REVIEW
Alper Sen, Kadir Özdamar
OBJECTIVES: To compare the functional and anatomical success rates of the fascial versus perichondrial grafts in pediatric endoscopic type 1 tympanoplasties. METHODS: This retrospective clinical study was conducted on 40 pediatric patients (23 females and 17 males; mean age: 10.0 ± 1.7 years; the age range: 6-13) who were operated with a transcanal endoscopic type 1 tympanoplasty. The study participants were assigned to two groups by graft types. The patients were assigned to either the tragal cartilage perichondrium group (Group A) or the fascia of the temporal muscle (Group B)...

Li Baogui, Chen Juwen
OBJECTIVE: For odontoid fractures, surgical treatment approaches including anterior odontoid screw fixation approach and the posterior C1-C2 arthrodesis approach are generally adopted in practice. However, the choice of different surgical procedures remains controversial. In addition to surgical technique, the fusion rate is an important factor contributing to the clinical efficacy. Therefore, this study was aimed to investigate the discrepancy in fusion rate between these two surgical approaches through synthesizing the currently available evidence on the topic...

OBJECTIVE: Non-significant p values derived from null hypothesis significance testing do not distinguish between true null effects or cases where the data are insensitive in distinguishing the hypotheses. This study aimed to investigate the prevalence of Bayesian analyses in gerontological psychology, a statistical technique that can distinguish between conclusive and inconclusive non-significant results, by using Bayes factors (BFs) to reanalyze non-significant results from published gerontological research...

Massive datasets are often regarded as a panacea to the underpowered studies of the past. At the same time, it is becoming clear that in many of these datasets where thousands of variables are measured across hundreds of thousands or millions of individuals, almost any desired relationship can be inferred with a suitable combination of covariates or analytic choices. Inspired by the Genome-Wide Association Study (GWAS) analysis paradigm that has transformed human genetics, "X-Wide Association Studies" or "XWASs" have emerged as a popular approach to systematically analyze non-genetic datasets and guard against false positives...

18 F-fluorocholine (FCH) PET/CT is a promising and increasingly used scan technique in preoperative imaging of parathyroid adenoma. Several acquisition methods have been evaluated in literature but the optimal image acquisition time point after administration of the tracer is still under debate. Methods: Patients with hyperparathyroidism, who received a dual-time-point FCH PET/CT (image acquisition 5 min and 60 min post injection) with histologically proven pathological parathyroid glands were retrospectively included in the study...

The genetic architecture of complex human traits and diseases is affected by large number of possibly interacting genes, but detecting epistatic interactions can be challenging. In the last decade, several studies have alluded to problems that linkage disequilibrium can create when testing for epistatic interactions between DNA markers. However, these problems have not been formalized nor have their consequences been quantified in a precise manner. Here we use a conceptually simple three locus model involving a causal locus and two markers to show that imperfect LD can generate the illusion of epistasis, even when the underlying genetic architecture is purely additive...

OBJECTIVE: The Psoriatic Arthritis Disease Activity Score (PASDAS) is a composite measure of psoriatic arthritis (PsA) disease activity. The length of its patient-reported components raises concern about questionnaire burden. The PASDAS includes the SF-36 measure. We investigated the agreement between PASDAS and a modified PASDAS (mPASDAS) which substituted the SF-36 with the shortened SF-12. METHODS: 100 patients meeting CASPAR criteria for PsA were consecutively recruited...

US image registration is an important task e.g. in Computer Aided Surgery. Due to tissue deformation occurring between pre-operative and interventional images often deformable registration is necessary. We present a registration method focused on surface structures (i.e. saliencies) of soft tissues like organ capsules or vessels. The main concept follows the idea of representative landmarks (so called leading points). These landmarks represent saliencies in each image in a certain region of interest. The determination of deformation was based on a geometric model assuming that saliencies could locally be described by planes...

OBJECTIVE: Males with peripheral arterial disease (PAD) are at high risk of ischaemic stroke given that atherogenic risk factors for both diseases are similar. We hypothesized that neurologically asymptomatic males diagnosed with PAD would demonstrate calcified carotid artery plaques (CCAP) on panoramic images (PI) significantly more often than similarly aged males not having PAD. METHODS: Investigators implemented a retrospective cross-sectional study. Subjects were male patients over age 50 diagnosed with PAD by ankle-brachial systolic pressure index results of <mml:math xmlns:mml="http://www...

PURPOSE: In DTC patients, 131-radioiodine therapy has routinely been used for many years for thyroid remnant ablation after thyroid surgery. To date, two different strategies can be used to achieve sufficient TSH stimulation on thyroid remnant: (I) Levo-thyroxine withdrawal or (II) rhTSH stimulation. The aim of our study was to compare the abdominal absorbed dose ratio between differentiated thyroid cancer patients who underwent thyroid remnant ablation after either L-T4 withdrawal or rhTSH stimulation...

Emerging evidence suggested a converging mechanism in neurodegenerative brain diseases (NBD) involving early neuronal network dysfunctions and alterations in the homeostasis of neuronal firing as culprits of neurodegeneration. In this study, we used paired-end short-read and direct long-read whole genome sequencing to investigate an unresolved autosomal dominant dementia family significantly linked to 7q36. We identified and validated a chromosomal inversion of ca. 4 Mb, segregating on the disease haplotype and disrupting the coding sequence of dipeptidyl-peptidase 6 gene (DPP6)...

Glaucoma is the leading cause of irreversible blindness worldwide and requires regular monitoring upon diagnosis to ascertain whether the disease is stable or progressing. However, making this determination remains a difficult clinical task. Recently, a novel spatiotemporal boundary detection predictor of glaucomatous visual field (VF) progression (STBound) was developed. In this work, we explore the ability of STBound to differentiate progressing and non-progressing glaucoma patients in comparison to existing methods...

SUMMARY: In many areas of biological research, hypotheses are tested in a sequential manner, without having access to future p-values or even the number of hypotheses to be tested. A key setting where this online hypothesis testing occurs is in the context of publicly available data repositories, where the family of hypotheses to be tested is continually growing as new data is accumulated over time. Recently, Javanmard and Montanari (Ann. Stat. 46:526-554, 2018) proposed the first procedures that control the FDR for online hypothesis testing...

Cervical cancer is the second major female cancer in India and constitutes one fourth of the world's burden. Human Papilloma Virus (HPV) infection is an essential but insufficient cause for cervical cancer. Genetic variants in MicroRNAs (miRNAs/miRs) play an important role in the susceptibility of various types of cancers. To evaluate the association of Single Nucleotide Polymorphisms (SNPs) in miR-146a (rs2910164), miR-196a2 (rs11614913) and miR-499 (rs3746444), with cervical cancer susceptibility in Indian population...
