Emerging Trends in Lipid-Based Vaccine Delivery: A Special Focus on Developmental Strategies, Fabrication Methods, and Applications.

Lipid-based vaccine delivery systems such as the conventional liposomes, virosomes, bilosomes, vesosomes, pH-fusogenic liposomes, transferosomes, immuno-liposomes, ethosomes, and lipid nanoparticles have gained a remarkable interest in vaccine delivery due to their ability to render antigens in vesicular structures, that in turn prevents its enzymatic degradation in vivo. The particulate form of lipid-based nanocarriers confers immunostimulatory potential, making them ideal antigen carriers. Facilitation in the uptake of antigen-loaded nanocarriers, by the antigen-presenting cells and its subsequent presentation through the major histocompatibility complex molecules, leads to the activation of a cascade of immune responses. Further, such nanocarriers can be tailored to achieve the desired characteristics such as charge, size, size distribution, entrapment, and site-specificity through modifications in the composition of lipids and the selection of the appropriate method of preparation. This ultimately adds to its versatility as an effective vaccine delivery carrier. The current review focuses on the various lipid-based carriers that have been investigated to date as potential vaccine delivery systems, the factors that affect their efficacy, and their various methods of preparation. The emerging trends in lipid-based mRNA vaccines and lipid-based DNA vaccines have also been summarized.

Airway management, procedural data, and in-hospital mortality records of patients undergoing surgery for mucormycosis associated with coronavirus disease (COVID-19).

PURPOSE: Although unexpected airway difficulties are reported in patients with mucormycosis, the literature on airway management in patients with mucormycosis associated with Coronavirus disease is sparse. METHODS: In this retrospective case record review of 57 patients who underwent surgery for mucormycosis associated with coronavirus disease, we aimed to evaluate the demographics, airway management, procedural data, and in-hospital mortality records. RESULTS: Forty-one (71.9%) patients had a diagnosis of sino-nasal mucormycosis, fourteen (24.6%) patients had a diagnosis of rhino-orbital mucormycosis, and 2 (3.5%) patients had a diagnosis of palatal mucormycosis. A total of 44 (77.2%) patients had co-morbidities. The most common co-morbidities were diabetes mellitus in 42 (73.6%) patients, followed by hypertension in 21 (36.8%) patients, and acute kidney injury in 14 (28.1%) patients. We used the intubation difficulty scale score to assess intubating conditions. Intubation was easy to slightly difficult in 53 (92.9%) patients. In our study, mortality occurred in 7 (12.3%) patients. The median (range) mortality time was 60 (27-74) days. The median (range) time to hospital discharge was 53.5 (10-85) days. The median [interquartile range] age of discharged versus expired patients was 47.5 [41,57.5] versus 64 [47,70] years (P = 0.04), and median (interquartile range) D-dimer levels in discharged versus expired patients was 364 [213, 638] versus 2448 [408,3301] ng/mL (P = 0.03). CONCLUSION: In patients undergoing surgery for mucormycosis associated with the coronavirus disease, airway management was easy to slightly difficult in most patients. Perioperative complications can be minimized by taking timely and precautionary measures.

The COVID-19 pandemic: a new epoch and fresh challenges for cancer patients and caregivers-a descriptive cross-sectional study.

PURPOSE: Cancer patients and their caregivers are overwhelmed with features of uncertainty, fear, shock, worry, anxiety, sadness, and grief. To add on to their misery, the COVID-19 pandemic has severely afflicted the cancer care delivery. The study was conducted to observe the challenges faced by cancer patients and their caregivers and to formulate strategies for oncological setups to overcome those challenges. METHODS: After obtaining institutional ethical clearance, a descriptive cross-sectional study was conducted to observe the challenges faced by patients and their caregivers at the level of various domains (physical, logistic, psychological, socioeconomic, and spiritual) who visited the outpatient and inpatient department of cancer pain and palliative care unit. The results were expressed in absolute numbers. RESULTS: Major challenges encountered were suffering from physical symptoms like pain, nausea, vomiting, dyspnea (90%), postponement of cancer treatment (80%), fear of contracting COVID infection due to hospital visit (93.5%), lack of accommodation (70%), and lack of spiritual clarity and hope (50%). CONCLUSIONS: Major challenges faced by patients were in physical and psychological domains, and those by caregivers were in socioeconomic domains and handling physical symptoms of their patients. It is imperative to recognize and be cognizant of the challenges faced by cancer patients and their caregivers. Health care setups should formulate strategies to alleviate these challenges and provide holistic care to cancer patients. These strategies will hold in good stead for future pandemics also.

A Questionnaire-based Survey on Challenges Faced and Strategies Adopted by Pain and Palliative Care Physicians Working in Oncology Setup During Novel COVID-19 Pandemic - A Descriptive Cross-sectional Study.

OBJECTIVES: Novel coronavirus (COVID-19) pandemic has brought to the fore various challenges faced by pain and palliative care physicians working in oncology setup all over the country. Cancer care has been afflicted a lot during the pandemic, with challenges faced by patients and their caregivers as well as the healthcare workers. The questionnaire based online survey was conducted to explore the personal challenges faced, strategies adopted and to compare the challenges between different oncology setups. MATERIALS AND METHODS: After obtaining institutional ethical clearance the online questionnaire prepared through Google forms was rolled out to pain and palliative care physicians working all over the country with the help of social media platforms. The results were expressed in absolute number, percentage and comparisons were made with the help of Fisher's exact test. RESULTS: Maximum challenges faced were the fear of carrying infection back home (91%), the possibility of attending to a COVID positive case in day to day clinical practice because of inadequate space and screening (62%) and limited services provided by NGO's during pandemic (71%). Strategies commonly adopted were the provision of necessary personal protective equipment (83%), the conduct of educational sessions for the task force members (67%), maximum utilization of available space in the hospital (85%) and stockpiling of necessary medications and equipment (75%). CONCLUSION: It is the need of the hour to formulate strong and effective strategies to overcome the challenges encountered by pain and palliative care physicians so that we are equipped in the future to deal with any kind of pandemics.

Rendezvous of Cancer Patients with Logistic and Socioeconomic Challenges during COVID-19 Pandemic: A Case Series.

The coronavirus disease 2019 pandemic has shaken the health-care infrastructure worldwide and has led to enormous challenges for cancer patients. They are suffering on various fronts during this pandemic, especially the often overlooked ones such as logistic and socioeconomic. Through the case series, we have highlighted the various components of these challenges the cancer patients are facing and tried to emphasize that the health-care setups and government along with nongovernmental organizations have to come on the forefront to help the patients mitigate these challenges.

Unraveling the Role of Palliative Surgery in the Era of COVID-19 Pandemic.

Palliative surgery forms an important pillar of palliative treatment to provide holistic care to cancer patients in the form of providing relief from pain, local control of disease, hemorrhage, and for the purpose of rehabilitation. During the COVID-19 pandemic, we report the successful management of two cases of colorectal cancer which came under the category of high priority and underwent palliative surgery to provide relief from pain.
