The relationship between awareness and physical and mental health of people is direct and strong and is significant at the 95% confidence level. Since the Covid-19 disease is more effective on people with underlying diseases, therefore, if a person suffers from a chronic disease, it can make him sicker and therefore the person has less desire to get information about this disease, which reduces the level of awareness. and this issue is also true in relation to intellectual obsessions. In such a way that students with phobia or any other mental disorder deal with the subject more carefully. On the other hand, high awareness in people reduces the amount of stress related to the disease and improves the level of mental health and subsequently physical health. The results of this research also showed that the relationship between attitude and physical and mental health of people is direct but relatively weak, although it is significant at the 95% confidence level. Although mental and physical health increases the level of awareness, it does not have an effect on a person's perspective of an existing reality.

Fungal infections of respiratory system are the most common reason of death among immunosuppressed patients. Pulmonary candidiasis occurs as a primary bronchopneumonia or secondary type through blood diffusion. Primary bronchopneumonia of Candida, can also occur in patients which had been severely weakened due to tumors, neutropenic patients receiving extensive chemotherapy and infants with very low weight. Aspiration of infectious oral discharges in bronchi and their expansion in pulmonary parenchyma is the main pathway of transmission in Candida bronchopneumonia. In the current research, the most common fungi isolated from respiratory systems were Candida species (91.9%). We certified strains from 38 yeast species, which included almost all medically important yeasts, were cultured on the chromogenic medium and resulting colorful colonies were evaluated. The morphologies of the colonies on cornmeal agar considered as a primary guide for our identifications so then, four Candida species plus C. neopforman as shown at table 2 are the probable alternatives diagnosed in cases suspected to PJP. The results obtained in this work for yeast abundance complied with the findings of other researchers around the world, and indicated that there were almost similar patterns for yeast outbreak in different populations.

The academic period can be a stressful period due to the presence of many factors. In other words, it is a critical stage in the life of teenagers in every country and it is often associated with major changes in a person's life, especially in their social and human relationships. Being in such conditions is often combined with the pressures, worries and excitements of this period, it affects the performance and efficiency of people and finally, their mental health. On the other hand, freshness and vitality, the academic progress of girls and boys in elementary school is due to their mental health. Mental disorders have existed since the beginning of mankind, and no one is immune to them, and it is a danger that constantly threatens mankind. During the 20th century, human life has been transformed and changed more than in the entire history. The great effort for industrialization, expansion of urban life and machine life has had negative effects on people's health and has created new issues about health and disease, social, economic, political, cultural disorder and environmental, social and psychological problems. It has caused many pathological reactions. Mental health, in preventive psychology, social mental health or social psychiatry refers to all methods and measures that are used to prevent and treat mental illnesses and to rehabilitate existing mental patients. Behavioral disorders are a group of behaviors by which the patient repeatedly violates the fundamental rights of others or violates social rules. This disorder develops in childhood or adolescence and is more common in boys than girls. Behavioral disorders have relatively the same prevalence in different societies. Many children who have behavioral disorders, when they reach adulthood, their disorder is largely or completely resolved.

Process mixers and reactors are customized equipment with different capabilities that are designed and built for different pressure and temperature conditions according to process requirements. This equipment is available in atmospheric, pressure and vacuum, single-wall, double-wall and triple-wall types. The design and construction of these mixers is based on the latest standard editions of the American Society of Mechanical Engineers (ASME) and the use of up-to-date mixer technology and the creativity of the creativity of experienced mechanical engineers and (Pharmaceutical Equipment Department of mechanical engineers group - Petromana). According to the needs of these mixers and reactors, they can be used in various chemical, food, sanitary, cosmetic and pharmaceutical industries. Also, considering the necessary requirements in designing and manufacturing, injectable drugs are also widely used. All types of reactors and fermenters can be produced in the family of these products. All industrial mixers have a mechanism similar to a simple household device, they all have a power generator, power transmission, blades and a container for storing materials. Only in some types, the blade type changes depending on the ingredients that are to be mixed. The material input is a constant flow, just like a river with a very calm surface and a very turbulent depth. The liquid surface remains constant and does not mix well. In this situation, we have no choice but to change the type of blade. The available options are to design the same shaft in the liquid surface and increase the number according to the need and length of the shaft, for example, design the same shaft in the middle of the liquid, but what if the liquid becomes denser and thicker? In this study, hybrid mixers have been investigated.

The amount of solar energy received in Iran is estimated at an average of 18 mega joules per square meter per day or around 1016 mega joules per year in the country. This amount of energy is more than 4000 times the total energy consumed in the country. With this amount of received energy and having suitable lands for using the sun and the relatively simple technology of various applications of solar energy, all the energy needs of the country can be provided by using solar energy. Certainly, achieving a high yield requires spending more. Also, in cold regions, reaching a stable system requires the use of various pumps and valves. Therefore, an acceptable system is a system that results in a combination of high conditions, long life, low cost of maintenance and low cost of working conditions. In all existing solar systems, 1 or 2 water storage tanks can be used, provided that an electric element or another heat source is used in one of the tanks to compensate for heat loss resulting from static water. It is obvious that the heat loss caused by one tank is less than the heat loss caused by two storage tanks due to its smaller cross section. In the case of storage tanks, one should pay great attention to their insulation type so that it does not cause heat loss. The use of an auxiliary storage tank or a gas heating system or heating element in times of cloudy conditions will greatly help to compensate for the lack of available heat.

Introduction & Aim: The problem of crack formation during apical cavity preparation is one of the current challenges of endodontic problems. The purpose of this study was to investigate in vitro evaluation of effect of supporting bone on preventing cracks in roots resected by ultrasonic and bur.Materials and Methods: In this experimental study, 113 single-rooted human teeth with single canal and direct root were examined in the control group (40 teeth) and the experimental group (73 teeth). To evaluate the number of canals and the curvature of the root, P.A digital radiographs were prepared from buccolingual and mesiodistal directions. All teeth were evaluated for surgical microscopy in terms of crack, external analysis, and any defect. In all samples, the apical cavity was provided with diamond burs and a spray of air and then irrigated with sodium hypochlorite. In the control and experimental group, the samples were divided into two groups with of supporting bone and no of supporting bone. Each group was again divided into two subgroups (A, B). Then from the 3 mm apical portion of the roots, it was cut off by bur (subgroup A) and ultrasonic (subgroup B). The cut surface was examined by endoscopy microscope for presence or absence of crack.Results: All samples with supporting bone in both groups were free from cracks by ultrasonic and bur. In endodontic roots, without supporting bone, 92.86% in bur method and 90% in the ultrasonic technique, lacked cracks. In the control group, without bone support, 20% in the bur method and all the samples in the ultrasonically free of cracks.Conclusion: Supporting bone prevents cracking in endodontic roots by ultrasonic and bur.

Objective: Postoperative chronic pain (CPSP) is a common complication in musculoskeletal surgery. Physiotherapists usually treat patients with pain complaints before and after musculoskeletal surgery. The purpose of this article is (1) to identify the nature, process and importance of CPSPs; (2) expresses the need to understand and solve the group's difficulties. We use a full collaborative transformation model to analyze pain processes and pain management strategies. Method and materials: This study is a systematic review. Results: Physicians who understand how inflammation alters the function of the immune system can select pain targets for their patients. Clinicians should not assume that patients on multidrug therapy have a medical problem. Instead, the current approach is to manage pain using preventive strategies to reduce the severity of postoperative pain and minimize the development of CPSP. Conclusion: The role of biological, surgical, psychological, and patient factors in the transition to chronic pain requires further research to better understand their relationship to pain. Serious illness and drug use. Appropriate assessment and management of risk factors for CPSP requires a team discussion to describe the patient's experience of postoperative pain and to assess the pain that occurs during surgery.

Introduction: The aim of this study was to determine the outcome of low PTH after surgery and to monitor parathyroid recovery times in patients who underwent total thyroidectomy. Material and Methods: A commercially available PTH (iPTH) test was used to monitor iPTH levels on days 1 and 4. PTH levels were negative. It is determined by the same blood test as the sCa level. To exclude vitamin D deficiency, we first measured 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D levels in all patients Postoperative hypoparathyroidism was defined as postoperative albumin-adjusted sCa levels below 1.9 mmol/L (Convert to mg/dL, divide) with 0.25 (range of use, 2.10-2.60 mmol/L) symptoms of hypocalcemia (response to neuromuscular stress including paresthesias, muscle spasms, tetany or seizures) or sCa levels lower than results (1.9-2.1 mmol/L) with neuromuscular symptoms during the first 4 days after surgery. Results: In a multivariate logistic regression model, we found that patients who received an autograft of parathyroid tissue during surgery were more likely to have low PTH immediately after surgery (OR = 2.6; 95% CI, 1.8-3.8). Additionally, patients with parathyroid tissue who showed negative parathyroid tissue removal on the final pathology report were more likely to have postoperative PTH <10 pg/mL (OR = 2.2; 95% CI, 1.5 -3.3). Parathyroid tissue was the only risk factor for permanent hypoparathyroidism in the pathology report (OR = 3.6, 95% CI, 1.1–11.5). Conclusion: This study suggests that drug therapy should be considered in addition to PTH measurement, as 50% of patients with persistent hypoparathyroidism have elevated PTH levels to ≥10 pg/mL, but still want more help to avoid hypoparathyroidism. Symptoms of calcemia. In addition, 12 months may be the most appropriate time to define persistent hypoparathyroidism, as 5% of patients with low PTH resolve 6-12 months after treatment.

Introduction: Statins are powerful lipid-lowering drugs that have been shown to be effective in preventing heart disease and reducing the risk of death and heart attack. It is unclear whether hyperlipidemic patients undergoing coronary artery bypass grafting benefit from the lipid-lowering effects of statins. We sought to determine whether prior statin therapy could affect the outcome of hyperlipidemic patients undergoing coronary artery bypass grafting. Material and Methods: In this cross-sectional descriptive study conducted between 2012 and 2015, hyperlipidemia to mortality post anesthesia in patients who are candidates for coronary artery graft surgery was investigated. Results: Risk-adjusted multivariate logistic regression analysis showed that statin-treated hyperlipidemic (odds ratio, 0.42; 95% confidence interval, 0.26-0.69; P = .0007) ratio was 0.42; confidence interval, 0.26-0.69; P = .0007) was independently associated with a reduction in major in-hospital cardiac events, but not in-hospital mortality. A similarity score based on the previous 14 risk factors was performed to further control for bias. After similar correlations, randomized controlled trials confirmed that statin-treated hyperlipidemia and non-statin-treated eulipidemia were associated with reductions in major cardiovascular hospitalizations (difference odds ratio, 0.41; 95% confidence, 0.24-=0.71 [P. .0013] and odds) rate is 0. Conclusion: Although there was no increase in MACE in these normolipidemic patients who did not receive prior statin therapy, results from other CABG studies 6,7,8,9,16 and 25 in patients with heart disease were background in all patients who received CABG. LDL-C levels may benefit from long-term statin therapy. Although some of these patients did not see immediate short-term benefit, this study did not examine the long-term outcomes and future cardiovascular events of MACE. This group of patients may also benefit from a reduction in long-term MACE with statin therapy despite low preoperative LDL-C levels.

Introduction: Postoperative onset atrial fibrillation (POAF) is a common complication of coronary artery bypass surgery (CABG). However, the long-term risk of thromboembolism in patients who develop POAF after CABG surgery is unknown. Also, there is no information about stroke prevention in this setting. To investigate the long-term risk of stroke and thromboembolism in patients with new-onset POAF after initial CABG alone compared with patients with non-functional non-valvular atrial fibrillation (NVAF)Material and Methods: This study used data from the Clinical Cardiac Surgery Database and the Danish National Registry to identify patients undergoing a primary CABG procedure and de novo CABG between January 1, 2000 and June 30, 2015. The age, sex, CHA2DS2-VASc score and year of diagnosis of these patients were compared with dysfunctional NVAF between 1 and 4. Data analysis was performed between 2012-15. Proportion of patients starting oral anticoagulation within 30 days and thromboembolic rate.Results: 115 patients who developed POAF after CABG surgery and 115 patients who developed NVAF were compared. In the total population of 10,540 patients, the median (interquartile range) age was 69 years.2 (63.7-74.7) years; 8675 patients (82.3%) were male. 175 POAF patients (8.4% and 3549 patients with NVAF (42.9%). The risk of thromboembolism was lower in the POAF group than in the NVAF group (18.3 vs. 29.7 events per 1000 person-years; adjusted hazard ratio [HR], 0.55; 95% confidence interval, 0.32-0.95; P = .03) and NVAF (adjusted HR, 0.59; 95% CI, 0.68; P < .001) compared with patients not receiving anticoagulant therapy.Conclusion: Patients undergoing CABG surgery had a longer risk of thromboembolic new POAF than those undergoing NVAF. These data do not support the view that de novo POAF should be considered the same as primary NVAF in terms of long-term thromboembolic risk.
