[Functional analysis of laparoscopic intracorporeal Xing's neobladder in long-term follow-up].

Evaluation of neobladder function in patients with long-term survival and no recurrence after laparoscopic radical cystectomy and intracorporeal Xing's neobladder. The clinical data of laparoscopic radical cystectomy and intracorporeal Xing's neobladder in long-term survival patients with bladder cancer treated in Beijing Chaoyang Hospital from July 2013 to July 2018 were analyzed retrospectively. All 17 patients underwent the surgery by the same surgical team, including 15 males and 2 females, whose mean age at the time of operation was (55.9±7.6) years. Thepostoperative urinary function and renal function were summarized. All operations were successfully completed. The mean operative time was (340±62) min. All patients were followed up for a long time, with a median follow-up time of 80(70, 96) months, Urinary continence was achieved in 17 (100%)casesduring the day and 13 (76.5%) cases at night, with a median bladder volume of 350 (200, 400) ml. All patients had good urinary control after surgery, and no hydronephrosis or creatinine increase was found in reexamination.After the application of Xing's neobladder operation, the patient maintained acceptable urinary control status after the operation, and the long-term follow-up effect was satisfactory.

[Expert consensus on standardized clinical applications of minimally invasive tooth extraction techniques].

Tooth extraction is a common and widely employed therapeutic procedure in oral and maxillofacial surgery. Minimally invasive tooth extraction can reduce both physical and psychological trauma to the patients, and is widely recommended as a first-line clinical treatment. But currently no guidelines or consensus has been available to provide a systematic introduction of minimally invasive tooth extraction to guide the clinical practices. To address this issue, this consensus, based on a comprehensive literature review and clinical experiences of experts, systematically summarizes the indications, target patients, and contraindications of minimally invasive tooth extraction, the overall workflow of this procedure (preoperative preparation, surgical steps, postoperative management, postoperative instructions, medications, and follow-up), and its common postoperative complications to provide a comprehensive guidance for clinical application of this technique.

Prevalence and predictors of school truancy among adolescents in Sierra Leone: evidence from the 2017 Global School-based Health Survey.

BACKGROUND: School truancy, deliberately skipping school without permission, is a complex issue with far-reaching consequences for individual students, education systems, and entire communities. While this phenomenon is not unique to Sierra Leone, the specific context of the post-conflict nation raises concerns about its potential impact on the country's fragile rebuilding process. This study examines the prevalence and predictors of school truancy among adolescents in Sierra Leone. METHODS: The study analysed the cross-sectional 2017 Global School-based Health Survey (GSHS) data in Sierra Leone, a nationally representative survey conducted among adolescents aged 10-19 years using a multistage sampling methodology. A weighted sample of 2,769 adolescents in Sierra Leone was included in the study. A multivariable binary regression analysis was used to examine the predictors of school truancy among adolescents. The regression results were presented using an adjusted odds ratio (AOR) with 95% confidence intervals (CI). RESULTS: The prevalence of school truancy was 35% among adolescents in Sierra Leone. Adolescents who use alcohol (AOR = 2.28, 95% CI = 1.45, 3.58) and who have ever had sexual intercourse (AOR = 1.67, 95% CI = 1.10, 2.53) had higher odds of being associated with school truancy. Adolescents who planned suicide (AOR = 0.58, 95% CI = 0.36, 0.93) and whose parents did not intrude on their privacy (AOR = 0.66, 95% CI = 0.45, 0.97) had lower odds of being associated with school truancy. CONCLUSION: School truancy is a critical issue in Sierra Leone, demanding multi-pronged interventions at policy and practice levels. Addressing underlying causes like alcohol use, sexual behaviour, planned suicide, and parent's intrusion of privacy is crucial. Key strategies include fostering positive school environments, providing mental health support, and improving parent-child communication.

Complication of Intrapulmonary Cavitary Lesions after COVID-19 Finally Proved as Pulmonary Aspergillosis.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus type 2, which is characterized by high infectiousness and diverse clinical manifestations. They are more likely to become critical in people who have underlying diseases or are immunocompromised. In the daunting task of treating patients with COVID-19, those with comorbid fungal infections are susceptible to underdiagnosis or misdiagnosis, which can ultimately lead to increased morbidity and mortality in this group of patients. We report a case of intrapulmonary cavitary lesions after COVID-19, which was eventually diagnosed as pulmonary aspergillosis (PA) by metagenomic Next Generation Sequencing (mNGS) to improve our understanding of the disease. METHODS: Appropriate laboratory tests, chest computed tomography (CT), mNGS, and serologic tests were performed for diagnosis. RESULTS: Laboratory tests showed Glactomannan (GM) of 1.41, multiple cavitary lesions in both lungs on chest CT and the presence of aspergillus infection was confirmed by sputum sent for mNGS. CONCLUSIONS: In the case of cavitary lesions after COVID-19, we should be alert to the possibility of combined fungi and should promptly perform mNGS to clarify whether there is a combination of specific pathogenic fungal infections.

Exploring the drivers of unmet need for contraception among adolescents and young women in Sierra Leone. a cross-sectional study.

BACKGROUND: Sierra Leone grapples with a concerning reality: a high unmet need for contraception among adolescents and young women (AYW). This translates to a multitude of unintended pregnancies, jeopardising their health, education, and overall life trajectory. To effectively address this challenge, we aim to examine the factors associated with the unmet need for contraception among AYW in Sierra Leone. METHODS: The study analysed the 2019 Sierra Leone Demographic and Health Survey data. A total of 1,796 married and cohabiting AYW aged 15 to 24 years, representing the nationally representative sample, comprised the study. A multivariable binary regression analysis was used to explore the drivers of unmet needs for contraception. The regression results were presented using an adjusted odds ratio (AOR) with 95% confidence intervals (CI). RESULTS: The study found that 29% of Sierra Leonean AYW had an unmet need for contraception. AYW with three or more births(AOR = 6.80, 95% CI = 3.97, 11.65), two births (AOR = 4.11, 95% CI = 2.50, 6.76), one birth (AOR = 4.40, 95% CI = 2.81, 6.88), heard family planning on TV last few months (AOR = 1.94, 95% CI = 0.98, 3.83), and are cohabiting (AOR = 1.88, 95% CI = 1.29, 2.75) had higher odds of unmet need for contraception. AYW who read the newspaper or magazine at least once a week (AOR = 0.11, 95% CI = 0.01, 1.10) had lower odds of unmet need for contraception. CONCLUSIONS: The study found a high unmet need among AYW in Sierra Leone, which indicates a significant gap between desired and actual contraceptive use, leading to unintended pregnancies and potentially adverse health and socio-economic consequences. Parity, media exposure and cohabitation were associated with a higher unmet need for contraception and newspaper/magazine readership was associated with a lower unmet need for contraception. The study highlights the need to increase access to affordable and diverse contraceptive options, especially in rural areas. Expand educational campaigns beyond TV to include print media and community-based interventions. Provide AYWs with knowledge and authority to make well-informed decisions around their sexual and reproductive well-being.

The state of mental health among Ebola virus disease survivors through a cross-sectional study in Sierra Leone.

BACKGROUND: The West African Ebola virus disease (EVD) epidemic resulted in >28 000 disease cases and >11 000 fatalities. The unprecedented number of survivors from this epidemic has raised questions about the long-term mental health impacts of EVD survivorship and the capacity to meet these needs. OBJECTIVES: Assess the frequency and factors associated with mental health consequences of EVD survivorship in Sierra Leone. METHODS: A cross-sectional study of 595 EVD survivors and 403 close contacts (n=998) from Sierra Leone assessed via in-person survey between November 2021 and March 2022. The assessment included validated mental health screening tools (Patient Health Questionnaire-9, PTSD Checklist-5, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test-20) to indicate the presence/absence of disorder. The frequency of each disorder and factors associated with each disorder were assessed. FINDINGS: EVD-associated post-traumatic stress disorder (PTSD) was reported by 45.7% (n=257) of EVD survivors. Moreover, 3.9% (n=22) and 12.0% (n=67) of EVD survivors reported major depression (MD) and substance use, respectively; all mental health outcomes were higher than baseline rates in the region (PTSD: 6%-16%, MD: 1.1%, substance use: 2.2%). PTSD among EVD survivors was associated with acute EVD duration of ≥21 days (adjusted OR, AOR 2.24, 95% CI 1.16 to 4.43), 35-44 years of age (AOR 3.31, 95% CI 1.33 to 8.24; AOR 2.99, 95% CI 1.09 to 8.24) and residential mobility (AOR 4.16, 95% CI 2.35 to 7.35). CONCLUSIONS: Concerningly, the levels of mental health disorders among EVD survivors in Sierra Leone remained elevated 6-8 years after recovery. CLINICAL IMPLICATIONS: Results can be used to inform policy efforts and target resources to address mental health in EVD survivors.

Alcohol use among in-school adolescents in Sierra Leone.

OBJECTIVE: To examine the prevalence of alcohol use and its associated factors among in-school adolescents in Sierra Leone. DESIGN: Data for the study was sourced from the 2017 Sierra Leone Global School-Based Student Health Survey, a nationally representative survey conducted among in-school adolescents aged 10-19 years using a multistage sampling methodology. Percentages were used to present the prevalence of alcohol use among in-school adolescents. Multivariable binary logistic regression analysis was performed to examine the factors associated with alcohol use among in-school adolescents. The results were presented using adjusted odds ratios (aOR) with their respective 95% confidence interval (CI). SETTING: Sierra Leone. PARTICIPANTS: A weighted sample of 1730 in-school adolescents in Sierra Leone. OUTCOME MEASURE: Current alcohol use. RESULTS: The prevalence of alcohol use among in-school adolescents was 10.7% (7.3, 15.3). In-school adolescents in senior secondary schools were more likely to use alcohol compared with those in junior secondary school (aOR=2.13; 95% CI 1.37, 3.30). The odds of alcohol use was higher among in-school adolescents who were truant at school relative to those who were not (aOR=2.24; 95% CI 1.54, 3.26). Also, in-school adolescents who were bullied (aOR=1.85; 95% CI 1.24, 2.76), ever engaged in sexual intercourse (aOR=2.06; 95% CI 1.39, 3.06), and used marijuana (aOR=3.36; 95% CI 1.72, 6.53) were more likely to use alcohol compared with those who were not. However, in-school adolescents who reported that their parents understood their problems (aOR=0.52; 95% CI 0.33, 0.82) had a lower likelihood of consuming alcohol. CONCLUSION: Our study has shown that alcohol use is prevalent among in-school adolescents in Sierra Leone. Grade level, experiences of being bullied, history of sexual intercourse, truancy at school, and previous use of marijuana were the factors influencing alcohol use among in-school adolescents. The findings emphasise the necessity of creating school-based health interventions in Sierra Leone that can effectively identify in-school adolescents potentially vulnerable to alcohol-related issues. Also, existing policies and programmes aimed at reducing alcohol use among in-school adolescents need to be strengthened.

Prevalence and predictors of lifetime amphetamine use among in-school adolescents in Sierra Leone.

OBJECTIVE: This study examined the prevalence of amphetamine use and its associated factors among in-school adolescents in Sierra Leone. DESIGN: Data for the study was sourced from the 2017 Sierra Leone Global School-based Health Survey. Percentages with confidence intervals (CIs) were used to present the prevalence of amphetamine use among in-school adolescents. A multivariable binary logistic regression analysis was employed to examine the factors associated with amphetamine use. The results were presented using adjusted odds ratios (aORs) with 95% CIs. SETTING: Sierra Leone. PARTICIPANTS: A weighted sample of 1,314 in-school adolescents in Sierra Leone. OUTCOME MEASURE: Lifetime amphetamine use. RESULTS: The prevalence of amphetamine use was 6.1% (3.9%-9.5%). In-school adolescents who planned suicide were more likely to use amphetamine compared with those who did not (aOR 2.54; 95% CI 1.02 to 6.31). Also, the odds of amphetamine use were higher among in-school adolescents who received support from their peers (aOR 3.19, 95% CI 1.71 to 5.96), consumed alcohol (aOR 4.85, 95% CI 2.61 to 9.03), and those who had previously used marijuana (aOR 13.31, 95% CI 6.61 to 28.78) compared with those who did not receive any support, never consumed alcohol, and never used marijuana, respectively. CONCLUSION: Amphetamine use is prevalent among in-school adolescents in Sierra Leone. There is a need to implement comprehensive public health policies that extend beyond school-based psychobehavioural therapies. These policies should specifically address the considerable risk factors associated with amphetamine use among in-school adolescents in Sierra Leone.

Off the Shelf Multibranched Endograft for Thoraco-Abdominal and Pararenal Abdominal Aortic Aneurysms: a Prospective, Single Centre Study of the G-Branch Endograft.

OBJECTIVE: To investigate outcomes of a novel, off the shelf multibranched endovascular stent graft for the treatment of thoraco-abdominal aortic aneurysm (TAAA) and pararenal abdominal aortic aneurysm (PAAA). METHODS: A prospective, single centre study including 15 patients (mean age, 63.4 ± 10.7 years; 13 male) with TAAA or PAAA treated from October 2019 to March 2021 with a G-Branch endograft (Lifetech Scientific, Shenzhen, China) featuring a mixed multibranch design with two inner and two outer branches for reconstruction of the visceral and bilateral renal arteries, respectively. Follow up assessments were scheduled before discharge and at 30 days, six and 12 months after the index procedure. Annual telephone interviews were performed beyond the initial 12 months. The Kaplan-Meier method was used to estimate cumulative mortality and morbidity rates after endovascular repair. RESULTS: Technical success was achieved in all 15 patients. Nine patients (60%) had TAAA and six (40%) had PAAA (mean maximum aneurysm diameter, 73.7 ± 15.8 mm). The median follow up was 31.4 months (range, 10.1 - 44.0 months). At 30 days, there was no death and 7% morbidity (one case of temporary spinal cord ischaemia on Day 4). At one year, the mortality rate was 7% (one death from stroke at 10 months) and morbidity was 13% (one other case of renal function decline at six months). There were no aneurysm dilatations, re-interventions, or access related complications, and two (13%) persistent type II endoleaks. The one year primary branch patency rate was 100% for the four renovisceral arteries in all 13 patients who underwent computed tomography examinations. One patient died of hepatocellular carcinoma 29 months post-operatively, resulting in an estimated three year mortality rate of 13%. CONCLUSION: The G-Branch endograft yielded high technical success with good early and midterm outcomes for the treatment of TAAA and PAAA. A large multicentre study is warranted.

Stigmatization of Ebola virus disease survivors in 2022: A cross-sectional study of survivors in Sierra Leone.

BACKGROUND: Evidence has demonstrated a high proportion of Ebola virus disease (EVD) survivors experienced stigma due to the disease. This study sought to understand the longer-term effects of stigma encountered by survivors of the 2014-2016 EVD epidemic living in Sierra Leone. METHODS: This was a cross-sectional study of 595 EVD survivors and 403 close contacts (n = 998) from Sierra Leone. Assessments were conducted using a three-part survey between November 2021 to March 2022. We explored the socio-demographic factors associated with stigma experienced by EVD survivors. FINDINGS: 50·6 % (n = 301) of EVD survivors reported that they continued to experience at least one aspect of stigma. Females were disproportionately affected by stigma, with 45·2 % of females reporting isolation from friends and family compared to 33·9 % of men (p = 0·005). Multivariable logistic regression models revealed those aged 40-44, living rurally, and reporting an acute infection longer than seven days was associated with EVD-related stigma at the time of survey. INTERPRETATION: This study demonstrates stigma is still prevalent among people who survived EVD in 2022. It also identified socio-demographic factors associated with stigma that can be used for targeting interventions. Importantly, this highlights the continued need for EVD survivors to access mental healthcare and social support systems well after disease recovery.

Lateral retraction could achieve better early postoperative knee function than patellar eversion in total knee arthroplasty: a systematic review and meta-analysis.

OBJECTIVE: Comparisons between patellar eversion (PE) and lateral retraction (LR) in total knee arthroplasty (TKA) are still inconclusive. To determine the most suitable procedure, we aimed to evaluate the safety and efficacy of PE and LR in TKA in this meta-analysis. MATERIALS AND METHODS: This meta-analysis complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Web-based literature databases, including WANFANG, VIP, CNKI, the Cochrane Library, Embase, and PubMed, were utilized to conduct a comprehensive literature search for studies published until June 2022 that compared PE with LR in primary TKA. The quality of the selected randomized controlled trials (RCTs) was evaluated using guidelines of the Cochrane Reviews Handbook 5.0.2. RESULTS: A total of 10 RCTs, including 782 patients and 823 TKAs, were selected in this meta-analysis. Our results showed that using LR improved postoperative knee extensor function and range of motion (ROM). In addition, PE and LR resulted in similar clinical benefits in terms of Knee Society Function score, pain, length of hospital stay, Insall-Salvati ratio, the occurrence of patella baja, and complications related to the operation. CONCLUSIONS: Existing evidence suggested that using LR in TKA improved early postoperative knee function. Similar clinical and radiographic outcomes were obtained 1 year after the procedures were performed. Based on these findings, we recommended the use of LR in TKA. However, studies with large sample sizes are needed to validate these findings.

Organizing Pneumonia with NGS False-Positive Imaging Resembling Tuberculosis: a Case Report.

BACKGROUND: Organizing pneumonia (OP) is a pathologic concept characterized by the formation of granulation tissue from fibroblasts, myofibroblasts, collagen, and fibrotic exudate in the respiratory fine bronchi, alveolar ducts, and alveoli. The clinical imaging of mechanized pneumonia is variable, and histopathological examination is required to clarify the nature of the lesion when imaging is atypical. We report a case of OP with imaging resem-blance to pulmonary tuberculosis and false-positive next-generation sequencing (NGS), which was first misdiag-nosed as pulmonary tuberculosis. METHODS: Appropriate laboratory tests, alveolar lavage fluid NGS, chest CT, bronchoscopy, percutaneous lung puncture, pathology. RESULTS: Chest CT showed a nodular high-density shadow in the lower lobe of the right lung. According to the chest CT, bronchoalveolar lavage was performed in the dorsal segment of the right lower lobe of the lung. NGS of lavage fluid: the sequence number of Moraxella osseae was 1,423; the sequence number of Prevotella melanogaster was 1,129. Based on lung histopathology, fibrous emboli and necrotic material were seen in the alveolar lumen, and the final diagnosis of the OP was confirmed. CONCLUSIONS: It should be noted that physicians should not blindly believe the NGS result report. When the diagnosis is not clear and anti-infection treatment is ineffective, lung tissue should be obtained promptly for pathological examination to obtain pathological evidence to differentiate from misdiagnosed diseases.

Rare Co-Infection of the Lungs with EBV and Pneumocystis Carinii in a Patient with Kidney Cancer: a Case Report.

BACKGROUND: Epstein-Barr virus (EBV) is the primary agent of infectious mononucleosis, lymphoma, and naso-pharyngeal carcinoma, but rarely involves the lungs. Pneumocystis carinii is commonly found in patients with HIV infection and is not pathogenic when the host is healthy, but opportunistic infections can occur when the body is immunocompromised, causing pneumocystis pneumonia (PCP). It is rare for both diseases to occur in the lungs of the same patient. METHODS: Next-generation sequencing (NGS), laboratory examination, chest CT scan, electronic bronchoscopy, and pathogenetic examination were used in this study. RESULTS: Laboratory tests showed (1-3)-ß-D-glucan of 889.47 pg/mL, negative human immunodeficiency virus (HIV) antibody, and negative Aspergillus immunological test. Chest CT showed multiple high-density shadows in both lungs, and EBV infection combined with Pneumocystis carinii pneumonia was confirmed by bronchoscopic biopsy and NGS examination. CONCLUSIONS: Elevated serum (1-3)-ß-D-glucan is not a specific index for infectious diseases. Bronchoscopy and the NGS has high specificity in pathogen detection of infectious diseases.

D-Dimer and Procalcitonin Improve the Sensitivity of BAP-65 Score in Predicting AECOPD Patients Admission to ICU.

BACKGROUND: The study aimed at investigating the effectiveness of the BAP-65 score combined with D-dimer and procalcitonin (PCT) in predicting admission of acute exacerbation chronic obstructive pulmonary disease (AECOPD) patients to the intensive care unit (ICU). METHODS: We conducted a retrospective study. We analyzed data from 369 patients over the age of 40 years ad-mitted to our hospital with AECOPD. All patients received blood routine measurements and BAP-65 score calculation on admission. Receiver operating characteristic curves (ROC) were used to assess the sensitivity and specificity of D-dimer, PCT, and BAP-65 scores and combined metrics in predicting the risk of admissions to the ICU of AECOPD patients. RESULTS: We found that the percentage of patients with AECOPD admitted to the ICU was 32.25% (119/369). The area under the curve (AUC) of D-dimer, PCT, and BAP-65 score in individually predicting the probability of entering the ICU of AECOPD patients were 0.74 (95% CI 0.68 - 0.80), 0.83 (95% CI 0.78 - 0.88), and 0.72 (95% CI 0.66 - 0.79), respectively. The sensitivities of D-dimer, PCT, and BAP-65 score were 0.51, 0.65, and 0.52, respectively. The specificities of D-dimer, PCT, and BAP-65 score were 0.90, 0.91, and 0.92, respectively. The AUC of D-dimer and PCT combined with BAP-65 score was 0.90 (95% CI 0.86 - 0.94), the sensitivity and specificity were 0.90 and 0.80, respectively. CONCLUSIONS: D-dimer and procalcitonin improve the sensitivity of the BAP-65 score in predicting the probability of AECOPD patients entering the ICU while having a good specificity.

Procalcitonin (PCT) Improves the Accuracy and Sensitivity of CURB-65 Score in Predicting CAP Patients Admission to ICU.

BACKGROUND: The CURB-65 scoring system is a simple tool for assessment and prognosis prediction for community-acquired pneumonia (CAP) patients. However, the variations in the performance of CURB-65 in young and elderly patients, underestimation, or overestimation of the severity have often been reported. It is worth noting that the application of biomarkers is helpful for improving the accuracy of the scoring system. In recent years, more and more reports and studies paid attention to procalcitonin (PCT) in respiratory infectious diseases, and its clinical value has attracted increasing attention. The study aimed at investigating the effectiveness of the CURB-65 score combined with PCT in predicting admission of CAP patients to intensive care units (ICU). METHODS: We conducted a retrospective study. We analyzed data from 520 non-immune individuals over the age of 18 in this study. All patients received blood indicators measurement and CURB-65 score calculation on admission. The primary outcome used to assess the probability of a CAP patient was who would get a bed in general ward or ICU. Receiver operating characteristic curves (ROC) were used to evaluate the sensitivity and specificity of the CURB-65 model and PCT combined CURB-65 augmented model in predicting the main outcomes. RESULTS: After analyzing the data from 520 patients, we found that the probability of entering the ICU was 22.1% (115/520). The AUC of Combination 1 (PCT&CURB-65 scores), Combination 2 (WBC&CURB-65 scores), Combination 3 (hs-CRP&CURB-65 scores) and Combination 4 (D-dimer&CURB-65 scores) for predicting CAP patients entering the ICU was 0.92 (95% CI 0.88 - 0.95), 0.91 (95% CI 0.87 - 0.94), 0.89 (95% CI 0.85 - 0.92), and 0.90 (95% CI 0.87 - 0.94), respectively, with statistically significant differences (p = 0.00); the sensitivities were 0.83, 0.82, 0.77 and 0.77, respectively, and the specificities were 0.92, 0.84, 0.90 and 0.91, respectively. PCT was superior to other indexes to improve the sensitivity and specificity of the CURB-65 score. CONCLUSIONS: Procalcitonin improves the accuracy and sensitivity of the CURB-65 score in predicting the probability of CAP patients entering the ICU, and PCT was superior to other indexes to improve the sensitivity and specificity of the CURB-65 score.

A New Prediction Model for Prolonged Hospitalization in Adult Community-Acquired Pneumonia (CAP) Patients.

BACKGROUND: As a serious and common out-of-hospital infectious disease, community-acquired pneumonia (CAP) ranks among the leading causes of death in both developing and developed countries. In recent years, the increasing incidence of CAP has led to an increase in the number of hospitalizations. Although CURB-65 (or CRB-65) and pneumonia severity Index (PSI) scoring systems are widely used in CAP prognostic scoring systems, each score had some limitations in predicting whether patients with CAP would require prolonged hospitalization. The aim of this study was to analyze serum inflammatory biomarkers combined with age to establish a novel predictive model for predicting prolonged hospitalization in patients with CAP. METHODS: In a retrospective study, serum inflammatory biomarkers were collected from all enrolled CAP patients, including white blood cell count (WBC), high-sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), D-dimer, procalcitonin (PCT), fibrinogen (FIB), and ICU treatment. Length of hospital stay and age were also recorded. The 75th percentile of length of stay in the enrolled population was defined as long hospitalization over time, and the primary predictor of outcome was prolonged hospitalization. Univariate analysis and binary logistic regression analysis were used to explore the independent risk factors which could be components of a new predicting model for prolonged hospitalization in CAP patients. ROC curves were used to evaluate the sensitivity and specificity of the new model, which consisted of the combination of all independent risk factors in predicting the main outcomes. RESULTS: The results showed that among 364 patients with CAP, 85 had extended hospitalization (85/364). Further analysis showed that age, white blood cell, fibrinogen, and high-sensitivity C-reactive protein were independent risk factors for extended hospitalization in patients with CAP. Finally, the AUC of the ROC curve of the new prediction model (the joint model consists of age, WBC, FIB, and hs-CRP) was 0.93 (95% CI 0.90 - 0.96), and the sensitivity and specificity were 87.1% and 87.8%, respectively. CONCLUSIONS: Serum inflammatory biomarkers combined age have high specificity and sensitivity in predicting prolonged hospitalization in adult CAP patients.

Carcinoembryonic Antigen Elevation in Broncholithiasis Patients Initially Misdiagnosed as Lung Cancer: a Case Report.

BACKGROUND: We report a case of broncholithiasis with recurrent pulmonary infection accompanied by blood in the sputum, which was initially misdiagnosed as lung cancer after laboratory examination indicating elevated carcinoembryonic antigen. METHODS: Laboratory examination, enhanced chest CT scan, electronic bronchoscopy, and ultra-thin bronchoscopy were performed to diagnose broncholithiasis. RESULTS: Carcinoembryonic antigen levels were elevated. Chest CT scan showed dense nodules and calcification in the middle lobe of the right lung. Ultrathin bronchoscopy demonstrates calcification of the distal bronchus of the lateral middle lobe of the right lung. The symptoms were relieved after the removal of the calculi by electronic bronchoscopy. CONCLUSIONS: It is necessary to pay attention to the calcification of the trachea and the differential diagnosis of lung cancer, especially when the level of carcinoembryonic antigen is increased.

The introduced strain Mesorhizobium ciceri USDA 3378 is more competitive than an indigenous strain in nodulation of chickpea in newly introduced areas of China.

The present study aimed to compare the competitive advantage of two chickpea nodulating rhizobia strains (an indigenous strain Mesorhizobium muleiense CCBAU 83963T and an introduced strain Mesorhizobium ciceri USDA 3378) in different soils originated from new chickpea cultivation areas of China. The results showed that USDA 3378 had a significant competitive advantage in nodulation, with nodulation occupation rates ranging from 84·6% to 100% in all the sampled soils. According to the efficiency of symbiosis under single inoculation, chickpea plants inoculated with USDA 3378 showed better symbiotic performance based on the plant dry weight, leaf chlorophyll content and nodule numbers. The chickpea plants inoculated with USDA 3378 formed nodules about 2 days earlier than those inoculated with CCBAU 83963T . The higher growth in media and the stronger adsorption on chickpea roots of USDA 3378 when mixed with CCBAU 83963T may explain why USDA 3378 shows a competitive advantage. The results from this study will contribute towards the development of effective chickpea rhizobial inoculants for soil conditioning and more environmentally friendly production of chickpeas in China.

[Clinical study of digital six-axis external fixation frame based on CT data for tibiofibular fractures].

Objective: To investigate the clinical effect of applying the digital six-axis external fixation frame based on CT data in the treatment of tibiofibular fractures. Methods: The clinical data of 43 patients with tibiofibular fractures treated by the self-developed digital six-axis external fixation frame based on CT data at Integrated Orthopedic Department of Traditional Chinese Medicine (TCM) and Western Medicine,HongHui Hospital from January 2018 to January 2021 were retrospective analysis.There were 27 males and 16 females,aged (36.0±9.4) years(range:25 to 50 years).AO classification:15 cases of 42A,11 cases of 42B, and 17 cases of 42C.There were 7 open fractures and Gustilo fracture classification:2 cases of type Ⅰ,4 cases of type Ⅱ,and 1 case of type Ⅲ.The two or three plane rings were connected with six connecting rods to form a complete six-axis external fixation frame,and the distal and proximal fracture blocks were connected to the distal and proximal rings by fixation pins,and the lengths of the six connecting rods needed to be adjusted were calculated by using the supporting software according to the CT data after surgery,and then the lengths of the connecting rods were adjusted one by one to complete the reduction of the fracture. The reduction accuracy of this six-axis external fixation brace was evaluated by measuring postoperative radiographs; postoperative recovery and complications were collected,the time of brace removal was recorded,and the function of the affected limb was evaluated according to the Johner-Wruhs score at the final follow-up. Results: Postoperative radiographs showed that all patients achieved satisfactory reduction with lateral displacement(M(IQR)) of 2.3(2.5) mm (range:0.3 to 7.3 mm),anteroposterior displacement of 2.1 (2.4) mm (range:0.3 to 5.7 mm),anteroposterior angulation of 2.5(2.4)°(range:0 to 5°),internal and external angulation of 2.1(1.5)°(range:0 to 4°), and no significant internal or external rotational deformity was detected on the exterior.On the second postoperative day,all patients were able to walk with partial weight-bearing on crutches. All 43 patients were followed up for more than 6 months,with a follow-up period of (33.3±7.3) weeks (range:24 to 42 weeks).The external fixation frame was removed after the fracture healed.The external frame was removed at 20(3)weeks (range:18 to 25 weeks) postoperatively. Up to the final follow up, no secondary fracture occurred in any of them.The Johner-Wruhs score of the affected limb at the last follow-up was excellent in 39 cases and good in 4 cases. Conclusion: The digital six-axis external fixator based on CT data for tibiofibular fractures has the advantages of precise reduction,firm fixation,simple operation,rapid fracture healing,and minimal trauma, which is a minimally invasive method for treating tibiofibular fractures,especially suitable for patients with poor skin and soft tissue conditions such as open injuries.
