The Rise of Digital Health and Potential Implications for Pharmacy Practice
Authors: Clark Mickayla , Clark Thomas , Bhatti Afeefa , Aungst Timothy
Published: November 2020

The rise of technology in healthcare has led to dramatic changes in approaches to patient care by healthcare professionals. The realm of digital health has created new opportunities for pharmacists to engage patients in clinical practice. Pharmacies and industry are increasingly integrating these innovations into their businesses and practice. This article highlights areas of digital health for pharmacists to be aware of, in particular regarding areas of medication adherence and disease management.

Technology plays a massive role in our individual lives; it has morphed the human experience in ways that were simply unimaginable 50 years ago. We use technology in nearly every facet of our lives. From detecting an appropriate intensity with which to brush our teeth to counting calories lost through the course of a day, technology has made a major impact on individual health. The integration of technology into our everyday lives has changed the way we communicate, how we capture and share our lives with others, how we seek answers, and how we experience life overall. Given this change in the way people operate, it is important that pharmacists adapt to these trends and incorporate technology into daily practice. The incorporation of mobile devices and technology into healthcare has been coined as mobile health (mHealth), which falls under the broader spectrum of digital health.1 –4 Digital health focuses on the integration of mobile tools (e.g., smartphones), wearable devices, and telehealth to help personalize the treatment of patients through the widespread adoption of wireless technology. The idea of involving pharmacists in mHealth has been a topic of recent interest, due in large part to the potential ramifications for the profession.4 Today, patients are using the Internet to research their health questions and help guide their personal health choices, and some of the information they find can be misleading and unreliable. It is of the utmost importance that healthcare professionals ensure there are credible sources for patients to research their questions. As pharmacists, we can research and recommend tools to patients to help solve problems related to drug information, medication adherence, and access, which includes the recent rise of novel technological devices. All of our patients will have different comfort levels with technology; despite this spectrum, there is a place for everyone to feel comfortable using digital health tools. However, there are recent technological advances coming to the field, which are already providing a benefit to patients, ranging from mobile applications to wearable technologies to ingestible medications that notify providers of patient medication adherence. We seek to help pharmacists understand the different areas of digital health, which may have substantial influence on the realm of pharmacy practice in the years to come by addressing current and upcoming digital health developments.
THE GUIDELINE FOR CUSTOMISING INCREMENTAL HOUSING BASED ON TWO CHILEAN CASE STUDIES
Authors: Marinovic Goran Ivo
Published: November 2020

Incremental housing, supported by governmental funding, denotes a solution for low-income households where they can gradually customise their dwelling. The Chilean government officials and architects proposed phases of construction which fell short of addressing the households’ capabilities and motivation to finalise their units. Hereof, this article looks at two incremental housing projects: Lo Espejo condominium (2007) and Las Higueras (2006) in the Santiago Metropolitan Region, Chile, to inquire capacities of government officials and architects’ comprehensive assistance to families’ housebuilding. The hypothesis holds that the greater responsibility of government officials and architects engaged with incremental housing will enhance motivation of low-income families to customise their house by self-building practice. Arguing for the importance of the self-building the author proposed the guideline for customising houses that comprises four phases: introducing the incremental construction design idea, discussing with families the possibilities for completing houses, connecting households’ construction plans with their financial resources, and presenting the customisation design template. This guideline structure is founded on extensive nine months fieldwork in the Santiago Metropolitan Region, carried out in close collaboration with low-income households from two neighbourhoods, the Ministry of Housing and Urbanism of Chile, the Architectural Office Elemental, and “Gubbins Arquitectos.”

COI and ND1 as DNA barcodes to identify Taenia hydatigena (Cestoda: Taeniidae) from canine small intestine on Hainan Island in China
Authors: Lu Yajun , Yang Siqi , Liu Jingwen , Lu Xixi , Zhao Qiuyu
Published: November 2020

DNA barcoding based on universal gene markers is a fast, accurate, and innovative approach for the molecular discrimination of species. Some species are particularly difficult to discriminate using a traditional morphological identification method because of severely damaged morphological features. In this study, cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit 1 (ND1) were used as barcoding markers to distinguish Taenia hydatigena in dogs on the tropical island of Hainan. Therefore, geographic differentiation based on the COI and ND1 sequences amongst the specimens and other geographic isolates in GenBank was determined by calculating the genetic distances according to the Kimura 2-parameter (K2P) model and constructing a phylogenetic tree using the neighbour-joining (NJ) method. Barcoding gap, base composition, and base saturation were tested to assess the effectiveness of the barcoding marker COI and ND1 genes for specimen identification. In addition, we analysed the barcoding gap and saturation and performed molecular evolutionary analysis of the intraspecies and interspecies diversity of Taenia.
A report of a new species and new record of Cadlina (Nudibranchia, Cadlinidae) from South Korea
Authors: Do Thinh Dinh , Jung Dae-Wui , Kil Hyun-Jong , Kim Chang-Bae
Published: November 2020

Of the four species in the genus Cadlina present in the northwestern Pacific region, C. japonica has been the only species recorded from South Korea. For the purpose of investigating Cadlina in Korean waters, specimens were collected from the Korean East Sea (Sea of Japan) by scuba diving. The radula and morphology of these specimens were examined by stereoscopic and scanning electron microscopy. Based on morphology, three species were identified in Korean waters, including the new species, Cadlina koreanasp. nov., C. umiushi (first record in South Korea), and C. japonica. Cadlina koreanasp. nov. somewhat resembles C. umiushi but differs in both its morphology as well as the structure of its radula. The background color of Cadlina koreanasp. nov. is translucent white, tubercles on the dorsum are opaque white and the yellow marginal band is absent. The radular formula of Cadlina koreanasp. nov. is 57 × 23.1.23 with a rectangular rachidian tooth. In addition, mitochondrial cytochrome c subunit 1 (COI), 16S ribosomal RNA (16S rRNA), and nuclear 28S ribosomal RNA (28S rRNA) gene sequences were generated and used for analysis of Automatic Barcode Gap Discovery (ABGD) and reconstruction of the phylogenetic tree. Morphological distinction and genetic analyses confirm that three Cadlina species are present in Korean waters of which Cadlina koreana is a new species.

The micropolydesmoid millipede family Haplodesmidae is here recorded from Cambodia for the first time through the discovery of the first, new species of the genus Eutrichodesmus Silvestri, 1910: E. cambodiensissp. nov. This new species is described from two limestone habitats in Kampot Province, based on abundant material. It is easily distinguished from all related congeners by the following combination of characters: body greyish-brown; limbus roundly lobulate; solenomere partially divided from acropodite by a digitiform lobe, but without hairpad. Brief remarks on the previously-proposed “pecularis-group” are provided and a second group, the “demangei-group”, is established and discussed on the basis of morphological evidence, updating the number of recognised species groups of Eutrichodesmus to two. Detailed morphological illustrations, photographs and a distribution map, as well as remarks on its habitat and mating behaviour of the new species are presented. Furthermore, the current distributions of all 55 presently-known species of Eutrichodesmus are provided and a key to all 23 species that occur in mainland Southeast Asia is given.
Effectiveness of the CRISP Method on the Primary Cardiac Arrhythmia Interpretation Accuracy of Nurses
Authors: Çıkrıkçı Isık Gülşah , Şafak Tuba , Tandoğan Meral , Çevik Yunsur
Published: November 2020

Background:

Accurate electrocardiogram (ECG) interpretation is key to quickly providing attention to patients, and the first health staff who evaluate ECGs are nurses.

Method:

This was a prospective study with a pre–posttest design. The study test included 15 ECGs related to primary cardiac arrhythmias. After pretest nurses were instructed on arrhythmia interpretation using the Cardiac Rhythm Identification for Simple People (CRISP) method, posttests were completed.

Results:

There was a significant difference between the pretest scores of nurses who had postgraduate education on ECG interpretation and who did not (p= .002). Median test score increased from 3 (interquartile range [IQR] = 2–5) to 7 (IQR= 5–9) (p< .001). Participants mostly missed questions about heart blocks and were most successful with questions about fatal arrhythmias after education.

Conclusion:

The CRISP method is an effective, simple, and easy method for accurate ECG interpretation by nurses. The posttest scores of the participants, especially accurate interpretation of fatal arrhythmias, increased significantly after training.[J Contin Educ Nurs. 2020;51(12):574–580.]

Published: November 2020

Physical activity is an important part of clinical assessment. However, objective measurement can be expensive and burdensome. The current study validated a single activity question for use in clinical assessment. Ninety-seven older women (mean age = 73.7 years,
SE
= 0.7) completed an activity questionnaire and measurement of anthropometrics, body composition, and strength. Activity level was reported as
not active
,
somewhat active
,
active
, and
very active
. Activity level was significantly related to hours of light, moderate, and vigorous activity; body mass index (BMI); waist circumference; percent fat and lean mass; and strength (
p
< 0.05). When activity levels were collapsed into two groups (not active + somewhat active, and active + very active), women in the high activity group (
n
= 48) were significantly (
p
< 0.05) more active, had healthier BMI and waist circumference values, less fat and more lean mass, and were stronger than women in the low activity group (
n
= 49). A single activity question is valid for use in clinical assessment. [

Long-Term Care Nurses and Their Experiences With Patients' and Families' End-of-Life Preferences: A Focus Group Study
Authors: O'Conner-Von Susan , Bennett Frank
Published: November 2020

Long-term care (LTC) nurses are a critical nexus for patient communication and vital to advance care planning due to their professional role and breadth of patient relationships. The current study's aim was to explore the communication strategies Midwestern LTC nurses use to clarify patients' end-of-life (EOL) care preferences. Two focus groups used a phenomenological framework to elucidate the experiences of 14 RNs. Data analysis revealed two themes grounded in time: (a) nurses use time to assess patients' EOL situation and assist patients to discern care options; and (b) nurses educate patients about EOL care, adjust care plans, and develop trusting relationships. Two themes were grounded in clinical experience: (a) nurses become persistent advocates and educators to initiate and sustain EOL communication; and (b) nurses learn consistency in communication, including awareness of patients' nonverbal communication. Nurses shared that EOL communication is never “done”; time frames to assess, educate, and clarify are continuous. [

Published: November 2020

BACKGROUND AND OBJECTIVE:

To report the long-term anatomic and visual outcomes of patients with Stickler syndrome undergoing retinal detachment (RD) surgery.

PATIENTS AND METHODS:

Retrospective, interventional, consecutive case series of patients with Stickler syndrome undergoing RD repair from 1999 to 2017 at the Long Island Vitreoretinal Consultants, New York. Retinal attachment status and visual acuity (VA) at 1-year and last follow-up were assessed.

RESULTS:

Successful reattachment was achieved in 28 of 29 eyes (97%) with an average of 2.3 surgeries (including silicone oil removal surgeries). Redetachment after the first surgery occurred in 13 eyes (45%). Mean Snellen VA at initial presentation, 1-year follow-up, and last follow-up were 20/289, 20/118 (
P
= .012), and 20/103 (
P
= .022), respectively.

CONCLUSIONS:

Anatomic success can be achieved in most eyes. However, redetachments are common, and multiple surgeries are often required. Reasonable visual recovery is possible in many eyes.

OCT Assistance in Identifying Retinal Breaks in Symptomatic Posterior Vitreous Detachments
Authors: Ansari Waseem H. , Blackorby Barton L. , Shah Gaurav K. , Blinder Kevin J. , Dang Sabin
Published: November 2020

BACKGROUND AND OBJECTIVE:

Posterior vitreous detachment (PVD) is a separation of the posterior hyaloid from the retina that manifests as photopsias and floaters. Optical coherence tomography (OCT) has demonstrated posterior vitreous opacities (PVOs) that may correlate with Shaffer's sign, which may correlate with retinal breaks.

PATIENTS AND METHODS:

Patients with symptomatic PVDs were retrospectively reviewed at a single institution by a single provider. Masked qualitative review of SD-OCTs by a single reviewer determined presence of PVOs.

RESULTS:

Among 78 patients, PVOs were found in 32 of the patients (41%), and 19 (59%) had retinal breaks. In those without PVOs, six (13%) had a break. Sensitivity and specificity were 76.0% and 75.5%, respectively. Removing patients with vitreous hemorrhages, sensitivity, and specificity of PVOs was 82.4% and 86.4%, respectively.

CONCLUSION:

In symptomatic PVDs, PVOs on OCT correlated with the presence of a retinal break, especially in the absence of a vitreous hemorrhage.

Incentives on E-Commerce App Downloads in Medium Apps: A Case Study on the Effects of Coupons and Bonus Points
Authors: Wohllebe Atilla , Stoyke Thomas , Podruzsik Szilárd
Published: November 2020

With the spread of mobile smartphone apps among consumers, they have also become increasingly important for e-commerce companies in recent years to attract customers. A central challenge in the use of smartphone apps by companies is the acquisition and activation of new app users. This case study examines how incentives like coupons and bonus points to download an e-commerce app via other smartphone apps, so-called "medium apps", have an effect. After a review of existing literature on similar topics, hypotheses regarding the probability of installation and actual app usage are developed and tested in an experiment. The hypotheses can be confirmed to a large extent, but especially coupons for the advertised online shop that publishes the e-commerce app do not show the expected effect. Further research questions are identified and practical recommendations for app marketing are derived.

Authors: Wohllebe Atilla , Ross Florian , Podruzsik Szilárd
Published: November 2020

Mobile apps have become massively more important in the retail sector in recent years. A central challenge for retailers is the acquisition of new users for their mobile apps. A potentially interesting target group for this can be a company's existing, satisfied customer base, whereby customer satisfaction is often measured by the willingness to recommend the app or the Net Promoter Score. This paper investigates the influence of the willingness to recommend a retailer by consumers on their willingness to install a mobile app from this retailer. The influence of usage habits is also examined. The analysis of a survey of 105 consumers on a total of five retailers can confirm the hypotheses regarding the willingness to recommend a retailer and the Net Promoter Score (NPS) in particular: With the willingness to recommend, the willingness to install a retailer's app also increases.

Data Mining and Business Intelligence
Authors: Azevedo Ana
Published: November 2020

From the middle of this second decade of the 21st century, analytics has become commonly associated with the topics business intelligence and data mining. Data mining (DM) is being applied with success in business intelligence (BI) environments and several examples of applications can be found. BI and DM have different roots and, as a consequence, have significantly different characteristics. DM came up from scientific environments; thus, it is not business oriented. DM tools still demand heavy work in order to obtain the intended results. On the contrary, BI is rooted in industry and business. As a result, BI tools are user-friendly. This chapter reflects on these differences from a historical perspective. Starting with a separated historical perspective of each one, analytics, BI, and DM, the author then discusses how they converged when DM is used and integrated in BI environments with success.

Authors: Belaala Abir , Terrissa Labib Sadek , Zerhouni Noureddine , Devalland Christine
Published: November 2020

Spitzoid lesions may be largely categorized into Spitz Nevus, Atypical Spitz Tumors, and Spitz Melanomas. Classifying a lesion precisely as Atypical Spitz Tumors or AST is challenging and often requires the integration of clinical, histological, and immunohistochemical features to differentiate AST from regular Spitz Nevus and malignant Spitz Melanomas. Specifically, this paper aims to test several artificial intelligence techniques so as to build a computer-aided diagnosis system. A proposed three-phase approach is being implemented. In Phase 1, collected data are preprocessed with an effective SMOTE-based method being implemented to treat the imbalance data problem. Then, a feature selection mechanism using genetic algorithm (GA) is applied in Phase 2. Finally, in Phase 3, a 10-fold cross-validation method is used to compare the performance of seven machine-learning algorithms for classification. Results obtained with SMOTE-Multilayer Perceptron with GA-based 14 features show the highest classification accuracy, specificity (0.98), and a sensitivity of 0.99.

Efficient Learning From Two-Class Categorical Imbalanced Healthcare Data
Authors: Mathews Lincy , Seetha Hari
Published: November 2020

When data classes are differently represented in one v. other data segment to be mined, it generates the imbalanced two-class data challenge. Many health-related datasets comprising categorical data are faced with the class imbalance challenge. This paper aims to address the limitations of imbalanced two-class categorical data and presents a re-sampling solution known as ‘Syn_Gen_Min' (SGM) to improve the class imbalance ratio. SGM involves finding the greedy neighbors for a given minority sample. To the best of one's knowledge, the accepted approach for a classifier is to find the numeric equivalence for categorical attributes, resulting in the loss of information. The novelty of this contribution is that the categorical attributes are kept in their raw form. Five distinct categorical similarity measures are employed and tested against six real-world datasets derived within the healthcare sector. The application of these similarity methods leads to the generation of different synthetic samples, which has significantly improved the performance measures of the classifier. This work further proves that there is no generic similarity measure that fits all datasets.

Authors: Laksono Agung Dwi , Wulandari Ratna Dwi , Matahari Ratu
Published: November 2020

Background

Modern contraceptive methods are considered more reliable for preventing and spacing pregnancy than traditional methods in sexual activity. The study aimed to analyze the association between recent sexual activity and the use of modern contraceptive methods among married/cohabiting women in Indonesia.

Design

The samples used were married/cohabiting women aged 15-49 years old. The sample size was 34,467 women. The variables analyzed included modern contraceptive use, recent sexual activity, age groups, marital status, education level, and wealth status. Analysis using multinomial logistic regression.

Results

It was found that women who were sexually not active last 4 weeks had the likely to use modern contraceptive non-LARC (long-acting reversible contraceptives) 0.416 times compared to women who were sexually active last 4 weeks. Women who were sexually active last 4 weeks were more likely to use modern contraceptive LARC 0.535 times than women who were sexually active last 4 weeks.

This study reports the impact of the HiFive program, a 6-week handwashing campaign that targets social and emotional motivators to improve student handwashing in primary schools in the Philippines. We designed a clustered randomized trial to evaluate the impact of HiFive on student handwashing behavior, motivation, and access. Of the sample of 196 primary schools located in two districts, half were randomly assigned to receive the program in the 2017–2018 school year. Survey and observation data were collected 3 months after the conclusion of the campaign. In control schools, only 2.5% of students were observed washing their hands with soap and water, our primary outcome and 14.8% were observed washing their hands with at least water. HiFive led to a 3.7 percentage point (p.p.) increase (P < 0.01) in the rate of handwashing with soap and water and a 5.6 p.p. increase (P = 0.03) in handwashing with at least water after toilet use. HiFive also led to a 10.8 p.p. (P < 0.01) increase in the number of handwashing facilities stocked with soap. The program had limited impact on the motivators targeted by the program, suggesting that the small improvements in handwashing may have been driven by increases in the availability of soap. More research is needed to understand how interventions can effectively trigger social motivators to improve handwashing behavior among schoolchildren, and whether the effectiveness of these programs can be augmented with “nudge”-based interventions from the behavioral sciences.

The unprecedented coronavirus pandemic is hitting the whole world, including the United Arab Emirates. Public awareness and adherence to the recommendations play a major role in managing a crisis of this magnitude which is largely affected by knowledge, attitudes, and practices (KAP). Hence, the aim of this study was to assess COVID-19–related KAP of the University of Sharjah (UOS) students and compare between health-related (HR) and non-HR (NHR) majors. A cross-sectional study was conducted in May 2020 in which 1,012 (481 health-related and 531 NHR) students participated via an online KAP questionnaire. The students’ sociodemographic characteristics and sources of information were also recorded, and data were analyzed. Students were aged 20–25 years, with an overall knowledge score of 72.4%, and the main source of their information was the Internet and social media (85.2%). Those in HR majors had a higher knowledge score (76%) than those in NHR students (69%). Regarding attitudes, both HR and NHR students demonstrated comparable and positive attitudes to curb the spread. With respect to practices, more NHR students used masks (92.3%), almost all the time than HR students (88.4%). HR students (99.4%) avoided crowded places and practiced social distancing more than NHR students (99.4% versus 97.4% and 97.7% versus 93.2%, respectively). In conclusion, UOS students demonstrated adequate knowledge, and possessed good attitudes and low-risk practices toward prevention of COVID-19. It is recommended that universities including UOS continue to use digital university communication platforms to regularly disseminate vital information in such emergencies.

In industrialized countries, Mycobacterium avium complex and other nontuberculous mycobacteria (NTM) are major causes of opportunistic infection–related deaths in HIV patients. However, in resource-limited regions, data on NTM are scarce, and tuberculosis (TB) was often assumed to be the cause of death in HIV patients with a positive acid-fast smear. We searched MEDLINE and Embase databases for studies on autopsied HIV patients in sub-Saharan Africa published between January 1997 and April 2020. We included studies that reported histopathological or microbiological evidences for diagnosis of TB and NTM infection. We excluded articles without mycobacterial evidence from culture or molecular testing, such as those that used verbal autopsy, death certificates, or national registry data (systematic review registration number: CRD42019129836 at PROSPERO). We included six eligible studies that reported 391 autopsies in sub-Saharan African HIV patients. The prevalence of NTM and TB at autopsy ranged from 1.3% to 27.3% and 11.8% to 48.7%, respectively. The weighted prevalence ratio of NTM versus TB was 0.16 indicating that for every seven HIV patients died with mycobacterial infections, there was one died with NTM infection. Of the 13 NTM infections, six were caused by M. avium complex. Mycobacterium avium complex and other NTM infections are important differential diagnoses of TB at the time of death among HIV patients in sub-Saharan Africa. Our findings highlight the need to systematically survey the prevalence of NTM infections among HIV patients seeking medical care in resource-limited regions.
A Path-Server Traffic Scheduling Algorithm for Wireless Network Load based on SDN
Authors: Zhou Jie
Published: November 2020

At present, the research on flow scheduling optimization around SDN has become the focus of international attention. Based on the current traffic control algorithm, especially the shortcomings of traffic scheduling optimization, Path-Server Traffic Scheduling (PSTS) algorithm is proposed in this paper to solve problems. Based on the real-time monitoring of network on Ryu controller, network topology, network load and server load information were obtained to choose the optimal routing scheme, thus achieving the goal of improving the overall network performance. Through the interaction between the components, the work flow of the Ryu controller is designed, and the channel quality information among users is maintained by the link state management module. When the small base station receives the data packet sent by the SDN exchange price, it will temporarily store it in the data cache module. Then, according to the amount of cached data and the channel quality of each user, the optimal time slot of the wireless network resource allocation scheme is comprehensively determined, and the data packet is sent to the corresponding client. In the view of proposed design, the Mininet simulation platform is used to simulate the SDN network in this paper. Based on the simulation platform, the performance of the algorithm is analyzed and compared. Besides, bandwidth utilization, average transmission delay, system utility and terminal usage change, interrupt rate and terminal usage change of different algorithms in SDN wireless network are analyzed and compared through data. All experiments have proved that the research content proposed in this paper has an obvious effect on network load control, which shows network performance.
Discontinuous Legendre Wavelet Galerkin Method for Optimal Control of Time Delayed Systems

Published: November 2020

Time-delay systems arise in many important applications in science and engineering and optimal control of delay differential equations are of theoretical and practical importance. This paper presents discontinuous Legendre wavelet Galerkin (DLWG) approach for solving optimal control problem of time-delayed systems. This new method demonstrates that operational matrices of derivative, delay and product are lower dimensions and sparse because of calculation only on each subinterval. The advantages are implemented to solve algebraic equations transformed from the time-delayed systems with less storage space and execution time. Finally, an experiment is included to illustrate the effectiveness and applicability of the proposed method

Objective: We aimed to compare emergency and elective cesarean patients in our hospital in terms of epidemiological features and maternal morbidity.

Material and Methods: We randomly retrospectively reviewed the records of 302 caesarean cases. Demographic features and indications for emergency (group 1) and elective caesarean section (C/S) (group 2) were recorded. The groups were compared in terms of indications and intraoperative and postoperative morbidity.

Results: It was found that the mean hematocrit decrease in group 1 was not different from group 2 (5.70 ± 1.16 and 5.62 ± 0.67). When the groups are examined according to cesarean indications; In group 1 patients, fetal distress, cephalopelvic disproportion (CPD), non-progress of labor, abruptio placentae were significantly higher compared to group 2, whereas in group 2 patients the previous 1 C / S and previous 2 C / S indications were significantly higher. Intraoperative hemorrhage and bladder injury were more common in group 1 patients compared to group 2 patients. When the groups are examined according to postoperative maternal complications; In group 1 patients, transfusion, prolonged bladder catheterization, admission to intensive care unite (ICU), was significantly higher compared to group 2.

Conclusion: It was found that many intraoperative and postoperative complications were more common in the emergency C/S group. it was also detected that all cases with bladder injuries had previous cesarean sections. Therefore, the presence of experienced personnel in these cases may be important for reducing morbidity due to the increased risk of complications.
