REVIEW
Hongluan Wang, Lixia Xiong, Weiping Tang, Ying Zhou, Fei Li
As an infrequent but potentially life-threatening hyperinflammatory syndrome, hemophagocytic lymphohistiocytosis (HLH) is clinically characterized with prolonged fever, hepatosplenomegaly, cytopenia, hypertriglyceridemia, hyperferritinemia and hemophagocytosis in bone marrow, liver, spleen or lymph nodes. Malignancy-associated HLH (M-HLH), one type of acquired HLH, usually presents variable overlaps of symptoms with other types of HLH, thus resulting in higher incidence of misdiagnosis and mortality. In recent years, with the increasing awareness to this disease, the diagnosis and management of HLH have gained more and more attention, and improvements have been made accordingly...

Elizabeth Woodward, Ann Hackmann, Jennifer Wild, Nick Grey, David M Clark, Anke Ehlers
The effectiveness and mechanisms of psychotherapies for posttraumatic stress disorder (PTSD) in treating sleep problems is of interest. This study compared the effects of a trauma-focused and a non-trauma-focused psychotherapy on sleep, to investigate whether 1) sleep improves with psychotherapy for PTSD; 2) the degree of sleep improvement depends on whether the intervention is trauma or nontrauma-focused; 3) the memory-updating procedure in cognitive therapy for PTSD (CT-PTSD) is associated with sleep improvements; 4) initial sleep duration affects PTSD treatment outcome; and 5) which symptom changes are associated with sleep duration improvements...

Yunduan Cui, Takamitsu Matsubara, Kenji Sugimoto
We propose a new value function approach for model-free reinforcement learning in Markov decision processes involving high dimensional states that addresses the issues of brittleness and intractable computational complexity, therefore rendering the value function approach based reinforcement learning algorithms applicable to high dimensional systems. Our new algorithm, Kernel Dynamic Policy Programming (KDPP) smoothly updates the value function in accordance to the Kullback-Leibler divergence between current and updated policies...

Levan Tsereteli, Andrea Grafmüller
Computational models can provide detailed information about molecular conformations and interactions in solution, which is currently inaccessible by other means in many cases. Here we describe an efficient and precise coarse-grained model for long polysaccharides in aqueous solution at different physico-chemical conditions such as pH and ionic strength. The Model is carefully constructed based on all-atom simulations of small saccharides and metadynamics sampling of the dihedral angles in the glycosidic links, which represent the most flexible degrees of freedom of the polysaccharides...

Pancreatitis is an inflammation of the pancreas that can progress from an acute presentation to an acute recurring presentation and eventually to chronic pancreatitis, which is characterized by irreversible morphological changes and scarring of the pancreas. The entity known as hereditary pancreatitis has been recognized in the literature for years and certainly the discovery of the PRSS1 gene in 1996 marked the beginning of a new era of genetic discoveries associated with the disease. Since then, multiple genes have been described as the causing agents of pancreatitis or disease modifiers, some of the most important ones being the PRSS1, SPINK1, CFTR, CASR, CTRC, CLDN2, and CPA1...

Chronic pancreatitis is a progressive fibro-inflammatory disease of the pancreas characterized by irreversible fibrosis of the gland with eventual failure of exocrine and endocrine functions and hallmark features of abdominal pain, malabsorption, malnutrition, diabetes mellitus and pancreatic calcifications. In many patients this disease results from a complex mix of environmental (eg, alcohol, cigarettes, and occupational chemicals), genetic factors and a few patients with hereditary or autoimmune disease...

BACKGROUND: The prognostic Kidney Donor Risk Index (KDRI)-developed and internally validated in the US-is a widely-used tool to predict transplant outcome of a deceased donor kidney. The KDRI is currently used for longevity matching between donors and recipients in the US. METHODS: We aimed to externally validate the KDRI as proposed by Rao et al, (2009) containing 10 donor factors (KDRIdonor-only) and 1 with 4 additional transplant factors (KDRIfull), with stratification on recipient age and diabetes...

PURPOSE OF REVIEW: The present study discusses the utilization of neuraxial drug delivery (NDD) for the management of cancer pain, based on recent trials, reviews, and guidelines with a focus on cost analysis. RECENT FINDINGS: Almost all recent publications suggest that more stringent research is needed to improve evidence on NDD, particularly as conflicting reports exist regarding cost effectiveness of drug delivery systems. The combination of local anesthetics and opioids, with or without clonidine, continues to be reported as beneficial with the utilization of patient controlled systems providing an advantage over continuous ones...

PURPOSE OF REVIEW: The main objective of this article is to present the updated data regarding the perioperative management of patients undergoing major spine surgery in an era where the surgical techniques are changing and there is a high demand for these surgeries in older and high-risk patients. RECENT FINDINGS: Preoperative assessment and stabilization is now more structured protocol and it is based on a multidisciplinary approach to the patient. The Enhanced Recovery After Surgery (ERAS) programs and the Perioperative Surgical Home on major spine surgery are not yet fully evidence based but it seems that the use of a perioperative optimization of patients and use of a drugs' bundle is more effective than using single drugs or interventions on the postoperative pain reduction and faster recovery from surgery...

REVIEW
Patricio Kenny
Cry-fuss problems are among the most common clinical presentations in the first few months of life. Cry-fuss behaviour emerges out of a complex interplay of cultural, psychosocial, environmental and biologic factors, with organic disturbance implicated in only 5% of cases. A holistic biopsychosocial approach can be most effective. This article reviews recent evidence to update clinical management, and will attempt to reconceptualize infant colic definition.

Achieving adequate lighting in neonatal intensive care units is a major challenge: in addition to the usual considerations of visual performance, cost, energy and aesthetics, there appear different biological needs of patients, health care providers and family members. Communicational aspects of light, its role as a facilitator of the visual function of doctors and nurses, and its effects on the newborn infant physiology and development were addressed in order to review the effects of light (natural and artificial) within neonatal care with a focus on development...

BACKGROUND: Registry data shows that the incidence of acute rejection has been steadily falling. Approximately 10% to 35% of kidney recipients will undergo treatment for at least one episode of acute rejection within the first post-transplant year. Treatment options include pulsed steroid therapy, the use of an antibody preparation, the alteration of background immunosuppression, or combinations of these options. Over recent years, new treatment strategies have evolved, and in many parts of the world there has been an increase in use of tacrolimus and mycophenolate and a reduction in the use of cyclosporin and azathioprine use as baseline immunosuppression to prevent acute rejection...

Phlebotomine (Diptera, Psychodidae, Phlebotominae) taxonomy has been studied extensively, primarily due to the role of these flies as vectors of various parasites, including species of Leishmania, Bartonella and arboviruses that cause diseases in humans and other vertebrates. We present some topics discussed at a round-table on phlebotomine taxonomy held at the Ninth International Symposium on Phlebotomine Sandflies (ISOPS IX) in Reims, France, in June 2016. To date, approximately one thousand phlebotomine species have been described worldwide, although in varying languages and mostly without standardization of characters and terminology...
