Chemical composition and volatile constituents of Anthyllis barba-jovis
No full textPhytochemical investigation of chloroformic and methanolic extracts from aerial parts of Anthyllis barba-jovis L. (Leguminosae) led to the characterization of six flavonol-glycosides: kaempferol-3-O--D-glucopyranoside, kaempferol-7-O--L-rhamnopyranoside, kaempferol-3-O--D-glucopyranoside-7-O--L-rhamnopyranoside, kaempferol-3-O--D-glucopyranosyl-(12)--L-rhamnopyranoside-7-O--L-rhamnopyranoside, quercetin-3-O--D-glucopyranoside, isorhamnetin-3-O--D-glucopyranoside-7-O--L-rhamnopyranoside were identified together with two coumarins and D-pinitol, a taxonomic marker of Leguminosae family. The structural elucidation of all compounds was based on their 1H and 13C-NMR spectral data, bidimensional experiments and confirmed by MS analysis. In order to complete the phytochemical investigation, the essential oils from flowers and seeds of A. barba-jovis were obtained by hydrodistillation and analyzed by GC/MS; fresh flowers were submitted also to Solid Phase Micro Extraction

No full textThree new cycloartane-triterpene glycosides, astraverrucin IV, V and VI, were isolated from the aerial parts of Astragalus verrucosus. Based on spectroscopic analysis (IR, 1D and 2D-NMR, FABMS), the structures of the saponins were established to be cycloastragenol 3-O-[α-L-rhamnopyranosyl(1 → 4)-β-D-glucopyranoside], cycloastragenol 3-0-[α-L-rhamnopyranosyl(1 → 4)]-β-D-(3-O-acetyl)glucopyranoside and cycloastragenol 3-O-[α-L- rhamnopyranosyl (1 → 4)]-β-D-(6-O-acetyl)-glucopyranoside. D-pinitol and astraverrucin I were also obtained
Chemical composition and volatile constituents of Anthyllis barba-jovis
No full textSix flavonol glycosides were isolated and identified from the aerial parts of Anthyllis barba-jovis L. (Leguminosae), together with two coumarins and D-pinitol, a taxonomic marker of Leguminosae family. The structural elucidation of all compounds was based on their (1)H- and (13)C-NMR spectral data and bidimensional experiments. The total flavonoid content was also determined, according to the method described in the Italian pharmacopoeia. In order to complete the phytochemical investigation on A. barba-jovis, the essential oils from flowers and seeds were obtained by hydrodistillation and analysed by GC-MS; fresh flowers were analysed also directly by solid phase micro extraction (SPME)
LA COPPETTA MESTRUALE: UNA VALIDA ALTERNATIVA AD ASSORBENTI E TAMPONI. DONNE E OSTETRICHE A CONFRONTO
No full textA menstrual cup is a cup or barrier worn inside the vagina to collect menstrual fluid, it is an alternative to pads and tampons and it was invented in the 30s, but only recently is spreading in Italy. Unlike sanitary napkin it is reusable and it can last up to 10 years, so that it is very economical and environmental friendly.
The aim of the study is to understand whether a menstrual cup may be a valid alternative to pads and tampons and evaluate if it is known among the midwives.
Two questionnaires have been developed: one for women and one for midwives.
The women’s one investigates the use of the menstrual cup, its comfort and efficiency, the presence of difficulties during insertion and removal; at last asks women who don’t use a menstrual cup if they would like to try it and if not requires a reason.
The midwives’ one investigates their knowledge about menstrual cups, so technical questions have been demanded and finally they were asked what kind of woman they would recommend it to.
1190 women have answered the questionnaire and the ones who use menstrual cups are overall satisfied, even if they had difficulties with insertion and removal at the beginning, and nearly all of them will keep on using it and would recommend it to other women. One half of the women who don’t use a menstrual cup would like to try it and the other half says they wouldn’t like it because they think it is unhygienic and uncomfortable.
514 midwives answered the questionnaire and most of them are aware about menstrual cups and their technical aspects; there is some gap about the existence of different models of menstrual cups, who is indicated for and about the cleaning.
To conclude a menstrual cup can be a valid alternative to pads and tampons and most of the midwives would recommend it to all woman or only to the ones who have confidence with their body, just a few midwives wouldn’t recommend a menstrual cup at all
La scelta delle madri di non allattare, studio epidemiologico presso la Clinica Mangiagalli
No full textNonostante i noti benefici del latte materno e dell’allattamento, alcune madri scelgono di non allattare al seno il proprio bambino, preferendo ad esso l’allattamento artificiale.
Studi internazionali hanno identificato i fattori che influenzano la decisione di allattare al seno; tuttavia, la scarsa conoscenza di questo fenomeno e la sociale considerazione “negativa” della madre che non allatta, hanno suscitato l’interesse per la realizzazione di questo studio.
Il campione studiato è rappresentato dalle donne che non hanno allattato al seno per scelta nella Clinica Mangiagalli di Milano, dal 10 maggio al 10 agosto 2011.
Lo studio si prepone di stimare la prevalenza del fenomeno in studio, osservare l’epidemiologia del fenomeno, individuare alcune delle motivazioni che spingono le donne a prendere questa scelta e considerare il coinvolgimento degli operatori sanitari, in particolare dell’ostetrica nella decisione delle donne di non allattare.
I dati sono stati raccolti tramite un questionario e un’intervista semistrutturata, somministrati individualmente a ciascuna donna coinvolta nello studio.
La prevalenza del campione è risultata del 3%. I fattori epidemiologici di cui si può ipotizzare un’associazione alla scelta di non allattare sono stati: la pluriparità, l’aver vissuto precedenti allattamenti difficoltosi, aver affrontato un taglio cesareo programmato, non aver frequentato alcun corso pre parto e la scarsa informazione sull’allattamento al seno. Le motivazioni personali più riportate dalle madri sono state: aver incontrato difficoltà con l’allattamento precedente, aver considerato l’allattamento artificiale il metodo più pratico, aver ricevuto suggerimenti dagli operatori sanitari e avere un’avversione personale all’allattamento materno.
I fattori psicologici, come l’avversione personale all’allattamento o il non essere state allattate dalle proprie madri, rimangono fenomeni poco conosciuti e pertanto meritano studi approfonditi. Si ipotizzano dei piani di assistenza per le donne in maternità, rivolti in particolare alle ostetriche, con lo scopo di garantire la miglior informazione sull’allattamento al seno e la sua promozione affinché le madri possano sostenere una scelta informata e consapevole

No full textL'ostetrica e lo spazio giovani nei consultori : analisi dei bisogni degli adolescenti e progetto di miglioramento dei servizi
No full textLo studio è stato condotto per comprendere il grado di conoscenza e il conseguente utilizzo da parte degli adolescenti degli Spazi Giovani istituiti all’interno dei consultori, strutture valide e da valorizzare, dove l’Ostetrica attua progetti di prevenzione e sostegno orientati alle diverse problematiche del mondo giovanile.
Dopo una verifica di quanto i servizi consultoriali sul territorio di Milano e Saronno offrono ai giovani, sono stati somministrati 225 questionari ad adolescenti di età compresa tra i 15 e 20 anni per verificare quale fosse la loro idea rispetto a questo servizio, quali i motivi dell’eventuale utilizzo e quali le aspettative rispetto ai loro bisogni.
Prendendo spunto dalle risposte fornite dai giovani e dal contatto con diversi progetti in atto, si evidenza una non conoscenza di questa realtà costruita ad hoc per loro, si riconosce il bisogno di intervenire e si formulano diverse proposte operative
EDUCAZIONE ALL’AFFETTIVITÀ E ALLA SESSUALITÀ: analisi delle conoscenze dei ragazzi delle scuole medie e ruolo educativo dell’ostetrica
No full textIntroduction - Many global organizations, including the WHO, declare the importance of emotional and sexual education for young people in schools and communities in order to ensure them a good sexual and reproductive health. Throughout Europe there is the need to make sex education a compulsory subject in both primary and secondary school, with minimum standards and educational objectives defined and shared, as in Germany, France, Netherlands and Sweden. In Italy, although the importance of emotional and sexual education is recognized, there has been no attempt to make this type of education compulsory in the schools, where education courses on these subjects are offered on a voluntary basis of individual schools and / or at the complete discretion of the teachers.
Purposes
The aim of this study is to verify knowledge that students have about sexuality after different school programs led them to participate in a course of emotional and sexual education either held by midwives, psychologists or not to participate to any course at all. Secondly, this study wants to understand whether courses led by different professionals deliver different contents and / or treat different topics.
Methods
250 boys and girls from the 7th and 8th grade middle school classes of three different schools in the city of Milan and Melegnano (MI) have been involved in the research. The students of the first school have attended classes held by two practicing midwives of the University of Milan. In the second school the course was conducted by psychologists, while in the third school there had been no course at all of emotional and sexual education during the academic year in 2013/2014. The data were collected during the months of May and June 2014 by administrating an anonymous multiple choice questionnaire.Results
All the students agree that it is necessary to speak of emotional and sexual education in school, since they believe that sexual education makes young people more aware and confident of their choices. However different sexual knowledge and attitudes among students of the three schools emerged. The students of the first school are much better prepared in anatomy and physiology of the male and female genital apparatus, in the use of contraception, pregnancy and abortion. The students of the first school also have scientific knowledge on sexuality, while students of the second and third school have vague and partly untrue beliefs about it.
Conclusions
It therefore appears that midwives can absolutely be considered the key figure in the field of emotional and sexual education. In fact midwives have the knowledge, qualities and skills that this delicate type of educational role requires. Midwives are health professionals and during meetings of emotional and sexual education in schools they promote sexual and reproductive health of adolescents giving them the tools to live a satisfying and aware sex life
