Standardized approach to polypectomy of diminutive colorectal polyps (DCPs) is lacking since cold biopsy forceps have been associated with high levels of recurrence, hot biopsy forceps are considered inadequate and risky and cold snaring is currently under investigation for its efficacy and safety. This has led to confusion and a gap in clinical practice. This article discusses the usefulness and contemporary practical applicability of hot biopsy forceps and provides well-intentioned criticism of the new European guidelines for the treatment of DCPs...

Background: Submicroscopic malaria infections contribute to malaria transmission. Describing the extent of the parasite reservoir is of importance. In people living with human immunodeficiency virus (HIV), the frequency of subpatent malaria infections is rarely reported. The aim of the present study was to determine the frequency of submicroscopic infections in people living with HIV in Gabon and its relationship with cotrimoxazole (CTX) use. Methods: A survey was conducted in two health care centres in rural areas (Koulamoutou and Oyem) and three in urban areas (Libreville) of Gabon from March 2015 to June 2016...

Herein, we report the development of a simple, high-throughput and efficient microfluidic system for synthesizing radioactive [18F]fallypride, a PET imaging radiotracer widely used in medical research. The microfluidic chip contains all essential modules required for the synthesis and purification of radioactive fallypride. The radiochemical yield of the tracer is sufficient for multiple animal injections for preclinical imaging studies. To produce the on-chip concentration and purification columns, we employ a simple "trapping" mechanism by inserting rows of square pillars with predefined gaps near the outlet of microchannel...

Biodegradable injectable hydrogels have been extensively studied and evaluated in various medical applications such as for bulking agents, drug delivery reservoirs, temporary barriers, adhesives, and cell delivery matrices. Where injectable hydrogels are intended to facilitate a healing response, it may be desirable to encourage rapid cellular infiltration into the hydrogel volume from the tissue surrounding the injection site. In this study, we developed a platform technique to rapidly form pores in a thermally responsive injectable hydrogel, poly(NIPAAm-co-VP-co-MAPLA) by using mannitol particles as porogens...

Necrotizing fasciitis (NF) is a life-threatening infection of soft tissues spreading along the fasciae to the surrounding musculature, subcutaneous fat and overlying skin areas that can rapidly lead to septic shock and death. Due to the pandemic increase of medical malpractice lawsuits, above all in Western countries, the forensic pathologist is frequently asked to investigate post-mortem cases of NF in order to determine the cause of death and to identify any related negligence and/or medical error. Herein, we review the medical literature dealing with cases of NF in a post-mortem setting, present a case series of seven NF fatalities and discuss the main ante-mortem and post-mortem diagnostic challenges of both clinical and forensic interests...

This article presents four hypothetical cases that demonstrate ways in which neurologists may be vulnerable to liability for how they manage patients they refer to other physicians for consultations. This article also discusses the importance of protecting neurologists from claims of negligence through documentation, which includes the rationale for ordering a consultation, deferring a consultation, or disagreeing with a consultant's recommendations. Lastly, the article discusses the importance of including patients in the decision-making process and detailing these conversations in the medical record...

INTRODUCTION: Autonomy is a fundamental patient right for ethical practice, and informed consent is the mechanism by which health care professionals ensure this right has been respected. The ethical notion of informed consent has evolved alongside legal developments. Under Australian law, a provider who fails to disclose risk may be found to be in breach of a duty of disclosure, potentially facing legal consequences if the patient experiences harm that is attributable to an undisclosed risk...

Vertebral fractures associated with the loss of structural integrity of neoplastic vertebrae are common, and determined to the deterioration of the bone quality in the lesion area. The prediction of the fracture risk in metastatically involved spines can guide in deciding if preventive solutions, such as medical prophylaxis, bracing, or surgery are indicated for the patient. In this study, finite element models of 22 thoracolumbar vertebrae were built based on CT scans of three spines, covering a wide spectrum of possible clinical scenarios in terms of age, bone quality and degenerative features, taking into account the local material properties of bone tissue...

Context/objective Acute care readmission has been identified as an important marker of healthcare quality. Most previous models assessing risk prediction of readmission incorporate variables for medical comorbidity. We hypothesized that functional status is a more robust predictor of readmission in the spinal cord injury population than medical comorbidities. Design Retrospective cross-sectional analysis.

Fucose-containing sulfated glycans (syn. fucoidans) from brown algae exhibit a wide range of bioactivities and are therefore considered promising candidates for health-supporting and medical applications. In this study, we investigated the pharmacological activities of fucoidan from Fucus vesiculosus and 18 gradually depolymerized fractions, which were obtained by hydrothermal and H2 O2 treatment, respectively. All the activities decreased with decreasing molecular mass (Mw ) but to a different extent resulting in some modified pharmacological profiles in dependence on the Mw as well as on the degradation method...

Malcolm K Smith, Tracey Carver
The UK Supreme Court in Montgomery v Lanarkshire Health Board adopts an approach to information disclosure in connection with clinical treatment that moves away from medical paternalism towards a more patient-centred approach. In doing so, it reinforces the protection afforded to informed consent and autonomous patient decision making under the law of negligence. However, some commentators have expressed a concern that the widening of the healthcare providers' duty of disclosure may provide impetus, in future cases, for courts to adopt a more rigorous approach to the application of causation principles...

For the first 180 years following the founding of the US, physicians occasionally were sued for medical malpractice. Allegations of negligence were errors of commission - i.e. the physician made a mistake by doing something wrong, usually mistreatment of a fracture or dislocation, a complication or death following a surgical procedure, prescribing the wrong medication, and after the discovery of the X-ray by Roentgen in 1895, causing radiation burns. In the mid twentieth century malpractice allegations slowly changed from errors of commission to errors of omission - i...

Medical emergencies are one of the most stressful situations the staff in a dental practice might encounter. The duty of care toward the attending patients obligates suitable preparedness to provide the necessary care if such emergencies ensue. Unfortunately, we found that 22% of the investigated dental clinics had no emergency kit available. Only 38% of the interviewed dentists felt confident to perform CPR, and 18% had no confidence to manage any medical emergency. An MCQ test of 20 questions examining the dentists' knowledge in medical emergencies was distributed, and the level of knowledge was found to be suboptimal...

Human heart electrophysiology is complex biological phenomenon, which is indirectly assessed by the measured ECG signal. ECG trace is further analyzed to derive interpretable surrogates including QT interval, QRS complex, PR interval, and T wave morphology. QT interval and its modification are the most commonly used surrogates of the drug triggered arrhythmia, but it is known that the QT interval itself is determined by other nondrug related parameters, physiological and pathological. In the current study, we used the computational intelligence algorithms to analyze correlations between various simulated physiological parameters and QT interval...
