#1
Kenneth V Iserson
The ethics of providing health care in resource-poor environments is a complex topic. It implies two related questions: What can we do with the resources on hand? Of all the things we can do, which ones should we do? "Resource-poor" (i.e., resource-challenged, resource-constrained) environments are situations in which clinicians, organizations, or healthcare systems have the knowledge and skills, but not the means, to carry out highly effective and beneficial interventions. Determinants of a population's health often rely less on disease and injury management than on recognizing and meeting their basic needs...

Blended learning is the integration of different learning approaches, new technologies and activities that combine traditional face-to-face teaching methods with authentic online methodologies. Although advances in educational technology have helped to expand the selection of different pedagogies, the teaching of anatomical sciences has been challenged by implementation difficulties and other limitations. These challenges are reported to include lack of time, costs, and lack of qualified teachers. Easy access to online information and advances in technology make it possible to resolve these limitations by adopting blended learning approaches...

BACKGROUND: Thousands of individuals with Parkinson's disease (PD) in low-income countries have limited access to marketed levodopa preparations. Mucuna pruriens (MP), a levodopa-containing leguminous plant growing in tropical areas, may be a sustainable alternative therapy for indigent patients. Single-dose intake of MP proved noninferior to marketed levodopa preparations. METHODS: Fourteen PD patients with motor fluctuations and dyskinesias received MP powder (obtained from roasted seeds) and marketed levodopa/carbidopa (LD/CD) in a randomized order and crossover design over a 16-week period...

Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

PURPOSE: The analysis of historical death certificates has enormous potential for understanding how the health of populations was shaped by diseases and epidemics and by the implementation of specific interventions. In Brazil, the systematic archiving of mortality records was initiated only in 1944-hence the analysis of death registers before this time requires searching for these documents in public archives, notaries, parishes, and especially ancient cemeteries, which are often the only remaining source of information about these deaths...

REVIEW

Alemtuzumab is a humanized mAb targeted to CD52. Alemtuzumab is highly immunosuppressive with the ability to deplete T and B cells (in addition to other immune cell lines). A growing understanding of the PKs, dosing, and timing of administration of alemtuzumab has allowed for the study of its use as a conditioning agent for allogeneic HCT. The highly immunosuppressive properties of the drug are particularly appealing in the setting of non-malignant HCT, where GVHD provides no clinical benefit and relapse of malignancy is not applicable...

AIM: To identify pharmacogenetic and demographic variables that influence the systemic exposure to metformin in an admixed Brazilian cohort. METHODS: The extreme discordant phenotype was used to select 106 data sets from nine metformin bioequivalence trials, comprising 256 healthy adults. Eleven single-nucleotide polymorphisms in SLC22A1, SLC22A2, SLC47A1 SLC47A2 and in transcription factor SP1 were genotyped and a validated panel of ancestry informative markers was used to estimate the individual proportions of biogeographical ancestry...

INTRODUCTION: The selection of a surgical approach for buttressing posterolateral tibial plateau fractures is controversial. OBJECTIVE: This study compared the surgical exposure area between the reversed L posteromedial approach (R-PM) and the posterolateral (PL) approach using the lateral plateau width as a metric. MATERIALS AND METHODS: Twenty lower extremities from fresh frozen cadavers were included. The R-PM approach was used first and the boundary of the posterior tibial cortex exposure was marked with metal pins...

Ultrasound has increasingly become a clinical asset in the hands of the anesthesiologist and intensivist who cares for children. Though many applications for ultrasound parallel adult modalities, children as always are not simply small adults and benefit from the application of ultrasound to their management in various ways. Body composition and size are important factors that affect ultrasound performance in the child, as are the pathologies that may uniquely afflict children and aspects of procedures unique to this patient population...

PURPOSE: Image quality of positron emission tomography (PET) tracers that emits high-energy positrons, such as Ga-68, Rb-82, or I-124, is significantly affected by positron range (PR) effects. PR effects are especially important in small animal PET studies, since they can limit spatial resolution and quantitative accuracy of the images. Since generators accessibility has made Ga-68 tracers wide available, the aim of this study is to show how the quantitative results of [68Ga]DOTA-labeled PET/X-ray computed tomography (CT) imaging of neuroendocrine tumors in mice can be improved using positron range correction (PRC)...

Modern biomedical research aims at drawing biological conclusions from large, highly complex biological datasets. It has become common practice to make extensive use of high-throughput technologies that produce big amounts of heterogeneous data. In addition to the ever-improving accuracy, methods are getting faster and cheaper, resulting in a steadily increasing need for scalable data management and easily accessible means of analysis. We present qPortal, a platform providing users with an intuitive way to manage and analyze quantitative biological data...

Histones H1 or linker histones are highly dynamic proteins that diffuse throughout the cell nucleus and associate with chromatin (DNA and associated proteins). This binding interaction of histone H1 with the chromatin is thought to regulate chromatin organization and DNA accessibility to transcription factors and has been proven to involve a kinetic process characterized by a population that associates weakly with chromatin and rapidly dissociates and another population that resides at a binding site for up to several minutes before dissociating...

The Fusarium solani species complex (FSSC) has been studied intensively but its association with legumes, particularly under European agro-climatic conditions, is still poorly understood. In the present study, we investigated phylogenetic relationships and aggressiveness of 79 isolates of the FSSC collected from pea, subterranean clover, white clover and winter vetch grown under diverse agro-climatic and soil conditions within Temperate and Mediterranean Europe. The isolates were characterized by sequencing tef1 and rpb2 loci and by greenhouse aggressiveness assays...

Gene expression is a complex stochastic process composed of numerous enzymatic reactions with rates coupled to hidden cell-state variables. Despite advances in single-cell technologies, the lack of a theory accurately describing the gene expression process has restricted a robust, quantitative understanding of gene expression variability among cells. Here we present the Chemical Fluctuation Theorem (CFT), providing an accurate relationship between the environment-coupled chemical dynamics of gene expression and gene expression variability...
