Use of handheld electrocardiograph (SnapECG) for the remote monitoring of arrhythmias

Objective

To investigate the value of a SnapECG monitoring in diagnosing arrhythmias compared with the conventional management.

Methods

In the first phase, the SnapECG and 12-lead electrocardiogram (ECG) were simultaneously adopted to detect arrhythmias in 439 hospitalized patients. The accuracies of the SnapECG in detecting different arrhythmias were assessed. In the second phase, 62 patients with palpitations were randomized to receive the SnapECG monitoring or conventional management for 3 months. The diagnosis rate, time of diagnosis, episodes before diagnosis, associated expenses, and scores of the modified European Heart Rhythm Association (EHRA), Self-rating Anxiety Scale (SAS), and the 36-item short-form health survey questionnaire (SF-36) were compared between groups.

Results

In the first phase, the SnapECG monitoring showed a sensitivity of 83.55% and specificity of 96.79% in identifying tachyarrhythmias, and a sensitivity of 95.29% and specificity of 97.54% in identifying bradyarrhythmias. In the second phase, 1642 ECGs were recorded by the SnapECG, among which 290 abnormal ECGs were identified. Compared with the conventional management, the SnapECG monitoring increased the diagnosis rate of symptomatic arrhythmias (70.97% vs. 19.35%, P < 0.05), shortened the time of diagnosis (48.26 ± 36.78 days vs. 71.45 ± 30.01 days, P < 0.05) and consequently reduced the episodes of symptomatic arrhythmias prior to establishing diagnosis. The scores of modified EHRA, SAS, SF-36 significantly improved at 3-month compared with their baseline levels in the SnapECG group.

Conclusions

Remote monitoring with the SnapECG can achieve early diagnosis of symptomatic arrhythmias. However, its sensitivity in identifying P-wave-related arrhythmias warrants further improvement.

Comparison between patient specific instrumentation and traditional technique in patients with total knee arthroplasty: An observational perspective study

Background

Total knee arthroplasty surgery (TKA) using prenavigated Patient Specific Instruments (PSI) technique represents one of the most recent technological evolutions in development of prosthetic surgery. The aim of this study was to evaluate kinematic and functional recovery of patients operated with prenavigated PSI technique compared to those operated with traditional technique.

Methods

A cohort of 20 patients is divided in two groups; some are operated with traditional technique (with NexGen Knee system) and others with prenavigated PSI technique (with eMP Knee system) at Asiago Hospital. Limb circumferences are measured for edema evaluation and different evaluation forms are provided to patients: SF-36, KSS pre-surgery (T0), KSS 15 (T1) and 45 days after surgery (T2). Gait Analysis is performed 60 days post-surgery, after leaving crutches.

Results

The analysis of KSS and SF-36 evaluation forms shows a greater improvement in PSI Evolution group in terms of articulation (comparison between T0 and T1), knee function and early return to physical and social activities. Pain is lesser in NexGen group, in an earlier phase, but 45 days after surgery (T2) there are no significant differences between two groups. Perception of general state of health improves more and earlier in NexGen. In NexGen group edema evaluation had significant differences at the level of prosthetic leg, but not in knee and thigh. Overall: the walking pattern is more physiological in PSI Evolution group.

Conclusions

The present study highlighted the superiority of prenavigated PSI technique over traditional technique in recovering functionality of prosthetic knee and in restoring a more physiological path pattern.

Mood disorders impaired quality of life but not the mortality or morbidity risk in stable coronary heart disease patients

Background: It was suggested that depression and anxiety might be associated with increased cardiovascular risk in both primary and secondary prevention. In stable coronary heart disease (CHD) patients, we aimed to assess prevalence of depression and anxiety, its relations to conventional risk profile and mortality or morbidity and to quality of life (QoL). Methods: We examined 969 patients, at least 6 months after myocardial infarction or coronary revascularisation. Depression or anxiety was assessed using a standard HADS (Hospital Anxiety and Depression Scale), while QoL by SF-36 (Short-Form-36 Questions) questionnaires. Follow-up was done to assess mortality in incidence of non-fatal cardiovascular event. Results: Both mood disorders were rather frequent; borderline depression or anxiety (HADS score 8-10) had 14.8 or 10.9% of patients, respectively; moderate-to-severe depression or anxiety (HADS score ≥11) had another 8.2 or 6.7% of patients. After adjustment for potential covariates impaired QoL (SF-36 score <40) was independently associated with depressive mood [odds ratio (OR) 6.08 (95%CI: 2.92-12.7) or anxiety [OR 8.66 (95%CI: 3.77-19.89)], as well as with combination of both disorders [OR 33.58 (95%CI: 15.5-72.6)]. Conventional risk characteristics remained virtually unrelated to mood disorders (with exception of angina pectoris). We found significantly higher incidence of major cardiovascular events in patients with anxious mood and marginally significant inferior survival in patients with depression, but any cardiovascular risk disappeared if adjusted for potential covariates (conventional risk factors, natriuretic peptides, angina pectoris.) Conclusions: Mood disorders severely affected QoL of stable CHD patients, but not their global cardiovascular risk.

Weight changes after total knee arthroplasty in Chinese patients: a matched cohort study regarding predictors and outcomes

Background

The purpose of this study was to compare 2-year BMI changes between patients undergoing simultaneous bilateral total knee arthroplasty (TKA), staged bilateral TKA, and unilateral TKA. We also sought to determine the predictors of weight change and whether clinically meaningful weight changes affected outcomes.

Patients and methods

This retrospective, single-institution study included 202 Chinese patients who received simultaneously bilateral TKA, staged bilateral TKA, or unilateral TKA from 2008 to 2015. There were 49 simultaneous bilateral TKAs, 52 staged bilateral TKAs, and a matched 101 unilateral TKAs.

Results

66.8% (135/202) of patients lost weight after TKA surgery. However, 20.7% (42/202) of patients experienced clinically meaningful weight loss (a BMI decrease of more than 5%). Paired t test showed that 2-year BMI was significantly lower than preoperative BMI (p < 0.001). Weight loss was significantly different between the surgical strategy (p < 0.001). Preoperative BMI and age were predictive of clinically significant weight loss or gain (p < 0.05). Multiple linear regression showed that post-operative weight loss was associated with better Western Ontario and McMaster Universities Osteoarthritis Index and SF-36 scores (p < 0.001).

Conclusion

Patients after TKA experience weight loss. Age and preoperative BMI predict clinically meaningful weight change. Simultaneous bilateral TKA is associated with higher likelihood of weight loss. Clinically meaningful weight loss experiences better patient-reported outcomes.

Assessment of health-related quality of life in Egyptian HCV-infected recipients after living donor liver transplantation

OBJECTIVE

Understanding issues pertaining to quality of life is essential for any disease, particularly in recipients of liver transplantation. The aim of this study was to evaluate the impact of liver transplantation on Egyptian recipients' health-related quality of life (HRQOL).

METHODS

A prospective study carried out at the Ain Shams Center for Organ Transplantation (Cairo, Egypt), including 35 recipients for the evaluation of HRQOL using short form 36 score (Arabic version) and Beck Depression Inventory scores pre-transplantation and 1 and 6 months afterwards.

RESULTS

The mean age of the recipients was 49.27 ± 8.16 years. Among them, 17 patients were highly educated. A statistically significant improvement in all dimensions of their HRQOL was observed after liver transplantation. Their physical functioning was 45.00 ± 34.34 before liver transplantation while after 1 and 6 months it was 57.50 ± 20.66 and 74.83 ± 19.27, respectively (P < 0.001). All 17 patients completed their first year after transplantation, showing a statistically significant improvement in all dimensions of their HRQOL one year after liver transplantation except that in mental health, role limitation due to emotional health emotional and social functioning domains.

CONCLUSION

HRQOL is an important aspect of liver transplantation that should not be neglected.
