The Treatment of Young Transgender People and the Law.

The law has slowly recognised the concept of a transgender person. After initially fixating on someone's physical birth gender, it has now accepted the concept of gender identity. It has been challenged by young people experiencing gender dysphoria seeking medical treatment. Though in recent years it has increasingly accepted the right of such a person to access appropriate treatment, this article suggests further improvements in this area of the law are desirable, including no longer making the distinction between therapeutic and non-therapeutic treatment, reforming the extent of judicial power in this context, and according greater autonomy to mature young people.

Voluntary Assisted Dying, the Conscientious Objector Who Refuses to Facilitate it and Discrimination Law.

This article discusses the aspect of recent voluntary assisted dying (VAD) laws dealing with a health care provider who declines to provide VAD services. While the law permits the provider to do so, it is sometimes less clear what, if anything, they must do to facilitate VAD service provision by others. Legislation in three jurisdictions is silent on the matter. This article considers refusals to facilitate VAD services, in light of human rights provisions, particularly anti-discrimination legislation, and the guidance available internationally. Existing VAD literature does not consider discrimination arguments in relation to refusal to participate.

Automated screening for distress: A perspective for the future.

Distress is a complex condition, which affects a significant percentage of cancer patients and may lead to depression, anxiety, sadness, suicide and other forms of psychological morbidity. Compelling evidence supports screening for distress as a means of facilitating early intervention and subsequent improvements in psychological well-being and overall quality of life. Nevertheless, despite the existence of evidence-based and easily administered screening tools, for example, the Distress Thermometer, routine screening for distress is yet to achieve widespread implementation. Efforts are intensifying to utilise innovative, cost-effective methods now available through emerging technologies in the informatics and computational arenas.

A Symptom-Triggered Benzodiazepine Protocol Utilizing SAS and CIWA-Ar Scoring for the Treatment of Alcohol Withdrawal Syndrome in the Critically Ill.

BACKGROUND: There are limited data on the efficacy of symptom-triggered therapy for alcohol withdrawal syndrome (AWS) in the intensive care unit (ICU). OBJECTIVE: To evaluate the safety and efficacy of a symptom-triggered benzodiazepine protocol utilizing Riker Sedation Agitation Scale (SAS) scoring for the treatment of AWS in the ICU. METHODS: We performed a before-and-after study in a medical ICU. A protocol incorporating SAS scoring and symptom-triggered benzodiazepine dosing was implemented in place of a protocol that utilized the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale and fixed benzodiazepine dosing. RESULTS: We enrolled 167 patients (135 in the preintervention and 32 in the postintervention group). The median duration of AWS was shorter in the postintervention (5, interquartile range [IQR] = 4-8 days) than in the preintervention group (8, IQR = 5-12 days; P < 0.01). Need for mechanical ventilation (31% vs 57%, P = 0.01), median ICU length of stay (LOS; 4, IQR = 2-7, vs 7, IQR = 4-11 days, P = 0.02), and hospital LOS (9, IQR = 6-13, vs 13, IQR = 9-18 days; P = 0.01) were less in the postintervention group. There was a reduction in mean total benzodiazepine exposure (74 ± 159 vs 450 ± 701 mg lorazepam; P < 0.01) in the postintervention group. CONCLUSION: A symptom-triggered benzodiazepine protocol utilizing SAS in critically ill patients is associated with a reduction in the duration of AWS treatment, benzodiazepine exposure, need for mechanical ventilation, and ICU and hospital LOS compared with a CIWA-Ar-based protocol using fixed benzodiazepine dosing.

Clinical Practice Guidelines for Sustained Neuromuscular Blockade in the Adult Critically Ill Patient.

OBJECTIVE: To update the 2002 version of "Clinical practice guidelines for sustained neuromuscular blockade in the adult critically ill patient." DESIGN: A Task Force comprising 17 members of the Society of Critical Medicine with particular expertise in the use of neuromuscular-blocking agents; a Grading of Recommendations Assessment, Development, and Evaluation expert; and a medical writer met via teleconference and three face-to-face meetings and communicated via e-mail to examine the evidence and develop these practice guidelines. Annually, all members completed conflict of interest statements; no conflicts were identified. This activity was funded by the Society for Critical Care Medicine, and no industry support was provided. METHODS: Using the Grading of Recommendations Assessment, Development, and Evaluation system, the Grading of Recommendations Assessment, Development, and Evaluation expert on the Task Force created profiles for the evidence related to six of the 21 questions and assigned quality-of-evidence scores to these and the additional 15 questions for which insufficient evidence was available to create a profile. Task Force members reviewed this material and all available evidence and provided recommendations, suggestions, or good practice statements for these 21 questions. RESULTS: The Task Force developed a single strong recommendation: we recommend scheduled eye care that includes lubricating drops or gel and eyelid closure for patients receiving continuous infusions of neuromuscular-blocking agents. The Task Force developed 10 weak recommendations. 1) We suggest that a neuromuscular-blocking agent be administered by continuous intravenous infusion early in the course of acute respiratory distress syndrome for patients with a PaO2/FIO2 less than 150. 2) We suggest against the routine administration of an neuromuscular-blocking agents to mechanically ventilated patients with status asthmaticus. 3) We suggest a trial of a neuromuscular-blocking agents in life-threatening situations associated with profound hypoxemia, respiratory acidosis, or hemodynamic compromise. 4) We suggest that neuromuscular-blocking agents may be used to manage overt shivering in therapeutic hypothermia. 5) We suggest that peripheral nerve stimulation with train-of-four monitoring may be a useful tool for monitoring the depth of neuromuscular blockade but only if it is incorporated into a more inclusive assessment of the patient that includes clinical assessment. 6) We suggest against the use of peripheral nerve stimulation with train of four alone for monitoring the depth of neuromuscular blockade in patients receiving continuous infusion of neuromuscular-blocking agents. 7) We suggest that patients receiving a continuous infusion of neuromuscular-blocking agent receive a structured physiotherapy regimen. 8) We suggest that clinicians target a blood glucose level of less than 180 mg/dL in patients receiving neuromuscular-blocking agents. 9) We suggest that clinicians not use actual body weight and instead use a consistent weight (ideal body weight or adjusted body weight) when calculating neuromuscular-blocking agents doses for obese patients. 10) We suggest that neuromuscular-blocking agents be discontinued at the end of life or when life support is withdrawn. In situations in which evidence was lacking or insufficient and the study results were equivocal or optimal clinical practice varies, the Task Force made no recommendations for nine of the topics. 1) We make no recommendation as to whether neuromuscular blockade is beneficial or harmful when used in patients with acute brain injury and raised intracranial pressure. 2) We make no recommendation on the routine use of neuromuscular-blocking agents for patients undergoing therapeutic hypothermia following cardiac arrest. 3) We make no recommendation on the use of peripheral nerve stimulation to monitor degree of block in patients undergoing therapeutic hypothermia. 4) We make no recommendation on the use of neuromuscular blockade to improve the accuracy of intravascular-volume assessment in mechanically ventilated patients. 5) We make no recommendation concerning the use of electroencephalogram-derived parameters as a measure of sedation during continuous administration of neuromuscular-blocking agents. 6) We make no recommendation regarding nutritional requirements specific to patients receiving infusions of neuromuscular-blocking agents. 7) We make no recommendation concerning the use of one measure of consistent weight over another when calculating neuromuscular-blocking agent doses in obese patients. 8) We make no recommendation on the use of neuromuscular-blocking agents in pregnant patients. 9) We make no recommendation on which muscle group should be monitored in patients with myasthenia gravis receiving neuromuscular-blocking agents. Finally, in situations in which evidence was lacking or insufficient but expert consensus was unanimous, the Task Force developed six good practice statements. 1) If peripheral nerve stimulation is used, optimal clinical practice suggests that it should be done in conjunction with assessment of other clinical findings (e.g., triggering of the ventilator and degree of shivering) to assess the degree of neuromuscular blockade in patients undergoing therapeutic hypothermia. 2) Optimal clinical practice suggests that a protocol should include guidance on neuromuscular-blocking agent administration in patients undergoing therapeutic hypothermia. 3) Optimal clinical practice suggests that analgesic and sedative drugs should be used prior to and during neuromuscular blockade, with the goal of achieving deep sedation. 4) Optimal clinical practice suggests that clinicians at the bedside implement measure to attenuate the risk of unintended extubation in patients receiving neuromuscular-blocking agents. 5) Optimal clinical practice suggests that a reduced dose of an neuromuscular-blocking agent be used for patients with myasthenia gravis and that the dose should be based on peripheral nerve stimulation with train-of-four monitoring. 6) Optimal clinical practice suggests that neuromuscular-blocking agents be discontinued prior to the clinical determination of brain death.

The Australian quarantine and biosecurity legislation: Constitutionality and critique.

Australia's quarantine and biosecurity laws have been in focus recently with the serious outbreak of the ebola virus and the not-so-serious incident involving an actor's dogs apparently gaining unauthorised access to Australia. These incidents have coincided with the move to replace Australia's existing quarantine legislation with a modern regulatory framework for managing biosecurity risks. This article critiques the existing and new Australian legislation, comparing them with approaches in other jurisdictions and discussing some relevant public policy issues. In particular, the article comments on the constitutionality of the provisions relating to the detention of individuals for public health reasons, such as to control or limit the spread of disease, finding the new legislation to be an improvement on the existing one.

The effect of a tiered provider staffing model on patient outcomes during the coronavirus disease 2019 pandemic: A single-center observational study.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, our hospital experienced a large influx of critically ill patients with acute respiratory failure. In order to increase intensive care unit (ICU) surge capacity, we adopted a "tiered model" for ICU provider staffing where multiple ICUs were staffed by noncritical care providers under the direction of an intensivist. We hypothesized that ICUs staffed with a tiered model would result in similar patient outcomes as ICU staffed with a traditional intensivist model. METHODS: We performed a single-center, observational study in seven ICUs at a tertiary care center. We included consecutive adults admitted to the ICU with acute respiratory distress syndrome (ARDS) due to COVID-19 infection. We collected baseline demographics, treatments, and outcomes of interest in traditionally staffed ICUs versus ICUs staffed with a tiered model. The primary outcome was inpatient mortality. All outcomes were censored at day 28. RESULTS: We included a total of 138 patients in our study: 66 patients were admitted to traditionally staffed ICUs and 52 were admitted to tiered staffing ICUs. Baseline characteristics were similar between groups. ARDS treatments were similar in traditionally staffed ICUs versus tiered staffing model ICUs, including daily mean tidal volume (6.2 mL/kg vs. 6.2 mL/kg, P = 0.95), median daily fluid balance (159 mL vs. 92 mL, P = 0.54), and use of prone ventilation (58% vs. 65%, P = 0.45). There was no difference in inpatient mortality between groups (50% vs. 42%, P = 0.46). We also found no difference in ventilator-free, ICU-free, vasopressor-free, and dialysis-free days between groups. CONCLUSIONS: Our results suggest that patient outcomes are similar in ICUs with traditional staffing models when compared to ICUs with a tiered staffing mode during a pandemic.

Changing patterns in interventional bronchoscopy.

BACKGROUND AND OBJECTIVE: Many interventional tools for airway disorders can now be delivered via flexible bronchoscopy (FB), including neodymium-yttrium aluminium garnet laser, electrocautery, argon plasma coagulation, cryotherapy, balloon dilatation and metal or hybrid stents. Comparison of outcomes for patients undergoing rigid bronchoscopy (RB) with those treated using FB highlights the usefulness of the FB approach. METHODS: A retrospective medical record review of all interventional bronchoscopy procedures performed at Lahey Clinic over the past 8 years was conducted. Patients were categorized into two groups according to the procedure used, that is, RB (251 patients), and FB (161 patients) groups. Patients with malignancies were included as a separate subgroup, comprising 178 RB and 117 FB patients. For every procedure, the location of the lesion, patient survival from the first interventional procedure performed, and in patients with malignancy, additional treatments received such as chemotherapy and radiation were recorded. RESULTS: Ninety per cent of RB procedures were performed in patients with tracheal or main stem lesions, while over half the patients undergoing FB had more distal lesions. A trend towards increasing use of FB for interventional procedures in recent years was noted. CONCLUSIONS: FB is a valuable alternative to RB for treating less advanced malignant disease or distal airway lesions.

Post tracheostomy and post intubation tracheal stenosis: report of 31 cases and review of the literature.

BACKGROUND: Severe post tracheostomy (PT) and post intubation (PI) tracheal stenosis is an uncommon clinical entity that often requires interventional bronchoscopy before surgery is considered. We present our experience with severe PI and PT stenosis in regards to patient characteristics, possible risk factors, and therapy. METHODS: We conducted a retrospective chart review of 31 patients with PI and PT stenosis treated at Lahey Clinic over the past 8 years. Demographic characteristics, body mass index, co-morbidities, stenosis type and site, procedures performed and local treatments applied were recorded. RESULTS: The most common profile of a patient with tracheal stenosis in our series was a female (75%), obese (66%) patient with a history of diabetes mellitus (35.4%), hypertension (51.6%), and cardiovascular disease (45.1%), who was a current smoker (38.7%). Eleven patients (PI group) had only oro-tracheal intubation (5.2 days of intubation) and developed web-like stenosis at the cuff site. Twenty patients (PT group) had undergone tracheostomy (54.5 days of intubation) and in 17 (85%) of them the stenosis appeared around the tracheal stoma. There was an average of 2.4 procedures performed per patient. Rigid bronchoscopy with Nd:YAG laser and dilatation (mechanical or balloon) were the preferred methods used. Only 1(3.2%) patient was sent to surgery for re-stenosis after multiple interventional bronchoscopy treatments. CONCLUSION: We have identified putative risk factors for the development of PI and PT stenosis. Differences in lesions characteristics and stenosis site were noted in our two patient groups. All patients underwent interventional bronchoscopy procedures as the first-line, and frequently the only treatment approach.

Argatroban therapy for heparin-induced thrombocytopenia in acutely ill patients.

Heparin-induced thrombocytopenia (HIT) is a prothrombotic, immune-mediated adverse reaction to heparin therapy. To evaluate clinical outcomes and effects of argatroban therapy in acutely ill HIT patients. Retrospective analysis. Hospital in-patient. Acutely ill patients with clinically diagnosed HIT from previous multicenter, historically controlled studies of argatroban therapy in HIT. Argatroban, adjusted to maintain activated partial thromboplastin times 1.5 to 3 times baseline, or historical control therapy (ie, no direct thrombin inhibition). We identified 488 patients who received argatroban (N = 390; mean dose of 1.9 microg/kg/min for a mean 6 days) or historical control therapy (N = 98) for HIT. The primary all-cause composite endpoint of death, amputation, or new thrombosis within 37 days occurred in 133 (34.1%) argatroban-treated patients and 38 (38.8%) controls (P = .41). Argatroban, versus control, significantly reduced the primary thrombosis-related composite endpoint of death because of thrombosis, amputation secondary to ischemic complications of HIT, or new thrombosis (17.7% vs 30.6%, P = .007). Significant reductions also occurred in new thrombosis and death because of thrombosis. Major bleeding was similar between groups (7.7% vs 8.2%; P = .84). Adverse outcomes were more likely to occur in patients who were initially diagnosed with HIT and thrombosis, had undergone cardiac surgery, were not white, or had more severe thrombocytopenia. In acutely ill HIT patients, argatroban, versus historical control, provides effective antithrombotic therapy without increasing major bleeding. Patients with more severe thrombocytopenia or HIT-related thrombosis on HIT diagnosis have a poorer prognosis, emphasizing the importance of prompt recognition/ treatment of HIT in acutely ill patients.

A novel cause of community-acquired pneumonia in a young immunocompetent host.

Diffuse pulmonary infiltrates represent a common problem encountered by pulmonologists. The differential diagnosis is extensive and includes infectious, inflammatory, environmental and malignant conditions. Appropriate evaluation, aside from a thorough history and physical examination, includes serologic, radiographic and procedural elements. We describe a case of a healthy male with diffuse pulmonary infiltrates. Work up revealed a novel infectious etiology. Although this particular microorganism has been described to cause native valve endocarditis, recurrent breast abscesses, osteomyelitis and bacteremia, it has to date not been described as a cause for community acquired pneumonia in immunocompetent hosts.

Lung volume reduction surgery: a meta-analysis of randomized clinical trials.

BACKGROUND: Observational studies have suggested that lung volume reduction surgery (LVRS) is superior to optimal medical therapy for selected subsets of patients with advanced emphysema. Randomized clinical trials (RCTs) with the exception of the National Emphysema Treatment Trial (NETT), failed to enroll a sufficient number of patients to provide clinicians and patients with convincing outcome data on the usefulness of LVRS. It was postulated that a meta-analysis of these RCTs (3-12 months' follow up) may provide more compelling information on the value of LVRS in patients with emphysema. METHODS: A comprehensive search of the MEDLINE database between January 1994 and January 2004 for RCTs on LVRS was performed. RESULTS: From a total of eight RCTs on record, six studies (306 patients) with 3- to 12-month follow up were deemed suitable for meta-analysis. Key baseline features of these RCT populations included heterogeneous emphysema, comparable inclusion/exclusion criteria and, in retrospect, low walking capacity as measured by the 6-minute walk distance (6MWD). This profile closely resembles NETT's 'predominantly upper lobe--low exercise tolerance emphysema' cohort. The LVRS arm of the meta-analysis population showed better results than the medical cohort in terms of pulmonary function (FEV(1) p < 0.0001, FVC p < 0.0001, residual volume p < 0.0001, total lung capacity p = 0.004), gas exchange (arterial partial pressure of oxygen p < 0.0001) and exercise capacity (6MWD p = 0.0002). Although information on quality-of-life measures was not sufficiently uniform to qualify for meta-analysis, a survey of available data revealed better results in the surgical than in the medical arms of each RCT. Mortality 6-12 months after random assignment to treatment was similar in the two study arms, suggesting that the operative mortality from LVRS was offset, within months, by deaths in the medical arm. CONCLUSIONS: This meta-analysis showed that a selected subset of patients with advanced, heterogeneous emphysema and low exercise tolerance (6MWD) experienced better outcomes from LVRS than from medical therapy.

Power of outcome measurements to detect clinically significant changes in pulmonary rehabilitation of patients with COPD.

STUDY OBJECTIVES: Several validated instruments are used to measure outcomes, such as exercise performance, dyspnea, and health-related quality of life after pulmonary rehabilitation (PR) in patients with COPD. However, no study has simultaneously compared the responsiveness of the most frequently used outcome measurements after PR. We designed this study to investigate the capacity of several of the most frequently used outcome measurements to detect changes after PR in a population of patients with severe COPD who qualified for lung volume reduction surgery. DESIGN, PATIENTS, AND INTERVENTIONS: We evaluated 37 patients with severe COPD (FEV(1) < 40%) before and after 6 to 8 weeks of outpatient PR. The following frequently used tools were evaluated: the 6-min walk distance (6MWD); functional dyspnea with the Medical Research Council (MRC) scale; baseline and transitional dyspnea index (BDI/TDI); resting and 6MWD visual analog scale (VAS); quality of life with a generic tool (the Short Form-36 [SF-36]); and two disease-specific tools, the Chronic Respiratory Disease Questionnaire (CRQ) and the St. George's Respiratory Questionnaire (SGRQ). RESULTS: After PR, mean +/- SD 6MWD increased in 33 of 37 patients (89%), from 285 +/- 97 to 343 +/- 92 m (p = 0.009). Improvements were seen also in the MRC scale in 23 of 37 patients (62%; from 2.27 +/- 0.8 to 1.86 +/- 0.6; p = 0.01); in CRQ dyspnea in 25 of 37 patients (67%; from 3.25 +/- 0.9 to 3.90 +/- 1.4; p = 0.02); in CRQ mastery in 22 of 37 patients (60%; from 4.37 +/- 1.4 to 5.14 +/- 1.3; p = 0.01); and in BDI/TDI functional in 24 of 37 patients (64%; from 1.4 +/- 0.8 to 0.7 +/- 1.1; p = 0.002). There were smaller improvements in the SGRQ in 18 of 37 patients (48%) and in the SF-36 in 19 of 37 patients (51%), but they were not statistically significant. There were good correlations between the dyspnea components of all the tools. The 6MWD change did not correlate with the changes in the other outcomes. Clinically significant changes in the values for those outcome tools were detected in > 50% of patients for the BDI/TDI, 29% of patients for the MRC scale, in 37% of patients for the 6MWD, in 48% of patients for the VAS at peak exercise, in > 50% of patients for the CRQ, and in 40% of patients for the SGRQ. CONCLUSIONS: We conclude that the VAS peak exercise, BDI/TDI, and CRQ adequately reflect the beneficial effects of PR. The 6MWD evaluates a unique domain not related to quality of life. Due to their simplicity and sensitivity, VAS at peak exercise, 6MWD, and CRQ may be the best practical tools to evaluate responsiveness to PR.

Endotracheal tubes.

A variety of different endotracheal tubes are available for distinct purposes, though the majority of patients will be well served with the standard single-lumen endotracheal tube. Specialized endotracheal tubes have been developed to aid in specific situations and novel tubes continue to be evaluated as clinicians strive for improved outcomes in various clinical conditions. Ultimately, the choice of an endotracheal tube depends on the purpose it is intended to serve.

Co-administration of furosemide with albumin for overcoming diuretic resistance in patients with hypoalbuminemia: a meta-analysis.

PURPOSE: To systematically review clinical studies of co-administration of albumin and loop diuretics in hypoalbuminemic patients as a strategy to overcome diuretic resistance. MATERIALS AND METHODS: Systematic search of electronic databases up to October 2012. We included randomized clinical trials of adults with hypoalbuminemia, comparing co-administration of loop diuretics and albumin versus loop diuretics alone. Quantitative data were synthesized with meta-analytic techniques for clinical, surrogate (urinary volume and urinary sodium excretion) and intermediate (pharmacokinetic and hemodynamic parameters) outcomes. RESULTS: Ten studies were included, of which 8 trials with crossover design were synthesized with meta-analysis. A statistically significant increase in the amount of urine volume (increment of 231 mL [95% confidence interval 135.5-326.5]) and sodium excreted (15.9 mEq [4.9-26.8]) at 8 hours were found in favor of co-administration of albumin and furosemide. These differences were no longer statistically significant at 24 hours. Meta-analyses for intermediate outcomes (ie, furosemide excretion, distribution volume etc.) did not reveal statistically significant differences. CONCLUSIONS: Synthesis of a heterogeneous body of evidence shows transient effects of modest clinical significance for co-administration of albumin with furosemide in hypoalbuminemic patients. Pragmatic, large-scale randomized studies are needed to delineate the role of this strategy.

Appendicectomy: who performs it, when and how?

A comparative review of changing patterns between 1997 and 2002 of who performs appendicectomy and a snapshot of the surgical approaches in use. It also indicates the stage at which competency in appendicectomy may be achieved by contemporary trainees in surgery and anaesthesia.

Guidelines on critical care services and personnel: Recommendations based on a system of categorization of three levels of care.

OBJECTIVES: To describe three levels of hospital-based critical care centers to optimally match services and personnel with community needs, and to recommend essential intensive care unit services and personnel for each critical care level. PARTICIPANTS: A multidisciplinary writing panel of professionals with expertise in the clinical practice of critical care medicine working under the direction of the American College of Critical Care Medicine (ACCM). DATA SOURCES AND SYNTHESIS: Relevant medical literature was accessed through a systematic Medline search and synthesized by the ACCM writing panel, a multidisciplinary group of critical care experts. Consensus for the final written document was reached through collaboration in meetings and through electronic communication modalities. Literature cited included previously written guidelines from the ACCM, published expert opinion and statements from official organizations, published review articles, and nonrandomized, historical cohort investigations. With this background, the ACCM writing panel described a three-tiered system of intensive care units determined by service-based criteria. CONCLUSIONS: Guidelines for optimal intensive care unit services and personnel for hospitals with varying resources will facilitate both local and regional delivery of consistent and excellent care to critically ill patients.
