In the management of patients with chronic kidney diseases (CKD), a low-protein diet usually refers to a diet with protein intake of 0.6 to 0.8 grams per kilogram of body weight per day (g/kg/day) and should include at least 50% high-biologic-value protein. It may be supplemented with essential acids or nitrogen- free ketoanalogues if <0.6 g/kg/d. Low-protein diet can reduce proteinuria especially in non-diabetic CKD patients. In hypoalbuminemic patients it may lead to an increase in serum albumin level...

Glioblastoma multiforme (GBM), or grade IV astrocytoma, is the most common type of primary brain tumor. It has a devastating prognosis with a 2-year-overall survival rate of only 26 % after standard treatment, which includes surgery, radiation, and adjuvant chemotherapy with temozolomide. Also lower grade gliomas are difficult to treat, because they diffusely spread into the brain, where extensive removal of tissue is critical. Better understanding of the cancer's biology is a key for the development of more effective therapy approaches...

Using light, we are able to visualize the hemodynamic behavior of the brain to better understand neurovascular coupling and cerebral metabolism. In vivo optical imaging of tissue using endogenous chromophores necessitates spectroscopic detection to ensure molecular specificity as well as sufficiently high imaging speed and signal-to-noise ratio, to allow dynamic physiological changes to be captured, isolated, and used as surrogate of pathophysiological processes. An optical imaging system is introduced using a 16-bands on-chip hyperspectral camera...

Aims and method To describe and explain psychiatrists' responses to metabolic abnormalities identified during screening. We carried out an audit of clinical records to assess rates of monitoring and follow-up practice. Semi-structured interviews with 36 psychiatrists followed by descriptive and thematic analyses were conducted. Results Metabolic abnormalities were identified in 76% of eligible patients screened. Follow-up, recorded for 59%, was variable but more likely with four or more abnormalities. Psychiatrists endorse guidelines but ambivalence about responsibility, professional norms, resource constraints and skills deficits as well as patient factors influences practice...

Cardiovascular disease is the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). The carotid intima-media thickness (CIMT) and arterial stiffness are useful markers of subclinical atherosclerosis and significantly correlate with various metabolic risk factors. Chemerin is one of the adipokines that may represent a link between obesity and inflammation and may be a potential candidate playing a role in the pathogenesis of atherosclerosis and cardiovascular complications. Therefore, we studied the relationship of chemerin levels with atherosclerosis as measured by CIMT in diabetic CKD patients, either predialysis or on hemodialysis (HD)...

The high metabolic rate of harvested asparagus spears (Asparagus officinalis L.) causes rapid deterioration. To extend shelf life, we investigated the effect of sucrose treatment on asparagus during storage. Asparagus spears were treated with 3%, 5%, and 10% sucrose and stored at 2 °C for 20 h. Cellular respiration decreased, but other processes were unaltered by exogenous sucrose. The overall appearance of asparagus treated with 3% sucrose and stored at 2 °C for 18 days was rated as good and excellent, unlike that of untreated spears...

BACKGROUND: Despite intensive efforts directed at initial training in fetal heart rate interpretation, continuing medical education, board certification/recertification, team training and the development of specific protocols for the management of abnormal fetal heart rate patterns, the goals of consistently preventing hypoxia-induced fetal metabolic acidemia and neurologic injury remain elusive. OBJECTIVE: To validate a recently published algorithm for the management of category II fetal heart rate tracings , examine reasons for the birth of infants with significant metabolic acidemia despite the use of electronic fetal heart rate monitoring and critically examine the limits of EFHRM in the prevention of neonatal metabolic acidemia...

Metabolic Syndrome (MetS) is one of the most common factors underlying the high rate of mortality observed in patients with schizophrenia. Recent research on this topic revealed that many of the patients studied were, in fact, in a medicated state. As such, it is unclear whether MetS is causally associated with the disorder itself or the medication used to treat it. In this study, patients with a clinically high risk of expressing first episode psychosis (CHR) were examined regarding the prevalence of MetS...

Since its foundation by remarkably talented and insightful individuals, prominently including Pepper Dehner, pediatric soft tissue tumor pathology has developed at an immense rate. The morphologic classification of tumoral entities has extensively been corroborated, but has also evolved with refinement or realignment of these classifications, through accruing molecular data, with many derivative ancillary diagnostic assays now already well-established. Tumors of unclear histogenesis, classically morphologically undifferentiated, are prominent amongst pediatric sarcomas, however, the classes of undifferentiated round- or spindle-cell-tumors-not-otherwise-specified are being dismantled gradually with the identification of their molecular underpinnings...

In order to control food losses and wastage, monitoring the microbial diversity of food products, during processing and storage is important, as studies have highlighted the metabolic activities of some microorganisms which can lead to spoilage. Knowledge of this diversity can be greatly improved by using a metagenetic approach based on high throughput 16S rRNA gene sequencing, which enables a much higher resolution than culture-based methods. Moreover, the Jameson effect, a phenomenon described by Jameson in 1962, is often used to classify bacterial strains within an ecosystem...

Aim: Patients with cardiac diseases, especially ischemic heart disease, are known to have a high prevalence of diabetes mellitus (DM). They are at risk of having inadequate glucose control. An intensive diabetes screening and treatment program was developed to identify and treat DM in patients admitted with cardiac diseases. Methods: Adult inpatients of 2 cardiac wards, namely Ward-A and Ward-B, at Nanjing Hospital, Nanjing, China, were studied. Patients were randomly assigned into either ward. In addition to routine examination and treatment, an intensive screening and treatment program to identify and treat patients with DM or impaired glucose regulation (IGR) was only applied in Ward-A patients...

Phthalate esters (PEs) are easily metabolized and commonly excreted via urine within 24h, therefore their bioaccumulation potential is thought to be rather low. In the present study, we developed a sample preparation combined with a new microextraction method to measure seven PE metabolites in nails. The use of whole nails did not result in significantly different levels compared to powdered nails, which makes the method very fast and user friendly. The method was validated using whole nails showing good accuracy, satisfactory precision and low limits of quantification (2-14ng/g)...

Acceleration of glycolysis is a characteristic of neoplasia. Previous studies have shown that a metabolic shift occurs in many tumors and correlates with a negative prognosis. The present study aimed to investigate the glycolytic profile of thyroid carcinoma cell lines. We investigated glycolytic and oxidative parameters of two thyroid carcinoma papillary cell lines (BCPAP and TPC1) and the non-tumor cell line NTHY-ori. All carcinoma cell lines showed higher rates of glycolysis efficiency, when compared to NTHY-ori, as assessed by a higher rate of glucose consumption and lactate production...

Renal cell carcinoma (RCC) comprises 2‑3% of all malignant tumors in adults. Many studies have established the key roles of smoking, hypertension and other components of metabolic syndrome in the occurrence of RCC. Diabetes mellitus (DM), one of the main consequences of metabolic syndrome, appears much more often in patients with RCC. The prognosis for patients suffering from both diabetes and RCC is worse than for those with kidney cancer only. Diabetes is linked to higher rate of recurrence and a greater number of distant metastases...

Metabolic syndrome (MetS) is a leading public health and clinical challenge worldwide. MetS represents a group of interelated risk factors that predict cardiovascular diseases (CVD) and diabetes mellitus (DM). Its prevalence ranges between 10 and 84%, depending of the geographic region, urban or rural environment, individual demographic characteristics of the population studied (sex, age, racial and ethnic origin), as well as the criteria used to define MetS. Persons with MetS have higher mortality rate when compared with people without MetS, primarily caused by progressive atherosclerosis, accelerated by pro-inflammatory and pro-coagulation components of MetS...

The purpose of this study was to evaluate the effects of 6 weeks of supramaximal exercise training (SET) on performance variables and metabolic changes in sedentary obese adults. Twenty-four obese adults were randomly allocated into a non-trained (NT) [n = 12; body mass index (BMI) = 33(3)] and SET group [n = 12; BMI = (33(2)]. After baseline metabolic and fitness measurements, the participants completed a 6-week SET intervention. Metabolic, anthropometric, and fitness assessments were repeated post-intervention...

While the words "fit" and "healthy" are often used synonymously in everyday language, the terms have entirely separate meanings. Fitness describes the ability to perform a given exercise task, and health explains a person's state of well-being, where physiological systems work in harmony. Although we typically view athletes as fit and healthy, they often are not. The global term we place on unhealthy athletes is the overtraining syndrome. In this current opinion, we propose that two primary drivers may contribute to the development of the overtraining syndrome, namely high training intensity and the modern-day highly processed, high glycemic diet...

Marijuana is used by millions of people, with use likely to increase in the USA because of the trend towards increased decriminalization and legalization. Obesity and diabetes mellitus (DM) rates have increased dramatically in the USA over the past 30 years, with a recent estimate of 29 million individuals with DM. Because there is a plausible link between marijuana use and diabetes due to the known effects of cannabinoids on adipose tissue and glucose/insulin metabolism, it is important to study and understand how marijuana use is related to obesity and diabetes...

AIMS/HYPOTHESIS: Inverse associations between physical activity (PA) and type 2 diabetes mellitus are well known. However, the shape of the dose-response relationship is still uncertain. This review synthesises results from longitudinal studies in general populations and uses non-linear models of the association between PA and incident type 2 diabetes. METHODS: A systematic literature search identified 28 prospective studies on leisure-time PA (LTPA) or total PA and risk of type 2 diabetes...
