increase, which correlates with NAFLD and a lower survival.

Parenteral drug use as the main barrier to hepatitis C treatment uptake in HIV-infected patients.

OBJECTIVES: Our objective was to identify patient factors associated with being untreated for hepatitis C virus (HCV) infection in HIV-coinfected patients. METHODS: A prospective longitudinal study was carried out. HIV-infected patients with active chronic HCV infection included in the HERACLES cohort (NCT02511496) constituted the study population. The main study outcome was receipt of HCV direct-acting antiviral (DAA) treatment from 1 May 2015 to 1 May 2017. The population was divided into patients who were receiving HCV treatment during follow-up and those who were not. RESULTS: Of the 15 556 HIV-infected patients in care, 3075 (19.7%) presented with chronic HCV infection and constituted the study population. At the end of the follow-up, 1957 patients initiated HCV therapy (63.6%). Age < 50 years, absence of or minimal liver fibrosis, being treatment-naïve, HCV genotype 3 infection, being in the category of people who inject drugs using opioid substitutive therapy (OST-PWID), and being in the category of recent PWID were identified as significant independent risk factors associated with low odds of DAA implementation. When a multivariate analysis was performed including only the PWID population, both OST-PWID [odds ratio (OR) 0.552; 95% confidence interval (CI) 0.409-0.746) and recent PWID (OR 0.019; 95% CI 0.004-0.087) were identified as independent factors associated with low odds of treatment implementation. CONCLUSIONS: We identified factors, which did not include prioritization of a DAA uptake strategy, that limited access to HCV therapy. The low treatment uptake in several populations seriously jeopardizes the elimination of HCV infection in the coming years.

Robotic-assisted laparoscopic repair of rectovesical fistula after Hartmann's reversal procedure.

The case is of a 59-year-old male with history of severe ischemic colitis following emergent intervention for a ruptured infrarenal aortic aneurysm who subsequently underwent left hemicolectomy, partial proctectomy, and Hartmann colostomy. The patient later underwent reversal of the Hartmann colostomy with diverting ileostomy. The surgery was complicated by a right ureteral and posterior bladder injury that resulted in a large rectovesical fistula involving the right hemitrigone and right ureteral orifice. An attempt to repair the rectovesical fistula at an outside facility was unsuccessful. Then, he underwent a robotic-assisted laparoscopic repair of rectovesical fistula, including simple prostatectomy, excision of rectovesical fistulous tract, rectal closure, peritoneal and omental flap interposition, bladder neck reconstruction, vesicourethral anastomosis and right ureteral reimplantation. There were no intraoperative or postoperative complications, and the patient was discharged at postoperative day 4; cystoscopy at 6-week follow-up demonstrated a successful closure of the fistula, at which time the ureteral stents were removed.

Still a place for conventional histopathological analysis in the era of molecular medicine: predicting prognosis of resectable ductal pancreatic adenocarcinoma.

INTRODUCTION: Our aim is to find features that define prognosis in surgically resected ductal pancreatic adenocarcinoma readily accessible in everyday practice. MATERIALS AND METHODS: Longitudinal retrospective case series of pancreatic adenocarcinoma operated with a curative intent in a large tertiary hospital in Madrid between 2009 and 2015. RESULTS: 162 were enrolled. 40.8% survived less than 1 year. Multivariate Cox's regression model revealed that gender, presence of symptoms, T and N stage independently influenced progression-free survival, while overall survival was determined by gender, smoking, presence of symptoms and N stage. Logistic regression analysis revealed that only symptoms at diagnosis could predict death, while gender, symptoms, histopathological type, vessel invasion, T stage and necrosis could independently predict recurrence. DISCUSSION: Our series show that patients with symptomatic disease at the time of diagnosis and females showed a shorter progression-free and overall survival. We herein propose a regression model to predict outcome.

Piomiositis del músculo pectíneo. Descripción de un caso y revisión bibliográfica / Pectineus muscle pyomyositis. A case report and review of the literature

La piomiositis (PM) es una infección aguda bacteriana que afecta al músculo estriado, generalmente causada por Staphylococcus aureus y suele acompañarse de la formación de un absceso en el músculo. Esta entidad clínica fue descrita por primera vez en 1885 por Scriba1 como enfermedad endémica en los trópicos. En las últimas dos décadas se ha observado un incremento notable del número de casos en países de clima templado, probablemente asociado a un aumento de pacientes inmunodeprimidos. Las infecciones profundas de músculos pélvicos son difíciles de diagnosticar por ocasionar signos clínicos inespecíficos y que hacen pensaren otras patologías más comunes. Comunicamos el caso de una paciente de 33 años diabética que consultó por dolor inguinal acompañado de tumoración en la misma zona y fiebre de 4 días de evolución. Recibió tratamiento sintomático sin respuesta. La resonancia nuclear magnética pélvica fue compatible con piomiositis de músculo pectíneo. Recibió tratamiento antibiótico, evolucionando satisfactoriamente. La piomiositis es una entidad poco frecuente, que requiere un elevado índice de sospecha, para un adecuado diagnóstico y tratamiento, siendo la terapia antibiótica y drenaje en caso de absceso los pilares de éste último. Este tratamiento debe instaurarse de forma precoz, ya que su evolución puede ser potencialmente letal

Pyomyositis (PM) is an acute bacterial infection of skeletal muscle, usually caused by Staphilococcus Aureus and it is frenquently associated to a muscle abcess. This clinical entity was first described by Scriba1 at 1885 as a tropic endemic pathology. In the past two decades the number of cases at countries of temperate climate has rised notably due to the number of patients with inmunosuppression. Unfortunately, diagnosis of deep pelvic muscle infection is often delayed since they usually present with non-specific physical signs suggesting other more common diseases. The authors communicate a case of a diabetic33-year-old female who suffered inguinal acute pain and mass with history of fever since 4 days before. She initially received symptomatic treatment with no success. Pelvis magnetic resonance imaging showed pyomyositis of the piriformis muscle. Antibacterial treatment was administered, resulting in a good outcome. Pyomyositis is a rare condition that demands a high index of suspicion to make an adequate diagnosis and prompt treatment, including antibacterial treatment and drainage, particularly in case of abscess formation. This treatment should be established promptly since its outcome may be potentially lethal

Rhombohedral R3c to orthorhombic Pnma phase transition induced by Y-doping in BiFeO3.

In this work we study, by means of ab initio calculations, the structural, electronic and magnetic properties of Y-doped BiFeO3 compounds. We determine that there is a morphotropic phase boundary at an yttrium concentration of [Formula: see text], where the structure changes from R3c to Pnma. This structural transition is driven by the chemical pressure induced by the dopant. By analyzing the evolution of the oxygen octahedral tilts we find an enhanced antiferrodistortive distortion when increasing the Y-doping, together with a reduction of the ferroelectric distorsion, that gives rise to a smaller value of the electric polarization. These cooperative effects should lead to a larger canting of the Fe magnetic moments and to a larger ferromagnetic response in the R3c phase, as it is observed in the experiments.
