Human Papillomavirus Infection and Cytological Atypia in Female Allogeneic Hematopoietic Stem Cell Transplantation Recipients.

Background: Female recipients of allogeneic hematopoietic stem cell transplantation are at high risk of developing human papillomavirus (HPV)-associated lesions and (pre)cancer. We describe the results of a cervical cancer screening program in these women.

Methods: From 2010 to 2022, 70 female recipients of allogeneic hematopoietic stem cell transplantation in our institution entered a standardized protocol of gynecological evaluation.

A multilevel framework for recruitment and retention in implementation trials: An illustrative example.

Background: Implementation and hybrid effectiveness-implementation trials aspire to speed the translation of science into practice by generating crucial evidence for improving the uptake of effective health interventions. By design, they pose unique recruitment and retention challenges due to their aims, units of analysis, and sampling plans, which typically require many clinical sites (i.e.

Health impacts of asphalt emissions: Examining neurological risks and the need for long-term exposure mitigation.

Asphalt, widely used in infrastructure, emits complex chemical mixtures throughout its service life, posing significant risks to human health and the environment. This expanded understanding extends the concern from a construction-related hazard to a broader public health issue, especially affecting vulnerable populations like children who play on blacktop surfaces. Despite increased awareness, the specific mechanisms behind asphalt emissions, their impact on asphalt deterioration, and their effects on the human nervous system remain poorly understood.

A strong priority effect in the assembly of a specialized insect-microbe symbiosis.

Unlabelled: Specialized host-microbe symbioses are ecological communities, whose composition is shaped by various processes. Microbial community assembly in these symbioses is determined in part by interactions between taxa that colonize ecological niches available within habitat patches. The outcomes of these interactions, and by extension the trajectory of community assembly, can display priority effects-dependency on the order in which taxa first occupy these niches.

The dynamics of Staphylococcal infection and their treatment with antibiotics and bacteriophage in the model system.

Critical to our understanding of infections and their treatment is the role the innate immune system plays in controlling bacterial pathogens. Nevertheless, many in vivo systems are made or modified such that they do not have an innate immune response. Use of these systems denies the opportunity to examine the synergy between the immune system and antimicrobial agents.

Maximum likelihood estimators for colony-forming units.

Measuring the abundance of microbes in a sample is a common procedure with a long history, but best practices are not well-conserved across microbiological fields. Serial dilution methods are commonly used to dilute bacterial cultures to produce countable numbers of colonies, and from these counts, to infer bacterial concentrations measured in colony-forming units (CFUs). The most common methods to generate data for CFU point estimates involve plating bacteria on (or in) a solid growth medium and counting their resulting colonies or counting the number of tubes at a given dilution that have growth.

Self-guided digital behavioural therapy versus active control for fibromyalgia (PROSPER-FM): a phase 3, multicentre, randomised controlled trial.

Background: International guidelines have recommended cognitive behavioural therapy, including acceptance and commitment therapy (ACT), as it offers validated benefits for managing fibromyalgia; however, it is inaccessible to most patients. We aimed to evaluate the effect of a 12-week, self-guided, smartphone-delivered digital ACT programme on fibromyalgia management.

Methods: In the PROSPER-FM randomised clinical trial conducted at 25 US community sites, adult participants aged 22-75 years with fibromyalgia were recruited and randomly assigned (1:1) to the digital ACT group or an active control group that offered daily symptom tracking and monitoring and access to health-related and fibromyalgia-related educational materials.

Evaluation of rapid antiretroviral initiation strategy in a cohort of newly diagnosed people living with HIV in Panama, 2018-2019.

Antiretroviral therapy (ART) has been adopted as a form of HIV treatment and prevention. This study assesses rapid ART initiation using clinical outcomes such as viral load (VL) and CD4+ T lymphocytes count. Over the course of one year, the progress of newly diagnosed people living with HIV who started ART early in a hospital in Panama City was followed.

Ecological drift during colonization drives within-host and between-host heterogeneity in an animal-associated symbiont.

Specialized host-microbe symbioses canonically show greater diversity than expected from simple models, both at the population level and within individual hosts. To understand how this heterogeneity arises, we utilize the squash bug, Anasa tristis, and its bacterial symbionts in the genus Caballeronia. We modulate symbiont bottleneck size and inoculum composition during colonization to demonstrate the significance of ecological drift, the noisy fluctuations in community composition due to demographic stochasticity.

A case study to engage students in the research design and ethics of high-throughput metagenomics.

Case studies present students with an opportunity to learn and apply course content through problem solving and critical thinking. Supported by the High-throughput Discovery Science & Inquiry-based Case Studies for Today's Students (HITS) Research Coordination Network, our interdisciplinary team designed, implemented, and assessed two case study modules entitled "You Are What You Eat." Collectively, the case study modules present students with an opportunity to engage in experimental research design and the ethical considerations regarding microbiome research and society.

Parallel evolution of alternate morphotypes of Chryseobacterium gleum during experimental evolution with Caenorhabditis elegans.

Microbial evolution within polymicrobial communities is a complex process. Here, we report within-species diversification within multispecies microbial communities during experimental evolution with the nematode Caenorhabditis elegans. We describe morphological diversity in the target species Chryseobacterium gleum, which developed a novel colony morphotype in a small number of replicate communities.

Improving measurement-based care implementation in youth mental health through organizational leadership and climate: a mechanistic analysis within a randomized trial.

Background: Theory and correlational research indicate organizational leadership and climate are important for successful implementation of evidence-based practices (EBPs) in healthcare settings; however, experimental evidence is lacking. We addressed this gap using data from the WISDOM (Working to Implement and Sustain Digital Outcome Measures) hybrid type III effectiveness-implementation trial. Primary outcomes from WISDOM indicated the Leadership and Organizational Change for Implementation (LOCI) strategy improved fidelity to measurement-based care (MBC) in youth mental health services.

Slipping rib syndrome in childhood. A case series.

Among the causes of chest pain, slipping rib has a low prevalence, usually with a history of trauma, and its management is controversial. Slipping rib syndrome should be included in the differential diagnosis of causes of chest pain in children. When not associated with previous trauma and cartilage deformity, it is necessary to consider an alteration in rib development, regardless of the typical traumatic etiology in adults.

Syntheses, characterization, crystal structures and applications as sensitizers in solar cells of novel heteroleptic Cu(I) complexes containing nitrile-substituted 2,2'-bipyridyl ligands.

Two novel Cu(I) tetradentate heteroleptic complexes, including nitrile-substituted bipyridines that can be anchored to semiconductor surfaces to be assembled in DSSCs, were synthesized and characterized by spectroscopic and electrochemical techniques. The crystal structures of both species were determined by X-ray diffraction. Results from DFT and TD-DFT calculations were found to be consistent with the experimental data.

Randomized Trial of an Organizational Implementation Strategy to Improve Measurement-Based Care Fidelity and Youth Outcomes in Community Mental Health.

Objective: Measurement-based care (MBC), which collects session-by-session symptom data from patients and provides clinicians with feedback on treatment response, is a highly generalizable evidence-based practice with significant potential to improve the outcomes of mental health treatment in youth when implemented with fidelity; however, it is rarely used in community settings. This study tested whether an implementation strategy targeting organizational leadership and organizational implementation climate could improve MBC fidelity and clinical outcomes for youth in outpatient mental health clinics.

Method: In a cluster randomized trial, 21 clinics were assigned to the Leadership and Organizational Change for Implementation strategy plus training and technical assistance in MBC (k = 11, n = 117) or training and technical assistance only (k = 10, n = 117).

Cutaneous Malignant Melanoma in Chile: Differences in Tumor Thickness and Overall Survival Between Patients From Public and Private Health Care Centers.

Introduction: A low socioeconomic status (SES) is associated with lower survival rates in cutaneous malignant melanoma (CMM). In South America, there are few studies that analyze CMM data according to SES.

Objectives: To determine the differences in microstaging and overall survival in CMM between public and private health care centers.

The mobile vaccine equity enhancement program-a model program for enhancing equity in vaccine availability based at a large health care system.

The SARS CoV-2 (COVID-19) pandemic presented unprecedented challenges as communities attempted to respond to the administration of a novel vaccine that faced cold chain logistical requirements and vaccine hesitancy among many, as well as complicated phased rollout plans that changed frequently as availability of the vaccine waxed and waned. The COVID-19 pandemic also disproportionately affected communities of color and communities with barriers to accessing healthcare. In the setting of these difficulties, a program was created specifically to address inequity in vaccine administration with a focus on communities of color and linguistic diversity as well as those who had technological barriers to online sign-up processes common at mass vaccination sites.

Specialized acquisition behaviors maintain reliable environmental transmission in an insect-microbial mutualism.

Understanding how horizontally transmitted mutualisms are maintained is a major focus of symbiosis research. Unlike vertical transmission, hosts that rely on horizontal transmission produce symbiont-free offspring that must find and acquire their beneficial microbes from the environment. This transmission strategy is inherently risky since hosts may not obtain the right symbiont every generation.

Self-guided digital acceptance and commitment therapy for fibromyalgia management: results of a randomized, active-controlled, phase II pilot clinical trial.

Although empirically validated for fibromyalgia (FM), cognitive and behavioral therapies, including Acceptance and Commitment Therapy (ACT), are inaccessible to many patients. A self-guided, smartphone-based ACT program would significantly improve accessibility. The SMART-FM study assessed the feasibility of conducting a predominantly virtual clinical trial in an FM population in addition to evaluating preliminary evidence for the safety and efficacy of a digital ACT program for FM (FM-ACT).

Method versatility in RNA extraction-free PCR detection of SARS-CoV-2 in saliva samples.

Early in the pandemic, a simple, open-source, RNA extraction-free RT-qPCR protocol for SARS-CoV-2 detection in saliva was developed and made widely available. This simplified approach (SalivaDirect) requires only sample treatment with proteinase K prior to PCR testing. However, feedback from clinical laboratories highlighted a need for a flexible workflow that can be seamlessly integrated into their current health and safety requirements for the receiving and handling of potentially infectious samples.

P53 in Penile Squamous Cell Carcinoma: A Pattern-Based Immunohistochemical Framework with Molecular Correlation.

p53 immunohistochemistry (IHC) has been proposed as a surrogate for mutations in penile squamous cell carcinomas (PSCC). We aimed to evaluate the performance of a pattern-based evaluation of p53 IHC in PSCC. Human papilloma virus (HPV) DNA testing, p16 and p53 IHC, and whole exome sequencing were performed in a series of 40 PSCC.

Persistence of Pneumococcal Carriage among Older Adults in the Community despite COVID-19 Mitigation Measures.

Reported rates of invasive pneumococcal disease were markedly lower than normal during the 2020/2021 winter in the Northern Hemisphere, the first year after the start of the COVID-19 pandemic. However, little is known about rates of carriage of pneumococcus among adults during this period. Between October 2020-August 2021, couples in the Greater New Haven Area, USA, were enrolled if both individuals were aged 60 years and above and did not have any individuals under the age of 60 years living in the household.
