Assessing pressure injury knowledge among Jordanian and Turkish nursing students: A cross-cultural comparison.

AIM: Pressure injuries, a prevalent issue in healthcare settings, have profound physical and emotional implications for patients and healthcare providers. However, further evidence is needed regarding the level of nursing students' knowledge of pressure injuries in the Middle East, a region where healthcare is rapidly evolving. This study examines the knowledge levels regarding pressure injuries among nursing students in Jordan and Turkey. MATERIALS AND METHODS: This cross-sectional study collected data from a randomly selected sample of 282 nursing students studying in two private and two Public Universities in Turkey and Jordan. Data was collected using a demographic survey and the Pressure Ulcer Knowledge Assessment Tool (PUKAT 2.0). RESULTS: The overall knowledge scores among students were alarmingly low, with significant differences between Jordanian and Turkish cohorts, with Turkish students scoring higher. Moreover, a significant difference was observed between students' knowledge levels from public and private universities in Jordan, but no difference was found between students of the two Turkish universities. CONCLUSION: The knowledge gap among nursing students regarding pressure ulcers is a critical issue that needs immediate attention. These findings highlight the urgent need for improved educational strategies and standardized competencies in this aspect. This study strongly advocates for changing teaching strategies and incorporating evidence-based pressure injury prevention education into nursing curricula, interprofessional education initiatives, and continuous professional development for faculty. These measures can significantly enhance nursing students' knowledge and improve patient care.

Investigation of burnout and quality of work life of cardiac surgery nurses: A cross-sectional study.

BACKGROUND: The care processes of cardiac surgery patients are difficult, complex and stressful. Nurses, who have an important role in the care of these patients, may experience burnout or poor quality of work life may be affected because of difficult care processes, and professional difficulties. AIM: This study analysed burnout and quality of work life in cardiac surgery nurses. STUDY DESIGN: This cross-sectional study was conducted with 68 nurses in the clinic and intensive care unit of a university hospital's cardiovascular surgery department. Clinical nurses care for inpatients in this department, while intensive care nurses care for patients in the intensive care unit. The 'Sociodemographic and Descriptive Characteristics of Nurses Form', 'Maslach Burnout Inventory' and 'Nursing Work Quality of Life Scale' were used to collect the data. RESULTS: The mean score of emotional exhaustion sub-dimension of Maslach Burnout Inventory was 15.25 ± 5.08 (min: 7, max: 27), the mean score of the personal accomplishment sub-dimension was 17.48 ± 4.90 (min: 8, max: 27), and the mean score of depersonalization sub-dimension was 5.60 ± 2.70 (min: 0, max: 13). The mean scores of the emotional exhaustion sub-dimension (t: -2.380, p: .020, risk ratio [RR]: 1.67, confidence interval [CI]: [14.21, 18.82]) and the personal accomplishment sub-dimension (t: -2.604, p: .011, RR: 1.00, CI: [16.08, 19.92]) were higher in intensive care nurses. The mean total score of the nursing quality of work life scale was 107.20 ± 14.60 (min: 72, max: 149). A negative statistically significant relationship was found between the mean scores of emotional exhaustion (r: -0.243, p: .045) and depersonalization sub-dimension (r: -0.325, p: .007) of the Maslach Burnout Scale and the mean total score of the nursing quality of work life scale. CONCLUSION: In this study, it can be said that cardiac surgery nurses had moderate levels of emotional burnout, personal accomplishment and quality of work life, and low levels of depersonalization. At the same time, it can be seen that intensive care nurses have higher levels of emotional burnout. The increased emotional burnout and depersonalization in nurses decreased the quality of work life. RELEVANCE TO CLINICAL PRACTICE: This study provided an understanding of burnout and quality of work life of cardiac surgery nurses. Strategies can be developed to reduce burnout and improve the quality of the work life of cardiac surgery nurses. Particular attention should be paid to intensive care nurses who experience more burnout on several sub-dimensions. This may be a good approach to improving the quality of patient care.

Common human leucocyte antigensassociated with the development of subacute thyroiditis and COVID-19.

PURPOSE: Case reports of subacute thyroiditis (SAT) following coronavirus disease-19 (COVID-19) have been reported. Because the relationship between SAT and human leucocyte antigen (HLA) alleles is known, we aimed to determine HLA alleles that may predispose a patient to coronavirus infection and/or post-COVID-19 SAT. METHOD: This retrospective study was conducted in 51 patients with SAT and 190 healthy bone marrow donor volunteers. HLA-A, -B, -C, -DRB1, and -DQB1 were genotyped using next-generation sequencing. The study population was grouped into four groups according to SAT and COVID-19 history. RESULTS: The frequency of HLA-DQB1*04:02 was higher in the COVID-19(-) participants than in the COVID-19(+) participants (=0.045). The presence of HLA-DQB1*04:02 was associated with a lower risk of developing COVID-19 in all groups. The frequencies of HLA-B*35:01, HLA-B*35:03, HLA-DRB1*12:01, and HLA-DRB1*14:01 were different in the SAT(+) group than in the SAT(-) group in COVID-19(-) group. The frequencies of HLA-C*12:03, HLA-DQB1*06:04, HLA-DRB1*13:02, and HLA-DRB1*13:03 were different in the SAT(+) group than in the SAT(-) group in the COVID-19 (+) group. The difference in the frequency of these HLA types remains significant when the four groups are included together as follows: In the COVID-19(+) group, the frequencies of HLA-DRB1*13:02, and HLA-DRB1*13:03 were higher in the SAT(+) group than in the SAT(-) group. In the COVID-19(-) group, the frequencies of HLA-B*35:03, HLA-DRB1*12:01, and HLA-DRB1*14:01 were higher in the SAT (+) group than in the SAT(-) group. CONCLUSION: HLA alleles associated with SAT susceptibility may vary with COVID-19 history.

Safflower protein as a potential plant protein powder: optimization of extraction and spray-drying process parameters and determination of physicochemical and functional properties.

BACKGROUND: The research about sustainable and alternative plant protein sources has accelerated with the increasing need for protein. Safflower meal has a potential to be used in protein production due to its high protein content. This research aimed to produce an alternative plant-based protein powder using safflower meal. Both extraction and spray-drying parameters of safflower protein powder production were optimized using response surface methodology to achieve maximum yield. Moreover, the physicochemical and functional properties of safflower protein were determined and compared with those of commercial protein powders (soy, sunflower, pea, fava bean, and rice). RESULTS: The optimum extraction conditions were found to be 33.06:1 mL-1 g solvent-to-meal ratio, pH 11.00, 23.34 °C extraction temperature, and 30.86 min extraction time, which were achieved with a protein yield response of 75.21%. The highest powder yield (51.28%) was recorded for drying conditions of inlet air temperature of 160.11 °C, aspiration rate of 54.17 m3 h-1, and feed flow rate of 16.01 mL min-1. According to the amino acid profile of safflower protein, the glutamic acid content (14 475 mg (100 g)-1) was highest, while the methionine content (96 mg (100 g)-1) was lowest. Moreover, safflower protein can be regarded as a high-quality protein due to its high essential amino acid ratio (41.55%). The experiments showed that safflower protein had high solubility and good foam and emulsifying properties. CONCLUSION: Safflower protein could be a nutritional and functional protein source for the food industry. © 2024 Society of Chemical Industry.

Perioperative Health Care Professionals' Knowledge of Evidence-Based Inadvertent Perioperative Hypothermia Management.

PURPOSE: To evaluate the perioperative health care professionals' knowledge of evidence-based inadvertent perioperative hypothermia management. DESIGN: A descriptive, cross-sectional study. METHODS: The research sample consisted of 219 perioperative nurses and anesthesia technicians working in the university hospital and participating in perioperative care. Data were collected by the researchers using a questionnaire that included descriptive characteristics of health care professionals and inadvertent perioperative hypothermia management between March and April 2021. Descriptive statistics, Shapiro-Wilk normality, Kruskal Wallis, Mann Whitney U, and Spearman correlation test were used to analyze the data. FINDINGS: In this study, only 29.2% of the health care professionals knew that the threshold value for inadvertent perioperative hypothermia was <36 °C. The mean knowledge score of health care professionals on the management of inadvertent perioperative hypothermia was 13.78 ± 3.47. The knowledge score of 79.5% of health care professionals was moderate level. A significant correlation was determined between inadvertent perioperative hypothermia management knowledge score and education status (P = .032), task (P < .001), and mean years in the profession (P = .02). CONCLUSIONS: The knowledge of the health care professionals working in the perioperative process about evidence-based practices related to inadvertent perioperative hypothermia management was determined to be moderate. We recommend increasing the level of knowledge of health care professionals by providing education on guidelines regarding inadvertent perioperative hypothermia management.

Determination of the Relationship Between the Development and Recurrence of Subacute Thyroiditis and Human Leukocyte Antigen Subtypes.

Background: There are several studies investigating the role of human leukocyte antigens (HLA) in the development and recurrence of subacute thyroiditis (SAT). The HLA subtypes associated with SAT were usually determined in a population-based manner and HLA-B*35, HLA-B*18:01, HLA-C*04:01, and HLA-DRB1*01 were detected to play a role in the disease susceptibility and prognosis. The aim of this study was to determine HLA alleles associated with the tendency of recurrence and prevention of SAT within the Turkish population. Methods: This prospective study was conducted with 51 SAT patients and 720 healthy bone marrow donor volunteers. HLA-A, -B, -C, -DRB1, and -DQB1 were genotyped using next-generation sequencing. Results: The frequency of HLA-A*02:09, HLA-B*35:01/35:02/35:03, HLA-C*04:01, HLA-DRB1*12:01, and DRB1*13:03 were associated with an increased risk of SAT development (Odds Ratio: 22.4, 9.5, 10.3, 4.2, and 3.5, respectively). While HLA-A*02:09, HLA-B*35:01, HLA-B*44:02 HLA-C*07:18, and HLA-C*16:04 were associated with nonrelapsing SAT, HLA-DR*12:01was associated with relapsing SAT. HLA-B*35:02, HLA-B*35:03, and HLA-C*04:01 were more frequent both in relapsing and nonrelapsing groups according to control group. The frequency of HLA-B*18:01, reported as a risk factor previously, was similar in the SAT and control groups (p = 0.959). HLA-DRB1*11:01 was associated with a lower risk of SAT development. Conclusions: Along with -B*358 and -C*04, HLA-A*02:09 was detected as an important risk factor for SAT development in our population. HLA-DRB1*11:01 appears to be the protective HLA subtype against SAT. HLA-A*02:09, HLA-B*35:01, HLA-B*44:02, HLA-C*07:18, HLA-C*16:04, HLA-DQ*06:03, and HLA-DR*12:01 subtypes can establish a tendency to relapsing or nonrelapsing SAT.

The effect of different pre-treatments on unformulated pulse-based milk analogs: physicochemical properties and consumer acceptance.

This is the first part of a study on developing pulse-based milk analogs using chickpea, faba bean, and cowpea as raw materials. The objectives of the present study were to determine the processing conditions for pulse-based milk analog production at laboratory-scale and to investigate the effects of some pre-treatments such as dry milling (control), soaking and wet milling, blanching, blanching and dehulling, vacuum, and germination on lipoxygenase (LOX) activity of the raw material and some physicochemical and sensory properties of the final products. Dry milling provided the lowest LOX activity and the highest yield while soaking and wet milling resulted in a substantial increase in LOX activity, lower product yield, and a final product with lower whiteness value, regardless of the pulse type. Germination caused a significant decrease in LOX activity in all pulse types, while milk analogs produced from germinated pulses received the lowest acceptability scores from consumers.

Should we reconsider high-risk features in thyroid ultrasonography?

OBJECTIVE: Round shape is generally considered to reduce the risk of malignancy according to recent guidelines. On the contrary, according to some reports, spherically shaped thyroid nodules are associated with a higher risk of malignancy. Thus, we aimed to evaluate the malignancy risk of solid round isoechoic nodules detected at thyroid ultrasonography and compare it with that of solid ovoid isoechoic nodules. METHODS: Between 2017 and 2022, solitary solid round isoechoic nodules with diameters ³10 and £25 mm at thyroid ultrasonography were retrospectively selected and enrolled in the study. Age, size, nodule volume, serum thyrotropin levels, thyroid antibody levels, and cytopathological and histopathological results were recorded. RESULTS: A total of 457 solitary solid isoechoechoic nodules from 457 patients (262 females and 195 males; median age, 59 [31-70] years) were selected, of which 203 were solid round isoechoic nodules, and 254 were solid ovoid isoechoic nodules. A total of 54 surgical operations were performed on 457 nodules, and 31 of them resulted in malignancy. From the 31 malignant results, 25 originated from solid round isoechoic nodules and the remaining 6 originated from solid ovoid isoechoic nodules (p<0.025). CONCLUSION: We found that round nodules have higher malignancy rates than ovoid nodules. We think that ultrasonographic risk stratification systems used to target the most suitable nodules for the necessary biopsies can be dynamically updated, and sphericity can be added as a parameter in patient-based decision-making.

Subacute THYROiditis Related to SARS-CoV-2 VAccine and Covid-19 (THYROVAC Study): A Multicenter Nationwide Study.

CONTEXT: The aims of the study are to compare characteristics of subacute thyroiditis (SAT) related to different etiologies, and to identify predictors of recurrence of SAT and incident hypothyroidism. METHODS: This nationwide, multicenter, retrospective cohort study included 53 endocrinology centers in Turkey. The study participants were divided into either COVID-19-related SAT (Cov-SAT), SARS-CoV-2 vaccine-related SAT (Vac-SAT), or control SAT (Cont-SAT) groups. RESULTS: Of the 811 patients, 258 (31.8%) were included in the Vac-SAT group, 98 (12.1%) in the Cov-SAT group, and 455 (56.1%) in the Cont-SAT group. No difference was found between the groups with regard to laboratory and imaging findings. SAT etiology was not an independent predictor of recurrence or hypothyroidism. In the entire cohort, steroid therapy requirement and younger age were statistically significant predictors for SAT recurrence. C-reactive protein measured during SAT onset, female sex, absence of antithyroid peroxidase (TPO) positivity, and absence of steroid therapy were statistically significant predictors of incident (early) hypothyroidism, irrespective of SAT etiology. On the other hand, probable predictors of established hypothyroidism differed from that of incident hypothyroidism. CONCLUSION: Since there is no difference in terms of follow-up parameters and outcomes, COVID-19- and SARS-CoV-2 vaccine-related SAT can be treated and followed up like classic SATs. Recurrence was determined by younger age and steroid therapy requirement. Steroid therapy independently predicts incident hypothyroidism that may sometimes be transient in overall SAT and is also associated with a lower risk of established hypothyroidism.

Combined levothyroxine and testosterone treatment for restoring erectile dysfunction in propylthiouracil-induced hypothyroid rats.

BACKGROUND: Sexual dysfunction may indicate severe endocrine diseases. Recent research has suggested a link between hypothyroidism, low testosterone (T) levels, and erectile dysfunction (ED); however, the exact cause is unknown. AIM: We sought to investigate possible beneficial effects of levothyroxine and T alone or in combination on ED in propylthiouracil (PTU)-induced hypothyroid rats. METHODS: Adult Wistar rats (n = 35) were divided into 5 groups: control, PTU-induced hypothyroidism, PTU + levothyroxine, PTU + Sustanon (a mixture of 4 types of T: propionate, phenylpropionate, isocaproate, and decanoate) and PTU + levothyroxine + Sustanon. PTU was given in drinking water for 6 weeks. Four weeks after PTU administration, levothyroxine (20 µg microgram kg/day, oral) and Sustanon (10 mg/kg/week, intramuscular) were given for 2 weeks. Serum levels of total T, triiodothyronine (T3), and thyroxine (T4) were determined. In vivo erectile response and in vitro relaxant responses were measured. Localization of neuronal nitric oxide synthase (nNOS), endothelial NOS (eNOS), and phosphodiesterase type 5 (PDE5) were determined using immunohistochemical analysis. The relative area of smooth muscle to collagen was measured using Masson trichrome staining. OUTCOMES: Outcome variables included in vivo erectile function, in vitro relaxant and contractile responses of corpus cavernosum (CC) strips; protein localization of eNOS, nNOS, and PDE5; and smooth muscle content in penile tissue. RESULTS: The rat model of hypothyroidism showed a significant decline in serum levels of total T, T3, and T4. Levothyroxine increased T3 and T4 levels, whereas Sustanon normalized only total T levels. Combined treatment enhanced all hormone levels. Rats with hypothyroidism displayed the lowest erectile response (P < 0.001 vs controls). Combined treatment returned reduced responses, while partial amelioration was observed after levothyroxine and Sustanon treatment alone. Acetylcholine (P < 0.01 vs controls), electrical field stimulation (P < 0.001 vs controls), and sildenafil-induced relaxant responses (P < 0.05 vs controls) were decreased in the CC strips from hypothyroid rats. The combined treatment increased the reduction in relaxation responses. Levothyroxine and Sustanon restored decreases in eNOS and nNOS expression in the hypothyroid group. There was no significant difference in PDE5 expression among groups. Monotreatment partially enhanced reduced smooth muscle mass, while combined therapy completely recovered. CLINICAL IMPLICATIONS: The combination of thyroid hormones and T is likely to be a therapeutic approach for treatment of hypothyroidism-induced ED in men. STRENGTHS AND LIMITATIONS: Beneficial effects of levothyroxine and Sustanon treatment were shown in vitro and in vivo in PTU-induced hypothyroid rats. The main limitation of the study was the lack of measurement of androgen-sensitive organ weights and luteinizing hormone, follicle-stimulating hormone, and prolactin levels. CONCLUSION: These findings demonstrate that neurogenic and endothelium-dependent relaxation responses are reduced by hypothyroidism, which is detrimental to T levels and erectile responses. Levothyroxine and Sustanon combination medication was able to counteract this effect.

Determination of Knowledge and Attitudes of Cardiac Surgery Nurses Regarding the Enhanced Recovery After Surgery Protocol.

PURPOSE: This study aimed to examine the knowledge and attitudes of cardiac surgery nurses regarding the enhanced recovery after surgery protocol. DESIGN: This was a descriptive, cross-sectional study. METHODS: The sample consisted of 50 nurses working in the cardiovascular surgery clinic of a university hospital in the province of Izmir, Turkey. A questionnaire consisting of three sections was prepared by the researchers to collect data. The first section of the form captured sociodemographic and descriptive characteristics; the second section examined the level of knowledge about the enhanced recovery protocol for cardiac surgery; the third section captured the nurses' attitudes regarding the enhanced recovery protocol. The questionnaire was distributed to the nurses and the research data were collected after a certain amount of time. Descriptive statistics, Mann-Whitney U test, Kruskal-Wallis test, and correlation analysis were used in the analysis of the data. FINDINGS: The mean age of the nurses was 31.26 ± 6.74 (min = 23, max = 47); 78% were female; 76% had a bachelor's degree; 48% were employed in the intensive care unit. The mean score of the nurses regarding their level of knowledge on the enhanced recovery protocol for cardiac surgery was 18.70 ± 5.29 (min = 0.00, max = 28.00); the mean score regarding attitude toward the enhanced recovery protocol after surgery was 30.00 ± 3.86 (min = 12.00, max = 33.00). There was a positive, moderate, statistically significant correlation (r = 0.396, P = .005) between the mean knowledge level score and the mean attitude level score. CONCLUSIONS: Results showed that nurses' knowledge was at a moderately positive level. Increasing the level of knowledge increased positive attitudes. Recommendations include disseminating protocol information and providing necessary training to increase positive attitudes in an effort to ensure protocol adherance.

Factors Affecting Knowledge Levels and Protective Behaviors to Prevent the Development of Skin Cancer in Organ Transplant Recipients as a High-Risk Group.

OBJECTIVES: Organ transplantrecipients are at high risk of skin cancer due to immunosuppressant therapy. This study investigated the factors affecting organ transplant recipients' knowledge and protective behaviors to prevent the development of skin cancer. MATERIALS AND METHODS: This was a cross-sectional descriptive study of kidney (n = 82) and liver (n = 31) transplant recipients seen at our hospitals in Turkey from June 2019 to February 2020. A sociodemographic and clinical characteristics form, the Skin Cancer and Sun Knowledge scale, the Sun Protection Behavior questionnaire, and the General Self-Efficacy scale were used to collect data. RESULTS: The mean age of organ transplant recipients was 46.63 ± 13.24 years. Self-efficacy and awareness that transplant increases the risk of skin cancer are 2 characteristics that affected the participants' knowledge level. The type of graft (kidney) affected participants' behavior in avoiding outdoor exposure between the hours of 10 am and 4 pm. Green/blue eye color and self-efficacy affected the participants' hatwearing behavior. These details showed that, as the patients' sensitivity and self-efficacy increased, their levels of knowledge and sun protection behaviors were positively affected. CONCLUSIONS: The knowledge level of patients was affected by (1) awareness that transplant is associated with an increased risk of skin cancer and (2) high levels of self-efficacy. We observed that (1) organ transplant recipients with high self-efficacy and kidney transplant recipients were more likely to avoid outdoor exposure between 10 am and 4 pm and that (2) organ transplant recipients with green/blue eyes and high levels of selfefficacy were more likely to wear a hat when outdoors. Organ transplant teams should provide education and counseling about skin cancer and sun protection in the follow-up care of transplant recipients.

The relationship between surgical intensive care unit nurses' patient safety culture and adverse events.

BACKGROUND: Adverse events are often encountered in surgical intensive care units (ICUs), and most of them occur due to preventable errors. Establishment of a patient safety culture is recommended for preventing and reducing these errors. AIMS: This study was performed to investigate the relationship between surgical ICU nurses' patient safety culture and adverse events. DESIGN: This was a cross-sectional descriptive study. METHODS: The study was performed in the surgical ICUs of four university hospitals in Izmir province, Turkey and was conducted in accordance with the Declaration of Helsinki and approved by an Ethics Committee. The sample comprised 113 nurses working in the surgical ICUs of the hospitals between November 2018 and February 2019. Data were collected using a questionnaire that comprised a demographic form, adverse events form, and patient safety culture hospital questionnaire. Student's t test, one-way analysis of variance, and logistic regression analyses were used to evaluate the data. P values <.05 were considered significant. RESULTS: At the end of the study, nurses' level of patient safety culture was found to be intermediate (65.5%), with the highest average positive response rate (PRR) obtained for teamwork within the units (65.5%) and the lowest average PRR obtained for the frequency of adverse event reporting (25.3%). There was a significant correlation between patient safety culture and adverse events (r = 0.027, P < .05). CONCLUSIONS: Surgical ICUs nurses' level of patient safety culture was average, and there was a significant correlation between patient safety culture and adverse events. RELEVANCE TO CLINICAL PRACTICE: Managers should establish a reliable system for reporting adverse events and encourage ICU nurses to report them. It is very important to adopt a non-punitive approach at instances when an adverse event is reported.

Evaluation of chronic pruritus and associated skin findings in patients with diabetes mellitus.

Background/aim: To explore the dermatological lesions associated with chronic pruritus in patients who were followed up at our clinic for type 1 and type 2 diabetes mellitus (DM). Materials and methods: The study population consisted of 249 patients with DM, who presented to the endocrinology clinic at Ankara University Faculty of Medicine between January 2022, and March 2022, regardless of whether they had reported experiencing pruritus symptoms. The visual analog scale and 5-D itch scale were used to determine the severity of itching in patients. Dermatological examination findings were also evaluated. Results: Of the 249 patients with DM, mean duration since diabetes was diagnosed was 12 ± 9.2 [median 10 (0.3-46)] years, and the mean HbA1c levels were 8.1% ± 2.1%. Pruritus was detected in 77 (30.9%) patients and the mean duration of diabetes diagnosis was 13.4 ± 9.7 years. Examination of the microvascular and macrovascular complications showed that the incidence of retinopathy, nephropathy, neuropathy and peripheral arterial disease was 31.2% (p = 0.003), 31.2% (p = 0.005), 66.2% (p < 0.001) and 10.4% (p = 0.038), respectively, in the group with pruritus. These incidences were significantly higher in the group with pruritus than in those without pruritus. Dermatological examination showed that the most common condition was xerosis (64%), followed by fungal skin infection (16%) and bullous pemphigoid (8%). No skin findings were noted in 7% of patients who complained of itching. Conclusion: Chronic pruritus may be associated with several factors such as poor glycemic control, high BMI and microvascular and macrovascular complications in patients with DM. Especially in patients with severe generalized pruritus who do not respond to standard antipruritic treatments, the use of DPP-4 inhibitors, a class of oral antidiabetic agents, should be questioned and all medications being used by the patient should be reviewed.

Should we reconsider high-risk features in thyroid ultrasonography?

SUMMARY OBJECTIVE: Round shape is generally considered to reduce the risk of malignancy according to recent guidelines. On the contrary, according to some reports, spherically shaped thyroid nodules are associated with a higher risk of malignancy. Thus, we aimed to evaluate the malignancy risk of solid round isoechoic nodules detected at thyroid ultrasonography and compare it with that of solid ovoid isoechoic nodules. METHODS: Between 2017 and 2022, solitary solid round isoechoic nodules with diameters ³10 and £25 mm at thyroid ultrasonography were retrospectively selected and enrolled in the study. Age, size, nodule volume, serum thyrotropin levels, thyroid antibody levels, and cytopathological and histopathological results were recorded. RESULTS: A total of 457 solitary solid isoechoechoic nodules from 457 patients (262 females and 195 males; median age, 59 [31-70] years) were selected, of which 203 were solid round isoechoic nodules, and 254 were solid ovoid isoechoic nodules. A total of 54 surgical operations were performed on 457 nodules, and 31 of them resulted in malignancy. From the 31 malignant results, 25 originated from solid round isoechoic nodules and the remaining 6 originated from solid ovoid isoechoic nodules (p<0.025). CONCLUSION: We found that round nodules have higher malignancy rates than ovoid nodules. We think that ultrasonographic risk stratification systems used to target the most suitable nodules for the necessary biopsies can be dynamically updated, and sphericity can be added as a parameter in patient-based decision-making.

Compliance of Health Professionals for Prevention of Inadvertent Perioperative Hypothermia in Adult Patients: A Review.

Inadvertent perioperative hypothermia is defined as a decrease in core body temperature below 36°C (96.8°F) in patients undergoing surgery, starting from one hour before anesthesia induction in the preoperative period, during the intraoperative period, and in the postoperative period in intensive care unit, spanning 24 hours. Inadvertent perioperative hypothermia is a preventable complication that occurs during surgery and can occur due to factors, such as open skin and abdominal cavity, general or regional anesthesia, prolonged surgery duration, low ambient temperature, use of cold irrigation or intravenous fluids, and factors related to the patient. Morbid heart problems, delayed wound healing, increased blood loss and blood transfusion, surgical site infection, deterioration in drug metabolism, and prolonged intensive care and hospital stay are some of the complications that may result from hypothermia. There are several international evidence-based practice guidelines for the prevention and control of hypothermia in the perioperative period. Although the guidelines state that hypothermia can be prevented with some simple and cost-effective measures implemented during the perioperative process, the compliance rate with these practices may be poor in clinical practice. In this article, the practices of healthcare professionals in preventing inadvertent perioperative hypothermia will be discussed in line with evidence-based guidelines.

Monitoring starch hydrolysis with micro visco-amylo-graph for the production of chickpea milk and optimization of the parameters with response surface methodology.

Plant-based milk products are gaining attention since it has been demonstrated that the consumption of animal-derived foods had to be reduced to combat global climate change. The production of plant-based milk includes a starch hydrolysis step for raw materials with high starch content such as cereals and pulses, since the gelatinized starch forms a thick slurry which causes an unsuitable consistency for a drinkable product. The objectives of this work were to investigate the effects of slurry concentration (solid to solvent ratio), enzyme including temperature, enzyme amount and mixing (rotation) speed on the pasting properties especially final viscosity of a crude chickpea milk and also to investigate the potential use of Micro Visco Amylo-Graph for monitoring starch hydrolysis. Response surface methodology, based on Box Behnken Design, was used to assess the parameters and to optimize the hydrolysis conditions for the minimum final viscosity. In conclusion, it was observed that slurry concentration and enzyme including temperature were the most critical factors that affect either the pasting properties or the final viscosity of the crude chickpea milk. Briefly, lower final viscosities were obtained from samples which were prepared at lower beginning concentrations and treated with higher enzyme amounts at lower temperatures.

Determination of insulin-related lipohypertrophy frequency and risk factors in patients with diabetes.

INTRODUCTION: Insulin, which is used in the treatment of diabetes mellitus (DM), may lead to the development of lipohypertrophy (LH) which can negatively affect the management of diabetes mellitus. Two common methods to detect LH are palpation and superficial subcutaneous ultrasonography (SSU). We investigated the frequency of non-palpable LH using SSU, as well as examining risk factors. METHOD: We included in our study patients who had been receiving insulin injections at least twice a day for over one year without palpable LH. The epidermis and the subcutaneous tissue thickness of each region were examined using SSU. The presence of LH and associated risk factors for LH were evaluated. RESULTS: We included 136 patients in our study. The mean age of all patients was 52.87±14.93 years, 59.6% were female and 73.5% had type 2 DM. The duration of DM and insulin usage were 15.76±9.20 and 11.42±8.26 years, respectively. The mean body mass index (BMI) of all patients was 30.59±7.40kg/m2. Non-palpable LH was detected in 87.5% (n=116) of the patients using SSU. In the multivariate logistic regression analyses, total cholesterol level, short-acting insulin dose and coronary artery disease (CAD) were associated with LH presence. CONCLUSION: Non-palpable LH can be seen at high rates in patients who have multiple insulin injections. Palpation is likely not enough to detect LH and we believe it would be appropriate to evaluate the presence of LH using SSU, especially for those who need high-dose insulin to control hyperglycaemia.

Vitamin D levels in patients with small and medium vessel vasculitis.

OBJECTIVES: To determine the prevalence of vitamin D deficiency in patients with small and medium vessel systemic vasculitis. METHODS: In this cross-sectional study, 25-hydroxy (OH) vitamin D3 levels were measured in adult patients with systemic small and medium vessel vasculitis including antineutrophil cytoplasmic antibody-associated vasculitis (AAV), cryoglobulinaemic vasculitis (CryV), IgA vasculitis (IgAV) and polyarteritis nodosa (PAN), and age- and sex-matched healthy subjects (HS) and patients with rheumatoid arthritis (RA) as control groups. 25OH vitamin D3 levels<30ng/ml and <20ng/ml were regarded as insufficiency and deficiency, respectively. RESULTS: Fifty-seven patients (42 AAV, 2 CryV, 8 IgA vasculitis, 5 PAN) with systemic vasculitis, 101 HS, and 111 RA patients were included. The mean 25OH vitamin D3 level was 21.8±14.2ng/mL in patients with vasculitis, 42.7±27.6ng/mL in HS (p<.001) and 20.1±18.47ng/mL in patients with RA (p=.54). Vitamin D insufficiency and deficiency were significantly higher in patients with systemic vasculitis compared to HS (75.4% vs 33.7%, p<.001; %50 vs 21.8%, p<.001, respectively). Vitamin D status was not different in patients with systemic vasculitis compared to RA. There was a negative correlation between vitamin D status and CRP levels (=-.364, p=.007). The multivariate logistic regression analysis showed that renal involvement was significantly associated with vitamin D deficiency/insufficiency in patients with vasculitis (OR 22.5 [95% CI 1.6-128.9]. CONCLUSION: Vitamin D deficiency and insufficiency are more frequent in patients with systemic small and medium vessel vasculitis and RA than HS. Renal involvement is one of the factors associated with vitamin D deficiency/insufficiency in patients with vasculitis.

Objetivos: Determinar la prevalencia de la deficiencia de vitamina D en los pacientes con vasculitis sistémica de pequeños y medianos vasos. Métodos: En este estudio transversal se midieron los niveles de 25-hidroxivitamina D3 en pacientes adultos con vasculitis sistémica de pequeños y medianos vasos, incluyendo vasculitis asociada a anticuerpos anticitoplasma de neutrófilos (AAV), vasculitis crioglobulinémica (CryV), vasculitis IgA (IgAV) y poliarteritis nodosa (PAN), y sujetos sanos pareados por edad y sexo (SS) y pacientes con artritis reumatoide (AR) como grupos control. Se consideraron insuficientes y deficientes los niveles de 25-hidroxivitamina D3<30ng/ml y <20ng/ml, respectivamente. Resultados: Se incluyeron 57 pacientes (42 de AAV, 2 de CryV, 8 de vasculitis IgA y 5 de PAN) con vasculitis sistémica, 101 SS y 111 pacientes de AR. El nivel medio de 25-hidroxivitamina D3 fue de 21,8±14,2ng/ml en pacientes con vasculitis, 42,7±27,6ng/ml en SS (p<0,001) y 20,1±18,47ng/ml en pacientes con AR (p=0,54). La insuficiencia y deficiencia de vitamina D fueron significativamente más altas en los pacientes con vasculitis sistémica en comparación con los SS (75,4 vs. 33,7%; p<0,001; 50 vs. 21,8%; p<0,001, respectivamente). El estatus de vitamina D no fue diferente en los pacientes con vasculitis sistémica en comparación con AR. Existió una correlación negativa entre el estatus de vitamina D y los niveles de PCR=−0,364; p=0,007. El análisis de regresión logística multivariante reflejó que el compromiso renal estuvo significativamente asociado a la deficiencia/insuficiencia de vitamina D en los pacientes con vasculitis (OR: 22,5; IC 95%: 1,6-128,9). Conclusión: La insuficiencia y deficiencia de vitamina D son más frecuentes en los pacientes con vasculitis sistémica de pequeños y medianos vasos y AR que en los SS. El compromiso renal es uno de los factores asociados a la deficiencia/insuficiencia de vitamina D en los pacientes con vasculitis.(AU)
