Purpose: Clinical guidelines recommend early palliative care for patients with advanced lung cancer. In rural and underserved community oncology practices with limited resources, both primary palliative care from an oncologist and specialty palliative care are needed to address patients' palliative care needs. The aim of this study is to describe community oncology clinicians' primary palliative care practices and perspectives on integrating specialty palliative care into routine advanced lung cancer treatment in rural and underserved communities., Methods: Participants were clinicians recruited from 15 predominantly rural community oncology practices in Kentucky. Participants completed a one-time survey regarding their primary palliative care practices and knowledge, barriers, and facilitators to integrating specialty palliative care into advanced-stage lung cancer treatment., Results: Forty-seven clinicians (30% oncologists) participated. The majority (72.3%) of clinicians worked in a rural county. Over 70% reported routinely asking patients about symptom and physical function concerns, whereas less than half reported routinely asking about key prognostic concerns. Roughly 30% held at least one palliative care misconception (e.g., palliative care is for only those who are stopping cancer treatment). Clinician-reported barriers to specialty palliative care referrals included fear a referral would send the wrong message to patients (77%) and concern about burdening patients with appointments (53%). Notably, the most common clinician-reported facilitator was a patient asking for a referral (93.6%)., Conclusion: Educational programs and outreach efforts are needed to inform community oncology clinicians about palliative care, empower patients to request referrals, and facilitate patients' palliative care needs assessment, documentation, and standardized referral templates., (© 2024.

While many cancer patients who use tobacco try to quit post-diagnosis, some prefer to quit without using tobacco treatment, despite evidence against unassisted quit attempts. This study aimed to understand the rationale for some cancer patients' desire to quit tobacco without assistance. Thirty-five adult cancer patients who currently used tobacco and declined tobacco treatment because of the desire to quit unassisted provided data via a standardized questionnaire and a semi-structured interview. The sample was predominately White, non-Hispanic (85.71%) and female (68.57%). The most common cancer site was gynecological. Key themes that emerged from the interviews were: self-reliance, willpower, social norms, and negative attitudes toward tobacco treatment. The most frequently endorsed barrier to tobacco treatment was " I know others who have quit without tobacco treatment" (82.86%). This study with cancer patients identified affective, cognitive, and personality factors related to quitting unassisted, and social and systemic reasons to not use tobacco treatment., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Many cancer patients who smoke cigarettes want to quit. Unfortunately, many of these cancer patients prefer to quit without the aid of pharmacotherapy or behavioral counseling. The teachable moment of cancer diagnosis might still position these cancer patients to make meaningful changes in their smoking behavior, but no study has documented the trajectory of smoking cessation outcomes among cancer patients who want to quit "on their own." This study aimed to fill this gap in the literature., Methods: In this mixed-methods, longitudinal study, 35 cancer patients who declined tobacco treatment because of the desire to quit "on their own" provided data via three surveys and 1-2 semi-structured interviews. The observation period spanned 60 days. Participants were recently diagnosed at and recruited from outpatient cancer clinics., Results: Participants were mostly female (68.57%), White, non-Hispanic (85.71%), unemployed due to disability (57.14%), and rural residents (54.29%). Across time, 43.76% of participants achieved 50% smoking reduction, 21.88% achieved 3-day floating abstinence, 18.75% achieved 7-day floating abstinence, and 12.50% achieved 30-day point-prevalence abstinence. Key themes that emerged from the interviews centered on intention and confidence to quit and types of tobacco treatment used/received., Conclusions: This study with cancer patients who desired to quit smoking without assistance found some evidence of quit success, but success waned as criteria grew more stringent. Results showed participants' initial intention to quit unassisted was quite strong, as few reported tobacco treatment use. Interventions to increase the uptake of evidence-based tobacco treatment among cancer patients are sorely needed., Implications: The preference to quit smoking without assistance is common among cancer patients, even given lack of evidence supporting its effectiveness. This study is the first to explore the trajectory of smoking cessation outcomes among cancer patients who desire to quit without assistance. These data can be used to develop interventions to increase the uptake of tobacco treatment and increase quit success among cancer patients., (© The Author(s) 2023.

Purpose: For cancer survivors, social functioning greatly influences other quality of life dimensions. While there is potential for differences in social functioning to vary as a function of geographic residence, few studies examine the social functioning of rural cancer survivors specifically. This study aims to help fill this gap., Methods: This was an embedded mixed-methods study where all participants completed a questionnaire, and some were purposively selected to complete an interview to gather more information about social functioning (ie, social roles, activities, network, support, and constraint). Participants (n = 93; 63% rural) were recruited through a state cancer registry and cancer care facility. Participants were predominately White, non-Hispanic (92.47%), roughly half female (54.84%), and on average, diagnosed in the past two years (SD = 1.68), and 61.45 (SD = 10.87) years old., Findings: Few differences in the social functioning of rural and nonrural participants were found on questionnaires, though rural participants reported larger networks and more overall support. Across groups, common themes in the interview data were the experience of both social support (eg, instrumental support) and social constraint (eg, others minimizing participants' problems or sharing their own negative experiences)., Conclusions: This was the first cancer survivorship study to thoroughly examine social functioning by geographic residence. Rural cancer survivors described some unique strengths, but major group differences were not apparent. All participants highlighted situations when others, even with good intentions, were unhelpful to them. Future interventions to improve social functioning could work to dispel the belief that cancer survivors should handle their cancer on their own., (© 2022 National Rural Health Association.)

Purpose: Despite clinical guidelines, palliative care is underutilized during advanced stage lung cancer treatment. To inform interventions to increase its use, patient-level barriers and facilitators (i.e., determinants) need to be characterized, especially among patients living in rural areas or those receiving treatment outside academic medical centers., Methods: Between 2020 and 2021, advanced stage lung cancer patients (n = 77; 62% rural; 58% receiving care in the community) completed a one-time survey assessing palliative care use and its determinants. Univariate and bivariate analyses described palliative care use and determinants and compared scores by patient demographic (e.g., rural vs. urban) and treatment setting (e.g., community vs. academic medical center) factors., Results: Roughly half said they had never met with a palliative care doctor (49.4%) or nurse (58.4%) as part of cancer care. Only 18% said they knew what palliative care was and could explain it; 17% thought it was the same as hospice. After palliative care was distinguished from hospice, the most frequently cited reasons patients stated they would not seek palliative care were uncertainty about what it would offer (65%), concerns about insurance coverage (63%), difficulty attending multiple appointments (60%), and lack of discussion with an oncologist (59%). The most common reasons patients stated they would seek palliative care were a desire to control pain (62%), oncologist recommendation (58%), and coping support for family and friends (55%)., Conclusion: Interventions should address knowledge and misconceptions, assess care needs, and facilitate communication between patients and oncologists about palliative care., (© 2023.

Introduction: This intensive longitudinal study describes key events in the process of smoking cessation after a new head and neck cancer (HNC) diagnosis. Prior longitudinal studies show some cancer patients quit, while others continue to smoke, but details about the pattern in which these discrete outcomes arise are scarce. This study is meant to help rectify this gap in the literature., Aims and Methods: Participants were 42 HNC patients who reported current smoking at enrollment. Participants were recruited from an outpatient oncology clinic and completed a baseline questionnaire prior to begin a 30-day daily assessment., Results: Few participants (9.52%) achieved 30-day continuous abstinence from smoking. On average, participants reported 9.64 ± 11.93 total days of abstinence. Nearly, all (94.44%, n = 34) participants made at least one quit attempt, with an average of 16.94 ± 11.30 quit attempt days. Fewer participants were able to achieve a 24-hour quit attempt (52.78%, n = 19), with a corresponding average of 5.50 ± 8.69 24-hour days. The median time to first 24-hour quit attempt was 13 days after enrollment. Based on smoking behavioral patterns, participants were categorized into five groups, the most common being "persistent attempters," which involved unsuccessful quit attempts throughout the study. Only 45% of participants (n = 19) used evidence-based treatment, the most common being cessation medication., Conclusions: This intensive longitudinal study found that cancer diagnosis can spur a lot of efforts to quit smoking. Unfortunately, this study suggests that many quit attempts are short lived, possibly a result of an absence or insufficient use of evidence-based treatments., Implications: For adults who are current smokers at the time of cancer diagnosis, there is a high likelihood of persistent cigarette smoking and use of other tobacco products in the weeks and months after a cancer diagnosis. Furthermore, this study shows that while a lot of quit attempts may occur, few are successful, which may be partly attributable to the low use of evidence-based tobacco treatment. Future research with cancer patients should aim to identify predictors of quit attempts and abstinence as well as treatment utilization., (© The Author(s) 2022.

Studies of life-history variation across a species range are crucial for ecological understanding and successful conservation. Here, we examined the growth and age of Wels catfish (Silurus glanis) in Sweden, which represent the northernmost populations in Europe. A total of 1183 individuals were captured, marked and released between 2006 and 2020. Mark-recapture data from 162 individuals (size range: 13-195 cm) were used to estimate von Bertalanffy growth curve parameters which revealed very slow growth rates compared to catfish within the core distribution area (central Europe). The fitted von Bertalanffy growth curve predicted a 150 cm catfish to be around 40 years old, while the largest recaptured individual (length 195 cm) was estimated to be 70 (95% CI 50-112) years old. This was substantially older than the previously documented maximum age of a catfish. The weight at length relationships in these northern peripheral populations were similar to those documented for catfish in central Europe indicating that resources did not constrain growth. This indicates that the slow growth and exceptional high age in the northern catfish populations are the result of lower temperatures and/or local adaptations., (© 2022. The Author(s).)

Introduction: Theoretically, a cancer diagnosis has the potential to spur health behavior changes in physical activity, diet, substance use, medication adherence, and the like. The Teachable Moment heuristic is a parsimonious, transtheoretical framework for understanding the conditions under which behavior change might occur, with constructs that include affective, cognitive, and social factors. Application of the Teachable Moment to smoking cessation after cancer diagnosis might aid selection of predictors in observational studies and inform how to optimally design interventions to promote quit attempts and sustain abstinence, as many smoking cessation interventions for cancer survivors do not yield positive outcomes., Aims and Methods: This scoping review of 47 studies that span nearly 20 years of literature examines the measurement of the Teachable Moment constructs and what empirical support they have in explaining cancer survivors' smoking behavior., Results: From this review, it appears the construct of affective response is more widely explored than risk perceptions, social role, and self-concept. Strong, negative affective responses (e.g., anxiety, general distress) may be a powerful contributor to continued smoking after a cancer diagnosis. Risk perceptions may also play a role in smoking behavior, such that never and former smokers espouse stronger perceptions of smoking-related risks than current smokers. Finally, due to a paucity of studies, the role of cancer survivors' self-concept (e.g., identity as a "cancer survivor") and changes in their social role (e.g., employee, athlete) are unclear contributors to their smoking behavior. In summary, the Teachable Moment holds promise in its application to smoking cessation after a cancer diagnosis, though more direct research is needed., Conclusions: This scoping review of the scientific literature is the first formal test of the extent to which cancer diagnosis has been explored as a "teachable moment" for smoking cessation, with results that provide insight into issues of measurement precision and breadth as well as empirical support of the "teachable moment" heuristic., (© The Author(s) 2021.

We study and demonstrate the nonlinear frequency conversion of broadband optical pulses from 1053 nm to 351 nm using sum-frequency generation with a narrowband pulse at 526.5 nm. The combination of angular dispersion and noncollinearity cancels out the wave-vector mismatch and its frequency derivative, yielding an order-of-magnitude increase in spectral acceptance compared to conventional tripling. This scheme can support the nonlinear frequency conversion of broadband spectrally incoherent nanosecond pulses generated by high-energy lasers and optical parametric amplifiers to mitigate laser-plasma instabilities occurring during interaction with a target. The experimental results obtained with KDP crystals are in excellent agreement with modeling, demonstrating the generation of spectrally incoherent pulses with a bandwidth larger than 10 THz at 351 nm.

We present a broadband optical parametric chirped pulse amplification (OPCPA) system delivering 4 J pulses at a repetition rate of 5 Hz. It will serve as a frontend for the 1.5 kJ, <150  fs, 10 PW laser beamline currently under development by a consortium of National Energetics and Ekspla. The spectrum of the OPCPA system is precisely controlled by arbitrarily generated waveforms of the pump lasers. To fully exploit the high flexibility of the frontend, we have developed a 1D model of the system and an optimization algorithm that predicts suitable pump waveform settings for a desired output spectrum. The OPCPA system is shown to have high efficiency, a high-quality top-hat beam profile, and an output spectrum demonstrated to be shaped consistently with the theoretical model.

Many organisms undertake migrations between foraging and breeding habitats and while it is assumed that reproductive timing affects fitness, little is known about the degree of individual consistency, and about the causes and consequences of individual variation in migratory timing in organisms other than birds. Here, we report on a 6-year mark-recapture study, including 2048 individuals, of breeding migration in anadromous pike (Esox lucius), an iteroparous top-predatory fish that displays homing behaviour. By repeated sampling across years at a breeding site, we first quantify individual variation both within and between breeding events and then investigate phenotypic correlates and fitness consequences of arrival timing to the breeding site. Our data demonstrate that males arrive before females, that large males arrive later than small males, that the timing of breeding migration varies among years and that individuals are consistent in their timing across years relative to other individuals in the population. Furthermore, data on return rates indicate that arrival time is under stabilizing viability selection, and that individuals who are more flexible in their timing of arrival during the first reproductive years survive longer compared with less flexible individuals. Finally, longitudinal data demonstrate that individuals consistently fine-tune their arrival timing across years, showing that the timing of arrival to breeding sites is influenced by experience. These findings represent rare evidence of how between- and within-individual variations in migratory timing across breeding events are correlated with phenotypic and fitness traits in an ecologically important keystone species. Our results emphasize the importance of considering variation in migratory timing both between and within individuals in studies investigating the fitness consequences of migratory behaviour and have implications for future management., (© 2015 The Authors.

We present the design and performance of the Texas Petawatt Laser, which produces a 186 J 167 fs pulse based on the combination of optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification. OPCPA provides the majority of the gain and is used to broaden and shape the seed spectrum, while amplification in Nd:glass accounts for >99% of the final pulse energy. Compression is achieved with highly efficient multilayer dielectric gratings.

According to an analyst report from Smith Barney, the market for managed care information systems is about $2 billion, growing to more than $5 billion by 2000. Nonetheless, these systems must prove a cost-effective for managed care organizations. Systems should add value and, over time, offer a return on investment. These goals are accomplished through solutions that recognize and anticipate expanding information requirements in the evolving healthcare market.
