Abstract

Objectives Workplace measurements in the past have shown that the applicable occupational exposure limits (OELs) are regularly exceeded in practice when high-emission welding processes are applied. The InterWeld pilot study was planned as part of an intervention study to show under which conditions compliance with the OEL is achievable in gas metal arc welding (GMAW) with solid wire. The investigation focussed on local exhaust ventilation, i.e. captor hoods and welding torches with integrated fume extraction. Methods Forty tests with hand-guided GMAW were configured by experts with regard to all technical parameters and carried out by a professional welder. Effects of protective measures and process parameters on the exposure to respirable welding fumes and airborne manganese (Mn), chromium, nickel, and hexavalent chromium were investigated. Personal sampling was carried out in the welder's breathing zone outside the face shield at high flow rates (10 l min−1) in order to achieve sufficient filter loading. Particle masses and welding fume concentrations were determined by weighing the sampling filters. Metal concentrations were analysed by inductive coupled plasma mass spectrometry. In order to evaluate the effects on exposure, the measurements were performed under similar conditions. The data were analysed descriptively and with mixed linear models. For measurements below the limit of detection, the exposure level was estimated using multiple imputation. Results Two to five times higher exposures to respirable welding fumes and airborne metals were observed during welding of 10 mm sheets than during welding of 2- or 3-mm sheets. Welding fume and Mn exposure were reduced by 70 and 90% when on-torch extraction or a captor hood was applied. Other airborne metals were reduced to a similar extent. Modifications on welding parameters led to a reduction of exposure against respirable particles by 51 up to 54%. Conclusions Although proper extraction at the point of origin and lower-emitting process variants ensure a drastic reduction in exposure, compliance with current OELs is not guaranteed. In order to ensure adequate health protection, especially at workplaces where thick sheets with long relative arc times are processed, there is a need for technical development.

Abstract

PurposeTo determine the prevalence of and identify factors associated with visual impairment and blindness in institutionalized elderly in Germany.MethodsIn this prospective multicenter cross-sectional study, ophthalmic health care need and provision were investigated in institutionalized elderly in 32 nursing homes in Germany. All participants underwent a standardized examination including medical and ocular history, refraction, visual acuity testing, tonometry, biomicroscopy, and dilated funduscopy. A standardized questionnaire was used to identify factors associated with eye healthcare utilization, visual impairment and/or blindness.ResultsVisual acuity of 566 (94.3%; 413 women and 153 men) of a total of 600 institutionalized elderly was determined. Mean age of the included patients was 82.9years (9.8). Of all participants, 30 (5.3%; 95% CI 3.4-7.2%) were blind and 106 (18.7%; 95% CI 15.5-21.9%) were moderately or severely visually impaired according to the World Health Organization definition. The 136 blind and moderately or severely visually impaired participants were older (OR, Odds Ratio=1.1, 95% CI 1.0-1.1; p<0.001), and more likely to have reduced mobility (OR=12.6, 95% CI 2.8-57.6; p=0.001).Conclusion p id=Par4 A high proportion of blindness and visual impairment was found amongst nursing home residents. Age and reduced mobility were factors associated with an increased likelihood of blindness and visual impairment. Any surveys of blindness and visual impairment excluding nursing homes may considerably underestimate the prevalence of visual impairment and blindness.

Abstract

Building on previous work, we present a proposal for a pragmatic account of biscuit conditionals (BCs). We present a new phenomenon that we dub biscuit perfection to support our proposal and argue that differences between BCs and hypothetical conditionals can be explained once we consider the relation between if -constructions and discourse. published

Abstract

Importance Anti–vascular endothelial growth factor (VEGF) therapies are a novel treatment option in retinopathy of prematurity (ROP). Data on dosing, efficacy, and safety are insufficient. Objective To investigate lower doses of anti-VEGF therapy with ranibizumab, a substance with a significantly shorter systemic half-life than the standard treatment, bevacizumab. Design, Setting, and Participants This randomized, multicenter, double-blind, investigator-initiated trial at 9 academic medical centers in Germany compared ranibizumab doses of 0.12 mg vs 0.20 mg in infants with bilateral aggressive posterior ROP; ROP stage 1 with plus disease, 2 with plus disease, or 3 with or without plus disease in zone I; or ROP stage 3 with plus disease in posterior zone II. Patients were recruited between September 2014 and August 2016. Twenty infants were screened and 19 were randomized. Interventions All infants received 1 baseline ranibizumab injection per eye. Reinjections were allowed in case of ROP recurrence after at least 28 days. Main Outcomes and Measures The primary end point was the number of infants who did not require rescue therapy at 24 weeks. Key secondary end points included time-to-event analyses, progression of physiologic vascularization, and plasma VEGF levels. Stages of ROP were photodocumented and reviewed by an expert committee. Results Nineteen infants with ROP were enrolled (9 [47.4%] female; median [range] postmenstrual age at first treatment, 36.4 [34.7-39.7] weeks), 3 of whom died during the study (1 in the 0.12-mg group and 2 in the 0.20-mg group). Of the surviving infants, 8 (88.9%) (17 eyes [94.4%]) in the 0.12-mg group and 6 (85.7%) (13 eyes [92.9%]) in the 0.20-mg group did not require rescue therapy. Both ranibizumab doses were equally successful in controlling acute ROP (Cochran-Mantel-Haenszel analysis; odds ratio, 1.88; 95% CI, 0.26-13.49;P = .53). Physiologic intraretinal vascularization was superior in the 0.12-mg group. The VEGF plasma levels were not systematically altered in either group. Conclusions and Relevance This pilot study demonstrates that ranibizumab is effective in controlling acute ROP and that 24% of the standard adult dose (0.12 mg) appears equally effective as 40% (0.20 mg). Superior vascularization of the peripheral retina with 0.12 mg of ranibizumab indicates that the lower dose may be favorable. Unchanged plasma VEGF levels point toward a limited systemic drug exposure after ranibizumab.
