Pre-operational short-term forecasts for Mediterranean Sea biogeochemistry

Operational prediction of the marine environment is recognised as a fundamental research issue in Europe. We present a pre-operational implementation of a biogeochem- ical model for the pelagic waters of the Mediterranean Sea, developed within the framework of the MERSEA-IP Euro- pean project. The OPATM-BFM coupled model is the core of a fully automatic system that delivers weekly analyses and forecast maps for the Mediterranean Sea biogeochem- istry. The system has been working in its current configura- tion since April 2007 with successful execution of the fully automatic operational chain in 87% of the cases while in the remaining cases the runs were successfully accomplished af- ter operator intervention. A description of the system devel- oped and also a comparison of the model results with satel- lite data are presented, together with a measure of the model skill evaluated by means of seasonal target diagrams. Future studies will address the implementation of a data assimila- tion scheme for the biogeochemical compartment in order to increase the skill of the model’s performance

Health-related quality of life assessment in eating disorders: adjustment and validation of a specific scale with the inclusion of an interpersonal domain

Purpose: Quality of life is a fundamental aspect of both clinical practice and research on eating disorders (ED) due to the significant impacts these disorders have on everyday life. Disorder-specific scales can improve the quality of research and findings and offer greater sensitivity and responsiveness. However, no specific instrument is available in Italian for ED. The aim of this paper is to adjust and to validate a reliable scale with specific items regarding physical and interpersonal well-being. Methods: The Italian version of the Eating Disorder Quality of Life (IEDQOL) scale was developed, on the basis of the original English scale, with the addition of items pertaining to physical well-being and interpersonal interactions. In this study, 180 ED patients and 190 healthy controls from the community were enrolled both from inpatient units and outpatient services. A statistical analysis with an exploratory factorial approach was performed in order to validate the tool. Results: The results showed that the IEDQOL has very good psychometric properties with test–retest validity and sensitivity between patients and controls (d = 2.17 for total score). Moreover, the interpersonal domain showed excellent psychometric values (Cronbach’s α > 0.70 in all the subgroups) and a robust correlation with other quality of life constructs. Conclusion: Future studies on the Italian population should use IEDQOL as outcome element that can be useful also with other disorder-specific psychopathological constructs and corroborate the reliability of the data. Future research in the ED field should only use this specific tool. Level of evidence: Case–control analytic study, Level III

13q Deletion Syndrome Involving RB1: Characterization of a New Minimal Critical Region for Psychomotor Delay.

Retinoblastoma (RB) is an ocular tumor of the pediatric age caused by biallelic inactivation of the RB1 gene (13q14). About 10% of cases are due to gross-sized molecular deletions. The deletions can involve the surrounding genes delineating a contiguous gene syndrome characterized by RB, developmental anomalies, and peculiar facial dysmorphisms. Overlapping deletions previously found by traditional and/or molecular cytogenetic analysis allowed to define some critical regions for intellectual disability (ID) and multiple congenital anomalies, with key candidate genes. In the present study, using array-CGH, we characterized seven new patients with interstitial 13q deletion involving RB1. Among these cases, three patients with medium or large 13q deletions did not present psychomotor delay. This allowed defining a minimal critical region for ID that excludes the previously suggested candidate genes (HTR2A, NUFIP1, PCDH8, and PCDH17). The region contains 36 genes including NBEA, which emerged as the candidate gene associated with developmental delay. In addition, MAB21L1, DCLK1, EXOSC8, and SPART haploinsufficiency might contribute to the observed impaired neurodevelopmental phenotype. In conclusion, this study adds important novelties to the 13q deletion syndrome, although further studies are needed to better characterize the contribution of different genes and to understand how the haploinsufficiency of this region can determine ID. © 2021 by the authors.

A randomized controlled study comparing harmonic versus electrosurgery in laparoscopic myomectomy.

Abstract OBJECTIVE: To compare the effectiveness and safety of harmonic scalpel versus electrosurgery to reduce blood loss during laparoscopic myomectomy. DESIGN: Prospective randomized controlled study. SETTING: Tertiary referral centers for gynecological care. PATIENT(S): One hundred sixty consecutive premenopausal women with symptomatic uterine leiomyomata who were assigned to one of the two treatment groups (a total of 80 patients in each group): treatment with electrosurgery devices with a vasoconstrictive solution (50 mL of saline solution and 0.5 mL of epinephrine [1/2 vial of 1 mg/mL]; group A) or harmonic scalpel (group B). INTERVENTION(S): Laparoscopic myomectomy. MAIN OUTCOMES MEASURE(S): The global operative time, the time spent for myoma enucleation and for suturing uterine wall defects, and intraoperative blood loss as well as the surgical difficulty degree and postoperative pain at 24 and 48 hours after the laparoscopic procedure. RESULT(S): No relevant intra- or postoperative complications were observed in either group. The degree of pain 24 hours after surgery was significantly lower in patients in whom the harmonic scalpel was used. The degree of surgical difficulty did not differ between groups, but the global operative time was significantly shorter in the harmonic scalpel group. CONCLUSION(S): The use of the harmonic scalpel for laparoscopic myomectomy is associated with low total operative time, low intraoperative blood loss, and low postoperative pain, with no increase in surgical difficulty

Surgical scar endometriosis after Cesarean section: a case report

Background. Cutaneous endometriosis is a rare condition. Case report. A 37-year-old woman came to our observation 3 years after Cesarean section for a nodule under the scar that became spontaneously painful during menstrual bleeding. Transabdominal ultrasound examination, serum CA125 determination and histopathological analysis of the nodule were performed. Ultrasound revealed the presence of an oval-shaped hypoechogenic neoformation, while the serum CA125 level was slightly increased, and a diagnosis of endometriosis was confirmed by the histopathological analysis of a surgical specimen. Conclusion. This is an interesting case of surgical scar endometriosis, and the etiopathogenetic mechanism of this location may be explained by a dissemination of endometrial tissue during the Cesarean section. © 2006 Taylor & Francis

Maternal position during non-stress test and fetal heart rate patterns.

6Objective.  The aim of the study was to determinate whether maternal position during the non-stress test (NST) in different weeks of pregnancy influences fetal heart rate patterns. Materials and methods.  A total of 1055 NST lasting 30 min were performed in 368 autochthonous mothers with low-risk pregnancies. On the basis of maternal position during the test we divided into three groups: reclining, sitting, and walking. The cardiotocographic parameters considered were: number of minutes of reactive NST with minimum length, number of fetal movements, fetal heart rate baseline, number of large accelerations, number of dubious NST, and number of variable decelerations. Results.  Fetal heart rate patterns in low-risk pregnancies were studied using NST in different gestational ages and in different maternal positions. Differences in heart rate were found in relationship to both gestational age and maternal position. The minimum length of NST necessary to record at least three large accelerations was significantly different in relationship to both gestational age and maternal position. The number of fetal movements perceived by the mother was greater in the reclining position than in sitting or walking. Together with the progression of pregnancy, the number of dubious NST decreased in all subgroups, especially in the sitting position. The greatest number of variable decelerations was observed in the reclining position and it was increased with pregnancy progression. The NST duration did not vary greatly in the reclining position, but in the sitting position or during walking, the time taken to record the three large accelerations required to define the trace as reactive, decreased significantly with the progression of pregnancy Conclusions.  Non-stress test in sitting position or during walking should be encouraged because fetal reactivity is more quickly observed.reservedmixedCITO G; S.

Endometriosis: Treatment by local drug release systems

In the recent years, the research involved to clarify the mechanisms of endometriosis development opened new innovative treatments. In fact, not only new drugs have been studied but also new routes of administration for hormones have been investigated. The intrauterine and/or vaginal administration of progestins, such as levonorgestrel and danazol, seems to answer to some problems related to the long term management of endometriosis in terms of efficacy and compliance
