PURPOSE: The purpose of this study was to find the factors affecting the decisional conflict of patients undergoing chemotherapy.METHODS: Participants were 137 patients undergoing chemotherapy in a hospital. The Quality Quantity Questionnaire, a distress thermometer and the Decisional Conflict Scale were used to gather self-reported data. The collected data were analyzed using descriptive statistics, t-tests, ANOVA, post-hoc Scheffe's tests, Pearson's correlations coefficients and stepwise multiple regression.RESULTS: The decisional conflict showed that the score for severe to high distress groups were higher than that of the mild distress group. The levels of distress and satisfaction of chemotherapy decisional conflict were positively correlated (p=.043). Decisional conflict was significantly affected by age (p=.041), the burden of treatment costs (p=.047), the support system(p=.049), the current feeling of health(p=.024), and comorbidity (p=.039). The significant predictors of decisional conflict were support system, current feeling of health, age, and the burden of treatment costs, which explained 15% of the variance.CONCLUSION: To improve the decisional conflict patients who are receiving chemotherapy, it is deemed to be necessary to develop an intervention program, for oncology nurses to use regarding decisional conflict over cancer treatment in consideration of the variables we have identified.

PURPOSE: This study was conducted to identify the level of oxaliplatin-induced peripheral neuropathy (OIPN), symptoms, distress, and quality of life (QoL) in gastrointestinal (GI) cancer patients and to identify the factors influencing QoL.METHODS: A total of 123 patients were recruited for this cross-sectional study. Surveys used were the Therapy-Induced Neuropathy Assessment Scale (TNAS) for OIPN, the MD Anderson Symptom Inventory (MDASI-GI) for general symptoms associated with gastrointestinal cancer and its treatment, a distress thermometer, and the Euro Quality of Life Questionnaire 5-Dimensional Classification (EQ-5D) for QoL.RESULTS: The patients were classified into three groups based on their treatment completion time (current, completed less than one year ago, completed more than one year ago). The scores of MDASI-GI and distress were significantly lower in patients who had completed chemotherapy compared to those who were undergoing treatment (p=.04 and .02 respectively). However, TNAS score was significantly higher in patients who completed chemotherapy less than one year ago than the other two groups (p=.001). In multivariate regression models, the OIPN and distress or general symptoms were identified as factors associated with QoL.CONCLUSION: In this study, we identified the symptoms that are factors related to the QoL in patients with GI cancer. In particular, the symptoms of OIPN are reported at significantly increased levels for patients who have finished chemotherapy less than one year ago, so efforts to prevent and manage the symptoms of OIPN are needed in this timeframe. To improve QoL of patients with GI cancer, continuous attention and care are required not only during the treatment of cancer but also after the completion of treatment.

OBJECTIVES: It was the aim of this study to evaluate the effect of cooling water temperature on the temperature changes in the pulp chamber and at the handpiece head during high-speed tooth preparation using an electric handpiece. MATERIALS AND METHODS: Twenty-eight intact human molars received a standardized occlusal preparation for 60 seconds using a diamond bur in an electric handpiece, and one of four treatments were applied that varied in the temperature of cooling water applied (control, with no cooling water, 10°C, 23°C, and 35°C). The temperature changes in the pulp chamber and at the handpiece head were recorded using K-type thermocouples connected to a digital thermometer. RESULTS: The average temperature changes within the pulp chamber and at the handpiece head during preparation increased substantially when no cooling water was applied (6.8°C and 11.0°C, respectively), but decreased significantly when cooling water was added. The most substantial drop in temperature occurred with 10°C water (−16.3°C and −10.2ºC), but reductions were also seen at 23°C (−8.6°C and −4.9°C). With 35°C cooling water, temperatures increased slightly, but still remained lower than the no cooling water group (1.6°C and 6.7ºC). CONCLUSIONS: The temperature changes in the pulp chamber and at the handpiece head were above harmful thresholds when tooth preparation was performed without cooling water. However, cooling water of all temperatures prevented harmful critical temperature changes even though water at 35°C raised temperatures slightly above baseline.

Psychological distress is common in lung cancer patients with a poor prognosis. The present study aims to investigate the efficacy of collaborative care for patients with newly diagnosed inoperable lung cancer in South Korea. The study is a three-arm parallel-groups non-randomized clinical trial with an active arm that includes distressed patients who receive collaborative care, one comparison arm that includes distressed patients who receive enhanced usual care, and another comparison arm that includes non-distressed patients. In total, 267 consecutive patients newly diagnosed with medically inoperative lung cancer will be recruited. The primary outcomes are the changes in Hospital Anxiety and Depression Scale-depression and the Distress Thermometer at 12 and 32 weeks after enrollment. Sub-analyses of patients in the active arm of the study will include a comparison of the efficacy of a combination of oral antidepressant (escitalopram) treatment and collaborative care versus that of collaborative care alone.

This article reviews the historical development and up-to-date state of thermometric technologies for measuring human body temperature (BT) from two aspects: measurement methodology and signifi cance interpretation. Since the fi rst systematic and comprehensive study on BT and its relation to human diseases was conducted by Wunderlich in the late 19th century, BT has served as one of the most fundamental vital signs for clinical diagnosis and daily healthcare. The physiological implication of BT set point and thermoregulatory mechanisms are briefl y outlined. Infl uential determinants of BT measurement are investigated thoroughly. Three types of BT measurement, i.e., core body temperature, surface body temperature and basal body temperature, are categorized according to its measurement position and activity level. With the comparison of temperature measurement in industrial fi elds, specialties in technological and biological aspects in BT measurement are mentioned. Methodologies used in BT measurement are grouped into instrumental methods and mathematical methods. Instrumental methods utilize results of BT measurements directly from temperature-sensitive transducers and electronic instrumentations by the combination of actual and predictive measurement, invasive and noninvasive measurement. Mathematical methods use several numerical models, such as multiple regression model, autoregressive model, thermoregulatory mechanism-based model and the Kalman fi lter-based method to estimate BT indirectly from some relevant vital signs and environmental factors. Thermometry modalities are summarized on the dichotomies into invasive and noninvasive, contact and noncontact, direct and indirect, free and restrained, 1-D and n-D. Comprehensive interpretation of BT has an equal importance as the measurement of BT. Two modes to apply BT are classifi ed into real-time applications and long-term applications. With rapid advancement in IoT infrastructure, big data analytics and AI platforms, prospects for future development in thermometry and interpretation of BT are discussed.

PURPOSE: This study compared the temporal artery temperature (TAT) measured by infrared temporal artery thermometers to the axillary temperature (AT) measured by standard mercury-in-glass thermometers, and evaluated accuracy of the TAT measurement for clinical practice. METHODS: A total of 247 adult inpatients in general wards in a tertiary medical center located in Seoul participated in the study. The TAT was measured within one minute after the AT measurement. Data were analyzed using descriptive statistics, paired t-test, Pearson correlation coefficient, linear regression, and the Bland-Altman plot. RESULTS: There was a significant difference in mean temperature between AT and TAT, 36.89℃ (SD=0.70) versus 37.35℃ (SD=0.72). The Bland-Altman plots demonstrated the difference between the AT and TAT as −1.29 to +0.33. The specificity and sensitivity of the TAT in detecting fever were high. The positive predictive values were 57.5% and 71.0% when the AT were higher than 38.0℃ and the TAT fever cutoff levels were 38.0℃ and 38.3℃ respectively. CONCLUSION: TAT and AT were highly correlated and agreeable, indicating that TAT is as accurate as AT. The findings suggested that TAT measurement can be used in clinical practice. For accurate communication between medical personnel, medical institutions need to provide guidelines for temperature measurement, especially for the use of thermometer and measurement sites.

OBJECTIVES: Increasing use of medical devices outside of healthcare facilities inevitably requires connectivity and interoperability between medical devices and healthcare information systems. To this end, standards have been developed and used to provide interoperability between personal health devices (PHDs) and external systems. ISO/IEEE 11073 standards and IHE PCD-01 standard messages have been used the most in the exchange of observation data of health devices. Recently, transmitting observation data using the HL7 FHIR standard has been devised in the name of DoF (Devices on FHIR) and adopted very fast. We compare and analyze these standards and suggest that which standard will work best at the different environments of device usage. METHODS: We generated each message/resource of the three standards for observed vital signs from blood pressure monitor and thermometer. Then, the size, the contents, and the exchange processes of these messages are compared and analyzed. RESULTS: ISO/IEEE 11073 standard message has the smallest data size, but it has no ability to contain the key information, patient information. On the other hand, PCD-01 messages and FHIR standards have the fields for patient information. HL7 DoF standards provide reusing of information unit known as resource, and it is relatively easy to parse DoF messages since it uses widely known XML and JSON. CONCLUSIONS: ISO/IEEE 11073 standards are suitable for devices having very small computing power. IHE PCD-01 and HL7 DoF messages can be used for the devices that need to be connected to hospital information systems that require patient information. When information reuse is frequent, DoF is advantageous over PCD-01.

OBJECTIVE: The purpose of this study was to measure the temperature of the plugger tip of 3 cordless heat carriers set at 200°C. MATERIALS AND METHODS: Pluggers of the same taper (0.06, 0.08, 0.10) and similar tip sizes (sizes of 50 and 55) from 3 cordless heat carriers, namely SuperEndo-α2 (B & L Biotech), Friendo (DXM), and Dia-Pen (Diadent), were used and an electric heat carrier, System B (SybronEndo), was used as the control. The plugger tips were covered with customized copper sleeves, heated for 10 seconds, and the temperature was recorded with a computerized measurement system attached to a K-type thermometer at room temperature (n = 10). The data were analyzed with 2-way analysis of variance at a 5% level of significance. RESULTS: The peak temperature of the plugger tips was significantly affected by the plugger taper and by the heat carrier brand (p < 0.05). The peak temperature of the plugger tips was between 177°C and 325°C. The temperature peaked at 207°C–231°C for the 0.06 taper pluggers, 195°C–313°C for the 0.08 taper pluggers, and 177°C–325°C for the 0.10 taper pluggers. Only 5 of the 12 plugger tips showed a temperature of 200°C ± 10°C. The time required to reach the highest temperature or 200°C ± 10°C was at least 4 seconds. CONCLUSION: When using cordless heat carriers, clinicians should pay attention to the temperature setting and to the activation time needed to reach the intended temperature of the pluggers.

OBJECTIVES: This study aimed to identify the group with high risk of suicide in general hospital inpatient by comparing the depression, anxiety, and distress and their clinical characteristics. METHODS: The study included all patients admitted to a general hospital between January 2016 and December 2017, and the final 41,249 patients were analyzed. Distress thermometer (DT) and hospital anxiety-depression scale (HADS) were used for emotional state evaluation. Group with high risk of suicide was defined as showing more than 4 in the DT and more than 8 in one of the two subscales (anxiety and depression) of the HADS. RESULTS: Among the subjects, 3,603 patients (8.7%) met the high-risk criteria for suicide. The group with high risk of suicide experienced more severe pain than the control patient group, and it was found that there was more underlying disease. Patients who reported pain showed higher scores than those who reported no pain on the DT and HADS subscales. CONCLUSIONS: Group with high risk of suicide showed more severe pain and more underlying disease. Therefore, suicide prevention program specifically targeted for the group with high risk of suicide should be developed according to the risk of the patient evaluated at the time of the admission.
