The trachea forms the part of the conducting system which transports air from the external environment to the lungs. The aim of this study was to provide quantitative dimensions of the trachea of Red Sokoto goat (Capra hircus). Quantitative analysis was conducted on nine tracheas from goats (ages were ranged between eight months and three years) without sex variation in this study. The results showed that tracheas were extended from the cricoid cartilage of larynx to the hilus of the lungs, where they were divided into the right and left bronchi. They were structurally composed of the cartilaginous rings that were incomplete dorsally but bridged by tracheal muscles at the ends of the tracheal cartilages. The mean length of the trachea from the first to the last ring was 257 ± 7.11 mm and the number of tracheal rings varied from 35 to 57, with a mean value of 49.33 ± 2.78. The left bronchial mean length (19.78 ± 2.66 mm) was significantly longer than the right (10.44 ± 1.79 mm). The cross-sectional area (CSA) was wider at the intrathoracic area (221.5 ± 0.2 mm2) than cervical area (176 ± 0.1 mm2).

Abstract Background This study aims at determining the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability. Methods Two critical-size defects (CSDs) were bilaterally trephined in the parietal bone of 36 adult Sprague-Dawley rats (18 males and 18 females); the left remained empty (group A), while the right CSD was filled with nHAp/CS scaffold (group B). Two female rats died postoperatively. Twelve, 11, and 11 rats were euthanized at 2, 4, and 8 weeks post-surgery, respectively. Subsequently, 34 specimens were resected containing both CSDs. Histological and histomorphometric analyses were performed to determine the FBR, calculated as [the sum of areas of newly formed bone in lateral and central regions of interest (ROIs)]/area of the original defect, as well as the Ost and the CD (Ost/mm2) in each ROI of both groups (A and B). Moreover, biodegradability of the nHAp/CS scaffolds was estimated via the surface area of the biomaterial (BmA) in the 2nd, 4th, and 8th week post-surgery. Results The FBR of group B increased significantly from 2nd to 8th week compared to group A (P = 0.009). Both the mean CD and the mean Ost values of group B increased compared to group A (P = 0.004 and P < 0.05 respectively). Moreover, the mean value of BmA decreased from 2nd to 8th week (P = 0.001). Conclusions Based on histological and histomorphometric results, we support that 75/25 w/w nHAp/CS scaffolds provide an effective space for new bone formation.

AbstractThe levels of acrylamide intake because of potato crisps consumption remains unknown in Kenyan context. This study assessed the exposure to acrylamide because of consumption of potato crisps in Nairobi, Kenya. A cross-sectional survey was carried out among 315 crisps consumers in Nairobi, and consumption patterns were collected using a pre-tested structured 7-day recall questionnaire. A total of 43 branded and 15 unbranded potato crisps samples were purchased in triplicates of 100 g and acrylamide was quantified using a gas chromatograph with a flame ionization detector. Consumption data were combined with the data on acrylamide contents from which dietary acrylamide intake was calculated using a probabilistic approach based on @Risk TopRank 6 risk analysis software for excel. The mean estimated acrylamide intake was 1.57 µg/kg body weight (BW) per day while the 95th (P95) percentile was 5.1 µg/kg BW per day, with margins of exposures (MOE) being 197 and 61, respectively. The intake of acrylamide was significantly (P < 0.05) higher in unbranded crisps with a mean value of 2.26 and 95th percentile of 6.54 µg/kg BW per day, MOE being 137 and 47, respectively. There were extremely lower MOE indicating higher exposure to acrylamide by the consumers mainly because of the higher acrylamide contents in potato crisps, and hence the need for mitigation measures.

Objective: To evaluate the frequency of use of oral contraceptives and other risk factors among women with ischemic stroke seen at a hospital in the northern region of the state of Rio Grande do Sul. Methods: Prospective, cross-sectional study. The population was characterized by patients admitted with a diagnosis of ischemic stroke during a period from March to August 2019 and the sample by female patients found in the population. The data were collected through an individual interview using a questionnaire developed by the researchers and tabulated for further analysis. All analyzes were performed using the statistical program Bioestat 5.0, considering p = 0.05. Results: In the characterization of the sample, an average age of 68.2 years was observed. The occurrence of gender was 52.4% for women. The mean hospital stay was 12.2 ± 8.91 days. Outcome of hospital discharge was 89.1%. The mean value of body mass index was 25 ± 4.89 kg / m², with an average of 27.4 kg / m² in patients who used oral contraceptives and 25.23 kg / m² in patients who did not use oral contraceptives. The sample had a 34.5%incidence of oral contraceptive use. The average age of those who used oral contraceptives was 62.4 years and of the patients who did not use it was 70.3 years. Conclusion: The study showed a high use of oral contraceptives in the sample, with percentage values very close to other factors evaluated, thus showing itself as a probable risk factor for the development of ischemic stroke.

Le seuil de significativité était retenu pour p<0,05. Résultats: Deux cent cinquante et un patients avaient été inclus. L’hémorragie était d’origine hypertensive portale chez 69 patients (27,71%) ; ulcéreuse gastro-duodénale chez 100 patients (39,84%). Chez 25 patients (9,96%), la fibroscopie oesogastroduodénale était normale. Une rupture de varices oesophagiennes était retrouvée chez 98,55% des patients présentant une hypertension portale. Les ulcères gastroduodénaux représentaient 54,94% des hémorragies digestives hautes d’origine non hypertensive portale. La valeur moyenne du score de Rockall était de 4(±1) chez les patients présentant une hémorragie d’origine hypertensive et de 3(±1) chez les patients avec hémorragie non hypertensive portale (p<0,001). La valeur moyenne du score de Glasgow-Blatchford était de 10(±3) chez les patients présentant une hémorragie d’origine hypertensive et 9(±3) chez les patients avec hémorragie digestive haute d’origine non hypertensive (p<0,001). La récidive hémorragique et le décès étaient survenus chez les patients présentant un saignement d’origine hypertensive portale dans respectivement 54,84% (p<0,001) et 71,42% (p<0,001). Conclusion: Les lésions inflammatoires aiguës et chroniques représentent la première étiologie des hémorragies digestives hautes dans le service d’Hépato-gastroentérologie du CHU Campus. Ces hémorragies sont associées à la prise de médicaments gastrotoxiques et à un moindre risque de récidive hémorragique et de décès. Objective: To describe epidemiological et prognostic outcomes associated with etiologies upper gastrointestinal bleeding in Campus Teaching Hospital of Lome Patients and method: Cross-sectional study with retrospective collection, descriptive and analytical aim carried out from January 1, 2014 to December 31, 2019. Results: Two hundred and one patients were included. The hemorrhage was of portal hypertensive origin in 69 patients (27.71%); peptic ulcer in 100 patients (39.84%). In 25 patients (9.96%), the oesogastroduodenal fibroscopy was normal. Ruptured esophageal varices were found in 98.55% of patients with portal hypertension. Peptic ulcers accounted for 54.94% of upper GI bleeding of non-portal hypertensive origin. The mean value of the Rockall score was 4(±1) in patients with hemorrhage of hypertensive origin and 3(±1) in patients with non-portal hypertensive hemorrhage (p<0.001). The mean Glasgow-Blatchford score was 10(±3) in patients with hemorrhage of hypertensive origin and 9(±3) in patients with upper GI hemorrhage of nonhypertensive origin (p<0.001). Hemorrhagic recurrence and death occurred in patients with bleeding of hypertensive origin in 54.84% (p<0.001) and 71.42% (p<0.001) respectively. Conclusion: Acute and chronic inflammatory lesions represent the first etiology of upper GI bleeding in the Gastroenterology Department of the Campus Teaching Hospital of Lome. These hemorrhages are associated with the use of gastrotoxic drugs and with a lower risk of recurrence of hemorrhage and death.

Abstract Background: HAART has been reported to be associated with a number of side effects in human immunodeficiency virus patients among which dyslipidemia is a common metabolic disorder. Methods: A facility based comparative cross-sectional study among 228 HIV positive persons was conducted from July to August 2020. Socio-demographic and clinical data were collected using structured questionnaires. Fasting venous blood sample was drawn for Lipid profiles and CD4 cell determination. Anthropometric measurement was done. Data was analyzed using SPSS version 22 for windows. Result: A total of 228 HIV patients were enrolled in the study. Prevalence of dyslipidemia in HAART naive and on HAART HIV positive persons was 61(53.5%) and 84 (73.7%), respectively. The prevalence of TC≥200 mg/dl was 50% and 30%; HLD-c<40 mg/dl was 43.8% and 36%; LDL-c≥130mg/dl was 48.3% and 28.1%; and TG≥150 mg/dl 59.6% and 39% among on HAART and HAART naïve, respectively. Age greater than 40 years (AOR = 3.27, 95% C.I: 1.47 - 7.25), blood pressure ≥ 140/90 (AOR = 16.13, 95% C.I: 5.81 - 44.75), being on HAART (AOR = 2.73, 95 % C.I: 1.35 - 5.53) and body mass index > 25kg/m2 (AOR = 1.92, 95 % C.I: 1.20 - 4.81) were identified as determinants of dyslipidemia. Conclusion: The mean value of lipid profile was significantly higher among HIV positive clients on HAART as compared to those HAART naïve HIV positive clients.

Objective: To assess factors associated with the average number of dental caries in pregnant women. Method: Basic research design: This cross-sectional study was performed between January 2017 and December 2018 in Santa Maria, Brazil. Clinical setting and participants: Multistage random sampling resulted in the recruitment of 256 pregnant women from public health centers across the city. Clinical exams and semi-structured questionnaires including demographic, socioeconomic and behavioral questions were performed by trained interviewers. Main outcome measure: The experience of dental caries was evaluated through the mean value of the Decay, Missing, and Filled Surface Index (DMFS) by 4 trained and calibrated examiners. Multilevel Poisson regression models were used to evaluate the influence of different variables on the average number of dental caries. Rate ratio (RR) and respective 95% confidence intervals were calculated (CI 95%). Results: The prevalence of untreated dental caries was 62.7% in the sample, while the mean DMFS index was 10.27 (± 10.92). Women who smoked during pregnancy had a higher mean DMFS (RR 1.41; 95% CI 1.25-1.57). Furthermore, pregnant women who had poor self-ratings of oral health had a higher average DMFS (RR 1.21; 95% CI 1.10-1.32). Conclusions: The results showed that older age, ethnicity, fewer years in education and the presence of dental plaque resulted in higher means of DMFS.

Quantitative aspects of the colonization of the gonads by germ cells in the quail embryo (Coturnix coturnix japonica) A quantitative analysis made on quail embryos coming from 13 isolated parent couples reveals some significative variations of a genetic origin, between some of the off spring studied: the differences observed concern both the quantitative importance of the colonization of gonads by germ cells and the asymmetrical distribution of PGCs (primordial germ cells) between the two genital ridges. The chronological study of the colonization in the quail shows, as in both the duck and the chick, two periods of rapid and regular increase of the number of gonadic PGC, at stages from 13 to 18 and from 24 to 30 of Hamburger & Hamilton. The distribution of germ cells between the two genital ridges is, at the beginning of the colonization, not very asymmetrical. Between stages 18 and 24 the asymmetry increases and remains stable so that the mean value of D % (percentage of the number of PGC contained in the right gonad) from that moment on is equal to 29–34 %. This value is specific for the quail embryo.

ObjectiveWe aim to describe the anatomy and symmetry patterns of the optic canal in patients having undergone maxillofacial CT imaging.MethodsIn this retrospective chart review, we included all patients who received sinus and maxillofacial CT at the University of North Carolina hospitals between 2008 and 2016, without facial or cranial fractures or other medical conditions that would affect optic canal size. We measured the length of ≥75% enclosed canal, minimum cross-sectional area and minimum diameter bilaterally using iNtuition TeraRecon (Durham, North Carolina) and compared bilateral symmetry using a 20 % difference threshold. Each parameter above was compared among white, black, non-white and non-black patients.ResultsOf 335 patients, the mean canal length was 5.61±2.22 mm. The mean minimum area was 11.84±3.11 mm2. The mean minimum diameter was 3.28±0.55 mm. A total of 39.4% (132/335) of patients had asymmetric canal lengths, 18.8% (63/335) had asymmetric minimum areas, and 12.5% (42/335) had asymmetric minimum diameters. No differences were found between racial groups. The right optic canal was larger than the left (right: 12.12 mm vs left: 11.55 mm, p<0.0001).ConclusionOptic canal asymmetry is not uncommon. It may affect risk of papilloedema severity, explain cases of unilateral or asymmetric papilloedema and possibly asymmetric glaucoma.

ObjectiveTo analyse the secular trends in mean value and distribution of weight, height and weight for height in children under 7 years in developed regions in China.DesignFive repeated cross-sectional surveys were conducted using the same methods at the same sites during 1975–2015.SettingNine cities in northern, central and southern regions of China.PopulationHealthy children under 7 years; the sample sizes were 94 496 in 1975, 79 177 in 1985, 79 152 in 1995, 69 760 in 2005 and 83 583 in 2015.Main outcome measuresWeight and height were measured by the same methods in the five surveys.ResultsThe increasing trends in the mean value of weight, height and weight for height were observed and their distribution was found to have shifted upwards. There were unbalanced increments in various centiles and the relative increments in the 3rd centile of height for children under 7 years were larger than those in the 50th and 97th centiles. Although the relative increments in the 3rd centile of weight for children under 2 years were larger than those in the 50th and 97th centiles, the increments in the 97th centile for children older than 2 years became the largest compared with other centiles. The changes in each centile of weight for height were similar with those of weight. The annual increments of height and weight increased over time and were more significant between birth and 2 years of age for height and between ages 4 years and 6 years for weight. The per-decade increments in 1975–1985, 1985–1995 and 1995–2005 became larger, while those in 2005–2015 slowed down.ConclusionsThe rapid increasing trends of weight, height and weight for height had slowed down since 2005 in developed regions of China. The relative increments in the low centile of height were more significant, while the high centile of weight and weight for height increased more significantly in older children.

Background: Controversies still prevail on glomerular changes of kidney whether due to normal aging or its association with diseases Objective: The aim of the present study was to see the variation in number and size of the glomeruli of kidney with increasing age in a Bangladeshi population based on autopsy. Methods: This cross-sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2008 to June 2009, based on collection of 140 post mortem human kidneys collected from 70 unclaimed dead bodies from the morgue. All the samples were divided into three age-groups: 10-19 years, 20-39 years and 40-59 years. Histological slides were prepared by using routine Harris’ Haematoxylin and Eosin (H & E) stain. The number of glomeruli was measured by point counting technique, while the size (diameter) was measured by using ocular and stage micrometer. Results: The mean ± SE number of glomeruli per sq. mm found in the right and left kidney were 8.45±0.52 and 8.67±0.80 in group 10-19 years, 9.90±0.42 and 9.92±0.47 in 20-39 years, and 8.52±0.18 and 8.55±0.16 in 40-59 years respectively. Besides, the size (mean ± SE diameter) of glomeruli was found in the right and left kidney were 43.96±3.01ìm and 143.92±2.90ìm in group 10-19 years, 153.69±5.18ìm and 153.61±5.24ìm in 20-39 years, and 140.48±0.95ìm and 140.78±0.88ìm in 40-59 years respectively. Conclusion: No difference was found in number and size of glomeruli between right and left kidney in any group. Similarly, no difference was also evident among different age groups.
