to untreated cows. This work provides initial evidence for the safety and efficacy of an allogenic MSC-based intramammary therapy for the treatment of bovine mastitis.Colorectal cancer (CRC) is the most common type cancers in the world. CRC occurs sporadically in the majority of cases, indicating the predominant cause of the disease are environmental factors. Diet-induced changes in gut-microbiome are recently supposed to contribute on epidemics of CRC. This study was aimed to investigate the association of metagenomics and metabolomics in gut extracellular vesicles (EVs) of CRC and healthy subjects. A total of 40 healthy volunteers and 32 patients with CRC were enrolled in this study. Metagenomic profiling by sequencing 16 S rDNA was performed for assessing microbial codiversity. We explored the small molecule metabolites using gas chromatography-time-of-flight mass spectrometry. In total, stool EVs were prepared from 40 healthy volunteers and 32 patients with CRC. Metagenomic profiling demonstrated that bacterial phyla, particularly of Firmicutes and Proteobacteria, were significantly altered in patients with colorectal cancer. Through metabolomics profiling, we determined seven amino acids, four carboxylic acids, and four fatty acids; including short-chain to long chain fatty acids that altered in the disease group. Binary logistic regression was further tested to evaluate the diagnostic performance. In summary, the present findings suggest that gut flora dysbiosis may result in alternation of amino acid metabolism, which may be correlated with the pathogenesis of CRC.We evaluated the changes in visual field mean deviation (VF MD) and retinal nerve fibre layer (RNFL) thickness in glaucoma patients undergoing trabeculectomy. One hundred patients were examined with VF and spectral-domain optical coherence tomography (OCT) before trabeculectomy and 4 follow-up visits over one year. Linear mixed models were used to investigate factors associated with VF and RNFL. VF improved during the first 3 months of follow-up (2.55 ± 1.06 dB/year) and worsened at later visits (-1.14 ± 0.29 dB/year). RNFL thickness reduced by -4.21 ± 0.25 µm/year from 1st month of follow-up. Eyes with an absence of initial VF improvement (β = 0.64; 0.30-0.98), RNFL thinning (β = 0.15; 0.08-0.23), increasing intraocular pressure (IOP; β = -0.11; -0.18 to -0.03) and severe glaucoma (β = -10.82; -13.61 to -8.02) were associated with VF deterioration. Eyes with VF deterioration (β = 0.19; 0.08-0.29), increasing IOP (β = -0.09; -0.17 to -0.01), and moderate (β = -6.33; -12.17 to -0.49) or severe glaucoma (β = -19.58; -24.63 to -14.52) were associated with RNFL thinning. Changes in RNFL structure and function occur over a 1-year follow-up period after trabeculectomy. Early VF improvement is more likely to occur in patients with mild/moderate glaucoma, whereas those with severe glaucoma show greater decline over one year. Our findings indicate that progression is observable using OCT, even in late-stage glaucoma.This study evaluated stereopsis and other visual functions in patients with idiopathic macular hole (MH), and sought to identify vision-related parameters that affect stereopsis. In this prospective, consecutive, comparative study, 39 eyes of 39 patients with unilateral idiopathic MH were included. At baseline and at 6 months after MH surgery, we evaluated stereopsis, with the Titmus stereo test (TST) and TNO stereotest (TNO), best-corrected visual acuity (BCVA), letter contrast sensitivity, severity of metamorphopsia, as assessed using M-CHARTS, and extent of aniseikonia, by the new aniseikonia test. Preoperative stereopsis (log) in patients with MH were 2.72 ± 0.53 (range 1.9-4.1) in the TST and 2.82 ± 0.65 (range 1.8-3.9) in the TNO. Preoperative TST was significantly correlated with letter contrast sensitivity (p  less then  0.05), but not with the other visual functions. SLF1081851 TNO showed significant correlation with letter contrast sensitivity (p  less then  0.05) and aniseikonia (p  less then  0.005). Preoperative TNO was associated with aniseikonia by multivariate analysis (p  less then  0.005). MH surgery significantly improved stereopsis, BCVA, letter contrast sensitivity, metamorphopsia, and aniseikonia. Postoperative TST and TNO was significantly associated with BCVA by multivariate analysis. Deterioration of stereopsis in MH patients is associated with contrast sensitivity and the degree of aniseikonia.OBJECTIVE In preterm neonates fed human milk, fortification may be adjusted by (1) optimization, based on growth rate and serum nutrient analyses, or (2) individualization, based on serial milk nutrient analyses. The primary aim was to determine whether individualized plus optimized nutrition (experimental) improves velocity of weight gain and linear growth from birth to endpoint (36 weeks postmenstrual age or discharge) when compared with optimized nutrition alone (controls). STUDY DESIGN Double-blinded parallel group randomized trial in 120 neonates less then 29 weeks gestational age (GA) or less then 35 weeks and small for GA (birth weight  less then  10th centile). RESULT Weight-gain velocity (13.1 ± 2.1, n = 57 controls, vs. 13.0 ± 2.6 g kg-1 day-1, n = 59 experimental, P = 0.87), linear growth (0.9 ± 0.2, n = 55, vs. 0.9 ± 0.2 cm week-1, n = 52, P = 0.90) and frequency of weight/length disproportion (2% vs. 2%, P = 0.98) were similar in both groups. CONCLUSIONS Individualized plus optimized nutrition does not improve weight gain, linear growth, or weight/length disproportion at endpoint versus optimized nutrition alone.OBJECTIVE To measure the macronutrient content (MNC) of donor human milk labelled as 24 kcal/oz ("high-calorie DHM," hcDHM), compare to bank-labelled MNC, and examine variability of hcDHM MNC among milk banks. STUDY DESIGN MNC was measured with near-infrared spectroscopy for 75 convenience samples from five milk banks collected during September 2016-July 2017. Concordance of measured MNC with labelled values was evaluated using three different thresholds within ±20%, similar to FDA labelling standards for class II nutrients in foods; ±10%; and ±5%. RESULTS Protein and caloric content differed significantly between measured and labelled values and varied significantly among milk banks. Measured caloric content ranged from 16.50 to 30.27 kcal/oz, with 89.3% of hcDHM samples within ±20%, 58.7% within ±10%, and 18.7% within ±5% of labelled content. CONCLUSIONS MNC of hcDHM used in clinical practice shows variation that may result in differences from desired diet. The clinical implications of such differences are unexplored.
