Multiple bouts of blood-feeding by mosquitoes reduce the incubation period for malaria parasites and increase malaria transmission potential, said a study. Given that mosquitoes feed on blood multiple times in natural settings, the results published in the journal PLOS Pathogens suggest that malaria elimination may be substantially more challenging than suggested by previous experiments, which typically involve a single blood meal.

Malaria remains a devastating disease for tropical and subtropical regions. In natural settings, the female Anopheles gambiae mosquito — the major malaria vector — feeds on blood multiple times in her lifespan. Such complex behavior is regularly overlooked when mosquitoes are experimentally infected with malaria parasites, limiting our ability to accurately describe potential effects on transmission.

In the new study, the researchers examined how additional blood-feeding affects the development and transmission potential of Plasmodium falciparum malaria parasites in An. gambiae females. “We wanted to capture the fact that, in endemic regions, malaria-transmitting mosquitoes are feeding on blood roughly every 2-3 days,” said W. Robert Shaw from Harvard T.H. Chan School of Public Health in the US.

“Our study shows that this natural behavior strongly promotes the transmission potential of malaria parasites, in previously unappreciated ways.” The results showed that an additional blood feed three days after infection with P. falciparum accelerates the growth of the malaria parasite, thereby shortening the incubation period required before transmission to humans can occur.

Traditional players are very strong in the consumer laptop market.

By Md Waquar Haider

When popular smartphone brands like Xiaomi and realme entered the laptop market in India last year, they were expected to shake the existing giants, specifically under the Rs 50,000 category. However, chip shortage and supply crunch have somewhat dented their plans to make a significant mark to date. According to industry experts, the issue with smartphone makers entering the laptop category is two-fold. The first one is a massive supply crunch in the laptop component market and only big brands are able to get volume and supplies.

The other factor is that the traditional players are very strong in the consumer laptop market. Top 3 players control more than 70 per cent of the market and strong portfolio, distribution, and channel reach as well as brand marketing has helped them massively. "New brands can surely make a dent in the consumer laptop market but are challenged by supply issues right now. Watch out for them in 2022 as and when supply situation eases up," Navkendar Singh, Research Director, Client Devices & IPDS, IDC India told IANS.

Dominated by HP Inc, Lenovo and Dell, the traditional PC market (inclusive of desktops, notebooks, and workstations) in India continued to be robust as the shipments grew by 50.5 per cent year-over-year (YoY) in the second quarter (Q2), according to IDC. Notebook PCs continue to hold more than three-fourth share in the overall category and grew 49.9 per cent YoY in 2Q21, reporting a fourth consecutive quarter with over 2 million units. Desktops also indicated a recovery as shipments grew 52.3 per cent YoY after recording the lowest shipments of the decade in 2Q20.

According to Prabhu Ram, Head, Industry Intelligence Group, CMR, driven by the pandemic and the associated accelerated pivot to remote work, learn and unwind culture, PCs have been witnessing heightened demand. "Despite the current supply chain constraints, PCs are here to stay in the new never normal. In the run-up to the festive season, established PC market leaders will continue to leverage their brand salience and gain market share," Ram told IANS.

The research, led by researchers at the University of Plymouth, showed that antidepressant mirtazapine offered no improvement in agitation for people with dementia

A drug used to treat agitation in people with dementia is no more effective than a placebo, and might even increase mortality, according to a new study published in The Lancet. The research, led by researchers at the University of Plymouth, showed that antidepressant mirtazapine offered no improvement in agitation for people with dementia -- and was possibly more likely to be associated with mortality than no intervention at all.

Agitation is a common symptom of dementia, characterized by inappropriate verbal, vocal or motor activity, and often involves physical and verbal aggression. Non-drug patient-centered care is the first intervention that should be offered but, when this doesn't work, clinicians may move to a drug-based alternative.
