BACKGROUND AND PURPOSE: Implementation of contextually appropriate, evidence-based, expert-recommended stroke prevention guideline is particularly important in Low-Income Countries (LMICs), which bear disproportional larger burden of stroke while possessing fewer resources. However, key quality characteristics of guidelines issued in LMICs compared with those in High-Income Countries (HICs) have not been systematically studied. We aimed to compare important features of stroke prevention guidelines issued in these groups...

BACKGROUND: Disability-adjusted life-years lost after stroke in Low & Middle-Income Countries (LMICs) is almost seven times those lost in High-income countries. Although individuals living with chronic neurological and mental disorders are prone to stigma, there is a striking paucity of literature on stroke-related stigma particularly from LMICs. OBJECTIVE: To assess the prevalence, severity, determinants and psycho-social consequences of stigma among LMIC stroke survivors...

BACKGROUND: Ventriculo-peritoneal shunt surgery is one of the most commonly performed surgery for the management of tuberculous hydrocephalus. There is decreased clarity on issues regarding the indication as well as timing of cerebrospinal fluid diversion procedures in tuberculous meningitis. We systematically analysed published literature on this subject with an objective to assess the value of cerebrospinal fluid diversion procedures in tuberculous meningitis. METHODS: A systematic search of literature was performed using PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) for articles published till August 2016...

REVIEW
Ju Yong Cheong, Anil Keshava
Traumatic colorectal injuries are common during times of military conflict, and major improvements in their care have arisen in such periods. Since World War II, many classification systems for colorectal trauma have been proposed, including (i) Flint Grading System; (ii) Penetrating Abdominal Trauma Index; (iii) Colonic/Rectal Injury Scale; and (iv) destructive/non-destructive colonic injuries. The primary goal of these classifications was to aid surgical management and, more particularly, to determine whether a primary repair or faecal diversion should be performed...

BACKGROUND: The main reason for morbidity after aneurysmal subarachnoid hemorrhage (aSAH) is delayed cerebral ischemia (DCI). The mainstay of medical therapy for treating DCI is induced hypertension with vasopressors to restore cerebral perfusion. Both phenylephrine (PE) and norepinephrine (NE) are commonly used for induced hypertension, but the impact of the initial choice of vasopressor on the efficacy, adverse effects, or outcome after hemodynamic therapy for DCI is unknown. METHODS: Sixty-three patients with aSAH between January 2012 and October 2014, who developed DCI (defined as new focal deficit or decline in Glasgow Coma Score) and in which PE (n = 45) or NE (n = 18) treatment was initiated were evaluated in this retrospective study...

BACKGROUND: Puumala virus (PUUV)-induced hemorrhagic fever with renal syndrome is common in many European countries. The typical renal histologic lesion is acute tubulointerstitial nephritis. We examined the type and kinetics of urine protein excretion and prognostic significance of proteinuria for the severity of acute kidney injury (AKI) in acute PUUV infection. METHODS: The amount of dipstick albuminuria at hospital admission was analyzed in 205 patients with acute PUUV infection...

Glucose transport across glioblastoma membranes plays a crucial role in maintaining the enhanced glycolysis typical of high-grade gliomas and glioblastoma. We tested the ability of two inhibitors of the glucose transporters GLUT/SLC2A superfamily, indinavir (IDV) and ritonavir (RTV), and of one inhibitor of the Na/glucose antiporter type 2 (SGLT2/SLC5A2) superfamily, phlorizin (PHZ), in decreasing glucose consumption and cell proliferation of human and murine glioblastoma cells. We found in vitro that RTV, active on at least three different GLUT/SLC2A transporters, was more effective than IDV, a specific inhibitor of GLUT4/SLC2A4, both in decreasing glucose consumption and lactate production and in inhibiting growth of U87MG and Hu197 human glioblastoma cell lines and primary cultures of human glioblastoma...

Obesity is characterized by chronic low-grade inflammation driven by activation and tissue infiltration of circulating leukocytes. Although exercise has anti-inflammatory effects, the impact of exercise on mediators of leukocyte migration is unclear. PURPOSE: To determine the impact of high intensity interval training (HIIT) versus moderate intensity continuous training (MICT), in the absence of weight/fat loss, on circulating chemokines and leukocyte chemokine receptors. METHODS: Thirty-seven inactive obese adults were randomized to two weeks (10 sessions) of HIIT or MICT with fasting blood samples collected before and after training...

Squamous cell carcinoma (SCC) of the uterine cervix occasionally demonstrates a deceptive growth pattern that mimics endocervical crypt involvement by cervical intraepithelial neoplasia, grade 3 (CIN 3). Such CIN 3-like SCCs may be misinterpreted as noninvasive or minimally invasive leading to delays in diagnosis. Little is known of the factors that influence the growth patterns of cervical SCC but we suggested recently that CIN 3-like tumors might demonstrate "collective cellular invasion," which is characterized by a retained epithelial phenotype...

Although immature teratoma of the ovary is a rare disease, its pathologic grading, especially between low-grade (grade 1) and high-grade (grade 2 or 3) immature teratomas, is important for optimal therapy and prognosis. This grading, however, is currently solely dependent on quantitation of neuroepithelial components as judged by subjective assessments. As we have recently successfully studied the maturation of vascular smooth muscle cells (SMCs) in other organs using an h-caldesmon to α-smooth muscle actin (α-SMA) ratio, we decided to use this ratio to investigate a potential link between teratoma grade and SMC maturation, in combination with Ki-67 index...

Differentiated vulvar intrapeithelial neoplasia (dVIN) is an human papillomavirus (HPV)-independent precursor of squamous cell carcinoma (SCC), and the aim of this study was to better characterize its natural history. Cases of dVIN were identified from the pathology archives. Outcomes of patients with dVIN only, without associated invasive SCC, were compared with a cohort of patients with high-grade squamous intraepithelial lesion [HSIL(VIN3)]. Eighteen patients diagnosed with dVIN with adjacent invasive SCC (SCC/dVIN) and 7 patients with dVIN only, without invasive carcinoma, were identified...

BACKGROUND: The objective of this study was to assess the relationship between exposure to methylprednisolone (MP) and improvements in motor function among patients with acute traumatic spinal cord injury (TSCI). MP therapy for patients with TSCI is controversial because of the current conflicting evidence documenting its benefits and risks. METHODS: We conducted a retrospective cohort study from September 2007 to November 2014 of 311 patients with acute TSCI who were enrolled into a model systems database of a regional, level I trauma center...

The Notch pathway ligand Delta-like 4 (Dll4) functions as an antiangiogenic factor, inhibiting vascular endothelial growth factor (VEGF)-induced angiogenesis. This function is documented in tumor and embryonic vasculature. However, its implication in burn wounds remains unexplored. Our objective was to explore the involvement of the Notch in the healing of zone of stasis burns. We hypothesized that anti-Dll4 therapy would prevent progressive necrosis in the stasis zone by promoting angiogenesis. Burns were created in 21 rats using the comb burn model...

PURPOSE: To assess the accuracy of crowdsourcing for grading optic nerve images for glaucoma using Amazon Mechanical Turk before and after training modules. MATERIALS AND METHODS: Images (n=60) from 2 large population studies were graded for glaucoma status and vertical cup-to-disc ratio (VCDR). In the baseline trial, users on Amazon Mechanical Turk (Turkers) graded fundus photos for glaucoma and VCDR after reviewing annotated example images. In 2 additional trials, Turkers viewed a 26-slide PowerPoint training or a 10-minute video training and passed a quiz before being permitted to grade the same 60 images...

High-grade glioma is a very aggressive and infiltrative tumor in which complete resection is a chance for a better outcome. We present the case of a 57-year-old man with a brain lesion suggestive of high-grade glioma. Brain MRI and F-fluorocholine PET/CT were performed previously to plan the surgery. Surgery was microscope assisted after the administration of 5-aminolevulinic acid. Postsurgery brain MRI and PET were blind evaluated to the surgery results and reported as probably gross total resection.
