PURPOSE: Breast cancer patients who require locoregional lymph node (LLN) irradiation can be treated using a hybrid RapidArc technique combining 2 tangential and 3 RapidArc fields. Because the creation of hybrid RapidArc plans is complex and labor-intensive, we developed an automated treatment planning workflow using the scripting application programming interface of the Eclipse treatment planning system. METHODS AND MATERIALS: Fifteen patients (5 right- and 10 left-sided) previously treated with breast + LLN radiation therapy were replanned using the script...

BACKGROUND: The purpose of the current study was to determine the association between sedentary time and physical activity with clinically relevant health outcomes among adults with impaired spirometry and those with or without self-reported obstructive lung disease (asthma or COPD). METHODS: Data from participants of the Canadian Longitudinal Study on Aging were used for analysis (n = 4156). Lung function was assessed using spirometry. Adults were said to have impaired spirometry if their Forced Expiratory Volume in 1 s was <5th percentile lower limit of normal (LLN)...

BACKGROUND: The prognostication of metastatic renal cell carcinoma (mRCC) is based on Memorial Sloan Kettering Cancer Center (MSKCC) and International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk classifications. Research has shown that hyponatremia is associated with worse prognosis in cancer. We analyzed the association of hyponatremia and outcome in everolimus-treated mRCC patients. PATIENTS AND METHODS: Baseline and on-treatment (≤12 weeks) sodium in 233 mRCC patients was analyzed using Kaplan-Meier, Cox regression and logistic regression...

Here we report a case of advanced rectal and prostate cancer with synchronous lateral lymph node (LLN) metastases that was treated with laparoscopic surgery. A 71-year-old man presented with fecal occult blood and was diagnosed with rectal cancer. A metastatic right LLN was suspected after CT examination of a 19-mm lymph node (proximal internal iliac artery region) and a 13-mm lymph node (distal internal iliac artery region) in the right lateral region. We planned neoadjuvant chemotherapy to suppress local and distant recurrence...

BACKGROUND: COPD is a major cause of morbidity and mortality across the world and new estimates of prevalence and trend are of great importance. We aimed to estimate the prevalence and trend of COPD from 1995-1997 to 2006-2008 in Norwegian adults ≥40 years from the Nord-Trøndelag Health Study. MATERIAL AND METHODS: COPD was assessed using a fixed-ratio and lower limit of normal (LLN) criteria. Pre-bronchodilator spirometry was performed during 1995-1997 (n = 7158) and 2006-2008 (n = 8788)...

RATIONALE: Past research demonstrates a possible association between herbicide exposure and respiratory health. Biologic plausibility and inhalation as a mode of exposure further support the contention that herbicides may act as adverse contributors to respiratory status, especially in military personnel who were responsible for chemical maintenance and distribution during the Vietnam War. OBJECTIVES: This study examines the association between chronic obstructive pulmonary disease and herbicide exposure among Vietnam-era U...

Over the last decades, trivalent lanthanide ions (Ln3+ ) have gained much attention due to their peculiar luminescence, which opened the way to a broad range of applications, from medical diagnostic to lasers. Their impact on nonlinear optical (NLO) properties also attracted interest, especially in the framework of lanthanide complexes. Several experimental studies demonstrated that the quadratic hyperpolarizability varies with the number of 4f-electrons, with a stronger effect on dipolar than octupolar components...

Liquid lipid nanocapsules (LLN) represent a promising new generation of drug-delivery systems. They can carry hydrophobic drugs in their oily core, but the composition and structure of the surrounding protective shell determine their capacity to survive in the circulatory system and to achieve their goal: penetrate tumor cells. Here, we present a study of LLN covered by the protein human serum albumin (HSA) and loaded with curcumin as a hydrophobic model drug. A cross-linking procedure was performed to further strengthen the protective protein layer...

A presumed consequence of using a fixed ratio for the definition of airflow limitation (AFL) has been overdiagnosis among older individuals and underdiagnosis among younger individuals. However, the prognosis of younger individuals with potentially underdiagnosed AFL is poorly described. We hypothesised that potential underdiagnosis of AFL at a younger age is associated with poor prognosis.We assigned 95 288 participants aged 20-100 years from the Copenhagen General Population Study into the following groups: individuals without AFL with forced expiratory volume in 1 s (FEV1 )/forced vital capacity (FVC) ≥0...

BACKGROUND: Cervical lymph node metastasis of papillary thyroid carcinoma (PTC) is common. However, whether undergoing prophylactic central lymph node (CLN) dissection or lateral lymph node (LLN) dissections to prevent metastasis is still controversial. This study aimed to retrospectively investigate the risk factors of LLN metastasis in clinical lymph node-negative (cN0) PTC patients. METHODS: We retrospectively studied 783 lymph node-negative (cN0) PTC patients who underwent total thyroidectomy plus CLN dissection and LLN dissection...

OBJECTIVE: There is controversy about the diagnostic criteria, prevalence, symptoms, and spirometry characteristics of asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO). Recent data indicate that the fixed method for diagnosing airway obstruction (AO) may overestimate ACO prevalence in the elderly, and a variable method may be more accurate. We aimed at estimating ACO prevalence in a general population sample and comparing patient and clinical features in subjects with ACO, COPD, and asthma...

A 74-year-old male had undergone laparoscopic abdominoperineal resection for lower rectal cancer in July 2009. The pathological diagnosis was T2, N0, M0, pStage I (TNM 7th). Because of pathological venous invasion, adjuvant chemotherapy with Tegafur-uracil(UFT)plus Leucovorin for a year was performed. A CT examination revealed slowly growing peripheral right internal iliaclymph node. PET-CT demonstrated a 20mm right lateral lymph node(LLN)metastasis without other distant metastases. On diagnosis of solitary LLN metastasis of rectal cancer, the patient underwent surgical lymph node resection in September 2014...

BACKGROUND: Flavonoids exert anti-inflammatory properties and modulate oxidative stress in vitro, suggesting a protective effect on lung function, but epidemiological studies examining this association are scarce. METHODS: A stratified random sample was drawn from the GA²LEN screening survey, in which 55,000 adults aged 15 to 75 answered a questionnaire on respiratory symptoms. Post-bronchodilator spirometry was obtained from 2850 subjects. Forced vital capacity (FVC), the ratio between the forced exhaled volume in 1 second (FEV₁) and FVC (FEV₁/FVC), FVC below lower limit of normal (FVC < LLN), and FEV₁/FVC < LLN were calculated...

The fixed ratio criterion of forced expiratory volume in 1 s/forced vital capacity <0.70 for diagnosing airway obstruction may overdiagnose the condition, particularly in the elderly, so the lower limit of normal (LLN) is recommended as the most appropriate criterion. Our aim was to compare LLN versus fixed ratio on the prevalence of chronic obstructive pulmonary disease (COPD) and examine the association between respiratory symptoms and airway obstruction defined by LLN and fixed ratio. 12 449 twins aged 40-80 years participated in a nationwide survey using the Danish Twin Registry...
