Current Research Directions in Approaching the Effects Generated by of Corruption and Political Risk on Competitiveness and Organizational Performance
A dynamic environment involves change and innovation. The macroeconomic environment is
the ,,terrain’’ where all organisations economy compete. In a dynamic market, organisations need
to adapt quickly to changes and develop innovative ideas, products and services under the influence
of socio-economic factors to keep up with new trends.
The business environment brings together economic, social, cultural and political-institutional
components. Some factors directly influence organisational performance, while the influence of other
factors is only indirect. From an optimistic perspective, these factors can generate opportunities,
and from a pessimistic perspective, threats and challenges for the organisation.
The aim of this paper is to investigate and define corruption and political risk by identifying
influences on competitiveness and performance under the latest global trends in technological
development.
The main objective of the article is to define and review the current literature on the influence
of corruption and political risk on organizational competitiveness and performance
3-D Echocardiography Is Feasible and More Reproducible than 2-D Echocardiography for In-Training Echocardiographers in Follow-up of Patients with Heart Failure with Reduced Ejection Fraction
Left ventricular volumes (LVVs) and ejection fraction (LVEF) are key elements in the evaluation and follow-up of patients with heart failure with reduced ejection fraction (HFrEF). Therefore, a feasible and reproducible imaging method to be used by both experienced and in-training echocardiographers is mandatory. Our aim was to establish if, in a large echo lab, echocardiographers in-training provide feasible and more reproducible results for the evaluation of patients with HFrEF when using 3-dimensional echocardiography (3-DE) versus 2-dimensional echocardiography (2-DE). Sixty patients with HFrEF (46 males, age: 58 ± 17 y) underwent standard transthoracic 2-D acquisitions and 3-D multibeat full volumes of the left ventricle. One expert user in echocardiography (expert) and three echocardiographers with different levels of training in 2-DE (beginner, medium and advanced) measured the 2-D LVVs and LVEFs on the same consecutive images of patients with HFrEF. Afterward, the expert performed a 1-mo training in 3-DE analysis of the users, and both the expert and trainees measured the 3-D LVVs and LVEF of the same patients. Measurements provided by the expert and all trainees in echo were compared. Six patients were excluded from the study because of poor image quality. The mean end-diastolic LVV of the remaining 54 patients was 214 ± 75 mL with 2-DE and 233 ± 77 mL with 3-DE. Mean LVEF was 35 ± 10% with 2-DE and 33 ± 10% with 3-DE. Our analysis revealed that, compared with the expert user, the trainees had acceptable reproducibility for the 2-DE measurements, according to their level of expertise in 2-DE (intra-class coefficients [ICCs] ranging from 0.75 to 0.94). However, after the short training in 3-DE, they provided feasible and more reproducible measurements of the 3-D LVVs and LVEF (ICCs ranging from 0.89-0.97) than they had with 2-DE. 3-DE is a feasible, rapidly learned and more reproducible method for the assessment of LVVs and LVEF than 2-DE, regardless of the basic level of expertise in 2-DE of the trainees in echocardiography. In echo labs with a wide range of staff experience, 3-DE might be a more accurate method for the follow-up of patients with HFrEF
Adjunctive use of a nanocolloidal silver-based local antiseptic solution in the nonsurgical treatment of periodontitis: A split-mouth clinical study
Objectives. The aim of the present study was to evaluate the potential additional clinical benefit of a commercial nanocolloidal silver-based local antiseptic used as irrigation solution after subgingival mechanical instrumentation.
Material and methods. Periodontitis patients were treated following the current guidelines. Two randomly assigned hemiarches of each patient received subgingival mechanical instrumentation plus irrigations with the commercial product (experimental group); the other two hemiarches received mechanical instrumentation plus saline irrigations (control group). A clinical periodontal examination at baseline moment and after 3 months was performed.
The parameters considered for analysis were oral hygiene index (IHI), bleeding on probing score (BoP), periodontal pocket probing depth (PD), gingival recession (GR) and clinical attachment level (CAL). 72 sites were included in the analysis, the site with the highest PD/quadrant for each patient. Data were analyzed using GraphPad Prism version 8.0.1 (GraphPad Software Inc., La Jolla, CA, USA). p<0.05 was set as statistical significance level. Outcomes. Eighteen periodontitis patients were treated. All clinical parameters improved at re-evaluation, compared to baseline, both
in experimental and control group. The differences were statistically significant in terms of IHI, BoP and PD reduction. At re-evaluation, there were no statistically significant differences between periodontal parameters registered in the experimental and control sites.
Conclusions. The present study failed to prove an adjunctive clinical benefit of the antiseptic product in the nonsurgical treatment of periodontitis. These results support the gold standard role of subgingival mechanical instrumentation in the periodontitis’ therapeutic protocol
Characteristics of enrolment in an intensive home-visiting programme among eligible first-time adolescent mothers in England: a linked administrative data cohort study
Background: Intensive home visiting for adolescent mothers may help reduce health disparities. Given limited resources, such interventions need to be effectively targeted. We evaluated which mothers were enrolled in the Family Nurse Partnership (FNP), an intensive home-visiting service for first-time young mothers commissioned in >130 local authorities in England since 2007.
Methods: We created a population-based cohort of first-time mothers aged 13–19 years giving birth in English National Health Service hospitals between 1 April 2010 and 31 March 2017, using administrative hospital data linked with FNP programme, educational and social care data. Mothers living in a local authority with an active FNP site were eligible. We described variation in enrolment rates across sites, and identified maternal and FNP site characteristics associated with enrolment.
Results: Of 110 520 eligible mothers, 25 680 (23.2% (95% CI: 23.0% to 23.5%)) were enrolled. Enrolment rates varied substantially across 122 sites (range: 11%–68%), and areas with greater numbers of first-time adolescent mothers achieved lower enrolment rates. Mothers aged 13–15 years were most likely to be enrolled (52%). However, only 26% of adolescent mothers with markers of vulnerability (including living in the most deprived areas and ever having been looked after as a child) were enrolled.
Conclusion: A substantial proportion of first-time adolescent mothers with vulnerability markers were not enrolled in FNP. Variation in enrolment across sites indicates insufficient commissioning of places that is not proportional to level of need, with mothers in areas with large numbers of other adolescent mothers least likely to receive support
Right ventricle to pulmonary artery coupling after transcatheter aortic valve implantation—Determinant factors and prognostic impact
IntroductionRight ventricular (RV) dysfunction and pulmonary hypertension (PH) have been previously associated with unfavorable outcomes in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI), but little is known about the effect of right ventricle (RV) to pulmonary artery (PA) coupling. Our study aimed to evaluate the determinant factors and the prognostic value of RV-PA coupling in patients undergoing TAVI.MethodsOne hundred sixty consecutive patients with severe AS were prospectively enrolled, between September 2018 and May 2020. They underwent a comprehensive echocardiogram before and 30 days after TAVI, including speckle tracking echocardiography (STE) for myocardial deformation analysis of the left ventricle (LV), left atrium (LA), and RV function. Complete data on myocardial deformation was available in 132 patients (76.6 ± 7.5 years, 52.5% men) who formed the final study population. The ratio of RV free wall longitudinal strain (RV-FWLS) to PA systolic pressure (PASP) was used as an estimate of RV-PA coupling. Patients were analyzed according to baseline RV-FWLS/PASP cut-off point, determined through time-dependent ROC curve analysis, as follows: normal RV-PA coupling group (RV-FWLS/PASP ≥0.63, n = 65) and impaired RV-PA coupling group (RV-FWLS/PASP < 0.63, n = 67).ResultsA significant improvement of RV-PA coupling was observed early after TAVI (0.75 ± 0.3 vs. 0.64 ± 0.3 before TAVI, p < 0.001), mainly due to PASP decrease (p < 0.001). LA global longitudinal strain (LA-GLS) is an independent predictor of RV-PA coupling impairment before and after TAVI (OR = 0.837, p < 0.001, OR = 0.848, p < 0.001, respectively), while RV diameter is an independent predictor of persistent RV-PA coupling impairment after TAVI (OR = 1.174, p = 0.002). Impaired RV-PA coupling was associated with a worse survival rate (66.3% vs. 94.9%, p-value < 0.001) and emerged as an independent predictor of mortality (HR = 5.97, CI = 1.44–24.8, p = 0.014) and of the composite endpoint of death and rehospitalization (HR = 4.14, CI = 1.37–12.5, p = 0.012).ConclusionOur results confirm that relief of aortic valve obstruction has beneficial effects on the baseline RV-PA coupling, and they occur early after TAVI. Despite significant improvement in LV, LA, and RV function after TAVI, RV-PA coupling remains impaired in some patients, it is mainly related to persistent pulmonary hypertension and is associated with adverse outcomes
Biological Evaluation of Balneotherapeutic Mud and Sulfurous Mineral Waters: Insights from In Vivo and In Vitro Studies
Balneotherapy, treating diseases by bathing in mineral-rich waters and mud, has a long historical application across various cultures. Despite its widespread use, comprehensive studies on its biological impacts are scant, particularly in quantifying effects at the cellular and systemic levels. This study aims to rigorously investigate the biological effects of therapeutic mud and mineral waters, providing a scientific basis for their clinical application. We focused on elucidating the mechanisms behind the observed therapeutic effects and determining these natural resources' safety profiles. Employing a dual approach, we conducted both in vitro and in vivo studies. For the in vitro experiments, human fibroblast cells were treated with different concentrations of mud extracts to assess cytotoxicity, proliferation, and apoptosis pathways. For the in vivo assessments, Wistar rats were exposed to mud and mineral water treatments, with subsequent evaluations of biochemical markers in blood and urine indicative of systemic physiological changes. Our findings reveal that mud extracts exert a dose-dependent influence on cell viability, with low concentrations promoting cellular proliferation while higher concentrations induce apoptosis. In vivo treatments demonstrated significant modulation of inflammatory markers and oxidative stress parameters without evident systemic toxicity. The therapeutic mud and mineral waters demonstrate pronounced biological effects, enhancing cellular health and modulating systemic physiological responses without adverse side effects
