Cadmium toxicity on communities of ammonia-oxidizing microorganisms.

The oxidation of ammonia to nitrite, which constitutes the initial and rate-limiting step in the nitrification process, plays a pivotal role in the transformation of ammonia within soil ecosystems. Due to its susceptibility to a range of pollutants, such as heavy metals, pesticides, and pharmaceuticals, nitrification serves as a valuable indicator in the risk assessment of chemical contaminants in soil environments. Here, we analyzed the effects of cadmium (Cd) treatment on soil potential nitrification rate (PNR), and the abundance of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacte

Safety of steroids in severe community-acquired pneumonia.

The systemic use of corticosteroids for patients with severe community-acquired pneumonia (sCAP) remains controversial in clinical practice, particularly in terms of the safety profile of these drugs. This narrative review aims to analyse the available literature data concerning the safety of short-term steroid use in the treatment of sCAP, while also highlighting potential future research directions. Several trials and meta-analyses have evaluated corticosteroid therapy as an adjuvant treatment for sCAP, yielding heterogeneous results regarding its efficacy and safety. Despite the wide variab

A Pragmatic Trial of Glucocorticoids for Community-Acquired Pneumonia.

BACKGROUND: Adjunctive glucocorticoids may reduce mortality among patients with severe community-acquired pneumonia (CAP) in well-resourced settings. Whether these drugs are beneficial in low-resource settings with limited diagnostic and treatment facilities is unclear. METHODS: In this pragmatic, open-label, randomized, controlled trial conducted in 18 public hospitals in Kenya, we assigned adult patients who had received a diagnosis of CAP and who did not have a clear indication for glucocorticoids to receive either standard care for CAP or oral low-dose glucocorticoids for 10 days in addit

Neonatal Outreach Training: Identifying Needs in the Community.

This study aimed to identify the neonatal training needs of levels I and II community health centers (CHCs).We conducted a mixed-methods study involving a questionnaire, focus groups (FG), and an audit of neonatal transport data. The questionnaire assessed the felt needs of CHC staff, FGs identified normative needs with an expert neonatal transport team, and the audit captured expressed needs using data from the Canadian neonatal transport network.A total of 158 respondents from 12 CHCs completed the questionnaire (98% completeness rate). Key findings indicated significant challenges in human

Making fertility preservation happen for the transgender community.

Transgender individuals, whose gender identity differs from their assigned sex at birth, may undergo gender-affirming hormone therapy (GAHT) and gender-affirming surgery (GAS) to alleviate gender dysphoria. These treatments often impact future reproductive potential, necessitating fertility preservation (FP) discussions. Healthcare guidelines from the American Society of Reproductive Medicine (ASRM), World Professional Association for Transgender Health (WPATH), and the Endocrine Society recommend counseling on FP options, which include oocyte, sperm, and embryo cryopreservation. Challenges re

Community Water Trihalomethanes and Chronic Kidney Disease.

IMPORTANCE: Over 90% of the US population relies on community water supplies (CWS), which generally use chlorine for disinfection. Trihalomethanes are regulated disinfection byproducts associated with bladder cancer and adverse birth outcomes. Animal studies report trihalomethanes, especially brominated compounds, may damage kidney function, but epidemiologic research is limited. OBJECTIVE: To evaluate long-term exposure to trihalomethanes in residential CWS and its association with chronic kidney disease (CKD) risk. DESIGN, SETTING, AND PARTICIPANTS: The California Teachers Study (CTS) is a

Microbiota of the Lung Tuberculoma: Paucibacillary Bacterial Community.

Caseum, the central necrotic material of tuberculous lesions, is a reservoir of drug-resistant persisting Mycobacterium tuberculosis (MTB). However, tubercle bacilli are not the only bacterial inhabitants of this necrosis. We discuss the available data on metagenomic and amplicon sequencing of 16S rRNA of caseous necrosis from surgically excised tuberculosis (TB) foci. This approach facilitated the characterization of the biodiversity and the potential biochemical pathways of these bacterial communities. We postulate that in terms of MTB content relative to satellite anaerobic lipophilic bacte

Female frogs communicate with males through blinking.

Blinking is a behavior unique to animal taxa with motile eyelids, such as most amphibians and reptiles as well as all birds and mammals1. Eyelid movement has physiological functions, such as lubricating the cornea and washing away dust, but its potential signaling functions are not well understood1,2. The use of eyeblinks as a social signal is currently thought to be restricted to some primates, especially humans and their companion animals, but has not been verified in other taxa1,3,4. Here, through field observation and experiments, we demonstrate that female concave-eared torrent frogs (Odo

Treatment of Acute Myeloid Leukemia in the Community Setting.

The treatment landscape for acute myeloid leukemia (AML) is rapidly changing. Many new agents and lower-intensity regimens have been approved and can be safely used by hematologists and oncologists in both academic and community settings. The US Food and Drug Administration (FDA) held a virtual symposium on AML treatment in the community in November 2022. Several members of the FDA, along with practicing hematologists and oncologists in both academic and community settings, participated in the symposium. The goal of the symposium was to discuss challenges and opportunities in the treatment of

ScyNet: Visualizing interactions in community metabolic models.

MOTIVATION: Genome-scale community metabolic models are used to gain mechanistic insights into interactions between community members. However, existing tools for visualizing metabolic models only cater to the needs of single organism models. RESULTS: ScyNet is a Cytoscape app for visualizing community metabolic models, generating networks with reduced complexity by focusing on interactions between community members. ScyNet can incorporate the state of a metabolic model via fluxes or flux ranges, which is shown in a previously published simplified cystic fibrosis airway community model. AVAI

New Guidelines for Severe Community-acquired Pneumonia.

In 2023, the new European guidelines on severe community-acquired pneumonia, providing clinical practice recommendations for the management of this life-threatening infection, characterized by a high burden of mortality, morbidity, and costs for the society. This review article aims to summarize the principal evidence related to eight different questions covered in the guidelines, by also highlighting the future perspectives for research activity.

Impact of the improvement in the etiological diagnosis of community pneumonia.

BACKGROUND AND OBJECTIVE: Etiological diagnosis of community-acquired pneumonia (CAP) is only reached in 30-40% of cases, which frequently requires keeping empirical antibiotic regimens. The new nucleic acid amplification techniques (NAAT) in respiratory samples raise the possibility of improving this clinical practice. Our objective was to analyze TAANs contribution estimating both their costs and benefits. PATIENTS AND METHODS: The admitted CAPs were analyzed, in which, if the conventional diagnostic tests were negative, a NAAT was performed. If positive results was made, we assessed if ant

Severe Community-Acquired Pneumonia in Immunocompromised Patients.

Due to higher survival rates with good quality of life, related to new treatments in the fields of oncology, hematology, and transplantation, the number of immunocompromised patients is increasing. But these patients are at high risk of intensive care unit admission because of numerous complications. Acute respiratory failure due to severe community-acquired pneumonia is one of the leading causes of admission. In this setting, the need for invasive mechanical ventilation is up to 60%, associated with a high hospital mortality rate of around 40 to 50%. A wide range of pathogens according to the

The historical demography of the Martha's Vineyard signing community.

The deaf population of Martha's Vineyard has fascinated scholars for more than a century since Alexander Graham Bell's research on the frequent occurrence of deafness there and since Groce's book on the island's signing community (Groce, N. E. (1985). Everyone here spoke sign language: Hereditary deafness on Martha's Vineyard. Cambridge, MA: Harvard University Press.). In Groce's work, and in that of subsequent scholars, the Vineyard signing community has often been portrayed as remote and outlying, having developed independently of mainland signing communities for roughly 133 years until 1825

Drug treatment courts and community-level crime.

Research has recognized Adult Drug Treatment Courts (DTCs) as benefitting participants, with a wide body of research demonstrating lower levels of recidivism and drug use. A budding community-level body of research, however, has returned mixed results, some studies showing increases in arrests and crime relative to DTC initiation. Since DTCs cover over three-fourths of the US population, results showing such unintended consequences must be validated and rectified if held. This study estimated effects for DTCs for community-level crime effects from 1990 to 2018 using a stacked event study ident

The Well-Being of Older Offenders on Release in the Community.

In Canada and internationally the number of older offenders on parole and living in the community is increasing rapidly. Older offenders in the community are a vulnerable population at high risk for lack of well-being. Semi-structured interviews were conducted with N = 64 offenders aged 50 years and older on conditional release from custody in Canada, including long-term, recidivist, and first-time older offenders. Compared to their non-offender counterparts, older offenders in the community experience many of the same problems of aging and well-being, but are at greater risk for mental health

A Community Initiative to Help Children Who Are Homeless.

Children experiencing homelessness (CEH) have several health-related needs. It is necessary to address barriers posed by homelessness to improve health outcomes. Our objectives were to (1) conduct a health-related needs assessment and (2) determine acceptability/feasibility of the community-based initiative designed to identify and address health-related needs for CEH. The initiative involved a mobile care center, a health-focused education series for CEH, and resource provision, which included establishing connections with a stable source of health care. The needs assessment included standard
