In order to study the fat-soluble vitamin concentration of patients with chronic alcohol-induced pancreatitis (CAIP) we measured vitamins A and E, total lipids, and retinol-binding protein (RBP) in the plasma of 44 patients with CAIP and 83 controls (44 healthy controls; 39 Crohn's disease patients). Mean plasma vitamin E and vitamin E/total lipid ratio were significantly lower in CAIP when compared with either control or Crohn's disease groups. A low vitamin E/total lipid ratio was found in 75% of CAIP patients (91% with steatorrhea) and a ratio less than 1.0 was virtually 100% predictive of steatorrhea. The mean plasma vitamin A level for the CAIP group was significantly lower (overall 16%, 38% with steatorrhea) than in controls. Patients with CAIP show subnormal plasma levels vitamin E more often as compared to vitamin A. Further, the plasma vitamin E/total lipids ratio may be a sensitive and practical means in the detection and follow-up of steatorrhea in these patients.

Retinopathy with Vitamin E Deficiency (RVED) is a familial disease in the English Cocker Spaniel (ECS) dog breed. Ophthalmic abnormalities observed in RVED-affected ECS include lipofuscin granule deposition within the tapetal fundus and subsequent retinal degeneration resulting in visual deficits. Affected dogs may also exhibit neurological signs that include ataxia and hindlimb proprioceptive deficit.

Objective: To evaluate the effects of a combination of carnitines, L-arginine, L-cysteine and myo-inositol on metabolic and reproductive parameters in PCOS overweight/obese patients.
Methods: This was a retrospective study analyzing information of a group of PCOS ( = 25) overweight/obesity patients, not requiring hormonal treatment, selected from the database of the ambulatory clinic of the Gynecological Endocrinology Center at the University of Modena and Reggio Emilia, Modena, Italy. The hormonal profile, routine exams and insulin and C-peptide response to oral glucose tolerance test (OGTT) were evaluated before and after 12 weeks of a daily oral complementary treatment with L-carnitine (500 mg), acetyl-L-carnitine (250 mg), L-arginine (500 mg), L-cysteine (100 mg) and myo-inositol (1 gr).
Don't Sleep on Vitamin D: Vitamin D is Associated with Sleep Variability in Apparently Healthy Adults.

Vitamin D is associated with sleep quality and duration, but it's unclear whether vitamin D status influences sleep variability. Therefore, we sought to determine whether vitamin D status was associated with sleep variability in healthy adults. We assessed objective sleep, including timing and duration standard deviation () using the Philips Actiwatch Spectrum and subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) in 130 adults.

Roughly 90% of the Polish population experiences vitamin D deficiency. The 3-epi-25(OH)D2 and 3-epi-25(OH)D3 are stereoisomers of 25(OH)D2 and 25(OH)D3, and they can inadvertently be included in measurements of 25(OH)D levels, potentially leading to its overestimating. We aimed to measure 25(OH)D2 and 25(OH)D3, their epimers 3-epi-25(OH)D2 and 3-epi-25(OH)D3, and biologically active 1,25(OH)2D3 in patients with cardiovascular disease and healthy volunteers.

Introduction: Chinese herbal medicines are relatively inexpensive and have fewer side effects, making them an effective option for improving health and treating diseases. As a result, they have gained more attention in recent years. The weaning period is a critical stage in the life of yaks, often inducing stress in calves.
