Belt and road initiative and healthy silk road:an alternative path for Pacific island countries to participate in global public health governance

Pacific island countries(PICs)located in a region with relatively insufficient capacity to respond to public health emergencies,establishing reliable public health cooperation is conducive to maintaining security and stability.The belt and road initiative(BRI)launched by China attempts to provide a novel form of international cooperation and has supported multi-channel investment and construction.This article elucidates the history of public health cooperation between China and PICs,as well as the current situation of the BRI in the field of public health and emphasizes that there are numerous constraints in the public health cooperation between China and PICs.Given the profound impact of COVID-19 on diplomatic strategies,gradual cooperation in the field of public health may be the initial exploration of the BRI in the PICs,but it also means that the initiative must deal with challenges from geopolitical competition and cultural differences.

Demographic features and visual outcomes of patients presenting to diabetic photo-screening and treated for sight threatening retinopathy in Fiji

AIM：To describe the demographic features and visual outcomes of patients presenting to photo-screening services, and treated for sight threatening retinopathy（STR） in a low resource setting, Fiji.METHODS：A retrospective review of all new patients who presented for diabetic photo-screening at the Diabetic Eye Clinic, Suva in 2010. Fundus images were graded using standardised guidelines. Patient demographics, retinopathy grading and visual acuity data were extracted from the database and analyzed. Patients that received laser therapy and still attending follow up in 2012 were examined for disease progressionRESULTS：Totally 2236 patients were photo-screened, 87%（3870/4472） of images were gradable. STR was observed in 26%（988/3870） with advanced STR（proliferative retinopathy/severe maculopathy） in 10%（385/3870）. Of those with STR, 59% had BCVA ≥6/18, 31% with advanced STR were 〈6/60. Male gender [odds ratio（OR） 1.59; 1.20-2.12], history of hypertension（OR 1.36; 1.03-1.80） and peripheral neuropathy（OR 1.41; 1.01-1.95） were predictive of advanced STR. In 2012, 32%（315/988） attended follow up with 69% exhibiting advanced STR compared with 53% of the same cohort in 2010. Laser photocoagulation was administered to 212 eyes（212/3870, 5%） with retinopathy and maculopathy progression observed in 52% and 33% respectively. BCVA ≥6/18 was noted in 67%（143/212） of treated eyes. Improved glycaemic control（OR 46.52; 1.50-1441.90） amongst those with advanced STR was predictive of eyes that maintained good vision.CONCLUSION：In Fiji, a quarter of new patients presenting to photo-screening have STR with a third of those with advanced STR having already loss vision. Improved glycaemic control and timely treatment of patients with sight threatening complications is important in halting disease progression.

Recent emergence and outbreak of rotavirus gastroenteritis in Samoa:A scoping review of risk factors,containment measures and public health preparedness

Diarrheal diseases have been known to cause death in many children below the age of five years,and rotavirus infection represents a major health problem in the world today,particularly in developing countries.The recent outbreak of rotavirus gastroenteritis in Samoa led to the introduction of her debut national immunization program on rotavirus vaccination for infants.Despite the introduction of anti-viral and anti-emetic drugs as of the containment approaches towards the virus,risk factors,preventive measures and public health preparedness against rotavirus infection are poorly understood in Samoa.This review aims to use available evidence on rotavirus literature to elucidate and map preventive strategies for the recently emerged rotavirus infections in Samoa.We conducted a search strategy using online medical literature databases and retrieval systems.A designated set of keywords such as rotavirus,gastroenteritis,outbreak,risk factors,containment measures,vaccination and Samoa were inserted in electronic databases to retrieve articles.The databases included Pub Med,Google Scholar,MEDLINE,Scinapse,and EBSCO host.Findings from this review addressed the impact of rotavirus infection,associated threats and other preventive measures.Introducing useful health frameworks in pursuing possible methods such as improved water quality,exclusive breast feeding,improved laboratory diagnostics and outbreak surveillance,may be essential in addressing alternate approaches towards containment of the disease in Samoa and other Pacific Island Countries and Territories.

A New Discovery in Science: Far-Reaching Effects of the Hawaiian Islands on the Pacific Ocean-Atmosphere

IN PRAISE OF SHARING AS A STRATEGY FOR SUSTAINABLE HOUSING

A central theoretical principle of sustainability is the interdependence of economic,socio-cultural,environmental,and equity issues.The core idea is that sustainability is achieved only by balancing these elements.In practice,how­ever,this balance is rarely evidenced in the design and production of housing,despite the mass of research into sus­tainable housing.This paper discusses some of the political,economic and socio-cultural issues at work in sustainable housing typologies.It illustrates how the notion of sustainability has come to be represented by ecologically-focused models,while other approaches to sustainable housing design,such as shared housing models,are barely mentioned in the literature.The paper argues that modernist imperatives,such as demands for speed and status undermine sustainable housing design and obscure its meaning.The authors suggest that in the planning and design of sustain­able housing attention should be given to the sharing of resources and space as an added method of conservation,and conclude that current imbalances in research agendas and socio-cultural practices create a blind spot in the sustain­able housing debate.
