LncRNA LINC00899 mediates cell proliferation and apoptosis of acute myeloid leukaemia cells. Knockdown of LINC00899 inhibited the growth of xenograft glioma tumour in vivo. LINC00899 acts as a molecular sponge of miR-744-3p. YY1 is the downstream target of LINC00899/miR-744-3p signalling. © 2020 John Wiley & Sons Ltd.The “glycolytic switch” also known as the “Warburg effect” is a key feature of tumor cells and leads to the accumulation of lactate and protons in the tumor environment. Intriguingly, non-malignant lymphocytes or stromal cells such as tumor-associated macrophages and cancer-associated fibroblasts contribute to the lactate accumulation in the tumor environment, a phenomenon described as the “Reverse Warburg effect.” Localized lactic acidosis has a strong immunosuppressive effect and mediates an immune escape of tumors. However, some tumors do not display the Warburg phenotype and either rely on respiration or appear as a mosaic of cells with different metabolic properties. Based on these findings and on the knowledge that T cell infiltration is predictive for patient outcome, we suggest a metabolic-tumor-stroma score to determine the likelihood of a successful anti-tumor immune response (a) a respiring tumor with high T cell infiltration (“hot”); (b) a reverse Warburg type with respiring tumor cells but glycolytic stromal cells; (c) a mixed type with glycolytic and respiring compartments; and (d) a glycolytic (Warburg) tumor with low T cell infiltration (“cold”). Here, we provide evidence that these types can be independent of the organ of origin, prognostically relevant and might help select the appropriate immunotherapy approach. © 2020 The Authors. Immunological Reviews published by John Wiley & Sons Ltd.We report the case of a child who presented with a giant melanocytic nevus with numerous satellite nevi at birth and developed hypophosphatemic rickets due to excessive secretion of the FGF23 hormone. A NRAS c.182A>G (Q61R) mutation was identified in the lesional skin. The functional outcome was favorable with medical treatment. © 2020 Wiley Periodicals, Inc.Bariatric (weight loss) surgery modifies the digestive system, which produces impairments and symptoms which might be considered illness or disability. Bariatric patients, however, do not view themselves as ill or disabled, but healthier than before surgery. For this study, 35 bariatric patients – from a clinic located in the Midwestern United States – were interviewed to investigate how moral and medical discourses surrounding obesity impact how patients experience their bodies after bariatric surgery. While previous literature on bariatric patients has explored discourses of medicine, stigma and discipline, fewer have analysed how patients interpret physiological symptoms. Patients often reduce or discontinue medications for chronic illness after bariatric surgery, then replace them with a strict regimen of dietary supplements. Even though these supplements are taken to manage an impaired digestive system, they do not carry the same moral weight as medications for chronic illness. Patients also experience painful and humiliating symptoms after bariatric surgery. Bariatric patients interpret symptoms not as illness, but as important disciplinary tools to lose weight. These findings have implications for the social construction and experience of illness and disability in the context of fat stigma, health morality and biomedicalisation. © 2020 Foundation for the Sociology of Health & Illness.BACKGROUND This study evaluated and compared cardiorespiratory and blood gas parameters, as well as sedation, analgesia and recovery of two protocols ketamine (10 mg/kg) or dexmedetomidine (10 μg/kg), with midazolam (0.5 mg/kg) and butorphanol (0.3 mg/kg), IM (KBM and DBM, respectively) in brown howler monkeys (Alouatta guariba clamitans). MATERIAL AND METHODS Twelve brown howler monkeys were selected in two groups and evaluated for cardiorespiratory parameters and sedation, from 5-30 minutes after latency. Blood gas and arterial lactate were taken at 5 and 30 minutes. In the end, time and quality of recovery were evaluated. RESULTS The HR in DBM group was significantly lower at all times. The sedation score was higher in DBM. Recovery in DBM was faster. All animals had moderate hypoxaemia. CONCLUSION Both protocols produce satisfactory anaesthesia and analgesia, but DBM provides deeper sedation with faster recovery. Oxygen supplementation is recommended in both due to hypoxaemia. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.Nurses play an important role in supporting patients in self-managing their chronic conditions. However, it is uncertain how nurses define their success and what might create feelings of disillusionment. This exploratory qualitative study sought to understand the origin, meanings, and processes underlying nurses’ feelings of success in supporting patients to self-manage their life with a chronic illness. Semi-structured interviews were held with 16 nurses who were purposively sampled. Data were iteratively collected and analyzed (November 2017-September 2018). Ferrostatin-1 The origin and meaning of nurses’ feelings of success in supporting patients in self-management converged around the intertwining of “maintaining and promoting health” as a primary goal in chronic care, while an “intrapersonal conflict” arises. Patients maintaining physical health by optimal medical management boost nurses’ feelings of success, whereas patients dealing with sub-optimally provoke “an intrapersonal conflict”. When nurses observe unhealthy patient behavior, this is difficult to accept as it conflicts with their normative ideas of good care and health. Nurses’ perception of success is refined by three interconnected processes, namely “keeping on track”, “considering own role,” and “protecting self”. Nurses experienced and processed success differently depending on whether they interacted with patients from a more directive approach or an attuning approach. This study highlighted the fact that nurses expect compliance from patients, and thereby often feel empty-handed. By adopting a broader perspective of what successful patient behavior is, nurses might be able to provide a more comprehensive meaning to their own success regarding the care of patients living with a chronic illness. © 2020 Wiley Periodicals, Inc.
