Recruitment of larval Atlantic menhaden (Brevoortia tyrannus) to North Carolina and New Jersey estuaries: evidence for larval transport northward along the east coast of the United States

Age, size, abundance, and birthdate distributions were compared for larval Atlantic menhaden (Brevoortia tyrannus) collected weekly during their estuarine recruitment seasons in 1989–90, 1990–91, and 1992–93 in lower estuaries near Beaufort, North Carolina, and Tuckerton, New Jersey, to determine the source of these larvae. Larval recruitment in New Jersey extended for 9 months beginning in October but was discontinuous and was punctuated by periods of no catch that were associated with low water temperatures. In North Carolina, recruitment was continuous for 5–6 months beginning in November. Total yearly larval density in North Carolina was higher (15–39×) than in New Jersey for each of the 3 years. Larvae collected in North Carolina generally grew faster than larvae collected in New Jersey and were, on average, older and larger. Birthdate distributions (back-calculated from sagittal otolith ages) overlapped between sites and included many larvae that were spawned in winter. Early spawned (through October) larvae caught in the New Jersey estuary were probably spawned off New Jersey. Larvae spawned later (November–April) and collected in the same estuary were probably from south of Cape Hatteras because only there are winter water temperatures warm enough (≥16°C) to allow spawning and larval development. The percentage contribution of these late-spawned larvae from south of Cape Hatteras were an important, but variable fraction (10% in 1992–93 to 87% in 1989–90) of the total number of larvae recruited to this New Jersey estuary. Thus, this study provides evidence that some B. tyrannus spawned south of Cape Hatteras may reach New Jersey estuarine nurseries

Representations of the postcolonial state in the childhood metaphor in selected postcolonial texts

In the analysis of postcolonial literature, there is no systematic construction of a framework to factor in childhood as a metaphor. Postcolonial criticism has not been engaged further in the enterprise of literary analysis, particularly on form. Consequently, this research fills the need to recast the focus of postcolonial criticism to the analysis of form in literature†(through the use of metaphor of childhood). Hawley picks out one author, Salman Rushdie who is often studied under postcolonial criticism. He singles out that postcolonial critics look only for Rushdie-like characteristics. It is in the interest of this research to apply childhood as a different set of characteristic or criterion to profit the agency of postcoloniality. This research also, therefore, contributes to this critique by establishing further that postcolonial criticism embodies a wider canon and that postcolonial texts are not a ‘handful and recurring’. This research introduces pericolonial zones as well as exposing further ‘the list’ to include the selected texts; Beneath the Lion’s Gaze, in addition to The God of Small Things and Nervous Conditions. A sifting of childhood metaphor, in relation to postcoloniality, engenders further appreciation on the analysis of the literary context and beyond

Experimental ionization of atomic hydrogen with few-cycle pulses

We present the first experimental data on strong-field ionization of atomic hydrogen by few-cycle laser pulses. We obtain quantitative agreement at the 10% level between the data and an {\it ab initio} simulation over a wide range of laser intensities and electron energies

Prevalence and predictors of health service use among Iraqi asylum seekers in the Netherlands

BACKGROUND. A long asylum procedure is associated with higher prevalence rates of psychiatric disorders, lower quality of life, higher disability and more physical health problems. Additional knowledge about health seeking behavior is necessary to guide governments and health professionals in their policies. OBJECTIVE. To measure service use among one of the biggest asylum seekers population in the Netherlands and to assess its relationships with predisposing and need variables (including post-migration living problems). METHOD. Two groups were randomly selected: Group 1 (n = 143), less than 6 months and Group 2 (n = 151), more than 2 years in the Netherlands. Respondents were interviewed with fully structured, culturally validated, translated questionnaires, which contained instruments to measure psychiatric disorders, quality of life, disability, physical health and post-migration living problems. Use of preventive and curative (physical and mental) health services was measured and the relationship with predisposing and need risk factors was estimated with univariate and multivariate logistic regression analyses. RESULTS. A long asylum procedure is not associated with higher service use, except for mental health service use and drug use. Use of mental health services is, however, low compared to the prevalence of psychiatric disorders. Low quality of perceived general health and functional disability are the most important predictors of services use. Psychopathology predicts use of a medical specialist (non-psychiatrist), but does not predict mental health service use. CONCLUSION. A high percentage of asylum seekers with a psychiatric disorder is not getting adequate treatment. There is a mismatch between the type of health problem and the type of health service use. The various health services should work together in education, detection, referral and care in order to provide help to this group of patients.De Open Ank

Comparison of self-reported health & healthcare utilisation between asylum seekers and refugees: an observational study

<p>Abstract</p> <p>Background</p> <p>Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context.</p> <p>Methods</p> <p>Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications.</p> <p>Results</p> <p>Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2–17.9) and depression/anxiety (OR 5.8, 95% CI: 2.2–15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3–12.7; OR 3.4, 95% CI: 1.2–10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1–11.9; OR 3.3, 95% CI: 1.0–10.4) or post migration stressors (OR 17.3, 95% CI: 4.9–60.8; OR 3.9, 95% CI: 1.2–12.3) were independent predictors of self reported PTSD or depression/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (χ²= 19.74, df = 1, P < 0.001).</p> <p>In terms of health care utilisation, asylum seekers use GP services more often than refugees, while no significant difference was found between these groups for use of dentists, medication, hospitalisation or mental health services.</p> <p>Conclusion</p> <p>Asylum seekers have a higher level of self reported PTSD and depression/anxiety symptoms compared to refugees. However, residence status appears to act as a marker for post migration stressors. Compared to refugees, asylum seekers utilise GP services more often, but not mental health services.</p

Age-related changes in T lymphocytes of patients with head and neck squamous cell carcinoma

Introduction The number of aging cancer patients has increased continuously and will do so further in the future. The immune system of elderly people experiences critical changes over the time. Therefore, tumor-induced changes in the immune system are believed to differ in young and elderly cancer patients as well. Methods The effect of aging on the immune system was measured in peripheral blood lymphocytes (PBL) of healthy volunteers (n = 48, 21–84 yrs.) divided into three different age groups. Seventy years was set as a cut-off for defining subjects as elderly. Results were compared to two groups of adult cancer patients, which donated PBL and tumor infiltrating lymphocytes (TIL): young cancer patients (40–69 yrs.; blood: n = 13; TIL: n = 17) and elderly cancer patients (70–90 yrs.; blood: n = 20; TIL: n = 15) with head and neck squamous cell carcinoma (HNSCC). Frequencies and phenotypes of CD4+ and CD8+ T cells as well as regulatory T cells (Treg) were assessed by flow cytometry. Results We observed lower frequencies of CD8+ cytotoxic T cells during aging in both groups. Frequencies of tumor infiltrating regulatory T cells were significantly higher than in the peripheral blood but showed a significant decline in older tumor patients. With increasing age, expression of immunosuppressive CD73 and CCR7 was lower and expression of PD1 elevated on peripheral T cells in healthy volunteers and tumor patients. Conclusion Immunosenescence takes place in healthy donors and cancer patients. Our results suggest that in elderly tumor patients, the immune system is impaired and the tumor-induced immune escape is less pronounced. The increased expression of PD1 implies the potential for effective immunotherapies in elderly, as treatment with checkpoint inhibitors could be more beneficial for elderly HNSCC patients
