EPIDEMIC CONTROL VIA EDUCATION: SRI LANKA’S KIDNEY DISEASE CASE September 4, 2008

Erle Frayne Argonza

 

Kidney diseases are potentially fatal, and I’d say this from out of experience. I suffered from nephritis at Age 8, and lucky was I to survive a two-year agony due to medication availability in my home town (it was almost a 4th World town then!). That ailment ruined my chance to do athletics in grade school, it made me shrink in esteem, and the weak kidney (aside from weak tonsils) contributed to my sickliness since then.

 

So it pays not only to understand the ailment, its diagnostics and medication. It pays all the more to know the preventive side of the ailment or any ailment for that matter. If the diagnostics side shows some shades of grey, then that could surely baffle the experts (medical scientists) and specialists, as a case proves in Sri Lanka.

 

Read the news below about Sri Lanka. The ‘good’ news about it is that the ailment has provided some nice research problems for the public health experts and pharmacologists.

Sri Lanka kidney disease epidemic leaves doctors baffled

Almost all those affected are men from farming families

Doctors and researchers are puzzled by a sharp rise in chronic kidney disease among farming communities in the North Central province of Sri Lanka.

The number of cases has been steadily rising since the disease first came to light around eight years ago. Over 18,000 cases have now been reported, with cases in Eastern and Uva provinces as well as North Central.

In 2003, almost 200 hundred patients died from renal failure in the North Central province and the figure is increasing every year. Over half the population there is engaged in agriculture.

Almost all those affected are men from farming families without pre-existing conditions than can lead to renal disease, such as hypertension or diabetes.

The absence of clinical symptoms until the late stages of renal failure is also puzzling researchers and making early diagnosis difficult, leading to many deaths.

Local researchers have come up with several possible risk factors for the disease, including high groundwater fluoride content in some affected areas, leaching of heavy metals such as cadmium from agricultural chemicals into water sources, exposure to inorganic pesticides and fertilisers, and usage of aluminium vessels to store drinking water.

Several studies conducted by local researchers have found a strong link between high cadmium concentrations in water sources and high disease prevalence.

A team of medical experts from the WHO visited Sri Lanka to assess the situation in May this year. They recommended that non-affected agricultural regions be used as control areas in studies to find the disease’s cause, and preventative measures such as using clay pots to store water are used.

A long-term clinical study was also proposed by the WHO but has yet to be implemented, Rohana Dayaratne, a geneticist and physician attached to the National Hospital of Sri Lanka in Colombo, told SciDev.Net. 

He says local and international researchers should lead a combined effort to identify the causes and preventive measures, and that local researchers have a good knowledge about ground realities that should be combined with the financial and other resources of the international community.

The majority of the affected farming communities were settlers from different parts of the country, he says, meaning that there could be a genetic component to the disease.

The growing number of patients suffering from chronic renal disease is becoming a heavy burden on the health sector, as the treatments — dialysis and organ transplants — are costly procedures.

Efforts are underway to educate the public about risk factors, maximise early diagnosis with weekly clinics and field visits to vulnerable areas, and introduce preventive measures.

 

CHILE BIOFUELS THE DAY

Erle Frayne Argonza

 

Amigos y amigas, Buenos dias again!

 

Chile has boosted its own path to renewable energy by recently priming up its research & development efforts in biofuels. This is a long shot in the arm for Chile which had moved on to an ‘emerging market’ status over the last two (2) decades.

 

Below is the brightening news about Chile’s biocombustible development.

 

Happy reading! Venceremos!

Chile enfatiza biocombustibles de tecnología avanzada

María Elena Hurtado

3 julio 2008 | ES

Los bosques sureños son materia prima ideal para producir combustibles líquidos

Instituto Forestal de Chile

[SANTIAGO DE CHILE] La asignación, en los próximos días, de hasta 6 millones de dólares a consorcios público-privados para la investigación, desarrollo y comercialización de biocombustibles de tecnología avanzada, o de segunda generación, confirma el anuncio sobre la prioridad que Chile dará a este tipo de biocombustibles que la presidenta Michelle Bachelet hiciera el 21 de mayo durante la exposición anual al Parlamento .

Los biocombustibles de segunda generación – que se obtienen de materias lignocelulósicas como los rastrojos o residuos de trigo y deschos de la silvicultura y madera – tienen la ventaja de no competir con los alimentos y aprovechar residuos. El proceso de conversión en bioetanol es más largo y complicado que el del bioetanol tradicional y costaría más que los demás biocombustibles

InnovaChile, dependiente del Ministerio de Economía, financiará hasta en un 60%, es decir hasta US$6.3 millones, a consorcios que propongan planes de investigación, desarrollo y comercialización de biocombustibles a partir de material lignocelulósico.

Los consorcios seleccionados deberán constituirse este año y obtener resultados en cinco años como máximo, aunque se espera que en tres años ya puedan entrar al mercado. Dos consorcios formados por empresas forestales y universidades – Bioenercel y ForEnergy – ya están desarrollando proyectos de estas características en el país.

“Aunque la superficie forestal chilena podría abastecer una industria de combustibles de segunda generación…lo más conveniente para el país es continuar plantando los abundantes terrenos forestales todavía disponibles pero con nuevas especies especialmente seleccionadas para uso energético, y de ese modo, evitar una competencia entre los dos tipos de uso de material prima,” comentó a SciDev.Net el Subsecretario de Agricultura, Reinaldo Ruiz.

Hasta fines del 2007 Chile -junto con Ecuador y Venezuela- eran los únicos países sudamericanos que no tenían leyes que promovieran los biocombustibles (Venezuela por ser productor de petróleo).

Pero Chile se ha estado poniendo rápidamente al día. En marzo de este año el Congreso aprobó una ley sobre energías renovables no convencionales que incluye los biocombustibles. En mayo se autorizó la mezcla de bioetanol con gasolina en 2 por ciento y 5 por ciento del volumen resultante de la mezcla. También se eximió a los biocombustibles del impuesto a la gasolina y el diesel, y las empresas estatales de cobre y petróleo – CODELCO y ENAP – empezarán a usar biodiesel en sus maquinarias para evaluarlo.

Finalmente, el 30 de junio se creó la Comisión Asesora Interministerial en Materia de Biocombustibles que asesorará a todos los organismos públicos involucrados en esta materia, fijará directrices, propondrá orientaciones estratégicas y prestará apoyo para implementar políticas.
