Is micronutrients supplementation useful in pregnancy?

Use of micronutrients in pregnancy appears to be useful in prevention of some pregnancy related pathologies if used continuously before and during all nine months of pregnancy. The assumption of specific micronutrients, with vitamins and mineral salt inside, could be use to correct some deficiencies and prevent the onset of specific pregnancy related diseases. An adequate support of micronutrients can ensure physiological fetal growth contributing to the development of various fetal organs. Besides folic acid administered in appropriate doses (>400 mug), that it is able to prevent some fetal diseases, such as the closure of the neural tube, other vitamins such as vitamin A are very effective in ensuring an optimal state of health of the mother and slowing the growth of uterine myomas.     

Prognostic role of the recepteur d'origine nantais (RON) expression in ovarian cancer patients

ObjectiveThe aim of the study was to investigate the potential clinical relevance of immunohistochemically assessed RON expression in a large, single institution series of primary untreated advanced ovarian cancer patients.MethodsImmunohistochemical analysis was performed by using the polyclonal rabbit anti-RON-β antibody (C-20, clone sc-322, Santa Cruz, California). Results were expressed as the total proportion of immunostained tumor cells (RON positivity), or the percentage of cells showing strong staining of RON expression (H-RON positivity).ResultsIn the overall series RON positive immunoreaction was observed in 103/141 cases, while H-Ron positivity was detected in 577141 (40.4%) cases. No association between RON and H-RON expression with response to first-line treatment was documented. During the follow up period, progression and death of disease were observed in 111 (78.7%) and 76 (53.9%) cases, respectively. Cases with strong H-RON expression has a shorter overall survival (median = 35 months) than cases with low RON levels (median = 59 months) (X² = ? 2.1, p value = 0.032). In multivariate analysis, only platinum resistance, and extent of residual tumor retained an independent negative prognostic role for OS, with the percentages of H-RON positively immunostained cells showing a borderline statistical significance (p value = 0.0643). The unfavourable role of elevated percentages of H-RON expression was maintained only in the subgroup of platinum resistant recurrent ovarian cancer patients (X² = 3.89, p value = 0.048) compared to the platinum sensitive ones (X² = 1.98, p value = 0.16).ConclusionsThe assessment of RON expression deserves further attention as a parameter helpful to identify poor prognosis ovarian cancer patients potentially candidates to investigational agents.     

Antiproliferative oleanane saponins from Meryta denhamii

Eight new oleanane saponins (1- 8) together with four know saponins (9-12) were isolated from the aerial parts of Meryta denhamii. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The antiproliferative activity of all compounds was evaluated using three murine and human cancer cell lines: J774.A1, HEK-293, and WEHI-164.     

Continuity and change in the Mediterranean medical tradition: Ruta spp. (rutaceae) in Hippocratic medicine and present practices

ETHNOPHARMACOLOGICAL RELEVANCE: Ruta is a genus of Rutaceae family. It features mainly shrubby plants, native to the Mediterranean region and present in traditional medicine of this region since Antiquity. The three most diffused species Ruta chalepensis L., Ruta graveolens L., and Ruta montana (L.) L., are morphologically poorly differentiated and were probably interchangeably used during Antiquity. AIM OF THE STUDY: Hippocratic and contemporary medical applications of the Ruta genus in the Mediterranean were compared to check if they result from a continuity of use from the ancient times to nowadays. RESULTS: Ruta spp. was mainly employed in medical preparations by Hippocratic physicians as an abortifacient and emmenagogue. In addition to gynaecological conditions, in several treatises of the Corpus HippocraticumRuta spp. were also recommended as a specific remedy against pulmonary diseases. Ruta spp. leaves and also roots and seeds, were administered for internal use by Hippocratic physicians after having been soaked in wine or mixed with honey or its derivatives. Contemporary traditional uses of Ruta spp. have been assessed in detail in the whole Mediterranean area. CONCLUSION: Nowadays, Ruta spp. is used to treat different conditions but, as a general rule, the external uses are preferred as the toxicity of the plant is widely acknowledged.     

Quality of life and psychological distress in locally advanced cervical cancer patients administered pre-operative chemoradiotherapy

ObjectiveThe aim of the study was to analyze the Quality of life (QoL) scores in a single institution series of locally advanced cervical cancer patients (LACC) administered preoperative chemoradiation, compared to early stage disease (ECC) patients undergoing radical surgery.MethodsThe following criteria were required in order to enroll patients: age between 18 and 65years at initial diagnosis, at least 12months from the end of treatment, no evidence of recurrence/second malignancy. The SF-36 questionnaire on general health, and the HADS questionnaire on mental distress were utilized.Results93 subjects were available for the analysis. At time of analysis, median follow-up was 30months (range 12–120). LACC patients showed QoL scores comparable to ECC patients with the exception of physical functioning (mean ± SD = 69.0 ± 13.1 versus mean ± SD = 85.4 ± 16.2, p value = 0.0007). In the group of LACC patients, the presence of co-morbidities was significantly associated with the impairment of almost all subscales of QoL. A low education level and the status of unemployment were documented to negatively impact on the vast majority of SF-36 subscale scores. In the multivariate analysis, the presence of co-morbidities, low educational level, age> 50years, and unemployment maintained their independent negative association with poor QoL scores. The percentage of cases with high levels HADS-anxiety was higher in LACC than ECC patients (27.6% versus 8.6%, p value = 0.034).ConclusionsLACC patients administered preoperative chemoradiation showed QoL scores comparable to EEC patients, and a higher proportion of anxiety disorders; low educational level and unemployment status were mainly associated with poor QoL scores.     

Monochorionic and dichorionic twin pregnancies discordant for fetal anencephaly: a systematic review of prenatal management options

The aim of this study was to evaluate the effect of selective feticide (SF) compared to expectant management (EM) on perinatal outcome in dichorionic and monochorionic twins discordant for anencephaly. For this purpose, we conducted a systematic review of literature and added ten unpublished cases. As a result, we found that in dichorionic twins, mean gestational age (GA) at birth in the SF group was 38.0 weeks versus 34.9 weeks (P = 0.0002). Mean birth weight was 2922 g in the SF group versus 2474 g (P = 0.03). In monochorionic twins, mean GA at birth was 35.2 weeks versus 32.7 weeks (P = 0.1). Mean birth weight was 2711 g versus 1667 g (P = 0.0001).We conclude that while SF does not reduce perinatal mortality, it does result in significantly longer gestations and higher birth weight, and appears to be the management of choice in dichorionic twins discordant for anencephaly. In monochorionic twins, SF also increases birth weight, but in view of the complexity of this group, no clear recommendations can be made.     

Vaginal reconstructive surgery for severe pelvic organ prolapses: a 'uterine-sparing' technique using polypropylene prostheses

OBJECTIVE: The Ulmsten's "Integral Theory" for pelvic floor dysfunctions is based on the need to reinforce fascias and ligaments with prostheses to obtain a reconstitution of the pelvic floor's anatomy. In September 2004 we developed a "uterine-sparing" surgical technique to correct such pathologies and in this paper we present results obtained. Primary outcome was to evaluate the technique's efficacy, secondary outcomes the resolution of stress urinary incontinence, postoperative pain (VAS scale), safety and complications. STUDY DESIGN: This prospective study included patients affected by stage 3 and 4 uterine-vaginal prolapse who wished to conserve their uterus. Those with (1) minor degrees of severity, (2) unfit for surgery, (3) with a clear indication to hysterectomy (i.e. endometrial cancer), (4) with an elevated operative risk (American Society of Anaesthesiologists-ASA score III and IV), (5) previous vaginal surgeries and (6) with moderate/severe defecation problems were excluded. The technique consisted in a sacrospinous colposuspension with polypropylene mesh. The pelvic status was classified according to the international Pelvic Organ Prolapse staging system (POP-Q). Postoperative pain was scored with the VAS Scale. All patients were given the King's Health questionnaire, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Wexner questionnaire. RESULTS: From September 2004 to November 2006 we treated 80 patients. Polypropylene prostheses (Gynemesh-Soft PS, 10cmx15cm - GyneMesh, Gynecare Ethicon - Somerville, NJ, USA) were used to reconstruct the pubo-cervix or the recto-vaginal fascia. We performed an anterior-central vaginal reconstruction in 35 (43.8%) patients, central-posterior in 25 (31%) and total reconstruction in 20 (25%). The median follow-up was 21 months (range 18-26). The severe pelvic prolapse, evaluated with the POP-Q System, was completely treated in all the patients and no recurrences were observed. The urodynamic examination showed a complete resolution of the stress urinary incontinence in 10 patients (83%). Sexual activities improved in all patients. We recorded three vaginal erosions and one patient complained of a postoperative dyspareunia. CONCLUSIONS: This pilot study suggests that our technique is safe and effective and can efficiently repair the pelvic organs prolapse, without undergoing hysterectomy and with a low rate of vaginal erosions.
