PHENOTYPIC RELATIONSHIP BETWEEN LINEAR TYPE TRAITS AND LONGEVITY OF SIMMENTAL COWS

U istraživanju fenotipske povezanosti između svojstava vanjštine i dugovječnosti korišteni su podaci Hrvatskog stočarskog centra o 4710 krava simentalske pasmine. Krave su izlučene u razdoblju između 1998. i 2007. godine te su imale podatke o ocjenama vanjštine. Dugovječnost je promatrana kroz dužinu proizvodnog vijeka koja je definirana kao broj dana od prvog telenja do datuma izlučenja. Grla su u proizvodnji bila prosječno 44,7 mjeseci odnosno 3,2 laktacije, dok je životni vijek iznosio u prosjeku 70,4 mjeseci. Između svojstava okvira i dugovječnosti simentalskih krava koeficijenti korelacije su se kretali u rasponu od 0,03 do 0,18, gdje je najniža statistički značajna (P<0,05) korelacija utvrđena između položaja zdjelice i dugovječnosti. Najviše je sa dugovječnošću bila povezana širina zdjelice (r=0,18, P<0,01). Vrlo niski koeficijenti korelacije utvrđeni su između svojstava vimena i dugovječnosti, a kretali su se u rasponu od 0,02 do 0,06. Pri tom su statistički visoko značajne (P<0,01) korelacije utvrđene između dugovječnosti i središnjeg suspenzornog ligamenta (0,05), dubine vimena (0,06) i debljine sisa (0,06). U odnosu na svojstva okvira i svojstva vimena, svojstva nogu bila su u slabijoj povezanosti sa dugovječnošću. Najjača i statistički visoko značajna (P<0,01) pozitivna korelacija s dugovječnošću utvrđena je za kut skočnog zgloba (0,05) te visinu papaka (0,08), dok su negativne i nesignifikantne korelacije utvrđene između dugovječnosti i izraženosti skočnog zgloba (-0,02) te putica (-0,01).The data of 4710 Simmental cows from the database of Croatian Livestock Centre were used for calculating the phenotypic correlations between linear type traits and longevity. Cows included in this research were culled from year 1998 to year 2007 and had scores for linear type traits. Longevity was defined as the number of days from first calving until culling. Average length of productive life was 44.7 months that is 3.2 lactations, and average length of true life was 70.4 months. Correlation coefficients between trunk conformation traits and longevity were in range of 0.03 to 0.18. The lowest correlation (P<0.05) was determined between rump side view and longevity, and the highest (P<0.01) between rump width and longevity. Very low correlation coefficients were determined between udder traits and longevity which were in range of 0.02 to 0.06. Statistically significant (P<0.01) correlations were obtained between longevity and suspensory ligament (0.05), udder depth (0.06) and teats thickness (0.06). By comparison with trunk conformation and udder traits, legs traits were in general in lower correlations with longevity. The highest statistically significant (P<0.01) positive correlations were determined between longevity and rear legs side view (0.05) that is longevity and heel depth (0.08). Negative and insignificant correlations were obtained between longevity and hock joint thickness (-0.02), i.e. between longevity and foot angle (-0.01)

Total Synthesis and Functional Evaluation of IORs, Sulfonolipid‐based Inhibitors of Cell Differentiation in Salpingoeca rosetta

The choanoflagellate Salpingoeca rosetta is an important model system to study the evolution of multicellularity. In this study we developed a new, modular, and scalable synthesis of sulfonolipid IOR‐1A (six steps, 27 % overall yield), which acts as bacterial inhibitor of rosette formation in S. rosetta . The synthesis features a decarboxylative cross‐coupling reaction of a sulfonic acid‐containing tartaric acid derivative with alkyl zinc reagents. Synthesis of 15 modified IOR‐1A derivatives, including fluorescent and photoaffinity‐based probes, allowed quantification of IOR‐1A, localization studies within S. rosetta cells, and evaluation of structure‐activity relations. In a proof of concept study, an inhibitory bifunctional probe was employed in proteomic profiling studies, which allowed to deduce binding partners in bacteria and S. rosetta . These results showcase the power of synthetic chemistry to decipher the biochemical basis of cell differentiation processes within S. rosetta

Effects of Neonatal Nutrition Interventions on Neonatal Mortality and Child Health and Development Outcomes: A Systematic Review

Background The last two decades have seen a significant decrease in mortality for children \u3c 5 years of age in low and middle‐income countries (LMICs); however, neonatal (age, 0–28 days) mortality has not decreased at the same rate. We assessed three neonatal nutritional interventions that have the potential of reducing morbidity and mortality during infancy in LMICs. Objectives To determine the efficacy and effectiveness of synthetic vitamin A, dextrose oral gel, and probiotic supplementation during the neonatal period. Search Methods We conducted electronic searches for relevant studies on the following databases: PubMed, CINAHL, LILACS, SCOPUS, and CENTRAL, Cochrane Central Register for Controlled Trials, up to November 27, 2019. Selection Criteria We aimed to include randomized and quasi‐experimental studies. The target population was neonates in LMICs. The interventions included synthetic vitamin A supplementation, oral dextrose gel supplementation, and probiotic supplementation during the neonatal period. We included studies from the community and hospital settings irrespective of the gestational age or birth weight of the neonate. Data Collection and Analysis Two authors screened the titles and extracted the data from selected studies. The risk of bias (ROB) in the included studies was assessed according to the Cochrane Handbook of Systematic Reviews. The primary outcome was all‐cause mortality. The secondary outcomes were neonatal sepsis, necrotizing enterocolitis (NEC), prevention and treatment of neonatal hypoglycaemia, adverse events, and neurodevelopmental outcomes. Data were meta‐analyzed by random effect models to obtain relative risk (RR) and 95% confidence interval (CI) for dichotomous outcomes and mean difference with 95% CI for continuous outcomes. The overall rating of evidence was determined by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Main Results Sixteen randomized studies (total participants 169,366) assessed the effect of vitamin A supplementation during the neonatal period. All studies were conducted in low‐ and middle‐income (LMIC) countries. Thirteen studies were conducted in the community setting and three studies were conducted in the hospital setting, specifically in neonatal intensive care units. Studies were conducted in 10 different countries including India (four studies), Guinea‐Bissau (three studies), Bangladesh (two studies), and one study each in China, Ghana, Indonesia, Nepal, Pakistan, Tanzania, and Zimbabwe. The overall ROB was low in most of the included studies for neonatal vitamin A supplementation. The pooled results from the community based randomized studies showed that there was no significant difference in all‐cause mortality in the vitamin A (intervention) group compared to controls at 1 month (RR, 0.99; 95% CI, 0.90–1.08; six studies with 126,548 participants, statistical heterogeneity I2 0%, funnel plot symmetrical, grade rating high), 6 months (RR, 0.98; 95% CI, 0.89–1.07; 12 studies with 154,940 participants, statistical heterogeneity I2 43%, funnel plot symmetrical, GRADE quality high) and 12 months of age (RR, 1.04; 95% CI, 0.94–1.14; eight studies with 118,376 participants, statistical heterogeneity I2 46%, funnel plot symmetrical, GRADE quality high). Neonatal vitamin A supplementation increased the incidence of bulging fontanelle by 53% compared to control (RR, 1.53; 95% CI, 1.12–2.09; six studies with 100,256 participants, statistical heterogeneity I2 65%, funnel plot symmetrical, GRADE quality high). We did not identify any experimental study that addressed the use of dextrose gel for the prevention and/or treatment of neonatal hypoglycaemia in LMIC. Thirty‐three studies assessed the effect of probiotic supplementation during the neonatal period (total participants 11,595; probiotics: 5854 and controls: 5741). All of the included studies were conducted in LMIC and were randomized. Most of the studies were done in the hospital setting and included participants who were preterm (born \u3c 37 weeks gestation) and/or low birth weight (\u3c 2500 g birth weight). Studies were conducted in 13 different countries with 10 studies conducted in India, six studies in Turkey, three studies each in China and Iran, two each in Mexico and South Africa, and one each in Bangladesh, Brazil, Colombia, Indonesia, Nepal, Pakistan, and Thailand. Three studies were at high ROB due to lack of appropriate randomization sequence or allocation concealment. Combined data from 25 studies showed that probiotic supplementation reduced all‐cause mortality by 20% compared to controls (RR, 0.80; 95% CI, 0.66–0.96; total number of participants 10,998, number needed to treat 100, statistical heterogeneity I2 0%, funnel plot symmetrical, GRADE quality high). Twenty‐nine studies reported the effect of probiotics on the incidence of NEC, and the combined results showed a relative reduction of 54% in the intervention group compared to controls (RR, 0.46; 95% CI, 0.35–0.59; total number of participants 5574, number needed to treat 17, statistical heterogeneity I2 24%, funnel plot symmetrical, GRADE quality high). Twenty‐one studies assessed the effect of probiotic supplementation during the neonatal period on neonatal sepsis, and the combined results showed a relative reduction of 22% in the intervention group compared to controls (RR, 0.78; 95% CI, 0.70–0.86; total number of participants 9105, number needed to treat 14, statistical heterogeneity I2 23%, funnel plot symmetrical, GRADE quality high). Authors\u27 Conclusions Vitamin A supplementation during the neonatal period does not reduce all‐cause neonatal or infant mortality in LMICs in the community setting. However, neonatal vitamin A supplementation increases the risk of Bulging Fontanelle. No experimental or quasi‐experimental studies were available from LMICs to assess the effect of dextrose gel supplementation for the prevention or treatment of neonatal hypoglycaemia. Probiotic supplementation during the neonatal period seems to reduce all‐cause mortality, NEC, and sepsis in babies born with low birth weight and/or preterm in the hospital setting. There was clinical heterogeneity in the use of probiotics, and we could not recommend any single strain of probiotics for wider use based on these results. There was a lack of studies on probiotic supplementation in the community setting. More research is needed to assess the effect of probiotics administered to neonates in‐home/community setting in LMICs

Patients with Crohn's disease have longer post-operative in-hospital stay than patients with colon cancer but no difference in complications' rate

BACKGROUNDRight hemicolectomy or ileocecal resection are used to treat benign conditions like Crohn's disease (CD) and malignant ones like colon cancer (CC).AIMTo investigate differences in pre- and peri-operative factors and their impact on post-operative outcome in patients with CC and CD.METHODSThis is a sub-group analysis of the European Society of Coloproctology's prospective, multi-centre snapshot audit. Adult patients with CC and CD undergoing right hemicolectomy or ileocecal resection were included. Primary outcome measure was 30-d post-operative complications. Secondary outcome measures were post-operative length of stay (LOS) at and readmission.RESULTSThree hundred and seventy-five patients with CD and 2,515 patients with CC were included. Patients with CD were younger (median = 37 years for CD and 71 years for CC (P &lt; 0.01), had lower American Society of Anesthesiology score (ASA) grade (P &lt; 0.01) and less comorbidity (P &lt; 0.01), but were more likely to be current smokers (P &lt; 0.01). Patients with CD were more frequently operated on by colorectal surgeons (P &lt; 0.01) and frequently underwent ileocecal resection (P &lt; 0.01) with higher rate of de-functioning/primary stoma construction (P &lt; 0.01). Thirty-day post-operative mortality occurred exclusively in the CC group (66/2515, 2.3%). In multivariate analyses, the risk of post-operative complications was similar in the two groups (OR 0.80, 95%CI: 0.54-1.17; P = 0.25). Patients with CD had a significantly longer LOS (Geometric mean 0.87, 95%CI: 0.79-0.95; P &lt; 0.01). There was no difference in re-admission rates. The audit did not collect data on post-operative enhanced recovery protocols that are implemented in the different participating centers.CONCLUSIONPatients with CD were younger, with lower ASA grade, less comorbidity, operated on by experienced surgeons and underwent less radical resection but had a longer LOS than patients with CC although complication's rate was not different between the two groups

Exploring Muslim Attitudes Towards Corporate Social Responsibility: Are Saudi Business Students Different?

This study investigates potential differences in attitudes towards corporate social responsibility (CSR) between Saudis and Muslims from other predominately Islamic countries. We propose that Saudi Arabia’s unique rentier-state welfare and higher education systems account for these distinctions. In evaluating our propositions, we replicate Brammer et al. (J Bus Eth 71(3):229–243, 2007) survey on attitudes towards CSR using a sample of Saudi undergraduate and graduate business students and compare the results against data from subjects in other majority Muslim countries. In addition, this work examines possible differences within the Saudi sample with respect to sex and academic level. Our results indicate that our Saudi subjects maintain higher expectations for corporations’ social responsibility within their supply chain than the Brammer et al.’s sample. In contrast, Muslims in the Brammer et al.’s sample hold higher expectations for corporations in supporting societal development and poverty alleviation in comparison to the Saudi sample. We also find within the Saudi sample that females and subjects at higher academic levels are more inclined to hold corporations responsible for social issues related to CSR than males and subjects in lower academic levels. We examine these findings, explore their implications, and propose areas for future research
