Dental implant and bone augmentation treatment in bone-compromised patients: Oral health-related quality of life outcomes.

STATEMENT OF PROBLEM: Patient-reported outcomes represent an additional and often overlooked measure of dental implant and bone augmentation treatment. Few implant studies have evaluated patient-reported outcomes in those with systemic bone compromise. PURPOSE: The purpose of this cohort study was to assess oral health-related quality of life (OHRQoL) outcomes in postmenopausal women receiving dental implants with normal bone density or mild osteopenia ("healthy" group; all DXA T-scores at femoral neck, total hip, and L1-L4 spine>-2.0) versus moderate osteopenia or osteoporosis ("bone compromised" group; any DXA T-score at femoral neck, total hip, or L1-L4 spine≤-2.0). MATERIAL AND METHODS: A total of 115 patients were recruited at the University of Connecticut School of Dental Medicine as part of a standard of care, prospective, nonrandomized cohort study. All participants received 1 of 3 bone augmentation procedures with implant placement. At baseline and at various intervals after implant placement, OHRQoL was measured by using the Oral Health Impact Profile-14 (OHIP-14) and surveys of patient expectations and satisfaction. These measures were compared between healthy and bone compromised groups (α=.05). RESULTS: For all OHRQoL measures across linear mixed effects models, no significant differences were found between bone groups at baseline and at each time point after implant placement (P>.05). Using the minimally important difference (MID) for OHIP-14, no definitive clinical differences were found in patient outcomes between bone groups at all postimplant time points (P>.05). From baseline to 24 months after implant placement, both healthy and bone compromised groups exhibited significant improvements in OHIP-14 and patient expectations scores (P<.05). While no within group differences were found in patient satisfaction scores, the mean satisfaction score remained high over time in both groups. CONCLUSIONS: Patient-reported outcomes as measured through OHIP-14, patient expectations, and patient satisfaction surveys suggest similar postimplant OHRQoL improvement in healthy and bone compromised individuals. OHRQoL improvements between bone groups were similar both in continuity and in scope, with no evidence of statistically significant score differences between groups at 24 months after implant placement across all measures and with no definitive evidence of clinical differences as measured by OHIP-14 MID comparisons across all timepoints.

COVID-19 global pandemic planning: Performance and electret charge of N95 respirators after recommended decontamination methods.

Shortages of N95 respirators for use by medical personnel have driven consideration of novel conservation strategies, including decontamination for reuse and extended use. Decontamination methods listed as promising by the Centers for Disease Control and Prevention (CDC) (vaporous hydrogen peroxide (VHP), wet heat, ultraviolet irradiation (UVI)) and several methods considered for low resource environments (bleach, isopropyl alcohol and detergent/soap) were studied for two commonly used surgical N95 respirators (3M™ 1860 and 1870+ Aura™). Although N95 filtration performance depends on the electrostatically charged electret filtration layer, the impact of decontamination on this layer is largely unexplored. As such, respirator performance following decontamination was assessed based on the fit, filtration efficiency, and pressure drop, along with the relationship between (1) surface charge of the electret layer, and (2) elastic properties of the straps. Decontamination with VHP, wet heat, UVI, and bleach did not degrade fit and filtration performance or electret charge. Isopropyl alcohol and soap significantly degraded fit, filtration performance, and electret charge. Pressure drop across the respirators was unchanged. Modest degradation of N95 strap elasticity was observed in mechanical fatigue testing, a model for repeated donnings and doffings. CDC recommended decontamination methods including VHP, wet heat, and UV light did not degrade N95 respirator fit or filtration performance in these tests. Extended use of N95 respirators may degrade strap elasticity, but a loss of face seal integrity should be apparent during user seal checks. NIOSH recommends performing user seal checks after every donning to detect loss of appropriate fit. Decontamination methods which degrade electret charge such as alcohols or detergents should not be used on N95 respirators. The loss of N95 performance due to electret degradation would not be apparent to a respirator user or evident during a negative pressure user seal check.

The gluten-free diet and its current application in coeliac disease and dermatitis herpetiformis.

BACKGROUND: A gluten-free diet (GFD) is currently the only available therapy for coeliac disease (CD). OBJECTIVES: We aim to review the literature on the GFD, the gluten content in naturally gluten-free (GF) and commercially available GF food, standards and legislation concerning the gluten content of foods, and the vitamins and mineral content of a GFD. METHODS: We carried out a PubMed search for the following terms: Gluten, GFD and food, education, vitamins, minerals, calcium, Codex wheat starch and oats. Relevant papers were reviewed and for each topic a consensus among the authors was obtained. CONCLUSION: Patients with CD should avoid gluten and maintain a balanced diet to ensure an adequate intake of nutrients, vitamins, fibre and calcium. A GFD improves symptoms in most patients with CD. The practicalities of this however, are difficult, as (i) many processed foods are contaminated with gluten, (ii) staple GF foods are not widely available, and (iii) the GF substitutes are often expensive. Furthermore, (iv) the restrictions of the diet may adversely affect social interactions and quality of life. The inclusion of oats and wheat starch in the diet remains controversial.

Diagnosis and management of adult coeliac disease: guidelines from the British Society of Gastroenterology.

A multidisciplinary panel of 18 physicians and 3 non-physicians from eight countries (Sweden, UK, Argentina, Australia, Italy, Finland, Norway and the USA) reviewed the literature on diagnosis and management of adult coeliac disease (CD). This paper presents the recommendations of the British Society of Gastroenterology. Areas of controversies were explored through phone meetings and web surveys. Nine working groups examined the following areas of CD diagnosis and management: classification of CD; genetics and immunology; diagnostics; serology and endoscopy; follow-up; gluten-free diet; refractory CD and malignancies; quality of life; novel treatments; patient support; and screening for CD.

The Oslo definitions for coeliac disease and related terms.

OBJECTIVE: The literature suggests a lack of consensus on the use of terms related to coeliac disease (CD) and gluten. DESIGN: A multidisciplinary task force of 16 physicians from seven countries used the electronic database PubMed to review the literature for CD-related terms up to January 2011. Teams of physicians then suggested a definition for each term, followed by feedback of these definitions through a web survey on definitions, discussions during a meeting in Oslo and phone conferences. In addition to 'CD', the following descriptors of CD were evaluated (in alphabetical order): asymptomatic, atypical, classical, latent, non-classical, overt, paediatric classical, potential, refractory, silent, subclinical, symptomatic, typical, CD serology, CD autoimmunity, genetically at risk of CD, dermatitis herpetiformis, gluten, gluten ataxia, gluten intolerance, gluten sensitivity and gliadin-specific antibodies. RESULTS: CD was defined as 'a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed individuals'. Classical CD was defined as 'CD presenting with signs and symptoms of malabsorption. Diarrhoea, steatorrhoea, weight loss or growth failure is required.' 'Gluten-related disorders' is the suggested umbrella term for all diseases triggered by gluten and the term gluten intolerance should not to be used. Other definitions are presented in the paper. CONCLUSION: This paper presents the Oslo definitions for CD-related terms.

Synthesis of an ionic liquid with an iron coordination cation.

An iron-based ionic liquid, Fe((OHCH(2)CH(2))(2)NH)(6)(CF(3)SO(3))(3), is synthesized in a single-step complexation reaction. Infrared and Raman data suggest NH(CH(2)CH(2)OH)(2) primarily coordinates to Fe(iii) through alcohol groups. The compound has T(g) and T(d) values of -64 degrees C and 260 degrees C, respectively. Cyclic voltammetry reveals quasi-reversible Fe(iii)/Fe(ii) reduction waves.

Welfare reform, time limits, and infant health.

This paper offers evidence that welfare time limits contributed to a deterioration of infant health. We use the fact that the dates at which TANF recipients were first subject to timing out varied by state. We show that by 2000 there was a marked difference in TANF duration spells depending on whether the state employed the 60-month Federally imposed time limit, or a shorter limit, differences that were not present under AFDC. There were significant increases in infant mortality when time limits became binding in a state. These increases occurred primarily among mothers who could have plausibly timed-out of TANF: poorly educated and unmarried women with at least one previous live-birth. There is some evidence that the population of mothers affected by time limits were less likely to seek prenatal care in the first trimester, suggesting a possible role for reduced medical care in explaining the deterioration in infant health.
