ABSTRACT

Background@#The ratio of estimated glomerular filtration rate (eGFR) based on cystatin C and creatinine (eGFRcystatin C/eGFRcreatinine ratio) is related to accumulating atherosclerosis-promoting proteins and increased mortality in several cohorts. @*Methods@#We assessed whether the eGFRcystatin C/eGFRcreatinine ratio is a predictor of arterial stiffness and sub-clinical atherosclerosis in type 2 diabetes mellitus (T2DM) patients, who were followed up during 2008 to 2016. GFR was estimated using an equation based on cystatin C and creatinine. @*Results@#A total of 860 patients were stratified according to their eGFRcystatin C/eGFRcreatinine ratio (i.e., 1.1). Intima-media thickness was comparable among the groups; however, presence of carotid plaque was frequent in the 1.1 group, 17.2%, P1.1 group, 1,494.0±252.2 cm/sec, P<0.001). On comparing the <0.9 group with the 0.9–1.1 group, the multivariate-adjusted odds ratios of prevalence of high baPWV and carotid plaque were 2.54 (P=0.007) and 1.95 (P=0.042), respectively. Cox regression analysis demonstrated near or over 3-fold higher risks of the prevalence of high baPWV and carotid plaque in the <0.9 group without chronic kidney disease (CKD). @*Conclusion@#We concluded that eGFRcystatin C/eGFRcreatinine ratio <0.9 was related to an increased risk of high baPWV and carotid plaque in T2DM patients, especially, those without CKD. Careful monitoring of cardiovascular disease is needed for T2DM patients with low eGFRcystatin C/eGFRcreatinine ratio.

ABSTRACT

Objectives@#. This study aimed to assess predictors of the response to varying durations of proton pump inhibitor (PPI) use and lifestyle modification treatment for laryngopharyngeal reflux disease (LPRD). @*Methods@#. Between October 2014 and June 2016, a prospective, multicenter, open-label, single-cohort, intention-to-treat, observational study was conducted at eight referral hospitals across the Republic of Korea to examine predictors of early and late response to treatment in adult patients (age ≥19 years) with LPRD. Participants underwent standard treatment (PPI [Esomezol] and lifestyle modification) for 3 months. Response to treatment was defined as greater than 50% improvement in reflux symptom index score. The primary outcome was potential predictors of treatment response at 1 and 3 months. The secondary outcome was potential predictors distinguishing early from late responders. @*Results@#. In total, 394 patients were enrolled. Improved sleep habits was a positive predictor (odds ratio [OR], 1.785; 95% confidence interval [CI], 1.06–3.007; P=0.029), while initial alcohol consumption (OR, 0.587; 95% CI, 0.355–0.969; P=0.037) and past medication history (OR, 0.438; 95% CI, 0.215–0.891; P=0.005) were negative predictors of response after 1 month of treatment. High pre-reflux finding score was a positive predictor (OR, 1.187; 95% CI, 1.049– 1.344; P=0.007), while male sex (OR, 0.516; 95% CI, 0.269–0.987; P=0.046), higher depression score (OR, 0.867; 95% CI, 0.784–0.958; P=0.005), and past thyroid hormone medication history (OR, 0.161; 95% CI, 0.033–0.788; P=0.024) were negative predictors of response after 3 months of treatment. Past medication history (OR, 0.438; 95% CI, 0.215–0.891; P=0.023) was the only negative predictor for early responders compared to late responders. @*Conclusion@#. Adult patients with LPRD and a history of prior medication use may require longer treatment durations to achieve a therapeutic response. Future research should explore the incorporation of diverse treatment approaches to improve treatment outcomes for patients exhibiting negative prognostic indicators.

ABSTRACT

AIM:To evaluate the correlation between axial lengths and anterior segment parameters using swept-source optical coherence tomography(SS-OCT).METHODS:For the cross-sectional clinical study, a total of 109 adult volunteers with different degrees of myopia recruited from January 1, 2022, to March 31, 2022, at the ophthalmology clinic of the First Affiliated Hospital of Zhengzhou University were included. Participants were divided into 4 groups based on axial length(AL): group A(AL≤24.0mm), group B(24.0mm&#x003C;AL≤25.0mm), group C(25.0mm&#x003C;AL≤26.0mm)and group D(AL&#x003E;26.0mm). Anterior segment examinations were performed using SS-OCT, including: central corneal thickness(CCT), lens thickness(LT), anterior chamber depth(ACD), anterior chamber width(ACW), angle opening distance(AOD500), angle recess area(ARA500), trabecular iris space area(TISA500), trabecular iris angle(TIA500), crystalline lens rise(CLR). The relationships between these data and AL, spherical equivalent(SE)were analyzed.RESULTS:There was no difference in the comparison of CCT among the four groups(P&#x003E;0.05). There were differences in SE, LT, ACD, ACW, AOD500, ARA500, TISA500, TIA500 and CLR among the four groups(all P&#x003C;0.01). SE and LT were negatively correlated with AL(r=-0.75, -0.41, all P&#x003C;0.01); ACD, ACW and CLR were positively correlated with AL(r=0.58, 0.45, 0.54, all P&#x003C;0.01); AOD500, ARA500, TISA500 and TIA500(temporal and nasal side)were positively correlated with AL(all P&#x003C;0.01). ACD and CLR were negatively correlated with SE(r=-0.21,-0.25, all P&#x003C;0.01), and LT was positively correlated with SE(r=0.21, P&#x003C;0.05).CONCLUSION:As AL increases, CCT remains unchanged while the ACD and ACW increase. The position of the crystalline lens moves backward and LT decreases.

ABSTRACT

Mosaic embryos contain two or more genetically distinct cell lines, which can be detected by pre-implantation genetic testing for aneuploidy. At present, it has been reported that mosaic embryo transfer can lead to healthy live births. In order to prevent severe adverse pregnancy outcomes, such as implantation failure, abortion, congenital malformation and neonatal death after implantation of mosaic embryos, it is critical to carry out genetic counseling, prenatal diagnosis and pregnancy supervision for mosaic embryo transfer. This article reviews the selection of mosaic embryos, the pregnancy outcomes of mosaic embryo transfer, and the safety of offspring, in order to provide references for the clinical practice of mosaic embryo transfer.

ABSTRACT

Objective@#Individuals with borderline personality disorder (BPD) commonly have a favorite person (FP), whom they are heavily emotionally attached to and dependent on. This study aims to identify and illustrate the patterns of destructive FP relationships based on actual experiences described by those with BPD. @*Methods@#A data mining process was conducted using raw data collected from online communities, such as blogs and social networks. An in-depth review of the information to better understand the natural course of the FP relationship was also conducted. @*Results@#Individuals with BPD form an intense and insecure attachment toward their FP, from which they enormously suffer. FPs can be their friends, romantic or life partners, or family members. As their feelings go beyond their control, being increasingly obsessed with their FP, they make their FP gradually lose hope in continuing the relationship and want to quit trying to fulfill their needs. The relationship finally ends when the FP stops being responsible for meeting their expectations and eventually drifts away. @*Conclusion@#This study suggests that certain FPs, distinctively named Teddy Bear Person, may behave in a particular manner to increase the likelihood of the FP relationship becoming more destructive. Moreover, the rejection sensitivity model should be discussed to understand their dysfunctional interaction.

ABSTRACT

Objectives@#To investigate the association between serum uric acid (UA) and relative hand grip strength (HGS) in comparison with metabolic syndrome components. @*Methods@#We analyzed the data of 5247 Korean adults aged ≥ 20 years (2422 men and 2825 women) who participated in the KNHNES VII (2018). @*Results@#Among women, relative HGS was significantly lower in participants with hyperuricemia (1.65 ± 0.04) than in those without (1.95 ± 0.01) and was significantly decreased in the highest quartile (4Q: 1.77 ± 0.02) of serum UA compared with that in the lowest quartile (1Q: 1.98 ± 0.02). Among men, relative HGS was lower in participants with hyperuricemia (3.09 ± 0.04 vs. 3.16 ± 0.02) and decreased in 4Q (3.08 ± 0.03) of serum UA compared with that in 1Q (3.15 ± 0.03); however, these results were not statistically significant. In age- and multivariate-adjusted analyses in men, relative HGS was significantly lower in 4Q compared with that in 1Q in model 1 (adjusted for age), but there were no significant differences in model 2 (adjusted for age, BMI, and waist circumference) and model 3 (adjusted for age, BMI, waist circumference, systolic and diastolic blood pressure, fasting blood glucose, triglycerides, and high-density lipoprotein cholesterol). Meanwhile, in women, relative HGS was significantly decreased in 4Q compared with that in 1Q in all models. @*Conclusions@#A significant inverse correlation was observed between serum UA levels and relative HGS in women, and their significance was maintained even after adjusting for age and metabolic syndrome components.

ABSTRACT

Background and Objectives@#Vocal fold (VF) scar is known to be the most common cause of dysphonia after laryngeal microsurgery (LMS). Steroids reduce postoperative scar formation by inhibiting inflammation and collagen deposition. However, the clinical evidence of whether steroids are helpful in reducing VF scar formation after LMS is still lacking. The purpose of this study is to determine whether intralesional VF steroid injection after LMS helps to reduce postoperative scar formation and voice quality.Materials and Method This study was conducted on 80 patients who underwent LMS for VF polyp, Reinke’s edema, and leukoplakia. Among them, 40 patients who underwent VF steroid injection after LMS were set as the injection group, and patients who had similar sex, age, and lesion size and who underwent LMS alone were set as the control group. In each group, stroboscopy, multi-dimensional voice program, Aerophone II, and voice handicap index (VHI) were performed before and 1 month after surgery, and the results were statistically analyzed. @*Results@#There were no statistically significant differences in the distribution of sex, age, symptom duration, occupation and smoking status between each group. Both groups consisted of VF polyp (n=21), Reinke’s edema (n=11), and leukoplakia (n=9). On stroboscopy, the lesion disappeared after surgery, and the amplitude and mucosal wave were symmetrical on both sides of the VFs in all patients. Acoustic parameters and VHI significantly improved after surgery in all patients. However, there was no significant difference between the injection and control group in most of the results. @*Conclusion@#There was no significant difference in the results of stroboscopy, acoustic, aerodynamic, and subjective evaluation before and after surgery in the injection group and the control group.

ABSTRACT

Background@#Cervical cancer is a prevalent malignancy that is a major health problem for women worldwide. The cancer-preventive properties of metformin are well-known, but insufficient data have been reported regarding its relationship to cervical cancer. Therefore, in a nationwide population-based study, we investigated the association between metformin use and cervical cancer incidence in patients with newly diagnosed type 2 diabetes. @*Methods@#This retrospective cohort study used the Korean National Health Insurance claims database. Individuals newly diagnosed with type 2 diabetes between January 2005 and December 2009 were included. The occurrence of cervical cancer was explored by matching for age, economic status, region of residence, and use of anti-diabetic medication. @*Results@#In total, 66,013 metformin users and 64,756 non-users were analyzed. Cervical cancer occurred in 219 metformin users (0.33%) and 274 metformin non-users (0.42%) (hazard ratio [HR], 0.783; 95% confidence interval [CI], 0.655 to 0.036; P=0.007). Moreover, cervical cancer risk was considerably reduced in those treated with a high dose (>1,200,000 mg) or for an extended period (≥2,000 days) compared to non-users (HR, 0.151; 95% CI, 0.093 to 0.243; P<0.001; and HR, 0.141; 95% CI, 0.077 to 0.258; P<0.001). The incidence was also significantly lower in metformin users among those over 50 years old (HR, 0.791; 95% CI, 0.650 to 0.961; P<0.001). @*Conclusion@#Metformin use in patients with newly diagnosed diabetes was associated with a lower risk of cervical cancer in Korea. Furthermore, a significant association was found between the use of metformin and cervical cancer in a dose- and duration-dependent manner and among those over 50 years old.

ABSTRACT

Objective@#Patients with post-traumatic stress disorder (PTSD) showed inconsistencies in their cortisol level, an index of the hypothalamic-pituitary-adrenal axis function. This study examined the relationship between dissociation, childhood trauma, and morning cortisol levels in PTSD patients. @*Methods@#This study included 69 (23 males and 46 females) patients and 82 (22 males and 60 females) healthy controls (HCs). Clinical assessments, including the Childhood Trauma Questionnaire (CTQ) and Peri-traumatic Dissociative Experiences Questionnaire scores, and morning cortisol levels were evaluated. The morning cortisol levels were compared between PTSD with high dissociation and low dissociation (PTSD-LD) groups. The effect of CTQ subtype on morning cortisol levels was analyzed. @*Results@#The PTSD with high dissociation group showed significantly lower cortisol levels than that of the PTSD-LD and HC groups. A significant inverse correlation was found between cortisol levels and dissociation. A significant positive correlation was found between dissociation and physical abuse and sexual abuse scores. Morning cortisol levels showed a significant positive correlation with emotional abuse, emotional neglect, and physical neglect, respectively. There was no moderating or mediating effect of CTQ on the relationship between cortisol level and dissociation. @*Conclusion@#These findings suggest that dissociation is a significant factor related to hypocortisolism in PTSD patients.Additionally, basal morning cortisol levels and dissociation scores were closely associated with childhood trauma.

ABSTRACT

Lipidomics coverage improvement is essential for functional lipid and pathway construction.A powerful approach to discovering organism lipidome is to combine various data acquisitions,such as full scan mass spectrometry(full MS),data-dependent acquisition(DDA),and data-independent acquisition(DIA).Caenorhabditis elegans(C.elegans)is a useful model for discovering toxic-induced metabolism,high-throughput drug screening,and a variety of human disease pathways.To determine the lipidome of C.elegans and investigate lipid disruption from the molecular level to the system biology level,we used integrative data acquisition.The methyl-tert-butyl ether method was used to extract L4 stage C.elegans after exposure to triclosan(TCS),perfluorooctanoic acid,and nanopolystyrene(nPS).Full MS,DDA,and DIA integrations were performed to comprehensively profile the C.elegans lipidome by Q-Exactive Plus MS.All annotated lipids were then analyzed using lipid ontology and pathway analysis.We annotated up to 940 lipids from 20 lipid classes involved in various functions and pathways.The biological in-vestigations revealed that when C.elegans were exposed to nPS,lipid droplets were disrupted,whereas plasma membrane-functionalized lipids were likely to be changed in the TCS treatment group.The nPS treatment caused a significant disruption in lipid storage.Triacylglycerol,glycerophospholipid,and ether class lipids were those primarily hindered by toxicants.Finally,toxicant exposure frequently involved numerous lipid-related pathways,including the phosphoinositide 3-kinase/protein kinase B pathway.In conclusion,an integrative data acquisition strategy was used to characterize the C elegans lipidome,providing valuable biological insights into hypothesis generation and validation.

ABSTRACT

OBJECTIVE@#To explore the expression characteristics of antigens and functional markers of natural killer (NK) cells in patients with acute myeloid leukemia (AML).@*METHODS@#Multi-parameter flow cytometry was used to detect NK cell surface markers and their functional indicators in 56 newly diagnosed AML patients and 24 healthy controls, including activating receptors NKG2D, NKP46, DNAM-1, and killing indicators granzyme B, perforin.@*RESULTS@#Referring to the WHO hematopoiesis and lymph tissue tumor classification criteria, 56 cases were roughly divided into three types: AML M1, M2, and M4/M5. However, there was no differences about NK cells among the three types, so it was no longer subdivided. NK cells were divided into two groups: CD3-CD56hiCD16- (CD56hiNK) and CD3-CD56dimCD16+ (CD56dimNK). Compared with CD56dimNK cell population, except for NKP46, the positive expression levels of NKG2D and other receptors of CD56hiNK cells in AML patients decreased (P<0.001). Compared with healthy controls, the proportion of CD56hiNK cells in AML patients increased, while the number and proportion of NK cells and proportion of CD56dimNK cells significantly decreased (P<0.05). The proportion of perforin in CD56hiNK cells significantly increased (P<0.05). The expression of DNAM-1 in CD56hiNK cells, NKG2D, DNAM-1, and perforin in CD56dimNK cells decreased significantly (P<0.05). There was no statistically significant difference in expression of other functional indexes in AML patients compared with corresponding indexes of healthy controls. In addition, the proportion of CD56hiNK cells was positively correlated with the expression of CD34+ in AML (r=0.303).@*CONCLUSION@#Compared with CD56dimNK, the ratio of CD56hiNK and the expression of functional markers in AML patients are lower. Compared with healthy controls, the number and expression ratio of NK cells in AML patients decrease and the expression of functional markers is abnormal, indicating that its function is impaired.

ABSTRACT

Objective@#This study examined the path model predicting suicide attempts (SA) by interpersonal need for suicide desire, acquired capability for suicide, the emotion dysregulation, and depression symptoms in people admitted to hospitals for medical treatment. @*Methods@#A total of 344 participants (200 depressed patients with attempted suicide, 144 depressed patients with suicidal ideation) were enrolled for this study. Depression, anxiety, emotion regulation, interpersonal needs, and acquired capability for suicide were evaluated. A model with pathways from emotion regulation difficulties and interpersonal needs to SA was proposed. Participants were divided into two groups according to the presence of SA or suicidal ideation. @*Results@#Acquired capability for suicide mediated the path from depression to SA. In the path model, difficulties in emotion regulation and interpersonal needs predicted depression significantly. Although depression itself was not significantly related to acquired capability for suicide, depression was significantly related to acquired capability for suicide in suicide attempter group. @*Conclusion@#Interventions with two factors affecting SA will clarify the suicide risk and contribute to finding risk factors.

ABSTRACT

Neuroendocrine carcinoma (NEC) is a rare form of hormone-secreting tumor. NECs originate from the epithelial cells of the larynx and account for less than 1% of the laryngeal neoplasm. Most cases of NECs are diagnosed by pathological confirmation after surgery. The terminology of laryngeal NEC has been a source of confusion. In 2017, World Health Organization newly categorized laryngeal NEC; as a result, the large cell type, which has been the main target of disagreement, was finally included into a subtype of poorly differentiated NEC. We report a case of a 58-year-old male with a growing granulomatous mass in the posterior supraglottis. The granuloma was removed by surgical excision when the size of the mass increased. He was diagnosed with the large cell type laryngeal NEC by pathological confirmation. He underwent postoperative radiotherapy and is currently being followed up in our outpatient clinic without evidence of recurrence.

ABSTRACT

Thoracic endovascular aortic repair has served as the predominant treatment approach for patients with thoracic aortic diseases. In order to ensure the successful release of the stent as well as a good proximal anchoring effect, it is necessary to preserve or reconstruct the left subclavian supply as much as possible. With the advance of various endovascular assistive technologies, different left subclavian artery revascularization techniques have gained widespread acceptance. So far, techniques include carotid-subclavian bypass or transposition, chimney grafts, fenestrations, branched aortic devices can reconstruct the left subclavian artery and other branch vessels on the arch. This article reviewed the present situation of left subclavian artery reconstruction and the selection of surgical methods of thoracic endovascular aortic repair.

ABSTRACT

Objective@#To establish an ultra-sensitive, ultra-fast, visible detection method for Vibrio parahaemolyticus (VP) .@*Methods@#We established a new method for detecting the tdh and trh genes of VP using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 12a (CRISPR/Cas12a) combined with recombinase polymerase amplification and visual detection (CRISPR/Cas12a-VD).@*Results@#CRISPR/Cas12a-VD accurately detected target DNA at concentrations as low as 10 -18 M (single molecule detection) within 30 min without cross-reactivity against other bacteria. When detecting pure cultures of VP, the consistency of results reached 100% compared with real-time PCR. The method accurately analysed pure cultures and spiked shrimp samples at concentrations as low as 10 2 CFU/g.@*Conclusion@#The novel CRISPR/Cas12a-VD method for detecting VP performed better than traditional detection methods, such as real-time PCR, and has great potential for preventing the spread of pathogens.

ABSTRACT

Myofibrosarcoma is a rare malignant tumor originating from myofibroblasts. It is classified into low-grade, intermediate-grade, and high-grade according to the histological characteristics. High-grade myofibrosarcoma is reported very rarely worldwide, and its recurrence and metastasis are known to be more common. Myofibrosarcoma is diagnosed by histopathologic examination, and its treatment is complete surgical excision. With a review of literature, we report a case of myofibrosarcoma originating from the right masseter muscle in a 73-year-old male patient who complained of a right chin mass for 4 months. The MRI findings revealed a 4.8 cm-sized heterogeneous contrast-enhancing mass in the right masseter muscle with direct invasion into the ipsilateral medial pterygoid muscle and the mandible body. The patient was treated with margin-free surgical excision, including marginal mandibulectomy, and a highgrade myofibrosarcoma was finally diagnosed as the pathologic finding. Adjuvant radiation therapy was performed as a subsequent treatment, and no recurrence has been observed during follow-up for 1 year.

ABSTRACT

Objective@#This study aims to understand borderline personality disorder (BPD) features by employing the Personality Psychopathology Five (PSY-5) scales from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). @*Methods@#A total of 156 psychiatric patients completed PSY-5 scales of MMPI-2 and Personality Assessment Inventory-Borderline Subscale (PAI-BOR). Pearson’s partial correlation analysis was conducted to control the impact of age and gender and to determine the relationship between PSY-5 scales and BOR. A hierarchical multiple regression analysis was implemented to examine whether PSY-5 scales predicted the BOR-total, and a path analysis was performed to determine whether PSY-5 scales predicted each PAI-BOR subscale. @*Results@#The BOR-total score had a significant correlation with all PSY-5 scores, even after controlling for age and gender. However, only aggressiveness (AGGR), disconstraint (DISC), negative emotionalityeuroticism (NEGE), and introversion/low positive emotionality (INTR), excluding psychoticism (PSYC), significantly predicted BOR-total. The path analysis indicates that PSYC did not predict any BOR subscale, while NEGE predicted all BOR subscales. @*Conclusion@#The study findings indicate that NEGE best reflects BPD features, while PSYC is far from the core domain that describes BPD. In addition, the influence of age should be considered when understanding BPD, since age predicted the BOR-total and two BOR subscales.

ABSTRACT

Objective@#After Women's Health Initiative (WHI) trial, hormone replacement therapy (HRT) prescription rate dropped by 16% in Korea. We investigated the relationship between the type of HRT and incidence of breast cancer (BC) in postmenopausal women in Korea.Material & Methods: We compared the prevalence of BC in 356,160 women on HRT, who reached menopause between 2004 and 2007. We divided the type and duration of HRT into three categories, i.e., estrogen-progestogen therapy (EPT), estrogen-only therapy (ET), tibolone, and 1– 3 years, 3–5 years, and >5 years, respectively. @*Results@#Regarding the type of HRT among all age groups, BC risk (BCR) was lower in the tibolone group (P<0.01). Based on age group, BCR was lower in the 50–59 years group using EPT (P=0.03) and tibolone (P<0.01). HRT administration for <3 years showed a significant decrease in the tibolone group (P=0.04) and an increase in the ET group (P=0.03). In groups undergoing HRT for >5 years, BCR in all groups decreased (P<0.05). @*Conclusions@#The results suggest that tibolone reduces the risk of BC in women aged ≥50 years and HRT use for ≥5 years was related to significantly decreased BCR in Korea.

ABSTRACT

Purpose@#Sleep-disordered breathing is one of the complicating characteristics in patients with Prader-Willi syndrome (PWS). No detailed description and risk factors are suggested on breathing problems during sleep in Korean children with PWS. @*Methods@#We reviewed clinical and sleep-study data in patients with PWS who underwent polysomnography before they took the growth hormone therapy. @*Results@#Of the 27 patients with PWS, 25 (92.6%) had sleep-disordered breathing, of whom 14 showed moderate to severe sleep apnea. Obstructive dominance was prevalent (64%), followed by central dominance (24%). The apnea-hypopnea index (AHI) increased with increasing weight-for-height z-score (WHZ) (r = 0.50, P = 0.009), but did not differ by age. Apnea duration of over 12 months was longer in the patient group than in the infant group (15.1 ± 4.3 seconds vs. 9.4 ± 1.7 seconds, P = 0.001) and in the obese than nonobese groups (16.8 ± 4.3 seconds vs. 10.0 ± 2.0 seconds, P = 0.003). Desaturation below 70% was more common in the obese than nonobese subjects (3/9 vs. 0/18, P = 0.029). Age was not different between the central and obstructive apnea groups, but patients with central apnea tended to be younger than patients with obstructive apnea (median [range]: 8.0 months [6.0–12.0 months] vs.16.5 months [8.5–79.5 months], P = 0.092). In addition, patients with obstructive apnea showed higher AHI (12.8 [5.9–19.2] vs. 3.9 [3.4–4.5], P = 0.045). @*Conclusion@#Sleep-disordered breathing is common in PWS children with different intensity and patterns according to age and BMI. Close monitoring of breathing problems during sleep is required in PWS patients.

ABSTRACT

Objective:To investigate the short-term effects of staged hybrid abdominal aortic debranching technique in the treatment of thoracoabdominal aorta.Methods:From January 2018 to December 2018, 22 patients with thoracoabdominal aortic aneurysms underwent surgical treatment in Nanjing Drum Tower Hospital. Among them, 12 underwent staged hybrid abdominal aortic debranching (AAD), and 10 underwent traditional thoracoabdominal aortic replacement (TAR). AAD consisted of two phases: the first phase of surgery was mid-opening, Y-type artificial blood vessels replaced the lower abdominal aorta and bilateral common iliac arteries, and the abdominal aortic branches were reconstructed at the same time: right branch artificial blood vessels-right renal artery-left renal artery, the left branch artificial blood vessel-superior mesenteric artery-common hepatic artery; the second phase was endovascular repair anchoring normal and long-term normal aorta or artificial blood vessel. The clinical effected of two methods for the treatment of thoracoabdominal aortic aneurysms were compared and analyzed.Results:The overall mortality rate was 13.6%, and the mortality rate in the TAR group increased significantly (0 vs. 30%). The main cause was dissection (91.7% vs. 90.0%, P=0.895). Crawford classification was predominantly type Ⅱ in both groups(58.3% vs. 50.0%, P=0.082). The proportion of patients with Marfan syndrome in the TAR group was higher (30% vs. 0, P=0.046). The TAR group was significantly more drained 24 h after surgery [(355.0±199.2)ml vs. (1244.0±716.1)ml, P= 0.003]. The TAR group had a higher proportion of lung infections (40% vs. 0, P= 0.018). The average cost was higher in the AAD group [(28.4±8.3) ten thousands yuan vs. (19.3±10.4) ten thousands yuan, P= 0.033]. Conclusion:The staged hybrid abdominal aortic debranching technique can effectively treat thoracoabdominal aortic aneurysms. Compared with traditional thoracoabdominal aortic replacement, the surgical trauma is smaller but more expensive.
