Can gum disease delay pregnancy?

London, June 13: A common bacterium associated with gum disease may delay conception in young women, warns a new study.

“Our results encourage young women of fertile age to take care of their oral health and attend periodontal evaluations regularly,” said one of the researchers Susanna Paju of the University of Helsinki in Finland.

Periodontal (gum) disease is an inflammatory reaction to a bacterial infection below the gum line.

The study involved 256 healthy non-pregnant women (mean age 29.2 years, range 19 to 42) who had discontinued contraception in order to become pregnant.

They were enrolled from the general community from Southern Finland.

Participants were followed-up to establish whether they did or did not become pregnant during the observation period of 12 months.

Porphyromonas gingivalis, a bacterium associated with periodontal diseases, was significantly more frequently detected in the saliva among women who did not become pregnant during the one-year follow-up period than among those who did, according to the study published in the Journal of Oral Microbiology.

The levels of salivary and serum antibodies against this pathogen were also significantly higher in women who did not become pregnant.

Statistical analysis showed that the finding was independent of other risk factors contributing to conception, such as age, current smoking, socioeconomic status, bacterial vaginosis, previous deliveries, or clinical periodontal disease.

Women who had P. gingivalis in the saliva and higher saliva or serum antibody concentrations against this bacterium had a three-fold hazard for not becoming pregnant compared to their counterparts.

Increased hazard was nearly four-fold if more than one of these qualities and clinical signs of periodontitis were present.

“Our study does not answer the question on possible reasons for infertility but it shows that periodontal bacteria may have a systemic effect even in lower amounts, and even before clear clinical signs of gum disease can be seen,” Paju said.

“More studies are needed to explain the mechanisms behind this association,” Paju noted.

Young women are encouraged to take care of their oral health and maintain good oral hygiene when they are planning pregnancy, said Paju.

Delhi govt planning free dialysis at pvt hospitals: Jain

Dialysis

New Delhi, May 21 : The Delhi government is planning to make the dialysis procedure free at private hospitals and dialysis centres on a public-private-partnership basis, subject to conditions, Health Minister Satyendar Jain said today.

Jain said only those private hospitals and standalone centres which have more than 10 dialysis machines and are empanelled under the Delhi Government Employees Health Scheme or the Central Government Health Scheme would be eligible to become a partner in the project.

Delhi government through the Delhi Arogya Kosh will pay them Rs 1,274 per dialysis.

Delhi residents who have been living in the city for the past three years and having an annual income of less than Rs 3 lakh shall be eligible to avail the facility, Jain said.

The government is also installing dialysis machines at its own hospitals.

“We have installed 15 machines out of the 75 machines that we intend to install at various hospitals,” he said.

Jain said the idea behind providing the facility at private hospitals or dialysis centres is to cut the travel time for patients, who otherwise may have to go long distance to avail that facility at a government hospital.

“This would be like a reverse referral facility where patients would be referred to an empanelled hospital or centre nearby their home,” he said.

Jain said the government was in an “expansion mode” as far as health services were concerned.

“Five of our hospitals have already earned NABH entry-level accreditation – Pt Madan Mohan Malviya Hospital, Shri Dada Dev Matri Avum Shishu Chikitsalaya, Acharya Shree Bhikshu Hospital, Guru Gobind Singh Hospital and Dr Baba Saheb Ambedkar Hospital,” he said.

All you need to know about Nipah Virus

Nipah Virus

New Delhi, May 21: Nipah Virus is an emerging infectious zoonosis that causes severe disease in both animals and humans. It was first reported in Malaysia in 1998.

It is spread by fruit bats and can be transferred from a human through close contact, body fluids, saliva and cough.

Nipah Virus first appeared in domestic pigs and has been found among several species of domestic animals including dogs, cats, goats, horses and sheep.

According to World Health Organisation (WHO), Nipah virus (NiV) infection is a newly emerging zoonosis that causes severe disease in both animals and humans. The natural host of the virus are fruit bats of the Pteropodidae Family, Pteropus genus.

At present, there is no vaccine for either humans or animals. The primary treatment for human cases is intensive supportive care.

NiV infection in humans has a wide range of clinical presentations, from asymptomatic infection to acute respiratory syndrome and fatal encephalitis.

Generally, the human infection presents as an encephalitic syndrome marked by fever, headache, drowsiness, disorientation, mental confusion, coma, and potentially death.

Exercise 4-5 times daily to delay ageing

New York, May 21: Want to stay young for long? If so, start exercising four to five times a day as it may help keep your heart stay healthy and slow down ageing, according to researchers.

Research showed that different sizes of arteries are affected differently by varying amounts of exercise.

While exercising for about two to three days a week for about 30 minutes may be sufficient to minimise stiffening of middle-sized arteries, exercising for about four to five days a week is required to keep the larger central arteries youthful.

The study would help “develop exercise programmes to keep the heart youthful and even turn back time on older hearts and blood vessels”, said one of the study authors, Benjamin Levine from the University of Texas.

With age, arteries — which transport blood in and out of the heart — become prone to stiffening, increasing the risk of heart diseases.

For the study, published in The Journal of Physiology, the team examined 102 people over 60 years old, with a consistent lifelong exercise history.

The participants were divided into four groups depending on their exercise history — Sedentary: less than 2 exercise sessions per week; Casual Exercisers: 2-3 exercise sessions per week; Committed Exercisers: 4-5 exercise sessions per week and Masters Athletes: 6-7 exercise sessions per week.

A lifelong history of casual exercise (two-three times a week) resulted in more youthful middle-sized arteries, which supply oxygenated blood to the head and neck.

However, committed exercisers (4-5 times per week) also had more youthful large central arteries, which provide blood to the chest and abdomen, in addition to healthier middle-sized ones.

Larger arteries need more frequent exercise to slow down ageing, the researchers said.

The findings will help see “if we can reverse the ageing of a heart and blood vessels by using the right amount of exercise at the right time”, Levine explained.
