Abstract
BACKGROUND Key challenges in paediatric TB diagnosis are invasive sampling and poor sensitivity of standard methods. This study demonstrates the diagnostic potential of non-invasive sampling of bioaerosols from children using SMaRT-PCR, comprising mask sampling combined with reverse transcriptase-polymerase chain reaction (RT-PCR) for TB.METHODS Exhaled bioaerosols were captured on modified N-95 masks in a 10-min talk-cough-breathe process from 51 children (30 with TB confirmed using standard sampling methods and 21 without TB) aged 2-15 years. All mask samples were tested using in-house RT-PCR for 16s and rpoB RNA transcripts. Additional mask samples from children with TB were tested using Xpert® MTB/RIF (n = 3) and Xpert® MTB/RIF Ultra (n = 27).RESULTS SMaRT-PCR sensitivity for detecting TB among treatment-naïve children was 96% if 16s or rpoB was present, and 75% if both genes were present, comparable to standard methods (71%) in the same cohort. Specificity was better for both genes, at 95%, than 85% for a single gene detection. Mask sampling with Xpert MTB/RIF or Ultra had a sensitivity of only 13%.CONCLUSION This is the first study to provide evidence for testing bioaerosols as a promising alternative for detecting paediatric TB. Sampling is non-invasive and simple, with the potential for point-of-care applications. This pilot study also suggests that RNA transcript-based detection may improve TB diagnostic sensitivity in children; however, further investigation is required to establish its adaptability in clinical settings..

Abstract
In the present study, we isolated a potent endophytic fungus from the roots of Withania somnifera. The endophytic fungal strain was authenticated as Penicillium ramusculum SVWS3 based on morphological and molecular sequencing using four gene data and phylogenetic analyses. In vitro cytotoxicity studies unveiled the remarkable cytotoxic potential of the crude extract derived from P. ramusculum, exhibiting dose-dependent effects on MDA-MB-468 and MCF-7 cells. At a concentration of 100 µg/mL, the crude extract resulted in cell viability of 29.78% for MDA-MB-468 cells and 14.61% for MCF-7 cells. The IC50 values were calculated as 62.83 ± 0.93 µg/mL and 17.23 ± 1.43 µg/mL, respectively for MDA-MB-468 and MCF-7 cells. Caspase activation assay established the underlying mechanism of the crude extract depicting the activation of caspases 3 and 7, indicating the induction of apoptosis in MCF-7 cells. Chemotaxonomic profiling elucidated the ability of P. ramusculum to synthesize a diverse array of bioactive compounds, including Fasoracetam, Tryprostatin B, Odorinol, Thyronine, Brevianamide F, Proglumide, Perlolyrine, Tyrphostin B48, Baptifoline, etc. Molecular docking studies inferred that Baptifoline, Brevianamide F, Odorinol, Perlolyrine, Thyronine, Tryphostin B48, and Tryprostatin B were the lead compounds that could effectively interact with the five selected target receptors of breast cancer, further surpassing the positive controls analyzed. Pharmacokinetic profiling revealed that Baptifoline, Odorinol, and Thyronine depicted an excellent therapeutic profile of druggability. These findings collectively substantiate the anticancer activity of bioactive metabolites synthesized by P. ramusculum SVWS3. Hence, the endophytic P. ramusculum SVWS3 can be an authentic source for developing novel chemotherapeutic drug formulations.

Abstract
The non-specificity of standard anticancer therapies has profound detrimental consequences in clinical treatment. Therapeutic specificity can be precisely achieved using cutting-edge ligands. Small synthetic oligonucleotide-ligands chosen through Systematic evolution of ligands by exponential enrichment (SELEX) would be an unceasing innovation in using nucleic acids as aptamers, frequently referred to as "chemical antibodies." Aptamers act as externally controlled switching materials that can attach to various substrates, for example, membrane proteins or nucleic acid structures. Aptamers pose excellent specificity and affinity for target molecules and can be used as medicines to suppress tumor cell growth directly. The creation of aptamer-conjugated nanoconstructs has recently opened up innovative options in cancer therapy that are more effective and target tumor cells with minor toxicity to healthy tissues. This review focuses on a comprehensive description of the most capable classes of aptamer-tethered nanocarriers for precise recognition of cancer cells with significant development in proficiency, selectivity, and targetability for cancer therapy. Existing theranostic applications with the problems and future directions are also highlighted.

Abstract
Autoimmune thyroid disease (AITD) is a common organ-specific autoimmune disease. A strong influence of genetic and epigenetic modifications has been demonstrated to take part in the development and progression of autoimmune thyroid diseases. The linkage between the Vitamin D receptor (VDR) polymorphism and several autoimmune disorders, including the AITD. In this article, we aim to investigate the Frequency of VDR Fokl (rs2228570) genotypes (CC, CT, TT) and alleles (C,T) in autoimmune thyroiditis. The investigation of VDR Fokl (rs2228570) was conducted on 150 samples (control (75 healthy women) and diseased women (75 diseased with autoimmune thyroiditis)) patients from the Adjara (Georgia) Population. It also examined some clinical and laboratory characteristics of the study population. Autoimmune thyroiditis's disease was diagnosed by measuring blood antibodies, determining the level of thyroperoxidase, and conducting an ultrasound examination. Anti-TPO and TSH were studied using the ELISA method. The genomic DNA was extracted from the peripheral blood. The polymerase chain reaction was evaluated to examine the VDR Fokl rs2228570 SNP polymorphism. According to VDR Fokl (rs2228570) genotypes (CC; CT, TT) frequency, in the control group, the Frequency of CC-genotype is 48%, CT-heterozygous genotype is 29.33%, and TT-genotype is 22.67%; in the diseased population, the Frequency of CC-genotype is 57.33%, CT-genotype is 34.67%, and TT-genotype is 8%. According to VDR Fokl (rs2228570) alleles (C, T), the Frequency of the C-allele is high, and the Frequency of the T-allele is low in both populations. The Frequency of the CC and CT genotypes of VDR Fokl (rs2228570) is high in the population with autoimmune thyroiditis compared to the control group; the TT genotype is relatively low in the population suffering from autoimmune thyroiditis; According to VDR Fokl (rs2228570) alleles (C, T), the Frequency of C-allele is high both population.

Abstract
High Risk Human Papilloma Viruses (HR-HPV) persistently infect women with Human Immunodeficiency Virus-1 (HIV-1). HPV-16 escapes immune surveillance in HIV-1 positive women receiving combined antiretroviral therapy (cART). HIV-1 Tat and HPV E6/E7 proteins exploit Notch signaling. Notch-1, a developmentally conserved protein, influences cell fate from birth to death. Notch-1 and its downstream targets, Hes-1 and Hey-1 contribute to invasive and aggressive cancers. Cervical cancer cells utilize Notch-1 and hyper-express CXCR4, a co-receptor of HIV-1. Accumulating evidence shows that HIV-1 affects cell cycle progression in pre-existing HPV infection. Additionally, Tat binds Notch-1 receptor for activation and influences cell proliferation. Oncogenic viruses may interfere or converge together to favor tumor growth. The molecular dialogue during HIV-1/HPV-16+ co-infections in the context of Notch-1 signaling has not been explored thus far. This in vitro study was designed with cell lines (HPV-ve C33A and HPV-16+ CaSki) which were transfected with plasmids (pLEGFPN1 encoding HIV-1 Tat and pNL4-3 encoding HIV-1 [full HIV-1 genome]). HIV-1 Tat and HIV-1 inhibited Notch-1expression, with differential effects on EGFR. Notch-1 inhibition nullified Cyclin D expression with p21 induction and increased G2-M cell population in CaSki cells. On the contrary, HIV-1 infection shuts down p21 expression through interaction of Notch-1 downstream genes Hes-1-EGFR and Cyclin D for G2-M arrest, DDR response and cancer progression. This work lays foundations for future research and interventions, and therefore is necessary. Our results describe for the first time how HIV-1 Tat cancers have an aggressive nature due to the interplay between Notch-1 and EGFR signaling. Notch-1 inhibitor, DAPT used in organ cancer treatment may help rescue HIV-1 induced cancers. Graphical abstract The illustration shows how HIV interacts with HPV-16 to induce Notch 1 suppression for cancer progression (Created with BioRender.com).

Abstract
INTRODUCTION To compare robotic assisted radical prostatectomy (RARP) in well-selected older patients with clinically localized prostate cancer, compared to a younger population. Primary endpoint was perioperative outcomes comparison and secondary endpoint were oncological and functional outcomes comparison to a younger population. METHODS Single tertiary center cohort of consecutive patients treated with RARP (2017-2020) with retrospective analysis. Patients were classified by age in two groups: <75: control group (CG) and ≥75: study group (SG). Patients aged ≥75 had a comprehensive geriatric assessment (CGA) and only patients classified Balducci ≤2 were admitted to surgery. RESULTS Two hundred and sixty-nine patients were included, 56 in SG and 213 in CG. Median follow-up was 9.8 months. Univariate analysis showed no statistically significant (SS) difference between the groups for patients' characteristics (PSA, digital rectal examination -DRE- and biopsy Gleason Score), perioperative data (operative time, hospitalization length, transfusions rate, immediate complications, Clavien-Dindo complications, 30-days re-interventions and 30-days re-hospitalisation), oncological (TNM, margins, extraprostatic extension, postoperative PSA, BCR, metastases, overall survival -OS- and cancer specific survival -CSS-) and functional outcomes. Median perioperative blood loss was lower in the SG: 200.00 cc IQR [100.00, 300.00] vs 200.00cc IQR [100.00, 400.00] in the CG (P<0.05). A multivariate regression considering age>75, DRE, GS, PSA, cardiovascular history and diabetes showed none of variables associated with early BCR. Limitations are retrospective design, small number of patients and short follow-up. CONCLUSIONS RARP shows similar perioperative, oncologic and functional outcomes for older patients selected by a CGA when compared to younger patients. The SG shows a minor perioperative bleeding. LEVEL OF EVIDENCE IV.

Abstract
Dendrimers have been comprehensively used for cargo delivery, nucleic acid delivery (genes, miRNA/siRNAs), delivery of macromolecules, and other various biomedical applications. Dendrimers are highly versatile in function and can be engineered as multifunctional biomacromolecules by modifying the surface for fulfilling different applications. Dendrimers are being used for crosslinking of existing synthetic and natural polymeric scaffolds to regulate their binding efficiency, stiffness, biocompatibility, transfection, and many other properties to mimic the in vivo extracellular matrix in tissue engineering and regenerative medicine (TERM). Dendritic inter-cellular linkers can enhance the linkages between cells and result in scaffold-independent tissue constructs. Effectively engineered dendrimers are the ideal molecules for delivering bioactive molecules such as cytokines, chemokines, growth factors, etc., and other metabolites for efficaciously regulating cell behavior. Dendrimeric nanostructures have shown tremendous results in various TERM fields like stem cells survival, osteogenesis, increased crosslinking for eye and corneal repair, and proliferation in cartilage. This review highlights the role and various aspects of dendritic polymers for TERM in general and with respect to specific tissues. This review also covers novel explorations and insights into the use of dendrimers in TERM, focusing on the developments in the past decade and perspective of the future.

Abstract
Conventional immunoassays such as ELISA and FLISA have been used for clinical diagnosis for a long time. These assays are complex, time-consuming, and uneconomical. They have been overwhelmed with newer and more efficient methods such as electrochemical and electrochemiluminescent immunosensors that are cost-effective and require less time. Immunosensor is a biosensor that consists of a signal transducer and a biologically interactive system such as antigen and antibody interaction. Recent advances in nanotechnology have seen numerous efforts towards the usage of nanoparticles such as dendrimers in immunoassays. Dendrimers are highly branched structures with a high density of active peripheral groups, expanding their wide range of applications in immunoassays. A vast number of peripheral groups enrich the sensitivity of the immunosensor by governing the orientation of the antibody on the sensor surface. The current review highlights recent progress and developments in applying dendrimers for different immunoassays and their applicability in analyzing various biomarkers in clinical disease diagnosis.

Abstract
Background
Cardiovascular diseases are the leading cause of death around the world,South Asian population are at higher risk of atherosclerotic coronary artery diseases (CAD) comparatively. There is a recommended physical activity level to prevent atherosclerotic cardiovascular disease (ASCVD). Health care professionals especially doctors are main advisors to prescribe the exercise protocols among general population. Hence we conducted a survey among doctors of Pakistan to identify their physical activity as well as their knowledge and attitude toward recommended physical activity.
Methodology
An online questionnaire was shared with doctors of various specialties working in private and public healthcare system of the Pakistan. It consisted of consent for participation,followed by information regarding demographic profile, preexisting co-morbid conditions, opinion regarding importance of physical activity to prevent ASCVD (5 point scale), perceived physical activity level (4 point scale), knowledge regarding ACC recommended physical activity level for primary prevention of ASCVD, lifestyle, and barriers in following recommended physical activity level. Collected data were entered and analyzed using SPSS version 21.0, participants were categorized into two groups as “cardiologists” and “non-cardiologists” and results were compared between the two groups.
Results
A total of 159 doctors participated in the survey, out of whom 97 (61%) were cardiologist and remaining 62 (39%) were affiliated with other specialties. Male participants (72.3%) were predominant and mean age was 30.44±23.16 years. More than 60% (61.6%) of the participants were free of preexisting co-morbid condition, most common ASCVD risk factor was positive family history (26.4%) followed by smoking (7.5%) and hypertension (6.3%). According to BMI, 21.4% (34) were obese and 40.3% (64) were overweight. A total of 74.8% (119) of the participants claimed to know about ACC recommended physical activity level but 65.5% (78) were actually aware of recommended 150 min of moderate-intensity or 75 min of vigorous-intensity aerobic activity level. According to the lifestyle activities only 26.4% (42) of the participants were found to follow the ACC recommended physical activity level per week, this proportion was same between cardiologists and non-cardiologists, 25.8% vs. 27.4% respectively. Lack of time from daily routine (71.7%) was found to be most commonly stated reason for physical in activeness followed by overburden/over stress at workplace (33.3%) and lack of resources (14.5%).
Conclusion
Knowledge and adherence to the ACC recommended physical actively level was poor among both cardiologists and non-cardiologists even after considering it important for the primary prevention of ASCVD. Majority of doctors were overweight and obese.Lake of time and resources and over stressed work life of doctors are the key barriers in following recommended physical activity level.

Abstract
INTRODUCTION The development of robot-assisted urological surgery is held back by the lack of robust medico-economic analyses and their heterogeneity. We conducted a medico-economic study to evaluate the implementation of measures to optimize the transition to robotic surgery. METHOD We carried out a single-center, controlled study from the point of view of the public healthcare establishment for 4 years. Economic data collection was based on a micro-costing method and revenues from stay-related groups. Clinical data corresponded to mean lengths of stay, operating duration, complications and stays in intensive care. The measures to optimize the transition to robotic, implemented mid-study period, enabled before/after comparison. RESULTS Altogether, 668 patients undergoing robotic surgery were included. Robotic activity increased significantly from periods 1 to 2 to 256% (P=<0.001) as did the overall proportion of robotic by 45% to 85% (P=<0.001). The mean lengths of stay fell significantly, 6.8 d vs. 5.1 d (P<0.001). Costs and revenues increased significantly, resulting in a persistent deficit for the activity €226K vs. €382K (P=<0.001). With increased volume of activity, the deficit per operation and the cost per minute of robotic operating room fell significantly, €3,284 vs. €1,474/procedure (P=<0.001) and €27 vs €24/min (P=<0.029), tending towards a break-even point (=zero deficit) at 430 operations per year. CONCLUSIONS Robotic-assisted surgery can be significantly optimized by implementing measures for the robotic turn to reach a break-even point at 430 operations per year. A better multidisciplinary case mix could lower the break-even volume of activity in short term. LEVEL OF EVIDENCE 3.

Abstract
Funding Acknowledgements Type of funding sources: None. Introduction Hydroxychloroquine(HCQ) use alone or in combination with Azithromycin (AZM) in SARS-CoV-2 infection is associated with QTc prolongation and risk of arrhythmias. Objectives To determine changes in QTc interval and factors predictive of extreme QTc prolongation in patients receiving HCQ alone or in azithromycin combination in Pakistani patients. Methodology Retrospective review of records of hospitalized patients with SARS-Cov2 RT-PCR positive result who received HCQ or HCQ/Azithromycin in combination from March-May 2020. Baseline ECGs as well as post drug use ECGs data was recorded. Tisdale score was calculated for predicting risk of QTc prolongation,QTc interval was calculated using Bazett formula. Data entry and analysis was done in SPSS version 23. Results A total of 134 patients were included in the study. 82.1%(110) were males and 17.9%(24) were females, mean age was 54.9 ± 13.7 years. 61.2% (82) had severe disease and 38.8 %(52) had non-severe disease. 14.2%(19) had history of cardiac disease, 35.8%(48) had hypertension and 35.1%(47) had diabetes mellitus. 70.1% (94) patients had received HCQ, AZM, or HCQ/AZM in combination. 40(29.9%) patients had not received any drug. Median baseline QTc among controls and non-control group was 383.5 (IQR 342.25-413.75)msec and 379(IQR 358-402)msec respectively. HCQ alone was administered to 26.9%(36) and HCQ/AZM to 33.6%(45) patients. 55.6% (45/81) developed QTc prolongation(QTc> 480 msec) or delta QTc increase > 60 msec. 6.2%(5/81) had absolute QTc > 500 msec post-drug administration. 55.6%(25/45) and 30.6%(11/36) (p-value 0.024) developed QTc prolongation in combination and HCQ alone groups respectively. Delta QTc increased to >60msec in 42.0% (34/81); 53.3%(24/45) in combination group and in 27.8%(10/36) of those receiving HCQ alone( p-value 0.021). Median delta change was 63( IQR 25-81) and 48.5(IQR 26.25-66.75) msec; Median Day 2 QTc was 413.5 msec (IQR 377.5-436) and 413 msec (IQR361-447); and median maximum QTc was 447(IQR391-471) and 429.8(IQR401.5-45.75) msec in those receiving HCQ/AZM combination and HCQ alone respectively. 9%(12/134) had arrhythmias during hospital stay, in 8.9% (4) and 5.6%(2) patients of those receiving HCQ/AZM combination and HCQ alone respectively, no patient developed torsade de pointes, one patient had non-sustained VT. There was no statistically significant association of QTc prolongation with mortality, acute kidney injury, myocardial injury or severity of disease. Diuretic use was found to be statistically significant association with QTc prolongation(p-value 0.038). There was a weak correlation of baseline QTc with Δ QTc(r = 0.207 and p-value 0.017) Conclusion QTc prolongation was observed in a significant population of patients receiving HCQ and HCQ/AZM combination, however, no significant life threating arrhythmias occurred.

Abstract
Introduction: Immune checkpoint inhibitors (ICI) therapy has led to a paradigm shift in cancer drug development and in the clinical evaluation of approaches to combination cancer treatment. Dysregulation of the immune system by ICI therapy may also elicit autoimmune phenomena and consequently manifest clinically as immune-related adverse events (irAEs) including neurological irAEs. Areas Covered: The purpose of this review is to explore the role of autoantibodies in the diagnosis and prediction of neurological irAEs and to evaluate their pathogenicity. We searched Pubmed and Embase for neurological irAEs and associated autoantibodies and found 28 patients with central and peripheral neurological irAEs. Of these patients, up to 40% had encephalitis, 34.4% with myasthenia gravis and 22% of patients with peripheral neuropathy and Guillain-Barre Syndrome had autoantibodies. Expert Opinion: Overall, our survey suggested a causal relationship between neurological irAEs and autoantibodies. Detection of autoantibodies may help to diagnose neurological irAEs and inform their clinical management.

Abstract
Introduction Lors de la première vague épidémique Covid-19, des mesures de triage, sans PCR systématique, étaient mises en place pour sélectionner les patients à opérer. Notre étude a comparé leurs résultats chirurgicaux après triage à ceux d’un groupe contrôle. Matériel L’analyse portait sur l’ensemble des patients initialement programmés dans un centre Covid de référence et inclus consécutivement, du 15 mars au 1er mai 2020 (NCT04352699). Leurs données étaient recueillies prospectivement et ultérieurement comparées à celles des patients opérés 1 an auparavant sur la même période dans ce centre. Le critère d’évaluation principal était l’admission post-opératoire en unité de soins intensifs (USI). La morbidité, la mortalité postopératoire, le report d’interventions, les tests PCR étaient évalués. Des analyses de sous-groupes étaient réalisés pour les patients opérés de cancer. Résultats Après triage, 96 des 142 interventions programmées ont dû être reportées. Sur les opérés, 48 (68 %) l’étaient pour cancer. Au total, aucun cas de pneumonie Covid-19 post-opératoire n’a été identifié. Trois patients (4 %) ont été admis en USI, dont un finalement décédé pour sepsis urinaire. Chez ces patients, les RT-PCR étaient négatives. Globalement, comparativement au groupe contrôle, aucune différence d’admission en USI, ni de taux de mortalité post-opératoire n’ont été rapportées. Conclusions Le triage de la première vague n’a pas surexposé les patients sélectionnés à un risque de complication ou de décès post-opératoire, particulièrement pas pour ceux opérés pour cancer. En revanche, 67 % des patients ont été reportés, avec un risque associé à des retard de soins pouvant conduire au décès. Niveau de preuve 3.

Abstract
The family of Boltorn™ H40 dendrimers is an imperative subclass of hyperbranched biodegradable polymers (HBPs), which has received mounting attention as a result of its inimitable chemical, physical and biodegradable properties. These properties embrace three-dimensional dendrimeric nanoarchitecture to avert tanglement between polymer branches, adequate spatial cavities for increased encapsulation of guest molecules, good solubility as well as low viscosity to improve processability, and a huge number of surface functional groups for chemical manipulations. Similarly, low toxicity, non-immunogenicity, and natural biodegradation are significant and critical advantages in therapeutic applications as compared to other dendritic polymers. All these characteristics of Boltorn™ H40 are of pronounced importance for planning and developing advanced targeted cargo delivery carriers for cancer therapy. The present review highlights the applications of Boltorn™ H40 HBPs for the transport of chemotherapeutic agents to manage various types of cancers.

Abstract
ObjectivesTo emphasise the importance of motor evoked potential (MEP) recordings from a simple urethral sphincter electrode along with routine use of bulbocavernosus reflex recordings, anal sphincter and other lower limb muscle free running and stimulated EMG and MEP’s, and SEP techniques for sphincter preservation.DesignCase report.SubjectsPatients with conus or other spinal lesions at risk of postoperative sphincter disturbance.MethodsTranscranial ‘train of 5’ stimulation (5 pulses, interstimulus interval 4msec, 200 µsec pulse width) was applied, with recordings from the urethral sphincter (small electrode taped to Foley catheter to lie just inside the urethra, referred to nearby needle anteriorly in mons pubis) and anal sphincter (paired needle electrodes in both left and right sides of external sphincter).ResultsIntraoperative stimuli of structures during dissection at one point gave a motor response confined to the urethral sphincter suggesting that these fibres may have been considered non-functional and cut had these not been assessed separately. Urethral sphincter MEP’s during the dissection confirmed that these motor fibres remained in continuity throughout.. The patient was intact after tumour removal.ConclusionsThis is an avant-garde technique by which we managed to save the nerve supply to the urethral sphincter and eventually urinary continence which would have been compromised if separate urethral monitoring was not attempted along with usual intraoperative nerve monitoring. We believe its first in the UK.

Abstract
Background and context: In Africa, up to two thirds of breast cancer patients have been reported to present with an advanced stage of III or IV at diagnosis leading to a disproportionately higher mortality. In Kenya, breast cancer is the most common cancer in females in terms of diagnosis and mortality. Metastatic breast cancer (MBC) patients are an ignored part of the breast cancer community as they are marginalized in many of the breast cancer related initiatives. MBC suffer from clinical depression, anxiety and four out of five of these women do not receive any services, referral or guidance to help them with their emotional distress. Preferred evidence based methods of support desired by women with MBC, include online support. International resources are not always applicable to the local context thus making them unattractive for people from diverse cultures and background, such as those from Africa. Kenya has a high percentage of literate females and highest Internet usage in the area. This provides a unique opportunity in an otherwise limited resource country to reach out to a significant population of MBC patients. The patients voices are a valuable and trustworthy assessment of their actual needs. They have been used frequently in the area of cancer as a first step in designing needs-tailored interventions. We propose to develop a virtual online forum with the aim of providing patients with MBC, and their caregivers an interactive forum for psycho social support, addressing stigmas, seek relevant clinical advice, find links to the nearest healthcare facilities, download helpful information, participate in support group activities and receive links to other important helpful sites that are locally relevant. We also propose that such forum should also reflect the needs of our patients as described by themselves. Aim: Primary aim of this project is developing a virtual online interactive support forum where MBC patients and their caregivers can access information on social, psychological, spiritual, religious and clinical needs. The purpose is to be partly achieved by assessing the patient needs by needs assessment survey and to evaluate the impact of such intervention on patient knowledge and satisfaction with care. Strategy/Tactics: Web site development is the key component of the project. Patients would be asked to fill out the Supportive Care Needs Survey/The Knowledge Assessment Tool. The surveys will take place at four major cancer treatment hospitals in Kenya. Postlaunch promotion and awareness about Web site will be made and, usage data and knowledge tool to be used to assess the impact and acceptability. Web site updated regularly to address issues identified. Program/Policy process: Information gathered would be made part of policy on national cancer strategy, recommendations to factor in identified patient needs in policy. What was learned: Ongoing process.

Abstract
Background Toxicity associated with chemotherapy is a major therapeutic challenge and is caused by chemotherapy-induced DNA damage and inflammation. We have recently reported that cell-free chromatin (cfCh) fragments released from dying cells can readily enter into healthy cells of the body to integrate into their genomes and induce DNA double-strand breaks, apoptosis and inflammation in them. We hypothesized that much of the toxicity of chemotherapy might be due to release of large quantities of cfCh from dying cells that could trigger an exaggerated DNA damage, apoptotic and inflammatory response in healthy cells over and above that caused by the drugs themselves. Methods We tested this hypothesis by administering cfCh neutralizing/degrading agents namely, anti-histone antibody complexed nanoparticles, DNase I and a novel DNA degrading agent-Resveratrol-Cu concurrently with five different chemotherapeutic agents to examine if chemotherapy-induced toxicity could be minimized. Results We observed (i) significant reduction in chemotherapy-induced surge of cfCh in blood; (ii) significant reduction in chemotherapy-induced surge of inflammatory cytokines CRP, IL-6, IFNγ and TNFα in blood; (iii) abolition of chemotherapy-induced tissue DNA damage (γH2AX), apoptosis (active caspase-3) and inflammation (NFκB and IL-6) in multiple organs and peripheral blood mononuclear cells; (iv) prevention of prolonged neutropenia following a single injection of adriamycin and (v) significant reduction in death following a lethal dose of adriamycin. Conclusion Our results suggest that toxicity of chemotherapy is caused to a large extent by cfCh released from dying cells and can be prevented by concurrent treatment with cfCh neutralizing/degrading agents.

Abstract
We performed a randomised, controlled, cross-over study of lung ventilation by Basic Life Support-trained providers using either the Tulip GT® airway or a facemask with a Guedel airway in 60 anaesthetised patients. Successful ventilation was achieved if the provider produced an end-tidal CO2 > 3.5 kPa and a tidal volume > 250 ml in two of the first three breaths, within 60 sec and within two attempts. Fifty-seven (95%) providers achieved successful ventilation using the Tulip GT compared with 35 (58%) using the facemask (p < 0.0001). Comparing the Tulip GT and facemask, the mean (SD) end-tidal CO2 was 5.0 (0.7) kPa vs 2.5 (1.5) kPa, tidal volume was 494 (175) ml vs 286 (186) ml and peak inspiratory pressure was 18.3 (3.4) cmH2 O vs 13.6 (7) cmH2 O respectively (all p < 0.0001). Forty-seven (78%) users favoured the Tulip GT airway. These results are similar to a previous manikin study using the same protocol, suggesting a close correlation between human and manikin studies for this airway device. We conclude that the Tulip GT should be considered as an adjunct to airway management both within and outside hospitals when ventilation is being undertaken by Basic Life Support-trained airway providers.

Abstract
Very small embryonic-like stem cells (VSELs) are immature primitive cells residing in adult and fetal tissues. This study describes enrichment strategy and molecular and phenotypic characterization of human cord blood VSELs. Flow cytometry analysis revealed that a majority of VSELs (LIN(-)/CD45(-)/CD34(+)) were present in the red blood cell (RBC) pellet after Ficoll-Hypaque centrifugation in contrast to the hematopoietic stem cells (LIN(-)/CD45(+)/CD34(+)) in the interphase layer. Thus, after lyses of RBCs, VSELs were enriched using CD133 and SSEA4 antibodies. These enriched cells were small in size (4-6 μm), spherical, exhibited telomerase activity and expressed pluripotent stem cell (OCT4A, OCT4, SSEA4, NANOG, SOX2, REX1), primordial germ cell (STELLA, FRAGILIS) as well as primitive hematopoietic (CD133, CD34) markers at protein and transcript levels. Heterogeneity was noted among VSELs based on subtle differences in expression of various markers studied. DNA analysis and cell cycle studies revealed that a majority of enriched VSELs were diploid, non-apoptotic and in G0/G1 phase, reflecting their quiescent state. VSELs also survived 5-fluorouracil treatment in vitro and treated cells entered into cell cycle. This study provides further support for the existence of pluripotent, diploid and relatively quiescent VSELs in cord blood and suggests further exploration of the subpopulations among them.

Abstract
OBJECTIVES To examine the effects of the geko™ device (a portable electical nerve stimulator) on microcirculatory flow on the dorsum of the foot, and whether this is influenced by lower limb postures and application of a plaster cast. STUDY DESIGN Cross-sectional, healthy cohort, open label, physiological response study. METHODS In 10 healthy volunteers, aged 19 to 24 years, Laser Doppler Fluxmetry measurements were made on the dorsum of the foot in four postures: standing (weight bearing and non-weight bearing) and supine lying (with the lower limb horizontal and then elevated). Measurements of flux were made both at rest and during stimulation with the geko™ device applied over the common peroneal nerve, at 1Hz for 5 minutes in each posture. Repeat measurement were made after the application of a below knee plaster cast. Measures of flux were compared to basal levels assumed to be in supine with limb horizontal, with no cast and an inactive Geko device. RESULTS The geko™ device was effective in increasing microcirculation on the dorsum of the foot in all four postures (Mean difference =141%, 95% CI 70%-212%, p=0.001). This effect was more pronounced than that of using a plaster alone (Mean increase in Flux of 73%, 95% CI 22%-125%, p=0.01) or variances due to the hydrostatic effects of different postures (Mean difference 17-27.6%, p>0.05). There was a 2 to 3 fold increase in flux when stimulation was delivered in combination with the plaster cast. CONCLUSIONS Stimulation using the geko™ device augments microcirculation in the foot. The response is greater in lying and non-weight bearing than weight bearing standing but the most striking effect is when stimulation is combined with a plaster cast. The geko™ offers a potential means of promoting conditions favourable for wound healing, where treatment using compression may be contraindicated, such as arterial/mixed aetiology ulcers.

Abstract
The Tulip airway is an adult, disposable, single-sized oropharyngeal airway, that is connectable to an anaesthetic circuit. After a standardised induction of anaesthesia in 75 patients, the ease of insertion, intracuff pressure and intracuff volume were measured, as were the end-tidal carbon dioxide levels, airway pressures and tidal volumes over three breaths. Successful first-time insertion was achieved in 72 patients (96%, CI 88.8-99.2%) and after two attempts in 74 patients (99%, CI 92.8-100%). There was outright failure only in one patient. In 60 patients (80%, CI 72.2-90.4%), the Tulip airway provided a patent airway without additional manoeuvres, but in 14 patients, jaw thrust or head extension was necessary for airway patency. The main need for these adjuncts appeared to be an initial under-inflation of the cuff. These promising results are consistent with recent manikin studies using this device.

Abstract
Objectives We aimed to examine the characteristics of deep venous flow in
the leg in a cast and the effects of a wearable neuromuscular stimulator
(geko; FirstKind Ltd) and also to explore the participants’ tolerance
of the stimulator. Methods This is an open-label physiological study on ten healthy volunteers.
Duplex ultrasonography of the superficial femoral vein measured
normal flow and cross-sectional area in the standing and supine
positions (with the lower limb initially horizontal and then elevated).
Flow measurements were repeated during activation of the geko stimulator
placed over the peroneal nerve. The process was repeated after the
application of a below-knee cast. Participants evaluated discomfort
using a questionnaire (verbal rating score) and a scoring index
(visual analogue scale). Results The geko device was effective in significantly increasing venous
blood flow in the lower limb both with a plaster cast (mean difference
11.5 cm/sec-1; p = 0.001 to 0.13) and without a plaster
cast (mean difference 7.7 cm/sec-1; p = 0.001 to 0.75).
Posture also had a significant effect on peak venous blood flow
when the cast was on and the geko inactive (p = 0.003 to 0.69),
although these differences were less pronounced than the effect
of the geko (mean difference 3.1 cm/sec-1 (-6.5 to 10)).
The geko device was well tolerated, with participants generally
reporting only mild discomfort using the device. Conclusion The geko device increases venous blood flow in the lower limb,
offering a potential mechanical thromboprolylaxis for patients in
a cast. Cite this article: Bone Joint Res 2013;2:179–85.

Abstract
Nephrogenic systemic fibrosis (NSF) is a debilitating disease in patients with severely diminished kidney function. Currently, no standard treatment exists but improvement has been reported after restoration of kidney function. We retrospectively studied 17 NSF patients with and without successful kidney transplantation (KTx) to evaluate the effects of KTx on NSF. Nine of the 11 KTx developed NSF pretransplant whereas two developed NSF immediately after KTx with delayed graft function. Two of the six dialysis patients had previous failed kidney transplants. Age and sex were well matched. All but one patient was dialysis dependent at the time of NSF. Median follow-up was 35 months for KTx patients and 9 months for dialysis patients. Kidney transplants achieved adequate renal function with median serum creatinine of 1.4 (0.9-2.8) mg/dL and a glomerular filtration rate of 42 (19-60) mL/min/1.73 m(2). NSF improved in 54.6% of the transplanted patients and 50% of the nontransplanted patients (p = 0.86). Two KTx patients had complete resolution of their symptoms whereas four had partial improvement. Improvement in the dialysis patients was all partial. Successful KTx did not insure improvement in NSF and in fact appeared to have no significant benefit over dialysis.
