DESIGN AND DEVELOPMENT OF RILPIVIRINE NANOPARTICLE CONTAINING CHITOSAN USING IONIC GELATION METHOD FOR HIV INFECTIONS
Objective: The primary objective of the current research was to prepare rilpivirine loaded Nanoparticles containing Chitosan using the ionic gelation method for HIV infections.
Methods: The nanoparticles of rilpivirine were prepared using the ionic gelation technique. Further, nanoparticles were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and in vitro drug release.
Results: The optimized nanoparticles were found with a particle size of 130.30±5.29 nm (mean±SD) and entrapment efficiency (% EE) of 77.10±0.50%. Scanning electron microscopy technique exposed spherical particles with uniform size. It was observed that the nanoparticles created showed the absence of the crystalline nature of the drug and its switch to the amorphous state. Results showed that more than 45% of the pure drug is released in 50 min and after 90 min almost about 95% of the drug is released.
Conclusion: The research study concluded that the in vitro release profile of nanoparticles was found to be sustained up to 24 hr. Sustained release of the rilpivirine could improve patient obedience to drug regimens, growing action effectiveness. 
Adverse drug reactions in a tertiary care teaching hospital in India: analysis of spontaneously reported cases
Background: Epidemiological data are limited regarding clinical characteristic of adverse drug reactions (ADRs) in India.Aim: The aim was to assess ADRs with reference to the causative drugs, seriousness and their other clinical characteristics in Indian tertiary care teaching hospital.Methods: A spontaneous reporting based ADR monitoring study was conducted over a period of 2 years. The World Health Organization (WHO) definition of an ADR and its seriousness was adopted. The organ system involvement was labeled by WHO-ADR terminology. ADRs were analyzed for causality by Naranjo’s algorithm, preventability by modified Schumock and Thornton’s criteria and types of reactions by Rawlins and Thompson classification. Subgroup analysis was performed between serious and non-serious reactions.Results: Of the total of 135 reactions reported 111 reactions from 97 patients were included for analysis. The incidences of overall and serious ADRs were 0.25 and 0.06 per 1000 patients, respectively. The most commonly implicated organ systems were skin and appendages (52.25%). The major causative drug classes were antimicrobials (40.28%), central nervous system (23.61%) and autacoids (15.97%). About two-thirds of the reactions (65.77%) were classified as probable and one-tenth (8.10%) as preventable. The factors significantly associated with serious reactions were age group 40-60 years (odds ratio [OR]: 5.51), parenteral drugs (OR: 2.96), central and peripheral nervous system disorders (OR: 5.06), body as a whole - general disorders (OR: 9.05) and acute onset reactions (OR: 52.62).Conclusion: Antimicrobials are common causative agents. Cohort study is recommended to confirm the risk factors of serious ADRs in Indian population
PREPARATION, CHARACTERIZATION, AND OPTIMIZATION OF MICROEMULSION FOR TOPICAL DELIVERY OF ITRACONAZOLE
Microemulsions (ME) have been proved to increase the cutaneous absorption of both lipophilic and hydrophilic medicaments when compared to conventional vehicles (emulsions, pure oils, aqueous solutions). Hence the aim of present investigation is to prepare, characterize and optimize microemulsion of Itraconazole (ITZ). Itraconazole is an anti fungal agent, most widely used in the ringworm infection. It is classified as class III drug as per BCS classification. It indicates lower permeability through skin. Therefore objective of the research is to improve permeability of Itraconazole through skin. Microemulsion was prepared using eucalyptus oil, tween 20 and methanol as oil phase, surfactant and co-surfactant respectively. Pseudo ternary phase diagrams were constructed to find out optimum ratio of oil: Smix (surfactant: Co-Surfactant): water. A 32 full factorial design was applied for the optimization of prepared microemulsion. Microemulsion was evaluated for globule size, zeta potential, in-vitro diffusion study etc. Results of globule size measurements and zeta potential indicated ME7 had high stability then other formulation of microemulsion. For the optimization transdermal flux and %Q6 was selected as dependant variables. Results of optimization study also revealed ME 7 as optimized microemulsion for high permeability to the skin. Further ME7 was compared to marketed Itraconazole preparation (ITASPORE) and evaluated using similarity factor F2. Results of F2 value was not near to 100 indicated there is no similarity in diffusion profiles of ME7 and ITASPORE. Hence, indirectly it suggest there was increased in permeability of drug by preparing microemulsion

Objective: In the present investigation self microemulsifying drugdelivery system (SMEDDS) of Fexofenadine hydrochloride was developed forimproving solubility and dissolution rate of drug. Material Method: Solubility of Fexofenadine hydrochloride wasdetermined in various non-aqueous vehicles such as oils, surfactants, andco-surfactants. Psuedoternary phase diagrams were constructed to identify theself-micro emulsification region. Four formulations of SMEDDS were selected fromthe optimum concentration of oils, surfactant, and co-surfactants from psuedoternary diagrams. Resultsand Discussion: Selected formulations were evaluated for droplet size,in-vitro drug dissolution, drug content and solubility of drug. The optimumformulation was 20% oleic acid, 26.3% ACONON MC8 and 53.3% PEG 400. Self-microemulsification with the combination of oleic acid and ACONON MC8 was foundhigher. Conclusion: The resultsobtained from in vitro dissolutionindicated Fexofenadine hydrochloride in SMEDDS dissolved rapidly and completelyin phosphate buffer pH 6.8 which was used as dissolution medium
Advancement in Reperfusion Injury Awareness and Mitigation
Understanding reperfusion damage, raising knowledge of its underlying processes, and creating measures to lessen its negative consequences have all seen significant progress over time. The developing knowledge of the pathophysiological processes, such as oxidative stress, inflammation, calcium excess, and mitochondrial dysfunction, that lead to reperfusion damage. Clinicians may now identify biomarkers and use modern imaging techniques to identify reperfusion damage in its early phases, allowing for prompt treatment and better patient outcomes. Real-time evaluation of tissue viability during reperfusion is now possible thanks to the development of non-invasive monitoring techniques, which supports clinical judgment. The use of pharmaceutical substances that target certain pathways, such as antioxidants, anti-inflammatory substances, and calcium homeostasis regulators. Additionally, cutting-edge approaches like therapeutic hypothermia and remote ischemia conditioning have demonstrated promise in lowering reperfusion damage and enhancing patient prognosis. Our knowledge of the underlying processes has considerably increased thanks to improvements in reperfusion injury recognition and mitigation, which have also created new opportunities for therapeutic intervention. These developments are anticipated to result in more efficient methods for reducing reperfusion damage and eventually enhance patient outcomes in a variety of therapeutic situations via continuing study and cooperation
Analytical evaluation of drug package inserts in India
Background: A drug package insert or prescribing information is a document provided along with a prescription medication to provide additional information about that drug. Drug package inserts are approved by the administrative licensing authority. A package insert is intended to provide information for the safe and effective use of the respective drug. Product information provided by pharmaceutical companies has been determined to be far from adequate and not conforming with requirement of Indian regulatory. Hence, it was decided to conduct a study to assess the presentation and completeness of clinically important information provided in the currently available package inserts in India.Methods: Package inserts were provided by five pharmacies on request. The package inserts were collected in 10 weeks’ period and then they were analyzed for presentation and completeness of clinical information according to heading mentioned in Section 6.2 and 6.3 of schedule D of Drug and Cosmetic Rule, 1945. If the information was present under relevant heading, it was scored as one. Otherwise as score of zero was assigned. Total score for each heading was calculated by adding the score from the individual package inserts.Results: 70 package inserts were included in the study. None of the reviewed package inserts contained all the sections as required by the Drugs and Cosmetics Act. Total 15 headings were evaluated under both Section 6.2 and 6.3, highest value for the presence of heading were 12 out of 15 heading evaluated. That shows the best value of compliance was 80%.Conclusion: Accurate drug product information is important for the safe and effective use of medicines. Hence, pharmaceutical companies and regulators should ensure that accurate and up to date product information is provided in the package inserts
Future and potential spending on health 2015-40 : development assistance for health, and government, prepaid private, and out-of-pocket health spending in 184 countries
Background The amount of resources, particularly prepaid resources, available for health can affect access to health care and health outcomes. Although health spending tends to increase with economic development, tremendous variation exists among health financing systems. Estimates of future spending can be beneficial for policy makers and planners, and can identify financing gaps. In this study, we estimate future gross domestic product (GDP), all-sector government spending, and health spending disaggregated by source, and we compare expected future spending to potential future spending. Methods We extracted GDP, government spending in 184 countries from 1980-2015, and health spend data from 1995-2014. We used a series of ensemble models to estimate future GDP, all-sector government spending, development assistance for health, and government, out-of-pocket, and prepaid private health spending through 2040. We used frontier analyses to identify patterns exhibited by the countries that dedicate the most funding to health, and used these frontiers to estimate potential health spending for each low-income or middle-income country. All estimates are inflation and purchasing power adjusted. Findings We estimated that global spending on health will increase from US24.24 trillion (uncertainty interval [UI] 20.47-29.72) in 2040. We expect per capita health spending to increase fastest in upper-middle-income countries, at 5.3% (UI 4.1-6.8) per year. This growth is driven by continued growth in GDP, government spending, and government health spending. Lower-middle income countries are expected to grow at 4.2% (3.8-4.9). High-income countries are expected to grow at 2.1% (UI 1.8-2.4) and low-income countries are expected to grow at 1.8% (1.0-2.8). Despite this growth, health spending per capita in low-income countries is expected to remain low, at 195 (157-258) per capita in 2040. Increases in national health spending to reach the level of the countries who spend the most on health, relative to their level of economic development, would mean $321 (157-258) per capita was available for health in 2040 in low-income countries. Interpretation Health spending is associated with economic development but past trends and relationships suggest that spending will remain variable, and low in some low-resource settings. Policy change could lead to increased health spending, although for the poorest countries external support might remain essential.Peer reviewe

Trends in future health financing and coverage: future health spending and universal health coverage in 188 countries, 2016–40
Background: Achieving universal health coverage (UHC) requires health financing systems that provide prepaid pooled resources for key health services without placing undue financial stress on households. Understanding current and future trajectories of health financing is vital for progress towards UHC. We used historical health financing data for 188 countries from 1995 to 2015 to estimate future scenarios of health spending and pooled health spending through to 2040. Methods: We extracted historical data on gross domestic product (GDP) and health spending for 188 countries from 1995 to 2015, and projected annual GDP, development assistance for health, and government, out-of-pocket, and prepaid private health spending from 2015 through to 2040 as a reference scenario. These estimates were generated using an ensemble of models that varied key demographic and socioeconomic determinants. We generated better and worse alternative future scenarios based on the global distribution of historic health spending growth rates. Last, we used stochastic frontier analysis to investigate the association between pooled health resources and UHC index, a measure of a country's UHC service coverage. Finally, we estimated future UHC performance and the number of people covered under the three future scenarios. Findings: In the reference scenario, global health spending was projected to increase from US20 trillion (18 trillion to 22 trillion) in 2040. Per capita health spending was projected to increase fastest in upper-middle-income countries, at 4·2% (3·4–5·1) per year, followed by lower-middle-income countries (4·0%, 3·6–4·5) and low-income countries (2·2%, 1·7–2·8). Despite global growth, per capita health spending was projected to range from only 413 (263–668) in 2040 in low-income countries, and from 1699 (711–3423) in lower-middle-income countries. Globally, the share of health spending covered by pooled resources would range widely, from 19·8% (10·3–38·6) in Nigeria to 97·9% (96·4–98·5) in Seychelles. Historical performance on the UHC index was significantly associated with pooled resources per capita. Across the alternative scenarios, we estimate UHC reaching between 5·1 billion (4·9 billion to 5·3 billion) and 5·6 billion (5·3 billion to 5·8 billion) lives in 2030. Interpretation: We chart future scenarios for health spending and its relationship with UHC. Ensuring that all countries have sustainable pooled health resources is crucial to the achievement of UHC.

Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study
Fitzmaurice C, Alsharif U, El Bcheraoui C, et al. Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2018;63(Suppl. 1):151-164.To estimate incidence, mortality, and disability-adjusted life years (DALYs) caused by cancer in the Eastern Mediterranean Region (EMR) between 2005 and 2015. Vital registration system and cancer registry data from the EMR region were analyzed for 29 cancer groups in 22 EMR countries using the Global Burden of Disease Study 2015 methodology. In 2015, cancer was responsible for 9.4% of all deaths and 5.1% of all DALYs. It accounted for 722,646 new cases, 379,093 deaths, and 11.7 million DALYs. Between 2005 and 2015, incident cases increased by 46%, deaths by 33%, and DALYs by 31%. The increase in cancer incidence was largely driven by population growth and population aging. Breast cancer, lung cancer, and leukemia were the most common cancers, while lung, breast, and stomach cancers caused most cancer deaths. Cancer is responsible for a substantial disease burden in the EMR, which is increasing. There is an urgent need to expand cancer prevention, screening, and awareness programs in EMR countries as well as to improve diagnosis, treatment, and palliative care services
