It is generally believed that hepatitis B (HBV) and C (HCV) viruses are highly prevalent in the Republic of Yemen. This study investigated the prevalence of HBV and HCV markers in 494 blood donors from Aden, 493 blood donors from Sana'a, 97 residents from an African ethnic minority in Sana'a and 99 residents of Soqotra Island. There were significant differences in the prevalence of HBV carriage (HBsAg: 6·7, 15, 19·6 and 26·3% respectively; P<0·001); past HBV infection (anti-HBc: 17·4, 18·5, 30·9 and 59·6% respectively; P<0·001); susceptibility to HBV (absence of HBV markers: 73·3, 61·9, 38·1 and 9·1% respectively; P<0·001), infectivity of HBV carriers (HBV DNA: 51·5, 33·8, 52·6 and 65·4% respectively; P=0·028) and HCV antibodies (RIBA confirmed or indeterminate: 0·6, 0·2, 5·2 and 5·1% respectively; P<0·001). A significant difference in HBV carrier rate and a borderline significant difference in the prevalence of natural infection was observed between males and females in the African community (P=0·02 and 0·06 respectively). In contrast, in Soqotra Island, there was no significant sex difference in HBV carrier rate but susceptibility was significantly more prevalent in males (P=0·03). This study illustrates that significant difference in prevalence and epidemiology exists among different communities within the same country, reflecting political, geographical and social differences. Control strategies should take these differences into account.

The studies were performed in the period 2008-2015 in orchards from the central part of the Republic of Moldova and Bacău County, Romania. In both areas 12 species rodent were registered, of which in central Moldova orchards the species R. norvegicus and P. subterraneus were not registered, while in Bacau orchards the species A. uralensis, M. rossiaemeridionalis and D. nitedula weren’t recorded. In CM orchards the dominant species was M. rossiaemeridionalis with about 30%, followed by A. sylvaticus and A. flavicollis. In BC orchards the dominant species was A. flavicollis with more that 41%, followed by A. sylvaticus and M. arvalis.The analysis of demographic structure in spring period showed a high proportion of reproductive females in all species, being the highest at M. rossiaemeridionalis in CM orchard and in A. flavicollis in BC orchard. The share of young individuals constituted up to 40% depending on the species being the highest at M. rossiaemeridionalis in CM orchard and in A. flavicollis in BC orchard. A significant difference in the area of the individual sectors of M.rossiaemeridionalis males and females in the orchard in summer (t = 3.46) and autumn (t = 3.39) was established, as well as for A. sylvaticus in the spring and summer period (t = 2.06; 2.03), and for A.uralensis in spring and autumn (t = 2.99; 3.44).

F.VIII R:Ag was determined by quantitative immunelectrophoresis (I.E.) with a prefabricated system. The prefabricated system consists of a monospecific f.VIII rabbit antiserum in agarose on a plastic plate for the one and two dimensional immunelectrophoresis. The lognormal distribution of the f.VIII R:Ag concentration in the normal population was confirmed (for n=70 the f.VIII R:Ag in % of normal is = 95.4 ± 31.9). Among the normal population there was no significant difference between blood donors (one blood donation in 8 weeks; for n=43 the f.VIII R:Ag in % of normal is = 95.9 ± 34.0) and non blood donors (n=27;f.VIII R:Ag = 94.6 ± 28.4 %). The f.VIII R:Ag concentration in acute hepatitis B ranged from normal to raised values (for n=10, a factor of 1.8 times of normal was found) and was normal again after health recovery (n=10, the factor was 1.0). in chronic hepatitis the f.VIII R:Ag concentration was raised in the majority of the cases (for n=10, the factor was 3.8). Out of 22 carrier sera 20 showed reduced, 2 elevated levels of the f.VIII R:Ag concentration. in 5 sera no f.VIII R:Ag could be demonstrated. The f.VIII R:Ag concentration was normal for n=10, reduced for n=20 and elevated for n=6 in non A-non B hepatitis (n=36). Contrary to results found in the literature no difference in the electrophoretic mobility of the f.VIII R:Ag was found between hepatitis patients sera and normal sera.

Abstract Background Psychological disorders are common among individuals who experienced COVID-19. Previous studies have shown that females report higher depression and anxiety than males. The present study aims to test the differences in depression and anxiety between males and females who have experienced COVID-19. This a descriptive, observational, comparative study, among Saudi Arabian population. A total of 686 participants have been recruited. Participants completed an online questionnaire that contains questions about sociodemographic, COVID-19, Generalized Anxiety Disorder (GAD-7) questionnaire, and Patient Health Questionnaire (PHQ-9) to measure anxiety and depression, respectively. Results Twenty-six percent of the participants were excluded and our final sample consisted of 507 participants (median age 23; 65% females). Of the final sample, 23% (118) have been previously diagnosed with COVID-19. There is no significant difference in GAD-7 and PHQ-9 scores between COVID-19- positive and COVID-19-negative populations. However, females who have experienced COVID-19 reported significantly higher GAD-7 and PHQ-9 scores compared to males. Conclusion The results of our study show that females are significantly at a higher risk for depression and anxiety as a result of COVID-19 infection compared to males. Further epidemiological studies are required for a better understanding of this correlation.

Bedtime Procrastination

Abstract Introduction Bedtime Procrastination (BP) is defined as the behavior of voluntarily delaying going to bed, without having external reasons for doing so. Recent research on procrastination behavior suggests that when negative emotions are elevated, procrastination behaviors can be triggered in order to find pleasure to avoid and alleviate them. Procrastination can also occur when there is difficulty regulating emotions. In addition, the reason for bedtime procrastination may be different depending on whether the individuals present with insomnia. According to previous studies, patients with insomnia may exhibit more pronounced negative avoidance of bedtime due to prolonged sleeplessness. Therefore, this study compared the difference between of the bedtime procrastination and the emotional regulation strategies between the insomnia group and the healthy group. Methods This study was conducted in 582 adults (mean age 23.06 ±2.16 years), 81.6% females. Individuals scoring higher than 15 on the Insomnia Severity Index (ISI) were classified into the insomnia group (n=375), and those less than 15 were classified into the healthy group (n=207). Participants completed the Bedtime Procrastination Scale (BPS), Emotional Regulation Strategies Checklist. Data was analyzed using descriptive statistics, chi square test, and independent t tests. Results The insomnia group had significantly higher bedtime procrastination scores than the healthy group (t=-6.241, p&lt;.001), and also the avoidant/distractive regulation style score was significantly higher (t=-1.969, p&lt;.05). In addition, the score of active regulation style was significantly lower in the insomnia group than in the healthy group (t=3.050, p&lt;.01). There was no significant difference between the two groups in the support-seeking regulation style. Conclusion Based on these results, it was confirmed that there was a difference in the bedtime procrastination and the emotional regulation strategies between the insomnia group and the healthy group.

This study aimed to examine inter-limb jump asymmetries and their association with sport-specific performance in young swimmers. Thirty-eight (male, n = 19; female, n = 19) regional/national level young swimmers (age: 12.3 ± 1.2 years; height: 159.6 ± 8.2 cm; body mass: 52.5 ± 9.2 kg) participated in this study. Inter-limb asymmetries were assessed for single-leg countermovement jump (SLCMJ) and single-leg standing long jump (SLSLJ). Sport-specific performance was evaluated using front crawl (i.e., 50 m and 25 m) and front crawl kick (i.e., 50 m and 25 m). The kappa coefficient revealed a “slight” level of agreement (Κ = 0.156, 0.184, and 0.197 for female, male, and all, respectively) between the direction of asymmetry for SLCMJ and SLSLJ, indicating that asymmetries rarely favored the same limb during both tests. A paired sample t-test showed a significant difference (p = 0.025) between asymmetry scores obtained in SLCMJ and SLSLJ. No significant difference was found in asymmetry scores between males and females (p = 0.099 to 0.977). Additionally, no association between asymmetry scores and sport-specific performance was observed (p > 0.05). Our findings highlight the independent nature of inter-limb asymmetries derived from SLCMJ and SLSLJ among young male and female swimmers. Further, our results suggest no association between jumping asymmetries and sport-specific performance.

Smartphone has become an essential part of human lives. People tend to treat it as another part of their body. Besides communication purposes, it is used for searching information, monetary transactions, shopping, social networking, entertainment, etc. This study aims at analysing the factors influencing smartphone usage and behavioural changes among college students under four constructs: utilisation, benefits, nomophobic behaviour and perceived risks (UBNR). An instrument was created with factors concerning the research and administered in a top-ranked private university of Bangalore, India. The research was carried out with a total of 122 responses. The results show that there is no significant difference in the attitude of males and females in most of the factors except social anxiety. Females experience more social anxiety and use smartphone more for maintaining their social relationships. There is no significant difference between the age group of students in all the four constructs. Utilisation is positively related with psychological, social, functional and financial benefits and shows that the greater the usage of smartphone, the greater are the benefits. On the other hand, the study reveals that increased usage of smartphone leads to addiction, causes nomophobia and poses threat of perceived risks. A mediation strategy like educating the students for proper use of technology is necessary to overcome the risk of addiction and developing nomophobia.

The aim of the study is to determine the role of geochemical factors (the content of Mg, K, Ca, Zn, Pb in soils and natural waters of the plain zone of Dagestan) in the prevalence of essential arterial hypertension (EAH) among the population of children. Materials and methods of research: an observational cross-sectional (one-step) study of the prevalence of EAH in the child population was carried out. The prevalence rates of EAH among children in the plain zone of the Republic of Dagestan are calculated for 100,000 children 0–17 years old, without taking into account gender differences. The content of elements (Mg, K, Ca, Zn, Pb) in the environment (soil, natural waters) was determined by atomic absorption spectroscopy. Results: one-way analysis of variance (One-Way ANOVA) of indicators of the content of metals (Mg, K, Ca, Zn, Pb) in the regions and objects (soils, natural waters) of the study revealed a statistically significant difference in the data (for soils: F=81,06772, p<0,0002; for natural waters: F=58,86451, p<0,00001). The dependence of children's EAH on the content of chemical elements in the objects of the biosphere of Dagestan was determined, which was expressed in an increase in the number of patients with EAH when Pb content exceeded (r=+ 0,576, r=+ 0,759) and with the decrease of Mg (r=–0,668, r=–0,173), K (r=–0,440, r=–0,636), Ca (r=–0,693, r=–0,533), Zn (r=–0,051, r=–0,827) in soils and natural waters. Conclusion: when assessing the pathogenesis of EAH in the population of children, the content of Mg, K, Ca, Zn, Pb in soil and water should be taken into account, since these microelements, entering the body with water and food, affect the elemental status of child's body.

The blood profile and histology of selected tissues (kidney, lungs, intestine, and epididymis) of Balami Sheep fed Shea Cake meal supplement was investigated. A total of thirty-two (32) sheep of the average weight range of 11.75-14.75kg comprising an equal number (16) of males and females were randomly allotted to four dietary treatments in a completely randomized experimental design with eight sheep per treatment for twelve weeks duration. Treatment 1 (T1) was a control diet and had zero inclusion level of Shea cake meal (SCM), while treatments 2,3, and 4 had 10%,15%, and 20%  inclusion of SCM, respectively. At the twelfth week of the experiment, two blood samples of 5ml each were taken from each animal from the jugular vein. The first set was preserved in Ethylene Diamine Tetra Acetic Acid (EDTA) bottle for haematological parameters, while the second samples were preserved without EDTA for serum examination. Representative samples of tissues were randomly selected and slaughtered for gross microscopic examination. There was a significant difference (P<0.05) at various levels of inclusion for parameters investigated. The white blood cell (WBC), Red blood cell (RBC), and Packed cell volume (PCV) recorded the highest values at T3 (15% inclusion level) (13.42 x109/L), 2.92x1012/L, 3.75%, respectively). The serum parameters were significantly(p <0.05)different among the treatments. Total protein ranges from 54.78(mg/dl) (T1) - 60.51(mg/dl) (T2), Cholesterol70.15(mg/dl) (T1) - 78.00(mg/dl) (T4). Iron ranges from 58.15(ug/dl) (T1) - 62.88(ug/dl) (T3).The histopathology of tissues (kidney, lungs, intestine, and epididymis) showed no alteration across the treatments (P= .05) in the gross microscopic examinations. No lesion was observed in the lungs, kidney, epididymis, and intestine. The results showed that shea cake meal posed no health risk to Balami sheep and as such recommended as a good supplement in the diets of the sheep.

Background: The spheno‐occipital synchondrosis (SOS) is an important growth center which plays an important role in cranial base development and can define the final relation of SOS with the upper and lower jaws. The morphology and fusion degree of SOS varies in different ages among different populations. Objectives: Thus, the aim of this study was to evaluate the age and sex dependence of ossification of the spheno-occipital synchondrosis in the Iranian population using CBCT. Methods: This cross-sectional retrospective study was performed on 517 CBCT images of 6- to 18-year-old patients in Mashhad, Iran. Patients with obvious pathology or fractures were excluded from the study. The SOS ossification was classified into four stages from 0 to 3. Two independent observers scored the images. The ossification stage of the SOS was classified according to the age and sex of the patients. Kruskal-Wallis and Kendall’s tau-b used for statistical analysis. Results: In this study, 517 samples of 260 females (50.3%) and 257 males (49.7%) with a mean age of 12.03 ± 3.74 years were examined. A significant difference did not exist between males and females regarding their stage of SOS ossification, although males were younger at the SOS transitional stages of 0 to 1, and 1 to 2 compared to females. Also, the SOS starts the ossification process at the age of 11 in females and 10.8 in males. Conclusions: The present study showed in the mean age of 16.81 ± 1.12 years, most subjects were in developmental stage 3. Due to the fact that in developmental stage 3 SOS closes, there were no passive maxillary growth after this time. In none of the SOS stages, females and males differed significantly in mean age (P > 0.05). The age of the onset of SOS closure in females was 11 years and in males it was about 10.8 years.
