The exposome, reflecting the range of environmental exposures individuals encounter throughout their life, can influence a variety of health outcomes and can play a role in how the environment impacts our genes. Telomeres, genetic structures regulating cell growth and senescence, are one pathway through which the exposome may impact health. Greenspace exposure, representing the amount of green areas in one's neighborhood, is one component of the exposome and has been associated with multiple health benefits. To investigate the potential link between greenspace exposure and telomere length, we analyzed data from the 1999-2001 National Health and Nutrition Examination Survey (NHANES) sample. Our study examined individual, risk, and contextual factors. We found that greater greenspace exposure in one's neighborhood was associated with longer telomere lengths when considering individual and risk factors, suggesting a positive effect of living in greener neighborhoods. However, this relationship became non-significant when contextual factors, such as air pollution and deprivation, were included in the analysis. These findings highlight a complex relationship between greenspace and telomere length, warranting further research to explore contextual factors in detail., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Stenotrophomonas maltophilia is an opportunistic infection commonly encountered in various systems of the human body and has been noted to be a rare cause of osteomyelitis. This report examines a rare case of osteomyelitis of the foot caused by S. maltophilia from a poorly managed foot wound and highlights the successful treatment of this condition with trimethoprim-sulfamethoxazole monotherapy., Competing Interests: The author has no conflict of interest to declare., (© 2023 Published by Elsevier Ltd.)

Thrombotic thrombocytopenic purpura (TTP) is a rare variant of thrombotic microangiopathy. We report a case of TTP in a Nigerian chronic kidney disease (CKD) patient who was previously on clopidogrel. The features of TTP resolved soon after clopidogrel was withdrawn. Clopidogrel is a cardio-protective anti-platelet drug used in CKD patients at risk of dyspepsia. However, its potential to cause TTP should be recognized and considered in acute kidney injury (AKI) patients previously on clopidogrel., (© 2023 Ndulue CN et al.)

Background: Black and Hispanic individuals experience poorer outcomes related to coronavirus disease (COVID-19), yet have alarmingly lower uptake of the COVID-19 vaccine compared to non-Hispanic White individuals., Objective: To explore the perceptions of barriers and facilitators of COVID-19 vaccine acceptance among Black and Hispanic adults in the New York., Methods: A qualitative study consisting of one-on-one semistructured interviews with Black and/ or Hispanic adults in New York state was conducted. Participants were recruited from local businesses, community-based social service agencies and Black and Hispanic churches and a college. All data were collected between February and March 2021. Transcripts were analyzed using qualitative thematic analysis., Results: A total of 50 individuals (32 [64%] women; mean [SD] age, 42.04 [15.99] years) participated. The majority of participants identified as Black (n = 34, 68%), 9 (18%) identified as Hispanic, 3 (6%) as Black and Hispanic, and 4 (8%) as White and Hispanic. Twenty-two participants (44%) had high-school level education or less. Mistrust emerged as a central barrier to COVID-19 vaccine acceptance. Facilitators of effective COVID-19 vaccine messages include (1) key informants: like me, (2) personalized community outreach, (3) present the facts, and (4) communicate across multiple media platforms., Conclusions: This qualitative study found that among Black and Hispanic participants, receipt of reliable vaccine related information, social networks, seeing people like themselves receive the vaccination, and trusted doctors are key drivers of vaccine acceptance., (Copyright © 2021 Association for Professionals in Infection Control and Epidemiology, Inc.

The clinical management of severely ill patients with COVID-19-related acute respiratory distress syndrome (ARDS) presents significant challenges. Many COVID-19 patients with ARDS also present with laboratory findings significant for derangement in coagulation function. In this report, we describe acute pulmonary embolism in three patients with COVID-19. We assessed the role of D-dimer assay and anticoagulation treatment in these patients. The aim of this case report is to increase awareness about the use of D-dimer in addition to patient's clinical status for making treatment decision in COVID-19 patients., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Nonso Osakwe and Douglas Hart.)

This report describes a case of Bacillus cereus bacteremia in a COVID-19 patient with prior inhalational steroid use and inpatient steroid treatment for COVID-19 pulmonary symptoms. The case herein is intended to illustrate an uncommon presentation of B. cereus bacteremia and highlight the increased likelihood for the occurrence of this bacteremia in patients with COVID-19 and concomitant steroid use., (© 2020 Published by Elsevier Ltd.)

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare condition associated with viral infections including HIV. Cases have been reported mainly in advanced HIV/AIDS. This is a rare case that reports HLH associated with human herpes virus-8 (HHV-8) associated multicentric Castleman disease in a stable HIV patient., Case Presentation: A 70-year-old Asian male patient with history of stable HIV on medications with CD 4 cell count above 200 presented with cough and fever and was initially treated for pneumonia as an outpatient. Persisting symptoms prompted presentation to the hospital. The patient was found to have anemia which persisted despite repeated transfusion of packed red cells. A bone marrow biopsy to investigate anemia revealed hemophagocytosis. A CT scan revealed multiple enlarged lymph nodes and hepatosplenomegaly. An excisional lymph node biopsy revealed HHV-8 associated multicentric Castleman disease. The patient deteriorated despite initiation of treatment., Conclusion: HLH can occur at any stage of HIV, rapid diagnosis to identify possible underlying reactive infectious etiology and prompt initiation of treatment is crucial to survival.

Legionnaire's disease (LD) is a non-zoonotic atypical community acquired pneumonia (CAP) with several characteristic extra-pulmonary findings. Pending diagnostic test results, selected characteristic findings when considered together are the basis of clinical syndromic diagnosis and the basis of empiric antimicrobial therapy. Of the extra-pulmonary manifestation of LD, neurologic findings are among the most common, e.g., headache, mental confusion. In LD, encephalitis is rare as are myoclonus and seizures. This is a most interesting case of LD that presented with encephalitis, myoclonus and seizures. Pulmonary infiltrates developed early after admission. LD was suspected on the basis of otherwise unexplained characteristic findings, e.g., hypophosphatemia, elevated serum transaminases, microscopic hematuria, elevated ferritin, and empiric doxycycline therapy was started. The diagnosis of LD was further supported by prominent and persistent myoclonus and seizures, rare but characteristic neurologic findings in LD. On week 12 of hospitalization, he finally seroconverted with negative urinary antigen tests indicating his LD was due to a non- L. pneumophilia (serotype 01) strain. On doxycycline, he made a slow but complete recovery. We believe this is the first reported case of LD presenting with encephalitis, myoclonus, and seizures successfully treated with doxycycline.

Background: Patients who present with early stage non-small cell lung cancer and are poor candidates for lobar resection may be offered sublobar resection (commonly wedge) or stereotactic body radiotherapy (SBRT). However, comparing the relative effectiveness of these techniques is difficult because of differences in patient selection. We performed a propensity-matched analysis to compare the different treatment modalities. We compared the overall recurrence, overall survival, disease-free survival, and recurrence-free survival between treatment groups., Methods: A prospectively collected database was reviewed for patients who underwent a wedge resection, a wedge plus brachytherapy, or SBRT for clinical stage IA non-small cell lung cancer from 2001 to 2012. Patients who underwent SBRT were further assessed to confirm operability. Univariate and Cox regression multivariate analysis were performed for predictors of a composite end point of recurrence and mortality., Results: There were 164 patients identified, from which 99 were matched by age, sex, and histology. There were 61 women (62%) and 38 men (38%) with a median age of 73 years. Thirty-eight patients underwent a wedge resection only, 38 patients underwent a wedge with brachytherapy, and 23 patients had SBRT. Median follow-up was 35 months. Overall recurrence (local and distant) was significantly higher after SBRT (wedge, 9%; SBRT, 30%; p = 0.016). Although recurrence-free 3 -year survival was significantly better after wedge resection (88% versus 72%; p = 0.001), there was no difference between the two groups in disease-free 3-year survival (77% versus 59%; p = 0.066). Multivariate regression analysis identified male sex and SBRT as significant predictors for mortality and recurrence., Conclusions: Patients with clinical stage IA non-small cell lung cancer treated by SBRT appear to have higher overall disease recurrence than those treated by wedge resection. However, there was no significant difference in disease-free survival. A randomized trial is needed to define the role of SBRT in the potentially operable patient., (Copyright © 2014 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)
