The correlation between death anxiety, loneliness and hope levels in patients treated in the cardiac intensive care unit.

BACKGROUND: A sense of hope plays an important role in relieving stress and psychological distress of cardiology patients, as well as improving their physical well-being. AIM: The aim of this study is to investigate the correlation between death anxiety, loneliness and hope levels in patients receiving treatment in a cardiac intensive care unit (ICU). DESIGN: This is a prospective, descriptive and correlational study. METHODS: The study was completed with 150 cardiac ICU patients in Istanbul, Turkey. The data were collected using a Patient Information Form, the Templer Death Anxiety Scale (TDAS), the Herth Hope Index (HHI) and the UCLA Loneliness Scale (UCLA-LS). RESULTS: The patients had a mean age of 63.56 ± 12.74 years. Most of the patients (82%) were treated in the ICU for heart failure. There was a statistically significant positive correlation between total scores of TDAS and UCLA-LS (r = .337; p < .001) and a statistically significant negative correlation between total scores of UCLA-LS and HHI (r = -.292; p < .001). Also, there was a statistically significant negative correlation between the scores of UCLA-LS and Positive Readiness and Expectancy Subscale (r = -.164; p = .044). The multiple linear regression indicated that the model was statistically significant (F = 7.177, p < .001). The variables of age and UCLA-LS among those included in the model were statistically significant predictors of the death anxiety scores of the patients (23.1%) (p < .05). CONCLUSIONS: The cardiology patients who received treatment in the ICU had a high level of death anxiety and moderate levels of loneliness and hope. The age and loneliness level were statistically significant predictors of death anxiety. RELEVANCE TO CLINICAL PRACTICE: It is recommended that individualized nursing care be planned and provided to conscious cardiology patients who are treated in the ICU, considering their age and loneliness levels and that nursing care be planned for individuals who are at risk of fear, anxiety, loneliness and hopelessness by periodically assessing their death anxiety, loneliness and hope levels.

Outcomes of COVID-19 infection occurring in the recovery period of the open-heart surgery.

Background: In this study, we aimed to examine the effect of novel coronavirus 2019 disease (COVID-19) on the healing process of patients undergoing open-heart surgery. Methods: Between October 2020 and May 2021, a total of in 22 patients (14 males, 8 females; mean age: 60±15 years; range, 18 to 82 years) who developed COVID-19 within the first 30 days after open-heart surgery were retrospectively analyzed. Since the study was conducted in the pre-vaccination period, all of the patients were unvaccinated. Demographic, operative, and laboratory data of the patients were analyzed, and morbidity and mortality rates were evaluated. Results: Postoperative COVID-19 infection occurred in 22 of 1,171 patients who underwent open-heart surgery. Pneumonia developed in 14 (64%) patients and mechanical ventilation support was required in 50% (n=7) of them. Mortality was seen in eight (36%) patients. Only procalcitonin level (p=0.003) and age (p=0.005) had significant effects on survival. Conclusion: Postoperative COVID-19 infection is associated with high pneumonia and mortality rates in unvaccinated patients. Protocols that can prevent false polymerase chain reaction negativity and early contamination can be life-saving.

Revascularization strategies in patients with infective endocarditis-related ST-elevation myocardial infarction: The STEMI-ENDO Registry.

OBJECTIVE: Infective endocarditis (IE)-related ST elevation myocardial infarction (STEMI) is extremely rare. A clear clinical consensus is lacking regarding the management of this emergency. In this study, we aimed to describe the clinical outcomes of treatment strategies in this patient population. METHODS: The study population comprised 19 retrospectively evaluated patients (nine women; mean age 52±11.8 years) with a diagnosis of IE-related STEMI. Transesophageal echocardiography detected vegetation in all the patients. The study population was divided into two groups on the basis of in-hospital mortality. RESULTS: Major clinical manifestations included dyspnea (89.5%), fever (78.9%), and chest pain (63.2%). Catheter-based coronary angiography was performed in all the patients. The causative agent was isolated in all the cases, and Staphylococcus aureus was identified in seven (36.8%). The most common infarction was in the left anterior descending artery (n=12 [63.2%]). The treatment strategy consisted of mechanical thrombectomy (n=1), valve replacement following stent implantation (n=5), direct balloon angioplasty (n=4), valve replacement along with coronary artery bypass grafting (CABG; n=6), and medical follow-up (n=3). Moreover, thrombolysis in myocardial infarction III flow was significantly higher in the survival group (100% vs. 0%, p<0.001). All these patients preferred CABG or stent implantation for revascularization. CONCLUSION: The current data suggest that a revascularization strategy with stent implantation or revascularization with CABG has a lower mortality rate in patients with IE-related STEMI.

Degradation, solubility and chromatographic studies of Ibuprofen under high temperature water conditions.

Ibuprofen (IBP) is an emerging environmental contaminant having low aqueous solubility which negatively affects the application of advanced oxidation and adsorption processes. It was determined that as the temperature increased to 473 K, the mole fraction solubility increased considerably from 0.02 × 10-3 to 212.88 × 10-3 (10600-fold). Calculation of the thermodynamic properties indicated an endothermic process, ΔsolH > 0, with relatively high ΔsolS values. Spectroscopic, thermal and chromatographic analyses established the IBP stability at subcritical conditions. In the second part of the study, the degradation of IBP in H2O2-modified subcritical was studied and the effect of each process variable was investigated. The optimum degradation of 88% was reached at an IBP concentration of 15 mg L-1, temperature of 250 °C, 105 min treatment time and 250 mM H2O2. The process was optimized by response surface methodology and a mathematical model was proposed and validated. Temperature was determined as the most influential parameter, followed by H2O2 concentration. At temperatures higher than 230 °C, a small but noticeable reduction in degradation % suggested that the OH· radicals are consumed at a higher rate than they are produced, through side reactions with other radicals and/or IBP by-products. Finally, potential by-products were determined by gas chromatographic-mass spectrometric analysis and potential by-products were proposed.

Consensus Report on Diagnosis, Treatment and Prevention of Infective Endocarditis by Turkish Society of Cardiovascular Surgery (TSCVS), Turkish Society of Clinical Microbiology and Infectious Diseases (KLIMIK), Turkish Society of Cardiology (TSC), Turkish Society of Nuclear Medicine (TSNM), Turkish Society of Radiology (TSR), Turkish Dental Association (TDA) and Federation of Turkish Pathology Societies (TURKPATH) Cardiovascular System Study Group.

Infective endocarditis (IE) is rare, but associated with significant morbidity and mortality rates. Estimates of the incidence of IE in Turkey are compromised by the absence of population-based prospective studies. Due to the frequent presence of predisposing cardiac conditions and higher rates of nosocomial bacteremia in highrisk groups, the incidence of IE is expected to be higher in Turkey. Additionally, while IE generally affects older people in developed countries, it still affects young people in Turkey. In order to reduce the mortality and morbidity, it is critical to diagnose the IE to determine the causative agent and to start treatment rapidly. However, most of the patients cannot be diagnosed in their first visits, about half of them can be diagnosed after three months, and the disease often goes unnoticed. In patients diagnosed with IE, the rate of identification of causative organisms is significantly lower in Turkey than in developed countries. Furthermore, most of the centers do not perform some essential microbiological diagnostic tests as a routine practice. Some antimicrobials that are recommended as the first-line of treatment for IE, particularly antistaphylococcal penicillins, are not available in Turkey. These problems necessitate reviewing the epidemiological, laboratory, and clinical characteristics of IE in our country, as well as the current information about its diagnosis, treatment, and prevention together with local data. Physicians can follow patients with IE in many specialties. Diagnosis and treatment processes of IE should be standardized at every stage so that management of IE, a setting in which many physicians are involved, can always be in line with current recommendations. Study Group for Infective Endocarditis and Other Cardiovascular Infections of the Turkish Society of Clinical Microbiology and Infectious Diseases has called for collaboration of the relevant specialist organizations to establish a consensus report on the diagnosis, treatment, and prevention of IE in the light of current information and local data in Turkey.

Does metformin affect mammographic breast density in postmenopausal women with type 2 diabetes.

Background: Increased mammographic breast density (MBD) is known to be associated with an increased risk of developing breast cancer.Aims: In this study, we aimed to research the possible relationship between MBD and metformin use in postmenopausal women diagnosed with type 2 diabetes mellitus (T2DM).Method: The patients were divided into two groups: women with T2DM and who were on metformin and women who were newly diagnosed with T2DM and had not yet taken metformin. MBD types are evaluated by a specialist radiologist.Results: Among the 74 women, 32 (43.2%) were in the group that did not use metformin and 42 (56.8%) were in the group of patients using metformin. The duration of breastfeeding (p = .0003), fasting blood glucose (p = .0003) and HbA1c (p = .0006) were statistically significantly higher in the group not using metformin. The quantitative mean ranks of the group members' MBD's were 41.81 in the metformin naïve group and 34.21 in the group using metformin (p = .12).Conclusions: In conclusion, metformin has no statistically significant effect on MBD in postmenopausal female patients with T2DM.

The follow-up results of newborn hearing screening of Gaziosmanpasa Taksim Research and Training Hospital.

AIM: This study aimed to present the results of newborns who were referred to advanced audiology centers after newborn hearing screening, and to determine concordance of our results with the American Academy of Pediatrics guidelines about the ages of hearing loss, aid fitting, and cochlear implantation. MATERIALS AND METHODS: A total of 7502 newborns were screened in Gaziosmanpasa Taksim Research and Training Hospital between March 2014 and June 2016 using the transient otoacustic emissions test as the first two steps and automated auditory brainstem response test for the third step. Newborns who had risk factors were screened using the automated auditory brainstem response only. Newborns who failed the screening tests were referred to advanced audiology centers. RESULTS: Of the 7502 newborns, 6736 (90%) completed the screening. The ratio of hearing loss was 0.08%. Six of 62 newborns who failed auditory brainstem response test and were referred to advanced audiology centers had severe bilateral hearing loss. One of the patients was not fitted with a hearing aid because the family refused it. The other one was not fitted an aid and did not undergo cochlear implantation because of severe and treatment-resistant acute otitis media. The age of diagnosis for the rest was before three months, and except for one patient, hearing aid fitting was before six months. The age of cochlear implantation was 12 months for two patients and 14 months for two patients. CONCLUSION: Ninety percent of patients completed the screening, the age of diagnosis for hearing loss was before three months and aid fitting was before six months, except for one patient. The results of the study were compatible with the diagnosis and treatment guidelines of the American Academy of Pediatrics.

The Evaluation of Nosocomial Infections in Pediatric Patients with Extracorporeal Membrane Oxygenation Support.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) has become a standard technique over the past few decades in intensive care unit (ICU). OBJECTIVE: A review of pediatric patients who received ECMO support in the pediatric cardiac ICU was conducted to determine the incidence, risk factors and causal organisms related to acquired infections and assess the survival rates of ECMO patients with nosocomial infections. METHODS: Sixty-six patients who received ECMO support in the pediatric cardiac ICU between January 2011 and June 2014 were included in the study. Demographic, echocardiographic, hemodynamic features and surgical procedures were reviewed. RESULTS: Sixty-six patients received a total of 292.5 days of venoarterial ECMO support. Sixty were postoperative patients. Forty-five patients were weaned from ECMO support with an ECMO survival rate of 68.2%. The rate of infection was 116.2/1000 ECMO days. Prolonged ICU stay, duration of ventilation and ECMO were found associated with development of nosocomial infection and only the duration of ECMO was an independent risk factor for nosocomial infections in ECMO patients. CONCLUSION: The correction of the underlying process leading to ECMO support and shortening the length of ECMO duration together with stricter application of ECMO indications would improve the infection incidence and hospital surveillance of the patient group.

Optimization of resistant starch formation from high amylose corn starch by microwave irradiation treatments and characterization of starch preparations.

The effects of microwave irradiation on resistant starch (RS) formation and functional properties in high-amylose corn starch, Hylon VII, by applying microwave-storing cycles and drying processes were investigated. The Response Surface Methodology (RSM) was used to optimize the reaction conditions, microwave time (2-4min) and power (20-100%), for RS formation. The starch:water (1:10) mixtures were cooked and autoclaved and then different microwave-storing cycles and drying (oven or freeze drying) processes were applied. The RS contents of the samples increased with increasing microwave-storing cycle. The highest RS (43.4%) was obtained by oven drying after 3 cycles of microwave treatment at 20% power for 2min. The F, p (<0.05) and R2 values indicated that the selected models were consistent. Linear equations were obtained for oven-dried samples applied by 1 and 3 cycles of microwave with regression coefficients of 0.65 and 0.62, respectively. Quadratic equation was obtained for freeze-dried samples applied by 3 cycles of microwave with a regression coefficient of 0.83. The solubility, water binding capacity (WBC) and RVA viscosity values of the microwave applied samples were higher than those of native Hylon VII. The WBC and viscosity values of the freeze-dried samples were higher than those of the oven-dried ones.

Prevalence of the metabolic syndrome in rheumatoid arthritis.

OBJECTIVE: Patients with rheumatoid arthritis (RA) experience a markedly increased prevalence of cardiovascular disease (CVD), but the causal factors have yet to be completely elucidated. Metabolic syndrome (MetS) is a cluster of risk factors of CVD and identifies additional cardiovascular risk beyond the sum of its individual components. In this study, we investigated the prevalence of MetS and its possible relationship with disease-related factors in patients with RA. MATERIAL AND METHODS: Fifty-two patients with RA and 30 age- and sex-matched healthy controls were studied. Adult Treatment Panel III of the National Cholesterol Education Program (NCEP-ATP III) and modified World Health Organization (WHO) criteria were used to define MetS. RA disease activity is assessed by the disease activity score of 28 joints (DAS28), and the functional status of patients was evaluated by Health Assessment Questionnaire (HAQ). RESULTS: Although there was no difference between groups regarding the frequency of MetS according to NCEP-ATP III criteria (17.3% and 6.5% in RA and control groups, respectively (p=0.158)) if modified WHO criteria were used, the prevalence of MetS was significantly higher in patients with RA (28.8%) than in controls (9.7%) (p=0.04). Central obesity and hypertension were found to be more frequent in patients with RA by both NCEP-ATP III and WHO criteria. RA patients with MetS had higher systolic and diastolic blood pressure, BMI and frequency of smoking than patients without MetS. Disease-related factors were similar in RA patients with or without MetS. CONCLUSION: The evaluation of patients with RA for MetS, which is a multidimensional risk factor of CVD, may be beneficial.

Farinograph properties and bread quality of flours supplemented with resistant starch.

Three different commercial starches (Hylon VII, Novelose 330 and CrystaLean) were incorporated into the bread formulation at different levels and their effects on the rheological and baking properties and resistant starch contents of breads were evaluated. Starch-supplemented doughs were weaker and absorbed more water than those of the base flour. Loaf volumes of the breads decreased above the 10% level for Novelose and above the 20% level for Hylon VII and CrystaLean supplementation. Commercial starches did not have a substantial deteriorative effect on crumb color, external appearance and symmetry of breads. Crust color values decreased at a 30% addition level in Novelose-supplemented and CrystaLean-supplemented breads and above a 10% addition level in Hylon VII-supplemented breads. Firmness of breads increased above the 10% level for Novelose and above the 20% level for Hylon VII and CrystaLean supplementation. Resistant starch contents of the breads (after 1 and 7 days storage) increased significantly as the addition level of commercial starches increased.
