A 61-year-old man with previous history of lung adenocarcinoma underwent 2 F-FDG PET/CT investigations. The first for assessment of enlarged mediastinal lymph nodes revealed an area of increased FDG uptake in the sigmoid colon (located at the right pelvis). Colonoscopy showed a segmental area of ischemic sigmoid colitis, confirmed on histology postbiopsy. The asymptomatic man had no risk factors, and no specific treatment was administered, apart from supportive measures. One year later, there was no significantly abnormal uptake on PET/CT...

BACKGROUND: Recent randomized trials demonstrated that laparoscopic lavage compared with resection for Hinchey III perforated diverticulitis was associated with similar mortality, less stoma formation but a higher rate of early reintervention. The aim of this study was to compare 1-year outcomes in patients who participated in the randomized Scandinavian Diverticulitis (SCANDIV) trial. METHODS: Between February 2010 and June 2014, patients from 21 hospitals in Norway and Sweden presenting with suspected perforated diverticulitis were enrolled in a multicentre RCT comparing laparoscopic lavage and sigmoid resection...

Little information is available on the length of the normal large intestine and its component parts in children. This information would be useful for procedures such as colonoscopy. The aim of this study was to investigate the length of the large intestine and its component parts in New Zealand children. Archival de-identified pediatric supine abdominopelvic computed tomography (CT) scans were retrospectively analyzed. After exclusion criteria, a total of 112 scans (57 males and 55 females) were included in the study and divided into three age groups: 0-2 years (n=33), 4-6 years (n=40), and 9-11 years of age (n=39)...

A middle-aged man was admitted with worsening hip pain, fevers and reduced mobility. These symptoms were preceded by a mechanical fall but despite regular analgesia, symptoms did not resolve. His prior medical history included ischaemic heart disease, hypertension and hypercholesterolaemia. A trauma and orthopaedic review revealed a painful left hip with reduced range of motion. In addition, some mild tenderness in the left iliac fossa was noted. Blood tests revealed markedly raised inflammatory markers. Plain radiographs and ultrasound were normal...

The lack of new antibiotics prompted the investigation of the combination of two existing agents cefepime, a broad-spectrum cephalosporin and tazobactam to broaden its efficacy against extended-spectrum beta-lactamase producing Enterobacteriaceae. We determined the pharmacokinetic and pharmacodynamic properties of the combination in a murine neutropenic thigh model in order to establishing its exposure- response relationships (ERR). The PK of cefepime was determined for five doses; that of tazobactam was determined in earlier studies (Melchers et al Antimicrob...

Dinah Schick, Wolfgang Schwack
Receptor assays like the yeast estrogen screen (YES) performed in microtiter plates normally provide dose-response curves with a sigmoidal shape in semi-log plots. Such sigmoidal plots can be linearized by the logit function resulting in logit-log plots, as mainly known for the evaluation of enzyme-linked immunosorbent assays and radioimmunoassays. Since the planar yeast estrogen screen (pYES) represents the transfer of the receptor assay YES to high-performance thin-layer chromatography (HPTLC), it was assumed to obtain sigmoidal shaped dose-response curves from the measured signals, which subsequently could be used to generate logit-log plots...

Data regarding the effects of selective serotonin reuptake inhibitors (SSRIs), which are a common type of antidepressants, on cardiovascular autonomic function are inconsistent. The present study was conducted to determine the effects of chronic fluoxetine, an SSRI, on blood pressure, cardiac autonomic nervous activities and baroreflex control of heart rate. Male Sprague-Dawley rats were treated with fluoxetine (10mg/kg·day, p.o.) or saline for 14 weeks. Baroreflex function was determined by the sigmoid logistic method based on the heart rate responses to changes in blood pressure elicited by phenylephrine or sodium nitroprusside infusions...

BACKGROUND: ONO-5334 is a cathepsin K inhibitor that induced bone mineral density (BMD) gain in a phase II study in postmenopausal osteoporosis patients. Even though the antiresorptive effect could only be monitored in the morning during the study, simulation can allow the antiresorptive effect to be assessed over 24 h, with assessment of the relationship to BMD gain. METHODS: Inhibition of the serum C-telopeptide of type I collagen (sCTX) level at doses of ONO-5334 of 100 mg once daily (QD), 300 mg QD, and 50 mg twice daily (BID) was simulated using plasma ONO-5334 pharmacokinetic (PK) data for repeated dose administration in a phase I study and corresponding sCTX inhibition from the PK-pharmacodynamic (PK/PD) relationship...

A novel classification model, named the quantum-behaved particle swarm optimization (QPSO)-based weighted multiple kernel extreme learning machine (QWMK-ELM), is proposed in this paper. Experimental validation is carried out with two different electronic nose (e-nose) datasets. Being different from the existing multiple kernel extreme learning machine (MK-ELM) algorithms, the combination coefficients of base kernels are regarded as external parameters of single-hidden layer feedforward neural networks (SLFNs)...

Colorectal cancer is a common disease, representing the third and second most common cause of cancer death in the United States in women and men, respectively. [Ahnen et al.: Mayo Clin Proc 2014;89: 216-224; Siegel et al.: CA Cancer J Clin 2016;66: 7]. It is estimated that 20% of patients have distant metastatic disease at time of diagnosis [Ahnen et al.: Mayo Clin Proc 2014;89: 216-224; Siegel et al.: CA Cancer J Clin 2016;66: 7]. The most common metastatic sites include regional lymph nodes, liver, lungs, and peritoneum via lymphatic/hematogenous dissemination as well as contiguous and transperitoneal routes [Ahnen et al...

An acute sigmoid volvulus is due to the torsion of the sigmoid colon around its mesenteric axis. It mainly occurs in elderly patients and represents an abdominal emergency requiring urgent treatment. A 53-year-old male patient with severe craniocerebral injury and traumatic subarachnoidal bleeding 3 weeks prior presented on the ward with distended abdomen without abdominal pain, muscular defense, or resistances. He featured large volume diarrhea within the last few hours without signs of bleeding. A plain abdominal X-ray demonstrated a coffee bean sign indicating a sigmoid volvulus...

Ankylosing spondylitis (AS) is a common immune-mediated arthropathy primarily affecting the spine and pelvis. Most AS patients have subclinical intestinal inflammation, suggesting the gut microbiome and the immune response play a role in pathogenesis. Susceptibility to AS is primarily genetic, and at least 114 susceptibility variants have been identified to date. We applied bioinformatic methods utilizing epigenetic and gene and protein expression data to identify the cell types through which AS-associated variants operate...

The Hartmann procedure - primarily - was introduced for the treatment of cancerous diseases of sigmoid colon and rectum. In the last few years it was performed in cases with complicated inflammation of the left colon, colon cancers with bowel obstruction or perforation, or in the case of insufficiency of the anastomoses, or in urgent operations after traumatics bowel injuries, when making the anastomosis is at very high risk. Later on the restoration of the continuity of the GI tract can be done traditionally (by laparotomy) or laparoscopically...

We report three affected members, a mother and her two children, of a non-consanguineous Irish family who presented with a suspected autosomal dominant spinocerebellar ataxia characterized by early motor delay, poor coordination, gait ataxia, and dysarthria. Whole exome sequencing identified a novel missense variant (c.106C>T; p.[Arg36Cys]) in the suppressor domain of type 1 inositol 1,4,5-trisphosphate receptor gene (ITPR1) as the cause of the disorder, resulting in a molecular diagnosis of spinocerebellar ataxia type 29...

Individuals with diverticula or outpouchings of the colonic mucosa and submucosa through the colonic wall have diverticulosis, which is usually asymptomatic. In 10-25% of individuals, the diverticula become inflamed, resulting in diverticulitis. Very little is known about the pathophysiology or gene regulatory pathways involved in the development of diverticulitis. To identify these pathways, we deep sequenced RNAs isolated from full-thickness sections of sigmoid colon from diverticulitis patients and control individuals...

BACKGROUND: Marbofloxacin is a veterinary fluoroquinolone with high activity against Pasteurella multocida. We evaluated it's in vivo activity against P. multocida based on in vivo time-kill data in swine using a tissue-cage model. A series of dosages ranging from 0.15 to 2.5 mg/kg were administered intramuscularly after challenge with P. multocida type B, serotype 2. RESULTS: The ratio of the 24 h area under the concentration-time curve divided by the minimum inhibitory concentration (AUC24TCF/MIC) was the best PK/PD index correlated with the in vivo antibacterial effectiveness of marbofloxacin (R2 = 0...
