Rapid ecosystem service assessment of a protected wetland in Myanmar, and implications for policy development and management

Many of the world's wetlands have been degraded or destroyed, with Asia being one of the most impacted regions globally. Given the likelihood that Myanmar will increase rice production in the coming years, we assessed the impact of this on the Moeyungyi Wetland Wildlife Sanctuary in Myanmar, and the ecosystem services it provides. Using a framework outlined in the Toolkit for Ecosystem Service Site-based Assessment (TESSA), we estimated that sanctuary provides annual benefits of at least $22 million y -1 ($2130 ha −1 y -1; 2014 US dollars) and that these benefits are received by local communities (c.12,000 households), downstream rice farms, and the international communities. We show that an increase in water use for increasing rice production in nearby town was not considered to have a significant effect on the benefits that the wetland currently provides. However, our results are subject to methodological assumptions and limitations. Notwithstanding this, we found TESSA to be useful for providing information to local and national stakeholders on the broader importance of the conservation of wetlands. Our case study demonstrates how rapid ecosystem service assessments may pave the way to sustainable management of Myanmar's wetlands. </p

Natural history of non-functioning pituitary microadenomas - results from the UK NFPA consortium.

OBJECTIVE: The optimal approach to the surveillance of non-functioning pituitary microadenomas (micro-NFPAs) is not clearly established. Our aim was to generate evidence on the natural history of micro-NFPAs to support patient care. DESIGN: Multi-centre, retrospective, cohort study involving 23 endocrine departments (UK NFPA consortium). METHODS: Clinical, imaging, and hormonal data of micro-NFPA cases between 1/1/2008 and 21/12/2021 were analysed. RESULTS: Data for 459 patients were retrieved [median age at detection 44 years [interquartile range (IQR) 31-57) - 152 males/307 females]. 419 patients had more than two MRIs [median imaging monitoring 3.5 years (IQR 1.71-6.1)]. One case developed apoplexy. Cumulative probability of micro-NFPA growth was 7.8% (95%CI 4.9%-8.1%) and 14.5% (95%CI 10.2%-18.8%) at 3 and 5 years, respectively, and of reduction 14.1% (95%CI 10.4-17.8%) and 21.3% (95%CI 16.4-26.2%) at 3 and 5 years, respectively. Median tumour enlargement was 2 mm (IQR 1-3) and 49% of micro-NFPAs that grew became macroadenomas (nearly all >5 mm at detection). Eight (1.9%) patients received surgery (only one had visual compromise with surgery required >3 years after micro-NFPA detection). Sex, age, size at baseline were not predictors of enlargement/reduction. At time of detection, 7.2%, 1.7% and 1.5% patients had secondary hypogonadism, hypothyroidism and hypoadrenalism, respectively. Two (0.6%) developed hypopituitarism during follow-up (after progression to macroadenoma). CONCLUSIONS: Probability of micro-NFPA growth is low and development of new hypopituitarism is rare. Delaying first follow-up MRI to three years and avoiding hormonal re-evaluation in absence of tumour growth or clinical manifestations is a safe approach for micro-NFPA surveillance

RESULTS: Data for 459 patients were retrieved [median age at detection 44 years (IQR 31-57)-152 males/307 females]. Four hundred and nineteen patients had more than two magnetic resonance imagings (MRIs) [median imaging monitoring 3.5 years (IQR 1.71-6.1)]. One case developed apoplexy.
