Dietary Modifications in Critically-Ill Patients: A Comparison of Persian Medicine and Conventional Medicine Perspectives.

In Persian Medicine (PM) literature, a crisis is the culmination of the body's response to illness, which necessitates fundamental dietary modification to improve prognosis. In this narrative review, authentic PM textbooks as well as articles on diets for critically-ill patients (CIPs) obtained from PubMed and Google Scholar databases, were reviewed, and after gathering data, they were classified, coded, analyzed, and compared. In the acute phase, both PM and conventional medicine agree on relative food restriction, but PM lays a special focus on the use of meat in cases of weakness. There are both similarities and differences between PM and conventional medicine regarding nutritional recommendations in critical illness. For example, recommendations for food restriction and protein intake are similar in both schools, but recommendations for carbohydrate intake are different. The variables addressed and emphasized in PM require further evaluation in clinical trials.

Mizaj assessment in Multiple Sclerosis (MS) patients based on Persian Medicine.

OBJECTIVES: Increased incidence of Multiple Sclerosis (MS) calls for supporting complementary therapies in this field. Persian Medicine (PM) specialists present various assumptions to help patients through Mizaj (temperament) modification, but its confirmation requires scientific evidence. This study aimed at identifying the Mizaj of MS patients, and comparing it with their Mizaj before the onset of the disease, and with that of healthy people. METHODS: Forty-two MS and fifty-four healthy subjects participated in the study as case and control groups. General and brain Mizaj in patients were identified by five PM specialists before and after the onset of the disease. Mojahedi Mizaj Questionnaire (MMQ) was completed by the two groups. The validity of MMQ was assessed using Mizaj diagnosis by PM specialists as the gold standard. T-test, McNemar-Bowker, Wilcoxon, and Chi-square (χ 2) tests were used to compare the Mizaj of patients before and after the onset of the disease, and between the two groups (p<0.05). RESULTS: The sensitivity and specificity of MMQ for Hotness (75, 81%) and Coldness (75, 65%) were acceptable. There were no significant differences between patients and healthy subjects in terms of general Mizaj. But general and brain Mizaj of patients after developing MS inclined to coldness and dryness, although merely inclination of general Mizaj to coldness was significant (p=0.03). CONCLUSIONS: According to our results, the Mizaj of MS patients has an inclination toward coldness and dryness; Also, MMQ can be used as a validated scale for identifying the Mizaj of MS patients in future studies.

Periconceptional care and offspring health at birth and long term, from the perspective of Avicenna.

Periconceptional care such as lifestyle plays an important impact role in offspring health. The aim of the present study was to clarify the perspective of Avicenna on periconceptional care. Avicenna (980-1037 A.D.) was one of the outstanding Persian physicians, who made great contributions to the field of medical sciences, in particular, obstetrics. In advance, Avicenna's book, Canon of Medicine, was considered to find his perspectives on periconceptional care. Then, his ideas and theories were compared to the current findings by searching the keywords in main indexing systems including PubMed/MEDLINE, Scopus and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. Current investigations show that gamete quality, pregnancy outcome, and offspring health at birth and long term depend on both parents' lifestyle in pre- and periconceptional period, as well as the intrauterine environment. Avicenna believed that seminal fluid, sperm, ovum, and developing conditions in utero were influenced by the stages of food digestion and the function of some organs. On the other hand, food digestion and function of the organs also depend on each parent's lifestyle and environmental factors. He mentioned 6 principles of healthy lifestyle: exercise, nutrition, sleep and awareness, excretion of body wastes and retention of necessary materials, psychic features, as well as air and climate. Thus, a multicomponent healthy lifestyle should be considered by parents of child-bearing age in an appropriate period before and in early pregnancy as well as elimination of any disorders in parents, to give birth to more healthy offspring.

High rate of mutation in mitochondrial DNA displacement loop region in human colorectal cancer.

PURPOSE: Mitochondrial DNA mutations are found in many kinds of human cancer and the 1.1 kb displacement loop region has been identified as a "hot spot" for mutation in mitochondrial DNA of tumors. This study evaluated the mutation frequencies in hypervariable regions of mitochondrial displacement loop in patients with colorectal cancer. METHODS: We examined the frequency of mutations in the mitochondrial DNA displacement loop region of 40 colorectal cancer samples in comparison to 150 samples from people without any type of familial cancer history, by automated DNA sequencing. Alignment was made with the revised Cambridge Reference Sequence and any differences recorded as single base substitution, insertions, and deletions. RESULTS: Our results showed that the rate of displacement loop variations was higher in colorectal cancer patients than controls. Nineteen single nucleotide polymorphisms were found; among them eighteen occurred in the displacement loop region. CONCLUSIONS: Mutations in mtDNA D-loop region probably do not cause colorectal cancer but are more likely to be epiphenomena; patients with the high mtDNA variants are at a higher risk of colorectal cancer.
