Background
Severe anaemia in children with cerebral malaria has been associated with respiratory distress secondary to lactic acidosis and/or hypoxia. The ensuing metabolic derangement may further depress the level of consciousness culminating in presentation with profound coma. This association has poorly been studied.Objective
To determine the relationship between profound coma at presentation and the presence of severe anaemia in children with cerebral malaria.Methods
This cross-sectional study involved 100 children with cerebral malaria who were consecutively recruited at admission in the Paediatric emergency unit of Mulago hospital in Uganda from July to December 2000. Clinical and laboratory evaluation was done using the hospital''s guidelines for the management of severe malaria. The exposure factor of interest was severe anaemia (Hb < 5.0 g/dl) and occurrence of profound coma (Blantyre coma Scale 0) was the outcome measure.Results
Severe anaemia and profound coma were seen in 20% and 9% of the children respectively. Severe anaemia was independently associated with profound coma, adjusted OR 1.34 (CI 1.17–1.95), p = 0. 002 and age < 3 years, adjusted OR 1.42 (CI 1.13–1.54), p = 0.001). Thirty percent of those with severe anaemia had deep sighing (acidotic) breathing compared to only 15% of those with haemoglobin (Hb) > 5 g/dl, OR 1.21 (CI 0.90–1.64), p = 0.118. There was no association between the malaria parasite density and severe anaemia. A similar proportion of those with severe anaemia regained consciousness within 24 hours compared to those with Hb > 5 g/dl (30 vs 42.5 %), OR 1.56 (0.65–3.71), p = 0.307.Conclusions
The findings suggest that profound coma in cerebral malaria may not only result from primary malaria encephalitis but possibly also from a metabolic dysfunction due to severe anaemia. 相似文献2.
Background
Oxygen saturation is a good marker for disease severity in emergency care. However, studies have not considered its use in identifying individuals infected with Plasmodium falciparum at risk of deaths.Objective
To investigate the prevalence and predictive value of hypoxaemia for deaths in under-5s with severe falciparum malaria infection.Methods
Oxygen saturation was prospectively measured alongside other indicators of disease severity in 369 under-5s admitted to a tertiary hospital in Nigeria. Participants were children in whom falciparum malaria parasitaemia was confirmed with blood film microscopy in the presence of any of the World Health Organization-defined life-threatening features for malaria.Results
Overall mortality rate was 8.1%. Of the 16 indicators of the disease severity assessed, hypoxaemia (OR=7.54; 95% CI=2.80, 20.29), co-morbidity with pneumonia (OR=19.27; 95% CI=2.87, 29.59), metabolic acidosis (OR=6.21; 95% CI=2.21, 17.47) and hypoglycaemia (OR=19.71; 95% CI=2.61, 25.47) were independent predictors of death. Cerebral malaria, male gender, wasting, hypokalaemia, hyponatriaemia, azotaemia and renal impairment were significantly associated with death in univariate analysis but not logistic regression model.Conclusions
Hypoxaemia predicts deaths in Nigerian children with severe malaria, irrespective of other features. Efforts should always be made to measure oxygen saturation as part of the treatments for severe malaria in children. 相似文献3.

Background
Malaria infections are a major public health problem in Africa and prompt treatment is one way of controlling the disease and saving lives.Methods
This cluster-randomised controlled community intervention conducted in 2003–2005 aimed at improving early malaria case management in under five children. Health workers were trained to train community-based women groups in recognizing malaria symptoms, providing first-line treatment for uncomplicated malaria and referring severe cases. Evaluation was through a pre- (2004) and a post-intervention survey (2005). Anaemia prevalence was the primary outcome.Results
1715 children aged 6–59 months were included in the pre-intervention survey and 2169 in the post-intervention survey. The prevalence of anaemia decreased significantly from 37% [95% CI 34.7–39.3] to 0.5% [95% CI 0.2–0.7] after the intervention (p<0.001); slightly more in the intervention (from 43.9% to 0.8%) than in the control (30.8% to 0.17%) group (p=0.038). Fever and reported fever decreased significantly and the mean body weight of the children increased significantly over the study period in both control and intervention groups.Conclusion
The decrease in anaemia was significantly associated with the intervention, whereas the fever and body weight trends might be explained by other malaria control activities or seasonal/climate effects in the area. The community intervention was shown to be feasible in the study context. 相似文献4.

Introduction
Since mid 1990s, Uganda has had an estimated 1.6 million internally displaced persons (IDPs) in the northern and eastern districts. A major cause of morbidity and mortality amongst children in displaced settings is protein energy malnutrition.Objective
To estimate the prevalence of and describe the risk factors for protein energy malnutrition among under five years old children living in internally displaced persons camps in Omoro county Gulu district.Methods
This was a cross sectional study undertaken among internally displaced people''s in Omoro county, Gulu district during 13 – 23rd September 2006. Anthropometric measurements of 672 children aged 3 – 59 months were undertaken and all their caretakers interviewed. The anthropometric measurements were analyzed using z-scores of height-for-age (H/A) and weight-for-height (W/H) indices. Qualitative data were collected through 6 focus group discussions, key informant interviews and observation. Data were captured using Epi Data version 3.0 and analyzed using EPI-INFO version 3.3.2 and SPSS version 12.0 computer packages respectively. ResultsThe prevalence of global stunting was found to be 52.4% and of global acute malnutrition 6.0%. Male children are at risk of being stunted Adjusted OR 1.57 95% CI 1.15–2.13; p value=0.004. Children in the age group 3 – 24 months were at risk of acute malnutrition Adjusted OR 2.78 95% CI 1.26–6.15; p value=0.012 while de-worming was protective Adjusted OR 0.44 95% CI 0.22–0.88; p value=0.018. The main sources of foodstuff for IDPs include food rations distributed by WFP, cultivation and purchase.Conclusion and Recommendations
There is high prevalence of protein energy malnutrition (stunting) among children in the internally displaced people''s camps in Gulu district. Male children are at an increased risk of stunting while children aged between 3 – 24 months are at an increased risk of suffering from acute malnutrition. Stakeholders including local government and relief organizations should intensify efforts to improve the nutritional status of IDPs especially children in the camp settings. The quantity of and access to household food supplies, health education on infant and child feeding and integrated management of childhood illnesses (IMCI) activities in the camps should be strengthened. 相似文献5.

Background
Malaria is the leading cause of morbidity and mortality in Uganda particularly among children under 5 years of age.Objectives
The study assessed the knowledge and practices on malaria prevention in 2 rural communities in Wakiso District, Uganda with emphasis on the various prevention methods.Methods
The study was a cross-sectional survey carried out among 376 households using both quantitative and qualitative methods. Log-binomial regression, chi square and Spearman''s rank order correlation were used to test for associations.Results
The majority of participants (64.6%) had low knowledge on malaria prevention methods, with untreated mosquito nets (81.7%), mosquito coils (36.9%) and insecticide treated nets (29.6%) being the most known methods. Knowledge on malaria prevention methods was associated with age (χ2 = 32.1; p < 0.01), employment status (χ2 = 18.1; p < 0.01), education (χ2 = 20.3; p = 0.01), income (χ2 = 14.5; p = 0.01) and having heard a malaria message in the previous 12 months (χ2 = 92.3; p < 0.01). Households that had at least one mosquito net were 45.5% and net ownership increased with household income. Only 0.5% of the houses had undergone indoor residual spraying in the previous 12 months, while 2.1% had complete mosquito proofing in windows and ventilators to prevent mosquito entry.Conclusion
There is potential to improve practices on malaria prevention by targeting other methods beyond mosquito nets such as installing proofing in windows and ventilators. The integrated approach to malaria prevention which advocates the use of several malaria prevention methods in a holistic manner should be explored for this purpose. 相似文献6.
Background
Methylenetetrahydrofolate (MTHFR) enzyme plays an important role in folate metabolism which is involved in DNA methylation, repair, and synthesis.Objective
We investigated if the MTHFR C677T polymorphism modulates the risk of developing breast cancer in Moroccan women.Methods
Genotyping was performed by PCR-RFLP method on a sample of 96 patients with breast cancer and 117 controls.Results
A positive correlation was found between the MTHFR C677T polymorphism and progesterone receptors expression (p= 0.04). According to menopausal status, the heterozygous CT (OR = 2.29 and P = 0.03) was statistically significant in pre-menopausal women. There was a significant association between C677T polymorphism and breast cancer risk in both additive (OR = 2.2, 95% CI = 1.24–3.86, p = 0.007) and dominant (OR = 2.10, CI 95% = 1.21–3.64, p = 0.008) models. In addition, the T allele were associated with a high breast cancer risk (OR = 1.59, 95% CI = 1.04–2.44, p = 0.03).Conclusion
In the light of our preliminary study, 677T allele and 677CT MTHFR genotype may represent a genetic determinant increasing breast cancer risk in Moroccan women. A larger study including a larger sample size and more information is needed to confirm our conclusions. 相似文献7.

Background
Preschool children have a high risk of poisoning. While medicines prescribed by primary care are potential poisoning agents, the risk factors for poisoning from medication are not well described.Aim
To identify risk factors for medicinal and non-medicinal poisoning in preschool children.Design and setting
Population-based nested case-control study using The Health Improvement Network primary care database 1988–2004.Method
Conditional logistic regression was used to identify child, maternal, and social risk factors for medicinal (1316 cases) and non-medicinal poisoning (503 cases), using 17 709 controls matched on general practice.Results
Poisoning by medicines was independently associated with deprivation (test for trend P<0.001), maternal age (P<0.001), birth order (P<0.001), maternal alcohol misuse (odds ratio [OR] = 5.44, 95% confidence interval [CI] = 1.99 to 14.91), and perinatal depression (OR = 1.54, 95% CI = 1.26 to 1.88). Living in a household with two or more adults lowered the odds of injury compared to single-parent households (OR = 0.85, 95% CI = 0.74 to 0.96) and the odds varied by age, being highest in 2 year olds (OR = 9.61, 95% CI = 7.73 to 11.95). Non-medicinal poisoning was associated with deprivation (P = 0.001), maternal age (P<0.001), and birth order (P<0.001). The odds were raised in 1 year olds (OR = 5.44, 95% CI = 4.07 to 7.26) and 2 year olds (OR = 5.07, 95% CI = 3.73 to 6.90) compared to those aged <1 year.Conclusion
Primary care data can be used to target interventions to children at risk of poisoning. This is pertinent when prescribing for children/family members, as prescribed medications may become poisoning agents. Prompt identification of maternal depression and alcohol misuse, and delivery of poisoning-prevention interventions at this stage may help prevent poisonings. 相似文献8.

Background
Guidelines describing symptoms in children that should alert GPs to consider cancer have been developed, but without any supporting primary-care research.Aim
To identify symptoms and signs in primary care that strongly increase the likelihood of childhood cancer, to assist GPs in selection of children for investigation.Design and setting
A population-based case-control study in UK general practice.Method
Using electronic primary care records from the UK General Practice Research Database, 1267 children aged 0–14 years diagnosed with childhood cancer were matched to 15 318 controls. Clinical features associated with subsequent diagnosis of cancer were identified using conditional logistic regression, and likelihood ratios and positive predictive values (PPVs) were estimated for each.Results
Twelve symptoms were associated with PPVs of ≥0.04%, which represents a greater than tenfold increase in prior probability. The six symptoms with the highest PPVs were pallor (odds ratio, OR = 84; PPV = 0.41% (95% confidence interval [CI] = 0.12% to 1.34%), head and neck masses (OR = 17; PPV = 0.30%; 95% CI = 0.10% to 0.84%), masses elsewhere (OR = 22; PPV = 0.11%; 95% CI = 0.06% to 0.20%), lymphadenopathy (OR = 10; PPV = 0.09%; 95% CI = 0.06% to 0.13%), symptoms/signs of abnormal movement (OR = 16; PPV = 0.08%; 95% CI = 0.04% to 0.14%), and bruising (OR = 12; PPV = 0·08%; 95% CI = 0.05% to 0.13%). When each of these 12 symptoms was combined singly with at least three consultations in a 3-month period, the probability of cancer was between 11 and 76 in 10 000.Conclusion
Twelve features of childhood cancers were identified, each of which increased the risk of cancer at least tenfold. These symptoms, particularly when combined with multiple consultations, warrant careful evaluation in general practice. 相似文献10.

Background
Disclosure of HIV status is important for optimal adherence to antiretroviral therapy in children. Identifying factors that affect disclosure of sero-status to children will help improve the process of disclosure. The purpose of the study was to determine the rate of HIV disclosure by the parents/caretakers to their children and other factors affecting disclosure.Methods
A cross sectional study among 174 caretakers of children age 5–8 years, twenty children and all (ten) health workers at Jinja Hospital paediatric HIV clinic. Data was collected with standardized questionnaires on socio-demographic factors, disclosure status, health facility factors, fears and perceived benefits of disclosure.Results
We found disclosure rates in 56% of the children. Among those not disclosed to, non-disclosure was 19% and deception 25%. Factors associated with disclosure of sero-status to a child were age of child (X2 37.4 df 1 p< 0.001), child being on antiretroviral therapy (OR 2.0 CI 1.1–3.6 p=0.024) and child attending psychosocial support group (OR 7.4 CI 3.6–15.3 p < 0.001). There were no appropriate guidelines on disclosure and only half of health providers had training on disclosure of HIV serostatus to children.Conclusion
The overall prevalence of disclosure was low. Psychosocial support groups promoted disclosure. 相似文献11.

Background
Sexually transmitted infections (STIs) remain a major public health problem in Zimbabwe. In Zvishavane, STI increased from 66 per 1,000 in 2002 to 97 per 1,000 in 2005, a 31% increase in cases.Objective
To determine the factors associated with contracting sexually transmitted infections (STI) among patients in Zvishavane.Methods
A frequency matched case control study was conducted. Cases were persons above 15 years diagnosed with STI at three health facilities in Zvishavane urban. Controls were patients who visited the same facilities for other ailments. We interviewed 77 cases and 154 controls.Results
Both cases and controls were knowledgeable about STI. Risk factors for men included sex under the influence of alcohol OR=7.11 (95% CI 2.42–20.85), relationships less than one year, OR= 9.33 (95% CI 3.53–24.70), no condom use at first intercourse OR=5.17 (95% CI 1.64–16.25) and paying for sex OR= 23.65 (95% CI 6.23–89.69). For females the risk factors were non-use of condom at first intercourse OR=2.49 (95% CI 1.02–6.04) and relationships less than one year OR=3.19 (95% CI 1.41–7.23).Significant differences in attitudes were evident among cases and controls.Conclusion
Knowledge of STI did not provide protection from STI diagnosis. Limiting the number of partners, consistent condom use, and fidelity are important for both men and women. 相似文献12.

OBJECTIVE
To investigate whether early weaning constitutes a risk factor for overweight at preschool age and to identify other factors that affect this association.METHODS
This was a case-control study of 366 children aged 2 to 6 years (176 boys and 190 girls) from three cities. The case group comprised overweight children, as defined by body mass index (BMI) for age greater than or equal to the 85th percentile. The main exposure analyzed was early weaning (exclusive or predominant breastfeeding for less than four months).RESULTS
Early weaning was a significant risk factor for overweight in univariate analysis (OR = 1.69; 95% CI: 1.10–2.60; p = 0.02), but not in multivariate analysis (OR = 1.42; 95% CI: 0.86–2.34; p = 0.17). Maternal overweight, birth weight ≥ 3,500 g and sedentarism were the main risk factors for overweight in multivariate analysis.DISCUSSION
In our study, the protective effect of breastfeeding against overweight was only shown in univariate analysis; it did not persist after controlling for other variables. It is possible that breastfeeding has only a small protective role against overweight in comparison with other variables of greater importance.CONCLUSION
Our results suggest that the potential protective effect of breastfeeding against overweight among preschool children is weaker than genetic and other environmental factors. 相似文献13.

Background
In the UK, approximately five people are diagnosed with Hodgkin lymphoma (HL) daily. One-tenth of diagnoses are in those aged >75 years.Aim
To establish a symptom profile of HL and quantify their risk in primary care patients aged ≥40 years.Design and setting
Matched case–control study using Clinical Practice Research Datalink patient records.Method
Putative clinical features of HL were identified in the year before diagnosis. Results were analysed using conditional logistic regression and positive predictive values (PPVs) calculated for the consulting population.Results
Two-hundred and eighty-three patients aged ≥40 years, diagnosed with HL between 2000 and 2009, and 1237 age, sex, and general practice-matched participants were studied. Six features were independently associated with HL: lymphadenopathy (OR 280, 95% confidence interval [CI] = 25 to 3100), head and neck mass not described as lymphadenopathy (OR 260, 95% CI = 21 to 3200), other mass (OR 12, 95% CI = 4.4 to 35), thrombocytosis (OR 6.0, 95% CI = 2.6 to 14), raised inflammatory markers (OR 5.2, 95% CI = 3.0 to 9.0), and low full blood count (OR 2.8, 95% CI = 1.6 to 4.8). Lymphadenopathy per se has a positive predictive value (PPV) of 5.6% for HL in patients aged ≥60 years.Conclusion
Consistent with secondary care findings, lymphadenopathy is the clinical feature with the highest risk of HL in primary care and warrants urgent investigation. 相似文献14.
Background
Malaria is a leading cause of mortality in Uganda accounting for 25% of deaths among children. Hitherto no adjunct therapy has been identified to improve outcome of cerebral malaria. Retinol suppresses growth of P.falciparum, scavenges free radicals, and exhibits synergistic action with quinine in parasite clearance.Objective
To determine the effect of vitamin A supplementation on treatment outcome of cerebral malariaMethods
In this randomised double-blind placebo controlled clinical trial we studied 142 children aged 6–59 months admitted with cerebral malaria in Mulago Hospital, Kampala. Children were randomised to either vitamin A or placebo and followed for 7 days. The main outcome measures were coma recovery time, time for convulsions to stop, and parasite and fever clearance. Secondary outcomes were overall mortality and time taken to start oral feeds.Results
There was no difference in the coma recovery time (p=0.44), resolution of convulsions (p=0.37), fever clearance (p=0.92), parasite clearance (p=0.12), and starting oral feeds between the two treatment groups. Mortality was higher (16.2%) in the placebo than in the vitamin A group (8.1%): RR 1.4; 95% CI 1.0–2.1.Conclusions
Vitamin A as adjunct therapy did not significantly reduce coma duration but there were fewer deaths in the vitamin A arm. 相似文献15.
Background
Hepatitis viral infections are major health challenge leading to high morbidity and mortality worldwide.Objectives
Although the magnitude of hepatitis in Pakistan has been well documented, information regarding the prevalence of hepatitis C virus (HCV) infection in Faisalabad, Pakistan is scarce. The present retrospective study was undertaken to determine the epidemiology of HCV in Faisalabad, Pakistan.Methods
Between May, 2010 and December, 2012, medical records of 39780 subjects visiting sexually transmitted infections (STIs) clinic, district headquarter (DHQ) hospital, Faisalabad, Pakistan were reviewed. Regression analysis was used to determine independent risk factorsResults
HCV prevalence was 21.99%. With mean age of 49.5 ± 2.7 years (range 27–63 years), majority (67.15%) of the individuals were male. Marital status and low literacy rates were associated with HCV (P<0.05). Reference to the potential risk factors, the injection drug use was the major mode (72.77%) of infection transmission. Age (OR 1.5, 95% CI 1.2–1.9), male gender (OR 1.2, 95% CI 0.9–1.6) and injection use (OR 1.9, 95% CI 1.0–2.7) were significantly associated with HCV.Conclusions
Most important finding was higher HCV prevalence in Faisalabad region as compared to the previous assessments that demands an urgent need for preventive intervention strategies. 相似文献16.

Background
The economic crisis of 2009 led to a wave of corporate reorganisations and bankruptcies, with many dismissals of employees. GPs were confronted with subsequent health consequences.Aim
To assess the possible relationship between losing one’s job and having suicidal thoughts.Design and setting
A survey of patients aged 18–49 years recruited from GP practices in Belgium in Deurne (Flemish region) and La Louvière (Walloon region) from September to December 2010.Method
Anonymous self-administered questionnaire.Results
Of all eligible patients (n = 1818), 831 were offered the questionnaire and 377 completed it (45.4%). More than one in five had been confronted with employment loss in the past year (the responder or someone close losing their job). Almost one in ten had lost their job themselves in the past year. More than one in four had experienced suicidal thoughts and 11.7% had seriously considered ending their life in the past year. In the logistic regression analysis, the following characteristics showed a statistically significant relationship with having suicidal thoughts: being single (odds ratio [OR] = 4.8, 95% confidence interval [CI] = 1.7 to 13.8), not having satisfying social contacts (OR = 5.1, 95% CI = 1.6 to 16.2), having depressive complaints (OR = 18.4, 95% CI = 5.8 to 58.4), and having lost one’s employment in the past year (OR = 8.8, 95% CI = 2.0 to 39.3).Conclusion
This study points to a statistically significant relationship between losing one’s employment in the past year and having suicidal thoughts. It emphasises the important role of the GP in the continuous and reinforced assessment of suicidal risk in times of recession. 相似文献17.

Background
Non-Hodgkin lymphoma (NHL) is the sixth most common cancer in the UK; approximately 35 people are diagnosed and 13 die from the disease daily.Aim
To identify the primary care clinical features of NHL and quantify their risk in symptomatic patients.Design and setting
Matched case–control study using Clinical Practice Research Datalink patient records.Method
Putative clinical features of NHL were identified in the year before diagnosis. Results were analysed using conditional logistic regression and positive predictive values (PPVs).Results
A total of 4362 patients aged ≥40 years, diagnosed with NHL between 2000 and 2009, and 19 468 age, sex, and general practice-matched controls were studied. Twenty features were independently associated with NHL. The five highest risk symptoms were lymphadenopathy, odds ratio (OR) 263 (95% CI = 133 to 519), head and neck mass not described as lymphadenopathy OR 49 (95% CI = 32 to 74), other mass OR 12 (95% CI = 10 to 16), weight loss OR 3.2 (95% CI = 2.3 to 4.4), and abdominal pain OR 2.5 (95% CI = 2.1 to 2.9). Lymphadenopathy has a PPV of 13% for NHL in patients ≥60 years. Weight loss in conjunction with repeated back pain or raised gamma globulin had PPVs >2%.Conclusion
Unexplained lymphadenopathy in patients aged ≥60 years produces a very high risk of NHL in primary care. These patients warrant urgent investigation, potentially sooner than 6 weeks from initial presentation where the GP is particularly concerned. 相似文献19.
