Hypoglycemic treatment of diabetic patients in the Emergency Department

Objectives: To analyze if the hypoglycemic therapy prescribed in the Emergency Department adapts to the consensus recommendations available, as well as to assess its clinical impact. Methods: A descriptive observational study, which included patients awaiting hospital admission, who were in the Observation Ward of the Emergency Department and had been previously diagnosed with diabetes mellitus, and were receiving treatment with hypoglycemic drugs at home. The management of antidiabetic treatment and its clinical impact were assessed. Results: 78 patients were included. At admission to the Emergency Department, treatment was modified for 91% of patients, and omitted for 9%. The most prescribed treatment was sliding scale insulin (68%). The treatments prescribed coincided in a 16.7% with the recommendations by the Spanish Society of Emergency Medicine. After intervention by the Pharmacist, the omission descended to 1.3%, and the adaptation to the recommendations increased to 20.5%. Comparing patients whose treatment coincided with the recommendations and those who did not, the clinical impact was respectively: mean glycemia at 24 hours: 138.3 ± 49.5 mg/dL versus 182.7 ± 97.1 mg/dL (p = 0.688); mean rescues with insulin lispro: ± 1.6 versus 1.5 ± 1.8 (p = 0.293); mean units of insulin lispro administered: 4.6 ± 12.7 IU versus 6.6 ± 11.3 IU (p = 0.155). Conclusions: We found antidiabetic prescriptions to have a low adaptation to consensus recommendations. These results are in line with other studies, showing an abuse of sliding scale regimen as single hypoglycemic treatment.

Procalcitonin Biomarker Kinetics to Predict Multiorgan Dysfunction Syndrome in Children With Sepsis and Systemic Inflammatory Response Syndrome

Background: Procalcitonin (PCT) kinetics is a good prognosis marker in infectious diseases, but few studies of children sepsis have been performed. Objectives: The aim of our study was to examine kinetics of procalcitonin, to evaluate its relationship with severity and to analyze its usefulness in the prediction of multiorgan dysfunction syndrome (MODS). Patients and Methods: Prospective observational study in an 8-bed pediatric intensive care unit of a university hospital. Sixty-two children aged 0-19 years with systemic inflammatory response syndrome or septic states. The degree of severity was evaluated according pediatric logistic organ dysfunction (PELOD) score. Blood tests to determine levels of PCT were taken if the patients had the criteria of systemic inflammatory response syndrome or sepsis. The serum to determine levels of PCT in control group has been taken from patients undergoing elective surgery. Results: Higher values of PCT were identified in patients with PELOD score 12 and more compared to those with PELOD < 12 (P = 0.016). Similarly, higher PCT values were found in patients who developed MODS in contrast to those without MODS (P = 0.011). According to ROC analysis cut-off value of 4.05 ng/mL was found to best discriminate patients with PELOD < 12 and PELOD ≥ 12 with AUC = 0.675 (P = 0.035). Effect of procalcitonin levels on mortality was not demonstrated. Conclusions: Levels of procalcitonin from day 1 to day 5 are related to the severity and multiorgan dysfunction syndrome in children.

Initial approach to irst-time seizures in pediatrics

Objective: Prove that conducting complementary studies at laboratories and imaging studies are unnecessary in irst-time unprovoked seizures, since there is no change in the evolution and prognosis of the disease, as well as the study of our population, the incidence rate and the proportion of our patients that have been studied and given maintenance treatment, so it can be determined whether or not our population should follow the suggestions of the American Academy of Pediatrics and the Spanish Pediatric Association. Methods: An observational study, including patients diagnosed with irst-time unprovoked seizures. They were followed up on by the emergency department and information was collected from their clinical history and compared with the results of the different studies between patients that suffered just one seizure and the ones that had recurrent seizures. Results: Thirty one patients were included, 14 males and 17 females. The average age was 5.5 years old. The 100% of patients were studied, and the groups were compared. The signiicant study was the electroencephalogram (EEG) with a p=0.02 (signiicance p<0.05), incidence of 41%. Conclusions: The study and diagnosis of irst-time unprovoked seizures is based on clinical manifestations. The EEG is important in the study and classiication of unprovoked seizures. Our population has an incidence and recurrence rate similar to that in the bibliography, and for that reason, this study suggests that the diagnostic and therapeutic guidelines of the American Academy of Pediatrics and the Spanish Pediatric Association should be followed.

Factores relacionados a sépsis neonatal. Unidad de Neonatología Clínica Humanitaria-Fundación Pablo Jaramillo

Se realizó un estudio observacional en recién nacidos sépticos ocurridos en la Unidad de Neonatología de la Fundación Humanitaria Pablo Jaramillo, durante el período de enero de 2009 a diciembre de 2011, con el objetivo de analizar la incidencia de antecedentes maternos y parámetros propios del recién nacido como posibles factores de riesgo para la sepsis, los parámetros de laboratorio que contribuyen a diagnosticar procesos infecciosos en el recién nacido y el desenlace que tuvieron los mismos. Durante este tiempo ingresaron 164 casos con riesgo de sepsis, sospecha de sepsis y sepsis bacteriana (42.62 /1000 nacidos vivos) y la mortalidad fue del 3.04%. Predominó la sepsis de inicio precoz sobre la tardía. Los principales antecedentes maternos fueron la ruptura prematura de membranas seguido de la infección de vías urinarias. En cuanto a los factores del recién nacido prevaleció el sexo masculino, prematurez y de bajo peso al nacer

Serum Hsp70 Antigen: Early Diagnosis Marker in Perinatal Asphyxia

Background: Perinatal asphyxia is an important cause of mortality and permanent neurological and developmental deficit. Early and accurate diagnosis would help to establish the likely prognosis and may also help in determining the most appropriate treatment. Studies in experimental animal models suggest that a protein called Hsp70 may be a good and potentially useful marker of cellular stress that may be clinically useful in determining the presence of neonatal asphyxia. Objectives: Regarding the importance of early and accurate diagnosis of asphyxia, we conducted this study, which is the first investigation of the comparison of the serum Hsp70 antigen level between asphyxiated and healthy infants. Patients and Methods: In this observational study, the serum concentrations of Hsp70 antigen were compared between neonates suffering from perinatal asphyxia (n = 50) and normal neonates (n = 51). The inclusion criteria for the cases were neonates who had reached term and had at least two clinical criteria of asphyxia. Exclusion criteria were babies with gestational age < 37 weeks, infants with congenital abnormalities or positive blood culture. Exclusion criteria in this group were the requirement to hospital stay during first week of the life or babies whose mothers had difficulties during pregnancy or delivery. Term neonates without major anomalies who had asphyxia during delivery were enrolled in the first six hours after delivery, and control group consisted of healthy term neonates without problems and normal delivery process in the first week of life. The cord blood was taken during labor to measure Hsp70 antigen level by using an in-house ELISA (The enzyme-linked immunosorbent assay). Results: The median values of serum anti Hsp70 titers were significantly higher in asphyxiated neonates compared with non-asphyxiated neonates (0.36 [0.04 - 1.14] vs 0.24 [0.01 - 0.63]). At cutoff point = 0.3125 ng/mL, sensitivity was 58% and specificity 76% based on ROC curve. Conclusions: A significant difference between the serum concentrations of Hsp70 of the control and patient group was observed in this study. It is inferred serum concentrations of Hsp70 antigen may be a useful marker for the early diagnosis of that prenatal hypoxia.

Prevalence of diabetic retinopathy in type II diabetic patients in a health facility in Karachi, Pakistan

Purpose: To study the prevalence of diabetic retinopathy in known diabetic patients attending the diabetes outpatient department (OPD) of Sind Government Hospital (SGH), New Karachi Township (NKT), Pakistan. Methods: A cross-sectional observational study was carried out at the diabetic OPD of SGH, NKT over the period of 17 months from March 2013 to August 2014. The selected patients were interviewed based on a questionnaire; laboratory investigations were performed and examination of the eye was conducted by a specialist ophthalmologist. One hundred and fifty four (154) subjects out of 305 patients contacted fully completed the study. Stratification of the data on gender basis was done, after which one-way ANOVA, χ2 test of correlation, binary logistic regression and relative risk analyses were carried out using SPSS-20. Results: It was found that 66 % men of normal weight (χ2 = 4.667, p < 0.05) and 60.7 % overweight women (χ2 = 5.143, p < 0.05) were more likely to present with diabetic retinopathy (DR). Prevalence of DR in this target population was 42.86 % (N = 66). Background DR (56 %) and maculopathy (23 %) were more prevalent than advanced conditions of the disease. There was no gender-based preponderance for the presentation of DR (χ2 = 0.663; p > 0.05), nor was this seen in different ethnic groups. Conclusion: DR is prevalent in the target population and, therefore, emphasis should be on the education of the local population of New Karachi Township on how to attain euglycemic state with regular medication, diet and exercise to avoid development and progress of DR.

Diez primeras causas de morbilidad en emergencia del Hospital Homero Castanier Crespo en el periodo de octubre a diciembre del 2014. Azogues-Ecuador

Antecedentes: Es preciso mencionar que en México en el 2005 estadísticas muestran que las principales causas de morbilidad en su servicio de emergencias las constituyen: Infecciones respiratorias agudas (19,4%), los traumatismos y envenenamientos (18,8%) y las enfermedades diarreicas (8%). (14). En Perú la principal causa de morbilidad se debió a traumatismos (12% del total), seguido en segundo lugar de asma (10%) y en tercer lugar por anormalidades y complicaciones del embarazo, parto o puerperio (8% del total). (5) Objetivo: Determinar las 10 primeras causas de morbilidad en emergencia del Hospital Homero Castanier Crespo en el período de octubre a diciembre 2014. Materiales y métodos: Se realizó un estudio observacional indirecto, mediante el registro de emergencia del total de pacientes que han acudido a emergencia en el Hospital Homero Castanier Crespo en período comprendido entre octubre – noviembre del 2014. El instrumento utilizado fue el formulario de recolección de datos (ver anexo 2). Resultados: la principal causa de morbilidad en la emergencia del Hospital Homero Castenier Crespo constituyen las enfermedades infecciosas: Enfermedades infecciosas intestinales, Amigdalitis aguda con un 10.86%. Gran parte de las morbilidades atendidas en la emergencia 20.85%, no son emergencias reales. En grupos edad pediátrica y adultos mayores, la principal causa fueron las Enfermedades infecciosas intestinales 14.52%, 6.96% respectivamente, que en este grupo si constituyen un verdadera emergencia. En ginecobstetricia: Falso trabajo de parto a las 37 y más semanas completas de gestación Conclusión: el estudio muestra las principales causas de morbilidad en el Hospital Homero Cartanier Crespo, revela una saturación del sistema por la cantidad de no emergencias que se atienden. Probablemente por la falta de un triage adecuado

Complications associated with malnutrition in elective surgical patients in a Malaysian setting

Purpose: To identify the level of malnutrition and complications observed in Malaysia. Methods: A prospective, observational study was conducted with the objectives of identifying the degree of malnutrition, complications and the need for nutritional support in elective surgical patients. Collection of data was performed in local tertiary hospitals using a Patient Generated Subjective Global Assessment (PG - SGA) nutritional screening tool and medical records. Results: A total of 50 patients electively admitted for surgery were included. The results demonstrated that there was a significant increase in malnourished patients post-surgery compared to pre-surgery (p = 0.0001). Most interesting was the significant number of complications observed post-surgery compared to pre-surgery (p = 0.035) which was associated to the poor level of nutrition. The most common type of complications noted post-surgery were nosocomial infection, wound infection and readmission. Conclusion: Malnutrition is prevalent pre- and post-operatively in Malaysia. Therefore, focus on the outcome of these malnourished patients should be performed to reduce complications associated with poor nutrition.

Older patients are immunocompromised by cytokine depletion and loss of innate immune function after hip fracture surgery

PURPOSE/INTRODUCTION: We have examined the immune status of elderly patients who underwent surgery for a hip fracture, an injury associated with poor postoperative outcomes, to identify specific immune defects. METHODS: In a cohort observational study, 16 patients undergoing surgery for hip fractures had immune function evaluation prior to surgery, and then at 3 and 7 days postoperatively, using flow cytometry for phenotype and for monocyte and granulocyte phagocytic function and respiratory burst. Serum samples were stored and batch analyzed using a human cytokine 25-plex panel. RESULTS: We report significant loss of innate immune function, related specifically to reduced granulocyte numbers by day 7 (P < .0001, flow cytometry; P < .05 white blood cells), and although granulocyte ability to take up opsonized Escherichia coli was increased (P < .05), the ability of those cells to generate a respiratory burst was reduced at days 3 and 7 (P < .05). Monocyte respiratory burst was also significantly reduced (P < .05). Serum cytokine levels indicated very poor T-cell function. CONCLUSION: We have demonstrated that the antimicrobial immune response is profoundly reduced after surgery in elderly patients with hip fractures. The effect was sustained up to 7 days postoperatively, identifying these patients as particularly vulnerable to bacterial infections.

Incidence of complications in men undergoing transurethral resection of the prostate

Objectives: To examine the link between medication use and the risk of bleeding complications following transurethral resection of the prostate from the second postoperative day until hospital discharge. Method: Using a retrospective observational study design, the medical records of all patients who underwent transurethral resection of the prostate over a 24-month period were examined. Comprehensive data regarding patients' medication history, comorbidities and complications that occurred either during or after surgery were collected from medical records. Inferential statistical analysis was used to examine associations between demographic and medication variables and the risk of complications. Results: Complications arising after surgery occurred in 48/135 (36%) of patients. The most common complications postoperatively were hematuria, occurring in 41/48 (85%) and hematuria with clot retention, occurring in 24/48 (50%) of patients who suffered complications. There was a significant association between the number of medications prescribed and postoperative complications; for hematuria, χ ² (12)=21.50, p =0.04; and for hematuria with clot retention χ ² (12)=24.97, p =0.015. Conclusions: Demographic data relating to patients' age, comorbid state and the number of standard medications prescribed is associated with an increase in macroscopic hematuria and macroscopic hematuria with clot retention after transurethral resection of the prostate. These findings emphasize the importance of nursing practice in both preoperative and postoperative care of patients undergoing surgery. Nurses need to be very vigilant in assessing patients at risk of increased bleeding from a transurethral resection of the prostate by examining their medication regimen.

Association between maternal education and objectively measured physical activity and sedentary time in adolescents

BACKGROUND: Investigating socioeconomic variation in physical activity (PA) and sedentary time is important as it may represent a pathway by which socioeconomic position (SEP) leads to ill health. Findings on the association between children's SEP and objectively assessed PA and/or sedentary time are mixed, and few studies have included international samples.

OBJECTIVE: Examine the associations between maternal education and adolescent's objectively assessed PA and sedentary time.

METHODS: This is an observational study of 12 770 adolescents (10-18 years) pooled from 10 studies from Europe, Australia, Brazil and the USA. Original PA data were collected between 1997 and 2009. The associations between maternal education and accelerometer variables were examined using robust multivariable regression, adjusted for a priori confounders (ie, body mass index, monitor wear time, season, age and sex) and regression coefficients combined across studies using random effects meta-analyses. Analyses were conducted in March 2014.

RESULTS: Adolescents of university educated mothers spent more time sedentary (9.5 min/day, p=0.005) and less time in light activity (10 min/day, p<0.001) compared with adolescents of high school educated mothers. Pooled analysis across two studies from Brazil and Portugal (analysed separately because of the different coding of maternal education) showed that children of higher educated mothers (tertiary vs primary/secondary) spent less time in moderate to vigorous PA (MVPA) (6.6 min/day, p=0.001) and in light PA (39.2 min/day: p<0.001), and more time sedentary (45.9 min/day, p<0.001).

CONCLUSIONS: Across a number of international samples, adolescents of mothers with lower education may not be at a disadvantage in terms of overall objectively measured PA.

Activities patients and nurses undertake to promote patient participation

PURPOSE: To describe and understand activities patients and nurses undertake to enact patient participation in nursing care. DESIGN: This observational study was conducted on two medical units at a public hospital in Australia. Twenty-eight nurse-patient dyads were observed for at least 4 hr. Data were collected from November 2013 to February 2014. METHODS: Field notes were collected and were analyzed both inductively and deductively. FINDINGS: Nurse-patient interactions promoted patient participation through dialogue and knowledge sharing. Less evident was patient involvement in planning or self-care. Nurses exerted control over patient care, which influenced the extent of patient participation. CONCLUSIONS: Patient participation appears to be difficult to enact. Nurses' controlling approach, influenced by organizational issues, was in conflict with a patient-centered approach to care. Nurse-patient communication is one aspect of patient-centered care enacted more frequently. CLINICAL RELEVANCE: Nurses may benefit from strategies at the individual and organizational level to enhance their patient-centered practices. Fostering nurses' communication may enhance patient-centered practices in hospitals.

Systematic review of sedentary behavior and cognitive development in early childhood

OBJECTIVE: To comprehensively review observational and experimental studies examining the relationship between sedentary behavior and cognitive development during early childhood (birth to 5years). METHOD: Electronic databases were searched in July, 2014 and no limits were imposed on the search. Included studies had to be peer-reviewed, published, and meet the a priori determined population (apparently healthy children aged birth to 5years), intervention (duration, types, and patterns of sedentary behavior), comparator (various durations, types, or patterns of sedentary behavior), and outcome (cognitive development) study criteria. Data extraction occurred in October and November 2014 and study quality and risk of bias were assessed in December 2014. RESULTS: A total of 37 studies, representing 14,487 participants from nine different countries were included. Thirty-one studies used observational study designs and six studies used experimental study designs. Across study designs, increased or higher screen time (most commonly assessed as television viewing (TV)), reading, child-specific TV content, and adult-specific TV content had detrimental (negative) associations with cognitive development outcomes for 38%, 0%, 8%, and 25% of associations reported, respectively, and beneficial (positive) associations with cognitive development outcomes for 6%, 60%, 13%, and 3% of associations reported, respectively. Ten studies were moderate quality and 27 studies were weak quality. CONCLUSIONS: The type of sedentary behavior, such as TV versus reading, may have different impacts on cognitive development in early childhood. Future research with reliable and valid tools and adequate sample sizes that examine multiple cognitive domains (e.g., language, spatial cognition, executive function, memory) are needed.

L'activité tonique diaphragmatique chez les enfants avec et sans support respiratoire

Introduction : Les nourrissons, vu la grande compliance de leur cage thoracique, doivent maintenir activement leur volume pulmonaire de fin d’expiration (VPFE). Ceci se fait par interruption précoce de l’expiration, et par le freinage expiratoire au niveau laryngé et par la persistance de la contraction des muscles inspiratoires. Chez les nourrissons ventilés mécaniquement, notre équipe a montré que le diaphragme est activé jusqu’à la fin de l’expiration (activité tonique). Il n’est pas clair si cette activité tonique diaphragmatique compense pour l’absence de freinage laryngé liée à l’intubation endotrachéale. Objectif : Notre objectif est de déterminer si l’activité tonique diaphragmatique persiste après l’extubation chez les nourrissons et si elle peut être observée chez les enfants plus âgés. Méthode : Ceci est une étude observationnelle longitudinale prospective de patients âgés de 1 semaine à 18 ans admis aux soins intensifs pédiatriques (SIP), ventilés mécaniquement pour >24 heures et avec consentement parental. L’activité électrique du diaphragme (AEdi) a été enregistrée à l’aide d’une sonde nasogastrique spécifique à 4 moments durant le séjour aux SIP : en phase aigüe, pré et post-extubation et au congé. L’AEdi a été analysée de façon semi-automatique. L’AEdi tonique a été définie comme l’AEdi durant le dernier quartile de l’expiration. Résultats : 55 patients avec un âge médian de 10 mois (écart interquartile: 1-48) ont été étudiés. Chez les nourrissons (<1an, n=28), l’AEdi tonique en pourcentage de l’activité inspiratoire était de 48% (30-56) en phase aigüe, 38% (25-44) pré-extubation, 28% (17-42) post-extubation et 33% (22-43) au congé des SIP (p<0.05, ANOVA, avec différence significative entre enregistrements 1 et 3-4). Aucun changement significatif n’a été observé pré et post-extubation. L’AEdi tonique chez les patients plus âgés (>1an, n=27) était négligeable en phases de respiration normale (0.6mcv). Par contre, une AEdi tonique significative (>1mcv et >10%) a été observée à au moins un moment durant le séjour de 10 (37%) patients. La bronchiolite est le seul facteur indépendant associé à l’activité tonique diaphragmatique. Conclusion : Chez les nourrissons, l’AEdi tonique persiste après l’extubation et elle peut être réactivée dans certaines situations pathologiques chez les enfants plus âgés. Elle semble être un indicateur de l’effort du patient pour maintenir son VPFE. D’autres études devraient être menées afin de déterminer si la surveillance de l’AEdi tonique pourrait faciliter la détection de situations de ventilation inappropriée.
