Targeted preventive therapy for individuals at highest risk of incident tuberculosis might impact the epidemic by interrupting transmission. We tested performance of a transcriptomic signature of tuberculosis (RISK11) and efficacy of signature-guided preventive therapy in parallel, using a hybrid three-group study design. Adult volunteers aged 18–59 years were recruited at five geographically distinct communities in South Africa. Whole blood was sampled for RISK11 by quantitative RT-PCR assay from eligible volunteers without HIV, recent previous tuberculosis (ie, <3 years before screening), or comorbidities at screening. RISK11-positive participants were block randomised (1:2; block size 15) to once-weekly, directly-observed, open-label isoniazid and rifapentine for 12 weeks (ie, RISK11 positive and 3HP positive), or no treatment (ie, RISK11 positive and 3HP negative). A subset of eligible RISK11-negative volunteers were randomly assigned to no treatment (ie, RISK11 negative and 3HP negative). Diagnostic discrimination of prevalent tuberculosis was tested in all participants at baseline. Thereafter, prognostic discrimination of incident tuberculosis was tested in the untreated RISK11-positive versus RISK11-negative groups, and treatment efficacy in the 3HP-treated versus untreated RISK11-positive groups, during active surveillance through 15 months. The primary endpoint was microbiologically confirmed pulmonary tuberculosis. The primary outcome measures were risk ratio [RR] for tuberculosis of RISK11-positive to RISK11-negative participants, and treatment efficacy. This trial is registered with ClinicalTrials.gov, NCT02735590. 20 207 volunteers were screened, and 2923 participants were enrolled, including RISK11-positive participants randomly assigned to 3HP (n=375) or no 3HP (n=764), and 1784 RISK11-negative participants. Cumulative probability of prevalent or incident tuberculosis disease was 0·066 (95% CI 0·049 to 0·084) in RISK11-positive (3HP negative) participants and 0·018 (0·011 to 0·025) in RISK11-negative participants (RR 3·69, 95% CI 2·25–6·05) over 15 months. Tuberculosis prevalence was 47 (4·1%) of 1139 versus 14 (0·78%) of 1984 in RISK11-positive compared with RISK11-negative participants, respectively (diagnostic RR 5·13, 95% CI 2·93 to 9·43). Tuberculosis incidence over 15 months was 2·09 (95% CI 0·97 to 3·19) vs 0·80 (0·30 to 1·30) per 100 person years in RISK11-positive (3HP-negative) participants compared with RISK11-negative participants (cumulative incidence ratio 2·6, 95% CI 1·2 to 5·9). Serious adverse events related to 3HP included one hospitalisation for seizures (unintentional isoniazid overdose) and one death of unknown cause (possibly temporally related). Tuberculosis incidence over 15 months was 1·94 (95% CI 0·35 to 3·50) versus 2·09 (95% CI 0·97 to 3·19) per 100 person-years in 3HP-treated RISK11-positive participants compared with untreated RISK11-positive participants (efficacy 7·0%, 95% CI −145 to 65). The RISK11 signature discriminated between individuals with prevalent tuberculosis, or progression to incident tuberculosis, and individuals who remained healthy, but provision of 3HP to signature-positive individuals after exclusion of baseline disease did not reduce progression to tuberculosis over 15 months.

Purpose To explore nurses’ perceptions of the organizational climate in general hospitals in Myanmar. Design and Methods Using a qualitative descriptive design, data were purposively collected from all levels of registered nurses in eight general hospitals across Myanmar during August to October 2019. Seventeen individual in‐depth interviews and eight focus group discussions with 65 nurses were undertaken and analyzed using Graneheim and Lundman’s qualitative content analysis. Findings Four categories of organizational climate from a Myanmar nursing context emerged: organizational uniqueness, organizational alignment, sense of empowerment, and the reinforcing organization. Organizational uniqueness included the subcategories of perception of features and orientation of the organization, whilst organizational alignment comprised the three subcategories of the values inherent in the management process, the criteria of success, and strategic emphasis. The sense of empowerment category embraced the subcategories of the perceptions of the decision making and roles of leaders or managers; the last category, the reinforcing organization, incorporated the subcategories of bonding and recognition of the organization. Conclusions This was the first qualitative nursing study on nurses’ perceptions of organizational climate in Myanmar hospitals. Participants revealed a rich source of information that needs to be considered by hospital administrators and other policymakers to enhance quality clinical care by nurses, and their overall well‐being and working conditions. The emphasis on the holistic nature of this concept points to further investigations of working conditions, the lives of nurses, and management of nurses within the hospital environments in Myanmar hospitals, and can inform other countries. Clinical Relevance Nurses revealed a rich understanding of what an organizational climate represents or should represent, and they need to work with hospital administrators and managers to contribute to the development of positive organizational climate, which in turn should increase nurse retention and the efficacy of health care provided in hospitals.

The endemic roofed turtle Kachuga trivittata has been extirpated over most of its former range in the Ayeyarwady River system of Myanmar. Only two small remnant populations are known to survive. In a small stretch of the upper Chindwin River K. trivittata persists because local Shan villages traditionally ban the killing of large adult K. trivittata. The population has nevertheless declined dramatically during the last few years because of the erosion of the ban by migrant fishermen from central Myanmar who do not observe the local regulation, and because of the overexploitation of eggs. The traditional regulation of the Shan villages offers a basis, through its reinforcement and education of migrants, for a species recovery programme. Further actions will include the protection of nests and eggs, and eventually the banning of camps and seasonal settlements on sandbanks used by K. trivittata for nesting. K. trivittata also still persists in the Dokhtawady River in a small area subjected to low exploitation pressure in the recent past because of the dangers of a frontline between the government army and an army of insurgents. The opening of this area following a truce brought this population close to extinction and a hydroelectric dam under construction will alter the ecology of this stretch of river. We propose to assess the potential use of the future impoundment lake for the recovery of this K. trivittata population.
