Abstract
BACKGROUND/OBJECTIVE There is a paucity of data on the management of gastrointestinal (GI) bleeding in patients with Coronavirus disease -2019 (COVID-19) amid concerns about the risk of transmission during endoscopic procedures. We aimed to study the outcomes of conservative treatment for GI bleeding in patients with COVID-19. METHODS In this retrospective analysis, 24 of 1342 (1.8%) patients with COVID-19, presenting with GI bleeding from 22nd April to 22nd July 2020, were included. RESULTS The mean age of patients was 45.8 ± 12.7 years; 17 (70.8%) were males; upper GI (UGI) bleeding: lower GI (LGI) 23:1. Twenty-two (91.6%) patients had evidence of cirrhosis- 21 presented with UGI bleeding while one had bleeding from hemorrhoids. Two patients without cirrhosis were presumed to have non-variceal bleeding. The medical therapy for UGI bleeding included vasoconstrictors-somatostatin in 17 (73.9%) and terlipressin in 4 (17.4%) patients. All patients with UGI bleeding received proton pump inhibitors and antibiotics. Packed red blood cells (PRBCs), fresh frozen plasma (FFPs) and platelets were transfused in 14 (60.9%), 3 (13.0%) and 3 (13.0%), respectively. The median PRBCs transfused was 1 (0-3) unit(s). The initial control of UGI bleeding was achieved in all 23 patients and none required an emergency endoscopy. At 5-day follow-up, none rebled or died. Two patients later rebled, one had intermittent bleed due to gastric antral vascular ectasia, while another had rebleed 19 days after discharge. Three (12.5%) cirrhosis patients succumbed to acute hypoxemic respiratory failure during hospital stay. CONCLUSION Conservative management strategies including pharmacotherapy, restrictive transfusion strategy, and close hemodynamic monitoring can successfully manage GI bleeding in COVID-19 patients and reduce need for urgent endoscopy. The decision for proceeding with endoscopy should be taken by a multidisciplinary team after consideration of the patient's condition, response to treatment, resources and the risks involved, on a case to case basis.

Abstract
Abstract
Background
France is one of the leading countries in terms of daily alcohol consumption per inhabitant. Alcohol is a major concern for emergency department (ED) since it accounts for a large part of their resources and increases behavior problems resulting in violence against staff. Individual information of French ED attendances registered in OSCOUR network are daily collected by Santé publique France, the French Public Health Agency. This study aims at describing alcohol-related ED attendances (ARA) in 2017 in France.
Methods
The OSCOUR network included 677 ED in 2017 recording 92% of national attendances. ARA were identified through the main and associated medical diagnoses coded by physicians using ICD10. The study considered acute alcohol intoxication, dependence syndrome/withdrawal state, other mental disorders and intoxications due to alcohol, chronic complications and intentional self-poisoning by alcohol. The number of ARA was analyzed by age group, gender and region.
Results
1.4% of total attendances were associated to alcohol consumption (202,184 attendances) in 2017. 68% of ARA were due to acute alcohol intoxication and 14% for dependence syndrome/withdrawal state. The highest proportions of ARA were observed for people aged 40-59 yo and 18-24 yo, particularly for women. Regions of North and West metropolitan France and La Réunion Island had the highest proportion of ARA among the total number of attendances.
Conclusions
The part of ARA in France is consistent with figures provided in international studies using similar data. This proportion is similar with proportion of major public health issues like influenza, that represented 1% of the total ED attendances from November 2016 to February 2017 and reached 1.8% in January (month of the epidemic peak). Consequences of alcohol use represent a heavy burden for ED and the health system in France. This is all the more true as ARA are underestimated due to the low coding rate of associated medical diagnosis in ED.
Key messages
1.4% of total French ED attendances were associated to alcohol consumption in 2017. This proportion is close to the proportion of influenza attendances in ED.

Abstract
BACKGROUND Transversus abdominis plane (TAP) block is widely used as a part of pain management after various abdominal surgeries. We evaluated the effect of TAP block as an add-on to the routine analgesic regimen in patients undergoing robot-assisted laparoscopic hysterectomy. METHODS In a prospective blinded study, 70 patients scheduled for elective robot-assisted laparoscopic hysterectomy were randomised to receive either TAP block (ropivacaine 0.5%, 20 ml on each side) or sham block (isotonic saline 0.9%, 20 ml on each side). All patients had patient-controlled analgesia (PCA) with morphine on top of paracetamol and ibuprofen or diclofenac. For the first 24 post-operative hours, we monitored PCA morphine consumption and pain scores with visual analogue scale (VAS) at rest and while coughing. Post-operative nausea and number of vomits (PONV) were recorded. RESULTS Sixty-five patients completed the study, 34 receiving TAP block with ropivacaine and 31 receiving sham block with isotonic saline. We found no differences in median (interquartile range) morphine consumption the first 24 h between the TAP block group [17.5 mg (6.9-36.0 mg)] and the placebo group [17.5 mg (2.9-38.0 mg)] (95% confidence interval 10.0-22.6 mg, P = 0.648). No differences were found for VAS scores between the two groups, calculated as area under the curve/1-24 h, neither at rest (P = 0.112) nor while coughing (P = 0.345), or for PONV between groups. CONCLUSIONS In our study, the TAP block combined with paracetamol and Nonsteroidal anti-inflammatory drugs (NSAID) treatment, had no effect on morphine consumption, VAS pain scores, or frequency of nausea and vomiting after robot-assisted laparoscopic hysterectomy compared with paracetamol and NSAID alone.

Abstract
21004 Background: YKL-40 is secreted by tumor cells, macrophages and neutrophils. The exact function of YKL-40 in cancer is unknown. It may be a growth, differentiation or survival factor and play a role in angiogenesis. High serum levels of YKL-40 are associated with a poor prognosis in a variety of solid and hematological malignancies. The aim of this study was to examine if serum YKL-40 is a prognostic biomarker in patients with cervical cancer. Methods: YKL-40 was determined by ELISA (Quidel, Santa Clara, CA) in pretreatment serum samples from 116 patients with cervical cancer (FIGO stage Ia (N=5), Ib (N=55), II (N=27), III (N=25) and IV (N=4); median age 50, range 27–87 years). The median follow-up time was 3.2 years (range 2.1–4.4 years). 18 patients had a recurrence and 28 patients died. Results: Serum YKL-40 was increased (p<0.001) in the patients with cervical cancer (median 76 μg/l, range 20–2310) compared to healthy women (43 μg/l, range 20–172). Serum YKL-40 was higher than the age-corrected 95th percentile of serum YKL-40 in healthy women in 35% of the patients. Patients with high serum YKL-40 had significantly shorter survival than patients with normal serum YKL- 40 (HR=3.1, 95% CI: 1.5–6.5, p=0.002, logrank test). Univariate Cox analysis of serum YKL-40 (log transformed and treated as a continuous covariate) showed significant association with overall survival (HR=2.3, 95% CI: 1.7–3.2, p<0.0001). Multivariate Cox analysis including stage, menopausal status and serum YKL-40 (log transformed and treated as a continuous covariate) showed that stage (stage II+III vs. I: HR=6.4, 95% CI: 1.8–22.5, p=0.004) and serum YKL-40 (HR=1.6, 95% CI: 1.1–2.4, p=0.02) were independent prognostic variables of overall survival. Univariate Cox analysis of serum YKL-40 (log transformed and treated as a continuous covariate) demonstrated a significant association with risk of recurrence (HR=1.7, 95% CI: 1.1–2.7, p=0.02). Conclusion: Serum YKL-40 is a prognostic biomarker of recurrence-free and overall survival in patients with cervical cancer. No significant financial relationships to disclose.

Abstract
5047 Background: YKL-40 is secreted by cancer cells, macrophages and neutrophils. The exact function of YKL-40 is unknown. It may be a growth or differentiation factor, play a role in angiogenesis or protect against apoptosis. High serum YKL-40 is associated with poor prognosis in breast-, colorectal-, ovarian-, prostate-, small cell lung cancer and malignant melanoma. The aim was to examine serum YKL-40 in patients with cervical cancer and cervical intraepithelial neoplasia (CIN). Methods: YKL-40 was determined by ELISA (Quidel, Santa Clara, CA) in pretreatment serum samples from 116 patients with cervical cancer (FIGO stage Ia (N = 5), Ib (N = 55), II (N = 27), III (N = 25) and IV (N = 4); median age 50, range 27–87 years) and 152 patients with cervical CIN (34 years, 20–80 years). The controls included 63 healthy women undergoing sterilization (36 years, 25–59 years) and a group of 134 healthy women (51 years, 18–79 years). Results: Serum YKL-40 was increased (p < 0.001) in the patients with cervical cancer (median 76 μg/l, range 20–2310) compared to patients with CIN (45 μg/l, 20–288), women undergoing sterilization (37 μg/l, 20–125) and healthy women (43 μg/l, 20–172). Patients with CIN had slightly elevated serum YKL-40 levels. Serum YKL-40 increased with increasing stage (Ia: median 36 μg/l, range 26–137; Ib: 56 μg/l, 20–984; II: 92 μg/l, 28–2310; III: 163 μg/l, 40–1474; and IV: 224 μg/l, 137–391; p < 0.001 Kruskal-Wallis test). All stage IV patients, 72% stage III, 52% stage II, 24% stage Ib, 40% stage Ia and 13% of patients with CIN had elevated serum YKL-40 compared to healthy controls (95th percentile). Patients with squamous cell carcinoma had higher serum YKL-40 (median 92 μg/l, range 27–2310, N = 86) compared to patients with adenosquamous (67 μg/l, 20–93, N = 9, p = 0.027) and adenocarcinoma (43 μg/l, 20–1472, N = 20, p < 0.001). Conclusion: Median serum YKL-40 is elevated in patients with stage Ib - IV cervical cancer. The serum level of YKL-40 seems to be correlated to the stage. No significant financial relationships to disclose.

Abstract
OBJECTIVE To determine the progression/regression rate of cervical intraepithelial neoplasia in pregnancy and to describe the number of patients requiring treatment for cervical neoplasia during or following the pregnancy. METHODS A retrospective analysis of 305 pregnant women with abnormal cervical cytology was performed. The colposcopic, cytologic and histologic findings of repeated examinations during pregnancy and of the subsequent examination eight weeks postpartum were registered and compared. All smears were obtained by cotton bud and Cytobrush. Colposcopy was performed using standard techniques and cervical biopsies were taken in case of colposcopic abnormalities. Endocervical curettage was omitted during pregnancy. At postpartum evaluation colposcopy, directed biopsies and endocervical curettage were performed in all cases. RESULTS One hundred and two patients (33%) were followed only by cytology and colposcopy. The remaining 203 patients (67%) had one to four colposcopically directed biopsies during the pregnancy. Comparing the initial histology in pregnancy to the postpartum histologic evaluation 25% showed spontaneous regression while 75% of the women exhibited progression (28%) or persistence (47%) in the severity of cervical neoplasia. Two patients were treated by cervical conization in early pregnancy and 143 women (53%) were treated within the first year after the pregnancy. In the postpartum period microinvasive carcinoma was diagnosed in two patients, but no women advanced to more serious stages of cervical cancer. CONCLUSIONS The high persistence rate of cervical intraepithelial neoplasia in pregnancy leads us to recommend a liberal use of colposcopically directed biopsies during pregnancy and to ensure a high follow-up rate in the postpartum period.

Abstract
The aim of the study was to elucidate the localization, distribution, colocalization and biological effect of preproVIP-derived peptides in the human female genital tract. Radioimmunoassays applying antisera against the five functional domains of the VIP precursor in combination with immunohistochemistry were used. The effect of preproVIP 22-79, preproVIP 111-122 and preproVIP 156-170 on genital smooth muscle activity in the Fallopian tube was investigated in vitro and compared to that of VIP. All the preproVIP-derived peptides were expressed throughout the genital tract in neuronal elements closely related to the epithelial lining, perivascular tissue and non-vascular smooth muscle. Colocalization of the peptides was evidenced by double immunostaining. In contrast to VIP, preproVIP 22-79, preproVIP 111-122 and preproVIP 156-170 did not cause a significant inhibition of smooth muscle activity. The findings indicate that tissue-specific differences in post-translational processing of preproVIP exist in the female genital tract.

Abstract
The distribution, localization, and smooth muscle effects of pituitary adenylate cyclase-activating polypeptide (PACAP) were studied in the human female genital tract. The concentrations of PACAP-38 and PACAP-27 were measured by radioimmunoassays, and both peptides were found throughout the genital tract. The highest concentrations of PACAP-38 were detected in the ovary, the upper part of vagina, and the perineum. The concentrations of PACAP-27 were generally low, in some regions below the detection limit and in other regions 1 to 5% of the PACAP-38 concentrations. Immunocytochemistry revealed that PACAP was located in delicate varicose nerve fibers that were most abundant in the internal cervical os, where they mainly seemed to innervate blood vessels and smooth muscle cells. PACAP-38 and PACAP-27 (10(-10)-10(-6) M) caused a concentration-dependent relaxation of the spontaneous activity of the nonvascular smooth muscle strips from fallopian tube and myometrium in vitro. Likewise, both peptides (10(-10)-10(-6) M) caused relaxation of nonrepinephrine (10(-6) M)-precontracted intramyometrial arteries. No effect of the PACAP sequences, PACAP-(6-27), PACAP-(16-38), and PACAP-(18-27), on fallopian tube was observed. The findings suggest a smooth muscle regulatory role of PACAP in the human female reproductive tract.

Abstract
The occurrence of vasoactive intestinal polypeptide (VIP), peptide histidine methionine (PHM) and peptide histidine valine (PHV) in the human female genital tract was studied by means of radioimmunoassay in combination with gel chromatography. In addition, the effect of PHV on genital smooth muscle activity was investigated in vitro and compared to that of VIP. Immunoreactive VIP, PHM and PHV were present in all regions of the human female genital tract, the highest concentrations being measured in the vagina and the uterine cervix. The peptides displayed similar regional distribution and as expected from the structure of the VIP precursor molecule in which the examined peptides are contained, the molar ratio of VIP to the total PHM/PHV immunoreactivity was close to 1:1. In all regions PHV constituted 50-70% of the total PHM/PHV immunoreactivity indicating that the dibasic conversion site after PHM was uncleaved. VIP and PHV were found to be equipotent relaxants of the smooth muscle from the Fallopian tube and the myometrium. The present study indicates that PHV like PHM and VIP may act as a neurotransmitter in the human female genital tract and thus participate in the local nervous control of the reproductive functions.

Abstract
The effect of increasing doses of PHM given subepithelially or intravenously on vaginal blood flow was studied. Vaginal blood flow was measured by a heated oxygen electrode, and the concentration of PHM in peripheral plasma was monitored radioimmunochemically. Injection of PHM induced a significant dose-dependent increase in vaginal blood flow. The flow values correlated with the plasma concentrations independent of the way of administration. The efficacy was the same as previously found for VIP but the potency of subepithelially injected PHM was found to be 10-fold lower than that of VIP. In conclusion, PHM and VIP seem to have similar vasodilatory effects upon vaginal blood flow.

Abstract
1. The present study was performed to examine and compare the effect of increasing doses of vasoactive intestinal polypeptide (VIP) on vaginal blood flow following vaginal subepithelial and intravenous injection in normal women. 2. Local vaginal blood flow was measured by a heated oxygen electrode. 3. Peripheral blood samples were collected throughout the experiments for VIP analysis by radioimmunoassay. 4. Both subepithelial and intravenous injections induced a significant and dose-dependent increase in vaginal blood flow (P less than 0.05), displaying the same efficacy, potency and sensitivity. 5. The vaginal flow values correlated with the corresponding plasma VIP concentrations after both routes of administration. 6. The systemic vascular side effects; that is, flushing, hypotension and tachycardia, were observed following both subepithelial and intravenous injection. 7. The findings indicate that the effect of VIP on vaginal blood flow irrespective of route of administration is part of a systemic vasodilatory effect rather than a local response.

Abstract
The occurrence of the neuropeptides peptide histidine methionine (PHM) and vasoactive intestinal peptide (VIP) in the human female genital tract was studied by means of immunochemistry and radioimmunoassay in combination with gel chromatography. In addition, the effect of PHM and VIP on smooth muscle activity was investigated in vitro. The regional distribution of PHM as determined by radioimmunoassay correlated with that of VIP. This finding agreed with the immunohistochemical data, which, in addition, provided evidence for colocalization of the two peptides in nerve fibers. These fibers were most abundant in the vagina and the uterine cervix, where they seemed to innervate blood vessels, smooth muscle, and epithelial cells. The concentrations of immunoreactive PHM and VIP were found to be similar in all areas except in the vagina, where the PHM concentration was fourfold that of VIP. Gel chromatography of vaginal extract revealed a high concentration of a C-terminally extended form of PHM, suggesting differential processing pathways of the VIP precursor. Both PHM and VIP inhibited, in a dose-dependent manner, the smooth muscle activity in strips from the Fallopian tube and the myometrium. Administered in combination, PHM and VIP had an additive effect and displayed the same efficacy as VIP alone, indicating that the peptides act via a common receptor.

Abstract
The aim of the present study was to elucidate the importance of the C-terminal amide group for the biological activity of vasoactive intestinal peptide (VIP). Two synthetic peptides lacking the amide group: VIP having a carboxyl group at the C-terminus and the intermediate biosynthetic precursor, glycine-extended VIP were compared with VIP itself regarding the ability to inhibit spontaneous activity in smooth muscle strips from rat stomach and human Fallopian tube. Both the glycine-extended VIP and VIP having a carboxyl group at the C-terminus caused a significant and dose-dependent inhibition of smooth muscle activity and displayed dose-response curves similar to VIP. The potencies of the VIP variants did not differ significantly from that of VIP. Thus, alpha-carboxyamidation of VIP is not a prerequisite for biological activity.

Abstract
By immunocytochemistry a number of the gut/brain peptides have been demonstrated in nerve fibers of the mammalian urogenital tract. These peptides are localized to large vesicles in nerve terminals of afferent fibers or efferent nerves innervating blood vessels, non-vascular smooth muscle, lining epithelium and glands. There is evidence that some neuropeptides (VIP, NPY) participate in the local non-cholinergic, non-adrenergic nervous control of smooth muscle activity and blood flow, while other peptides (substance P, CGRP) seem to be sensory transmitters. It is likely that impaired function of the peptidergic nerves is involved in sexual dysfunction such as male impotence.

Abstract
Forty-seven twin pregnancies among 3676 patients who had a genetic amniocentesis between 1973 and 1979, are reported. The detection rate of twins at the time of amniocentesis was 62 per cent. Five (17 per cent) of the 29 women with detected twin pregnancy aborted spontaneously, these are compared with 1 (6 per cent) of 18 women with undetected twin pregnancies and with 3 (3 per cent) of 93 singleton pregnancies, selected as controls as they had amniocentesis performed immediately before and after each of the twin mothers. Two of 9 (22 per cent) twin pregnancies, who had at least two punctures in at least one sac aborted, while 3 of 20 twin pregnancies with one puncture in each sac aborted (15 per cent). One of 18 (6 per cent) twin pregnancies, where only one sac was punctured, because the twin pregnancies were undetected, aborted. Amniocentesis of both sacs in twin pregnancies seems associated with an increased risk of spontaneous abortion. The indications for amniocentesis in twin pregnancies should be critically evaluated.
