Bifid triple viable preparation combined with enteral nutrition as a supportive treatment for acute ischemic stroke: a systematic review and meta-analysis.

The benefits and risks of bifid triple viable preparations in patients with acute ischemic stroke (AIS) are still controversial. This study aimed to assess the efficacy and safety of bifid triple viable preparations in combination with enteral nutrition for the management of AIS. Eight public databases including China National Knowledge Infrastructure, China Biology Medicine, VIP, WanFang, EBSCO, PubMed, Cochrane Library, and Web of Science were searched for relevant clinical literature, published through January 2024. These data were then used in the present meta-analysis. A total of 15 studies involving 1,544 patients were included in the meta-analysis. In terms of nutritional status, the results showed that compared with enteral nutrition alone, the bifid triple viable preparation combination group increased the levels of total protein (mean difference [MD], 5.53; 95%confidence interval [CI], 1.94-9.12; p = 0.003), albumin (MD, 4.01; 95%CI, 2.96-5.06; p < 0.00001), prealbumin (MD, 23.08; 95%CI, 16.22-29.95; p < 0.00001), hemoglobin (MD, 9.31; 95%CI, 6.34-12.27; p < 0.00001), and transferrin (MD, 0.64; 95%CI, 0.23-1.05; p = 0.002); in terms of neurological function, it improved the Glasgow Coma Scale (MD, 2.09; 95%CI, 0.69-3.49; p = 0.003), National Institute of Health Stroke Scale (MD, -3.07; 95%CI, -3.73 to -2.40; p < 0.00001), and Neurological Disability Score (MD, -6.68; 95%CI, -7.29 to -6.08; p < 0.00001); in terms of intestinal barrier function, it reduced the levels of endotoxin (MD, -0.55; 95%CI, -0.71 to -0.39; p < 0.00001), D-lactic acid (MD, -3.17; 95%CI, -4.07 to -2.26; p < 0.00001), diamine oxidase (MD, -4.39; 95%CI, -6.20 to -2.57; p < 0.00001), and endothelin (MD, -21.35; 95%CI, -27.86 to -14.83; p < 0.00001); in terms of immune function, it increased the levels of immunoglobulin G (MD, 1.01; 95%CI, 0.20-1.82; p = 0.01) and immunoglobulin M (MD, 0.16; 95%CI, 0.02-0.30; p = 0.03). Additionally, it reduced the incidence of pulmonary infection, vomiting, constipation, and diarrhea, while there were no significant differences in total adverse events, abdominal distension, anorexia, reflux, gastrointestinal bleeding, or electrolyte disturbance. The addition of bifid triple viable preparation to enteral nutrition improved the nutritional status, neurological function, intestinal barrier function, and immune function of patients with AIS, and reduced the risk of infection and gastrointestinal events.

Analysis of the efficacy of left subclavian artery laser in situ fenestration combined with hybrid arch debranching surgery for aortic arch reconstruction in patients with Stanford type A aortic dissection

Objective: To observe the short-and mid-term efficacy of left subclavian artery(LSA) laser in situ fenestration combined with arch debranching surgery for aortic arch reconstruction in patients with Stanford type A aortic dissection aged 60 years and above. Methods: This is a retrospective cohort study. A total of 41 Stanford type A aortic dissection patients aged 60 years and above who received combined surgery in Department of Endovascular Surgery, the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 were retrospectively analyzed. There were 25 males and 16 females, aged (67.3±5.9)years(range: 60 to 75 years). Among them, 19 patients underwent LSA laser in situ fenestration combined with arch debranching surgery(combined surgery group) and 22 patients underwent hybrid aortic arch debranching surgery(non-combined surgery group). Independent sample t test, χ2 test and Fisher exact probability method were used to compare the clinical characteristics of the two groups. Kaplan-Meier method was used for survival analysis, and the 5-year survival rate of the two groups was compared by Log-rank test. Results: Body mass index in the combined operation group was significantly higher than that in the non-combined operation group ((27.1±1.6)kg/m2 vs.(26.9±1.9)kg/m2; t=2.766,P=0.006), and the difference was statistically significant. There was no statistical significance in the comparison of other general data (all P>0.05). The operation time ((320.9±21.7) minutes vs. (326.7±22.5)minutes; t=14.838, P<0.01)) and LSA reconstruction time ((32.6±3.2)minutes vs. (44.7±6.0)minutes; t=46.913, P<0.01) in the combined operation group were significantly shortened, and the difference was statistically significant. The rate of LSA reconstruction in the combined operation group (100% vs. 72.7%; P=0.023) was significantly higher than that in the non-combined operation group, and the difference was statistically significant. There were no significant differences in the incidence of pulmonary infection, unplanned second operation, continuous renal replacement therapy, neurological complications and the in-hospital mortality between the two groups. Compared with the non-combined surgery group, the total complication rate related to LSA reconstruction was significantly lower in the combined surgery group (0 vs. 27.3%; P=0.023). Kaplan-Meier survival analysis showed that there was no difference in 5-year survival rate between the combined operation group and the non-combined operation group (84.2% vs 77.3%; χ2=0.310, P=0.578). Conclusion: Laser in situ fenestration of the LSA combined with arch debranching surgery to reconstruct the aortic arch can significantly shorten the operation and LSA reconstruction time in patients with Stanford type A aortic dissection, improve the success rate of LSA reconstruction, and reduce the occurrence rate of LSA reconstruction complications.

Clinical characteristics and risk factors of connective tissue disease complicated with bronchiectasis and pulmonary infection.

The clinical data from 118 CTD patients with bronchiectasis were collected and categorized into two groups: pulmonary infection present (n = 67) and absent (n = 51), for comparative analysis of characteristics and risk factors. Then, we analyzed and compared their demographics, disease characteristics, and risk factors for infection. Among the whole cohort (n = 118), the incidence of pulmonary infections was 56.78%. The occurrence of rheumatoid arthritis, systemic lupus erythematosus, and vasculitis was found to be associated with an increased risk of pulmonary infection. Sputum culture identified Pseudomonas aeruginosa and Klebsiella pneumoniae as the predominant pathogens in the infected group. Notably, symptoms such as joint pains (p = 0.018) and morning stiffness (p = 0.017) were significantly more common in the infected group compared to the noninfected group. Moreover, our findings revealed that elevated levels of C-reactive protein and complement C3, along with bronchial expansion observed on high-resolution computed tomography (HRCT), were significant independent factors in the infection group. Conversely, pulmonary interstitial changes identified through HRCT (OR: 0.135, 95% CI: 0.030-0.612, p = 0.009) were significantly associated with the non-infection group. Overall, this study provides valuable insights into managing CTD patients with bronchiectasis, emphasizing early detection and tailored approaches to prevent and treat pulmonary infections for better outcomes.

Effects of acute normovolemic hemodilution and allogeneic blood transfusion on postoperative complications of oral and maxillofacial flap reconstruction: a retrospective study

ObjectivePatients undergoing oral and maxillofacial flap reconstruction often need blood transfusions due to massive blood loss. With the increasing limitations of allogeneic blood transfusion (ABT), doctors are considering acute normovolemic hemodilution (ANH) because of its advantages. By comparing the differences in the (Δ) blood indices and postoperative complications of patients receiving ABT or ANH during the reconstruction and repair of oral and maxillofacial tumor flaps, this study’s purpose was to provide a reference for the clinical application of ANH.MethodsThe clinical data of 276 patients who underwent oral and maxillofacial flap reconstruction from September 25, 2017, to October 11, 2021, in the Department of Oral and Maxillofacial Surgery, Sun Yat-sen Memorial Hospital, were retrospectively analyzed. According to the intraoperative blood transfusion mode, the patients were divided into two groups: ABT and ANH. The differences in the (Δ) blood indices and the incidence of postoperative complications between the groups were analyzed.ResultsAmong the 276 patients who had ANH (124/276) and ABT (152/276), there were no differences in (Δ) Hb, (Δ) PT, or (Δ) FIB (P > 0.05), while (Δ) WBC, (Δ) PLT, (Δ) APTT and (Δ) D-dimer were significantly different (P < 0.05). The blood transfusion method was not an independent factor for flap crisis (P > 0.05). The wound infection probability in patients with high post-PTs was 1.953 times greater than that in patients with low post-PTs (OR = 1.953, 95% CI: 1.232 ∼ 3.095, P = 0.004). A normal or overweight BMI was a protective factor for pulmonary infection, and the incidence of pulmonary infection in these patients was only 0.089 times that of patients with a low BMI (OR = 0.089, 95% CI: 0.017 ∼ 0.462). Moreover, a high ASA grade promoted the occurrence of pulmonary infection (OR = 6.373, 95% CI: 1.681 ∼ 24.163). The blood transfusion mode (B = 0.310, β = 0.360, P < 0.001; ANH: ln hospital stay = 2.20 ± 0.37; ABT: ln hospital stay = 2.54 ± 0.42) improved the length of hospital stay.ConclusionPreoperative and postoperative blood transfusion (Δ) Hb, (Δ) PT, and (Δ) FIB did not differ; (Δ) WBC, (Δ) PLT, (Δ) APTT, and (Δ) D-dimer did differ. There was no difference in the effects of the two blood transfusion methods on flap crisis, incision infection or lung infection after flap reconstruction, but ANH resulted in a 3.65 day shorter average hospital stay than did ABT.

Lung and Airway Disease Caused by E-Cigarette (Vape): A Systematic Review

Vape use is increasing among the youth and there is a catchphrase that vape is the solution to conventional tobacco smoking. Some case reports show the impact of vape use in the form of lung injury. However, there are no studies that definitively determine how many cases and what kind of problems in the lungs and airways can be caused by the use of vape and this is the purpose of our research. This systematic review article used several databases with the keywords "Vape OR E-cigarette" and "Disease." We screened and eliminated articles based on the PEOS framework. The included articles were analyzed for risk of bias using the JBI critical appraisal tool. A total of 16 articles were included and involved 313 patients in this review. Several case reports show the incidence of pulmonary infections in vape users, lung damage (EVALI), respiratory failure, burning throat, and various other events associated with vape use. The duration of vape use also varies before the appearance of the disease and the earliest use duration is six months and the longest is up to years. Vape use poses a risk of lung and airway disease and requires further study to accurately determine the degree of risk of the impact of vape use on lung and airway health. In conclusion, vape circulation vigilance needs to be considered because the impacts can cause health issues and interfere with the achievement of health goals for all.

Evaluating the predictive value of initial lactate/albumin ratios in determining prognosis of sepsis patients.

Sepsis remains a significant clinical challenge owing to its complex pathophysiology and variable prognosis. The early identification of patients at a higher risk of poor outcomes can be crucial for improving treatment strategies. This study aimed to evaluate the predictive value of early serum lactate and albumin levels and the lactate/albumin (L/A) ratio for 28-day prognosis in patients with sepsis. Patients diagnosed with sepsis between January 2021 and December 2022 were evaluated using a retrospective cohort methodology. Inclusion followed the International Consensus on sepsis and septic shock (Sepsis-3) guidelines and patients were selected based on well-defined criteria. Variables such as lactate, albumin, and the L/A ratio were documented within the first 24 hours of admission. Statistical analyses were performed using various tools, including the nonparametric Mann-Whitney U test and receiver operating characteristic curves. A total of 301 patients were divided into the survival (n = 167) and death (n = 134) groups. Notable differences were detected in the incidence of pulmonary infection, shock, lactate, albumin, and the L/A ratio. The L/A ratio was identified as a key predictor with an area under the curve of 0.868, an optimal cutoff value of >0.17, a sensitivity of 56.21%, and a specificity of 94.18%. Significant disparities in mortality rates and survival times were observed for the lactate, albumin, and L/A levels. This study underscores the predictive value of early serum lactate and albumin levels and the L/A ratio for 28-day prognosis in patients with sepsis, with the L/A ratio showing a superior predictive capability. These findings highlight the importance of L/A ratio as a robust and precise marker for evaluating the future clinical course of patients with sepsis, potentially aiding early detection and management.

Graded nutritional interventions in patients with dysphagia after stroke: an assessment of the effectiveness of therapeutic strategies for different swallowing functions

Objective To evaluate the efficacy of graded nutrition intervention strategy in improving patients with different degrees of impaired swallowing function after stroke. Methods According to the way of nursing, the patients were divided into two group. The main outcome measure was Kota swallowing index (WSI) score, and the secondary outcome was complications during the intervention. SF-36 scale was used to evaluate the improvement of quality of life before and intervention. Results The WSI score in the control group was 62.34 ± 10.23 at 1 week after treatment, 70.52 ± 13.45 at 6 weeks after treatment, and 80.48 ± 9.87 at 12 weeks after treatment, while that in the intervention group was 71.45 ± 9.68 at 1 week after treatment, 75.81 ± 11.78 at 6 weeks after treatment, and 84.12 ± 14.32 at 12 weeks after treatment. The WSI scores of the intervention group were significantly higher than those of the control group (t = 5.634, p < 0.001), suggesting better swallowing function of the patients The incidence of pulmonary infection, malnutrition and gastroesophageal reflux in the intervention group was significantly lower than that in the control group (p < 0.05). There was no significant difference in throat inflammation and dehydration between the two groups (p > 0.05). In addition, graded nutrition interventions significantly improved patients’ quality of life, including dimensions of physical functioning, role physics, physical pain, and social functioning. Conclusion Compared with conventional treatment, personalized graded nutrition intervention can significantly improve the swallowing function and reduce the pulmonary infection rate in patients with swallowing disorders after stroke.

A clinical study on gastric cancer patients administered EN and PN versus PN alone in enhanced recovery after surgery.

Enhanced recovery after surgery (ERAS) recommends avoiding enteral nutrition (EN) due to undesirable sequelae such as pulmonary aspiration and infections. Not using of EN in nongastric resections under ERAS pathways is often successful. However, parenteral nutrition (PN) alone followed by early postoperative oral feeding in gastric cancer patients, recommended by the ERAS guidelines, has unclear benefit and is only adopted after gastric resection. This study aimed to compute the postoperative outcomes of EN and PN compared to those of the ERAS-recommended nutritional pathway. Our secondary objective was to compare postoperative complications between the two groups. Of 173 gastrectomy patients, 116 patients were in the combined group (EN and PN), whereas 57 patients were in the PN alone group. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) version 26.0.0 software. The data were analyzed by one-way ANOVA, the independent sample t-test, or, in the case of several independent samples, by the Kruskal-Wallis test. Categorical data were analyzed by Pearson's χ2 test or Fisher's exact test. The observed indices included C-reactive protein (CRP), platelet (PLT), white blood cells (WBC), hemoglobin (Hb), albumin, and PRE-albumin. The secondary outcomes included length of hospital stay (LOS), cost, incidence of pulmonary infection, and total incidence of infection. The combined mode of nutrition is feasible and is not associated with postoperative complications in gastric cancer patients under ERAS.

Application of improved Beck oral score in oral care of burn patients with mechanical ventilation

Objective: To explore the application effect of improved Beck oral score in oral care of burn patients with mechanical ventilation, to provide practical basis for oral care of such patients.Methods: A total of 42 patients with tracheotomy and mechanical ventilation in the Department of Burn Surgery of Baogang Hospital in Inner Mongolia from January 2021 to December 2022 were selected as the study objects, and the patients were randomly divided into observation group and control group, with 21 cases in each group. The control group was given routine oral care, and the observation group was given oral care according to improved Beck oral score. The following were compared between the two groups: Age, total burn area, third-degree burn area, acute physiological and chronic health assessment scores, as well as improved Beck oral scores; the incidence of oral odor, plaque index, mouth ulcer and ventilator-associated pneumonia (VAP) after 7 days; the detection of microorganism in oral secretions.Results: After 7 days, the oral condition of patients in observation group was effectively improved, and the oral comfort level was significantly improved. The incidence of oral odor (2.57±1.59), dental plaque index (2.62±1.47), oral ulcer evaluation (2.24±1.09), VAP incidence (9.52%) and improved Beck oral score (8.09±1.92) in observation group were all lower than those in control group, which was (3.95±1.82), (3.57±1.21), (3.14±1.24), (38.09%), and (9.90±2.21) respectively. The difference was statistically significant (p &lt; .05). The oral normal flora in observation group (71.43%) was higher than that in control group (28.57%), and the difference was statistically significant (p &lt; .05). The oral gram-positive bacteria (19.05%) and Gram-negative bacteria (23.81%) in observation group were lower than those in control group, which was 52.38% and 57.14% respectively, and the difference was statistically significant (p &lt; .05).Conclusions: The application of the improved Beck oral assessment method in dynamic oral care can effectively reduce the content of oral pathogens, lower the incidence of pulmonary infection, and improve the quality of life of patients.

The significance of admission blood lactate and fibrinogen in pediatric traumatic brain injury: a single-center clinical study

BackgroundTraumatic brain injury (TBI) is a significant cause of morbidity and mortality in pediatric patients, leading to long-term physical, cognitive, and psychological impairments. Blood lactate and fibrinogen levels have emerged as potential biomarkers associated with tissue hypoperfusion and coagulation dysfunction, respectively. However, limited research has specifically focused on the significance of these biomarkers in pediatric TBI. This study aimed to investigate the clinical significance of blood lactate and fibrinogen levels upon admission in pediatric patients with traumatic brain injury.MethodsThe medical records of 80 children with a traumatic brain injury who were admitted from January 2017 to January 2021 were retrospectively analyzed. The two groups were compared according to whether the blood lactate in the admission arterial blood gas increased and the fibrinogen content in the coagulation function decreased. The clinical data of the children in the two groups were different, and then they were divided into a good prognosis group and a poor prognosis group according to the GOS prognostic score, and the differences in the clinical indicators of the two groups were compared.ResultsAmong the 80 patients, 33 had elevated blood lactate levels, 34 had decreased fibrinogen levels, and 29 had an unfavorable outcome (GOS < 4). Compared to the normal blood lactate group, there were no statistically significant differences in age, sex ratio, or platelet count in the elevated blood lactate group (P > 0.05). However, the elevated blood lactate group had lower Glasgow Coma Scale (GCS) scores upon admission, higher blood lactate levels, lower fibrinogen levels, longer hospital stay, lower GOS scores, and a higher proportion of GOS < 4 (P < 0.05). Compared to the normal fibrinogen group, there were no statistically significant differences in age, sex ratio, or platelet count in the decreased fibrinogen group (P > 0.05). However, the decreased fibrinogen group had lower GCS scores upon admission, higher blood lactate levels, lower fibrinogen levels, longer hospital stays, lower GOS scores, and a higher proportion of GOS < 4 (P < 0.05). Compared to the favorable outcome group, there were no statistically significant differences in age, sex ratio, or platelet count in the unfavorable outcome group (P > 0.05). However, the unfavorable outcome group had lower GCS scores upon admission, higher blood lactate levels, lower fibrinogen levels, longer hospital stays, a higher incidence of pulmonary infection, a higher incidence of stress ulcers, and lower GOS scores (P < 0.05).ConclusionThe levels of blood lactate and fibrinogen may represent the severity of children with traumatic brain injury and may be risk factors for poor prognosis of children with traumatic brain injury.

Plastic bronchitis associated with respiratory syncytial virus infection: a case report

BackgroundThe etiology of Plastic bronchitis (PB) is unknown. The incidence of pulmonary infection associated with PB has increased year by year, but respiratory syncytial virus (RSV) as a pathogen causes PB has rarely been reported.Case presentationA 2-year-old immunocompromised girl was admitted to the hospital with cough, fever for 5 days, and aggravated with shortness of breath for 1 day. With mechanical ventilation, her respiratory failure was not relieved, and subcutaneous emphysema and mediastinal pneumatosis appeared. Extracorporeal membrane oxygenation (ECMO) was administrated, but the tidal volume was low. Therefore, a bronchoscopy was performed, by which plastic secretions were found and removed. Pathology of the plastic secretions confirmed the diagnosis of type I PB. RSV was the only positive pathogen in the alveolar lavage fluid by the next-generation sequencing test. After the bronchoscopic procedure, her dyspnea improved. The patient was discharged with a high-flow nasal cannula, with a pulse oxygen saturation above 95%. Half a year after discharge, she developed sequelae of bronchitis obliterans.ConclusionRSV could be an etiology of PB, especially in an immunocompromised child. In a patient with pulmonary infection, if hypoxemia is presented and unresponded to mechanical ventilation, even ECMO, PB should be considered, and bronchoscopy should be performed as soon as possible to confirm the diagnosis and to treat.

HER2 Amplification in Non-Mutant RAS Status in Patients with Metastatic Colorectal Cancer and the 2-Year Survival Rate

Introduction: HER2 amplification is a therapeutic target in breast and stomach cancer, but the relationship between HER2 and response to treatment in metastatic colorectal cancer has not been fully determined. This study investigated the incidence of HER2 overexpression in non-mutant RAS patients with metastatic colorectal cancer to determine the two-year survival rate in patients referred to Imam Khomeini Hospital in Sari between 2014-2018. Material and Methods: This cohort study was conducted between 2014 and 2018 among patients with metastatic colorectal cancer who were identified as non-mutant (wild) NRAS, KRAS, and BRAF genes. Patients received cetuximab. The clinical course of the patients was evaluated simultaneously during this evaluation period, and the two-year survival rate of the patients and the response to cetuximab were evaluated. Data were entered into SPSS software version 24 and analyzed. Results: Twenty-five patients were examined, 60% were men. The most common symptom in patients was abdominal pain (32%). The majority (72%) of the study patients did not undergo surgery, 24% underwent hemicolectomy and 4% underwent total colectomy. The incidence of HER2 positive in women was higher than in men (10% vs. 6%) and in grade 1 patients was higher than grade 2 (8.3% vs. 1.1%). Forty-four percents of patients had positive two-year survival. Among patients with positive two-year survival, 9.1% were HER2 positive and 90.9% were HER2 negative. Conclusion: The results of the study showed that infectious causes (influenza) and underlying CLD including asthma were major causes of ARF in pregnant women. Thus, more careful attention is needed to control the underlying disease, and planning for easier access to the influenza vaccine can play an effective role in reducing the incidence of pulmonary infections.

148. COMPARISON OF EARLY POSTOPERATIVE OUTCOME BETWEEN OPEN AND MINIMALLY INVASIVE TRANSTHORACIC ESOPHAGECTOMY FOR ESOPHAGEAL CANCER: A RETROSPECTIVE STUDY

Abstract Background Esophagectomy is a highly invasive surgical procedure for esophageal cancer, with open thoracotomy associated with a significant risk of pulmonary complications. Minimally invasive techniques, such as minimally invasive esophagectomy (MIE), are expected to reduce these complications and enhance postoperative recovery. This study aimed to compare the early postoperative outcomes of patients who underwent open esophagectomy versus MIE. Methods We conducted a retrospective study using a single-center database from January 1, 2010, to February 28, 2023, including patients aged 18–90 years with a resectable lesion of the esophagus or esophagogastric junction who underwent either open transthoracic esophagectomy or MIE (thoracoscopic/robotic-assisted). Patient data, surgical procedures, interventions, and early outcomes (within 30 days of operation) were collected and analyzed. The study included a total of 76 patients, with 50 patients in open esophagectomy group and 26 patients in MIE group. The primary outcome was the incidence of pulmonary complications during the hospital stay, and logistic regression was used for data analysis. Results The overall incidence of pulmonary complications was 37 cases (74%) in the open esophagectomy group and 14 cases (53.8%) in the MIE group, with the incidence of pulmonary infection occurring in 19 cases (38%) and 8 cases (30.8%), respectively. Perioperative mortality was 1 cases (2%) in the open esophagectomy group and 0 cases (0%) in the MIE group. After adjusting for age, sex, BMI, smoking, COPD, and operative time, the open esophagectomy group had a 4.29 times higher risk of pulmonary complications than the MIE group (odds ratio 4.29, 95% confidence interval 1.30–14.16; p = 0.017). Conclusion Our study demonstrates that MIE is associated with a lower incidence of pulmonary complications, reduced blood loss, and shorter ICU stays compared to open esophagectomy. Rates of anastomosis leakage, vocal cord paralysis, and hospital stays were comparable. These findings support the feasibility and safety of MIE, potentially improving surgical outcomes and enhancing postoperative recovery for the treatment of esophageal cancer.

Risk Factors for Post-Operative Pulmonary Infection in Patients With Brain Tumors: A Systematic Review and Meta-Analysis.

Background: This study aims to analyze the risk factors for post-operative pulmonary infection in patients with brain tumors by meta-analysis to provide a reference for its prevention. Methods: PubMed, Embase, Web of Science, Cochrane Library, Ovid, and four Chinese databases (CNKI, SinoMed, VIP, and Wanfang databases) were searched for studies covering risk factors of pulmonary infection in patients with brain tumors, limited to the duration from the dates of inception of the respective databases to December 31, 2022. The Newcastle-Ottawa scale was used to assess the evidence. A meta-analysis of the factors affecting the incidence of pulmonary infection was performed using Revman 5.4 software. Results: Twelve studies were selected, covering 35,615 patients with brain tumors, among whom pulmonary infection occurred in 1,635 cases with an accumulated incidence of 4.6%, including 38 related risk factors. Meta-analysis results indicated: history of chronic pulmonary disease (odds ratio [OR], 5.74; 95% confidence interval [CI], 1.34-24.51; p = 0.02], diabetes mellitus (OR, 1.58; 95% CI, 1.29-1.95; p < 0.0001), history of cardiovascular disease (OR, 3.97; 95% CI, 2.18-7.24; p < 0.00001), age ≥60 years (OR, 1.55; 95% CI, 1.12-2.15; p = 0.009)], operation time ≥3 hours (OR, 1.03; 95% CI, 1.00-1.05; p = 0.03], Glasgow Coma Scale (GCS) score <13 (OR, 3.5; 95% CI, 1.90-6.46; p < 0.0001), and the American Society of Anesthesiologists classification (ASA) ≥3 (OR, 2.03; 95% CI, 1.68-2.46; p < 0.00001) as independent risk factors. Conclusions: History of chronic pulmonary disease, diabetes mellitus, history of cardiovascular disease, age ≥60 years, operation time ≥3 hours, GCS score <13, and the ASA grade ≥3 are independent risk factors for post-operative pulmonary infection in patients with brain tumors, which nursing staff should be aware of.

Incidence of nontuberculous mycobacteria infections among persons with cystic fibrosis in the United States (2010–2019)

BackgroundNontuberculous mycobacteria (NTM) are ubiquitous, environmental bacteria that can cause chronic lung disease. Persons with cystic fibrosis (pwCF) are at high risk for NTM. Approximately 1 in 5 pwCF in the United States (U.S.) is affected by pathogenic NTM species, and incidence rates of NTM have been increasing among pwCF as well as in the general population. Prevalence of NTM pulmonary infections (PI) varies widely across the United States because of geographic variation in environmental exposures. This study will present updated region-level incidence of NTM infections in the cystic fibrosis (CF) population in the U.S.MethodsWe used the Cystic Fibrosis Foundation Patient Registry (CFFPR) data for the period 2010 through 2019. Our study population comprised persons with CF ≥ 12 years of age who had been tested for NTM PI. We included only registry participants with NTM culture results. We defined incident cases as persons with one positive mycobacterial culture preceded by ≥ two negative mycobacterial cultures. We defined non-cases as persons with ≥ two negative mycobacterial cultures. We estimated average annual NTM PI incidence by region. Using quasi-Poisson models, we calculated annual percent change in incidence by region.ResultsWe identified 3,771 incident NTM infections. Of these cases, 1,816 (48.2%) were Mycobacterium avium complex (MAC) infections and 960 (25.5%) were Mycobacterium abscessus infections. The average annual incidence of NTM PI among pwCF in the U.S. was 58.0 cases per 1,000 persons. The Northeast had the highest incidence of MAC (33.5/1,000 persons tested) and the South had the highest incidence of M. abscessus (20.3/1,000 persons tested). From 2010 to 2019, the annual incidence of total NTM PI increased significantly by 3.5% per year in the U.S.ConclusionsNTM PI incidence is increasing among pwCF. Identifying high risk areas and increasing trends is important for allocating public health and clinical resources as well as evaluating interventions.

Assessment of disease severity and patient prognosis in anti-GABABR encephalitis with and without comorbid tumors.

This study aimed to analyze the severity of the condition and prognosis of patients with anti-gamma-aminobutyric-acid type B receptor (anti-GABABR) encephalitis with tumors. Patients with anti-GABABR encephalitis admitted to one of two hospitals from 2020 to 2022 were enrolled and divided into tumor and non-tumor groups. The clinical characteristics, condition severity, treatment options, and prognosis of the two groups of patients were compared and analyzed. Eighteen patients with anti-GABABR encephalitis were included, ten of whom had tumors. The comparison of clinical characteristics showed that rates of status epilepticus and coma were significantly higher in the group with tumors (P = 0.013 and P = 0.025, respectively); the incidences of pulmonary infection, respiratory failure, hyponatremia, and hypoproteinemia were also substantially more frequent in the tumor group (P = 0.054, P = 0.036, P = 0.015, and P = 0.025, respectively). The laboratory test result comparison showed that serum neuron-specific enolase (NSE) and carcinoembryonic antigen (CEA) were present only in the group with tumors (P = 0.036 and P = 0.092, respectively), but there was no significant difference in the occurrence of elevated CEA between the two groups. Conversely, the percentage of serum systemic autoimmune antibodies was higher in the group without tumors than in the group with tumors (P = 0.043). Patients with tumors tended to have poor outcomes (P = 0.152, OR: 7.000). Severe brain damage and complications occur in patients with anti-GABABR encephalitis and comorbid tumors. Early screening for serum NSE and CEA helps in the early diagnosis and treatment of tumors. The prognosis is much worse for anti-GABABR encephalitis with tumors.

Effect of different ventilation modalities on the early prognosis of patients with sleep apnea after acute ischemic stroke–––protocol for a prospective, open-label and randomised controlled trial

BackgroundSleep apnea is highly prevalent after acute ischemic stroke (AIS) and has increased stroke-related mortality and morbidity. The conventional sleep apnea treatment is continuous positive airway pressure (CPAP) ventilation. However, it is poorly tolerated by patients and is not used in all stroke patients. This protocol describes the impact of high-flow nasal cannula (HFNC) oxygen therapy compared to nasal continuous positive airway pressure (nCPAP) ventilation or usual care on the early prognosis of patients with sleep apnea after AIS.MethodsThis randomised controlled study will be conducted in the intensive care unit of the Department of Neurology at the Wuhan Union Hospital. According to the study plan, 150 patients with sleep apnea after AIS will be recruited. All patients are randomly allocated in a 1:1:1 ratio to one of three groups: the nasal catheter group (standard oxygen group), the HFNC group, and the nCPAP group. Patients receive different types of ventilation after admission to the group, and their tolerance while using the different ventilation is recorded. Patients will be followed up by telephone three months after discharge, and stroke recovery is recorded. The primary outcomes were 28-day mortality, the incidence of pulmonary infection and endotracheal intubation.DiscussionThis study analyses different ventilation modalities for early interventions in patients with sleep apnea after AIS. We will investigate whether nCPAP and HFNC reduce early mortality and endotracheal intubation rates and improve distant neurological recovery in patients.Trial registrationThis trial was registered at ClinicalTrials.gov (NCT05323266; 25 March 2022).

The Surgical Timing and Prognoses of Elderly Patients with Hip Fractures: A Retrospective Analysis.

Guidelines exist for the surgical treatment of hip fractures, but the association between the surgical timing and the incidence of postoperative complications and other important outcomes in elderly patients with hip fracture remains controversial. This study aims to explore the association between the surgical timing and the prognoses in elderly patients with hip fracture. A total of 701 elderly patients (age ≥ 65 years) with hip fractures who were treated in our hospital from June 2020 to June 2021 were selected. Patients who underwent surgery within 2 d of admission were assigned to the early surgery group, and those who underwent surgery after 2 d of admission were assigned to the delayed surgery group. The prognosis indices of the patients in the two groups were recorded and compared. The length of postoperative hospitalisation in the early surgery group was significantly lower than that in the delayed surgery group (P < 0.001). The European quality of life questionnaire (EQ-5D) utility in the delayed surgery group was significantly lower than that in the early surgery group at 30 days and 6 months after operation (P<0.05). Compared with the delayed surgery group, the incidence of pulmonary infection, urinary tract infection (UTI) and deep vein thrombosis (DVT) in the early surgery group were significantly lower. There were no significant differences between the two groups in terms of mortality and excellent rates of the HHS at six months after the operation. In addition, the early surgery group had a lower readmission rate than the delayed surgery group [34 (9.5%) vs 56 (16.3%), P = 0.008]. Earlier surgery can reduce the incidence of pulmonary infections, UTI, DVT and readmission rate among elderly patients with hip fractures, shorten postoperative hospitalisation.

Effect of Cough Machine Assistance and Care Bundle Combined Therapy on Burned Patients With Moderate To Severe Inhalation Injury.

To investigate the effectiveness of cough machine assistance combined with care bundle on mental resilience and self-efficacy on burned patients with moderate to severe inhalation injury. Totally 98 burned patients with moderate to severe inhalation injury from April 2021 to April 2022 were enrolled in this retrospective analysis. They were divided into the control group (n = 49, conventional therapy) and combined-therapy group (n = 49, cough machine assistance and care bundles). The mental resilience, posttraumatic growth, and self-efficacy were conducted. The arterial blood gas analysis indicators and incidence of pulmonary infection were also evaluated. The length of hospital stay in combined-therapy group was significantly less than that of control group. There was no difference of pulmonary infections between two groups before treatment. However, the incidence of pulmonary infection in the combined-therapy group was significantly lower. After the therapy, the combined-therapy group showed significantly higher partial pressure of oxygen, and lower levels of oxyhemoglobin saturation and partial pressure of carbon dioxide compared with the control group. The evaluation with the mental resilience, posttraumatic growth, and self-efficacy after the therapy, indicated that the patients in the combined-therapy group had significantly higher scores of optimism, strength, tenacity, relating to others, new possibilities, personal strength, appreciation of life and spiritual change, and self-efficacy. The combined therapy with cough machine assistance and care bundles can effectively improve the mental resilience and self-efficacy level of burned patients with moderate to severe inhalation injury, showing potential for possible clinical applications.

Clinical characteristics and short-term outcomes of Japanese encephalitis in pediatric and adult patients: a retrospective study in Northern China.

The study aimed to compare the clinical characteristics and short-term outcomes of pediatric and adult Japanese encephalitis (JE) patients in order to find out the differences. From August 2006 to October 2019, 107 patients (62 pediatric patients and 45 adult patients) with JE were enrolled. Clinical characteristics and short-term outcomes were analyzed. The short-term outcome of each patient was defined as a good outcome or poor outcome according to their Glasgow Coma Scale (GCS) scores (GCS > 8 vs. GCS ≤ 8) at discharge. As for acute complications, the incidence of pulmonary infection was higher in 25 adults (25/45, 55.6%) than in 19 children (19/62, 30.6%; P = 0.01). Upper gastrointestinal bleeding was more common in patients with pulmonary infection, with 10 of these patients experiencing the symptom (10/44, 22.7%) compared to only one patient without pulmonary infection (1/63, 1.6%; P = 0.001). The proportion of mechanical ventilation and admission to the intensive care unit (ICU) for supportive care was higher in patients with pulmonary infection than in patients without infection (P < 0.001, P = 0.008, respectively). The GCS scores at discharge in patients with pulmonary infection (7, 4-12.75) were lower than in patients without pulmonary infection (14, 10-14; P < 0.001). Although the GCS scores at the admission of children (9.5, 7-13) were similar to that of adults (7, 6-13), the GCS scores at the discharge of adults (7, 3.5-13) were lower than that of children (13, 10.75-14; P < 0.001). The short-term outcome of JE was worse in adults. Pulmonary infection was correlated with a high incidence of upper gastrointestinal bleeding, mechanical ventilation, and ICU hospitalization in JE. Pulmonary infection is a prognostic predictor of short-term outcomes in patients with JE. Vaccination for adults should be initiated.
