Introduction: due to the inability of low-income populations to access nutritious foods or basic education, these groups usually consume unhealthy diets, which frequently lead to nutrition issues like obesity, malnutrition, and other health morbidities. The purpose of the study was to evaluate the nutritional knowledge, dietary practices, nutritional status, and factors influencing the dietary habits of low-income persons living in a rural constituency in Southern Nigeria., Methods: a cross-sectional study was carried out on 419 consenting low-income adults (18 years and older) using a simple random technique, in order to collect data on their socio-demographic traits, nutritional knowledge, dietary practices, and nutritional status. Statistical Package for Social Sciences (SPSS) version 22.0 was used to analyze the data generated., Results: the respondents´ the average age was 40.9 ± 15.68 years while 224 (53.5%) of those surveyed were females. The proportion of responders with a secondary education was highest 279 (66.6%). The most common occupation among respondents was farming 151 (36.1%) and petty trading 135 (32.2%). Overall, 314 (74.9%) of low-income adults had poor dietary habits, and 245 (60.6%) had poor nutrition knowledge. Occupation and gender were significantly associated with nutritional status P<0.05. The majority of respondents 56.2% (235) were overweight or obese, and multivariate logistic regression analysis shows that respondents with concern about gaining weight were more likely to be overweight or obese (OR=1.065, 95% CI=0.832-1.363)., Conclusion: the findings from the study indicate that inadequate nutritional knowledge and poor dietary habits, reflected in respondents' body weight are likely to increase the risk of non-communicable diseases, necessitating the need for nutritional education among rural populations., Competing Interests: The authors declare no competing interests., (Copyright: Ogbolu Nneka Christabel et al.)

Though local structures in ionic liquids are dominated by strong Coulomb forces, directional hydrogen bonds can also influence the physicochemical properties of imidazolium-based ionic liquids. In particular, the C-2 position of the imidazolium cation is acidic and can bind with suitable hydrogen bond acceptor sites of molecular solvents dissolved in imidazolium-based ionic liquids. In this report, we identify hydrogen-bonded microenvironments of the model ionic liquid, 1-ethyl-3-methylimidazolium tris(pentafluoroethyl) trifluorophosphate, and the changes that occur when molecular solvents are dissolved in it by using a C-D infrared reporter at the C-2 position of the cation. Our linear and nonlinear infrared experiments, along with computational studies, indicate that the molecular solvent dimethyl sulfoxide can form strong hydrogen-bonded dimers with the cation of the ionic liquid at the C-2 position. In contrast, acetone, which is also a hydrogen bond acceptor similar to dimethyl sulfoxide, does not show evidence of cation-solvent hydrogen-bonded conformers at the C-2 position. The outcome of our study on a broad scale strengthens the importance of cation-solute interactions in ionic liquids.

Aims: To examine whether stroke care processes and outcomes are improved following the institution of an acute stroke unit (ASU) at a medium-sized New Zealand hospital., Methods: Two retrospective audits over 12-month periods were carried out at Hutt Valley Hospital before and after the institution of a 6-bed ASU. Data was collected on demographics, length of stay, stroke type, investigations, processes of care and outcomes., Results: 139 strokes pre ASU and 155 strokes post ASU were studied. 86.8% of strokes received stroke unit care in the 2009 audit. There were more intracerebral haemorrhages in 2006 (17.2% vs. 9.0%). Significant improvements were seen between 2006 and 2009 in time to aspirin administration (52.7 versus 14.5 hours), swallow assessment within 24 hours (88.5% versus 96.1%), lag time to carotid Doppler studies (21 days versus 4.5 days), pressure risk assessments (19.6%, versus 87.2%) and urinary infection rates (10.8% versus 2.0% ). Total length of stay (TLOS) and mortality were reduced but the difference was not statistically significant. (20.5 days versus 18.3 days p=0.34, Inpatient mortality 16.2% versus 10% p=0.12)., Conclusions: The introduction of an ASU has resulted in improvements in several key processes of stroke care. Overall mortality and total length of stay showed a trend to improvement after the establishment of an ASU.

Immunological studies were carried out on 7 neonates maintained on total parenteral nutrition for periods ranging from 14 to 31 days after surgery for correction of gastrointestinal anomalies. IgM and IgA levels were high in all patients but IgG levels were low, compared with normal values. Total leucocyte counts, absolute lymphocyte counts, and T- and B-lymphocytes in all patients were similar to those of healthy controls. Neonates maintained on adequate total parenteral nutrition showed no evidence of impairment of immune function.

The T lymphocytes populations of 22 young healthy adults, 21 healthy middle aged and older blood donors, 35 non-pregnant women of child bearing age and 14 patients with advanced malignant disease were assessed and compared. It was found that the mean T cell counts in the middle aged and older controls were significantly lower than in the healthy young adults and were further reduced in the patients with malignant disease. The addition of the proteolytic agent brinase (protease 1 obtained from Aspergillus oryzae) to the rosetting test increased the T cell counts signficantly in all groups. This was mot marked in the older age groups and the patients with malignant disease. The proteolytic agent is shown to exert its effect on the lymphocytes in the test. Slow intravenous infusion of either brinase or streptokinase into patients with malignant disease is shown to result in increased T lymphocyte counts pari passu with a restoration of skin allergy. The significance of these findings and possible mode of action of the proteolytic agents in increasing T cell activity are discussed.

Fourteen neonates born with congenital malformations were investigated for lymphocyte function before and after surgery. Total leucocyte and absolute lymphocyte counts were unaltered after surgery. The mean percentage of T-lymphocytes observed either pre- or postoperatively was considerably lower than that reported in older children and adults. While there was an increase in the percentage of B-lymphocytes after operation in the infants, the absolute number of B-cells remained unchanges. The preoperative transformation response of lymphocytes to PHA (mean 12.9 +/- 5.4 X 10(3) counts/min) was little different from the postoperative values (mean 12.4 +/- 4.4 X 10(3) counts/min). These results suggest that the neonate is immunologically different from older children and adults in its response to anaesthesia and surgery.

Nephrotic syndrome has been observed in association with different types of neoplasia. This appears to be the first report of the occurrence of the nephrotic syndrome due to membrano proliferative glomerulonephritis in association with carcinoma of the oesophagus. Although proteinuria was present before excision of the tumour, the nephrotic phase occurred subsequently. Eventually it disappeared leaving the patient with a clear urine and biochemical and histological improvement of the renal lesion (including immunofluorescent and electronmicroscopy studies). Possible mechanisms responsible for the nephrotic syndrome in this case are discussed.
