43±3.75nM and 3383±81.73 CPM, respectively. In cell uptake and blocking experiments, a significant reduction in radioactivity accumulation (over 4-fold) was observed by blocking U87 and PC-3 cells with unlabeled peptide. PET imaging of U87 and PC-3 tumor-bearing mice revealed clear tumor imaging (tumor radioactivity accumulation was 3.48±0.44 and 3.68±0.76%ID/g respectively, tumor-to-muscle ratio was 3.45±0.43 and 3.64±0.76 respectively). Blocking imaging revealed that the U87 tumor uptake was significantly inhibited (2.21±0.41%ID/g). The biodistribution and dynamic PET imaging showed that [
F]FP-Lys-GE11 was mainly excreted by the kidneys and the rest was excreted through the bile and intestines.

The current results showed that [
F]FP-Lys-GE11was a good radiolabeled peptide probe for EGFR overexpression tumor's imaging.

Radiolabeled peptides play a central role in nuclear medicine as radiotheranostics for targeted imaging and therapy of cancer. We have recently proposed the use of metabolically stabilized GRPR antagonist BBN2 for radiolabeling with
F and
Ga and subsequent PET imaging of GRPRs in prostate cancer. The present work studied the impact of
Sc- and
Ga-labeled DOTA complexes attached to GRPR antagonist BBN2 on the in vitro GRPR binding affinity, and their biodistribution and tumor uptake profiles in MCF7 breast and PC3 prostate cancer models.

DOTA-Ava-BBN2 was radiolabeled with radiometals
Ga and
Sc. Gastrin-releasing peptide receptor (GRPR) affinities of peptides were assessed in PC3 prostate cancer cells. GRPR expression profiles were studied in human breast cancer tissue samples and MCF7 breast cancer cells. PET imaging of
Ga- and
Sc-labeled peptides was performed in MCF7 and PC3 xenografts as breast and prostate cancer models.

Radiopeptides [
Ga]Ga-DOTA-Ava-BBN2 and [
Sc]Sc-DOTA-Ava BBN2 ]Ga-DOTA-Ava-BBN2 and [
Sc]Sc-DOTA-Ava-BBN2 displayed comparable tumor uptake and retention profiles with rapid blood and renal clearance profiles in both tumor models.

The favorable PET imaging performance of [
Sc]Sc-DOTA-Ava-BBN2 in prostate cancer should warrant the development of an [
Sc]Sc-DOTA-Ava-BBN2 analog for clinical translation which comes with a main γ-line of much lower energy and intensity compared to
Sc.

To identify the epidemiologic and clinical risk factors associated with failed response to medical treatment in tuboovarian abscess (TOA) patients and whether there is a relationship between the presence of intrauterine device (IUD), duration of use and medical treatment success or not.

For this study, the medical records of patients diagnosed with TOA and hospitalized in an 8-year period were analyzed retrospectively. The presence of TOA and IUD was confirmed ultrasonographically in all patients. Parenteral antibiotic treatment was initiated as the first step. Patients who did not improve with this medical treatment underwent surgery. Patients who recovered with medical treatment were defined as the successful group, while those who underwent surgery after medical treatment failure were recorded as the failed group.

There were 37 patients in successful group and 87 patients in failed group. selleck inhibitor The mean age, parity, white blood count, TOA size, duration of IUD use, rate of multigravida and multiparity were higher in the failed group. Logistic regression analysis revealed that presence of multiparity, TOA size and the duration of IUD use were significant independent factors in predicting medical treatment success of TOA. The best cut-off value for TOA size was 4.5 cm and for duration of IUD use was 5.5 years in the Receiver Operating Characteristic curve analysis.

The presence of long-term IUD use, increased TOA size, and multiparity were found to be risk factors related to the failure of medical treatment in TOA cases.

We aim to evaluate the knowledge and physicians' practices concerning fertility preservation in women with endometriosis.

Descriptive, observational, national study using an online self-questionnaire, sent by email to French gynaecologists in October 2019 within 2 months.

We obtained 110 analyzable responses from mainly surgeons (54 %) and reproductive clinicians (19 %) with a good experience (average 15 years of practice). Amongst these practitioners, 91 % seemed aware of latest French recommendations on endometriosis issued in December 2017. The most commonly used surgical techniques for management of endometriomas were intra-peritoneal cystectomy (51 %), vaporization by plasma energy (29 %) and destruction by bipolar coagulation (8.5 %). Preoperative AMH was systematically or often prescribed by 78 % of the practitioners against 37.3 % who did it postoperatively. Furthermore, 74 % also considered and performed fertility preservation strategy to manage endometriosis. It was offered in situations of bio women. Operating techniques are adapted although information and education concerning fertility preservation indications seem necessary. The place of multidisciplinary concertation meeting in endometriosis appears essential both for discussion of surgical indications and for fertility preservation possibilities. Creation of dedicated structures should be encouraged.
Objective measurement is essential to represent habitual physical activity. To date only one study has objectively measured physical activity for>12months after stroke.

This study aimed to measure physical activity, cardiovascular risk factors, mobility, mood, fatigue and cognition during the 2years after rehabilitation discharge and to investigate whether stroke survivors meet physical activity and cardiovascular risk recommendations.

This was a longitudinal observational study. Survivors of a first-ever stroke admitted to a large metropolitan rehabilitation hospital were recruited. Outcomes were measured at rehabilitation discharge and 6, 12 and 24months later. Outcomes were physical activity measured by the SenseWear Armband (e.g., moderate-vigorous physical activity, steps/day) and cardiovascular risk factors (e.g., blood pressure, fasting lipid profile and plasma glucose, waist circumference, body mass index), mobility, mood, fatigue and cognition. Changes over time were evaluated with random-effects regression modelling.
