Ultrasound can move, break up kidney stones in awake patients: Study

Published

on

 A simple ultrasound technique can be used to move, reposition or break up kidney stones, all while the patient is awake, a new study has revealed.

The technique combines the use of two ultrasound technologies to offer an option to move kidney stones out of the ureter with minimal pain and no anaesthesia, according to doctors from University of Washington School of Medicine (UW Medicine).

In the procedure, the physician uses a handheld transducer placed on the skin to direct ultrasound waves towards the stone.

The ultrasound can then be used to move and reposition the stones to promote their passage, a process called ultrasound propulsion, or to break up the stone, a technique called burst wave lithotripsy (BWL).

Unlike shock wave lithotripsy, which is the standard procedure now in use and requires sedation, this technology doesn’t hurt, said lead author Dr M Kennedy Hall, an emergency medicine doctor at UW Medicine.

“It’s nearly painless, and you can do it while the patient is awake, and without sedation, which is critical,” Hall said.

The research team hopes that, with this new technology, the procedure of moving or breaking up the stones could eventually be performed in a clinic or emergency room setting.

Stones in the ureter, which leads from the kidney to the bladder, can cause severe pain and are a common reason for emergency department visits.

Most patients with ureteral stones are advised to wait to see if the stone will pass on its own.

However, this observation period can last for weeks, with nearly one-fourth of patients eventually requiring surgery, Hall noted.

Twenty-nine patients participated in the new study. Sixteen were treated with propulsion alone and 13 with propulsion and burst wave lithotripsy. In 19 patients, the stones moved.

In two cases, the stones moved out of the ureter and into the bladder.

Burst wave lithotripsy fragmented the stones in seven of the cases. At a two-week follow up, 18 of 21 patients (86 per cent) whose stones were located lower in the ureter, closer to the bladder, had passed their stones.

In this group, the average time to stone passage was about four days, the study noted.

One of these patients felt “immediate relief” when the stone was dislodged from the ureter, the study stated.

India’s metro rail network headed to become world’s 2nd largest: Minister

Published

New Delhi, Dec 19: India is well on its way to having the second-largest metro network in the world with 993 km of Metro rail already operational in 23 cities across the country and about 997 km under construction in 28 cities, Minister for Housing & Urban Affairs Manohar Lal Khattar has said.

The Union Minister made an elaborated presentation on Urban Transport to the consultative committee members of Parliament attached to MoHUA, according to an official statement on Thursday.

He emphasised that Urban Mobility is an important aspect to tackle the rising urban population and the government is working relentlessly to strengthen the Urban Transport Network across the country.

The participants were briefed about Metro Rail Policy 2017 and Metro Networks across the cities including Delhi, Jaipur, Patna and Lucknow.

The members were also briefed about the ongoing projects of RRTS (Regional Rapid Transport System) high speed train network, including its funding pattern.

The briefing to members also covered initiatives taken to promote indigenisation of technologies under Make in India and promote Aatmanirbhar Bharat.

The briefing also mentioned PM-eBus Sewa, a scheme for augmenting city bus operations by deploying 10,000 e-buses on the Public Private Partnership (PPP) model.

Salient features of this scheme include deployment of 10,000 e- buses on PPP model, bus operations support for 10 years, support for development and the upgradation of bus depots and support for behind-the-meter power infrastructure.

The service aims to cover cities with 3 to 40 lakh population.

The briefing also covered ‘One Nation One Card’, an indigenously developed National Common Mobility Card (NCMC), launched by Prime Minister Narendra Modi in March 2019 to enable seamless travel through Metro, Rail, Bus and other Public Transport Operators.

During the meeting, the Members of Parliament raised issues pertaining to urban mobility which included matters related to last mile connectivity, enhancement of amenities, metro connectivity in their respective states, scaling up of metro operations in the country, ease of travel and passenger comfort.

The MPs who attended the meeting include Rajiv Pratap Rudy, Dinesh Sharma, Ajay Maken, Kamaljeet Sherawat, P.N. Vasava, Prof V.E. Gaikwad, Kavita Patidar, B.M. Sutariya , V.E. Vaithilingam , G. Lakshminarayana, Ramvir Singh Bidhuri and Y. Chandolia.

The Minister asked the officials that suggestions from members received should be reviewed and information sought by them should be provided.

1st malaria vaccine shows promise against rising cases: Report 

Published

on

New Delhi, Dec 19: The first blood-stage malaria vaccine RH5.1/Matrix-M has the potential to be a component within a developing malaria vaccine strategy, said a report on Thursday.

The report by GlobalData, a data and analytics company, showed that there are 11 other malaria vaccines currently in Phase II development.

As per a recent study by researchers in Burkina Faso and the UK, RH5.1/Matrix-M is safe, effective, and highly immunogenic.

The double-blind, randomised, controlled, phase 2b trial, analysed 361 children between the ages of 5 and 17 months showed that RH5.1/Matrix-M is 55 per cent effective against clinical malaria when administered in a delayed third-dose regimen at 0, 1, and 5 months.

Further, the vaccine demonstrated over 80 per cent efficacy against high levels of malaria parasites, which indicates the vaccine would be effective at preventing severe disease. RH5.1/Matrix-M was found to be generally safe and well-tolerated, with no serious adverse events being reported, revealed the findings published in The Lancet Infectious Diseases.

“RH5.1/Matrix-M has the potential to be the first blood-stage malaria vaccine brought to market. This could be a much-needed addition to the currently available malaria vaccines and provide an important second line of defense for those most at risk of contracting malaria,” said Stephanie Kurdach, Infectious Disease Analyst at GlobalData.

Malaria is a mosquito-borne disease, caused by parasitic Plasmodium protozoans, spread primarily through the bite of an infected female Anopheles mosquito. Typically, the symptoms can range from fever, chills, and headache to confusion, seizures, and difficulty breathing.

Kurdach noted that although there is progress and some nations have been certified as malaria-free, the burden of malaria remains high, particularly within the World Health Organization’s (WHO) African Region.

There are currently only two malaria vaccines, that are WHO prequalified and recommended for use in children: GSK’s Mosquirix and Serum Institute of India’s R21/Matrix-M.

These vaccines work to intercept malaria infection by targeting the early sporozoite stage of the parasite.

However, as immunity wanes with time, sporozoites can infect the liver and lead to blood-stage clinical malaria infection.

The development of a blood-stage malaria vaccine would replace these vaccines as well provide a second line of defense.

“There are 11 other malaria vaccines currently in Phase II development, including pre-erythrocytic vaccines and blood-stage vaccines from manufacturers such as BioNTech, GSK, the National Institute of Allergy and Infectious Diseases (NIAID), and Vac4All SAS,” Kurdach said.

“No new malaria vaccines are in Phase III development or pre-registration at this time,” she added.
