Ethical rationing of healthcare resources during COVID-19 outbreak: Review.

While rationing of healthcare resources is inevitable even in the most developed economies, particularly on the wake of a pandemic, ethical basis of its implementation needs to be reviewed. With sudden and huge demand for drugs and medical supplies and equipments, the need for rationing arises and thus the concept becomes unavoidable. Thus, we aimed to review and analyse on the key ethical issues in the concept of healthcare rationing. Our search in various PubMed databases resulted articles explaining on the concept of strategizing the priorities based on universal ethical principles of justice, benevolence and ensuring equality rather than wealth, power, geographical location or other personal biases. Concrete and pragmatic regulations and guidelines for systematic rationing have to be framed and followed. In addition, physicians being sensitive and empowered on deciding bedside rationing in coordination with the recommendations of ethicists and healthcare officials, will ensure fair practice.

Cost effectiveness of intraoperative laparoscopic ultrasound for suspected choledocholithiasis; outcomes from a specialist benign upper gastrointestinal unit.

INTRODUCTION: Common bile duct stones are present in 10% of patients with symptomatic gallstones. One-third of UK patients undergoing cholecystectomy will have preoperative ductal imaging, commonly with magnetic resonance cholangiopancreatography. Intraoperative laparoscopic ultrasound is a valid alternative but is not widely used. The primary aim of this study was to assess cost effectiveness of laparoscopic ultrasound compared with magnetic resonance cholangiopancreatography. MATERIALS AND METHODS: A prospective database of all patients undergoing laparoscopic cholecystectomy between 2015 and 2018 at a district general hospital was assessed. Inclusion criteria were all patients, emergency and elective, with symptomatic gallstones and suspicion of common bile duct stones (derangement of liver function tests with or without dilated common bile duct on preoperative ultrasound, or history of pancreatitis). Patients with known common bile duct stones (magnetic resonance cholangiopancreatography or failed endoscopic retrograde cholangiogram) were excluded. Ninety-day morbidity data were also collected. RESULTS: A total of 420 (334 elective and 86 emergency) patients were suspected to have common bile duct stones and were included in the study. The cost of a laparoscopic ultrasound was £183 per use. The cost of using the magnetic resonance cholangiopancreatography unit was £365 per use. Ten postoperative magnetic resonance cholangiopancreatographies were performed for inconclusive intraoperative imaging. The estimated cost saving was £74,650. Some 128 patients had common bile duct stones detected intraoperatively and treated. There was a false positive rate of 4.7%, and the false negative rate at 90 days was 0.7%. laparoscopic ultrasound use saved 129 bed days for emergency patients and 240 magnetic resonance cholangiopancreatography hours of magnetic resonance imaging. CONCLUSION: The use of laparoscopic ultrasound during laparoscopic cholecystectomy for the detection of common bile duct stone is safe, accurate and cost effective. Equipment and maintenance costs are quickly offset and hospital bed days can be saved with its use.

Being ready to treat Ebola virus disease patients.

As the outbreak of Ebola virus disease (EVD) in West Africa continues, clinical preparedness is needed in countries at risk for EVD (e.g., United States) and more fully equipped and supported clinical teams in those countries with epidemic spread of EVD in Africa. Clinical staff must approach the patient with a very deliberate focus on providing effective care while assuring personal safety. To do this, both individual health care providers and health systems must improve EVD care. Although formal guidance toward these goals exists from the World Health Organization, Medecin Sans Frontières, the Centers for Disease Control and Prevention, and other groups, some of the most critical lessons come from personal experience. In this narrative, clinicians deployed by the World Health Organization into a wide range of clinical settings in West Africa distill key, practical considerations for working safely and effectively with patients with EVD.

Comparative assessment of structural and biological properties of biomimetically coated hydroxyapatite on alumina (alpha-Al2O3) and titanium (Ti-6Al-4V) alloy substrates.

Previous reports have shown the use of hydroxyapatite (HAp) and related calcium phosphate coatings on metal and nonmetal substrates for preparing tissue-engineering scaffolds, especially for osteogenic differentiation. These studies have revealed that the structural properties of coated substrates are dependent significantly on the method and conditions used for coating and also whether the substrates had been modified prior to the coating. In this article, we have done a comparative evaluation of the structural features of the HAp coatings, prepared by using simulated body fluid (SBF) at 25 degrees C for various time periods, on a nonporous metal substrate titanium-aluminium-vanadium (Ti-6Al-4V) alloy and a bioinert ceramic substrate alpha-alumina (alpha-Al(2)O(3)), with and without their prior treatment with the globular protein bovine serum albumin (BSA). Our analysis of these substrates by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectrometry showed significant and consistent differences in the quantitative and qualitative properties of the coatings. Interestingly, the bioactivity of these substrates in terms of supporting in vitro cell adhesion and spreading, and in vivo effects of implanted substrates, showed a predictable pattern, thus indicating that some coated substrates prepared under our conditions could be more suitable for biological/biomedical applications.

Cost-effectiveness analysis of laparoscopic versus minilaparotomy cholecystectomy for gallstone disease. A randomized trial.

OBJECTIVE: To evaluate the total cost of minilaparotomy cholecystectomy (MC) and laparoscopic cholecystectomy (LC) and perform a cost-effectiveness (CE) analysis. METHODS: One hundred adult subjects with painful gallstone disease were randomized: 59 cases for LC and 41 cases for MC. Patients with gallstones shown on ultrasound with normal common bile duct and no history of icterus were included after an informed consent. Cases with acute cholecystitis and raised alkaline phosphatase were excluded. LC was performed using CO2 insufflation and a Storz 2D video camera. MC was done by transverse rectus cutting incision. Outcome was coded as success or failure. Success was defined as operation without injury to bile duct, viscera or vessels, minimal pain and discomfort at 4 weeks, no wound infection up to 4 weeks, and resumption of work within 2 weeks of operation. The total cost of each case included cost of investigations, cost of disposable articles for operation, cost of drugs, cost of hospital stay, and cost of operation including anesthesia. LC and MC were done with reusable instruments. A "societal viewpoint" has been taken in the cost calculations. RESULTS: There were 50/59 successful outcomes in LC and 15/40 outcomes in MC group. Total cost for LC was 386,769 rupees (Rs) and for MC was Rs 205,041. CE in LC was Rs 7,735 and in MC was Rs 13,669. Incremental CE ratio comparing LC with MC was 3,028.33. CONCLUSION: LC is a more cost-effective method for treatment of gallstone disease.
