Descripción de la terapia cognitivo-conductual para la ansiedad en pacientes con cáncer terminal
The aim of this study was to describe the major components and features of cognitive behavioral therapy when used to treat anxiety in patients with terminal cancer. Specifically, four components of cognitive behavioral therapy for terminal cancer patients are described: 1) principles of cognitive behavioral therapy 2) relaxation techniques 3) identification and restructuring negative thoughts 4) planning activities. Similarly, the average duration of cognitive behavioral therapy, number of sessions, application intervals and major problems reported when therapy is applied are described. Finally, recommendations for the implementation of therapy and for the development of future research in this field are described.El objetivo de este trabajo es describir los principales componentes y características de la terapia cognitivo conductual cuando se utiliza para tratar problemas de ansiedad en pacientes con cáncer terminal.

Genitourinary quality-of-life comparison between urethral sparing prostate stereotactic body radiation therapy monotherapy and virtual high-dose-rate brachytherapy boost
Purpose: Although radiation dose escalation improves prostate cancer disease control, it can cause increased toxicity. Genitourinary (GU) symptoms after prostate radiation therapy affect patient health-related quality of life (QoL). We compared patient-reported GU QoL outcomes following 2 alternative urethral sparing stereotactic body radiation therapy regimens.
Methods and Materials: Expanded Prostate Cancer Index Composite (EPIC)–26 GU scores were compared between 2 urethral sparing stereotactic body radiation therapy trials. The SPARK trial prescribed a “Monotherapy” dose of 36.25 Gy in 5 fractions to the prostate. The PROMETHEUS trial prescribed 2 phases: a 19- to 21-Gy in 2 fractions “Boost” to the prostate, followed by 46 Gy in 23 fractions or 36 Gy in 12 fractions. The biological effective dose (BED) for urethral toxicity was 123.9 Gy for Monotherapy and 155.8 to 171.2 Gy for Boost. Mixed effects logistic regression models were utilized to estimate the difference in the odds of a minimal clinically important change from baseline EPIC-26 GU score between regimens at each follow-up.
Results: 46 Monotherapy and 149 Boost patients completed baseline EPIC-26 scoring. Mean EPIC-26 GU scores revealed statistically superior urinary incontinence outcomes for Monotherapy at 12 months (mean difference, 6.9; 95% confidence interval [CI], 1.6-12.1; P = .01) and 36 months (mean difference, 9.6; 95% CI, 4.1-15.1; P < .01). Monotherapy also revealed superior mean urinary irritative/obstructive outcomes at 12 months (mean difference, 6.9; 95% CI, 2.0-12.9; P < .01) and 36 months (mean difference, 6.3; 95% CI, 1.9-10.8; P < .01). For both domains and at all time points, the absolute differences were <10%. There were no significant differences in the odds of reporting a minimal clinically important change between regimens at any time point.
Conclusions: Even in the presence of urethral sparing, the higher BED delivered in the Boost schedule may have a small adverse effect on GU QoL compared with Monotherapy. However, this did not translate to statistically significant differences in minimal clinically important changes. Whether the higher BED of the boost arm offers an efficacy advantage is being investigated in the Trans Tasman Radiation Oncology Group 18.01 NINJA randomized trial
Observation of Binding and Rotation of Methane and Hydrogen within a Functional Metal-Organic Framework
The key requirement for a portable
store of natural gas is to maximize
the amount of gas within the smallest possible space. The packing
of methane (CH<sub>4</sub>) in a given storage medium at the highest
possible density is, therefore, a highly desirable but challenging
target. We report a microporous hydroxyl-decorated material, MFM-300(In)
(MFM = Manchester Framework Material, replacing the NOTT designation),
which displays a high volumetric uptake of 202 v/v at 298 K and 35
bar for CH<sub>4</sub> and 488 v/v at 77 K and 20 bar for H<sub>2</sub>. Direct observation and quantification of the location, binding,
and rotational modes of adsorbed CH<sub>4</sub> and H<sub>2</sub> molecules
within this host have been achieved, using neutron diffraction and
inelastic neutron scattering experiments, coupled with density functional
theory (DFT) modeling. These complementary techniques reveal a very
efficient packing of H<sub>2</sub> and CH<sub>4</sub> molecules within
MFM-300(In), reminiscent of the condensed gas in pure component crystalline
solids. We also report here, for the first time, the experimental
observation of a direct binding interaction between adsorbed CH<sub>4</sub> molecules and the hydroxyl groups within the pore of a material.
This is different from the arrangement found in CH<sub>4</sub>/water
clathrates, the CH<sub>4</sub> store of nature
The incidence of ventilator-associated pneumonia using the PneuX System with or without elective endotracheal tube exchange: A pilot study
<p>Abstract</p> <p>Background</p> <p>The PneuX System is a novel endotracheal tube and tracheal seal monitor, which has been designed to minimise the aspiration of oropharyngeal secretions. We aimed to determine the incidence of ventilator-associated pneumonia (VAP) in patients who were intubated with the PneuX System and to establish whether intermittent subglottic secretion drainage could be performed reliably and safely using the PneuX System.</p> <p>Findings</p> <p>In this retrospective observational study, data was collected from 53 sequential patients. Nine (17%) patients were initially intubated with the PneuX System and 44 (83%) patients underwent elective exchange to the PneuX System. There were no episodes of VAP while the PneuX System was <it>in situ</it>. On an intention to treat basis, the incidence VAP was 1.8%. There were no complications from, or failure of, subglottic secretion drainage during the study.</p> <p>Conclusions</p> <p>Our study demonstrates that a low incidence of VAP is possible using the PneuX System. Our study also demonstrates that elective exchange and intermittent subglottic secretion drainage can be performed reliably and safely using the PneuX System.</p
An Indocyanine Green-Based Nanoprobe for In Vivo Detection of Cellular Senescence
There is an urgent need to improve conventional cancer-treatments by preventing detrimental side effects, cancer recurrence and metastases. Recent studies have shown that presence of senescent cells in tissues treated with chemo- or radiotherapy can be used to predict the effectiveness of cancer treatment. However, although the accumulation of senescent cells is one of the hallmarks of cancer, surprisingly little progress has been made in development of strategies for their detection in vivo. To address a lack of detection tools, we developed a biocompatible, injectable organic nanoprobe (NanoJagg), which is selectively taken up by senescent cells and accumulates in the lysosomes. The NanoJagg probe is obtained by self-assembly of indocyanine green (ICG) dimers using a scalable manufacturing process and characterized by a unique spectral signature suitable for both photoacoustic tomography (PAT) and fluorescence imaging. In vitro, ex vivo and in vivo studies all indicate that NanoJaggs are a clinically translatable probe for detection of senescence and their PAT signal makes them suitable for longitudinal monitoring of the senescence burden in solid tumors after chemotherapy or radiotherapy.</p

Baseline Features and Reasons for Nonparticipation in the Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) Study, a Colorectal Cancer Screening Trial.
IMPORTANCE: The Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) randomized clinical trial sought to recruit 50 000 adults into a study comparing colorectal cancer (CRC) mortality outcomes after randomization to either an annual fecal immunochemical test (FIT) or colonoscopy.
OBJECTIVE: To (1) describe study participant characteristics and (2) examine who declined participation because of a preference for colonoscopy or stool testing (ie, fecal occult blood test [FOBT]/FIT) and assess that preference\u27s association with geographic and temporal factors.
DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study within CONFIRM, which completed enrollment through 46 Department of Veterans Affairs medical centers between May 22, 2012, and December 1, 2017, with follow-up planned through 2028, comprised veterans aged 50 to 75 years with an average CRC risk and due for screening. Data were analyzed between March 7 and December 5, 2022.
EXPOSURE: Case report forms were used to capture enrolled participant data and reasons for declining participation among otherwise eligible individuals.
MAIN OUTCOMES AND MEASURES: Descriptive statistics were used to characterize the cohort overall and by intervention. Among individuals declining participation, logistic regression was used to compare preference for FOBT/FIT or colonoscopy by recruitment region and year.
RESULTS: A total of 50 126 participants were recruited (mean [SD] age, 59.1 [6.9] years; 46 618 [93.0%] male and 3508 [7.0%] female). The cohort was racially and ethnically diverse, with 748 (1.5%) identifying as Asian, 12 021 (24.0%) as Black, 415 (0.8%) as Native American or Alaska Native, 34 629 (69.1%) as White, and 1877 (3.7%) as other race, including multiracial; and 5734 (11.4%) as having Hispanic ethnicity. Of the 11 109 eligible individuals who declined participation (18.0%), 4824 (43.4%) declined due to a stated preference for a specific screening test, with FOBT/FIT being the most preferred method (2820 [58.5%]) vs colonoscopy (1958 [40.6%]; P \u3c .001) or other screening tests (46 [1.0%] P \u3c .001). Preference for FOBT/FIT was strongest in the West (963 of 1472 [65.4%]) and modest elsewhere, ranging from 199 of 371 (53.6%) in the Northeast to 884 of 1543 (57.3%) in the Midwest (P = .001). Adjusting for region, the preference for FOBT/FIT increased by 19% per recruitment year (odds ratio, 1.19; 95% CI, 1.14-1.25).
CONCLUSIONS AND RELEVANCE: In this cross-sectional analysis of veterans choosing nonenrollment in the CONFIRM study, those who declined participation more often preferred FOBT or FIT over colonoscopy. This preference increased over time and was strongest in the western US and may provide insight into trends in CRC screening preferences
International genome-wide meta-analysis identifies new primary biliary cirrhosis risk loci and targetable pathogenic pathways.
Primary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10(-8)) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine-cytokine pathways, for which relevant therapies exist
