Impact of the Community-Based Active Monitoring Program on the Long Term Care Services Use and In-Patient Admissions of the Over-74 Population

Introduction: Social isolation increases in the over-74 population and it is a risk factor for death and Long Term Care (LTC) use. In order to prevent the negative consequences of social isolation on this population community interventions focused on strengthening the social network should be intensified. The aim of this paper is to describe the impact on health care use of a Community-based pro-Active Monitoring Program (CAMP) providing phone monitoring to all the clients and home visits according to the individual’s needs. Methodology: In order to provide an evaluation of the program outcomes, the rates of clients’ hospitalization and admissions to Long Term Care facilities during 2011 have been assessed. The observed rates have been compared with expected ones calculated on available information for similar population. A cost-analysis has been also carried out to analyze the program sustainability. Results: The studied sample is made up by 1408 over-74 citizens followed up during 2011 in Rome (Italy) by CAMP. The cumulative observation time was 1362 p/y;61 individuals died during 2011 (death rate 4.3%). The hospital admission rate observed among CAMP’s clients was 254‰ (357/1408;CL95% ± 91‰), lower than the 282‰ reported for the over-74 population of Rome. This translates into 39 averted hospitalization. The LTC admission rate is also reduced among CAMP’s clients (9/1,408, 6.6‰ CL95% ± 0.8‰ vs. 9.7‰ reported for a comparable sample);it translates into 4 averted LTC admissions. The averted cost ranged between 47,153 € and 220,117 € according to the range of services used by the clients, which translates into a percentage of estimated cost reduction on yearly basis ranged between 3% and 12.5% of the whole cost of services used by the studied population. Discussion: The paper suggests the capacity of CAMP to reduce both the over-74 hospitalization rate and use of LTC. Cost analysis also indicates a cost reduction as a consequence of the CAMP implementation. Further studies including a control group and a detailed cost-benefit analysis are needed to check the program sustainability on larger population.

Efficacy,Safety and Characteristics of the Amplatzer Vascular Plug II and IV Utilization for Various Percutaneous Occlusions in Children under 10 Years

Objectives:We aim to describe the efficacy,safety,and characteristics of the Amplatzer Vascular Plug(AVP)II and IV“off-label”use for multiple cardiovascular occlusions in children under 10 years.Methods:Observational retrospective multicenter(2007–2020,6 centers)review of paediatric procedures using AVP II or IV.Results:A total of 125 children(49.6%aged≤1 year,147 lesions)underwent 136 successive procedures(success rate:98.5%)using 169 devices(109 AVP IV,60 AVP II).The mean device diameter was 7.7±3.2 mm(4–20 mm).The median AVP size to vessel diameter ratio was 1.3(0–2).The median age and weight at implantation were 1.0 year(0.01–9.98)and 8.4 kg(1–69).Procedures were heterogeneous(55 patent ductus arteriosus(PDA),28 collaterals,18 sequestrations,22 arteriovenous/veinovenous/coronary fistulas,6 vertical veins,6 conduits,5 ventricular septal defects,7 miscellaneous).Day 1 and 6-month occlusion rates were respectively 94.8%and 98.5%.Major adverse events(MAE)occurred in 5.2%of cases(no procedure-related deaths),and more frequently in weight≤5 kg(p=0.01),younger patients(p=0.03)during PDA closure(p=0.02)of tubular types(p=0.02)using larger devices(p=0.03)and AVP II(p=0.003).Independent predictor of MAE risk was a higher AVP diameter to patient weight ratio(Odds-ratio:2.33,95%confidence interval 1.31–4.13,p=0.004,optimal cut off:1.45).Conclusions:Both AVPs are safe and effective for percutaneous occlusions in children under 10.Such devices represent an alternative“off label”use for well selected paediatric patients.

Patient Safety Culture Post Covid-19 Pandemic: In Perspective of Millennials Human Capital Issues

Background: Patient safety is the core task of any healthcare business. As medical harm caused by hospitalisation is still on the rise and patient safety culture is a struggle. We aim to determine the nature of patient safety culture in a private hospital and explore some unique human resource problems in Malaysia. Methods: In our case study, we use the Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire to measure the 12 dimensions of patient safety culture. The survey received 281 respondents (76% response rate) from all the millennial frontline healthcare providers, including doctors, nurses and allied healthcare providers. The result of the survey was used as the basis to further explore the problems in this hospital. In-depth interviews, observation and document reviews were conducted in relation to human resource problems. This study used IBM SPSS 26 for Windows for statistical analysis and Atlas ti.8 for qualitative analysis of open comments. We used Interpretive Phenomenological Interpretation for analysis of data after triangulation. Results: The overall average positive response rate for the 12 patient safety culture dimensions of the HSOPSC survey was 64%. The result showed that the staff feels positively toward patient safety culture in this hospital. The dimension that received good performance is “Manager expectation”, “Management support for patient safety” and “Organisational learning”. The dimension with the poor performance was “Staffing”, “Frequency of error reporting”, “Teamwork across units”, and “Handoff and transitions”. The open comments indicated inadequate staffing and nursing retention issues. Interviews, observation and document reviews related to staffing reveal high turnover rates among millennial nurses, high overtime and on-call rates, chaotic units with procedures, doctors’ round, admission and discharges mainly in medical and surgical units causing distraction. Poor shared governance is the biggest challenges that need immediate attention post Covid-19 pandemic. Conclusions: The HSOPSC measurement gave valuable insights on patient safety culture in a private hospital in Malaysia. The overall perception of patient safety culture was satisfactory. The poor positive response rate for “Staffing” dimension and the open comments suggests a need for an urgent need for retention and human resource management strategies to prevent brain drain due to high turnover rates, especially among millennial nurses. The key factors causing dissatisfaction and brain drain among nurses are the lack of shared governance.

Impact of the landslide for a Relationship between Rainfall Condition and Land Cover in North Vietnam

This paper aims to evaluate the probability of landslide hazards using a physical model(TRIGRS:Transient Rainfall Infiltration and Grid-Based Region Slope-Stability)for a regional scale considering the variations of a triggering rainfall condition and land-cover under the climate change.There are certain uncertainties raising from the soil properties and soil depth determination,assumption of groundwater,as well as the same root cohesion for all tree cover in the forest-related region.However,the application of TRIGRS model in a regional scale would provide important references for the distribution of landslide prone area regarding scenarios about changes of weather condition and land cover situation.It thus would support local authorities in obtaining more adequate land planning strategies in a river basin to mitigate potential hazard from the slope failure issue.

Timberland Investing and Private Property Rights in the United States of America

Investments in rural land for agriculture, timber, and other natural resource purposes occur frequently and globally. Fundamental principles of liberty and property found in the United States of America’s (“US”) legal system, from its origins to recent US Supreme Court decisions, continue to positively benefit holders of real estate in the Southern US, through a deep-rooted public policy of supporting private property rights and rural economic development. This stable rule of law enhances the long-term adaptability and sustainability of timberland as an asset class. This article is a commentary. It combines legal research methodology with the observations and conclusions of the authors. Its purpose is to demonstrate that the existence of alienable, documentable ownership, and related property rights create inherent stability and security. These principles form the basis of a culture that is defined by the rule of law and is “open for business.” This business mindset is particularly prevalent in the Southern US.

Safety in Surgery:Evaluation of Safety and Efficiency in Use of Aminoglycosides in Acute Appendicitis

Background: Aminoglycosides are used as empirical antibiotic treatment of intraabdominal infections which are caused by Gram negative bacteria and for which the treatment of choice is surgery. Aminoglycosides maintain good efficacy against these bacteria and reduce the need for prescribing fluoroquinolone, cephalosporin and carbapenem antibiotics which contribute to the development of resistant bacterial strains. In recent years, several clinical trials and international guidelines have advised against the use of aminoglycosides owing largely to doubts about their effectiveness and to the concern for their known nephrotoxicity and ototoxicity. Aim: In our study, we aimed to prove whether aminoglycosides are appropriate agents in the treatment of acute appendicitis. Methods: Retrospectively, patients with acute appendicitis we included in the trial. Demographic characteristics, comorbidities, clinical signs and symptoms, the type of antibiotic and surgical treatment were analyzed. The effect of independent variables on the occurrence of complications was calculated using Student’s T-test and Fisher’s precise test. The effect of aminoglycosides on the loss of kidney function was determined by means of a linear regression method. Results: 300 patients proved acute appendicitis were included in the study. Univariate statistical analysis showed that the risk factors for postoperative complications in treating acute appendicitis were: age over 76 years (p Conclusion: Aminoglycoside antibiotics are a safe and effective treatment of acute appendicitis;our not published data are positive of AGs use in acute cholecystitis and left colon diverticulitis which requires surgery. If used for a limited time period, they do not increase the risk for kidney injury and remain a stable low level of all over complications.

Land Use/Cover and Naturalness Changes for Watershed Environmental Management(Southeastern Brazil)

Driving forces on the landscape require regional management and/or local actions, together with other external factors. To operationalize this approach, this paper carried out a comparative analysis of the naturalness dynamics of the Jacaré-Gua&#231u and Jacaré-Pepira watershed, based on land use/cover changes and a structural indicator of the landscape, over the 10-year (2004-2014), as support opportunities for improving its environmental planning and management. Land use/cover dynamics were obtained based on screen digitizing of LandSat imagery, using polygon manual digitalization. Naturalness scenarios of the watersheds, over the 10-year (2004-2014), were obtained based on Urbanity Indicator, which evaluates how much the natural landscapes are dominated by altered systems. The total area of watersheds showed a predominantly scenario, induced by anthropogenic agricultural and non-agricultural expansion areas, mainly by conversion of other land use/cover types in sugarcane cultivation. Despite the increase in natural vegetation areas, over the 10-year (2004-2014), Jacaré-Gua&#231u and Jacaré-Pepira watersheds are far from a sustainable condition. However Jacaré-Gua&#231u watershed presents a scenario of more committed naturalness due to the increase in Urbanity Index values ≥ 0.7. The historical process of land use occupation for agricultural production remains the main driving force of naturalness changes, occupying more than 70% of the total area of watersheds. These results have significant implications for fast urbanizing municipalities in providing key information about long term land use impact on the watershed structure and function, making it possible for policy makers, scientists and stakeholders to identify land uses which are hindered or enhanced under various scenarios of land use change over the time, and making it possible to explore the trade-offs between them to improve watershed management.

Agricultural pesticide use and food safety:California's model

Pesticides have been an essential part of agriculture to protect crops and livestock from pest infestations and yield reduction for many decades. Despite their usefulness, pesticides could pose potential risks to food safety and the environment as well as human health. This paper reviews the positive benefits of agricultural pesticide use as well as some potential negative impacts on the environment and food safety. In addition, using the case of California, we discuss the need for both residue monitoring and effective pest management to promote food safety. Twenty years＇ pesticide residue data from California＇s pesticide residue monitoring program were analyzed. Results showed that more than 95% of food samples were in compliance with US pesticide residue standards （tolerances）. However, certain commodities from certain sources had high percentages of residues above tolerance levels. Even when residues above tolerance levels were detected, most were at levels well below 1 mg kg^-1, and most posed negligible acute health risk. However, a few detected residues had the potential to cause health effects. Therefore, establishing an effective food residue monitoring program is important to ensure food quality throughout the marketplace.
