Abstract
AIMS COVID-19 pandemic has massively impacted human health. We studied the effect of COVID-19 on outcome of Diabetic foot ulcers (DFUs). OBJECTIVES AND METHODS We recruited 483 people with DFUs from June 2020 to April 2022 (pandemic) together with a matched group of 226 people with DFU from March 2019 to March 2020 (pre-pandemic). Primary endpoint was outcome of ulcers-healed or amputation (major/minor). It was sub-analysed into 3 waves of COVID-19. Secondary endpoint was healing of individual types of DFUs. Basic anthropometric data included site and type of ulcer (ischemic or neuropathic), duration, presence or absence of infection and Wagner's grading of DFUs was collected for all patients. Diagnosis of peripheral neuropathy was done by monofilament testing and peripheral arterial disease by handheld Doppler and ankle brachial index (ABI). Standardized treatment protocol was provided. All patients were monitored for 6 months. RESULTS In the pandemic group 323 (66.9%) patients in whom ulcers healed, 70 (14.5%) underwent minor amputation, 11 (2.2%) major amputation, 29 (6%) were lost to follow up, 22 (4.6%) were not healed. Rate of healing of DFU was higher (66.9% vs 53.5%) and rate of amputation was lower (16.7% vs 23.4%) in the pandemic group than in the pre-pandemic group (P = 0.001 and 0.037 respectively). Rate of healing in first, second and third wave was 65.4%, 75.2%, 58.3% respectively (P = 0.001). Neuropathic ulcers though less prevalent (49.8% vs 57.8%) in the first two waves than in the third wave, healing was better (79.3% vs 75.6%) in the first two waves than in the third wave (P = 0.085 and 0.488 respectively). Similarly, amputation rates in ischemic and neuro-ischemic ulcers were greater in the third wave than first two waves (46.7% vs 15.7%, P = 0.049). CONCLUSION During the COVID-19 pandemic, healing of neuropathic ulcers was better, especially in the first and second waves and travel restriction may have accounted for this. However, worsening of ischemic and neuro-ischemic ulcers was observed with more amputation in these two groups. Conversely, in the third wave withdrawal of lockdown led to worsening of DFUs resulting in less healing and more amputation.

Abstract
Dogs with B-cell lymphoma typically respond well to first-line CHOP-based chemotherapy, but there is no standard of care for relapsed patients. To help veterinary oncologists select effective drugs for dogs with lymphoid malignancies such as B-cell lymphoma, we have developed multimodal machine learning models that integrate data from multiple tumor profiling modalities and predict the likelihood of a positive clinical response for 10 commonly used chemotherapy drugs. Here we report on clinical outcomes that occurred after oncologists received a prediction report generated by our models. Remarkably, we found that dogs that received drugs predicted to be effective by the models experienced better clinical outcomes by every metric we analyzed (overall response rate, complete response rate, duration of complete response, patient survival times) relative to other dogs in the study and relative to historical controls.

Abstract
Exome sequencing (ES) has been used in a variety of clinical settings but there are limited data on its utility for diagnosis and/or prediction of monogenic liver diseases. We developed a curated list of 502 genes for monogenic disorders associated with liver phenotypes and analyzed ES data for these genes in 758 patients with chronic liver diseases (CLD). For comparison, we examined ES data in 7856 self-declared healthy controls (HC), and 2187 patients with chronic kidney disease (CKD). Candidate pathogenic (P) or likely pathogenic (LP) variants were initially identified in 19.9% of participants, most of which were attributable to previously reported pathogenic variants with implausibly high allele frequencies. After variant annotation and filtering based on population minor allele frequency (MAF ≤ 10-4 for dominant disorders and MAF ≤ 10-3 for recessive disorders), we detected a significant enrichment of P/LP variants in the CLD cohort compared to the HC cohort (X2 test OR 5.00, 95% CI 3.06-8.18, p value = 4.5e-12). A second-level manual annotation was necessary to capture true pathogenic variants that were removed by stringent allele frequency and quality filters. After these sequential steps, the diagnostic rate of monogenic disorders was 5.7% in the CLD cohort, attributable to P/LP variants in 25 genes. We also identified concordant liver disease phenotypes for 15/22 kidney disease patients with P/LP variants in liver genes, mostly associated with cystic liver disease phenotypes. Sequencing results had many implications for clinical management, including familial testing for early diagnosis and management, preventative screening for associated comorbidities, and in some cases for therapy. Exome sequencing provided a 5.7% diagnostic rate in CLD patients and required multiple rounds of review to reduce both false positive and false negative findings. The identification of concordant phenotypes in many patients with P/LP variants and no known liver disease also indicates a potential for predictive testing for selected monogenic liver disorders.

Abstract
The role of tumor interaction with stromal components during carcinogenesis is crucial for the design of efficient cancer treatment approaches. It is widely admitted that tumor hypoxic stress is associated with tumor aggressiveness and thus impacts susceptibility and resistance to different types of treatments. Notable biological processes that hypoxia functions in include its regulation of tumor heterogeneity and plasticity. While hypoxia has been reported as a major player in tumor survival and dissemination regulation, the significance of hypoxia inducible factors in cancer stem cell development remains poorly understood. Several reports indicate that the emergence of cancer stem cells in addition to their phenotype and function within a hypoxic tumor microenvironment impacts cancer progression. In this respect, evidence showed that cancer stem cells are key elements of intratumoral heterogeneity and more importantly are responsible for tumor relapse and escape to treatments. This paper briefly reviews our current knowledge of the interaction between tumor hypoxic stress and its role in stemness acquisition and maintenance. Our review extensively covers the influence of hypoxia on the formation and maintenance of cancer stem cells and discusses the potential of targeting hypoxia-induced alterations in the expression and function of the so far known stem cell markers in cancer therapy approaches. We believe that a better and integrated understanding of the effect of hypoxia on stemness during carcinogenesis might lead to new strategies for exploiting hypoxia-associated pathways and their targeting in the clinical setting in order to overcome resistance mechanisms. More importantly, at the present time, efforts are oriented towards the design of innovative therapeutical approaches that specifically target cancer stem cells.

Abstract
BACKGROUND Suicide is one of the ten leading causes of death in the United States. Childhood abuse, psychache (intense emotional pain), and interpersonal needs are widely known to be associated with suicidal thoughts and behaviors. However, only a limited number of studies investigate whether these variables, when analyzed collectively, are able to distinguish between a group of individuals who report suicidal ideation and those who deny such thoughts. PARTICIPANTS AND SETTING Data were collected from individuals (N =177) with a diagnosis of bipolar disorder participating in an intensive outpatient program that provides mental health care to indigent, mostly minority patients in Southeast United States. METHODS The dependent variable was item number 9 on the Beck Depression Inventory that asks about any suicidal thoughts in the past two weeks. We utilized discriminant analysis to test whether childhood abuse, interpersonal needs, and psychache were collectively able to accurately identify group membership of the study participants. RESULTS The discriminant model included six independent variables: three different types of childhood abuse (emotional, physical, and sexual), interpersonal needs (perceived burdensomeness and thwarted belongingness), and psychache. Results revealed that the model was able to correctly classify group membership in 75% of the individuals in the study. CONCLUSION In context of bipolar disorder, history of childhood abuse (particularly sexual and emotional abuse), intense psychache, and greater perceived thwarted belongingness and burdensomeness put an individual at a higher risk of suicidal ideation. Gaining insight into the interactions among these variables may lead to formulating early interventions to prevent suicide in patients reporting this constellation of symptoms.

Abstract
Healthy skin will never go out of style, and the advancements and improvements in the cosmetics industry guarantee to provide improved products with a healthy and personal touch. However, for consumers, it is difficult to assess the quality and effectiveness of a product. Extrinsic cues like the “Natural” or “Organic” labels are used to help the consumer distinguish between alternatives. This paper analyses how the organic label biases the consumers’ buying behavior, perceived value, and finally, the consumer’s purchase decision and the price he willingly pays for the product (willingness to pay). This phenomenon is known as the natural label halo effect. It further means to reveal the connections between the effect of the ‘Natural’ label on the factors affecting buying behavior and it’s out-turn as emulated in the consumer’s perceived value. It intends to identify if those outcomes at last lead to positive buying decisions and greater willingness to pay. A quantitative study in an experimental online shopping scenario was conducted to understand the relations. Structural equation modeling (SEM) was done to test the hypothesized statements. The results show that the halo effect of the ‘Natural’ label positively influences the factors affecting consumer buying behavior and eventually improves the probability of the product being bought by the consumer and also the price the consumer is willing to pay for it through inferential beliefs on quality attributes and functional value evoked by the label. The study also reveals that natural skincare products are perceived to be more compliant with a consumer’s beliefs/attitudes relating to environmental protection and animal protection, which positively influences the propensity of a consumer towards buying the product and paying a high price for it by increasing the perceived functional and hedonic values associated with the natural cosmetic product.

Abstract
Perinatal hypoxic-ischemic insult (HII) is one of the main devastating causes of morbidity and mortality in newborns. HII induces brain injury which evolves to neurological sequelae later in life. Hypothermia is the only therapeutic approach available capable of diminishing brain impairment after HII. Finding a novel therapeutic method to reduce the severity of brain injury and its consequences is critical in neonatology. The present paper aimed to evaluate the effect of sulforaphane (SFN) pre-treatment on glucose metabolism, neurodegeneration, and functional outcome at the acute, sub-acute, and sub-chronic time intervals in the experimental model of perinatal hypoxic-ischemic insult in rats. To estimate the effect of SFN on brain glucose uptake we have performed 18F-deoxyglucose (FDG) microCT/PET. The activity of FDG was determined in the hippocampus and sensorimotor cortex. Neurodegeneration was assessed by histological analysis of Nissl-stained brain sections. To investigate functional outcomes a battery of behavioral tests was employed. We have shown that although SFN possesses a protective effect on glucose uptake in the ischemic hippocampus 24 h and 1 week after HII, no effect has been observed in the motor cortex. We have further shown that the ischemic hippocampal formation tends to be thinner in HIE and SFN treatment tends to reverse this pattern. We have observed subtle chronic movement deficit after HII detected by ladder rung walking test with no protective effect of SFN. SFN should be thus considered as a potent neuroprotective drug with the capability to interfere with pathophysiological processes triggered by perinatal hypoxic-ischemic insult.

Abstract
BACKGROUND: Tobacco and TB are the world´s two greatest public health problems. Exposure to tobacco has been shown to be associated with higher risk of acquiring TB and adverse outcomes such as relapse and TB mortality.OBJECTIVE: To assess and compare self-reported tobacco quit status and biochemically verified cotinine levels among TB patients at different time intervals among two study groups.METHODS: A cluster, randomised controlled trial was conducted on TB patients attending DOTS centres in Delhi, India, who reported using tobacco in any form. Participants were assigned into one of two treatment groups. Centres were randomly assigned to two intervention groups: 1) integrated intervention using behavioural counselling with nicotine replacement therapy (NRT) gum, and 2) intervention using behavioural counselling alone (50 each in intervention and control group). The subjects were followed at Week 1, Month 1, Month 3 and Month 6 for tobacco cessation.RESULTS: At the end of 6 months, patients who received the integrated intervention had significantly higher rate of success in quitting tobacco than those who received the conventional TB treatment alone (78.7% vs. 57.8%; P < 0.03).CONCLUSION: DOTS with tobacco use dependence treatment was successful in our study in helping TB patients to quit tobacco dependence and should therefore be offered to every tobacco user.

Abstract
Abstract
Background
Paediatric forearm fractures are commonly encountered in Trauma and Orthopaedics. Currently most forearm fractures are manipulated in theatre the following day, increasing resource burden and delays in management. The aim of this project was to introduce guidelines to reduce fractures in the Emergency Department (ED) using intranasal Diamorphine and Entonox.
Method
197 cases were identified over a 6-month period in 2018 and 2019. 74 distal radial fractures and 123 mid shaft forearm fractures were analysed. Fractures with an intact periosteal hinge or a Salter Harris type 2 were reduced in ED. The pre manipulation and post manipulation radiographs were compared with particular attention to the post reduction angles.
Results
67% of fractures were reduced in the correct setting. A number of fractures reduced in ED required re-manipulation or internal fixation. Overall, there was a 56% reduction in patients undergoing general anaesthetic. There was a reduction in the mean length of stay from 36 hours to 3.5 hours.
Conclusions
Intranasal Diamorphine and Entonox offer a safe method for managing paediatric forearm fractures in ED. Implementation of this method facilitates early access to treatment and early patient discharge. Manipulation in ED offers significant financial savings and reduces demands on the Trauma Theatres.

Abstract
Abstract
Background: Early weight bearing (EWB) is increasingly considered acceptable in surgically managed fractures. However, there are two different outlooks for rehabilitation. EWB in a biologically weak bone may lead to implant failure compared to EWB being beneficial for quicker recovery. We aim to review outcomes for EWB in surgically managed fragility fractures.
Method: This was a retrospective analysis; data was collected from departmental records of operative fixation of lower limb injuries in patients above 60 years. We excluded patients who had procedures for proximal femoral fractures and polytrauma. We compared SF-12 scores, complications, and reoperation rates in those that were EWB to those that were at the conventional 6-week mark.
Results: During a 6-month period from November 2019 to April 2020 we performed 60 operations. N = 30 surgeries were performed in EWB group versus 30 surgeries in late weight bearing group (LWB). The average physical and mental SF-12 score in EWB group was 44.82 and 56.36 compared to a SF-12 score of 44.51and 52.18 in LWB.
Conclusions
We found that the SF-12 scores were different despite EWB. There was no evidence of early complications in the EWB group. Therefore, we advocate EWB for group >60 who were known to have osteoporosis.

Abstract
Background:Myths and misconceptions about illness and conventional disease modifying anti-rheumatic drugs directly influence adherence to the prescribed treatment. It is estimated that 30–50% of patients do not adhere to their prescribed treatment due to various reasons where the beliefs of the patients play a crucial role. At our centre we the specialist rheumatology nurse counsel the patients at every visit and try to remove their myths and negative beliefs about the disease as well as the medications.Objectives:•To explore the common myths and misconceptions of regarding their disease and regarding the csDMARDs.•To assess the efficacy of counseling in allaying their unfounded fear.Methods:A total of 450 patients with SIRDs at least 3 times attended the rheumatology out-patient clinic on csDMARDs were enrolled to complete a questionnaire that, besides demographic information, socio-economic status, and co- morbidities, had the following questions:1.Self reported adherence to medication2.Misbelieves regarding food items3.What kind of health-provider was consulted at the onset of the symptoms4.Their belief/knowledge regarding:A. The need for physiotherapy.B. Life style modification requirementC. About osteoarthritisD. Medication requirement during remissionE. Pregnancy and DMARDsF. The need of vaccinationG. Health hazards of smoking and alcohol useH. Harms of discontinuing treatment when they felt wellResults:A total of 450 patients included spondyloarthropathy 150(34%), rheumatoid arthritis 200(45.7%), psoriatic arthritis 45(10%), and others 25(5.5%).The following observations was made:1.Self-reported adherence to medication was in 250 (55%) patients; 200(45%) patient were non-adherent to treatment2.382/450 (85%) patients had misbelieves regarding different food items.3.225/450(50)% of the patients were not doing regular physiotherapy they were totally dependent on medications for symptoms relief.4.387/450 (86%) patients confused the symptoms of osteoarthritis with that of RA.5.315/450 (70 %) patients did not feel the requirement of continuing drugs during remission.6.135/450 (30%) patients believed that while on DMARDs they cannot contemplate pregnancy.7.351/450(78%) patients accept the need for vaccination when staring DMARDs8.360/450 (80%) patients aware about side effect of smoking in disease but only 40 % were able to quit.9.273/450 (60%) patients felt that more expensive medicines e.g.bDMARDs have more effects.10.360/450 (80%) patients believed that DMARDs were ‘steroids’ and they increased weight. On analysis one patient have more than two myths simultaneously.Conclusion:Increased awareness of the patient’s beliefs about medicines is needed among health care providers. We should encourage patients to express their views about medicines as well as disease in order to optimize and personalize the information process. This can stimulate concordance and adherence to medication and follow up.These myths are deeply rooted in our society, single sitting counseling is not enough, and reinforcement is needed.References:[1]Tom Greenhalgh.

Abstract
Background:Patients with systemic immunoinflammatory rheumatic diseases (SIRDs) are often treated with bDMARDs when the response to conventional disease-modifying antirheumatic drugs (csDMARDs) is inadequate.There are, however, concerns about non-adherence to bDMARDs among patient. The non-adherence to bDMARDs may be caused by the various factors.Objectives:1.The main objective of present study was to find out the cause of discontinuation of bDMARDs2.To find out the adherence and non-adherence rate for bDMARDs.3.To identify the factors that are modifiable.Methods:800patients with SIRDs prescribed bDMARDs were interviewed to find out the demographic information, their socioeconomic status,and the disease duration.Additional information gathered included the comorbidities, the time for starting bDMARDs, the route of administration of bDMARDs, beliefs and perceptions about treatment efficacy and side effects if any.This was followed by looking at the adherence of bDMARDs; if they had discontinued then efforts was made to find out the reasons for the same.Based on these findings the patients were classified into adherent and non-adherent categories. The data were analyzed further for1.Factors that associated with persistence of bDMARDs.2.Factors that were associated with discontinuation of bDMARDs.Results:A total of 800 patients were interviewed that included patients with ankylosing spondylitis 430(52.4%), rheumatoid arthritis 300(37.7%), psoriatic arthritis 45(5.2%), and others 25 (0.7%).On analysis 610(76%) patient were compliant but 190(24%) patient had discontinued the bDMARDs on their own. On comparison of both groupsFactors that were significantly related to self-discontinuation were:•Negative beliefs about biologics (37%)•Cost (33%)•Reading side-effect profile on Google search (25%)•Other co-morbidities (6%)Factors that were significantly related to persistence of biologic treatment were:•Good counseling by rheumatologist and rheumatology nurse (60%)•Faith in the treating rheumatologist (25%)•Fear of deformities and pain(15%)On analysis it was found that a good counseling and clarifying the doubts of the patients regarding bDMARDs before starting the treatment encourages the patient to continue the biologic treatment, especially it allays their doubts about the drug adverse effects.Conclusion:Despite negative beliefs and misconceptions about bDMARDs, patient non-adherence at our center is not alarming.A positive reinforcement counseling appears to be the most significant factor to overcome the negative belief of patients.The affordability of the biologic treatment however remains a limiting factor in our centre as in other parts of India.References:[1]Tamas Koncz,MD,Marta,Pentek,Valentin,Brodszky,Katalin Ersek,MSc,Ewaorlewska&Laszlo Gulasi Volume10,2010 –Issue9 Adherence to biologic DMARD therapies in rheumatoid arthritisAcknowledgments:noDisclosure of Interests:None declared

Abstract
Background:Systemic sclerosis (SSc) is an autoimmune the disease of the connective tissue that is clinically characterized by the involvement of skin (fibrosis, contractures of the finger joints), microvascular abnormalities (Raynaud’s phenomenon and complications), gastrointestinal involvement (gastroesophageal reflux disease - GERD, the lower GI tract involvement), musculoskeletal involvement (polyarthralgia, muscle disease), and involvement of internal organs (especially lungs, heart, and kidneys). Lifestyle modification techniques could have significant impact on various aspects of the disease including early disease control, increased drug adherence, positive attitude towards life, decreased financial burden of treatment, maintaining mobility and joints range of motion, minimizing or delaying joint contractures and decreased dependency with regular physical therapy. Counselling explaining the benefits of lifestyle modification related to these aspects of daily living may make a major difference in the quality of life of the patients with SSc.Objectives:To assess the benefits of lifestyle modification technique in improving the quality of life in patients with SSc.Methods:Patients with SSc attending the Rheumatology clinic of this institution, willing to participate in the survey, were enrolled in this study. All the information including the follow-up details were recorded in a pre-designed form. Their demographic information (age, gender) and disease characteristics (diagnosis, duration, treatment) were recorded, All the patients were explained the lifestyle modifications and their benefits, reinforced at each follow-up visit using posters (visual), written lifestyle modification techniques (using printed material) to raise their awareness of how to improve several of the above manifestations of SSc.Results:One hundred fifty (n=150) consecutive SSc patients were included in the study. It was observed that with repeated counselling 125 (83.3 %) patients adopted the lifestyle modification technique according to the advice imparted and felt a positive benefit in their daily life. However, 25 (16.6%) could not or did not follow the imparted lifestyle change advice on a regular basis. Those who were able to modify the life-style as counselled showed the following results:80 % were able to avoid exposure to cold by adopting the following measures: Wearing gloves and extra woolen socks, using mittens most of the time, wearing woollen undergarments to keep the central regions of the body region warm. These patients noted 55% decrease in the episodes of Raynaud’s phenomenon.Early evening meals and raising the head-end of the bed: 60% decrease in gastrointestinal symptoms.Regular physiotherapy: 65 % decrease dependency on others; 55% could maintain flexibility with physical exercises.Regular application and rubbing of the skin with lanoline-containing skin moisturizers 60 % improve your skin’s health80% were able to avoid active and passive tobacco use.Conclusion:The lifestyle modification techniques are important to control disease and its complications. Thus, after intense and regular counselling by the specialist rheumatology nurses on the lifestyle modification technique (83.3%) adapted the advised lifestyle modifications. The study showed the important role specialist rheumatology nurses can play in educating patients and helping them improving their quality of life.References:[1] Hudson M, Thombs BD, Steele R. at ell.

Abstract
Indian childhood cirrhosis is an entity believed to be on the verge of extinction. We present the case of a 13-month-old girl presenting acutely with jaundice, fever, and persistently increasing bilirubin. Investigations revealed direct hyperbilirubinemia, elevated transaminases, anemia, a blood with few schistocytes, positive direct coombs test, and deranged prothrombin time. Viral, autoimmune, and metabolic workup was unremarkable. Ultrasonography showed chronic liver disease, portal hypertension, and ascites. Due to numerous confounding factors and a low index of suspicion, the diagnosis of Indian childhood cirrhosis remained elusive and was clinched only on liver biopsy, albeit more than three weeks later, shortly after which the child expired. The timing and technique of the liver biopsy may have profound impact on the ultimate clinical outcome. Close coordination between the clinical and pathological teams is essential for deciphering acute presentations where the etiology is uncertain. We highlight the clinical considerations, varied morphological pointers, and offer a diagnostic algorithm facilitating the consideration of this disease.

Abstract
OBJECTIVE To determine the relationships of red blood cell (RBC) transfusion and enteral feeding to changes in intestinal permeability (IP) measured by the relative intestinal uptake of lactulose (La) and rhamnose (Rh) in preterm infants <33 wk gestation. DESIGN/METHODS Infants 240-326wk gestation received La/Rh solution enterally on study days 1, 8 and 15.Urinary La/Rh ratio was measured by HPLC. Hematocrit preceding transfusion, total RBC transfusion volume, volume/kg, and feeding status during each study interval (birth-d1; d1-d8, and d8-d15) were determined. RESULTS Of the seventeen (40.5%) subjects who received≥1 transfusion during the study period, 12 (70.6%) infants were <28 wk gestation and 5 (29.4%) infants were≥28 wk gestation, p < 0.0001. Lower pre-transfusion hematocrit was observed in intervals preceding high IP (La/Rh > 0.05) than in intervals preceding low IP (La/Rh≤0.05) measurements (33 vs 35.8, p = 0.1051). RBC transfusions occurred more frequently in intervals preceding high IP than in intervals preceding low IP (26.8%; vs 8.3%, p = 0.0275) with 5-fold higher total RBC volume and volume/kg in intervals preceding any time point with high IP. RBC transfusion during an interval was associated with a three-fold increased risk of high IP (aOR 2.7; 95% C.I 0.564-12.814; p = 0.2143). Exclusive breast milk exposure and post-menstrual age reduced the risk for high IP following RBC transfusion. CONCLUSIONS Both RBC transfusion number and volume was associated with subsequent high IP measurements in preterm infants <33 weeks gestation and potentially may contribute to impairment of the preterm intestinal barrier.

Abstract
Coeliac artery stenosis (CAS) is rarely of consequence owing to rich collateral supply from the superior mesenteric artery via the pancreatic head. Pancreaticoduodenectomy (PD) in CAS disrupts these collaterals, and places the liver, stomach and spleen at risk of ischaemia. A 56-year-old man presented with a 3-week history of obstructive jaundice. Computed tomography revealed an operable periampullary tumour with CAS due to compression by the median arcuate ligament with multiple collaterals in the pancreatic head and a prominent gastroduodenal artery (GDA). Following unsuccessful coeliac axis endovascular stenting, a PD was performed. Intraoperative median arcuate ligament release failed to restore good flow in the common hepatic artery (CHA) and splenic artery (SpA) A decision was made to use the left gastric artery (LGA) for arterial reconstruction, disconnect it from the stomach with its origin intact and anastomose it to the supracoeliac aorta. Doppler ultrasonography with a GDA clamp confirmed good filling of the CHA and SpA via the LGA. The GDA was ligated and the PD completed. The patient had an uneventful recovery except for a biochemical pancreatic leak and was discharged on day 10. CAS during PD (confirmed by a decrease in CHA flow with a GDA clamp) requires an additional procedure to restore blood flow to the liver, stomach and spleen. Anastomosing the LGA to the supracoeliac aorta is a simple reconstruction technique for achieving this.

Abstract
Objective In the era of powerful immunosuppression, opportunistic infections are an increasing concern in systemic lupus erythematosus. One of the best-studied opportunistic infections is Pneumocystis pneumonia; however, the prevalence of Pneumocystis pneumonia in systemic lupus erythematosus is not clearly defined. This study evaluates the prevalence of Pneumocystis pneumonia in hospitalized systemic lupus erythematosus patients, with a focus on validating the Pneumocystis pneumonia and systemic lupus erythematosus diagnoses with clinical information. Methods This retrospective cohort study evaluates the prevalence of Pneumocystis pneumonia in all systemic lupus erythematosus patients treated at Columbia University Medical Center-New York Presbyterian Hospital between January 2000 and September 2014, using electronic medical record data. Patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and patients with renal transplants (including both early and late post-transplant patients) represented immunocompromised control groups. Patients with systemic lupus erythematosus, Pneumocystis pneumonia, HIV/AIDS, or renal transplant were identified using diagnostic codes from the International Classification of Diseases, Ninth Revision (ICD-9). Results Out of 2013 hospitalized systemic lupus erythematosus patients, nine had presumed Pneumocystis pneumonia, yielding a low prevalence of Pneumocystis pneumonia in systemic lupus erythematosus of 0.45%. Three of the nine Pneumocystis pneumonia cases were patients with concomitant systemic lupus erythematosus and HIV/AIDS. Only one of these nine cases was histologically confirmed as Pneumocystis pneumonia, in a patient with concomitant systemic lupus erythematosus and HIV/AIDS and a CD4 count of 13 cells/mm3. The prevalence of Pneumocystis pneumonia in renal transplant patients and HIV/AIDS patients was 0.61% and 5.98%, respectively. Conclusion Given the reported high rate of adverse effects to trimethoprim-sulfamethoxazole in systemic lupus erythematosus and the low prevalence of Pneumocystis pneumonia in hospitalized systemic lupus erythematosus patients, our data do not substantiate the need for Pneumocystis pneumonia prophylaxis in systemic lupus erythematosus patients, except in those with concurrent HIV/AIDS.

Abstract
BACKGROUND India has a high burden of active tuberculosis (TB) and human immunodeficiency virus (HIV) infection. Pregnancy increases the risks of developing TB in HIV-infected women. Isoniazid preventive therapy (IPT) reduces progression to TB, but may increase costs and hepatotoxicity. The cost-effectiveness of IPT for HIV-infected pregnant women in India is unknown. DESIGN We evaluated the cost-effectiveness of antepartum IPT among HIV-infected women in India using a decision-analytic model. We compared current practice (no IPT) with: Intervention 1 (IPT regardless of CD4 count) and Intervention 2 (IPT for those with CD4 count ⩿ 200 cells/μl). We modeled IPT irrespective of tuberculin skin test (TST) status and TST-driven strategies. Primary outcomes were anticipated costs, disability-adjusted life-years (DALYs) and TB cases. RESULTS Both IPT interventions are highly cost-effective compared to no IPT at current willingness-to-pay thresholds (respectively US$178.00 and US$201.00 per DALY averted for Interventions 1 and 2). However, providing IPT irrespective of CD4 count results in the greatest health benefits (21 TB cases averted/1000 patients) compared to current practice. IPT irrespective of TST status was also highly cost-effective compared to TST-driven IPT (respectively US$1027.00 and US$1154.00/DALY averted for Interventions 1 and 2). CONCLUSION Antepartum IPT for HIV-infected women is highly cost-effective for TB prevention compared to current practices in India.

Abstract
Mucopolysaccharidoses (MPS), a subgroup of lysosomal storage disorders, are caused due to deficiency of specific lysosomal enzyme involved in catabolism of glycosaminoglycans. To date more than 200 pathogenic variants in the alpha-l-iduronidase (IDUA) for MPS I and ∼500 pathogenic variants in the iduronate-2-sulphatase (IDS) for MPS II have been reported worldwide. The mutation spectrum of MPS type I and MPS type II disorders in Indian population is not characterized yet. In this study, we carried out clinical, biochemical, molecular and in silico analyses to establish the mutation spectrum of MPS I and MPS II in the Indian population. We conducted molecular analysis for 60 MPS-affected patients [MPS I (n = 30) (Hurler syndrome = 17, Hurler-Scheie syndrome = 13), and MPS II (n = 30) (severe = 18, attenuated = 12)] and identified a total of 44 [MPS I (n = 22) and MPS II (n = 22)] different pathogenic variants comprising missense, nonsense, frameshift, gross deletions and splice site variants. A total of 20 [MPS I (n = 14), and MPS II (n = 6)] novel pathogenic sequence variants were identified in our patient cohort. We found that 32% of pathogenic variants detected in IDUA were recurrent and 25% in MPS II. This is the first study revealing the mutation spectrum of MPS I and MPS II patients in the Indian population.

Abstract
Fibrodysplasia ossificans progressiva is a rare disorder of heterotopic ossification. Procedures like biopsy and surgery are known to be aggravating factors in promoting heterotopic ossification Clues to clinical diagnosis may therefore be a great advantage to treating orthopedician. Valgus deformity of great toe is an important diagnostic clue for treating physicians and thus aids in preventing the clinicians from subjecting the patients to unnecessary invasive and traumatic procedures. Hence clinical clues to early diagnosis are important in establishing the correct diagnosis and directing future management.

Abstract
A fascinating and important arbovirus is Ross River Virus (RRV) which is endemic and epizootic in nature in certain parts of the world. RRV is a member of the genus Alphavirus within the Semliki Forest complex of the family Togaviridae, which also includes the Getah virus. The virus is responsible for causing disease both in humans as well as horses. Mosquito species (Aedes camptorhynchus and Aedes vigilax; Culex annulirostris) are the most important vector for this virus. In places of low temperature as well as low rainfall or where there is lack of habitat of mosquito there is also limitation in the transmission of the virus. Such probability is higher especially in temperate regions bordering endemic regions having sub-tropical climate. There is involvement of articular as well as non-articular cells in the replication of RRV. Levels of pro-inflammatory factors viz., tumor necrosis factor-alpha (TNF-α); interferon-gamma (IFN-γ); and macrophage chemo-attractant protein-1 (MAC-1) during disease pathogenesis have been found to be reduced. Reverse transcription-polymerase chain reaction (RT-PCR) is the most advanced molecular diagnostic tool along with epitope-blocking enzyme-linked immunosorbent assay (ELISA) for detecting RRV infection. Treatment for RRV infection is only supportive. Vaccination is not a fruitful approach. Precise data collection will help the researchers to understand the RRV disease dynamics and thereby designing effective prevention and control strategy. Advances in diagnosis, vaccine development and emerging/novel therapeutic regimens need to be explored to their full potential to tackle RRV infection and the disease it causes.

Abstract
Mycelial growth in a defined medium by submerged fermentation is a rapid and alternative method for obtaining fungal biomass of consistent quality. Biomass, exopolysaccharides (EPS) and intracellular polysaccharides (IPS) production were optimised by response surface methodology in Lentinula edodes strain LeS (NCBI JX915793). The optimised conditions were pH 5.0, temperature 26°C, incubation period of 25 days and agitation rate of 52 r/min for L. edodes strain LeS. Under the calculated optimal culture conditions, biomass production (5.88 mg mL(-1)), EPS production (0.40 mg mL(-1)) and IPS production (12.45 mg g(-1)) were in agreement with the predicted values for biomass (5.93 mg mL(-1)), EPS (0.55 mg mL(-1)) and IPS production (12.64 mg g(-1)). Crude lentinan exhibited highest antibacterial effects followed by alcoholic, crude and aqueous extracts. The results obtained may be useful for highly effective yield of biomass and bioactive metabolites.

Abstract
OBJECTIVE To evaluate serum levels of rifampicin (RMP) in children with tuberculosis (TB) at doses administered according to India's Revised National Tuberculosis Control Programme (RNTCP) 2009 report. METHOD Prospective, open label, non-randomised single-dose study in 20 children aged 5-12 years. SETTING The out-patient chest clinic of a tertiary care hospital, New Delhi, India. RESULTS The median RMP dose administered was 9.56 mg/kg (range 9-12.64). Peak RMP concentration (Cmax) attained was 6.24 μg/ml (range 5.44-7.61) at time to Cmax of 3.5 h (range 3-4). RMP levels were significantly lower at 2, 3 and 4 h in children administered <10 mg/kg than those who received ⩾10 mg/kg (P < 0.05). A positive correlation between the RMP dose administered and Cmax was observed (r(2) = 0.748). RMP Cmax was <8 μg/ml in all patients, a level considered too low for therapeutic efficacy. CONCLUSIONS Low serum concentrations of RMP were attained in children under the RNTCP 2009 weight band system. Peak RMP levels appear to be lower and the single dose elimination half-life shorter in children than in adults. To optimise treatment outcomes, revisions in RMP dose in children should take into consideration age-related differences in pharmacokinetics.

Abstract
Background: The increasing usage of statins (the 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors) has revealed a number of unexpected beneficial effects, including a reduction in cancer risk. Methods: We investigated the direct anticancer effects of different statins approved for clinical use on human breast and brain cancer cells. We also explored the effects of statins on cancer cells using in silico simulations. Results: In vitro studies showed that cerivastatin, pitavastatin, and fluvastatin were the most potent anti-proliferative, autophagy inducing agents in human cancer cells including stem cell-like primary glioblastoma cell lines. Consistently, pitavastatin was more effective than fluvastatin in inhibiting U87 tumour growth in vivo. Intraperitoneal injection was much better than oral administration in delaying glioblastoma growth. Following statin treatment, tumour cells were rescued by adding mevalonate and geranylgeranyl pyrophosphate. Knockdown of geranylgeranyl pyrophosphate synthetase-1 also induced strong cell autophagy and cell death in vitro and reduced U87 tumour growth in vivo. These data demonstrate that statins main effect is via targeting the mevalonate synthesis pathway in tumour cells. Conclusions: Our study demonstrates the potent anticancer effects of statins. These safe and well-tolerated drugs need to be further investigated as cancer chemotherapeutics in comprehensive clinical studies.
