Laying hens were fed diets containing 0, 2.5, 5, 10, 15 and 20% whole or ground cottonseed. Birds fed the 15 and 20% ground cottonseed diets rapidly reduced voluntary feed intake and, as a result, suffered a loss in both body weight and egg production. The severity of the dietary effects of cottonseed on productivity and mottled yolks was positively correlated with the level of cottonseed and gossypol in the diet. Egg yolk discoloration was assessed both visually on fresh yolks and using a time exposure to ammonia fumes. Discoloration was easier to detect using the ammonia test. In all cases, egg yolk discoloration was no longer apparent after a maximum of 42 d of feeding a commercial diet.

The goal of diabetes treatment is primarily to save life and alleviate symptoms and secondary to prevent long-term diabetic complications resulting from hyperglycemia. Thus, our present investigation was designed to evaluate the hepato-renal protective effects of gallic acid and p-coumaric acid in nicotinamide/streptozotocin (NA/STZ)-induced diabetic rats. Experimental type 2 diabetes was induced by a single intraperitoneal (i.p.) injection of STZ (65 mg/kg b.wt.), after 15 min of i.p. injection of NA (120 mg/kg b.wt.). Gallic acid and p-coumaric acid were orally administered to diabetic rats at a dose of 20, 40 mg/kg b.wt./day, respectively, for 6 weeks. Body weight, serum glucose, protein profile, liver function enzymes and kidney function indicators was assayed. Treatment with either gallic acid or p-coumaric acid significantly ameliorated the elevated levels of glucose, alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea and uric acid. Both compounds were also found to restore total protein, albumin, and globulin as well as body weight of diabetic rats to near normal values. It can conclude that both gallic acid and p-coumaric acid have potent hypoglycemic and hepato-renal protective effects in diabetic rats. Therefore, our results suggest promising hypoglycemic agents that can attenuate the progression of diabetic hepatopathy and nephropathy.

IntroductionThe PIONEER 7 trial demonstrated superior glycemic control and weight loss with once-daily oral semaglutide with flexible dose adjustment versus sitagliptin 100 mg in type 2 diabetes. This 52-week extension evaluated long-term oral semaglutide treatment and switching from sitagliptin to oral semaglutide.Research design and methodsA 52-week, open-label extension commenced after the 52-week main phase. Patients on oral semaglutide in the main phase continued treatment (n=184; durability part); those on sitagliptin were rerandomized to continued sitagliptin (n=98) or oral semaglutide (n=100; initiated at 3 mg) (switch part). Oral semaglutide was dose-adjusted (3, 7, or 14 mg) every 8 weeks based on glycated hemoglobin (HbA1c) (target <7.0% (<53 mmol/mol)) and tolerability. Secondary endpoints (no primary) included changes in HbA1c and body weight.ResultsIn the durability part, mean (SD) changes in HbA1c and body weight from week 0 were –1.5% (0.8) and –1.3% (1.0) and –2.8 kg (3.8) and –3.7 kg (5.2) at weeks 52 and 104, respectively. In the switch part, mean changes in HbA1c from week 52 to week 104 were –0.2% for oral semaglutide and 0.1% for sitagliptin (difference –0.3% (95% CI –0.6 to 0.0); p=0.0791 (superiority not confirmed)). More patients achieved HbA1c <7.0% with oral semaglutide (52.6%) than sitagliptin (28.6%; p=0.0011) and fewer received rescue medication (9% vs 23.5%). Respective mean changes in body weight were –2.4 kg and –0.9 kg (difference –1.5 kg (95% CI –2.8 to –0.1); p=0.0321). Gastrointestinal adverse events were the most commonly reported with oral semaglutide.ConclusionsLong-term oral semaglutide with flexible dose adjustment maintained HbA1c reductions, with additional body weight reductions, and was well tolerated. Switching from sitagliptin to flexibly dosed oral semaglutide maintained HbA1c reductions, helped more patients achieve HbA1c targets with less use of additional glucose-lowering medication, and offers the potential for additional reductions in body weight.Trial registration numberNCT02849080.

Abstract Background Cannabis use in pregnancy leads to fetal growth restriction (FGR), but the long-term effects on cardiac function in the offspring are unknown, despite the fact that fetal growth deficits are associated with an increased risk of developing postnatal cardiovascular disease. We hypothesize that maternal exposure to Δ9-tetrahydrocannabinol (Δ9-THC) during pregnancy will impair fetal development, leading to cardiac dysfunction in the offspring. Methods Pregnant Wistar rats were randomly selected and administered 3 mg/kg of Δ9-THC or saline as a vehicle daily via intraperitoneal injection from gestational days 6 to 22, followed by echocardiogram analysis of cardiac function on offspring at postnatal days 1 and 21. Heart tissue was harvested from the offspring at 3 weeks for molecular analysis of cardiac remodelling. Results Exposure to Δ9-THC during pregnancy led to FGR with a significant decrease in heart-to-body weight ratios at birth. By 3 weeks, pups exhibited catch-up growth associated with significantly greater left ventricle anterior wall thickness with a decrease in cardiac output. Moreover, these Δ9-THC-exposed offsprings exhibited increased expression of collagen I and III, decreased matrix metallopeptidase-2 expression, and increased inactivation of glycogen synthase kinase-3β, all associated with cardiac remodelling. Conclusions Collectively, these data suggest that Δ9-THC-exposed FGR offspring undergo postnatal catch-up growth concomitant with cardiac remodelling and impaired cardiac function early in life. Impact To date, the long-term effects of perinatal Δ9-THC (the main psychoactive component) exposure on the cardiac function in the offspring remain unknown. We demonstrated, for the first time, that exposure to Δ9-THC alone during rat pregnancy results in significantly smaller hearts relative to body weight. These Δ9-THC-exposed offsprings exhibited postnatal catch-up growth concomitant with cardiac remodelling and impaired cardiac function. Given the increased popularity of cannabis use in pregnancy along with rising Δ9-THC concentrations, this study, for the first time, identifies the risk of perinatal Δ9-THC exposure on early postnatal cardiovascular health.

The Impact

It has been acknowledged that excess body weight increases the risk of colorectal cancer (CRC); however, there is little evidence on the impact of body mass index (BMI) on CRC patients’ long-term oncologic results in Asian populations. We studied the influence of BMI on overall survival (OS), disease-free survival (DFS), and CRC-specific survival rates in CRC patients from the administrative claims datasets of Taiwan using the Kaplan–Meier survival curves and the log-rank test to estimate the statistical differences among BMI groups. Underweight patients (<18.50 kg/m2) presented higher mortality (56.40%) and recurrence (5.34%) rates. Besides this, they had worse OS (aHR:1.61; 95% CI: 1.53–1.70; p-value: < 0.0001) and CRC-specific survival (aHR:1.52; 95% CI: 1.43–1.62; p-value: < 0.0001) rates compared with those of normal weight patients (18.50–24.99 kg/m2). On the contrary, CRC patients belonging to the overweight (25.00–29.99 kg/m2), class I obesity (30.00–34.99 kg/m2), and class II obesity (≥35.00 kg/m2) categories had better OS, DFS, and CRC-specific survival rates in the analysis than the patients in the normal weight category. Overweight patients consistently had the lowest mortality rate after a CRC diagnosis. The associations with being underweight may reflect a reverse causation. CRC patients should maintain a long-term healthy body weight.

Abstract Background Superior mesenteric artery (SMA) syndrome is a well-known but relatively rare complication of anorexia nervosa. Although several reports have proposed surgery for SMA syndrome associated with anorexia nervosa, these have shown poor outcomes or did not reveal the long-term weight course. Thus, the long-term effectiveness of surgery for SMA syndrome in such cases remains unclear. This case report describes a patient with anorexia nervosa who underwent surgery for SMA syndrome. Case presentation An 18-year-old woman presented with anorexia nervosa when she was 16 years old. She also presented with SMA syndrome, which seemed to be caused by weight loss due to the eating disorder. Nutrition therapy initially improved her body weight, but she ceased treatment. She reported that symptoms related to SMA syndrome had led to her weight loss and desired to undergo surgery. Laparoscopic duodenojejunostomy was performed, but her body weight did not improve after the surgery. The patient eventually received conservative nutritional treatment along with psychological approaches, which led to an improvement in her body weight. Conclusions The case implies that surgery for SMA syndrome in patients with anorexia nervosa is ineffective for long-term weight recovery and that conservative treatment can sufficiently improve body weight; this is consistent with the lack of evidence on the topic and reports on potential complications of surgery. Due to difficulties in assessing psychological status, consultation with specialists on eating disorders is necessary for treating patients with severely low body weight.

Background: Alcohol abuse is a systemic disorder. The deleterious health effects of alcohol consumption may result in irreversible organ damage. By contrast, there currently is little evidence for the toxicity of chronic alcohol use on lung tissue. Hence, in this study we investigated long-term effects of ethanol in the lung.Results: Though body weight of rats increased significantly with duration of exposure compared to its initial weight, there was no significant change in relative weight (g/100 g body weight) of lung due to ethanol exposure. The levels of thiobarbituric acid reactive substances (TBARS), nitrite, protein carbonyl, oxidized glutathione (GSS G), redox ratio (GSS G/ GSH ) and GST activity elevated; while reduced glutathione (GSH ) level and activities of glutathione reductase (GR), glutathione peroxidase (GPx), catalase, superoxide dismutase (SOD) and Na+K+ATPase reduced significantly with duration of ethanol exposure in the lung homogenate compared to the control group. Total matrix metalloproteinase activity elevated in the lung homogenate with time of ethanol consumption. Histopathologic examination also demonstrated that severity of lung injury enhanced with duration of ethanol exposure.Methods: 16–18 week-old male albino Wistar strain rats weighing 200–220 g were fed with ethanol (1.6 g/kg body weight/day) up to 36 weeks. At the end of the experimental period, blood samples were collected from reteroorbital plexus to determine blood alcohol concentration and the animals were sacrificed. Various oxidative stress-related biochemical parameters, total matrix metalloproteinase activity and histopathologic examinations of the lung tissues were performed.Conclusions: Results of this study indicate that long-term ethanol administration aggravates systemic and local oxidative stress, which may be associated with lung tissue injury.

It is difficult to objectively assess the chronic effects of housing systems on livestock and particularly on laying hens. However, this seems to be important in the context of animal welfare. Therefore, we conducted the present study in order to compare the effect of two different housing conditions, single cage (SC) and floor pen (FP), on the morphology of the adrenal gland. A higher amount of interrenal cells, which secrete stress hormones, can lead to a difference in the relation of adrenal and interrenal cells, which could be interpreted as an indication of chronic stress. For this purpose, adrenal glands were extracted, prepared, stained and examined by microscopy, and total area of the cut, total area of interrenal cells and total area of adrenal cells were measured. As a result, all laying hens had a higher percentage of interrenal cells than adrenal cells (FP: interrenal cells/adrenal cells = 78.37%/21.63%; SC: 80.00%/20.00%). The median of adrenal–interrenal ratio did not differ significantly (FP = 0.2503, SC = 0.2499), while the variation of the ratio between laying hens in FP and SC showed a slight tendency of a higher ratio in adrenal glands of FP (p < 0.0870). Body weight and adrenal–interrenal ratio were significantly negatively correlated in laying hens in FP (rS = −0.943, p < 0.0048) but not in SC (rS = −0.162, p = 0.7283). There was no significant correlation between body weight and total cell area for interrenal cells or adrenal cells. Body weight was significantly lower for laying hens kept in SC than for laying hens kept in FP (p < 0.0001). Due to the present results, it can be concluded that keeping laying hens in single cages can have a negative effect on body weight.
