ABSTRACT

Abstract Some studies report the positive effect of organic residues from ant nests on soil properties and on the structure of the adjacent plant community in field experiments, but there is a gap about the effect on individual species. The purpose of the present study was to compare the soil nutrient content and the development of Turnera subulata Smith, an ornamental species, in the presence of the nest refuse (basically composed of fragments of grass leaves and the symbiotic fungus) produced by the leaf-cutting ant Acromyrmex balzani (Emery, 1890) or in control soil through a greenhouse pot experiment. The experiment was carried out with two treatments: control soil and soil with 25% of nest refuse. The plants were kept in 1L pots for 90 days. We evaluated the parameters: plant height, stem diameter, root length, number of leaves, dry weight of the root, dry and fresh aboveground biomass. Additionally, the relative chlorophyll content and leaf nutrients were used as nutritional parameters. As a result, plants that grew in the soil with nest refuse showed significant higher values of all parameters evaluated when compared to the control treatment (p < 0.001). We conclude that this biofertilizer contributed to the production of more vigorous plants, being able to act on the local dynamics of nutrients in the ecosystems where A. balzani occurs. As it is relatively abundant and easy to collect, the refuse of A. balzani has the potential to be used as an alternative substrate in the production of shortlife cycle plants.


Resumo Alguns estudos relatam o efeito positivo de resíduos orgânicos de formigueiros nas propriedades do solo e na estrutura da comunidade de plantas adjacentes em experimentos de campo, mas há uma lacuna sobre o efeito em espécies individuais. O objetivo do presente estudo foi comparar o desenvolvimento de Turnera subulata Smith, uma espécie ornamental, na presença do substrato de descarte (SD) de formigueiros produzido pela formiga cortadeira Acromyrmex balzani (Emery, 1890) por meio de experimento em casa de vegetação. O experimento foi conduzido com dois tratamentos: solo controle e solo com 25% de SD. As plantas foram mantidas em vasos de 1L por 90 dias. Foram avaliados os parâmetros: altura da planta, diâmetro do caule, comprimento da raiz, número de folhas, massa seca da raiz, biomassa seca e fresca da parte aérea. Além disso, o conteúdo relativo de clorofila e os nutrientes foliares foram usados como parâmetros fisiológicos. Como resultado, as plantas que cresceram no solo com SD apresentaram valores significativamente maiores de todos os parâmetros avaliados quando comparadas ao tratamento controle (p < 0.001). Concluímos que esse biofertilizante contribuiu para a produção de plantas mais vigorosas, podendo atuar na dinâmica local de nutrientes nos ecossistemas onde A. balzani ocorre. Além disso, por ser relativamente abundante e fácil de coletar, o SD de A. balzani tem potencial para ser utilizado como biofertilizante na produção de plantas de ciclo de vida curta.

ABSTRACT

Introduction Glyphosate is an herbicide used to eradicate illicit crops; however, its use is controversial due to different health problems associated with it. The present study aims to evaluate the effects of glyphosate on human sperm in vitro. Methods Twenty-two semen samples from healthy normozoospermic men were included; 11 semen samples were incubated with Panzer (INVESA S.A., Antiquia, Colombia) and 11 with Roundup (Monsanto Company, MO, USA). The changes in motility and viability were observed. Functional seminal parameters were evaluated as well. Results The samples exposed to glyphosate showed less motility and viability; a decrease in the potential of the mitochondrial membrane was observed, and an increase in the lipoperoxidation of the membrane was evidenced. Conclusion Based on the present results, we concluded that

ABSTRACT

The objective of this study was to compare the reproductive efficiency of dairy buffaloes undergoing fixed-time artificial insemination (FTAI) protocols based on progesterone/estrogen (P4/E2) and eCG during unfavorable breeding season using cooled (CS) and frozen semen (FS). A total of 446 buffaloes (> 40 days postpartum) were randomly distributed into four blocks (years): B1-2014 (n = 143), B2-2015 (n = 34), B3-2016 (n = 90), and B4-2017 (n = 179). Each block was subdivided into two (AI with CS and FS using the same ejaculate of each bull). Thus, the block subdivision was as follows: B1 (CS = 71 and FS = 72); B2 (CS = 18 and FS = 16); B3 (CS = 47 and FS = 43); and B4 (CS = 90 and FS = 89). The ejaculates of eight Murrah bulls collected using an artificial vagina were divided into two aliquots: one aliquot was diluted in Botu-Bov® commercial extender and cooled (BB-CS), and the other was diluted in the same extender and frozen (BB-FS). BB-CS aliquots were cooled at 5 °C/24 h using a refrigerator. BB-FS group aliquots were also cooled, and after equilibrating at 5 °C for 4 h, were placed in a 21-L Styrofoam box, 5 cm above the surface of liquid nitrogen. In the afternoon (A) on D0 (2:00 p.m.) the animals received EB 2.0 mg IM (Estrogin®) and an ear implant (CRESTAR® 3.0 mg P4). At D9 (A), the implant was removed, and the animals received eCG 400 IU IM (Folligon® 5000) + Cloprostenol PGF2α 0.530 mg IM (Sincrocio®). At D10 (A), the animals received EB 1.0 mg IM (Estrogin®), and at D12 (8:00 a.m.), AI was performed. At D42, pregnancy was diagnosed via ultrasonography. Total CRs were 48.2% CS and 34.6% FS for years 2014 to 2017, with a significant difference of 13.7% (P<0.05). In conclusion, cooled semen resulted in higher CR than frozen semen in dairy buffaloes under the P4/E2 and eCG FTAI during the unfavorable reproductive season.(AU)


O objetivo deste estudo foi comparar a eficiência reprodutiva de búfalas leiteiras submetidas a protocolos de inseminação artificial em tempo fixo (IATF) à base de progesterona/estrogênio (P4/E2) e eCG, durante a estação reprodutiva desfavorável, usando-se sêmen resfriado (SR) e congelado (SC) Um total de 446 búfalas (> 40 dias após o parto) foi distribuído aleatoriamente em quatro blocos (anos): B1-2014 (n = 143), B2-2015 (n = 34), B3-2016 (n = 90) e B4-2017 (n = 179). Cada bloco foi subdividido em dois (IA com SR e SC utilizando-se a mesma ejaculação de cada touro). Assim, a subdivisão do bloco foi a seguinte: B1 (SR = 71 e SC = 72); B2 (SR = 18 e SC = 16); B3 (SR = 47 e SC = 43); e B4 (SR = 90 e SC = 89). Os ejaculados de oito touros Murrah coletados com vagina artificial foram divididos em duas alíquotas: uma alíquota diluída em diluente comercial Botu-Bov® e resfriada (BB-SR), e a outra diluída no mesmo diluente e congelada (BB-SC). As alíquotas de BB-SR foram resfriados a 5°C/24h usando-se um refrigerador. As alíquotas do grupo BB-SC também foram resfriadas e, após equilíbrio a 5°C por 4h, foram colocadas em uma caixa de isopor de 21L, 5 cm acima da superfície do nitrogênio líquido. À tarde (A), no D0 (14h), os animais receberam BE 2,0 mg IM (Estrogin®) e um implante auricular (Crestar® 3,0 mg P4). No D9 (A), o implante foi retirado e os animais receberam eCG 400 UI IM (Folligon® 5000) + cloprostenol PGF2α 0,530 mg IM (Sincrocio®). No D10 (A), os animais receberam BE 1,0mg IM (Estrogin®), e, no D12 (8h da manhã), foram realizadas as IAs. No D42, a gestação foi diagnosticada por ultrassonografia. As taxas de concepção (TC) totais foram 48,2% SR e 34,6% SC para os anos de 2014 a 2017, com uma diferença significativa de 13,7% (P<0,05). Em conclusão, o sêmen resfriado resultou em maior TC do que o sêmen congelado em bubalinos leiteiros sob P4/E2 e eCG FTAI durante a estação reprodutiva desfavorável.(AU)

ABSTRACT

Hemorragia pós-parto é a maior causa de histerectomia periparto. Esta revisão descreve e ilustra as técnicas de ligaduras vasculares utilizadas no tratamento cirúrgico da hemorragia pós-parto. São apresentados os detalhes técnicos da ligadura das artérias uterinas, da ligadura das conexões útero-ovarianas, da ligadura tríplice de Tsirulnikov, das ligaduras sequenciais de AbdRabbo e de Morel e da ligadura das artérias ilíacas internas. Também são revistos os fatores que dificultam o sucesso dessas técnicas. As ligaduras vasculares são estratégias eficientes para o controle hemorrágico durante cesarianas e devem integrar o conjunto de técnicas que preservam o útero no tratamento da hemorragia pós-parto.(AU)


Postpartum hemorrhage is the major cause of peripartum hysterectomy. This review describes and illustrates the techniques of vascular ligations used in the surgical treatment of postpartum hemorrhage. The technical details of the uterine arteries ligation, of the ligation of the utero-ovarian connections, of the Tsirulnikov triple ligation, of the AbdRabbo and Morel sequential ligations and of the internal iliac arteries ligation are presented. The factors that hinder the success of these techniques also are reviewed. Vascular ligations are efficient strategies for hemorrhagic control during cesarean sections and should integrate the set of techniques that preserve the uterus in the treatment of postpartum hemorrhage.(AU)

ABSTRACT

The aim of this work was to compare results of breeding soundness examination (BSE) of Nellore bulls (n=1257) according to evaluation criteria from two different classification tables (traditional-Table1 used since 1997 and an updated-Table2-proposed in 2020). Data were separated into 3 categories: questionable animals in Table1 and Table2 (Q1Q2), animals approved in Table1 and questionable in Table2 (A1Q2) and animals approved in Table1 and Table2 (A1A2). BSE parameters were submitted to ANOVA (P<005), according to age groups. Higher (P<0.0001) scrotal perimeter (PE) were observed in A1A2 category (18-24m=33.4±2.4cm; 24-36m=34.5±2.2cm; 36-48m=36.6±1.7cm; >48m=38.6±1.7cm) compared to A1Q2 (18-24m=29.05±0.98cm; 24-36m=30.3±0.6cm; 36-48m=32.9±1.0cm; >48m=34.8±1.0cm) and to Q1Q2 (24-36m=26.8±2.0cm; 36-48m=30.0±0.1cm; >48m=31.3±1.1cm), for all age groups. At the age of 36-48months (Q1Q2=2.7±0.3; A1Q2=3.2±0.3; A1A2=3.3±0.6) and >48months (Q1Q2=3.0±0.4; A1Q2=3.3±0.5; A1A2=3.4±0.5), animals with better andrological classifications presented higher (P<0.05) body condition score (BCS). Additionally, at age >48m, higher sperm Motility (P=0.0250) and Vigor (P=0.0335) were observed in animals A1Q2 (Mot=55.5±14.7%; V=3.21±0.82) and A1A2 (Mot=55.8±12.2%; V=3.23±0.81) compared to Q1Q2 (Mot=50.2±17.4%; V=2.77±0.82). It was concluded that bulls approved using strict selection criteria demonstrated higher PE and BCS, regardless of the age. The utilization of updated classification tables is highly recommended for further reproductive potential development of Nellore bulls in the field.(AU)


O objetivo deste estudo foi comparar os resultados obtidos no exame andrológico a campo de touros Nelore (n=1257) de acordo com os critérios de avaliação de duas tabelas de classificação (uma tabela tradicional - tabela 1 - proposta em 1997 e uma nova tabela atualizada - tabela 2 - proposta em 2020). Os dados foram separados em três categorias: animais questionáveis nas tabelas 1 e 2 (Q1Q2), animais aprovados na tabela 1 e questionáveis na tabela 2 (A1Q2) e animais aprovados nas tabelas 1 e 2 (A1A2). Os parâmetros foram submetidos à análise de variância (P<0,05), por faixa etária. Observou-se maior (P<0,0001) PE no grupo A1A2 (18-24m=33,4±2,4cm; 24-36m=34,5±2,2cm; 36-48m=36,6±1,7cm; >48m=38,6±1,7cm) em comparação ao grupo A1Q2 (18-24m=29,05±0,98cm; 24-36m=30,3±0,6cm; 36-48m=32,9±1,0cm; >48m=34,8±1,0cm) e este maior (P<0,0001) que Q1Q2 (24-36m=26,8±2,0cm; 36-48m=30,0±0,1cm; >48m=31,3±1,1cm) em todas as idades. Nas faixas etárias 36-48m (Q1Q2=2,7±0,3; A1Q2=3,2±0,3; A1A2=3,3±0,6) e >48m (Q1Q2=3,0±0,4;A1Q2=3,3±0,5; A1A2=3,4±0,5), animais com melhor classificação andrológica apresentaram melhor (P<0,05) escore de condição corporal (ECC). Adicionalmente, na idade >48m, maiores motilidade (P=0,0250) e vigor (P=0,0335) foram observados nos animais A1Q2 (Mot=55,5±14,7%; V=3,21±0,82) e A1A2 (Mot=55,8±12,2%; V=3,23±0,81) comparados aos animais Q1Q2 (Mot=50,2±17,4%; V=2,77±0,82). Concluiu-se que touros aprovados na tabela com critérios mais rigorosos de classificação (tabela 2) apresentaram maior PE e ECC, independentemente da idade. Assim, a utilização de tabelas classificatórias atualizadas é fundamental para maior desenvolvimento do potencial reprodutivo de touros Nelore a campo.(AU)

ABSTRACT

Resumen: Introducción: en los últimos años se viene presentando un fenómeno de disminución en las defunciones vinculadas al embarazo ectópico gracias a los avances en el diagnóstico precoz, lo que a su vez abrió las puertas al tratamiento médico con metotrexate en pacientes seleccionadas. El objetivo del presente trabajo es reportar la experiencia del tratamiento con metotrexate en el departamento de Paysandú y determinar secundariamente la satisfacción de las usuarias frente a éste y su fertilidad posterior. Método: se presenta un estudio retrospectivo, observacional, de los embarazos ectópicos tubarios tratados con metotrexate en Paysandú, durante el período del 1º de enero de 2014 al 31 de diciembre de 2017, comprendiendo cuatro años. Se consideró fracaso del tratamiento médico cuando fue necesario tratamiento quirúrgico y se definió como fertilidad futura al tiempo que transcurrió hasta lograr una gestación intrauterina espontánea. Resultados: se registraron 67 embarazos ectópicos en cuatro años, 13 recibieron metotrexate intramuscular con un porcentaje de éxito de 69,2%. Se determinó una fertilidad posterior de 25%. Conclusiones: el uso de metotrexate en el embarazo ectópico se practica en Paysandú desde hace casi una década con buenos resultados y una buena aceptación por parte de las usuarias.


Summary: Introduction : In recent years there has been a decrease in deaths related to ectopic pregnancy, thanks to progress made in early diagnosis, which in turn allowed for medical treatment with methotrexate in selected patients. The study's first objective is to report the experience of methotrexate treatment in the Department of Paysandú and its secondary objective is to determine users' satisfaction towards this treatment and find about their subsequent fertility. Method: a retrospective, observational study is presented of tubal ectopic pregnancies treated with methotrexate in Paysandú, from January 1, 2014 to December 31, 2017, during a 4-year period. Failure of medical treatment was defined as the cases requiring surgical treatment and subsequent fertility was defined as the time it took to achieve a spontaneous intrauterine gestation. Results: 67 ectopic pregnancies were recorded in four years, 13 of which received intramuscular methotrexate with a success rate of 69.2%. Subsequent fertility was found to be 25%. Conclusions: methotrexate has been used to treat ectopic pregnancies in Paysandú for almost a decade, with good results and acceptable rates of user satisfaction.


Resumo: Introdução: nos últimos anos, observou-se uma diminuição dos óbitos relacionados à gravidez ectópica, graças aos avanços no diagnóstico precoce, que por sua vez abriram as portas para o tratamento médico com metotrexato em pacientes selecionadas. Objetivo: o objetivo deste trabalho é relatar a experiência do tratamento com metotrexato no Departamento de Paysandú e determinar secundariamente a satisfação das usuárias com o mesmo e sua consequente fertilidade. Métodos: apresenta-se um estudo retrospectivo e observacional de gestações ectópicas tubárias tratadas com metotrexato em Paysandú, durante o período de 1º de janeiro de 2014 a 31 de dezembro de 2017. Considerou-se como falha do tratamento médico quando o tratamento cirúrgico foi necessário e definiu-se fertilidade futura como o tempo decorrido até a obtenção de uma gravidez intrauterina espontânea. Resultados: foram registradas 67 gestações ectópicas em quatro anos, 13 receberam metotrexato intramuscular com taxa de sucesso de 69,2%. Uma fertilidade subsequente de 25% foi determinada. Conclusões: o uso do metotrexato na gravidez ectópica é praticado em Paysandú há quase uma década com bons resultados e boa aceitação pelas usuárias.

ABSTRACT

Introducción: debido al retraso de la maternidad, es probable que las mujeres jóvenes con diagnóstico de cáncer de mama (CM) no hayan completado su proyecto de maternidad al momento del diagnóstico y estén interesadas en su fertilidad futura y podrían enfrentarse también a un cáncer de mama asociado al embarazo. El objetivo del trabajo fue analizar la práctica actual, de los miembros de la Sociedad Argentina de Mastología (SAM), sobre preservación de la fertilidad y embarazo. Material y método: se realizó una encuesta por correo electrónico. Respondieron 213 miembros. Resultados: la frecuencia con la que abordan el impacto del tratamiento oncológico en la fertilidad de las pacientes jóvenes y las derivan, fue "siempre" y "casi siempre" en 84,4% y 74,5% respectivamente. El 73,6% afirmó que el embarazo luego del CM no empeora el pronóstico. El 70,1% consideró seguro el uso de radiocoloides para identificar el ganglio centinela durante el embarazo. Encontramos una diferencia significativa en las respuestas de los profesionales pertenecientes a una UM. Conclusiones: el nivel de conocimiento es similar al de otras encuestas. La pertenencia a una unidad de mastología se asoció a un mejor nivel de actualización. Es necesario seguir trabajando en la capacitación de los profesionales.


Introduction: due to delayed motherhood, Young women diagnosed with breast cancer (BC) are likely to have not competed their maternity Project at the time of diagnosis, are interested in future fertility and may also face pregnancy-associated breast cancer. The aim of this study was to analyze the current practice of the Argentine Society of Mastology (SAM) members, on fertility preservation and pregnancy. Material and method: an email survery was conducted 231 members responded. Results: the frequency with which respondentes discuss the impact of cancer treatment of fertility among Young patients and referral was "always" and "almost always", 84.4% and 74.5% respectively. 73.6% considered pregnancy after BC does not worsen the prognosis. 70.1% used radiocoloids to identify sentinel node during pregnancy. We found a significant difference in the responses of professionals belonging to a Breast Unit. Conclusions: the level of knowledge is similar to that of other surverys. Working within a Breast Unit was associated with a better level of knowledge. Further work is needed in the training of professionals.

ABSTRACT

Abstract We report a case of ultrasound-guided ex vivo oocyte retrieval for fertility preservation in a woman with bilateral borderline ovarian tumor, for whom conventional transvaginal oocyte retrieval was deemed unsafe because of the increased risk of malignant cell spillage. Ovarian stimulation with gonadotropins was performed. Surgery was scheduled according to the ovarian response to exogenous gonadotropic stimulation; oophorectomized specimens were obtained by laparoscopy, and oocyte retrieval was performed ~ 37 hours after the ovulatory trigger. The sum of 20 ovarian follicles were aspirated, and 16 oocytes were obtained.We performed vitrification of 12 metaphase II oocytes and 3 oocytes matured in vitro. Our result emphasizes the viability of ex vivo mature oocyte retrieval after controlled ovarian stimulation for those with high risk of malignant dissemination by conventional approach.


Resumo Relatamos um caso de obtenção ex vivo de óvulos, guiada por ultrassonografia, para preservação da fertilidade em uma mulher com tumor ovariano borderline bilateral, para quem a recuperação transvaginal convencional foi considerada insegura, devido ao aumento do risco de disseminação de célulasmalignas. Foi realizada estimulação ovariana com gonadotrofinas. A cirurgia foi agendada de acordo com a resposta ovariana à estimulação gonadotrófica exógena; após ooforectomia por laparoscopia, ~ 37 horas após a maturação folicular, procedeu-se à recuperação extracorpórea de oócitos. Umtotal de 20 folículos ovarianos foi aspirado e 16 complexos cumulus foramobtidos, resultando na vitrificação de 12 oócitos maduros e de 3 oócitos imaturos amadurecidos in vitro.

ABSTRACT

ABSTRACT Purpose The spleen is relevant in blood purification, hematopoiesis, metabolism, and immune response to antigens, in addition to the storage and control on the release of metals and amino acids. Its functions concerning reproduction characteristics are still unknown. The objective was to study the influence of splenectomies on reproduction. Methods This study analyzed 25 mice couples, distributed into five groups: group 1 - control, no surgery: group 2 - control, submitted to laparotomy and laparorrhaphy only; group 3 - splenectomy in male mice; group 4 - splenectomy in female mice; group 5 - splenectomy in male and female mice. The animals were studied as regards the number of gestations and offspring generated in each gestation. Results A decrease in both the number of gestations and the number of offspring was verified in the male mice that had received a splenectomy when coupled with normal female mice. It is important to emphasize lower reproduction level when paired asplenic males with normal females, otherwise, the couples in which both mice had been splenectomized did not present change in the reproduction pattern. Conclusions A reduction in the number of pregnancies and litters occurs in mice couples when the male mice were previously splenectomized.

ABSTRACT

Objective To study the effect of metabolic syndrome on the fertility and reproduction in model animals. Methods The model of"high fat diet for spontaneously hypertensive rats(SHR)"was adopted to construct the model of metabolic syndrome in rats. The metabolic syndrome model rats were used to mate with male and female 1 : 1 cage, and the mating cycle was 2 weeks. Results After the SHR rats were fed a high-fat diet for 10 weeks, 16 males and 15 females met the screening criteria for metabolic syndrome, with the modeling rates of 40% and 37.5%, respectively. In addition to the abnormal metabolism-related indicators(such as blood glucose, blood lipid and blood pressure), the male rats with metabolic syndrome mainly had decreased sperm motility(P < 0.05), increased sperm malformation rate(P < 0.01), and decreased mating rate(P < 0.05). In addition to abnormal metabolism-related indicators, the conception rate and the live fetal rate of the female rats with metabolic syndrome were slightly lower than that of the control group; however, there was no statistical difference. The mean birth weight of the litter was significantly lower than that of the control group(P < 0.05). Conclusion According to the whole process from mating to natural production, metabolic syndrome is determined to have a significant effect on the fertility and reproductive ability of rats.

ABSTRACT

Objective To explore the impact of the two-child policy on the fertility level of residents in Yangpu District. Methods Birth registry data were collected from the residents of Yangpu District in Shanghai during January 2015 to December 2018 for the analysis of birth characteristics and its variation after the two-child policy implementation. Results The total fertility rate was higher than 1 only in 2016 that was 1.04, whereas it was about 0.8 in other three years. The number of the second child increased which was inspired by the policy. However, the increment in the number of second child was far less than the decrease in the first child. From 2015 through 2018, the proportion of second children in the total births with local household registration accounted for 18.84%, 20.03%, 26.29% and 24.35%, respectively. From January 2015 to August 2016, the proportion of second children was on the rise slowly, in which the annual percent change(APC)value was 0.34%(P > 0.05). From September 2016 to May 2017, the proportion of second children had shown an obvious increase, and the APC value was 3.97%(P < 0.05). From June 2017 to December 2018, the proportion of second children was on a downward trend, in which the APC value was -0.97%(P < 0.05). Conclusion Favorable fertility policy may not reverse the fertility level in Yangpu District, which remains at a very low level.

ABSTRACT

With the technology development of cancer treatment, the survival rate of patients with cancer has been significantly improved. However, chemotherapy and radiation therapy may lead to premature ovarian failure and infertility in young women with cancer. Cryopreserved ovarian tissue auto-transplantation is an effective method to preserve fertility of such female patients. At present, the biggest challenge of this technique is mass loss of follicles after transplantation. In this article, the influencing factors and improvement methods of survival of cryopreserved ovarian tissue auto-transplantation were reviewed.

ABSTRACT

Objective:To analyze the clinical efficacy and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH-a) based fertility-sparing re-treatment in women with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) who failed with oral progestin therapy.Methods:Forty cases with EC or AEH who failed to respond to oral progestin were included from January 2012 to December 2020 at Peking Union Medical College Hospital. Combination of GnRH-a with levonorgestrel-releasing intrauterine system (group GLI: a subcutaneous injection of GnRH-a every 4 weeks and LNG-IUS insertion constantly) or the combination of GnRH-a with aromatase inhibitor (group GAI: a subcutaneous injection of GnRH-a every 4 weeks and oral letrozole 2.5 mg, daily) were used for these patients. Histological evaluation were performed at the end of each course (every 3-4 months) by hysteroscopy and curettage. After the complete remission (CR), all patients were followed up regularly.Results:(1) Clinical characteristics:among the 40 patients with EC or AEH, the median age at diagnosis was 31 years (range: 22-40 years) and the median body mass index was 24.7 kg/m 2 (range: 18.9-39.5 kg/m 2). (2) Efficacy of fertility-sparing re-treatment: 37 (92%, 37/40) patients achieved CR, 6 (6/7) in AEH and 31 (94%, 31/33) in EC patients. The CR rate was 93% (26/28) and 11/12 in group GLI and GAI, respectively. The median time to CR was 5 months (range: 3-12 months). At the end of the first therapy course, the CR rates in AEH and EC were 5/7 and 42% (14/33), at the second course, the CR rates were 6/7 and 82% (27/33), respectively. (3) Recurrence: after 25 months of median follow-up duration (range: 10-75 months), 8 (22%, 8/37) women developed recurrence, 1/6 in AEH and 7 (23%, 7/31) in EC patients, with the median recurrence time of 18 months (range: 9-26 months). Among them, two cases who had completed childbirth chose to receive hysterectomy directly. Six patients met the criteria of fertility-preserving therapy and received conservative treatment again and 5 (5/6) of them achieved CR. (4) Pregnancy: of the 37 patients with CR, 33 desired to conceive. Ten women attempted to get pregnancy spontaneously and 23 cases with assisted reproductive technology. Fourteen (42%, 14/33) patients became pregnant, including 9 (27%, 9/33) live births, 3 (9%, 3/33) missed abortions, and 2 (6%, 2/33) miscarriages at the second trimester. Conclusions:GnRH-a based fertility-sparing re-treatment in AEH or EC patients who failed with oral progestin therapy achieved good treatment effect and reproductive outcomes. It is an encouraging alternative regime for patients who failed with oral progestin therapy.

ABSTRACT

Objective:To study the status and influencing factors of fertility anxiety in breast cancer patients, and analyze the relationship between social support and fertility anxiety and the mediating role of psychological resilience.Methods:From January to May, 2020, 120 young breast cancer patients were investigated by the Cancer Reproductive Anxiety Scale, the Perceived Social Support Scale, and the Self-Resilience Scale and analyze the relationship of psychological resilience, social support with fertility anxiety, as well as the mediating role of psychological resilience among them.Results:Social support, psychological resilience were significantly negatively related to fertility anxiety and all dimensions ( r value was -0.428 to -0.126, P<0.05).Social support had negative predicting effect on fertility anxiety ( β value was -0.386, P<0.001). Psychological resilience of breast cancer patients had a partial mediating role between social support and fertility anxiety, accounting for the 35.8% of the total effect. Conclusions:Psychological resilience plays an important role in alleviating the fertility anxiety of breast cancer patients. Enhancing the psychological elasticity of breast cancer patients is an effective way to alleviate the anxiety of breast cancer patients.

ABSTRACT

Serum amyloid P component (SAP) is present in seminal plasma, on spermatozoa, and in different tissues of the male reproductive tract, but its function is not known. The aims of this study were to determine if the concentration of SAP in seminal plasma is associated with commonly assessed semen parameters and to investigate if SAP could be a new, indirect biomarker for these parameters. In a cross-sectional study of 203 young volunteers, the concentration of SAP in seminal plasma was measured with a in-house developed enzyme-linked immunosorbent assay. Scatter plots, Pearson's correlation coefficients (r), and linear regression models were produced, and SAP showed a statistically significant correlation with sperm concentration (r = 0.75), sperm number (r = 0.68), semen volume (r = -0.19), progressive sperm motility (r = 0.24), and sperm immotility (r = -0.20). When the study group was dichotomized, SAP could be used to discriminate samples with a sperm concentration < or ≥5 × 10

ABSTRACT

Fluted pumpkin (FP; Telfairia occidentalis) is an edible vegetable, grown in West Africa, that is used in traditional medicine for its regulatory effects on the male gonads. Scientific articles concerning the effects of FP were identified by searching PubMed, PubChem, Scopus, Springer, ResearchGate, Google Scholar and Web of Science; this literature was to better understand the effects of FP seed (FPS) and leaf (FPL) extracts on the testes. Data showed that in experimental animals extracts of FPL and FPS at 1/100 of the lethal dose promoted testis regeneration and improved testosterone concentration and sperm quality, while at higher doses they had antifertility effects. Several extracts of FPS and FPL, including ethanol, aqueous, methanol and hydroethanolic, had protective effects on the testes of study animals at lower doses (≥ 50 mg/kg body weight), but at higher doses (≥ 200 mg/kg body weight) they inhibited hormone synthesis, sperm quality and histomorphological structure, under both normal and disease conditions. The posttreatment effects of FPS on the gonads were reversible in young mature rats and FPS had slight systemic toxic effects. Although, there are inconsistencies in some of the published results, the current evidence suggests that FPS and FPL have both profertility and reversible antifertility effects in experimental animals.
