Carbapenem-resistant Enterobacteriaceae (CRE) has emerged as a global threat to hospitalization patients. Infected pancreatic necrosis (IPN) leads to high risks of CRE infections with increasing mortality. Our study aims to determine the predictors related to 90-day overall mortality of CRE IPN.
We retrospectively reviewed the drug resistance rates and clinical characteristics of CRE IPN patients from January 1, 2016, to January 1, 2021. Independent predictors of mortality were identified via univariate and multivariate analyses.
During the 5-year period, 75 IPN patients suffered from 135 episodes of CRE infections with mortality up to 50.7%. CRE strains were highly resistant (> 50%) to nine of ten common antibiotics, except tigecycline (18%). The most common pathogen was carbapenem-resistant Klebsiella pneumoniae (84 of 135). Lung was the main site of extrapancreatic infections, followed by bloodstream and biliary tract. The independent predictors of mortality were Sequential Organ Failure Assessmenic intervention for CRE IPN.
Grazing behavior is common in patients undergoing bariatric surgery (BS); however, little is known about grazing behavior in operated patients in the long term. We aimed to estimate grazing frequency and its association with weight loss and surgery response in patients who had undergone BS.
This cross-sectional study included 109 patients who had undergone Roux-en-Y gastric bypass at least 5 years previously. They answered questions about socioeconomic factors, surgical information, and adherence to treatment/follow-up. The Rep(eat) questionnaire was used for grazing assessment. Student's t-test and Pearson's chi-square test were used to evaluate differences between groups. Analysis of covariance and partial correlation were used to investigate grazing behavior, and weight loss outcomes were controlled for the elapsed time since BS, healthcare service type, current psychologist care status, and the presence of a constriction ring.
The mean elapsed time since BS was 9.97 ± 2.39 years. Patients with grazing behavior (67%) comprised fewer surgery responders (p = 0.019), had lower total (%TWL, p = 0.005) and excess weight loss (%EWL, p = 0.029), and received less psychological counseling (45.5% vs. 54.5%, p = 0.042). Correlations were found between the presence of grazing and its subtypes and %EWL and %TWL (T = - 0.382, T = - 0.361, p < 0.001; compulsive grazing T = - 0.358, T = - 0.342, p < 0.001, p = 0.001; non-compulsive grazing T = - 0.333, T = - 0.311, p = 0.001, p = 0.003). No significant difference between patients with and without grazing behavior was found for previous/current diagnoses of psychological diseases or dietitian counseling.
Grazing behavior is common in the long-term among patients who have undergone BS and is negatively related to weight loss parameters.

Few bariatric surgery programs exist at safety net hospitals which often serve patients of diverse racial and socioeconomic backgrounds. A bariatric surgery program was developed at a large urban safety net medical center serving a primarily Hispanic population. The purpose of this study was to evaluate safety, feasibility, and first-year outcomes to pave the way for other safety net bariatric programs.
The bariatric surgery program was started at a safety net hospital located in a neighborhood with over twice the national poverty rate. A retrospective review was performed for patient demographics, comorbidities, preoperative diet and exercise habits, perioperative outcomes, and 1-year outcomes including percent total weight lost (%TWL) and comorbidity reduction.
A total of 153 patients underwent laparoscopic sleeve gastrectomy from May 2017 through December 2019. The average preoperative BMI was 47.9kg/m
, and 54% of patients had diabetes. The 1-year follow-up rate was 94%. There were no mortalities and low complication rates. The average 1-year %TWL was 22.8%. Hypertension and diabetes medications decreased in 52% and 55% of patients, respectively. The proportion of diabetic patients with postoperative HbA1c <6.0% was 49%.
This is one of the first reports on the outcomes of a bariatric surgery program at a safety net hospital. This analysis demonstrates feasibility and safety, with no mortalities, low complication rates, and acceptable %TWL and comorbidity improvement. More work is needed to investigate the impacts of race, culture, and socioeconomic factors on bariatric outcomes in this population.

Aside from being highly expressed in muscle, FNDC5 is highly expressed in the brain. The cleaved form of FNDC5 was found in the cerebrospinal fluid as well as in various regions of the brain. Numerous studies suggest that irisin plays a key role in brain metabolism and inflammation regulation. Both the metabolism and inflammation govern stroke outcome, and in a published study, we demonstrated that LFV therapy following middle cerebral artery occlusion significantly reduced innate immune response, improved motor function and infarct volume in reproductively senescent female rats. The observed effect of LFV therapy could be working via irisin, therefore, the current review focuses to understand various aspects of irisin including its mechanism of action on the brain.Mites (Acari) represent important parasites for a diverse range of hosts. Within the Acari, the Prostigmata represent a diverse suborder of the order Trombidiformes with about 20 000 species, including parasitic forms on both vertebrates and invertebrates. Within the Prostigmata, the genus Locustacarus (Heterostigmata Podapolipidae) is particularly known as an intratracheal parasite of bumblebees and grasshoppers. In a survey on prostigmatic mites (Acari Trombidiformes Prostigmata) associated with insects in the eastern parts of Iran, one new species of the endoparasitic Locustacarus was collected associated to the grasshopper Aiolopus thalassinus (Fabricius) (Orthoptera Acrididae). This new species, Locustacarus aiolopi Rahmatzaei & Hajiqanbar n. sp., is described here and compared morphologically with other species of the genus. This new species represents the first record of a grasshopper-associated Locustacarus species in the Palearctic. We further provide a comprehensive review of the global distribution of this genus as well as its host range.Visual object recognition in humans and nonhuman primates is achieved by the ventral visual pathway (ventral occipital-temporal cortex, VOTC), which shows a well-documented object domain structure. An on-going question is what type of information is processed in the higher-order VOTC that underlies such observations, with recent evidence suggesting effects of certain visual features. Combining computational vision models, fMRI experiment using a parametric-modulation approach, and natural image statistics of common objects, we depicted the neural distribution of a comprehensive set of visual features in the VOTC, identifying voxel sensitivities with specific feature sets across geometry/shape, Fourier power, and color. The visual feature combination pattern in the VOTC is significantly explained by their relationships to different types of response-action computation (fight-or-flight, navigation, and manipulation), as derived from behavioral ratings and natural image statistics. These results offer a comprehensive visual feature map in the VOTC and a plausible theoretical explanation as a mapping onto different types of downstream response-action systems.Mechanosensitive ion channels (MSCs) are key molecules in the mechano-electrical transduction of arterial baroreceptors. Among them, acid-sensing ion channel 2 (ASIC2) and transient receptor potential vanilloid subfamily member 1 (TRPV1) have been studied extensively and documented to play important roles. In this study, experiments using aortic arch-aortic nerve preparations isolated from rats revealed that both ASIC2 and TRPV1 are functionally necessary, as blocking either abrogated nearly all pressure-dependent neural discharge. However, whether ASIC2 and TRPV1 work in coordination remained unclear. So we carried out cell-attached patch-clamp recordings in HEK293T cells co-expressing ASIC2 and TRPV1 and found that inhibition of ASIC2 completely blocked stretch-activated currents while inhibition of TRPV1 only partially blocked these currents. Immunofluorescence staining of aortic arch-aortic adventitia from rats showed that ASIC2 and TRPV1 are co-localized in the aortic nerve endings, and co-immunoprecipitation assays confirmed that the two proteins form a compact complex in HEK293T cells and in baroreceptors. Moreover, protein modeling analysis, exogenous co-immunoprecipitation assays, and biotin pull-down assays indicated that ASIC2 and TRPV1 interact directly. In summary, our research suggests that ASIC2 and TRPV1 form a compact complex and function synergistically in the mechano-electrical transduction of arterial baroreceptors. The model of synergism between MSCs may have important biological significance beyond ASIC2 and TRPV1.
Thymic epithelial tumour (TET) is the most common tumour affecting the anterior mediastinum in adults. The cardiac extension is often limited to the pericardium, and intracardiac extension is rare. We present a unique case of encasement and displacement of the left anterior descending coronary artery by the large mediastinal tumour leading to myocardial ischemia.
Our patient is a 28-year-old lady with stage 4 TET. She presented with acute chest pain associated with 12-lead ECG changes and a significant rise in serial troponin I. Multimodality cardiac imaging revealed encasement and displacement of the left anterior descending coronary artery by the large mediastinal tumour. CT-FFR demonstrates evidence of ischemia which would account for her acute presentation. Following detailed MDT discussions between cardiologists, oncologists and cardiothoracic surgeons, the decision was made to treat this lady with palliative chemotherapy. Given the extent of the tumour invasion and failure of the initial therapy, her prognosis and the outcome were poor.
TET could cause atrial compression, myocardial infiltration, and invasion of the pulmonary and caval veins; however, to the best of our knowledge, this is the first case reported of coronary artery displacement and encasement by TET.
