Identification and Analysis of SND1 as an Oncogene and Prognostic Biomarker for Lung Adenocarcinoma / 中国肺癌杂志

BACKGROUND@#Transcription factor (TF) can bind specific sequences that either promotes or represses the transcription of target genes, and exerts important effects on tumorigenesis, migration, invasion. Staphylococcal nuclease-containing structural domain 1 (SND1), which is a transcriptional co-activator, is considered as a promising target for tumor therapy. However, its role in lung adenocarcinoma (LUAD) remains unclear. This study aims to explore the role of SND1 in LUAD.@*METHODS@#Data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), Clinical Proteomic Tumor Analysis Consortium (CPTAC), and Human Protein Atlas (HPA) database was obtained to explore the association between SND1 and the prognosis, as well as the immune cell infiltration, and subcellular localization in LUAD tissues. Furthermore, the functional role of SND1 in LUAD was verified in vitro. EdU assay, CCK-8 assay, flow cytometry, scratch assay, Transwell assay and Western blot were performed.@*RESULTS@#SND1 was found to be upregulated and high expression of SND1 is correlated with poor prognosis of LUAD patients. In addition, SND1 was predominantly present in the cytoplasm of LUAD cells. Enrichment analysis showed that SND1 was closely associated with the cell cycle, as well as DNA replication, and chromosome segregation. Immune infiltration analysis showed that SND1 was closely associated with various immune cell populations, including T cells, B cells, cytotoxic cells and dendritic cells. In vitro studies demonstrated that silencing of SND1 inhibited cell proliferation, invasion and migration of LUAD cells. Besides, cell cycle was blocked at G1 phase by down-regulating SND1.@*CONCLUSIONS@#SND1 might be an important prognostic biomarker of LUAD and may promote LUAD cells proliferation and migration.

Based on LC-MS technology explored the metabolomics of Agrimonia pilosa intervening in non-small cell lung cancer A549 cells / 药学学报

The objective of this study was to analyze the effects on cell viability, apoptosis, and cell cycle of non-small cell lung cancer (NSCLC) A549 cells after intervention with Agrimonia pilosa (AP) and investigate Agrimonia pilosa anti-tumor activity in vitro. Meanwhile, liquid chromatography mass spectrometry (LC-MS) metabolomics technology was used to analyze the changes of cellular metabolites and metabolic pathways. The results of this study will provide a theoretical and experimental basis for investigating the mechanism of the effect of Agrimonia pilosa on non-small cell lung cancer A549 cells. The results showed that the cell nucleus of A549 cells crumpled and apoptosis occurred with the increase of drug concentration. The survival rate of the cells decreased, and the inhibition rate reached 21.5% and 91.74% under the low and high dose conditions, respectively. Lactate dehydrogenase (LDH) content increased (P < 0.05). Metabolomics results showed significant differences in metabolism between groups, thirty-three distinct metabolites including LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) were deduced. The pathway enrichment showed that the Agrimonia pilosa plays an anti-tumor role mainly by regulating the metabolism of glycerophosphate and purine in A549 cells, in which the effect on glycerophosphate metabolism pathway was most significant. The results of combined pharmacodynamics suggested that Agrimonia pilosa might induce apoptosis and inhibit the growth of A549 cells by regulating LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) metabolites in A549 cells.

A network pharmacology-based approach to explore mechanism of kaempferol-7 -O -neohesperidoside against prostate cancer / 中国药理学通报

Aim To explore the effect of kaempferol-7- 0-neohesperidoside (K70N) against prostate cancer (PCa) and the underlying mechanism. Methods The effect of K70N on the proliferation of PCa cell lines PC3, DU145, C4-2 and LNCaP was detected using CCK8 assay. The effect of K70N on migration ability of DU145 cells was determined by wound healing assay. The targets of K70N and PCa were screened from SuperPred and other databases. The common targets both related to K70N and PCa were obtained from the Venny online platform, a protein-protein interaction network (PPI) was constructed by the String and Cyto- scape. Meanwhile, the GO and KEGG functional enrichment were analyzed by David database. Then, a "drug-target-disease-pathway" network model was constructed. Cell cycle of PCa cells treated with K70N was analyzed by flow cytometry. The expressions of cycle-associated proteins including Skp2, p27 and p21 protein were detected by Western blot. Molecular docking between Skp2 and K70N was conducted by Sybyl X2. 0. Results K70N significantly inhibited the proliferation and migration of PCa cells. A total number of 34 drug-disease intersection targets were screened. The String results showed that Skp2 and p27, among the common targets, were the key targets of K70N for PCa treatment. Furthermore, GO and KEGG functional en-richment indicated that the mechanism was mainly related to the cell cycle. Flow cytometry showed that K70N treatment induced cell cycle arrest at the S phase. Compared with the control group, the protein expression level of Skp2 was significantly down-regulated, while the protein expression levels of p27 and p21 were up-regulated. The network molecular docking indicated that the ligand K70N had a good binding ability with the receptor Skp2. Conclusions K70N could inhibit the proliferation and migration of PCa cells, block the cell cycle in the S phase, which may be related to the regulation of cell cycle through the Skp2- p27/p21 signaling pathway.

Curcumin Induces Cycle Arrest of Colon Cancer HCT116 Cells via JAK1/STAT1/p21 Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the effect of curcumin on the cycle arrest of human colon cancer HCT116 cells and decipher the possible molecular mechanism. MethodThe methyl thiazolyl tetrazolium （MTT） method was employed to examine the effects of curcumin （0， 12.5， 25， 50， 75， 100 μmol·L-1） and 5-fluorouracil （5-FU， 600 μmol·L-1） on the proliferation of HCT116 cells at different time points （24， 48， 72 h）. Flow cytometry was employed to examine the cycle of HCT116 cells treated with curcumin （0， 25， 50， 75 μmol·L-1） and 5-FU. Western blot was employed to determine the expression of proteins in the Janus kinase 1 （JAK1）/signal transducer and activator of transcription 1 （STAT1） /cyclin-dependent kinase inhibitor 1A （p21） pathway in HCT116 cells. The binding of STAT1 to p21 promoter region was detected by chromatin immunoprecipitation （ChIP）. Small interfering RNA （siRNA） was employed to measure the role of STAT1 in regulating the expression of p21 and that of JAK1 in regulating the activation of STAT1 by Western blot and cellular immunofluorescence， respectively. ResultCompared with the blank group， the HCT-116 cells treated with curcumin and 5-FU showed decreased viability （P<0.05）， increased proportions of cells in the G0/G1 phase （P<0.05）， decreased proportions of cells in the S phase and G2/M phase （P<0.05）， down-regulated protein level of phosphorylated p21 （P<0.05）， and up-regulated protein level of p21 （P<0.05）. Compared with the curcumin group， the p21 siRNA+ curcumin group presented decreased proportion of cells in G0/G1 phase （P<0.05）. Compared with the blank group， curcumin elevated the level of phosphorylated STAT1 （p-STAT1） （P<0.05）. Compared with the curcumin group， the curcumin + STAT1 siRNA group showcased up-regulated protein level of p21 in HCT116 cells （P<0.05）. The mechanism study showed that curcumin treatment enhanced the enrichment of STAT1 in the p21 promoter region （P<0.05） compared with the blank group. Compared with the blank group， curcumin up-regulated the level of phosphorylated JAK1 （p-JAK1） （P <0.05）. Compared with the curcumin group， the curcumin + STAT1 siRNA group demonstrated up-regulated protein levels of p-STAT1 and p21 in HCT116 cells （P<0.05）. ConclusionCurcumin may induce the cycle arrest of human colon cancer HCT116 cells by activating the JAK1/STAT1/p21 signaling pathway.

Effects of occupational radiation exposure on peripheral blood lymphocyte count and cell cycle in logging workers / 中国辐射卫生

Objective To investigate the effects of prolonged low-dose neutron-γ radiation on peripheral blood lymphocytes of logging workers. Methods The health information of workers in a logging company was collected by on-site blood sample collection and questionnaire survey. Individual doses of γ and neutron radiation were recorded using LiF elements and CR-39, respectively. Lymphocyte count in peripheral blood was measured by blood cytometer. Cell cycle and cyclins were detected by flow cytometry. Results The annual dose of some logging workers exceeded 5 mSv. Lymphocyte counts showed a difference of 15% between the group exposed to the lowest annual dose of 0–1 mSv (mean: 2.45 × 109/L) and the group exposed to the highest annual dose of 5–25 mSv (mean: 2.08 × 109/L). In comparison to pre-shift workers, logging workers exhibited a G1-phase arrest in the lymphocyte cycle, along with increased expression of cyclins p21 and CDK2. Conclusion Prolonged exposure to low-dose neutron-γ radiation leads to reduced lymphocyte counts as well as changes in lymphocyte cycle and cyclin expression.

Mechanism of Qizhu Kang'ai Prescription for Inhibiting Proliferation of Hepatocellular Carcinoma by Regulating Tumor Metabolic Reprogramming via PCK1/Akt/p21 Signal Axis / 中国实验方剂学杂志

ObjectiveTo study the effect of Qizhu Kang'ai prescription （QZAP） on the gluconeogenesis enzyme phosphoenolpyruvate carboxykinase 1 （PCK1） in the liver of mouse model of liver cancer induced by diethylnitrosamine （DEN） combined with carbon tetrachloride （CCl4） and Huh7 cells of human liver cancer， so as to explore the mechanism on regulating metabolic reprogramming and inhibiting cell proliferation of liver cancer cells. MethodDEN combined with CCl4 was used to construct a mouse model of liver cancer via intraperitoneal injection. A normal group， a model group， and a QZAP group were set up， in which QZAP （3.51 g·kg-1） or an equal volume of normal saline was administered daily by gavage， respectively. Serum and liver samples were collected after eight weeks of intervention. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， γ-glutamyltransferase （γ-GT）， and alpha-fetoprotein （AFP） in mice were detected to evaluate liver function changes of mice in each group. Hematoxylin-eosin （HE） staining and Sirius red staining were used to observe pathological changes in liver tissue. In the cell experiment， Huh7 cells were divided into blank group， QZAP low， medium， and high dose groups and/or PCK1 inhibitor （SKF-34288 hydrochloride） group， and Sorafenib group. The corresponding drug-containing serum and drug treatment were given， respectively. Cell counting kit-8 （CCK-8） method， colony formation experiment， Edu fluorescent labeling detection， intracellular adenosine triphosphate （ATP） content detection， and cell cycle flow cytometry detection were used to evaluate the proliferation ability， energy metabolism changes， and change in the cell cycle of Huh7 cells in each group. Western blot was used to detect the protein expression levels of PCK1， serine/threonine kinase （Akt）， phosphorylated Akt （p-Akt）， and cell cycle-dependent protein kinase inhibitor 1A （p21）. ResultCompared with the model group， the pathological changes such as cell atypia， necrosis， and collagen fiber deposition in liver cancer tissue of mice in the QZAP group were alleviated， and the number of liver tumors was reduced （P<0.01）. The serum ALT， AST， γ-GT， and AFP levels were reduced （P<0.01）. At the cell level， compared with the blank group， low， medium， and high-dose groups of QZAP-containing serum and the Sorafenib group could significantly reduce the survival rate of Huh7 cells （P<0.01） and the number of positive cells with Edu labeling （P<0.01） and inhibit clonal proliferation ability （P<0.01）. The QZAP groups could also reduce the intracellular ATP content （P<0.05） and increase the distribution ratio of the G0/G1 phase of the cell cycle （P<0.05） in a dose-dependent manner. Compared with the model group and blank group， PCK1 and p21 protein levels of mouse liver cancer tissue and Huh7 cells in the QZAP groups were significantly reduced （P<0.05，P<0.01）， and the p-Akt protein level was significantly increased （P<0.01）. Compared with the blank group， the ATP content and cell survival rate of Huh7 cells in the SKF-34288 hydrochloride group were significantly increased （P<0.05）， but there was no statistical difference in the ratio of Edu-positive cells and the proportion of G0/G1 phase distribution. Compared with the SKF-34288 hydrochloride group， the QZAP combined with the SKF-34288 hydrochloride group significantly reduced the ATP content， cell survival rate， and Edu-positive cell ratio of Huh7 cells （P<0.05） and significantly increased the G0/G1 phase distribution proportion （P<0.05）. ConclusionQZAP may induce the metabolic reprogramming of liver cancer cells by activating PCK1 to promote Akt/p21-mediated tumor suppression， thereby exerting an anti-hepatocellular carcinoma proliferation mechanism.

Comparison of menstrual cycle irregularities among young women based on coronavirus disease 2019 infection status: a cross-sectional study

SUMMARY OBJECTIVE: The coronavirus disease 2019 pandemic that has emerged recently has significantly affected and continues to affect our lives. The Severe Acute Respiratory Syndrome Coronavirus 2 virus has significant effects on women's health due to gender-related physiological differences. The aim of this study was to compare the menstrual cycle status of young women according to their status of having had coronavirus disease 2019. METHODS: This descriptive cross-sectional study was conducted with 220 young women aged between 18 and 25 years who received at least one dose of coronavirus disease 2019 vaccine. The study data were collected as a survey on the online platform. RESULTS: The descriptive characteristics of young women who had had and had not had coronavirus disease 2019 were distributed homogeneously between the groups (p>0.05). Furthermore, there was no statistical difference in terms of menstrual cycle patterns (p>0.05). The mean scores from the Premenstrual Syndrome Scale and its subscales and the mean scores from the COVID Stress Scale and its subscales were similar in both groups, and no statistically significant difference was identified (p>0.05). CONCLUSION: Although menstrual cycle irregularities due to coronavirus disease 2019 have been reported, these effects are usually observed during the pandemic. A decrease in stress and anxiety with the end of the pandemic may explain the return of the menstrual cycle to normal.

Impact of menstrual cycle on smoking cessation: A review / El impacto del ciclo menstrual en el abandono de tabaco: Una revisión

Abstract Background Information on the way menstrual cycle phases can influence the achievement of tobacco abstinence is contradictory. Objective A scope review was conducted to determine the effect of the menstrual cycle on tobacco abstinence, considering the phases of the cycle, hormone levels, and premenstrual syndrome. Method A literature search was conducted in Scopus, PubMed, MEDLINE, and PsycINFO databases. Ten articles comparing the phases of the menstrual cycle or analyzing the association between premenstrual syndrome and a withdrawal condition (length of abstinence or withdrawal symptoms) were included. Results Two main results were identified: 1) there is no difference in withdrawal symptoms and craving between menstrual cycle phases and 2) abstinence rates in the studies were higher during the luteal phase. Discussion and conclusion The advisability of suggesting that women wishing to quit smoking should begin to do so at the start of the luteal phrase is discussed. However, smoking cessation interventions must consider all the symptoms experienced during the luteal phase.

Resumen Antecedentes La información sobre cómo las diferentes fases del ciclo menstrual pueden influir en el logro de la abstinencia de tabaco es contradictoria. Objetivo Se realizó una revisión de alcance con el fin identificar la evidencia relacionada al efecto del ciclo menstrual en la abstinencia de tabaco, considerando las variables fases del ciclo, niveles hormonales y síndrome premenstrual. Método Se llevó a cabo una búsqueda de la literatura en las bases de datos Scopus, PubMed, MEDLINE y PsycINFO. Se incluyeron diez artículos que realizaban comparaciones entre las fases del ciclo menstrual o bien análisis entre el síndrome premenstrual y una condición de abstinencia (tiempo de abstinencia o síntomas de abstinencia). Resultados Se identificaron dos resultados principales 1) no hay diferencia en los síntomas de abstinencia y el deseo por fumar entre las fases del ciclo menstrual y 2) las tasas de abstinencia de los estudios fueron mayores durante la fase lútea. Discusión y conclusión Se discute si en la fase lútea se puede sugerir el inicio de la abstinencia en mujeres que buscan dejar de fumar, sin embargo, las intervenciones para dejar de fumar deben tomar en cuenta todos los síntomas que se experimentan en la fase lútea.

Cycle threshold predicted mortality in a cohort of patients with hematologic malignancies infected with SARS-CoV-2 / El umbral de ciclado predijo la mortalidad en una cohorte de pacientes conneoplasias hematológicas infectados con SARS-CoV-2 / Microbiología clinica y enfermedades infecciosas

Abstract When a SARS-CoV-2 RT-qPCR test is performed, it may determine an indirect measureof viral load called cycle threshold (Ct). Respiratory samples with Ct <25.0 cycles are consideredto contain a high viral load. We aimed to determine whether SARS-CoV-2 Ct at diagnosis couldpredict mortality in patients with hematologic malignancies (lymphomas, leukemias, multiplemyeloma) who contracted COVID-19. We included 35 adults with COVID-19 confirmed by RT-qPCR performed at diagnosis. We evaluated mortality due to COVID-19 rather than mortalitydue to the hematologic neoplasm or all-cause mortality. Twenty-seven (27) patients survivedand 8 died. The global mean Ct was 22.8 cycles with a median of 21.7. Among the survivors,the mean Ct was 24.2, and the median Ct value was 22.9 cycles. In the deceased patients, themean Ct was 18.0 and the median Ct value was 17.0 cycles. Using the Wilcoxon Rank Sum test,we found a significant difference (p = 0.035). SARS-CoV-2 Ct measured in nasal swabs obtainedat diagnosis from patients with hematologic malignancies may be used to predict mortality.

Resumen Cuando se realiza una RT-qPCR para SARS-CoV-2, es posible determinar una medidaindirecta de la carga viral llamada umbral de ciclado (Ct). Las muestras respiratorias con Ct<25,0 ciclos se consideran de alta carga viral. Nos propusimos determinar si el Ct para SARS-CoV-2 al diagnóstico predice la mortalidad en pacientes con neoplasias hematológicas (linfomas,leucemias, mielomas) que contrajeron COVID-19. Incluimos 35 adultos con COVID-19 confirmadopor RT-qPCR al diagnóstico. Evaluamos la mortalidad por COVID-19, no la mortalidad por la neo-plasia hematológica o la mortalidad por cualquier causa. De los 35 pacientes, 27 sobrevivierony 8 fallecieron. El Ct global medio fue 22,8 ciclos con una mediana de 21,7 ciclos. Entre lossobrevivientes, el Ct medio fue 24,2 ciclos con una mediana de 22,9 ciclos. Entre los fallecidos,el Ct medio fue 18,0 y el Ct mediano fue 17,0 ciclos. Empleando la prueba de suma de rangosde Wilcoxon, encontramos una diferencia significative (p = 0,035). En pacientes con neoplasiashematológicas infectados con coronavirus, el Ct de SARS-CoV-2 medido en hisopados nasales almomento del diagnóstico podría ser utilizado para predecir la mortalidad.

Vacuna contra la COVID-19 y menstruación, desde el desconocimiento a la información: revisión sistemática / Vaccine against COVID-19 and menstruation, from ignorance to information: a systematic review

La creación de una vacuna para enfrentar la pandemia de COVID-19 conllevó un vacío de información sobre las posibles alteraciones del ciclo menstrual. El objetivo fue verificar las posibles alteraciones que se pudiesen haber generado en el ciclo menstrual de las mujeres posterior a la inoculación de la vacuna contra la COVID-19. Se realizó una revisión sistemática en las bases bibliografías Medline, Medline Complete, LILACS, CINAHL y ScIELO, utilizando los descriptores “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” y “Menstruation disturbances”. Mediante la utilización del protocolo PRISMA, de los 319 artículos localizados, 17 fueron incluidos en el análisis. La mayoría de los estudios incluyeron, principalmente, las vacunas Pfizer, Moderna, AstraZeneca y Johnson&Johnson/Janssen con una a tres dosis administradas. El porcentaje de ciclos menstruales alterados fue del 8,0% al 77,8%, y la alteración con mayor frecuencia referida fue la duración del ciclo menstrual, que fue desde 0,3 hasta 12 días de retraso de la menstruación. Todos los estudios refieren cambios en el ciclo menstrual con diversas prevalencias, con y sin significación estadística; sin embargo, también concluyen que estas alteraciones son reversibles y en un corto periodo de tiempo.

The creation of a vaccine to face the COVID-19 pandemic, led to an information gap on possible alterations of the menstrual cycle. The objective was to verify the possible alterations that could have been generated in the menstrual cycle of women, after the inoculation of the vaccine against COVID-19. A systematic review was carried out in the Medline, Medline Complete, LILACS, CINAHL and ScIELO bibliographic databases, using the descriptors “Women”, “Woman”, “Fertile period”, “Vaccination”, “Mass vaccination”, “Immunization”, “COVID-19 vaccines”, “SARS-CoV-2 infection”, “COVID-19”, “Menstrual cycle”, “Menstruation”, “Endometrial cycle”, “Dysmenorrhea” and “Menstruation disturbances”. Using the PRISMA protocol, of the 319 articles located, 17 were included in the analysis. Most of the studies mainly included the Pfizer, Moderna, AstraZeneca and Johnson&Johnson/Janssen vaccines with one to three doses administered. The percentage of altered menstrual cycles ranged from 8.0% to 77.8%, and the most frequently reported alteration was the length of the menstrual cycle, which occurred from 0.3 to 12 days late in menstruation. All the studies refer to changes in the menstrual cycle with different prevalences, with and without statistical significance; however, the same studies also conclude that these alterations are reversible and in a short period of time.

Pediatría: un enfoque integral desde sus orígenes hasta la actualidad / Pediatrics: A Comprehensive Approach From its Origins to Present Day / Pediatria: uma abordagem integral desde suas origens até o presente

El término pediatría surge del griego paidos (niño) e iatrea (curación). Inicialmente, la pediatría fue descrita como una de las ramas independientes de la medicina en Europa Central durante la segunda mitad del siglo XIX; se independizó de áreas como la obstetricia y la medicina interna de forma progresiva. Fue descrita por primera vez en 1722 en el tratado Paedojatreja práctica por el profesor de anatomía y teoría médica Theodor Zwinger de la Universidad de Basileam. Los escritos más antiguos de los que se tiene conocimiento de enfermedades en población pediátrica datan de 2100 a. de C., en donde primaba el componente mágico-religioso (1). En Colombia, sus primeros reportes inician en 1868 con el inicio de la época denominada «Segunda etapa de la medicina colombiana¼, tras la fundación de la Universidad de los Estados Unidos de Colombia en Bogotá, en donde se implementa la cátedra de obstetricia y patología especial de las mujeres y niños, por el médico y presidente Santos Acosta. Posteriormente, se separan las asignaturas de obstetricia y patología especial de las mujeres, originándose la cátedra opcional de patología e higiene de la infancia. En 1891, José Ignacio Barberi, bogotano graduado de la Universidad Nacional de Colombia en el año 1881, se convierte en el primer especialista en dictar la asignatura Clínica infantil. En 1911, con la cátedra de pediatría en la Universidad de Antioquia, nace la especialidad en ese departamento, y el 27 de julio de 1917 se funda la Sociedad Colombiana de Pediatría, la cual propende por el bienestar de los niños y adolescentes, su familia y la sociedad, para el desarrollo de la pediatría como disciplina del hombre (2,3).

The term pediatrics comes from the Greek paidos (child) and iatrike (medicine). Initially, pediatrics was described as one of the independent branches of medicine in Central Europe during the second half of the 19th century. It progressively became independent from areas such as obstetrics and internal medicine. It was first described in 1722 in the treatise Paedojatreja práctica by the professor of anatomy and medical theory Theodor Zwinger of the University of Basel. The oldest known works on diseases in the pediatric population date back to 2100 B.C., in which the magical-religious component was predominant (1). In Colombia, its first reports begin in 1868 with the start of the period called the "Second stage of Colombian medicine". After the foundation of the Universidad de los Estados Unidos de Colombia in Bogotá. The subject of obstetrics and special pathology of women and children was implemented by physician and President Santos Acosta. Subsequently, the subjects of obstetrics and special pathology of women were separated, creating the optional subject of childhood pathology and hygiene. In 1891, José Ignacio Barberi, a Bogotá native graduated from the Universidad Nacional de Colombia in 1881, became the first specialist to teach the subject Children's medicine. In 1911, the specialization was born in the department of Antioquia with the subject of pediatrics at University of Antioquia. The Colombian Society of Pediatrics was founded on July 27, 1917, which advocates for the well-being of children and adolescents, their families and society, to develop pediatrics as a human discipline (2,3).

Características e diferenças nos sintomas dos períodos menstrual e pré-menstrual em mulheres sedentárias / Characteristics and differences in the symptoms of themenstrual and premenstrual periods in sedentary women

Objetivo: estabelecer as diferenças de sintomas físicos e mentais nos períodos menstrual e pré-menstrual em mulheres sedentárias. Métodos: estudo transversal, por questionário, respondido por 77 mulheres saudáveis, de 18 a 35 anos, sedentárias e que não fizessem uso de anticoncepcional continuamente. O questionário incluiu questões sobre dados antropométricos, sintomas físicos e mentais nos períodos menstrual e pré-menstrual. O teste Mann-Whitney comparou os momentos menstrual e pré-menstrual. Resultados: no período menstrual, em uma escala numérica de 0 a 10 pontos, observou-se maiores queixas de dor (7/10), mau humor (7/10), desânimo (8/10), irritabilidade (8/10), ansiedade (7/10), choro (7/10), raiva (9/10) e impacto nas atividades de vida diárias (AVDs) (7/10). Já no período pré-menstrual observou-se queixas de cefaleia (5/10), edema/retenção hídrica (6/10), mau humor (6/10), tristeza (6/10), irritabilidade (7/10), choro (7/10) e raiva (6/10). Quando comparados os períodos menstrual e pré-menstrual, o período menstrual apresentou piores sintomas de dismenorreia (P<0,05), lombalgia (P<0,05), dor nos membros inferiores (P<0,05), dificuldade de concentração (P<0,05), aumento do sono (P<0,05) e desânimo (P<0,05). As voluntárias apontaram 14 sintomas piores, com intensidade igual ou maior que 7 no período menstrual, e apresentaram 9 sintomas com intensidade igual ou maior que 7 no período pré-menstrual. Conclusão: os sintomas no período menstrual são mais intensos quando comparados ao período pré-menstrual e podem afetar AVDs. O presente estudo destaca a importância de análises e cuidados em relação ao período menstrual, já que tem grande impacto nos fatores físicos, mentais e emocionais das mulheres sedentárias.

Objective: to establish the differences in physical and mental symptoms in menstrual and premenstrual periods in sedentary women. Methods: cross-sectional study, through questionnaire, answered by 77 healthy women, aged 18 to 35 years, sedentary and who did not use contraceptives continuously. The questionnaire included questions about anthropometric data, physical and mental symptoms in menstrual and premenstrual periods. The Mann-Whitney test compared menstrual and premenstrual times. Results: in the menstrual period, on a numerical scale from 0 to 10 points, there were more complaints of pain (7/10), bad mood (7/10), discouragement (8/10), irritability (8/10), anxiety (7/10), crying (7/10), anger (9/10) and impact on ADLs (7/10). In the premenstrual period, there were complaints of headache (5/10), edema/water retention (6/10), bad mood (6/10), sadness (6/10), irritability (7/10), crying (7/10) and anger (6/10). When comparing the menstrual and premenstrual periods, the menstrual period had worse symptoms of dysmenorrhea (P<0.05), low back pain (P<0.05), pain in the lower limbs (P<0.05), difficulty concentrating (P<0.05), increased sleep (P<0.05) and discouragement (P<0.05). The volunteers reported 14 worse symptoms, with intensity equal to or greater than 7 in the menstrual period, and 9 symptoms with intensity equal to or greater than 7 in the premenstrual period. Conclusion: the symptoms in the menstrual period are more intense when compared to the pre-menstrual period and can affect the ADLs. This study highlights the importance of analysis and greater care in relation to the menstrual period, as it has a great impact on physical, mental and emotional factors in sedentary women.

Effect of COVID-19 on Menstruation: An Observational Study

Introduction: COVID-19 patients have been reported to have systemic complications. Analyzing its effect on the endocrine system is essential to ensure women’s reproductive health. Aim: This study aimed to determine the effect of COVID-19 disease on menstruation. Methods: It was a hospital-based cross-sectional study conducted from October 2021 to April 2022, using a validated questionnaire to collect the data. The study included females (15 to 49 years) who had confirmed COVID infection. Results: A total of 132 females participated in the study. For 29 (22%) patients presenting with menstrual cycle changes, most common change was prolonged cycle (14%). An increase in menstrual volume was reported by 12%, where as 35% of patients experienced more pain during menstruation. Menstrual irregularities were significantly higher in severe infection (p-value 0.04). Conclusion: There were transient changes in menstruation in COVID-19-infected patients, with a higher probability of menstruation abnormalities among severely infected patients.

Experimental pain thresholds and psychosocial features across menstrual cycle in myofascial orofacial pain compared to healthy individuals: cross-sectional study / Limiares de dor experimental e características psicossociais ao longo do ciclo menstrual na dor miofascial orofacial em comparação com indivíduos saudáveis: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: The hormonal impact on pain perception during the menstrual cycle is a major focus of study, and further elucidation in temporomandibular disorders (TMD) field is necessary. Thus, this cross-sectional study evaluated experimental pain thresholds, psychosocial features, and clinical pain report on TMD women across menstrual cycle versus healthy controls. METHODS: A total of 220 women's clinical files were screened, with 80 selected and divided into control group (healthy individuals, n=40) and TMD group (myofascial pain, n=40). Regarding the menstrual cycle phases, the files were divided into Pre-Luteal and Luteal. The Perceived Stress Scale (PSS), Pain Catastrophizing Scale (PCS), Mechanical Pain Threshold (MPT), Wind-up (WUR), Pressure Pain Threshold (PPT), Conditioned Pain Modulation (CPM) and Visual Analogue Scale (VAS) were analyzed at a 5% significance level, by Two-Way ANOVA test and post hoc Tukey test. RESULTS: PSS and PCS were significantly different between TMD and control group (p<0.001), regardless of menstrual cycle. Healthy individuals in the Luteal phase presented higher MPT values compared to the other phases (p<0.001). PPT showed significant difference across menstrual phases (p=0.022), but no differences in multiple comparisons. VAS values showed no difference between menstrual cycle phases (p=0.376). CONCLUSION: Finally, healthy individuals in the Luteal phase have higher MPT and PPT values on the orofacial region. Pain report in patients with TMD showed no difference throughout the menstrual cycle, showing that small alterations on experimental pain thresholds may not be clinically relevant. The presence of chronic pain seems to be more related to psychosocial features than hormonal fluctuations.

RESUMO JUSTIFICATIVA E OBJETIVOS: O impacto do ciclo menstrual na percepção da dor é um foco importante de estudo, sendo necessária uma maior elucidação na disfunção temporomandibular (DTM). Assim, este estudo transversal avaliou limiares de dor experimental, características psicossociais e relatos de dor em mulheres com DTM ao longo do ciclo menstrual, comparadas com controles saudáveis. MÉTODOS: 220 prontuários de mulheres foram analisados, sendo 80 selecionados para os grupos de controle (saudáveis, n=40) e DTM (dor miofascial, n=40). Nas fases do ciclo menstrual, as pacientes foram divididas nas categorias Pré-Luteal e Luteal. Os instrumentos Escala de Estresse Percebido (PSS), Escala de Pensamentos Catastróficos (PCS), Limiar de Dor Mecânica (MPT), Wind-up Ratio (WUR), Limiar de Dor à Pressão (PPT), Modulação Condicionada da Dor (CPM) e Escala analógica visual (EAV) foram analisados com nível de significância de 5%, pelos testes ANOVA de dois fatores e Tukey post hoc. RESULTADOS: As escalas PSS e PCS foram significativamente diferentes entre os grupos DTM e controle (p<0,001), independentemente do ciclo menstrual. Indivíduos saudáveis na fase luteal apresentaram MPT maior em comparação com outras fases (p,0,001). O PPT mostrou diferença significativa entre as fases menstruais (p=0,022), sem diferença nas comparações múltiplas. Os valores da EAV não apresentaram diferença entre as fases menstruais (p=376). CONCLUSÃO: Indivíduos saudáveis na fase luteal têm MPT e PPTl maior na região orofacial. Os relatos de dor em pacientes com DTM não mostraram diferença ao longo do ciclo menstrual, indicando que pequenas alterações nos limiares experimentais podem ser clinicamente relevantes. A presença de dor crônica parece estar mais relacionada com características psicossociais do que com flutuações hormonais.
