A teacher with self-efficacy is more able to accomplish any task from the management so that he is engaged to his work, and a teacher who regards his work as a calling has the proper motivation to work better. The aim of this study was to find whether there is a correlation between teacher’s self-efficacy and work engangement and whether there is a correlation between the meaning of work as a calling and work engagement of private high school teachers in Surabaya. The subjects (N = 87) were teachers from three private schools in Surabaya. The data was collected through close-ended statements scales with five options of answer that were later analyzed through a nonparametric correlation test with SPSS 19.00. The result showed a correlation between teachers’ self-efficacy and work engagement (r = .08; p < .05) and a correlation between the meaning of work as a calling and work engagement (r = .612; p < .05). Based on the result, it could be concluded that teachers’ self efficacy and meaning of work as a calling could not be treated as one unit, but each correlated independently with their work engagement.

One of the factors that influence compliance is individual motivation. There are still many pulmonary tuberculosis patients who do not wear masks, this can have an impact on disease transmission. Poor individual motivation can affect someone's compliance. The purpose of this research is to determine the relationship of patient motivation regarding prevention of transmission with adherence to the use of masks in patients with pulmonary tuberculosis in Rambipuji Health Center, Jember Regency. This research uses descriptive correlative type of research. In this study using a cross-sectional approach. The sample of this study was taken using simple random sampling, namely pulmonary tuberculosis patients at the Rambipuji Health Center in Jember Regency, totaling 105 patients but only 50 patients were used as samples. This research was conducted by giving a questionnaire to pulmonary tuberculosis patients to find out the patient's motivation about preventing transmission by adhering to the use of masks. The results of the study were analyzed using the Lambda Correlation Test, the results of the analysis found that the motivation of patients was good motivation (22%), patient motivation was sufficient (56%), and patient motivation was less motivation (22%). Whereas adherence to the use of masks in pulmonary tuberculosis patients is compliant (36%), and non-compliant (64%). The Lambda Correlation Test results obtained from the variable compliance with ρ = 0.389 positive direction with a value of ρ count of 0.027 <0.05 which means there is a relationship between patient motivation about prevention of transmission with compliance with the use of masks in patients with pulmonary tuberculosis in Rambipuji Health Center, Jember District. It is recommended that further studies be able to conduct more in-depth research related to the relationship of patient motivation regarding the prevention of transmission with adherence to the use of masks in pulmonary tuberculosis patients

Abstract Funding Acknowledgements Type of funding sources: None. Background. Many patients with COVID-19 suffer from arterial hypertension and have marked variations in blood pressure (BP) during the acute period of infection. The reasons for such changes are poorly understood. Purpose. To assess the relationship between the level of BP and the severity of changes in the main clinical and laboratory parameters in patients with arterial hypertension and with a moderate course of COVID-19 at the stage of the height of the disease. Materials and methods. The study included 86 hospitalized patients with verified coronavirus disease of moderate severity: 46 of them were male, the median age was 65 years. Patients received adequate hypertension therapy for a long time. After hospitalization, treatment was adjusted if necessary. The level of laboratory parameters in the acute period of the disease was determined, including the electrolytes, C-reactive protein (CRP), albumin, ferritin, general blood test, etc. BP measured daily. The relationship between laboratory parameters and BP level was evaluated by nonparametric correlation using the Spearman coefficient and multivariate analysis based on the "generalized nonlinear model". Results. In 67.44% of patients with hypertension, an elevated BP level (&gt;140/90) was observed against the background of moderate COVID-19. There was a significant negative correlation between the levels of CRP and BP throughout the stay in the hospital, the most significant is the 5th day of hospitalization. At the same time, a slightly stronger relationship is observed with diastolic BP (r = -0.4425) than with systolic BP (r = -0.3525). A similar trend is observed in all BP measurements. Besides, a negative correlation was found between potassium levels and BP values. The strongest association of potassium levels is with systolic BP on the day of hospitalization (r = -0.4850) and diastolic pressure on the 1st day of hospitalization (r = -0.3561). Multivariate analysis confirmed independent and reliable "influence" of CRP (p = 0.00018) and potassium (p = 0.03921) as independent predictors of diastolic pressure. Conclusions. Most patients with hypertension and moderate COVID-19 have elevated BP levels. There is a statistically significant negative relationship between the values of BP and levels of CRP and potassium. The obtained data may correspond to the existing hypothesis about the significant role of the kinin–kallikrein system in the pathogenesis of COVID-19.

Purpose To evaluate the changes in intraocular pressure (IOP), corneal thickness (CT), and retinal nerve fiber layer thickness (RNFLT) in patients with hypothyroidism before and after treatment. Methods A complete ophthalmic examination including visual acuity, IOP, anterior segment, and fundus examination together with CT and RNFLT measurements were performed for each patient with newly diagnosed hypothyroidism, at the initial diagnosis and the third and ninth months of the L-thyroxine treatment. Wilcoxon signed rank test and Spearman's correlation test were used for statistical evaluation of the results. Results A total of 56 eyes of 28 patients were included in the study. The mean IOP and CT values were found to decrease with medical treatment (p=0.000). There was no significant change in any of the RNFLT parameters measured with scanning laser Polarimeter after L-thyroxine treatment (Wilcoxon, p>0.05). The change in IOP levels was not correlated with the change in thyroid hormone levels (Spearman's correlation test, p>0.05). The mean increase in serum free T3 and serum free T4 levels and the mean decrease in serum TSH levels at the ninth month of the therapy were found to be correlated with the decrease in CT in the left eyes (Spearman's correlation test, R>0.4 and p<0.05). Conclusions Hypothyroidism seems to cause a reversible increase in CT and IOP. IOP changes may be secondary to CT changes. RNFLT parameters measured with scanning laser Polarimeter do not seem to be affected by hypothyroidism. When the CT is taken into account and the IOPs corrected for CT, the prevalence of glaucoma in hypothyroidism may not be as high as previously reported. This issue should be taken into account while assessing glaucoma in patients with hypothyroidism.

Background: While previous studies showed that oncology nurses were highly inclined to promote advance care planning (ACP), there is a limited study focusing on ACP that concerns the willingness to promote ACP among palliative nurses in Indonesia. This issue needs to be investigated to determine the causative factors so that interventions for nurses can be arranged to improve ACP in Indonesia.Purpose: This study aimed to identify predictors of the willingness to promote ACP among nurses in palliative care settings.Methods: This study used a descriptive-analytical design with a cross-sectional approach. A total of 150 registered nurses with at least one year of experience were purposively recruited. Data were collected using the Indonesian version of the willingness to promote ACP instrument (I-WPACP) with a possible score range of 24 to 120; the higher the score, the higher the willingness to promote ACP. The descriptive statistic, independent t-test, Pearson correlation test, Spearman rank correlation test, and multiple linear regression test were used to analyze the data.Results: The willingness to promote ACP showed a mean score of 84.73±9.36. The score indicates a high willingness to promote ACP. The experience of receiving palliative care education became a related factor as well as the most closely related factor to the willingness to promote ACP in the palliative care settings (β=0.184; p=0.028).Conclusion: The willingness to promote ACP among nurses is high and closely related to their experience of receiving education about palliative care. Education about palliative care and training on ACP needs to be developed so that nurses can discuss ACP with patients and family caregivers.

Background: Stress is one of the risk factors for cardiovascular disease and decreased heart rate variability is associated to increased mortality in some cardiac diseases. The aim of the study was to assess the impact of perceived stress on cardiac autonomic regulation in young healthy volunteers. Methods: 35 young healthy volunteers (19 to 29 years old, 6 men) from a Brazilian population were assessed for perceived stress by the translated and validated Perceived Stress Scale (PSS, 14 questions) and had the R-R intervals recorded at rest on supine position (POLAR RS800CX) and analyzed (5 minutes, Kubius HRV software) by Fast-Fourier Transform for quantification of Heart Rate Variability (HRV). Results: Average data (±SD) for age, heart rate, BMI, waist circumference and percentage of body fat (%BF) were: 21.3±2.7 years; 65.5±7.9 bpm; 22.3±1.9 Kg/m 2 ; 76.0±6.1 cm and 32.1±6.6%; respectively. The mean score for the PSS-14 was 23.5±7.2 and for the HRV parameter as follow: SSDN=54.8±21.2ms; rMSSD=55.9±32.2ms; low-frequency (LF)= 794.8±579.7ms 2 ; High-frequency (HF)= 1508.0±1783.0 ms 2 ; LF(n.u.)= 41.1±16.2; HF(n.u.)= 58.9±16.2; LF/HF=0.89±0.80 and Total power (TP)= 3151±2570ms 2 . Spearman nonparametric correlation was calculated and there was a significant correlation of PSS-14 scores and LF (ms 2 ) (r=−0.343; p= 0.044). Other HRV variables did not shown significant correlation but also had negative values for Spearman r (TP r=−0.265, p=0.124; HF r=−0.158; SSDN r=−0.207; rMSSD r=−0.243, p=0.160). LF/HF and LF(n.u.) did not correlate to PSS-14 having Spearman r very close to zero (LF/HF r=−0.007, p=0.969; LF(n.u.) r=−0.005, p=0.976). No correlation was found for HRV parameters and BMI and there was a trend for statistical correlation of %BF and LF (ms 2 ) (r=−0.309, p=0.071). Conclusions: These data demonstrate a possible association of perceived stress level and HRV at rest. Changes in LF can be a consequence of both sympathetic and parasympathetic activity, however, analyzing the other variables HF, TP, SSDN and rMSSD (all negative Spearman r) and due to the lack of changes in LF/HF ratio and LF(n.u.) we interpret that increased stress may be associated to decrease in overall heart rate variability. These changes were seen in healthy individuals and may point out an important mechanism in cardiovascular disease development.
