Abstract
Research in recent years have provided rapid advances in biogeographic and taxonomic documentation of sea slugs around the world. However, efforts are lacking in surveying most coastlines and habitats in South-East Asia. Recent studies from the Gulf of Thailand have indicated that a wealth of unexplored sea slug diversity and ecology may be gained from an investigation of soft sediment habitats beyond the reef slopes. Additionally, the waters of Koh Tao have been found to host regionally high levels of sea slug diversity with several species awaiting taxonomic clarification. In this work the initial findings of an expanded survey effort from the waters around Koh Tao are provided, with the identity of two soft sediment-associated sacoglossan species in the family Plakobranchidae being investigated. By integrating morphological and molecular analyses, the species Plakobranchusnoctisstellatussp. nov. and Elysiaaowthaisp. nov. are described and species complexes surrounding Plakobranchusocellatus van Hasselt, 1824 and Elysiajaponica Eliot, 1913 are discussed. The topics of morphological variability and the cryptic species problem are also discussed.

Abstract
A 25-year-old female, with systemic lupus erythematosus and antiphospholipid antibody syndrome, presented with exertional dyspnoea. Echocardiography showed a large (2.0 cm × 1.1 cm), echogenic, heterogeneous mass in the left ventricular outflow tract, under the aortic valve, attached to the ventricular aspect of the anterior mitral leaflet. Tiny flagellar, frond-like structures were seen attached to the surface of the mass. There was mitral regurgitation. These echocardiographic features were suggestive of a papillary fibroelastoma, but the histopathology of the excised mass revealed it to be a thrombus, which was consistent with a diagnosis of non-bacterial thrombotic endocarditis (NBTE). This case represents a rare histopathologically confirmed NBTE presenting as an unusually large mass in the left ventricular outflow tract.

Abstract
Recent studies revealed that reef corals can eat large-sized pelagic and benthic animals in addition to small planktonic prey. As follow-up, we document natural ingestion of sea slugs by corals and investigate the role of sacoglossan sea slugs as possible prey items of scleractinian corals. Feeding trials were carried out using six sacoglossan species as prey, two each from the genera Costasiella, Elysia and Plakobranchus, and four free-living solitary corals (Danafungia scruposa, Fungia fungites, Pleuractis paumotensis and Heteropsammia cochlea) as predators. Trials were carried out under both in-situ and ex-situ conditions with the aim to observe ingestion and assess signs of prey consumption based on tissue loss of prey individuals over time. Significant differences were observed in both ingestion time and consumption state of prey between prey species, with three of them being ingested more rapidly and preferentially consumed over the others. Additionally, prey size was found to be a significant factor with larger prey (>12 mm) being ingested more slowly and rarely than smaller ones (<6 mm and 6-12 mm). Comparisons of consumption capability among predators showed no significant difference with all coral species showing similar preferences for prey species. While no specific mechanism of prey capture is proposed, we also document instances of kleptoparisitism and resuspension of prey items by wrasses. This study highlights the important distinction between opportunistic prey capture and true predation events.

Abstract
An integrative molecular and morphological study is presented for the family Unidentiidae. Molecular phylogenetic analyses were conducted with the inclusion of all previous and newly obtained molecular data for the family Unidentiidae Millen Hermosillo 2012. A new species of the genus Unidentia Millen Hermosillo 2012, U. aliciae sp. nov., is described from Thailand as part of an inventory of sea slugs at Koh Tao. All up-to-date available morphological data for the species of the genus Unidentia is for the first time summarized. Morphological differences among the different species of Unidentia are clarified showing that every species has its own distinguishable morphological traits. According to the new molecular and morphological data, the family Unidentiidae is re-confirmed as a well-supported taxon of the aeolidacean nudibranchs. The taxonomy and phylogeny of the Aeolidacea in the light of the family Unidentiidae is briefly discussed and necessity of a fine-scale and narrowly-defined taxa approach instead of a ''superlumping'' one is highlighted.

Abstract
Morphological and molecular data are presented for the first time in an integrative way for the genus Myja Bergh, 1896. In accordance with the new molecular phylogenies, the traditional Facelinidae is paraphyletic. Herein is presented the phylogenetic placement of true Facelinidae s. str., including the first molecular data for F.auriculata (Müller, 1776), type species of the genus Facelina Alder & Hancock, 1855. The taxonomic history of F.auriculata is reviewed. The genus Myja is related to the clade Facelinidae s. str., but shows disparate morphological traits. Two new species of the genus Myja, M.karinsp. n., and M.hyotansp. n., are described from the Pacific waters of Japan (middle Honshu), and M.cf.longicornis Bergh, 1896 is investigated from Thailand. According to molecular analysis and review of available morphological information, the genus Myja contains more hidden diversity. The family-level relationship within aeolidacean nudibranchs with emphasis on the family Facelinidae is outlined. The problem of the relationship between Facelinidae Bergh, 1889 and Glaucidae Gray, 1827 is discussed. The family Glaucidae has precedence over Facelinidae and is phylogenetically related to the core group of Facelinidae s. str., but has a profoundly modified aberrant external morphology, thus making a purely molecular-based approach to the taxonomy an unsatisfactory solution. To accommodate recently discovered hidden diversity within glaucids, the genus Glaucilla Bergh, 1861 is restored. The family Facelinidae s. str. is separate from, and not closely related to, a clade containing the genera Dondice Marcus, 1958, Godiva MacNae 1954, Hermissenda Bergh, 1879, and Phyllodesmium Ehrenberg, 1831 (= Myrrhine Bergh, 1905). The oldest valid available name for the separate ex-facelinid paraphyletic clade that contains several facelinid genera is Myrrhinidae Bergh, 1905, and resurrection of this family name under provision of the ICZN article 40.1 can preliminarily solve the problem of paraphyly of the traditional Facelinidae. “Facelinidae” s. l. needs to be further divided into several separate families, pending further study.

Abstract
Background: With details on various cancers and recent advances in cancer prevention, a Web portal was developed to create awareness and value added education among Web-users in general population in villages, small towns and large cities of India. Aim: The Web portal aims at bringing awareness at the 3 levels of health related education program delivery success/efficacy triangle. The 1st level is cognitive learning of just being aware of cancer & basic knowledge. The 2nd level is a positive effect to be able to adopt life style changes that will lead to habit changes in diet, substance abuse and other life style habits and adherence to prescribed treatment. The 3rd level is actual behavioral change. Methods: A mixed methods study design incorporating etic-emic & qualitative research methodology and quantitative cross-sectional methods. We also used focused group discussions and in-depth interviews as part of qualitative study designs. Results: On the basis of data from the 100 participants, the Web portal was found to have improved attitudes toward accessing information related to cancer in participants. There was also an increase in the knowledge of the people, both general population and level 1 healthcare worker as compared with their previous knowledge about cancer. Also found was improvement in knowledge about the prevalent cancers, their screening procedures and general measures of prevention and treatment. Conclusion: On the basis of participants evaluated, we found that the Web portal may have a positive effect on cancer awareness of general population. Participants found the Web portal as a relevant tool to access information in the feedback. The comprehensive data which will be available after feedback from all participants, will help in understanding the nature of user´s response to Web based resources and its implications in improving lifestyle choices and promoting early screening & early detection of cancer.

Abstract
Background: Qiwam (Kimam) is a liquid tobacco preparation consumed with paan. It is mostly consumed in southeast Asian region. Evidences suggest that it causes potentially malignant disorders (PMD), oral cancer (OC) and decreases sperm count. Qiwam was mentioned in earlier research publications, however details are not known. It is produced for self-consumption as well as for commercial purpose. Aim: To study in detail the ingredients and processing steps involved in the production of Qiwam. In addition, also study the adverse health implication of this smokeless tobacco product on humans. Methods: The information on qiwam was collected via literature search study, study tour to different geographical areas of India, where group discussions with the people involved in the production of qiwam, paan vendors and with community members of different age group were done. Results: Qiwam is prepared by the user for his/her own consumption or by industry for sale. Tobacco leaves and tobacco roots are boiled for several hours then soaked in water flavored with varied spices and additives. The resultant mixture is mashed, strained, and finally dried into a thick paste. It is consumed mostly with paan. Conclusion: Processing of qiwam is a complex and time taking process which involves various steps and components that may influence the carcinogenic property of the product. The different processing steps gives different taste and texture to the product. Qiwam increases the risk of cancer and hence needs to be banned or better avoided.

Abstract
Background: Cancer is among leading cause of death (8.8 million) worldwide. Around 14.2 million new cases were recorded in 2012 and increasing each year. On the other hand there are about 2.8 billion users of different social media platforms (i.e., 37% of the world population). This tremendous power of social media can be used for disseminating effective information and communication on cancer prevention more efficiently (i.e., in less time to more people) to create awareness against the disease. Tobacco, alcohol and food industry have been using social media for aggressive advertising and marketing of their products. There is an urgent need to maximally use this medium of communication for advancing cancer prevention globally. Aim: To assess the role of social media in implementing effective health promotion strategies to advance cancer prevention. Methods: Extensive Web search has been done on the way social media (e.g., Facebook) is used for advancing public health communication and how it has been leveraged in the field of cancer prevention. Several Facebook pages and groups, YouTube channels were analyzed thoroughly. Various reports and articles on social media have been reviewed and analyzed. Results: Social media has been found very effective in terms of engaging greater number of population globally. Many Facebook pages and groups are available that provide information regarding specific cancer or provide support for cancer survivors. Several informative videos related to cancer prevention and survivors' stories are broadcast on various YouTube channels run by individuals, government, and nongovernment organizations. There have been many Instagram accounts on cancer but many of them don't provide relevant information on cancer prevention. However, genuine and relevant information are available through several Twitter handles. These social media platforms have very high penetration power. Facebook, YouTube, Instagram and Twitter have monthly reach to more than 1871, 1000, 500 and 263 million users respectively. This large number of user base can become a great source of spreading information on various aspects of cancer prevention through a comprehensive social media campaign. Conclusion: Social media platforms improve outreach and can also help carrying the relevant preventive health messages on cancer prevention, not only for the cancer patient but the public at large. Social media will help in amplifying the messages to the global mass while motivating prevention and health promotion to achieve public health objectives.

Abstract
Background: Global Adult Tobacco Survey (GATS-2) India (2016-17), reported that 5.1 crore rural women and 1.4 crore urban women use tobacco in any form. Cervical cancer is the second most common cancer in India among women accounting for 22.86% of all cancer cases in women and 12% of all cancer cases in both men and women. One woman dies of cervical cancer every 8 minutes in India. The risk of cervical intraepithelial neoplasia (CIN) was found to be increased with the women who smoke but the association between smokeless tobacco (SLT) and areca nut have not been adequately reported in the literature; hence this study was contemplated to bridge the literature gap. Aim: To find the association between SLT use and cervical premalignant and malignant lesions among those women screened for cervical cancer at Health Promotion Clinic. Methods: Retrospective analysis was performed on the electronically maintained records of the individuals screened for cervical cancer from February 2014 - February 2018 at the Health Promotion Clinic at National Institute of Cancer Prevention and Research (NICPR), Noida. All married women above 30 years of age were eligible to be screened for cervical cancer using visual inspection with acetic acid (VIA) and Papanicolaou (PAP) test, if any abnormality was found colposcopy was done, if required biopsy was performed for confirmation. The premalignant lesions were treated with thermocoagulation or loop electrosurgical excision procedure (LEEP) and those diagnosed of malignancy were referred to a tertiary care center for further treatment. The participant's data on sociodemographic status, tobacco use and results cervical cancer screening are maintained in an online electronic data capture system. Results: Out of 6538 individuals attended the Health Promotion Clinic, for their oral, breast and cervical cancer screening from February 2014 - February 2018, 5431 (83.1%) were females and 1107 (16.9%) were males. All the females with eligible criteria were screened for cervical cancer 5431. Among which 126 (2.3%) reported with the habit of smoking, 595 (11%) reported of SLT use and 52 (1%) reported of both smoking and SLT use. The SLT users were at a higher risk [odds ratio (OR)] of developing cervical lesions compared with the non-SLT users diagnosed by the PAP test 1.02 (1.020-1.028). Conclusion: Women consuming SLT are at high risk of developing cervical premalignant and malignant lesions compared with the non-SLT users.

Abstract
Background: The burden of cancers caused due to tobacco-related carcinogenic products is increasing at an alarming rate in India. Unlike the western world, where cancer-causing products are mostly smoked (such as cigarettes), in India it is mostly consumed as such without combustion. Such products are produced for self-consumption or for selling in the local markets within specific geographical locations. There is very little information available in the public search engines (PubMed) about such products (i.e., dohra [mixture of areca nut, catechu, edible lime, peppermint, cardamom, and some flavoring agents], tuibur [tobacco water sipped and retained in mouth for 5-10 minutes and then spit out], kaddipudi [fine powder of tobacco plant used as such, or in processed form, as bricks and blocks made with jaggery and water], and hogesoppu [tobacco leaf used by women either as such or with betel]). Aim: To study the (i) geographical distribution, (ii) varieties, (iii) production and (iv) adverse health effects of unbranded chewable or drinkable carcinogenic products from India. Methods: The information on unbranded carcinogenic products was collected via study tour to different geographical areas of India, via group discussions or telephonic talks with community members of different age groups. Results: Dohra is found in the state of Uttar Pradesh, India. It majorly contains areca nut which contains a carcinogenic compound - arecoline known for causing histologic changes in the oral mucosa. Tuibur is found in the state of Manipur and Mizoram. Evidence suggests that it contains tobacco which is rich in N-nitroso compounds known for causing systemic tumors. Kaddipudi and hogesoppu are found in the state of Karnataka. Both of them contain tobacco. Conclusion: Dohra, Tuibur, kaddipudi and hogesoppu are unbranded cancer-causing products used at specific geographical locations in India. Since these products contain carcinogenic compounds, their use should be avoided.

Abstract
Background: India is facing noncommunicable diseases epidemic with cancer as one of the main reasons of mortality. To bring this epidemic under control and as a measure of secondary prevention, government of India has rolled out operational framework for population cancer screening. As cancer screening is a new concept for Indian health care providers, this study focuses on the attitudes and perceptions of HCP from a district in Assam. Aim: To know the attitudes and perceptions of healthcare providers in Assam about the implementation of population based cancer screening program in India. Methods: This study was a part of ongoing Indian Council of Medical Research project at Cachar district, Assam. The study was conducted at Silchar, Assam and the study participants were attendees of the master trainers' workshop which was conducted for the pilot cancer screening program rolled out in Cachar district, Assam. Self-administered questionnaires were used to collect data from the health care providers on the last day of the training. Data were gathered from 58 participants. The participants were medical officers, auxillary nurse midwives (ANM), accredited social health activists (ASHA), staff nurses, nongovernmental organization (NGO) representatives and other health care providers from public health facilities. Results: Majority of the study participants agreed with the concept of screening. Half of the study participants stated that they could conduct screening comfortably along with their other responsibilities. Lack of human resources and an overburdened human resource were the main challenges foreseen in the implementation of the program. 91% of the participants wanted GOI to implement the cancer screening program. Majority of the health personnel were in favor of primary health center (PHC) as the first preferable site of population cancer screening followed by subcenter being second on preference for screening. One-third of study participants opined that screening should be done by specialist doctors. Almost one fifth of participants stated that ASHA should do the screening and almost same number of participants thought that medical officer at PHC should do the screening. Conclusion: This is the first pilot study on the population based cancer screening guidelines released by the government of India. The organized screening program is yet to be rolled out in the country. Though many challenges were foreseen by the healthcare providers in carrying out the population based cancer screening, majority were optimistic for the implementation of this screening program.

Abstract
Background and context: Cancers of the breast, uterine cervix, and oral cavity are the 3 most common malignancies in India. Overall, they comprise around one third of >1 million cases diagnosed with cancer in India each year. An effective operational framework (OF) for early detection and screening programs should play a key role in reducing and managing the cancer burden in India. Aim: i. To provide guidelines to the clinicians, and public health practitioners for screening and early detection of breast, uterine cervix, and lip or oral cavity cancers in India. ii. To build guide/roadmap for policymakers involved in developing and implementing strategies for cancer control in India. Strategy/Tactics: In collaboration with the Center for Global Health at the U.S. National Cancer Institute, 25 scientific experts comprising researchers, public health leaders, medical and dental professionals from France, India, United States, and Zambia met at Indian Council of Medical Research (ICMR)-National Institute of Cancer Prevention and Research, to summarize the feasible options and relevant evidence for screening and early detection of common cancers in India. They came out with the operational framework Program/Policy process: Recognizing the key role that effective early detection and screening programs could have in reducing the cancer burden, the ICMR-National Institute of Cancer Prevention and Research, in collaboration with the U.S. National Cancer Institute Center for Global Health, held a workshop to summarize feasible options and relevant evidence for screening and early detection of common cancers in India. Outcomes: a. A publication in Lancet: Rajaraman P, Anderson BO, Basu P, et al: Recommendations for screening and early detection of common cancers in India. Lancet Oncol 16(7):e352-e361, 2015. b. State and PHC level trainings on operational framework started in each state for the primary health care providers. What was learned: The OF acts as a guide for policymakers, clinicians, and public health practitioners who are developing and implementing strategies in cancer control. Common and consistent OF will go a long way to chart out the intensity of the problem and to rectify it.

Abstract
Introduction: Kiwam (qiwam) is a partially fermented tobacco product consumed with betel quid (paan). The major constituents of this product are tobacco, saffron (zaffrani) and some other additives. It contains tobacco-specific nitrosamines (TSNA) which is considered as a cancer causing agent. To elucidate the carcinogenic property of kiwam, biochemical profiling of its constituents at different stages of processing is needed. The major processing steps involved in the formation of kiwam and biochemical profiling/changes at each processing step is still unknown. Aim: To describe the major processing steps and biochemical changes that occur at each processing step during the preparation of kiwam. Methods: Tobacco leaves and stems were washed with Millipore water so as to remove the dirt particles from the leaves and stems. It is then boiled in water followed by filtering of the constituents to remove the leaves and stem residues. The filtrate was again boiled to form a thick paste residue. The resultant paste was partially fermented through sun curing, and lastly, saffron along with specific additives was added. The samples from each step were analyzed for biochemical profiling through Continuous Flow Autoanalyzer using Flow View Solution 3700 Analyzer (version 1.2.2) software. Results: The biochemical changes at TSNA levels were observed at each processing steps. The detailed chemical profiling will be presented during the meeting. Conclusion: Kiwam is rich in TSNA and hence its use should be avoided.

Abstract
Background: Oral cancer is the third most common cancer in India which is attributed to the high tobacco burden especially due to a myriad of smokeless tobacco (SLT) products available in the market. Gul/Gul manjan is a commercially-produced, tobacco-based dentifrice, indigenous to rural India and Bangladesh, and mainly used by women. It is both highly addictive and carcinogenic; yet its prevalence, reasons for use and association with oral potentially malignant disorders (OPMDs) and oral cancer are scarcely documented in literature, making this study the first of its kind. Aim: To determine the prevalence of Gul use, its predictors and resultant OPMDs and oral cancer in such consumers. Methods: A cross-sectional study was performed among 3452 individuals visiting the Institute's Oral Health Promotion Clinic between December 2016-March 2018. Their basic demographic details, tobacco use history and abnormalities found on oral examination, were documented in the clinical record form. Data pertaining to Gul users was subjected to further statistical analysis. Results: Of the total individuals screened, 2.9% (n=101, P < 0.001) consumed Gul (89.1% current and 10.9% former users), with majority female consumers (86.1%) from peri-urban Noida. It was used (up to 5 times daily) mainly to alleviate dental pain due to caries/endodontic lesions, which were present in 35.6% users ( P = 0.004). A statistically significant positive association was seen between Gul use and development of OPMDs ( P < 0.001) and oral cancer ( P = 0.001), with 7.9% (n=10; 70% Gul alone users) of the overall leukoplakias/preleukoplakias (n=127), and 7.1% (n=1, Gul alone user) of all the oral cancer cases (n=14), found in Gul users. The duration of Gul use ranged up to 25 years, indicating its high dependency. Conclusion: Gul use is relatively uncommon than other SLT products in India, even among males (the major group of tobacco consumers). Apart from teeth cleaning, Gul is a cheap, easily accessible antidote for acute dental pain relief (owing to nicotine-induced analgesia) among rural women who apply it multiple times daily onto the affected teeth and adjacent gum/mucosa, often leading to its dependency. Courtesy its significant carcinogenic potential which has been clearly reported here (OPMDs and oral cancer development among users), combating/preventing its production, easy availability (in spite of the complete ban on tobacco use in dentifrices) and consumption, is essential. Therefore, the public health challenge of prevention of the use of this form of SLT ie tobacco-based dentifrices, warrants greater interest and action than that has been received thus far, which in turn would contribute to the overall mission of oral cancer prevention.

Abstract
Background and context: Three most common cancers in India are breast, uterine cervix and oral cavity, together accounting for approximately 34% of all cancers. Ministry of Health and Family Welfare, India has released an operational guidelines for cancer screening last year and has urged all the states to roll out population based cancer screening at various health care levels. As per these guidelines, the existing health care providers (HCPs) at various facilities would be rolling out the population based cancer screening in the country. However, the existing HCPs lack the skills and are not trained in cancer screening. Considering the size of the country, it is neither a feasible nor economically viable to provide in-person training for all cadres of HCPs. The limitation is comprehensively overcome by ECHO (Extension for Community Healthcare Outcomes) model provides a cost effective way to exponentially expand the capacity to mentor and train these HCPs in cancer screening best practices. ECHO as per the motto to “move knowledge rather than patients or doctors”, uses widely available one to many video-conferencing technology, didactic presentations and case based learning techniques to mentor and support HCPs to implement best practices in the field. In teleECHO clinics expert teams at an academic “hub” partner with willing participants to participate in knowledge networks in which all teach and all learn. Aim: To train the health care providers in cancer screening through technology assisted learning. Strategy/Tactics: A structured training program was designed using ECHO platform for all HCPs in separate batches that included, gynecologists, dentists and community health workers (CHWs), by virtual training to address all issues while they roll out cancer screening in their communities. Program/Policy process: A structured course of 20 week-sessions' virtual (online) cancer screening training program for various cadres of health care providers was undertaken. A typical one hour of ECHO session consisted of 25-30 minutes of didactics by the expert followed by 2 case presentations by the spokes. A “Beginner´s program” was well received by the participants who requested us to take it ahead with “Advanced training program” for specialists. Outcomes: 58 participants completed the course in cancer screening. The pre- and posttraining knowledge evaluation demonstrated a significant increase in the knowledge gained by participants. What was learned: In a resource constrained environment it is feasible to develop a basic curriculum in cancer screening program and train and support, all cadres of HCPs. Rolling out a technology enabled model such as ECHO for teaching and training can enable the development of a population based cancer screening program.

Abstract
Background: Smokeless tobacco (SLT) is available in many forms in India and is widely used by all social groups. SLT market in India is the world largest market. Over the last 2 decades, the SLT industry in India has grown immensely, mostly in cottage industry sector and unorganized sector. Several SLT products are self-made or mixed by users themselves. This presents a great challenge for regulation of such unbranded and loose products. Cancer of the oral cavity and the pharynx are a major public health problem in India. At least 90% of these cancers are caused by SLT products use. Aim: To study the challenges for unbranded SLT products in implementing the mandated regulatory compliances under the Indian Tobacco Control Law that applies to all tobacco products. Methods: The information on unbranded/loose SLT products was collected through literature search, field trips, discussions with SLT product vendors and with community members of different age group. Results: Several types of unbranded SLT products are sold both in urban and rural India. These unbranded products vary from state to state. In some cases they vary from 1 place to another within a state. Most of the unbranded products do not comply with the legal mandates of the Indian tobacco control (COTPA) and food safety (FSSA) laws that regulate sale of tobacco products. The biggest fall-out of unbranded sale is that there is no pictorial health warnings to warn the users about the ill effects of these SLT products as required under section 7 of COTPA. In addition these products also do not mention the minimum requirement of the packaging and labeling under the legal metrology law. In absence of the pictorial health warnings these SLT products become more accessible and affordable to minors. The FSSA prohibits use of tobacco and nicotine as ingredient in any food item, however, most of the unbranded SLT products are sold with added flavorings, condiments and spices which are classified as food. Conclusion: Strict implementation of the mandated regulatory provisions is needed to check the unrestricted sale of unbranded products. Noncompliant unbranded/loose SLT products should be confiscated as per the prescriptions of the existing tobacco control and food safety laws. Findings from this paper calls for development of policies that will prevent sale of unbranded/loose SLT products in India to protect the unsuspecting youth and other vulnerable group of population from these cancer traps.
