The cytologic diagnosis of inflammation on canine hepatic aspirates can be confounded by neutrophilic infiltrates in the liver of dogs with nodular regeneration, by extramedullary hematopoiesis, and by marked blood contamination.

We aimed to assess the association between neutrophil counts on hepatic cytology and the histopathologic diagnosis in dogs with hepatitis and non-inflammatory hepatopathy. We also sought to determine a cut-off value for the cytologic diagnosis of hepatitis.

In a retrospective blinded pilot study, three observers independently reviewed hepatic aspirates that had corresponding histopathologic examinations performed within 2days. The number of neutrophils per 200 hepatocytes was determined and averaged among observers. Only neutrophils within or directly in contact with a cluster of ≥5 hepatocytes were counted, and only intact hepatocytes within an approximate monolayer were included. Data are presented as the median (range), and the Mann-Whitney U test is used to make comparisonsix or more neutrophils per 200 hepatocytes is highly suggestive of hepatitis.This work investigates aspects of the global sensitivity analysis of computer codes when alternative plausible distributions for the model inputs are available to the analyst. Analysts may decide to explore results under each distribution or to aggregate the distributions, assigning, for instance, a mixture. In the first case, we lose uniqueness of the sensitivity measures, and in the second case, we lose independence even if the model inputs are independent under each of the assigned distributions. Removing the unique distribution assumption impacts the mathematical properties at the basis of variance-based sensitivity analysis and has consequences on result interpretation as well. We analyze in detail the technical aspects. From this investigation, we derive corresponding recommendations for the risk analyst. We show that an approach based on the generalized functional ANOVA expansion remains theoretically grounded in the presence of a mixture distribution. Numerically, we base the construction of the generalized function ANOVA effects on the diffeomorphic modulation under observable response preserving homotopy regression. Our application addresses the calculation of variance-based sensitivity measures for the well-known Nordhaus' DICE model, when its inputs are assigned a mixture distribution. A discussion of implications for the risk analyst and future research perspectives closes the work.A 13-year-old 4.6 kg castrated male Italian Greyhound was presented for evaluation of sneezing, bilateral epistaxis and mucoid nasal discharge of approximately 3 months duration. Severe periodontal disease was noted on physical exam. The patient's CBC was unremarkable. His biochemical profile revealed mild azotemia as well as mild electrolyte abnormalities. Ceftaroline Anti-infection inhibitor Rhinoscopy revealed a tan plaque present in the left dorsal meatus of the nasal cavity. Vigorous flushing yielded granular white particulates suspended in the saline, which were cytologically examined. Marked neutrophilic inflammation, a diverse bacterial population, and organisms consistent with amoebic trophozoites were identified. The remaining fluid was analyzed by PCR and sequencing, and Entamoeba gingivalis was identified. The dog's clinical signs improved dramatically after initiating treatment with clindamycin. Six weeks after diagnosis, a dental cleaning with multiple extractions was performed. Four weeks after the dental procedure, the dog was clinically normal. This report describes the clinical, hematologic, cytologic, and gross findings in a case of Entamoeba gingivalis infection in a dog.

Erythrocyte microcytosis in some dogs with hepatocellular carcinoma (HCC) suggests a derangement in systemic iron. Hepcidin, the master regulator of iron, is secreted by the liver in response to interleukin 6 (IL-6) and/or bone morphogenetic protein 6 (BMP6) and can cause microcytosis.

Pilot study to compare the quantities of hepcidin, IL-6, and BMP6 RNA molecules in archival tumoral (HCC) and adjacent peritumoral (non-HCC) hepatic tissue to determine if they are different between tissue types or associated with microcytosis.

RNA was isolated from formalin-fixed, paraffin-embedded HCC and non-HCC tissue from seven microcytic dogs and four normocytic dogs. Digital RNA counts of hepcidin, IL-6, or BMP6, and six other iron-regulatory genes were determined using the Nanostring nCounter system. The area of blue on each section was digitally evaluated to measure the extent of Prussian blue staining objectively. Parameters were compared between HCC and non-HCC tissue and between microcytic and normocytic groupd determining if iron loading in canine liver is a predisposing factor for HCC.Favipiravir is a potential antiviral medication that has been recently licensed for Covid-19 treatment. In this work, a gadolinium-based magnetic ionic liquid was prepared and used as an extractant in dispersive liquid-liquid microextraction (DLLME) of favipiravir in human plasma. The high enriching ability of DLLME allowed the determination of favipiravir in real samples using HPLC/UV with sufficient sensitivity. The effects of several variables on extraction efficiency were investigated, including type of extractant, amount of extractant, type of disperser and disperser volume. The maximum enrichment was attained using 50 mg of the Gd-magnetic ionic liquid (MIL) and 150 μl of tetrahydrofuran. The Gd-based MIL could form a supramolecular assembly in the presence of tetrahydrofuran, which enhanced the extraction efficiency of favipiravir. The developed method was validated according to US Food and Drug Administration bioanalytical method validation guidelines. The coefficient of determination was 0.9999, for a linear concentration range of 25 to 1.0 × 105 ng/ml. The percentage recovery (accuracy) varied from 99.83 to 104.2%, with RSD values (precision) ranging from 4.07 to 11.84%. The total extraction time was about 12 min and the HPLC analysis time was 5 min. The method was simple, selective and sensitive for the determination of favipiravir in real human plasma.The article discusses the additive manufacturing/3D printing of human skin for advanced applications. Even though this is still in its infancy, additive manufacturing has the potential to revolutionize the field of dermatology and cosmetology.

Enteral nutrition (EN) in critically ill patients requiring vasoactive drug (VAD) support is controversial. This study assesses the tolerability and safety of EN in such patients.

This prospective observational study was conducted in 23 intensive care units (ICUs) over 30 months. Inclusion criteria were a need for VADs and/or mechanic circulatory support (MCS) over a minimum of 48 h, a need for ≥48 h of mechanical ventilation, an estimated life expectancy >72 h, and ≥72 h of ICU stay. Patients with refractory shock were excluded. EN was performed according to established protocols during which descriptive, daily hemodynamic and efficacy, and safety data were collected. An independent research group conducted the statistical analysis.

Of 200 patients included, 30 (15%) required MCS and 145 (73%) met early multiorgan dysfunction criteria. Mortality was 24%. Patients needed a mean dose of norepinephrine in the first 48 h of 0.71 mcg/kg/min (95% CI, 0.63-0.8) targeting a mean arterial pressure of 68 mm Hg (95% CI, 67-70) during the first 48 h. EN was started 34 h (95% CI, 31-37) after ICU admission. Mean energy and protein delivered by EN/patient/day were 1159 kcal (95% CI, 1098-1220) and 55.6 g (95% CI, 52.4-58.7), respectively. Daily energy balance during EN/patient/day was -432 (95% CI, -496 to -368). One hundred and fifty-four (77%) patients experienced EN-related complications. However, severe complications, such as mesenteric ischemia, were recorded in only one (0.5%) patient.

EN in these patients seems feasible, safe, and unrelated to serious complications. Reaching the energy target only through EN is difficult.

There have been no standard protocols of oral exercises for maintaining and improving oral function for people with dementia.

This study aimed to determine the effects of home-based oral exercises on the oral function of people with mild to moderate dementia.

Twenty-two participants at King Chulalongkorn Memorial Hospital were randomly assigned to the exercise group (n=11) or control group (n=11). The exercise group was instructed to do three home-based oral exercises, consisting of tongue-strengthening, oral diadochokinesis (ODK) and mouth-opening exercises, for 3months, while the control group received advice on oral health care. The maximum tongue pressure (MTP) was the primary outcome. MTP, ODK rates of /pa/, /ta/, /ka/, modified water swallowing test (MWST) and oral moisture were measured at baseline, and after 1, 2 and 3months of training. The generalised estimating equation analysis was used to evaluate the effects of oral exercises on the oral function.

The MTP and all ODK rates in the exercise group were significantly increased after 3months of training. There were significant interaction effects between time and intervention in MTP and all ODK rates. No significant interaction effects between time and intervention in oral moisture were found. The MWST scores in both groups did not change through the end of study, and no adverse effects were reported.

Home-based oral exercises were found to be effective for improving tongue strength and tongue-lip motor function in people with mild to moderate dementia.

Several studies reported that astrocytes support neuronal communication by the release of gliotransmitters, including ATP and glutamate. Astrocytes also play a fundamental role in buffering extracellular glutamate in the synaptic cleft, thus limiting the risk of excitotoxicity in neurons. We previously demonstrated that extracellular tau oligomers (ex-oTau), by specifically targeting astrocytes, affect glutamate-dependent synaptic transmission via a reduction in gliotransmitter release. The aim of this work was to determine if ex-oTau also impair the ability of astrocytes to uptake extracellular glutamate, thus further contributing to ex-oTau-dependent neuronal dysfunction.

Primary cultures of astrocytes and organotypic brain slices were exposed to ex-oTau (200 nM) for 1h. Extracellular glutamate buffering by astrocytes was studied by Na

imaging; electrophysiological recordings; high-performance liquid chromatography; Western blot and immunofluorescence. Experimental paradigms avoiding ex-oTau internalit both intracellular and extracellular levels. The net effect was dysregulated glutamate signalling in terms of both release and uptake that relied on reduced expression of glutamate-transporter-1, altered function and localisation of NKA1A1, and NKA1A2. Consequently, Na+ gradients and all Na+ -dependent transports were affected.
