RESUMO

The prevalence of vaping, also known as using e-cigarettes, vapes and vape pens, has prompted a demand for reliable, evidence-based research. However, published literature on the topic of vaping often raises concerns, characterized by serious flaws and a failure to adhere to accepted scientific methodologies. In this narrative review, we analyze popular vaping studies published in medical journals that purport to evaluate the association of vaping and smoking cessation, smoking initiation or health outcomes. We analyzed 24 included studies to identify the questions they claimed to address, stated methods, manner of implementation, discussions, and stated conclusions. After critical appraisal, we noted a multiplicity of flaws in these studies, and identified patterns as to the nature of such flaws. Many studies lacked a clear hypothesis statement: to the extent that a hypothesis could be inferred, the methods were not tailored to address the question of interest. Moreover, main outcome measures were poorly identified, and data analysis was further complicated by failure to control for confounding factors. The body of literature on "gateway" theory for the initiation of smoking was particularly unreliable. Overall, the results and discussion contained numerous unreliable assertions due to poor methods, including data collection that lacked relevance, and assertions that were unfounded. Many researchers claimed to find a causal association while not supporting such findings with meaningful data: the discussions and conclusions of such studies were, therefore, misleading. Herein, we identify the common flaws in the study design, methodology, and implementation found in published vaping studies. We present our summary recommendations for future vaping research. Our aim is to prompt future researchers to adhere to scientific methods to produce more reliable findings and conclusions in the field of vaping research.

RESUMO

We conducted a scoping review of studies on health outcomes from electronic nicotine delivery systems (ENDS). The objective was to identify, narratively synthesize, assess the strength and quality of evidence and critically appraise studies that have reported disease end points associated with the use of ENDS. We included published literature on the health impact of ENDS from 01/01/2015 until 01/02/2020 following the PRISMA guidelines using PubMed, Embase, Scopus and Google Scholar. The database search identified 755 studies, and other sources 265; 37 studies met final eligibility criteria. Levels of evidence included 24(65%) cross-sectional, one (2.7%) case-control and six (16%) case studies, four (11%) cohort studies, one (2.7%) randomized controlled trial (RCT) and one (2.7%) meta-analysis; 27(73%) studies reported only on harms, eight (22%) reported on benefits, two (2%) on benefits and harms. Quality ratings were poor in 20 (54%), fair in 9(24%) and good in 8(22%) of studies. In our review, ENDS was not shown to be causative for harmful cardiovascular disease (CVD) outcomes and shown to be beneficial for hypertensive patients. Switching from cigarettes to e-cigarettes resulted in reduced exacerbations of chronic obstructive pulmonary disease (COPD), with no evidence of long-term deterioration in lung function. Mental Health, cancer and mortality were not adequately studied to form any consensus. Our review has not demonstrated ENDS to be causative of harmful CVD outcomes; furthermore switching from cigarettes to e-cigarettes was associated with improved hypertensive control and reduced exacerbations of COPD, with no evidence of increased asthma risk or long-term respiratory harm. Mental health, cancer and mortality outcomes have not been adequately studied to form a conclusion. Overall, the findings of our review did not provide evidence to counter the consensus held by many that ENDS use is safer than the risks posed from smoking cigarettes.

RESUMO

INTRODUCTION: We tested whether physical activity (PA) engagement is subsequently associated with additional health-promoting behaviours in a large-scale, real-world programme leveraging technology and behavioural science to reward healthy lifestyle behaviours. METHODS: In this observational, longitudinal study, we compared participants' verified and self-reported health behaviours prior to and following their first verified engagement in PA recorded on the Vitality programme between 2014 and 2017. RESULTS: Of 34 061 participants, the mean duration in the programme was 40.1 (SD 12.6) months, and the median time until the first PA was 13.1 (SD 16.6) months, with a mean age of 42.0 (SD 11.1) years and 14 881 (43.7%) being male. Baseline weekly PA minutes were mean 62.8 (SD 129.7), 98 (SD 26.0) and 282.9 (SD 230.0) for the low, moderate and high groups, respectively. In the 12 months following the first PA, the low group increased weekly active minutes by 156% (40 (95% CI 28.6 to 51.0) to 102 (95% CI 94.5 to 109.8)); the moderate group increased weekly active minutes by 60% (85.0 (95% CI 76.4 to 93.5) to 136 (95% CI 130.2 to 141.8)); and no change was seen for the high group. Overall, individuals exhibited an increase of 26% in their weekly active minutes from an average of 130 min (95% CI 121.2 to 139.4) to 164 min (95% CI 157.5 to 169.8). Overall, fruit and vegetable daily servings increased from 2.7 (95% CI 2.6 to 2.8) to 2.9 (95% CI 2.9 to 3.0); Kessler Stress Scores decreased from 17.4 (95% CI 17.2 to 17.6) to 17.0 (95% CI 16.9 to 17.1); sedentary hours decreased from 11.3 (95% CI 11.1 to 11.5) to 10.8 (95% CI 10.7 to 11.0); alcohol consumption decreased from 1.8 (95% CI 1.7 to 2.0) to 1.6 (95% CI 1.5 to 1.7) weekly units; sleep increased with borderline significance from 7.1 (95% CI 7.06 to 7.16) to 7.2 (95% CI 7.13 to 7.20) hours/night. CONCLUSIONS: PA and other health-promoting behaviours improved in parallel. PA was followed by improvements in other health-promoting behaviour.

RESUMO

OBJECTIVE: The present study examined the effect of ingredient bundles (i.e. measured ingredients with recipes) and recipe tastings as a strategy to increase the selection of healthy, target foods (kale, brown rice and whole-wheat pasta). DESIGN: Each of the three conditions was tested once per week for three weeks. The conditions were: Treatment 1 (T1), recipe tastings only; Treatment 2 (T2), ingredient bundle plus recipe tastings; and Control, no intervention. SETTING: A food pantry in Bridgeport, CT, USA.ParticipantsFood pantry clients. RESULTS: Controlling for family size and intervention week, the likelihood of clients in T2 (n 160) selecting at least one target item compared with the Control group (n 160) was 3·20 times higher for kale, 4·76 times higher for brown rice and 7·25 times higher for whole-wheat pasta. Compared with T1 (n 128), T2 clients were 2·67 times more likely to select kale, 7·67 times more likely to select brown rice and 11·43 times more likely to select whole-wheat pasta. No differences between T1 and the Control group were found. CONCLUSIONS: Findings suggest that innovative, nudging strategies such as ingredient bundles may increase appeal of foods and encourage pantry clients to select healthier options.

RESUMO

Globally, approximately one in three of all adults suffer from multiple chronic conditions (MCCs). This review provides a comprehensive overview of the resulting epidemiological, economic and patient burden. There is no agreed taxonomy for MCCs, with several terms used interchangeably and no agreed definition, resulting in up to three-fold variation in prevalence rates: from 16% to 58% in UK studies, 26% in US studies and 9.4% in Urban South Asians. Certain conditions cluster together more frequently than expected, with associations of up to three-fold, e.g. depression associated with stroke and with Alzheimer's disease, and communicable conditions such as TB and HIV/AIDS associated with diabetes and CVD, respectively. Clusters are important as they may be highly amenable to large improvements in health and cost outcomes through relatively simple shifts in healthcare delivery. Healthcare expenditures greatly increase, sometimes exponentially, with each additional chronic condition with greater specialist physician access, emergency department presentations and hospital admissions. The patient burden includes a deterioration of quality of life, out of pocket expenses, medication adherence, inability to work, symptom control and a high toll on carers. This high burden from MCCs is further projected to increase. Recommendations for interventions include reaching consensus on the taxonomy of MCC, greater emphasis on MCCs research, primary prevention to achieve compression of morbidity, a shift of health systems and policies towards a multiple-condition framework, changes in healthcare payment mechanisms to facilitate this change and shifts in health and epidemiological databases to include MCCs.

RESUMO

OBJECTIVES: For centuries, the concept of race, a uniquely pervasive social construct, has often complicated dialogue and interactions between groups of people. This study assessed perceptions and attitudes of faculty and trainees with varied racial backgrounds within graduate medical and psychology programs. Self-reported responses addressed potential barriers and facilitating factors required for meaningful conversations about race. METHODS: A brief 18-question survey was developed and administered electronically to three professional and academic Listservs within a large metropolitan city in northeast United States. Quantitative and qualitative analysis were conducted using SPSS Statistical Software and Text analyzer. RESULTS: Results revealed that among participants (N = 57) a majority experienced cross-racial supervision, and more than half indicated engaging in conversations about race within supervision. Respondents endorsed lack of comfort and lack of opportunity/time as significant barriers to discussing race within supervision. When race-related dialogues occurred, a majority of supervisees and supervisors found it beneficial. Most Supervisors of Color(a) actively initiated these conversations in supervision, while White supervisees endorsed the least benefit from these conversations. Contrary to our expectations, few respondents endorsed limited training as a barrier. DISCUSSION: The current study revealed cross-racial dialogues about race may be occurring frequently in supervisory relationships. Supervisees of Color reported benefiting from these dialogues, in contrast to their White counterparts, who endorsed the least benefit. Lack of comfort in supervisory relationships appears to be a significant barrier to having these conversations. Therefore, it is important for supervisors to create supervisory relationships emphasizing safety and comfort. Directions for future research are discussed.

RESUMO

OBJECTIVE: This study examines religion and spirituality among advanced cancer patients from an underserved, ethnically-diverse population by exploring patient conceptualizations of religion and spirituality, the role of religion and spirituality in coping with cancer, and patient interest in spiritual support. METHOD: Qualitative semi-structured interviews were conducted with patients who had participated in a study of a "mind-body" support group for patients with all cancer types. Analysis based on grounded theory was utilized to identify themes and theoretical constructs. RESULTS: With regard to patient conceptualizations of religion and spirituality, three categories emerged: (1) Spirituality is intertwined with organized religion; (2) Religion is one manifestation of the broader construct of spirituality; (3) Religion and spirituality are completely independent, with spirituality being desirable and religion not. Religion and spirituality played a central role in patients' coping with cancer, providing comfort, hope, and meaning. Patients diverged when it came to spiritual support, with some enthusiastic about interventions incorporating their spiritual values and others stating that they already get this support through religious communities. SIGNIFICANCE OF RESULTS: Spirituality plays a central role in the cancer experience of this underserved ethnically-diverse population. While spirituality seems to be a universal concern in advanced cancer patients, the meaning of spirituality differs across individuals, with some equating it with organized religion and others taking a more individualized approach. It is important that psychosocial interventions are developed to address this concern. Future research is needed to further explore the different ways that patients conceptualize spirituality and to develop spiritually-based treatments that are not "one size fits all."

RESUMO

OBJECTIVES: Subjective reports on the effectiveness of and satisfaction with writing interventions in medical populations have indicated that they can have a profound impact on patients. Further, past research on these programs has demonstrated that they can lead to a number of different positive outcomes depending on the personal characteristics of the participating patients and the type of writing with which they are tasked. For this reason, a flexible and individually tailored writing intervention may be particularly effective for patients, molding its approach to their desires and backgrounds. This paper examines Visible Ink, a writing program for cancer patients at Memorial Sloan-Kettering Cancer Center (MSKCC) that follows this model. METHODS: At Visible Ink's First Fall Writing Festival in November 2012, an optional survey was provided to all program participants in attendance, capturing both quantitative and qualitative information on patient experiences in the program. Twenty-nine surveys were completed. RESULTS: The program appears to have a variety of positive effects, including fostering personal growth and providing a positive distraction. Respondents reported that they write in a number of different genres on topics both related and not related to their illnesses, which supports the flexible model of the program. All respondents indicated that they would recommend the program to others, and satisfaction with the program's general approach (i.e., individualized work with a writing coach) was unanimous. A few areas for potential improvement were also identified, most of which involved expanding the services and events offered by the program. SIGNIFICANCE OF RESULTS: Despite the limitations of this survey (e.g., small sample size and low response rate), its results support the promise of the Visible Ink model and demonstrate participants' satisfaction with the program. Future research can more thoroughly examine Visible Ink's effectiveness, and additional resources could enable the program to expand.

RESUMO

OBJECTIVE: Optimism and social support serve as protective factors against distress in medically ill patients. Very few studies have specifically explored the ways in which these variables interact to impact quality of life (QOL), particularly among patients with advanced cancer. The present study examined the role of optimism as a moderator of the relationship between social support and anxiety, depression, hopelessness, and QOL among patients with advanced cancer. METHODS: Participants (N = 168) completed self-report assessments of psychosocial, spiritual, and physical well-being, including social support, optimism, hopelessness, depressive and anxious symptoms, and QOL. Hierarchical multiple regression analyses were conducted to determine the extent to which social support and optimism were associated with depressive and anxious symptomatology, hopelessness and QOL, and the potential role of optimism as a moderator of the relationship between social support and these variables. RESULTS: Higher levels of optimism were significantly associated with fewer anxious and depressive symptoms, less hopelessness, and better QOL. Higher levels of perceived social support were also significantly associated with better QOL. Additionally, optimism moderated the relationship between social support and anxiety, such that there was a strong negative association between social support and anxiety for participants with low optimism. CONCLUSIONS: This study highlights the importance of optimism and social support in the QOL of patients with advanced cancer. As such, interventions that attend to patients' expectations for positive experiences and the expansion of social support should be the focus of future clinical and research endeavors.

RESUMO

PURPOSE: Spirituality is an important component of the cancer experience. This study aims to assess characteristics of spiritual health following a cancer diagnosis, and evaluate the relationship between spiritual change and the use of complementary and alternative medicine (CAM) among a population-based cohort of cancer survivors. METHOD: A mailed, cross-sectional survey was completed by 614 cancer survivors identified through the Pennsylvania Cancer Registry. All subjects were 3 to 4.5 years postdiagnosis. Relationships between various characteristics of spiritual health and CAM use were examined, along with clinical and sociodemographic factors. RESULTS: Although large proportions of individuals reported that having cancer had positively affected their spiritual well-being (eg, 40.3% experienced highly positive spiritual changes, 68% felt a high sense of purpose, 75.9% reported being very hopeful), some individuals experienced negative spiritual change (36.1%) and continued to experience high levels of uncertainty (27.2%). In multivariate analyses, those survivors who felt spiritual life became more important (adjusted odds ratio [AOR] = 1.92, 95% confidence interval (CI) = 1.21-3.04, P = .006), or experienced positive changes resulting from the cancer experience (AOR = 1.99, 95% CI = 1.26-3.15, P = .003), were more likely to use CAM than those who stated otherwise. CONCLUSIONS: Having cancer affects many different aspects of spiritual well-being, both positively and negatively. Positive changes and increased spiritual importance appear to be associated with the use of CAM. Prospective research is needed to test whether integrating CAM into conventional cancer care systems will facilitate positive, spiritually transformative processes among diverse groups of cancer survivors.

RESUMO

Stargazin is a transmembrane alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor regulatory protein that controls the surface and synaptic expression of AMPA-type glutamate receptors (AMPARs). Synaptic anchoring of AMPARs is influenced by the interaction between stargazin's C-terminal post-synaptic density-95 (PSD-95)/discs large/zona occludens-1 (PDZ) ligand and the synaptic scaffolding protein PSD-95. Phosphorylation of the stargazin PDZ ligand by protein kinase A (PKA) disrupts stargazin's interaction with PSD-95, but whether this phosphorylation plays a role in activity-dependent regulation of stargazin/AMPAR synaptic trafficking is unknown. Here, we show that stargazin is phosphorylated within the PDZ ligand at threonine residue 321 (T321) by mitogen-activated protein kinases (MAPKs) as well as PKA. By expressing constructs that selectively block T321 phosphorylation by either PKA or MAPKs, we show that stargazin T321 phosphorylation is required for activity-dependent changes in stargazin synaptic clustering in dissociated rat hippocampal neuron cultures. Specifically, we find that mutations that block stargazin T321 phosphorylation by PKA prevent activity-dependent increases in stargazin synaptic clustering, whereas a point mutant that blocks MAPK phosphorylation of T321 prevents activity-dependent decreases in stargazin synaptic clustering. Taken together, our studies implicate phosphorylation of stargazin T321 by PKA and MAPKs in bidirectional control of stargazin/AMPAR synaptic clustering during synaptic plasticity.
