Impact of sense of coherence on oral health-related quality of life among brazilian adults
It has been postulated that oral health-related quality of life (OHRQoL) may be affected by the sense of coherence (SOC), but there are no epidemiological studies investigating this association in Brazilian adults. The present study was conducted among adults of a mid-sized Brazilian city, with the aim of looking into this association. The probability sampling consisted of 342 adults aged 35-44 years old, from a mid-sized Brazilian city, who were examined at their homes for caries (Decayed, Missing and Filled Teeth [DMFT] Index) and periodontal disease (Community Periodontal Index - CPI), according to WHO criteria. The questionnaire applied included demographic factors, socioeconomic information, use of dental services, behavior, SOC and the Oral Health Impact Profile (OHIP). The OHIP outcome, measured by prevalence of the impact, was analyzed by binary logistic regression using a hierarchical approach, a conceptual model, and a 5% significance level. A total of 67.9% of the respondents had one or more impacts on OHRQoL, and 54.4% showed a high SOC. The impact on OHRQoL was more prevalent in adults who had a manual occupation (PR = 2.47, 95%CI 1.24-4.93), those who perceived the need for dental treatment (PR = 2.93, 95%CI 1.67-5.14), and those who had untreated caries (PR = 1.93, 95%CI 1.07-3.47). Those with a low SOC had a twofold higher prevalence of impact on OHRQoL (PR = 2.19, 95%CI 1.29-3.71). This impact on OHRQoL was associated with a low SOC, even after adjusted by socioeconomic, behavioral and clinical factors. Future studies should consider the SOC in determining the oral health impact on quality of life3
A follow-up study of a large group of children struck by lightning
BACKGROUND. On 11 November 1994, 26 preadolescent girls, 2 adult supervisors and 7 dogs were sleeping in a tent in rural South Africa
when the tent was struck by lightning. Four of the girls and 4 of the dogs were killed. The 2 adults were unharmed, but all but 3 of the
children suffered significant injuries. An article in 2002 detailed the event and examined the medical and psychological changes in the
surviving girls.
OBJECTIVE. To understand the medical and psychological changes secondary to lightning strike years after injury.
METHODS. An online questionnaire was prepared that included a checklist of physical and psychological symptoms. Participants were asked
to report on both initial and current symptoms. Eleven of the 22 survivors were contacted, and 10 completed the survey.
RESULTS. Participants reported that initial physical symptoms generally resolved over time, with ~10 - 20% continuing to experience physical
symptoms. Vision problems persisted in 50% of respondents. Psychological symptoms, overall, had a later onset and were more likely to
be chronic or currently experienced. Depression and anxiety, specifically, were higher among the survivors than the reported incidence in
South Africa.
CONCLUSIONS. Initial and current/chronic physical and psychological symptoms following lightning strike are reported, adding to the
body of literature on the long-term after-effects of lightning strike on survivors. A brief discussion on post-traumatic stress disorder
symptomatology and post-lightning shock syndrome is provided.The original work and meticulous documentation of the lightning incident
by Carte et al.[1] needs to be acknowledged. We would also like to thank
Dr Christopher Andrews for sharing his symptoms questionnaire from
his 1989 long-term telephone lightning injury survey. The authors would
also like to acknowledge and thank the respondents for making themselves
available for this study. We are acutely aware of the courage it must have
taken to re-confront this tragic incident 19 years later.http://www.samj.org.zaam2016Forensic Medicin
Bayesian Forecasting Of Temporal Gene Expression By Using An Autoregressive Panel Data Approach
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)We propose and evaluate a novel approach for forecasting gene expression over non-observed times in longitudinal trials under a Bayesian viewpoint. One of the aims is to cluster genes that share similar expression patterns over time and then use this similarity to predict relative expression at time points of interest. Expression values of 106 genes expressed during the cell cycle of Saccharomyces cerevisiae were used and genes were partitioned into five distinct clusters of sizes 33, 32, 21, 16, and 4. After removing the last observed time point, the agreements of signals (upregulated or downregulated) considering the predicted expression level were 72.7, 81.3, 76.2, 68.8, and 50.0%, respectively, for each cluster. The percentage of credibility intervals that contained the true values of gene expression for a future time was ~90%. The methodology performed well, providing a valid forecast of gene expression values by fitting an autoregressive panel data model. This approach is easily implemented with other time-series models and when Poisson and negative binomial probability distributions are assumed for the gene expression data. © FUNPEC-RP.152CAPES, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCNPq, Conselho Nacional de Desenvolvimento Científico e Tecnológico#APQ 00825, FAPEMIG, Fundação de Amparo à Pesquisa do Estado de Minas GeraisFUNARBE, Fundação Arthur BernardesCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
