The incidence of hypotension in parturients with coronavirus disease (COVID-19) undergoing regional anesthesia remains controversial. This study aimed to investigate the incidence of hypotension during spinal anesthesia in parturients infected with COVID-19, as well as to identify associated risk factors. Methods: This retrospective study compared COVID-19-positive parturients who underwent cesarean section under spinal anesthesia (COVID-19 group) with a control group between January 2017 and June 2022. We reviewed the medical records and collected the following information: basic patient characteristics, spinal anesthesia, and newborn-related data. Results: Compared with the control group, the COVID-19 group did not show any significant differences in terms of hypotension occurrence and vasopressor usage. A positive correlation was noted in the COVID-19 group between heart rate and duration of hospital stay (P < 0.001, Spearman’s rho = 0.422). In subgroup analysis of the COVID-19 group, group with a baseline heart rate ≥ 100 (group H) had lower Apgar scores at 1 min, longer hospital stays, and more severe COVID-19 symptoms than the with a baseline heart rate < 100 (group L). Moreover, in group H, there was a positive correlation between the heart rate and the lowest systolic blood pressure after spinal anesthesia (P = 0.012, Spearman’s rho = 0.528). Conclusions: Parturients with COVID-19 do not appear to have a higher risk of hypotension during cesarean section under spinal anesthesia than those without COVID-19. Given the close association between preoperative heart rate and extent of hypotension in parturients with COVID-19 undergoing spinal anesthesia, vigilant monitoring of vital signs by anesthesiologists is crucial during the perioperative period.

We aimed to investigate the impact of the coronavirus disease 2019 (COVID-19) pandemic on admissions of patients with acute myocardial infarction, stroke, and severe trauma, and their excess mortality in emergency departments (EDs) in South Korea using registry data from the National Emergency Department Information System (NEDIS) for patients attending EDs of regional and local emergency medical centers. During the outbreak period of 2020, there were 350,698 ED visits, which was lower than the total in 2019 (392,627 visits).Multiple logistic regression revealed that, compared with 2019, there was significantly higher ED mortality rate during the COVID-19 outbreak in 2020 (adjusted odds ratio, 1.10;95% confidence interval, 1.07–1.13). This finding implies that during the early outbreak period, people might have avoided seeking medical care even for acute and life-threatening conditions, or transfer times at the scene to the hospital arrival were delayed, or treatment for the patients in EDs were delayed.

Purpose: To identify changes in medical expenditures and health care utilization before and after visual impairment onset, then analyze differences according to visual impairment severity. Methods: Patients aged ≥ 18 years who were registered as visually disabled from 2005 to 2013 were selected using the database from the registry of the disabled and the National Health Insurance Service. The observation period of 3 years before and after the registration was divided into 6-month units (12 points of interest). At each point of interest, medical cost, number of outpatient visits, and length of hospital stay (LOS) were analyzed. The control group was obtained through 1:10 stratification randomization to match sex and age; individuals in the control group were then selected via 1:1 propensity score matching for the premium quantile and residential area. Results: In total, 131,434 patients with visual disability and the same number of non-visually impaired controls were included. Compared with non-disabled individuals, the mean medical cost and number of outpatient visits were higher for patients with visual disability (1.9- and 1.4-fold, respectively, p < 0.001); the LOS was also 3.5 days longer (p < 0.001). The mean medical cost and number of outpatient visits were greater in severely visually disabled patients than in mildly disabled patients (1.6- and 0.5-fold, respectively, p < 0.001); the LOS was also 12 days longer in severely disabled patients (p < 0.001). From 18 months before disability registration, medical costs and LOS increased according to the presence and severity of visual disability; the number of outpatient visits increased uniformly, regardless of disability and severity. Conclusions More severe cases of visual impairment are associated with greater health care utilization and expenditures. Policy intervention is necessary to ensure that patients receive appropriate treatment and steady health care by reducing the burden of medical expenditures.

The aim of this study was to investigate the usefulness of a clinical screening test [the Korean Infant and Child Developmental Test (KICDT)] compared to language specific tests: the sequenced language scale for infant (SELSI) and the Preschool Receptive-Expressive language Scale (PRES) in children with delayed language development. A retrospective chart review was conducted on 615 children who visited the Department of Pediatrics at Chonbuk National University Hospital from January 2013 to December 2016. All patients were evaluated with KICDT as a clinical screening test and SELSI or PRES as a language specific test. Language Developmental Quotients (LDQs) from the KICDT were compared with the Receptive Language Quotient (RLQ) and expressive language quotient (ELQ) from the SELSI or PRES. The sensitivity, specificity and predictive values of LDQ of KICDT were calculated by comparing with SELSI/PRES. Language DQs from the KICDT were significantly correlated with the RLQ (r=0.706), ELQ (r=0.768), and total language quotient (TLQ) (r=0.766) from the SELSI/PRES (p<0.05). In cross tabulation, the patients belonging to the retardation groups in both KICDT and SELSI/PRES were 417 (67.8%). Otherwise, patients belonging to the normal group in KICDT but not in SELSI/PRES were 151 (24.6%). Sensitivity and specificity of LDQ of KICDT relative to SELSI/PRES were 72.3% and 92.2% respectively (p<0.05). Our data suggests that clinical screening tests alone, not cumbersome language specific tests, can determine language developmental delays in children.

PURPOSE: This study investigates the effect of pregnant women's growth mindset on the stress of pregnancy through ego-resilience. METHODS: The subjects included 551 pregnant women in Seoul and Gyeonggi area. Data were collected using a structured questionnaire; statistical, frequency, correlation, and structural equation analyses were performed using SPSS21 and M-plus 7.0. RESULTS: First, pregnant women's growth mindset had a direct effect on pregnancy stress. Second, the mediating pathway that influenced pregnancy stress through the ego-resilience of growth mindset was significant. CONCLUSION: These results suggest that it is important to devise and practice a method to improve the growth mindset of pregnant women, enhance ego-resilience, and reduce the negative effects of stress by reducing pregnancy stress.

PRF001 is a fragmented DNA polymer extracted from the testes of salmon. The purpose of this study was to assess the anti-inflammatory effect of PRF001 in vitro as well as the protective effect of PRF001 intake against arthritis in a rat model. In vitro, cell survival and inflammatory markers after H₂O₂ treatment to induce cell damage were investigated in CHON-001 cells treated with different concentrations of PRF001. In vivo, osteoarthritis was induced by intra-articular injection of monosodium iodoacetate (MIA) into the knee joints of rats. After consumption of PRF001 (10, 50, or 100 mg/kg) for 4 weeks, inflammatory mediators and cytokines in articular cartilage were investigated. In vitro, the levels of inflammatory markers, IL-1β, TNF-α, COX-2, iNOS, and PGE2, were significantly suppressed by PRF001 treatment. In vivo, the inflammatory mediators and cytokines, IL-1β, p-Erk1/2, NF-κB, TNF-α, COX-2, and PGE2, as well as MMP3 and MMP7, which have catabolic activity in chondrocytes, were decreased in the MIA-induced osteoarthritic rats following intake of PRF001. Histological analysis revealed that PRF001 had a protective effect on the articular cartilage. Altogether, these results demonstrated that the anti-inflammatory property of PRF001 contributes to its protective effects in osteoarthritis through deregulating IL-1β, TNF-α, and subsequent signals, such as p-Erk1/2, NF-κB, COX-2, PGE2, and MMPs.
