London, April 4: Regular intake of coffee or caffeine by patients with Alzheimer's disease may deteriorate their neuropsychiatric symptoms, including but not limited to anxiety, say researchers.

 While it is well known that memory problems are the hallmarks of Alzheimer's disease, this dementia is also characterized by neuropsychiatric symptoms such as anxiety, apathy, depression, hallucinations, paranoid, sundowning and more known as  Behavioral and Psychological Symptoms of Dementia (BPSD) which may be strongly present already in the first stages of the disorder.

The results indicate that caffeine worsened these symptoms in mice with Alzheimer's.

The researchers also discovered significant effects, especially in relation to neophobia -- a fear of everything new -- anxiety-related behaviours, and emotional and cognitive flexibility.

"The mice develop Alzheimer's disease in a very close manner to the human patients with early-onset form of the disease," said lead author Raquel Baeta-Corral from the Autonomous University of Barcelona in Spain.

"They not only exhibit the typical cognitive problems but also a number of Behavioural and Psychological Symptoms of Dementia (BPSD)-like symptoms, so it is a valuable model to address whether the benefits of caffeine will be able to compensate its putative negative effects."

For the study, the team analyzed the effect of caffeine on normal ageing mice and familial Alzheimer’s models.

However, coffee has also been suggested as a strategy to prevent dementia, both in patients with Alzheimer's disease and in normal ageing processes, due to its action in blocking molecules - adenosine receptors - which may cause dysfunctions and diseases in old age.

But "our observations of adverse caffeine effects in an Alzheimer's disease model together with previous clinical observations suggest that an exacerbation of BPSD-like symptoms may partly interfere with the beneficial cognitive effects of caffeine", the researchers said.

Kota (PTI): In the wake of the death of four women due to infection after C-section delivery, Rajasthan principal secretary (health) Gayatri Rathore has ordered strict adherence to treatment protocols in emergency operation theatres, ICUs and other critical units in hospitals.

Rathore on Monday night visited the ICU of the Super Speciality Block at New Medical College Hospital here and spoke to the relatives of three postpartum women, Pinki, Dhanni Bai, and Aarti, about their health.

She also spoke to Ragini Meena, who is admitted to the ICU, and said the condition has improved considerably.

Four women, two each at NMCH and JK Lone Hospital, died after developing complications following a caesarean delivery.

Pinki Mahawar, 30, wife of Chandra Prakash, a daily wage labourer, died on Monday of a similar infection after a C-section delivery.

Priya Mahawar, 22, died after developing a kidney infection post-C-section in JK Lone Hospital on the intervening night of May 9 and May 10.

Before her, two other women, Payal and Jyoti Nayak, aged 26 and 19, died on May 5 and May 7, in the New Medical College Hospital.

Meanwhile, Rathore said the patients' treatment is being monitored by senior nephrologist Dr Dhananjay Agrawal, according to a statement.

She was briefed by Dr Vikas Khandelia on the treatment of all postpartum women who got the infection.

According to a statement, she also met Chandrakala and Sushila, who have been shifted to the nephrology ward, and enquired about their health. Their relatives said that both women are now in a much better condition.

Later on Monday, the official chaired a meeting at NMCH, took information from senior doctors and discussed all possible causes behind the deaths due to infection.

She said that treatment protocols and infection-free operation theatres should also be ensured at district hospitals and PHC-CHC levels, and warned of action in case of any negligence.

Rathore said an investigation is underway into every aspect of the case. Action has already been taken against doctors and nursing personnel found prima facie guilty, the statement said.

According to the statement, Rathore said regular sterilisation must be ensured in these emergency units to prevent any possibility of infection. Equipment and machines used during treatment should also be sterilised as per protocol.

Hospital in-charges and unit heads should regularly monitor whether all treatment protocols are being followed properly, it said.

Rathore said hospital superintendents may also use RMRS funds for immediate requirements in ICUs and operation theatres.

The meeting was attended by District Collector Piyush Samaria, City Superintendent of Police Tejaswini Gautam, Food Safety and Drug Control Commissioner Dr T Shubhamangala, Director of Public Health Dr Ravi Prakash Sharma, Principal of Kota Medical College Dr Nilesh Jain, Dr Dhananjay Agrawal, and doctors from Jaipur.
