A LAG-based framework to overcome the challenges of the sustainable vaccine supply chain: an integrated BWM–MARCOS approach

PurposeEach individual needs to be vaccinated to control the spread of the COVID-19 pandemic in the shortest possible time. However, the vaccine distribution with an already strained supply chain in low- and middle-income countries (LMICs) will not be effective enough to vaccinate all the population in stipulated time. The purpose of this paper is to show that there is a need to revolutionize the vaccine supply chain (VSC) by overcoming the challenges of sustainable vaccine distribution.Design/methodology/approachAn integrated lean, agile and green (LAG) framework is proposed to overcome the challenges of the sustainable vaccine supply chain (SVSC). A hybrid best worst method (BWM)–Measurement of Alternatives and Ranking According to COmpromise Solution (MARCOS) methodology is designed to analyze the challenges and solutions.FindingsThe analysis shows that vaccine wastage is the most critical challenge for SVSC, and the coordination among stakeholders is the most significant solution followed by effective management support.Social implicationsThe result of the analysis can help the health care organizations (HCOs) to manage the VSC. The effective vaccination in stipulated time will help control the further spread of the virus, which will result in the normalcy of business and availability of livelihood for millions of people.Originality/valueTo the best of the author's knowledge, this is the first study to explore sustainability in VSC by considering the environmental and social impact of vaccination. The LAG-based framework is also a new approach in VSC to find the solution for existing challenges.

FRET Based Biosensor: Principle Applications Recent Advances and Challenges.

Förster resonance energy transfer (FRET)-based biosensors are being fabricated for specific detection of biomolecules or changes in the microenvironment. FRET is a non-radiative transfer of energy from an excited donor fluorophore molecule to a nearby acceptor fluorophore molecule. In a FRET-based biosensor, the donor and acceptor molecules are typically fluorescent proteins or fluorescent nanomaterials such as quantum dots (QDs) or small molecules that are engineered to be in close proximity to each other. When the biomolecule of interest is present, it can cause a change in the distance between the donor and acceptor, leading to a change in the efficiency of FRET and a corresponding change in the fluorescence intensity of the acceptor. This change in fluorescence can be used to detect and quantify the biomolecule of interest. FRET-based biosensors have a wide range of applications, including in the fields of biochemistry, cell biology, and drug discovery. This review article provides a substantial approach on the FRET-based biosensor, principle, applications such as point-of-need diagnosis, wearable, single molecular FRET (smFRET), hard water, ions, pH, tissue-based sensors, immunosensors, and aptasensor. Recent advances such as artificial intelligence (AI) and Internet of Things (IoT) are used for this type of sensor and challenges.

Blockchain technology and vaccine supply chain: Exploration and analysis of the adoption barriers in the Indian context

The vaccine distribution system, being a bio-pharmaceutical cold chain, is a complicated and sensitive system that must be effectively managed and maintained due to its direct impact on public health. However, vaccine supply chains continue to be affected by concerns, including vaccine expiry, inclusion of counterfeit vaccines, and vaccine record fraud. The blockchain technology integrated with the Internet of Things (IoT) can create a solution for global vaccine distributions with improved trust, transparency, traceability, and data management, which will help monitor the cold chain, tackle counterfeit drugs, surveillance, and waste management. Several theoretical models for vaccine management with blockchain have recently been published, and a few pilot studies for COVID-19 vaccine management using blockchain have been started in India. Still, full-scale adoption of blockchain technology in vaccine distribution and management has yet to be achieved due to underlying barriers. This study explores the adoption barriers utilizing Technology-Organization-Environment (TOE) framework with the help of extant literature and inputs from administrators, academics, immunization, and blockchain experts and then analyzed using the Delphi and fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) techniques. The finding shows that the requirement of change in organization structure and policies is the most prominent barrier, and the barrier related to requirement of large-scale IoT infrastructure and lack of technical expertise are the most impactful barriers. The theoretical contribution of this study lies in the identification and analysis of barriers that should be addressed to achieve blockchain technology adoption in the vaccine supply chain.

Recent advances in copper and copper-derived materials for antimicrobial resistance and infection control.

Antibacterial properties of copper have been known for ages. With the rise of antimicrobial resistance (AMR), hospital-acquired infections, and the current SARS-CoV-2 pandemic, copper and copper-derived materials are being widely researched for healthcare ranging from therapeutics to advanced wound dressing to medical devices. We cover current research that highlights the potential uses of metallic and ionic copper, copper alloys, copper nanostructures, and copper composites as antibacterial, antifungal, and antiviral agents, including those against the SARS-CoV-2 virus. The applications of copper-enabled engineered materials in medical devices, wound dressings, personal protective equipment, and self-cleaning surfaces are discussed. We emphasize the potential of copper and copper-derived materials in combating AMR and efficiently reducing infections in clinical settings.

Banning Loose Cigarettes and Other Tobacco Products in India: A Policy Analysis.

BACKGROUND: Sale of single cigarettes (also known as singles or loosies) is a key driver for early initiation of smoking and is a leading contributor to the smoking epidemic in India. Sale of singles additionally deter implementation of tobacco control strategies of pictorial health warnings including plain packaging and defeat effective taxation and promote illicit trade. We review India's tobacco control policy responses towards banning singles and other products sold as loose tobacco and identify opportunities for future policy intervention especially in the context of the ongoing COVID-19 pandemic. METHODS: Existing national and sub-national policy documents were analyzed for their content since the inception of the tobacco control laws in the country. RESULTS: There are no effective provisions at national level to ban loose tobacco products in India. However, the implementation of multiple legislative and regulatory measures (Acts/circulars/letters/notifications/orders/court judgements) in 16 Indian states and jurisdictions provide sufficient legal framework to substantiate its complete ban pan India. While the majority of state governments have adopted state level measures, Rajasthan had issued specific directive to all the 33 districts banning loose cigarettes and other tobacco products. Himachal Pradesh introduced the most unique and comprehensive legislation, for banning the sale of cigarettes and beedis (Dated November 7, 2016). The most recent notification in the state of Maharashtra (September 24, 2020) is the first to leverage powers using a mix of national and state legislations including the legislation addressing the rapidly emerging challenge of managing COVID-19. CONCLUSION: A robust national policy which supports strong provision to deter tobacco companies, their distribution network and vendors from selling singles or loose tobacco products is urgently needed. Such policy should be backed by cautionary messaging for consumers as well. Eliminating singles and loose tobacco sale will help in blunting tobacco use prevalence besides curbing spread of infectious diseases like COVID-19 pandemic.

Impact of COVID-19 on orthopaedic residents-an Indian perspective.

OBJECTIVES: The COVID-19 pandemic is a public health emergency causing a deleterious effect on the health system. It affected all the specialties and subspecialties in the medical field causing havoc in the health institutions. This pandemic affected both orthopaedic consultants and the residents who are under training. Our purpose was to study the impact of COVID-19 on orthopaedic residents in their professional life. METHOD: The study design was a computer-based digital online survey of the orthopaedic residents in India. The survey had 15 questions with multiple options related to the effect of COVID-19 on their orthopedic department, effect on teaching, surgical exposure, hands-on surgeries, the effect on workload, effect on mental stress, exposure to arthroplasty, arthroscopic surgeries, spine surgeries, and deformity correction surgeries. RESULTS: Elective surgeries stopped in 91% of the hospitals, academic teaching stopped in 98% of the institutions. Eighty-six percent of the residents are not getting adequate surgical exposure, 73% of the residents are getting negligible hands-on surgical training. Residents are mentally stressed related to academic examinations, academic training, and also because of COVID 19 duties. Residents are getting the least exposure in subspecialties like arthroplasty, arthroscopy, and spine. CONCLUSION: The COVID-19 pandemic not only affected the orthopaedic consultants but also the orthopaedic residents to a great extent as residents are the backbone of any department/institution. The pandemic affected significantly resident's academic teaching, surgical exposure, hands-on training and mental stress related to COVID duties, academic training disturbance, and also academic examinations.

Smokeless tobacco control in India: policy review and lessons for high-burden countries.

We examined the magnitude of smokeless tobacco (SLT) use in India and identified policy gaps to ascertain the priorities for SLT control in India and other high SLT burden countries in the Southeast Asia region. We reviewed and analysed the legal and policy framework to identify policy gaps, options and priority areas to address the SLT burden in India and lessons thereof. In India, 21.4% adults, including 29.6% of men, 12.8% of women, use SLT while more than 0.35 million Indians die every year due to SLT use. SLT use remains a huge public health concern for other countries in the region as well. Priority areas for SLT control should include: constant monitoring, increasing taxes and price of SLT products, strengthening and strict enforcement of existing laws, integration of SLT cessation with all health and development programmes, banning of advertisement and promotion of SLT, increasing age of access to tobacco up to 21 years, introducing licensing for the sale of SLT, standardising of SLT packaging and preventing SLT industry interference in the implementation of SLT control policies besides a committed multistakeholder approach for effective policy formulation and enforcement. SLT control in India and the other high SLT burden countries, especially in the Southeast Asia region, should focus on strengthening and implementing the above policy priorities.
