Abstract
BACKGROUND In response to the high rates of poor mental health in the construction industry, numerous workplace interventions have been designed to address the known and suspected risk factors to employee mental health and well-being. A key challenge of these strategies is low engagement in support services. AIMS The goals of this research were to investigate the help-seeking intentions of employees in the construction industry, explore levels of mental well-being in this population and provide insight into employee engagement with mental health support strategies. METHODS Employees from two UK construction companies completed an online cross-sectional questionnaire (n = 119), designed to measure help-seeking intentions, levels of mental well-being and worker attitudes towards workplace mental health support strategies. RESULTS One-third of the sample reported experiencing an episode of mental health difficulties in the past 6 months. Employees reported a greater preference for seeking support from informal versus formal help sources. Participants were most likely to seek help from a partner and least likely to seek help from a Mental Health First Aider/ Champion. The study also showed some association between help-seeking intention and age of employees. CONCLUSIONS Given the poor levels of mental well-being in this population, it is essential that adequate workplace support is provided. Whilst formal help sources are important for this population, our study highlights the potential benefits of informal help sources to support employees. Future interventions may therefore wish to consider developing tailored, informal workplace support networks and programmes.

Abstract
Quinoline-5,8-diones, also referred to as 5,8-quinolinediones or quinolinequinones, have been researched extensively for their antiproliferative effects, where they displayed great results. Other than anticancer, they exhibit multiple activities such as antimalarial, antiviral, antibacterial, and antifungal activities. Natural quinolinequinones have also been known for their significant activities. The review highlights the diverse biological activities exhibited by synthetic quinoline- 5,8-diones over the past two decades. Continued research in this field is warranted to fully exploit the therapeutic potential of these intriguing compounds and their derivatives for future drug development. By comprehensively evaluating the therapeutic applications and biological activities of quinoline-5,8-dione derivatives, this review endeavors to provide researchers and practitioners with a valuable resource that will foster informed decision-making and inspire further investigations into harnessing the immense potential of this intriguing scaffold for the benefit of human health.

Abstract
The lattice dynamics and high-temperature structural transition in SnS and SnSe are investigated via inelastic neutron scattering, high-resolution Raman spectroscopy and anharmonic first-principles simulations. We uncover a spectacular, extreme softening and reconstruction of an entire manifold of low-energy acoustic and optic branches across a structural transition, reflecting strong directionality in bonding strength and anharmonicity. Further, our results solve a prior controversy by revealing the soft-mode mechanism of the phase transition that impacts thermal transport and thermoelectric efficiency. Our simulations of anharmonic phonon renormalization go beyond low-order perturbation theory and capture these striking effects, showing that the large phonon shifts directly affect the thermal conductivity by altering both the phonon scattering phase space and the group velocities. These results provide a detailed microscopic understanding of phase stability and thermal transport in technologically important materials, providing further insights on ways to control phonon propagation in thermoelectrics, photovoltaics, and other materials requiring thermal management.

Abstract
Background A global rise in multidrug-resistant (MDR) nosocomial infections has led to a significant increase in morbidity and mortality. MDR Gram-negative bacteria (GNB) are recognised for rapidly developing drug resistance. Despite Pseudomonas aeruginosa being the second most common GNB isolated from healthcare associated infections, the magnitude of MDR P. aeruginosa (MDR-PA) has not been evaluated in Qatar. Aim To assess the prevalence and antimicrobial susceptibility patterns of MDR-PA from 5 major hospitals in Qatar. Methods A total of 2533 P. aeruginosa clinical isolates were collected over a one-year period. MDR-PA was defined as resistance to at least one agent of ≥ 3 antibiotic classes. Clinical and demographic data were collected prospectively. Findings The overall prevalence of MDR-PA isolates was 8.1% (205/2533); the majority of isolates were from patients exposed to antibiotics during 90 days prior to isolation (85.4 %, 177/205), and the infections were mainly hospital-acquired (95.1%, 195/205) with only 4.9% from the community. The majority of MDR-PA isolates were resistant to cefepime (96.6%, 198/205), ciprofloxacin, piperacillin/tazobactam (91%, 186/205), and meropenem (90%, 184/205). Patient comorbidities with MDR-PA were diabetes mellitus (47.3%, n=97), malignancy (17.1%, n=35), end-stage renal disease (13.7%, n=28) and heart failure (10.7%, n=22). Conclusion There was a significant prevalence of MDR-PA in Qatar, primarily from healthcare facilities and associated with prior antibiotic treatment. There was an alarming level of antimicrobial resistance to carbapenems. Our results are part of a national surveillance of MDR to establish effective containment plans.

Abstract
Malaria is a major public health concern in Northeast India with a preponderance of drug-resistant strains. Until recently the partner drug for artemisinin combination therapy (ACT) was sulphadoxine pyrimethamine (SP). Antifolate drug resistance has been associated with the mutations at dihydropteroate synthase (dhps) and dihydrofolatereductase (dhfr) genes. This study investigated antifolate drug resistance at the molecular level. A total of 249 fever cases from Arunachal Pradesh, NE India, were screened for malaria, and of these, 75 were found to be positive for Plasmodium falciparum. Samples were sequenced and analysed with the help of BioEdit and ClustalW. Three novel point mutations were found in the dhps gene with 10 haplotypes along with the already reported mutations. A single haplotype having quadruple mutation was found in the dhfr gene. The study reports higher degree of antifolate drug resistance as evidenced by the presence of multiple point mutations in dhps and dhfr genes. The findings of this study strongly discourage the use SP as a partner drug in ACT.

Abstract
Background Little is known about the epidemiological characteristics of papillomavirus (HPV) infection among North African countries. Herein, we conducted a molecular epidemiological study to investigate prevalence of HPV type and HPV-16 variants among cervical-screened unvaccinated Tunisian women. Methods Cross-sectional study was performed on 494 Tunisian women visiting Women’s Healthcare Centers. HPV-DNA detection was carried out on cervical samples using real-time polymerase chain reaction. HPV genotyping and HPV-16 variants were characterized by direct sequencing of L1 viral capsid gene. Results The overall HPV prevalence was 34% (95% CI: 30–38%) with significantly higher prevalence among women with squamous intraepithelial lesions (SIL) than those with no intraepithelial lesions (NIL) 84% (95% CI: 76–92%) and 24.5% (95% CI: 20–29%) respectively. The distribution of HPV prevalence according to women’s age shows a U-shaped curve and the highest HPV prevalence rates were observed among the youngest (≤25 years; 51.2%, 95% CI: 37–67%) and the oldest women (>55 years; 41.7%, 95% The HPV-16 prevalence was 32.8% (95% CI: 22–45%) among women with SIL and 9.2% (95% CI: 6–12%) among women with NIL. Whereas, the HPV-18 prevalence was 1.3% (95% CI: 0–5%) among women with SIL and 0.3% (95% CI: 0–1%) among women with NIL. Among HPV-16 positive women, European lineage (E) was identified as the predominant HPV-16 variant (85.7%, 95% CI: 76–95%). The frequency of E variant was lower among SIL than among NIL women (81%, 95% CI: 64–99%, and 88%, 95% CI: 77–100%, respectively). Conversely, the African-2 variant frequency was higher among SIL than among NIL women (18%, 95% CI: 1–36% and 6%, 95% CI: 2–14%, respectively). In multivariate analysis, young age was the only risk factor that is independently associated with HPV infection. Moreover, HPV infection and menopause were both found to be independently associated with SIL and HSIL. Conclusion HPV DNA testing should be proposed to young and menopausal Tunisian women. Considering HPV prevalence, only 13% of the Tunisian women could be protected by the bivalent HPV vaccine. These results may be helpful for designing an adapted HPV testing and vaccination program in Tunisia.

Abstract
OBJECTIVE The aim of the study was to evaluate the impact of traumatic lumbar puncture (TLP) at diagnosis of relapse in childhood acute lymphoblastic leukemia (ALL). Risk factors associated with TLP were assessed. MATERIALS AND METHODS A retrospective analysis was performed from the records of children with ALL who were treated from January 2010 to December 2012. RESULTS A total of 311 patients with median age of 5 years (range: 1-13) were treated for ALL. The cerebrospinal fluid analysis obtained from first LP revealed 275: Central nervous system 1 (CNS 1) (no blasts); 8: CNS 3 (blasts positive); and 28: TLP. Twenty-eight (9%) patients relapsed. Twelve (3.9%) had a CNS relapse. A TLP at diagnosis was not associated with an increased risk of systemic or CNS relapse (P = 0.298, 0.295). Three years event-free survival of patients with TLP and without atraumatic LP (ATLP) at diagnosis was 56 ± 5.2% and 51.8 ± 12.4%, (P = 0.520). Three years overall survival with TLP and ATLP was 73.3 ± 3.5% and 70.4 ± 12.5%, respectively, (P = 0.963). Median platelet count in patients with TLP was significantly lower than those without TLP (10,000/μL and 28,000/μL, P < 0.001). A receiver operating characteristic curve was constructed for predicting the risk of TLP based on platelet count. Area under the curve was 0.74 ± 0.05 (95% confidence interval 0.64-0.84). Platelet count < 23.5 × 109/L at the time of LP had 75% sensitivity and 64.4% specificity in predicting a TLP. CONCLUSIONS Low platelet counts are significantly associated with risk of TLP. Traumatic LP at diagnosis was not associated with an increased risk of relapse.

Abstract
A wide range of genital infections and skin conditions may present with vulval pruritus. Lichen sclerosus is one cause. This is often associated with visible skin changes which include atrophy, resorption or fusion of the labia, sclerosis and excoriation. Ulceration may indicate malignant transformation and requires urgent biopsy. Many experienced clinicians diagnose lichen sclerosus on clinical appearance, however we recommend a low threshold for biopsy, especially for non-responding or odd looking lesions. We report a patient whose vulval skin biopsy for clinically suspected lichen sclerosus revealed extramammary Paget's disease of the vulva. We review the pathology, prognosis and treatment of this condition.

Abstract
The optimal end-tidal sevoflurane concentration for successful ProSealTM (Teleflex, Morrisville, NC, USA) laryngeal mask airway (PLMA) versus ClassicTM (Teleflex, Morrisville, NC, USA) laryngeal mask airway (CLMA) insertion in unpremedicated anaesthetised adults is unknown. We determined end-tidal sevoflurane concentrations for successful insertion in fifty percent of anaesthetised adults. This randomised, prospective, double-blind study was conducted in the operating theatre of a government tertiary care hospital. Forty-four unpremedicated American Society of Anesthesiologists physical status I and II women with cervical carcinoma (aged 30 to 60 years), scheduled for intracavity caesium implantation under general anaesthesia with a laryngeal mask airway (LMA) were included in the study. The participants were randomised to one of the two groups, to receive either a PLMA or CLMA. After anaesthetic induction with sevoflurane, a predetermined end-tidal sevoflurane concentration (starting at 2.5%) was sustained for 10 minutes before LMA insertion was attempted. End-tidal sevoflurane concentration was increased/decreased (step-size 0.25%) using Dixon and Massey's up-and-down method for the next patient based on the previous patient's response. Placement without clenching, movement, coughing or biting within one minute was considered successful insertion. The end-tidal sevoflurane concentration required for successful LMA insertion in fifty percent of anaesthetised adults was calculated as the mean of the crossover pairs' midpoints in each group and further confirmed by probit regression analysis. The end-tidal sevoflurane concentration (95% confidence interval) required for successful PLMA insertion in 50% of anaesthetised adults (3.15% [3.12% to 3.18%]) was significantly higher than that for CLMA insertion (2.71% [2.66% to 2.76%], P<0.001). These findings suggest that deeper anaesthesia is required for placement of a PLMA in comparison to a CLMA.

Abstract
BACKGROUND Undernutrition is considered to have a negative impact on survival in children with malignancies. The objective of this retrospective analysis was to evaluate the morbidity pattern and outcome of therapy in undernourished (UN) children with acute lymphoblastic leukemia. METHODS A retrospective analysis of impact of weight for age was performed in children treated for ALL. The IAP & CDC criteria for undernutrition were used in the two different time periods of analysis. RESULTS There were two cohorts in the study: Between 1995 and 2005, 360 children were evaluated where the weight for age was classified using the Indian Academy of Pediatrics criteria for undernourishment (Group A). Group B of the study included 373 children treated from 2007 to 2011, who were graded as per the Centers for Disease Control criteria for weight for age. In Group A, 35% of the children were malnourished at presentation. The morbidity and supportive care needed in the well-nourished and UN group were similar. The event-free survival and mortality were similar in both groups. Analysis of Group B showed an overall survival of 62.6% with a greater survival in children with a weight of ≥10th centile for age compared to children at the <10th centile, (P = 0.026) with a higher mortality (P = 0.011) in the UN group. CONCLUSION Our data have yielded conflicting results. The older cohort did not show a significant difference in survival using malnutrition as a risk factor. However, in the subsequent cohort, a difference in survival was noted. This could be due to the reason that different criteria for classification of undernutrition were applied in the two groups. This analysis lays the foundation for a future prospective analysis to evaluate nutrition as an independent risk factor nutrition as an independent risk factor in the outcome of childhood malignancies.

Abstract
Gene targeting and overexpression studies have demonstrated the importance of the clustered homeobox (HOX) genes in hematopoesis. In addition, global HOX gene dysregulation is found in the majority of cases of acute myeloid leukemia (AML) and many cases of acute lymphoblastic leukemia (ALL), and substantial evidence exists to suggest that aberrant expression of HOX genes contributes to the pathogenesis of leukemia. However, although individual HOX genes are rearranged in rare cases of AML and HOX genes are known transcriptional targets of certain leukemia-associated fusion proteins, such as those involving the mixed lineage leukemia (MLL) gene, in the majority of cases, the upstream regulators of HOX genes are unknown. The CDX family of non-clustered homeobox genes are known developmental regulators of HOX gene expression. We have recently demonstrated that Cdx4 is expressed in adult murine bone marrow where its expression pattern follows that of Hox genes. We also demonstrated that CDX2 is expressed in the majority, and that CDX4 is expressed in almost a quarter, of AML patient samples. For CDX2, this expression was predominantly monoallelic but was not associated with coding sequence or promoter mutations, gene amplification, or aberrant promoter methylation. In addition, stable knockdown of CDX2 resulted in a loss of proliferation and clonogenicity in AML cell lines, and bone marrow retrovirally engineered to express either Cdx2 or Cdx4 generated AML in transplant recipients. Cdx4 was shown to cooperate with the known Hox cofactor Meis1a, and structure-function experiments confirmed that the transcription factor function of Cdx4 was required for transformation. Finally, expression of either Cdx2 or Cdx4 generated a dysregulated Hox gene program in normal hematopoietic progenitors and in leukemic tissue. Taken together, these studies implicate CDX proteins as master regulators of HOX gene regulation in AML.

Abstract
OBJECTIVE To assess the feasibility and outcomes of laparo-endoscopic single site (LESS) partial nephrectomy (PN) in infants and small children for upper urinary tract duplication anomalies. MATERIALS AND METHODS The medical records of all patients undergoing LESS PN at a single pediatric institution were retrospectively reviewed for patient demographics, perioperative details, and outcomes. A cystoscopy was initially performed to place an externalized catheter into the ureter of the ipsilateral normal renal moiety. An Olympus TriPort, an Olympus Endoeye flexible tip laparoscope, standard 3- or 5-mm instrumentation, and a LigaSure Blunt were utilized. RESULTS Four children (two boys, two girls) underwent LESS PN. Three patients underwent upper pole PN and one underwent lower pole PN. All procedures were performed for poorly functioning obstructed renal moieties (one ureterocele, one ureteropelvic junction obstruction and vesicoureteral reflux, and two ectopic ureters). Median age was 6.2 months (range 2.5-16.4 months). Median weight was 7.7 kg (range 6.1-12.6 kg). Median operative time was 126 min (range 97-180 min). No patient received inpatient postoperative narcotics. Median follow-up was 9.9 months (range 6.2-19.1 months). No postoperative complications were noted. Postoperative renal ultrasound demonstrated successful resection in all patients. CONCLUSIONS LESS PN is technically feasible, safe, and effective for upper urinary tract duplication anomalies in infants and small children.

Abstract
BACKGROUND Multidrug resistant (MDR) pathogens are becoming a major problem worldwide, more so in the immunocompromised hosts resulting in the urgent need of antibiotic stewardship. PURPOSE To analyze the organisms isolated and the drug resistance pattern in a pediatric oncology unit. RESULTS Data pertaining to infections with 128 positive cultures in patients with febrile neutropenia over a period of 1-year are presented. The unit antibiotic policy is decided depending on the sensitivity of the prevailing common organisms. We isolated Gram-negative organisms in 56% cases. Escherichia coli and Klebseilla were the most frequent lactose fermenting Gram-negative Bacilli and Pseudomonas and Acinetobacter the nonfermenting Gram-negative Bacilli. Only 20-30% of the Gram-negative organisms cultured were sensitive to a 3rd/4th generation cephalosporin. The combination of a beta-lactam/inhibitor covered 2/3rd of Gram-negative organisms. About 80% of the organisms were sensitive to carbapenems. There was no colistin resistance. About 44% of our cultures grew a Gram-positive bacterial organism and included coagulase negative Staphylococcus. We had an incidence of methicillin resistant Staphylococcus aureus to be 30%. About 30% of the enterococci isolated in our unit were vancomycin-resistant enterococci. About 23% of patients with a positive bacterial culture died. CONCLUSIONS Infections in pediatric cancer patient's account for about 15-20% of the deaths in developing countries as these patients are at a high risk for developing MDR infections. Resistance rates among Gram-positive and Gram-negative organisms have increased worldwide. Every unit needs a rational antibiotic policy. Antibiotic de-escalation and judicious decrease in the duration of antibiotics needs to be practiced.

Abstract
INTRODUCTION The potential impact of concomitant iron deficiency on hemoglobin A2 (HbA2)-based identification of β-thalassemia trait (βTT) is a worrisome issue for screening laboratories. This is especially true for resource-constrained settings where iron deficiency is widespread and molecular confirmatory tests for borderline low HbA2 values may be unavailable. METHODS Obligate βTT carrier individuals (n = 752) were identified during screening studies on the parents of thalassemia major patients. HbA2%, complete blood counts and serum iron, ferritin and transferrin saturation were studied. Iron-deficient individuals (n = 135) with normal range HbA2% were taken as controls. RESULTS Concomitant iron deficiency (defined as ferritin ≤15 ng/mL and/or transferrin saturation ≤15%) was present in 20.7% (156/752) βTT cases, that is, 33.3% females (122/366) and 8.8% males with βTT (34/386). Mean HbA2 in iron-replete βTT was 5.4 ± 0.8 (range 3.1-7.9) and in iron-deficient βTT was 5.4 ± 0.9 (range 3.3-7.6). HbA2 < 4.0% was found in 23/752 (3.1%) βTT: 13/595 iron-replete (2.2%) and 10/157 (6.4%) iron-deficient βTT individuals. However, five of the 10 iron-deficient βTT cases carried the silent CAP+1 (A>C) β-thalassemia allele accounting for the borderline HbA2%. On a separate analysis, all five severely anemic βTT (Hb < 80 g/L) and 16/17 βTT with severe hypoferritinemia (<5 ng/mL) had HbA2 > 4.5%. The single case with serum ferritin 4.8 ng/mL and HbA2 3.3% showed a CAP+1 (A>C) mutation. CONCLUSIONS Iron deficiency was prevalent among north Indian βTT individuals, especially women. After adjusting for other causes of low HbA2 in βTT, iron deficiency, even when very severe, was very unlikely to interfere significantly with HbA2-based identification of βTT.

Abstract
OBJECTIVE To present our experience with infant pyeloplasty, comparing outcomes between robotic-assisted laparoscopic pyeloplasty (RALP) and open pyeloplasty (OP). MATERIALS AND METHODS A retrospective review was performed of all children <1 year of age who underwent unilateral dismembered pyeloplasty at a single pediatric institution since January 2007. Patients with standard laparoscopic pyeloplasty were excluded. Patient demographics, intraoperative details, narcotic usage, and complications were reviewed. RESULTS A total of 70 infants (51 boys and 19 girls) were identified, with nine RALP and 61 OP performed. Median age was 9.2 months (range, 3.7-11.9 months) for RALP and 4.1 months (range, 1.0-11.6 months) for OP (p = 0.005). Median weight was 8 kg (range, 5.8-10.9 kg) for RALP and 7 kg (range, 4-14 kg) for OP (p = 0.163). Median operative time was 115 min (range, 95-205 min) for RALP and 166 min (range, 79-300 min) for OP (p = 0.028). Median hospital stay was 1 day (range, 1-2 days) for RALP and 3 days (range, 1-7 days) for OP (p < 0.001). Median postoperative narcotic use of morphine equivalent was <0.01 mg/kg/day (range, 0-0.1 mg/kg/day) for RALP and 0.05 mg/kg/day (range, 0-2.2 mg/kg/day) for OP (p < 0.001). Median follow-up was 10 months (range, 7.2-17.8 months) for RALP and 43.6 months (3.4-73.8 months) for OP (p < 0.001). The success rate was 100% for RALP and 98% for OP. CONCLUSIONS Infant RALP was observed to be feasible and efficacious with shorter operative time, hospital stay, and narcotic utilization than OP.

Abstract
To examine the efficacy, safety and tolerability of tolterodine in children with overactive bladder in comparison with standard treatment i.e. oxybutynin as demonstrated in randomized clinical trials and other studies. A systematic search was done to screen the studies evaluating the effect of tolterodine in children with non-neurogenic overactive bladder. Results of studies were pooled and compared. Efficacy was determined from micturition diaries and dysfunctional voiding symptoms score. Safety and tolerability were assessed from the reported treatment emergent adverse events. A total of six randomized clinical trials and 11 other studies of tolterodine in children with urinary incontinence were included in the present systematic review. The dose of tolterodine used in different settings ranged from '0.5 to 8 mg/day' instead of '0.5 to 8 mg/kg per day' and the duration of studies ranged from 2 weeks to 12 months. Both extended and immediate release preparations of tolterodine were shown to have comparable efficacy and tolterodine proved to have comparable efficacy with better tolerability than oxybutynin in these studies. It can be concluded that tolterodine is efficacious in treatment of urinary incontinence in children. Moreover, its efficacy is comparable to oxybutynin, the most commonly prescribed anticholinergic in this condition, while having better tolerability. Hence, it can be considered as first line therapy for the treatmentof urinary incontinence in children.

Abstract
BACKGROUND Emerging evidence suggests that diabetes may increase the risk of cancers. However, available evidence on prostate cancer is conflicting. We therefore examined the association between Type 2 diabetes and risk of prostate cancer by conducting a detailed meta-analysis of all studies published regarding this subject. METHODS PubMed database and bibliographies of retrieved articles were searched for epidemiological studies (published between 1970 and 2011), investigating the relationship between Type 2 diabetes and prostate cancer. Pooled risk ratio (RR) was calculated using random-effects model. Subgroup, sensitivity analysis and cumulative meta-analysis were also done. RESULTS Forty-five studies (29 cohort and 16 case-control studies) involving 8.1 million participants and 132 331 prostate cancer cases detected a significant inverse association between Type 2 diabetes and risk of prostate cancer (RR 0.86, 95% confidence interval (CI) 0.80-0.92). For cohort studies alone, the RR was 0.87 (95% CI 0.80-0.94), and for case-control studies alone, the RR was 0.85 (95% CI 0.74-0.96). Sensitivity analysis done by excluding one outlier further strengthened our negative association (RR 0.83, 95% CI 0.78-0.87). No evidence of publication bias was observed. CONCLUSIONS This meta-analysis provides strongest evidence supporting that Type 2 diabetes is significantly inversely associated with risk of developing prostate cancer.

Abstract
Background Mutations in the genes coding for either dystrophin or dysferlin cause distinct forms of muscular dystrophy. Dystrophin links the cytoskeleton to the sarcolemma through direct interaction with β-dystroglycan. This link extends to the extracellular matrix by β-dystroglycan's interaction with α-dystroglycan, which binds extracellular matrix proteins, including laminin α2, agrin and perlecan, that possess laminin globular domains. The absence of dystrophin disrupts this link, leading to compromised muscle sarcolemmal integrity. Dysferlin, on the other hand, plays an important role in the Ca2+-dependent membrane repair of damaged sarcolemma in skeletal muscle. Because dysferlin and dystrophin play different roles in maintaining muscle cell integrity, we hypothesized that disrupting sarcolemmal integrity with dystrophin deficiency would exacerbate the pathology in dysferlin-null mice and allow further characterization of the role of dysferlin in skeletal muscle. Methods To test our hypothesis, we generated dystrophin/dysferlin double-knockout (DKO) mice by breeding mdx mice with dysferlin-null mice and analyzed the effects of a combined deficiency of dysferlin and dystrophin on muscle pathology and sarcolemmal integrity. Results The DKO mice exhibited more severe muscle pathology than either mdx mice or dysferlin-null mice, and, importantly, the onset of the muscle pathology occurred much earlier than it did in dysferlin-deficient mice. The DKO mice showed muscle pathology of various skeletal muscles, including the mandible muscles, as well as a greater number of regenerating muscle fibers, higher serum creatine kinase levels and elevated Evans blue dye uptake into skeletal muscles. Lengthening contractions caused similar force deficits, regardless of dysferlin expression. However, the rate of force recovery within 45 minutes following lengthening contractions was hampered in DKO muscles compared to mdx muscles or dysferlin-null muscles, suggesting that dysferlin is required for the initial recovery from lengthening contraction-induced muscle injury of the dystrophin-glycoprotein complex-compromised muscles. Conclusions The results of our study suggest that dysferlin-mediated membrane repair helps to limit the dystrophic changes in dystrophin-deficient skeletal muscle. Dystrophin deficiency unmasks the function of dysferlin in membrane repair during lengthening contractions. Dystrophin/dysferlin-deficient mice provide a very useful model with which to evaluate the effectiveness of therapies designed to treat dysferlin deficiency.

Abstract
Biomarkers derived from gene expression profiling data may have a high false-positive rate and must be rigorously validated using independent clinical data sets, which are not always available. Although animal model systems could provide alternative data sets to formulate hypotheses and limit the number of signatures to be tested in clinical samples, the predictive power of such an approach is not yet proven. The present study aims to analyze the molecular signatures of liver cancer in a c-MET-transgenic mouse model and investigate its prognostic relevance to human hepatocellular carcinoma (HCC). Tissue samples were obtained from tumor (TU), adjacent non-tumor (AN) and distant normal (DN) liver in Tet-operator regulated (TRE) human c-MET transgenic mice (n = 21) as well as from a Chinese cohort of 272 HBV- and 9 HCV-associated HCC patients. Whole genome microarray expression profiling was conducted in Affymetrix gene expression chips, and prognostic significances of gene expression signatures were evaluated across the two species. Our data revealed parallels between mouse and human liver tumors, including down-regulation of metabolic pathways and up-regulation of cell cycle processes. The mouse tumors were most similar to a subset of patient samples characterized by activation of the Wnt pathway, but distinctive in the p53 pathway signals. Of potential clinical utility, we identified a set of genes that were down regulated in both mouse tumors and human HCC having significant predictive power on overall and disease-free survival, which were highly enriched for metabolic functions. In conclusions, this study provides evidence that a disease model can serve as a possible platform for generating hypotheses to be tested in human tissues and highlights an efficient method for generating biomarker signatures before extensive clinical trials have been initiated.

Abstract
Haemophilus influenzae is a major public health concern in the developing world. The most virulent strain is H. influenzae Type b (Hib). Hib also constitutes a major portion of nasopharyngeal commensal flora in otherwise healthy individuals. Through dendogram based on composite gene sequences of seven multi locus sequence type genes, it was observed that invasive and commensal isolates made two completely separate clusters which are indicative of independent evolution of these two groups of H. influenzae in the Indian subcontinent.

Abstract
Mutations in the dysferlin gene underlie a group of autosomal recessive muscle-wasting disorders denoted as dysferlinopathies. Dysferlin has been shown to play roles in muscle membrane repair and muscle regeneration, both of which require vesicle-membrane fusion. However, the mechanism by which muscle becomes dystrophic in these disorders remains poorly understood. Although muscle inflammation is widely recognized in dysferlinopathy and dysferlin is expressed in immune cells, the contribution of the immune system to the pathology of dysferlinopathy remains to be fully explored. Here, we show that the complement system plays an important role in muscle pathology in dysferlinopathy. Dysferlin deficiency led to increased expression of complement factors in muscle, while muscle-specific transgenic expression of dysferlin normalized the expression of complement factors and eliminated the dystrophic phenotype present in dysferlin-null mice. Furthermore, genetic disruption of the central component (C3) of the complement system ameliorated muscle pathology in dysferlin-deficient mice but had no significant beneficial effect in a genetically distinct model of muscular dystrophy, mdx mice. These results demonstrate that complement-mediated muscle injury is central to the pathogenesis of dysferlinopathy and suggest that targeting the complement system might serve as a therapeutic approach for this disease.

Abstract
BACKGROUND Relapse of disease is documented in 15-20% of children with acute lymphoblastic leukemia (ALL). Although testicular relapse is rare with modern risk-adapted treatment protocols, earlier, the testes were a frequently encountered site of relapse and were designated as "drug sanctuaries". PURPOSE This descriptive study was designed to assess the pattern of testicular relapse and to identify high-risk factors. MATERIALS AND METHODS Data obtained from case records of 407 boys with ALL were analyzed. Fine needle aspiration cytology was carried out in children presenting with painless enlargement of testi(e)s. Bone marrow aspiration and cerebrospinal fluid examination were performed concomitantly to confirm or exclude disease at these sites. RESULTS Testicular relapse was documented in 30 boys. It was isolated in 17 patients and associated with bone marrow and/or central nervous system relapse in 13. At relapse, nine boys were over the age of 10 years. The majority were very early and early relapsers. Hyperleucocytosis was documented in five of 30 and seven of 137 relapsers and nonrelapsers, respectively (P = 0.04). Twelve of the 30 boys with testicular relapse were treated with testicular irradiation, reinduction and maintenance therapy. The estimated median overall survival was 33 months. CONCLUSION Testicular relapse, which depends on the therapy administered, may manifest several months/years after completion of treatment. The high incidence of testicular relapse in our series implicates the need of revaluation of our protocol and incorporation of high/intermediate dose methotrexate therapy upfront.

Abstract
OBJECTIVE To analyze the prognostic impact of overt testicular disease (OTD) at diagnosis and role of testicular irradiation in the same. METHODS Data of 579 boys treated at our center over 16 years was reviewed. RESULTS Fourteen (2.4%) males had OTD. 10 (71.4%) of these had high-risk disease. Patients with OTD, had a significantly higher incidence of mediastinal-adenopathy (p=0.001), hyperleucocytosis (p=0.004) and CNS disease at presentation (p<0.0001) compared to patients in continuous complete remission (CCR). 4 of the 11 patients with OTD, who opted for therapy, had relapse; 2 are in CCR. Although, survival in patients with OTD was inferior (p=0.183) compared to patients without OTD, it was not an independent prognostic factor (p=0.47). In the entire study cohort, symptom-diagnosis interval (p=0.006), white cell (p=0.001) and platelet count (p=0.001) at presentation were significantly associated with survival (Cox multivariate regression analysis). CONCLUSIONS OTD was not an independent prognostic factor, despite association with high-risk features. Survival outcome was inferior. The observations indicate the need of revaluation of the present protocol with incorporation of intermediate dose and subsequently high-dose methotrexate (after assessment for toxicity and tolerance), risk-stratified therapy and plausibly omission of testicular irradiation.

Abstract
BACKGROUND Cdx4 is a homeobox gene essential for normal blood formation during embryonic development in the zebrafish, through activation of posterior Hox genes. However, its role in adult mammalian hematopoiesis has not been extensively studied and its requirement in leukemia associated with Hox gene expression alteration is unclear. DESIGN AND METHODS We inactivated Cdx4 in mice through either a germline or conditional knockout approach and analyzed requirement for Cdx4 in both normal adult hematopoiesis and leukemogenesis initiated by the MLL-AF9 fusion oncogene. RESULTS Here, we report that loss of Cdx4 had a minimal effect on adult hematopoiesis. Indeed, although an increase in white blood cell counts was observed, no significant differences in the distribution of mature blood cells, progenitors or stem cells were observed in Cdx4-deficient animals. In addition, long-term repopulating activity in competitive transplantation assays was not significantly altered. In vitro, B-cell progenitor clonogenic potential was reduced in Cdx4-deficient animals but no significant alteration of mature B cells was detected in vivo. Finally, induction of acute myeloid leukemia in mice by MLL-AF9 was significantly delayed in the absence of Cdx4 in a retroviral transduction/bone marrow transplant model. CONCLUSIONS These observations indicate that Cdx4 is dispensable for the establishment and maintenance of normal hematopoiesis in adult mammals. These results, therefore, outline substantial differences in the Cdx-Hox axis between mammals and zebrafish and support the hypothesis that Cdx factors are functionally redundant during mammalian hematopoietic development under homeostatic conditions. In addition, our results suggest that Cdx4 participates in MLL-AF9-mediated leukemogenesis supporting a role for Cdx factors in the pathogenesis of myeloid leukemia.

Abstract
AIMS To compare the efficacy and safety of pregabalin and amitriptyline in alleviating pain associated with diabetic peripheral neuropathy. METHODS A randomized, double-blind, crossover, active-control, clinical trial with variable dose titration was carried out (n = 51). Amitriptyline orally, at doses of 10, 25 and 50 mg at night-time and pregabalin orally, at doses of 75, 150 and 300 mg twice daily, by optional titration was used. Each drug treatment was of 5 weeks. There was a placebo washout period for 3 weeks between the two drugs. Assessment for pain relief, overall improvement and adverse events were carried out. RESULTS Good, moderate and mild pain relief were noted in 21 (48%), 6 (13%) and 7 (15%) patients on pregabalin and 15 (34%), 5 (11%) and 12 (27%) patients on amitriptyline, respectively, by patient's global assessment of efficacy and safety. Patient and physician's global assessment, McGill pain questionnaire, Likert pain scale and Patient Global Impression of Change showed no significant difference between the treatments, although improvement with both treatments was seen from the first week. Of the 52 adverse events reported, 34 (65.4%) were with amitriptyline, drowsiness being the commonest [in 19 (43%) patients]. Pregabalin caused adverse events in 18 (25%), of which drowsiness was the most common in nine (20%) patients. The preferred pregabalin dose was 150 mg twice daily. CONCLUSIONS As there are few differences between the two treatments in efficacy, pregabalin 150 mg twice daily might be the alternative choice as it is associated with fewer adverse effects in our population.
