Summary. Posture is a feature that allows us to understand the biological, mechanical, mental and emotional functioning of human beings; the positioning of the head on the body meets the physiological requirements of breathing, hearing, vision and balance, and the stimuli to which the children are subjected determine to a great extent the postural balance they will have in adulthood. The aim of the present study was to determine the relationship between the position of the head during the use of electronic devices and bipedal position in the sagittal plane in children aged 6 to 10 years. It is a cross-sectional study of 56 children enrolled in a private school in Bogotá, mean age of 8.2 + 2 years whose participation was voluntary. The position of the child in the sagittal plane and the position of the head during the use of electronic devices were evaluated by means of photographs. Correlation measurements and non-parametric tests were used for comparison of medians. 69% of the participants presented advanced head, the average distance from cervical 1 (C1) to the perpendicular traced (P) in children with head forward was 5 cm. The average flexion of the head during the use of the digital tablet was 30 ° while with the computer it was 20 ° (p = .005). No relationship was found between head positions and posture in the sagittal plane in the sample evaluated; a significant difference was found between head flexion during tablet and computer use.Resumen. La postura es una característica que permite entender el funcionamiento biológico, mecánico, mental y emocional de los seres humanos; el posicionamiento de la cabeza sobre el cuerpo cumple con requisitos fisiológicos de respiración, audición, visión y equilibrio, además los estímulos a los que los niños están sometidos determinan en gran medida el equilibrio postural que tendrán en la edad adulta. El objetivo del presente estudio era determinar la relación entre la posición de la cabeza durante el uso de dispositivos electrónicos y la postura en bípedo en el plano sagital en niños de 6 a 10 años. Se trata de un estudio transversal realizado en 56 niños escolarizados en un colegio privado de Bogotá, edad promedio de 8.2 + 2 años cuya participación fue voluntaria. Se evaluó la postura del niño en el plano sagital y la posición de la cabeza durante el uso de dispositivos electrónicos por medio de fotografías. Se utilizaron medidas de correlación y pruebas no paramétricas para comparación de medianas. El 69% de los participantes presentó cabeza adelantada, la distancia promedio desde la cervical 1 (C1) hasta la perpendicular trazada (P) en los niños con cabeza hacia adelante fue de 5 cm. El promedio de flexión de la cabeza durante el uso de la tableta digital fue de 30° mientras que con el computador fue de 20° (p = .005). No se encontró relación entre las posiciones de la cabeza y la postura en el plano sagital en la muestra evaluada; se encontró una diferencia significativa entre la flexión de la cabeza durante el uso de la tableta y el computador.

Abstract Background Gaining proficiency in Bharatanatyam dance form necessitates maintenance of different postures for prolonged duration. These repetitive movements place tremendous physical demands on the body at young age and may alter the postural profile of the dancer. The study aimed to evaluate the differences in terms of posture between female Bharatanatyam dancers and age-matched non-dancers. A cross-sectional study was conducted in 40 female Bharatanatyam dancers and 40 age-matched female non-dancers in the age group of 18 to 30 years. Analysis of erect standing posture of dancers and non-dancers was conducted in a reserved environment using a photogrammetric method. Static photographs of the subjects were taken in the sagittal plane. The measurement of the angles of the digitized photographs was performed using KINOVEA 0.8.15 software. Head protrusion angle, cervical lordosis angle, thoracic kyphosis angle, lumbar lordosis angle, and pelvic tilt angle were evaluated. Results There was no significant difference between the dancers and non-dancers with respect to head protrusion angle (p = 0.081), cervical lordosis (p = 0.15), and thoracic kyphosis (p = 0.33). Significant differences were identified between the dancers and non-dancers for lumbar lordosis (p = 0.00) and pelvic tilt (p = 0.00) using independent t test with dancers. Higher values of lumbar lordosis and pelvic tilt were observed in dancers. Conclusion Increased lumbar lordosis and anterior pelvic tilt were observed in Bharatanatyam dancers as compared to non-dancers. Hence, it is vital to establish preventive measures like postural re-education, muscular balance, and flexibility to prevent erroneous postural patterns capable of causing pain and injuries.

Determining gender is one of the most important procedure in forensics. Teeth are made of the most enduring mineralized tissues in the body, as such, they have an extraordinary resistance to putrefaction and the effects of external agents (physical, thermal, mechanical, chemical or biological) which makes them invaluable material for anthropological, genetic, odontologic and forensic examinations.i)To assess the degree of sexual dimorphism in maxillary canine using maxillary canine index, maxillary first molar and central incisor using mesiodistal (MD) and buccolingual/buccopalatal (BL) dimensions of the crown. ii) To determine the accuracy of maxillary canine index, first molar and central incisor dimensions (mesiodistal and buccolingual/buccopalatal) in determining sex.This study consisted of total 30 participants (males=15, females=15) of age group ranging from 20 to 35 yrs. Measurement of dimensions of selected teeth were performed on maxillary cast using digital Vernier caliper, resolution 0.01mm. Data thus obtained were analyzed statistically.The mean values of all the measurements in males were greater than females. There was statistical significant difference in mean value of bucco-lingual width of molar, mesiodistal width of canine (on left side, right side and average) and the inter-canine distance between males and females. The buccolingual width of molar showed the highest % of sexual dimorphism (5.33%) and the mesiodistal width of molar showed the least % of dimorphism (0.7%). Bucco-lingual width of molar posed the highest prediction accuracy for gender determination. We conclude that buccolingual width of maxillary first molar can be used to predict the gender when only teeth of maxillary arch are available for forensic examination.

Abstract Background: Lupus is an inflammatory and autoimmune disease that involves various tissues and organs of the body. Identification of diagnostic elements to rapid identification of seronegative lupus cases is very important in order to prevent morbidity and progression of disease. This study aimed to compare clinical and laboratory findings of seropositive cases with seronegative lupus patients. Methods: This cross-sectional analytic study was performed on 43 children (17 seronegative and 26 seropositive) with lupus who were admitted to Ali Asghar Hospital during 2007-2017. Seropositive patients had anti-nuclear antibody (ANA) titration >1/80, while seronegative patients had ANA titration <1/80 (at the time of disease diagnosis). Clinical and laboratory findings were compared between two groups.Results: Serositis in patients with ANA- was significantly higher than ANA+ (41.17% vs. 23.07%; p = 0.042). ANA- group had higher autoimmune disease history than ANA+ group (42.85% vs. 15.0%; p = 0.041). The family history of the disease in the ANA- group was greater than ANA+ group (50% vs. 23.52%). The percentage of hypertensive patients in ANA- group was higher than ANA+ group (52.94% vs. 26.92%; p = 0.037). Neurologic symptoms in ANA+ and ANA- groups were 38.46% and 17.64%, respectively (p = 0.043). The frequency of patients with thrombocytopenia in ANA+ group was significantly greater than ANA- group (32% vs. 12.5%; p=0.041). There was no significant difference in other clinical and laboratory findings between two groups. Conclusion: Seronegative lupus patients had higher percentage of musculoskeletal symptoms, autoimmune disease history, familial history of disease, and hypertension, while neurological and thrombocytopenia symptoms were higher in seropositive patients compared to seronegative cases. Therefore, evaluation of these factors can be helpful to diagnosis of seronegative patients.

Introduction: Tuberculosis infection caused by Mycobacterium tuberculosis is one of the most common infectious diseases, especially in countries such as Iran. The course of treatment and the number of drugs used vary depending on the severity of the disease and the parts of the body involved. The resistant tuberculosis to treatment has increased in recent years. Thus, this study was conducted to investigate the frequency distribution of response to treatment of patients with tuberculosis in Sirjan, Iran. Methods: This descriptive cross-sectional study investigated all patients with tuberculosis in Sirjan city who had referred to health centers during the years 2011-2019. The data collection tool was a pre-prepared checklist that included information on age, sex, sputum smear results, sputum culture results, diabetes, patients' nationality, drug side effects, and response to treatment. Finally, data was entered into SPSS version 22, and analyzed. Results: In this study, the overall response rate was 83% and the mortality rate was 10%. Between the frequency distribution of response to treatment in terms of gender, age, sputum smear results, sputum culture results, patients' nationality and diabetes was not statistically significant difference. Also, no statistically significant difference was found between the frequency distribution of pulmonary TB treatment response in terms of drug allergy, drug hepatitis and other drug side effects. Conclusion: According to results, can be concluded that none of the variables: age, sex, smear and culture result, and history of diabetes have no an effect on response to treatment and mortality of tuberculosis.

BACKGROUND WHO has declared Coronavirus disease 2019 (Covid-19) as a pandemic. Covid-19 leads to sickness and death. Human serum albumin (HSA) is the most common circulating protein in the body having oncotic as well as non-oncotic properties. The role of albumin in death among Covid-19 subjects, especially in this part of the country has not been frequently reported. The aim of the study was to analyse the role of serum albumin level as prognostic marker for Covid-19 positive patients. METHODS The present study was conducted in the department of Medicine at Chhatrapati Shivaji Subharti Hospital, Subharti Medical College, Meerut, UP. The study comprised of 100 subjects who were Covid positive from May 2020 to July 2020. A detailed explanation was given to all the participating respondents regarding the study and their contribution to it. Covid-19 was diagnosed on the basis of the WHO interim guidelines. A questionnaire was prepared to collect the patients’ demographic profile. Patients date of admission and discharge was recorded along with the outcome i.e., whether patient expired or survived. Patients’ diagnosis was identified along with the comorbidity (if present). Laboratory investigations comprised of CBC and serum albumin detection. Data so collected was tabulated in an excel sheet, under the guidance of statistician. Collected data was analysed using Statistical Package for the Social Sciences (SPSS) software version 24 and the tests used were t test and Fisher’s exact test and the level of significance was set at p < 0.05. RESULTS The study comprised of 100 subjects, out of which 45 were males and 55 were females. The overall mean age of the study subjects was 37.52 years. In our study, mortality was 35.29 %, 9.33 % and 85.7 % of the subjects having Covid-19+ type 2 diabetes (T2DM), only Covid-19 and Covid-19+ hypertension respectively with statistically significant difference as p < 0.05. Albumin level was significantly lower in expired patients (2.99) as compared to survivors (3.85) as p < 0.05. Hospital stay was also higher in expired patients. CONCLUSIONS Covid-19 patients had low serum albumin levels and that might play a role in the survival of patient. KEYWORDS Covid-19, Mortality, Albumin

The purpose of this study was to investigate the level of renal function knowledge of primary school pupils in Greece. We conducted a cross-sectional study with a convenience sample of 220 pupils, coming from the 5th and 6th grades of general education schools. A questionnaire consisting of 11 questions was developed from scratch. However, based on an analysis of Cronbach’s alpha values obtained when individual questions were deleted, two questions were removed from the analysis, and only nine remained for analysis and participated in the calculation of the knowledge score. Moreover, the gender and daily habits of pupils regarding water consumption and frequency of urination were recorded. Pupils had a high percentage of correct knowledge about the number of kidneys (95.2%), whether a child may have problems with the kidneys (85.5%) and whether a person can survive with one kidney (68.5%). Low levels of knowledge were observed in the function and role of the kidneys (36.4%), as well as the part of the body where the kidneys are located (30.9%). The median (interquartile range (IQR)) total knowledge score was 6 (5–7), with no difference detected between genders (p = 0.135). A statistically significant difference between pupils of 5th and 6th grades was found but the difference did not seem to be clinically significant (p = 0.035). The present research demonstrates that pupils’ knowledge of renal function and the protection of their kidneys needs improvement.

Background: A well-fitting and comfortable ischial containment socket relies on accurately replicating the transverse plane angle of the ischium and ischial ramus angle, inside the medial socket brim. Prediction of the ischial ramus angle, may provide a way to determine the ischial ramus angle without in vivo measurement. Objectives: To determine the accuracy with which the ischial ramus angle could be predicted and identify which variables contributed significantly to the prediction. Study design: Cross-sectional study. Methods: Computed tomography scans were randomly sampled from a cadaveric database (n = 200). Standard multiple regression models were developed to predict the ischial ramus angle based on pelvic measures. Results: The regression model explained 10.5% of the variance in ischial ramus angle (p = 0.018). The standard error of the estimate was 11.32°. While regression models by sex explained a larger proportion of the variance, the resulting accuracy was not improved. Conclusion: The regression models explained a small proportion of variance in ischial ramus angle. The average error associated with the prediction was too large to accurately predict the ischial ramus angle for use in clinical practice. Contrary to commonly held beliefs, there was no statistically significant difference in ischial ramus angle between sexes. Clinical relevance Prediction of ischial ramus angle does not have sufficient accuracy to be clinically useful, but descriptive data may help clinicians identify casting errors and correct these in a plaster positive, knowing that the average ischial ramus angle was 32.65°±5.59° (relative to mid-sagittal plane) and does not vary between sexes.

Background: Obesity is a serious health problem, it increases heart-related diseases and its prevalence continues to increase due to genetic and lifestyle influences. This study aims to evaluate the hematological parameters of obese individuals based on gender in the Omisanjana region of Ado Ekiti, Ekiti state. Nigeria. Materials and Methods: The research is based on a cross-sectional study of obese and non-obese individuals in hospitals. The study was carried out in the Omisanjana area of ​​Ado Ekiti, Ekiti state. Fifty (50) obese individuals and fifty (50) apparently non-obese individuals were recruited as controls and participated in the study. The data are shown in the table and are expressed as mean ± standard deviation, and are analyzed using the Student's t test of the statistical software package for social sciences (SPSS, version 20.0), and the level of significance is established at p≤ 0.05. Results: The results showed no significant difference in PCV (p=0.3783), WBC (p=0.501), LYM (p=0.149), GRAN (p=0.336), MID (p=0.242), ,RBC (p=0.243), HGB (p=0.086), HCT (p=0.323), MCV (p=0.943), MCH p=0.097), MCHC (p=0.922), PLT (p=0.941), when compared between obese individuals and non-obese individuals based on sex respectively. Conclusion: The study showed no statistically significant changes, and it may be because there are no significant changes in the physiological factors and the growth factors of the precursor cells in the bone marrow, so the body mass index (BMI) has no effect on hematological parameters.
