Primary spontaneous pneumothorax (PSP) occurs more frequently in young, tall men, with approximately 10,000 times video-assisted thoracoscopic surgery (VATS) annually in Japan is undergoing for surgical treatment. The underlying mechanisms remain unclear, but several reports have suggested correlation with weather conditions. This study aimed to evaluate the relationship between onset of PSP and changes in weather.
We retrospectively analyzed data from 112 patients who underwent VATS for PSP in Iwate, Japan from 1 January 2010 to 14 June 2020. Of the 3,818 days in this study period, the day on which the patient became aware of symptoms was classified as the PSP onset day (n=112), and all others were classified as PSP non-onset day (n=3,706). Meteorological data were collected from airbase station using an online source for the same place and same time. Logistic regression modeling was used to obtain predicted risks for the onset of PSP with respect to weather conditions.
Among the meteorological parameters, significant differences were mainly found at 2 days before onset for increasing average temperature [odds ratio (OR) 1.97, P=0.018], minimum temperature (OR 1.97, P=0.018), average humidity (OR 1.58, P=0.043), and decreased the sunshine time (OR 2.26, P=0.012). No significant difference was observed in atrophic pressure at 2 days before onset.
Onset of PSP may correlate with the increased temperature and humidity, seen with an approaching of warm front.

Virtually all patients with medically inoperable stage I non-small cell lung cancer (NSCLC) can receive stereotactic body radiation therapy. However, the percentage of such patients in whom sublobar resection is technically feasible is unknown. This discrepancy can confound clinical trial eligibility and designs comparing stereotactic body radiation therapy
. sublobar resection.
A total of 137 patients treated with stereotactic body radiation therapy for lung lesions (3/2013-11/2017) underwent retrospective review. Diagnostic CT chest and PET/CT images, stereotactic body radiation therapy dates, and demographic data were collected on 100 of 137 patients. Two experienced board-certified thoracic surgeons independently reviewed anonymized patients' pre-stereotactic body radiation therapy diagnostic imaging and completed a custom survey about the technical feasibility of sublobar resection for each patient. Temsirolimus clinical trial Interrater agreement was measured using Cohen's kappa coefficient by bootstrap methodology. Summary
Stereotactic body radiation therapy for stage I NSCLC is applicable to more tumors than sublobar resection, with ~30-35% of stereotactic body radiation therapy patients unable to undergo sublobar resection assessed by pretreatment diagnostic imaging based on technical grounds. This study illustrates that clinical trials comparing stereotactic body radiation therapy vs. sublobar resection are limited to only a subpopulation of patients with stage I NSCLC.
Critical illness is associated with cognitive, physical, and psychological impairments; however, evidence of the severity and frequency of impairments in Chinese survivors of mechanical ventilation in an intensive care unit (ICU) remains limited. Our aim was to investigate the incidence and severity of impairments in Chinese survivors of mechanical ventilation in ICU and to explore risk factors influencing specific impairments.
Patients discharged alive after mechanical ventilation in a large general ICU for ≥2 days were enrolled in this single-center cross-sectional study. Survivors were evaluated using measures of functional disability (Activity of Daily Living Scale), and post-traumatic stress disorder (PTSD, The Impact of Event Scale-Revised) via telephone interview. Multivariable analysis was conducted.
Data were obtained from 130 consenting survivors. At follow-up (mean 19.64 months), among those in part-time or full-time employment prior to admission, only 45.1% had returned to work. Further, 29.rs of mechanical ventilation in China face negative impacts on employment, and commonly have ADL impairment and PTSD. Age, ICU admission diagnosis, and APACHE II score were key factors influencing ADL, while ICU length of stay was the only factor affecting PTSD. These findings suggest that some survivors who have had certain exposures may warrant closer follow-up, and systematic interventions for these high-risk survivors should be developed in China.
Ventilatory inefficiency contributes to exercise intolerance in chronic obstructive pulmonary disease (COPD). The intercept of the minute ventilation (V
)
carbon dioxide output (V
CO
) plot is a key ventilatory inefficiency parameter. However, its relationships with lung hyperinflation (LH) and airflow limitation are not known. This study aimed to evaluate correlations between the V
/V
CO
intercept and LH and airflow limitation to determine its physiological interpretation as an index of functional impairment in COPD.
We conducted a retrospective analysis of data from 53 COPD patients and 14 healthy controls who performed incremental cardiopulmonary exercise tests (CPETs) and resting pulmonary function assessment. Ventilatory inefficiency was represented by parameters reflecting the V
/V
CO
nadir and slope (linear region) and the intercept of V

plot. Their correlations with measures of LH and airflow limitation were evaluated.
Compared to control, the slope (30.5829, P<0.001).
V

Lymphadenectomy is an essential but challenging part of the surgical treatment for esophageal cancer. However, the previously reported learning curve for robotic esophagectomy primarily focused on only one surgical approach (McKeown or Ivor Lewis). However, both approaches must be mastered by a mature robotic surgical team to deal with different clinical conditions and satisfy patients' needs. This study aimed to show how an experienced esophageal surgical team became proficient in both McKeown and Ivor Lewis robotic esophagectomy.
A retrospective review of the first 100 cases of robot-assisted minimally invasive esophagectomy (RAMIE) by a single surgical team was performed. The cumulative sum (CUSUM) analysis was used to distinguish the change point during the learning course. A subgroup analysis was performed according to a surgical approach (McKeown or Ivor Lewis) to determine the effect of experience from one surgical approach on learning the other RAMIE technique.
According to the tendency of the CUSUM plot, the learning curve was divided into four phases.
