Abstract
A 60-year-old woman presented with a history of "pathological myopia combined with macular hole retinal detachment, " for which she underwent vitrectomy, internal limiting membrane tamponade, and silicone oil filling surgery one year ago. Seven months ago, the silicone oil was removed. She now returned to seek medical attention as her visual acuity has declined by 10 diopters. Examination revealed a recurrence of macular hole retinal detachment. The patient was treated with combined amniotic membrane tamponade and silicone oil filling. During the surgery, the frozen amniotic membrane was cut into 2 mm × 2 mm and placed under the macular hole retina after silicone oil filling. Within 6 months after the surgery, her retina repositioned well, the macular hole closed, and her visual function improved from hand motion to 0.05. No severe complications were observed. Therefore, this surgical approach provides a new perspective for treating recurrent pathological myopia combined with macular hole retinal detachment.

Abstract
OBJECTIVES The aim of this study was to evaluate the impact of a shared-care model on outcomes in patients with left ventricular assist devices (LVADs) living in remote locations. BACKGROUND Health care delivery through shared-care models has been shown to improve outcomes in patients with chronic diseases. However, the impact of shared-care models on outcomes in patients with LVAD is unknown. METHODS LVAD recipients in the authors' program (2007 to 2018) were classified based on the levels of care provided and training and resources used: level 1, was defined as outpatient primary care without LVAD-specific care; level 2 was level 1 services and outpatient LVAD-specific care; level 3 was level 2 services and inpatient LVAD-specific care and implantation center (IC). The Kaplan-Meier method was used to compare rates of survival, bleeding, pump thrombosis, infection, neurologic events, and readmissions among levels of care. RESULTS A total of 336 patients were included, with 255 patients (75.9%) cared for in shared-care facilities. Median follow-up was 810 (interquartile range: 321 to 1,096) days. In comparison to patients cared for by IC, patients at levels 2 and 3 shared-care centers had similar rates of death, bleeding, neurologic events, pump thromboses, and infections. However, the rates of death, pump thromboses, and infections were higher for level 1 patients than in IC patients. CONCLUSIONS Shared health care is an effective strategy to deliver care to patients with LVAD living in remote locations. However, patients in shared-care facilities unable to provide LVAD-specific care are at higher risk of unfavorable outcomes. Availability of LVAD-specific care should be strongly considered during patient selection and every effort made to ensure LVAD-specific training and resources are available at shared-care facilities.

Abstract
Neurodevelopmental and neurodegenerative diseases (NDDs) with severe neurological/psychiatric symptoms, such as cerebrovascular pathology in AD, CAA, and chronic stroke, have brought greater attention with their incidence and prevalence having markedly increased over the past few years. Causes of the significant neuropathologies, especially those observed in neurological diseases in the CNS, are commonly believed to involve multiple factors such as an age, a total environment, genetics, and an immunity contributing to their progression, neuronal, and vascular injuries. We primarily focused on the studies of glial involvement/dysfunction in part with the blood-brain barrier (BBB) and the neurovascular unit (NVU) changes, and the vascular mechanisms, which have been both suggested as critical roles in chronic stroke and many other NDDs. It has been noted that glial cells including astrocytes (which outnumber other cell types in the CNS) essentially contribute more to the BBB integrity, extracellular homeostasis, neurotransmitter release, regulation of neurogenic niches in response to neuroinflammatory stimulus, and synaptic plasticity. In a recent study for NDDs utilizing cellular and molecular biology and genetic and pharmacological tools, the role of reactive astrocytes (RACs) and gliosis was demonstrated, able to trigger pathophysiological/psychopathological detrimental changes during the disease progression. We speculate, in particular, the BBB, the NVU, and changes of the astrocytes (potentially different populations from the RACs) not only interfere with neuronal development and synaptogenesis, but also generate oxidative damages, contribute to beta-amyloid clearances and disrupted vasculature, as well as lead to neuroinflammatory disorders. During the past several decades, stem cell therapy has been investigated with a research focus to target related neuro-/vascular pathologies (cell replacement and repair) and neurological/psychiatric symptoms (paracrine protection and homeostasis). Evidence shows that transplantation of neurogenic or vasculogenic cells could be achieved to pursue differentiation and maturation within the diseased brains as expected. It would be hoped that, via regulating functions of astrocytes, astrocytic involvement, and modulation of the BBB, the NVU and astrocytes should be among major targets for therapeutics against NDDs pathogenesis by drug and cell-based therapies. The non-invasive strategies in combination with stem cell transplantation such as the well-tested intranasal deliveries for drug and stem cells by our and many other groups show great translational potentials in NDDs. Neuroimaging and clinically relevant analyzing tools need to be evaluated in various NDDs brains.

Abstract
Abstract
Background
Occasionally new onset cardiomyopathy patients (pts) present late and with such advanced disease stage that they cannot tolerate heart failure (HF) drug therapy. We sought to investigate the cardiac recovery (CR) potential following a combination of left ventricular assist device (LVAD) and guideline-directed HF drug therapy in this medication-naive population.
Methods
Chronic advanced HF requiring durable continuous-flow LVAD were prospectively evaluated. Patients with acute HF (myocarditis etc.) or post LVAD follow up <3 months were excluded. The “meds-treated” group (n=203) comprised patients treated adequately with at least one neurohormonal blocking agent during their HF history (b-blocker, ACEI/ARB, Aldosterone antagonist) and “meds-naive” group (n=8) comprised patients who were never before treated adequately with any HF medication. Baseline and follow up clinical, hemodynamic, imaging and laboratory data were analyzed. LVAD patients were phenotyped as CR responders or non responders, based on published predefined criteria.
Results
Univariate analysis showed that “med-naive” patients were younger, more likely to be on intravenous vasoactive agents, temporary mechanical support and with lower INTERMACS profile before LVAD implantation. Interestingly, no differences were seen in HF symptoms duration or other comorbidities. Baseline and follow up hemodynamics were similar in both groups, besides higher right atrial pressure pre-LVAD in the “meds-naive” group (16 vs 11 mmHg; p=0.04). Baseline echocardiographic (including LV dilation) and biochemical parameters revealed no differences between the groups, besides lower LVEF and higher BNP in the “meds-naive” group (14 vs 19%; p=0.03 and 2352 vs 1270; p=0.03, respectively). CR rates were significantly higher on “meds-naive” versus “meds-failed” group (50.0 vs 13.8%; p=0.005). Despite higher cardiac recovery rates in the “meds-naive” group the time course and magnitude of the favorable functional and structural response was similar among the CR responders of each of the 2 groups.
Conclusion
Young patients with new onset dilated cardiomyopathy sometimes present late, with advanced disease stage, unable to tolerate HF medications and requiring durable LVAD support. This patient population appears to have a potential for CR up to 50% and this could be factored in decisions surrounding their long-term therapeutic options.

Abstract
Abstract
Background
Predicting cardiac recovery (CR) in advanced heart failure (HF) patients before left ventricular assist device (LVAD) implantation remains challenging. This study sought to investigate whether CR after LVAD unloading can be predicted by cardiac functional and structural parameters together with clinical characteristics.
Methods
From 2008 to 2016, consecutive advanced chronic HF patients (N=347) supported with durable continuous-flow LVADs were prospectively evaluated. Patients with acute HF etiologies or without adequate post-LVAD follow up (<3 months) were excluded. A great variety of clinical characteristics were evaluated in the remaining 285 subjects. LVAD patients were phenotyped while on support, as CR Responders or Non Responders, based on published predefined echocardiographic criteria. Multivariable logistic regression was used to form the model and the Utah Cardiac Recovery (UCAR) score was created from the regression beta coefficients of the final model.
Results
CR occurred in 13.7% of patients. Univariate analysis showed that responders were more likely to be young, female, non-ischemic cardiomyopathy, with shorter HF symptoms duration and no prior cardiac surgery. They had lower blood urea nitrogen and were more likely to be on temporary mechanical support before LVAD. The multivariable UCAR model (AUC=0.755; p<0.001) predicted CR using 3 clinical parameters – Figure.
Conclusion
Univariate and multivariable predictors of CR include both modifiable and non-modifiable patient characteristics that are known prior to LVAD implantation. The UCAR score can serve as a practical tool for targeted patient selection to implement protocols that facilitate CR in the advanced HF patient subpopulation that is most likely to respond.

Abstract
BACKGROUND Gastrointestinal bleeding (GIB) is a leading cause of morbidity during continuous-flow left ventricular assist device (CF-LVAD) support. GIB risk assessment could have important implications for candidate selection, informed consent, and postimplant therapeutic strategies. The aim of the study is to derive and validate a predictive model of GIB in CF-LVAD patients. METHODS AND RESULTS CF-LVAD recipients at the Utah Transplantation Affiliated Hospitals program between 2004 and 2017 were included. GIB associated with a decrease in hemoglobin ≥2 g/dL was the primary end point. A weighted score comprising preimplant variables independently associated with GIB was derived and internally validated. A total of 351 patients (median age, 59 years; 82% male) were included. After a median of 196 days, GIB occurred in 120 (34%) patients. Independent predictors of GIB included age >54 years, history of previous bleeding, coronary artery disease, chronic kidney disease, severe right ventricular dysfunction, mean pulmonary artery pressure <18 mm Hg, and fasting glucose >107 mg/dL. A weighted score termed Utah bleeding risk score, effectively stratified patients based on their probability of GIB: low (0-1 points) 4.8%, intermediate (2-4) 39.8%, and high risk (5-9) 83.8%. Discrimination was good in the development sample (c-index: 0.83) and after internal bootstrap validation (c-index: 0.74). CONCLUSIONS The novel Utah bleeding risk score is a simple tool that can provide personalized GIB risk estimates in CF-LVAD patients. This scoring system may assist clinicians and investigators in designing tailored risk-based strategies aimed at reducing the burden posed by GIB in the individual CF-LVAD patient and healthcare systems.

Abstract
Objective: To observe the effectiveness and safety of topical 0.1% tacrolimus(FK506) as immunosuppressant in high-risk penetrating corneal transplantation to prevent the immune rejection and to compare the outcomes with topical 1% Cyclosporin A (CsA). Methods: The study consists of 49 patients (50 eyes), who were fitted with the high-risk corneal transplantation standard and undergone the penetrating keratoplasty(PKP) or combined operation in Beijing Tongren hospital between March 2015 to September. With the time sequence, the patients were divided into observation group (FK506 group) and the control group (CsA group). The observation group included 9 females and 16 males with an average age of 57.8±14.8. Twenty-four patients were in the control group (25 eyes), including 10 females and 14 males, with an average age of (45.1±16.2). Observation group was treated with topical 0.1% tacrolimus, and the control group treated with topical 1%CsA. Both groups' treatment combined glucocorticoid as well. Two groups had 1 year follow-up observation. The incidence of rejection was compared by statistical methods of Cox regression. The adverse reactions were graded and compared using Mann-Whitney U test. Results: After one year, 22 cases of the observation group and 23 cases of the control group were accomplished all observations. The rejection rate was 4.54% in observation group and 27.23% in control group. The difference between the groups was statistically significant (χ(2)=4.291, P=0.038). Control group had high rejection rate. Besides, there was no severe side effects happened in both groups. After 1 month after surgery, 36.4% of the observation group showed mild corneal edema. The ratio of mild to moderate corneal edema in the control group was 26.1% and 8.7%. Three months after surgery, 4.5% of the observation group showed mild corneal edema, while 13.0% and 13.0% of the control group was found mild to moderate corneal edema. Six months after surgery, 4.5% of the observation group showed moderate corneal edema. The ratio of mild, moderate to severe corneal edema in the control group was 17.4%, 17.4% and 8.7%. The degree of corneal edema in the control group was more serious in three monthes(Z=-2.770, -2.018, -2.941, P<0.05). The differences in both monthes were statistically significant. Mild neovascularization occurred in the 13.6% of observation group. Mild to severe neovascularization occurred in the 13.0%, 4.3%, and 4.3% control groups. The degree of neovascularization in the control group was higher than that in the observation group(Z=-3.221, P=0.001). The differences in both months were statistically significant. Mild to moderate neovascularization occurred in the 18.2% and 9.1% of observation group. Mild to extremely severe neovascularization occurred in the 17.4%, 26.1%, 4.3% and 4.3% control groups. The degree of neovascularization in the control group was higher than that in the observation group(Z=-1.988, P=0.047).The differences in both monthes were statistically significant. Conclusions: Both 0.1% tacrolimus and 1% cyclosporine A are safe and effective in reducing the rejection after high-risk corneal transplantation. (Chin J Ophthalmol, 2019, 55: 419-427).

Abstract
With the continuous development of endovascular surgery, thoracic endovascular aortic repair (TEVAR) has gradually replaced traditional open surgery and has become the preferred treatment strategy for Stanford type B aortic dissection. However, the disadvantage of the short proximal landing zone greatly limited the indication of TEVAR surgery and affected the prognosis. In recent years, many strategies such as hybrid surgery, in vitro fenestrated and branched aortic endo-graft, chimney technique, in-situ fenestration technique, etc., have been developed, which greatly broadens the TEVAR indication and improved the prognosis.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disease with major clinical hallmarks of memory loss, dementia, and cognitive impairment. Neuroinflammation is involved in the onset of several neurodegenerative disorders. Astrocyte is the most abundant type of glial cells in the central nervous system (CNS) and appears to be involved in the induction of neuroinflammation. Under stress and injury, astrocytes become astrogliotic leading to an upregulation of the expression of proinflammatory cytokines and chemokines, which are associated with the pathogenesis of AD. Cytokines and related molecules play roles in both neuroprotection and neurodegeneration in the CNS. During early AD pathogenesis, amyloid beta (Aβ), S100B and IL-1β could bring about a vicious cycle of Aβ generation between astrocytes and neurons leading to chronic, sustained and progressive neuroinflammation. In advanced stages of AD, TRAIL secreted from astrocytes have been shown to bind to death receptor 5 (DR5) on neurons to trigger apoptosis in a caspase-8-dependent manner. Furthermore, astrocytes could be reactivated by TGFβ1 to generate more Aβ and to undergo the aggravating astrogliosis. TGFβ2 was also observed to cooperate with Aβ to cause neuronal demise by destroying the stability of lysosomes in neurons. Inflammatory molecules can be either potential biomarkers for diagnosis or target molecules for therapeutic intervention. Understanding their roles and their relationship with activated astrocytes is particularly important for attenuating neuroinflammation in the early stage of AD. The main purpose of this review is to provide a comprehensive insight into the role of astrocytes in the neuroinflammatory pathogenesis of AD.

Abstract
In vitro studies of the effects of recombinant granulocyte macrophage-colony stimulating factor (rGM-CSF) on freshly obtained human leukemia cells were conducted to determine if there is a relationship between the effects of this growth factor on the proliferative characteristics of leukemia cells and on their incorporation of cytosine arabinoside (araC) into DNA. While rGM-CSF was found to be able to stimulate both leukemia cell proliferation and araC incorporation, for individual leukemia specimens there was no consistent relationship among these effects. In some specimens proliferation was stimulated without an increase in araC incorporation. The reverse was also observed. These studies demonstrate the difficulty in identifying assays capable of predicting the clinical effects of growth factors on leukemia cells in patients since the effect in vitro vary with the assay.

Abstract
Studies were conducted to determine the relationship between the pretherapy characteristics of leukemia cells and their behaviour during culture in vitro. Leukemia cells which proliferated well in vitro also proliferated well in vivo. Cells which manifested myeloid or monocytic differentiation in vivo tended to manifest differentiation along these lines in vitro. Cells which manifested high levels of expression of c-fms, c-fes, or triose phosphate isomerase prior to culture were likely to differentiate in vitro, with high levels of c-fes expression being related to myeloid maturation. These observations suggest that differentiation at the molecular level prior to culture is a requisite for leukemia cell differentiation in vitro. The same may be true for differentiation in vivo under the influence of exogenously administered agents such as cytotoxic chemotherapy or recombinant growth factors.

Abstract
Despite the profound differences between the chronic and blastic phases of chronic myelogenous leukaemia, no differences between chronic and blastic phase cells have been described at the molecular level. Differences have been found in the levels of expression of c-myc, c-myb and p53, which fell when chronic phase cells were cultured, while the levels of expression of the genes were stable when blastic crisis cells were cultured. In contrast c-fms expression increased and MRS expression decreased after culture of chronic or blastic phase cells. The data suggest that the regulation of expression of some genes in blastic crisis cells is unaltered while that of others is disrupted. It is not known whether the failure of c-myc, c-myb and p53 expression to fall during the culture of blastic phase cells is the cause of or a reflection of the failure of these cells to differentiate.

Abstract
An in vitro pilot study was conducted of the possible utility of combining low doses of cytosine arabinoside (araC) and GM-CSF to stimulate leukemic cell differentiation. Cytosine arabinoside induced macrophage differentiation in some cultures but only when the drug produced substantial cytostatic effects. GM-CSF, when present alone, failed to induce leukemic cell differentiation. When GM-CSF and araC were simultaneously present the level of both araC associated cytotoxicity and araC associated differentiation were reduced in 3 studies. In only a single study was there evidence suggesting that GM-CSF increased araC-associated differentiation.
