CLINICOPATHOLOGICAL STUDY OF MULTIPLE MYELOMA WITH EXPRESSION OF CD56
Authors: Bhattacharyya Jina , Devi Gabyanjali
Published: April 2021

Background: Multiple myeloma (MM) is a plasma cell neoplasm with spectrum of clinical presentation and multisystem involvement. CD56 (a
neural cell adhesion molecule, NCAM) is a membrane glycoprotein belonging to the immunoglobulin superfamily. Normal plasma cells do not
express CD56, but it is frequently expressed by malignant plasma cells in patients with MM. The present study was conducted to evaluate the
expression of CD56 in MM and its association with disease characteristics.
Methods: We analysed CD56 expression in 34 newly diagnosed MM cases using immunohistochemistry in bone marrow core biopsies processed
routinely.
Results: CD56 expression was found in 70.97% cases. The clinicopathological disease characteristics such as age, serum creatinine level, serum
β2-microglobulin level and plasmablastic morphology showed no statistically signicant difference between CD56 positive and negative groups.
Bone lesions were signicantly higher in positive cases than in negative cases.
Conclusion: CD56 expression dene a unique clinicopathological entity in MM. Expression of CD56 correlate well with lytic bone lesion and may
correlate with its pathogenesis.

Uteroplacental apoplexy or couvelaire uterus is a pathological entity which is seen alongside severe concealed placental abruption. Severe
placental vascular damage causes haemorrhage and this further causes blood to intravasate into the uterine musculature and serous coat. It is
difcult to predict or diagnose this condition and this incidental nding is only known upon direct visualisation or biopsy of the uterus, making its
reporting infrequent. This case report is regarding a 24 year old woman, G P L A previous LSCS , at 24 weeks of gestation came with bleeding per 3 1 1 1,

Evaluation of Performance of Cloud of Things (CoT) for Transferring Multimedia and Bulk-set Data
Authors: B Vivekanadam
Published: April 2021

As the number of context-aware and unique data extracting and computing has grown leaps and bounds, paving way to their application in many platforms, Internet of Things (IoT) has gained a lot of importance in recent years. Using IoT, it is possible to connect any number of objects and in any context, giving rise to a diverse range of services. Hence power management, data storage, service discovery, service management, service creation and resource management need a more sophisticated mechanism and a better infrastructure. However, a single IoT that is power-constrained will not be able to tackle all the data that is generated. Hence cloud computing plays a crucial role by integrating with the IoT in such a way that the future internet and envisioned IoT is achievable. There are a number of challenges involved of which data trimming is common challenge. Due to unnecessary communication, the data this sent to the cloud may be interrupted. Hence to prevent this, data is initially preprocessed following which it is trimmed and then transferred to the cloud. This aspect of data processing can be carried out through Fog Computing or Smart Network that serves as a smart gateway. In this paper, we have introduced a novel concept Fog computing as the smart gateway. The results have been analysed and tested with respect to bulk-data synchronizstion Delay, bulk-data upload delay, jitter, synchronization delay and upload delay.

Authors:   Candidate of Economic Sciences, Senior Researcher of the Central Economics and Mathematics Institute of RAS, Energy economic problems laboratory Moscow, Russia, FILKIN M. E.
Published: April 2021

The article is devoted to the analysis of retail gasoline prices in Moscow in the period after the start of the spread of coronavirus infection. We analyze the statistical data on changes in wholesale and retail prices for the main brands of gasoline and diesel fuel during the pandemic. Empirical data reveal the effect of the damper price regulation mechanism, which makes it possible to soften the reaction to sharp fluctuations in world oil prices. It is shown that positive and negative price shocks in the world oil market during the pandemic smoothed out at the level of wholesale prices for oil products in Russia, and practically neutralized at the level of retail prices.

This paper is focusing on an important transportation application encountered in supply chains, namely the capacitated two-stage fixed-charge transportation problem. For solving this complex optimization problem we described a novel hybrid heuristic approach obtained by combining a genetic algorithm based on a hash table coding of the individuals with a powerful local search procedure. The proposed algorithm was implemented and tested on an often used collection of benchmark instances and the computational results obtained showed that our proposed hybrid heuristic algorithm delivered competitive results compared to the state-of-the-art algorithms for solving the considered capacitated two-stage fixed-charge transportation problem.

Determination of Underground Mineable Reserve with Regard to Metal Price Uncertainty and Sustainable Development
Authors: Narrei Somaye , Ataee-pour Majid
Published: April 2021

Mineable reserve determination is one of the important parameters in economic profitability and the safety of underground mining production. The fluctuations in the metal prices will lead to a change in the cut-off grade, and as a result, the mine layout and mineable reserve will change. On the other hand, changing the underground mine layouts will also change the economic, social and environmental impacts (sustainable development parameters). Therefore, ignoring metal price uncertainty lead to a non-optimal design. The aim of this paper is the determination of underground mineable reserve regarding metal price uncertainty and sustainable development. Metal price uncertainty is simulated with Monte Carlo technique and the most important sustainable development indicators are entered in the cut-off grade formula. In this way, four types of cut-off grades were defined. Based on these cut-offs four types of mine layouts are obtained. Basic, simulated, green and sustainable mine layout. Basic Mine layout is that obtained by normal design, simulated mine layout considers just metal price uncertainty, green mine layout considers metal price uncertainty and environmental criteria and sustainable mine layout considers metal price uncertainty and environmental and social criteria. Results from the use of this methodology in a hypothetical gold mine show that the mineable reserve in sustainable mine layout is 17 percent greater than the basic mine layout. Regarding the result, with this methodology in addition to consideration of metal price uncertainty and sustainable development criteria, the more mineable reserve will be achieved. For future research, in addition to using other price simulation methods; it is suggested that other indicators of sustainable development be included in determining the underground mine layout.

Published: April 2021

The COVID-19 pandemic spread rapidly throughout the world, but some populations were more affected than others. For example, compared to other groups, a higher morbidity and mortality was documented in African Americans and individuals of Mediterranean descent. These populations are marked by both increased prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency, and lower utilization of angiotensin receptor blockers/angiotensin converting enzyme inhibitors in the treatment of hypertension. In this brief report, we suggest that G6PD status should be assessed in all COVID-19 positive individuals belonging to the two ethnic groups. If detected, N-acetylcysteine should be utilized to lower the oxidative burden and “sartans” should be prescribed as first-line therapy in hypertensive individuals.

Free Vibration Analysis of Thick Isotropic Plate by Using 5th Order Shear Deformation Theory
Authors: Gajbhiye Param D. , Bhaiya Vishisht , Ghugal Yuwaraj M.
Published: April 2021

In the present study, a 5th order shear deformation theory (5th OSDT) is presented for free vibration analysis of simply supported thick isotropic plates. Governing equations and boundary conditions are evaluated using the concept of virtual work. Numerical results for free vibration analysis include the effects of side to thickness and plate aspect ratios for simply supported thick isotropic plates. Non-dimensional bending mode frequencies, non-dimensional thickness shear mode frequencies and non-dimensional thickness stretch mode frequencies are obtained. Closed form analytical solutions for simply supported isotropic thick plates subjected to single sinusoidal distributed loads are obtained for comparison purpose. The problems considered in this study are solved using MATLAB software. Non-dimensional bending frequencies and non-dimensional thickness shear mode frequencies obtained through the 5th OSDT match well with the exact analytical and exponential shear deformation theory (ESDT) results. Further, the non-dimensional thickness stretch mode frequencies are found to be imaginary.
CREATIVE INTEGRATION OF DESIGN THINKING AND STRATEGIC THINKING IN A DESIGN EDUCATION FRAMEWORK
Authors: Park Woonghee , Lee Hyun-Kyung
Published: April 2021

With rapid globalization, designers are increasingly required to use creative integration of strategic thinking and design thinking to deal with complexity and uncertainty in an era of constant transformation. This study reviews the current status of design education to address the key question of how strategic thinking and design thinking can be enhanced creatively in undergraduate design students’ education in South Korea. Furthermore, it investigates the key drivers for and barriers to the enhancement of strategic thinking and design thinking; seeks insights from successful design education programs; and gathers perspectives about strategic thinking and design thinking from design students, educators, and strategists. By using qualitative (in-depth interviews) and quantitative (a questionnaire) research methods, the study offers significant insights: (i) design undergraduates’ short-sighted mind-set should be reshaped, (ii) additional practical, multicultural, and interdisciplinary applications of strategic thinking are needed to bridge the gap between theoretical and practical classes, and (iii) consistent stimulation is required to internalize strategic thinking and design thinking.
Lizards of a different stripe: phylogenetics of the Pedioplanis undata species complex (Squamata, Lacertidae), with the description of two new species
Authors: Childers Jackie L. , Kirchhof Sebastian , Bauer Aaron M.
Published: April 2021

The lacertid genus Pedioplanis is a moderately speciose group of small-bodied, cryptically-colored lizards found in arid habitats throughout southern Africa. Previous phylogenetic work on Pedioplanis has determined its placement within the broader context of the Lacertidae, but interspecific relations within the genus remain unsettled, particularly within the P. undata species complex, a group largely endemic to Namibia. We greatly expanded taxon sampling for members of the P. undata complex and other Pedioplanis, and generated molecular sequence data from 1,937 bp of mtDNA (ND2 and cytb) and 2,015 bp of nDNA (KIF24, PRLR, RAG-1) which were combined with sequences from GenBank resulting in a final dataset of 455 individuals. Both maximum likelihood and Bayesian analyses recover similar phylogenetic results and reveal the polyphyly of P. undata and P. inornata as presently construed. We confirm that P. husabensis is sister to the group comprising the P. undata complex plus the Angolan sister species P. huntleyi + P. haackei and demonstrate that P. benguelensis lies outside of this clade in its entirety. The complex itself comprises six species including P. undata, P. inornata, P. rubens, P. gaerdesi and two previously undescribed entities. Based on divergence date estimates, the P. undata species complex began diversifying in the late Miocene (5.3 ± 1.6 MYA) with the most recent cladogenetic events dating to the Pliocene (2.6 ± 1.0 MYA), making this assemblage relatively young compared to the genus Pedioplanis as a whole, the origin of which dates back to the mid-Miocene (13.5 ± 1.8 MYA). Using an integrative approach, we here describe Pedioplanis branchisp. nov. and Pedioplanis mayerisp. nov. representing northern populations previously assigned to P. inornata and P. undata, respectively. These entities were first flagged as possible new species by Berger-Dell’mour and Mayer over thirty years ago but were never formally described. The new species are supported chiefly by differences in coloration and by unique amino acid substitutions. We provide comprehensive maps depicting historical records based on museum specimens plus new records from this study for all members of the P. undata complex and P. husabensis. We suggest that climatic oscillations of the Upper Miocene and Pliocene-Pleistocene era in concert with the formation of biogeographic barriers have led to population isolation, gene flow restrictions and ultimately cladogenesis in the P. undata complex.

Patricia A. Martin, PhD, RN; Janet Dugan, MS, RN; Margaret Freundl, MSN, RN; Susan E. Miller, MS, RN; Rita Phillips, MSN, RN, FNR C; and Loretta Sharritts, MS, RN

ABSTRACT

This study measured the knowledge of and attitudes toward the nursing process held by nurses who provide direct patient care. The Dayton Attitude Scale Toward Care Planning (DASC) was returned by 1,096 nurses practicing in nine hospitals. Overall, participants were knowledgeable of the nursing process and held a relatively positive attitude toward the nursing process and nursing diagnosis. Higher nursing degrees were associated with more positive attitudes. The most common barrier to the use of the nursing process was insufficient time. The study found that less than 30% of the subjects liked the way care planning was done. These findings suggest that improving care planning systems would further promote consistency in the process.

The Communication Training Needs of Registered Nurses
Authors: Johnson John R
Published: April 2021

ABSTRACT

The purpose of this study was to determine registered nurses' (RN) perceived levels of communication effectiveness and need for communication training. Results of the survey indicate that RNs view themselves as fairly effective in using most job-related communication skills except for performance appraisal interviewing, public speaking, and persuasion. The majority of RNs had received training in most communication skills, the exceptions being persuasion and employment interviewing. The two most prominent sources for this training were college and on-the-job training. The results also indicate that RNs believe a variety of communication skills, including presentational speaking, listening, persuasive speaking, group problem solving, leadership, and technical report writing, are important to their job performance. The majority of RNs thought they needed additional training in these skills and were willing to receive such training. Their preferences for receiving the instruction were in-house or industry-based training seminars and profession-sponsored continuing education programs.

Published: April 2021

ABSTRACT

The decision of the Brigham and Women's Hospital (BWH) to expand its capacity to care for acute cardiac surgical and neurosurgical patients resulted in the need for an education and training program for a large group of nursing staff. In such situations, where an existing service is being expanded or a new service initiated, nursing education departments must quickly devise simple and cost-effective mechanisms to promote the competency of nursing staff. Nurse educators, staff nurses, nurse managers, and clinical nurse specialists all play a role in planning and implementing the relevant education and evaluation program. BWH chose to recruit temporary special projects staff nurses to address these increased educational needs.
Documenting Patient Education A Literature Review
Authors: Casey Frances S
Published: April 2021

ABSTRACT

Lack of time is cited as the most common reason why staff nurses neglect to document patient education. Consumer rights, standards of practice, and other laws regulating nursing practice require nurses to teach patients. Administration and staff development can enhance nurses' efforts to document more effectively. Forms and flowsheets detailing content and learner outcomes and tracking patients' progress can affect the quality of documentation. Nurses are encouraged to continue developing new forms and flowsheets and to share their products with others.

Perinatal Staff Nurse Medical Device Use and Education
Authors: McConnell Edwina A
Published: April 2021

ABSTRACT

Background: How and what RNs working in the perinatal area initially learned about the medical devices they use and the sequelae of device use both for patients and staff were explored.

Method: Eighty-five perinatal staff nurses working at a 500-bed tertiary care hospital in a medium-size midwestern American city were surveyed using a mailed questionnaire comprised of 26 open-ended and closed-ended questions pertaining to device education, consequences of device use, demographic characteristics, and employment situation.

Results: Most participants (n = 48, 62.3%) initially learned about the most frequently used device by reading the user/instruction manual. At least 90% (n = 77) of participants indicated they initially had learned how to operate the device, its purpose, function, and patient factors indicating use. Inadequate device knowledge was related to nurse stress, and being unsure how to use the device and fear of harming the patient were the two reasons most frequently identified as causing the stress. Six percent (n = 5) of staff nurses had used a device that caused patient harm.

Conclusion: What RNs initially learn about medical devices may be related to how they learn, and the continuing increase in nurse use of medical devices has implications for all aspects of professional nursing: curriculum, teaching clinical nursing, continuing education and staff development, and research.

ABSTRACT

Background: Staff development educators in a Department of Education & Development were seeking a creative activity to reinforce the qualities of effective teams.

Method: Staff development educators developed an experiential activity that provides an opportunity to observe team behaviors by introducing several glitches into a goal-oriented team project. Later, observed team behaviors were explored with the group.

Results: The activity allowed participants to practice collaboration, communication, and problem-solving skills while functioning as a team.

Conclusion: This activity, which is easily adaptable to any audience, creatively integrates the principles of adult learning to provide participants with an opportunity to discuss and practice behaviors necessary for teamwork in the current health care settings.
Educating Nursing Staff in a Long-Term Care Facility on Cerumen Impactions and Cerumenolytic Administration

Published: April 2021

The current article examines the importance of educating nursing staff in a long-term care facility (LTCF) on cerumen impactions and the proper administration of cerumenolytics. An educational session on cerumen impactions and cerumenolytic administration was provided to nursing staff with pre-, post-, and follow-up tests. Findings included an increase in confidence levels of the nursing learning objectives post-education, as well as an overall improvement in knowledge retention. According to the nurses surveyed, they had never been educated on either topic. It is estimated that up to 65% of residents aged >65 years living in LTCFs are affected by cerumen impactions and the many symptoms associated with them, including hearing loss. Therefore, education on these topics for nursing staff who care for this high-risk population would be beneficial. [

CHONDROMALACIA PATELLA: A NONOPERATIVE TREATMENT PROGRAM
Authors: Wissinger H Andrew
Published: April 2021

ABSTRACT: One hundred consecutively selected patients with chondromalacia patella were examined arthroscopically. The severity of the disease process was graded on the basis of the arthroscopic examination. A well-controlled nonoperative treatment program was instituted, and the end results were then tabulated when a minimum two-year follow-up had been achieved.

A review of the literature revealed that others have graded chondromalacia.1"4 There have been previous reports of well-controlled nonoperative programs for chondromalacia patella utilizing a classification system based upon axial x-ray.5*6 A therapeutic approach to chondromalacia patella has been report ed, but no results of the efficacy of the system are available.7

The need for a study combining an adequate sample, pretreatment grading of the severity of the disease, a uniform treatment program, and statistically significant results of the program became apparent.
INCARCERATION SCAPULA: A NEW CAUSE OF SCAPULAR WINGING
Authors: Chmell Samuel , Light Terry R
Published: April 2021

ABSTRACT: Scapular winging may occur with forceful marked internal rotation and hyperabduction of the upper extremity. Closed treatment has been demonstrated to be effective in the case of a 29-year-old man injured by a twisting force on the shoulder girdle. Although scapulothoracic dislocation and long thoracic nerve paralysis are far more common etiologies for scapular winging, extensive damage to periscapular muscles and ligaments can also cause this problem.
CAST-BRACING OF FEMORAL FRACTURES: EXPERIENCE AT EMORY UNIVERSITY HOSPITALS
Authors: St Pierre Rick K , Holmes Hamilton E , Fleming Lamar L
Published: April 2021

ABSTRACT: At Emory University Hospitals from 1975 to 1979, 110 fractures of the femoral shaft were treated following a femoral fracture protocol with a single component cast-brace and early ambulation. In an effort to reduce the hospitalization and disability time in patients with mid-third and distal-third femoral fractures, a technique of modified Dehne bracing was used in which immediate ambulation was instituted after casting. Prior to initiation of this protocol, these fractures were routinely treated with six to eight weeks of balanced traction, followed by four to six months of cast fixation and a subsequent period of rehabilitation. Complications of the technique occurred in 9% of the patients, with shortening of 2.3 cm in 5%, refractures in 3% and malunion in 1%.

This series of patients demonstrates the technical feasibility of a single component cast-brace and early ambulation for fractures of the femoral shaft, which is a great advance in the closed treatment of femoral fractures. Our results show that early cast-bracing using a modified Dehne technique is a viable method of treating fractures of the femoral shaft, with the technique being most effective when applied in the early stages- days one through 28. Indexing terms: cast-bracing, femoral fractures.

Total Hip Replacement in Patients Under Thirty-five Years of Age
Authors: Kunec James R
Published: April 2021

ABSTRACT: Twelve patients under the age of 35, each with a collagen vascular disorder, had 16 total hip replacements performed for hip arthropathy. Nine of the patients had systemic lupus erythematous and osteonecrosis of the femoral head. Followup at the average of 5.2 years revealed that 41% of the patients had developed complications relating to the prosthetic device. Loosening of the components was a cause of failure in 19% of the hips. Four revision arthroplasties have been performed and another one is anticipated. Three of these revisions were performed before the patients' thirtieth birthday.
Olecranon Fractures Treated With AO Screw and Tension Bands
Authors: Johnson Roger Paul , Roetker Alan , Schwab Jeffrey P
Published: April 2021

ABSTRACT: Twenty-eight patients averaging 36.4 years of age underwent open reduction and internal fixation of olecranon fractures. The AO cancellous screw was used alone in 16 and with tension banding in 12. Banding was used when the bone was soft or severely comminuted. The fractures were clinically healed at an average of nine weeks and roentgenographic healing with obliteration of the fracture line occurred at 13 weeks. Sixty-seven percent acquired full motion by the ninth postoperative week. All but two patients regained full supination and pronation. No patient lost greater than 30° of extension and only two lost greater than 30° of flexion. There were few operative difficulties or postoperative complications.

We found the AO cancellous screw alone and in severely comminuted cases in combination with tension band wiring to be an excellent fixation device for olecranon fractures. It allows for early range of motion in young patients with excellent healing prospects by 16 weeks.

Published: April 2021

ABSTRACT: A consecutive series of 71 Bateman hemiarthroplasties were performed in a single hospital over a 20-month period. Forty-four hips or 62% were available for review with an average follow up of 22 months. Of the 44 cases, the Bateman Universal Proximal Femur, original design was used in 40 acute, displaced femora! neck fractures, two failed Austin Moore prostheses, and two cases of femoral head osteonecrosis unassociated with fracture. The mean Harris hip score was 84.7%. Of the patients 93.2% had minimal or no pain. The range of motion was excellent and the dislocation rate was 1.8%. Morbidity was not increased compared to more conventional unipolar implant procedures. The Bateman Universal Proximal Femur (UPF) is felt to offer improved surgical results compared to Austin Moore and Thompson prostheses, and this may be due to the low friction inner bearing motion that occurs with this bipolar implant.

ABSTRACT: The strength of five commercially available synthetic orthopedic casting products are discussed. Using three testing designs, significant differences could be consistently determined. These testing methods provide a means of comparing the various casting products on the market.

The authors point out that this study was a comparison of ultimate strength only, and did not compare the other characteristics of the products. It also was noted that all these synthetic casting materials were stronger than plaster-of-Paris casting material.
NEUROLOGIC DEFICITS ASSOCIATED WITH SACRAL WING FRACTURES
Authors: Rai Sajith K , Far Rointan F , Ghovanlou Bijan
Published: April 2021

ABSTRACT

Twelve of 96 patients with pelvic fractures suffered neurologic deficits. Four secondary to acetabular fractures were excluded from the study. Of the remaining eight, five were found by CT scan to be secondary to fractures of the sacral wing extending through the sacral foramina. On the basis of this study, it is believed that the neurologic injuries were due to sacral root injuries rather than lumbosacral plexus injuries. This concept potentially could lead to surgical approaches for decompression of sacral root trauma.
