Abstract
STUDY OBJECTIVE Due to the rarity of the Andersson lesion (AL), the literature is ambiguous regarding the type of surgical fixation, need for debridement and deformity correction. The purpose of this retrospective study is to evaluate the efficacy, feasibility and functional outcome of posterior fixation in AL. MATERIALS AND METHODS This study included 35 patients having thoracolumbar AL operated for in situ fixation and fusion with minimum of 24-month follow-up. VAS (Visual Analogue Score) back pain, ODI (Oswestry Disability Index), Frankel's grade were compared and analyzed. Union status was noted with complications. RESULTS The mean age of 35 patients was 56.34(± 11.3) years with average follow-up of 51.49 months. Two patients had AL at two levels. 27/37 AL were at discal level. Average estimated blood loss (EBL) was 276.43 ml and duration of surgery was 130.43 min. On an average, operated segments needed 7.77 screws. There were ten minor complications without long-term sequel. Neurological improvement was noted in 30 patients. Average preoperative VAS score improved from 8.69 to 3.14, ODI score improved from 68.76 to 18.77 at final follow-up which were significant (p < 0.05). There was significant improvement in Frankel's grading (Z = - 4.354, P = 0.00). CONCLUSIONS Surgical management of AL by posterior approach and posterior stabilization can give satisfactory results without the need of extensive anterior reconstruction, bone grafting or deformity correction procedures without added morbidity and complications.

Abstract
At the macro-level, behavioral finance challenges classic financial theories. It shows that investor behavior in the real world is incompatible with the fundamental assumption of rationality in traditional finance, as studied by Sedaghati. While taking decisions, including financial decisions, rational thoughts are not involved, as suggested by modern theory. Additionally, these decisions are taken by them are also often inconsistent. Contrarily, human decisions are subject to several irrational principles, as in an evaluator study by Kannadhasan. These decisions are taken by considering the risks and returns involved. Prospect theory is one of the many theories derived from behavioral finance was first invented in a 1979 paper by Daniel Kahneman and Amos Tversky. It is commonly seen as the best explanation of how people evaluate risk in experimental settings, as researched by Barberis. This theory mainly includes how individuals or groups of investors decide between the alternatives under the umbrella of risk and uncertainty. This research evaluates the stock investors’ behaviors during the COVID-19 phase in India using prospect theory; many factors affect the decision of stock investors, such as loss aversion, risk aversion, certainty effect, reflective effect, etc., observed by Kahneman & Tversky. This study explores the possibility of factors of prospect theory on investors’ decisions about their investments during the COVID-19 phase. The results provide insights into how individual investors’ decisions vary during this pandemic situation.

Abstract
We consider the N particle classical Riesz gas confined in a one-dimensional external harmonic potential with power-law interaction of the form 1/r^{k}, where r is the separation between particles. As special limits it contains several systems such as Dyson's log-gas (k→0^{+}), the Calogero-Moser model (k=2), the 1D one-component plasma (k=-1), and the hard-rod gas (k→∞). Despite its growing importance, only large-N field theory and average density profile are known for general k. In this Letter, we study the fluctuations in the system by looking at the statistics of the gap between successive particles. This quantity is analogous to the well-known level-spacing statistics which is ubiquitous in several branches of physics. We show that the variance goes as N^{-b_{k}} and we find the k dependence of b_{k} via direct Monte Carlo simulations. We provide supporting arguments based on microscopic Hessian calculation and a quadratic field theory approach. We compute the gap distribution and study its system size scaling. Except in the range -1<k<0, we find scaling for all k>-2 with both Gaussian and non-Gaussian scaling forms.

Abstract
Health care has a prominent place in society and as a settingrequired to serve and care for its public and stimulate overallphysical, psychological, and social health. It has a distinctobligation to generate a healthy workplace. Conflict and diversityare intrinsic in health care, and conflict in interdisciplinaryteams is an accepted norm and unescapable. Thus, astudy was conducted to understand reasons for the conflictamongst varied levels of healthcare staff in a 150 bedded multispecialtyhospital in an Indian city. A Survey of 200 respondents(Healthcare and managerial staff) revealed that lack ofappreciation, job stress, and competition within the department(32%) were the major reasons for differences amongstthe employees. Concerning approaches adopted, compromisingand collaborating methods scored more (38% and38.6%, respectively). The results have shown that, in general,managers are familiar with conflict resolution techniques andbelieve in motivating their staff to increase their levels of performanceand retain them with the hospital. However, thereis a need to make the human resource system more robustand accommodating to ensure varied healthcare professionalsfrom different qualification backgrounds and job roles aretreated equitably

Abstract
Introduction
Urology is a common rotation for UK Foundation Year (FY) doctors, and accounts for >25% of acute surgical referrals. In 2012, the British Association of Urological Surgeons (BAUS) produced ‘An Undergraduate Syllabus for Urology’, advising on common clinical areas of urology to be covered during medical school. However, its national uptake remains unknown. LEARN aims to assess undergraduate urology teaching across UK medical schools.
Method
LEARN is the largest ever multicentre cross-sectional study of undergraduate urology teaching. Year 2-5 medical students and FY1 doctors were invited to complete a survey between 3rd October-20th December 2020. The primary objective is to compare current undergraduate urology teaching against the BAUS syllabus. Secondary objectives investigate the type and quantity of teaching provided, the reported performance rate of GMC mandated urological procedures, and the proportion of those considering urology as a career.
Results
A total of 7,611/8,346 (91.2%) responses from 39 medical schools that met the inclusion criteria were analysed. 16.5% of responses were newly appointed FY1 doctors. In their undergraduate training, the most commonly taught topics were urinary tract infection, acute kidney injury and haematuria; the least taught topics were male urinary incontinence, male infertility and erectile dysfunction. 90.6% and 86.3% had reported performing catheterisation as undergraduates on male and female patients respectively, and 16.9% had considered a career in urology.
Conclusion
LEARN provides the largest evaluation of any undergraduate specialty teaching. It has identified areas to improve teaching, to equip the future workforce with the competencies to manage urological pathology, irrespective of future career choice.

Abstract
Introduction In the already high-risk, high-stress environment of the operating theatre, operating during Covid-19 has brought its own unique challenges. Communication, teamwork and anxiety related new operating practices secondary to Covid-19 are hypothesised to have a negative impact on patient care. Method We conducted a single-centre online survey of operating theatre staff from 22nd June–6th July 2020. Respondents completed 18 human factors questions related to COVID-19 precautions including communication, teamwork, situational awareness, decision making, stress, fatigue, work environment and organisational culture. Questions consisted of yes/no responses, multiple choice and Likert items. Kruskall-Wallis tests, Chi-Squared, Mann Whitney U tests, Spearman’s correlation coefficient, lambda and Cramer’s V tests were used. Free-text responses were also reviewed. Results 116 theatre staff responded. Visual (90.5%), hearing/ understanding (96.6%) difficulties, feeling faint/lightheaded (66.4%) and stress (47.8%) were reported. Decreased situational awareness was reported by 71.5% and correlated with visors (r = 0.27 and p = 0.03) and FFP2/3 mask usage (r = 0.29 and p = 0.01). Reduced efficiency of theatre teams was reported by 75% of respondents and 21.5% felt patient safety was at greater risk due to Covid-19 precautions in theatre. Conclusions Organisational adjustments are required, and research focused on development of fit-for-purpose personal protective equipment (PPE).

Abstract
Abstract
Introduction
Urological conditions account for approximately 25% of acute surgical referrals and 10-15% of general practitioner appointments. In 2012, the British Association of Urological Surgeons (BAUS) produced ‘An Undergraduate Syllabus for Urology’, advising on common clinical areas of urology that must be covered during undergraduate medical training. However, its uptake nationally remains unknown. This project aims to assess undergraduate urology teaching across UK medical schools.
Methods
A targeted advertising drive using social media, medical school societies, websites and newsletters was performed over 4 weeks. Collaborators are responsible for recruiting survey respondents (year 2 medical students to foundation year 1 (FY1) doctors). Survey respondents will complete a REDCap survey retrospectively assessing their urology teaching to date. The primary objective is to compare current urology teaching in medical schools across the United Kingdom with the BAUS undergraduate syllabus.
Results
Currently, 522 collaborators have registered from 36 medical schools nationally. Of these collaborators, 6.32% (33/522) are FY1s and 93.68% (489/522) are medical students. Each collaborator will be responsible for recruiting at least 15 survey respondents to be eligible for PubMed-indexed collaborator authorship.
Conclusion
LEARN has recruited successfully to date, with all collaborators from the medical student and FY1 cohort. With the role of collaborators to further recruit survey respondents, LEARN will provide the most representative and thorough evaluation of UK undergraduate urological teaching to date. It will provide evidence to support changes in the medical school curriculum, and allow re-evaluation of the current national undergraduate BAUS syllabus.

Abstract
Abstract
Introduction
Non-muscle invasive bladder cancer (NMIBC) is one of the most expensive cancers to treat, driven by high recurrence rates and disease progression. Mortality rates in the UK for all bladder cancers have remained relatively stable over the past decade. NMIBC can be curatively treated with transurethral resection of the bladder tumour (TURBT). Despite international evidence-based guidelines on the TURBT procedure and postoperative single instillation of mitomycin-C, TURBT quality continues to vary widely. RESECT will be the first ever international study of TURBT surgery evaluating the achievement of TURBT quality indicators globally and assessing if audit and performance feedback can improve surgical outcomes.
Methods
RESECT is a prospective, multicentre international observational cohort study. Collaborators at each site will collect data using REDCap about local TURBT practice, early recurrence rates and the experience of local TURBT surgeons. The primary outcome is the rate of achievement of key TURBT quality indicators. Advertisement for the study launched in 2020.
Results
As of October 1st, 2020, 524 collaborators have registered to participate. Collaborators represent 334 centres from 54 countries, with the highest number of centres from the United Kingdom (133), Spain (17), and India (16). 50.8% are trainees, 30.3% consultants, and 17.2% medical students. Based on current registrations, patient recruitment will far exceed initial projections and considerably improve statistical power.
Conclusion
RESECT has attracted many collaborators internationally from consultants and trainees at all stages. RESECT has significant potential to positively impact TURBT practice, health economics and ultimately improve outcomes for patients with NMIBC globally.

Regular participation in physical activity is critical for nurturing optimum health and well-being. It also prevents the onset of obesity and associated non-communicable diseases. Indeed, urban Indian men are more prone to these chronic illnesses as most of them lead a very sedentary lifestyle. Thus, a public health priority is to increase physical activity levels among sedentary urban Indian men. With this objective in mind, an exploratory study was designed to understand men's perspective of physical activity and the factors influencing physical activity participation.
Methods
Five focus group discussions (FGDs) were conducted with adult men (n = 26; age: 20-60 years) between August and November 2019. The participants were recruited from Mumbai Metropolitan Area through snowballing. All the FGDs were audio-recorded and conducted in both Hindi and English. The audio recordings were transcribed and translated. Content analysis was used to obtain frequencies of different barriers and facilitators. Thematic analysis was applied to cluster responses, identify themes in the data, and build an explanation from the FGDs.
Results
All the participants perceived the need to participate in physical activity as it was associated with a better quality of life. Commonly identified facilitators were health benefits, physical appearance, and adequate facilities in the neighbourhood to engage in physical activity. Self-reported barriers included lack of time because of hectic work schedules and commuting, laziness, physical activity not viewed as a priority, and engagement with mobile phones.
Conclusions
The emerging findings can inform the development of a physical activity intervention to support behaviour change as well as ensure its sustainability among inactive urban Indian men. This qualitative inquiry contributes to the body of knowledge on physical activity in a culture that is relatively underrepresented in the current literature.
Key messages
Physical activity was influenced by multiple factors at multiple levels i.e. intrapersonal level, interpersonal level, and community level. There is a need to design effective public health interventions to increase physical activity and thereby control the prevailing disease burden.

Abstract
OBJECTIVES As per National AIDS Control Organization (NACO) estimates, there are 2.1 million people living with HIV (PWH) in India, of whom 1.2 million are on first-line antiretroviral therapy (ART). This study explored the use of a single-tablet regimen containing tenofovir disoproxil fumarate 300 mg + lamivudine 300 mg + efavirenz 400 mg (TLE400 STR) as a first-line switch strategy in PWH in Pune, India. METHODS This retrospective cohort study was conducted in private sector ART clinics in three tertiary-level hospitals in Pune, India. PWH > 12 years of age (n = 502) who initiated first-line ART (predominantly TLE600 STR), completed ≥ 6 months of follow-up and achieved virological suppression [plasma viral load (VL) < 1000 HIV-1 RNA copies/mL] were identified and switched to TLE400 STR. The virological and immunological efficacy of TLE400 STR at 6 and 12 months of follow-up were noted. Grade 3/4 adverse events (especially efavirenz-related neuropsychiatric adverse events) leading to regimen discontinuation were also noted. RESULTS Of 502 PWH who switched to TLE400 STR, complete virological suppression (VL < 20 copies/mL) was maintained in more than 97% of patients at follow-up. TLE400 STR was successful in maintaining CD4 counts within the range observed at the start of the regimen. Grade 3/4 adverse events leading to TLE400 STR discontinuation were seen in 11 (2.2%) patients. Virological failure (VL > 1000 copies/mL) and treatment regimen failure were seen in six (1.2%) and 49 (9.8%) subjects, respectively. CONCLUSIONS TLE400 STR exhibits excellent efficacy and safety as a switch strategy and should be introduced in the Indian National ART Program, especially for PWH who are virologically suppressed on TLE600 STR.

Abstract
OBJECTIVES The risk of cardiometabolic complications in children with perinatally acquired HIV infection (PHIVs) and in perinatally HIV-exposed but uninfected children (HEUs) and its relationship to systemic inflammation and markers of gut integrity are not well established. In this current study, we assed insulin resitance in PHIV compared to HEUs and HIV unexposed uninfected children and explored potential association with intestinal damage biomarkers. METHODS This was a cross-sectional study in PHIVs, HEUs and HIV-unexposed, uninfected children (HUUs) aged 2-10 years enrolled in Uganda. PHIVs were on stable antiretroviral therapy (ART) with HIV viral load < 400 HIV-1 RNA copies/mL. Insulin resistance was estimated using the homeostasis model assessment of insulin resistance (HOMA-IR). We measured markers of systemic inflammation, monocyte activation and gut integrity. Kruskal-Wallis tests were used to compare markers by HIV status; Pearson correlation and multiple linear regressions were used to assess associations of the HOMA-IR index with biomarkers of intestinal damage and translocation. RESULTS Overall, 172 participants were enrolled in the study (57 PHIVs, 59 HEUs and 56 HUUs). The median age was 7.8 [interquartile range (IQR) 6.39, 8.84] years, 55% were female and the median body mass index (BMI) was 15 (IQR 14.3, 15.8) kg/m2 . Among PHIVs, the median CD4% was 37%, and 93% had viral load ≤ 20 copies/mL. PHIVs had higher waist:hip ratio, high-density lipoprotein (HDL) cholesterol, triglycerides and HOMA-IR index than the other groups (P ≤ 0.02). Factors correlated with insulin resistance included higher BMI and HDL cholesterol and lower soluble tumour necrosis factor receptor I (sTNFRI) (P ≤ 0.02). There was no correlation between any of the other inflammatory or gut biomarkers and HOMA-IR index (P ≥ 0.05). After adjusting for age and sTNFRI, BMI remained independently associated with the HOMA-IR index (β = 0.16; P < 0.01). CONCLUSIONS Despite viral suppression, Ugandan PHIVs have disturbances in glucose metabolism. Higher BMI, and not immune activation or alteration of gut integrity, was associated with insulin resistance in this population.

Abstract
We study an interacting system of N classical particles on a line at thermal equilibrium. The particles are confined by a harmonic trap and repel each other via pairwise interaction potential that behaves as a power law ∝∑[under i≠j][over N]|x_{i}-x_{j}|^{-k} (with k>-2) of their mutual distance. This is a generalization of the well-known cases of the one-component plasma (k=-1), Dyson's log gas (k→0^{+}), and the Calogero-Moser model (k=2). Because of the competition between harmonic confinement and pairwise repulsion, the particles spread over a finite region of space for all k>-2. We compute exactly the average density profile for large N for all k>-2 and show that while it is independent of temperature for sufficiently low temperature, it has a rich and nontrivial dependence on k with distinct behavior for -2<k<1, k>1 and k=1.

Abstract
Oxidative stress leads to the progression of many diseases including chronic wounds, atherosclerosis, stroke and cancer. The modification of biomolecules with reactive nitrogen or oxygen species has been shown to trigger oxidative stress pathways that are beneficial for healing. Extracellular matrix scaffolds have been used successfully in reconstructive applications due to the beneficial host response they induce. To tailor extracellular matrix scaffolds to enhance antioxidant response, ECM were prepared using reactive nitrogen or oxygen species. These scaffolds were shown to be effectively decellularized and possess oxidative or nitroxidative protein modifications. Macrophage responses in vitro and in an in vivo muscle injury model were shown to have enhanced antioxidant phenotypes without impairment of long-term remodeling. These observations suggest that ECM decellularized with reactive oxygen or nitrogen species could provide better outcomes for the treatment of ischemic diseases.

Abstract
Chronic granulomatous disease (CGD) is an inherited immunodeficiency disorder affecting the microbicidal function of the phagocytes. It is characterized by susceptibility to recurrent infections leading to significant morbidity and mortality. Antibacterial and antifungal prophylaxis, though, has significantly reduced the rate and severity of the infections; the breakthrough infections still remain a challenge. Currently, allogenic haematopoietic stem cell transplantation is the only curative option which is very expensive and unavailable for many due to lack of suitable donor. Thus, prenatal diagnosis (PND) forms an important component of management in the affected families. PND is challenging in families approaching late in pregnancy with an uncharacterized molecular defect. In such cases, PND can be performed by analysis of NADPH activity of fetal blood (FB) neutrophils at 18-20 weeks of gestation. Cord blood samples at 18 weeks of gestation from healthy control were used to establish normal ranges for NBT and DHR. PND was offered for six pregnancies (NBT: n = 3, DHR: n = 6) with index cases of CGD confirmed by abnormal NBT and DHR analysis. NBT and DHR tests were found to be negative for all the six cases, confirming the same on samples post-delivery. NBT and DHR tests offer a rapid and sensitive PND of CGD in the absence of facilities for molecular diagnosis. It was observed that addition of CD15 along with CD45 led to an accurate DHR analysis. It is recommended to perform the diagnosis with adequate precautions only at centres with considerable experience and expertise in the diagnosis of CGD.

Abstract
This paper examines the clinical problem of extensor tendon tethering and/or dorsal joint capsule tightening secondary to hand injury. One hundred and forty-one patients were examined 13 to 51 months after hand injuries of varying severity. Fifty-six patients (40%) had suffered simple and eighty-five patients (60%) complex injuries. Seventy-four (52%) of the 141 patients had no extensor tendon tethering and/or dorsal joint capsule tightening. In 30 (21%), the extensor tendon tethering and/or dorsal joint capsule tightening was considered to be “obvious” in that it was easily seen on examination using various commonly used clinical tests of finger flexion and extension. In 37 (26%), the extensor tendon tethering and/or dorsal joint capsule tightening was considered to be of “lesser degree” because it was only evident on application of specific tests which are described in this paper. Of the 37, 21 (56%) described themselves as being unable to make a “proper” fist with the injured hand, 33 (89%) had pain or discomfort on the dorsum of the injured hand and/or fingers on gripping ( P < 0.01) and 25 (70%) had weakness of power of gripping ( P < 0.01). Thirty-two (87%) complained of functional problems at work, with activities of daily living or with the pursuit of their hobbies.

Abstract
Bath engineering, which utilizes coupling to lossy modes in a quantum system to generate nontrivial steady states, is a tantalizing alternative to gate- and measurement-based quantum science. Here, we demonstrate dissipative stabilization of entanglement between two superconducting transmon qubits in a symmetry-selective manner. We utilize the engineered symmetries of the dissipative environment to stabilize a target Bell state; we further demonstrate suppression of the Bell state of opposite symmetry due to parity selection rules. This implementation is resource efficient, achieves a steady-state fidelity F=0.70, and is scalable to multiple qubits.

Abstract
Abstract
Background: The modified pectoral nerves block (Pecs II) as a method of analgesia for breast cancer surgery has shown excellent results in recent publications. This technique blocks the long thoracic nerve, thoracic intercostal nerves from T2-T6 & thoracodorsal nerve.
Aims: To evaluate the effectiveness of the Pecs II block for pain relief in the postoperative period of patients undergoing modified radical mastectomy (MRM).
Methods: A prospective comparative study was conducted at our instituition between November 2014 and March 2015. Patients scheduled to undergo MRM were randomly assigned to the test group (endotracheal anaesthesia along with Pecs II) and the control group (endotracheal anaesthesia only). In the postoperative period the patients were evaluated using a visual analogue scale to determine pain scores at 6, 12 & 24 hours.
Results: Fifty patients (25 in each group), between the ages of 24 to 76 years (54.76 ± 10) were included in the study. There was no significant difference in ages between test & control groups. In the postoperative period, the test group had significantly lower median pain scores at 6, 12 & 24 hours as compared to the control group.

Abstract
Titanium and titanium alloys exhibit a unique combination of strength and biocompatibility, which enables their use in medical applications and accounts for their extensive use as implant materials in the last 50 years. Currently, a large amount of research is being carried out in order to determine the optimal surface topography for use in bioapplications, and thus the emphasis is on nanotechnology for biomedical applications. It was recently shown that titanium implants with rough surface topography and free energy increase osteoblast adhesion, maturation and subsequent bone formation. Furthermore, the adhesion of different cell lines to the surface of titanium implants is influenced by the surface characteristics of titanium; namely topography, charge distribution and chemistry. The present review article focuses on the specific nanotopography of titanium, i.e. titanium dioxide (TiO2) nanotubes, using a simple electrochemical anodisation method of the metallic substrate and other processes such as the hydrothermal or sol-gel template. One key advantage of using TiO2 nanotubes in cell interactions is based on the fact that TiO2 nanotube morphology is correlated with cell adhesion, spreading, growth and differentiation of mesenchymal stem cells, which were shown to be maximally induced on smaller diameter nanotubes (15 nm), but hindered on larger diameter (100 nm) tubes, leading to cell death and apoptosis. Research has supported the significance of nanotopography (TiO2 nanotube diameter) in cell adhesion and cell growth, and suggests that the mechanics of focal adhesion formation are similar among different cell types. As such, the present review will focus on perhaps the most spectacular and surprising one-dimensional structures and their unique biomedical applications for increased osseointegration, protein interaction and antibacterial properties.

Abstract
The development of insecticide resistance is a threat to the control of malaria in Africa. We report the findings of a national survey carried out in Tanzania in 2011 to monitor the susceptibility of malaria vectors to pyrethroid, organophosphate, carbamate and DDT insecticides, and compare these findings with those identified in 2004 and 2010. Standard World Health Organization (WHO) methods were used to detect knock-down and mortality rates in wild female Anopheles gambiae s.l. (Diptera: Culicidae) collected from 14 sentinel districts. Diagnostic doses of the pyrethroids deltamethrin, lambdacyhalothrin and permethrin, the carbamate propoxur, the organophosphate fenitrothion and the organochlorine DDT were used. Anopheles gambiae s.l. was resistant to permethrin in Muleba, where a mortality rate of 11% [95% confidence interval (CI) 6-19%] was recorded, Muheza (mortality rate of 75%, 95% CI 66-83%), Moshi and Arumeru (mortality rates of 74% in both). Similarly, resistance was reported to lambdacyhalothrin in Muleba, Muheza, Moshi and Arumeru (mortality rates of 31-82%), and to deltamethrin in Muleba, Moshi and Muheza (mortality rates of 28-75%). Resistance to DDT was reported in Muleba. No resistance to the carbamate propoxur or the organophosphate fenitrothion was observed. Anopheles gambiae s.l. is becoming resistant to pyrethoids and DDT in several parts of Tanzania. This has coincided with the scaling up of vector control measures. Resistance may impair the effectiveness of these interventions and therefore demands close monitoring and the adoption of a resistance management strategy.

Abstract
The complex pathophysiology of chronic ulceration in diabetic patients is poorly understood; diabetes-related lower limb amputation is a major health issue, which has limited effective treatment regimes in the clinic. This study attempted to understand the complex pathology of hyperglycemic wound healing by showing profound changes in gene expression profiles in wounded human keratinocytes in hyperglycemic conditions compared to normal glucose conditions. In the hyper-secretory wound microenvironment of hyperglycemia, Rab18, a secretory control molecule, was found to be significantly downregulated. Using a biomaterial platform for dual therapy targeting the two distinct pathways, this study aimed to resolve the major dysregulated pathways in hyperglycemic wound healing. To complement Rab18, and promote angiogenesis eNOS was also targeted, and this novel Rab18-eNOS therapy via a dynamically controlled 'fibrin-in-fibrin' delivery system, demonstrated enhanced wound closure, by increasing functional angiogenesis and reducing inflammation, in an alloxan-induced hyperglycemic preclinical ear ulcer model of compromised wound healing.

Abstract
We report here a case of 26-year-old male who presented with history of recurrent acute renal failure associated with microangiopathic hemolytic anemia and thrombocytopenia. ADAMTS 13 deficiency due to mutation in the gene encoding for ADAMTS 13 was identified as the cause. After eight episodes of acute kidney injury (AKI), patient started developing hypertension, proteinuria, and renal insufficiency. Treatment with regular monthly plasma infusions prevented further episodes of AKI and stabilized the renal function. Hypertension and proteinuria are controlled with angiotensin II receptor blockers.

Abstract
PURPOSE To review our experience of laparoscopic nephroureterectomy and hemi-nephroureterectomy over a 10-year period. METHODS Forty patients had surgery between December 2000 and April 2010. Case notes were reviewed for clinical data, intraoperative time, complications, postoperative management, outcome and follow-up. RESULTS Mean age was 5.2 years. Thirty patients underwent nephroureterectomy. There were complications in five. Four required conversion. Two had bleeding from an adherent upper pole. One had adhesions from previous pyeloplasty. The fourth had a staghorn calculus secondary to xanthogranulomatous pyelonephritis. There were extensive inflammatory adhesions and despite early conversion, operating time was 9 h. Excluding this, mean operating time was 159 min. Nine patients underwent hemi-nephroureterectomy. There were complications in two; a hilar bleed and a peritoneal tear (neither required conversion). Mean operating time was 177 min. One patient with MCDK was for nephroureterectomy, but no renal tissue was found at laparoscopy and the procedure was abandoned. CONCLUSIONS Laparoscopic nephroureterectomy/hemi-nephroureterectomy is well tolerated in children and should be the preferred option. Operative time is acceptable. There are few complications. Patients with MCDK should have an ultrasound before surgery to confirm ongoing presence of renal tissue. In patients with xanthogranulomatous disease, laparoscopy should be avoided.

Abstract
We study collisions between two strongly interacting atomic Fermi gas clouds. We observe exotic nonlinear hydrodynamic behavior, distinguished by the formation of a very sharp and stable density peak as the clouds collide and subsequent evolution into a boxlike shape. We model the nonlinear dynamics of these collisions by using quasi-1D hydrodynamic equations. Our simulations of the time-dependent density profiles agree very well with the data and provide clear evidence of shock wave formation in this universal quantum hydrodynamic system.

Abstract
PURPOSE Genetic factors influence an individual's risk for developing age-related macular degeneration (AMD), a leading cause of irreversible vision loss. Previous studies investigating the potential association between all AMD subtypes and the SERPING1 gene, which encodes a key regulator of the classic complement pathway, have yielded conflicting results. The purpose of this study is to determine whether variations in SERPING1 are associated with neovascular AMD. METHODS A total of 556 patients with neovascular AMD and 256 ethnically matched controls were genotyped for polymorphisms in SERPING1. A tagging single nucleotide polymorphism (tSNP) approach was used to cover the SERPING1 gene plus 2 kb on each side, spanning the promoter and the 3' untranslated regions. Ten SNPs with a minor allele frequency of 0.10 were covered by three tSNPs (rs1005510, rs11603020, rs2511989). RESULTS SERPING1 SNPs rs1005510 and rs2511989 were significantly associated with neovascular AMD in our cohort, with rs1005510 conferring an adverse risk effect (OR 1.49, 95% CI 1.18 to 1.88) and rs2511989 conferring a protective effect (OR 0.73, 95% CI 0.59 to 0.90). For both tSNPs, logistic regression of individual genotypes demonstrated statistically significant stepwise changes in the risk of developing AMD. Combined analysis of rs1005510 with variants in CFH and HTRA1 confirmed an independent risk effect. The rs11603020 variant had no effect on AMD susceptibility in this study (OR 0.98, 95% CI 0.78 to 1.24). CONCLUSIONS The SERPING1 gene is comprehensively investigated in this study (using three tSNPs), and its genetic variants are evaluated in the largest neovascular AMD cohort to date. The hypothesis that SERPING1 has a modest effect on the risk of neovascular AMD is supported by our results.

Abstract
Leprosy is a chronic granulomatous infection, caused by mycobacterium leprae, primarily affecting the peripheral nerve trunks and cutaneous nerves. It classically presents with neural or dermal signs and symptoms. The indolent course of leprosy may manifest as erythema nodosum (appearance of tender inflamed subcutaneous nodule) and reversal reaction (inflammation in the previous skin lesion, appearance of new skin lesions, neuritis and abscess). Ulnar nerve is most commonly involved. This report illustrates the MR imaging appearance of ulnar nerve abscess.
