Abstract
Ductal carcinomas in situ (DCIS) of the breast account for 85% to 90% of breast cancer in situ. Current recommendations for the management of DCIS in France are based on surgical excision of the lesions, lumpectomy in healthy margins (margins of excision≥2mm) or mastectomy in case of extensive lesions. Radiation therapy is recommended after conservative surgical treatment. However, it seems relevant for some patients to discuss the benefit of a therapeutic de-escalation. Indeed, it has been reported that radiotherapy has no major impact on overall survival and that its interest could be discussed in the low-risk situations of invasive recurrence for which surgery alone could be sufficient, subject to sufficient margins. These questions call for the precise definition of low risk populations and to clarify the importance of taking into account decision support tools and new molecular markers. The place of scores like that of the University of Southern California - Van Nuys, and that of genomic tests such as the Oncotype test© DX DCIS (DCIS score) need to be specified. The expected results of several prospective studies could go in the direction of a significant therapeutic de-escalation for the management of DCIS in the years to come. In the meantime, however, it is advisable to remain cautious and the inclusion of patients in clinical trials should be favored.

Abstract
OBJECTIVES To evaluate the value of high-risk HPV (HR HPV) testing in screening and post-treatment follow-up of high-grade squamous intraepithelial cervical lesions (HSIL). METHODS A systematic review of the literature from 2000 to 2019 was conducted including the following keywords: "human papilloma virus", "HPV testing", "cervical squamous intraepithelial lesion", "cervical cancer". RESULT Numerous recent randomized studies and meta-analyzes have concordant results in favor of HR HPV superiority over cervical smear in the screening and post-treatment monitoring of HSIL. In screening, the sensitivity of the HR HPV tests is 63% to 98% whereas that of the cervical smear is only 38% to 65% for the detection of HSIL+ (HSIL and invasive cancers). A negative HR HPV test is associated with less than 5% risk of LIEHG+at 6 years. In addition, after removal of a LIEHG, HR HPV tests have a sensitivity>90% and specificity>80% to predict treatment failure. After surgicale exision, a negative HR HPV test is associated with a risk of failure<2% (negative predictive value of 98%), and 12-25% if it is positive. CONCLUSIONS HR HPV tests are effective, allowing early detection of LIEHG+ identification of low-risk women in case of negative test, and a prediction of the risk of failure after treatment.

Abstract
The fertility sparing management of endometrial cancer and atypical hyperplasia concern women in childbearing age with stage 1, grade 1, endometrioid adenocarcinoma confined to endometrium or atypical hyperplasia (simple or complex). These pathologies affecting more frequently postmenopausal women, the number of people involved is relatively low. The main risk factor is hyperestrogenism and these patients often present a history of infertility with a desire for pregnancy. The recommendations for this conservative management are scarce and unclear. The national observatory in the gynecology and obstetrics department of Bichat hospital gives expert advice to help doctors and patients concerned. We present a type of conservative management based on the expertise of the national observatory. Rigorous pre-therapeutic assessment must first be made to avoid missing a more advanced lesion. Hormone therapy is then started to obtain complete remission. In case of remission, fast achieving pregnancy is advised, and the use of assisted reproductive therapy is possible if necessary. Monitoring by hysteroscopy and histological examination is essential during the treatment. Hysterectomy is the last time the conservative management. It is motivated by the risk of recurrence and progression. The probability of remission after conservative treatment is estimated at 78.0 % at 12 months, the probability of recurrence at 29.2 % at 24 months, and the risk of progression at 15 % (stage 1A with myometrial invasion or more on the hysterectomy specimen). In terms of fertility, 32 % of women get at least one pregnancy.

Abstract
One third of patients with critical limb ischemia (CLI) has below the knee lesions and requires a restoration of direct blood flow into the foot. However, many of these patients are ineligible for open surgery. The primary goals thus become pain relief and limb salvage over patency. The angiosome concept helps determine the target artery to treat in priority. The endovascular approach has decreased morbidity and mortality rates compared to distal bypass surgery; while subintimal retrograde, trans-collateral and loop techniques push the limits of open surgery by reopening the plantar arch, thereby improving run-off. Early restenosis phenomena after angioplasty have been improved by the use of - limus drug eluting balloons and balloon expandable stents in case of flow limiting dissection or recoil with increased limb salvage rates. Moreover, drug-eluting stents have been proposed, and allow a reduction in reintervention and in-stent restenosis rates in short lesions; however, results on amputation rates or survival are limited. Vessel preparation is a key to overcoming some current limitations, including atherectomy, which increases technical success rates and reduces restenosis rates, especially in calcified lesions, chronic total occlusions and restenosis. These advanced techniques in distal endovascular revascularization have revolutionized limb salvage and support the interest of an endovascular first approach in CLI treatment.

Abstract
The CACH/VWM syndrome is an autosomal recessive leukodystrophy characterized by a broad spectrum of clinical presentations and by diffuse cavitary degeneration of the white matter on MRI. Mutations responsible for this disorder are missense or frameshift mutations occurring in the five genes (EIF2B1-5) that encode the translation eukaryotic initiation factor eIF2B. We found that a patient with infantile CACH/VWM carries a mutation in the acceptor splice site of EIF2B5 exon 6. In lymphoblastoid cells of the patient, we detected an abnormal EIF2B5 transcript in which exon 6 was absent, however, the predicted protein product lacking part of the non-catalytic domain encoded by exon 6 was not detected. The eIF2B GEF activity was severely decreased. These data support the importance of the non-catalytic domain of the eIF2Bepsilon subunit in the eIF2B complex formation and activity.

Abstract
Four lactating Holstein cows fitted with ruminal and duodenal cannulas were used in a 4 x 4 Latin square design to determine the effects of feeding micronized and extruded flaxseed on milk composition and blood profile in late lactation. Four diets were formulated: a control (C) diet with no flaxseed, a raw flaxseed (RF) diet, a micronized flaxseed (MF) diet, and an extruded flaxseed (EF) diet. Flaxseed diets contained 12.6% flax-seed (dry matter basis). Experimental periods consisted of 21 d of diet adaptation and 7 d of data collection. Feeding flaxseed reduced milk yield and energy-corrected milk by 1.8 and 1.4 kg/d, respectively. Yields of milk protein and casein were also lower for cows fed flaxseed diets than for those fed the C diet. Milk yield (1.6 kg/d) and milk fat percentage (0.4 percentage unit) were lower for cows fed EF than those fed MF. Plasma cholesterol and nonesterified fatty acid concentrations were higher for cows fed flaxseed diets relative to those fed the C diet. Flaxseed supplementation decreased plasma concentrations of medium-chain (MCFA) and saturated (SFA) fatty acids and increased concentrations of long-chain (LCFA) and monounsaturated fatty acids. Feeding flaxseed reduced the concentrations of short-chain fatty acids (SCFA), MCFA, and SFA in milk fat. Consequently, concentrations of LCFA and unsaturated fatty acids were higher for cows fed flaxseed diets than for those fed the C diet. Flaxseed supplementation increased average concentrations of C(18:3) and conjugated linoleic acid by 152 and 68%, respectively. Micronization increased C(18:3) level, and extrusion reduced concentrations of SCFA and SFA in milk. It was concluded that feeding raw or heated flaxseed to dairy cows alters blood and milk fatty acid composition. Feeding extruded flaxseed relative to raw or micronized flaxseed had negative effects on milk yield and milk composition.

Abstract
Four lactating Holstein cows fitted with ruminal and duodenal cannulae were used in a 4 × 4 Latin square study to determine the effects of feeding micronized and extruded flaxseed on ruminal biohydrogenation (BH) and digestibility of fatty acids (FA) in the gastrointestinal tract. Four diets were formulated: a control diet with no flaxseed (C); a raw flaxseed diet (RF); a micronized flaxseed diet (MF); and an extruded flaxseed diet (EF). Flaxseed diets contained 126 g kg-1 flaxseed (dry matter basis). Experimental periods (n = 4) consisted of 21 d of diet adaptation and 7 d of data collection. Flaxseed supplementation increased (P < 0.05) intake of individual long-chain FA, reduced (P < 0.05) ruminal BH of total unsaturated C18, and increased (P < 0.05) duodenal flow of individual long-chain FA except for C18:2. Feeding flaxseed increased (P < 0.05) post-ruminal digestibility of C18:1, C18:2, and C18:3 and total tract digestibility of C16:0, C18:2, C18:3, and of total long-chain FA. Heat treatment had no effect on ruminal BH, duodenal flow and digestibility of unsaturated FA. Ruminal BH of C18:3 was higher (P < 0.05), while the duodenal flow of C18:3 was lower (P < 0.05) for cows fed EF than for those fed MF. Intake and duodenal flow of C16:0 were higher (P < 0.05) for cows fed MF relative to those fed EF. It was concluded that inclusion of flaxseed in dairy cow diets increased duodenal flow of polyunsaturated FA. However, heat treatments were not effective in protecting unsaturated FA from ruminal BH.

Abstract
Four lactating Holstein cows with ruminal and duo-denal cannulas were used in a 4 x 4 latin square design to determine the effects of feeding heat-treated flaxseed on ruminal fermentation and site and extent of nutrient utilization. Four diets were formulated: a control diet with no flaxseed, a raw flaxseed diet (RF), a micronized flaxseed diet (MF), and an extruded flaxseed diet (EF). Flaxseed diets contained 12.6% flaxseed (dry matter [DM] basis). Ruminal pH, NH3 N, and total concentration of volatile fatty acids were not affected by dietary treatments. However, feeding flaxseed decreased the molar proportion of acetate and increased that of propionate. Flaxseed supplementation had no effect on ruminal digestion of DM, organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), fatty acids (FA), and gross energy. However, ruminal digestion of acid detergent fiber (ADF) was lower for cows fed the flaxseed diets than for cows fed the control diet. Feeding flaxseed tended to increase post-ruminal and total tract digestibilities of DM, OM, NDF, and gross energy. Feeding heat-treated flaxseed diets relative to RF had no effect on ruminal, post-ruminal, and total tract nutrient digestibilities. Cows fed EF had higher ruminal and lower post-ruminal digestibilities of DM, OM, ADF, CP, and FA than cows fed MF. However, total tract digestibilities were similar for the 2 heat treatments. It was concluded that flaxseed supplementation improved total tract nutrient utilization with no adverse effects on ruminal fermentation. Extrusion failed to protect flaxseed from ruminal digestion. However, micronization can be used to increase the ruminal undegraded protein value of flaxseed.

Abstract
A study was conducted to determine the effects of extrusion on ruminal, post-ruminal and whole tract digestibility of flaxseed. Extrusion was performed at 155 degrees C with a residence time of 43 s. Two non-lactating Holstein cows fitted with ruminal and duodenal cannulas were used in a randomized complete block design. Results showed that extruded flaxseed had higher (P < 0.05) in situ soluble and lower (P < 0.05) slowly degradable DM and CP fractions than unheated flaxseed. Extrusion increased (P < 0.05) ruminal DM and CP degradability of flaxseed by 7 and 13%, respectively. Ruminal undegraded DM, CP and NDF were all lower (P < 0.05) for extruded flaxseed than for unheated flaxseed. Extrusion increased (P < 0.05) ruminal degradability and reduced (P < 0.05) post-ruminal availability of most amino acids of flaxseed. Whole tract digestibility of DM, CP, NDF and amino acids were higher (P < 0.05) for extruded than for unheated flaxseed. It was concluded that extrusion under the conditions used in the present experiment increases ruminal and whole tract nutrient degradabilities of flaxseed and therefore was ineffective in increasing the post-ruminal supply of amino acids from flaxseed.
