INTRODUCTION: Obesity during pregnancy is associated with meta-inflammation and an increased likelihood of clinical complications. Surgery results in intense, acute inflammatory responses in any individual. Because obese individuals exhibit constitutive inflammatory responses and high rates of Caesarian section, it is important to understand the impact of surgery in such populations. Whether more pronounced pro-inflammatory cytokine responses and/or counterbalancing changes in anti-inflammatory immune modulators occurs is unknown...

OBJECTIVE: To investigate the clinical feasibility and validity of interspinous fastener (ISF) for lumbar degenerative diseases. METHODS: From October 2013 to March 2014, a total of 46 patients suffering from lumbar degenerative diseases underwent posterior lumbar interbody fusion (PLIF) randomly augmented by ISF or pedicle screws. The clinical outcome was primarily measured by Oswestry Disability Index (ODI) score. The minimal clinical important difference (MCID) was defined as an eight-point decrease in ODI...

Species endemic to the tropical regions are expected to be vulnerable to future climate change due in part to their relatively narrow climatic niches. In addition, these species are more likely to have responded strongly to past climatic change, and this can be explored through phylogeographic analyses. To test the hypothesis that tropical specialists are more sensitive to climate change than climate generalists, we generated and analyze sequence data from mtDNA and ~2500 exons to compare scales of historical persistence and population fluctuation in two sister species of Australian rainbow skinks: the tropical specialist Carlia johnstonei and the climate generalist C...

Magnetic Resonance Spectroscopy (MRS) can provide in vivo metabolite concentrations in standard concentration units if a reliable reference signal is available. For (1) H MRS in the human brain, typically the signal from the tissue water is used as the (internal) reference signal. However, a concentration determination based on the tissue water signal most often requires a reliable estimate of the water concentration present in the investigated tissue. Especially in clinically interesting cases, this estimation might be difficult...

BACKGROUND/PURPOSE: Full-field optical coherence tomography (FFOCT) is an emerging imaging technique for rapid histological analysis. As FFOCT is introduced into the Mohs workflow, it is important to document the effect of tissue freezing on FFOCT images and any effect FFOCT has on frozen sections. Our study aimed to evaluate the changes on FFOCT images after tissue freezing as well as FFOCT imaging effects on frozen sectioning. METHODS: Six normal skin specimens were imaged using FFOCT and subsequently frozen using a cryostat...

Vascularized lymph node (VLN) transfer has been of high interest in the past decade for the treatment of lymphedema, since it has been shown to be effective in reducing limb volumes, decreasing infectious episodes and improving quality of life. Multiple donor sites have been described in the quest for the optimal one. Herein, we describe a novel lymph node flap option based on the ileocolic artery and vein. The ileocecal vascularized lymph node (IC-VLN) flap was used in the management of a 33-year-old male patient with lower extremity lymphedema secondary to left inguinal trauma...

KEY POINTS: At the cellular level cardiac hypertrophy causes remodelling, leading to changes in ionic channel, pump and exchanger densities and kinetics. Previous studies have focused on quantifying changes in channels, pumps and exchangers without quantitatively linking these changes with emergent cellular scale functionality. Two biophysical cardiac cell models were created, parameterized and validated and are able to simulate electrophysiology and calcium dynamics in myocytes from control sham operated rats and aortic-banded rats exhibiting diastolic dysfunction...

Escherichia coli RNase E (Eco-RNase E), encoded by rne (Eco-rne), is considered the global RNA decay initiator. Although Eco-RNase E is an essential gene product in E. coli, some bacterial species, such as Bacillus subtilis, do not possess Eco-RNase E sequence homologues. B. subtilis instead possesses RNase J1/J2 (Bsu-RNase J1/J2) and RNase Y (Bsu-RNase Y) to execute RNA decay. Here we found that E. coli lacking the Eco-rne gene (Δrne E. coli) was viable conditional on M9 minimal media by introducing Bsu-RNase J1/J2 or Bsu-RNase Y...

In this paper, we have identified and analyzed the emergence, structure and dynamics of the paradigmatic research fronts that established the fundamentals of the biomedical knowledge on HIV/AIDS. A search of papers with the identifiers "HIV/AIDS", "Human Immunodeficiency Virus", "HIV-1" and "Acquired Immunodeficiency Syndrome" in the Web of Science (Thomson Reuters), was carried out. A citation network of those papers was constructed. Then, a sub-network of the papers with the highest number of inter-citations (with a minimal in-degree of 28) was selected to perform a combination of network clustering and text mining to identify the paradigmatic research fronts and analyze their dynamics...

What is the best way to teach evolution? As microevolution may be configured as a branch of genetics, it being a short conceptual leap from understanding the concepts of mutation and alleles (i.e., genetics) to allele frequency change (i.e., evolution), we hypothesised that learning genetics prior to evolution might improve student understanding of evolution. In the UK, genetics and evolution are typically taught to 14- to 16-y-old secondary school students as separate topics with few links, in no particular order and sometimes with a large time span between...

The under-performance of supply chains presents a significant hindrance to disease control in developing countries. Stock-outs of essential medicines lead to treatment interruption which can force changes in patient drug regimens, drive drug resistance and increase mortality. This study is one of few to quantitatively evaluate the effectiveness of supply chain policies in reducing shortages and costs. This study develops a systems dynamics simulation model of the downstream supply chain for amikacin, a second-line tuberculosis drug using 10 years of South African data...

The reform and development of psychiatric services require, in addition to financial resources, reserves in specialized human resources. The role of psychiatrists in this process, and at reducing the consequences of mental morbidity is evident. Psychiatrists are required to play a multifaceted role as clinicians, as experts in multidisciplinary team environments and as advisors in the recognition of public needs in mental health issues, as teachers and mentors for students and other health professionals, as researchers in order to enrich our knowledge in the scientific field of psychiatry, and as public health specialists in the development of the mental health services system...

Recent research has demonstrated the importance of global changes to the functional organization of brain network following stroke. Resting functional magnetic resonance imaging (R-fMRI) is a non-invasive tool that enables the measurement of functional connectivity (FC) across the entire brain while placing minimal demands on the subject. For these reasons, it is a uniquely appealing tool for studying the distant effects of stroke. However, R-fMRI studies rely on a number of premises that cannot be assumed without careful validation in the context of stroke...

Recurrent focal segmental glomerulosclerosis (FSGS) develops in about 30%-40% of patients of FSGS undergoing renal transplantation. We report a patient who received a live- related renal transplant for end-stage renal disease due to a primary FSGS (not otherwise specified) in the native kidney and presented with graft dysfunction in the immediate posttransplant period. The first and the second biopsy showed no evidence of rejection or glomerular lesion. A repeat biopsy done on the 30th day revealed recurrent FSGS morphologically presenting as collapsing variant...

Epidemiological data of renal diseases have great geographic variability throughout the world. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, clinical and pathological features of various glomerulonephritis (GN) in the United Arab Emirates (UAE). In a retrospective cross-sectional study, we analyzed 158 renal biopsies done in Dubai Hospital, UAE, between the years of 2005 and September 2014, with an aim to determine the prevalence rate and frequency of different pathological patterns of GN in adult patients who presented with proteinuria ± hematuria...

PURPOSE: Hyperthermic intra-thoracic chemotherapy (HITOC) combined with cytoreductive surgery (CRS) is a novel approach in the management of pseuodmyxoma peritonei with thoracic extension. The haemodynamic effects of hyperthermic chemotherapy present an anaesthetic challenge. Here, we describe the haemodynamic changes seen during HITOC. MATERIALS AND METHODS: A retrospective case note review of adult patients undergoing CRS with HITOC from 2009 to 2016. Intra-operative haemodynamics were measured using the LIDCOrapid(TM) brand of invasive cardiac output (CO) monitor...
