The human gastrointestinal tract houses trillions of microbes. The gut and various types of microorganisms, including bacteria, viruses, fungi, and archaea, form a complex ecosystem known as the gut microbiota, and the whole genome of the gut microbiota is referred to as the gut microbiome. The gut microbiota is essential for homeostasis and the overall well-being of a person and is increasingly considered an adjunct "virtual organ," with a complexity level comparable to that of the other organ systems. The gut microbiota plays an essential role in nutrition, local mucosal homeostasis, inflammation, and the mucosal immune system. An imbalanced state of the gut microbiota, known as dysbiosis, can predispose to development of various gastrointestinal malignancies through three speculated pathogenic mechanisms (a) direct cytotoxic effects with damage to the host DNA, (b) disproportionate proinflammatory signaling inducing inflammation, and (c) activation of tumorigenic pathways or suppression of tumor-suppressing pathways. Several microorganisms, including Helicobacter pylori, Epstein-Barr virus, human papillomavirus, Mycoplasma species, Escherichia coli, and Streptococcus bovis, are associated with gastrointestinal malignancies such as esophageal adenocarcinoma, gastric adenocarcinoma, gastric mucosa-associated lymphoid tissue lymphoma, colorectal adenocarcinoma, and anal squamous cell carcinoma. Imaging plays a pivotal role in diagnosis and management of microbiota-associated gastrointestinal malignancies. Appropriate use of probiotics, fecal microbiota transplantation, and overall promotion of the healthy gut are ongoing areas of research for prevention and treatment of malignancies.

Therefore, clinical breast examination by the physician and patient-detected palpable abnormalities are crucial for detecting breast cancer or recurrence. Diagnostic US is the first-line modality for evaluation of postmastectomy palpable masses, with occasional adjunct use of diagnostic mammography for confirming certain benign masses. In the setting of a negative initial imaging evaluation with continued clinical concern, diagnostic MRI may aid in improving sensitivity. Knowledge of the typical multimodality imaging appearances and locations of malignant palpable abnormalities-such as invasive carcinoma recurrence, cancer in residual breast tissue, radiation-induced sarcoma, and metastatic disease-is crucial in diagnosis and treatment of these entities. In addition, familiarity with the range of benign palpable postmastectomy processes-including fat necrosis, fat graft, seroma, granuloma, neuroma, fibrosis, and infection-may help avoid unnecessary biopsies and reassure patients. The authors review common and rare benign and malignant palpable masses in mastectomy patients, describe multimodality diagnostic imaging evaluation of each entity, review radiologic and pathologic correlation, and acquaint the radiologist with management when these findings are encountered. ©RSNA, 2021.Background Published data on the correlations of bronchoscopy findings with microbiological, radiological, and pulmonary function test results in children with noncystic fibrosis (CF) bronchiectasis (BE) are unavailable. The aims of this study were to evaluate relationships between Bronchoscopic appearance and secretion scoring, microbiological growth, radiological severity level, and pulmonary function tests in patients with non-CF BE. Methods Children with non-CF BE were identified and collected over a 6-year period. Their medical charts and radiologic and bronchoscopic notes were retrospectively reviewed. Results The study population consisted of 54 female and 49 male patients with a mean age of 11.7 ± 3.4 years. In the classification according to the bronchoscopic secretion score, Grade I was found in 2, Grade II in 4, Grade III in 9, Grade IV in 17, Grade V in 25, and Grade VI in 46 patients. When evaluated according to the Bhalla scoring system, 45 patients had mild BE, 37 had moderate BE, and 21 had severe BE. Microbial growth was detected in bronchoalveolar lavage fluid from 50 of the patients. Forced expiratory volume in 1 s (FEV1) and functional vital capacity decreased with increasing bronchoscopic secretion grade (P = 0.048 and P = 0.04), respectively. The degree of radiological severity increased in parallel with the bronchoscopic secretion score (P = 0.007). However, no relationship was detected between microbiological growth rate and radiological findings (P = 0.403). Conclusions This study showed that bronchoscopic evaluation and especially scoring of secretions correlate with severe clinical condition, decrease in pulmonary function test, worsening in radiology scores, and increase in microbiological bacterial load in patients. Flexible endoscopic bronchoscopy should be kept in mind in the initial evaluation of non-CF BE patients.Advances in cancer treatment have significantly improved childhood cancer survival, although metabolic syndrome and cardiovascular disease are common long-term complications that may occur years after treatment. Childhood cancer survivors may not receive appropriate follow-up due to lack of communication between oncologists and primary care physicians, or, from lack of awareness of possible long-term metabolic and cardiovascular complications after cancer treatment. We, therefore, reviewed current evidence on long-term effects of cancer therapy, and appropriate monitoring for long-term treatment effects in childhood cancer survivors that could lead to early detection and prompt treatment to prevent future cardiovascular events.Health care organizations are increasingly assessing patients' social needs (eg, food, utilities, transportation) using various measures and methods. Prior studies have assessed social needs at the point of care and many studies have focused on correlates of 1 specific need (eg, food). This comprehensive study examined multiple social needs and medical and pharmacy claims data. Medicaid beneficiaries in Louisiana (n = 10,275) completed a self-report assessment of 10 social needs during July 2018 to June 2019. Chronic health conditions, unique medications, and health care utilization were coded from claims data. The sample was predominantly female (72%), Black (45%) or White (32%), had a mean age of 42 years, and at least 1 social need (55%). In bivariate analyses, having greater social needs was associated with greater comorbidity across conditions, and each social need was consistently associated with mental health and substance use disorders. In multivariable logistic analyses, having ≥2 social needs was positively associated with emergency department (ED) visits (OR = 1.39, CI = 1.23 - 1.57) and negatively associated with wellness visits (OR = 0.87, CI = 0.77 - 0.98), inpatient visits (OR = 0.87, CI = 0.76 - 0.99), and 30-day rehospitalization (OR = 0.66, CI = 0.50 - 0.87). Findings highlight the greater concomitant risk of social needs, mental health, and substance use. Admission policies may reduce the impact of social needs on hospitalization. Chronic disease management programs offered by health plans may benefit from systematically assessing and addressing social needs outside point-of-care interactions to impact health outcomes and ED utilization. Behavioral health care management programs would benefit from integrating interventions for multiple social needs.Using telemedicine to improve asthma management in underserved communities has been shown to be highly effective. However, program operating costs are perceived as the main barrier to dissemination and scaling up. This study evaluated whether a novel, evidence-based School-Based Telemedicine Enhanced Asthma Management (SB-TEAM) program, designed to overcome barriers to care for families of urban school-aged children, can be financially sustainable in real-world urban school settings. Eligible children (n = 400) had physician-diagnosed asthma with persistent or poorly controlled symptoms at baseline. Total costs included the cost of implementing and running the SB-TEAM program, asthma-related health care costs, cost of caregiver lost productivity in wages related to child illness, and school absenteeism fees. Using data from the SB-TEAM study and national data on wages and equipment costs, the authors modeled low, actual, and high-cost scenarios. The actual cost of administering the SB-TEAM program averaged $344 per child. Expenses incurred by families for medical care ($982), caregiver productivity cost ($415), and school absenteeism costs ($284) in SB-TEAM were not different from the costs in the control group ($1594, $492, and $318 [P > 0.05]). The study findings remained robust under sensitivity analyses for various state- and school-specific regulations, staffing requirements, and wages. The authors concluded that the SB-TEAM program operating costs may be offset by the reduction in health care costs, caregiver lost wages, and school absenteeism associated with the program health benefit.A series of 2'-deoxy and novel 2'-O-methyl and 2'-O-(2-methoxyethyl) (2'-MOE) oligonucleotides with internucleotide methanesulfonyl (mesyl, μ) or 1-butanesulfonyl (busyl, β) phosphoramidate groups has been synthesized for evaluation as potential splice-switching oligonucleotides. Evaluation of their splice-switching activity in spinal muscular atrophy patient-derived fibroblasts revealed no significant difference in splice-switching efficacy between 2'-MOE mesyl oligonucleotide and the corresponding phosphorothioate (nusinersen). Yet, a survival study with model neonatal mice has shown the antisense 2'-MOE mesyl oligonucleotide to be inferior to nusinersen at the highest dose of 40 mg/kg. A reason for their lower activity in vivo as ascertained by cellular uptake study by fluorescent confocal microscopy in HEK293 cell line could possibly be ascribed to compromised endosomal release and/or nuclear uptake of the 2'-OMe or 2'-MOE μ- and β-oligonucleotides compared to their phosphorothioate analog.Little information has been compiled across studies about existing interventions to mitigate issues of medical financial hardship, despite growing interest in health care delivery. The purpose of this qualitative systematic scoping review was to examine content and outcomes of interventions to address medical financial hardship. PRISMA guidelines were applied to present results using PubMed, Scopus, and CINAHL, published between January 1980 and August 2020. Additional studies were identified through reference lists of selected papers. Included studies focused on mitigating medical financial hardship from out-of-pocket (OOP) health care expenses as an intervention strategy with at least 1 evaluation component. Screening 2412 articles identified 339 articles for full-text review, 12 of which met inclusion criteria. Variation was found regarding targets and outcome measurement of intervention. Primary outcomes were in the following categories financial outcomes (eg, OOP expenses), behavioral outcomes, psychosocial, health care utilization, and health status.
