Dramatic Copyright in Australia to 1912

Australian colonial playwrights had great difficulty protecting their work from unauthorised theatrical productions. The whole question of the legal defence of dramatic creative effort was uncertain. Dramatists in colonial Australasia often sold their scripts outright to theatrical managers, and managers, instead of relying on copyright protection, attempted to restrict the making of copies

A Geographically Weighted Regression Analysis of General Election Turnout in the Republic of Ireland

Turnout in the 2002 general election confirm e d a downwar d trend in Irish voter pa rticipation levels, that first becam e evident in the early 1980s and was to culm inate in th e lowest turnout fo r an Irish general election since the foundation of the st ate (Figure 1). Given this context, voter turnout is a topic that requires further analysis within the Irish con t ex t, and two ap proaches to address i ng this top i c ex ists, with each approach having its own distin ctive adv a ntages and dis a dvantages. The surveying approach draws on individual-level data, and has the ad vantage of being able to draw on a wide range of variables, including social-psychological variables, an d m a ke direct inferences about the behaviour, and sources of the behaviour, of individuals. However, questionnaire surveys generally te nd to overestim ate turnout levels, with poten tial bias in su rvey re spon se rates resu lting in the under-rep res e ntation of non-voters in survey sam p les. The second type of data – aggregate data – is subject to problem s arising from the lim ited range of variables that can be accessed in seeking explanations of low turnout (u sually lim ited to data that can be drawn from census analyses) and the cross-lev e l infere nce problem that arises in any attem p t to m a ke inferences about individual-leve l behaviour from aggregate-leve l data (Achen and Shively, 1995). However, the big advantage of aggregate data lies in th e accuracy of the estim a tion of the dependent variable (turnout) and in the potential it offers for spatial and censu s-based analysis of variations in the turnout variable. Lower levels of aggregation allow fo r a larger num ber of cases to be analysed and for more detailed pictures of spatial varia tions in turnout leve ls to be gleaned

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.This guideline is written primarily for doctors and nurses working in dialysis units and related areas of medicine in the UK, and is an update of a previous version written in 2009. It aims to provide guidance on how to look after patients and how to run dialysis units, and provides standards which units should in general aim to achieve. We would not advise patients to interpret the guideline as a rulebook, but perhaps to answer the question: "what does good quality haemodialysis look like?"The guideline is split into sections: each begins with a few statements which are graded by strength (1 is a firm recommendation, 2 is more like a sensible suggestion), and the type of research available to back up the statement, ranging from A (good quality trials so we are pretty sure this is right) to D (more like the opinion of experts than known for sure). After the statements there is a short summary explaining why we think this, often including a discussion of some of the most helpful research. There is then a list of the most important medical articles so that you can read further if you want to - most of this is freely available online, at least in summary form.A few notes on the individual sections: 1. This section is about how much dialysis a patient should have. The effectiveness of dialysis varies between patients because of differences in body size and age etc., so different people need different amounts, and this section gives guidance on what defines "enough" dialysis and how to make sure each person is getting that. Quite a bit of this section is very technical, for example, the term "eKt/V" is often used: this is a calculation based on blood tests before and after dialysis, which measures the effectiveness of a single dialysis session in a particular patient. 2. This section deals with "non-standard" dialysis, which basically means anything other than 3 times per week. For example, a few people need 4 or more sessions per week to keep healthy, and some people are fine with only 2 sessions per week - this is usually people who are older, or those who have only just started dialysis. Special considerations for children and pregnant patients are also covered here. 3. This section deals with membranes (the type of "filter" used in the dialysis machine) and "HDF" (haemodiafiltration) which is a more complex kind of dialysis which some doctors think is better. Studies are still being done, but at the moment we think it's as good as but not better than regular dialysis. 4. This section deals with fluid removal during dialysis sessions: how to remove enough fluid without causing cramps and low blood pressure. Amongst other recommendations we advise close collaboration with patients over this. 5. This section deals with dialysate, which is the fluid used to "pull" toxins out of the blood (it is sometimes called the "bath"). The level of things like potassium in the dialysate is important, otherwise too much or too little may be removed. There is a section on dialysate buffer (bicarbonate) and also a section on phosphate, which occasionally needs to be added into the dialysate. 6. This section is about anticoagulation (blood thinning) which is needed to stop the circuit from clotting, but sometimes causes side effects. 7. This section is about certain safety aspects of dialysis, not seeking to replace well-established local protocols, but focussing on just a few where we thought some national-level guidance would be useful. 8. This section draws together a few aspects of dialysis which don't easily fit elsewhere, and which impact on how dialysis feels to patients, rather than the medical outcome, though of course these are linked. This is where home haemodialysis and exercise are covered. There is an appendix at the end which covers a few aspects in more detail, especially the mathematical ideas. Several aspects of dialysis are not included in this guideline since they are covered elsewhere, often because they are aspects which affect non-dialysis patients too. This includes: anaemia, calcium and bone health, high blood pressure, nutrition, infection control, vascular access, transplant planning, and when dialysis should be started.Peer reviewe

Variation in centre-specific survival in patients starting renal replacement therapy in England is explained by enhanced comorbidity information from hospitalization data

Background Unadjusted survival on renal replacement therapy (RRT) varies widely from centre to centre in England. Until now, missing data on case mix have made it impossible to determine whether this variation reflects genuine differences in the quality of care. Data linkage has the capacity to reduce missing data. Methods Modelling of survival using Cox proportional hazards of data returned to the UK Renal Registry on patients starting RRT for established renal failure in England. Data on ethnicity, socioeconomic status and comorbidity were obtained by linkage to the Hospital Episode Statistics database, using data from hospitalizations prior to starting RRT. Results Patients with missing data were reduced from 61 to 4%. The prevalence of comorbid conditions was remarkably similar across centres. When centre-specific survival was compared after adjustment solely for age, survival was below the 95% limit for 6 of 46 centres. The addition of variables into the multivariable model altered the number of centres that appeared to be ‘outliers’ with worse than expected survival as follows: ethnic origin four outliers, socioeconomic status eight outliers and year of the start of RRT four outliers. The addition of a combination of 16 comorbid conditions present at the start of RRT reduced the number of centres with worse than expected survival to one. Conclusions Linked data between a national registry and hospital admission dramatically reduced missing data, and allowed us to show that nearly all the variation between English renal centres in 3-year survival on RRT was explained by demographic factors and by comorbidity

High severity of abortion complications in fragile and conflict-affected settings: a cross-sectional study in two referral hospitals in sub-Saharan Africa (AMoCo study)

BACKGROUND: Abortion-related complications are one of the five main causes of maternal mortality. However, research about abortion is very limited in fragile and conflict-affected settings. Our study aims to describe the magnitude and severity of abortion-related complications in two referral hospitals supported by Médecins Sans Frontières and located in such settings in northern Nigeria and Central African Republic (CAR). METHODS: We used a methodology similar to the World Health Organization (WHO) near-miss approach adapted in the WHO multi-country study on abortion (WHO-MCS-A). We conducted a cross-sectional study in the two hospitals providing comprehensive emergency obstetric care. We used prospective medical records' reviews of women presenting with abortion-related complications between November 2019 and July 2021. We used descriptive analysis and categorized complications into four mutually exclusive categories of increasing severity. RESULTS: We analyzed data from 520 and 548 women respectively in Nigerian and CAR hospitals. Abortion complications represented 4.2% (Nigerian hospital) and 19.9% (CAR hospital) of all pregnancy-related admissions. The severity of abortion complications was high: 103 (19.8%) and 34 (6.2%) women were classified as having severe maternal outcomes (near-miss cases and deaths), 245 (47.1%) and 244 (44.5%) potentially life-threatening, 39 (7.5%) and 93 (17.0%) moderate, and 133 (25.6%) and 177 (32.3%) mild complications, respectively in Nigerian and CAR hospitals. Severe bleeding/hemorrhage was the main type of complication in both settings (71.9% in the Nigerian hospital, 57.8% in the CAR hospital), followed by infection (18.7% in the Nigerian hospital, 27.0% in the CAR hospital). Among the 146 women (Nigerian hospital) and 231 women (CAR hospital) who did not report severe bleeding or hemorrhage before or during admission, anemia was more frequent in the Nigerian hospital (66.7%) compared to the CAR hospital (37.6%). CONCLUSION: Our data suggests high severity of abortion-related complications in these two referral facilities of fragile and conflict-affected settings. Factors that could contribute to this high severity in these contexts include greater delays in accessing post-abortion care, decreased access to contraceptive and safe abortion care that result in increased unsafe abortions; as well as increased food insecurity leading to iron-deficiencies and chronic anaemia. The results highlight the need for better access to safe abortion care, contraception, and high quality postabortion care to prevent and manage complications of abortion in fragile and conflict-affected settings

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
