Incidence and Demographics of Post-Operative
Naloxone Administration: A 13-Year Experience
at a Major Tertiary Teaching Institution
Authors: Khelemsky Yury
Published: February 2021

Background: Perioperative use of opioids is associated with the risk of opioid-induced respiratory
depression. Naloxone is a competitive opioid antagonist typically administered to reverse opioidinduced respiratory depression. Postoperative administration of naloxone may be considered a
proxy for significant postoperative opioid-induced respiratory depression and data regarding its
use may be utilized as a quality measure. Few large studies have been done to characterize the
population and define an incidence of naloxone recipients in the postoperative inpatient setting.
Objectives: We aimed to characterize the demographics of patients receiving postoperative
naloxone, as well as the incidence of administration in the first 72 post-operative hours at a large
urban academic medical center in the United States.
Study Design: This is a retrospective cohort study.
Setting: Major urban tertiary teaching institution.
Methods: The robust electronic record database of The Department of Anesthesiology at
The Icahn School of Medicine at Mount Sinai, as well as the institution’s data warehouse were
instrumental in allowing almost 450,000 surgical cases performed between 2001 and 2014 to
be screened for naloxone administration within the first 72 postoperative hours. Organ harvests,
outside of OR intubations, cancelled cases, and patients age less than or equal to 18 were excluded
from the total case count.
Results: Naloxone was administered 433 times in a total of 442,699 postoperative cases. This
yielded an incidence of 0.1%. Additionally, the demographics of the group receiving naloxone
were described. The mean age was 60, mean body mass index (BMI) was 27, 60% were women,
and the mean American Society of Anesthesiologists (ASA) status was 3. Average time to naloxone
administration was 21 hours (standard deviation 7) after surgery. Thirteen percent of the cases were
emergent. Breakdown of anesthetic technique revealed that 81% of the cases were performed
under general anesthesia, 7% with monitored anesthesia care (MAC), and 12% under neuraxial
anesthesia. This study lays the groundwork for further elucidating risk factors for postoperative
administration of naloxone.
Limitations: This is a retrospective study.
Conclusion: The overall incidence of postoperative naloxone administration over a 13 year
period in approximately 450,000 patients was 0.1%. Demographics of this group were older, ASA
3 women, qualifying as overweight, but not obese, undergoing elective surgery with a general
anesthetic technique. Average time to administration was 21 hours postoperatively.

Associations Between Cognitive Performance
and Pain in Chronic Fatigue Syndrome:
Comorbidity with Fibromyalgia Does Matter
Authors: Ickmans Kelly
Published: February 2021

Background: In addition to the frequently reported pain complaints, performance-based
cognitive capabilities in patients with chronic fatigue syndrome (CFS) with and without
comorbid fibromyalgia (FM) are significantly worse than those of healthy controls. In various
chronic pain populations, cognitive impairments are known to be related to pain severity.
However, to the best of our knowledge, the association between cognitive performance and
experimental pain measurements has never been examined in CFS patients.
Objectives: This study aimed to examine the association between cognitive performance and
self-reported as well as experimental pain measurements in CFS patients with and without FM.
Study Design: Observational study.
Setting: The present study took place at the Vrije Universiteit Brussel and the University of
Antwerp.
Methods: Forty-eight (18 CFS-only and 30 CFS+FM) patients and 30 healthy controls
were studied. Participants first completed 3 performance-based cognitive tests designed to
assess selective and sustained attention, cognitive inhibition, and working memory capacity.
Seven days later, experimental pain measurements (pressure pain thresholds [PPT], temporal
summation [TS], and conditioned pain modulation [CPM]) took place and participants were
asked to fill out 3 questionnaires to assess self-reported pain, fatigue, and depressive symptoms.
Results: In the CFS+FM group, the capacity of pain inhibition was significantly associated
with cognitive inhibition. Self-reported pain was significantly associated with simple reaction
time in CFS-only patients. The CFS+FM but not the CFS-only group showed a significantly
lower PPT and enhanced TS compared with controls.
Limitations: The cross-sectional nature of this study does not allow for inferences of
causation.
Conclusions: The results underline disease heterogeneity in CFS by indicating that a measure
of endogenous pain inhibition might be a significant predictor of cognitive functioning in
CFS patients with FM, while self-reported pain appears more appropriate to predict cognitive
functioning in CFS patients without FM.

Treatment of Abdominal Segmental Hernia,
Constipation, and Pain Following Herpes Zoster
with Paravertebral Block
Authors: Jeon Younghoon
Published: February 2021

Herpes zoster (HZ) most commonly occurs in elderly patients and involves sensory neurons resulting in
pain and sensory changes. Clinically significant motor deficits and visceral neuropathies are thought
to be relatively rare. A 72-year-old man presented with abdominal segmental hernia, constipation,
and pain following HZ in the left T9-10 dermatome. Sixteen days before presentation, he had
developed a painful herpetic rash in the left upper abdominal quadrant. Approximately 10 days
after the onset of the rash, constipation occurred and was managed with daily oral medication with
bisacodyl 5 mg. In addition, 14 days after the onset of HZ, the patient noticed a protrusion of the left
upper abdominal wall. Abdominal x-ray, ultrasound of the abdomen, and electrolyte analysis showed
no abnormalities. General physical examination revealed a reducible bulge in his left upper quadrant
and superficial abdominal reflexes were diminished in the affected region. Electromyographic testing
revealed denervational changes limited to the left thoracic paraspinal muscles and supraumbilical
muscles, corresponding to the affected dermatomes. He was prescribed with 500 mg of famciclovir
3 times a day for 7 days, and pregabalin 75 mg twice a day and acetaminophen 650 mg 3 times a
day for 14 days. However, his pain was rated at an intensity of 5 on the numerical analogue scale
from 0 (no pain) to 10 (worst pain imaginable). A paravertebral block was performed at T9-10
with a mixture of 0.5% lidocaine 3 mL and triamcinolone 40 mg. One day after the procedure, the
abdominal pain disappeared. In addition, 5 days after the intervention, the abdominal protrusion and
constipation were resolved. He currently remains symptom free at a 6 month follow-up.

Computed Tomography-Guided Radiofrequency
Thermocoagulation of the Gasserian Ganglion
Using an Alternative to Hartel Anterior Approach:
A Bicentral Study
Authors: Filippiadis Dimitrios K.
Published: February 2021

Background: Trigeminal neuralgia (TN) is associated with multiple mechanisms involving
peripheral and central nervous system pathologies. Among percutaneous treatments offered,
radiofrequency thermocoagulation (RFT) is associated with longer duration of pain relief. Mostly
due to anatomic variation, cannulation of the foramen ovale using the Hartel approach has a
failure rate of 5.17%.
Objectives: To report safety and efficacy of continuous RFT with an alternative to Hartel anterior
approach under computed tomography (CT) guidance in patients with classic TN.
Study Design: Retrospective institutional database review; bicentral study.
Setting: Although this was a retrospective database research, institutional review board approval
was obtained.
Methods: Institutional database review identified 10 patients (men 8, women 2) who underwent
CT-guided RFT of the Gasserian ganglion. Preoperational evaluation included physical examination
and magnetic resonance imaging. Under anesthesiology control and local sterility measures, a
radiofrequency needle was advanced, and its approach was evaluated with sequential CT scans.
Motor and sensory electrostimulation tests evaluated correct electrode location. Pain prior, 1 week,
1, 3, and 6 months after were compared by means of a numeric visual scale (NVS) questionnaire.
Results: Mean self-reported pain NVS score prior to RFT was 9.2 ± 0.919 units. One week after
the RFT mean NVS score was 1.10 ± 1.287 units (pain reduction mean value of 8.1 units). At 3 and
6 months after thermocoagulation the mean NVS score was 2.80 ± 1.549 units and 2.90 ± 1.370
units, respectively. There were no postoperative complications. Three patients experienced facial
numbness, which gradually resolved over a period of 1 month.
Limitations: Retrospective nature; small number of patients; lack of a control group undergoing
a different treatment of TN.
Conclusions: Percutaneous CT-guided RFT of the Gasserian ganglion constitutes a safe and
efficacious technique for the treatment of TN, with significant pain relief and minimal complication
rates improving life quality in this group of patients.

The Effect of COVID-19 on Interventional Pain
Management Practices: A Physician Burnout
Survey
Authors: Soin Amol
Published: February 2021

Background: Burnout has been a commonly discussed issue for the past ten years among
physicians and other health care workers. A survey of interventional pain physicians published in
2016 reported high levels of emotional exhaustion, often considered the most taxing aspect of
burnout. Job dissatisfaction appeared to be the leading agent in the development of burnout in
pain medicine physicians in the United States. The COVID-19 pandemic has drastically affected the
entire health care workforce and interventional pain management, with other surgical specialties,
has been affected significantly. The COVID-19 pandemic has placed several physical and emotional
stressors on interventional pain management physicians and this may lead to increased physician
burnout.
Objective: To assess the presence of burnout specific to COVID-19 pandemic among practicing
interventional pain physicians.
Methods: American Society of Interventional Pain Physicians (ASIPP) administered a 32 question
survey to their members by contacting them via commercially available online marketing company
platform. The survey was completed on www.constantcontact.com.
Results: Of 179 surveys sent, 100 responses were obtained. The data from the survey
demonstrated that 98% of physician practices were affected by COVID and 91% of physicians
felt it had a significant financial impact. Sixty seven percent of the physicians responded that inhouse billing was responsible for their increased level of burnout, whereas 73% responded that
electronic medical records (EMRs) were one of the causes. Overall, 78% were very concerned.
Almost all respondents have been affected with a reduction in interventional procedures. 60%
had a negative opinion about the future of their practice, whereas 66% were negative about the
entire health care industry.
Limitations: The survey included only a small number of member physicians. Consequently, it
may not be generalized for other specialties or even pain medicine. However, it does represent the
sentiment and present status of interventional pain management.
Conclusion: The COVID-19 pandemic has put interventional pain practices throughout the
United States under considerable financial and psychological stress. It is essential to quantify
the extent of economic loss, offer strategies to actively manage provider practice/wellbeing, and
minimize risk to personnel to keep patients safe.

Overview of Stem Cell Therapy for Acute
Respiratory Distress Syndrome with Focus on
COVID 19
Authors: Kaye Rachel
Published: February 2021

Objective: There are as yet no effective strategies to treat the novel COVID-19 and to stem its
symptoms, including ARDS. This review examines recent research studies in humans to determine
whether mesenchymal stem cells (MSCs) may be used effectively and safely to target potentially
deadly lung damage that may follow infection.
Methods: A literature search was conducted to find published manuscripts on the treatment of
ARDS and COVID-19 symptoms, disease presentation, and available treatment regimens. Electronic
data bases of scientific articles and records of printed documents of JAMA journals were searched to
find research publications on MSC treatment of ARDS and COVID-19. Outcome variables included
mortality over varying time periods, hospital days, days on ventilator, and biological factors.
Results: Two randomized double-blind clinical trials, 2 pilot studies, and 2 case reports described
MSC use to treat ARDS with specific focus on COVID-19 and lung symptoms of cytokine storm.
The MSCs were well-tolerated across studies. No significant differences in treatment outcome were
found in randomized double-blind trials; however, results of 1 pilot study and 1 case report showed
that MSCs led to lung symptom resolution and survival in severely ill treatment patients.
Conclusions: There is little published research on disease and survival outcomes among patients
suffering severe lung disease associated with ARDS and COVID-19, and studies available are limited
by lack of consistency in design and numerous flaws and limitations. Comparisons across studies
are difficult. Nevertheless, it is documented that 8 ARDS patients with COVID-19 experienced
symptom recovery and survival subsequent to MSC administration. MSCs are potentially life-saving
treatment approaches for some patients who exhibit severe lung distress and have not responded
to standard treatments. This is an obviously exciting research and treatment option for COVID-19
and other life-threatening diseases.

DISEASE
Authors: Das Brahmarshi , Hait Narendranath , Biswas Titol , Jana Debarshi
Published: February 2021

INTRODUCTION: Chronic Kidney Disease (CKD) is dened as a disease characterized by alterations in either kidney
structure or function or both for a minimum of 3 months duration. According to the National Kidney Foundation criteria,
1 CKD has been classied into ve stages with stage 1 being the earliest or mildest CKD state and stage 5 being the most severe CKD stage. To
stage CKD, it is necessary to estimate the GFR rather than relying on serum creatinine concentration. Glomerular ltration rate (GFR), either
directly measured by computing urinary clearance of ltration marker such as inulin or estimated by calculating from different equations using
serum creatinine. is the most commonly used parameter to assess kidney function.
AIM AND OBJECTIVES: a) Establish relationship between serum CKD and eGFR
MATERIAL AND METHOD: A Cross-sectional study on 100 cases of newly diagnosed Chronic Kidney Disease patients and matched control
subjects is undertaken to study.100 Patients who are newly diagnosed as CKD are selected after proper initial screening.
RESULT AND ANALYSIS: In case, the mean eGFR (mean± s.d.) of patients was 25.1500 ± 11.8929. In control, the mean eGFR (mean± s.d.) of
patients was 87.2200 ± 17.8295. Difference of mean eGFR in two groups was statistically signicant (p<0.0001). In case, the mean creatinine
(mean± s.d.) of patients was 3.6350 ± 2.4419 mg/dl. In control, the mean creatinine (mean± s.d.) of patients was .9435 ± .1317 mg/dl. Difference
of mean creatinine in two groups was statistically signicant (p<0.0001).
CONCLUSION: eGFR was strongly associated with CKD that also statistically signicant. The positive correlation was found in eGFR.

Buchholzia coriacea is a plant of the Congolese pharmacopeia. Her barks of trunk were the subject of aphrodisiac study in
our laboratory. But her effect on the arterial pressure, the cardiac frequency and on the contractions of the heart, remain
even unknown. This is how the present work aims the assessment of the cardiovascular potential of the barks of trunk of this plant at the albino
male rat.
The effects on the mean arterial pressure and the cardiac frequency at the rat normotended have been valued by the method invasive whereas the
classic model of drip of isolated heart of batrachian has been used to value the effects on the heart isolated of toad. The administration of the
aqueous extract of the barks of trunk of B. coriacea (10, 20 and 40 mg/kg, i.v) decreases the mean arterial pressure and the cardiac frequency as
the yohimbine(1mg/kg, i.v) and the µg acetylcholine (50 µg / Kg, i.v).This effects hypotensor and negative chronotrope are raised completely by
the atropine (1 mg / kg. i.v), ce that conrms the implication of the receiving muscarinics in the mechanism of action of this extract. To the
concentrations of 2; 2,5 and 3 mg / ml extracts it aqueous of the barks of trunk of B. coriacea decreases strength and the frequency of the
contractions of the heart isolated of toad and to 4 and 5 mg/ml, it drags to a reversible stop of the contractions of the heart isolated of toad.
An ecologically valid examination of event-based and time-based prospective memory using immersive virtual reality: the effects of delay and task type on everyday prospective memory.

Published: February 2021

Recent research has focused on assessing either event- or time-based prospective memory (PM) using laboratory tasks. Yet, the findings pertaining to PM performance on laboratory tasks are often inconsistent with the findings on corresponding naturalistic experiments. Ecologically valid neuropsychological tasks resemble the complexity and cognitive demands of everyday tasks, offer an adequate level of experimental control, and allow a generalisation of the findings to everyday performance. The Virtual Reality Everyday Assessment Lab (VR-EAL), an immersive virtual reality neuropsychological battery with enhanced ecological validity, was implemented to comprehensively assess everyday PM (i.e., focal and non-focal event-based, and time-based). The effects of the length of delay between encoding and initiating the PM intention and the type of PM task on everyday PM performance were examined. The results revealed that everyday PM performance was affected by the length of delay rather than the type of PM task. The effect of the length of delay differentially affected performance on the focal, non-focal, and time-based tasks and was proportional to the PM cue focality (i.e., semantic relationship with the intended action). This study also highlighted methodological considerations such as the differentiation between functioning and ability, distinction of cue attributes, and the necessity of ecological validity.

How to Make Phoenix to Arise from the Ashes: Brand Loyalty as a Prospective Pillar of Branding in Tourism after Crisis COVID-19
Authors: Majerova Jana , Fernandes Carlos
Published: February 2021

Current global situation has radically examined the applicability of many managerial patterns which have been created so far. The reason is that crisis COVID-19 has changed not only established frameworks of managerial practice but also functional frameworks of consumer behaviour. There is no guaranty of occurring forecasted scenarios of market development. Black swan has flown also over the brands which have been traditionally perceived as valuable. So, the aim of this paper is to discuss brand loyalty as a prospective pillar of brand value resuscitation in tourism and to identify relevant brand value sources significant to brands characterised by loyalty. On the case study of Slovak consumer perception of brand value sources, it is possible to verify so far formulated postulates and modified theories, which take into account relevance of national psychographic specifics. Primary data used in the presented study were obtained by our own survey carried out on the sample of 2,000 respondents. The given data were statistically evaluated by the factor analysis supported by implementation of KMO Test, Barlett's test of sphericity and calculation of Cronbach's Alpha for relevant brand loyalty sources in tourism. By providing this statistical evaluation of the results, it has been possible to identify relevant brand value sources which are suitable to modify methodological apparatus of brand value building and management.
Importance of Advertising Media Attributes in the Context of Long-Term Brand Building in Slovakia
Authors: Kicova Eva
Published: February 2021

The aim of this paper is to understand which attributes Slovak marketers consider to be the most important and consequently which media they perceive to meet those requirements best. The first part of the analysis represents the answer to the supporting research question: What do Slovak marketers consider to be the most important attributes of the advertising medium in delivering a brand building campaign. The relative importance of attributes was evaluated using MaxDiff analysis where respondents were asked to trade off the most and least important attributes in 9 different combinations of 4 attributes at the time. The responses were analysed using a simple count-based approach, which is concerned with an overall number of -term brand building when the respondent was forced to make a choice between attributes. The purpose of this article is to help Slovak marketers become aware of their current perception of advertising media and whether this perception needs to be re-evaluated in order to prevent potential negative long-term consequences of incorrect media decisions as experienced in other countries. Therefore, this paper aims to assess the current state of the Slovak advertising industry in terms of ability to evaluate the effectiveness of advertising media to grow brand in a long-term by identifying the most important attributes Slovak marketers consider when choosing media for a brand campaign.

Procedural Errors in the Evidentiary Process and Their Impact on Criminal Proceedings in the Slovak Republic
Authors: Mokra Ivana
Published: February 2021

The lawful procedure in evidentiary process is a conditio sine qua non of the admissibility of evidence. In other words, it is a necessary condition for the admission of evidence in criminal proceedings. The violation of this condition leads to procedural errors leading to the unlawfulness of the evidence, as a result of which the accused may be acquitted. For this reason, it's the aim of this article, not only to define the procedural errors, whose incidence is particularly noticeable in providing evidence by law enforcement authorities involved in criminal proceedings, but also to analyse their impact on the outcome of the criminal proceedings, i.e. the decision about the guilt and punishment of the accused and on the basis of a specific example, to point out shortcomings which would be appropriate to prevent de lege ferenda. The presented article provides, on the one hand, a brief insight into the basic terminology related to the mentioned topic, explains the content and purpose of the legislation and on, the other hand, acquires more practical view, based on an analysis of selected example of procedural error in evidentiary process.

ELECTROMOBILITY TOPICS ENTERING A NEW DECADE
Authors: POPESCU Liviu
Published: February 2021

During the last ten years the electric vehicles became more and more part of the daily mobility. Supported by different policies, but also by the technology advance, the electromobility is far to be an achieved topic and enters a new decade. The hybrid solutions continue to offer an alternative using the combustion engines. Latest researches and developments on fuel cells push to an alternative future, based on hydrogen. The electric batteries, as energy storage on vehicle, remain the most important way to conduct EV to the roads, with regular improvements. In fact, all these technologies are developing solutions to provide and control the energy for an electric motor. The classic solution using one engine and a kinematic chain to distribute the mechanical power to the wheels is completed by the possibility to integrate not only one, but more electric motors in the same vehicle.
THE ANALYSIS OF THE THREE-PHASE INDUCTION MOTOR WITH DEEP ROTOR BARS THROUGH NUMERICAL SIMULATIONS UTILIZING A MODIFIED MATHEMATICAL MODEL
Authors: IORDACHE Mihai , DELEANU Sorin , GALAN Neculai
Published: February 2021

The three-phase induction machine mathematical model presented in the paper, is adequate for applying to the deep rotor bars case. The rotor resistance R’r(r), respectively its leakage inductivity L’r(r), depend upon the rotor currents’ frequency fr because of the skin effect. Following the previous considerations, one developed slip dependent analytical expressions of the rotor circuit resistance R’r(s), respectively rotor circuit leakage reactance L’r (s). A modified space phasor based mathematical model of the deep bar induction motor is tested through simulations to assess the motor’s characteristics. The results are in accordance with the literature.
CALCULUL CÂMPULUI ELECTRIC ASOCIAT UNUI CUPLOR INDUCTIV DESTINAT TRANSFERULUI DE PUTERE WIRELESS
Authors: TUDORACHE Tiberiu , MARINESCU Andrei
Published: February 2021

"Contactless or wireless power transmission has become a widespread disruptive technology. Although known for more than 100 years, it is the result of the unprecedented development of microelectronics and power electronics in recent decades. Numerous technical solutions for near-field energy transmission at different power and frequency levels are currently established: capacitive electric field transmission (CPT), inductive magnetic field transmission (IPT), multi-coil transmission and simultaneous transmission via electric field and magnetic field as a combination of the first two. The materialization of the contactless transmission is achieved in theory and practice through different types of contactless coupling circuits, generically called ""contactless couplers"". The inductive coupler can be considered as an electrical transformer in air or with open magnetic circuit in which the primary (Tx) and the secondary winding (Rx) can occupy different positions from each other depending on the application [1]. It is considered a representative element for WPT (Wireless Power Transfer) systems currently used from transferred powers of several watts to tens or hundreds of kilo-watts. To increase the transfer efficiency, the coupler works at high frequencies, of the order of kHz or MHz and in some cases has planar windings, of different shapes, made of litz wire and usually has magnetic flux concentrators [2]. Any inductive coupler is integrated into a complex transmission system, consisting of many other components [3].
In addition to the electromagnetic calculation widely presented in other works, open magnetic circuit construction produces electric and magnetic scattering fields that have a negative effect on both electrical and electronic equipment in the vicinity and on human health if the exposure exceeds certain thresholds. These thresholds are indicated by international standards and requirements [4-5] achieved by applying the precautionary principle [6] so that they can be reviewed periodically and are not mandatory unless they are taken over in national law.
In this paper we analyze by the finite element method, in approximate 2D, the electric field produced by an inductive coupler in various simplified construction variants and calculate certain related quantities of practical importance such as: electric field distribution in the field of calculation, electric field strength in the vicinity of the inductive coupler, equipotential lines, reactive power, equivalent capacities."

With the economic development, transportation in the city becomes more crowded. Furthermore, fuel consumption is causing a serious problem of pollution in the urban environment. Hybrid electric vehicles are considered as a good solution compared to conventional internal combustion engine vehicles. In order to solve those problems, the components parameters of a series hybrid electric vehicle are selected and tested with the ADvanced VehIcle SimulatOR (ADVISOR) simulation tool, which is a software-based on Matlab_simulink. Then, an optimisation was done to minimise simultaneous fuel consumption and emissions (HC, CO, and NOx) of the vehicle engine. In addition, the driving performance requirements are also examined during the urban dynamometer driving schedule (UDDS) to fix their optimal control parameters. Finally, the results show that those steps help reduce fuel consumption and emissions while guaranteeing vehicle performance. Hence, the series hybrid electric vehicle greatly improves fuel economy and reduces toxic emissions.

Fused deposition modeling (FDM) is an additive manufacturing method that offers numerous benefits in terms of simplicity, ease of operation, material strength, flexibility, etc. However, its fabricated parts have frequently been affected by poor dimensional and geometrical accuracy. It is, therefore, extremely crucial to examine the numerous causes of errors in FDM so that appropriate steps can be taken to address its limitations. In this work, an attempt has been made to quantify the various sources of errors that contribute to the poor accuracy of FDM fabricated parts. For this reason, a standard part (also referred to as benchmark part), which is comprised of various shapes, features, and geometries, was used for the evaluation of the FDM process. The predominant goal of this research was to characterize the FDM process in terms of dimensions and geometrical accuracy. Although this research was specific to a particular machine, it provided useful information regarding the procedure that can be employed whenever a benchmark part will be utilized. This work can also act as a foundation to further improvement to the FDM machine design and expansion of its applications.

Medical data classification is used to find the hidden patterns of data by training a large amount of patient data collected from the providers. As the medical data is very sensitive, it must be a safeguard from all the noncollaborative means. Thus, it is important to take steps to preserve the confidential medical data. Accordingly, this paper proposes a classification method termed as crow optimization-based deep belief neural network (CS-DBN) to preserve the privacy of confidential medical data automatically. This classifier works based on three phases, including generation of the privacy-preserved data, construction of ontology, and classification. The Deep convolutional kernel approach is used to provide data confidentiality using the optimal coefficients. The construction of ontology is done with the cardiac heart disease terms used in the medical field for classification. Finally, the classification is performed using the deep belief network (DBN), which is trained using the crow search algorithm (CSA). The performance is analyzed in terms of the metrics, namely, accuracy, fitness, sensitivity, and specificity. The proposed CS-DBN method produces higher fitness, accuracy, sensitivity, and specificity of 0.9007, 0.8842, 1, and 0.8408, respectively.

Diabetic retinopathy (DR) is the major reason of vision loss in the active population. It can usually be prevented by regulating the blood glucose and providing a timely treatment. DR has clinical features recognized by the experts including the blood vessel area, exudates, neovascularization, hemorrhages, and microaneurysm. Because DR has some varieties and complexities due to its geometrical and haemodynamic features, it is hard and time-consuming to detect DR in manual diagnosis. In Computer Aided Diagnosis (CAD) systems, the features of DR fundus images are detected using computer vision techniques. In this paper, a CAD system is proposed, which distinguishes automatically whether the fundus is normal or it suffers from diabetic retinopathy disease. As preprocess morphological operations like filtering, opening, and dilation are applied to the images firstly, then, Optic Disk (OD) segmentation is implemented using Greedy algorithm. Because of the intensity of an OD is similar to some DR intensities, OD regions are removed from the fundus images for an accurate feature extraction. The features extracted with Curvelet Transform (CT) and Scale Invariant Feature Transform (SIFT), respectively, are concatenated to provide a feature set that defines the fundus data optimally. Finally, the feature set is given to the Support Vector Machines (SVM), K-Nearest Neighborhood (KNN), and Naïve–Bayes (NB) classifiers for the DR identification purpose. The proposed method achieves the highest accuracy and sensitivity as 92.8% and 97.6%, respectively, with SVM and specificity as 92.5% with KNN classifier.

Published: February 2021

The assessment of secondary school success is according to the number of students they are producing to join universities and other higher learning institutions. To increase access to all pupils from primary schools to access secondary schools, the government of Kenya upgraded previously extra county schools to national status to ensure regional distribution of schools across the nation. With the upgrade, the government was required to inject funds to enable facilities expansion. Despite the upgrade, the money allocated and disbursed to schools has always been inadequate to meet the needs of students. Therefore, this demands that school management makes plans for financial mobilisation to ensure that school operations are done without interruptions. The paper looks at the financial resource planning strategies that upgraded national schools in western Kenya have in place for the purpose of improving their performance. Data was collected from eight of the upgraded schools making up the study population where principals and teachers were the respondents. A sample of 156 respondents was selected to answer research questions through interviews and questionnaires. Analysis of data was performed using quantitative and qualitative methods. SPSS facilitated quantitative data analysis. The study found out that schools experienced financial shortfall arising from inadequate capitation grants from the government and delay in payment of schools by students. To cushion themselves, schools had made several financial plans like applying for grants for infrastructure development. Further, despite schools having large tracts of land, some school management did not put into use either through growing grass for dairy farming or planting crops for subsidising school food supplies. Computed correlation statistics showed a weak correlation that existed (r=0.191 and p=0.016) between financial planning dynamics and academic performance of upgraded national schools in the western region of Kenya. The paper concludes that financial resource planning strategies had minimal effects on the academic performance of upgraded national secondary schools in Kenya Certificate of Secondary examinations. The paper recommends that there is a need for school administration to work with stakeholders to identify profitable projects that can be implemented in their school to earn income.
