ABSTRACT
Objective: Stroke is one of the leading causes of death and disabilities worldwide. Cost-effectiveness analysis helps identify neglected opportunities
by highlighting interventions that are relatively inexpensive, yet have the potential to reduce the disease burden substantially. In India, there are
wide social and economic disparities. Socioeconomic environment influences occupation, lifestyle, and nutrition of social classes which in turn would
influence the prevalence and profile of stroke. By reduction of delays in access to hospital and improving provision of affordable treatments can
reduce morbidity and mortality in patients with stroke in India. This study is designed to measure and compare the costs (resources consumed) and
consequences (clinical, economic, and humanistic) of pharmaceutical products and services and their impact on individuals, healthcare systems and
society.
Methods: The purpose of this study is to analyze and conduct a cost-effectiveness analysis for the treatment of stroke in Guntur City Hospitals.
The patients were treated either with aspirin or clopidogrel. The health outcomes were measured using Modified Rankin Scale, A prominent risk
assessment scale for stroke. The pharmacoeconomic data were computed from the patient data collection forms.
Result: The incremental cost-effectiveness ratio of aspirin and clopidogrel were calculated to be Rs. 8046.2/year.
Conclusion: The study concludes that aspirin has the increased socioeconomic impact when compared to Clopidogrel and we can see that the earlier
therapy has supported discharge, home-based rehabilitation along with reduced hospital stay and hence preferable.
Keywords: Stroke, Pharmacoeconomics, Cost-effectiveness analysis, Aspirin, Clopidogrel, Incremental cost-effectiveness ratio.
There is often more than one way of doing something in healthcare.
For
example, there may be two different drugs that can be used to treat
depres sion, or two surgical techniques for the management of dysmenorrhoea.
Note that interventions may be compared against each other ( for example
antibiotic A against antibiotic B) or against a ' do nothing' scenario.
There are different ways in which we can choose one of these options.
We may
decide to pick the more effective surgical technique, or we may decide to
select the less costly antidepressant. Economic evalu ation is a generic term for
techniques that are used to identify, measure and value both the costs and the
outcomes of healthcare interventions. An economic evaluation is concerned
with identifying the differences in costs and outcomes between options. It can
be defined as a study that compares the costs and benefits of two or more
alternative interventions; so, the main components are costs and benefits
CUA is a formal economic technique for assessing the efficien
cy of healthcare interventions. It is
considered by some to be a specific type of cost effectiveness analysis in which the measure of
effectiveness is a utility or preference adjusted outcome.
In a cost
benefit analysis (CBA) the outcomes of the two alternatives
are measured using monetary values, that is, the monetary value
attached to the health states produced by the two interventions.
Eligibility for national screening programmes can be personalised according to individual risk in order to improve outcomes and reduce costs. Existing methods of economic evaluation can be adapted to identify risk thresholds and help optimise services. We describe the development of a decision model used to evaluate the cost-effectiveness of risk-based screening for diabetic retinopathy.

Strategy to incorporate pharmacoeconomics into pharmacotherapy Ravi Kumar Yadav
Pharmacoeconomics of the health care intervention is equally important like the safety and efficacy of drug. The various strategies are available to incorporate pharmacoeconomics into pharmacotherapy. The most popular strategies for applying pharmacoeconomics to assess the value of pharmaceutical products and services include using the results of published pharmacoeconomic studies, building economic models, and conducting pharmacoeconomic research.
Pharmacoeconomics is a branch of health economics which compares the value of one drug or a drug therapy to another.
By understanding the principles, methods, and application of pharmacoeconomics, healthcare professionals will be prepared to make better decisions regarding the use of pharmaceutical products and services.
Abstract: Now a days detection of patients with elevated risk of diabetes mellitus is developing critical to the improved prevention and overall health management of these patients. We aim to apply association rule mining to electronic medical records (EMR) to invent sets of risk factors and their corresponding subpopulations that represent patients which have high risk of developing diabetes. With the high linearity of EMRs, association rule mining generates a very large set of rules which we need to summarize for easy medical use. We reviewed four association rule set summarization techniques and conducted a comparative evaluation to provide guidance regarding their applicability, advantages and drawbacks. We proposed extensions to incorporate risk of diabetes into the process of finding an optimum summary. We evaluated these modified techniques on a real-world border line diabetes patient associate. We found that all four methods gives summaries that described subpopulations at high risk of diabetes with every method having its clear strength. In this extension to the Bottom-Up Summarization (BUS) algorithm produced the most suitable summary. The subpopulations identified by this summary covered most high-risk patients, had low overlap and were at very high risk of diabetes.

ABSTRACT
The basic idea of a QALY is straightforward. The amount of time spent in a health state is weighted by the utility score given to
that health state. It takes one year of perfect health (utility score of 1) to generate one QALY, whereas one year in a health state
valued at 0.5 is regarded as being equivalent to half a QALY. Thus, an intervention that generates four additional years in a health
state valued at 0.75 will generate one more QALY than an intervention that generates four additional years in a health state valued
at 0.5. This paper discusses effect of self-medication on health care taking an educational institution population comprising of
students, teaching and non-teaching staff in 2011.

A study on prescription pattern and rational use of statins in tertiary care ...SriramNagarajan16
Objectives
Our objectives are to evaluate prescription pattern and rational use of statins in a tertiary care corporate hospital.
Methodology
It was a prospective observational study conducted for a period of 6 months and included various departments of 300
bedded multi specialty tertiary care corporate hospital. A total of 200 patients were included and the study criteria
was inpatients and induvial more than 18 years of either gender who are prescribed with HMG-CoA reductase
inhibitors.
Results
In the present study 200 patients belonged to the age group of above 18 years, out of which about 65% were male
and 35% were female. Atorvastatin (67%) was prescribed mostly and Rosuvastatin (29.5%) was also used.
Conclusion
It is finally concluded that Rational and prophylactic use of statins can reduce further complications of Diabetes
Mellitus (DM) and cardiac events.
Statins treatment is favourable in long term treatment of diseases, it is most effectively used in treatment of serious
disease conditions which has shown its immense therapeutic role in treatment
Hypertension prediction using machine learning algorithm among Indonesian adultsIAESIJAI
Early risk prediction and appropriate treatment are believed to be able to
delay the occurrence of hypertension and attendant conditions. Many
hypertension prediction models have been developed across the world, but
they cannot be generalized directly to all populations, including for
Indonesian population. This study aimed to develop and validate a
hypertension risk-prediction model using machine learning (ML). The
modifiable risk factors are used as the predictor, while the target variable on
the algorithm is hypertension status. This study compared several machine-learning algorithms such as decision tree, random forest, gradient boosting,
and logistic regression to develop a hypertension prediction model. Several
parameters, including the area under the receiver operator characteristic area
under the curve (AUC), classification accuracy (CA), F1 score, precision,
and recall were used to evaluate the models. Most of the predictors used in
this study were significantly correlated with hypertension. Logistic
regression algorithm showed better parameter values, with AUC 0.829, CA
89.6%, recall 0.896, precision 0.878, and F1 score 0.877. ML offers the
ability to develop a quick prediction model for hypertension screening using
non-invasive factors. From this study, we estimate that 89.6% of people with
elevated blood pressure obtained on home blood pressure measurement will
show clinical hypertension.
Fuzzy Bi-Objective Preventive Health Care Network DesignGurdal Ertek
Preventive healthcare is unlike healthcare for a cute ailments, as people are less alert to their unknown medical problems.In order to motivate public and to attain desired participation levels for preventive programs,the attractiveness of the healthcare facility is a major concern.Health economics literature indicates that attractiveness to a facility is significantly influenced by proximity of the clients to it.Hence attractiveness is generally modeled as a function of distance.However, abundant empirical evidence suggests that other qualitative factors such as perceived quality, attractions nearby, amenities, etc. also influence attractiveness. Therefore, are alistic measures hould in corporate the vagueness in the concept of attractiveness to the model.The public policymakers should also maintain the equity among various neighborhoods, which should be considered as a second objective.Finally, even though general tendency in the literature is to focus on health benefits,the cost effectiveness is still a factor that should be considered.In this paper,a fuzzy bi-objective model with budget constraints of the problem is developed.Later,by modelling the attractiveness by means of fuzzy triangular numbers and treating the budget constraint as a soft constraint, a modified (and more realistic)version of the model is introduced. Two solution methodologies, namely fuzzy goal programming and fuzzy chance constrained optimization are proposed as solutions.Both the original and the modified models are solved within the framework of a case study in Istanbul,Turkey.In the case study,the Microsoft Bing Map is utilized in order to determine more accurate distance measures among the nodes.

Healthy Savings. Medical Technology and the Economic Burden of DiseaseRevital (Tali) Hirsch
As America ages and sedentary lifestyles and unhealthy diets become more common, experts agree the nation is suffering a sharp rise in the prevalence of chronic disease. As the 21st century unfolds, technology – in the form of advanced diagnostic and therapeutic devices -- can meet the need for early detection and more effective management of illness. Some researchers, however, have questioned whether the overall benefit of technical advances outweighs the costs -- a question this report definitively answers.
Accordingly, researchers at the Milken Institute undertook a comprehensive, quantitative documentation of medical technology's impact on the economic burden of disease. The study also projects how future innovation in this sector would affect the health care system and the larger economy -- a positive benefit of more than $23 billion a year for the United States.
The study takes a systematic approach to documenting the full costs and broader economic benefits of health care investments by examining innovations pertaining to four prevalent causes of disability and death: heart disease, diabetes, colorectal cancer, and musculoskeletal disease. The report considers therapeutics and diagnostic devices that are widely used and have substantially affected the lives of patients as well as the overall U.S. economy. Among the 10 devices or device-based procedures studied are pacemakers, insulin infusion pumps, colonoscopies, and joint replacement surgery.
The data demonstrate that the use of medical technology brings considerable economic benefits. These are seen in both aggregate savings in treatment expenditures and prevention as well as the reduction of "indirect impact" through larger contributions to the economy.

Higuchi’s kinetics, and the mechanism of drug release was found to be Non-Fickian Diffusion anomalous Super Case-II Transport (n= 0.963).
In recent years many advancement has been made in research and development of Oral Drug Delivery System. Concept of Novel Drug Delivery System arose to overcome the certain aspect related to physicochemical properties of drug molecule and the related formulations.
Purpose of this review is to compile the recent literature with special focus on Gastro Retentive Drug Delivery Systems to give an update
on pharmaceutical approaches used in enhancing the Gastric Residence Time (GRT). Various approaches are currently used including Gastro Retentive Floating Drug Delivery Systems(GRFDDS),swelling and expanding system, polymeric bioadhesive systems, modifiedshape
systems, high density system and other delayed gastric emptying devices. These systems are very helpful to different problem solve during the formulation of different dosage form. The present work also focuses on the polymers used in floating drug delivery systems
mostly from natural origin. Floating drug delivery systems are less dense than gastric fluids; hence remain buoyant in the upper GIT for a
prolonged period, releasing the drug at the desired/ predeterminedrate. This review article focuses on the recent technological development in floating drug delivery systems with special emphasis on the principal mechanism of floatation and advantages of achieving gastric
retention, brief collection on various polymers employed for floating drug delivery systems etc. In addition this review also summarizes the In –Vitro and In -Vivo studies to evaluate their performance and also their future potential.
The main objective of the present research work is to formulate the Clopidogrel Fast Dissolving tablets. Clopidogrel, an antiplatelet drug, belongs to BCS Class-II and used to control Heart attack, Hypertension by inhibiting Platelet activation and aggregation .The Fast Dissolving tablets of Clopidogrel were prepared employing different concentrations of Crospovidone and Croscarmellose sodium in different combinations as a Superdisintegrant by Direct Compression technique using 32 factorial design.

According to SUPAC guidelines, the formulation (F5) containing combination of 15% Crospovidone and 15% Croscarmellose, is the most similar formulation (similarity factor f2=91.3936, dissimilarity factor f1= 1.203& No significant difference, t= -0.00062) to marketed product (PLAVIX-75). The selected formulation (F1) follows First order, Higuchi’s kinetics, mechanism of drug release found to be Fickian Diffusion (n= 0.226).
ABSTRACT: IASP (International Association for study of pain) defined pain as “an unpleasant, sensory and
emotional experience associated with actual or potential tissue damage or described in terms of such damage”.
Chronic Pain can be more described as a disease rather than a symptom. Antidepressants are the drugs that can elevate
the mood. Recent trials have elucidated that anti- depressants can be of worth in treating chronic pain conditions.
However, the safe use of these drugs depends on upon the clinician or any other health professional and their ability to
choose the right tolerated drug at safe doses. Any psychiatric comorbidity must be treated to avail best results with
anti-depressant therapy.However, most of the trials focus upon only Tri-CyclicAntidepressants and Selective
Serotonin Reuptake Inhibitors. Research into other novel Anti-depressant drugs may lead to best chances of recovery
in patients with chronic pain.

ABSTRACT
Background:The main objective of the study is to determine the anti-arthritic effect of whole plant ethanolic extract of Polygonum glabrum
belonging to the family Polygonaceae in Female wistar rats using the Freund’s Complete Adjuvant (FCA) model . Methods:The plants areal
parts were collected near Tirupathi hills, Chittoor district of Andhra Pradesh in India. The Phytoconstituents were identified through the
chemical tests. Ethanol (95%) was used to obtain the whole plant extraction through Soxhlet extractor. Female SD rats were used for antiarthritic
screening. Arthritis was induced using FCA, and the anti-arthritic effect of the ethanolic extract of P.glabrum was studied at doses
of 250 and500 mg/kg. The effects were compared with those of indomethacin (10 mg/kg). At the end of the study, theliver enzyme levels were
determined and a radiological examination was carried out. Results and Discussion:The preliminary phytochemical analysis of the ethanolic
extract of Polygonum glabrum showed the presence of alkaloids, tannins, flavonoids and saponins. P. glabrum at 250 and 500 mg/kg
significantly inhibited the FCA-induced arthritis in the rats. This was manifested by as a decrease in the paw volume. The arthritic control
animals exhibited a significant decrease in body weight compared with control animals without arthritis. P. glabrum treated animals showed
dose dependent reduction in decrease in body weight and arthritis.At the same time, P.glabrum significantly altered the biochemical and
haematological changes induced by FCA (P < 0.05). The anti-arthritic effect of P.glabrum was comparable with that of Indomethacin.
Conclusion:The whole plant extract of P.glabrum showed significant anti-arthritic activity against FCA-induced arthritis in female Wistar
rats.

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

income patients, due to their lower earning. By reduction of delays in
access to hospital and improving provision of affordable treatments can
reduce morbidity and mortality in patients with stroke in India. The era,
in which high-tech care is generally favored, there is little likelihood that
a less complex and cost-effective therapy will emerge as the preferred
choice unless there are data to suggest the same. However, comparative
cost-effectiveness analysis can lead to such insights. Hence, there is a
need to carry out comparative cost-effective studies among patients
receiving these therapies [20].
The aims and objectives of the study include:
• To evaluate the cost of management of stroke, its predictors, and the
impact on social determinants of the family
• Toanalyzeandconductacost-effectivenessanalysisforthetreatment
of stroke in Guntur City Hospitals
• To evaluate the burden of cost in patients with stroke
• Toauditallthepharmacotherapy,qualityoflifeandcost-effectiveness
by comparing different drug combinations.
METHODS
The study was a single-center, non-interventional observational
study conducted over a period of 6 months, i.e. from August 2016 to
January 2017 in the Department of Neurology, Guntur City Hospital,
Kothapet, Guntur, and Andhra Pradesh. The data required for the
study was collected from the patients at Guntur City Hospital,
Guntur. A total of 100 patients from the Neurology Department were
taken in the study. An equal number of patients, i.e., 50 each (n=100)
have been prescribed with aspirin and clopidogrel, respectively. The
health outcomes were measured using Modified Rankin Scale, A
prominent risk assessment scale for stroke. The pharmacoeconomic
data were computed from the patient data collection forms. The
data were statistically analyzed using SPSS (Statistical Package
for Social Sciences) with version 24.0 (SPSS Inc., Bengaluru). All
the continuous variables of normal distribution were presented in
the form of mean with standard deviation. Statistically, the cost-
effectiveness was determined using the formula of incremental
cost-effectiveness ratio (ICER) which is recommended by the World
Health Organization.
The ICER can be estimated by:

Inclusion criteria
• All adult inpatients of age >55 years admitted to neurology
department
• Patientshavingpastandpresentmedicalconditionofischemicstroke
• Patients with history of ischemic stroke and post-stroke disabilities
• Smokers and alcoholics
• Drug-induced stroke conditions (e. g. Use of oral contraceptives).
Exclusion criteria

• Patients with hemorrhagic stroke
• Patients age below 55 years.
RESULTS AND DISCUSSION
Health economics enacted the foundation for the branch of
pharmacoeconomics for collating different health-care interventions,
especially pharmaceuticals and generating meaningful cost-effective
solutions for disease management. Policymakers increasingly use cost-
effectiveness analyses to inform decision-making on competing health-
care interventions.
stroke is an important setting, which was a panic for economic
evaluations because of the wide range of issues involved for the
individual and society. It is one of the most expensive diseases as far
as treatment is perturbed, as it generates higher health-care expenses
than those produced by other disease. The present study enumerates
to the current movement toward the extensive considerations in cost-
effectiveness analyses. The choice of aspirin over clopidogrel-yielded
increased health benefits at a minimized cost. The efficacy significantly
affects the total costs of the disease. We studied the cost (direct medical,
nonmedical, and indirect) and socioeconomic impact of stroke in
Guntur, India.
Domains related to physical, mental, emotional, and social functioning
are included under a multidimensional concept called health-related
quality of life. It goes beyond direct measures of population health,
life expectancy, and causes of death, and focuses on the impact health
status has on quality of life. Valuing health-related quality of life is not
straightforward, and the use of QALYs requires caution. In the present
article, we decided to base all QALY values on Modified Rankin Scale.
Modified Rankin Scale is the most used tool for which we could find
published values on all events and health states for input into our
model.
In our study, the age group analysis shows that out of 100 patients, the
age between 55 and 65 years of age having more number of patients,
i.e., 74 (74%) stroke patients and 20 (20%) patients were from the age
group of 66 to 75 years, and finally, 6 (6%) patients were from the age
group of 76 to 85 years of age. Age group of 55-65-year-old patients was
mostly affected by stroke (Fig. 1).
Gender-wise distribution shows that out of 100 stroke patients’ males
were found to be 67 (67%) and females were 33 (33%) (Fig. 2). This
shows that the males are highly affected by stroke.

Gopi et al.
When evaluated for the risk factors of stroke majorly for the smoking
status the analysis showed that out of 100 patients, 62 (62%) were
smokers and 38 (38%) were non-smokers (Fig. 3). This reveals that
Smokers are at a higher risk for the occurrence of stroke.
When evaluated for the alcohol consumption status, the analysis
showed that out of 100 patients, 89 (89%) were alcoholics, whereas
11 (11%) were non-alcoholics (Fig. 4). This proves the fact that alcohol
consumption causes higher blood pressure, thereby increasing the risk
of stroke.
Comorbidities such as hypertension and diabetes mellitus have been
shown to increase the risk of stroke. In our study, out of 100 patients,
39 (39%) patients have hypertension, 5 (5%) patients have diabetes
mellitus, 32 (32%) patients have both hypertension and diabetes
mellitus, and 24 (24%) patients have no recorded comorbidities
(Fig. 5). Most of the patients either have hypertension or a treacherous
combination of hypertension and diabetes mellitus.
The evaluation of quality of life of all the stroke patients receiving
either the aspirin or the clopidogrel therapy shows that the sum of
Modified Rankin Scale scores in aspirin is 95 and the sum of Modified
Rankin Scale scores in clopidogrel is 115 (Fig. 6). The low Modified
Rankin Scale score in aspirin denotes the increased quality of life
in the patients receiving Aspirin. The high-Modified Rankin Scale
in clopidogrel indicates the decreased quality of Life in the patients
receiving clopidogrel. Compared to clopidogrel, aspirin shows good
health-related outcomes.
Based on Table 1, the students paired t-test was used to compare the
cost difference between aspirin and clopidogrel. From the students
paired t-test, we concluded that aspirin is more cost-effective than
clopidogrel.
ICER=Rs. 8046.2
The ICER can be calculated by dividing the difference in costs of
control group and intervention groups with the difference in the
effects caused by the control group and the interventional group. The
total costs of the control group, i.e., patients’ prescribed with aspirin
are evaluated to be Rs. 388219. The total costs of the interventional
group i.e., patients prescribed with Clopidogrel are evaluated to be Rs.
549143. The sum of Modified Rankin Scale scores of the control group
is found to be 95 whereas the sum of Modified Rankin Scale scores of
the interventional group is found to be 115. The ICER was calculated to
be Rs. 8046.2 (Table 2). Low ICER than the threshold determines the
cost-effectiveness of the drug therapy.
This analysis shows that Aspirin is more cost-effective than Clopidogrel
in the treatment of stroke also offering a favorable adverse effect profile
and quality of life in comparison to the latter. Stroke, given its chronicity
and associated morbidity and mortality, constitutes a significant disease
burden to the society, both in terms of the health-related repercussions
as well as financial costs incurred due to morbidity and cumulative cost
of drug therapy. Hence, it is important to administer drugs that are cost-
effective and have minimal side effects. This is particularly important
in a developing country like India, where the accretive cost of the long-
term therapy is often a significant deterrent to patient compliance.
The results of this study contribute toward decision-making involved
in formulary management and by clinicians treating the patients with
stroke.
CONCLUSION
The study concludes that the pharmacoeconomic evaluation of stoke
is essential to obtain optimal therapy at lowest price and which
medication helps the poor and middle-class patients to give appropriate
health-care service. The cost driving factors in case of aspirin were
found to be manageable income, better outcomes, and reduced length

of hospital stay. In contrast, the clopidogrel cost-driving factors were
higher income, poor outcomes, and increased length of hospital stay.
Aspirin has the increased socioeconomic impact when compared to
clopidogrel, and we can see that the earlier therapy has supported
discharge, home-based rehabilitation along with reduced hospital stay.
