Abstract
'Digital Mega-Studies' are entirely or extensively digitised, longitudinal, population-scale initiatives, collecting, storing, and making available individual-level research data of different types and from multiple sources, shaped by technological developments and unforeseeable risks over time. The Australian 'Gen V' project exemplifies this new research paradigm. In 2019, we undertook a multidisciplinary, multi-stakeholder process to map Digital Mega-Studies' key characteristics, legal and governance challenges and likely solutions. We conducted large and small group processes within a one-day symposium and directed online synthesis and group prioritisation over subsequent weeks. We present our methods (including elicitation, affinity mapping and prioritisation processes) and findings, proposing six priority governance principles across three areas-data, participation, trust-to support future high-quality, large-scale digital research in health.

Abstract
Population-based genetic analyses, such as the Genome-Wide Association Study (GWAS), have proven powerful for describing the genetic complexities of common disease in epidemiologic research. However, the significant challenges faced by population-based study designs have resulted in revitalization of family-based approaches, including twin studies. Twin studies are unique in their ability to ascertain both heritable and environmental contributions to human disease. Several regional and national twin registries have been constructed using a variety of methods to identify potential twins. A significant challenge in constructing these large twin registries includes the substantial resources required to recruit participants, collect phenotypic data, and update the registries as time progresses. Here we describe the use of the Marshfield Clinic electronic medical record (EMR) to identify a cohort of 19,226 patients enriched for twins or multiples. This cohort defines the Marshfield Clinic Twin/Multiple Birth Cohort (MCTC). An EMR system provides both a mechanism to identify potential twins and a source of detailed phenotypic data in near real time without the need for patient contact outside standard medical care. To demonstrate that the MCTC can be used for genetic-based epidemiologic research, concordance rates for muscular dystrophy (MD) and fragile-X syndrome-two highly heritable diseases-were assessed. Observations indicate that both MD and fragile-X syndrome are highly correlated among affected twins in the MCTC (P ≅ 3.7 × 10(-6) and 1.1 × 10(-4) , respectively). These findings suggest that EMR systems may not only be an effective resource for predicting families of twins, but can also be rapidly applied to epidemiologic research.

Abstract
BACKGROUND Medically unexplained symptoms (MUS) are common in primary care across cultures, accounting for high consultations with multiple providers and unnecessary investigations. Cognitive behavioural therapy (CBT) is efficacious for MUS and reduces physical symptoms, psychological distress and disability. Two intervention trials by the author and his group remain the only reported trials from the developing world. MATERIAL A treatment package was designed by modifying a CBT model. The modifications were innovative use of locally relevant appropriate language and strategies that were simple enough while conforming to the CBT principles. The aim was to convey the principles of CBT to people using simple techniques--using metaphor. These are described in the paper as generic metaphors that could be used to explain the CBT principles and specific ones for patients with MUS. DISCUSSION Metaphor is an effective clinical tool. The author's clinical experience and patients' feedback suggest that these metaphors are helpful in conveying the CBT principles to patients. To develop metaphors appealing to the client and effective clinically, carrying out qualitative research among patients' explanatory model is an important prerequisite. The generic and MUS-specific metaphors reported here should be tried in other cultural and clinical settings and evaluated. Further systematic work including qualitative work for consensus evaluation among CBT experts as well as opinion on user-friendliness of these techniques tested among CBT practitioners will be needed.

Abstract
The Sri Lankan Twin Registry (SLTR), established in 1997, is a unique resource for twin and genetic research in a low- and middle-income country (LMIC). It comprises of a volunteer cohort of 14,120 twins (7,060 pairs) and 119 sets of triplets, and a population-based cohort of 19,040 (9,520 pairs) twins and 89 sets of triplets. Several studies have been conducted using this registry, including the Colombo Twin and Singleton Study (CoTaSS 1; 4,387 twins, 2,311 singletons), which have explored the prevalence and heritability of a range of psychiatric disorders as well as gene-environmental interplay. Currently, a follow-up study (CoTaSS 2) of the same cohort is underway, looking at the prevalence and interrelationship of key cardiovascular and metabolic risk markers (e.g., metabolic syndrome). A significant feature of CoTaSS 2 is the establishment of a biobank. Current SLTR work is extending beyond mental health and the interface between mental and physical health to new horizons, extending collaborations with the wider global twin research community. Ethics and governance have been given special emphasis in the initiative. Capacity building and public engagement are two crucial components. Establishment of a state-of-the-art genetic laboratory was a major accomplishment. SLTR is a classic showcase of successful North-South partnership in building a progressive research infrastructure in a LMIC.

Abstract
AbstractWe report the process of adaptation into Sinhala of a questionnaire given to mothers of twins to determine zygosity. Adaptation and validation was carried out in three stages. Firstly, we used a nominal group to translate the English version and to assess the extent of agreement (consensus measurement) on the appropriateness of the translation and resolve disagreement (consensus development). Secondly we used a qualitative interview with 25 mothers of twins. The three main stems of the translated questionnaire were used as a semi-structured interview, and the responses noted verbatim. These were categorised and analysed, and the translated full questionnaire was then presented as closed questions with fixed choice responses. The categorised responses generated during the qualitative interview were compared with the responses to the fixed choices in the full questionnaire. The third stage was the appraisal of the questionnaire by 17 bilingual parents of twins. The source and translated version of the questionnaire were given to them at least 3 days apart. The responses were rated and the total scores were computed to determine the zygosity. This step was carried out to measure the validity and reliability of the Sinhala version. A perfect correlation between the original and adapted version was obtained, with a kappa of 1. The results suggest that the Sinhala version of the questionnaire is conceptually equivalent to the original questionnaire. Comparison of the zygosity determination by using this adapted questionnaire with results from analysis of genetic markers on Sri Lankan twins is needed for final validation of the translated questionnaire.

Abstract
There is an enormous inequity in global health as well as research. Less than 10% of research funds are spent on the diseases that account for 90% of the global disease burden. This case study of north-south, south-south collaborations in Sri Lanka is a classic example of the issues faced by mental health researchers in low and middle income countries (LMICs). In this paper, work carried out by the Institute of Psychiatry (IoP), King's College London and the Institute for Research and Development (IRD) partnership since 1997 in Sri Lanka is presented to show an example of a successful private research institution based in a LMIC as a product of south-south and north-south collaboration in mental health research. The evidence of scarcity of mental health research and resources is overwhelmingly abundant in the context of Sri Lanka. IRD-IoP partnership showcases a successful north-south partnership with equality and efficiency. It has moved beyond start-up phase and has become a sustainable initiative in terms of funding, collaboration, research output and policy impact. International funding agencies, academics, and other bodies need to address sustaining such initiatives as priorities in reducing scarcity and inequity in mental health research in developing countries.

Abstract
The Sri Lankan Twin Registry began as a volunteer register in 1997. Previously, we have shown door-to-door surveys as the best option to build a population-based twin register of older, adult twins. Our aim was to build a population-based twin register in the Colombo district and use it for twin studies on common mental disorders. We aimed to identify a random sample of 4000 twins ascertained through the twin census. The Colombo district is divided into 13 divisional secretariat divisions (DSDs) and each division is further divided into Grama Niladari divisions administratively. Grama niladaris (GNs) are civil servants and visit each household in order to update the electoral register. GNs were used to do a census of twins while they updated the electoral register. The correlation between population density and twin rate among DSDs was .81, and between twin rate and the percentage of returned forms (from each DSD) was .74. We received 9648 forms notifying about twins and multiples. After removing the duplicates and information about twins who live in other districts, there were 17,406 multiples remaining. After incorporating twins and multiples from various other feasibility studies we now have 19,040 multiples with 8.46 twins per 1000 people in the Colombo district.

Abstract
To date, relatively little is known about the ethical, legal and social responses to recent advances in reproductive and genetic technology outside Europe and North America. This article reports on a survey carried out among doctors (n=278) and medical students (n=1256) in Sri Lanka to find out more about their responses to novel interventions in human reproduction such as In-Vitro Fertilization, Pre-Implantation Genetic Diagnosis and genetic engineering. In the first part of the paper comparisons are drawn between this survey and a survey carried out in 1985 which also considered issues surrounding amniocentesis and therapeutic termination. The second part of the paper deals with more recent developments. The analysis reveals high levels of support for the use of new technologies in treating infertility and identifying genetic disorders. However, differences are apparent among the major religious communities represented in the sample and these are particularly in evidence in relation to prenatal genetic diagnosis. An important theme throughout both surveys is the continuing tension surrounding State policy and termination of pregnancy and the implications this has for the development of screening and counseling services where genetic disorders are concerned.

Abstract
BACKGROUND Establishment of Sri Lankan Twin Registry demanded development of ethical guidelines, as an effective ethical framework was not available in Sri Lanka. DESIGN Objectives were to find out whether the ombudsman concept exists in current informed consent practices and to investigate opinion about ombudsmen. We searched Pub Med, conducted a postal survey, and monitored Internet discussion. RESULTS The responses were categorized into current practices and existing models in informed consent process, reservations expressed about current practices, arguments supporting the concept, concerns and issues, alternatives, and how to implement the proposal. The concept of a third person is not entirely novel. How to find a truly independent person, the financial implication, confidentiality, obligations, and liabilities of ombudsmen, also emerged. CONCLUSIONS The concept of an ombudsman is conceptually and ethically sound and acceptable but the challenges posed by this very same solution to creating a better process of informed consent will have to be faced.

Abstract
Sri Lanka is an island situated close to the southern tip of the Indian subcontinent with a land area of about 65 000 km2. The population in 2001 was 18.5 million. It has an interesting genetic diversity, its five main populations revealing both European and Asian origins. Although Sri Lanka is a developing country, it has strengths that other developing countries do not have, mainly in health and education. However, Sri Lanka lacks a research culture and has inadequacies in its research capabilities; hence, capacity building is essential. Based on our research findings, we plan to achieve this by working with professionals, statutory services, policy-makers and the public. Our model is international collaboration based on our own research agenda. Such partnerships can produce high-quality research, with greater influence on national policy and practice (Costello & Zumla, 2000).
