Abstract
Ramucirumab plus docetaxel (RD) can cause febrile neutropenia (FN), which frequently requires the prophylactic administration of pegfilgrastim. However, the effects of prophylactic pegfilgrastim on FN prevention, therapeutic efficacy, and prognosis after RD have not been fully evaluated in patients with advanced non-small-cell lung cancer (NSCLC). Two hundred and eighty-eight patients with advanced NSCLC who received RD as second-line therapy after platinum-based chemotherapy plus PD-1 blockade were included. Patients were divided into groups with and without prophylactic pegfilgrastim, and adverse events, efficacy, and prognosis were compared between both groups. Of the 288 patients, 247 received prophylactic pegfilgrastim and 41 did not. The frequency of grade 3/4 neutropenia was 62 patients (25.1%) in the pegfilgrastim group and 28 (68.3%) in the control group (p < 0.001). The frequency of FN was 25 patients (10.1%) in the pegfilgrastim group and 10 (24.4%) in the control group (p = 0.018). The objective response rate was 31.2% and 14.6% in the pegfilgrastim and control groups (p = 0.039), respectively. The disease control rate was 72.9% in the pegfilgrastim group and 51.2% in the control group (p = 0.009). Median progression free survival was 4.3 months in the pegfilgrastim group and 2.5 months in the control group (p = 0.002). The median overall survival was 12.8 and 8.1 months in the pegfilgrastim and control groups (p = 0.004), respectively. Prophylactic pegfilgrastim for RD reduced the frequency of grade 3/4 neutropenia and febrile neutropenia and did not appear to be detrimental to patient outcome RD.Clinical Trial Registration Number: UMIN000042333.

Abstract
BACKGROUND Evidence for use of second-line immunosuppressants for immune-related adverse events (irAEs) is inadequate. Therefore, a multicenter analysis should assess the efficacy of second-line immunosuppressants for severe irAEs associated with different malignant diseases. METHODS This descriptive study aims to investigate the effects of second-line immunosuppressants on corticosteroid-refractory irAEs in patients with lung cancer. We analyzed the effects of second-line immunosuppressants on underlying lung cancer and associated adverse effects. RESULTS Our study included 4589 patients who had received immune checkpoint inhibitor treatment, with 73 patients (1.6%) developing irAEs requiring second-line immunosuppressants. The most commonly observed irAE was pneumonitis (26 patients), followed by hepatobiliary disorders (15 patients) and enteritis (14 patients). We found a confirmed response rate of 42.3% for pneumonitis, which was lower than the response rates of 86.7% for hepatobiliary disorders and 92.9% for enteritis. The time from the start of corticosteroid therapy to the addition of a second-line immunosuppressant correlated significantly with the resolution of irAE to Grade 1 (correlation coefficients of r = 0.701, p < 0.005). The median progression-free survival and duration of response of underlying lung cancer from second-line immunosuppressant administration were 2.1 and 3.0 months, respectively. Of the patients with irAE, 27.4% developed infections and 5.5% might die due to infection. CONCLUSION Second-line immunosuppressant response was confirmed in 72.2% of irAEs in patients with lung cancer, with lower response rates observed in irAE pneumonitis compared to other irAEs.

Abstract
BACKGROUND Para-tracheal or para-carinal air cysts (PACs) are often asymptomatic and usually detected incidentally by methods such as computed tomography. Their clinical significance is unclear in patients with pleuroparenchymal fibroelastosis (PPFE). METHODS We evaluated the clinical significance of PACs in PPFE and their relationship with pneumomediastinum or pneumothorax. RESULTS In total, 50 patients had PPFE and 34 (68%) had PACs. Most PACs were para-carinal (n = 30). A para-tracheal air cyst was detected in only nine patients, which included five patients having both para-carinal and para-tracheal air cysts. Overall median survival was 24.7 months. Survival was not significantly different between the patients with [PACs(+)] and without PACs (P = 0.268). A high frequency (64%) of the complication of pneumomediastinum or pneumothorax occurred in the overall population during follow-up. Pneumomediastinum/pneumothorax occurred significantly more frequently in patients with PACs(+) than in those without (76.5% vs. 37.5%; P = 0.012). PACs(+) was the only significant risk factor for pneumomediastinum/pneumothorax. CONCLUSIONS Our data showed that PACs commonly occur in patients with PPFE, and most PACs were para-carinal air cysts. Additionally, PACs(+) was a significant risk factor for pneumomediastinum/pneumothorax; therefore, clinicians should be more aware of these complications during follow-up examination, particular in PACs(+) patients with PPFE.

Abstract
BACKGROUND Some patients with connective tissue disease (CTD)-associated interstitial lung disease (ILD) progress to pulmonary fibrosis over their disease course despite initial improvement, potentially indicating a poor prognosis. Transbronchial lung cryobiopsy (TBLC) is a new bioptic approach used in diffuse parenchymal lung diseases. This study of CTD-ILD assessed the utility of TBLC in determining therapeutic decision-making strategies. METHODS We analyzed medical records of 31 consecutive CTD-ILD patients who underwent TBLC focusing on radio-pathological correlation and disease course. A TBLC-based usual interstitial pneumonia (UIP) score was used that assessed three morphologic descriptors: i) patchy fibrosis, ii) fibroblastic foci, and iii) honeycombing. RESULTS Among the patients with CTD-ILD, 3 had rheumatoid arthritis, 2 systemic sclerosis, 5 polymyositis/dermatomyositis, 8 anti-synthetase syndrome, 6 Sjögren's syndrome, and 5 had microscopic polyangiitis. Pulmonary function test results showed a mean %FVC of 82.4% and %DLCO of 67.7%. Among the 10 CTD patients and TBLC-proven pathological UIP, 3 patients had prominent inflammatory cells in addition to a framework of UIP, and pulmonary function of most patients improved with anti-inflammatory agents. Six (40%) of 15 patients with TBLC-based UIP score ≥ 1 had a progressive disease course during follow-up, of whom 4 patients received anti-fibrotic agents. CONCLUSIONS TBLC in patients with CTD-ILD can help determine an appropriate medication strategy, particularly when UIP-like lesions are present. TBLC may be useful when judging which agents to prioritize, anti-inflammatory or anti-fibrotic, is difficult. Moreover, additional information from TBLC may be beneficial when considering early intervention with anti-fibrotic agents in clinical practice.

Abstract
BACKGROUND Ramucirumab plus docetaxel (RD) is a promising treatment for previously treated advanced non-small cell lung cancer (NSCLC). However, its clinical significance after platinum-based chemotherapy plus programmed death-1 (PD-1) blockade remains unclear. RESEARCH QUESTION What is the clinical significance of RD as a second-line treatment after the failure of chemo-immunotherapy in NSCLC? STUDY DESIGN AND METHODS In this multicentre retrospective study, 288 patients with advanced NSCLC who received RDas second-line therapy after platinum-based chemotherapy plus PD-1 blockade, at 62 Japanese institutions from January 2017 to August 2020, were included. Prognostic analyses were performed using the log-rank test. Prognostic factor analyses were performed using a Cox regression analysis. RESULTS A total of 288 patients were enrolled: 222 were men (77.1%), 262 were aged <75 years (91.0%), 237 (82.3%) had smoking history and 269 (93.4%) had a performance status (PS) of 0-1. One hundred ninety-nine patients (69.1%) were classified as adenocarcinoma (AC) and 89 (30.9%) as non-AC. The types of PD-1 blockade used in the first-line treatment were anti-PD-1 antibody and anti-programmed death-ligand 1 antibody in 236 (81.9%) and 52 (18.1%) patients, respectively. The objective response rate for RD was 28.8% (95% confidence interval [CI], 23.7-34.4). The disease control rate was 69.8% (95% CI, 64.1-75.0).The median progression free survival and overall survival were 4.1 months (95% CI, 3.5-4.6) and 11.6 months (95% CI, 9.9-13.9), respectively. In a multivariate analysis, non-AC and PS 2-3 were independent prognostic factors for worse progression free survival , while bone metastasis on diagnosis, PS 2-3 and non-AC were identified as independent prognostic factors for poor overall survival. INTERPRETATION RD is a feasible second-line treatment in patients with advanced NSCLC who had received combined chemo-immunotherapy with PD-1 blockade.

Abstract
Background The difference in diagnostic yield between surgical lung biopsy and transbronchial lung cryobiopsy (TBLC) in diffuse parenchymal lung diseases (DPLD) has been reported to be due to differences in the rate of interpathologist agreement, specimen size, and specimen adequacy. In TBLC, the specimens containing large airway components are generally believed as inadequate specimens for histological evaluation, but the detailed characteristics of TBLC specimens including the large airway and the impact on histological diagnostic rates of DPLD have not been investigated. Methods We retrospectively reviewed the specimen characteristics of patients with DPLD who underwent TBLC. Results Between February 2018 and January 2020, 74 patients and 177 specimens were included. There were 85 (48.0%) large airway specimens (LAS) that contained bronchial gland or bronchial cartilage. The ideal specimen ratio was significantly lower in the LAS-positive group than that in the LAS-negative group (5.8% vs. 45.6%), and the proportion of bronchioles, alveoli, and perilobular area were similarly lower in the LAS-positive group. The presence of traction bronchiectasis and diaphragm overlap sign on high-resolution computed tomography (HRCT) were also significantly higher in the LAS-positive group than those in the LAS-negative group. We observed a statistically significant trend in histological diagnostic yield (40.7% in LAS positive group; 60.8% in LAS positive and negative group; 91.6% in LAS negative group) (Cochran-Armitage trend test). Conclusion LAS is a specimen often collected in TBLC and contains a low percentage of bronchioles, alveoli, and perilobular area. Since the histological diagnostic yield tends to be higher in cases that do not contain LAS, it may be important to determine the biopsy site that reduces the frequency of LAS collection by referring to the HRCT findings in TBLC.

Abstract
Several previous reports have shown interstitial lung disease (ILD) to be a predictor of poor prognosis in patients with chronic pulmonary aspergillosis (CPA). However, there is a lack of clarity regarding patient background and the prognostic factors in CPA associated with ILD (CPA-ILD). Therefore, we assessed these points to obtain valuable information for clinical practice. We retrospectively surveyed and collected data from 459 patients who had serum examination for anti-Aspergillus antibody. Of these patients, we extracted and investigated CPA-ILD patients. We ultimately analyzed 32 CPA-ILD patients. Patient background factors more frequently showed the patients to be older (mean: 74.9 years), male (75.0%), and to have a smoking history (71.9%). Median survival time from the diagnosis of ILD was 76.0 months, whereas that from the diagnosis of CPA-ILD was 25.5 months. No significant differences in survival were found in regard to each ILD pattern and the presence of idiopathic pulmonary fibrosis. A higher level of C-reactive protein was a significant predictor of mortality by Cox regression analysis. CPA complicating ILD is associated with poor prognosis. ILD patients with older age, male sex, and smoking history should be aware of the potential for the development of CPA in ILD. If such patients have elevated markers of inflammation, prompt induction of antifungal treatment may improve their prognosis. Clinicians should be aware of which complications of CPA may lead to a poor prognosis for any ILD not just those limited to idiopathic pulmonary fibrosis or usual interstitial pneumonia pattern.

Abstract
AIM This study aimed to assess the utility of ultrasound screening for pregnancies with positive noninvasive prenatal testing results for trisomy 21, trisomy 18, and trisomy 13. METHODS We performed a retrospective analysis of positive noninvasive prenatal testing results and first-trimester ultrasound screening at our department between 2013 and 2019. Invasive genetic testing was performed if the patient had positive noninvasive prenatal testing results. Fetal ultrasound and cytogenetic data were collected. Noninvasive prenatal testing was performed in the women for advanced maternal age, nuchal translucency thickness, or history of abnormality in the previous child or relative. RESULTS Forty-one pregnant women had positive noninvasive prenatal testing results for trisomy 21, trisomy 18, and trisomy 13. Twenty-three women had positive results for trisomy 21, 13 had positive results for trisomy 18, and 5 had positive results for trisomy 13 at 11 to 14 weeks of gestation. The positive predictive value of noninvasive prenatal testing was 100% for trisomy 21, 84.6% for trisomy 18, and 100% for trisomy 13. The positive predictive value of positive noninvasive prenatal testing results and fetal morphological abnormalities was 100% for trisomy 21, trisomy 18, and trisomy 13. CONCLUSION Combining an ultrasound examination with noninvasive prenatal testing resulted in a higher positive predictive value for trisomy 18. Normal ultrasound examination results can help alleviate stress caused by false-positive noninvasive prenatal testing results. In contrast, the positive predictive value and negative predictive value for trisomy 21 were not altered by adding an ultrasound examination to noninvasive prenatal testing.

Abstract
A 72-year-old Japanese man was admitted to our hospital for treatment of severe COVID-19 pneumonia and was started on favipiravir, heparin calcium, and methylprednisolone pulse therapy. He recovered from respiratory failure about one month later. However, he soon developed purpura in his lower limbs and thrombocytopenia, and immune thrombocytopenia was subsequently diagnosed. Although immune thrombocytopenia is one of the early complications of COVID-19, the use of corticosteroids for COVID-19 is thought to be a factor in the late onset of immune thrombocytopenia. In cases of severe COVID-19 for which corticosteroids were used for treatment, autoimmune diseases such as immune thrombocytopenia may manifest themselves late in the disease course.

Abstract
Background Myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) is often positive in patients with interstitial lung disease (ILD), which is also often present in patients with microscopic polyangiitis (MPA). A possible association between MPO-ANCA, MPA, and idiopathic ILD remains unclear. The objective of this study was to determine whether high-resolution computed tomography (HRCT) classification based on recent idiopathic pulmonary fibrosis guideline and specific CT findings can obtain new knowledge of prognostic factors in all MPO-ANCA-positive patients with ILD including both idiopathic ILD and MPA-ILD. Methods We analyzed 101 consecutive MPO-ANCA-positive patients with respiratory disease. We assessed the diagnostic accuracy of CT findings, HRCT pattern, and specific radiological signs. Prognostic predictors were determined using Cox regression models. Results Subjects with chronic ILD included 22 patients with MPA-ILD and 39 patients with ILD but without MPA. A quarter of the patients were radiological indeterminate for usual interstitial pneumonia (UIP) pattern, which resulted in a better prognosis than that for UIP pattern. “Increased attenuation around honeycomb and traction bronchiectasis” and “anterior upper lobe honeycomb-like lesion” were found to be highly frequent radiological findings (39% and 30%, respectively). In addition, the latter finding was a significant negative prognostic factor. Conclusions Radiological indeterminate for UIP was a useful HRCT classification in MPO-ANCA-positive patients with ILD. In addition, anterior upper lobe honeycomb-like lesion was found to be specific radiological finding that was a significant prognostic factor. The present results might aid in the assessment of appropriate strategies of diagnosis in these patients.

Abstract
Tracheobronchial lesions are rare extramuscular complications for idiopathic inflammatory myopathies including dermatomyositis. We herein report a 65-year-old woman with tracheal ulcer during the progression of dermatomyositis-associated interstitial lung disease. Treatment with corticosteroids combined with immunosuppressive agents resulted in improvement of the tracheal ulcer and pulmonary involvement. We believe that the tracheal ulceration might reflect the disease behaviour of dermatomyositis and dermatomyositis-associated interstitial pneumonia.

Abstract
OBJECTIVE To explore/study/evaluate the relationships among umbilical twist direction, the degree of umbilical twist and differences of umbilical arterial diameters (UAD). METHODS All obstetric patients presenting for prenatal care of singleton fetuses between 18 and 25 weeks gestation to a single provider (MN) from 2015 to 2018 had detailed umbilical cord Doppler measurements. Data including the cord twist direction, degree of twist and number of twists per cord segment length, and the diameters of each UA (UAD) and the umbilical vein (UVD) were extracted from the records. UAs were described as right or left depending on their position at the fetal cord insertion. Three groups were identified: Group A: right UAD > left UAD and Group B: left UAD > right UAD Group C: equal UAD. The coiling index was calculated as the inverse of the length of cord required for one complete 360 degrees wrap of the UA around the cord. According to the difference of UADs, the variables of right and left UADs, the coiling index, and frequencies of umbilical twist direction were analyzed using non-parametric methods. RESULTS 485 singleton fetuses and umbilical cords were examined. The value of the antenatal coiling index in cases with left UAD greater than right was 0.43 ± 0.16, which was significantly higher than 0.38 ± 0.16 with right UAD greater than left (p = .001). There were significant differences between the two groups in the values of right and left UAD, value of right minus left UAD, absolute value between right and left UAD, antenatal coiling index, antenatal coiling index due to umbilical twist direction and frequencies of cord twist direction. CONCLUSION The direction of umbilical twist may be in part dependent on differences in diameters of the umbilical arteries, in addition to other fetal characteristics such as fetal movement, or handedness of fetus or mother, fetal hemodynamic forces and structure of muscles of umbilical vessels.

Abstract
A 60-year-old Japanese woman was admitted to our hospital with a fever and shortness of breath occurring immediately after using hairspray. Chest high-resolution computed tomography (HRCT) showed ground-glass opacities (GGOs) predominantly distributed around the bronchovascular bundles, and a pathological evaluation by a transbronchial lung cryobiopsy (TBLC) revealed fibrotic non-specific interstitial pneumonia (f-NSIP). Her symptoms disappeared without the use of corticosteroids, and GGOs on HRCT improved markedly over time. This case suggests that a pathological evaluation by a TBLC for lung injury due to inhalation pathogen exposure may provide a more accurate diagnosis and a better understanding of the pathology from bronchial to interstitial lesions than transbronchial lung biopsy.

Abstract
We herein report four cases of diffuse bronchiolitis proven by a transbronchial lung cryobiopsy (TBLC). Based on various aspects, including the pathological findings, we definitively diagnosed two patients with diffuse panbronchiolitis (DPB) and the other two with primary ciliary dyskinesia (PCD). One of the DPB patients had more severe peribronchiolar fibrosis than the other, and the disease course was refractory to macrolide therapy. One of the PCD patients was additionally diagnosed with combined constrictive bronchiolitis. This report highlights the importance of a TBLC in the differentiation of bronchiolitis, suggesting its utility for helping pulmonologists formulate a treatment strategy.

Abstract
OBJECTIVE To verify the blood loss control effect of routine prophylactic Bakri balloon tamponade on major and minor placenta previa (PP). METHODS We conducted a retrospective cohort study of all singleton pregnancies that involved cesarean section (CS) for PP at our hospital. All participants were divided into Bakri balloon (underwent routine prophylactic use just after placenta removal) and non-balloon groups, and into major and minor PP groups. Clinical outcomes in major and minor PP were compared between balloon and non-balloon groups. RESULTS The balloon and non-balloon groups contained 74 and 89 patients, respectively. There were 41 and 33 (balloon group) and 48 and 41 (non-balloon group) major and minor PP cases, respectively. Intraoperative and perioperative blood losses of major PP were significantly lower in the balloon group than the non-balloon group (1045 ml versus 1553 ml, P = 0.016; and 1189 ml versus 1810 ml, P = 0.006, respectively). The frequency of massive postpartum hemorrhage (>500 ml) with major PP was lower in the balloon group than in the non-balloon group (2.4% versus 16.7%, P = 0.027), but with no significant difference with minor PP. CONCLUSION Routine prophylactic use of Bakri balloon tamponade during and after CS is effective in controlling blood loss in major PP.

BACKGROUND Secondary spontaneous pneumothorax (SSP) in interstitial lung disease (ILD) may influence prognosis of any ILD, and SSP onset predicts poor outcome in idiopathic pulmonary fibrosis (IPF). Recently, progressive fibrosing ILD (PF-ILD) has rapidly acquired importance. OBJECTIVE We hypothesized that PF-ILD would strongly influence the prognosis of patients with any ILD complicated with SSP. METHODS We retrospectively surveyed and collected data from patients hospitalized for SSP from January 2016 to June 2020. PF-ILD was defined as the following occurring within 24 months before SSP develops: relative decline in %forced vital capacity (FVC) ≥10% or two of the following: relative decline in %FVC between 5% and 10%, worsening respiratory symptoms, or increased extent of fibrosis on high-resolution computed tomography. RESULTS We analyzed 32 patients hospitalized for SSP in ILD. This study comprised 18 patients with PF-ILD and 14 patients with non-PF-ILD. PF-ILD patients had lower body mass index (BMI) and %FVC. No significant differences in survival regarding follow-up period from the time of ILD diagnosis and hospitalization for SSP were observed between the PF-ILD and non-PF-ILD patients. Older age and lower BMI were significant predictors of mortality by multivariate Cox regression analysis. ROC analysis showed BMI ≤17.8 kg/m2 to reliably predict poor prognosis. CONCLUSIONS Regardless of whether patients have PF-ILD, older age and lower BMI in patients with ILD places them at higher risk of developing SSP, and prognosis is poor if SSP develops. Therefore, clinical management of physique is important to improve the prognosis of ILD patients.

Abstract
An 85-year-old woman with antibiotics-resistant pneumonia after surgery for metastatic brain tumor from lung cancer was consulted to our department. Chest CT showed diffuse GGO bilaterally. BALF showed elevated ratios of lymphocytes and CD4/CD8. Tests for bacteria, mycobacteria, and fungi were negative. She improved following levetiracetam discontinuance and systemic corticosteroid administration, and we diagnosed levetiracetam-induced lung injury. Although levetiracetam is widely used, few reports of levetiracetam-induced pneumonia exist. Changes in chest images may occur after levetiracetam administration if patients have multiple risk factors for development of drug-induced interstitial lung disease. Bronchoscopy is useful for differential diagnosis if new lung lesions appear after starting levetiracetam.

Abstract
OBJECTIVES To evaluate the perinatal outcomes of hypocoiled cord. METHODS This retrospective study was carried out in the Department of Obstetrics and Gynecology at Showa University Hospital between 2011 and 2017. Umbilical cord index (UCI) was calculated by dividing the total number of coils by the total length of umbilical cord. All umbilical cords were measured and calculated coiling index by obstetrician after delivery. Perinatal outcomes like non-reassuring fetal status (NRFS), emergency cesarean sections, and other perinatal complications were compared. RESULTS From January 2011 to December 2017, a total of 4047 fetuses were born at our hospital after 28 weeks' gestation. After excluding 100 fetuses of hypercoiled cord, a total of 3947 fetuses were included in this study, of which 71 fetuses were hypocoiled cord and 3876 fetuses were normal coiled cord. There were no association between maternal background and both UCI group. NRFS during labor was significantly associated with hypocoiled cord compared with normal cord (p = .02). Additionally, the rates of emergency cesarean section were raised in cases of hypocoiled cord (p = .02). CONCLUSION In this study, it was found that hypocoiled cord is related to NRFS and emergency cesarean section. In addition, hypocoiled cord was not associated with any maternal factors. However, in previous studies, no opinion has been reported on the timing of diagnosis of hypocoiled cord during pregnancy. It is difficult to evaluate hypocoiled cord correctly in third trimester. It is a task to find the hypocoiled cord correctly before birth.

Abstract
BACKGROUND Interstitial lung disease (ILD) is associated with high morbidity and mortality in patients with connective tissue disease (CTD). Because some patients with CTD overlap present with ILD first, with CTD diagnosed later, specific radiologic signs are needed to help differentiate each CTD or CTD-ILD from idiopathic ILD. OBJECTIVES To determine whether specific CT findings can help differentiate CTD as rheumatoid arthritis (RA), systemic sclerosis (SSc), or polymyositis/dermatomyositis (PM/DM). METHODS We analyzed 143 consecutive ILD patients with RA, SSc, or PM/DM. We assessed diagnostic accuracy of CT findings of CTD-ILD, CT pattern, and signs including "anterior upper lobe honeycomb-like lesion" and "low attenuation area (LAA) within an interstitial abnormality" for each CTD-ILD. Prognostic predictors were determined using Cox regression models. RESULTS Subjects were 78 patients with RA-ILD, 38 with SSc-ILD, 24 with PM/DM-ILD, and 3 with overlapping CTD-ILD. High frequency of anterior upper lobe honeycomb-like lesion suggests that CTD-ILD is due to RA-ILD (22%) rather than SSc-ILD (8%) or PM/DM-ILD (8%), whereas LAA within an interstitial abnormality suggests that CTD-ILD is due to SSc-ILD (26%) rather than RA-ILD (4%) or PM/DM-ILD (0%). Multivariate analysis showed that while not associated with survival, current or ex-smoker, honeycombing, and acute exacerbation were negative prognostic factors of mortality. CONCLUSIONS The tendency is high for RA-ILD, in which anterior upper lobe honeycomb-like lesion is a specific feature, to show UIP or NSIP/UIP pattern, combined emphysema, and honeycombing; SSc-ILD to show NSIP pattern and LAA within an interstitial abnormality; and PM/DM-ILD to show NSIP pattern and non-honeycombing.

Abstract
Background Pulmonary alveolar proteinosis (PAP) is characterized by the accumulation of surfactant proteins within the alveolar spaces. Autoimmune PAP (APAP) caused by elevated levels of GM-CSF autoantibodies (GM-Ab) is very rarely associated with systemic autoimmune disease. Here we report a case of APAP manifested during immunosuppressive treatment for polymyositis with interstitial lung disease. Case presentation A 52-year-old woman treated at our hospital because of polymyositis with interstitial pneumonia had maintained remission by immunosuppressive treatment for 15 years. She had progressive dyspnea subsequently over several months with her chest CT showing ground-glass opacities (GGO) in bilateral geographic distribution. Her bronchoalveolar lavage fluid with cloudy appearance revealed medium-sized foamy macrophages and PAS-positive amorphous eosinophilic materials by cytological examination. We diagnosed her as APAP due to an increased serum GM-CSF autoantibody level. Attenuating immunosuppression failed to lead GGO improvement, but whole lung lavage (WLL) was effective in her condition. Conclusions PAP should be considered as one of the differential diseases when the newly interstitial shadow was observed during immunosuppressive treatment. WLL should be regarded as the treatment option for APAP concurred in connective tissue disease (CTD).

Abstract
OBJECTIVE We examined whether maternal serum cytokine profiles of mothers with early-onset fetal growth restriction (FGR) were associated with delivery within 2 weeks after sampling during the third trimester. STUDY DESIGN This exploratory prospective cross-sectional study included a total of 20 singleton fetuses with early-onset FGR and 31 healthy controls. Maternal serum samples during the early third trimester were analyzed for 23 cytokines. RESULTS Of 20 fetuses with early-onset FGR, 14 had delivery within 2 weeks after sampling. Multivariate analysis revealed that maternal serum concentrations of soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) and soluble CD40 ligand (sCD40L) were independently associated with delivery within 2 weeks in early-onset FGR. Among cases of early-onset FGR, concentrations of almost all maternal serum cytokines were similar. Maternal serum sVEGFR-1 concentrations were high when delivery occurred within 2 weeks. Maternal serum sCD40L concentrations were elicited only in cases in which delivery within 2 weeks occurred due to fetal deterioration. CONCLUSION We identified two biomarkers, one specific for FGR and the other dependent on severity, that were significant components of angiogenic activities and inflammation factors. Imbalances in serum protein expression may have a substantial effect on the pathogenesis of FGR.

Abstract
BACKGROUND Interstitial lung disease (ILD) is the most common and important pulmonary manifestation of rheumatoid arthritis (RA). A radiological honeycomb pattern has been described in diverse forms of ILD that can impact survival. However, the clinical course and sequential radiological changes in the formation of the honeycomb pattern in patients with RA-ILD is not fully understood. METHODS We evaluated the sequential changes in computed tomography findings in 40 patients with chronic forms of RA-ILD without the honeycomb pattern at initial diagnosis. We classified the patients into the Non-honeycomb group and Honeycomb group, and then analyzed the characteristics and prognosis of the two groups. The term "honeycomb formation" indicated a positive finding of honeycombing on any available follow-up CT. RESULTS Our RA-ILD cohort included patients with probable usual interstitial pneumonia (UIP) (35%), nonspecific interstitial pneumonia (NSIP) (20%), and mixed NSIP/UIP (45%). Among all RA-ILD patients, 16 (40%) showed honeycomb formation on follow-up CT (median time between initial and last follow-up CT was 4.7 years). Patient characteristics and prognosis were not significantly different between the Non-honeycomb and Honeycomb groups. However, Kaplan-Meier survival curve for the time from the date of honeycomb formation to death showed a poor median survival time of 3.2 years. CONCLUSIONS A certain number of patients with RA-ILD developed a honeycomb pattern during long-term follow-up, regardless of whether they had UIP or NSIP. Prognosis in the patients with characteristics of both progressive ILD and honeycomb formation could be poor. Although radiological findings over the disease course and clinical disease behavior in RA-ILD are heterogenous, clinicians should be alert to the possibility of progressive disease and poor prognosis in patients with RA-ILD who form a honeycomb pattern during follow-up observation.

Abstract
OBJECTIVE To assess the influence of abnormal cord insertion (CI) detected by first trimester ultrasonography on the development of twin-to-twin transfusion syndrome (TTTS) in monochorionic diamniotic (MCDA) twins. METHOD In this retrospective cohort study, consecutive patients with MCDA twins who underwent fetal ultrasound screening in the first trimester between January 2011 and January 2017 were enrolled. The CI sites were evaluated between 11 + 0 and 13 + 6 weeks' gestation. All twin pairs were assigned to the abnormal CI group (twin pair with velamentous cord insertion (VCI) and/or marginal cord insertion (MCI) in one or both twins) or the normal CI group (twin pair with both normal CI). The relationships of adverse outcomes in two groups were analyzed. RESULTS A total of 109 MCDA twin pairs were examined; 15 cases were classified into the abnormal CI group and 94 cases into the normal CI group. The incidence of TTTS was significantly higher in the abnormal than in the normal CI group (26.7% vs 7.45%, P = .04). In patients who developed TTTS, all donors had VCI. CONCLUSION Ultrasound evaluation of abnormal CI at 11 + 0 to 13 + 6 weeks' gestation in MCDA twins is valuable in the assessment of the risk for TTTS.

Abstract
Background Interstitial lung disease (ILD) is associated with high morbidity and mortality in rheumatoid arthritis (RA). Although usual interstitial pneumonia (UIP) pattern was reported as a poor prognostic factor, in clinical practice, we often cannot classify high-resolution computed tomography (HRCT) patterns specifically as UIP or nonspecific interstitial pneumonia (NSIP). This study of RA-ILD aimed to elucidate prognosis by using our modified HRCT pattern classification according to the latest guideline on idiopathic pulmonary fibrosis (IPF). Methods We analysed the medical records of 96 consecutive patients diagnosed as having RA-ILD. The modified HRCT classifications were defined as definite UIP, probable UIP, indeterminate for UIP (i.e., early UIP or NSIP/UIP), NSIP, organizing pneumonia (OP), NSIP+OP, and unclassifiable. Predictors of prognosis were determined using Cox regression models. Results Our RA-ILD cohort included definite UIP (21%), probable UIP (20%), indeterminate for UIP (30%) including NSIP/UIP (27%), alternative diagnosis (29%) including NSIP (14%), and other patterns. Interrater agreement for HRCT pattern was good (κ=0.75). Multivariate analysis showed that older age, history of acute exacerbation, and radiological honeycombing were negative prognostic factors of mortality. Conclusions NSIP/UIP pattern of indeterminate for UIP was the major pattern in RA-ILD. Although classifications of HRCT patterns were not related to survival, the presence of radiological honeycombing could be a useful predictor of poor prognosis, and acute exacerbation of ILD can seriously impact patient survival regardless of the presence of a UIP or indeterminate for UIP pattern. Our modified HRCT classification based on the latest IPF guideline might be useful to assess appropriate strategies of diagnosis in future RA-ILD studies, and radiological honeycombing could better predict poor prognosis rather than HRCT pattern.

Abstract
Pulmonary tumor thrombotic microangiopathy (PTTM) is rare but should be considered as a possible diagnosis in patients with cancer. In this case, PTTM induced by lung cancer was more accurately diagnosed using cell block immunohistochemistry of pulmonary microvascular cytology (PMC) because we could confirm that lung adenocarcinoma was the origin of PTTM by the positive result of TTF-1 for atypical cells in PMC. The PMC procedure was minimally invasive and safer than lung biopsy. We believe that the cell block technique of PMC should be considered as one diagnostic option in PTTM.

Abstract
Background Nintedanib is a tyrosine kinase inhibitor that efficiently slows the progression of idiopathic pulmonary fibrosis (IPF) and has an acceptable tolerability profile. In contrast, immune checkpoint inhibitors (ICIs) such as programmed death 1 and programmed death ligand 1 inhibitors have shown clinical activity and marked efficacy in the treatment of non-small cell lung cancer. However, it is unclear whether nintedanib reduces the risk of ICI-induced pneumonitis in IPF. Case presentation A 78-year-old man with squamous cell lung carcinoma in IPF underwent second-line treatment with pembrolizumab. He was diagnosed as having pembrolizumab-induced pneumonitis after two cycles. He was administered prednisolone (PSL) and then improved immediately. Thereafter, his lung cancer lesion enlarged despite treatment with TS-1. Atezolizumab was then administered as 4th-line chemotherapy, but he immediately developed atezolizumab-induced pneumonitis after 1 cycle. The re-escalated dosage of PSL improved the pneumonitis, and then nintedanib was started as additional therapy. Under careful observation with nintedanib, atezolizumab was re-administered on day 1 of an every-21-day cycle. After three cycles, it remained stable without exacerbation of drug-induced pneumonitis. Conclusion This case indicates the possibility that the addition of nintedanib to ICI therapy might prevent drug-induced pneumonitis or acute exacerbation of IPF. However, whether anti-fibrotic agents such as nintedanib are actually effective in preventing ICI-induced pneumonitis in ILD remains unknown and additional research is greatly needed to identify effective therapies for ILD combined with lung cancer.

Abstract
OBJECTIVES The aim of this study was to establish the frequency and associations of single umbilical artery (SUA) diagnosed until the first vs second or third trimester. METHODS A retrospective cohort study was conducted on singleton pregnancies at a tertiary perinatal center. All women underwent both the first and second trimester scans in which the number of arteries in the umbilical cord was routinely documented. SUA was classified as aplastic type when the diagnosis was made in the first trimester and as occlusion type when diagnosed in the second or third trimester. Adverse perinatal outcome was calculated as occurrence of fetal death, birthweight centile < 10th , or Apgar score at 5 minutes < 7. RESULTS A total of 8675 women underwent ultrasound examinations during the study period. Of the 32 SUA cases, 17 (0.2%) were of the aplastic type and 15 (0.2%) of the occlusion type. Congenital anomalies were more in aplastic than in occlusive SUA (58.8% vs 20%, .043). The occlusive SUA had higher postnatal coiling index (0.3 vs 0.2, .034) and diagnosis of hypercoiled cord (46.7% vs 5.9%, .013) than the aplastic type. CONCLUSIONS The different gestational age at diagnosis and coiling characteristics suggest two types of SUA, namely, aplastic and occlusion types, which are associated with differences in perinatal outcomes.

Abstract
Objectives: To evaluate the usefulness of color Doppler in fetal cardiac ultrasound screening in the second trimester.Methods: Fetuses who underwent ultrasound screening at 18-20 weeks' gestation at Showa University Hospital between 2011 and 2016 were evaluated. After delivery, neonatal congenital heart abnormalities were reviewed and compared with the antenatal ultrasound findings. Since 2014, we have added color Doppler to the routine B mode evaluation of the fetal heart. Congenital heart diseases (CHDs) found antenatally and postnatally were compared before and after protocol alternation. Medical records of all fetuses who underwent ultrasound screening at 18-20 weeks' gestation at Showa University Hospital between 2011 and 2016 were retrospectively reviewed.Results: There were 47 cases of CHDs confirmed postnatally. The detection rates of CHDs were 45.0% (9/20) in 2011-2013 and 55.6% (15/27) in 2014-2016. In 2011-2013, cases with antenatal diagnosis showed obvious abnormal findings of three-vessel view and four-chamber view with the B mode. In 2014-2016, the detection rate of isolated ventricular septal defect (VSD) was elevated from 10 to 42.9% using color Doppler.Conclusions: In this study, color Doppler improved the detection rate of CHDs. Color Doppler could give us additional information on blood flow although the canal or vessel is too small to detect morphological changes in the second trimester. It might be a useful tool for screening of CHDs with stenosis, regurgitation, and shunt that are difficult to detect by only the B mode in the second trimester.

Abstract
Objectives: To clarify whether early-onset fetal growth restriction (EO-FGR) could be distinguished from late-onset (LO)-FGR using ultrasonographic evaluations of the uterine artery (UtA) Doppler indices and the three-dimensional (3D) ultrasound placental volume (PV) in the first trimester.Methods: Subjects with 1362 singleton pregnancies who underwent an ultrasound scan at 11-13 weeks were enrolled prospectively. The UtA Doppler and PV indices in cases with EO-FGR (<32 weeks at diagnosis) and LO-FGR (≥32 weeks at diagnosis) later in pregnancy were compared with the control group.Results: Twenty-eight EO-FGR, 73 LO-FGR, and 1261 control groups were analyzed. The crown-rump length (CRL) and PV were smaller in both EO and LO-FGR groups than in the control group. The UtA resistance index (RI) Z-score was significantly higher in the EO-FGR group than in the control group (0.723 versus 0.086, p < .001), but did not differ between LO-FGR and the control group. The area under the receiver operating characteristics curve for the prediction of EO-FGR by combining the uterine artery resistance index (UtA-RI) and CRL was 0.760 (95% CI: 0.654-0.865). The detection rate for EO-FGR was 45.8%, with a 10% false-positive rate.Conclusions: Both EO- and LO-FGR are associated with a small CRL in the first trimester. High UtA-RI is associated with EO-FGR, while a small maternal height and PV are associated with LO-FGR.

Abstract
We herein report the first case, to our knowledge, of tracheobronchial ulcer with anti-melanoma differentiation-associated gene 5 (anti-MDA 5) antibody-positive interstitial lung disease (ILD). A 53-year-old man complained of shoulder and wrist pain and was suspected of having polymyalgia rheumatica at another hospital. Thereafter, treatment with prednisolone was started. Although his arthralgia improved, he suffered from progressive dyspnea on exertion and an abnormal shadow was noted on chest X-ray, so he was transferred to our hospital. Chest computed tomography scan revealed ground-glass opacities and intralobular septal thickening. We diagnosed him as having clinically amyopathic dermatomyositis associated with ILD based on the specific skin findings and elevated anti-MDA 5 antibody titer. Fiberoptic bronchoscopy showed ulcerations of the trachea and bronchus. Treatment with dose increments of prednisolone combined with other immunosuppressive drugs resulted in improvement of his respiratory condition and tracheobronchial lesions. Clinicians should be aware that tracheobronchial ulcers can be associated with anti-MDA 5 antibody-positive interstitial lung disease.

Abstract
Purpose: To assess whether the ultrasonographic measurement of the inferior vena cava (IVC) diameter in postpartum women is a useful parameter in evaluating the actual blood loss during delivery due to massive postpartum hemorrhage. Materials and methods: In postpartum women with blood loss ≥500 g, abdominal ultrasonography was performed 1 hour after delivery. The IVC diameter was measured during inspiration (IVCi) and expiration (IVCe). The maternal heart rate, blood pressure, and shock index (heart rate/systolic blood pressure) were also measured. The predictive value of these parameters for severe anemia (hemoglobin <7.0 g/dL) a day after delivery was evaluated via receiver operating characteristic (ROC) analyses. Results: Seven patients with severe anemia and 77 controls were included in the analysis. The area under the curve (AUC) for IVCi (0.905) and IVCe (0.926) was higher than that for the shock index (0.890), heart rate (0.874), or systolic blood pressure (0.752). Among the examined parameters, the best sensitivity was achieved by IVCe and systolic blood pressure (71.4%). Conclusions: The ultrasonographic measurement of the IVC diameter was found to be the most useful parameter in evaluating the actual maternal blood loss after delivery.

Abstract
Abstract
Background: Concerns still remain about lower sentinel node (SN) detection and higher false-negative rates (FNR) in breast cancer patients treated with neoadjuvant chemotherapy (NAC), especially those who are clinically node-positive before NAC. It is necessary to analyze the validity of sentinel node biopsy (SNB) after NAC and evaluate whether the SN identification rate and FNR for clinically N0 (cN0) patients after NAC would be acceptable or not in order to omit axillary lymph node dissection (ALND).
Objectives and methods: We identified SN by radioisotopic methods followed by completion of ALND in cN0 patients after NAC from 2013 to 2016 as part of a clinical research study (SNB group, N=68) to analyze the accuracy of SNB, and retrospectively investigated the prognosis of patients treated with NAC from 2006 to 2012 (control group, N=92) to evaluate whether the validity of SNB would be acceptable or not.
Results: Mean patient ages in the SNB group and control group were 51.0 years and 49.5 years, respectively (p=0.17), and the distribution of intrinsic subtypes was not significantly different between the two groups. The numbers of cN1≤ before NAC in the SNB group and control group were 85.5% (57/68) and 80.4% (74/92), respectively (p=0.58), and the pathological complete response rates were 25.0% (17/68) and 19.6% (18/92), respectively (p=0.41). Lymphoscintigraphy using 99mTc-phytate acid was performed in the SNB group, and hot spots were detected at the ipsilateral axilla in 62 of 68 (91.2%) patients, in all of whom SNs could be identified by using a gamma-probe. The FNR, which indicates no metastasis in SNs and metastasis in non-SN, was 5.9% (4/68). Among these four patients, three were of the luminal type while one was triple negative. The number of patients without metastasis in both SN and non-SN, which are candidates for omission of ALND, was 26 of 68 (38.2%). They included eight of nine HER2-enriched patients and six of 13 luminal-HER2 patients. Conversely, there were no false-negative cases in these subtypes. Moreover, all SNs were identified even if there were metastases in SNs. Regarding the prognosis of the control group, the 10-year disease free survival of post-NAC N0 (ypN0) (52/92, 56.5%) and ypN1≤ (40/92, 43.5%) were 80.7% and 61.2%, respectively (p=0.08); in addition, the 10-year overall survival of yN0 and ypN1≤ were 90.4% and 72.6% (p=0.26). Thus, the prognosis of ypN1≤ was not significantly inferior to that of ypN0. If omission of ALND were performed for false negative cases, then the risk of axillary relapse would be a concern. However, these data indicate the possibility that 5.9% of FNR as shown in the SNB group would not have much influence on prognosis.
Conclusion: The accuracy of SN detection by radioisotopic methods for cN0 breast cancer after NAC was not maintained like that for -early breast cancer although it was better than the results of previous studies. However, there were no false-negative cases in HER2-enriched and luminal-HER2 subtypes, which could be potential candidates for omission of ALND. In addition, omission of ALND for false-negative patients would have less influence on the prognosis.

Abstract
OBJECTIVE To investigate, how causes of intrauterine fetal death (IUFD) have changed in recent years with the advancement of prenatal diagnosis at a single perinatal center in Japan. METHODS Medical records were retrospectively reviewed for all cases of IUFDs that occurred between 2001 and 2014. The most commonly associated causes of fetal deaths were compared between 2001-2007 and 2008-2014. RESULTS The number of IUFD after 20 weeks' gestation/all deliveries in our center was 38/6878 cases (0.53%) in 2001-2007 and 35/7326 (0.48%) in 2008-2014. The leading cause of IUFD in 2001-2007 was fetal abnormalities (43.2%), the prevalence of which was only 8.6% in 2008-2014 (P<0.01). Meanwhile, the prevalence of umbilical cord abnormalities was relatively increased from 30.0% in 2001-2007 to 54.5% in 2008-2014 (P=0.06). In 2001-2007, chromosomal abnormalities were frequently observed (56% of IUFDs due to fetal abnormalities). Hyper-coiled cord (HCC) and umbilical ring constrictions were the most frequent cause of IUFD in both periods. The relatively decreased prevalence of IUFD due to velamentous cord insertion and umbilical cord entanglement, HCC and umbilical cord constriction was increased. CONCLUSIONS The prevalence of IUFD due to fetal abnormalities was reduced, but IUFD associated with umbilical cord abnormalities tended to increase relatively.

Abstract
AIM The aim of this study was to evaluate the effect of long-term use of tocolytic agents to prevent preterm delivery and improve perinatal outcome. METHODS A historical cohort study was performed in a single perinatal center. The maternal characteristics, frequency of preterm labor and prescribed dose of tocolytic agents were compared before and after changing the management protocol for threatened premature delivery. RESULTS A total of 1548 deliveries were carried out before changing the protocol for the use of tocolytic agents for threatened premature delivery and 1444 deliveries afterwards. There was no significant difference in the maternal characteristics before and after the revision except for maternal age. The total number of ritodrine hydrochloride ampules used was reduced from 4654 to 514, and the total vials of magnesium sulfate used were reduced from 1574 to 193, but perinatal outcomes, such as rate of preterm birth, neonatal weight, and rate of NICU hospitalization were not different between the groups. CONCLUSION There was no significant change in the frequency of preterm delivery before and after changing of the protocol for threatened premature delivery. Because a decrease in the given dose of tocolytic agents did not affect the timing of delivery and neonatal outcomes, long-term tocolysis in patients with threatened premature delivery should be restricted to prevent maternal and fetal adverse side-effects.

Abstract
The use of intra-aortic balloon occlusion (IABO) could be effective in achieving the quick control of bleeding in emergency settings and in supporting the provision of safe radical treatment through resuscitative endovascular balloon occlusion of the aorta (REBOA). We herein report our experience of a patient with life-threatening postpartum hemorrhage after cesarean section who was successfully treated by hysterectomy with IABO without fluoroscopy. We believe that this procedure is very useful and safe, and that it should be considered as one of methods for controlling bleeding in patients with life-threatening postpartum hemorrhage.

Abstract
OBJECTIVE Hemorrhagic shock is a relatively common occurrence in the postpartum period. In our hospital, we performed abdominal ultrasonography using the focused assessment with sonography for obstetrics (FASO) technique (a modified version of FAST). The aim of the present study was to determine the reference values for the ultrasonographic findings to establish the criteria for the diagnosis of a postpartum hemorrhage and severe shock using the FASO. METHODS The present prospective cohort study included all postpartum women who vaginally delivered singleton infants. Abdominal ultrasonography was performed after delivery. The observation points of ultrasonography were as follows: (1) the diameter of the intrauterine cavity, (2) the pouch of Douglas, (3) Morison's pouch, (4) between the spleen and kidney, and (5) the diameter of the inferior vena cava. RESULTS One hundred and eighty-two postpartum women were included in this study. The mean uterine cavity was 9.8 ± 7.3 mm. An echo-free space in the pouch of Douglas was observed in three cases, in one case in Morison's pouch, and not observed between the spleen and kidney. A negative correlation was found between the volume of bleeding and IVCi (p = 0.0008, r(2)= -0.061) and IVCe (p < 0.0001, r(2)= -0.106). CONCLUSIONS The present study establishes criteria that can be used to diagnose a postpartum hemorrhage or severe shock using the FASO.

Abstract
The levels of soluble intercellular adhesion molecule-1 (sICAM-1) have been reported to increase in patients with idiopathic pulmonary fibrosis. However, the utility of sICAM-1 has not been reported in detail. The aim of this study was to investigate whether sICAM-1 was a useful biomarker for stable idiopathic pulmonary fibrosis (IPF) and early phase of acute exacerbation of IPF. The patients who were diagnosed with IPF between 2013 and 2015 were enrolled. The levels of sICAM-1 and other interstitial pneumonia markers were measured. In this study, 30 patients with stable IPF and 11 patients with acute exacerbation of IPF were collected. Mean sICAM-1 levels were 434 ± 139 ng/mL for the stable phase of IPF, 645 ± 247 ng/mL for early phase of acute exacerbation of IPF, 534 ± 223 ng/mL for connective tissue disease-associated interstitial pneumonia, 221 ± 42 for chronic obstructive pulmonary disease, and 150 ± 32 ng/mL in healthy volunteers. For the stable phase of IPF, sICAM-1 levels correlated with Krebs von den Lungen-6 (KL-6) (r value: 0.41; p value: 0.036). Mean sICAM-1 levels were significantly higher in patients with early phase of acute exacerbation of IPF than with stable phase of IPF (p = 0.0199). Multiple logistic analyses indicated that the predictors for early phase of acute exacerbation of IPF were only sICAM-1 and C-reactive protein (odds ratio: 1.0093; 1.6069). In patients with stable IPF, sICAM-1 levels correlated with KL-6; sICAM-1 might be a predictive indicator for prognosis. In the early phase of acute exacerbation of IPF, sICAM-1 might be more useful for diagnosis than other interstitial pneumonia markers.

Abstract
OBJECTIVE To clarify which types of cervical polyp removed during the first and second trimester are associated with the risk of spontaneous abortion and preterm delivery. METHODS Pregnant females who underwent attempted polypectomy of cervical polyps during pregnancy and delivered singleton infants between 2005 and 2011 were evaluated. The clinical courses and outcomes of preterm delivery after polypectomy stratified according to the pathologic diagnosis of the polyps were retrospectively reviewed. The removed polyps were classified into decidual polyps and endocervical polyps. RESULTS The pathological diagnoses included 41 decidual polyps and 42 endocervical polyps. No malignant polyps were found. The removal of decidual polyps during pregnancy carried a higher risk of spontaneous abortion (12.2% versus 0%, p = 0.026) and preterm delivery (34.2% versus 4.8%, p = 0.001) than that of endocervical polyps. According to the multivariate logistic regression analysis, risk factors for preterm delivery before 37 weeks' gestation were the presence of decidual polyps and a history of preterm delivery. CONCLUSIONS The risk of abortion and preterm delivery associated with polypectomy during pregnancy is greater in patients with decidual polyps. It might be safer not to remove cervical polyps during pregnancy, except in cases in which the polyps are suspected to be malignant.
