Two African rodents, Taterillus gracilis and Steatomys caurinus, native to regions of alternate dry and wet seasons, were studied under laboratory conditions. These species differ in estivation behavior, one undergoing pseudoestivation and the other strong estivation. One group of animals of each species was provided with unlimited access to seed and vegetables rich in water, mimicking the food availability of the wet season (control group). A second group of animals of each species was subjected to water restriction for 8 days, mimicking the natural drought that occurs during the dry-hot season. The effects of water restriction on osmoregulation and body water content were assessed from hematocrit, and plasma and urinary osmolalities (PO, UO). Whether the natriuretic peptide system was modified by the osmoregulator adaptation to aridity of these semidesert rodents was examined from measurements of atrial natriuretic peptide (ANP) levels in plasma, atria, and ventricles, in parallel with morphological studies. In both species, UO was increased by water restriction. In water-deprived T. gracilis, ANP levels were about twice (right atria: 1.08 +/- 0.16 microg/mg protein vs control: 0.40 +/- 0.06 microg/mg protein) and plasma concentrations half (0.28 +/- 0.06 ng/ml vs control: 0.64 +/- 0.07 ng/ml) those in control animals. In S. caurinus these variables were not affected by water availability (right atria water restricted: 2. 20 +/- 0.15 microg/mg protein vs control: 2.86 +/- 0.37 microg/mg protein; plasma ANP water restricted: 0.80 +/- 0.12 ng/ml vs control: 0.90 +/- 0.16 ng/ml). Consistent with these quantitative results, immunohistochemical and ultrastructural observations showed an increase in immunostaining for both the N- and the C-terminal ANP and a larger number of granules in the atria of T. gracilis following water restriction, whereas there was no visible change in S. caurinus. Thus, water restriction induced a decrease in ANP secretion in T. gracilis, increasing cardiac storage alongside a reduced urine production. In contrast, in S. caurinus, the natriuretic system was not affected by an 8-day period of water restriction. 相似文献

Frail, older patients pose a challenge to the primary care physician who may often feel overwhelmed by their complex presentation
and tenuous health status. At the same time, family physicians are ideally suited to incorporate the concept of frailty into
their practice. They have the propensity and skill set that lends itself to patient-centred care, taking into account the
individual subtleties of the patient's health within their social context. Tools to identify frailty in the primary care setting
are still in the preliminary stages of development. Even so, some practical measures can be taken to recognize frailty in
clinical practice and begin to address how its recognition may impact clinical care. This review seeks to address how frailty
is recognised and managed, especially in the realm of primary care. 相似文献

Background and purpose
Evaluate the prognostic and predictive impact of HPV-associated p16-expression and assess the combined prognostic impact of p16 and smoking on altered fractionated radiotherapy (AFRT) for oropharyngeal cancer (OPC) within the frames of the update of the Meta-Analysis of Radiotherapy in Carcinomas of Head and neck (MARCH).Materials and methods
Patients with OPC, known tumor p16-status and smoking history were identified from the MARCH update, resulting in a dataset of 815 patients from four randomized trials (RTOG9003, DAHANCA6&7, RTOG0129, ARTSCAN). Analysis was performed using a Cox model stratified by trial and adjusted on gender, age, T-stage, N-stage, type of radiotherapy fractionation, p16, smoking. Primary endpoint was progression-free survival (PFS).Results
In total, 465 patients (57%) had p16-positive tumors and 350 (43%) p16-negative. Compared to p16-negative, p16-positive patients had significantly better PFS (HR?=?0.42 [95% CI: 0.34–0.51], 28.9% absolute increase at 10?years) and OS (HR?=?0.40 [0.32–0.49], 32.1% absolute increase at 10?years). No interaction between p16-status and fractionation schedule was detected. Smoking negatively impacted outcome; in the p16-positive subgroup, never smokers had significantly better PFS than former/current smokers (HR?=?0.49 [0.33–0.75], 24.2% survival benefit at 10?years).Conclusions
No predictive impact of p16-status on response to AFRT could be detected but the strong prognostic impact of p16-status was confirmed and especially p16-positive never smoking patients have superior outcome after RT. 相似文献7.

Introduction
CALGB 9633 was a randomized trial of observation versus adjuvant chemotherapy for patients with stage IB non-small cell lung cancer (NSCLC). In CALGB 9633, the presence of mucin in the primary tumor was associated with shorter disease-free survival (DFS; hazard ratio (HR) = 1.9, p = 0.002) and overall survival (OS; HR = 1.9, p = 0.004).Methods
To validate these results, mucin staining was performed on primary tumor specimens from 780 patients treated on IALT, 351 on JBR.10 and 150 on ANITA. The histochemical technique using mucicarmine was performed. The prognostic value of mucin for DFS and OS was tested in a Cox model stratified by trial and adjusted for clinical and pathological factors. A pooled analysis of all 4 trials was performed for the predictive value of mucin for benefit from adjuvant chemotherapy.Results
The cross-validation group had 48% squamous, 37% adenocarcinoma and 15% other NSCLC compared with 29%, 56%, and 15%, respectively in CALGB. Among 1262 patients with assessable results, mucin was positive in IALT 24%, JBR.10 30%, ANITA 22% compared with 45% in CALGB. Histology was the only significant covariate (p < 0.0001) in multivariate analysis with mucin seen more commonly in adenocarcinoma (56%) compared with squamous (5%) and other NSCLC (15%). Mucin was a borderline negative prognostic factor for DFS (HR = 1.2 [1.0–1.5], p = 0.06) but not significantly so for OS (HR = 1.1 [0.9–1.4], p = 0.25). Prognostic value did not vary according to histology: HR = 1.3 [1.0–1.6] in adenocarcinoma vs. 1.6 [1.2–2.2] for DFS in other histology (interaction p = 0.69). Mucin status was not predictive for benefit from adjuvant chemotherapy (test of interaction: DFS p = 0.27; OS p = 0.49).Conclusions
Mucin was less frequent in the cross-validation group due to its higher percentage of squamous cell carcinomas. The negative impact of mucin was confirmed for DFS but not for OS. Mucin expression was not predictive of overall survival benefit from adjuvant chemotherapy. 相似文献8.

BackgroundComplete resection of non–small-cell lung cancer (NSCLC) offers the potential for cure after surgery and adjuvant chemotherapy. Patients may not benefit and may experience severe toxicity. There are no validated molecular tools to allow better patient selection.Materials and MethodsThe LACE-Bio (LACE [Lung Adjuvant Cisplatin Evaluation]) project includes 4 trials (International Adjuvant Lung Cancer Trial [IALT], Adjuvant Navelbine International Trialist Association [ANITA], JBR10, and Cancer and Leukemia Group B (CALGB)-9633). Immunohistochemistry biomarkers shown in one trial to have a prognostic/predictive effect on overall survival were tested.ResultsThe majority of the promising biomarkers could not be validated; the prognostic effect of tumor infiltrating lymphocytes and β-tubulin was confirmed. Potential causes include tissue fixation, storage, the use of tissue microarrays, and varying reagent/antibody batches.ConclusionsImmunohistochemistry assays from single trials may be misleading and require validation before being used for patient selection. LACE-Bio-2 is evaluating potential genomic biomarkers that may allow more precise selection of patients with NSCLC for adjuvant chemotherapy in NSCLC. 相似文献
