In conjunction with the investigation of intercellular compartmentation of liver carbohydrate metabolism, a new procedure for isolation of tissue samples from freeze-dried cryosections was developed. It was designed to permit assessment of functional differences between sinusoids of portal and septal origin, and to extend investigation of liver cell heterogeneity along sinusoids to the level of the structural-functional unit. Application of this procedure, together with microchemical assays of high analytical sensitivity, enabled measurement of 50 individual glucose and glucose-6-P values in a single cross-sectional area of about 0.75 mm2 of a liver unit. Preliminary results on the distribution of glucose and glucose-6-P indicated that, in a state of overall glucose release glucose levels were significantly higher in the center than in the periphery of the unit. Overall glucose release by the liver resulted from both release and uptake of glucose along sinusoids. Glucose-6-P was highest in the periphery and decreased toward the center. Microchemical data, furthermore, indicated possible functional heterogeneity of sinusoids, insofar as both glucose and glucose-6-P gradients were steeper in "portal-central" than in "septal-central" sinusoids.

AimThis study’s objective was to assess the risk of severe in-hospital complications of patients admitted for COVID-19 and diabetes mellitus (DM).DesignThis was a cross-sectional study.SettingsWe used pseudonymised medical record data provided by six general hospitals from the HM Hospitales group in Spain.Outcome measuresMultiple logistic regression analyses were used to identify variables associated with mortality and the composite of mortality or invasive mechanical ventilation (IMV) in the overall population, and stratified for the presence or absence of DM. Spline analysis was conducted on the entire population to investigate the relationship between glucose levels at admission and outcomes.ResultsOverall, 1621 individuals without DM and 448 with DM were identified in the database. Patients with DM were on average 5.1 years older than those without. The overall in-hospital mortality was 18.6% (N=301), and was higher among patients with DM than those without (26.3% vs 11.3%; p<0.001). DM was independently associated with death, and death or IMV (OR=2.33, 95% CI: 1.7 to 3.1 and OR=2.11, 95% CI: 1.6 to 2.8, respectively; p<0.001). In subjects with DM, the only variables independently associated with both outcomes were age >65 years, male sex and pre-existing chronic kidney disease. We observed a non-linear relationship between blood glucose levels at admission and risk of in-hospital mortality and death or IMV. The highest probability for each outcome (around 50%) was at random glucose of around 550 mg/dL (30.6 mmol/L), and the risks flattened above this value.ConclusionThe results confirm the high burden associated with DM in patients hospitalised with COVID-19 infection, particularly among men, the elderly and those with impaired kidney function. Moreover, hyperglycaemia on admission was strongly associated with poor outcomes, suggesting that personalised optimisation could help to improve outcome during the hospital stay.

Abstract Low blood glucose levels at the start of farrowing have been associated with increased farrowing duration and stillbirth rate. This study evaluated changes in sow blood glucose (BG) on the day of farrowing and investigated relationships between sow and litter parameters and BG. The study was carried out over 12 h from 0600h (time of last feeding) on the day sows were induced to farrow (d 115 of gestation) as a cross-sectional survey using 42 sows/gilts of which 32 farrowed. Blood samples (1.2 μL) were collected from an ear vein of each sow every 2 h from 0600 h; glucose was measured using a glucometer (Accuchek Aviva; Roche Diabetes Care, Inc., Indianapolis, IN). Sow parameters recorded included parity, body condition score (BCS: 1 = extremely thin to 5 = extremely fat), number of piglets born, total litter birth weight, and farrowing duration. Linear relationships between sow parameters and BG were developed using PROC REG of SAS. Sows that farrowed had similar (P &gt; 0.05) BG to those that did not (84.4 vs. 86.8 mg/dL; SEM 1.76). Regression relationships between sow parameters and BG were generally weak (adjusted R2 ≤ 0.20). There was no effect (P &gt; 0.05) of time after feeding, time after start of farrowing, or time interval between piglet births on BG. Average BG levels increased linearly (P &lt; 0.05) with sow BCS (7.6 mg/dL/BCS; SE 2.63) but decreased linearly (P &lt; 0.05) with sow parity (-2.5 mg/dL/litter; SE 0.96), litter size (-0.8 mg/dL/piglet; SE 0.28), litter weight (-0.06 mg/dL/kg; SE 0.26), and farrowing duration (-1.8 mg/dL/h; SE 0.82). In contrast to previous research, changes in BG from last feed to start of farrowing (which ranged from 0 to 9 h) and relationship with other sow and litter parameters were relatively limited.

Abstract Blood glucose levels in piglets at birth are potentially associated with survival, however, there has been limited research to quantify these and to establish any associations with piglet characteristics. This study, which evaluated the effects of a number of piglet characteristics on blood glucose levels at birth, was conducted as a cross-sectional survey involving 32 litters. Litter was the experimental unit; piglet was a sub-sample of litter. At birth, piglets were weighed and assigned a vitality score [1 = high vitality; 2 = low vitality (limited mobility and/or respiration)]. Piglets were then dried with a cellulose-based desiccant, and blood samples were collected from half of the piglets in each litter with a vitality score of 1 (n = 226) and all piglets with a vitality score of 2 (n = 7). Samples (1.2 μL) were collected from the vena subcutanea abdominis; blood glucose was measured using a glucometer (Accuchek Aviva; Roche Diabetes Care, Inc., Indianapolis, IN). Effects of piglet characteristics and relationships with blood glucose levels were analyzed using PROC MIXED, PROC GLIMMIX, and PROC REG of SAS, as appropriate. There were no effects (P &gt; 0.05) of piglet birth weight or gender on blood glucose levels. Piglets with a vitality score of 2 had higher (P &lt; 0.05) blood glucose levels than those with a score of 1. Blood glucose levels increased linearly (P &lt; 0.05) with birth order (0.8 mg/dL for each piglet increase). In conclusion, blood glucose levels at birth were higher for piglets with low compared to high vitality and for those born later in the birth order. Further research is needed to establish relationships between blood glucose levels in piglets at birth and subsequent survival.

Background: Nephrotic syndrome is a common illness affecting the paediatric age group and 80% of the idiopathic syndrome is steroid sensitive. Multiple relapses make them vulnerable to the adverse effects of corticosteroids. There is limited literature evidence for the adverse effects of steroids in children with renal pathology.Methods: This descriptive, cross sectional study analyses the adverse effects of oral prednisolone in children and adults with nephrotic syndrome Fifty-five patients with nephrotic syndrome, attending nephrology or paediatric OP, more than 3 years of age and who were on oral prednisolone for a minimum of eight weeks were included in the study. Demographic details, detailed history, lab investigations and ophthalmic examination were done and the results were analysed.Results: Hypertension and behavioural changes were the most common adverse effects followed by dermatological, endocrine and metabolic changes. Infections and gastrointestinal disturbances were more in adults (p <0.05). Short stature was more in children (p< 0.05). There was no abnormality in blood glucose levels and body weight. Hypertension, cushingoid habitus, infections and short stature were statistically less in patients on alternate day prednisolone. But no statistical association could be made between the occurrence of cataract and the pattern of prednisolone use.Conclusions: Adverse effects pattern is different among adults and children. Also, the adverse effects are less with alternate day prednisolone regimen. Long term follow up into their adulthood is needed to analyse the morbidity produced by corticosteroids in these subsets of population.

Health status and micronutrient intake among vegetarian and non-vegetarian in BaliBackground: Several studies have reported that vegetarian diets have health benefits for those adopting the diets.Objective: This study aimed to compare anemia status and micronutrient intake between vegetarians and non-vegetarians in Bali.Methods: This cross-sectional study was conducted in Bali. A total of 240 samples consisting of 160 vegetarians and 80 non-vegetarians were randomly selected. Hemoglobin (Hb) and fasting blood sugar levels were measured using the cyanmethemoglobin method and enzymatic colorimetric, respectively. Meanwhile, the data on micronutrient intakes were collected by interviews using the semi-quantitative food frequency questionnaire (SQFFQ). The data were analyzed using descriptive statistics, and the Mann-Whitney test was performed to analyze the differences.Results: The study’s results showed that the mean Hb levels in the vegetarian group were significantly lower than non-vegetarians (p=0.002; p<0.05), and the anemia status in vegetarian women were higher (22.5%) than non-vegetarian women (2.5%). The mean fasting blood glucose level in non-vegetarians was significantly higher than in the vegetarian group (p=0.000; p<0.05). There were no differences in zinc (Zn) intake between vegetarians and non-vegetarians, but there were significant differences (p<0.05) in vitamin C, vitamin D, vitamin B12, folic acid, magnesium (Mg), calcium (Ca), and iron (Fe) intakes.Conclusions: There were differences in anemia status and fasting blood glucose levels between vegetarians and non-vegetarians. The fasting blood glucose levels of non-vegetarians were higher than vegetarians, and there were differences in the intake of certain micronutrients between vegetarians and non-vegetarians.

Abstract Background: Reproduction is a basic prerequisite to efficient livestock production. Reproductive performance depends upon the normal structure and function of genital organs. Methods: A cross-sectional study was conducted from November 2016 to May 2017 to identify and compare the frequency of pathological lesions in the reproductive tract and to isolate bacteria associated to uterine lesions in female dromedary camels and cows slaughtered at Akaki camel slaughter house and Addis Ababa and Adama municipal abattoirs. Abattoirs were visited once per week for 28 weeks during which three to seven animals on average were slaughtered per day. A purposive sampling technique was employed to examine reproductive tracts of all slaughtered animals (280; 140 cows and 140 camels). Following gross inspection at abattoirs, tissue samples with lesion were collected for histopathological and bacteriological investigation. Result: Various pathological lesions with different degrees of severity were observed in 48 (34.2%) and 51 (36.4%) of dromedary camels and cows, respectively. Uterine lesions were the most prevalent 21.4% lesions observed in dromedary camels followed by ovarian lesions 7.14%; while in cows, ovarian lesions were the major prevalent 16.4% lesions followed by uterine lesion 14.2%. The result showed that there were 56 bacteria isolated from cows uterine lesion with Staphylococcus species 28.5%, Streptococci species 19.6%, Coynebacterium species 8.9%, Escherichia coli 26.78%, Salmonella species 10.7% and Klebsiella species 5.35% being the prominent isolates; while in camels, there were 45 bacteria isolated with Escherichia coli 35.5%, Staphylococcus species 26.6%, Streptococcus species 13.3%, Pseudomonas species 6.6 %, Proteus species 4.4%, Salmonella species 8.8% and Klebsiella species 4.4% being the most frequently isolated. The result showed that the major isolates were similar with slightly higher in cows. Histopathologically, endometrial glands degeneration, sloughing of epithelium, peri-glandular cuffing and infiltrations of inflammatory cell were some of characteristic changes observed in uterus. Conclusions: Pathological lesions in reproductive organs in female dromedary camels and cows showed great prevalence, with similarity in bacterial isolates between the two species. The role of each reproductive lesions and bacterial isolates incriminated as causes of reproductive failures in this livestock species needs further investigation.
