Awareness of health risks related to body art practices among youth in Naples, Italy: a descriptive convenience sample study

<p>Abstract</p> <p>Background</p> <p>Body art practices have emerged as common activities among youth, yet few studies have investigated awareness in different age groups of possible health complications associated with piercing and tattooing.</p> <p>Methods</p> <p>We investigated perceptions of and knowledge about health risks. To highlight differences among age groups, we gathered data from students at high schools and universities in the province of Naples.</p> <p>Results</p> <p>Of 9,322 adolescents, 31.3% were pierced and 11.3% were tattooed. Of 3,610 undergraduates, 33% were pierced and 24.5% were tattooed (p < 0.05). A higher number of females were pierced in both samples, but there were no gender differences among tattooed students. Among high school students, 79.4% knew about infectious risks and 46% about non-infectious risks; the respective numbers among university students were 87.2% and 59.1%. Only 3.5% of students in high school and 15% of university undergraduates acknowledged the risk of viral disease transmission; 2% and 3% knew about allergic risks. Among adolescents and young adults, 6.9% and 15.3%, respectively, provided signed informed consent; the former were less knowledgeable about health risks (24.7% vs. 57.1%) (p < 0.05). Seventy-three percent of the high school students and 33.5% of the university students had body art done at unauthorized facilities. Approximately 7% of both samples reported complications from their purchased body art.</p> <p>Conclusions</p> <p>Results indicate a need for adequate information on health risks associated with body art among students in Naples, mainly among high school students. Therefore, adolescents should be targeted for public health education programs.</p

Tattoo removal in the typical adolescent

<p>Abstract</p> <p>Background</p> <p>Although popular tattoos are often regretted later on for different reasons. Nevertheless, tattoo removal is a complicated and costly procedure seldom providing satisfactory results. The aim of this study was to investigate the awareness of the implications of tattoo removal among a substantial sample of Italian secondary school adolescents.</p> <p>Findings</p> <p>Students were recruited by a stratified convenience sample and surveyed by a self administered questionnaire. Logistic regression analysis was performed, reporting adjusted Odds Ratios (OR), with 95% Confidence Interval (CI).</p> <p>4,277 pupils returned a usable questionnaire. Piercings were more frequently undertaken than tattoos. Only 40% of the respondents were aware of the issues related to tattoo removal. Males and pupils with younger fathers were less likely to be aware, whereas students satisfied with their physical appearance and those with a positive attitude towards body art were more likely to be aware.</p> <p>Conclusions</p> <p>Male adolescents with younger fathers can be regarded as the ideal target of corporate health education programs driven by school counsellors and primary care physicians.</p

Exposures of children in Canada to 60-Hz magnetic and electric fields

Objectives This study characterized personal exposures of Canadian children to 60-Hz magnetic and electric fields and explained the variability. Methods Altogether 382 Canadian children up to 15 years of age wore meters recording 60-Hz electric and magnetic fields over 2 days. Meter location was recorded. Thereafter, meters recorded fields in the center of the children's bedrooms for 24 h. Personal exposures were calculated for home, school or day care, outside the home, bedroom at night, and all categories combined (total). Results The arithmetic mean (AM) was 0.121 mT [geometric mean (GM): 0.085 mT), range 0.01-0.8 mT] for total magnetic fields. Fifteen percent of the total exposures exceeded 0.2 mT. The AM of the total electric fields was 14.4 (GM 12.3, range 0.82-64.7) V/m. By location category, the highest and lowest magnetic fields occurred at home during the day (0.142 mT) and during the night (0.112 mT), respectively. Measurements during sleep provided the highest correlation with total magnetic field exposure. Province of measurement explained 14.7% of the variation in the logarithms of total magnetic fields, and season accounted for an additional 1.5%. Electric heating, air conditioning, and housing type appeared to be useful predictors of magnetic field exposures. Conclusions In identifying differences in children's magnetic field exposures between provinces, measurements at night provided the best surrogate for predicting total magnetic field exposure, followed by at-home exposure and 24-h bedroom measurements. Electrical heating and air conditioning, wiring type, and type of housing appear to be promising indicators of magnetic field levels

A randomized control trial of intensive aphasia therapy after acute stroke: The Very Early Rehabilitation for SpEech (VERSE) study.

BACKGROUND:Effectiveness of early intensive aphasia rehabilitation after stroke is unknown. The Very Early Rehabilitation for SpEech trial (VERSE) aimed to determine whether intensive aphasia therapy, beginning within 14 days after stroke, improved communication recovery compared to usual care. METHODS:Prospective, randomized, single-blinded trial conducted at 17 acute-care hospitals across Australia/New Zealand from 2014 to 2018. Participants with aphasia following acute stroke were randomized to receive usual care (direct usual care aphasia therapy), or one of two higher intensity regimens (20 sessions of either non-prescribed (usual care-plus or prescribed (VERSE) direct aphasia therapy). The primary outcome was improvement of communication on the Western Aphasia Battery-Revised Aphasia Quotient (AQ) at 12 weeks after stroke. Our pre-planned intention to treat analysis combined high intensity groups for the primary outcome. FINDINGS:Among 13,654 acute stroke patients screened, 25% (3477) had aphasia, of whom 25% (866) were eligible and 246 randomized to usual care (n = 81; 33%), usual care-plus (n = 82; 33%) or VERSE (n = 83; 34%). At 12 weeks after stroke, the primary outcome was assessed in 217 participants (88%); 14 had died, 9 had withdrawn, and 6 were too unwell for assessment. Communication recovery was 50.3% (95% CI 45.7-54.8) in the high intensity group (n = 147) and 52.1% (95% CI 46.1-58.1) in the usual care group (n = 70; difference -1.8, 95% CI -8.7-5.0). There was no difference between groups in non-fatal or fatal adverse events (p = 0.72). INTERPRETATION:Early, intensive aphasia therapy did not improve communication recovery within 12 weeks post stroke compared to usual care

Analysis of gene expression from the Wolbachia genome of a filarial nematode supports both metabolic and defensive roles within the symbiosis

The α-proteobacterium Wolbachia is probably the most prevalent, vertically transmitted symbiont on Earth. In contrast with its wide distribution in arthropods, Wolbachia is restricted to one family of animal-parasitic nematodes, the Onchocercidae. This includes filarial pathogens such as Onchocerca volvulus, the cause of human onchocerciasis, or river blindness. The symbiosis between filariae and Wolbachia is obligate, although the basis of this dependency is not fully understood. Previous studies suggested that Wolbachia may provision metabolites (e.g., haem, riboflavin, and nucleotides) and/or contribute to immune defense. Importantly, Wolbachia is restricted to somatic tissues in adult male worms, whereas females also harbor bacteria in the germline. We sought to characterize the nature of the symbiosis between Wolbachia and O. ochengi, a bovine parasite representing the closest relative of O. volvulus. First, we sequenced the complete genome of Wolbachia strain wOo, which revealed an inability to synthesize riboflavin de novo. Using RNA-seq, we also generated endobacterial transcriptomes from male soma and female germline. In the soma, transcripts for membrane transport and respiration were up-regulated, while the gonad exhibited enrichment for DNA replication and translation. The most abundant Wolbachia proteins, as determined by geLC-MS, included ligands for mammalian Toll-like receptors. Enzymes involved in nucleotide synthesis were dominant among metabolism-related proteins, whereas the haem biosynthetic pathway was poorly represented. We conclude that Wolbachia may have a mitochondrion-like function in the soma, generating ATP for its host. Moreover, the abundance of immunogenic proteins in wOo suggests a role in diverting the immune system toward an ineffective antibacterial response

Oral nitrate supplementation improves cardiovascular risk markers in COPD: ON-BC a randomised controlled trial

BACKGROUND: Short term studies suggest that dietary nitrate supplementation may improve cardiovascular risk profile, lowering blood pressure (BP) and enhancing endothelial function. It is not clear if these beneficial effects are sustained and whether they apply in people with COPD, who have a worse cardiovascular profile than those without COPD. Nitrate-rich beetroot juice BRJ (NR-BRJ) is a convenient dietary source of nitrate. METHODS: The ON-BC trial was a randomized, double-blind, placebo-controlled parallel group study in stable COPD patients with home systolic BP (SBP) measurement ≥130 mmHg. Participants were randomly allocated (1:1) using computer-generated, block randomization to either 70 mL of NR-BRJ (400 mg NO3 -) (n=40) or an otherwise identical nitrate-depleted placebo juice Pl-BRJ (0 mg NO3 -) (n=41), once daily for 12 weeks. The primary endpoint was between group change in home SBP measurement. Secondary outcomes included change in 6-minute walking distance (6MWD) and measures of endothelial function (reactive hyperaemia index (RHI) and augmentation index (AIx75)) using an EndoPAT device. Plasma nitrate and platelet function were also measured. RESULTS: Compared to placebo, active treatment lowered SBP (Hodges-Lemman treatment effect MD[95% CI]; -4.5[-3.0 to -5.9] improved 6MWD (+30.0 m [15.7 to 44.2], p<0.001), RHI +0.34 (0.03 to 0.63) p=0.03, and AIx75 -7.61% [-14.3 to -0.95], p=0.026. CONCLUSIONS: In people with COPD, prolonged dietary nitrate supplementation in the form of beetroot juice produces a sustained reduction in BP, associated with an improvement in endothelial function and exercise capacity

Body piercing and tattoos: a survey on young adults' knowledge of the risks and practices in body art

<p>Abstract</p> <p>Background</p> <p>The practice of tattooing and piercing has expanded in western society. In order to verify young adults' knowledge of the risk and practices related to body art, an investigation was conducted among freshmen of the University of Bari in the region of Apulia, Italy.</p> <p>Methods</p> <p>The study was carried out in the Academic Year 2009-2010 through an anonymous self-administered written questionnaire distributed to 1.656 freshmen enrolled in 17 Degree Courses.</p> <p>Results</p> <p>Of the 1.598 students included in the analysis, 78.3% believe it is risky to undergo piercing/tattoo practices. AIDS was indicated as a possible infection by 60.3% of freshmen, hepatitis C by 38.2%, tetanus by 34.3% and hepatitis B by 33.7% of the sample. 28.1% of freshmen were not aware that there are also non-infectious complications. 29% of the sample had at least one piercing or tattoo (this percentage does not include earlobe piercing in women). Of those with body art, the decision to undergo body art was made autonomously in 57.9% of the participants. 56.3% of freshmen undergoing body art had taken less than a month to decide. With regard to the reasons that led the sample to undergo body art, 28.4% were unable to explain it, 23.8% answered to improve their aesthetic aspect, 18.4% to distinguish themselves from others, 12.3% for fashion; 17.1% for other reasons. 25.4% of the sample declared that they had a piercing (79.8% female vs 20.2% male; ratio M/F 1:4.0). The average age for a first piercing was 15.3 years (range 10-27; SD ± 2.9). 9.6% of the sample declared that they have a tattoo (69.9% female vs 30.1% male; ratio M/F 1:2.3). The average age for a first tattoo was 17.5 years (range 10-26, SD ± 2.4).</p> <p>Conclusions</p> <p>Most of the freshmen knew about AIDS-related risks but not other potential risks. Body art is fairly common among young adults (especially women). The decision is often not shared with the family and is undertaken mostly without a specific reason or for the improvement of aesthetic aspect. Information about freshmen's knowledge, attitudes and practices could help in effective planning of health promotion strategies.</p

Modelling the nucleon wave function from soft and hard processes

Current light-cone wave functions for the nucleon are unsatisfactory since they are in conflict with the data of the nucleon's Dirac form factor at large momentum transfer. Therefore, we attempt a determination of a new wave function respecting theoretical ideas on its parameterization and satisfying the following constraints: It should provide a soft Feynman contribution to the proton's form factor in agreement with data; it should be consistent with current parameterizations of the valence quark distribution functions and lastly it should provide an acceptable value for the \jp \to N \bar N decay width. The latter process is calculated within the modified perturbative approach to hard exclusive reactions. A simultaneous fit to the three sets of data leads to a wave function whose $x$-dependent part, the distribution amplitude, shows the same type of asymmetry as those distribution amplitudes constrained by QCD sum rules. The asymmetry is however much more moderate as in those amplitudes. Our distribution amplitude resembles the asymptotic one in shape but the position of the maximum is somewhat shifted.Comment: 32 pages RevTex + PS-file with 5 figures in uu-encoded, compressed fil

Prevalence and treatment implications of ICD-11 complex PTSD in Australian treatment-seeking current and ex-serving military members

Background: Despite growing support for the distinction between posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as separate diagnoses within the ICD-11 psychiatric taxonomy, the prevalence and treatment implications of CPTSD among current and ex-serving military members have not been established. Objective: The study aims were to a) establish the prevalence of provisional ICD-11 CPTSD diagnosis relative to PTSD in an Australian sample of treatment-seeking current and ex-serving military members, and b) examine the implications of CPTSD diagnosis for intake profile and treatment response. Methods: The study analysed data collected routinely from Australian-accredited treatment programmes for military-related PTSD. Participants were 480 current and ex-serving military members in this programmes who received a provisional ICD-11 diagnosis of PTSD or CPTSD at intake using proxy measures. Measures of PTSD symptoms, disturbances in self-organisation, psychological distress, mental health and social relationships were considered at treatment intake, discharge, and 3-month follow-up. Results: Among participants with a provisional ICD-11 diagnosis, 78.2% were classified as having CPTSD, while 21.8% were classified as having PTSD. When compared to ICD-11 PTSD, participants with CPTSD reported greater symptom severity and psychological distress at intake, and lower scores on relationship and mental health dimensions of the quality of life measure. These relative differences persisted at each post-treatment assessment. Decreases in PTSD symptoms between intake and discharge were similar across PTSD (dRM = −0.81) and CPTSD (dRM = −0.76) groups, and there were no significant post-treatment differences between groups when controlling for initial scores. Conclusions: CPTSD is common among treatment-seeking current and ex-serving military members, and is associated with initially higher levels of psychiatric severity, which persist over time. Participants with CPTSD were equally responsive to PTSD treatment; however, the tendency for those with CPTSD to remain highly symptomatic post-treatment suggests additional treatment components should be considered
