The Management of Periodontally Diseased Individuals-A Registry-Based Study on a Swedish Population.

Objectives: This registry-based study aimed to describe cross-sectional dental and demographic data with focus on diagnosis and treatment of periodontal disease. A second aim was to analyse the extent and content of performed periodontal treatment in patients with varying degrees of periodontitis and if treatment was provided on equal terms. An additional aim was to identify if possible differences in treatments were related to type of dental insurance system.

Methods: We included 130 men with AAA (mean age, 70.

A randomized multi-centre study on the effectiveness of non-surgical periodontal therapy in general practice.

Aim: To evaluate the effectiveness of two non-surgical treatment protocols for periodontitis patients in general dental practice.

Materials And Methods: Ninety-five dental hygienists (59 dental clinics) were randomly assigned to one of two treatment protocols: (i) establishment of adequate self-performed oral hygiene prior to a single session of ultrasonic instrumentation (guided periodontal infection control [GPIC]) or (ii) conventional non-surgical therapy (CNST) including patient education and scaling and root planing integrated in multiple sessions. Residual pockets at 3 months were retreated in both groups.

Patient-reported experiences and outcomes following two different approaches for non-surgical periodontal treatment: a randomized field study.

Context: The current report is part of a prospective, multi-center, two-arm, quasi-randomized field study focusing on the effectiveness in general praxis of evidence-based procedures in the non-surgical treatment of patients with periodontitis.

Objective: The specific aims were to (i) evaluate patient-reported experience and outcome measures of treatment following a guided approach to periodontal infection control (GPIC) compared to conventional non-surgical therapy (CNST) and to (ii) identify potential predictors of subjective treatment outcomes and patient's adherence to self-performed infection control, i.e.

Metformin Prescription Associated with Reduced Abdominal Aortic Aneurysm Growth Rate and Reduced Chemokine Expression in a Swedish Cohort.

Background: Recent reports suggest that the negative association between diabetes mellitus and abdominal aortic aneurysm (AAA) may be driven by metformin, the world's most common antidiabetic drug rather than diabetes per se. We sought to investigate the association among AAA growth rate, chemokine profile, and metformin prescription in a contemporary Swedish cohort.

Methods: Patients under surveillance for small AAA were identified at 4 Swedish vascular centers with active AAA screening programs.

Altered IL-32 Signaling in Abdominal Aortic Aneurysm.

Introduction And Objective: Interleukin (IL)-32 is a pro-inflammatory cytokine not previously studied in relation to abdominal aortic aneurysm (AAA). The aim of this study was to elucidate the expression and localization of IL-32 in AAA.

Methods: Expression and localization of IL-32 in human aortic tissue was studied with immunohistochemical analysis and Western blot (AAA: n = 5; controls: n = 4).

What does carbon tolerant really mean? Operando vibrational studies of carbon accumulation on novel solid oxide fuel cell anodes prepared by infiltration.

Operando Raman spectroscopy and electrochemical techniques were used to examine carbon deposition on niobium doped SrTiO (STN) based SOFC anodes infiltrated with Ni, Co, CeGdO (CGO) and combinations of these materials. Cells were operated with CH/CO mixtures at 750 °C. Raman data shows that carbon forms on all cells under operating conditions when Ni is present as an infiltrate.

Visualizing and quantifying flow stasis in abdominal aortic aneurysms in men using 4D flow MRI.

Purpose: To examine methods for visualizing and quantifying flow stasis in abdominal aortic aneurysms (AAA) using 4D Flow MRI.

Methods: Three methods were investigated: conventional volumetric residence time (VRT), mean velocity analysis (MVA), and particle travel distance analysis (TDA). First, ideal 4D Flow MRI data was generated using numerical simulations and used as a platform to explore the effects of noise and background phase-offset errors, both of which are common 4D Flow MRI artifacts.

Peri-implant tissue healing at implants with different designs and placement protocols: An experimental study in dogs.

Objectives: To compare the peri-implant tissue response to subcrestal or crestal placement of implants with or without "platform-switched" implant/abutment connections.

Material And Methods: On each side of the mandible in six Labrador dogs, two "platform-switched" (PS) implants and two implants with matching implant/abutment diameters (PM) were placed in a crestal or a 1.5 mm subcrestal position.

Age-Related Vascular Changes Affect Turbulence in Aortic Blood Flow.

Turbulent blood flow is implicated in the pathogenesis of several aortic diseases but the extent and degree of turbulent blood flow in the normal aorta is unknown. We aimed to quantify the extent and degree of turbulece in the normal aorta and to assess whether age impacts the degree of turbulence. 22 young normal males (23.

Altered PPARγ Coactivator-1 Alpha Expression in Abdominal Aortic Aneurysm: Possible Effects on Mitochondrial Biogenesis.

Introduction: Abdominal aortic aneurysm (AAA) is a complex and deadly vascular disorder. The pathogenesis of AAA includes destruction and phenotypic alterations of the vascular smooth muscle cells (VSMCs) and aortic tissues. PPARγ coactivator-1 alpha (PGC1α) regulates VSMC migration and matrix formation and is a major inducer of mitochondrial biogenesis and function, including oxidative metabolism.

Inflammatory cells, ceramides, and expression of proteases in perivascular adipose tissue adjacent to human abdominal aortic aneurysms.

Background: Abdominal aortic aneurysm (AAA) is a deadly irreversible weakening and distension of the abdominal aortic wall. The pathogenesis of AAA remains poorly understood. Investigation into the physical and molecular characteristics of perivascular adipose tissue (PVAT) adjacent to AAA has not been done before and is the purpose of this study.

Treatment of Popliteal Aneurysm by Open and Endovascular Surgery: A Contemporary Study of 592 Procedures in Sweden.

Background: Popliteal aneurysm (PA) is traditionally treated by open repair (OR). Endovascular repair (ER) has become more common. The aim was to describe time trends and compare results (OR/ER).

An impact evaluation of a newly developed pediatric cardiac intensive care unit.

Purpose: The highly complex pediatric patients with congenital heart disease require interprofessional teamwork and collaboration to ensure high-quality outcomes with low mortality and morbidity (Congenit Heart Dis. 2013;8:3-19). The purpose of this study was to conduct an impact evaluation for a newly formed pediatric cardiac intensive care unit (PCICU) and to answer: Is there a difference between the pediatric intensive care unit and the PCICU on clinical outcome measures of pediatric cardiac postoperative patients and nursing resources?

Design: A retrospective pretest/posttest design was used with the independent variables being type of intensive care unit.

Placement of two-part implants in sites with different buccal and lingual bone heights.

Background: Recipient sites for implants often exhibit a vertical discrepancy between the buccal and lingual bone crest. The potential to preserve the lingual bone when placing the implant within the dimension determined by the buccal bone in such sites remains to be evaluated.

Methods: Five dogs were included in this study.

Overexpression of the Arabidopsis gai gene in apple significantly reduces plant size.

Genetic engineering is an attractive method to obtain dwarf plants in order to eliminate the extensive use of growth retardants in horticultural crop production. In this study, we evaluated the potential of using the Arabidopsis gai (gibberellic acid insensitive) gene to dwarf apple trees. The gai gene under 35S promoter was introduced in the apple rootstock A2 and the cultivars Gravenstein and McIntosh through Agrobacterium-mediated transformation.

Intron splicing in 5' untranslated region of the rolA transcript in transgenic apple.

The rolA gene encoded on the Ri plasmid of Agrobacterium rhizogenes causes developmental alterations, including dwarfing characteristics in the transgenic plants. In an attempt to introduce dwarfing characteristics into apple rootstocks for breeding purposes, the rolA gene was incorporated into the apple rootstock M26 and obtained four transgenic clones. All the clones exhibited reduced growth compared to untransformed control plants but different degree of dwarfing and wrinkled leaves.
