Increasing Use of Telemedicine for Neurological Disorders During the COVID-19 Pandemic: A Mini-Review

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly contagious viral infection. In addition to its association with common pulmonary and gastrointestinal complications, COVID-19 is also associated with numerous neurological and neuropsychiatric conditions. This minireview aims to cover current literature addressing the application of telemedicine in neurological disorders and neuropsychiatric conditions, especially in response to the COVID-19 pandemic. This article revealed that quarantine, masking, and social distancing policies practiced during the COVID-19 pandemic involved restrictions and challenges to providing medical services, especially for patients with neurological disorders with or without COVID-19 infection. During the pandemic, both healthcare administrators and clinicians, including neurologists, have rapidly adapted or introduced telemedicine technologies for delivering specialty care. In some areas in the world, telemedicine has been successfully applied to reduce the impact imposed by COVID-19. Conclusively, this article supports the idea that telemedicine is an effective tool for providing specialized healthcare for patients with neurological conditions while adhering to social distancing or lockdown policies instituted during the COVID-19 pandemic. Government and medical/healthcare authorities, physicians and healthcare providers need to work together to expand the adoption of telemedicine applications, even after the COVID-19 crisis.

Hybrid Distractor for Continuous Mandibular Distraction Osteogenesis

Distraction osteogenesis (DO) is a reconstruction method for repairing bone deficiencies in the oral and maxillofacial area. Manual DO techniques have shown the functionality of the DO method for bone tissue reconstruction. The DO method can improve treatment conditions, as well as the quality of the reconstructed bone, compared with conventional techniques. Recently, continuous DO devices have been proposed to enable an automatic DO process while using a continuous force for moving the bone segment (BS). Animal studies and clinical trials have shown the successful application of continuous distractors in terms of improving DO factors, including rate and rhythm. The continuous DO technique can shorten the treatment time and enhance the quality of the regenerated tissue. However, the developed continuous distractors are yet to be used in human applications. In this study, by combining motor-driven and hydraulic techniques, a hybrid distractor is proposed. The hybrid distractor is capable of generating a continuous distraction force while controlling the position of the BS in a linear vector, with a high positioning accuracy. Results of modelling and experimental study revealed that the proposed hybrid distractor met all required factors for enabling a continuous DO procedure in humans. The proposed distractor is capable of eliminating the drawbacks of exiting techniques in terms of generating and transferring a controlled distraction force to the BS. The wireless control, as well as the small size of the device, makes this device a suitable solution for use in the reconstruction of bone defects in the maxillofacial area in humans.

Association of Blood Pressure Indices with Right and Left Cardio-Ankle Vascular Index (CAVI) and Its Mathematically Corrected Form (CAVI0) for the Evaluation of Atherosclerosis

Background and Objectives: The cardio-ankle vascular index (CAVI) is an index for arterial stiffness that is theoretically independent of blood pressure. CAVI₀ is the mathematically corrected formula of CAVI that has been claimed to be less dependent on blood pressure changes. The association of right and left CAVI and CAVI₀ with blood pressure indices can reveal the importance of considering the blood pressure of the patient despite their theoretical independency. In this study, we assessed the right and left CAVI and CAVI₀ and evaluated the main effect of blood pressure indices on them with respect to age. Materials and Methods: We collected the following data of 136 community-dwelling individuals: age; sex; weight; height; body mass index; right and left CAVI and CAVI₀; and systolic (SBP), diastolic (DBP), and mean blood pressure (MBP). The association of right and left CAVI and CAVI₀ with blood pressure indices was evaluated using regression analysis. Results: Regression analysis revealed that SBP, DBP, and MBP were associated with right and left CAVI (independent of age). Moreover, SBP was associated with both right and left CAVI₀ (independent of age), whereas DBP was not associated with right or left CAVI₀. Conclusion: Right and left arterial stiffness measured using CAVI has no different associations with SBP, DBP, and MBP. Both right and left CAVI₀ were independently associated with SBP, whereas neither left nor right CAVI₀ was independently associated with DBP. MBP was only associated with the right-side CAVI₀ in community-dwelling individuals.

Establishing Core Competencies and a Professional Curriculum for the Care Service Department in Vocational High Schools in Taiwan

In response to the emergence of the aging society, the vocational high school education system in Taiwan has established a care service department since 2018. The purpose of this study was to develop core competencies and a professional curriculum for the care service department in vocational high schools. First, this study invited 20 experts and scholars to take part in a focus group to collect suggestions as the basis for the development of core competencies and a curriculum. Second, this study invited 10 experts and scholars to participate in three rounds of a Delphi survey to evaluate the planning for the development of core competencies and a curriculum that meet educational needs. In this study, we identified eight core competency constructs and 15 indicators across two dimensions relating to the care services taught in vocational high schools. We then designed 26 professional subjects according to the core competencies. We identified the core competencies for long-term care service education and devised a professional curriculum to foster the skills and knowledge among students that are required for successfully meeting the care needs of a rapidly aging society through work in the long-term care industry after graduation.

Review of physical stimulation techniques for assisting distraction osteogenesis in maxillofacial reconstruction applications

Distraction Osteogenesis (DO) is an emerging limb lengthening method for the reconstruction of the hard tissue and the surrounding soft tissue, in different human body zones. DO plays an important role in treating bone defects in Maxillofacial Reconstruction Applications (MRA) due to reduced side effects and better formed bone tissue compared to conventional reconstruction methods i.e. autologous bone graft, and alloplast implantation. Recently, varying techniques have been evaluated to enhance the characteristics of the newly formed tissues and process parameters. Promising results have been shown in assisting DO treatments while benefiting bone formation mechanisms by using physical stimulation techniques, including photonic, electromagnetic, electrical, and mechanical stimulation technique. Using assisted DO techniques has provided superior results in the outcome of the DO procedure compared to a standard DO procedure. However, DO methods, as well as assisting technologies applied during the DO procedure, are still emerging. Studies and experiments on developed solutions related to this field have been limited to animal and clinical trials. In this review paper, recent advances in physical stimulation techniques and their effects on the outcome of the DO treatment in MRA are surveyed. By studying the effects of using assisting techniques during the DO treatment, enabling an ideal assisted DO technique in MRA can be possible. Although mentioned techniques have shown constructive effects during the DO procedure, there is still a need for more research and investigation to be done to fully understand the effects of assisting techniques and advanced technologies for use in an ultimate DO procedure in MRA.

Factors Influencing Self-Efficacy and Self-Management among Patients with Pre-End-Stage Renal Disease (Pre-ESRD)

AIM

Chronic kidney disease (CKD) is an emerging major public health issue that leads to end-stage kidney disease (ESRD). Factors influencing the self-management and self-efficacy of ESRD patients are still under investigation. The objective of this study is to evaluate the association of depression and anxiety with self-management and self-efficacy in patients with pre-ESRD.

METHODS

Patients in the department of nephrology of a regional hospital in Taiwan were invited to participate and were included in our study if they had a confirmed diagnosis of early-stage CKD, were more than 20 years old, and could converse in Mandarin Chinese or Taiwanese. Patients diagnosed with depression, who could not execute self-care, or who had cognitive deficits were excluded. In total, this cross-sectional study included 112 pre-ESRD patients. We used the Chinese versions of the hospital anxiety and depression scale (HADS), the chronic kidney disease self-efficacy instrument (CKD-SE), and the chronic kidney disease self-management instrument (CKD-SM) as the questionnaire. Spearman's rank correlation and logistic regressions were used to analyze the data.

RESULTS

The top quartile of self-management and self-efficacy scores (28 patients) was defined as high self-management and -efficacy, respectively, and the lower three quartiles as low self-management and -efficacy. The logistic regression analysis showed that having depression decreased the odds of having high self-management by 75.4% and high self-efficacy by 75.1%. Having an education level of senior high school or above increased the odds ratios for having high self-management and high self-efficacy to 4.47 and 3.56 (all p-values < 0.05).

CONCLUSION

Controlling depression as well as increasing the level of education can potentially increase self-management and self-efficacy in pre-ESRD patients.

Use of the triglyceride-glucose index (TyG) in cardiovascular disease patients

Da Silva et al. showed that the triglyceride-glucose (TyG) index was positively associated with a higher prevalence of symptomatic coronary artery disease (CAD). TyG has been used in healthy individuals as a marker of insulin resistance. The use of this index as a marker of atherosclerosis in cardiovascular disease (CVD) patients might be influenced by diabetes and the hyperlipidemic state that led to CVD. Certain considerations might be necessary before we conclude that the TyG index can be used as a marker of atherosclerosis in CVD patients. These factors can highlight the role of fasting blood glucose and triglyceride levels that are used in the TyG formula. Comparing the fasting blood glucose and/or triglyceride levels with the TyG index in these patients to show how much value the TyG index can add to clinical practice seems to be necessary. Conclusions of such studies might be biased by these facts. Stratification by CAD disease category cannot help achieve an understanding of the role of TyG in CVD. Correlations do not imply causation, so the use of the TyG index as an index in CAD patients is questionable.

Lecca et al., in a recent publication in the Int. J. Environ. Res. Public Health had made some mistakes in the statistical analysis and interpretation of the results. Age was not a clear contributing factor in the prolongation of QT interval in the electrocardiogram (ECG), as there were strong confounders in their study. The effects of age were mainly faded out because of the age range of the participants. The use of Pearson’s correlation is questionable because of the normality assumptions was not met on the studied variables. They also made some conclusions about the effects of long and night shifts on the QT prolongation that were not appropriate based on their study type. All of these mentioned issues might completely change the validity of the conclusions they made.

Prediction of self-care behaviour on the basis of knowledge about chronic kidney disease using self-efficacy as a mediator

AIMS AND OBJECTIVES

This study was to investigate: (1) the important factors in the self-care of chronic kidney disease (CKD) patients and (2) the mediating effects of self-efficacy on knowledge and self-care.

BACKGROUND

Chronic kidney disease has become a major global health issue and is one of the top 10 leading causes of death in Taiwan where the dialysis population ranks first in the world. The number of patients with poor self-care behaviours continues to rise despite ongoing health education. Knowledge and self-efficacy are important factors that influence self-care behaviour; however, very few articles have examined the relationships among them.

DESIGN

Cross-sectional and correlational design.

METHODS

Subject recruitment was conducted by purposive sampling in the renal outpatient clinics and dialysis centres of two teaching hospitals in northern Taiwan. A total of 247 patients with chronic kidney disease (stages 1-5) were enrolled.

RESULTS

(1) Knowledge was positively correlated with self-efficacy (r = 0·41, p < 0·01) and with self-care (r = 0·18, p < 0·01). Self-efficacy (r = 0·44, p < 0·01) as well as age (r = 0·15, p < 0·01) were positively correlated with self-care. (2) The relationship between knowledge and self-care was fully mediated by self-efficacy (z = 4·82, p < 0·001) and the effect was 50%.

CONCLUSION

The results showed that self-efficacy was a crucial mediator between knowledge and self-care. In addition to providing knowledge to chronic kidney disease patients, healthcare professionals should also offer strategies that can enhance self-efficacy to increase self-care behaviours in chronic kidney disease patients and implement effective disease management.

RELEVANCE TO CLINICAL PRACTICE

Incorporate self-efficacy strategies into the process of health education to improve knowledge and the effectiveness of self-care. The findings of this study provide evidence of effectiveness of the use of group activity through self-management and self-efficacy enhancement programmes and may influence the policy makers to consider adding or modifying the reimbursement criteria.

Self-Management Programs on eGFR, Depression, and Quality of Life among Patients with Chronic Kidney Disease: A Meta-Analysis

PURPOSE

Chronic kidney disease (CKD) is a condition characterized by the gradual loss of kidney function over time. Self-management programs have been widely applied to chronic disease education programs, which are designed to delay deteriorating kidney functions, preclude depression, and improve quality of life. This study aims to analyze effectiveness of self-management programs in bettering CKD patients' eGFR, mitigating depression symptoms and improving quality of life in randomized control or clinical trials.

METHODS

Using key terms, a search was conducted in English-language, peer-reviewed journals on CKD that were published between 2002 and 2014 on databases including CINAHL, Cochrane Library, MEDLINE. The measurable variables included CKD patients' eGFR, depression, and quality of life. Random and fixed effects meta analysis were applied with standard error and correlation based measure of effect size.

RESULTS

Eight studies met the inclusion criteria. A self-management program significantly impacted CKD patients' depression and mental quality-of-life dimensions, with an effect size of .29 [95% confidence interval (CI) (0.07, 0.53)] and -.42 [95% CI (-0.75, -0.10)]. However, the intervention of a self-management program had no significant effect on patients' eGFR as well as physical quality-of-life dimensions, with effect sizes of .06 [95% CI (-0.69, 0.81)] and -.16 [95% CI (-0.81, 0.50)].

CONCLUSIONS

Self-management programs of patients with chronic kidney disease can improve the depression and mental quality of life. Aside from providing more objective evidence-based results, this study provides a reference for clinical health care personnel who tend to patients with CKD.
