Can trans resveratrol plus d-chiro-inositol and myo-inositol improve maternal metabolic profile in overweight pregnant patients?
Full text linkObjective. To investigate the effect of trans-resveratrol from Polygonum cuspidatum/magnesium hydroxide complex, trademark Revifast®, plus D-chiro-inositol (DCI) and Myo-inositol (MI) during spontaneous pregnancies in overweight patients in a pilot study. Study design. A one-year, prospective, randomized, doubleblinded, placebo-controlled single center clinical study was carried out on overweight pregnant women. 110 patients were randomized in 3 groups to receive: Revifast® with DCI/MI (group I), DCI/MI alone (group II) or control group (group III) for 30 and 60 days. The main outcomes were to explore the lipid profile (total cholesterol, LDL, HDL, TG) and glucose levels, after 30 and 60 days of therapy. Results. No difference in systolic and diastolic parameters among 3 groups during study. All blood chemistry parameters improved compared to placebo at 30 days already, but significantly to 60 days, respect placebo. By comparing the two treatment groups, group I demonstrates significantly improved lipid and glucose parameters than group II, which are at 30 to 60 days of treatment. Conclusion. The supplementation of Trans-resveratrol, Revifast® in addition to DCI/MI in overweight pregnant woman with an elevated fasting glucose improves glucose levels, Total Cholesterol, LDL and TG
The mRNA-HPV Test Utilization in the Follow Up of HPV Related Cervical Lesions
No full textAbstract: The biomolecular follow up of Human Papilloma Virus (HPV) is widely investigated in patients treated for HPV related cervical lesions, since the HPV-mRNA test is more specific and have a higher positive predictive value for CIN2-3 in triage of high risk (HR) women and in follow-up of women treated for CIN2/3.
Material & Methods: we investigated, during a 5 years’ study, a cohort of patients divided in: group 1, patients at high risk for HPV-infections, and group 2, women diagnosed for CIN2/3, Cervicocarcinoma in situ (CIS) and Adenocarcinoma in situ (AIS) and surgically treated. The overall scheduled follow up was repeated each 6 months by: Pap Test, HPV-DNA test, m-RNA-HPV test and, in case of CIN2/3, CIS and AIS, also by colposcopy and biopsy.
Results: The follow up involved a total of 203 women: 85 women with mRNA-HPV positive test and 118 patients surgically treated for CIN2/3, CIS and AIS. In the group 1, the long term follow up detected, after one year, 32 positive mRNA-HR HPV women and, of these, after more than 2 years, 37.5% developed CIN1 and 21.8% developed CIN2/3. Similarly, in the follow up of group two, women with abnormal Pap test showed positivity of mRNA HR-HPV in 71.4% of cases even after 6 months; 65% of these developed a CIN1 within 2.5 years and 20% had CIN2/3 after 2.3 years.
Conclusions: Study results indicate either that patients with mRNA HR-HPV positive controls, on average, after 12 months are all at risk of progression to CIN1 and CIN2/3, or the higher specificity of mRNA-HPV test than Pap Test in follow up of surgical treated patients. This investigation confirmed a strong association between HR mRNA-HPV presence and risk of neoplastic progression
The surgical outcome of intracapsular cesarean myomectomy. A match control study
No full textAuthors evaluated the outcome of intracapsular cesarean myomectomy by a prospective case-control study on 68 patients who underwent intracapsular cesarean myomectomy, compared with a control group of 72 patients with myomatosic pregnant uterus who underwent cesarean section (CS) without myomectomy. Mostly of removed myomas were subserous or intramural, fundal in 37 women (54.4%), corporal in 22 (32.3%) and peri-low uterine segment in 9 women (18.7%). The average myoma' size was 8cm (1.5-20), in 40 women, with 8 myomas measuring 4-6cm, 14 myomas between 10 and 12cm and >13cm in 6 patients. Difference in blood tests and surgical outcome in intracapsular cesarean myomectomy was non significant (p>0.05). The average duration of hospitalization of intracapsular cesarean myomectomies was 5 days. There was no correlation between complications or duration of hospital stay and patient age, gravidity, parity or indication for CS. The intracapsular cesarean myomectomy could be a reliable, feasible and safe obstetric procedure. Meticulous attention to gentle hemostasis, sharp pseudocapsule dissection, adequate approximation of the myometrium edges and all dead spaces to prevent hematoma formation, can further increase the safety of the procedure, without significant complications by experienced obstetricians. © 2014 Informa UK Ltd
Impact of surgical approach on blood loss during intracapsular myomectomy
No full textBackground: Myomectomy is one of the most common surgical procedures in gynecology and has implications on fertility and subsequent pregnancies. We compared the impact of surgical approach on blood loss during laparoscopic and abdominal intracapsular myomectomy. Material and methods: The evaluation comprised 124 fertile women with subserous or intramural myomas: 66 patients treated by laparoscopy and 58 patients treated by laparotomy. The intracapsular myoma enucleation technique was similar for both approaches. All procedures were analyzed for the evaluation of intra-and post-surgical blood loss and intra-and short-term post-operative surgical outcomes. Results: The operating time for laparoscopic intracapsular myomectomy was longer (95 ± 7.2 min vs. 63 ± 5.6, p < 0.0001), but was associated with reduced intra-(65 ± ml vs. 105 ± 5, p < 0.0001) and post-surgical blood loss (30 ± 5 vs. 60 ± 5 ml, p < 0.0001), as well as diminished application of pain relief medication (8 patients vs. 17, p < 0.05), compared to open intracapsular myomectomy. Conclusions: The surgical approach did not substantially affect the technique of intracapsular myomectomy; however, laparoscopy significantly reduced intra-and postoperative blood loss and resulted in better short-term outcomes than after open surgery. Our results underscore the advantages of trying to reduce the rate of laparotomic myomectomy, one of the leading surgical interventions associated with infertility and sterility. © 2014 Informa Healthcare
Lymphocele Prevention After Pelvic Laparoscopic Lymphadenectomy by a Collagen Patch Coated With Human Coagulation Factors: A Matched Case-Control Study.
No full textObjective: Lymphoceles are among the most common postoperative complications of pelvic lymphadenectomy (PL), with a reported incidence of 1% to 50%. Symptoms are pelvic pain, leg edema, gastrointestinal obstruction, obstructive uropathy, and deep vein thrombosis, and severe complications such as sepsis and lymphatic fistula formation. After laparoscopic PL, we tested the prevention of lymphoceles using collagen patch coated with the human coagulation factors (TachoSil) on 55 patients with endometrial cancer stages IB to II who had undergone laparoscopy.
Materials and Methods: The authors divided the patients into 2 laparoscopy groups: PL plus TachoSil (group 1: 26 patients) and PL without TachoSil in a control group (group 2: 29 patients), as historical cohort of patients who underwent PL between 2010 and 2012.
We collected surgical parameters, and the patients underwent ultrasound examination on postoperative days 7, 14, and 28. The main outcome measures were the development of symptomatic or asymptomatic lymphoceles, the need for further surgical intervention, as adverse effect of surgery, and the drainage volume and duration.
Results: The same number of lymph nodes in both groups was removed; group 1 showed a lower drainage volume. Lymphoceles developed in 5 patients in group 1 and in 15 patients in group 2; of these, only 2 patients were symptomatic in group 1 and 5 patients were symptomatic in group 2, without statistical difference and no percutaneous drainage request.
Conclusions: In this preliminary investigation, the intraoperative laparoscopy application of TachoSil seems to reduce the rate of postoperative lymphoceles after PL, providing a useful additional treatment option for reducing drainage volume and preventing Ls development after PL
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
