Cost utility of lateral-flow urine lipoarabinomannan for tuberculosis diagnosis in HIV-infected African adults

SETTING

In-patient hospitals in South Africa and Uganda.

OBJECTIVE

To evaluate the cost-effectiveness of a lateral-flow urine lipoarabinomannan (LAM) test when added to existing strategies for tuberculosis (TB) diagnosis in human immunodeficiency virus infected adults (CD4(+) T-cell counts < 100 cells/l) with symptoms of active TB.

DESIGN

Decision-analytic cost-utility model, with the primary outcome being the incremental cost-effectiveness ratio, expressed in 2010 US dollars per disability-adjusted life year (DALY) averted from the perspective of a public sector TB control program.

RESULTS AND CONCLUSION

For every 1000 patients tested, adding lateral-flow urine LAM generated 80 incremental appropriate anti-tuberculosis treatments and averted 224 DALYs. Estimated cost utility was US$353 per DALY averted (95% uncertainty range $192$1161) in South Africa and $86 per DALY averted (95% uncertainty range $49$239) in Uganda, reflecting the lower treatment costs in Uganda. Cost utility was most sensitive to assay specificity, cost of anti-tuberculosis treatment, life expectancy after TB cure and cohort TB prevalence, but did not rise above $1500 per DALY averted in South Africa under any one-way sensitivity analysis. The probability of acceptability was >99.8% at a per-DALY willingness-to-pay threshold equal to the per capita gross domestic product in South Africa ($7275) and Uganda ($509).

Solid lipid nanoparticles of a water soluble drug, ciprofloxacin hydrochloride

The aim of this study was to understand and investigate the relationship between experimental factors and their responses in the preparation of ciprofloxacin hydrochloride based solid lipid nanoparticles. A quadratic relationship was studied by developing central composite rotatable design. Amount of lipid and drug, stirring speed and stirring time were selected as experimental factors while particle size, zeta potential and drug entrapment were used as responses. Prior to the experimental design, a qualitative prescreening study was performed to check the effect of various solid lipids and their combinations. Results showed that changing the amount of lipid, stirring speed and stirring time had a noticeable influence on the entrapment efficiencies and particle size of the prepared solid lipid nanoparticles. The particle size of a solid lipid nanoparticle was in the range of 159-246 nm and drug encapsulation efficiencies were marginally improved by choosing a binary mixture of physically incompatible solid lipids. Release of ciprofloxacin hydrochloride from solid lipid nanoparticle was considerably slow, and it shows Higuchi matrix model as the best fitted model. Study of solid lipid nanoparticle suggested that the lipid based carrier system could potentially be exploited as a delivery system with improved drug entrapment efficiency and controlled drug release for water soluble actives.

Fulminant hepatic failure due to dengue

Dengue Fever (DF) is only rarely considered as a cause of acute liver failure even globally and only a few case reports of acute hepatic failure and encephalopathy occurring in DF in adults are available. We report a case of Acute Liver Failure due to Dengue during a major outbreak in 2010 in Chitwan. A 20 year old previously healthy female presented to the emergency department of Chitwan Medical College with fever, jaundice and altered sensorium. She was tested positive for Dengue IgM. Her biochemical and clinical parameters were suggestive of acute liver failure with total billirubin of 10.1 mg/dL, direct billirubin of 5.2 mg/dL, ALT 5760 IU, AST 14100 IU, alkaline phosphatase of 1250 IU, PT INR of 1.76 and platelet count of 30,000/mm3. Other causes for acute hepatic failure like acute viral hepatitis, leptospirosis, malaria, Reyes syndrome were ruled out. The patient was admitted and managed in the ICU with supportive care and platelet transfusion. With treatment she made a significant clinical and biochemical improvement with AST of 105 IU, ALT of 120 IU and platelet count of 150,000/mm3. She was discharged after 11 days of hospital stay.

Mice lacking AMP-activated protein kinase α1 catalytic subunit have increased bone remodelling and modified skeletal responses to hormonal challenges induced by ovariectomy and intermittent PTH treatment

AMP-activated protein kinase (AMPK) is a key regulator of cellular and body energy homeostasis. We previously demonstrated that AMPK activation in osteoblasts increases in vitro bone formation while deletion of the Ampkα1 (Prkaa1) subunit, the dominant catalytic subunit expressed in bone, leads to decreased bone mass in vivo. To investigate the cause of low bone mass in the Ampkα1(-/-) mice, we analysed bone formation and resorption in the tibia of these mice by dynamic histomorphometry and determined whether bone turnover can be stimulated in the absence of the Ampkα1 subunit. We subjected 12-week-old Ampkα1(+)(/)(+) and Ampkα1(-/-) mice to ovariectomy (OVX), intermittent PTH (iPTH) administration (80 μg/kg per day, 5 days/week) or both OVX and iPTH hormonal challenges. Tibiae were harvested from these mice and bone micro-architecture was determined by micro-computed tomography. We show for the first time that Ampkα1(-/-) mice have a high bone turnover at the basal level in favour of bone resorption. While both Ampkα1(+)(/)(+) and Ampkα1(-/-) mice lost bone mass after OVX, the bone loss in Ampkα1(-/-) mice was lower compared with controls. iPTH increased trabecular and cortical bone indexes in both ovariectomised Ampkα1(+)(/)(+) and Ampkα1(-/-) mice. However, ovariectomised Ampkα1(-/-) mice showed a smaller increase in bone parameters in response to iPTH compared with Ampkα1(+)(/)(+) mice. By contrast, non-ovariectomised Ampkα1(-/-) mice responded better to iPTH treatment than non-ovariectomised Ampkα1(+)(/)(+) mice. Overall, these data demonstrate that Ampkα1(-/-) mice are less affected by changes in bone turnover induced by OVX but respond better to the anabolic challenge induced by iPTH. These results suggest that AMPKα1 activation may play a role in the hormonal regulation of bone remodelling.

Intravitreal ranibizumab for the treatment of choroidal neovascularisation secondary to angioid streaks

AIMS

To assess the medium to long-term efficacy and safety of intravitreal ranibizumab for the treatment of choroidal neovascularisation (CNV) secondary to angioid streaks (AS).

METHODS

A total of 12 eyes of nine patients treated with intravitreal ranibizumab (0.5 mg in 0.05 ml) for CNV secondary to AS were retrospectively identified. Efficacy of treatment was determined by changes in best-corrected LogMAR visual acuity (BCVA) and optical coherence tomography. Changes with respect to baseline BCVA were defined as improved or reduced with a gain or loss of more than 10 letters, respectively, or stable if remaining within 10 letters.

RESULTS

Over a mean follow-up of 21.75 months (range: 1-54), patients received mean 5.75 (range: 2-15) intravitreal ranibizumab injections per affected eye. BCVA improved in three eyes (25%), stabilised in eight eyes (66.67%), and deteriorated in one eye (8.33%). There was no significant change in central retinal thickness (CRT) over the follow-up period (P=0.1072). No drug-related systemic side effects were recorded.

CONCLUSION

The long-term treatment of CNV secondary to AS with intravitreal ranibizumab showed a stabilisation in CRT and an improvement or stabilisation of BCVA. The absence of systemic side effects was reassuring. Further long-term prospective studies are required to validate these findings.

An individual coding polymorphism and the haplotype of the SPARC gene predict gastric cancer recurrence

The 5-year survival rate for gastric adenocarcinoma (GA) remains only 40% and biomarkers to identify patients at high risk of tumor recurrence are urgently needed. Secreted protein acidic and rich in cysteine (SPARC) is an extracellular matrix glycoprotein that mediates cell matrix interactions, and upregulation of SPARC can promote tumor progression and metastasis. This study investigated whether single-nucleotide polymorphisms (SNPs) in SPARC impact the prognosis of GA. Blood or formalin-fixed, paraffin-embedded tissues were obtained from 137 GA patients at the University of Southern California and Memorial Sloan-Kettering Cancer Center medical facilities. DNA was isolated and five SNPs in the SPARC 3'-untranslated region (UTR) were evaluated by DNA sequencing or PCR-restriction fragment length polymorphism. Associations between SNPs and time to tumor recurrence (TTR) were analyzed using Kaplan-Meier curves, log-rank tests, and likelihood-ratio test within logistic or Cox regression model as appropriate. Patients carrying at least one G allele of the SPARC rs1059829 polymorphism (GG, AG) showed a median TTR of 3.7 years compared with 2.1 years TTR for patients with AA (hazard ratio (HR) 0.57; P=0.033). In a multivariate analysis adjusted for T and N category as covariates and stratified by race, hospital and chemotherapy, patients with at least one SPARC rs1059829 G allele (GG, AG) remained significantly associated with superior TTR than patients with AA genotype (adjusted P=0.026). In addition, patients harboring the G-A-A haplotype had the highest risk of tumor recurrence (HR 1.892; adjusted P=0.016). Our findings suggest that SPARC 3'-UTR SNPs may be useful in predicting GA patients at increased risk of recurrence.

Smouldering systemic mastocytosis presenting with cryptic life-threatening crises: case report and literature review

Systemic mastocytosis (SM) is a rare, clonal disorder of the mast cell (MC) and its precursor cells. It is characterized by proliferation and accumulation of MCs within various organs, most commonly the skin. The clinical course is variable with indolent or smouldering and aggressive forms being described. We report the case of a middle-aged male patient with smouldering SM presenting with atypical recurrent life-threatening crises. The patient reported a 19-year history of chronic symptoms. The patient had four inpatient stays due to atypical life-threatening crises, during which he has shown end organ damage (cardiac and renal). With each crisis the patient reported acute symptoms. The management of each of these episodes was complex and made more challenging by the patient's longstanding history of hypertension and ischaemic heart disease. In short, SM can present with unexplained life-threatening crises which can be confused for an infectious disease being acute in nature.

Cardiovascular risk assessment of South Asians in a religious setting: a feasibility study

AIMS

South Asians in the UK have high cardiovascular disease (CVD) mortality. Therefore, this population is likely to benefit from screening programmes. To address this issue, an initiative was set up between the Royal Free Hampstead NHS Trust, H.E.A.R.T. UK and two Hindu temples in North London to provide screening for CVD risk factors in the community.

METHODS

A total of 434 individuals of Gujarati Indian origin were screened. Measurements included anthropometry, blood pressure and lipid profiles. Three different scoring systems: Framingham, Joint British Societies' 2 and QRISK2 were used to estimate CVD risk.

RESULTS

At least one modifiable CVD risk factor was present in 92% of the individuals screened; 52% were hypertensive, 40% were obese, 75% had central adiposity and 10% had total cholesterol/high density lipoprotein cholesterol ratio > 6. In addition, 37% of a subset of 104 individuals with a fasting sample fulfilled the diagnostic criteria for metabolic syndrome. Overall, 15% of participants screened had a 10-year CV risk score > 20% using QRISK2. The three risk score calculators showed moderate agreement: QRISK2 and JBS2 (kappa 0.61, 95% CI 0.54-0.67), QRISK2 and Framingham (kappa 0.63, 95% CI 0.57-0.70) and JBS2 and Framingham (kappa 0.70, 95% CI 0.64-0.75).

CONCLUSIONS

A high prevalence of modifiable risk factors for CVD was detected in the population screened.

AMP-activated protein kinase pathway and bone metabolism

There is increasing evidence that osteoporosis, similarly to obesity and diabetes, could be another disorder of energy metabolism. AMP-activated protein kinase (AMPK) has emerged over the last decade as a key sensing mechanism in the regulation of cellular energy homeostasis and is an essential mediator of the central and peripheral effects of many hormones on the metabolism of appetite, fat and glucose. Novel work demonstrates that the AMPK signaling pathway also plays a role in bone physiology. Activation of AMPK promotes bone formation in vitro and the deletion of α or β subunit of AMPK decreases bone mass in mice. Furthermore, AMPK activity in bone cells is regulated by the same hormones that regulate food intake and energy expenditure through AMPK activation in the brain and peripheral tissues. AMPK is also activated by antidiabetic drugs such as metformin and thiazolidinediones (TZDs), which also impact on skeletal metabolism. Interestingly, TZDs have detrimental skeletal side effects, causing bone loss and increasing the risk of fractures, although the role of AMPK mediation is still unclear. These data are presented in this review that also discusses the potential roles of AMPK in bone as well as the possibility for AMPK to be a future therapeutic target for intervention in osteoporosis.

Feature Selection with Conjunctions of Decision Stumps and Learning from Microarray Data

One of the objectives of designing feature selection learning algorithms is to obtain classifiers that depend on a small number of attributes and have verifiable future performance guarantees. There are few, if any, approaches that successfully address the two goals simultaneously. To the best of our knowledge, such algorithms that give theoretical bounds on the future performance have not been proposed so far in the context of the classification of gene expression data. In this work, we investigate the premise of learning a conjunction (or disjunction) of decision stumps in Occam's Razor, Sample Compression, and PAC-Bayes learning settings for identifying a small subset of attributes that can be used to perform reliable classification tasks. We apply the proposed approaches for gene identification from DNA microarray data and compare our results to those of the well-known successful approaches proposed for the task. We show that our algorithm not only finds hypotheses with a much smaller number of genes while giving competitive classification accuracy but also having tight risk guarantees on future performance, unlike other approaches. The proposed approaches are general and extensible in terms of both designing novel algorithms and application to other domains.

Evaluation of nurse providers of comprehensive abortion care using MVA in Nepal

BACKGROUND

Although Nepal's maternal mortality ratio has fallen over the past decade, unsafe abortion remains a leading cause of maternal morbidity and mortality. A key strategy for improving access to safe abortion services is to train mid-level providers such as nurses in comprehensive abortion care (CAC). The Family Health Division of the Nepal Ministry of Health trained an initial cohort of 96 nurses to provide first trimester CAC services using manual vacuum aspiration (MVA) between September 2006 and July 2009. This study evaluates the acceptability and quality of CAC services provided by trained nurses in Nepal.

METHODS

Five assessments were used to evaluate post-training service provision on CAC: facility logbooks registry, nurse provider interviews, facility assessments, facility manager interviews and procedure observation checklists. Ninety-two nurses from 50 facilities participated in the evaluation. Descriptive statistics are reported.

RESULTS

Overall, 5,600 women received CAC services from 42 facilities where nurses were providing services between June 2009 and April 2010. Complications were experienced by 68 surgical abortion clients (1.6%) and 12 medical abortion clients (1.2%). All nurses reported that clients were happy to receive care from them, and 67% of facility managers reported that clients preferred nurse providers over physicians or had no preference. Facility managers and nurses reported a need for additional support, including further training and improved drug and equipment supply.

CONCLUSIONS

Trained nurses provide high quality CAC services in Nepal. Additional support in the form of facilitative supervision and training should be considered to strengthen CAC service provision.

QuantiFERON-TB Gold In-Tube for the detection of Mycobacterium tuberculosis infection in children with household tuberculosis contact

SETTING

Improved strategies are needed for detecting Mycobacterium tuberculosis infection in children in TB-endemic settings.

OBJECTIVE

To determine the prevalence of M. tuberculosis infection by tuberculin skin testing (TST) and by the QuantiFERON-TB Gold In-Tube (QFT-GIT) test in children with an adult household contact with pulmonary TB in South Africa.

DESIGN

Cross-sectional study.

RESULTS

A total of 167 adult pulmonary TB cases (153/167, 92% human immunodeficiency virus [HIV] infected) and 270 pediatric contacts (median age 6 years, 14/270, 5% HIV-infected) were enrolled. All children completed QFT-GIT testing and 254 (94.1%) completed TST testing. Prevalence of M. tuberculosis infection was 28% (71/254, 95%CI 23-34) using TST (5 mm cut-off) and 29% (79/270, 95%CI 24-35) using QFT-GIT (P = 0.49). Agreement between TST and QFT-GIT was 81% (kappa 0.58). Nineteen (7%) QFT-GIT results were indeterminate. Children aged <2 years were more likely than older children to have indeterminate QFT-GIT results (aOR 5.7, 95%CI 1.5-22, P = 0.01) and discordant QFT-GIT and TST results (aOR 3.5, 95%CI 1.7-7.6, P = 0.001).

CONCLUSION

Prevalence of M. tuberculosis infection in pediatric contacts was high regardless of the diagnostic method used. TST should not be excluded for the detection of pediatric M. tuberculosis infection in this setting, but QFT-GIT may be a feasible alternative in children aged ≥ 2 years.

A pilot study to investigate the effect of plate size on meal energy intake in normal weight and overweight/obese women

BACKGROUND

Smaller plates are often recommended as a strategy for controlling energy intake; however, the effect of plate size on meal energy intake in normal weight compared to overweight or obese individuals is not known. The present study aimed to investigate this further.

METHODS

Ten normal weight [mean (SD) body mass index, 21.7 (2.0) kg m(-2) ] and 10 overweight or obese [31.7 (3.6) kg m(-2) ] women attended a metabolic laboratory on two separate days for lunch. In this cross-over study, subjects were randomly assigned to eat lunch using either a small (21.6 cm) or a large (27.4 cm) plate. Each subject self-served spaghetti mixed with tomato sauce from an individual serving bowl onto the assigned plate, and ate until satisfied. The meal was consumed alone at a private table. During the second study day, each subject underwent the same procedure but used the alternate size plate. The amount eaten and energy consumed were calculated and a mixed effects analysis of variance model was used to compare energy intakes.

RESULTS

Energy intakes using the small and large plate were 1356 (515) and 1365 (393) kJ, respectively, in normal weight subjects and 1314 (632) and 1226 (431) kJ, respectively, in overweight/obese subjects. Neither plate size, nor plate size by weight status significantly affected meal energy intake. There was no plate size by weight status effect on ratings of palatability, hunger, satiety, fullness or prospective consumption.

CONCLUSIONS

Plate size did not affect energy intake from a single meal in either the normal weight or overweight/obese subjects.

Effectiveness of low-temperature domestic laundry on the decontamination of healthcare workers' uniforms

OBJECTIVE

Most professionals in the healthcare environment wear uniforms. For the purpose of this study, we concentrated on nurses' uniforms. In the United Kingdom, many nurses are expected to launder their uniforms at home by using a domestic washing machine that frequently has low-temperature wash cycles. We have investigated whether the use of low-temperature wash cycles results in a microbiologically acceptable product to wear on the wards.

METHODS

We have assessed the bioburden on uniforms before and after laundry and the effectiveness of low-temperature wash cycles and ironing on removal of methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter baumannii. We did not assess the role of tumble drying.

RESULTS

We demonstrate contamination of uniforms by gram-negative bacteria after wash, the removal of MRSA at low-temperature wash cycles in the presence of detergent, and the eradication of gram-negative bacteria after ironing.

CONCLUSIONS

Our conclusions are that laundry in a domestic situation at 60°C (140°F) for 10 minutes is sufficient to decontaminate hospital uniforms and reduces the bacterial load by more than 7-log reduction, that items left in the pockets are decontaminated to the same extent, that the addition of either a biological detergent or a nonbiological detergent is beneficial in removing MRSA from experimentally contaminated swatches, and that uniforms become recontaminated with low numbers of principally gram-negative bacteria after laundry but that these are effectively removed by ironing.

A randomized trial of hypothesis-driven vs screening neurologic examination

OBJECTIVE

We hypothesized that trainees would perform better using a hypothesis-driven rather than a traditional screening approach to the neurologic examination.

METHODS

We randomly assigned 16 medical students to perform screening examinations of all major aspects of neurologic function or hypothesis-driven examinations focused on aspects suggested by the history. Each student examined 4 patients, 2 of whom had focal deficits. Outcomes of interest were the correct identification of patients with focal deficits, number of specific deficits detected, and examination duration. Outcomes were assessed by an investigator blinded to group assignments. The McNemar test was used to compare the sensitivity and specificity of the 2 examination methods.

RESULTS

Sensitivity was higher with hypothesis-driven examinations than with screening examinations (78% vs 56%; p = 0.046), although specificity was lower (71% vs 100%; p = 0.046). The hypothesis-driven group identified 61% of specific examination abnormalities, whereas the screening group identified 53% (p = 0.008). Median examination duration was 1 minute shorter in the hypothesis-driven group (7.0 minutes vs 8.0 minutes; p = 0.13).

CONCLUSIONS

In this randomized trial comparing 2 methods of neurologic examination, a hypothesis-driven approach resulted in greater sensitivity and a trend toward faster examinations, at the cost of lower specificity, compared with the traditional screening approach. Our findings suggest that a hypothesis-driven approach may be superior when the history is concerning for an acute focal neurologic process.

An unusual presentation of aggressive fibromatosis (retroperitoneal desmoid tumour) in pelvic cavity presented as obstructed labour

Retroperitoneal desmoid tumours are uncommon tumours usually occurring in young females in their reproductive age group and commonly have a benign course but sometimes they can become malignant. These tumours belong to family of myofibroblastic fibromatosis. These tumours are composed of fibroblastic cells with bands of collagen and ill defined cytoplasm and rarely show mitosis. Recurrence is common especially after incomplete excision. Retroperitoneal desmoid is an uncommon tumour among desmoid group which led to an obstructed labour. Here a 28-year-old female diagnosed to have a pelvic desmoid, was missed during the antenatal check-up, presented as an obstructed labour which necessitated a caesarean section. The patient underwent a definitive surgery three months later for excision of tumour. The tumour was excised through a combined abdominal and gluteal incision. Histopathological report revealed an aggressive fibromatosis (retroperitoneal desmoid).

Nasal foreign body presenting as unilateral headache

We report a 6 year old female child, who presented with history of right sided recurrent headache for four months. On diagnostic nasal endoscopy, a metallic foreign body was seen impacted between superior turbinate, middle turbinate and nasal septum which was removed using pediatric nasal endoscope. Following removal, the symptom of unilateral headache subsided. Possibility of a foreign body should always be ruled out while evaluating a child with recurrent, unilateral headache.

GRP78 promoter polymorphism rs391957 as potential predictor for clinical outcome in gastric and colorectal cancer patients

BACKGROUND

Recently, the analysis of gastric and colorectal tumor specimens determined that 78-kiloDalton glucose-regulated protein (GRP78), an endoplasmic reticulum chaperone, up-regulation serves as an efficient mechanism protecting cells against apoptosis and can confer drug resistance. We tested whether functional polymorphisms within the GRP78 gene are related to clinical outcome in gastric and colorectal cancer (CRC) patients.

PATIENTS AND METHODS

Blood samples of 234 stage II/III CRC patients at the University of Southern California (USC) and formalin-fixed paraffin-embedded tissues of 137 patients with localized gastric adenocarcinoma (GA) at USC and Memorial Sloan-Kettering Cancer Centers were obtained. GRP78 polymorphisms analyzed on germline DNA were correlated with clinical outcome using univariate and multivariate analyses.

RESULTS

GA patients with the combined GRP78 rs391957 C/T and T/T genotype were at higher risk for tumor recurrence and death [hazard ratio (HR) 2.61; P < 0.001 and HR 3.17; P < 0.001, respectively], than those with C/C. These findings were subsequently tested in a CRC cohort where patients with the homozygous T/T genotype were at highest risk for tumor recurrence (HR 2.61; P = 0.015). The results remained significant after adjusting for clinicopathologic determinants.

CONCLUSION

These data provide the first evidence that the GRP78 rs391957 polymorphism can predict clinical outcome in localized GA and locally advanced CRC patients.
