- Abstract
Introduction: Allogeneic hematopoietic cell transplantation (alloHCT) is increasingly offered to older adults, and its potential impact on cognition in this population is understudied. This work aims to evaluate the ability of cancer-specific geriatric assessments (cGA) and a global frailty index based on accumulation of deficits identified in the cGA to predict the risk of cognitive decline after alloHCT in older adults., Materials and Methods: AlloHCT recipients aged 50 years or older completed a cGA, including a cognitive evaluation by the Blessed Orientation Memory Concentration (BOMC) test, at baseline prior to alloHCT and then at 3, 6, and 12 months after transplant. Baseline frailty was assessed using a deficit accumulation frailty index (DAFI) calculated from the cGA. A multinomial logit model was used to examine the association between predictors (individual cGA measures, DAFI) and the following three outcomes: alive with stable or improved cognition, alive with cognitive decline, and deceased. In post-hoc analyses, analysis of variance was used to compare BOMC scores at baseline, 3, 6, and 12 months across frailty categories., Results: In total, 148 participants were included, with a median age of 62 (range 50-76). At baseline, 12% had cognitive impairment; at one year, 29% of survivors had improved BOMC scores, 33% had stable BOMC, and 37% had worse BOMC. Prior to transplant, 25% were pre-frail and 11% were frail. Individual baseline cGA measures were not associated with cognitive change at one year as assessed by BOMC. Adjusting for age, sex, and education, those who were frail at baseline were 7.4 times as likely to develop cognitive decline at one year than those who were non-frail, although this finding did not reach statistical significance (95% confidence interval [CI] 0.74-73.8, p = 0.09). The probability of being alive with stable/improved cognition at 12 months for the non-frail, pre-frail, and frail groups was 43%, 34%, and 8%, respectively., Discussion: Baseline geriatric measures and frailty were not significantly associated with cognitive change as assessed by BOMC in adults aged 50 or older after alloHCT. However, the study was underpowered to detect clinically meaningful differences, and future work to elucidate potential associations between frailty and cognitive outcomes is warranted., Competing Interests: Declaration of Competing Interest Dr. Olin reports other from Cellectis, personal fees from Actinium, personal fees from Astellas, personal fees from Abbvie, outside the submitted work., (Published by Elsevier Ltd.)

- Abstract
Non-Hodgkin lymphoma (NHL) is a disease of older adults, with a median age at diagnosis of 67 years. Treatment in older adults with NHL is challenging. The aging process is associated with a decline in functional reserve that varies among individuals, and results in an increasing risk of treatment-related toxicity and mortality. Chronological age and performance status fail to capture the multidimensional and heterogeneous nature of the aging process. A geriatric assessment (GA) screens multiple geriatric domains and provides a more accurate assessment of functional reserve. Several abbreviated GA tools have been developed for use in oncology clinics and help identify patients at high risk for chemotherapy-related toxicity and mortality. In this review, we explore GA tools validated for use in patients with NHL. We discuss the evidence behind GA-guided treatment in NHL and present a suggested approach to assessing frailty in this patient population., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

- Abstract
Osteoarthritis (OA) is characterized with articular cartilage degradation, and monosodium iodoacetate (MIA)-treated chondrocyte is the most commonly used model for mimicking OA progression. Zinc protects chondrocytes from MIA-induced damage. Here, we explored the protective effects of 25 μM zinc on 5 μM MIA-treated SW1353 cells (human chondrosarcoma cell line) through the analysis of energy metabolism- and autophagy-related parameters. We found that the exposure of SW1353 cells to MIA decreased ATP levels, expression of glycolysis-related proteins, including glucose transporter 1, hexokinase 2, and pyruvate dehydrogenase E1 component subunit alpha, and the levels of mitochondrial complex I, II, IV, and V subunits of the oxidative phosphorylation pathway. MIA treatment also decreased the expression of autophagy-related proteins, including autophagic elongation protein 5 (ATG5), ATG7, and microtubule-associated protein 1A/1B light chain 3B (LC3-II) and mitophagy-related proteins, including phosphatase and tensin homolog (PTEN)-induced putative kinase 1 (PINK1), ubiquitin, and p62. These results indicate that MIA interferes with energy metabolism and the autophagic clearance of dysfunctional mitochondria (so called mitophagy). Interestingly, zinc exposure could almost completely reverse the effects of MIA, suggesting its potential protective role against OA progression., (Copyright © 2019 Elsevier Inc.

- Abstract
Background and Aim: Fibrosis index based on the four factors (FIB-4) and aspartate aminotransferase to platelet ratio index (APRI) were not well validated in patients with chronic hepatitis B (CHB). The aim of this study was to validate the performances of these indexes and construct novel indexes for liver fibrosis assessment., Methods: A total of 1438 consecutive antivirus treatment-naïve patients with CHB were analysed, and two novel indexes (named HeBCI and HeBFI) were derived for cirrhosis and significant fibrosis detection., Results: For cirrhosis, the area under receiver operating characteristic curves (AUROCs) were 0.841 for HeBCI, 0.708 for FIB-4 and 0.623 for APRI in the model set, and 0.779, 0.690, 0.595 in the validation set. For significant fibrosis, the AUROCs were 0.781 for HeBFI, 0.693 for APRI and 0.641 for FIB-4 in the model set, and 0.776, 0.729, 0.641 in the validation set. HeBCI determined 750 (52.2%) patients as having cirrhosis or non-cirrhosis with an accuracy of 86%. HeBFI detected 673 (46.8%) patients with or without significant fibrosis with an accuracy of 76.6%., Conclusions: As economical and convenient indexes, HeBCI and HeBFI are suitable to serve as outpatient tools for detecting significant fibrosis and cirrhosis to reduce the need of liver biopsy significantly in resource-limited settings., (Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l.

- Abstract
Treatment for the older adult with acute myeloid leukemia (AML) is challenging, due to both more aggressive disease biology as well as patient-related risk factors that limit tolerance of intensive chemotherapy. The use of prognostic models and comprehensive geriatric assessments can help hematologists evaluate the suitability of intensive chemotherapy for individual patients. For older patients considered fit for intensive chemotherapy, standard induction therapy should be given, followed by consideration of reduced intensity allogeneic stem cell transplantation. Patients considered unfit for intensive therapy are standardly treated with hypomethylating agents. Several new therapeutic agents have shown promising results either by improving intensive chemotherapy (CPX-351), by improving upon lower intensity therapy (venetoclax, antibody drug conjugates), or by targeting somatic mutations (FLT3 inhibitors and others)., (Copyright © 2017 Elsevier Inc.

- Abstract
Arsenic trioxide is used to treat a variety of leukaemia types and causes tumour cell death. However, it is not well known whether arsenic trioxide is toxic to bone osteoblast cells, the precursor cells from which leukaemia cells originate. The aim of this study was to examine the response of osteosarcoma cell line MG63 and primary cultured osteoblasts to arsenic trioxide treatment. After 24h of treatment, arsenic trioxide was more effective at inhibiting cell growth and increasing oxidative stress and DNA damage in MG63 cells than in osteoblasts. In addition, arsenic trioxide arrested cell cycle progression in the G2/M phase, and induced apoptosis in MG63 cells, but not in primary cultured osteoblasts. The results further showed that the expression of transcription factor Nrf2 and its downstream antioxidant effectors, including hemeoxygenase-1, glutathione, and superoxide dismutase, was increased in primary cultured osteoblasts. Additionally, expression of heat shock proteins was also increased. Experiments using inhibitors of antioxidant enzymes in the presence of arsenic trioxide-treated osteoblasts demonstrated that glutathione and superoxide dismutase were responsible for reducing oxidative stress, caspase-3 activity, and apoptosis and that heat shock proteins helped reduce caspase-3 activity. Unexpectedly, there was no apparent effect of the markedly increased hemeoxygenase-1, suggesting that other functions might exist for hemeoxygenase-1. These findings demonstrate that osteosarcoma cells are more sensitive to arsenic trioxide treatment than primary cultured osteoblasts and that primary cultured osteoblasts activate the Nrf2 signalling pathway in response to arsenic trioxide exposure to escape from oxidative damage and apoptosis., (Copyright © 2016 Elsevier Ltd.

- Abstract
Background: Arecoline, the most abundant areca alkaloid, has been reported to stimulate reactive oxygen species (ROS) production in several cell types. Overproduction of ROS has been implicated in atherogenesis. Hemeoxygenase-1 (HO-1) has cytoprotective activities in vascular tissues. This study investigated the effect of arecoline on adhesion molecule expression and explored the role of HO-1 in this process., Methods: Human umbilical vein endothelial cells (HUVECs) were treated with arecoline, then ROS levels and the expression of adhesion molecules and HO-1 were analyzed and potential signaling pathways investigated., Results: After 2h of arecoline treatment, ROS production was stimulated and reached a maximum at 12h. Expression of the adhesion molecules ICAM and VCAM was also induced. Glutathione pretreatment completely blocked arecoline-stimulated ROS production and VCAM expression, but not ICAM expression. Arecoline also induced HO-1 expression and this effect was partly due by ROS stimulation. Inhibition of c-jun N-terminal kinase (JNK) by SP600125, p38 by SB 203580, or tyrosine kinase by genistein reduced arecoline-induced HO-1 expression. In contrast, inhibition of ERK (extracellular signal-related MAP kinase) by PD98059 had no effect. Transfection of HUVECs with the GFP/HO-1 gene, which resulted in a 5-fold increase in HO-1 activity, markedly, but not completely, inhibited the decrease in cell viability caused by arecoline., Conclusions: This study demonstrates that, in HUVECs, arecoline stimulates ROS production and ICAM and VCAM expression. HO-1 expression is also upregulated through the ROS, tyrosine kinase, and MAPK (JNK and p38) signaling pathways., (Crown Copyright © 2010. Published by Elsevier Ireland Ltd. All rights reserved.)

- Abstract
Objective: Torsion of adnexa is relatively common, but isolated torsion of the fallopian tube is rare. It should be considered in all adolescents who present with acute pelvic pain. Laparoscopy or laparotomy is often necessary to establish the diagnosis. This report focuses on a 14-year-old girl with isolated tubal torsion who presented with acute pelvic pain., Case Report: A 14-year-old adolescent was admitted to our hospital because of acute right-sided abdominal pain without vomiting and diarrhea. Pelvic ultrasound showed an adnexal mass. Conservative treatment was given but did not improve her condition. Emergent laparoscopy was performed due to persistent symptoms, which later confirmed the diagnosis of isolated torsion of the fallopian tube. Pathology showed hemosalpinx with necrosis., Conclusion: Isolated torsion of the fallopian tube is an uncommon event, especially in adolescents. It must be kept in mind whenever a young girl presents with low abdominal pain and pelvic mass on ultrasound. Prompt laparoscopic intervention may allow for early diagnosis, treatment and preservation of the tube if possible.

- Abstract
Background: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis., Methods: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, analyzed, and compared with those of 3254 PLC patients before the 30 years., Results: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resection rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6% respectively in contrast to 0.4%, 47.0%, and 52.6% reported before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage patients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively., Conclusion: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed early. More PLC patients tend to undergo resection while receiving a better conservative treatment, which ensures a prognosis.
