Phytochemical Indole-3-carbinol (I3C) and Cervical Cancer

By Kyle J. Norton

Indole-3-carbinol is a phytochemical in the class of Indoles, by the breaking down of the glucosinolate glucobrassicin,  found abundantly in cabbage, kale, Brussels sprouts, rutabaga, mustard greens, broccoli, etc.

Cervical cancer is malignant neoplasm of the cervix uteri or cervical area caused by abnormal cells growth with alternation of cells DNA. According to the American Cancer Society's, in 2014, 12,360 new cases of invasive cervical cancer will be diagnosed with the death of  4,020 patients. The risk of cervical cancer is higher in Hispanic women followed by African-Americans, Asians and Pacific Islanders, and whites(a).
Depending to the stage and grade of the cancer, if the cancer is found in the early stahe, hysterectomy may not be needed. Other while  after sugery, chemotherapy including Cisplatin, Fluorouracil (5-FU), Mitomycin, Paclitaxel, Ifosfamide, Carboplatin, Bevacizumab and radiotherapy may be necesary, but with certain side effects. Emerging suggestion of a healthy and balanced diet to improve high serum levels of antioxidants may reduce cervical neoplasia risk(b)(c)  but other suggested that the role of diet and nutrition in the etiology of cervical cancer is not yet resolved(d) and Catalan Institute of Oncology study showed statistically nonsignificant inverse associations were also observed for leafy vegetables, root vegetables, garlic and onions, citrus fruits, vitamin C, vitamin E and retinol for invasive squamous cervical cancer (ISC)(e).

Dietary indole-3-carbinol (I3C) prevented the development of estrogen-enhanced cancers including breast, endometrial and cervical cancers(1) due to its antitumor activities associated not only with  regulation of estrogen activity and metabolism, but also modulation of ER transcription activity(2) through both antiestrogenic and estrogenic activity(3). In human cervical cancer cells, in comparison to diindolylmethane (DIM), a major in vivo product of indole-3-carbinol (I3C), both I3C and DIM caused accumulation of DNA strand breaks in three cervical cancer cell lines.  I3C  increased apoptosis in target tissues in vivo.(4). In mice study, according to the The Long Island Campus of Albert Einstein College of Medicine, showed to prevent the cervical-vaginal cancer promoted high doses of estrogen in these mices(5) and increased PTEN expression in the cervical epithelium of the transgenic mouse in vivo(6)

Obesity Complication of Varicose Vein

By Kyle J. Norton

Obesity is defined as a medical condition of excess body fat has accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese.

B. How to calculate your BMI index
BMI= weight (kg)/ height (m2)

Varicose Vein
is defined as a condition of enlarged and tortuous veins appearing blue and purple squiggly just under the skin. It can lead to blood flowing backwards, causing pain in standing or walking.

How Obesity associates with Varicose Vein
1. According to the study of "
Associations of moderate and severe overweight with self-reported illness and medical care in Dutch adults" by Seidell JC, de Groot LC, van Sonsbeek JL, Deurenberg P, Hautvast JG., posted in PubMed, researchers wrote that In men, severe overweight was associated with hypertension, especially in men under 50 years of age. In women, severe overweight was associated with hypertension, diabetes, varicose veins, asthma/bronchitis, and hemorrhoids. Increased utilization of medical care and medications were also associated with severe overweight. For moderately overweight subjects, these associations were less clear or absent.

2. In a study of "Epidemiology and risk factors for varicose veins among older people: cross-sectional population study in the UK" by Clark A, Harvey I, Fowkes FG., posted in PubMed, researchers found that Trunk varices occur very commonly in older age groups with increasing age, obesity and possibly female sex as risk factors. Associations found with DVT and hypertension were based on history alone and must be interpreted with caution.

3. According to the abstract of "The risk of congestive heart failure is increased in persons with varicose veins" by Mäkivaara LA, Ahti TM, Luukkaala T, Hakama M, Laurikka JO., posted in PubMed, researchers filed the result that Marginally higher prevalence of CHF was found in persons with varicose veins than in those without (2.9% vs. 1.9%) with OR 1.6 (1.0-2.3) and sex and age adjusted OR 1.2 (0.8-1.9). The incidence of CHF was higher in subjects with varicose veins than in others (4.9 vs. 2.6 per 1000 person-years) with IDR 1.9 (1.1-2.9) and sex and age adjusted IOR 2.5 (1.4-4.6). The result was further adjusted for body mass index, arterial disease and hypertension; multi-adjusted IOR for the incidence of CHF by varicose veins was 2.1 (1.1-4.0).

4. In the study of "Incidence of varicose veins in Finland" byMäkivaara LA, Jukkola TM, Sisto T, Luukkaala T, Hakama M, Laurikka JO., posted in PubMed, researchers wrote that 157 individuals reported new varicose veins during the follow-up. The overall incidence was 13.5 per 1000 person years (8.5 for men and 19.2 for women). Female sex was an independent and statistically significant risk indicator of varicose veins (adjusted odds ratio, OR 2.4). The incidence was significantly higher at the age of 50-55 years (OR 1.6). Higher body mass index seemed to be related to higher risk of new varicose veins (OR 1.2-1.8), but the association failed to reach statistical significance. The level of education did not affect the incidence.

5. In the observation during a five-year follow-up period were studied of the study of "The risk of congestive heart failure is increased in persons with varicose veins" by Mäkivaara LA, Ahti TM, Luukkaala T, Hakama M, Laurikka JO., posted in Pubmed, researchers filed the conclusion that Our longitudinal observation is consistent with the hypothesis that persons with varicose veins have a higher risk of CHF which is not mediated through sex, age, overweight, arterial disease or hypertension.

6. Etc.

 Treatments of Obesity and Varicose Vein
1. In the abstract of " [Varicose vein surgery and obesity--experience with a new Boazul cuff in leg circumference up to 90 cm]",[Article in German], by Hermanns HJ., posted in PubMed, researcher found that The use of the bloodless limb technique for varicose vein surgery is very comfortable, especially in cases of severe varicose veins and obesity. Maintenance of operation standards and utmost care of the cuffs lead to the successful use of this procedure.

2. According to the study of "Using the Boazul cuff to reduce blood loss in varicose vein surgery" by Robinson J, Macierewicz J, Beard JD., posted in PubMed, researchers concluded that use of the Boazul cuff significantly decreases the blood loss from the avulsion sites during routine varicose vein surgery, and may encourage the surgeon to perform more avulsions.

Obesity Complication of Chronic Venus Insufficiency

By Kyle J. Norton

Obesity is defined as a medical condition of excess body fat has accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese. 

How to calculate your BMI index
BMI= weight (kg)/ height (m2)

Chronic venous insufficiency or CVI is defined as a condition of swelling in the veins in the leg due to blood accumulation as result of the veins no longer working effective in pumping oxygen-depleting blood back to the heart.

 How Obesity associates with Chronic Venus Insufficiency
1. In the examination of 36 limbs in 23 nonobese individuals and 44 limbs in 22 obese individuals of the study of "Impact of obesity on venous hemodynamics of the lower limbs" by Willenberg T, Schumacher A, Amann-Vesti B, Jacomella V, Thalhammer C, Diehm N, Baumgartner I, Husmann M., posted in PubMed, researchers filed the conclusion that Lower limb venous flow parameters differ significantly between healthy obese and nonobese individuals. These findings support the mechanical role of abdominal adipose tissue potentially leading to elevated risk for both venous thromboembolism and chronic venous insufficiency.

2. According to the study of "Obesity and impaired venous function" by van Rij AM, De Alwis CS, Jiang P, Christie RA, Hill GB, Dutton SJ, Thomson IA., posted in PubMed, researchers found that The CEAP clinical stage of venous disease is more advanced in obese patients than non-obese patients with comparable anatomical patterns of venous incompetence. This may be the result of raised intra-abdominal pressure reported in previous studies, leading to greater reflux, increased vein diameter and venous pressures.

3. In the study of "Clinical presentation and patterns of venous reflux in Thai patients with chronic venous insufficiency (CVI)" by Kanchanabat B, Wongmahisorn Y, Stapanavatr W, Kanchanasuttirak P, Manomaiphiboon A., posted in PubMed, the group found that Thai patients with CVI were relatively young. Visible varicose veins, pain, oedema and inflammation were uncommon and most patients could maintain their usual activities despite advanced venous disease. An association with obesity was not common. Despite a low prevalence of a history of previous DVT, the prevalence of deep vein reflux was high and commonly combined with superficial venous reflux.

4. In the observation of 40,095 individuals from 803 registers of primary care in Poland of the study of "The influence of environmental factors in chronic venous insufficiency" by Jawien A., posted in PubMed, Jawien A. indicated that in the other developed countries was reported. It was more common in women, but female sex was not found to be a strong risk factor. Among the risk factors most closely associated with CVI were age, family history of varicose veins, and constipation, whatever the sex. This is in keeping with findings from recent epidemiologic studies. Obesity and lack of physical activity were strongly associated with CVI in women, more so than in men.

5. According to the study of "[Influence of environmental risk factors on the development of chronic vein insufficiency]" [Article in Polish] by Sudoł-Szopińska I, Błachowiak K, Koziński P., posted in PubMed, researchers wrote that this paper presents basic information on CVI epidemiology, etiopathogenesis and pathophysiology and also reviews the literature on the following CVI risk factors: obesity, lack of physical activity, dietary habits, including constipation, pregnancy, genetic factors as well as prolonged sedentary or upright position during job performance.

6. Etc.

Treatments of Obesity and Chronic Venus Insufficiency
1. According to the study of "In situ hemodynamics of perforating veins in chronic venous insufficiency" by Delis KT, Husmann M, Kalodiki E, Wolfe JH, Nicolaides AN., posted in PubMed, researchers found that In addition to an increase in diameter, perforator incompetence is characterized by significantly higher mean and peak flow velocities, volume flow, and venous volume displaced outward, and a lower flow pulsatility. Differences in early reflux enable a better hemodynamic stratification of incompetent perforators in CVI classes. In the presence of deep reflux, incompetent perforators sustain further hemodynamic impairment. In situ hemodynamics enable quantification of the function of perforators and can be used in the identification of the clinically relevant perforators and the impact of surgery.

2. In the study of "Effect of external valvuloplasty of the deep vein in the treatment of chronic venous insufficiency of the lower extremity" by Wang SM, Hu ZJ, Li SQ, Huang XL, Ye CS., posted in PubMed, researchers concluded that External valvuloplasty of the femoral vein combined with surgical repair of the superficial venous system improved the hemodynamic status of the lower limbs, restored valvular function more effectively, and achieved better outcomes than surgical repair of the superficial venous system alone.
