The NHS is not one organisation; it’s made up of hundreds of individual organisations, each with their own unique culture - and often sub or ‘micro’ cultures. Consider all of the teams and departments that are working together for patients and their loved ones; where would they be without effective leadership? And for ... |
The largest circular protein structures discovered define a class of transfer proteins acting in bacterial conjugation and type IV secretion. Proteins ranging from 73 to 78 residues with head-to-tail peptide bonds constitute the major subunit of conjugative pili of some type IV secretion systems. Their plasmid-encoded ... |
OBJECTIVE |
Evaluate the existing literature comparing long-term survival after minimally invasive esophagectomy (MIE) and open esophagectomy (OE), and conduct a meta-analysis based on relevant studies. |
BACKGROUND |
It is unknown whether the choice between MIE and OE influences the long-term survival in esophageal cancer. |
METHODS |
A systematic electronic search for articles was performed in Medline, Embase, Web of Science, and Cochrane Library for studies comparing long-term survival after MIE and OE. Additionally, an extensive hand-search was conducted. The I test and χ test were used to test for statistical heterogeneity. Publication bias and ... |
RESULTS |
The review identified 55 relevant studies. Among all 14,592 patients, 7358 (50.4%) underwent MIE and 7234 (49.6%) underwent OE. The statistical heterogeneity was limited [I = 12%, 95% confidence interval (CI) 0%-41%, and χ = 0.26] and the funnel plot was symmetrical both according to visual and statistical testing (Egg... |
CONCLUSIONS |
The long-term survival after MIE compares well with OE and may even be better. Thus, MIE can be recommended as a standard surgical approach for esophageal cancer.Increased regression and decreased incidence of human papillomavirus-related cervical lesions among HIV-infected women on HAART |

In addition, the Editor also suggested that further... |
ABSTRACT— Cognitive disorders are neither a unique nor a constant phenomenon in schizophrenia. Among the dysfunctions that may be observed at times, primarily during acute phases and in patients with a non‐paranoid symptomatology, certain disturbances in attention‐focusing and information processing seem to be most con... |
In this paper, we consider a four‐dimensional version of a human immunodeficiency virus (HIV) infection model, which is an extension of some previous three‐dimensional models. We approach the treatment problem by adding two controls u1 and u2 to the system for inhibiting viral production and preventing new infections. ... |
The parasitic dinoflagellate Hematodinium perezi infects the American blue crab Callinectes sapidus and other decapods along the Eastern seaboard and Gulf of Mexico coast of the USA.

OBJECTIVE |
To determine the prevalence rates of child psychiatric diagnoses in a school-based population of children aged 6 to 8 years in the south of the province of Limburg (The Netherlands). |
METHOD |
In a two-stage design 1,317 children were screened with the Child Behavior Checklist. From 403 of these children, child psychiatric information was obtained with the Amsterdam Diagnostic Interview for Children and Adolescents (ADIKA, DSM-III-R/IV). Data were generalized to the responder group (n = 1,317) and to the ent... |
RESULTS |
Estimates of the prevalence of different ADIKA diagnoses in the responder group were quite comparable with those for the entire cohort. Twenty-four percent of the entire cohort met criteria for a single disorder, and 21.0% met criteria for two or more disorders. However, in only 5.7% of the cases parents did report a n... |
CONCLUSIONS |
Where other studies generalize psychiatric diagnoses to the responder group only, this report adds new information by generalizing the prevalence to a school-based cohort of children aged 6 to 8 years. These prevalence estimates are of importance with regard to the demand for care for child psychopathology.Fractured fa... |

User Datagram Protocol (UDP) is a connectionless transport protocol and part of the TCP/IP protocol suite. UDP provides instruction for applications that involve setting up encapsulated IP data without the need to setup a connection between hosts (e.g., the three-way handshaking TCP). This means that UDP is an unreliab... |
Needs for surgical care are growing in low‐ and middle‐income countries. Existing surgical care capacity indicators, focusing on the availability of equipment, personnel, and operation and anaesthetic skills, are not intended to evaluate perioperative nutrition management, which influences surgical outcomes. In this na... |
