Excessive Preoperative Testing in Otolaryngology: A Retrospective Comparison of Primary Care and Perioperative Providers.

Objective: To assess the association between provider type (primary care provider [PCP] or perioperative provider) and excessive preoperative testing.

Study Design: Cross-sectional study.

Setting: Academic medical center.

The dermatopathologist-patient consultation program: A pilot study on patient perspectives and interest.

Background: Despite the integral contribution of dermatopathologists in diagnosing skin lesions, their role often remains unclear to patients, likely due to little face-to-face interaction. More healthcare systems have begun introducing patient-pathologist consultation programs that allow patients to discuss results with a pathologist and view tissue under a microscope. To our knowledge, only one study has been published exploring patient perspectives of these programs and no studies exist regarding interest in dermatopathology.

Management of tinea capitis in infants and children in the United States: A national survey of pediatric dermatologists.

This study aimed to evaluate the current management of tinea capitis in the United States, specifically focusing on patients aged 0-2 months, 2 months to 2 years, and 2 years to 18 years. An online survey, distributed through the Pediatric Dermatology Research Alliance and the Society of Pediatric Dermatology, revealed the following preferences: fluconazole for those under 2 months, griseofulvin for those aged 2 months to 2 years, and terbinafine for those aged 2 years and older. There exists inter-provider variation in tinea capitis treatment regimens within the pediatric dermatology community.

Antimicrobial Effect of Cannabidiol on Intracellular .

, the etiologic agent of tuberculosis (TB), has killed nearly one billion people during the last two centuries. Nowadays, TB remains a major global health problem ranked among the top 10 causes of death worldwide. One of the main challenges in developing new strategies to fight TB is focused on reducing the duration and complexity of drug regimens.

Fever, Cognitive Decline, and Multifocal T2 Hyperintensities on Brain MRI: A Case Report of Cytokine Release Syndrome.

Cytokine release syndrome (CRS) is a systemic inflammatory response characterized by fever, constitutional symptoms, and multiorgan dysfunction. While most commonly associated with immunotherapy, CRS can also be incited by infections or drugs. This case details the presentation and evaluation of a 71-year-old woman with a history of primary myelofibrosis and breast cancer who presented with acute onset of altered mental status.

Circulating Monocyte-Like Myeloid Derived Suppressor Cells and CD16 Positive Monocytes Correlate With Immunological Responsiveness of Tuberculosis Patients.

Alterations of myeloid cell populations have been reported in patients with tuberculosis (TB). In this work, we studied the relationship between myeloid-derived suppressor cells (MDSC) and monocytes subsets with the immunological responsiveness of TB patients. Individuals with active TB were classified as low responders (LR-TB) or high responders (HR-TB) according to their T cell responses against a cell lysate of (-Ag).

PGE2 displays immunosuppressive effects during human active tuberculosis.

Prostaglandin E2 (PGE2), an active lipid compound derived from arachidonic acid, regulates different stages of the immune response of the host during several pathologies such as chronic infections or cancer. In fact, manipulation of PGE2 levels was proposed as an approach for countering the Type I IFN signature of tuberculosis (TB). However, very limited information regarding the PGE2 pathway in patients with active TB is currently available.

IL-12 DNA Displays Efficient Adjuvant Effects Improving Immunogenicity of Ag85A in DNA Prime/MVA Boost Immunizations.

() infection is one of the leading causes of death worldwide. The Modified Vaccinia Ankara (MVA) vaccine vector expressing the mycobacterial antigen 85A (MVA85A) was demonstrated to be safe, although it did not improve BCG efficacy, denoting the need to search for improved tuberculosis vaccines. In this work, we investigated the effect of IL-12 DNA -as an adjuvant- on an Ag85A DNA prime/MVA85A boost vaccination regimen.

Neutrophil autophagy during human active tuberculosis is modulated by SLAMF1.

Neutrophils infected with () predominate in tuberculosis patients' lungs. Neutrophils phagocytose the pathogen, but the mechanism of pathogen elimination is controversial. Macroautophagy/autophagy, a crucial mechanism for several neutrophil functions, can be modulated by immunological mediators.

IFN-γ and IgG responses to Mycobacterium tuberculosis latency antigen Rv2626c differentiate remote from recent tuberculosis infection.

Tuberculin skin test (TST) and IFN-γ release assays are currently used to detect Mycobacterium tuberculosis (Mtb) infection but none of them differentiate active from latent infection (LTBI). Since improved tests to diagnose Mtb infection are required, we studied the immune response to Mtb latency antigen Rv2626c in individuals exposed to the bacteria during different periods. Tuberculosis patients (TB), TB close contacts (CC: subjects exposed to Mtb for less than three months) and healthcare workers (HW: individuals exposed to Mtb at least two years) were recruited and QuantiFERON (QFT) assay, TST and IFN-γ secretion to Rv2626c were analyzed.

The Non-synonymous rs763780 Single-Nucleotide Polymorphism in IL17F Gene Is Associated With Susceptibility to Tuberculosis and Advanced Disease Severity in Argentina.

Th17 lymphocytes, that produce IL17A, IL17F, and IL22, play a crucial role during the immune response against () infection. Whereas, the contribution of IL17A in immunity to tuberculosis is usually accepted, the role of IL17F has been scarcely studied so far. The aim of this work was to evaluate the existence of a potential association of the non-synonymous variant rs763780 SNP of the gene with human tuberculosis.

Nanotechnology in Tuberculosis: State of the Art and the Challenges Ahead.

Tuberculosis (TB) remains as the second most-deadly infection right behind the HIV/AIDS. Actually, in 2016, TB incidence was estimated in 10.4 million cases.

The IFNG rs1861494 Single Nucleotide Polymorphism Is Associated with Protection against Tuberculosis Disease in Argentina.

Interferon gamma (IFNG) plays a key role during () infection, and several polymorphisms located in its gene are associated with risk of tuberculosis in diverse populations. Nevertheless, the genetic resistance/susceptibility to tuberculosis in Argentina is unknown. The rs1861494 polymorphism (G→A) was reported to alter the binding of transcription factors to this region, influencing IFNG production.

Animal-assisted psychotherapy for young people with behavioural problems in residential care.

The aim of this study was to evaluate the impact of an animal-assisted psychotherapy (AAP) programme on clinical symptoms, personal adjustment, and adaptive skills in a group of adolescents in residential care who had experienced childhood trauma and who presented mental health problems and difficulties adapting to the care home environment. The 87 participants (M  = 15.17, SD = 1.

IL17A augments autophagy in Mycobacterium tuberculosis-infected monocytes from patients with active tuberculosis in association with the severity of the disease.

During mycobacterial infection, macroautophagy/autophagy, a process modulated by cytokines, is essential for mounting successful host responses. Autophagy collaborates with human immune responses against Mycobacterium tuberculosis (Mt) in association with specific IFNG secreted against the pathogen. However, IFNG alone is not sufficient to the complete bacterial eradication, and other cytokines might be required.

The IL-17A rs2275913 single nucleotide polymorphism is associated with protection to tuberculosis but related to higher disease severity in Argentina.

Mycobacterium tuberculosis (Mtb) causes nearly 10 millions of new tuberculosis disease cases annually. However, most individuals exposed to Mtb do not develop tuberculosis, suggesting the influence of a human genetic component. Here, we investigated the association of the rs2275913 SNP (G → A) from IL-17A and tuberculosis in Argentina by a case-control study.

Promoting psychosocial adaptation of youths in residential care through animal-assisted psychotherapy.

The goal of this study was to examine the influence of animal-assisted psychotherapy (AAP) on the psychosocial adaptation of a group of adolescents in residential care who had suffered traumatic childhood experiences and who presented with mental health problems. This study recruited 63 youths (mean age=15.27, SD=1.

A Mycobacterium tuberculosis Dormancy Antigen Differentiates Latently Infected Bacillus Calmette-Guérin-vaccinated Individuals.

IFN-γ release assays (IGRAs) are better indicators of Mycobacterium tuberculosis infection than the tuberculin skin test (TST) in Bacillus Calmette-Guérin (BCG)-vaccinated populations. However, IGRAs do not discriminate active and latent infections (LTBI) and no gold standard for LTBI diagnosis is available. Thus, since improved tests to diagnose M.

Secretory Leukocyte Protease Inhibitor (SLPI) expression downregulates E-cadherin, induces β-catenin re-localisation and triggers apoptosis-related events in breast cancer cells.

Background Information: Epithelial cadherin (E-cadherin) is involved in cell-cell adhesion through its extracellular domain, whereas the intracellular domain interacts with adaptor proteins, i.e. β-catenin, links E-cadherin to the actin cytoskeleton and participates in signal transduction events.

Anti-tumor effect of SLPI on mammary but not colon tumor growth.

Secretory leukocyte protease inhibitor (SLPI) is a serine protease inhibitor that was related to cancer development and metastasis dissemination on several types of tumors. However, it is not known the effect of SLPI on mammary and colon tumors. The aim of this study was to examine the effect of SLPI on mammary and colon tumor growth.

Serine leucocyte proteinase inhibitor-treated monocyte inhibits human CD4(+) lymphocyte proliferation.

Serine leucocyte proteinase inhibitor (SLPI) is the main serine proteinase inhibitor produced by epithelial cells and has been shown to be a pleiotropic molecule with anti-inflammatory and microbicidal activities. However, the role of SLPI on the adaptive immune response is not well established. Therefore, we evaluated the effect of SLPI on lymphocyte proliferation and cytokine production.

Immunotherapy with SLPI over-expressing mammary tumor cells decreases tumor growth.

We have demonstrated previously that the inoculation of murine mammary tumor cells genetically modified to express high levels of secretory leukocyte protease inhibitor (2C1) do not develop tumors in immunocompetent mice and these cells are more prone to apoptosis than control cells. The aim of the present study was to evaluate the role of the adaptive immune response in the lack of tumor growth of 2C1 cells and the possibility of using these cells for immunotherapy. The s.

Neutrophil elastase treated dendritic cells promote the generation of CD4(+)FOXP3(+) regulatory T cells in vitro.

We have previously shown that neutrophilic elastase converts human immature dendritic cells (DCs) into TGF-β secreting cells and reduces its allostimulatory ability. Since TGF-β has been involved in regulatory T cells (Tregs) induction we analyzed whether elastase or neutrophil-derived culture supernatant treated DCs induce CD4(+)FOXP3(+) Tregs in a mixed lymphocyte reaction (MLR). We found that elastase or neutrophil-derived culture supernatant treated DCs increased TGF-β and decreased IL-6 production.
