In the general population, the construct of race is associated with disparities in cognitive aging. There are notable racial group disparities and inequities among people living with schizophrenia (PLWSz). Despite the salience of the construct of race in schizophrenia, there remains a knowledge gap about racial disparities in cognitive impairment among older adults in this vulnerable population. Our study uses mediation analysis to examine racial disparities in cognitive impairment among older adults with schizophrenia.We assess global cognition in PLWSz over age 55 with the Measurement and Treatment Research to Improve Cognition in Schizophrenia cognitive test battery in our "all-comer" sample (There was a Black/non-Black group racial disparity in global cognitive score (-2.8, 95% CI: -4.4, -1.3) after adjusting for confounding and interaction. This disparity was significantly mediated by years of education.There are notable racial disparities in cognitive impairment among older adults with schizophrenia; however, differences in cognitive scores between racial groups are mediated by level of education.Social determinants of health, particularly educational attainment, are important risk factors for cognitive impairment in PLWSz and should be considered by clinicians.

An important issue in the selection of dairy cattle today is the study of the relationship between hereditary factors that determine the types of proteins in milk. Casein is the main component of milk proteins and is represented by three fractions - alpha (CSN1S1), beta (CSN2) and kappa (CSN3). The content of individual fractions of casein depends on the breed of cows. Genetic variants of kappa-casein are associated with the quality of milk productivity of cows and greater suitability for use of milk for processing and production of cheese. The kappa-casein B allele is associated with the production of milk, the chemical composition of which is more favorable and the technological parameters are more suitable for cheese production. The aim of the work is to assess the genotype of breeding bulls by the kappa-casein gene, which were approved for use in Ukrainian farms in 2020. It was found that most breeding bulls that are approved for use are evaluated by the genotype of kappa-casein. Breeding bulls of Swiss and Jersey breeds have a higher frequency of homozygotes of explosives (100 and 86.2%, respectively). The frequency of allele distribution in the kappa-casein gene in bulls of different breeds was higher in animals of Schwyz (1.00), Jersey (0.931) and Montbeliard breeds (0.813). Among breeding bulls of Holstein breed, no significant difference in milk yield, milk fat and protein between animals of all studied genotypes by kappa-casein and average by breed (among bulls of the catalog) was found. Breeding bulls with the BB genotype had a significant difference with bulls of other genotypes in all studied traits. Therefore, the use of sperm products of bulls approved for use in 2020, with the genotype of explosives for kappa-casein will improve the economically useful traits of offspring, and will contribute to the desired genotype of cows. When choosing bulls, cheese makers should pay attention not only to protein and somatic cell count (SCS). It is also important to have a high percentage of BB cows in the herd

The mucus clearance system is the dominant mechanical host defense system of the human lung. Mucus is cleared from the lung by cilia and airflow, including both two-phase gas-liquid pumping and cough-dependent mechanisms, and mucus transport rates are heavily dependent on mucus concentration. Importantly, mucus transport rates are accurately predicted by the gel-on-brush model of the mucociliary apparatus from the relative osmotic moduli of the mucus and periciliary-glycocalyceal (PCL-G) layers. The fluid available to hydrate mucus is generated by transepithelial fluid transport. Feedback interactions between mucus concentrations and cilia beating, via purinergic signaling, coordinate Na+absorptive vs Cl−secretory rates to maintain mucus hydration in health. In disease, mucus becomes hyperconcentrated (dehydrated). Multiple mechanisms derange the ion transport pathways that normally hydrate mucus in muco-obstructive lung diseases, e.g., cystic fibrosis (CF), chronic obstructive pulmonary disease (COPD), non-CF bronchiectasis (NCFB), and primary ciliary dyskinesia (PCD). A key step in muco-obstructive disease pathogenesis is the osmotic compression of the mucus layer onto the airway surface with the formation of adherent mucus plaques and plugs, particularly in distal airways. Mucus plaques create locally hypoxic conditions and produce airflow obstruction, inflammation, infection, and, ultimately, airway wall damage. Therapies to clear adherent mucus with hydrating and mucolytic agents are rational, and strategies to develop these agents are reviewed.

The aim of this paper is to describe and analyze the main features and trends of the private-wage Youth Labour Market (YLM) in Chile between 2010-2019. The study uses a quantitative method research design to examine, in the first place, salary trends and socio-demographic and occupational characteristics of the YLM; and second, to analyze the numerical flexibility in terms of contracts, working hours, and outsourcing. The results suggest that the wage process of young people has stopped in the private sector. Furthermore, young workers have higher levels of numerical flexibility, lower wages, and are inserted in unskilled service occupations, despite having higher credentials than adults. The latter could be explained by labour segmentation mechanisms and the role that the youth labour market plays in the neoliberal economic order., El presente artículo tiene por objetivo describir y analizar las principales características y tendencias del mercado laboral juvenil (MLJ) asalariado privado en Chile para el periodo 2010-2019. Mediante un diseño metodológico cuantitativo descriptivo se examinan, en primer lugar, las tendencias de asalarización y principales características sociodemográficas y ocupacionales para 2010-2019; y segundo, las transformaciones en la flexibilidad numérica en términos de contratos, jornadas y subcontratación laboral. La evidencia sugiere que la asalarización del MLJ se ha detenido en el sector privado, en tanto, las personas jóvenes registran salarios más bajos, se insertan en ocupaciones de servicio no calificados, pese a tener mayores credenciales, y registran una mayor flexibilidad que las personas adultas. Lo último podría estar explicado por mecanismos de segmentación laboral y el rol que el propio MLJ juega en el funcionamiento del orden económico neoliberal.

Introduction The purpose of this study was to describe symptoms of problematic feeding in infants with tongue-tie, evaluate changes in non-nutritive suck measures before and after frenotomy, and examine tongue-tie severity with changes in non-nutritive suck patterning. Method Parents completed the Neonatal Eating Assessment Tool about infant feeding before frenotomy. Non-nutritive suck data were collected for 5 min before and after frenotomy. We used paired t-tests to compare non-nutritive suck measures pre- and post-frenotomy and linear regression evaluated the effect of tongue-tie severity and infant behavioral state on change in non-nutritive suck mechanics. Results Twenty-one infants had scores that met criteria for problematic feeding. The infant's non-nutritive suck amplitude (cmH2O) (p = .02) and non-nutritive burst duration (sec) (p = .03) decreased post-frenotomy. Discussion This study supports the need for additional research to better understand feeding problems and changes in non-nutritive suck amplitude and duration in infants with tongue-tie.

Emerging evidence shows that some Lactobacillus fermentum strains can contribute to the prevention and treatment of ulcerative colitis (UC). In this study, 105 isolates of L. fermentum strains were separated from fecal samples of populations in different regions in China and their draft genomes were sequenced. Pan-genomic and phylogenetic characterizations of these strains and four model strains (L. fermentum 3872, CECT5716, IFO3956 and VRI003) were performed. Phylogenetic analysis indicated that there was no significant adaptive evolution between the genomes of L. fermentum strains and the geographical location, sex, ethnicity and age of the hosts. Three L. fermentum strains (FWXBH115, FGDLZR121, and FXJCJ61) from different branches of the phylogenetic tree and strain type L. fermentum CECT5716 were selected and their anti-inflammatory and immune modulatory activities in a dextran sulphate sodium (DSS)-induced colitis mouse model were further investigated. Both L. fermentum FXJCJ61 and CECT5716 significantly alleviated UC by reducing all colitis-associated histological indices, maintaining mucosal integrity, and stimulating replenishment of short-chain fatty acids (SCFAs), while the other two strains failed to offer similar protection. The anti-inflammatory mechanisms of L. fermentum FXJCJ61 and CECT5716 were related to the inhibition of nuclear factor kappa-B (NF-κB) signaling pathway activation and enhancement of interleukin 10 (IL-10) production. Comparative genomic analysis of these strains identified candidate genes that may contribute to the anti-inflammatory effects of specific L. fermentum strains.

AIM Detection of possible predictive factors of endoscopic recurrence after ileocecal resection in Crohn's disease could be very beneficial for the individual adjustment of postoperative therapy. The aim of this study was to verify, whether immunohistochemical detection of calprotectin in resection margins is useful in diagnostics of endoscopic recurrence. METHODS In this study we included pediatric patients with Crohn's disease who underwent ileocecal resection, regardless of pre-operative or post-operative therapy (n=48). We collected laboratory, clinical, surgical, endoscopic and histopathological data at the time of surgery and at 6 months after surgery. The immunohistochemical staining of calprotectin antigen was performed on all paraffin blocks from the resection margins. RESULTS Out of 48 patients 52% had endoscopic recurrence in the anastomosis (defined by Rutgeerts score) within 6 months after surgery. The number of cells positive for calprotectin in the proximal resection margin was negatively associated with recurrence (P=0.008), as was the elevated level of total calprotectin (from both resection margins). There was no correlation of calprotectin in distal resection margin and endoscopic recurrence. Fecal calprotectin over 100 ug/g (P=0.0005) and high CRP (P

The aim of the present study was to determine correlations between udder skin surface temperatures and milk yield and estimated composition in dairy cows. The thermographic images of 34 Polish Holstein–Friesian black-and-white cows were taken in a milking parlor before and after milking. Partial correlation coefficients were calculated between the surface temperatures of the udder hind quarters and milk production traits controlling for age, parity, year, and milking time. Daily milk yield was weakly and nonsignificantly correlated with surface temperatures ( rp ranging from −0.19 to 0.21), except for the mean and maximum temperatures of the left hind quarter after milking ( rp = 0.40 and rp = 0.38, respectively). There were significant correlations of skin surface temperature with estimated fat content ( rp = −0.55 to 0.48), protein content ( rp = −0.39 to 0.42), fat yield ( rp = −0.42 to 0.54), and protein yield ( rp = 0.37 to 0.54). The estimated somatic cell count was significantly correlated with the minimum temperature ( rp = −0.54 to −0.36). The estimated urea content was significantly correlated with the minimum temperature ( rp = 0.52). A larger sample size is required in future research to confirm these preliminary results.

The gut microbiota has been suggested to influence neurodevelopment in rodents. Preliminary human studies have associated fecal microbiota composition with features of emotional and cognitive development as well as differences in thalamus-amygdala connectivity. Currently, microbiota-gut-brain axis studies cover heterogenous set of infant and child brain developmental phenotypes, while microbiota associations with more fine-grained aspects of brain development remain largely unknown. Here (N = 122, 53% boys), we investigated the associations between infant fecal microbiota composition and infant attention to emotional faces, as bias for faces is strong in infancy and deviations in early processing of emotional facial expressions may influence the trajectories of social-emotional development. The fecal microbiota composition was assessed at 2.5 months of age and analyzed with 16S rRNA gene sequencing. Attention to emotional faces was assessed with an age-appropriate face-distractor paradigm, using neutral, happy, fearful, and scrambled faces and salient distractors, at 8 months of age. We observed an association between a lower abundance of Bifidobacterium and a higher abundance of Clostridium with an increased "fear bias," that is, attention toward fearful versus happy/neutral faces. This data suggests an association between early microbiota and later fear bias, a well-established infant phenotype of emotionally directed attention. However, the clinical significance or causality of our findings remains to be assessed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

In response to the Institute on Minority Health and Health Disparities’ (NIMHD) new health disparities research framework, we call on the National Institutes of Health (NIH) to acknowledge Arabs in the United States as a health disparity population. Arab classification as White leads to their cultural invisibility and perpetuates a cycle of undocumented health disparities. We provide examples of how this contested identity reinforces challenges associated with identifying this population and contributes to enactments of structural violence and undocumented health disparities. Decades of research with Arabs in the United States provides consistent evidence that their health does not fit the health profile of White Americans and that Arabs do not benefit from Whiteness and White privilege associated with their White racial categorization. On the contrary, Arabs in the United States experience discrimination and health disparities that require urgent attention; this can be achieved only by identifying the population with a racial category other than White. We conclude with recommendations to NIH and NIMHD to revise their definition of health disparity populations to include Arabs in the United States.

Glutamic acid (Glu), an umami component in human milk, has been suggested to play an important role in the prevention of allergies and infections in infants, but the relationship between mothers' habitual diet and Glu in human milk is not clear. Therefore, we aimed to clarify the relationship between maternal dietary habits and Glu concentrations in durable milk during the first month postpartum in 41 lactating women using a cross-sectional prospective study. Metrics included habitual dietary intake at 1 month postpartum (Self-Reported Dietary History Questionnaire), Glu concentration in durable milk whey, and plasma at 1 month postpartum. There was no correlation between Glu concentration in plasma and durable milk Glu concentration at 1 month postpartum. Food items that were correlated with plasma and milk Glu concentrations were sparse in Glu or did not contain Glu; therefore, we could not determine the relationship between Glu concentrations in durable milk and maternal dietary intake. In addition, Glu concentration in durable milk was significantly higher among multipara than primipara and among mothers with a relatively high degree of physical activity. Although the study did not show that mothers' habitual dietary intake affected milk Glu, Glu concentrations in durable milk were approximately 30 times higher than those found in plasma. Further research is needed to clarify the relationship between individual factors and milk or plasma Glu.

Pseudomonas aeruginosa produces specific signalling molecules, 2-alkyl-4-quinolones (AQs) that are detectable in the sputum of adults with cystic fibrosis (CF) and who have pulmonary infection with this opportunistic pathogen. This study aimed to determine whether AQs could be detected in saliva of patients with CF and known infection with Pseudomonas aeruginosa. Saliva and sputum samples were obtained from 89 adults with CF and analyzed using liquid chromatography-tandem mass spectrometry. AQs were detected in 39/89 (43.8%) saliva samples and 70/77(90.9%) sputum samples. Salivary AQs had a sensitivity of 50% (95%CI; 37.8; 62.2), specificity of 100% (95%CI; 47.8; 100), when compared to a molecular microbiological measure of P. aeruginosa in sputum as measured using polymerase chain reaction. Specific AQs produced by P. aeruginosa can be detected in the saliva and warrant investigation as potential non-invasive biomarkers of pulmonary P. aeruginosa.

Background The paper is aimed at uncovering the mechanism of miR-204-5p in regulating inflammatory responses of human osteoarthritic synovial fibroblasts (SFs). Methods IL-1β-induced osteoarthritic SFs were established as an osteoarthritis (OA) cell model. The osteoarthritic SFs were accordingly transfected with mimics-miR-204-5p, inhibitors-miR-204-5 or FOXC1 siRNA. MTT tested the vitality of osteoarthritic SFs by analyzing the cell optical density. The expressions of miR-204-5p, FOXC1, TNF-α, IL-6, PGE2, MMP-1, MMP-13 and COX-2 in osteoarthritic SFs were measured by qRT-PCR, Western blotting and/or ELISA. The binding of miR-204-5p to FOXC1 was verified through luciferase reporter assay. The regulatory effect of miR-204-5p on FOXC1 was also tested in normal SFs. Results miR-204-5p was under-expressed and FOXC1 was over-expressed in osteoarthritic SFs. The expressions of FOXC1, TNF-α, IL-6, PGE2, MMP-1, MMP-13 and COX-2 were up-regulated in IL-1β-treated SFs. Up-regulation of miR-204-5p or down-regulation of FOXC1 suppressed the inflammatory responses of osteoarthritic SFs. miR-204-5p negatively regulated FOXC1 by being a sponge in osteoarthritic SFs as well as in normal SFs. Conclusion miR-204-5p down-regulates FOXC1 to ameliorate inflammation of SFs in OA.

Previous studies have shown that the gut microbiota of patients with acute myeloid leukemia (AML) is disrupted during induction chemotherapy; however, the durability of microbiota changes is unknown. This is an important knowledge gap, because reduced microbiota diversity at the time of stem cell transplantation weeks to months after the initial chemotherapy has been associated with higher mortality after transplantation. By sequencing the gut microbiota in 410 longitudinal stool samples from 52 patients with AML, we found that, during inpatient chemotherapy, the gut microbiota is stressed beyond its ability to recover its original state. Despite major reductions in antibiotic pressure and other disturbances to the microbiota after hospital discharge, the trajectory of microbiota recovery yields new communities that are highly dissimilar to baseline. This lasting shift in the gut microbiota is relevant for subsequent phases of curative therapy and is a potential target for novel microbiota protective/restorative interventions. This trial was registered at www.clinicaltrials.gov as #NCT03316456.

The aims of this study is to determine the quality of fresh cement of Landrace pigs diluted with natural diluent of green coconut water. The research was conducted at the Veterinary Reproduction Laboratory of FKKH Undana. Fresh semen of Landrace pigs was collected from male pigs that less than 3 years sexually mature and in healthy condition, then the semen quality was examined by macroscopic and microscopic evaluation. Only cement met the requirements, the proportion of spermatozoa motility not less than 70%, spermatozoa concentration not less than 200 million cells/ml and spermatozoa abnormality not more than 20%. After that, the semen was diluted by adding green coconut water and antibiotics according to the dilution formula. The results showed that semen diluted with natural green coconut was better and could be used as an alternative diluent with a higher of spermatozoa viability and motility (48.2% & 41.25%) compared to fresh semen with a shelf life of 20 hours.

A novel castor-oil-based and phosphorus-containing epoxy resin (flame-retardant epoxy resin (FREP)) and a curing agent – castor oil polybasic acid (AACO) – with high flame retardancy and flexibility were successfully synthesized. The chemical structures of FREP and AACO were characterized by Fourier transform infrared spectrometry (FTIR) and hydrogen-1 (1H) nuclear magnetic resonance spectroscopy. The epoxy resin components were prepared by using bisphenol A epoxy resin (diglycidyl ether of bisphenol A (DGEBA)) with different mass contents of FREP and AACO. DGEBA with 40 wt% FREP (FREP40) possessed a large limiting oxygen index of 29.3%. Cone calorimetry showed that the heat release and smoke production were reduced for both DGEBA with 20 wt% FREP (FREP20) and FREP40 in comparison with those of pure resin (FREP0), indicating that the smoke release and fire hazard of epoxy resin composites with FREP were reduced. Thermogravimetry–infrared spectroscopy suggested that the yields of toxic carbon monoxide (CO), carbon dioxide (CO2) and other pyrolysis products were significantly reduced. FTIR and X-ray photoelectron spectroscopy showed that FREP40 outperformed FREP0 in carbon-forming capacity. The introduction of FREP and AACO effectively increased the elongation at break of pure epoxy resins. FREP and AACO provide a promising strategy for synthesis of epoxy resins with excellent flame retardancy, smoke suppression and flexible performance.

Many dairy herds use automatic milking stations (AMS), with cows in large herds often having access to 2 or more AMS, and must choose between them when they go for milking. Individual cows acquire routines of either consistently using a specific milking box or consistently using any available milking box. Here, we hypothesized that the degree of use of the same milking box was an expression of preference, and quantified it as preference consistency score (PCS). The PCS was calculated as a ratio between the excess frequencies of the first choice over the base frequency of "not first choice" over 15-d segments of lactation. This ratio was 0 if all choices were taken equally, and became 1.0 if only the first choice was taken in all events. We investigated the consistency of milking box preference in 2 cohorts (one Holstein and one Jersey) across 6 commercial dairy herds in Denmark (n = 4,665 cows total). In addition to PCS, we recorded and analyzed associated milking and behavior traits, including a time profile index showing use of specific clock hours when cows were milked (Time_profile, based on excess use of specific clock hours), milking frequency, time spent in the milking box, and milk yield. Records from each milking event were condensed into 15-d segments based on days in milk. The data were analyzed using a linear mixed model, with random genetic and individual cow effects, to estimate heritability (h2), repeatability (t), and individual level correlations (ri) between traits. The average PCS was 0.43 and 0.41 in Holstein and Jersey, respectively, showing that cows developed routines for consistently using the same milking box; however, some cows had lower preference (i.e., greater flexibility in use). The Time_profile indicated that some cows were milked in a few hour-bins, whereas others were more flexible. The PCS and Time_profile traits had low heritability (h2, PCS/Time_profile = 0.07 ± 0.02/0.11 ± 0.02 Holstein, 0.13 ± 0.03/0.04 ± 0.02 Jersey) and moderate repeatability (t, PCS/Time_profile = 0.47/0.40 Holstein, 0.50/0.42 Jersey). The 2 traits were weakly correlated with each other (ri = 0.18 and 0.17), and were weakly correlated with milk yield (ri range: 0.0 to -0.10). However, the time profile was strongly correlated with milking frequency (ri range: -0.81 to -0.73), and was moderately correlated with daily box time (ri range: -0.43 to -0.35). In general, Holstein and Jersey parameter estimates were of similar size, and thus in good agreement. Overall, individual cows covered a broad spectrum of preference consistency, both regarding the use of specific milking boxes and time profiles, with these 2 traits representing different aspects or dimensions of milking behavior. The findings that some cows have strong preferences for specific AMS may be most useful in herd management and farm design. The weak correlation to milk yield indicated that yield minimally affected these 2 milking associated behavior traits. In conclusion, although the traits were repeatable, heritability was low; thus, genetic selection for milk yield might minimally affect these 2 traits.

[Background.] Unrelated cord blood (UCB) and haploidentical related donor transplantation using posttransplant cyclophosphamide (PTCy-haplo) have become alternative options to treat patients with hematological malignancies without a HLA-matched donor. [Methods.] We conducted a retrospective study using registry data from the Kyoto Stem Cell Transplantation Group for patients with hematological malignancies who received their first allogeneic hematopoietic cell transplantation using a single UCB unit (n = 460) or PTCy-haplo (N = 57) between 2013 and 2019. [Results.] We found that overall survival in the UCB group was comparable to that in the PTCy-haplo group (hazard ratio, 1.00; 95% confidence interval, 0.66-1.52), although neutrophil and platelet engraftment were significantly delayed. Nonrelapse mortality risk and the incidence of graft-versus-host disease in the UCB group were also comparable to those in the PTCy-haplo group. Although the relapse risk was similar between the UCB group and the PTCy-haplo group regardless of the disease risk, acute myeloid leukemia patients benefit from UCB transplant with a significantly lower relapse rate (hazard ratio, 0.38; 95% confidence interval, 0.18-0.76). [Conclusions.] UCB transplant gives outcomes comparable to PTCy-haplo transplant, and both UCB and PTCy-haplo units are suitable as alternative donor sources for patients without an HLA-matched sibling or unrelated donor.

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The objective of this review will be to evaluate the efficacy and safety of administering lactoferrin for the post‐operative management of term neonates, measured by the incidence of sepsis, mortality and duration of hospital stay. We aim to evaluate benefits and harms with the use of lactoferrin in individual gastrointestinal pathologies and specific lactoferrin product, if sufficient data are available.

BACKGROUND Chronic cough is a common symptom, addressed in the clinical setting by empirical treatment together with some laboratory investigations. Purpose of the present study is to investigate the value of testing eosinophilic cationic protein (ECP) serum levels combined with other diagnostic procedures and empirical treatment in the diagnostic workup of chronic cough. METHODS In this study, we evaluated 194 patients with chronic cough. No subject had received any anti-inflammatory treatment before clinical evaluation, and none was an active smoker. ECP was measured with a commercially available fluoroenzyme immunoassay and results were expressed as µg/L. RESULTS The analysis of variance showed that mean ECP level differs among the various diagnosis categories (p < 0.001). Mean ECP level was significantly higher in asthmatic patients, particularly in the active disease. CONCLUSIONS Serum ECP concentration could represent a useful biomarker in the clinical work-up of chronic cough, managing to differentiate asthma from other chronic disorders.

Breast milk is a complex biological fluid. Additionally to its nutritional impact, it contains diverse bioactive elements related to early metabolic programming and molecular structures, such as microRNA related to the epigenetic signaling process. Now, we know that human milk is not sterile and contains a significant diversity of microorganisms such as bacteria (bacterioma), viruses (viroma) and fungi (mycobiome), all of which integrate the concept of the human milk microbiota. Apparently the origin of this microbiota is found in the entero-mammary circulation, as well as in the retrograde circulation of the skin of the mammary gland, although it is speculated in what percentage the microbiota of the oral cavity of the infant contributes in a significant way. From a functional point of view, it has been shown the transfer of this microbiota to the infant's digestive tract, which is related to better digestive tolerance, lower frequency and intensity of dysfunctionalities of the brain-intestine-microbiota axis, and improved immunity, among others.La leche materna es un fluido biológico complejo, ya que además de nutrir, contiene diversos elementos bioactivos relacionados con el fenómeno de programación metabólica temprana e incluso contiene estructuras moleculares relacionadas con el proceso de señalización epigenética tales como los microARN. Ahora sabemos que la leche humana no es estéril y contiene una diversidad significativa de microorganismos tales como bacterias (bacterioma), virus (viroma) y hongos (micobioma), todo lo cual integra el concepto de microbiota de leche humana. Al parecer el origen de esta microbiota se encuentra en la circulación enteromamaria, así como en la circulación retrógrada de la piel de glándula mamaria, aunque se especula en qué porcentaje la microbiota de la cavidad bucal del lactante contribuye de forma significativa. Desde el punto de vista funcional, se ha demostrado transferencia de esta microbiota hacia el tubo digestivo del lactante, lo que se relaciona con una mejor tolerancia digestiva, menor frecuencia e intensidad de disfuncionalidades del eje cerebro-intestino-microbiota, y mejora de la inmunidad, entre otras.

Emerging research suggests that sleep contributes to racial disparities in cardiovascular disease (CVD). Racial/ethnic minorities are disproportionately affected by poor cardiovascular outcomes including obesity, hypertension and diabetes. Although circadian rhythms affect sleep patterns, few studies have examined disparities in circadian health or the contribution of circadian disparities to CVD. In this paper, we provide an overview of the relation between circadian health and CVD in the context of health disparities. We discuss (1) the current knowledge on racial disparities in circadian health; (2) social and environmental determinants of circadian health disparities; (3) the cardiovascular consequences of circadian disparities; and (4) future opportunities to advance the field of circadian disparities. In brief, our findings demonstrated that among a small literature, racial minorities (mainly African American) were more likely to have a shorter circadian period, delayed phase shifts, and were more likely to be shift workers, which are associated with CVD risk factors. Given racial minorities are disproportionately affected by CVD and CVD risk factors, it is important to further understand circadian health as an intervention target and support more research among racial minorities to understand circadian health in these populations.

Listeria monocytogenes, one of the most important bacterial pathogens transmitted through milk, causes listeriosis in humans and animals. This study aimed to investigate the prevalence of L. monocytogenes in raw milk of healthy sheep and goats in the west of Iran (Lorestan Province) by touchdown PCR (TD-PCR). Listeria spp. were found in milk samples taken from 21 sheep (29.16%) and 3 goats (10.71%) whereas L. monocytogenes was isolated from milk samples taken from 4 sheep (5.55%) and 1 goat (3.75%). The results showed that there was a significant difference between sheep and goats in the prevalence of Listeria spp. in their raw milk ( p < 0.05 ), but no significant difference was observed between them in the prevalence of L. monocytogenes. The study findings suggested that the raw milk of healthy sheep and goats was infected with L. monocytogenes and warned of the risk of human infection with listeriosis following consumption of raw and unpasteurized milk.

Enterocytozoon bieneusi is the most common microsporidia in humans worldwide, in addition to infecting a wide range of animals. However, there is limited information about this pathogen in children in Egypt. Here, we carried out a molecular epidemiological study of E. bieneusi in child care centers in three provinces in Egypt. Altogether, 585 fresh fecal samples were collected from children attending 18 child care centers in El-Dakahlia, El-Gharbia, and Damietta provinces in Northeast Egypt during March 2015 to April 2016. PCR and sequence analyses of the ribosomal internal transcribed spacer (ITS) were used to detect and genotype E. bieneusi. Twenty-seven fecal samples (4.6%, 27/585) were positive for E. bieneusi. Five genotypes were identified, including type IV (n = 13), Peru8 (n = 9), Peru6 (n = 2), Peru11 (n = 2), and D (n = 1). Phylogenetic analysis indicated that the five genotypes of E. bieneusi detected in this study were clustered into zoonotic group 1. These data provide important information on the prevalence and genetic diversity of E. bieneusi in children in this country. Further epidemiological studies should be conducted to elucidate the role of zoonotic transmission in human E. bieneusi infections.

Semen characteristics of Uda sheep and the effects of the egg yolk and coconut milk-based extenders on the quality of semen preserved at 4 oC and -196 oC were evaluated. Semen was collected from six Uda rams using an electro-ejaculator twice a week for ten weeks. Fresh semen samples were pooled and analyzed macroscopically and microscopically. The pooled semen was divided into 2 aliquots. One aliquot was extended in OviPlus® and egg yolk. The second aliquot was extended with OviPlus® and coconut milk. Each of the aliquots was further subdivided into 2 parts and evaluated microscopically. One part was chilled at 4 oC and evaluated for the same parameters after extension at 24, 48 and 72 hours. Second part was loaded into 0.25 ml plastic straws for cryopreservation at -196 ℃ and analyzed after 24 hours. The post thaw spermatozoa motility, livability and morphological abnormalities were determined at 24, 48 and 72 hours. The motility and concentration of freshly collected Uda semen were 81.7 ± 1.7 % and 3.2 ± 0.3 ×109/ml respectively. After extension, the motility decreased significantly (P < 0.05) from 82 % at 3 hours to 17 % at 72. The percentage live spermatozoa of the chilled semen did not differ significantly (P > 0.05) between the two extenders. Post thaw spermatozoa motility and livability were significantly (P < 0.05) reduced. There were significant differences (P < 0.05) between the post-thaw proportions of morphological abnormalities, between semen preserved at 4 oC and the frozen-thawed semen. In conclusion, semen motility, livability, and morphological abnormalities of Uda ram are equally preserved in coconut milk and egg yolk-based extenders at 4 oC up to 24 hours post extension. However, semen motility and livability were significantly reduced in the Uda semen earlier cryopreserved at -196 oC after thawing.

Lactoferrin is a protein, primarily found in milk that has attracted the interest of the food industries due to its health properties. Nevertheless, the instability of lactoferrin has limited its commercial application. Recent studies have focused on encapsulation to enhance the stability of lactoferrin. However, the molecular insights underlying the changes of structural properties of lactoferrin and the interaction with protectants remain poorly understood. Computational approaches have proven useful in understanding the structural properties of molecules and the key binding with other constituents. In this review, comprehensive information on the structure and function of lactoferrin and the binding with various molecules for food purposes are reviewed, with a special emphasis on the use of molecular dynamics simulations. The results demonstrate the application of modeling and simulations to determine key residues of lactoferrin responsible for its stability and interactions with other biomolecular components under various conditions, which are also associated with its functional benefits. These have also been extended into the potential creation of enhanced lactoferrin for commercial purposes. This review provides valuable strategies in designing novel nutraceuticals for food science practitioners and those who have interests in acquiring familiarity with the application of computational modeling for food and health purposes.

Currently, Black men in the United States are greater than 1.5 times as likely to be diagnosed with prostate cancer and more than twice as likely to succumb to the disease. While racial disparities in prostate cancer have been well documented, we must analyze these disparities in the correct context. Discussion of these disparities without correctly describing race as a social construct and acknowledging the impact of structural racism is insufficient. This article reviews the disparities seen in screening, treatment, outcomes, and clinical trial participation. We conclude by outlining future steps to help understand and study disparities, as we strive toward equitable outcomes.

The study was conducted on the Erbil Dairy Herd of the Erbil city, to evaluate the effect of body condition score of Bokani dairy cow on milk composition. Milk samples were examined weekly for milk yield and milk fat, protein percentage, fat / protein ratio, lactose, solids not fat (SNF) and freezing point for sixty days. Body condition score of individual cows was recorded in a 1-5 scale. Milk samples were collected from individual cow. Samples collected from cows having similar body condition score were mixed together to make composite sample. The results revealed that the body condition score was affected milk yield and fat percentage significantly (P

Synbiotics have a positive effect on the composition of the gut microbiota. They will increase the production of short-chain fatty acid that has modulating effect on gastrointestinal epithelial cell integrity, appetite regulation, and immune function. The aim of this study is to determine the effect of synbiotics (L. plantarum Dad-13 and fructo-oligosaccharide) on gut microbiota composition (L. plantarum, Bifidobacterium and Enterobacteriaceae) in stunting children under five in Yogyakarta, Indonesia. The research methods used double blind randomized controlled trials with parallel design. The sample consisted of 39 stunting children under five which was divided into 19 subjects as a synbiotic group given synbiotic (L. plantarum Dad-13 1x1010 CFU and fructo-oligosaccharide 700 mg) powder and 20 subjects as a placebo group given skim milk. The intervention was carried out for 90 days. The result showed that, statistically, there were significant differences in synbiotic group on gut microbiota (increased in L. plantarum and Bifidobacterium, while decreased in Enterobacteriaceae). Protein and carbohydrate were significantly increasing (p=0.000; p=0.001) in synbiotic group compared to placebo group. Body weight and height were significantly different (p=0.000) in both groups. Bodyweight and height of children on synbiotic group was increasing 1.02 and 1.6 times higher than placebo group. Neither morbidity nor weight loss was recorded throughout consumption period. Synbiotic powder has significantly positive effect on gut microbiota that can induce nutrient intake, height and weight gain of stunting children.

Escherichia coli O157:H7 is one of the most important emerging foodborne pathogens and cause life-threatening disease condition in consumers worldwide. A cross-sectional study was carried out from February 2020 to August 2020 in Gojo and Shukute towns, Jeldu district, West Shewa Zone, Oromia region, Ethiopia to isolate and identify E. coli O157:H7 from raw cow’s milk samples and determine antimicrobial susceptibility of the isolates. A total of 262 milk samples (127 from Gojo and 135 from Shukute towns) were collected from dairy cows (126 from udder, 115 from milking bucket) and 21 from collection tanks and examined bacteriologically. The isolates were tested with a series of biochemical tests followed by a latex agglutination test for identification and confirmation of E. coli O157:H7. The antimicrobial susceptibility profile of the isolated E. coli O157:H7 was performed using the Kirby-Bauer disk diffusion method. The study revealed 1.5% (95% Confidence interval [CI]: 0.4–3.8%) of the collected raw milk was contaminated with E. coli O157:H7. The isolates showed 100% susceptibility to azithromycin, norfloxacin, nitrofurantoin, amikacin, chloramphenicol, tetracycline, and trimethoprim-sulfamethoxazole. In contrast, the isolates showed 75% and 100% resistance to ampicillin and cefotaxime, respectively. In conclusion, the consumption of raw milk may constitute a public health hazard due to contamination with E. coli O157:H7. Farmers and farmworkers should be trained on milk hygiene and proper milk handling practices.

This study was carried out to determine the association between milk production characteristics at the start of lactation (the first three month of lactation) and the performance of reproduction within dairy cows of Algeria. Data were collected from Holstein cows (n=920) that calved between October 2017 and October 2019. Reproductive parameters included in the study were: calving to first-service interval (CFSI, days), calving to conception interval (CCI, days), services per conception (SPC), and conception rate at first-service (CRFS %). Milk parameters such as peak milk yield, cumulative milk yield in the first 30 days (Milk30), 60 days (Milk60) and 100 days (Milk100) postpartum of the cows. The milk composition traits analyzed were milk fat concentration (MF %) and milk protein concentration (MP %). These variables were used to calculate fat to protein ratio (FPR) for each stage of lactation (stage 1: 15–30 days, stage 2: 45–60 days and stage 3: 75–90 days postpartum). Pearson’s correlation analysis was used to determine the correlation between reproductive parameters and milk production variables.The obtained results showed that peak milk yield, cumulative milk yield in the first 60 days (Milk60) and 100 days (Milk100) were significantly and positively (P

In the omics era, saliva, a filtrate of blood, may serve as an alternative, noninvasive biospecimen to blood, although its use for specific metabolomic applications has not been fully evaluated. We demonstrated that the saliva metabolome may provide sensitive measures of traffic-related air pollution (TRAP) and associated biological responses via high-resolution, longitudinal metabolomics profiling. We collected 167 pairs of saliva and plasma samples from a cohort of 53 college student participants and measured corresponding indoor and outdoor concentrations of six air pollutants for the dormitories where the students lived. Grand correlation between common metabolic features in saliva and plasma was moderate to high, indicating a relatively consistent association between saliva and blood metabolites across subjects. Although saliva was less associated with TRAP compared to plasma, 25 biological pathways associated with TRAP were detected via saliva and accounted for 69% of those detected via plasma. Given the slightly higher feature reproducibility found in saliva, these findings provide some indication that the saliva metabolome offers a sensitive and practical alternative to blood for characterizing individual biological responses to environmental exposures.

Whey protein has been shown to prevent exercise-induced protein degradation and muscle damage. We hypothesized that whey protein would regulate muscle cell differentiation. Adding various concentrations of whey protein to C2C12 myoblasts induced cell differentiation and MyoD (myogenic differentiation protein) expression as well as the phosphorylation of AKT (protein kinase B). Whey protein-induced differentiation-specific markers increased the enzymatic activities of creatine kinase and citrate synthase and the expression of muscle-specific microRNA. Whey protein elevated AKT phosphorylation on Thr308 and Ser473, which was inhibited by LY294002 (a non-selective phosphoinositide 3-kinases inhibitor), suggesting that whey protein acts via PI3K (phosphatidylinositol 3-kinase). Blocking of the PI3K/AKT pathway with specific inhibitors revealed its requirement in mediating the promotive effects of whey protein on C2C12 cell differentiation. These effects of whey protein on myoblast differentiation suggest its positive influence in preventing muscle atrophy.

The purpose of this study was to determine the ratio of estrogen concentrations given cassava peel feed supplementation. A total of 24 cows of Friesian Holstein, weighing 250-300 kg were divided into two groups and each group contains 12 replications. The first group is Friesian Holstein breeds with the condition that they are given elephant grass feed ad libitum and 25 kg of tofu dregs. The second group is Friesian Holstein breeds with the condition that they are fed ad libitum elephant grass, 25 kg of tofu dregs, and 25 kg of cassava peel. The milk samples were then taken to be tested for estrogen levels using the direct competitive ELISA. Analysis of estrogen concentration data was then carried out by normality test using Shapiro Wilk test then followed by the Paired T-test with a significance level of 5%. Based on the Paired T sample correlation test was 0.072 (p>0.05), which means that the feed gave the cassava peel and not the cassava peel was negatively associated. Based on the Paired T-test is 0.193 (p>0.05), which means there is no significant relationship between the 2 test groups. It can be concluded that there is no significant difference in the estrogen concentration of Friesian Holstein cattle fed with and without cassava peel supplementation.

Background: Ureaplasma urealyticum (U. urealyticum) and Mycoplasma genitalium (M. genitalium) may colonize the male genital tract. However, the negative effects of these bacteria on overall sperm quality, including semen pH, sperm concentration, motility, morphology, and total sperm count remain unclear. Objective: This study aimed to determine the presence of genital U. urealyticum and M. genitalium in semen and evaluate the effect of these organisms on sperm quality. Materials and Methods: A cross-sectional study was conducted on 380 men from infertile couples at a tertiary university hospital from July 2017 to June 2018. Semen quality was analyzed according to the World Health Organization 2010 standard, and U. urealyticum and M. genitalium were detected in the semen samples using polymerase chain reaction. Results: 338 men (88.9%) presented with at least one abnormal semen parameter. The detection rates of U. urealyticum and M. genitalium were 16.05% and 0.79%, respectively. There was no significant difference between the Ureaplasma-positive group and the Ureaplasma-negative group in terms of sperm characteristics. Sperm motility and sperm vitality in the Mycoplasma-positive group were much lower than those in the Mycoplasma-negative group (p = 0.02 and p < 0.001, respectively). Conclusion: The presence of U. urealyticum in the semen of infertile men did not affect the sperm characteristics. Although the positive rate of M. genitalium was low, colonization by these bacteria was more likely to negatively affect sperm quality. Key words: Ureaplasma urealyticum, Mycoplasma genitalium, Infertility, Spermatozoa.

In this study, eight types of boron-based flame retardants were performed to evaluate theeffects of different boron components on the combustibility of the bamboo filaments. Disodium octaborate tetrahydrate, boric acid/borax, and nano-ZnBO4were used as the active flame retardant components. Besides, other inorganic flame retardants including nano-SiO2and ammonium polyphosphate (APP) were also introduced in order to increase the flame retardant of these boron-based components. The combustibility of the bamboo filaments treated with different flame retardants were evaluated by cone calorimeter analysis. Theresults showed that the flame retardants including the heat release and smoke release resistance of the bamboo filaments with different boron-based components and nano-SiO2or APP, could be significantly improved, especially, in the samples treated with the compound flame retardant composed of boric acid, borax and nano-SiO2, which was attributed to the synergistic effect of these flame retardant components.

The beaches of Oran are among the busiest in Algeria. However these beaches are exposed to multiple dangers in particular to pollution which poses serious problems and which can also hinder any proper use of the sea.This paper is an assessment of the physico-chemical and bacteriological quality of some beaches where swimming is allowed along the Oranese coast in Algeria, specifically the Kristel Beach and the beach of Les Andalouses seaside resort. Fecal streptococci are normal hosts of the intestine of humans and warm-blooded animals. Research concerning them associated with that of fecal coliforms is a good indication of fecal contamination. Their presence indicates long term contamination of fecal origin while the presence of fecal coliforms indicates a contamination of recent fecal origin. This is why it may become necessary to proceed to the confirmation stage to detect the presence of E. Coli, which is in fact the real indicator sought in this context, through the necessary use of E. Coli specific culture media.The results obtained show a slight difference between the two sites as the beach of Les Andalouses is a bit more polluted compared to that of Kristel. Still, both beaches remain of good quality with regard to national and international standards.

This study aimed to determine the effect of age on bulls’ productivity and fresh semen characteristics of Simmental bull in Indonesia. A total of 1071 data of semen collection and production from four age groups (two years old (yo), four yo, ≥ 10 yo with high semen rejection (≥10 HR), and ≥ 10 yo with low semen rejection (≥10 LR) were used in this study to evaluate the productivity and characteristics of fresh semen. The results showed that the pre-freezing and post-freezing semen rejection rate of ≥10 HR group was higher (P0.05) than the other groups. The four yo group had the percentage of second semen ejaculation each collection was higher (P0.05) than the other groups. Furthermore, semen volume, sperm concentration, and total sperm concentration significantly increased (P0.05) until four yo and then decreased (P0.05) in ≥ 10 yo groups. The ≥10 HR group had the volume and total sperm concentration significantly different (P0.05) with a group of ≥10 LR. Total sperm motility, individual motility, and mass movement were lower (P0.05) in ≥10 HR than the other groups. In conclusion, age differences of bulls can affect the productivity and characteristics of fresh semen.

This study aims to determine the effect of additional feed with depolarizing katuk leaves on the production and quality of colostrum and colostrum milk in Friesian Holstein dairy cows. There were 21 dairy cows that had just giving birth, divided into 3 groups of 7 each, namely the control group (complete feed), BKD (complete feed added with Depolarizing Katuk Powder), PKD (complete feed added with Depolarizing Katuk Pellet). Depolarizing katuk feed was given 100 grams per head per day as a feed additive. Parameters observed were feed consumption, production and quality of colostrum and colostrum milk. The results showed that there was no difference in the consumption of feed supplemented with depolarizing katuk leaves, colostrum production, milk density, total solid colostrum, Solid non-fat, lactose contents, and protein contents of colostrum and colostrum milk compared to the control group. Significant differences occurred in colostrum milk production, total solid colostrum milk, and fat content of colostrum and colostrum milk. It was concluded that depolarizing katuk leaves could be used as additional feed to increase the production and total solids of colostrum milk, and increase the fat content of colostrum and colostrum milk. Keywords: colostrum, colostrum milk, depolarizing katuk leaf, Friesian Holstein

Donkey milk (DM) has been known in the world for 5000 years for its benefits for human nutrition and health. Nowadays, DM has become more and more attractive as a commercial product. DM contains several physiologically functional components, including high-quality whey proteins, vitamins, important minerals, unsaturated fatty acid and bioactive components. Therefore, it is not only consumed as food but also as a remedy. The average daily milk yield of a female donkey over the entire lactation season was 1.57 ± 1.12 kg/day and fluctuated between 0.20 and 6.00 kg/day. Average milk concentrations (±SD) of fat, protein, lactose, total solids and ash in DM were 0.63 ± 0.41%, 1.71 ± 0.24%, 6.34 ± 0.37%, 9.11 ± 0.95% and 0.39 ± 0.04%, respectively. Interestingly, DM is similar in composition to mare’s milk, and both are similar to mother’s milk. The anatomical and morphological properties of the mammary gland of the female donkey are special and can be compared with those of mare udders. However, the cistern cavity of the mammary gland of female donkeys is characterized by the presence of multiple pockets that open directly into the teat, instead of a single cistern cavity. Therefore, the mammary gland capacity in donkey mare is low and milking technique and routine are of most importance. So far there is no special milking machine for female donkeys and mares. The milking machines used nowadays were initially designed for smaller sheep and goat udders. The company Siliconform, Germany, has set itself the task of developing an optimized milking machine for donkey mares, which is adapted to the anatomical and morphological properties of the donkey mammary gland. Furthermore, it should achieve a physiologically ideal milking process meeting high animal welfare standards for increased milk production with high quality standards.

The article presents the results of a study of combined milk. According to the organoleptic evaluation, combinations of cow's and mare's milk were selected in the ratio of 50:50 and 80:20, according to the revealed physico-chemical indicator, a positive evaluation of the combination of 80:20 was given. When determining the combined milk in a scanning electron microscope, an improvement in the mineral composition was observed. It was found that in the composition of combined milk, the sodium content increased by 7.38%; potassium 3.41%; chlorine 15.12% compared to natural milk.

Olecranon fractures are most frequently stabilized by tension band wiring (TBW), which unfortunately leads to relevant implant removal rates due to K-wire migration and soft tissue irritation. As lag screw osteosynthesis (LSO) might be a gentle and effective alternative in simple fracture patterns, the goal of the present study was to biomechanically compare LSO with TBW in simple olecranon fractures at a cadaver model. A simple olecranon fracture (Mayo type IIA) was created in eight pairs of human cadaver elbows, which were pairwise fixed by either TBW or two transcortical 4.0 mm lag screws. Biomechanical testing was conducted as a pulling force, applied to the triceps tendon in a 90° position. First, cyclic loading between 10 and 300 N was performed for 50,000 cycles. Afterward, maximum load was raised by 0.02 N/cycle until construct failure, what was defined as displacement >2 mm. Besides fracture displacement, failure cycle and failure load, the modes of failure were analyzed. Within the first five cycles, there was no significant difference in displacement (median TBW: 0.2 mm; LSO: 0.5 mm; p = 0.091). Both after 2000 (median TBW: 0.2 mm; LSO: 0.6 mm; p = 0.042) and after 20,000 cycles (median TBW: 0.4 mm; LSO: 0.9 mm; p = 0.027), the difference was significant. Failure cycle (median TBW: 72,639 cycles; LSO: 43,429 cycles; p = 0.017) and failure load (median TBW: 702 N; LSO: 303 N; p = 0.025) differed significantly as well. TBW mostly (6/8) failed at the lock of the cerclage wire, whereas most LSO constructs (5/8) failed as a pullout of the proximal fragment. In conclusion, to our biomechanical findings at human cadaver specimens, simple olecranon fractures treated by LSO show higher dislocation rates and lower failure loads compared to conventional TBW and mostly fail by pullout of the proximal fragment.

This study investigated the effect of different milking systems on the milk composition and microbial community of raw milk in a commercial dairy farm. Raw milk samples from conventional milking system (CMS) and automatic milking system (AMS) were collected and the microbiota on each was assessed by 16S rRNA gene sequencing. Results showed that the acetone (P = 0.031) and β-hydroxybutyrate (P≤0.001) levels in the raw milk of the AMS group were increased compared with the CMS group. Principal component analysis, unweighted and weighted principal coordinates analysis, and heat map of microbial community composition in the raw milk showed a clear separation between two groups. AMS increased the abundance of the genera Acinetobacter (FDR = 0.004) and Staphylococcus (FDR = 0.004) in the raw milk compared with the CMS group. In contrast, the abundance of the genera Pseudomonas (FDR = 0.028), Lactococcus (FDR = 0.015), Sphingobacterium (FDR = 0.004), Brevundimonas (FDR = 0.005), and Chryseobacterium (FDR = 0.042) in the raw milk was reduced in the AMS group compared with the CMS group. The abundance of the genera Acinetobacter and Staphylococcus in the raw milk was positively correlated with the β-hydroxybutyrate, acetone, free fatty acid, citric acid, and urea nitrogen levels. Furthermore, the abundance of the genus Acinetobacter in the raw milk was negatively correlated with the somatic cell counts. The study demonstrates that the introduction of AMS in the dairy farm can regulate microbiota composition in the raw milk and this modification may exert an effect on reducing the somatic cell counts in the raw milk.

Feed is the main factor impacting the composition and quality of milk of dairy animals. Therefore, the present review explores the effects of feed and nutrition on milk fat content and levels of healthy fatty acids (FA) in milk consumed by humans. Milk and dairy products are two main sources of healthy and unhealthy FA in human nutrition. The concentrations of FA in milk depend mainly on diets; therefore, milk FA concentrations and ratios can be greatly altered by some feeding strategies. Dietary supplementation of the diets of dairy livestock with vegetable seeds or oils, microalgae and phytogenic feed additives, and feeding of some grasses can enhance the contents of healthy FA, including n-3 FA, α-linolenic acid, conjugated linoleic acid (CLA) and, generally, unsaturated FA in milk and dairy products. Enrichment of milk with healthy FA may make milk a source of anticarcinogens (CLA and polyphenols) for human health. This review, therefore, focusses on the current research findings on enrichment of milk with healthy FA and summarizes some effective supplementation strategies to alter milk FA profile.

Background: A notable pandemic arisen during the COVID-19 pandemic has developed globally in intensive care units, with patients developing pressure ulcers (PUs) after being ventilated mechanically in the prone position. Objectives: The aim was to identify risk factors independently predictive of the development of PUs in adult patient populations treated with prone positioning and to evaluate a possible epidemiological association between the prevalence of PUs and specific clinical characteristics so as to develop clinical indicators for the prevention of PUs. Finally, the aim was to examine our study participants against the incidence of PUs with respect to the length of their stay. Methods: : This retrospective study enrolled patients hospitalized during the period of May 2020 through January 2021. Data was collected from 299 patients hospitalized and having required prone positioning ventilatory therapy in critical care areas (short-stay units, emergency units, and intensive care units), all of which had developed Pus of at least grade two according to the classification system proposed by the NPUAP/EPUAP. Results: : Patients who had developed PUs had a longer hospitalization stay overall and were more prone to die during hospitalization. Patients who developed Pus were more frequently males, with higher initial levels of CPK and ferritin. Conclusions: The study reveals valuable information on the most important risk factors in the development of PUs due to prone positioning. We have described how the total number of days of hospitalization is significantly related to the development of PUs. Even a PU is not a life-threatening lesion, the implementation of improved positioning protocols may enhance results in critical patient care. We believe that this is a current, globally underestimated problem as the incidence of COVID-19 patients requiring prone positioning—and, therefore, at risk for PUs—is increasing daily.

Following removal of hides and viscera during beef processing, carcasses are inspected for tissue adhesions that can affect meat quality or harbor bacteria. Carcasses with pleural or abdominal adhesions may be diverted from the production line for manual excision and then returned to the line. No published data indicate whether adhesion excision is associated with bacterial contamination. Therefore, our objective was to determine the presence and concentration of generic Escherichia coli and non-E. coli coliforms from the internal and external surfaces of carcasses that were, or were not, diverted for adhesion excision. During 9 processing days over a 4-month period in a large commercial beef processing facility, 1,738 carcass sponge samples from 2,730 cm2 areas on both the internal and the external surfaces of carcasses with and without tissue adhesions were collected. Coliforms and E. coli were cultured and enumerated using Petrifilm procedures, and data were analyzed with mixed models. Coliforms were present at higher concentrations than E. coli, and prevalence and mean log concentrations of both coliforms and E. coli were significantly higher for samples from the external than from the internal surfaces of carcasses. However, differences in prevalence and concentration of coliforms between external and internal surfaces varied significantly based on whether carcasses had adhesions excised. The difference was greatest for coliforms present on the external (2.06 log CFU/100 cm2) versus the internal (0.93 log CFU/100 cm2) carcass surfaces without adhesions, whereas the difference in concentrations from the external (1.80 log CFU/100 cm2) and the internal (1.31 log CFU/100 cm2) surfaces of carcasses with adhesions was not as large. These results indicate that surveillance of carcass bacteria may be affected by whether the external versus the internal surfaces are sampled and whether carcasses are diverted for excision of adhesions.

Purpose: Controversy exists regarding the role preoperative urodynamic study for asymptomatic closed spinal dysraphism as it has failed to reveal the benefit in surgical decision and expectation of urological outcomes. We explore the relationship between preoperative videourodynamic study and postoperative urological outcomes after toilet training completed, focusing on their capability of spontaneous voiding.Methods: We retrospectively reviewed the data of 181 patients who underwent preventive spinal cord untethering and followed at least till the completion of toilet training. Before untethering, patients underwent preoperative videourodynamic study. Postoperative voiding function was evaluated in 3 phases: (1) till postoperative 6 months, (2) till the completion of toilet training, and (3) 2 years after toilet training. Changing distribution of emptying pattern at each period was described. Also, relevance to preoperative urodynamic parameters on spontaneous voiding and urinary continence after toilet training was assessed.Results: Spinal lipoma and low lying conus were found in 145 (80%) and 128 patients (70.7%), respectively. Spontaneous voiding was found in 125 (69.1%), 164 (90.6%), and 162 patients (89.5%) at postoperative 6 months, till the toilet training, and 2 years after toilet training, respectively. Videourodynamics helped to clarify the presence of vesicourethral synergy. This was correlated with spontaneous voiding at postoperative 6 months and better urinary continence after 2 years of toilet training.Conclusions: Eventual spontaneous voiding was achieved till toilet training in 90% patients following preventive untethering. Those showing preoperative vesicourethral synergy was associated with faster achievement of spontaneous voiding and better urinary continence when they enter elementary school.

The toilet training readiness was influenced by various factors, such as the mother’s attitude, role, and the child's readiness. This study aimed to determine the correlation between mothers' attitudes and roles with toilet training readiness in toddlers. This study used a descriptive correlational design using a cross-sectional approach. The research sample was 96 respondents using an accidental sampling technique. The analysis used the chi-square test to identify the correlation between mothers' attitudes and roles with toilet training readiness in toddlers. The results of the study showed the mother's attitudes in the positive category (53.1%), the mother’s roles in the good category (54.2%) and toilet training readiness in the ready category (69.8%). The results of the chi-square test showed a correlation between mother's attitudes with toilet training readiness (p-value
