Background Greater understanding of patient-reported barriers and facilitators to seeking and accessing sexual health services will help formulate strategies to assist gynecologic and breast cancer patients to overcome obstacles to accessing sexual health support because they typically do not seek sexual education and/or treatment when confronted with sexual concerns. Aim The objectives of this systematic review were to (i) explore the patient-reported barriers to seeking and accessing support for sexual problems in gynecologic and breast cancer survivors, and (ii) identify strategies used to successfully overcome the barriers to accessing sexual health information and/or treatment. Main Outcome Measures The main outcome measures included factors that prevent and/or facilitate gynecologic and breast cancer patients with sexual concerns seeking and accessing sexual health-related services. Methods Systematic searches of major electronic databases (Ovid MEDLINE, PsycINFO, CINAHL, ProQuest, and Chinese database CNKI) from January 2009 to July 2019 were used to identify the barriers and facilitators to seeking sexual education/treatment from the perspective of gynecologic and breast cancer survivors. A narrative synthesis was conducted. Results 20 studies met the inclusion criteria including 12 qualitative, 6 quantitative, and 2 mixed methods studies. 4 interconnected themes were derived from 13 subthemes relating to the barriers/facilitators to seeking and accessing sexual health support. The most common barriers were embarrassment/discomfort in discussing sexual concerns, perceived discomfort of healthcare providers in discussing sexual issues, limitations of the healthcare system to address sexual problems, and the multidimensional nature of sexuality. Help-seeking for sexual health concerns was facilitated by: (i) oncology health professionals initiating and conducting open, honest discussions around sexual concerns with patients; (ii) the availability of information in multiple forms; and (iii) appropriate timing of information provision according to women's preferences. Clinical Implications Oncology health professionals need to develop an open, honest, accepting communication style and be accessible to women with cancer and their partners within healthcare systems. Strengths & Limitations The systematic review was conducted in accordance with guidelines. Variability in the primary aims and outcomes of the included studies precluded a meta-analysis. Conclusions Training programs for providers of oncology care should enhance their knowledge of sexual issues in gynecologic and/or breast cancer, enhance their communication skills with patients, and improve their ability to consult or refer patients to psycho-oncologists or other mental health professionals.

Background: Few studies have specifically assessed the scope, nature and challenges of palliative and end-of-life care in rural general practice. These knowledge gaps limit the development of evidence-based policies and services for patients in the last months of life. This study aimed to explore the perspectives of general practitioners (GPs) and other stakeholders on rural GPs' involvement and challenges in providing palliative and end-of-life care in regional Australia. Methods: A qualitative study involving five focus groups with 26 GPs based in rural/regional Western Australia together with 15 individual telephone interviews with four GPs and 11 other stakeholders involved in end-of-life care across Australia. Results: The rural GPs' central role in end-of-life care was recognized by the majority of participants but multiple challenges were also identified. Some challenges were comparable to those found in urban settings but others were more pronounced, including resource limitations and lack of training. Inappropriate payment models discouraged GPs' involvement in some aspects of end-of-life care, such as case conferences and home visits. Compared to GPs in urban settings, those in rural/regional communities often reported closer doctor-patient relationships and better care integration and collaboration. These positive aspects of care could be further developed to enhance service provision. Our study highlighted the importance of regular interactions with other professionals and patients in providing end-of-life care, but many GPs and other stakeholders found such interactions more challenging than the more "technical" aspects of care. Conclusions: Rural/regional GPs appear to be disproportionately affected by inappropriate payment models and limited resources, but may benefit from closer doctor-patient relationships and better care integration and collaboration relative to urban GPs. Systematic collection of empirical data on GP management at end-of-life is required to build on these strengths and address the challenges.

The aim of the present study was to correlate in cardiomyopathic hamsters with congestive heart failure the levels of atrial and ventricular atrial natriuretic factor (ANF) messenger RNA (mRNA) with immunoreactive ANF (IR-ANF) plasma levels and the relative amount of IR-ANF released by the whole heart versus isolated ventricles in the Langendorff preparation. High-performance liquid chromotagraphy analysis of the forms of ANF present in plasma and in the Langendorff effluent of whole heart versus isolated ventricles was also performed. As previously found for cardiac IR-ANF, the levels of ANF mRNA decreased gradually in atria and increased in an analogous fashion in ventricles with the severity of congestive heart failure. Plasma IR-ANF levels (C-terminal) were more elevated in moderate than in severe congestive heart failure, as were the IR-ANF levels in the Langendorff effluent of the whole heart. On the contrary, the effluent of isolated ventricles from animals in severe heart failure yielded more IR-ANF than that from hamsters in moderate heart failure. Thus, while the isolated ventricles from controls contributed 35.8% of IR-ANF released by the whole heart, ventricles from hamsters in moderate heart failure contributed 17.5%, and those from hamsters in severe heart failure contributed 73.9%. These results indicate that atrial cardiocytes contribute more IR-ANF than their ventricular counterpart in moderate heart failure and that ventricles are a major source of plasma IR-ANF in severe heart failure. Analysis of IR-ANF from plasma and the Langendorff efituent from whole hearts and isolated ventricles revealed that the ventricles are the major source of the propeptide (and of its cleaved products) found in the circulation of cardiomyopathic hamsters. These results suggest that ANF synthesis and secretion do not increase conjointly in atria but do increase in ventricles during congestive heart failure. (Circulation Research 1989;65:71-82) T he atria in mammals constitute an endocrine gland 1 " 4 that, in the rat, secretes atrial natriuretic factor (ANF), a 28-amino acid peptide (Ser 99-Tyr 126), 5 -6 which is diuretic, natriuretic, vasodilatory, and inhibitory of aldosterone, cortisol, arginine vasopressin, and renin release. In the rat, the N-terminal moiety (Asn 1-Arg 98) of the propeptide (Asn 1-Tyr 126) of ANF (proANF) is also present in the circulation.7 -9 The mechanism by which the peptide is released is not known,

Synthesis-secretion coupling of insulin was measured in four age groups of perfused pancreases taken from Sprague-Dawley rats ranging in age from 2-12 months. The effect of long term (6 h) near-maximal glucose stimulation (300 mg/dl) on both insulin secretion and net insulinogenesis demonstrated an age-related increase in both parameters. Net insulinogenesis as well as total insulin secretion increased linearly as a function of aging. Compared to that in 2-month-old rats, total net insulin synthesis was more than 3-fold greater in 12-month-old rats, slightly less than 3-fold greater in 8-month-old rats, and twice as much in 4-month-old rats. Compared to that in 2-month-old rats, total glucose-stimulated insulin secretion was 3-fold greater in 12-month-old rats, approximately 2.2-fold greater in 8-month-old rats, and about 1.7-fold greater in 4-month-old rats. A shorter term (90 min) glucose stimulation at 150 mg/dl produced an age-related increase in insulin secretion which was relatively comparable to the higher glucose stimulus. Of equal importance is that fact that pancreases from the older rats exhibited the same degree of secretory responsiveness to changing glucose levels as did pancreases from the younger rats. Regardless of age, first phase insulin secretion was approximately twice as much in response to the higher glucose level as to the lower. Similarly, second phase insulin secretion was almost 3 times greater regardless of age. When normalized and reported in terms of insulin content, total insulin secretion was no different as a function of aging during the first 1 h of glucose stimulation (i.e. the first two phases of secretion), but it was significantly elevated in the third secretory phase (2-6 h) by the older rat groups. Total 6-h net insulinogenesis was also greater in the older rat groups. When normalized and reported in terms of total body weight, both insulin synthesis and total insulin secretion became comparable and showed no specific age-related difference. Thus, there is no indication that aging results in an uncoupling of relatively long term (6-h) insulin synthesis-secretion, since both glucose-induced responses parallel one another as a function of aging. Furthermore, reporting insulin secretion and synthesis on the basis of body weight, rather than age, totally normalizes synthesis-secretion coupling of insulin.

BackgroundThere are no processes that routinely assess end-of-life care in Australian general practice. This study aimed to develop a data collection process which could collect observational data on end-of-life care from Australian general practitioners (GPs) via a questionnaire and clinical data from general practice software.MethodsThe data collection process was developed based on a modified Delphi study, then pilot tested with GPs through online surveys across three Australian states and data extraction from general practice software, and finally evaluated through participant interviews.ResultsThe developed data collection process consisted of three questionnaires: Basic Practice Descriptors (32 items), Clinical Data Query (32 items) and GP-completed Questionnaire (21 items). Data extraction from general practice software was performed for 97 decedents of 10 GPs and gathered data on prescriptions, investigations and referral patterns. Reports on care of 272 decedents were provided by 63 GPs. The GP-completed Questionnaire achieved a satisfactory level of validity and reliability. Our interviews with 23 participating GPs demonstrated the feasibility and acceptability of this data collection process in Australian general practice.ConclusionsThe data collection process developed and tested in this study is feasible and acceptable for Australian GPs, and comprehensively covers the major components of end-of-life care. Future studies could develop an automated data extraction tool to reduce the time and recall burden for GPs. These findings will help build a nationwide integrated information network for primary end-of-life care in Australia.

A complex network of atrial natriuretic factor-producing cells has been delineated by biochemical and morphological techniques in the rat ventricular myocardium. The chordae tendineae spuriae (CTS; false tendons) contain ANF mRNA and the ANF propeptide (Asn 1-Tyr 126) as assessed by Northern blot analysis, high-pressure liquid chromatography and immunohisto- and -cytochemistry, using three different affinity-purified antibodies: monoclonal and polyclonal antibodies against C-terminal ANF (Arg 101-Tyr 126) and polyclonal antibodies against N-terminal ANF (Asp 11-Ala 37). Two types of cells harboring ANF-containing secretory granules constitute the CTS: the majority (Purkinje type I) have ultrastructural similarities with both atrial and classical Purkinje fibers. Purkinje type-II fibers resemble working ventricular cardiocytes. Both cell types harbor a large paranuclear Golgi complex. The subendocardial Purkinje network is also made up of these two cell types. In this location, Purkinje type-I fibers form cable-like structures while Purkinje type-II fibers are either located beneath the former or abut directly on the endocardium. The latter are not separated from adjacent working ventricular cardiocytes by connective tissue septa. Coronary arteries and arterioles, as in birds, are surrounded by a cushion of Purkinje type-II fibers which blend with the surrounding myocardium. These results indicate that, in the rat, the entire intraventricular conduction system is constituted of endocrine cells producing ANF.
