Need to clamp down on prescription-less sales of antibiotics

Need to clamp down on prescription-less sales of antibiotics


Most of us have the experience of getting antibiotics from a pharmacist without a doctor’s prescription. Commercial pressures propel the pharmacist to commit a blatant violation of law. Nobody complains, because whether the ailment goes after taking the antibiotic or not, the episode of buying the medicine without a prescription is quickly forgotten.

But several studies have emerged to show that the rampant practice of consuming antibiotics indiscriminately silently contributes to a much bigger health issue, namely, antimicrobial resistance (AMR, aka antimicrobial drug resistance or ADR). This refers to the infection causing microbes developing resistance to an antibiotic — the medicine fails to cure.

Studies show that India has a high prevalence of AMR. For example, in 2019, a group of Indian and American researchers led by Sumanth Gandra of the Centre for Disease Dynamics, Washington DC, conducted a patient-level antimicrobial susceptibility test (AST) over 5,103 patients from ten hospitals. “The overall mortality rate of patients was 13.1 per cent and there was a significant relationship between multi-drug resitance and mortality,” the authors say in their paper.

AMR comes from several sources. “The OTC sale of antibiotics is recognised as a pathway for the emergence of antimicrobial resistance; a serious public health challenge in need of urgent regulatory responses,” says another, 2021 paper which delves into the regulatory aspects of antibiotics dispensation. The authors conducted a study of 261 pharmacies in Bengaluru, in which the pharmacy was requested to give antibiotics, without a prescription, for two ailments — for an adult complaining of upper respiratory tract infection and a child suffering from acute gastroenteritis. As many as 174 pharmacies gave the medicine over-the-counter (OTC), even though neither condition didn’t require antibiotic treatment.

Similarly, in Tamil Nadu “observations and interviews with pharmacists at 24 pharmacies revealed that 78.7 per cent of antibiotics sold within the study period were given without a prescription.” Another study of the same authors reported that of the 40 New Delhi pharmacists, none said they refused to sell antibiotics without prescription. “Despite being illegal, OTC sales of antibiotics by pharmacies without a valid prescription from a registered medical practitioner (RMP) appear widespread in India, highlighting serious problems around the regulation of this pathway for emergence of AMR,” the paper says.

Often people take antibiotics even for viral infections, which are indifferent to antibiotics and self-limiting.

The Drugs and Cosmetics Act, 1940, and the Drugs and Cosmetics Rules (DCR), 1945, designates all antibiotics as prescription drugs under the Schedule H category. In 2014, an amendment was made to the Schedule H category to include second- and third-generation antibiotics into a new category called Schedule H1. For Schedule H1 drugs, pharmacists are required to maintain a separate register for the sale of these antibiotics and retain prescription copies. This amendment was implemented to curb the widespread practice of antibiotic purchase from retail pharmacies without a valid prescription (old or outdated). “However, several studies before and after 2014 indicate that consumers can still purchase antibiotics without a valid prescription as pharmacists still dispense antibiotics to their customers/clients/patients by attending to their symptoms,” notes yet another paper.

Inside India’s XR revolution

Inside India’s XR revolution


As we navigate through a transformative era shaped by Artificial Intelligence and Machine Learning, a new technological frontier is on the horizon — eXperiential Technologies (XT), also known as Spatial Technologies. The XT wave includes Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR), which are not just reshaping entertainment through immersive gaming experiences but also revolutionising learning with simulators and interactive applications. Moreover, XT is carving out significant roles in sectors like healthcare, travel and tourism, offering experiential solutions that redefine our interaction with the digital world.

Since many of these technologies are used by the gaming and entertainment industries, there’s a fair amount of conflation between the “lighter” and more “serious” usage of these tech. However, the DNA of these two sectors — entertainment vs other industries — are so different, and the skill sets required are vastly diverse. Therefore it is essential to advocate for strategic policies that will bridge these disparities

In this context, the IIT Madras’ IoE Research Center for Virtual Reality and Haptics released a whitepaper on the AR/VR/MR and eXtended Reality (XR) in India to act as a basis for policy and framework recommendations for this space. The report forecast that by 2030, XR would see significant advancements including powerful and compact devices, advanced sensor technologies, 6G connectivity and convergence with other technologies. And by 2047, XR would undergo further transformations with holographic displays and light-field displays, neural interfaces, quantum computing, decentralised platforms, and enhanced global collaboration. Therefore, it is imperative that efforts and investments into this set of technologies be guided properly to ensure India’s share in this space.

Some History

The roots of XT can be traced back to mid-20th century when pioneers like Morton Heilig and Ivan Sutherland laid the foundation for immersive technologies. Heilig’s Sensorama in the 1950s and Sutherland’s groundbreaking work on head-mounted displays in the 1960s marked the early experiments in creating immersive experiences.

The concept of Virtual Reality gained momentum in the 1980s and ’90s with the development of advanced computer graphics and simulations. Companies like VPL Research played a significant role in popularising VR applications for industries such as gaming, training and simulation.

Augmented Reality, which overlays digital information onto the real world, started to gain prominence in the early 2000s with the advent of smartphones and wearable devices. Applications like AR gaming, navigation and marketing began to showcase the potential of blending digital content with the physical environment.

Mixed Reality, which combines elements of both VR and AR, emerged as a powerful tool for creating interactive and immersive experiences. Companies like Magic Leap and Microsoft HoloLens pushed the boundaries of MR technology, enabling users to interact with digital objects in real-world settings.

Extended Reality emerged as a comprehensive term encompassing VR, AR, and MR technologies, offering a spectrum of immersive experiences.

Benefits, challenges

XR/XT bring immense benefits by enabling immersive experiences as well as enhanced interactivity (multi-modal, including voice, touch, gestures etc.) which are important for training and skill development in otherwise risk-prone sectors such as healthcare and exploration.

As a general advantage, working across industries, it enables remote collaboration and interaction across locations as well as improve inclusivity and accessibility for individuals with disabilities and special needs. However, XR/XT face some challenges as well, the foremost of which is hardware capabilities and availability of capable hardware at affordable prices.

XR applications also raise concerns about data privacy, security vulnerabilities, and potential misuse of personal information, requiring robust safeguards and regulations.

New things to learn

Perception engineering forms the foundation of XR, representing a new engineering discipline that leverages insights into human perception to design XR hardware and software. This novel field merges traditional engineering methodologies with an understanding of human perception, harnessing these insights to innovate in XR development.

Central to perception engineering is the consideration of sensory perception, cognitive load, motion sickness, and other dimensions of human perception, ensuring that XR technologies are not only functional but also ergonomic and user-friendly.

Perception Algebra is an emerging mathematical field that applies algebraic principles to analyse the interactions of different perceptual systems at sensory, perceptual, and cognitive levels.

Perception Physiology investigates the bidirectional relationship between perception and physiology, exploring how each influences the other.

Recommendations

Recognising the advantages of open source technologies and advocating for their adoption, the authors of the whitepaper believe it can foster collaboration, standardisation and inclusivity in the development of eXperiential Technologies. The whitepaper emphasised that for XR Innovations, India needed to establish technology leadership and invest in education, research, development, and innovation aligning with the idea of moving beyond being solely a services player in the domain.

The report presents a gap analysis to assess XR skills in India, in line with global initiatives. Identifying gaps in hardware, software, and application skills helps outline a roadmap for skill development for the Government of India and for the policymakers.

With the exception of optics, there is moderate to high level of expertise in hardware. There is a modest prevalence of expertise in software, except in VR OS where skills are virtually non-existent. It is apparent that the XR community in the country is focused predominantly on applications with a large number lingering at basic levels of skill.

The vision is to move the practitioners up the value chain by focusing on advanced education, R&D and innovation. While the Hardware and Software components of XR are driven by R&D, XR ‘Application Development’ is devoid of research content.

The report also has proposed several initiatives for infrastructure and skill development in India: an XR-Superhighway, XR-Corridor, XR Innovation Centers, XR Skill Training Centers, XR Experience Spaces, XR Manufacturing Centers, and XR Education Centers.

Tile by jowl


He wouldn’t have noticed it if he weren’t a dentist. Being one, he spotted it right away — and wrote about it to The Washington Post. Our floor and wall tiles often come from materials that may have formed millions of years ago. A mirror-polish granite tile has many random features — we neither can make sense of them, or we do care to see what they are.

But a man, whose Reddit username is Kidipadeli75, said he was visiting his parents’ home in Europe when he spotted something odd in a floor tile. The travertine tile came from Denizli Basin of western Turkey. Travertine is a type of limestone that forms through the precipitation of minerals from mineral-rich water, typically in hot springs or limestone caves. It is a sedimentary rock composed primarily of calcium carbonate (CaCO3). The Denizli Basin was formed between 0.7 million and 1.8 million years ago. The feature that caught Kidipadeli75’s eye was a horseshoe shaped white material with some squarish shapes embedded in it. That was where Kidipadeli75’s expertise as a dentist came in handy. He instantly recognised it to be a mandible — lower jaw — of a man. The square shapes were remnants of his teeth.

The owner of the mandible and the teeth should have died at least 7,00,000 years ago. The lower jaw and teeth became part of rock. If the rock had not been sliced into tiles for homes, they would have probably been extracted and studied. But it was outlandish to file a dead man’s teeth in a floor tile of a home, thought Kidipadeli75. So, he wrote to WaPo.

How to make soft and squishy robots

How to make soft and squishy robots


For the majority who stand outside the robotics sector, our perceptions of robots are often inspired from science fiction narratives and cinematic portrayals — by the likes of Isaac Asimov with his visionary laws of robotics, to the iconic duo C3PO and R2D2, among countless others. Our collective imagination once painted robots in the anthropomorphic image, mirroring human form. However, today’s reality diverges significantly. Modern robots are specialised industrial tools, designed for precise tasks — be it a singular robotic limb or a complex assembly of mechanical armature and sensory equipment. The so-called humanoid robots of our era merely echo the basic human structure, equipped with a head, torso, limbs, and rudimentary sensory inputs akin to sight and sound.

But what about true human-like?

The major challenge to robots becoming more human-like is the skin and the sense of touch, and responses to it. The complexity of design in creating human-like skin for robots is enormous: considerations of texture, elasticity, and sensory capabilities — the physics of touch — is a challenge of balance between real and artificial.

Integrating human-like skin into robots can also be a software challenge, not just a hardware challenge. The human skin is a sensitive organ capable of detecting a wide range of tactile stimuli with precision. Replicating this level of sensory accuracy including pressure, temperature and texture can be challenging to integrate into robotic systems because of constraints around compatibility, space, and power requirements.

What the challenges with hardware and software mean to creating human-like robots is high-cost and low-scalability, as well as concerns of maintenance, hygiene, and durability.

But, a new research, from a team led by Kyungseo Park and Kazuki Shin, on “Low-Cost and Easy-to-Build Soft Robotic Skin for Safe and Contact-Rich Human–Robot Collaboration” has presented a novel solution — an easy-to-build soft robotic skin that could revolutionise how robots perceive and respond to human touch.

The groundbreaking paper from the IEEE Transactions on Robotics shows methods to employ air-pressure sensors and 3D-printed pads to provide a level of sensitivity and safety previously unattainable at a low cost.

The implications for industries like healthcare, personal robotics and any industries where robots and humans interact in a social setting are profound, potentially leading to robots that are not only safer but also more capable of complex social interactions with humans.

Why Soft Robotic Skin?

Traditional robots operate in structured environments where interactions with humans are minimal. However, as robots move into roles that require more direct contact with people — such as in homes, hospitals, or workplaces — the risk of accidental injuries increases. Hard exteriors can cause harm upon collision, making the integration of soft, sensitive materials essential for safety.

Giving robots a lifelike appearance and texture with the use of soft skin creates a more approachable and engaging presence. Imagine a robot that not only performs tasks efficiently but also looks and feels like a friendly companion, making the human feel more comfortable at vulnerable times.

The newly developed soft robotic skin addresses these concerns. It covers a robot’s hard surfaces with a layer that can sense pressure changes caused by physical contact. This skin is not only shock-absorbing but also capable of detecting and interpreting various types of touch, from gentle pats to firm presses. The technology is based on a network of air-filled pads made from thermoplastic urethane (TPU), a material chosen for its durability and flexibility.

One of the standout features of this technology is its simplicity and affordability. The skin can be produced using standard 3D printers and off-the-shelf sensors, making it accessible to a wide range of users—from industrial designers to academic researchers and hobbyists.

Each pad in the skin functions as an independent sensor, measuring changes in internal air pressure when deformed by contact. This data is then processed to distinguish between different types of interactions, like a steady push or a quick tap. These sensors are integrated into a system that utilizes the Robot Operating System (ROS), allowing for easy adoption and integration with existing robotic systems.

Is it good enough?

The research team demonstrated the effectiveness of their design with a custom robot equipped with the soft robotic skin. The robot could safely interact with humans in a controlled environment, responding to touch by adjusting its movements to avoid potential harm. This capability was showcased in scenarios where the robot had to navigate around human operators, adjusting its path in real-time to prevent collisions.

In addition to safety, the soft skin enhances a robot’s ability to perform tasks that require delicate handling, such as in assembly lines or when interacting with the elderly in caregiving scenarios.

While the current design offers significant improvements in safety and tactile response, the team acknowledges that further enhancements are needed. Future versions could feature improved spatial resolution, allowing for even finer distinctions between different types of touch. Additionally, integrating sensors that can detect temperature or texture could further enhance a robot’s perceptual capabilities.

Brightening up to fight climate change

Brightening up to fight climate change


Is climate change clouding your moods and you need some brightening up?

Scientists are experimenting with a wild idea to fight global warming — brightening up marine clouds by aerosol sprays so that they reflect more sunlight back into the atmosphere.

Really, the idea of using aerosol to reflect sunlight — geo-engineering — is geriatric. So is ‘cloud seeding’, which is a rainmaker, literally. And now, somebody has thought of combining the two for a “brilliant” effect.

But the Marine Cloud Brightening (MCB) programme of the Department of Atmospheric Sciences, University of Washington, USA, is somewhat different from conventional geo-engineering. Guess what they are spraying? Salt. Trillions of extremely tiny particles of sea salt sprayed into clouds increase the clouds’ density and reflective capacity.

Only, we don’t know by how much. There are specific regions of the ocean with clouds that could be more favourable for brightening in this way, though it is still uncertain how much brightening could be achieved in different regions, says MCB. If marine cloud brightening were ever to be used, which areas are brightened, and by how much, would determine how much climate cooling could be produced. Furthermore, we don’t know if there would be any negative side-effects. This uncertainty has attracted criticism from some quarters, especially from a formation called The Alliance for Just Deliberations on Solar Geoengineering. But MCB says it is only a scientific experiment.

Tailoring carton boxes to fit more, waste less

Tailoring carton boxes to fit more, waste less


Pretty often, when you order something online, something as small as a perfume or a bottle of shampoo, it comes in a huge package. Products ordered online are often shipped in oversized cartons. The size of the overall package is much larger than its contents. This is fine as a protection for the ordered goods, but too much packing material goes against sustainability.

Helping to combat this issue is the CASTN (Carton Set Optimisation) software created by the Fraunhofer Institute for Material Flow and Logistics (IML), which puts together the optimum order-to-carton combination for each customer’s order. Clever algorithms calculate the best carton utilisation based on the item and order structure.

With the help of this software, shipping companies can select the optimal carton set for each item and order structure, says a press release from Fraunhofer IML.

30% item, 70% air

The CASTN software functions using two algorithms — The first uses an approach to create different carton sets based on parameters such as the number of permitted cartons or the maximum and minimum dimensions. The second — a bin-packing algorithm — ensures that the orders are efficiently packed in the selected cartons. The aim of this is to minimise packaging volume and achieve the smallest possible overall volume. At the end of this process, the software assesses each carton in a set, checking how well the internal capacity is filled by the order inside. This information is fed back into the evolutionary algorithm, which uses each carton’s score to create new, better sets. This continues until no better volume utilisation can be achieved.

Lukas Lehmann, scientist at Fraunhofer IML, says that customers are often unaware of the volume utilisation of their packaging, which is often only around 30 per cent. “They have no idea how much air they send. This is what our software calculates,” says the researcher. Once optimisation is complete, the results are analysed together with the customer so that they can select the appropriate carton set, says Lehmann.

Several industry partners, each with their own online retail business, have already benefited from carton set optimisation and increased their volume utilisation by 35 to 45 per cent while also reducing the number of carton types used.

Long way to go

While the concept looks good, it may not suit India as the cartons cannot be customised to the requirements of the e-commerce market, says S Veeraragavan, Managing Director, Sri Srinivasa Cartons & Containers, a Puducherry-based carton box manufacturer. If the company has a large volume, the cartons can be customised, but presently, the items are packed mostly using padding materials, he added.

An official of a leading e-commerce giant agrees with Veeraraghavan, saying it is too complex to have customised cartons — there would be too much variety, compared with standardised cartons. So, for now at least, India is not ready for the Fraunhofer’s solution.
