Characterization of the preweaned Holstein calf fecal microbiota prior to, during, and following resolution of uncomplicated gastrointestinal disease.

Little is known about shifts in the fecal microbiome of dairy calves preceding and following the incidence of gastrointestinal disease. The objective of this cohort study was to describe the fecal microbiome of preweaned dairy calves before, during, and after gastrointestinal disease. A total of 111 Holstein dairy calves were enrolled on 2 dairies (D1 and D2) and followed until 5 weeks old.

Cognitive assessment to optimize prediction of functional outcome in subacute hip fracture: a short-term prospective study.

Background: Cognitive impairment is a long-known negative prognostic factor after hip fracture. Cognition is usually screened by a single easy-to-administer bedside tool, but recent studies have shown that screening tests may be not enough to rule out cognitive impairment with an unfavorable prognostic role. Unfortunately, data on outcome prediction by further cognitive assessments is sparse.

Comparative diagnoses of respiratory disease in preweaned dairy calves using sequential thoracic ultrasonography and clinical respiratory scoring.

Aims: Bovine respiratory disease (BRD) has serious impacts on dairy production and animal welfare. It is most commonly diagnosed based on clinical respiratory signs (CRS), but in recent years, thoracic ultrasonography (TUS) has emerged as a diagnostic tool with improved sensitivity and specificity. This study aimed to assess the alignment of BRD diagnoses based on a Clinical Respiratory Scoring Chart (CRSC) and weekly TUS findings throughout the progression of BRD of variable severity in preweaned Holstein dairy heifers.

Blocking Dectin-1 prevents colorectal tumorigenesis by suppressing prostaglandin E2 production in myeloid-derived suppressor cells and enhancing IL-22 binding protein expression.

Dectin-1 (gene Clec7a), a receptor for β-glucans, plays important roles in the host defense against fungi and immune homeostasis of the intestine. Although this molecule is also suggested to be involved in the regulation of tumorigenesis, the role in intestinal tumor development remains to be elucidated. In this study, we find that azoxymethane-dextran-sodium-sulfate-induced and Apc-induced intestinal tumorigenesis are suppressed in Clec7a mice independently from commensal microbiota.

Transcriptional changes detected in fecal RNA from neonatal dairy calves of different breeds following gastrointestinal disease of varying severity.

Gastrointestinal (GI) disease is a major health concern in preweaned dairy calves. The objective of this fixed cohort study was to use RNA isolated from preweaned Holstein and Jersey heifer calf feces to study the molecular adaptations to variable clinical GI disease. The study was conducted on a commercial calf ranch in the western U.

Effects of a farm-specific fecal microbial transplant (FMT) product on clinical outcomes and fecal microbiome composition in preweaned dairy calves.

Gastrointestinal disease (GI) is the most common illness in pre-weaned dairy calves. Therefore, effective strategies to manipulate the microbiome of dairy calves under commercial dairy operations are of great importance to improve animal health and reduce antimicrobial usage. The objective of this study was to develop a farm-specific FMT product and to investigate its effects on clinical outcomes and fecal microbial composition of dairy calves.

A screening test is not enough to define the prognostic role of cognitive impairment after hip fracture: a short-term prospective study.

Background: Cognitive impairment assessed by easy-to-administer tests successfully predicts function after hip fracture, whereas the prognostic role of additional cognitive evaluations is largely unknown.

Aims: To investigate the capability of further assessments to discriminate cognitive impairment with prognostic relevance in hip-fracture women defined cognitively intact or mildly impaired on the Short Portable Mental Status Questionnaire (SPMSQ).

Methods: We prospectively investigated women with subacute hip fracture admitted to our rehabilitation facility.

Fecal microbiome profiles of neonatal dairy calves with varying severities of gastrointestinal disease.

Gastrointestinal disease (GI) is the most common illness in pre-weaned dairy calves. Studies have associated the fecal microbiome composition with health status, but it remains unclear how the microbiome changes across different levels of GI disease and breeds. Our objective was to associate the clinical symptoms of GI disease with the fecal microbiome.

A Fixed Cohort Field Study of Gene Expression in Circulating Leukocytes From Dairy Cows With and Without Mastitis.

Specifically designed gene expression studies can be used to prioritize candidate genes and identify novel biomarkers affecting resilience against mastitis and other diseases in dairy cattle. The primary goal of this study was to assess whether specific peripheral leukocyte genes expressed differentially in a previous study of dairy cattle with postpartum disease, also would be expressed differentially in peripheral leukocytes from a diverse set of different dairy cattle with moderate to severe clinical mastitis. Four genes were selected for this study due to their differential expression in a previous transcriptomic analysis of circulating leukocytes from dairy cows with and without evidence of early postpartum disease.

Metastatic retroperitoneal tumor from a non-functional neuroendocrine neoplasia of the left ethmoid-nose-orbitary region: Case report and short review of literature.

Introduction: NeuroEndocrine Neoplasms (NENs) are rare and can originate from any epithelial organ. We describe a very rare case of retroperitoneal metastasis from a non-functioning neuroendocrine tumor of the ethmoid region and focus on the various issues related to NENs, from their nosological classification up to the most recent acquisitions in the diagnostic and therapeutic field.

Presentation Of Case: A woman presented with a mass in the right retroperitoneal area that infiltrated liver and kidney.

May predictors of difficulty in thyroid surgery increase the incidence of complications? Prospective study with the proposal of a preoperative score.

Background: Although thyroidectomy is one of the most common surgical procedures performed worldwide, some permanent complications, despite the considerably reducing incidence, may affect dramatically the patients quality of life. The purpose of this study is to evaluate whether factors identified preoperatively and expressed in a score could be predictors of major surgical difficulty during total thyroidectomy and influence the incidence of complications.

Methods: A total of 164 patients who underwent total thyroidectomy were examined.

Sclerosing angiomatoid nodular transformation (SANT) of spleen mimicking a splenic abscess: Case report and review of the literature.

Introduction: SANT of the spleen is a benign lesion that does not recur after splenectomy with unknown etiology.

Presentation Of The Case: We report a case of sclerosing angiomatoid nodular transformation (SANT) of the spleen mimicking a splenic abscess in a patient with imaging studies that failed to differentiate this lesion from other splenic lesions.

Discussion: SANT of the spleen is a rare condition, with only less than 100 cases reported in the literature.

Association of plasma haptoglobin concentration and other biomarkers with bovine respiratory disease status in pre-weaned dairy calves.

We conducted a nested, case-control study of pre-weaned dairy calves ( n = 477; 4 California dairy farms) to assess the association between bovine respiratory disease (BRD) and hematologic biomarkers, including plasma haptoglobin (Hp) and plasma bactericide (PB). At each location, heifer or bull dairy calves were observed 2-4 times per week until confirmed as BRD-positive using parallel interpretation of thoracic ultrasound examination and auscultation. In addition, control calves were enrolled after being confirmed as BRD-negative using ultrasound and auscultation.

Endovascular treatment of ruptured pancreaticoduodenal artery aneurysm: The importance of collateral vessels. A case report.

Introduction: True pancreaticoduodenal artery aneurysm occurrence is infrequent, but it is a fatal disease and accounts for accounts for <2% of all visceral aneurysms.

Presentation Of Case: A 62-year-old man with a two-day history of epigastric pain was admitted at emergency department. CT showed a retroperitoneal haematoma due to a 1.

Retinoic acid induces white adipose tissue browning by increasing adipose vascularity and inducing beige adipogenesis of PDGFRα adipose progenitors.

Formation of beige adipocytes within white adipose tissue enhances energy expenditure, which is a promising strategy to reduce obesity and prevent metabolic symptoms. Vitamin A and its bioactive metabolite, retinoic acid (RA), have regulatory roles in lipid metabolism. Here we report that RA induces white adipose tissue browning via activating vascular endothelial growth factor (VEGF) signaling.

Advancement of thyroid surgery video recording: A comparison between two full HD head mounted video cameras.

Background: The aim of this study was to test two different video cameras and recording systems used in thyroid surgery in our Department. This is meant to be an attempt to record the real point of view of the magnified vision of surgeon, so as to make the viewer aware of the difference with the naked eye vision.

Materials And Methods: In this retrospective study, we recorded and compared twenty thyroidectomies performed using loupes magnification and microsurgical technique: ten were recorded with GoPro 4 Session action cam (commercially available) and ten with our new prototype of head mounted video camera.

THY3 cytology: What surgical treatment? Retrospective study and literature review.

Introduction: THY3 nodules collects 20% of cytological examinations, with a rate of malignancy by about 20-30%, and represent one of the most controversial topics of scientific debate. In fact, differential diagnosis of follicular lesions, is very difficult, due to the inability of cytology to differentiate between adenomas and carcinomas. Surgery represents the only possible diagnostic and therapeutic approach, but on the type of surgery there is still absolute discordance of opinions.

Activation of toll-like receptor-2 by endogenous matrix metalloproteinase-2 modulates dendritic-cell-mediated inflammatory responses.

Matrix metalloproteinase-2 (MMP-2) is involved in several physiological mechanisms, including wound healing and tumor progression. We show that MMP-2 directly stimulates dendritic cells (DCs) to both upregulate OX40L on the cell surface and secrete inflammatory cytokines. The mechanism underlying DC activation includes physical association with Toll-like receptor-2 (TLR2), leading to NF-κB activation, OX40L upregulation on DCs, and ensuing TH2 differentiation.

Standard laparoscopic versus single-incision laparoscopic colectomy for cancer: early results of a randomized prospective study.

Background: Standard laparoscopic colectomy (SLC) for cancer is a safe, feasible, and oncologically effective procedure with better short-term and similar long-term results of open colectomy. Conversely, owing to technical difficulties in colonic resection and full mesenteric dissection, single-incision laparoscopic colectomy (SILC) has been considered unsuitable for oncologic purposes. We compared the technical feasibility and early clinical outcomes of SLC and SILC for cancer.

[Piezosurgery mandibular enostosis: case report].

The bone surgery has always used manual and rotary instruments. The biomedical engineering with ultrasound working principle has given a new surgery instruments, which allow a selective cutting action of bone tissue and the protection of soft tissue. Our case shows an uncommon clinical lesion surgically dangerous for the narrow adjoining of important anatomical structures as the lower alveolar artery and the lower alveolar nerve.

Rab33A: characterization, expression, and suppression by epigenetic modification.

Rab33A, a member of the small GTPase superfamily, is an X-linked gene that is expressed in brain, lymphocytes, and normal melanocytes, but is downregulated in melanoma cells. We demonstrate that in normal melanocytes Rab33A colocalizes with melanosomal proteins and that a constitutively active GTPase mutant suppresses their transport to the melanosomes. In the brain, Rab33A is present throughout the cortex, as well as in the hippocampal CA fields.

Quantitative and dynamic assessment of the contribution of the ER to phagosome formation.

Phagosomes were traditionally thought to originate from an invagination and scission of the plasma membrane to form a distinct intracellular vacuole. An alternative model implicating the endoplasmic reticulum (ER) as a major component of nascent and maturing phagosomes was recently proposed (Gagnon et al., 2002).

[Impact of an integrated treatment approach of the severely injured patients (ISS =/> 16) on hospital mortality and quality of care].

Background: Outcome of severely injured patients is sharply influenced by the level of prehospital and hospital organization.

Objective: To evaluate the impact of the re-organization of the trauma care process on the quality of care and final outcome of major trauma (ISS =/< 16) victims.

Setting: the Emergency Department (ED) of a 1600 bedded tertiary care hospital.

Developmental control of endocytosis in dendritic cells by Cdc42.

Dendritic cells (DCs) developmentally regulate antigen uptake by controlling their endocytic capacity. Immature DCs actively internalize antigen. However, mature DCs are poorly endocytic, functioning instead to present antigens to T cells.
