Programa de vigilancia epidemiológica de trastornos dorso lumbares en conductores de vehículos operativos de una Empresa de Recolección de Residuos Solido
El presente estudio de investigación se estableció con el objetivo de Diseñar un programa
de vigilancia epidemiológica en conductores de vehículos operativos de la empresa de
recolección de residuos sólidos, mediante estrategias de prevención, control y seguimientos, para
mantener y mejorar las condiciones de salud de los trabajadores.
El enfoque del tipo de Investigación empleada es Cualitativa, se tuvo una población de 35
conductores de la parte operativa de la empresa de recolección de residuos sólidos, donde se
pudo determinar que estos presentan dolores en la espalda y zona lumbar, se realizó un muestreo
por conveniencia, constituido por 35 conductores, los instrumentos utilizados fueron: formularios
de entrevista y de encuesta a los conductores, Horarios de las Actividades de Recolección.
En otro aspecto, indica que el exceso de trabajo y largas jornadas laborales son factores
que inciden en el dolor lumbar; Hace una referencia de las estadísticas en donde concluye que las
altas demandas laborales presentan mayor riesgo de padecimiento de lumbalgias en comparación
con labores de demanda media.
fue necesario aplicar una investigación Descriptiva con los aspectos más característicos,
distintivos y particulares de las situaciones que rodean las causas de lesiones osteomusculares.
En esta investigación como paso fundamental es la caracterización de la población con
sintomatología asociada a trastornos osteomusculares, los datos aquí relacionados serán
recolectados para propósitos de esta investigación en un punto específico en el tiempo, puesto
que por el alcance de la investigación y su limitante de tiempo no permite una nueva recolección
de datos, resultados de las evaluaciones médicas ocupacionales con énfasis sistema O-M,
Genero, edad, estado civil, nivel educativo, grupo sanguíneo, antecedentes familiares,
antecedentes de enfermedades personales, Índice de Masa Corporal (IMC) y hábitos.
Los 35 conductores fueron evaluados con respecto a estos factores mediante cuestionario,
y el resultado fue que el 71.4% de estos conductores presentaba trastorno dorso lumbar y que,
10
entre los probables factores de riesgo analizados, solo el número de horas de trabajo se
correlacionó significativamente con la presencia de trastorno dorso lumbar.
Se recomienda a todos los conductores: realizar educación en higiene postural corporal,
manipulación manual de cargas y programa de pausa activa, desarrollo y supervisión del
programa de pausa activa entre los empleados.This research study was established with the objective of Designing an epidemiological
surveillance program in drivers of operational vehicles, through prevention, control and
monitoring strategies, to maintain and improve the health conditions of workers.
The approach of the type of Research used is Qualitative, there was a population of 35
drivers of the operational part of the solid waste collection company, where it was possible to
determine that these have pains in the back and lower back, a sampling for convenience,
consisting of 35 drivers, the instruments used were: interview and survey forms to drivers ,
Hours of Collection ActivitiesIn another aspect, it indicates that excess work and long
working hours are factors that affect low back pain; It makes a reference to the statistics where it
concludes that high labor demands present a greater risk of suffering from low back pain
compared to medium demand jobs.
it was necessary to apply a descriptive investigation with the most characteristic,
distinctive and particular aspects of the situations surrounding the causes of musculoskeletal
injuries.
In this research, as a fundamental step is the characterization of the population with
symptoms associated with musculoskeletal disorders, the data related here will be collected for
the purposes of this research at a specific point in time, since due to the scope of the research and
its limitation of Time does not allow a new data collection, results of occupational medical
evaluations with emphasis on OM system, Gender, age, marital status, educational level, blood
group, family history, history of personal illnesses, Body Mass Index (BMI) and habits.
12
The 35 drivers were evaluated with respect to these factors by means of a questionnaire,
and the result was that 71.4% of these drivers had thoracolumbar disorder and that, among the
probable risk factors analyzed, only the number of hours of work was significantly correlated
with the presence of dorsolumbar disorder.
It is recommended for all drivers: to carry out education in body postural hygiene, manual
handling of loads and an active break program, development and supervision of the active break
program among employees.Introducción

Pregnancy in Chronic Kidney Disease: Need for Higher Awareness. A Pragmatic Review Focused on What Could Be Improved in the Different CKD Stages and Phases
Pregnancy is possible in all phases of chronic kidney disease (CKD), but its management may be difficult and the outcomes are not the same as in the overall population. The prevalence of CKD in pregnancy is estimated at about 3%, as high as that of pre-eclampsia (PE), a better-acknowledged risk for adverse pregnancy outcomes. When CKD is known, pregnancy should be considered as high risk and followed accordingly; furthermore, since CKD is often asymptomatic, pregnant women should be screened for the presence of CKD, allowing better management of pregnancy, and timely treatment after pregnancy. The differential diagnosis between CKD and PE is sometimes difficult, but making it may be important for pregnancy management. Pregnancy is possible, even if at high risk for complications, including preterm delivery and intrauterine growth restriction, superimposed PE, and pregnancy-induced hypertension. Results in all phases are strictly dependent upon the socio-sanitary system and the availability of renal and obstetric care and, especially for preterm children, of intensive care units. Women on dialysis should be aware of the possibility of conceiving and having a successful pregnancy, and intensive dialysis (up to daily, long-hours dialysis) is the clinical choice allowing the best results. Such a choice may, however, need adaptation where access to dialysis is limited or distances are prohibitive. After kidney transplantation, pregnancies should be followed up with great attention, to minimize the risks for mother, child, and for the graft. A research agenda supporting international comparisons is highly needed to ameliorate or provide knowledge on specific kidney diseases and to develop context-adapted treatment strategies to improve pregnancy outcomes in CKD women
Acute Kidney Injury in Pregnancy: The Need for Higher Awareness. A Pragmatic Review Focused on What Could Be Improved in the Prevention and Care of Pregnancy-Related AKI, in the Year Dedicated to Women and Kidney Diseases
Pregnancy-related acute kidney injury (pAKI), preeclampsia (PE), and the hypertensive disorders of pregnancy are closely related conditions, which are, in turn, frequently linked to pre-existing and often non-diagnosed chronic kidney disease (CKD). The current literature and research mainly underline the effects of pregnancy complications on the offspring; this review strongly emphasizes the maternal health as well. These conditions not only negatively affect pregnancy outcomes, but have a relevant effect on the future health of affected mothers and their children. Therefore, dedicated diagnostic and follow-up programs are needed, for optimizing materno-foetal health and reducing the impact of pregnancy-related problems in the mothers and in the new generations. This narrative review, performed on the occasion of the 2018 World Kidney Day dedicated to women's health, focuses on three aspects of the problem. Firstly, the risk of AKI in the hypertensive disorders of pregnancy (the risk is the highest in developing countries; however PE is the main cause of pregnancy related AKI worldwide). Secondly, the effect of AKI and the hypertensive disorders of pregnancy on the development of CKD in the mother and offspring: long-term risks are increased; the entity and the trajectories are still unknown. Thirdly, the role of CKD in the pathogenesis of AKI and the hypertensive disorders of pregnancy: CKD is a major risk factor and the most important element in the differential diagnosis; pregnancy is a precious occasion for early diagnosis of CKD. Higher awareness on the importance of AKI in pregnancy is needed to improve short and long term outcomes in mothers and children
Reconstructing the two right-handed neutrino model
In this paper we propose a low-energy parametrization of the two right-handed
neutrino model, and discuss the prospects to determine experimentally these
parameters in supersymmetric scenarios. In addition, we present exact formulas
to reconstruct the high-energy leptonic superpotential in terms of the
low-energy observables. We also discuss limits of the three right-handed
neutrino model where this procedure applies.Comment: 28 pages, 4 figures. Typos corrected, references adde
Whole Genome Sequence Analysis of Burkholderia contaminans FFH2055 Strain Reveals the Presence of Putative β-Lactamases
Burkholderia contaminans is a member of the Burkholderia cepacia complex (Bcc), a pathogen with increasing prevalence among cystic fibrosis (CF) patients and the cause of numerous outbreaks due to the use of contaminated commercial products. The antibiotic resistance determinants, particularly β-lactamases, have been poorly studied in this species. In this work, we explored the whole genome sequence (WGS) of a B. contaminans isolate (FFH 2055) and detected four putative β-lactamase-encoding genes. In general, these genes have more than 93% identity with β-lactamase genes found in other Bcc species. Two β-lactamases, a class A (Pen-like, suggested name PenO) and a class D (OXA-like), were further analyzed and characterized. Amino acid sequence comparison showed that Pen-like has 82% and 67% identity with B. multivorans PenA and B. pseudomallei PenI, respectively, while OXA-like displayed strong homology with class D enzymes within the Bcc, but only 22–44% identity with available structures from the OXA family. PCR reactions designed to study the presence of these two genes revealed a heterogeneous distribution among clinical and industrial B. contaminans isolates. Lastly, bla PenO gene was cloned and expressed into E. coli to investigate the antibiotic resistance profile and confers an extended-spectrum β-lactamase (ESBL) phenotype. These results provide insight into the presence of β-lactamases in B. contaminans, suggesting they play a role in antibiotic resistance of these bacteria.Fil: Degrossi, José J..

SSDSS IV MaNGA - Properties of AGN host galaxies
We present here the characterization of the main properties of a sample of 98
AGN host galaxies, both type-II and type-I, in comparison with those of about
2700 non-active galaxies observed by the MaNGA survey. We found that AGN hosts
are morphologically early-type or early-spirals. For a given morphology AGN
hosts are, in average, more massive, more compact, more central peaked and
rather pressurethan rotational-supported systems. We confirm previous results
indicating that AGN hosts are located in the intermediate/transition region
between star-forming and non-star-forming galaxies (i.e., the so-called green
valley), both in the ColorMagnitude and the star formation main sequence
diagrams. Taking into account their relative distribution in terms of the
stellar metallicity and oxygen gas abundance and a rough estimation of their
molecular gas content, we consider that these galaxies are in the process of
halting/quenching the star formation, in an actual transition between both
groups. The analysis of the radial distributions of the starformation rate,
specific star-formation rate, and molecular gas density shows that the
quenching happens from inside-out involving both a decrease of the efficiency
of the star formation and a deficit of molecular gas. All the intermediate
data-products used to derive the results of our analysis are distributed in a
database including the spatial distribution and average properties of the
stellar populations and ionized gas, published as a Sloan Digital Sky Survey
