976-14 Immediate Heart Rate Response to Orthostatic Stress During ÎČ-blocker Therapy for Vasodepressor Syncope
Although ÎČ-blockers are preferred agents for therapy of vasodepressor syncope (VDS), they are not uniformly effective and their mechanism of action is incompletely understood. Since we have previously shown a differential therapeutic response to ÎČ-blocker therapy between pts with isoproterenol-independent [iso(-)] and isoproterenol-dependent [iso(+)] VDS during tilt table testing we sought to determine whether this was due to a differential heart rate (HR) response to orthostasis during ÎČ-blockade. We therefore examined immediate HR and blood pressure responses to upright tilt before and after initiation of therapy with atenolol (12.5â50mg daily) in 62 pts with VDS and positive tilt tests. The protocol comprised upright tilt (60°) for up to 60min followed by repeat tilt for 15min during isoproterenol (iso) infusion. Supine HR, mean arterial pressure (MAP) and pulse pressure (PP) were determined as the mean of 3 consecutive 1-min samples during supine rest; orthostatic HR, MAP, and PP were the mean of the samples recorded in the first 3min after upright tilt (before infusion of iso). Response to atenolol required completion of tilt with and without infusion of iso. There were 15 iso(-) pts and 47 iso(+) pts. The groups did not differ significantly in blood pressure response (MAP, PP) to orthostasis. Supine HR fell and the ÎHR in response to orthostasis was blunted during therapy in both groups:Baseline (Mean ± SD)Rx (Mean ± SD)Iso(+)Iso(-)pIso(+)Iso(-)pSupine HR69±1368±9NS57±958±8NSOrthostatic ÎHR8±712±9NS3±53±4NS11 iso(-) pts (73%) had a therapeutic response to ÎČ-blockade compared with 46 iso(+) pts (98%, p=0.01); the orthostatic ÎHR in the iso(-) pts who failed ÎČ-blocker therapy was no different from the response in the patients with a therapeutic response.ConclusionsThe HR response to orthostasis is comparably blunted after ÎČ-blockade in pts with iso(-) and iso(+) VDS, indicating that failure to respond is not due to inadequate ÎČ-blockade and suggests that in some pts iso-independent VDS may be independent of a cardiac ÎČ1 receptor mediated mechanism
Patients educating health care providers on Lynch syndrome
Objective: Lynch syndrome (LS) patients are at an elevated risk for early-onset cancers, including endometrial and colorectal (CRC). Prior research has shown a deficit in provider knowledge of LS, which may affect patient satisfaction and adherence to recommended screening and surveillance regimens. Studies suggest patients with LS may educate providers perceived as lacking LS knowledge; however, little is known about these interactions. The goal of this study is to assess patient-reported outcomes from clinical interactions where LS patients educate their providers.
Methods: Participants (n=55) were asked to complete an in-depth telephone interview.
Results: Out of 55 participants, approximately two-thirds (n=37) reported engaging in educational interactions. Participants reported feeling satisfied with the provider response in over half of the reported educational interactions (n=24). Participants reported changes in their patient-provider relationship ranging from improvements in their relationship to termination of services. Conclusion: Patients with LS report educating providers on their diagnosis as well as their screening and surveillance requirements. Patient-reported outcomes of these educational interactions vary based on the providerâs response to the interaction. Providers should be open and receptive to these educational interactions and follow-up on the discussion to improve patient satisfaction
The rate of the founder Jewish mutations in BRCA1 and BRCA2 in prostate cancer patients in Israel
Inherited predisposition occurs in 5â10% of all prostate cancer (CaP) patients, but the genes involved in conferring genetic susceptibility remain largely unknown. Several lines of evidence indicate that germline mutations in BRCA1 and BRCA2 might be associated with an increased risk for CaP. Three mutations in these two genes (185delAG and 5382InsC (BRCA1) and 6174delT (BRCA2) occur in about 2.5% of the general Ashkenazi population, and the 185delAG BRCA1 mutation, in up to 1% of non-Ashkenazi Jews. In order to assess the contribution of these germline mutations to prostate cancer in Jewish Israeli patients, we tested 174 unselected prostate cancer patients (95 of Ashkenazi origin) for these mutations by PCR amplification and modified restriction enzyme digests. Patientâs age range was 45â81 years (median 66), and in 24 (14.4%) the disease was diagnosed prior to 55 years of age. Nineteen (11%) and 12 (6.9%) patients had a first or second degree relative with CaP or breast cancer, respectively. Overall, five mutation carriers were detected: 2/152 (1.3%) 185delAG, 2/104 (2%) 5382InsC, and 1/158 (0.6%) 6174delT. In all carriers, the disease was diagnosed after the age of 55, and only one of them had a family history of breast and CaP. In addition, no allelic losses at the BRCA1 locus were demonstrated in 17 patients with a family history of CaP, using seven microsatellite markers. We conclude that the rate of the predominant Jewish BRCA1 and BRCA2 mutations in CaP patients does not significantly differ from that of the general population, and that mutational inactivation of the BRCA1 is rare in familial CaP. Thus, germline BRCA1 and BRCA2 mutations probably contribute little to CaP occurrence, to inherited predisposition, and to early onset disease in Jewish individuals. © 2000 Cancer Research Campaig
Nebuliser therapy in the intensive care unit
The relationship between identity, lived experience, sexual practices and the language through which these are conveyed has been widely debated in sexuality literature. For example, âcoming outâ has famously been conceptualised as a âspeech actâ (Sedgwick 1990) and as a collective narrative (Plummer 1995), while a growing concern for individualsâ diverse identifications in relations to their sexual and gender practices has produced interesting research focusing on linguistic practices among LGBT-identified individuals (Leap 1995; Kulick 2000; Cameron and Kulick 2006; Farqhar 2000). While an explicit focus on language remains marginal to literature on sexualities (Kulick 2000), issue of language use and translation are seldom explicitly addressed in the growing literature on intersectionality. Yet intersectional perspectives âreject the separability of analytical and identity categoriesâ (McCall 2005:1771), and therefore have an implicit stake in the âvernacularâ language of the researched, in the âscientificâ language of the researcher and in the relationship of continuity between the two. Drawing on literature within gay and lesbian/queer studies and cross-cultural studies, this chapter revisits debates on sexuality, language and intersectionality. I argue for the importance of giving careful consideration to the language we choose to use as researchers to collectively define the people whose experiences we try to capture. I also propose that language itself can be investigated as a productive way to foreground how individual and collective identifications are discursively constructed, and to unpack the diversity of lived experience. I address intersectional complexity as a methodological issue, where methodology is understood not only as the methods and practicalities of doing research, but more broadly as âa coherent set of ideas about the philosophy, methods and data that underlie the research process and the production of knowledgeâ (McCall 2005:1774). My points are illustrated with examples drawn from my ethnographic study on âlesbianâ identity in urban Russia, interspersed with insights from existing literature. In particular, I aim to show that an explicit focus on language can be a productive way to explore the intersections between the global, the national and the local in cross-cultural research on sexuality, while also addressing issues of positionality and accountability to the communities researched
The use of implantable cardioverter defibrillators in Iceland: a retrospective population based study
BACKGROUND: Indications for implantable cardioverter defibrillator (ICD) implantation have expanded considerably in recent years, resulting in steadily growing numbers of ICD recipients worldwide. The aim of this study was to review the overall experience with ICDs in Iceland. METHODS: This was a retrospective single centre study set at the University Hospital in Iceland. Data on all ICD implantations in Iceland from the first implantation in 1992 till the end of 2002 was reviewed. RESULTS: Sixty-two patients (71% male) received an ICD during this period. There was an increase in the number of implants by year and the number of new implants in 2001 and 2002 amounted to 56 and 38 per million, respectively. The mean age at implantation was 58 (+/-14) years. Forty patients (65%) had coronary artery disease. The most common indications for ICD implantation were cardiac arrest, 32 (52%) and another 26 (42%) had experienced ventricular tachycardia without cardiac arrest. The most common adverse event was inappropriate shocks. Twenty-eight patients (45%) received therapy from their ICDs, with the majority receiving appropriate therapy. Of the thirteen patients deceased before or during the study period, no case of sudden arrhythmic death was observed. CONCLUSION: This study shows that the experience with ICDs in Iceland is in most respects similar to other Western countries
Are men well served by family planning programs?
Although the range of contraceptives includes methods for men, namely condoms, vasectomy and withdrawal that men use directly, and the Standard Days Method (SDM) that requires their participation, family planning programming has primarily focused on women. What is known about reaching men as contraceptive users? This paper draws from a review of 47 interventions that reached men and proposes 10 key considerations for strengthening programming for men as contraceptive users. A review of programming shows that men and boys are not particularly well served by programs. Most programs operate from the perspective that women are contraceptive users and that men should support their partners, with insufficient attention to reaching men as contraceptive users in their own right. The notion that family planning is womenâs business only is outdated. There is sufficient evidence demonstrating menâs desire for information and services, as well as menâs positive response to existing programming to warrant further programming for men as FP users. The key considerations focus on getting information and services where men and boys need it; addressing gender norms that affect menâs attitudes and use while respecting womenâs autonomy; reaching adolescent boys; including men as users in policies and guidelines; scaling up successful programming; filling gaps with implementation research and monitoring & evaluation; and creating more contraceptive options for men
Further evidence of psychological factors underlying choice of elective cesarean delivery (ECD) by primigravidae
Objective: Requests for elective cesarean delivery (ECD) have increased in Iran. While some sociodemographic and fear-related factors have been linked with this choice, psychological factors such as self-esteem, stress, and health beliefs are under-researched. Methods: A total of 342 primigravidae (mean age = 25 years) completed questionnaires covering psychological dimensions such as self-esteem, perceived stress, marital relationship quality, perceived social support, and relevant health-related beliefs. Results: Of the sample, 214 (62.6%) chose to undergo ECD rather than vaginal delivery (VD). This choice was associated with lower self-esteem, greater perceived stress, belief in higher susceptibility to problematic birth and barriers to an easy birth, along with lower perceived severity of ECD, fewer perceived benefits from VD, lower self-efficacy and a lower feeling of preparedness. No differences were found for marital relationship quality or perceived social support. Conclusions: The pattern suggests that various psychological factors such as self-esteem, self-efficacy, and perceived stress underpin the decision by primigravidae to have an ECD
A View from the Past Into our Collective Future: The Oncofertility Consortium Vision Statement
Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-of-life issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity. The goals are to continually integrate the best science in the service of the needs of patients and build a community of care that is ready for the challenges of the field in the future
âA Hideous Torture on Himselfâ: Madness and Self-Mutilation in Victorian Literature
This paper suggests that late nineteenth-century definitions of self-mutilation, a new category of psychiatric symptomatology, were heavily influenced by the use of selfinjury as a rhetorical device in the novel, for the literary text held a high status in Victorian psychology. In exploring Dimmesdaleâs âself-mutilationâ in The Scarlet Letter in conjunction with psychiatric case histories, the paper indicates a number of common techniques and themes in literary and psychiatric texts. As well as illuminating key elements of nineteenth-century conceptions of the self, and the relation of mind and body through ideas of madness, this exploration also serves to highlight the social commentary implicit in many Victorian medical texts. Late nineteenth-century England, like mid-century New England, required the individual to help himself and, simultaneously, others; personal charity and individual philanthropy were encouraged, while state intervention was often presented as dubious. In both novel and psychiatric text, self-mutilation is thus presented as the ultimate act of selfish preoccupation, particularly in cases on the âborderlandsâ of insanity
