Purpose: Due to the high incidence of shoulder injuries, including shoulder impingement syndrome (SIS), among CrossFit practitioners due to frequent overhead movements, serratus anterior exercises are considered crucial for scapular stabilization in both intervention and prevention. Objective: The objective of this study is to compare the muscle activity and ratios of scapular stabilizing and shoulder girdle muscles between individuals with and without SIS during serratus punch and wall slide exercises, both targeting the serratus anterior muscle, in CrossFit training practitioners. Methods: Surface electromyography was used to compare the muscle activity and activity ratio of scapular stabilizing muscles and shoulder muscles during serratus punch and wall slide exercises in two groups of 20 CrossFit practitioners: ten with SIS and ten without symptoms. Results: The group with SIS showed higher activation of the pectoralis major, upper trapezius, and a higher pectoralis major/serratus anterior and upper trapezius/serratus anterior muscle activation ratio during the serratus punch exercise compared to the group without SIS. Similarly, during the wall slide exercise, the group with SIS exhibited higher activation of the upper trapezius and a higher upper trapezius/serratus anterior muscle activation ratio compared to the group without SIS. However, no significant difference in serratus anterior muscle activation was observed between the two groups. Conclusions This study highlights the higher activation of the pectoralis major and upper trapezius muscles in CrossFit practitioners with SIS during the serratus anterior exercise, suggesting the importance of minimizing the overactivation of these muscles to prevent impingement syndrome in this population.

Background: The proportion of women doctors has been rising globally and South Korea mirrors this trend. Despite this growth, women doctors’ representation in leadership roles in academic medical fields remains scarce. This study investigates the representation and trends of women doctors’ leadership in editorial boards of South Korean medical journals, and compares the gender ratio of specialists. Methods: This non-clinical data analysis examined the editorial boards of 45 major medical academic journals published in 2015, 2020, and 2024 to investigate women leadership within journal editorial boards, compares the gender ratio of specialists, and observed changes over time. Results: The study included data from 1,475 members in 2015, 1,598 in 2020, and 2,531 in 2024.In 2020, 23.8% of specialists were women, but only 19.5% of editorial board members were women (P < 0.001). Nine journals had less than 10% women representation on their editorial boards. Over nine years, women representation on editorial boards increased from 16.8% in 2015 to 21.3% in 2024 (P = 0.001), with significant increases in societies of clinical medicine (14.6% vs. 20.0%; P < 0.001) but not in basic medicine. Journals with women editors-in-chief had significantly higher women representation on their boards compared to ones with male editorsin-chief (36.7 ± 13.5% vs. 18.4 ± 10.9%, P < 0.001). The proportion of women senior editorial roles and that of women executive society members showed a significant positive correlation with the proportion of women on editorial boards (P < 0.001 and P < 0.001, respectively). Conclusion The study highlights the considerable underrepresentation of women in editorial leadership compared to their presence as specialists. However, the number of women editorial board members has increased over the past decade, especially in clinical medicine. Women doctors’ leadership positively correlates with higher women participation on boards, which suggests that promoting women leaders could enhance gender diversity in academic medicine. Further qualitative research is needed to explore the impact of women doctors’ leadership on medical research and patient outcomes. This study provides critical insights into gender disparities in South Korean medical academia and underscores the need for policies to promote women doctors’ leadership.

PURPOSE: Fractional exhaled nitric oxide (FeNO) is considered an indirect marker of airway inflammation, and forced expiratory flow between 25% and 75% of vital capacity (FEF25%-75%) is widely used as a sensitive indicator of small airway obstruction in asthma. The aim of this study was to investigate relationships between FeNO and FEF25%-75% in children with asthma. METHODS: A total of 118 children with asthma underwent spirometry and measurement of eosinophil markers. FeNO levels were measured, and skin prick tests to 13 common allergens were done. Study subjects were divided into 2 groups according to FEF25%-75% values (group 1, normal FEF25%-75%> or =65%pred, n=90; group 2, impaired FEF25%-75%<65%pred, n=28). RESULTS: The mean (+/-standard deviation, SD) age was not significantly different between groups 1 and 2 (10.3+/-2.8 years vs. 11.1+/-3.4 years), and the sex ratio was also not significantly different between 2 groups. The geometric mean (range of 1 SD) concentration of FeNO was significantly higher in group 2 than in group 1 (25.8 ppb [14.2-46.9 ppb] vs. 37.2 ppb [24.2-57.2 ppb], P=0.008). A significant inverse correlation between FeNO and FEF25%-75% was observed in group 2 (r=-0.493, P=0.038), but not in group 1 (r=-0.037, P=0.749) after adjustment for confounders, such as atopy, age, sex, weight, and height. CONCLUSION: FeNO levels were higher in group of asthmatic children with impaired FEF25%-75% level. FeNO levels were inversely correlated with FEF 25%-75% only in impaired small-airway obstruction group after adjustment for atopy. These results suggest that small-airway obstruction may relate more closely to airway inflammation in asthmatic children with impaired small-airway function.

Congenital tuberculosis (TB) is a rare disease that is associated with high mortality. Mycobacterium tuberculosis, the causative agent, may be transmitted from the infected mother to the fetus by the transplacental route or by aspiration of infected amniotic fluid. Clinical symptoms and signs are not specific. Miliary patterns are the most common findings in the chest X-rays of many infants with congenital TB. In this case, an 18-day-old boy had jaundice on the fifth day of birth, and fever and respiratory distress appeared on the 18th day. Chest X-ray showed diffuse fine bilateral infiltration. Clinically, pneumonia or sepsis was suspected. Respiratory symptoms and chest X-ray findings worsened despite empirical antibiotic therapy. The lungs showed miliary infiltration suggestive of TB. Gastric aspirates were positive for M. tuberculosis. Respiratory distress and fever were gradually improved after anti-TB medication. Congenital TB is difficult to detect because of minimal or no symptoms during pregnancy and nonspecific symptoms in neonates. Hence, clinicians should suspect the possibility of TB infection even if neonates have non-specific symptoms. Early diagnosis and meticulous treatment are required for the survival of neonates with TB.

Intravenous infusion flow regulators (IIFRs) are widely used devices but it is unknown how much the difference between the IIFR scale and the actual flow rate depends on the viscosity of the intravenous (IV) fluid. This study evaluated the effects of viscosity on the flow rate of five IV fluids (0.9% normal saline, Hartmann’s solution, plasma solution-A, 6% hetastarch, and 5% albumin) when using IIFRs. The viscosity of crystalloids was 1.07–1.12 mPa·s, and the viscosities of 6% hetastarch and 5% albumin were 2.59 times and 1.74 times that of normal saline, respectively. When the IIFR scales were preset to 20, 100, and 250 mL/hr, crystalloids were delivered at the preset flow rate within a difference of less than 10%, while 6% hetastarch was delivered at approximately 40% of the preset flow rates and 5% albumin was approximately 80% transmitted. When delivering colloids, IIFRs should be used with caution.

Recently, computer-aided design and computer-aided manufacturing (CAD/CAM) environment have changed the clinician treatment method in the fabrication of prosthesis. The diagnostic wax-up by using digital technology simplifies the laboratory process and provides clinical efficiency and convenience. In this case, Digital diagnostic wax-up was superimposed on extra-oral photo to consider the patient’s facial appearance and utilized to produce the final prosthesis. It can be more efficient and esthetic than a diagnostic wax-up that was made only on a model. The digital diagnostic wax-up that superimposed on extra-oral photo not only visualizes the predicted outcome of prosthodontic treatment but also improves satisfaction and facilitates the communication between patient and dentist. We report aesthetically and functionally satisfactory results that obtained after restoration.
