RESUMO

OBJECTIVES: People living with HIV (PLWHIV) are susceptible to opportunistic infections including herpes zoster (HZ) and postherpetic neuralgia (PHN). The recombinant zoster vaccine (RZV) (Shingrix) is available in some countries. However, the cost-effectiveness for PLWHIV remains unknown. This study aimed to analyze the cost-effectiveness of RZV for PLWHIV ≥50 years old. METHODS: A Markov model was developed to compare the cost-effectiveness of the 2-dose RZV immunization program with no RZV immunization for PLWHIV aged ≥50 years. We built the model with a yearly cycle over a 30-year period and 6 health conditions: HZ free, HZ, PHN, HZ/PHN recovery, HZ recurrence, and death. The parameters in the model were based on previous studies and a nationwide administrative claims database in Japan. The incremental cost-effectiveness ratio (ICER), expressed as Japanese yen (JPY) per the quality-adjusted life-years (QALYs), was estimated from a societal perspective. We conducted a one-way deterministic sensitivity analysis, probabilistic sensitivity analysis with Monte Carlo simulations of 10 000 samples, and scenario analyses. RESULTS: The ICER of the 2-dose RZV immunization program over no RZV immunization was 78 777 774 JPY (approximately 600 000 US dollars)/QALY. The one-way deterministic sensitivity analysis showed that HZ-related utility was the most significant for ICER. All estimates in the probabilistic sensitivity analysis were located above the willingness-to-pay threshold of 5 million JPY/QALY. CONCLUSIONS: Our study revealed that no RZV immunization was more cost-effective than the 2-dose RZV immunization program for PLWHIV aged ≥50 years. This may be useful in evidence-based policy making.

RESUMO

BACKGROUND: Characteristics, practice patterns, and clinical outcomes of secondary spontaneous pneumothorax (SSP) with heritable connective tissue disorders (Marfan, Ehlers-Danlos, and Birt-Hogg-Dubé syndromes) are unclear. METHODS: A nationwide Japanese inpatient database that included data of 524 patients with SSP (884 hospitalizations) and 137,821 with primary spontaneous pneumothorax between July 2010 and March 2020 was used in this study. Hospitalization for SSP (n = 884) was categorized into surgical (n = 459) and nonsurgical (n = 425) groups, and the patient characteristics, treatment, and outcomes were compared between the groups. Multivariable analyses were performed to evaluate risk factors for pneumothorax recurrence. We also compared the characteristics of patients with different underlying heritable connective tissue disorders. RESULTS: Compared with the nonsurgical group, the surgical group had less frequent readmission for pneumothorax (26% vs 44%; hazard ratio, 0.47; 95% CI, 0.38-0.58). Young patients (2.46; 1.83-3.32) or those with Birt-Hogg-Dubé syndrome (2.53; 1.77-3.63) had a high risk of recurrence. Pneumothorax occurred frequently in teenagers with Marfan syndrome, in those aged 20 to 39 years with Ehlers-Danlos syndrome, and in those aged ≥40 years with Birt-Hogg-Dubé syndrome. CONCLUSIONS: Detailed information on the characteristics and clinical course of SSP in heritable connective tissue disorders will aid in the clinical decision-making process.

RESUMO

BACKGROUND: It is unclear whether the sequential administration of programmed death (PD)-1/programmed death-ligand 1 (PD-L1) inhibitors and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) is associated with the development of severe interstitial pneumonitis (IP). PATIENTS AND METHODS: We identified 69,107 eligible patients with non-small cell lung cancer (NSCLC) from a Japanese national inpatient database, who initiated EGFR-TKI therapy. The study population was divided into the PD-1/PD-L1 inhibitor and non-prior PD-1/PD-L1 groups based on PD-1/PD-L1 administration before EGFR-TKI therapy. We conducted 1:4 matched-pair cohort analyses (n = 9,725) to compare the incidence of IP and in-hospital mortality within 90 days of administration of EGFR-TKI between the two groups after adjusting for the clinical background. Furthermore, we performed subgroup analyses categorized according to the duration of prior PD-1/PD-L1 inhibitor use. RESULTS: IP occurred in 4.4% of patients in the matched-pair cohort. PD-1/PD-L1 inhibitor-use before EGFR-TKI therapy was significantly associated with IP (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.34-2.38) and in-hospital mortality (OR, 2.10; 95% CI, 1.72-2.55). Prior PD-1/PD-L1 inhibitor use in an interval of <6 months before EGFR-TKI administration was associated with a higher risk of IP than EGFR-TKI administration without prior PD-1/PD-L1 inhibitor. In-hospital mortality was higher in patients with prior PD-1/PD-L1 inhibitor use than that in those without prior PD-1/PD-L1 inhibitor use, irrespective of the treatment duration. CONCLUSION: Sequential use of PD-1/PD-L1 inhibitors and EGFR-TKIs in patients with non-small cell lung cancer was significantly associated with IP compared to EGFR-TKIs without prior PD-1/PD-L1 inhibitor administration.

RESUMO

In Japan, a public long-term care insurance system was launched in 2000. Residents can receive long-term care according to their care needs, as determined by a nationally standardized certification system. The present report describes the details of the long-term care services covered by public insurance. The Long-Term Care Insurance Act categorizes services into three major types: in-home, nursing-home, and community-based long-term care services. In-home care services include visiting, commuting, short-stay, and other services. Welfare, health, and medical facilities provide nursing-home care services for the elderly. Community-based care services were categorized into visiting, commuting, nursing-home, and composite services.

RESUMO

This is a prognostic report by the Japanese Breast Cancer Society on breast cancer extracted from the National Clinical Database-Breast Cancer Registry of Japan. Here, we present a summary of 457,878 breast cancer cases registered between 2004 and 2016. The median follow-up duration was 5.6 years. The median age at the start of treatment was 59 years (5-95%: 38-82 years) and increased from 57 years between 2004 and 2008 to 60 years between 2013 and 2016. The proportion of patients with Stage 0-II disease increased from 74.5% to 78.3%. The number of cases with estrogen and progesterone receptor positivity increased from 74.8% to 77.9% and 60.5% to 68.1%, respectively. Regarding (neo-)adjuvant chemotherapy, the taxane (T) or taxane-cyclophosphamide (C) regimen increased by 2.4% to 8.2%, but the (fluorouracil (F)) adriamycin (A)-C-T/(F) epirubicin (E)C-T and (F)AC/(F)EC regimens decreased by 18.6% to 15.2% and 13.5% to 5.0%, respectively. Regarding (neo-)adjuvant anti-human epidermal growth factor-2 (HER2)-targeted therapy, the use of trastuzumab increased from 4.6% to 10.5%. The rate of sentinel lymph node biopsy increased from 37.1% to 60.7%, while that of axillary dissection decreased from 54.5% to 22.6%. Improvements in disease-free and overall survival were observed in patients with HER2-positive breast cancer, but there was no apparent trend in patients with hormone receptor-positive, HER2-negative, or triple-negative breast cancers.

RESUMO

Introduction: Stroke is a major cause of disability and mortality worldwide and requires long-term care, including rehabilitation. This study aims to elucidate the association between care-need levels after discharge and long-term outcomes in patients with stroke. Methods: We used a Japanese administrative database that covers both medical and long-term care insurance systems to retrospectively identify 7491 patients who underwent acute-phase in-hospital rehabilitation for stroke between June 2014 and February 2019. We investigated the association between nationally standardized care-need levels (support levels 1-2 and care-need levels 1-3) 6 months after discharge and long-term outcomes. Using the Fine-Gray model, we conducted multivariable survival analysis with adjustment for patient backgrounds and treatment courses to estimate hazard ratios (HR) for mortality and the incidence of being bedridden. Results: The median age was 82 (interquartile range [IQR], 76-87) years, 5418 patients (72%) had cerebral infarction, and 4009 patients (54%) had partial dependence after discharge. During a median follow-up of 580 (IQR, 189-925) days, 1668 patients (22%) became bedridden, and 2174 patients (29%) died. Compared with patients with support level 1, those with higher care-need levels showed significantly higher proportions of being bedridden-the subdistribution HR [95% confidence interval] were 1.52 [1.10-2.12], 2.85 [2.09-3.88], and 3.79 [2.79-5.15] in those with care-need levels 1, 2, and 3, respectively. Higher care-need levels were also significantly associated with higher mortality. Conclusions: This large-scale observational study demonstrated that a higher level of care-need after discharge was significantly associated with poorer functional outcomes and higher mortality.

RESUMO

The Japanese Breast Cancer Society initiated the breast cancer registry in 1975, which transitioned to the National Clinical Database-Breast Cancer Registry in 2012. This annual report presents data from 2020 and analyzes the ten-year mortality rates for those aged 65 and older. We analyzed data from 93,784 breast cancer (BC) cases registered in 2020 and assessed 10-year mortality rates for 36,279 elderly patients diagnosed between 2008 and 2012. In 2020, 99.4% of BC cases were females with a median age of 61. Most (65%) were diagnosed at early stages (Stage 0 or I). Breast-conserving surgery rates varied with stages: 58.5% at cStage I, 30.8% at cStage II, and 13.1% at cStage III. Sentinel lymph node biopsy was done in 73.6% of cases, followed by radiotherapy in 70% of those post-conserving surgery and chemotherapy in 21.1% post-surgery. Pathology showed that 63.4% had tumors under 2.0 cm, 11.7% had pTis tumors, and 77.3% had no axillary lymph node metastasis. ER positivity was seen in 75.1%, HER2 in 14.3%, and 30% had a Ki67 positivity rate above 30%. Across all stages and subtypes, there was a trend where the 10-year mortality rates increased for individuals older than 65 years. In Stage I, many deaths were not directly linked to BC and, for those with HER2-type and triple-negative BC, breast cancer-related deaths increased with age. Within Stage II, patients older than 70 years with luminal-type BC often experienced deaths not directly linked to BC, whereas patients below 80 years with HER2-type and triple-negative BC, likely had breast cancer-related deaths. In Stage III, breast cancer-related deaths were more common, particularly in HER2 and triple-negative BC. Our prognostic analysis underscores distinct mortality patterns by stage, subtype, and age in elderly BC patients. It highlights the importance of personalized treatment strategies, considering subtype-specific aggressiveness, age-related factors, and comorbidities.

RESUMO

BACKGROUND: Although neonatal disseminated intravascular coagulation (DIC) is associated with high mortality and severe complications, few studies have reported its clinical course. We aimed to describe the characteristics, treatments, and outcomes of neonatal DIC by using a national inpatient database. METHODS: Using the Japanese Diagnosis Procedure Combination database, we identified 5533 patients with neonatal DIC who were admitted to neonatal intensive care units between July 2010 and March 2020. We categorized the patients into those with asphyxia (n = 2911) and those without asphyxia (n = 2622). We investigated the patient characteristics, treatments, and outcomes. We further categorized neonates with asphyxia according to its severity. RESULTS: The gestational age of neonates with asphyxia was significantly lower than that of neonates without asphyxia (P < 0.001). Antithrombin was most commonly used for DIC (40%). Neonates with asphyxia were more likely to receive antithrombin (43% vs. 38%; P < 0.001), recombinant human soluble thrombomodulin (28% vs. 20%; P < 0.001), and fresh frozen plasma transfusion (68% vs. 51%; P < 0.001) than those without asphyxia. Neonates with asphyxia had higher in-hospital mortality (17% vs. 10%; P < 0.001), severe bleeding (11% vs. 6.8%; P < 0.001), and hospitalization costs than those without asphyxia. Additionally, neonates with severe asphyxia were more likely to receive several DIC therapies (such as recombinant human soluble thrombomodulin [30% vs. 24%]) and had higher in-hospital mortality (19% vs. 11%) and hospitalization costs than those with mild asphyxia. CONCLUSIONS: In this large retrospective study of neonatal DIC, patients with asphyxia received several treatments and demonstrated unfavorable outcomes when compared to those without asphyxia.

RESUMO

Objective Recommendations on the timing of Legionella urinary antigen tests for community-acquired pneumonia patients differ among guidelines in Japan, the United States, and European nations. We therefore evaluated the association between the timing of urinary antigen tests and in-hospital mortality in patients with Legionella pneumonia. Methods We conducted a retrospective cohort study using the Diagnosis Procedure Combination database, a nationwide database of acute care inpatients in Japan. Patients who underwent Legionella urinary antigen tests on the day of admission formed the tested group. Patients who were tested on day 2 of admission or later or were unexamined formed the control group. We performed a propensity score matching analysis to compare in-hospital mortality, length of hospital stay and duration of antibiotics use between the two groups. Results Of the 9,254 eligible patients, 6,933 were included in the tested group. One-to-one propensity score matching generated 1,945 pairs. The tested group had a significantly lower 30-day in-hospital mortality than the control group (5.7 vs. 7.7%; odds ratio, 0.72; 95% confidence intervals, 0.55-0.95; p=0.020). The tested group also showed a significantly shorter length of stay and duration of antibiotics use than the control group. Conclusion Urine antigen testing upon admission was associated with better outcomes in patients with Legionella pneumonia. Urine antigen tests upon admission may be recommended for all patients with severe community-acquired pneumonia.

RESUMO

OBJECTIVE: To describe characteristics, treatments and clinical outcomes of patients with trisomy 18 and oesophageal atresia, using a nationwide database in Japan. DESIGN: Descriptive study using a retrospective cohort. SETTING: A nationwide inpatient database including 90% of hospitals with neonatal intensive care units in Japan. PATIENTS: Patients hospitalised within a day after birth for both oesophageal atresia and trisomy 18 between July 2010 and March 2020. INTERVENTIONS: Radical surgery for oesophageal atresia. MAIN OUTCOME MEASURES: Characteristics, treatment course and outcomes. RESULTS: Among 271 patients with both oesophageal atresia and trisomy 18, 70 patients underwent radical surgery for oesophageal atresia. Patients who underwent radical surgery were less likely to have severe cardiac anomalies (17% vs 32%; p=0.020), but more likely to undergo cardiac surgery (21% vs 9.5%; p=0.012) than those who did not. The overall in-hospital mortality was lower (54% vs 79%; p<0.001) and the median age at death was higher (210 days vs 39 days; p<0.001) in patients who underwent radical surgery than the others. Postoperative mortality within 30 days after radical surgery was 5.7%. Patients who underwent radical surgery were likely to be discharged to home (50% vs 18%; p<0.001), whereas the age at home discharge (median 314 days vs 216 days; p=0.19) and the requirement for each home treatment did not differ significantly by radical surgery. CONCLUSION: This study provides information that will aid the clinical decision-making process for patients with oesophageal atresia and trisomy 18. Radical surgery may be a safe and feasible treatment option.

RESUMO

BACKGROUND: Although autologous reconstruction following breast cancer surgery is common, little is known about the association between preoperative body mass index (BMI) and short-term surgical outcomes. This study investigated the association between BMI and short-term surgical outcomes in autologous breast reconstruction using a nationwide Japanese inpatient database. METHODS: We retrospectively identified female patients with breast cancer who underwent breast reconstruction using a pedicled flap or free flap from July 2010 to March 2020. Multivariable regression analyses and restricted cubic spline analyses were conducted to investigate the associations between BMI and short-term outcomes with adjustment for demographic and clinical backgrounds. RESULTS: Of the 13,734 eligible patients, 7.1% and 22.2% had a BMI of < 18.5 kg/m2 and > 25 kg/m2, respectively. Compared with BMI of 18.5-21.9 kg/m2, overweight (25.0-29.9 kg/m2) and obese (≥ 30.0 kg/m2) were significantly associated with higher occurrences of takebacks (odds ratio, 1.74 [95% confidence interval, 1.28-2.38] and 2.89 [1.88-4.43], respectively) and overall complications (1.37 [1.20-1.57] and 1.77 [1.42-2.20], respectively). In the restricted cubic spline analyses, BMI showed J-shaped associations with takebacks, overall complications, local complications, and wound dehiscence. BMI also demonstrated linear associations with postoperative surgical site infection, duration of anesthesia, duration of drainage, length of stay, and hospitalization costs. CONCLUSION: In autologous breast reconstruction following breast cancer surgery, a higher BMI was associated with takebacks, morbidity, a longer hospital stay, and higher total costs, whereas a lower BMI was associated with fewer surgical site infections, a shorter hospital stay, and lower total costs.

RESUMO

BACKGROUND/OBJECTIVES: This study aimed to compare the cost-effectiveness of prophylactic laser peripheral iridotomy (LPI) with that of observation for primary angle-closure suspect (PACS) in Japan. SUBJECTS/METHODS: A Markov model was developed to compare the costs and utilities of prophylactic LPI with those of observation of 40-year-old patients with PACS. In the model with a yearly cycle over a 20-year time horizon, the disease was postulated to irreversibly progress from PACS to primary angle closure, followed by primary angle-closure glaucoma, unilateral blindness, and bilateral blindness. The parameters were estimated mainly based on a recent randomised controlled trial and analyses of Japanese claims data. The incremental cost-effectiveness ratio was estimated from the healthcare payer's perspective and evaluated at the willingness-to-pay 5 million Japanese Yen per quality-adjusted life-year. The observation period and the age at entry into the cohort was changed to account for a variety of clinical courses in sensitivity analyses. We conducted one-way deterministic sensitivity analysis and probabilistic sensitivity analysis with Monte Carlo simulations with 10 000 iterations. RESULTS: The incremental cost-effectiveness ratio of LPI was 2,287,662 Japanese Yen (14,298 pounds sterling) per quality-adjusted life-year, which was below the willingness-to-pay threshold. The ratios were approximately 4 and 8 million in the 15-year and 10-year time horizons, respectively. Increasing the age at entry had little influence on the incremental cost-effectiveness ratio. The deterministic and probabilistic sensitivity analyses indicated that the results were robust. CONCLUSIONS: Our results indicate that prophylactic LPI for middle-aged patients with PACS is cost-effective in Japan.

RESUMO

AIM: Kakkonto, a Japanese herbal kampo medicine, is empirically prescribed to improve milk stasis and ameliorate breast inflammation in patients with noninfectious mastitis. We investigated whether early use of kakkonto is associated with a reduction in antibiotic use and surgical drainage in patients with noninfectious mastitis. METHODS: We identified 34 074 patients with an initial diagnosis of noninfectious mastitis within 1 year of childbirth between April 2012 and December 2022 using the nationwide administrative JMDC Claims Database. Patients were divided into the kakkonto (n = 9593) and control (n = 9648) groups if they received and did not receive kakkonto on the day of the initial diagnosis of noninfectious mastitis, respectively. Antibiotic administration and surgical drainage within 30 days after the initial diagnosis of noninfectious mastitis in the two groups were compared using propensity score-stabilized inverse probability of treatment weighting analysis. RESULTS: The frequency of antibiotic administration within 30 days after the initial diagnosis of noninfectious mastitis was significantly lower in the kakkonto group than in the control group (10% vs. 12%; odds ratio, 0.88 [95% confidence interval, 0.80-0.96]). The frequency of antibiotic administration during 1-3 and 4-7 days after the initial diagnosis were also significantly lower in the kakkonto group than in the control group. The frequency of surgical drainage did not differ significantly between the two groups. CONCLUSIONS: Kakkonto was associated with reduced administration of antibiotics for noninfectious mastitis, making it a potential treatment option for relieving breast inflammation and promoting antimicrobial stewardship.

RESUMO

Objective The effect of Rikkunshito, a Japanese herbal Kampo medicine, on chemotherapy-induced nausea and vomiting (CINV) has been evaluated in several small prospective studies, with mixed results. We retrospectively evaluated the antiemetic effects of Rikkunshito in patients undergoing cisplatin-based chemotherapy using a large-scale database in Japan. Methods The Diagnosis Procedure Combination inpatient database from July 2010 to March 2019 was used to compare adult patients with malignant tumors who had received Rikkunshito on or before the day of cisplatin administration (Rikkunshito group) and those who had not (control group). Antiemetics on days 2 and 3 and days 4 and beyond following cisplatin administration were used as surrogate outcomes for CINV. Patient backgrounds were adjusted using the stabilized inverse probability of treatment weighting, and outcomes were compared using univariable regression models. Results We identified 669 and 123,378 patients in the Rikkunshito and control groups, respectively. There were significantly fewer patients using intravenous 5-HT3-receptor antagonists in the Rikkunshito group (odds ratio, 0.38; 95% confidence interval, 0.16-0.87; p=0.023) on days 2 and 3 of cisplatin-based chemotherapy. Conclusion The reduced use of antiemetics on day 2 and beyond of cisplatin administration suggested a beneficial effect of Rikkunshito in palliating the symptoms of CINV.

RESUMO

This is an annual report by the Japanese Breast Cancer Society regarding the clinical data on breast cancer extracted from the National Clinical Database-Breast Cancer Registry (NCD-BCR) of Japan. Here, we present an updated summary of 98,300 breast cancer cases registered in 2019. The median age at cancer diagnosis was 61 years (interquartile range 49-72 years), and 30.6% of the breast cancer patients were premenopausal. Of the 93,840 patients without distant metastases, 14,118 (15.0%) and 42,047 (44.8%) were diagnosed with stage 0 and I disease, respectively. Breast-conserving surgery was performed in 42,080 (44.8%) patients. Regarding axillary procedures, 62,677 (66.8%) and 7371 (7.9%) patients underwent sentinel node biopsy and axillary node dissection after biopsy, respectively. Whole breast irradiation was administered to 29,795 (70.8%) of the 42,080 patients undergoing breast-conserving surgery. Chest wall irradiation was administered to 5524 (11.1%) of the 49,637 patients who underwent mastectomy. Of the 6912 clinically lymph node-negative patients who received preoperative therapy, 5250 (76.0%) and 427 (6.2%) underwent sentinel node biopsy and axillary node dissection after biopsy, respectively; however, 602 (8.7%) patients initially underwent axillary node dissection without biopsy.

RESUMO

OBJECTIVE: To assess the effect of antimicrobial prophylaxis with ampicillin-sulbactam (ABPC/SBT) compared with cefazolin (CEZ) on the short-term outcomes after esophagectomy. BACKGROUND: CEZ is widely used for antimicrobial prophylaxis in esophagectomy without procedure-specific evidence, whereas ABPC/SBT is preferred in some hospitals to target both aerobic and anaerobic oral bacteria. METHODS: Data of patients who underwent esophagectomy for cancer between July 2010 and March 2019 were extracted from a nationwide Japanese inpatient database. Overlap propensity score weighting was conducted to compare the short-term outcomes [including surgical site infection (SSI), anastomotic leakage, and respiratory failure] between antimicrobial prophylaxis with CEZ and ABPC/SBT after adjusting for potential confounders. Sensitivity analyses were also performed using propensity score matching and instrumental variable analyses. RESULTS: Among 17,772 eligible patients, 16,077 (90.5%) and 1695 (9.5%) patients were administered CEZ and ABPC/SBT, respectively. SSI, anastomotic leakage, and respiratory failure occurred in 2971 (16.7%), 2604 (14.7%), and 2754 patients (15.5%), respectively. After overlap weighting, ABPC/SBT was significantly associated with a reduction in SSI [odds ratio 0.51 (95% CI: 0.43-0.60)], anastomotic leakage [0.51 (0.43-0.61)], and respiratory failure [0.66 (0.57-0.77)]. ABPC/SBT was also associated with reduced respiratory complications, postoperative length of stay, and total hospitalization costs. The proportion of Clostridioides difficile colitis and noninfectious complications did not differ between the groups. Propensity score matching and instrumental variable analyses demonstrated equivalent results. CONCLUSIONS: The administration of ABPC/SBT as antimicrobial prophylaxis for esophagectomy was associated with better short-term postoperative outcomes compared with CEZ.

RESUMO

INTRODUCTION: Milrinone is administered after patent ductus arteriosus (PDA) ligation to prevent and treat postoperative hemodynamic instability (i.e., postligation cardiac syndrome). We aimed to explore the effectiveness of milrinone on in-hospital outcomes in infants who underwent PDA ligation using a nationwide inpatient database in Japan. METHODS: Using the Japanese Diagnosis Procedure Combination database, we identified patients who received milrinone after PDA ligation (n = 428) in neonatal intensive care units between July 2010 and March 2021 and those who did not (n = 3,392). We conducted a 1:4 propensity score-matched analysis with adjustment for background characteristics (e.g., gestational age, birth weight, comorbidities, preoperative treatments, and hospital background) to compare morbidities (bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and retinopathy of prematurity), mortality, total hospitalization costs, and other outcomes. For sensitivity analysis, we performed an overlap propensity score-weighted analysis. RESULTS: In-hospital morbidity, bronchopulmonary dysplasia, intraventricular hemorrhage, and necrotizing enterocolitis occurred in 58%, 48%, 9.5%, and 7.1% of patients, respectively; the in-hospital mortality was 5.4%. After 1:4 propensity score matching, no significant difference was observed regarding mortality (7.1 vs. 5.7%), in-hospital morbidity (55 vs. 50%), bronchopulmonary dysplasia (44 vs. 41%), intraventricular hemorrhage (7.8 vs. 9.1%), necrotizing enterocolitis (8.5 vs. 8.9%), retinopathy of prematurity (21 vs. 22%), or total hospitalization costs (median: approximately 86,000 vs. 82,000 US dollars) between milrinone users (n = 425) and nonusers (n = 1,698). Sensitivity analyses yielded consistent results. CONCLUSIONS: Milrinone use after PDA ligation was not associated with improved in-hospital outcomes, such as mortality and morbidity.

RESUMO

Background: The guidelines for the requirement of Legionella urinary antigen tests on admission for patients hospitalized with community-acquired pneumonia differ in Japan, the United States, and Europe. We aimed to evaluate the association between the timing of Legionella urinary antigen testing and inhospital mortality in patients with atypical pneumonia. Methods: We identified 654,708 patients with atypical pneumonia from July 2010 to March 2021 using the Japanese national inpatient database. The patients were divided into groups that underwent Legionella urinary antigen tests on the day of admission (test group, n = 229,649) and those that underwent testing after the day of admission or were untested (control group, n = 425,059). A propensity score-stabilized inverse probability of treatment weighting analysis was performed to compare inhospital mortality, length of hospital stay, and total hospitalization costs between the two groups. Odds ratios (ORs) or differences and their 95% confidence intervals (CIs) were calculated using generalized linear models. Results: The tested group had a significantly lower 30-day inhospital mortality than that of the control group (7.7% vs. 9.0%; OR: 0.83 [95% CIs, 0.81-0.86]). The tested group also had a significantly shorter length of stay (difference, -2.3 [-2.6 to - 2.0] days and total hospitalization costs (-396 [-508 to - 285] US dollars) than that of the control group. Conclusions: Legionella urinary antigen testing upon admission is associated with better outcomes in patients with atypical pneumonia. Legionella urinary antigen testing performed on the day of admission is recommended for hospitalized patients with atypical pneumonia.

RESUMO

OBJECTIVES: To determine the associated thromboembolism risk with adding immune checkpoint inhibitors (ICI) to platinum combination chemotherapy compared with platinum combination chemotherapy alone in patients with advanced non-small cell lung cancer. MATERIALS AND METHODS: This study identified 75,807 patients with advanced non-small cell lung cancer from the Japanese Diagnosis Procedure Combination database who started platinum combination chemotherapy between July 2010 and March 2021. The incidence of venous thromboembolism (VTE), arterial thromboembolism (ATE), and all-cause mortality within 6 months after commencing platinum combination chemotherapy was compared between patients receiving chemotherapy with ICI (ICI group, n = 7,177) and without ICI (non-ICI group, n = 37,903). Survival time analysis was performed using the overlap weighting method with propensity scores to adjust for background factors. The subdistribution hazard ratio for developing thromboembolism was calculated using the Fine-Gray model with death as a competing risk. The hazard ratio for all-cause mortality was also calculated using the Cox proportional hazards model. RESULTS: Overall, VTE and ATE occurred in 761 (1.0%) and 389 (0.51%) patients, respectively; mortality was 11.7%. Propensity score overlap weighting demonstrated that the subdistribution hazard ratio (95% confidence interval) for VTE and ATE in the ICI group was 1.27 (1.01-1.60) and 0.96 (0.67-1.36), respectively, compared with the non-ICI group. The mortality hazard ratio in the ICI group was 0.68 (0.62-0.74). CONCLUSION: The addition of ICI to platinum combination therapy was associated with a higher risk of VTE compared with platinum combination therapy alone, while the risk of ATE might be comparable.
