Solvent Exchange Dynamics in M2(dobdc): An Interplay among Binding Strength, Exchange Kinetics, and Cooperativity.

Solvent exchange is a crucial step in ensuring the complete activation of metal-organic frameworks (MOFs); however, the conditions for solvent exchange vary among MOFs, even within the isostructural variants. This study examines the factors contributing to solvent exchange by investigating the isostructural M2(dobdc) (M═Mg, Co, Zn) series. Common solvents N,N-dimethylformamide (DMF), ethanol (EtOH), and methanol (MeOH) are employed to assess the solvent exchange at coordinatively unsaturated sites (CUS) of M2(dobdc). By monitoring both solvents released from the MOF during solvent exchange and the coordination environment of metals within the MOF, a picture is constructed of exchange rates during early stages of solvent exchange as well as expulsion of the last traces of bound solvents. This differentiation is achieved by a combination of bulk monitoring of solvent phase composition and microscopic application of Raman spectroscopy on the single-crystal level. The kinetics of solvent replacement is revealed to have a substantial contribution from cooperativity; this phenomenon is observed in both the forward and reverse directions. Thermogravimetric analysis coupled with IR spectroscopy and density functional theory (DFT) calculations are employed to elucidate the relationship between solvent exchange rates and solvent binding energy. The solvent exchange rates are determined by the kinetic barriers of solvent exchange that do not follow the order of the solvent binding affinity. This work contributes to understanding the solvent exchange of MOFs by examining the interplay among the binding strength, exchange kinetics, and cooperativity. It further provides valuable insights for scrutinizing MOF activation protocols.

Perspectives of health care providers referring patients to a newly implemented sexual health program in a Canadian cancer center.

PURPOSE: Screening and discussion about sexual health concerns within cancer care are frequently impeded by lack of access to sexual health resources and lack of fluency with sexual health topics. To address this, a multi-disciplinary sexual health program was developed and piloted in a Canadian tertiary cancer center. The aim of this study was to assess referring health care providers' perspectives on the newly implemented oncology sexual health program. METHODS: A brief online survey was administered system-wide to cancer care providers to query their perceptions of the pilot multidisciplinary sexual health program, the Oncology and Sexuality, Intimacy and Survivorship (OASIS) program. RESULTS: According to survey results, the OASIS program was perceived by health care providers as valuable, helpful for patients, and important for addressing gaps in clinical care. Additional comments indicated an ongoing need for increased access to information about the program and referral procedures. CONCLUSION: Survey results highlight the need for consistent program dissemination efforts to equip health care providers with accessible patient education materials and easily implemented referral procedures. Importantly, providers indicated that they were more likely to raise the topic of sexuality with patients because they had somewhere to refer patients who had sexual concerns. Overall, findings inform efforts to implement sexual health programming within cancer care institutions.

The Oncology and Sexuality, Intimacy, and Survivorship Program Model: An Integrated, Multi-disciplinary Model of Sexual Health Care within Oncology.

Cancer-related sexual dysfunction is documented as one of the most distressing and long-lasting survivorship concerns of cancer patients. Canadian cancer patients routinely report sexuality concerns and difficulty getting help. In response to this gap in care, clinical practice guidelines were recently published in the Journal of Clinical Oncology. A sweeping trend is the creation of specialized clinics for patients' sexual health concerns. However, this much-needed attempt to address this service gap can be difficult to sustain without addressing the cancer care system from a broader perspective. Herein, we describe the implementation of a tiered systemic model of cancer-related sexual health programming in a tertiary cancer center. This program follows the Permission, Limited Information, Specific Suggestions, Intensive Therapy (PLISSIT) model, used previously for guiding individual practitioners. Visually, the model resembles a pyramid. The top 2 levels, corresponding to Intensive Therapy and Specific Suggestions, are comprised of group-based interventions for common cancer-related sexual concerns and a multi-disciplinary clinic for patients with complex concerns. The bottom 2 levels, corresponding to Permission and Limited Information, consist of patient education and provider education and consultation services. We describe lessons learned during the development and implementation of this program, including the necessity for group-based services to prevent inundation of referrals to the specialized clinic, and the observation that creating specialized resources also increased the likelihood that providers would inquire about patients' sexual concerns. Such lessons suggest that successful sexual health programming requires services from a systemic approach to increase sustainability.

Patient interest in the Lowdown on Down There: attendance at a vulvovaginal and sexual health workshop post-cancer treatment.

PURPOSE: Sexual difficulties and vulvovaginal changes are common for women undergoing, and following, cancer treatments. These changes have significant impacts on quality of life and significant relationships. The current study aimed to (1) evaluate women's interest and attendance in a group-based educational workshop to address changes in vulvovaginal health and sexuality after cancer, and (2) describe participant characteristics and presenting concerns. METHODS: Two hundred eighteen women with a history of cancer expressed interest in receiving information about the workshop and completed phone screening. Interested women (n = 156) completed an online questionnaire package examining vulvovaginal health and sexual function prior to attending the workshop. RESULTS: Approximately 75% of the women who completed screening attended the workshop. Clinically significant sexual distress was reported by 91% of participants, and 97% of sexually active participants exceeded the threshold for sexual dysfunction (per FSFI). Women within 1-2 years of diagnosis tended to report less sexual distress, less severe vulvovaginal symptoms, and less impact from these symptoms compared to women farther out from diagnosis. While the majority of women reported vaginal dryness and pain during intercourse, only a minority reported engaging in health promotion strategies sufficient to expect symptom improvement. CONCLUSIONS: The current study suggests that group-based educational workshops for vulvovaginal and sexual concerns are utilized by patients and should be offered to women well into disease survivorship. Workshops targeting vulvovaginal symptoms and sexual concerns may be a cost-effective method of reducing sexual distress and improving patients' sexual function and quality of life.

Quality improvement in sexual health care for oncology patients: a Canadian multidisciplinary clinic experience.

PURPOSE: With the goal of improving the quality of sexual health care provision at our tertiary cancer centre, we developed, implemented, and assessed a multidisciplinary sexuality in an oncology program, to identify patient needs and apply interventions that could be effective in a broader oncology care context. METHODS: The establishment of our institution's first oncology-focused sexual health program is described within a quality improvement framework. A complementary retrospective chart review was performed to evaluate clinicodemographic data, including responses to validated sexual health questionnaires, from a 2-year clinical pilot. RESULTS: A sexual health program was introduced for cancer patients identified by health care providers or self-referred, receiving 130 referrals and conducting 64 consultation and 75 follow-up visits within a 2-year pilot period. Patients attending the program were 75% female, of mean age 52 years, and had most often breast (33%) or hematologic (30%) malignancies. Most (84%) had completed curative-intent treatment, with no evidence of disease, with 34% on ongoing endocrine therapy. The most frequent reasons for referral were sexual pain (38%), decreased libido (35%), and vaginal dryness (35% of females). All female patients demonstrated sexual dysfunction on the Female Sexual Function Index, and 80% of male patients demonstrated moderate to severe erectile dysfunction on the Sexual Health Inventory for Men. Patients waited a median of 63 days (SD 107, range 3-516) from referral to consultation, suggesting that demand for multidisciplinary sexual health care overwhelmed existing resources. CONCLUSIONS: We have demonstrated unmet sexual health needs across a diverse oncology patient population and have presented a framework for addressing these issues, highlighting the challenges encountered and proposing improvements. Insights emerging from a quality improvement perspective included the role of group-based sexual health support to improve accessibility and the need for staff education to encourage proactive intervention before referral for specialized care is needed.

Assessing the utility of a distress screening tool at capturing sexual concerns in a gyne-oncology follow-up clinic.

PURPOSE: Communication and assessment of sexual health within cancer care is poor despite high rates of sexual dysfunction in cancer survivors. Screening for distress programs have been implemented, as a standardized part of cancer care across Canada, with the aim of increasing identification and improving access to support. Alberta Health Services uses a general distress screening form, containing the Canadian Problem Checklist, which includes a list of possible problems, one of which is "intimacy/sexuality." Theoretically, the discreet nature of the screening for distress form may reduce patient discomfort in disclosing sexual concerns verbally, and therefore help health care providers identify patients requiring intervention. This study aims to determine the adequacy of this distress screening tool in identifying gynecological cancer patients who have an intimacy/sexuality concern. METHODS: A chart review was conducted on all follow-up visits in a gyne-oncology clinic over 1 year. Each patient's chart was reviewed to determine the prevalence of the distress screening form completion, prevalence of the "intimacy/sexuality" item being checked, and documentation of actions taken to address any reported intimacy/sexuality problems. RESULTS: Seven hundred thirty patient visits were recorded during this period with completed distress screening forms found on 79.0% (n = 577) of charts. Only 6% of the patients indicated an intimacy/sexuality concern on this form. Of those, only one third had documentation that their problem was addressed. CONCLUSIONS: These results call into question the utility of the intimacy/sexuality item on the Canadian Problem Checklist to identify gynecological cancer patients who have sexual concerns. Furthermore, even among those patients who indicated concerns, there is evidence that their problems are rarely addressed. Providers need to directly inquire with patients about their sexual health.

A comprehensive review of sexual health concerns after cancer treatment and the biopsychosocial treatment options available to female patients.

The repercussions of cancer diagnosis and treatment profoundly impact the sexual wellbeing of women prior to, during, and following cancer treatment. Sexual health concerns are often under-addressed within clinical and research settings, and information tends to be limited to women with breast or gynecological cancers. In this narrative literature review, the authors critically evaluate research published between 1990 and 2016, pertaining to sexual health concerns of women diagnosed with cancer, of any type or stage, and to the psychosocial and biomedical interventions that currently exist for the treatment of sexual health-related side-effects (e.g. vaginal dryness, dyspareunia and vulvo-vaginal atrophy). The findings of 109 published articles are discussed and summarised according to four central themes: how cancer affects female sexual wellbeing; physical impacts of cancer diagnosis and treatment; emotional impacts of cancer diagnosis and treatment; and interventions for sexual dysfunction. Suggestions to enhance research and clinical practice in relation to the sexual health concerns of women following cancer treatments are also presented. Concerns pertaining to women's sexual health are diverse, multiple, and pervade all types and stages of cancer. Several evidence-based psychosocial and biomedical interventions exist to help women manage physical and psychosocial ramifications of cancer diagnosis and treatment.

Intimacy after prostate cancer: A brief couples' workshop is associated with improvements in relationship satisfaction.

OBJECTIVE: Prostate cancer (PCa) treatments often leave men with erectile dysfunction (ED). Even when ED treatments are effective in restoring men's ability to have an erection sufficient for intercourse, couples continue to struggle sexually. Effective treatments to help couples recover sexually are needed. METHOD: PCa patients and partners (N = 59 couples) attending a one-time couples' intimacy workshop, participated in an evaluation. The workshop, offered eight times over a 2-year period, emphasized a couples-based approach to treatment that enhances direct communication about sexuality and implementation of sexual recovery strategies that are consistent with the couple's values. Couples completed pre and post questionnaires (at baseline and 2 months later) assessing the primary outcome of relationship adjustment (Revised Dyadic Adjustment Scale) and secondary outcome of sexual function (Sexual Function Questionnaire). T-tests were employed to examine pre-post changes in scores. A small qualitative sub-study was conducted on the use of a Commitment to Change goal-setting exercise, completed during the workshop. RESULTS: Results provide insight into the specific nature of improvements. Patients and partners showed improvements in relationship satisfaction. Improvements with small-to-medium effect sizes were observed for patients and partners sexual function; however, after adjusting for multiple comparisons, these changes were no longer statistically significant. The specific goals set by couples, and their achievement status, are presented. CONCLUSIONS: The workshop offers a comprehensive, one-session intervention to help couples implement a treatment plan to promote sexual recovery after PCa treatment. Given the observed improvements, progression to a randomized control trial is warranted. Copyright © 2016 John Wiley & Sons, Ltd.

Reporting instructions significantly impact false positive rates when reading chest radiographs.

OBJECTIVES: To determine the impact of specific reporting tasks on the performance of radiologists when reading chest radiographs. METHODS: Ten experienced radiologists read a set of 40 postero-anterior (PA) chest radiographs: 21 nodule free and 19 with a proven solitary nodule. There were two reporting conditions: an unframed task (UFT) to report any abnormality and a framed task (FT) reporting only lung nodule/s. Jackknife free-response operating characteristic (JAFROC) figure of merit (FOM), specificity, location sensitivity and number of true positive (TP), false positive (FP), true negative (TN) and false negative (FN) decisions were used for analysis. RESULTS: JAFROC FOM for tasks showed a significant reduction in performance for framed tasks (P = 0.006) and an associated decrease in specificity (P = 0.011) but no alteration to the location sensitivity score. There was a significant increase in number of FP decisions made during framed versus unframed tasks for nodule-containing (P = 0.005) and nodule-free (P = 0.011) chest radiographs. No significant differences in TP were recorded. CONCLUSIONS: Radiologists report more FP decisions when given specific reporting instructions to search for nodules on chest radiographs. The relevance of clinical history supplied to radiologists is called into question and may induce a negative effect. KEY POINTS: • Framed reporting tasks increases false positive rates when searching for pulmonary nodules • False positive results were observed in both nodule-containing and nodule-free cases • Radiologist's decision-making may be influenced by clinical history in thoracic imaging.

Psychological effects of androgen-deprivation therapy on men with prostate cancer and their partners.

The clinical benefits of androgen-deprivation therapy (ADT) for men with prostate cancer (PC) have been well documented and include living free from the symptoms of metastases for longer periods and improved quality of life. However, ADT comes with a host of its own serious side effects. There is considerable evidence of the adverse cardiovascular, metabolic, and musculoskeletal effects of ADT. Far less has been written about the psychological effects of ADT. This review highlights several adverse psychological effects of ADT. The authors provide evidence for the effect of ADT on men's sexual function, their partner, and their sexual relationship. Evidence of increased emotional lability and depressed mood in men who receive ADT is also presented, and the risk of depression in the patient's partner is discussed. The evidence for adverse cognitive effects with ADT is still emerging but suggests that ADT is associated with impairment in multiple cognitive domains. Finally, the available literature is reviewed on interventions to mitigate the psychological effects of ADT. Across the array of adverse effects, physical exercise appears to have the greatest potential to address the psychological effects of ADT both in men who are receiving ADT and in their partners.

What do Canadian uro-oncologists believe patients should know about androgen deprivation therapy?

INTRODUCTION: Patients prescribed luteinizing hormone-releasing hormone agonists for androgen deprivation therapy (ADT) have significant misconceptions about treatment side effects and how to manage them. We surveyed a subset of Canadian physicians about what they think is important information to tell patients starting on ADT to determine the degree to which there is consensus of opinion. METHOD: A questionnaire about ADT side effects and management strategies was distributed to physicians-urologists, radiation oncologists, and medical oncologists - actively practicing within cancer and urology centers in the Canadian provinces of British Columbia, Alberta, Ontario, and the Maritime Provinces. RESULT: A total of 75 physicians filled out the survey. Physicians agreed that osteoporosis, erectile dysfunction, hot flashes, loss of libido, and loss of muscle mass were drug responses that were essential or important to warn patients about. However, for six commonly reported side effects (i.e. depression, diabetes, elevated cholesterol, anemia, delayed or absent orgasm, and genital shrinkage), physicians showed great variance, with less than 60% agreeing on whether to discuss these topics or not. CONCLUSION: There is little consensus among physicians regarding what to tell patients when prescribing this treatment. The lack of agreement among physicians may partially explain the lack of awareness of ADT side effects by patients and partners. The current findings may help guide strategies for the design, evaluation, and implementation of educational interventions for both physicians and patients that will better prepare patients to recognize, adapt to, and overcome ADT side effects.

Kidney stone growth through the lens of Raman mapping.

Bulk composition of kidney stones, often analyzed with infrared spectroscopy, plays an essential role in determining the course of treatment for kidney stone disease. Though bulk analysis of kidney stones can hint at the general causes of stone formation, it is necessary to understand kidney stone microstructure to further advance potential treatments that rely on in vivo dissolution of stones rather than surgery. The utility of Raman microscopy is demonstrated for the purpose of studying kidney stone microstructure with chemical maps at ≤ 1 µm scales collected for calcium oxalate, calcium phosphate, uric acid, and struvite stones. Observed microstructures are discussed with respect to kidney stone growth and dissolution with emphasis placed on < 5 µm features that would be difficult to identify using alternative techniques including micro computed tomography. These features include thin concentric rings of calcium oxalate monohydrate within uric acid stones and increased frequency of calcium oxalate crystals within regions of elongated crystal growth in a brushite stone. We relate these observations to potential concerns of clinical significance including dissolution of uric acid by raising urine pH and the higher rates of brushite stone recurrence compared to other non-infectious kidney stones.

Enhancing care: evaluating the impact of True North Sexual Health and Rehabilitation eTraining for healthcare providers working with prostate cancer patients and partners.

Background: Educational programs that enhance healthcare providers' competence in managing the care of patients with sexual dysfunction following prostate cancer treatments are needed to facilitate comprehensive sexual health treatments for patients and their partners. Aim: In this study we evaluated the impact of a real-world online sexual health educational intervention called the True North Sexual Health and Rehabilitation eTraining Program. This program is designed to increase healthcare providers' knowledge and self-efficacy in providing sexual healthcare to prostate cancer patients and their partners. Methods: Healthcare providers were invited to join a 12-week virtual training program. Participants completed precourse surveys (n = 89), retrospective prepost surveys (n = 58), and a 3-month follow-up survey (subset n = 18) to assess retention of relevant outcomes. Additionally, a course satisfaction survey was administered to participants (n = 57) at the end of the course. Outcomes: The main outcomes focused on participants' perceived knowledge and self-efficacy in conducting assessments and providing interventions for various relevant physical, functional, psychological, and relational domains of sexual dysfunction in prostate cancer patients and their partners. Results: According to the retrospective analysis of post-then-pre-survey results, graduates perceived that their knowledge of and self-efficacy in providing sexual health counseling improved after completing the course. The 3-month follow-up survey indicated that the course graduate self-efficacy remained high 3 months after the course. Furthermore, the satisfaction survey indicated that a vast majority (98.2%) of participants were satisfied with the educational intervention. Clinical Implications: This real-world sexual health educational intervention can increase self-efficacy and knowledge in healthcare providers who are supporting prostate cancer patients dealing with sexual dysfunction. Strengths and Limitations: The use of a retrospective post-then-pre-survey helped to mitigate response shift bias while minimizing data gaps. However, it is important to note that this investigation was not a traditional research study and lacked a control group, thus limiting causal attributions. Conclusion: The True North Sexual Health and Rehabilitation eTraining program acts as an accessible and effective resource for healthcare providers seeking specialized training in providing sexual healthcare for prostate cancer patients and their partners.

A Non-Randomized Comparison of Online and In-Person Formats of the Canadian Androgen Deprivation Therapy Educational Program: Impacts on Side Effects, Bother, and Self-Efficacy.

Although Androgen Deprivation Therapy (ADT) is effective in controlling prostate cancer (PCa) and increasing survival, it is associated with a myriad of side effects that cause significant morbidity. Previous research has shown that PCa patients starting on ADT are neither fully informed nor well-equipped to manage the breadth of ADT's side effects. The ADT Educational Program (a 1.5 h interactive class plus a book) was developed as an evidence-based resource for patients dealing with ADT. Our aim here was to compare the efficacy of an online version of the class with a previously assessed in-person version of the class. Using mixed MANOVAs within a non-randomized comparison design, we assessed: (1) changes in patients' experiences of self-efficacy to manage and bother associated with side effects approximately 10 weeks after attending a class, and (2) potential differences in these variables between online and in-person class formats. Side effect bother decreased from pre- to post-class but did not differ between in-person (n = 94) and online (n = 137) class cohorts. While self-efficacy to manage side effects was slightly higher post-class in both cohorts, the increase was not statistically significant. Average self-efficacy ratings were significantly higher among in-person versus online class participants (p < 0.05; ηp2 = 0.128). Both online and in-person classes are associated with a significant reduction in the severity of side effect bother reported by PCa patients, suggesting non-inferiority of online versus in-person formats. Online classes offer greater accessibility to the program for patients outside the reach of in-person classes, increasing the availability of the program to more PCa patients and family members across Canada.

A brief couples' workshop for improving sexual experiences after prostate cancer treatment: a feasibility study.

PURPOSE: The most difficult survivorship issue reported by prostate cancer patients is the dramatic changes in their sexual relationships. The purpose of this study was to investigate the feasibility of a workshop designed to improve patients' and partners' sexual relationships. METHOD: Participants attended one 3.5-h workshop. A total of three separate workshops were held over a 12-month period. Patients and partners complete the Sexual Functioning Questionnaire (SFQ) prior, 2 months following, and if couples registered early enough, 2 months before the workshop. Change scores were calculated. RESULTS: Over the three workshops, 77 participants attended. All targets were met for feasibility and acceptability. Patients and partners both demonstrated significant gains on the medical impact subscale of the SFQ, and partners also demonstrated significant gains in sexual interest, problems, and total sexual function. CONCLUSIONS: The results suggest that attending one 3.5-h workshop that is offered every 4 months is feasible and acceptable to patients and their partners. Furthermore, the SFQ proves to be a sensitive assessment instrument of sexual function for patients and their partners.

Sexual values as the key to maintaining satisfying sex after prostate cancer treatment: the physical pleasure-relational intimacy model of sexual motivation.

Sexual dysfunction is the most significant long lasting effect of prostate cancer (PrCa) treatment. Despite the many medical treatments for erectile dysfunction, many couples report that they are dissatisfied with their sexual relationship and eventually cease sexual relations altogether. We sought to understand what distinguishes successful couples from those who are not successful in adjusting to changes in sexual function subsequent to PrCa treatment. Ten couples who maintained satisfying sexual intimacy after PrCa treatment and seven couples that did not were interviewed conjointly and individually. Interviews were transcribed and analyzed using grounded theory methodology. The theory that resulted suggests that individuals are motivated to engage in sex primarily because of physical pleasure and relational intimacy. The couples who valued sex primarily for relational intimacy were more likely to successfully adjust to changes in sexual function than those who primarily valued sex for physical pleasure. The attributes of acceptance, flexibility, and persistence helped sustain couples through the process of adjustment. Based on these findings, a new theory, the Physical Pleasure-Relational Intimacy Model of Sexual Motivation (PRISM) is presented. The results elucidate the main motives for engaging in sexual activity-physical pleasure and/or relational intimacy-as a determining factor in the successful maintenance of satisfying sexual intimacy after PrCa treatment. The PRISM model predicts that couples who place a greater value on sex for relational intimacy will better adjust to the sexual challenges after PrCa treatment than couples who place a lower value on sex for relational intimacy. Implications of the model for counselling are discussed. This model remains to be tested in future research.

Performance of brushite plaster as kidney stone phantoms for laser lithotripsy.

Artificial phantoms used in photothermal near-infrared laser lithotripsy research generally fail to mimic both the chemical and the physical properties of human stones. Though high-energy, 1 J pulses are capable of fracturing hard human stones into several large fragments along natural boundaries, similar behavior has not been observed in commonly used gypsum plasters like BegoStone. We developed a new brushite-based plaster formulation composed of ≈90% brushite that undergoes rapid fracture in the manner of human stones under fragmentation pulse regimes. Single-pulse (1 J) ablation crater volumes for phantoms were not significantly different from those of pure brushite stones. Control over crater volumes was demonstrated by varying phosphorous acid concentration in the plaster formulation. Fragmentation of cylindrical brushite phantoms was filmed using a high-speed camera which demonstrated rapid fragmentation in < 100 µs during the bubble expansion phase of a short pulse from a high-powered Ho:YAG laser (Lumenis Pulse 120 H). The rapid nature of observed fracture suggests increasing laser pulse energy by increasing laser pulse duration will not improve fragmentation performance of laser lithotripters. Brushite plaster phantoms are a superior alternative to gypsum plasters for laser lithotripsy research due to their better mimicry of stone composition, controllable single-pulse crater volumes, and fragmentation behavior.

Sexual adjustment to androgen deprivation therapy: struggles and strategies.

More than half of all men with prostate cancer will be treated with androgen deprivation therapy (ADT) at some point during their lives. Though an effective treatment for prostate cancer, ADT results in profound changes in the man's sense of masculinity and sexuality (e.g., erectile dysfunction, loss of libido, genital atrophy and severe genital shrinkage, hot flashes, loss of muscle mass, fatigue, bodily feminization). These changes usually result in the cessation of all sexual activity. Surprisingly, some couples do find ways of continuing to have satisfying sex despite the man's castrate level of testosterone. Herein, we describe the sexual struggles that couples encounter when attempting to adapt sexually to ADT. A grounded theory methodology was used to analyze interview data. The successful strategies that couples used to overcome struggles, as well as those which seemed to exacerbate struggles, are documented. Couples adjusting to ADT might benefit from knowing which strategies are most likely to result in positive adjustment and which are not.

A description of heterosexual couples' sexual adjustment to androgen deprivation therapy for prostate cancer.

OBJECTIVE: It is estimated that 600,000 men are currently living in North America with castrate levels of testosterone as a result of androgen deprivation therapy for prostate cancer. The goal of this study was to explore how patients and their partners adjust to changes associated with androgen deprivation therapy (ADT). METHODS: Eighteen couples were interviewed regarding their adjustment to ADT side effects. RESULTS: Three distinct patterns of adjustment were observed. One group of couples had assumed sex to be impossible after commencing ADT, and quickly accepted the loss of sex in exchange for a life extending treatment (four couples). Another group was found to be struggling to either maintain satisfying sex or adapt to the loss of their sexual relationship (five couples). The third group had struggled, but found that they were satisfied with their sexual outcome (nine couples). A subset of these couples successfully adjusted to changes in the man's sexual function and found satisfying ways to be sexually active (five couples). CONCLUSIONS: The finding that some couples are able to enjoy satisfying sex, despite castrate levels of testosterone, raised questions about how patients are prepared to undergo ADT and how they are managed. It is possible that both the couples who gave up on sex because they believed that satisfying sex was impossible, and the couples who continued to struggle to adjust, may have faired better if they had known how other couples are able to maintain satisfying sex while the man is androgen-deprived.

Distress and psychosocial needs of a heterogeneous high risk familial cancer population.

In order to assess the levels of distress and psychosocial support needs of a high risk population, we undertook a study to look at both the objective and subjective levels of distress and the wants and needs of individuals from a high familial cancer risk population. Three hundred and eighteen individuals (160 affected, 158 unaffected) completed several distress and psychosocial needs questionnaires (including the Brief Symptom Inventory-18). Sixty key informants were also surveyed about their perspective on the support needs of this population. In the largely female (90%), largely HBOC syndrome group (approximately 90%), 20% had significant levels of generalized distress, with no significant differences between affected and unaffected individuals. Generalized distress was also not significantly different as a function of mutation status. Individuals who received inconclusive test results, however, were more likely to indicate somatic symptoms of distress. Those individuals who did not have social support were more likely to be those who had never had cancer and who either had a mutation, received inconclusive test results, or were not tested. Key informants were most likely to indicate that patients need more support. These results provide evidence for the importance of establishing regular psychosocial distress screening, including a focus on somatic symptoms, in such high risk populations.
