Introduction. Chest X-ray (CXR) is used for the initial triage of patients with suspected COVID-19. Studies of CXR scoring in the European population found a higher score in males than in females and significantly correlated with age. Because there have not been studies in the Mexican-mestizo community, we aimed to compare the differences in CXR scores between males and females and their correlation with age after controlling comorbidities like diabetes and hypertension. Materials and Methods. A retrospective study of 1000 CXR of Mexican-mestizo patients with SARS-CoV-2 infection, confirmed by RT-PCR. Significant differences between age, age groups, symptoms, comorbidities, and CXR scores between males and females used the Mann–Whitney U , Chi-square tests ( χ 2 ), and Kruskal–Wallis tests. The relationship between the total CXR score and age was measured with the Spearman rank correlation coefficient (Rs); partial correlation analysis controlled the effect of symptoms, risk factors, and comorbidities. Results. The total CXR score did not show a difference between males and females grouped by age. There was a positive, low correlation between the total CXR score and age in males, Rs = 0.260 , p < 0.001 ( N = 616 ), and in females, Rs = 0.170 , p = 0.001 ( N = 384 ). Age only explained a <9% variance of CXR severity. Rs decreased its magnitude (from Rs = 0.152 to Rs = 0.046 ) and lost its significance (change in p value from p < 0.001 to p = 0.145 ) after controlling the effect of hypertension. Conclusions. There is no significant difference in CXR score between males and females in the Mexican-mestizo population grouped by age. Hypertension cancels the significance of CXR severity with age pointing to its role in the pathophysiology of COVID-19. Further research using stratified groups by age and gender in other populations needs to be published.

Knowledge of acetabular morphometry parameters namely acetabular inclination and anteversion angles beside acetabular depth aid surgeons to accurately plan hip replacement procedure. The current hip implants designed based on Caucasian population which may not accurately match morphologic features of our population. Our objective is to determine normal acetabular morphometric parameters from CT scans of Malay patients in Hospital Universiti Sains Malaysia and compare gender and age group differences. A cross-sectional study was done within 18 months duration from November 2010 till May 2012. A total of 133 samples collected and divided into four age groups. Mean and standard deviations for all parameters were determined. No significant difference between acetabular parameters among males and females (p>0.001). Significant difference between age groups noted, mainly in group 1 (18 to 30 years) with group 4 (51 to 60 years) in all parameters. As for conclusion, no significant parameter differences between genders, hence no indication for gender or population specific hip implants. Significant differences noted when parameters compared between age groups, especially between the two extremes of age groups.

Infective lung disease is a spectrum of pulmonary disorders with high prevalence in clinical practice. In the last decade, many studies focused on the clinical usefulness of lung ultrasound (LUS) in the management of patients presenting with dyspnea from infective lung disease. We report data on the methodological and standardized use of bedside LUS in the differential diagnosis of patients with acute dyspnea from infective lung diseases. We performed a cross-sectional study in 439 patients (160 women and 279 men, mean age 64.2 ± 11.5 years, age range 23–91 years) with infective lung diseases. A bedside LUS with a convex probe and chest X-ray were performed in all subjects. Chest CT was performed in a subgroup of patients, as clinically needed. We observed a statistically significant difference in the percentage of pleural effusion and pulmonary consolidation assessed by LUS, compared to X-ray (52.7 vs. 20%, respectively, p &lt; 0.05; 93.6 vs. 48.2%, p &lt; 0.001). The majority of the consolidations detected by LUS were mixed, hypo- and hyperechoic, lesions, with air bronchogram in 40% of cases. All findings assessed by LUS were confirmed by chest CT, when performed. We describe the actual role of LUS in the assessment of patients with infective lung disease. It has higher sensitivity compared to chest X-ray in the detection of pleural effusion. Consolidations from infective lung disease have mostly mixed echogenicity by LUS.

Background: Gender may alter African Americans’ vulnerability to discrimination. The type of outcomes that follow exposure to discrimination may also be gender-specific. Although teacher discrimination is known to deteriorate school performance, it is yet unknown whether male and female African American youth differ in the effect of teacher discrimination on school performance. Objective: This cross-sectional study explored the moderating role of gender on the effect of teacher discrimination on school performance in a national sample of African American youth. Methods: The National Survey of American Life-Adolescent Supplement (NSAL-A) enrolled a nationally representative sample (n = 810) of 13–17-year-old African American youth. Demographic factors, socioeconomic status, teacher discrimination, and school performance (grade point average, GPA) were measured. Linear multivariable regression models were applied for data analysis. Results: Males and females reported similar levels of perceived teacher discrimination. In the pooled sample, higher teacher discrimination was associated with lower school performance among African American youth (b = −0.35; 95% confidence interval (CI) = −0.49 to −0.22). Gender interacted with perceived teacher discrimination (b = 12; 95% CI = 0.24–2.02), suggesting a significant difference between males and females in the magnitude of the association between perceived teacher discrimination and GPA. In stratified models, perceived teacher discrimination was associated with worse school performance of females (b = −12; 95% CI = −0.03 to −2.78) but not males (b = 0.01; 95% CI = −0.07 to 0.08). Conclusion: In line with previous studies, gender was found to alter the vulnerability of African American youth to perceived discrimination. African American boys and girls may differ in their sensitivity to the effects of teacher discrimination on school performance.

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

The WHO END TB strategy requires ≥90% case detection to combat tuberculosis (TB). Increased TB case detection requires a more sensitive and specific screening tool. Currently, the symptoms recommended for screening TB have been found to be suboptimal since up to 44% of individuals with TB are asymptomatic. The chest X-ray (CXR) as a screening tool for pulmonary TB was evaluated in this study, as well as its incremental yield in TB diagnosis using a cross-sectional study involving secondary analysis of data of 4512 consented/assented participants ≥15 years who participated in the Uganda National TB prevalence survey between 2014 and 2015. Participants with a cough ≥2 weeks, fever, weight loss, and night sweats screened positive for TB using the symptoms screening method, while participants with a TB defining abnormality on CXR screened positive for TB by the CXR screening method. The Löwenstein-Jensen (LJ) culture was used as a gold standard for TB diagnosis. The CXR had 93% sensitivity and 65% specificity compared to LJ culture results, while symptoms had 76% sensitivity and 31% specificity. The screening algorithm involving the CXR in addition to symptoms led to a 38% increment in the yield of diagnosed tuberculosis. The number needed to screen using the CXR and symptoms screening algorithm was 32 compared to 45 when the symptoms are used alone. Therefore, the CXR in combination with symptoms is a good TB screening tool and increases the yield of diagnosed TB.

Objective: The aim of the study is to assess knowledge, attitude and practices of dental implants among dental interns in Saudi Arabia Materials and Methods: A self-designed, close-ended questionnaire was distributed among 205 interns chosen by stratified random sampling technique. The questionnaire consisted of 28 items pertaining to demographic characteristics, knowledge and practices of dental implants. Responses were coded and entered into spreadsheet software (Microsoft Excel 16.0.) and analyzed using Statistical Package for Social Sciences (SPSS, IBM Version 22.0) and contingency tables and chi-square test (χ2). Results: The majority of the participants were males (64.4%), between 24-26 years of age (64%) and had a GPA between 4-5 (63.4%). The majority of the participants gained knowledge of dental implants through theoretical lectures (98.5%), and most of them (80%) knew, what material, an implant was made up of. Almost all participants (91.7%) knew that dental implants had surface modifications. Most (64.4%) believed that case selection is the most important criteria for the success of dental implant therapy, and this differed significantly among participants with respect to GPA (p=0.03). Many participants (60%) believed that the most important advantage of dental implants over fixed prosthesis is that reduction of adjacent tooth is not needed, and this differed significantly between males and females (p=0.026). There was a significant difference (p<0.001) between males and females when it came to confidence in independently restoring teeth using dental implants. 63% of the participants were confident to use dental implants in their future practice. Conclusion: Knowledge of dental implants among dental interns is satisfactory, but this study reveals that participants lack practical experience and would like to acquire more clinical skills. Limitations: The response rate of participants from each university was low, which made comparisons between different universities difficult because sample size from some universities was very small, which could not produce statistically accurate results.
