ABSTRACT

Objectives@#This study was conducted to identify the level of mental health and burnout of medical staff at hospitals and public health centers, which responded to the coronavirus disease 2019 (COVID-19) in South Korea and to suggest appropriate management plans. @*Methods@#The mental health and burnout levels of medical staff responding to COVID-19 were evaluated through an online survey conducted during the period July 1–14, 2021. To analyze the mental health status of the participants according to their demographic characteristics, the chisquare test, t-test, and an analysis of variance were conducted, followed by Scheffe post-hoc tests for pairwise comparisons. @*Results@#A total of 773 participants were included in the study. An analysis of the clinically significant symptoms of the group showed that 29.5% had posttraumatic stress symptoms, 30.6% had depression, 15.8% had anxiety, 39.8% had somatic symptoms, and 4.5% were seen to be at risk of suicide. The average scores for burnout were as follows: 3.55±1.75 for emotional exhaustion, 2.68±1.73 for depersonalization, and 3.89±1.40 for personal accomplishment. Mental health problems and burnout were found to be high in women, those in the 20–39-year age bracket, those with less than 5 years of work experience, and public health center workers. @*Conclusion@#The medical staff responding to COVID-19 were observed to experience high levels of mental health and burnout problems. Work-related characteristics, such as younger age, lower work experience, and employment at a public health center, may have a negative impact on mental health and cause burnout. Therefore, individualized and systemic support for mental health and to prevent the burnout of medical staff responding to cases of COVID-19 is needed.

ABSTRACT

Background@#Several parameters are useful for assessing disease severity in idiopathic pulmonary fibrosis (IPF); however, the role of 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) is not well-defined. We aimed to evaluate the value of 18 F-FDG PET/CT for assessing disease severity and prognosis in IPF patients. @*Methods@#Clinical data of 89 IPF patients (mean age: 68.1 years, male: 94%) who underwent18 F-FDG PET/CT for evaluation of lung nodules or cancer staging were retrospectively reviewed. Mean and maximal standardized uptake values (SUV mean , SUV max , respectively) were measured in the fibrotic area. Adjusted SUV, including SUV ratio (SUVR, defined as SUV max -to-liver SUV mean ratio), tissue fraction-corrected SUV mean (SUV meanTF ), and SUVR (SUVRTF ), and tissue-to-blood ratio (SUV max /SUV mean venous; TBR blood ) were obtained. Death was defined as the primary outcome, and associations between other clinical parameters (lung function, exercise capacity, C-reactive protein [CRP] level) were also investigated. @*Results@#All SUV parameters were inversely correlated with the forced vital capacity, diffusing capacity for carbon monoxide, and positively correlated with CRP level and the gender-agephysiology index. The SUV mean , SUV max , and SUV meanTF were associated with changes in lung function at six months. The SUVR (hazard ratio [HR], 1.738; 95% confidence interval [CI], 1.011–2.991), SUVR TF (HR, 1.441; 95% CI, 1.000–2.098), and TBR blood (HR, 1.377; 95% CI, 1.038–1.827) were significant predictors for mortality in patients with IPF in the univariate analysis, but not in the multivariate analysis. @*Conclusion@#18 F-FDG PET/CT may provide additional information on the disease severity and prognosis in IPF patients, and the SUVR may be superior to other SUV parameters.

ABSTRACT

BACKGROUND AND OBJECTIVES: Levothyroxine (L-T4) monotherapy to normalize TSH level might be not sufficient to restore serum free triiodothyronine (fT3) levels in hypothyroid patients. This study aimed to compare the thyroid hormone levels in euthyroid L-T4 treated athyreotic patients and euthyroid healthy control subjects. MATERIALS AND METHODS: We included 69 euthyroid L-T4 treated athyreotic female patients after total thyroidectomy and radioactive iodine ablation therapy and 90 euthyroid healthy female. Serum fT3 and free thyroxine (fT4) levels were simultaneously measured using two different assay kits (A and B). RESULTS: The serum fT4 level was higher in the athyreotic patients (kit A: p<0.001, kit B: p=0.046), and the serum fT3 level was higher in control subjects (kit A: p=0.047, kit B: p=0.102). In the control group, the serum fT3 level was stable and not correlated with the TSH level (kit A: tau=−0.10, p=0.18, kit B: tau=−0.06, p=0.40). However, in the patient group, the serum fT3 level was negatively correlated with the TSH level (kit A: tau=−0.22, p=0.012, kit B: tau=−0.31, p<0.001). All thyroid hormone parameters measured by kit A showed higher area under the curve values than those measured by kit B for distinguishing the patients from the control subjects. CONCLUSION: The serum fT3 levels in L-T4 treated athyreotic euthyroid patients were significantly lower than and varied from those of euthyroid healthy control subjects. Thus, L-T4 monotherapy might not be appropriate for some athyreotic patients to maintain optimal T3 levels.

ABSTRACT

For the purpose of evaluating the effect of both direct retainer design and bony absorption degree around abutment of indirect retainer on the supporting tissue of abutment of indirect retainer, dislodging force was transmitted to unilateral distal extension RPD bases. Analysis of stress distributed within the supporting tissue around abutment of indirect retainer was carried out. Using three-dimensional photoelastic stress analysis method and the conclusion is a follows. 1. According to the extent of force which the direct retainer of the most distal abutment tooth, the amount of force transmitted to the abutment tooth of indirect retainer was small. 2. Of all the cases, Mandibular first premolar which was used abutment tooth of indirect retainer, buccal, mesial and distal sides represented compression stress and lingual side represented tensile stress. 3. The more bone resorption of abutment tooth of indirect retainer, the more distortion of buccal and distal side of abutment tooth was existed and the extent of compression stress which was existed and distal side to abutment tooth was large. 4. When the alveolar bone around the abutment with indircet retainer is normal. The amount of force transmitted on abutment with indirect retainer was small in the order of Akers clasp, RPA clasp, RPI clasp. 5. When the alveolar bone around the abutment with indirect retainer has been absorbed 20% and 30%, the amount of force transmitted on abutment with indirect retainer was small in the order of RPA calsp, RPI clasp, Akers clasp. 6. When denture is displaced, shape of the direct retainer reciprocating abutment affect much the function of indirect retainer.

ABSTRACT

Acrodysostosis is a rare multiple congenital malformation syndrome with peripheral dysostosis, nasal hypoplasia, mental retardation and growth failure. In 1968, Maroteaux and Malamut first described this disorder in three patients, and thus far now over 30 published cases have been reported worldwide. Radiographic changes include severe shortening of metacarpals, metatarsals, and phalages, cone-shaped epiphyses of the hands and feet, premature fusion of the epiphyses, and advanced bone age. Most patients do relatively well except for the problems of mental deficiency and arthritic complaints. Progressive restriction of movement of the hands, elbows, and spine may occur. Recently, we experienced a case of acrodysostosis in and 11-year-old boy who presented with short stature, short hands and feet, nasal hypoplasia, mental retardation, and typical radiographic findings including severe shortening of metacarpals, metatarsals and phalanges, cone-shaped epiphyses of the hands and feet.

ABSTRACT

PURPOSE: This study was done to see whether neonates born to unmarried mothers have higher rates of prematurity, low birth weight, perinatal morbidity and mortality than normal married group. METHODS: 88 neonates of unmarried mothers who were admitted in our NICU during the 5-year period from January 1987 through December 1991 were evaluated, and as the control group served 276 neonates of married mothers in 12 randomly selected weeks extended over the year during the same period. In statistical analyses, all data were analyzed by x2 test, Student t-test, and regression equation. RESULTS: 1) Unmarried mothers were 19.9+/-2.5(SD) year-old, with the majority(64.8%) falling into to age group between 16 and 20 years, whereas the control group was significantly older with 28.8+/-3.9 years. 2) Sex ratio was 1.38 : 1, with male prepondering, mean gestational age 35.5+/-3.7 weeks and mean birth weight 2,240+/-640g, in the unmarried group, differing significantly from the control group with 38.5+/-37 weeks and 2,910+/-750g. 3) Incidences of prematurity and low birth weight (LBW) were 70.5% and 75.0%, and total mortality was 28.4%. These values were significantly higher than in the control group, with 22.5%, 32.2%, 7.2%, respectively, and prematurity and LBW rate were also significantly higher in both groups of the same maternal age. Birth weight of unmarried group was significantly lower than control group in the same gestational age. Gestational age, birth weight, mortality rate were not significantly correlated to maternal age in both unmarried and control groups. 4) For the neonates of unmarried mothers, the majority was delivered either by midwife or in local obstetric clinics, and most of them(57.9%) were delivered by induction. 5) Neonatal diseases were jaundice, respiratory distress syndrome(RDS) and infection in the decreasing order, and incidence of RDS was significantly higher than in control group. But the death rate of RDS only tended to be higher in the unmarried-group. CONCLUSIONS: The neonates born to unmarried mothers have significantly higher rates of prematurity, LBW and mortality, and lower birth weight than the control group in the same gestational age. For neonatal diseases, incidence of RDS was significantly higher, and its mortality was significantly higher in the unmarried-group. Awareness on the seriousness of the problems leading to preventive measures against juvenile and unmarried child births, along with improved managements of babies born to unmarried mothers are urgently advocated.
