In-depth proteomics reveals the characteristic developmental profiles of early lung adenocarcinoma with epidermal growth factor receptor mutation. Cancer Med 2023; 12:10755-10767. [PMID: 37004157 DOI: 10.1002/cam4.5766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 02/11/2023] [Accepted: 02/22/2023] [Indexed: 04/03/2023] Open
Abstract
INTRODUCTION Lung adenocarcinoma progresses stepwise from atypical adenomatous hyperplasia to adenocarcinoma in situ (AIS), followed by minimally invasive adenocarcinoma (MIA), and then obvious invasive adenocarcinoma. In this study, we examined the protein expression profiles of early and epidermal growth factor receptor (EGFR) mutation-positive lung adenocarcinomas. METHODS Fifteen cases of small and EGFR mutation-positive adenocarcinomas were collected, including AIS, MIA, and small invasive adenocarcinoma (SIA). We examined their protein expression profiles by tandem mass tag (TMT)-labeling liquid chromatography-mass spectrometry (LC-MS/MS) and compared the results between AIS and MIA versus SIA. The differentially expressed proteins were then verified by Western blot analysis and immunohistochemistry (IHC). The clinicopathological implications of the proteins were also examined by IHC. RESULTS A total of 4220 proteins were identified by LC-MS/MS analysis. Pathway analysis of the differentially expressed proteins revealed that pathways related to interferon α/β signaling, glutamate and glutamine metabolism, and gluconeogenesis were upregulated in SIA relative to AIS. Among the 13 differentially expressed proteins, cellular retinoic acid binding protein 2 (CRABP2), delta(24)-sterol reductase (DHCR24), and adenylate kinase 4 (AK4) were expressed significantly more strongly in SIA than in AIS. Patients with high expression of CRABP2, DHCR24, and AK4 showed a significantly poorer outcome than those with low expression. CONCLUSION In comparison with AIS, SIA shows differences in several different protein expression pathways. Furthermore, CRABP2, DHCR24, and AK4 are useful IHC markers for diagnosis of lung adenocarcinoma invasiveness and may be associated with malignant progression of AIS.

Infantile Kaposiform hemangioendothelioma in a female patient complicated with severe obstructed jaundice: a case report. Surg Case Rep 2022; 8:225. [PMID: 36580178 PMCID: PMC9800675 DOI: 10.1186/s40792-022-01581-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 12/20/2022] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Kaposiform hemangioendothelioma (KHE) is a rare locally aggressive vascular neoplasm that occurs mainly in the pediatric population. KHE usually originates just underneath the skin and affects deeper tissues through infiltrative growth; however, visceral tissue involvement is quite rare. CASE PRESENTATION An 8-month-old girl with jaundice and acholic stool was referred to our hospital for further evaluation of a hepatoduodenal ligament tumor. A blood examination revealed high bilirubin and liver enzyme levels, but no signs of coagulopathy. The first attempt at a diagnostic surgical procedure did not provide sufficient diagnostic information. However, the histopathological diagnosis of the cystic duct excised in the second surgery indicated KHE. Therefore, in our case, KHE was considered a cause of obstructive jaundice. Sirolimus (rapamycin) was initiated, and the patient was discharged 7 months after admission. CONCLUSIONS In cases of atypical hypervascular lesions in the abdominal cavity, especially in the pediatric population, it is important to consider the possibility of KHE, and surgical intervention with proper strategies is required for diagnosis, followed sequentially by promising treatments.

Abstract
BackgroundTakayasu arteritis (TAK), a granulomatous large vessel vasculitis, mainly involves the aorta and its proximal branches and commonly occurs in young females. However, studies of pregnancy in women with TAK are sparse and limited, probably due to the rarity of the disease.ObjectivesThe purpose of this study was to understand the status quo of medical treatments of the primary disease and outcomes of pregnancy in patients with TAK, and birth outcomes of the children in Japan.MethodsPatients with TAK who conceived after the onset of the disease and were managed at medical facilities participating in the Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS) were retrospectively enrolled in this study. The following information was collected from patients who had a live-born baby: age at diagnosis of TAK, disease classification, age at delivery, treatments before and during pregnancy, complications during pregnancy, birth outcomes of the children, and changes in disease activity during pregnancy and after delivery.ResultsFifty-one cases and 69 pregnancies from 19 ethics committee-approved centers were enrolled during the study period 2019–2021. Of these, 49 cases and 66 pregnancies (95.7%) resulted in delivery and live-born babies. The Numano classification of the 49 cases was as follows: type I, 11; type IIa, 15; type IIb,12; type III, 1; type IV, 1; type V, 9; with type IIa being the most common. The age of diagnosis was 22 years (13–37 years, year of diagnosis 1965–2017), the median age of the delivery of 66 pregnancies was 31 years (year of delivery 1969-2021), and the median duration of illness at delivery was nine years. There were 34 planned pregnancies (51.5%, including four pregnancies by artificial insemination/ovulation induction). Preconception therapy included prednisolone (PSL) in 51 pregnancies (77.3%, median dose 7.5 mg (range 4–30 mg)/day), immunosuppressive drugs in 18 pregnancies (27.3%, azathioprine 8, tacrolimus 7, methotrexate 4, cyclosporin A 1, and colchicine 1), biologics in 12 pregnancies (18.1%, infliximab 6, tocilizumab 5, and adalimumab 1), antihypertensive drugs in 5 pregnancies (7.6%). Surgical treatment had been performed before pregnancy in 6 cases (aortic root replacement 2, subclavian artery dilatation 1, subclavian artery bypass 1, subclavian artery stenting 1, and ascending aorta semicircular artery replacement 1). Medications used during the course of pregnancy included PSL in 48 pregnancies (72.7%, median dose 8 mg (range 4–30 mg)/day, increased in 13 pregnancies, decreased in 1 pregnancy), immunosuppressants in 13 pregnancies (19.7%, azathioprine 6, tacrolimus 6, and cyclosporin A 1), biologics 9 pregnancies (13.6%, infliximab 4, tocilizumab 4, and adalimumab 1). Immunosuppressants and biologics were discontinued in five and four pregnancies after conception. Complications during pregnancy were observed in 20 pregnancies (30.3%), with hypertension being the most common. Complications related to TAK or its treatment were severe infections in two pregnancies and aneurysm enlargement due to increased circulating plasma volume in one pregnancy. Aortic arch replacement was performed after delivery for the latter case. Relapse of TAK was observed in 4 pregnancies (6.1%) during pregnancy and in 8 pregnancies (12.1%) after delivery. One pregnancy resulted in restenosis of subclavian artery for which dilatation procedure was performed prior to the pregnancy. There were 13/66 (19.7%) preterm infants and 17/59 (28.8%) low birth weight infants; all but one had a birth weight of more than 2,000 g and no had serious postnatal abnormalities. Forty-three (82.7%) of the 52 confirmed infants were breastfeed fully or mixed.ConclusionMost of the pregnancies in patients with TAK were successfully delivered while they had low disease activity at a dose of less than 10 mg/day of PSL. Relapse occurred during pregnancy and after delivery in some cases. The babies tended to have low birth weight, but 82.7% of them were breastfed without serious complications.Disclosure of InterestsTakako Miyamae: None declared, Yusuke Manabe: None declared, takahiko sugihara Speakers bureau: TS has received honoraria from Abbvie Japan Co., Ltd., AsahiKASEI Co., Ltd., Astellas Pharma Inc., Ayumi Pharmaceutical, Bristol Myers Squibb K.K., Chugai Pharmaceutical Co., Ltd., Eli Lilly Japan K.K., Mitsubishi-Tanabe Pharma Co., Ono Pharmaceutical, Pfizer Japan Inc., Takeda Pharmaceutical Co.

Immunological features and complications in patients with glycogen storage disease 1b after living donor liver transplantation. Pediatr Transplant 2021; 25:e14104. [PMID: 34339091 DOI: 10.1111/petr.14104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 06/11/2021] [Accepted: 07/08/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND LT is an elective treatment choice for children diagnosed with GSD1b that can improve their quality of life and stabilize their glucose intolerance. However, careful attention should be paid to immunosuppression after LT due to the susceptibility to infection because of neutropenia and neutrophil dysfunction in GSD1b patients. This study revealed the immunological features and complications in the early post-LT period. METHODS We compared findings between 11 (1.9%) children with GSD1b and 273 children with BA. Analyses using the PSM were performed to overcome selection bias. RESULTS Despite persistent low tacrolimus trough levels in GSD1b patients, none of these children developed TCMR within 1 month after LDLT (GSD1b: 0/11 [0%] vs. BA: 86/273 [31.5%], p = .038). This result was also confirmed in PSM. The incidence of bloodstream infections was higher in GSD1b patients than in BA patients in the early phase of the post-transplant period (GSD1b: 4/11 [36.4%] vs. BA: 33/273 [12.1%], p = .041), but not reach statistical significance in PSM. In a phenotypic analysis, the ratio of CD8+ T cells in GSD1b recipients' peripheral blood mononuclear cell samples was lower than in recipients with BA through the first month after LDLT. CONCLUSIONS We found that GSD1b recipients were more likely to develop postoperative bloodstream infection than recipients with BA but did not experience TCMR despite low tacrolimus levels in the early post-LDLT period. A tailored immunosuppression protocol should be prepared for GSD1b recipients after LDLT.

The extracorporeal circulation with transdiaphragmatic approach in living-donor liver transplantation for HB with atrial extension of tumor thrombus: A case report. Pediatr Transplant 2021; 25:e13948. [PMID: 33326681 DOI: 10.1111/petr.13948] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 10/30/2020] [Accepted: 11/23/2020] [Indexed: 12/17/2022]
Abstract
Surgical intervention for HB with tumor thrombi extending into the IVC and the RA might requires careful planning of the surgical procedures, including vascular reconstruction and extracorporeal circulation. We herein report a successful case of LDLT for HB with atrial extension of a tumor thrombus by extracorporeal circulation with a transdiaphragmatic approach. The patient was a 5-year-old boy with PRETEXT IV HB with a tumor thrombus that extended into the IVC and the RA. After 4 cycles of chemotherapy and resection of bilateral lung metastases, the size of the primary HB tumor decreased. As the tumor extension from the LHV to the RA had decreased but was still present, we performed LDLT with tumor thrombectomy. The central part of the diaphragm was sagittally incised to expose the suprahepatic IVC and the RA. Venovenous bypass was achieved from the right femoral vein and IMV to the RA En bloc resection of the native liver with the tumor thrombus was then performed. HV anastomosis was made between the newly created orifice on the IVC and the graft LHV. The duration of LDLT was 10 hours and 44 minutes (extracorporeal circulation time: 78 minutes). Pediatric LT for HB with the extension of tumor thrombi into the RA under extracorporeal circulation is a feasible option and allows for the expansion of the indications for transplantation for children with unresectable liver tumors.

Fatal Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis with virus-infected T cells after pediatric multivisceral transplantation: A proof-of-concept case report. Pediatr Transplant 2021; 25:e13961. [PMID: 33368911 DOI: 10.1111/petr.13961] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 11/28/2020] [Accepted: 12/07/2020] [Indexed: 01/17/2023]
Abstract
BACKGROUND EBV-associated HLH driven by EBV-infected CD8+ T cells is a rare complication after pediatric solid organ transplantation. The etiology and disease spectrum of post-transplant EBV-HLH are poorly understood, and making a precise diagnosis and providing optimal treatment remain a challenge. METHODS/CASE DESCRIPTION/RESULTS We report a 2-year-old multivisceral transplant recipient who developed fever and cytopenia with a persistent high EBV-load state. Repeated tissue examinations and CT scans could not identify a localized mass, which is the key to the diagnosis of PTLD as per the WHO classification. Hence, EBV-HLH was diagnosed by clinical manifestations as well as characterization of EBV-infected cells, pathological examination on cell block of pleural effusion and clonality analysis. This EBV-HLH did not respond to intensive chemotherapy, resulted in the recipient's death, acting similarly to hematological malignancy. CONCLUSIONS Characterization of EBV-infected cells in peripheral blood should be considered when persistent high EBV loads develop with symptoms consistent with PTLD, but no evidence of localized mass, and the tissue diagnosis is unavailable after pediatric solid organ transplantation.

Abstract
BACKGROUND AND AIM The incidence of non-alcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC) is progressively increasing. However, the pathophysiology and etiology of NASH progression to HCC are unknown. We hypothesized that steatosis was the key factor in NASH-related hepatocarcinogenesis and aimed to evaluate the effects of long-term liver X receptor (LXR) agonist stimulation on hepatic steatosis induced by a high-fat diet and oxidative stress. METHODS We used an LXR agonist (T0901317) and CCl4 to induce hepatic steatosis and oxidative stress, respectively. C57BL/6 mice fed with a high-fat diet were treated with either T0901317 + CCl4 (T09 + CCl4 group) or CCl4 alone (CCl4 group). T0901317 (2.5 mg/kg) and CCl4 (0.1 mL/kg) were intraperitoneally administered twice weekly for 24 weeks. RESULTS The liver-to-body weight ratio was significantly higher in the T09 + CCl4 group than in the CCl4 group. Mice in the T09 + CCl4 group exhibited abnormal lipid metabolism and NASH-like histopathological features. Additionally, all mice in the T09 + CCl4 group developed liver tumors diagnosed as well-differentiated HCC. The genes identified via microarray analysis were related to NASH and HCC development. CONCLUSIONS By combining long-term LXR agonist stimulation with oxidative stress and a high-fat diet, we successfully reproduced liver conditions in mice similar to those in humans with NASH and progression to HCC. Our results provide new insight into NASH-related HCC progression and therapy.

Abstract
CASE
A 18-month-old boy presented with approximately 2 months history of progressive left hemiparesis and left exotropia. MRI study showed a 3–4 cm T1-iso, T2-high tumor at right thalamus to midbrain with little contrast enhancement. The patient underwent endoscopic biopsy of the tumor, which showed relatively dense proliferation of small cells with round nuclei, mitosis of the tumor cell, but no necrosis. Immunohistochemical showed positive stain of GFAP and Olig2. Ki-67 was 34%. The histopathological diagnosis was compatible with high grade glioma. Chemotherapy with vincristine, cyclophosphamide, cisplatin and etoposide was initiated. Molecular testing of the tumor revealed H3F3A K27M and BRAF V600E double mutations in DNA from frozen tumor tissue.
DISCUSSION
The concurrent mutation of H3F3A K27M and BRAF V600E in pediatric glioma is very rare, but there are several cases previously reported in literature. Interestingly those cases are heterogenous in age, location, histopathological subtypes and clinical outcome.

Abstract
X-linked myotubular myopathy (MTM) (OMIM 310400) is a severe neuromuscular disorder caused by mutations in the myotubularin (MTM1) gene. Liver hemorrhaging due to peliosis hepatis (PH) is a fatal complication. We herein report 2 successful cases of living-donor liver transplantation (LDLT) for MTM patients due to liver hemorrhaging caused by PH and review previous reports. A boy who was 9 years and 4 months old initially underwent left lateral segmentectomy due to massive hepatic and intraperitoneal hemorrhaging. As bleeding from the remnant liver continued after hepatectomy, this patient emergently underwent LDLT using a left lateral segment graft from his father. Another boy who was 1 year and 7 months old underwent transcatheter arterial embolization due to hepatic hemorrhaging and was referred to our hospital for LDLT using a left lateral segment graft from his father. The pathological findings in both cases showed sinusoidal dilatation with degenerative changes in reticular fiber and hematoma in the explanted liver, which were consistent with PH associated with MTM. LT should be considered as a treatment option for patients with episodes of hepatic hemorrhaging due to MTM in order to protect against fatal bleeding.

Living-donor liver transplantation providing an adequate chemotherapy for a pediatric patient with anaplastic large cell lymphoma complicated with liver failure due to the aggravation of biliary hepatopathy by secondary hemophagocytic lymphohistiocytosis. Int J Hematol 2020; 112:900-905.

Abstract
Anaplastic large cell lymphoma (ALCL) accounts for 10-15% of childhood non-Hodgkin lymphoma cases; it is generally chemo-sensitive and is one of the most curable pediatric cancers. We report here a case of pediatric ALCL complicated with acute liver failure due to the aggravation of pre-existing biliary hepatopathy by lymphoma-associated hemophagocytic lymphohistiocytosis (HLH). Although the initial treatment response against ALCL was very good, poor and irreversible liver function due to biliary cirrhosis worsening by lymphoma-associated HLH prevented the patient from receiving further consolidation chemotherapies. To make matters worse, his condition was accompanied with intrahepatic fungal pseudoaneurysm and invasive fungal infection. Thus, we decided to perform an urgent living-donor liver transplantation from his father to correct the patient's liver function and make it possible to proceed with further ALCL therapy. After the living-donor liver transplantation, the patient successfully received consolidation therapy with brentuximab vedotin. To our knowledge, this may be an early reported case of a pediatric patient undergoing liver transplantation during treatment for ALCL. In most patients with HLH-associated ALCL, liver function improves when ALCL is controlled. However, acute liver failure is occasionally observed in HLH cases with pre-existing liver dysfunction. In such cases, liver transplantation should be considered to correct liver dysfunctions if the disease control of HLH is satisfactory.

Abstract
Background:Since the number of polyarteritis nodosa (PAN) patients is small not only in Japan but also in the world, the characteristics of PAN have not been fully clarified and appropriate treatment has not been established.Objectives:This study aimed to describe the epidemiological and clinical features and treatment of patients with PAN in Japan.Methods:We used the database of the Ministry of Health, Labour and Welfare (MHLW) in 2013 and 2014. Data of 178 patients who fulfilled the diagnostic criteria by MHLW and had registered within a year after onset of PAN was analyzed.Results:The analysis included 75 males and 103 females, with a mean age of 64.5 ± 20.3 years. PAN was diagnosed by clinical symptoms in 27.6% of the patients, 11.5% of the patients by pathological findings, and the rest of the patients by both. Pathological examination was performed in 71.3% of the patients, of whom 11.2% had evidence of necrotizing vasculitis of the small and medium arteries. As a systemic symptom, fever was observed in 55.2% of cases. As organ symptoms, muscle and joint symptoms (74.7%), skin symptoms (73.0%), neuropsychiatric symptoms (50.0%), respiratory symptoms (32.6%), and renal symptoms (19.7%) were common. Patients aged 65 or older had a higher rate of systemic, renal and respiratory symptoms, and lower rate of skin symptoms compared with the patients younger than 65. Patients with renal symptoms had a high prevalence of respiratory, cardiac and ocular symptoms, while those with respiratory symptoms had a high prevalence of systemic and cardiac symptoms. Laboratory findings showed that MPO- and/or p-ANCA positive rate was 30.5% and PR3- and/or c-ANCA positive rate was 11.0%. The Hepatitis B antigen positive rate was 3.9%. Angiography was performed in 20.7%, among which 27.0% were found to have multiple small aneurysms, wall irregularities and stenosis at the abdominal aortic branches. Glucocorticoids were used for treatment in all cases with an average maximum prednisolone dose of 32.5 mg/day. Concomitant immunosuppressants were used in 28.7%, half of which was cyclophosphamide. In other cases, azathioprine or methotrexate was used. Immunosuppressants have been used more frequently in patients with systemic symptoms and nasal and ear symptoms. Among the immunosuppressants, cyclophosphamide tends to be used for patients with higher CRP or patients with respiratory symptoms, and the maximum dose of glucocorticoids was significantly higher in patients who used cyclophosphamide compared to those who used other immunosuppressants.Conclusion:PAN developed in middle-aged and elderly people and exhibited various clinical symptoms. We found that common symptoms varied with age, and treatment options were determined depending on the types of organ symptoms and severity. Hepatitis B virus infection was rare in patients with PAN in Japan.References:None.Disclosure of Interests: :Mai Kawazoe: None declared, Toshihiro Nanki Grant/research support from: Chugai Pharmaceutical Co., Eisai Co., Ltd., Teijin Pharma Ltd., Eli Lilly Japan K.K., Bristol-Myers K.K., Ono Pharmaceutical Co., Ltd., Novartis Pharma K.K., Asahikasei Pharma Corp., Mitsubishi-Tanabe Pharma Co., Astellas Pharma Inc., Ayumi Pharmaceutical Co., Pfizer Japan Inc., Daiichi Sankyo Co., Ltd., Shionogi & Co., Ltd., Sanofi K.K., Nippon Kayaku Co., Ltd., Yutoku Pharmaceutical Ind.

Abstract
Abstract
Background
Informing heart failure (HF) patients about their prognosis is an important part of clinical management, particularly at the time of hospitalization. Current European Society of Cardiology guidelines recommend communicating this information to HF patients at the time of hospitalization and with any change in clinical status. However, little is known about actual patient preferences, understanding, and attitudes towards prognostic communication with their treating physicians.
Methods
We surveyed 113 consecutive hospitalized HF patients in a single university hospital. We assessed patient understanding of prognosis (likelihood of survival beyond 2 years), and compared patient expectations to model predictions. Model-predicted 2-year survival rate was calculated by the Seattle Heart Failure Model (SHFM). We also assessed patient preferences for information disclosure using the Prognosis and Treatment Perception Questionnaire (PTPQ). The PTPQ assesses patient beliefs regarding 1) the importance of knowing about prognosis, 2) the importance of knowing about treatment option, and 3) frequency of having a conversation about prognosis during the hospital stay.
Results
Enrolled patients were predominantly male (65.5%), with a mean age of 73.6±9.6 years and mean left ventricular ejection fraction was 46.2±15.4%. Median SHFM-estimated 2-year survival rate was 89.2% (interquartile range: 83.8–92.9%). Overall, patient understanding about prognosis was suboptimal. Among patients with a guarded 2-year survival (SHFM <90%: N=60), 44% reported that their likelihood of 2-year survival was >90% (Figure; red box). However, among patients with favorable 2-year survival (>90%: N=53), 38% reported a likelihood of <90% (Figure; blue box). Regarding treatment options, most patients (98%) desired to learn as many details as possible. Responses varied with regard to information on individual prognosis; whereas 51% wanted to know more about prognosis than their present status alone, a significant number (28%) of subjects answered “never” or “less often” to a query on the frequency of discussion about prognosis. Patient preference for more information about prognosis was associated with female sex (odds ratio [OR]: 2.52; 95% confidence interval [CI]: 1.12–5.69), fewer symptoms of depression (1-point increase on Patient Health Questionnaire-2, OR: 0.66; 95% CI: 0.49–0.87), and previous stroke (OR: 2.92; 95% CI: 1.04–8.19), but not other social/demographic or clinical factors (e.g., age, education, caregiver support, HF phenotype and severity, and other comorbid conditions).
Figure 1
Conclusions
There were substantial discrepancies in patient understanding of prognosis and in desire for more information from physicians. Interventions to improve prognostic understanding are warranted for HF patients, and hospitalization for HF could represent an opportunity for optimization.

A case of invasive mucinous adenocarcinoma of the lung showing stepwise progression at the primary site. Lung Cancer 2019; 136:94-97. [PMID: 31472337 DOI: 10.1016/j.lungcan.2019.08.027] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 08/21/2019] [Accepted: 08/23/2019] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Invasive mucinous adenocarcinoma (IMA) is a variant of lung adenocarcinoma. We present one case of IMA with mixed mucinous and non-mucinous components, suggesting stepwise progression within the tumor. MATERIAL AND METHOD The two different components of IMA were separately examined by immunohistochemistry and performed amplicon sequencing (Ion Ampliseq Cancer Hotspot Panel v2, ilumina, San Diego, CA). RESULT Macroscopically, the IMA contained a small and well demarcated solid part. Tumor cells in the main part showed abundant intracytoplasmic mucin, whereas those in the solid part showed scant intracytoplasmic mucin and high-grade nuclear atypia. Both parts harbored the same KRAS p.G12 V mutation. The amplicon sequencing of the IMA showed oncogenic TP53 p.P278 L mutation was detected only in the solid part. CONCLUSION Oncogenetic TP53 mutation might promote stepwise progression of this case of IMA.

Cytoplasmic expression of epithelial cell transforming sequence 2 in lung adenocarcinoma and its implications for malignant progression. J Transl Med 2019; 99:551-567. [PMID: 30542068 DOI: 10.1038/s41374-018-0142-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 08/14/2018] [Accepted: 08/20/2018] [Indexed: 12/20/2022] Open
Abstract
Epithelial cell transforming sequence 2 (ECT2), a guanine nucleotide exchange factor, is predominantly localized in the nucleus of non-transformed cells and functions to regulate cytokinesis. ECT2 is also localized in the cytoplasm of cancer cells. Aberrant cytoplasmic expression of ECT2 is thought to drive tumor growth and invasion. In this study, we investigated the cytoplasmic expression of ECT2 and its prognostic and biological significance in lung adenocarcinoma. Western blotting of cellular fractions from the nucleus and cytoplasm was performed to determine the subcellular localization of ECT2 in lung adenocarcinoma cell lines. The cytoplasmic expression of ECT2 in 167 lung adenocarcinomas was evaluated by immunohistochemistry and its clinical significance was examined using Kaplan-Meier curves and Cox regression analysis. Scraping cytology specimens of 13 fresh lung adenocarcinomas were used to assess the subcellular localization of ECT2 and its phosphorylation at Thr790 (P-ECT2(T790)). We found that ECT2 was localized in both the nucleus and cytoplasm of lung adenocarcinoma cell lines and tumor tissues. Cytoplasmic expression of ECT2 was detected by immunohistochemistry in 83 (50%) of the lung adenocarcinomas, and was found to increase during cancer progression. It was expressed in 30 (29%) small adenocarcinomas ( ≤ 2 cm in diameter) and 53 (82%) advanced adenocarcinomas ( > 2 cm in diameter). Cytoplasmic positivity for ECT2 was associated with a poor outcome in terms of both disease-free and overall survival (both P < 0.001), and was an independent prognostic factor for overall survival (P = 0.025). Immunocytochemical staining for P-ECT2(T790) demonstrated cytoplasmic and membrane positivity in Calu-3 cells and scraping cytology specimens. Positive P-ECT2(T790) staining was correlated with cytoplasmic ECT2 expression in 6 of 13 scraped cytology specimens tested. In conclusion, our findings indicate that cytoplasmic ECT2 expression could promote the malignant progression of lung adenocarcinoma and may represent a potent therapeutic target for patients with lung adenocarcinoma.

Abstract
Aims The aim of this study was to assess the current evidence relating to the benefits of virtual reality (VR) simulation in orthopaedic surgical training, and to identify areas of future research. Materials and Methods A literature search using the MEDLINE, Embase, and Google Scholar databases was performed. The results' titles, abstracts, and references were examined for relevance. Results A total of 31 articles published between 2004 and 2016 and relating to the objective validity and efficacy of specific virtual reality orthopaedic surgical simulators were identified. We found 18 studies demonstrating the construct validity of 16 different orthopaedic virtual reality simulators by comparing expert and novice performance. Eight studies have demonstrated skill acquisition on a simulator by showing improvements in performance with repeated use. A further five studies have demonstrated measurable improvements in operating theatre performance following a period of virtual reality simulator training. Conclusion The demonstration of 'real-world' benefits from the use of VR simulation in knee and shoulder arthroscopy is promising. However, evidence supporting its utility in other forms of orthopaedic surgery is lacking. Further studies of validity and utility should be combined with robust analyses of the cost efficiency of validated simulators to justify the financial investment required for their use in orthopaedic training.

Abstract
It has been reported that N-myc downstream regulated gene 1 (NDRG1) is related to the prognosis of non-small cell lung cancer (NSCLC), and associated with c-Myc degradation in NSCLC cell lines. However, the relationship of NDRG1 to prognosis or c-Myc expression in lung adenocarcinoma has not been well clarified. The present study was designed to investigate the prognostic significance of NDRG1 and/or c-Myc expression in lung adenocarcinoma using immunohistochemistry with a tissue microarray. We examined 184 lung adenocarcinomas and observed low expression of NDRG1 in adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA), whereas high expression of NDRG1 was seen in invasive adenocarcinoma. Each of the clinicopathological features except age was significantly correlated with NDRG1 expression. Kaplan-Meier curves indicated that high expression of NDRG1 was significantly correlated with poor prognosis in comparison with low expression (log-rank, P < 0.001). Univariate and multivariate analyses indicated that vascular invasion (P = 0.012), lymphatic permeation (P = 0.038), and NDRG1 expression (P = 0.026) were independent prognostic factors. Expression of NDRG1 and positivity for c-Myc were significantly correlated (P = 0.005). These findings indicate that NDRG1 expression is associated with both prognosis and c-Myc expression in lung adenocarcinoma.

Abstract
AIMS The number of patients undergoing arthroscopic surgery of the hip has increased significantly during the past decade. It has now become an established technique for the treatment of many intra- and extra-articular conditions affecting the hip. However, it has a steep learning curve and is not without the risk of complications. The purpose of this systematic review was to determine the prevalence of complications during and following this procedure. MATERIALS AND METHODS Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in designing this study. Two reviewers systematically searched the literature for complications related to arthroscopy of the hip. The research question and eligibility criteria were established a priori. Pertinent data were abstracted and analysed. RESULTS We found 276 relevant studies with a total of 36 761 arthroscopies that met the inclusion criteria. The mean age of the patients was 36.7 years (1.7 to 70) and the mean body mass index was 25.7 kg/m2 (20.2 to 29.2). Femoroacetabular impingement and labral tears were the most common indications for the procedure. The total number of complications was 1222 (3.3%). Nerve injury (0.9%), mainly involving the pudendal and lateral femoral cutaneous nerves, and iatrogenic chondral and labral injury (0.7%), were the two most common complications. There were 58 major complications (0.2%), the most common being intra-abdominal extravasation of fluid, which was found in 13 cases (0.04%). There were three deaths (0.008%). CONCLUSION Arthroscopic surgery of the hip is a procedure with a relatively low rate of complications, although some may be significant in this young cohort of patients. This study relied on the reported complications only and the results should be interpreted with caution. Cite this article: Bone Joint J 2017;99-B:1577-83.

Abstract
Although several non-alcoholic steatohepatitis (NASH) models have been reported to date, few of these models fully reflect the histopathology and pathophysiology of human NASH. The aim of this study was to establish a novel NASH model by feeding a high-fat (HF) diet and administering both carbon tetrachloride (CCl4 ) and the Liver X receptor agonist T0901317. Male C57BL/6J mice were divided into four groups (each n = 5): HF, HF + CCl4 , HF + T0901317, and the novel NASH model (HF + CCl4 + T0901317). CCl4 (0.1 mL/kg) and T0901317 (2.5 mg/kg) were intraperitoneally administered four times and five times, respectively. The livers of the novel NASH model group presented a whitish colour. The serum levels of TNF-α and IL-6 were significantly increased in the novel NASH model group, and mice in this group exhibited histopathological features and insulin resistance reflective of NASH, i.e., macrovesicular hepatic steatosis, ballooning hepatocytes, Mallory-Denk bodies, lobular inflammation and fibrosis. The novel NASH model group presented significantly upregulated expression levels of mRNAs related to lipogenesis, oxidative stress, fibrosis and steatosis and significantly downregulated expression levels of mRNAs related to triglyceride export. We successfully established a novel experimental NASH model that exhibits similar histopathology and pathophysiology to human NASH.

Abstract
Cyclophilin A (CypA) has been reported to be upregulated in malignant tumors. CypA expression is thought to be associated with acquisition of tumor growth and anti-apoptotic function. Although upregulation of CypA has been reported in lung adenocarcinoma, its clinicopathological significance and roles in malignant progression remain unclear. Here we investigated the implications of CypA expression for outcome in patients with lung adenocarcinoma. Lung adenocarcinoma specimens from 198 cases were selected and reclassified according to the World Health Organization classification (4th edition) and the Noguchi classification. CypA expression was assessed by immunohistochemistry, and the H-score was calculated on the basis of intensity and proportion. The specificity of the antibody used was confirmed by Western blotting and the cut-off point was determined from the ROC curve. Sixty-seven cases (33.8%) had low CypA expression (CypA-L group) and 131 (66.2%) had high CypA expression (CypA-H group). Many cases of adenocarcinoma in situ were CypA-L, and advanced adenocarcinomas tended to be classified as CypA-H. Clinically, patients with CypA-H tumors showed a significantly poorer prognosis than those with CypA-L tumors. This is the first investigation of the implications of the CypA expression level in terms of the clinical characteristics of resected lung adenocarcinomas.

Abstract
Although the introduction of tyrosine kinase inhibitors (TKIs) has improved overall survival of patients with chronic myeloid leukemia (CML), about half of the patients eventually relapse after cessation of TKIs. In contrast, the remainder of the patients maintain molecular remission without TKIs, indicating that the patients' immune system could control proliferation of TKI-resistant leukemic stem cells (LSCs). However, the precise mechanism of immunity against CML-LSCs is not fully understood. We have identified a novel immune target, CXorf48, expressed in LSCs of CML patients. Cytotoxic T cells (CTLs) induced by the epitope peptide derived from CXorf48 recognized CD34+CD38- cells obtained from the bone marrow of CML patients. We detected CXorf48-specific CTLs in the peripheral blood mononuclear cells from CML patients who have discontinued imatinib after maintaining complete molecular remission for more than 2 years. Significantly, the relapse rate of CXorf48-specific CTL-negative patients was 63.6%, compared to 0% in CXorf48-specific CTL-positive patients. These results indicate that CXorf48 could be a promising therapeutic target of LSCs for immunotherapy to obtain durable treatment-free remission in CML patients.

Abstract
Background Hypergastrinemia and the resultant peptic ulcer related to an enteric duplication has been quite rarely reported in the literature. Case presentation We herein report the case of a 4-year-old girl who presented with hypergastrinemia and a duodenal ulcer at 2 years of age. She had been followed up with a proton pump inhibitor, which resulted in resolution of the ulcer; however, unexplained hypergastrinemia had continued. A cystic lesion at the antrum was discovered at 4 years of age, which we suspected to be a gastric duplication. After we resected the lesion, the hypergastrinemia resolved without recurrence of the duodenal ulcer. The histology was compatible with a gastric duplication, and the lumen was lined with antral mucosa that strongly stained positive for gastrin. We presumed that the antral mucosa inside the duplication in our case had no hydrogen ion feedback inhibition of gastrin release from gastrin cells and increased release of gastrin from the mucosa inside the duplication led to the duodenal ulcer. Only two cases have been reported in the literature that had hypergastrinemia related to enteric duplication. Conclusion Gastric duplication should be included in the differential diagnosis of sustained hypergastrinemia in children.

Early application of related SCT might improve clinical outcome in adult T-cell leukemia/lymphoma. Bone Marrow Transplant 2015; 51:205-11.

Abstract
Allogeneic hematopoietic SCT (allo-HSCT) is a curative treatment for aggressive adult T-cell leukemia/lymphoma (ATLL). Considering the dismal prognosis associated with conventional chemotherapies, early application of allo-HSCT might be beneficial for patients with ATLL. However, no previous study has addressed the optimal timing of allo-HSCT from related donors. Hence, to evaluate the impact of timing of allo-HSCT for patients with ATLL, we retrospectively analyzed data from patients with ATLL who received an allo-HSCT from a related donor. The median age was 52 years. Patients were grouped according to the interval from diagnosis to allo-HSCT: early transplant group, <100 days, n=72; late transplant group, ⩾100 days, n=428. The corresponding constituents of disease status were not statistically different between the two groups (P=0.11). The probability of OS in the early transplant group was significantly higher than that in the late transplant group (4-year OS, 49.3% vs 31.2%). Multivariate analysis revealed that late allo-HSCT was an unfavorable prognostic factor for OS (hazard ratio, 1.46; 95% confidence interval (CI), 1.01-2.11; P=0.04). Despite the limitations of a retrospective study, it might be acceptable to consider early application of allo-HSCT for ATLL.

A radiographic analysis of alignment of the lower extremities--initiation and progression of varus-type knee osteoarthritis. Osteoarthritis Cartilage 2015; 23:217-23.

Abstract
OBJECTIVE This study aimed to investigate alignment based on age in normal knees and alignment based on deformity in osteoarthritis (OA) knees using detailed radiographic parameters. DESIGN Various parameters were measured from weight-bearing long leg radiographs of 1251 legs (797 normal and 454 OA knees) as a cross-sectional study. Normal knees were classified by age (young, middle aged, aged, and elderly) and symptomatic OA knees on the basis of the alignment (femorotibial angle (FTA): mild, moderate, severe and profound). The mean measurements in each group were calculated and compared within each group. RESULTS The femoral shaft showed medially bowed curvature (femoral bowing) of approximately 2° in the young normal group, which shifted to lateral bowing with age. However, OA knees showed larger lateral bowing with OA grade, which might reduce the condylar-shaft angle and subsequently shifted the mechanical axis medially. Progression of mild to moderate OA might be associated with a decreasing condylar-shaft angle (femoral condylar orientation) and widening condylar-plateau angle (joint space narrowing) rather than decreasing tibial plateau flattering. Steeping of the tibial plateau inclination due to increasing tibial plateau shift (tibial plateau compression) rather than medial tibial bowing might be the main contributor to worsening of varus deformity in knees with severe and profound OA. CONCLUSIONS This cross-sectional study might provide the possibility of OA initiation and progression. The lateral curvature of the femoral shaft associated with aging may contribute to the initiation of varus-type OA of the knee. These changes in the femur may be followed by secondary signs of OA progression including varus femoral condylar orientation, medial joint space narrowing, and tibial plateau compression.

A 45-year-old man presented with severe abdominal distention with massive ascites due to a diffusely disseminated peritoneal tumor. A core needle biopsy specimen was obtained from the peritoneal lesion. Histological diagnosis was epithelioid type mesothelioma. He did not choose to receive chemotherapy. For 2.5 years, he went without medical intervention, and his disease gradually progressed, leading to a worsening of his symptoms. The patient then chose to be treated with combination chemotherapy of cisplatin and pemetrexed, followed by pemetrexed alone. There was remarkable tumor shrinkage and his symptoms improved. These effects have been sustained for two years after the initial chemotherapy. Chemotherapy appears to have contributed to survival prolongation for this patient. This case exemplifies the fact that malignant peritoneal mesothelioma may progress slowly when fits with some good prognostic factors, and it is important to consider the prognostic factors.

Abstract
A 33-year-old homosexual Japanese man who admitted to having sex with men presented with a two-week history of dyspnea and fever. Chest imaging showed diffuse pulmonary frosted-glass-like shadows. A blood test revealed positive HIV antibodies with a CD4 cell count of 66/μL. Bronchoalveolar lavage identified pneumocystis. Although the patient exhibited a transient response to anti-pneumocystis treatment and mega-dose steroid pulse therapy, he eventually died from respiratory failure. An autopsy suggested massive cytomegalovirus and pneumocystis pneumonitis. The pulmonary co-infection with cytomegalovirus may have been worsened by the use of mega-dose steroids, and such therapy should be avoided in patients with a high HIV viral load and low CD4 count.

Abstract
BACKGROUND ATP2A2 encoding the sarcoplasmic/endoplasmic reticulum Ca(2+) -ATPase2 (SERCA2) is a Darier disease (DD)-related gene. Ultraviolet (UV) B irradiation downregulates ATP2A2/SERCA2 expression in keratinocytes, whereas cyclooxygenase-2 (COX-2) expression is dramatically upregulated by UVB. OBJECTIVES To analyse the involvement of COX-2 in ATP2A2/SERCA2 expression. METHODS Keratinocytes were transfected with COX-2 siRNA or treated with COX-2 inhibitor, celecoxib, to evaluate the effect of COX-2 on ATP2A2/SERCA2 expression. Quantitative real-time polymerase chain reaction, Western blotting analysis and reporter assay were used to determine the amount of mRNA, protein level and transcription activity, respectively. RESULTS COX-2 knockdown by siRNA resulted in upregulation of ATP2A2 transcription. Treatment by celecoxib rescued UVB-mediated suppression of the ATP2A2 transcription and SERCA2 protein expression. Simple addition of prostaglandin (PG) E(2) , which is a product of COX-2 enzyme, reduced the amounts of ATP2A2 mRNA and SERCA2 protein in keratinocytes. CONCLUSIONS UVB downregulates ATP2A2/SERCA2 expression via induction of COX-2 expression and subsequent increase of PGE(2) production in keratinocytes. Considering that DD is caused by the decreased function of SERCA2 due to the reduced expression of the ATP2A2 gene, this finding shows the possibility that COX-2 inhibition may be useful to prevent and/or treat DD.

Abstract
BACKGROUND Pneumonia caused by Stenotrophomonas maltophilia is rare, but can be lethal in severely immunocompromised patients. However, its clinical course remains unclear. PATIENTS AND METHODS Patients with pneumonia caused by S. maltophilia in Toranomon Hospital (890 beds, Tokyo, Japan) were reviewed retrospectively between April 2006 and March 2010. RESULTS During the study period, 10 cases of S. maltophilia pneumonia were identified. Seven patients had acute myeloid leukemia, 2 had myelodysplastic syndrome, and 1 had malignant lymphoma. All patients developed symptoms after allogeneic hematopoietic stem cell transplantation (HSCT). Five patients received first cord blood transplantation (CBT), 4 patients received second CBT, and 1 patient received first peripheral blood stem cell transplantation (PBSCT). The overall incidence of S. maltophilia pneumonia among 508 patients who received HSCT during the period was 2.0%. The incidence was 0% (0/95) in patients after bone marrow transplantation, 0.8% (1/133) after PBSCT, and 3.2% (9/279) after CBT. Pneumonia developed a median of 13.5 days (range, 6-40) after transplantation. At onset, the median white blood cell count was 10/μL (range, 10-1900), and the median neutrophil count was 0/μL (range, 0-1720). In all patients, S. maltophilia bacteremia developed with bloody sputum or hemoptysis. The 28-day mortality rate was 100%; the median survival after onset of pneumonia was 2 days (range, 1-10). CONCLUSIONS Hemorrhagic S. maltophilia pneumonia rapidly progresses and is fatal in patients with hematologic malignancy. Attention should be particularly paid to the neutropenic phase early after HSCT or prolonged neutropenia due to engraftment failure. A prompt trimethoprim-sulfamethoxazole-based multidrug combination regimen should be considered to rescue suspected cases of S. maltophilia pneumonia in these severely immunosuppressed patients.

Abstract
Mycobacterial infection of musculoskeletal tissue is a rare disease that may cause destruction of the tissues. Both Mycobacterium tuberculosis and non-tuberculous mycobacteria affect the tissues. Although surgical debridement and antibiotic therapy are required for the treatment, it is necessary to identify the causative species before selecting the antibiotics. However, it is difficult to identify the species in clinical samples from musculoskeletal tissue. In the current study, using pathological specimens, the causative species was identified by PCR amplification and direct sequencing of mycobacterial 16S rDNA containing a hypervariable region. Twelve cases of chronic granulomatous inflammation of musculoskeletal tissues were used for the study. DNA was extracted from paraffin sections, and mycobacterial 16S rDNA was amplified by PCR. The amplicons were obtained in 5 of 12 cases (41%), even in specimens in which the microorganism was only scarcely detected by using special stains. Direct sequencing of the amplified products presented high homology with M. tuberculosis in four cases and M. avium in one. Therefore, PCR-direct sequencing of 16S rDNA containing hypervariable region using pathological specimens is useful for the diagnosis and identification of causative species in mycobacterial infection of musculoskeletal tissues.

Abstract
Early changes of Runx2 and Msx2 expressions were examined by immunohistochemistry in mouse periodontal ligament exposed to mechanical stress. 8-week-old ddY mouse was used as experimental animal. To provide a continuous mechanical stress on periodontal ligament, rubber dam sheet was placed between upper molars of the mouse. At 20 minutes, 1 hour, 3 hours, 9 hours and 24 hours after insertion of the sheet, relevant parts of the mouse tissues were excised and fixed in 4% paraformaldehyde/0.05M phosphate buffered fixative solution. Then serial paraffin sections were prepared and histopathological evaluation as well as examination of Runx2, Msx2 and alkaline phosphatase (ALP) expressions by immunohistochemistry were performed. Control animals were not subjected to mechanical stress. In the experimental group, strong expressions of Runx2 and Msx2 were seen in periodontal fibroblasts of the tension side at 20 minutes after mechanical stress. Expressions of Runx2 and Msx2 became stronger in parallel with time, and at 24 hours after mechanical stress, the periodontal fibroblasts, cementoblasts as well as osteoblasts showed strong expression. Moreover, ALP has also demonstrated similar strong expression. On the other hand, in the control group, although expressions of Runx2, Msx2 and ALP were detected at all the experiment times, the expressions were weak. All these results strongly suggested that Runx2 promoted differentiation of osteoblasts at early stage and Msx2 worked as an activator of Runx2 function.

Abstract
BACKGROUND CDK5 is a member of proline-directed serine/threonine kinases. Although its cDNA was originally cloned as a homologue to those for the other members of the cyclin-dependent kinase (CDK) family, CDK5 has been shown to function differently from other CDKs. CDK5 is activated by non-cyclin partners, p35 and p39, and important during brain development by influencing adhesion, migration and differentiation of neurones. OBJECTIVES We sought to investigate the expression and functions of CDK5 in human keratinocytes. METHODS Expression of CDK5/p35, interaction of CDK5/p35 with adhesion molecules, and its roles in cell-cell and cell-matrix adhesion were studied by reverse transcriptase-polymerase chain reaction, immunoblotting and aggregation/adhesion assays in primary cultured normal human keratinocytes from infant foreskins and a human keratinocyte HaCaT cell line. Localization of CDK5 and p35 in normal human epidermis and psoriatic epidermis was studied by immunohistochemistry. RESULTS Both CDK5 and p35 were expressed in primary cultured keratinocytes, HaCaT cells and normal human epidermis. Roscovitine, an inhibitor of CDK5, enhanced Ca2+-dependent (cadherin-dependent) aggregation of HaCaT cells whereas it inhibited adhesion of HaCaT cells to fibronectin associated with reduced active states of beta1 integrin. Interestingly, psoriatic skin showed reduced CDK5 and p35 expression in the lower half of the epidermis, which might be associated with decreased amount of activated beta1 integrin in the epidermis of psoriatic skin. CONCLUSIONS CDK5/p35 may be involved in cell-cell and cell-matrix adhesion in human keratinocytes by differently regulating cadherins and integrins. Furthermore, reduced expression of CDK5/p35 in the epidermis might be involved in the pathogenesis of psoriasis.

Abstract
This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.
