The Rare Disease Bank of Japan: establishment, current status and future challenges

Abstract

Research on rare diseases cannot be performed without appropriate samples from patients with such diseases. Due to the limited number of such patients, securing biosamples of sufficient quality for extensive research is a challenge and represents an important barrier to the advancement of research on rare diseases. To tackle this problem, the Rare Disease Bank (RDB) was established in 2009 at the National Institute of Biomedical Innovation (NIBIO; currently, the National Institutes of Biomedical Innovation, Health and Nutrition in Japan). Since then, the RDB has focused on three objectives: (1) emphasizing the importance of collecting biosamples from patients with rare diseases, together with appropriate clinical information, from various medical facilities nationwide; (2) maintaining strict high-quality sample management standards; and (3) sharing biosamples with research scientists across Japan for the advancement of research on rare diseases. As of August 2017, the bank has collected 4147 biosamples from patients with rare diseases, including DNA, serum, plasma, and cell samples from various university hospitals and other medical institutions across the country, and provided various research institutions with 13,686 biosample aliquots from 2850 cases. In addition, the management committee has successfully established a bank system that provides high-quality biosamples together with the results of human leukocyte antigen analysis. It is anticipated that the RDB, through the collection and sharing of biosamples with the medical research community, will enhance the understanding, prevention, and treatment of rare diseases in Japan and the world at large.

Rechallenge treatment with a platinum-based regimen in patients with sensitive relapsed small-cell lung cancer

Abstract

Among patients with relapsed small-cell lung cancer (SCLC), those who relapse > 90 days after first-line chemotherapy are classified sensitive relapse. Rechallenge with a first-line platinum-based regimen has been used in sensitive relapsed SCLC patients, but its importance is not known. We evaluated the outcome of rechallenge with platinum-based chemotherapy for sensitive relapse patients. We reviewed consecutive patients with sensitive relapsed SCLC who received second-line chemotherapy between January 1999 and December 2016. We evaluated the treatment outcomes of platinum-based rechallenge and non-rechallenge regimens for second-line chemotherapy in sensitive relapse patients. Of 245 patients, 81 sensitive relapse patients received second-line chemotherapy. Sixty-seven patients (82.7%) were treated with rechallenging platinum-based regimens ("rechallenge group") and 14 patients (17.3%) were treated with other regimens ("non-rechallenge group") as second-line chemotherapy. Median progression-free survival (PFS) was 5.1 months in the rechallenge group and 3.5 months in the non-rechallenge group, and median survival time was 10.8 and 8.2 months, respectively. There were no significant differences in PFS or overall survival (OS) between the two groups. Sub-analyses of patients who received chemotherapy alone as first-line treatment showed that the rechallenge group had longer PFS than that of the non-rechallenge group (median 5.4 vs. 3.6 months, p = 0.0038), and the rechallenge group had a tendency to have longer OS than non-rechallenge group. These data suggest that rechallenge treatment with a platinum-based regimen could be second-line chemotherapy in patients with sensitive relapsed SCLC, especially those treated with chemotherapy alone as first-line therapy.

BackgroundExternal ventricular drains (EVDs) are a serious source of morbidity and mortality. Data for interventions proven to reduce risk of infections are lacking. Single-center studies are limited in studying procedures that mitigate infection, but bundled protocols have demonstrated utility. A collaborative EVD registry was designed to facilitate local quality improvement projects to be implemented at any location using standardized data collection instruments through resident collaboration to reduce and study EVD infection and prevention.MethodsA bundled protocol and comprehensive implementation program were developed as a quality improvement project to reduce ventriculostomy-associated infections. Standardized data collection forms were created for multi-institutional participation in an EVD registry. Retrospective and prospective patient data were documented in an electronic procedural registry, which was designed to capture variation among multiple institutions.ResultsTwo infections were found in 1924 EVD-days before protocol implementation; no infections were found in 700 EVD-days after protocol implementation. Baseline epidemiology of EVDs was calculated in preparation for comparison. A resident-driven EVD consortium, now with 5 other member institutions, was founded to collect data for an EVD registry fed by individual site quality improvement initiatives.ConclusionsThe ventriculostomy-associated infection rate at the University of Minnesota is low compared with the literature. Rationally bundled protocols have mounting evidence but do not allow for identifying effective individual components. Through the registry described here, others can join the EVD consortium to contribute data to facilitate comparative effectiveness research with minimal investment.

Author(s): Marcelo D. Vilela, Uedson Tazinaffo
Various mixed associations between arteriovenous malformations, cavernous malformations, developmental venous anomalies, and capillary telangiectasias have been described, and a common pathophysiologic event has been suggested to be present, although it is yet to be elucidated. We depict herein the imaging features of a patient who presented with a spontaneous cerebellar hemorrhage, in whom radiologic studies demonstrated a pontine telangiectasia, a brainstem/cerebellar developmental venous anomaly, and a cerebellar proliferative angiopathy. This unique, not previously reported combination of lesions shows that the spectrum of mixed vascular malformations continues to expand. A pathophysiologic mechanism related to the angiogenesis seen in these malformations is also hypothesized.

Author(s): James K.C. Liu
BackgroundIntracranial hypotension from cerebrospinal fluid (CSF) hypovolemia resulting in cerebral herniation is a rare but known complication that can occur after neurosurgical procedures, usually encountered in correlation with perioperative placement of a lumbar subarachnoid drain. Decrease in CSF volume resulting in loss of buoyancy results in downward herniation of the brain without contributing mass effect, causing a phenomenon known as brain sag. Unreported previously is brain sag occurring without concomitant occult CSF leak or lumbar drainage.Case DescriptionThis case report describes a patient who underwent bilateral craniotomies for subacute on chronic subdural hematoma with successful decompression but experienced acute neurologic deterioration secondary to brain sag. Despite an initial improvement in neurologic function, he subsequently experienced progressive neurologic deterioration with evidence of cerebral herniation on neuroimaging, without evidence of continued mass effect on the brain parenchyma. After a diagnosis of brain sag was determined based on imaging criteria, the patient was placed in a flat position, which resulted in rapid improvement in his neurologic function without any further intervention.ConclusionsThis case is unique in comparison with previous reports of intracranial hypotension after craniotomy in that the symptoms were completely reversed with positioning alone, without any evidence of active or occult CSF drainage. This report emphasizes that the diagnosis of brain sag should be taken into consideration when there is an unknown reason for neurologic decline after craniotomy, particularly bilateral craniotomies, if the imaging indicates herniation with imaging findings consistent with intracranial hypotension, without evidence of overlying mass effect.

BackgroundAberrant medial retropharyngeal prevertebral course of the internal carotid arteries (ICAs) is extremely uncommon. In oropharyngeal surgeries, like transoral odontoidectomy (TOO), this unrecognized aberrant retropharyngeal course of ICAs can result in devastating complications secondary to inadvertent injury of ICAs. We describe this aberrant course of ICAs in a patient with a craniovertebral junction (CVJ) anomaly with a dysmorphic C1 lateral mass on one side and discuss in detail various management issues in this complex case.Case DescriptionA 44-year-old patient presented with neck pain, paresthesia in all 4 limbs, and quadriparesis. Computed tomography (CT) of the CVJ revealed os odontoideum, basilar invagination, atlantoaxial dislocation (AAD), severe malalignment of the C1–C2 facets, and an unusually thin (dysmorphic) left C1 lateral mass. Computed tomographic angiography revealed an aberrant medial retropharyngeal course of the bilateral cervical ICAs with near midline location at the level of C1 and C2. Transoral odontoidectomy (TOO) was not considered safe in view of potential injury to medially located ICAs. Normal spinal alignment with reduction of BI and AAD was achieved by C1–C2 joint distraction with placement of a spacer only in the right C1–C2 joint space followed by occipitocervical fusion. The patient experienced complete recovery after surgery with improvement of power in all 4 limbs to 5/5.ConclusionsIdentification of this rare aberrant prevertebral course of ICAs in a patient with a CVJ anomaly is critical because it precludes TOO as a treatment option. Correction of BI and AAD is possible even with a unilateral C1–C2 joint spacer when placement of a joint spacer on the other side is not technically feasible.

Author(s): Tomoo Inoue, Yukoh Ohara, Tadaaki Niiro, Toshiki Endo, Teiji Tominaga, Jyun-ichi Mizuno
BackgroundChondroma is a rare benign cartilaginous tumor that originates in chondrocytes and is commonly seen in the long bones; however, it infrequently occurs in the cervical spine.Case DescriptionsWe report 2 patients with cervical periosteal chondroma that originated in the C2 vertebral body and C1 lamina as extramedullary tumors. The first patient was a 28-year-old man who presented with right upper extremity weakness and numbness. Cervical radiography revealed a bony tumor with evidence of severe spinal cord compression. The second patient was a 26-year-old woman with left occipital neuralgia. Cervical radiography demonstrated a bony tumor arising from the left C1 lateral mass that compressed the C2 nerve root. Both patients underwent surgical removal of the bony tumors, which were diagnosed as periosteal chondroma.ConclusionsThe authors herein summarized 16 previous reports of cervical chondroma and compared the clinical courses and treatments. Recommended treatment included maximal surgical resection, especially when significant compression of the cervical cord and signal abnormality within the cord was observed. Annual postoperative follow-up is mandatory to ensure proper neurologic improvement.

Sterilized talc pleurodesis for malignant pleural effusions: a Phase II study for investigational new drug application in Japan

Abstract
Background
Malignant pleural effusion is a commonly seen complication of malignancies such as lung and breast cancers. In Western countries, talc is frequently used as a standard therapeutic agent (pleurodesis agent) with the aim of alleviating symptoms including dyspnea and chest pain. Talc is not recognized as a pleurodesis agent in Japan. The aim of this study was to verify the efficacy and safety of sterilized talc (NPC-05) for the introduction of talc in Japan.
Methods
The study was a single-arm, open-label, investigator-initiated trial conducted jointly at six institutions. The subjects were 30 patients with malignant pleural effusions. A solution of 4 g NPC-05 suspended in 50 ml physiological saline was instilled into the pleural space to perform pleurodesis.
Results
The efficacy of NPC-05 for pleural adhesion 30 days after pleurodesis was 83.3% (25/30 cases). Amelioration of dyspnea and pain (chest pain) was seen. Commonly seen adverse effects were increased C-reactive protein (CRP) and fever. Nearly all adverse events were phenomena previously reported as adverse effects of talc. No acute respiratory distress syndrome (ARDS) or other serious side effects occurred.
Conclusion
The efficacy and safety of NPC-05 for malignant pleural effusion in Japanese patients was verified, and the clinical outcomes with talc were confirmed to be the same as previously reported in other countries. There is thought to be a high level of need for this agent in the treatment of malignant pleural effusion in Japan.

Preoperative prognostic nutritional index as a predictor of outcomes in elderly patients after surgery for lung cancer

Abstract
Background and objective
The prognostic nutritional index (PNI) is based on the serum albumin level and lymphocyte count, and is a useful predictor of survival in various cancers. However, the utility of PNI in lung cancer has not been examined. The aim of this study is to assess PNI as a prognostic factor in elderly patients after surgery for primary lung cancer.
Methods
A retrospective review was performed in 131 elderly patients (≥75 years old) with lung cancer who underwent curative operations at our hospital from July 2008 to December 2014. Survival was calculated by the Kaplan–Meier method. The effects of PNI and clinicopathological factors on survival were evaluated in univariate and multivariate Cox regression analyses.
Results
The 5-year cancer-specific survival (CSS) rates of patients with PNI ≥ 45 and <45 were 76.2% and 47.8%, respectively (P = 0.0166), and the 5-year overall survival (OS) rates were 61.9% and 39.8%, respectively (P = 0.0275). Among patients who died within 5 years, mortality due to other diseases was 31%. Univariate analysis identified gender (P = 0.003), serum carcinoembryonic antigen (CEA) (P = 0.009), PNI (P = 0.027), c-stage (P = 0.005), histological type (P = 0.001) and p-stage (P < 0.001) as prognostic factors. In multivariate analysis, CEA (HR 2.487, P = 0.0169), PNI (HR 2.737, P = 0.0289) and p-stage (HR 3.294, P = 0.007) were independent prognostic factors in elderly patients after curative surgery for lung cancer.
Conclusions
CEA, PNI and p-stage are independent prognostic factors in elderly patients after surgery for primary lung cancer. Therefore, determination of preoperative PNI may be useful for treatment planning in elderly patients with lung cancer.

Poor oral intake causes enteral nutrition dependency after concomitant chemoradiotherapy for pharyngeal cancers

Abstract

Purpose

To identify precipitating factors responsible for enteral nutrition (EN) dependency after concomitant chemoradiotherapy (CCRT) of head and neck cancers and to examine their statistical correlations.

Methods

Factors related to feeding condition, nutritional status, disease, and treatment of 26 oropharyngeal and hypopharyngeal cancer patients who received definitive CCRT were retrospectively investigated by examining their medical records. The days of no oral intake (NOI) during hospitalization and the months using enteral nutrition after CCRT were counted as representing the feeding condition, and the changes in body weight (BW) were examined as reflecting nutritional status. The factors related to EN dependency after CCRT were analyzed.

Results

Long duration of total NOI (≥ 30 days) and maximum NOI ≥ 14 days were significant predictors of EN dependency. Decreased BW (≥ 7.5 kg) was the next predictor identified, but it was not significant. Multivariate analysis showed that the total duration of NOI was more correlated with EN dependency than changes in BW.

Conclusions

A long duration of NOI was more strongly related to EN dependency than nutritional factors.

Imaging evaluation of electrode placement and effect on electrode discrimination on different cochlear implant electrode arrays

Abstract

Objective

The aim of the present study is to evaluate the effect of electrode discrimination based on electrode to modiolus distance in different cochlear implant models, using image information to estimate the outcomes after an implantation on electrode discrimination

Methods

A descriptive prospective randomized study performed during 16 months. A psychoacoustic platform was used to evaluate patients' electrode discrimination capabilities of patients. For the acquisition of the images, a cone beam computed tomography was used to assess postcochlear implantation of electrodes' position. We considered two other new measurements: the intracochlear position index, which indicates how far is the electrode from the modiolar wall, and the homogeneity factor (HF), which provides us with information about the distance between the electrodes and the modiolus

Results

21 postlingually deaf adults showing different CI models [CI522 (n = 7), CI512 (n = 7), and CI532 (n = 7)] that corresponded to the lateral and perimodiolar array electrodes. The average success rate of the CI522 group was 47%, of the CI512 group was 48%, and of the CI532 group was 77%. There is statistically significant difference between groups CI532–CI522 (p = 0.0033) and CI532–CI512 (p = 0.0027)

Conclusion

The Nucleus CI532 offers a better perimodiolar placement. HF and IPI measurements provide information about the electrodes location inside the cochlea, being related to electrode discrimination.

What parents are reading about laryngomalacia: Quality and readability of internet resources on laryngomalacia.

Int J Pediatr Otorhinolaryngol. 2018 May;108:175-179

Authors: Corredera E, Davis KS, Simons JP, Jabbour N

Abstract
OBJECTIVE: The goal of this study is to measure the quality and readability of websites related to laryngomalacia, and to compare the quality and readability scores for the sites accessed through the most popular search engines.
INTRODUCTION: Laryngomalacia is a common diagnosis in children but is often difficult for parents to comprehend. As information available on the internet is unregulated, the quality and readability of this information may vary.
METHODS: An advanced search on Google, Yahoo, and Bing was conducted using the terms "laryngomalacia" OR "soft larynx" OR "floppy voice box." The first ten websites meeting inclusion and exclusion criteria were evaluated, for each search engine. Quality and readability were assessed using the DISCERN criteria and the Flesch reading ease scoring (FRES) and Flesch-Kincaid grade level (FKGL) tests, respectively.
RESULTS: The top 10 hits on each search engine yielded 15 unique web pages. The median DISCERN score (out of a possible high-score of 80) was 48.5 (SD 12.6). The median USA grade-level estimated by the FKGL was 11.3 (SD 1.4). Only one website (6.7%), had a readability score in the optimal range of 6th to 8th grade reading level. DISCERN scores did not correlate with FKGL scores (r = 0.10).
CONCLUSION: Online information discussing laryngomalacia often varies in quality and may not be easily comprehensible to the public. It is important for healthcare professionals to understand the quality of health information accessible to patients as it may influence medical decision-making by patient families.

Extrinsic and Intrinsic Apoptotic Responses Induced by Shiitake Culinary-Medicinal Mushroom Lentinus edodes (Agaricomycetes) Aqueous Extract against a Larynx Carcinoma Cell Line.

Extrinsic and Intrinsic Apoptotic Responses Induced by Shiitake Culinary-Medicinal Mushroom Lentinus edodes (Agaricomycetes) Aqueous Extract against a Larynx Carcinoma Cell Line.

Int J Med Mushrooms. 2018;20(1):31-46

Authors: Finimundy TC, Scola G, Scariot FJ, Dillon AJP, Moura S, Echeverrigaray S, Henriques JP, Roesch-Ely M

Abstract
Cumulative evidence from research studies has shown that the shiitake culinary-medicinal mushroom, Lentinus edodes, is an excellent source of natural antitumor agents and is capable of inhibiting cancer cell growth. However, the cell signaling pathway that leads tumor cells to apoptosis is not well understood because many chemical compounds may be acting. This study investigated the chemopreventive effects of an L. edodes aqueous extract on human HEp-2 epithelial larynx carcinoma cells and normal human MRC-5 lung fibroblasts by identifying proliferative and apoptotic pathways. The chemical characterization of the dry powder was assessed by high-performance liquid chromatography. Antiproliferative and proapoptotic effects induced by the extract were evaluated by assessing proliferative markers, cell sorting through flow cytometry, and expression levels of apoptotic proteins with Western blotting. The results suggest that inhibition of cell proliferation was more prominent in HEp-2 than in MRC-5 cells. Cell death analysis showed the appearance of cell populations in the sub-G1 phase, with late apoptotic signal increased in a dose-dependent manner. In addition, the aqueous extract induced depolarization of mitochondria, activating the generation of intracellular reactive oxygen species in HEp-2 cells. These observations suggest that L. edodes extract may exert a chemopreventive effect, regulating mitotic induction of apoptogenic signals. These findings highlight the mushroom's pharmacological potential in cancer treatment.

Endoscopic percutaneous suture lateralization for neonatal bilateral vocal fold immobility.

Endoscopic percutaneous suture lateralization for neonatal bilateral vocal fold immobility.

Int J Pediatr Otorhinolaryngol. 2018 May;108:120-124

Authors: Montague GL, Bly RA, Nadaraja GS, Conrad DE, Parikh SR, Chan DK

Abstract
OBJECTIVE: Bilateral vocal-fold immobility (BFVI) is a rare but significant cause of severe respiratory distress in neonates. The primary aim of treatment is to provide an adequate airway while minimizing adverse effects such as aspiration and dysphonia. Our objective here is to describe the outcomes of a series of neonates undergoing percutaneous endoscopic suture lateralization for BVFI using a novel technique.
METHODS: In this retrospective case series, we present 6 neonates (mean age: 18 days) with BVFI from three tertiary academic medical centers. The etiologies included 4 idiopathic, 1 unspecified neurodegenerative disorder, and 1 acquired from cardiac surgery. All had stridor and respiratory distress with hypoxemia requiring respiratory support at diagnosis. Endoscopic vocal-fold lateralization was performed under spontaneous-breathing suspension laryngoscopy using a novel technique of percutaneous needle-directed placement of 4-0 prolene suture without use of specialized equipment.
RESULTS: All patients had clinical improvement in stridor and respiratory support requirements and avoided tracheostomy. One patient had persistent aspiration after lateralization that resolved after suture removal. One patient required bilateral lateralization procedures. One patient expired of epilepsy due to neurodegenerative disease unrelated to airway pathology. At last follow-up (mean 12.6 months), 5/5 remaining patients were on room air without tracheostomy and feeding orally without aspiration; 4/5 had partial or complete return of vocal-fold function.
CONCLUSION: Endoscopic percutaneous suture lateralization may be a safe and effective non-destructive primary treatment modality for neonatal BVFI. All neonates undergoing this procedure avoided tracheotomy.

The Role of FIESTA MRI for Assessment of Delayed Enhancement of Fat Graft Packing on Post-Operative Imaging After Vestibular Schwannoma Surgery.

World Neurosurg. 2018 Mar 29;:

Authors: Kamal N, Reddy R, Kohli G, Lee HJ, Mary Ying YL, Jyung RW, Liu JK

Abstract
OBJECT: This study investigates the role and efficacy of FIESTA imaging in distinguishing fat graft enhancement from residual or recurrent tumor after vestibular schwannoma (VS) surgery.
METHODS: A retrospective study of 33 patients who underwent VS resection via the retrosigmoid or translabyrinthine approach with fat graft reconstruction was performed. MR images were collected at different time points: preoperative, immediate postoperative (24-48 hours), delayed postoperative (3-6 months after surgery), and yearly postoperative. The image sets contained T1, T2, Fat Suppressed T1-weighted with Gadolinium, and FIESTA. The radiographs were analyzed for tumor recurrence by the primary neurosurgeon and an independent blinded neuroradiologist. If fat suppressed T1-weighted images demonstrated postoperative enhancement in the resection bed, a comparison was made with FIESTA imaging.
RESULTS: At 3-6 months postoperatively and at 1 year and beyond, 28 (84.8%) and 33 (100%) of patients, respectively, displayed delayed enhancement of the fat graft on post-gadolinium fat-suppressed T1 MRI. The enhancement seen on post-gadolinium fat-suppressed T1-weighted MRI consistently correlated with the characteristic fat graft signal on FIESTA imaging and not tumor recurrence. FIESTA imaging was able to distinguish residual tumor from enhancing fat graft compared to post-gadolinium fat-suppressed T1-weighted MR images (p<0.0001) due to distinctive signaling patterns.
CONCLUSION: FIESTA is an effective tool in discerning fat graft enhancement from residual or recurrent tumor on delayed postoperative imaging after VS resection. Fat graft used in reconstruction consistently enhances on delayed postoperative post-gadolinium fat suppressed T1-weighted imaging, which correlates with the fat graft signal seen on FIESTA images.

Authors: Daneshi A, Mirsalehi M, Hashemi SB, Ajalloueyan M, Rajati M, Ghasemi MM, Emamdjomeh H, Asghari A, Mohammadi S, Mohseni M, Mohebbi S, Farhadi M

Abstract
OBJECTIVES: To evaluate the auditory performance and speech production outcome in children with auditory neuropathy spectrum disorder (ANSD). The effect of age on the outcomes of the surgery at the time of implantation was also evaluated.
METHODS: Cochlear implantation was performed in 136 children with bilateral severe-to- profound hearing loss due to ANSD, at four tertiary academic centers. The patients were divided into two groups based on the age at the time of implantation; Group I: Children ≤24 months, and Group II: subjects >24 months. The categories of auditory performance (CAP) and speech intelligibility rating (SIR) scores were evaluated after the first and second years of implantation. The differences between the CAP and SIR scores in the two groups were assessed.
RESULTS: The median CAP scores improved significantly after the cochlear implantation in all the patients (p value < 0.001). The improvement in the CAP scores during the first year in Group II was greater than Group I (p value: 0.007), but the improvement in CAP scores tended to be significantly higher in patients who were implanted at ≤24 months (p value < 0.001). There was no significant difference between two groups in SIR scores at first-year and second-year follow-ups. The evaluation of the SIR improvement revealed significantly higher values for Group I during the second-year follow-up (p value: 0.003).
CONCLUSION: The auditory performance and speech production skills of the children with ANSD improved significantly after cochlear implantation, and this improvement was affected by age at the time of implantation.

Potassium titanyl phosphate laser-induced inflammatory response and extracellular matrix turnover in rabbit vocal fold scar

Abstract

Purpose

The objectives of this study were to observe the regulating effect of KTP laser and Nd:YAG laser in the repair of vocal fold scars.

Methods

All rabbits were injured in the muscular layer with a sharp instrument, and then the vocal folds were treated with a KTP laser and a Nd:YAG laser at a power of 2, 4, 6 and 8 W 1 month after the injury. One month after treatment, the rabbits were killed and the throats were removed to detect changes in histology and gene expression of the vocal fold scar after laser therapy.

Results

The best efficacy of all KTP laser treatment groups was the KTP laser 6 W group. Regarding the detection of gene expression, in the KTP laser 6 W and Nd:YAG laser 6 W groups, col-3A1 was decreased compared to the scar group (P < 0.05), and col-1A1 was decreased only in the KTP laser 6 W group (P < 0.05). TGF-β1 levels in the two groups were lower than in the scar group. There were also significant differences in the levels of IL-1β, COX-2 and TNF-α in the two laser groups compared with the scar group (P < 0.05).

Conclusion

KTP laser and Nd:YAG laser treatments for vocal fold scars have particular therapeutic effects. The KTP laser may be better than the Nd:YAG laser for the regulation of vocal fold scars.

Level of evidence

NA.

Organ preservation surgery for patients with T4a laryngeal cancer

Abstract

Purpose

Surgical preservation of laryngeal function is very challenging in patients with advanced SCCL, especially those of stage T4a. The purpose of this study was to assess the feasibility of organ preservation surgery for patients with T4a squamous cell carcinoma of the larynx (SCCL).

Methods

We enrolled 32 patients with T4a SCCL and performed organ preservation surgery on them. Surgical details and perioperative morbidity were described, functional and oncologic outcomes were also evaluated.

Results

All patients underwent supracricoid subtotal laryngectomy with unilateral or bilateral neck dissection, restoring laryngeal function via direct anastomosis of the cricoid cartilage and tongue base. The patients recovered well and exhibited relatively acceptable survival duration, with a 5-year overall survival rate of 62.5%. Most patients commenced oral intake within 2 weeks, and aspiration was commonly observed. Subjective functional outcomes indicated a relatively acceptable swallowing function and voice quality.

Conclusion

Our retrospective analysis of 32 patients with T4a SCCL showed that successful organ preservation surgery is safe and reliable, and associated with a relatively acceptable disease-free survival, normal swallowing function, and acceptable voice quality. More patients with T4a SCCL who wish to preserve the larynx should be considered for organ preservation surgery.

Effects of gadolinium-based contrast agents on submandibular gland tissue in rats.

Effects of gadolinium-based contrast agents on submandibular gland tissue in rats.

Eur Arch Otorhinolaryngol. 2018 Mar 31;:

Authors: Celiker FB, Tumkaya L, Yilmaz A, Coskun ZO, Celiker M, Oghan F, Mercantepe T, Terzi S, Dursun E

Abstract
AIM: The aim of this prospective animal study is to investigate the influence of multiple administrations of macrocyclic ionic (gadoteric acid) and linear nonionic (gadodiamide) gadolinium-based contrast agents (GBCA) on submandibular gland tissue (SGT) of the rats.
MATERIAL AND METHOD: Twenty-four Sprague Dawley female rats were included the study. Group 1 was determined as a control group (n = 6). Group 2 was determined as saline group (n = 6). Group 3 was determined as Omniscan group (n = 6) and received only intraperitoneal (IP) 0.1 mmol (0.2 mL/kg)/kg gadodiamide for 8 days. Group 4 was determined as Dotarem group (n = 6) and received only IP 0.1 mmol (0.2 mL/kg)/mg/kg gadoteric acid daily for 8 days. On the 9th day of the administration, the rats were sedated with ketamine and xylazine through IP injection. The right SGT was removed after sedation. Histopathological and immunohistochemical changes in SGT were evaluated.
RESULTS: The SGT of the Omniscan and Dotarem groups decreased SGT acini surface area, and serous acinar cells number were observed. On the other hand, no pathology was observed. Mucous acinar cells' caspase-3 positivity for the same markers in Omniscan and Dotarem sections was similar to the control group. However, Omniscan and Dotarem groups serous acinar cells were caspase-3 (+) staining. The intensity of serous acinar cells' caspase-3 (+) for the same markers in Dotarem sections was similar to the Omniscan group. The results also revealed in the analysis of the mean area of the acinus area of the SGT; there were significantly decreased Dotarem group rats when compared to control rats (p < 0.05).
CONCLUSION: We consider that numerical increased apoptosis results arise from repeated doses of GBCAs. Being aware of this effect of the contrast agent may have significance for the chronic sialo-adenitis patients group when used for recurrent contrasted MRI for diagnosis of diseases like MS which requires in follow-up. We should be aware about the frequently contrasted MRI in routine investigations.

Intratympanic steroid use for idiopathic sudden sensorineural hearing loss: current otolaryngology practice in Germany and Austria.

Intratympanic steroid use for idiopathic sudden sensorineural hearing loss: current otolaryngology practice in Germany and Austria.

Eur Arch Otorhinolaryngol. 2018 Mar 31;:

Authors: Sutton L, Schartinger V, Url C, Schmutzhard J, Lechner D, Kavasogullari C, Sandhu JS, Shaida A, Laszig R, Loehler J, Plontke S, Riechelmann H, Lechner M

Abstract
AIMS: The frequency of the use of intratympanic steroids (ITS) as a treatment for idiopathic sudden sensorineural hearing loss (ISSNHL) in Europe is still unknown and remains a contentious issue amongst otolaryngologists. We undertook a survey of otolaryngologists in Germany and Austria to establish if there is any professional consensus with which to form a protocol for its use.
METHODS: A survey of 21 questions was distributed electronically to otolaryngologists in Germany and Austria and data on demographics, indications for intratympanic treatment, procedure, follow-up, and outcomes were analysed.
RESULTS: We received 908 responses. 49.1% of otolaryngologists used ITS for ISSNHL. Of those otolaryngologists who use ITS, 73.7% do not use it as primary treatment. 20.6% use ITS in conjunction with oral steroids for primary treatment and only 5.8% use ITS as monotherapy for primary treatment. 90.5% use ITS as salvage therapy. 81.1% do not consider the use of ITS after 2 weeks from the onset of symptoms. 8.3% used a tympanostomy tube and while the most commonly used steroid was dexamethasone at a concentration of 4 mg/ml (61%), a wide variety or other steroids and concentrations were used.
CONCLUSIONS: This survey illustrates wide variation of current practice of intratympanic corticosteroid injection for ISSHL in Germany and Austria. In the absence of high-level evidence, knowing what current practice is allows clinicians to assess what they do against what their colleagues are doing, and if they do something very different, make them question their practice. Moreover, the obtained data will help to direct future clinical trials with the aim to compare the outcomes of more commonly used protocols.

Tailored strategies to manage cerebrospinal fluid leaks or pseudomeningocele post-surgery for tethered cord syndrome.

Tailored strategies to manage cerebrospinal fluid leaks or pseudomeningocele post-surgery for tethered cord syndrome.

World Neurosurg. 2018 Mar 29;:

Authors: Udayakumaran S, Rathod CT

Abstract
BACKGROUND: Cerebrospinal fluid (CSF) leaks are a dreaded complication after surgery for tethered cord and are associated with significant patient morbidity. Although many strategies for managing postoperative CSF leaks exist, this problem is still daunting, especially in the very young patients. In this article, the authors compared different management techniques for CSF leaks or significant pseudomeningocele in patients with tethered cord syndrome (TCS).
METHODS: We analysed a cohort of children who underwent surgery for TCS from January 2011 to March 2016 (n = 260) and postoperatively experienced either a CSF leak or significant pseudomeningocele. A subset of patients presented with CSF leak (n = 25). We analysed patient age, sex, presentation, leak appearance, management, and outcome. The different techniques of management were compared for efficacy and morbidity.
RESULTS: The pathologies associated with leak formation included lipomyelomeningocele (n = 16), myelocystocele (n = 4), and myelomeningocele (n = 5). Three children also had hydrocephalus. Management techniques included cystperitoneal shunt (CPS;n = 15), primary re-suturing with local rotation flap of muscle (n = 3), external ventricular drain placement (n = 1), ventriculoperitoneal shunt (VPS; n = 3), external ventricular drainage (n = 1), and a combination of techniques (rotation flap with external drain; n = 1). Five patients who underwent primary wound revision experienced a leak and required a secondary intervention, but none of the patients who underwent CPS had any complications.
CONCLUSIONS: In carefully selected cases, CPS performed early after CSF leakage is highly successful with low morbidity. The primary closure can be attempted for low-pressure leaks without an associated pseudomeningocele.

Robotic sleeve resection for pulmonary disease

Abstract

Background

Few studies have described robotic sleeve resection with pulmonary resection. Here, we report the successful implementation of a completely portal robotic sleeve resection with or without pulmonary resection using a modified suture mode.

Methods

In total, 339 patients underwent curative robotic pulmonary surgery at Ruijin Hospital between May 2015 and September 2017. Three of these patients underwent robotic sleeve resection (right upper lobe, one; left upper lobe, one; and lingular segmental bronchus, one). Five port incisions were utilized, and a simple continuous running suture combined with two interrupted sutures of the membranous and cartilaginous junction portion was preferred for the anastomosis.

Results

The postoperative course was uneventful for two patients with squamous cell carcinoma. The lingular segmental bronchus patient without pulmonary resection (a salivary gland tumor) underwent short-term atelectasis. The median operation time was 155 (range 132–230) minutes. The median anastomosis time was 25 (range 23–32) minutes. The median length of postoperative hospital stay was 7 (range 6–10) days. There was no mortality or conversion to thoracotomy for any of the patients. All patients were followed for 3–6 months, and there is no tumour recurrence.

Conclusions

Our limited experience suggested that robotic sleeve resection for pulmonary disease with or without pulmonary resection may be safe and effective. The anastomosis time can be shortened with more robotic surgery experiences and the modified suture mode.

The use of gait analysis in the assessment of patients afflicted with spinal disorders

Abstract

Purpose

Use gait analysis to establish and detail the clinically relevant components of normal human gait, analyze the gait characteristics for those afflicted with spinal pathology, and identify those aspects of human gait that correlate with pre- and postoperative patient function and outcomes.

Methods

Twenty patients with adult degenerative scoliosis (ADS), 20 patients with cervical spondylotic myelopathy (CSM), and 15 healthy volunteers performed over-ground gait trials with a comfortable self-selected speed using video cameras to measure patient motion, surface electromyography (EMG) to record muscle activity, and force plates to record ground reaction force (GRF). Gait distance and temporal parameters, ankle, knee, hip, pelvic, and trunk range of motion (ROM), duration of lower extremity EMG activity and peak vertical GRF were measured.

Results

Patients with ADS and CSM exhibited a significantly slower gait speed, decrease in step length, cadence, longer stride time, stance time, double support time, and an increase in step width compared to those in the control group. These patients also exhibited a significantly different ankle, knee, pelvic, and trunk ROM. Moreover, spinal disorder patients exhibited a significantly longer duration of rectus femoris, semitendinosus, tibialis anterior and medial gastrocnemius muscle activity along with an altered vertical GRF pattern.

Conclusions

Gait analysis provides an objective measure of functional gait in healthy controls as well as those with ADS and CSM. This study established and detailed some of the important kinematic and kinetic variables of gait in patients with spinal disorders. We recommend that spine care providers use gait analysis as part of their clinical evaluation to provide an objective measure of function.

Psychometric validation of the cross-culturally adapted traditional Chinese version of the Back Beliefs Questionnaire (BBQ) and Fear-Avoidance Beliefs Questionnaire (FABQ)

Abstract

Purpose

To translate and cross-culturally adapt the Back Beliefs Questionnaire (BBQ) and Fear-Avoidance Beliefs Questionnaire (FABQ) into traditional Chinese for their use in patients experiencing low back pain (LBP).

Methods

This was a prospective questionnaire translation and psychometric validation of the BBQ and FABQ in Chinese patients with back pain. Patients also completed the Traditional Chinese (Hong Kong) versions of the Oswestry Disability Index (ODI), the Short Form-12 version 2 (SF-12v2) questionnaires and the visual analogue scale (VAS) for LBP. Construct validity was assessed using Spearman's correlation test against the subscales and domains with similar constructs. Internal consistency was assessed by Cronbach's alpha (α). Sensitivity was determined by known-group comparisons.

Results

A total of 100 patients were recruited. Both BBQ (α = 0.810) and FABQ (α = 0.859) demonstrated excellent overall internal consistency. BBQ scores significantly correlated with ODI scores, VAS-LBP and all domains of SF-12v2 (p < 0.01–0.05), whereas only FABQ Work subscale correlated with ODI scores (p < 0.01) and VAS-LBP (p < 0.05). Both FABQ subscales correlated with only specific domains of SF-12v2 (p < 0.01–0.05). FABQ-W was sensitive to difference between patients with acute versus chronic back pain.

Conclusions

Both the adapted BBQ and FABQ (Traditional Chinese-Hong Kong) were demonstrated to have satisfactory psychometric properties, with adequate internal consistencies, construct validity and sensitivity to certain clinical parameters. Our findings were based on a clinically relevant patient group and provides insight into patients' own perception of back pain which may often be different from that of surgeons. This is a platform for future cross-cultural comparisons.

Organics Wastewater Degradation by a Mesoporous Chromium-Functionalized γ-Al 2 O 3 with H 2 O 2 Assistance

Abstract

In this study, a mesoporous chromium-functionalized γ-Al2O3 (Cr/γ-Al2O3) catalyst was prepared by an impregnation method, and the catalytic activity was evaluated by the degradation of organics wastewater. The prepared catalyst was characterized by X-ray photoelectron spectroscopy, X-ray diffraction, nitrogen adsorption-desorption experiments, and scanning electron microscopy. The characterization results confirmed that the pores in the Cr/γ-Al2O3 catalyst distributed broadly in the mesoporous region, and the active chromium species were highly dispersed on the catalyst surface. The catalytic activity tests showed that the Cr/γ-Al2O3 catalyst exhibited a superior performance for the degradation of organics wastewater with H2O2 assistance. And the methylene blue (MB) disappeared within 20 min and the COD removal reached 76.5% within 40 min for the MB-simulated wastewater; for the phenol-simulated wastewater, the phenol removal was above 95% and the corresponding COD removal reached 71% within 40 min. Such an excellent catalytic performance demonstrates that the Cr/γ-Al2O3 catalyst has a potential application in the degradation of complex organics wastewater simultaneously.

Platform trials arrive on time for glioblastoma

The German National Center for Tumor Diseases (NCT) has developed a noncomparative screening trial called Neuro Master Match (N2M2) for first-line unmethylated glioblastoma (GBM) patients.1 In the current issue of Neuro-Oncology, the NCT presents pilot data to evaluate feasibility and timeliness of performing complex multilayer molecular diagnostics in a clinical setting to support N2M2. These data are timely in our field, as many platform trials are either ongoing2 or planned3 where biomarker data are important for patient allocation. We will first provide a bit more depth on N2M2 and then compare and contrast this trial with 2 other platform trials: the INdividualized Screening trial of Innovative GBM Therapy (INSIGhT)2 and the GBM Adaptive Global Innovative Learning Environment (GBM AGILE).3

No association between circulating concentrations of vitamin D and risk of lung cancer: An analysis in 20 prospective studies in the Lung Cancer Cohort Consortium (LC3)

Abstract
Background
There is observational evidence suggesting that high vitamin D concentrations may protect against lung cancer. To investigate this hypothesis in detail, we measured circulating vitamin D concentrations in pre-diagnostic blood from 20 cohorts participating in the Lung Cancer Cohort Consortium (LC3).
Patients and methods
The study included 5,313 lung cancer cases and 5,313 controls selected from. Blood samples for the cases were collected, on average, 5 years prior to lung cancer diagnosis. Controls were individually matched to the cases by cohort, sex, age, race/ethnicity, date of blood collection, and smoking status in 5 categories. Liquid chromatography coupled with tandem mass spectrometry was used to separately analyze 25-hydroxyvitamin D2 (25(OH)D2) and 25-hydroxyvitamin D3 (25(OH)D3) and their concentrations were combined to give an overall measure of 25(OH)D. We used conditional logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI) for 25(OH)D as both a continuous and categorical variable.
Results
Overall, no apparent association between 25(OH)D and risk of lung cancer was observed (multivariable adjusted OR for a doubling in concentration: 0.98, 95% confidence interval: 0.91, 1.06). Similarly, we found no clear evidence of interaction by cohort, sex, age, smoking status, or histology.
Conclusion
This study did not support an association between vitamin D concentrations and lung cancer risk.

Myeloma Cells Are Activated in Bone Marrow Microenvironment by the CD180/MD-1 Complex, Which Senses Lipopolysaccharide

Multiple myeloma (MM) cells acquire dormancy and drug resistance via interaction with bone marrow stroma cells (BMSC) in a hypoxic microenvironment. Elucidating the mechanisms underlying the regrowth of dormant clones may contribute to further improvement of the prognosis of MM patients. In this study, we find that the CD180/MD-1 complex, a noncanonical lipopolysaccharide (LPS) receptor, is expressed on MM cells but not on normal counterparts, and its abundance is markedly upregulated under adherent and hypoxic conditions. Bacterial LPS and anti-CD180 antibody, but not other Toll-like receptor ligands, enhanced the growth of MM cells via activation of MAP kinases ERK and JNK in positive correlation with expression levels of CD180. Administration of LPS significantly increased the number of CD180/CD138 double-positive cells in a murine xenograft model when MM cells were inoculated with direct attachment to BMSC. Knockdown of CD180 canceled the LPS response in vitro and in vivo. Promoter analyses identified IKZF1 (Ikaros) as a pivotal transcriptional activator of the CD180 gene. Both cell adhesion and hypoxia activated transcription of the CD180 gene by increasing Ikaros expression and its binding to the promoter region. Pharmacological targeting of Ikaros by the immunomodulatory drug lenalidomide ameliorated the response of MM cells to LPS in a CD180-dependent manner in vitro and in vivo. Thus, the CD180/MD-1 pathway may represent a novel mechanism of growth regulation of MM cells in a BM milieu and may be a therapeutic target of preventing the regrowth of dormant MM cells.Significance: This study describes a novel mechanism by which myeloma cells are regulated in the bone marrow, where drug resistance and dormancy can evolve after treatment, with potential therapeutic implications for treating this often untreatable blood cancer.

Integrative Genomic Analysis Predicts Causative Cis-Regulatory Mechanisms of the Breast Cancer-Associated Genetic Variant rs4415084

Previous genome-wide association studies (GWAS) have identified several common genetic variants that may significantly modulate cancer susceptibility. However, the precise molecular mechanisms behind these associations remain largely unknown; it is often not clear whether discovered variants are themselves functional or merely genetically linked to other functional variants. Here, we provide an integrated method for identifying functional regulatory variants associated with cancer and their target genes by combining analyses of expression quantitative trait loci, a modified version of allele-specific expression that systematically utilizes haplotype information, transcription factor (TF)–binding preference, and epigenetic information. Application of our method to a breast cancer susceptibility region in 5p12 demonstrates that the risk allele rs4415084-T correlates with higher expression levels of the protein-coding gene mitochondrial ribosomal protein S30 (MRPS30) and lncRNA RP11-53O19.1. We propose an intergenic SNP rs4321755, in linkage disequilibrium (LD) with the GWAS SNP rs4415084 (r2 = 0.988), to be the predicted functional SNP. The risk allele rs4321755-T, in phase with the GWAS rs4415084-T, created a GATA3-binding motif within an enhancer, resulting in differential GATA3 binding and chromatin accessibility, thereby promoting transcription of MRPS30 and RP11-53O19.1. MRPS30 encodes a member of the mitochondrial ribosomal proteins, implicating the role of risk SNP in modulating mitochondrial activities in breast cancer. Our computational framework provides an effective means to integrate GWAS results with high-throughput genomic and epigenomic data and can be extended to facilitate rapid functional characterization of other genetic variants modulating cancer susceptibility.Significance: Unification of GWAS results with information from high-throughput genomic and epigenomic profiles provides a direct link between common genetic variants and measurable molecular perturbations.

In Silico Evaluation of Pharmacokinetic Optimization for Antimitogram-Based Clinical Trials

Antimitograms are prototype in vitro tests for evaluating chemotherapeutic efficacy using patient-derived primary cancer cells. These tests might help optimize treatment from a pharmacodynamic standpoint by guiding treatment selection. However, they are technically challenging and require refinements and trials to demonstrate benefit to be widely used. In this study, we performed simulations aimed at exploring how to validate antimitograms and how to complement them by pharmacokinetic optimization. A generic model of advanced cancer, including pharmacokinetic–pharmacodynamic monitoring, was used to link dosing schedules with progression-free survival (PFS), as built from previously validated modules. This model was used to explore different possible situations in terms of pharmacokinetic variability, pharmacodynamic variability, and antimitogram performance. The model recapitulated tumor dynamics and standalone therapeutic drug monitoring efficacy consistent with published clinical results. Simulations showed that combining pharmacokinetic and pharmacodynamic optimization should increase PFS in a synergistic fashion. Simulated data were then used to compute required clinical trial sizes, which were 30% to 90% smaller when pharmacokinetic optimization was added to pharmacodynamic optimization. This improvement was observed even when pharmacokinetic optimization alone exhibited only modest benefit. Overall, our work illustrates the synergy derived from combining antimitograms with therapeutic drug monitoring, permitting a disproportionate reduction of the trial size required to prove a benefit on PFS. Accordingly, we suggest that strategies with benefits too small for standalone clinical trials could be validated in combination in a similar manner.Significance: This work offers a method to reduce the number of patients needed for a clinical trial to prove the hypothesized benefit of a drug to progression-free survival, possibly easing opportunities to evaluate combinations.

Pyruvate Dehydrogenase PDH-E1{beta} Controls Tumor Progression by Altering the Metabolic Status of Cancer Cells

Downregulation of pyruvate dehydrogenase (PDH) is critical for the aberrant preferential activation of glycolysis in cancer cells under normoxic conditions. Phosphorylation-dependent inhibition of PDH is a relevant event in this process, but it is not durable as it relies on PDH kinases that are activated ordinarily under hypoxic conditions. Thus, it remains unclear how PDH is durably downregulated in cancer cells that are not hypoxic. Building on evidence that PDH activity depends on the stability of a multi-protein PDH complex, we found that the PDH-E1β subunit of the PDH complex is downregulated to inhibit PDH activity under conditions of prolonged hypoxia. After restoration of normoxic conditions, reduced expression of PDH-E1β was sustained such that glycolysis remained highly activated. Notably, PDH-E1β silencing in cancer cells produced a metabolic state strongly resembling the Warburg effect, but inhibited tumor growth. Conversely, enforced exogenous expression of PDH-E1β durably increased PDH activity and promoted the malignant growth of breast cancer cells in vivo. Taken together, our results establish the specific mechanism through which PDH acts as an oncogenic factor by tuning glycolytic metabolism in cancer cells.Significance: This seminal study offers a mechanistic explanation for why glycolysis is aberrantly activated in normoxic cancer cells, offering insights into this long-standing hallmark of cancer termed the Warburg effect.

Fc-Mediated Anomalous Biodistribution of Therapeutic Antibodies in Immunodeficient Mouse Models

A critical benchmark in the development of antibody-based therapeutics is demonstration of efficacy in preclinical mouse models of human disease, many of which rely on immunodeficient mice. However, relatively little is known about how the biology of various immunodeficient strains impacts the in vivo fate of these drugs. Here we used immunoPET radiotracers prepared from humanized, chimeric, and murine mAbs against four therapeutic oncologic targets to interrogate their biodistribution in four different strains of immunodeficient mice bearing lung, prostate, and ovarian cancer xenografts. The immunodeficiency status of the mouse host as well as both the biological origin and glycosylation of the antibody contributed significantly to the anomalous biodistribution of therapeutic monoclonal antibodies in an Fc receptor-dependent manner. These findings may have important implications for the preclinical evaluation of Fc-containing therapeutics and highlight a clear need for biodistribution studies in the early stages of antibody drug development.Significance: Fc/FcγR-mediated immunobiology of the experimental host is a key determinant to preclinical in vivo tumor targeting and efficacy of therapeutic antibodies.

Polyol Pathway Links Glucose Metabolism to the Aggressiveness of Cancer Cells

Cancer cells alter their metabolism to support their malignant properties. In this study, we report that the glucose-transforming polyol pathway (PP) gene aldo-keto-reductase-1-member-B1 (AKR1B1) strongly correlates with epithelial-to-mesenchymal transition (EMT). This association was confirmed in samples from lung cancer patients and from an EMT-driven colon cancer mouse model with p53 deletion. In vitro, mesenchymal-like cancer cells showed increased AKR1B1 levels, and AKR1B1 knockdown was sufficient to revert EMT. An equivalent level of EMT suppression was measured by targeting the downstream enzyme sorbitol-dehydrogenase (SORD), further pointing at the involvement of the PP. Comparative RNA sequencing confirmed a profound alteration of EMT in PP-deficient cells, revealing a strong repression of TGFβ signature genes. Excess glucose was found to promote EMT through autocrine TGFβ stimulation, while PP-deficient cells were refractory to glucose-induced EMT. These data show that PP represents a molecular link between glucose metabolism, cancer differentiation, and aggressiveness, and may serve as a novel therapeutic target.Significance: A glucose-transforming pathway in TGFβ-driven epithelial-to-mesenchymal transition provides novel mechanistic insights into the metabolic control of cancer differentiation.
