Diagnostic and prognostic value of parameters of erector spinae in patients with uremic sarcopenia.

AIM: This study aimed to investigate whether computed tomography (CT)-measured erector spinae parameters (ESPs) have diagnostic, severity assessment, and prognostic predictive value in uremic sarcopenia (US). MATERIALS AND METHODS: A total of 202 uremic patients were enrolled and divided into two groups: a control group and a sarcopenia group. Sarcopenia was classified into two types: severe and nonsevere. The area, volume, and density of the erector spinae (ES) were measured using chest CT images, and the relevant ESP, including the erector spinae index (ESI), total erector spinae volume (TESV), erector spinae density (ESD), and erector spinae gauge (ESG) were calculated. The occurrence of adverse events was followed-up for 36 months. The diagnostic value and severity of US were determined using the receiver operating characteristic (ROC) curve. Survival curves diagnosed using CT were plotted and compared with the curve drawn using the gold standard. Cox regression analysis was used to identify independent risk factors associated with survival in US. RESULTS: With an area under the curve (AUC) of 0.840 and 0.739, the combined ESP has diagnostic value and the ability to assess the severity of US. There was no significant difference in the survival curve between the combined ESP for the diagnosis of US and the gold standard (P > 0.05). ESI is a standalone predictor of survival in patients with US. CONCLUSION: ESP measured by CT has diagnostic values for US and its severity, as well as being a predictive value for the prognosis of US.

[Diagnosis and treatment understanding of Waldenström macroglobulinemia in China: a cross-sectional study].

Objective: To conduct a nationwide physician survey to better understand clinicians' disease awareness, treatment patterns, and experience of Waldenström macroglobulinemia (WM) in China. Methods: This cross-sectional study was conducted from February 2022 to July 2022 by recruiting clinicians with WM treatment experience from hematology, hematology-oncology, and oncology departments throughout China. Quantitative surveys were designed based on the qualitative interviews. Results: The study included 415 clinicians from 219 hospitals spread across thirty-three cities and twenty-two provinces. As for diagnosis, the laboratory tests prescribed by physicians for suspected WM patients were relatively consistent (92% -99% recommendation for laboratory, 79% -95% recommendation for pathology, 96% recommendation for gene testing, and 63% -83% recommendation for imaging examination). However, from a physician's perspective, there was 22% misdiagnosis occurred in clinical practice. The rate of misdiagnosis was higher in lower-level hospitals than in tertiary grade A hospitals (29% vs 21%, P<0.001). The main reasons for misdiagnosis were that WM was easily confused with other diseases, and physicians lacked the necessary knowledge to make an accurate diagnosis. In terms of gene testing in clinical practice, 96% of participating physicians believed that WM patients would require gene testing for MYD88 and CXCR4 mutations because the results of gene testing would aid in confirming diagnosis and treatment options. In terms of treatment, 55% of physicians thought that the most important goal was to achieve remission, while 54% and 51% of physicians wanted to improve laboratory and/or examination results and extend overall survival time, respectively. Among patients with treatment indications, physicians estimated that approximately 21% of them refused to receive treatment, mainly owing to a lack of affordable care and disease awareness. When selecting the most appropriate treatment regimens, physicians would consider patient affordability (63% ), comorbidity (61% ), and risk level (54% ). Regimens containing Bruton tyrosine kinase inhibitor (BTKi) were most widely recommended for both treatment-naïve and relapsed/refractory patients (94% for all patients, 95% for treatment-naïve patients, and 75% for relapsed/refractory patients), and most physicians recommended Ibrutinib (84% ). For those patients who received treatment, physicians reported that approximately 23% of patients did not comply with the treatment regimen due to a lack of affordability and disease awareness. Furthermore, 66% of physicians believe that in the future, increasing disease awareness and improving diagnosis rates is critical. Conclusions: This study is the first national physician survey of WM conducted in China. It systematically describes the issues that exist in WM diagnosis and treatment in China, such as a high rate of misdiagnosis, limited access to gene testing and new drugs, and poor patient adherence to treatment. Chinese doctors believe that improving doctors' and patients' understanding of WM is one of the most urgent issues that must be addressed right now.

[Clinical characteristics of 11 patients with Vibrio vulnificus infection and the establishment of a rapid diagnosis procedure for this disease].

Objective: To analyze the clinical characteristics of patients with Vibrio vulnificus infection, share diagnosis and treatment experience, and establish a rapid diagnosis procedure for this disease. Methods: This study was a retrospective case series study. From January 2009 to November 2022, 11 patients with Vibrio vulnificus infection who met the inclusion criteria were admitted to the Department of Burns and Wound Repair of Guangdong Provincial People's Hospital Affiliated to Southern Medical University. The gender, age, time of onset of illness, time of admission, time of diagnosis, route of infection, underlying diseases, affected limbs, clinical manifestations and signs on admission, white blood cell count, hemoglobin, platelet count, C-reactive protein (CRP), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, procalcitonin, albumin, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and blood sodium levels on admission, culture results and metagenomic next-generation sequencing (mNGS) results of pathogenic bacteria and the Vibrio vulnificus drug susceptibility test results during hospitalization, treatment methods, length of hospital stay, and outcomes of all patients were recorded. Comparative analysis was conducted on the admission time and diagnosis time of patients with and without a history of exposure to seawater/marine products, as well as the fatality ratio and amputation of limbs/digits ratio of patients with and without early adequate antibiotic treatment. For the survived patients with hand involvement, the hand function was assessed using Brunnstrom staging at the last follow-up. Based on patients' clinical characteristics and treatment conditions, a rapid diagnosis procedure for Vibrio vulnificus infection was established. Results: There were 7 males and 4 females among the patients, aged (56±17) years. Most of the patients developed symptoms in summer and autumn. The admission time was 3.00 (1.00, 4.00) d after the onset of illness, and the diagnosis time was 4.00 (2.00, 8.00) d after the onset of illness. There were 7 and 4 patients with and without a history of contact with seawater/marine products, respectively, and the admission time of these two types of patients was similar (P>0.05). The diagnosis time of patients with a history of contact with seawater/marine products was 2.00 (2.00, 5.00) d after the onset of illness, which was significantly shorter than 9.00 (4.25, 13.00) d after the onset of illness for patients without a history of contact with seawater/marine products (Z=-2.01, P<0.05). Totally 10 patients had underlying diseases. The affected limbs were right-hand in 8 cases, left-hand in 1 case, and lower limb in 2 cases. On admission, a total of 9 patients had fever; 11 patients had pain at the infected site, and redness and swelling of the affected limb, and 9 patients each had ecchymosis/necrosis and blisters/blood blisters; 6 patients suffered from shock, and 2 patients developed multiple organ dysfunction syndrome. On admission, there were 8 patients with abnormal white blood cell count, hemoglobin, and albumin levels, 10 patients with abnormal CRP, procalcitonin, and NT-proBNP levels, 5 patients with abnormal creatinine and blood sodium levels, and fewer patients with abnormal platelet count, ALT, and AST levels. During hospitalization, 4 of the 11 wound tissue/exudation samples had positive pathogenic bacterial culture results, and the result reporting time was 5.00 (5.00, 5.00) d; 4 of the 9 blood specimens had positive pathogenic bacterial culture results, and the result reporting time was 3.50 (1.25, 5.00) d; the mNGS results of 7 wound tissue/exudation or blood samples were all positive, and the result reporting time was 1.00 (1.00, 2.00) d. The three strains of Vibrio vulnificus detected were sensitive to 10 commonly used clinical antibiotics, including ciprofloxacin, levofloxacin, and amikacin, etc. A total of 10 patients received surgical treatment, 4 of whom had amputation of limbs/digits; all patients received anti-infection treatment. The length of hospital stay of 11 patients was (26±11) d, of whom 9 patients were cured and 2 patients died. Compared with that of the 6 patients who did not receive early adequate antibiotic treatment, the 5 patients who received early adequate antibiotic treatment had no significant changes in the fatality ratio or amputation of limbs/digits ratio (P>0.05). In 3 months to 2 years after surgery, the hand function of 8 patients was assessed, with results showing 4 cases of disabled hands, 2 cases of incompletely disabled hands, and 2 cases of recovered hands. When a patient had clinical symptoms of limb redness and swelling and a history of contact with seawater/marine products or a pre-examination triage RiCH score of Vibrio vulnificus sepsis ≥1, the etiological testing should be initiated immediately to quickly diagnose Vibrio vulnificus infection. Conclusions: Vibrio vulnificus infection occurs most frequently in summer and autumn, with clinical manifestations and laboratory test results showing obvious infection characteristics, and may be accompanied by damage to multiple organ functions. Both the fatality and disability ratios are high and have a great impact on the function of the affected limbs. Early diagnosis is difficult and treatment is easily delayed, but mNGS could facilitate rapid detection. For patients with red and swollen limbs accompanied by a history of contact with seawater/marine products or with a pre-examination triage RiCH score of Vibrio vulnificus sepsis ≥1, the etiological testing should be initiated immediately to quickly diagnose Vibrio vulnificus infection.

[ANCA-negative granulomatosis with polyangiitis: a case report].

We reported a case of 73-year-old male with multiple pulmonary nodules and cavities. The patient was admitted with a chief complaint of "dry cough with shortness of breath for 3 months". Chest CT showed multiple irregular masses, nodules, and patchy lesions in both lungs, accompanied by the formation of cavities. He also had anemia and renal dysfunction. Despite given empirical anti-infective and anti-tuberculosis treatments, the pulmonary nodules progressed, and the cavities enlarged. Anti-neutrophil cytoplasmic antibodies (ANCA) were negative twice. Bronchoscopic biopsy was performed. The mucosal pathology of the right middle lobe lesion showed little necrosis, focal granulomatous structure formation, and relevant vasculitis and remaining vessel wall structure in the necrosis lesions by elastic fiber staining. A clinical diagnosis of ANCA-negative necrotizing granulomatous polyangiitis was made and the patient was treated with glucocorticoids and cyclophosphamide. The nodules and cavities shrank, and some lesions were absorbed.

[Effectiveness of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022].

OBJECTIVE: To evaluate the effectiveness of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, so as to provide insights into echinococcosis control. METHODS: Administrative villages were sampled using a multi-stage cluster random sampling method from Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, and all residents at ages of 12 years and older in the sampled villages were screened for echinococcosis, and schools were sampled using a cluster sampling method, and all children at ages of 12 years and older in the sampled schools were screened for echinococcosis. Domestic dogs were sampled using a systematic random sampling method, and one domestic dog stool sample was collected from each household. Stray dog stool samples were collected outside the villages, and Echinococcus coproantigens were detected using enzyme-linked immunosorbent assay in domestic and stray dogs. In addition, echinococcosis was screened in sheep and cattle in designated slaughterhouses in Tianzhu Tibetan Autonomous County. The trends in the prevalence of echinococcosis in humans and livestock and the positive rate of Echinococcus coproantigens in dogs were examined with the Cochran-Armitage trend test. In addition, individuals screened for echinococcosis were randomly sampled from 2007 to 2022 for survey on the awareness of echinococcosis control knowledge. RESULTS: A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ2 = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ2 = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ2 = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ2 = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ2 = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ2 = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively. CONCLUSIONS: There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.

Association between healthy lifestyle combinations and periodontitis in NHANES.

BACKGROUND: Periodontitis is closely associated with chronic systemic diseases. Healthy lifestyle interventions have health-enhancing effects on chronic systemic disorders and periodontitis, but the extent to which healthy lifestyle combinations are associated with periodontitis is unclear. Therefore, this study aimed to investigate the association between periodontitis and different healthy lifestyle combinations. METHODS: 5611 participants were included from the National Health and Nutrition Examination Survey (NHANES, 2009-2014). Six healthy lifestyles factors were defined as fulfilling either: non-smoking, moderate drinking, moderate body mass index (BMI), physical activity, healthy sleep and appropriate total energy intake. Then, the adjusted logistic regression models were performed to identify the association between the periodontitis and the scoring system composed of six lifestyles (0-6 scale). Finally, different scenarios were dynamically and randomly combined to identify the optimal and personalized combination mode. RESULTS: Higher healthy lifestyle scores were significantly associated with lower periodontitis prevalence (p < 0.05). Four lifestyle factors (smoking, drinking, BMI, and sleep) significantly varied between the periodontitis and healthy groups (p < 0.05). Smoking was considered as a strong independent risk factor for periodontitis in both former and current smokers. Results further indicated that the combination of these four lifestyles played the most essential role in determining the magnitude of periodontitis occurrence (odds ratio [OR]: 0.33; 95% confidence interval [CI]: 0.21 to 0.50). In the total population, the majority of three lifestyle combinations outperformed the two combination models, whereas the two-combination of nonsmoking-drinking (OR: 0.39; 95% CI: 0.27 to 0.58) had relatively lower periodontitis prevalence than the three-combination of healthy drinking-BMI-sleep (OR: 0.42; 95% CI: 0.26 to 0.66). CONCLUSION: This cross-sectional study suggests that smoking, drinking, BMI, and sleep are significantly related with periodontitis and smoking is the principal risk factor related among them. This study provides various customized lifestyle combinations for periodontitis prevention.

Role of low-density lipoprotein in mediating the effect of air pollution on coronary heart disease: a two-step multivariate Mendelian randomization study.

OBJECTIVE: Air pollution is affecting the health of millions of people all over the world. The causal correlations of PM2.5, PM10, and nitrogen dioxide (NOx), as the main fine particulate matter, and coronary heart disease (CHD) are yet to be explored. Low-density lipoprotein (LDL) has been a principal factor in the pathogenesis of CHD. It is an interesting issue to consider whether LDL mediates the effect of air pollutants in CHD pathogenesis. MATERIALS AND METHODS: A genome-wide association study (GWAS) on the European population, followed up from 2010 to 2018, involving over 400,000 participants, was based on a land-use regression model. The annual mean concentrations of major air pollutant particles, PM2.5 (n=423,796), PM10 (n=423,796), and NOx (n=456,380), were recorded. The large GWAS database of CHD covered over ten million SNPs with independent single nucleotide polymorphisms (SNPs). LDL database collected major biochemical blood parameters from over 400,000 patients (n=440,546). Taken together, we conducted independent two-sample Mendelian randomization (MR) analyses for the causality between air pollutants (PM2.5, PM10, and NOx) and CHD. Multivariate MR analysis was conducted using causal relationships to determine the direct effects of exposure on outcome. The fixed-effect inverse variance weighted (IVW2) method was mainly employed to assess this relationship, with a confidence interval of 95% for the odds ratio (OR). Also, MR-Egger, weighted median, maximum likelihood ratio method, and random-effects inverse variance-weighted (IVW1) method were adopted as supplementary methods. RESULTS: Two-sample MR results based on the IVW2 method suggested positive correlations between PM2.5 and CHD [OR 1.875 (1.279-2.748), p=0.001], PM10 and CHD [OR 2.586 (1.479-4.523), p=0.001], and NOx and CHD [OR 2.991 (2.021-4.427), p=4.37E-08]. The direct effect and mediating proportion were calculated using multivariable Mendelian randomization (MVMR). Lastly, the mediating proportions of LDL in the regulatory roles of PM2.5, PM10, and NOx in CHD were 2.82%, 4.73%, and 9.54%, respectively. CONCLUSIONS: PM2.5, PM10, and NOx share direct causal associations with CHD, and LDL performs a mediating role in this pathogenic process. Early prevention against air pollution (such as increasing green areas and reducing large-scale industrial dust emissions) and early lipid-lowering treatment can effectively prevent the occurrence of CHD.

[Analysis on early predictors of respiratory depression in patients with glufosinate poisoning].

Objective: To investigate the early predictors of respiratory depression in patients with glufosinate poisoning, and provide reference for clinicians to make decisions. Methods: In March 2022, the clinical data of patients with glufosinate poisoning admitted to the intensive care unit of the Affiliated Xiangshan Hospital of Wenzhou Medical University from March 2018 to January 2022 were retrospectively analyzed. The patients were divided into respiratory depression group and non-respiratory depression group according to the occurrence of respiratory depression during hospitalization. The clinical data such as age, gender, past history, intake, initial treatment and laboratory examination were compared between the two groups. Multivariate logistic regression was used to analyze the predictors of respiratory depression in patients with glufosinate poisoning, and its predictive value was analyzed by receiver operating characteristic (ROC) curve. Results: A total of 34 patients with glufosinate poisoning were enrolled, including 13 patients in non-respiratory depression group and 21 patients in respiratory depression group. There were significant differences in intake, blood amylase and bicarbonate radical in arterial blood gas between the two groups (P<0.05). Respiratory depression occurred at 6.5-48.0 h after ingestion, with a median of 15.0 (9.5, 24.0) h. Multivariate logistic regression analysis showed that the intake of glufosinate (OR=1.440, 95%CI: 1.033-2.009, P=0.032) and bicarbonate radical in arterial blood gas (OR=0.199, 95%CI: 0.040-0.994, P=0.049) were predictors of respiratory depression in patients with glufosinate poisoning, and the area under the curve (AUC) of ROC curves were 0.936 and 0.842. The optimal cut-off values were 15.0 g (sensitivity=95.2%, specificity=76.9%) and 17.6 mmol/L (sensitivity=71.4%, specificity=84.6%), respectively. Conclusion: The intake of glufosinate and bicarbonate radical in arterial blood gas have good prediction effects on the occurrence of respiratory depression in patients with glufosinate poisoning.

[Survey on monkeypox knowledge awareness, risk perception and vaccination intention in men who have sex with men in five cities in northeast China].

Objective: To understand the monkeypox knowledge awareness, risk perception and vaccination intention in men who have sex with men (MSM) in five cities in northeast China. Methods: A cross-sectional study was conducted by using electronic questionnaire in MSM selected by convenience sampling in five cities in northeast China (Shenyang, Panjin, Changchun, Harbin and Jiamusi) from June 28 to July 8, 2023 by local centers for disease control and prevention and MSM communities. The sample size was estimated to be 220. Information about their demographics, monkeypox-related knowledge awareness, perceived concern about epidemic risk perception, and monkeypox vaccination intention were collected. Logistic regression model was used to analyze related factors for MSM's monkeypox vaccination intention. Results: In 355 MSM, 63.9% (227/355) had monkeypox vaccination intentions, and 55.5% (197/355) had high awareness of monkeypox related knowledge with a mean knowledge awareness score of 3.7±1.5. MSM with education level of high-school and above (aOR=1.93, 95%CI:1.01-3.69), higher knowledge awareness score (aOR=1.19, 95%CI:1.02-1.40) and higher risk perception of monkeypox infection (aOR=1.82, 95%CI:1.15-2.88), were more willing to receive monkeypox vaccination. The main reasons for willingness to receive monkeypox vaccine were preventing monkeypox (86.3%, 196/227) and worrying about appearance being affected (62.1%, 141/227). The main reasons for unwillingness for the vaccination included concerns about vaccine safety (53.1%, 68/128), clinical progression of AIDS being affected (46.1%, 59/128) and efficacy of antiretroviral therapy being affected (44.5%, 57/128). Conclusions: The levels of knowledge awareness and vaccine intentions still need to be improved among MSM in five cities of northeast China. It is necessary to improve the awareness of monkeypox and intention of monkeypox vaccination, promote protected sex behavior and self-assessment of infection risk, reduce vaccine hesitancy and increase monkeypox vaccination intention in MSM in 5 cities in northeast China.

[Clinical features of peripheral neuropathy with livedo reticularis: an analysis of seven cases].

The clinical characteristics, auxiliary examinations, skin and neuropathological features of 7 patients who had reticular cyanosis with peripheral neuropathy from the Department of Neurology, Huashan Hospital, Fudan University from January 2019 to December 2022 were retrospectively analyzed. Among the 7 patients, 5 were female and 2 were male.The age of onset of peripheral neuropathy was (39.8±21.3) years and the disease duration of peripheral neuropathy was (2.7±2.3) years. Three patients had acute onset and 4 patients had chronic onset. All the patients had limb numbness, with limb weakness in 6 patients and pain in 5 cases. Neuroelectrophysiological examination revealed 1 case of mononeuropathy, 2 cases of polyneuropathy, 2 cases of peripheral neuropathy, and 2 cases of sensory neuron neuropathy. Skin biopsy was performed in 3 patients, which presented hyperplasia and expansion of blood vessels in the dermis with lymphocyte infiltration. Nerve biopsy was performed in 3 patients, indicating axonal damage. Reticular cyanosis with peripheral neuropathy characterizes with numbness and weakness of limbs, most of which were accompanied by pain. Electrophysiological changes are in various forms. The pathological changes are dominated by the damage of axonal.

Biomechanical and aesthetic outcomes following radial forearm free flap transfer: comparison of ipsilateral full-thickness skin graft and traditional split-thickness skin graft.

The radial forearm free flap (RFFF) is associated with donor site morbidity. This study aimed to quantify the functional and aesthetic outcomes after closure of the RFFF donor site using triangular full-thickness skin grafts (FTSGs) harvested adjacent to the flap or traditional split-thickness skin grafts (STSGs). The study included patients who underwent oral cavity reconstruction with an RFFF between March 2017 and August 2021. The patients were divided into two groups based on the donor site closure method: FTSG or STSG. The primary outcomes were biomechanical grip strength, pinch strength, and range of wrist movements. Subjective donor site morbidity, aesthetic and functional results were also analysed. The study included 75 patients (FTSG n = 35; STSG n = 40). Postoperatively, there was a statistically significant difference in grip strength (P = 0.049) and wrist extension (P = 0.047) between the FTSG and STSG groups, in favour of the STSG. Differences between the groups in pinch strength and other wrist motions were not statistically significant. The harvesting time was significantly shorter for the FTSG (P = 0.041) and the appearance of the donor site was better (P = 0.026) when compared to the STSG. Cold intolerance was more frequent in the STSG group (32.5% STSG vs 6.7% FTSG; P = 0.017). Subjective function, numbness, pain, hypertrophic scar, itching, and social stigma did not differ significantly between the groups. Compared with the STSG, the FTSG showed better cosmesis and avoided additional donor sites, with clinically negligible differences in hand biomechanics.

Identification of ferroptosis-related diagnostic markers in primary Sjögren's syndrome based on machine learning.

BACKGROUND: Primary Sjogren's syndrome (pSS) is a common autoimmune disorder that affects up to 0.3-3% of the global population. Ferroptosis has recently been identified to play a significant role in autoimmune diseases. However, the molecular mechanisms of ferroptosis in the initiation and progression of pSS remains unclear. MATERIAL AND METHODS: To investigate the molecular mechanisms underlying the occurrence and progression of pSS, we utilized a comprehensive approach by integrating data obtained from the Gene Expression Omnibus (GEO) database with data from the FerrDb database to identify the ferroptosis-related differentially expressed genes (DEGs). Furthermore, we implemented an innovative transcriptomic analysis method utilizing a computer-aided algorithm to establish a network between hub genes associated with ferroptosis and the immune microenvironment in pSS patients. RESULTS: Our results revealed significant differences in the gene expression profiles of pSS samples compared to normal tissues, with 1,830 significantly up-regulated genes and 1,310 significantly down-regulated genes. In addition, our results showed a significant increase in the proportions of B cells and CD4+ T cells in pSS samples compared to normal tissues. AND then, our analysis revealed that a combination of six ferroptosis-related genes, including TBK1, SLC1A4, PIK3CA, ENO3, EGR1, and ATG5, could serve as optimal markers for the diagnosis of pSS. The combined analysis of these six genes accurately diagnosed the occurrence of pSS. CONCLUSIONS: This study offers valuable insights into the pathogenesis of pSS and highlights the importance of targeting ferroptosis-related DEGs, which suggests a novel treatment strategy for pSS.

Thoracic paravertebral nerve block combined laryngeal mask airway with preservation of spontaneous breathing can accelerate postoperative recovery.

OBJECTIVE: This study aimed to examine the potential benefits of Thoracic Paravertebral Nerve Block (TPVB) coupled with Laryngeal Mask Airway (LMA) and the maintenance of spontaneous breathing anesthesia, in contrast to general anesthesia utilizing double-lumen endobronchial intubation, on promoting recovery following thoracoscopic surgery. PATIENTS AND METHODS: A randomized controlled trial was carried out involving sixty patients set for Video-Assisted Thoracoscopic Surgery (VATS) at the Affiliated People's Hospital of Jiangsu University from February 2021 to January 2022. Patients were randomized to either the TPVB and LMA with spontaneous breathing anesthesia group (non-intubation group, NI group) or the general anesthesia with double-lumen endobronchial intubation group (Intubation group, I group). The primary outcome measured was the duration of hospitalization. Secondary outcomes included early postoperative rehabilitation indicators, postoperative complications, Visual Analogue Score (VAS), and inflammatory response markers. RESULTS: Patients in the NI group experienced significantly shorter hospital stays than those in the I group (p < 0.05). Early postoperative recovery, assessed by metrics including the first exhaust time, food intake time, first ambulation time, and duration of chest-tube placement, was superior in the NI group (p < 0.05). Postoperative complications such as nausea and vomiting, pulmonary infection, atelectasis, sore throat, and hoarseness, along with cortisol and C-reactive protein (CRP) levels at the end of the operation and 24 h post-operation, and VAS values within the first 12 h post-operation, were significantly lower in the NI group (p < 0.05). However, blood loss, operation time, and VAS values at 24 h and 48 h post-surgery showed no significant differences between the two groups. CONCLUSIONS: Our findings suggest that TPVB, in conjunction with LMA and spontaneous breathing anesthesia, may expedite postoperative recovery in patients undergoing VATS.

[The occurrence, precaution and treatment strategies of postoperative fecal incontinence in rectal and anal diseases].

In the surgical treatment of hemorrhoids, rectal prolapse, rectal cancer, anal fissures, or anal fistulas, inadvertent damage to the nerves or muscles responsible for bowel control may potentially lead to varying degrees of fecal incontinence (FI). Surgeons need to conduct preoperative assessments based on the patient's individual condition to select an appropriate surgical plan, aiming to minimize the incidence of postoperative FI and improve the patient's postoperative quality of life as much as possible while effectively treating the disease. Additionally, the proficiency of the surgeon's skills, appropriate preoperative dietary adjustments for the patient, regular bowel habits, and exercises targeting the pelvic floor muscles all contribute to reducing the incidence of postoperative FI in patients. For patients who have already developed FI after surgery, on the basis of suitable diet, regular bowel habits, and medication, clinical practitioners can adopt such methods as biofeedback, pelvic floor muscle exercise, sacral nerve stimulation, percutaneous tibial nerve stimulation, acupuncture, injectable bulking agents, anal or vaginal inserts, transanal irrigation, surgical interventions, psychological support, etc., to individualized treatment for patients' conditions. This article, combining the literature, summarizes the current status of common diseases that may lead to postoperative FI. It elaborates on strategies for the prevention and treatment of postoperative FI, aiming to serve as a reference for peers in the field.

[Clinical analysis of adult oculomoclonus-myoclonus syndrome with vertigo].

The clinical manifestation, physical and laboratory examination, electrophysiological, and imaging data of 2 female adult OMS patients with vertigo were analyzed at the Department of Neurology of the First Medical Center of Chinese PLA General Hospital from February 2021 to March 2022. The treatment strategy and clinical outcome were followed up. The two female patients were aged 42 and 66 years. Anti-NMDA receptor antibody and anti-GABAB receptor antibody were detected in serological screening, respectively. The two patients met the diagnostic criteria for OMS, and one was screened for breast tumor. The clinical symptoms of the two patients were relieved after immunomodulation therapy. OMS is a group of rare clinical syndromes; its clinical evaluation process should be standardized and the etiology should be actively searched for.

Quantum Reliability.

Quantum technology has led to increasingly sophisticated and complex quantum devices. Assessing their reliability (quantum reliability) is an important issue. Although reliability theory for classical devices has been well developed in industry and technology, a suitable metric on quantum reliability and its loss has not been systematically investigated. Since reliability loss depends on the process, quantum fidelity does not always fully depict it. This study provides a metric of quantum reliability by shifting the focus from state distinguishing to trajectory distinguishing. In contrast to the conventional notion of classical reliability, which is evaluated using probabilistic measurements of binary logical variables, quantum reliability is grounded in the quantum probability amplitude or wave function. This research provides a universal framework for reliability theory encompassing both classical and quantum devices. It offers a new perspective on quantum engineering by elucidating how intensely the real quantum process that a device undergoes influences its performance.

[Clinical outcomes of anterior tibial tendon transfer combined with supramalleolar osteotomy in stage 3b of varus ankle osteoarthritis].

To investigate the clinical and radiographic results of anterior tibial tendon (ATT) transfer combined with supramalleolar osteotomy in stage 3b of varus ankle osteoarthritis. Totally 13 patients with stage 3b of varus ankle osteoarthritis who received ATT transfer combined with supramalleolar osteotomy in Beijing Tongren Hospital from January 2018 to May 2021 were recruited. There were 6 males and 7 females with a mean age of (57.8±9.3) years. The overall evaluations included the preoperatively and postoperatively radiographic alignments, visual analog scale (VAS) score, and the American Orthopaedic Foot & Ankle Society (AOFAS) clinical ankle-hindfoot scale. The mean follow-up period was (33.5±13.4) months. The tibial articular surface (TAS), talar tilt (TT), and foot and ankle offset (FAO) changed from 83.3°±2.4° to 92.8°±1.7°, 12.3°±4.5° to 7.0°±4.7°, and -7.4%±2.8% to -0.7%±2.2% after the operation, respectively (all P<0.001). The AOFAS and VAS score improved significantly at the final follow-up when compared with those before the operation (both P<0.001). It indicated that ATT transfer after supramalleolar osteotomy can achieve good clinical and radiographic results in the treatment of varus ankle arthritis in Takakura stage 3b.

[Changes of brain network in patients with insomnia following radiotherapy for cervical cancer and their correlation with IT-TMS treatment efficacy: a graph-theory analysis].

OBJECTIVE: To analyze the changes of brain small-world and node function network properties in patients with insomnia following radiotherapy for cervical cancer based on graph theory analysis and explore the correlation between functional networks and the clinical efficacy of individual-target transcranial magnetic stimulation (IT-TMS) for treatment of insomnia. METHODS: The resting state functional magnetic resonance imaging (rs-fMRI) data were collected from 30 patients with insomnia following radiotherapy for cervical cancer and 30 matched healthy individuals. All the patients received accelerated intelligent neuromodulation TMS therapy. Using graph theory analysis and GRETNA software, the functional connectivity matrices were constructed and the attribute features were extracted. The scores on the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS) of the participants were collected before and after IT-TMS, and the correlation between improvement in insomnia and the functional network was investigated. RESULTS: The two groups matched for age, gender, and education level (P>0.05) showed significant differences in PSQI, ISI, SAS and SDS scores (P<0.05). Both groups showed attributes of the small-world network. Compared with the healthy individuals, the patients showed significantly decreased σ, EI, Cp and Lp (P<0.05) and increased Eg (P<0.05) at baseline, which, along with insomnia symptoms, were all improved after IT-TMS treatment. The patients showed reduced functional connections of the node network at follow-up compared with the baseline, and the low functional connectivity between the right insula and left superior frontal gyrus was correlated with the improvement of ISI scores. CONCLUSION: The patients with insomnia following radiotherapy for cervical cancer have impaired information integration ability of the brain network, IT-TMS can significantly improve insomnia symptoms by reducing the hyperconnectivity between the default mode network and the salience network.

[Comparation of outcomes of iliac crest bone graft and accessory navicular bone graft in the Cotton osteotomy for pediatric and adolescent flexible flatfoot].

Objective: To compare the outcomes between iliac crest and accessory navicular as different bone grafts in the Cotton osteotomy in the treatment of pediatric flexible flatfoot deformity. Methods: A retrospective cohort study. The clinical data of pediatric flexible flatfoot patients with symptomatic accessory navicular received operations from July 2018 to March 2022 in Beijing Tongren Hospital were retrospectively analyzed. All the patients were treated with Cotton osteotomy. According to the different sources of bone grafting in Cotton osteotomy, the patients were divided into iliac crest group and accessory navicular group. There were 12 patients (19 feet) in iliac crest group, including 9 males and 3 females with a median age M(Q1, Q3) of 11(11, 12) years and were followed-up for 36(6, 48) months. There were 9 patients (16 feet) in accessory navicular group, including 6 males and 3 females, with a median age M(Q1, Q3) of 11(11, 11) years and were followed-up for 12(6, 17) months. Radiographic evaluations were reviewed and compared between the two groups before surgical treatment and at final follow-up, included talo-1st metatarsal angle (T1MT), talonavicular coverage angle (TNCA), talocalcaneal angle (TCA) in weight bearing anteroposterior view, and Meary angle, calcaneal Pitch angle, Kite angle, cuneiform articular angle (CAA) in weight bearing lateral view, and hindfoot alignment angle (HAA) in calcaneal long axial view. Functional scores included American Orthopedic Foot and Ankle Society (AOFAS), visual analog scale (VAS), and Maryland scores were recorded and compared before and after the operation. The complications were also recorded. Results: Total of 21 patients were successfully followed in this study. The radiographic measurements in the two groups, such as T1MT, TNCA, Meary angle, Pitch angle, Kite angle, CAA, HAA, were all significantly improved at the last follow-up when compared with those before the surgery (all P<0.05); and the AOFAS, VAS, Maryland scores in both groups were all improved after the surgery (all P<0.05). There was a significant difference in CAA alteration (∆CAA) after the operation between the two groups, the ∆CAA in iliac crest group and the accessory navicular group was 6.0°±2.6° and 4.3°±1.3°, respectively (P=0.017). There was no significant differences in the improvement of other radiographic measurements between the two groups (all P>0.05). All the patients had a successful bone union. Two patients had donor site pain in the iliac crest group and were treated conservatively. Conclusion: Compared with iliac crest bone graft, accessory navicular bone graft could achieve comparable outcomes in radiographic measurements and functional scores in the treatment of pediatric flexible flatfoot with accessory navicular pain.
