  • Enhancing Tumor Detection in IR-UWB Breast Cancer System

    • Abstract: An ultra-wideband (UWB) microwave system for breast cancer detection is presented. The proposed system includes monocycle pulse generator, antipodal Vivaldi antenna, breast model, and calibration algorithm for tumor detection. Firstly, our pulse generator employs transmission gate in glitch generator to achieve several advantages such as low power consumption and low ringing level. Secondly, the antipodal Vivaldi antenna is designed assuming FR4 dielectric substrate material, and developed antenna element ( mm2) features a − dB return loss and bandwidth ranges from 2.3 GHz to more than 11 GHz. Thirdly, the phantom breast can be modeled as a layer of skin, fat, and then tumor is inserted in this layer. Finally, subtract and add algorithm (SAD) is used as a calibration algorithm in tumor detection system. The proposed system suggested that horizontal antenna position with 90° between transmitting and receiving antennas is localized as a suitable antenna position with different rotating location and a 0.5 cm near to phantom. The mean advantages of this localization and tracking position around breast is a high received power signal approximately around mv as a higher recognized signal in tumor detection. Using our proposed system we can detect tumor in 5 mm diameter.

  • Comprehensive Histological and Immunochemical Forensic Studies in Deaths
           Occurring in Custody

    • Abstract: In-custody deaths have several causes, and these include homicide, suicide, natural death from chronic diseases, and unexplained death possibly related to acute stress, asphyxia, excited delirium, and drug intoxication. In some instances, these deaths are attributed to undefined accidents and natural causes even though there is no obvious natural cause apparent after investigation. Understanding these deaths requires a comprehensive investigation, including documentation of circumstances surrounding the death, review of past medical history, drug and toxicology screens, and a forensic autopsy. These autopsies may not always clearly explain the death and reveal only nonspecific terminal events, such as pulmonary edema or cerebral edema. There are useful histologic and biochemical signatures which identify asphyxia, stress cardiomyopathy, and excited delirium. Identifying these causes of death requires semiquantitative morphologic and biochemical studies. We have reviewed recent Bureau of Justice Statistics on in-custody death, case series, and morphological and biochemical studies relevant to asphyxia, stress cardiomyopathy, and excited delirium and have summarized this information. We suggest that regional centers should manage the investigation of these deaths to provide more comprehensive studies and to enhance the expertise of forensic pathologists who would routinely manage potentially complex and difficult cases.

  • Computational Acoustic Beamforming for Noise Source Identification for
           Small Wind Turbines

    • Abstract: This paper develops a computational acoustic beamforming (CAB) methodology for identification of sources of small wind turbine noise. This methodology is validated using the case of the NACA 0012 airfoil trailing edge noise. For this validation case, the predicted acoustic maps were in excellent conformance with the results of the measurements obtained from the acoustic beamforming experiment. Following this validation study, the CAB methodology was applied to the identification of noise sources generated by a commercial small wind turbine. The simulated acoustic maps revealed that the blade tower interaction and the wind turbine nacelle were the two primary mechanisms for sound generation for this small wind turbine at frequencies between 100 and 630 Hz.

  • Orthodontic Management in Aggressive Periodontitis

    • Abstract: Aggressive periodontitis is a type of periodontitis with early onset and rapid progression and mostly affecting young adults who occupy a large percentage of orthodontic patients. The role of the orthodontist is important in screening the disease, making a provisional diagnosis, and referring it to a periodontist for immediate treatment. The orthodontist should be aware of the disease not only before starting the appliance therapy, but also during and after the active mechanotherapy. The orthodontic treatment plan, biomechanics, and appliance system may need to be modified to deal with the teeth having reduced periodontal support. With proper force application and oral hygiene maintenance, orthodontic tooth movement is possible without any deleterious effect in the tooth with reduced bone support. With proper motivation and interdisciplinary approach, orthodontic treatment is possible in patients with controlled aggressive periodontitis.

  • Consistency Test between Scoring Systems for Predicting Outcomes of
           Chronic Myeloid Leukemia in a Saudi Population Treated with Imatinib

    • Abstract: Inconsistency in prognostic scores occurs where two different risk categories are applied to the same chronic myeloid leukemia (CML) patient. This study evaluated common scoring systems for identifying risk groups based on patients’ molecular responses to select the best prognostic score when conflict prognoses are obtained from patient profiles. We analyzed 104 patients diagnosed with CML and treated at King Abdulaziz Medical City, Saudi Arabia, who were monitored for major molecular response (achieving a BCR-ABL1 transcript level equal to or less than 0.1%) by Real-Time Quantitative Polymerase Chain Reaction (RQ-PCR), and their risk profiles were identified using Sokal, Hasford, EUTOS, and ELTS scores based on the patients’ clinical and hematological parameters at diagnosis. Our results found that the Hasford score outperformed other scores in identifying risk categories for conflict groups, with an accuracy of 63%.

  • Translation and Validation of Modified Dental Anxiety Scale: The Nepali
           Version

    • Abstract: Introduction. For proper management of anxious dental patients it is imperative to assess their levels of dental anxiety before treatment. Modified Dental Anxiety Scale (MDAS) is the most commonly used questionnaire to assess dental anxiety. But a Nepali version of MDAS is still lacking. Hence, the objective of this study was to develop a reliable and valid Nepali version of MDAS. Materials and Methods. The English version of the MDAS was translated into Nepali following a forward and backward translation process. Following pretesting and cognitive interviewing a final version of Nepali questionnaire was obtained. One hundred and fifty patients attending Department of Orthodontics completed the Nepali version of MDAS questionnaire at their convenience. Also, patients were asked to rate their overall anxiety on a 100 mm visual analog scale (VAS). A test-retest of the questionnaire was performed with 30 patients after 2 weeks. Results. Cronbach’s alpha value of the Nepali version of MDAS was 0.775. The Intraclass Correlation Coefficient between test and retest was 0.872. Spearman’s correlation coefficient between the total MDAS score and VAS score was 0.838. Conclusion. The translated Nepali version of MDAS is a reliable and valid instrument to measure the dental anxiety of Nepali patients.

  • A Tool to Simulate the Transmission, Reception, and Execution of
           Interactive TV Applications

    • Abstract: The emergence of Interactive Digital Television (iDTV) opened a set of technological possibilities that go beyond those offered by conventional TV. Among these opportunities we can highlight interactive contents that run together with linear TV program (television service where the viewer has to watch a scheduled TV program at the particular time it is offered and on the particular channel it is presented on). However, developing interactive contents for this new platform is not as straightforward as, for example, developing Internet applications. One of the options to make this development process easier and safer is to use an iDTV simulator. However, after having investigated some of the existing iDTV simulation environments, we have found a limitation: these simulators mainly present solutions focused on the TV receiver, whose interactive content must be loaded in advance by the programmer to a local repository (e.g., Hard Drive, USB). Therefore, in this paper, we propose a tool, named BiS (Broadcast iDTV content Simulator), which makes possible a broader solution for the simulation of interactive contents. It allows simulating the transmission of interactive content along with the linear TV program (simulating the transmission of content over the air and in broadcast to the receivers). To enable this, we defined a generic and easy-to-customize communication protocol that was implemented in the tool. The proposed environment differs from others because it allows simulating reception of both linear content and interactive content while running Java applications to allow such a content presentation.

  • Efficient Data Transfer Rate and Speed of Secured Ethernet Interface
           System

    • Abstract: Embedded systems are extensively used in home automation systems, small office systems, vehicle communication systems, and health service systems. The services provided by these systems are available on the Internet and these services need to be protected. Security features like IP filtering, UDP protection, or TCP protection need to be implemented depending on the specific application used by the device. Every device on the Internet must have network interface. This paper proposes the design of the embedded Secured Ethernet Interface System to protect the service available on the Internet against the SYN flood attack. In this experimental study, Secured Ethernet Interface System is customized to protect the web service against the SYN flood attack. Secured Ethernet Interface System is implemented on ALTERA Stratix IV FPGA as a system on chip and uses the modified SYN flood attack protection method. The experimental results using Secured Ethernet Interface System indicate increase in number of genuine clients getting service from the server, considerable improvement in the data transfer rate, and better response time during the SYN flood attack.

Two independent reviewers selected eligible publications based on inclusion/exclusion criteria. Quantitative studies published since 1985 were included. Thirty-six studies were included in the final review. Individual level barriers included sociodemographic characteristics, such as being a male, of young age and low education level, risk behaviours such as injecting drugs, having multiple sexual partners, and psychosocial factors. Older age, higher education level, being a woman, having high self-esteem, having coping skills, and holding insurance coverage were identified as facilitators. Interpersonal barriers and facilitators were linked to risk behaviours of sexual partners. Contextual barriers included essentially the HIV testing center and its characteristics. This review identified the most important factors that need to be addressed to ensure that people return for their HIV test results.

  • A New Class of Almost Ricci Solitons and Their Physical Interpretation

    • Abstract: We establish a link between a connection symmetry, called conformal collineation, and almost Ricci soliton (in particular Ricci soliton) in reducible Ricci symmetric semi-Riemannian manifolds. As a physical application, by investigating the kinematic and dynamic properties of almost Ricci soliton manifolds, we present a physical model of imperfect fluid spacetimes. This model gives a general relation between the physical quantities of the matter tensor of the field equations and does not provide any exact solution. Therefore, we propose further study on finding exact solutions of our viscous fluid physical model for which it is required that the fluid velocity vector be tilted. We also suggest two open problems.

  • The Association of Hepatitis C Serological Status with Several Risk
           Factors in Indonesia

    • Abstract: Hepatitis is an inflammation of the liver commonly caused by viral infection such as hepatitis A, B, C, D, and E but it is also possible by other causes. Infection with hepatitis C virus is also referred to as a disguise because the early infection is often asymptomatic that often goes undetected. This study aims at determining the several associated risk factors with hepatitis C serological status. The study design is cross-sectional. The biomedical data collection was carried out in 33 provinces in Indonesia with a population in urban blocks, census in Indonesia, where the sample is all household members over the age of one year from selected households by signing the informed consent. Total block census in selected urban area is about 971-block census with a total sample of 15.536 households. The results showed that there is a correlation between hepatitis C serological statuses with demographic group and that the age and occupation groups showed significant value obtained at 0.001 (OR = 3.27, CI = 1.84–5.81) and 0.209 (OR = 0.23, CI = 0.59–0.94). In conclusion, there are risk factors such as age and occupation that have a correlation of being infected with hepatitis C serological status.

  • The Impact of Duodenal Diverticuli and the Execution of Endoscopic
           Retrograde Cholangiopancreaticography

    • Abstract: Introduction. Duodenal diverticuli alter the anatomy of the papillary region and can make an ERCP difficult. Aim. To study the outcome of ERCP in cases of duodenal diverticuli. Patients and Methods. Consecutive ERCPs in a period of 24 years were included. Endoscopy reports were studied for presence of diverticuli. Success of the procedure and findings were noted. Clinical records were searched for clinical presentation of the patient. Patients without duodenal diverticuli were used as comparison. Results. 2795 procedures were done in 2092 patients. Of these, 211 (10%) had diverticuli. Diverticuli occurred significantly more often in women (). ERCP was significantly more often inconclusive in cases of a diverticulum, 12.8% versus 6.3%, . In cases of a successful ERCP, patients with diverticuli showed more often no abnormalities in the bile duct, 26% versus 17%, . In 64% of cases, the reason for ERCP was cholestasis. There was no significant difference in presence of stones or cholangitis. Biliary pancreatitis was seen more often in patients without diverticuli, 4.4% versus 1.4%, . This was also the case for malignancies, 18.5% versus 6.6%, . Conclusion. It is concluded that duodenal diverticuli can be responsible for cholestasis. Presence of a diverticulum in the duodenum makes the ERCP procedure more complex.

  • The Impact of Variable Wind Shear Coefficients on Risk Reduction of Wind
           Energy Projects

    • Abstract: Estimation of wind speed at proposed hub heights is typically achieved using a wind shear exponent or wind shear coefficient (WSC), variation in wind speed as a function of height. The WSC is subject to temporal variation at low and high frequencies, ranging from diurnal and seasonal variations to disturbance caused by weather patterns; however, in many cases, it is assumed that the WSC remains constant. This assumption creates significant error in resource assessment, increasing uncertainty in projects and potentially significantly impacting the ability to control gird connected wind generators. This paper contributes to the body of knowledge relating to the evaluation and assessment of wind speed, with particular emphasis on the development of techniques to improve the accuracy of estimated wind speed above measurement height. It presents an evaluation of the use of a variable wind shear coefficient methodology based on a distribution of wind shear coefficients which have been implemented in real time. The results indicate that a VWSC provides a more accurate estimate of wind at hub height, ranging from 41% to 4% reduction in root mean squared error (RMSE) between predicted and actual wind speeds when using a variable wind shear coefficient at heights ranging from 33% to 100% above the highest actual wind measurement.

  • Studies on Shokyo, Kanzo, and Keihi in Kakkonto Medicine on Prostaglandin
           E2 Production in Lipopolysaccharide-Treated Human Gingival Fibroblasts

    • Abstract: We previously demonstrated that a kampo medicine, kakkonto, decreases lipopolysaccharide- (LPS-) induced prostaglandin E2 (PGE2) production by human gingival fibroblasts. In this study, we examined the herbs constituting kakkonto that exhibit this effect. Shokyo strongly and concentration dependently and kanzo and keihi moderately decreased LPS-induced PGE2 production. Shokyo did not alter cyclooxygenase-2 (COX-2) activity, cytosolic phospholipase A2 (cPLA2), annexin 1 and COX-2 expression, and LPS-induced extracellular signal-regulated kinase (ERK) phosphorylation. Kanzo inhibited COX-2 activity but increased annexin 1 and COX-2 expression and did not alter LPS-induced ERK phosphorylation. Keihi inhibited COX-2 activity and LPS-induced ERK phosphorylation but slightly increased COX-2 expression and did not alter cPLA2 and annexin 1 expression. These results suggest that the mechanism of shokyo is through the inhibition of cPLA2 activity, and that of kanzo and keihi is through the inhibition of COX-2 activity and indirect inhibition of cPLA2 activity. Therefore, it is possible that shokyo and kakkonto are clinically useful for the improvement of inflammatory responses.

  • Primary Hyperparathyroidism and Pancreatitis: A Rare Association with
           Multiple Facets

    • Abstract: Primary hyperparathyroidism (PHPT) is rarely associated with the occurrence of acute or chronic pancreatitis. Hypercalcemia plays a major role in the pathogenesis. We report five cases of pancreatitis revealing PHPT. Patients and Methods. This is a retrospective study of 4 years, including all patients admitted to intensive care unit or gastroenterology department, for an acute or chronic pancreatitis revealing primary hyperparathyroidism. Results. We included 5 patients, all female, with mean age 54 years [40–76 years]. The PHPT was in all cases revealed by acute pancreatitis (AP). This one was oedematous in four cases and severe in one case. It occurred twice in calcified chronic pancreatitis (CCP). There was hypercalcemia in all cases. The PHPT was associated with a high rate of parathyroid hormone in 4 cases. The secreting lesion was an adenoma in 5 cases. Two patients had in addition bilateral renal calcifications. The outcome was favorable in 4 patients among whom 3 have had parathyroid surgery. A death was noted by superinfection of necrosis in the case of severe AP. Conclusion. The occurrence of pancreatitis during hyperparathyroidism is rare. Normal or elevated calcemia during acute or chronic pancreatitis should always get attention.

  • Estimation of Cyclic Shift with Delayed Correlation and Matched Filtering
           in Time Domain Cyclic-SLM for PAPR Reduction

    • Abstract: Time domain cyclic-selective mapping (TDC-SLM) reduces the peak-to-average power ratio (PAPR) in OFDM systems while the amounts of cyclic shifts are required to recover the transmitted signal in a receiver. One of the critical issues of the SLM scheme is sending the side information (SI) which reduces the throughputs in wireless OFDM systems. The proposed scheme implements delayed correlation and matched filtering (DC-MF) to estimate the amounts of the cyclic shifts in the receiver. In the proposed scheme, the DC-MF is placed after the frequency domain equalization (FDE) to improve the accuracy of cyclic shift estimation. The accuracy rate of the propose scheme reaches 100% at = 5 dB and the bit error rate (BER) improves by 0.2 dB as compared with the conventional TDC-SLM. The BER performance of the proposed scheme is also better than that of the conventional TDC-SLM even though a nonlinear high power amplifier is assumed.

  • Birth Preparedness and Complication Readiness Practice and Associated
           Factors among Pregnant Women, Northwest Ethiopia

    • Abstract: Background. Little is known about birth preparedness and complication readiness (BPCR) plan in resource limited settings to decrease maternal mortality. Therefore, this study was done to assess the status of BPCR and associated factors among pregnant women in South Wollo, Northwest Ethiopia, by involving 819 pregnant women from March to April, 2014. Data were collected by using pretested interviewer administered questionnaire and analyzed using a computer program of SPSS version 20.00. Results. Pregnant women who were prepared for at least three elements of BPCR were 24.1%. Pregnant women knowing at least three key danger signs during pregnancy, delivery, and postnatal period were 23.2%, 22.6%, and 9.6%, respectively. Women having secondary education and higher were 6.20 (95% CI = [1.36, 28.120]) times more likely to be prepared than illiterates. Women having a lifetime history of stillbirth [5.80 (1.13, 29.63)], attending ANC for last child pregnancy [5.44 (2.07, 14.27)], participating in community BPCR group discussion [4.36 (1.17, 16.26)], and having their male partner involved in BPCR counseling during ANC follow-up [4.45 (1.95, 10.16)] were more likely to be prepared. Conclusions. BPCR was very low and should be strengthened through health communication by involving partner in BPCR counseling.

  • Generalized Robertson-Walker Space-Time Admitting Evolving Null Horizons
           Related to a Black Hole Event Horizon

    • Abstract: A new technique is used to study a family of time-dependent null horizons, called “Evolving Null Horizons” (ENHs), of generalized Robertson-Walker (GRW) space-time such that the metric satisfies a kinematic condition. This work is different from our early papers on the same issue where we used -splitting space-time but only some special subcases of GRW space-time have this formalism. Also, in contrast to previous work, we have proved that each member of ENHs is totally umbilical in . Finally, we show that there exists an ENH which is always a null horizon evolving into a black hole event horizon and suggest some open problems.

  • Automatic Analysis of Retinal Vascular Parameters for Detection of
           Diabetes in Indian Patients with No Retinopathy Sign

    • Abstract: This study has investigated the association between retinal vascular parameters with type II diabetes in Indian population with no observable diabetic retinopathy. It has introduced two new retinal vascular parameters: total number of branching angles (TBA) and average acute branching angles (ABA) as potential biomarkers of diabetes in an explanatory model. A total number of 180 retinal images (two (left and right) × two (ODC and MC) × 45 subjects (13 diabetics and 32 nondiabetics)) were analysed. Stepwise linear regression analysis was performed to model the association between type II diabetes with the best subset of explanatory variables (predictors), consisting of retinal vascular parameters and patients’ demographic information. value of the estimated coefficients () indicated that, at α level of 0.05, the newly introduced retinal vascular parameters, that is, TBA and ABA together with CRAE, mean tortuosity, SD of branching angle, and VB, are related to type II diabetes when there is no observable sign of retinopathy.

  • Estimating Soil Moisture Distributions across Small Farm Fields with
           ALOS/PALSAR

    • Abstract: The ALOS (advanced land observing satellite) has an active microwave sensor, PALSAR (phased array L-band synthetic aperture radar), which has a fine resolution of 6.5 m. Because of the fine resolution, PALSAR provides the possibility of estimating soil moisture distributions in small farmlands. Making such small-scale estimates has not been available with traditional satellite remote sensing techniques. In this study, the relationship between microwave backscattering coefficient () measured with PALSAR and ground-based soil moisture was determined to investigate the performance of PALSAR for estimating soil moisture distribution in a small-scale farmland. On the ground at a cabbage field in Japan in 2008, the soil moisture distribution of multiple soil layers was measured using time domain reflectometry when the ALOS flew over the field. Soil moisture in the 0–20 cm soil layer showed the largest correlation coefficient with (). The values also showed a strong correlation with the ground surface coverage ratio by cabbage plants. Our results suggested that PALSAR could estimate soil moisture distribution of the 0–20 cm soil layer across a bare field and a crop coverage ratio when crops were planted.

  • Risky Sexual Behaviors and Associated Factors among Jiga High School and
           Preparatory School Students, Amhara Region, Ethiopia

    • Abstract: Background. Young people constitute a large number of population worldwide, and majority of this population group lives in developing countries. They are at high risk of engaging in risky sexual behaviors. These risk sexual behaviors predispose youths to several sexual and reproductive health problems like STIs, HIV, unwanted pregnancy, and abortion. So, this study was conducted to assess the magnitude of risky sexual behaviors and associated factors among Jiga high school and preparatory school students, northwest Ethiopia. Methodology. Institutional based cross-sectional study design was conducted among Jiga town high school and preparatory school students. A total of 311 students were included in the study. Systematic random sampling method was used to select study participants. Data was entered using EpiData version 3.1 and it was exported to SPSS version 22 for further analysis. Descriptive analysis and bivariate and multivariate analysis were also calculated to determine factors associated with risky sexual behavior. Result. Forty-eight (16%) of respondents reported that they had sexual intercourse. From those who start sex, 44 (14.7%) were involved in risky sexual behavior which could predispose them to sexual and reproductive health problems. More than half, 27 (56.3%), of respondents first sexual intercourse was before their eighteenth birthday. The mean age and SD of fist sexual initiation were 17.2 years old and 1.35 years, respectively. Factors associated with risky sexual behavior include respondents between the ages of 20 and 23 (AOR: 5, 95%, CI: 1.59–15.98), drinking alcohol (AOR: 2.48, 95% CI: 1.13–5.41), and having poor knowledge towards HIV/AIDS (AOR: 4.53, 95%, CI: 2.06–9.94). Conclusion. A large number of in-school youths are involved in risky sexual behaviors like early sexual initiation, having multiple sexual partners, inconsistence use of condom, and having sex with high risk partner (CSWs). Age of respondents, alcohol drinking, and poor knowledge towards HIV/AIDS were factors associated with risky sexual behavior. School and community based programs in reducing substance abuse among youths and increasing their knowledge towards HIV/AIDS are important.

  • Ants Can Expect the Time of an Event on Basis of Previous Experiences

    • Abstract: Working on three ant species of the genus Myrmica, M. ruginodis, M. rubra, and M. sabuleti, we showed that foragers can expect the subsequent time at which food will be available on the basis of the previous times at which food was present. The ants acquired this expectative ability right after having experienced two time shifts of food delivery. Moreover, the ants’ learning score appeared to be a logarithmic function of time (i.e., of the number of training days). This ability to expect subsequent times at which an event will occur may be an advantageous ethological trait.

  • Minimally Invasive Treatment of Infrabony Periodontal Defects Using
           Dual-Wavelength Laser Therapy

    • Abstract: Introduction. Surgical management of infrabony defects is an invasive procedure, frequently requiring the use of adjunctive material such as grafts or biologics, which is time-consuming and associated with expense and morbidity to the patient. Lasers in periodontal regeneration have been reported in the literature, with each wavelength having potential benefits through different laser-tissue interactions. The purpose of this case series was to assess the efficacy of a new dual-wavelength protocol in the management of infrabony defects. Materials and Methods. 32 defects (one in each patient) were treated using ultrasonic debridement, followed by flapless application of Erbium, Chromium:Yttrium, Scandium, Gallium, Garnet (Er,Cr:YSGG) laser (wavelength 2780 nm), and final application of diode laser (wavelength 940 nm). Pocket depths (PD) were measured after 6 months and repeat radiographs taken after one year. Results. The mean baseline PD was 8.8 mm (range 6–15 mm) and 6 months later was 2.4 mm (range 2–4 mm), with mean PD reduction being 6.4 ± 1.7 mm (range 3–12 mm). There was a significant gain in relative linear bone height (apical extent of bone), with mean percentage bone fill of 39.7 ± 41.2% and 53% of sites showing at least 40% infill of bone. Conclusion. The results compare favourably with traditional surgery and require further validation through randomised clinical controlled trials.

  • Control of Drug Dissolution Rate from Film Dosage Forms Containing
           Valsartan

    • Abstract: Film dosage forms (FDs) containing valsartan (VST), a popular antihypertensive drug, were prepared using a casting method with sodium alginate and other polysaccharides as the film base. Drug dissolution profiles of the FDs were investigated in limited medium. The FDs were 170–200 μm thick and were easy to handle. All FDs immediately swelled and disintegrated in the medium. About 23% of the VST incorporated into the FD prepared with 1.5% sodium alginate dissolved at 5 min. The initial dissolution rate of VST increased upon the addition of chitosan to the film base; this effect was not observed in the case of chitin. On the other hand, the rate apparently decreased upon modification with alginic acid. In addition, the solubility of VST in the dissolution medium was changed by the addition of chitosan or alginic acid. FDs prepared with polysaccharides are useful for simplifying the administration of drugs to patients, and the drug dissolution rate from FDs can be controlled by modification.

  • Prevalence and Perspectives of Complementary and Alternative Medicine
           among University Students in Atlanta, Newcastle upon Tyne, and New Delhi

    • Abstract: Objective. A cross-cultural comparative study was developed that surveyed university students in Atlanta (United States), New Delhi (India), and Newcastle upon Tyne (United Kingdom) to understand the prevalence and perspectives of CAM in three urban societies with different healthcare systems. Design. Surveys were sent to students in the three aforementioned cities. Survey distribution occurred over 6 months from May to November 2015. A total of 314 surveys were received. Results. Dietary and vitamin supplements had the highest prevalence collectively (), followed by meditation, yoga, and massage. Commentary analysis showed the importance of science and evidence in justifying CAM practice. Conclusions. Matching the most prevalent practices with their designated NCCAM categories suggested that the students were attracted to biologically based, body-based, and mind-body practices as the central themes of attraction. Selected and prevalent CAM practices suggested the students’ desire to maintain physical and mental fitness. Access to healthcare may have influence on the prevalence of CAM. Indian students were more likely to view CAM as a viable alternative to conventional medicine.

  • Nursing in Ghana: A Search for Florence Nightingale in an African City

    • Abstract: Nursing in Ghana is a crucial subject that permeates almost every issue in the society especially the field of hospital care. To a large extent, the frontiers of nursing have expanded since the time of Florence Nightingale. Globally some studies have been done to study nursing icons like her. The values in nursing practice however continue to preoccupy our minds. The need to accentuate the gains made by historical figures in nursing in present times as well as the nature of interactions between practitioners and patients continues to be of paramount concern to many across the globe and Ghana in particular. This study does an analysis of existing literature on Florence Nightingale and the nature of nursing in Ghana from the colonial times. Additionally, it analyzes responses concerning the activities of nurses and their interactions with patients in Kumasi. The varied information has been thematically pieced together to make inferences that are of great interest to nursing practitioners, policy makers, administrators, and educators among others. The findings to the study suggest among other things that the challenges faced by the nursing institution in modern times are similar to those of the earlier period. The study calls for the emulation of the positive ideas of Florence Nightingale to promote the interest of patients, a core objective championed by a revered nurse.

  • Guidelines for Reporting Medical Research: A Critical Appraisal

    • Abstract: As a response to a low quality of reporting of medical research, guidelines for several different types of study design have been developed to secure accurate reporting and transparency for reviewers and readers from the scientific community. Herein, we review and discuss the six most widely accepted and used guidelines: PRISMA, CONSORT, STROBE, MOOSE, STARD, and SPIRIT. It is concluded that the implementation of these guidelines has led to only a moderate improvement in the quality of the reporting of medical research. There is still much work to be done to achieve accurate and transparent reporting of medical research findings.
