Optimization of the mechanism from equipment for overcoming obstacles with design of experiments

A data collection considers how the experimental factors, controlled and uncontrolled, fit together into a model that will meet the specific objectives of an experiment and satisfy the practical constraints of resource and time. Customizing any product to improve performance requires a reliable method to measure performance results, in order to accurately assess the effects that design changes have on them. This paper has the purpose to analyse the equipment for overcoming obstacles. A comprehensive approach to model equipment requires performance data related to the design parameters. Slipping, slanting, becoming unstable, sliding, overturning and blocking while climbing steps and stairs are common problems and may cause instability for the user of the equipment. The Taguchi Method is used to optimize several parameters of the proposed mechanism and to ensure the stability through horizontality of the equipment. This method provides an opportunity to reduce the number of required sample size and is implemented by an orthogonal experimental array which enables the effect of multiple parameters to be simultaneously assessed

Traceability - an important step in food safety

Traceability is a topical issue used in the food processing industry, ensuring the economic operator the safety of purchasing raw materials from the external and internal market for their transformation into safe food products that reach the consumer's table. Traceability also emphasizes customer brand protection requirements. Traceability and withdrawal procedures are currently the most important in every segment of the food industry, as it must be ensured that their traceability efforts are at the highest standard to protect the brand image on the market. These growing requirements are pushing food processors to maintain traceability upstream and downstream in the supply chain. Given the expansion of the global market and the speed with which goods move around the world, it is understandable that the authorities are increasingly concerned with developing rules on traceability. There are priority approaches in the field of food, which have the greatest impact on consumers, given the frequency of consumption and the imperative nature of the need for food. , respectively: European Food Safety Authority - EFSA (Europe) and the National Sanitary Veterinary and Food Safety Authority - ANSVSA (Romania) [12,13]

Fish meat – a potential danger for consumers`health

Fish is an excellent source of Omega 3 protein and fatty acids, which have the property of reducing cholesterol, maintaining a healthy heart, and even helping to prevent depression. Also, meat fish is a lean meat with low calorie but delicious assortment of meat, and is recommended in the consumer's diet . The fish content vitamins (A, D, E, B12), minerals (phosphorus, iodine, potassium) and healthy fats that can not be synthesized in the human body and must be fed through food. How healthy the fish meat is, the more dangerous it can be in terms of its safety for the consumer, and more precisely the presence of parasitic hazards. The main objectives of this paper are to describe the parasitic hazards of fish meat to indicate the proper preparation of fish meat and to increase consumer awareness of the risks associated with the consumption of this type of meat, threats of parasitic nature. Avoiding the consumption of untreated or poorly treated fish meat is one of the preventive measures that need to be taken to avoid fish parasites

The importance of implementing a HACCP plan in food service operations and restaurants

The European Union has shown that the post-industrial market economy has led to the production of food products above the level of consumer needs in the member states. This development has generated new types of issues, due to the production of food at industrial scale. In order to cope with food and nutrition illnesses and to restore consumer confidence in food safety, the European Commission has launched a series of new legislative amendments on food safety (Marin V. et al, 2007). The Good Hygiene Practices Guide in restaurants establishes, according to the legislation in force, a set of rules referring to the part of food hygiene, which must be followed and applied in restaurants. Potential risks of contamination of food and/or beverages are identified in these plans and a series of measures are developed to prevent these risks. The plan also includes the hygiene rules that must be observed by the employees and the kitchen staff. Operators operating in the field of food must guarantee for its products, comply with the legislative requirements and permanently implement these requirements, in order to release for consumption safe products for the final consumer. The purpose of this paper is to keep in mind the scope of this study focusing on the storage, handling, processing and distribution of all products, including the cooked product to be consumed. Thus, all biological, chemical or physical hazards that may occur during the cooking process of the product are taken into account. The HACCP team will ensure that all foodstuffs used in the preparation of cooked products comply with food safety legislation

Open Coronary Endarterectomy of Left Anterior Descending Artery—Case Report and Review of Literature

Coronary endarterectomy (CE) emerged as a necessity to achieve complete surgical myocardial revascularization in patients with diffusely diseased coronary arteries and it also serves as aid to coronary bypass grafting (CABG). The safety and postoperative prognosis of this procedure are still matters of debate. There are no clear preoperative indications, a standard technique has not yet been established as gold standard and the postoperative management differs depending on each institution. CE of the left anterior descending artery (LAD) is technically challenging and potentially hazardous with high risk of postoperative myocardial infarction. In this article, we describe the open technique for CE of the LAD with its specific details, which we believe could be the safest and the best reproductible option. To better understand the profile of a patient requiring such a procedure we present the case of a 73-years old male with diffused coronary artery disease (CAD) and a short review of literature

Surgical Strategy for Sternal Closure in Patients with Surgical Myocardial Revascularization Using Mammary Arteries

Background: Coronary artery bypass grafting has evolved from all venous grafts to bilateral mammary artery (BIMA) grafting. This was possible due to the long-term patency of the left and right internal mammary demonstrated in angiography studies compared to venous grafts. However, despite higher survival rates when using bilateral mammary arteries, multiple studies report a higher rate of surgical site infections, most notably deep sternal wound infections, a so-called “never event”. Methods: We designed a prospective study between 1 January 2022 and 31 December 2022 and included all patients proposed for total arterial myocardial revascularization in order to investigate the rate of surgical site infections (SSI). Chest closure in all patients was performed using a three-step protocol. The first step refers to sternal closure. If the patient’s BMI is below 35 kg/m2, sternal closure is achieved using the “butterfly” technique with standard steel wires. If the patient’s BMI exceeds 35 kg/m2, we use nitinol clips or hybrid wire cable ties according to the surgeon’s preference for sternal closure. The main advantages of these systems are a larger implant-to-bone contact with a reduced risk of bone fracture. The second step refers to presternal fat closure with two resorbable monofilament sutures in a way that the edges of the skin perfectly align at the end. The third step is skin closure combined with negative pressure wound therapy. Results: This system was applied to 217 patients. A total of 197 patients had bilateral mammary artery grafts. We report only 13 (5.9%) superficial SSI and only one (0.46%) deep SSI. The preoperative risk of major wound infection was 3.9 +/− 2.7. Bilateral mammary artery grafting was not associated with surgical site infection in a univariate analysis. Conclusions: We believe this strategy of sternal wound closure can reduce the incidence of deep surgical site infection when two mammary arteries are used in coronary artery bypass surgery

Rare Cause of Severe Mitral Regurgitation after TAVI: Case Report and Literature Review

Pre-procedure mitral regurgitation (MR) is a frequent coexistent finding in patients undergoing transcatheter aortic valve replacement (TAVR), and most of them (up to 55%) experience a significant improvement in MR after the procedure. Although seldom described, mitral valve perforation after TAVR is a potentially serious complication that physicians should be aware of, as moderate or severe MR in TAVR recipients is associated with a high early mortality rate. We herein describe the case of a 65-year-old man presenting with worsening heart failure symptoms 5 months after TAVR due to an intraprocedural anterior mitral leaflet perforation and discuss the diagnostic process and therapeutic course of the case. Furthermore, we draw attention to the essential role of echocardiography in the management of TAVR procedures, taking into account its ability in detecting early complications, and emphasize the value of CT as a main determinant to predict long-term MR improvement after TAVR and to assess the potential candidates for double valve repair with percutaneous techniques

Same Clinical Reality of Spontaneous Rupture of the Common Iliac Artery with Pseudoaneurysm Formation—Comparison of Two Therapeutical Solutions, Endovascular Stent-Graft and Open Surgical Correction, for Two Cases and Review of the Literature

The incidence of isolated iliac artery aneurysms is approximately 2% and common iliac artery pseudoaneurysms are even rarer. A pseudoaneurysm is a localized hemorrhage as opposed to an actual aneurysm, which affects the entire vascular wall. They are typically asymptomatic and only detectable accidentally while looking for other causes. If large and symptomatic, they typically exhibit pressure symptoms as a result of the compression of the structures around them. Common symptoms include generalized stomach pain, urological problems, gastrointestinal bleeding, and neurological symptoms such as leg paralysis or sciatica-like back pain. Rarely, they may exhibit hemodynamic instability together with an aneurysm rupture, which has a high fatality rate. Due to the unique presentation, the diagnosis is typically rarely made and there is little experience with treating it. We report two cases of common iliac artery pseudoaneurysm found in two patients who had no notable medical history and who we chose to repair through the endovascular technique in the first case, an approach that has gained more ground for vascular repair worldwide, making it the current go-to method, and for the second case we chose a more traditional approach, through open surgery
