A Sumatran elephant killed by poachers

Another tragedy, following the consequences of the poachers' evil actions, strikes a poor animal. A one-year-old puppy Sumatran elephant died after falling into a trap set by poachers in Indonesia and losing half of her trunk.

The baby elephant was found alone and seriously injured. Conservation officials say they tried to save her life by amputating her trunk, but two days later she died of infection from her wounds. The Sumatran elephant is on the IUCN red list due to deforestation of its natural habitat in Borneo and poaching for the illegal ivory trade.

"We were unable to save her because the wound was serious and infected, says Agus Arianto, head of the Aceh Natural Resources Conservation Agency. We did our best to help her," said officials who deprived the animal.

Air Pollution and the negative role in hypertension

The effects of pollution on the respiratory system have already been known for some time, further studies have also shown a correlation between exhaust gases and other pathologies of other systems.

In addition to causing problems in the cardiovascular, ocular and nervous systems, it seems that pollution also plays a role in hypertension in adults and maybe children. Hypertension is a clinical condition in which the blood pressure in the arteries of the systemic circulation is elevated.

This leads to increased work on the heart. Blood pressure is summarized by two measures, systolic and diastolic, which depend on the fact that the heart muscle contracts (systole) and relaxes (diastole) between one beat and another.

Normal resting blood pressure is between 110 and 140 mmHg of systolic and between 60 and 90 mmHg of diastolic. Hypertension is considered if there is a pressure frequently equal to or greater than 140/90 mmHg. The study: Long-term association of ambient air pollution and hypertension in adults and in children: A systematic review and meta-analysis, published on the The Science of the total environment, in fact, said us: "The association of long-term ambient air pollution and hypertension has been inconsistently reported.

We performed an updated systematic review and meta-analysis to assess the association between long-term exposure to ambient air pollution and risk of hypertension in adults and in children. PubMed, EMBASE, and Web of Science were searched up to August 7, 2020 for published articles examining the association of long-term exposure to ambient air pollution, including particulate matter (PM; ultrafine particles, PM1, PM1-2.5, PM2.5 , PM2.5-10 and PM10), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulfur dioxide (SO2), ozone (O3), carbon monoxide (CO) and hypertension.

Pooled odds ratios (ORs) and 95% confidence intervals (CIs) for hypertension with each 10-μg / m3 increase in air pollutants were calculated by random-effects models. We included 57 studies (53 of adults and 4 of children) in the meta-analysis.

Risk of hypertension was significantly increased in adults with each 10-μg / m3 increase in exposure to PM2.5. Long-term ambient air pollution is a potential risk factor for hypertension in adults. More studies are needed to explore the effects of long-term air pollution on hypertension in children."
