BACKGROUND
In lung cancer, molecular testing and next-generation sequencing (NGS) are needed to identify therapeutic targets and are increasingly being used in earlier stages of the disease. Despite its longstanding use, it remains unclear whether transbronchial needle aspiration (TBNA) of peripheral lung lesions provides as adequate material for genetic testing as transbronchial forceps biopsies (TBFBs). In this study, we aim to analyze the use of TBNA using median viable cell area (MVCA) as a surrogate parameter to analyze sample quality.
METHODS
This prospective single-center study analyzed biopsy specimens or aspirates of patients who underwent bronchoscopy with transbronchial biopsy. Patients underwent bronchoscopy with TBFB and TBNA for suspected lung cancer in peripheral lung lesions. Patients were randomized 1:1 to receive either TBFB or TBNA as the first biopsy technique and then switched to the other. After routine workup, sample slides were digitally scanned, and MVCA was calculated by a pathologist blinded to the biopsy technique used. The primary endpoint was MVCA of TBNA versus TBFB. Secondary endpoints were complications categorized as bleeding, pneumothorax, and other.
RESULTS
Between August 2021 and April 2022, 15 patients were included in the per-protocol analysis. Six patients were included in cohort 1 and nine patients in cohort 2. A malignant diagnosis was confirmed in 11/15 (73.3%) cases, of which nine were primary lung malignancies. Overall, MVCA in samples obtained by TBFB was significantly larger than TBNA samples {TBFB-MVCA 9.80 mm [interquartile range (IQR), 2.70-10.39 mm] . TBNA-MVCA 2.70 mm (IQR, 0.14-8.21 mm), P=0.008}. Despite this difference, molecular testing was feasible in both TBNA and TBFB samples. No major complications were observed.
CONCLUSIONS
Despite a significantly smaller MVCA provided by TBNA, samples were still considered feasible for NGS, indicating that TBNA represents an alternative method to obtain sufficient tumor tissue in peripheral nodules as part of the diagnosis of suspected lung cancer.

OBJECTIVES
Characterize short-term outcomes of late preterm and term infants who received positive pressure ventilation in the delivery room and compare these with infants who did not receive resuscitation at birth.
STUDY DESIGN
Single center retrospective cohort study of infants born between 35 0/7 and 41 6/7 weeks' gestation in 2019. Baseline characteristics and outcomes of infants who received positive pressure ventilation were compared with controls who did not receive delivery room ventilation. The primary outcome was neonatal intensive care unit admission; secondary outcomes included multiple hospital morbidities and interventions.
RESULTS
Among 202 infants who received delivery room positive pressure ventilation, 77 (38.1%) received ≤1 min, and 125 (61.9%) received >1 min of positive pressure ventilation. Neonatal intensive care unit admission directly following resuscitation was more common in the ventilation cohort (33%) compared with controls (1.5%), ≤ 0.0001. After initial admission to the newborn nursery, intensive care unit transfer rates were similar in the positive pressure ventilation cohort (4%) and controls (5%). Antibiotic exposure, hypoxic ischemic encephalopathy, respiratory support in the neonatal intensive care unit, and pneumothorax were more common in the ventilation cohort. The composite outcome of any post-delivery complication occurred in 45% of positive pressure ventilation-exposed infants, compared to 15.8% of control infants (<0.0001); this was more common following >1 min (52.8%) than ≤1 min positive pressure ventilation (32.5%), = 0.002.
CONCLUSION
Post-delivery complications are common following delivery room positive pressure ventilation, emphasizing the need for post-resuscitation monitoring in either the neonatal intensive care unitor newborn nursery setting.

PURPOSE
The purpose of this study was to compare the effect of ultrasound-guided continuous erector spinae plane block to continuous thoracic paravertebral block on postoperative analgesia in elderly patients who underwent thoracoscopic lobectomy.
DESIGN
Randomized controlled trial.
METHODS
Elderly patients (N = 50) who underwent nonemergent thoracoscopic lobectomy in the thoracic surgery department of our hospital from January 2019 to December 2020 were selected and randomly divided into continuous erector spinae block (ESPB; n = 25) group and continuous thoracic paravertebral block (TPVB; n = 25) group. The patients in the two groups were guided by ultrasound with ESPB or TPVB before anesthesia induction. The visual analog scale at rest and cough in 2 hours, 6 hours, 8 hours, 12 hours, 24 hours, 48 hours after surgery, the supplementary analgesic dosage of tramadol, time of tube placement, the stay time in postanesthesia care unit (PACU), the first ambulation time after surgery, the length of postoperative hospital stay and postoperative complications were recorded.
FINDINGS
There were no significant differences between the two groups in visual analog scale score at rest and cough at each time point and supplementary analgesic dosage of tramadol within 48 hours after surgery (P > .05). The time of tube placement and the postoperative hospital stay in ESPB group was significantly shorter than that in TPVB group (P < .05). There were no differences in PACU residence time and first ambulation time between the two groups (P > .05). There were 4 patients in TPVB group and 2 patients in ESPB group who had nausea and vomiting (P > .05), 1 case of pneumothorax and 1 case of fever in the TPVB group. There were no incision infections or respiratory depression requiring clinical intervention in either group.
CONCLUSIONS
Both ESPB and TPVB alleviated the patients postoperative pain effectively for elderly patients underwent thoracoscopic lobectomy. Compared with TPVB, patients with ESPB have a shorter tube placement time, fewer complications and faster postoperative recovery.

Meta-Analysis Review
BACKGROUND
Pneumothorax is the most frequent complication after CT-guided percutaneous transthoracic lung biopsy (CT-PTLB). Many studies reported that injection of autologous blood patch (ABP) during biopsy needle withdrawal could reduce the pneumothorax and chest tube insertion rate after CT-PTLB, but the result is debatable. The aim of this systematic review and meta-analysis is to synthesize evidence regarding the efficacy of ABP procedure in patients receiving CT-PTLB.
METHODS
Eligible studies were searched in Pubmed, Embase and Web of Science databases. The inclusion criteria were studies that assessed the relationship between ABP and the pneumothorax and/or chest tube insertion rate after CT-PTLB. Subgroup analyses according to study type, emphysema status and ABP technique applied were also conducted. Odds ratio (OR) with 95% confidence interval (CI) were calculated to examine the risk association.
RESULTS
A total of 10 studies including 3874 patients were qualified for analysis. Our analysis suggested that ABP reduced the pneumothorax (incidence: 20.0% vs. 27.9%, OR = 0.67, 95% CI = 0.48-0.66, P < 0.001) and chest tube insertion rate (incidence: 4.0% vs. 8.0%, OR = 0.47, 95% CI = 0.34-0.65, P < 0.001) after CT-PTLB. Subgroup analysis according to study type (RCT or retrospective study), emphysema status (with or without emphysema), and ABP technique applied (clotted or non-clotted ABP) were also performed and we found ABP reduced the pneumothorax and chest tube insertion rate in all subgroups.
CONCLUSIONS
Our study indicated that the use of ABP was effective technique in reducing the pneumothorax and chest tube insertion rate after CT-PTLB.

BACKGROUND
While positive pressure ventilation has been considered an important contributing factor associated with pulmonary air leaks, studies examining the association between specific ventilatory settings during acute-phase high-frequency oscillatory ventilation (HFOV) and pulmonary air leaks among extremely preterm infants are limited.
METHODS
This was a single-center retrospective cohort study conducted at an institution that primarily used HFOV after intubation in extremely preterm infants. We analyzed data from extremely preterm infants born between 2010 and 2021. The primary outcome was pulmonary air leakage during the first 7 days of life. The exposure variable was the maximum mean airway pressure (MAP) on HFOV during the first 7 days of life or before the onset of pulmonary air leaks. Maximum MAP was categorized into three groups: low (7-10 cmHO), moderate (11-12 cmHO), and high (13-15 cmHO) MAP categories. We conducted robust Poisson regression analyses after adjustment for perinatal confounders, using the low MAP category as the reference.
RESULTS
The cohort included 171 infants (low MAP, 123; moderate MAP, 27; and high MAP, 21). The median (interquartile range) gestational age and birth weight were 25.7 (24.3-26.7), 25.7 (24.9-26.9), and 25.3 (24.3-26.6) weeks and 760 (612-878), 756 (648-962), and 734 (578-922) g for infants in the low, moderate, and high MAP categories, respectively. Compared to infants in the low MAP category, those in the high MAP category had a higher incidence of pulmonary air leaks (4.1% vs. 33.3%; adjusted risk ratio, 5.4; 95% confidence interval, 1.6-18.5). In contrast, there was no clear difference in the risk of pulmonary air leaks between the moderate and low MAP categories (3.7% vs. 4.1%; adjusted risk ratio, 0.9; 95% confidence interval, 0.1-6.1).
CONCLUSION
Extremely preterm infants requiring high MAP (≥13 cmHO) in acute-phase HFOV had a higher risk of pulmonary air leak during the first 7 days of life.

Journal of the Korean Society of... May 2024This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications.
PURPOSE
This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications.
MATERIALS AND METHODS
We conducted a retrospective review of 477 lung biopsy CT scans performed during free breathing. The respiratory phases during pleural puncture were determined based on the table position of the targeted nodule using CT scans obtained during free breathing. We compared the rates of complications among the inspiratory, mid-, and expiratory respiratory phases. Logistic regression analysis was performed to control confounding factors associated with pneumothorax.
RESULTS
Among the 477 procedures, pleural puncture was performed during the expiratory phase in 227 (47.6%), during the mid-phase in 108 (22.6%), and during the inspiratory phase in 142 (29.8%). The incidence of pneumothorax was significantly lower in the expiratory puncture group (40/227, 17.6%; = 0.035) and significantly higher in the mid-phase puncture group (31/108, 28.7%; = 0.048). After controlling for confounding factors, expiratory-phase puncture was found to be an independent protective factor against pneumothorax (odds ratio = 0.571; 95% confidence interval = 0.360-0.906; = 0.017).
CONCLUSION
Our findings suggest that pleural puncture during the expiratory phase may reduce the risk of pneumothorax during image guided PTNB.

Randomized Controlled Trial Comparative Study
Comparison of ultrasound-guided rhomboid intercostal and subserratus plane block versus thoracic paravertebral block for analgesia in thoracoscopic surgery: a randomized, controlled, non-inferiority trial.
BACKGROUND
To investigate the non-inferiority of ultrasound-guided rhomboid intercostal and subserratus plane (RISS) block compared to thoracic paravertebral block (TPVB) in postoperative analgesia for thoracoscopic surgeries.
METHODS
This study consecutively enrolled 50 patients undergoing elective thoracoscopic surgery. Following general anesthesia, the RISS group received a unilateral block with 40 mL of 0.25% ropivacaine, while the TPVB group received with 30 mL of 0.33% ropivacaine. The primary outcome measure was the 24-hour postoperative resting VAS score. Secondary outcome measures included nerve block operation time for two groups, postoperative 1, 2, 4, 8, 48-hour resting VAS scores, and different time points coughing VAS scores, time to first postoperative ambulation, total intravenous analgesic consumption at different time points postoperatively, complications related to the block.
RESULTS
There were no significant statistical differences between the two groups in terms of postoperative rest and cough VAS scores at each time (P>0.05), and the mean difference in rest VAS scores did not exceed the non-inferiority margin in 95% CI. There were no significant differences in total intraoperative and postoperative analgesic consumption at different time points (P>0.05), and no significant differences in time to first postoperative ambulation (P>0.05). Compared to the TPVB group, the RISS group had a shorter nerve block operation time (259.43±30.11 vs. 335.23±30.96 s, P<0.001) and fewer instances of intraoperative hypotension (two vs. seven cases, P=0.022), bleeding at the puncture site, pneumothorax, and arrhythmia.
CONCLUSIONS
In thoracoscopic surgeries, the postoperative analgesic efficacy of ultrasound-guided RISS block is not inferior to TPVB. Compared to TPVB, RISS block is simpler, quicker, and associated with fewer puncture-related complications.

Background The report of epidemiological data on coronavirus disease 2019 (COVID-19) patients treated using extracorporeal membrane oxygenation (ECMO) in Japan has been limited. Our study seeks to fill the existing gap in knowledge by providing an in-depth analysis of the clinical epidemiological characteristics and diverse medical outcomes of COVID-19 patients treated with ECMO in Japan. Methods This study used the COVID-19 Registry Japan nationwide database. We included patients aged 18 years or older enrolled between March 17, 2020, and February 1, 2022, with traceable ECMO data. The items on clinical epidemiological characteristics and various medical outcomes were collected. Statistical analysis included a median and interquartile range (IQR) for continuous variables and frequencies for categorical variables. Results The number of participating hospitals was 731, and the number of patients enrolled for analysis was 49,590. Of these, 196 (0.4%) patients received ECMO. Hospital mortality was 33.2%, and discharge to home was 23.0% in the ECMO group. The complications during hospitalization included pneumothorax (9.7%), seizures (4.1%), stroke (4.6%), and pulmonary thromboembolism (2.0%). At discharge, 38.3% had worsened self-care ability, and 38.8% had worsened ambulatory function. Conclusions The results of ECMO treatment in Japan showed that the mortality and complication rates were well-controlled compared with those worldwide.

We present an AIDS patient coinfected with nontuberculous mycobacteria, and COVID-19, who finally recovered from the coinfection. The 36-year-old man had two hospitalizations. In the first hospitalization, the patient was diagnosed with , HIV, and COVID-19 quickly and accurately, and the corresponding treatment worked well. The second hospitalization can be divided into four stages: (1) Persistent fever period; (2) Persistent fever and Pulmonary Progression; (3) ICU period; and (4) Pneumothorax period. During the second hospitalization, the diagnosis of Mycobacterium colombiense was hard because the NGS, acid-fast bacilli, and culture of vomit, sputum, and bronchoalveolar lavage fluid were all negative. Still, we detected acid-fast bacilli in the blood mycobacterium culture. In conclusion, we report a severe pneumonia AIDS patient coinfected with , COVID-19, and Mycobacterium colombiense who finally recovered from the disease. Nontuberculous mycobacteria infection is common in HIV patients, but bronchoalveolar lavage fluid NGS cannot identify nontuberculous mycobacteria in our report. Traditional blood culture was useful in detecting acid-fast bacilli in our study and then detecting the pathogens with NGS. Combining traditional microbial culture and emerging rapid NGS methods is more conducive to clinical diagnosis and treatment.

Observational Study
Evaluating the Shock Index, Revised Assessment of Bleeding and Transfusion (RABT), Assessment of Blood Consumption (ABC) and novel PTTrauma score to predict critical transfusion threshold (CAT) in penetrating thoracic trauma.
The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64-14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826-0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.
