Quantum Computation of Hydrogen Bond Dynamics and Vibrational Spectra.

Calculating observable properties of chemical systems is often classically intractable and widely viewed as a promising application of quantum information processing. Here, we introduce a new framework for solving generic quantum chemical dynamics problems using quantum logic. We experimentally demonstrate a proof-of-principle instance of our method using the QSCOUT ion-trap quantum computer, where we experimentally drive the ion-trap system to emulate the quantum wavepacket dynamics corresponding to the shared-proton within an anharmonic hydrogen bonded system. Following the experimental creation and propagation of the shared-proton wavepacket on the ion-trap, we extract measurement observables such as its time-dependent spatial projection and its characteristic vibrational frequencies to spectroscopic accuracy (3.3 cm-1 wavenumbers, corresponding to >99.9% fidelity). Our approach introduces a new paradigm for studying the chemical dynamics and vibrational spectra of molecules and opens the possibility to describe the behavior of complex molecular processes with unprecedented accuracy.

Puntuación de trauma revisado como predictor de mortalidad intrahospitalaria en pacientes politraumatizados atendidos en el Hospital Belén de Trujillo, Perú

Objetivo: Determinar si el score de trauma revisado es predictor de mortalidad intrahospitalaria en pacientes politraumatizados atendidos en el Hospital Belén de Trujillo. Material y métodos: Se realizó un estudio observacional, analítico, retrospectivo, transversal de pruebas diagnósticas, se identificaron pacientes que fueron admitidos por politraumatismo y fueron hospitalizados en el Departamento de Cirugía General durante el periodo comprendido entre enero del 2017 a diciembre del 2021; en una muestra de 100 pacientes se evaluó la mortalidad. Resultados: La edad promedio fue 47,18 ± 20,40 vs 41,13 ± 18,37 en aquellos que fallecieron y sobrevivieron; el 55% y 63,33% de los fallecidos y sobrevivientes fueron varones en los grupos de estudio. La coagulopatía, acidosis metabólica y SRIS estuvieron asociadas a la mortalidad. Se observó una proporción de 72,50% y 3,33% de RTS < 6 en los pacientes politraumatizados que fallecieron y sobrevivieron (p = 0,001); se obtuvieron valores de sensibilidad: 73% IC 95% (59% - 86%), especificidad: 97% IC 95% (92% - 100%), valor predictivo positivo: 94% IC 95% (85% - 100%) y valor predictivo negativo: 84% IC 95% (75% - 93%). El área bajo la curva fue del 96,50% en la predicción de mortalidad por el RTS en pacientes con politraumatismo. Conclusión: El score de trauma revisado es un buen predictor de mortalidad en politraumatizados.

Objective: To determine whether the revised trauma score is a predictor of in-hospital mortality in polytrauma patients treated at Hospital Belén de Trujillo. Material and methods: An observational, analytical, retrospective, cross-sectional study of diagnostic tests was conducted, identifying patients who were admitted for polytrauma and were hospitalized in the Department of General Surgery during the period from January 2017 to December 2021; mortality was assessed in a sample of 100 patients. Results: Mean age was 47.18 ± 20.40 vs 41.13 ± 18.37 in those who died and survived; 55% and 63.33% of the deceased and survivors were male in the study groups. Coagulopathy, metabolic acidosis and SIRS were associated with mortality. A proportion of 72.50% and 3.33% STR < 6 was observed in polytrauma patients who died and survived (p = 0.001); sensitivity: 73% CI 95% (59% - 86%), specificity: 97% CI 95% (92% - 100%), positive predictive value: 94% CI 95% (85% - 100%) and negative predictive value: 84% CI 95% (75% - 93%). The area under the curve was 96.50% in predicting mortality by RTS in polytrauma patients. Conclusion: The revised trauma score is a good predictor of mortality in polytrauma patients.

Time to -30°C as a predictor of acute success during cryoablation in patients with atrial fibrillation.

BACKGROUND: Freezing rate of second-generation cryoballoon (CB) is a biophysical parameter that could assist pulmonary vein isolation. The aim of this study is to assess freezing rate (time to reach -30°C ([TT-30C]) as an early predictor of acute pulmonary vein isolation using the CB. METHODS: Biophysical data from CB freeze applications within a multicenter, nation-wide CB ablation registry were gathered. Successful application (SA), was defined as achieving durable intraprocedural vein isolation. And SA with time to isolation under 60 s (SA-TTI<60) as achieving durable vein isolation in under 60 s. Logistic regressions were performed and predictive models were built for the data set. RESULTS: 12,488 CB applications from 1,733 atrial fibrillation (AF) ablation procedures were included within 27 centers from a Spanish CB AF ablation registry. SA was achieved in 6,349 of 9,178 (69.2%) total freeze applications, and SA-TTI<60 was obtained in 2,673 of 4,784 (55.9%) freezes where electrogram monitoring was present. TT-30C was shorter in the SA group (33.4 ± 9.2 vs 39.3 ± 12.1 s; p < 0.001) and SA-TTI<60 group (31.8 ± 7.6 vs. 38.5 ± 11.5 s; p < 0.001). Also, a 10 s increase in TT-30C was associated with a 41% reduction in the odds for an SA (odds ratio [OR] 0.59; 95% confidence interval [CI] 0.56-0.63) and a 57% reduction in the odds for achieving SA-TTI<60 (OR 0.43; 95% CI 0.39-0.49), when corrected for electrogram visualization, vein position, and application order. CONCLUSIONS: Time to reach -30°C is an early predictor of the quality of a CB application and can be used to guide the ablation procedure even in the absence of electrogram monitoring.

The first year of COVID-19 vaccine roll-out in Africa: challenges and lessons learned.

Introduction: in the first year following the introduction of COVID-19 vaccines, only 6.8% of the total population in the 47 countries in the WHO African Region have received full vaccination. In an emergency context, the intra-action review helps countries to assess their progress and document what has worked and not worked. Methods: we reviewed and identified the key lessons and challenges documented in the reports from intra-action review of COVID vaccine roll out in 22 African countries. Results: all countries documented high level political commitment, but a serious shortage of COVID-19 vaccines and funding. Seven countries identified gaps in microplanning because of lack of funding or due to the unpredictability in the type and volume of vaccine supplies. The shortage of operational funding also affected training of health workers and hampered the expansion of service delivery. The countries implemented multi-channel communications and social mobilisation activities, alongside social media engagement and social listening. However, country capacity was limited in terms of timely responding to infodemics. Hesitancy among health workers and the general population was a challenge in most of the countries. Conclusion: countries have gained valuable experiences exploring various COVID-19 vaccination delivery models, including implementing the integration of COVID-19 vaccination within routine health care programs. There is a need to regularly monitor or do studies measuring public perceptions towards COVID-19 vaccination in order to drive the demand generation efforts, as well as use evidence in addressing hesitancy.

Financial impact of the hospital pharmacy's participation in clinical trials.

OBJECTIVES: To estimate the cost of the hospital pharmacy's participation in clinical trials (CTs) and to compare it to the amount received in compensation from sponsors.To analyse the financial impact of CTs that end without recruiting any patients and without any financial compensation from promoters. METHODS: This retrospective observational study analysed data from 5 years (2014-2018) at a tertiary university hospital.We established an allocation formula taking into account direct costs related to the pharmacy department's CT area's activity (reception, safekeeping, preparation, devolution, and destruction of medication, as well as patient monitoring) and indirect costs (facilities, resources, support staff). We calculated the costs to the department and the compensation received both overall and based on the type of promoter, clinical department involved in the trial, and the number of patients included. RESULTS: We included 134 trials. Costs added up to €207 372.95 and the compensation to €149 128.93 (€58 244.02 loss for the department). Trials ending without recruiting patients (33.6%) and without compensation accounted for 57.45% of the deficit. The mean cost of trials ending without recruiting patients was €875. We plan to charge a reimbursable setup fee for opening CTs to safeguard against these losses (€875 for trials in all departments except oncology; €1100 for oncology because 38% of their trials end without recruiting patients) and to compensate for the costs incurred in participating in trials for cooperative groups without financial compensation (20%). CONCLUSIONS: Billing sponsors based on costs incurred for each trial would be a fairer system than the current approach based on the number of patients included. Establishing an initial fee would make up for losses from trials that fail to recruit any patients.

Paediatric viral myocarditis successfully treated with interferon beta-1b and corticoids.

WHAT IS KNOWN AND OBJECTIVE: In paediatrics, evidence regarding the treatment of viral myocarditis using interferon beta-1B is restricted to four children older than two years and there are no reported cases of infants. The objective was to describe the efficacy and safety of interferon beta-1B in two infants under one year of age with viral myocarditis. CASE SUMMARY: Two infants were admitted to the hospital presenting with respiratory symptoms. Echocardiogram showed myocardial damage. Parvovirus-B19 was detected using a PCR assay, and treatment with interferon beta-1B was initiated. Six months later, the cardiac function had recovered in both cases. WHAT IS NEW AND CONCLUSION: This is the first published series of cases of infants less than 1 year of age with viral myocarditis treated with interferon beta-1B.

[Usefulness of laser Holmium Lumenis Pulse 120 H® in the treatment of renal lithiasis through RIRS: Preliminary experience.] / Utilidad del láser Holmium Lumenis Pulse 120 H® en el tratamiento de las litiasis renales mediante RIRS: experiencia preliminar.

INTRODUCTION: The Holmium laser is the most used energy source in flexible ureterrenoscopy (URSf). The Lumenis Pulse 120H® laser has a higher system energy, a higher energy per pulse and a higher repetition frequency in relation to other types of lasers, which offers advantages in the treatment of lithiasis. OBJECTIVE: To analyze the results that we have obtained with the use of the Lumenis Pulse120H® laser in patients treated by intrarenal retrograde surgery (RIRS). As secondary objectives there are: the study of the demographic variables of the patients, the characteristics of the stones and the complications associated with the procedure. MATERIAL AND METHODS: An observational, retrospective study of the first 26 patients treated by RIRS and Lumenis Pulse 120H® laser has been performed in our Service between August 2018 and February 2019. The size of the lithiasis was measured on the simple radiography and the CT, in addition, the volume of the lithiasis was calculated. For the realization of RIRS, 8.5Fr digital flexible ureterorenoscope (Olympus®) and the Holmium Lumenis 120H® laser with 200 micron laser fibers from Lumenis® were used. Statistical analysis was performed with the SPSSv21 system. RESULTS: A total of 26 patients with renal lithiasis have been analyzed. The median age was 55.15 years (40.67-67.05). 57.7% of the patients had prior surgical treatment of lithiasis. Thirteen patients presented the litiasis in the renal pelvis, ten in the Upper Calicial Group (GCS), fifteen in the Middle Calicial Group (GCM) and eighteen in the Lower Calicial Group (GCI). The median of the lithiasic volume was 1826.41 mm3. Our overall success rate was 80.8% (100% success in lithiasis less than 2 cm and 85.7% in lithiasis between 2-3 cm). Five patients presented complications, of which 4 were ClavienII and 1 Clavien IIIb. No significant results were found between the lithiasic size and the presence of complications (p = 0.128). CONCLUSIONS: The use of the Lumenis Pulse 120H®laser is an useful tool for the treatment of kidney stones by RIRS, due to his efficiency in the fragmentation and dusting, taking into account that very large lithiasic masses require, in a high percentage of cases, more than one treatment session.

INTRODUCCIÓN: El láser de Holmium es la fuente de energía más utilizada en la ureterrenoscopia flexible (URSf). El láser Lumenis Pulse 120H® tiene una mayor energía del sistema, una mayor energía por pulso y una frecuencia de repetición más elevada en relación a otros tipos de láser, lo que ofrece ventajas en el tratamiento de las litiasis. OBJETIVO: Analizar los resultados que hemos obtenido con la utilización del láser Lumenis Pulse120H® en pacientes tratados mediante RIRS. Como objetivos secundarios se encuentra el estudio de las variables demográficas de los pacientes, de las características del cálculo y de las complicaciones asociadas al procedimiento.MATERIAL Y MÉTODOS: Se ha realizado un estudio observacional, retrospectivo, de los primeros 26 pacientes tratados mediante RIRS y láser Lumenis Pulse 120H® en nuestro Servicio entre agosto 2018 y febrero 2019. El tamaño de la litiasis fue medido en la radiografía simple y el TC (tomografía computarizada) y, aparte, se calculó el volumen de la litiasis. El análisis estadístico se realizó con el sistema SPSSv21. RESULTADOS: Se han analizado un total de 26 pacientes con litiasis renales. Un 57,7% de los pacientes tenían tratamiento quirúrgico previo de litiasis. Presentaban litiasis en la pelvis renal 13 pacientes, en Grupo Calicial Superior (GCS) 10, en Grupo Calicial Medio (GCM) 15 y en Grupo Calicial Inferior (GCI) 18. La mediana del volumen litiásico fue de 1.826,41 mm3. Nuestra tasa global de éxito fue del 80,8% (100% éxito en litiasis menores de 2 cm y 85,7% en litiasis entre 2-3cm). Cinco pacientes presentaron complicaciones, de ellos 4 fueron Clavien II y 1 Clavien IIIb. No se hallaron resultados significativos al relacionar el tamaño litiásico con las complicaciones (p=0,128). CONCLUSIONES: La utilización del láser Lumenis Pulse120H® es una herramienta útil y segura para el tratamiento de los cálculos renales mediante RIRS, debido a la eficacia en la fragmentación y pulverización de los mismos, teniendo en cuenta que las masas litiásicas muy grandes requieren, en un alto porcentaje de casos, más de una sesión de tratamiento.

Differences in classroom motivational climate: causes, effects and implications for teacher education. A multilevel study / Diferencias en el clima motivacional en el aula: causas, efectos e implicaciones para la formación docente. Un estudio multinivel

Research on classroom motivational climate (CMC) has shown significant differences between classrooms in CMC. However, it is not known whether teachers' motivational knowledge, and goals and expectancies related to their students contribute to such differences, and consequently, on the effects of CMC on students. For answering this question, a multilevel model of the relationships among a) teachers' knowledge and motivational characteristics, b) students' goals and expectancies (SGE), c) perceived CMC, and d) students' attribution of perceived motivational improvement to teachers (APMIT) was tested using structural equation methods. A total of 2.223 Secondary and High-School students and their 95 teachers participated in the study. Results showed that teachers' motivational quality (TMQ) has a significant indirect effect on differences between classrooms in CMC, and on the students' attribution of perceived improvement in motivational variables to teachers, but also that teachers' characteristics differ in their contribution to TMQ, and so, to CMC

La investigación sobre el clima motivacional en el aula (CMC) ha mostrado diferencias significativas entre las aulas en CMC. Sin embargo, no se sabe si el conocimiento motivacional de los docentes y las metas y expectativas relacionadas con sus alumnos contribuyen a tales diferencias y, en consecuencia, a los efectos de la CMC en los alumnos. Para responder a esta pregunta, un modelo multinivel de las relaciones entre a) el conocimiento y las características motivacionales de los profesores, b) las metas y expectativas de los estudiantes (SGE), c) la percepción de CMC, y d) la atribución de los estudiantes de la mejora motivacional percibida a los maestros (APMIT) se probó utilizando métodos de ecuaciones estructurales. Un total de 2.223 estudiantes de secundaria y preparatoria y sus 95 profesores participaron en el estudio

Development and validation of the School Climate Questionnaire for Secondary and High School Teachers (SCQ-SHST) / Desarrollo y validación del Cuestionario de Clima Escolar para Profesores de Secundaria y Bachillerato (CES-PSB)

The present study focuses on the development and initial validation of a measure of school climate based on teachers' perceptions. The measure was developed to integrate those aspects of the school climate highlighted in the existing literature and that proved relevant for teachers' efficacy, including the school goal structure. Exploratory and confirmatory factor analyses were conducted on a sample of 581 high school teachers. Results showed that a seven-correlated factor structure better represented the data, in comparison with a second-order model and a bifactor model. Structural equation modeling techniques provided evidence of the concurrent validity through correlations with a criterion measure of teacher job satisfaction. School goal structure proved to be an important aspect of school climate substantially related to other school climate factors such as school management quality and relationships among teachers. These findings provided some empirical support for the use of the questionnaire in schools, especially for those interested in articulating interventions aimed at improving the learning environment through the seven school climate dimensions addressed

El presente estudio se centra en el desarrollo y validación inicial de una medida del clima escolar basada en las percepciones de los profesores. La medida fue desarrollada para integrar aquellos aspectos del clima escolar destacados en la literatura existente, incluyendo la estructura de metas escolar. Se realizaron análisis factoriales exploratorios y confirmatorios con una muestra de 581 profesores de secundaria y bachillerato. El uso de modelos de ecuaciones estructurales proporcionó evidencia sobre la validez concurrente a través de correlaciones con una medida criterio sobre la satisfacción laboral de los profesores. La estructura de metas escolar demostró ser un aspecto relevante para definir el clima escolar relacionándose sustancialmente con otros aspectos del mismo tales como la calidad del liderazgo o el apoyo entre profesores. Estos resultados proporcionaron evidencias empíricas a favor del uso del cuestionario propuesto entre las escuelas, especialmente en aquellas interesadas en particular intervenciones encaminadas a mejorar el entorno de aprendizaje a través de las siete dimensiones del clima escolar abordadas

Development and validation of a sexual relations satisfaction scale in patients with breast cancer - "SEXSAT-Q".

PURPOSE: Because the currently available questionnaires to evaluate sexual changes on breast cancer women only address the sexual sphere with a few questions our purpose was to develop a questionnaire that assesses changes in sexual dysfunction and satisfaction in women treated for breast cancer. METHODS: A sample was selected of women aged between 18 and 65 who had had surgery for breast cancer, completed neoadjuvant/adjuvant chemotherapy treatment and could be receiving adjuvant hormonal treatment, with an active sex life at least 3 months before starting treatment. Metastatic disease was excluded. A questionnaire structured in 4 dimensions was developed. The MOS SF-12 and QLQ-BR23 questionnaires were also provided. The following metric properties were evaluated: item analysis; internal consistency; temporal stability; construct validity; concurrent, convergent and divergent validity; and feasibility. RESULTS: Three samples were recruited: a pilot sample of 20; a reduction sample of 152; and a validation sample of 148. The presence of 6 dimensions was confirmed: 1) Loss of sex drive; 2) worsening of body image; 3) psychological coping; 4) discomfort during intercourse; 5) satisfaction with sexual relations; and 6) satisfaction with breast reconstruction. Good goodness-of-fit statistics were obtained (χ2/df = 1.5, GFI = 0.9, AGFI = 0.84, CFI = 0.959, RMSEA = 0.062). Reliability was good (α = 0.855), as was test-retest stability (r = 0.838). The correlation with the convergent questionnaires proved to be higher than that obtained with generic measurements. CONCLUSIONS: We were able to develop a short questionnaire (17 items) capable of measuring sexual satisfaction in women with breast cancer with good metric properties.

Complicaciones agudas de la Diabetes mellitus, visión práctica para el médico en urgencias: Revisión de tema / Acute complications of diabetes mellitus, practical vision for the emergency physician: Review

La Diabetes Mellitus (DM) representa una de las Enfermedades Crónicas No Transmisibles (ECNT) más prevalentes del mundo, cuyas complicaciones agudas o emergencias hiperglucémicas más importantes, en el escenario de la medicina de urgencias, son la Cetoacidosis Diabética (CAD), el Estado Hiperglucémico Hiperosmolar (EHH) y la Hipoglucemia, todas ellas asociadas a un control inadecuado o insuficiente de la enfermedad. Con el objetivo de mejorar eficazmente la condición clínica de los pacientes que presentan algún tipo de emergencia hiperglucémica, los médicos del servicio de urgencias deben tener claridad en diversos aspectos clave relacionados con la fisiopatología y el abordaje apropiado para cada situación. En este artículo se reúne la información más actualizada respecto a la definición, epidemiología, etiopatogenia, manifestaciones clínicas, diagnóstico, tratamiento y prevención, de las tres complicaciones agudas de la DM, a fin de ofrecer al clínico una guía práctica para el abordaje y manejo adecuado de los pacientes diabéticos en el contexto de las emergencias hiperglucémicas.

Diabetes Mellitus (DM) represents one of the most prevalent Chronic Noncommunicable Diseases (NCDs) in the world, which acute complications or major hyperglycemic emergencies, in the scenario of emergency medicine, are Diabetic Ketoacidosis (DKA), the State Hyperosmolar hyperglycemic (EHH) and Hypoglycaemia, all associated with inadequate or insufficient control of the disease. In order to effectively improve the clinical condition of patients presenting with some type of hyperglycaemic emergency, emergency department physicians should be clear about various key aspects related to the pathophysiology and the appropriate approach for each situation. This article gathers the most up-to-date information regarding the definition, epidemiology, etiopathogenesis, clinical manifestations, diagnosis, treatment and prevention of the three acute complications of DM mentioned above, in order to offer the clinician a practical guide for the approach and proper management of diabetic patients in the context of hyperglycemic emergencies.

[Profiles of intestinal polyparasitism in a community of the Colombian Amazon region].

INTRODUCTION: Intestinal parasite infections and polyparasitism are highly prevalent in the most vulnerable populations of developing countries due to environmental, biological and social determinants common in the transmission of parasites. Children between 1 and 15 years of age are the most affected population. OBJECTIVE: To describe the prevalence and profiles of intestinal polyparasitism in 1 to 15 year-old children from native communities in the Colombian Amazon region. MATERIALS AND METHODS: We used a non-probability sampling of 300 children between 1 and 15 years of age from several rural settlements and the main urban area of Puerto Nariño, Amazonas, Colombia, who participated voluntarily in the study. We obtained fecal samples that were analyzed by the direct method (0.85% saline solution-lugol) and the Kato-Katz technique. The most prevalent polyparasitism profiles were identified using Cohen's kappa coefficient with a 95% confidence interval. RESULTS: The prevalence of polyparasitism, defined as the presence of at least two intestinal pathogenic parasites, was 84% (95 % CI: 79.35-87.96). Polyparasitism by two or three of the following parasites: Ascaris lumbricoides, Trichuris trichiura, Blastocystis sp., Ancylostoma duodenale and Necator americanus from the Ancylostomatidae family, and Entamoeba histolytica, E. dispar and E. moshkovskii of the Entamoeba complex, had the highest prevalence. CONCLUSION: Several intestinal polyparasitism profiles were found, although in most cases fewer than six parasites were involved. Better prevalence estimations and identification of determinant factors will allow to priorize and direct resources to control these infections.

Determinantes biológicos de mortalidad neonatal, en una población de mujeres adolescentes y adultas de un hospital en Colombia / Biological determinants of neonatal mortality, in a population of adolescent and adult women of a hospital in Colombia

INTRODUCTION. La muerte neonatal está asociada a determinantes maternos, obstétricos, fetales, neonatales y los cuidados de la salud. OBJETIVO Establecer los determinantes asociados a mortalidad neonatal en una unidad de cuidados intensivos de Colombia. Métodos. Estudio de casos y controles anidado en una cohorte, donde se incluyeron 5567 neonatos vivos, de los cuales fallecieron 125. Con Stata 11.0® se construyeron las estadísticas descriptivas y mediante odds ratio (intervalo de confianza 95%) se establecieron las asociaciones. La regresión logística fue empleada en el análisis multivariado. Se consideró un valor de p<0,05 como significativo. RESULTADOS. La mortalidad se presentó en 2,25% de los neonatos, ocurriendo 76,80% de las muertes entre 0-7 días. Los determinantes maternos y obstétricos asociados de manera independiente a mortalidad neonatal incluyeron número de visitas en el control prenatal menor a 6, trabajo de parto prematuro espontáneo, sangrados del tercer trimestre e hipertensión arterial crónica. Entre los determinantes neonatales, la necesidad de reanimación cardiorrespiratoria, prematuridad o bajo peso al nacer, infecciones bacterianas graves, enfermedad de membrana hialina, hipertensión pulmonar, malformaciones congénitas y anomalías cromosómicas y cardiomiopatía hipertrófica, se asociaron independientemente a mortalidad neonatal. Para las complicaciones y eventos adversos hubo asociación independiente y estadísticamente significativa para infecciones asociadas a la atención en salud, hemorragia intraventricular grados III y IV de Papille y hemorragia pulmonar. CONCLUSIONES. La mortalidad neonatal obedeces a determinantes maternos, obstétricos y feto-neonatales, por lo cual el mejoramiento de los cuidados de estos, reduciría la mortalidad neonatal.

INTRODUCTION. Neonatal death is associated with maternal, obstetric, fetal, neonatal, and health determinants. Objective. To establish the determinants associated with neonatal mortality in a Colombian intensive care unit. METHODS. Case-control study nested in a cohort, where 5567 live infants were included, of which 125 died. Stata 11.0® descriptive statistics were constructed and associations were established using odds ratio (95% confidence interval). Logistic regression was used in the multivariate analysis. A value of p <0.05 was considered significant. RESULTS. Mortality occurred in 2.25% of neonates, with 76.80% of deaths occurring between 0-7 days. Maternal and obstetric determinants independently associated with neonatal mortality included numbers of visits in prenatal control less than 6, spontaneous preterm labor, third trimester bleeding, and chronic hypertension. Among neonatal determinants, the need for cardiorespiratory resuscitation, prematurity or low birth weight, severe bacterial infections, hyaline membrane disease, pulmonary hypertension, congenital malformations and chromosomal abnormalities, and hypertrophic cardiomyopathy were independently associated with neonatal mortality. For complications and adverse events, there was an independent and statistically significant association for infections associated with health care, intravenous haemorrhage degrees III and IV of Papille, and pulmonary hemorrhage. CONCLUSIONS. Neonatal mortality is due to maternal, obstetric and fetal-neonatal determinants, so improving neonatal care will reduce neonatal mortality.

Perfiles de poliparasitismo intestinal en una comunidad de la Amazonia colombiana / Profiles of intestinal polyparasitism in a community of the Colombian Amazon region

Resumen Introducción. Las infecciones parasitarias y el poliparasitismo intestinal son muy prevalentes en las poblaciones más vulnerables de los países en desarrollo debido a la existencia de factores ambientales, biológicos y sociales determinantes en la transmisión de parásitos. La población entre uno y 15 años de edad es la más afectada por dicha situación. Objetivo. Describir las prevalencias y los perfiles del poliparasitismo intestinal en la población de uno a 15 años de edad de comunidades indígenas de la Amazonia colombiana. Materiales y métodos. Se hizo un muestreo no probabilístico de 300 niños entre uno y 15 años de edad, procedentes de varios asentamientos rurales y de la cabecera urbana de Puerto Nariño, Amazonas, quienes participaron voluntariamente en el estudio. Las muestras de materia fecal se analizaron mediante el método directo (solución salina al 0,85 % y lugol) y la técnica de Kato-Katz. Se determinaron los perfiles más prevalentes de poliparasitismo intestinal con el coeficiente kappa de Cohen y un intervalo de confianza de 95 %. Resultados. La prevalencia de poliparasitismo, definida como la presencia de, por lo menos, dos parásitos intestinales patógenos, fue de 84 % (IC95 %: 79,35-87,96). Los casos con presencia de dos o tres agentes incluyeron los parásitos Ascaris lumbricoides, Trichuris trichiura, Blastocystis sp., los ancilostomídeos Ancylostoma duodenale yNecator americanus, así como Entamoeba histolytica,E. dispar y E. moshkovskii del complejo Entamoeba, y fueron los de mayor prevalencia. Conclusión. Se encontraron varios perfiles de poliparasitismo intestinal, aunque la mayoría de los casos involucraron menos de seis especies. Una mejor estimación de la prevalencia y los factores determinantes del poliparasitismo intestinal permitirían priorizar y orientar los recursos para su control.

Abstract Introduction: Intestinal parasite infections and polyparasitism are highly prevalent in the most vulnerable populations of developing countries due to environmental, biological and social determinants common in the transmission of parasites. Children between 1 and 15 years of age are the most affected population. Objective: To describe the prevalence and profiles of intestinal polyparasitism in 1 to 15 year-old children from native communities in the Colombian Amazon region. Materials and methods: We used a non-probability sampling of 300 children between 1 and 15 years of age from several rural settlements and the main urban area of Puerto Nariño, Amazonas, Colombia, who participated voluntarily in the study. We obtained fecal samples that were analyzed by the direct method (0.85% saline solution-lugol) and the Kato-Katz technique. The most prevalent polyparasitism profiles were identified using Cohen's kappa coefficient with a 95% confidence interval. Results: The prevalence of polyparasitism, defined as the presence of at least two intestinal pathogenic parasites, was 84% (95 % CI: 79.35-87.96). Polyparasitism by two or three of the following parasites: Ascaris lumbricoides,Trichuris trichiura, Blastocystis sp., Ancylostoma duodenale and Necator americanus from the Ancylostomatidae family, and Entamoeba histolytica,E. dispar and E. moshkovskii of the Entamoeba complex, had the highest prevalence. Conclusion: Several intestinal polyparasitism profiles were found, although in most cases fewer than six parasites were involved. Better prevalence estimations and identification of determinant factors will allow to priorize and direct resources to control these infections.
