Abstract
BACKGROUND The number of breast cancer patients of childbearing age has been increasing. Therefore, we investigated the characteristics and the childbearing status of the patients who received systemic therapy for breast cancer during their childbearing age to better understand the clinical impact of childbirth. METHODS Female patients with breast cancer younger than 40 years old who underwent surgery and received perioperative systemic therapy from 2007 to 2014 were included in this study. We compared the characteristics of patients with and without childbirth after treatment. RESULT Of 590 patients, 26 delivered a child, and 355 did not bear a child during the median observation period of 8.1 years, whilst 209 had unknown childbirth data. The childbirth group had a lower mean age at surgery (32.2 vs. 35.1, P < 0.001). The proportion of patients who desired childbirth and used assisted reproductive technology was significantly higher in the childbirth group (65.4 vs. 23.9% and 45.2 vs. 5.1%, respectively, P < 0.001). The patients in the childbirth group had significantly less advanced disease (P = 0.002). In the childbirth group, the age at childbirth was significantly older in patients who received combined endocrine therapy and chemotherapy (40.8 years) than in patients who received either alone (endocrine therapy: 36.9 years, chemotherapy: 36.7 years, P = 0.04). However, survival was not different between those with and without childbirth. CONCLUSION It is critical to recognize the desire for childbirth in patients with breast cancer who are receiving systemic therapy and to provide them with necessary fertility information before treatment to support their decision-making.

Abstract
BACKGROUND Higher body mass index (BMI) is associated with worse prognosis in pre- and postmenopausal patients with breast cancer (BC). However, there is insufficient evidence regarding the optimal adjuvant endocrine therapy for obese premenopausal women with hormone receptor (HR)-positive BC. AIM To evaluate the impact of obesity and adjuvant endocrine therapy on prognosis in premenopausal patients with BC. METHODS AND RESULTS We retrospectively reviewed the medical record of premenopausal women who received curative surgery for clinical stage I-III HR-positive BC from 2007 to 2017. Patients were classified into five groups according to BMI: underweight (UW), normal weight (NW), obese 1 degree (OB1), obese 2 degree (OB2), and obese 3 degree (OB3) categories. The primary analysis was a comparison of BC-specific survival (BCSS) according to BMI (UW/NW vs. OB1-3) and adjuvant endocrine therapy (with or without ovarian function suppression [OFS]). Of 13 021 patients, the data of 3380 patients were analyzed. BCSS in OB1-3 patients was significantly worse than that in patients with UW/NW (hazard ratio [HR] 2.37; 95% confidence interval [CI], 1.40-4.02: p = .0009). In OB1-3 patients who received tamoxifen (TAM), BCSS was significantly worse than that in UW/NW patients (p = .0086); however, a significant difference was not shown in patients who received TAM and OFS (p = .0921). CONCLUSION High BMI was associated with worse prognosis in premenopausal patients with HR-positive BC who received adjuvant TAM. The role of OFS as adjuvant endocrine therapy remains unclear, and further studies are required to explore the adequate management of obese premenopausal patients.

Abstract
OBJECTIVES Accumulating evidence from cross-sectional studies suggests that the serum creatinine-to-cystatin C ratio (CCR) may be a useful biomarker for sarcopenia. This study aimed to assess the cross-sectional and longitudinal associations of CCR with sarcopenia and its parameters in community-dwelling older adults. DESIGN Cross-sectional and longitudinal study. SETTING AND PARTICIPANTS This 6-year prospective cohort study included the repeated measurement data from 1,253 Japanese residents (662 males and 591 females) aged ≥65 years who underwent medical checkups in Kusatsu and Hatoyama, Japan. A total of 4,421 observations were collected. MEASUREMENTS The CCR was grouped into quartiles by sex (Q1-Q4) using Q4 as the reference category. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 algorithm. Skeletal muscle mass index (SMI) measured using segmental multifrequency bioelectrical impedance analysis, handgrip strength (HGS), usual gait speed (UGS), and maximal gait speed (MGS) were measured repeatedly as sarcopenia parameters. The association of the CCR with changes in sarcopenia, SMI, HGS, UGS, and MGS during the 6-year period were analyzed using a generalized linear mixed-effects model. RESULTS The prevalence of sarcopenia at baseline was 13.1% (11.9% in males and 14.5% in females). In a cross-sectional analysis, the CCR quartile was inversely associated with sarcopenia and was positively associated with SMI, HGS, and MGS (P for trend < 0.001). In a longitudinal analysis during the 6 years, a significant increase in sarcopenia in Q2 (B = 1.1% point/year; P = 0.026 for group-by-time interaction) and significant declines in SMI (B = -0.01 kg/m2/year; P = 0.044 for group-by-time interaction) and MGS (B = -0.008 m/sec/year; P = 0.041 for group-by-time interaction) in Q1 were observed compared with Q4. However, the dose-response relationship was significant only for MGS (P = 0.033 for trend). No significant group-by-time interaction was observed for HGS. CCR was not significantly associated with UGS either cross-sectionally or longitudinally. CONCLUSIONS CCR is a useful biomarker regarding the status of sarcopenia. It may be used for sarcopenia screening even in older adults whose physical function is difficult to assess. However, further longitudinal studies are needed to determine whether CCR can be a predictor of future sarcopenia.

Abstract
BackgroundPain in rheumatoid arthritis (RA) is considered to be linked with non-inflammatory factors, including physical disabilities, psychiatric disorders, and pain catastrophizing (PC) (1.ObjectivesWe investigated the role of PC in the possible link between physical disabilities and psychiatric disorders in RA patients in a non-inflammatory condition.MethodsIn this cross-sectional study, a total of 81 RA patients in a non-inflammatory condition were included; all patients had serum C-reactive protein levels <0.5 mg/dL, without any inflammatory joints. We examined the demographic and clinical data and administered the pain visual analog scale (VAS), the pain catastrophizing scale (PCS), the Health Assessment Questionnaire Disability Index (HAQ-DI), and the patient version of the Brief Scale for Psychiatric Problems in Orthopedic Patients (pBS-POP). A series of multivariate-adjusted multiple regression analyses were performed to examine the associations between PC and pain intensity, physical disabilities, and psychiatric disorders.ResultsWe found associations between all the above-mentioned variables in separate models associated with HAQ-DI, pBS-POP, and PCS scores. However, in the model associated with pain VAS, the PCS score (β=0.34, p=0.0073) emerged as the only variable showing statistically significant association.ConclusionPC is associated with pain in RA patients in a non-inflammatory condition, and this association may be mediated through pathways involving physical disabilities and psychiatric disorders.References[1]Edwards RR, Giles J, Bingham CO, Campbell C, Haythornthwaite JA, Bathon J (2010) Moderators of the negative effects of catastrophizing in arthritis.

Abstract
Abstract
Background: Obesity is related to poor prognosis in pre- and postmenopausal patients with breast cancer. However, there is insufficient evidence regarding the optimal adjuvant hormone therapy for obese premenopausal women with hormone receptor-positive breast cancer. We examined the impact of ovarian function suppression (OFS) on the prognosis of obese women with primary hormone receptor-positive breast cancer. Methods: We retrospectively reviewed premenopausal women who received curative surgery for clinical stage I-III hormone receptor (HR)-positive breast cancer at the Cancer Institute Hospital of the Japanese Foundation for Cancer Research from January 2007 to December 2017. All patients were classified into five groups according to body mass index (BMI): underweight (UW), BMI <18.5 kg/m2; normal weight (NW), 18.5-24.9 kg/m2; obese 1 degree (OB1), 25.0-29.9 kg/m2; obese 2 degree (OB2), 30.0-34.9 kg/m2; and obese 3 degree (OB3), ≥35 kg/m2. The primary analysis was a comparison of breast cancer-specific survival (BCSS) according to BMI (UW/NW vs. OB1-3) and adjuvant hormonal therapy (with or without OFS). Secondary endpoints included overall survival (OS). Results: Overall, the total number of patients was 13,021 and the data of 3,380 patients were analyzed, which included patients who received adjuvant tamoxifen (TAM) without OFS (n = 1,836) or with OFS (n = 670). The median follow-up duration was 5.9 years (range, 0.2-12.9). The numbers of patients with UW, NW, OB1, OB2, and OB3 were 404 (12%), 2,482 (73%), 399 (12%), 78 (2%), and 17 (1%), respectively. Obesity was significantly associated with higher stage of breast cancer (p <0.0001). Nuclear grade of breast cancer in OB1-3 patients was significantly higher than that in UW/NW patients (p = 0.0323). BCSS in OB1-3 patients was significantly worse than that in patients with UW/NW (hazard ratio [HR] 2.37; 95% confidence interval [CI], 1.40-4.02: p = 0.0009). In OB1-3 patients who received TAM as adjuvant hormone therapy, BCSS was significantly worse than that in UW/NW patients (p = 0.0086); however, a significant difference was not shown in patients who received TAM and OFS (p = 0.0921). Multivariate analysis revealed that OB3 was an independent prognostic factor compared with NW in patients with stage II/III breast cancer (p = 0.0162).Conclusion: High BMI was associated with worse prognosis in premenopausal patients with HR-positive breast cancer. The negative impact of obesity might be canceled by adding OFS to TAM as adjuvant hormone therapy. Further studies are required to explore the adequate management of obese premenopausal patients.

Abstract
OBJECTIVES We aimed to investigate whether combination assessment of phase angle (PhA) and skeletal muscle index (SMI), was a possible predictor of physical function at discharge from the hospital in patients with acute stroke. RESEARCH METHODS AND PROCEDURES In this retrospective cohort study that was conducted from May 2020 and July 2021, we determined PhA and SMI using bioimpedance analysis (BIA) in patients with acute stroke. Patients were classified as normal, low PhA + SMI group, pre-sarcopenia (low SMI only), and dynapenia (low PhA only) using cut-off points (men: SMI < 7.0 kg/m2, PhA < 4.05 degrees; women: SMI < 5.7 kg/m2, PhA < 3.55 degrees). The main outcome was physical function based on functional independence measure motor (FIM-motor) score at discharge. Multiple regression analysis was used to determine the association between low PhA + SMI and FIM-motor score. RESULTS We included 244 patients (161 men; mean age, 73.9 years). low PhA + SMI was found in 21 (8.6%) patients. Multiple regression analysis showed that low PhA + SMI was independently associated with the FIM-motor score at discharge (β= -0.099, 95%CI: -0.193,-0.005, p = 0.039). The PhA cutoff values for determining good functional results using receiver operating characteristic (ROC) curves were 5.36 for men (sensitivity = 0.769, specificity = 0.586, area under the curve [AUC] = 0.682), and 3.85 for women (sensitivity = It was 0.881, specificity = 0.481, AUC). Further, pearson correlation coefficient showed that PhA was significantly related to FIM-motor score in patients with mild or moderately severe stroke (mild: r = 0.472, p < 0.001; moderate: r = 0.524, p < 0.001). CONCLUSIONS Combination of low PhA and SMI values at baseline, was an independent predictor of physical function at discharge in patients with acute stroke. The findings highlighted the importance of measuring PhA and SMI using BIA in patients with acute stroke.

Abstract
Abstract
Background
While some studies have found an association between built environments and physical function, it is unclear whether living in a hilly area is associated with poor physical function among older adults, and whether this association varies by car driving status. This cross-sectional study investigated the association between hilliness and physical function in community-dwelling older adults and whether it varied according to their car driving status.
Methods
Data were collected from 633 participants aged 60 years and older living in Okinoshima Town, Shimane prefecture, Japan, in 2018. Physical function was objectively assessed; < 1.0 m/s was defined as poor walking speed, and hilliness was measured by mean land slope within a 1000-meter network buffer zone around each participant's home using geographic information system. Logistic regression examined whether hilliness was associated with poor walking speed adjusted for sex, age, body mass index, current smoking, current alcohol consumption, exercise habits, current chronic disease, and living arrangements. A stratified analysis by car driving status was also conducted.
Results
A total of 159 (25.1%) participants had poor walking speed. After adjusting for all confounders, hilliness was positively associated with poor walking speed (OR = 1.07, 95% CI, 1.02-1.12). The stratified analysis by car driving status showed that living in a hilly area was positively associated with poor walking speed among non-drivers (OR = 1.10, 95% CI, 1.03-1.17), though there were no associations among drivers (OR = 1.00, 95% CI 0.92-1.08).
Conclusions
Our study found that a hilly environment was associated with poor walking speed in community-dwelling older adults in Japan. Moreover, car driving status potentially modified the relationship between living in a hilly environment and poor walking speed.
Key messages
Older adults living in a hilly environment were more likely to have poor walking speed, compared to those living in less hilly area. The stratified analysis by car driving status showed that non-driving older adults living in a rural hilly environment may be at high risk for poor physical function.

Abstract
Abstract
Background
Although neighborhood environmental factors have been found to be associated with cognitive decline, few longitudinal studies have focused on their effect among older adults living in rural areas. This longitudinal study aimed to investigate the effect of neighborhood environmental factors on cognitive decline among rural older adults.
Methods
The data of 503 older adults aged > 60 years who were living in Unnan City in Japan and had participated in two surveys conducted between 2014 and 2018 were analyzed. Cognitive function was assessed using the Cognitive Assessment for Dementia, iPad version 2. Elevation, hilliness, residential density, and proximity to a community center were measured using geographic information system. Logistic regression examined the effect of each neighborhood environmental factor (in quartiles: Q1-Q4) on cognitive decline.
Results
A total of 57 (11.3%) participants demonstrated a decrease in cognitive function at follow up. Elevation (Odds ratio (OR): 3.37, 95% Confidence Interval (CI): 1.11-10.20 for Q3 vs. Q1; OR: 5.43, 95% CI: 1.89-15.56 for Q4 vs. Q1) and hilliness (OR: 3.45, 95% CI: 1.46-8.11 for Q4 vs. Q1) were associated with a higher likelihood of cognitive decline. Residential density and distance to a community center were not associated with cognitive decline.
Conclusions
Elevated and hilly environments may increase risk of cognitive decline among rural older adults.
Key messages
Residents in mountainous regions tend to have limited accessibility to various living centers. Those who live in elevated and hilly areas within the mountainous regions may have further limited accessibility and availability of locations where they can interact with others.

Abstract
Abstract
Background
Hypochloremia is associated with a poor prognosis of heart failure (HF) patients. This phenomenon is sustained even in HF with preserved ejection fraction (HFpEF). Serum chloride level is known to be affected by serum renin secretion; however, this relationship is one of the least investigated field in HF patients. Renin-angiotensin system (RAS) inhibitor is recommended as a first-line medication for HF patients with reduced left ventricular ejection fraction, but no prior studies of RAS inhibitors have achieved to improve the prognosis of HFpEF patients.
Purpose
We investigated the relationship between baseline serum chloride level and the prognostic impact of RAS inhibitor in HFpEF patients.
Methods
This is an observational study including 1,913 consecutive patients who admitted to hospital due to worsening of HF and discharged alive in a single university hospital. After excluding patients who received regular hemodialysis and whose left ventricular ejection fraction were under 50%, 506 HFpEF patients were ultimately analyzed. They were categorized into tertiles by serum chloride levels at discharge (T1: −100 mEq/L, T2: 101–104 mEq/L, T3: 105- mEq/L), and patients in each category were further divided into subgroups depending on the prescription of RAS inhibitor at discharge (RAS inhibitor group and Non-RAS inhibitor group). The primary endpoint of this study was death from any cause.
Results
During the observation period with 479 days of median follow-up, 77 (15.2%) died. Patients in the RAS inhibitor group had significantly better prognosis than those in the Non-RAS inhibitor group in T1 category (Log-rank: p=0.003, Figure). In contrast, there was no statistical difference in the mortality between the RAS inhibitor group and Non-RAS inhibitor group in T2 and T3 categories (Log-rank: p=0.15, p=0.81, respectively, Figure). Multivariate Cox regression analysis in T1 category revealed that taking RAS inhibitor at discharge was independently associated with a lower mortality rate, even after the adjustment of diverse covariates (hazard ratio: 0.40, 95% confidence interval: 0.20–0.80).
Conclusion
In this observational study, the administration of RAS inhibitor was associated with an improved prognosis of HFpEF patients only in low serum chloride level at discharge. Therapeutic strategy focusing on the chloride level may be one of the promising options to find the light on a unintervenable prognosis of HFpEF.

Abstract
Abstract
Background
As the first-line medications, renin-angiotensin-aldosterone system inhibitor (RAASi) and β-blocker provide prognostic benefits in patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). However, the negative inotropic effect of these drugs may destabilize the hemodynamics during hemodialysis (HD) and become prognostically controversial in patients receiving regular HD. Indeed, prior studies have reported the cancellation of the favorable prognostic effects of RAASi and β-blocker in patients with HD. However, it is totally unknown whether the guideline-directed medical therapy affects the prognosis in HF patients receiving regular HD.
Purpose
We aimed to evaluate the prognostic impact of RAASi and β-blocker on the cardiovascular (CV) events in HF patients on regular HD.
Methods
This observational study initially included 1,930 consecutive patients who were hospitalized due to HF and discharged alive. Of these, 151 patients who received regular HD were ultimately analyzed. They were classified into 3 groups depending on the prescribing medications at discharge; patients who received none of RAASi or β-blocker (None group: N=19), either RAASi or β-blocker (Either group: N=56), and both RAASi and β-blocker (Both group: N=76). The primary endpoint was a composite of CV death and readmission due to HF.
Results
During the observation period of median 501 (interquartile range: 197–954) days, the primary endpoint occurred in 61 patients (40%). Kaplan-Meier analysis showed the highest rate of composite endpoint in the None group (log-rank for trend: p<0.001, Figure). After adjusting for covariates of age, sex, LVEF, and systolic blood pressure and heart rate at discharge, the hazard ratio (HR) for a composite endpoint was significantly lower in the Either group or Both group than that in the None group [HR: 0.19, 95% confidence interval (CI): 0.08–0.45; HR: 0.16, 95% CI: 0.06–0.42, respectively].
Conclusions
The prescription of RAASi or β-blocker at discharge was associated with lower adverse CV event rates in patients on regular HD who were hospitalized for HF. In order to improve long-term prognosis of HF patients on HD, we should consider the prescription of RAASi or β-blocker for them if hemodynamics during HD is affordable.

Abstract
Abstract
Introduction
The recent advances in the treatment for heart failure with reduced ejection fraction (HFrEF) have been remarkable, while no therapy has convincingly improved the prognosis in HF patients with preserved (HFpEF) and mid-range (HFmrEF) ejection fraction. Frequent decompensations of HF lead to progressive deterioration of cardiac and renal function, and quality of life. Hence, prior studies have reported that the mortality of HFrEF patients increases as hospitalization for HF repeats. However, it is still unclear whether this trend applies for HFpEF and HFmrEF patients.
Purpose
We aimed to compare the prognostic impact of re-hospitalization due to HF on cardiovascular death (CVD) among HFrEF, HFmrEF and HFpEF patients.
Methods
This observational study included 1,930 consecutive patients who were hospitalized for worsening of HF and discharged alive. Of them, patients who have never or have not been hospitalized for HF at least last 2 years, were finally analyzed. Patients were consisted of the population with HFrEF (EF<40%, n=421), HFmrEF (EF 40–49%, n=202) and HFpEF (EF>50%, n=291). Patients in each EF-classified population were divide into 2 subgroups based on whether patients were re-hospitalized for HF during the observational period, respectively. The primary endpoint of this study was CVD.
Results
During the observation period, Kaplan-Meier analysis showed that patients who were re-hospitalized for HF had higher event rate of CVD in HFrEF group (Log-rank p=0.008, Figure). Even after adjusting with multivariate covariates including age, sex, EF, brain natriuretic peptide and estimated glomerular filtration rate, re-hospitalization for HF was an independent predictor for CVD in HFrEF group (HR: 1.95, 95% CI: 1.11–2.86, p=0.029). However, in HFmrEF group and HFpEF group, there was no significant difference in the rates of CVD between 2 subgroups divided whether patients were re-hospitalized for HF or not (p=0.91, p=0.34, respectively).
Conclusion
Re-hospitalization for HF affected the CVD rate in HFrEF group, but not in HFmrEF and HFpEF groups. The prevention of re-hospitalization for HF is important particularly in HFrEF patients in order to improve cardiovascular mortality.

Abstract
Abstract
Study question
Does postponement of intracytoplasmic sperm injection (ICSI) timing after spindle visualization for Metaphase I (MI) oocytes improve developmental outcomes of embryos?
Summary answer
Postponement of ICSI timing after spindle visualization for MI oocytes improves blastocyst utility rates.
What is known already
Immature oocytes are generally considered poor developmental outcomes. Meanwhile, the timing of ICSI adjusted by using spindle visualization can improve clinically utilized embryos and live birth rates, but these outcomes remain inferior to those of mature oocytes. In in vitro maturation culture, nuclear maturation is thought to occur before the completion of cytoplasmic maturation, and in immature oocytes, synchronization of nuclear and cytoplasmic maturation may be insufficient for ICSI immediately after spindle visualization.
Study design, size, duration
Data for this retrospective cohort study were obtained 672 oocytes retrieved under mild stimulation cycles using letrozole, in patients aged younger than 39 years between April 2017 and October 2020.Written informed consent was obtained from all patients. This study was approved by the institutional review board.
Participants/materials, setting, methods
As a control group, 464 MetaphaseIIoocytes that underwent ICSI immediately after visualization of the spindle were used. In group A, 103 MI oocytes underwent ICSI immediately after the first polar body release and spindle visualization, and in group B, 105 oocytes underwent ICSI 2–3 hours after spindle visualization. The primary outcomes were fertilization rates, degeneration, cleavage, embryo blastocyst formation, and utility rates. Outcomes were compared among the three groups.
Main results and the role of chance
The baseline fertilization rates of each group (control, A, B) were 82.3% (382/464), 73.8% (76/103), and 83.8% (88/105), respectively. The rate was significantly lower in group A than in the control group (P < 0.05), and also tended to be lower in group A than in group B, although the difference was not significant. There was no significant difference in abnormal fertilization rates, oocyte degeneration rates, cleavage rates, and blastocyst formation rates among the three groups. [control, A, B: abnormal fertilization rate: 4.3% (20/464), 8.7% (9/103), 4.8% (5/105); oocyte degeneration rates: 3.0% (14/464), 1.9% (2/103), 3.8% (4/105); cleavage rates: 95.6% (307/321), 93.8% (61/65), 98.7% (74/75); blastocyst formation rates: 58.6% (177/302), 51.7% (31/60), 55.4% (41/74), respectively]. The blastocyst utility rates of control group and group B were significantly higher than in group A [41.7% (126/302), 45.9% (34/74), 26.7% (16/60), respectively] (P < 0.05). There were no significantly different outcomes between the control group and group B.
Limitations, reasons for caution
The optimal timing of ICSI for MI oocyte cannot be determined by the presence or absence of spindles. In addition, the postponement duration we set was based on reports which reported on final oocyte maturation, and further investigation is needed to establish the optimal ICSI timing for MI oocytes.
Wider implications of the findings: In MI oocytes, postponement of ICSI timing after spindle visualization is essential for synchronization of the nucleus and cytoplasmic maturation.

Abstract
Abstract
Study question
Are one live birth rates (LBRs) similar in minimal stimulation cycle IVF with letrozole only and natural cycle IVF for the first ART cycle?
Summary answer
LBRs after first ART cycle in minimal stimulation cycle IVF with letrozole only are superior to natural cycle IVF.
What is known already
The addition of letrozole to gonadotropins in ovarian stimulation (OS) may reduce the risk of OHSS, but there is no significant difference were reported in ongoing pregnancy rate or number of oocytes retrieved in the letrozole + FSH group compared to the FSH only. No differences were also reported in clinical pregnancy rates or number of mature oocytes in the additional of letrozole in an GnRH antagonist protocol group compared to the GnRH antagonist group. There are no previous study comparing LBRs after first ART cycle in minimal stimulation cycle IVF with letrozole and natural cycle IVF.
Study design, size, duration
Data for this retrospective cohort study were obtained 643 women, 30–39 years of age started their first ART cycle at one private fertility clinic between January 2016- December 2019.
Participants/materials, setting, methods
A total of 643 women were scheduled their first oocyte retrieval cycle. 118 women started with letrozole (LE) and 525 women started natural cycle (NC). The main strategy for OS in our center is minimal stimulation and natural cycle IVF. Patients consulted with gynecologists to determine their treatment plan based on patients’ preference or their menstrual cycle. All pregnancies generated from oocyte retrieval during the first IVF cycle including fresh and frozen-thaw cycles were registered.
Main results and the role of chance
The number of retrieved oocytes and the normal fertilization rates were significantly higher in the LE than NC (4.4 vs 3.4, 77.6% vs 71.1%), p < 0.05 respectively). There was no significant difference in the clinical pregnancy rates (CPRs) per embryo transfer (ET) (fresh cleavage stage ET: 32.9% vs 28.0%, frozen-thaw blastocyst ET: 39.4% vs 44.9% ns). However, the CPRs and LBRs per oocyte retrieval (OR) were significantly higher in the LE group (39.0% vs 28.6, 33.9% vs 21.9%, p < 0.05 respectively). In a subsequent regression analyses, LBRs per OR of LE was significantly higher than NC as well. (adjusted OR = 1.63 (95% CI: 1.02–2.58, p = 0.041).
Limitations, reasons for caution
The strength of the present study was the use of a large cohort of women who underwent minimal stimulation IVF with letrozole only. Although our results are promising, limited by retrospective cohort study. These interpretations prompted the need for a perspective cohort study to evaluate the efficacy of letrozole.
Wider implications of the findings: When comparing minimal stimulation IVF with letrozole only and natural cycle IVF, we found significantly higher LBRs per OR in minimal stimulation IVF with letrozole only, despite similar CPRs per ET.

Abstract
e12547 Background: Higher body mass index (BMI) has been associated with an increased risk of developing hormone receptor (HR)-positive breast cancer (BC) in postmenopausal women, but its relationship with prognosis in patients with HR-positive BC remains unclear. In particular, there is limited data on BMI and prognosis in Asian patients with BC, whose BMI distribution differs from that of Westerners. Methods: We retrospectively reviewed data from Japanese women who underwent curative surgery for clinical stage I-III HR-positive BC in our institution between January 2007 and December 2017. The patients were classified into five groups based on BMI: underweight (UW), BMI < 18.5 kg/m2; normal weight (NW), 18.5 to 24.9 kg/m2; obese 1 degree (OB1), 25.0 to 29.9 kg/m2; obese 2 degree (OB2), 30.0 to 34.9 kg/m2; obese 3 degree (OB3), ≥ 35 kg/m2. We compared the clinicopathological features between patients with OB1-3 and those with UW and NW. The prognostic analysis of breast cancer-specific survival (BCSS) and overall survival (OS) was performed using the log-rank test and Cox proportional hazards model between the two groups. Subgroup analysis of BCSS and OS was performed in premenopausal and postmenopausal patients. Results: Overall, 6,421 patients were included in the study. The median follow-up duration was 5.9 years (range, 0.2-12.9). The number of patients with UW, NW, OB1, OB2, or OB3 was 599 (9%), 4477 (70%), 1085 (17%), 224 (3%), and 36 (1%), respectively. Of these, 3380 (53%) were premenopausal and 2968 (46%) were postmenopausal. Patients with OB1-3 had a significantly higher stage of BC, a higher number of lymph node metastases, and were associated with higher Ki67 index and nuclear grade compared to those with UW and NW. A total of 521 all-cause and 307 breast cancer-specific deaths as well as 824 recurrences were observed. Both BCSS and OS in patients with OB1-3 were significantly worse than those in the UW and NW patients (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.14-2.42; HR, 1.64; 95%CI, 1.25-2.18, respectively) by univariate analysis. In addition, the Kaplan-Meier curve for each BMI group showed that the prognosis of BCSS and OS was gradually worse in the order of NW, OB1, OB2, and OB3. Subgroup analysis revealed that BCSS and OS were significantly worse in patients with OB1-3 than in those with UW and NW for premenopausal patients (HR, 2.37; 95%CI, 1.40-4.02; HR, 1.91; 95%CI, 1.17-3.11, respectively), but not for postmenopausal patients (HR, 1.26; 95%CI, 0.74-2.16; HR, 1.29; 95%CI, 0.92-1.82, respectively). Multivariate analysis showed that tumor stage and nuclear grade were independent prognostic factors, but OB1-3 was not. Conclusions: Obesity was associated with a worse prognosis as it correlated with advanced stage and high nuclear grade in Japanese patients with HR-positive BC, especially in premenopausal patients.

[PMID: 33984681 PMCID: PMC8134659 DOI: 10.1016/j.esmoop.2021.100115] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 03/14/2021] [Accepted: 03/19/2021] [Indexed: 11/25/2022] Open
Abstract
Background FLAURA, the prospective trial of osimertinib as a first-line therapy compared with first-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), did not show superior survival benefit for osimertinib in either the subgroup of Asians or the subgroup with the L858R mutation. In addition, the superiority of osimertinib compared with second-generation EGFR-TKI is thus far unclear. Patients and methods We reviewed the clinical data of all consecutive patients who were treated with osimertinib or afatinib as first-line therapy between May 2016 and October 2019 from 15 institutions in Japan. We defined the groups based on first-line EGFR-TKI as the afatinib group and the osimertinib group. Outcomes included time to discontinuation of any EGFR-TKI (TD-TKI), overall survival (OS), and time to treatment failure, with propensity score analysis carried out as an exploratory analysis in the survival and subgroup analyses. Results A total of 554 patients were enrolled. Data on 326 patients in the osimertinib group, and 224 patients in the afatinib group were analyzed. TD-TKI adjusted by propensity score in the afatinib and osimertinib groups was 18.6 months (95% confidence interval 15.8 to 22.0) and 20.5 months (95% confidence interval 13.8 to not reached), respectively, without significant difference (P = 0.204). OS adjusted by propensity score favored the afatinib group with a significant difference (P = 0.018). Subgroup analysis with propensity score showed that patients with L858R and without brain metastasis had superior survival benefit with afatinib compared with osimertinib (P < 0.001). Conclusions TD-TKI in the afatinib group was not significantly prolonged compared with the osimertinib group in the practical data. In the exploratory analysis of patients with L858R-mutated non-small-cell lung cancer without brain metastasis, afatinib showed more benefit in OS over osimertinib. The large-scale practical data of 550 patients who were treated with osimertinib or afatinib as first-line therapy were analyzed. The superiority of osimertinib compared with afatinib could not be demonstrated in all populations. Osimertinib therapy showed effectiveness in patients with brain metastasis. Afatinib therapy showed potential benefit in patients with L858R mutation and without brain metastasis.

Abstract
Abstract
Background
The early transmitral flow velocity (E) divided by the early diastolic velocity of the mitral valve annulus (e') is referred to as the “E/e' ratio,” is useful even for ST elevation acute myocardial infarction (STEMI). However, the role of late diastolic velocity (a') which reveals the atrial function for STEMI is still unclear.
Objectives
We evaluated the clinical usefulness of tissue Doppler including atrial function for a first-time STEMI by long time follow up. Furthermore, we evaluated the meaning of each parameters by performing immediately after PCI or 2 weeks later.
Methods
We treated consecutive 571 first-time STEMI patients by immediate PCI within 12 hours after onset, and we examined 270 patients at immediately after PCI (GroupA, 65 years, 250 male) and 301 patients at 2 weeks after onset (GroupB, 64 years, 243 male). We examined trans mitral flow and TDI, then defined E/e' as LV filling pressure and A/a' as left atrial function. We followed them for a long time (>5 years). The primary end point (PE) was cardiac death or re-admission for heart failure (HF).
Results
We followed the patients in Group A for 10 years, Group B for 5 years. PE occurred in 64 patients in GroupA during 10 years, and 45 patients in GroupB during 5 years. We analyzed the univariate and multivariate Cox hazard analyses and we compared e' and a', E/e' and A/a' (Table). In GroupA, a' and A/a' were the independent predictors, on the other hand neither a' nor A/a' were the predictors in GroupB. E/e' was an independent predictor both in GroupA and B.
Conclusion
TDI parameters have different meanings by the timing of echocardiography after onset of a first-time STEMI. These results demonstrated that atrial dysfunction immediately after onset of STEMI suggests the poor prognosis after STEMI.

Abstract
Abstract
Background
In the last two decades, catheter ablation (CA) for atrial fibrillation (AF) including pulmonary vein isolation (PVI) has been developed as a standard and effective treatment for atrial fibrillation (AF). In patients with chronic heart failure with reduced left ventricular ejection fraction (LVEF) (HFrEF), PVI CA for AF dramatically improves LVEF, resulting in better clinical prognoses. On the contrary, there still has been no data that PVI CA for AF improves the prognosis in heart failure patients with preserved LVEF (HFpEF).
Purpose
The aim of this study was to evaluate the prognostic impact of PVI CA for AF after the hospitalization due to decompensation of heart failureHF, focusing on LVEF.
Methods
From the database including 1,793 consecutive patients who were hospitalized due to congestive HF, we ultimately analyzed 624 AF patients who were discharged alive. They were assigned into two groups due that PVI CA for AF procedure done after the index hospitalization for HF; the PVI CA group (n=62) and Non-PVI CA group (n=562). For the two groups, we performed propensity-score (PS) matching using variables as follows: age, sex, LVEF, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) and estimated glomerular filtration rate (eGFR) at discharge. Further analysis was performed separately in HFrEF (LVEF <50%) and HFpEF (LVEF >50%). The primary endpoint of this study was death from any cause.
Results
In unmatched patients, Kaplan-Meier analysis showed that patients in the PVI CA group had a significantly lower all-cause mortality than those in the Non-PVI CA group during 678 median follow-up period (Log-rank test: P=0.003, Figure A). In 96 PS-matched patients, patients in the PVI CA group still had lower mortality rate than those in the Non-PVI CA group (hazard ratio 0.28, 95% confidence interval 0.09–0.86, p=0.018, Figure B). When the whole study population was classified into HFrEF and HFpEF, HFrEF patients who received PVI showed a significantly lower mortality than those who did not (p=0.007); whereas, in HFpEF patients, PVI CA for AF did not make statistical difference in all-cause mortality (p=0.061).
Conclusions
In this observational study, PVI CA for AF may improve the mortality in HF patients with reduced LVEF. However, the prognostic impact of PVI CA for AF was not observed in HF patients with preserved LVEF.

Abstract
Abstract
Introduction
Deferral of percutaneous coronary intervention (PCI) of a functionally insignificant stenosis is associated with favorable long-term prognoses. However, previous reports revealed that patients with fractional flow reserve (FFR) 0.81–0.85 had higher cardiovascular adverse event rates than those with FFR >0.85. Numbers of large clinical trials established the lower, the better strategy for low-density lipoprotein cholesterol (LDL-C) management for patients after PCI. However, in the real clinical practice, the achievement rate of target LDL-C is often insufficient in patients with atherosclerotic risk factors who were functionally deferred PCI.
Purpose
We aimed to examine optimal LDL-C management for patients with intermediate coronary stenosis deferred PCI by FFR measurement.
Methods
This observational study included 293 consecutive patients with coronary stenosis deferred PCI due to greater FFR than 0.80. We separately analyzed 90 patients with 0.81–0.85 of FFR and 203 patients with >0.85. Patients in each group were further classified into 2 groups based on LDL-C level at one year after FFR measurement; the Lower LDL-C group (<100 mg/dL) and the Higher LDL-C group (>100 mg/dL). The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE) including death, non-fatal myocardial infarction, ischemic stroke, heart failure hospitalization and unplanned revascularization.
Results
Patients with FFR 0.81–0.85 had a significantly higher MACCE rate than those with FFR >0.85 (hazard ratio (HR): 1.77, 95% confidence interval (CI): 1.02–3.07, p=0.043). In patients with FFR 0.81–0.85, the Lower LDL-C group (n-=53) had a significantly lower rate of the primary endpoint than the Higher LDL-C group (HR: 0.41, 95% CI: 0.18–0.97, Log-rank p=0.036, Figure A). Whereas, there was no significant difference in the event rate between 2 groups in patients with FFR >0.85 (Log-rank p=0.42, Figure B).
Conclusion
Uncontrolled LDL-C level was associated with higher MACCE rate in patients who were deferred PCI due to FFR 0.81–0.85. These results suggested that even in patients who were deferred PCI, those with coronary artery stenosis of lower FFR value should receive strict LDL-C lowering therapy with close monitoring.
