Chemical, physical, microbiological and quality attributes studies on River Nile crayfish
In Egypt, red crayfish has become an important new food source, a cheap and popular source of aquatic food, replacing the expensive marine crustaceans. Chemical, physical, microbiological and quality attributes of red crayfish samples were determined. Results show that total weight of inedible parts was 84.64% of the live weight. Value of raw fresh crayfish yield was higher than that boiled. Cooking loss tail meat for boiled crayfish was 33.88% of meat. Moisture, protein and ash contents of raw fresh red crayfish (%) were slightly higher than those of boiled, while fat, fiber and carbohydrates contents (%) were higher than those of raw fresh. Crayfish is considered as a good source for minerals. Amino acids content for raw fresh crayfish was relatively high and the reverse was recorded for boiled crayfish. In conclusion, the boiled red crayfish had better quality attributes than that of raw fresh.Keywords: Red swamp crayfish, chemical composition, physical properties, microbiological aspects and quality attribute
Vitamin D supplementation as an adjuvant therapy for patients with T2DM : an 18-month prospective interventional study
Background
Vitamin D deficiency has been associated with impaired human insulin action, suggesting a role in the pathogenesis of diabetes mellitus type 2 (T2DM). In this prospective interventional study we investigated the effects of vitamin D3 supplementation on the metabolic profiles of Saudi T2DM subjects pre- and post-vitamin D supplementation over an 18-month period.
Methods
T2DM Saudi subjects (men, N = 34: Age: 56.6 ± 8.7 yr, BMI, 29.1 ± 3.3 kg/m2; women, N = 58: Age: 51.2 ± 10.6 yr, BMI 34.3 ± 4.9 kg/m2;) were recruited and given 2000 IU vitamin D3 daily for 18 months. Anthropometrics and fasting blood were collected (0, 6, 12, 18 months) to monitor serum 25-hydroxyvitamin D using specific ELISA, and to determine metabolic profiles by standard methods.
Results
In all subjects there was a significant increase in mean 25-hydroxyvitamin D levels from baseline (32.2 ± 1.5 nmol/L) to 18 months (54.7 ± 1.5 nmol/L; p < 0.001), as well as serum calcium (baseline = 2.3 ± 0.23 mmol/L vs. 18 months = 2.6 ± 0.1 mmol/L; p = 0.003). A significant decrease in LDL- (baseline = 4.4 ± 0.8 mmol/L vs. 18 months = 3.6 ± 0.8 mmol/L, p < 0.001] and total cholesterol (baseline = 5.4 ± 0.2 mmol/L vs. 18 months = 4.9 ± 0.3 mmol/L, p < 0.001) were noted, as well as a significant improvement in HOMA-β function ( p = 0.002). Majority of the improvements elicited were more prominent in women than men.
Conclusion
In the Saudi T2DM population receiving oral Vitamin D3 supplementation (2000 IU/day), circulating 25-hydroxyvitamin D levels remained below normal 18 months after the onset of treatment. Yet, this “suboptimal” supplementation significantly improved lipid profile with a favorable change in HDL/LDL ratio, and HOMA-β function, which were more pronounced in T2DM females
Vitamin D supplementation as an adjuvant therapy for patients with T2DM: an 18-month prospective interventional study
Background: Vitamin D deficiency has been associated with impaired human
insulin action, suggesting a role in the pathogenesis of diabetes
mellitus type 2 (T2DM). In this prospective interventional study we
investigated the effects of vitamin D3 supplementation on the metabolic
profiles of Saudi T2DM subjects pre- and post-vitamin D supplementation
over an 18-month period.
Methods: T2DM Saudi subjects (men, N = 34: Age: 56.6 +/- 8.7 yr, BMI,
29.1 +/- 3.3 kg/m(2); women, N = 58: Age: 51.2 +/- 10.6 yr, BMI 34.3 +/-
4.9 kg/m(2);) were recruited and given 2000 IU vitamin D3 daily for 18
months. Anthropometrics and fasting blood were collected (0, 6, 12, 18
months) to monitor serum 25-hydroxyvitamin D using specific ELISA, and
to determine metabolic profiles by standard methods.
Results: In all subjects there was a significant increase in mean
25-hydroxyvitamin D levels from baseline (32.2 +/- 1.5 nmol/L) to 18
months (54.7 +/- 1.5 nmol/L; p<0.001), as well as serum calcium
(baseline = 2.3 +/- 0.23 mmol/L vs. 18 months = 2.6 +/- 0.1 mmol/L; p =
0.003). A significant decrease in LDL-(baseline = 4.4 +/- 0.8 mmol/L vs.
18 months = 3.6 +/- 0.8 mmol/L, p < 0.001] and total cholesterol
(baseline = 5.4 +/- 0.2 mmol/L vs. 18 months = 4.9 +/- 0.3 mmol/L, p <

function (p = 0.002). Majority of the improvements elicited were more
prominent in women than men.
Conclusion: In the Saudi T2DM population receiving oral Vitamin D3
supplementation (2000 IU/day), circulating 25-hydroxyvitamin D levels
remained below normal 18 months after the onset of treatment. Yet, this

Modest reversal of metabolic syndrome manifestations with vitamin D status correction : a 12-month prospective study
Numerous cross-sectional studies have noted significant negative associations between circulating levels of 25-hydroxyvitamin D and cardiometabolic risk factors, highlighting potential extraskeletal functions of this sterol hormone. Prospective studies, however, have been limited; and hence, no cause-and-effect relations can be inferred. This study aims to determine whether vitamin D status correction can reverse already established manifestations of the metabolic syndrome (MetS). A total of 59 adult nondiabetic, overweight, and obese Saudis (31 male, 28 female) were prospectively enrolled in this 1-year interventional study. Anthropometry and biochemical evaluation were performed, including determination of serum 25-hydroxyvitamin D, calcium, and phosphorous concentrations, as well as fasting blood glucose and lipid profile. Subjects were advised to regularly expose themselves to sunlight and increase intake of vitamin D-rich foods. All measurements were repeated 6 and 12 months later. At the initial baseline visit, the prevalence of both low high-density lipoprotein cholesterol and hypertension was significantly increased among patients with 25-vitamin D deficiency (P <.05), even after adjusting for sex and body mass index. Overall prevalence of MetS patients by the modified National Health and Nutrition Examination Survey Adult Treatment Panel III definition decreased from 25.2% to 13.0%; and this was largely due to a parallel decrease in the prevalence of low high-density lipoprotein cholesterol, triglycerides, and hypertension. Optimization of vitamin D status through sun exposure and increased intake of a vitamin D-rich diet can lead to an improved cardiometabolic profile, offering a promising nonpharmacologic approach in the prevention of MetS manifestations. © 2012 Elsevier Inc

Increased vitamin D supplementation recommended during summer season in the gulf region: a counterintuitive seasonal effect in vitamin D levels in adult, overweight and obese Middle Eastern residents
Purpose Seasonal variations in circulating vitamin D levels provide
vital information as to the most appropriate time to either start or
increase vitamin D supplementation to maintain optimal vitamin D levels.
In this follow-up study, we determined seasonal differences in serum
25(OH)-vitamin D (25(OH)D) levels, as well as parallel changes in
metabolic parameters, in a cohort of adult, overweight and obese Saudis.
Methods A total of 121 adult, overweight, obese, and consenting Saudis
aged 18-70 years were randomly recruited from four Primary Health Care
Centers in Riyadh, Saudi Arabia. They were divided according to the
season when baseline measurements were made [74 summer
(April-October); 47 winter (NovemberMarch)]. Anthropometrics were
obtained, and fasting blood samples were taken at baseline and every 3
months for 1 year. Fasting blood glucose, corrected calcium levels, and
lipid profiles were measured routinely. Serum 25(OH)-vitamin D was
quantified using a specific enzyme-linked immunosorbent assay (ELISA).
Results Age-and BMI-matched mean 25(OH)-vitamin D levels from the winter
group were significantly higher than those of the summer group (P < 0
001). In both groups, HDL-C levels improved significantly as
25(OH)-vitamin D levels increased with subsequent follow-ups, even after
adjusting for age, gender and BMI (P < 0 001).
Conclusion Seasonal differences in serum 25(OH)-vitamin D levels in
Saudi Arabia are counterintuitive, with circulating levels being higher
during the winter than the summer season. Increased vitamin D
supplementation is thus recommended to maintain optimal serum
25(OH)-vitamin D levels during the summer season
