Purpose: This study investigated the influence of uncertainty in illness and coping on the quality of life (QoL) of colorectal cancer patients. Methods: Research involved 160 colorectal cancer patients receiving chemotherapy at a single tertiary hospital. Data collected between August 3 and October 8, 2020, were analyzed using t-tests, ANOVA, Pearson correlation, and multiple regression analysis with SPSS/WIN 25.0. Results: Results revealed low scores for ‘global health status’ but moderate scores for ‘function scale’ and ‘symptom scale.’ Uncertainty in illness exhibited a negative correlation, while coping correlated positively with QoL. Coping (β=.52, p<.001) and uncertainty in illness (β=-.26, p<.001) significantly influenced ‘global health status.’ Coping (β=.42, p<.001), uncertainty in illness (β=-.17, p=.021), and side effect symptoms (yes) (β=-.16, p=.022) were influencing factors in ‘function scale,’ and coping (β=-.33, p<.001) and side effect symptoms (yes) (β=.22, p=.002) were influencing factors for ‘symptom scale.’ Conclusion The findings underscore the importance of enhancing coping skills and reducing uncertainty in illness to improve QoL among colorectal cancer patients receiving chemotherapy. Consequently, nursing interventions assessing and managing uncertainty in illness, empowering positive coping strategies, and effectively managing side effect symptoms are imperative for enhancing the QoL of colorectal cancer patients.

BACKGROUND: Because the sternomental distance (SMD) is evaluated in conscience patients and in the sitting position, this could change under general anesthesia, which is a state that the patient is unconscious and fully relaxed in the supine position. Increasing age also affects the SMD. We investigated the change in the SMD with the patients under general anesthesia and we also investigated the effect of age on the SMD. METHODS: A total of 108 patients were allocated to Group Y (20-30 yr), Group M (31-50 yr) and Group O (51-70 yr). The SMD, as measured when the patients were awake and sitting, was defined as baseline. The SMD was measured in the supine position, the shoulder-suppressed supine position, at the time of loss of consciousness (LOC), 4 min after vecuronium administration and in the sniffing position. The percent change of the SMD (%) was defined as (the baseline SMD - the measured SMD)/the baseline SMD x 100. RESULTS: Compared with the baseline, the SMD decreased significantly in the supine position, the shoulder-suppressed supine position, at the time of LOC, during neuromuscular blockade and in the sniffing position in all the groups. Group O showed a shorter SMD than did Groups Y and M for all the measurements. There was no significant difference in the percent change of the SMD between the groups. CONCLUSIONS: This study demonstrated that the SMD was significantly reduced by the supine position, the sniffing position, at the time of loss of consciousness and during neuromuscular blockade with the patient under general anesthesia and also with the increasing age of the patient.

BACKGROUND: Gabapentin decreases acute nociceptive pain in animal and human studies when given before surgical incision. Various doses of gabapentin have been used (300-1,200 mg) to measure this preemptive effect. Here, we evaluated the optimal dose of gabapentin for reducing fentanyl consumption and the adverse effects of gabapentin following gynecologic surgery. METHODS: We recruited 100 patients who underwent laparotomy for gynecologic surgery. Patients were randomly divided into 4 groups and received a placebo (control), gabapentin 300 mg (G 300), gabapentin 600 mg (G 600), or gabapentin 1,200 mg (G 1200) 2 h before surgery. Postoperatively, patients received fentanyl via an intravenous patient controlled analgesia device. The cumulative fentanyl doses were recorded 2, 6, 12, 24 h, and 48 h postoperatively, and the sedation scale was recorded in the post anesthetic care unit (PACU). RESULTS: The postoperative fentanyl requirement was lower with gabapentin treatment, but there was no significant differences for the different doses. PACU sedation scores were not different in any group. CONCLUSIONS: Gabapentin has a preemptive effect in gynecologic surgery, but there were no additional fentanyl-sparing benefits at doses above 300 mg. Thus, 300 mg is an optimal dose for decreasing fentanyl consumption following gynecologic surgery.

BACKGROUND: Preoxygenation with tidal volume breathing for 3 min is commonly used technique. An end tidal expiratory oxygen concentration greater than 90% is considerd to be adequate for preoxygenation. The aim of this study was to check the effects of preoxygenation on elderly patients through the comparison with young patients during the 3 min tidal volume breathing technique. METHODS: Sixty patients from ASA class I or II who were scheduled for elective orthopedic general surgery were divided into an elderly (>65 yr) group and a control (25-65 yr) group. Patients were instructed in the technique of preoxygenation. Preoxygenation was accomplished with an appropriately sized face mask connected to an anesthesia machine with 100% oxygen during 3 min with patients in both groups. Expired O2, CO2 concentration and oxygen saturation were recorded simultaneously for 3 min. RESULTS: The elderly group showed significantly lower end tidal oxygen concentration than the control group from 50 sec to the end of study (180 sec) with the 3 min tidal volume breathing technique (P < 0.05). In 180 sec, the control group had over 90% (91.5%) end tidal oxygen concentration, but in the elderly group end tidal oxygen concentration could not reach 90% (86.2%). In oxygen saturation, the elderly group showed a significantly lower level until 40 sec from the start of study, and then two groups showed a similar levels of oxygen saturation until the end of study. CONCLUSIONS: End tidal oxygen concentration did not reach 90% in 180 sec in the elderly group during preoxygenation with the 3 min tidal volume breathing technique.

BACKGROUND: Postoperative nausea and vomiting (PONV) commonly occur after general anesthesia, especially in women. In this study, we evaluated the antiemetic efficacy of propofol administered at the end of surgery in highly susceptible patients undergoing a laparoscopy-assisted vaginal hysterectomy. METHODS: A total of 107 women undergoing a laparoscopy-assisted vaginal hysterectomy under general anesthesia were enrolled for this prospective, double-blind, randomized study. Fifteen minutes before the end of surgery, all patients received 50 microg fentanyl and 1 of following 3 doses; 0.5 mg/kg of propofol (propofol 0.5 group), 1 mg/kg of propofol (propofol 1.0 group), and normal saline (control group). All patients received intravenous patient-controlled analgesia (PCA). Emergence time, a visual analog scale for pain and nausea, duration of postanesthesia care unit (PACU) stay, and frequency of antiemetic use were recorded at 0-2, 2-24, and 24-48 hours postoperatively. RESULTS: The incidence of nausea significantly lower in the propofol 0.5 and propofol 1.0 groups than in the control group (12.1 vs 14.7 vs 40%). During the first postoperative 2 hours, antiemetics were less frequently administered in the propofol 0.5 and propofol 1.0 groups than in the control group (3.0 vs 5.9 vs 22.5%). Emergence time was slightly longer in the propofol 0.5 and propofol 1.0 groups than in the control group, but there was no significant difference in PACU stay time was observed between the 3 groups. CONCLUSIONS: The results of this study suggest that low-dose propofol administration at the end of surgery may effectively reduce the incidence of PONV within 2 hours postoperatively in highly susceptible women undergoing a laparoscopiy-assisted vaginal hysterectomy and receiving opioid-based PCA.

BACKGROUND: Intravenous administration of rocuronium induces intense pain in most patients (60-100%). This could be harmful during anesthesia induction because of the unintended reflex movement of an unconscious patient in response to the pain. Previous studies have reported that remifentanil effectively reduces rocuronium-induced pain and withdrawal movements. This study was designed to evaluate the EC50 and EC95 of remifentanil to prevent withdrawal movements in children. METHODS: We enrolled a total of 171 pediatric patients scheduled for general anesthesia in this study. Remifentanil was administrated by target-controlled infusion. Effect-site target concentrations ranged from 0.5 to 3.0 ng/ml. At each concentration, experiments were repeated in 10-20 patients. Propofol 2 mg/kg and rocuronium 0.9 mg/kg were administrated after equilibration of plasma and effect-site target remifentanil concentration. The withdrawal movements were graded on a 4-point scale. The EC50 and EC95 of remifentanil to prevent rocuronium-induced withdrawal movements were determined by using a logistic regression model. RESULTS: The logistic regression model showed that the probability of preventing rocuronium-induced withdrawal movement was as follows: exp (-3.49 + 2.07 x remifentanil concentration) / (1 + exp [-3.49 + 2.07 x remifentanil concentration]). EC50 and EC95 were 1.69 ng/ml (95% confidence intervals [CIs], 1.42-1.87) and 3.11 ng/ml (95% CIs, 2.79-3.72), respectively. CONCLUSIONS: Administration of remifentanil at an effect-site target concentration of 3.1 ng/ml could effectively prevent rocuronium-induced withdrawal movements.

BACKGROUND: The increasing number of dementia patients is increasing the importance of identifying them and also those at a high risk of dementia. The early diagnosis and management of dementia can slow the progression of the disease and reduce the socioeconomic burden. For these purposes, the Local Dementia Centers established in all regions of Korea are working on the early detection of dementia using neuropsychological batteries. This study investigated the utility of the Seoul Neuropsychological Screening Battery-Core (SNSB-C) in a dementia management project performed in the local community. METHODS: This study was conducted in two parts. The first part used data from the Local Dementia Centers to investigate the accuracy of detecting cognitive impairment in SNSB-C compared with the Seoul Neuropsychological Screening Battery-Second Edition (SNSB-II). The second part of this study which data from hospital examined the accuracy of diagnosing dementia using SNSB-C. RESULTS: Data were collected from 508 participants at the Local Dementia Centers in Daejeon and 50 participants at a hospital. SNSB-C had a high sensitivity and specificity for detecting cognitive impairment, and also a high sensitivity, high specificity, and positive predictive value for diagnosing dementia. CONCLUSIONS: The sensitivity in diagnosing dementia was as high for SNSB-C as for SNSB-II while taking less time. SNSB-C could therefore be a good diagnostic evaluation tool for use in local dementia centers.

BACKGROUND: This study compared the preventive effects of ramosetron and ondansetron on postoperative nausea and vomiting (PONV) in highly susceptible patients undergoing abdominal hysterectomy. METHODS: In a prospective, randomized, double-blinded study, a total of 120 highly susceptible women (nonsmokers, those receiving opioid-based IV patient-controlled analgesia [PCA]) undergoing abdominal hysterectomy were included in the study. Patients were divided into 2 groups and each group received either 0.3 mg of ramosetron or 4 mg of ondansetron, IV. All patients received fentanyl-based IV PCA during the 48 h postoperative periods. The incidences of PONV and side effects of 5-HT3 antagonists (headache and dizziness) were assessed at 3 intervals (<2 h, 2-24 h and 24-48 h) postoperatively. RESULTS: Patients in the ramosetron group showed a significantly higher ratio of complete response and lower incidence of nausea during the 24-48 h interval after surgery compared with those the ondansetron group. CONCLUSIONS: Ramosetron (0.3 mg) is more effective in preventing delayed PONV in highly susceptible women undergoing abdominal hysterectomy compared with ondansetron (4 mg).

Tuberculosis (TB) is a known occupational risk to health workers. Identifying risk factors in health care settings is critical to the prevention of TB for health workers and patients. In 2014, we carried out a TB screening and survey for 902 health workers from 14 selected military hospitals to determine the prevalence rate of latent tuberculosis infection (LTBI) as well as occupational risk factors. Of all subjects, 19.5% reported having provided TB patient care for 1 year or more (176/902), and 26.9% (243/902) were positive for the tuberculin skin test (TST) (10 mm or more of induration). Additionally, 21.4% (52/243) of those who tested positive were also positive for the interferon-gamma release assay (IGRA). The proportion of LTBI in the study population was 5.8% (52/902). In a multivariate logistic regression analysis, providing TB patient care for one year or more was the only significant occupational risk factor (adjusted odds ratio [aOR], 2.27; 95% confidence interval [CI], 1.13–4.56). This study suggests that military health workers working with TB patients should be regularly examined by chest radiography, TST and IGRA to detect LTBI in the early stage and control nosocomial infection of TB.
