ABSTRACT The KIDMED Index is frequently used to evaluate adherence to the Mediterranean Dietary Pattern among children and adolescents, through 16 questions with the associated total score ranging from -4 to 12. However, in the authors’ best knowledge, the psychometric properties of this index had not yet been investigated in Portugal. Thus, the main purpose of the present study was to investigate the reproducibility and the validity of the KIDMED Index in a sample of 185 Portuguese adolescents. The reproducibility was tested by comparing the application of the KIDMED Index at two different times (two-week interval), using McNemar test and Kappa statistics. There was moderate agreement (κw = 0.591, 95% CI = 0.485-0.696) and no significant change (p-value = 0.201) in the KIDMED Index classification, between the two applications. The validity was explored by comparing the results obtained by the KIDMED Index and by the average of 3-days Dietary-Record (DR), using Spearman’s correlation coefficient and Kappa statistics. There was weak correlation (ρ = 0.317; p-value < 0.001) and slight agreement (κw = 0.167, 95% CI = 0.071-0.262) between the KIDMED Index classification and the 3-days DR-derived KIDMED score; and moderate correlation (ρ = 0.423; p-value < 0.001) and fair agreement (κw = 0.344, 95% CI = 0.202-0.486) between the terciles of the KIDMED Index and the Mediterranean Adequacy Index scores. The results suggested an acceptable reproducibility and validity of the Portuguese version of the KIDMED Index, in alignment with the few studies investigating psychometric properties of this index in other countries.

No prior studies have examined the reliability properties of the 16-item Mediterranean Diet Quality Index (KIDMED) questionnaire among young adults from a non-Mediterranean country. The objective of this study was to determine the psychometric properties in terms of the reliability and validity of the KIDMED questionnaire in young adults from Colombia. A cross-sectional validation study was conducted among 604 Colombian college students (47.51% men and 52.48% women; mean age of 21.60 ± 2.02 years). Kappa statistics were used to assess the reliability of the KIDMED questionnaire. A categorical principal components analysis was used to determine validity. Based on the KIDMED score, 58.4% of students had a good adherence to the Mediterranean diet (MedDiet). Good agreement in the general score of the questionnaire was observed (κ = 0.727, 95% confidence interval = 0.676 to 0.778, p < 0.001). A five-factor model was identified which explained almost 51.38% of the variability, showing the multidimensionality of the questionnaire. In conclusion, this study provides reasonable evidence for the reliability and validity of the KIDMED questionnaire for assessing adherence to MedDiet in college students within a Latin American country. The evaluation of the psychometric properties of this tool in early adulthood and in a non-Mediterranean country will be useful in clinical practice and epidemiological research, since practitioners and health researchers now have a valid and reliable short scale.

This study provides comprehensive validation of the 14-item Mediterranean Diet Adherence Screener (14-MEDAS) in an adult population from Greece (GR), Portugal (PT), Italy (IT), Spain (SP), Cyprus (CY), Republic of North Macedonia (NMK), and Bulgaria (BG). A moderate association between the 14-MEDAS and the reference food diary was estimated for the entire population (Pearson r = 0.573, p-value < 0.001; Intraclass Correlation Coefficient (ICC) = 0.692, p-value < 0.001) with the strongest correlation found in GR, followed by PT, IT, SP, and CY. These results were supported by kappa statistics in GR, PT, IT, and SP with ≥50% of food items exhibiting a fair or better agreement. Bland–Altman analyses showed an overestimation of the 14-MEDAS score in the whole population (0.79 ± 1.81, 95%Confidence Interval (CI) 0.61, 0.96), but this value was variable across countries, with GR, NMK, and BG exhibiting the lowest bias. Taking all analyses together, the validation achieved slightly better results in the Mediterranean countries but a definitive validation ranking order was not evident. Considering growing evidence of the shift from Mediterranean Diet (MD) adherence and of the importance of culture in making food choices it is crucial that we further improve validation protocols with specific applications to measure and compare MD adherence across countries and to relate it to the health status of a specific population.

Pulp Vitality

Background: The pulp tissue is confined within hard tissue boundaries and cannot be examined directly for health evaluation. Hence, its assessment is usually based on sensibility tests. Accurate diagnosis of the pulpal status requires evaluation with combination of sensibility tests. The objective of this study was to assess the mutual agreement between the electric pulp test and cold test in determining pulp vitality. Methods: Total 106 patients, aged 18 to 30 years, attending the dental OPD of Operative Dentistry/Endodontics department; Dr. Ishrat-ul-Ibad Institute of Oral Health Sciences, Karachi were selected for the study. The cold and electric pulp tests were used to determine the presence or absence of tingling sensation. Teeth were marked as vital in presence and non-vital in absence of any tingling or painful response. Agreement between these two tests was calculated using SPSS-18. To calculate the mean and standard deviation, descriptive statistics were applied for quantitative variables. For qualitative variables, frequencies and percentages were calculated. Kappa statistics was applied for agreement between electric pulp and cold test. Results: The cold test showed that 70.8% of the teeth were vital and 29.2% were necrotic. The electrical pulp test showed that 74.5% were vital and 25.5% were necrotic. The outcome showed 83.0% agreement between the tests; with kappa value of 0.574 which provided sufficient agreement with p-value=0.000. Conclusion: There was a high agreement found between the cold test and electric pulp test. Assessment of pulp vitality would be more accurate when EPT and Endo frost are used in combination.

Abstract Background The dietary nutritional status of the lactating mothers is related to maternal health and has a significant impact on the growth and development of infants through the secretion of breast milk. The food frequency questionnaire (FFQ) is the most cost-effective dietary assessment method that can help obtain information on the usual dietary pattern of participants. Until now, the FFQs have been used for different populations in China, but there are few FFQs available for the lactating mothers. We aimed to develop a semi-quantitative, 156-item FFQ for the Chinese lactating mothers, and evaluate its reproducibility and relative validity. Methods A total of 112 lactating mothers completed two FFQs and one 3-d dietary record (3DR). The first FFQ (FFQ1) was conducted during postpartum at 60–65 days and the second FFQ (FFQ2) during subsequent follow-up at 5 weeks. The 3DR was completed with portion sizes assessed using photographs taken by the respondent before and after eating (instant photography) 1 week after FFQ1. Results For reproducibility, the Spearman’s correlation coefficients for food ranged from 0.34 to 0.68, and for nutrients from 0.25 to 0.61. Meanwhile, the intra-class correlation coefficients for food ranged from 0.48 to 0.87, and for nutrients from 0.27 to 0.70. For relative validity, the Spearman’s correlation coefficients for food ranged from 0.32 to 0.56, and for nutrients from 0.23 to 0.72. The energy-adjusted coefficients for food ranged from 0.26 to 0.55, and for nutrients from 0.22 to 0.47. Moreover, the de-attenuation coefficients for food ranged from 0.34 to 0.67, and for nutrients from 0.28 to 0.77. The Bland-Altman plots also showed reasonably acceptable agreement between the two methods. Conclusions This FFQ is a reasonably reproducible and a relative valid tool for assessing dietary intake of the Chinese lactating mothers.

Methods: Descriptive, Cross Sectional Survey was conducted in the Department of Pathology, Fatima Memorial Hospital, Lahore during 6 months (May 11, 2016 to Nov 11, 2016). Using non-probability consecutive sampling, 105 cases were included in this study as per the inclusion and exclusion criteria. 10% buffered formalin was used to fix the sepecimens. Gross examination and staining with Hematoxylin and Eosin was done. The cases were diagnosed by a histopathologist. IHC staining Ki67 was performed, assessed by histopathologist and the data was recorded on the proforma. Results: The mean age was 27.79±5.81 years with minimum and maximum ages of 18 years and 42 years respectively. The histopathological findings showed hydatidiform mole in 41 (39%) women and hydropic abortus in 64(61%) women. The Ki67 was reported to be >25 in 41(39%) patients and less than or equal to 25 in 64(61%) patients. The agreement of differentiation in the two types for histopathology and Ki67 was found in 101(96.2%) patients. Kappa statistics showed 92% (p-value= 0.000) strength of agreement between histopathology and Ki67. Conclusion: There is high degree of agreement between Ki67 and histopathology for differentiation of hydatidiform mole and hydropic abortus. So Ki67 can be used as an adjacent in histopathologic diagnosis of hydatidiform mole in difficult cases. MeSh words: Hydatidiform Mole, Immunohistochemistry, Ki-67 Antigen

Reasons for living are protective factors against suicidal behavior in adolescents. One of the most useful measures to assess them is the Reasons for Living Inventory for Adolescents (RFL-A) developed by Osman et al. The goal of this study was to examine the psychometric properties of its Portuguese version of the RFL-A. To this end, we recruited 512 high school adolescents (mean age = 16.7 years), who completed the RFL-A, a Suicidal Ideation Questionnaire, and a hopelessness scale. Exploratory factor analysis replicated the original five-factor model and confirmatory factor analysis obtained satisfactory adjustment values. The RFL-A shows good reliability (internal consistency and temporal stability) as well as good convergent, discriminant, and concurrent validities. These results indicate that the RFL-A is a valid and reliable measure to study protective factors against suicidal behaviors in Portuguese adolescents.

Abstract Background Emergency care continues to be a challenge, since patients’ arrival is unscheduled and could occur at the same time which may fill the Emergency Department with non-urgent patients. Triaging is an integral part of every busy ED. The Canadian Triage and Acuity Scale (CTAS) is considered an accurate tool to be used outside Canada. This study aims to identify the chosen triage level and compare the variation between registered nurses, pediatric and adult emergency residents by using CTAS cases. Method This study was conducted at King Abdulaziz Medical City,Saudi Arabia. A cross-sectional self-administered questionnaire was used, and which contains 15 case scenarios with different triage levels. All cases were adopted from a Canadian triage course after receiving permission. Each case provides the patient’s symptoms, clinical signs and mode of arrival to the ED. The participants were instructed to assign a triage level using the following scale. A non-random sampling technique was used for this study. The rates of agreement between residents were calculated using kappa statistics (weighted-kappa) (95%CI). Result A total of 151 participants completed the study questionnaire which include 15 case scenarios. 73 were nurses and 78 were residents. The results showed 51.3, 56.6, and 59.9% mis-triaged the cases among the nurses, emergency residents, and pediatric residents respectively. Triage scores were compared using the Kruskal Wallis test and were statistically significant with a p value of 0.006. The mean ranks for nurses, emergency residents and pediatric residents were 86.41, 73.6 and 59.96, respectively. The Kruskal Wallis Post-Hoc test was performed to see which groups were statistically significant, and it was found that there was a significant difference between nurses and pediatrics residents (P value = 0.005). Moreover, there were no significant differences found between nurses and ER residents (P value> 0.05). Conclusion The triaging system was found to be a very important tool to prioritize patients based on their complaints. The results showed that nurses had the greatest experience in implementing patients on the right triage level. On the other hand, ER and pediatric residents need to develop more knowledge about CTAS and become exposed more to the triaging system during their training.

Abstract BACKGROUND: P16/INK4a and Ki-67 have emerged as important biomarkers for the detection of high-risk human papilloma virus (HR-HPV) associated dysplastic changes in the cervical biopsy samples. The increasing inter- and intra-observer variability in the diagnosis of dysplastic lesions and immature squamous metaplasia on histopathology has led to the advent of these biomarkers. This study was taken up with an aim to study their role in increasing the diagnostic accuracy in equivocal cases on histopathology. MATERIALS AND METHODS: Fifty cervical biopsy specimens were stained with p16/INK4a and Ki-67 consisting of 10 cases each of cervical intraepithelial neoplasia (CIN I/II/III) along with five cases of squamous metaplasia. Histopathological diagnosis was considered as the gold standard. Statistical analysis was done by kappa statistics, and P value was calculated. RESULTS: The sensitivity and specificity of p16/INK4a and Ki-67 were 76.2%, 87.5%, 90.5%, and 87.5%, respectively. The overall agreement of both the immunostains with histopathological diagnosis was statistically significant (P < 0.05) and the diagnostic accuracy improved when both the stains were used in conjunction. CONCLUSION: Ki-67 and p16/INK4a can be used as complimentary tests in differentiating dysplastic and nondysplastic lesions and help in confirming the histopathological diagnosis. They aid in recognition of dysplasias caused by HR-HPV, which have higher tendency to progress to neoplasia. However, further research is advocated before the widespread use of these markers for screening of dysplasias.

The Mediterranean diet (MD) and other lifestyle characteristics have been associated with well-being, a broad multiparameter concept that includes individual’s subjective assessment of their own well-being (SWB). Some studies have suggested that diet influences SWB, thus, this work aimed to add novel information on the association of MD and SWB in a sample of Portuguese adults. Data on sociodemographic, economic, lifestyle, diet, and SWB were collected through a self-filled online questionnaire. MD adherence was assessed by the Mediterranean Diet Adherence Screener (MEDAS) score. Results showed a moderate adherence to the MD in 490 Portuguese adults (mean MEDAS of 7.4 ± 2.1). A higher MD adherence was found to be significantly positively associated with women, employed individuals, a higher number of meals per day, and those with frequent contact with nature (p-value < 0.0025, using Bonferroni adjustment). As a novelty, this study divided the participants into low SWB, medium SWB, and medium to high SWB profiles (3.9 ± 1.0; 6.2 ± 1.0; 8.2 ± 1.3, respectively; p-value < 0.05), which reported significantly increasing MEDAS scores (6.5 ± 2.1; 7.3 ± 2.1; 7.8 ± 1.9; respectively, p-value < 0.05).
