RESUMEN

BACKGROUND: Chronic pelvic pain is a common disease that affects approximately 4% of women of reproductive age in developed countries. This number is estimated to be higher in developing countries, with a significant negative personal and socioeconomic impact on women. The lack of data on this condition in several countries, particularly those in development and in socially and biologically vulnerable populations such as the indigenous, makes it difficult to guide public policies. OBJECTIVES: To evaluate the prevalence of chronic pelvic pain (dysmenorrhea, dyspareunia, non-cyclical pain) and identify which variables are independently associated with the presence of the condition in indigenous women from Otavalo-Ecuador. DESIGN: A cross-sectional study was carried out including a sample of 2429 women of reproductive age between 14 and 49 years old, obtained from April 2022 to March 2023. A directed questionnaire was used, collected by bilingual interviewers (Kichwa and Spanish) belonging to the community itself; the number of patients was selected by random sampling proportional to the number of women estimated by sample calculation. Data are presented as case prevalence, odds ratio, and 95% confidence interval, with p < 0.05. RESULTS: The prevalence of primary dysmenorrhea, non-cyclic pelvic pain, and dyspareunia was, respectively, 26.6%, 8.9%, and 3.9%.all forms of chronic pain were independently associated with each other. Additionally, dysmenorrhoea was independently associated with hypertension, intestinal symptoms, miscegenation, long cycles, previous pregnancy, use of contraceptives and pear body shape. Pain in other sites, late menarche, exercise, and pear body shape were associated with non-cyclic pelvic pain. And, urinary symptoms, previous pregnancy loss, miscegenation, and pear body shape were associated with dyspareunia. CONCLUSION: The prevalence of primary dysmenorrhea and non-cyclical chronic pelvic pain was notably high, in contrast with the frequency of reported dyspareunia. Briefly, our results suggest an association between dysmenorrhoea and conditions related to inflammatory and/or systemic metabolic disorders, including a potential causal relationship with other manifestations of pelvic pain, and between non-cyclical pelvic pain and signs/symptoms suggesting central sensitization. The report of dyspareunia may be influenced by local cultural values and beliefs.

RESUMEN

Choosing appropriate reference genes or internal controls to normalize RT-qPCR data is mandatory for the interexperimental reproducibility of gene expression data obtained by RT-qPCR in most studies, including those on endometriosis. Particularly for miRNAs, the choice for reference genes is challenging because of their physicochemical and biological characteristics. Moreover, the retrograde menstruation theory, mesenchymal stem cells in menstrual blood (MenSCs), and changes in post-transcriptional regulatory processes through miRNAs have gained prominence in the scientific community as important players in endometriosis. Therefore, we originally explored the stability of 10 miRNAs expressions as internal control candidates in conditions involving the two-dimensional culture of MenSCs from healthy women and patients with endometriosis. Here, we applied multiple algorithms (geNorm, NormFinder, Bestkeeper, and delta Ct) to screen reference genes and assessed the comprehensive stability classification of miRNAs using RefFinder. Pairwise variation calculated using geNorm identified three miRNAs as a sufficient number of reference genes for accurate normalization. MiR-191-5p, miR-24-3p, and miR-103a-3p were the best combination for suitable gene expression normalization. This study will benefit similar research, but is also attractive for regenerative medicine and clinics that use MenSCs, miRNA expression, and RT-qPCR.

RESUMEN

X-ray ptychography and ptychographic computed tomography have seen a rapid rise since the advent of fourth-generation synchrotrons with a high degree of coherent radiation. In addition to quantitative multiscale structural analysis, ptychography with spectral capabilities has been developed, allowing for spatial-localized multiscale structural and spectral information of samples. The SWING beamline of Synchrotron SOLEIL has recently developed a nanoprobe setup where the endstation's first spectral and resonant ptychographic measurements have been successfully conducted. A metallic nickel wire sample was measured using 2D spectral ptychography in XANES mode and resonant ptychographic tomography. From the 2D spectral ptychography measurements, the spectra of the components of the sample's complex-valued refractive index, δ and ß, were extracted, integrated along the sample thickness. By performing resonance ptychographic tomography at two photon energies, 3D maps of the refractive index decrement, δ, were obtained at the Ni K-edge energy and another energy above the edge. These maps allowed the detection of impurities in the Ni wire. The significance of accounting for the atomic scattering factor is demonstrated in the calculation of electron density near a resonance through the use of the δ values. These results indicate that at the SWING beamline it is possible to conduct state-of-the-art spectral and resonant ptychography experiments using the nanoprobe setup.

RESUMEN

Three-phase induction motors are widely used in various industrial sectors and are responsible for a significant portion of the total electrical energy consumed. To ensure their efficient operation, it is necessary to apply control systems with specific algorithms able to estimate rotation speed accurately and with an adequate response time. However, the angular speed sensors used in induction motors are generally expensive and unreliable, and they may be unsuitable for use in hostile environments. This paper presents an algorithm for speed estimation in three-phase induction motors using the chaotic variable of maximum density. The technique used in this work analyzes the current signals from the motor power supply without invasive sensors on its structure. The results show that speed estimation is achieved with a response time lower than that obtained by classical techniques based on the Fourier Transform. This technique allows for the provision of motor shaft speed values when operated under variable load.

RESUMEN

Endometriosis is a complex disease that affects 10-15% of women of reproductive age. Familial studies show that relatives of affected patients have a higher risk of developing the disease, implicating a genetic role for this disorder. Little is known about the impact of germline genomic copy number variant (CNV) polymorphisms on the heredity of the disease. In this study, we describe a rare CNV identified in two sisters with familial endometriosis, which contain genes that may increase the susceptibility and progression of this disease. We investigated the presence of CNVs from the endometrium and blood of the sisters with endometriosis and normal endometrium of five women as controls without the disease using array-CGH through the Agilent 2x400K platform. We excluded common CNVs that were present in the database of genomic variation. We identified, in both sisters, a rare CNV gain affecting 113kb at band 3q12.2 involving two candidate genes: ADGRG7 and TFG. The CNV gain was validated by qPCR. ADGRG7 is located at 3q12.2 and encodes a G protein-coupled receptor influencing the NF-kappaß pathway. TFG participates in chromosomal translocations associated with hematologic tumor and soft tissue sarcomas, and is also involved in the NF-kappa B pathway. The CNV gain in this family provides a new candidate genetic marker for future familial endometriosis studies. Additional longitudinal studies of affected families must confirm any associations between this rare CNV gain and genes involved in the NF-kappaß pathway in predisposition to endometriosis.

RESUMEN

X-ray ptychography is a coherent diffraction imaging technique based on acquiring multiple diffraction patterns obtained through the illumination of the sample at different partially overlapping probe positions. The diffraction patterns collected are used to retrieve the complex transmittivity function of the sample and the probe using a phase retrieval algorithm. Absorption or phase contrast images of the sample as well as the real and imaginary parts of the probe function can be obtained. Furthermore, X-ray ptychography can also provide spectral information of the sample from absorption or phase shift images by capturing multiple ptychographic projections at varying energies around the resonant energy of the element of interest. However, post-processing of the images is required to extract the spectra. To facilitate this, ProSPyX, a Python package that offers the analysis tools and a graphical user interface required to process spectral ptychography datasets, is presented. Using the PyQt5 Python open-source module for development and design, the software facilitates extraction of absorption and phase spectral information from spectral ptychographic datasets. It also saves the spectra in file formats compatible with other X-ray absorption spectroscopy data analysis software tools, streamlining integration into existing spectroscopic data analysis pipelines. To illustrate its capabilities, ProSPyX was applied to process the spectral ptychography dataset recently acquired on a nickel wire at the SWING beamline of the SOLEIL synchrotron.

RESUMEN

Objetivo: Las restricciones de salud pública por el COVID-19 han jugado un papel central en la gestión de los programas de entrenamiento, en los que son escasos los estudios enfocados en la cuantificación de las cargas de entrenamiento en pretemporada, especialmente en futbolistas jóvenes. Por lo tanto, este estudio monitoreó la carga de entrenamiento interno (CEI) durante la pretemporada 2020/2021 durante la pandemia de COVID-19 de los jugadores de fútbol Sub-20. Método: Catorce futbolistas Sub-20 fueron monitoreados durante 7 semanas durante la pretemporada 2020/2021. El CEI de todas las sesiones de entrenamiento se estimó, en unidades arbitrarias, multiplicando el índice de esfuerzo percibido (IEP) para la sesión de entrenamiento completa por la duración de cada sesión de entrenamiento en minutos (IEP-sesión). También se estimaron la monotonía y la tensión de entrenamiento. Un ANOVA unidireccional de medidas repetidas comparó las variables dependientes a lo largo del tiempo. Resultados: En la cuarta semana, la CEI y la tensión de entrenamiento fueron estadísticamente más bajas en comparación con las otras semanas (P<0,05). El índice de monotonía de la semana 7 fue mayor en comparación con las semanas 1, 3 y 4 (P<0,05). Conclusión: Las restricciones sanitarias por el COVID-19 han afectado negativamente la carga de entrenamiento de pretemporada de los futbolistas Sub-20. Sin embargo, el índice de monotonía mostró que las cargas de entrenamiento estaban bien distribuidas durante las 7 semanas. (AU)

RESUMEN

Introduction: Obesity can complicate IgE-mediated allergic diseases. In the present study, we aimed to investigate the ability of obesity-related concentrations of leptin to modulate the in vitro effector and regulatory Fel d1-specific CD4+ T-cell subsets in patients allergic to cat, considered the third most common cause of respiratory allergy in humans. Methods: For this study, plasma and peripheral blood mononuclear cells (PBMC) from 30 cat-allergic patients with mild, moderate and severe respiratory symptoms were obtained. The PBMC cultures were stimulated with Fel d1 antigen (10 µg/mL) in the presence or absence of obesity-related leptin dose (50 ηg/mL). After 6 days, the levels of cytokines and IgE in the supernatants were evaluated by multiplex and ELISA, respectively. The frequency of different non-follicular (CXCR5-) and follicular (CXCR5+) Fel d1-specific CD4+ T cell subsets was determined by flow cytometry. The plasma levels of leptin and IgE anti-cat titers were evaluated by ELISA and ImmunoCAP, respectively. Results and conclusions: Fel d1 induced both IgE production and release of cytokines related to Th2, Th9 and Th17 cell phenotypes. Feld1 was more efficient in increasing the frequency of TFHIL-21- cells positive for IL-4, IL-5 and IL-13 than TFHIL-21+ cell subsets. Leptin favored the expansion Th2-like and Th9-like cells and TFHIL-21- cells positive for IL-4, IL-5 and IL-13, but reduced the proportion of conventional (Treg/Tr-1) and follicular (TFR) regulatory CD4+ T-cell subsets expressing or not CD39 marker. Finally, many of the imbalances between Fel d1-specific CD4+ T-cells were also correlated with plasma leptin and anti-Fel d1 IgE titers. In summary, hyperleptinemia should negatively impact on the severity of cat allergies by favoring the expansion of pathogenic Fel d1-specific CD4+ T-cell phenotypes and damaging the functional status of regulatory CD4+ T-cell subsets.

RESUMEN

OBJECTIVE: In the present study, our aim was to translate, adapt, and validate the Pelvic Health History Form (a quality of life [QoL] questionnaire) of the International Pelvic Pain Society (IPPS) from English to Portuguese. METHODS: The study was approved by the Ethics and Research Committee (CEP, in the Portuguese acronym) and the IPPS. The "Transcultural Adaptation" method comprised 5 stages: translation, synthesis, backtranslation, expert review, and pretest. Cultural adaptation and validation included cognitive interviews and statistical analysis of unanswered items (> 15%) in 14 clinic patients from CPP and endometriosis clinic at Santa Casa de São Paulo. RESULTS: Strong equivalences were established between the USA and Brazil questionnaires in terms of semantics, idioms, experiences, and concepts. Eighteen culturally inappropriate items were identified and adjusted using the revised response rate index. The subjective form underwent rigorous assessments, confirming its accurate measurement of intended targets. CONCLUSION: The methodology showed efficiency and equivalence, confirming its validity. The user-friendly format and inclusion of translated, adapted, and validated instruments in Portuguese make the form valuable for evaluating pelvic health, with potential for future research.

RESUMEN

Menstrual blood mesenchymal stem cells (MenSCs) have gained prominence in the endometriosis scientific community, given their multifunctional roles in regenerative medicine as a noninvasive source for future clinical applications. In addition, changes in post-transcriptional regulation via miRNAs have been explored in endometriotic MenSCs with a role in modulating proliferation, angiogenesis, differentiation, stemness, self-renewal, and the mesenchymal-epithelial transition process. In this sense, homeostasis of the miRNA biosynthesis pathway is essential for several cellular processes and is related to the self-renewal and differentiation of progenitor cells. However, no studies have investigated the miRNA biogenesis pathway in endometriotic MenSCs. In this study, we profiled the expression of eight central genes for the miRNA biosynthesis pathway under experimental conditions involving a two-dimensional culture of MenSCs obtained from healthy women (n = 10) and women with endometriosis (n = 10) using RT-qPCR and reported a two-fold decrease in DROSHA expression in the disease. In addition, miR-128-3p, miR-27a-3p, miR-27b-3p, miR-181a-5p, miR-181b-5p, miR-452-3p, miR-216a-5p, miR-216b-5p, and miR-93-5p, which have been associated with endometriosis, were identified through in silico analyses as negative regulators of DROSHA. Because DROSHA is essential for miRNA maturation, our findings may justify the identification of different profiles of miRNAs with DROSHA-dependent biogenesis in endometriosis.

RESUMEN

We aim to investigate the expression of genes (MAPK1 and CAPN2) and microRNAs (miR-30a-5p, miR-7-5p, miR-143-3p, and miR-93-5p) involved in adhesion and apoptosis pathways in superficial peritoneal endometriosis (SE), deep infiltrating endometriosis (DE), and ovarian endometrioma (OE), and to evaluate whether these lesions share the same pathophysiological mechanisms. We used samples of SE (n = 10), DE (n = 10), and OE (n = 10), and endometrial biopsies of these respective patients affected with endometriosis under treatment at a tertiary University Hospital. Endometrial biopsies collected in the tubal ligation procedure from women without endometriosis comprised the control group (n = 10). Quantitative real-time polymerase chain reaction was performed. The expression of MAPK1 (p < 0.0001), miR-93-5p (p = 0.0168), and miR-7-5p (p = 0.0006) was significantly lower in the SE group than in the DE and OE groups. The expression of miR-30a (p = 0.0018) and miR-93 (p = 0.0052) was significantly upregulated in the eutopic endometrium of women with endometriosis compared to the controls. MiR-143 (p = 0.0225) expression also showed a statistical difference between the eutopic endometrium of women with endometriosis and the control group. In summary, SE showed lower pro-survival gene expression and miRNAs involved in this pathway, indicating that this phenotype has a different pathophysiological mechanism compared to DE and OE.

RESUMEN

OBJECTIVE: To study the effect of intrauterine injection of C-X-C motif chemokine ligand 12 (CXCL12), also known as a stem cell chemoattractant (stromal cell-derived factor 1), on fertility and endometrial receptivity in mice with endometriosis. DESIGN: Laboratory study. SETTING: Academic Medical Center. ANIMAL(S): Fifty-six mice underwent chemotherapy and bone marrow transplantation. Thirty-six of these mice underwent either surgery to induce endometriosis (n = 20) or sham surgery (n = 16). INTERVENTION(S): Injection of CXCL12 as a potential therapeutic agent to improve fertility in endometriosis. MAIN OUTCOME MEASURE(S): Pregnancy rate, bone marrow-derived cell (BMDC) recruitment and endometrial receptivity markers. RESULT(S): The mice with or without endometriosis received a single uterine injection of either CXCL12 or placebo. Uterine injection of CXCL12 increased the pregnancy rates in a mouse model of endometriosis. Mice were euthanized after delivery, and implantation markers homeobox A11, alpha-v beta-3 integrin, and progesterone receptor were analyzed by immunohistochemistry, whereas green fluorescent protein positive BMDC recruitment was quantified by immunohistochemistry and immunofluorescence. The sham surgery groups without endometriosis had the highest cumulative pregnancy rate (100%) regardless of CXCL12 treatment. The endometriosis group treated with placebo had the lowest pregnancy rate. An increased pregnancy rate was noted in the endometriosis group after treatment with CXCL12. There was also an increase in BMDC recruitment and endometrial expression of progesterone receptor and alpha-v beta-3 integrin in the endometriosis group that received CXCL12 compared with that in the endometriosis group that received placebo. CONCLUSION(S): Uterine injection of CXCL12 increased the pregnancy rates in a mouse model of endometriosis. These results suggest that CXCL12 has a potential role as a therapeutic agent in women with infertility related to endometriosis and potentially other endometrial receptivity defects.

RESUMEN

Com o advento da revolução industrial, estudos mostram que o nível de qualidade do sono, estado de humor e a prática regular de atividades físicas são afetadas pela alta demanda que os indivíduos estão sujeitos para atender suas necessidades. O estudo teve como objetivo analisar os níveis da qualidade do sono, atividade física e estados de humor de comerciantes da empresa paraibana de abastecimento e serviços agrícolas. Cem comerciantes da Empasa de Campina Grande, participaram voluntariamente do estudo. Para análise do nível de atividade física dos comerciantes foi utilizado o questionário internacional de atividade física (IPAQ) versão curta, para mensurar os estados de humor foi utilizado a escala de Brunel (BRUMS) e o questionário de Pittsburgh para avaliar a qualidade de sono. Observou-se que a maioria dos comerciantes avaliados (55%) apresentam baixos níveis de atividade física. Além disso, em relação a qualidade de sono verifica-se que 69% dos comerciantes apresentaram níveis ruins de sono e 18% possuem a presença de distúrbio do sono. Verificou-se que os comerciantes apresentaram o perfil iceberg que representa uma boa saúde mental. No entanto, verifica-se alterações no perfil emocional principalmente em relação ao nível de percepção de tensão e fadiga. Conclui-se que os comerciantes apresentaram baixos níveis de atividade física e qualidade de sono ruim. Além disso, apresentam um perfil iceberg que representa boa saúde mental, mas apresentam elevação da percepção de tensão e fadiga.


With the advent of the industrial revolution, studies show that the level of sleep quality, mood and regular practice of physical activities are affected by the high demand that individuals are subject to to meet their needs. The study aimed to analyze the levels of sleep quality, physical activity and mood states of traders of the Paraíba company of supply and agricultural services. One hundred merchants from Empasa in Campina Grande voluntarily participated in the study. To analyze the level of physical activity of traders, the short version of the International Physical Activity Questionnaire (IPAQ) was used, to measure mood states, the Brunel scale (BRUMS) and the Pittsburgh questionnaire were used to assess sleep quality. It was observed that most traders evaluated (55%) have low levels of physical activity. In addition, in relation to sleep quality, 69% of traders had poor sleep levels and 18% had a sleep disorder. It was found that traders presented the iceberg profile that represents good mental health. However, there are changes in the emotional profile mainly in relation to the level of perception of tension and fatigue. It is concluded that traders had low levels of physical activity and poor sleep quality. In addition, they present an iceberg profile that represents good mental health, but they present an increase in the perception of tension and fatigue.


Con el advenimiento de la revolución industrial, los estudios demuestran que el nivel de calidad del sueño, el estado de ánimo y la práctica regular de actividades físicas se ven afectados por la alta exigencia a la que están sometidos los individuos para satisfacer sus necesidades. El estudio tuvo como objetivo analizar los niveles de calidad del sueño, actividad física y estado de ánimo de los comerciantes de una empresa de suministros y servicios agrícolas de Paraíba. Participaron voluntariamente del estudio cien comerciantes de Empasa de Campina Grande. Para analizar el nivel de actividad física de los comerciantes se utilizó la versión corta del Cuestionario Internacional de Actividad Física (IPAQ), la escala de Brunel (BRUMS) para medir los estados de ánimo y el cuestionario de Pittsburgh para evaluar la calidad del sueño. Se observó que la mayoría de los comerciantes evaluados (55%) presentan bajos niveles de actividad física. Además, en relación con la calidad del sueño, el 69% de los comerciantes tenía niveles de sueño deficientes y el 18% padecía algún trastorno del sueño. Se descubrió que los comerciantes presentaban el perfil del iceberg que representa una buena salud mental. Sin embargo, existen cambios en el perfil emocional principalmente en relación al nivel de percepción de tensión y fatiga. Se concluye que los comerciantes presentaban bajos niveles de actividad física y mala calidad del sueño. Además, presentan un perfil de iceberg que representa una buena salud mental, pero presentan una mayor percepción de tensión y fatiga.

RESUMEN

Abstract Objective To evaluate the use of misoprostol prior to hysteroscopy procedures regarding technical ease, the presence of side effects, and the occurrence of complications. Methods This is a retrospective, observational, analytical, case-control study, with the review of medical records of 266 patients followed-up at the Gynecological Videoendoscopy Sector of the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto of the Universidade de São Paulo (HCFMRP - USP, in the Portuguese acronym) from 2014 to 2019, comparing 133 patients who used the drug before the procedure with 133 patients who did not. Results The occurrence of postmenopausal uterine bleeding was the main indication for hysteroscopy and revealed a statistical difference between groups (p < 0.001), being present in 93.23% of the patients in the study group and in 69.7% of the patients in the control group. Only 2 patients (1.5%) in the study group reported adverse effects. Although no statistical differences were observed regarding the occurrence of complications during the procedure (p = 0.0662), a higher total number of complications was noted in the group that used misoprostol (n = 7; 5.26%) compared with the group that did not use the drug (n = 1; 0.75%), a fact that is clinically relevant. When evaluating the ease of the technique (measured by the complete performance of all steps of the hysteroscopy procedure), it was verified that although there was no difference between groups (p = 0.0586), the control group had more than twice as many incompletely performed procedures (n = 17) when compared with the group that used misoprostol previously (n = 8), which is also clinically relevant. Conclusion The use of misoprostol prior to hysteroscopy in our service indicated that the drug can facilitate the performance of the procedure, but not without side effects and presenting higher complication rates.


Resumo Objetivo Avaliação do misoprostol prévio à histeroscopia quanto à facilidade técnica, efeitos colaterais e a ocorrência de complicações durante o procedimento. Métodos Estudo analítico observacional retrospectivo tipo caso controle com revisão de prontuários de 266 pacientes do Setor de Videoendoscopia Ginecológica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto - Universidade de São Paulo (HCFMRP - USP), de 2014 a 2019, sendo comparadas 133 pacientes que utilizaram o medicamento prévio ao procedimento com 133 pacientes que não o utilizaram. Resultados Sangramento uterino após a menopausa foi a principal indicação de histeroscopia, apresentando diferença estatística (p < 0,001), estando presente em 93,23% das pacientes do grupo de estudo e em 69,17% das pacientes do grupo controle. Apenas 2 pacientes (1,5%) do grupo de estudo relataram efeitos adversos. Não foram observadas diferenças quanto à presença de complicações durante o procedimento (p = 0,0662), mas observamos um número total de complicações maior no grupo de estudo (n = 7; 5,26%) do que no grupo controle (n = 1; 0,75%), o que é clinicamente relevante. Não houve diferença entre os grupos quanto à facilidade técnica (p = 0,0586), mas o grupo controle apresentou mais do que o dobro de procedimentos não completamente realizados (n = 17) quando comparado com o grupo de estudo (n = 8), o que é clinicamente relevante. Conclusão O uso de misoprostol prévio à histeroscopia no nosso serviço demonstrou que ele pode facilitar a realização do procedimento, mas não é isento de efeitos colaterais e apresenta maiores taxas de complicações.

RESUMEN

The biological activities attributed to Lippia origanoides Kunth. vary according to the chemical composition of its essential oil, which can be related to weather factors. The aim of this research was the seasonal study of the essential oil chemical composition taken from L. origanoides accessions maintained in germplasm bank in vivo. The essential oil was extracted by hydrodistillation in Clevenger apparatus and identification of the components was done by GC-MS. We have identified 15 compounds of which carvacrol, p-cymene, thymol and methyl-ether-thymol were majority throughout the year for most accessions. In three accessions showed fluctuations in the production of the major compound during the year like the α-pinene, limonene and borneol. The essential oil showed variation in chemical composition throughout the year, the major compound in most of the accessions during the year is carvacrol. In some accessions, there are alterations of the majority component.
