Based on the literature study,the thoughts and possible therapeutic mechanism in treating male infertility from the perspective of spleen and kidney by regulating intestinal flora were explored.Disturbance of intestinal flora is one of the important factors leading to the development of male infertility,and the spleen and kidney have certain similarities to intestinal flora in the physiological function and pathological changes.Moreover,tonifying the kidney and strengthening the spleen can regulate the intestinal flora by fostering the growth of beneficial bacteria,inhibiting the reproduction of pathogenic bacteria,and protecting the barrier of the intestinal mucosa.Therefore,the possible therapeutic mechanisms in treating male infertility with the prescriptions for tonifying the kidney and strengthening the spleen to regulate intestinal flora are as follows:inhibiting the expression of inflammatory factors to reduce the inflammatory reaction of testicular tissues;improving the antioxidant capacity to alleviate the damage of spermatozoa caused by oxidative stress,and improving the bad mood to alleviate the impact of psychological stress on the reproductive system.The exploration of the thoughts for treating male infertility from the perspective of spleen and kidney by regulating intestinal flora may provide a new entry point for modern Chinese medicine clinical treatment of male infertility.

Purpose@#We aimed to analyze the occurrence of lymphedema as a side effect in patients who underwent regional nodal irradiation (RNI) following surgery for breast cancer. @*Methods@#This retrospective study was conducted on patients with breast cancer who underwent surgery from July 2014 to October 2020 at Inje University Busan Paik Hospital. The analysis included 113 cT1-3N1-3M0 breast cancer patients who underwent RNI as part of radiotherapy (RT). Mostly, surgeries were performed using breast-conserving surgery (n = 99, 87.6%), except for 14 patients with modified radical mastectomy. The total RT dose for RNI was 45–60 Gy, and the fraction size was 1.8–2.0 Gy. Most patients underwent chemotherapy (n = 98, 86.7%), including taxanes (n = 92, 81.4%). @*Results@#The median follow-up was 61.1 months (range, 5.0–110.5 months). Lymphedema occurred in 54 patients (47.8%) after surgery. Twenty of them (17.7%) developed a new onset of lymphedema after RT, while 34 (30.1%) detected lymphedema before the completion of RT. Over the follow-up, 16 patients (14.2%) experienced recurrence. High radiation dose (>50.4 Gy) for RNI (P = 0.003) and taxane use (P = 0.038) were related to lymphedema occurrence after RT. Moreover, lymphedema occurrence after RT was also related to recurrence after surgical resection (P = 0.026). Breast-conserving surgery was related to early-onset lymphedema before the completion of RT (P = 0.047). Furthermore, the degree of lymph node dissection (≤4) was related to the overall occurrence of lymphedema (P = 0.045). @*Conclusion@#Considering a reduction in RNI dose may be beneficial in mitigating the incidence of lymphedema after RT in patients with breast cancer.

Background@#Aging leads to sarcopenia, which is characterized by reduced muscle mass and strength. Many factors, including altered muscle protein turnover, diminished neuromuscular function, hormonal changes, systemic inflammation, and the structure and composition of muscle fibers, play a crucial role in age-related muscle decline. This study explored differences in muscle fiber types contributing to overall muscle function decline in aging, focusing on individuals with hip fractures from falls. @*Methods@#A pilot study at Chungnam National University Hospital collected muscle biopsies from hip fracture patients aged 20 to 80 undergoing surgical treatment. Muscle biopsies from the vastus lateralis and gluteus maximus were obtained during hip arthroplasty or internal fixation. Handgrip strength, calf and thigh circumference, and bone mineral density were evaluated in individuals with hip fractures from falls. We analyzed the relationships between each clinical characteristic and muscle fiber type. @*Results@#In total, 26 participants (mean age 67.9 years, 69.2% male) were included in this study. The prevalence of sarcopenia was 53.8%, and that of femoral and lumbar osteoporosis was 19.2% and 11.5%, respectively. Vastus lateralis analysis revealed an age-related decrease in type IIx fibers, a higher proportion of type IIa fibers in women, and an association between handgrip strength and type IIx fibers in men. The gluteus maximus showed no significant correlations with clinical parameters. @*Conclusion@#This study identified complex associations between age, sex, handgrip strength, and muscle fiber composition in hip fracture patients, offering insights crucial for targeted interventions combating age-related muscle decline and improving musculoskeletal health.

Purpose@#We present the case of a 4-month-old boy with a large orbital cyst that caused lateral displacement of the optic nerve resulting in progressive exophthalmos of the left eye since birth.Case summary: A 4-month-old boy presented with progressive exophthalmos of the left eye since birth. Physical examination revealed marked left eye proptosis. Magnetic resonance imaging revealed microphthalmia and a 2.2 × 1.9 cm orbital cyst in the retrobulbar region. Subsequently, an anterior orbitotomy of the left eye was performed to dissect and excise the cyst. Histopathological examination revealed an orbital cyst containing neuroectodermal tissue. No complications or recurrences were observed during the 3-month post-surgery period. @*Conclusions@#Congenital microphthalmia with orbital cysts is a rare condition that does not always require surgical intervention. However, timely surgical intervention in cases of severe exophthalmos can result in favorable functional and cosmetic outcomes. We present a case that exhibited significant improvement following surgical removal of the orbital cyst.

Purpose@#To report the long-term clinical outcomes of non-surgical treatment involving prosthetic eye wear in patients diagnosed with congenital microphthalmos. @*Methods@#A retrospective review of the medical records of 20 patients was conducted. In total, 21 eyes were diagnosed with congenital microphthalmos between May 2008 and December 2022 at Seoul St. Mary’s Hospital in Korea. @*Results@#This study included 20 patients (12 males and 8 females) with an average age of 4 months at diagnosis. The observed ophthalmic anomalies included two cases of congenital cataract, one of posterior embryotoxon, one of corneo-iris strand, four of iris coloboma, five of central corneal opacity, one of Peter's anomaly, and one of retrobulbar cyst. Accompanying systemic abnormalities were noted, such as lateral ventricle atrophy, corpus callosum atrophy, patent ductus arteriosus, atrial septal defect, and developmental language disorder. Genetic anomalies included anti SS-A/Ro antibody positivity, a 1:100 titer of anti-nuclear antibody, and a PAX6 mutation identified through next-generation sequencing. No specific family histories or pregnancy-related factors were noted. The average follow-up duration was 5.94 years (range: 1 month to 18 years), the average corneal diameter was 4.6 mm, the average axial length was 17.44 mm, the average age for first artificial eye trial was 5.96 years (range: 7 months to 19 years), and the average interval for artificial eye replacement was 22 months (range: 4 months to 5 years and 8 months). @*Conclusions@#Twenty patients with congenital microphthalmos underwent gradual expansion of their prosthetic eyes by regular replacement and size increase without severe complications. This approach led to aesthetically and emotionally positive outcomes for the patients.

Purpose@#To investigate the prevalence ratio of primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) in the Asian population. @*Methods@#Systematic searches of PubMed, Embase, and Cochrane databases for population-based studies in Asia published until August 5, 2022. We conducted a meta-analysis for PACG to POAG prevalence ratio using inverse variance–weighted random-effects meta-analyses so as to combine the study-specific measures of association. Between-study outcome variation (i.e., heterogeneity) was quantified with the I2 statistic. The multiple meta-regression analyses were performed in order to further account for the reasons for heterogeneity. @*Results@#Twenty studies, with a total study population of 52,522 individuals, had been conducted in 13 countries. The pooled PACG to POAG prevalence ratio was 2.204 (95% confidence interval, 1.617–3.004) with high heterogeneity (p < 0.001). In multiple meta-regression model, prevalence of POAG is the most important predictor for heterogeneity (model importance, 0.954), followed continent (0.508), and publication year (0.222). For every additional elevation of POAG prevalence (i.e., increase of 1.0%), the PACG to POAG prevalence ratio is expected to rise by 0.471. @*Conclusions@#We estimated the pooled PACG to POAG prevalence ratio in the Asian population. The POAG prevalence is the most important factor to determine the PACG to POAG prevalence ratio.

Objective@#The prolonged coronavirus disease-2019 (COVID-19) pandemic is likely to cause psychological distress in people. This systematic review aimed to identify the effectiveness of virtual reality (VR)-based psychological intervention among individuals with psychological distress during the COVID-19 crisis. PubMed, Ovid MEDLINE, Cochrane Library, Web of Science, Embase, and PsycINFO databases were searched for articles published until July 2022. @*Methods@#The available citations were deduplicated and screened by two authors using the title and abstract information. Eligibility criteria were constructed according to the PICOT guidelines. Empirical studies of all designs and comparator groups were included if they appraised the impact of an immersive VR intervention on any standardized measure indicative of psychological distress (stress, anxiety, depression, and post-traumatic symptoms) or improvements in quality of life in participants, including COVID-19 patients, medical staff working with COVID-19 patients, and people who had experienced strict social distancing during the COVID-19 pandemic. @*Results@#The results were discussed using a narrative synthesis because of the heterogeneity between studies. Seven of the studies met the inclusion criteria. There were two randomized controlled trials and five uncontrolled studies on VR interventions. @*Conclusion@#All studies reported significant improvement in a wide range of psychological distress during COVID-19, ranging from stress, anxiety, depression, and post-traumatic symptoms to quality of life, supporting the efficacy of VR-based psychological intervention. Our results suggest that VR intervention has potential to ameliorate COVID-19-related psychological distress with efficacy and safety.

This study aims to explore the effect of Buyang Huanwu Decoction glycosides on the inflammatory response of apolipoprotein E~(-/-)(ApoE~(-/-)) mice and RAW264.7 cells through nuclear factor kappa-B(NF-κB) signaling pathway. In the in vivo experiment, ApoE~(-/-) mice were fed with high-fat diets for 12 weeks to induce the animal model of atherosclerosis, and 75 μg·mL~(-1) oxidized low-density lipoprotein(Ox-LDL) incubated RAW264.7 cells for 24 h to establish the atherosclerosis cell model. Automatic biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay(ELISA), Western blot, and droplet digital polymerase chain reaction(PCR) were used to determine the blood lipid levels, aortic intimal thickness, inflammatory factor content, NF-κB pathway-related proteins, and mRNA expression levels, and evaluate arterial atherosclerotic lesions and anti-atherosclerotic mechanisms of the drug. The model of atherosclerosis was successfully established in ApoE~(-/-) mice after 12 weeks of feeding with high-fat diets. In the model group, the plasma levels of total cholesterol(TC), triglyceride(TG), and low-density lipoprotein cholesterol(LDL-C) were increased(P<0.01), the intima of the blood vessels was thickened, the levels of inflammatory factors tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) were increased, and the protein and mRNA expressions of NF-κB and inhibitor of NF-κB(IκBα) were significantly increased as compared with the control group. Compared with the model group, the high-dose Buyang Huanwu Decoction glycoside group decreased the plasma levels of TC, TG, and LDL-C, reduced the plaque area and thickness and the content of inflammatory factor TNF-α, and inhibited the protein and mRNA expressions of NF-κB and IκBα, with the effect same as Buyang Huanwu Decoction. In the in vivo experiment, 75 μg·mL~(-1) Ox-LDL stimulated RAW264.7 cells for 24 h to successfully establish a foam cell model. As compared with the control group, the nuclear amount of NF-κB and the protein and mRNA expressions of IκBα in the model group increased. Compared with the model group, the middle-dose and high-dose Buyang Huanwu Decoction glycoside groups decreased the nuclear amount of NF-κB and the protein and mRNA expressions of IκBα. The above results show that the glycosides are the main effective substances of Buyang Huanwu Decoction against atherosclerosis, which inhibit the NF-κB pathway and reduce the inflammatory response, thus playing the role against atherosclerotic inflammation same as Buyang Huanwu Decoction.

Objectives@#. Voice abuse in noisy environments can result in voice disorders. However, insufficient studies have sought to differentiate vocal cord lesions through laryngoscopic examinations among workers in noisy environments. This study investigated the relationship between a history of noise exposure in the workplace and benign vocal fold lesions (BVFLs). @*Methods@#. We used Korea National Health and Nutrition Examination Survey data from 2010 to 2012. The chi-square test was used to compare characteristics between two groups according to the presence or absence of BVFLs. To investigate the association between BVFLs and noise exposure in the workplace, we calculated adjusted odds ratios and 95% confidence intervals (CIs) using multiple logistic regression analysis. @*Results@#. In total, 10,170 participants with available laryngoscopy results were enrolled. Smoking history, hypertension, diabetes, and exposure to noise for more than 3 months at the workplace were significantly more common in participants with BVFLs. After adjusting for age, sex, smoking, drinking, obesity, hypertension, diabetes, income, education, and occupation as confounders, we confirmed that BVFLs were 1.52 times more likely (95% CI, 1.157–1.990) to occur in individuals with occupational noise exposure. @*Conclusion@#. Working in a noisy environment could induce BVFLs in workers through voice abuse. Social recognition that a noisy environment is a risk factor for BVFLs needs to be improved, and preventive measures should be implemented.

Squamous cell carcinoma in situ (SCCIS) is a precancerous lesion that usually appears as a well-demarcated erythematous scaly plaque, histopathologically characterized by atypical full-thickness disarrangement and pleomorphic atypical keratinocytes. Extramammary Paget disease (EMPD) is an intraepidermal tumor that usually affects skin in the genital region, histopathologically identified by large cells with pale and vacuolated cytoplasm, called Paget cells, in the epidermis. An 84-year-old female presented with an asymptomatic solitary scaly erythematous plaque on her back first noticed 10 years prior. A keratotic mass was noted immediately adjacent to the plaque. A biopsy was performed; one specimen showed atypical full-thickness disarrangement and pleomorphic keratinocytes with negative CK7 staining in the epidermis, and another specimen showed Paget cells above the basal layer with positive CK7 staining in the epidermis. Based on these findings, the patient was diagnosed with SCCIS coexisting with EMPD. The patient underwent wide surgical excision of the lesion with reconstruction, and is being monitored without recurrence.

Objective@#Menopause symptoms can vary in type, duration, and severity. The purpose of this study was to investigate the key factors predicting severe symptoms among Korean perimenopausal women with various demographic data, obstetric and psychiatric histories, and menopausal symptoms screening scale scores. @*Methods@#Data were collected from 1,060 women, and 4 latent classes were identified using latent profile analysis, with 6 major categories of menopausal complaints. Among the 4 classes, we selectively used data from the “all unimpaired” and “all impaired” groups. Menopause rating scale (MRS), sociodemographic, obstetric, and psychiatric factors were assessed, and hierarchical logistic regression analyses were conducted with the “all impaired” group as a dependent variable. @*Results@#Marital status and scores on the psychological and somatic subscales of the MRS were statistically related to being in the “all impaired” group. Otherwise, family history of menopausal symptoms, menarche age, and history of other psychiatric disorders were not statistically significant predictors of being in the “all impaired” group. @*Conclusion@#The psychological and somatic subscales of the MRS predict the severity of perimenopausal syndrome better than obstetric and psychiatric history do among Korean perimenopausal women. Psychological and somatic symptoms as well as genitourinary symptoms in menopausal patients should be closely evaluated.

Background and Objectives@#Sialendoscopy is useful for the diagnosis and treatment of obstructive salivary gland diseases, but not yet universally employed because it requires dedicate, expensive, and fragile endoscopic equipment; moreover, the surgical technique is also delicate. Here, we describe our initial experience of sialendoscopy, as well as the learning curve, precautions, and drawbacks that beginners must overcome in employing sialendoscopy.Subjects and Method The medical records of 98 patients who underwent sialendoscopic procedures at Eunpyeong St. Mary’s Hospital from May 2019 to March 2022 were retrospectively reviewed. The type of procedure, success rate, operation time, and complications were analyzed. @*Results@#We have performed a total of 85 sialendoscopic procedures, including 79 to treat submandibular sialolithiasis, two to treat submandibular ductal stenosis, two to treat parotid sialolithiasis, and two to treat parotid ductal stenosis. Of the total of 81 patients with sialolithiasis, 82.4% were treated by sialendoscopy only, 15.3% by hybrid procedure, and 2.3% opted to preserve the salivary gland and convert to external submandibular gland excision. Four patients with ductal stenosis were treated via endoscopic bougination; stents were placed for 4 weeks without any restenosis. The operation time was significantly shorter for the second half than for the first half of the patients (58.6 min vs. 39.8 min). Longer operation time was associated with the parotid gland diseases, larger stones (>5 mm in diameter), more proximal stones (from the salivary gland), and multiple stones. We encountered no major surgical complications. @*Conclusion@#Sialendoscopy is useful and safe; even beginners can evaluate and manage obstructive salivary gland diseases.

Background@#and Purpose Cognitive and behavioral changes are common in amyotrophic lateral sclerosis (ALS), with about 15% of patients presenting with overt frontotemporal dementia and 30%–50% with varying degrees of impairments. We aimed to develop and validate the Korean version of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS-K), a brief multidomain assessment tool developed for ALS patients with physical disability. @*Methods@#We developed the ECAS-K according to the translation guidelines, and administered it to 38 patients with ALS and 26 age- and education-level-matched controls. We also administered the Montreal Cognitive Assessment (MoCA) and Frontal Assessment Battery (FAB) to investigate convergent validity, and the Center for Neurologic Study-Liability Scale to assess the association between pseudobulbar affect and cognitive/behavioral changes. @*Results@#Internal consistency among the ECAS-K test items was found to be high, with a Cronbach’s alpha of 0.87. Significant differences were found between patients with ALS and the controls in language, fluency, and memory functions (p<0.05). Abnormal performance based on the ECAS total score was noted in 39.4% of patients, and 66.6% presented behavioral changes in at least one domain. Significant correlations were observed between the scores of the ECAS-K and those of other cognitive screening tools (MoCA and FAB, with correlation coefficients of 0.69 and 0.55, respectively; p<0.01). @*Conclusions@#We developed and validated the ECAS-K which could be used as an effective tool to screen the cognitive and behavioral impairments in Korean patients with ALS.

Objectives@#The purpose of this study was to compare the fracture strength and traslucency of 3D printing resin crowns according to different thicknesses. @*Methods@#Resin crowns were designed with CAD software and a 3D scanner, using scanned data of the #61 tooth model. Resin Crowns with different thicknesses were printed using a 3D printer, and subsequently divided into four groups according to thickness (0.3, 0.5, 0.7, and 1.0 mm). Fracture strength was compared among groups with a resin strip crown of 1.0 mm thickness. Compressive force was applied using a universal testing machine at 30° along the lingual surface at 1 mm/min cross head speed. For translucency evaluation, thin square specimens were printed of thicknesses 0.3, 0.5, 0.7, and 1.0 mm, and translucency was measured using a spectrophotometer. @*Results@#As a result of fracture strength measurement, fracture strength increased as thickness increased, and a significant difference was observed solely between thicknesses of 0.3 and 0.5 mm, and the thicknesses of 0.3 and 0.5 mm (P<0.05). Translucency decreased as thickness increased, and similarly, a significant difference was observed only between thicknesses of 0.3 and 0.5 mm and the thicknesses of 0.7 and 1.0 mm (P<0.05). @*Conclusions@#A 3D printing resin crown can be used as a clinical option for restoring a primary anterior tooth affected by caries.

Objective@#Providing inpatient nursing care inevitably involves night shift work. However, night shift work nurses often face psychiatric health problems such as burnout. If night shift work is an essential work type for nurses, it is necessary to select personnel suitable for night shift work or establish improvement measures such as psychiatric intervention through psychiatric evaluation. The objective of this study was to identify factors that could be interventional among factors affecting burnout in shift-working nurses. @*Methods@#A total of 231 night shift female nurses participated in this study. A questionnaire survey was given to assess their general characteristics. To assess burnout, the Maslach Burnout Inventory–General Survey Korean version was adopted. In addition, several mental health scales were used to identify individual psychological characteristics. To identify variables associated with the presence of burnout, odds ratios were calculated using a logistic regression model taking three dimensions of burnout as a dependent variable after adjusting for psychological and occupational factors. @*Results@#High resilience was a significant preventive factor in the three dimensions of burnout. Regarding occupational factor, the longer the duration of employment, the higher depersonalization, but the professional efficacy was good. @*Conclusion@#Our results indicate that resilience and social support could be prevention factors for burnout. This study is meaningful in examining items that require active intervention and support for burnout targeting night shift nurses who are indispensable for patient care.

Purpose@#This study aimed to identify the effect of warm scarf on xerostomia and sore throat in postoperative colon cancer patients. @*Methods@#A total of 40 participants with colon cancer who underwent colon cancer operation over 2hours were included from C University hospital in Seoul. The number of experimental group and control group is each 20 calculated by G*Power, and they were assigned by using nonequivalent control group no-synchronized design. In the experimental group, a warm scarf was applied to the neck for 120 minutes from entering the recovery room after the colorectal cancer surgery was completed. In the experimental group and the control group, xerostomia and sore throat were measured twice at 60-minute intervals. The degree of xerostomia was measured through the degree of wetness of the absorbent paper in mm, and the degree of sore throat was measured through the NRS (Numeral Rating Scale). Data were collected using self-administered questionnaires from August 2018 to September 2020 and were analyzed using IBM SPSS/WIN 21.0 Descriptive statistics, x2 test, Fisher's exact test, t-test were used to determine the participant's characteristics. The effect of warm scarf on xerostomia and sore throat were separately estimated by Repeated Measures ANOVA. @*Results@#The experimental group showed significant decrease of xerostomia and sore throat as time goes (p<.001). @*Conclusion@#Results indicate that warm scarf on xerostomia and sore throat in postoperative colon cancer patients is helpful method for relieving side effect of tracheal intubation.

Purpose@#To investigate the long-term efficacy of dacryoendoscopy-guided recanalization and silicone tube intubation in patients with obstruction in the lacrimal drainage system and to identify factors related to surgical outcome. @*Methods@#We retrospectively reviewed the medical records of patients with primary nasolacrimal duct obstruction and canalicular obstruction who underwent dacryoendoscopy-guided recanalization and silicone tube intubation between August 2014 and March 2016. Factors related to surgical outcome were examined and compared between the success group (eyes with complete response and partial response) and the failure group. Kaplan-Meier survival analysis and multivariable logistic regression analysis were used to analyze the success rate according to the factors found to have statistical significance. @*Results@#The study included 74 eyes of 51 patients. The mean age of the patients was 60.3 ± 10.0 years (range, 34–80 years). The success group consisted of 66 eyes (89.2%) (complete response, 56 eyes, 75.7%; partial response, 10 eyes, 13.5%) and the failure group consisted of eight eyes (10.8%). The median follow-up period was 58 months (range, 6.5–72 months), and the overall success rate was 89.2%. Compared to the eyes with preoperative lacrimal irrigation test of partial passage, the eyes with no passage were associated with a lower success rate (95.9% vs. 76.0%, p = 0.01). Postoperative inflammation was also associated with a lower success rate (96.6% vs. 60.0%, p < 0.001). @*Conclusions@#Dacryoendoscopy-guided recanalization and silicone tube intubation is effective and can be considered a first choice of treatment for eyes which show partial passage in the lacrimal irrigation test. The management of postoperative inflammation is essential to ensure surgical success.
