to the ones obtained by injecting higher amounts and it reduces the number of cement leaks and further complications.

The questionnaire Hospital for Special Surgery Shoulder Surgery Expectations Survey (HSS-ES) is a tool used to assess the preoperative expectations of patients with shoulder pathologies. The purpose of this study is to translate, culturally adapt, and validate the Spanish version of the HSS-ES questionnaire to assess preoperative expectations in Spanish-speaking patients.

Questionnaire validation study, using a structured method where a survey-type tool was processed, evaluated and validated. The study involved 70 patients from the shoulder surgery outpatient clinic of a tertiary care hospital, with shoulder pathologies requiring surgery.

The version of the questionnaire translated into Spanish presented a very good internal consistency with a Cronbach’s Alpha of 0.94 and a very good reproducibility with an Intraclass Correlation Coefficient (ICC) of 0.99.

The HSS-ES questionnaire presents an adequate intragroup validation and a strong intergroup correlation according to the internal consistency analysis of the questionnaire and the ICC. Therefore, it is considered an adequate questionnaire to use in the Spanish-speaking population.

Tissue resident memory T cells have unique transcriptome characteristics, and their presence in peripheral tissues is regulated by many factors. TRM cells residing in different tissues often express different surface markers. In addition to CD8+ and CD4+ T cells, which are the best-characterized T cells, Treg cells and various innate T cells can reside in nonlymphoid tissues. Many recent studies have shown that tissue resident memory T cells play indispensable roles in tumor immunity and allergic diseases. This paper reviews the differentiation, regulation, variety and function of TRM cells and the roles they play in skin diseases, including cutaneous melanoma and psoriasis.Increased international travel and importation of animals brings with it the potential for spread of infectious diseases. This report details a case in which an 8-month-old male mixed breed dog died shortly after arrival to the United States from complications secondary to spirocercosis, despite having been deemed healthy and approved for international travel. Four weeks following arrival, the dog developed mild tachypnea and diarrhea. Physical examination revealed moderate pyrexia with generalized cerebellar ataxia, moderate anemia, a mature neutrophilia, and severe panhypoproteinemia. Packed red blood cells were administered. The dog was diagnosed with pyothorax and decompensated with septic shock shortly thereafter. Necropsy revealed severe transmural esophagitis with intralesional Spirocerca lupi. Evaluation of the brain revealed cerebellar hypoplasia, and polymerase chain reaction of brain tissue was positive for canine parvovirus. Despite receiving a clean bill of health in its country of origin, this patient ultimately had evidence of 2 different infectious processes that pre-dated its arrival into the United States. While neither of these diseases posed a significant public health risk, this case highlights the role veterinarians play before and after international travel as important barriers against the spread of exotic diseases, and emphasizes that maintaining vigilance is paramount to that task.Brachyspira hyodysenteriae, an etiologic agent of swine dysentery (SD), is known for causing colitis. Although some aspects of colonic defenses during infection have been described previously, a more comprehensive picture of the host and microbiota interaction in clinically affected animals is required. This study aimed to characterize multiple aspects of colonic innate defenses and microbiome factors in B. hyodysenteriae-infected pigs that accompany clinical presentation of hemorrhagic diarrhea. We examined colonic mucus barrier modifications, leukocyte infiltration, cathelicidin expression, as well as microbiome composition. We showed that B. hyodysenteriae infection caused microscopic hemorrhagic colitis with abundant neutrophil infiltration in the colonic lamina propria and lumen, with minor macrophage infiltration. Mucus hypersecretion with abundant sialylated mucus in the colon, as well as mucosal colonization by [Acetivibrio] ethanolgignens, Lachnospiraceae, and Campylobacter were pathognomonic of B. hyodysenteriae infection. These findings demonstrate that B. hyodysenteriae produces clinical disease through multiple effects on host defenses, involving alterations of mucosal innate immunity and microbiota. Given that B. hyodysenteriae is increasingly resistant to antimicrobials, this understanding of SD pathogenesis may lead to future development of non-antibiotic and anti-inflammatory alternative therapeutics.Yersinia enterocolitica (Y. enterocolitica) is a gastrointestinal pathogen that is distributed worldwide, involved in systemic, extraintestinal and invasive infections in immunocompromised patients. Establishment of antibiotic resistance in the pathogen has produced a need for new antibacterial agents. The purpose of this study was to elucidate antibacterial mechanism of protocatechualdehyde (PCA) extracted from the roots of Salvia miltiorrhiza towards Y. enterocolitica, and to investigate effects of PCA on key virulence factors associated with human infection. Present results indicated that PCA exerted its antibacterial activity against Y. enterocolitica mainly by the rapid rise of intracellular reactive oxygen species, leading to change in permeability and integrity of cell membrane, and ultimately decline of membrane potential and intracellular ATP. Furthermore, scanning electron microscopic analysis revealed that Y. enterocolitica presented gradually shrinkage in length and partial wrinkles upon PCA treatment. PCA also effectively decreased motility, biofilm formation, quorum sensing in a dose-dependent manner without affecting bacterial growth. Further, at SICs, PCA substantially suppressed the adhesion and invasion of Y. enterocolitica to HT-29 cells and the downregulation of essential virulence factor-encoding genes unveiled impaired virulence. Overall, the findings revealed the potential of PCA as an alternative antibacterial agent to combat Y. enterocolitica contamination and infections.

It is unclear whether patients with asthma benefit from stepping up to high-dose inhaled corticosteroids (ICSs).

To determine the effectiveness of stepping up to high-dose ICSs.

A historic cohort study of patients with asthma (≥13 years old), identified from 2 large UK electronic medical record databases, was conducted. Patients who remained on medium-dose ICSs were compared with those who stepped up from medium- to high-dose ICSs, whereas patients who stepped up from low- to medium-dose ICSs were compared with those who stepped up from low- to high-dose ICSs. Time to first severe exacerbation (primary outcome) between treatment groups was compared using multivariable Cox proportional hazards models, and the number of exacerbations and antibiotics courses was analyzed using negative binomial regression. Inverse probability of treatment weighting was used to handle confounding.

The mean follow-up time to first exacerbation was 2.7 ± 2.7 years for those who remained on stable medium-dose ICSs and 2.0 ± in preventing future asthma exacerbations.The first report of food allergy desensitization was in 1908, at least a few years before the first published description of a diagnostic test for food allergy. It has taken almost 100 years for food allergy to move from passive management of avoidance to a more proactive approach including prevention and treatment. In parallel, this has been matched by recognition of eosinophil gastrointestinal diseases, which were first described in the 1980s (although eosinophilic esophagitis was itself described in 1978). As we celebrate 10 years of The Journal of Allergy and Clinical Immunology In Practice, we take the opportunity to look into the future and speculate how our practice may develop over the next decade.Preclinical models demonstrate that nearly all anesthetics cause widespread neuroapoptosis in the developing brains of infant rodents and non-human primates. Anesthesia-induced developmental apoptosis is succeeded by prolonged neuropathology in the surviving neurons and lasting cognitive impairments, suggesting that anesthetics interfere with the normal developmental trajectory of the brain. selleck inhibitor However, little is known about effects of anesthetics on stereotyped axonal pruning, an important developmental algorithm that sculpts neural circuits for proper function. Here, we proposed that neonatal ketamine exposure may interfere with stereotyped axonal pruning of the infrapyramidal bundle (IPB) of the hippocampal mossy fiber system and that impaired pruning may be associated with alterations in the synaptic transmission of CA3 neurons. To test this hypothesis, we injected postnatal day 7 (PND7) mouse pups with ketamine or vehicle over 6 h and then studied them at different developmental stages corresponding to IPB pruning (PND20-40). Immunohistochemistry with synaptoporin (a marker of mossy fibers) revealed that in juvenile mice treated with ketamine at PND7, but not in vehicle-treated controls, positive IPB fibers extended farther into the stratum pyramidale of CA3 region. Furthermore, immunofluorescent double labeling for synaptoporin and PSD-95 strongly suggested that the unpruned IPB caused by neonatal ketamine exposure makes functional synapses. Importantly, patch-clamp electrophysiology for miniature excitatory postsynaptic currents (mEPSCs) in acute brain slices ex vivo revealed increased frequency and amplitudes of mEPSCs in hippocampal CA3 neurons in ketamine-treated groups when compared to vehicle controls. We conclude that neonatal ketamine exposure interferes with normal neural circuit development and that this interference leads to lasting increase in excitatory synaptic transmission in hippocampus.Our previous study suggests that hippocampal cysteinyl leukotriene receptor 1 (CysLT1R) could be involved in depression. Herein we hypothesize that CysLT1R may regulate depression by affecting synaptic glutamate cycling based on existence of CysLT1R in the astrocytes that participate in occurrence of depression. We found that CysLT1R expression was significantly increased in the astrocyte of chronic unpredictable mild stress (CUMS)-induced depression-like mice, CysLT1R astrocyte-specific conditional knockout (AcKO) significantly improved depression-like behaviors, as indicated by decreased immobility time in the forced swimming test and tail suspension test and increased sucrose preference in the sucrose preference test, and knockdown of CysLT1R in the astrocyte of dentate gyrus (DG), the region with the most significant increase of CysLT1R in the astrocyte of depression-like mice, produced similar effects. Correspondingly, overexpression of CysLT1R in the astrocyte of DG induced depression-like behaviors in mice.
