RESUMO

PURPOSE: The objective of this study was to identify and assess patient and disease characteristics associated with an increased risk of disease progression in men with prostate cancer on active surveillance. METHODS: We studied patients with low-risk (ISUP GG1) or favorable intermediate-risk (ISUP GG2) PCa. All patients had at least one repeat biopsy. Disease progression was the primary outcome of this study, based on pathological upgrading. Univariate and multivariate Cox proportional hazard analyses were used to evaluate the association between covariates and disease progression. RESULTS: In total, 240 men were included, of whom 198 (82.5%) were diagnosed with low-risk PCa and 42 (17.5%) with favorable intermediate-risk PCa. Disease progression was observed in 42.9% (103/240) of men. Index lesion > 10 mm (HR = 2.85; 95% CI 1.74-4.68; p < 0.001), MRI (m)T-stage 2b/2c (HR = 2.52; 95% CI 1.16-5.50; p = 0.02), highest PI-RADS score of 5 (HR 3.05; 95% CI 1.48-6.28; p = 0.002) and a higher PSA level (HR 1.06; 95% CI 1.01-1.11; p = 0.014) at baseline were associated with disease progression on univariate analysis. Multivariate analysis showed no significant baseline predictors of disease progression. CONCLUSION: In AS patients with low-risk or favorable intermediate-risk PCa, diameter of index lesion, MRI (m)T-stage, height of the PI-RADS score and the PSA level at baseline are significant predictors of disease progression to first repeat biopsy.

RESUMO

INTRODUCTION: The prognosis and optimal treatment approach for stage I mixed germ cell cancers of the testis are not well-established. This study aimed to assess contemporary treatment rates and their correlation with the cancer-specific mortality (CSM) and other-cause mortality (OCM) in patients with stage I testicular mixed germ cell tumors (TMGCT) who underwent orchiectomy, comparing surveillance with active treatment, including chemotherapy (CHT) and retroperitoneal lymph node dissection (RPLND). METHODS: Retrospective analysis of clinical data from stage I TMGCT patients who underwent orchiectomy was conducted using the Surveillance, Epidemiology, and End Results database from 2004 to 2019. The annual percentage change (APC) in the use of surveillance, postoperative CHT, and RPLND was examined. Propensity score matching (PSM) and cumulative incidence, analyses were employed to compare differences in CSM and OCM between surveillance and active treatment, as well as between CHT and RPLND. Multivariate competing-risks regression models were utilized to investigate independent factors affecting CSM and OCM among stage I TMGCT patients. RESULTS: The study included 5743 individuals with stage I TMGCT that underwent surveillance (61.6%), CHT(27.2%), or RPLND (11.2%). Among them, 82 deaths were attributed to TMGCT, and 82 deaths resulted from other causes. Surveillance rates increased over time (APC: 0.635%, P = 0.008), as did CHT rates (APC: 0.863%, P < 0.001), while RPLND rates declined (APC: -0.96%, P < 0.001). After PSM, multivariate competing-risks regression analysis showed that, active treatment, compared to surveillance, was not an independent factor for CSM and OCM. In contrast, when compared to CHT, RPLND was an independent factor associated with lower CSM (hazard ratio = 0.247, 95% confidence interval: 0.08-0.761; P = 0.015), but not OCM (hazard ratio = 0.946, 95% confidence interval: 0.377-2.37; P = 0.91). CONCLUSIONS: Surveillance and CHT rates have increased over time for patients with stage I TMGCT following initial orchiectomy, while RPLND utilization has decreased. There was no significant difference in CSM between surveillance and active treatment groups, but RPLND demonstrated significantly lower CSM than CHT in active treatment. Our findings suggest that the usage of RPLND in patients with stage I TMGCT should be reconsidered.

RESUMO

Phage therapy is the application of bacterial viruses to control and, ideally, to eliminate problematic bacteria from patients. Usually employed are so-called strictly lytic phages, which upon adsorption of a bacterium should give rise to both bacterial death and bacterial lysis. This killing occurs with single-hit kinetics, resulting in relatively simple ways to mathematically model organismal-level, phage-bacterium interactions. Reviewed here are processes of phage therapy as viewed from these simpler mathematical perspectives, starting with phage dosing, continuing through phage adsorption of bacteria, and then considering the potential for phage numbers to be enhanced through in situ phage population growth. Overall, I suggest that a basic working knowledge of the underlying "simple maths" of phage therapy can be helpful toward making dosing decisions and predicting certain outcomes. This especially is during controlled in vitro experimentation but is relevant to thinking about in vivo applications as well.

RESUMO

OBJECTIVE: Young adult patients with cancer are a growing concern. By means of network analysis, this study aimed to explore the interplay between dignity-related distress and quality of life (QoL) in young adult patients with cancer when they undergo active treatments. METHODS: In this cross-sectional study, 309 young adults aged 18-39 and diagnosed with malignant tumors were recruited from an oncology center in China between September 2020 and August 2021. Participants completed the Patient Dignity Inventory and SF-36 questionnaires. Network analysis was applied to examine the network structure. RESULTS: Overall, the core facets of dignity-related distress were negatively related to QoL and its corresponding domains, either directly or indirectly. Developmental distress played a central role among estimated networks and strongly interplayed with most QoL domains, especially the mental domains. Symptom distress was the only facet consistently interplayed with the physical domains of QoL (i.e., physical function and bodily pain). The social aspects were also revealed in the association between limited social support and vitality. CONCLUSIONS: Early attention must be paid to guarantee the need of preserving dignity and enhancing QoL for young adult patients.

RESUMO

Recent evidence suggests that short-term obstructive sleep apnea (OSA) treatment could affect OSA pathogenesis such as ventilatory control. The aim of our present study was to identify the impact of long-term treatment on the change in pathogenesis and natural progression of OSA. In a longitudinal analysis of a non-obese cohort study, patients with OSA treated with either continuous positive airway pressure (CPAP) or an oral appliance (OA), interrupted their treatment for 1 week and underwent a polysomnography (PSG) off treatment that was compared with their initial PSG taken 5 years before treatment initiation. In all, 154 consecutive patients with OSA who were treated by CPAP using an auto-titrating continuous positive airway pressure device (CPAP-APAP) (n = 112), or by OA (n = 27) or were untreated (n = 15), PSG was performed twice with a median (range) follow-up of 93 (60-176) months. Multivariate logistic regression showed that reduction of body mass index (BMI) and good treatment adherence to be significant predictors of favourable OSA progression, as represented by an improved or unchanged apnea-hypopnea index (AHI) (odds ratios were 5.14 and 2.89, respectively). Amongst the patients with an unchanged BMI and good CPAP-APAP adherence (n = 55), the improvement in AHI was significantly associated with the decrease in supine non-rapid eye movement-AHI and mixed apnoea index/apnoea index, which are generally recognised to be determinants of ventilator instability. These findings suggest that not only weight but also treatment adherence are determinants in the natural progression of OSA severity.

RESUMO

BACKGROUND: KPC-K.pneumoniae bloodstream infection (KPC-KpBSI) mortality rate in patients with hematological malignancies is reported about 60%. The initial treatment active against KPC-K.pneumoniae is crucial for survival and KPC-K.pneumoniae rectal colonization usually precedes KPC-KpBSI. We evaluated the impact on KPC-KpBSI mortality of the preemptive use of antibiotics active against KPC-K.pneumoniae, as opposed to inactive or standard empiric antibiotics, for the empiric treatment of febrile neutropenia episodes in patients with hematological malignancy identified as KPC-K.pneumoniae intestinal carriers. METHODS: We compared the outcomes of KPC-KpBSIs occurring in high-risk hematological patients known to be colonized with KPC-K.pneumoniae, during two time periods: March2012-December2013 (Period 1, initial approach to KPC-K.pneumoniae spread) and January2017-October2018 (Period 2, full application of the preemptive strategy). The relative importance of the various prognostic factors that could influence death rates were assessed by forward stepwise logistic regression models. RESULTS: KPC-KpBSI-related mortality in hematological patients identified as KPC-K.pneumoniae carriers dropped from 50% in Period 1 to 6% in Period 2 (p < 0.01), from 58 to 9% in acute myeloid leukemia carriers(p < 0.01). KPC-KpBSIs developed in patients identified as KPC-K.pneumoniae carriers were initially treated with active therapy in 56% and 100% of cases in Period 1 and Period 2, respectively (p < 0.01), in particular with an active antibiotic combination in 39 and 94% of cases, respectively(p < 0.01). The 61% of KPC-KpBSI observed in Period 1 developed during inactive systemic antibiotic treatment (none in Period 2, p < 0.01), fatal in the 73% of cases. Overall, KPC-KpBSI-related mortality was 88% with no initial active treatment, 11.5% with at least one initial active antibiotic (p < 0.01), 9% with initial active combination. Only the initial active treatment resulted independently associated with survival. CONCLUSIONS: In high-risk hematological patients colonized by KPC-K.pneumoniae, the empiric treatment of febrile neutropenia active against KPC-K.pneumoniae reduced KPC-KpBSI-related mortality to 6% and prevented fatal KPC-KpBSI occurrence during inactive systemic antibiotic treatment.

RESUMO

A complete clearance of vulvar lichen sclerosus (VLS) is achieved in a minority of patients treated with a standard 12-week duration corticosteroid treatment. The aim of this pragmatic, retrospective, open label, comparative trial was to assess the effectiveness, in terms of complete clearance, of a 24-week treatment with mometasone furoate 0.1% ointment (MMF) and to compare it with a 12-week therapy. We included VLS patients treated with MMF administered for five consecutive days/week for 24 weeks (group A). The following were assessed: (a) clearance in Global Subjective Score (GSS), Global Objective Score (GOS) or both, (b) changes of these parameters and dyspareunia at treatment completion compared to baseline, (c) safety profile. All these assessments were compared with the same outcomes recorded among VLS patients who had previously undergone a 12-week MMF treatment (group B). Twenty-nine patients were included in group A and 32 in group B. The rates of patients who achieved the clearance of GSS, GOS or both parameters did not significantly differ between groups A and B. The groups did not differ in any of the effectiveness outcomes assessed. A 24-week duration corticosteroid treatment does not seem to provide significant therapeutic benefits in comparison with standard 12-week courses, especially considering the occurrence of complete clearance.

RESUMO

INTRODUCTION: Viral, bacterial, or fungal infections are suspected of triggering multiple sclerosis (MS) and promoting relapses of the disease and are likely to be promoted by immune-active treatments. This raises questions about the infectious workup and preventive treatment of these infections prior to their initiation. OBJECTIVES: To establish recommendations on infections and MS. Provide information to patients and healthcare professionals on the minimal infectious workup to be performed in an MS patient at diagnosis and prior to initiation of immuno-active therapy in MS. METHODS: The recommendation attempts to answer four main questions about infections and MS. The French Group for Recommendations in Multiple Sclerosis (France4MS) did a systematic review of articles from PubMed and universities databases (from January 1975 to June 2020), using the RAND/UCLA formalized consensus method. The RAND/UCLA method has been developed to synthesize the scientific literature and expert opinions on health care topics and was used for reaching a formal agreement. Twenty-three experts contributed to the detailed review and a group of 63 multidisciplinary health professionals validated the final version of 36 recommendations. RESULTS: It is recommended that MS patients undergo a minimal infectious workup, check their vaccination status at diagnosis, and repeat it during follow-up and before starting immunotherapy. Screening and preventive treatment of viral (group Herpes virus, HPV, JCV, HCV, HBV), bacterial (mycobacteria) and fungal (Cryptococcus) infections is recommended prior to the initiation of certain immuno-active MS therapies. DISCUSSION AND CONCLUSIONS: At diagnosis of MS and prior to the choice of therapeutic strategy, it is recommended to update the vaccination schedule of MS patients in reference to the HCSP vaccination schedule and the SFSEP recommendations. Before starting immunosuppressive treatment, it is recommended to inform patients of the risks of infections and to look for a constitutive or acquired immune deficiency. Health professionals and patients should be informed of the updated recommendations on infections and MS.

RESUMO

We report a bubble-propelled Janus gallium/zinc (Ga/Zn) micromotor with good biocompatibility and biodegradability for active target treatment of bacteria. The Janus Ga/Zn micromotors are fabricated by asymmetrically coating liquid metal Ga on Zn microparticles and display self-propulsion in simulated gastroenteric acid (pH 0.5) at a speed of up to 383 µm s-1 , propelled by hydrogen bubbles generated by the zinc-acid reaction. This motion of Ga/Zn micromotors is enhanced by the Ga-Zn galvanic effect. The GaIII cations produced from the degradation of Ga/Zn micromotors serve as a built-in antibiotic agent. The movement improves the diffusion of GaIII and results in a significant increase of the antibacterial efficiency against H. pylori, compared with passive Ga microparticles. Such Ga/Zn micromotors combine the self-propulsion, good biocompatibility and biodegradability, and Ga-based antibacterial properties, providing a proof of concept for the active treatment of bacterial infections.

RESUMO

The additional benefits in the analysis of crossover designs with two active treatments and a placebo motivated us to study these kinds of designs. These designs have been studied through a computer search algorithm, called 5M balanced algorithm, in two to four periods for different number of units, which resulted in optimal and/or efficient crossover designs. The new two periods crossover designs having two active treatments and a placebo, enables the estimation of treatment contrasts, unlike the classic two treatments two periods crossover which fails to estimate the treatment contrasts under self and mixed carryover model. The crossover designs having three or four periods in two active treatments and a placebo, estimate treatment contrasts more efficiently under self and mixed carryover model than the usual two treatments crossover designs. An exhaustive list of optimal and/or efficient crossover designs has been provided for designs in two periods having 6-21 subjects, three periods having 3-20 subjects and four periods having 3-14 subjects. In this list, 35 new designs are optimal for one of the established carryover models and 26 new designs are optimal and/or efficient to all four plausible carryover models.

RESUMO

BACKGROUND: The majority of patients with acute myeloid leukemia (AML) are aged >65 years at the time of diagnosis and are not actively treated. The objective of the current study was to determine the prevalence, temporal trends, and factors associated with no active treatment (NAT) among older patients with AML in the United States. METHODS: A retrospective analysis was performed of Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 14,089 patients with AML residing in the United States who were diagnosed with AML at age ≥66 years during 2001 through 2013. NAT was defined as not receiving any chemotherapy, including hypomethylating agents. Multivariable logistic regression models were used to analyze sociodemographic, clinical, and provider characteristics associated with NAT. RESULTS: The percentage of patients with NAT decreased over time from 59.7% among patients diagnosed in 2001 to 42.8% among those diagnosed in 2013. The median overall survival for the entire cohort was 82 days from the time of diagnosis. Patients treated with NAT had worse survival compared with those receiving active treatment. Variables found to be associated with higher odds of NAT included older age, certain sociodemographic characteristics (household income within the lowest quartile, residence outside the Northeast region of the United States, and being unmarried), and clinical factors (≥3 comorbidities, the presence of mental disorders, recent hospitalization, and disability). CONCLUSIONS: Greater than one-half of older patients with AML residing in the United States do not receive any active leukemia-directed therapy despite the availability of lower intensity therapies such as hypomethylating agents. Lack of active therapy receipt is associated with inferior survival. Identifying predictors of NAT might improve the quality of care and survival in this patient population, especially as novel therapeutic options with lower toxicity are becoming available.

RESUMO

PURPOSE: The purpose of this study was to explore the acceptability, applicability, and understandability of a promising advance care planning (ACP) web-based resource for use with oncology patients, and determine whether revisions to the website would be necessary before implementation into oncology care. The resource is called PREPARE ( www.prepareforyourcare.org ) and it had not been tested for use within oncology, but had previously been shown to influence the readiness of older, community-dwelling adults to engage in ACP behaviors. METHODS: This qualitative descriptive study included participants receiving cancer medications and one participant on watchful waiting post-chemotherapy (n = 21). Data were collected via cognitive interviewing, followed by a brief semi-structured interview to gather a meaningful account of the participants' experience with PREPARE. Content analysis resulted in a comprehensive summary of what participants liked and did not like about the resource, as well as suggestions for change. RESULTS: Overall, participants agreed PREPARE was acceptable, applicable, and understandable for cancer patients. A small number of participants had difficulty with the life-limiting language found within the website and this requires follow-up to determine whether the language causes distress or disengagement from ACP. These findings extend our understanding of barriers to engagement in ACP that appear unique to cancer patients receiving active treatment. CONCLUSIONS: Results indicated that PREPARE is a reflective, capacity-building ACP resource that was acceptable, applicable, and understandable for use in oncology. These findings offer direction for both research and practice.

RESUMO

BACKGROUND: Of the more than 1.1 million men diagnosed worldwide annually with prostate cancer, the majority have indolent tumors. Distinguishing between aggressive and indolent cancer is an important clinical challenge. The current approaches for assessing tumor aggressiveness are recognized as insufficient. A validated protein-based assay has been shown to predict tumor aggressiveness from prostate biopsy. The main objective of this study was to measure the clinical utility of this new assay in the management of early-stage prostate cancer. METHODS: One hundred twenty nine board-certified urologists were asked to participate in a randomized, two-arm experiment. We collected data over 2 rounds using simulated clinical cases administered via an online platform. The cases were all newly diagnosed Gleason 3 + 3 or 3 + 4 prostate camcer patients. Urologists in the intervention arm received a 15-min webinar on this protein-based assay and given assay test results for their simulated patients in round 2. Each case had a preferred recommendation of either active surveillance or active treatment. The measured outcome was rate of preferred recommendation, defined as urologists who recommended the proper treatment course. Analyses were done using difference-in-difference estimations. RESULTS: Using multinomial logistical regression, urologists who were given the assay results were significantly more likely to choose the preferred recommendation (active surveillance or active treatment) compared to controls (p = 0.004). These urologists were also significantly more likely to involve their patients in the treatment decision compared to controls (p = 0.001). CONCLUSIONS: By providing additional information to inform the physician's treatment plan, a protein-based assay shows demonstrable clinical utility confirmed through a rigorous randomized controlled study design and regression analyses to test for effects.

RESUMO

OBJECTIVES: To evaluate clinical factors associated with tumour upgrading (UPG) in low-intermediate risk patients who progressed while under active surveillance (AS) and underwent delayed radical prostatectomy. MATERIAL AND METHODS: The evaluated factors included prostate specific antigen (PSA), prostate volume, PSA density and number of biopsy positive cores (BPC). Multivariate logistic regression by the forward step Wald procedure was used. RESULTS: The study evaluated 24 patients who had UPG in 13 cases (54.2%). Independent factors associated with tumour UPG included PSA (OR 2.1; p = 0.047) and BPC (OR 2; p = 0.042). CONCLUSIONS: Clinical factors associated with UPG were identified in patients who were under AS for with low-intermediate risk disease. Preoperative PSA levels and number of BPC were independent factors associated with UPG in a contemporary cohort of patients who progressed under AS and underwent delayed active treatment.

RESUMO

The transition from the end of active treatment to survivorship holds many challenges for women with endometrial cancer (WEC) and for the organization of health services. The feasibility and acceptability of implementing an individualized survivorship care plan (ISCP) at the end of treatment are documented as potential solutions. The utility of an ISCP on three indicators (SUNS, FCRI, and HeiQ) was pre-tested by comparing two groups of WEC (control and exposed to the ISCP). The WEC exposed to the ISCP had fewer needs, a lesser intensity of fear of cancer recurrence, and better health-related empowerment skills three months after the end of treatment, as compared to the control group. Obstacles of time, resources, and organization were raised. BACKGROUND: The transition from the end of active treatment to cancer survivorship is a time of imbalance and turbulence for women with endometrial cancer (WEC). The transition to survivorship continues to be uncoordinated and the need for information about the side effects to watch for and the health risks is unmet. The implementation of an individualized survivorship care plan (ISCP) is suggested as an information and communication tool that could be a solution for facilitating the transition from the end of treatment to the beginning of survivorship. RESEARCH OBJECTIVE AND METHOD: To assess and document the feasibility and acceptability of implementing an ISCP, qualitative data were gathered from WEC, oncology nurse navigators (ONN), and family doctors. A pre-experimental research design with a non-equivalent control group, an end of treatment (T0), and a three-month follow-up (T1) allowed us to pre-test its utility according to three indicators: (1) overall needs (SUNS); (2) fear of cancer recurrence (FCRI); and (3) empowerment (HeiQ) according to exposure to ISCP (control versus exposed) and to the time of measurement in the transition period (T0 versus T1). RESULTS: The sample was made up of 18 WEC for the group exposed to the ISCP and 13 WEC for the control group, 12 general practitioners, and two ONN. After ONN training, the ISCP completion time varied between 60 and 75 minutes, and the meeting for providing the ISCP lasted 45-60 minutes. The WEC supported the idea that meetings with the ONN and the ISCP were useful in meeting their needs for information and support. The family doctors supported its relevancy in favouring follow-up and better subsequent healthcare management, as well as in reassuring patients and avoiding a sense of abandonment at the end of treatment. Comparing the group exposed to the ISCP versus the control group, fewer reported needs can be observed: information: 35% versus 74%, p = .030; professional and financial: 6% versus 19%, p = .057; access and continuity: 9% versus 25%, p = .078; support: 18% versus 50%, p = .007, emotional: 13% versus 28%, p = .044). Moreover, at T1, empowerment according to the skill and technique acquisition sub-scale shows a higher trend (M = 75.00 (10.21) versus M = 64.06 (10.67), p = .097). The level of fear of recurrence remains above the clinically significant score of 13 for both groups at the two times of measurement. DISCUSSION: The ISCP is an informational tool that seeks to facilitate care-related communication and coordination between specialized and primary care. It is intended to facilitate the transition from the end of treatment to survivorship and survivors' commitment to health-related empowerment behaviours. The feasibility and utility of implementing an ISCP are supported if additional professional, organizational, and financial resources are specified and mobilized.

RESUMO

Many cancer survivors finish their treatment without knowing the associated health risks and few are prepared to handle their health needs in the survivorship phase. Moreover, practical guides for follow- up care are not available and survivors' psychological and social needs often go unassessed. In this article, we propose the development and implementation of an individualized follow-up care plan (IFCP) after active treatment for women with endometrial cancers (WEC) to meet their needs for information and to facilitate the transition to the survivorship phase. BACKGROUND: The after-treatment phase is a distinct phase that is still neglected in the oncological continuum of care. It is the transition between two phases in the care trajectory-treatment and survivorship-that gives rise to many challenges for survivors, care providers and the healthcare system alike. RESEARCH GOAL: Aiming to facilitate the transition between the end of active treatment and the cancer survivorship phases, we pursued two objectives: 1) Develop an individualized follow-up care plan (IFCP) based on both the literature and the perspective of WEC, healthcare professionals involved with the target clientele and oncology outreach managers, and 2) Have this IFCP validated by an interdisciplinary team. METHODOLOGY: For the first objective, WEC-related needs at the end of active treatment (immediate end, three months and six months), as well as the perceptions of health professionals and oncology outreach managers were gathered by interview and group discussion on the benefit of an IFCP, its content and desired format. A content analysis of the interview data was performed using the Miles and Huberman approach (2003). For the second objective, an iterative consultation process with health professionals allowed for validation by consensus. These two objectives are the first qualitative phase of a mixed-methods sequential exploratory design that will make the development of an IFCP possible. In the second phase, we conducted a feasibility study of the implementation of the IFCP during the end of active treatment transition to cancer survivorship transition. This will be the subject of a second article. RESULTS: The interviews (n=47) revealed WECs' lack of preparation for the transition from the end of active treatment to the cancer survivorship. The following needs were specified: information (80%), emotional support, particularly to overcome their fear of recurrence (75%), the management of physical symptoms (45%), and support for adapting to change (45%). The data gathered from healthcare professionals and outreach managers support the utility of an IFCP in meeting these needs. The iterative validation process by the interdisciplinary team made consensus on the format and content possible. The final version of the IFCP is seen as a tool for information and communication in the survivorship phase. Some obstacles to its transfer to clinical practice are reported. CONCLUSION: This study presents the entire process that led to the development of an IFCP that integrates both the needs of endometrial cancer survivors and the opinions of healthcare professionals and the oncology outreach managers organizing this care. Indications on how the IFCP could be implemented within this organization are also formulated.

RESUMO

BACKGROUND: The current review revisits the article entitled: "Active Ingredients: How and Why Evidence-Based Alcohol Behavioral Treatment Interventions Work" published in Alcoholism: Clinical and Experimental Research. This work summarized proceedings from a 2004 Symposium of the same name that was held at the Annual Meeting of the Research Society on Alcoholism (RSA). A decade has passed, which provides occasion for an evaluation of progress. In 2014, an RSA symposium titled Active Treatment Ingredients and Client Mechanisms of Change in Behavioral Treatments for Alcohol Use Disorders: Progress 10 Years Later did just that. METHODS: The current review revisits state-of-the-art research on the 3 treatments examined 10 years ago: cognitive behavioral therapy, alcohol behavior couples therapy, and 12-step facilitation. Because of its empirically validated effectiveness and robust research agenda on the study of process outcome, motivational interviewing has been selected as the fourth treatment modality to be discussed. For each of these 4 treatments, the reviewers provide a critical assessment of current theory and research with a special emphasis on key recommendations for the future. RESULTS: Noteworthy progress has been made in identifying active ingredients of treatments and mechanisms of behavior change in these 4 behavioral interventions for alcohol and other drug use disorders. Not only have we established some of the mechanisms through which these evidence-based treatments work, but we have also uncovered some of the limitations in our existing frameworks and methods. CONCLUSIONS: Further progress in this area will require a broader view with respect to conceptual frameworks, analytic methods, and measurement instrumentation.

RESUMO

Owing to the dense extracellular matrix and high interstitial fluid pressure in the tumor microenvironment, methods which enhance the permeation and retention of nano drugs into liver tumors remain unsatisfactory for successful tumor treatment. We designed a near-infrared (NIR)- and ultrasound (US)-triggered Pt/Pd-engineered "cluster bomb" (Pt/Pd-CB) which actively penetrates liver cancer cell membranes and achieves photothermal and sonodynamic therapy (SDT). The physical forces generated by the fast expansion and collapse of perfluoropentane nanodroplets eject "sub bombs" (Pt/Pd nanoalloys) into liver cancer cells upon activation by NIR and US. Pt/Pd nanoalloys can then convert H2O2 into O2 to alleviate hypoxia and boost SDT efficiency while exhibiting a highly efficient photothermal response under NIR irradiation. Our findings might especially be promising for the treatment of solid tumors.

RESUMO

OBJECTIVES: This study aimed to identify the level of spirituality, faith and meaning, and quality of life (QOL) among Muslim advanced cancer patients undergoing active treatment and to enhance the understanding of the relationships among clinical and socio-demographic factors, spirituality, and QOL of patients in the Gaza Strip. METHODS: A secondary analysis was conducted on a convenience sample of 298 advanced cancer patients. The Arabic versions of the Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) and the Functional Assessment of Cancer Therapy-General (FACT-G) were used for data collection. Descriptive statistics and generalized linear regression were utilized for data analysis, performed using SPSS 25.0. RESULTS: Participants reported high spirituality well-being scores (Mean = 31.25, SD = 6.25) and relatively high scores on the subscales of meaning/peace (Mean = 19.15, SD = 4.11) and faith (Mean = 12.03, SD = 3.50). Most patients indicated that their faith and spiritual beliefs increased due to their illness. Furthermore, a significant positive relationship was found between spirituality (including its subscales of faith and meaning in life) and QOL. Despite the generally high level of spirituality, special attention should be paid to patients with lung, bladder, and thyroid cancer, lower education levels, and higher cancer grades. CONCLUSIONS: The Gazan Muslim patients with advanced cancer exhibit high levels of spirituality and faith. We acknowledged that spiritual well-being is a protective factor for QOL. The strong positive correlation between spirituality and QOL emphasizes the need to integrate spiritual care into cancer care. IMPLICATIONS FOR NURSING PRACTICE: It is imperative to incorporate spirituality into health practice and the daily routines of cancer treatment for patients whose spirituality is an important aspect of their identities. The incorporation of spirituality can contribute to the improvement of the quality of patients' life and quality of cancer care.
