Dietary agents in the prevention of radiation-induced nausea and vomiting (RINV): review addressing the scientific observations, benefits, lacunae and future direction.

PURPOSE: Radiation-induced Nausea and Vomiting (RINV) is an important side effect and conservative estimates are that 50-80% of the patients undergoing curative radiotherapy (RT) will experience some sought of retching, nausea, and/or vomiting during the course of their treatment. Conventionally, antiemetic drugs like the 5-hydroxytryptamine receptor antagonists and steroids are the mainstay of treatment. However, the use of these agents, especially steroids, can cause side effects and thereby negate the proposed benefits. The antiemetic effects of Centella asiatica (Indian pennywort), Hippophae rhamnoides (Sea buckthorn), oil of Mentha spicata (Spearmint) and the rhizomes of Zingiber officinale (ginger) have been addressed. CONCLUSIONS: Results indicate that Indian pennywort, Sea buckthorn, Spearmint oil and ginger are beneficial in mitigating RINV. Also, of the four plants investigated in preclinical models of study, mint oil and ginger seem to be more useful and merit structured systematic translational studies to ascertain the benefit of these two agents.

Efficacy of Eicosapentaenoic Acid (EPA) Containing Protein Supplement in Preventing Weight Loss in Head and Neck Cancer Patients Undergoing Curative Radiotherapy: Retrospective Observations with Historical Controls.

Weight loss is a major issue in Head and Neck cancer (HNC) patients undergoing curative radiotherapy. The principal objective of the study was to observe whether eicosapentaenoic acid (EPA) containing protein supplement was effective in mitigating the weight loss during in hospitalized HNC undergoing curative radiotherapy. A retrospective study was performed based on clinical, treatment and nutritional data of 53 patients received EPA containing supplement during their curative radiotherapy from October 2014 to January 2015 and was compared with 88 historical control group of patients (October 2013 to June 2014) who had indigenous protein rich diet planned by the dietician in the period immediately before the implementation of providing EPA containing protein supplement to the patients. The data was stratified based on gender, age, weight, treatment modalities, stage and site of cancer and analysed using unpaired t test. A p value of < 0.05 was considered significant. The results indicate there was no significant difference in the patient tumor and clinical details. The results indicate that the percent change in weight loss was less in the EPA cohorts when calculated from weight (P < 0.006) and Body Mass Index (BMI) perspective (P < 0.003). Detail analysis suggested that beneficial effects were more in males (P < 0.01), people affected with oral cancer (P < 0.02), people below the age of 40 (P < 0.001), and in people with early stage cancer (P < 0.003). Cumulatively all these results suggest that administering EPA containing protein supplement was effective in arresting weight loss in HNC patients undergoing curative radiotherapy.

Link between Blood Cell-Associated Inflammatory Indices and Chemotherapy-Induced Hyperglycemia in Women Affected with Breast Cancer: Clinical Studies.

Krishna PrasadBackground Development of treatment-induced hyperglycemia/diabetes is a considerable problem in women undergoing chemotherapy for breast cancer. In this study, baseline levels of blood cell-associated inflammatory indices (BCAII) were analyzed to understand their role in the development of treatment-induced hyperglycemia and diabetogenesis. Materials and Methods This was a retrospective study, and information on women who were normoglycemic and nondiabetic and of women who were diabetic at the beginning of the treatment were collected from files. Demographic, pathology-related details, and complete blood profile were noted. Neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammatory index (SII) which indicate BCAII were calculated. Demographic details were subjected to frequency and percentage, while blood parameters were subjected to one-way analysis of variance followed by post hoc Bonferroni's multiple comparison tests. A p -value of <0.05 was considered significant. Results The results indicated that a significant difference in levels of total count ( p < 0.035), neutrophil, lymphocyte, and platelets ( p < 0.001) were observed. Regarding BCAII, when compared with women who were normoglycemic at the end of treatment, NLR, dNLR, PLR, and SII were significantly high for people who were known diabetics at the beginning of treatment ( p < 0.001). The dNLR ( p = 0.0008), PLR ( p < 0.001), and SII ( p < 0.001) were significant for people who developed secondary hyperglycemia/diabetes, while only dNLR was significant for people who progressed from normal to prediabetes stage ( p = 0.049) Conclusion To the best of the authors' knowledge, this is the first study that indicates difference in baseline BCAII and development of treatment-induced hyperglycemia/diabetes indicating that underlying low levels of inflammation may contribute to diabetogenesis in women affected with breast cancer.

Ayurvedic Drug Triphala in Combination with Providone Iodine Mitigates Radiation-Induced Mucositis in Head and Neck Cancer Patients without Affecting the Tumor Response.

Radiation-induced mucositis is a dose-limiting concern in the treatment of head and neck cancers (HNC). This study was conducted to determine the effectiveness of the Ayurvedic drug Triphala in reducing radiation-induced mucositis and influencing tumour control when combined with providone iodine. Data from patient files of HNC patients who received Triphala in conjunction with iodine or iodine alone over the course of curative radiotherapy (> 60 Gy) from May 2013 to February 2015 were extracted for this retrospective chart based study. Data was subjected to statistical analysis, X2 and unpaired t test using the Statistical Package for Social Sciences (SPSS), version 17 (IBM, Chicago, USA). When compared to iodine alone, the group that utilised Triphala gargling was very efficient in delaying mucositis, the extent of weight loss (p = 0.038), the incidence (p = 0.03), and the number (p = 0.02) of treatment breaks. However, it had no influence on the radiation-induced tumour response. According to the observations, Triphala coupled with iodine was more successful in preventing radiation mucositis, and without affecting the killing of tumour cells than iodine gargle alone. According to the authors, this is the first observation to demonstrate the value of combining providone iodine with Triphala in preventing radiation-induced oral mucositis.

Pharmacoeconomic Appraisal of Treating Head and Neck Cancer with Various Chemotherapy and Chemoirradiation Regimens Using Branded and Jan-aushadhi Drugs in India.

According to recent studies, head and neck cancers (HNC) make up a substantial proportion of all cancers in India and are proportionately high in the lower socioeconomic people practising tobacco and alcohol. Chemotherapy is a crucial component of treating HNC, and this study was carried out to determine the Cost Minimization Analysis (CMA) by comparing the price of the high and least expensive branded drugs marketed in India. This study was performed to understand the cost difference (CD), Cost ratio (CR) and percentage of cost variation (PCV) of both individual drugs and the standard anticancer regimens. The Current Index of Medical Stores was used to determine the costs of the most and least expensive branded medications and analysed. The results indicated that Paclitaxel-Cisplatin-5 Fluoruracil chemotherapy regimen exhibited the greatest variance in cost, with the Jan Aushadhi brand of medicine costing 8.1 times and 4.3 times less than the most expensive and cheapest branded drugs, respectively. The cost of the concurrent cisplatin regimen with Jan Aushadi Medicine was Rs 1764, Rs 3489.64 with the lowest branded drug, and Rs 8477 with the most expensive branded drug. Also when compared to Jan Aushadhi medication, the cost of Ciplatin was 4.8 times higher with the most expensive branded drug and 2 times higher with the least expensive branded drug. As far as the authors are aware of this is the first study that addresses the pharmacoeconomic appraisal of treating HNC with various chemotherapy and chemoirradiation regimens. This study will help oncologists, pharmacists, and healthcare workers comprehend the financial advantages of treating breast cancer with less expensive chemotherapeutic agents instead of brand-name medications.

"Cancer Education on Wheels," a Novel Cost-Effective Method in Creating Awareness in the Community: a Pilot Study.

Cancer education raises disease awareness, the value of early identification and importantly the need for prompt screening and treatment when diagnosed. In this study, an effort was made to understand how well a unique cancer education program, "Cancer Education on Wheels," transfers knowledge in general public in society. The community was shown prerecorded cancer awareness videos using a TV monitor, CD player, and speaker system mounted on an eight-seat Toyota Innova. Before and after seeing the video presentation, consenting volunteers filled out questionnaires asking about demographics and understanding of cancer. Frequency and percentage calculations were done on the demographic information and a Wilcoxon signed-rank test was run on the overall subject score. Data was stratified based on demographic information and compared by applying Kruskal-Wallis test and Mann-Whitney test. p values under 0.05 were regarded as significant. A total of 584 people completed the pre-test and post-test questionnaires. The Wilcoxon signed-rank test revealed a difference between the pre-test and post-test (3.29 ± 2.48 vs. 6.78 ± 3.52; P = 0.0001). The pre-test results showed that volunteers between the ages of 18 and 30; men; students; urban residents; single volunteers; graduates; people who had known a person/or family member with cancer; and people who were aware of the suffering cancer causes had a high baseline knowledge of cancer (p = 0.015 to 0.001). The post-test results show that participants who had less baseline scores like housewives and unemployed people performed better (p = 0.006 to 0.0001). The findings unambiguously demonstrated that "Cancer Education on Wheels" was successful in raising participants' awareness of cancer signs and screening. Additionally, the findings showed that volunteers who were aged, married, housewives, and unemployed had higher scores. Most importantly, this approach to cancer education is simple to organize and carry out in a local setting. It is also affordable and simple to execute using readily available technological equipment and manageable logistics. According to the authors' knowledge, this is the first study to use "Cancer Education on Wheels" to spread awareness of cancer throughout the neighborhood especially in budget constrained areas.

Social, Ethical and Treatment Related Problems Faced by Healthcare Workers in the Care of Head and Neck Cancer Patients: A Narrative Review from the Bioethics Consortium from India.

Head and neck cancer (HNC) presents a variety of ethical difficulties for an oncologist involved in screening, diagnosis, treatment, and rehabilitation that are challenging to address, especially for those professionals/people who are not trained in medical ethics. The bioethics department has spent the last ten years compiling information and rating the seriousness of numerous niche ethical concerns and their effects on healthcare professionals practising in India. Based on these findings, the current analysis makes an effort to outline the different challenges faced by oncologists when screening, diagnosing, treating, and rehabilitating people affected with HNC, particularly in a traditional nation like India. According to the authors, this is the first overview to address these issues from an Indian viewpoint, and it represents a small effort to document a crucial but unaddressed component of cancer treatment. It is hoped that these endeavours would aid in educating upcoming healthcare professionals on how to effectively handle the difficulties.

Neuroprotective effects of dietary plants and phytochemicals against radiation-induced cognitive and behavioral deficits: a comprehensive review of evidence and prospects for future research.

Exposure to ionizing radiation (IR) is a common occurrence in clinical practice and incidents involving nuclear detonation or nuclear reactor accidents. IR triggers cellular events that result in oxidative stress and damage to macromolecules, rendering it harmful. While the central nervous system (CNS) was once believed to be resistant to radiation, emerging evidence suggests that even small doses of IR can adversely impact the brain. Exposure to an unsafe dose of radiation can cause increased permeability of the blood-brain barrier (BBB), neuronal apoptosis, reduced neurogenesis, impaired synaptic plasticity, and cognitive dysfunction. In recent years, the potential benefits of dietary agents and phytochemicals for mental health and radiation-induced damage have been widely investigated. Despite this, few studies have explored the protective effects of plants against radiation-induced brain damage. Here, we present a review collating evidence on the beneficial effects of dietary plants on radiation-induced brain damage based on behavioral studies. Notably, Amaranthus paniculatus, Grewia asiatica, Lycium barbarum, and phytochemicals such as vitamin E, corilagin, curcumin, resveratrol, and ursolic acid have demonstrated potential in mitigating radiation-induced damage to the CNS. Furthermore, preliminary studies have indicated that alpha-tocopherol and the micronutrient selenium have neuroprotective effects in cancer survivors previously treated with radiation to the brain. This review focuses exclusively on behavioral outcomes to assess the impact of ionizing radiation on the CNS and the effectiveness of dietary plants and phytochemicals as neuroprotective agents against radiation-induced neuronal damage.

Fruits and their phytochemicals in mitigating the ill effects of ionizing radiation: review on the existing scientific evidence and way forward.

Although helpful in treating cancer, exposure to ionizing radiation can sometimes cause severe side effects, negating its benefit. In addition to its use in clinics, a nontoxic radioprotective agent can also be beneficial in occupational settings where humans are occupationally exposed for prolonged periods to low doses of radiation. Scientific studies using laboratory animals have shown that the fruits Aegle marmelos, Capsicum annuum, Citrus aurantium, Citrullus lanatus, Crataegus microphylla, Eugenia jambolana, Emblica officinalis, Garcinia kola, Grewia asiatica, Hippophae rhamnoides, Malus baccata, Malpighia glabra or Malpighia emarginata, Mangifera indica, Prunus domestica, Prunus avium, Prunus armeniaca, Psoralea corylifolia, Punica granatum, Solanum lycopersicum, Terminalia chebula, Vaccinium macrocarpon, Vitis vinifera and Xylopia aethiopica, and the phytochemicals gallic acid, ellagic acid, quercetin, geraniin, corilagin, ascorbic acid, hesperetin, ursolic acid, lycopene, naringin, hesperidin, rutin, resveratrol, ß-sitosterol, apigenin, luteolin, chlorogenic acid, caffeic acid, mangiferin, diosmin, ferulic acid, and kaempferol are effective in preventing radiation-induced ill effects. Clinical studies with Emblica officinalis and Punica granatum have also shown that fruits help mitigate radiation-induced mucositis, dermatitis, and cystitis. For the first time, the current review summarizes the beneficial effects of fruits and phytochemicals in mitigating radiation-induced damage, the underlying mechanisms and the existing lacunae for future studies to be undertaken for the benefit of humans and the nutraceutical and agri-based industries.

Usefulness of walkathon in improving knowledge on cancer: A cross-sectional study with the participants.

AIM: Globally, walkathon, a type of community event involving walking a determined distance to raise awareness and/or collect donations for a social cause is gaining a lot of public attention. This study was conducted to understand the usefulness of walkathon in creating cancer awareness among the participants. MATERIALS AND METHODS: This was a pre- and post-test study and was carried out on World Cancer Day on February 4, 2019 in Mangalore, Karnataka, India. The study subjects were the walkathon participants willing to be volunteers for the study. Differences in the answers were calculated by ascertaining the difference between the pretest and posttest using McNemar, Chi-square, or Fisher's exact test. A P < 0.05 was considered statistically significant. RESULTS: Pretest scores indicated most volunteers were aware of the role of tobacco and alcohol in cancer, while most were unaware of the importance of fruits and consumption of vegetables and sedentary lifestyle in the development of cancer. Posttest showed a significant increase in knowledge gain (P = 0.003 to <0.001). CONCLUSIONS: For the first time, this study shows Walkathon to be helpful in improving cancer knowledge in the participants. Walkathon is an inexpensive and joyful way to educate people and warrants further study on a range of medical and social themes affecting society to establish its usefulness in public health education.

Usefulness of structured teaching module in improving knowledge about cancer in Accredited Social Health Activist: A pilot study.

AIM: In India, the Accredited Social Health Activists (abbreviated as ASHA) are an important group of community health workers and are involved in initiating and maintaining health care programs in the rural communities they live. This study was conducted with a purpose to evaluate the effectiveness of a structured teaching module in improving knowledge on cancer cause, diagnosis, and treatment in the ASHA workers. MATERIALS AND METHODS: This was a cross-sectional pretest posttest study and was conducted from April 2017 to February 2020 with ASHA workers working in the various Primary Health Centers in Udupi and South Kanara districts of Karnataka and Kasargod district of Kerala in India after obtaining the permission from the medical officer in charge of the respective primary health centers. The participants were briefed about the study objective and also that confidentiality will be maintained. A validated investigator developed questionnaire consisting of 20 questions categorized into four domains (general, subject, diagnosis, and treatment aspects) was distributed to the willing volunteers before the start of the program. They were instructed to fill the pretest form before and posttest after the teaching program. Informed content was taken in a separate sheet and volunteers were informed not to write any personal or identification details. Resource persons with experience in cancer cause, diagnosis and treatment delivered the structured talk in the local language Kannada. The data collected from the filled questionnaires were subjected to frequency, percentage, mean, and standard deviation and appropriately subjected to Chi-square test or paired t-test. A P < 0.05 was considered statistically significant. RESULTS: The demographic detail suggest that majority of the women were Hindus (79.3%), married (93.7%), between the age of 31-40 (46.7%) and had only matriculation as the highest education (68%). The analysis of the pretest administration collected before the start of teaching program indicates that most participants were aware of self-breast examination (79.74%) and that cancer is a disease as old as human civilization (70.26%), while only 8.82% were unaware of which is the leading type of cancer in rural women. The results analyzed from posttest indicate that the highest percentage change (323.96%) was observed for domain on treatment aspects followed by for general (64.03%), diagnosis (56.70%), and subject (36.42%) aspect and was significant (P < 0.001). The total mean values changed from 6.48 ± 2.01 in pretest to 11.81 ± 2.15 in posttest indicating an increase of 5.33 ± 1.91 and percentage change of 82.25% (P < 0.001). The results also showed that 60.8% had average, while 39.2% had good increment in the knowledge at the end of the program. CONCLUSIONS: The observations of the current study indicate the usefulness of the structured teaching module in improving knowledge on cancer cause, diagnosis and treatment in the ASHA workers. It is proposed that with further training ASHA workers can be very useful in the propagation of cancer awareness and screening in the community they serve.

Apprehensions and Optimism among Dental Professionals during the COVID-19 Pandemic-A Nationwide Cross-Sectional Evaluation.

Globally, the pandemic of the coronavirus disease, which started in Wuhan, China, has become a major issue for public health. The COVID-19 epidemic notably causes health professionals to experience significantly more emotional stress than the general populace. The present study proposes to investigate the fear aspect in dentists in the initiation of clinical practice during these times. An online cross-sectional study was conducted among dental practitioners based on a pre-validated questionnaire. The data were expressed as frequency and percentage analyzed using the chi-square test using SPSS version 25. The data was obtained from 271 participants, where clinical practice after the first wave was mostly by freelancers (p-value = 0.01); most of whom were married (p-value = 0.065); 19.1% attached to institutes did not have changes in earnings; 28.1% of private practitioners had less than 10% reduction in cases. A total of 62% of private practitioners are concerned about the vaccine's preventative effects (p-value = 0.026), and 57% of private practitioners worry about being sued for the delay in treatment (p-value = 0.036). Only 33.1% of employees in institutions worry that becoming sick could endanger their family. As dentists continue to work their way through this pandemic, these pressures only occasionally have an impact on them. According to the researchers, this is the first study that has captured the anxiety and apprehensions that dental practitioners experienced during the height of the COVID-19 outbreak in India in April 2021. The study's findings demonstrate that the study population was generally upbeat and confident that they could quickly overcome their fear.

Dextran sodium sulfate alters antioxidant status in the gut affecting the survival of Drosophila melanogaster.

Inflammatory bowel disease (IBD) is a group of disorders characterized by chronic inflammation in the intestine. Several studies confirmed that oxidative stress induced by an enormous amount of reactive free radicals triggers the onset of IBD. Currently, there is an increasing trend in the global incidence of IBD and it is coupled with a lack of adequate long-term therapeutic options. At the same time, progress in research to understand the pathogenesis of IBD has been hampered due to the absence of adequate animal models. Currently, the toxic chemical Dextran Sulfate Sodium (DSS) induced gut inflammation in rodents is widely perceived as a good model of experimental colitis or IBD. Drosophila melanogaster, a genetic animal model, shares ~ 75% sequence similarity to genes causing different diseases in humans and also has conserved digestion and absorption features. Therefore, in the current study, we used Drosophila as a model system to induce and investigate DSS-induced colitis. Anatomical, biochemical, and molecular analyses were performed to measure the levels of inflammation and cellular disturbances in the gastrointestinal (GI) tract of Drosophila. Our study shows that DSS-induced inflammation lowers the levels of antioxidant molecules, affects the life span, reduces physiological activity and induces cellular damage in the GI tract mimicking pathophysiological features of IBD in Drosophila. Such a DSS-induced Drosophila colitis model can be further used for understanding the molecular pathology of IBD and screening novel drugs.

Utility of Indian Fruits in Cancer Prevention and Treatment: Time to Undertake Translational and Bedside Studies.

The World Health Organization predicts a 70% increase in cancer incidents in developing nations over the next decade, and it will be the second leading cause of death worldwide. Traditional plant-based medicine systems play an important role against various diseases and provide health care to a large section of the population in developing countries. Indigenous fruits and their bioactive compounds with beneficial effects like antioxidant, antiproliferative, and immunomodulatory are shown to be useful in preventing the incidence of cancer. India is one of the biodiversity regions and is native to numerous flora and fauna in the world. Of the many fruiting trees indigenous to India, Mango (Mangifera indica), Black plum (Eugenia jambolana or Syzygium jambolana), Indian gooseberry (Emblica officinalis or Phyllanthus emblica), kokum (Garcinia indica or Brindonia indica), stone apple or bael (Aegle marmelos), Jackfruit (Artocarpus heterophyllus), Karaunda (Carissa carandas) and Phalsa (Grewia asiatica), Monkey Jackfruit (Artocarpus lakoocha) and Elephant apple (Dillenia indica) have been shown to be beneficial in preventing cancer and in the treatment of cancer in validated preclinical models of study. In this review, efforts are also made to collate the fruits' anticancer effects and the important phytochemicals. Efforts are also made to address the underlying mechanism/s responsible for the beneficial effects of these fruits in cancer prevention and treatment. These fruits have been a part of the diet, are non-toxic, and easily acceptable for human application. The plants and some of their phytochemicals possess diverse medicinal properties. The authors propose that future studies should be directed at detailed studies with various preclinical models of study with both composite fruit extract/juice and the individual phytochemicals. Additionally, translational studies should be planned with the highly beneficial, well-investigated and pharmacologically multifactorial amla to understand its usefulness as a cancer preventive in the high-risk population and as a supportive agent in cancer survivors. The outcome of both preclinical and clinical studies will be useful for patients, the healthcare fraternity, pharmaceutical, and agro-based sectors.

Serum zinc status and the development of mucositis and dermatitis in head-and-neck cancer patients undergoing curative radiotherapy: A pilot study.

Background: Radiation-induced mucositis and dermatitis are severe side effects and compromise the health of the head-and-neck cancer patient undergoing treatment. Zinc supplementation during the course of the treatment is shown to have protective effects against both radiation-induced mucositis and dermatitis. The aim of this study was to understand whether the level of serum zinc has an effect on the development of mucositis and dermatitis. Materials and Methods: This was noninterventional study where the levels of serum zinc were ascertained before the start of treatment by spectrophotometric methods. The patients were treated every day with no more than one fraction of 2 Gy per day, five times a week without any intended gaps for a planned target dose of 60-70 Gy (6-7 consecutive weeks). The patients were assessed for radiation-induced dermatitis and mucositis in accordance with the standard guidelines. The association between the levels of serum zinc with the development of different grades of mucositis and dermatitis (on the day of development) was ascertained using the Pearson correlation coefficient (r). A statistical value of P < 0.05 was considered to be statistically significant. Results: A total of 52 consecutive patients satisfying the inclusion criteria were enrolled. The results indicate that serum zinc levels showed a significant correlation (r = 0.29; P < 0.038) for Grade 1, while it was insignificant for Grades 2 and 3. For dermatitis, a significant correlation for all the grades (Grade 1 [r = 0.28; P < 0.043]; Grade 2 [r = 0.39; P < 0.006]; and Grade 3 [r = 0.49; P < 0.047]) was observed. Conclusions: For the first time, the results of this pilot study indicate that the serum level of zinc had an inverse association with the early development of mucositis and dermatitis, with better effects seen in dermatitis where it was also effective in Grades 2 and 3.

Evaluation of the anti-hyperlipidemic effects of Triphala in high fat diet fed rats: Studies with two combinations.

Background: Hyperlipidemia is one of the major risk factors for coronary heart disease and stroke. Triphala, a polyherbal Ayurvedic formulation made from dried fruits of Haritaki (Terminalia chebula Retz.), Bibhitaki (Terminalia bellirica Roxb.), and Amalaki (Phyllanthus emblica Gaertn.) has been suggested to be useful in mitigating hyperlipidemia. In the Ayurveda texts, depending on the patient's condition and body type, Triphala is formulated and used in one of the two combination (1:1:1 and 1:2:4 of individual constituents) forms. Aims: The present study aimed at evaluating the efficacy of two combinations (1:1:1 and 1:2:4 of individual constituents) of Triphala against high fat diet induced-hyperlipidemia in rats. Materials and method: Hyperlipidemia was induced in Spraque-Dawley albino rats by feeding them with high fat diet. The animals were concomitantly administered with graded dose of one of the two combination (combination of Haritaki, Bibhitaki, and Amalaki in ratio of 1:1:1 or 1:2:4, respectively) of Triphala (250, 500, or 1000 mg/kg body wt.) or atorvastatin. The animals were sacrificed on day 22 and serum was processed for lipid profile and the liver for lipid peroxidation. The statistical analysis was performed by the mean analysis of variance followed by Dunnet's test. Results: The results indicated that when compared to placebo group, levels of serum total cholesterol, and triglyceride were significantly lower, while high-density lipoprotein cholesterol increased in both the Triphala combination and atorvastatin groups. Of the two groups of Triphala, the formulation having 1:2:4 ratio was better than the 1:1:1. The group having highest drug dose (1000 mg/kg body wt.) of 1:2:4 formulation was better than atorvastatin in rectifying high fat diet-induced dyslipidemia and the atherogenic index was equal to that of atorvastatin. Conclusions: The results of the study indicate that of the two Triphala formulations, the 1:2:4 ratio was better than the 1:1:1 ratio for anti-hyper-lipidemic effects.

Medicinal plants in mitigating electromagnetic radiation-induced neuronal damage: a concise review.

Although the evidence is inconclusive, epidemiological studies strongly suggest that increased exposure to electromagnetic radiation (EMR) increases the risk of brain tumors, parotid gland tumors, and seminoma. The International Agency for Research on Cancer (IARC) has classified mobile phone radiofrequency radiation as possibly carcinogenic to humans (Group 2B). Humans being are inadvertently being exposed to EMR as its prevalence increases, mainly through mobile phones. Radiation exposure is unavoidable in the current context, with mobile phones being an inevitable necessity. Prudent usage of medicinal plants with a long history of mention in traditional and folklore medicine and, more importantly, are safe, inexpensive, and easily acceptable for long-term human use would be an appealing and viable option for mitigating the deleterious effects of EMR. Plants with free radical scavenging, anti-oxidant and immunomodulatory properties are beneficial in maintaining salubrious health. Green tea polyphenols, Ginkgo biloba, lotus seedpod procyanidins, garlic extract, Loranthus longiflorus, Curcuma amada, and Rosmarinus officinalis have all been shown to confer neuroprotective effects in validated experimental models of study. The purpose of this review is to compile for the first time the protective effects of these plants against mobile phone-induced neuronal damage, as well as to highlight the various mechanisms of action that are elicited to invoke the beneficial effects.

Indian Indigenous Fruits as Radioprotective Agents: Past, Present and Future.

Ionising radiation has been an important modality in cancer treatment and its value is immense when surgical intervention is risky or might debilitate/adversely affect the patient. However, the beneficial effect of radiation modality is negated by the damage to the adjacent healthy tissue in the field of radiation. Under these situations, the use of radioprotective compounds that can selectively protect normal tissues against radiation injury is considered very useful. However, research spanning over half a century has shown that there are no ideal radioprotectors available. The United States Food and Drug Administration (FDA or USFDA) approved amifostine, or WR-2721 (Walter Reed-2721) [chemically S-2-(3-aminopropyl-amino) ethyl phosphorothioic acid] is toxic at their optimal concentrations. This has necessitated the need for agents that are safe and easily acceptable to humans. BACKGROUND: Dietary agents with beneficial effects like free radical scavenging, antioxidant and immunomodulatory effects are being recognized as useful and have been investigated for their radioprotective properties. Studies in these lines have shown that the fruits of Aegle marmelos (stone apple or bael), Emblica officinalis or Phyllanthus emblica (Indian gooseberry/amla), Eugenia jambolana or Syzygium jambolana (black plum/jamun), Mangifera indica (mango) and Grewia asiatica (phalsa or falsa) that are originally reported to be indigenous to India have been investigated for their usefulness as radioprotective agents. OBJECTIVE: The objective of this review is to summarize the beneficial effects of the Indian indigenous fruits, stone apple, mango, Indian gooseberry, black plum, and phalsa, in mitigating radiation-induced side effects, emphasize the underlying mechanism of action for the beneficial effects and address aspects that merit detail investigations for these fruits to move towards clinical application in the near future. METHODS: The authors data-mined Google Scholar, PubMed, Embase, and the Cochrane Library for publications in the field from 1981 up to July 2020. The focus was on the radioprotection and the mechanism responsible for the beneficial effects, and accordingly, the articles were collated and analyzed. RESULTS: This article emphasizes the usefulness of stone apple, mango, Indian gooseberry, black plum, and phalsa as radioprotective agents. From a mechanistic view, reports are suggestive that the beneficial effects are mediated by triggering free radical scavenging, antioxidant, anti-mutagenic and anti-inflammatory effects. CONCLUSION: For the first time, this review addresses the beneficial effects of mango, Indian gooseberry, black plum, stone apple and phalsa as radioprotective agents. The authors suggest that future studies should be directed at understanding the selective radioprotective effects with tumor-bearing laboratory animals to understand their usefulness as radioprotective drug/s during radiotherapy and as a food supplement to protect people from getting exposed to low doses of radiation in occupational settings. Phase I clinical trial studies are also required to ascertain the optimal dose and the schedule to be followed with the standardized extract of these fruits. The most important aspect is that these fruits, being a part of the diet, have been consumed since the beginning of mankind, are non-toxic, possess diverse medicinal properties, have easy acceptability, all of which will help take research forward and be of benefit to patients, occupational workers, agro-based sectors and pharma industries.

Aqueous Extract of Emblica officinalis Linn (Indian gooseberry) in Combination with Iodine is More Efficacious than Iodine Alone in Mitigating Mucositis in Head and Neck Cancer Patients Undergoing Curative Radiotherapy: Retrospective Observations.

Mucositis is a very painful unavoidable and common side effect in head and neck cancer patients undergoing curative radiotherapy and can affect the planned treatment. In this study, attempt is made at understanding the efficacy of Emblica officinalis Linn (amla) when combined with providone iodine in mitigating radiation-induced mucositis, weight loss and tumor control. This was a retrospective chart based study and was carried out by extracting the data from the files of patients with cancer of head and neck who used amla in combination with iodine or iodine alone during the course of the curative radiotherapy (> 60 Gy). The data was entered in to Microsoft excel and subjected to statistical analysis using SPSS 17 software. The results indicate that when compared with iodine alone, the group where iodine and amla gargling were used was very effective in delaying mucositis, reduced incidence of intolerable mucositis (P = 0.027), quantitative grade of weight loss (P = 0.016), incidence of severe weight loss (P = 0.03) without affecting tumor response. The results suggest that when compared with iodine alone, amla when combined with iodine was more effective in mitigating radiation mucositis and by not interfering with the tumor cell kill. As far as the authors are aware of this is the first study that shows the usefulness of combining iodine with Amla in mitigating radiation-induced mucositis.

Dietary agents in mitigating chemotherapy-related cognitive impairment (chemobrain or chemofog): first review addressing the benefits, gaps, challenges and ways forward.

Chemobrain or chemofog is one of the important but less investigated side effects, where the cancer survivors treated with chemotherapy develop long-term cognitive impairments, affecting their quality of life. The biological mechanisms triggering the development of chemobrain are largely unknown. However, a literature study suggests the generation of free radicals, oxidative stress, inflammatory cytokines, epigenetic chromatin remodeling, decreased neurogenesis, secretion of brain-derived neurotropic factor (BDNF), dendritic branching, and neurotransmitter release to be the cumulative contributions to the ailment. Unfortunately, there is no means to prevent/mitigate the development and intensity of chemobrain. Given the lack of effective prevention strategies or treatments, preclinical studies have been underway to ascertain the usefulness of natural products in mitigating chemobrain in the recent past. Natural products used in diets have been shown to provide beneficial effects by inhibition of free radicals, oxidative stress, inflammatory processes, and/or concomitant upregulation of various cell survival proteins. For the first time, this review focuses on the published effects of astaxanthin, omega-3 fatty acids, ginsenoside, cotinine, resveratrol, polydatin, catechin, rutin, naringin, curcumin, dehydrozingerone, berberine, C-phycocyanin, the higher fungi Cordyceps militaris, thyme (Thymus vulgaris) and polyherbal formulation Mulmina™ in mitigating cognitive impairments in preclinical models of study, and also addresses their potential neuro-therapeutic mechanisms and applications in preventing/ameliorating chemobrain.
