https://www.readbyqxmd.com/read/28240005/surgery-for-diverticulitis-in-the-21st-century-recent-evidence
#1
Arden M Morris, Cindy Kin
Sigmoid diverticulitis is an increasingly common disease in Western countries. As technology has led to increased knowledge about the disease and options for treatment, management strategies have become less certain. In previous years, the rationale for early elective surgery was largely preventive, due to concern that diverticulitis recurrence would result in increased risk of sepsis or the need for a colostomy. New technology has enabled diagnosis, through computed tomography scans, predictive information through clinical and administrative databases, and less invasive treatment options, through laparoscopic techniques...

RATIONALE: Thrombomodulin (TBM) is an anticoagulant and anti-inflammatory transmembrane protein expressed on endothelial cells. Donor-specific alloantibodies, particularly those against human leukocyte antigen (HLA) class II, are associated with microvascular endothelial damage in solid allografts. OBJECTIVE: Our aim was to characterize the effects of anti-HLA antibodies on endothelial expression of TBM, and in particular, the differential effects of anti-HLA class I compared with those of anti-HLA class II...

A promising replacement for the radioactive sources commonly encountered in ion mobility spectrometers is a miniaturized, energy-efficient photoionization source that produce the reactant ions via soft X-radiation (2.8 keV). In order to successfully apply the photoionization source, it is imperative to know the spectrum of reactant ions and the subsequent ionization reactions leading to the detection of analytes. To that end, an ionization chamber based on the photoionization source that reproduces the ionization processes in the ion mobility spectrometer and facilitates efficient transfer of the product ions into a mass spectrometer was developed...

BACKGROUND: There may be sex-specific cardiometabolic mechanisms early in life that affect the development of type 2 diabetes (T2DM) through mid-adulthood. Yet, there have been few studies examining whether early life-course interactions between cardiometabolic risk factors and sex are associated with incident T2DM. METHODS: We followed n = 7,725 children from the Bogalusa Heart Study through mid-adulthood to examine whether low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), body mass index (BMI), or systolic blood pressure (SBP) differentially impact the risk of T2DM for females versus males...

BACKGROUND: The dogma of administering sufficient intravenous fluids aggressively to avoid under-resuscitation has recently been challenged. Evidence suggests that excessive perioperative fluid administration may be associated with negative clinical outcomes in gastrointestinal surgery. This study examines the impact of fluid administration on perioperative outcomes in patients undergoing pancreatoduodenectomy (PD). METHODS: A retrospective analysis of 202 patients undergoing PD between January 2004 and August 2015 was performed...

Insomnia in prison is common; however, research is limited regarding the management strategies that prison establishments employ. To address this knowledge gap, we conducted a survey to identify how insomnia is detected, diagnosed and treated in adult prisons in England and Wales. Telephone interviews with a purposive sample of health-care managers were then conducted. The survey was sent to all establishments holding adult prisoners, covering screening and assessment methods to detect insomnia; treatment options, both pharmacological and non-pharmacological; the importance of insomnia as a treatable condition; and staff training available...

Adverse symptoms of immunosuppressants (ASI) impact quality of life (QOL) in solid organ transplant recipients, however standardized approaches for active ASI surveillance and intervention are lacking. While management is highly clinician-dependent, clinician views remain largely unexplored. We surveyed Canadian Society of Transplantation members on their perceptions of ASI including frequency, perceived QOL impact, causal attribution, management strategies and success. Sixty-one clinicians participated in the survey of 12 ASI (tremor, diarrhea, nausea, constipation, dyspnea, insomnia, edema, dyspnea, arthralgia, acne, mouth sores, paresthesias), for a 22% response rate...

Latent variable (LV) models are increasingly being used in environmental epidemiology as a way to summarize multiple environmental exposures and thus minimize statistical concerns that arise in multiple regression. LV models may be especially useful when multivariate exposures are collected repeatedly over time. LV models can accommodate a variety of assumptions but, at the same time, present the user with many choices for model specification particularly in the case of exposure data collected repeatedly over time...

α-Synuclein is the primary protein found in Lewy bodies, the protein and lipid aggregates associated with Parkinson's disease and Lewy body dementia. The protein folds into a uniquely long amphipathic α-helix (AH) when bound to a membrane, and at high enough concentrations, it induces large-scale remodeling of membranes (tubulation and vesiculation). By engineering a less hydrophobic variant of α-Synuclein, we previously showed that the energy associated with binding of α-Synuclein's AH correlates with the extent of membrane remodeling (Braun et al...

Inspired by recent experiments on the dynamics of particles and polymers in artificial cytoskeletons and in cells, we introduce a modified Langevin equation for a particle in an environment that is a viscoelastic medium and that is brought out of equilibrium by the action of active fluctuations caused by molecular motors. We show that within such a model, the motion of a free particle crosses over from superdiffusive to subdiffusive as observed for tracer particles in an in vitro cytoskeleton or in a cell. We investigate the dynamics of a particle confined by a harmonic potential as a simple model for the motion of the tethered head of kinesin-1...

Luminescent and temperature sensitive properties of YAG:Cr(3+),Nd(3+) nanocrystals were analyzed as a function of temperature, nanoparticle size, and excitation wavelength. Due to numerous temperature-dependent phenomena (e.g. Boltzmann population, thermal quenching, and inter-ion energy transfer) occurring in this phosphor, four different thermometer definitions were evaluated with the target to achieve a high sensitivity and broad temperature sensitivity range. Using a Cr(3+) to Nd(3+) emission intensity ratio, the highest 3...

The conditioning regimen used as part of the Berlin patient's hematopoietic cell transplant likely contributed to his eradication of HIV infection. We studied the impact of conditioning in simian-human immunodeficiency virus-infected (SHIV-infected) macaques suppressed by combination antiretroviral therapy (cART). The conditioning regimen resulted in a dramatic, but incomplete depletion of CD4(+) and CD8(+) T cells and CD20(+) B cells, increased T cell activation and exhaustion, and a significant loss of SHIV-specific Abs...

Scaffolds for regenerative medicine applications should instruct cells with the appropriate signals, including biophysical stimuli such as stress and strain, to form the desired tissue. Apart from that, scaffolds, especially for load-bearing applications, should be capable of providing mechanical stability. Since both scaffold strength and stress-strain distributions throughout the scaffold depend on the scaffold's internal architecture, it is important to understand how changes in architecture influence these parameters...

Triple-negative breast cancer (TNBC), especially the subset with a basal phenotype, represents the most aggressive subtype of breast cancer. Unlike other solid tumors, TNBCs harbor a low number of driver mutations. Conversely, we and others have demonstrated a significant impact of epigenetic alterations, including DNA methylation and histone post-translational modifications, affecting TNBCs. Due to the promising results in pre-clinical studies, histone deacetylase inhibitors (HDACi) are currently being tested in several clinical trials for breast cancer and other solid tumors...
