2Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13
3Effects of mindfulness-based intervention programs on sleep among people with common mental disorders:A systematic review and meta-analysis显示文摘BACKGROUND Sleep problems are particularly prevalent in people with depression or anxiety disorder.Although mindfulness has been suggested as an important component in alleviating insomnia,no comprehensive review and meta-analysis has been conducted to evaluate the effects of different mindfulness-based intervention(MBI)programs on sleep among people with depression or anxiety disorder.AIM To compare the effects of different MBI programs on sleep among people with depression or anxiety disorder.METHODS Related publications in Embase,Medline,PubMed and PsycINFO databases were systematically searched from January 2010 to June 2020 for randomised controlled trials.Data were synthesized using a random-effects or a fixed-effects model to analyse the effects of various MBI programs on sleep problems among people with depression or anxiety disorder.The fixed-effects model was used when heterogeneity was negligible,and the random-effects model was used when heterogeneity was significant to calculate the standardised mean differences(SMDs)and 95%confidence intervals(CIs).RESULTS We identified 397 articles,of which 10 randomised controlled trials,involving a total of 541 participants,were included in the meta-analysis.Studies of internet mindfulness meditation intervention(IMMI),mindfulness meditation(MM),mindfulness-based cognitive therapy(MBCT),mindfulness-based stress reduction(MBSR)and mindfulness-based touch therapy(MBTT)met the inclusion criteria.The greatest effect sizes are reported in favour of MBTT,with SMDs of-1.138(95%CI:-1.937 to-0.340;P=0.005),followed by-1.003(95%CI:-1.645 to-0.360;P=0.002)for MBCT.SMDs of-0.618(95%CI:-0.980 to-0.257;P=0.001)and-0.551(95%CI:-0.842 to-0.260;P<0.0001)were reported for IMMI and MBSR in the pooling trials,respectively.Significant effects on sleep problem improvement are shown in all reviewed MBI programs,except MM,for which the effect size was shown to be nonsignificant.CONCLUSION All MBI programs(MBTT,MBCT,IMMI and MBSR),except MM,are effective options to improve sleep problems among people with depression or anxiety disorder.Sunny Ho-Wan Chan Danielle Lui Hazel Chan Kelly Sum Ava Cheung Hayley Yip Chong Ho Yu 2022World Journal of Psychiatry2022,12,4:5
4Adrenal G protein-coupled receptor kinase-2 in regulation of sympathetic nervous system activity in heart failure显示文摘Heart failure(HF), the number one cause of death in the western world, is caused by the insufficient performance of the heart leading to tissue underperfusion in response to an injury or insult. It comprises complex interactions between important neurohormonal mechanisms that try but ultimately fail to sustain cardiac output. The most prominent such mechanism is the sympathetic(adrenergic) nervous system(SNS), whose activity and outflow are greatly elevated in HF. SNS hyperactivity confers significant toxicity to the failing heart and markedly increases HF morbidity and mortality via excessive activation of adrenergic receptors, which are G protein-coupled receptors. Thus, ligand binding induces their coupling to heterotrimeric G proteins that transduce intracellular signals. G protein signaling is turned-off by the agonist-bound receptor phosphorylation courtesy of G protein-coupled receptor kinases(GRKs), followed by βarrestin binding, which prevents the GRK-phosphorylated receptor from further interaction with the G proteins and simultaneously leads it inside the cell(receptor sequestration). Recent evidence indicates that adrenal GRK2 and βarrestins can regulate adrenal catecholamine secretion, thereby modulating SNS activity in HF. The present review gives an account of all these studies on adrenal GRKs and βarrestins in HF and discusses the exciting new therapeutic possibilities for chronic HF offered by targeting these proteins pharmacologically.Katie A Mc Crink Ava Brill Anastasios Lymperopoulos 2015World Journal of Cardiology2015,7,9:4
5Survival analysis of breast cancer liver metastasis treated by hepatectomy: A propensity score analysis for Chinese women in Hong Kong显示文摘Background: Survival of patients with breast cancer liver metastasis is very poor. This study aimed to analyze the survival outcome of hepatectomy for this patient population. Methods: From January 1995 to December 2014, 2522 patients with liver cancer received hepatectomy at our hospital. Twenty-one of them, all female, received the operation for breast cancer liver metastasis. Performance was compared with patients with colorectal liver metastasis treated with hepatectomy after propensity score analysis in a ratio of 1:3. Results: Twenty-one patients received hepatectomy for breast cancer. After propensity score matching, 63 patients who had hepatectomy for colorectal cancer were selected for comparison. There was no significant difference in immediate or short-term outcomes between the two groups of patients in terms of operative time, blood loss and surgical morbidities. All patients with breast cancer had R0 resection. No hospital death occurred. After hepatectomy, the 1-, 3- and 5-year overall survival rates were 100.0%, 58.9% and 58.9% respectively in patients with breast cancer. The 1-, 3- and 5-year overall survival rates were 95.0%, 57.2% and 39.7% respectively in patients with colorectal cancer (P = 0.572). On multivariate analysis, triple negative status was the only independent poor prognostic factor in breast cancer liver metastasis (OR = 6.411;95% CI: 1.351–30.435;P = 0.019). Conclusions: Hepatectomy is a safe and effective way of treating breast cancer liver metastasis at experienced centers where multidisciplinary adjuvant treatments are available. It can be considered more frequently as part of the multidisciplinary care for this patient population.Tan To Cheung Kenneth SH Chok Albert CY Chan Simon HY Tsang Wing Chiu Dai Thomas CC Yau Ava Kwong Chung Mau Lo 2019Hepatobiliary & Pancreatic Diseases International2019,18,5:3
6Pathways of fear and anxiety in dentistry: A review显示文摘The aim of this article was to analyze the theories underpinning dental fear, anxiety and phobias. To be included, articles must have been published between the years of 1949 and 2013 concerning fears and phobias within dentistry and/or psychiatry. Of 200 articles originally under review, 140 were included and reviewed by the authors.Five specific pathways relating to dental fear and anxiety were identified; Cognitive Conditioning, Informative, Visual Vicarious, Verbal Threat, and Parental. Eight currently accepted management techniques across all dental disciplines for dental fear and anxiety were identified. Further research is required to identify clinical diagnosis and treatment for fears originating from different pathways.Ava Elizabeth Carter Geoff Carter Mark Boschen Emad AlShwaimi Roy George 2014World Journal of Clinical Cases2014,2,11:3

8Graphene quantum dots rescue protein dysregulation of pancreatic β-cells exposed to human islet amyloid polypeptide显示文摘The amyloid aggregation of peptides and proteins is a hallmark of neurological disorders and type 2 diabetes.Human islet amyloid polypeptide(IAPP),co-secreted with insulin by pancreaticβ-cells,plays dual roles in both glycemic control and the pathology of type 2 diabetes.While IAPP can activate the NLRP3 inflammasome and modulate cellular autophagy,apoptosis and extracellular matrix metabolism,no data is available concerning intracellular protein expression upon exposure to the polypeptide.More surprisingly,how intracellular protein expression is modulated by nanoparticle inhibitors of protein aggregation remains entirely unknown.In this study,we first examined the changing proteomes ofβTC6,a pancreaticβ-cell line,upon exposure to monomeric,oligomeric and fibrillar IAPP,and detailed cellular protein expression rescued by graphene quantum dots(GQDs),an IAPP inhibitor.We found that 29 proteins were significantly dysregulated by the IAPP species,while majority of these proteins were nucleotide-binding proteins.Collectively,our liquid chromatography tandem-mass spectrometry,fluorescence quenching,helium ion microscopy,cytotoxicity and discreet molecular dynamics simulations data revealed a remarkable capacity of GQDs in regulating aberrant protein expression through H-bonding and hydrophobic interactions,pointing to nanomedicine as a new frontier against human amyloid diseases.Ava Faridi Yunxiang Sun Monika Mortimer Ritchlynn R.Aranha Aparna Nandakumar Yuhuan Li Ibrahim Javed Aleksandr Kakinen Qingqing Fan Anthony W.Purcell Thomas P.Davis Feng Ding Pouya Faridi Pu Chun Ke 2019Nano Research2019,12,11:2
