Authors: Mustadi Ali
Published: July 2023

Learning community is the community among students, among teachers, students and teachers which learn collaboratively in schools. It leads to the strengthening of the character values of the students because it creates caring community. In learning community, there is no rivalry in learning and no competition among the students but they are collaboratively learning and caring to each other instead. There are 3 basic principals of learning community: 1) the right to learn, where every student has special uniqueness and potential and the teachers should give opportunities for each student to learn; 2) teachers do not teach but teachers learn; 3) education is for public, the class should be opened for public to observe. Those three basic principles become the basis in conducting school reform. School reform here means how schools build learning community where students and teachers learn to each other to create quality education, equality, and social harmony as the educational paradigm in 21st century.

This study investigates the relationship between the Human Development Index (HDI) and the Global Peace Index (GPI)  in the Middle East. This quantitative analysis employs the Pearson correlation coefficient formula, with HDI as the independent variable and GPI as the dependent variable. The literature review utilizes numerous sources, including journals, books, news media, and the internet. The research sample included Yemen, Afghanistan, Iraq, the United Arab Emirates (UAE), Palestine, Saudi Arabia, Syria, Qatar, and Israel. HDI and GPI are strongly negatively correlated (-0.854), indicating that an increase in one variable (HDI) diminishes the other variable (GPI). Consequently, countries in the Middle East with higher levels of human development tend to have lower GPI scores, indicating that higher levels of human development are associated with a greater likelihood of peace in this region.

Published: July 2023

Overt or concealed accessory pathways are the anatomic substrates of ventricular preexcitation (VP), Wolff–Parkinson–White syndrome (WPW) and paroxysmal supraventricular tachycardia (PSVT). These arrhythmias are commonly observed in pediatric age. PSVT may occur at any age, from fetus to adulthood, and its symptoms range from none to syncope or heart failure. VP too can range from no symptoms to sudden cardiac death. Therefore, these arrhythmias frequently need risk stratification, electrophysiologic study, drug or ablation treatment. In this review of the literature, recommendations are given for diagnosis and treatment of fetal and pediatric age (≤12 years) WPW, VP, PSVT, and criteria for sport participation.

We aimed to assess the natural history and clinical burden of moderate aortic stenosis and to investigate the interaction of patients’ baseline characteristics with prognosis.

Methods

Systematic research was conducted on PubMed. The inclusion criteria were inclusion of patients with moderate aortic stenosis; and report of the survival at 1-year follow-up (minimum). Incidence ratios related to all-cause mortality in patients and controls of each study were estimated and then pooled using a fixed effects model. All patients with mild aortic stenosis or without aortic stenosis were considered controls. Meta-regression analysis was performed to assess the impact of left ventricular ejection fraction and age on the prognosis of patients with moderate aortic stenosis.

Results

Fifteen studies and 11 596 patients with moderate aortic stenosis were included. All-cause mortality was significantly higher among patients with moderate aortic stenosis than in controls in all timeframes analysed (all P < 0.0001). Left ventricular ejection fraction and sex did not significantly impact on the prognosis of patients with moderate aortic stenosis (P = 0.4584 and P = 0.5792), while increasing age showed a significant interaction with mortality (estimate = 0.0067; 95% confidence interval: 0.0007–0.0127; P = 0.0323).

Conclusion

Moderate aortic stenosis is associated with reduced survival. Further studies are necessary to confirm the prognostic impact of this valvulopathy and the possible benefit of aortic valve replacement.

Background

The role of TAPSE/PASP, a measurement of right ventricular to pulmonary artery coupling, in patients hospitalized for acute heart failure (AHF) is poorly described.

Objectives

To evaluate the prognostic impact of TAPSE/PASP in AHF.

Methods

This retrospective single-center study included patients hospitalized for AHF between January 2004 and May 2017. TAPSE/PASP was evaluated as a continuous variable and as tertiles according to its value on admission. The main outcome was the composite of 1-year all-cause death or heart failure hospitalization.

Results

A total of 340 patients were included [mean age 68.8 ± 11.8 years; 76.2% men, mean left ventricular ejection fraction (LVEF) 30.4 ± 13.3%]. Patients with lower TAPSE/PASP had more comorbidities and a more advanced clinical profile, and received higher doses of intravenous furosemide in the first 24 h. There was a significant, linear, inverse relationship between TAPSE/PASP values and the incidence of the main outcome (P = 0.003). In two multivariable analyses including clinical (model 1), biochemical and imaging parameters (model 2) TAPSE/PASP ratio was independently associated with the primary end point [model 1: hazard ratio 0.813, 95% confidence interval (CI) 0.708–0.932, P = 0.003; model 2: hazard ratio 0.879, 95% CI 0.775–0.996, P = 0.043]. Patients with TAPSE/PASP greater than 0.47 mm/mmHg had a significantly lower risk of the primary end point (model 1: hazard ratio 0.473, 95% CI 0.277–0.808, P = 0.006; model 2: hazard ratio 0.582, 95% CI 0.355–0.955, P = 0.032; both compared with TAPSE/PASP <0.34 mm/mmHg). Similar findings were observed for 1-year all-cause mortality.

Conclusion

TAPSE/PASP on admission demonstrated a prognostic value among patients with AHF.

Aims

We aimed at investigating the long-term durability of the Epic bioprosthesis for surgical aortic valve replacement (SAVR) in a single-centre series of 888 implantations (2001–2018), expanding previous evaluations with shorter follow-up.

Methods

We retrieved prospectively collected in-hospital data and performed a systematic follow-up focusing on valve-related events (SVD, structural valve deterioration; PPM, patient–prosthesis mismatch; reoperation) (competing risks, CIF and Kaplan--Meier methods). We distinguished between SVD (permanent changes in valve function due to evolutive structural deterioration, ≥10 mmHg average gradient vs. reference echocardiography) and PPM.

Results

Average age at SAVR was 75.4 ± 7 years; 855 (96.3%) bioprostheses entered the follow-up and 396 (46.4%) were alive at last assessment. Follow-up was 99.9% complete, median duration was 7.7 years (entire cohort) and 9.9 years (survivors). At 10 years, overall survival was 50% ± 1.9, freedom from SVD was 99.4% ± 0.3 (competing risks) (seven SVD events after 8.1 ± 4.3 years). Freedom from SVD at 15 years was 98.4% ± 0.8 (competing risks). Prevalence of severe PPM was higher in 19 mm (6.5%) and 21 mm (10.2%) size cohorts. PPM (severe or moderate/severe) had no significant impact on overall survival (log-rank P = 0.27 and P = 0.21, respectively). Freedom from any reintervention (reoperation or TAVI Valve-in-Valve) for SVD at 10 years was 99.4% ± 0.3 (competing risks); freedom from any valve-related reintervention was 97.4% ± 0.6 (competing risks).

Conclusion

The Epic bioprosthesis for SAVR is limited by nonnegligible rates of PPM, which have nonetheless no impact on late survival. This device shows excellent durability and low rates of adverse valve-related events.
Trends in age- and sex-specific atrial fibrillation/flutter mortality in Italy between 2003 and 2017

Published: July 2023

Aims

We sought to assess the atrial fibrillation/flutter (AF/AFL) mortality rates and relative trends among the Italian population between 2003 and 2017.

Methods

Data regarding the cause-specific mortality and population size by sex in 5-year age groups were extracted from the World Health Organization (WHO) global mortality database. Decedents reporting the codes I48 were extracted accordingly to the International Classification of Disease-10 (ICD-10) coding system. The age-adjusted mortality rates (AAMRs), with relative 95% confidence intervals (CIs), also stratified by sex, were determined using the direct method. Joinpoint regression analyses were used to identify periods with statistically distinct log linear trends in AF/AFL-related death rates. To calculate nationwide annual trends in AF/AFL-related mortality, we assessed the average annual percentage change (AAPC) and relative 95% CIs.

Results

Over the study period, 90 623 (57 109 females) AF-related deaths were recorded. The AF/AFL AAMR increased from 8.1 (95% CI: 7.8–8.2) deaths per 100 000 to 18.7 (16.9–20.0) deaths per 100 000 population. Joinpoint regression analysis revealed a linear increase in age-standardized AF/AFL-related mortality [AAPC: +3.6 (95% CI: 3.0–4.3, P < 0.0001)] in the entire Italian population. Moreover, the mortality rate increased with age, showing a seemingly exponential distribution with a similar trend between males and females. Although the increase was more pronounced among women [AAPC: +3.7 (95% CI: 3.1–4.3, P < 0.0001)] compared with men [AAPC: +3.4 (95% CI: 2.8–4.0, P < 0.0001)], the difference did not reach statistical significance (P = 0.16).

Conclusions

In Italy, the AF/AFL-related mortality rates linearly increased from 2003 to 2017.

Aims

Recurrence of heart failure emerged as the main cause of long-term mortality in patients implanted with the HeartMate 3 (HM3) left ventricular assist device (LVAD). We aimed at deriving a possible mechanistic rationale of clinical outcomes and analyzed longitudinal changes in pump parameters over prolonged HM3 support to investigate long-term effects of pump settings on left ventricular mechanics.

Methods

Data on pump parameters (i.e. pump speed, estimated flow, and pulsatility index) were prospectively recorded in consecutive HM3 patients following postoperative rehabilitation (baseline) and then at 6, 12, 24, 36, 48, and 60 months of support.

Results

Data of 43 consecutive patients were analyzed. Pump parameters were set according to regular patients’ follow-up, including clinical and echocardiographic assessment. We recorded a significant progressive increase in pump speed over the course of support: from 5200 (5050–5300) rpm at baseline to 5400 (5300–5600) rpm at 60 months of support (P = 0.0007). Consistently with the increase in pump speed, a significant increase in pump flow (P = 0.007) and a decrease in pulsatility index (P = 0.005) were also recorded.

Conclusion

Our results reveal unique features of the HM3 on left ventricular activity. The need for progressive increase in pump support suggests indeed a lack of recovery and worsening of left ventricular function, which emerge as a possible mechanistic rationale of heart failure related mortality in HM3 patients. New algorithms to optimize pump settings should be envisioned to further improve LVAD-LV interaction and, ultimately, clinical outcomes in the HM3 population.
