Interaction of the reagents and the substrate stainless steel was analyzed during the deposition of tantalum coatings by reduction of tantalum bromide with cadmium. It was found that at deposition temperatures above 1000 K, the iron and chromium contents in stainless steel will reduce tantalum pentabromide passing into the gas phase in the form of bromides. As a result, not only tantalum bromide is reduced on the substrate, but also iron bromide which in the initial stages of deposition leads to the formation of iron containing sublayer in the coating. An increase in the contact surface of stainless steel interacting with reagents leads to an increase in the content of iron bromide, in which case a coating is formed from a Ta + Fe2Ta mixture. In addition, chromium bromide is formed on the substrate, which is removed along with the rest of the reaction products. It causes chromium depletion in the surface layers of steel.

The method of universal characteristics of an electric arc is described as a mathematical basis for the heat exchange model of an electric arc in the processes of electric arc heating in electrical engineering. Application of this method for calculation of the temperature characteristics of an arc column compressed by the walls of the discharge channel in the stabilization zone of a laminar plasma torch operating in air is considered. An example of the temperature profile calculation of a wall-stabilized arc for a plasma generator with a discharge channel diameter of 5 mm operating in air at an arc current of 60 A is presented. Calculated results are compared with the results of experimental studies of this plasma generator.

The low-velosity impact properties and failure mechanisms of ultra-high molecular weight polyethylene (UHMWPE) fiber (Dyneema®SK-75) and a composite material (CM) based on it with the rigid and flexible matrices were investigated by the “Impact Break” (IB) method. A fundamental difference in deformation behavior and failure mechanisms upon impact on the UHMWPE-fiber and on the CM based on this fiber has been investigated experimentally. It is shown that impact has a little effect on the properties of UHMWPE-fiber, since it is an isotropic material. It has been established that upon impact, the properties of a fiber without a matrix were significantly higher than the properties of CM based on it. Impact action stimulates the interaction between CM components (fibers and matrix). Mechanism of stepwise deformation of anisotropic CM is occurred, which begins from the first moment of impact and ends with the destruction of the CM. A “stairway of deformation” behavior is observed in anisotropic materials. Stepwise deformation is the main form of deformation and the basic mechanism of failure of anisotropic composite materials upon impact.

It has been established that the time to establish the critical contact angle of wetting of the surface of a pressed sample made of polycrystalline quartz powder with various liquids is mainly determined by the viscosity of the liquid. It is shown that in order to determine the critical contact angle of wetting of powder materials, it is necessary to fix the time moment at which the diameter of the base of a liquid drop on the surface of a powder sample has a maximum value.

Published: February 2021

Objective: To evaluate the effectiveness of uterine artery embolization (UAE) with gelatin sponge particles for symptomatic focal and diffuse adenomyosis. Materials and Methods: This was a retrospective study conducted between January 2014 and December 2019. All women underwent UAE for symptomatic adenomyosis without leiomyomas. Gelatin sponge particles were used in all cases. Patients were assessed for effectiveness of symptom control, changes in uterine volume, and degree of tumor necrosis on magnetic resonance (MR) imaging. Results: One hundred and sixty-three patients underwent UAE. There were statistically significant differences in bleeding score, pain score, and uterine volume at three months after UAE (P < 0.001, P < 0.001, and P < 0.001, respectively). Complete tumor necrosis occurred in 66.9% of cases after UAE. Proportion of complete necrosis were significantly different in cases with focal adenomyosis compared with diffuse adenomyosis (P = 0.023). Symptom recurrence occurred in 20.6% of cases at 12-month follow-up. Focal adenomyosis patients with complete necrosis had no recurrent menorrhagia and dysmenorrhea. No major complications were observed. Conclusions: UAE using gelatin sponge particles is an effective and safe treatment for symptomatic adenomyosis. Patients with focal adenomyosis with complete necrosis after UAE had no symptom recurrence at midterm follow-up.

Published: February 2021

Purpose: Evaluation of the effect of platelet-rich plasma (PRP) containing platelet-derived growth factor on in vitro fertilization (IVF) failure patients. Methods: In this clinical trial, 80 eligible patients (infertile women with at least two IVF failures) were randomly assigned into two groups, including patients who received an intrauterine infusion of PRP (n: 40) and controls (n: 40). Before PRP therapy, standard hormone replacement therapy was performed for all patients to endometrial thickness preparation. After sonographic assessment of endometrium, PRP was injected into all patients’ endometrium whether they had an appropriate endometrial thickness or not. Then, the embryo transferring was done through IVF. Eventually, the consequences of fertility, embryo implantation, and pregnancy were evaluated. Data analysis was performed using SPSS version 22. Results: The rate of successful IVF [6 (15%)], pregnancy rate [5 (12.5%)], and live birth [5 (12.5%)] were relatively higher in patients undergoing PRP therapy compared with controls [2 (5%), 1 (2.5%) and 0, respectively]. However, their statistical difference was not significant between the two groups (P > 0.05). Conclusion: Our findings suggest that endometrial injection of platelet-rich plasma for IVF failure patients did not significantly improve the IVF process, pregnancy, and live birth rates.

Authors: Pongsatha Saipin , Tongsong Theera
Published: February 2021

Objective: To compare the efficacy and adverse effects of 400 mcg misoprostol for second trimester pregnancy termination via the intravaginal or sublingual route. Methods: In this study, 170 women at GA 14-28 weeks underwent termination of pregnancy. They were randomized to receive either intravaginal or sublingual 400 mcg misoprostol at 6 hour intervals until fetal expulsion occurred or within 48 hours after the initiation of the first dose of misoprostol. The primary outcomes were median abortion time and percentage of failure. The secondary outcomes included rates of maternal adverse effects, oxytocin use and analgesia requirement. Results: Intravaginal misoprostol demonstrates significantly greater efficacy for pregnancy termination compared to sublingual misoprostol at the same dosage. The median time to abortion was 16.66 hours and 22.88 hours in the intravaginal group and sublingual group respectively. Maternal adverse effects, specifically rate of chill and diarrhea, were statistically higher in the sublingual group. Conclusion: Intravaginal misoprostol was superior to sublingual misoprostol in terms of shorter abortion time and fewer adverse effects. In addition the rate of oxytocin use was found to be higher in the sublingual group. In conclusion misoprostol via the intravaginal route should be considered for second trimester pregnancy termination rather than the sublingual route due to greater efficacy and fewer adverse maternal effects.
Adenomyosis - Is a new treatment solution available?
Authors: Wong Wu Shun Felix , Zhu Xiao-Gang , Xue Min
Published: February 2021

Adenomyosis is increasingly common up to 20% to 30% of reproductive-aged women who present with menorrhagia, dysmenorrhoea, infertility, and related pregnancy complications. It is often diagnosed by the clinical symptoms and ultrasound examinations. MRI, if available, will give a more detailed confirmation of adenomyosis. There are many medical treatments available for adenomyosis, e.g., oral contraceptives, LNG-IUS, GnRH-a, and progestin, while surgery is often either conservative adenomyomectomy or hysterectomy. All these treatments either impact on the fertility of these patients or not readily accepted by them because of the invasiveness of the surgery and side effects of medication. High Intensity Focused Ultrasound (HIFU) ablation treatment discussed in the paper offers an alternative non-invasive treatment for adenomyosis. The early results of HIFU ablation are satisfactory and well accepted by patients. However, long term follows up, with a combination of medical treatments after HIFU ablation, may offer a new treatment solution for adenomyosis.

Published: February 2021

Neck pain during pregnancy has negative effects on the quality of a woman’s life. The goal of this study was to determine the efficacy of kinesio-tape application on neck pain and functional activity during pregnancy. Thirty primigravid women who suffered from mechanical neck pain during the second and third trimester of pregnancy were recruited. They were randomly assigned to two groups: one received general antenatal advice about good posture in addition to kinesio taping for 4 weeks; the other received only general antenatal advice about good posture. Pain was assessed with the Visual Analogue Scale (VAS) and Neck Disability Index scale (NDI) at the start of the study and after 4 weeks of treatment. After 4 weeks, both groups showed improvement, but the group that received advice and kinesiology taping showed significantly less pain (VAS) than did the control group, but no differences in NDI scores. Kinesiology taping and antenatal advice are more effective for treatment of neck pain during pregnancy than is antenatal advice alone.

The current role of lymphadenectomy in early-stage high-risk endometrioid endometrial cancer is to guide further adjuvant treatment according to lymph node status. Whether the procedure has any therapeutic role remains controversial. In this study we aimed to investigate the outcome of current practices by performing a population-based retrospective cohort analysis using the US population-derived freely accessible public Surveillance, Epidemiology and End Results program (SEER) database. SEER data from patients with endometrial cancer treated between 2004 and 2012 were accessed online on March 1, 2016. Kaplan-Meier estimators were used to describe the survival distribution and the log-rank (Mantel-Cox) test was used to perform overall and pairwise comparisons of the survival distributions. The cohort included 47,463 patients, 10,288 of whom fulfilled high-risk criteria. A higher lymph node yield count was associated with better overall survival, although the removal of more than 40 lymph nodes did not confer any further survival benefit. The application of pelvic irradiation without lymph node status confirmation did not provide a survival benefit. From this analysis, no evidence of a survival benefit associated with lymphadenectomy was found. However, the current role lymphadenectomy as a staging and guiding tool for further adjuvant treatment was supported. Well-designed prospective randomized trials are required to conclusively determine the prognostic and therapeutic value of lymphadenectomy in patients with high-risk endometrioid endometrial cancers.

Total laparoscopic hysterectomy (TLH) is one of the techniques feasible for the treatment of myoma. Our department has performed more than 1,000 laparoscopic hysterectomies since 2014. In our department, these surgeries are performed by a supervising doctor, operator, and a first assistant who is often insufficiently experienced. There are several types of injuries that can occur during laparoscopic surgery; however, cases in which the vaginal pipe is inserted incorrectly are very rare. Here, we report the case of a 47-year-old nulliparous woman who experienced a rectal injury caused by the misinsertion of a vaginal pipe into the rectum. Seven years prior, she had undergone a myomectomy for leiomyomas. Later, she developed recurrent leiomyomas and worsening hypermenorrhea; therefore, she underwent a total laparoscopic hysterectomy. During the operation, the first assistant usually inserts a vaginal pipe into the vagina when the vaginal wall is cut. In this case, when the vaginal wall was cut, the vaginal pipe was inserted into the rectum, and the rectal wall was incised, allowing communication between the rectum and vagina. The rectum was repaired with the support of a gastroenterological surgeon, and the operation was completed laparoscopically. On the 7th postoperative day, an enema was performed to confirm that no leaks were present, and feeding was restarted. The patient was discharged home on the 17th postoperative day. The current case highlights the necessity of surgeons to be aware of various factors when performing this procedure to prevent complications, even those that are rare.

Congenital uterine anomalies result from the abnormal differentiation, migration, fusion and canalization of Mullerian ducts with a prevalence of 1-10% for unselected population, 2-8% for infertile women and 5-30% for women with a history of miscarriage. Uterine anomalies are implicated as cause of reduced fertility as well as early pregnancy loss. Moreover, their presence is related to an increased risk of preterm birth, abnormal fetal presentation, cesarean delivery, placental abruption and small-for-gestational age infants. The presented study aims to evaluate the correlation between congenital uterine anomalies and poor perinatal outcomes. This was a retrospective, single-center cohort study including 29 women with congenital uterine anomalies. The control group included 100 women hospitalized for delivery with normal uterine morphology. Primary perinatal outcome was preterm birth (delivery before the 37th week of gestation); secondary endpoints were fetus small for gestational age (SGA) (< 10th percentile weight) and fetal abnormal presentation (non-cephalic presentation at the end of pregnancy). Data are presented as median or frequency. Correlations were compared using Mann-Whitney or Pearson’s chi square test. Statistical tests were considered significant if P < 0.05. Preterm birth, fetal abnormal presentation, small for gestational age fetuses were significantly higher (P < 0.001) in the congenital uterine malformations group. Congenital uterine anomalies are associated with poor perinatal outcomes; moreover, our study shows that type of malformations mostly associated with worse reproductive outcomes are the septate uterus and sub-septate uterus.

Published: February 2021

Objective: This study aims to determine the protective effects of apocynin, a NADPH oxidase inhibitor, and melatonin, an endogenous anti-oxidant, in an animal model of ovarian ischemia/reperfusion (I/R) injury. Materials/Methods: Thirty-five female rats were randomly divided into five groups, namely group I (sham), group II (I/R), group III (I/R + 10 mg/kg apocynin), group IV (I/R + 20 mg/kg apocynin), and group V (I/R + 10 mg/kg melatonin). Ovarian tissue and serum superoxide dismutase (SOD) and catalase (CAT) activities and malondialdehyde (MDA) and protein carbonyl (PC) levels were measured. Ovarian histopathology was examined and Bax, caspase 3, and iNOS immunoreactivities were evaluated. Results: Preoperative apocynin and melatonin significantly increased SOD and CAT activities (P < 0.05, P < 0.05, P < 0.01, P < 0.01, P < 0.01, P < 0.05, P < 0.05, and P < 0.01, respectively, for both apocynin and melatonin). In addition, preoperative apocynin and melatonin significantly decreased the ovarian I/R injury score (P < 0.01 for both). Bax, caspase 3, and iNOS immunoreactivities were significantly lower in the I/R + 10 mg/kg apocynin and I/R + 10 mg/kg melatonin groups than in the I/R group (P < 0.01, P < 0.01, P < 0.01, P < 0.01, P < 0.05, and P < 0.01, respectively). Conclusions: Apocynin and melatonin are powerful anti-oxidant agents with considerable bioavailability and safety. Preoperative apocynin and melatonin administration might protect ovarian tissue from I/R injury after surgical adnexal detorsion.

Published: February 2021

Kinship greeting becomes a sign of culture, tribe, and race of a family. The greeting word used to call or greet someone, some of them survive, shift, or extinct because of various problems and environments. This condition encourages the implementation of analysis about the retention, shift, and extinction of kinship greetings seen from the line of descent in the society of Siak Malay. The method used to collect the data was in the form of an interview. The activity was conducted towards one of the Malay families who were born and stayed in Siak. The analysis and data discussion was by describing the form of kinship greetings based on the line of descent. The analysis results find out that there is a greeting word that does not show the identity of culture, tribe, and race of a family, such as Oom, Gan, and Lok. Meanwhile, there is also a shift of greeting words caused by the grandmother, such as To Odang, To Udo, and To Ocu. Besides, on the line of the grandfather, there are greeting words like Pak/Mak Tuo (first child), Ongah (second child), Udo (the third child), Pak/Mak Ocu/Oncu (the fourth child and so on). Then, the descent of son greets the brother of their father with greeting word Apak. These data show that there are still efforts of a family to maintain the form of the greetings. The extinction causes the loss of culture trait, tribe, and race of a family

This article will carry out an analysis of female participation in science,considering the Brazilian system of graduate studies and scientific research as a casestudy. Goals. Considering that science is a central supporting structure for modernsocieties, a detailed analysis of the scientific power structure behind academic policycreation can reveal aspects of androcentrism in scientific activity. The main goal of thiswork is to identify the process of misogyny in science through the description of itsreproductive pattern. Theoretical and methodological procedures. The concept of ascientific field developed by Bourdieu is used to analyze the data identifying thedynamic structure of misogyny in science. Initially, a historical and present-day outlineis constructed in such a manner. This panoramic description is analyzed, taking intoconsideration the essential elements for knowledge production in Brazil, includingwomen participation in the initial levels of scientific research as undergraduate andgraduate students, in the organization of research groups, and in their participation atsenior management positions in science. Results. A significant increase in femalepercentage in scientific activities is observed at the initial and intermediary levels,except for the most prestigious areas as hard science. However, a scissor effect isidentified between the initial level and the more prominent positions. At the top of thescientific career, the presence of women is extremely low. This unbalanced participationreveals that female occupations in science are basically as labor force since in thiscareer, women are quite far from the social circles of decisions.

Published: February 2021

BACKGROUND: 3D bioprinting cardiac patches for epicardial transplantation is a promising approach for myocardial regeneration. Challenges remain such as quantifying printability, determining the ideal moment to transplant and promoting vascularisation within bioprinted patches. We aimed to evaluate 3D bioprinted cardiac patches for printability, durability in culture, cell viability and endothelial cell structural self-organisation into networks. METHODS: We evaluated 3D-bioprinted double-layer patches using alginate/gelatine (AlgGel) hydrogels and three extrusion bioprinters (REGEMAT3D; INVIVO; BIO X). Bioink contained either neonatal mouse cardiac cell spheroids or free (not-in-spheroid) human coronary artery endothelial cells with fibroblasts, mixed with AlgGel. To test effects on durability, some patches were bioprinted as a single layer only, cultured under minimal movement conditions or had added fibroblast-derived extracellular matrix hydrogel (AlloECM). Controls included acellular AlgGel and gelatin methacryloyl (GELMA) patches. RESULTS: Printability was similar across bioprinters. For AlgGel compared to GELMA: resolutions were similar (200-700μm line diameters), printing accuracy was 45% and 25%, respectively (AlgGel was 1.7x more accurate;p<0.05), shape fidelity was 92% (AlgGel) and 96% (GELMA);p=0.36. For durability, AlgGel patch median survival in culture was 14 days (IQR:10-27) overall which was not significantly affected by bioprinting system or cellular content in patches. We identified three factors which reduced durability in culture: 1) bioprinting one layer depth patches (instead of two layers); 2) movement disturbance to patches in media; 3) the addition of AlloECM to AlgGel. Cells were viable after bioprinting followed by 28 days in culture and all BIO X-bioprinted mouse cardiac cell spheroid patches presented contractile activity starting between day 7 and 13 after bioprinting. At day 28, endothelial cells in hydrogel displayed organisation into endothelial network-like structures. CONCLUSIONS: AlgGel-based 3D bioprinted heart patches permit cardiomyocyte contractility and endothelial cell structural self-organisation. After bioprinting, a period of 2 weeks' maturation in culture prior to transplantation may be optimal, allowing for a degree of tissue maturation but before many patches start to lose integrity. We quantify AlgGel printability and present novel factors which reduce AlgGel patch durability (layer number, movement and the addition of AlloECM) and factors which had minimal effect on durability (bioprinting system and cellular patch content).

CCDC102A is a differentially expressed gene in brain metastatic human breast cancer.
Authors: Mamoor Shahan
Published: February 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that coiled-coil domain containing 102A, encoded by CCDC102A, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. CCDC102A mRNA was present at decreased quantities in brain metastatic tissues as compared to primary tumors of the breast. Importantly, expression of CCDC102A in primary tumors was correlated with patient overall survival. Modulation of CCDC102A expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Intrapersonal Mindfulness is Associated with Reduced Risk of Burnout among Central Appalachian Educators
Authors: Anama-Green Chris
Published: February 2021

IntroductionNational statistics suggest that up to 40% of new teachers will leave their school or the teaching profession within their first five years of teaching. Much of this attrition is associated with work-related burnout, some of which may be preventable with targeted worksite health interventions. Previous research suggests that mindfulness skills may be protective from burnout, ultimately reducing the likelihood of attrition from the profession.MethodsThis study compared the self-reported levels of burnout and secondary traumatic stress with participants’ levels of interpersonal and intrapersonal mindfulness. Participants completed the Professional Quality of Life Inventory and the Mindfulness in Teaching Inventory. Odds Ratios and Relative Risks were calculated using Epi Info. Pearson correlations, linear regression, and ANOVA analyses were completed using SPSS. Chronbach’s alpha values were also calculated to evaluate score reliability of the five constructs.ResultsRelative Risks and Odds Ratios of having secondary traumatic stress scores of “average/high” were significantly lower for those with high intrapersonal mindfulness scores. Those who reported high intrapersonal mindfulness scores were up to 11 times more likely to report “low” burnout than those who reported low intrapersonal mindfulness scores. Burnout negatively correlated with both intrapersonal mindfulness suggesting that as intrapersonal mindfulness level decreases, burnout increases. ANOVA testing identified significant differences in burnout based on intrapersonal mindfulness level.ConclusionThose who reported high levels of intrapersonal mindfulness had significantly reduced risk of burnout. These results will inform further research in the region regarding mindfulness practice and the experience of burnout among teachers in the region. Thus, mindfulness may be protective from occupation-related burnout for this population. Interventions informed by additional research could reduce the burden of occupation-related burnout and may ultimately contribute toward reduced attrition in the teaching profession.

Objective: The goal of this study was to examine whether neural sensitivity to peer rejection, a potent form of social evaluative threat in adolescence, conveys risk for depression among anxious youth. We hypothesized that brain activation in regions that process affective salience in response to rejection from virtual peers would predict depressive symptoms one year later and would be associated with ecological momentary assessment (EMA) reports of real-world peer connectedness. Method: Participants were 38 adolescents ages 11-16 (50% female) with a history of anxiety, recruited from a previous clinical trial. The present study was a prospective naturalistic follow-up of depressive symptoms assessed 2 years (Wave 2) and 3 years (Wave 3) following treatment. At Wave 2, participants completed the Chatroom Interact Task during neuroimaging and 16 days of EMA. Results: Controlling for depressive and anxiety symptoms at Wave 2, subgenual anterior cingulate (sgACC;\ \beta=.39, p=.010) and nucleus accumbens activation (NAcc;\beta=.30, p=.041) to peer rejection (vs. acceptance) predicted depressive symptoms at Wave 3. SgACC activation to rejection (vs. acceptance) was highly correlated with EMA reports of connectedness with peers in daily life (r=-.71, p<.001). Conclusion: Findings suggest that elevated sgACC and NAcc activation to rejection may serve as a risk factor for the development of depressive symptoms among anxious youth, perhaps by promoting vigilance or reactivity to potential social evaluative threats and subsequent avoidance behaviors. SgACC activation to simulated rejection appears to have implications for understanding how adolescents experience their daily social environments in ways that could contribute to depressive symptoms.

Authors: Maskey Bunty , Subedi Sarmila , Shrestha Nabindra Kumar
Published: February 2021

The paper aims to determine the effect of jackfruit seed flour incorporation on the quality of cookies. D-optimal mixture design has been employed for formulating the recipe of cookies. Five different formulations of cookies containing 0, 12.5, 25, 37.5, and 50 parts jackfruit seed flour were prepared. The prepared cookies are subjected to sensory evaluation by ten semitrained panelists for consumer acceptability. The obtained data have been statistically analyzed using two-way ANOVA (no blocking) at 5% level of significance. From the mean sensory scores, 12.5 parts jackfruit seed flour incorporation was selected as the best formulation and subjected to proximate analysis. The protein, fat, fiber and ash contents are significantly (p<0.05) higher in jackfruit seed flour incorporated cookies than wheat flour cookies (control). The phytate and oxalate contents were also found to be significantly (p<0.05) higher in jackfruit seed flour incorporated cookies than control but were below tolerance level and safe for consumption.
Interplay of Power Relations in Neeharika’s Yogmaya: A Foucauldian Discourse Analysis
Authors: Niraula Tirtha Raj
Published: February 2021

This article aims at exploring how Neelam Karki Niharika‘s Yogmaya presents the complex web of power relations that comprise domination, submission, and resistance. It mainly draw son Michel Foucault‘s idea that power is pervasive, not just oppressive but productive as well. Viewed from the Foucauldian notion of power as a theoretical framework, the study reveals the interplay of dominant and counter discourses in propagating knowledge and truth that are constructed and reconstructed. The novel is treated as a site of struggle where the state power along with the discourses of religion, patriarchy, and gender roles prominently operate so as to suppress the voice of the dissent. Yogmaya, a rural woman of the humble background, continuously resists both verbally and physically against various forms of power in the face of threats. She exercises her power in the same way as those who traditionally believe they possess it. In this connection, the focus lies on the protagonist‘s persistent attempts of resistance through the bold interrogation of the hegemonizing discourses and regimes of truth. As the text under study is written in Nepali, I use transliteration and free translation in order to cite the lines for analysis.

Actualización del síndrome de ovario poliquístico
Authors: Orias Vásquez Mary
Published: February 2021

El síndrome de ovarios poliquísticos es el más común de las endocrinopatías en mujeres. Afecta principalmente a las mujeres en edad reproductiva. Es una enfermedad de etiología desconocida, pero se cree que es multifactorial. Se manifiesta clínicamente con alteraciones menstruales, infertilidad, hirsutismo, acné, obesidad y resistencia a la insulina. Para su diagnóstico, es necesario excluir otras patologías que causen trastornos del ciclo menstrual y exceso de andrógenos, y cumplir con al menos dos de los siguientes criterios: oligomenorrea/amenorrea, hiperandrogenismo clínico y/o bioquímico, ovarios poliquísticos por ecografía. El tratamiento debe ser individualizado y enfocado en la regulación de los trastornos menstruales y en el deseo de concebir de la paciente.
