RESUMEN
Pulmonary lymphangitis carcinomatosis is generally characterized by resistance to chemotherapy and is associated with a poor prognosis. Herein, we present a case of pulmonary lymphangitic carcinomatosis from recurrent breast cancer that responded well to trastuzumab deruxtecan(T-DXd). The patient was a 40-year-old woman with hormone receptor-positive, HER2-positive breast cancer. At the age of 31, she had undergone a left mastectomy with axillary lymph node dissection. She received adjuvant chemotherapy(5-fluorouracil-epirubicin-cyclophosphamide, docetaxel, and trastuzumab)followed by endocrine therapy(tamoxifen and LH-RHa). Three years after the surgery, pulmonary and bone metastases were detected and she was treated with trastuzumab, pertuzumab, and capecitabine. Liver metastases were detected, and she was treated with trastuzumab emtansine. Nine years after surgery, the patient developed dyspnea and was diagnosed with lymphangitis carcinomatosis. After initiating T-DXd, dyspnea rapidly improved, and ground glass opacity on CT scan disappeared. She responded well to the treatment, with prolonged, stable disease for 1 year and 2 months. Thus, T-DXd may be effective against pulmonary lymphangitis carcinomatosis, which is generally characterized by resistance to chemotherapy.

BACKGROUND: Infusion-related reactions (IRRs) are major side effects of rituximab administration. Male sex, high body weight, body surface area (BSA), and body mass index are predictive markers of rituximab-induced IRRs. However, as rituximab was not administered at a fixed dosage in a previous study, whether a higher dosage or factors associated with a larger physique are more strongly associated with rituximab-induced IRRs is unknown. MAIN BODY: Thirteen adults with frequently relapsing minimal change nephrotic syndrome (MCNS) who received an initial rituximab dose of 500 mg between September 2015 and November 2022 were retrospectively evaluated. Data on IRRs were collected from medical records. The incidence of rituximab-induced IRRs was 38.5% (5/13). The IRR group had a significantly higher BSA than the non-IRR group (median, 1.86 vs. 1.48 m2; p = 0.045). Additionally, rituximab dosage normalized by BSA in the IRR group was significantly lower than that in the non-IRR group (median, 268.8 vs. 337.9 mg/m2; p = 0.045). CONCLUSIONS: Our study revealed that adults with frequently relapsing MCNS who experienced IRRs tend to have a higher BSA, even with fixed-dose rituximab treatment. Therefore, when patients with higher BSA receive rituximab treatment, clinicians should be careful about monitoring patient condition whether the dosage is fixed or not.
RESUMEN
BACKGROUND: 5-aminolevulinic acid (5-ALA), a natural amino acid that is marketed alongside sodium ferrous citrate (SFC) as a functional food, blocks severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proliferation in vitro and exerts anti-inflammatory effects. In this phase II open-label, prospective, parallel-group, randomized trial, we aimed to evaluate the safety and efficacy of 5-ALA in patients with mild-to-moderate coronavirus disease 2019. METHODS: This trial was conducted in patients receiving 5-ALA/SFC (250/145 mg) orally thrice daily for 7 days, followed by 5-ALA/SFC (150/87 mg) orally thrice daily for 7 days. The primary endpoints were changes in SARS-CoV-2 viral load, clinical symptom scores, and 5-ALA/SFC safety (adverse events [AE] and changes in laboratory values and vital signs). RESULTS: A total of 50 patients were enrolled from 8 institutions in Japan. The change in SARS-CoV-2 viral load from baseline was not significantly different between the 5-ALA/SFC (n = 24) and control (n = 26) groups. The duration to improvement was shorter in the 5-ALA/SFC group than in the control group, although the difference was not significant. The 5-ALA/SFC group exhibited faster improvement rates in "taste abnormality," "cough," "lethargy," and "no appetite" than the control group. Eight AEs were observed in the 5-ALA/SFC group, with 22.7% of patients experiencing gastrointestinal symptoms (decreased appetite, constipation, and vomiting). AEs occurred with 750/435 mg/day in 25.0% of patients in the first phase and with 450/261 mg/day of 5-ALA/SFC in 6.3% of patients in the second phase. CONCLUSION: 5-ALA/SFC improved some symptoms but did not influence the SARS-CoV-2 viral load or clinical symptom scores over 14 days. The safety of 5-ALA/SFC in this study was acceptable. Further evaluation using a larger sample size or modified method is warranted.

Background: The kidneys are one of the organs most commonly affected by blunt trauma; however, the anatomical variations that predispose kidney injury are poorly understood. Case Presentation: An 80-year-old Japanese woman with lumber scoliosis was brought to our hospital because of severe flank pain after a minor fall at home. Contrast-enhanced computed tomography showed a severe left kidney laceration at the level of an acute angle in the vertebral column caused by scoliosis. Extravasation of contrast medium from the left renal artery branches was also noted. Selective arterial embolization achieved hemostasis. The patient was transferred to a rehabilitation facility without sequelae. Conclusion: Patients with scoliosis could be at higher risk of severe kidney laceration because of intrusion of the vertebral column into the retroperitoneal space. Therefore, even after low-impact trauma, active exploration for kidney injury could be warranted in patients with spinal curvature disorders.
RESUMEN
A prolonged activated partial thromboplastin time (APTT) is observed in patients with severe fever with thrombocytopenia syndrome (SFTS) and is one of the risk factors for severe disease. The mechanism underlying a prolonged APTT is largely unknown. The presence of antiphospholipid (aPL) antibodies in various viral infections has been documented but never reported in a patient with SFTS. We herein report the first SFTS patient with APTT prolongation and concurrent transiently positive aPL antibodies (lupus anticoagulants and anticardiolipin antibodies) with no coagulation factor deficiency.

A 54-year-old male with severe hypoxia was transferred to our hospital after choking on a mochi. Chest computed tomography revealed negative pressure pulmonary edema without pneumothorax. Endotracheal intubation was performed, and pressure-controlled ventilation was initiated. Following admission to the intensive care unit, his respiratory condition was stable in both the supine and left decubitus positions. However, every time he was placed in the right decubitus position, the tidal volume decreased by half, and SpO2 dropped rapidly to 80%, which recovered soon after returning to the supine position. Chest radiography was performed the following day, revealing grade II right pneumothorax, and a chest tube placement stabilized his respiratory status in the right decubitus position. Air leakage ceased within a few hours. Extubation was successful on the fifth hospital day, and the chest tube was removed on the eighth hospital day. To our knowledge, there are no previous reports on position-dependent symptoms of pneumothorax during mechanical ventilation. Clinicians should consider the possibility of pneumothorax on that same side when respiratory deterioration is observed only in one lateral decubitus position during mechanical ventilation.
RESUMEN
Post-intensive care syndrome (PICS) comprises physical, mental, and cognitive disorders following a severe illness. The impact of PICS on long-term prognosis has not been fully investigated. This study aimed to: (1) clarify the frequency and clinical characteristics of PICS in sepsis patients and (2) explore the relationship between PICS occurrence and 2-year survival. Patients with sepsis admitted to intensive care unit were enrolled. Data on patient background; clinical information since admission; physical, mental, and cognitive impairments at 3-, 6-, and 12-months post-sepsis onset; 2-year survival; and cause of death were obtained from electronic medical records and telephonic interviews with patients and their families. At 3 months, comparisons of variables were undertaken in the PICS group and the non-PICS group. Among the 77 participants, the in-hospital mortality rate was 11% and the 2-year mortality rate was 52%. The frequencies of PICS at 3, 6, and 12 months were 70%, 60%, and 35%, respectively. The 2-year survival was lower in the PICS group than in the non-PICS group (54% vs. 94%, p < 0.01). More than half of the survivors had PICS at 3 and 6 months after sepsis. Among survivors with sepsis, those who developed PICS after 3 months had a lower 2-year survival.
RESUMEN
Managing mild illness in COVID-19 and predicting progression to severe disease are concerning issues. Here, we investigated the outcomes of Japanese patients with mild COVID-19, and identified triage risk factors for further hospitalization and emergency department (ED) visits at a single tertiary hospital. A triage checklist with 30 factors was used. Patients recommended for isolation were followed up for 10 days for subsequent ED visits or hospital admission. Overall, 338 patients (median age, 44.0; 45% women) visited the clinic 5.0 days (median) after symptom onset. Thirty-six patients were immediately hospitalized following triage; others were isolated. In total, 72 non-hospitalized patients visited the ED during their isolation, and 30 were hospitalized after evaluation for oxygen desaturation. The median ED visit and hospitalization durations after symptom onset were 5.0 and 8.0 days, respectively. The checklist factors associated with hospitalization during isolation were age > 50 years, body mass index > 25 kg/m2, hypertension, tachycardia with pulse rate > 100/min or blood pressure > 135 mmHg at triage, and >3-day delay in hospital visit after symptom onset. No patients died. Altogether, 80% of patients with mild COVID-19 could be safely isolated at home. Age, BMI, underlying hypertension, date after symptom onset, tachycardia, and systolic blood pressure at triage might be related to later hospitalization.
RESUMEN
Secondary cold agglutinin syndrome (CAS) is autoimmune hemolytic anemia secondary to infections and lymphoid disorder. We here report the first Asian case of CAS secondary to novel coronavirus disease 2019 (COVID-19). A 72-year-old Japanese woman presented with a 2-week history of dyspnea and cough, and laboratory data revealed severe hemolytic anemia with a hemoglobin level of 4.7 g/dL. She was diagnosed with COVID-19, CAS, and monoclonal gammopathy of undetermined significance (MGUS). The anemia responded to corticosteroids administered for COVID-19 and required maintenance therapy. Although corticosteroids are not a standard therapy for CAS, they might be effective for CAS secondary to COVID-19 complicated with MGUS.

BACKGROUND: Foscarnet is an important drug for the treatment of cytomegalovirus infection in patients undergoing hematopoietic stem cell transplantation (HSCT). Foscarnet is often discontinued because of the development of acute kidney injury (AKI). Thus, the identification of factors leading to the development of AKI is beneficial. This study aimed to investigate the incidence of AKI and the factors influencing AKI development in HSCT patients treated with foscarnet. METHODS: This was a retrospective observational study. Patients who underwent HSCT and received foscarnet at the Department of Hematology, Osaka City University Hospital, were identified from medical records. The patients were classified into AKI and non-AKI groups, and the risk factors associated with AKI were evaluated. For continuous variables, receiver-operating characteristic (ROC) curve analysis was used to calculate the optimal cutoff value. RESULTS: Thirty-five patients (47 cases) were assigned to the AKI (51.1%, 24/47) and non-AKI groups (48.9%, 23/47). The AKI group had a significantly longer foscarnet administration period than the non-AKI group (p = 0.049). The appropriate cutoff value for the foscarnet administration period using the ROC curve was 27 days. The incidence of AKI was significantly higher in cases who received foscarnet for more than 27 days (11/14, 78.6%) compared to those who received less than 27 days (13/33, 39.4%) (odds ratio: 5.64, 95% confidence interval 1.32-24.2, p = 0.024). CONCLUSION: The incidence of AKI was 51.1% in HSCT patients treated with foscarnet, and foscarnet administration for more than 27 days may be associated with the incidence of AKI.

Vascular injury associated with cannulation during extracorporeal membrane oxygenation (ECMO) induction is a rare but life-threatening complication. The presence of abnormal vascular anatomy increases the risk of vascular injury and should be recognized before cannulation. We report the case of a patient with coronavirus disease (COVID-19) who was expected to undergo ECMO. By performing computed tomography (CT), we identified the absence of right superior vena cava (RSVC) with a persistent left superior vena cava (PLSVC) that could have caused serious complications associated with ECMO cannulation. PLSVC is observed in less than 0.5% of the general population; however, the combination of PLSVC and an absent RSVC in visceroatrial situs solitus is extremely rare. Attempting cannulation for Veno-venous (VV)-ECMO from the right (or left) internal jugular vein to the right atrium may cause serious complications. Cannulation may fail or lead to complications even in patients with inferior vena cava malformations. Although these vascular abnormalities are rare, it is possible to avoid iatrogenic vascular injury by identifying their presence in advance. Since anatomical variations in the vessels from the deep chest and abdominal cavity cannot be visualized using chest radiography and ultrasonography, we recommend CT, if possible, for patients with severe respiratory failure, including those with COVID-19, who may be considered for VV-ECMO induction.

A new correction algorithm for closed orbit distortion based on an adaptive feedforward control (AFC) has been developed. At SPring-8, two helicity-switching twin-helical undulators (THUs) had been implemented with conventional feedforward corrections. However, the validity of these corrections turned out to be expiring due to unforeseen variation in the error magnetic fields with time. The developed AFC system has been applied to the THUs dynamically updating the feedforward table without stopping the helicity switching amid user experiments. The error sources in the two THUs are successfully resolved and corrected even while the two THUs are switching simultaneously with the same repetition period. The actual operation of the new AFC system enables us to keep the orbit variations suppressed with an accuracy at the sub-micrometre level in a transparent way for light source users.
RESUMEN
A previously healthy Japanese man in his fifties was admitted to our hospital because of a recurrent fever after returning from Kenya and Madagascar. He was ambulant with a body temperature of 36.6 °C. His physical examination revealed normal except for tender hepatomegaly. The blood test results showed no apparent abnormality except thrombocytopenia and mild liver dysfunction. The rapid diagnostic test and Giemsa-stained blood film were repeatedly negative for malaria. Computed tomography scans of the chest, abdomen, and pelvis revealed no significantly abnormal findings.
RESUMEN
A Japanese man in his 60s presented with complaints of epigastric pain and weight loss. A gastrointestinal endoscopy revealed multiple gastric ulcers and an irregular mound located on the wall of the lower gastric body along the greater curvature, which was suspected to be cancerous. A biopsy revealed that it was a Group 2 tumor even though the biopsy was repeated 4 times. He was referred to our hospital and 3 biopsies were performed. The final result classified the tumor as Group 4. The patient underwent surgery and the pathological examination revealed an extremely well-differentiated adenocarcinoma( EWDA). An EWDA is characterized by a well-formed mucinous gland with little or no nuclear atypia, which makes preoperative biopsy diagnosis difficult.

BACKGROUND: Multimorbidity is the presence of two or more chronic diseases and is associated with increased adverse outcomes, including hospitalization, mortality and frequency of use of medical institutions. OBJECTIVE: This study aimed to describe multimorbidity patterns, determine whether multimorbidity was associated with high medical expenditure, and determine whether mental diseases had an interaction effect on this association. METHODS: We conducted a claims data-based observational study. Data were obtained for 7526 individuals aged 0-75 years from a medical claims data set for Goto, Japan, over a 12-month period (2016-17). Annual medical expenditure was divided into quintiles; the fifth quintile represented high medical expenditure. Multimorbidity status was defined as the occurrence of two or more health conditions from 17 specified conditions. Odds ratios (OR) and 95% confidence intervals (CI) for high medical expenditure were calculated by number of comorbidities. RESULTS: In total, 5423 (72.1%) participants had multimorbidity. Multimorbidity was significantly associated with high medical expenditure, even after adjustment for age, sex and income category (OR: 10.36, 95% CI: 7.57-14.19; P < 0.001). Mental diseases had a significant interaction effect on the association between multimorbidity and high medical expenditure (P = 0.001). CONCLUSIONS: Multimorbidity is associated with high medical expenditure in Japan. Mental diseases may contribute to increased medical costs.

BACKGROUND: Concomitant use of foscarnet and intravenous pentamidine can very frequently cause severe hypocalcemia. However, it is unknown whether aerosolized pentamidine has a similar adverse interaction with foscarnet. The present study was aimed at examining the safety profile of concomitantly used foscarnet and aerosolized pentamidine in patients receiving allogeneic hematopoietic stem cell transplantation. METHODS: Data from allogeneic hematopoietic stem cell recipients who had been administered foscarnet therapy for over 7 days were analyzed. We compared electrolyte abnormalities and serum creatinine level between patients who received aerosolized pentamidine concomitantly and those who did not. RESULTS: A total of 84 consecutive patients and 135 episodes of foscarnet therapy between May 2011 and April 2016 were evaluable. Of these 135 episodes, 25 episodes of therapy included concurrent therapy with 300 mg dose of aerosolized pentamidine once a month (pentamidine group) and 110 episodes did not (non-pentamidine group). The incident rates of grade 3/4 hypocalcemia did not significantly differ between the pentamidine and non-pentamidine groups (P = .207; 0/25 [0%] vs 10/110 [9.1%], respectively). In addition, we observed no significant difference in the incident rates of grade 3/4 serum creatinine increase between the two groups (P = 1.00; 0/25 [0%] vs 4/110 [3.6%], respectively). CONCLUSION: Our results suggest that the drug interactions between foscarnet and aerosolized pentamidine may not be clinically significant.

A woman in her 50s was admitted to our hospital with fever and lower abdominal swelling. Abdominal CT/MRI examinations revealed irregular thickening of the transverse colon wall, which was attached to a subcutaneous abscess. An abdominal wall mass, a patent urachus, and a tumor in the 5th segment of the liver were also noted. Colonoscopy revealed type 2 advanced transverse colon cancer. The solitary, sessile tumor was observed at the apex of the bladder under cystoscopy, suggesting the formation of the urachal carcinoma. Transcutaneous liver biopsy obtained from the liver tumor indicated adenocarcinoma, which was morphologically different from the existing transverse colon cancer. Right hemicolectomy with resection of the umbilicus, abdominal wall, urachus, and part of the bladder wall was performed. Diagnosis of the transverse colon cancer invading the abdominal wall and bladder was confirmed by histopathological examination. Hepatectomy was performed in the next surgery, and the tumor was histopathologically diagnosed as an intrahepatic cholangiocarcinoma. Both the transverse colon cancer and the intrahepatic cholangiocarcinoma were radically resected. Radical surgical diagnostic resection may be valuable in cases of multicentric cancers of unknown primary origin, if radical resection of each individual tumor is required.

X-ray free-electron laser (XFEL) pulses from SPring-8 Ångstrom Compact free-electron LAser (SACLA) with a temporal duration of <10 fs have provided a variety of benefits in scientific research. In a previous study, an arrival-timing monitor was developed to improve the temporal resolution in pump-probe experiments at beamline 3 by rearranging data in the order of the arrival-timing jitter between the XFEL and the synchronized optical laser pulses. This paper presents Timing Monitor Analyzer (TMA), a software package by which users can conveniently obtain arrival-timing data in the analysis environment at SACLA. The package is composed of offline tools that pull stored data from cache storage, and online tools that pull data from a data-handling server in semi-real time during beam time. Users can select the most suitable tool for their purpose, and share the results through a network connection between the offline and online analysis environments.
RESUMEN
OBJECTIVES: This report provides an experimental protocol for a study designed to verify the effects of yoga exercise and a nutritional guidance program during pregnancy on several key pregnancy and birth outcomes among Japanese women. DESIGN: This is a study protocol of a randomized controlled trial. SETTING/LOCATION: This intervention will be carried out in a university hospital in Tokyo. SUBJECTS: Healthy primiparous women will be recruited at 18-23 gestational weeks in the hospital. A total of 400 participants will be randomly assigned to one of four groups in this trial, with 100 participants in each group-group with yoga exercise, with nutritional guidance, with both yoga and nutritional guidance, and with standard care alone, as the control group. Yoga exercise consists of yoga classes held at the hospital 3 or 5 days a month, duration 60 min, and home practice using a digital video disk, duration 30 or 60 min per session. We recommend participants do yoga at least 3 days a week for a total of 60 min per day. Nutritional guidance is based on individual dietary intake assessed using a brief-type diet history questionnaire. RESULTS: The primary outcome is rate of pregnant women with adequate gestational weight gain. Secondary outcomes include physiologic and psychologic status assessed via biomarkers and health-related scales, dietary nutrition intake, and birth outcomes. CONCLUSIONS: This study shows the effects of a yoga exercise and nutritional intervention. If the intervention is found to be effective, our results will be useful for healthcare providers and pregnant women.

We report a rare case of esophageal carcinoma with gastric wall metastasis. A 73-year-old man with dysphagia underwent endoscopy and upper GI series and chest-abdominal computed tomography, revealing esophageal carcinoma and gastric cancer, which was diagnosed as squamous cell carcinoma by biopsy. The esophageal carcinoma was located in the lower thoracic esophagus(Lt). Total gastrectomy was performed. The resected specimen showed a type 3 tumor measuring 7×7 cm in the anterior wall of the stomach. Pathologically, the depth of invasion of the stomach was SE. He died 3 months after the operation. Esophageal carcinoma with gastric intramural metastasis is very rare and has a dismal prognosis. We report a rare case of esophageal carcinoma with large intramural metastasis to the stomach.
