Six of the top medical news stories from China

1. China has a huge shortage of midwives, and would need a further 800,000 to meet the WHO standard of one for every thousand women of child-bearing age, according to a new report. Health officials say the problem will worsen as China adopts a two child policy.

2. Efforts to control pneumococcal disease and Haemophilus influenzae type b (Hib) in children by vaccination are failing due to low immunisation rates and delayed immunisation, a study from Shanghai shows. A review of vaccination records for 28,000 children up to the age of seven found that 51% had one dose of Hib vaccine and 11.4% had one dose of pneumococcal vaccine. Only 8.2% of children had Hib vaccine at the right time and only 0.5% had timely pneumococcal vaccine. Rates were particularly poor for migrant children, the study found.

3. Rates of hypertension have increased in China and yet treatment and control of the condition remain poor, according to researchers from Shandong. In a study of more than 4000 people they found that the incidence of hypertension increased from 2.9 per 100,000 people in 1991–1997 to 5.3 in 2004–2009 Antihypertensive treatment and control rates for hypertension were 5.7% and 1.7% in 1991–1997 and 19.9% and 7.6% in 2004–2009, respectively.

4. The rate of disabilities from road crashes in China has skyrocketed as the number of cars on the road has increased over the last two decades. The incidence rate for road traffic disabilities increased over time from 1.50 per 100,000 people in 1980 to 11.2 per 100 000 persons in 2005, according to Professor Zheng Xiaoying of the Institute of Population Research, Peking University.

5. Malaria is still a major problem in central China especially during floods and rainy periods of the summer. A study from Mengcheng County, Anhui found that there were 3683 malaria were notified during the study period of May to October 2007 Most of the cases occurred a week to a month after flooding and waterlogging. Public health action should be taken to control the potential risk of malaria epidemics after wet weather, the researchers from Shandong University said.

6. The recent outbreaks of H7N9 avian influenza also resulted in many mild and asymptomatic infections as well as severe life threatening cases, researchers from Guangdong have reported. Their surveillance program noted 21 cases of infection in Guangzhou, China in 2013 and 2014, of which several were mild or asymptomatic infection. Family clusters occurred, suggesting limited person-to-person transmission of the H7N9 virus, they said.

HPV vaccine delay | Baidu medical fraud | Malaria system success | Gassers in short supply | GSK case won't stop bribery

1. China may be delaying approval of HPV vaccines made by foreign companies until the country has a homegrown competitor, according to Global Times. The HPV vaccines Gardasil and Cervarix are still not available in China despite 30,000 women dying in China every year of HPV-related cervical cancer. Some Chinese doctors and officials claim there are ethnic differences in vaccine responses between Chinese and Europeans, and clinical trials that in Chinese people are needed to ensure of the vaccines' safety and efficiency on Chinese.

2.  Baidu earns its fortune by promoting fraudulent medical information at the cost of health and even lives, critics say. The search engine site is the main avenue used by illegal drug manufacturers and illegal hospitals to advertise in China, they claim. Many drugs that are explicitly banned by the China Food and Drug Administration (CFDA) are still on promotion on Baidu, an article in Daily Kos says.

3. A '1-3-7' system of dealing with malaria cases that is very successful and could be a model for other countries, researchers from the Jiangsu Institute of Parasitic Diseases claim. The system is based on case reporting within one day, case investigation within three days. and focus investigation and action within seven days.Since the system was implemented in 2012 the proportion of cases investigated in 3 days has reached 100%, and seven-day action rates are 50% and rising.

4. China has a shortage of 200,000 anesthesiologists as doctors avoid the speciality due to low salaries, heavy workloads and lack of a strong training system, experts say. A conference was told that China has only 100,000 anesthesiologists but needs 300,000. Eight anesthesiologists died of overwork last year, according to Yu Weifeng, head of the anaesthesiologist branch of the Chinese Medical Doctors Association.

5. A cure for the endemic corruption in China's healthcare system is still far away despite the scare campaign against executives of British pharma company GSK, the online magazine Caixin says. While the crackdown makes the authorities look like they are being tough on bribery for prescribing, the reality is that doctors still accept commissions and there is no fix for the 'demand side' of the bribery equation, the magazine says. The health ministry cannot afford to alienate doctors, who are central to the problem, it concludes.

Seven important items of medical research from China

N95 masks don't work for Chinese faces
The specialised N95 face masks used to protect against infections such as influenza are not shaped to fit Chinese faces and most would fail to prevent transmission because of poor fit and leakage, tests by Wuhan researchers have shown. Evaluation tests on ten different types of N95 mask found that only two performed within acceptable limits to prevent transmission of infections. Performance of some masks was better when users were trained and they were specially fitted, the study in PLOS One showed.
"This study indicated that widely used N95 filtering facepiece respirators in China didn't fit well and can't provide desired protection for respirator users," the researchers concluded.

Malaria from Africa now a problem in China
Malaria has been virtually eliminated in China but doctors now face the problem of treating malaria in Chinese workers who have returned from Africa. In Jiangsu there have been 918 malaria cases and six deaths in the last decade due to malaria imported from other countries. The imported cases make up 12% of all malaria cases and account for all malaria deaths, according to researchers from the Jiangsu Institute of Parasitic Diseases, Wuxi, writing in the Malaria Journal.

No cardiovascular treatment for many Chinese patients
Two out of three Chinese people with cardiovascular disease are still going untreated, a major study has found. Data from of 512,891 Chinese adults showed that 5% had a history of cardiovascular disease. However, of these only 35% had been treated with any cardiovascular medicine for secondary prevention such as statins, antiplatelet drugs or antihypertensives. The findings from a team from Oxford and Beijing universities, are published in the International Journal of Cardiology.

Shenzhen women have high rates of HPV
More than one in ten women in Shenzhen are have HPV serotypes that put them at risk of cervical cancer, researchers say. A study of 4, 413 women measured HPV infection rates and the prevalance was 14%. The high risk HPV types 16 and 18 that are likely to cause cervical cancer were found in 3.5% of women and 1.27% of women, according to the study published in the Asia Pacific Journal of Cancer Prevention.

Avian H7N9 flu virus on way to mutation
The H7N9 influenza virus is genetically much more diverse than previously thought, suggesting that it is reassorting and closer to mutating into a pandemic virus, researchers from the Jiangsu Provincial Center for Disease Control and Prevention, have shown. They report their findings in Nature.

Medical teacher burnout
Staff at medical colleges in China have high rates of burnout, a study from Shanxi shows. Staff who had a love of teaching and those who received praise and recognition were less likey to suffere burnout, according to the study in Archives of Environmental & Occupational Health.

Pancreatic cancer in Shanghai
The diagnosis and treatment of pancreatic cancer in Shanghai has room for improvement, according to researchers from Fudan University. In a review of management of pancreatic cancer published in Cancer Letters, they report that most patients miss out on the recommended histologically verified diagnosis and the 1-year and 2-year survival rates were 35% and 14.4%, respectively.
