BackgroundSarcoidosis is an inflammatory disease that affects multiple organs. Cell analysis from bronchoalveolar lavage fluid (BALF) is a valuable tool in the diagnostic workup and differential diagnosis of sarcoidosis. Besides the expansion of lymphocyte expression-specific receptor segments (Vα2.3 and Vβ22) in some patients with certain HLA types, the relation between sarcoidosis susceptibility and BAL cell populations’ quantitative levels is not well-understood.MethodsQuantitative levels defined by cell concentrations of BAL cells and CD4+/CD8+ ratio were evaluated together with genetic variants associated with sarcoidosis in 692 patients with extensive clinical data. Genetic variants associated with clinical phenotypes, Löfgren’s syndrome (LS) and non-Löfgren’s syndrome (non-LS), were examined separately. An association test via linear regression using an additive model adjusted for sex, age, and correlated cell type was applied. To infer the biological function of genetic associations, enrichment analysis of expression quantitative trait (eQTLs) across publicly available eQTL databases was conducted.ResultsMultiple genetic variants associated with sarcoidosis were significantly associated with quantitative levels of BAL cells. Specifically, LS genetic variants, mainly from the HLA locus, were associated with quantitative levels of BAL macrophages, lymphocytes, CD3+ cells, CD4+ cells, CD8+ cells, CD4+/CD8+ ratio, neutrophils, basophils, and eosinophils. Non-LS genetic variants were associated with quantitative levels of BAL macrophages, CD8+ cells, basophils, and eosinophils. eQTL enrichment revealed an influence of sarcoidosis-associated SNPs and regulation of gene expression in the lung, blood, and immune cells.ConclusionGenetic variants associated with sarcoidosis are likely to modulate quantitative levels of BAL cell types and may regulate gene expression in immune cell populations. Thus, the role of sarcoidosis-associated gene-variants may be to influence cellular phenotypes underlying the disease immunopathology.

ObjectivesHigh frequency of antimicrobial prescription and the nature of prolonged illness in COVID-19 increases risk for complicated bacteriuria and antibiotic resistance. We investigated risk factors for bacteriuria in the ICU and the correlation between antibiotic treatment and persistent bacteria.MethodsWe conducted a prospective longitudinal study with urine from indwelling catheters of 101 ICU patients from Uppsala University Hospital, Sweden. Samples were screened and isolates confirmed with MALDI-TOF and whole genome sequencing. Isolates were analyzed for AMR using broth microdilution. Clinical data were assessed for correlation with bacteriuria.ResultsLength of stay linearly correlated with bacteriuria (R2 = 0.99, p ≤ 0.0001). 90% of patients received antibiotics, primarily the beta-lactams (76%) cefotaxime, piperacillin-tazobactam, and meropenem. We found high prevalence of Enterococcus (42%) being associated with increased cefotaxime prescription. Antibiotic-susceptible E. coli were found to cause bacteriuria despite concurrent antibiotic treatment when found in co-culture with Enterococcus.ConclusionLonger stays in ICUs increase the risk for bacteriuria in a predictable manner. Likely, high use of cefotaxime drives Enterococcus prevalence, which in turn permit co-colonizing Gram-negative bacteria. Our results suggest biofilms in urinary catheters as a reservoir of pathogenic bacteria with the potential to develop and disseminate AMR.

Background: In order to tailor more effective interventions and minimize the burden of chronic pain, it is critical to identify the interaction and contribution of social and psychological factors in pain. One of the important psychological factors in pain management is related to the choice of pain coping strategies in chronic pain patients. Social resources, including family caregivers’ pain attitudes-beliefs, can influence pain coping strategies in chronic pain patients. Moreover, one key factor that may intervene in the relationship between caregivers’ pain attitudes-beliefs and the patients’ coping strategies is the emotion regulation strategies. Therefore, the present study aimed to investigate the mediating role of emotion regulation strategies of chronic pain patients and their family caregivers on the association between caregivers’ pain attitudes-beliefs and pain coping strategies of chronic pain patients.Methods: We recruited 200 chronic musculoskeletal pain patients and their family caregivers. Chronic pain patients responded to measures of pain coping and emotion regulation strategies while family caregivers completed questionnaires related to their attitude toward pain and emotion regulation of themselves.Results: There is an association between caregivers’ pain attitudes-beliefs and pain coping strategies in patients with chronic musculoskeletal. Moreover, the structural equation modeling revealed that the emotion regulation of both patients and family caregivers mediate the relationship between the caregivers’ pain attitudes-beliefs and pain coping strategies of patients with chronic musculoskeletal.Conclusions: The social context of pain, including the effect of family caregivers’ responses to the patient’s pain, is a critical pain source that is suggested to affect coping strategies in patients. These findings suggest an association between pain attitudes-beliefs in family caregivers and pain coping strategies in patients. Moreover, these results showed that the emotion regulation of both patients and their family caregivers mediates this association.

Published: February 2023

BackgroundCough associated headache is the most common symptom in Chiari malformation type 1 (CM1). However, its pathophysiology and treatment are not clear. The aim of this study was to investigate the relationship between optic nerve sheath diameter (ONSD), an indicator of intracranial pressure, and headache and to investigate its predictive value on postoperative outcome.MethodsIn symptomatic CM1 patients, craniovertebral junction morphometric measurements and ONSD measurements were made from preoperative MR images, and headache intensities and characteristics were evaluated. After different surgical procedures, the clinical characteristics of the patients were evaluated according to the Chicago Chiari Outcome Scale, the change in headache intensity was assessed and the relationship with ONSD was evaluated.ResultsPreoperative headache intensity was significantly correlated with ONSD measurement (p &lt; 0.01). Modified clivoaxial angle and ONSD were independent predictors of postoperative clinical outcome (p &lt; 0.01). The procedure that achieved the greatest surgical enlargement of the foramen Magnum stenosis provided the best clinical outcome. Postoperative reduction in headache intensity and ONS diameter were correlated (p &lt; 0.01).ConclusionThe fact that ONSD is found to be wide in the preoperative period in CM1 patients indicates that the intracranial pressure is permanently high. This diameter increase is correlated with headache and is a valuable guide in the selection of the appropriate treatment method.

IntroductionTea is the main raw material for preparing tea wine.MethodsIn this research, four types of tea wine were prepared using different categories of tea leaves, including green tea, oolong tea, black tea, and dark tea, and the comparative study looking their physicochemical, sensorial, and antioxidant profiles were carried out.ResultsThe dynamic changes of total soluble solids, amino acids and ethanol concentrations, and pH were similar in four tea wines. The green tea wine (GTW) showed the highest consumption of total soluble solids and amino acids, and produced the highest concentrations of alcohol, malic, succinic, and lactic acid among all tea wines. The analysis of volatile components indicated the number and concentration of esters and alcohols increased significantly after fermentation of tea wines. GTW presented the highest volatile concentration, while oolong tea wine (OTW) showed the highest number of volatile compounds. GTW had the highest total catechins concentration of 404 mg/L and the highest ABTS value (1.63 mmol TEAC/mL), while OTW showed the highest DPPH value (1.00 mmol TEAC/mL). Moreover, OTW showed the highest score of sensory properties.DiscussionTherefore, the types of tea leaves used in the tea wine production interfere in its bioactive composition, sensorial, and antioxidant properties.

PurposeTo evaluate the safety and efficacy of stereotactic ablative brachytherapy (SABT) as a salvage therapy for patients with recurrent chest wall cancer (rCWC) who have previously received external beam radiotherapy (EBRT) or surgery.Materials and methodsBetween November 2013 and October 2020, a total of 130 patients (including 75 men with a median age of 63 years) with rCWC treated with SABT were enrolled in this multicenter retrospective study. There were 97 cases of non-small-cell lung carcinoma, 24 cases of breast cancer, and 9 cases of thymic cancer. Of the patients included, 102 patients previously received surgery and 58 patients received EBRT, with systemic treatment progressing after recurrence. None of them were suitable or refused to undergo salvage EBRT or surgery again.ResultsDuring the 22 (4–70)-month median patient follow-up, 59 patients died. The local control (LC) rates at 6, 12, 24, and 36 months were 88.3%, 74.3%, 50.4%, and 36.7%, respectively. The 1-, 2- and 3-year survival rates were 85%, 56%, and 42%, respectively. The median overall survival was 26 months (95% CI, 18.9–33.1 months). The pain relief rate was 81%, and the median to remission time was 10 days. Univariate and multivariate analyses showed that independent prognostic factors for LC included tumor size and postoperative D90. On the other hand, independent prognostic factors for survival include the Karnofsky performance status (KPS) score, tumor size, and D90 19 patients (14.6%) developed grade I/II skin reaction complications. No grade III or severer complications occurred.ConclusionSABT is safe and effective as a salvage therapy for rCWC following EBRT/surgery. For patients with a KPS score greater than 80, prescribed dose greater than 130 Gy, and tumor size less than 4 cm may bring better results.

Published: February 2023

ObjectiveTo analyze the ultrasonographic features of pharyngoesophageal diverticulum (PED) mimicking thyroid nodules and to explore the clinical value of ultrasonography in the diagnosis of PED.MethodThe sonographic findings of 68 patients with PED were retrospectively reviewed. According to the diverticulum echo intensity characteristics, the lesions were divided into solid nodular diverticulum, gas-containing nodular diverticulum, liquid-containing nodular diverticulum, and atypical diverticular changes; and the ultrasonographic manifestations were compared among the four groups.Results30/68 were solid nodular diverticula. The diverticulum cavity was oval or elliptic with a clear border, and the diverticulum wall suggested exhibited a typical hyper-hypo-hyper-echogenic pattern. The diverticulum wall and esophageal wall were seen to be continuous if multiple sections were scanned, and hypoechoic walls showed punctate blood flow. 29/68 diagnosed with air-containing nodular diverticulum, lesions appeared with gas-like hyper-echogenicity internally, with some amount of gas and change in the tail pattern during swallowing. 6/68 patients were diagnosed with liquid-containing nodular diverticulum, and the main ultrasonic manifestations were an anechoic internal diverticulum cavity that was clearly bounded from the thyroid but continuous with the esophageal wall, with a typical hyper-hypo-echoless pattern from the outside to the inside. Another 3/68 were found to have atypical diverticular changes, regional convexities of the esophageal wall with unfashioned nodules. The convex segment was continuous with the hyper-hypo-echogenic esophageal wall and could be seen on slitting scanning.ConclusionOverall, PEDs mimicking thyroid nodules have specific ultrasonographic features. Familiarity with them can avoid missed diagnoses and misdiagnoses.

BackgroundColorectal cancer (CRC) has the third-highest incidence and second-highest mortality rate of all cancers worldwide. Early diagnosis and screening of CRC have been the focus of research in this field. With the continuous development of artificial intelligence (AI) technology, AI has advantages in many aspects of CRC, such as adenoma screening, genetic testing, and prediction of tumor metastasis.ObjectiveThis study uses bibliometrics to analyze research in AI in CRC, summarize the field’s history and current status of research, and predict future research directions.MethodWe searched the SCIE database for all literature on CRC and AI. The documents span the period 2002-2022. we used bibliometrics to analyze the data of these papers, such as authors, countries, institutions, and references. Co-authorship, co-citation, and co-occurrence analysis were the main methods of analysis. Citespace, VOSviewer, and SCImago Graphica were used to visualize the results.ResultThis study selected 1,531 articles on AI in CRC. China has published a maximum number of 580 such articles in this field. The U.S. had the most quality publications, boasting an average citation per article of 46.13. Mori Y and Ding K were the two authors with the highest number of articles. Scientific Reports, Cancers, and Frontiers in Oncology are this field’s most widely published journals. Institutions from China occupy the top 9 positions among the most published institutions. We found that research on AI in this field mainly focuses on colonoscopy-assisted diagnosis, imaging histology, and pathology examination.ConclusionAI in CRC is currently in the development stage with good prospects. AI is currently widely used in colonoscopy, imageomics, and pathology. However, the scope of AI applications is still limited, and there is a lack of inter-institutional collaboration. The pervasiveness of AI technology is the main direction of future housing development in this field.

ObjectivePrimary spinal anaplastic ependymoma (PSAE) is an extremely rare disease. We aim to report the largest PSAE cohort, evaluate the treatments, and investigate the prognostic factors for progression-free survival (PFS).MethodsClinical data collected from the authors’ institute and literature articles were pooled and described. Survival analysis and multivariable Cox regression analysis were performed to evaluate therapies and investigate prognostic factors for PFS.ResultsOur cohort included 22 females and 16 males, with a median age of 33 years. PSAE developed mostly on cervical and cervicothoracic levels. The median length measured 3 segments. Half of PSAE were intramedullary. Pain was the most common symptom. The median duration of symptoms was 6 months. Neurological statuses were improved in 76% following treatments, whereas clinical tumor progression occurred in 41.7%. The estimated median progression-free survival was 132 months, and the estimated median survival was 192 months. The median Ki-67 index was 15%. Patients aged less than or equal to 25 experienced worse neurological statuses and more repeated progression. Age less than or equal to 25 (HR 10.312, 95%CI 1.535-69.260, p=0.016), gross total resection (HR 0.116, 95%CI 0.020-0.688, p=0.018), and radiotherapy (HR 0.084, 95%CI 0.009-0.804, p=0.032) are three prognostic factors for tumor progression.ConclusionTumor progression remains a big concern in the clinical course of PSAE. Being aged above 25, undergoing GTR, and accepting adjuvant radiotherapy put patients at lower risk for tumor progression. Younger patients might have worse neurological statuses compared with those aged over 25.

IntroductionPatients with hematological malignancies (HMs), like chronic lymphocytic leukemia (CLL), multiple myeloma (MM), and non-Hodgkin lymphoma (NHL), have a high risk of secondary immunodeficiency (SID), SID-related infections, and mortality. Here, we report the results of a systematic literature review on the potential association of various cancer regimens with infection rates, neutropenia, lymphocytopenia, or hypogammaglobulinemia, indicative of SID.MethodsA systematic literature search was performed in 03/2022 using PubMed to search for clinical trials that mentioned in the title and/or abstract selected cancer (CLL, MM, or NHL) treatments covering 12 classes of drugs, including B-lineage monoclonal antibodies, CAR T therapies, proteasome inhibitors, kinase inhibitors, immunomodulators, antimetabolites, anti-tumor antibiotics, alkylating agents, Bcl-2 antagonists, histone deacetylase inhibitors, vinca alkaloids, and selective inhibitors of nuclear export. To be included, a publication had to report at least one of the following: percentages of patients with any grade and/or grade ≥3 infections, any grade and/or grade ≥3 neutropenia, or hypogammaglobulinemia. From the relevant publications, the percentages of patients with lymphocytopenia and specific types of infection (fungal, viral, bacterial, respiratory [upper or lower respiratory tract], bronchitis, pneumonia, urinary tract infection, skin, gastrointestinal, and sepsis) were collected.ResultsOf 89 relevant studies, 17, 38, and 34 included patients with CLL, MM, and NHL, respectively. In CLL, MM, and NHL, any grade infections were seen in 51.3%, 35.9% and 31.1% of patients, and any grade neutropenia in 36.3%, 36.4%, and 35.4% of patients, respectively. The highest proportion of patients with grade ≥3 infections across classes of drugs were: 41.0% in patients with MM treated with a B-lineage monoclonal antibody combination; and 29.9% and 38.0% of patients with CLL and NHL treated with a kinase inhibitor combination, respectively. In the limited studies, the mean percentage of patients with lymphocytopenia was 1.9%, 11.9%, and 38.6% in CLL, MM, and NHL, respectively. Two studies reported the proportion of patients with hypogammaglobulinemia: 0–15.3% in CLL and 5.9% in NHL (no studies reported hypogammaglobulinemia in MM).ConclusionThis review highlights cancer treatments contributing to infections and neutropenia, potentially related to SID, and shows underreporting of hypogammaglobulinemia and lymphocytopenia before and during HM therapies.

BackgroundMelanoma is a common and aggressive cutaneous malignancy characterized by poor prognosis and a high fatality rate. Recently, due to the application of Immune–checkpoint inhibitors (ICI) in melanoma treatment, melanoma patients’ prognosis has been tremendously improved. However, the treatment effect varies quite differently from patient to patient. In this study, we aim to construct and validate a Cuproptosis-related risk model to improve outcome prediction of ICIs in melanoma and divide patients into subtypes with different Cuproptosis-related genes.MethodsHere, according to differentially expressed genes from four melanoma datasets in GEO (Gene Expression Omnibus), and one in TCGA (The Cancer Genome Atlas) database, a novel signature was developed through LASSO and Cox regression analysis. We used 781 melanoma samples to examine the molecular subtypes associated with Cuproptosis-related genes and studied the related gene mutation and TME cell infiltration. Patients with melanoma can be divided into at least three subtypes based on gene expression profile. Survival pan-cancer analysis was also conducted for melanoma patients.ResultsThe Cuproptosis risk score can predict tumor immunity, subtype, survival, and drug sensitivity for melanoma. And Cuproptosis-associated subtypes can help predict therapeutic outcomes.ConclusionCuproptosis risk score is a promising potential biomarker in cancer diagnosis, molecular subtypes determination, TME cell infiltration characteristics, and therapy response prediction in melanoma patients.
