Amniotic fluid volume assessment has become standard in the surveillance of fetal well-being, especially in high-risk pregnancies. Amniotic fluid disorders are a frequent and important topic in fetal and perinatal medicine. However, although important advances have been achieved, many important and challenging questions remain unanswered to date. An abnormally low amniotic fluid volume, referred to as oligohydramnios, has been traditionally considered a possible indicator of placental insufficiency or fetal compromise and is associated with an increased rate of obstetric interventions. An excess of amniotic fluid, referred to as polyhydramnios, may be secondary to fetal or maternal conditions and has been associated with a variety of adverse pregnancy outcomes, especially when it is severe. The ultrasonographic detection of an amniotic fluid disorder should prompt a proper workup to identify the underlying etiology. Data on the association of isolated oligohydramnios or idiopathic polyhydramnios with adverse obstetric and perinatal outcomes are conflicting. While the management of secondary oligohydramnios is usually guided by the underlying condition, the management of isolated oligohydramnios is poorly defined. Similarly, the management of idiopathic and secondary polyhydramnios is not yet standardized. There is an urgent need for randomized clinical trials to provide stronger recommendations on the management of these two common conditions.

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) metabolize tryptophan in the kynurenine pathway. We evaluated these enzymes' mRNA expression in maternal and fetal sides of the placenta of uncomplicated, unlabored full-term pregnancies after elective cesarean section and compared it with that of placentas obtained from vaginal delivery. Tryptophan and kynurenine plasmatic levels after cesarean section were measured, to investigate their possible correlation with IDO1 and TDO mRNA (TDO2) expression. The results suggested that IDO1 and TDO2 expression was higher in the maternal side of the placenta and that labor significantly affects TDO2 expression and the plasma Kynurenine/Tryptophan ratio., Competing Interests: Conflict of Interest The author have no conflict of interest to disclose., (Copyright © 2023 Elsevier B.V.

The leading route of Chagas disease transmission in nonendemic countries is congenital. However, policies concerning screening, prevention, and management of congenital Chagas disease are rare in these settings. Since 2012, serological screening for Chagas disease should be provided for pregnant women at risk in Tuscany, Italy according to a Regional resolution. Due to difficulties in the implementation, in November 2019, a checklist aimed at identifying pregnant women at risk for Chagas disease was introduced in digital clinical records at Careggi University Hospital, Florence, Italy. In order to evaluate the effectiveness of the "Chagas checklist", data about the number of deliveries by women at risk and their screening coverage between 2012 and June 2022 were collected. Out of 1348 deliveries by women at risk, 626 (47%) Trypanosoma cruzi serology tests were performed during the study period. The annual screening coverage increased from an average of 40.3% between 2012 and 2019 to 75.7% between 2020 and June 2022, underlining the big impact of the checklist. Four Chagas disease serological tests out of 626 (0.6%) resulted positive, corresponding to 2 affected women. No cases of congenital transmission occurred. The study showed that a simple digital tool led to a tangible improvement in the coverage of the screening program; its application in a setting where digital charts are available will contribute to the control and elimination of congenital Chagas disease., Competing Interests: The authors declare no conflict of interest.

Ancient Roman concretes have survived millennia, but mechanistic insights into their durability remain an enigma. Here, we use a multiscale correlative elemental and chemical mapping approach to investigating relict lime clasts, a ubiquitous and conspicuous mineral component associated with ancient Roman mortars. Together, these analyses provide new insights into mortar preparation methodologies and provide evidence that the Romans employed hot mixing, using quicklime in conjunction with, or instead of, slaked lime, to create an environment where high surface area aggregate-scale lime clasts are retained within the mortar matrix. Inspired by these findings, we propose that these macroscopic inclusions might serve as critical sources of reactive calcium for long-term pore and crack-filling or post-pozzolanic reactivity within the cementitious constructs. The subsequent development and testing of modern lime clast-containing cementitious mixtures demonstrate their self-healing potential, thus paving the way for the development of more durable, resilient, and sustainable concrete formulations.

Background/aim: T2 weighted magnetic resonance (MR) imaging is the gold standard for locally advanced rectal cancer (LARC) staging. The potential benefit of functional imaging, as diffusion-weighted MR (DWI) and positron emission tomography-computed tomography (PET-CT), could be considered for treatment intensification strategies. Dose intensification resulted in better pathological complete response (pCR) rates. This study evaluated the inter-observer agreement between two radiation oncologists, and the difference in gross tumor volume (GTV) delineation in simulation-CT, T2-MR, DWI-MR, and PET-CT in patients with LARC., Patients and Methods: Two radiation oncologists prospectively delineated GTVs of 24 patients on simul-CT (CT GTV ), T2-weighted MR (T2 GTV ), echo planar b1000 DWI (DWI GTV ) and PET-CT (PET GTV ). Observers' agreement was assessed using Dice index. Kruskal-Wallis test assessed differences between methods., Results: Mean CT GTV , T2 GTV , DWI GTV , and PET GTV were 41.3±26.9 cc, 25.9±15.2 cc, 21±14.8 cc, and 37.7±27.7 cc for the first observer, and 42.2±27.9 cc, 27.6±16.9 cc, 19.9±14.9cc, and 34.8±24.3 cc for the second observer, respectively. Mean Dice index was 0.85 for CT GTV , 0.84 for T2 GTV , 0.82 for DWI GTV , and 0.89 for PET GTV , representative of almost perfect agreement. Kruskal-Wallis test showed a statistically significant difference between methods (p=0.009). Dunn test showed there were differences between DWI GTV vs. PET GTV (p=0.040) and DWI GTV vs. CT GTV (p=0.008)., Conclusion: DWI resulted in smaller volume delineation compared to CT, T2-MR, and PET-CT functional images. Almost perfect agreements were reported for each imaging modality between two observers. DWI-MR seems to remain the optimal strategy for boost volume delineation for dose escalation in patients with LARC., (Copyright © 2023, International Institute of Anticancer Research (Dr. George J.

In the past, the use of face masks in western countries was essentially limited to occupational health. Now, because of the COVID-19 pandemic, mask-wearing has been recommended as a public health intervention. As potential side effects and some contraindications are emerging, we reviewed the literature to assess the impact of them in daily life on patient safety and to provide appropriate guidelines and recommendations. We performed a systematic review of studies investigating physiological impact, safety, and risk of masks in predefined categories of patients, which have been published in peer-reviewed journals with no time and language restrictions. Given the heterogeneity of studies, results were analyzed thematically. We used PRISMA guidelines to report our findings. Wearing a N95 respirator is more associated with worse side effects than wearing a surgical mask with the following complications: breathing difficulties (reduced FiO 2 , SpO 2 , PaO 2 increased ETCO 2 , PaCO 2 ), psychiatric symptoms (panic attacks, anxiety) and skin reactions. These complications are related to the duration of use and/or disease severity. Difficulties in communication is another issue to be considered especially with young children, older person and people with hearing impairments. Even if benefits of wearing face masks exceed the discomfort, it is recommended to take an "air break" after 1-2 h consecutively of mask-wearing. However, well-designed prospective studies are needed. The COVID-19 pandemic could represent a unique opportunity for collecting large amount of real-world data., (© 2022.

Objective: To compare the ductus venosus (DV) pulsatility index for veins (PIV) obtained in a mid-sagittal plane with that obtained in an oblique transverse plane of the fetal abdomen., Methods: Prospective observational study in singleton uncomplicated pregnancies undergoing an ultrasound examination between 24 and 34 weeks of gestation. Pregnancies complicated by fetal anomalies, fetal growth restriction, or oligohydramnios were excluded. Two consecutive recordings of DV Doppler waveform were obtained in each woman: one in a mid-sagittal plane, and the other in an oblique transverse plane of the fetal abdomen. The peak velocity during ventricular systole (S-wave) and diastole (D-wave), the velocity during atrial contraction (a-wave), and the time-averaged maximum velocity (TAmax) were measured, and the PIV was calculated. The paired t -test was used to compare results obtained with the two approaches. A change of the DV-PIV of 0.10 or more was considered clinically relevant., Results: The DV waveform was successfully obtained in 53 women (mean gestational age 28.5 weeks). The mean DV-PIV was 0.57 (±0.16 SD ) in the sagittal plane and 0.54 (±0.16 SD ) in the transverse plane. The mean difference (0.03) was statistically significant ( p  = .04), but not clinically relevant. The sagittal S-, D-, and a-wave velocities and TAmax were significantly higher in the sagittal plane compared to the transverse plane, with an increase of 12, 8, 8, and 10%, respectively ( p  < .05)., Conclusions: The difference in the DV-PIV obtained in a mid-sagittal plane compared to a transverse plane of the fetal abdomen is small and not clinically significant. The higher DV flow velocities observed in the sagittal plane are likely the result of a better alignment with the vessel obtained using this plane. These findings have implications for clinical practice and for research.

Objective: To determine whether the effectiveness of cervical pessary is different in women who experienced cervical shortening after a threatened preterm labor episode compared to those with asymptomatic short cervix., Methods: Retrospective study on singleton pregnancies at risk for preterm delivery (PTD) due to cervical length <25 mm before 28 weeks, who were treated with Arabin cervical pessary. Two groups of patients were compared: those who had contractions causing shortening of the cervix, prior to pessary placement, and those who had asymptomatic cervical shortening. Patients carrying a multiple pregnancy and those who underwent iatrogenic PTD were excluded. The primary outcome was the incidence of PTD at different gestational ages. Secondary outcome was the rate of preterm premature rupture of membrane (pPROM). The groups were compared using univariate and multivariate analyses., Results: 115 patients that met the inclusion criteria were identified. Of these, 91 (79%) had asymptomatic cervical shortening, while 24 (21%) had an episode of threatened preterm labor that resolved, and the pessary was placed after the contractions had stopped. The two groups were similar for maternal characteristics, obstetric history, mean gestational age and length of the cervix at the time of pessary insertion. The median gestational age at delivery was significantly lower (36.4 vs 38.0 weeks, p  = .02), and the incidence of PTD significantly higher (58.3% vs 30.8%, OR 4.69, 95% CI 1.68-13.1, p  < .01) among women who had arrested preterm labor before the pessary was placed compared to the asymptomatic group, after controlling for confounders. The incidence of PTD before 34 and before 32 weeks was also significantly higher in the symptomatic group ( p  = .02 and p  = .005, respectively). Women with asymptomatic cervical shortening had a longer interval between the placement of the pessary and delivery (median 15 weeks). pPROM occurred with a similar incidence in both groups., Conclusions: Arabin cervical pessary to prevent preterm delivery seems be less effective in women with a short cervix following an episode of threatened preterm labor than in those with asymptomatic cervical shortening in the second trimester. This finding may help physicians to select patients in which cervical pessary is more likely to be effective, and to improve patient's counseling about this intervention.

Introduction: Placental dysfunction is one of the most common causes of Intrauterine Fetal Demise (IUFD). Due to its characteristics, the placenta may be the target of molecular research aimed to investigate potential causes of IUFD. In the literature, there are no studies on human placentas that have investigated possible associations between somatic mutations and the occurrence of IUFD. The aim of this study was to identify the presence of gene mutations in placental tissues in a series of cases of IUFD and to evaluate potential correlations with placental microscopic findings., Materials and Methods: Thirty-seven samples of formalin-fixed and paraffin-embedded placental tissues were retrospectively selected from pregnancies ending in IUFD between 23rd to 40th week. Six control placentas of physiological pregnancies were included as controls. After sampling, made according to standardized protocol and conventional histopathological examination, placental tissues were subjected to DNA extraction and sequencing by means of Next Generation Sequencing with a 56-gene panel., Results: The most frequent mutation observed in 32/37 IUFD cases (86.5%) and absent in any of the 6 control placentas was in c-KIT gene, which is implicated in placental tissue differentiation. However, no significant correlation was found between the presence of individual gene mutations and placental histopatological findings., Discussion: As the present study found an elevated frequency of c-KIT mutation in IUFD, it further supports the hypothesis that c-KIT is involved in abnormal tissue differentiation leading to altered placental vascularization and function., Competing Interests: Declaration of competing interest The authors certify that they have no affiliations with or involvement in any organization or entity with any financial interest or non-financial interest in the subject matter or materials discussed in this manuscript., (Copyright © 2022 Elsevier Ltd.

Background: Idiopathic polyhydramnios is a controversial clinical condition, as data on perinatal outcomes are conflicting and vary depending on the severity of the condition. The aim of the present study was to compare obstetric and neonatal outcomes between pregnant women with mild idiopathic polyhydramnios and a control population. Methods : A retrospective cohort study was performed at a single university hospital comparing the obstetrics and neonatal outcomes of pregnancies with mild idiopathic polyhydramnios ( n = 109) and control pregnancies ( n = 2550). Results : Cesarean section (CS) was significantly increased in the group with polyhydramnios compared to controls (46% vs. 32%, respectively, p = 0.047) due to a higher rate of emergency CS in the polyhydramnios group ( p = 0.041) because of abnormal cardiotocography (7.3% vs. 2.9%; p = 0.018) or labor dystocia (8.2% vs. 2.9%; p = 0.006). No statistically significant difference was found in the Apgar score, in the rate of neonatal hypoxia, or in the incidence of macrosomia between groups. In four cases, additional diagnoses of anomalies were made after birth, with a rate of 3.2%, which is comparable to the general population. Conclusion : Besides an increased risk of CS, patients with mild idiopathic polyhydramnios should be reassured regarding maternal and feto-neonatal outcomes. The management of pregnancies with stable mild idiopathic polyhydramnios should not differ from uncomplicated pregnancies, except for the need for increased labor surveillance.

Objective: To establish pregnancy-specific reference ranges for fasting and postprandial total serum bile acid (TSBA) concentrations., Design: Cross-sectional study., Setting: Tertiary-care university hospital., Population: Healthy pregnant women at term admitted to the Obstetrics Department over a period of 1 year. Exclusion criteria were an established diagnosis of intrahepatic cholestasis of pregnancy (ICP) or any coexisting condition of increased risk for ICP., Methods: Both fasting (after 8-14 h of fasting) and postprandial (2 h after meal) TSBA concentrations were measured in 612 women (with 528 fasting samples and 377 postprandial samples) by automated enzymatic spectrophotometric assay., Main Outcome Measures: Fasting and postprandial TSBA concentrations in 612 women., Results: Reference intervals of 4.4-14.1 μmol/L for fasting TSBA and 4.7-20.2 μmol/L for postprandial TSBA were established. The postprandial values were significantly higher than the fasting values, with a median increase of 1.0 μmol/L (p < 0.0001). A correlation between fasting TSBA concentrations and postprandial concentrations was found, as well as correlations with fetal sex, parity and assisted reproductive technologies. A seasonal pattern was noticed for both fasting and postprandial TSBA, with the highest values measured in the winter season (p < 0.01 and 0.02, respectively) CONCLUSIONS: Normal pregnancy is associated with mild hypercholanaemia, and therefore a higher threshold should be considered for the diagnosis of ICP. We suggest using the upper reference limits observed in our healthy pregnant population (14 μmol/L for fasting TSBA and 20 μmol/L for postprandial TSBA). As the fasting measurement is more specific for the diagnosis, and the postprandial measurement is essential for the assessment of severity, it is recommended to measure both values rather than use random sampling., Tweetable Abstract: Normal pregnancy is associated with mild hypercholanaemia, a higher threshold should be considered for the diagnosis of ICP., (© 2022 The Authors.

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are key enzymes for tryptophan degradation, regulating immune tolerance during pregnancy. The intrauterine renin-angiotensin system is also involved in the progression of a healthy pregnancy. Angiotensin(1-7) maintains the integrity of fetal membranes via counteracting the pro-inflammatory actions of Angiotensin II. No data are available on placental Angiotensin(1-7) co-expression with TDO. We aimed to characterize TDO mRNA expression and its localization in different areas of the placenta of physiological pregnancies delivered at term; its co-expression with Angiotensin(1-7) and its correlation with the plasma kynurenine/tryptophan (Kyn/Trp) ratio was investigated. This prospective observational study included a nonconsecutive series of 20 singleton uncomplicated pregnancies delivered vaginally. TDO mRNA was expressed in both maternal and fetal sides of the placentas and TDO protein also in the villi and it was co-expressed with IDO1 in almost half of the placental cells at these sites. The percentage of TDO + and IDO1 + cells appeared to be influenced by maternal pre-gestational smoking and newborn weight. A strong correlation was found between the percentage of TDO + and IDO1 + cells in the villi. TDO + cells also expressed Angiotensin(1-7), with a higher percentage on the fetal side and in the villi compared to the maternal one. Kyn/Trp plasma ratio was not correlated with IDO and TDO expression nor with the patient's characteristics. Collectively, our data indicate that TDO is detectable in placental tissue and is co-expressed with IDO and with Angiotensin(1-7) + on the fetal side and in the villi., Competing Interests: Decleration of Competing Interest The authors report no conflict of interest., (Copyright © 2022 Elsevier B.V.

Background: We report a mono-institutional experience regarding patient-perceived quality regarding the Chieti Radiotherapy Department, through RAMSI (Radiotherapy Amica Mia-SmileIN TM(SI) -My Friend Radiotherapy SI ) project, in critical scenarios of limited equipment and COVID-19., Material and Methods: Patient-reported experience measures (PREMs) were assessed as follows: Patient-centric welcome perception (PCWP), Comfort, Professional skills and Punctuality. Patients could give anonymous feedback using HappyOrNot technology through four totems located in strategic areas within the center. An internal benchmark was obtained using the feedback received after a preliminary observation period. The SI Experience Index was collected, analyzed and compared. Weekly and monthly reports were generated., Results: From February 2019 to February 2022, 8924 patients accessed the department; 17,464 daily treatments were recorded and 5830 points of feedback were collected: 896, 1267, 1125 and 2542 for PCWP, Comfort, Professional skills and Punctuality, respectively. A LINAC decommissioning period was analyzed, with decreases in the SI-Index score and Smile-IN approved percentage and an improvement after this period. Additionally, the COVID-19 pandemic was analyzed with a mild evaluations decrease for PREM's Welcome, Comfort and Punctuality (Δ-value: -9%, -3% and -4%, respectively), while Professional skills were always optimal., Conclusion: The RAMSI project was effective for assessing treatment quality perception, allowing for improving clinical procedures with corrective actions. The RAMSI project is ongoing.

In Italy, the paper package leaflet (PPL) is the official document that is approved by the Italian Medicines Agency (AIFA) for each medicine. PPLs of all medicines, including vaccines, are freely available online by accessing the AIFA website. To investigate people's attitudes toward possible access to the PPLs of vaccines and the acceptability of switching to an electronic package leaflet (e-leaflet) in the future, we surveyed three target groups (pregnant women, young parents, and older people) in Italy, via an online survey. We collected 321 questionnaires from the cohorts, which comprised 104 pregnant women, 105 young parents, and 112 older people. The results indicate in all target groups that health care professionals (HCPs) do not usually offer the vaccine PPL during the vaccination session: only about 10.7% of respondents receive the PPL without asking for it, with pregnant women receiving it the most frequently. The acceptance rate for switching from a PPL to an e-leaflet is fairly high in all target groups (76.9% in pregnant women, 81.9% in young parents, and 66.1% in the elderly), especially if the option exists to request a paper print, to make sure that people with a low level of digital skills can access the PPL information as well. HCPs have an important role in ensuring access to the PPLs of vaccines. HCPs should be trained to inform their patients about the different options for accessing the PPLs (as well as online access) to increase their patients' knowledge and satisfaction.

Purpose: Axillary management remains unclear when sentinel lymph node (SLN) results are positive in cN0 patients with breast cancer (BC). The trial ACOSOG Z0011 represented a revolution with axillary lymph node dissection (ALND) omission in SLN+ patients, despite critiques regarding non-uniformity of radiation fields. We conducted an observational study (LISEN) where whole breast radiotherapy (WBRT) was planned with tangential fields without nodal irradiation in patients eligible for the Z0011 trial., Methods: Inclusion criteria were female patients with histologically proven BC, cT1-2cN0, planned conservative surgery, no neoadjuvant therapy. Patients were stratified into two groups: micrometastatic (pN1mic, group 1) and macrometastatic (pN1a, group 2) lymph nodes. Tangential field WBRT was mandatory. Clinical outcomes were analysed, measured from surgery until the first event., Results: In all, 199 patients underwent conservative surgery and SLN biopsy; 133 patients meeting criteria were analysed: 41 patients (30.8%) pN1mic and 92 (69.2%) pN1a. The 5‑year disease-free survival (DFS) was 95.0% (85.9-100%) in group 1 and 93.0% (86.3-100.0%) in group 2 (p = 0.78). Overall survival (OS) was 100% (100-100%) in group 1 and 97.4% (92.4-100%) in group 2 (p = 0.74). For the whole cohort DFS and OS were 93.6% (88.2-99.4%) and 96.9% (91.5-100.0%), respectively. For groups 1 and 2, the 5‑year outcomes were 5.0% (0.0-14.4%) and 2.3% (0.0-6.1%) for local recurrence (p = 0.51), and 6.2% (0.0-17.4%) and 7.0% (0.0-13.7%) for distant metastasis (p = 0.61), respectively. In group 1, regional recurrence (RR) and local regional recurrence (LRR) were 5.0% (0.0-14.1%; p = 0.13). In group 2, RR and LRR were 0.0% (0.0-0.0%)., Conclusion: Our results showed good regional control in patients who met the Z0011 trial criteria. WBRT, without nodal surgery or RT, avoiding axillary morbidity, seems to be a good choice., (© 2022. The Author(s).)

Background: Admission in the latent phase of labor has been associated with increased risk of obstetric interventions compared to admission in the active phase. We aimed to investigate the relationship between labor phase at admission and obstetric and neonatal outcomes. Methods: A retrospective cohort study was conducted on 1005 women with uncomplicated singleton pregnancy admitted for spontaneous labor. Cesarean section rate and other perinatal outcomes were compared between women admitted in the latent phase and those admitted in the active phase. Results: Admission occurred in the active phase of labor for 331 women (32.9%) and in the latent phase for 674 (67.1%). Admission in the latent phase was more frequent in nulliparous than in multiparous (p < 0.01) and for Italian patients compared to foreigners. The incidence of caesarean section was similar between groups. Admission in the latent phase increased the likelihood of epidural analgesia (OR 3.47, 95% CI 1.96−6.14, in nulliparous, and OR 2.58, 95% CI 1.37−4.84, in multiparous) and increased the rate of augmentation of labor with oxytocin in multiparous (OR 2.87, 95% CI 1.05−7.85), without difference in neonatal outcomes. Conclusions: Admission in the latent phase is associated with more frequent use of epidural analgesia, without an increase in cesarean section or adverse neonatal outcomes.

The placement of peripheral intravenous catheters (PIVC) is potentially associated with complications that negatively impact healthcare. Our study investigated factors associated with the occurrence of PIVC-related complications in dogs and cats at a Veterinary Teaching Hospital. The second aim was to determine the prevalence of PIVC bacterial colonization. A total of 76 dogs and 40 cats with PIVCs were evaluated for the occurrence of phlebitis and mechanical complications. The devices were removed when they ceased to be functional or when complications occurred, and the content was submitted for bacterial cultures and antimicrobial susceptibility tests. Both multivariable linear regression models and ROC analysis were employed. Complications were recorded in 46.6% of cases, and 20.7% of catheters yielded a positive culture. Among the isolates, 45% were classified as multi-resistant. In dogs, a ≥36-h indwelling time was associated with an increased risk of complications. Male cats seem more prone to developing complications, while the insertion of PIVCs under sedation may represent a protective factor in this species. In conclusion, PIVC-associated complications were frequently observed, and the high rate of positive culture for PIVCs, together with the presence of multi-resistant isolates, is a cause of concern in a hospital setting.

Cytauxzoonosis is an emerging disease caused by a tick-transmitted haemoprotozoan affecting domestic and wild felids. The clinical and biomolecular findings of the infection due to Cytauxzoon sp. and concomitant coinfections are described in three cats in central Italy. Three domestic cats were referred for different clinical conditions (impact trauma, lameness, and weight loss and lethargy). They presented different hematobiochemical profiles. Only two cats were anemic, but in all three cats, endo erythrocyte inclusions suggestive of piroplasmids were found at blood smear evaluation. EDTA blood samples were submitted to rapid ELISA test for feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV), and to biomolecular investigations for Piroplasmida ( Babesia spp., Theileria spp., Cytauxzoon spp.) and Mycoplasma spp. All three cats were positive for Cytauxzoon sp. (European Cytauxzoon species) and two cases were also coinfected by Candidatus Mycoplasma turicensis and FIV. This report suggests that cytauxzoonosis should be included among differential diagnoses in subjects with possibility of contact with ticks and with presence of coinfections by tick-borne parasites, including in non-endemic areas.

Introduction: The cervical pessary is used in women with precocious cervical ripening to prevent preterm birth. Up to now however, there have been no systematic studies on compliance and tolerance, which vary among different study cohorts., Material and Methods: A questionnaire was administered to 166 women treated with the Arabin cervical pessary in one center. Data were analysed about the patient's experience before insertion (adequacy of information received), during treatment (follow-up, impact on daily life, perceived discomfort, side effects) and at the time of removal (pain, if the patient's expectations had been met regarding the treatment)., Results: Information received before the insertion of the Arabin cervical pessary was considered adequate in 163/166 (98.2%) women. An increase in vaginal discharge was experienced by 70/166 (42.2%) women. Discomfort or other side effects were reported in 13.8% and 16.3% of cases, respectively. Overall, 77% of women reported an improved quality of life and 94% considered the follow-up during pregnancy adequate. Removal was moderately painful for 58/166 (35%) of women. Patient's expectations regarding the treatment were exceeded in the majority of cases (75.3%). In a final step, we compared our results to previous studies regarding the use of the pessary in singleton and twin pregnancies., Conclusion: Although some trials report high rates of non-compliant patients, this could not be confirmed by our study. In contrast, most women reported having a positive experience and that they were motivated to continue the treatment when they were continuously followed by experienced clinicians., Competing Interests: The authors have declared that no competing interests exist.

Canine chronic enteropathies (CEs) are inflammatory processes resulting from complex interplay between the mucosal immune system, intestinal microbiome, and dietary components in susceptible dogs. Fatty acids (FAs) play important roles in the regulation of physiologic and metabolic pathways and their role in inflammation seems to be dual, as they exhibit pro-inflammatory and anti-inflammatory functions. Analysis of red blood cell (RBC) membrane fatty acid profile represents a tool for assessing the quantity and quality of structural and functional molecular components. This study was aimed at comparing the FA membrane profile, determined by Gas Chromatography and relevant lipid parameter of 48 CE dogs compared with 68 healthy dogs. In CE patients, the levels of stearic ( p < 0.0001), dihomo-gamma-linolenic, eicosapentaenoic ( p = 0.02), and docosahexaenoic ( p = 0.02) acids were significantly higher, and those of palmitic ( p < 0.0001) and linoleic ( p = 0.0006) acids were significantly lower. Non-responder dogs presented higher percentages of vaccenic acid ( p = 0.007), compared to those of dogs that responded to diagnostic trials. These results suggest that lipidomic status may reflect the "gut health", and the non-invasive analysis of RBC membrane might have the potential to become a candidate biomarker in the evaluation of dogs affected by CE.

The placenta represents the maternal-fetal vascular interface. It is capable of supplying the bioenergetic needs of the developing conceptus. It is composed of different cell types that engage in highly varied functions, ranging from attachment, invasion and vascular remodeling to cell fusion, hormone production, and nutrient transport. A deep knowledge of the immunological mechanisms responsible for maintaining an active tolerance towards an allogeneic fetus and the anti-inflammatory properties of the placenta can be useful to clarify the pathogenesis of adverse events in pregnancy. While the systemic mechanisms of this immunological regulation in pregnancy have been well studied, the metabolic processes involved in the placental immune response are still poorly understood. The aim of this review is to summarize the most important information concerning the immune regulation in pregnancy, focusing on the role of tryptophan (Trp) catabolism performed by indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO) in the placenta., (Copyright © 2021 Elsevier B.V.

Background: Rhizomelic chondrodysplasia punctata (RCDP) is a clinical entity resulting from defects of peroxisomal metabolism whose clinical phenotype is characterized by rhizomelia, calcified foci in periarticular cartilage, coronal lesions of vertebral bodies, cataracts and severe cognitive delay. Usually, survival does not exceed the first decade of life. Transmission is autosomal recessive and is related to mutations in the PEX7, GNPAT or AGPS., Methods: A detailed description of the prenatal ultrasound signs of RCDP found in two successive pregnancies in a consanguineous couple is reported. Molecular genetic investigations included the study of the coding regions and the exon-intron junctions of the GNPAT (high-throughput amplification and sequencing performed with Roche NimbleGen SeqCap Target kit on Illumina platform); the confirmation test was carried out by amplification and Sanger sequencing with automatic capillary sequencer., Results: In addition to the typical prenatal ultrasound signs described in the literature in association with RCDP, the presence of prefrontal oedema, never previously described, has been detected in both pregnancies. Moreover, genetic investigations have found a new splicing variant c.924+1G>A of the homozygous GNPAT., Conclusion: The role of mutation in the GNPAT suggests a likely association with the clinical phenotype., (© 2021 The Authors.

Objective: Expectant management in patients with prelabor preterm rupture of membranes between between 34 0/7 and 36 6/7 weeks (late preterm pPROM or LpPROM) has been shown to decrease the burden of prematurity, when compared to immediate delivery. As the severity of prematurity depends on gestational age (GA) at PROM, and PROM to delivery interval, we first investigated how such variables affect neonatal outcomes (NO). Second, we assessed the risk of neonatal sepsis., Study Design: retrospective cohort study on neonatal morbidity among singleton infants born to expectantly managed mothers with LpPROM in five hospitals affiliated with three Italian academic institutions. The primary NO was a composite of neonatal death, non-invasive (cPAP) or invasive (mechanical ventilation) respiratory support, hypoglycemia (< 44 mg/dl needing therapy), newborn sepsis, confirmed seizures, stroke, intraventricular hemorrhage (IVH), basal nuclei anomalies, cardiopulmonary resuscitation, umbilical-cord-blood arterial pH < 7.0 or base excess < -12.5, and prolonged hospitalization (≥ 5 days). Univariate analysis described differences in the population according to GA at delivery. Multivariate logistic regression was then used to investigate the effects of GA at PROM, and PROM to delivery interval on the NO., Results: 258/606 (42.6 %) women with LpPROM were expectantly managed, as they did not deliver within the first 24 h. The median latency duration was 2 (95 %CI 1-3) days, having no effect on neonatal morbidity on multivariate analysis. Multivariate analysis also showed increased risks of adverse NO among PROM at 34 (OR 2.3 95 %CI 1.03-5.1) but not at 35 weeks when compared to 36 weeks, and among women receiving antenatal corticosteroids (OR 3.6 95 %CI 1.3-9.7), while antibiotic treatment showed a non-significant protective effect (OR 0.2 95 %CI 0.04-1.02). Prevalence of neonatal sepsis was 0.8 % (2/258) CONCLUSION: Expectant management of LpPROM should be encouraged especially between 34 +0 and 34 +6 weeks', when the burden of prematurity is the greatest. Antibiotics may have beneficial effects, while careful consideration should be given to antenatal corticosteroids until future studies specifically address LpPROM., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2021 Elsevier B.V.

Pregnancy is a delicate phase in woman's life that could become a risk factor for osteoporosis in pregnant women who do not meet recommended nutrient standards, especially for calcium and vitamin D. Mediterranean diet (MD) has been demonstrated to be beneficial for adequate nutrient intake. This article aims to evaluate the MD adherence and dietary calcium intake in a group of pregnant Italian women and to investigate how these are linked to each other and to fast glycemia at first trimester of pregnancy. Two hundred and seventy-nine pregnant women were recruited at the gynecology units of two hospitals in Florence. Socio-demographic, clinical information, and results of the first trimester blood sample analysis were collected. Two questionnaires, validated for evaluation of MD adherence and calcium intake, were administered to the pregnant women. Approximately 60% of the women had a high level of MD adherence, with a mean dietary calcium intake of 870.3 ± 335.3. In women with higher MD adherence level, fast glycemia resulted lower. Calcium intake was lower than Population Rate Intake for the Italian population (1,200 mg/daily) and was positively correlated to MD adherence score. The MD proved to be nutritious, as it was related to a higher calcium intake in this group of Italian women., Competing Interests: B.P., S.Q., G.G., and F.G.: None.

Background/aim: Quality of life (QoL) in early breast cancer (BC) treatment may be affected by acute and late toxicities. This study evaluated the impact of radiotherapy (RT) schedules, treatment-related toxicities, hormone therapy (HT) and age on QoL., Patients and Methods: Ninety-five patients answered the FACT-B 4.0 questionnaire. Acute or late toxicities were recorded at each follow-up visit., Results: The median trend of the QoL subscales was stable during all questionnaires. HT negatively impacted on Functional Assessment of Cancer Therapy-General-Total, functional and emotional wellbeing. No difference was recorded between RT schedules and toxicity. No significant differences for age were detected in QoL., Conclusion: RT seems not to influence QoL of BC patients, in terms of fractionation regimen or RT-related side-effects. Moreover, women having systemic HT experienced a QoL worse than patients treated with RT only. Further and long-term protocols are needed to improve the validity of the tool., (Copyright© 2021, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Background/aim: The aim of the study was to investigate boost volume definition, doses, and delivery techniques for rectal cancer dose intensification., Patients and Methods: An online survey was made on 25 items (characteristics, simulation, imaging, volumes, doses, planning and treatment)., Results: Thirty-eight radiation oncologists joined the study. Twenty-one delivered long-course radiotherapy with dose intensification. Boost volume was delineated on diagnostic magnetic resonance imaging (MRI) in 18 centres (85.7%), and computed tomography (CT) and/or positron emission tomography-CT in 9 (42.8%); 16 centres (76.2%) performed co-registration with CT-simulation. Boost dose was delivered on gross tumor volume in 10 centres (47.6%) and on clinical target volume in 11 (52.4%). The most common total dose was 54-55 Gy (71.4%), with moderate hypofractionation (85.7%). Intensity-modulated radiotherapy (IMRT) was used in all centres, with simultaneous integrated boost in 17 (80.8%) and image-guidance in 18 (85.7%)., Conclusion: A high quality of treatment using dose escalation can be inferred by widespread multidisciplinary discussion, MRI-based treatment volume delineation, and radiation delivery relying on IMRT with accurate image-guided radiation therapy protocols., (Copyright © 2021 International Institute of Anticancer Research (Dr. George J.

Purpose: The effect of neoadjuvant chemoradiotherapy (CRT) and the relationship between pathological complete response (pCR) with clinical outcomes has been evaluated in elderly locally advanced rectal cancer (LARC) patients., Methods: We retrospectively analyzed 117 LARC patients treated with conformal RT and concomitant fluoropirimidine-based chemotherapy. A dose of 4500 cGy, on the pelvis, up to 5500 cGy on the tumor was delivered. Multidisciplinary evaluation, including geriatric assessment, was previously performed to identify frail patients unsuitable for combined treatment., Results: The median age was 75 (range 70-88 years), and 103 (88%) patients had ECOG Performance Status (PS) = 0. All patients except one completed CRT. Ten (8.5%) patients temporarily suspended CRT for acute severe hematologic complication, diarrhea and/or proctitis and hypokalemia. Of the 103 operated patients (88%), a pCR, according to Mandard tumor regression grade (TRG) score, was obtained in 28 patients (27.2%), with TRG1-2 rate of 43.7%. The 3- and 5-year overall survival (OS) rates were 80.2% ± 4.2% and 68.0% ± 5.2%, 72.4% ± 4.5% and 57.8% ± 5.2% for disease-free survival (DFS), and 92.2% ± 2.8% and 89.5% ± 3.9% for loco-regional control. Patients with TRG1-2 had 3- and 5-year OS rates of 84.1% ± 6.6% and 84.1% ± 6.6% compared with 82.8% ± 5.5% and 67.7% ± 7.2% for patients with TRG3-5 (p = 0.012). The 3- and 5-year DFS rates for patients with TRG1-2 were 77.6% ± 7.0% and 74.2% ± 7.5% compared with 70.9% ± 6.3% and 54.7% ± 7.3% for patients with TRG3-5 (p = 0.009)., Conclusion: Our results reported good tolerability and clinical outcomes of neoadjuvant CRT, with a benefit in patients ≥ 70 years, confirming the prognostic role of pCR on clinical outcomes.

Diagnosis of thoracic lesions on the basis of history and physical examination is often challenging. Diagnostic imaging is therefore of paramount importance in this field. Radiology has traditionally been considered the diagnostic procedure of choice for these diseases. Nevertheless, it is often not possible to differentiate inflammatory/infectious lesions from neoplastic diseases. A correct cytological and histopathologic diagnosis is therefore needed for an accurate diagnosis and subsequent prognostic and therapeutic approach. In human medicine, Computed Tomography (CT) and CT-guided biopsy are used in the presence of lesions which are not adequately diagnosed with other procedures. In the present study, thoracic lesions from 52 dogs and 10 cats of different sex, breed and size underwent both CT-guided fine-needle aspiration (FNAB) and tissue-core biopsy (TCB). Clinical examination, hematobiochemical analysis and chest radiography were performed on all animals. In this study, 59 of 62 histopathological samples were diagnostic (95.2%). Cytology was diagnostic in 43 of 62 samples (69.4%). General sensitivity, accuracy and PPV for FNAB and TCB were 67.7%, 67.7% and 100% and 96.7%, 95.2% and 98.3%, respectively. Combining the two techniques, the overall mean accuracy for diagnosis was 98.4%. Nineteen of 62 cases showed complications (30.6%). Mild pneumothorax was seen in 16 cases, whereas mild hemorrhage occurred in three cases. No major complications were encountered. CT-guided FNAB cytology can be considered a useful and reliable technique, especially for small lesions or lesions located close to vital organs and therefore dangerous to biopsy in other way.

Insulin resistance (IR), currently called prediabetes (PD), affects more than half of the adult population worldwide. Type 2 diabetes (T2D), which often follows in the absence of treatment, affects more than 475 million people and represents 10-20% of the health budget in industrialized countries. A preventive public health policy is urgently needed in order to stop this constantly progressing epidemic. Indeed, early management of prediabetes does not only strongly reduce its evolution toward T2D but also strongly reduces the appearance of cardiovascular comorbidity as well as that of associated cancers. There is however currently no simple and reliable test available for the diagnosis or screening of prediabetes and it is generally estimated that 20-60% of diabetics are not diagnosed. We therefore developed an ELISA for the quantitative determination of serum Insulin-Regulated AminoPeptidase (IRAP). IRAP is associated with and translocated in a stoechiometric fashion to the plasma membrane together with GLUT4 in response to insulin in skeletal muscle and adipose tissue which are the two major glucose storage sites. Its extracellular domain (IRAPs) is subsequently cleaved and secreted in the blood stream. In T2D, IRAP translocation in response to insulin is strongly decreased. Our patented sandwich ELISA is highly sensitive (≥10.000-fold "normal" fasting concentrations) and specific, robust and very cost-effective. Dispersion of fasting plasma concentration values in a healthy population is very low (101.4 ± 15.9 μg/ml) as compared to those of insulin (21-181 pmol/l) and C-peptide (0.4-1.7 nmol/l). Results of pilot studies indicate a clear correlation between IRAPs levels and insulin sensitivity. We therefore think that plasma IRAPs may be a direct marker of insulin sensitivity and that the quantitative determination of its plasma levels should allow large-scale screening of populations at risk for PD and T2D, thereby allow the enforcement of a preventive health policy aiming at efficiently reducing this epidemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Trocmé, Gonnet, Di Tommaso, Samouda, Cracowski, Cracowski, Lambert-Porcheron, Laville, Nobécourt, Gaddhab, Le Lay, Bohn, Poitou, Clément, Al-Mulla, Bitar and Bottari.)

Objectives: The study aimed to evaluate the efficacy of a eutectic lidocaine/prilocaine cream (EMLA cream; Astra Pharmaceuticals) in reducing pain and reaction to venepuncture during jugular blood sampling in cats after a 30-min topical application time., Methods: The study was a prospective, blind, controlled clinical trial. Eighteen healthy client-owned cats were randomly allocated to two study groups. All cats were clipped on the left jugular groove region and then, depending on the study group, either the placebo (liquid paraffin) or EMLA cream was applied to the region. The area was then kept protected for the next 30 mins. Except for the operator who administered the product, all operators were blinded to the study groups. Blood sampling was performed by an experienced operator and a stress score was assigned to each cat according to the reactions observed during the venepuncture. Also, the procedure was classified as being 'easy' or 'difficult' by the same operator., Results: A significantly reduced stress score was observed in cats that received the EMLA cream compared with those belonging to the placebo group ( P  = 0.048); withdrawal movements were observed in 1/9 cats treated with the EMLA cream vs 7/9 cats of the placebo group ( P  = 0.015). The jugular venepuncture was defined as easy in 1/9 cats that received the placebo and in 8/9 cats in the EMLA group ( P  = 0.015)., Conclusions and Relevance: The present study provides evidence for the efficacy of the EMLA cream after a 30-min application time for jugular venepuncture in cats, together with significantly reduced stress for patients. Therefore, this study supports the routine use of EMLA cream as good practice to enhance the welfare of cats and to simplify venepuncture procedures.

Canine atopic dermatitis (CAD) is a pruritic allergic skin disease associated with IgE-mediated hypersensitivity. IgE is detected using Serum Allergen-Specific IgE test (SAT) in order to identify allergens. The present study aims to identify the environmental allergens in atopic dogs living in Northern Italy using SAT. The screening SAT (sSAT), using a monoclonal antibody cocktail-based ELISA to identify indoor and outdoor allergens, was performed. In all positive samples, an anti-IgE monoclonal antibody ELISA test was performed to extend panel of allergens. Out of 117 selected dogs, 69 were included in the study; 71% were positive and 29% were negative to sSAT. Among the 49 positive sSAT, 53% were positive for both indoor and outdoor, 38.8% only for indoor, and 8.2% only for outdoor allergens. This is the first study on the frequency of allergens involved in CAD in Italy using SAT. IgE hypersensitivity in atopic dogs of Northern Italy is usually associated with indoor allergens, primarily house dust mites. Among the outdoor allergens, an important role was played by Rumex acetosa . Polysensitization also commonly occurs. Therefore, since the numerous factors affect the IgE positivity in CAD, specific panels for geographical areas should be considered and re-evaluated at time intervals.

Objective: To assess whether repeat cervical-length (CL) measurement in women discharged from hospital after their first episode of threatened preterm labor can predict their risk of spontaneous preterm birth., Methods: This was a secondary analysis of a randomized controlled trial of maintenance tocolysis, in which CL was measured on transvaginal ultrasound at the time of hospital discharge and after 2, 4, 8 and 12 weeks, in women who remained undelivered after their first episode of threatened preterm labor. After univariate analysis, multivariate logistic regression analysis was used to assess whether CL < 10 mm at the time of hospital discharge or at any follow-up evaluation could predict spontaneous delivery prior to 37 weeks of gestation., Results: Of 226 women discharged after a diagnosis of threatened preterm labor, 57 (25.2%) delivered spontaneously prior to 37 weeks' gestation. The risk of spontaneous preterm birth was higher among women with CL < 10 mm at hospital discharge compared to those with CL ≥ 10 mm (adjusted odds ratio (aOR), 3.3; 95% CI, 1.2-9.2). Moreover, spontaneous preterm delivery was more common when CL < 10 mm was detected up to 2 weeks (aOR, 2.9; 95% CI, 1.1-7.3) or up to 4 weeks (aOR, 7.3; 95% CI, 2.3-22.8) post discharge, as compared with when CL was persistently ≥ 10 mm. The association was not significant when considering CL measurements at 8 weeks, and there was insufficient information to assess the effect of measurements obtained at 12 weeks., Conclusions: Women who remain undelivered after their first episode of threatened preterm labor continue to be at high risk of spontaneous preterm birth if their CL is below 10 mm at the time of hospital discharge or at any follow-up visit up to 4 weeks later. CL measurement could be included in the antenatal care of these women in order to stratify their risk of preterm birth, rationalize resource utilization and help clinicians improve pregnancy outcome. © 2020 International Society of Ultrasound in Obstetrics and Gynecology., (© 2020 International Society of Ultrasound in Obstetrics and Gynecology.)

Due to migration and international travels, obstetricians are increasingly faced with a globalized obstetric setting and should adapt their daily clinical and diagnostic approach to the modifications of tropical and subtropical infections epidemiology. This paper is focused on five emerging infectious diseases, namely Chagas disease, HTLV-1 infection, malaria, schistosomiasis and Zika virus infection, having a high prevalence in migrant populations and which can affect international travelers. These diseases frequently pass unrecognized since they are characterized by few or no symptoms during pregnancy, however they may cause a relevant maternal, fetal and neonatal impact. Specific and reliable diagnostic and treatment options are available but are rarely used during routine obstetrical practice., Competing Interests: Declaration of Competing Interest The authors report no declarations of interest., (Copyright © 2020 Elsevier B.V.

We report the results of a targeted testing strategy for five emerging infectious diseases (Chagas disease, human T-lymphotropic virus 1 infection, malaria, schistosomiasis, and Zika virus infection) in pregnant women accessing an Italian referral centre for infectious diseases in pregnancy for unrelated reasons. The strategy is based on a quick five-question questionnaire which allows the identification of pregnant women at risk who should be tested for a specific disease. One hundred and three (24%) out of 429 pregnant women evaluated in a 20 month period were at risk for at least one emerging infectious disease. Three (2.9%, all from sub-Saharan Africa) out of 103 at-risk women resulted in being affected (one case of Plasmodium falciparum malaria, two cases of schistosomiasis) and were appropriately managed. Prevalence of emerging infectious disease was particularly high in pregnant women from Africa (three out of 25 pregnant women tested, 12%). The proposed strategy could be used by health care professionals managing pregnant women in non-endemic setting, to identify those at risk for one of the five infection which could benefit for a targeted test and treatment.

In accordance with women's preferences guidelines, referring to population-based and randomized trials, which recommends counseling women with vertex-first twins to attempt a vaginal delivery. Yet, the rising rates of twin caesareans are associated with the decline in skills of senior and junior obstetricians. Although noncephalic second twins have been in the focus of interest, prompt delivery of cephalic second twins can be trickier when the head does not engage. We illustrate how to avoid complications during instrumental delivery or internal podalic version and breech extraction of the second twin encouraging to start when membranes are still intact.

A 14-y-old spayed female Labrador Retriever was presented with an 8-mo history of chronic vomiting. Abdominal ultrasound and gastrointestinal endoscopy revealed a mass protruding into the gastric lumen, with cytologic features suggestive of sarcoma. A partial gastrectomy was performed; the gastric body and antrum were thickened, with a cerebriform appearance of the mucosal surface. Histologic examination revealed a submucosal neoplastic proliferation of fusiform cells variably arranged in irregular bundles and scattered whorls. Fusiform cells strongly reacted to antibodies against vimentin, S100, and neuron-specific enolase; glial fibrillary acidic protein was moderately and multifocally expressed. Pancytokeratin, KIT, α-smooth muscle actin, and desmin were nonreactive. Histologic and immunohistochemical findings suggested a diagnosis of gastric sarcoma with features referable to a non-GIST (gastrointestinal stromal tumor), non-smooth muscle NIMT (non-angiogenic, non-lymphogenic intestinal mesenchymal tumor). The overlying gastric mucosa was thickened by elongated and dilated gastric glands, predominantly lined by intensely periodic acid-Schiff-stained mucous cells. This altered mucosal architecture was suggestive of Ménétrier-like disease. Although this disease has been hypothesized to predispose to gastric adenocarcinoma in dogs, an association with gastric sarcoma has not been documented previously in the veterinary literature, to our knowledge.

Purpose: Due to a reported dose-response relationship in rectal cancer radiotherapy, a greater interest in dose intensification on small boost volume arises. Considering the need of an appropriate target movements evaluation, this retrospective study aimed to use cone-beam computed tomography (CBCT) for GTV and mesorectum organ motion (OM) evaluation, in locally advanced rectal cancer (LARC) patients treated with neoadjuvant chemo-radiotherapy, in prone and supine position., Methods: Thirty-two LARC patients were analyzed. GTV and mesorectum were delineated on MRI co-registrated with CT simulation. GTV and mesorectum OM was estimated on all CBCTs, performed during treatment, co-registrated with CT simulation. OM evaluation was obtained, as mean shift in left and right (L-R), postero-anterior (P-A) and cranio-caudal (Cr-C) directions. Volumes variability was calculated by DICE index., Results: A total of 296 CBCTs were analyzed. Mean shifts of the GTV and mesorectum in prone position were - 0.16 cm and 0.15 cm in L-R direction, 0.28 cm and - 0.40 cm in P-A direction, and 0.14 cm and - 0.21 cm, in Cr-C direction; for supine position the mean shifts of the GTV were - 0.10 cm and 0.17 cm in R-L direction, 0.26 cm and - 0.23 cm in A-P direction, 0.09 cm and - 0.11 cm in Cr-C direction. Mean DICE index for GTV and mesorectum was 0.74 and 0.86, in prone position, and 0.78 and 0.89 in supine position, respectively., Conclusion: GTV and mesorectum OM was less than 4 mm in all directions in both positions, with a 1 mm less deviation in supine position. CBCTs resulted effective for OM assessment, and it could be an appropriate method for the implementation on an intensification treatment.

The liver has a unique vascular supply, and triple-phase contrast-enhanced computed tomography examinations are being performed in order to characterize liver lesions. This study aimed to look for any associations between the attenuation values of liver lesions and their histological classification. The inclusion criteria for this retrospective study were focal or multifocal liver lesions and histological diagnosis. All of the dogs underwent pre-contrast and triple-phase postcontrast computed tomography (CT) examinations with identical timings of the postcontrast series. Thirty-one dogs were included in the study, and various benign and malignant pathologies were identified. The results did not identify any significant differences between the benign and malignant liver lesions, nor between the individual histological diagnoses. Inflammatory lesions were significantly different compared to the normal liver parenchyma, and significant hypoattenuation was found in the portal and delayed venous phases. Hemangiosarcomas were significantly hypoattenuating to the normal liver parenchyma in the pre-contrast and arterial phases, and also to all of the benign lesions in the arterial phase. The other pathologies showed variable attenuation patterns in the different postcontrast phases, and differentiation was not possible. On the basis of this study, triple-phase contrast-enhanced computed tomography cannot differentiate between benign and malignant liver lesions, and biopsy and further histological analysis are necessary.

The vaginal microbiota plays a critical role in pregnancy. Bacteria from Lactobacillus spp. are thought to maintain immune homeostasis and modulate the inflammatory responses against pathogens implicated in cervical shortening, one of the risk factors for spontaneous preterm birth. We studied vaginal microbiota in 46 pregnant women of predominantly Caucasian ethnicity diagnosed with short cervix (<25 mm), and identified microbial communities associated with extreme cervical shortening (≤10 mm). Vaginal microbiota was defined by 16S rRNA gene sequencing and clustered into community state types (CSTs), based on dominance or depletion of Lactobacillus spp. No correlation between CSTs distribution and maternal age or gestational age was revealed. CST-IV, dominated by aerobic and anaerobic bacteria different than Lactobacilli , was associated with extreme cervical shortening (odds ratio (OR) = 15.0, 95% confidence interval (CI) = 1.56-14.21; p = 0.019). CST-III ( L. iners -dominated) was also associated with extreme cervical shortening (OR = 6.4, 95% CI = 1.32-31.03; p = 0.02). Gestational diabetes mellitus (GDM) was diagnosed in 10/46 women. Bacterial richness was significantly higher in women experiencing this metabolic disorder, but no association with cervical shortening was revealed by statistical analysis. Our study confirms that Lactobacillus -depleted microbiota is significantly associated with an extremely short cervix in women of predominantly Caucasian ethnicity, and also suggests an association between L. iners -dominated microbiota (CST III) and cervical shortening.

Background/aim: This study aimed to investigate the bolus practice among Italian radiation oncologists., Patients and Methods: In 2018, a survey on bolus application was sent to all members of the Italian Association of Radiotherapy and Clinical Oncology., Results: The survey was joined by 102 radiation oncologists. Not all respondents answered to every question. A 69.5% of 82 respondents used bolus in case of skin infiltration and 52 of 68 respondents (76.5%) applied it every day. Skin was included as part of chest wall Clinical Target Volume both in the absence or the presence of breast reconstruction. Five mm bolus was the most used. 3D Conformal radiotherapy was the most used technique, in 73.5% of cases. Acute RTOG G2-G3 skin toxicity was recorded by 93.9% physicians., Conclusion: There was heterogeneity in the use of bolus, though an agreement was found in some topics. The achievement of a National Consensus may represent an interesting future goal., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Background: COVID-19 in Italy has led to the need to reorganize hospital protocols with a significant risk of interruption to cancer treatment programs. In this report, we will focus on a management model covering the two phases of the COVID-19 emergency, namely lockdown-phase I and post-lockdown-phase II., Methods: The following steps were taken in the two phases: workload during visits and radiotherapy planning, use of dedicated routes, measures for triage areas, management of suspected and positive COVID-19 cases, personal protective equipment, hospital environments and intra-institutional meetings and tumor board management. Due to the guidelines set out by the Ministry of Health, oncological follow-up visits were interrupted during the lockdown-phase I; consequently, we set about contacting patients by telephone, with laboratory and instrumental exams being viewed via telematics. During the post-lockdown-phase II, the oncological follow-up clinic reopened, with two shifts operating daily., Results: By comparing our radiotherapy activity from March 9 to May 4 2019 with the same period in 2020 during full phase I of the COVID-19 emergency, similar results were achieved. First radiotherapy visits, Simulation Computed Tomography and Linear Accelerator treatments amounted to 123, 137 and 151 in 2019 compared with 121, 135 and 170 in 2020 respectively. There were no cases of COVID-19 positivity recorded either in patients or in healthcare professionals, who were all negative to the swab tests performed., Conclusion: During both phases of the COVID-19 emergency, the planned model used in our own experience guaranteed both continuity in radiotherapy treatments whilst neither reducing workload nor interrupting treatment and, as such, it ensured the safety of cancer patients, hospital environments and staff.

Background: Aelurostrongylus abstrusus is the most important nematode affecting the respiratory tract of cats in terms of prevalence and clinical relevance. The aim of this randomised controlled field study was to confirm the efficacy of the spot-on containing emodepside/praziquantel (Profender, Bayer Animal Health) in the treatment of aelurostrongylosis., Methods: Seventeen cats with aelurostrongylosis and presenting with clinical and/or radiographic signs were included in the study. Eight cats received two biweekly doses of emodepside/praziquantel, while nine cats were allocated to a control group and received a rescue treatment at the end of the study. Clinical response was the primary outcome, while the secondary end point was the reduction of larval shedding in faeces., Results: Two weeks after the first application, the cats showed a significant, though partial, recovery of clinical signs with complete clinical and parasitological resolution. The resolution of inflammatory leucogram and a significant reduction of radiographic lesions were observed two weeks after the second treatment. Red blood cells and albumin values significantly increased after eight weeks from the second application, together with the complete regression of radiographic patterns., Conclusion: Two applications of this spot-on solution two weeks apart assured complete cessation of larval shedding and led to a complete clinical, clinicopathological and radiographic recovery., Competing Interests: Competing interests: RS and FP are currently employed by Bayer Animal Health., (© British Veterinary Association 2019.

Background: Congenital cytomegalovirus (CMV) infection is the leading infectious cause of neurological impairment for which, currently, there are no approved antenatal treatment options., Objectives: The aim of this article was to summarize the available evidence on the use of valacyclovir during pregnancy to prevent and treat congenital CMV infection and disease., Sources: Two databases (PubMed and ClinicalTrial.gov) were reviewed., Content: Six relevant documents were identified, namely one observational study, three clinical trials, two case reports. Most relevant findings were those from two clinical trials. A phase 2/3 placebo-controlled study showed a decrease of 71% (5 of 45 vs 14 of 47) in rate of CMV vertical transmission in women treated with 8 g/day valacyclovir following primary CMV infection in pregnancy. A phase 2, single-arm clinical trial, showed that 8 g/day valacyclovir administered to mothers of symptomatic infected foetuses increased the portion of asymptomatic neonates to 82% (34 of 41), compared with 43% (20 of 47) in untreated pregnancies from a historical cohort., Implications: Studies in favour of using valacyclovir during pregnancy for prevention and treatment of congenital CMV infection are emerging but are still few. Randomized clinical trials on large cohorts of patients investigating the efficacy on prevention and treatment of congenital CMV are required. Unfortunately, this will be probably not be feasible at least in the short period. In the meantime, data on the 'off label' use of valacyclovir for CMV in pregnancy could be collected within a multicentre observational study., (Copyright © 2020 European Society of Clinical Microbiology and Infectious Diseases.

Molecular-based approaches are rapidly developing in medicine for the evaluation of physiological and pathological conditions and discovery of new biomarkers in prevention and therapy. Fatty acid diversity and roles in health and disease in humans are topical subjects of lipidomics. In particular, membrane fatty acid-based lipidomics provides molecular data of relevance in the study of human chronic diseases, connecting metabolic, and nutritional aspects to health conditions. In veterinary medicine, membrane lipidomics, and fatty acid profiles have not been developed yet in nutritional approaches to health and in disease conditions. Using a protocol widely tested in human profiling, in the present study erythrocyte membrane lipidome was examined in 68 clinically healthy dogs, with different ages, sex, and sizes. In particular, a cluster composed of 10 fatty acids, present in membrane glycerophospholipids and representative of structural and functional properties of cell membrane, was chosen, and quantitatively analyzed. The interval values and distribution for each fatty acid of the cluster were determined, providing the first panel describing the healthy dog lipidomic membrane profile, with interesting correlation to bodyweight increases. This molecular information can be advantageously developed as benchmark in veterinary medicine for the evaluation of metabolic and nutritional status in healthy and diseased dogs., (Copyright © 2020 Prasinou, Crisi, Chatgilialoglu, Di Tommaso, Sansone, Gramenzi, Belà, De Santis, Boari and Ferreri.)

Objective: To evaluate whether intrapartum cardiotocography with computer analysis decreases the incidence of newborn metabolic acidosis or obstetric intervention when compared with visual analysis through a systematic review with meta-analysis of randomized controlled trials. Methods: The research was conducted using Medline, Embase, Web of Science, Scopus, ClinicalTrial.gov, Ovid and Cochrane Library as electronic databases from the inception of each database to May 2018. Selection criteria included randomized trial evaluating women with cephalic presentation at term or late preterm term during labor who were randomized to electronic fetal heart rate monitoring with either computer analysis (i.e. intervention group) or standard visual analysis (i.e. control group). Trials evaluating antenatal fetal heart rate monitoring in women not in labor were excluded. The primary outcome was incidence of newborn metabolic acidosis, defined as pH less than 7.05 and base deficit greater than 12 mmol/L. Secondary outcomes were mode of delivery, admission to neonatal intensive care unit, hypoxic-ischemic encephalopathy, and perinatal death. The summary measures were reported as relative risk (RR) with 95% confidence interval (CI). Results: Three randomized controlled trials (RCTs), including 54,492 participants, which met inclusion criteria for this meta-analysis, were analyzed. All the included trials enrolled women with cephalic presentation at term or late preterm. Women were randomized in the active first stage of labor and all of them received continuous cardiotocography (CTG) from randomization until delivery. Women who received continuous CTG during labor with computerized analysis had similar risk of newborn metabolic acidosis. No between group differences were found in the secondary outcomes. Conclusions: Compared with visual analysis, use of computer analysis of fetal monitoring signals during labor did not significantly reduce the rate of metabolic acidosis or obstetric intervention.

Aim: To delineate cervical cancer gross tumor volume (GTV) on T2-magnetic resonance imaging (MRI) and apparent diffusion coefficient (ADC) maps, assessing volumes and inter-observer agreement between two observers., Patients and Methods: A radiologist and a radiation oncologist delineated GTV on T2 (T2 GTV ) and ADC (ADC GTV ) sequences. Dice similarity index (DICE) and Bland-Altman analysis were used to estimated concordance., Results: Mean T2 GTV and ADC GTV volumes were 43.84±71.47 cc and 37.28±68.92 cc according to the radiologist, and 43.4±70.44 cc and 36.65±69.21 cc according to the radiation oncologist. ADC led to statistically significantly smaller volumes compared to T2. The mean DICE index was 0.86 for T2 GTV and 0.84 for ADC GTV The Bland-Altman plots globally showed concordance., Conclusion: GTV delineation was smaller in the ADC maps compared to T2-MRI, reaching an almost perfect agreement between observers. Thanks to this acceptable variability, adding functional imaging might provide more information for tumor delineation, improving reproducibility for image-guided adaptive radiotherapy., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.
