Socio-Economic and Health Consequences of COVID-19 on Indian Migrants: A Landscape Analysis.

The COVID-19 pandemic has hugely affected the world and human lives, the economy, and lifestyles. The pandemic control measures, such as lockdowns, forced many people to migrate from their destination to their source in various states, leading to increased vulnerability of migrants. The present review aimed to explore the different health, economic, and social impacts on internal migrants of India during the pandemic. The publications on internal migration and COVID-19 from India were retrieved from PubMed and Google Scholar using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 159 articles were extracted, of which 28 were reviewed. The articles published after March 1, 2020, were included in the review, irrespective of the design. Out of 28 articles, only half were original studies; the rest were either perspective, opinion, and review studies or editorial and commentary papers. Depression, anxiety, and stress due to job loss and lockdown were the major health issues documented. There was livelihood disturbance due to loss of income, such as inability to pay rent, loans, borrowing from relatives, and fear of its consequences. The migrants also faced stigma and discrimination from the villagers. The review also highlighted that although the government implemented various schemes to help the migrants, the majority were left out due to the non-availability of identity proof and ration cards. The safeguarding measures for these unregistered migrants must be facilitated to access health, economic, and social protection. Although various publications have focused on the mental health of the migrants, the socio-ecological aspects have been least explored, which calls for further studies. The literature on the impact of COVID-19 on other vulnerable populations like women and children and access to healthcare services is also scant, which needs to be explored further.

Dissecting WASH Assessment Tools and Recommending a Comprehensive Tool for Indian Healthcare Facilities.

Providing adequate Water Sanitation and Hygiene (WASH) in Health Care Facilities (HCFs) has many benefits, including achieving Sustainable Development Goals (SDGs) and Universal Health Coverage (UHC). However, there is a significant shortage of statistics on the status of WASH in Healthcare Facilities (WinHCF), resulting in roadblocks in developing improvement strategies. Further, there is a lack of detailed comparison of WASH components covered in available tools against the standards. The present study aims to dissect the national and international tools for WASH assessment in HCFs to suggest comprehensive WASH indicators. The databases like PubMed, Scopus, ScopeMed, Cochrane and Google Scholar were used to extract the available tools. The assessment process, methodology, and components of national and various international tools were compared and synthesized. A total of seven tools, namely WASH FIT 2, Facet, SARA, SPA, TOOL BOX-II, CDC and Kayakalp, were compared on eight components: water, sanitation, hand hygiene, healthcare waste, environmental cleaning and hygiene, infrastructure, workforce management, policy and protocols. Although most tools have covered the same indicators, the methodology and definitions differ. Few of the tools fail to capture the basic indicators defined by Joint Monitoring Programme (JMP). The critical indicators of policy and protocols are only covered in WASH FIT 2, Kayakalp, and TOOL BOX-II. Likewise, most tools fail to capture the indicator of cleaning, IPC practices and climate resilience. The present review also highlighted the limitations of selected tools regarding definitions, methodology and implementation. Hence, based on the review findings, a comprehensive short tool has been developed to monitor WASH in HCF of India. It comprises all the essential fundamental indicators identified from various tools, and recommended by the JMP service ladder with proper definitions. This tool can be helpful for hospital staff and managers for the routine monitoring of WASH in HCFs and improve the quality of care and IPC practices in HCFs.

Challenges and Motivators to Organ Donation: A Qualitative Exploratory Study in Gujarat, India.

Purpose: Despite the global efforts to improve organ donation, there is a demand-supply gap for organs in India. The only solution to meet this disparity is to improve deceased donor transplants in the country through victims of road accidents. The government has instituted several initiatives to achieve this goal. However, challenges and barriers continue to affect the organ donation process. The present study aims to document the motivating factors and obstacles in the decision of families to donate organs in Ahmedabad, Gujarat and their suggestions to improve the processes involved in organ donation. Patients and Methods: A qualitative exploratory study (in-depth interview) of ten relatives of deceased organ donors was conducted from Oct 2021 to Feb 2022. Interviews were audio recorded, and detailed notes were taken during the interview. Thematic analysis was done using ATLAS.ti version 8 software. Results: The significant motivators identified were family members' belief or conviction that it would help save the lives of others; a sense of moral obligation to do so as bodies of brain-dead persons can contribute to this noble goal, no use of the body after death, an extension of life, and being a role model for others. The challenges were mistrusting the organ donation process, fear of being responsible for any mishappening, and feeling of shock. The suggestions to improve organ donation included awareness creation, simplifying the legal process for accidental deaths, providing benefits to the donor family, and a system for identifying potential donors and their counselling. Conclusion: The present study reflects the need for a more comprehensive awareness campaign to generate awareness and remove the misconception about organ donation in India. The findings of the study can be helpful for policymakers to amend the current organ donation process in India and improve the disequilibrium of demand and supply of deceased donations in India.

Complexity of Decision-Making!: Case Studies of Cadaveric Organ Donations in Ahmedabad, India.

Background: The disequilibrium in the demand-supply nexus of organ donation prevails an urgent need for understanding the process and cascade of the donation. There is a lack of evidence in organ donation literature within India that focuses on factors influencing familial consent, the decision-making process, and psychosocial factors that can predict successful organ donation. Such evidence can assist in designing interventions and policy dialogue focusing on the discussion on enhancing donation decisions with relatives. Thus, the present study is an effort to document the decision-making complexity systematically among successful cadaveric organ donation cases. Methods: A qualitative exploratory, including the network assessment was implemented between October 2021 and February 2022 in one of the western states of India, Gujarat. A semi-structured interview guide that was comprised of thematic, open-ended questions focused on understanding the network for the decision-making process was prepared, and trained interviewers conducted the interview at the suitable place of the donor's relative. Results: The 10 interviews among the closest relatives of the deceased were conducted and the decision-making process indicated the involvement of multiple actors. The social network analysis reveals a minimum node of 2 to 7, with the highest ties of 22. The maximal degree was 3.6, and the density of 1 of these networks. Out of 10, in most cases, the ties were more than 2, with a maximum of 22 ties, which shows that more people communicated to each other before the final decision-making. Conclusion: The analysis indicates that the decision-making for deceased organ donation is a complex process as in most cases, multiple family members were involved and interaction happened before the final decision-making. The study explains the decision-making during the cadaveric organ donation process by exploring families' experiences. Further research is recommended to generate evidence on the factors and the family dynamics, including the complexity of successful organ donation.

Predictors for mucormycosis in COVID era: A case-control study from Gujarat.

Context: Mucormycosis has been increasingly described in the coronavirus disease (COVID-19) era, however, there is a lack of robust epidemiological studies to understand the predictors for the development of mucormycosis from India. Aims: To document the risk factors of mucormycosis with or without COVID-19 and estimate the strength of association of various risk factors. Settings and Design: A case-control study was conducted in the Ahmedabad districts of Gujarat from June to August 2021. Methods and Material: One hundred participants (25 cases with mucor, 75 without mucor) were enrolled in the study. The cases and controls were then matched based on age and gender. Ethical approval was sought from the Institutional Ethics Committee of the Indian Institute of Public Health Gandhinagar, Gujrat, India. Statistical Analysis Used: Data were collected using the Epi Collect 5 application, and the descriptive, inferential analysis was done using the SPSS version 21 statistical software. Results: About 68% of the cases were from a rural area and had past comorbidity conditions. About 80% of the cases reported a previous history of COVID-19, whereas 67% of the controls reported the same. The factors which remained significant after applying the hierarchical model were rural residents (OR = 3.2 [95% CI: 1.05-10.3]) and history of oxygen therapy (OR = 5.42 [95% CI: 1.24-23.8]). Conclusions: This study concludes that mucormycosis is independent of the COVID-19 status. Rural residents and oxygen therapy were found to be the most significant risk factors for mucormycosis. The findings of this study are also not conclusive to establish an association; thus, further exploration and in-depth research with larger samples are recommended.

Evidence of Antimicrobial Resistance from Maternity Units and Labor Rooms: A Water, Sanitation, and Hygiene (WASH) Study from Gujarat, India.

The main objective of this study was to determine the microbial contamination and antimicrobial resistance pattern among isolated bacteria from the environment surfaces of maternity units and labor rooms of healthcare facilities in the Gujarat state of India. The cross-sectional study was conducted in ten healthcare facilities, where the microbiological swab samples were collected from various pre-decided environmental surfaces of the maternity and labor rooms as part of the Water, Sanitation and Hygiene (WASH) assessment. The swabs were analyzed by conventional microbiological culture methods to identify microorganisms, including antimicrobial susceptibility testing. The study provides an insight into the microbial contamination of the visibly clean areas, i.e., the maternity ward, labor room, and general wards of the healthcare facilities. The labor rooms were found to be highly contaminated in comparison to other selected sites. The microbiological findings revealed a predominance of Gram-negative bacteria, specifically Pseudomonas species. The antibiotic susceptibility testing indicates resistance against many commonly used antibiotics. This study produces an identified necessity for enhancing microbiological surveillance in labor rooms and maternity units. This study also highlights the importance of microbiological status along with the WASH status of healthcare facilities.

Challenges in the execution of public health research: Reflections from Public Health Research Initiative (PHRI) grant management in India.

Background: Well-planned health research is fundamental to the success of any public health system in leading to better population health outcomes. Although the Indian public health system is unique, it lacks strong linkages between research and practice. There is a pressing need to address the gap in the research to reduce the disease burden in the country. Although various efforts are made to enhance public health research, such research is rarely documented as a process. The objective of the present paper is to document issues and challenges in managing public health research grants awarded to the PHRI fellows from 2013-to 2021 under the PHRI project. Method: A mixed-method approach, including qualitative (in-depth) interviews and secondary review, was adopted to collect the challenges in executing PHRI grants (during 2013-2021). The in-depth interviews were conducted among the PHRI execution team, whereas the secondary document review was conducted among the PHRI fellows, and the findings are documented under major themes like administrative, technical, and financial issues and/or challenges. Result: A total of 35 candidates 16 intramural (IM) candidates affiliated with PHFI or IIPH institutes and 19 extramural (EM) candidates affiliated to other academic institutes were selected for the fellowship, The common challenges identified amongst intra & extramural fellows were inability to disseminate the study findings, challenges in communication and getting audited statements, changes in study methods without prior permission, mid study attrition of CO-PIs and high budget utilization. The specific difficulties identified from extramural fellows were change in institute affiliation, lack of support to fund utilization from the parent institute and difficulties in field validation. Conclusion: The present perspective emphasizes that the management and implementation of a research grant is the crucial part of achieving a project's desired outcome. The learnings of PHRI grant execution allows the researchers to understand the issues in terms of methodological rigour and financial guidelines, rigorous tracking of the project activities, and complying with the terms of funding agreement are crucial. The challenges explored in this grant execution recommend developing a structured public health grant management leadership program for researchers and executors.

Breast Cancer Transcriptional Regulatory Network Reprogramming by using the CRISPR/Cas9 System: An Oncogenetics Perspective.

Breast cancer (BC) is the second most commonly diagnosed cancer in the world. BC develops due to dysregulation of transcriptional profiles, substantial interpatient variations, genetic mutations, and dysregulation of signaling pathways in breast cells. These events are regulated by many genes such as BRCA1/2, PTEN, TP53, mTOR, TERT, AKT, PI3K and others genes. Treatment options for BC remain a hurdle, which warrants a comprehensive understanding that establishes an interlinking connection between these genes in BC tumorigenesis. Consequently, there is an increasing demand for alternative treatment approaches and the design of more effective treatments. In this regard, it is crucial to build the corresponding transcriptional regulatory networks governing BC by using advanced genetic tools and techniques. In the past, several molecular editing technologies have been used to edit genes with several limitations. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR Associated Protein 9 (CRISPR/Cas9) recently received wise attention due to its potential in biomedical and therapeutic applications. Here, we review the role of various molecular signalling pathways dysregulated in BC development such as PTEN/PI3K/AKT/mTOR as well as BRCA1/BRCA2/TP53/TERT and their interplay between the related gene networks in BC initiation, progression and development of resistance against available targeted therapeutic agents. Use of CRISPR/Cas9 gene-editing technology to generate BC gene-specific transgenic cell lines and animal models to decipher their role and interactions with other gene products has been employed successfully. Moreover, the significance of using CRISPR/Cas9 technology to develop early BC diagnostic tools and treatments is discussed here.

Contributing Factors in the Tuberculosis Care Cascade in India: A Systematic Literature Review.

Tuberculosis (TB) care cascade is a recently evolved care model for patient retention across the sequential stages of care for a successful treatment outcome. The care cascade is multi-folded and complex in setting where the health system is reforming for its resilience. India, one of the countries with the highest burden of tuberculosis mortality and morbidity, is not an exception to this complexity. With the diverse challenges in the Indian health system and societal diversity, it is essential to understand the factors contributing to this TB care cascade. Thus, this study aims to map all the contributing factors to the TB care cascade in India. Further, it also captures the different patterns of factors explored so far in different countries' regions. This systematic literature review was conducted between October 2020 and February 2021 in India using PubMed databases, Web of Science, and Google Scholar. Two reviewers extracted the data from eligible studies to summarize and tabulate important findings. Data were extracted and tabulated for study design, location of the study, type of TB patients, methodological approach, system side challenges, and demand-side challenges in the study's findings. Out of 692 initial hits from the literature search, 28 studies were finally included to synthesize evidence in this review as per the inclusion and exclusion criteria. This review provides an insight into different factors such as the system-side (health workforce, institutional) and the demand-side (individual, societal) contributing towards the care cascade. The prime factors reflected in most of the studies were socio-economic condition, disease awareness, myths/beliefs, addictions among the demand-side factors and accessibility, the attitude of the healthcare staff, delay in referral for diagnosis among the system-side factors. The accountability for addressing these diverse factors is recommended to close the gaps in the TB care cascade.

3D Modeling of Epithelial Tumors-The Synergy between Materials Engineering, 3D Bioprinting, High-Content Imaging, and Nanotechnology.

The current statistics on cancer show that 90% of all human cancers originate from epithelial cells. Breast and prostate cancer are examples of common tumors of epithelial origin that would benefit from improved drug treatment strategies. About 90% of preclinically approved drugs fail in clinical trials, partially due to the use of too simplified in vitro models and a lack of mimicking the tumor microenvironment in drug efficacy testing. This review focuses on the origin and mechanism of epithelial cancers, followed by experimental models designed to recapitulate the epithelial cancer structure and microenvironment, such as 2D and 3D cell culture models and animal models. A specific focus is put on novel technologies for cell culture of spheroids, organoids, and 3D-printed tissue-like models utilizing biomaterials of natural or synthetic origins. Further emphasis is laid on high-content imaging technologies that are used in the field to visualize in vitro models and their morphology. The associated technological advancements and challenges are also discussed. Finally, the review gives an insight into the potential of exploiting nanotechnological approaches in epithelial cancer research both as tools in tumor modeling and how they can be utilized for the development of nanotherapeutics.

Visually clean is not necessarily microbiologically safe: Learnings from WASH assessment of maternity units of Gujarat, India.

BACKGROUND AND AIMS: Water Sanitation and Hygiene (WASH) within the context of Sustainable Development Goal (SDG) is well debated; however, WASH in health care sector is still in nascent phase, especially for maternity units. Although there are studies on WASH in maternity units, least are focused towards the microbiological safety. The objective of present study is to compare the visual assessment with microbiological assessment of selected maternity units of Gujarat (India) and to document microbiological contamination and drug resistance. METHODS: A cross-sectional study was carried out in 10 selected maternity units of Sabarkantha and Gandhinagar district of Gujarat, India, during Feb-March 2018. Two steps of Tool Box Plus were used for documentation: visual and microbiological assessment. Antimicrobial Resistance (AMR) patterns amongst positive microorganisms were also documented. RESULTS: Although the majority of the studied maternity units were visually clean, the microbiological findings contraindicated the same. The overall visual score across all facilities was close to 50% indicating good visual cleanliness. Out of 195 samples collected, 18% (35) samples were positive for pathogenic organisms and the majority were identified from mops and labour table. 1/3rd of organisms were resistant to > 5 antibiotics. Pathogenic organism identified includes Acitenobacter, Klebsilla, MR CONS, E coli, Psudomonas Aeruginosa and Pseudomonas species. CONCLUSIONS: Visual assessment alone which is currently used for assessment of hygiene is not a proxy for safety. It should be validated by the microbiological method. Microbiology surveillance should be explored to get valuable insights on the effectiveness of cleaning practices of the maternity units.

Assessment of water, sanitation and hygiene in HCFs: which tool to follow?

Water, sanitation and hygiene (WASH) is important to improve and maintain the quality of health care services. Improving and managing WASH services require strong and consistent monitoring mechanisms to measure progress and direct efforts where needs are greatest. Although several tools are available to assess WASH in health care facilities (HCFs), there is always a dilemma among the program managers to select an appropriate tool for the assessment of WASH. Thus, it was aimed to perform a descriptive review of all available WASH assessment tools and assist in reaching a consensus for an optimal tool to assess WASH in HCFs. For this descriptive review, PubMed, ScopeMed and Google Scholar were used to search all available tools for the assessment of WASH. All the tools available online since 1991 till July 2018 were included in the review. Globally, nine different WASH assessment tools were retrieved. The majority of them have their self-limitations on the basis of 11 selected indicators and were examined in all the retrieved tools. There are variability and overlapping components within the specific tools. Very few survey instruments including human resource (HR), supply, budget, patient/staff satisfaction and documentation for appropriateness of WASH were found to be neglected. The majority of instruments were based on the subjective assessment of WASH validating with microbiological surveillance and photo documentation. The descriptive review suggests that various tools are available for the assessment of WASH but none of them seem to be complete with all indicators and to have consensus for the elements. Therefore, there is a need to develop a robust and comprehensive tool for the assessment of WASH in HCFs.

A cohort study on risk factors for preterm births in rural Gujarat.

BACKGROUND: Prematurity is one of the leading causes of neonatal and under-five mortalities globally and also in India. It is an important determinant of short- and long-term morbidities in infants and children. Unfortunately, risk factors of majority of preterm births (PTBs) remain unexplained which calls for appropriate action. There is a dearth of community-based research on PTB and its risk factors, especially in high burden countries like India. OBJECTIVES: The objective of the study was to explore different risk factors for PTB. METHODS:: A cohort of 1977 antenatal mothers was enrolled at household level by trained field investigators and was followed up in four districts of Gujarat, India, to document the outcome of pregnancy. Pretested and structured questionnaires were used to collect information. A hierarchical regression model was used to analyze the risk factors for PTB. RESULTS: Proportion of PTB was 9% among the enrolled cohort. Risk factors which were found to be significant on applying the hierarchical model were periodontal disease, long sleep duration, and sex during any trimester. CONCLUSIONS: The study suggests an urgent need for strengthening of existing guidelines for effective, evidence-based, and culturally appropriate interventions for prevention of PTB. Maintenance of good oral hygiene should find a place in routine recommendations for pregnant women, and antenatal examinations should include screening for oral hygiene also.

Synthesis of xylan carbonates - An approach towards reactive polysaccharide derivatives showing self-assembling into nanoparticles.

Xylan phenyl carbonate (XPC) derivatives were prepared and characterized comprehensively. By conversion of xylan with phenyl chloroformate either in dipolar aprotic solvents with LiCl or in an ionic liquid, XPC with degrees of substitution (DS) of up to 2.0, i.e., fully functionalized derivatives, could be obtained. The synthesis was studied with respect to the influence of different reaction parameters. It was found that the reaction medium as well as the type of starting xylan strongly affected the efficiency of the derivatization. The derivatives obtained were characterized by FT-IR- and NMR spectroscopy. Surprisingly, it was found that C-3 is the most reactive position in this particular reaction while substitution in position C-2 only occurred if the neighboring position C-3 already carried a phenyl carbonate group. XPC were found to form spherical nanoparticles (NP) of well-defined shape with diameters around 158 nm. These materials possess unique potential as activated NP for advanced applications.

Chitosan-Cellulose Multifunctional Hydrogel Beads: Design, Characterization and Evaluation of Cytocompatibility with Breast Adenocarcinoma and Osteoblast Cells.

Cytocompatible polysaccharide-based functional scaffolds are potential extracellular matrix candidates for soft and hard tissue engineering. This paper describes a facile approach to design cytocompatible, non-toxic, and multifunctional chitosan-cellulose based hydrogel beads utilising polysaccharide dissolution in sodium hydroxide-urea-water solvent system and coagulation under three different acidic conditions, namely 2 M acetic acid, 2 M hydrochloric acid, and 2 M sulfuric acid. The effect of coagulating medium on the final chemical composition of the hydrogel beads is investigated by spectroscopic techniques (ATR-FTIR, Raman, NMR), and elemental analysis. The beads coagulated in 2 M acetic acid displayed an unchanged chitosan composition with free amino groups, while the beads coagulated in 2 M hydrochloric and sulfuric acid showed protonation of amino groups and ionic interaction with the counterions. The ultrastructural morphological study of lyophilized beads showed that increased chitosan content enhanced the porosity of the hydrogel beads. Furthermore, cytocompatibility evaluation of the hydrogel beads with human breast adenocarcinoma cells (soft tissue) showed that the beads coagulated in 2 M acetic acid are the most suitable for this type of cells in comparison to other coagulating systems. The acetic acid fabricated hydrogel beads also support osteoblast growth and adhesion over 192 h. Thus, in future, these hydrogel beads can be tested in the in vitro studies related to breast cancer and for bone regeneration.

Improving Adolescent Health: Learnings from an Interventional Study in Gujarat, India.

BACKGROUND: There are multiple risk factors during adolescence, which become precursors of various diseases and injuries inflicting high morbidity, mortality, and disability. There are several gaps in adolescent health research in India; one among them is that programs targeting adolescent health are constrained by the absence of rigorous interventional research informing interventions for improving adolescent health. This study aims to document the effectiveness of intervention on adolescent health and knowledge change on the risk factors among adolescents in one of the selected districts in Gujarat, India. METHODS: This was an interventional study with quasi-experimental design executed in one of the blocks of Gujarat. Baseline was conducted in 2013-2014 followed by intervention and the end line during 2016-2017. A structured validated questionnaire after pilot testing was executed to collect information on sociodemographic profile, nutrition status, menstrual hygiene practices, reproductive and sexual health, substance abuse, program awareness and utilization, and empowerment through life skills of adolescents in baseline and end line survey. Data analysis was carried out using IBM SPSS Statistics for Windows, Version 20.0. (Armonk, NY: IBM Corp). RESULTS: This study documented increased awareness regarding anemia, knowledge about STD and HIV/AIDS, reduced addiction to tobacco, improved practices during menstrual hygiene and engagement with adolescent services/schemes in the intervention site. CONCLUSION: This study concludes that evidence-based interventions lead to increase in knowledge and practices; however, some improvements have also been documented in the nonintervention site. Therefore, changes due to interventions could not be attributed completely for improving adolescent health. Further long term interventional studies are required to develop a robust evidence on improving health of adolescents in India.

Convergence and Outreach for Successful Implementation of Rashtriya Kishor Swasthya Karyakram.

BACKGROUND: Adolescents (10-19 years of age) constitute about one-fifth of India's population. The Ministry of Health and Family Welfare, Government of India, has launched Rashtriya Kishor Swasthya Karyakram (RKSK) in 2014 to improve health of adolescents. Adolescent Health Day (AHD) is an important intervention of RKSK for outreach and to secure convergence among relevant departments. OBJECTIVES: The objective of this study is to design and document methodology for effective implementation of AHD. MATERIALS AND METHODS: This study was conducted in Talod block of Sabarkantha district of Gujarat. The methodology was developed using ABCDE approach - assess, build, create, deliver, and evaluate. RESULTS: During assess phase, experts identified convergence an important component for successful implementation of RKSK. Formative research reaffirm that convergence played an important role in effective implementation of RKSK. Findings from these two phases led to the creation of a methodology which was used to deliver AHDs. This was further evaluated using interviews with key stakeholders in health and education department. It is now being used to organize AHDs in the district. CONCLUSION: ABCDE approach can be used to develop a better health interventions for National Health Programs.

Investigation of dissolved cellulose in development of buccal discs for oromucosal drug delivery.

Mucoadhesive formulations have a wide scope of application for both systemic and local treatment of various diseases. In the case of recurrent aphthous stomatitis, to ensure effective therapy, the concentration of corticosteroids, and/or anesthetics at the mouth ulcer side should be maintained with minimal systemic absorption. Therefore, the aim of the study was to investigate cellulose-based formulations, in achieving suitable hardness, mucoadhesiveness, and sustained release of the active ingredients directed towards the mucosa for an extended period of time (∼4 h). This was examined by creating polymer reinforced cellulose composites which consisted of porous cellulose discs (CD) and different polymer components namely polyethylene glycol 6000 (PEG6000), polyethylene glycol 400 (PEG400), and ethyl cellulose. Empty CDs were formed by dropping dissolved cellulose into coagulation medium. The empty porous CDs were immersed into different drug loading solutions which were prepared by dissolving three different concentrations of triamcinolone acetonide and lidocaine hydrochloride in five different ratios of PEG 6000:PEG 400:ethanol (w:w:w %) solutions. All formulations were investigated regarding drug content, release, hardness, and mucoadhesive properties. The results indicate that the non-dispersing buccal discs had sufficient hardness, drug content and in vitro release properties, but further studies are needed to achieve proper mucoadhesiveness.

Knowledge of hepatitis B among healthy population: A community-based survey from two districts of Gujarat, India.

BACKGROUND: Hepatitis B is the world's most common blood-borne viral infection, accounting for 2 billion infections, 350 million carriers, and 6 lakh deaths annually. Country like India still harbors approximately 30-60 million hepatitis B virus (HBV) carriers. A modest estimate would put the number of deaths occurring due to HBV infection per year in India to around 100,000. To prevent transmission and progression of the disease, proper community awareness including prevention is necessary. Therefore, this study aims to study the knowledge awareness among the healthy population about hepatitis B including knowledge regarding vaccine. METHODOLOGY: A community-based cross-sectional study was undertaken in two districts of Gujarat. Cluster sampling (30 clusters) was used, and pretested questionnaire was administered to 600 (with a prevalence rate of 5% in Gujarat having design effect of 2 within 95% confidence interval and 10% nonrespondent) healthy individuals, who heard about hepatitis B. Data handled and analyzed in EpiData Analysis V2.2.2.183. RESULTS: Majority of the participants knew about symptoms whereas only 41% knew about prevention methods and few 34% knew about the mode of transmission. Although 40% sample has knowledge about the availability of vaccination, only 20% were self-vaccinated. The common reason for nonvaccination was lack of awareness. CONCLUSIONS: Only one-third of the populations in study districts are aware about hepatitis B and its vaccine. Less than one-fifth of the populations are vaccinated for hepatitis B. Important knowledge deficits about the routes of hepatitis B transmission/prevention were identified. Continued efforts should be made to develop and implement hepatitis B educational campaigns/health promotion for these communities.
