There continue to be incremental advances in thoracolumbar spine surgery techniques in attempts to achieve more predictable outcomes, minimize risk of complications, speed recovery, and minimize the costs of these interventions. This paper reviews recent literature with regard to emerging techniques of interest in the surgical treatment of lumbar spinal stenosis, fusion fixation and graft material, degenerative lumbar spondylolisthesis, and thoracolumbar deformity and sacroiliac joint degeneration. There continue to be advances in minimal access options in these areas, although robust outcome data are heterogeneous in its support...

The effect of 3-mercaptopropionic acid (MPA)-capped CdTe quantum dots (QDs) on lysozyme was systematically investigated by spectroscopic methods, enzyme activity assay, and calorimetry techniques. Results show that the MPA-capped CdTe QDs binded to lysozyme through van der Walls forces and hydrogen bondings, causing the decrement of α-helical content (∼7%) and increment of β-sheet content (∼11%) of lysozyme. The binding caused static quenching of the fluorescence, while the microenvironment of aromatic amino acid residues did not show any significant alteration...

BACKGROUND: Strong association was documented between human leukocyte antigen (HLA)-B*15:02 and carbamazepine-induced severe cutaneous adverse reactions (SCARs) in Asians. Beyond Asia, the HLA testing is potentially valuable in many countries with increasingly diverse communities of Asian ancestry, to facilitate an early recognition of patient susceptibility to SCARs. OBJECTIVE: To determine the cost-effectiveness of universal HLA-B*15:02 screening in preventing carbamazepine-induced Stevens-Johnson syndrome/ toxic epidermal necrolysis in an ethnically-diverse Malaysian population...

It is suggested that exercisers engage in a process of teleoanticipation and create an exercise template based upon previous experience with the exercise task which guides their perceptions of the amount of effort required for task completion. The present study examined how altering workload intensity during a positive-pressure treadmill task may impact ratings of perceived exertion (RPE). In a counter-balanced design, 15 collegiate cross country runners (7 males, 8 females) performed two 25-min runs at a constant velocity while bodyweight (BW) was either increased from 60% to 100% (INC) or decreased from 100% to 60% (DEC) in 5 min increments...

Exertional dyspnea is present across the spectrum of chronic obstructive pulmonary disease (COPD) severity. However, without realizing it themselves, patients may decrease daily physical activity to avoid distressing respiratory sensations. Dyspnea also may be associated with deconditioning. Cardiopulmonary exercise testing can uncover exertional dyspnea and its physiological determinants in patients with preserved or only mildly-reduced FEV1. Dyspnea in mild COPD can largely be explained by increased "wasted" ventilation in the physiological dead space which heightens the drive to breathe and worsens the inspiratory mechanical constraints...

In the oil-rich Niger Delta, hydrocarbon pollution and oil spillages, gas flaring and sundry anthropogenic activities constitute sources of polycyclic aromatic hydrocarbons (PAHs), with food contamination playing a major role in human exposure. In this study we assessed PAH levels in wild and cultivated edible mushroom species consumed by the general population from the oil producing Niger Delta, Nigeria. The concentrations of USEPA-16 PAHs were determined by gas chromatography and carcinogenic and non-carcinogenic health risks were calculated...

BACKGROUND: With the approval of several new treatments for metastatic castration-resistant prostate cancer (mCRPC), budgetary impact is a concern for health plan decision makers. Budget impact models (BIMs) are becoming a requirement in many countries as part of formulary approval or reimbursement decisions. Cabazitaxel is a second-generation taxane developed to overcome resistance to docetaxel and is approved for the treatment of patients with mCRPC previously treated with a docetaxel-containing regimen...

BACKGROUND: Opioid pain relievers can be highly effective in providing relief for patients suffering from pain. At the same time, prescription opioid abuse, dependence, overdose, and poisoning (hereinafter "abuse") have become a national public health concern. Opioid abuse is also costly: previous estimates of the annual excess costs of opioid abuse to payers range from approximately $10,000 to $20,000 per patient. OBJECTIVES: To (a) provide a comprehensive, current estimate of the economic burden of opioid abuse to commercial payers and (b) explore the drivers of these excess costs of abuse...

Cumulative evidence indicates it may be worthwhile revisiting the twice-weekly hemodialysis (HD) regimen as a valid option for individualized or incremental treatments for selected patients with end-stage renal disease. In this article, we will review the current evidences on the potential pros and cons of twice-weekly HD compared to thrice-weekly HD including China's experience in the practice of twice-weekly HD. A prudent patient selection and close dialysis adequacy monitoring might be necessary for this medical treatment choice...

BACKGROUND: The promising postsurgical weight loss and remission of type 2 diabetes (T2D) from bariatric surgery can be attributed to modified eating physiology after surgical procedures. We sought to investigate the changes in the parameters of consumption behaviors and appetite sensations induced by a mixed meal tolerance test, and to correlate these alterations with age, body mass index, C-peptide levels, and duration of T2D 1 year after bariatric surgery. METHODS: A total of 16 obese patients with T2D who underwent mini-gastric bypass (GB) and 16 patients who underwent sleeve gastrectomy (SG) were enrolled in this study and evaluated using a mixed meal tolerance test one year after surgery...

In independent studies, abnormal global longitudinal strain (GLS) and myocardial inflammation or scar detected by 18F-fludeoxyglucose positron emission tomography (FDG-PET) are associated with poor prognosis among patients with high likelihood for cardiac sarcoidosis. However, commonly used imaging modalities have not been evaluated in the same population. Our goals were to examine the relation between GLS and FDG-PET, and to evaluate the incremental prognostic value of these imaging techniques for predicting major adverse cardiac events (MACE) in patients suspected to have cardiac sarcoidosis...

Heat acclimation over consecutive days has been shown to improve aerobic-based performance. Recently, it has been suggested that heat training can improve performance in a temperate environment. However, due to the multifactorial training demands of athletes, consecutive-day heat training may not be suitable. The current study aimed to investigate the effect of brief (8×30min) intermittent (every 3-4 days) supplemental heat training on the second lactate threshold point (LT2) in temperate and hot conditions...

Statoliths are the only hard structures in the gelatinous bell of most scyphozoan medusae and investigations on these structures could promote investigations of the understudied population dynamics and phylogeny of jellyfish. We examined the statoliths of Aurelia aurita jellyfish of different ages by light microscopic and microtomographic measurements supplemented by scanning electron microscopy. The morphometric analyses confirmed that statolith numbers and sizes increase during jellyfish development and revealed that newly-formed statoliths had similar shapes that may change during statolith growth...
