Charting the future of patient care: A strategic leadership guide to harnessing the potential of artificial intelligence.

Artificial Intelligence (AI) applications have the potential to revolutionize conventional healthcare practices, creating a more efficient and patient-centred approach with improved outcomes. This guide discuses eighteen AI-based applications in clinical decision-making, precision medicine, operational efficiency, and predictive analytics, including a real-world example of AI's role in public health during the early stages of the COVID-19 pandemic. Additionally, we address ethical questions, transparency, data privacy, bias, consent, accountability, and liability, and the strategic measures that must be taken to align AI with ethical principles, legal frameworks, legacy information technology systems, and employee skills and knowledge. We emphasize the importance of informed and strategic approaches to harness AI's potential and manage its challenges. Moreover, this guide underscores the importance of evaluating and integrating new skills and competencies to navigate and use AI-based technologies in healthcare management, such as technological literacy, long-term strategic vision, change management skills, ethical decision-making, and alignment with patient needs.

Social media networks and leadership ethics in healthcare.

Social media has penetrated intrapersonal and professional communication, particularly among a younger generation of healthcare professionals and patients who have grown up in the digital age of communication. Social media tools provide a unique set of opportunities in healthcare, but with these new opportunities come a number of potential challenges. As health leaders navigate the increasingly complex world of social media, concerns have arisen regarding questions of ethics and professionalism and how the use of social media fits within the social contract between the medical profession and society. This article describes the changing parameters of professional conduct in digital environments and proposes a set of considerations and recommendations for health leaders to navigate this new frontier.

Integration of a recent infection testing algorithm into HIV surveillance in Ireland: improving HIV knowledge to target prevention.

Recent infection testing algorithms (RITA) for HIV combine serological assays with epidemiological data to determine likely recent infections, indicators of ongoing transmission. In 2016, we integrated RITA into national HIV surveillance in Ireland to better inform HIV prevention interventions. We determined the avidity index (AI) of new HIV diagnoses and linked the results with data captured in the national infectious disease reporting system. RITA classified a diagnosis as recent based on an AI < 1.5, unless epidemiological criteria (CD4 count <200 cells/mm3; viral load <400 copies/ml; the presence of AIDS-defining illness; prior antiretroviral therapy use) indicated a potential false-recent result. Of 508 diagnoses in 2016, we linked 448 (88.1%) to an avidity test result. RITA classified 12.5% of diagnoses as recent, with the highest proportion (26.3%) amongst people who inject drugs. On multivariable logistic regression recent infection was more likely with a concurrent sexually transmitted infection (aOR 2.59; 95% CI 1.04-6.45). Data were incomplete for at least one RITA criterion in 48% of cases. The study demonstrated the feasibility of integrating RITA into routine surveillance and showed some ongoing HIV transmission. To improve the interpretation of RITA, further efforts are required to improve completeness of the required epidemiological data.

Social media in colorectal surgery.

The engagement of social media in healthcare continues to expand. For members of the colorectal community, social media has already made a significant impact on practice, education and patient care. The applications are unique such that they provide a platform for instant communication and information sharing with other users worldwide. The purpose of this article is to provide an overview of how social media has the potential to change clinical practice, training, research and patient care in colorectal surgery.

Use of a geographic information system to map cases of measles in real-time during an outbreak in Dublin, Ireland, 2011.

In 2011, there was a large measles outbreak in Dublin. Nationally 285 cases were notified to the end of December 2011, and 250 (88%) were located in the Dublin region. After the first case was notified in week 6, numbers gradually increased, with 25 notified in June and a peak of 53 cases in August. Following public health intervention including a measles-mumps-rubella (MMR) vaccination campaign, no cases were reported in the Dublin region in December 2011. Most cases (82%) were children aged between 6 months and 14 years, and 46 cases (18%) were under 12 months-old. This is the first outbreak in Dublin to utilise a geographic information system for plotting measles cases on a digital map in real time. This approach, in combination with the analysis of case notifications, assisted the department of public health in demonstrating the extent of the outbreak. The digital mapping documented the evolution of two distinct clusters of 87 (35%) cases. These measles cases were infected with genotype D4-Manchester recently associated with large outbreaks across Europe. The two clusters occurred in socio-economically disadvantaged areas and were attributable to inadequate measles vaccination coverage due in part to the interruption of a school-based MMR2 vaccination programme.

Response shift in self-reported functional scores after knee microfracture for full thickness cartilage lesions.

OBJECTIVE: Our aim was to determine whether response shift (RS), a change in the internal standards of a patient, occurs in patients treated for full thickness knee cartilage defects. We have also evaluated the effect of functional scores on patient satisfaction after surgery. DESIGN: Self-administered questionnaires were used to evaluate pre- and post-operative and retrospective post-operative scores of 53 patients following knee microfracture. Patient satisfaction, Lysholm, Visual Analogue Scale (VAS) for pain and modified International Knee Documentation Committee (IKDC) scores were evaluated. RS (pre-test-then-test), unadjusted and adjusted treatment effects (UTE and ATE) and their effect sizes were calculated. RESULTS: All four functional outcome measures had a positive RS. The effect size of the RS ranged from around 0.35 for the Lysholm and IKDC2 score to over 0.9 for the VAS pain score. Gender, age, smoking status and time since follow-up did not significantly affect the RS. RS did not differ significantly between the three patient satisfaction groups (P>0.05). Post-operative Lysholm and IKDC1 scores differed most significantly between the satisfaction groups. CONCLUSIONS: All four scores had a significant shift, implying that patients thought they felt worse before the operation in retrospect than they did at the time. The traditional way of assessing treatment effect, difference between post-intervention and pre-intervention functional scores, may be confounded by change in the internal standards of the patient and should take this into account. RS did not affect the clinical interpretation in this case series. Patient-reported satisfaction after surgery is only related to post-operative scores.

Wet cement remains a poorly recognised cause of full-thickness skin burns.

In 1993 we published a paper stating that wet construction cement is a poorly recognised cause of full-thickness burns [Injury 24 (1993) 615]. Ten years since publication we re-evaluated cement burns to ascertain if there had been any changes in awareness and incidence. All cement related burns assessed at this unit were reviewed over a three and a half year period. Postal questionnaires were sent to all those affected. Cement burns accounted for 2.2% of referrals to the Burns Unit during this studied period as compared to 1% during the original study. Fifty-one percent of patients stated they were unaware of the risk of cement burns and took no precautions. Eighty-six percent of the burns involved the lower limb. Fifty-three percent of burns affected professional users. Fifty percent had full-thickness involvement with 21% requiring operation. Eighty-eight percent of patients did not notice any warnings on the cement bag or delivery docket and 95% felt warnings should be larger and more obvious. This study has shown that cement burns may have resulted from shortcomings in the information and warnings provided to customers by cement manufacturers.

Baculovirus expression of parvovirus B19 (B19V) NS1: utility in confirming recent infection.

BACKGROUND: The presence of anti-parvovirus B19 (B19V) IgM against viral capsid proteins (VP1 and VP2) has long been used to detect recent infection. The utility of antibodies directed against B19V NS1 protein has received less attention as a serological indicator of recent infection, although anti-B19V NS1 IgG has been associated with persistent infection. OBJECTIVES: To elucidate the role of anti-B19V NS1 antibody detection in recent infection, full-length B19V NS1 was expressed and purified. The resultant antigen was used to develop both Western blot assays and microplate ELISA for the detection of NS1 antibodies. STUDY DESIGN: Serum specimens were obtained from individuals recently infected with B19V (children (n=16), adults (n=40)) and from 17 individuals with no evidence of recent B19V infection. All specimens were screened for anti-B19V NS1 IgG and IgM. RESULTS: It was observed that 68.8% (11/16) of children recently infected with B19V were anti-B19V NS1 IgG seropositive. Furthermore, 27.5% (11/40) anti-B19V VP2 IgM positive specimens also contained anti-B19V NS1 IgM when tested by ELISA, while no reactivity was observed following Western blot analysis, possibly due to the absence of conformational epitopes. CONCLUSIONS: Anti-B19V NS1 IgM detection may have utility in the confirmation of recent infection with B19V.

Cloning and overexpression of rat kidney biliverdin IX alpha reductase as a fusion protein with glutathione S-transferase: stereochemistry of NADH oxidation and evidence that the presence of the glutathione S-transferase domain does not effect BVR-A activity.

Native biliverdin IX alpha reductase (BVR-A) is a monomer of molecular mass 34 kDa. We have developed an expression vector that allows the isolation of 40 mg of a glutathione S-transferase (GST)-BVR-A fusion protein from 1 litre of culture. The fusion protein (60 kDa) behaves as a dimer on gel filtration (120 kDa), so that we have artificially created a BVR-A dimer. The recombinant rat kidney enzyme exhibits pre-steady-state 'burst' kinetics that show a pH dependence similar to that already described for ox kidney BVR-A. Similar behaviour was obtained in the presence and absence of the GST domain both for the burst kinetics and during initial-rate studies in the presence and absence of albumin. The stereospecificity of the BVR-A-catalysed oxidation of [4-3H]NADH, labelled at the A and B faces, was shown to occur exclusively via the B face.

Evidence that biliverdin-IX beta reductase and flavin reductase are identical.

A search of the database shows that human biliverdin-IX beta reductase and flavin reductase are identical. We have isolated flavin reductase from bovine erythrocytes and show that the activity co-elutes with biliverdin-IX beta reductase. Preparations of the enzyme that are electrophoretically homogeneous exhibit both flavin reductase and biliverdin-IX beta reductase activities; however, they are not capable of catalysing the reduction of biliverdin-IX alpha. Although there is little obvious sequence identity between biliverdin-IX alpha reductase (BVR-A) and biliverdin-IX beta reductase (BVR-B), they do show weak immunological cross-reactivity. Both enzymes bind to 2',5'-ADP-Sepharose.
