RESUMEN

Background: Helping people achieve their preferred location of care is an important indicator of quality end-of-life (EOL) care. Using a sample of Australian medical oncology outpatients, this study examined (1) their preferred location of EOL care; (2) their perceived benefits and worries of receiving care in that location; (3) the percentage who had discussed preferences with their doctor and/or support person; and (4) whether they wanted their doctor to ask them where they wanted to die. Methods: Adults with a confirmed diagnosis of cancer were approached between September 2015 and January 2016 in the waiting room of an Australian oncology outpatient clinic. Consenting participants completed a home-based pen-and-paper survey indicating preferred location of care, perceived benefits and worries of that location, whether they had discussed preferences with their doctors, and whether they were willing to be asked about their preferences. Results: A total of 203 patients returned the survey (47% of those eligible). Less than half preferred to be cared for at home (47%), 34% preferred a hospice/palliative care unit, and 19% preferred the hospital. Common benefits and worries associated with locations included perceived burden on others, familiarity of environment, availability of expert medical care, symptom management, and likelihood of having wishes respected. More patients had discussed preferences with their support persons (41%) than doctors (7%). Most wanted a doctor to ask them about preferred location of care (87%) and thought it was important to die in the location of their choice (93%). Conclusions: Patients were willing to have clinicians to ask them where they wanted to die, although few had discussed their preferences with doctors. Although home was the most preferred location for many patients, the overall variation suggests that clinicians should adopt a systematic approach to eliciting patient preferences.

RESUMEN

Objectives: This study surveyed a sample of medical oncology outpatients to determine (1) the proportion who have already discussed and documented their end-of-life (EOL) wishes; (2) when and with whom they would prefer to convey their EOL wishes; (3) the EOL issues they would want to discuss; and (4) the association between perceived cancer status and advance care planning (ACP) participation. Methods: Adult medical oncology outpatients were approached in the waiting room of an Australian tertiary treatment center. Consenting participants completed a pen-and-paper survey assessing participation in ACP, preferences for conveying EOL wishes, timing of EOL discussions, and EOL issues they want to be asked about. Results: A total of 203 patients returned the survey (47% of eligible). EOL discussions occurred more frequently with support persons (47%) than with doctors (7%). Only 14% had recorded their wishes, and 45% had appointed an enduring guardian. Those who perceived their cancer as incurable were more likely to have participated in ACP. If facing EOL, patients indicated that they would want family involved in discussions (85%), to be able to write down EOL wishes (82%), and to appoint enduring guardians (91%). Many (45%) preferred the first discussion to happen when their disease became incurable. Slightly less than one-third thought discussions regarding EOL should be patient-initiated. Most agreed doctors should ask about preferred decision-making involvement (92%), how important it is that pain is managed well (95%), and how important it is to remain conscious (82%). Fewer (55%) wanted to be asked about the importance of care extending life. Conclusions: Many patients would like to have discussions regarding EOL care with their doctor and involve their support persons in this process. Only a small percentage of respondents had discussed EOL care with their doctors, recorded their wishes, or appointed an enduring guardian. The first step requires clinicians to ask whether an individual patient wishes to discuss EOL issues, in what format, and at what level of detail.

RESUMEN

Background: Neoadjuvant systemic therapy (NAST) is an increasingly used treatment option for women with large operable or highly proliferative breast cancer. With equivalent survival outcomes between NAST and up-front surgery, the situation-specific preference-sensitive nature of the decision makes it suitable for a decision aid (DA). This study aimed to develop and evaluate a DA for this population. Methods: A DA booklet was developed according to international standards, including information about adjuvant and neoadjuvant treatment, outcome probabilities, and a values clarification exercise. Eligible women, considered by investigators as candidates for NAST, were enrolled in a multi-institutional, single-arm, longitudinal study. Patient-reported outcome measure questionnaires were completed pre- and post-DA, between chemotherapy and surgery, and at 12 months. Outcomes were feasibility (percentage of eligible patients accessing the DA); acceptability to patients (percentage who would recommend it to others) and clinicians (percentage who would use the DA in routine practice); and decision-related outcomes. Results: From 77 eligible women, 59 were enrolled, of whom 47 (79.7%; 95% CI, 69.4-89.9) reported having read the DA; 51 completed the first post-DA questionnaire. Of these 51, 41 participants (80.4%; 95% CI, 69.5-91.3) found the DA useful for their decision about NAST. Of 18 responding investigators, 16 (88.9%; 95% CI, 74.4-103.4) indicated they would continue to use the DA in routine practice. Post-DA, decisional conflict decreased significantly (P<.01); anxiety and distress decreased significantly; and 86.3% (95% CI, 73.7-94.3) achieved at least as much decisional control as they desired. Conclusions: This DA was feasible and acceptable to patients and clinicians, and improvement in decision-related outcomes was demonstrated when used in combination with clinical consultations. This DA could safely be implemented into routine practice for women considering NAST for operable breast cancer.

RESUMEN

The periodontal pathogen Porphyromonas gingivalis can invade host cells, a virulence trait which may contribute to the persistence of infection at subgingival sites. Whilst the antibiotic protection assay has been commonly employed to investigate and quantify P. gingivalis invasion, data obtained have varied widely and a thorough investigation of the factors influencing this is lacking. We investigated the role of a number of bacterial and host-cell factors and report that the growth phase of P. gingivalis, source (laboratory strain vs. clinical strain), host-cell identity (cell line vs. primary), host-cell lysis method, and host-cell passage number had no significant effect on bacterial invasion. However, incubation time, host-cell seeding density, method of quantification (viable count vs. DNA), and whether host cells were plated or in suspension, were shown to influence invasion. Also, cells isolated by rapid adhesion to fibronectin exhibited higher levels of P. gingivalis invasion, possibly as a result of increased levels of active α5ß1 integrin. Interestingly, this may represent a population of cells with stem cell-like properties. This study provides important new information by identifying the most important factors that influence P. gingivalis invasion assays and may help to explain variations in the levels previously reported.

RESUMEN

BACKGROUND: The perceptions of those called on to make decisions on behalf of patients who lack capacity at the end of life must accurately reflect patient preferences. AIMS: To establish the extent to which the views of medical oncology outpatients are understood by their support persons, specifically with regards to (i) preferred type and location of end-of-life care, (ii) preferred level of involvement in end-of-life decision-making and (iii) whether the patient has completed an advance care plan or appointed an enduring guardian. METHODS: Adults with a confirmed cancer diagnosis and their nominated support persons were approached between September 2015 and January 2016 in the waiting room of an Australian tertiary referral clinic. Consenting participants completed a pen-and-paper survey. Nominated support persons answered the same questions from the patient's perspective. RESULTS: In total, 208 participants (39% of eligible dyads) participated. Observed agreement across the five outcomes ranged from 54% to 84%. Kappa values for concordance between patient-support person responses were fair to moderate (0.24-0.47) for enduring guardian, decision-making, advance care plan and care location outcomes. A slight level of concordance (k = 0.15; 95% confidence interval: -0.02, 0.32) was found for the type of care outcome. CONCLUSION: Relying on support persons' views does not guarantee that patients' actual preferences will be followed. Strategies that make patient preferences known to healthcare providers and support persons while they still have the capacity to do so is a critical next step in improving quality cancer care.

RESUMEN

Two case studies are presented as a focus for discussion of ethics in addiction medicine. The first is that of the alcohol-dependent patient who receives a liver transplant. The second is that of a heroin-dependent patient who continues to inject himself while in a general medical ward. I make some comments about the obligations of doctors to treat those who cause harm to themselves as they would treat those who are 'not responsible'.

RESUMEN

AIM: To determine whether combinations of enzymes in gingival crevicular fluid (GCF) can act as improved biomarkers compared with single enzymes for predicting the outcome of treatment and also for diagnosing the clinical status of sites. METHODS: Thirty subjects with chronic periodontitis were recruited to a 12-month longitudinal pilot study. GCF samples from three representative sites: healthy (≤3 mm), deep non-bleeding (NB) (≥6 mm) and deep bleeding (DB) (≥6 mm) sites and clinical data were collected at baseline, 3 months, 6 months and 12 months following periodontal treatment. Active enzyme levels (MMP-8, cathepsin G, elastase, trypsin-like activity and sialidase) in GCF samples were assessed. The enzyme profiles and clinical data of each site were analysed for correlation and logistic regression was performed to find the predictive value of the active enzyme levels regarding the outcome of treatment. RESULTS: Twenty-two individuals completed the study. All active enzyme levels were significantly higher in diseased sites than healthy sites. Logistic regression showed that the combination of MMP8, elastase and sialidase provided accurate predictions of treatment outcome (88% for NB and 86% for DB), which was significantly better than each enzyme alone (61%). CONCLUSION: This pilot has suggested that combined active enzyme profiling could provide significant prediction of outcome of treatment.

RESUMEN

In an article somewhat ironically entitled "Disambiguating Clinical Intentions," Lynn Jansen promotes an idea that should be bewildering to anyone familiar with the literature on the intention/foresight distinction. According to Jansen, "intention" has two commonsense meanings, one of which is equivalent to "foresight." Consequently, questions about intention are "infected" with ambiguity-people cannot tell what they mean and do not know how to answer them. This hypothesis is unsupported by evidence, but Jansen states it as if it were accepted fact. In this reply, we make explicit the multiple misrepresentations she has employed to make her hypothesis seem plausible. We also point out the ways in which it defies common sense. In particular, Jansen applies her thesis only to recent empirical research on the intentions of doctors, totally ignoring the widespread confusion that her assertion would imply in everyday life, in law, and indeed in religious and philosophical writings concerning the intention/foresight distinction and the Principle of Double Effect.

RESUMEN

OBJECTIVE: The objective of this study was to explore changes in the sexual function of women who attended a rural nurse-led female sexual dysfunction clinic. DESIGN: This exploratory study was designed as a one-group pre-test/post-test design from a convenience sample of women attending the clinic. SETTING: The setting was a women's health centre located in regional Western Australia. PARTICIPANTS: One hundred eleven women aged between 18 and 65 years were recruited from clinic attendees. MAIN OUTCOME MEASURE(S): The Australian version of the validated McCoy Female Sexuality Questionnaire was completed before the first appointment (T0), and 1 (T1) and 6 months (T2) after the last appointment. RESULTS: Women attending the clinic reported significant increases in sexual desire, satisfaction and orgasm quality and achievement at 1 and 6 months after their last appointment. There was also a significant increase in satisfaction with their main sexual partner at 6 months. CONCLUSIONS: This study confirmed the value of an innovative approach to managing female sexual dysfunction in a rural area with workforce shortages and limited health services. It is recommended that care by a nurse-led multidisciplinary team be used in the management of sexual dysfunction. Further research is needed to see if this model of care would be effective in other settings.

RESUMEN

BACKGROUND: The keystone flap is being promoted as an advance in oncological surgical reconstruction. Wound closure with this island flap involves two V-Y advancements toward the center and along the long axis of the island, at right angles to the line of maximum tension when the wound is closed. It is implied that the long-axis advancements enable closure by relaxing the entire flap of skin, allowing it to be stretched more easily along the short axis. We undertook a study to test this hypothesis. METHODS: We measured tension and extension along perpendicular axes in nine freshly excised specimens of human skin. We held the longitudinal axis fixed while stretching the skin along the transverse axis. We then released the longitudinal axis and measured the resultant drop in transverse tension. Finally, we increased the transverse tension to approximately its previous level, and measured the new transverse extension. RESULTS: There was significant interdependence between longitudinal and transverse tensions. The fall in transverse wound tension associated with longitudinal release varied with starting tensions and with the original site and orientation of the specimen. In the five cases where the longitudinal release was from the in vivo length, the mean increase in transverse stretch attributable to the release was 0.6 mm (95% confidence interval 0.1-1.1 mm). DISCUSSION: The increase in transverse stretch that can be achieved by releasing skin from its longitudinal in vivo length appears trivial, raising questions about the rationale for the use of the prototypical (type 1) keystone flap in wound closure.

RESUMEN

AIM: To investigate the effects of psychosocial stress on the outcome of non-surgical periodontal treatment (NPT). METHODS: Patients were categorized as stressed or unstressed, and the degree of stress was measured. One deep bleeding and one deep non-bleeding site ≥6 mm were selected in each patient for detailed investigation, and the clinical parameters were recorded before and at 6 months after NPT. Elastase and C-terminal teleopeptide of type I collagen (ICTP) were measured in gingival crevicular fluid (GCF) samples at both intervals. RESULTS: The baseline, clinical parameters and biological markers were similar in both stressed and unstressed groups, other than for GCF elastase levels, which were significantly higher in the stressed group of patients (p < 0.05). The effect of stress on the changes for clinical measurements and elastase levels in GCF was statistically significant for deep bleeding sites, with the response to treatment being poorer in the stressed group. The effects of smoking and the degree of stress were not statistically significant for any of the clinical or biological parameters (p > 0.05). CONCLUSIONS: Patients under psychosocial stress had a poorer outcome following NPT. The assessment of psychosocial stress may be valuable in the holistic management of periodontal disease.

RESUMEN

The moral importance of the 'intention-foresight' distinction has long been a matter of philosophical controversy, particularly in the context of end-of-life care. Previous empirical research in Australia has suggested that general physicians and surgeons may use analgesic or sedative infusions with ambiguous intentions, their actions sometimes approximating 'slow euthanasia'. In this paper, we report findings from a qualitative study of 18 Australian palliative care medical specialists, using in-depth interviews to address the use of sedation at the end of life. The majority of subjects were agnostic or atheistic. In contrast to their colleagues in acute medical practice, these Australian palliative care specialists were almost unanimously committed to distinguishing their actions from euthanasia. This commitment appeared to arise principally from the need to maintain a clear professional role, and not obviously from an ideological opposition to euthanasia. While some respondents acknowledged that there are difficult cases that require considered reflection upon one's intention, and where there may be some 'mental gymnastics,' the nearly unanimous view was that it is important, even in these difficult cases, to cultivate an intention that focuses exclusively on the relief of symptoms. We present four narratives of 'terminal' sedation--cases where sedation was administered in significant doses just before death, and may well have hastened death. Considerable ambiguities of intention were evident in some instances, but the discussion around these clearly exceptional cases illustrates the importance of intention to palliative care specialists in maintaining their professional roles.

RESUMEN

BACKGROUND AND OBJECTIVE: The literature on fine-needle aspiration (FNA) cytology for papillary lesions presents a very mixed picture. Many authors advocate mandatory excision of these lesions. This recommendation is largely based on the 'atypical' nature of the FNA report. The aim of this work is to see if breast papillomas can be treated conservatively. STUDY DESIGN: We report a retrospective study of outcomes for patients with a provisional diagnosis of a 'papillary breast lesion' based on assessment by palpation (no clinically suspicious features), sonography (benign or probably benign according to the Breast Imaging Reporting and Data System 'BI-RADS®'), and FNA (benign cytological category with a papillary architecture) findings from one integrated breast service. RESULTS: Thirty-six cases were identified over a period of 6 years. Thirty-four of the patients had surgical excision. All of the 34 surgical cases were confirmed to be benign in nature on histopathology (intraduct papilloma). The remaining 2 cases were stable on follow-up. CONCLUSION: We believe that a policy of mandatory excision of papillary lesions of the breast is unnecessarily cautious.

RESUMEN

Outpatients can be at heightened risk of COVID-19 due to interaction between existing non-communicable diseases in outpatients and infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study measured the magnitude of COVID-19 prevalence and explored related risk characteristics among adult outpatients visiting medicine clinics within a New York state-based tertiary hospital system. Data were compiled from 63,476 adult patients visiting outpatient medicine clinics within a New York-area hospital system between March 1, 2020, and August 28, 2020. The outcome was a clinical diagnosis of COVID-19. Crude and adjusted prevalence ratios (PR) of a COVID-19 were analyzed using univariable and multivariable Poisson regression with robust standard errors. The prevalence of COVID-19 was higher among these outpatients (3.0%) than in the total population in New York State (2.2%) as of August 28, 2020. Multivariable analysis revealed adjusted prevalence ratios significantly greater than one for male sex (PR=1.10), age 40 to 64 compared to <40 (PR=1.19), and racial/ethnic minorities in comparison to White patients (Hispanic: PR=2.76; Black: PR=1.89; and Asian/others: PR=1.56). Nonetheless, factors including the advanced age of ≥65 compared to <40 (PR=0.69) and current smoking compared to non-smoking (PR=0.60) were related to significantly lower prevalence. Therefore, the prevalence of COVID-19 in outpatients was higher than that of the general population. The findings also enabled hypothesis generation that routine clinical measures comprising sex, age, race/ethnicity, and smoking were candidate risk characteristics of COVID-19 in outpatients to be further verified by designs capable of assessing temporal association.

RESUMEN

BACKGROUND: In late 2006, the seaside community in Esperance, Western Australia, was alerted to thousands of native bird species dying. The source of the lead was thought to derive from the handling of Pb carbonate concentrate from the Magellan mine through the port of Esperance, begun in July 2005. Concern was expressed for the impact of this process on the community. OBJECTIVE: This study was designed to evaluate the source of Pb in blood of a random sample of the community using Pb isotope ratios. METHODS: The cohort comprised 49 children (48 < 5 years of age) along with 18 adults (> 20 years of age) with a bias toward higher blood lead (PbB) values to facilitate source identification. RESULTS: Mean PbB level of the children was 7.5 microg/dL (range, 1.5-25.7 microg/dL; n = 49; geometric mean, 6.6 microg/dL), with four children whose PbB was > 12 microg/dL. The isotopic data for blood samples lay around two distinct arrays. The blood of all children analyzed for Pb isotopes contained a contribution of Pb from the Magellan mine, which for young children ranged from 27% up to 93% (mean, 64%; median, 71%). Subtraction of the ore component gave a mean background PbB of 2.3 mug/dL. Several children whose PbB was > 9 microg/dL and most of the older subjects have complex sources of Pb. CONCLUSIONS: The death of the birds acted as a sentinel event; otherwise, the exposure of the community, arising from such a toxic form of Pb, could have been tragic. Isotopic data and mineralogic and particle size analyses indicate that, apart from the recognized pathway of Pb exposure by hand-to-mouth activity in children, the inhalation pathway could have been a significant contributor to PbB for some of the very young children and in some parents.

RESUMEN

BACKGROUND: Neoadjuvant systemic therapy (NAST) is used for large operable or highly proliferative breast cancers. It is not known whether psychological outcomes differ according to the treatment sequence (chemotherapy or surgery first) or tumour response. METHODS: This was a planned analysis of a multi-institutional single arm longitudinal study of patients considering NAST for operable breast cancer. Participants completed patient reported outcome questionnaires before and after the decision about NAST, between chemotherapy and surgery, and 12 months after diagnosis. RESULTS: Fifty-nine women enrolled. Fourteen of 51 (28%) who received NAST experienced pathological complete response (pCR). Patients who had surgery first (n = 7) had higher baseline anxiety, and a greater decrease in anxiety at 12 months follow up, compared with patients who received NAST (n = 50) (a decrease from baseline of 34 pts vs 17 points; p = 0.033). Distress declined at a similar rate in surgery first and NAST groups. Mean satisfaction with decision score post-decision was significantly lower in the adjuvant group compared with NAST (22 vs 26, p = 0.02). No differences were seen between patients with pCR vs residual cancer in: distress, anxiety, satisfaction with decision, fear of progression, and decision regret. CONCLUSION: Most patients in this study proceeded with NAST when their surgeon offered it as an option. This exploratory analysis suggests that patients who chose surgery first tended to be more anxious, and had lower satisfaction with their decision, than those who had NAST. In patients who had NAST, lack of pCR does not appear to correlate with adverse psychological outcomes.

RESUMEN

A persistent left superior vena cava markedly increases the size of the coronary sinus (CS), which can increase the difficulty of left ventricular (LV) lead placement in patients receiving cardiac resynchronization therapy (CRT). We present a case where the entire superior vena cava drains into the coronary sinus, creating a massive CS. We also describe an interventional approach to LV lead implantation utilizing a combination of delivery systems from different vendors.
