Also the inability of ketone bodies metabolization due to various defciencies in mitochondrial enzymes is the major metabolic changes discovered in malignant cells. Therefore, administration of a ketogenic diet (KD) which is based on high in fat and low in carbohydrates might inhibit tumor growth and provide a rationale for therapeutic strategies. So, we conducted this systematic review to assess the effects of KD on the tumor cells growth and survival time in animal studies. All databases were searched from inception to November 2015. We systematically searched the PubMed, Scopus, Google Scholars, Science Direct and Cochrane Library according to the Preferred Reporting Items for<br />Systematic Reviews and Meta‑Analyses statement. To assess the quality of included studies we used SYRCLE’s RoB tool. 268 articles were obtained from databases by primary search. Only 13 studies were eligible according to inclusion criteria. From included studies, 9 articles indicate that KD had a<br />benefcial effect on tumor growth and survival time. Tumor types were included pancreatic, prostate, gastric, colon, brain, neuroblastoma and lung cancers. In conclusions, although studies in this feld are rare and inconsistence, recent fndings have demonstrated that KD can potentially inhibit the malignant cell growth and increase the survival time. Because of differences physiology between animals and humans, future studies in cancer patients treated with a KD are needed.<br /></span><strong></strong></p><p><strong><span class="fontstyle2">Keywords: </span></strong><span class="fontstyle3">Cancer, ketogenic diet, survival, tumor growth</span> <br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" /></p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1792http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1792/2081International Journal of Preventive Medicine (Int J Prev Med)2008-78020420170527Does Alpha‑lipoic Acid Supplement Regulate Blood Pressure?

This systematic review of randomized clinical trials was conducted to summarize the evidence on the effect of ALA on BP. PubMed,<br />SCOPUS, and Google Scholar databases were searched based on MESH term (“Thioctic acid” in combination with “Hypertension” and “Blood pressure”) to identify related papers published up to December 2015. We summarized the results of the relevant studies in this review. In total, nine<br />studies included in this review, seven parallel‑designed trials and two crossover‑designed trials. The results of parallel‑designed studies are inconsistent. Five studies indicate no signifcant effects for ALA supplementation on BP, but two trials show effects on BP. Unlike parallel‑designed trials, two crossover‑designed trials have shown similar results and both report no effect for ALA on BP. Several studies investigated the effect of ALA on BP. Most of the papers show no signifcant<br />effect for supplementation and the studies have shown that associations are limited. However, these fndings are limited and there is a need for further and more accurate researches to be clarifed.<br /></span><span class="fontstyle2"><strong>Keywords</strong>: </span><span class="fontstyle3">Alpha‑lipoic acid, diastolic blood pressure, hypertension, systolic blood pressure, thioctic acid</span> <br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;" />http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1790http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1790/2083International Journal of Preventive Medicine (Int J Prev Med)2008-78020420170506Penile Inflammatory Skin Disorders and the Preventive Role of Circumcision17891789ENDepartment of Physiology, School of Medical Sciences and Bosch Institute, University of Sydney, New South Wales 2006,Department of Medicine, University of Washington School of Medicine, VA Puget Sound Health Care System, Section of Urology,
Seattle, Washington 9810820170506<p>Penile inflammatory skin conditions such as balanitis and posthitis are common, especially in uncircumcised males, and feature prominently in medical consultations. We conducted a<br />systematic review of the medical literature on PubMed, EMBASE, and Cohrane databases using keywords “balanitis,” “posthitis,” “balanoposthitis,” “lichen sclerosus,” “penile inflammation,” and<br />“inflammation penis,” along with “circumcision,” “circumcised,” and “uncircumcised.” Balanitis is the most common inflammatory disease of the penis. The accumulation of yeasts and other<br />microorganisms under the foreskin contributes to inflammation of the surrounding penile tissue. The clinical presentation of inflammatory penile conditions includes itching, tenderness, and pain. Penile inflammation is responsible for significant morbidity, including acquired phimosis, balanoposthitis, and lichen sclerosus. Medical treatment can be challenging and a cost burden to the health system. Reducing prevalence is therefore important. While topical antifungal creams can be used, usually<br />accompanied by advice on hygiene, the definitive treatment is circumcision. Data from meta‑analyses showed that circumcised males have a 68% lower prevalence of balanitis than uncircumcised males and that balanitis is accompanied by a 3.8‑fold increase in risk of penile cancer. Because of the high<br />prevalence and morbidity of penile inflammation, especially in immunocompromised and diabetic patients, circumcision should be more widely adopted globally and is best performed early in infancy.</p><p><strong>Keywords</strong>: Balanitis, circumcision male, foreskin, infection, inflammation, lichen sclerosus</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1789http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1789/2078International Journal of Preventive Medicine (Int J Prev Med)2008-78020420170527Clinical Effcacy and Safety of Methotrexate versus Hydroxychloroquine in Preventing Lichen Planopilaris Progress: A Randomized Clinical Trial17941794ENDepartment of Dermatology, Skin Diseases and Leishmaniasis Research Center, School of Medicine, Isfahan University of Medical Sciences, IsfahanDepartment of Dermatology, Skin Diseases and Leishmaniasis Research Center, School of Medicine, Isfahan University of Medical Sciences, IsfahanDepartment of Dermatology, Skin Diseases and Leishmaniasis Research Center, School of Medicine, Isfahan University of Medical Sciences, IsfahanDepartment of Biostatics and Epidemiology, School of Public Health, Isfahan University of Medical Sciences, Isfahan20170527<p><strong><span class="fontstyle0">Background: </span></strong><span class="fontstyle2">Lichen planopilaris is an inflammatory cicatricial alopecia, and its management is a challenge for dermatologists.

Implementing interventions to reduce physical inactivity needs to assess related determinants. This study aims<br />to assess factors associated with screen time in a national sample of children and adolescents.</p><p><strong>Methods</strong>: This nationwide study was conducted among 14,880 students aged 6–18 years. Data collection was performed using questionnaires and physical examination. The World Health<br />Organization‑Global School Health Survey questionnaire was used. Logistic regression analysis was used to examine the relationship between demographic variables, socioeconomic status (SES), family structure, physical activity, unhealthy eating habits, body mass index, and mental distress with screen time.</p><p><strong>Results</strong>: The participation rate was 90.6% (n = 13,486), 50.8% were male, and 75.6% lived in urban areas. Mean (standard deviation) age of participants was 12.47 (3.36) years.<br />The SES, eating junk foods, urban residence, and age had significant association with screen time, watching television (TV), and computer use (P < 0.05). With increasing number of children, the odds ratio of watching TV reduced (P < 0.001). Statistically, significant association existed between obesity and increased time spent watching TV (P < 0.001). Girls spent less likely to use computer and to have prolonged screen time (P < 0.001). Participants in the sense of worthlessness were<br />less likely to watch TV (P = 0.005).
