Composition chimique et contamination butyrique du lait : facteurs de variation dans le département de la Haute-Loire
Authors: COULON J.B. , LILAS J.P. 
Published: August 2020

145 exploitations laitières du département de la Haute-Loire utilisant de l’ensilage d’herbe ont fait l’objet d’une enquête détaillée concernant à la fois la structure de l’exploitation et du troupeau, les pratiques alimentaires et les conditions de traite et d’hygiène des animaux. Ces données ont été analysées en liaison avec les variables caractérisant la composition chimique du lait et sa contamination en spores butyriques. Les écarts observés d’une exploitation à l’autre pour ces variables sont importants : respectivement 6 et 5 g/l entre les étables extrêmes pour les taux butyreux et protéique à l’échelle de l’année, la contamination butyrique variant de 300 à 16 000 spores/l. Les écarts de composition chimique sont principalement expliqués par les 3 facteurs suivants : type de ration de base, race des animaux et période de vêlage. Les écarts de contamination butyrique sont d’abord liés au type de ration de base utilisé (importance de l’ensilage d’herbe dans la ration) et à la propreté des animaux et des bâtiments. Peu d’exploitations appliquent l’ensemble des précautions nécessaires à l’obtention d’un lait peu contaminé en spores butyriques.

Published: August 2020

Cinq essais consécutifs ont été réalisés dans un dispositif d’élevage en extérieur comprenant 12 parquets de 15 oies et 5 jars (race landaise) afin de déterminer le besoin énergétique de ces animaux et les effets sur les performances de différentes concentrations énergétiques de l’aliment (de 2100 à 2800 kcal Energie Métabolisable/ kg). ). Le besoin énergétique journalier est de 800-850 kcal E M par oie « servie » (avec 1/3 jars) en saison normale et peut-être plus proche de 900 kcal E M en hiver très froid. Distribués à volonté, les régimes les plus concentrés sont défavorables à la reproduction, l’oie adulte régulant mal son ingéré énergétique en fonction de la teneur du régime. A l’inverse, dès lors qu’ils sont rationnés pour assurer strictement le besoin, les régimes « haute-énergie » permettent une amélioration de la fertilité (+ 7 à + 20 %) et une importante économie d’aliment (- 20 %). Cette pratique semble favoriser également la suppression de verdure fraîche dont l’apport peut représenter une contrainte lorsque l’oie n’a plus accès à des parcours.
Quel est l’impact économique d’une mauvaise fertilité chez la vache laitière ?
Authors: BOICHARD D. 
Published: August 2020

L’importance économique de la fertilité chez la vache laitière est estimée par modélisation. La fertilité est mesurée par le taux de conception moyen de l’élevage. Un modèle est tout d’abord construit pour déterminer l’espérance de revenu prévisionnel d’une vache, conditionnellement au taux de conception moyen de l’élevage. Cette espérance est maximisée par programmation dynamique, méthode permettant d’optimiser la conduite du troupeau. Le coût marginal d’une baisse du taux de conception est ensuite estimé par la différence entre les espérances de revenu prévisionnel d’une génisse prête à mettre bas, rapportée à la différence entre les taux de conception correspondants. L’estimation obtenue est minimale et n’inclut pas l’effet d’une éventuelle conduite non optimale. Elle est globale et intègre toutes les conséquences de la baisse de fertilité sur le taux de réforme, sur les lactations en cours et futures, ainsi que les frais immédiats. Le coût marginal ainsi déterminé est assez stable et ne dépend que de deux types de paramètres : il diminue lorsque la fertilité moyenne de la population augmente ou lorsque les conditions de renouvellement sont plus favorables (valeur à la réforme élevée, valeur d’une génisse de renouvellement faible). Dans les conditions françaises actuelles, la valeur de 1 point de taux de conception est comprise entre 10 et 20 FF par vache et par an selon ces paramètres.

Authors: Setyoningsih Setyoningsih 
Published: August 2020

Learning language is considered as learning its culture since language is part of culture. This article talks about the use of novel as one of literature to learn culture of other countries. The object of the study is a novel Not Without my Daughter (NW) by William Hoffer and Betty Mahmoody which is based on the true story of Betty Mahmoody, an American woman who was trapped in Iran society with her daughter. This novel is chosen because it reflects the social and cultural conditions of people, who come into contact with other cultures. The analysis was carried out through the following process i.e. (1) categorizing the data; (2) interpreting the data; (3) drawing conclusion. The result shows that cultural conflicts occurred because of friction of different cultures between Betty’s cultures, in this case America, and Iran culture. The cultural aspects causing conflicts found in NW were belief, custom and habit, uses of time, law, dress and body language. By analyzing cultural conflict in the novel, students can get a better understanding of other cultures and increase their cultural awareness.

Published: August 2020

Case:
Isolated popliteus tendon avulsion is an extremely rare injury with no consensus in the literature, regarding the therapeutic approach. In our case, the patient presented with rotational instability of the knee, and he was treated surgically. A fully arthroscopic technique with suture anchors was used, and this is the first report of such a repair in the literature. Knee stability was successfully restored, and the patient remains asymptomatic 2 years postoperatively.

Conclusion:
Isolated popliteus tendon avulsion can result in knee instability. Arthroscopic repair with suture anchors is an efficient way of treatment.

Published: August 2020

Background:
The sagittal-plane curvatures of the human spine are the consequence of evolution from quadrupedalism to bipedalism and are needed to maintain the center of mass of the body within the base of support in the bipedal position. Lumbar degenerative disorders can lead to a decrease in lumbar lordosis and thereby affect overall alignment of the spine. However, there is not yet enough direct evidence that surgical restoration of spinal malalignment would lead to a better clinical outcome. Therefore, the aim of this study was to assess the correlation between patient-reported outcomes and actual obtained spinal sagittal alignment in adult patients with lumbar degenerative disorders who underwent surgical treatment.

Methods:
A comprehensive literature search was conducted through databases (PubMed, Cochrane, Web of Science, and Embase). The last search was in November 2018. Risk of bias was assessed with the Newcastle-Ottawa quality assessment scale. A meta-regression analysis was performed.

Results:
Of 2,024 unique articles in the original search, 34 articles with 973 patients were included. All studies were either retrospective or prospective cohort studies; no randomized controlled trials were available. A total of 54 relations between preoperative-to-postoperative improvement in patient-reported outcome measures (PROMs) and radiographic spinopelvic parameters were found, of which 20 were eligible for meta-regression analysis. Of these, 2 correlations were significant: pelvic tilt (PT) versus Oswestry Disability Index (ODI) (p = 0.009) and PT versus visual analog scale (VAS) pain (p = 0.008).

Conclusions:
On the basis of the current literature, lower PT was significantly correlated with improved ODI and VAS pain in patients with sagittal malalignment caused by lumbar degenerative disorders that were treated with surgical correction of the sagittal balance.

Abstract
Background: The Prevalence of myopia is increasing in China. This study aimed to explore the distribution of spherical equivalent (SE) and its association with age, body mass index (BMI), gender in a non-myopic Chinese children population aged 6 to 12 years. Methods: A total of 6362 students were recruited for ophthalmological investigation. Demographic and myopia related behavioral information was collected. SE value was measured by the Topcon RM-8900 or KR-800autorefractors. Potential independent risk factors were determined with Odds Ratio (OR) and 95% Confidence Interval (CI) by logistic regression analysis. We further constructed the nomogram model to predict future onset of myopia.Results: Among the study population, 3900 (61.3%) were non-myopic. The prevalence of myopia is 38.0% for boys and 39.5% for girls. The average SE values were 0.50±0.70 D for boys and 0.60±0.80 D for girls. The mean SE values decreased with age, and the value of height and BMI took on a stable trend. Threshold values for myopia varied across age groups and gender. Paternal myopia (OR: 1.22, 95%CI: 1.01-1.48), near-work activities on weekends (2.56, 1.17-5.61), and outdoor activities (0.68, 0.54-0.86) were associated with potential myopic in students. Conclusion: A series of age-gender based SE threshold values were established to predict myopia in Chinese children aged 6 to 12 years. High risk factors for myopia included paternal myopia, near-work activities on weekends, and outdoor activities. Countermeasures are encouraged to reverse the increasing trend of myopia in children.

Abstract
Background: Ankylosing spondylitis (AS)is a chronic inflammatory disorder involving the sacroiliac joints, that could lead to disability due to the failure of timely treatment. Therefore, early diagnosis is essential to for AS treatment. The lymphocyte-to-monocyte ratio (LMR) is an indicator of disease progression. However, its role in AS remains unclear. The aim of this study was to investigate the role of LMR in AS diagnosis, disease activity classification and sacroiliitis staging. Methods: Seventy-eight AS patients and 78 sex and age matched healthy controls (HCs) were enrolled in this study. The diagnosis of AS was performed according to the New York criteria or the Assessment of SpondyloArthritis international Society (ASAS) classification criteria, whereas the staging of sacroiliitis in AS patients was determined by X-ray examination. Comparisons of LMR levels between groups were performed using t test. Pearson or Spearman correlation analysis were used to assess correlations between LMR and other indicators. Receiver operating characteristic (ROC) curves were used to determine the role of LMR in the diagnosis of AS.Results: Higher neutrophil-to-lymphocyte ratio(NLR), red blood cell distribution width(RDW), platelet-to-lymphocyte ratio(PLR), mean platelet volume(MPV), erythrocyte sedimentation rate (ESR), and C-reactive protein(CRP) levels and lower red blood cell (RBC), hemoglobin (Hb), Hematocrit (Hct), LMR, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and albumin/globulin (A/G) levels were noted in AS patients compared to HCs. Positive correlations were observed between LMR and RBC, Hb, Hct and A/G, whereas negative correlations were found between LMR and NLR, PLR, AST, and TBIL (P< 0.05). ROC curves showed that the area under the curve(AUC) for LMR in the diagnosis of ankylosing spondylitis was 0.803 (95% CI =0.734-0.872) with a sensitivity and specificity of 62.8% and 87.2%, respectively, and the AUC (95% CI) for the combination of ESR, CRP and LMR was 0.975 (0.948-1.000) with a sensitivity and specificity of 94.9% and 97.4%, respectively. LMR levels were lower (P<0.05) and significant differences in LMR values were observed among different stages (P<0.05). Conclusions: Our study suggested that LMR could be an important inflammatory marker that can be used to diagnosis AS and identify disease activity and X-ray stage of sacroiliitis.
Orthogonal Approach to Independent Component Analysis Using Quaternionic Factorization
Authors: Borowicz Adam 
Published: August 2020

Abstract
Independent component analysis (ICA) is a popular technique for demixing multi-channel data. The performance of a typical ICA algorithm strongly depends on the presence of additive noise, the actual distribution of source signals, and the estimated number of non-Gaussian components. Often a linear mixing model is assumed and source signals are extracted by data whitening followed by a sequence of plane (Jacobi) rotations. In this article, we develop a novel algorithm, based on the quaternionic factorization of rotation matrices and the Newton-Raphson iterative scheme. Unlike conventional rotational techniques such as the JADE algorithm, our method exploits $4 \times 4$ rotation matrices and uses approximate negentropy as a contrast function. Consequently, the proposed method can be adjusted to a given data distribution (e.g. super-Gaussians) by selecting a suitable non-linear function that approximates the negentropy. Compared to the widely-used, the symmetric FastICA algorithm, the proposed method does not require an orthogonalization step and is more accurate in the presence of multiple Gaussian sources.

Published: August 2020

Abstract
Background Left ventricular hypertrophy (LVH), defined by the left ventricular mass index (LVMI), is highly prevalent in hemodialysis patients and a strong independent predictor of cardiovascular events. Compared to cardiac magnetic resonance imaging (CMR), echocardiography tends to overestimate the LVMI. Here, we evaluate the diagnostic performance of transthoracic echocardiography (TTE) compared to CMR regarding the assessment of LVMI in hemodialysis patients.MethodsTTR and CMR data for 95 hemodialysis patients who participated in the MiREnDa trial were analyzed. The LVMI was calculated by two-dimensional (2D) TTE-guided M-mode measurements employing the American Society of Echocardiography (ASE) and Teichholz (Th) formulas, which were compared to the reference method, CMR.ResultsLVH was present in 44% of patients based on LVMI measured by CMR. LVMI measured by echocardiography correlated moderately with CMR, ASE: r=0.44 (0.34-0.62); Th: r=0.44(0.32-0.62). Compared to CMR, both echocardiographic formulas overestimated LVMI (mean ∆LVMI (ASE-CMR): 19.5±19.48 g/m2, p<0.001; mean ∆LVMI (Th-CMR): 15.9±15.89 g/m2, p<0.001). We found greater LVMI overestimation in patients with LVH using the ASE formula compared to the Th formula. Stratification of patients into CMR LVMI quartiles showed a continuous decrease in ∆LVMI with increasing CMR LVMI quartiles for the Th formula (p<0.001) but not for the ASE formula (p=0.772). Bland-Altman analysis showed that the Th formula had a constant bias independent of LVMI. Both methods had good discrimination ability for the detection of LVH (ROC-AUC: 0.819 (0.737-0.901) and 0.808 (0.723-0.892) for Th and ASE, respectively).ConclusionsThe ASE and Th formulas overestimate LVMI in hemodialysis patients. However, the overestimation is less with the Th formula, particularly with increasing LVMI. The results suggest that the Th formula should be preferred for measurement of LVMI in chronic hemodialysis patients.Trial registrationThe data was derived from the following clinical trial: NCT01691053, registered on 19 September 2012 before enrollment of the first participant, https://clinicaltrials.gov/ct2/show/NCT01691053?term=NCT01691053&draw=2&rank=1.

Published: August 2020

Abstract
Background: The objectives of this study were to determine for the first time, in Morocco, the nasal carriage rate, antimicrobial susceptibility profiles and virulence genes of Staphylococcus. aureus isolated from animals and breeders in close contact.Methods: From 2015 to 2016, 421 nasal swab samples were collected from 26 different livestock areas in Tangier. Antimicrobial susceptibility phenotypes were determined by disk diffusion according to EUCAST 2015. The presence of nuc, mecA, mecC, lukS/F-PV, and tst genes were determined by Polymerase Chain Reaction (PCR) for all isolates. Results: The overall S. aureus nasal carriage rate was low in animals (9.97%) and high in breeders (60%) with a statistically significant difference, (OR= 13.536; 95% CI = 7.070- 25.912; p< 0.001). In general, S. aureus strains were susceptible to the majority of antibiotics and the highest resistance rates were found against tetracycline (16.7% in animals and 10% in breeders). No Methicillin-Resistant S. aureus (MRSA) was detected in animals and breeders. A high rate of tst and lukS/F-PV genes has been recovered only from animals (11.9% and 16.7%, respectively).Conclusion: Despite the lower rate of nasal carriage of S. aureus and the absence of MRSA strains in our study, S. aureus strains harbored a higher frequency of tst and lukS/F-PV virulence genes, which is associated to an increased risk of infection dissemination in humans. This highlights the need for further larger and multi-center studies to better define the transmission of the pathogenic S. aureus between livestock, environment, and humans.

Published: August 2020

Abstract
Background: Individuals with major depressive disorder (MDD) have a high suicide risk. Some evidence suggests that uric acid (UA) may be involved in the pathophysiology of MDD. The purpose of this study was to evaluate whether serum UA levels were associated with suicide risk in MDD patients.Methods: One hundred four female patients with MDD (52 patients with suicide risk and 52 patients without suicide risk) and 52 healthy individuals were included in this study. The suicide risk was evaluated by Mini International Neuropsychiatric Interview (M.I.N.I.). Fasting serum levels of UA, as well as glucose, lipid and renal function indicators were measured.Results: Serum UA levels in MDD patients with suicide risk (245.01 ± 55.44 μmol/L) were significantly lower than those in MDD patients without suicide risk (274.17 ± 72.65 μmol/L) (p = 0.017) and healthy controls (271.42 ± 55.25 μmol/L) (p = 0.030). There was no difference in serum UA levels between the MDD patients without suicide risk and healthy controls (p = 0.821). Binary logistic regression analysis revealed a significant relationship between suicide risk and decreased serum UA levels (OR = 0.989, p = 0.010) in MDD patients.Conclusion: Decreased serum UA levels were associated with suicide risk in MDD patients. Purinergic system dysfunction may be involved in the neurobiological basis of suicide risk in these patients.

Published: August 2020

Abstract
Background: Identification of effective diagnostic and prognostic biomarkers of cancer is necessary for improving precision medicine. Long non-coding RNAs (lncRNAs) play an important regulatory role in tumor initiation and progression. The lncRNA LOC284454 is distinctly expressed in various head and neck cancers (HNCs), as demonstrated by our previous bioinformatics analysis. However, the expression levels and functions of LOC284454 in cancer are still unclear.Methods: We investigated the dysregulation of lncRNAs in HNCs using the GEO database and found that LOC284454 was highly expressed in HNCs. Serum samples from 212 patients with HNCs and 121 normal controls were included in this biomarker study. We measured the expression of LOC284454 in the sera of HNC patients and normal controls using RT-qPCR. Receiver operating characteristics (ROC) analysis is an important statistical method that is widely used in clinical diagnosis and disease screening. ROC was used to analyze the clinical value of LOC284454 in the early diagnosis of HNCs.Results: LOC284454 was significantly upregulated in the sera of patients with nasopharyngeal carcinoma, oral cancer, and thyroid cancer. LOC284454 upregulation had good clinical diagnostic value in these cancers, as evaluated by area under the ROC curve values of 0.931, 0.698, and 0.834, respectively.Conclusions:LOC284454 may be a valuable serum biomarker for HNCs facilitating the early diagnosis of malignant cancers. Further studies are needed to elucidate the mechanisms underlying the involvement of LOC284454 in HNCs. This study provides the first evidence that LOC284454 may be a serum biomarker for HNCs.
