Genomics and Nursing Practice: Advancing the Nursing Profession
Authors: Badzek Laurie , Turner Martha , Jenkins Jean
Published: March 2022

The remarkable advances in genetics and genomics over the last three decades have necessitated initiatives on the part of all healthcare disciplines to assist providers in applying this new knowledge in practice. Nursing has responded by planning and implementing a number of projects that address the challenging issues created by genetic and genomic advances. This article presents an overview of the considerable progress made in sequencing the human genome, progress that has provided the opportunity for the remarkable advances we are seeing in healthcare today. It also describes how various professional healthcare groups and associations are working together to enhance nurses’ understanding of this genomic revolution, thus paving the way for nurses to develop core competencies, and enabling them to incorporate genomic advances into their daily nursing care. The American Nurses Association Code of Ethics for Nurses is presented as a framework for responding to these rapidly occurring changes. Two case studies illustrate how nurses are applying the emerging science and technology in genetics and genomics to advance the nursing profession and provide competent nursing care to patients faced with genetic and genomic healthcare concerns.
A Collaboration Challenge: Interdisciplinary Clinical Research by Faculty in Non-Research-Focused Colleges and Universities
Authors: Broscious Sharon , Darby Michele , Loftin Karin
Published: March 2022

Conducting research in the clinical arena is a challenging endeavor, both because the researchers have limited control over the environment and because of the high level of collaboration needed between the researchers and the clinical staff in the research setting. It becomes even more complex when the research involves an interdisciplinary research team whose members’ primary responsibility is their teaching and teaching-related activities. Yet involvement of both faculty and students in research is important. This article describes some of the challenges related to the collaboration needed by an interdisciplinary research team consisting of faculty members, students, and health care agency staff. Being aware of these challenges in planning interdisciplinary clinical research, and making plans early on to meet these challenges, can minimize the untoward effects of these challenges on a study’s outcomes. These challenges include finding an appropriate clinical site, gaining entrée to the site, establishing staff-researcher relationships, recruiting participants, involving students in the study, finding the time needed for the study, collecting the data, and obtaining adequate funding. The authors conclude that the funding challenge has the most significant impact on the ability of a faculty research team to collaborate on a research study in a clinical setting. Suggestions for meeting these challenges and enhancing the collaboration between the research team and clinical site are included.

Transitioning From Nursing Practice to a Teaching Role
Authors: Penn Barbara , Wilson Laurie , Rosseter Robert
Published: March 2022

The national dialogue about the expanding nurse faculty shortage has piqued the interest of many nurses in practice and motivated them to pursue a teaching role. Thought eager to share their clinical expertise as nurse educators, many of them have questions about what is required to transition from the clinical practice setting to the academic environment, even on a part-time basis. This article provides practical advice on how to find teaching opportunities in higher education and make the role transition successfully. The authors address types of faculty appointments, educational qualifications needed for teaching, considerations in taking a faculty position, beginning a faculty position and learning about the academic work environment, and faculty development opportunities. They conclude by paying special attention to the essential skills needed to become a nurse educator and flourish in a teaching role.
Addressing Nurse-to-Nurse Bullying to Promote Nurse Retention
Authors: Rocker Carol
Published: March 2022

Nurse-to-nurse bullying in the workforce is contributing to the current nursing shortage. The literature reveals both victims and witnesses of bullying suffer silently and are often confused as to what to do when presented with bullying behavior. This confusion frequently contributes to nurses leaving their chosen profession. Canadian lawmakers are now beginning to address workplace bulling behaviors. The purpose of this paper is to raise awareness of the challenges associated with workplace bullying among nurses by defining and describing the incidence and origin of workplace bullying; reporting the nature of and consequences of workplace bullying for both victims and witnesses; presenting the Canadian legal response, strategies to support victims, and approaches preventing workplace bullying; and considering the nurse manager’s role in addressing workplace bullying.

À l’instar de la Sécurité sociale, ce projet est fondé sur la cotisation des citoyennes et des citoyens en vue de la reconnaissance des droits à une alimentation de qualité. L’entretien réalisé avec Romain Henry pour la Confédération paysanne souligne la portée sociale et politique d’un projet intimement lié à la transition agroécologique de l’agriculture.
Dynamics of patchy vegetation patterns in the two-dimensional generalized Klausmeier model
Authors: Wong Tony , Ward Michael J.
Published: March 2022

We study the dynamical and steady-state behavior of self-organized spatially localized patches or "spots" of vegetation for the Klausmeier reaction-diffusion (RD) system of spatial ecology that models the interaction between surface water and vegetation biomass on a 2-D spatial landscape with a spatially uniform terrain slope gradient. In this context, we develop and implement a hybrid asymptotic-numerical theory to analyze the existence, linear stability, and slow dynamics of multi-spot quasi-equilibrium spot patterns for the Klausmeier model in the singularly perturbed limit where the biomass diffusivity is much smaller than that of the water resource. From the resulting differential-algebraic (DAE) system of ODEs for the spot locations, one primary focus is to analyze how the constant slope gradient influences the steady-state spot configuration. Our second primary focus is to examine bifurcations in quasi-equilibrium multi-spot patterns that are triggered by a slowly varying time-dependent rainfall rate. Many full numerical simulations of the Klausmeier RD system are performed both to illustrate the effect of the terrain slope and rainfall rate on localized spot patterns, as well as to validate the predictions from our hybrid asymptotic-numerical theory.

Published: March 2022

This paper proposes the D-optimal design for the additive mixture model with two-response, which is linear model with no interaction terms. The optimality was validated by using the general equivalence theorem, and the corresponding weights are found under which additive model satisfies D-optimality. In addition, relevant statistics and graphics are given to illustrate our results.
A Dimensionality Reduction Approach in Helicopter Hover Performance Flight Testing
Authors: Arush Ilan , Pavel Marilena D. , Mulder Max
Published: March 2022

The power required to hover a helicopter is fundamental to any new or modified performance flight-testing effort. The conventional method of relating two nondimensional variables (coefficients of power and weight) is overly simplified and neglects compressibility effects in the power
required to hover under a wide range of gross weights and atmospheric conditions. An alternative flight-test method for assessing hover performance while addressing this deficiency of the conventional method is proposed. The method uses an original list of 15 corrected variables derived from
fundamental dimensional analysis, which is further reduced by means of dimensionality reduction to include only the most essential and effective predictors. The method is demonstrated using data of a Bell Jet-Ranger and shows that at the 95% confidence level; the averaged prediction error
is only 0.9 hp (0.3% of the maximum continuous power). Using the same data, the conventional method yields a much larger averaged prediction error of 1.7 hp.

Authors: Juraga Denis , Rukavina Tomislav , Bilajac Lovorka , Glavić Mihaela Marinović , Roviš Darko , Raat Hein , Vasiljev Vanja
Published: March 2022

Background

To compare the effectiveness between conventional (face-to-face) and online public health approaches focused on mental health, self-efficacy of health management and quality of life of older adults.

Design and methods

Participants will be 65+ residents of the city of Rijeka and the wider urban area and will be divided into three groups. The first group consists of participants who will be included in the conventional (face-to-face) form of public health intervention, the second group consists of participants who will be involved in online public health intervention and the third group consists of participants from the control group. A total of 450 participants will participate in a pretest-posttest non-equivalent groups design research, with 150 participants per group. A series of questionnaires will be administered to evaluate effect of the interventions on mental health, self-efficacy of health management and quality of life. Results of this research will provide insight into the effectiveness of the electronic way of implementing chronic disease self-management interventions compared to conventional (face-to-face) which can be useful to policy makers and public authorities in the organization and implementation of health policies. Expected impact of the study for public health: This research will contribute to the definition, implementation and adaptation of future public health interventions related to mental health, selfefficacy of health management and quality of life in the context of various epidemiological situations such as the current one caused by the COVID-19 pandemic.
The Epidemiology of Ankle Sprains in US High School Sports, 2011–2012 to 2018–2019 Academic Years
Authors: Kerr Zachary Yukio , Nedimyer Aliza K. , Simon Janet E. , Kossman Melissa K. , Corbett R. O. , Chandran Avinash
Published: March 2022

Context

Continued monitoring of ankle sprain rates and distributions is needed to assess temporal patterns and gauge how changes in incidence may be associated with prevention efforts.

Objective

To describe the epidemiology of ankle sprains in 16 US high school sports during the 2011–2012 to 2018–2019 school years.

Design

Descriptive epidemiology study.

Setting

Online injury surveillance from high school sports.

Patients or Other Participants

High school athletes who participated in practices and competitions during the 2011–2012 to 2018–2019 school years.

Main Outcome Measure(s)

A convenience sample of high school athletic trainers provided injury and athlete-exposure (AE) data to the National High School Sports-Related Injury Surveillance Study (data provided by High School Reporting Information Online [HS RIO]). Ankle sprain rates per 10 000 AEs with 95% CIs and distributions were calculated. Yearly rates were examined overall and by event type, injury mechanism, and recurrence.

Results

Overall, 9320 ankle sprains were reported (overall rate = 2.95/10 000 AEs; 95% CI = 2.89, 3.01). The highest sport-specific rates were reported in girls' basketball (5.32/10 000 AEs), boys' basketball (5.13/10 000 AEs), girls' soccer (4.96/10 000 AEs), and boys' football (4.55/10 000 AEs). Most ankle sprains occurred during competition (54.3%) and were due to contact with another person (39.5%) or noncontact (35.0%). Also, 14.5% of injuries were recurrent. Across the included academic years, ankle sprain rates generally increased. Compared with the 2011–2012 academic year, rates in the 2018–2019 academic year overall were 22% higher; noncontact-related and recurrent ankle sprain rates also generally increased by 91% and 29%, respectively.

Conclusions

Time trends suggested that ankle sprain rates have increased across the past decade, particularly among those with noncontact-related mechanisms, contrasting with previous research that indicated decreases in incidence. These findings may pinpoint specific etiologic factors that should direct prevention efforts, including considering both person-contact and noncontact mechanisms by mitigating illegal contact through rule changes and enforcement, as well as bracing and proprioceptive and balance-training programs.
Phloretin-induced suppression of oxidative and nitrosative stress attenuates doxorubicin-induced cardiotoxicity in rats
Authors: Wagh Shivani S. , Patil Kalpesh R. , Mahajan Umesh B. , Bagal Pradnya D. , Wadkar Avinash R. , Bommanhalli Basavraj , Patil Prabhakar R. , Goyal Sameer N. , Ojha Shreesh , Patil Chandragouda R.
Published: March 2022

Objective:

To compare the cardioprotective efficacy of equimolar doses (50 mM/kg, p.o.) of phloretin and genistein against doxorubicin-induced cardiotoxicity in rats.

Methods:

Cardiotoxicity was induced in rats by intraperitoneal injection of 6 mg/kg doxorubicin on alternative days till the cumulative dose reached 30 mg/kg. This study included four treatment groups of rats (n=6): the control group (0.5% carboxymethyl cellulose solution-treated), the doxorubicin- treated group (0.5% carboxymethyl cellulose solution along with doxorubicin), the genistein-treated group (50 mM/kg/day; p.o. along with doxorubicin) and phloretin-treated group (50 mM/kg/day; p.o. along with doxorubicin). On the 10th day of dosing, rats were anesthetized for recording ECG, mean arterial pressure, and left ventricular function. Oxidative stress, nitric oxide levels, and inflammatory cytokines were estimated in the cardiac tissue. Cardiac function parameters (creatine kinase MB, lactate dehydrogenase, aspartate aminotransferase, and alanine transaminase) were estimated in the serum samples.

Results:

Phloretin treatment inhibited doxorubicin-induced oxidative stress and also reduced nitric oxide levels in cardiac tissues of rats. Phloretin administration attenuated doxorubicin- induced alterations in hemodynamic parameters (heart rate, mean arterial blood pressure, and left ventricular function) and suppressed the expression of pro-inflammatory cytokines. The cardiac injury markers like creatine kinase MB, lactate dehydrogenase, aspartate aminotransferase, and alanine transaminase were reduced by both genistein and phloretin. All these effects of phloretin were more prominent than genistein.

Conclusions:

Phloretin offers cardioprotection that is comparable to genistein, a clinically validated cardioprotectant against doxorubicin-induced cardiotoxicity. Further studies are needed to confirm and establish the therapeutic utility of phloretin as a chemopreventive adjuvant to doxorubicin chemotherapy.
Predictors of Early Neurological Deterioration Following Intravenous Thrombolysis
Authors: Nair Srikumar B. , Somarajan Deepthi , Pillai Rammohan K. , Balachandran Keerthi , Sathian Sona
Published: March 2022

Background:

Prevention of early neurological deterioration (END) is becoming an important therapeutic target in acute ischemic stroke management. The aim of the study is to ascertain the causes and predictors of early neurological deterioration following thrombolysis and determine the predictive value of IScore.

Methods:

In this single center prospective study, we analyzed clinical, imaging and outcome data in 168 patients thrombolyzed intravenously ≤4.5 hours from onset of stroke. Early neurological deterioration was defined as worsening ≥2 points in the NIHSS score at 24 hours.

Results:

END occurred in 34 patients (20%) and caused significantly worse short term outcome. Ischemic END (ENDi) (n = 23) was twice as common as symptomatic hemorrhage (ENDh) (n = 11). Ischemia progression (n = 15) was the most common cause. Early malignant edema was another major cause. On multivariate analysis, significant predictors (p <.05) were proximal artery occlusion [all END (p <.001), ENDi and ENDh], previous ischemic insults (all END) and raised diastolic blood pressure (ENDh). ENDi was more common in those with carotid artery occlusion, large vessel disease and previous ischemic insults. ENDh was more common in those with raised diastolic blood pressure and NIHSS-ASPECTS mismatch. For patients with NIHSS <14, IScore >105 and for NIHSS ≥14, IScore >175 was associated with higher risk of END.

Conclusion:

END occurs in one fifth of patients after intravenous thrombolysis; ENDi outnumbers ENDh. Proximal artery occlusion is a major predictor for END. Potentially modifiable risk factors include admission hyperglycemia and elevated blood pressures. Distinct factors characterize ENDh and ENDi and can guide prevention and management strategies. IScore identifies patients at risk for END.
Correlation between foveal microvasculature and inner retinal layer thickness in type 2 diabetes
Authors: Al-Nashar Haitham Y. , Al-Bialy Hany A.
Published: March 2022

Aim

The aim of this study was to evaluate the correlation between foveal microvasculature and inner retinal layer (IRL) thinning in patients with type 2 diabetes using optical coherence tomography angiography (OCTA).

Patients and methods

This is a prospective comparative study that included 100 eyes of 100 subjects: 50 eyes of diabetic patients with type 2 diabetes having mild to moderate nonproliferative diabetic retinopathy (NPDR) and 50 eyes of normal subjects. Foveal avascular zone (FAZ) area and vessel density of parafoveal and perifoveal areas were calculated using OCTA. The IRL thickness was measured using optical coherence tomography (OCT). The correlation between the IRL thickness and both FAZ area and macular vessel density was measured.

Results

The mean FAZ area was significantly larger in the NPDR group (0.69±0.01 mm2) than in the normal eyes group (0.45±0.02 mm2), (P=0.01). The mean parafoveal and perifoveal vessel density in the superficial capillary layer were significantly decreased in eyes with NPDR (46.7±6.5% and 43.8±7.1%, respectively) than in normal eyes (69.5±4.2% and 66.2±4.3%, respectively) (P=0.001). The mean parafoveal and perifoveal vessel density in the deep capillary layer had significantly lower values in eyes with NPDR (51.3±2.3% and 49.5±4.2%, respectively) than in normal eyes (70.1±5.4% and 68.3±3.73%, respectively), (P=0.001). The mean IRL thickness was significantly less in the NPDR eyes (54.7±6.8 μm) than in normal eyes (79.3±6.9 μm), (P=0.001). A statistically significant correlation was found between the IRL thickness and both FAZ area and macular vessel density in eyes with NPDR (P<0.001).

Conclusion

OCTA revealed that foveal microcirculatory alterations (FAZ area and macular vessel density) in diabetic eyes were related to the IRL thickness.
Primary open-angle glaucoma
Authors: Alhagaa Ahmed A. , Habib Rehab M.
Published: March 2022

Aim

The aim of this study was to show if primary open-angle glaucoma (POAG) is associated with structural neurodegenerative changes along the visual pathway.

Patients and methods

The patients included in the study were divided into two groups: group 1 (200 patients having POAG) and group 2 (200 patients having no POAG as a control group). Brain MRI was done to evaluate the structural changes in the visual pathway.

Results

MRI brain showed that patients in group 1 have significantly lower optic nerve cross-sectional area (14±2.3 mm2) compared with group 2 (35±3.1 mm2) (P=0.012), and significantly lower lateral geniculate nucleus volume (58.4±4.7 mm3 in group 1 compared with 89.2±5.9 mm3 in group 2, P=0.009).

Conclusion

The pathology in POAG extended beyond the globe to involve the optic nerve cross-sectional area, and the lateral geniculate nucleus volume was significantly lower in patients with POAG. Such changes can be precisely detected with MRI. So, MRI can be considered as a tool for diagnosis and follow-up of patients with POAG.

Authors: Eissa Iman M. , El Husseiny Mostafa A.
Published: March 2022

Purpose

The aim of this study was to assess the long-term results of a sample of myopic Egyptian patients implanted with Artisan phakic intraocular lenses (PIOL).

Patients and methods

This is a retrospective longitudinal study that used data from 52 eyes of 28 patients implanted with anterior chamber iris-fixated Artisan PIOL. The postoperative assessment included refractive status, uncorrected visual acuity and best-corrected visual acuity, endothelial cell count, and the occurrence of complications for up to 15 years postoperatively.

Results

Higher postoperative uncorrected visual acuity (mean=0.519±0.195) and best-corrected visual acuity (mean=0.706±0.199), with improved spherical equivalent (from −12.06±2.004 to −0.74±0.9 D) and decreased endothelial cell count were all found to show statistically significant differences (P=0.007, 0.000, 0.000, and 0.007, respectively) when compared with the preoperative values. Males had a tendency for higher endothelial cell loss. The preoperative anterior chamber depth was correlated negatively with the endothelial cell loss percentage (P=0.019). An average yearly loss of 2.58% of endothelial cells was recorded following surgery. Few complications were recorded including cataract, glaucoma, and corneal decompensation.

Conclusion

Long-term results of Artisan PIOL implantation in Egypt showed a statistically significant visual improvement and good refractive correction with few complications but with significant endothelial cell loss.
Retinal nerve fiber layer thickness evaluation in iron deficiency anemia patients using optical coherence tomography
Authors: El-Gamal Shaza S.A. , Zaky Adel G. , El-Sawy Moataz F.
Published: March 2022

Background

Anemia is a widespread public health problem. Iron deficiency is the most common cause of anemia. Hemoglobin (Hb) concentration was supposed to affect the retinal nerve fiber layer thickness (RNFLT).

Objective

The aim of this study was to evaluate the influence of iron deficiency anemia (IDA) on the peripapillary RNFLT using optical coherence tomography (OCT).

Patients and methods

A total of 30 patients with IDA with Hb less than 12 g/dl were enrolled in the study. Optic disk and RNFL parameters obtained by Topcon OCT in these patients were compared with those of age-matched and sex-matched nonanemic 30 individuals. The anemia group was also divided according to the Hb concentration into three groups: mild, moderate, and severe.

Results

The average age of the IDA cases and the controls was 23.38±9.06 years (range=15–30 years), and 25.37±7.64 years (range=15–30 years), respectively (P=0.09). The average right eye RNFLT in IDA patients was 98.20±10.98 µm compared with 106.30±14.05 µm in the control group (P=0.001), while in the left eye, it was 98.87±12.24 µm in the IDA group, and 105.30±6.59 µm in the control group (P=0.015). The average nasal and inferior RNFLT of the IDA group were thinner than the control group in the right eye (P=0.003 and 0.045, respectively) and in the left eye (P=0.016 and 0.038, respectively). There was a positive association between average RNFLT and Hb concentration in the right eye (r=0.554) and in the left eye (r=0.561), which was statistically significant (P=0.001). In addition, there was a positive correlation between nasal and inferior RNFLT and Hb concentration in the right eye (P=0.002 and 0.001, respectively) and in the left eye (P=0.001 and 0.002, respectively). The degree of thinning was related to the severity of anemia as the RNFL thinning was significantly more in severe anemia cases than in mild and moderate ones.

Conclusions

The peripapillary RNFLT measured by OCT was significantly thinner in the IDA patients in the average, inferior, and nasal quadrants, with more thinning in the severe than in mild and moderate groups. This finding may have a significant effect, as these pseudoglaucomatous changes could be misdiagnosed as glaucoma or other neuro-ophthalmological disorders.

Authors: Gupta Anushree , Singh Amit S.
Published: March 2022

Parinaud syndrome, also known as dorsal midbrain syndrome, is classically described by the triad of impaired upward gaze, convergence-retraction nystagmus, and pupillary hyporeflexia. Astasia refers to the inability to stand upright unassisted without significant motor or sensory impairment. Stroke is the most common cause of Parinaud syndrome and thalamic astasia in the older age group. We report a case of a 41-year-old male patient who presented with a sudden onset of binocular diplopia and inability to stand or walk unassisted. Neuroimaging revealed a lesion in the right lower thalamus and upper midbrain. Conservative management was done and his symptoms improved.
A clinical study of ocular findings among patients with COVID-19 at a tertiary care center in Western Maharashtra, India
Authors: Gaikwad Rahul , Thikeker Mahesh , Kalantri Rama
Published: March 2022

Background

More studies are required on the ocular manifestations of coronavirus disease 2019 (COVID-19) to help guide ophthalmologists to carefully screen these patients for early diagnosis, so that prompt management can be done to prevent further damage.

Aim

The aim of this study was to evaluate the ocular findings among patients with COVID-19 at a tertiary care center.

Patients and methods

A hospital record-based retrospective study was carried out on 1036 patients diagnosed with COVID-19 at a tertiary care center in Western Maharashtra, India. Visual acuity was measured at bedside by the finger-counting method or by using the Snellen's chart, if required. Anterior-segment eye examination was done on torchlight and binocular corneal loops, and slit-lamp biomicroscopy, as required. Extraocular movements were recorded in all nine gazes. Indirect ophthalmoscopy was done under full mydriasis.

Results

The age of the patients ranged from 4 to 98 years with a mean of 45.6±16.24 years. The majority (22.5%) of the patients belonged to the age group of 30–39 years. Males (61.8%) were more than females (38.2%). The ocular findings included congestion (16.8%), continuous conjunctival congestion (5.3%), vasculitic retinal-vein occlusion (8.7%), combined central retinal artery and vein occlusion (1.4%), central retinal-artery occlusion (0.8%), convergence insufficiency (8.4%), and lateral rectus paresis (3.5%). Sex was not associated with abnormal ocular findings (P>0.05). On the other hand, advanced age was a significant risk factor for ocular manifestations of COVID-19 (P<0.05). Only the abnormal ocular findings of the anterior segment were found to be associated with longer duration of hospital stay.

Conclusions

Elderly people were more likely to develop ocular manifestations of COVID-19 compared with their younger counterparts, irrespective of gender. A significant proportion of infected people developed ocular manifestations of COVID-19.
Refractory congenital chylous ascites
Authors: Ojha Sunita , Bharadia Lalit , Chaturvedi Anupam
Published: March 2022

Chylous ascites (CA) is a form of ascites having leakage of lipid-rich lymph into the peritoneal cavity, due to damage or obstruction in the lymphatic system. Aetiology of CA could be congenital or acquired. Primary lymphatic hypoplasia is seen commonly in children and presents with lymphoedema, chylothorax or CA. CA is initially treated conservatively with the aim to provide gut rest and decrease intestinal secretions. Surgical treatment is recommended if 1–2 months of conservative approach fails. The success of the operation depends on identifying the site of leakage of the lymphatic duct. Surgical options are ligation of leaking lymphatics, peritoneo-venous shunt, laparotomy and fibrin glue. Laparoscopy has been used for diagnosis but not for glue and mesh application in congenital CA where the lymphatic leak is unidentified. We present here the first experience of laparoscopic fibrin glue and mesh application in congenital CA with successful outcomes.

Published: March 2022

Giant lumbar hernia, with loss of domain, is a complex scenario to treat. Abdominal compartment syndrome is a dreaded post-operative complication. This can gravely impair the patient's respiratory function and also cause insufficient perfusion of the viscera. Pre-operative progressive pneumoperitoneum can facilitate bowel repositioning and can reduce impairment of the post-surgery lung function, essential for a favourable post-operative outcome. Here, we describe the treatment of a case of giant lumbar incisional hernia by the creation of progressive pneumoperitoneum and hybrid repair of incisional hernia with left posterior component separation and placement of giant prosthetic reinforcement of the defect.

Published: March 2022

Moringa oleifera Lam. (Shigru) (Moringaceae family) is a traditional medicine used for control of diabetes, obesity, asthma, and cardiac, liver, gastrointestinal, infective, and brain disorders, such as depression and Alzheimer's disease. In Ayurvedic literature, Shigru is among few drugs having Balya (nourishing) as well as Medohara (antiobesity) property. This review focuses on valid connections between the properties documented in ancient literature and current pharmacological knowledge of Moringa, including pharmacological actions, phytochemistry, botanical description, and how Moringa can tackle malnutrition in India, especially Chhattisgarh. All information about M. oleifera was obtained from electronic scientific databases such as PubMed, Web of Science, Scopus, ScienceDirect, Elsevier, Google Scholar, Traditional Knowledge Digital Library, and Indian Traditional Books (Ancient Ayurveda literatures, The Wealth of India, and The Ayurvedic Formulary of India), postgraduate/doctoral thesis, and googling the keyword M. oleifera. M. oleifera have anti-oxidant, antimicrobial, anti-diabetic, anti-obesity, anti-inflammatory, cardioprotective, hepatoprotective, neuroprotective, gastroprotective, wound-healing properties and it can potentially tackle malnutrition. This review describes the key information related to botanical description of M. oleifera, phytochemistry, pharmacological actions, clinical studies, toxicological studies, better utilization as food therapeutics, and ethnobotanical and evidence-based comparative review of M. oleifera. M. oleifera can effectively tackle malnutrition in India, especially Chhattisgarh. The authors emphasize the need for future in-depth ethnopharmacological lead-based research and clinical studies to expand M. oleifera pharmacological activities, clinical efficacy, and safety.

Independent Component Analysis (ICA) is a method for searching the linear transformation that minimizes the statistical dependence between its components. Most popular ICA methods use kurtosis as a metric of independence (non-Gaussianity) to maximize, such as FastICA and JADE. However, their assumption of fourth-order moment (kurtosis) may not always be satisfied in practice. One of the possible solution is to use third-order moment (skewness) instead of kurtosis, which was applied in ICA_SG and EcoICA. In this paper we present a competitive approach to ICA based on the Split Generalized Gaussian distribution (SGGD), which is well adapted to heavy-tailed as well as asymmetric data. Consequently, we obtain a method which works better than the classical approaches, in both cases: heavy tails and non-symmetric data

Việc xác định đúng giá trị cũng như xác định đầy đủ các thành phần của tải trọng và tác động là một yếu tố rất quan trọng trong tính toán thiết kế công trình. Yếu tố này quyết định đến các yêu cầu về Kinh tế - Kỹ thuật của một dự án và được thể hiện qua tổng mức đầu tư xây lắp và các ràng buộc về độ bền; ổn định; biến dạng; tuổi thọ của công trình. Thực tiễn đã chứng minh nhiều vấn đề tiềm ẩn và phát sinh liên quan đến công trình do đánh giá chưa xác đáng về tải trọng và tác động gây ra. Bên cạnh đó, tải trọng và tác động không mang yếu tố cố hữu về giá trị cũng như cách thức tác động, mà nó phụ thuộc vào sự thay đổi của điều kiện tự nhiên và điều kiện kinh tế xã hội. Ngày nay, chúng ta đang đứng trước những thay đổi lớn lao của tải trọng không kém dị thường về cách thức tác động do điều kiện kinh tế xã hội gây ra, mà còn chịu sự thay đổi rất lớn từ các điều kiện tự nhiên. Đồng thời, đất nước chúng ta đang trong tiến trình hội nhập Quốc tế hóa – Toàn cầu hóa, sự tiếp cận một cách đồng bộ hệ thống Tiêu chuẩn kỹ thuật là điều tất yếu. Bài viết này, tôi đề cập đến một số điểm khác biệt trong tính toán tải trọng và tác động giữa TCVN 2737:2020 so với TCVN 2737:1995 áp dụng cho Công trình xây dựng Dân dụng và Công nghiệp.

Ngày nay, việc đào tạo nguồn nhân lực đáp ứng yêu cầu của doanh nghiệp và người sử dụng lao động là mục tiêu hàng đầu của các cơ sở đào tạo. Theo đó, “sản phẩm” của các cơ sở đào tạo là những sinh viên năng động, tích cực, chuyên sâu về kiến thức và giỏi các kỹ năng mềm. Để tạo ra được các “sản phẩm sinh viên” chất lượng, các cơ sở đào tạo phải liên tục cải tiến phương pháp giảng dạy, lựa chọn các phương pháp giảng dạy tích cực, phù hợp với yêu cầu của đổi mới giáo dục. Việc cải tiến phương pháp giảng dạy đòi hỏi giảng viên phải là người đóng vai trò chủ đạo, tiên phong trong việc thay đổi chất lượng giáo dục; bản thân mỗi giảng viên luôn phải chuyển hóa và thay đổi chính mình về cả lượng và chất. Trong bài này, chúng tôi trình bày một số phương pháp giảng dạy tích cực bao gồm các nội dung sau: việc triển khai các phương pháp giảng dạy tích cực, những ưu - khuyết điểm của một số phương pháp dạy học tích cực; kết quả của việc áp dụng phương pháp giảng dạy tích cực trong Trường Đại học Công nghiệp Thành phố Hồ Chí Minh; hướng tích hợp vào chương trình đào tạo để nâng cao chất lượng dạy - học phù hợp với sự phát triển và nhu cầu của xã hội về nguồn nhân lực chất lượng cao và đào tạo ứng với thực tế.

Nghiên cứu được thực hiện nhằm tìm hiểu đánh giá của sinh viên về các kết quả họ đạt được từ trải nghiệm học tập tại trường Đại học Công nghiệp TP. HCM (IUH) cũng như mức độ hài lòng của sinh viên đối với trải nghiệm này. Khảo sát bằng bảng hỏi được sử dụng để thu thập dữ liệu. Thống kê mô tả được sử dụng để phân tích dữ liệu. Dữ liệu thu được từ trả lời của 497 sinh viên đang theo học tại Trường cho thấy: (i) sinh viên cho rằng trải nghiệm học tập tại trường có đóng góp nhiều vào sự phát triển nhân cách, nhưng chỉ đóng góp ở mức trung bình đối với sự tích lũy kiến thức, phát triển các kỹ năng học tập và sự chuẩn bị cho nghề nghiệp tương lai của họ; (ii) mức độ hài lòng của sinh viên đối với trải nghiệm học tập tại trường chưa cao. Về mặt lý luận, nghiên cứu đã bổ sung những khía cạnh còn ít được đề cập trong các nghiên cứu ở Việt Nam về kết quả đào tạo của giáo dục đại học ví dụ như sự đóng góp của các trường đại học đối với sự phát triển nhân cách của sinh viên và sự chuẩn bị nghề nghiệp cho sinh viên. Về mặt thực tiễn, nghiên cứu đã chỉ ra một số khía cạnh Nhà trường cần cải thiện để nâng cao chất lượng đào tạo của mình bao gồm việc chú trọng phát triển cho sinh viên tư duy phản biện, các kỹ năng viết, phân tích số liệu thống kê, giải quyết vấn đề cũng như  việc tạo ra một môi trường học tập thân thiện hơn cho sinh viên.
Seasonal Prediction for May Rainfall over Southern China Based on the NCEP CFSv2

In this study, we assess the prediction for May rainfall over southern China (SC) by using the NCEP CFSv2 outputs. Results show that the CFSv2 is able to depict the climatology of May rainfall and associated circulations. However, the model has a poor skill in predicting interannual variation due to its poor performance in capturing related anomalous circulations. In observation, the above-normal SC rainfall is associated with two anomalous anticyclones over the western tropical Pacific and northeastern China, respectively, with a low-pressure convergence in between. In the CFSv2, however, the anomalous circulations exhibit the patterns in response to the El Niño-Southern Oscillation (ENSO), demonstrating that the model overestimates the relationship between May SC rainfall and the ENSO. Because of the onset of the South China Sea monsoon, the atmospheric circulation in May over SC is more complex, so the prediction for May SC rainfall is more challenging. In this study, we establish a dynamic-statistical forecast model for May SC rainfall based on the relationship between the interannual variation of rainfall and large-scale ocean-atmosphere variables in the CFSv2. The sea surface temperature anomalies (SSTAs) in the northeastern Pacific and the central-eastern equatorial Pacific, and the 500-hPa geopotential height anomalies over western Siberia in previous April, which exert great influence on the SC rainfall in May, are chosen as predictors. Furthermore, multiple linear regression is employed between the predictors obtained from the CFSv2 and observed May SC rainfall. Both cross validation and independent test show that the hybrid model significantly improve the model's skill in predicting the interannual variation of May SC rainfall by two months in advance.
