J Perianesth Nurs 2021 Apr 26. Epub 2021 Apr 26.

Department of Anesthesia and Reanimation, Sabuncuoğlu Şerefeddin Research and Training Hospital, Amasya University, Amasya, Turkey.

Purpose: The aim of this study is to investigate the effects of preoperative oral intake of liquid carbohydrate on postoperative stress parameters (blood glucose, insulin resistance, cortisol, noradrenaline, and adrenaline levels) in patients who underwent laparoscopic cholecystectomy.

Design: This is an experimental study with intervention and control groups.

Methods: The sample consisted of 68 patients who underwent laparoscopic cholecystectomy (control group = 33; intervention group = 35). Twelve-hour preoperative fasting was applied to the patients in the control group in accordance with the clinical routine. Clear oral liquid carbohydrate (400 mL; 12.5 g/100 mL maltodextrin, 50 kcal/100 mL, pH 5.0) was administered to the patients in the intervention group at the preoperative second hour. Blood samples were taken from the patients at the preoperative 2nd and postoperative 2nd and 24th hours, and their blood glucose, insulin resistance, cortisol, noradrenaline, and adrenaline levels were measured.

Results: Preoperative oral intake of carbohydrate had no effect on blood glucose (P > .05) but decreased insulin resistance at the postoperative 24th hour (P = .044; intervention and control group: 3.62 ± 3.44 to 8.16 ± 12.57 respectively) and cortisol level at the postoperative 2nd hour (P = .005; intervention and control group: 15.16 ± 6.53 mg/dl to 20.14 ± 7.49 mg/dl, respectively). In all of the three measurements, we found that the noradrenaline level of the patients in the intervention group was higher than the value of those in the control group (319.80 ± 301.49 pg/mL to 211.65 ± 141.11 pg/mL [P = .450]; 361.40 ± 213.50 pg/mL to 216.13 ± 114.53 [P = .001]; 268.40 ± 164.04 pg/mL to 196.00 ± 83.33 pg/mL [P = .026], respectively). Preoperative oral intake of liquid carbohydrate had no effect on postoperative adrenaline level (P > .05).

Conclusions: Oral intake of liquid carbohydrate given at the preoperative 2nd hour decreased postoperative stress response through insulin resistance and cortisol.

Patterns of Psychological Responses among the Public during the Early Phase of COVID-19: A Cross-Regional Analysis.

Int J Environ Res Public Health 2021 04 14;18(8). Epub 2021 Apr 14.

Clinic for Psychiatry, Clinical Center of Montenegro, 81110 Podgorica, Montenegro.

This study aimed to compare the mediation of psychological flexibility, prosociality and coping in the impacts of illness perceptions toward COVID-19 on mental health among seven regions. Convenience sampled online survey was conducted between April and June 2020 from 9130 citizens in 21 countries. Illness perceptions toward COVID-19, psychological flexibility, prosociality, coping and mental health, socio-demographics, lockdown-related variables and COVID-19 status were assessed. Results showed that psychological flexibility was the only significant mediator in the relationship between illness perceptions toward COVID-19 and mental health across all regions (all s = 0.001-0.021). Seeking social support was the significant mediator across subgroups (all s range = <0.001-0.005) except from the Hong Kong sample ( = 0.06) and the North and South American sample ( = 0.53). No mediation was found for problem-solving (except from the Northern European sample, = 0.009). Prosociality was the significant mediator in the Hong Kong sample ( = 0.016) and the Eastern European sample ( = 0.008). These findings indicate that fostering psychological flexibility may help to mitigate the adverse mental impacts of COVID-19 across regions. Roles of seeking social support, problem-solving and prosociality vary across regions.

Reliability and validity of the Turkish version of the Barriers to Nurses' Use of Physical Assessment scale.

Int J Nurs Pract 2021 Apr 23:e12935. Epub 2021 Apr 23.

Department of Fundamentals of Nursing, Florence Nightingale Nursing Faculty, Istanbul University-Cerrahpaşa, Istanbul, Turkey.

Aim: This study aimed to translate the Barriers to Nurses' Use of Physical Assessment Scale into Turkish and assess the new version's validity and reliability.

Methods: This was a methodological study to verify the linguistic equivalence of the scale through the translation/back-translation method. Twelve experts in health assessment confirmed the scale's content validity. Along with the Barriers to Nurses' Use of Physical Assessment Scale, an information form, including socio-demographic features, was distributed to 380 nurses, who consented to participate in the research. Data were collected between July 2017 and April 2018. Internal consistency, factor analysis and test-retest reliability were used to determine consistency over time and intraclass correlations.

Results: The content validity index of the scale (0.963) was calculated following confirmation of its language equivalence. With the confirmatory factor analysis, it was determined that the fit index values were at an acceptable level and the model was suitable. The factor analysis clustered factors in seven domains. The overall internal consistency coefficient was 0.822. All subscales and the overall scale showed high intraclass correlations.

Conclusion: The Turkish version of the Barriers to Nurses' Use of Physical Assessment Scale is a valid and reliable instrument.

Summary Statement: What is already known about this topic? Nursing assessment is a critical step in the nursing process. A holistic and systematic approach is key to improving the quality of nursing care, which may be hindered by barriers to the performance of physical assessment. Several international studies have examined the barriers encountered by nurses; however, there is a lack of both instruments and research on this subject in Turkish literature. What this paper adds? The findings confirmed that the Turkish version of the Barriers to Nurses' Use of Physical Assessment Scale is a valid and reliable instrument and can be used to determine the barriers to nurses' ability to perform physical assessments. Nurses and clinic managers will be able to use the scale to identify the factors preventing assessment and develop strategies to overcome them. The questionnaire can help eliminate assessment barriers to create an effective and systematic assessment environment. The implications of this paper: Nurses and clinical managers should work together to identify and eliminate assessment barriers. Barriers to nurses' use of physical assessments can be objectively identified through a valid and reliable tool, providing opportunities for the elimination of such barriers and the development of nursing assessment activities.

The Predictive Value of First-trimester Thiol/Disulfide Homeostasis in Preeclampsia.

J Coll Physicians Surg Pak 2021 Apr;30(4):405-409

Department of Obstetrics and Gynecology, Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkey.

Objective: To investigate the efficacy of first-trimester thiol/disulfide homeostasis (t/dh), a new oxidative stress marker, in predicting preeclampsia.

Study Design: Prospective cohort study.

Place And Duration Of Study: Department of Obstetrics and Gynecology, University of Health Sciences, Zeynep Kamil Women and Children Diseases Training and Research Hospital, Istanbul, Turkey, Department of Obstetrics and Gynecology, Bursa Yüksek Ihtisas Training and Research Hospital, Bursa, Turkey, from March 2016 to February 2019.

Methodology: In this multi-centre,serum samples of women with839 singleton pregnancies were collected between 11+0 to 13+6gestational weeks. A total of 215 singleton pregnant women were included in the study. The patient group consisted of 38 women, who were diagnosed with preeclampsia; while the control group consisted of 177 healthy pregnant women without any complication during pregnancy and after delivery. Totalthiol (TT) was estimated by the sum of existing thiol groups and reduced thiol groups (S-S and -SH). After the native thiols (-SH) and (TT) were determined, the disulfide (-SS) amounts, disulfide/total thiol percent ratios (-SS/-SH + -SS), disulfide/native thiol percent ratios (-SS/-SH), and native thiol/total thiol percent ratios (-SH/-SH + -SS) were calculated.

Results: There were no statistically significant differences between the groups in terms of[(-SH), (TT), (-SS), (-SS/-SH), (-SS/-SH + -SS), and (-SH/-SH + -SS)] six t/dh variables(p>0.05).The first-trimester body mass index (BMI) was statistically different between the two groups (p<0.001). In the receiver operating characteristic curve analysis, none of the concentrations of thiol levels and ratios was found to have a significant predictive value for preeclampsia. The BMI was a significant predictor for preeclampsia (area under curve: 0.749, p<0.001).

Conclusion: Maternal serum t/dh at 11+0 to 13+6 weeks of gestation does not predict preeclampsia and t/dh may be the consequence rather than a cause in the pathogenesis of preeclampsia. Key Words: First-trimester, Preeclampsia, Sulfhydrylcompounds, Thiols.

Diffusion-weighted imaging for the differentiation of Ewing sarcoma from osteosarcoma.

Skeletal Radiol 2021 Apr 2. Epub 2021 Apr 2.

Department of Radiology, Hacettepe University School of Medicine, 06100, Ankara, Turkey.

Objective: The purpose of this study is to assess the ability of apparent diffusion coefficient (ADC) values in differentiating Ewing sarcoma and osteosarcoma.

Materials And Methods: This retrospective cross-sectional observational study included a total of 35 patients with a recent diagnosis of Ewing sarcoma (n = 13) and osteosarcoma (n = 22) who underwent conventional MRI and diffusion-weighted imaging (DWI). Three ADC measurements from the areas of the lowest diffusivity in ADC maps (ADC), and other areas with low diffusivity (ADC), were made independently by two observers on pre-treatment MRI, and the means of these measurements were compared using independent samples t-test. Intraclass correlation coefficient was calculated for inter-observer agreement.

Results: There was a significant difference between the ADC (P < 0.001) and ADC (P < 0.001) in Ewing sarcoma and osteosarcoma for both observers. For Ewing sarcoma and osteosarcoma, mean ADC was 0.566 ± 0.07 and 1.193 ± 0.33 × 10 mm/s; 0.551 ± 0.08 and 1.182 ± 0.33 × 10 mm/s; and mean ADC was 0.813 ± 0.11 and 1.510 ± 0.35 × 10 mm/s; 0811 ± 0.12 and 1.501 ± 0.33 × 10 mm/s for observers 1 and 2, respectively. Inter-observer correlation coefficient for mean ADC was 0.994 and for mean ADC was 0.995.

Conclusion: Diffusion-weighted imaging and ADC values could be used in the differentiation of Ewing sarcoma and osteosarcoma in borderline cases.
