RESUMO

African American women suffer under the burden of cervical cancer as they are first in mortality, diagnosed at later stages, and have a survivorship rate that is lower than the national average. The aim of our review is to evaluate the effectiveness of cervical cancer screening and prevention interventions for African American women living in the United States and to assess their commitment to health equity. A literature search was conducted using PubMed, Embase, CINAHL, and Scopus using MeSH terms related to cervical cancer, human papillomavirus (HPV), screening and prevention, and African Americans. This resulted in 1970 articles. Studies were included if they promoted cervical screening or prevention, sampled African American women aged 18 and over, and evaluated interventions. Among the 23 articles that met inclusion criteria, there were a wide variety of intervention strategies, that is, community health workers, patient navigation, patient reminders, self-sampling collection, and HPV vaccination. Health education interventions, when coupled with patient navigation or community health workers, were effective in promoting screening participation (odds ratio: 2.43, 95% confidence interval: 1.47-4.02). There were mixed results regarding the incorporation of health equity principles. This review supports the importance of incorporating health equity principles and community based methods in screening and prevention interventions. Future research and practice should incorporate African American women's perspectives in intervention development and implementation.

RESUMO

OBJECTIVE: The use of transesophageal echocardiography (TEE) by certified registered nurse anesthetists (CRNAs) during noncardiac surgery is relatively uncommon despite its unique potential to diagnose causes of hemodynamic instability. To address this problem, educational endeavors designed to provide practical TEE skills to CRNAs are needed. The aim of the current study was to evaluate the feasibility, acceptability, efficacy, and utility of a 2-day focused TEE workshop in nurse anesthesia education that employed a protocol involving a limited number of views and used goal-directed, qualitative assessments of critical physiologic parameters. METHODS: This was a prospective, observational study involving 14 second-year nurse anesthesia students. The cohort was evaluated following completion of this workshop by simulator-based testing involving hypothetical clinical scenarios, and this test data was analyzed according to the percent successful acquisition and interpretation of TEE views to determine immediate objective teaching efficacy. The acceptability, perceived efficacy, and perceived utility of the workshop were assessed by online survey, and survey responses were qualitative and quantitative in nature. RESULTS: Participants acquired appropriate TEE views associated with clinical scenarios 99% of the time and correctly interpreted the pathology in those views 93% of the time. Participants uniformly perceived significant educational value in this workshop and intend to incorporate TEE in their future clinical practice. CONCLUSIONS: A 2-day workshop to teach focused TEE to nurse anesthesia trainees directed by a streamlined protocol is feasible, acceptable, and perceived as useful by participants, and provides practical experience and entry-level competency in this point-of-care ultrasound modality.

RESUMO

Rural women face an increased risk of cervical cancer diagnosis in comparison to women living in metropolitan areas. This review synthesized and critically evaluated cervical cancer screening interventions that target women living in rural communities in the USA. EBSCO, JSTOR, Medline, PsychINFO, Psychology and Behavioral Sciences Collection, PubMed, and Cochrane Library were searched using keywords related to cervical cancer screening, rural communities, and prevention interventions. Study eligibility included randomized controlled trials or quasi-experimental designs, a psychosocial or educational intervention targeting cervical cancer prevention, and implementation in a rural setting. Eleven articles met criteria for the systematic review and 6 of those included information sufficient for meta-analysis. Cochrane guidelines, CONSORT-Equity 2017, and PROGRESS-Plus were used to assess included studies. The systematic review encompassed 9720 participants who were involved in a variety of intervention types: social media campaigns, faith-based, and patient navigation with lay health advisors. None of the studies met all criteria for the health equity assessment. The meta-analysis found that women in the intervention groups were more likely to participate in cervical cancer screening than women in control groups (OR: 2.43, 95% CI: 1.49 to 3.97). The type of intervention mattered in increasing cervical cancer screening participation for women living in rural communities. Educational interventions in combination with patient navigation saw the most success in promoting cervical cancer screening. Further, health inequities focus is lacking robust consideration. Our results highlight a continued need to develop multicomponent interventions with a health equity focus to address barriers to screening and prevention.

RESUMO

Optimization of retinal prostheses requires preclinical animal models that mimic features of human retinal disease, have appropriate eye sizes to accommodate implantable arrays, and provide options for unilateral degeneration so as to enable a contralateral, within-animal control eye. In absence of a suitable non-human primate model and shortcomings of our previous feline model generated through intravitreal injections of Adenosine Triphosphate (ATP), we aimed in the present study to develop an ATP induced degeneration model in the rabbit. Six normally sighted Dutch rabbits were monocularly blinded with this technique. Subsequent retinal degeneration was assessed with optical coherence tomography, electroretinography, and histological assays. Overall, there was a 42% and 26% reduction in a-wave and oscillatory potential amplitudes in the electroretinograms respectively, along with a global decrease in retinal thickness, with increased variability. Qualitative inspection also revealed that there were variable levels of retinal degeneration and remodeling both within and between treated eyes, mimicking the disease heterogeneity observed in retinitis pigmentosa. These findings confirm that ATP can be utilized to unilaterally induce blinding in rabbits and, potentially present an ideal model for future cortical recording experiments aimed at optimizing vision restoration strategies.Clinical Relevance- A rapid, unilaterally induced model of retinal degeneration in an animal with low binocular overlap and large eyes will allow for clinically valid recordings of downstream cortical activity following retinal stimulation. Such a model would be highly beneficial for the optimization of clinically appropriate vision restoration approaches.

RESUMO

BACKGROUND: Latent safety threats (LSTs-characteristics of design, processes, or physical environment in health care compromising patient safety) are commonly revealed during simulation-based training. Methods of collecting, analyzing, and classifying LSTs are underdeveloped and not standardized. Building on a large simulation program in one organization, the authors aimed to collect LSTs systematically and develop a taxonomy to classify them. METHODS: The authors modified the Press Ganey Healthcare Performance Improvement Failure Modes Taxonomy (HPI-FMT), a standardized framework for safety event classification in health care, and used three categories: System, Individual, and Medications. The subcategories were revised to reflect simulation LST content and promote consistent data entry into a spreadsheet. Data visualization software was used to analyze LST data and generate dashboards, graphs, and executive summaries to share across the system that depicted data for individual hospitals and outpatient areas and allowed grouping, comparisons, and trending. RESULTS: Over a year, the researchers identified 1,318 LSTs in 232 simulations across the organization-a rate of 5.7 LSTs/simulation. The top three LST subcategories were Environment/supplies/equipment (System category); Process/structure (System category); and Knowledge or unformed skill/habit (Individual category). Other important LSTs were Missing/malfunctioning supplies/equipment; Unclear or ineffective process or no process; and Unfamiliarity with supplies/equipment. When a repetitive pattern of LSTs was observed (for example, improper dantrolene use during malignant hyperthermia simulations), targeted process improvement or training was implemented. CONCLUSION: The authors developed, implemented, and refined a systematic method of collecting, analyzing, displaying LSTs, and recommending targeted process improvements or training when LST trends were noted.

RESUMO

INTRODUCTION: Supervised machine learning approaches are increasingly used to analyze clinical data, including in geriatric oncology. This study presents a machine learning approach to understand falls in a cohort of older adults with advanced cancer starting chemotherapy, including fall prediction and identification of contributing factors. MATERIALS AND METHODS: This secondary analysis of prospectively collected data from the GAP 70+ Trial (NCT02054741; PI: Mohile) enrolled patients aged ≥70 with advanced cancer and ≥ 1 geriatric assessment domain impairment who planned to start a new cancer treatment regimen. Of ≥2000 baseline variables ("features") collected, 73 were selected based on clinical judgment. Machine learning models to predict falls at three months were developed, optimized, and tested using data from 522 patients. A custom data preprocessing pipeline was implemented to prepare data for analysis. Both undersampling and oversampling techniques were applied to balance the outcome measure. Ensemble feature selection was applied to identify and select the most relevant features. Four models (logistic regression [LR], k-nearest neighbor [kNN], random forest [RF], and MultiLayer Perceptron [MLP]) were trained and subsequently tested on a holdout set. Receiver operating characteristic (ROC) curves were generated and area under the curve (AUC) was calculated for each model. SHapley Additive exPlanations (SHAP) values were utilized to further understand individual feature contributions to observed predictions. RESULTS: Based on the ensemble feature selection algorithm, the top eight features were selected for inclusion in the final models. Selected features aligned with clinical intuition and prior literature. The LR, kNN, and RF models performed equivalently well in predicting falls in the test set, with AUC values 0.66-0.67, and the MLP model showed AUC 0.75. Ensemble feature selection resulted in improved AUC values compared to using LASSO alone. SHAP values, a model-agnostic technique, revealed logical associations between selected features and model predictions. DISCUSSION: Machine learning techniques can augment hypothesis-driven research, including in older adults for whom randomized trial data are limited. Interpretable machine learning is particularly important, as understanding which features impact predictions is a critical aspect of decision-making and intervention. Clinicians should understand the philosophy, strengths, and limitations of a machine learning approach applied to patient data.

RESUMO

The minimally invasive repair of pectus excavatum (MIRPE), or Nuss procedure, is regarded as the gold standard technique for the treatment of symptomatic pectus excavatum. Minimally invasive repair of pectus excavatum is regarded as a low-risk operation with a reported life-threatening complication rate estimated at around 0.1%. Presented are three cases of right internal mammary artery injury (RIMA) after MIRPE resulting in massive hemorrhage in both the acute and chronic postoperative setting and subsequent management strategies. Exploratory thoracoscopy and angioembolization were utilized which achieved prompt hemostasis and allowed for complete patient recovery.

RESUMO

BACKGROUND: The COVID-19 pandemic has caused major disruption to health systems, with allogeneic haemopoietic cell transplant (alloHCT) services a particularly vulnerable area. Ongoing provision of alloHCT has required dynamic responses at national and local levels. In Australia and New Zealand (ANZ), a high reliance on unrelated donors from overseas registries has posed an additional challenge. AIMS: To describe the impact of COVID-19 on alloHCT services in ANZ in the first year of the pandemic. METHODS: Data from the national alloHCT patient and unrelated donor registries were extracted for a 2-year time frame. Comparisons were made between a pre-pandemic period of 1 March 2019 to 29 February 2020 and the corresponding dates during the pandemic, 1 March 2020 to 28 February 2021. RESULTS: There was a 13% decrease in the number of allogeneic transplants, a reversal of steady increases in previous years, with the largest decrease in unrelated donor transplants. Local donors supplied a greater proportion of unrelated stem cell products. With a switch to universal cryopreservation, the time from request of a product to infusion increased by a median of 25.5 days for overseas products and 14 days for local products. There was a significant increase in the number of products collected but not used. CONCLUSIONS: A strong public health response and coordinated transplant community activities allowed for safe provision of alloHCT in ANZ; however, our data suggest that the timely delivery of allogeneic transplants was affected by the COVID-19 pandemic. Continued dedicated efforts are required to minimise further impacts.

RESUMO

INTRODUCTION: Surgical correction of pectus excavatum by Nuss procedure, commonly referred to as minimally invasive repair of pectus excavatum (MIRPE), often results in significant postoperative pain. This study investigated whether adding intraoperative methadone would reduce the postoperative opioid requirement during admission for patients undergoing MIRPE. METHODS: A retrospective cohort chart review was conducted for 40 MIRPE patients between 2018 and 2020. Patients were stratified into 2 groups: those who received multimodal anesthesia (MM, n = 20) and those who received multimodal anesthesia with the addition of intraoperative methadone (MM + M, n = 20). Data collected included total opioid consumption during hospital stay (morphine milligram equivalents [MMEs]), hospital length of stay (LOS), pain scores, time to ambulation, and time to tolerating solid food. RESULTS: Addition of intraoperative methadone for patients undergoing MIRPE significantly reduced postoperative opioid requirements (MME/kg) during admission (P = .007). On average, patients in the MM group received 1.61 ± .55 MME/kg while patients in the MM + M group received 1.16 ± .44 MME/kg. Hospital opioid (non-methadone) total was also significantly reduced between the MM (1.87 ± .54) and MM + M group (1.37 ± .46), P = .003. There was no significant difference in hospital opioid total MME/kg administered between the groups. There were no significant differences observed in hospital LOS, pain scores, time to ambulation, or time to toleration of solid food. DISCUSSION: Incorporating intraoperative methadone for patients undergoing MIRPE reduced postoperative opioid requirements and hospital opioid (non-methadone) totals without a significant change in pain scores. Patients undergoing the Nuss procedure may benefit from the administration of intraoperative methadone.

RESUMO

BACKGROUND: Obesity has played a central role in heightened coronavirus disease 2019 (COVID-19) risk and vaccine response. COVID-19 vaccine intention among those with a history of severe obesity, specifically those who have undergone bariatric surgery, has not been described. This study aims to examine early COVID-19 vaccine intention among mothers with a history of severe obesity who underwent bariatric surgery. METHODS: Sixty-four mothers (Mage = 39.3 years) who underwent bariatric surgery (Mtime since surgery = 19.6 months) completed surveys online (November 2020-February 2021). Information obtained included their COVID-19 vaccine intention (vaccine ready, undecided, vaccine opposed). Analyses examined group differences in demographics, body mass index (BMI = kg/m2), knowledge of obesity-related COVID-19 risk, flu vaccination history, general beliefs about vaccine safety/effectiveness, and factors increasing confidence/motivation to obtain a COVID-19 vaccine. RESULTS: Thirty-six (56.3%) mothers had severe obesity (≥ Class II [BMI = ≥ 35 kg/m2]). The majority were vaccine hesitant (undecided [n = 28; 43.8%]; vaccine opposed [n = 15; 23.4%]). Compared to the vaccine-ready group, vaccine-hesitant groups were younger (p < .05). For the vaccine opposed, recent flu vaccination rates (p = .012) and general belief that vaccines are safe (p = .028) were lower than expected. Among hesitant participants, no reported side effects and the health of self and others were endorsed as top factors increasing vaccine confidence and motivation respectively. CONCLUSIONS: While preliminary, the prominence of early vaccine hesitancy in this sample of mothers who have undergone bariatric surgery, with most persisting with severe obesity, indicates a subgroup at high risk. Factors to address through targeted messaging and intervention were identified.

RESUMO

Here we describe the design and implementation of a novel data management platform for an academic cancer center which meets the needs of multiple stakeholders. A small, cross-functional technical team identified key challenges to creating a broad data management and access software solution: lowering the technical skill floor, reducing cost, enhancing user autonomy, optimizing data governance, and reimagining technical team structures in academia. The Hyperion data management platform was designed to meet these challenges in addition to usual considerations of data quality, security, access, stability, and scalability. Implemented between May 2019 and December 2020 at the Wilmot Cancer Institute, Hyperion includes a sophisticated custom validation and interface engine to process data from multiple sources, storing it in a database. Graphical user interfaces and custom wizards permit users to directly interact with data across operational, clinical, research, and administrative contexts. The use of multi-threaded processing, open-source programming languages, and automated system tasks (normally requiring technical expertise) minimizes costs. An integrated ticketing system and active stakeholder committee support data governance and project management. A co-directed, cross-functional team with flattened hierarchy and integration of industry software management practices enhances problem solving and responsiveness to user needs. Access to validated, organized, and current data is critical to the functioning of multiple domains in medicine. Although there are downsides to developing in-house customized software, we describe a successful implementation of custom data management software in an academic cancer center.

RESUMO

Ubiquitin carboxy-terminal hydrolase L1 (UCHL1), a deubiquitinating enzyme (DUB), is a potential drug target in various cancers, and liver and lung fibrosis. However, bona fide functions and substrates of UCHL1 remain poorly understood. Herein, we report the characterization of UCHL1 covalent inhibitor MT16-001 based on a thiazole cyanopyrrolidine scaffold. In combination with chemical proteomics, a closely related activity-based probe (MT16-205) was used to generate a comprehensive quantitative profile for on- and off-targets at endogenous cellular abundance. Both compounds are selective for UCHL1 over other DUBs in intact cells but also engage a range of other targets with good selectivity over the wider proteome, including aldehyde dehydrogenases, redox-sensitive Parkinson's disease related protein PARK7, and glutamine amidotransferase. Taken together, these results underline the importance of robust profiling of activity-based probes as chemical tools and highlight the cyanopyrrolidine warhead as a versatile platform for liganding diverse classes of protein with reactive cysteine residues which can be used for further inhibitor screening, and as a starting point for inhibitor development.

RESUMO

Dietary patterns associated with risk for colorectal cancer (CRC) may contribute to continuing health disparities in Latinx populations. Latinx from low-income communities, aged 25-65, were randomized to a 12-week storytelling-based intervention (ST) (n = 300) or didactic learning (DL)(n = 285) classes on cancer screening and dietary changes related to CRC risk facilitated by Latinx lay health workers (promotora/es de salud). Dietary intake was assessed pre-and post-intervention (24-hour dietary recall) with no significant differences found between ST and DL groups. Specific dietary changes in both groups included increases (p<.05) in dietary fiber (ST from 17.0 to 18.2; DL from 16.38 to 17.8 gms), calcium (ST from 715.7 to 781.9; DL 666.4 to 748.7 mgs), and vegetables (ST 2.5 to 2.8; DL 2.4 to 2.6 servings/day). Although between-intervention group effects were not significant, both culturally-adapted interventions were found to change a selection of key CRC-preventive dietary behaviors.

RESUMO

Methylation of the HLTF gene in colorectal cancer (CRC) cells occurs more frequently in men than women. Progressive epigenetic silencing of HLTF in tumor cells is accompanied by negligible expression in the tumor microenvironment (TME). Cell line-derived xenografts (CDX) were established in control (Hltf+/+) and Hltf-deleted male Rag2-/-IL2rg-/- mice by direct orthotopic cell microinjection (OCMI) of HLTF+/+HCT116 Red-FLuc cells into the submucosa of the cecum. Combinatorial induction of IL6 and S100A8/A9 in the Hltf-deleted TME with ICAM-1 and IL8 in the primary tumor activated a positive feedback loop. The proinflammatory niche produced a major shift in CDX metastasis to peritoneal dissemination compared to controls. Inducible nitric oxide (iNOS) gene expression and transactivation of the iNOS-S100A8/A9 signaling complex in Hltf-deleted TME reprogrammed the human S-nitroso-proteome. POTEE, TRIM52 and UN45B were S-nitrosylated on the conserved I/L-X-C-X2-D/E motif indicative of iNOS-S100A8/A9-mediated S-nitrosylation. 2D-DIGE and protein identification by MALDI-TOF/TOF mass spectrometry authenticated S-nitrosylation of 53 individual cysteines in half-site motifs (I/L-X-C or C-X-X-D/E) in CDX tumors. POTEE in CDX tumors is both a general S-nitrosylation target and an iNOS-S100A8/A9 site-specific (Cys638) target in the Hltf-deleted TME. REL is an example of convergence of transcriptomic-S-nitroso-proteomic signaling. The gene is transcriptionally activated in CDX tumors with an Hltf-deleted TME, and REL-SNO (Cys143) was found in primary CDX tumors and all metastatic sites. Primary CDX tumors from Hltf-deleted TME shared 60% of their S-nitroso-proteome with all metastatic sites. Forty percent of SNO-proteins from primary CDX tumors were variably expressed at metastatic sites. Global S-nitrosylation of proteins in pathways related to cytoskeleton and motility was strongly implicated in the metastatic dissemination of CDX tumors. Hltf-deletion from the TME played a major role in the pathogenesis of inflammation and linked protein S-nitrosylation in primary CDX tumors with spatiotemporal continuity in metastatic progression when the tumor cells expressed HLTF.

RESUMO

BACKGROUND: Wound complications after open infrainguinal revascularization are a frequent cause of patient morbidity, resulting in increased healthcare costs. The purpose of the present study was to assess the effects of closed incision negative pressure therapy (ciNPT) on groin wound complications after infrainguinal bypass and femoral endarterectomy. METHODS: A total of 242 patients who had undergone infrainguinal bypass (n = 124) or femoral endarterectomy (n = 118) at five academic medical centers in New England from April 2015 to August 2019 were randomized to ciNPT (PREVENA; 3M KCI, St Paul, Minn; n = 118) or standard gauze (n = 124). The primary outcome measure was a composite endpoint of groin wound complications, including surgical site infections (SSIs), major noninfectious wound complications, or graft infections within 30 days after surgery. The secondary outcome measures included 30-day SSIs, 30-day noninfectious wound complications, readmission for wound complications, significant adverse events, and health-related quality of life using the EuroQoL 5D-3L survey. RESULTS: The ciNPT and control groups had similar demographics (age, 67 vs 67 years, P = .98; male gender, 71% vs 70%, P = .86; white race, 93% vs 93%, P = .97), comorbidities (previous or current smoking, 93% vs 94%, P = .46; diabetes, 41% vs 48%, P = .20; renal insufficiency, 4% vs 7%, P = .31), and operative characteristics, including procedure type, autogenous conduit, and operative time. No differences were found in the primary composite outcome at 30 days between the two groups (ciNPT vs control: 31% vs 28%; P = .55). The incidence of SSI at 30 days was similar between the two groups (ciNPT vs control: 11% vs 12%; P = .58). Infectious (13.9% vs 12.6%; P = .77) and noninfectious (20.9% vs 17.6%; P = .53) wound complications at 30 days were also similar for the ciNPT and control groups. Wound complications requiring readmission also similar between the two groups (ciNPT vs control: 9% vs 7%; P = .54). The significant adverse event rates were not different between the two groups (ciNPT vs control: 13% vs 16%; P = .53). The mean length of the initial hospitalization was the same for the ciNPT and control groups (5.2 vs 5.7 days; P = .63). The overall health-related quality of life was similar at baseline and at 14 and 30 days postoperatively for the two groups. Although not powered for stratification, we found no differences among the subgroups in gender, obesity, diabetes, smoking, claudication, chronic limb threatening ischemia, bypass, or endarterectomy. On multivariable analysis, no differences were found in wound complications at 30 days for the ciNPT vs gauze groups (odds ratio, 1.4; 95% confidence interval, 0.8-2.6; P = .234). CONCLUSIONS: In contrast to other randomized studies, our multicenter trial of infrainguinal revascularization found no differences in the 30-day groin wound complications for patients treated with ciNPT vs standard gauze dressings. However, the SSI rate was lower in the control group than reported in other studies, suggesting other practice patterns and processes of care might have reduced the rate of groin infections. Further study might identify the subsets of high-risk patients that could benefit from ciNPT.

RESUMO

PURPOSE: Financial hardship can be a major cause of distress among persons with cancer, resulting in chronic stress and impacting physical and emotional health. This paper provides an analysis of the lived experience of cancer patients' financial hardship from diagnosis to post-treatment. METHODS: In-depth interviews were conducted with 26 cancer survivors who reported financial hardship during and/or after treatment. The interviews were analyzed using DedooseTM as an organizational tool, the life course perspective as an organizing theoretical framework, and a thematic analysis tool 1 to answer our research questions. Our analysis identified that timing and sequencing of life transitions and stress proliferation furthered the process of financial stress over time. FINDINGS: Cancer survivors do not experience financial toxicity as a singular process; the experience can be quite different depending on age and life transitions. PRACTICE/POLICY IMPLICATIONS: These findings provide psychosocial oncology providers with a framework for identifying patients at risk for financial distress and addressing the critical needs related to their life stage.

RESUMO

This study examined the relationships between varying levels of depressive symptoms and key dietary indicators of chronic disease risk, sugar-sweetened beverage (SSB) and fruit and vegetable (F + V) consumption, among a racially/ethnically diverse urban population in Los Angeles County (LAC). Analyses were carried out using data from a 2012 cross-sectional health survey of 1401 low-income public health center clients. Participants with a high level of depressive symptoms consumed 30% more SSBs (IRR = 1.30, 95% CI = 1.08, 1.55) than participants with a lower level of these symptoms. Other predictors of higher SSB consumption included being African American/Black (IRR = 1.65, 95% CI = 1.32, 2.05), male (IRR = 1.20, 95% CI = 1.06, 1.35), U.S. born (IRR = 1.32, 95% CI = 1.11, 1.57), and using tobacco (IRR = 1.26, 95% CI = 1.11, 1.43). Similar associations with F + V consumption were not found. Findings suggest that depressive symptoms may influence certain health behaviors in certain groups under certain situations. Policy and practice implications are discussed within this context.

RESUMO

BACKGROUND: Healthful dietary changes after metabolic and bariatric surgery (MBS) may benefit not only patients, but the type and/or availability of foods/beverages in the family home food environment (HFE) overall, thereby reducing obesogenic environmental risks to child offspring in the home. Few studies have investigated the family HFE after MBS. OBJECTIVES: To examine whether the HFE of mothers post-MBS differed from the HFE of mothers of normal weight, overweight, and with obesity using an open home food inventory. SETTING: Cincinnati, Ohio and Newark, Delaware. METHODS: Thirty-two mothers with a child (6-12 yr) participated (8 post-MBS, 8 normal weight, 8 overweight, 8 with obesity) in a pilot study. Research personnel recorded all foods and beverages in the home. Per person total energy and servings of fruits, vegetables, sugar-sweetened beverages, and energy-dense snack foods in the HFE were examined using 1-way analyses of variance and Cohen's d effect sizes. RESULTS: Mothers in the post-MBS group had significantly fewer servings of sugar-sweetened beverages available per person compared with mothers with obesity (P = .01). Effect sizes for group differences indicated total energy, sugar-sweetened beverages, and servings of fruits and vegetables were generally medium to large, most with lower mean values for the post-MBS group relative to comparator groups. CONCLUSION: These findings, while preliminary, highlight areas for future research and add to an emerging literature on obesogenic risks to offspring in the post-MBS home, a known subgroup at high risk for severe obesity.

RESUMO

Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) is a deubiquitylating enzyme that is proposed as a potential therapeutic target in neurodegeneration, cancer, and liver and lung fibrosis. Herein we report the discovery of the most potent and selective UCHL1 probe (IMP-1710) to date based on a covalent inhibitor scaffold and apply this probe to identify and quantify target proteins in intact human cells. IMP-1710 stereoselectively labels the catalytic cysteine of UCHL1 at low nanomolar concentration in cells. We further demonstrate that potent and selective UCHL1 inhibitors block pro-fibrotic responses in a cellular model of idiopathic pulmonary fibrosis, supporting the potential of UCHL1 as a potential therapeutic target in fibrotic diseases.

RESUMO

PURPOSE: To study histo-anatomical imaging features and possible association between prostate volume, capsule thickness and glandular density within the peripheral zone (PZ) of prostates of different sizes. METHODS: Patients were selected who had undergone radical prostatectomy. Specimen selection was based on two factors: first, easy reconstruction of prostate anatomy by the histological slides; and second, based on prostate size. Specimens were chosen with small (< 35 cc) and also with large size (> 80 cc). A total of 20 patients were selected. None of these patients had undergone previous treatment. Computer-based imaging for quantitative measurements of capsule thickness and glandular density within the PZ were performed. Multiple regression analysis was performed to determine the relationship between these measured parameters and the clinical characteristics of these patients. RESULTS: Multiple regression analysis revealed a strong, positive association between prostate size and average capsule thickness; on the contrary, we found a negative correlation between prostate volume and average glandular density. Fibrotic thickness of the capsule was associated with gland atrophy and decreased gland density within the PZ. CONCLUSIONS: The results suggest that BPH may be associated with the development of fibrosis and gland atrophy within the peripheral zone. As 80% of prostate cancer originates from the glandular epithelium within the peripheral zone, this observed phenomenon may explain the inverse relationship between BPH and incidence of prostate cancer well documented in the literature.
