We investigated the association between the amount and duration of smoking on biochemical, clinical parameters and the ovarian morphology in women with polycystic ovary syndrome (PCOS). That was a retrospective study. These women were divided into two groups, non-smokers (217) and smokers (92). The amount of cigarettes and duration of smoking was measured in pack-years. Both groups underwent clinical evaluation, biochemical and hormone analysis, transvaginal ultrasound and oral glucose tolerance tests (OGTT). The mean value of the number of cigarettes was 14.8 (±8.8) and the median value of pack-years in the smokers group was 4.0 (1.5-7.5). Smokers group has significantly higher free testosterone (F-T), 17-hydroxyprogesterone (17-OHP), delta 4 androstenedione (Δ4-A), T4, low-density lipoprotein (LDL), and white blood cells (WBC). During correlation of all the above parameters and pack-years, there has been significant positive correlation in F-T and Δ4-A. The participants with more pack-years showed statistically higher values of F-T and Δ4-A. There was also a significant positive correlation between total cholesterol, triglycerides, WBC and pack-years of the participants. Prolactin (PRL) has been inversely associated with pack-years. We concluded that the increase of pack-years aggravated lipid profile, WBC and decreased PRL levels, in PCOS patients.

ProblemTo study the balance of circulating heat shock protein (HSP)60 and HSP70 in pre‐term delivery.Method of studyA two‐stage approach was used. At first stage, we run retrospective analysis of prospective collected clinical data, and at a second stage, we studied an animal model of pre‐term delivery (PTD). Blood samples were collected for prenatal screening in 3629 women. Samples from 23 women with miscarriage before gestational week 21 and 53 well‐matched comparators for age, body mass index, parity, and previous miscarriage with full‐term pregnancy were depicted. Women with risk factors were excluded. HSP60 and HSP70 were measured by an enzyme immunosorbent assay. PTD was induced after injection of low dose of bacterial lipopolysaccharide; mice were killed for the measurement of HSP60 and HSP70 in blood and tissues. The study endpoint was the association of the HSP60 to HSP70 ratio to miscarriage.ResultsA ratio >6 could distinguish between women who will miscarry from women with term pregnancies with sensitivity 60%, specificity 81.8%, positive predictive value 81.8%, and negative predictive value 60% (OR: 6.750, P = 0.025). Mice of the LPS‐group PTD had this ratio significantly increased in maternal serum, placentas, and embryos compared to the sham‐operation group. Gene expression of hsp60/70 remained in tissues unaltered.ConclusionA HSP60/HSP70 ratio equal to or more than 6 until gestational week 12 is accompanied with great likelihood for miscarriage. A similar ratio applies in an animal model of PTD induced by low‐dose LPS.

Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed an appendiceal mucocele, for which she received a full oncological procedure. The histology report showed a low-grade appendiceal mucinous neoplasm, and the patient underwent six cycles of chemotherapy. Appendiceal tumors should be kept in mind in patients with adnexal mass.

Background: Polycystic ovary syndrome (PCOS) is closely related to various adverse cardiovascular manifestations and increased cardiovascular risk. However, atrial fibrillation (AF) development and atrial conduction abnormalities have not been thoroughly studied in patients with PCOS. Methods: This meta-analysis (CRD42021261375) was conducted in accordance with the PRISMA guidelines. Our aim was to investigate associations between PCOS and disorders in atrial conduction parameters linked with an increased risk for AF occurrence. Results: Five cohort studies with aggregate data on 406 adult women (229 with PCOS and 177 age-matched without PCOS) were included in this analysis. Our results showed a significantly increased mean difference in P-wave maximum duration (+7.63 ± 7.07 msec; p < 0.01) and P-wave dispersion (+11.42 ± 5.22 msec; p = 0.03) of patients with PCOS compared to healthy women. The mean difference in P-wave minimum duration (−2.22 ± 2.68 msec; p = 0.11) did not reach the statistical threshold between the compared groups. Echocardiographic measurements of atrial electromechanical delay (AED) also indicated a statistically significant mean difference in favour of the PCOS group in all assessed parameters, except for atrial electromechanical coupling (PA) in the tricuspid annulus. Particularly, PCOS was associated with increased lateral PA, septal PA, inter- and intra-AED durations (mean difference: +17.31 ± 9.02 msec; p < 0.01, +11.63 ± 7.42 msec; p < 0.01, +15.31 ± 9.18 msec; p < 0.01, +9.31 ± 6.85 msec; p < 0.01, respectively). Conclusions: PCOS is strongly associated with alterations in several electrocardiographic and echocardiographic parameters indicating abnormal atrial conduction. Therefore, PCOS could be considered as a causal or triggering factor of AF. Larger studies are needed to confirm these results and investigate direct associations between PCOS and AF.

HIF-1α expression is affected by anemia, although this factor has no important direct effect on the perinatal outcome.
