To compare the medical image interpretation's time between the conventional and automated methods of breast ultrasound in patients with breast lesions. Secondarily, to evaluate the agreement between the two methods and interobservers.
This is a cross-sectional study with prospective data collection. The agreement's degrees were established in relation to the breast lesions's ultrasound descriptors. To determine the accuracy of each method, a biopsy of suspicious lesions was performed, considering the histopathological result as the diagnostic gold standard.
We evaluated 27 women. Conventional ultrasound used an average medical time of 10.77 minutes (± 2.55) greater than the average of 7.38 minutes (± 2.06) for automated ultrasound (p<0.001). The degrees of agreement between the methods ranged from 0.75 to 0.95 for researcher 1 and from 0.71 to 0.98 for researcher 2. Among the researchers, the degrees of agreement were between 0.63 and 1 for automated ultrasound and between 0.68 and 1 for conventional ultrasound. The area of the ROC curve for the conventional method was 0.67 (p=0.003) for researcher 1 and 0.72 (p<0.001) for researcher 2. The area of the ROC curve for the automated method was 0. 69 (p=0.001) for researcher 1 and 0.78 (p<0.001) for researcher 2.
We observed less time devoted by the physician to automated ultrasound compared to conventional ultrasound, maintaining accuracy. There was substantial or strong to perfect interobserver agreement and substantial or strong to almost perfect agreement between the methods.

Dysmenorrhea is the pain related to menstruation; to screen for the symptoms, a working ability, location, intensity of days of pain, and dysmenorrhea (WaLIDD) score was created. The purpose of this work was to culturally adapt and assess the measurement properties of the WaLIDD score for dysmenorrhea in Brazilian women.
In this cross-sectional online study, we evaluated women with and without dysmenorrhea. Criterion validity and construct validity were assessed, respectively, by the Receiver Operator Characteristic (ROC) curve and correlations with the bodily pain and social functioning domains of medical outcomes study 36-item short-form health survey (SF-36), self-report of absenteeism and Stanford Presenteeism Scale for presenteeism. Test-retest reliability and measurement errors were assessed, respectively, by intraclass correlation coefficient (ICC) and Bland and Altman Graph.
430 women completed the test, 238 (55.4%) women had dysmenorrhea, and 199 (46.3%) answered the questionnaire twice for the retest. The cutoff points ≥4, ≥5, and ≥5 could discriminate between women with and without dysmenorrhea, absenteeism, and presenteeism related to dysmenorrhea, respectively. Correlations between SF-36 – pain and social functioning domains and WaLIDD score were weak to strong and negative. For WaLIDD total Score, ICC was 0.95 and the limits of agreement were −1.54 and 1.62.
WaLIDD score is a short, valid and reliable instrument to screen and predict dysmenorrhea and could predict absenteeism and presenteeism related to dysmenorrhea in Brazilian women.

, , , , , To determine the prevalence of anxiety, depression and burnout in residents of Gynecology and Obstetrics during COVID-19 pandemic in Brazil and its associated factors.
Cross-sectional study involving all regions of Brazil, through the application of a sociodemographic questionnaire, the Hospital Anxiety and Depression Scale (HAD) and the Maslach Burnout Inventory (MBI-HSS) instrument. Multivariate analysis was performed after adjusting the Poisson model.
Among the 719 participating medical residents, screening was positive for anxiety in 75.7% and for depression in 49.8% of cases. Burnout syndrome was evidenced in 41.3% of the physicians studied. Those with depression are more likely to have anxiety (OR 0.797; 95%CI 0.687 - 0.925) and burnout syndrome (OR 0.847 95%CI 0.74 - 0.97). Residents with anxiety (OR 0.805; 95%CI 0.699 - 0.928) and burnout (OR 0.841; 95%CI 0.734 - 0.963) are more likely to have depression.
High prevalence of anxiety, depression and burnout were found in residents of Gynecology and Obstetrics in Brazil, in addition to important correlations between anxiety-depression and depression-burnout.

This was a multi-center, retrospective, observational, cross-sectional, and descriptive study across 817 centers in India. Data of patients who received dydrogesterone in past and provided consent for future use of their medical record for research purpose was were retrieved and analyzed.
Data of 7287 subjects (aged 29.55±4.84 years) was analyzed. Threatened abortion was the most common indication for which the subjects received dydrogesterone (46.9%) followed by recurrent pregnancy loss. Polycystic ovary syndrome (PCOS), thyroid disorders and anemia were the most common comorbid conditions and prior pregnancy loss, advanced maternal age and obesity were the most common risk factors seen in subjects who received dydrogesterone. Total 27.5% of subjects received a loading dose of dydrogesterone, and majority (64%) received 40 mg as loading dose. 10 mg dose was used as maintenance or regular dose in 81.4% of the subjects. Twice daily (BID) was the most common dosing frequency (66.6%). The most common concomitant medications being taken by the subjects on dydrogesterone included folic acid (45.1%), iron supplements (30.3%) and calcium and vitamin D3 supplements (25.5%). Another progesterone preparation (oral, injection, vaginal, tubal) other than dydrogesterone was used concurrently in 7.8% of subjects.
The study helped to identify the patient population that is benefitted by dydrogesterone and the preferred indications, risk factors, comorbid conditions and concomitant medication used in this patient population at real-life scenario.

, , , , , , , To examine whether the DDAH2 promoter polymorphisms -1415G/A (rs2272592), -1151A/C (rs805304) and -449G/C (rs805305), and their haplotypes, are associated with PE compared with normotensive pregnant women, and whether they affect ADMA levels in these groups.
A total of 208 pregnant women were included in the study and classified as early-onset (N=57) or late-onset PE (N =49), and as normotensive pregnant women (N = 102).
Pregnant with early-onset PE carrying the GC and GG genotypes for the DDAH2 -449G/C polymorphism had increased ADMA levels (P=0.01). No association of DDAH2 polymorphisms with PE in single-locus analysis was found. However, the G-C-G haplotype was associated with the risk for late-onset PE.
It is suggested that DDAH2 polymorphisms could affect ADMA levels in PE, and that DDAH2 haplotypes may affect the risk for PE.

, , , , Potassium channels have an important role in the vascular adaptation during pregnancy and a reduction in the expression of adenosine triphosphate-sensitive potassium channels (Katp) has been linked to preeclampsia. Activation of Katp induces vasodilation; however, no previous study has been conducted to evaluate the effects of the inhibition of these channels in the contractility of preeclamptic arteries. Glibenclamide is an oral antihyperglycemic agent that inhibits Katp and has been widely used in vascular studies.
To investigate the effects of the inhibition of Katp, umbilical arteries of preeclamptic women and women with healthy pregnancies were assessed by vascular contractility experiments, in the presence or absence of glibenclamide. The umbilical arteries were challenged with cumulative concentrations of potassium chloride (KCl) and serotonin.
There were no differences between the groups concerning the maternal age and gestational age of the patients. The percentage of smokers, caucasians and primiparae per group was also similar. On the other hand, blood pressure parameters were elevated in the preeclamptic group. In addition, the preeclamptic group presented a significantly higher body mass index. The newborns of both groups presented similar APGAR scores and weights.
In the presence of glibenclamide, there was an increase in the KCl-induced contractions only in vessels from the PE group, showing a possible involvement of these channels in the disorder.

The aims of the study are to describe the association of coronavirus disease (COVID-19) with the abnormal histopathological findings in human placenta and to highlight the potential predictors of these histopathological findings.
A retrospective cohort study, held in two obstetric units from January 2021- 2022, 34 patients who were confirmed cases of COVID- 19 were followed up till the time of delivery as their placenta were sent for histopathology. Patients diagnosed with other viral infections, chorioamnionitis, or were known case of as pre-term or term pre labour rupture of membrans (PROM) were excluded as well as pre exisiting diabetes mellitus or pre-eclampsia. Data analysis were performed using STATA software version 16.
Specific histopatological findings (fetal vascular malperfusion, maternal vascular malperfusion, inflammatory pathology and thrombotic finding) were significantly high among 13 (38.2%) of the study group who got infected earlier in pregnancy (P<0.001). The period between the diagnosis of COVID-19 and the delivery significantly increases the odds of the presence of pathological findings by 2.75 times for each week the patients getting infected earlier.
Association of abnormal placental histopathological findings with COVID-19 infection in pregnancy and the potential predictor for the occurrence of placental findings is the longer duration between the diagnosis of the infection and the delivery.

This is a cross-sectional observational study involving women in the community aged 40–55 years in the Southern region of Brazil. They completed a general health, habits and socio-demographic questionnaire, the CS-10 and the Women’s Health Questionnaire (WHQ). Women unable to understand the survey, not consenting to participate, or having incapacity imposing difficulties during the completion of the questionnaire were excluded. A Confirmatory Factor Analysis (CFA) was conducted with the AMOS 16.0 software. Chi-square of degrees of freedom (χ2/df), the Comparative Fit Index (CFI), the Tucker-Lewis Index (TLI) and the Root-Mean-Square Error of Approximation (RMSEA) were used as indices of goodness of fit. Cronbach’s alpha coefficient was used for internal consistency.
A total of 422 women were included (premenopausal n=35, perimenopausal n=172, postmenopausal n=215). The CFA for the CS-10 showed a good fit (χ²/df=1.454, CFI=0.989; TLI=0.985; RMSEA=0.033; CI 90%=0.002-0.052; PCLOSE=0.921; Model p=0.049). Good reliability was established in CS-10 and WHQ (Cronbach’s alpha=0.724). Postmenopausal women had higher total CS-10 scores (p≤0.0001), reflecting worse quality of life (QoL) related to menopause symptoms and confirming the greater symptomatology evaluated by high total scores for WHQ found in this population when compared to those in the premenopausal period (p=0.041).
The CS-10 is a consistent tool for health-related QoL in Brazilian mid-aged women.
