Rock music and hearing loss - to quote Who singer Roger Daltrey: "We’re all going deaf. We’re all wearing hearing aids"
How’s your hearing?
My hearing’s dreadful. We’re all going deaf. We’re all wearing hearing aids. No it’s true. I suggest to everybody over the age of 50 that have been going to loud concerts for years and years and years, go and have your hearing tested. You’d be surprised what you’re missing. It’s unbelievable. Most people over the age of 60 are lip-reading. (Jokes) And it’s all our fault!
How do you keep your voice in shape?
If you don’t use it, you lose it, simple as that. And too many of our generation they think they’ve made it and they come off the road for four or five years and don’t sing and before they know it the muscles that you need to be there for you, to hit the notes, have disappeared. And you can get them back. But sometimes you leave it too long and it’s gone forever.
How do you keep your famous body in shape?
I do about 20 minutes in the gym these days. Hardly anything. I’m getting lazier and lazier. I do a lot of walking. I love to walk. Five miles a day I average.

Cuticle and subsurface ornamentation of intact plant leaf epidermis under confocal and superresolution microscopy
ABSTRACT
Plant cuticle micromorphology is an invaluable tool in modern ecology and paleoecology. It has expanded our knowledge of systematic relationships among diverse plant groups and can be used to identify fossil plants. Furthermore, fossil plant leaf micromorphology is used for reconstructing past environments, most notably for estimating atmospheric CO2 concentration. Here we outline a new protocol for imaging plant cuticle for archival and paleoecological applications. Traditionally, both modern reference and fossil samples undergo maceration with subsequent imaging via environmental SEM, widefield fluorescence, or light microscopy. In this paper, we demonstrate the capabilities of alternative preparation and imaging methods using confocal and superresolution microscopy with intact leaf samples. This method produces detailed three-dimensional images of surficial and subsurface structures of the intact leaf. Multiple layers are captured simultaneously, which previously required independent maceration and microtome steps. We compared clearing agents (chloral hydrate, KOH, and Visikol); mounting media (Eukitt and Hoyer's); fluorescent stains (periodic acid Schiff, propidium iodide); and confocal vs. superresolution microscopes. We conclude that Eukitt is the best medium for long-term preservation and imaging. Because of nontoxicity and ease of procurement, Visikol made for the best clearing agent. Staining improves contrast and under most circumstances PAS provided the clearest images. Supperresolution produced higher clarity images than traditional confocal, but the information gained was minimal. This new protocol provides the botanical and paleobotanical community an alternative to traditional techniques. Our proposed workflow has the net benefit of being more efficient than traditional methods, which only capture the surface of the plant epidermis. Microsc. Res.

Direct perturbation of neural integrator by bilateral galvanic vestibular stimulation.
Direct perturbation of neural integrator by bilateral galvanic vestibular stimulation.
Med Biol Eng Comput. 2016 Apr 23;
Authors: Hong K, Shim HM, Goh M, Jang SY, Lee S, Kim KS
Abstract
Caloric vestibular stimulation (CVS) and galvanic vestibular stimulation (GVS) act primarily on the peripheral vestibular system. Although the electrical current applied during GVS is thought to flow through peripheral vestibular organs, some current may spread into areas within the central nervous system, particularly when the bilateral galvanic vestibular stimulation (bGVS) method is used. According to Alexander's law, the magnitude of nystagmus increases with eccentric gaze movement, due to the function of the neural integrator (NI); thus, if the information for vestibular stimulation corresponds to Alexander's law, the peripheral vestibular organ is stimulated. Therefore, it would appear that if CVS results comply with Alexander's law, and bGVS results do not, the sites stimulated by bGVS are not perfectly located in the peripheral vestibular area. In our experiments on normal human subjects, the magnitude of nystagmus under CVS increased with rising gaze eccentricity in the direction that the magnitude of the nystagmus increases, and this change was found to follow Alexander's law. However, in the case of nystagmus under bGVS, results did not follow Alexander's law. In addition, study of the influences of bGVS at different current intensities on nystagmus magnitude showed that bGVS at 5 mA distorted nystagmus magnitude more than at 3 mA, which suggests bGVS acts not only on the peripheral vestibular nerves, but also on some areas of the central nervous system, particularly the NI. According to our experiments, bGVS directly affects neural integrator function.

Abstract
Integrins play key roles in the regulation of tumor cell adhesion, migration, invasion and sensitivity to anticancer drugs. In the present study we investigate the mechanism of resistance of tongue squamous carcinoma cells Cal27 with de novo integrin αvβ3 expression to anticancer drugs. Cal27-derived cell clones, obtained by transfection of plasmid containing integrin subunit β3 cDNA, as compared to control cells demonstrate: expression of integrin αvβ3; increased expression of integrin αvβ5; increased adhesion to fibronectin and vitronectin; resistance to cisplatin, mitomycin C, doxorubicin and 5-fluorouracil; increased migration and invasion, increased amount of integrin-linked kinase (ILK) and decreased amounts of non-receptor tyrosine kinase (Src) and pSrc(Y418). Knockdown of ILK and integrin β5 in cells expressing integrin αvβ3 ruled out their involvement in drug resistance. Opposite, Src knockdown in Cal27 cells which led to a reduction in pSrc(Y418), as well as treatment with the pSrc(Y418) inhibitors dasatinib and PP2, conferred resistance to all four anticancer drugs, indicating that the loss of pSrc(Y418) is responsible for the observed effect. We identified differential integrin signaling between Cal27 and integrin αvβ3-expressing cells. In Cal27 cells integrin αv heterodimers signal through pSrc(Y418) while this is not the case in integrin αvβ3-expressing cells. Finally, we show that dasatinib counteracts the effect of cisplatin in two additional head and neck squamous cell carcinoma (HNSCC) cell lines Cal33 and Detroit562. Our results suggest that pSrc(Y418) inhibitors, potential drugs for cancer therapy, may reduce therapeutic efficacy if combined with chemotherapeutics, and might not be recommended for HNSCC treatment.

Abstract
Acantholytic squamous cell carcinoma is an uncommon variant of squamous cell carcinoma. Acantholytic squamous cell carcinoma occurs in the sun-exposed areas of the skin and lip. It is rarely observed in the respiratory and digestive tract and may present more aggressively. The incidence of distant metastases of squamous cell head and neck cancers is low and the lungs are the most common metastatic sites. Metastasis to the soft tissue, skin, and adrenal glands from the laryngeal region is very uncommon. In this article, we report a 58-year-old female case who underwent postoperative radiation therapy with the diagnosis of acantholytic squamous cell carcinoma of the larynx and developed metastasis to the soft tissue and adrenal gland at the early period.

Pectoralis major myofascial interposition flap prevents postoperative pharyngocutaneous fistula in salvage total laryngectomy.
Pectoralis major myofascial interposition flap prevents postoperative pharyngocutaneous fistula in salvage total laryngectomy.

Authors: Anschütz L, Nisa L, Elicin O, Bojaxhiu B, Caversaccio M, Giger R
Abstract
Pharyngocutaneous fistula (PCF) is the most cumbersome complication after salvage total laryngectomy (STL) in patients who have been previously irradiated for laryngeal or hypopharyngeal cancer. To assess the fistula rate, risk factors and effects of primary closure with and without pectoralis major myofascial interposition flap (PMMIF) on fistula formation, we conducted a retrospective review. We identified 48 patients from 2004 to 2013 who underwent STL after failure of primary curative (chemo)radiotherapy in laryngeal or hypopharyngeal cancer. Details of risk factors for PCF formation, other postoperative complications and general outcome data were analyzed. Ten (20.8 %) out of 48 patients underwent STL with PMMIF closure. Patient and tumor features were not different between the groups with or without PMMIF closure. PCF rates were 0 and 42.1 % in patients with and without PMMIF, respectively (p = 0.002). Other operative complications were similar. We identified prior neck irradiation to be a risk factor for fistula formation (p = 0.04). Patients without PCF had a statistically significant reduction of average hospital stay (20 vs. 56 days; p = 0.001). Analysis of fistula management revealed 50 % of PCF to be closed secondarily by a pectoralis major myocutaneous flap. Over one-third of fistulae persisted despite attempted surgical closure in some cases. PMMIF is useful to prevent PCF in STL following (chemo)radiotherapy. Neck irradiation during primary treatment is a risk factor for PCF formation.

Mandibular melanotic neuroectodermal tumor of infancy: a role for neoadjuvant chemotherapy.
Mandibular melanotic neuroectodermal tumor of infancy: a role for neoadjuvant chemotherapy.
Eur Arch Otorhinolaryngol. 2016 Apr 23;
Authors: Maroun C, Khalifeh I, Alam E, Akl PA, Saab R, Moukarbel RV
Abstract
Melanotic Neuroectodermal Tumor of Infancy (MNTI) is a rare, locally aggressive neoplasm with a predilection for the head and neck area, most commonly occurring in the maxilla. The vast majority of treatment modalities for all cases of MNTI to date have involved surgical intervention only, with just 9.6 % involving some sort of chemotherapy, radiotherapy, or a combination of the prior mentioned modalities. There is very limited information available regarding the use of neoadjuvant chemotherapy, due to its rare nature. In this report, a 4 month old girl presented to our clinic with a chief complaint of a large oral mass of about 2.5 months in duration. Intraoral examination showed an oral mass arising from the lingual aspect of inferior alveolar ridge with extensive mandibular invasion. The patient received three cycles of vincristine, Adriamycin, and cyclophosphamide as neodajuvant therapy. Upon completion, the tumor had decreased significantly in size. The patient was then scheduled for surgery and underwent surgical resection of the tumor. We were able to obtain adequate shrinkage of the tumor to allow better resectability, easier surgical access and a more minimally invasive approach with no lip split and a smaller neck incision. In conclusion, we have reported an extremely rare case of MNTI of the mandible that was successfully treated with neoadjuvant chemotherapy and surgical resection. This approach was advantageous to minimize the chance of recurrence and improve resectability in particularly large tumors, while maximizing functional outcomes and minimizing deformity.

Post-transcriptional control of the mammalian circadian clock: implications for health and disease.
Post-transcriptional control of the mammalian circadian clock: implications for health and disease.
Pflugers Arch. 2016 Apr 23;
Authors: Preußner M, Heyd F
Abstract
Many aspects of human physiology and behavior display rhythmicity with a period of approximately 24 h. Rhythmic changes are controlled by an endogenous time keeper, the circadian clock, and include sleep-wake cycles, physical and mental performance capability, blood pressure, and body temperature. Consequently, many diseases, such as metabolic, sleep, autoimmune and mental disorders and cancer, are connected to the circadian rhythm. The development of therapies that take circadian biology into account is thus a promising strategy to improve treatments of diverse disorders, ranging from allergic syndromes to cancer. Circadian alteration of body functions and behavior are, at the molecular level, controlled and mediated by widespread changes in gene expression that happen in anticipation of predictably changing requirements during the day. At the core of the molecular clockwork is a well-studied transcription-translation negative feedback loop. However, evidence is emerging that additional post-transcriptional, RNA-based mechanisms are required to maintain proper clock function. Here, we will discuss recent work implicating regulated mRNA stability, translation and alternative splicing in the control of the mammalian circadian clock, and its role in health and disease.

Obstructive sleep apnea and Fuhrman grade in patients with clear cell renal cell carcinoma treated surgically.
Obstructive sleep apnea and Fuhrman grade in patients with clear cell renal cell carcinoma treated surgically.
World J Urol. 2016 Apr 23;
Authors: Vilaseca A, Nguyen DP, Vertosick EA, Corradi RB, Musquera M, Pérez M, Fossati N, Sjoberg DD, Farré R, Almendros I, Montserrat JM, Benfante NE, Hakimi AA, Skanderup AJ, Russo P, Alcaraz A, Touijer KA
Abstract
PURPOSE: To assess the association between obstructive sleep apnea (OSA) and Fuhrman grade in patients with clear cell renal cell carcinoma (ccRCC). As secondary endpoints, we studied its association with tumor size, metastasis-free survival (MFS) and cancer-specific survival (CSS).
METHODS: We reviewed the databases of two tertiary care centers, identifying 2579 patients who underwent partial or radical nephrectomy for ccRCC between 1991 and 2014. Descriptive statistics were used to compare pathologic variables between patients with and without OSA. Linear and logistic regression models were used to assess the association of OSA with Fuhrman grade and tumor size. A Cox proportional hazards model was used to determine OSA association with MFS and CSS. A pathway analysis was performed on a cohort with available gene expression data.
RESULTS: In total, 172 patients (7 %) had self-reported OSA at diagnosis. More patients with OSA had high Fuhrman grade compared to those without OSA [51 vs. 38 %; 13 % risk difference; 95 % confidence interval (CI), 5-20 %; p = 0.003]. On multivariable analysis, the association remained significant (OR 1.41; 95 % CI 1.00-1.99; p = 0.048). OSA was not associated with tumor size (p > 0.5), MFS (p = 0.5) or CSS (p = 0.4). A trend toward vascular endothelial growth factor pathway enrichment was seen in OSA patients (p = 0.08).
CONCLUSIONS: OSA is associated with high Fuhrman grade in patients undergoing surgery for ccRCC. Pending validation of this novel finding in further prospective studies, it could help shape future research to better understand etiological mechanisms associated.

The impact of dexamethasone and prednisone on sleep in children with acute lymphoblastic leukemia.
The impact of dexamethasone and prednisone on sleep in children with acute lymphoblastic leukemia.
Support Care Cancer. 2016 Apr 23;
Authors: Daniel LC, Li Y, Kloss JD, Reilly AF, Barakat LP
Abstract
PURPOSE: Corticosteroids can affect sleep patterns, mood, and behavior. Two of the most commonly prescribed corticosteroids in acute lymphoblastic leukemia (ALL), dexamethasone and prednisone, may impact sleep differently, but no research has compared these medications in children. The current study tested the hypothesis that dexamethasone and prednisone differentially affect sleep in children with ALL to understand how these medications contribute to health-related quality of life (HRQL).
METHODS: Parents of 81 children 3-12 years old in maintenance therapy for ALL completed a baseline measure of child sleep (dexamethasone n = 55, prednisone n = 26), and 61 parents returned 28 days of child sleep diaries starting the first day of a 5-day steroid course (dexamethasone n = 43, prednisone n = 18). Parents also completed measures of HRQL and fatigue on the last day of steroids and the last day of the month.
RESULTS: At baseline, parents reported more sleep disturbances in children taking dexamethasone than prednisone. Across the month, children taking dexamethasone experienced poorer sleep quality compared to children taking prednisone. During corticosteroid treatment, children taking dexamethasone also experienced more night awakenings than children taking prednisone. Sleep variables accounted for almost half of the variance in HRQL during time off steroids and also significantly contributed to fatigue during the corticosteroids course and time off corticosteroids.
CONCLUSIONS: Sleep is an essential component of HRQL in children taking corticosteroids, and the impact on sleep is more pronounced in children taking dexamethasone compared to prednisone. Screening for sleep disturbances and offering brief interventions to manage steroid-related sleep disruptions may improve HRQL.

Abstract
Growth factors involved in neurogenesis and neuroplasticity could play a role in biological processes that drive depression recovery. Combined total sleep deprivation and morning light therapy (TSD + LT) can acutely reverse depressive symptoms, thus allowing to investigate the neurobiological correlates of antidepressant response. We tested if changes on plasma levels of Brain Derived Neurotrophic Factor (BDNF), S100 calcium binding protein B (S100-B), Stem Cell Factor (SCF), Insulin-like Growth Factor-Binding Protein 2 (IGFBP-2), Epidermal Growth Factor (EGF), Platelet-Derived Growth Factor-BB (PDGF-BB), and Vascular Endothelial Growth Factor (VEGF) are associated with response to TSD + LT in 26 inpatients affected by a major depressive episode in the course of bipolar disorder. Regional grey matter (GM) volumes were assessed at baseline, and BOLD fMRI neural responses to a moral valence decision task were recorded before and after treatment. 61.5 % of patients responded to treatment. SCF plasma levels increased significantly more in responders, and correlated with GM volumes in frontal and parietal cortical areas. The pattern of change of SCF also associated with both GM volumes and changes of BOLD fMRI neural responses in the anterior cingulate and medial prefrontal cortex. SCF is both a hematopoietic growth factor and a neurotrophic factor, involved in neuron-neuron and neuron-(micro) glia interactions, fostering neuronal growth and an anti-inflammatory milieu. We correlated SCF levels with antidepressant response and with functional and structural MRI measures in cortical areas that are involved in the cognitive generation and control of affect. SCF may be a candidate growth factor that contributes to neurotrophic and immune effects that are involved in the process of remission/recovery from depression.

[Prevalence and initial management of overactive bladder in France: A cross-sectional study].
Prog Urol. 2016 Apr 20;
Authors: Cornu JN, Amarenco G, Bruyere F, Chartier-Kastler E, Fatton B, Grise P, Haab F, Bourouina R
Abstract
AIMS: To determine the prevalence of overactive bladder (OAB) syndrome in France and gather data about initial patient trajectories in the healthcare system.
METHODS: A dedicated questionnaire (41 questions) has been sent to a 12,000 sample of people representative of the global population. The following data were investigated: social and demographic features, medical history, Urinary Symptom Profile questionnaire, bother, history of symptoms, care seeking and treatments received. Patient were considered having OAB in case if presenting at least two episodes of urgency per week, or being under treatment of OAB. OAB prevalence was the main outcome, and associated factors were characterized by univariate and multivariate analysis.
RESULTS: Based on 8842 available questionnaires, the global prevalence of OAB was estimated to be 14.4%. Prevalence was significantly higher in women, older age groups, as well as obesity, irritable bowel syndrome, urinary tract infections, enuresia, constipation, anxiety/depression, neurological diseases, sleep apnea syndrome, asthma, chronic obstructive pulmonary disease, diabetes and hypertension. Only 34.6% of patients with OAB had visited a health practitioner for this problem. General practitioners were most frequently implicated in patient primary care and evaluation. Seventy-two percent of patients with OAB had had additional investigations (mostly a urine culture) and only 6% of patients had to complete a bladder diary. The most frequent treatment option was oral antimuscarinics. Physical therapy and rehabilitation have been prescribed in 26% of cases, as well as dietary advice.
CONCLUSIONS: OAB is a frequent syndrome. Its prevalence increases with age, and OAB frequently concern elderly frail people with many other associated diseases.

Postoperative Analgesia in a Prolonged Continuous Interscalene Block Versus Single-Shot Block in Outpatient Arthroscopic Rotator Cuff Repair: A Prospective Randomized Study.
Postoperative Analgesia in a Prolonged Continuous Interscalene Block Versus Single-Shot Block in Outpatient Arthroscopic Rotator Cuff Repair: A Prospective Randomized Study.
Arthroscopy. 2016 Apr 20;
Authors: Malik T, Mass D, Cohn S
Abstract
PURPOSE: To compare the analgesic efficacy of 3-day continuous interscalene brachial plexus block versus a single-shot block for arthroscopic rotator cuff repair.
METHODS: Eighty-five patients scheduled for arthroscopic rotator cuff repair were randomly assigned to either the single-shot group (SSG) or continuous interscalene brachial block group (CG). Patients in the SSG received 2.5 mg/kg of 0.5% bupivacaine up to 25 mL; the CG received the same dose as a loading dose via catheter followed by an infusion of 0.125% bupivacaine at 5 mL/h and a patient-controlled bolus of 5 mL hourly for 72 hours. Follow-up after discharge was with telephone calls over the next 3 days. Pain was measured on a visual analog scale. Also measured were sleep disturbance, number of opioid doses taken, adverse effects, and level of patient satisfaction.
RESULTS: The median rest pain scores on the 3 days of follow-up measured on a scale of 0 to 10 (with 10 equal to greatest pain) were 0, 0, and 3 in the CG compared with 4, 4, and 3 in the SSG (P < .001) for days 1, 2, and 3, respectively. The median maximum scores were 2, 2, and 4 in the CG compared with 8, 7, and 6 in the SSG (P < .001) for the same time period.
CONCLUSION: A 3-day continuous interscalene brachial plexus block provides better analgesia than a single-shot block. Sleep patterns were better, and less opioid was needed after arthroscopic rotator cuff repair in patients given a continuous plexus block.
LEVEL OF EVIDENCE: Level I, prospective randomized study.

Clinical relevance of molecular diagnosis in pet allergy
Abstract
We describe the pattern of sensitisation to pet IgE components and its association with clinical symptoms.
159 consecutive patients with rhinitis/asthma sensitised to dog, cat, and horse were recruited. Specific IgE to whole extracts and to pet recombinant allergens were performed. Only 5% of patients were monosensitised to animal allergens.
Specific IgE to Can f 1 was significantly associated with persistent rhinitis, Can f 2 with asthma diagnosis, Can f 3 with moderate/severe rhinitis (M/S-R) and asthma diagnosis (AD), and Can f 5 with persistent and M/S-R. Positive IgE to Fel d 2 was significantly associated with M/S-R and AD, Equ c 1 with M/S-R and Equ c 3 with persistent rhinitis, AD and severe asthma. Sensitisation to ≥2 molecules or to pet albumins was associated with more severe respiratory symptoms. Molecular diagnosis in patients with pet allergy may also help clinicians to predict clinical symptoms and their severity.

Acupuncture for Dyspnea in Lung Cancer: Results of a Feasibility Trial
Purpose. Dyspnea is a common and distressing symptom for patients with lung cancer (LC) because of disease burden, therapy toxicity, and comorbid illnesses. Acupuncture is a centuries-old therapy with biological plausibility for relief of dyspnea in this setting. This pilot study aimed to evaluate the feasibility and preliminary effectiveness of acupuncture for dyspnea among patients with LC. Methods. Eligible patients had a diagnosis of LC and clinically significant dyspnea without a clear organic cause. The treatment consisted of 10 weekly acupuncture sessions, with a follow-up visit 4 weeks after therapy. The primary outcome was dyspnea severity as measured using a validated Numerical Rating Scale (NRS) of 0 to 10 (10 being "most severe shortness of breath imaginable"). Results. We enrolled 12 patients in the study. The median age was 64.5 years; 66.7% of the patients were female, and 66.7% were Caucasians. Among those enrolled, 10 (83.3%) were able to complete all 10 acupuncture sessions. Acupuncture was well tolerated; adverse events were mild and self-limited. Mean (SD) dyspnea scores on the NRS improved from 6.3 (1.7) at baseline to 3.6 (1.9; P = .003) at the end of treatment and 3.2 (2.3; P = .008) at follow-up. Fatigue and quality of life also improved significantly with acupuncture (P < .05). Conclusion. Among patients with LC, acupuncture was well tolerated and exhibited promising preliminary beneficial effects in the treatment of dyspnea, fatigue, and quality of life. Performing a trial in this population appears feasible.

Retrospective analysis of bevacizumab-induced hypertension and clinical outcome in patients with colorectal cancer and lung cancer
Abstract
Bevacizumab(Avastin®), a humanized therapeutic monoclonal antibody that targets vascular endothelial growth factor, is widely used in cancer treatment. Patients who are treated with bevacizumab have an increased risk of developing systemic hypertension. However, the relationship between bevacizumab-induced hypertension and clinical outcome remains unclear. We aimed to evaluate the effect of bevacizumab-induced hypertension in terms of prognosis in patients with colorectal cancer and non-small cell lung cancer. The study included 632 patients, 317 patients with non-small cell lung cancer and 315 patients with colorectal cancer. All patients were treated with bevacizumab in combination with standard chemotherapy protocols, between April 2007 and December 2014. Blood pressure was measured before each treatment cycle. In the patient group with colorectal cancer, treated with bevacizumab, Grade 2–3 hypertension was present in 27.6%. In hypertensive patients with colorectal cancer, median overall survival was 42.6 months, compared with 20.6 months for normotensive patients in this group (P = 0.00071). In the patient group with non-small cell lung cancer, treated with bevacizumab, Grade 2–3 hypertension was present in 20.5%. In hypertensive patients with non-small cell lung cancer, median overall survival was 43.0 months, compared with 26.3 months for normotensive patients in this group (P = 0.00451). Patients who developed hypertension during treatment with bevacizumab for colorectal cancer and non-small cell lung cancer had significantly prolonged overall survival when compared with normotensive patients. Bevacizumab-induced hypertension may represent a biomarker for clinical benefit in cancer patients treated with bevacizumab.
The most common bevacizumab-related adverse event was hypertension. Patients who developed hypertension during treatment with bevacizumab for colorectal cancer and non-small lung cancer had significantly prolonged overall survival.

Flow cytometry-based characterization of underlying clonal B and plasma cells in patients with light chain amyloidosis
Abstract
Systemic amyloid light chain (AL) amyloidosis is a life-threatening protein deposition disorder; however, effective therapy can dramatically improve the prognosis of AL patients. Therefore, accurate diagnosis of the underlying hematologic disease is important. Multi-parameter flow cytometry (MFC) is a reliable method to analyze lymphatic neoplasias and to detect even a small lymphatic clone. We analyzed the presence of clonal plasma cell (PC) and B cells in the bone marrow of 63 patients with newly diagnosed AL amyloidosis by MFC. We compared the results with the levels of monoclonal protein, the histopathology and cytogenetic results. As reference of light chain restriction, we used the immunohistochemical results of κ or λ positive amyloid deposits in various tissues. MFC identified underlying clonal lymphatic cells in all but two patients (61 of 63, 97%). Sixty-one patients harbored malignant PCs, whereas B-cell lymphomas were identified in two patients. Furthermore, MFC indicated at least one putative immunotherapeutical target (CD20, CD38, CD52, or SLAMF7) on malignant PCs in all but one patient. These results demonstrate that MFC is a reliable tool for an accurate diagnosis of the underlying hematologic disease and the detection of potential immunotherapeutical targets in patients with AL amyloidosis.

Adherence to cancer screening guidelines in Australian survivors of allogeneic blood and marrow transplantation (BMT)
Abstract
Allogeneic Blood and Marrow Transplant (BMT) survivors are at high risk of secondary cancers. Although current guidelines endorse survivors following Country-specific general population screening recommendations to mitigate this risk, little is known about cancer screening adherence in Australian BMT survivors. We conducted a cross-sectional survey of 441 BMT survivors who were >1 year post transplant, to explore rates of screening for secondary cancers and to identify barriers to cancer screening recommendations. Survey instruments included the Sydney Post-BMT Survey, FACT-BMT, DASS 21, The Chronic Graft versus Host Disease (GVHD) Activity Assessment–Patient Self-Report (Form B), the Lee Chronic GVHD Symptom Scale, Fear of Cancer Recurrence Scale, and The Post Traumatic Growth Inventory. Fifty-seven percent of respondents were male, median age 54 years, and 40% were >6 years post-BMT. Rates of cancer screening adherence were as follows: cervical 63.4%, breast 53.3%, skin 52.4%, and bowel 32.3%. Older BMT survivors and those >2 years post transplant were more likely to undergo cancer screening. Improved quality of life was associated with screening for skin, breast, and cervical cancer. Fear of cancer recurrence negatively impacted on cervical screening. For those who had not undergone screening, the majority reported not being advised to do so by their treatment team. This study is the largest and most comprehensive to date exploring cancer screening adherence in BMT survivors in Australia. These data provide the basis for health service reform to better meet the needs of BMT survivors and provide evidence to support counseling and education of both patients and professionals.

Are parenting behaviors associated with child sleep problems during treatment for acute lymphoblastic leukemia?
Abstract
Sleep disturbance is a recognized common side effect in children treated for acute lymphoblastic leukemia (ALL). Although associated with treatment factors such as hospitalization and corticosteroids, sleep problems may also be influenced by modifiable environmental factors such as parenting behaviors. The purpose of this study was to examine sleep problems in children undergoing treatment for ALL compared to healthy children and whether parenting practices are associated with sleep difficulties. Parents of 73 children aged 2–6 years who were (1) in the maintenance phase of ALL treatment (ALL group, n = 43) or (2) had no major medical illness (healthy control group, n = 30) participated in the study. Parents completed questionnaires measuring their child's sleep behavior and their own parenting practices. Parents of children undergoing ALL treatment reported significantly more child sleep problems; 48% of children with ALL compared to 23% of healthy children had clinical levels of sleep disturbance. Parents of the ALL group also reported significantly more lax parenting practices and strategies associated with their child's sleep including co-sleeping, comforting activities, and offering food and drink in the bedroom. Results of multivariate regression analysis indicated that, after controlling for illness status, parent–child co-sleeping was significantly associated with child sleep difficulties. Strategies employed by parents during ALL treatment may be a potential modifiable intervention target that could result in improved child sleep behaviors. Future research aimed at developing and testing parenting interventions aimed to improve child sleep in the context of oncology treatment is warranted.

Circulating CD14+HLA-DR-/low myeloid-derived suppressor cells in leukemia patients with allogeneic hematopoietic stem cell transplantation: novel clinical potential strategies for the prevention and cellular therapy of graft-versus-host disease
Abstract
Myeloid-derived suppressor cells (MDSCs) are a heterogeneous cell population that includes immature myeloid cells and the progenitor cells of macrophages, dendritic cells (DCs), monocytes, and neutrophils. The expansion and functional importance of MDSCs in patients with cancer and noncancer pathogenic conditions has been recognized. As a result, there has been growing interest in understanding their roles in acute graft-versus-host disease (aGVHD) after allogenetic hematopoietic stem cell transplantation (allo-HSCT). In order to evaluate possible effects of MDSCs on aGVHD development and clinical outcomes, this study systematically detected the dynamic changes of MDSCs accumulation in patients during the first 100 days after allo-HSCT, and investigated the levels of other cell types and relative cytokines during MDSCs accumulation. Results showed that accumulation of MDSCs in the graft and in peripheral blood when engraftment might contribute to patients' overall immune suppression and result in the successful control of severe aGVHD and long-term survival without influence on risk of recurrence after allo-HSCT. But MDSCs levels in the graft had more favorable predictive abilities. Furthermore, MDSCs proportion significantly increased in patients developing aGVHD after allo-HSCT. It might be caused by secondary inflammatory response, especially related to high concentrations of IL-6 and TNF-α. But this accumulation would not be able to counterbalance the aggravation of aGVHD and would not have influence on clinical outcomes and risk of relapse. Overall, MDSCs might be considered as potential new therapeutic option for aGVHD and achieve long-term immunological tolerance and survival.
This study revealed that MDSCs might be considered as a novel prognostic factor in patients with allo-HSCT and potential new approaches to regulate transplant rejection and achieve the recipient host long-term acceptance and survival. The understanding of the activation and differentiation of MDSCs in human will help to develop inhibitors during their unwanted activity, such as preventing relapse, but also provide options for therapeutical intervention in aGVHD after allo-HSCT.

Prognostic microRNA signatures derived from The Cancer Genome Atlas for head and neck squamous cell carcinomas
Abstract
Identification of novel prognostic biomarkers typically requires a large dataset which provides sufficient statistical power for discovery research. To this end, we took advantage of the high-throughput data from The Cancer Genome Atlas (TCGA) to identify a set of prognostic biomarkers in head and neck squamous cell carcinomas (HNSCC) including oropharyngeal squamous cell carcinoma (OPSCC) and other subtypes. In this study, we analyzed miRNA-seq data obtained from TCGA patients to identify prognostic biomarkers for OPSCC. The identified miRNAs were further tested with an independent cohort. miRNA-seq data from TCGA was also analyzed to identify prognostic miRNAs in oral cavity squamous cell carcinoma (OSCC) and laryngeal squamous cell carcinoma (LSCC). Our study identified that miR-193b-3p and miR-455-5p were positively associated with survival, and miR-92a-3p and miR-497-5p were negatively associated with survival in OPSCC. A combined expression signature of these four miRNAs was prognostic of overall survival in OPSCC, and more importantly, this signature was validated in an independent OPSCC cohort. Furthermore, we identified four miRNAs each in OSCC and LSCC that were prognostic of survival, and combined signatures were specific for subtypes of HNSCC. A robust 4-miRNA prognostic signature in OPSCC, as well as prognostic signatures in other subtypes of HNSCC, was developed using sequencing data from TCGA as the primary source. This demonstrates the power of using TCGA as a potential resource to develop prognostic tools for improving individualized patient care.

Phase II evaluation of sunitinib in the treatment of recurrent or refractory high-grade glioma or ependymoma in children: a children's Oncology Group Study ACNS1021
Abstract
Sunitinib malate is a small multi-targeted tyrosine kinase inhibitor that inhibits vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR) and stem cell factor receptor (KIT), which are highly expressed by some high-grade brain tumors. We conducted a phase II study to estimate the efficacy and further characterize the pharmacokinetics of sunitinib in pediatric patients with recurrent or refractory high-grade glioma (Stratum A) or ependymoma (Stratum B). This was a prospective, multicenter Phase II trial conducted through the Children's Oncology Group (ClinicalTrials.gov Identifier NCT01462695). Sunitinib, 15 mg/m2, was orally administered once daily for 4 weeks every 6 weeks. The safety and tolerability of sunitinib, an estimate of progression-free survival (PFS), analyses of sunitinib pharmacokinetics (PK) and pharmacodynamics modulation of plasma VEGF and VEGFR2 were also assessed. Thirty eligible patients (17 patients on Stratum A, 13 patients on Stratum B) were enrolled and 29 patients were evaluable for response. Sunitinib was reasonably well tolerated in children with recurrent ependymoma or high-grade glioma. Most adverse events were of mild-to-moderate severity and manageable with supportive treatment. While there was a statistically significant modulation of plasma VEGFR2 with sunitinib exposure, there were no sustained tumor responses. Both strata were closed at time of planned interim analysis as there was not sufficient efficacy associated with sunitinib in children with recurrent brain tumors. Sunitinib was well tolerated in children and young adults with recurrent high-grade glioma or ependymoma but had no single agent objective antitumor activity in these patients.
This Phase II study of sunitinib reports the safety, tolerability and pharmacokinetic disposition in pediatric patients with recurrent high-grade glioma and ependymoma. While there was sufficient level of sunitinib in peripheral blood to modulate plasma vascular endothelial growth factor receptor (VEGFR)2, there were no sustained responses and no single agent activity in this patient cohort.
