The Impact

The study was conducted to determine the impact of seasons, host size and sexes on the incidence of helminth community infecting Channa striatus (Bloch, 1793) from Punarbhaba and Atrai rivers of Dinajpur district. Four helminths were identified: one Cestoda, Bothriocephalus cuspidatus (Cooper, 1917); two Nematoda, Ascaridia spp. (Dujardin, 1845) and Camallanus intestinalus (Bashirullah, 1974); one Acanthocephala, Pallisentis ophiocephali (Thapar, 1930). Out of 75 hosts examined 52 were infected by 326 helminth parasites. Nematoda was the most dominant group (48.0%), followed by Acanthocephala (46.67%) and Cestoda (8.0%). The larger hosts were more infected than the smaller ones. A significant positive correlation was observed between the length of the host with respect to the abundance and prevalence of parasite for C. intentinalus and P. ophiocephali. Regarding the effect of seasonal changes, the prevalence of B. cuspidatus (14.81%) and Ascaridia spp. (22.22%) was highest in the rainy season. The highest prevalence of C. intestinalus (73.91%) was observed in winter. The prevalence of P. ophiocephali was high (84.0%) in summer. Except the abundance of B. cuspidatus (p = 0.147) all parasite species, Ascaridia spp. (p = 0.003), C. intestinalus (p < 0.01) and P. ophiocephali (p < 0.01) varied significantly among seasons. Overall prevalence of infection of male and female were 53.8% and 77.6%, respectively. A significant difference in the abundance of the parasite species with respect to host sex was observed only in C. intestinalus (Z = –2.886, p = 0.004).Dhaka Univ. J. Biol. Sci. 25(1): 39-46, 2016

The Impact

SUMMARYSampling of the fish community was carried out for 20 years in the Mirgenbach reservoir, in North-Eastern France. The prevalence and the mean intensity of Ligula intestinalis (Cestoda) were analysed in roach (Rutilus rutilus) and silver bream (Blicca bjoerkna) populations, the main two infected species. The aim of this study was to investigate the host switch from roach to silver bream and the consequences of L. intestinalis infestation in silver bream, which is an unusual host for this parasite as Ligula parasitism in silver bream appears to be rare. We analysed in detail the relationships between parasitism index (PI), gonadosomatic index (GSI), perivisceral fat abundance (PFA) and condition index (CI) in the silver bream population. In 1998, prevalence of L. intestinalis highlighted a clear host switch from roach to silver bream. In the silver bream population, young fish were the most severely infected and the impact of plerocercoids appeared to be different depending on the host sex. In male silver bream, plerocercoids drew energy from fat reserves even if GSI was also slightly impacted. On the contrary, in females energy was diverted from gonad maturation rather than from perivisceral fat reserves. No significant difference was observed in terms of CI in either sex.

AbstractSpiny mice,Acomys cahirinus dimidiatus, inhabiting the wadis close to St Katherine in the mountains of the Sinai peninsula, were trapped and their helminth parasites were studied. Sixty one mice provided faeces for analysis and 27 were killed and autopsied. Six species of helminths were recorded (the spirurid nematodes,Protospirura muricola(74.1%) andMastophorus muris(11.1%), the oxyuroid nematodes,Dentostomella kuntzi(59.3%),Aspiculuris africana(3.7%), andSyphacia minuta(3.7%) and the hymenolepidid cestodeRodentolepis negevi(18.5%)). The spirurids were the dominant species present, accounting for up to 0.87% of total host body weight. Analysis of worm weights and lengths suggested that transmission had been taking place in the months preceding our study. No sex difference in the prevalence or abundance of spirurids was detected. Significant differences were identified in the abundance of total nematode burdens and the mean helminth species richness between the three wadis which provided multiple captures of mice. There was also a marked effect of host age on both parameters. A highly significant positive correlation between spirurid egg counts and total worm biomass indicated that non-invasive techniques based on egg counts could be used to quantify worm burdens and when this technique was applied to a larger sample size (n= 61), a significant difference between sites but no host sex or age effects were detected for spirurid faecal egg counts. The data suggest that there are differences between helminth component communities infecting spiny mice in different neighbouring wadis, a hypothesis which will be explored further through our continuing studies in the Sinai.

Clinostomum Complanatum

A survey of helminth parasites of 40 belted kingfishers obtained from southern Québec during 1982 and 1983 yielded 11 species of which Uvulifer ambloplitis and Crassiphiala bulboglossa were the most common. The birds had an average of 2.8 species each and 6 parasite species were found to be aggregated in the host population. Three parasites recovered were previously unrecorded from this host: Clinostomum complanatum, Capillaria sp., and Strongyloides sp. Comparison of parasite burdens between male and female hosts and between years revealed no significant differences.

AbstractThe present study focuses on the helminth parasite community of the wild rabbit in a sand dune area in Portugal over a 5-year period. The influence of host sex and year on the composition of the helminth community is assessed, along with the potential effect of the detected helminths on host body condition. The basic structure of the helminth community comprisesMosgovoyia ctenoides,Graphidium strigosum,Trichostrongylus retortaeformis,Nematodiroides zembraeandPassalurus ambiguus. Mean intensities ofG. strigosumvaried between years. GeneralG. strigosumintensities were also found to vary according to both year and host sex, but not according to the interaction of both factors. When assessing the effect of helminths on rabbit body condition (expressed by the kidney fat index), higher burdens ofM. ctenoides, a cestode that presents a relatively large body mass, were found to induce a reduction in rabbit condition.

Female Subjects

To examine the impact of androgyny and attributional style on coping ability, a demographic questionnaire, the Zeitlin Coping Inventory, the Bem Sex-role Inventory and the Attributional Style Questionnaire were completed by 301 first-year students at the University of Stellenbosch. It was found that androgynous female subjects displayed significantly better coping abilities than female subjects with feminine, masculine, or undifferentiated sex-role orientations. No significant difference was found between coping abilities of androgynous and masculine male subjects, although both androgynous and masculine males showed significantly better coping abilities than males with feminine or undifferentiated sex-role orientations. Regarding a specific aspect of coping, namely flexibility of coping style, both male and female subjects with androgynous sex-role orientations displayed significantly more flexibility in their coping styles than subjects of any other sex-role type. Regarding attributional style, a significant positive correlation was found between good coping ability and an internal, stable, and global attributional style for positive events. A significant positive correlation was likewise found between good coping ability and an external, unstable, and specific attributional style for negative events. The conclusion was drawn that androgyny and an adaptive attributional style served as important coping resources.

Stimulating Hormone

Newborn screening for congenital hypothyroidism (CH) is performed by measuring the concentration of thyroxine (T4) and/or thyroid-stimulating hormone (TSH) in dried blood spots. Unfortunately, the levels of T4 and TSH vary due to multiple factors, and therefore the false-positive rate for the test is a challenge. We analyzed screening data from 2008 to 2017 to determine the effect of seasonal changes and manufacturer kit lot changes on T4 and TSH values and on numbers of infants referred. Over a 10-year period, we screened 2.4 million infants using commercially available fluoroimmunoassays to measure T4 and TSH concentrations in dried blood spots. During colder months, daily mean T4 and TSH values were higher and referral rates and false-positive rates were higher. However, there was no significant difference between the number of confirmed CH cases. Furthermore, in rare instances, we observed differences in T4 daily mean values during the 10-year period when manufacturer kit lot changes were made. Seasonal temperature variations influence measured T4 and TSH values and consequently lower the positive predictive value for CH testing in colder months. Newborn screening (NBS) programs should be aware that manufacturer kit lot changes may also influence T4 values.

The Impact

Stress in caregivers may affect the healthcare recipients receive. We examined the impact of stress experienced by 45 adult caregivers of their elderly demented parents. The participants completed a 32-item questionnaire about the impact of experienced stress. The questionnaire also asked about interventions that might help to reduce the impact of stress. After exploratory factor analysis, we reduced the 32-item questionnaire to 13 items. Results indicated that caregivers experienced stress, anxiety, and sadness. Also, emotional, but not financial or professional, well-being was significantly impacted. There was no significant difference between the impact of caregiver stress on members from the sandwich generation and those from the nonsandwich generation. Meeting with a social worker for resource availability was identified most frequently as a potentially helpful intervention for coping with the impact of stress.

This exploratory study examined the impact of implicit and explicit oral corrective feedback (CF) on the development of implicit and explicit knowledge of Japanese locative particles (activity de, movement ni and location ni) for those who directly received CF and those who observed CF in the classroom. Thirty-six college students in a beginning Japanese language course received either recast (implicit), metalinguistic (explicit) or no feedback during an information-gap picture description activity, and completed a timed picture description test (implicit knowledge) and an untimed grammaticality judgement test (explicit knowledge) in a pre-test, immediate post-test and delayed post-test. The results showed that overall there was no significant difference between CF types, and that CF benefited direct and indirect recipients similarly. Potential factors that might influence the effectiveness of CF, such as instructional settings, complexity of target structures and pedagogy styles, are discussed.

The Impact

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Quality of work life is the major factor to be considered in working environment of any organization. The performance of employees and the organization lies on the ability of the employees based on working environment. The QWL leads to better working environment which improves the performance of organization. The present study has made an attempt to find the level of factors causing QWL and the impact of outcome of QWL in banks. Since the profile of the banks may be associated with the level of outcomes of QWL, the present study has made an attempt to examine it with the help of one way analysis of variance and t-test. The included outcomes of QWL are job satisfaction, job stress, organizational climate, organizational commitment, employees retention behaviour, service quality employees and service productivity of employees. The highly associated determinants of QWL and the significant difference among the PUSBs and PRSBs have been noticed. The significantly associating important profiles of the banks regarding the existence of outcome of QWL are identified.
