Abstract Background: Differences in far interpupillary distance (IPD) in Turkish and Azerbaijani adults of the same ethnic background from different age groups were examined to investigate the effects of ethnicity, genetics, geography, and environmental factors on IPD. Methods: A total of 1,400 healthy individuals aged ≥18 years were enrolled. The far IPD of each individual was determined in both communities. IPD data for 700 subjects in Azerbaijan and 700 subjects in Turkey was analyzed. Males and females were divided into six age ranges: 18–24, 25–34, 35–44, 45–54, 55–64, and ≥65 years. Far IPD data in Turkey and Azerbaijan was collected using two types of autorefractometers: Topcon RM 8800 and Topcon TRK-2P.Results: The mean age of the 700 subjects in Turkey was 44.5 ± 17.6 years. The mean IPD was 62.1 ± 3.7 mm. The mean IPD in females was 61 mm, which was less than males (63 mm) (P < 0.05). The mean age of the 700 Azerbaijani subjects was 44.0 ± 15.6 years. The mean IPD of the subjects was 65.0 ± 3.1 mm. The mean IPD (64 mm) in females was significantly lower than the mean IPD (66 mm) in males (P < 0.05). Differences in IPD between age groups in both communities were statistically significant (P < 0.05). The mean IPD in all age groups in the Azerbaijani population was greater than that of the Turkish population. Compared with other ethnic groups, the mean IPD in the Azerbaijani population was remarkably high.Conclusions: When mean far IPD values in individuals aged ≥18 years in the Azerbaijani and Turkish populations were compared, statistically significant differences were observed. In Azerbaijani Turks, mean IPD values in both males and females were greater than those observed in the Turkish population in all age groups. The mean IPD values of the Azerbaijani population were greater than those of other ethnic groups when classified by both age and sex. As well as ethnicity, geographical and environmental factors influenced far IPD values.

Due to a lack of a food composition database on starch and sugars, we developed a comprehensive database on starch and seven types of sugars in commonly consumed foods (n = 2222) in Japan. Dietary record data of 368 toddlers (aged 18–35 months), 376 preschool children (aged 3–6 years), 915 schoolchildren (aged 8–14 years) and 392 adults (aged 20–69 years) were used. The mean starch intake ranged from 55.6 g/day (female toddlers) to 206.0 g/day (male schoolchildren). Irrespective of age and sex, >50% of starch was provided by rice and grains. The mean total sugar intake ranged from 46.1 g/day (female toddlers) to 68.7 g/day (male schoolchildren). In all age and sex groups, the major contributors of total sugar included sucrose (mean: 18.2–34.0 g/day), glucose (7.8–13.1 g/day), lactose (5.3–13.1 g/day) and fructose (7.6–11.1 g/day). The top food sources were dairy products (toddlers) and confectionaries (other age groups) for total sugar, confectionaries for sucrose, fruits (toddlers) and vegetables (other age groups) for glucose, dairy products for lactose and fruits (toddlers and preschool children) and vegetables (schoolchildren and adults) for fructose. In conclusion, this study clarified the starch and sugar intake in Japan and provides a foundation for future research.

This brief study investigates the development of fundamental frequency (FO) in pre-adolescent children as a function of age and sex. The children who took part in the study were divided into three age groups: 6, 8 and 10 years. Each group consisted of three males and three females. Each subject produced nine target phrases with [] in phrase-final position, which were elicited via a picture-naming task. FO was estimated for the nine target utterances and the following FO parameters were derived: mean FO for the whole phrase; FO range for the whole phrase; standard deviation values of FO for the whole phrase and mean FO for the phrase-final vowel [α:]. Results indicated that FO parameters generally decreased with age, and by age 10 years the males had lower values than the females for all four parameters. Results also indicated that the mean standard deviation of FO across the phrase was significantly higher for the females compared to that for the males.

Objectives: Seizure is the fourth most common neurological disorder in the world; it affects all age groups with equal possibility of occurrence in both males and females. Many antiepileptic drugs are available today, but its diagnosis is challenging. The present study attempted to see if seizure activities could be predicted by analyzing the pre-seizure electrical activities. The prediction may help in taking preventive measures appropriately beforehand in the individuals with seizure proneness. Material and Methods: We selected 11 generalized seizure patients and 19 control patients out of total 115 patients referred for electro-diagnostics for various reasons. EEG of the subjects recorded, segmented as per protocol, and analyzed using MATLAB and EEGLAB tools. Results: The mean energy level in alpha and beta band of the study subject was significantly lower (P = 0.04 and 0.004, respectively) as compared to the age matched control subjects. Theta and delta bands did not show any significant difference between the groups. The difference between the pre- and post-electrical seizure energy and entropy was statistically insignificant. Conclusion: The study shows that the energy level remains low in the seizure patients in the alpha and beta bands. This further goes down when electrophysiological seizure activities starts. The randomness or entropy does not alter significantly among the seizure subjects in comparison to non-seizure subjects.

Objective: Information regarding clinical characteristics and the natural course of COVID-19amongst individuals without comorbidities is scarce. We therefore conducted a retrospectiveobservational study to decipher the disease profile in two different age groups, middle-aged (40-59years) and children (up to 12 years). Method: Study was conducted by reviewing the medicalrecords of all patients in the desired age groups and excluding all those with preexisting illness(called comorbidities). Result: A total of 154 and 27 patients were enrolled and studied in themiddle-aged adults and children group respectively. Males dominated in both groups with a sex ratioof 2.9 in adults and 1.7 in children. Most of the children (92.5%) had a history of exposure from aninfected family member, while in the adult group history of contact was present in 71.4% ofpatients.62.9% of children had an asymptomatic infection which was significantly higher than 22.8%in adults. Cough and fever were the most common symptoms in both age groups, but adults weremore likely to have respiratory complaints when compared with children.11 (7.1%) patients in theadult group had severe disease while in the children group none had severe disease. Similarly in theadult group 11 patients required ICU admission, but none in the children group. The mean durationof RTPCR positivity was similar in both groups. There was 1 (0.6%) expiry in the adult groupwhereas none in children. Conclusion: Healthy individuals in both middle-aged and children grouptend to have milder disease and both harbour the virus for the almost same duration but adults aremore symptomatic in comparison to children and hence children are more likely to be potentialasymptomatic carrier and transmitter of infection.

Abstract Background and Aims Kidney size has been found to be correlated with anthropometric features and is different among different ethnicities. In this study, we used ultrasonography for measurement of kidney volumes in healthy individuals and evaluated the relationships with body height, age and gender. Method We conducted a cross-sectional observational study and evaluated 108 healthy individuals whose serum creatinine level was within reference range. Patients’ medical clinical and laboratory records were reviewed. Age, gender and height were recorded. Pearson correlation coefficients were used to evaluate the strength of association between ultrasonographic parameters with each other and with other parameters, and were expressed as r2. Variations in left and right renal dimensions between various age groups were compared using a one-way analysis of variance, followed by a post-hoc Tukey's test. Results Subjects’ age ranged from 16 to 84 years and the mean age was over 50 years. There was an equal distribution among genders. Strong and positive correlations were seen for the measured length, parenchyma thickness and also for both total and parenchymal volumes with subjects’ height for both kidneys. The strongest correlations were observed for the left and right kidney length and also for the right kidney parenchymal volume (r=0.536, p=0.001; r=0.469, p=0.001; r=0.44, p=0.001). On the opposite, most of the relations with age were negative, but week and insignificant. When we divided the study subjects into three age groups and compared them for the height, there was no significant difference among them. Regarding the parenchymal and total kidney volumes of both kidneys, the different age groups showed similar findings in the ultrasonographic measurements. The mean calculated volumes were slightly declining with age and showed the largest values in the first group of patients under 30 years and lowest values in patients over 70 years old. Ultrasonographic measurements were also compared among the two genders. Both (men and women) showed similar age (53.55 ± 18.22 vs. 50.79 ± 18.13 p= 0.430, respectively). As for the height, men were significantly taller than women (1.734 ± 0.007 vs.1.637 ± 0.005, p= 0.001). The kidney length, volume and parenchymal volumes of both kidneys were significantly larger in men. Conclusion Renal length and volume are strongly correlated with body height. This relation must be considered in clinical decisions on further investigations regarding kidney disease progression.

Abstract The relation between age and sex and the concentration of bilirubin in serum was evaluated in 6740 men and 11 215 women, ages 13 to 96 years. Mean serum bilirubin concentrations in the men significantly exceeded values in the women over all age groups examined. Further, mean serum bilirubin concentrations were greatest both in males and females in the 19-24 years age group and then declined to former values, which persisted throughout life. Pearson correlation coefficients for bilirubin with liver function indices (albumin and total protein) and with hemoglobin were low in all ages and in both sexes, suggesting that bilirubin concentrations do not correlate with those liver functions not directly concerned with bile pigment processing.

Age And Sex

The extent of mammalian movements often varies with size, sex and/or reproductive status. Fyke nets were set along streams and rivers near Melbourne (southern Victoria) from the mid-1990s to 2007, and in the Wimmera River catchment (western Victoria) from 1997 to 2005, to assess how far platypus of different age and sex classes travelled between captures and over longer periods. The mean distance between consecutive captures of adults did not vary significantly as intervals increased from 1–3 months to >3 years, suggesting that most individuals occupied stable ranges. However, adult females travelled, on average, only 35% as far between captures as males in southern Victoria, and 29% as far in the Wimmera. Up to half of this difference may be explained by variation in size-related metabolic requirements. Immature males and females respectively moved 61% and 53% as far, on average, as their adult equivalents, although two young males dispersed >40 km. Adults incrementally occupied up to 13.9 km of channel in the case of a male (based on six captures over 67 months) and 4.4 km of channel in the case of a female (based on five captures over 127 months).

AbstractA radiographic planimetric study of mastoid air cell system was carried out on 100 normal human subjects of which 50 were males and 50 females–who were further subdivided into five age groups. They had no history of past ear disease or any other clinical ENT abnormality. The mean area of the mastoid air cell system was measured planimetrically on X-rays and the data analysed according to age and sex. It was 12.05±0.67 cm2 in males and 11.45±0.70 cm2 in females (which are more or less the same as that of Western people).The size of the cranial bones has no apparent role in the size variation of the mastoid air cell system. The development of the latter was very rapid up to 10 years of age in both sexes and it continued even after 20 years of age but at a much slower rate.

Background: The study describes the retrospective analysis of 54 cases of facial nerve palsy patients seen in our neurophysiology Laboratory during February 2016 to January 2018.Methods: Clinically diagnosed cases of facial nerve palsy encountered at neurophysiology laboratory were analyzed on the basis of their diagnosis, age, sex, side affected and their seasonal occurrence. Patients were grouped in to four age groups of <20 yr, 21-40 yr, 41-60 yr and >60 yr.Results: Out of total 54 facial palsy cases with the mean age of 34.39±14.25 yr, 29 (53.70%) were males and 25 (46.30%) were females. Facial palsy was most common in 21-40 yr age group (42.59%, n=23), followed by 41-60 yr age group (29.63%, n=16). Nearly equal number of cases of right sided (26; 48.15%) and left sided (28; 51.85%) facial palsy were observe. However, right side facial palsy was more common in males with right side to left side facial palsy ratio of 1.90:1 and left sided facial palsy was more common in females with right side to left side facial palsy ratio of 1:2.57.Conclusions: Facial palsy cases are uniformly distributed among males and females with preponderance of right facial palsy in males and left facial palsy in females.

Our aim was to find out the association between nasal smear eosinophil count and allergic rhinitis (AR) and to determine a cutoff value that is significant for a diagnosis of AR. We also wanted to determine whether this count is related to the predominant symptoms, duration, or type and severity of AR, or to the presence of coexisting asthma. We selected 100 patients with a clinical diagnosis of allergic rhinitis across all age groups and an equal number of age- and sex-matched controls for the study. Their nasal smear eosinophil counts were recorded in terms of the number of eosinophils per high-power field (HPF). All patients were then clinically assessed for asthma and underwent spirometry. The data were recorded and appropriate statistical analysis done. The difference in the mean eosinophil counts of patients with AR and controls was found to be statistically significant (p = 0.000). A nasal smear eosinophil count of >0.3 per HPF had a 100% specificity and a 100% positive predictive value for AR. Asthma was associated with allergic rhinitis in 40% of patients; an association was not found between nasal smear eosinophil count and the symptoms, duration, type, and severity of allergic rhinitis or coexistent asthma. We conclude that an eosinophil count of >0.3 per HPF in nasal smears is a highly specific criterion for the diagnosis of AR. However, nasal smear eosinophil counts are poor indicators of the degree, duration, or type of upper or associated lower airway inflammation due to allergy.
