BACKGROUND: The immune system is controlled by a complex network of regulatory mechanisms which include neurologic and psychological factors. Previous studies of psychopathological population and population challenged by significant life events have shown that high levels of anxiety and depression are associated with impaired cellular immunity. However, less is known about the psychoimmuological relevance of family function with the immune function In healthy population. The aim of the present study was to investigate the presence and direction of relationship between family function and cellular immunity. METHODS: Design : Cross sectional, observational study. Participants : 41 healthy adult males from a family medicine ambulatory care unit in a tertiary hospital completed a series of psychometric instruments that include the Family APGAR(Adaptation, Partnership, Growth, Affection, and Resolve), FACES III. In parallel, lymphocyte subset assay, lymphocyte proliferative responses to the mitogen concanavalin(ConA), interleukin 1-beta, interleukin-2 was analysed to assess cell-mediated immune function. RESULTS: Family adaptability was inversely correlated with total T cell, B cell counts, helper T cell(T,) and Iymphocyte proliferative response to low dose mitogen Con A(p<0.05). Family cohesion was inversely correlated with suppressor T cell(Ta) (p<0.05). In the lymphocyete proliferative response to low dose Con A stimulation, the extreme family showed the highest response compared to mid-range and healthy family(p<0.05). Relative to moderately dysfucntional family, severe dysfucntional family and healthy family had significantly higher lymphocyte proliferative responses to the high dose Con A(p<0.05). CONCLUSIONS: We suggest that family function could be related with immune function and it may impact on health and susceptibility to illness in helathy adult males. Further studies are required to elucidate the direction of relationship of family function and cellular immunity and the psychosocial mechanisms involved in the immune system.

PURPOSE: This study was done to investigate nurses' knowledge of, and compliance with the multidrug-resistant organism (MDRO) infection control guidelines. METHODS: A survey questionnaire was developed based on the institutional and national guidelines and was administered to a convenience sample of 306 nurses in a university hospital. RESULTS: The mean score for knowledge was 33.87 (percentage of correct answers: 82.61%). The percentages of correct answers for basic concepts, route of transmission, hand washing/protective devices and environment management were 74.27%, 94.29%, 92.90% and 75.54% respectively. The mean compliance score was 4.15 (range: 1-5). The compliance scores for education, communication, contact precaution, disinfection, surveillance culture, and hand washing were 3.29, 4.05, 4.20, 4.50, 4.40 and 4.48 respectively. Nurses indicated "lack of time (30.06%)", "lack of means (10.78%)" and "lack of knowledge (9.48%)" as reasons for noncompliance. CONCLUSION: While most educational programs have focused on hand washing or use of protective devices to prevent transmission of MDRO in acute care settings, hospital nurses' knowledge of the basic concepts of MDRO and environmental management has remained insufficient. Nurses are relatively non-compliant to the guidelines in the areas of education (staff, patient, family) and communication. Comprehensive educational programs are needed to decrease hospital infection rates and to improve the health of patients.

Redox-regulating molecule, recombinant human thioredoxin (rhTRX) which shows anti-inflammatory, and anti-oxidative effects against lipopolysaccharide (LPS)-stimulated inflammation and regulate protein expression levels. LPS-induced reactive oxygen intermediates (ROI) and NO production were inhibited by exogenous rhTRX. We identified up/downregulated intracellular proteins under the LPS-treated condition in exogenous rhTRX-treated A375 cells compared with non-LPS-treated cells via 2-DE proteomic analysis. Also, we quantitatively measured cytokines of in vivo mouse inflammation models using cytometry bead array. Exogenous rhTRX inhibited LPS-stimulated production of ROI and NO levels. TIP47 and ATP synthase may influence the inflammation-related lipid accumulation by affecting lipid metabolism. The modulation of skin redox environments during inflammation is most likely to prevent alterations in lipid metabolism through upregulation of TIP47 and ATP synthase and downregulation of inflammatory cytokines. Our results demonstrate that exogenous rhTRX has anti-inflammatory properties and intracellular regulatory activity in vivo and in vitro. Monitoring of LPS-stimulated pro-inflammatory conditions treated with rhTRX in A375 cells could be useful for diagnosis and follow-up of inflammation reduction related with candidate proteins. These results have a therapeutic role in skin inflammation therapy.

PURPOSE: The clinical efficacy of allergen-immunotherapy is known to be dose dependent. However, optimal maintenance dosage has not yet been determined for sublingual immunotherapy (SLIT). Furthermore, since companies adopt their own units for expression of allergenicity, the allergen concentrations of individual reagents cannot be compared easily. We sought to measure and compare the allergenicities of 3 commercially available house dust mite (HDM) SLIT regents and a subcutaneous immunotherapy reagent. METHODS: We measured the HDM allergenic potency of the maintenance dosages of three SLIT reagents: Staloral(R) (300 index of reactivity [IR] /mL, recommended maintenance dosage [MD]: 120 IR), SLITone(R) (1,000 standard therapeutic unit [STU]/mL, recommended MD: 200 STU), Wolwopharma(R) (100 microg/mL, recommended MD: 20 microg), and subcutaneous immunotherapy regents of Hollister-Stier (10,000 allergy unit [AU] /mL). The allergenic potency was assessed by measuring the total protein concentrations, mite group 1 and 2 allergens using 2-site ELISA, and an inhibition test against IgE specific to Dermatophagoides farinae and Dermatophagoides pteronyssinus. RESULTS: The protein content of the Wolwopharma(R) reagent was 1.5-261.4 times higher than that of the other 2 SLIT reagents. The concentration of group 1 major allergens in Staloral(R) (132.03 microg/mL) was 33- to 44.5-fold higher than in SLITone(R) (4.00 microg/mL) and Wolwopharma(R) (2.97 microg/mL). The concentration of group 2 major allergen was also 8.9- to 10.5-fold higher in Staloral(R) (15.7 microg/mL) than in SLITone(R) (1.8 microg/mL) or Wolwopharma(R) (1.5 microg/mL). An ELISA inhibition study against HDM-specific IgE showed that the allergen potency of Staloral(R) reagent is 8.5-fold and 21-fold higher than that of SLITone(R) or Wolwopharma(R), respectively. The differences between the maintenance dosages are further exaggerated by the differences in the recommended volumes of SLIT reagents. CONCLUSIONS: The allergen potencies of commercially available HDM SLIT reagents are markedly different. Consensus regarding the optimal allergen concentration for SLIT reagents used to treat HDM respiratory allergies is needed.

Background: The coronavirus disease 2019 (COVID-19) pandemic has caused significant changes. This study aimed to investigate the impact of COVID-19 on patients with chronic pain. Methods: Patients with chronic pain from 23 university hospitals in South Korea participated in this study. The anonymous survey questionnaire consisted of 25 questions regarding the following: demographic data, diagnosis, hospital visit frequency, exercise duration, time outside, sleep duration, weight change, nervousness and anxiety, depression, interest or pleasure, fatigue, daily life difficulties, and self-harm thoughts. Depression severity was evaluated using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was used to investigate the relationship between increased pain and patient factors. Results: A total of 914 patients completed the survey, 35.9% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. The pain level of 200 patients has worsened since the COVID-19 outbreak, which was more prominent in complex regional pain syndrome (CRPS). Noticeable post-COVID-19 changes such as exercise duration, time spent outside, sleep patterns, mood, and weight affected patients with chronic pain. Depression severity was more significant in patients with CRPS. The total PHQ-9 average score of patients with CRPS was 15.5, corresponding to major depressive orders. The patients’ decreased exercise duration, decreased sleep duration, and increased depression were significantly associated with increased pain. Conclusions COVID-19 has caused several changes in patients with chronic pain.During the pandemic, decreased exercise and sleep duration and increased depression were associated with patients’ increasing pain.

Background: Complex regional pain syndrome (CRPS) is an intractable pain disease with various symptoms. Here, we investigated the disease status, work life, sleep problems, medical insurance, economic status, psychological problems, and quality of life (QOL) of CRPS patients. Methods: CRPS patients from 37 university hospitals in South Korea were surveyed.The survey questionnaire consisted of 24 questions on the following aspects of CRPS patients: sex, age, occupation, cause of injury, activities of daily living (ADL), pain severity, sleep disturbance, level of education, economic status, therapeutic effect, and suicidal ideation. Additionally, the abbreviated World Health Organization Quality of Life (WHOQOL-BREF) questionnaire, consisting of 26 questions, was used to identify the status of QOL. Results: A total of 251 patients completed the questionnaire. According to the survey, 54.2% patients could not perform ADL on their own. Over the previous week, the mean pain score was 7.15 ± 1.78 (out of a total of 10 points); 92.1% of patients had sleep disorders and 80.5% had suicidal ideation, with most patients suffering from psychological problems. The average for each domain of WHOQOL-BREF was as follows: 21.74 ± 14.77 for physical, 25.22 ± 17.66 for psychological, 32.02 ± 22.36 for social relationship, and 30.69 ± 15.83 for environmental (out of a total of 100 points each). Occupation, ADL, sleep time, therapeutic effect, and suicidal ideation were statistically correlated with multiple domains. Conclusions Most patients had moderate to severe pain, economic problems, limitations of their ADL, sleep problems, psychological problems, and a low QOL score.

Background: Use of opioids for chronic intractable pain is increasing globally, and their proper use can improve patients’ quality of life. In contrast, opioid use disorders, such as abuse or addiction, caused by prescribing opioids, are a worldwide issue. This study aimed to understand current opioid prescribing patterns and pain physicians’ experiences with opioid use in South Korea. Methods: Pain physicians in 42 university hospitals in South Korea were asked to complete anonymous questionnaires regarding opioid prescriptions. Results: A total of 69 surveys were completed. Most pain physicians started prescribing opioids at a pain score of 7/10 and aimed to reduce pain by 50%. Most physicians (73.1%) actively explained the prescribed medications and possible side effects, and 61.2% of physicians preferred the prescription interval of 4 weeks.Immediate-release opioids were the most popular treatment for breakthrough pain (92.6%). The most common side effect encountered by physicians was constipation (43.3%), followed by nausea/vomiting (34.3%). Of the physicians, 56.5% replied that addiction and misuse prevalences were less than 5%. However, the most concerning side effect was addiction (33.0%). Conclusions The survey results showed that the prescribing patterns of pain physicians generally followed Korean guidelines. Physicians were most interested in the safety and effectiveness of opioid prescriptions. They were most concerned about respiratory depression and abuse or addiction. A significant number of physicians agreed that the NHIS regulations needed improvement for patient convenience and safe and effective treatment, though there were pros and cons of the NHIS restrictions on prescription conditions.
