Assess the efficacy of staged interventions aimed to reduce inappropriate Clostridioides difficile testing and hospital-onset C. difficile infection (HO-CDI) rates.
Design:
Interrupted time series.
Setting:
Community-based.
Methods/Interventions:
National Healthcare Safety Network (NHSN) C. difficile metrics from January 2019 to November 2022 were analyzed after three interventions at a community-based healthcare system. Interventions included: (1) an electronic medical record (EMR) based hard stop requiring confirming ≥3 loose or liquid stools over 24 h, (2) an infectious diseases (ID) review and approval of testing >3 days of hospital admission, and (3) an infection control practitioner (ICP) reviews combined with switching to a reverse two-tiered clinical testing algorithm.
Results:
After all interventions, the number of C. difficile tests per 1,000 patient-days (PD) and HO-CDI cases per 10,000 PD decreased from 20.53 to 6.92 and 9.80 to 0.20, respectively. The EMR hard stop resulted in a (28%) reduction in the CDI testing rate (adjusted incidence rate ratio ((aIRR): 0.72; 95% confidence interval [CI], 0.53 to 0.96)) and ID review resulted in a (42%) reduction in the CDI testing rate (aIRR: 0.58; 95% CI, 0.42–0.79). Changing to the reverse testing algorithm reduced reported HO-CDI rate by (95%) (cIRR: 0.05; 95% CI; 0.01–0.40).
Conclusions:
Staged interventions aimed at improving diagnostic stewardship were effective in overall reducing CDI testing in a community healthcare system.
To assess the impact of treatment guidelines on the trends of outpatient antibiotic prescription among pediatric and adult patients at a cancer center in Pakistan.
Design:
Retrospective observational study conducted between July 1st 2018 and July 31st 2023.
Methods:
We determined the indication for antibiotics and the frequency of guideline-discordant prescriptions for upper respiratory tract infection (URTI), lower respiratory tract infection (LRTI), urinary tract infection (UTI), and diarrhea. The χ2 test was used to assess the impact of treatment guidelines on antibiotics prescribed for these indications.
Results:
The top indications for antibiotic prescription were skin and skin structure infection (SSSI) (n = 5159; 21.5%), URTI (n = 2760; 11.5%) and UTI (n = 2686; 11.2%). Amoxicillin-clavulanate (n = 7964; 33.3%), was the most frequently prescribed antibiotic. A large proportion of antibiotic prescriptions for URTI, diarrhea, UTI, and LRTI were either inappropriate (n = 6695; 86.5%) or unnecessary (n = 5534; 71.5%). Results revealed a statistically significant decline in the proportion of inappropriate antibiotics for UTI (91.3% vs 84.0%; P ≤ .001) and diarrhea (92.6% vs 87.0%; P = .031) and unnecessary antibiotics for diarrhea (90.2% vs 83.2%; P = .016) with the introduction of treatment guidelines. We noted a higher proportion of unnecessary prescriptions for LRTI (41.7% vs 31.7%; P = .003) and inappropriate antibiotics for UTI (95.1% vs 87.4%; P = .011) for pediatric patients.
Conclusion:
Misuse of outpatient antibiotics is common. Diarrhea, URTI, UTI, and LRTI are high-priority conditions for outpatient oncology-focused prescriber education and stewardship interventions.
An (ongoing) interrogation of colonial wrongdoing is important for debates on decolonisation, restorative justice, racial and gender equality and global political and socio-economic equality. This article presents a theoretical study of colonialism’s legal-political injustices and aims to (re)turn the discussion on colonialism to the field’s most powerful insight, i.e. that of of epistemic violence and injustice. This article also suggests that the reach of this historical injustice went much further than the politics of autonomy, usurpation of territorial rights, political disenfranchisement and resource appropriation. To address the question of colonialism’s distinctiveness as a political mission, which has been discussed in recent debates within analytic philosophy, it argues that colonialism’s epistemic injustice, which denied the very existence and the traditions of the colonised, is the foundational and distinctive feature of colonialism as a political system and which drives its continued impact to this day.
In this article, I reconceptualise the League of Nations as an Imperial Assemblage that embeds and is embedded by coloniality. Relying on the return to the League’s historisisation by Third World Approaches to International Law, I argue that we can understand the League as a governance body that works across scales of international, transnational and local actors, processes and structures to reiterate coloniality within the mandated territories. I utilise Deleuzian notions of assemblage alongside the concept of ‘coloniality’ within the literature of decolonial theory within International Relations and Sociology to show how the work of the League’s various actors, processes and structures across different scales made, actualised and evolved the laws on Forced Labour and Slavery from 1925 to 1932 in the inter-war era with a particular focus on Mandate Territories B and C.
• Study current practices in Old Age Psychiatry (OAP) wards regarding Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) documentation.
• Create an intervention to improve compliance with Scottish Government guidance.
Hypothesis:
• An intervention could improve likely inconsistencies in current DNACPR practices.
Background: DNACPR forms are a contentious issue in the media, impacting patients and families’ views. The Scottish Government's ‘Cardiopulmonary resuscitation decisions – integrated adult policy: guidance’ from 2016 seeks to prevent inappropriate attempts at CPR and subsequent distress to patients and families. It makes various recommendations for clinicians when making these decisions and completing DNACPR forms.
Methods
This was a two-cycle retrospective audit utilising physical and electronic notes for all patients across two OAP wards at the Vale of Leven Hospital, Alexandria. Data were collected on demographics, presence and adequacy of DNACPR forms based on Scottish Government guidance. Between the first (12/09/22) and second (25/11/22) cycle, a poster to aid DNACPR decisions and documentation was created and displayed in the ward office.
Results
There were a total of 13 patients in cycle 1 and 14 patients in cycle 2. The number of patients with forms increased from 3 to 8 between cycles (including all those with organic diagnoses in cycle 2). Between cycle 1 and 2, there were improvements in the proportion of forms: completed at admission (66.7% to 87.5%, respectively), correctly filed (66.7% to 100%), with review timeframes specified (0% to 62.5%) and consultant signatures (33.3% to 100%). The mean age of patients with DNACPR forms was higher than those without forms in both cycles (86.7 and 85.7 in cycle 1 respectively versus 77.9 and 77.7 in cycle 2). The mean number of comorbidities did not vary significantly between those with and without forms or between cycles.
Conclusion
The project revealed various shortcomings in DNACPR practices across both wards. The creation of a poster intervention helped to improve DNACPR practices and compliance with Scottish Government guidance. Despite this, notable areas for improvement still remain. Incorporating these new practices into hospital policy alongside more audit cycles could aid further progress in outstanding areas for improvement.
Changes in flight stability characteristics at the advanced stage of aircraft design are complex and require thorough investigations. This paper examines the impact of wing strake modification on high-performance aircraft using computational fluid dynamics (CFD). The dynamic behaviour is calculated using the forced oscillation technique, while the effect of geometric variation on longitudinal stability characteristics is extensively studied. Steady-state experimental data is utilised to validate the computational setup. Static aerodynamic coefficients, dynamic stability derivatives and the positions of aerodynamic and pressure centres are employed to quantify the changes. Furthermore, the alterations in stability characteristics are correlated with flow physics. The results indicate a reduction in longitudinal static and dynamic stability at various flight conditions due to the proposed modification. This deliberate reduction was necessary to accommodate the installation of a fly-by-wire system. The discussed design changes have been effectively implemented on an in-service aircraft.
Brain tumors in adults and children range from devastating malignant tumors with a dire prognosis to benign tumors that can be totally resected with a favorable outcome. The incidence rate for primary brain tumors in adults in the United States is approximately 23.8 per 100,000 persons. Of those, approximately two thirds are benign or borderline in nature. The most common benign tumor in adults is meningioma. The incidence in the pediatric population is approximately 6.1 per 100,000 children. However, the incidence of malignant brain tumors is higher in children than adults. We discuss the most common benign brain tumors in adults followed by a discussion on pediatric brain tumors.
The International Federation of Medical and Biological Engineering created a multidisciplinary working group to discuss assessments of artificial intelligence and machine learning (AI/ML) applications in health care. Engineers, clinicians, and economists identified evidence generation as a critical topic. Heart failure (HF) was selected to investigate the available evidence on the clinical effectiveness and safety of AI/ML applications. Attention was paid to transparency of AI/ML methods and their data sources.
Methods
A scoping review was conducted on AI/ML algorithms developed for the management of HF. A search for systematic reviews, scoping reviews, and meta-analyses published from 1976 to October 2022 was conducted in Embase, MEDLINE, and Scopus.
Results
Of 456 relevant publications, 21 papers were included in the final analysis. Most papers (10 systematic reviews, five meta-analyses, and six non-systematic or scoping reviews) included studies conducted in North America. No study was conducted in Africa. The healthcare setting was not clearly stated in approximately half of the studies. A lack of agreement was noticed regarding the quality assessment tools used among the reviews. The most common data source for AI/ML algorithms was electronic health records, but in some cases data sources were not reported. While deep learning emerged as the most common adopted methodology, covariates were not always included in the algorithm development. The review demonstrated that comparative assessment of algorithms requires further investigation, given the high variability in the comparator used (e.g., clinical gold standard, other AI/ML algorithms, or other statistical methods). The main investigated endpoints were the incidence of HF and the number of hospital admissions.
Conclusions
When assessing innovative health technologies such as AI/ML applications in health care, evidence is among the main challenges. Our scoping review, focusing on algorithms developed to manage HF, showed that the biggest challenges relate to the quality of the studies, the adoption of a comparative approach, and transparency of methods.
A comparison of the modelling methodologies to capture the damage onset and delamination initiation in Abaqus and LS-Dyna is presented. A quasi-isotropic carbon fibre reinforced polymer laminate is modelled under a low-energy impact scenario. Hashin, Puck and Cuntze criteria are implemented for assessing intra-laminar damage in Abaqus in the linear elastic regime without damage evolution, with Virtual Crack Closure Technique being used for inter-laminar failure. In LS-Dyna, the Chang-Chang criterion is used for the intra-lamina failure with damage evolution, whereas delamination is captured using cohesive zone model and the tiebreak contact algorithm. The implementations carried out by both finite element software result in a modelling work well set to analyse and predict the impact response at the initial stages of delamination and damage within the plies. The composite damage criteria used in both finite element codes overall predict stiffer results when compared with the experimental data, however, remain in close agreement with each other.
Automatic paraphrase detection is the task of measuring the semantic overlap between two given texts. A major hurdle in the development and evaluation of paraphrase detection approaches, particularly for South Asian languages like Urdu, is the inadequacy of standard evaluation resources. The very few available paraphrased corpora for these languages are manually created. As a result, they are constrained to smaller sizes and are not very feasible to evaluate mainstream data-driven and deep neural networks (DNNs)-based approaches. Consequently, there is a need to develop semi- or fully automated corpus generation approaches for the resource-scarce languages. There is currently no semi- or fully automatically generated sentence-level Urdu paraphrase corpus. Moreover, no study is available to localize and compare approaches for Urdu paraphrase detection that focus on various mainstream deep neural architectures and pretrained language models.
This research study addresses this problem by presenting a semi-automatic pipeline for generating paraphrased corpora for Urdu. It also presents a corpus that is generated using the proposed approach. This corpus contains 3147 semi-automatically extracted Urdu sentence pairs that are manually tagged as paraphrased (854) and non-paraphrased (2293). Finally, this paper proposes two novel approaches based on DNNs for the task of paraphrase detection in Urdu text. These are Word Embeddings n-gram Overlap (henceforth called WENGO), and a modified approach, Deep Text Reuse and Paraphrase Plagiarism Detection (henceforth called D-TRAPPD). Both of these approaches have been evaluated on two related tasks: (i) paraphrase detection, and (ii) text reuse and plagiarism detection. The results from these evaluations revealed that D-TRAPPD ($F_1 = 96.80$ for paraphrase detection and $F_1 = 88.90$ for text reuse and plagiarism detection) outperformed WENGO ($F_1 = 81.64$ for paraphrase detection and $F_1 = 61.19$ for text reuse and plagiarism detection) as well as other state-of-the-art approaches for these two tasks. The corpus, models, and our implementations have been made available as free to download for the research community.
The sharp bound for the third Hankel determinant for the coefficients of the inverse function of convex functions is obtained, thus answering a recent conjecture concerning invariance of coefficient functionals for convex functions.
The Health Information and Quality Authority (HIQA) Tallaght Report of 2012 found care of lodged admitted patients on ED trolleys was undermined in terms of quality and safety. HIQA advised the practice of lodging in ED adjacent hospital corridors should be discontinued entirely. This message was reiterated during the pandemic. Some lodged patients may spend the total duration of their admission on an ED trolley. ED has 15 Adult rooms, seven pediatric rooms, two minor injury rooms, one procedure room and two resus bays. The aim was to calculate the annual number of days when no admitted patients were lodged on trolleys in ED.
Method:
A descriptive study using data available from nationally issued reports on patients allocated to trolleys to the ED of Wexford General Hospital from January 2019-September 2022. Data was collected from national HSE daily SBAR reports. “Lodged patients” were those present in ED admitted but for whom no ward bed existed at 0745 daily.
Results:
Data was collected for 1,369 days, 90 days were excluded due to missing data sets, and data were included for 1,279 days. 290 days were recorded in 2019 with no lodged patients, 126 in 2020, 55 in 2021, and only 11 days in 2022 with no lodged patients. In 2022 the average number of lodged patients was six (Range 0-19). A total of 47 days had a lodged count of ten or greater.
Conclusion:
Despite a strong recommendation from HIQA to terminate the practice of ED patient lodging, this has not been implemented. During the COVID-19 pandemic, there had been a reduction in the overall number of patients visiting the ED. This contributed to the reduction in trolley-lodged patients however post-COVID pandemic there has been a surge in attendance with a clear deficit in bed capacity.
Trauma is one of the leading causes of death in patients under 40 years of age. The Advanced Trauma Life Support (ATLS) Guidelines are widely accepted as the standardized approach to trauma and classify hemorrhagic shock according to heart rate (HR), blood pressure (BP), urinary output, and mental status. Paradoxical bradycardia (defined as HR <60 bpm) in hemorrhagic shock is an uncommon presenting feature and presents a diagnostic challenge to the physician; its true incidence is unknown.
Method:
A case of paradoxical bradycardia was examined as a presenting feature in hemorrhagic shock.
Results:
A 17-year-old male patient presented to our Emergency Department (ED) with collapse and abdominal pain following a collision with another player during a sports match.
The patient was hypotensive (BP 92/42) and bradycardic at triage, with a heart rate of 50. He was pale and diaphoretic with a Glasgow Coma Scale of 13/15, thready pulses, and localized peritonitis in the left upper quadrant of his abdomen.
An increase in blood pressure was observed following initial fluid resuscitation; however, this was transient and preceded the onset of profound hypotension (BP 64/30). Bradycardia with a heart rate between 50-60bpm was persistent despite resuscitative efforts.
Abdominal ultrasound demonstrated intraperitoneal free-fluid, and Computerized Tomography confirmed the presence of a grade V splenic laceration. He was taken to the operating theater for emergency laparotomy and underwent splenectomy. A 2.3 liter hemoperitoneum was found intraoperatively. There were no further complications post-operatively, and he made a full recovery.
Conclusion:
Tachycardia is a potentially unreliable marker of blood loss, especially in young, healthy patients. A high index of suspicion is necessary to prevent this uncommon but life-threatening feature of hemorrhagic shock from being overlooked.
Abstract If the formal transfer of power in August 1947 was an occasion of profound optimism in India and Pakistan, it was also accompanied by the dissatisfaction of those who felt betrayed by freedom. Blurring the lines between national and international and revealing the persistent influence of transnational ideological and mobilizational networks, this chapter traces the emergence of culture as a key battleground between the Pakistani state and its progressive critics throughout the 1950s and 1960s. Literature, poetry, music, film, and art were central to this seemingly cosmic battle between ideologies and world systems, and Pakistani communists and progressives of the time envisioned their politics in both national and international terms. In much the same way, culture was an extremely significant sphere for societal reform for the left's ideological opponents and state authorities, particularly in the context of a global Cold War in which Pakistan was the United States’ key regional ally.
Key words: Pakistan, communism, culture, Cold War, decolonization
In 1952, the Criminal Investigation Department of Punjab published two volumes titled, The Communist Party of West Pakistan in Action. Pakistani communists, it claimed, had built “a powerful party machine” out of the devastation of Partition. Migrant communists from India had succeeded in reviving a party decimated by the chaos, forced migration, and massacres that accompanied independence in 1947. Pakistan was left with a depleted communist base in poor financial shape. Nevertheless, the report's authors claimed, Pakistani communists were now fomenting a conspiracy to overthrow the government.
But more than the party or its ill-fated 1951 conspiracy, it was international communism itself that posed the biggest threat to Pakistan. Communism, the report declared, was “the most inexorable and momentous political force in the contemporary world.” Its “strength and potentialities (were) often under-estimated,” especially in Pakistan where this complacency was partly drawn from the belief that communism and Islam were “incompatible.” And yet, as the increasing influence of communism in one Muslim society after another attested to – in Malaya, Afghanistan, Iran, and Egypt – the Communist Party and its affiliates could not be underestimated. Their “insidious” techniques, “fanatical zeal,” and “single mindedness of purpose” meant that communism would continue to be a dangerous adversary.
The Communist Party of Pakistan was formally banned in 1954, but the danger its ideas posed remained a source of concern, anxiety, and paranoia for decades to come.
Understanding the reasons for the yield gap between potential and actual yield can provide insights for enhancing canola production by adapting measures for ensuring food security. The canola yield gap under different management practices (e.g. water, nitrogen, N- and sowing dates) was quantified using research trials that were conducted at on-station and historical data (1980–2016) and the CROPGRO-Canola model for Punjab, Pakistan. The integrated approach revealed that low inputs of N, the amount of irrigation, sowing date and the use of seeds from home stocks were the principal causes for a low yield. The CROPGRO-Canola model was able to simulate the canola yield from research trials (R2 = >0.90) and farm survey data (R2 = 0.63). The average yield gap between potential (YP), N-limited (YNL), water-limited (YWL), N- and water-limited (YNWL), and overall farmer field yield (YOFF) was 50, 46, 62 and 72%, respectively. The yield-gap with achievable yield (YA) for YNL, YWL, YNWL and YOFF was 34, 28, 49 and 63%, respectively. Overall, the results showed that a high canola yield for farmers’ fields can be obtained by selecting appropriate varieties and sowing dates with N rate of 120 kg/ha and efficient irrigation management. However, further studies are necessary to fully comprehend the underlying causes for the low actual yield and the high yield variability of farmers’ fields.
Pompe disease (PD) is a rare, progressive neuromuscular disease that severely affects motor and respiratory functions. Late onset PD (LOPD) is the most common phenotype. Current treatment involves enzyme replacement therapy (ERT) with alglucosidase alfa, which was first approved in 2006. In Europe, the treatment landscape is changing as two new ERTs have been filed for regulatory approval: avalglucosidase alfa and cipaglucosidase alfa plus miglustat. We analyzed how health technology assessment (HTA) and reimbursement criteria may be applied to ERTs in key countries for patients with PD.
Methods
Eighteen different factors were identified from the pivotal trials (LOTS, COMET, and PROPEL) for the three recombinant enzymes. These covered the categories of trial design, endpoints, quality of life, and other product characteristics. Twenty-six HTA experts and health economists from Denmark, England, France, Germany, Italy, the Netherlands, Spain, and Sweden with rare disease experience were interviewed during the period from July to September 2021. In structured discussions, each participant was asked to rate (from one to seven) the factors in terms of their importance and impact on the HTA evaluation and reimbursement of treatments for adults with PD.
Results
The following factors were highly rated: a well-defined PD trial population; use of an active trial comparator; efficacy in both treatment naïve and experienced subpopulations; a superiority study design; and payer-relevant endpoints and quality of life improvements. The five lowest rated factors were open-label data, biomarkers, innovation, ease of administration, and mode of action. While the results were mostly consistent across countries, the HTA expert viewpoints varied depending on the country. For example, HTA experts in Italy, the Netherlands, and Sweden rated innovation and biomarkers more highly than German experts.
Conclusions
As new ERTs become licensed, achieving reimbursement and successful HTA of them will require a clear exposition of payer-relevant evidence for the LOPD population in the target country, including comparative randomized controlled trial data, benefits for experienced and treatment naïve subgroups, and payer-relevant endpoints and quality of life gains.
This chapter traces the journey of Abdullah Malik, a noted writer, journalist, and communist from Pakistan, to the Cultural Congress of Havana in 1968. Through Malik’s account, this chapter ties the Havana Congress to larger debates around culture, socialism, and freedom in Pakistan during the Cold War. In doing so, it documents the significance of international conferences and congresses for progressives given the tense battle of ideas in Pakistan. In that sense, the Havana Congress was not simply an isolated event organized at the behest of Cuba’s revolutionary government. Instead, it was emblematic of a post-Bandung world in which debates over culture, politics, and the future of the Third World were central to the worldview and imagination of progressive intellectuals, writers, artists, and poets.
Keywords: Cold War, Third Worldism, Pakistan, Cuba, progressive writers
For a week in January 1968, socialists from across the world convened in Cuba for the first Cultural Congress of Havana. The Congress was described by one delegate as an ‘international conference’ for ‘enlightened and independent thinkers, communist writers, journalists, artists, scientists, doctors and religious divines’. With over 400 delegates from more than 70 countries in Asia, Africa and the Americas, the purpose of this august assembly was to raise a rallying cry against imperialism, and more specifically, American imperialism. Its more immediate concern, however, was to deliberate upon ways in which the ‘malign’ cultural influence of (American) Imperialism could be combatted. The attending delegates made passionate appeals to their fellow intellectuals, artists, and writers across the Third World to combat the pernicious and reactionary cultural influence of the United States and the grotesque role it had played in retarding the development of their arts and literature. Third World intellectuals were also asked to lend their support to the heroic struggle of the Vietnamese people against American imperialism. After a week of intense and fractious debates, the conference eventually concluded with a fiery two-hour speech by Fidel Castro who declared the conference, ‘the first of its type’, an unqualified success.
Castro was, however, only half correct. The Congress was certainly the first of its kind to be convened in Havana. It was also, Castro claimed, unique in terms of the diversity of its representation and the unanimity expressed by its delegates against the ‘universal enemy’ of mankind: ‘Yankee Imperialism’.
To determine the mental impact the second wave of COVID-19 has had on health care professionals working in the National Health Services (NHS), United Kingdom.
Methods
A cross-sectional descriptive web-based survey was conducted among the staff of National Health Services (NHS) in Poole, United Kingdom. Two tertiary care hospitals staff were part of this study. The study was spanned over a duration of 6 months, October 2020 to April 2021. A standard GAD-7 and PHQ-9 questionnaire along with demographic information was uploaded on google docs for data collection. All healthcare staff working in the hospitals were included. Any person that did not fill the questionnaire completely was excluded. Data collected were analysed using SPSS for descriptive statistics and the chi-squared test was done keeping p < 0.05 as significant.
Results
A total of 160 health care professionals took part in the survey, with a mean age of 37.36 (SD = 11.51) years, predominantly females (58.8%). The majority of participants were not depressed (78.1%, p = 0.004) nor were they anxious (85%, p = 0.008). A significant difference (p = 0.050) was seen in participant's anxiousness regarding the source of information. All other demographic parameters were not significant for differences in depression or anxiety (p > 0.05). 33.6% of the respondents agreed and 9.6% totally agreed to being terrified of contracting the coronavirus. 40.4% disagreed while 16% did not have an opinion. A similar trend was seen for the other statements. More than half (56.3% and 56.9%) of the participants answered in the affirmative that they were worried about contracting the disease and getting their living place contaminated, a staggering 91.3% were anxious about affecting their families.
Conclusion
The second wave of COVID-19 has had minimal effect on the mental health of health care workers in the NHS.
