Hemophagocytosis by Leukemic Blasts in T Cell Acute Lymphoblastic Leukemia: An Unusual Finding

Hemophagocytosis shows engulfment of hematopoietic cells by histiocytes and is a property generally associated with cells of the histiocytic lineage. It can be familial or is seen in a wide spectrum of acquired disorders. Hemophagocytosis by leukemic blasts is an uncommon phenomenon and has been reported mainly in acute myeloid leukemia. Its association with acute lymphoblastic leukemia is rare. We present a case of hemophagocytosis by blasts in the bone marrow in a 11 year old boy with T cell-acute lymphoblastic leukemia.     

Nutritional Strategies in the Management of Adult Patients with Inflammatory Bowel Disease: Dietary Considerations from Active Disease to Disease Remission

Inflammatory bowel disease (IBD) is a group of chronic, lifelong, and relapsing illnesses, such as ulcerative colitis and Crohn’s disease, which involve the gastrointestinal tract. There is no cure for these diseases, but combined pharmacological and nutritional therapy can induce remission and maintain clinical remission. Malnutrition and nutritional deficiencies among IBD patients result in poor clinical outcomes such as growth failure, reduced response to pharmacotherapy, increased risk for sepsis, and mortality. The aim of this review is to highlight the consequences of malnutrition in the management of IBD and describe nutritional interventions to facilitate induction of remission as well as maintenance; we will also discuss alternative delivery methods to improve nutritional status preoperatively.     

The development of sweet taste: From biology to hedonics

From the age of 2 years, an American child is more likely to consume a sugar-sweetened product than a fruit or vegetable on any given day—a troubling statistic, given that food preferences are established early in childhood, as well as the strong association between this dietary pattern and increased risk of developing a number of chronic diseases. Here, we review the ontogeny and biopsychology of sweet taste, highlighting how a biological drive to prefer sweetness at high concentrations during childhood, which would have conferred an advantage in environments of scarcity, now predisposes children to overconsume all that is sweet in a modern food system replete with added sugars. We review the power of sweet taste to blunt expressions of pain and mask bad tastes in foods as well as factors that predispose some to consume high-sugar diets, including experiential learning and taste preferences driven in part by genetics. Understanding children’s unique vulnerability to our current food environment, rich in both nutritive and nonnutritive sweeteners, is highlighted as a priority for future research to develop evidence-based strategies to help establish healthy dietary behaviors early in life.     

Complex Fistula Disease in the Pelvic Malignancy Cancer Survivor Who Has Been Treated with Radiation

Fistulation is a relatively uncommon complication resulting from the treatment of pelvic malignancy but one which is associated with significant patient morbidity. Fistulae complicating treatment with radiation, when compared to those arising from surgical management alone, are usually more difficult to treat by virtue of tissue ischaemia and fibrosis. They are also commonly associated with other complications resulting from the effect of radiation on adjacent organs such as the bladder, lower intestinal tract and pelvic bones as well as the frequent occurrence of intervening cavitation and chronic pelvic sepsis, all of which render these fistulae complex. Complex radiotherapy fistulae necessitate a change in the standard approach to fistula management. In a non-tertiary setting, they are often treated by urinary or bowel diversion (or both). Surgical correction of complex fistulae following radiotherapy is nonetheless possible in experienced hands but commonly requires extensive reconstructive procedures via an abdominoperineal approach with a protracted recovery and reduced potential for return to complete functional normality.     

Is Transforming Stem Cells to Pancreatic Beta Cells Still the Holy Grail for Type 2 Diabetes?

Diabetes is a progressive disease affecting millions of people worldwide. There are several medications and treatment options to improve the life quality of people with diabetes. One of the strategies for the treatment of diabetes could be the use of human pluripotent stem cells or induced pluripotent stem cells. The recent advances in differentiation of stem cells into insulin-secreting beta-like cells in vitro make the transplantation of the stem cell-derived beta-like cells an attractive approach for treatment of type 1 and type 2 diabetes. While stem cell-derived beta-like cells provide an unlimited cell source for beta cell replacement therapies, these cells can also be used as a platform for drug screening or modeling diseases.     

Future Therapy for Hepatitis B Virus and Hepatitis D Virus

Chronic delta hepatitis (CDH) represents the least encountered but the most severe form of chronic viral hepatitis. Whereas in other forms of chronic viral hepatitis breakthrough advances has occurred in the last two decades, this did not happen in CDH. The only effective treatment in CDH consists of the use of pegylated interferons. Interferon therapy has to be given at high doses, and the optimal duration is unknown although there is data to suggest that treatment has to be individualized and prolonged treatment duration beyond 1 year is necessary. Effective treatment of chronic hepatitis B (CHB) could be of value in CDH as long as it significantly decreases hepatitis B surface antigen (HBsAg) levels. However, nucleos(t)ide analogs currently in use for the treatment of CHB do not affect HBsAg levels and are not beneficial in CDH. New treatment approaches for CHB aiming for functional or complete cure in CHB are attractive but most are in the preclinical stage of drug development and are not expected to be in use in the very near future. Hence, treatment development targeting different steps of the hepatitis delta virus is rationale. These include hepatocyte entry inhibitors, nucleic acid polymers, and prenylation inhibitors. The former two approaches may also be considered for CHB mono-infection. Studies on these three approaches have reached phase 2 studies in humans. The use of the hepatocyte entry inhibitor myrcludex B, several nucleic acid polymers, and the prenylation inhibitor lonafarnib in clinical trials have displayed some promising results and further data need to be generated but there is now, after decades of silence in terms of translational activity, for the first time a hope for effective new treatments in CDH.     

Soziale Netzwerkanalyse und das soziale Atom

This article in the Zeitschrift für Psychodrama und Soziometrie shows how modern Network Analysis, partly rooting in Moreno’s work may become more effective in transforming social contexts by recalling some aspects of Moreno’s pioneering work. Over the last few decades modern network analysis has developed into a powerful and differentiated instrument for relationship analytics, while increasingly lacking the ability to put results into context, so analyses often remain mere data.It seems inevitable to go back to the basics of Moreno’s pioneering work: only this enables to put things into a meaningful context, that insights become operative and to recognize networks as spaces for encounters again and thus as spaces for creativity and therapy. Both in Moreno’s time and nowadays there is much at stake: then and now we run the risk to lose these spaces of creativity, these spaces of healing.     

The Protective Role of Self-Compassion on Risk Factors for Non-suicidal Self-Injury in Adolescence

Non-suicidal self-injury (NSSI) in adolescence is a serious public health problem. Although self-compassion is a protective factor of mental health difficulties in adult populations, its potential impact on adolescence remains scarcely explored. Therefore, we aimed to test whether self-compassion can mitigate the impact of daily peer hassles and depressive symptoms on NSSI. The participants were 643 adolescents (51.6 % female) with ages between 12 and 18 years, from middle and secondary schools. Self-report questionnaires were used to measure daily peer hassles, depressive symptoms, self-compassion and NSSI. Daily peer hassles were positively correlated with depressive symptoms and NSSI. Self-compassion was inversely associated with daily peer hassles and depressive symptoms and NSSI. Path analysis showed that self-compassion had a moderator effect on the association between depressive symptoms and NSSI. Results suggest that self-compassion can be a protective process, as it may buffer against the impact of depressive symptoms on NSSI. This study presents preventive and clinical implications for educators and therapists working with adolescents.
