Life style related risk factors for cardiovascular disease among patients at a teaching hospital in Karachi

BACKGROUND: Cardiovascular disease is a leading cause for morbidity and mortality all over the world. It is important to study life style related, modifiable cardiovascular risk factors among patients, in order to devise preventive strategies. METHODS: We surveyed family practice patients visiting the out-patient clinics of Aga Khan University Hospital, Karachi. The interview was questionnaire-based and recorded the demographic profile of the patients, in addition to information on life style related cardiovascular risk factors. The ethical requirements for the study were met. SPSS computer software was used for data management. RESULTS: Fifty patients were surveyed and included 28 (56%) men and 22 (44%) women. Thirty seven (74%) respondents were married, nineteen (38%) had graduate education, twenty five (50%) were in private service, and twelve (24%) were housewives. Twenty six (52%) respondents were overweight or obese. Butter, cream, margarine and red meat was consumed by 17 (34%) and 32 (64%) respondents respectively. White meat, fresh fruits and vegetables were consumed by 30 (60%), 29 (58%) and 38 (76%) respondents respectively. Oil from vegetable sources was used by 49 (98%) respondents. Addition of table salt was found occasionally and always in 18 (36%) and 09 (18%) respondents respectively. Twenty seven (54%) respondents exercised at least twenty minutes, three times a week, while eleven (22%) were current smokers. CONCLUSIONS: Life style related modifiable risk factors are prevalent in patients reporting to our hospital. This offers an opportunity for preventive strategies, to prevent cardiovascular disease. Such surveys, followed by interventional strategies, are recommended to be followed by all Primary care facilities

Artisanal fish fences pose broad and unexpected threats to the tropical coastal seascape

Gear restrictions are an important management tool in small-scale tropical fisheries, improving sustainability and building resilience to climate change. Yet to identify the management challenges and complete footprint of individual gears, a broader systems approach is required that integrates ecological, economic and social sciences. Here we apply this approach to artisanal fish fences, intensively used across three oceans, to identify a previously underrecognized gear requiring urgent management attention. A longitudinal case study shows increased effort matched with large declines in catch success and corresponding reef fish abundance. We find fish fences to disrupt vital ecological connectivity, exploit > 500 species with high juvenile removal, and directly damage seagrass ecosystems with cascading impacts on connected coral reefs and mangroves. As semi-permanent structures in otherwise open-access fisheries, they create social conflict by assuming unofficial and unregulated property rights, while their unique high-investment-low-effort nature removes traditional economic and social barriers to overfishing

The importance of structural complexity in coral reef ecosystems\ud

The importance of structural complexity in coral reefs has come to the fore with the global degradation of reef condition; however, the limited scale and replication of many studies have restricted our understanding of the role of complexity in the ecosystem. We qualitatively and quantitatively (where sufficient standardised data were available) assess the literature regarding the role of structural complexity in coral reef ecosystems. A rapidly increasing number of publications have studied the role of complexity in reef ecosystems over the past four decades, with a concomitant increase in the diversity of methods used to quantify structure. Quantitative analyses of existing data indicate a strong negative relationship between structural complexity and algal cover, which may reflect the important role complexity plays in enhancing herbivory by reef fishes. The cover of total live coral and branching coral was positively correlated with structural complexity. These habitat attributes may be creating much of the structure, resulting in a collinear relationship; however, there is also evidence of enhanced coral recovery from disturbances where structural complexity is high. Urchin densities were negatively correlated with structural complexity; a relationship that may be driven by urchins eroding reef structure or by their gregarious behaviour when in open space. There was a strong positive relationship between structural complexity and fish density and biomass, likely mediated through density-dependent competition and refuge from predation. More variable responses were found when assessing individual fish families, with all families examined displaying a positive relationship to structural complexity, but only half of these relationships were significant. Although only corroborated with qualitative data, structural complexity also seems to have a positive effect on two ecosystem services: tourism and shoreline protection. Clearly, structural complexity is an integral component of coral reef ecosystems, and it should be incorporated into monitoring programs and management objectives

Supporting Enhancement of Stewardship in Small-Scale Fisheries: Perceptions of Governance Among Caribbean Coral Reef Fishers

Small-scale fishing livelihoods dependent on Caribbean coral reefs face an uncertain future with global climate change and mounting anthropogenic pressures threatening ecosystem integrity and resilience. In the context of future threats to coral reefs, improved governance is critical to enhance the efficacy of coral reef management. Recent research places increasing emphasis on identifying governance arrangements that enable participation and engagement, with the improved ‘social fit’ of institutions expected to engender stewardship among fishers. However, few studies have examined the perspectives of resource users in relation to a wide range of articulated principles for good governance processes. This study contributes to an improved understanding of how fisher perceptions relate to diverse governance arrangements in the Wider Caribbean Region. We quantify perceptions among 498 reef-dependent fishers in relation to principles of ‘good governance’ in 12 communities across four Caribbean countries: Barbados, Belize, Honduras, and St. Kitts and Nevis. We describe perceptions relating to two underlying governance themes – institutional acceptance (reflecting principles of legitimacy, transparency, fairness, and connectivity) and engagement in reef governance (reflecting principles of accountability and inclusiveness). In addition, we identify socio-demographic factors associated with each set of perceptions and explore the implications for future governance of small-scale Caribbean reef fisheries. The findings suggest that an understanding of heterogeneous perceptions within small-scale fisheries can inform more targeted interventions to improve the fit of governance arrangements for different groups. Governance may be more effective if perceptions are used to identify areas in which to pursue greater engagement of resource users in stewardship
