Authors: Kilci Fatih , Uyan Zeynep , Çelakıl Mehtap , Dogan Kenan , Bek Kenan
Published: March 2021

Abstract Aim: To evaluate the respiratory functions of children with
nephrotic syndrome (NS) by IOS and its correlation with spirometry.
Methods: Fifty-five NS patients aged 3–18 years were included as the
study group and 40 healthy children of the same age formed the control
group. Patients were divided into nephrotic phase (first attack and
relapse) and remission. Demographic, anthropometric and laboratory data
of the children were recorded. Respiratory functions were evaluated by
IOS and spirometry. Children over 6 years old performed both IOS and
spirometry while children under 6 years performed only IOS. Results: The
R (R5%, R10%, R5-20) and AX and Z5% values of IOS in patients with
nephrotic phase were higher than remission patients and control group
while spirometry indices of FEV1%, FEV1/FVC, PEF% and MEF25-75% were
lower. FEV1% showed negative correlation with R5%, R10%, R15%, X10%
and X15% results, FEV1/FVC% showed negative correlation with R5%,
R5-20 and X15% results, FVC showed negative correlation with X10%
results, MEF25-75% showed negative correlation with, R5%, R10%,
R5-20, X15%, F res, Z5% and AX results. Conclusion: Our study
demonstrated that respiratory functions measured by IOS and spirometry
were affected at the time of nephrotic phase in NS patients. And IOS, a
novel method easily applicable even in small children, is a valuable and
reliable tool to detect this condition; given its good correlation with
spirometry. Keywords Nephrotic syndrome, Respiratory functions,

Central vision loss, photopsia, floaters and macular edema in a highly
myopic patient can easily be misrelated to high myopia complications.
However, in atypical cases, detailed examination along with a thorough
diagnostic is required to establish the right diagnosis, which is often
beyond the limits of the condition originally considered.
Surgical repair of severely incompetent quadricuspid truncal valve
Authors: Boburg Rodrigo Sandoval , Mustafi Migdat , Hofbeck Michael , Schlensak Christian
Published: March 2021

The surgical management of truncus arteriosus poses a constant challenge
for the cardiac team treating the patient. A correct diagnosis, surgical
therapy and postoperative management are crucial for the survival of the
patient. Almost 30% of the patients show an abnormal number of leaflets
in the truncal valve, the majority being quadricuspid valves.
Additionally, around 25% of the patients show some degree of truncal
valve incompetence. We demonstrate an effective way to reconstruct
incompetent, quadricuspid valves with good postoperative outcome.

Authors: Hess Nicholas , Sultan Ibrahim , Wang Yisi , Thoma Floyd , Kilic Arman
Published: March 2021

Background: This study evaluated outcomes of cardiac operations with
very prolonged cardiopulmonary bypass (CPB) times. Methods: This was a
retrospective study of cardiac surgical procedures with very-long CBP
times (≥300 minutes) performed at a single institution. Primary outcomes
of operative (≤30-day) and one-year mortality were evaluated, and
secondary outcomes included use of mechanical support and postoperative
complications. A probability analysis was also conducted to identify the
correlation between operative mortality and CPB time. Results: 293
patients were included with a Society of Thoracic Surgeons predicted
risk of mortality of 2.51% (IQR 1.32%- 4.70%), and median CPB time of
340 minutes (IQR 315.0-385.0). Preoperative mechanical support included
intra-aortic balloon pump (IABP, n=4, 1.4%), Impella (n=0), or
extracorporeal membrane oxygenation (ECMO, n=2, 0.7%). Intraoperative
and operative mortality were 5.1% and 22.5%, respectively.
Intraoperative or postoperative mechanical support were utilized in 90
(30.7%) cases, including IABP (n=65, 22.2%), Impella (n=2, 0.68%), or
ECMO (n=23, 7.8%). Postoperative complications included prolonged
mechanical ventilation (n=121, 41.3%), renal failure (n=71, 24.2%),
stroke (n=20, 6.8%), and reoperation (n=95, 32.4%). One-year survival
for the overall cohort was 61.4%. Probability analysis identified a CPB
time of 446 minutes to be associated with 50% odds of operative
mortality. Conclusions: Cardiac operations requiring very-long CPB times
are associated with high rates of operative mortality and morbidity,
with a 50% operative mortality rate predicted for those with a CPB time
of 446 minutes or longer. Nonetheless, the majority of patients survive
at least 1 year, and these cases should not be considered futile.

Preservers of partial orders on the set of all variance-covariance matrices
Authors: Golubic Iva , Marovt Janko
Published: March 2021

Let H+n(R) be the cone of all positive semidefinite n x n real matrices.
Two of the best known partial orders that were mostly studied on subsets of
square complex matrices are the L?wner and the minus partial orders.
Motivated by applications in statistics we study these partial orders on H+n(R). We describe the form of all surjective maps on H+ n (R), n > 1, that
preserve the L?wner partial order in both directions. We present an
equivalent definition of the minus partial order on H+n(R) and also
characterize all surjective, additive maps on H+ n (R), n ? 3, that preserve
the minus partial order in both directions.

A few remarks on bounded homomorphisms acting on topological lattice groups and topological rings
Authors: Zabeti Omid
Published: March 2021

Suppose G is a locally solid lattice group. It is known that there are
non-equivalent classes of bounded homomorphisms on G which have topological
structures. In this paper, our attempt is to assign lattice structures on
them. More precisely, we use of a version of the remarkable
Riesz-Kantorovich formulae and Fatou property for bounded order bounded
homomorphisms to allocate the desired structures. Moreover, we show that
unbounded convergence on a locally solid lattice group is topological and we
investigate some applications of it. Also, some necessary and sufficient
conditions for completeness of different types of bounded group homomorphisms
between topological rings have been obtained, as well.

Improving the Statistical Power and Reliability of Research Using Amazon Mechanical Turk
Authors: Bentley Jeremiah W.
Published: March 2021

SYNOPSIS

Amazon Mechanical Turk (MTurk) is an increasingly popular source of experimental participants due to its convenience and low cost (relative to traditional laboratories). However, MTurk presents challenges related to statistical power and reliability. These challenges are not unique to MTurk, but are more prevalent than in research conducted with other participant pools. In this paper I discuss several reasons why research conducted with MTurk may face additional power and reliability challenges. I then present suggestions for dealing with these challenges, taking advantage of the comparative strengths of MTurk. The discussion should be of interest to Ph.D. students and other researchers considering using MTurk or other online platforms as a source of experimental participants as well as to reviewers and editors who are considering quality control standards for research conducted with this participant pool.

Published: March 2021

The Perak Malay Traditional houses are one of the relics that should be appreciated due to their space organization uniqueness which is not present in today's modern houses. The study of the house's space organization should highly be given attention for future generations to discern. The issue is there is minimal approach to appreciating the space organization and there is even no concern of its benefits if applied in the construction of modern houses today. Indeed, in an orientation before the construction of a residential house, the role of the environment including culture, way of life, especially the occupants of the residence are taken care of by a craftsman. Discussion between the host and the craftsman is an important aspect before the residence is established. Space requirements are the most in the architecture of a traditional Malay house, a space was born as a result of the activities of the society, by gender requirements in addition to the comfort of concern with the residential environment. Space requirements are common in almost every traditional Malay house in Malaysia but there are differences in orientation, climate, environment and local culture that trigger the use of space. The purpose of this study is to pass knowledge to the future generation in order to appreciate the relics house. For that, the objectives of this research are to analyse the spatial organization design and architecture of a traditional Malay house with Perak state based on space functional diversity through research on the role of space during the performance of activities. This paper employs qualitative research adapting the observation on-surrounding and the house's interior space. Besides, sketches on house spatial pattern, joinery detailing and joinery construction were some of the approaches that have been applied to obtain the data. To strengthen data acquisition, interviews with target groups like village heads or local house carpenters were made. The data were analyzed and the sketches were illustrated in diagrams to interpret the pattern of findings. The results strengthened the characteristics of the interior spatial organization for Perak house traditionally do influence the environment, society, cultural customs, beliefs and religions.

La memoria “viaggiante” fra identità e traduzione
Authors: Troisi S.Cristian
Published: March 2021

Una delle caratteristiche principali della memoria è il suo essere in movimento, il quale, attraversa in maniera trasversale: nazioni, epoche e tecnologie. Rappresenta, inoltre, uno degli aspetti più rilevanti nella costruzione dell’identità; definisce e scandice la vita di un individuo o un gruppo sociale, li caratterizza indelebilmente nel tempo, viene ri-mediata all’interno dei media e dei diversi gruppi della nostra società. Questo suo “viaggio” transnazionale che percorre lo spazio, il tempo e le tecnologie in una continua mediazione e ridefinizione lo si assimila al medesimo cammino che in una certa forma compie la traduzione. È innegabile come memoria, identità e traduzione siano intimamente connesse fra di loro e a ciò che è racchiuso nell’essenza umana, che deve intendersi in una dialettica dell’implicazione e dell’ipseità/alterità.
Simple Technique of Initial Speed Identification for Speed-Sensorless Predictive Controlled Induction Motor Drive
Authors: Stando Dariusz , Kazmierkowski Marian P.
Published: March 2021

This article presents a simple technique of identifying the initial speed that allows for restarting a sensorless induction motor (IM) drive controlled by a model predictive flux control (MPFC). Initial speed identification is required because, according to the research, the applied current-model reference adaptive system (C-MRAS) can restart the IM after failure only if the error of the initial speed set in the estimator is <25%. The proposed technique is based on short periods of flux generation for the certain initial speed and observation of the estimated torque respond. The direction of the estimated torque determines whether the real speed is higher or lower than the initial one set in the estimator. In two steps, the algorithm identifies the initial speed with an accuracy of 25%. This allows for a quick restart of the IM from any speed, eliminating the disadvantage of the sensorless drive control system with the C-MRAS speed estimator. The experimental results measured on a 50 kW drive which illustrates the operation and performances of the system are presented.

Authors: RAZUMOVSKII Denis Yu.
Published: March 2021

Subject. The article discusses the financial behavior of households, and financial decisions.
Objectives. I model patterns of households' financial behavior, referring the impact of stress factors on financial decisions.
Methods. The financial behavior was analyzed through approaches proposed by D. Kahneman, A. Tversky and R. Thaler. However, instead of experiments, I rely upon surveys evaluating the financial literacy and behavior of people in the Sverdlovsk Oblast via social networks and conduct my research as a member of the task force of the Regions Center for Financial Literacy at the Ural State University of Economics. I took part in the preparation of questionnaires.
Results. I proposed model patterns of financial behavior and substantiate what determines the behavioral pattern of people in distress. I also conclude that the impact of the COVID-19 on the financial and consumer behavior of people triggers destabilizing effects for the macroeconomic situation.
Conclusions. Financial behavior modeling will help forecast financial and consumer shocks when the macroeconomic situation is destabilized, thus transforming the social policy.

The Bystrinskii gabbro massif: the first data concerning composition, age and formation affiliation
Authors: Smirnov V. N. , Kazakov I. I. , Ponomarev V. S. , Ronkin Yu. L. , Storozhenko E. V.
Published: March 2021

Research subject. The research covered the geological position, material composition and rock age of a comparatively small (about 32 km2) Bystrinskii gabbro massif. This massif underlies a tectonic plate package consisting of serpentinized dunits and harzburgites of the ophiolite association in the Eastern boundary of the Middle Urals. Methods. The content of petrogenic elements was measured by the Х-ray fluorescence method using an Х-ray multichannel spectrometer CPM-35. The analysis of rare-earth element contents was conducted using a NexION 300S mass-spectrometer. The composition of rock-forming minerals was studied using an Х-ray microanalyzer CamecaSX100. The age of the massif was determined by the 147Sm-143Nd method of isotope dating. Amphibole geobaometers were used to determine the depth of the rock formation. Results. According to the petro- and geochemical features and composition of the rock-forming minerals, the 147Sm-143Nd isotope age of the rocks was found to be 587 Ma. It was shown that gabbroids in the massif are represented by two petrographic varieties. The predominant type of the rocks is gabbrodolerites, which are similar to the isotropic gabbros of undisturbed ophiolite sections in terms of mineral composition, structure, geochemical features and the depth of formation (not more than 2–3 km). The mapping results showed the massif under study to be the largest among those described thus far. The medium grained gabbroids, which are present in lesser quantities, differ sharply from gabbrodolerites in terms of lower contents of Fe, Ti, both rockforming (K, Na) and rare (Li, Rb, Cs) alkalis, Ba, V, Y, Nb, Zr, Hf and elements of rare-earth group, as well as by significantly higher quantities of Ca, Mg and Cr. The depth of their formation is 10–12 km, which corresponds to the upper mantle. Conclusions. The obtained information demonstrates that fragments of two levels of the ophiolite section are tectonically aligned in the Bystrinskii massif: relatively shallow isotropic gabbros of the upper part of the ophiolite section and deep gabbros of the mantle part of the ophiolite section.
Analysis of Russia's Approach to Kyoto Protocol: Russia's Withdrawal from Second Commitment Period (2013-2020)
Authors: Ghafiel Nur Yasmin , Paramitaningrum Paramitaningrum
Published: March 2021

In 2004 Russia ratified Kyoto Protocol, one of the international agreements which focuses on climate change mitigation. Kyoto Protocol was established as a framework for countries to mitigate climate change globally by reducing their greenhouse gas emissions accordingly to their respective targets. Russia officially participated in the first commitment period of Kyoto Protocol in 2005 after ensuring the benefits by doing so. Entering the second commitment period, in 2011 Russia decided to withdraw. In consideration of Russia’s position as the largest fossil fuel energy exporter and as a country whose economy is in restoration, Russia’s approach to Kyoto Protocol is based on its interests and benefits which it gains from the framework. This paper analyzes the factors behind Russia’s withdrawal from the second commitment period of Kyoto Protocol through the perspective of offensive realism with qualitative methodology. The thesis finds that Russia’s reasoning of withdrawal was an act to protect its national interest, which is economic security, specifically its energy sector.

Two new Nearctic genera in the tribe Odynerini s. str. revealed on the bionomics and morphology, with a comment on the cocoons of the eumenine wasps (Hymenoptera: Vespidae: Eumeninae)

Published: March 2021

Two new genera are described for three species in the “red” group of the North American eumenine wasps from the genus Odynerus Latreille, 1802: Bohartodynerus Fateryga, gen. n. for O. margaretellus Rohwer, 1915 (type species) and O. cinnabarinus Bohart, 1939, and Parkerodynerus Fateryga, gen. n. (type species O. erythrogaster Bohart, 1939). Bohartodynerus cinnabarinus comb. n. is newly recorded from Nevada and New Mexico and B. margaretellus comb. n. from California, New Mexico, Utah, and Wyoming. Bionomics of the species included to these genera are summarized. Nectar robbing is reported for wasps in the genus Bohartodynerus at flowers of Astragalus spp. (Fabaceae), Penstemon sp. (Plantaginaceae), and Calylophus sp. (Onagraceae). It is speculated that nectar is used by them to bond the gravel during the construction of the closing plug of the nest. Parkerodynerus erythrogaster comb. n. apparently does not use liquid for the nest construction. Bionomics of other genera in the Odynerus group of the tribe Odynerini s. str. are discussed. Neither Bohartodynerus nor Parkerodynerus can be treated as members of the genus Odynerus according to their ethology, and the differences between these two newly described taxa are also enough to recognize them as separate genera. A cocoon of P. erythrogaster is described in detail; it has a sandwich-like structure with two layers of silk strands and a layer of sand in-between. Similar structure is found in the cocoons of other genera in the Odynerus group but only at the free part of the cocoon instead over its whole surface; that was overlooked during the previous studies of those genera.

Quantum algorithms for invariants of triangulated manifolds
Authors: Alagic Gorjan , Bering IV Edgar A.
Published: March 2021

One of the apparent advantages of quantum computers over their classical counterparts is their ability to efficiently contract tensor networks. In this article, we study some implications of this fact in the case of topological tensor networks. The graph underlying these networks is given by the triangulation of a manifold, and the structure of the tensors ensures that the overall tensor is independent of the choice of internal triangulation. This leads to quantum algorithms for additively approximating certain invariants of triangulated manifolds. We discuss the details of this construction in two specific cases. In the first case, we consider triangulated surfaces, where the triangle tensor is defined by the multiplication operator of a finite group; the resulting invariant has a simple closed-form expression involving the dimensions of the irreducible representations of the group and the Euler characteristic of the surface. In the second case, we consider triangulated 3-manifolds, where the tetrahedral tensor is defined by the so-called Fibonacci anyon model; the resulting invariant is the well-known Turaev-Viro invariant of 3-manifolds.
Loss tolerance with a concatenated graph state
Authors: Herrera-Marti David A. , Rudolph Terry
Published: March 2021

A new way of addressing loss errors is introduced which combines ideas from measurement-based quantum computation and concatenated quantum codes, allowing for universal quantum computation. It is shown that for the case where qubit loss is detected upon measurement, the scheme performs well under $23\%$ loss rate. For loss rates below $10\%$ this approach performs better than the best scheme known up to date \cite{varnava2006loss}. If lost qubits are tagged prior to measurement, it can tolerate up to $50\%$ loss. The overhead per logical qubit is shown to be significantly lower than other schemes. The obtention of the threshold is entirely analytic.
Seven Steps to Reliable Cyclic Voltammetry Measurements for the Determination of Double Layer Capacitance
Authors: Morales Dulce M. , Risch Marcel
Published: March 2021

Discovery of electrocatalytic materials for high-performance energy conversion and storage applications relies on the adequate characterization of their intrinsic activity, which is currently hindered by the dearth of a protocol for consistent and precise determination of double layer capacitance (CDL). Herein, we propose a seven-step method that aims to determine CDL reliably by scan rate-dependent cyclic voltammetry. The method considers three aspects that strongly influence the outcome of the analysis: measurement settings, data collection, and data processing. To illustrate the proposed method, two systems were studied: a resistor-capacitor electric circuit and a glassy carbon disk in an electrochemical cell. With these studies it is demonstrated that when any of the mentioned aspects of the procedure are neglected, substantial deviations of the results are observed with misestimations as large as 61% in the case of the investigated electrochemical system. Moreover, we propose allometric regression as a more suitable model than linear regression for the determination of CDL for both the ideal and the non-ideal systems investigated. We stress the importance of assessing the accuracy of not only highly specialized electrochemical methods, but also of those that are well-known and commonly used as it is the case of the voltammetric methods. The methodology proposed herein is not limited to the determination of CDL, but can be effectively applied to any other voltammetry-based analysis that aims to deliver quantitative results.
Rational Prediction of Distal Activity-Enhancing Mutations in Tryptophan Synthase

Published: March 2021

Allostery is a central mechanism for the regulation of multi-enzyme complexes. The mechanistic basis that drives allosteric regulation is poorly understood, but harbors key information for enzyme engineering. In the present study, we focus on the tryptophan synthase complex that is composed of TrpA and TrpB subunits, which allosterically activate each other. Specifically, we develop a rational approach for identifying key amino acid residues of TrpB distal from the active site. In particular, we predict positions crucial for shifting the inefficient conformational ensemble of the isolated TrpB to a productive ensemble through intra-subunit allosteric effects. The experimental validation of the new conformationally-driven TrpB design demonstrates its superior stand-alone activity in the absence of TrpA, comparable to those enhancements obtained after multiple rounds of experimental laboratory evolution. Our work evidences that the current challenge of distal active site prediction for enhanced function in computational enzyme design can be ultimately addressed.
Mimicking the Microbial Oxidation of Elemental Sulfur with a Biphasic Electrochemical Cell

Published: March 2021

The lack of an artificial system that mimics elemental sulfur (S8) oxidation by microorganisms inhibits a deep mechanistic understanding of the sulfur cycle in the biosphere and the metabolism of sulfur-oxidizing microorganisms. In this article, we present a biphasic system that mimics biochemical sulfur oxidation under ambient conditions using a liquid|liquid (L|L) electrochemical cell and gold nanoparticles (AuNPs) as an interfacial catalyst. The interface between two solvents of very different polarity is an ideal environment to oxidise S8, overcoming the incompatible solubilities of the hydrophobic reactants (O2 and S8) and hydrophilic products (H+, SO32–, SO42–, etc.). The interfacial AuNPs provide a catalytic surface onto which O2 and S8 can adsorb. Control over the driving force for the reaction is provided by polarizing the L|L interface externally and tuning the Fermi level of the interfacial AuNPs by the adsorption of aqueous anions.
Non-Covalent Assembly of Proton Donors and p-Benzoquinone Anions for Co-Electrocatalytic Reduction of Dioxygen

Published: March 2021

With weak acids (AH) at high concentrations, potential inversion can occur due to favorable hydrogen-bonding interactions with the intermediate monoanion [BQ(AH)m]•–. The solvation shell created by these interactions can mediate a proton-coupled electron transfer at more positive potentials, resulting in an overall two electron reduction ([BQ(AH)m]•– + nAH + e– ⇌ [HBQ(AH)(m+n)-1(A)]2–). Here we show that the resultant hydrogen-bonded [HBQ]– adduct mediates the transfer of electrons and the proton donor 2,2,2-trifluoroethanol (TFEOH) to a Mn-based complex during the electrocatalytic reduction of dioxygen (O2). The Mn electrocatalyst is selective for H2O2 with only TFEOH and O2 present, however, with BQ present under otherwise analogous conditions, an electrogenerated [HBQ(AH)4(A)]2– adduct (where AH = TFEOH) alters product selectivity to 96(±0.5)% H2O in a co-electrocatalytic fashion. These results suggest that hydrogen-bonded [HBQ]– dianions can function in an analogous co-electrocatalytic manner to H2Q.
Assessing the appropriateness of colorectal cancer screening in very elderly women: A cross-sectional analysis
Authors: Williams Jérôme , Fang Zhou , Grad Roland
Published: March 2021

The Canadian Task Force on Preventive Health Care recommends against screening for colorectal cancer after age 75. This recommendation is based in part on lag time to mortality benefit and a reduced life expectancy in the very elderly. To explore the extent to which screening for colorectal cancer is appropriately ordered in primary care, we performed a cross sectional study in women aged 80-84 at an academic family medicine clinic in Montreal. Appropriateness was assessed using a validated life expectancy calculator, with a 10-year life expectancy of >50% serving as the threshold for appropriateness. Among women 80-84 years of age under the care of a physician in 2016 (N=144), 95 fecal immunochemical tests were ordered from 2016-2019. Of these, 41 were screening tests, and 16/41 (39%; 95% CI 24% to 54%) were deemed to be inappropriate. This finding suggests a need to improve screening decisions for elderly women followed in primary care.

To assess the severity of major depression in relation to neutrophil-lymphocyte ratio and platelet-lymphocyte ratio. A total of 186 patients gave their consent to participate in this study. The symptoms and the severity of depression were assessed by using the “Hamilton rating scale for depression” (HAM-D). Blood samples were collected for biochemical analysis and were subjected to measure the values of neutrophils, lymphocytes, platelets, neutrophil-lymphocyte ratio and platelet-lymphocyte ratio. The mean values of neutrophil-lymphocyte ratio in mild, moderate, severe and very severely depressed individuals were found to be 1.40 (±0.24), 2.52 (±0.27), 3.53 (±0.3) & 4.39 (±0.3) respectively and it was observed that the values of neutrophil-lymphocyte ratio was increased as the severity of the depression increases (r=0.9995, p=0.0005). The mean values of platelet-lymphocyte ratio in mild, moderate, severe and very severely depressed individuals were observed to be 147.21 (±34.25), 217.83 (±12.09), 267.31 (±15.86) & 316.29 (±18.44) respectively and it was found that the values of platelet-lymphocyte ratio was increased as the severity of the depression increases (r=0.9993, p=0.0007). Increase in severity of depression positively correlated with increase in the values of both neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). Increased values of PLR showed a significant impact when compared to the values of NLR, as more than two third of the patients (71.5%) reported an increased values of PLR beyond their normal range when compared to the increased values of NLR which was just confined to only 4.8% of the study population.

Published: March 2021

Over the Counter (OTC) Drugs are legally allowed to be sold 'Over the Counter' without the prescription of a registered medical practitioner (RMP). The study aimed to assess the drug dispensing pattern of the commonly dispensed category of OTC drugs, understand the patient's knowledge using a self-designed questionnaire and to compare the cost-effectiveness based on the unit price of drugs between generic and non-generic drugs. A prospective observational study was conducted from November 2018 to April 2019 in randomly selected licensed community pharmacies in Banashankari, Bengaluru (3 private pharmacies and 1 government-sponsored pharmacy). Data collected was documented and analyzed using Microsoft Excel and Z test. 59.33% (non-generic) & 24.67% (generic) pharmacists had collected the clinical history before dispensing the drugs. Non-generic pharmacists (62.00%) provided adequate information about the dispensed drug than generic pharmacists (30.00%). The frequently dispensed OTC drugs were analgesics and antipyretics and commonly reported illness was a pain. Consumers had an opinion that the usage of OTC drugs was safe and was not aware of the side effects. Patient counselling was given to 82% of the consumers in generic and 43% in non-generic pharmacies regarding their health issue and medications. Generic drugs were more cost-effective than non-generic drugs.
