IntroductionIn low-income and middle-income countries, people with spinal cord injury (SCI) are vulnerable to life-threatening complications after they are discharged from hospital. The aim of this trial is to determine the effectiveness and cost-effectiveness of an inexpensive and sustainable model of community-based care designed to prevent and manage complications in people with SCI in Bangladesh.Methods and analysisA pragmatic randomised controlled trial will be undertaken. 410 wheelchair-dependent people with recent SCI will be randomised to Intervention and Control groups shortly after discharge from hospital. Participants in the Intervention group will receive regular telephone-based care and three home visits from a health professional over the 2 years after discharge. Participants in the Control group will receive standard care, which does not involve regular contact with health professionals. The primary outcome is all-cause mortality at 2 years. Recruitment started on 12 July 2015 and the trial is expected to take 5 years to complete.Ethics and disseminationEthical approval was obtained from the Institutional Ethics Committee at the site in Bangladesh and from the University of Sydney, Australia. The study will be conducted in compliance with all stipulations of its protocol, the conditions of ethics committee approval, the NHMRC National Statement on Ethical Conduct in Human Research (2007), the Note for Guidance on Good Clinical Practice (CPMP/ICH-135/95) and the Bangladesh Guidance on Clinical Trial Inspection (2011). The results of the trial will be disseminated through publications in peer-reviewed scientific journals and presentations at scientific conferences.Trial registration numbersACTRN12615000630516, U1111-1171-1876.

Study design Cross-sectional analysis of a mixed retrospective and prospective inception cohort study. Objectives To determine health status, quality of life and socioeconomic situation of people with spinal cord injuries (SCI) 6 years after discharge from a hospital in Bangladesh. Setting Bangladesh. Methods All patients alive 6 years after discharge from a hospital in Bangladesh were interviewed using the SF12 health survey, the SCI Secondary Conditions Scale, the Centre for Epidemiologic Studies Depression Scale (CESD), and the participation in society items of World Health Organisation Disability Assessment Schedule (WHODAS 2.0). Additional questions determined participants' socioeconomic and employment status. Results The cohort comprised 260 participants: 145 used wheelchairs for mobility and 115 were able to walk at discharge. The median (IQR) Mental and Physical Component scores for the SF12 were 54 (49-57) and 44 (40-51) points, respectively. The median scores for the SCI Secondary Conditions Scale, CESD and WHODAS 2.0 were 8 (4-13), 7 (4-13) and 12 (6-17) points, respectively. Fourteen percent of all participants and 23% of those who used wheelchairs had a pressure ulcer at the time of interview. Forty-four percent of participants were unemployed and 65% were living below the poverty line (median (IQR) income, USD 0 (0-91)) per month. Conclusion Many people with SCI in Bangladesh are unemployed and living in poverty with a reduced quality of life and participation. Pressure ulcers are a common complication.

To assess the efficiency of genetic improvement programs, it is essential to assess the genetic trend in long-term data. The present study estimates the genetic trends for grain yield of rice varieties released between 1970 and 2020 by the Bangladesh Rice Research Institute. The yield of the varieties was assessed from 2001–2002 to 2020–2021 in multi-locations trials. In such a series of trials, yield may increase over time due to (i) genetic improvement (genetic trend) and (ii) improved management or favorable climate change (agronomic/non-genetic trend). In both the winter and monsoon seasons, we observed positive genetic and non-genetic trends. The annual genetic trend for grain yield in both winter and monsoon rice varieties was 0.01 t ha−1, while the non-genetic trend for both seasons was 0.02 t ha−1, corresponding to yearly genetic gains of 0.28% and 0.18% in winter and monsoon seasons, respectively. The overall percentage yield change from 1970 until 2020 for winter rice was 40.96%, of which 13.91% was genetic trend and 27.05% was non-genetic. For the monsoon season, the overall percentage change from 1973 until 2020 was 38.39%, of which genetic and non-genetic increases were 8.36% and 30.03%, respectively. Overall, the contribution of non-genetic trend is larger than genetic trend both for winter and monsoon seasons. These results suggest that limited progress has been made in improving yield in Bangladeshi rice breeding programs over the last 50 years. Breeding programs need to be modernized to deliver sufficient genetic gains in the future to sustain Bangladeshi food security.
