RESUMEN

Local estrogen therapy (LET) is the mainstay of treatment for vaginal dryness, dyspareunia and other urogenital symptoms because it may reverse some pathophysiological mechanisms associated with decreasing endocrine function and increasing aging. Over the years, several vaginal products including different formulations (tablets, rings, capsules, pessaries, creams, gels and ovules) and molecules (estradiol [E2], estriol [E3], promestriene, conjugated equine estrogens and estrone) have been used with superimposable therapeutic results. Low-dose and ultra-low-dose LET is the gold standard due to its minimal systemic absorption, with circulating E2 levels persistently remaining in the postmenopausal range. In healthy postmenopausal women, preference among the various products is presently the main driver and dissatisfaction with LET seems high, namely because of the delayed use in those with severe symptoms of genitourinary syndrome of menopause (GSM). Specific concerns remain in high-risk populations such as breast cancer survivors (BCS), especially those under treatment with aromatase inhibitors. Based on the multitude of symptoms under the umbrella of GSM definition, which includes vulvovaginal atrophy (VVA), it is mandatory to investigate specific effects of LET on quality of life, sexual function and genitourinary conditions by conducting studies with a patient-tailored focus.

RESUMEN

OBJECTIVE: About 30% of Adult type granulosa cell tumors of the ovary (AGCTs) are diagnosed in fertile age. In stage I, conservative surgery (fertility-sparing surgery, FSS), either unilateral salpingo-oophorectomy (USO) or cystectomy are possible options. The aim of this study is to compare oncological outcomes of FSS and radical surgery (RS) in apparently stage I AGCTs treated within the MITO group (Multicenter Italian Trials in Ovarian cancer). METHODS: Survival curves were calculated using the Kaplan-Meier method and compared with log-rank test. The role of clinicopathological variables as prognostic factors for survival was assessed using Cox's regression. RESULTS: Two-hundred and twenty-nine patients were included; 32.6% received FSS, 67.4% RS. In the FSS group, 62.8% underwent USO, 16.7% cystectomy, 20.5% cystectomy followed by USO. After a median follow up of 84 months, median DFS was significantly worse in the FSS-group (10 yr DFS 50% vs 74%, in FSS and RS group, p = 0.006). No significant difference was detected between RS and USO (10 yr DFS 75% vs 70%, p = 0.5).Cystectomy-group showed a significantly worse DFS compared to USO (10 yr DFS 16% vs 70%, p < 0.001). Patients receiving cystectomy and subsequent USO showed a better prognosis, even though significantly worse compared to USO (10 yr DFS 41% vs 70%, p = 0.05). Between FSS and RS, no difference in OS was detected. At multivariate analysis, FIGO stage IC and cystectomy retained significant predictive value for worse survival. CONCLUSIONS: This study supports the oncological safety of FSS in stage I AGCTs, provided that cystectomy is avoided; USO should be the preferred approach.

RESUMEN

Sexuality in women with spontaneous premature ovarian insufficiency (POI) deserves attention because of the young age and the distressing impact of such a life-changing diagnosis. Biomedical and psychosocial factors work in concert to determine significant changes of sexual function. Early hormonal deprivation gives origin to symptomatic vulvovaginal atrophy and contributes to hypoactive sexual desire disorder modulating central and peripheral circuitries, which regulate sexual response. Emotional and cognitive adjustment to the short-term and long-term consequences of POI may further determine negative attitudes toward sexuality. It is essential to counsel POI women on every aspect of their life, from menopausal symptoms to fertility concerns, from health risks to potential therapeutic solutions. The biopsychosocial perspective is the best approach to manage sexual symptoms, including tailored hormone therapy and focused counseling. Pharmacotherapies specifically investigated in spontaneous POI conditions are lacking and clinical judgment has to guide the choice of treatment, which must be continued at least until the average age at natural menopause according to the most recent guidelines. Further studies are needed to better characterize POI women and to understand the effective role of novel therapeutic strategies, including androgens and cognitive-behavioral and sexual interventions.

RESUMEN

Background: Surgery followed by platinum-based chemotherapy is the standard of care for MOGCTs, except for stage IA dysgerminoma and stage IA grade 1 immature teratoma where surveillance only is recommended. The role of adjuvant chemotherapy and surgical staging is debated. Patients and methods: Data from 144 patients with stage I MOGTs were collected among MITO centers (Multicenter Italian Trials in Ovarian Cancer) and analyzed. Results: Fifty-five (38.2%) patients were affected by dysgerminomas, 49 (34%) by immature teratomas, 26 (18.1%) by yolk sac tumors and 14 (9.7%) by mixed tumors. Seventy-three (50.7%) patients receive surgery plus chemotherapy, while 71 (49.3%) patients underwent surgery alone. The latter group included 32 dysgerminomas (14 IA-13 Ix, 3 IB, and 2 IC), 34 immature teratomas (20 1A-13 IA grade 1, 6 Ix, 1 IB, and 7 IC), 4 mixed tumors and 1 yolk sac tumor. Forty-four patients did not received chemotherapy, even if it would have been indicated by recommended approach. 94 (65.3%) patients received peritoneal surgical staging. Twenty-three (15.9%) developed a recurrence. Incomplete surgical staging was associated with recurrence (P < 0.05; OR 2.37) at Cox regression analysis. Seven patients died. Four patients were affected by yolk sac tumors, two by mixed tumors and one by immature teratoma. Five patients died for disease, one for acute leukemia and one for suicide. Prognostic parameter analyses showed that yolk sac component is a predictor for survival (P < 0.05). Five-years OS rates were 96.8% and 88.7% in the surgically staged and the incomplete staged group, respectively, while 93.8% and 94.1% in the standard treatment and in the surveillance group, respectively. Conclusions: This study shows that surveillance seems not to affect survival; chemotherapy should be reserved for relapse resulting in high cure rate. Incomplete peritoneal surgical staging is associated with recurrence. Yolk sac histology worsens the prognosis.

RESUMEN

When deciding how to pre-process EEG data, researchers need to make a choice at each single step of the procedure among different possibilities, equally valid. Therefore, in this work, we illustrate how these decisions may affect the quality of the final cleaned data in an Action Observation/Motor Imagery protocol, using quantitative indices. In particular, we showed the effect of segmenting or not the data in epochs around the stimulus presentation time on the independent component analysis (ICA) used for artifact removal. For ICA analysis, we tested two algorithms (SOBI and Extended Infomax). Finally, three re-reference approaches (Common averaged reference-CAR, robust-CAR and reference electrode standardization technique - REST) were also applied and their effects compared. Results showed that the segmenting method has a prominent effect on the cleaning procedure and consequently on final EEG data quality. Extended Infomax is confirmed as the method of choice for the identification of the artifactual components and, finally, CAR and the REST re-referencing techniques led to similar good results.

RESUMEN

Gestational Diabetes Mellitus (GDM) and obesity affect the functioning of multiple maternal systems and influence colonization of the newborn gastrointestinal through the breastmilk microbiota (BMM). It is currently unclear how GDM and obesity affect the human BMM composition. Here, we applied 16S-rRNA high-throughput sequencing to human colostrum milk to characterize BMM taxonomic changes in a cohort of 43 individuals classified in six subgroups according to mothers patho-physiological conditions (healthy control (n = 18), GDM (n = 13), or obesity (n = 12)) and newborn gender. Using various diversity indicators, including Shannon/Faith phylogenetic index and UniFrac/robust Aitchison distances, we evidenced that BMM composition was influenced by the infant gender in the obesity subgroup. In addition, the GDM group presented higher microbial diversity compared to the control group. Staphylococcus, Corynebacterium 1, Anaerococcus and Prevotella were overrepresented in colostrum from women with either obesity or GDM, compared to control samples. Finally, Rhodobacteraceae was distinct for GDM and 5 families (Bdellovibrionaceae, Halomonadaceae, Shewanellaceae, Saccharimonadales and Vibrionaceae) were distinct for obesity subgroups with an absolute effect size greater than 1 and a q-value ≤ 0.05. This study represents the first effort to describe the impact of maternal GDM and obesity on BMM.

RESUMEN

OBJECTIVE: Surgery represents the mainstay of treatment of stage I adult type granulosa cell tumors of the ovary (AGCTs). Because of the rarity and indolent course of the disease, no prospective trials are available. Open surgery has long been considered the traditional approach; oncological safety of laparoscopy is only supported by small series or case reports. The aim of this study was to compare the oncological outcomes between laparoscopic and open surgery in stage I AGCTs treated within the MITO (Multicenter Italian Trials in Ovarian cancer) Group. METHODS: Data from patients with stage I AGCTs were retrospectively collected. Clinicopathological features were evaluated for association with relapse and death. Survival curves were calculated using the Kaplan-Meier method and compared with the log-rank test. The role of clinicopathological variables as prognostic factors for survival was evaluated using Cox's regression model. RESULTS: 223 patients were identified. Stage 1A, 1B and 1C were 61.5%, 1.3% and 29.6% respectively. 7.6% were apparently stage I. Surgical approach was laparoscopic for 93 patients (41.7%) and open for 130 (58.3%). 5-years DFS was 84% and 82%, 10-years DFS was 68% and 64% for the laparoscopic and open-group (p = 0.6).5-years OS was 100% and 99%, 10 years OS was 98% and 97% for the laparoscopic and open-surgery group (p = 0.8). At multivariate analyses stage IC, incomplete staging, site of primary surgery retained significant prognostic value. CONCLUSION: The present study suggests that surgical route does not affect the oncological safety of patients with stage I AGCTs, with comparable outcomes between laparoscopic and open approach.

RESUMEN

The aim of the present study was to evaluate the effect of iron overload on gene expression in HepG2 cells by differential display. Iron-treated cells showed a 50% decrease in apolipoprotein B100 (Apo B100) and a 2- and 3-fold increase in semaphorin cd100 and aldose reductase mRNA, respectively, with parallel variations in Apo B100 and aldose reductase proteins. These effects were time-dependent. Vitamin E prevented the increase in aldose reductase expression, but had no effect on Apo B100 and semaphorin cd100. Treatment with hydrogen peroxide and 4-hydroxy-2,3-nonenal increased only aldose reductase mRNA. These data suggest that iron can affect mRNA levels by lipid peroxidation-dependent and -independent pathways.

RESUMEN

Weekly determinations of the fatty acid/albumin molar ratio (FA/SA) were obtained 136 times on 50 neonates (birthweight range, 675-4300 grams; median, 1360 grams) to determine if our use of intravenous fat (IVF) was putting these newborns at risk for kernicterus. The FA/SA was measured using a convenient spectrophotometric technique which we have previously described (Berde CB, Kerner JA, Johnson JD: Clin Chem 26:1173-1177, 1980). Twenty-nine infants received IVF with doses from 0.5 to 3.3 gram/kilogram/day (mean 1.5 gram/kilogram/day), given over 24 hours whenever possible, most commonly begun in the second week of life when the bilirubin level was less than one half of the potential exchange level. Twenty-one infants received no IVF. Previous studies show that fatty acids do not begin to displace bilirubin from albumin until the FA/SA is greater than 6 in vivo, and greater than 4 in vitro. All our infants had safe values with mean FA/SA values of approximately 1.0. Continuous IVF as we administer it does not place neonates at risk for kernicterus. Centers administering IVF in the first week of life or by bolus should consider close monitoring of their infants with the FA/SA.

RESUMEN

The increasing use of sevoflurane as anaesthetic leads to the need for finding a biological index to evaluate the occupational exposure in surgical activity. Several studies indicate that Hexafluoroisopropanol (HFIP) is a specific sevoflurane metabolite quickly glucuronidated and excreted as HFIP-glucuronide in the urine (HFIPu). Therefore the HFIP removal kinetics in occupational exposure and the correlation between sevoflurane exposure and HFIPu are poorly understood. We studied no. 86 operating room workers of Novara Hospital to evaluate the correlation between the sevoflurane individual exposure (SE) and the HFIPu at the end of the shift expressed in microgram/L (A-HFIPu) and in microgram/g creat. (C-HFIPu). Therefore, in the same group of subjects we evaluated the HFIPu in the urine sampled at 8.00 a.m. before the work. The correlation coefficient was R2 = 0.782 (p < 0.0001) for SE/A-HFIPu and R2 = 0.862 (p < 0.0001) for SE/C-HFIPu; HFIPu normalized for urinary creatinine (C-HFIPu) is an index more suitable than the A-HFIPu. Furthermore we concluded for the usefulness of pre-shift HFIPu.

RESUMEN

INTRODUCTION: The increasing demand for therapeutic monitoring in patients receiving antiplatelet therapy has been paralleled by the development of instruments and tests whose clinical usefulness is still under debate. We devised a laboratory approach to detect patients with antiplatelet resistance at risk to develop thrombotic events. METHODS: One hundred and eighty patients, under aspirin and clopidogrel after angioplasty and stent implantation, were studied by PFA100(®) with collagen/epinephrine (CoEPI, cutoff 165s) cartridge and by Multiplate(®) using arachidonic acid (ASPItest, pos < 862AUC), ADP (ADPtest, pos < 417AUC), and collagen (COLtest, pos < 607AUC). RESULTS: Only 67 of 173 patients with ASPI < 862 displayed a prolonged CoEPI and up to 65 patients had normal CoEPI despite ASPI < 300. Patients with ASPI < 300 had significantly lower COL than patients with ASPI > 300. One hundred and thirty-eight patients displaying ADP < 417 had significantly lower COL than those with ADP > 417. Association between COL and ADP remained after ASPI stratification: in patients with suboptimal (ASPI 300-892) or maximal (ASPI < 300) response to aspirin, having ADP < 417 (clopidogrel responsive) increased COL positivity, respectively, from 9.5 to 58.8% and from 47.6 to 82.7%. CONCLUSION: A combination of specific tests may be useful in identifying higher-risk patients with poor compliance or drug resistance who potentially may benefit from therapy change.
