This study assessed differences in response rates to a series of three-wave mail surveys when amiable or insistently worded postcards were the third wave of the mailing. Three studies were conducted; one with a sample of 600 health commissioners, one with a sample of 680 vascular nurses, and one with 600 elementary school secretaries. The combined response rates for the first and second wave mailings were 65.8%, 67.6%, and 62.4%, respectively. A total of 308 amiable and 308 insistent postcards were sent randomly to nonrespondents as the third wave mailing. Overall, there were 41 amiable and 52 insistent postcards returned, not significantly different by chi-square test. However, a separate chi-square test for one of the three studies, the nurses' study, did find a significant difference in favor of the insistently worded postcards.

ABSTRACTObjectivesTo describe time trends in social contacts of individuals according to comorbidity and vaccination status before and during the first three waves of the COVID-19 pandemic in Quebec, Canada.DesignRepeated cross-sectional population-based surveys.SettingGeneral population.ParticipantsNon-institutionalized adults from Quebec, Canada, recruited by random digit dialling before (2018/2019) and during the pandemic (April 2020 to July 2021). A total of 1441 and 5185 participants with and without comorbidities, respectively, were included in the analyses.Main outcome measuresNumber of social contacts (two-way conversation at a distance ≤2 meters or a physical contact, irrespective of masking) documented in a self-administered web-based questionnaire. We compared the mean number of contacts according to the comorbidity status of participants (pre-existing medical conditions with symptoms/medication in the past 12 months) and 1-dose vaccination status during the third wave. All analyses were performed using weighted generalized linear models with a Poisson distribution and robust variance.ResultsContacts significantly decreased from a mean of 6.1 (95% confidence interval 4.9 to 7.3) before the pandemic to 3.2 (2.5 to 3.9) during the first wave among individuals with comorbidities, and from 8.1 (7.3 to 9.0) to 2.7 (2.2 to 3.2) among individuals without comorbidities. Individuals with comorbidities maintained fewer contacts than those without comorbidities in the second wave, with a significant difference before the Christmas 2020/2021 holidays (2.9 (2.5 to 3.2) v 3.9 (3.5 to 4.3); P<0.001). During the third wave, contacts were similar for individuals with (4.1, 3.4 to 4.7) and without comorbidities (4.5, 4.1 to 4.9; P=0.27). This could be partly explained by individuals with comorbidities vaccinated with their first dose who increased their contacts to the level of those without comorbidities.ConclusionsThe lower level of contacts maintained by individuals with comorbidities could have influenced the burden of hospitalisations and deaths of the second wave in Quebec. It will be important to closely monitor COVID-19-related outcomes and social contacts by comorbidity and vaccination status to inform targeted or population-based interventions.

The Impact

A 2 × 2 factorial experiment was designed to test the impact on mail survey response rate resulting from variations in paper trim size and number of printed pages in the questionnaire. ANOVA findings suggest 8½ × 11″ paper trim size produces a better response rate than an 8½ × 14″ paper trim size. Use of a one-sheet (front and back) versus a two-sheet (front only) questionnaire did not cause a significant difference in response rate; a hypothesized interaction effect was not found to be statistically significant.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Abstract Background To analyze whether corneal refractive surgery (CRS) is associated with the distribution of different accommodative dysfunctions (ADs) and binocular dysfunctions (BDs) in civilian pilots. A further aim was to analyze the percentages and visual symptoms associated with ADs and/or BDs in this population. Methods One hundred and eight civilian pilots who underwent CRS from January 2001 to July 2012 (age: 30.33 ± 4.60 years) were enrolled, the mean preoperative SE was − 1.51 ± 1.15 D (range: − 1.00- − 5.00 D). Ninety-nine emmetropic civilian pilots (age: 29.64 ± 3.77 years) who were age- and sex-matched to the CRS group were also enrolled. Refractive status, accommodative and binocular tests of each subject were performed. Visually related symptoms were quantified using the 19-item College of Optometrists in Vision Development Quality of Life (COVD-QOL) questionnaire. The 19 items were summed to obtain visual symptom scores that might indicate visual dysfunctions. The chi-square test was used to analyze differences in percentages of ADs and/or BDs between the CRS and emmetropic groups. The Mann-Whitney U test was used to compare visual symptom scores between pilots with ADs and/or BDs and pilots with normal binocular vision. Results No significant difference was observed between the CRS and emmetropic groups in the overall prevalence of ADs and BDs (15.7% and 15.2% in the CRS and emmetropic groups, respectively; P = 0.185). ADs were present in 4.63% and 3.03% of the CRS and emmetropic group, respectively. BDs were observed in 11.1% and 12.1% of the CRS and emmetropic group, respectively, yielding no significant differences between the groups in the prevalence of ADs or BDs (AD: P = 0.094; BD: P = 0.105). Pilots with ADs and/or BDs had significantly more visual symptoms than pilots with normal binocular vision (p < 0.001). Conclusions CRS for civilian pilots with low-moderate myopia might not impact binocular functions. ADs and/or BDs commonly occur in both emmetropia pilots and pilots who undergo CRS, and pilots with ADs and/or BDs are associated with increased symptoms. This study confirms the importance of a full assessment of binocular visual functions in detecting and remedying these dysfunctions in this specific population.

Propolis is proposed to possess antibacterial and anti-inflammatory properties, which can be used in endodontic applications. However, evidence on its efficacy in comparison to chlorhexidine against Enterococcus faecalis (E. faecalis) is controversial. The aim of the current study was to compare the antibacterial efficacy of Propolis and chlorhexidine as an intracanal medicament against E. faecalis in extracted human permanent teeth. The focused question was, “Does Propolis show better antibacterial efficacy than Chlorhexidine (CHX) as an intracanal medicament against E. faecalis in extracted human permanent teeth?”. Databases including PubMed/Medline, Scopus, EMBASE, ISI-Web of Science were searched from 1990 to August 2020 using different combinations of the following keywords: “Propolis”, “Intracanal medicament”, “E. faecalis”, “Antibacterial activity” and “Chlorhexidine”. Ten studies fulfilling inclusion criteria were considered for qualitative analysis, followed by quantitative analysis of eight studies. Heterogeneity was calculated for colony forming units (CFU) of E. Faecalis using the Chi-square test and I2 statistics. Forest plots were computed reporting standard mean difference (SMD) of outcomes and 95% confidence intervals. The overall mean difference for CFU of E. faecalis showed a statistically significant difference between the antibacterial efficacy of Propolis and CHX (SMD = 3.20 [1.70, 4.69] Z = 4.20; p < 0.001). CHX showed superior antibacterial efficacy against E. faecalis compared to Propolis.

Abstract Objective To evaluate the perception of rheumatologists regarding the recommendations of the Brazilian Consensus for detection of Autoantibodies (BCA) on HEp-2 Cells by Indirect Immunofluorescence assay (IFA) and how BCA recommendations help in clinical practice. Methodology A structured questionnaire regarding the BCA recommendations for detection and interpretations of autoantibodies in HEp-2 cells was applied to randomly selected rheumatologists. The results were tabulated using the Microsoft® Excel program, expressed as a simple percentage and the dichotomous data were analyzed using the Chi-square test and the Epi Info® program. Results Four hundred fuorteen rheumatologists participated in the study: 70% of them considered their knowledge of the HEp-2 IFA test satisfactory or excellent, and 43% said they knew the BCA recommendations in general, without distinguishing the edition of the BCA to which they refer. The Revista Brasileira de Rheumatologia/Advances in Rheumatology was the means of dissemination most consulted by specialists (50%). According to the rheumatologists’ opinion, the most relevant pattern was the homogeneous nuclear (78%) and 65% stated they were satisfied with the BCA recommendations at a level of satisfaction greater than or equal to 80%. There was no significant difference in the perception of rheumatologists from the several Brazilian geographic regions. Conclusion Brazilian rheumatologists are aware of the BCA guidelines and most are satisfied with the content published, considering that the BCA recommendations assist positively in the clinical practice. Most rheumatologists recognize the patterns associated with rheumatic autoimmune diseases and have used BCA recommendations to interpret the results of the HEp-2 IFA test.

Background: Although various technologies are used to evaluate driving skill, there are some limitations such as the limited range of the monitor and the possible risk of causing cybersickness. The purpose of this study is to investigate differences in the hazard perception and cybersickness experienced between novice and experienced drivers measured in a VR hazard perception test with a head-mounted display (HMD). Methods: The novice (n = 32) and the experienced drivers (n = 36) participated in the hazard perception test through the VR of an HMD. Results: The total number of identified hazards was 1071 in the novice drivers and 1376 in the experienced drivers. Two of the hazards appeared to be only identifiable through the HMD. A chi-square test revealed that experienced drivers were more likely to identify the hazards than the novice drivers (p < 0.05). The novice drivers appeared to identify “hazard prediction of the current behavior of other road users” more than other hazard types, unlike the experienced group. The Simulator Sickness Questionnaire scores indicated no significant difference in the different age or gender groups (p > 0.05). Conclusion: Our results suggest that the VR hazard perception test may be useful for evaluating patients’ driving skills.

The use of email and fax communications has increased dramatically over the last decade. They are now commonplace methods of information exchange. Most research involving questionnaires has used postal mail to deliver and return the surveys from recipients who might not otherwise be reached through live administration. A frequent methodological issue with mail surveys is low levels of return rates. The present research compared the return rates of a survey that was sent by mail, email or fax. Participants could return the survey by any of the same three methods. The results showed that postal mail and email exhibited higher return rates than facsimiles and that the method of return tended to be the same method in which the questionnaire was originally sent. Implications of these results for survey research are discussed.
