RESUMEN

PURPOSE: Resilience is conceptually characterized as a dynamic process encompassing positive adaptation in the context of significant adversity. Our goal was to assess the resilience in people with epilepsy (PWE) and how it impacts longitudinally on psychosocial factors, with a particular focus on the manifestation of stigmatization-related feelings. METHODS: We consecutively enrolled 78 adults PWE (42.5 ± 16.2 years old); among them 36 (46.1 %) were seizure-free. All subjects completed at baseline (T0) the Resilience Scale (RS-14) and questionnaires for the assessment of depressive symptoms, anxiety and quality of life: respectively, Beck Depression Inventory-II (BD-II), Generalized Anxiety Disorder-7 (GAD-7) and QOLIE-31 (Q31). All patients were followed up prospectively and re-evaluated after 6-22 months (T1; mean: 14 ± 8 months; median 14 months); at follow up they also completed the Stigma Scale of Epilepsy (SSE) for the assessment of the stigma associated with epilepsy. We correlated resilience values with all psychosocial scores at T0 and T1. Factors associated with resilient and vulnerable outcomes were identified. Finally, a multiple stepwise regression analysis was applied to identify predictors for resilience and stigma perception. RESULTS: The results showed for the RS-14 score a significant direct correlation with the Q31 (p < 0.001) and an inverse correlation with the depressive and anxiety symptoms at both times (T0 and T1), as evaluated with BDI-II (p < 0.001) and GAD-7 (p < 0.001). Finally, we found a significant inverse correlation between RS-14 at T0 and the levels of stigmatization assessed with SSE at T1 (p =.015). Using a multiple stepwise regression analysis separately for resilience and stigma perception, depressive symptoms turned out as the best predictors for both variables. Finally, considering longitudinal evaluation we did not observe significant changes in depressive and anxious symptoms, despite a significant reduction in the total number of seizures at follow up. CONCLUSIONS: Our study showed that depressive symptoms, anxiety and quality of life were significantly associated with resilience in PwE. Finally, as a novel finding resilience was proved to affect the perception of stigma related to epilepsy more than seizures.

RESUMEN

OBJECTIVES: Poor medication adherence in people with epilepsy (PwE) increases mortality, hospitalization, and poor quality of life, representing a critical challenge for clinicians. Several demographic, clinical, and neuropsychological factors were singularly found associated with medication adherence in several studies, but the literature lacks a comprehensive study simultaneously assessing all these variables. METHODS: We performed a multicenter and cross-sectional study using online questionnaires with the following clinical scales: Morisky Medication Adherence Scale (MMAS-8), Quality of Life in Epilepsy Inventory 31 (QoLIE-31), Beck Depression Inventory-II (BDI-II), Generalized Anxiety Disorder-7 (GAD-7) and 14-item Resilience scale (RES14) in a population of 200 PwE. We used the ANOVA test and Spearman's correlation to evaluate the relationship between medication adherence and demographic, clinical (seizure frequency, number of anti-seizure medications), and neuropsychological characteristics. We trained separate machine learning models (logistic regression, random forest, support vector machine) to classify patients with medium-high adherence (MMAS-8 ≥ 6) and poor adherence (MMAS-8 < 6) and to identify the main features that influence adherence. RESULTS: Women were more adherent to medication (p-value = 0.035). Morisky Medication Adherence Scale -8 showed a direct correlation with RES14 (p-value = 0.001) and age (p-value = 0.001), while was inversely correlated with BDI-II (p-value = 0.001) and GAD-7 (p-value = 0.001). In our model, the variables mostly predicting treatment adherence were QoLIE-31 subitems, followed by age, resilience, anxiety, years of school, and disease duration. CONCLUSION: Our study confirms that gender, age, and neuropsychological traits are relevant factors in predicting medication adherence to PwE. Furthermore, our data provided the first evidence that machine learning on multidimensional self-report questionnaires could help to develop a decisional support system in outpatient epilepsy clinics.

RESUMEN

BACKGROUND: Anxiety is one of the most relevant psychiatric comorbidities in people with epilepsy (PwE). The role of resilience (RES) in the development of anxiety is not well understood. We purposed to better characterize RES impact on anxiety severity in PwE. MATERIALS AND METHODS: One hundred and seventy-six PwE underwent online surveys including a collection of socio-demographic, seizure-related, and psychological variables. PwE were grouped according to the data collected; anxiety levels were compared through non-parametric statistics. Hierarchical regression analysis (HRA) and logistic regression were performed to characterize RES contribute in predicting the presence and the severity of anxiety. Mediation/moderation analysis was performed to evaluate causal effects among RES, depression, and anxiety. RESULTS: Anxiety did not differ according to socio-demographic and seizure-related variables, exemption for the presence of drug-related adverse effects. Depression, RES, and sleep quality provided the major contribute on anxiety variance. The addiction of RES level in HRA and logistic regression provided a significant increase of R-squared value (p-value = 0.02) and of area under the curve (p-value = 0.03), respectively. RES modulated depression/anxiety relationship (p-value < 0.001), whereas depression did not mediate RES/anxiety correlation (p-value = 0.68). CONCLUSIONS: We demonstrated that RES is a significant independent predictor of anxiety in PwE and is able to modulate depression impact on anxiety. Moreover, we confirmed the relevance of depression and sleep quality on anxiety severity.

RESUMEN

BACKGROUND: The outcomes of paraaortic lymphadenectomy were compared for the treatment of gynecological malignancies to identify the most appropriate surgical approach. METHODS: Our retrospective, multicentric study included 1304 patients who underwent paraaortic lymphadenectomy for gynecological malignancies. The patients were categorized into the following five groups based on treatment type: transperitoneal laparoscopy (group A, n = 198), extraperitoneal laparoscopy (group B, n = 681), robot-assisted transperitoneal laparoscopy (group C, n = 135), robot-assisted extraperitoneal laparoscopy (group D, n = 44), and laparotomy (group E, n = 246). RESULTS: The prevalence of cancer types differed according to the surgical approach: there were more ovarian cancers in group E and more cervical cancers in groups B and D (p < 0.001). Estimated blood loss was higher in group E (844.2 mL) than in groups treated with minimally invasive interventions (115.8-141.5 mL, p < 0.005). For infrarenal dissection, fewer nodes were removed in group C compared with the other approaches (16 vs. 21 nodes, respectively, p < 0.05). The average operative time ranged from 169 min for group A to 247 min for group E (p < 0.001). Length of hospital stay was 14 days for group E versus 3.5 days for minimally invasive procedures (p < 0.05). The early postoperative grade 3 and superior Dindo-Clavien complications occurred in 9-10% of the patients in groups B-D, 15% of the patients in group E, and only 3% and 4% for groups A and C, respectively. The most common complication was lymphocele. CONCLUSIONS: Laparotomy increases preoperative and postoperative morbidity. The robot-assisted transperitoneal approach demonstrated a poorer lymph node yield than laparotomy and extraperitoneal approaches.

RESUMEN

Immediate vaginal reconstruction is usually offered following pelvic exenteration for recurrent cervical cancer in women previously treated with radiotherapy or with severe radiation-induced fistulae. Introduction of muscle-sparing flaps, such as the pedicled vertical deep inferior epigastric perforator (DIEP) flap, provides viable tissues for vaginal reconstruction and is associated with reduced donor-site morbidity. This report describes the surgical technique, which is one of the procedures of choice for vaginal reconstruction. It is safe and beneficial, especially for women with gynecologic cancer who have undergone pelvic exenteration after failed radiation therapy.

RESUMEN

We present a unique matter-wave interferometer whose phase scales with the cube of the time the atom spends in the interferometer. Our scheme is based on a full-loop Stern-Gerlach interferometer incorporating four magnetic field gradient pulses to create a state-dependent force. In contrast to typical atom interferometers that make use of laser light for the splitting and recombination of the wave packets, this realization uses no light and can therefore serve as a high-precision surface probe at very close distances.

RESUMEN

BACKGROUND: Pelvic exenteration remains one of the most mutilating procedures, with important postoperative morbidity, an altered body image, and long-term physical and psychosocial concerns. This study aimed to assess quality of life (QOL) during the first year after pelvic exenteration for gynecologic malignancy performed with curative intent. METHODS: A French multicentric prospective study was performed by including patients who underwent pelvic exenteration. Quality of life by measurement of functional and symptom scales was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 (version 3.0) and the EORTC QLQ-OV28 questionnaires before surgery, at baseline, and 1, 3, 6, and 12 months after the procedure. RESULTS: The study enrolled 97 patients. Quality of life including physical, personal, fatigue, and anorexia reported in the QLQ-C30 was significantly reduced 1 month postoperatively and improved at least to baseline level 1 year after the procedure. Body image also was significantly reduced 1 month postoperatively. Global health, emotional, dyspnea, and anorexia items were significantly improved 1 year after surgery compared with baseline values. Unlike younger patients, elderly patients did not regain physical and social activities after pelvic exenteration. CONCLUSIONS: Therapeutic decision on performing a pelvic exenteration can have a severe and permanent impact on all aspects of patients' QOL. Deterioration of QOL was most significant during the first 3 months after surgery. Elderly patients were the only group of patients with permanent decreased physical and social function. Preoperative evaluation and postoperative follow-up evaluation should include health-related QOL instruments, counseling by a multidisciplinary team to cover all aspects concerning stoma care, sexual function, and long-term concerns after surgery.

RESUMEN

We realize beam splitters and mirrors for atom waves by employing a sequence of light pulses rather than individual ones. In this way we can tailor atom interferometers with improved sensitivity and accuracy. We demonstrate our method of composite pulses by creating a symmetric matter-wave interferometer which combines the advantages of conventional Bragg- and Raman-type concepts. This feature leads to an interferometer with a high immunity to technical noise allowing us to devise a large-area Sagnac gyroscope yielding a phase shift of 6.5 rad due to the Earth's rotation. With this device we achieve a rotation rate precision of 120 nrad s(-1) Hz(-1/2) and determine the Earth's rotation rate with a relative uncertainty of 1.2%.

RESUMEN

BACKGROUND: Chemoradiation therapy (CRT) has become the mainstay of locally advanced cervical carcinomas (LACC). However, the price to pay is a significant rate of both early and late colo-rectal toxicities, which may impact on survivors' quality of life. To reduce the incidence of such complications, we suggest a simple technique of pelvic radioprotection. MATERIALS AND METHODS: An omental flap is created which is placed to fill the Douglas pouch to both increase the space between rectum and uterine cervix and prevent small bowel to fall in and to be exposed to radiation. In addition, a long sigmoid loop is retracted and fixed in the left paracolic gutter to prevent its irradiation as well. RESULTS: From May 2011 to May 2012, 51 successive LACC patients were offered this procedure in addition of a laparoscopic staging. All but 2 with too small an omentum benefitted from omentoplasty, while sigmoidopexy was performed in all but one patient with a long and free sigmoid loop. No immediate adverse effect was observed. The volume of retro-uterine omental flap averaged 7.17 ± 3.79 cm(3). Sequential measurements of the utero-rectal space throughout CRT duration showed a real and durable increase in the distance between these organs, resulting in a drop in the dose of irradiation to recto-sigmoid. With 10 ± 4.5-month median follow-up, we did not observe any rectal or small bowel early or late adverse effects of CRT. CONCLUSIONS: Although this series is preliminary, this simple procedure, feasible by laparoscopy (or laparotomy), seems effective to prevent recto-sigmoid as well as small bowel from radio-induced complications due to pelvic CRT.

RESUMEN

OBJECTIVE: Catamenial epilepsy (CE) is defined as an increase in seizure frequency during specific phases of the menstrual cycle in women with epilepsy. The treatment usually includes a combination of non-hormonal and hormonal therapies. This systematic review summarizes the available data on the efficacy of progesterone and its derivates to treat CE. METHODS: We performed a systematic search of the literature to identify studies reporting data on the use of progesterone and its derivatives (any type and dose) for the treatment of CE. The main outcome included the efficacy of progesterone and its derivatives on seizure frequency. RESULTS: Nineteen articles (457 patients) were included; four were randomized controlled trials (two comparing progesterone vs placebo and two comparing norethisterone vs placebo). Progesterone was generally administered during the luteal phase (from day 15 to 25) or during perimenstrual exacerbations (from day 23 to 25), with an average dose of 10-30 mg/day to a maximum of 300 mg/day. The therapy, usually well tolerated, was ineffective in the randomized controlled trials; conversely, it was associated with an overall reduction in seizure frequency in case reports and uncontrolled studies. CONCLUSIONS: Although data from uncontrolled studies suggest that hormone therapy with progesterone may be useful in the treatment of CE, its efficacy has not been demonstrated in controlled trials. The possible antiseizure effect of progesterone could be mediated by its active metabolite allopregnanolone, making the plasmatic measurement of these hormones mandatory to evaluate efficacy. Further randomized controlled trials should investigate the efficacy of progesterone and its derivatives, addressing these pharmacological issues.

RESUMEN

PURPOSE: Patients with locally advanced cervical cancer (LACC) are usually treated with concurrent chemoradiotherapy. Extended-field chemoradiotherapy is indicated in case of para-aortic node involvement at initial assessment. 18-Fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18-FDG PET/CT) is currently considered to be the most accurate method of detection of node or distant metastases. The goal of this study was to evaluate the accuracy of PET at detecting para-aortic lymph node metastases in LACC patients with a negative morphological imaging. METHODS: Patients from five French institutions with LACC and both negative morphologic (magnetic resonance imaging, CT scan) and functional (PET or PET/CT) findings at the para-aortic level and distantly were submitted to a systematic infrarenal para-aortic node dissection either by laparoscopy or laparotomy. On the basis of pathological results, sensitivity, specificity, and positive and negative predictive values of PET/CT were assessed for para-aortic lymph node involvement. RESULTS: A total of 125 LACC patients (stage IB2-IVA disease with two local recurrences) fulfilled the inclusion criteria. All had an ilio-infrarenal para-aortic lymphadenectomy, either by laparoscopy (n = 117) or laparotomy (n = 8). Twenty-one patients (16.8%) had pathologically proven para-aortic metastases. Among them, 14 (66.7%) had negative PET/CT. Overall morbidity of surgery was 7.2%. All but one of the complications were mild and did not delay chemoradiotherapy. Sensitivity, specificity, and positive and negative predictive value of the PET/CT were 33.3, 94.2, 53.8, and 87.5%, respectively, for the detection of microscopic lymph node metastases. CONCLUSIONS: Laparoscopic staging surgery seems warranted in LACC patients with negative PET scan who are candidates for definitive concurrent chemoradiotherapy or exenteration.

RESUMEN

BACKGROUND: Ovarian cancer remains the most lethal gynecologic malignancy with high recurrence rates. Because recurrence involves primarily the peritoneum, intraperitoneal chemotherapy is being evaluated as a new approach to treat microscopic peritoneal disease. One trial showed that cisplatin-paclitaxel intraperitoneal chemotherapy with intravenous paclitaxel improved survival but increased morbidity. Another trial reported a significant improvement in overall survival (OS) and disease-free survival (DFS) without increasing the morbidity (P = 0.76) or mortality rates (hazard ratio 0.67, P = 0.02) after adding hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreduction. The current trial aims to evaluate the impact of adding HIPEC to primary or interval cytoreductive surgery for epithelial ovarian cancer (EOC) on the efficacy, safety, treatment feasibility, and quality of life. PATIENTS AND METHODS: This is an international, multicenter, open-label, randomized (1 : 1), two-arm, phase III clinical trial that will enroll 432 patients with newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage III EOC. Patients are randomized to receive or not HIPEC with the standard of care. Inclusion criteria include patients with FIGO stage III EOC, Fallopian tube carcinoma or primary peritoneal cancer who undergo complete primary or interval cytoreduction. The primary objective is to assess DFS of the addition of HIPEC. Secondary objectives are the assessment of OS, safety, return to intended oncologic treatment, quality of life and the trade-off between efficacy and morbidity. CONCLUSIONS: The results might help extend the indications of HIPEC to include patients undergoing primary cytoreduction, providing a standardized protocol for HIPEC in EOC management and reliable information on the quality of life after adding HIPEC.

RESUMEN

OBJECTIVE: To draw up recommendations on the use of prophylactic gynecologic procedures during surgery for other indications. DESIGN: A consensus panel of 19 experts was convened. A formal conflict of interest policy was established at the onset of the process and applied throughout. The entire study was performed independently without funding from pharmaceutical companies or medical device manufacturers. The panel applied the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system to evaluate the quality of evidence on which the recommendations were based. The authors were advised against making strong recommendations in the presence of low-quality evidence. Some recommendations were ungraded. METHODS: The panel studied 22 key questions on seven prophylactic procedures: 1) salpingectomy, 2) fimbriectomy, 3) salpingo-oophorectomy, 4) ablation of peritoneal endometriosis, 5) adhesiolysis, 6) endometrial excision or ablation, and 7) cervical ablation. RESULTS: The literature search and application of the GRADE system resulted in 34 recommendations. Six were supported by high-quality evidence (GRADE 1+/-) and 28 by low-quality evidence (GRADE 2+/-). Recommendations on two questions were left ungraded due to a lack of evidence in the literature. CONCLUSIONS: A high level of consensus was achieved among the experts regarding the use of prophylactic gynecologic procedures. The ensuing recommendations should result in improved current practice.

RESUMEN

OBJECTIVE: To estimate the incidence of clinically detected port-site metastases (PSM) in patients with endometrial and cervical cancer treated at two gynecologic oncology services with extensive experience. METHODS: All eligible uterine cancer patients laparoscopically staged at Centre Oscar Lambret in Lille and Institut Claudius Regaud in Toulouse, France, were reviewed. MEDLINE database was searched to identify articles on PSM after laparoscopic procedures for cervical and endometrial cancer. RESULTS: During the study period, 1216 laparoscopic procedures for uterine cancer were performed. 921 patients underwent laparoscopic staging for cervical cancer and 295 for endometrial cancer. The overall incidence of PSM in our institutions was 0.4% per procedure (5 patients), and the incidence of PSM after laparoscopy for cervical and endometrial cancer was 0.43% and 0.33%, respectively. Excluding patients with peritoneal carcinomatosis, the rate of port-site recurrence in our series lowered to 0.16%, and the rate of isolated PSM to 0%. The median time to the development of PSM was 8 months (range 6-48), the median overall survival from diagnosis for all patients was 26 months (range 7-30), and median survival from recurrence was 5 months (range 1-20). CONCLUSION: Although PSM is recognized as a complication of laparoscopy for ovarian cancer. PSM is a rare complication of laparoscopic staging for endometrial and cervical cancer. The majority of patients with PSM presented with associated synchronous disease. The incidence of isolated PSM can be maintained virtually to 0% by an adequate operative technique. We believe that PSM in patients with uterine cancer cannot be used as an argument against laparoscopic staging in uterine cancer.

RESUMEN

Many technologies based on cells containing alkali-metal atomic vapor benefit from the use of antirelaxation surface coatings in order to preserve atomic spin polarization. In particular, paraffin has been used for this purpose for several decades and has been demonstrated to allow an atom to experience up to 10 000 collisions with the walls of its container without depolarizing, but the details of its operation remain poorly understood. We apply modern surface and bulk techniques to the study of paraffin coatings in order to characterize the properties that enable the effective preservation of alkali spin polarization. These methods include Fourier transform infrared spectroscopy, differential scanning calorimetry, atomic force microscopy, near-edge x-ray absorption fine structure spectroscopy, and x-ray photoelectron spectroscopy. We also compare the light-induced atomic desorption yields of several different paraffin materials. Experimental results include the determination that crystallinity of the coating material is unnecessary, and the detection of C[Double Bond]C double bonds present within a particular class of effective paraffin coatings. Further study should lead to the development of more robust paraffin antirelaxation coatings, as well as the design and synthesis of new classes of coating materials.

RESUMEN

We demonstrate the possibility of dynamic imaging of magnetic fields using electromagnetically induced transparency in an atomic gas. As an experimental demonstration we employ an atomic Rb gas confined in a glass cell to image the transverse magnetic field created by a long straight wire. In this arrangement, which clearly reveals the essential effect, the field of view is about 2 x 2 mm(2) and the field detection uncertainty is 0.14 mG per 10 microm x 10 microm image pixel.

RESUMEN

Young women affected by a malignant tumor have to cope, after the announcement of diagnosis, with the treatment and its secondary effects. Indeed, some of them may definitively impact on their fertility potential. Especially in pelvic tumors, treatments are more or less mutilating, either by a direct surgical resection of pelvic organs or by destruction of their functioning after chemotherapy or radiation therapy. Surgeons are often at the front line in the management of gynecologic tumors. It is important for them to be aware not only of the surgical techniques currently available to preserve fertility, but as well of their indications and limits, according to the tumor type or its treatment. This knowledge will enable them to deliver fair information to the patient or couple, keeping in mind that, multidisciplinarity is of a paramount importance and referring a patient to a more experienced team, is sometimes the best solution. Through a literature review, we report on the most recent results of the different options available today according to cancer localization as well as some opinions concerning indications, management, organization of care, and teaching of these techniques.

RESUMEN

OBJECTIVE: To describe our early experience with robotic-assisted laparoscopy for extraperitoneal para-aortic lymphadenectomy up to the left renal vein, including Da Vinci robot positioning. METHODS: Six patients underwent robotic-assisted laparoscopy using the Da Vinci apparatus. The patients included a man with a pT2 non-seminomatous germ cell tumour of the left testicle treated by chemotherapy with an incomplete response (mature teratoma), four women with locally advanced cervical cancer, and one case of bulky cancer of the vaginal cuff. The procedure was carried out using four port sites: one for the camera, one each for the no. 1 and no. 3 arms of the Da Vinci robot system, and one for the assistant. RESULTS AND CONCLUSION: Robotic-assisted lymphadenectomy carried out using the Da Vinci system was safe and effective with a short learning period for an experienced oncological team. A larger prospective study is now required to evaluate this procedure further.

From the Automated Endoscopic System for Optimal Positioning (AESOP), a robotic arm which operates the laparoscope, to the robots Zeus and da Vinci, robotic assistance in gynaecological endoscopic surgery has continuously evolved for the last fifteen years or so. It has brought about new technical advancements: the last generation robots offer a steady three-dimensional image, improved instrument dexterity and precision, higher ergonomics and comfort for the surgeon. The da Vinci robotic system has been used without evincing any specific morbidity in various cases, notably for tubal reanastomosis, myomectomy, hysterectomy, pelvic and para-aortic lymphadenectomy or sacrocolpopexy amongst others. Robotic assistance in gynaecology is thus feasible. Like conventional laparoscopic surgery, it allows decreased blood loss and morbidity as well as shorter hospital stay, as compared to laparotomy. It might indeed allow many surgical teams to perform minimally invasive surgical procedures which they were not used to performing by laparoscopy. Randomized prospective studies are needed to define its indications more precisely. Besides, its medico-financial impact should be evaluated too.

RESUMEN

Debulking surgery is the key step of advanced stage ovarian cancer treatment with chemotherapy. The quality of surgical resection is the main prognosis factor, thus a complete resection must be achieved (grade A) in an expert center (grade B). Surgery for stage IV is possible and has a benefit in case of complete peritoneal resection (LoE3). Pelvic and aortic lymphadenectomies are recommended in case of clinical or radiological suspicious lymph nodes (grade B). In absence of clinical or radiological suspicious lymph nodes and in case of complete peritoneal resection during initial debulking surgery, lymphadenectomy can be omitted because it won't change nor medical treatment nor overall survival (grade B). Neoadjuvant chemotherapy can be proposed in case of: impossibility to perform initial complete surgical resection (grade B) ; alteration of general state or co-morbidities or elderly patient (in order to decrease morbidity and increase quality of life) (grade B); stage IV with multiple intra-hepatic or pulmonary metastasis or important ascites with miliary (grade B). In case of stage III or IV ovarian cancer diagnosed on a biopsy during prior laparotomy, a neoadjuvant chemotherapy and interval debulking surgery should be preferred (gradeC). In case of palliative surgery or peroperative impossibility to perform a complete resection, no data regarding the type of surgery to perform influencing survival or quality of life is available. Peritoneal carcinosis description before resection and residual disease at the end of the surgery should be reported (size, location and reason of non-extirpability) (grade B). A score of peritoneal carcinosis such as Peritoneal Carcinosis Index (PCI) should be used in order to objectively evaluate the tumoral burden (gradeC). A standardized operative report is recommended (gradeC).
