DEXA measures of body fat percentage and acute phase proteins among breast cancer survivors: a cross-sectional analysis.

Background: C-reactive protein (CRP) and Serum amyloid A protein (SAA) increases with systemic inflammation and are related to worse survival for breast cancer survivors. This study examines the association between percent body fat and SAA and CRP and the potential interaction with NSAID use and weight change.

Methods: Participants included 134 non-Hispanic white and Hispanic breast cancer survivors from the Health, Eating, Activity, and Lifestyle Study.

Hydrodefluorination and hydrogenation of fluorobenzene under mild aqueous conditions.

Fluorinated organic compounds are increasingly used in many applications, and their release to the environment is expected. It is therefore important to find suitable methods for degradation of fluorinated compounds under environmentally relevant conditions. In this study, a simple heterogeneous rhodium-based catalytic system (Rh/Al(2)O(3) and H(2)) for hydrodefluorination and hydrogenation of fluorobenzene under mild aqueous conditions (1 atm of H(2), ambient temperature) was developed and the underlying reaction mechanism was investigated.

ADRB2 G-G haplotype associated with breast cancer risk among Hispanic and non-Hispanic white women: interaction with type 2 diabetes and obesity.

Introduction: Polymorphisms in the beta-2-adrenergic receptor (ADRB2) gene have been studied in relation to risk of type 2 diabetes and obesity, risk factors that have received increased attention in relation to breast cancer. We evaluated the hypothesis that ADRB2 variants (rs1042713, rs1042714) are associated with breast cancer risk in non-Hispanic white (NHW) and Hispanic (H) women using data from a population-based case-control study conducted in the southwestern United States.

Methods: Data on lifestyle and medical history, and blood samples, were collected during in-person interviews for incident primary breast cancer cases (1,244 NHW, 606 H) and controls (1,330 NHW, 728 H).

Associations of insulin-like growth factor and insulin-like growth factor binding protein-3 with mortality in women with breast cancer.

Elevated circulating insulin-like growth factor-1 (IGF-1), a breast epithelial cell mitogen, is associated with breast cancer development. However, its association with breast cancer survival is not established. Circulating concentrations of IGF-1 are controlled via binding proteins, including IGF Binding Protein-3 (IGFBP-3), that may modulate the association of IGF-1 with breast-cancer outcomes.

Lipid profiles and outcome in patients treated by intravenous thrombolysis for cerebral ischemia.

Objective: To determine whether low low-density lipoprotein cholesterol (LDL-C) but not high-density lipoprotein cholesterol (HDL-C) and triglyceride concentrations are associated with worse outcome in a large cohort of ischemic stroke patients treated with IV thrombolysis.

Methods: Observational multicenter post hoc analysis of prospectively collected data in stroke thrombolysis registries. Because of collinearity between total cholesterol (TC) and LDL-C, we used 2 different models with TC (model 1) and with LDL-C (model 2).

Zurich Fabry study - prevalence of Fabry disease in young patients with first cryptogenic ischaemic stroke or TIA.

Background And Purpose: The etiology of stroke in young patients remains undetermined in up to half of the cases. Data on prevalence of Fabry disease (FD) in young people with cryptogenic ischaemic stroke are limited and controversial. We aimed to evaluate the frequency of unrecognized FD in a cohort of stroke patients at a tertiary stroke center.

Is renal thrombotic angiopathy an emerging problem in the treatment of ovarian cancer recurrences?

Background And Objective: Ovarian cancer is usually diagnosed at an advanced stage, with most patients undergoing surgery followed by platinum- and taxane-based chemotherapy. After initial clinical remission, the majority recur, leading to additional treatments, including not only platinums and taxanes but also pegylated liposomal doxorubicin (PLD), gemcitabine, topotecan, and, more recently, bevacizumab, which may extend survival times. PLD, in particular, has been extensively studied by our group, with encouraging therapeutic results.

Decision-making using fMRI in clinical drug development: revisiting NK-1 receptor antagonists for pain.

Substance P (SP) and neurokinin-1 receptors (NK-1R) are localized within central and peripheral sensory pain pathways. The roles of SP and NK-1R in pain processing, the anatomical distribution of NK-1R and efficacy observed in preclinical pain studies involving pain and sensory sensitization models, suggested that NK-1R antagonists (NK-1RAs) would relieve pain in patient populations. Despite positive data available in preclinical tests for a role of NK-1RAs in pain, clinical studies across several pain conditions have been negative.

Cyclic long-term loading of a bilateral fixed-angle plate in comparison with tension band wiring with K-wires or cannulated screws in transverse patella fractures.

Purpose: A bilateral fixed-angle plate was biomechanically compared to the two currently preferred methods of osteosynthesis for transverse patella fractures. It was hypothesized that the new angle-stable implant would provide a secure and sustainable fracture fixation, superior to the established standard techniques.

Methods: Twenty-one identical patellae made of polyurethane foam (Sawbones(®)), osteotomized to create a transverse two-part fracture, were fixed with modified anterior tension wiring, cannulated lag screws with anterior tension wiring or bilateral polyaxial 2.

An aryloxypropanolamine hβ3-adrenoceptor agonist as bladder smooth muscle relaxant.

The relaxant effect of an aryloxypropanolamine β3-adrenoceptor agonist on carbachol pre-contracted human detrusor muscle strips was evaluated and compared with literature results from reference compounds of similar mode of action, including mirabegron. A significant relaxation was observed for rac-4-{2-hydroxy-3-[1-(5-phenylthieno[2,3-d]pyrimidin-4-yl)piperidin-4-ylamino]propoxy}-2-(hydroxymethyl)phenol which was similar to that exerted by mirabegron. In order to allow for a thorough discussion of results in comparison to reference compounds, their affinity, selectivity and efficacy as hβ3-AR agonists have been evaluated and discussed thoroughly.

The ocular pulse amplitude as a noninvasive parameter for carotid artery stenosis screening: a test accuracy study.

Purpose: To investigate a potential correlation between the ocular pulse amplitude (OPA; i.e., the intraocular pressure difference between the systolic and diastolic phases of the heartbeat) and the severity of carotid artery stenosis (CAS) and to test its role as a screening parameter for CAS during routine ophthalmic examination.

Drosophila Pez acts in Hippo signaling to restrict intestinal stem cell proliferation.

The conserved Hippo signaling pathway acts in growth control and is fundamental to animal development and oncogenesis. Hippo signaling has also been implicated in adult midgut homeostasis in Drosophila. Regulated divisions of intestinal stem cells (ISCs), giving rise to an ISC and an enteroblast (EB) that differentiates into an enterocyte (EC) or an enteroendocrine (EE) cell, enable rapid tissue turnover in response to intestinal stress.

Comparative platelet proteome analysis reveals an increase of monoamine oxidase-B protein expression in Alzheimer's disease but not in non-demented Parkinson's disease patients.

Monoamine oxidase-B (Mao-B) catalysing the breakdown of the neurotransmitter dopamine, is known to be involved in the pathophysiology of Parkinson's (PD) and Alzheimer's disease (AD). Increased brain Mao-B activity is associated with AD. This alteration can also be seen in platelets, albeit the cause has hitherto remained elusive.

The Munich-LTX-Score: predictor for survival after lung transplantation.

Background: The purpose of this study was to create a prognostic score calculated one yr after LTX based on post-transplant factors inclusive of donor and recipient characteristics that could be used to predict long-term survival in patients after lung transplantation (LTX).

Methods: Uni- and multivariate analysis in 206 consecutive LTX patients identified independent risk factors for post-transplant mortality and onset of bronchiolitis obliterans syndrome. Munich-LTX-Score is devised by summing up each identified risk factor.

Bioguided isolation of (9Z)-octadec-9-enoic acid from Phellodendron amurense Rupr. and identification of fatty acids as PTP1B inhibitors.

The therapy of type-2 diabetes mellitus is one of the major challenges of our age. A possible strategy to prevent the progression of this disease is the inhibition of protein tyrosine phosphatase 1B (PTP1B), a major negative regulator in the insulin and leptin signalling pathway. Phellodendri amurensis cortex is a well-known Asian herbal drug traditionally used as antiphlogistic, antibacterial, and anti-inflammatory agent, and its efficacy against diabetes-related symptoms is reported as well.

Modulation of CNS pain circuitry by intravenous and sublingual doses of buprenorphine.

Buprenorphine (BUP) is a partial agonist at μ-, δ- and ORL1 (opioid receptor-like)/nociceptin receptors and antagonist at the κ-opioid receptor site. BUP is known to have both analgesic as well as antihyperalgesic effects via its central activity, and is used in the treatment of moderate to severe chronic pain conditions. Recently, it was shown that intravenous (IV) administration of 0.

Effective surgical treatment of cerebral cavernous malformations: a multicenter study of 79 pediatric patients.

Object: Cerebral cavernous malformations (CCMs) are common vascular lesions in the brain, affecting approximately 0.5% of the population and representing 10%-20% of all cerebral vascular lesions. One-quarter of all CCMs affect pediatric patients, and CCMs are reported as one of the main causes of brain hemorrhage in this age group.

[Upper leg amputation. Transfemoral amputation].

Objective. Amputation through the diaphysis of the femur at the most peripheral level possible. The stump, covered with soft tissue flaps, is free from pain.

[Knee disarticulation and through-knee amputation].

Objective: A knee disarticulation or a through-knee stump is superior compared to a transfemoral stump. The thigh muscles are all preserved, and the muscle balance remains undisturbed. The range of motion of the hip joint is not limited.

[Forefoot and midfoot amputations].

Objective: Partial foot amputations are feasible regardless of the causal condition, including peripheral vascular disease with a few exceptions. Compared to higher amputation levels, a good foot stump permits full end bearing and enables the patient, even with a hindfoot stump, to walk without the need for a prosthesis. The more peripheral the amputation level selected, the greater the need for gentle tissue handling and meticulous postoperative care, but also the greater the risk of a breakdown requiring stump revision surgery.

[Transtibial amputation].

Objective: To make a transtibial stump as long as possible, free from local and phantom pain with a maximum of terminal load bearing. In order to preserve the knee joint, an ultra-short tibial stump of 5-6 cm may be indicated.

Indications: A hindfoot amputation level is not possible to achieve.

Imaging drugs with and without clinical analgesic efficacy.

The behavioral response to pain is driven by sensory and affective components, each of which is mediated by the CNS. Subjective pain ratings are used as readouts when appraising potential analgesics; however, pain ratings alone cannot enable a characterization of CNS pain circuitry during pain processing or how this circuitry is modulated pharmacologically. Having a more objective readout of potential analgesic effects may allow improved understanding and detection of pharmacological efficacy for pain.

IV thrombolysis and statins.

Objective: To examine whether prior statin use affects outcome and intracranial hemorrhage (ICH) rates in stroke patients receiving IV thrombolysis (IVT).

Methods: In a pooled observational study of 11 IVT databases, we compared outcomes between statin users and nonusers. Outcome measures were excellent 3-month outcome (modified Rankin scale 0-1) and ICH in 3 categories.

Sarcopenia and obesity.

Four body composition phenotypes exist in older adults: normal, sarcopenic, obese, and a combination of sarcopenic and obese. There is no consensus, however, on the definitions and classifications of these phenotypes and their etiology and consequences continue to be debated. The lack of standard definitions, particularly for sarcopenia and sarcopenic obesity, creates challenges for determining prevalence across different populations.

Outcome of intravenous thrombolysis in stroke patients weighing over 100 kg.

Background: Intravenous thrombolysis with alteplase for ischemic stroke is fixed at a maximal dose of 90 mg for safety reasons. Little is known about the clinical outcomes of stroke patients weighing >100 kg, who may benefit less from thrombolysis due to this dose limitation.

Methods: Prospective data on 1,479 consecutive stroke patients treated with intravenous alteplase in six Swiss stroke units were analyzed.
