We explored differences between the adipose tissue fatty acid profiles of Great Blue Herons ( Ardea herodias) with and without steatitis. Adipose tissue from birds with steatitis exhibited inflammatory cell infiltration, low abundance of oleic acid, and a lower oleic/stearic desaturation index compared with tissue from birds without steatitis.

Transition of care from the intensive care unit (ICU) to the ward is usually an indication of the patient's improving clinical status, but is also a time when patients are particularly vulnerable. The transition between care teams poses a higher risk of medical error, which can be mitigated by safe and complete patient handoff and medication reconciliation. ICU readmissions are associated with increased mortality as well as ICU and hospital length of stay (LOS); however tools to accurately predict ICU readmission risk are limited...

Purpose: By unlocking antitumor immunity, antibodies targeting programmed cell death 1 (PD-1) exhibit impressive clinical results in non-small cell lung cancer, underlining the strong interactions between tumor and immune cells. However, factors that can robustly predict long-lasting responses are still needed. Experimental Design: We performed in-depth immune profiling of lung adenocarcinoma using an integrative analysis based on immunohistochemistry, flow-cytometry, and transcriptomic data. Tumor mutational status was investigated using next-generation sequencing...

Background Lipedema is a chronic disorder presenting in women during puberty or other times of hormonal change such as childbirth or menopause, characterized by symmetric enlargement of nodular, painful subcutaneous adipose tissue (fat) in the limbs, sparing the hands, feet and trunk. Healthcare providers underdiagnose or misdiagnose lipedema as obesity or lymphedema. Materials and methods The benefits (friend) and negative aspects (foe) of lipedema were collected from published literature, discussions with women with lipedema, and institutional review board approved evaluation of medical charts of 46 women with lipedema...

Swine dysentery (SD) is an economically important diarrheal disease in pigs caused by different strongly hemolytic Brachyspira (B.) species, such as B. hyodysenteriae, B. suanatina and B. hampsonii. Possible associations of epidemiologic data, such as multilocus sequence types (STs) to virulence gene profiles and antimicrobial susceptibility are rather scarce, particularly for B. hyodysenteriae isolates from Germany. In this study, B. hyodysenteriae (n = 116) isolated from diarrheic pigs between 1990 and 2016 in Germany were investigated for their STs, susceptibility to the major drugs used for treatment of SD (tiamulin and valnemulin) and genes that were previously linked with virulence and encode for hemolysins (tlyA, tlyB, tlyC, hlyA, BHWA1_RS02885, BHWA1_RS09085, BHWA1_RS04705, and BHWA1_RS02195), outer membrane proteins (OMPs) (bhlp16, bhlp17...

The nature and existence of mitochondrial lactate oxidation is debated in the literature. Obscuring the issue are disparate findings in isolated mitochondria, as well as relatively low rates of lactate oxidation observed in permeabilized muscle fibres. However, respiration with lactate has yet to be directly assessed in brain tissue with the mitochondrial reticulum intact. To determine if lactate is oxidized in the matrix of brain mitochondria, oxygen consumption was measured in saponin-permeabilized mouse brain cortex samples, and rat prefrontal cortex and hippocampus (dorsal) subregions...

BACKGROUND: EGFR antibodies have shown promise in patients with advanced non-small-cell lung cancer (NSCLC), particularly with squamous cell histology. We hypothesised that EGFR copy number by fluorescence in-situ hybridisation (FISH) can identify patients most likely to benefit from these drugs combined with chemotherapy and we aimed to explore the activity of cetuximab with chemotherapy in patients with advanced NSCLC who are EGFR FISH-positive. METHODS: We did this open-label, phase 3 study (SWOG S0819) at 277 sites in the USA and Mexico...

Lipedema, or adiposis dolorosa, is a common adipose tissue disorder that is believed to affect nearly 11% of adult women worldwide. It is characterized most commonly by disproportionate adipocyte hypertrophy of the lower extremities, significant tenderness to palpation, and a failure to respond to extreme weight loss modalities. Women with lipedema report a rapid growth of the lipedema subcutaneous adipose tissue in the setting of stress, surgery, and/or hormonal changes. Women with later stages of lipedema have a classic "column leg" appearance, with masses of nodular fat, easy bruising, and pain...

Mutations in the epidermal growth factor receptor gene (EGFR) represent one of the most frequent "actionable" alterations in non-small cell lung cancer (NSCLC). Typified by high response rates to targeted therapies, EGFR tyrosine kinase inhibitors (TKIs) are now established first-line treatment options and have transformed the treatment paradigm for NSCLC. With the recent breakthrough designation and approval of the third-generation EGFR TKI osimertinib, available systemic and local treatment options have expanded, requiring new clinical algorithms that take into account individual patient molecular and clinical profiles...

BACKGROUND & AIMS: Many companies provide genetic tests for obesity-related polymorphisms (nutrigenetics) and make dietary recommendations for weight loss that are based on the results. We performed a randomized controlled trial to determine whether more participants who followed a nutrigenetic-guided diet lost ≥5% of their body weight than participants on a standard balanced diet for 8 and 24 weeks. METHODS: We performed a prospective study of 51 obese or overweight U...

Heat waves are not uncommon in Australia, but the event of 2009 was particularly severe and ranks third of the 21 recorded heat wave events in south-eastern Australia in terms of the resulting mortality and morbidity. This is a review of Coronial autopsy findings in South Australia (which has an area of nearly 1 million square kilometres with a population of 1.6 million that predominantly resides within the region of the capital: Adelaide) during the period of the 2009 heat wave. Fifty-four post-mortem examinations were performed on cases in which exposure to high ambient temperature was regarded as having caused or significantly contributed to the death...

INTRODUCTION: Testosterone (T) administration to men increases T, estradiol (E2), dihydrotestosterone (DHT), and fat-free mass (FFM), and decreases fat mass (FM) but does not consistently improve insulin sensitivity (IS). AIM: The aim of this study was to examine the effects of T administration in obese, nondiabetic men on body composition and IS, and to determine if inhibition (i) of metabolism of T to E2 with anastrazole or to DHT with dutasteride alters these effects...

INTRODUCTION: Cetuximab and bevacizumab have each been demonstrated to prolong survival when added to chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). However, the potential benefit of combining cetuximab and bevacizumab together with a platinum-based doublet had not been explored. We designed this phase II trial to evaluate the safety, tolerability, and efficacy of the combination of carboplatin, paclitaxel, cetuximab, and bevacizumab in chemotherapy-naive patients with advanced, nonsquamous NSCLC...

A case of a 58-year-old with fatal anaphylaxis due to multiple bee stings is reported. Supportive evidence for anaphylaxis included post-mortem serum tests, which demonstrated a markedly elevated tryptase level and increased sensitivity to bees on radioallergosorbent test (RAST). At autopsy a previously undiagnosed esophageal adenocarcinoma involving the gastroesophageal (GE) junction was also identified. Histology of the tumor demonstrated significant numbers of mast cells, many of which were degranulating...

Congenital myasthenic syndromes (CMSs) are a heterogeneous group of genetic disorders affecting neuromuscular transmission. The agrin/muscle-specific kinase (MuSK) pathway is critical for proper development and maintenance of the neuromuscular junction (NMJ). We report here an Iranian patient in whom CMS was diagnosed since he presented with congenital and fluctuating bilateral symmetric ptosis, upward gaze palsy and slowly progressive muscle weakness leading to loss of ambulation. Genetic analysis of the patient revealed a homozygous missense mutation c...
