AI Article Synopsis
- The study aimed to assess how intestinal malabsorption affects iodine levels in patients with short gut syndrome receiving total parenteral nutrition, compared to healthy controls and patients with normal digestion.
- A total of 27 subjects were evaluated for iodine intake from food and nutrition solutions, along with measurements of urinary iodine excretion and other health markers.
- Results showed no significant differences in iodine intake or excretion among the groups, indicating that dietary iodine in Brazil is adequate for maintaining iodine levels in patients with short gut syndrome.
Article Abstract
Objective: We evaluated the influence of intestinal malabsorption on iodine status in patients who had short gut syndrome and received total parenteral nutrition (group I) compared with control subjects who had eutrophia (group II) and patients who had other illnesses but normal digestive tracts (group III).
Methods: Twenty-seven subjects were studied. Iodine intake was determined by the measurement of iodine in ingested food and in parenteral nutrition solutions. Urinary iodine excretion was measured by the Sandell-Kalthoff reaction. Urinary creatinine, anthropometric, and thyroid hormone functions were also determined.
Results: Daily iodine intakes were 658 +/- 125 (mean +/- standard deviation), 573 +/- 204, and 629 +/- 208 microg for groups I, II, and III, respectively. Daily urinary iodine excretion levels were 399 +/- 308, 439 +/- 192, and 370 +/- 268 microg and ratios of urinary iodine (micrograms) to creatinine (grams) were 614 +/- 349, 354 +/- 142, and 483 +/- 292, respectively. There were no statistically significant differences across groups.
Conclusion: In Brazil the iodine provided by food, including iodized salt, has been sufficient to maintain iodine status in patients with short gut syndrome.

A Sentinel Survey in Remote Western Thailand Indicates that School-Aged Children and Reproductive-Aged Women of the Indigenous Pwo Karen Community are Iodine Sufficient.
Br J Nutr

Institute of Nutrition, Mahidol University, Salaya, Nakhon Pathom 73170, Thailand.
Indigenous peoples are often not routinely included in iodine programs because of language barriers and remote access, and may thus be at higher risk of iodine deficiency disorders, which could adversely impact their quality of life. We conducted this cross-sectional study in the remote Pwo Karen community of Thailand to determine the urinary iodine concentration (UIC) of school-aged children (SAC) and women of reproductive age (WRA) and investigate the iodine content in household salt. We measured UIC in spot urine samples from healthy SAC and WRA, administered a questionnaire, estimated daily iodine intake and collected household salt samples to determine salt iodine concentration.

Background: The lactation period is a crucial period where the nutritional status and the mother's environment influence milk production, impacting organ differentiation, function, and structure in the baby's body.
Aim: The study aimed to determine the impact of providing lactating rats with quail egg supplements enriched with marine macroalgae on their physiological condition (blood cells, lipids, blood glucose, antioxidant activity, and prolactin hormone levels) and the growth of their offspring.
Methods: The study involved 25 lactating Sprague Dawley white rats aged 3 months old and weighing approximately 200 g divided into five treatment groups thus; T0 as the control, T1 with quail eggs enriched with commercial feed, T2 with quail eggs enriched with 3% of marine macroalgae, T3 with quail eggs enriched with 4% of marine macroalgae, and T4 with quail eggs enriched with 5% of marine macroalgae, which received one quail egg for 21 days.
Comparing the efficacy of tadalafil and tamsulosin for managing erectile dysfunction and lower urinary tract symptoms in prostate brachytherapy patients: a prospective study.

Introduction: Adverse events, such as erectile dysfunction (ED) and lower urinary tract symptoms (LUTS), are significant concerns in prostate cancer (PCa) patients treated with Iodine 125 (I-125) low-dose rate (LDR) prostate brachytherapy (PB). Alpha antagonists and phosphodiesterase-5 inhibitors are used to manage these events. The present study compared the efficacy of low-dose tadalafil with that of tamsulosin for concomitant ED and LUTS in PCa patients treated with I-125 LDR PB.

Background: Spread through air spaces (STAS) is a well-established factor associated with poor oncological outcomes in patients undergoing surgery for solid lung adenocarcinoma. There could potentially be a disparity in iodine uptake between patients with positive and negative airway spread of solid lung adenocarcinoma.
Purpose: To explore the associations and find correlations of iodine uptake with STAS status in patients who underwent surgery for solid lung adenocarcinoma.
Toward Supplementation Guidelines for Vegan Complementary Feeding.

Previously published recommendations for vegetarian (including vegan) diets for children have highlighted the need for vitamin B12 supplementation. Increased attention to several other key nutrients (including iodine, vitamin D, calcium, and iron) has also been recommended. However, an overview focusing on supplementation guidelines, specifically for vegan infants, has not been published, and a potential requirement for iodine and/or selenium supplementation in (some) vegan infants has not been discussed.
