Pelvic floor muscles training to reduce symptoms and signs of vulvovaginal atrophy : a case study

Objective: Vulvovaginal atrophy (VVA), caused by decreased levels of estrogen, is a common problem in aging women. Main symptoms of VVA are vaginal dryness and dyspareunia. First-line treatment consists of the application of local estrogen therapy (ET) or vaginal moisturizer. In some cases however, symptoms and signs persist despite those interventions. This case study describes a 77-year-old woman with severe VVA symptoms despite use of local ET and the addition of pelvic floor muscle (PFM) training to her treatment. Methods: A patient with stress urinary incontinence and VVA was referred to a randomized clinical trial on PFM training. On pretreatment evaluation while on local ET, she showed VVA symptoms on the ICIQ Vaginal Symptoms questionnaire and the ICIQ-Female Sexual Matters associated with lower urinary tract Symptoms questionnaire, and also showed VVA signs during the physical and dynamometric evaluation of the PFM. She was treated with a 12-week PFM training program. Results: The patient reported a reduction in vaginal dryness and dyspareunia symptoms, as well as a better quality of sexual life after 12 weeks of PFM training. On posttreatment physical evaluation, the PFMs' tone and elasticity were improved, although some other VVA signs remained unchanged. Conclusions: Pelvic floor muscle training may improve some VVA symptoms and signs in women taking local ET. Further study is needed to investigate and confirm the present case findings and to explore mechanisms of action of this intervention for VVA.

El legado de los flujos migratorios hacia la península de Crimea entre 1860 – 1991 en la crisis política de 2014

La presente investigación propone un análisis sobre la crisis política de Crimea en 2014 a partir del influjo que las migraciones desde Rusia han tenido en la historia reciente. Así, a partir de la evaluación de algunos de los momentos de inmigración más representativos en los últimos dos siglos (1860, 1928 y 1991) se vincula el proceso de construcción de la identidad de los inmigrantes -transversal en diferentes periodos históricos en Crimea- con el desarrollo de los eventos de 2014. Lo anterior permite identificar un cierto legado de la migración hacia Crimea en el desarrollo de la crisis, cuyo resultado principal ha sido la anexión de facto de Crimea a Rusia. Ésta no habría sido posible sin el particular ánimo de afinidad con la idea de Rusia –o Russianness- de la mayoría de los habitantes de la península, cuya presencia en la región se explica en parte, a través de los procesos migratorios antes descritos.

Healing wounds institutional strength, peacebuilding, and productive entrepreneurship – exploratory analysis on 23 departments of Colombia

Este estudio presenta un análisis exploratorio sobre la correlación entre la fortaleza institucional, las condiciones de paz, y el emprendimiento en una muestra de 23 departamentos en Colombia usando datos de 2014. Para llevar a cabo este objetivo se propusieron y construyeron tres índices siguiendo definiciones conceptuales seminales o estándares de evaluación internacional, a saber: 1) El Índice de Fortaleza Institucional, 2) El Índice de Construcción de Paz (construido a partir del índice de paz negativa y el índice de paz positiva) y 3) El Índice de Emprendimiento Productivo. Los resultados no muestran una correlación significativa entre todos los tres índices. Por un lado, existe una correlación significativa (p<0.05) entre los índices de fortaleza institucional y emprendimiento productivo. Por otro lado, existen correlaciones negativas no significativas entre los índices de paz positiva y fortaleza institucional, emprendimiento productivo y paz positiva y emprendimiento productivo y construcción de paz. En un segundo acercamiento, la población de los departamentos fue la variable con mayor número de correlaciones significativas (p<0.01) entre variables relacionadas con emprendimiento productivo, empleo, producto interno bruto, sofisticación industrial, innovación (patentes) y crimen. Finalmente, se discuten las conclusiones y las futuras investigaciones.

Sin división de género, el 30.93% de la población presento cáncer del sistema reproductor, el 18,56% digestivo y el 17,53% tegumentario. Se presentaron 2 grandes casos de agrupaciones espaciales en el territorio estudiado, una en el Barrio Pablo Neruda con 12 (21,05%) casos y en el casco Urbano de Sibaté con 38 (66,67%) casos. Conclusión: Se corroboro que el análisis geográfico con variables espacio temporales y de exposición, puede ser la herramienta para generar hipótesis sobre asociaciones de casos de cáncer con factores ambientales.

A influência do modelo e estrutura de recursos humanos na motivação e comprometimento dos trabalhadores: gestão interna versus Outsourcing

Com esta investigação, pretende-se fazer uma análise comparativa sobre o comprometimento e motivação dos trabalhadores, tendo como fator diferencial a gestão do recrutamento, de modo interno e a gestão por outsourcing. O objetivo principal é verificar se existem diferenças significativas nos dois grupos de trabalhadores, à luz de um quadro teórico muito vasto. Para concretizar esta análise foi elaborado um questionário on-line, com questões de escala manifestadas por afirmações elaboradas, com base no enquadramento teórico que constituiu a revisão da literatura, sobre motivação e comprometimento. Os resultados demonstraram que não existem diferenças significativas nos valores médios dos dois grupos na avaliação dos fatores de motivação, embora em ambos os grupos, se verifique uma grande vontade de darem mais de si à organização, de forma a superarem objetivos. Os valores de motivação revelaram-se muito baixos no geral, nos dois grupos. Em ambos os grupos apurou-se que há mais insatisfação face a fatores recompensatórios (tanto a nível material como imaterial): o salário e o reconhecimento do trabalho. Em relação ao comprometimento, verifica-se menor comprometimento por parte dos trabalhadores outsourcing, não numa análise de comparabilidade de médias gerais, mas numa análise de médias mais específicas de alguns fatores em avaliação: intenções de abandono. As médias das intenções de abandono foram mais visíveis neste grupo. No geral, ambos os trabalhadores dos dois grupos são movidos por um comprometimento instrumental, mais relacionado com as poucas alternativas que o mercado de trabalho dispõe , para uma evolução profissional; Abstract: The influence of human resource management structure in the motivation and commitment of employees: internal management versus outsourcing With this research aims to make a comparative analysis on the commitment and motivation of workers, with the differentiating factor the management of the internal mode recruitment and management by outsourcing. The main objective is to verify whether there are significant differences in the two groups of workers in the light of a very broad theoretical framework. To realize this analysis was prepared an online questionnaire with scale issues raised by elaborate statements, based on the theoretical framework that was the literature review of motivation and commitment. The results showed no significant differences in mean values of the two groups in the evaluation of the motivating factors, although in both groups, that there is a great desire to give more of themselves to the organization in order to overcome objectives. The motivation values proved to be very low in general, in both groups. In both groups it was found that there is more dissatisfaction with the recompensatórios factors (both material and immaterial level): wages and recognition of the work. Regarding the commitment, there is less commitment by the outsourcing workers, not an analysis of comparability of overall averages but a more average specific analysis of some factors reviewed abandonment of intentions. The average dropout intentions were more visible in this group. Overall, both employees of the two groups are driven by an instrumental commitment, more related to the few alternatives that the labor market has for professional development.

Stress Concentration Factor and Fatigue Life Evaluation in offshore tubular KT-Joints

In the last few decades, offshore field has grown fast especially after the notable development of technologies, explorations of oil and gas in deep water and the high concern of offshore companies in renewable energy mainly Wind Energy. Fatigue damage was noticed as one of the main problems causing failure of offshore structures. The purpose of this research is to focus on the evaluation of Stress Concentration Factor and its influence on Fatigue Life for 2 tubular KT-Joints in offshore Jacket structure using different calculation methods. The work is done by using analytical calculations, mainly Efthymiou’s formulations, and numerical solutions, FEM analysis, using ABAQUS software. As for the analytical formulations, the calculations were done according to the geometrical parameters of each method using excel sheets. As for the numerical model, 2 different types of tubular KT-Joints are present where for each model 5 shell element type, 3 solid element type and 3 solid-with-weld element type models were built on ABAQUS. Meshing was assigned according to International Institute of Welding (IIW) recommendations, 5 types of mesh element, to evaluate the Hot-spot stresses. 23 different types of unitary loading conditions were assigned, 9 axial, 7 in-plane bending moment and 7 out-plane bending moment loads. The extraction of Hot-spot stresses and the evaluation of the Stress Concentration Factor were done using PYTHON scripting and MATLAB. Then, the fatigue damage evaluation for a critical KT tubular joint based on Simplified Fatigue Damage Rule and Local Approaches (Strain Damage Parameter and Stress Damage Parameter) methods were calculated according to the maximum Stress Concentration Factor conducted from DNV and FEA methods. In conclusion, this research helped us to compare different results of Stress Concentration Factor and Fatigue Life using different methods and provided us with a general overview about what to study next in the future.

Effetto antinfiammatorio del trattamento emodialitico in pazienti con malattia renale cronica allo stadio terminale e COVID-19: confronto fra due filtri dializzatori (ATA vs PMMA)

Background I filtri dializzatori ad alto flusso potrebbero mitigare la “tempesta citochinica" nell'infezione da Sars-COV-2, ma il loro impatto nei pazienti in dialisi cronica non è accertato. Lo scopo delle studio è valutare l’effetto del filtro in triacetato asimmetrico di cellulosa (ATA) e in polimetilmetacrilato (PMMA) sui marcatori infiammatori in pazienti in dialisi cronica affetti da SARS-CoV-2. Metodi Si tratta di uno studio prospettico osservazionale su pazienti in trattamento emodialitico cronicp con COVID-19 arruolati da marzo 2020 a Maggio 2021.Le variabili cliniche, la conta leucocitaria, la IL-6, la proteina C-reattiva (PCR), la procalcitonina (PCT) e la ferritina sono state determinate al basale. I valori ematici di PCR, PCT, e IL-6 sono stati determinati pre e post-dialisi per ogni seduta effettuata (i valori ottenuti sono stati corretti per ’emoconcentrazione). I pazienti sono stati trattati con emodiafiltrazione online con un filtro ad alto flusso in PMMA o ATA. L’end-point primario è stato valutare l’effetto dei due filtri sulle molecole infiammatorie, in particolare sulla reduction ratio (RR) della IL-6. Risultati Dei 74 pazienti arruolati, 48 sono trati trattati con filtro ATA e 26 con filtro PMMA (420 vs 191 sedute dialitiche). La RR percentuale mediana della IL-6 è risultata maggiore nel gruppo ATA (17,08% IQR -9,0 - 40.0 vs 2,95% IQR -34,63 – 27,32. Anche le RR percentuale di PCR e PCT sono state maggiori nel gruppo ATA. La regressione logistica multipla avente come variabile dipendente una IL-6RR maggiore del 25%, ha mostrato che ATA determinava una maggiore probabilità di raggiungere l’outcome dopo correzione per i parametri infiammatori pre-dialisi (OR 1,721 95% CI 1,176 – 2,538 p=0,0056). Al contrario una PCR elevata riduceva la probabilità di ottenere una IL-6RR significativa (OR 0,9101 95% CI 0,868 – 0,949, p<0.0001). Conclusioni Nella nostra popolazione il filtro ATA ha mostrato un migliore profilo antiinfiammatorio.

Experimental evaluation of the z-resolution in different clinical Digital Breast Tomosynthesis systems using commercial phantoms

Digital Breast Tomosynthesis (DBT) is an advanced mammography technique based on the reconstruction of a pseudo-volumetric image. To date, image quality represents the most deficient section of DBT quality control protocols. In fact, related tests are not yet characterized by either action levels or typical values. This thesis work focuses on the evaluation of one aspect of image quality: the z-resolution. The latter is studied in terms of Artifact Spread Function (ASF), a function that describes the signal spread of a detail along the reconstructed focal planes. To quantify the ASF numerically, its Full Width at Half Maximum (FWHM) is calculated and used as a representative index of z-resolution. Experimental measurements were acquired in 24 DBT systems, of 7 different models, currently in use in 20 hospital facilities in Italy. The analysis, performed on the clinical reconstructed images, of 5 different commercial phantoms, lead to the identification of characteristic FWHM values for each type of DBT system. The ASF clearly showed a dependence on the size of the detail, providing higher FWHM values for larger objects. The z-resolution was found to be positively influenced by the acquisition angle: Fujifilm sistematically showed wider ASF profiles in ST mode (15°) than in HR mode (40°). However, no clear relationship was found between angular range and ASF, among different DBT systems, due to the influence of the peculiarities of each reconstruction algorithm. The experimental approach shown in this thesis work can be proposed as a z-resolution quality control test procedure. Contextually, the values found could be used as a starting point for identifying typical values to be included in the test, in a DBT protocol. Clearly, a statistically significant number of images is needed to do this. The equipment involved in this work is located in hospitals and is not available for research purposes, so only a limited amount of data was acquired and processed.

[construction Of Measurement Instruments In The Area Of Health].

Measurement instruments are an integral part of clinical practice, health evaluation and research. These instruments are only useful and able to present scientifically robust results when they are developed properly and have appropriate psychometric properties. Despite the significant increase of rating scales, the literature suggests that many of them have not been adequately developed and validated. The scope of this study was to conduct a narrative review on the process of developing new measurement instruments and to present some tools which can be used in some stages of the development process. The steps described were: I-The establishment of a conceptual framework, and the definition of the objectives of the instrument and the population involved; II-Development of the items and of the response scales; III-Selection and organization of the items and structuring of the instrument; IV-Content validity, V-Pre-test. This study also included a brief discussion on the evaluation of the psychometric properties due to their importance for the instruments to be accepted and acknowledged in both scientific and clinical environments.

Changes in parents' and self-reports of behavioral problems in Brazilian adolescents after behavioral treatment with urine alarm for nocturnal enuresis

PURPOSE: Compare parents' reports of youth problems (PRYP) with adolescent problems self-reports (APSR) pre/post behavioral treatment of nocturnal enuresis (NE) based on the use of a urine alarm. MATERIALS AND METHODS: Adolescents (N = 19) with mono-symptomatic (primary or secondary) nocturnal enuresis group treatment for 40 weeks. Discharge criterion was established as 8 weeks with consecutive dry nights. PRYP and APSR were scored by the Child Behavior Checklist (CBCL) and Youth Self-Report (YSR). RESULTS: Pre-treatment data: 1) Higher number of clinical cases based on parent report than on self-report for Internalizing Problems (IP) (13/19 vs. 4/19), Externalizing Problems (EP) (7/19 vs. 5/19) and Total Problem (TP) (11/19 vs. 5/19); 2) Mean PRYP scores for IP (60.8) and TP (61) were within the deviant range (T score ≥ 60); while mean PRYP scores for EP (57.4) and mean APSR scores (IP = 52.4, EP = 49.5, TP = 52.4) were within the normal range. Difference between PRYP' and APSR' scores was significant. Post treatment data: 1) Discharge for majority of the participants (16/19); 2) Reduction in the number of clinical cases on parental evaluation: 9/19 adolescents remained within clinical range for IP, 2/19 for EP, and 7/19 for TP. 3) All post-treatment mean scores were within the normal range; the difference between pre and post evaluation scores was significant for PRYP. CONCLUSIONS: The behavioral treatment based on the use of urine alarm is effective for adolescents with mono-symptomatic (primary and secondary) nocturnal enuresis. The study favors the hypothesis that enuresis is a cause, not a consequence, of other behavioral problems.

Estratégias de pré-concentração em eletroforese capilar: parte 2. Manipulação da velocidade da fase dispersa/secundária

This work describes CE preconcentration strategies based on the effect of manipulation of the disperse/secondary velocity. Introduced by Terabe et al. in 1984, micellar electrokinetic chromatography is a powerful separation approach that increases the usage of electrokinetic phenomena for the separation of nonionic compounds. The main disadvantage of MEKC is the low concentration sensitivity associated with the limited optical path length for on-capillary photometric detection and the limited volume of sample solution that can be injected. This paper compiles on-line concentration strategies for neutral analytes by sample stacking and sweeping in micellar electrokinetic chromatography.

Estratégias de pré-concentração em eletroforese capilar (CE): parte 1. Manipulação da velocidade eletroforética do analito

Capillary electrophoresis has become a well-established and routine-based separation technique. It is based on the differences between charged analyte mobility in aqueous or organic electrolytes. Its major limitation is the sensitivity due to small sample injection volumes and the narrow diameter of the capillaries, especially when UV detection is used. There are a number of ways to increase the concentration sensitivity. This report shows some on-line preconcentration strategies to perform it in free solution capillary electrophoresis that are based on manipulation of the analyte electrophoretic velocity during the sample introduction (stacking, field amplification and transient isotachophoresis).

Solid-phase microextraction for determination of 3-chloro-4-(dichloromethyl)-5-hydroxy-2[5H]-furanone in water

Solid-phase microextraction, using on-line bis(trimethylsilyl)trifluoroacetamide derivatisation, gas chromatography, and mass spectrometry, was evaluated in the quantification of 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) in water samples. Fibres encompassing a wide range of polarities were used with headspace and direct immersion sampling. For the immersion procedure, various parameters affecting MX extraction, including pH, salinity, temperature, and extraction time were evaluated. The optimised method (polyacrylate fibre; 20% Na2SO4; pH 2.0; 60 min; 20 °C) was applied for reservoir chlorinated water samples-either natural or spiked with MX (50 ng L-1 and 100 ng L-1). The recovery of MX ranged from 44 to 72%. Quantification of MX in water samples was done using external standard and the selected ion monitoring mode. Correlation coefficient (0.98%), relative standard deviation (5%), limit of detection (30 ng L-1) and limit of quantification (50 ng L-1) were obtained from calibration curve.
