PURPOSE: To evaluate the association between ethnic differences and the occurrence of maternal near miss (MNM) in the Amazon and Northeast regions of Brazil. METHODS: This is a secondary analysis of a national cross-sectional study focused on the assessment of care to pregnancy, childbirth, and infants under 1 year of age. Ethnicity was classified as white, black or indigenous. Ethnic distribution by state and region, the proportion of severe maternal complications and related procedures, and the prevalence of MNM and its criteria were calculated for the ethnic groups...

Efficient isolation of target DNA is a crucial first step of DNA-based metagenomic analyses of environmental samples. Insufficient quantity and purity of DNA isolated using commercial kits result in missing genetic information, especially for large-diameter substrates in constructed wetlands (CWs). Here, we addressed this problem by devising a cost-effective calcium chloride lysozyme-sodium dodecyl sulfate (SDS) method (CCLS), with key improvements in the steps of humic acid removal and cell lysis. The buffer comprising Tris, EDTA, Na2O2P7 and PVPP (TENP), and skim milk, could reduce adsorption between microorganisms and substrates, and calcium chloride precipitated and removed over 94% of humic acid...

OBJECTIVES: Unplanned readmissions to the intensive care unit (ICU) are highly undesirable, increasing variance in care, making resource planning difficult and potentially increasing length of stay and mortality in some settings. Identifying patients who are likely to suffer unplanned ICU readmission could reduce the frequency of this adverse event. SETTING: A single academic, tertiary care hospital in the UK. PARTICIPANTS: A set of 3326 ICU episodes collected between October 2014 and August 2016...

INTRODUCTION: We assessed if patients with known hypoglycaemia present on other occasions with non-specific symptoms associated with (but not diagnosed as) hypoglycaemia, potentially representing missed hypoglycaemia. METHODS: 335 primary care records (5/2/12-4/2/13) from patients aged >65 (79 on insulin, 85 on sulphonylureas, 121 on metformin only, 50 without diabetes) were assessed for hypoglycaemia episodes and consultations with non-specific symptoms, "hypo clues"...

BACKGROUND: A minimum future liver remnant (FLR) of 30% is required to avoid post hepatectomy liver failure (PHLF). Portal vein occlusion (PVO) is the main strategy to induce hypertrophy of the FLR, but some patients will not reach sufficient FLR hypertrophy to enable resection. Recently ALPPS has emerged as a "Salvage Procedure" for PVO failure. The aim of this study was to report the short term outcomes of ALPPS following PVO failure. METHODS: A retrospective analysis of patients enrolled within the international ALPPS Registry between October 2012 and November 2015 (NCT01924741) was performed...

PURPOSE: The need for mechanical inpatient bowel preparation (IBP) in reconstructive pediatric urology has come under scrutiny, secondary to literature demonstrating little benefit regarding outcomes. Starting in 2013, a majority of patients undergoing reconstructive procedures at our institution no longer underwent IBP. We hypothesized that outpatient bowel preparation (OBP) would reduce length of stay (LOS) without increasing postoperative complications after appendicovesicostomy surgery...

REVIEW
Christopher Nimsky, Barbara Carl
Intraoperative imaging has become widely accepted in neurosurgery in recent years. The possibility to objectively determine the extent of tumor removal is highly advantageous. If the resection is incomplete, clinicians can attempt to remove the residual tumor that was missed during the same operation. Furthermore, the positioning of implants in spinal surgery, as well as in cranial surgery, can be controlled and modified during the procedure. Intraoperative imaging acts as immediate quality control and offers improved patient safety...

BACKGROUND: The complex association between socioeconomic status (SES) and depressive symptoms is not entirely understood and the existing literature does not address the relationship between early-life SES and later-life depression from a life-course perspective, incorporating mediating events. METHODS: Using data from the Wisconsin Longitudinal Study, we employed structural equation modeling to examine how SES measured at age 18 affects depressive symptoms at age 54 directly and through mediating variables college graduation, marriage, and household income level at age 36...

To determine the diagnostic accuracy of fine needle aspiration (FNA) for detecting malignant parotid tumors. Methods: We conducted a retrospective study of all patients diagnosed with benign or malignant parotid gland tumors in King Abdulaziz University Hospital,  Jeddah, Saudi Arabia, between January 2004 and May 2015. The records of 65 subjects were obtained. Histopathological findings and data from FNA examinations were obtained from medical records. Twenty-three subjects were excluded due to missing FNA, histopathology results or both...

How complex is the memory structure that honeybees use to navigate? Recently, an insect-inspired parsimonious spiking neural network model was proposed that enabled simulated ground-moving agents to follow learned routes. We adapted this model to flying insects and evaluate the route following performance in three different worlds with gradually decreasing object density. In addition, we propose an extension to the model to enable the model to associate sensory input with a behavioral context, such as foraging or homing...

The CLAVATA3/ESR-RELATED (CLE) peptide signals are required for cell-cell communication in several plant growth and developmental processes. However, little is known regarding possible functions of the CLEs in the anther. Here, we show that a T-DNA insertional mutant, and dominant-negative (DN) and overexpression (OX) transgenic plants of the CLE19 gene exhibited significantly reduced anther size and pollen grain number, and abnormal pollen wall formation. Interestingly, the DN-CLE19 pollen grains showed a more extensively covered surface but CLE19-OX pollen exine exhibited clearly missing connections in the network and lacked separation between areas that normally form the lacunae...

Cell mimicry is a nature inspired concept that aims to substitute for missing or lost (sub)cellular function. This review focuses on the latest advancements in the use of enzymes in cell mimicry for encapsulated catalysis and artificial motility in synthetic bottom-up assemblies with emphasis on the biological response in cell culture or more rarely in animal models. Entities across the length scale from nano-sized enzyme mimics, sub-micron sized artificial organelles and self-propelled particles (swimmers) to micron-sized artificial cells are discussed...

The apolipoprotein E4 (ApoE4) gene is the strongest genetic risk factor for Alzheimer's disease (AD). With respect to the other common isoforms of this protein (ApoE2 and ApoE3), ApoE4 is characterized by lower stability that underlies the formation of a stable interaction between the protein's N- and C-terminal domains. AD-related cellular dysfunctions have been linked to this ApoE4 misfolded state. In this regard, it has been reported that the mutation R61T is able to rescue the deleterious cellular effects of ApoE4 by preventing the formation of the misfolded intermediate state...

BACKGROUND: We sought to externally validate our pathologic nodal staging score (pNSS) model, which allows for quantification of the likelihood that a pathologically node-negative patient will not have lymph node (LN) metastasis after radical prostatectomy for prostate cancer (PCa) in a population-based cohort. PATIENTS AND METHODS: We analyzed data from 50,598 patients treated with radical prostatectomy and pelvic LN dissection using the Surveillance, Epidemiology, and End Results database...

BACKGROUND: High physical fitness levels in childhood and adolescence are associated with positive health-related outcomes later in life. Albeit many researchers investigated rural-urban differences in physical fitness, the outcomes of these studies are inconsistent and data on Kosovo are widely missing. Thus, this study aims to examine anthropometric and physical fitness parameters in 14 to 15 year old Kosovan adolescents living in rural and urban areas. METHODS: Two schools from Pristina (mostly urban population) and two schools in the surrounding villages of the district of Deçan (mostly rural population) were selected...

BACKGROUND: To decrease the burden of disease of rheumatoid arthritis (RA), patients at risk for RA need to be identified as early as possible, preferably when no clinically apparent synovitis can be detected. Up to now, it has been fairly difficult to identify those patients with arthralgia who develop inflammatory arthritis (IA), but recent studies using ultrasound (US) suggest that earlier detection is possible. We aimed to identify patients with arthralgia developing IA within 1 year using US to detect subclinical synovitis at first consultation...

INTRODUCTION: Treatment of glioblastoma(GB) patients amenable only for a subtotal resection(STR) is controversial. Since outcome of patients is affected by surgical management, our aim was to assess surgical decision making and resulting outcome in patients with highly eloquent GBs. PATIENTS AND METHODS: We retrospectively assessed GB patients with intended sub-total resection (STR) or stereotactic biopsy (STX) of 3 neurooncological centers operated between 2008 and 2013...

For quality measures, confusion and discontentment have increased, as availability of electronic data and data collection tools has expanded. We examined current issues with quality measures across 4 stakeholder groups: developers, regulators/endorsers, data collectors, and consumer advocates. There are missing quality measures, issues with data quality and purpose, questionable usability of electronic health records, and an increased measurement burden and cost. Policymakers, administrators, health care professionals, and consumers need to collaborate on measure development and selection...

A 59-year-old man developed massive hemoptysis, 1 month after undergoing cryoablation procedure for atrial fibrillation. He underwent emergent bronchoscopy that revealed massive, active bleeding with clots requiring repeated suctioning, epinephrine, and cold saline injection. The source of bleeding was identified in a follow-up bronchoscopy performed few days later-a 2×3 cm area of ulceration of the left main stem bronchus which was missed in the initial bronchoscopy owing to blood obscuring the field of vision...
