RESUMO

OBJECTIVES: To evaluate uterine tamponade devices' effectiveness for atonic refractory postpartum haemorrhage (PPH) after vaginal birth and the effect of including them in institutional protocols. SEARCH STRATEGY: PubMed, EMBASE, CINAHL, LILACS, POPLINE, from inception to January 2021. STUDY SELECTION: Randomised and non-randomised comparative studies. OUTCOMES: Composite outcome including surgical interventions (artery ligations, compressive sutures or hysterectomy) or maternal death, and hysterectomy. RESULTS: All included studies were at high risk of bias. The certainty of the evidence was rated as very low to low. One randomised study measured the effect of the condom-catheter balloon compared with standard care and found unclear results for the composite outcome (relative risk [RR] 2.33, 95% CI 0.76-7.14) and hysterectomy (RR 4.14, 95% CI 0.48-35.93). Three comparative studies assessed the effect of including uterine balloon tamponade in institutional protocols. A stepped wedge cluster randomised controlled trial suggested an increase in the composite outcome (RR 4.08, 95% CI 1.07-15.58) and unclear results for hysterectomy (RR 4.38, 95% CI 0.47-41.09) with the use of the condom-catheter or surgical glove balloon. One non-randomised study showed unclear effects on the composite outcome (RR 0.33, 95% CI 0.11-1.03) and hysterectomy (RR 0.49, 95% CI 0.04-5.38) after the inclusion of the Bakri balloon. The second non-randomised study found unclear effects on the composite outcome (RR 0.95, 95% CI 0.32-2.81) and hysterectomy (RR 1.84, 95% CI 0.44-7.69) after the inclusion of Ebb or Bakri balloon. CONCLUSIONS: The effect of uterine tamponade devices for the management of atonic refractory PPH after vaginal delivery is unclear, as is the role of the type of device and the setting. TWEETABLE ABSTRACT: Unclear effects of uterine tamponade devices and their inclusion in institutional protocols for atonic refractory PPH after vaginal delivery.

RESUMO

Resumen Introducción: Ser cuidador de personas con dependencia funcional conlleva el riesgo de presentar deterioro de la calidad de vida, esto puede deberse a que la prolongación del cuidado altera la dinámica familiar y genera sobrecarga en el cuidador. Objetivo: 1) Identificar la relación entre funcionamiento familiar y calidad de vida del cuidador del adulto mayor y 2) Determinar la sobrecarga y calidad de vida del cuidador del adulto mayor. Metodología: Estudio descriptivo y correlacional, muestreo por bola de nieve, la muestra conformada por 86 cuidadores de un centro comunitario. Para las mediciones se utilizó el índice de Barthel, el Test de APGAR Familiar, la prueba de Zarit y la Escala de Calidad de Vida WHOQOL-BREF. Se aplicó la Prueba de Kolmogorov Smirnov y Prueba de Correlación de Spearman. Resultados: El 11.6% de los adultos mayores presentó dependencia total, la percepción de disfuncionalidad familiar grave representó el 3.5%. Los cuidadores con sobrecarga intensa fueron el 32.6%, el 8.1% percibió la calidad de vida deficiente. A mayor funcionamiento familiar mayor calidad de vida del cuidador (p<.05) y a mayor sobrecarga, menor calidad de vida del cuidador (p<.05) en todas las dimensiones. Conclusiones: Se observó que la sobrecarga y funcionalidad familiar están relacionadas con la calidad de vida del cuidador, por lo que se convierten en un escenario disciplinar que plantea la posibilidad de diseñar estrategias de intervención, centradas en la sobrecarga y el funcionamiento de la familia para el mejoramiento de la calidad de vida del cuidador.


Abstract Introduction: The prolonged provision of healthcare to functionally dependent persons can result in the deterioration on the caregiver's quality in terms of family dynamics and overload. Objectives: 1) To identify the relationship between the family dynamics and the quality of life of the caregiver of older adults; and 2) to estimate the quality of life and the overload of the caregiver of older adults. Methodology: This is a descriptive and correlational study with a snowball-derived sample of 86 caregivers in a communitarian center. The corresponding measures were estimated using the Barthel Index, the Family APGAR Test, the Zarit Test, and the WHOQOL-BREF Quality of Life Scale. The Kolmogorov-Smirnov and Spearman Correlation tests were calculated. Results: 11.6% of the older adults being cared showed total dependency. 3.5% of the caregiver's sample perceived having a severe family dysfunction. 32.6% of the sample were found having heavy overloads. 8.1% of the sample perceived having poor quality of life. In all dimensions, the better the family dynamics were, the better the quality of life of the caregivers was (p<.05), and the heavier the overload was, the worse the quality of life of the provider was (p<.05). Conclusions: It was noted that both, overload and family dynamics, are related to the quality of life of the caregivers of older adults; therefore, the design of intervention strategies should be focused on the overload and family dynamics of these professionals in order to improve their quality of life.

RESUMO

Dengue virus has shown a complex pattern of transmission across Latin America over the last two decades. In an attempt to explain the permanence of the disease in regions subjected to drought seasons lasting over six months, various hypotheses have been proposed. These include transovarial transmission, forest reservoirs and asymptomatic human virus carriers. Dengue virus is endemic in Mexico, a country in which half of the population is seropositive. Seropositivity is a risk factor for Dengue Hemorrhagic Fever upon a second encounter with the dengue virus. Since Dengue Hemorrhagic Fever can cause death, it is important to develop epidemiological mathematical tools that enable policy makers to predict regions potentially at risk for a dengue epidemic. We formulated a mathematical model of dengue transmission, considering both human behavior and environmental conditions pertinent to the transmission of the disease. When data on past human population density, temperature and rainfall were entered into this model, it provided an accurate picture of the actual spread of dengue over recent years in four states (representing two climactic conditions) in Mexico.

RESUMO

OBJECTIVE: To describe country-level stillbirth rates and their change over time in Latin America, and to measure the association of stillbirth rates with socio-economic and health coverage indicators in the region. DESIGN: Ecological study. SETTING: 20 countries of Latin America. POPULATION OR SAMPLE: Aggregated data from pregnant women with countries as units of analysis. METHODS: We used stillbirth estimates, and socio-economic and healthcare coverage indicators reported from 2006 to 2016 from UNICEF, United Nations Development Programme and World Bank datasets. We calculated Spearman's correlation coefficients between stillbirths rates and socioeconomic and health coverage indicators. MAIN OUTCOME MEASURES: National estimates of stillbirth rates in each country. RESULTS: The estimated stillbirth rate for Latin America for 2015 was 8.1 per 1000 births (range 3.1-24.9). Seven Latin America countries had rates higher than 10 stillbirths per 1000 births. The average annual reduction rate for the region was 2% (range 0.1-3.8%), with the majority of Latin America countries ranging between 1.5 and 2.5%. National stillbirth rates were correlated to: women's schooling (rS = -0.7910), gross domestic product per capita (rS = -0.8226), fertility rate (rS = 0.6055), urban population (rS = -0.6316), and deliveries at health facilities (rS = -0.6454). CONCLUSIONS: Country-level estimated stillbirth rates in Latin America varied widely in 2015. The trend and magnitude of reduction in stillbirth rates between 2000 and 2015 was similar to the world average. Socio-economic and health coverage indicators were correlated to stillbirth rates in Latin America. TWEETABLE ABSTRACT: Stillbirth rates decreased in Latin America but remain relatively high, with wide variations among countries.

RESUMO

BACKGROUND: Nowadays, neoadjuvant chemotherapy (nCT) in breast cancer is more and more standardized, not only in advanced tumours but also in those for which there is an attempt to achieve breast-conserving surgery. In literature, we can find evidences of the relationship between several types of tumours and systemic inflammatory response. Our objective is to analyse the prognostic value of blood parameters (lymphocytes, neutrophils, monocytes, lymphocyte-to-monocyte ratio (LMR), neutrophil-to-monocyte ratio (NMR) and neutrophil-to-lymphocyte ratio (NLR) in breast cancer (BC) patients treated with nCT. METHODS: A retrospective cohort of 150 breast cancer patients treated with nCT and subsequently with surgery was analysed. Data about the patients, histology, response to chemotherapy and peripheral blood values of lymphocytes, monocytes and neutrophils was collected, and used to calculate the LMR, NMR and NLR. Univariate and multivariate analyses were performed for the variables to see the relationship of the ratios to disease-free survival (DFS) and overall survival (OS). RESULTS: Patients with high LMR (≥5.46) and low NLR (<3.33) were associated with a lower percentage of relapse (P = 0.048 and P = 0.015, respectively) and, above all, NLR was associated with a better survival (P = 0.024), being those factors that predict a good progress. CONCLUSION: High LMR and low NLR can be considered as favourable prognostic factors in BC patients treated with nCT.

RESUMO

The authors studied the landscape components that favour the occurrence of anthrax in the Flooding Pampa grasslands (Buenos Aires province, Argentina). They made spatial locations of anthrax outbreaks diagnosed by registered veterinary laboratories in the study area's zone of influence. As variables for study, they differentiated areas that are flooded for 20% of the time or more from primary and secondary runoff channels. They also identified areas with low-productivity pasture. Logistic regression analysis of farm populations revealed that landscape components favouring the occurrence of anthrax outbreaks are shared runoff channels (odds ratio (OR) = 2.3; confidence interval (CI) = 1.2; 4.7) and > or = 40% low-productivity pasture (OR = 5.4; CI = 3.5; 8.3). Contrary to initial assumptions, susceptibility to flooding was not a significant variable (OR = 1.1; CI = 0.5; 2.1). The authors concluded that the first step in decision-making and ensuring more efficient implementation of future anthrax control and eradication plans was to identify risk variables.

RESUMO

AIM: The present investigation was designed to determine the in vivo antidiabetic effect of naringenin (NG) in normoglycaemic and diabetic rat models through blood glucose (GLU) measurements following acute and subchronic time periods. Possible modes of action of NG were investigated and its acute toxicity determined. METHODS: Normoglycaemic and non-insulin-dependent diabetes mellitus (NIDDM) rat models were treated for acute and subchronic (5 days) time periods with 50 mg/kg/day of NG. Blood biochemical profiles were determined after 5 days of the treatment in normoglycaemic and NIDDM rats using commercial kits for GLU, triglycerides (TG), total cholesterol (CHOL) and high-density lipoprotein (HDL). In order to elucidate its antidiabetic mode of action, NG was administered intragastrically and an oral glucose tolerance test performed using GLU and sucrose (2 g/kg) as substrates. The inhibitory effect of a single concentration of NG (10 microM) on 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) activity in vitro was determined. Finally, the preclinical safety and tolerability of NG was determined by toxicological evaluation in mice and rats using Organization for Economic Cooperation and Development (OECD) protocols. RESULTS: Intragastrically administered NG (50 mg/kg) induced a significant decrease in plasma GLU in normoglycaemic and NIDDM rat models (p < 0.05) following acute and subchronic time periods. After 5 days of administration, NG produced significant diminished blood GLU and TG levels in streptozotocin-nicotinamide-induced diabetic rats. The administration of NG to normal rats significantly increased the levels of TG, CHOL and HDL (p < 0.05). NG (5 and 50 mg/kg) induced a total suppression in the increase of plasma GLU levels after administration of substrates (p < 0.01), but NG did not produce inhibition of alpha-glucosidase activity in vitro. However, NG (10 microM) was shown to inhibit 11beta-HSD1 activity by 39.49% in a cellular enzyme assay. Finally, NG showed a Medium Lethal Dose LD(50) > 5000 mg/kg and ranking at level five based on OECD protocols. CONCLUSION: Our findings suggest that NG may exert its antidiabetic effect by extra-pancreatic action and by suppressing carbohydrate absorption from intestine, thereby reducing the postprandial increase in blood GLU levels.

RESUMO

OBJECTIVES: 1) To determine differences between sexes; 2) To determine differences by sex and age groups in symptom onset, time of evolution, clinical forms and probable associated causes. POPULATION AND SAMPLE: 83 consecutive patients with diagnosed PCP (X age = 50.9 SE 2.21). 25 males (30.1% x 51.2 years-old, SE 4.1) and 58 females (69.9%, X 50.8 years-old, SE 2.2). Patients with organic colon-rectum pathology (with the exception of hemorrhoidal pathology, proctologic surgery and active anus fissure) had been excluded. METHODS: Colonic Double-contrasted Rx, rectum-sigma endoscopy, and eventually a Colonofibroscopy Historic facts and syndromic protocol. Diagnosis criteria: 1) Perineal inspection: perineal contraction with pujo; 2) Rectal tact; 3) Ano-Rectum manometry with perfused system; 4) 150 ml Rectal balloon expulsion dynamic; 5) Utoreported signs and symptoms from a cuestionnaire ad hoc. Division into evolutive groups (continuous and intermittent). Division by age (< = 5, 5.1-25, > 25 years old). EXPERIMENT DESIGN: descriptive, comparative, correlation, prospective, simple blind. STATISTICS: Levene, descriptive, chi square, ANOVA, Kruskall-Wallis, Kendal tau b. RESULTS: 1) Difference in sex proportion was significative (p = 0.0001); 2) There were not differences between sexes in age media at the moment of the study (p = 0.92; 3) The continue evolutive form represented 77.1%, (p = 0.0001) but there weren't differences between sexes (p = 0.19) There weren't evolutive differences between age groups. (p = 0-78) 4) Age of onsec: x = 24.04 years-old, SE 2.02 (4-80 years-old), without differences between sexes (p = 0.16). 14.5% started before age of 5, 85% after that age, without differences between sexes (p = 0.07); 5) The time of evolution x = 26.7 years, SE 2.21, without differences between sexes (p = 0.25); 6) Potential causes were divides into tree categories: I "the patient doesn't remember associated facts" (30.1%, II: psychological or physical stress (39.8%), III: facts related to sexual trauma (30.1%). The differences (p = 0.0001); 7) Analyzed in general by sec, the most common cause was psychological-physical stress rather than sexual trauma in men, while among women sexual trauma was most common than psychological-physical stress (p = 0.03); 8) Analyzed by age groups: in the under 5 years-old group: main cause was "I don't remember". In 5.1-25-years-old group: sexual trauma; and psychological-physical stress was the main cause in > 25 years-old group (p 0.0001). CONCLUSIONS: 1) Women suffer from or consult much more frequently than man; 2) Once the disease is present, there would not be differences in age, age of onset, or time or evolution into proportions by sex; 3) The continue forms were the predominant ones; 4) The probable associated causes vary for each age group; 5) The sub-group "I don't remember" could represent in many cases a mismatch learning, but not constantly (there are cases of stress in familiar context); 6) In the subgroup "late childhood-adolescence" the predominant causes were traumatic experiences in erotic zones (rapping intent, sexual abuse, fantasies, elimination of parasites by the anus); 7) in the subgroup "older than 25 years-old" the predominant causes were physical stress, (violence, accidents, surgery) or emotional stress (familiar environment, social environment, affective losses). Some paradigmatic cases are presented. Anismus would be a complex situation involving an striated, voluntary, automatizated muscle (puborectalis) controlling independently genital-sexual, urinary and ano-rectal functions.

RESUMO

UNLABELLED: Cysteine-proteinase of Entamoeba histolytica have been considered implicated like important virulence factors in the pathogenesis of amebiasis. On the basis of the differences in ethnic gene that encodes to 30 kDa proteinase. The present study validated a strategy to differentiate strains of pathogenic and non-pathogenic Entamoeba histolytica by restriction patterns. MATERIALS AND METHODS: Thirteen stool samples with Entamoeba histolytica cyst from 4 asymptomatic and 9 symptomatic patients ages and sex different into Robinson' medium were used. DNA obtained was used by amplified gene ethnic and it was cut with restriction enzyme Taq I and Hinf I. RESULTS: All strains were cultivated into Robinson's medium. A 530 bp fragment which hybridated with probe for Entamoeba histolytica was obtained. By the way valuation by restriction patterns with Taq I and Hinf I show that two of four samples of asymptomatic patients belong to pathogenic strain. It agrees with control strain positive HM-1:IMSS. Last 9 belonged to symptomatic patients with pathogenic strain. CONCLUSIONS: These results indicate that ethnic amplified by polymerase chain reaction is insufficiently to establish differential diagnostic. Therefore is necessary carry out enzyme digestion to identify pathogenic strain.

RESUMO

El propósito de este trabajo fue determinar la presencia de enterovirus en materia fecal mediante la utilización de la técnica de concentración ácida (TCA). Para esto se analizaron muestras de 58 niños menores de cinco años con diagnóstico de Síndrome de Guillain-Barré (SGB), tanto por la técnica de rutina como por la técnica propuesta. Se utilizaron como testigos nueve muestras que salieron positivas con la técnica de rutina. En estas nueve muestras y en 22 más (31 casos) se aislaron e identificaron enterovirus tipo no polio mediante la TCA (53 por ciento), por lo tanto, se obtuvo 38 por ciento más de aislamientos utilizando la TCA. El aislamiento celular fue más exitoso en la línea celular RD (59 por ciento) que en la Hep-2c (41 por ciento), aunque los títulos virales que se obtuvieron fueron bajos en su mayoría (71 por ciento). La TCA mejora la detección de enterovirus, sin embargo, por ser más costosa y más laboriosa, únicamente se recomienda su uso en casos de importancia epidemiológica como: los compatibles a polio y cuyo resultado sea negativo al utilizar la técnica de rutina o en casos cuya muestra proviene de un caso de fallecimiento; siempre y cuando las muestras sean tomadas en los primeros 15 días después del inicio de la sintomatología.

RESUMO

The equilibrium adsorption at 20 degreesC of molybdophosphoric acid solutions, using ethanol-water as solvent, on titania was studied. The molybdenum adsorption isotherm showed a sigmoidal shape; low values of molybdenum adsorbed were observed for final equilibrium concentrations lower than 50 mg Mo/ml, and for higher concentrations, the adsorbed molybdenum amount almost reached a plateau. From this isotherm it could be concluded that the solute-support interaction was not strong. UV-visible and NMR spectra of the solutions before and after the adsorption on titania showed that the species PMo12O3-40 was present. This species also was observed by DRS in the wet samples and by NMR, FT-IR, and DRS, in the solid samples dried at room temperature and calcined at 255, 310, 365, and 425 degreesC, showing that the thermal stability of molybdophosphoric acid adsorbed on titania is similar to that of the bulk acid. The impregnating solutions and the impregnated solid changed with the time to a bluish color as a consequence of the formation of heteropoly blues which presented Mo6+ partially reduced to Mo5+. The XRD patterns indicated that the species adsorbed onto the support surface are highly dispersed like a noncrystalline form. Copyright 1998 Academic Press.

RESUMO

We used repeat isoelectric focusing to obtain cytoskeleton proteins of Giardia intestinalis with the characteristics of giardins and tubulins of the ventral disk. Their molecular weight and its variants by pH difference ranged between 30 and 45 kDa. Polypeptides with molecular weights between 97 and 115 kDa were also obtained. Our immunocytochemical studies showed that the proteins with high molecular weight were from the membrane of the trophozoites; in a smaller proportion we observed also proteins with molecular weights similar to those of giardins and tubulins.
